or financial condition or results of operation of the Company and its
subsidiaries taken as a whole.. The Company is obligated to file reports
pursuant to Section 15(d) of the 1934 Act. The Common Stock is listed and traded

the Registration Rights Agreement by the Company, the issuance of the

contemplated by this Agreement, the Registration Rights Agreement, and the
Debenture do not and will not conflict with or result in a breach by the Company
of any of the terms or provisions of, or constitute a default under (i) the
certificate of incorporation or by-laws of the Company, each as currently in

<PAGE>

Common Stock declines prior to the conversion of the Debenture. The Company's
executive officers and directors have studied and fully understand the nature of
the Securities being sold hereby and recognize that they have a potential
dilutive effect. The board of directors of the Company has concluded, in its
good faith business judgment that such issuance is in the best interests of the
Company. The Company specifically acknowledges that its obligation to issue the
Shares upon conversion of the Debenture is binding upon the Company and
enforceable regardless of the dilution such issuance may have on the ownership
interests of other shareholders of the Company, and the Company will honor every
Notice of Conversion (as defined in the Debenture) relating to the conversion of
the Debenture unless the Company is subject to an injunction (which injunction

Company).

type contemplated in this Section 3(p) that may be due in connection with the

each of Buyer, its employees, officers, directors, agents, and partners, and
their respective affiliates, from and against all claims, losses, damages, costs
(including the costs of preparation and attorney's fees) and expenses suffered

                                       7
<PAGE>

even if the 1934 Act or the rules and regulations thereunder would permit such
termination. The Company will take all reasonable action under its control to
obtain and to continue the listing and trading of its Common Stock (including,
without limitation, all Registrable Securities) on the Over The Counter Bulletin
Board Market and will comply in all material respects with the Company's
reporting, filing and other obligations under the by-laws or rules of the
National Association of Securities Dealers, Inc. ("NASD") or the Over The
Counter Bulletin Board Market.

         F. USE OF PROCEEDS. The Company will use the proceeds from the sale of
the Debenture (excluding amounts paid by the Company for legal fees, finder's
fees and escrow fees in connection with the sale of the Debenture) for internal
working capital purposes, and, unless specifically consented to in advance in
each instance by the Buyer, the Company shall not, directly or indirectly, use
such proceeds for any loan to or investment in any other corporation,
partnership enterprise or other person or for the repayment of any outstanding
loan by the Company to any other party.

         G. AVAILABLE SHARES. The Company shall have at all times authorized and
reserved for issuance, free from preemptive rights, shares of Common Stock
sufficient to yield the aggregate of one hundred twenty percent (120%) of the
number of shares of Common Stock issuable at conversion as may be required to
satisfy the conversion rights of the Buyer pursuant to the terms and conditions
of the Debenture.

         H. LIMITATION ON ISSUANCE OF SHARES. If applicable to the Company, the
Company may be limited in the number of shares of Common Stock it may issue by
virtue of (i) the number of authorized shares or (ii) the applicable rules and
regulations of the principal securities market on which the Common Stock is
listed or traded (collectively, the "Cap Regulations"). Without limiting the
other provisions thereof, the Debenture shall provide that (i) the Company will
take all steps reasonably necessary to be in a position to issue shares of
Common Stock on conversion of the Debenture without violating the Cap
Regulations and (ii) if, despite taking such steps, the Company still can not
issue such shares of Common Stock without violating the Cap Regulations, the
holder of a Debenture which can not be converted as result of the Cap
Regulations (each such Debenture, an "Unconverted Debenture") shall have the
option, exercisable in such holder's sole and absolute discretion, to elect
either of the following remedies:

                  (x) if permitted by the Cap Regulations, require the Company
         to issue shares of Common Stock in accordance with such holder's notice
         of conversion at a conversion purchase price equal to the average of
         the closing price per share of Common Stock for any five (5)
         consecutive trading days (subject to certain equitable adjustments for
         certain events occurring during such period) during the sixty (60)
         trading days immediately preceding the date of notice of conversion; or

                  (y) require the Company to redeem each Unconverted Debenture
         for an amount (the "Cap Redemption Amount"), payable in cash, equal to
         (i) one hundred ten percent (110.0%) of the principal of the
         Unconverted Debenture, plus (ii) all accrued but unpaid interest on the
         Debenture through the date of redemption (the "Cap Redemption Date")
         specified in the notice from the holder electing this remedy.

A holder of an Unconverted Debenture may elect one of the above remedies with
respect to a portion of such Unconverted Debenture and the other remedy with
respect to other portions of the Unconverted Debenture. The Debenture shall
contain provisions substantially consistent with the above terms, with such
additional provisions as may be consented to by the Buyer. The provisions of
this paragraph are not intended to limit the scope of the provisions otherwise
included in the Debenture.

5.       TRANSFER AGENT INSTRUCTIONS.

         A. The Company warrants that, with respect to the Securities, other
than the stop transfer instructions to give effect to Section 4(a) hereof, it
will give its transfer agent no instructions inconsistent with instructions to
issue Common Stock from time to time upon conversion of the Debenture in such
amounts as specified from time to time by the Company to the transfer agent,
bearing the restrictive legend specified in Section 4(b) of this Agreement prior
to registration of the Shares under the 1933 Act, registered in the name of the
Buyer or its nominee and in such denominations to be specified by the Buyer in
connection with each conversion of the Debenture. Except as so provided, the
Shares shall otherwise be freely transferable on the books and records of the
Company as and to the extent provided in this Agreement, the Registration Rights
Agreement, and applicable law. Nothing in this Section shall affect in any way
the Buyer's obligations and agreement to comply with all applicable securities
laws upon resale of the Securities. If the Buyer provides the Company with an
opinion of counsel reasonably satisfactory to the Company that registration of a
resale by the Buyer of any of the Securities in accordance with clause (1)(B) of
Section 4(a) of this Agreement is not required under the 1933 Act, the Company
shall (except as provided in clause (2) of Section 4(a) of this Agreement)
permit the transfer of the Securities and, in the case of the Converted Shares,
promptly instruct the Company's transfer agent to issue one or more certificates
for Common Stock without legend in such name and in such denominations as
specified by the Buyer.

         B. Subject to the provisions of this Agreement, the Company will permit
the Buyer to exercise its right to convert the Debenture in the manner
contemplated by the Debenture.

         C. The Company will authorize its transfer agent to give information
relating to the Company directly to the Buyer or the Buyer's representatives
upon the request of the Buyer or any such representative, to the extent such
information relates to (i) the status of shares of Common Stock issued or
claimed to be issued to the Buyer in connection with a Notice of Conversion, or
(ii) the number of outstanding shares of Common Stock of all stockholders as of
a current or other specified date. The Company will provide the Buyer with a
copy of the authorization so given to the transfer agent. While the Company will
use its best efforts to effectuate the transfer agent's compliance with such
authorization, the Company will not be responsible for the transfer agent's
failure to do so.

6.       CLOSING DATE.

         A. The Closing Date shall occur on the date which is the first NYSE

makes it impracticable or inadvisable to purchase the Debenture.

         HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED,

                          ADVANCED VIRAL RESEARCH CORP.

                   5% CONVERTIBLE DEBENTURE DUE JULY 15, 2004

        THIS DEBENTURE is issued by ADVANCED VIRAL RESEARCH CORP., a corporation
organized and existing under the laws of the State of Delaware (the "Company")
and is designated as its 5% Convertible Debenture, pursuant to a Securities
Purchase Agreement dated as of July 15, 2002 by and between the Company and the
Purchasers identified therein (the "Securities Purchase Agreement"). Capitalized
terms used but not defined herein shall have the meanings set forth in the
Securities Purchase Agreement.

1.       AGREEMENT TO SUBSCRIBE AND PURCHASE PRICE.

         FOR VALUE RECEIVED, the Company promises to pay to PETER LUNDER, the
registered holder hereof (the "Holder"), the principal sum of One Million and
00/100 Dollars (US $500,000) on July 15, 2004 (the "Maturity Date") and to pay
interest on the principal sum outstanding in arrears (i) prior to the Maturity
Date, upon conversion as provided herein or (ii) on the Maturity Date, at the
rate of 5% per annum accruing from July 15, 2002, the date of initial issuance
of this Debenture. Accrual of interest shall commence on the first such business
day to occur after the date hereof and shall continue to accrue on a daily basis
until payment in full of the principal sum has been made or duly provided for.
The payment of accrued and unpaid interest shall be made in shares of Common
Stock at the Conversion Rate (as defined below) as of the Conversion Date or the
Maturity Date, as the case may be. No fractional shares of Common Stock or scrip
representing fractions of shares will be issued on conversion, but the number of
shares issuable shall be rounded to the nearest whole share.

2.       TERMS OF CONVERSION OF DEBENTURE

         (a) TERMS OF CONVERSION. The principal balance of this Debenture shall
be convertible by the Holder into shares of Common Stock as follows: 20%
commencing on the original issuance date of this Debenture, and an additional
20% commencing every six months thereafter. For purposes of this Debenture and
the Securities Purchase Agreement, the date upon which each such 20% of the
principal balance of the Debenture becomes convertible shall be referred to as a
"Vesting Date."

                                       1
<PAGE>

         (b) CONVERSION RATE. The Holder of this Debenture is entitled, at its
option, subject to the following provisions of this Section, to convert this
Debenture into shares of Common Stock of the Company at a conversion price for
each share of Common Stock ("Conversion Rate") equal to:

                  (i)      for the first 20% of the principal balance of this
                           Debenture, $0.1818 per share; and

                  (ii)     for each additional 20% of the principal balance of
                           this Debenture, the higher of (A) ninety percent
                           (90%) of the Market Price (as defined below) on the
                           Conversion Date (as defined below) or (B) ten cents
                           ($0.10) which amount is subject to adjustment as
                           provided herein.

For purposes of this Debenture, the term "Market Price" means the average
closing bid price of the Common Stock during the five (5) trading days ending on
the trading day immediately before the Conversion Date (as reported by
Bloomberg, LP or, if not so reported, as reported on the over-the-counter
market).

         (c) MANNER OF CONVERSION. Conversion shall be effectuated by faxing a
Notice of Conversion to the Company in the form annexed hereto as EXHIBIT A (the
"Notice of Conversion"). The Notice of Conversion shall be executed by the
Holder of this Debenture and shall evidence such Holder's intention to convert
this Debenture or a specified portion hereof. Interest accrued or accruing from
the date of issuance to the date of conversion or to the Maturity Date, as the
case may be, shall be paid in shares of Common Stock at the Conversion Rate then
applicable as of the Conversion Date or the Maturity Date, as the case may be.
No fractional shares of Common Stock or scrip representing fractions of shares
will be issued on conversion, but the number of shares issuable shall be rounded
to the nearest whole share. The date on which notice of conversion is given (the
"Conversion Date") shall be deemed to be the date on which the Holder faxes or
otherwise delivers the Notice of Conversion to the Company so that it is
received by the Company on or before such specified date, provided that, if such
conversion would convert the entire remaining principal of this Debenture, the
Holder shall deliver to the Company the original Debenture being converted no
later than five (5) business days thereafter. Facsimile delivery of the Notice
of Conversion shall be accepted by the Company at facsimile number (914)
376-7368; Attn: President. Certificates representing Common Stock upon
conversion will be delivered to the Holder at the address specified in the
Notice of Conversion (which may be the Buyer's address for notices as
contemplated by the Securities Purchase Agreement or a different address), via
express courier, by electronic transfer or otherwise, within three (3) business
days if the address for delivery is in the United States and within five (5)
business days if the address for delivery is outside the United States (such
third business day or fifth business day, as the case may be, the "Delivery
Date") after the date on which the Notice of Conversion is delivered to the
Company.

         (d) AUTOMATIC CONVERSION. Any principal amount of this Debenture not
previously converted or redeemed as of the Maturity Date, shall be deemed to be
automatically converted, without further action of any kind (including, but not
necessarily limited to, the giving of a Notice of Conversion) by the Holder, as
of the Maturity Date at the Conversion Rate applicable on the Maturity Date
("Mandatory Conversion").

         (e) TAXES WITHHELD. The Company shall be entitled to withhold from all
payments of principal of, and interest on, this Debenture any amounts required
to be withheld under the applicable provisions of the United States income tax
laws or other applicable laws at the time of such payments, and Holder shall
execute and deliver all required documentation in connection therewith.

<PAGE>

         (f) COMPLIANCE WITH SECURITIES ACT OF 1933. This Debenture has been
issued subject to investment representations of the original purchaser hereof
and may be transferred or exchanged only in compliance with the Securities Act
of 1933, as amended (the "Act"), other applicable state and foreign securities
laws and the terms of the Securities Purchase Agreement. In the event of any
proposed transfer of this Debenture, the Company may require, prior to issuance
of a new Debenture in the name of such other person, that it receive reasonable
transfer documentation including legal opinions from counsel reasonably
acceptable to the Company in form and substance reasonably acceptable to the
Company that the issuance of this Debenture in such other name does not and will
not cause a violation of the Act or any applicable state or foreign securities
laws. Prior to due presentment for transfer of this Debenture, the Company and
any agent of the Company may treat the person in whose name this Debenture is
duly registered on the Company's Debenture Register as the owner hereof for the
purpose of receiving payment as herein provided and for all other purposes,
whether or not this Debenture be overdue, and neither the Company nor any such
agent shall be affected by notice to the contrary.

3.       REDEMPTION OF DEBENTURE.

         (a) RIGHT TO REDEEM. Notwithstanding any other provision hereof to the
contrary, at any time prior to the Conversion Date, the Company shall have the
right to redeem all or any portion of the then outstanding principal amount of
this Debenture then held by the Holder in shares of Common Stock at the
Conversion Rate as of the date of the Notice of Redemption (as defined below),
for an amount (the "Redemption Amount") equal to the sum of (a) one hundred ten
percent (110%) of the outstanding principal of such Debenture plus (b) all
accrued but unpaid interest thereon through the date the Redemption Amount is
paid to the Holder (the "Redemption Payment Date").

         (b) NOTICE OF REDEMPTION. The Company shall give at least five (5)
business days' written notice of such redemption to the Holder (the "Notice of
Redemption"). The date so specified in such Notice of Redemption shall be the
Redemption Payment Date. Anything in the preceding provisions of this Section to
the contrary notwithstanding, the Redemption Amount shall, unless otherwise
agreed to in writing by the Holder after receiving the Notice of Redemption, be
paid to the Holder in good funds at least five (5) but not more than ten (10)
business days from the date of the Notice of Redemption, except that the Holder
shall have the right, exercisable by giving a Notice of Conversion is submitted
to the Company within five (5) business days of the Holder's receipt of the
Company's Notice of Redemption, to convert all or any portion of this Debenture
(a "Redemption Notice Conversion") and the Redemption Notice Conversion shall
take precedence over the redemption contemplated by the Notice of Redemption.
This Debenture shall be converted in accordance with the terms hereof.

4.       LIMITATIONS ON ISSUANCE; CAP REGULATIONS.

         (a) CAP REGULATIONS. The Holder recognizes that, if applicable to the
Company, the Company may be limited in the number of shares of Common Stock it
may issue by virtue of (a) the number of authorized shares, or (b) the
applicable rules and regulations of the principal securities market on which the
Common Stock is listed or traded (collectively, the "Cap Regulations"). Without
limiting the other provisions hereof, (w) the Company will take all steps
reasonably necessary to be in a position to issue shares of Common Stock on
conversion of this Debenture without violating the Cap Regulations and (x) if,
despite taking such steps, the Company still can not issue such shares of Common
Stock without violating the Issuance Regulations, the Holder of this Debenture
(to the extent the same can not be converted in compliance with the Issuance
Regulations (an "Unconverted Debenture"), shall have the option, exercisable in
such Holder's sole and absolute discretion, to elect either of the following
remedies:

<PAGE>

                  (i) if permitted by the Cap Regulations, require the Company
         to issue shares of Common Stock in accordance with such holder's notice
         of conversion at a conversion purchase price equal to the average of
         the closing price per share of Common Stock for any five (5)
         consecutive trading days (subject to certain equitable adjustments for
         certain events occurring during such period) during the sixty (60)
         trading days immediately preceding the date of notice of conversion; or

                  (ii) require the Company to redeem each Unconverted Debenture
         for an amount equal to the Redemption Amount, based on the date of
         redemption (the "Cap Redemption Date") specified in the notice from the
         Holder electing this remedy.

         (b) NOTICE. The notice of exercise of this provision by the Holder
shall specify the Cap Redemption Date, which shall be at least five (5) business
days after the date of such notice; provided, however, that the Company shall
have the right to accelerate the Cap Redemption Date. The Holder of an
Unconverted Debenture may elect one of the above remedies with respect to a
portion of such Unconverted Debenture and the other remedy with respect to other
portions of the Unconverted Debenture.

5.       EVENTS OF DEFAULT.   The following shall constitute an "Event of
Default":

         (a) The Company shall default in the payment of principal or interest
on this Debenture upon the terms hereof and same shall continue for a period of
five (5) business days; or

         (b) Any of the representations or warranties made by the Company
herein, in the Securities Purchase Agreement, the Registration Rights Agreement
or in any certificate or financial or other written statements heretofore or
hereafter furnished by the Company in connection with the execution and delivery
of this Debenture or the Securities Purchase Agreement shall be false or
misleading in any material respect at the time made; or

         (c) Subject to the terms of the Securities Purchase Agreement, the
Company fails to authorize or to cause its Transfer Agent to issue shares of
Common Stock upon exercise by the Holder of the conversion rights of the Holder
in accordance with the terms of this Debenture, fails to transfer or to cause
its Transfer Agent to transfer any certificate for shares of Common Stock issued
to the Holder upon conversion of this Debenture and when required by this
Debenture or the Registration Rights Agreement, and such transfer is otherwise
lawful, or fails to remove any restrictive legend on any certificate or fails to
cause its Transfer Agent to remove such restricted legend, in each case where
such removal is lawful, as and when required by this Debenture, the Agreement or
the Registration Rights Agreement, and any such failure shall continue uncured
for ten (10) business days; or

         (d) The Company shall fail to perform or observe, in any material
respect, any other covenant, term, provision, condition, agreement or obligation
of any Debenture in this series and such failure shall continue uncured for a
period of thirty (30) days after written notice from the Holder of such failure;
or

         (e) The Company shall fail to perform or observe, in any material
respect, any covenant, term, provision, condition, agreement or obligation of
the Company under the Securities Purchase Agreement or the Registration Rights
Agreement and such failure shall continue uncured for a period of thirty (30)
days after written notice from the Holder of such failure (other than a failure
to use the Company's best efforts to cause the Registration Statement to become
effective, as provided in the Registration Rights Agreement, as to which the
cure period shall be five (5) days after written notice from the Holder of such
failure); or

                                       4
<PAGE>

         (f) The Company shall make an assignment for the benefit of creditors
or commence proceedings for its dissolution; or apply for or consent to the
appointment of a trustee, liquidator or receiver for its or for a substantial
part of its property or business; or

         (g) A trustee, liquidator or receiver shall be appointed for the
Company or for a substantial part of its property or business without its
consent and shall not be discharged within ninety (90) days after such
appointment; or

         (h) Any governmental agency or any court of competent jurisdiction at
the instance of any governmental agency shall assume custody or control of the
whole or any substantial portion of the properties or assets of the Company and
shall not be dismissed within ninety (90) days thereafter; or

         (i) Any money judgment, writ or warrant of attachment, or similar
process in excess of One Million Dollars ($1,000,000) in the aggregate shall be
entered or filed against the Company or any of its properties or other assets
and shall remain unpaid, unvacated, unbonded or unstayed for a period of sixty
(60) days or in any event later than five (5) days prior to the date of any
proposed sale thereunder; or

         (j) Bankruptcy, reorganization, insolvency or liquidation proceedings

consent to, or acquiesce in any such proceedings or admit the material
allegations of, or default in answering a petition filed in any such proceeding;
or

         (k) The Company shall have its Common Stock suspended or delisted from
an exchange or over-the-counter market from trading for in excess of fifteen
(15) trading days.

Then, or at any time thereafter, and in each and every such case, unless such
Event of Default shall have been waived in writing by the Holder (which waiver
shall not be deemed to be a waiver of any subsequent default) at the option of
the Holder and in the Holder's sole discretion, the Holder may consider this
Debenture immediately due and payable in shares of Common Stock at the
Conversion Rate then applicable, without presentment, demand, protest or notice
of any kinds, all of which are hereby expressly waived, anything herein or in
any note or other instruments contained to the contrary notwithstanding, and the
Holder may immediately enforce any and all of the Holder's rights and remedies
provided herein or any other rights or remedies afforded by law.

6.       NO USURY.

         In the event for any reason, any payment by or act of the Company or
the Holder shall result in payment of interest which would exceed the limit
authorized by or be in violation of the law of the jurisdiction applicable to
this Debenture, then IPSO FACTO the obligation of the Company to pay interest or
perform such act or requirement shall be reduced to the limit authorized under
such law, so that in no event shall the Company be obligated to pay any such
interest, perform any such act or be bound by any requirement which would result
in the payment of interest in excess of the limit so authorized. In the event
any payment by or act of the Company shall result in the extraction of a rate of
interest in excess of a sum which is lawfully collectible as interest, then such
amount (to the extent of such excess not returned to the Company) shall, without

                                       5
<PAGE>

further agreement or notice between or by the Company or the Holder, be deemed
applied to the payment of principal, if any, hereunder immediately upon receipt
of such excess funds by the Holder, with the same force and effect as though the
Company had specifically designated such sums to be so applied to principal and
the Holder had agreed to accept such sums as an interest-free prepayment of this
Debenture. If any part of such excess remains after the principal has been paid
in full, whether by the provisions of the preceding sentences of this Section or
otherwise, such excess shall be deemed to be an interest-free loan from the
Company to the Holder, which loan shall be payable immediately upon demand by
the Company. The provisions of this Section shall control every other provision
of this Debenture.

7.       MISCELLANEOUS.

         (a) NO RECOURSE. No recourse shall be had for the payment of the
principal of, or the interest on, this Debenture, or for any claim based hereon,
or otherwise in respect hereof, against any incorporator, shareholder, officer
or director, as such, past, present or future, of the Company or any successor
corporation, whether by virtue of any constitution, statute or rule of law, or
by the enforcement of any assessment or penalty or otherwise, all such liability
being, by the acceptance hereof and as part of the consideration for the issue
hereof, expressly waived and released.

         (b) METHOD OF PAYMENTS OF COMMON STOCK. Each delivery of shares of
Common Stock issuable to the Holder as contemplated hereby shall be made to the
Holder at the address last appearing on this Debenture Register of the Company
as designated in writing by the Holder from time to time; except that the Holder
can designate, by notice to the Company, a different delivery address for any
one or more specific payments or deliveries.

         (c) CHANGE OF CONTROL. If, for as long as this Debenture remains
outstanding, the Company enters into a merger (other than where the Company is
the surviving entity) or consolidation with another corporation or other entity
or a sale or transfer of all or substantially all of the assets of the Company
to another person (collectively, a "Sale"), the Company will require, in the
agreements reflecting such transaction, that the surviving entity expressly
assume the obligations of the Company hereunder. Notwithstanding the foregoing,
if the Company enters into a Sale and the holders of the Common Stock are
entitled to receive stock, securities or property in respect of or in exchange
for Common Stock, then as a condition of such Sale, the Company and any such
successor, purchaser or transferee will agree that this Debenture may thereafter
be converted on the terms and subject to the conditions set forth above into the
kind and amount of stock, securities or property receivable upon such merger,
consolidation, sale or transfer by a holder of the number of shares of Common
Stock into which this Debenture might have been converted immediately before
such merger, consolidation, sale or transfer, subject to adjustments which shall
be as nearly equivalent as may be practicable. In the event of any such proposed
Sale, (i) the Holder hereof shall have the right to convert by delivering a
Notice of Conversion to the Company within fifteen (15) days of receipt of
notice of such Sale from the Company, except that Section 2(e) shall not apply
to such conversion.

         (d) STOCK SPLITS. If, at any time while any portion of this Debenture
remains outstanding, the Company effectuates a stock split or reverse stock
split of its Common Stock or issues a dividend on its Common Stock consisting of
shares of Common Stock, the Conversion Rate shall be equitably adjusted to
reflect such action. By way of illustration, and not in limitation, of the
foregoing (i) if the Company effectuates a 2:1 split of its Common Stock,
thereafter, with respect to any conversion for which the Company issues the
shares after the record date of such split, the Conversion Rate shall be deemed
to be one-half of what it had been calculated to be immediately prior to such
split; (ii) if the Company effectuates a 1:10 reverse split of its Common Stock,
thereafter, with respect to any conversion for which the Company issues the
shares after the record date of such reverse split, the Conversion Rate shall be
deemed to be ten times what it had been calculated to be immediately prior to
such split; and (iii) if the Company declares a stock dividend of one share of
Common Stock for every 10 shares outstanding, thereafter, with respect to any
conversion for which the Company issues the shares after the record date of such

                                       6
<PAGE>

dividend, the Conversion Rate shall be deemed to be the amount of such
Conversion Rate calculated immediately prior to such record date multiplied by a
fraction, of which the numerator is the number of shares (10) for which a
dividend share will be issued and the denominator is such number of shares plus
the dividend share(s) issuable or issued thereon (11).

         (e) REPRESENTATIONS OF HOLDER. The Holder of this Debenture, by
acceptance hereof, agrees that this Debenture is being acquired for investment
and that such Holder will not offer, sell or otherwise dispose of this Debenture
or the Shares of Common Stock issuable upon conversion thereof except under
circumstances which will not result in a violation of the Act or any applicable
state Blue Sky or foreign laws or similar laws relating to the sale of
securities.

         (f) NO RIGHT TO VOTE OR TO RECEIVE DIVIDENDS. Nothing contained in this
Debenture shall be construed as conferring upon the Holder the right to vote or
to receive dividends or to consent or receive notice as a shareholder in respect
of any meeting of shareholders or any rights whatsoever as a shareholder of the
Company, unless and to the extent converted in accordance with the terms hereof.

         (g) GOVERNING LAW. This Debenture shall be governed by and construed in
accordance with the laws of the State of New York. Each of the parties consents
to the jurisdiction of the federal courts whose districts encompass any part of
the City of New York or the state courts of the State of New York sitting in the
City of New York in connection with any dispute arising under this Agreement and
hereby waives, to the maximum extent permitted by law, any objection, including
any objection based on FORUM NON COVENIENS, to the bringing of any such
proceeding in such jurisdictions. To the extent determined by such court, the
Company shall reimburse the Holder for any reasonable legal fees and
disbursements incurred by the Holder in enforcement of or protection of any of
its rights under any of this Debenture.

         IN WITNESS WHEREOF, the Company has caused this instrument to be duly
executed by an officer thereunto duly authorized.

                  THIS REGISTRATION RIGHTS AGREEMENT, dated as of July 15,
2002 (this "Agreement"), is made by and between ADVANCED VIRAL RESEARCH CORP., a

         WHEREAS, upon the terms and subject to the conditions of the Securities
Purchase Agreement, dated as of JuneJuly 15, 2002, between the Investor and the
Company (the "Securities Purchase Agreement"; capitalized terms not otherwise
defined herein shall have the meanings ascribed to them in the Securities
Purchase Agreement), the Company has agreed to issue and sell to the Investor
its 5% Convertible Debenture in the principal amount of $500,000 (the
"Debenture"); and

         WHEREAS, the Debenture is convertible into shares of Common Stock (the
"Conversion Shares"; which term, for purposes of this Agreement, shall include
shares of Common Stock of the Company issuable in lieu of accrued interest on
conversion as contemplated by the Debenture) upon the terms and subject to the
conditions contained in the Debenture; and

         WHEREAS, to induce the Investor to execute and deliver the Securities
Purchase Agreement, the Company has agreed to provide certain registration
rights under the Securities Act of 1933, as amended, and the rules and
regulations thereunder, or any similar successor statute (collectively, the
"Securities Act"), with respect to the Conversion Shares;

         NOW, THEREFORE, in consideration of the premises and the mutual
covenants contained herein and other good and valuable consideration, the
receipt and sufficiency of which are hereby acknowledged, the Company and the
Investor hereby agree as follows:

         1. DEFINITIONS. As used in this Agreement, the following terms shall
have the following meanings:

                  (a) "Potential Material Event" means any of the following: (i)
the possession by the Company of material information not ripe for disclosure in
a registration statement, which shall be evidenced by determinations in good
faith by the Board of Directors of the Company that disclosure of such
information in the registration statement would be detrimental to the business
and affairs of the Company; or (ii) any material engagement or activity by the
Company which would, in the good faith determination of the Board of Directors
of the Company, be adversely affected by disclosure in a registration statement
at such time, which determination shall be accompanied by a good faith

                                       1
<PAGE>

determination by the Board of Directors of the Company that the registration
statement would be materially misleading absent the inclusion of such
information.

                  (b) "Register," "Registered," and "Registration" refer to a
registration effected by preparing and filing a Registration Statement or
Statements in compliance with the Securities Act and pursuant to Rule 415 under
the Securities Act or any successor rule providing for offering securities on a
continuous basis ("Rule 415"), and the declaration or ordering of effectiveness
of such Registration Statement by the United States Securities and Exchange
Commission (the "SEC").

                  (c) "Registrable Securities" means the Conversion Shares.

                  (d) "Registration Statement" means a registration statement of
the Company under the Securities Act.

         2.       REGISTRATION.

                  (a) The Company shall use its best efforts to prepare and file
with the SEC as soon as possible after the Closing Date either a Registration
Statement on Form S-1or an amendment to an existing Registration Statement, in
either event registering for resale by the Investor a sufficient number of
shares of Common Stock for the Investor to sell the Registrable Securities (or
such lesser number as may be required by the SEC, but in no event less than the
aggregate number of shares equal to (A) one hundred twenty percent (120%) of the
number of shares into which the principal of the Debenture would be convertible
at the time of filing of such Registration Statement (assuming for such purposes
that the Debenture had been eligible to be converted, and had been converted
into Conversion Shares in accordance with their terms, whether or not such
issuance, eligibility or conversion had in fact occurred as of such date). The
Registration Statement shall state that, in accordance with Rule 416 and 457
under the Securities Act, it also covers such indeterminate number of additional
shares of Common Stock as may become issuable upon conversion of the Debenture
to prevent dilution resulting from stock splits, or stock dividends.

                  (b) If at any time (an "Increased Registered Shares Date"),
the number of shares of Common Stock represented by the Registrable Shares,
issued or to be issued as contemplated by the Transaction Agreements, exceeds
the aggregate number of shares of Common Stock then registered, the Company
shall, within ten (10) business days after receipt of a written notice from any
Investor, either

                           (X) amend the Registration Statement filed by the
                  Company pursuant to the preceding provisions of this Section
                  2, if such Registration Statement has not been declared
                  effective by the SEC at that time, to register, in the
                  aggregate, at least the number of shares (the "Increased
                  Shares Amount") equal to (A) the number of shares theretofore
                  issued on conversion of the Debenture (including any interest
                  paid on conversion by the issuance of Conversion Shares), plus
                  (B) the sum of (I) __________ one hundred twenty (120___%) of
                  the number of shares into which the then unconverted Debenture
                  would be convertible at the time of relevant filing with the
                  SEC or as of the Increased Registered Shares Date, whichever
                  is higher computed as contemplated by the immediately
                  preceding subparagraph (a), or

                           (Y) if such Registration Statement has been declared
                  effective by the SEC at that time, file with the SEC an
                  additional Registration Statement on Form S-1 or other
                  appropriate registration statement form (an "Additional

                                       2
<PAGE>

                  Registration Statement") to register the number of shares
                  equal to the excess of the Increased Shares Amount over the
                  aggregate number of shares of Common Stock already registered.

         3. OBLIGATIONS OF THE COMPANY. In connection with the registration of
the Registrable Securities, the Company shall do each of the following:

                  (a) Prepare promptly, and file with the SEC a Registration
Statement with respect to not less than the number of Registrable Securities
provided in Section 2 above, and thereafter use its reasonable best efforts to
cause such Registration Statement relating to Registrable Securities to become
effective and keep the Registration Statement effective at all times during the
period (the "Registration Period") continuing until the earliest of (i) the date
that is fourtwo (42) years after the last day of the calendar month following
the month in which the Effective Date occurs, (ii) the date when the Investor
may sell all Registrable Securities under Rule 144 without volume or other
restrictions or limits or (iii) the date the Investor no longer owns any of the
Registrable Securities, which Registration Statement (including any amendments
or supplements thereto and prospectuses contained therein) shall not contain any
untrue statement of a material fact or omit to state a material fact required to
be stated therein or necessary to make the statements therein, in light of the
circumstances in which they were made, not misleading;

                  (b) Prepare and file with the SEC such amendments (including
post-effective amendments) and supplements to the Registration Statement and the
prospectus used in connection with the Registration Statement as may be
necessary to keep the Registration Statement effective at all times during the
Registration Period, and, during the Registration Period, comply with the
provisions of the Securities Act with respect to the disposition of all
Registrable Securities of the Company covered by the Registration Statement
until such time as all of such Registrable Securities have been disposed of in
accordance with the intended methods of disposition by the seller or sellers
thereof as set forth in the Registration Statement;

                  (c) Permit a single firm of counsel designated by the Investor
to review the Registration Statement and all amendments and supplements thereto
a reasonable period of time (but not less than three (3) business days) prior to
their filing with the SEC, and not file any document in a form to which such
counsel reasonably objects;

                  (d) Notify Investor, such Investor's legal counsel identified
to the Company and which has requested by written notice to the Company that it
receive such notification (which, until further notice, shall be deemed to be
___________, which firm has requested to receive such notification ("Investor's
Counsel"); and any managing underwriters immediately (and, in the case of (i)(A)
below, not less than two (2) business days prior to such filing) and (if
requested by any such Person) confirm such notice in writing no later than one
(1) business day following the day (i)(A) when a Prospectus or any Prospectus
supplement or post-effective amendment to the Registration Statement is proposed
to be filed; (B) whenever the SEC notifies the Company whether there will be a
"review" of such Registration Statement; (C) whenever the Company receives (or a
representative of the Company receives on its behalf) any oral or written
comments from the SEC in respect of a Registration Statement (copies or, in the
case of oral comments, summaries of such comments shall be promptly furnished by
the Company to the Investor); and (D) with respect to the Registration Statement
or any post-effective amendment, when the same has become effective; (ii) of any
request by the SEC or any other Federal or state governmental authority for
amendments or supplements to the Registration Statement or Prospectus or for
additional information; (iii) of the issuance by the SEC of any stop order
suspending the effectiveness of the Registration Statement covering any or all
of the Registrable Securities or the initiation of any proceedings for that
purpose; (iv) if at any time any of the representations or warranties of the
Company contained in any agreement (including any underwriting agreement)

                                       3
<PAGE>

contemplated hereby ceases to be true and correct in all material respects; (v)
of the receipt by the Company of any notification with respect to the suspension
of the qualification or exemption from qualification of any of the Registrable
Securities for sale in any jurisdiction, or the initiation or threatening of any
proceeding for such purpose; and (vi) of the occurrence of any event that to the
best knowledge of the Company makes any statement made in the Registration
Statement or Prospectus or any document incorporated or deemed to be
incorporated therein by reference untrue in any material respect or that
requires any revisions to the Registration Statement, Prospectus or other
documents so that, in the case of the Registration Statement or the Prospectus,
as the case may be, it will not contain any untrue statement of a material fact
or omit to state any material fact required to be stated therein or necessary to
make the statements therein, in light of the circumstances under which they were
made, not misleading. In addition, the Company shall furnish the Investor with
copies of all intended written responses to the comments contemplated in clause
(C) of this Section 3(d) not later than one (1) business day in advance of the
filing of such responses with the SEC so that the Investor shall have the
opportunity to comment thereon;

                  (e) Furnish to Investor and Investor's Counsel (i) promptly
after the same is prepared and publicly distributed, filed with the SEC, or
received by the Company, one (1) copy of the Registration Statement, each
preliminary prospectus and prospectus, and each amendment or supplement thereto,
and (ii) such number of copies of a prospectus, and all amendments and
supplements thereto and such other documents, as such Investor may reasonably
request in order to facilitate the disposition of the Registrable Securities
owned by such Investor;

                  (f) As promptly as practicable after becoming aware thereof,
notify Investor of the happening of any event of which the Company has
knowledge, as a result of which the prospectus included in the Registration
Statement, as then in effect, includes an untrue statement of a material fact or
omits to state a material fact required to be stated therein or necessary to
make the statements therein, in light of the circumstances under which they were
made, not misleading, and use its best efforts promptly to prepare a supplement
or amendment to the Registration Statement or other appropriate filing with the
SEC to correct such untrue statement or omission, and deliver a number of copies
of such supplement or amendment to Investor as Investor may reasonably request;

                  (g) As promptly as practicable after becoming aware thereof,
notify Investor who holds Registrable Securities being sold (or, in the event of
an underwritten offering, the managing underwriters) of the issuance by the SEC
of a Notice of Effectiveness or any notice of effectiveness or any stop order or
other suspension of the effectiveness of the Registration Statement at the
earliest possible time;

                  (h) Notwithstanding the foregoing, if at any time or from time
to time after the date of effectiveness of the Registration Statement, the
Company notifies the Investor in writing of the existence of a Potential
Material Event, the Investor shall not offer or sell any Registrable Securities,
or engage in any other transaction involving or relating to the Registrable
Securities, from the time of the giving of notice with respect to a Potential
Material Event until such Investor receives written notice from the Company that
such Potential Material Event either has been disclosed to the public or no
longer constitutes a Potential Material Event; PROVIDED, HOWEVER, that the
Company may not so suspend the right to such holders of Registrable Securities
during the periods the Registration Statement is required to be in effect other
than during a Permitted Suspension Period. The term "Permitted Suspension

                                       4
<PAGE>

Period" means up to two suspension periods during any consecutive 12-month
period, each of which suspension period shall not either (i) be for more than
thirty (30) days or (ii) begin less than ten (10) business days after the last
day of the preceding suspension (whether or not such last day was during or
after a Permitted Suspension Period); provided further that the Company shall,
if lawful to do so, provide the Investor with at least two (2) business days'
notice of the existence (but not the substance of) a Potential Material Event;

                  (i) Use its reasonable efforts to secure and maintain the
designation of all the Registrable Securities covered by the Registration
Statement on the "Over the Counter Bulletin Board Market" of the National
Association of Securities Dealers Automated Quotations System within the meaning
of Rule 11Aa2-1 of the SEC under the Securities Exchange Act of 1934, as amended
(the "Exchange Act"), and the quotation of the Registrable Securities on The
Over the Counter Bulletin Board Market; and, without limiting the generality of
the foregoing, to arrange for at least two market makers to register with the
National Association of Securities Dealers, Inc. ("NASD") as such with respect
to such Registrable Securities;

                  (j) Provide a transfer agent and registrar, which may be a
single entity, for the Registrable Securities not later than the effective date
of the Registration Statement;

                  (k) Cooperate with the Investor who holds Registrable
Securities being offered to facilitate the timely preparation and delivery of
certificates for the Registrable Securities to be offered pursuant to the
Registration Statement and enable such certificates for the Registrable
Securities to be in such denominations or amounts as the case may be, as the
Investor may reasonably request, and, within three (3) business days after a
Registration Statement which includes Registrable Securities is ordered
effective by the SEC, the Company shall deliver, and shall cause legal counsel
selected by the Company to deliver, to the transfer agent for the Registrable
Securities (with copies to the Investor whose Registrable Securities are
included in such Registration Statement) an appropriate instruction and opinion
of such counsel; and

                  (l) Take all other reasonable actions necessary to expedite
and facilitate disposition by the Investor of the Registrable Securities
pursuant to the Registration Statement.

         4. OBLIGATIONS OF THE INVESTOR. In connection with the registration of
the Registrable Securities, the Investor shall have the following obligations:

                  (a) It shall be a condition precedent to the obligations of
the Company to complete the registration pursuant to this Agreement with respect
to the Registrable Securities of a particular Investor that such Investor shall
furnish to the Company such information regarding itself, the Registrable
Securities held by it, and the intended method of disposition of the Registrable
Securities held by it, as shall be reasonably required to effect the
registration of such Registrable Securities and shall execute such documents in
connection with such registration as the Company may reasonably request. At
least ten (10) days prior to the first anticipated filing date of the
Registration Statement, the Company shall notify Investor of the information the
Company requires from each such Investor (the "Requested Information") if such
Investor elects to have any of such Investor's Registrable Securities included
in the Registration Statement. If at least two (2) business days prior to the
filing date the Company has not received the Requested Information from an
Investor (a "Non-Responsive Investor"), then the Company may file the
Registration Statement without including Registrable Securities of such
Non-Responsive Investor;

                  (b) Investor, by such Investor's acceptance of the Registrable
Securities, agrees to cooperate with the Company as reasonably requested by the
Company in connection with the preparation and filing of the Registration
Statement hereunder, unless such Investor has notified the Company in writing of
such Investor's election to exclude all of such Investor's Registrable
Securities from the Registration Statement; and

                                       5
<PAGE>

                  (c) Investor agrees that, upon receipt of any notice from the
Company of the happening of any event of the kind described in Section 3(e) or
3(f), above, such Investor will immediately discontinue disposition of
Registrable Securities pursuant to the Registration Statement covering such
Registrable Securities until such Investor's receipt of the copies of the
supplemented or amended prospectus contemplated by Section 3(e) or 3(f) and, if
so directed by the Company, such Investor shall deliver to the Company (at the
expense of the Company) or destroy (and deliver to the Company a certificate of
destruction) all copies in such Investor's possession, of the prospectus
covering such Registrable Securities current at the time of receipt of such
notice.

         5. EXPENSES OF REGISTRATION. All reasonable expenses (other than
underwriting discounts and commissions of the Investor) incurred in connection
with registrations, filings or qualifications pursuant to Section 3, but
including, without limitation, all registration, listing, and qualifications
fees, printers and accounting fees, the fees and disbursements of counsel for
the Company shall be borne by the Company.

         6. INDEMNIFICATION. In the event any Registrable Securities are
included in a Registration Statement under this Agreement:

                  (a) To the extent permitted by law, the Company will indemnify
and hold harmless Investor who holds such Registrable Securities, the directors,
if any, of such Investor, the officers, if any, of such Investor, each person,
if any, who controls any Investor within the meaning of the Securities Act or
the Securities Exchange Act of 1934, as amended (the "Exchange Act")Exchange Act
(each, an "Indemnified Person" or "Indemnified Party"), against any losses,
claims, damages, liabilities or expenses (joint or several) incurred
(collectively, "Claims") to which any of them may become subject under the
Securities Act, the Exchange Act or otherwise, insofar as such Claims (or
actions or proceedings, whether commenced or threatened, in respect thereof)
arise out of or are based upon any of the following statements, omissions or
violations in the Registration Statement, or any post-effective amendment
thereof, or any prospectus included therein: (i) any untrue statement or alleged
untrue statement of a material fact contained in the Registration Statement or
any post-effective amendment thereof or the omission or alleged omission to
state therein a material fact required to be stated therein or necessary to make
the statements therein not misleading, (ii) any untrue statement or alleged
untrue statement of a material fact contained in the final prospectus (as
amended or supplemented, if the Company files any amendment thereof or
supplement thereto with the SEC) or the omission or alleged omission to state
therein any material fact necessary to make the statements made therein, in
light of the circumstances under which the statements therein were made, not
misleading or (iii) any violation or alleged violation by the Company of the
Securities Act, the Exchange Act, any state securities law or any rule or
regulation under the Securities Act, the Exchange Act or any state securities
law (the matters in the foregoing clauses (i) through (iii) being, collectively,
"Violations"). Subject to clause (b) of this Section 6, the Company shall
reimburse the Investor, promptly as such expenses are incurred and are due and
payable, for any legal fees or other reasonable expenses incurred by them in
connection with investigating or defending any such Claim. Notwithstanding
anything to the contrary contained herein, the indemnification agreement
contained in this Section 6(a) shall not (I) apply to a Claim arising out of or
based upon a Violation which occurs in reliance upon and in conformity with
information furnished in writing to the Company by or on behalf of any
Indemnified Person expressly for use in connection with the preparation of the
Registration Statement or any such amendment thereof or supplement thereto,
after such prospectus was made available by the Company pursuant to Section 3(c)
hereof; (II) be available to the extent such Claim is based on a failure of the
Investor to deliver or cause to be delivered the prospectus made available by
the Company or the amendment or supplement thereto made available by the
Company; (III) be available to the extent such Claim is based on the delivery of
a prospectus by the Investor after receiving notice from the Company under
Section 3(e), (f) or (g) hereof (other than a notice regarding the effectiveness
of the Registration Statement or any amendment or supplement thereto), or (IV)

                                       6
<PAGE>

apply to amounts paid in settlement of any Claim if such settlement is effected
without the prior written consent of the Company, which consent shall not be
unreasonably withheld or delayed. Investor will indemnify the Company and its
officers, directors and agents (each, an "Indemnified Person" or "Indemnified
Party") against any claims arising out of or based upon a Violation which occurs
in reliance upon and in conformity with information furnished in writing to the
Company, by or on behalf of such Investor, expressly for use in connection with
the preparation of the Registration Statement or the amendment or supplement
thereto, subject to such limitations and conditions as are applicable to the
Indemnification provided by the Company to this Section 6. Such indemnity shall
remain in full force and effect regardless of any investigation made by or on
behalf of the Indemnified Person.

                  (b) Promptly after receipt by an Indemnified Person or
Indemnified Party under this Section 6 of notice of the commencement of any
action (including any governmental action), such Indemnified Person or
Indemnified Party shall, if a Claim in respect thereof is to be made against any
indemnifying party under this Section 6, deliver to the indemnifying party a
written notice of the commencement thereof and the indemnifying party shall have
the right to participate in, and, to the extent the indemnifying party so
desires, jointly with any other indemnifying party similarly noticed, to assume
control of the defense thereof with counsel mutually satisfactory to the
indemnifying party and the Indemnified Person or the Indemnified Party, as the
case may be. In case any such action is brought against any Indemnified Person
or Indemnified Party, and it notifies the indemnifying party of the commencement
thereof, the indemnifying party will be entitled to participate in, and, to the
extent that it may wish, jointly with any other indemnifying party similarly
notified, assume the defense thereof, subject to the provisions herein stated
and after notice from the indemnifying party to such Indemnified Person or
Indemnified Party of its election so to assume the defense thereof, the
indemnifying party will not be liable to such Indemnified Person or Indemnified
Party under this Section 6 for any legal or other reasonable out-of-pocket
expenses subsequently incurred by such Indemnified Person or Indemnified Party
in connection with the defense thereof other than reasonable costs of
investigation, unless the indemnifying party shall not pursue the action of its
final conclusion. The Indemnified Person or Indemnified Party shall have the
right to employ separate counsel in any such action and to participate in the
defense thereof, but the fees and reasonable out-of-pocket expenses of such
counsel shall not be at the expense of the indemnifying party if the
indemnifying party has assumed the defense of the action with counsel reasonably
satisfactory to the Indemnified Person or Indemnified Party provided such
counsel is of the opinion that all defenses available to the Indemnified Party
can be maintained without prejudicing the rights of the indemnifying party. The
failure to deliver written notice to the indemnifying party within a reasonable
time of the commencement of any such action shall not relieve such indemnifying
party of any liability to the Indemnified Person or Indemnified Party under this
Section 6, except to the extent that the indemnifying party is prejudiced in its
ability to defend such action. The indemnification required by this Section 6
shall be made by periodic payments of the amount thereof during the course of
the investigation or defense, as such expense, loss, damage or liability is
incurred and is due and payable.

         7. CONTRIBUTION. To the extent any indemnification by an indemnifying
party is prohibited or limited by law, the indemnifying party agrees to make the
maximum contribution with respect to any amounts for which it would otherwise be
liable under Section 6 to the fullest extent permitted by law; PROVIDED,
HOWEVER, that (a) no contribution shall be made under circumstances where the
maker would not have been liable for indemnification under the fault standards
set forth in Section 6; (b) no seller of Registrable Securities guilty of
fraudulent misrepresentation (within the meaning of Section 11(f) of the
Securities Act) shall be entitled to contribution from any seller of Registrable
Securities who was not guilty of such fraudulent misrepresentation; and (c)
except where the seller has committed fraud (other than a fraud by reason of the

                                       7
<PAGE>

information included or omitted from the Registration Statement as to which the
Company has not given notice as contemplated under Section 3 hereof) or
intentional misconduct, contribution by any seller of Registrable Securities
shall be limited in amount to the net amount of proceeds received by such seller
from the sale of such Registrable Securities.

         8. SEC REPORTS. With a view to making available to the Investor the
benefits of Rule 144 promulgated under the Securities Act or any other similar
rule or regulation of the SEC that may at any time permit the Investor to sell
securities of the Company to the public without registration ("Rule 144"), the
Company agrees to:

                  (a) make and keep public information available, as those terms
are understood and defined in Rule 144;

                  (b) file with the SEC in a timely manner all reports and other
documents required of the Company under the Securities Act and the Exchange Act;
and

                  (c) furnish to Investor so long as Investor owns Registrable
Securities, promptly upon request, (i) a written statement by the Company that
it has complied with the reporting requirements of Rule 144, the Securities Act
and the Exchange Act, (ii) a copy of the most recent annual or quarterly report
of the Company and such other reports and documents so filed by the Company and
(iii) such other information as may be reasonably requested to permit the
Investor to sell such securities pursuant to Rule 144 without registration.

         9. AMENDMENT OF REGISTRATION RIGHTS. Any provision of this Agreement
may be amended and the observance thereof may be waived (either generally or in
a particular instance and either retroactively or prospectively), only with the
written consent of the Company and Investor. Any amendment or waiver effected in
accordance with this Section 10 shall be binding upon the Investor and the
Company.

         10. MISCELLANEOUS.

                  (a) A person or entity is deemed to be a holder of Registrable
Securities whenever such person or entity owns of record such Registrable
Securities. If the Company receives conflicting instructions, notices or
elections from two or more persons or entities with respect to the same
Registrable Securities, the Company shall act upon the basis of instructions,
notice or election received from the registered owner of such Registrable
Securities.

                  (b) Notices required or permitted to be given hereunder shall
be given in the manner contemplated by the Agreement, (i) if to the Company or
to the Investor, to their respective address contemplated by the Agreement, and
(iii) if to any other Investor, at such address as such Investor shall have
provided in writing to the Company, or at such other address as each such party
furnishes by notice given in accordance with this Section 10(b).

                  (c) Failure of any party to exercise any right or remedy under
this Agreement or otherwise, or delay by a party in exercising such right or
remedy, shall not operate as a waiver thereof.

                  (d) This Agreement shall be governed by and interpreted in
accordance with the laws of the State of New York for contracts to be wholly
performed in such state and without giving effect to the principles thereof
regarding the conflict of laws. Each of the parties consents to the jurisdiction

                                       8
<PAGE>

of the federal courts whose districts encompass any part of the City of New York
or the state courts of the State of New York sitting in the City of New York in
connection with any dispute arising under this Agreement and hereby waives, to
the maximum extent permitted by law, any objection, including any objection
based on FORUM NON COVENIENS, to the bringing of any such proceeding in such
jurisdictions. To the extent determined by such court, the Company shall
reimburse the Buyer for any reasonable legal fees and disbursements incurred by
the Buyer in enforcement of or protection of any of its rights under this
Agreement.

                  (e) If any provision of this Agreement shall be invalid or
unenforceable in any jurisdiction, such invalidity or unenforceability shall not
affect the validity or enforceability of the remainder of this Agreement or the
validity or enforceability of this Agreement in any other jurisdiction.

                  (f) This Agreement shall inure to the benefit of and be
binding upon the successors and assigns of each of the parties hereto.

                  (g) All pronouns and any variations thereof refer to the
masculine, feminine or neuter, singular or plural, as the context may require.

                  (h) The headings in this Agreement are for convenience of
reference only and shall not limit or otherwise affect the meaning thereof.

                  (i) This Agreement may be executed in one or more
counterparts, each of which shall be deemed an original but all of which shall
constitute one and the same agreement. This Agreement, once executed by a party,
may be delivered to the other party hereto by telephone line facsimile
transmission of a copy of this Agreement bearing the signature of the party so
delivering this Agreement.

                  (j) The Company acknowledges that any failure by the Company
to perform its obligations under Section 3(a) hereof, or any delay in such
performance could result in loss to the Investor, and the Company agrees that,
in addition to any other liability the Company may have by reason of such
failure or delay, the Company shall be liable for all direct damages caused by
any such failure or delay, unless the same is the result of force majeure.
Neither party shall be liable for consequential damages.

                  (k) This Agreement constitutes the entire agreement among the
parties hereto with respect to the subject matter hereof. There are no
restrictions, promises, warranties or undertakings, other than those set forth
or referred to herein. This Agreement supersedes all prior agreements and
understandings among the parties hereto with respect to the subject matter
hereof. This Agreement may be amended only by an instrument in writing signed by
the party to be charged with enforcement thereof.

         after the date of such Permitted Acquisition (and, notwithstanding the

         Upon the terms and subject to the conditions set forth in this
Agreement, (i) the Lenders hereby grant to the Borrower a revolving credit
facility pursuant to which each Lender severally agrees to make Revolving Credit
Loans in accordance with the following terms and conditions of this Article II,
(ii) the Swingline Lender agrees to make Swingline Loans in accordance with the

         The aggregate principal amount of all outstanding Revolving Credit
Loans plus the aggregate principal amount of all outstanding Swingline Loans
plus the aggregate principal amount of LOC Obligations outstanding shall not

respect to each Lender individually, such Lender's pro rata share of outstanding

         2.2      USE OF PROCEEDS OF REVOLVING CREDIT LOANS.

Borrower for Permitted Acquisitions, Capital Expenditures, working capital and

         2.3      REVOLVING CREDIT NOTES.

         Each Lender's Revolving Credit Loans and the Borrower's obligations to

                                       24

         2.4      SEPARATE COMMITMENTS OF THE LENDERS.

         The Borrower acknowledges that each Lender's commitment to fund its
portion of the Revolving Credit Loans is made by each Lender severally, and
neither the Agent nor any Lender shall be liable for the failure of another
Lender to timely perform under this Agreement.

         2.5      ADVANCES OF LOANS.

         Subject to the terms and conditions of this Agreement, the Borrower may
borrow, repay and reborrow Revolving Credit Loans, provided that the outstanding
principal balance of the Revolving Credit Loans shall not at any time exceed the
respective amounts permitted under Section 2.1 above. Loans shall be disbursed
as follows:

                  2.5.1 Advanced Pursuant to Borrowing Notices.

                           2.5.1(a) Applicability. Revolving Credit Loans may
                  consist of LIBOR Loans, Base Rate Loans, or a combination
                  thereof, and the funding thereof shall be subject to this
                  Section 2.5.1.

                           2.5.1(b) Borrowing Notices. As long as the Borrower
                  meets the conditions for funding stated in this Agreement, the
                  Borrower may submit requests for Revolving Credit Loans
                  ("Borrowing Notices") to the Agent. All requests shall be made
                  in writing or by telephone, subject to such security
                  procedures as the Agent may require from time to time
                  (provided that all such telephonic notices shall be confirmed
                  by written Borrowing Notices within one (1) Business Day) and
                  shall specify the proposed disbursement date for the requested
                  Revolving Credit Loan; the amount of the Revolving Credit
                  Loan; the purpose of the Revolving Credit Loan (characterized
                  in accordance with Section 2.2 above); the type of Revolving
                  Credit Loan, i.e., LIBOR Loan or Base Rate Loan; and if a
                  LIBOR Loan, the designated Interest Period. Each Borrowing
                  Notice shall irrevocably obligate the Borrower to accept the
                  Loan requested thereby. Borrowing Notices shall be in the form
                  of Exhibit 2.5.l(b) hereto or such other form as the Agent may
                  from time to time reasonably require.

                           2.5.1(c) Funding of Loans. The Lenders shall fund
                  their respective portions of requested Revolving Credit Loans
                  on the Banking Day (determined with a cutoff of 11:00 a.m.
                  Charlotte, North Carolina time, as provided in the definition
                  thereof) of the Agent's receipt of the Borrowing Notice, in
                  the case of Base Rate Loans, and on the third (3rd) Banking
                  Day following the Banking Day of Agent's receipt of the
                  Borrowing Notice, in the case of LIBOR Loans. All funds shall
                  be disbursed directly into an account maintained by the
                  Borrower with the Agent. The Borrower agrees that if any
                  Lender elects to fund any requested Revolving Credit Loan(s)
                  sooner after requested than is required hereunder, the Lender
                  may nevertheless use the entire response period allowed
                  hereunder upon receipt of any subsequent request, at the
                  Lender's sole option.

                           2.5.1(d) Base Rate Loan Limitations for Revolving
                  Credit Loans. Except for Revolving Loans made for the purpose
                  of reimbursing the Issuing Lender in respect of a drawing
                  under a Letter of Credit pursuant to Section 2.17.5, each
                  Revolving Credit Loan that is a Base Rate Loan shall be in the
                  minimum amount of $1,000,000.00 each and in multiples of
                  $100,000.00.

                           2.5.1(e) LIBOR Loan Limitations. Except for Revolving
                  Credit Loans made for the purpose of reimbursing the Issuing
                  Lender in respect of a drawing under a Letter of Credit
                  pursuant to Section 2.17.5, individual LIBOR Loans shall be in
                  the minimum amount of $1,000,000.00 each and shall be
                  requested in increments of $500,000.00. For purposes hereof,
                  LIBOR Loans with different Interest Periods shall be
                  considered as separate LIBOR Loans, even if they begin on the
                  same date, although borrowings, extensions and conversions
                  may, in accordance with the provisions hereof, be combined at
                  the end of existing Interest Periods to constitute a new
                  single LIBOR Loan with a single Interest Period. No more than
                  eight (8) LIBOR Loans may be outstanding hereunder at any
                  time.

                           2.5.1(f) Additional Limitation on LIBOR Interest
                  Periods. Notwithstanding anything to the contrary in this
                  Agreement, if a Default or an Event of Default shall have
                  occurred and be continuing, no additional LIBOR Loans may be
                  created.

                  2.5.2 Conversion of Loans. The Borrower shall have the right,
         on prior notice to the Agent made in writing or by telephone, subject
         to such security procedures as the Agent may require from time to time
         (provided that all such telephonic notices shall be confirmed by
         written Borrowing Notices within one (1) Business Day), which notice
         shall be given three (3) Banking Days (determined with a cutoff of
         11:00 a.m. Charlotte, North Carolina time, as provided in the
         definition thereof) prior to the date of any requested conversion, to
         convert any Base Rate Loan or LIBOR Loan into a Revolving Credit Loan
         of another type, or to continue any LIBOR Loan for another Interest
         Period, subject in each case to the following:

                           2.5.2(a) Application of Loans. Each conversion shall
                  be effected by applying the proceeds of the new LIBOR Loan
                  and/or Base Rate Loan, as the case may be, to the Revolving
                  Credit Loans (or portion thereof) being converted.

                           2.5.2(b) Notices of Conversions. Each notice pursuant
                  to this 2.5.2(b) shall be irrevocable and shall refer to this
                  Agreement and specify the identity and principal amount of the
                  particular Revolving Credit Loans that the Borrower requests
                  be converted or continued; if such notice requests conversion,
                  the date of such conversion (which shall be a Business Day);
                  and if a Revolving Credit Loan is to be converted to a LIBOR
                  Loan or a LIBOR Loan is to be continued, the Interest Period
                  with respect thereto. No LIBOR Loan shall be converted at any
                  time other than at the end of the Interest Period applicable

                                       26
<PAGE>

                  thereto, except in accordance with Section 2.11 hereof.
                  Conversion notices shall be in the form attached as Exhibit
                  2.5.1(b) hereto.

                  2.5.3 Absence of Election. In the event that the Borrower
         shall not give notice to continue any LIBOR Loan for a subsequent
         period, such LIBOR Loan (unless repaid) shall automatically be
         converted into a Base Rate Loan. If the Borrower fails to specify in
         any Borrowing Notice the type of borrowing or, in the case of a LIBOR
         Loan, the applicable Interest Period, the Borrower will be deemed to
         have requested a Base Rate Loan. If the Agent reasonably believes that
         any failure by the Borrower to specify the type of borrowing or the
         applicable Interest Period shall have resulted from failure of
         communications equipment or clerical error, then prior to funding any
         such borrowing Agent shall use reasonable efforts to obtain
         confirmation from the Borrower of the contents of such Borrowing
         Notice; provided, however, in the absence of prompt confirmation by the
         Borrower which specifies the type of borrowing and/or the applicable
         Interest Period, the Borrower will be deemed to have requested a Base
         Rate Loan. Notwithstanding anything to the contrary contained above, if
         a Default or Event of Default shall have occurred and be continuing, no
         LIBOR Loan may be continued and no Base Rate Loan may be converted into
         a LIBOR Loan.

                  2.5.4 Implied Representations Upon Request for Revolving
         Credit Loan. Upon making any request for any Loan, the Borrower shall
         be deemed to have warranted to the Agent and the Lenders that all
         conditions to funding set forth in Article III hereof are satisfied and
         that all warranties made herein are true and shall be true as of the
         funding of the requested Loan, subject to exception for warranties that
         speak to a specific date or for which the underlying facts have changed
         pursuant to transactions permitted under this Agreement.

                  2.5.5 Advance Not Waiver. Any Lender's making of any Loan that
         it is not obligated to make under any provision of Article III hereof
         or any other provision hereof shall not be construed as a waiver of
         such Lender's right to withhold future Loans, notify the Agent of an
         Event of Default, or otherwise demand strict compliance with this
         Agreement.

                  2.5.6 Draws by Debit Memorandum. The Agent may cause the
         Lenders to draw amounts that may be available under the Revolving
         Credit Loans to pay any Obligation that is not otherwise timely paid.

         2.6      INTEREST.

         Interest shall accrue on each Revolving Credit Loan as follows:

                  2.6.1 Base Rate Loans. Interest shall accrue on each Base Rate
         Loan at an annual rate equal to the Alternate Base Rate plus the
         Applicable Base Rate Margin, said rate to change contemporaneously with
         any change in the Alternate Base Rate or the Alternate Base Rate
         Margin.

                                       27
<PAGE>

                  2.6.2 LIBOR Loans. Interest shall accrue on each LIBOR Loan at
         a rate equal to the LIBO Rate for the selected Interest Period plus the
         Applicable LIBO Rate Margin, said rate to change contemporaneously with
         any change in the LIBO Rate Margin.

                  2.6.3 Calculation of Interest. Interest for both Base Rate
         Loans and LIBOR Loans shall be computed on the basis of a 360-day year
         counting the actual number of days elapsed. Interest shall accrue on
         the Business Day a Revolving Credit Loan is extended and shall accrue
         to but not including the Banking Day that payment is received by the
         Agent in immediately available funds.

                  2.6.4 Default Rate. Notwithstanding the foregoing, upon the
         occurrence of an Event of Default and during the continuation of such
         Event of Default, interest shall be charged at the Default Rate,
         regardless of whether the Lenders have elected to exercise any other
         remedies available to the Lenders, including, without limitation,
         acceleration of the maturity of the outstanding principal of the Loans.

                  2.6.5 Payment of Interest. Interest for Base Rate Loans and
         LIBOR Loans shall be due and payable in arrears, without notice, on
         each Interest Payment Date.

                  2.6.6 Usury-Savings Provision. It is the intention of the
         parties that all charges under or in connection with this Agreement and
         the Obligations, however denominated, and including (without
         limitation) all interest, commitment fees, late charges and loan
         charges, shall be limited to the Maximum Lawful Amount. Such charges
         hereunder shall be characterized and all provisions of the Loan
         Documents shall be construed as to uphold the validity of charges
         provided for therein to the fullest possible extent. Additionally, all
         charges hereunder shall be spread over the full permitted term of the
         Obligations for the purpose of determining the effective rate thereof
         to the fullest possible extent, without regard to prepayment of or the
         right to prepay the Obligations. If for any reason whatsoever, however,
         any charges paid or contracted to be paid in respect of the Obligations
         shall exceed the Maximum Lawful Amount, then, without any specific
         action by the Lenders, the Agent or the Borrower, the obligation to pay
         such interest and/or other charges shall be reduced to the Maximum
         Lawful Amount in effect from time to time, and any amounts collected by
         the Lenders that exceed the Maximum Lawful Amount shall be applied to
         the reduction of the principal balance of the Obligations and/or
         refunded to the Borrower so that at no time shall the interest or loan
         charges paid or payable in respect of the Obligations exceed the
         Maximum Lawful Amount. This provision shall control every other
         provision herein and in any and all other agreements and instruments
         now existing or hereafter arising between the Borrower and the Lenders
         with respect to the Obligations.

         2.7      ALTERNATE RATE OF INTEREST IF LIBOR UNAVAILABLE.

         In the event, and on each occasion, that on the date of commencement of
any Interest Period for a LIBOR Loan, a Lender shall have determined (i) that
dollar deposits in the amount of the requested principal amount of such LIBOR
Loan are not generally available in the London Interbank Market; (ii) that the
rate at which such dollar deposits are being offered will not

                                       28
<PAGE>

adequately and fairly reflect the cost to the Lender of making or maintaining
such LIBOR Loan during such Interest Period; or (iii) that reasonable means do
not exist for ascertaining the LIBO Rate, the Lender shall, as soon as
practicable thereafter, give written or telephonic notice of such determination
to the Borrower and the Agent. In the event of any such determination, any
request by the Borrower for a LIBOR Loan under this Agreement shall, until the
circumstances giving rise to such notice no longer exist, be deemed to be a
request for a Base Rate Loan. Each determination by a Lender hereunder shall be
conclusive absent manifest error.

         2.8      CHANGE IN CIRCUMSTANCES.

                  2.8.1 Imposition of Requirements. Notwithstanding any other
         provision herein, if after the date of this Agreement any change in
         applicable Laws or in the interpretation or administration thereof by
         any Governmental Authority charged with the interpretation or
         administration thereof (whether or not having the force of Law) shall
         change the basis of taxation of payments to a Lender under any LIBOR
         Loan made by the Lender or any other fees or amounts payable hereunder
         (other than taxes imposed on the overall net income, gross receipts or
         added value of a Lender by the country in which the Lender is located,
         or by the jurisdiction in which a Lender has its principal office, or
         by any political subdivision or taxing authority therein), or shall
         impose, modify or deem applicable any reserve requirement, special
         deposit, insurance charge (including FDIC insurance on LIBOR
         Liabilities) or similar requirement against assets of, deposits with or
         for the account of, or credit extended by, a Lender or shall impose on
         a Lender or the London Interbank Market any other condition affecting
         this Agreement or LIBOR Loans made by a Lender, and the result of any
         of the foregoing shall be to increase the cost to the Lender of making
         or maintaining its LIBOR Loan or to reduce the amount of any sum
         received or receivable by a Lender hereunder (whether of principal,
         interest or otherwise) in respect thereof by an amount deemed by the
         affected Lender to be material, then the Borrower will pay to such
         Lender such additional amount or amounts as will compensate the Lender
         for such additional costs of reduction.

                  2.8.2 Other Changes. If either (i) the introduction of, or any
         change in, or in the interpretation of, any United States or foreign
         Law; or (ii) compliance with any directive, guidelines or request from
         any central bank or other United States or foreign Governmental
         Authority (whether or not having the force of law) promulgated or made
         after the date hereof, affects or would affect the amount of capital
         required or expected to be maintained by a Lender (or any lending
         office of a Lender) or any corporation directly or indirectly owning or
         controlling a Lender (or any lending office of a Lender) based upon the
         existence of this Agreement, and the Lender shall have determined that
         such introduction, change or compliance has or would have the effect of
         reducing the rate of return on the Lender's capital or on the capital
         of such owning or controlling corporation as a consequence of its
         obligations hereunder (including its commitment) to a level below that
         which the Lender or such owning or controlling corporation could have
         achieved but for such introduction, change or compliance (after taking
         into account that Lender's policies or the policies of such owning or
         controlling corporation, as the case may be, regarding capital
         adequacy) by an amount deemed by the Lender (in its sole discretion) to
         be material, then, from time to time, the Borrower shall pay to the
         Lender such additional

                                       29
<PAGE>

         amount or amounts as will compensate the Lender for such reduction
         attributable to making, funding and maintaining its commitment and
         Loans hereunder.

                  2.8.3 Computation of Amounts. A certificate of a Lender
         setting forth the basis and method of computation of such amount or
         amounts specified in Sections 2.8.1 and 2.8.2 hereof as shall be
         necessary to compensate the Lender (or its participating banks) as
         specified above, as the case may be, shall be delivered to the Borrower
         and shall be conclusive absent manifest error; provided however, that
         the Borrower shall be responsible for compliance herewith and the
         payment of increased costs only to the extent that (i) any change in
         Laws giving rise to increased costs occurs after the date of this
         Agreement; (ii) such increased costs are imposed by the Lender on all
         other borrowers similarly situated with the Borrower; and (iii) the
         Lender gives notice of the change giving rise to increased costs within
         ninety (90) Business Days after the Lender has, or with reasonable
         diligence should have had, knowledge of the change, or else the Lender
         can only collect costs from and after the date of the notice. Subject
         to the foregoing, the Borrower shall pay the affected Lender the amount
         shown as due on any such certificate within ten (10) Business Days
         after its receipt of such certificate.

                  2.8.4 No Duty to Contest. The protection of this Section 2.8
         shall be available to a Lender regardless of any possible contention of
         invalidity or inapplicability of the Law or condition that shall have
         been imposed. Should a Lender assess any charge to the Borrower under
         this Section 2.8, and provided that the Borrower pays the assessment to
         the affected Lender, the Borrower may within ninety (90) days after
         receiving notice of such assessment undertake, at the Borrower's own
         expense, any contest of the matters giving rise to the charge that may,
         in the opinion of the Borrower's independent counsel issued to the
         affected Lender, and concurred in by counsel to the Lender, have a
         reasonable chance of success, provided further that the contest would
         not require the assertion of any position contrary to a position taken
         by the Lender generally with taxing or regulatory authorities or any
         other involved parties and that there does not exist any other
         circumstance that would disadvantage the Lender in the event of such
         contest, as the affected Lender may determine in its discretion. The
         affected Lender shall offer reasonable participation to the Borrower
         for the purpose of enabling the Borrower to pursue the contest of such
         issue, with all expenses, including fees and expenses of the affected
         Lender's counsel, to be paid by the Borrower.

         2.9      CHANGE IN LEGALITY OF LIBOR LOANS.

         Notwithstanding anything to the contrary herein contained, if any
change in any Law or in interpretation thereof by any Governmental Authority
charged with the administration or interpretation thereof shall make it unlawful
for a Lender to make or maintain any LIBOR Loan or to give effect to its
obligations as contemplated hereby, then, by written notice to the Borrower, the
Lender may (i) declare that LIBOR Loans will not thereafter be made by the
Lender hereunder, whereupon the Borrower shall be prohibited from requesting
LIBOR Loans from the Lender hereunder unless such declaration is subsequently
withdrawn; and (ii) require that all outstanding LIBOR Loans made by it be
converted to Base Rate Loans, in which event (a) all such LIBOR Loans shall be
automatically converted to Base Rate Loans (but without

                                       30
<PAGE>

imposition of any additional breakage fee or other charge that would normally
become due under Section 2.11 hereof) as of the effective date of such notice,
and (b) all payments and prepayments of principal that would otherwise have been
applied to repay the converted LIBOR Loans shall instead be applied to repay the
Base Rate Loans resulting from the conversion of such LIBOR Loans. Under such
circumstances, a borrowing request for a LIBOR Loan shall be regarded, as to the
Lender who has given notice under this Section 2.9, a request for a Base Rate
Loan, and as to all other Lenders, it shall be regarded as a request for a LIBOR
Loan. For purposes of this Section 2.9, a notice to the Borrower by the Lender
pursuant to (a) above shall be effective, if lawful, on the last day of the then
current Interest Period; in all other cases, such notice shall be effective on
the date of receipt by the Borrower.

         2.10     PRINCIPAL REPAYMENT.

         The principal amount of all Revolving Credit Loans shall become due and
payable in full on the Maturity Date or the earlier acceleration of the
Revolving Credit Loans in accordance with the terms of this Agreement.

         2.11     PREPAYMENT OF LIBOR LOANS.

                  2.11.1 Notice of LIBOR Loan Prepayment. The Borrower may, upon
         three (3) Banking Days' prior written notice to the Agent (with a
         Banking Day cutoff of 11:00 a.m. Charlotte, North Carolina time, as
         provided in the definition thereof), and upon payment of all applicable
         premiums set forth in Section 2.11.3 hereof, prepay any outstanding
         LIBOR Loans prior to any Interest Payment Date for such LIBOR Loans, in
         whole or in part. Each notice of prepayment of any LIBOR Loan shall
         specify the date and amount of such prepayment and shall be
         irrevocable.

                  2.11.2 Amount of LIBOR Loan Prepayment. Each partial
         prepayment of any LIBOR Loan shall be in an aggregate principal amount
         which is the lesser of (i) the then outstanding principal balance of
         the one or more LIBOR Loans to be prepaid, or (ii) $1,000,000.00 or a
         larger integral multiple of $100,000.00. Interest on the amount prepaid
         accrued to the prepayment date shall be paid on such date.

                  2.11.3 LIBOR Loan Breakage Costs. The Borrower shall
         indemnify, defend and hold harmless each Lender against any loss or
         expense that a Lender may incur in connection with the prepayment of a
         LIBOR Loan, the Borrower's failure to borrow or to pay when it stated
         it would do so, including, but not limited to, the fees or charges
         customarily included in "breakage costs" that may result to a Lender
         from the early repayment of a LIBOR Liability, which costs may be
         calculated by a Lender as though the Loan(s) retired by the Borrower's
         prepayment had been match-funded with a corresponding LIBOR Liability,
         whether or not the Lender manages its LIBOR Liabilities on a
         loan-by-loan basis. Additionally, upon prepayment of any LIBOR Loan on
         a date other than the relevant Interest Payment Date for such
         borrowing, the Borrower shall pay to the Lenders, in addition to all
         other payments then due and owing the Lenders, premiums which shall be
         equal to an amount, if any, reasonably determined by the Agent to be
         the difference between the rate of interest then applicable to the
         relevant

                                       31
<PAGE>

         LIBOR Loan and the yield the Lenders would receive upon reinvestment of
         so much of the relevant LIBOR Loans as is prepaid for the remainder of
         the term of the relevant LIBOR Loan or Loans- Anything in this Section
         2.11.3 to the contrary notwithstanding, the premiums payable upon any
         such prepayment shall not exceed the amount, if any, determined by the
         Agent to be the difference between the rate of interest then applicable
         to the relevant LIBOR Loan and the yield that the Lenders could receive
         upon reinvestment in the "Floor Reinvestment" of so much of the
         relevant LIBOR Loan as is prepaid for the remainder of tile term of the
         relevant LIBOR Loan. For purposes hereof, "Floor Reinvestment" shall
         mean an investment for the time period from the date of such prepayment
         to the end of the relevant Interest Period applicable to such LIBOR
         Loan at an interest rate per annum equal to the Federal Funds Rate on
         the date of such prepayment. All determinations, estimates,
         assumptions, allocations and the like required for the determination of
         such premiums shall be made by the Agent in good faith and shall be
         presumed correct absent manifest error.

         2.12     PREPAYMENT OF BASE RATE LOANS.

         The Borrower may at any time prepay any outstanding Base Rate Loans
prior to the Maturity Date in whole or in part without premium or penalty upon
at least one Business Day's prior notice to the Agent. All such prepayments
shall be made in minimum amounts of $500,000.00 and in increments of $100,000.00
each.

         2.13     MANDATORY PREPAYMENTS.

                  2.13.1 Commitments.

                  2.13.1(a) Total Commitments. If at any time, the sum of the
         aggregate principal amount of outstanding Revolving Credit Loans plus
         LOC Obligations plus Swingline Loans outstanding shall exceed the
         aggregate amount of the Total Commitments, the Borrower immediately
         shall prepay the Revolving Credit Loans and/or Swingline Loans (and
         after all Loans have been repaid) cash collateralize the LOC
         Obligations, in an amount sufficient to eliminate such excess.

                  2.13.1(b) Swingline Commitment. If at any time, the sum of the
         aggregate principal amount of Swingline Loans shall exceed the
         Swingline Commitment, the Borrower immediately shall prepay the
         Swingline Loans in an amount necessary to eliminate such excess.

                  2.13.1(c) LOC Committed Amount. If at any time, the sum of the
         aggregate principal amount of all LOC Obligations shall exceed the LOC
         Committed Amount, the Borrower shall immediately cash collateralize the
         LOC Obligations in an amount sufficient to eliminate such excess.

                  2.13.2 Asset Dispositions. Promptly (and in any event within 5
         Business Days) after the occurrence of any Asset Disposition, the
         Borrower shall prepay the Loans and the 364-Day Loans (on a pro rata
         basis) in an aggregate amount equal to one hundred

                                       32
<PAGE>

         percent (100%) of the Net Proceeds of the related Asset Disposition
         (such prepayment to be applied as set forth in Section 2.13.5 below).
         Notwithstanding the terms of Section 2.13.5 below, in the event the
         Required Lenders consent to an Asset Disposition that would otherwise
         be prohibited by the terms of this Agreement, the Lenders agree that
         any Net Proceeds from such Asset Disposition remaining after having
         prepaid the Loans (as set forth in Section 2.13.5 below) will not be
         required to be placed in a cash collateral account to secure the LOC
         Obligations.

                  2.13.3 Issuances of Equity. Promptly (and in any event within
         5 Business Days) after the receipt by any Credit Party of proceeds from
         any Equity Issuance (other than (a) equity issued by the Borrower to
         (i) employees, officers and directors of any Borrower Entity and (ii)
         those consultants of any Borrower Entity holding options to purchase
         Capital Stock of the Borrower as of the Closing Date and (b) equity
         issued by a Credit Party as consideration for a Permitted Acquisition),
         the Borrower shall prepay the Loans and the 364-Day Loans (on a pro
         rata basis) in an aggregate amount equal to 100% of the Net Proceeds of
         such Equity Issuance (such prepayment to be applied as set forth in
         Section 2.13.5 below).

                  2.13.4 Debt Issuances. Immediately upon receipt by any
         Borrower Entity of proceeds from any Debt Issuance, the Borrower shall
         prepay the Loans and the 364-Day Loans (on a pro rata basis) in an
         aggregate amount equal to 100% of the Net Proceeds of such Debt
         Issuance to the Lenders (such prepayment to be applied as set forth in
         Section 2.13.5 below). Notwithstanding the terms of Section 2.13.5
         below, in the event the Required Lenders consent to a Debt Issuance
         that would otherwise be prohibited by the terms of this Agreement, the
         Lenders agree that any Net Proceeds from such Debt Issuance remaining
         after having prepaid the Loans (as set forth in Section 2.13.5 below)
         will not be required to be placed in a cash collateral account to
         secure the LOC Obligations.

                  2.13.5 Application of Mandatory Prepayments. All amounts
         required to be paid pursuant to this Section 2.13 shall be applied as
         follows: (a) with respect to all amounts prepaid pursuant to Section
         2.13.1(a), to Revolving Credit Loans and (after all Revolving Credit
         Loans have been repaid), to Swingline Loans and (after all Swingline
         Loans have been repaid), to a cash collateral account in respect of LOC
         Obligations, (b) with respect to all amounts prepaid pursuant to
         Section 2.13.1(b), to Swingline Loans, (c) with respect to all amounts
         prepaid pursuant to Section 2.13.1(c), to a cash collateral account in
         respect of LOC Obligations, (d) with respect to all amounts prepaid
         pursuant to Sections 2.13.2 and 2.13.4, pro rata to the Loans (with a
         corresponding reduction in the Total Commitments) and the 364-Day Loans
         and (e) with respect to all amounts prepaid pursuant to Section 2.13.3,
         pro rata to the Loans and the 364-Day Loans. All prepayments made to
         the Loans pursuant to Sections 2.13.2, 2.13.3 and 2.13.4 shall be
         applied first to the Revolving Credit Loans until paid in full and then
         to the Swingline Loans and (after all Loans have been repaid) to a cash
         collateral account in respect of LOC Obligations (with a corresponding
         reduction in the Total Commitments with respect to any prepayment
         pursuant to Sections 2.13.2 or 2.13.4) until paid in full; provided,
         that, with respect to any prepayment pursuant to Section 2.13.3, so
         long as no Default or Event

                                       33
<PAGE>

         of Default exists, the Borrower shall not be required to cash
         collateralize the LOC Obligations outstanding as of the date of such
         prepayment provided that the Total Commitments as of the date of such
         prepayment exceed the amount of such LOC Obligations outstanding.
         Within the parameters of the application set forth above, prepayments
         shall be applied first to Base Rate Loans and then to LIBOR Loans in
         direct order of Interest Period maturities. All prepayments under this
         Section 2.13 shall be subject to Section 2.11.3 and accompanied by
         interest on the principal amount prepaid through the date of
         prepayment.

         2.14     REDUCTION OF COMMITMENT.

                  2.14.1 Voluntary Reduction. The Borrower shall have the right
         permanently to reduce the amount of the Total Commitments, at any time
         and from time to time, in any amount of at least $5,000,000.00 and in
         an integral multiple of $1,000,000.00, which reduction shall reduce
         each Lender's Commitment on a Pro Rata basis; provided, that, no such
         termination or reduction shall be made which would cause the sum of the
         aggregate principal amount of outstanding Revolving Credit Loans plus
         the aggregate principal amount of outstanding Swingline Loans plus the
         aggregate amount of LOC Obligations outstanding to exceed the aggregate
         amount of the Total Commitments. Any reduction by the Borrower shall
         take effect on a date specified in a written notice to the Agent that
         is at least ten (10) Business Days after the date the Agent receives
         such notice. Upon any reduction, the Borrower shall immediately pay the
         Agent any breakage costs or other such charges due under other
         provisions of this Agreement as a result of the early payment of any
         LIBOR Loan in connection with the reduction of the Total Commitments.
         Following such reduction, the nonusage fee provided for in Section
         2.15.1 shall be calculated with respect to the Total Commitments as so
         reduced from the effective date of the reduction.

                  2.14.2 Mandatory Reductions. The Total Commitments
         automatically shall be permanently reduced from time to time in
         accordance with the terms of Section 2.13.

                  2.14.3 Maturity Date. Unless terminated sooner pursuant to
         Section 2.14.1 or Section 8.2.2, the Commitments of the Lenders and the
         LOC Commitment of the Issuing Lender shall automatically terminate on
         the Maturity Date.

         2.15     FEES.

                  2.15.1 Commitment Fee. The Borrower shall pay to the Agent for
         distribution to the Lenders Pro Rata an additional commitment fee on
         the Unused Revolving Commitments, such fee to accrue beginning on the
         date that Agent confirms in writing that all conditions to the initial
         advance provided under Section 3.1 of this Agreement have been
         satisfied or waived. This fee shall be determined by applying the
         Applicable Commitment Fee (applied on the basis of a 360-day year) to
         the Unused Revolving Commitments (advances under the Swingline
         Commitment shall not be regarded as "used" for the purpose of
         determining usage of the Revolving Credit Loans). The

                                       34
<PAGE>

         commitment fee shall be paid in arrears on each Interest Payment Date
         applicable to Base Rate Loans. This commitment fee is not refundable.

                  2.15.2 Letter of Credit Fee. In consideration of the issuance
         of standby Letters of Credit hereunder, the Borrower promises to pay to
         the Agent for distribution to the Lenders Pro Rata a fee (the "Letter
         of Credit Fee") with respect to the Letters of Credit. The fee shall be
         determined by applying the Applicable Letter of Credit Fee (applied on
         the basis of a 360-day year) to the average daily maximum amount
         available to be drawn under each such standby Letter of Credit computed
         at a per annum rate for each day from the date of issuance to the date
         of expiration (other than the Existing Letter of Credit, for which the
         Applicable Letter of Credit Fee shall be computed at a per annum rate
         for each day from the Closing Date to the date of expiration). The
         Letter of Credit Fee will be payable quarterly in arrears on the last
         Business Day of each March, June, September and December for the
         immediately preceding quarter (or a portion thereof).

                  2.15.3 Issuing Lender Fees. In addition to the Letter of
         Credit Fee payable pursuant to Section 2.15.2, the Borrower promises to
         pay to the Agent for the account of the Issuing Lender without sharing
         by the other Lenders (i) a letter of credit fronting fee of 1/8% on the
         average daily maximum amount available to be drawn under each Letter of
         Credit computed at a per annum rate for each day from the date of
         issuance to the date of expiration (which fronting fee shall be payable
         quarterly in arrears on the last Business Day of each March, June,
         September and December for the immediately preceding quarter (or a
         portion thereof)) and (ii) the customary charges from time to time of
         the Issuing Lender with respect to the issuance, amendment, transfer,
         administration, cancellation and conversion of, and drawings under,
         such Letters of Credit.

         2.16     SWINGLINE LOANS.

         The Swingline Lender hereby agrees to extend to the Borrower Swingline
Loans in the aggregate amount not to exceed Ten Million and No/100 Dollars
($10,000,000.00), on the following terms and conditions.

                  2.16.1 Use of Proceeds of Swingline Loans. The Borrower may
         use the proceeds of Swingline Loans for working capital purposes.

                  2.16.2 Swingline Note. The Swingline Loans shall be evidenced
         by the Swingline Note.

                  2.16.3 Funding of Swingline Loans Advanced Pursuant to
         Borrowing Notices.

                           2.16.3(a) Applicability. Except for Swingline Loans
                  made pursuant to Account Agreements as provided in Section
                  2.16.4 hereof, the funding of Swingline Loans shall be subject
                  to this Section 2.16.3.

                           2.16.3(b) Borrowing Notices. As long as the Borrower
                  meets the conditions for funding stated in this Agreement, the
                  Borrower may submit requests for Swingline Loans ("Swingline
                  Borrowing Notices") to the Swingline Lender. The Borrower
                  shall request a Swingline Loan borrowing by written notice (or
                  telephonic notice promptly confirmed in writing) to the
                  Swingline Lender (with a copy to the Agent) not later than
                  1:00 p.m. (Charlotte, North Carolina time) on the Business Day
                  of the requested borrowing. Each such request shall be
                  irrevocable and shall specify (i) that a Swingline Loan is
                  requested, (ii) the date of the requested borrowing (which
                  shall be a Business Day) and (iii) the aggregate principal
                  amount to be borrowed. Swingline Borrowing Notices shall be in
                  such form as the Swingline Lender may from time to time
                  require.

                           2.16.3(c) Funding of Swingline Loans. The Swingline
                  Lender shall initiate the transfer of funds representing the
                  Swingline Loan advance to the Borrower by 3:00 p.m.
                  (Charlotte, North Carolina time) on the Business Day of the
                  requested borrowing. All funds shall be disbursed directly
                  into an account maintained by the Borrower with the Swingline
                  Lender.

                           2.16.3(d) Minimum Amounts for Swingline Loans. Each
                  Swingline Loan shall be in a minimum amount of $250,000.00
                  each and in multiples of $50,000.00.

                  2.16.4 Funding of Swingline Loans Advanced Pursuant to Cash
         Management Accounts. The Borrower may have in effect from time to time
         separate agreements with the Swingline Lender or its affiliates
         ("Account Agreements") establishing cash management procedures that may
         involve the automatic disbursement and/or repayment of Swingline Loans.
         The Account Agreements may be established using standardized forms that
         do not address the specific circumstances of the Swingline Loan. To
         resolve potential inconsistencies between this Agreement and Account
         Agreements, the terms of this Agreement and of Account Agreements shall
         relate to one another as follows:

                           2.16.4(a) Funding and Payment Procedures Controlled
                  by Account Agreements. The Account Agreements shall control
                  this Agreement as to (i) Section 2.16.3 hereof regarding
                  funding procedures, and (ii) Interest Payment Dates, to the
                  extent that an Account Agreement may provide for such payment
                  more frequently than otherwise required under this Agreement.

                           2.16.4(b) Certain Provisions Controlled by this
                  Agreement. Notwithstanding any provision of an Account
                  Agreement to the contrary, except as provided above in Section
                  2.16.4(a) hereof, the provisions of this Agreement shall
                  control any Account Agreement to the extent that an Account
                  Agreement may be inconsistent with this Agreement.

                           2.16.4(c) Continuing Warranty Under Account
                  Agreements. Because Account Agreements may provide for the
                  making of Swingline Loans

                                       36
<PAGE>

                  without formal draw requests from the Borrower, the Borrower
                  agrees that the Borrower's warranty under Section 2.16.5
                  hereof as to the satisfaction of all conditions to the right
                  to receive Swingline Loans shall be a continuing one during
                  any period that such an Account Agreement may be in effect.
                  Therefore, any Swingline Loans funded by the Swingline Lender
                  pursuant to an Account Agreement after the failure of a
                  condition stated in Article III hereof shall be deemed made
                  upon the affirmative misrepresentation of the Borrower unless
                  the Swingline Lender has received written notice of and waived
                  the failed condition in writing.

                  2.16.5 Implied Representations Upon Request for Swingline
         Loan. Upon making any request for a Swingline Loan, the Borrower shall
         be deemed to have represented to the Swingline Lender that all
         conditions to funding are satisfied as of the submission of the request
         to the Swingline Lender.

                  2.16.6 Advance Not Waiver. The Swingline Lender's making of
         any Swingline Loan that it is not obligated to make under any provision
         of Article III hereof or any other provision hereof shall not be
         construed as a waiver of the Swingline Lender's right to withhold
         future Swingline Loans, notify the Agent of an Event of Default, or
         otherwise demand strict compliance with this Agreement.

                  2.16.7 Interest. Interest shall be charged and paid on each
         Swingline Loan as follows:

                           2.16.7(a) Rate of Interest. Interest shall accrue on
                  Swingline Loans at an annual rate equal to the Adjusted Base
                  Rate plus the Applicable Base Rate Margin, said rate to change
                  contemporaneously with any change in the Adjusted Base Rate or
                  the Applicable Base Rate Margin.

                           2.16.7(b) Calculation of Interest. Interest shall be
                  computed on the basis of a 360-day year counting the actual
                  number of days elapsed.

                           2.16.7(c) Payment of Interest. Interest shall be due
                  and payable in arrears without notice on each Interest Payment
                  Date.

                           2.16.7(d) Default Rate. Notwithstanding the
                  foregoing, upon the occurrence of an Event of Default and
                  during the continuation of such Event of Default until it is
                  cured or waived, interest shall be charged at the Default
                  Rate, regardless of whether the Swingline Lender has elected
                  to exercise any other remedies available to it, including,
                  without limitation, acceleration of the maturity of the
                  outstanding principal of the Swingline Loans.

                  2.16.8 Repayment of Principal. All remaining principal,
         interest and expenses outstanding under the Swingline Loans shall
         become due in full on the Maturity Date or the earlier acceleration of
         the Revolving Credit Loans in accordance with the terms of this
         Agreement (unless required to be repaid by the Swingline Lender
         pursuant to the

                                       37
<PAGE>

         terms of Section 2.16.9 below). The Borrower may at any time prepay any
         outstanding Swingline Loans in whole or in part without premium or
         penalty.

                  2.16.9 Procedures Among the Lenders. The Borrower agrees to
         repay all Swingline Loans within one Business Day of demand therefor by
         the Swingline Lender. Each repayment of a Swingline Loan may be
         accomplished by requesting Revolving Credit Loans which request is not
         subject to the conditions set forth in Section 3.2. In the event that
         the Borrower shall fail to timely repay any Swingline Loan, and in any
         event upon (i) request by the Swingline Lender, (ii) the occurrence of
         an Event of Default described in Section 8.1.7 or (iii) the
         acceleration of any Loan or termination of any Commitment pursuant to
         Section 8.2.2, each other Lender shall irrevocably and unconditionally
         require from the Swingline Lender without recourse or warranty, an
         undivided participation interest in the outstanding Swingline Loans as
         necessary to cause each Lender to own a Pro Rata interest in the
         outstanding Swingline Loans by directly purchasing a participation in
         the outstanding Swingline Loans in such amount (regardless of whether
         the conditions precedent thereto set forth in Section 3.2 are then
         satisfied, whether or not the Borrower has submitted a Borrowing Notice
         and whether or not the Commitments are then in effect, any Event of
         Default exists or all the Loans have been accelerated) and paying the
         proceeds thereto to the Swingline Lender at the address provided in
         Section 10.1, or at such other address as the Swingline Lender may
         designate, in Dollars and in immediately available funds. If such
         amount is not in fact made available to the Swingline Lender by any
         Lender, the Swingline Lender shall be entitled to recover such amount
         on demand from such Lender, together with accrued interest thereon for
         each day from the date of demand thereof, at the Federal Funds Rate. If
         such Lender does not pay such amount forthwith upon the Swingline
         Lender's demand therefor, and until such time as such Lender makes the
         required payment, the Swingline Lender shall be deemed to continue to
         have outstanding Swingline Loans in the amount of such unpaid
         participation obligation for all purposes of the Loan Documents other
         than those provisions requiring the other Lenders to purchase a
         participation therein. Further, such Lender shall be deemed to have
         assigned any and all payments made of principal and interest on its
         Loans, and any other amounts due to it hereunder to the Swingline
         Lender to fund Swingline Loans in the amount of the participation in
         Swingline Loans that such Lender failed to purchase pursuant to this
         Section 2.16.9 until such amount has been purchased (as a result of
         such assignment or otherwise).

         2.17     LETTER OF CREDIT SUBFACILITY.

                  2.17.1 Issuance. Subject to the terms and conditions hereof
         and in reliance upon the representations and warranties set forth
         herein, the Issuing Lender agrees to issue, and each Lender severally
         agrees to participate in the issuance by the Issuing Lender of, standby
         Letters of Credit in Dollars from time to time from the Closing Date
         until the date thirty (30) days prior to the Maturity Date as the
         Borrower may request, in a form acceptable to the Issuing Lender;
         provided, however, that (i) the LOC Obligations outstanding shall not
         at any time exceed TWENTY MILLION DOLLARS ($20,000,000) (the "LOC
         Committed Amount"). No Letter of Credit shall (x) have an original
         expiry date more than one year from the date of issuance or (y) as
         originally issued or as extended, have an expiry date

                                       38
<PAGE>

         extendingbeyond the date thirty (30) days prior to the Maturity Date.
         Each Letter of Credit shall comply with the related LOC Documents. The
         issuance and expiry dates of each Letter of Credit shall be a Business
         Day.

                  2.17.2 Notice and Reports. The request for the issuance of a
         Letter of Credit shall be submitted by the Borrower to the Issuing
         Lender at least three (3) Business Days prior to the requested date of
         issuance. The Issuing Lender will, at least quarterly and more
         frequently upon request, disseminate to each of the Lenders a detailed
         report specifying the Letters of Credit which are then issued and
         outstanding and any activity with respect thereto which may have
         occurred since the date of the prior report, and including therein,
         among other things, the beneficiary, the face amount and the expiry
         date, as well as any payment or expirations which may have occurred.

                  2.17.3 Participation.

                           (i) Each Lender acknowledges and confirms that it has
                  a Participation Interest in the liability of the Issuing
                  Lender under each Existing Letter of Credit in an amount equal
                  to its Commitment Percentage of such Existing Letters of
                  Credit. The Borrower's reimbursement obligations in respect of
                  each Existing Letter of Credit, and each Lender's obligations
                  in connection therewith, shall be governed by the terms of
                  this Agreement.

                           (ii) Each Lender, upon issuance of a Letter of
                  Credit, shall be deemed to have purchased without recourse a
                  Participation Interest from the Issuing Lender in such Letter
                  of Credit and the obligations arising thereunder and any
                  collateral relating thereto, in each case in an amount equal
                  to its pro rata share of the obligations under such Letter of
                  Credit (based on the respective Commitment Percentages of the
                  Lenders) and shall absolutely, unconditionally and irrevocably
                  assume and be obligated to pay to the Issuing Lender and
                  discharge when due, its pro rata share of the obligations
                  arising under such Letter of Credit. Without limiting the
                  scope and nature of each Lender's Participation Interest in
                  any Letter of Credit, to the extent that the Issuing Lender
                  has not been reimbursed as required hereunder or under any
                  such Letter of Credit, each such Lender shall pay to the
                  Issuing Lender its pro rata share of such unreimbursed drawing
                  in same day funds on the day of notification by the Issuing
                  Lender of an unreimbursed drawing pursuant to the provisions
                  of Section 2.17.4. The obligation of each Lender to so
                  reimburse the Issuing Lender shall be absolute and
                  unconditional and shall not be affected by the occurrence of a
                  Default, an Event of Default or any other occurrence or event.
                  Any such reimbursement shall not relieve or otherwise impair
                  the obligation of the Borrower to reimburse the Issuing Lender
                  under any Letter of Credit, together with interest as
                  hereinafter provided.

                  2.17.4 Reimbursement. In the event of any drawing under any
         Letter of Credit, the Issuing Lender will promptly notify the Borrower.
         Unless the Borrower shall immediately notify the Issuing Lender that
         the Borrower intends to otherwise reimburse the Issuing Lender for such
         drawing, the Borrower shall be deemed to have requested that the
         Lenders

                                       39
<PAGE>

         make a Revolving Credit Loan in the amount of the drawing as provided
         in Section 2.17.5 on the related Letter of Credit, the proceeds of
         which will be used to satisfy the related reimbursement obligations.
         The Borrower promises to reimburse the Issuing Lender on the day of
         drawing under any Letter of Credit (either with the proceeds of a
         Revolving Credit Loan obtained hereunder or otherwise) in same day
         funds. If the Borrower shall fail to reimburse the Issuing Lender as
         provided hereinabove, the Borrower promises to pay the Issuing Lender
         interest on the unreimbursed amount of such drawing on demand at a per
         annum rate equal to two percent (2%) over the Alternate Base Rate plus
         the Applicable Base Rate Margin. The Borrower's reimbursement
         obligations hereunder shall be absolute and unconditional under all
         circumstances irrespective of any rights of setoff, counterclaim or
         defense to payment the Borrower may claim or have against the Issuing
         Lender, the Agent, the Lenders, the beneficiary of the Letter of Credit
         drawn upon or any other Person, including without limitation any
         defense based on any failure of the Borrower or any other Credit Party
         to receive consideration or the legality, validity, regularity or
         unenforceability of the Letter of Credit. The Issuing Lender will
         promptly notify the other Lenders of the amount of any unreimbursed
         drawing and each Lender shall promptly pay to the Agent for the account
         of the Issuing Lender in Dollars and in immediately available funds,
         the amount of such Lender's pro rata share of such unreimbursed
         drawing. Such payment shall be made on the day such notice is received
         by such Lender from the Issuing Lender if such notice is received at or
         before 2:00 P.M. (Charlotte, North Carolina time), and otherwise such
         payment shall be made at or before 12:00 Noon (Charlotte, North
         Carolina time) on the Business Day next succeeding the day such notice
         is received. If such Lender does not pay such amount to the Issuing
         Lender in full upon such request, such Lender shall, on demand, pay to
         the Agent for the account of the Issuing Lender interest on the unpaid
         amount during the period from the date of such drawing until such
         Lender pays such amount to the Issuing Lender in full at a rate per
         annum equal to, if paid within two (2) Business Days of the date that
         such Lender is required to make payments of such amount pursuant to the
         preceding sentence, the Federal Funds Rate and thereafter at a rate
         equal to the Base Rate. Each Lender's obligation to make such payment
         to the Issuing Lender, and the right of the Issuing Lender to receive
         the same, shall be absolute and unconditional, shall not be affected by
         any circumstance whatsoever and without regard to the termination of
         this Credit Agreement or the Commitments hereunder, the existence of a
         Default or Event of Default or the acceleration of the obligations of
         the Borrower hereunder and shall be made without any offset, abatement,
         withholding or reduction whatsoever. Simultaneously with the making of
         each such payment by a Lender to the Issuing Lender, such Lender shall,
         automatically and without any further action on the part of the Issuing
         Lender or such Lender, acquire a Participation Interest in an amount
         equal to such payment (excluding the portion of such payment
         constituting interest owing to the Issuing Lender) in the related
         unreimbursed drawn portion of the LOC Obligation and in the interest
         thereon and in the related LOC Documents, and shall have a claim
         against the Borrower with respect thereto.

                  2.17.5 Repayment with Revolving Credit Loans. On any day on
         which the Borrower shall have requested, or been deemed to have
         requested, a Revolving Credit Loan advance to reimburse a drawing under
         a Letter of Credit, the Agent shall give notice to the Lenders that a
         Revolving Credit Loan has been requested or deemed requested by the
         Borrower to be made in connection with a drawing under a Letter of
         Credit, in which case a

                                       40
<PAGE>

         Revolving Credit Loan advance comprised of Base Rate Loans (or LIBOR
         Loans to the extent the Borrower has complied with the procedures of
         Section 2.5 with respect thereto) shall be immediately made to the
         Borrower by all Lenders (notwithstanding any termination of the
         Commitments pursuant to Section 8.2.2) pro rata based on the respective
         Commitment Percentages of the Lenders (determined before giving effect
         to any termination of the Commitments pursuant to Section 8.2.2) and
         the proceeds thereof shall be paid directly to the Issuing Lender for
         application to the respective LOC Obligations. Each such Lender hereby
         irrevocably agrees to make its pro rata share of each such Revolving
         Credit Loan immediately upon any such request or deemed request in the
         amount, in the manner and on the date specified in the preceding
         sentence notwithstanding (i) the amount of such borrowing may not
         comply with the minimum amount for advances of Revolving Credit Loans
         otherwise required hereunder, (ii) whether any conditions specified in
         Section 3.2 are then satisfied, (iii) whether a Default or an Event of
         Default then exists, (iv) failure for any such request or deemed
         request for Revolving Credit Loan to be made by the time otherwise
         required hereunder, (v) whether the date of such borrowing is a date on
         which Revolving Credit Loans are otherwise permitted to be made
         hereunder or (vi) any termination of the Commitments relating thereto
         immediately prior to or contemporaneously with such borrowing. In the
         event that any Revolving Credit Loan cannot for any reason be made on
         the date otherwise required above (including, without limitation, as a
         result of the commencement of a proceeding under the Bankruptcy Code
         with respect to the Borrower or any other Credit Party), then each such
         Lender hereby agrees that it shall forthwith purchase (as of the date
         such borrowing would otherwise have occurred, but adjusted for any
         payments received from the Borrower on or after such date and prior to
         such purchase) from the Issuing Lender such Participation Interests in
         the outstanding LOC Obligations as shall be necessary to cause each
         such Lender to share in such LOC Obligations ratably (based upon the
         respective Commitment Percentages of the Lenders (determined before
         giving effect to any termination of the Commitments pursuant to Section
         8.2.2)), provided that at the time any purchase of Participation
         Interests pursuant to this sentence is actually made, the purchasing
         Lender shall be required to pay to the Issuing Lender, to the extent
         not paid to the Issuing Lender by the Borrower in accordance with the
         terms of subsection (d) above, interest on the principal amount of
         Participation Interests purchased for each day from and including the
         day upon which such borrowing would otherwise have occurred to but
         excluding the date of payment for such Participation Interests, at the
         rate equal to, if paid within two (2) Business Days of the date of the
         Revolving Credit Loan advance, the Federal Funds Rate, and thereafter
         at a rate equal to the Base Rate.

                  2.17.6 Designation of Borrower Entities as Account Parties.
         Notwithstanding anything to the contrary set forth in this Agreement,
         including without limitation Section 2.17.1, a Letter of Credit issued
         hereunder may contain a statement to the effect that such Letter of
         Credit is issued for the account of any Subsidiary of the Borrower,
         provided that notwithstanding such statement, the Borrower shall be the
         actual account party for all purposes of this Agreement for such Letter
         of Credit and such statement shall not affect the Borrower's
         reimbursement obligations hereunder with respect to such Letter of
         Credit.

                                       41
<PAGE>

                  2.17.7 Renewal, Extension. The renewal or extension of any
         Letter of Credit shall, for purposes hereof, be treated in all respects
         the same as the issuance of a new Letter of Credit hereunder.

         Standby Practices 1998 (the "ISP98"), in either case as published as of
         the date of issue by the International Chamber of Commerce, in which
         case the UCP or the ISP98, as applicable, may be incorporated therein
         and deemed in all respects to be a part thereof.

                  2.17.9   Indemnification; Nature of Issuing Lender's Duties.

                           (i) In addition to its other obligations under this
                  Section 2.17, the Borrower hereby agrees to pay, and protect,
                  indemnify and save each Lender harmless from and against, any
                  and all claims, demands, liabilities, damages, losses, costs,
                  charges and expenses (including reasonable attorneys' fees)
                  that such Lender may incur or be subject to as a consequence,
                  direct or indirect, of (A) the issuance of any Letter of
                  Credit or (B) the failure of such Lender to honor a drawing
                  under a Letter of Credit as a result of any act or omission,
                  whether rightful or wrongful, of any present or future de jure
                  or de facto government or Governmental Authority (all such
                  acts or omissions, herein called "Government Acts").

                           (ii) As between the Borrower and the Lenders
                  (including the Issuing Lender), the Borrower shall assume all
                  risks of the acts, omissions or misuse of any Letter of Credit
                  by the beneficiary thereof. No Lender (including the Issuing
                  Lender) shall be responsible: (A) for the form, validity,
                  sufficiency, accuracy, genuineness or legal effect of any
                  document submitted by any party in connection with the
                  application for and issuance of any Letter of Credit, even if
                  it should in fact prove to be in any or all respects invalid,
                  insufficient, inaccurate, fraudulent or forged; (B) for the
                  validity or sufficiency of any instrument transferring or
                  assigning or purporting to transfer or assign any Letter of
                  Credit or the rights or benefits thereunder or proceeds
                  thereof, in whole or in part, that may prove to be invalid or
                  ineffective for any reason; (C) for errors, omissions,
                  interruptions or delays in transmission or delivery of any
                  messages, by mail, cable, telegraph, telex or otherwise,
                  whether or not they be in cipher; (D) for any loss or delay in
                  the transmission or otherwise of any document required in
                  order to make a drawing under a Letter of Credit or of the
                  proceeds thereof; and (E) for any consequences arising from
                  causes beyond the control of such Lender, including, without
                  limitation, any Government Acts. None of the above shall
                  affect, impair, or prevent the vesting of the Issuing Lender's
                  rights or powers hereunder.

                           (iii) In furtherance and extension and not in
                  limitation of the specific provisions hereinabove set forth,
                  any action taken or omitted by any Lender (including the
                  Issuing Lender), under or in connection with any Letter of
                  Credit or the related certificates, if taken or omitted in
                  good faith, shall not put such Lender

                                       42
<PAGE>

                  under any resulting liability to the Borrower or any other
                  Credit Party. It is the intention of the parties that this
                  Agreement shall be construed and applied to protect and
                  indemnify each Lender (including the Issuing Lender) against
                  any and all risks involved in the issuance of the Letters of
                  Credit, all of which risks are hereby assumed by the Borrower
                  (on behalf of itself and each of the other Credit Parties),
                  including, without limitation, any and all Government Acts. No
                  Lender (including the Issuing Lender) shall, in any way, be
                  liable for any failure by such Lender or anyone else to pay
                  any drawing under any Letter of Credit as a result of any
                  Government Acts or any other cause beyond the control of such
                  Lender.

                           (iv) Nothing in this Section 2.17.9 is intended to
                  limit the reimbursement obligations of the Borrower contained
                  in Section 2.17.4 above. The obligations of the Borrower under
                  this Section 2.17.9 shall survive the termination of this
                  Agreement. No act or omission of any current or prior
                  beneficiary of a Letter of Credit shall in any way affect or
                  impair the rights of the Lenders (including the Issuing
                  Lender) to enforce any right, power or benefit under this
                  Agreement.

                           (v) Notwithstanding anything to the contrary
                  contained in this Section 2.17.9, the Borrower shall have no
                  obligation to indemnify any Lender (including the Issuing
                  Lender) in respect of any liability incurred by such Lender
                  (A) arising solely out of the gross negligence or willful
                  misconduct of such Lender, as determined by a court of
                  competent jurisdiction, or (B) caused by such Lender's failure
                  to pay under any Letter of Credit after presentation to it of
                  a request strictly complying with the terms and conditions of
                  such Letter of Credit, as determined by a court of competent
                  jurisdiction, unless such payment is prohibited by any law,
                  regulation, court order or decree.

                  2.17.10 Responsibility of Issuing Lender. It is expressly
         understood and agreed that the obligations of the Issuing Lender
         hereunder to the Lenders are only those expressly set forth in this
         Agreement and that the Issuing Lender shall be entitled to assume that
         the conditions precedent set forth in Section 3.2 have been satisfied
         unless it shall have acquired actual knowledge that any such condition
         precedent has not been satisfied; provided, however, that nothing set
         forth in this Section 2.17 shall be deemed to prejudice the right of
         any Lender to recover from the Issuing Lender any amounts made
         available by such Lender to the Issuing Lender pursuant to this Section
         2.17 in the event that it is determined by a court of competent
         jurisdiction that the payment with respect to a Letter of Credit
         constituted gross negligence or willful misconduct on the part of the
         Issuing Lender.

                  2.17.11 Conflict with LOC Documents. In the event of any
         conflict between this Agreement and any LOC Document (including any
         letter of credit application), this Agreement shall control.

         2.18     PAYMENTS.

                  Except as otherwise specifically provided herein, all payments
         hereunder shall be made to the Agent in Dollars in immediately
         available funds, without condition or deduction

                                       43
<PAGE>

         for any counterclaim, defense, recoupment or setoff of any kind, at the
         Agent's office specified in Section 10.1 not later than 2:00 P.M.
         (Charlotte, North Carolina time) on the date when due. Payments
         received after such time shall be deemed to have been received on the
         next succeeding Business Day. The Agent may (but shall not be obligated
         to) debit the amount of any such payment which is not made by such time
         to any ordinary deposit account of the Borrower or any other Credit
         Party maintained with the Agent (with notice to the Borrower or such
         other Credit Party). The Borrower shall, at the time it makes any
         payment under this Credit Agreement, specify to the Agent the Loans,
         LOC Obligations, fees, interest or other amounts payable by the
         Borrower hereunder to which such payment is to be applied (and in the
         event that it fails so to specify, or if such application would be
         inconsistent with the terms hereof, the Agent shall distribute such
         payment to the Lenders in such manner as the Agent may determine to be
         appropriate in respect of obligations owing by the Borrower hereunder,
         subject to the terms of Section 9.5). The Agent will distribute such
         payments to such Lenders, if any such payment is received prior to 2:00
         P.M. (Charlotte, North Carolina time) on a Business Day in like funds
         as received prior to the end of such Business Day and otherwise the
         Agent will distribute such payment to such Lenders on the next
         succeeding Business Day. Whenever any payment hereunder shall be stated
         to be due on a day which is not a Business Day, the due date thereof
         shall be extended to the next succeeding Business Day (subject to
         accrual of interest and fees for the period of such extension), except
         that in the case of LIBOR Loans, if the extension would cause the
         payment to be made in the next following calendar month, then such
         payment shall instead be made on the next preceding Business Day.

         The delivery of each Borrowing Notice and each request for a Letter of
Credit pursuant to Section 2.17 shall constitute a representation and warranty
by the Borrower of the correctness of the matters specified in Section 3.2.2,
3.2.3, 3.2.4, 3.2.5 and 3.2.6 above.

                       IV. REPRESENTATIONS AND WARRANTIES

         The Borrower represents and warrants to the Lenders and the Agent that:

         4.1      CAPACITY.

         Each Borrower Entity is duly organized, validly existing and in good
standing under the laws of the jurisdiction of its incorporation or
organization. Each Borrower Entity is qualified or authorized to do business in
all jurisdictions in which its ownership of property or conduct of business
requires such qualification or authorization or where thc failure to be so
qualified or authorized would not have a Material Adverse Effect. Each Borrower
Entity has the power and authority to own its Properties and to carry on its
business as now being conducted and as proposed to be conducted after the
execution hereof, to execute and deliver this Agreement and the other Loan
Documents, and to perform its obligations hereunder and under the other Loan
Documents.

         4.2      AUTHORIZATION.

         The execution, delivery and performance of this Agreement and the other
Loan Documents by each Borrower Entity executing such documents has been duly
authorized by all requisite action.

         4.3      BINDING OBLIGATIONS.

         This Agreement and the other Loan Documents, when executed and
delivered to the Agent and the Lenders, will be, legal, valid and binding upon
each Borrower Entity who is a party thereto, enforceable in accordance with its
respective terms, subject only to principles of equity and laws applicable to
creditors generally, including bankruptcy laws.

         4.4      NO CONFLICTING LAW OR AGREEMENT.

         The execution, delivery and performance of this Agreement and the other
Loan Documents by each Borrower Entity does not constitute a breach of or
default under, and will not violate or conflict with, any provisions of the
corporate charter or other constituent documents of a Borrower Entity; any
contract, financing agreement, lease, or other agreement to which a Borrower
Entity is a party or by which its Properties may be affected, the violation of
which would have a Material Adverse Effect; or any Law to which a Borrower
Entity is subject or by which its Properties may be affected, the violation of
which would have a Material Adverse Effect; nor will the same result in the
creation or imposition of any Encumbrance upon any Property of any Borrower
Entity, other than those contemplated by the Loan Documents.

                                       48
<PAGE>

         4.5      NO CONSENT REQUIRED.

         The execution, delivery, and performance of this Agreement and the
other Loan Documents by the Borrower Entities do not require the consent or
approval of or the giving of notice to any Person except for those consents
which have been duly obtained and are in full force and effect on the date
hereof and others, if any, which by their omission would not result in a
Material Adverse Effect.

         4.6      FINANCIAL STATEMENTS.

         The Financial Statements and the financial statements delivered to the
Lenders pursuant to Section 5.3.1 and 5.3.2, are complete and correct, have been
prepared in accordance with GAAP, and present fairly the financial condition and
results of operations of the Borrower Entities as of the date and for the period
stated therein, subject to year-end adjustments. No Material Adverse Change has
occurred since December 31, 2001. The Borrower acknowledges that the Lenders
have advanced (or shall advance) the Revolving Credit Loans and the Swingline
Loans in reliance upon the Financial Statements.

         4.7      FISCAL YEAR.

         The Borrower's fiscal year ends on December 31 of each year.

         4.8      LITIGATION.

         There is no litigation, arbitration, legal or administrative
proceeding, tax audit, investigation, or other action or proceeding of any
nature pending against any Borrower Entity or any of its Properties which, if
adversely determined, would likely have a Material Adverse Effect, and there is
no litigation, arbitration, legal or administrative proceeding, tax audit,
investigation, or other action or proceeding of any nature threatened in writing
against a Borrower Entity which, if adversely determined, would have a Material
Adverse Effect. No Borrower Entity is subject to any outstanding court, arbitral
or administrative order, writ or injunction. To the best of the Borrower's
knowledge, information and belief, no facts exist under which third parties have
unasserted claims against any Borrower Entity which, if adversely determined,
would have a Material Adverse Effect.

         4.9      TAXES; GOVERNMENTAL CHARGES.

         Each Borrower Entity has filed or caused to be filed or has lawfully
extended the deadline for filing all tax returns and reports required to be
filed, other than those which, if not filed, would not have a Material Adverse
Effect. Each Borrower Entity has paid, or made adequate provision for the
payment of, all taxes, assessments and other governmental charges that have or
may have become due pursuant to such returns or otherwise, or pursuant to any
assessment received by it, except such taxes, etc., if any, as are being
contested in good faith by appropriate proceedings and for which adequate
reserves have been provided. To the best of the Borrower's knowledge, there is
no proposed material tax assessment against any Borrower Entity. No extension of
time for the assessment of federal, state or local taxes of any Borrower

                                       49
<PAGE>

Entity is in effect or has been requested. Each Borrower Entity has timely made
all required remittances of withholding deposits and other assessments against
payroll expenditures except for matters that would not have a Material Adverse
Effect.

         4.10     TITLE TO PROPERTIES.

         Each Borrower Entity has good and marketable title to its Properties,
free and clear of all Encumbrances except for Permitted Encumbrances.

         4.11     NO DEFAULT.

         No Borrower Entity is in default in any respect that affects its
business, Properties, operations, or condition, financial or otherwise, under
any indenture, mortgage, deed of trust, obligation to equity holders, credit
agreement, note, agreement, lease, sale agreement or other instrument to which
any Borrower Entity is a party or by which its Properties are bound, which
default would have a Material Adverse Effect. To the best of the Borrower's
knowledge, information and belief, no other party to any contract with any
Borrower Entity under which a default would have a Material Adverse Effect is in
default or breach thereof and no circumstances exist which, with the giving of
notice and/or the passing of time would constitute such default or breach. No
Default or Event of Default exists under this Agreement.

         4.12     CASUALTIES; TAKING OF PROPERTIES.

         Neither the business nor the Property of any Borrower Entity is
presently impaired as a result of any fire, explosion, earthquake, flood,
drought, windstorm, accident, strike or other labor disturbance, embargo,
requisition or taking of property, cancellation of contracts, permits,
concessions by any domestic or foreign government or any agency thereof, riot,
activities of armed forces or acts of God or of any public enemy, in any case as
would have a Material Adverse Effect.

         4.13     COMPLIANCE WITH LAWS.

         No Borrower Entity is in violation of any Law to which it, its business
or any of its Properties are subject, the violation of which would likely have a
Material Adverse Effect, and there are no outstanding citations, notices or
orders of noncompliance issued to any Borrower Entity under any such Law, the
violation of which would likely have a Material Adverse Effect. Each Borrower
Entity has obtained all licenses, permits, franchises, or other governmental
authorizations necessary to the ownership of its Properties or to the conduct of
its business, except for those which, if not obtained, would not have a Material
Adverse Effect.

         4.14     COMPLIANCE WITH FRAUD AND ABUSE LAWS.

         Without limiting any other provision of this Agreement, (a) no Borrower
Entity is in violation of any Fraud and Abuse Law, the violation of which would
have a Material Adverse Effect and (b) to the best knowledge of the Credit
Parties, no Provider is in violation of any Fraud and Abuse Law, the violation
of which would have a Material Adverse Effect.

                                       50
<PAGE>

         4.15     ERISA.

         No ERISA Event has occurred with respect to any Plan or is reasonably
expected to occur with respect to any Plan, except for those which, if not
obtained, would not have a Material Adverse Effect.

         4.16     FULL DISCLOSURE OF MATERIAL FACTS.

         The Borrower has fully advised the Agent of all matters involving the
financial condition, business, operations and Properties of the Borrower
Entities that would be reasonably expected to have a Material Adverse Effect. No
information, exhibit, or report furnished or to be furnished by the Borrower to
the Lenders in connection with this Agreement contains, as of the date thereof,
any misrepresentation of fact or failed or will fail to state any material fact,
the omission of which would render the statements therein materially false or
misleading.

         4.17     INVESTMENT COMPANY ACT.

         No Borrower Entity is an "investment company" registered or required to
be registered under the Investment Company Act of 1940, as amended, and is not
controlled by such a company.

         4.18     HOLDING COMPANY.

         No Borrower Entity is subject to regulation under the Public Utility
Holding Company Act of 1935 or the Federal Power Act. In addition, no Borrower

or an "affiliate" of a "holding company" or of a "subsidiary" of a "holding
company", within the meaning of the Public Utility Holding Company Act of 1935,
as amended. No Borrower Entity is a "personal holding company" as defined in
Section 542 of the IRC.

         4.19     SOLVENCY.

         The Credit Parties are Solvent on a consolidated basis.

         4.20     SUBSIDIARIES.

to the Borrower and each of its direct and indirect Subsidiaries of (i) number
of shares of each class of Capital Stock outstanding, (ii) number and percentage
of outstanding shares of each class owned (directly or indirectly) by the
Borrower Entities and (iii) number and effect, if exercised, of all outstanding

with respect thereto. The outstanding Capital Stock of all such Persons is
validly issued, fully paid and non-assessable and is owned by the Borrower
Entities, directly or indirectly, in the manner set forth on Schedule 4.20, free
and clear of all Encumbrances (other than those arising under or contemplated in
connection with the Loan Documents). Other than as set forth in Schedule 4.20,
neither the

                                       51
<PAGE>

Borrower nor any of its Subsidiaries has outstanding any securities convertible
into or exchangeable for its Capital Stock nor does any such Person have
outstanding any rights to subscribe for or to purchase or any options for the
purchase of, or any agreements providing for the issuance (contingent or
otherwise) of, or any calls, commitments or claims of any character relating to
its Capital Stock. Also set forth on Schedule 4.20 is the jurisdiction of
incorporation or formation of the Borrower and each of its Subsidiaries.

         The Borrower Entities own all licenses, permits, franchises,
registrations, patents, copyrights, trademarks, trade names or service marks, or
the rights to use the foregoing, that are necessary for the continued operation
of their business except for such licenses, permits, franchises, registrations,
patents, copyrights, trademarks, trade names or service marks, which, if not
held or owned, would not have a Material Adverse Effect.

         4.22     ENVIRONMENTAL COMPLIANCE.

         Each Borrower Entity has duly complied with, and their Properties are
owned and operated in compliance with, all Environmental Laws, the violation of
which would have a Material Adverse Effect. There have been no citations,
notices or orders of non-compliance issued to any Borrower Entity or, to the
best of the Borrower's knowledge, relating to their business or Properties
pursuant to any Environmental Law, except for those which would not have a
Material Adverse Effect. Each Borrower Entity has obtained all required federal,
state and local licenses, certificates or permits relating to them and their
Properties as required by applicable Environmental Laws, except for those which,
if not obtained, would not have a Material Adverse Effect.

         4.23     LABOR MATTERS.

         No Borrower Entity is subject to any collective bargaining agreements
or any decrees or orders requiring them to recognize, deal with or employ any
Person. No demand for collective bargaining has been asserted against any
Borrower Entity by any union or organization. No Borrower Entity has experienced
any strike, labor dispute, slowdown or work stoppage due to labor dispute and,
to the best knowledge of the Borrower, there is no such strike, dispute,
slowdown or work stoppage threatened against any Borrower Entity. All Borrower
Entities are in compliance in all material respects with the Fair Labor
Standards Act of 1938, as amended, except for those matters which would not have
a Material Adverse Effect.

         4.24     OSHA COMPLIANCE.

         The Borrower hereby covenants and agrees that so long as this Agreement
is in effect or any amounts payable hereunder or under any other Loan Document
shall remain outstanding, and until all of the Commitments hereunder shall have
terminated (and thereafter where expressly stated herein):

         5.1      PAYMENT OF OBLIGATIONS.

         The Borrower shall pay all amounts owed under the Obligations when due
without setoff, counterclaim or withholdings of any kind; provided, however, if
the Borrower is required by law to withhold any taxes (other than taxes based
upon the income of the Lender imposed by the jurisdiction in which the Lender is
organized or from which its interest herein has been generated) from any
payments on the Obligations to any Lender(s), the Borrower shall make additional
payments to such Lender(s) along with the regular payments as they become due so
that the end result is that such Lender(s) receives the amount that the
Lender(s) would have received if no such withholdings were made.

         5.2      MAINTENANCE OF EXISTENCE.

         Except for transactions permitted under Section 6.6, each Borrower
Entity shall (a) maintain its fundamental existence, name, material rights, and
franchises and (b) maintain its qualification and good standing in all states in
which such qualification is necessary (except to the extent that failure to so
qualify would not have a Material Adverse Effect).

<PAGE>

         5.3      FINANCIAL STATEMENTS AND REPORTS.

         consolidated and consolidating balance sheets and income statements and
         consolidated statements of cash flows of the Borrower and the other
         Borrower Entities for and as of the end of the preceding fiscal
         quarter, all prepared by the Borrower on a consolidated (and
         consolidating, as applicable) basis and certified by the Borrower's
         president or chief financial officer to be complete and correct and to

         and required footnote disclosures), the financial condition of the
         Borrower and its consolidated affiliates as of the date of such
         statements and the results of their operations for such period. The
         quarterly financial information shall further include calculations of
         all financial ratios, the certification of the Borrower's president or

         consolidated affiliates at the close of such year and the results of
         its operations during such year. The annual audited financial
         statements shall be accompanied by unaudited consolidating financial
         statements for all the Borrower Entities, except that consolidating
         statements of cash flows shall not be required. The annual financial
         information shall include calculations of all financial ratios as
         determined based upon the audited financial statements and the
         certification of the Borrower's president or chief financial officer as

         than fifteen (15) days after the filing thereof, the Borrower shall
         deliver copies of all regular, periodic and special reports that any

         Entity.

                  5.3.8 Notice Upon Perceived Breach. The Borrower agrees to
         give prompt written notice of any action or inaction by or on behalf of
         the Agent or any Lender in connection with this Agreement or the

         party or a defense to payment of any or all of the Obligations for any
         reason, including, but not limited to, commission of a tort or
         violation of any contractual duty or duty implied by law.

                  5.3.9 Changes in Constituent Document. The Borrower shall give
         prompt written notice of any material change in the corporate charter
         or bylaws of the Borrower or any Subsidiary following the encumbrance
         of the stock thereof in favor of the Agent as required under this
         Agreement, and shall provide the Agent with a copy of such change
         (Borrower Entities are restricted in the adoption of such amendments as
         provided elsewhere in the Loan Documents, and nothing contained in this
         Section shall be deemed a waiver of such restrictions).

                  5.3.10 Notice of Litigation. The Borrower shall give prompt
         written notice of any litigation, arbitration, tax audit,
         administrative proceeding or investigation that may hereafter be
         instituted or threatened in writing in which the Borrower would be a

         business, operations or Properties, except for (i) actions seeking

         Consolidated EBITDA calculated over the most recent four fiscal

         arising from premises or vehicular liability seeking only monetary

         written notice if the Borrower learns of the occurrence of (i) any
         event that constitutes a Default or an Event of Default, together with
         a detailed statement of the steps being taken as a result thereof, or
         (ii) any Material Adverse Change.

                  5.3.12 Other Information. The Borrower shall promptly provide
         such other information respecting the condition or operations,
         financial or otherwise, of the Borrower Entities as the Agent or any
         Lender may from time to time reasonably request.

         5.4      TAXES AND OTHER ENCUMBRANCES.

         Each Borrower Entity shall make due and timely payment or deposit of
all federal, state and local taxes, assessments or contributions required of it
by law, and execute and deliver to the Agent, on demand, appropriate
certificates attesting to the payment or deposit thereof; provided, however,
that the Borrower Entities shall not be required to pay or discharge any such
tax, assessment, charge or claim for as long as it is being diligently contested
in good faith by proper proceedings and for which appropriate reserves are being
maintained.

         5.5      PAYMENT OF DEBTS.

         Each Borrower Entity shall pay all of its Debts as and when the same
become due in accordance with their terms, except for such Debts being contested
in good faith by appropriate proceedings and for which adequate reserves have
been established on the books of such Borrower Entity in accordance with GAAP,
unless the failure to make any such payment could have a Material Adverse
Effect.

         5.6      COMPLIANCE WITH LAWS.

         Each Borrower Entity shall observe and comply with all Laws (including,
but not limited to, Fraud and Abuse Laws), and shall maintain all certificates,
franchises, permits, licenses, and authorizations necessary to the conduct of
its business or the operation of its Properties, except for such Laws,
certificates, franchises, permits, licenses and authorizations which, if
violated or not obtained and full penalties were imposed for such violation,
would not cause a Material Adverse Effect. Each Borrower Entity shall further
use its best efforts to assure the compliance by all Providers with all
applicable Laws, including, but not limited to, medical licensure and Fraud and
Abuse Laws, relating to their providing of professional services, except for
those which, if violated and full penalties were imposed for such violation,
would not cause a Material Adverse Effect.

         5.7      MAINTENANCE OF PROPERTY.

         All Borrower Entities shall maintain their Property (and any Property
leased by or consigned or held under title retention or conditional sales
contracts) in good and workable condition at all times, subject to ordinary wear

obsolescence, and shall make all repairs, replacements, additions, and
improvements to their Property reasonably necessary and proper to cause the

         5.8      COMPLIANCE WITH CONTRACTUAL OBLIGATIONS.

         Each Borrower Entity will perform all of its obligations in respect of
all material contracts to which it is a party and will use its best efforts to
keep, and to take all action to keep, such contracts in full force and effect
and not allow any such contract to lapse or be terminated or any rights to renew
such to be forfeited or canceled, if such lapse, termination, forfeiture or
cancellation would have a Material Adverse Effect; provided, however, that any
such contract may lapse or be terminated or such renewal rights may be forfeited
or canceled if in the reasonable business judgment of the Borrower Entities it
is in their best interests to allow or cause such lapse, termination, forfeiture
or cancellation.

         5.9      FURTHER ASSURANCES.

         The Borrower Entities shall promptly cure any defects in the creation,
issuance, or delivery of the Loan Documents. The Borrower Entities at their
expense will execute (or cause to be executed) and deliver to the Agent upon
request all such other and further documents, agreements, and instruments in
compliance with or accomplishment of the covenants and agreements applicable to
them in the Loan Documents, or to evidence further and to describe more fully
any Collateral intended as security for the Obligations, or to correct any
omissions in the Loan Documents, or to state more fully the Obligations and
agreements set out in any of the Loan Documents, or to perfect, protect, or
preserve any Encumbrances created pursuant to any of the Loan Documents, or to
make any recordings, to file any notices, or to obtain any consents, all as the
Agent may reasonably request. The Borrower appoints the Agent as the Borrower's
attorney-in-fact to execute any financing statements or other instruments of
perfection with respect to the Collateral.

         5.10     SECURITY INTEREST; SETOFF.

         In order further to secure the payment of the Obligations, the Borrower
hereby grants to the Agent and to each Lender a security interest and right of
setoff against all of the Borrower's presently owned or hereafter acquired
monies, items, credits, deposits and instruments (including certificates of
deposit) presently or hereafter in the possession of any Lender or the Agent. By
maintaining any such accounts or other property with a Lender or the Agent, the
Borrower acknowledges that the Borrower voluntarily subjects the property to the
security interest arising hereunder. Subject to the provisions in Article IX
hereof, a Lender may exercise its rights under this Section without prior notice
(but with prompt notice following the setoff) following an Event of Default. The
Borrower agrees that neither the Lenders nor the Agent shall be liable for the
dishonor of any instrument after notice of setoff shall have been duly given
resulting from a Lender's exercise of its rights under this Section.

         5.11     INSURANCE.

                  5.11.1 General Insurance Requirements. In addition to any
         other specific requirements set forth in this Agreement and in other
         Loan Documents, all the Borrower Entities shall maintain insurance on
         all insurable Properties now or hereafter owned by them against such
         risks and to the extent customary in their industry, and shall maintain

                                       57
<PAGE>

         or cause to be maintained public liability and worker's compensation
         insurance to the extent customary in the industry. The present casualty
         insurance coverage of the Borrower Entities is outlined as to carrier,
         policy number, expiration date, type and amount on Schedule 5.11.

                  5.11.2 Practice-Related Insurance Requirements. All Borrower
         Entities shall maintain insurance for claims, however characterized,
         against such Borrower Entities in connection with the provision of
         medical services by Providers and/or ancillary services provided by
         such Borrower Entities, in an amount of at least $1,000,000.00 per
         occurrence, with such deductibles as are in accordance with normal
         industry practice for entities the size and nature of the Borrower
         Entities on a consolidated basis. The present liability insurance
         coverage of the Borrower Entities is outlined as to carrier, policy
         number, expiration date, type and amount on Schedule 5.11.

         5.12     ACCOUNTS AND RECORDS.

         The Borrower Entities shall maintain current books of record and
account, in which full, true, and correct entries will be made of all
transactions.

         5.13     OFFICIAL RECORDS.

         The Borrower Entities shall maintain current corporate and official
records, minute books and stock ledgers.

         The Borrower Entities shall permit any officer, employee, or agent of a
Lender or the Agent to visit and inspect during ordinary business hours any of
their Property, to examine their books of record and accounts and corporate
records, to take copies and extracts from such books of record and accounts, and
to discuss the affairs, finances, and accounts of the Borrower Entities with
their respective officers, accountants, and auditors, all at such reasonable
times and as often as the Agent or a Lender may reasonably desire and upon
reasonable advance notice absent an Event of Default. Without limiting the
Agent's right to obtain equitable relief as to any other appropriate right in
this Agreement or in other Loan Documents, the Borrower agrees that the rights
in this Section may be enforced by affirmative injunction and, to the extent the
right to review records may be denied, the right may be enforced by a
restraining order prohibiting the interference by the Borrower with the exercise
of rights to review of the records pursuant to this Section. Absent an Event of
Default, all expenses of such inspections, etc. shall be paid by the respective
Lenders, and in the presence of an Event of Default, all reasonable expenses
thereof shall be paid by the Borrower.

are a party, except for matters which would not have a Material Adverse Effect.
The Borrower Entities shall (i) upon request, provide the Agent with copies of
any annual report required to be filed pursuant to ERISA with respect to any
Plan or any other employee benefit plan; (ii) notify the Agent upon the
occurrence of any ERISA Event or of any additional act or condition arising in
connection with any Plan which they believe might constitute grounds for
termination thereof by the PBGC or for the appointment of a trustee to
administer the Plan; and (iii) furnish to the Agent, promptly upon request, such
additional information concerning any Plan or any other employee benefit plan as
the Agent may request.

         5.17     INDEMNITY; EXPENSES.

         Whether or not the transactions contemplated hereby are consummated,
the Borrower agrees to indemnify, save and hold harmless the Agent, each Lender
and their respective Affiliates, directors, officers, employees, counsel, agents
and attorneys-in-fact (collectively the "Indemnitees") from and against: (a) any
and all claims, demands, actions or causes of action that are asserted against
any Indemnitee by any Person (other than the Agent or any Lender) relating
directly or indirectly to a claim, demand, action or cause of action that such
Person asserts or may assert against any Credit Party, any Affiliate of any
Credit Party or any of their respective officers or directors; (b) any and all
claims, demands, actions or causes of action that may at any time (including at

any foregoing claim, demand, action, cause of action or proceeding, or as a
result of the preparation of any defense in connection with any foregoing claim,
demand, action, cause of action or proceeding, in all cases, whether or not
arising out of the negligence of an Indemnitee, and whether or not an Indemnitee
is a party to such claim, demand, action, cause of action or proceeding (all the
foregoing, collectively, the "Indemnified Liabilities"); provided that no
Indemnitee shall be entitled to indemnification for any claim caused by its own
gross negligence or willful misconduct or for any loss asserted against it by
another Indemnitee. The agreements in this Section shall survive the termination
of the Commitments and repayment of all the other Obligations.

                  5.17.1 Taxes. All taxes that the Lenders or the Agent may be
         required to pay because of the Obligations or because of the Lenders'

         ordinary activities that are not occasioned by a Default or an Event of
         Default or by a request of the Borrower to waive or vary the terms of

         association with any of the Borrower Entities, including, but not

                  5.21.1 Compliance With Environmental Laws. All Borrower
         Entities will (i) employ in connection with their operations,
         appropriate technology and compliance procedures to maintain compliance

         reasonably be expected to have a Material Adverse Effect, (ii) obtain
         and maintain any and all materials permits or other permits required by
         applicable Environmental Laws in connection with its operations,
         excepting only such permits, etc. which would not by their absence
         cause a Material Adverse Effect, and (iii) dispose of any and all
         Hazardous Substances only at facilities and with carriers reasonably
         believed to possess valid permits under any applicable state and local
         Environmental Laws. All Borrower Entities shall use their best efforts
         to obtain all certificates required by law to be obtained by them from
         all contractors employed by them in connection with the transport or
         disposal of any Hazardous Substances.

                  5.21.2 Remedial Work. If any investigation, site monitoring,
         containment, clean-up, removal, restoration or other remedial work of
         any kind or nature with respect to any Borrower Entity's Properties is
         required to be performed by them under any applicable local, state or
         federal law or regulation, any judicial order, or by any governmental
         or non-governmental entity or Person because of, or in connection with,
         the current or future presence, suspected presence, release or
         suspected release of a Hazardous Substance in or into the air, soil,
         groundwater, surface water or soil vapor at, on, about, under, or
         within any of a Borrower Entity's Property (or any portion thereof),
         the Borrower shall within 30 days after written demand for performance
         thereof (or such shorter period of time as may be required under
         applicable law, regulation, order or agreement), commence and
         thereafter diligently prosecute to completion, all such remedial work.

                  5.21.3 Indemnification of the Lenders and the Agent. The
         Borrower agrees to indemnify, defend (with counsel reasonably
         satisfactory to the indemnified party or parties) and hold harmless the
         Lenders and the Agent against any loss, liability claim or expense,
         including attorneys' fees, that a Lender or the Agent may incur as a
         result of the violation or alleged violation of any Environmental Law
         by a Borrower Entity or with respect to any other violation of
         Environmental Laws with respect to any Borrower Entity's Properties.
         This covenant shall survive the repayment of the Loans.

<PAGE>

         5.22     OPINIONS OF COUNSEL.

         The Borrower agrees that the Agent may from time to time, but not more
frequently than once every calendar year absent a Default or an Event of
Default, request in writing a copy of the most recent letter of in-house counsel
and/or outside healthcare counsel issued to the Borrower's auditors addressing
any material loss contingencies as to which such counsel have devoted
substantive attention. Copies of such letters shall be delivered to the Lenders
within ten (10) days after request. Additionally, the Borrower shall, within
twenty (20) days after written request, respond to such questions that may be
raised by the Agent from time to time regarding the Borrower Entities'
compliance with Fraud and Abuse Laws, and shall engage the assistance of the
Borrower's healthcare counsel for the purpose of responding to such questions if
the Agent so requests.

         Furthermore, in the event the aggregate revenues attributable to the
Non-Opinion Subsidiaries for the four fiscal quarter period most recently ending
constitutes ten percent (10%) or more of the consolidated revenues of the
Borrower and its Subsidiaries for such four fiscal quarter period, the Borrower
agrees that it shall cause outside counsel to provide a legal opinion (in form
and substance reasonably satisfactory to the Agent) to the Agent within 30 days
of such fiscal quarter end with respect to those Non-Opinion Subsidiaries
necessary to cause the aggregate revenues attributable to the Non-Opinion
Subsidiaries for the four fiscal quarter period most recently ending to be less
than ten percent (10%) of the consolidated revenues of the Borrower and its
Subsidiaries for such four fiscal quarter period. Such legal opinions shall
cover, among other things, the legality, validity, binding effect and
enforceability of the Loan Documents with respect to the applicable
Subsidiaries.

         5.23     ADDITIONAL CREDIT PARTIES.

         As soon as practicable and in any event within 30 days after any Person
becomes a Subsidiary of the Borrower, the Borrower shall provide the Agent with
written notice thereof and shall (a) if such Person is a wholly-owned Domestic
Subsidiary of a Credit Party, cause such Person to execute a Joinder Agreement
in substantially the same form as Exhibit 5.23, (b) if such Person is a Domestic
Subsidiary of a Credit Party, cause 100% of the Capital Stock of such Person
owned by such Credit Party to be delivered to the Agent (together with undated
stock powers signed in blank) or if such Person is a direct Foreign Subsidiary
of a Credit Party, cause 65% of the Capital Stock owned by such Credit Party
entitled to vote and 100% of the Capital Stock not entitled to vote of such
Person owned by such Credit Party to be delivered to the Agent (together with
undated stock powers signed in blank (unless, with respect to a Foreign
Subsidiary, such stock powers are deemed unnecessary by the Agent in its
reasonable discretion under the law of the jurisdiction of incorporation of such
Person)), and in each case pledged to the Agent pursuant to an appropriate
pledge agreement(s) any necessary perfection documents in each case in a form
reasonably acceptable to the Agent, (c) if such Person is a wholly-owned
Domestic Subsidiary of a Credit Party and has any Subsidiaries (i) deliver all
of the Capital Stock of any Domestic Subsidiaries owned by such Person and 65%
of the Capital Stock entitled to vote and 100% of the Capital Stock not entitled
to vote of any direct Foreign Subsidiaries owned by such Person (together with
undated stock powers signed in blank (unless, with respect to a Foreign
Subsidiary, such stock powers are deemed unnecessary by the Agent in its

                                       62
<PAGE>

reasonable discretion under the law of the jurisdiction of incorporation of such
Person) to the Agent and (ii) execute a pledge agreement any necessary
perfection documents in each case in a form reasonably acceptable to the Agent
and (d) deliver such documentation as the Agent may reasonably request in
connection with the foregoing, including without limitation, certified
resolutions and other organizational documents of such Person, all in form,
content and scope reasonably satisfactory to the Agent.

are in excess of $10,000,000 shall be evidenced by Inter-Company Notes pledged

         of the Lenders, in a cash collateral account as additional security for
         the LOC Obligations in respect of subsequent drawings under all then
         outstanding Letters of Credit in an amount equal to the maximum
         aggregate amount which may be drawn under all Letters of Credits then

         automatically shall immediately become due and payable and (iii) the
         Borrower automatically shall be obligated (and hereby promises) to pay

                              IX. AGENCY PROVISIONS

         9.1      APPOINTMENT AND AUTHORIZATION OF AGENT.

         (a) Each Lender hereby irrevocably (subject to Section 9.7) appoints,
designates and authorizes the Agent to take such action on its behalf under the
provisions of this Agreement and each other Loan Document and to exercise such
powers and perform such duties as are expressly delegated to it by the terms of
this Agreement or any other Loan Document, together with such powers as are
reasonably incidental thereto. Notwithstanding any provision to the contrary
contained elsewhere herein or in any other Loan Document, the Agent shall not
have any duties or responsibilities, except those expressly set forth herein,
nor shall the Agent have or be deemed to have any fiduciary relationship with
any Lender or participant, and no implied covenants, functions,
responsibilities, duties, obligations or liabilities shall be read into this
Agreement or any other Loan Document or otherwise exist against the Agent.
Without limiting the generality of the foregoing sentence, the use of the term
"agent" herein and in the other Loan Documents with reference to the Agent is
not intended to connote any fiduciary or other implied (or express) obligations
arising under agency doctrine of any applicable law. Instead, such term is used
merely as a matter of market custom, and is intended to create or reflect only
an administrative relationship between independent contracting parties.

                                       72
<PAGE>
         (b) The Issuing Lender shall act on behalf of the Lenders with respect
to any Letters of Credit issued by it and the documents associated therewith
until such time (and except for so long) as the Agent may agree at the request
of the Required Lenders to act for the Issuing Lender with respect thereto;
provided, however, that the Issuing Lender shall have all of the benefits and
immunities (i) provided to the Agent in this Article IX with respect to any acts
taken or omissions suffered by the Issuing Lender in connection with Letters of
Credit issued by it or proposed to be issued by it and the application and
agreements for letters of credit pertaining to the Letters of Credit as fully as
if the term "Agent" as used in this Article IX included the Issuing Lender with
respect to such acts or omissions, and (ii) as additionally provided herein with
respect to the Issuing Lender.

         (c) Each Lender hereby consents to and approves the Security Agreement
and the Collateral Assignment. By execution hereof, the Lenders agree to be
bound by the terms of the Security Agreement and the Collateral Assignment and
further authorize and direct the Collateral Agent to enter into the Security
Agreement and the Collateral Assignment on behalf of the Lenders.

         9.2      INDEMNIFICATION OF AGENT.

         Whether or not the transactions contemplated hereby are consummated,
the Lenders shall indemnify upon demand each Agent-Related Person (to the extent
not reimbursed by or on behalf of any Credit Party and without limiting the
obligation of any Credit Party to do so), pro rata, and hold harmless each
Agent-Related Person from and against any and all Indemnified Liabilities
incurred by it; provided, however, that no Lender shall be liable for the
payment to any Agent-Related Person of any portion of such Indemnified
Liabilities resulting from such Person's gross negligence or willful misconduct;
provided, however, that no action taken in accordance with the directions of the
Required Lenders shall be deemed to constitute gross negligence or willful
misconduct for purposes of this Section. Without limitation of the foregoing,
each Lender shall reimburse the Agent upon demand for its ratable share of any
costs or out-of-pocket expenses (including reasonable fees and costs of counsel)
incurred by the Agent in connection with the preparation, execution, delivery,
administration, modification, amendment or enforcement (whether through
negotiations, legal proceedings or otherwise) of, or legal advice in respect of
rights or responsibilities under, this Agreement, any other Loan Document, or
any document contemplated by or referred to herein, to the extent that the Agent
is not reimbursed for such expenses by or on behalf of the Borrower. The
undertaking in this Section shall survive termination of the Commitments, the
payment of all Obligations hereunder and the resignation or replacement of the
Agent.

         9.3      CREDIT DECISION; DISCLOSURE OF INFORMATION BY AGENT.

         Each Lender acknowledges that no Agent-Related Person has made any
representation or warranty to it, and that no act by the Agent hereinafter
taken, including any consent to and acceptance of any assignment or review of
the affairs of any Credit Party or any Affiliate thereof, shall be deemed to
constitute any representation or warranty by any Agent-Related Person to any
Lender as to any matter, including whether Agent-Related Persons have disclosed
material information in their possession. Each Lender represents to the Agent
that it has, independently

                                       73
<PAGE>
and without reliance upon any Agent-Related Person and based on such documents
and information as it has deemed appropriate, made its own appraisal of and
investigation into the business, prospects, operations, property, financial and
other condition and creditworthiness of the Credit Parties and their respective
Subsidiaries, and all applicable bank or other regulatory Laws relating to the
transactions contemplated hereby, and made its own decision to enter into this
Agreement and to extend credit to the Borrower and the other Credit Parties
hereunder. Each Lender also represents that it will, independently and without
reliance upon any Agent-Related Person and based on such documents and
information as it shall deem appropriate at the time, continue to make its own
credit analysis, appraisals and decisions in taking or not taking action under
this Agreement and the other Loan Documents, and to make such investigations as
it deems necessary to inform itself as to the business, prospects, operations,
property, financial and other condition and creditworthiness of the Borrower and
the other Credit Parties. Except for notices, reports and other documents
expressly required to be furnished to the Lenders by the Agent herein, the Agent
shall not have any duty or responsibility to provide any Lender with any credit
or other information concerning the business, prospects, operations, property,
financial and other condition or creditworthiness of any of the Credit Parties
or any of their respective Affiliates which may come into the possession of any
Agent-Related Person.

         9.4      NOTICE OF DEFAULT.

         The Agent shall not be deemed to have knowledge or notice of the
occurrence of any Default or Event of Default, except with respect to defaults
in the payment of principal, interest and fees required to be paid to the Agent
for the account of the Lenders, unless the Agent shall have received written
notice from a Lender or the Borrower referring to this Agreement, describing
such Default or Event of Default and stating that such notice is a "notice of
default." The Agent will notify the Lenders of its receipt of any such notice.
The Agent shall take such action with respect to such Default or Event of
Default as may be directed by the Required Lenders in accordance with Article
VIII; provided, however, that unless and until the Agent has received any such
direction, the Agent may (but shall not be obligated to) take such action, or
refrain from taking such action, with respect to such Default or Event of
Default as it shall deem advisable or in the best interest of the Lenders.

         9.5      FUNDING OF ADVANCES PURSUANT TO BORROWING NOTICES.

         Except to the extent otherwise provided herein, each Loan, each payment
or (subject to the terms of Section 2.13) prepayment of principal of any Loan,
each payment of interest on the Loans, each payment of commitment fees
referenced in Section 2.14, each reduction of the Total Commitments and each
conversion or extension of any Loan, shall be allocated pro rata among the
Lenders in accordance with the respective principal amounts of their outstanding
Loans.

         Furthermore, no Lender shall be responsible for the failure or delay by
any other Lender in its obligation to make its ratable share of a borrowing
hereunder; provided, however, that the failure of any Lender to fulfill its
obligations hereunder shall not relieve any other Lender of its obligations
hereunder. Unless the Borrower or any Lender has notified the Agent prior to the
date any payment is required to be made by it to the Agent hereunder, that the
Borrower or such Lender, as the case may be, will not make such payment, the
Agent may assume that the Borrower or

                                       74
<PAGE>
such Lender, as the case may be, has timely made such payment and may (but shall
not be so required to), in reliance thereon, make available a corresponding
amount to the Person entitled thereto. If and to the extent that such payment
was not in fact made to the Agent in immediately available funds, then:

             (a) if the Borrower failed to make such payment, each Lender shall
forthwith on demand repay to the Agent the portion of such assumed payment that
was made available to such Lender in immediately available funds, together with
interest thereon in respect of each day from and including the date such amount
was made available by the Agent to such Lender to the date such amount is repaid
to the Agent in immediately available funds, at the Federal Funds Rate from time
to time in effect; and

             (b) if any Lender failed to make such payment, such Lender shall
forthwith on demand pay to the Agent the amount thereof in immediately available
funds, together with interest thereon for the period from the date such amount
was made available by the Agent to the Borrower to the date such amount is
recovered by the Agent (the "Compensation Period") at a rate per annum equal to
the Federal Funds Rate from time to time in effect. If such Lender does not pay
such amount forthwith upon the Agent's demand therefor, the Agent may make a
demand therefor upon the Borrower, and the Borrower shall pay such amount to the
Agent, together with interest thereon for the Compensation Period at a rate per
annum equal to the rate of interest applicable to the applicable borrowing.

         Nothing herein shall be deemed to relieve any Lender from its
obligation to fulfill its Commitment or to prejudice any rights that the Agent
or the Borrower may have against any Lender as a result of any default by such
Lender hereunder. A notice of the Agent to any Lender with respect to any amount
owing under this Section shall be conclusive, absent manifest error.

         9.6      AGENT IN ITS INDIVIDUAL CAPACITY.

         Bank of America and its Affiliates may make loans to, issue letters of
credit for the account of, accept deposits from, acquire equity interests in and
generally engage in any kind of banking, trust, financial advisory, underwriting
or other business with each of the Credit Parties and their respective
Affiliates as though Bank of America were not the Agent or the Issuing Lender
hereunder and without notice to or consent of the Lenders. The Lenders
acknowledge that, pursuant to such activities, Bank of America or its Affiliates
may receive information regarding any Credit Party or its Affiliates (including
information that may be subject to confidentiality obligations in favor of such
Credit Party or such Affiliate) and acknowledge that the Agent shall be under no
obligation to provide such information to them. With respect to its Loans, Bank
of America shall have the same rights and powers under this Agreement as any
other Lender and may exercise such rights and powers as though it were not the
Agent or the Issuing Lender, and the terms "Lender" and "Lenders" include Bank
of America in its individual capacity.

                                       75
<PAGE>
         9.7      SUCCESSOR AGENT.

         The Agent may resign as the Agent upon 30 days' notice to the Lenders.
If the Agent resigns under this Agreement, the Required Lenders shall appoint
from among the Lenders a successor Agent for the Lenders which successor Agent
shall be consented to by the Borrower at all times other than during the
existence of an Event of Default (which consent of the Borrower shall not be
unreasonably withheld or delayed). If no successor Agent is appointed prior to
the effective date of the resignation of the Agent, the Agent may appoint, after
consulting with the Lenders and the Borrower, a successor Agent from among the
Lenders. Upon the acceptance of its appointment as successor Agent hereunder,
such successor Agent shall succeed to all the rights, powers and duties of the
retiring Agent and the term "Agent" shall mean such successor Agent and the
retiring Agent's appointment, powers and duties as the Agent shall be
terminated. After any retiring Agent's resignation hereunder as Agent, the
provisions of this Article IX shall inure to its benefit as to any actions taken
or omitted to be taken by it while it was the Agent under this Agreement. If no
successor Agent has accepted appointment as Agent by the date which is 30 days
following a retiring Agent's notice of resignation, the retiring Agent's
resignation shall nevertheless thereupon become effective and the Lenders shall
perform all of the duties of the Agent hereunder until such time, if any, as the
Required Lenders appoint a successor agent as provided for above.

         9.8      SHARING OF PAYMENTS, ETC.

         The Lenders agree among themselves that, in the event that any Lender
shall obtain payment in respect of any Loan, LOC Obligations or any other
obligation owing to such Lender under this Agreement through the exercise of a
right of setoff, banker's lien or counterclaim, or pursuant to a secured claim
under Section 506 of Title 11 of the United States Code or other security or
interest arising from, or in lieu of, such secured claim, received by such
Lender under any applicable bankruptcy, insolvency or other similar law or
otherwise, or by any other means, in excess of its pro rata share of such
payment as provided for in this Agreement, such Lender shall promptly purchase
from the other Lenders a Participation Interest in such Loans, LOC Obligations
and other Obligations so that the amount of the Obligations held by each of the
Lenders shall continue to equal their respective Pro Rata Shares and make such
other adjustments from time to time, as shall be equitable to the end that all
Lenders share such payment in accordance with their respective ratable shares as
provided for in this Agreement. The Lenders further agree among themselves that
if payment to a Lender obtained by such Lender through the exercise of a right
of setoff, banker's lien, counterclaim or other event as aforesaid shall be
rescinded or must otherwise be restored, the other Lenders who shared in the
benefit of such payment shall similarly arrange their interests in the
Obligations to reverse the distribution to them as to allow the originally
remitting Lender to refund such payment. The Borrower agrees that any Lender so
purchasing a share in the Obligations contemplated in this Section 9.8 may, to
the fullest extent permitted by law, exercise all rights of payment, including
setoff, banker's lien or counterclaim, with respect to such share in the
Obligations as fully as if such Lender were a holder of such Loan, LOC
Obligations or other obligation in such amount. Except as otherwise expressly
provided in this Agreement, if any Lender or the Agent shall fail to remit to
the Agent or any other Lender an amount payable by such Lender or the Agent to
the Agent or such other Lender pursuant to this Agreement on the date when such
amount is due,

                                       76
<PAGE>
such payments shall be made together with interest thereon for each date from
the date such amount is due until the date such amount is paid to the Agent or
such other Lender at a rate per annum equal to the Federal Funds Rate. If under
any applicable bankruptcy, insolvency or other similar law, any Lender receives
a secured claim in lieu of a setoff to which this Section 9.8 applies, such
Lender shall, to the extent practicable, exercise its rights in respect of such
secured claim in a manner consistent with the rights of the Lenders under this
Section 9.8 to share in the benefits of any recovery on such secured claim.

         9.9      PAYMENTS BETWEEN THE AGENT AND THE LENDERS.

                  9.9.1 Generally. All payments by the Agent to any Lender, and
         all payments by any Lender to the Agent, under the terms of this
         Agreement shall be made by wire transfer in immediately available funds
         to the receiving party's address specified for notices in this
         Agreement. If any of the Lenders fails to pay when due any sum payable
         to the Agent, then, except as otherwise provided in Section 9.5 hereof,
         such sum shall bear interest at the Federal Funds Rate, commencing on
         the date such payment was due and ending on, but excluding, the date
         such payment is made.

                  9.9.2 Allocation of Payments After Acceleration.
         Notwithstanding any other provisions of this Agreement to the contrary,
         after the occurrence and during the continuance of an Event of Default,
         all amounts collected or received by the Agent or any Lender on account
         of the Obligations or any other amounts outstanding under any of the
         Loan Documents or in respect of the Collateral shall be paid over or
         delivered as follows:

                  FIRST, to the payment of all reasonable out-of-pocket costs
         and expenses (including without limitation reasonable attorneys' fees)
         of the Agent in connection with enforcing the rights of the Lenders
         under the Loan Documents and any protective advances made by the Agent
         with respect to the Collateral under or pursuant to the terms of the
         Loan Documents;

                  SECOND, to payment of any fees owed to the Agent;

                  THIRD, to the payment of all reasonable out-of-pocket costs
         and expenses (including without limitation, reasonable attorneys' fees)
         of each of the Lenders in connection with enforcing its rights under
         the Loan Documents or otherwise with respect to the Obligations owing
         to such Lender;

                  FOURTH, to the payment of all of the Obligations consisting of
         accrued fees and interest;

                  FIFTH, to the payment of the outstanding principal amount of
         the Obligations (including the payment or cash collateralization of the
         outstanding LOC Obligations);

                  SIXTH, to all other Obligations and other obligations which
         shall have become due and payable under the Loan Documents or otherwise
         and not repaid pursuant to clauses "FIRST" through "FIFTH" above; and

                                       77
<PAGE>

                  SEVENTH, to the payment of the surplus, if any, to the
         Borrower or whoever else may be lawfully entitled to receive such
         surplus.

                  In carrying out the foregoing, (i) amounts received shall be
         applied in the numerical order provided until exhausted prior to
         application to the next succeeding category; (ii) each of the Lenders
         shall receive an amount equal to its pro rata share (based on the
         proportion that the then outstanding Loans and LOC Obligations held by
         such Lender bears to the aggregate then outstanding Loans and LOC
         Obligations) of amounts available to be applied pursuant to clauses
         "THIRD", "FOURTH", "FIFTH" and "SIXTH" above; and (iii) to the extent
         that any amounts available for distribution pursuant to clause "FIFTH"
         above are attributable to the issued but undrawn amount of outstanding
         Letters of Credit, such amounts shall be held by the Agent in a cash
         collateral account and applied (A) first, to reimburse the Issuing
         Lender from time to time for any drawings under such Letters of Credit
         and (B) then, following the expiration of all Letters of Credit, to all
         other obligations of the types described in clauses "FIFTH" and "SIXTH"
         above in the manner provided in this Section 9.9.2.

         9.10     ASSIGNMENTS AND PARTICIPATIONS.

                  9.10.1 Successors and Assigns. The provisions of this
         Agreement shall be binding upon and inure to the benefit of the parties
         hereto and their respective successors and assigns permitted hereby,
         except that the Borrower may not assign or otherwise transfer any of
         its rights or obligations hereunder without the prior written consent
         of each Lender (and any attempted assignment or transfer by the
         Borrower without such consent shall be null and void). Nothing in this
         Agreement, expressed or implied, shall be construed to confer upon any
         Person (other than the parties hereto, their respective successors and
         assigns permitted hereby and, to the extent expressly contemplated
         hereby, the Indemnitees) any legal or equitable right, remedy or claim
         under or by reason of this Agreement.

                  9.10.2 Eligible Assignees. Any Lender may assign to one or
         more Eligible Assignees all or a portion of its rights and obligations
         under this Agreement (including all or a portion of its Commitment and
         the Loans (including for purposes of this Section 9.10.2,
         participations in Swingline Loans) at the time owing to it); provided
         that (i) except in the case of an assignment of the entire remaining
         amount of the assigning Lender's Commitment and the Loans at the time
         owing to it or in the case of an assignment to a Lender or an Affiliate
         of a Lender or an Approved Fund with respect to a Lender, the aggregate
         amount of the Commitment (which for this purpose includes Loans
         outstanding thereunder) subject to each such assignment, determined as
         of the date the Assignment and Acceptance with respect to such
         assignment is delivered to the Agent, shall not be less than $2,500,000
         unless each of the Agent and, so long as no Event of Default has
         occurred and is continuing, the Borrower otherwise consents (each such
         consent not to be unreasonably withheld or delayed), (ii) each partial
         assignment shall be made as an assignment of a proportionate part of
         all the assigning Lender's rights and obligations under this Agreement
         with respect to the Loans or the Commitment assigned,

                                       78
<PAGE>
         except that this clause (ii) shall not apply to rights in respect of
         outstanding Swingline Loans, (iii) each such assignment by a Lender of
         any portion of its Commitment and its Revolving Credit Loans shall be
         accompanied by an assignment of the same percentage of such Lender's
         364-Day Commitment and its 364-Day Loans and (iv) the parties to each
         assignment shall execute and deliver to the Agent an Assignment and
         Acceptance, together with a processing and recordation fee of $3,500.
         Subject to acceptance and recording thereof by the Agent pursuant to
         subsection (c) of this Section, from and after the effective date
         specified in each Assignment and Acceptance, the Eligible Assignee
         thereunder shall be a party hereto and, to the extent of the interest
         assigned by such Assignment and Acceptance, have the rights and
         obligations of a Lender under this Agreement, and the assigning Lender
         thereunder shall, to the extent of the interest assigned by such
         Assignment and Acceptance, be released from its obligations under this
         Agreement (and, in the case of an Assignment and Acceptance covering
         all of the assigning Lender's rights and obligations under this
         Agreement, such Lender shall cease to be a party hereto but shall
         continue to be entitled to the benefits of Sections 5.17 and 10.25).
         Upon request, the Borrower (at its expense) shall execute and deliver
         new or replacement Notes to the assigning Lender and the assignee
         Lender. Any assignment or transfer by a Lender of rights or obligations
         under this Agreement that does not comply with this subsection shall be
         treated for purposes of this Agreement as a sale by such Lender of a
         participation in such rights and obligations in accordance with Section
         9.10.4.

                  9.10.3 Register. The Agent, acting solely for this purpose as
         an agent of the Borrower, shall maintain at its office in Chicago,
         Illinois a copy of each Assignment and Acceptance delivered to it and a
         register for the recordation of the names and addresses of the Lenders,
         and the Commitments of, and principal amount of the Loans owing to,
         each Lender pursuant to the terms hereof from time to time (the
         "Register"). The entries in the Register shall be conclusive, and the
         Borrower, the Agent and the Lenders may treat each Person whose name is
         recorded in the Register pursuant to the terms hereof as a Lender
         hereunder for all purposes of this Agreement, notwithstanding notice to
         the contrary. The Register shall be available for inspection by the
         Borrower and any Lender, at any reasonable time and from time to time
         upon reasonable prior notice.

                  9.10.4 Participations. Any Lender may, without the consent of,
         or notice to, the Borrower or the Agent, sell participations to one or
         more banks or other entities (a "Participant") in all or a portion of
         such Lender's rights and/or obligations under this Agreement (including
         all or a portion of its Commitment and/or the Loans (including such
         Lender's participations in Swingline Loans) owing to it); provided that
         (i) such Lender's obligations under this Agreement shall remain
         unchanged, (ii) such Lender shall remain solely responsible to the
         other parties hereto for the performance of such obligations and (iii)
         the Borrower, the Agent and the other Lenders shall continue to deal
         solely and directly with such Lender in connection with such Lender's
         rights and obligations under this Agreement. Any agreement or
         instrument pursuant to which a Lender sells such a participation shall
         provide that such Lender shall retain the sole right to enforce this
         Agreement and to approve any amendment, modification or waiver of any
         provision of this Agreement; provided that such agreement or instrument
         may provide that such Lender will not, without the consent of the
         Participant, agree to any

                                       79
<PAGE>
         amendment, waiver or other modification that would (i) postpone any
         date upon which any payment of money is scheduled to be paid to such
         Participant, (ii) reduce the principal, interest, fees or other amounts
         payable to such Participant or (iii) release all or substantially all
         of the Guarantors from their obligations under the Loan Documents.
         Subject to Section 9.10.5, the Borrower agrees that each Participant
         shall be entitled to the benefits of Sections 2.7, 2.8, 2.9 and 9.13 to
         the same extent as if it were a Lender and had acquired its interest by
         assignment pursuant to Section 9.10.2. To the extent permitted by law,
         each Participant also shall be entitled to the benefits of Section
         10.23 as though it were a Lender, provided such Participant agrees to
         be subject to Section 9.8 as though it were a Lender.

                  9.10.5 A Participant shall not be entitled to receive any
         greater payment under Section 2.7, 2.8 and 2.9 than the applicable
         Lender would have been entitled to receive with respect to the
         participation sold to such Participant, unless the sale of the
         participation to such Participant is made with the Borrower's prior
         written consent. A Participant that would be a Foreign Lender if it
         were a Lender shall not be entitled to the benefits of Section 9.13
         unless the Borrower is notified of the participation sold to such
         Participant and such Participant agrees, for the benefit of the
         Borrower, to comply with Section 9.13.4 as though it were a Lender.

                  9.10.6 Any Lender may at any time pledge or assign a security
         interest in all or any portion of its rights under this Agreement
         (including under its Notes, if any) to secure obligations of such
         Lender, including any pledge or assignment to secure obligations to a
         Federal Reserve Bank; provided that no such pledge or assignment shall
         release a Lender from any of its obligations hereunder or substitute
         any such pledgee or assignee for such Lender as a party hereto.

                  9.10.7 If the consent of the Borrower to an assignment or to
         an Eligible Assignee is required hereunder (including a consent to an
         assignment which does not meet the minimum assignment threshold
         specified in clause (i) of the proviso to the first sentence of Section
         9.10.2, the Borrower shall be deemed to have given its consent five
         Business Days after the date notice thereof has been delivered by the
         assigning Lender (through the Agent) unless such consent is expressly
         refused by the Borrower prior to such fifth Business Day.

                  9.10.8 Notwithstanding anything to the contrary contained
         herein, if at any time Bank of America assigns all of its Commitment
         and Loans pursuant to subsection (b) above, Bank of America may, (i)
         upon 30 days' notice to the Borrower and the Lenders resign as Issuing
         Lender and/or (ii) upon 5 Business Days' notice to the Borrower, resign
         as Swingline Lender. In the event of any such resignation as Issuing
         Lender or Swingline Lender, the Borrower shall be entitled to appoint
         from among the Lenders a successor Issuing Lender or Swingline Lender
         hereunder; provided, however, that no failure by the Borrower to
         appoint any such successor shall affect the resignation of Bank of
         America as Swingline Lender, as the case may be. Bank of America shall
         retain all the rights and obligations of the Issuing Lender hereunder
         with respect to all Letters of Credit outstanding as of the effective
         date of its resignation as Issuing Lender and all LOC

                                       80
<PAGE>
         Obligations with respect thereto (including the right to require the
         Lenders to make Revolving Credit Loans or fund their Participation
         Interests pursuant to Section 2.17). If Bank of America resigns as
         Swingline Lender, it shall retain all the rights of the Swingline
         Lender provided for hereunder with respect to Swingline Loans made by
         it and outstanding as of the effective date of such resignation,
         including the right to require the Lenders to make Revolving Credit
         Loans or fund participations in outstanding Swingline Loans pursuant to
         Section 2.16.9.

         9.11     PROCEDURES FOR NOTICES AND APPROVALS.

         All notices given among the Lenders and the Agent with respect to this
Agreement or the other Loan Documents shall be given in the manner provided in
this Agreement.

         9.12     OTHER RELATIONSHIPS WITH THE BORROWER.

         Each Lender is free to engage in deposit relationships and other
business relationships with the Borrower Entities, provided that such
relationship does not violate any restriction set forth in this Agreement.

         9.13     TAXES.

                  9.13.1 Payments. Any and all payments by the Borrower to or
         for the account of any Lender or the Agent hereunder or under any other
         Loan Document shall be made free and clear of and without deduction for
         any and all present or future taxes, duties, levies, imposts,
         deductions, charges or withholdings, and all liabilities with respect
         thereto, excluding, in the case of each Lender and the Agent, taxes
         imposed on or measured by its income or capital, and franchise taxes
         imposed on it, by the jurisdiction under the laws of which such Lender
         (or its Applicable Lending Office) or the Agent (as the case may be) is
         organized or maintains a lending office or any political subdivision
         thereof (all such non-excluded taxes, duties, levies, imposts,
         deductions, charges, withholdings, and liabilities being hereinafter
         referred to as "Taxes"). If the Borrower shall be required by law to
         deduct any Taxes from or in respect of any sum payable under this
         Agreement or any other Loan Document to any Lender or the Agent (except
         as permitted under subsection (e) below), (i) the sum payable shall be
         increased as necessary so that after making all required deductions
         (including deductions applicable to additional sums payable under this
         Section 9.13) such Lender or the Agent receives an amount equal to the
         sum it would have received had no such deductions been made, (ii) the
         Borrower shall make such deductions, (iii) the Borrower shall pay the
         full amount deducted to the relevant taxation authority or other
         authority in accordance with applicable law, and (iv) the Borrower
         shall furnish to the Agent, at its address referred to in Section 10.1,
         the original or a certified copy of a receipt evidencing payment
         thereof.

                  9.13.2 Other Taxes. In addition, the Borrower agrees to pay
         any and all present or future stamp or documentary taxes, property
         taxes and any other excise or similar taxes or charges or levies which
         arise from any payment made under this Agreement or any other Loan
         Document or from the execution or delivery of, or otherwise with
         respect

                                       81
<PAGE>
         to, this Agreement or any other Loan Document (hereinafter referred to
         as "Other Taxes").

                  9.13.3 Indemnity. The Borrower agrees to indemnify each Lender
         and the Agent for the full amount of Taxes and Other Taxes (including,
         without limitation, any Taxes or Other Taxes imposed or asserted by any
         jurisdiction on amounts payable under this Section 9.13) paid by such
         Lender or the Agent (as the case may be) and any liability (including
         penalties, interest, and expenses) arising therefrom or with respect
         thereto.

                  9.13.4 Foreign Lender. Each Lender that is not a United States
         person under Section 7701(a)(30) of the Code (a "Foreign Lender"), on
         or prior to the date of its execution and delivery of this Agreement in
         the case of each Lender listed on the signature pages hereof and on or
         prior to the date on which it becomes a Lender in the case of each
         other Lender, and from time to time thereafter upon the expiration or
         invalidity of any previously issued certificate or if requested in
         writing by the Borrower or the Agent (but only so long as such Lender
         remains lawfully able to do so), shall provide the Borrower and the
         Agent with (i) a properly completed and duly executed Internal Revenue
         Service Form W-8 BEN or W-8 ECI, as appropriate, or any successor form
         prescribed by the Internal Revenue Service, certifying that such Lender
         is entitled to benefits under an income tax treaty to which the United
         States is a party which reduces to zero the rate of withholding tax on
         payments of interest or certifying that the income receivable pursuant
         to this Agreement is effectively connected with the conduct of a trade
         or business in the United States, and (ii) any other form or
         certificate required by any taxing authority (including any certificate
         required by Sections 871(h) and 881(c) of the Internal Revenue Code),
         certifying that such Lender is entitled to an exemption from
         withholding tax on payments pursuant to this Agreement or any of the
         other Loan Documents. Each Lender that is a United States person shall
         submit a properly completed and duly executed Internal Revenue Service
         Form W-9, or any successor form prescribed by the Internal Revenue
         Service, certifying that it is exempt from backup withholding.

                  9.13.5 Form. For any period with respect to which a Lender has
         failed to provide the Borrower and the Agent with the appropriate form
         pursuant to Section 9.13.4 (unless such failure is due to a change in
         treaty, law, or regulation occurring subsequent to the date on which a
         form originally was required to be provided), such Lender shall not be
         entitled to indemnification under Section 9.13.1 or 9.13.2 with respect
         to Taxes imposed by the United States; provided, however, that should a
         Lender, which is otherwise exempt from withholding tax, become subject
         to Taxes because of its failure to deliver a form required hereunder,
         the Borrower shall take such steps as such Lender shall reasonably
         request to assist such Lender to recover such Taxes.

                  9.13.6 Applicable Lending Office. If the Borrower is required
         to pay additional amounts to or for the account of any Lender pursuant
         to this Section 9.13, then such Lender will agree to use reasonable
         efforts to change the jurisdiction of its Applicable Lending Office so
         as to eliminate or reduce any such additional payment which may
         thereafter accrue if such change, in the judgment of such Lender, is
         not otherwise disadvantageous to such Lender. In the event that any
         Lender receives a refund or credit

                                       82
<PAGE>
         in respect of Taxes for which such party has received an
         indemnification from the Borrower under Section 9.13.1 or 9.13.2, such
         Lender shall promptly pay to the Borrower an amount that such Lender
         reasonably determines is equal to the net tax benefit obtained by such
         Lender. Nothing contained in this Section shall require any Lender to
         claim a refund or credit, and nothing contained in this Section shall
         require a Lender to disclose or detail the basis of its calculation of
         the amount of any tax benefit or any other amount.

                  9.13.7 Evidence of Payment. Within thirty (30) days after the
         date of any payment of Taxes, the Borrower shall furnish to the Agent
         the original or a certified copy of a receipt evidencing such payment.

                  9.13.8 Survival. Without prejudice to the survival of any
         other agreement of the Borrower hereunder, the agreements and
         obligations of the Borrower contained in this Section 9.13 shall
         survive the repayment of the Loans and other obligations under the Loan
         Documents and the termination of the Commitments hereunder.

         9.14     DELEGATION OF DUTIES.

         The Agent may execute any of its duties under this Agreement or any
other Loan Document by or through agents, employees or attorneys-in-fact and
shall be entitled to advice of counsel and other consultants or experts
concerning all matters pertaining to such duties. The Agent shall not be
responsible for the negligence or misconduct of any agent or attorney-in-fact
that it selects in the absence of gross negligence or willful misconduct.

         9.15     LIABILITY OF AGENT.

         No Agent-Related Person shall (a) be liable for any action taken or
omitted to be taken by any of them under or in connection with this Agreement or
any other Loan Document or the transactions contemplated hereby (except for its
own gross negligence or willful misconduct in connection with its duties
expressly set forth herein), or (b) be responsible in any manner to any Lender
or participant for any recital, statement, representation or warranty made by
any Credit Party or any officer thereof, contained herein or in any other Loan
Document, or in any certificate, report, statement or other document referred to
or provided for in, or received by the Agent under or in connection with, this
Agreement or any other Loan Document, or the validity, effectiveness,
genuineness, enforceability or sufficiency of this Agreement or any other Loan
Document, or for any failure of any Credit Party or any other party to any Loan
Document to perform its obligations hereunder or thereunder. No Agent-Related
Person shall be under any obligation to any Lender or participant to ascertain
or to inquire as to the observance or performance of any of the agreements
contained in, or conditions of, this Agreement or any other Loan Document, or to
inspect the Facilities, books or records of any Credit Party or any Affiliate
thereof.

         9.16     RELIANCE BY AGENT.

         (a) The Agent shall be entitled to rely, and shall be fully protected
in relying, upon any writing, communication, signature, resolution,
representation, notice, consent, certificate,

                                       83
<PAGE>
affidavit, letter, telegram, facsimile, telex or telephone message, statement or
other document or conversation believed by it to be genuine and correct and to
have been signed, sent or made by the proper Person or Persons, and upon advice
and statements of legal counsel (including counsel to any Credit Party),
independent accountants and other experts selected by the Agent. The Agent shall
be fully justified in failing or refusing to take any action under any Loan
Document unless it shall first receive such advice or concurrence of the
Required Lenders as it deems appropriate and, if it so requests, it shall first
be indemnified to its satisfaction by the Lenders against any and all liability
and expense which may be incurred by it by reason of taking or continuing to
take any such action. The Agent shall in all cases be fully protected in acting,
or in refraining from acting, under this Agreement or any other Loan Document in
accordance with a request or consent of the Required Lenders or all the Lenders,
if required hereunder, and such request and any action taken or failure to act
pursuant thereto shall be binding upon all the Lenders and participants. Where
this Agreement expressly permits or prohibits an action unless the Required
Lenders otherwise determine, the Agent shall, and in all other instances, the
Agent may, but shall not be required to, initiate any solicitation for the
consent or a vote of the Lenders.

         (b) For purposes of determining compliance with the conditions
specified in Section 3.1, each Lender that has signed this Agreement shall be
deemed to have consented to, approved or accepted or to be satisfied with, each
document or other matter either sent by the Agent to such Lender for consent,
approval, acceptance or satisfaction, or required thereunder to be consented to
or approved by or acceptable or satisfactory to a Lender.

         9.17     OTHER AGENTS; LEAD MANAGERS.

         None of the Lenders identified on the facing page or signature pages of
this Agreement as a "syndication agent," "documentation agent," "co-agent" or
"lead manager" shall have any right, power, obligation, liability,
responsibility or duty under this Agreement other than those applicable to all
Lenders as such. Without limiting the foregoing, none of the Lenders so
identified shall have or be deemed to have any fiduciary relationship with any
Lender. Each Lender acknowledges that it has not relied, and will not rely, on
any of the Lenders so identified in deciding to enter into this Agreement or in
taking or not taking action hereunder.

         All provisions of this Agreement relating to Obligations shall apply

right of the Agent or any Lender to serve process in any other manner permitted
by law or to commence legal proceedings or to otherwise proceed against any
Credit Party in any other jurisdiction.

         10.6     NOT PARTNERS; NO THIRD PARTY BENEFICIARIES.

         The relationship of the Lenders and the Borrower is that of lenders and
borrower only, and neither is a fiduciary, partner or joint venturer of the
other for any purpose. This Agreement has been executed for the sole benefit of
the Lenders, and no third party is authorized to rely upon the Lenders' rights
or duties hereunder.

         10.7     NO RELIANCE ON LENDERS' ANALYSIS.

         The Borrower acknowledges and represents that, in connection with the
Obligations, the Borrower has not relied upon any financial projection, budget,
assessment or other analysis by the Lenders or the Agent upon any representation
by the Lenders as to the risks, benefits or prospects of the Borrower's Line of
Business activities or present or future capital needs

                                       86
<PAGE>
incidental thereto, all such considerations having been examined fully and
independently by the Borrower.

         10.8     NO MARSHALING OF ASSETS.

         The Lenders and the Agent may proceed against collateral securing the
Obligations and against parties liable therefor in such order as they may elect,
and neither the Borrower nor any surety or guarantor for the Borrower nor any
creditor of the Borrower shall be entitled to require the Lenders or the Agent
to marshal assets. The benefit of any rule of law or equity to the contrary is
hereby expressly waived.

         10.9     IMPAIRMENT OF COLLATERAL.

         The Lenders or the Agent (acting as permitted under this Agreement) may

therefor. The defenses of impairment of collateral and impairment of recourse
and any requirement of diligence in collecting the Obligations are hereby
waived.

         10.10    BUSINESS DAYS.

         If any payment date under the Obligations falls on a day that is not a
Business Day, or if the last day of any notice period falls on such a day, the
payment shall be due and the notice period shall end on the next following
Business Day.

         10.11    STANDARD OF CARE; LIMITATION OF DAMAGES.

         The Lenders and the Agent shall be liable to the Borrower only for
matters arising from this Agreement or otherwise related to the Obligations

misconduct, and not for matters arising from their ordinary negligence, and
liability for all other matters is hereby waived. The Lenders and the Agent
shall not in any event be liable to the Borrower for special or consequential
damages arising from this Agreement or otherwise related to the Obligations.

         10.12    INCORPORATION OF SCHEDULES.

         All Schedules and Exhibits referred to in this Agreement are
incorporated herein by this reference.

         10.13    INDULGENCE NOT WAIVER.

         The Lenders' or the Agent's indulgence in the existence of a default
hereunder or any other departure from the terms of this Agreement shall not

demand strict compliance with this Agreement.

         10.14    CUMULATIVE REMEDIES.

         10.15    AMENDMENT AND WAIVERS.

         Neither this Agreement nor any other Loan Document nor any of the terms
hereof or thereof may be amended, changed, waived, discharged or terminated
unless such amendment, change, waiver, discharge or termination is in writing
entered into by, or approved in writing by, the Required Lenders and the
Borrower, provided, however, that:

         (a) without the consent of each Lender affected thereby, no such
amendment, change of waiver shall:

                  (i) extend the final maturity of any Loan, or extend or waive
         the principal payment of any Loan, or any portion thereof;

                  (ii) reduce the rate or extend the time of payment of interest
         (other than as a result of waiving the applicability of any
         post-default increase in interest rates) thereon or fees hereunder;

                  (iii) reduce or waive the principal amount of any Loan (except
         for the waiver of a mandatory prepayment required by Section 2.13
         hereof);

                  (iv) increase the Commitment of a Lender over the amount
         thereof in effect (it being understood and agreed that a waiver of any
         Default or Event of Default or mandatory reduction in the Commitments
         shall not constitute a change in the terms of any Commitment of any
         Lender);

                  (v)      release all or substantially all of the Collateral;

                  (vi) release the Borrower or substantially all of the
         Guarantors from its or their obligations under the Loan Documents;

                  (vii) amend, modify or waive any provision of this Section
         10.16 or Section 2.7, 2.8, 2.9, 5.17, 9.8, 9.10, 9.13, 10.23, 10.24, or
         10.25.

                  (viii) reduce any percentage specified in, or otherwise
         modify, the definition of Required Lenders; or

                  (ix) consent to the assignment or transfer by the Borrower or
         all or substantially all of the Guarantors of any of its or their
         rights and obligations under (or in respect of) the Loan Documents
         except as permitted thereby;

                                       88
<PAGE>
         (b) without the consent of the Agent, no provision of Article IX may be
amended, changed, waived, discharged or terminated;

         (c) without the consent of the Swingline Lender, no provision of
Section 2.16 may be amended, changed, waived, discharged or terminated; and

         (d) without the consent of the Issuing Lender, no provision of Section
2.17 or Section 2.15.3 may be amended, changed, waived, discharged or terminated
in a manner that is adverse to the Issuing Lender.

         Notwithstanding the fact that the consent of all the Lenders is
required in certain circumstances as set forth above, (x) each Lender is
entitled to vote as such Lender sees fit on any bankruptcy reorganization plan
that affects the Loans, and each Lender acknowledges that the provisions of
Section 1126(c) of the Bankruptcy Code supersedes the unanimous consent
provisions set forth herein and (y) the Required Lenders may consent to allow a
Credit Party to use cash collateral in the context of a bankruptcy or insolvency
proceeding.

         10.16    ENTIRE AGREEMENT.

         This Agreement and the other written agreements among the Borrower, the
Lenders and the Agent represent the entire agreement between the parties
concerning the subject matter hereof, and supersede all prior agreements and
understandings, oral or written, if any, including any commitment letters or
correspondence relating to the Credit Documents or the transactions contemplated
herein and. Provided, if there is a conflict between this Agreement and any
other document executed contemporaneously herewith with respect to the
Obligations, the provision in this Agreement shall control.

         10.17    SEVERABILITY.

         Should any provision of any of the Loan Documents be declared illegal,
invalid or unenforceable for any reason, such provision shall be fully severable
and the remaining provisions hereof shall remain in full force and effect and
shall be construed without giving effect to the illegal, invalid or
unenforceable provisions.

         10.18    TIME OF ESSENCE.

         Time is of the essence of this Agreement, and all dates and time
periods specified herein shall be strictly observed.

         10.20    CAPTIONS NOT CONTROLLING.

         TO THE EXTENT PERMITTED BY LAW, EACH OF THE AGENT, THE LENDERS AND EACH
OF THE CREDIT PARTIES HEREBY IRREVOCABLY WAIVES ALL RIGHT TO TRIAL BY JURY IN
ANY ACTION, PROCEEDING OR COUNTERCLAIM ARISING OUT OF OR RELATING TO THIS
AGREEMENT, ANY OF THE OTHER LOAN DOCUMENTS OR THE TRANSACTIONS CONTEMPLATED
HEREBY.

         10.22    FACSIMILE SIGNATURES.

         This Agreement may be executed by facsimile signatures, and shall be

pages executed by all parties hereto; provided, however, that all parties shall
deliver original executed documents to the Agent promptly following the
execution hereof.

         10.23    RIGHT OF SET-OFF; ADJUSTMENTS.

         Upon the occurrence and during the continuance of any Event of Default,
each Lender (and each of its Affiliates) is hereby authorized at any time and
from time to time, to the fullest extent permitted by law, to set off and apply
any and all deposits (general or special, time or demand, provisional or final)
at any time held and other indebtedness at any time owing by such Lender (or any
of its Affiliates) to or for the credit or the account of any Credit Party
against any and all of the obligations of such Person now or hereafter existing
under this Agreement, under the Notes, under any other Loan Document or
otherwise, irrespective of whether such Lender shall have made any demand
hereunder or thereunder and although such obligations may be unmatured. Each
Lender agrees promptly to notify any affected Credit Party after any such
set-off and application made by such Lender; provided, however, that the failure
to give such notice shall not affect the validity of such set-off and
application. The rights of each Lender under this Section 10.23 are in addition
to other rights and remedies (including, without limitation, other rights of
set-off) that such Lender may have.

         10.24    CONFIDENTIALITY.

         Each of the Agent and the Lenders agrees to maintain the
confidentiality of the Information (as defined below), except that Information
may be disclosed (a) to its and its Affiliates' directors, officers, employees
and agents, including accountants, legal counsel and other advisors (it being
understood that the Persons to whom such disclosure is made will be informed of
the confidential nature of such Information and instructed to keep such
Information confidential); (b) to the extent requested by any regulatory
authority; (c) to the extent required by applicable laws or regulations or by
any subpoena or similar legal process; (d) to any other party to this Agreement;
(e) in connection with the exercise of any remedies hereunder or any

                                       90
<PAGE>
suit, action or proceeding relating to this Agreement or the enforcement of
rights hereunder; (f) subject to an agreement containing provisions
substantially the same as those of this Section, to (i) any Eligible Assignee of
or Participant in, or any prospective Eligible Assignee of or Participant in,
any of its rights or obligations under this Agreement or (ii) any direct or
indirect contractual counterparty or prospective counterparty (or such
contractual counterparty's or prospective counterparty's professional advisor)
to any credit derivative transaction relating to obligations of the Borrower;
(g) with the consent of the Borrower; (h) to the extent such Information (i)
becomes publicly available other than as a result of a breach of this Section or
(ii) becomes available to the Agent or any Lender on a nonconfidential basis
from a source other than the Borrower; or (i) to the National Association of
Insurance Commissioners or any other similar organization or any nationally
recognized rating agency that requires access to information about a Lender's or
its Affiliates' investment portfolio in connection with ratings issued with
respect to such Lender or its Affiliates. For the purposes of this Section,
"Information" means all information received from the Borrower relating to the
Borrower or its business, other than any such information that is available to
the Agent or any Lender on a nonconfidential basis prior to disclosure by the
Borrower; provided that, in the case of information received from the Borrower
after the date hereof, such information is clearly identified in writing at the
time of delivery as confidential. Any Person required to maintain the
confidentiality of Information as provided in this Section shall be considered
to have complied with its obligation to do so if such Person has exercised the
same degree of care to maintain the confidentiality of such Information as such
Person would accord to its own confidential information.

         10.25    NO WAIVER; REMEDIES CUMULATIVE.

         No failure or delay on the part of the Agent or any Lender in
exercising any right, power or privilege hereunder or under any other Loan
Document and no course of dealing between the Agent or any Lender and any of the
Credit Parties shall operate as a waiver thereof; nor shall any single or
partial exercise of any right, power or privilege hereunder or under any other
Loan Document preclude any other or further exercise thereof or the exercise of
any other right, power or privilege hereunder or thereunder. The rights and
remedies provided herein are cumulative and not exclusive of any rights or
remedies which the Agent or any Lender would otherwise have. No notice to or
demand on any Credit Party in any case shall entitle the Borrower or any other
Credit Party to any other or further notice or demand in similar or other
circumstances or constitute a waiver of the rights of the Agent or the Lenders
to any other or further action in any circumstances without notice or demand.

         10.26    SURVIVAL.

         All indemnities set forth herein, including, without limitation, in

                                 SWINGLINE NOTE

$10,000,000                                                    ___________, 2002

         FOR VALUE RECEIVED, Renal Care Group, Inc., a Delaware corporation (the
"Borrower"), promises to pay to the order of BANK OF AMERICA, N.A. (the
"Swingline Lender"), the sum of Ten Million and No/100 Dollars ($10,000,000.00),
or as much thereof as may be outstanding from time to time, together with
interest thereon as provided in that Second Amended and Restated Loan Agreement
dated as of July ___, 2002 among the Borrower, the Lenders party thereto and
Bank of America, N.A. (formerly NationsBank of Tennessee, N.A.), as agent (the
"Agent") (as renewed, extended, amended, restated or modified from time to time,
the "Loan Agreement"). All capitalized terms used herein but not otherwise
defined shall have the meanings ascribed to such terms in the Loan Agreement.

         This Note evidences the Swingline Loan. Reference is made to the Loan
Agreement for the terms of payment of principal and interest hereunder, for a
description of the rights of the Agent, to enforce this Note, and for additional
provisions regarding additional payments, prepayment, draws and other terms and
conditions applicable to the indebtedness evidenced by this Note. As provided in
the Loan Agreement, (i) all remaining principal, interest and expenses
outstanding hereunder or under the Loan Agreement shall become finally due on
the Maturity Date, and (ii) the sum of the outstanding principal balance
hereunder plus the outstanding principal balance of the Revolving Credit Loans
plus the aggregate principal amount of LOC Obligations outstanding may not
exceed $100,000,000 in the aggregate at any time.

         As provided in the Loan Agreement, interest hereunder shall be
calculated based upon a 360-day year and actual days elapsed. As also provided
further in the Loan Agreement, the interest rate required hereby shall not
exceed the maximum rate permissible under applicable law, and any amounts paid
in excess of such rate shall be applied to reduce the principal amount hereof or
shall be refunded to the Borrower, at the option of the Swingline Lender.

         Subject to the provisions of the Loan Agreement, the Borrower may
borrow, repay and reborrow amounts hereunder from time to time, provided that
the Borrower is not in default hereunder or under the Loan Agreement and
provided that all conditions to the Swingline Lender's obligation to fund
advances as set forth in the Loan Agreement are satisfied. The Swingline Lender
shall have no liability for its refusal to advance funds hereunder following a
determination that any condition precedent to the making of an advance has not
been satisfied.

         The Swingline Lender's records of the amounts advanced hereunder shall
be prima facie evidence thereof, absent manifest error.

         The occurrence of an Event of Default under the Loan Agreement shall
constitute an Event of Default under this Note.

                                       1
<PAGE>

         Upon the occurrence of an Event of Default, the Swingline Lender may,
at its option and without notice (except as provided in the Loan Agreement), and
acting through the Agent in accordance with the Loan Agreement, declare all
principal and interest provided for under this Note, to be presently due and
payable, and may enforce any remedies available to the Swingline Lender under
any documents securing or evidencing debts of the Borrower to the Swingline
Lender. Upon an Event of Default, the remaining unpaid principal balance of the
indebtedness evidenced hereby and all expenses due the Swingline Lender shall
bear interest at the Default Rate, as defined in the Loan Agreement.

         All amounts received for payment of this Note shall be applied in
accordance with the Loan Agreement.

         The Borrower and all sureties, guarantors, endorsers and other parties
to this instrument hereby consent to any and all renewals, waivers,
modifications, or extensions of time (of any duration) that may be granted by
the Swingline Lender with respect to this Note and severally waive demand,
presentment, protest, notice of dishonor, and all other notices that might
otherwise be required by law, except as set forth in the Loan Agreement. All
parties hereto waive the defense of impairment of collateral and all other
defenses of suretyship, if applicable.

         The Borrower's performance under this Note is secured by various
property, as described in the Loan Agreement.

         The Borrower and all sureties, guarantors, endorsers and other parties
hereto agree to pay reasonable attorneys' fees and all court and other costs
that the Swingline Lender may incur in the course of efforts to collect the debt
evidenced hereby or to protect the Swingline Lender's interest in any collateral
securing the same, to the extent permitted by the Loan Agreement.

         The validity and construction of this Note shall be determined
according to the laws of Georgia applicable to contracts executed and performed
within that state and applicable federal law. If any provision of this Note
should for any reason be invalid or unenforceable, the remaining provisions
hereof shall remain in full effect.

                                    SECTION 1
                                   DEFINITIONS

         1.1      CERTAIN DEFINITIONS.

         Unless otherwise defined herein, capitalized terms used herein shall

<PAGE>

         Bankruptcy Code), and (ii) the present and future obligations of the

                  "Guarantors" means the collective reference to each of the

                                    GUARANTY

         2.1      THE GUARANTY.

         Each Guarantor hereby guarantees to each Lender, each Affiliate of a
Lender that enters into a Hedging Agreement, and the Agent as hereafter
provided, as primary obligor and not as surety, the prompt payment of the
Guaranteed Obligations in full when due (whether at stated maturity, as a
mandatory prepayment, by acceleration, as a mandatory cash collateralization or
otherwise) strictly in accordance with the terms thereof. Each Guarantor hereby
further agrees that if any of the Guaranteed Obligations are not paid in full
when due (whether at stated maturity, as a mandatory prepayment, by
acceleration, as a mandatory cash collateralization or otherwise), the
Guarantors will promptly pay the same, without any demand or notice whatsoever
(except for any such notice required by the Loan Agreement), and that in the
case of any extension of time of payment or renewal of any of the Guaranteed
Obligations, the same will be promptly paid in full when due (whether at
extended maturity, as a mandatory prepayment, by acceleration, as a mandatory
cash collateralization or otherwise) in accordance with the terms of such
extension or renewal.

         Notwithstanding any provision to the contrary contained herein or in
any other of the Loan Documents or Hedging Agreements, the obligations of the
Guarantors hereunder and the other Loan Documents shall be limited to an
aggregate amount equal to the largest amount that would not render such
obligations subject to avoidance under Section 548 of the Bankruptcy Code or any
comparable provisions of any applicable state law.

         2.2      OBLIGATIONS UNCONDITIONAL.

         The obligations of the Guarantors under Section 2.1 are joint and
several, absolute and unconditional, irrespective of the value, genuineness,
validity, regularity or enforceability of any of the Loan Documents or Hedging
Agreements, or any other agreement or instrument referred to therein, or any
substitution, compromise, release, impairment or exchange of any other guarantee
of or security for any of the Guaranteed Obligations, and, to the fullest extent
permitted by applicable law, irrespective of any other circumstance whatsoever
which might otherwise constitute a legal or equitable discharge or defense of a
surety or guarantor, it being the intent of this Section 2.2 that the
obligations of the Guarantors hereunder shall be absolute and unconditional
under any and all circumstances. Each Guarantor agrees that it shall have no
right of subrogation, indemnity,

                                       4
<PAGE>

reimbursement or contribution against the Borrower or any other guarantor for
amounts paid under this Section 2 until such time as the Lenders (and any
Affiliates of the Lenders entering into Hedging Agreements) have been paid in
full, all Commitments under the Loan Agreement have been terminated and no
Person or Governmental Authority shall have any right to request any return or
reimbursement of funds from the Lenders in connection with monies received under
the Loan Documents or Hedging Agreements. Without limiting the generality of the
foregoing, it is agreed that, to the fullest extent permitted by law, the
occurrence of any one or more of the following shall not alter or impair the
liability of the Guarantors hereunder which shall remain absolute and
unconditional as described above:

                  (a) at any time or from time to time, without notice to the
         Guarantor, the time for any performance of or compliance with any of
         the Guaranteed Obligations shall be extended, or such performance or
         compliance shall be waived;

                  (b) any of the acts mentioned in any of the provisions of any
         of the Loan Documents or Hedging Agreements or any other agreement or
         instrument referred to in the Loan Documents or Hedging Agreements
         shall be done or omitted;

                  (c) the maturity of any of the Guaranteed Obligations shall be
         accelerated, or any of the Guaranteed Obligations shall be modified,
         supplemented or amended in any respect, or any right under any of the
         Loan Documents or Hedging Agreements or any other agreement or
         instrument referred to in the Loan Documents or Hedging Agreements
         shall be waived, or any other guarantee of any of the Guaranteed
         Obligations or any security therefor shall be released, impaired or
         exchanged in whole or in part or otherwise dealt with;

                  (d) any Encumbrance granted to, or in favor of, the Agent or
         any Lender or Lenders as security for any of the Guaranteed Obligations
         shall fail to attach or be perfected; or

                  (e) any of the Guaranteed Obligations shall be determined to
         be void or voidable (including, without limitation, for the benefit of
         any creditor of the Guarantor) or shall be subordinated to the claims
         of any Person (including, without limitation, any creditor of a
         Guarantor).

With respect to its obligations hereunder, each Guarantor hereby expressly
waives diligence, presentment, demand of payment, protest, notice of acceptance
of this Guaranty and of extensions of credit which may constitute Guaranteed
Obligations, notice of amendments, waivers or supplements to the Loan Documents
(except for any such notice required by the Loan Agreement) or Hedging
Agreements or the compromise, release or exchange of collateral or security and
all other notices whatsoever, and any requirement that the Agent or any Lender
exhaust any right, power or remedy or proceed against any Person under any of
the Loan Documents or Hedging Agreements or any other agreement or instrument
referred to in the Loan Documents or against any other Person under any other
guarantee of, or security for, any of the Guaranteed Obligations.

         2.3      REINSTATEMENT.

         Neither the Guarantors' obligations hereunder nor any remedy for the
enforcement thereof shall be impaired, modified, changed or released in any
manner whatsoever by an impairment, modification, change, release or limitation
of the liability of the Borrower, by reason of the Borrower's bankruptcy or
insolvency or by reason of the invalidity or unenforceability of all or any
portion of the Guaranteed Obligations. The obligations of the Guarantors under
this Guaranty shall be automatically reinstated if and to the extent that for
any reason any payment by or on behalf of any Person in respect of the
Guaranteed Obligations is rescinded or must be otherwise restored by any holder
of any of the Guaranteed Obligations, whether as a result of any proceedings in
bankruptcy or reorganization or otherwise, and the Guarantor agrees that it will
indemnify the Agent and each Lender on demand for all costs and expenses
(including, without limitation, reasonable fees and expenses of counsel)
incurred by the Agent or such Lender in connection with such rescission or
restoration, including any such costs and expenses incurred in defending against
any claim alleging that such payment constituted a preference, fraudulent
transfer or similar payment under any bankruptcy, insolvency or similar law.

         2.4      CERTAIN ADDITIONAL WAIVERS.

         Each of the Guarantors agrees that this Guaranty may be enforced by the
Agent and the Lenders without the necessity of resorting to or exhausting any
other security or collateral and without the necessity at any time of having
recourse to the Borrower under the Loan Agreement, any Hedging Agreement or any
collateral securing the Guaranteed Obligations or otherwise, and the Guarantor
agrees not to assert any right to require the Agent and the Lenders to proceed
against the Borrower or any other Person (including any co-guarantor) or to
require the Agent and the Lenders to pursue any other remedy or enforce any
other right. Each Guarantor further acknowledges and agrees that nothing
contained in this Guaranty shall prevent the Agent or the Lenders from suing the
Borrower in respect of its obligations under the Loan Agreement, any Hedging
Agreement and the other Loan Documents or foreclosing on any security interest
or lien on any collateral securing the Guaranteed Obligations or from exercising
any other rights available to the Agent and the Lenders under the Loan Documents
or Hedging Agreements if neither the Borrower nor the Guarantors timely perform
their obligations, and the exercise of any of such rights and completion of any
such foreclosure proceedings shall not constitute a discharge of any of the
Guarantors' obligations hereunder unless as a result thereof the Guaranteed
Obligations shall have been paid in full and all of the Commitments shall have
terminated or expired, it being the purpose and intent that the Guarantor's
obligations hereunder be absolute, irrevocable, independent and unconditional
under all circumstances.

         2.5      REMEDIES.

         Each Guarantor agrees that, to the fullest extent permitted by law, as
between the Guarantors, on the one hand, and the Agent and the Lenders, on the
other hand, the Guaranteed Obligations may be declared to be forthwith due and
payable as provided in Section 8.2 of the Loan Agreement (and shall be deemed to
have become automatically due and payable in the circumstances provided in said
Section 8.2 of the Loan Agreement) for purposes of Section 2.1 notwithstanding
any stay, injunction or other prohibition preventing such declaration (or

                                       6
<PAGE>

preventing such Guaranteed Obligations from becoming automatically due and
payable) as against any other Person and that, in the event of such declaration
(or such Guaranteed Obligations being deemed to have become automatically due
and payable), such Guaranteed Obligations (whether or not due and payable by any
other Person) shall forthwith become due and payable by the Guarantor for
purposes of Section 2.1.

         2.6      CERTAIN REPRESENTATIONS AND WARRANTIES.

         The Guarantors agree that the Agent and the Lenders will have no
obligation to investigate the financial condition or affairs of the Borrower for
the benefit of the Guarantors nor to advise the Guarantors of any fact
respecting, or any change in, the financial condition or affairs of the Borrower
which might come to the knowledge of the Agent or any Lender at any time,
whether or not the Agent or any Lender knows or believes or has reason to know
or believe that any such fact or change is unknown to the Guarantors or might
(or does) materially increase the risk of the Guarantors as guarantors or might
(or would) affect the willingness of the Guarantors to continue as guarantors
with respect to the Guaranteed Obligations.

         2.7      ADDITIONAL LIABILITY OF GUARANTORS.

         If any Guarantor is or becomes liable for any indebtedness owing by
such Guarantor to the Agent or any Lender by endorsement or otherwise other than
under this Guaranty, such liability shall not be in any manner impaired or
reduced hereby but shall have all and the same force and effect it would have
had if this Guaranty had not existed and the Guarantors' liability hereunder
shall not be in any manner impaired or reduced thereby.

         2.8      GUARANTEE OF PAYMENT; CONTINUING GUARANTEE.

         The guaranty in this Section 2 is a guaranty of payment and not of
collection, is a continuing guaranty, and shall apply to all Guaranteed
Obligations whenever owing.

         2.9      RIGHTS OF CONTRIBUTION.

         The Guarantors hereby agree as among themselves that, if any Guarantor
shall make an Excess Payment (as defined below), such Guarantor shall have a
right of contribution from each other Guarantor in an amount equal to such other
Guarantor's Contribution Share (as defined below) of such Excess Payment. The
payment obligations of any Guarantor under this Section 2.9 shall be subordinate
and subject in right of payment to the prior payment in full to the Agent and
the Lenders of the Guaranteed Obligations, and none of the Guarantors shall
exercise any right or remedy under this Section 2.9 against any other Guarantor
until payment and satisfaction in full of all of such Guaranteed Obligations.
For purposes of this Section 2.9, (a) "Excess Payment" shall mean the amount
paid by any Guarantor in excess of its Pro Rata Share of any Guaranteed
Obligations; (b) "Pro Rata Share" shall mean, for any Guarantor in respect of
any payment of Guaranteed Obligations, the ratio (expressed as a percentage) as
of the date of such payment of Guaranteed Obligations of (i) the amount by which
the aggregate present fair salable value of all of its assets and facilities
exceeds the amount of all debts and liabilities of such Guarantor (including
contingent, subordinated, unmatured, and unliquidated

                                       7
<PAGE>

liabilities, but excluding the obligations of such Guarantor hereunder) to (ii)
the amount by which the aggregate present fair salable value of all assets and
other facilities of the Borrower and all of the Guarantors exceeds the amount of
all of the debts and liabilities (including contingent, subordinated, unmatured,
and unliquidated liabilities, but excluding the obligations of the Borrower and
the Guarantors hereunder) of the Borrower and all of the Guarantors; provided,
however, that, for purposes of calculating the Pro Rata Shares of the Guarantors
in respect of any payment of Guaranteed Obligations, any Guarantor that became a
Guarantor subsequent to the date of any such payment shall be deemed to have
been a Guarantor on the date of such payment and the financial information for
such Guarantor as of the date such Guarantor became a Guarantor shall be
utilized for such Guarantor in connection with such payment; and (c)
"Contribution Share" shall mean, for any Guarantor in respect of any Excess
Payment made by any other Guarantor, the ratio (expressed as a percentage) as of
the date of such Excess Payment of (i) the amount by which the aggregate present
fair salable value of all of its assets and facilities exceeds the amount of all
debts and liabilities of such Guarantor (including contingent, subordinated,
unmatured, and unliquidated liabilities, but excluding the obligations of such
Guarantor hereunder) to (ii) the amount by which the aggregate present fair
salable value of all assets and other facilities of the Borrower and all of the
Guarantors other than the maker of such Excess Payment exceeds the amount of all
of the debts and liabilities (including contingent, subordinated, unmatured, and
unliquidated liabilities, but excluding the obligations of the Borrower and the
Guarantors hereunder) of the Borrower and all of the Guarantors other than the
maker of such Excess Payment; provided, however, that, for purposes of
calculating the Contribution Shares of the Guarantors in respect of any Excess
Payment, any Guarantor that became a Guarantor subsequent to the date of any
such Excess Payment shall be deemed to have been a Guarantor on the date of such
Excess Payment and the financial information for such Guarantor as of the date
such Guarantor became a Guarantor shall be utilized for such Guarantor in
connection with such Excess Payment. This Section 2.9 shall not be deemed to
affect any right of subrogation, indemnity, reimbursement or contribution that
any Guarantor may have under applicable law against the Borrower in respect of
any payment of Guaranteed Obligations.

                                    SECTION 3
                    REPRESENTATIONS, WARRANTIES AND COVENANTS

         The representations and warranties contained in Section IV of the Loan
Agreement (the "Incorporated Representations") and the affirmative and negative
covenants contained in Sections V and VI of the Loan Agreement (the
"Incorporated Covenants") are incorporated herein by reference, mutatis
mutandis, for the benefit of the Agent and the Lenders to the same extent and
with the same effect as if set forth fully herein (such incorporation to include
all other relevant provisions of the Loan Agreement related thereto, including
without limitation the defined terms contained in Section 1 thereof which are
used in the Incorporated Representations and the Incorporated Covenants). Each
Guarantor affirms and represents and warrants to the Agent and the Lenders that
the Incorporated Representations are true and correct in all material respects
as of the date hereof and covenants and agrees that the Incorporated Covenants
shall be as binding on the Guarantors as if set forth fully herein.

                                    SECTION 4
                                EVENTS OF DEFAULT

         4.1      EVENTS OF DEFAULT.

         The occurrence of an event which would constitute an Event of Default
under the Loan Agreement shall be an Event of Default hereunder (each an "Event
of Default").

         4.2      REMEDIES.

         Upon the occurrence of an Event of Default, and at any time thereafter
unless and until such Event of Default has been waived by the requisite Lenders
(pursuant to the voting requirements of Section 10.15 of the Loan Agreement) or
cured to the satisfaction of the requisite Lenders (pursuant to the voting
procedures in Section 10.15 of the Loan Agreement), the Agent may, or shall,
upon the request and direction of the Required Lenders, by written notice to the
Credit Parties, enforce any and all rights and interests created and existing
under the Loan Documents including, without limitation, all rights and remedies
existing under the Collateral Documents (including, without limitation, this
Guaranty), all rights and remedies against the Guarantor and all rights of
set-off.

                                    SECTION 5
                                  MISCELLANEOUS

         5.1      CUMULATIVE RIGHTS.

         All rights of the Agent and the Lenders hereunder or otherwise arising
under any documents executed in connection with or as security for the
Guaranteed Obligations are separate and cumulative and may be pursued
separately, successively or concurrently, or not pursued, without affecting or
limiting any other right of the Agent or any Lender and without affecting or
impairing the liability of the Guarantors.

         5.2      USURY.

         Notwithstanding any other provisions herein contained, no provision of
this Guaranty shall require or permit the collection from the Guarantors of
interest in excess of the maximum rate or amount that the Guarantors may be
required or permitted to pay pursuant to any applicable law. In the event any
such interest is collected, it shall be applied in reduction of the Guarantors'
obligations hereunder, and the remainder of such excess collected shall be
returned to the Guarantors once such obligations have been fully satisfied.

         5.3      RIGHT OF SET-OFF.

         After the occurrence of an Event of Default, any Lender may set-off any
matured obligation owed by the Guarantors under this Guaranty (to the extent
beneficially owned or held

                                       9
<PAGE>

by such Lender) against any obligation (whether or not matured) owed by such
Lender to any Guarantor, regardless of the place of payment.

         5.4      TERM OF GUARANTEE.

         This Guaranty shall continue in full force and effect until the
Guaranteed Obligations are fully and indefeasibly paid, performed and discharged
and all Commitments have expired or been terminated. This Guaranty covers the
Guaranteed Obligations whether presently outstanding or arising subsequent to
the date hereof including all amounts advanced by the Agent or any Lender in
stages or installments.

         5.5      THE AGENT.

         In acting under or by virtue of this Guaranty, the Agent shall be
entitled to all the rights, authority, privileges and immunities provided in the
Loan Agreement, all of which provisions are incorporated by reference herein
with the same force and effect as if set forth herein.

         5.6      SUCCESSORS AND ASSIGNS.

         This Guaranty shall be binding on and enforceable against the Guarantor
and its successors and assigns; provided that, the Guarantor may not assign or
transfer any of its obligations hereunder without prior written consent of the
Lenders. This Guaranty is intended for and shall inure to the benefit of the
Agent and each Lender and each and every person who shall from time to time be
or become the owner or holder of any of the Guaranteed Obligations, and each and
every reference herein to the "Agent" or the "Lender" shall include and refer to
each and every successor or assignee of the Agent or any Lender at any time
holding or owning any part of or interest in any part of the Guaranteed
Obligations. This Guaranty shall be transferable and negotiable with the same
force and effect, and to the same extent, that the Guaranteed Obligations are
transferable and negotiable, it being understood and stipulated that upon
assignment or transfer by the Agent or any Lender of any of the Guaranteed
Obligations the legal holder or owner of the Guaranteed Obligations (or a part
thereof or interest therein thus transferred or assigned by the Agent or any
Lender) shall (except as otherwise stipulated by the Agent or any such Lender in
its assignment) have and may exercise all of the rights granted to the Agent or
such Lender under this Guaranty to the extent of that part of or interest in the
Guaranteed Obligations thus assigned or transferred to said person. The
Guarantor expressly waives notice of transfer or assignment by the Lenders of
the Guaranteed Obligations, or any part thereof, or of the rights of the Agent
or any Lender hereunder. Failure to give notice will not affect the liabilities
of the Guarantor hereunder.

         5.7      APPLICATION OF PAYMENTS.

         Each of the Agent and the Lenders may apply any payments received by it
from any source against that portion of the Guaranteed Obligations (principal,
interest, court costs, attorneys' fees or other) as set forth in Section 9.9 of
the Loan Agreement.

         thereto, excluding, in the case of each Lender and the Agent, taxes
         imposed on or measured by its income or capital, and franchise taxes
         imposed on it, by the jurisdiction under the laws of which such Lender
         (or its Applicable Lending Office) or the Agent (as the case may be) is
         organized or maintains a lending office or any political subdivision
         thereof (all such non-excluded taxes, duties, levies, imposts,
         deductions, charges, withholdings, and liabilities being hereinafter
         referred to as "Taxes"). If a Guarantor shall be required by law to
         deduct any Taxes from or in respect of any sum payable under this
         Guaranty or any other Loan Document to any Lender or the Agent (except
         as permitted under subsection (e) below), (i) the sum payable shall be
         increased as necessary so that after making all required deductions
         (including deductions applicable to additional sums payable under this
         Section 5.10) such Lender or the Agent receives an amount equal to the
         sum it would have received had no such deductions been made, (ii) the
         Guarantors shall make such deductions, (iii) the Guarantors shall pay
         the full amount deducted to the relevant taxation authority or other
         authority in accordance with applicable law, and (iv) the Guarantors
         shall furnish to the Agent, at its address referred to in Section 5.9,
         the original or a certified copy of a receipt evidencing payment
         thereof.

                  (b) Other Taxes. In addition, each Guarantor agrees to pay any
         and all present or future stamp or documentary taxes, property taxes
         and any other excise or similar taxes or charges or levies which arise
         from any payment made under this Guaranty or any other Loan Document or
         from the execution or delivery of, or otherwise with respect to, this
         Guaranty or any other Loan Document (hereinafter referred to as "Other
         Taxes").

                  (c) Indemnity. Each Guarantor agrees to indemnify each Lender
         and the Agent for the full amount of Taxes and Other Taxes (including,
         without limitation, any Taxes or Other Taxes imposed or asserted by any
         jurisdiction on amounts payable under this Section 5.10) paid by such
         Lender or the Agent (as the case may be) and any liability (including
         penalties, interest, and expenses) arising therefrom or with respect
         thereto.

                  (d) Evidence of Payment. Within thirty (30) days after the
         date of any payment of Taxes, the Guarantor shall furnish to the Agent
         the original or a certified copy of a receipt evidencing such payment.

                  (e) Survival. Without prejudice to the survival of any other
         agreement of the Borrower hereunder, the agreements and obligations of
         the Borrower contained in this Section 5.10 shall survive the repayment
         of the Loans and other obligations under the Loan Documents and the
         termination of the Commitments hereunder.

                  (f) Lending Offices. If the Guarantors are required to pay
         additional amounts to or for the account of any Lender pursuant to this
         Section 5.10, such Lender has agreed in Section 9.13.6 of the Loan
         Agreement to use reasonable efforts to change the jurisdiction of its
         Applicable Lending Office so as to eliminate or reduce any such
         additional payment which may thereafter accrue if such change, in the
         judgment of such Lender, is not otherwise disadvantageous to such
         Lender

         5.11     SEVERABILITY.

         If any provision of this Guaranty is determined to be illegal, invalid
or unenforceable, such provision shall be fully severable and the remaining
provisions shall remain in full force and effect and shall be construed without
giving effect to the illegal, invalid or unenforceable provisions.

         5.12     GOVERNING LAW; SUBMISSION TO JURISDICTION; VENUE.

          THIS GUARANTY AND THE RIGHTS AND OBLIGATIONS OF THE PARTIES HEREUNDER
SHALL BE GOVERNED BY AND CONSTRUED AND INTERPRETED IN ACCORDANCE WITH THE LAWS
OF THE STATE OF GEORGIA. The provisions of each of the Loan Agreement relating
to submission to jurisdiction and venue are hereby incorporated by reference
herein, mutatis mutandis.

         5.13     WAIVER OF JURY TRIAL.

         TO THE EXTENT PERMITTED BY APPLICABLE LAW, EACH OF THE PARTIES TO THIS
GUARANTY HEREBY IRREVOCABLY WAIVES ALL RIGHT TO TRIAL BY JURY IN ANY ACTION,
PROCEEDING OR COUNTERCLAIM ARISING OUT OF OR RELATING TO THIS GUARANTY OR THE
TRANSACTIONS CONTEMPLATED HEREBY.

         5.14     HEADINGS.

         The headings of the sections and subsections hereof are provided for
convenience only and shall not in any way affect the meaning or construction of
any provision of this Guaranty.

         5.15     COUNTERPARTS.

         This Guaranty may be executed in any number of counterparts, each of
which where so executed and delivered shall be an original, but all of which
shall constitute one and the same instrument. It shall not be necessary in
making proof of this Guaranty to produce or account for more than one such
counterpart.

         5.16     RIGHTS OF THE REQUIRED LENDERS.

         All rights of the Agent hereunder, if not exercised by the Agent, may
be exercised by the Required Lenders.

         5.17     JOINT AND SEVERAL OBLIGATIONS OF GUARANTORS.

                  (a) Each of the Guarantors is accepting joint and several
         liability hereunder in consideration of the financial accommodation to
         be provided by the holders of the Guaranteed Obligations, for the
         mutual benefit, directly and indirectly, of each of the Guarantors and
         in consideration of the undertakings of each of the Guarantors to
         accept joint and several liability for the obligations of each of them.

                  (b) Each of the Guarantors jointly and severally hereby
         irrevocably and unconditionally accepts, not merely as a surety but
         also as a co-debtor, joint and several liability with the other
         Guarantors with respect to the payment and performance of all of the
         Guaranteed Obligations arising under this Guaranty, the Loan Agreement,
         the other Loan Documents and any other documents relating to the
         Guaranteed Obligations, it being the intention of the parties hereto
         that all the Guaranteed Obligations shall be the joint and several
         obligations of each of the Guarantors without preferences or
         distinction among them.

                  (c) Notwithstanding any provision to the contrary contained
         herein, in the Loan Agreement, in any other of the Loan Documents or in
         any other documents relating to the Guaranteed Obligations, the
         obligations of each Guarantor under the Loan Agreement and the other
         Loan Documents shall be limited to an aggregate amount equal to the
         largest amount that would not render such obligations subject to
         avoidance under Section 548 of the Bankruptcy Code or any comparable
         provisions of any applicable state law.

         instrument, option, right or distribution in trust for the benefit of
         the Agent, shall segregate it from such Grantor's other property and

         together with any necessary endorsement and/or appropriate stock power
         duly executed in blank, substantially in the form provided in Exhibit

         security for the Secured Obligations.

                  (c) Financing Statements. Each Grantor shall execute and
         deliver to the Agent such UCC or other applicable financing statements
         as may be reasonably requested by the Agent in order to perfect and
         protect the security interest created hereby in the Collateral of such
         Grantor.

         5. Representations and Warranties. Each Grantor hereby represents and
warrants to the Agent, for the benefit of the holders of the Secured
Obligations, that so long as any of the Secured Obligations remains outstanding
and until all of the commitments relating thereto have been terminated:

                  (a) Authorization of Pledged Shares. The Pledged Shares are
         duly authorized and validly issued, are fully paid and nonassessable
         and are not subject to the preemptive rights of any Person.

                  (b) Title. Each Grantor has good and indefeasible title to the
         Collateral of such Grantor and will at all times be the legal and
         beneficial owner of such Collateral free and clear of any Encumbrance,
         other than Permitted Encumbrances. There exists no "adverse claim"
         within the meaning of Section 8-102 of the UCC with respect to the
         Pledged Shares of such Grantor.

                  (c) Exercising of Rights. The exercise by the Agent of its
         rights and remedies hereunder will not violate any law or governmental
         regulation or any material contractual restriction binding on or
         affecting a Grantor or any of its property.

                  (d) Grantor's Authority. No authorization, approval or action
         by, and no notice or filing with any Governmental Authority or with the
         issuer of any Pledged Stock is required either (i) for the pledge made
         by a Grantor or for the granting of the security interest by a Grantor
         pursuant to this Security Agreement (except as have been already
         obtained) or (ii) for the exercise by the Agent or the holders of the
         Secured Obligations of their rights and remedies hereunder (except as
         may be required by laws affecting the offering and sale of securities).

                  (e) Security Interest/Priority. This Security Agreement
         creates a valid security interest in favor of the Agent for the benefit
         of the holders of the Secured

                                       5
<PAGE>

         Obligations, in the Collateral. The taking of possession by the Agent
         of the certificates representing the Pledged Shares and all other
         certificates and instruments constituting Collateral will perfect and
         establish the first priority of the Agent's security interest in the
         Pledged Shares and, when properly perfected by filing or registration,
         in all other Collateral represented by such Pledged Shares and
         instruments securing the Secured Obligations. Except as set forth in
         this Section 5(e), no action is necessary to perfect or otherwise
         protect such security interest.

                  (f) Partnership and Membership Interests. Except as previously
         disclosed to the Agent, none of the Pledged Shares consisting of
         partnership or limited liability company interests (i) is dealt in or
         traded on a securities exchange or in a securities market, (ii) by its
         terms expressly provides that it is a security governed by Article 8 of
         the UCC, (iii) is an investment company security, (iv) is held in a
         securities account or (v) constitutes a Security or a Financial Asset.

                  (g) No Other Interests. No Grantor owns any Capital Stock in
         any Subsidiary other than as set forth on Schedule 2(a) attached
         hereto.

         6. Covenants. Each Grantor hereby covenants, that so long as any of the
Secured Obligations remains outstanding and until all of the commitments
relating thereto have been terminated, such Grantor shall:

                  (a) Books and Records. Mark its books and records (and shall
         cause the issuer of the Pledged Shares of such Grantor to mark its
         books and records) to reflect the security interest granted to the
         Agent, for the benefit of the holders of the Secured Obligations,
         pursuant to this Security Agreement.

                  (b) Defense of Title. Warrant and defend title to and
         ownership of the Collateral of such Grantor at its own expense against
         the claims and demands of all other parties claiming an interest
         therein, keep the Collateral free from all Encumbrances, except for
         Permitted Encumbrances, and not sell, exchange, transfer, assign, lease
         or otherwise dispose of Collateral of such Grantor or any interest
         therein, except as permitted under the Credit Agreements and the other
         Credit Documents.

                  (c) Further Assurances. Promptly execute and deliver at its
         expense all further instruments and documents and take all further
         action that may be necessary and desirable or that the Agent may
         reasonably request in order to (i) perfect and protect the security
         interest created hereby in the Collateral of such Grantor (including,
         without limitation, any and all action necessary to satisfy the Agent
         that the Agent has obtained a first priority perfected security
         interest in all Collateral); (ii) enable the Agent to exercise and
         enforce its rights and remedies hereunder in respect of the Collateral
         of such Grantor; and (iii) otherwise effect the purposes of this
         Security Agreement, including, without limitation and if requested by
         the Agent, delivering to the Agent irrevocable proxies in respect of
         the Collateral of such Grantor.

         other information now or hereafter required to be filed by such Grantor

         the Collateral of such Grantor.

                  (f) Issuance or Acquisition of Capital Stock. Not, without
         providing 30 days prior written notice to the Agent and without
         executing and delivering, or causing to be executed and delivered, to
         the Agent such agreements, documents and instruments as the Agent may
         require, issue or acquire any Capital Stock consisting of an interest
         in a partnership or a limited liability company that (i) is dealt in or
         traded on a securities exchange or in a securities market, (ii) by its
         terms expressly provides that it is a security governed by Article 8 of
         the UCC, (iii) is an investment company security, (iv) is held in a
         securities account or (v) constitutes a Security or a Financial Asset.

         7. Advances by Holders of the Secured Obligations. On failure of any
Grantor to perform any of the covenants and agreements contained herein, the
Agent may, at its sole option and in its sole discretion, perform the same and
in so doing may expend such sums as the Agent may reasonably deem advisable in
the performance thereof, including, without limitation, the payment of any
insurance premiums, the payment of any taxes, a payment to obtain a release of a
Encumbrance or potential Encumbrance, expenditures made in defending against any
adverse claim and all other expenditures which the Agent or the holders of the
Secured Obligations may make for the protection of the security hereof or which
may be compelled to make by operation of law. All such sums and amounts so
expended shall be repayable by the Grantors on a joint and several basis
promptly upon timely notice thereof and demand therefor, shall constitute
additional Secured Obligations and shall bear interest from the date said
amounts are expended at the Default Rate. No such performance of any covenant or
agreement by the Agent or the holders of the Secured Obligations on behalf of
any Grantor, and no such advance or expenditure therefor, shall relieve the
Grantors of any default under the terms of this Security Agreement, the Credit
Agreements, the other Credit Documents or any other documents relating to the
Secured Obligations. The holders of the Secured Obligations may make any payment
hereby authorized in accordance with any bill, statement or estimate procured
from the appropriate public office or holder of the claim to be discharged
without inquiry into the accuracy of such bill, statement or estimate or into
the validity of any tax assessment, sale, forfeiture, tax lien, title or claim
except to the extent such payment is being contested in good faith by a Grantor
in appropriate proceedings and against which adequate reserves are being
maintained in accordance with GAAP.

         8. Events of Default. The occurrence of an event which would constitute
an Event of Default under and as defined in the 364-Day Facility or the
Multi-Year Facility shall be an Event of Default hereunder (an "Event of
Default").

         9.       Remedies.

                  (a) General Remedies. Upon the occurrence of an Event of
         Default and during the continuation thereof, the Agent and the holders
         of the Secured Obligations shall have, in addition to the rights and
         remedies provided herein, in the in the Credit Agreements, in the other
         Credit Documents, in any other documents relating to the Secured
         Obligations, or by law (including, without limitation, levy of
         attachment and garnishment), the rights and remedies of a secured party
         under the UCC of the jurisdiction applicable to the affected
         Collateral.

                  (b) Sale of Collateral. Upon the occurrence of an Event of
         Default and during the continuation thereof, without limiting the
         generality of this Section 9 and without notice, the Agent may, in its
         sole discretion, sell or otherwise dispose of or realize upon the
         Collateral, or any part thereof, in one or more parcels, at public or
         private sale, at any exchange or broker's board or elsewhere, at such
         price or prices and on such other terms as the Agent may deem
         commercially reasonable, for cash, credit or for future delivery or
         otherwise in accordance with applicable law. To the extent permitted by
         law, any holder of the Secured Obligations may in such event, bid for
         the purchase of such securities. Each Grantor agrees that, to the
         extent notice of sale shall be required by law and has not been waived
         by such Grantor, any requirement of reasonable notice shall be met if
         notice, specifying the place of any public sale or the time after which
         any private sale is to be made, is personally served on or mailed,
         postage prepaid, to such Grantor, in accordance with the notice
         provisions of Section 10.1 of each of the Credit Agreements at least
         ten days before the time of such sale. The Agent shall not be obligated
         to make any sale of Collateral of such Grantor regardless of notice of
         sale having been given. The Agent may adjourn any public or private
         sale from time to time by announcement at the time and place fixed
         therefor, and such sale may, without further notice, be made at the
         time and place to which it was so adjourned.

                  (c) Private Sale. Upon the occurrence of an Event of Default
         and during the continuation thereof, the Grantors recognize that the
         Agent may deem it impracticable to effect a public sale of all or any
         part of the Pledged Shares or any of the securities constituting
         Collateral and that the Agent may, therefore, determine to make one or
         more private sales of any such Collateral to a restricted group of
         purchasers who will be obligated to agree, among other things, to
         acquire such Collateral for their own account, for investment and not
         with a view to the distribution or resale thereof. Each Grantor
         acknowledges that any such private sale may be at prices and on terms
         less favorable to the seller than the prices and other terms which
         might have been obtained at a public sale and, notwithstanding the
         foregoing, agrees that such private sale shall be deemed to have been
         made in a commercially reasonable manner and that the Agent shall have
         no obligation to delay sale of any such Collateral for the period of
         time necessary to permit the issuer of such Collateral to register such
         Collateral for public sale under the Securities Act. Each Grantor
         further acknowledges and agrees that any offer to sell such Collateral
         which has been (i) publicly advertised on a bona fide basis in a
         newspaper or other publication of general circulation in the financial
         community of New York, New York (to the extent that such offer may be
         advertised without prior registration under the Securities

                                       8
<PAGE>

         Act), or (ii) made privately in the manner described above shall be
         deemed to involve a "public sale" under the UCC, notwithstanding that
         such sale may not constitute a "public offering" under the Securities
         Act, and the Agent may, in such event, bid for the purchase of such
         Collateral.

                  (d) Retention of Collateral. To the extent permitted under
         applicable law, in addition to the rights and remedies hereunder, upon
         the occurrence of an Event of Default, the Agent may, after providing
         the notices required by Sections 9-620 and 9-621 of the UCC or
         otherwise complying with the requirements of applicable law of the
         relevant jurisdiction, accept or retain all or any portion of the
         Collateral in satisfaction of the Secured Obligations. Unless and until
         the Agent shall have provided such notices, however, the Agent shall
         not be deemed to have accepted or retained any Collateral in
         satisfaction of any Secured Obligations for any reason.

                  (e) Deficiency. In the event that the proceeds of any sale,
         collection or realization are insufficient to pay all amounts to which
         the Agent or the holders of the Secured Obligations are legally
         entitled, the Grantors shall be jointly and severally liable for the
         deficiency, together with interest thereon at the Default Rate,
         together with the costs of collection and reasonable attorneys' fees
         and expenses. Any surplus remaining after the full payment and
         satisfaction of the Secured Obligations shall be returned to the
         Grantors or to whomsoever a court of competent jurisdiction shall
         determine to be entitled thereto.

                  (f) Authorization to File Financing Statements. Each Grantor
         authorized the Agent to prepare and file such financing statements
         (including renewal statements), amendments and supplements or such
         other instruments as the Agent may from time to time reasonably deem
         necessary in order to perfect and maintain the security interests
         granted hereunder in accordance with the UCC.

         10.      Rights of the Agent.

                  (a) Power of Attorney. In addition to other powers of attorney
         contained herein, each Grantor hereby designates and appoints the
         Agent, on behalf of the holders of the Secured Obligations, and each of
         its designees or agents, as attorney-in-fact of such Grantor,
         irrevocably and with power of substitution, with authority to take any
         or all of the following actions upon the occurrence and during the
         continuation of an Event of Default:

                  adjust, and give discharges and releases concerning the
                  Collateral, all as the Agent may reasonably deem appropriate;

                           (ii) to commence and prosecute any actions at any
                  court for the purposes of collecting any of the Collateral and
                  enforcing any other right in respect thereof;

                                       9
<PAGE>

                           (iii) to defend, settle or compromise any action
                  brought and, in connection therewith, give such discharge or
                  release as the Agent may reasonably deem appropriate;

                           (iv) to pay or discharge taxes, liens, security
                  interests or other encumbrances levied or placed on or
                  threatened against the Collateral;

                           (v) to direct any parties liable for any payment in
                  connection with any of the Collateral to make payment of any
                  and all monies due and to become due thereunder directly to
                  the Agent or as the Agent shall direct;

                           (vi) to receive payment of and receipt for any and
                  all monies, claims, and other amounts due and to become due at
                  any time in respect of or arising out of any Collateral;

                           (vii) to sign and endorse any drafts, assignments,
                  proxies, stock powers, verifications, notices and other
                  documents relating to the Collateral;

                           (viii) to execute and deliver all assignments,
                  conveyances, statements, financing statements, renewal
                  financing statements, security and pledge agreements,
                  affidavits, notices and other agreements, instruments and
                  documents that the Agent may reasonably deem appropriate in
                  order to perfect and maintain the security interests and liens
                  granted in this Security Agreement and in order to fully
                  consummate all of the transactions contemplated therein;

                           (ix) to exchange any of the Collateral or other
                  property upon any merger, consolidation, reorganization,
                  recapitalization or other readjustment of the issuer thereof
                  and, in connection therewith, deposit any of the Collateral
                  with any committee, depository, transfer agent, registrar or
                  other designated agency upon such terms as the Agent may
                  reasonably deem appropriate;

                           (x) to vote for a shareholder resolution, or to sign
                  an instrument in writing, sanctioning the transfer of any or
                  all of the Collateral into the name of the Agent or one or
                  more of the holders of the Secured Obligations or into the
                  name of any transferee to whom the Collateral or any part
                  thereof may be sold pursuant to Section 9 hereof; and

                           (xi) to do and perform all such other acts and things
                  as the Agent may reasonably deem appropriate or convenient in
                  connection with the Collateral.

                  This power of attorney is a power coupled with an interest and
         shall be irrevocable for so long as any of the Secured Obligations
         shall remain outstanding and until all of the commitments relating
         thereto shall have been terminated. The Agent shall be under no duty to
         exercise or withhold the exercise of any of the rights, powers,
         privileges and options expressly or implicitly granted to the Agent in
         this Security Agreement, and shall not be liable for any failure to do
         so or any delay in doing so. The

                                       10
<PAGE>

         Agent shall not be liable for any act or omission or for any error of
         judgment or any mistake of fact or law in its individual capacity or
         its capacity as attorney-in-fact except acts or omissions resulting
         from its gross negligence or willful misconduct. This power of attorney
         is conferred on the Agent solely to protect, preserve and realize upon
         its security interest in the Collateral.

                  (b) Performance by the Agent of Obligations. If any Grantor
         fails to perform any agreement or obligation contained herein, the
         Agent itself may perform, or cause performance of, such agreement or
         obligation, and the expenses of the Agent incurred in connection
         therewith shall be payable by the Grantors on a joint and several basis
         pursuant to Section 26 hereof.

                  (c) Assignment by the Agent. The Agent may from time to time
         assign the Secured Obligations and any portion thereof and/or the
         Collateral and any portion thereof, and the assignee shall be entitled
         to all of the rights and remedies of the Agent under this Security
         Agreement in relation thereto.

                  (d) The Agent's Duty of Care. Other than the exercise of
         reasonable care to assure the safe custody of the Collateral while
         being held by the Agent hereunder, the Agent shall have no duty or
         liability to preserve rights pertaining thereto, it being understood
         and agreed that the Grantors shall be responsible for preservation of
         all rights in the Collateral, and the Agent shall be relieved of all
         responsibility for the Collateral upon surrendering it or tendering the
         surrender of it to the Grantors. The Agent shall be deemed to have
         exercised reasonable care in the custody and preservation of the
         Collateral in its possession if such Collateral is accorded treatment
         substantially equal to that which the Agent accords its own property,
         which shall be no less than the treatment employed by a reasonable and
         prudent agent in the industry, it being understood that the Agent shall
         not have responsibility for (i) ascertaining or taking action with
         respect to calls, conversions, exchanges, maturities, tenders or other
         matters relating to any Collateral, whether or not the Agent has or is
         deemed to have knowledge of such matters, or (ii) taking any necessary
         steps to preserve rights against any parties with respect to any of the
         Collateral.

                  (e)      Voting Rights in Respect of the Collateral.

                           (i) So long as no Event of Default shall have
                  occurred and be continuing, to the extent permitted by law,
                  each Grantor may exercise any and all voting and other
                  consensual rights pertaining to the Collateral of such Grantor
                  or any part thereof for any purpose not inconsistent with the
                  terms of this Security Agreement or either of the Credit
                  Agreements; and

                           (ii) Upon the occurrence and during the continuance
                  of an Event of Default, all rights of a Grantor to exercise
                  the voting and other consensual rights which it would
                  otherwise be entitled to exercise pursuant to paragraph (i) of
                  this subsection shall cease and all such rights shall
                  thereupon become vested in the

                                       11
<PAGE>

                  Agent which shall then have the sole right to exercise such
                  voting and other consensual rights.

                  (f)      Dividend Rights in Respect of the Collateral.

                           (i) So long as no Event of Default shall have
                  occurred and be continuing and subject to Section 4(b) hereof,
                  each Grantor may receive and retain any and all dividends
                  (other than stock dividends and other dividends constituting
                  Collateral addressed hereinabove) or interest paid in respect
                  of the Collateral to the extent they are allowed under each of
                  the Credit Agreements.

                           (ii) Upon the occurrence and during the continuance
                  of an Event of Default:

                                    (A) all rights of a Grantor to receive the
                           dividends and interest payments which it would
                           otherwise be authorized to receive and retain
                           pursuant to paragraph (i) of this subsection shall
                           cease and all such rights shall thereupon be vested
                           in the Agent, which shall then have the sole right to
                           receive and hold as Collateral such dividends and
                           interest payments; and

                                    (B) all dividends and interest payments
                           which are received by a Grantor contrary to the
                           provisions of paragraph (A) of this subsection shall
                           be received in trust for the benefit of the Agent,
                           shall be segregated from other property or funds of
                           such Grantor, and shall be forthwith paid over to the
                           Agent as Collateral in the exact form received, to be
                           held by the Agent as Collateral and as further
                           collateral security for the Secured Obligations.

                  (g) Release of Collateral. The Agent may release any of the
         Collateral from this Security Agreement or may substitute any of the
         Collateral for other Collateral without altering, varying or
         diminishing in any way the force, effect, lien, pledge or security
         interest of this Security Agreement as to any Collateral not expressly
         released or substituted, and this Security Agreement shall continue as
         a first priority lien on all Collateral not expressly released or
         substituted.

         11. Rights of the Required Lenders. All rights of the Agent hereunder,
if not exercised by the Agent, may be exercised by the Required Lenders.

         12. Application of Proceeds. Upon the occurrence and during the
continuation of an Event of Default, any payments in respect of the Secured
Obligations and any proceeds of the Collateral, when received by the Agent or
any of the holders of the Secured Obligations in cash or its equivalent, will be
applied in reduction of the Secured Obligations in the order set forth below:

                                       12
<PAGE>

                  (i) First, to the payment of the costs and expenses of the
         Agent (including without limitation reasonable attorneys' fees)
         incurred in connection with the execution of its duties as the Agent,
         in exercising or attempting to exercise any right or remedy hereunder
         or in taking possession of, protecting, preserving or disposing of any
         item of Collateral, and all protective advances made by the Agent with
         respect to the Collateral under or pursuant to the terms hereof;

                  (ii) Second, to the payment of any fees owed to the agent
         under either of the Credit Agreements;

                  (iii) Third, to the payment of all out-of-pocket expenses
         (including without limitation reasonable attorneys' fees) of each of
         the Secured Parties in connection with enforcing its rights under the
         Credit Documents or otherwise with respect to the Secured Obligations
         owing to such Secured Party;

                  (iv) Fourth, to the Lenders, ratably, in accordance with the
         respective amounts of the Secured Obligations constituting the then
         aggregate unpaid principal amount of the Loans, together with all
         accrued and unpaid interest thereon at such time; and

                  (v) Last, after payment in full of the Secured Obligations, to
         the payment of the surplus, if any, to whoever may be lawfully entitled
         to receive such surplus.

Each Grantor irrevocably waives the right to direct the application of such
payments and proceeds and acknowledges and agrees that the Agent shall have the
continuing and exclusive right to apply and reapply any and all such payments
and proceeds in the Agent's sole discretion, notwithstanding any entry to the
contrary upon any of its books and records. Payments by the Agent in respect of
(i) Secured Obligations related to the 364-Day Facility shall be made to the
agent under the 364-Day Facility for distribution to the 364-Day Lenders in
accordance with the 364-Day Facility, (ii) Secured Obligations related to the
Multi-Year Facility shall be made to the agent under the Multi-Year Facility for
distribution to the Multi-Year Lenders in accordance with the Multi-Year
Facility and (iii) Secured Obligations related to Hedging Agreements shall be
made to the party entitled thereto.

         13. Costs of Counsel. At all times hereafter, whether or not upon the
occurrence of an Event of Default, the Grantors agree to promptly pay upon
demand any and all reasonable costs and expenses (including, without limitation,
reasonable attorneys' fees and expenses) of the Agent and the holders of the
Secured Obligations (a) as required by the Credit Agreements and (b) as
necessary to protect the Collateral or to exercise any rights or remedies under
this Security Agreement or with respect to any of the Collateral. All of the
foregoing costs and expenses shall constitute Secured Obligations hereunder.

                                       13
<PAGE>

         14.      Continuing Agreement.

                  (a) This Security Agreement shall be a continuing agreement in
         every respect and shall remain in full force and effect so long as any
         of the Secured Obligations remains outstanding and until all of the
         commitments relating thereto have been terminated (other than any such
         obligations which by the terms thereof are stated to survive
         termination of the Credit Agreements and the other Credit Documents).
         Upon such payment and termination, this Security Agreement shall be
         automatically terminated and the Agent and the holders of the Secured
         Obligations shall, upon the request and at the expense of the Grantors,
         forthwith release all of its liens and security interests hereunder and
         shall execute and deliver all UCC termination statements and/or other
         documents reasonably requested by the Grantors evidencing such
         termination. Notwithstanding the foregoing, all releases and
         indemnities provided hereunder shall survive termination of this
         Security Agreement.

                  (b) This Security Agreement shall continue to be effective or
         be automatically reinstated, as the case may be, if at any time
         payment, in whole or in part, of any of the Secured Obligations is
         rescinded or must otherwise be restored or returned by the Agent or any

Documents or under any other document relating to the Secured Obligations.

         26.      Joint and Several Obligations of Grantors.

                  (a) Each of the Grantors is accepting joint and several
         liability hereunder in consideration of the financial accommodation to
         be provided by the holders of the Secured Obligations, for the mutual
         benefit, directly and indirectly, of each of the Grantors and in
         consideration of the undertakings of each of the Grantors to accept
         joint and several liability for the obligations of each of them.

                  (b) Each of the Grantors jointly and severally hereby
         irrevocably and unconditionally accepts, not merely as a surety but
         also as a co-debtor, joint and several liability with the other
         Grantors with respect to the payment and performance of all of the
         Secured Obligations arising under this Security Agreement, the Credit
         Agreements, the other Credit Documents and any other documents relating
         to the Secured Obligations, it being the intention of the parties
         hereto that all the Secured Obligations shall be the joint and several
         obligations of each of the Grantors without preferences or distinction
         among them.

                  (c) Notwithstanding any provision to the contrary contained
         herein, in either of the Credit Agreements, in any other of the Credit
         Documents or in any other documents relating to the Secured
         Obligations, the obligations of each Guarantor under either of the
         Credit Agreements and the other Credit Documents shall be limited to an
         aggregate amount equal to the largest amount that would not render such
         obligations subject to avoidance under Section 548 of the Bankruptcy
         Code or any comparable provisions of any applicable state law.

         27. Amendment and Restatement. Notwithstanding the amendment and
restatement of the Original Pledge on the date hereof, this Security Agreement
continues, and does not terminate or nullify any of the liens or security
interests heretofore created or granted by the Grantors in favor of the Agent or
in favor of Bank of America, N.A., in its capacity as the agent under the 1997
Loan Agreement, and all such existing liens and security interests shall remain
in full force and effect, without interruption in the attachment or perfection
of any such liens and security interests.

Agent to file financing statements (including renewal statements and in lieu
statements) and amendments thereof and supplements thereto with respect to the
Collateral in such form and in such filing offices as the Agent reasonably
determines appropriate to perfect the security interests of the Agent under this
Security Agreement. Any financing statement filed by the Agent may contain a
general description of the collateral covered thereby, as permitted by the UCC,
which states that the security interest attaches to all personal property of the
debtor.

         received by it as holder thereof for the account of Grantor.

                  (d) Binding Agreement. Each Collateral Note is the legal valid
         and binding obligation of, and is enforceable against the maker thereof
         (the "Obligor") according to its terms.

                  (e) No Other Assignment. No Collateral Note is subject to any
         assignment, lien or other encumbrance, except for the security interest
         provided for herein.

<PAGE>

                  (f) Payments Current. All payments required under the
         Collateral Notes are presently current.

                  (g) No Default. No default presently exists under any
         Collateral Note and no condition presently exists which, with the
         giving of notice, the passage of time, or both, will cause such a
         default.

                  (h) No Setoff. None of the debts evidenced by the Collateral
         Notes are subject to any defense or setoff except as may be provided by
         applicable law.

                  (i) Valid Assignment. This Assignment and the delivery of the
         Collateral Notes to the Agent for the benefit of the Lenders grants the
         Agent, for the benefit of the Lenders, a valid first priority security
         interest in the Collateral Notes.

                  (j) No Amendment or Waiver. Except as disclosed to the Agent
         in writing, no provision of the Collateral Notes have been amended or
         waived.

                  (k) Addresses of Obligors. The correct current addresses of
         Obligors under the Collateral Notes are correctly listed on Exhibit A
         hereto.

                  Without limiting the generality of the foregoing, it is hereby
         specifically understood and agreed that a Grantor may from time to time
         hereafter pledge and deliver additional promissory notes to the Agent
         as collateral security for the Secured Obligations. Upon such pledge
         and delivery to the Agent, such additional promissory notes shall be
         deemed to be part of the Collateral Notes of such Grantor, and shall be
         subject to the terms of this Assignment whether or not Exhibit A hereto
         is amended to refer to such additional promissory notes.

         5. Covenants. Each Grantor covenants with the Agent, for the benefit of
the holders of the Secured Obligations, that so long as any of the Secured
Obligations remains outstanding and until all of the commitments relating
thereto have been terminated as follows:

                  (a) Notice of Default and Consent to Action. Grantor shall
         immediately notify the Agent if a default occurs under any Collateral
         Note, and shall obtain the written consent of the Agent prior to the
         exercise of any of Grantor's remedies upon such default.

                  (b) Notices. Grantor shall promptly convey to the Agent any
         notice received by Grantor concerning any Collateral Note.

                  (c) No Further Encumbrances. Grantor shall not sell, assign,
         or grant or allow any lien to attach to any of the Collateral Notes,
         except for the security interest provided for herein.

         6. Recitals. Each Grantor represents, warrants and agrees that the
recitals set forth at the beginning of this Assignment are true.

<PAGE>

         7. No Burdensome Agreements. Each Grantor represents and warrants that
it is not a party to any contract or agreement and is not subject to any
contingent liability that does or may impair such Grantor's ability to perform
under the terms of this Assignment. Each Grantor further represents and warrants
that the execution and performance of this Assignment will not cause a default,
acceleration or other event under any other contract or agreement to which it or
any property of the Grantor is subject, and will not result in the imposition of
any charge, penalty, lien or other encumbrance against any of the Grantor's
property except in favor of the Agent for the benefit of the Lenders.

         8. Legal and Binding Agreement. Each Grantor represents and warrants
that the execution and performance of this Assignment will not violate any
judicial or administrative order or governmental law or regulation, and that
this Assignment is valid, binding and enforceable in every respect according to
its terms.

         9. No Consent Required. Each Grantor represents and warrants that its
execution, delivery and performance of this Assignment do not require the
consent of or the giving of notice to any third party including, but not limited
to, any other lender, governmental body or regulatory authority.

         10. No Default. Each Grantor represents and warrants that, as of its
execution of this Assignment, no default exists hereunder and no condition
exists which, with the giving of notice, the passing of time, or both, would
constitute such a default.

         11. Event of Default Defined. The occurrence of an event which would
constitute an Event of Default under and as defined in the 364-Day Facility or
the Multi-Year Facility shall be an Event of Default hereunder (an "Event of
Default").

         12. Remedies Upon Default. Upon the occurrence of an Event of Default
and during the continuation thereof, the Agent may pursue any or all of the
following remedies, without notice to the Grantors except as required below:

                  (a) Notice to Obligors. The Agent may notify any or all of the
         Obligors to make payments and give notices pertaining to the Collateral
         Notes directly to the Agent.

                  (b) Rights of Holder. The Agent may exercise any or all rights
         of the holder of the Collateral Notes. Without limiting the foregoing,
         the Agent may initiate any administrative or judicial proceeding that
         it may deem necessary in the course of enforcing any rights under any
         Collateral Note. Any administrative or judicial action or other action
         taken by the Agent pursuant to any Collateral Note may be taken by the
         Agent in its own name or in a Grantor's name. The Agent may enter into
         any amendment or extension of any Collateral Note and may grant any
         indulgences with respect thereto that the Agent may deem appropriate in
         the course of exercising its rights under any Collateral Note. The
         Grantors hereby appoint the Agent as their attorney-in-fact to take any
         action authorized by this Assignment upon default. The Grantors
         acknowledge that this power of attorney is coupled with an interest and
         is irrevocable.

<PAGE>

                  (c) Sale of Collateral Notes. The Agent may sell any or all of
         the Collateral Notes pursuant to the Agent's rights under the UCC. Any
         such sale may be either public or private. If public, the sale may be
         postponed by announcement at the scheduled time and place and adjourned
         to another time or place, or both. It is agreed that ten (10) days'
         notice of any sale is commercially reasonable notice thereof. Any
         public sale may be adjourned to a different time, place, or both by
         announcement at the advertised time and place of sale, without further
         publication. Any advertised sale may be canceled, in the Agent's
         discretion, either before or after the opening of bidding. The Agent
         shall transfer the Collateral Note(s) being sold to any purchaser
         thereof by endorsing the Collateral Note(s) to the purchaser's order,
         without warranty or recourse on the part of the Agent.

                  (d) Setoff. The Lenders may exercise their right of setoff as
         provided in the Credit Agreements.

                  (e) Other Remedies. The Agent may pursue any other remedies
         available under this Assignment, the Credit Agreements or any other
         Credit Document evidencing or securing the Secured Obligations or
         otherwise available to the Agent at law or equity. All such rights and
         remedies shall be cumulative and no one of them shall exclude or
         preclude the other(s).

                  (f) Application of Proceeds. Upon the occurrence and during
         the continuation of an Event of Default, any payments in respect of the
         Secured Obligations and any proceeds of the Collateral Notes, when
         received by the Agent or any of the holders of the Secured Obligations
         in cash or its equivalent, will be applied in reduction of the Secured
         Obligations in the order set forth below:

                           (i) First, to the payment of the costs and expenses
                  of the Agent (including without limitation reasonable
                  attorneys' fees) incurred in connection with the execution of
                  its duties as the Agent, in exercising or attempting to
                  exercise any right or remedy hereunder or in taking possession
                  of, protecting, preserving or disposing of any Collateral
                  Notes, and all protective advances made by the Agent with
                  respect to the Collateral Notes under or pursuant to the terms
                  hereof;

                           (ii) Second, to the payment of any fees owed to the
                  agent under either of the Credit Agreements;

                           (iii) Third, to the payment of all out-of-pocket
                  expenses (including without limitation reasonable attorneys'
                  fees) of each of the Secured Parties in connection with
                  enforcing its rights under the Credit Documents or otherwise
                  with respect to the Secured Obligations owing to such Secured
                  Party;

                           (iv) Fourth, to the Lenders, ratably, in accordance
                  with the respective amounts of the Secured Obligations
                  constituting the then aggregate unpaid

<PAGE>

                  principal amount of the Loans, together with all accrued and
                  unpaid interest thereon at such time; and

                           (v) Last, after payment in full of the Secured
                  Obligations, to the payment of the surplus, if any, to whoever
                  may be lawfully entitled to receive such surplus.

Each Grantor irrevocably waives the right to direct the application of such
payments and proceeds and acknowledges and agrees that the Agent shall have the
continuing and exclusive right to apply and reapply any and all such payments
and proceeds in the Agent's sole discretion, notwithstanding any entry to the
contrary upon any of its books and records. Payments by the Agent in respect of
(i) Secured Obligations related to the 364-Day Facility shall be made to the
agent under the 364-Day Facility for distribution to the 364-Day Lenders in
accordance with the 364-Day Facility, (ii) Secured Obligations related to the
Multi-Year Facility shall be made to the agent under the Multi-Year Facility for
distribution to the Multi-Year Lenders in accordance with the Multi-Year
Facility and (iii) Secured Obligations related to Hedging Agreements shall be
made to the party entitled thereto.

         13. Incorporation of Exhibits. All Exhibits referred to in this
Assignment are incorporated herein by this reference.

         14. Indulgence Not Waiver. The Lenders' or the Agent's indulgence in
the existence of an Event of Default hereunder or any other departure from the
terms of this Assignment shall not prejudice their rights to declare a default
or otherwise demand strict compliance with this Assignment.

         15. Cumulative Remedies. The remedies provided the Agent in this
Assignment are not exclusive of any other remedies that may be available to the
Agent under any other document or at law or equity.

         16. Amendment and Waiver in Writing. This Assignment and the provisions
hereof may not be amended, waived, modified, changed, discharged or terminated
except as set forth in Section 10.15 of each of the Credit Agreements.

         17. Assignment. This Assignment shall create a continuing security
interest in the Collateral Notes and shall be binding upon each Grantor, its
successors and assigns, and shall inure, together with the rights and remedies
of the Agent and the holders of the Secured Obligations hereunder, to the
benefit of the Agent and the holders of the Secured Obligations and their
successors and permitted assigns; provided, however, that none of the Grantors
may assign its rights or delegate its duties hereunder without the prior written
consent of the requisite Lenders under the Credit Agreements. To the fullest
extent permitted by law, each Grantor hereby releases the Agent and each holder
of the Secured Obligations, and their respective successors and assigns, from
any liability for any act or omission relating to this Assignment or the
Collateral Notes, except for any liability arising from the gross negligence or
willful misconduct of the Agent or such holder, or their respective officers,
employees or agents.

         19. Severability. If any provision of this Assignment is determined to

and the remaining provisions shall remain in full force and effect and shall be
construed without giving effect to the illegal, invalid or unenforceable
provisions.

         20. Time of Essence. Time is of the essence of this Assignment, and all

mutandis.

Loan Agreement, and all such existing liens and security interests shall remain
in full force and effect without interruption on the attachment of perfection of
any such liens and security interests.

<PAGE>

         26. Joint and Several Obligations of Grantors.

                  (a) Each of the Grantors is accepting joint and several
         liability hereunder in consideration of the financial accommodation to
         be provided by the Lenders under the Credit Agreements, for the mutual
         benefit, directly and indirectly, of each of such Grantors and in
         consideration of the undertakings of each of such Grantors to accept
         joint and several liability for the obligations of each of them.

                  (b) Each of the Grantors jointly and severally hereby
         irrevocably and unconditionally accepts, not merely as a surety but
         also as a co-debtor, joint and several liability with the other
         Grantors with respect to the payment and performance of all of the
         Secured Obligations of any such Grantor arising under this Assignment,
         the Credit Agreements or the other Credit Documents, it being the
         intention of the parties hereto that all the Secured Obligations shall
         be the joint and several obligations of each of the Grantors without
         preferences or distinction among them.

                  (c) Notwithstanding any provision to the contrary contained
         herein, in either of the Credit Agreements or in any other of the other
         Credit Documents, to the extent the obligations of a Grantor shall be
         adjudicated to be invalid or unenforceable for any reason (including,
         without limitation, because of any applicable state or federal law
         relating to fraudulent conveyances or transfers) then the obligations
         of each Grantor hereunder shall be limited to the maximum amount that
         is permissible under applicable law (whether federal or state and
         including, without limitation, the Bankruptcy Code).

         27. Authorization of Financing Statements. The Grantors authorize the
Agent to file financing statements (including renewal statements and in lieu
statements) and amendments thereof and supplements thereto with respect to the
Collateral Notes in such form and in such filing offices as the Agent reasonably
determines appropriate to perfect the security interests of the Agent under this
Assignment. Any financing statement filed by the Agent may contain a general
description of the collateral covered thereby, as permitted by the UCC, which
states that the security interest attaches to all personal property of the
debtor.

         The New Subsidiary and the Agent, for the benefit of the Lenders,
hereby agree as follows:
