ARTICLE II

THE CREDITS

SECTION 2.01. RESTRUCTURING OF HORIZON LOANS AND
CONTINENTAL LOANS. (a) When this Amended Agreement becomes
effective, without further action by any person, all
outstanding Horizon Loans and Continental Loans shall become
Loans hereunder, and shall be subject hereto, in an aggregate
principal amount equal to the aggregate principal amount of
such outstanding Horizon Loans and Continental Loans. All
such Loans hereunder shall be of the same Type, and shall have
the same Interest Period, as the corresponding Horizon Loans
and Continental Loans.

(b) On the Effective Date, each Lender whose percentage
of the total Commitments is greater under this Amended
Agreement than under the Original Credit Agreement (an
"INCREASING LENDER") shall be deemed to have purchased, and
each Lender

or lender under the Original Credit Agreement whose percentage
of the total Commitments is smaller under this Amended
Agreement (a "DECREASING LENDER") than under the Original
Credit Agreement shall be deemed to have sold and assigned, at
face value, a portion of the aggregate principal amount of
Horizon Loans and Continental Loans of each Decreasing Lender
so that, after giving effect thereto and to any new Borrowings
on the Effective Date, the aggregate principal amount of the
Loans held by each Lender shall be in the same proportion to
the aggregate unpaid principal amount of all Loans then
outstanding as the amount of such Lender's Commitment bears to
the total Commitments. Each Increasing Lender shall pay the
purchase price so determined by wire transfer of immediately
available funds to the Agent (for the account of the Decreasing
Lenders) in Dallas, Texas, not later than 1:00 p.m. on the
Effective Date.

SECTION 2.02. COMMITMENT TO MAKE LOANS. Subject to the
terms and conditions and relying upon the representations and
warranties herein set forth, each Lender agrees, severally and
not jointly, to make Loans to the Borrowers, at any time and from
time to time during the Availability Period; PROVIDED that the
aggregate principal amount at any one time outstanding of all
Loans made by such Lender (including the Loans coming into
existence pursuant to Section 2.01) shall not exceed the excess,
if any, of such Lender's Commitment set forth opposite its name
on Schedule 2.02 (as the same may be reduced from time to time
pursuant to Section 2.10) over its Letter of Credit Exposure at
such time. The Borrowers may borrow, pay or prepay and reborrow
Loans during the Availability Period, within the limits set forth
in this Section 2.02 and upon the other terms and subject to the
other conditions and limitations set forth herein.

SECTION 2.03. LOANS. (a) Each Loan shall be made as part
of a Borrowing consisting of Loans made by the Lenders ratably in
accordance with their respective Commitments; PROVIDED, HOWEVER,
that the failure of any Lender to make any Loan shall not in
itself relieve any other Lender of its obligation to lend
hereunder (it being understood, however, that no Lender shall be
responsible for the failure of any other Lender to make any Loan
required to be made by such other Lender). The Loans comprising
each Borrowing shall be in an aggregate principal amount which is
equal to (i) $2,500,000 or any greater integral multiple of
$1,000,000 in the case of Eurodollar Loans and (ii) $1,000,000 or
any greater integral multiple of $100,000 in the case of ABR
Loans (or, in either case, an aggregate principal amount equal to
the remaining balance of the Commitments).

(b) A particular Borrowing shall consist solely of ABR
Loans or Eurodollar Loans, as the Borrowers may request pursuant
to Section 2.04. Each Lender may at its option fulfill its
Commitment with respect to any Eurodollar Loan by causing any
domestic or foreign branch or Affiliate of such Lender to make
such Loan; PROVIDED that any exercise of such option shall not
affect the obligation of the Borrowers to repay such Loan in
accordance with the terms of this Amended Agreement and the
applicable Note. Borrowings by the Borrowers of more than one
Type and Eurodollar Loans bearing interest for more than one
specific Interest Period may be outstanding at the same time;
PROVIDED, HOWEVER, that Borrowers shall not be entitled to

request any Borrowing which, if made, would result in an
aggregate of more than eight separate Eurodollar Loans of any
Lender being outstanding hereunder at any one time. For purposes
of the foregoing, Loans having different Interest Periods,
regardless of whether they commence on the same date, shall be
considered separate Loans.

(c) Subject to Section 2.03(g), each Lender shall make a
Loan in the amount of its pro rata portion, as determined under
Section 2.15, of each Borrowing hereunder on the proposed date
thereof by wire transfer of immediately available funds to the
Agent in Dallas, Texas, not later than 1:00 p.m., Dallas time,
and the Agent shall by 3:00 p.m., Dallas time, credit the amounts
so received to the joint general deposit account of the Borrowers
with the Agent or, if a Borrowing shall not occur on such date
because any condition precedent herein specified shall not have
been met, return the amounts so received to the respective
Lenders.

(d) If the Agent has not received from the Borrowers the
payment required by Section 2.20(g) by 12:30 p.m., Dallas time,
on the date on which the Issuing Bank has notified the Borrowers
and the Agent that payment of a draft presented under the
applicable Letter of Credit will be made, as provided in
Section 2.20(g), the Agent will promptly notify the Issuing Bank
and each Lender of the corresponding Letter of Credit
Disbursement and, in the case of each Lender, its pro rata
portion, as determined under Section 2.15, of such Letter of
Credit Disbursement. Not later than 2:00 p.m., Dallas time, on
such date, each Lender shall make available its pro rata portion
of such Letter of Credit Disbursement, in Federal or other funds
immediately available in Dallas, to the Agent at its address set
forth in Section 9.01, and the Agent will promptly make such
funds available to the Issuing Bank. The Agent will promptly
remit to each Lender that shall have made such funds available
its pro rata portion, as determined under Section 2.15, of any
amounts subsequently received by the Agent from the Borrowers in
respect of such Letter of Credit Disbursement.

(e) Unless the Agent shall have received notice from a
Lender prior to any Borrowing, or prior to the time of any
required payment by such Lender in respect of a Letter of Credit
Disbursement, that such Lender will not make available to the
Agent such Lender's portion of such Borrowing or payment, the
Agent may assume that such Lender has made such portion available
to the Agent on the date of such Borrowing or payment in
accordance with Section 2.03(c) or (d), as applicable, and the
Agent may, in reliance upon such assumption, make available to
the Borrowers or the Issuing Bank, as applicable, on such date a
corresponding amount. If and to the extent that such Lender
shall not have made such portion available to the Agent, such
Lender and the Borrowers agree to repay to the Agent forthwith on
demand such corresponding amount together with interest thereon,
for each day from the date such amount is made available to the
Borrowers or the Issuing Bank (or, if the Agent and the Issuing
Bank are the same person, from the date of such payment in
respect of a Letter of Credit Disbursement), as applicable, until
the date such amount is repaid to the Agent at, (i) in the case
of Borrowers, the interest rate applicable thereto pursuant to
Section 2.07 or 2.20(g), as applicable, and (ii) in the case of
such Lender, the Federal Funds Effective Rate. If such Lender
shall repay to the Agent such corresponding amount in respect of
a Borrowing, such amount shall constitute such Lender's Loan as
part of such Borrowing for the purposes of this Amended
Agreement.

(f) Notwithstanding any other provision of this Amended
Agreement, the Borrowers shall not be entitled to request any
Borrowing if the Interest Period requested with respect thereto
would end after the Maturity Date. Any Borrowing which cannot be
refinanced as a Eurodollar Borrowing by reason of the preceding
sentence shall be automatically converted at the end of the
Interest Period in effect for such Borrowing into an ABR
Borrowing.

(g) The Borrowers may refinance all or any part of any
Borrowing with a Borrowing of the same or a different Type, upon
the terms and subject to the conditions and limitations set forth
in this Amended Agreement. Any Borrowing or part thereof so
refinanced shall be deemed to be repaid or prepaid in accordance
with Section 2.05 or 2.11, as applicable, with the proceeds of a
new Borrowing and the proceeds of such new Borrowing (to the
extent they do not exceed the principal amount of the Borrowing
being refinanced) shall not be paid by the Lenders to the Agent
or by the Agent to the Borrowers pursuant to Section 2.03(c).

SECTION 2.04. NOTICE OF BORROWINGS. The Borrowers shall
give the Agent written or telecopy notice (or telephone notice
promptly confirmed in writing or by telecopy) (a) in the case of
a Eurodollar Borrowing, not later than 10:00 a.m., Dallas time,
three Business Days before a proposed borrowing and (b) in the
case of an ABR Borrowing, not later than 11:00 a.m., Dallas time,
on the day of the proposed borrowing. Such notice shall be
irrevocable and shall in each case refer to this Amended
Agreement and specify (i) whether the Borrowing then being
requested is to be a Eurodollar Borrowing or an ABR Borrowing;
(ii) the date of such Borrowing (which shall be a Business Day)
and the amount thereof; and (iii) if such Borrowing is to be a
Eurodollar Borrowing, the Interest Period with respect thereto.
If no election as to the Type of Borrowing is specified in any
such notice, then the requested Borrowing shall be an
ABR Borrowing. If no Interest Period with respect to any
Eurodollar Borrowing is specified in any such notice, then the
Borrowers shall be deemed to have selected an Interest Period of
one month's duration. If the Borrowers shall fail to give notice
in accordance with this Section 2.04 of their election to
refinance a Borrowing prior to the end of the Interest Period in
effect for such Borrowing, then the Borrowers shall (unless such
Borrowing is repaid at the end of such Interest Period) be deemed
to have given notice of an election to refinance such Borrowing
with an ABR Borrowing. The Agent shall promptly advise the
Lenders of any notice given pursuant to this Section 2.04 and of
each Lender's portion of the requested Borrowing.

SECTION 2.05. NOTES; REPAYMENT OF LOANS. The Loans made by
each Lender shall be evidenced by a Note duly executed and
delivered on behalf of the Borrowers, dated the Effective Date,
in substantially the form attached hereto as Exhibit A, with the
blanks appropriately filled in, payable to the order of such
Lender in a principal amount equal to such Lender's Commitment.
The outstanding principal balance of each Loan, as evidenced by
the Note, shall be payable on the last day of the Interest Period
applicable to such Loan and on the Maturity Date. Each Note
shall bear interest from the Effective Date on the outstanding
principal balance thereof as set forth in Section 2.07. Each
Lender shall, and is hereby authorized by the Borrowers to,
endorse on the schedule attached to the Note delivered to such
Lender (or on a continuation of such schedule attached to such
Note and made a part thereof), or otherwise to record in such
Lender's internal records, an appropriate notation evidencing

the date and amount of each applicable Loan from such Lender, each
payment and prepayment of principal of any such Loan, each
payment of interest on any such Loan and the other information
provided for on such schedule; PROVIDED, HOWEVER, that the
failure of any Lender to make such a notation or any error
therein shall not affect the obligation of the Borrowers to repay
the Loans made by such Lender in accordance with the terms of
this Amended Agreement and the Note.

SECTION 2.06. FEES. (a) The Borrowers shall pay to the
Agent for the account of each Lender, on the last day of March,
June, September and December in each year, and on the date on
which the Commitment of such Lender shall be terminated as
provided herein, a commitment fee (a "COMMITMENT FEE") on the
average daily unused amount of the Commitment of such Lender
during the preceding quarter (or shorter period commencing with
the Effective Date or ending with the date on which the
Commitment of such Lender shall be terminated), equal to the
Commitment Rate per annum. The "unused amount" of the Commitment
of a Lender on any date means the amount of such Lender's
Commitment on such date, less the sum of its outstanding Loans on
such date and its Letter of Credit Exposure on such date. All
Commitment Fees shall be computed on the basis of the actual
number of days elapsed in a year of 360 days. The Commitment Fee
due to each Lender shall commence to accrue from the Effective
Date and shall cease to accrue on the date on which the
Commitment of such Lender shall be terminated as provided herein.

(b) The Borrowers agree to pay to the Agent, for its own
account, the fees set forth in the Fee Letter dated August 25,
1995, as amended (the "FEE LETTER"), among the Agent and the
Borrowers, in the amounts and on the dates provided in the Fee
Letter. The annual administration fee provided in the Fee Letter
shall by payable in advance on each anniversary of the Closing
Date prior to the Maturity Date. Such fees shall be in addition
to reimbursement of the Agent's reasonable out-of-pocket
expenses.

(c) All Fees shall be paid on the dates due, in immediately
available funds. Once paid, none of the Fees shall be refundable
under any circumstances.

SECTION 2.07. INTEREST ON LOANS. (a) Subject to the
provisions of Section 2.08, each Loan comprising an ABR Borrowing
shall bear interest for each day from the date such Loan is made
until it becomes due (computed on the basis of the actual number
of days elapsed over a year of 365 or 366 days, as the case may
be, when determined by reference to the Prime Rate and over a
year of 360 days at all other times unless such calculation would
result in a usurious rate, in which case such interest shall be
computed on the basis of the actual number of days elapsed over a
year of 365 or 366 days, as the case may be) at a rate per annum
equal to the Alternate Base Rate, but in no event to exceed the
Highest Lawful Rate.

(b) Subject to the provisions of Section 2.08, each Loan
comprising a Eurodollar Borrowing shall bear interest for each
day from the date such Loan is made until it becomes due
(computed on the basis of the actual number of days elapsed over
a year of 360 days unless such calculation would result in a
usurious rate, in which case such interest shall be computed on
the basis of the actual number of days elapsed over a year of 365
or 366 days, as

the case may be) at a rate per annum equal to the Adjusted LIBO Rate
for the Interest Period in effect for such Borrowing, plus the Eurodollar
Margin, but in no event to exceed the Highest Lawful Rate.

(c) Subject to the applicable terms and conditions of
Section 1.01, each Pricing Period shall commence on (and include)
the date of delivery to the Agent of Required Financial
Statements demonstrating that such period has commenced (or, in
the case of a Level VI Pricing Period, on the first date on which
Horizon has failed to deliver any of the Required Financial
Statements when due in accordance with Section 5.04) and shall
terminate on (and exclude) the earlier of (i) the date of
delivery to the Agent of any subsequent Required Financial
Statements demonstrating that such period has terminated and
(ii) the first date on which the Borrowers have failed to deliver
any of its Required Financial Statements when due in accordance
with Section 5.04; PROVIDED that, in the case of a Level VI
Pricing Period arising solely due to Horizon's failure to deliver
any Required Financial Statements, such period shall terminate on
(and exclude) the date of delivery to the Agent of such Required
Financial Statements.

(d) Interest on each Loan shall be payable on the Interest
Payment Dates applicable to such Loan, except as otherwise
provided in this Amended Agreement. The applicable Alternate
Base Rate or Adjusted LIBO Rate for each Interest Period or day
within an Interest Period, as the case may be, shall be
determined by the Agent, and such determination shall be
conclusive absent manifest error.

SECTION 2.08. DEFAULT INTEREST. If the Borrowers shall
default in the payment of the principal of or interest on any
Loan or any other amount becoming due under this Amended
Agreement or any other Loan Document, by acceleration or
otherwise, interest shall accrue, to the extent permitted by law,
on such defaulted amount during the period from (and including)
the date of such default to (but not including) the date of
actual payment (after as well as before judgment) at a rate per
annum (computed on the basis of the actual number of days elapsed
over a year of 365 or 366 days, as the case may be, when
determined by reference to the Prime Rate and over a year of
360 days at all other times unless such calculation would result
in a usurious rate, in which case such interest shall be computed
on the basis of the actual number of days elapsed over a year of
365 or 366 days, as the case may be) equal to the rate applicable
to ABR Loans during such period pursuant to Section 2.07, plus
2.00%, but in no event to exceed the Highest Lawful Rate. The
Borrowers shall pay all such accrued but unpaid interest from
time to time upon demand.

SECTION 2.09. ALTERNATE RATE OF INTEREST. In the event,
and on each occasion, that on the Business Day prior to the
commencement of any Interest Period for a Eurodollar Borrowing
the Agent shall have determined that dollar deposits in the
principal amounts of the Loans comprising such Borrowing are not
generally available in the applicable interbank market, or that
the rates at which such dollar deposits are being offered will
not adequately and fairly reflect the cost to any Lender of
making or maintaining its Eurodollar Loan during such Interest
Period, or that reasonable means do not exist for ascertaining
the Adjusted LIBO Rate, the Agent shall, as soon as practicable
thereafter, give written or telecopy notice of such

determination to the Borrowers and the Lenders. In the event of any
such determination, any request by the Borrowers for a Eurodollar
Borrowing pursuant to Section 2.04 shall, until the Agent shall
have advised the Borrowers and the Lenders that the circumstances
giving rise to such notice no longer exist, be deemed to be a
request for an ABR Borrowing. Each determination by the Agent
hereunder shall be conclusive absent manifest error.

SECTION 2.10. REDUCTION OF COMMITMENTS; EXTENSION OF
COMMITMENTS. (a) The Commitments shall be reduced permanently
(i) by $50,000,000 at 5:00 p.m., Dallas time, on each of the
second and third anniversaries of the later of (A) the Effective
Date and (B) the most recent Extension Date, if any, and (ii) by
$100,000,000 at 5:00 p.m., Dallas time, on the fourth anniversary
of such later date. The Commitments shall be automatically
terminated at 5:00 p.m., Dallas time, on the Maturity Date.

(b) Horizon shall have the option to request the extension
of the Maturity Date by one year, on an annual basis in
accordance with this Section 2.10(b), so that a five-year
Availability Period would be maintained. In the event that
Horizon desires to extend the maturity of the Facility, Horizon
shall give notice of such request to the Agent not less than 90
days, and not more than 120 days, before the date (the "PROPOSED
EXTENSION DATE") which is four years prior to the existing
Maturity Date. The Agent shall give the other Lenders prompt
notice of the receipt of any such request. Such request shall be
deemed granted if, and only if, the Agent shall have received
written notice of the approval of such proposed extension, by
September 30 immediately following the Proposed Extension Date,
from each Lender, except for any Lender which is replaced by
Horizon as provided in this Section 2.10(b); otherwise, the
existing Maturity Date shall not be extended. Any such Lender
which shall have failed to give such notice of approval by such
September 30 is referred to herein as a "DISSENTING LENDER".
Horizon shall have the right to replace any Dissenting Lender by
causing such Lender to transfer and assign all its interests,
rights and obligations under this Amended Agreement to another
financial institution pursuant to Section 2.19 (a "REPLACEMENT
LENDER") by October 15 immediately following such Proposed
Extension Date; PROVIDED that the Consenting Lenders shall have
given written notice to the Agent of the approval of the proposed
extension by such September 30. Horizon may request an extension
of the Maturity Date pursuant to this Section 2.10(b) in each
year, commencing in 1996; PROVIDED that, except in the case of
any such request in 1996, it shall have requested and received an
extension of the Maturity Date pursuant to this Section 2.10(b)
in the previous year. The Agent shall give Horizon and each
Lender prompt written notice of whether any proposed extension
has been granted or denied. Any request for an extension of the
Maturity Date that has been granted in accordance with the
procedure set forth in this Section 2.10(b) is referred to herein
as an "APPROVED EXTENSION" and the Proposed Extension Date
relating to such Approved Extension is referred to herein as an
"EXTENSION DATE".

(c) Upon at least five Business Days' prior irrevocable
written or telecopy notice to the Agent, the Borrowers may at any
time in whole permanently terminate, or from time to time in part
permanently reduce, the Commitments; PROVIDED, HOWEVER, that each
partial reduction of the Commitments shall be in an aggregate
principal amount which is an integral multiple of $1,000,000.

(d) Each reduction in the Commitments shall be made ratably
among the Lenders in accordance with their respective applicable
Commitments. On the date of each termination or reduction of the
Commitments, the Borrowers shall pay to the Agent, for the
account of the Lenders, the Commitment Fees on the amount of the
Commitments so terminated or reduced accrued to the date of such
termination or reduction.

SECTION 2.11. REPAYMENTS AND PREPAYMENTS. (a) To the
extent not previously paid, all Borrowings shall be due and
payable on the Maturity Date.

(b) In the event and on each occasion that the sum of (i) the
aggregate outstanding principal amount of the Loans and (ii) the Letter
of Credit Exposure exceeds the aggregate amount of the Commitments at
such time, the Borrowers shall immediately prepay Loans (and, to the
extent that the amount of such excess is greater than the aggregate
principal amount of outstanding Loans, provide cash collateral in respect
of the Letter of Credit Exposure pursuant to Section 2.20(k) and thereupon
such cash shall be deemed to reduce the Letter of Credit Exposure for
purposes of this Section 2.11(b)) in an aggregate principal amount equal
to such excess.

(c) Subject to Section 2.11(d), the Borrowers shall have
the right at any time and from time to time to prepay any
Borrowing, in whole or in part, upon prior written or telecopy
notice (or telephone notice promptly confirmed by written or
telecopy notice) to the Agent (i) in the case of any prepayment
of Eurodollar Loans, at least three Business Days in advance of
the proposed prepayment and (ii) in the case of any prepayment of
ABR Loans, by 11:00 a.m., Dallas time, on the day of the proposed
prepayment; PROVIDED, HOWEVER, that (A) each partial prepayment
of Eurodollar Loans under this Section 2.11(c) shall be in an
aggregate principal amount equal to an integral multiple of
$1,000,000, (B) each partial prepayment of ABR Loans under this
Section 2.11(c) shall be in an aggregate principal amount equal
to an integral multiple of $100,000, (C) a partial prepayment of
a Eurodollar Borrowing under this Section 2.11(c) shall not be
made that would result in the remaining aggregate outstanding
principal amount thereof being less than $2,500,000 and (D) a
partial prepayment of an ABR Borrowing under this Section 2.11(c)
shall not be made that would result in the remaining aggregate
outstanding principal amount thereof being less than $1,000,000.
Each notice of prepayment shall specify the prepayment date, the
Type, the Interest Period of the Borrowing to be prepaid (in the
case of a Eurodollar Borrowing) and the principal amount thereof
to be prepaid, shall be irrevocable and shall commit the
Borrowers to prepay such Borrowing by the amount stated therein
on the date stated therein.

(d) Each payment of Borrowings pursuant to this
Section 2.11 shall be accompanied by accrued interest on the
principal amount paid to but excluding the date of payment. All
payments under this Section 2.11 shall be subject to
Section 2.14, but otherwise shall be without premium or penalty.
Any mandatory prepayment of Loans pursuant to Section 2.11(b)
shall be applied to prepay all ABR Loans before any Eurodollar
Loans are prepaid.

SECTION 2.12. RESERVE REQUIREMENTS; CERTAIN CHANGES IN CIRCUMSTANCES.
(a) Notwithstanding any other provision herein, if after the date of this
Amended Agreement

any change in applicable law or regulation 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 any Lender of the
principal of or interest on any Eurodollar Loan made by such Lender or any
Fees or other amounts payable hereunder (other than changes in respect of
taxes imposed on the overall net income of such Lender by the jurisdiction
in which such Lender has its principal office or by any political
subdivision or taxing authority therein), or shall impose, modify or deem
applicable any reserve, special deposit or similar requirement against assets
of, deposits with or for the account of or credit extended by such Lender
(except any such reserve requirement which is reflected in the Adjusted
LIBO Rate) or shall impose on such Lender or the applicable interbank market
any other condition affecting this Amended Agreement or Eurodollar Loans
made by such Lender, and the result of any of the foregoing shall be to
increase the cost to such Lender of making or maintaining any Eurodollar
Loan or to reduce the amount of any sum received or receivable by such
Lender hereunder or under the Notes (whether of principal, interest or
otherwise) or Letters of Credit by an amount deemed by such Lender to be
material, then from time to time the Borrowers shall pay to such Lender
upon demand such additional amount or amounts as will compensate such
Lender for such additional costs incurred or reduction suffered with respect
to the Facility.

(b) If any Lender shall have determined that the adoption
after the date hereof of any law, rule, regulation, agreement or
guideline regarding capital adequacy, or any change in any of the
foregoing or in the interpretation or administration of any of
the foregoing by any Governmental Authority, central bank or
comparable agency charged with the interpretation or
administration thereof, or compliance by any Lender (or any
lending office of such Lender) or any Lender's holding company
with any request or directive regarding capital adequacy (whether
or not having the force of law) of any such authority, central
bank or comparable agency, has or would have the effect of
reducing the rate of return on such Lender's capital or on the
capital of such Lender's holding company, if any, as a
consequence of this Amended Agreement, the Letters of Credit or
the Loans made by such Lender pursuant hereto to a level below
that which such Lender or such Lender's holding company could
have achieved but for such adoption, change or compliance (taking
into consideration such Lender's policies and the policies of
such Lender's holding company with respect to capital adequacy)
by an amount deemed by such Lender to be material, then from time
to time the Borrowers shall pay to such Lender upon demand such
additional amount or amounts as will compensate such Lender or
such Lender's holding company for any such reduction suffered
with respect to the Facility.

(c) A certificate of each Lender setting forth such amount
or amounts as shall be necessary to compensate such Lender or its
holding company as specified in paragraph (a) or (b) above, as
the case may be, shall be delivered to the Borrowers and shall be
conclusive absent manifest error. The Borrowers shall pay each
Lender the amount shown as due on any such certificate delivered
by it within 10 days after its receipt of the same.

(d) Failure on the part of any Lender to demand
compensation for any increased costs or reduction in amounts
received or receivable or reduction in return on capital with
respect to any period shall not constitute a waiver of such
Lender's right to demand compensation with

respect to any other period. The protection of this Section 2.12
shall be available to each Lender regardless of any possible contention
of the invalidity or inapplicability of the law, rule, regulation,
guideline or other change, condition or circumstances which shall
have occurred or been imposed.

(e) Any Lender claiming compensation for any additional
amounts pursuant to this Section 2.12 shall use reasonable
efforts (consistent with legal and regulatory restrictions) to
change the jurisdiction of its applicable lending office if the
making of such change would avoid the need for or reduce the
amount of any such additional amounts or additional amounts that
may thereafter accrue and that would not be otherwise
disadvantageous to such Lender in its sole judgment.

(f) No Lender shall be entitled to compensation under this
Section 2.12 for any costs incurred or reductions suffered with
respect to any date unless such Lender shall have notified the
Borrowers that it will demand compensation for such costs or
reductions not more than 90 days after the later of (i) such date
and (ii) the date on which such Lender becomes aware of such
costs or reductions.

SECTION 2.13. CHANGE IN LEGALITY. (a) Notwithstanding any
other provision herein, if any change in any law or regulation or
in the interpretation thereof by any Governmental Authority
charged with the administration or interpretation thereof shall
make it unlawful for any Lender to make or maintain any
Eurodollar Loan or to give effect to its obligations as
contemplated hereby with respect to any Eurodollar Loan, then, by
written or telecopy notice to the Borrowers and to the Agent,
such Lender may:

(i) declare that Eurodollar Loans will not thereafter
be made by such Lender hereunder, whereupon any request by
the Borrowers for a Eurodollar Borrowing shall, as to such
Lender only, be deemed a request for an ABR Loan unless such
declaration shall be subsequently withdrawn; and

(ii) require that all outstanding Eurodollar Loans
made by it be converted to ABR Loans, in which event all
such Eurodollar Loans shall be automatically converted to
ABR Loans as of the effective date of such notice as
provided in Section 2.13(b).

In the event that any Lender shall exercise its rights under
clause (i) or (ii) above, all payments and prepayments of
principal which would otherwise have been applied to repay the
Eurodollar Loans that would have been made by such Lender or the
converted Eurodollar Loans of such Lender shall instead be
applied to repay the ABR Loans made by such Lender in lieu of, or
resulting from the conversion of, such Eurodollar Loans.

(b) For purposes of this Section 2.13, a notice to the
Borrowers by any Lender shall be effective as to each Eurodollar
Loan, if lawful, on the last day of the Interest Period currently
applicable to such Eurodollar Loan; in all other cases such
notice shall be effective on the date of receipt by each
Borrower.

(c) In the event of a change in any law or regulation that
enables any Lender to exercise its rights under clause (i) or
(ii) of Section 2.13(a), such Lender shall use reasonable efforts
(consistent with legal and regulatory restrictions) to change the
jurisdiction of its applicable lending office if the making of
such change would avoid the need for such exercise of rights and
would not be otherwise disadvantageous to such Lender in its sole
judgment.

SECTION 2.14. INDEMNITY. To the fullest extent permitted
under applicable law, the Borrowers shall indemnify each Lender
against any loss or expense which such Lender may sustain or
incur as a consequence of (a) any failure by the Borrowers to
fulfill on the date of any borrowing hereunder the applicable
conditions set forth in Article IV, (b) any failure by the
Borrowers to borrow or to refinance or continue any Loan
hereunder after irrevocable notice of such borrowing or
refinancing has been given pursuant to Section 2.04, (c) any
payment or prepayment of a Eurodollar Loan required by any other
provision of this Amended Agreement or otherwise made or deemed
made on a date other than the last day of the Interest Period
applicable thereto, (d) any default in payment or prepayment of
the principal amount of any Loan or any part thereof or interest
accrued thereon, as and when due and payable (at the due date
thereof, whether by scheduled maturity, acceleration, irrevocable
notice of prepayment or otherwise) or (e) the occurrence of any
Event of Default, including, in each such case, any loss or
reasonable expense sustained or incurred or to be sustained or
incurred in liquidating or employing deposits from third parties
acquired to effect or maintain such Loan or any part thereof as a
Eurodollar Loan. Such loss or reasonable expense shall include
an amount equal to the excess, if any, as reasonably determined
by such Lender, of (i) its cost of obtaining the funds for the
Loan being paid, prepaid or not borrowed, refinanced or not paid
or prepaid (assumed to be the Adjusted LIBO Rate applicable
thereto) for the period from the date of such payment, prepayment
or failure to borrow, refinance or failure to pay or prepay to
the last day of the Interest Period for such Loan (or, in the
case of a failure to borrow or refinance, the Interest Period for
such Loan which would have commenced on the date of such failure)
over (ii) the amount of interest (as reasonably determined by
such Lender) that would be realized by such Lender in reemploying
the funds so paid, prepaid or not borrowed or refinanced for such
period or Interest Period, as the case may be. A certificate of
any Lender setting forth any amount or amounts which such Lender
is entitled to receive pursuant to this Section 2.14 shall be
delivered to the Borrowers and shall be conclusive absent
manifest error. The Borrowers shall pay each Lender the amount
shown as due on any such certificate delivered by it within
10 days after its receipt of the same.

SECTION 2.15. PRO RATA TREATMENT. Except as required under
Section 2.13, each Borrowing, each payment or prepayment of
principal of any Borrowing, each payment of interest on the
Loans, each payment of the Commitment Fees, each reduction of the
Commitments, each refinancing of any Borrowing with a Borrowing
of any Type and each Letter of Credit Disbursement shall be
allocated pro rata among the Lenders in accordance with their
respective Commitments (or, in the case of any Lender which has
not funded its Commitment as required hereunder, in accordance
with the aggregate unpaid principal amount of its Loans). Each
Lender agrees that in computing such Lender's portion of any
Borrowing to be made hereunder, the Agent may, in its discretion,
round each Lender's percentage of such Borrowing, computed in
accordance with Schedule 2.02, to the next higher or lower

whole dollar amount. The Agent will promptly distribute in lawful
money of the United States and in immediately available funds to
each Lender its pro rata portion, as determined under this
Section 2.15, of each payment received by the Agent for the
account of the Lenders.

SECTION 2.16. SHARING OF SETOFFS. Each Lender agrees that
if it shall, through the exercise of a right of banker's lien,
setoff or counterclaim against either Borrower, 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, obtain payment (voluntary or involuntary) in
respect of any Loan or Loans as a result of which the aggregate
unpaid principal portion of its Loans shall be proportionately
less than the aggregate unpaid principal portion of the Loans of
any other Lender, it shall be deemed simultaneously to have
purchased from such other Lender at face value, and shall
promptly pay to such other Lender the purchase price for, a
participation in such Loans of such other Lender, so that the
aggregate unpaid principal amount of the Loans and participations
in Loans held by each Lender shall be in the same proportion to
the aggregate unpaid principal amount of all Loans then
outstanding as the principal amount of its Loans prior to such
exercise of banker's lien, setoff or counterclaim or other event
was to the principal amount of all Loans outstanding prior to
such exercise of banker's lien, setoff or counterclaim or other
event; PROVIDED, HOWEVER, that, if any such purchase or purchases
or adjustments shall be made pursuant to this Section 2.16 and
the payment giving rise thereto shall thereafter be recovered,
such purchase or purchases or adjustments shall be rescinded to
the extent of such recovery and the purchase price or prices or
adjustment restored without interest. Each Borrower expressly
consents to the foregoing arrangements and agrees that any Lender
holding a participation in a Loan deemed to have been so
purchased may exercise any and all rights of banker's lien,
setoff or counterclaim with respect to any and all moneys owing
by such Borrower to such Lender by reason thereof as fully as if
such Lender had made a Loan directly to such Borrower in the
amount of such participation.

SECTION 2.17. PAYMENTS. (a) The Borrowers shall make each
payment (including principal of or interest on any Borrowing or
any Fees or other amounts) hereunder or under any other Loan
Document not later than 12:00 (noon), Dallas time, on the date
when due in dollars to the Agent at its offices at ▇▇▇ ▇▇▇▇
▇▇▇▇▇▇, ▇▇▇▇ ▇▇▇▇▇, ▇▇▇▇▇▇, ▇▇▇▇▇ ▇▇▇▇▇, in immediately available
funds. Any such payment received after such time on any date
shall be deemed made on the next Business Day.

(b) Whenever any payment (including principal of or
interest on any Borrowing or any Fees or other amounts) hereunder
or under any other Loan Document shall become due, or otherwise
would occur, on a day that is not a Business Day, such payment
may be made on the next succeeding Business Day, and such
extension of time shall in such case be included in the
computation of interest or Fees, if applicable.

SECTION 2.18. TAXES. (a) Any and all payments by the
Borrowers hereunder shall be made, in accordance with
Section 2.17, free and clear of and without deduction for any and
all present or future taxes, levies, imposts, deductions, charges
or withholdings, and all

liabilities with respect thereto, EXCLUDING (i) taxes imposed on the net
income of the Agent or any Lender (or any transferee or assignee thereof,
including a participation holder (any such entity being called a
"TRANSFEREE")) and (ii) franchise taxes imposed on the Agent or any Lender
(or Transferee), in each case by the jurisdiction under the laws of which the
Agent or any Lender (or Transferee) is organized or any political subdivision
thereof (all such nonexcluded taxes, levies, imposts, deductions, charges,
withholdings and liabilities, collectively or individually, "TAXES"). If the
Borrowers shall be required to deduct any Taxes from or in respect of any sum
payable hereunder to any Lender (or Transferee) or the Agent, (A) the sum
payable shall be increased by the amount (an "ADDITIONAL AMOUNT") necessary
so that after making all required deductions (including deductions applicable
to additional sums payable under this Section 2.18) such Lender (or
Transferee) or the Agent, as the case may be, shall receive an amount equal
to the sum it would have received had no such deductions been made, (B) the
Borrowers shall make such deductions and (C) the Borrowers shall pay the full
amount deducted to the relevant taxing authority or other Governmental
Authority in accordance with applicable law.

(b) In addition, to the fullest extent permitted under
applicable law, the Borrowers agree to indemnify the Agent, the
Issuing Bank and each Lender from, and hold them harmless
against, and to pay to the relevant Governmental Authority in
accordance with applicable law, any current or future stamp or
documentary taxes or any other excise or property taxes,
assessments, charges or similar levies made by any Governmental
Authority which arise from any payment made hereunder by the
Borrowers or from the execution and delivery by the Borrowers of
this Amended Agreement or any other Loan Document or otherwise
with respect to the Facility (hereinafter referred to as "OTHER
TAXES").

(c) To the fullest extent permitted under applicable law,
the Borrowers will indemnify each Lender (or Transferee) and the
Agent for the full amount of Taxes and Other Taxes paid by such
Lender (or Transferee) or the Agent, as the case may be, and any
liability (including penalties, interest and expenses) arising
therefrom or with respect thereto, whether or not such Taxes or
Other Taxes were correctly or legally asserted by the relevant
Governmental Authority, in each case to the extent relating to
the Facility. A certificate as to the amount of such payment or
liability prepared by a Lender (or Transferee), or the Agent on
its behalf, or by the Agent on its own behalf, shall be
conclusive absent manifest error. Such indemnification shall be
made within 30 days after the date any Lender (or Transferee) or
the Agent, as the case may be, makes written demand therefor.

(d) If any Lender (or Transferee) or the Agent shall become
aware that it is entitled to claim a refund in respect of Taxes
or Other Taxes as to which it has been indemnified by the
Borrowers, or with respect to which the Borrowers have paid
additional amounts, pursuant to this Section 2.18, it shall
promptly notify the Borrowers of the availability of such refund
claim and shall, within 30 days after receipt of a request by the
Borrowers, make a claim to such Governmental Authority for such
refund at the Borrowers' expense. If any Lender (or Transferee)
or the Agent receives a refund (including pursuant to a claim for
refund made pursuant to the preceding sentence) in respect of any
Taxes or Other Taxes as to which it has been indemnified by the
Borrowers, or with respect to which the Borrowers have paid

additional amounts, pursuant to this Section 2.18, it shall
within 30 days from the date of such receipt pay over such refund
to the Borrowers (but only to the extent of indemnity payments
made, or additional amounts paid, by the Borrowers under this
Section 2.18 with respect to the Taxes or Other Taxes giving rise
to such refund), net of all out-of-pocket expenses of such Lender
(or Transferee) or the Agent and without interest (other than
interest paid by the relevant Governmental Authority with respect
to such refund); PROVIDED, HOWEVER, that the Borrowers, upon the
request of such Lender (or Transferee) or the Agent, agree to
repay the amount paid over to the Borrowers (plus penalties,
interest or other charges) to such Lender (or Transferee) or the
Agent in the event such Lender (or Transferee) or the Agent is
required to repay such refund to such Governmental Authority.

(e) As soon as practicable after the date of any payment of
Taxes or Other Taxes by the Borrowers to the relevant
Governmental Authority, the Borrowers will deliver to the Agent,
at its address referred to in Section 9.01, the original or a
certified copy of a receipt evidencing payment thereof.

(f) To the fullest extent permitted under applicable law,
the provisions of this Section 2.18 shall remain operative and in
full force and effect regardless of the expiration of the term of
this Amended Agreement, the consummation of the transactions
contemplated hereby, the repayment of any of the Loans, the
invalidity or unenforceability of any term or provision of this
Amended Agreement or any other Loan Document, or any
investigation made by or on behalf of the Agent or any Lender.

(g) Each Lender (or Transferee) that is organized under the
laws of a jurisdiction other than the United States, any State
thereof or the District of Columbia (a "NON-U.S. LENDER") shall
deliver to the Borrowers and the Agent two copies of either
United States Internal Revenue Service Form 1001 or Form 4224,
or, in the case of a Non-U.S. Lender claiming exemption from U.S.
Federal withholding tax under Section 871(h) or 881(c) of the
Code with respect to payments of "portfolio interest", a Form W-
8, or any subsequent versions thereof or successors thereto (and,
if such Non-U.S. Lender delivers a Form W-8, a certificate
representing that such Non-U.S. Lender is not a bank for purposes
of Section 881(c) of the Code, is not a 10-percent shareholder
(within the meaning of Section 871(h)(3)(B) of the Code) of
either Borrower and is not a controlled foreign corporation
related to either Borrower (within the meaning of Section
864(d)(4) of the Code), properly completed and duly executed by
such Non-U.S. Lender) claiming complete exemption from, or
reduced rate of, U.S. Federal withholding tax on payments by the
Borrowers under this Amended Agreement and the other Loan
Documents. Such forms shall be delivered by each Non-U.S. Lender
on or before the Effective Date (or, in the case of a Transferee
that is a participation holder, on or before the date such
participation holder becomes a Transferee hereunder) and on or
before the date, if any, such Non-U.S. Lender changes its
applicable lending office by designating a different lending
office (a "NEW LENDING OFFICE"). In addition, each Non-U.S.
Lender shall deliver such forms promptly upon the obsolescence or
invalidity of any form previously delivered by such Non-U.S.
Lender. Notwithstanding any other provision of this
Section 2.18(g), a Non-U.S. Lender shall not be required to
deliver any form pursuant to this Section 2.18(g) that such Non-
U.S. Lender is not legally able to deliver.

(h) The Borrowers shall not be required to indemnify any
Non-U.S. Lender, or to pay any additional amounts to any Non-U.S.
Lender, in respect of United States Federal withholding tax
pursuant to Section 2.18 to the extent that (i) the obligation to
pay such additional amounts would not have arisen but for a
failure by such Non-U.S. Lender to comply with the provisions of
Section 2.18(g) or (ii) the obligation to withhold amounts with
respect to United States Federal withholding tax existed on the
date such Non-U.S. Lender became a party to this Amended
Agreement (or, in the case of a Transferee that is a
participation holder, on the date such participation holder
became a Transferee hereunder) or, with respect to payments to a
New Lending Office, the date such Non-U.S. Lender designated such
New Lending Office with respect to a Loan; PROVIDED, HOWEVER,
that this clause (ii) shall not apply to any Transferee or New
Lending Office that becomes a Transferee or New Lending Office as
a result of an assignment, participation, transfer or designation
made at the request of the Borrowers; and PROVIDED FURTHER,
HOWEVER, that this clause (ii) shall not apply to the extent the
indemnity payment or additional amounts any Transferee, or Lender
(or Transferee) through a New Lending Office, would be entitled
to receive (without regard to this clause (ii)) do not exceed the
indemnity payment or additional amounts that the person making
the assignment, participation or transfer to such Transferee, or
Lender (or Transferee) making the designation of such New Lending
Office, would have been entitled to receive in the absence of
such assignment, participation, transfer or designation.

(i) Any Lender (or Transferee) claiming any indemnity
payment or additional amounts payable pursuant to this Section
2.18 shall use reasonable efforts (consistent with legal and
regulatory restrictions) to file any certificate or document
reasonably requested in writing by the Borrowers or to change the
jurisdiction of its applicable lending office if the making of
such a filing or change would avoid the need for or reduce the
amount of any such indemnity payment or additional amounts that
may thereafter accrue and would not be otherwise disadvantageous
to such Lender (or Transferee) in its sole judgment.

(j) Nothing contained in this Section 2.18 shall require
any Lender (or Transferee) or Agent to make available any of its
tax returns (or any other information that it deems to be
confidential or proprietary).

(k) No Lender (or Transferee) shall be entitled to claim
any indemnity payment or additional amount payable pursuant to
this Section 2.18 with respect to any date unless such Lender
shall have notified the Borrowers that it will demand such
payment or additional amount not more than 90 days after the
later of (i) such date and (ii) the date on which such Lender (or
Transferee) becomes aware of such costs or reductions.

SECTION 2.19. ASSIGNMENT OF COMMITMENTS UNDER CERTAIN
CIRCUMSTANCES. In the event that (a) any Lender shall have
delivered a notice or certificate pursuant to Section 2.12 or
2.13, (b) the Borrowers shall be required to pay additional
amounts to any Lender under Section 2.18 or (c) a proposed
extension shall have been approved by the Consenting Lenders but
a Dissenting Lender shall have given or be deemed to have given
notice to the Agent of its objection thereto, the Borrowers shall
have the right, at their own expense, upon notice to such Lender
and the Agent, to require such Lender to transfer and assign
without recourse (in

accordance with and subject to the provisions set forth in Section 9.04)
all its interests, rights and obligations under this Amended Agreement to
another financial institution identified by the Borrowers and reasonably
acceptable to the Agent, and such financial institution shall assume such
obligations; PROVIDED that (i) no such assignment shall conflict with any
law, rule, regulation or order of any Governmental Authority and (ii) the
Borrowers shall pay or cause to be paid to the affected Lender in immediately
available funds on the date of such assignment 100% of the aggregate amount
of principal of and interest accrued to the date of payment on the Loans and
participations in the Letter of Credit Disbursements made by it hereunder
and all other amounts accrued for its account or owed to it hereunder;
PROVIDED FURTHER that, in the case of the circumstances or event referred
to in clauses (a) and (b) above, if prior to any such assignment the
circumstances or event that resulted in such Lender's notice or certificate
under Section 2.12 or 2.13 or demand for additional amounts under Section
2.18, as the case may be, shall cease to exist or become inapplicable
for any reason or if such Lender shall waive its rights in respect of such
circumstances or event under Section 2.12, 2.13 or 2.18, as the case may be,
then such Lender shall not thereafter be required to make any such assignment
hereunder.

SECTION 2.20. LETTERS OF CREDIT. (a) The Borrowers may
request the issuance of Letters of Credit, in a form reasonably
acceptable to the Agent and the Issuing Bank, for the account of
the Borrowers at any time and from time to time during the Letter
of Credit Availability Period; PROVIDED that any Letter of Credit
shall be issued only if, and each request by the Borrowers for
the issuance of any Letter of Credit shall be deemed a
representation and warranty of the Borrowers that, immediately
following the issuance of such Letter of Credit, (i) the Letter
of Credit Exposure shall not exceed $70,000,000 and (ii) the sum
of (A) the Letter of Credit Exposure and (B) the aggregate
principal amount of outstanding Loans shall not exceed the
aggregate amount of the Commitments at such time.

(b) Each Letter of Credit (other than any Sunwest Letter of
Credit) shall expire at the close of business on the earlier of
(i) 12 calendar months after the date of issuance of such Letter
of Credit and (ii) the last day of the Letter of Credit
Availability Period, unless such Letter of Credit expires by its
terms on an earlier date. Each Letter of Credit shall provide
for payments of drawings in dollars.

(c) Each issuance of any Letter of Credit shall be made on
at least three Business Days' prior irrevocable written or
telecopy notice (or such shorter notice as shall be acceptable to
the Issuing Bank) from the Borrowers to the Agent and the Issuing
Bank specifying the date of issuance, the date on which such
Letter of Credit is to expire in accordance with Section 2.20(b),
the amount of such Letter of Credit, the name and address of the
beneficiary of such Letter of Credit, and such other information
as may be necessary or desirable to complete such Letter of
Credit. The Issuing Bank will give the Agent prompt notice of
the issuance and amount of such Letter of Credit and the
expiration date of such Letter of Credit (and the Agent shall
give prompt notice thereof to each Lender). During the Letter of
Credit Availability Period, the Issuing Bank also will give the
Agent (and, in the case of clause (ii) below, the Lenders) (i)
daily notice of the amount available to be drawn under each
outstanding Letter of Credit and (ii) a quarterly summary
indicating, on a daily basis during such quarter, the

issuance of any Letter of Credit and the amount thereof, the expiration of
any Letter of Credit and the amount thereof and the payment on any draft
presented under any Letter of Credit.

(d) By the issuance of a Letter of Credit (including an
Outstanding Letter of Credit) and without any further action on
the part of the Issuing Bank, the Agent or the Lenders in respect
thereof, the Issuing Bank hereby grants to each Lender, and each
Lender hereby acquires from the Issuing Bank, a participation in
such Letter of Credit equal to such Lender's pro rata portion, as
determined under Section 2.15, of the aggregate amount available
to be drawn under such Letter of Credit, effective upon the
issuance of such Letter of Credit. In consideration and in
furtherance of the foregoing, each Lender hereby absolutely and
unconditionally agrees to pay to the Agent, on behalf of the
Issuing Bank, in accordance with Section 2.03(d), such Lender's
pro rata portion, as determined under Section 2.15, of each
Letter of Credit Disbursement made by the Issuing Bank and not
reimbursed by the Borrowers when due in accordance with Section
2.20(g); PROVIDED that the Lenders shall not be obligated to make
any such payment with respect to any wrongful Letter of Credit
Disbursement made as a result of the gross negligence or willful
misconduct of the Issuing Bank.

(e) Each Lender acknowledges and agrees that its obligation
to acquire participations pursuant to Section 2.20(d) in respect
of Letters of Credit (including Outstanding Letters of Credit) is
absolute and unconditional and shall not be affected by any
circumstance whatsoever, including the occurrence and continuance
of a Default or Event of Default, and that each such payment
shall be made without any offset, abatement, withholding or
reduction whatsoever (subject only to the proviso set forth in
Section 2.20(d)).

(f) During the Letter of Credit Availability Period, the
Borrowers shall pay to the Agent, on the last day of March, June,
September and December in each year and on the date on which the
Commitments shall be terminated as provided herein, (i) for the
account of the Lenders, ratably in proportion to their
Commitments, a fee on the average daily aggregate amount
available to be drawn under all outstanding Letters of Credit
(including Outstanding Letters of Credit) during the preceding
quarter (or shorter period commencing with the Effective Date) at
a rate per annum equal to the Eurodollar Margin from time to time
in effect during such period pursuant to Section 2.07 and (ii)
for the account of the Issuing Bank, a fee on the average daily
aggregate amount available to be drawn under all outstanding
Letters of Credit (including Outstanding Letters of Credit) of
such Issuing Bank during the preceding quarter (or shorter period
commencing with the Effective Date) at a rate per annum equal to
0.125%. Such fees shall be computed on the basis of the actual
number of days elapsed in a year of 360 days. Such fees shall
accrue from and including the Effective Date to but excluding the
last day of the Letter of Credit Availability Period. In
addition to the foregoing, the Borrowers shall pay directly to
the Issuing Bank, for its account, payable within 15 days after
demand therefor by the Issuing Bank, the Issuing Bank's customary
processing and documentation fees in connection with the issuance
or amendment of or payment on any Letter of Credit, including any
trade or documentary Letter of Credit.

(g) If the Issuing Bank shall pay any draft presented under
a Letter of Credit (including an Outstanding Letter of Credit),
the Borrowers shall pay to the Agent, on behalf of

the Issuing Bank, an amount equal to the amount of such draft before
12:00 noon, Dallas time, on the day on which the Issuing Bank shall
have notified the Borrowers that payment of such draft will be
made. The Agent shall promptly pay any such amounts received by
it to the Issuing Bank. If the Borrowers shall fail to pay any
amount required to be paid under this Section 2.20(g) when due,
such unpaid amount shall bear interest, for each day from and
including the due date to but excluding the date of payment, at a
rate per annum equal to the rate applicable to ABR Revolving
Loans during such period pursuant to Section 2.07, plus 2.00%,
but in no event to exceed the Highest Lawful Rate.

(h) To the fullest extent permitted under applicable law,
the Borrowers' obligations to reimburse Letter of Credit
Disbursements as provided in Section 2.20(g) shall be absolute,
unconditional and irrevocable and shall be performed strictly in
accordance with the terms of this Amended Agreement under any and
all circumstances whatsoever, and irrespective of:

(i) any lack of validity or enforceability of any
Letter of Credit (including any Outstanding Letter of
Credit) or any other Loan Document;

(ii) the existence of any claim, setoff, defense or
other right which Horizon, Continental, any Subsidiary or
any other person may at any time have against the
beneficiary under any Letter of Credit (including any
Outstanding Letter of Credit), the Issuing Bank, the Agent,
any Lender or any other person in connection with this
Amended Agreement, any other Loan Document or any other
related or unrelated agreement or transaction;

(iii) any draft or other document presented under a
Letter of Credit (including an Outstanding Letter of Credit)
proving to be forged, fraudulent, invalid or insufficient in
any respect or failing to comply with the Uniform Customs
and Practices for Documentary Credits, as in effect from
time to time, or any statement therein being untrue or
inaccurate in any respect, except to the extent the same is
attributable to the gross negligence or willful misconduct
of the Issuing Bank;

(iv) payment by the Issuing Bank under a Letter of
Credit (including an Outstanding Letter of Credit) against
presentation of a draft or other document which does not
comply with the terms of such Letter of Credit; PROVIDED
that such payment was not wrongfully made as a result of the
gross negligence or willful misconduct of the Issuing Bank;
and

(v) any other act or omission or delay of any kind or
any other circumstance or event whatsoever, whether or not
similar to any of the foregoing and whether or not
foreseeable, that might, but for the provisions of this
Section 2.20(h), constitute a legal or equitable discharge
of the Borrowers' obligations hereunder, except to the
extent the same is attributable to the gross negligence or
willful misconduct of the Issuing Bank.

(i) To the fullest extent permitted under applicable law,
it is expressly understood and agreed that, for purposes of
determining whether a wrongful payment under a Letter of Credit

(including an Outstanding Letter of Credit) resulted from the
Issuing Bank's gross negligence or willful misconduct, (i) the
Issuing Bank's acceptance of documents that appear on their face
to be in order, without responsibility for further investigation,
regardless of any notice or information to the contrary, (ii) the
Issuing Bank's exclusive reliance on the documents presented to
it under such Letter of Credit as to any and all matters set
forth therein, including the amount of any draft presented under
such Letter of Credit, whether or not the amount due to the
beneficiary thereunder equals the amount of such draft and
whether or not any document presented pursuant to such Letter of
Credit proves to be insufficient in any respect (so long as such
document on its face appears to be in order), and whether or not
any other statement or any other document presented pursuant to
such Letter of Credit proves to be forged or invalid or any
statement therein proves to be inaccurate or untrue in any
respect whatsoever and (iii) any noncompliance in any immaterial
respect of the documents presented under such Letter of Credit
with the terms thereof shall, in each case, be deemed not to
constitute willful misconduct or gross negligence of the Issuing
Bank. It is further understood and agreed that, notwithstanding
the proviso to clause (iv) of Section 2.20(h), the Borrowers'
obligations hereunder to reimburse Letter of Credit Disbursements
will not be excused by the gross negligence or willful misconduct
of the Issuing Bank to the extent that such Letter of Credit
Disbursement actually discharged a liability of, or otherwise
benefited, or was recovered by, either Borrower; PROVIDED that
the foregoing shall not be construed to excuse the Issuing Bank
from liability to the Borrowers to the extent of any direct
damages suffered by the Borrowers that are caused by the Issuing
Bank's gross negligence or willful misconduct in determining
whether drafts and other documents presented under a Letter of
Credit comply with the terms thereof.

(j) The Issuing Bank shall, promptly following its receipt
thereof, examine all documents purporting to represent a demand
for payment under a Letter of Credit. The Issuing Bank shall as
promptly as possible give telephonic notification, confirmed by
telex or telecopy, to the Agent and the Borrowers of such demand
for payment and whether the Issuing Bank has made or will make a
Letter of Credit Disbursement thereunder; PROVIDED that the
failure to give such notice shall not relieve the Borrowers of
their obligation to reimburse any such Letter of Credit
Disbursement in accordance with this Section 2.20. The Agent
shall promptly give each Lender notice thereof.

(k) In the event that the Borrowers are required pursuant
to the terms of this Amended Agreement or any other Loan Document
to provide cash collateral in respect of the Letter of Credit
Exposure, the Borrowers shall deposit in an account with the
Agent, for the benefit of the Lenders, an amount in cash equal to
the Letter of Credit Exposure (or such lesser amount as shall be
required hereunder or thereunder). Such deposit shall be held by
the Agent as collateral for the payment and performance of the
Obligations. The Agent shall have exclusive dominion and
control, including the exclusive right of withdrawal, over such
account. Other than any interest earned on the investment of
such deposits in Cash Equivalents, which investments shall be
made as directed by the Borrowers (unless such investments shall
be contrary to applicable law or regulation or a Default or Event
of Default shall have occurred and be continuing, in which case
the determination of whomever to make investments shall be made
at the option and in the discretion of the Agent), such deposits
shall not bear interest.

Interest or profits, if any, on such investments shall accumulate
in such account. Moneys in such account shall automatically be applied
by the Agent to reimburse the Issuing Bank for Letter of Credit
Disbursements and, if the maturity of the Loans has been accelerated,
to satisfy the Obligations. If the Borrowers are required to provide
an amount of cash collateral hereunder as a result of an Event of Default,
such amount (to the extent not applied as aforesaid) shall be returned to
the Borrowers within three Business Days after all Events of Default have
been cured or waived. If the Borrowers are required to provide an amount
of cash collateral hereunder pursuant to Section 2.11(b), such amount
(to the extent not applied as aforesaid) shall be returned to the Borrowers
upon demand; PROVIDED that, after giving effect to such return, (i) the sum
of (A) the aggregate amount of the Letter of Credit Exposure plus (B) the
aggregate outstanding principal amount of Loans would not exceed the aggregate
Commitments and (ii) no Default or Event of Default shall have occurred and be
continuing.

(l) "OUTSTANDING LETTERS OF CREDIT" shall mean the Horizon
Letters of Credit, the Continental Letters of Credit and the
Sunwest Letters of Credit, all as listed on Schedule 2.20(l).
The parties hereto agree that each Outstanding Letter of Credit
will be treated as if it had been originally issued under this
Amended Agreement. Specifically, and without limitation of the
foregoing or the other provisions of this Section 2.20, (i) the
amount of each Outstanding Letter of Credit shall count towards
the limits set forth in the proviso to Section 2.20(a) and in
Section 2.02, (ii) each Lender hereby absolutely and
unconditionally agrees to pay to the Agent, on behalf of the
Issuing Bank, in accordance with Section 2.03(d), such Lender's
pro rata portion, as determined under Section 2.15, of each
Letter of Credit Disbursement made with respect to any of the
Outstanding Letters of Credit (subject to the proviso set forth
in Section 2.20(d)) and (iii) the Issuing Bank of any of the
Outstanding Letters of Credit shall have the benefit of all
agreements, covenants and indemnities of the Issuing Bank set
forth under this Amended Agreement and shall comply with all
agreements and obligations set forth herein which bind the
"Issuing Bank", insofar as such term is used in relation to the
Outstanding Letters of Credit.

organization, (b) has all requisite power and authority to own
its property and assets and to carry on its business as now

obligations under each of the Loan Documents and each other
agreement or instrument contemplated

thereby to which it is or will be a party and, in the case of Horizon,

obtain extensions of credit hereunder.

SECTION 3.02. AUTHORIZATION. The execution, delivery and
performance by each of Horizon and the Subsidiaries of each of

thereunder), or of the articles of incorporation, certificate of
partnership, by-laws, partnership agreement or other constitutive
documents of Horizon or any Subsidiary, (B) any order of any
Governmental Authority or (C) any provision of any indenture or

SECTION 3.03. ENFORCEABILITY. This Amended Agreement has
been duly executed and delivered by each Borrower and
constitutes, and each other Loan Document when executed and
delivered by Horizon or any Subsidiary will constitute, a legal,
valid and binding obligation of such party enforceable against
such party in accordance with its terms, except as such
enforceability may be limited by bankruptcy, insolvency,
reorganization, moratorium or similar laws affecting the
enforceability of creditors' rights generally and by equitable
principles of general applicability (regardless of whether such
enforceability is considered in a proceeding in equity or at
law).

SECTION 3.04. CONSENTS AND GOVERNMENTAL APPROVALS. No
action, consent or approval of, registration or filing with or
any other action by (a) any Governmental Authority (including the
SEC), (b) any stockholder or creditor of Horizon or any
Subsidiary or (c) any other person is or will be required in
connection with the Tender Offers, the Facility or the
performance by Horizon or any Subsidiary of the Loan Documents to
which it is or will be a party, except such as (i) have been made
or obtained and are in full force and effect or (ii) are required
to waive the conflicts, if any, set forth on Schedule 3.02.

SECTION 3.05. FINANCIAL STATEMENTS. Horizon has heretofore
furnished to the Lenders (a)(i) the consolidated balance sheet,
statement of operations and statement of cash flows of Horizon
and its Consolidated Subsidiaries as of and for the fiscal year
ended May 31, 1995, audited by and accompanied by the opinion of
▇▇▇▇▇▇ ▇▇▇▇▇▇▇▇ LLP, independent public accountants, and (ii) the
consolidated balance sheet, statement of operations and statement

balance sheet, statement of operations and statement of cash flows of
Horizon and its Consolidated Subsidiaries as of July 31, 1995,
certified by a financial officer of Horizon (the financial
statements referred to in clauses (a) and (b) above,
collectively, the "FINANCIAL STATEMENTS"). The Financial
Statements present fairly in accordance with GAAP (subject, in
the case of the unaudited Financial Statements, to normal,
recurring year end audit adjustments) the consolidated financial
position and the consolidated results of operations and
consolidated cash flows of the Borrowers and their Consolidated
Subsidiaries as of such dates and for such periods. Such balance
sheets and the notes thereto disclose all material liabilities,
actual or contingent, of the Borrowers and their Consolidated
Subsidiaries as of the dates thereof. The Financial Statements
were prepared in accordance with GAAP applied on a consistent
basis during the periods involved (except as may be indicated in
the notes thereto or, in the case of the unaudited Financial
Statements, as permitted by Form 10-Q of the SEC).

SECTION 3.06. NO MATERIAL ADVERSE CHANGE. Since May 31,
1995, except for any such changes expressly disclosed in any
filing with the SEC made after May 31, 1995 and prior to the date
hereof, there has occurred no Material Adverse Change and there
exists no condition, event or occurrence that, individually or in
the aggregate, could reasonably be expected to result in a
Material Adverse Change.

SECTION 3.07. TITLE TO PROPERTIES; POSSESSION UNDER LEASES.
(a) Each of Horizon and the Subsidiaries has good and marketable
title to, or valid leasehold interests in, all its material
properties and assets, except for minor defects in title that do
not interfere with its ability to conduct its business as
currently conducted or to utilize such properties and assets for
their intended purposes. All such properties and assets are free
and clear of Liens, other than Liens permitted by Section 6.02.

(b) Schedule 3.07 sets forth, as of the Effective Date, a
true, complete and correct list of (i) all real property owned by
Horizon and the Subsidiaries having a book value in excess of
$100,000; (ii) all material real property leased by Horizon and
the Subsidiaries; and (iii) the location of each such real
property.

(c) Each of Horizon and the Subsidiaries has complied with
all obligations under all material leases to which it is a party
and all such leases are in full force and effect. Each of
Horizon and the Subsidiaries enjoys peaceful and undisturbed
possession under all such material leases.

SECTION 3.08. SUBSIDIARIES. Schedule 3.08 sets forth as of
the Effective Date a list of all the Subsidiaries, the respective
jurisdictions of organization thereof and the percentage
ownership interest, direct or indirect, of Horizon therein and
specifies which of such Subsidiaries are Material Subsidiaries
and which of such Subsidiaries are Inactive Subsidiaries.

SECTION 3.09. LITIGATION; COMPLIANCE WITH LAWS. (a) There
are no actions, suits or proceedings at law or in equity or by or
before any Governmental Authority now pending or, to the
knowledge of the Borrowers, threatened against or affecting
Horizon, any Subsidiary or

any business, property or rights of Horizon or any Subsidiary (i) which
involve any Loan Document or the Tender Offers or (ii) as to which there is a
reasonable possibility of an adverse determination and which, if adversely
determined, could be reasonably expected to result, individually or in the
aggregate, in a Material Adverse Effect.

(b) Neither Horizon nor any Subsidiary is in violation of any law, rule
or regulation, or in default with respect to any judgment, writ, injunction,
order or decree, of any Governmental Authority, where such violation or
default could be reasonably expected to result, individually or in the
aggregate, in a Material Adverse Effect. Except as set forth in Schedule
3.09, neither Horizon nor any Subsidiary has received any written
communication during the past three years from any Governmental Authority
that alleges that such party or any of its Affiliates is not in compliance in
any material respect with any law, rule or regulation or any judgment, writ,
injunction or decree. Continental and its subsidiaries have in all material
respects been reimbursed by their fiscal intermediaries for only the correct
amounts for therapeutic recreation services as routine services rather than
ancillary services, and have not in any material respect sought payment from,
nor been paid by, Medicare, for therapeutic recreation services, on a charge
basis.

SECTION 3.10. AGREEMENTS. (a) Each "material contract" (within the
meaning of Item 601(b)(10) of Regulation S-K under the Exchange Act), each
material agreement relating to the incurrence of Indebtedness or Disqualified
Equity Interests and each material Operating Lease to which Horizon or any
Subsidiary is a party or by which it or any of its properties or assets are
or may be bound as of the date hereof is listed on Schedule 3.10 hereto
(collectively, the "MATERIAL CONTRACTS"). Except as expressly set forth in
Schedule 3.10, none of the Material Contracts have been amended, modified or
waived in any respect.

(b) Except as set forth in Schedule 3.10, each Material Contract is
valid, binding and in full force and effect and is enforceable by Horizon or
the Subsidiary which is a party thereto in accordance with its terms, except
as such enforceability may be limited by bankruptcy, insolvency,
reorganization, moratorium or similar laws affecting the enforceability of
creditors' rights generally and by equitable principles of general
applicability (regardless of whether such enforceability is considered in a
proceeding in equity or at law). Except as set forth in Schedule 3.10, each
of Horizon and the Subsidiaries has performed in all material respects all
obligations required to be performed by it to date under the Material
Contracts and it is not (with or without the lapse of time or the giving of
notice, or both) in breach or default in any material respect thereunder and,
to the knowledge of the Borrowers, no other party to any of the Material
Contracts is (with or without the lapse of time or the giving of notice, or
both) in breach or default in any material respect thereunder. Neither
Horizon nor any Subsidiary, nor, to the knowledge of the Borrowers, any other
party to any Material Contract, has given notice of termination of, or taken
any action inconsistent with the continuation of, any Material Contract. None
of such other parties has any presently exercisable right to terminate any
Material Contract nor will any such other party have any right to terminate
any Material Contract on account of the execution, delivery or performance of
the Loan Documents or the consummation of the Tender Offers.

(c) The Obligations of Continental for money borrowed by Continental
constitute "Senior Indebtedness" within the meaning of the Subordinated Note
Indentures. As of the Effective Date, there is no outstanding "Designated
Senior Indebtedness" within the meaning of the Subordinated Note Indentures,
except for the Facility. As of the Effective Date, no "Default" or "Event of
Default" within the meaning of the Subordinated Note Indentures has occurred
and is continuing.

SECTION 3.11. FEDERAL RESERVE REGULATIONS. (a) Neither Horizon nor
any Subsidiary is engaged principally, or as one of its important activities,
in the business of extending credit for the purpose of purchasing or carrying
Margin Stock.

(b) No part of the proceeds of any Loan and no Letter of Credit will be
used, whether directly or indirectly, and whether immediately, incidentally
or ultimately, for any purpose which entails a violation of, or which is
inconsistent with, the provisions of the regulations of the Board, including
Regulations G, U and X.

SECTION 3.12. INVESTMENT COMPANY ACT; PUBLIC UTILITY HOLDING COMPANY
ACT. Neither Horizon nor any Subsidiary is (a) an "investment company" as
defined in, or subject to regulation under, the Investment Company Act of
1940 or (b) a "holding company" as defined in, or subject to regulation
under, the Public Utility Holding Company Act of 1935 or (c) subject to
regulation as a "public utility" or a "public service corporation" or the
equivalent under any federal or state law.

SECTION 3.13. USE OF PROCEEDS. The proceeds of the Loans will be used
solely for the general corporate purposes of Horizon and the Subsidiaries,
including repurchasing the Subordinated Notes and the Greenery Convertible
Notes to the extent permitted in accordance with the terms hereof and
providing funds for working capital, capital expenditures in the ordinary
course of business and acquisitions permitted hereunder. The Letters of
Credit will be issued solely to support various financial and other
performance obligations of Horizon and the Subsidiaries incurred in the
ordinary course of business. The proceeds of Subsidiary Intercompany
Indebtedness of any Subsidiary will be used by such Subsidiary solely for the
general corporate purposes of such Subsidiary, including providing funds for
working capital, capital expenditures in the ordinary course of business and
acquisitions permitted hereunder.

SECTION 3.14. TAX RETURNS. Each of Horizon and the Subsidiaries has
filed or caused to be filed all Federal, state and local tax returns required
to have been filed by it and has paid or caused to be paid all taxes shown to
be due and payable on such returns or on any assessments received by it,
except taxes that are being contested in good faith by appropriate
proceedings and for which adequate reserves in accordance with GAAP have been
set aside on the Financial Statements.

SECTION 3.15. NO MATERIAL MISSTATEMENTS. (a) No information, report,
financial statement, exhibit or schedule furnished by or on behalf of Horizon
or any Subsidiary to the Agent or any Lender in connection with the
negotiation of any Loan Document or included therein or delivered pursuant
thereto contained, contains or will contain any material

misstatement of fact or omitted, omits or will omit to state any material
fact necessary to make the statements therein, in the light of the
circumstances under which they were, are or will be made, not misleading.

(b) The Borrowers have timely and duly filed all the reports and other
material that they were required to file with the SEC since May 31, 1995.
Copies of all such reports and other material, together in each case with all
amendments thereto (collectively, the "DISCLOSURE DOCUMENTS"), have been
delivered to the Agent. Except as reflected in any subsequent amendment or
supplement to a Disclosure Document, no Disclosure Document, including any
financial statement contained therein, at the time it was filed or mailed to
stockholders, as the case may be, contained any misstatement of a material
fact or omitted to state a material fact necessary to make the statements
contained therein, in the light of the circumstances under which they were
made, not misleading.

(c) All representations and warranties of the Borrowers set forth in
the Original Credit Agreement were true and correct in all material respects
on and as of the Closing Date, except to the extent such representations and
warranties expressly relate to an earlier date (in which case such
representations and warranties were true and correct in all material respects
on and as of such earlier date). Immediately prior to the effectiveness of
this Amended Agreement, no Default or Event of Default has occurred and is
continuing under the Original Credit Agreement.

SECTION 3.16. EMPLOYEE BENEFIT PLANS. (a) Each of Horizon and the
Commonly Controlled Entities is in compliance in all material respects with
the applicable provisions of ERISA and the regulations and published
interpretations thereunder. Neither a Reportable Event nor an "accumulated
funding deficiency" (within the meaning of Section 412 of the Code or Section
302 of ERISA) has occurred within the last five years with respect to any
Plan, and each Plan has complied in all material respects with the applicable
provisions of ERISA and the Code. Neither Horizon nor any Commonly
Controlled Entity has any unsatisfied liability with respect to a Single
Employer Plan that has been terminated and no Lien in favor of the PBGC or a
Plan has arisen during the last five years.

(b) Except as set forth on Schedule 3.16, the present value of all
accrued benefits under each Single Employer Plan in which Horizon or any
Commonly Controlled Entity is a participant (based on those assumptions used
to fund the Plans) did not, as of the last day of the plan year that ended
prior to the date of this Amended Agreement, exceed the value of the assets
of such Plan allocable to such accrued benefits.

(c) Neither Horizon nor any Commonly Controlled Entity has had a
complete or partial withdrawal from any Multiemployer Plan, and neither
Horizon nor any Commonly Controlled Entity would become subject to any
liability under ERISA if Horizon or such Commonly Controlled Entity were to
withdraw completely from all Multiemployer Plans as of the last day of the
plan year that ended prior to the date of this Amended Agreement.

(d) No such Multiemployer Plan with respect to which Horizon or any
Commonly Controlled Entity could incur potential liability in excess of
$250,000 is in "reorganization" or "insolvent," within the meaning of such
terms as used in ERISA.

(e) The present value (determined using actuarial and other assumptions
which are reasonable in respect of the benefits provided and the employees
participating) of the liability of Horizon and each Subsidiary for post
retirement benefits to be provided to their current and former employees
under Plans which are welfare benefit plans (as defined in Section 3(1) of
ERISA) does not, in the aggregate, exceed the assets under all such Plans
allocable to such benefits, except as set forth in Schedule 3.16.

SECTION 3.17. ENVIRONMENTAL AND SAFETY MATTERS. Except as set forth in
Schedule 3.17, each of Horizon and the Subsidiaries has complied in all
material respects with all applicable Federal, state, local and other
statutes, ordinances, orders, judgments, rulings and regulations relating to
protection of the environment or to employee health or safety. Except as set
forth in Schedule 3.17, neither Horizon nor any Subsidiary has received
notice of any material failure so to comply. The facilities of Horizon and
the Subsidiaries do not manage or contain any hazardous wastes, hazardous
substances, hazardous materials, toxic substances, toxic pollutants or
similarly denominated substances, as those terms or similar terms are used in
the Resource Conservation and Recovery Act, the Comprehensive Environmental
Response Compensation and Liability Act, the Hazardous Materials
Transportation Act, the Toxic Substance Control Act, the Clean Air Act, the
Clean Water Act or any other applicable law relating to protection of the
environment or to employee health and safety (collectively, "HAZARDOUS
MATERIALS"), in violation in any material respect of any such law or any
regulations promulgated pursuant thereto. Except as set forth in Schedule
3.17, to the knowledge of the Borrowers, there are no events, conditions or
circumstances involving environmental pollution, regulation or control or
employee health or safety that are reasonably likely to result in any
material liabilities being incurred by Horizon or any Subsidiary.

SECTION 3.18. SECURITY INTERESTS. The Agent for the benefit of the
Secured Parties will at all times have the Liens provided for in the Pledge
Agreements and the Pledge Agreements will at all times constitute a valid and
continuing lien of record and first priority perfected security interest in
all the Collateral.

SECTION 3.19. SOLVENCY. On and as of the Effective Date, each of
Horizon and the Subsidiaries will be Solvent. "Solvent" means, with respect
to any person, that (a) the sum of the assets of such person, both at a fair
valuation and at present fair salable value, will exceed the liabilities of
such person, (b) such person will have sufficient capital with which to
conduct its business as presently conducted and as proposed to be conducted
and (c) such person has not incurred debts, and does not intend to incur
debts, beyond its ability to pay such debts as they mature. For purposes of
the foregoing definition, "DEBTS" means any liabilities on claims, and
"CLAIM" means (i) a right to payment, whether or not such right is reduced to
judgment, liquidated, unliquidated, fixed, contingent, matured, unmatured,
disputed, undisputed, legal, equitable, secured or unsecured, or (ii) a right
to an equitable remedy for breach of performance if such breach gives rise to
a payment, whether or not such right to an equitable

remedy is reduced to judgment, fixed, contingent, matured, unmatured,
disputed, undisputed, secured or unsecured. With respect to any contingent
or disputed liabilities, such liabilities shall be computed at the amount
which, in light of all the facts and circumstances existing at the time,
represents the amount which can reasonably be expected to become an actual or
matured liability.

SECTION 3.20. TRANSACTIONS WITH AFFILIATES. Except as set forth in
Schedule 3.20 and except for agreements and arrangements among Horizon and
the Subsidiaries or among the Subsidiaries, as of the Effective Date, neither
Horizon nor any of the Subsidiaries is a party to or engaged in any
transaction with, and none of the properties and assets of Horizon or any of
the Subsidiaries is subject to or bound by, any agreement or arrangement
with, any Affiliate of Horizon or any of the Subsidiaries.

SECTION 3.21. INSURANCE. Each of Horizon and the Subsidiaries
maintains policies of fire and casualty, liability, malpractice, business
interruption and other forms of insurance in such amounts, with such
deductibles and against such risks and losses as are reasonable for the
business and assets of Horizon and the Subsidiaries. All such policies are

ARTICLE VIII

THE AGENT AND ISSUING BANK

SECTION 8.01. APPOINTMENT AND AUTHORIZATION. (a) Each of the Lenders,
and each subsequent holder of any Note by its acceptance thereof, hereby
irrevocably appoints and authorizes the Agent and the Issuing Bank to take
such actions as agent on behalf of such Lender or holder and to exercise such
powers as are specifically delegated to the Agent or the Issuing Bank, as the
case may be, by the terms and provisions hereof and of the other Loan
Documents, together with such actions and powers as are reasonably incidental
thereto.

(b) The Agent is hereby expressly authorized by the Lenders, without
hereby limiting any implied authority, and hereby agrees (in the case of
clause (ii) below, at the direction of the Required Lenders), (i) to receive
on behalf of the Lenders all payments of principal of and interest on the
Loans and all other amounts due to the Lenders hereunder, and promptly to
distribute to each Lender its pro rata portion, as determined under Section
2.15, of each payment so received; (ii) to give notice on behalf of each of
the Lenders to the Borrowers of any Event of Default specified in this
Amended Agreement of which the Agent has actual knowledge acquired in
connection with its agency hereunder; and (iii) to distribute to each Lender
copies of all notices, financial statements and other materials delivered by
the Borrowers (including all amendments, waivers and consents entered into)
pursuant to this Amended Agreement as received by the Agent.

SECTION 8.02. LIABILITY OF AGENT. Neither the Agent, the Issuing Bank,
nor any of their respective directors, officers, employees or agents, shall
be liable as such for any action taken or omitted to be taken by any of them,
except for such party's own gross negligence or willful misconduct, or be
responsible for any statement, warranty or representation herein or the
contents of any document delivered in connection herewith, or be required to
ascertain or to make any inquiry concerning the performance or observance by
Horizon or any Subsidiary

of any of the terms, conditions, covenants or agreements contained in any
Loan Document. Neither the Agent nor the Issuing Bank shall be responsible
to the Lenders or the holders of the Notes for the due execution,
genuineness, validity, enforceability or effectiveness of this Amended
Agreement, the Notes or any other Loan Documents or other instruments or
agreements. Each of the Agent and the Issuing Bank may deem and treat the
payee of any Note as the owner thereof for all purposes hereof until it shall
have received from the payee of such Note notice, given as provided herein,
of the transfer thereof in compliance with Section 9.04. Each of the Agent
and the Issuing Bank shall in all cases be fully protected in acting, or
refraining from acting, in accordance with written instructions signed by the
Required Lenders and, except as otherwise specifically provided herein, such
instructions and any action or inaction pursuant thereto shall be binding on
all the Lenders and each subsequent holder of any Note. Each of the Agent
and the Required Lenders shall, in the absence of knowledge to the contrary,
be entitled to rely on any instrument or document believed by it in good
faith to be genuine and correct and to have been signed or sent by the proper
person or persons. To the fullest extent permitted under applicable law,
neither the Agent, the Issuing Bank nor any of their respective directors,
officers, employees or agents, shall have any responsibility to either
Borrower on account of the failure of or delay in performance or breach by
any Lender of any of its obligations hereunder or to any Lender on account of
the failure of or delay in performance or breach by any other Lender or
Horizon or any Subsidiary of any of their respective obligations hereunder or
under any other Loan Document or in connection herewith or therewith. Each
of the Agent and the Issuing Bank may execute any and all duties hereunder by
or through agents or employees, shall be entitled to consult with legal
counsel, independent public accountants and other experts selected by it with
respect to all matters arising hereunder and, to the fullest extent permitted
under applicable law, shall not be liable for any action taken or omitted to
be taken in good faith by it in accordance with the advice of such counsel,
accountants or experts.

SECTION 8.03. ACTION BY AGENT. The Lenders hereby acknowledge that
neither the Agent nor the Issuing Bank shall be under any duty to take any
discretionary action permitted to be taken by it pursuant to the provisions
of this Amended Agreement unless it shall be requested in writing to do so by
the Required Lenders. The obligations of the Agent and the Issuing Bank
under the Loan Documents are only those expressly set forth herein and
therein. Without limiting the generality of the foregoing, the Agent shall
not be required to take any action with respect to any Default or Event of
Default, except as expressly provided in Article VII.

SECTION 8.04. SUCCESSOR AGENTS. Subject to the appointment and
acceptance of a successor as provided below, each of the Agent and the
Issuing Bank (except, in the case of the Issuing Bank, in respect of Letters
of Credit issued by it) may resign at any time by notifying the Lenders and
the Borrowers. Upon any such resignation, the Required Lenders shall have
the right, subject (so long as no Event of Default shall have occurred and be
continuing) to the prior written consent of the Borrowers, to appoint a
successor. If a successor shall not have been so appointed by the Required
Lenders, or shall not have accepted such appointment, within 30 days after
the retiring Agent or Issuing Bank, as the case may be, gives notice of its
resignation, then the retiring Agent or Issuing Bank, as the case

may be, may, on behalf of the Lenders, appoint a successor, which shall be a
commercial bank organized or licensed under the laws of the United States of
America or of any State thereof and having a combined capital and surplus of
at least $500,000,000 or an Affiliate of any such bank. Upon the acceptance
of any appointment as the Agent or Issuing Bank, as the case may be,
hereunder by a successor bank, such successor shall succeed to and become
vested with all the rights, powers, privileges and duties of the retiring
Agent or Issuing Bank and the retiring Agent or Issuing Bank shall be
discharged from its duties and obligations hereunder. After the resignation
of the Agent or Issuing Bank, as the case may be, hereunder, the provisions
of this Article and Section 9.05 shall continue in effect for its benefit in
respect of any actions taken or omitted to be taken by it while it was acting
as the Agent or Issuing Bank.

SECTION 8.05. AGENT AND AFFILIATE. With respect to the Loans made by
it hereunder, the Letters of Credit issued by it hereunder and the Notes
issued to it, each of the Agent and the Issuing Bank in its individual
capacity and not as the Agent or Issuing Bank shall have the same rights and
powers as any other Lender and may exercise the same as though it were not
the Agent or Issuing Bank. Each of the Agent and the Issuing Bank (and its
Affiliates) may accept deposits from, lend money to and generally engage in
any kind of business and transactions with Horizon or any Subsidiary or other
Affiliate thereof as if it were not the Agent or Issuing Bank (or such
Affiliate thereof).

SECTION 8.06. INDEMNIFICATION. Each Lender agrees (a) to reimburse
each of the Agent and the Issuing Bank, on demand, in the amount of its pro
rata share (based on its Commitment hereunder) of any expenses incurred for
the benefit of the Lenders by the Agent or the Issuing Bank, as the case may
be, including counsel fees and compensation of agents and employees paid for
services rendered on behalf of the Lenders, which shall not have been
reimbursed by Horizon or any Subsidiary, and (b) to indemnify and hold
harmless each of the Agent, the Issuing Bank and any of their respective
directors, officers, employees or agents, on demand, in the amount of such
pro rata share, from and against any and all liabilities, taxes, obligations,
losses, damages, penalties, actions, judgments, suits, costs, expenses or
disbursements of any kind or nature whatsoever which may be imposed on,
incurred by or asserted against it in its capacity as the Agent or the
Issuing Bank or any of them in any way relating to or arising out of this
Amended Agreement or any other Loan Document or any action taken or omitted
by it or any of them under this Amended Agreement or any other Loan Document,
to the extent the same shall not have been reimbursed by Horizon or any
Subsidiary; PROVIDED that no Lender shall be liable for any portion of such
liabilities, obligations, losses, damages, penalties, actions, judgments,
suits, costs, expenses or disbursements resulting from the gross negligence
or willful misconduct of the Agent, the Issuing Bank or any of their
respective directors, officers, employees or agents.

SECTION 8.07. CREDIT DECISION. Each Lender acknowledges that it has,
independently and without reliance upon the Agent, the Issuing Bank or any
other Lender and based on such documents and information as it has deemed
appropriate, made its own credit analysis and decision to enter into this
Amended Agreement. Each Lender also acknowledges that it will, independently
and without reliance upon the Agent, the Issuing Bank or any other Lender and
based on such documents and information as it shall from time to time deem

appropriate, continue to make its own decisions in taking or not taking
action under or based upon this Amended Agreement or any other Loan Document,
any related agreement or any document furnished hereunder or thereunder.

the parties to each such assignment shall execute and deliver to the Agent an
Assignment and Acceptance, together with the Note or Notes subject to such

assignee, if it shall not be a Lender or an Affiliate thereof, shall deliver

obligations under this Amended Agreement, any other Loan Document or any
other instrument or document furnished pursuant hereto; (iii) such assignee
represents and warrants that it is legally authorized to enter into such
Assignment and Acceptance; (iv) such assignee confirms that it has received a
copy of the Loan Documents, together with copies of the most recent Required
Financial Statements and such other documents and information as it has

Agreement are required to be performed by it as a Lender.

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 in the absence of manifest error, and the Borrowers, 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 Amended Agreement. The Register shall be available for inspection by
the Borrowers, the Issuing Bank and any Lender, at any reasonable time and
from time to time upon reasonable prior notice.

(e) Upon its receipt of a duly completed Assignment and Acceptance
executed by an assigning Lender and an assignee together with the Note or
Notes subject to such assignment, an Administrative Questionnaire completed
in respect of the assignee (unless the assignee shall already be a Lender
hereunder or shall be an Affiliate of a Lender), the processing and
recordation fee referred to in Section 9.04(b) and, if required, the written
consent of each Borrower to such assignment and, if required, upon granting
its own consent to such assignment, the Agent shall (i) accept such
Assignment and Acceptance, (ii) record the

information contained therein in the Register and (iii) give prompt notice
thereof to the Issuing Bank and the Lenders. Within five Business Days after

Note payable to the order of such assignee in a principal amount equal to the
Commitment assumed by it pursuant to such Assignment and Acceptance and, if
the assigning Lender has retained a portion of the Commitment, a new Note
payable to the order of such assigning Lender in a principal amount equal to
the remaining portion of the Commitment retained by it. Such new Note or
Notes shall be in an aggregate principal amount equal to the aggregate
principal amount of such surrendered Note; such new Note or Notes shall be
dated the date of the surrendered Note which it replaces and shall otherwise
be in substantially the form of Exhibit A hereto. Cancelled Notes shall be
returned to the Borrowers.

(f) Each Lender may sell participations in all or a portion of its
interests, rights and obligations under this Amended Agreement (including all
or a portion of its Commitment, the Loans owing to it, the Notes held by it
and the participations in Letters of Credit held by it) to one or more
participants; PROVIDED, HOWEVER, that (i) such Lender's obligations under
this Amended Agreement shall remain unchanged and such Lender shall remain
solely responsible to the other parties hereto for the performance of such
obligations, (ii) except in the case of a participation to a Lender or an
Affiliate of a Lender, such Lender shall have obtained the prior written
consent to such participation of the Borrowers and the Agent (which consent
shall not be unreasonably withheld), (iii) the participating banks or other
entities shall be entitled to the benefit of the cost protection provisions
contained in Sections 2.12, 2.14 and 2.18 to the same extent as if they were
Lenders and (iv) the Borrowers, the Agent, the Issuing Bank and the other
Lenders shall continue to deal solely and directly with such Lender in
connection with such Lender's interests, rights and obligations under this
Amended Agreement, and such Lender shall retain the sole right to enforce the
obligations of the Borrowers relating to the Loans and to approve any
amendment, modification or waiver of any provision of this Amended Agreement
(other than amendments, modifications or waivers decreasing the principal
amount of any Loan, extending the Maturity Date, extending any date for the
payment of any interest on any Loan or any Fees, waiving or excusing any such
payment or any part thereof, decreasing the rate of interest on any Loan,
changing or extending any Commitment or decreasing any Fees, reducing the
amount of or postponing the date fixed for any reimbursement of a Letter of
Credit Disbursement or, except in connection with a disposition approved by
the Required Lenders, permitting the release or sharing of any Collateral
under any Pledge Agreement or permitting the release of any guarantor from a
Guarantee Agreement or increasing the aggregate Commitments of the Lenders).
An Approved Extension shall not be deemed an amendment, modification or
waiver of any provision of this Amended Agreement for purposes of the
foregoing.

(g) Any Lender or participant may, in connection with any assignment or
participation or proposed assignment or participation pursuant to this
Section 9.04, disclose to the assignee or participant or proposed assignee or
participant any information relating to Horizon or any of the Subsidiaries
furnished to such Lender by or on behalf of Horizon or any of the
Subsidiaries; PROVIDED that, prior to any such disclosure of information
designated by Horizon

as confidential, each such assignee or participant or proposed assignee or
participant shall execute an agreement whereby such assignee or participant
shall agree (subject to customary exceptions) to preserve the confidentiality
of such confidential information.

(h) Any Lender may at any time assign all or any portion of its rights
under this Amended Agreement and the Notes issued to it to a Federal Reserve
Bank; PROVIDED that no such assignment shall release a Lender from any of its
obligations hereunder.

(i) Neither Borrower shall assign or delegate any of its rights or
duties hereunder or any interest herein (whether voluntarily, by operation of
law or otherwise). Any purported assignment or delegation in violation of
the foregoing shall be void.

SECTION 9.05. EXPENSES; INDEMNITY. (a) The Borrowers agree to pay
(whether or not the transactions contemplated hereby shall be consummated)
all reasonable out-of-pocket costs and expenses incurred by the Agent or the
Issuing Bank in connection with the preparation, execution and delivery of
this Amended Agreement and the other Loan Documents, the syndication or
closing of the Facility, the administration of the Facility or any amendment,
modification or waiver of the provisions hereof or thereof or incurred by the
Agent, the Issuing Bank or any Lender in connection with the enforcement or
protection of the rights of the Agent, the Issuing Bank and the Lenders under
this Amended Agreement and the other Loan Documents or in connection with the
Loans made under the Facility, the Notes issued under the Facility or the
Letters of Credit issued under the Facility, including the reasonable fees,
charges and disbursements of (i) Fennebresque, Clark, ▇▇▇▇▇▇▇▇ & Hay, counsel
for the Agent, (ii) any third party consultants retained to assist the Agent
in analyzing any due diligence issues with respect to the Borrowers and (iii)
in connection with any such enforcement or protection, any other counsel for
the Agent, the Issuing Bank or any Lender (including the non-duplicative
allocated fees and expenses of any in-house staff counsel).

(b) To the fullest extent permitted under applicable law, the
Borrowers agree to indemnify each of the Agent, the Issuing Bank, the
Lenders, the Affiliates of the Agent, the Issuing Bank or the Lenders, and
their respective directors, officers, employees, agents and Controlling
persons (each, an "INDEMNIFIED PARTY") from and against any and all losses,
claims (whether valid or not), damages and liabilities, joint or several, to
which such Indemnified Party may become subject, related to or arising out of
(i) the Tender Offers or the Facility, (ii) the execution or delivery of this
Amended Agreement or any other Loan Document or any agreement or instrument
contemplated hereby or thereby, the performance by the parties hereto or
thereto of their respective obligations, hereunder or thereunder or the
consummation of the Tender Offers and the other transactions contemplated
hereby or thereby, (iii) the use of the Letters of Credit or the proceeds of
the Loans under the Facility or (iv) any claim, litigation, investigation or
proceeding relating to any of the foregoing, whether or not any Indemnified
Party is a party thereto. The Borrowers further agree to reimburse each
Indemnified Party for all expenses (including reasonable attorneys' fees and
expenses) as they are incurred in connection with the investigation of,
preparation for or defense of any pending or threatened claim or any action
or proceeding arising therefrom. Notwithstanding the foregoing, the
obligation to indemnify any Indemnified Party under this Section 9.05(b)
shall

not apply in respect of any loss, claim, damage or liability to the extent
that a court of competent jurisdiction shall have determined by final and
nonappealable judgment that such loss, claim, damage or liability resulted
from such Indemnified Party's willful malfeasance or gross negligence.

(c) To the fullest extent permitted under applicable law, the Borrowers
agree to indemnify each of the Agent, the Issuing Bank, the Lenders and the
other Indemnified Parties from and against any and all losses, claims
(whether valid or not), damages and liabilities, joint or several, to which
such Indemnified Party may become subject, related to or arising out of (i)
any Federal, state, local or other statute, ordinance, order, judgment,
ruling or regulation relating to environmental pollution, regulation or
control affecting Horizon, any of the Subsidiaries or its properties or
assets, (ii) any Hazardous Materials managed by Horizon or any of the
Subsidiaries, (iii) any event, condition or circumstance involving
environmental pollution, regulation or control affecting Horizon or any of
the Subsidiaries or its properties or assets or (iv) any claim, litigation,
investigation or proceeding relating to any of the foregoing, whether or not
any Indemnified Party is a party thereto. The Borrowers further agree to
reimburse each Indemnified Party for all expenses (including reasonable
attorneys' fees and expenses) as they are incurred in connection with the
investigation of, preparation for or defense of any pending or threatened
claim or any action or proceeding arising therefrom. Notwithstanding the
foregoing, the obligation to indemnify any Indemnified Party under this
Section 9.05(c) shall not apply in respect of any loss, claim, damage or
liability to the extent that a court of competent jurisdiction shall have
determined by final and nonappealable judgment that such loss, claim, damage
or liability resulted from (A) such Indemnified Party's willful malfeasance
or gross negligence or (B) a Hazardous Material introduced to a property of
either Borrower or the Subsidiaries after the Agent or any Lender has taken
possession thereof, whether by foreclosure or otherwise.

(d) In the event that the foregoing indemnity of the Borrowers is
unavailable or insufficient to hold an Indemnified Party harmless, then, to
the fullest extent permitted under applicable law, the Borrowers will
contribute to amounts paid or payable by such Indemnified Party in respect of
such Indemnified Party's losses, claims, damages or liabilities in such
proportions as appropriately reflect the relative benefits received by and
fault of the Borrowers and such Indemnified Party in connection with the
matters as to which such losses, claims, damages or liabilities relate and
other equitable considerations.

(e) If any action, proceeding or investigation is commenced, as to
which any Indemnified Party proposes to demand such indemnification, it shall
notify the Borrowers with reasonable promptness; PROVIDED, HOWEVER, that any
failure by such Indemnified Party to notify the Borrowers shall not relieve
the Borrowers from their obligations hereunder except to the extent the
Borrowers are prejudiced thereby. The Borrowers shall be entitled to assume
the defense of any such action, proceeding or investigation, including the
employment of counsel and the payment of all fees and expenses. Each
Indemnified Party shall have the right to employ separate counsel in
connection with any such action, proceeding or investigation and to
participate in the defense thereof, but the fees and expenses of such counsel
shall be paid by such Indemnified Party, unless (i) the Borrowers have failed
to assume the defense and employ

counsel as provided herein, (ii) the Borrowers have agreed in writing to pay
such fees and expenses of separate counsel or (iii) an action, proceeding or
investigation has been commenced against such Indemnified Party and the
Borrowers and representation of both the Borrowers and such Indemnified Party
by the same counsel would be inappropriate because of actual or potential
conflicts of interest between the parties (in the case of any Agent or
Lender, the existence of any such actual or potential conflict of interest to
be determined by such party, taking into account, among other things, any
relevant regulatory concerns). In the case of any circumstance described in
clause (i), (ii) or (iii) of the immediately preceding sentence, the
Borrowers shall be responsible for the reasonable fees and expenses of such
separate counsel; PROVIDED, HOWEVER, that in any event the Borrowers shall
not be required to pay the fees and expenses of more than one separate
counsel (plus appropriate local counsel under the direction of such separate
counsel) for all Indemnified Parties. The Borrowers shall be liable only for
settlement of any claim against an Indemnified Party made with the Borrowers'
written consent.

(f) The provisions of this Section 9.05 shall remain operative and in
full force and effect regardless of the expiration of the term of this
Amended Agreement, the consummation of the transactions contemplated hereby,
the repayment of any of the Loans, the invalidity or unenforceability of any
term or provision of this Amended Agreement or any other Loan Document, or
any investigation made by or on behalf of the Agent or any Lender. All
amounts due under this Section 9.05 shall be payable on written demand
therefor.

SECTION 9.06. RIGHT OF SETOFF. If an Event of Default shall have
occurred and be continuing, each Lender is hereby authorized at any time and
from time to time, to the fullest extent permitted under 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 to or for the credit or the account of either Borrower against any of
and all the obligations of the Borrowers now or hereafter existing under this
Amended Agreement and the other Loan Documents held by such Lender,
irrespective of whether or not such Lender shall have made any demand under
this Amended Agreement or such other Loan Document and although such
obligations may be unmatured. The rights of each Lender under this Section
9.06 are in addition to other rights and remedies (including other rights of
setoff) which such Lender may have.

SECTION 9.07. APPLICABLE LAW. THIS AMENDED AGREEMENT AND THE OTHER
LOAN DOCUMENTS SHALL BE CONSTRUED IN ACCORDANCE WITH AND GOVERNED BY THE LAWS
OF THE STATE OF NEW YORK, EXCEPT TO THE EXTENT THAT THE FEDERAL LAWS OF THE
UNITED STATES OF AMERICA MAY APPLY.

SECTION 9.08. WAIVERS; AMENDMENT. (a) To the fullest extent permitted
under applicable law, no failure or delay of the Agent, the Issuing Bank or
any Lender in exercising any power or right hereunder shall operate as a
waiver thereof, nor shall any single or partial exercise of any such right or
power, or any abandonment or discontinuance of steps to enforce such a right
or power, preclude any other or further exercise thereof or the exercise of
any

other right or power. To the fullest extent permitted under applicable law,
the rights and remedies of the Agent, the Issuing Bank and the Lenders
hereunder and under the other Loan Documents are cumulative and are not
exclusive of any rights or remedies which they would otherwise have. To the
fullest extent permitted under applicable law, no waiver of any provision of
this Amended Agreement or any other Loan Document or consent to any departure
by the Borrowers therefrom shall in any event be effective unless the same
shall be permitted by Section 9.08(b), and then such waiver or consent shall
be effective only in the specific instance and for the purpose for which
given. No notice or demand on the Borrowers in any case shall entitle the
Borrowers to any other or further notice or demand in similar or other
circumstances.

(b) None of this Amended Agreement, the other Loan
Documents nor any provision hereof or thereof may be waived,
amended or modified, except pursuant to an agreement or
agreements in writing entered into by the Borrowers and the
Required Lenders; PROVIDED, HOWEVER, that no such waiver,
amendment or modification shall (i) decrease the principal amount
of any Loan, extend the Maturity Date, extend any date for the
payment of any interest on any Loan or any Fees, or waive or
excuse any such payment or any part thereof, or decrease the rate
of interest on any Loan, without the prior written consent of
each holder of a Note affected thereby, (ii) change or extend the
Commitment or decrease the Fees of any Lender without the prior
written consent of such Lender, (iii) reduce the amount of or
postpone the date fixed for any reimbursement of a Letter of
Credit Disbursement without the prior written consent of each
Lender affected thereby, (iv) except in connection with a
disposition approved by the Required Lenders, permit the release,
transfer or sharing of any Collateral under any Pledge Agreement
or permit the release of any guarantor from any Guarantee
Agreement without the prior written consent of each Lender, (v)
increase the aggregate Commitments of the Lenders without the
prior written consent of each Lender or (vi) amend or modify the
provisions of Section 2.14, 2.15 or 2.16, the provisions of
Section 9.04(i), the provisions of this Section 9.08 or the
definitions of "Required Lenders" or "Consenting Lenders" or
otherwise change the percentage of the Commitments, the
percentage of the aggregate unpaid principal amount of the Notes
or the number of Lenders which shall be required for the Lenders
or any of them to take any action under any provision of this
Amended Agreement or any other Loan Document, without the prior
written consent of each Lender; PROVIDED FURTHER that no such
agreement shall amend, modify or otherwise affect the rights or
duties of the Agent or Issuing Bank hereunder without the prior
written consent of the Agent or the Issuing Bank, as applicable.
An Approved Extension shall not be deemed an amendment,
modification or waiver of any provision of this Amended Agreement
for purposes of the foregoing. Each Lender and each holder of a
Note shall be bound by any waiver, amendment or modification
authorized by this Section 9.08 regardless of whether its Note
shall have been marked to make reference thereto, and any consent
by any Lender or holder of a Note pursuant to this Section 9.08
shall bind any person subsequently acquiring a Note from it,
whether or not such Note shall have been so marked.

SECTION 9.09. INTEREST RATE LIMITATION. It is the
intention of the parties hereto to comply with applicable usury
laws; accordingly, it is agreed that notwithstanding any
provisions to the contrary in this Amended Agreement, the Notes,
the other Loan Documents

or in any of the documents securing payment thereof or otherwise
relating thereto, in no event shall the aggregate of any consideration
that constitutes interest under law applicable to each Lender that is
contracted for, taken, reserved, charged or received under this Amended
Agreement, the Notes, the other Loan Documents or under any of
the aforesaid agreements exceed the maximum amount allowed by
such applicable law. If any such excess of interest contracted
for, charged or received under this Amended Agreement, the Notes,
the other Loan Documents or under the terms of any of the
documents securing payment thereof or otherwise relating thereto,
or if the maturity of the indebtedness evidenced by the Notes is
accelerated in whole or in part, or in the event that all or part
of the principal of or interest on the Notes shall be prepaid, so
that under any of such circumstances the amount of interest
contracted for, charged or received under this Amended Agreement,
the Notes, the other Loan Documents or under any of the documents
securing payment thereof or otherwise relating thereto on the
amount of principal actually outstanding from time to time under
the Notes shall exceed the maximum amount of interest permitted
by applicable usury laws, then in any such event (i) the
provisions of this Section 9.09 shall govern and control, (ii)
neither Horizon, Continental, or any other Subsidiary nor any
other person now or hereafter liable under this Amended Agreement
or the other Loan Documents for the payment of the Notes shall be
obligated to pay in excess of the maximum amount of interest
permitted to be contracted for by, charged to or received from
the person obligated thereon under applicable usury laws, (iii)
any such excess shall be applied as a credit against the then
unpaid principal amount of the Notes or refunded to the person
paying the same, at the holder's option, and (iv) the effective
rate of interest shall be automatically reduced to the maximum
lawful rate of interest permitted under applicable usury laws as
now or hereafter construed by the courts having jurisdiction
thereof. It is further agreed that, without limitation of the
foregoing, all calculations of the rate of interest contracted
for, charged or received under this Amended Agreement, the Notes,
the other Loan Documents or under such other documents or
instruments which are made for the purpose of determining whether
such rate exceeds the maximum lawful rate of interest shall be
made, to the extent permitted by applicable usury laws, by
amortizing, prorating, allocating and spreading in equal parts
during the period of the full stated term of the indebtedness
evidenced by the Notes, all interest at any time contracted for,
charged or received from either Borrower or otherwise by the
holder or holders thereof in connection with the Notes, the other
Loan Documents or this Amended Agreement.

SECTION 9.10. ENTIRE AGREEMENT. (a) This Amended
Agreement, the other Loan Documents and the Fee Letter constitute
the entire contract among the parties relative to the subject
matter hereof and thereof. Any agreement previously entered into
among the parties with respect to the subject matter hereof and
thereof is superseded by this Amended Agreement, the other Loan
Documents and the Fee Letter. Nothing in this Amended Agreement,
the other Loan Documents or the Fee Letter, expressed or implied,
is intended to confer upon any party, other than the parties
hereto and thereto and the other Secured Parties, any rights,
remedies, obligations or liabilities under or by reason of this
Amended Agreement, the other Loan Documents or the Fee Letters.

(b) THIS WRITTEN AGREEMENT, THE NOTES, THE OTHER LOAN
DOCUMENTS, AND THE INSTRUMENTS AND DOCUMENTS EXECUTED IN

CONNECTION HEREWITH, REPRESENT THE FINAL AGREEMENT BETWEEN THE
PARTIES AND MAY NOT BE CONTRADICTED BY EVIDENCE OF PRIOR,
CONTEMPORANEOUS, OR SUBSEQUENT ORAL AGREEMENTS OF THE PARTIES.
THERE ARE NO UNWRITTEN ORAL AGREEMENTS BETWEEN THE PARTIES.

SECTION 9.11. SEVERABILITY. To the fullest extent
permitted under applicable law, in the event any one or more of
the provisions contained in this Amended Agreement or in any
other Loan Document should be held invalid, illegal or
unenforceable in any respect, the validity, legality and
enforceability of the remaining provisions contained herein and
therein shall not in any way be affected or impaired thereby. To
the fullest extent permitted under applicable law, the parties
shall endeavor in good-faith negotiations to replace the invalid,
illegal or unenforceable provisions with valid provisions the
economic effect of which comes as close as possible to that of
the invalid, illegal or unenforceable provisions.

SECTION 9.12. COUNTERPARTS. This Amended Agreement may be
executed in two or more counterparts, each of which shall
constitute an original but all of which when taken together shall
constitute but one contract.

SECTION 9.13. HEADINGS. Article and Section headings and
the Table of Contents used herein are for convenience of
reference only, are not part of this Amended Agreement and are
not to affect the construction of, or to be taken into
consideration in interpreting, this Amended Agreement.

SECTION 9.14. JURISDICTION; CONSENT TO SERVICE OF PROCESS.
(a) To the fullest extent permitted under applicable law, each
Borrower hereby irrevocably and unconditionally submits, for
itself and its property, to the nonexclusive jurisdiction of any
New York State court or Federal court of the United States of
America sitting in New York, New York and any appellate court
from any thereof, in any action or proceeding arising out of or
relating to this Amended Agreement or the other Loan Documents,
or for recognition or enforcement of any judgment, and each of
the parties hereto hereby irrevocably and unconditionally agrees
that all claims in respect of any such action or proceeding may
be heard and determined in such New York State or, to the extent
permitted under law, in such Federal court. To the fullest
extent permitted under applicable law, each of the parties hereto
agrees that a final judgment in any such action or proceeding
shall be conclusive and may be enforced in other jurisdictions by
suit on the judgment or in any other manner provided by law.
Nothing in this Amended Agreement shall affect any right that the
Agent, the Issuing Bank or any Lender may otherwise have to bring
any action or proceeding relating to this Amended Agreement or
the other Loan Documents against either Borrower or its
properties in the courts of any jurisdiction.

(b) Each Borrower hereby irrevocably and unconditionally
waives, to the fullest extent it may legally and effectively do
so, any objection which it may now or hereafter have to the
laying of venue of any suit, action or proceeding arising out of
or relating to this Amended Agreement or the other Loan Documents
in any New York State court or Federal court of the United States
of America sitting in New York, New York. Each of the parties
hereto hereby

irrevocably waives, to the fullest extent permitted under law, the
defense of an inconvenient forum to the maintenance of such action or
proceeding in any such court.

(c) To the fullest extent permitted under applicable law,
each party to this Amended Agreement irrevocably consents to
service of process in the manner provided for notices in
Section 9.01. Nothing in this Amended Agreement will affect the
right of any party to this Amended Agreement to serve process in
any other manner permitted under law.

SECTION 9.15. JOINT AND SEVERAL LIABILITY. (a) All
obligations of the Borrowers hereunder are joint and several in
each and every particular. The obligations of the Borrowers
under this Amended Agreement are independent of each other, and a
separate action or actions may be brought and prosecuted against
either Borrower to enforce this Amended Agreement, irrespective
of whether any action is brought against the other Borrower or
whether the other Borrower is joined in any such action or
actions. All obligations of each Borrower hereunder are primary
obligations concerning which such Borrower is the principal
obligor.

(b) To the fullest extent permitted under applicable law,
each Borrower hereby waives marshalling of assets and liabilities
and sale in inverse order of alienation and waives presentment
to, demand of payment from and protest to the other Borrower or
any Subsidiary Guarantor of any of the Obligations or any of the
Guaranteed Obligations (as defined in each of the Guarantee
Agreements), and also waives promptness, diligence, notice of
acceptance hereunder, any other notice with respect to any of the
Obligations and this Agreement and any requirement that the Agent
or any other Secured Party protect, secure, perfect or insure any
Lien or any property subject thereto. Each Borrower further
waives to the fullest extent permitted under applicable law any
right to require that resort be had by the Agent or any other
Secured Party to any security held for payment of the Obligations
or the Guaranteed Obligations or to any balance of any deposit,
account or credit on the books of the Agent or any other Secured
Party in favor of the other Borrower or any other person. Each
Borrower hereby waives and releases any and all rights of
contribution from the other Borrower or any Subsidiary Guarantor
for payment of the Obligations or the Guaranteed Obligations, as
applicable, to the fullest extent permitted under applicable law.
Each Borrower hereby consents and agrees to each of the following
to the fullest extent permitted by law, and agrees that such
Borrower's obligations under this Agreement shall not be
released, diminished, impaired, reduced or adversely affected by
any of the following, and waives any rights (including rights to
notice) which such Borrower might otherwise have as a result of
or in connection with any of the following:

(i) any renewal, extension, modification, increase,
decrease, alteration or rearrangement of all or any part of
the Obligations or the Guaranteed Obligations or any
instrument executed in connection therewith, or any contract
or understanding with either Borrower, the Agent, the other
Secured Parties, or any of them, or any Subsidiary
Guarantor, pertaining to the Obligations or the Guaranteed
Obligations;

(ii) any adjustment, indulgence, forbearance or
compromise that might be granted or given by the Agent or
any other Secured Party to either Borrower, any

Subsidiary Guarantor or any other person liable on the Obligations
or the Guaranteed Obligations; or the failure of the Agent or
any other Secured Party to assert any claim or demand or to
exercise any right or remedy against either Borrower, any
Subsidiary Guarantor under the provisions of any Loan
Document or otherwise; or any rescission, waiver, amendment
or modification of, or any release from any of the terms or
provisions of, any Loan Document, any guarantee or any other
agreement;

(iii) the insolvency, bankruptcy, arrangement,
adjustment, composition, liquidation, disability,
dissolution or lack of power of either Borrower, any
Subsidiary Guarantor or any other person at any time liable
for the payment of all or part of the Obligations or the
Guaranteed Obligations; or any dissolution of either
Borrower, any Subsidiary Guarantor, or any change,
restructuring or termination of the corporate structure or
existence of either Borrower or any Subsidiary Guarantor, or
any sale, lease or transfer of any or all of the assets of
either Borrower or any Subsidiary Guarantor, or any change
in the shareholders, partners, or members of either Borrower
or any Subsidiary Guarantor; or any default, failure or
delay, willful or otherwise, in the performance of the
Obligations or the Guaranteed Obligations;

(iv) the invalidity, illegality or unenforceability of
all or any part of the Obligations or the Guaranteed
Obligations, or any document or agreement executed in
connection with the Obligations or the Guaranteed
Obligations, for any reason whatsoever, including the fact
that the Obligations, or any part thereof, exceed the amount
permitted by law, the act of creating the Obligations or any
part thereof is ULTRA ▇▇▇▇▇, the officers or representatives
executing the documents or otherwise creating the
Obligations or the Guaranteed Obligations acted in excess of
their authority, the Obligations violate applicable usury
laws, either Borrower or any Subsidiary Guarantor has valid
defenses, claims or offsets (whether at law, in equity or by
agreement) which render the Obligations or the Guaranteed
Obligations, as applicable, wholly or partially
uncollectible from all or any of them, the creation,
performance or repayment of the Obligations or the
Guaranteed Obligations (or the execution, delivery and
performance of any document or instrument representing part
of the Obligations or the Guaranteed Obligations or executed
in connection with the Obligations or the Guaranteed
Obligations or given to secure the repayment of the
Obligations or the Guaranteed Obligations) is illegal,
uncollectible, legally impossible or unenforceable, or the
documents or instruments pertaining to the Obligations or
the Guaranteed Obligations have been forged or otherwise are
irregular or not genuine or authentic;

(v) any full or partial release of the liability of
either Borrower on the Obligations or any part thereof, of
any Subsidiary Guarantor now or hereafter liable, whether
directly or indirectly, jointly, severally, or jointly and
severally, to pay, perform, guarantee or assure the payment
of the Guaranteed Obligations or any part thereof, it being
recognized, acknowledged and agreed by each Borrower that
such Borrower may be required to pay the Obligations in full
without assistance or support of any other person, and such
Borrower has not been induced to enter into this Agreement
on the basis of a contemplation, belief, understanding or
agreement that

other parties other than such Borrower will be liable to
perform the Obligations, or the Secured Parties will look to
other parties to perform the Obligations;

(vi) any demand for or acceleration of any payment by
either Borrower to the Agent or any other Secured Party
being stayed under Title 11 of the United States Code or any
similar Federal or state law or any payment by either
Borrower to the Agent or any other Secured Party being held
to constitute a preference under Title 11 of the United
States Code or any similar Federal or state law, or for any
reason the Agent or any other Secured Party being required
to refund such payment or pay such amount to such Borrower
or someone else;

(vii) any other circumstance (including any statute
of limitations) that might in any manner or to any extent
otherwise constitute a defense available to, vary the risk
of, or operate as a discharge of either Borrower or any
Subsidiary Guarantor as a matter of law or equity.

All waivers of each Borrower herein contained shall be without
prejudice to the Agent at its option to proceed against either
Borrower, any Subsidiary Guarantor or any other person, whether
by separate action or by joinder. Without limiting the
generality of the foregoing and to the fullest extent permitted
under applicable law, each Borrower expressly waives each and
every right to which it may be entitled by virtue of the
suretyship law of the State of New York.
