     granted within the previous 10 years under this Scheme and any other share
     option scheme (other than a savings-related share option scheme) adopted by
     the Company, it shall not exceed 5 per cent of the Ordinary Share Capital
     in issue on the day preceding that date.

(b)  No Option to subscribe for Scheme Shares will be granted after Flotation
     during any period of 3 years while this Scheme remains in force if
     immediately after the grant of such Options the aggregate of:

     (i)  the nominal amount of Ordinary Share Capital issued or remaining
          issuable pursuant to options granted during such 3 year period under
          this Scheme and under any other share option scheme adopted by the
          Company; and

     (ii) the nominal amount of Ordinary Share Capital issued under any other
          Employees' Share Scheme of the Company during the same 3 year period

     would exceed 3 per cent of the nominal amount of Ordinary Share Capital in
     issue at that time.

     commencing with the Adoption Date the maximum nominal amount of Scheme

AVAILABILITY OF AUTHORISED CAPITAL AND SCHEME SHARES

     unissued Scheme Shares or shall procure that sufficient Scheme Shares are
     available for transfer to satisfy the exercise to the full extent still
     possible of all Options which have neither lapsed nor been fully exercised
     taking account of any other obligations of the Company to provide shares of
     the same class as Scheme Shares.

VARIATION OF CAPITAL AND ADJUSTMENT OF OPTIONS

(b)  In the event of any capitalization issue or rights issue or rights offer or
     any reduction, sub-division, consolidation or other variation of the
     capital of the Company, the number of Scheme Shares comprised in any Option
     over Scheme Shares in the Company and/or the Option Price may be adjusted
     by the Directors (including retrospective adjustments where appropriate) in
     such manner as the Directors consider to be in their opinion fair and
     reasonable provided always that no adjustment shall have effect after the
     date of adjustment unless the Board of Inland Revenue has approved the
     adjustment. Except in the case of an Option over Scheme Shares already in
     issue, no adjustment shall be made which would cause the Option Price to be
     less than the nominal value of that Scheme Share. Notice of any adjustment
     shall be given to those Option-holders affected by such adjustment by the
     Directors who may call in Option Certificates for endorsement.

4    LIMITS ON AN EMPLOYEE'S PARTICIPATION

LIMIT BY REFERENCE TO ALL EXECUTIVE SHARE OPTION SCHEMES

(b)  An Employee shall not be granted an Option after Flotation which would at
     the proposed Date of Grant cause the aggregate of the Market Value of the
     shares which he has or might have subscribed or may in future subscribe or
     might in future have subscribed in respect of options granted in the ten
     years preceding such Date of Grant on the exercise of an option granted
     under this and any other share option scheme established by the Company
     (other than a savings-related share option scheme) but excluding any Option
     which has lapsed and any Option which was granted prior to Flotation (and
     to the extent that the Option to be granted at such Date of Grant is a
     replacement Option also excluding any Option which has been exercised) to
     exceed four times the greater of:-

     (i)  the annual rate of the Employee's total remuneration (exclusive of
          bonuses, commissions and benefits-in-kind) from the Group as at the
          day immediately preceding the Date of Grant of that Option; or

     (ii) the total remuneration (inclusive of bonuses and commissions but
          exclusive of benefits-in-kind) payable to the Employee by the Group in
          the 12 months ending on the last day of the month immediately
          preceding the month in which the Date of Grant falls; or

     (iii) the total remuneration (inclusive of bonuses and commissions but
          exclusive of benefits-in-kind) payable to the Employee by the Group
          for any 12 month period in which the Date of Grant occurs.

5    GRANT OF AN OPTION

GENERAL

(a)  Subject to statutory restrictions and subject to the Rules of this Scheme
     the Grantor may grant any Employee an Option over such number of Scheme
     Shares as the Grantor may determine.

TIMING OF GRANT

(b)  Subject to (c) below Options shall only be granted:

     (i)  except during a prescribed period mentioned in (iii) below, at any

          time within the period of 6 weeks immediately succeeding the
          announcement of the Company's annual or interim results provided
          always that no Option shall be granted the Market Value of which would
          fall to be determined by reference to a dealing day or days preceding
          any such announcement; or

    (iii) at any other time if the Grantor considers that exceptional
          circumstances exist to justify the grant at such other time provided
          always that no Option shall be granted the Market Value of which would
          fall to be determined by reference to a dealing day

                                       11
<PAGE>   13

          or days within a period (which restricts directors and certain
          employees and those connected with them from dealing in the Company's
          shares when in possession of unpublished price sensitive information)
          whether as prescribed by the Model Code of The London Stock Exchange,
          the provisions of the Criminal Justice Act 1993, the Company's code on
          insider dealing or otherwise.

(c)  No Option shall be granted more than 10 years after the Adoption Date or to
     any Employee if the Date of Grant is less than two years before his normal
     retirement date under his contract of employment. If the Employee's normal
     retirement date is uncertain the Grantor may determine his normal
     retirement date for the purposes of the Scheme.

ADDITIONAL CONDITIONS

(d)  The Grantor when granting any Option may in their absolute discretion
     impose any conditions and limitations (additional to any conditions and
     limitations contained in any other of these Rules) upon the exercise of
     such Option provided that such additional conditions and limitations
     shall:-

     (i)  be objective, specified at the date of Grant and set out in full in,
          or details given with, the Option Certificate; and

     (ii) be such that rights to exercise such Option after the fulfilment or
          attainment of any conditions and limitations so specified shall not be
          dependent upon the further discretion of any person; and

    (iii) not be capable of amendment, variation or waiver unless an event
          occurs which causes the Committee to consider that a waived, varied or
          amended condition would be a fairer measure of performance and would
          be no more difficult to satisfy.

OPTION CERTIFICATE

(e)  Upon the grant of an Option each Option-holder shall be issued with a
     certificate which shall be executed by the Company in such manner so as to
     take effect in law as a deed specifying the Date of Grant, the number of
     Scheme Shares the subject of the Option, the Option Price, the Acquisition
     Price and any conditions and limitations which may have been imposed in
     accordance with Rule 5(d).

RENUNCIATION OF OPTIONS

(f)  Any Option may be renounced in whole or in part by the Option-holder by
     deed to the Company received not later than 30 days after the Date of Grant
     of that Option in which case the Option shall for all purposes to that
     extent be deemed never to have been granted.

6    NON TRANSFERABILITY OF OPTIONS

Save as provided in Rule 7(e) no Option nor any right thereunder shall be
capable of being transferred, assigned or charged. Any such purported transfer,
assignment or charge shall result in the cancellation of the Option.

7     RIGHTS TO EXERCISE OPTIONS

GENERAL

(a)  Save as provided in Rules 7(d) to 7(g) and 9 an Option:

     (i)  shall not be exercisable before the expiry of 3 years from its Date of
          Grant; and

     (ii) shall not be exercisable until any additional conditions and
          limitations imposed on the Option (and which have not been waived) in
          accordance with Rule 5(d) have been fulfilled; but

    (iii) subject to Rules 7(b) and 7(c) may thereafter be exercised in whole
          or in part at any time or from time to time provided that, unless the
          Directors determines otherwise, the exercise would not be at a time
          when the acquisition or disposal of Scheme Shares by a director or
          employee of a Group Company would be in contravention of the Model
          Code of the London Stock Exchange, the provisions of the Criminal
          Justice Act 1993, the Company's code on insider dealing or otherwise
          (which restricts directors and certain employees and those connected
          with them from dealing in the Company's shares when in possession of
          unpublished price sensitive information).

(b)  No Option is exercisable later than 10 years from its Date of Grant.

(c)  No Option may be exercised by an Option-holder at any time when he is
     precluded by paragraph 8 of Schedule 9 from participating in this Scheme.

TRANSFER TO ANOTHER COUNTRY

(d)  If an Option-holder, while continuing to hold an office or employment
     within the Group is to be transferred to work in another country and the
     Directors are satisfied that as a result of that transfer either:

     (i)  he will suffer a tax disadvantage upon exercising his Option(s); or

     (ii) he will become subject to restrictions on his ability to exercise his
          Option(s) or to deal in the Scheme Shares obtained upon exercise of
          his Option(s)

     the Option-holder may subject to Rules 7(b) and 7(c) exercise all or any of
     his Options in whole or in part in the period commencing three months
     before and ending three months after the date of the transfer (but so that
     any exercise before the date of transfer shall be conditional upon such
     transfer taking place). Upon the expiry of such period any Option, to the
     extent unexercised, shall cease to be exercisable under this Rule 7(d) and
     shall be exercisable at such other time as provided in these Rules.

DEATH

(e)  If an Option-holder dies, his legal personal representatives may exercise
     all or any of his Options in whole or in part within 12 months of his death
     and at the expiry thereof his Options shall, to the extent unexercised,
     lapse.

<PAGE>   15

CESSATION OF EMPLOYMENT IN SPECIAL CIRCUMSTANCES

(f)  If an Option-holder shall cease to be employed within the Group by reason
     of:

     (i)  injury or disability (evidenced to the satisfaction of the Directors)
          or redundancy within the meaning of the Employment Protection
          (Consolidation) Act 1978; or

     (ii) retirement on reaching his normal retirement age under his contract of
          employment

     he may, subject to Rules 7(b) and 7(c) exercise all or any of his Options
     in whole or in part during the period ending 6 months after the date of
     such cessation.

(g)  If an Option-holder shall cease to be employed within the Group solely by
     reason that the company by which he is for the time being employed then
     ceases to be a member of the Group or by reason of the transfer of the
     undertaking or part of the undertaking in which the Option-holder is
     employed to a transferee which is not in the Group, then, he may, subject
     to Rules 7(b) and 7(c), exercise all or any of his Options in whole or in
     part during the period ending 6 months after the date of such cessation or
     transfer as the case may be.

CESSATION OF EMPLOYMENT IN OTHER CIRCUMSTANCES

(h)  If an Option-holder gives notice to terminate his employment such that he
     shall cease to be employed within the Group for a reason not falling within
     Rules 7(f) or 7(g) all his Options shall cease to be exercisable and shall
     lapse on the date such employment ceases save that the Directors may in
     their absolute discretion, but subject to Rules 7(a) to 7(c), prior to the
     cessation of employment consent to the exercise of any such Option in whole
     or in part to the extent determined by the Directors during the period
     within 6 months (or such other period as may be determined by the
     Directors) after such cessation and at the expiry of which any such Option
     shall, to the extent unexercised, lapse.

(i)  If an Option-holder is given notice terminating his employment such that he
     shall cease to be employed within the Group in circumstances not involving
     misconduct or impropriety on his part and for a reason not falling within
     Rules 7(f) or 7(g), he may, subject to Rules 7(a) to 7(c) exercise all or
     any of his Options in whole or in part during the period within 6 months
     after such cessation or such longer period as may be determined by the
     Directors acting fairly and reasonably, provided that the period so
     determined shall not exceed the maximum period permitted by Rule 7(j), and
     at the expiry of the said period any Option(s) shall, to the extent
     unexercised, lapse.

DISCRETION TO EXTEND EXERCISE PERIOD

(j)  The Directors may in their absolute discretion but subject to Rules 7(b)
     and 7(c) extend the periods of 6 months specified in Rules 7(f) to 7(i), to
     such longer period as they may determine not exceeding a period which
     expires 3 years and 6 months after the Date of Grant or, if longer, 3 years
     and 6 months after the last occasion on which the Option-holder exercised
     an Option in circumstances qualifying for relief from income tax under
     section 185 of the Act. At the expiry of the period specified in Rules 7(f)
     to 7(i), as the case may be or such longer period as may have been
     determined under this Rule 7(j) any Options held by the Option-holder
     concerned shall, to the extent unexercised, lapse.

<PAGE>   16
8     LOSS OF OFFICE OR EMPLOYMENT

(a)  The grant of an Option does not form part of the Option-holder's
     entitlement to remuneration or benefits pursuant to his contract of
     employment nor does the existence of a contract of employment between an
     Employee and any company give such Employee any right or entitlement to
     have an Option granted to him in respect of any number of Scheme Shares or
     any expectation that an Option might be granted to him whether subject to
     any conditions or at all.

(b)  The rights and obligations of an Option-holder under the terms and
     conditions of his office or employment shall not be affected by his
     participation in the Scheme or any right he may have to participate in the
     Scheme.

(c)  An individual who participates in the Scheme waives all and any rights to
     compensation or damages in consequence of the termination of his office or
     employment with any company for any reason whatsoever in so far as those
     rights arise, or may arise, from his ceasing to have rights under or be
     entitled to exercise any Option under the Scheme as a result of such
     termination or from the loss or diminution of value of such rights or
     entitlements. If necessary, the Option-holder's terms of employment shall
     be varied accordingly.

     has become an Acquiring Company the Directors shall as soon as practicable
     thereafter notify every Option-holder accordingly and each Option-holder
     may subject to Rules 7(b) and 7(c), within the Appropriate Period:

     (i)  exercise all or any of his Options to acquire Scheme Shares (as the
          case may be) in whole or in part (but in the case of a Compromise
          Rules 9(aa) to 9(ae) shall apply); and

     (ii) to the extent that an Option to acquire Scheme Shares (as the case may
          be) is not or has not been exercised, execute, with the consent of the
          Acquiring Company, an Option Rollover by a notice in writing in a form
          prescribed by the directors of the Acquiring Company.

(aa) Where a Compromise is proposed between the Company and its members:

     (i)  Options to acquire Scheme Shares which prior to the date of any
          general meeting of the members ordered by the court have become
          exercisable pursuant to the Rules of this Scheme excluding Rule 9(ab)
          shall, subject to Rules 9(ac) to 9(ae), remain exercisable and may at
          the election of the Option-holder be exercised on the basis set out in
          Rule 9(ab); and

     (ii) Rule 9(ab) shall apply to any Option to acquire Scheme Shares not

     exercise is permitted under this Rule 9(ab):

     (i)  notice of exercise shall be in such form as may be prescribed by the
          Directors; and

     (ii) notwithstanding any other provision in this Scheme, the date of
          exercise of all Options exercised conditionally pursuant to this Rule
          9(ab) shall be the date on which the court sanctions the Compromise.

(ac) Notwithstanding any other Rule in this Scheme, unless the Directors
     determine otherwise, no notice of exercise of an Option shall be effective
     if received on or after the day on which it is anticipated that the court
     will sanction the Compromise.

(ad) If after six months from the date of the meeting ordered by the court to
     consider the Compromise referred to in Rule 9(aa) the court has not
     sanctioned the Compromise, the conditional exercise of Options under Rule
     9(ab) shall be of no effect and Rules 9(aa) and 9(ac) shall cease to apply
     in relation to that Compromise.

(ae) Upon the Compromise becoming effective, any Options, to the extent
     unexercised, shall lapse.

(b)  To the extent that any Option which has become exercisable and/or capable
     of being Rolled-over, pursuant to Rule 9(a)(i) or 9(a)(ii), has not been
     exercised and/or Rolled-over at the expiry of the Appropriate Period it
     shall thereupon continue to subsist unless shares cease to be Scheme Shares
     or the Directors determine otherwise provided always that such
     determination shall apply to all subsisting Options to acquire Scheme
     Shares. Options which continue to subsist shall be subject to the same
     terms and conditions that applied before the date of the change of Control
     or service of the Section 429 Notice (as the case may be). Where the
     Directors have determined otherwise they shall notify all Option-holders to
     whom such determination applies.

(c)  For the purposes of an Option Rollover the new rights shall only be
     regarded as equivalent to the old rights if:

     (i)  the shares to which they relate satisfy the conditions of paragraphs
          10 to 14 of Schedule 9; and

     (ii) the new rights are exercisable in the same manner as the old rights
          and subject to the provisions of this Scheme as it had effect
          immediately before an Option Rollover; and

    (iii) the total Market Value of Scheme Shares subject to an Option which is
          being Rolled-over is equal immediately before such Option Rollover to
          the total market value (determined in accordance with Part VIII of the
          Taxation of Chargeable Gains Act 1992) of the shares in respect of
          which an Option-holder's new rights are being granted immediately
          after such Option Rollover; and

                                       16
<PAGE>   18

     (iv) the total amount payable in respect of the exercise in full of an
          Option following an Option Rollover is equal to the total Acquisition
          Price immediately preceding such Option Rollover.

(d)  For the purposes of any application of the provisions of this Scheme,
     following an Option Rollover any new rights granted pursuant to Rule 9(a)
     shall be regarded as having been granted at the time the corresponding old
     rights were granted. With effect from the Option Rollover, the new rights
     shall be subject to the provisions of the Scheme as it had effect in
     relation to the Options which have been released, except that Rule 11 shall
     not apply.

CHANGE IN CONTROL OF THE COMPANY - ACQUIRING PERSON

(e)  If after the Adoption Date, a person has become an Acquiring Person the
     Directors shall, as soon as practicable thereafter, notify every
     Option-holder accordingly and each Option-holder may, subject to Rules 7(b)
     and 7(c), within the Appropriate Period exercise all or any of his Options
     to acquire Scheme Shares in whole or in part and to the extent that any
     Option which has become exercisable pursuant to this Rule 9(e) has not been
     exercised at the expiry of the Appropriate Period it shall thereupon
     continue to subsist to the extent unexercised unless the Scheme Shares
     cease to exist or the Directors determine otherwise. Options which continue
     to subsist shall be subject to the same terms and conditions which applied
     before the change of Control or the general offer was made or the Section
     429 Notice was served (as the case may be). When the Directors have
     determined otherwise, it shall notify all Option-holders to whom such
     determination applies.

CHANGES TO SCHEME SHARE CLASS OR RIGHTS

(f)  If notice is duly given of a general meeting of the Company at which a
     resolution will be proposed whereby:

          be altered; or

     (ii) the rights attaching to shares which for the time being constitute
          Scheme Shares will be altered

     so that such shares will cease to be Scheme Shares an Option to acquire
     Scheme Shares shall, subject to Rules 7(b) and 7(c) be exercisable in whole
     or in part (but so that any exercise hereunder shall be conditional upon
     such resolution being passed) at any time thereafter until such resolution
     is duly passed or defeated or the general meeting concluded or adjourned,
     sine die, whichever shall first occur. If such a resolution is passed, an
     Option shall, to the extent unexercised, thereupon lapse.

LIQUIDATION

     part (but so that any exercise hereunder shall be conditional upon such
     resolution being passed) at any time thereafter until the resolution is
     duly passed or defeated or the general meeting concluded or adjourned sine
     die, whichever shall first occur.

                                       17

     unexercised, thereupon lapse.

     Option-holder shall, subject to Rules 7(b) and 7(c), be entitled to

     that the issue of Scheme Shares pursuant to such exercise is authorised by
     the administrator(s) or the court.

VOLUNTARY ARRANGEMENT

(i)  If a voluntary arrangement is proposed in relation to the Company pursuant
     to Part II of the Insolvency (Northern Ireland) Order 1989, each

     exercise his Option to acquire Scheme Shares in that company in whole or in
     part within 14 days after the date of despatch of any notices of meetings
     summoned under Article 16 of the Insolvency (Northern Ireland) Order 1989

10   EXERCISE OF OPTIONS AND LISTING OF SHARES

PROCEDURES ON EXERCISE

(a)  Exercise of an Option, or of new rights under this Scheme shall be effected
     by a notice of exercise in writing in a form prescribed from time to time
     by the Directors lodged with the Secretary of the Company or at its office
     specifying the number of Scheme Shares in respect of which the Option is
     being exercised and accompanied by payment in full of the Acquisition Price
     for the Scheme Shares concerned. Payment may be made by banker's draft or
     cheque provided that if the cheque is not cleared the Employee shall be
     deemed never to have exercised his Option and the Company will be under no
     obligation to provide any Scheme Shares for him. Notwithstanding anything
     to the contrary therein contained such notice shall (Other than in the
     circumstances mentioned in the immediately preceding proviso and/or in Rule
     9(g) above) take effect upon receipt of notice and payment in full and such
     day shall constitute for all purposes the date of exercise of such Option
     and , unless otherwise agreed between the Company and the Option-holder the
     Secretary to the Company shall procure that the relevant Scheme Shares in
     respect of an Option shall be transferred (or issued as the case may be)
     within 28 days thereafter. The Option Certificate should also be lodged but
     failure to do so will not invalidate the exercise of the Option. The
     Company will keep a suitable form of notice available, so that an
     Option-holder desirous of exercising an Option may obtain copies thereof
     from the Secretary of the Company. In the case of a partial exercise of an
     Option, the Company shall deliver an Option Certificate in relation to the
     balance.

(b)  All transfers and all allotments of Scheme Shares shall be subject to any
     necessary consents of HM Treasury or other authorities in the United
     Kingdom or elsewhere under enactments or regulations for the time being in
     force and it shall be the responsibility of the Option-holder to comply
     with any requirements to be fulfilled in order to obtain or obviate the
     necessity for any such consent.

RIGHTS ATTACHING TO SCHEME SHARES

(c)  Scheme Shares transferred pursuant to the Scheme will be transferred
     without the benefit of any rights attaching thereto by reference to a
     record date preceding the date of exercise. Save as regards rights
     attaching to Scheme Shares by reference to a record date prior to the date
     on which the Scheme Shares are allotted and issued, Scheme Shares issued
     upon the exercise of Options to acquire Scheme Shares shall be identical
     and rank pari passu in all respects with the shares of the same class then
     in issue.

LISTING

(d)  At any time when the Scheme Shares are listed on The Stock Exchange, the
     Company shall use its best endeavours to ensure that as soon as practicable
     after the allotment of any Scheme Shares under this Scheme the same shall
     be admitted to the Official List of the Council of The London Stock
     Exchange or any other appropriate investment exchange recognised for the
     purposes of the Financial Services Act 1986.

11   SCHEME AMENDMENTS AND TERMINATION

AMENDMENTS

(a)  Notwithstanding the provisions of Rules 11(b) to 11(f) and 12(b), the
     Directors may at any time make such alterations (including additions) to
     the Rules as are necessary to secure that the Rules receive initial
     approval from the Board of Inland Revenue under Schedule 9 and continue to
     be so approved.

(b)  Subject to Rule 11(d) and 11(e) the Directors may from time to time at
     their absolute discretion amend any of the Rules provided that after
     Flotation except with the prior approval of the shareholders of the Company
     in general meeting no amendment to the advantage of Option-holders (present
     or future) shall be made to the Rules relating to:-

(c)  No amendment waiver or replacement to or of this Scheme (or any Rule) shall
     be made to the extent to which it would have the effect of abrogating or
     altering adversely any of the subsisting rights of Option-holders except
     with such consent on their part as would be required by the provisions of

     account of any of the events mentioned in Rule 9, or to obtain or maintain

     regulations for the administration of this Scheme and to amend the terms or
     impose further conditions on the grant and exercise of Options to take
     account of overseas taxation, and securities or exchange control laws
     provided always that such regulations, terms and conditions shall not be
     inconsistent with the provisions of this Scheme and shall not cause any of
     the provisions of Schedule 9 relevant to this Scheme to cease to be
     satisfied.

     ordinary resolution or the Directors may at any time resolve that no

                         RULES OF THE GALEN HOLDINGS PLC
                    UNAPPROVED EXECUTIVE SHARE OPTION SCHEME

1    This Schedule to the Approved Executive Share Option Scheme ("the Scheme")

2    The Unapproved Scheme shall not be approved by the United Kingdom Board of
     Inland Revenue under Schedule 9 to the Act.

3    The Rules of the Scheme as from time to time amended shall be incorporated
     and form part of the rules of the Unapproved Scheme with the following
     modifications:-

     (a)  reference throughout the Scheme to the words "this Scheme" shall be
          taken as reference to "this Unapproved Scheme";

     (b)  adjustments under Rule 3(b) will not require the approval of the Board
          of Inland Revenue;

     (c)  Rules 4(a), 7(c), 11(d) in Rule 1(a) shall have no effect;.

     (d)  there shall be no requirement for the Scheme Shares to comply with
          paragraphs 10 to 14 inclusive of Schedule 9 to the Act;

     (e)  The definition of "Employee" in Rule 1(a) shall be deleted and the
          following substituted

          "Employee    A director (other than a non executive director) or a
                       bona fide employee of any company (whether he is taxed in
                       the United Kingdom or overseas) within the Group who, in
                       either case, is required to devote substantially the
                       whole of his working time to the business of the Group".

4    Where in relation to Options granted under the Unapproved Scheme the
     Company or a participating company is liable under any statute or
     regulation or otherwise to account to any revenue or other authority for
     sums in respect of tax or social security then the Company may impose such
     conditions upon the exercise of Options as are necessary or desirable to
     ensure that the requisite cash funds may be recovered from the
     Option-holder, including if necessary a condition that no exercise may take
     place unless the Company or a participating company has been provided by
     the Option-holder with cash funds sufficient to meet any liability for PAYE
     pursuant to section 203B of the Act or otherwise.

Borrowings may be repaid and reborrowed from time to time in accordance with the
terms and provisions of the Loan Documents; provided that, each such Borrowing
must occur on a Business Day and no later than the Business Day immediately
preceding the Revolver Maturity Date.

         (b) Loans under the Acquisition Subfacility shall be available to
Borrower for the purposes set forth in SECTION 6.12(b). After giving effect to
any Borrowing under the Acquisition Subfacility, the Acquisition Subfacility
Principal Debt shall not exceed the Acquisition Subfacility Commitment then in
effect.

         (c) Loans under the Working Capital/Distribution Subfacility shall be
available to Borrower for the purposes set forth in SECTION 6.12(c); provided,
however, Borrowings under the Working Capital/Distribution Subfacility will be
available to fund Quarterly Distributions only if, at the time of such Borrowing
and after giving effect thereto, there is at least $9,000,000.00 of the Working
Capital/Distribution Subfacility Commitment undrawn and available for working
capital purposes. After giving effect to any Borrowing under the Working
Capital/Distribution Subfacility, the Working Capital/Distribution Subfacility
Principal Debt shall not exceed the Working Capital/Distribution Subfacility
Commitment then in effect.

         2.02 TERM LOAN FACILITY. Subject to and in reliance upon the terms,
conditions, representations, and warranties in the Loan Documents, each Term
Loan Lender severally, but not jointly, agrees to lend to Borrower in a single
disbursement on the Conditions Effective Date such

                                       19
<PAGE>   25

Lender's Pro Rata Share of the Term Loan Commitment. If all or a portion of the
Term Loan Principal Debt is paid or prepaid, then the amount so paid or prepaid
may not be reborrowed. Any portion of the Term Loan Commitment that remains
undisbursed after the initial disbursement under the Term Loan Facility shall be
reduced to zero and cancelled on the date of such initial disbursement.

         2.03 BORROWINGS, CONVERSIONS AND CONTINUATIONS OF LOANS.

         (a) Each Borrowing, each conversion of Loans from one Type to the
other, and each continuation of Loans as the same Type shall be made upon the
Borrower's irrevocable notice to the Administrative Agent, which may be given by
telephone. Each such notice must be received by the Administrative Agent not
later than 11:00 a.m., New York time, (i) three Business Days prior to the
requested date of any Borrowing of, conversion to or continuation of Eurodollar
Rate Loans, (ii) one Business Day prior to the conversion of Eurodollar Rate
Loans to Base Rate Loans, and (iii) on the requested date of any Borrowing of
Base Rate Loans. Each such telephonic notice must be confirmed promptly by
delivery to the Administrative Agent of a written Borrowing Notice,
appropriately completed and signed by an Authorized Officer of the Borrower.
Each Borrowing of, conversion to or continuation of Eurodollar Rate Loans shall
be in a principal amount of $500,000 or a whole multiple of $500,000 in excess
thereof. Each Borrowing of or conversion to Base Rate Loans shall be in a
principal amount of $500,000 or a whole multiple of $100,000 in excess thereof.
Each Borrowing Notice (whether telephonic or written) shall specify (i) whether
the Borrowing, conversion or continuation (as applicable) is under the Term Loan
Facility or the Revolver Facility, and if it is under the Revolver Facility,
whether it is under the Acquisition Subfacility or the Working
Capital/Distribution Subfacility, (ii) whether the Borrower is requesting a
Borrowing, a conversion of Loans from one Type to the other, or a continuation
of Loans as the same Type, (iii) the requested date of the Borrowing, conversion
or continuation, as the case may be (which shall be a Business Day), (iv) the
principal amount of Loans to be borrowed, converted or continued, (v) the Type
of Loans to be borrowed or to which existing Loans are to be converted, and (vi)
if applicable, the duration of the Interest Period with respect thereto. If the
Borrower fails to specify a Type of Loan in a Borrowing Notice or if the
Borrower fails to give a timely notice requesting a conversion or continuation,
then the applicable Loans shall be made or continued as, or converted to, Base
Rate Loans. Any such automatic conversion to Base Rate Loans shall be effective
as of the last day of the Interest Period then in effect with respect to the
applicable Eurodollar Rate Loans. If the Borrower requests a Borrowing of,
conversion to, or continuation of Eurodollar Rate Loans in any such Borrowing
Notice, but fails to specify an Interest Period, it will be deemed to have
specified an Interest Period of one month.

         (b) Following receipt of a Borrowing Notice, the Administrative Agent
shall promptly notify each Lender of its Pro Rata Share of the applicable Loans,
and if no timely notice of a conversion or continuation is provided by the
Borrower, the Administrative Agent shall notify each Lender of the details of
any automatic conversion to Base Rate Loans described in the preceding
subsection. In the case of a Borrowing, each Lender shall make the amount of its
Loan available to the Administrative Agent in immediately available funds at the
Administrative Agent's Office not later than 1:00 p.m., New York time, on the
Business Day specified in the applicable Borrowing Notice. Upon satisfaction of
the applicable conditions set forth in SECTION 4.02 (and, if such Borrowing is
the initial Borrowing, SECTION 4.01), the Administrative Agent shall make all
funds so received available to the Borrower in like funds as received by the
Administrative Agent either by (i) crediting the account of the Borrower on the
books of Bank of America with the amount of such funds or (ii) wire transfer of
such funds, in each case in accordance with instructions provided to the
Administrative Agent by the Borrower.

         (c) Except as otherwise provided herein, a Eurodollar Rate Loan may be
continued or converted only on the last day of the Interest Period for such
Eurodollar Rate Loan. During the existence

                                       20
<PAGE>   26

of a Default or Event of Default, no Loans may be requested as, converted to or
continued as Eurodollar Rate Loans without the consent of the Required Lenders,
and the Required Lenders may demand that any or all of the then outstanding
Eurodollar Rate Loans be converted immediately to Base Rate Loans.

         (d) The Administrative Agent shall promptly notify the Borrower and the
Lenders of the interest rate applicable to any Eurodollar Rate Loan upon
determination of such interest rate. The determination of the Eurodollar Rate by
the Administrative Agent shall be conclusive in the absence of manifest error.

         (e) After giving effect to all Borrowings, all conversions of Loans
from one Type to the other, and all continuations of Loans as the same Type,
there shall not be more than ten (10) Interest Periods in effect at any given
time with respect to Loans.

         2.04 PREPAYMENTS.

         (a) Optional Prepayments. The Borrower may, upon notice to the
Administrative Agent, at any time or from time to time voluntarily prepay in
whole or in part the Acquisition Subfacility Principal Debt, the Working
Capital/Distribution Subfacility Principal Debt and/or the Term Loan Principal
Debt without premium or penalty; provided that (i) such notice must be received
by the Administrative Agent not later than 11:00 a.m., New York time, (A) three
Business Days prior to any date of prepayment of Eurodollar Rate Loans, and (B)
on the date of prepayment of Base Rate Loans; (ii) any prepayment of Eurodollar
Rate Loans shall be in a principal amount of $500,000 or a whole multiple of
$500,000 in excess thereof; and (iii) any prepayment of Base Rate Loans shall be
in a principal amount of $500,000 or a whole multiple of $100,000 in excess
thereof. Each such notice shall specify the date and amount of such prepayment,
the Facility (or, as the case may be, Subfacility) being prepaid and the Type(s)
of Loans to be prepaid. The Administrative Agent will promptly notify each
Lender of its receipt of each such notice, and of such Lender's Pro Rata Share
of such prepayment. If such notice is given by the Borrower, the Borrower shall
make such prepayment and the payment amount specified in such notice shall be
due and payable on the date specified therein. Any prepayment of a Eurodollar
Rate Loan shall be accompanied by all accrued interest thereon, together with
any additional amounts required pursuant to SECTION 3.05. Each such prepayment
shall be applied to the Loans of the Lenders in accordance with their respective
Pro Rata Shares.

         2.04(b)) by the Required Amount as defined in this SECTION 2.04(b)(i).
         As used in this Section: (A) "Outstanding Indebtedness" as of any date
         means the aggregate principal amount of outstanding Indebtedness plus
         the Attributable Principal of all Synthetic Leases of the Borrower and
         its Subsidiaries (including the Indebtedness being issued, incurred or
         assumed on such date but excluding Permitted Affiliate Subordinated

         such Net Cash Proceeds (including receipt of any deferred payments for
         any such Significant Sale or portion thereof, if and when received),
         then on the day following the ninetieth day after receipt of such Net
         Cash Proceeds, the Outstanding Amount shall be prepaid (and the

         2.04(b)), in the order and manner specified in the following paragraph,

         The commitment reductions or prepayments provided for under SECTIONS

in at least the amount of such excess, and (ii) if the Working

reduction of the Revolver Commitment shall be applied to the Commitment of each
Revolver Lender according to its Pro Rata Share, and any reduction of the Term
Loan Commitment shall be applied to the Commitment of each Term Loan Lender
according to its Pro Rata Share. All commitment fees on the portion of the

termination of Commitments shall be paid on the effective date of such
termination.

         2.06 REPAYMENT OF LOANS. The Borrower shall repay to the Revolver

Obligations at a fluctuating interest rate per annum at all times equal to the

and unpaid interest on past due amounts (including interest on past due

ending on the earlier of (i) the date of the initial Borrowing under the Term
Loan Facility or (ii) termination of the Term Loan Commitment, the Borrower
shall pay to the Administrative Agent for the account of each Term Loan Lender
in accordance with its Pro Rata Share, a commitment fee equal to the Applicable
Rate times the Term Loan Commitment. For the period commencing on the Closing
Date and ending on the Revolver Maturity Date, the Borrower shall pay to the
Administrative Agent for the account of each Revolver Lender in accordance with
its Pro Rata Share, a commitment fee equal to the Applicable Rate times the
actual daily amount by which the aggregate Revolver Commitment exceeds the
Revolver Principal Debt. The commitment fee shall accrue at all times from the
Closing Date, and shall be due and payable quarterly in arrears on the last
Business Day of each March, June, September and December, commencing with the
first such date to occur after the Closing Date, and on the Maturity Date. The
commitment fee shall be calculated quarterly in arrears, and if there is any
change in the Applicable Rate during any quarter, the actual daily amount shall
be computed and multiplied by the Applicable Rate separately for each period
during such quarter that such Applicable Rate was in effect. The commitment fee
shall accrue at all times, including at any time during which one or more of the
conditions in ARTICLE IV is not met.

         (b) Arrangement and Agency Fees. The Borrower shall pay an arrangement
fee to the Arrangers for the Arrangers' own account, and shall pay an agency fee
to the Administrative Agent for the Administrative Agent's own account, in the
amounts and at the times specified in the letter agreement, dated January 5,
2001 (the "AGENT/ARRANGER FEE LETTER"), between the Borrower, the Arrangers and
the Administrative Agent. Such fees shall be fully earned when paid and shall be
nonrefundable for any reason whatsoever.

         (c) Lenders' Upfront Fee. On the Initial Funding Date, the Borrower
shall pay to the Administrative Agent, for the account of the Lenders in
accordance with their respective Pro Rata Shares, an upfront fee in the agreed
amount in accordance with the Agent/Arranger Fee Letter. Such upfront fees are
for the credit facilities by the Lenders under this Agreement and are fully
earned on the date paid. The upfront fee paid to each Lender is solely for its
own account and is nonrefundable for any reason whatsoever.

         2.09 COMPUTATION OF INTEREST AND FEES. Computation of interest on Base
Rate Loans shall be calculated on the basis of a year of 365 or 366 days, as the
case may be, and the actual number of days elapsed. Computation of all other
types of interest and all fees shall be calculated on the basis of a year of 360
days and the actual number of days elapsed, which results in a higher yield to
the payee thereof than a method based on a year of 365 or 366 days. Interest
shall accrue on each Loan for the day on which the Loan is made, and shall not
accrue on a Loan, or any portion thereof, for the day on which the Loan or such
portion is paid, provided that any Loan that is repaid on the same day on which
it is made shall bear interest for one day.

         2.10 EVIDENCE OF DEBT. The Loans made by each Lender shall be evidenced
by one or more accounts or records maintained by such Lender and by the
Administrative Agent in the ordinary course of business. The accounts or records
maintained by the Administrative Agent and each Lender shall be conclusive
absent manifest error of the amount of the Loans made by the Lenders to the
Borrower and the interest and payments thereon. Any failure so to record or any
error in doing so shall not, however, limit or otherwise affect the obligation
of the Borrower hereunder to pay any amount owing with respect to the Loans. In
the event of any conflict between the accounts and records maintained by any
Lender and the accounts and records of the Administrative Agent in respect of
such matters, the accounts and

                                       24
<PAGE>   30

records of such Lender shall control. Upon the request of any Lender made
through the Administrative Agent, such Lender's Loans may be evidenced by one or
more of the following Notes (as the case may be): (i) a Revolver Note (with
respect to the Revolver Principal Debt), and (ii) a Term Note (with respect to
the Term Loan Principal Debt). Each Lender may attach schedules to its Note(s)
and endorse thereon the date, Type (if applicable), amount and maturity of the
applicable Loans and payments with respect thereto.

         2.11 PAYMENTS GENERALLY.

         (a) All payments to be made by the Borrower shall be made without
condition or deduction for any counterclaim, defense, recoupment or setoff.
Except as otherwise expressly provided herein, all payments by the Borrower
hereunder shall be made to the Administrative Agent, for the account of the
respective Lenders to which such payment is owed, at the Administrative Agent's
Office in Dollars and in immediately available funds not later than 12:00 noon,
New York time, on the date specified herein. The Administrative Agent will
promptly distribute to each Lender its Pro Rata Share (or other applicable share
as provided herein) of such payment in like funds as received by wire transfer
to such Lender's Lending Office. All payments received by the Administrative
Agent after 12:00 noon, New York time, shall be deemed received on the next
succeeding Business Day and any applicable interest or fee shall continue to
accrue.

         (b) Subject to the definition of "Interest Period," if any payment to
be made by the Borrower shall come due on a day other than a Business Day,
payment shall be made on the next following Business Day, and such extension of
time shall be reflected in computing interest or fees, as the case may be.

         (c) If at any time insufficient funds are received by and available to
the Administrative Agent to pay fully all amounts of principal, interest and
fees then due hereunder, such funds shall be applied (i) first, toward costs and
expenses (including Attorney Costs and amounts payable under ARTICLE III)
incurred by the Administrative Agent and each Lender, (ii) second, toward
repayment of interest and fees then due hereunder, ratably among the parties
entitled thereto in accordance with the amounts of interest and fees then due to
such parties, and (iii) third, toward repayment of principal then due hereunder,
ratably among the parties entitled thereto in accordance with the amounts of
principal then due to such parties.

         (d) Unless the Borrower or any Lender has notified the Administrative
Agent prior to the date any payment is required to be made by it to the
Administrative Agent hereunder, that the Borrower or such Lender, as the case
may be, will not make such payment, the Administrative Agent may assume that the
Borrower or such Lender, as the case may be, has timely made such payment and
may (but shall not be so required to), in reliance thereon, make available a
corresponding amount to the Person entitled thereto. If and to the extent that
such payment was not in fact made to the Administrative Agent in immediately
available funds, then:

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

                                       25
<PAGE>   31

                  (ii) if any Lender failed to make such payment, such Lender
         shall forthwith on demand pay to the Administrative Agent the amount
         thereof in immediately available funds, together with interest thereon
         for the period from the date such amount was made available by the
         Administrative Agent to the Borrower to the date such amount is
         recovered by the Administrative Agent (the "COMPENSATION PERIOD") at a
         rate per annum equal to the Federal Funds Rate from time to time in
         effect. If such Lender pays such amount to the Administrative Agent,
         then such amount shall constitute such Lender's Loan, included in the
         applicable Borrowing. If such Lender does not pay such amount forthwith
         upon the Administrative Agent's demand therefor, the Administrative
         Agent may make a demand therefor upon the Borrower, and the Borrower
         shall pay such amount to the Administrative Agent, together with
         interest thereon for the Compensation Period at a rate per annum equal
         to the rate of interest applicable to the applicable Borrowing. Nothing
         herein shall be deemed to relieve any Lender from its obligation to
         fulfill its Commitment or to prejudice any rights which the
         Administrative Agent or the Borrower may have against any Lender as a
         result of any default by such Lender hereunder.

         A notice of the Administrative Agent to any Lender with respect to any
amount owing under this subsection (d) shall be conclusive, absent manifest
error.

         (e) If any Lender makes available to the Administrative Agent funds for
any Loan to be made by such Lender as provided in the foregoing provisions of
this ARTICLE II, and the conditions to the applicable Borrowing set forth in
ARTICLE IV are not satisfied or waived in accordance with the terms hereof, the
Administrative Agent shall return such funds (in like funds as received from
such Lender) to such Lender, without interest.

         (f) The obligations of the Lenders hereunder to make Loans are several
and not joint. The failure of any Lender to make any Loan on any date required
hereunder shall not relieve any other Lender of its corresponding obligation to
do so on such date, and no Lender shall be responsible for the failure of any
other Lender to so make its Loan or purchase its participation.

         (g) Nothing herein shall be deemed to obligate any Lender to obtain the
funds for any Loan in any particular place or manner or to constitute a
representation by any Lender that it has obtained or will obtain the funds for
any Loan in any particular place or manner.

         2.12 SHARING OF PAYMENTS. If, other than as expressly provided
elsewhere herein, any Lender shall obtain on account of the Loans made by it,
any payment (whether voluntary, involuntary, through the exercise of any right
of set-off, or otherwise) in excess of its ratable share (or other share
contemplated hereunder) thereof, such Lender shall immediately (a) notify the
Administrative Agent of such fact, and (b) purchase from the other Lenders such
participations in the Loans made by them, as shall be necessary to cause such
purchasing Lender to share the excess payment in respect of such Loan or such
participations, as the case may be, pro rata with each of them; provided,
however, that if all or any portion of such excess payment is thereafter
recovered from the purchasing Lender, such purchase shall to that extent be
rescinded and each other Lender shall repay to the purchasing Lender the
purchase price paid therefor, together with an amount equal to such paying
Lender's ratable share (according to the proportion of (i) the amount of such
paying Lender's required repayment to (ii) the total amount so recovered from
the purchasing Lender) of any interest or other amount paid or payable by the
purchasing Lender in respect of the total amount so recovered. The Borrower
agrees that any Lender so purchasing a participation from another Lender may, to
the fullest extent permitted by law, exercise all its rights of payment
(including the right of set-off, but subject to SECTION 10.09) with respect to
such participation as fully as if such Lender were the direct creditor of the
Borrower in the amount of such participation. The Administrative Agent will keep
records (which shall be conclusive and binding in the absence of

                                       26
<PAGE>   32

manifest error) of participations purchased under this Section and will in each
case notify the Lenders following any such purchases or repayments. Each Lender
that purchases a participation pursuant to this Section shall from and after
such purchase have the right to give all notices, requests, demands, directions
and other communications under this Agreement with respect to the portion of the
Obligations purchased to the same extent as though the purchasing Lender were
the original owner of the Obligations purchased.

         2.13 ORDER OF APPLICATION.

         (a) No Default. If no Default or Event of Default exists and if no
order of application is otherwise specified in the Loan Documents, payments and
prepayments of the Obligations shall be applied first to fees, second to accrued
interest then due and payable on the Outstanding Amount, and then to the
remaining Obligations in the order and manner as Borrower may direct.

         (b) Default. If a Default or Event of Default exists (or if Borrower
fails to give directions as permitted under SECTION 2.13(a)), any payment or
prepayment (including proceeds from the exercise of any Rights) shall be applied
to the Obligations in the following order: (i) to the payment of enforcement
expenses incurred by the Administrative Agent, including Attorney Costs; (ii) to
the ratable payment of all other fees, expenses, and indemnities for which the
Administrative Agent or Lenders have not been paid or reimbursed in accordance
with the Loan Documents (as used in this SECTION 2.13(b)(II), a "RATABLE
PAYMENT" for any Lender or the Administrative Agent shall be, on any date of
determination, that proportion which the portion of the total fees, expenses,
and indemnities owed to such Lender or the Administrative Agent bears to the
total aggregate fees and indemnities owed to all Lenders and the Administrative
Agent on such date of determination); (iii) to the ratable payment of accrued
and unpaid interest on the Outstanding Amount (as used in this SECTION
2.13(b)(III), "RATABLE PAYMENT" means, for any Lender, on any date of
determination, that proportion which the accrued and unpaid interest on the
Outstanding Amount owed to such Lender bears to the total accrued and unpaid
interest on the Outstanding Amount owed to all Lenders); (iv) to the ratable
payment of the Outstanding Amount (as used in this SECTION 2.13(b)(IV), "RATABLE
PAYMENT" means for any Lender, on any date of determination, that proportion
which the Outstanding Amount owed to such Lender bears to the Outstanding Amount
owed to all Lenders); and (v) to the payment of the remaining Obligations, if
any, in the order and manner Required Lenders deem appropriate.

         Subject to the provisions of ARTICLE IX and provided that
Administrative Agent shall not in any event be bound to inquire into or to
determine the validity, scope, or priority of any interest or entitlement of any
Lender and may suspend all payments or seek appropriate relief (including,
without limitation, instructions from Required Lenders or an action in the
nature of interpleader) in the event of any doubt or dispute as to any
apportionment or distribution contemplated hereby, Administrative Agent shall
promptly distribute such amounts to each Lender in accordance with the Agreement
and the related Loan Documents.

                                  ARTICLE III.
                     TAXES, YIELD PROTECTION AND ILLEGALITY

         3.01 TAXES.

         (a) Any and all payments by the Borrower to or for the account of the
Administrative Agent or any Lender under any Loan Document shall be made free
and clear of and without deduction for any and all present or future taxes,
duties, levies, imposts, deductions, assessments, fees, withholdings or similar
charges, and all liabilities with respect thereto, excluding, in the case of the
Administrative Agent

                                       27
<PAGE>   33

and each Lender, taxes imposed on or measured by its net income, and franchise
taxes imposed on it (in lieu of net income taxes), by the jurisdiction (or any
political subdivision thereof) under the Laws of which the Administrative Agent
or such Lender, as the case may be, is organized or maintains its Lending Office
(all such non-excluded taxes, duties, levies, imposts, deductions, assessments,
fees, withholdings or similar charges, and liabilities being hereinafter
referred to as "TAXES"). If the Borrower shall be required by any Laws to deduct
any Taxes from or in respect of any sum payable under any Loan Document to the
Administrative Agent or any Lender, (i) the sum payable shall be increased as
necessary so that after making all required deductions (including deductions
applicable to additional sums payable under this Section), each of the
Administrative Agent and such Lender receives an amount equal to the sum it
would have received had no such deductions been made, (ii) the Borrower shall
make such deductions, (iii) the Borrower shall pay the full amount deducted to
the relevant taxation authority or other authority in accordance with applicable
Laws, and (iv) within 30 days after the date of such payment, the Borrower shall
furnish to the Administrative Agent (which shall forward the same to such
Lender) the original or a certified copy of a receipt evidencing payment
thereof.

         (b) In addition, the Borrower agrees to pay any and all present or
future stamp, court or documentary taxes and any other excise or property taxes
or charges or similar levies which arise from any payment made under any Loan
Document or from the execution, delivery, performance, enforcement or
registration of, or otherwise with respect to, any Loan Document (hereinafter
referred to as "OTHER TAXES").

         (c) If the Borrower shall be required to deduct or pay any Taxes or
Other Taxes from or in respect of any sum payable under any Loan Document to the
Administrative Agent or any Lender, the Borrower shall also pay to the
Administrative Agent (for the account of such Lender) or to such Lender, at the
time interest is paid, such additional amount that such Lender specifies as
necessary to preserve the after-tax yield (after factoring in all taxes,
including taxes imposed on or measured by net income) such Lender would have
received if such Taxes or Other Taxes had not been imposed.

         (d) The Borrower agrees to indemnify the Administrative Agent and each
Lender for (i) the full amount of Taxes and Other Taxes (including any Taxes or
Other Taxes imposed or asserted by any jurisdiction on amounts payable under
this Section) paid by the Administrative Agent and such Lender, (ii) amounts
payable under SECTION 3.01(c) and (iii) any liability (including penalties,
interest and expenses) arising therefrom or with respect thereto. Payment under
this subsection (d) shall be made within 30 days after the date the Lender or
the Administrative Agent makes a demand therefor.

         3.02 ILLEGALITY. If any Lender determines that any Law has made it
unlawful, or that any Governmental Authority has asserted that it is unlawful,
for any Lender or its applicable Lending Office to make, maintain or fund
Eurodollar Rate Loans, or materially restricts the authority of such Lender to
purchase or sell, or to take deposits of, Dollars in the applicable offshore
Dollar market, or to determine or charge interest rates based upon the
Eurodollar Rate, then, on notice thereof by such Lender to the Borrower through
the Administrative Agent, any obligation of such Lender to make or continue
Eurodollar Rate Loans or to convert Base Rate Loans to Eurodollar Rate Loans
shall be suspended until such Lender notifies the Administrative Agent and the
Borrower that the circumstances giving rise to such determination no longer
exist. Upon receipt of such notice, the Borrower shall, upon demand from such
Lender (with a copy to the Administrative Agent), prepay or, if applicable,
convert all Eurodollar Rate Loans of such Lender to Base Rate Loans, either on
the last day of the Interest Period thereof, if such Lender may lawfully
continue to maintain such Eurodollar Rate Loans to such day, or immediately, if
such Lender may not lawfully continue to maintain such Eurodollar Rate Loans.
Upon any such prepayment or conversion, the Borrower shall also pay interest on
the amount so prepaid or converted. Each Lender agrees to designate a different
Lending Office if such designation will avoid the need for

                                       28
<PAGE>   34

such notice and will not, in the reasonable judgment of such Lender, otherwise
be materially disadvantageous to such Lender.

         3.03 INABILITY TO DETERMINE RATES. If the Administrative Agent
determines in connection with any request for a Eurodollar Rate Loan or a
conversion to or continuation thereof that (a) Dollar deposits are not being
offered to banks in the applicable offshore Dollar market for the applicable
amount and Interest Period of such Eurodollar Rate Loan, (b) adequate and
reasonable means do not exist for determining the Eurodollar Rate for such
Eurodollar Rate Loan, or (c) the Eurodollar Rate for such Eurodollar Rate Loan
does not adequately and fairly reflect the cost to the Lenders of funding such
Eurodollar Rate Loan, the Administrative Agent will promptly notify the Borrower
and all Lenders. Thereafter, the obligation of the Lenders to make or maintain
Eurodollar Rate Loans shall be suspended until the Administrative Agent revokes
such notice. Upon receipt of such notice, the Borrower may revoke any pending
request for a Borrowing, conversion or continuation of Eurodollar Rate Loans or,
failing that, will be deemed to have converted such request into a request for a
Borrowing of Base Rate Loans in the amount specified therein.

         3.04 INCREASED COST AND REDUCED RETURN; CAPITAL ADEQUACY; RESERVES ON
EURODOLLAR RATE LOANS.

         (a) If any Lender determines that as a result of the introduction of or
any change in or in the interpretation of any Law, or such Lender's compliance
therewith, there shall be any increase in the cost to such Lender of agreeing to
make or making, funding or maintaining Eurodollar Rate Loans, or a reduction in
the amount received or receivable by such Lender in connection with any of the
foregoing (excluding for purposes of this subsection (a) any such increased
costs or reduction in amount resulting from (i) Taxes or Other Taxes (as to
which SECTION 3.01 shall govern), (ii) changes in the basis of taxation of
overall net income or overall gross income by the United States or any foreign
jurisdiction or any political subdivision of either thereof under the Laws of
which such Lender is organized or has its Lending Office, and (iii) reserve
requirements contemplated by SECTION 3.04(c) utilized, as to Eurodollar Rate
Loans, in the determination of the Eurodollar Rate), then from time to time upon
demand of such Lender (with a copy of such demand to the Administrative Agent),
the Borrower shall pay to such Lender such additional amounts as will compensate
such Lender for such increased cost or reduction. No Lender shall have the right
to recover such additional amounts for any period more than 90 days prior to the
date such Lender notified the Borrower thereof.

         (b) If any Lender determines that the introduction of any Law regarding
capital adequacy or any change therein or in the interpretation thereof, or
compliance by such Lender (or its Lending Office) therewith, has the effect of
reducing the rate of return on the capital of such Lender or any corporation
controlling such Lender as a consequence of such Lender's obligations hereunder
(taking into consideration its policies with respect to capital adequacy and
such Lender's desired return on capital), then from time to time upon demand of
such Lender (with a copy of such demand to the Administrative Agent), the
Borrower shall pay to such Lender such additional amounts as will compensate
such Lender for such reduction. No Lender shall have the right to recover such
additional amounts for any period more than 90 days prior to the date such
Lender notified the Borrower thereof.

         (c) The Borrower shall pay to each Lender, as long as such Lender shall
be required under regulations of the Board to maintain reserves with respect to
liabilities or assets consisting of or including Eurocurrency funds or deposits
(currently known as "Eurocurrency liabilities"), additional costs on the unpaid
principal amount of each Eurodollar Rate Loan equal to the actual costs of such
reserves allocated to such Loan by such Lender (as determined by such Lender in
good faith, which determination shall be conclusive), which shall be due and
payable on each date on which interest is

                                       29
<PAGE>   35

payable on such Loan, provided the Borrower shall have received at least 15
days' prior notice (with a copy to the Administrative Agent) of such additional
interest from such Lender. If a Lender fails to give notice 15 days prior to the
relevant Interest Payment Date, such additional interest shall be due and
payable 15 days from receipt of such notice.

         3.05 FUNDING LOSSES. Upon demand of any Lender (with a copy to the
Administrative Agent) from time to time, the Borrower shall promptly compensate
such Lender for and hold such Lender harmless from any loss, cost or expense
incurred by it as a result of:

         (a) any continuation, conversion, payment or prepayment of any Loan
other than a Base Rate Loan on a day other than the last day of the Interest
Period for such Loan (whether voluntary, mandatory, automatic, by reason of
acceleration, or otherwise); or

         (b) any failure by the Borrower (for a reason other than the failure of
such Lender to make a Loan) to prepay, borrow, continue or convert any Loan
other than a Base Rate Loan on the date or in the amount notified by the
Borrower.

For purposes of calculating amounts payable by the Borrower to the Lenders under
this SECTION 3.05, each Lender shall be deemed to have funded each Eurodollar
Rate Loan made by it at the Eurodollar Rate for such Loan by a matching deposit
or other borrowing in the applicable offshore Dollar interbank market for a
comparable amount and for a comparable period, whether or not such Eurodollar
Rate Loan was in fact so funded.

         3.06 MATTERS APPLICABLE TO ALL REQUESTS FOR COMPENSATION. A certificate
of the Administrative Agent or any Lender claiming compensation under this
ARTICLE III and setting forth the additional amount or amounts to be paid to it
hereunder shall be conclusive in the absence of manifest error. In determining
such amount, the Administrative Agent or such Lender may use any reasonable
averaging and attribution methods.

         3.07 SURVIVAL. All of the Borrower's obligations under this ARTICLE III
shall survive termination of the Commitments and payment in full of all the
other Obligations.

                                  ARTICLE IV.
                       CONDITIONS PRECEDENT TO BORROWINGS

to have a Material Adverse Effect.

disputes pending or, to the knowledge of the Borrower after due and diligent
investigation, overtly threatened or contemplated, at law, in equity, in

                                       33
<PAGE>   39

         5.07 NO DEFAULT. There is no failure of any Material Agreement to be in
effect, and there is no default by the Borrower or any of its Subsidiaries under
any Material Agreement, if such failure to remain in effect, or such default,
could reasonably be expected to have a Material Adverse Effect.

         5.08 OWNERSHIP OF PROPERTY; LIENS. The Borrower and each Subsidiary has
good and marketable title in fee simple to, or valid leasehold interests in, all
real property necessary or used in the ordinary conduct of its business, except
for such defects in title as would not, individually or in the aggregate, have a
Material Adverse Effect. As of the Conditions Effective Date, the property of
the Borrower and its Subsidiaries is subject to no Liens, other than Permitted
Liens.

         5.09 ENVIRONMENTAL COMPLIANCE. The Borrower and its Subsidiaries
conduct in the ordinary course of business a review of the effect of existing
Environmental Laws and claims alleging potential liability under or
responsibility for violation of any Environmental Law on their respective
businesses, operations and properties, and as a result thereof the Borrower has
reasonably concluded that (a) any such claims would not, individually or in the
aggregate, have a Material Adverse Effect, (b) there is no environmental

Substance, on any property owned, operated or used by the Borrower or any of its
Subsidiaries that could reasonably be expected to have a Material Adverse
Effect, and (c) there is no violation of or by the Borrower or any of its

Borrower and its Subsidiaries are insured with financially sound and reputable
insurance companies not Affiliates of the Borrower, in such amounts, with such
deductibles and covering such risks as are customarily carried by companies
engaged in similar businesses and owning similar properties in localities where
the Borrower or its Subsidiaries operate.

         5.11 TAXES. The Borrower and its Subsidiaries have filed all Federal,
state and other material tax returns and reports required to be filed, and have
paid all Federal, state and other material taxes, assessments, fees and other
governmental charges levied or imposed upon them or their properties, income or
assets otherwise due and payable, except those which are being contested in good
faith by appropriate proceedings and for which adequate reserves have been
provided in accordance with GAAP. There is no proposed tax assessment against
the Borrower or any Subsidiary that would, if made, have a Material Adverse
Effect.

         5.12 ERISA COMPLIANCE.

         (a) Each Plan is in compliance in all material respects with the
applicable provisions of ERISA, the Code and other Federal or state Laws except
to the extent that noncompliance could not reasonably be expected to have a
Material Adverse Effect. Each Plan that is intended to qualify under Section
401(a) of the Code has received a favorable determination letter from the IRS or
an application for such a letter is currently being processed by the IRS with
respect thereto and, to the best knowledge of the Borrower, nothing has occurred
which would prevent, or cause the loss of, such qualification. The Borrower and
each ERISA Affiliate have made all required contributions to each Plan subject
to Section 412 of the Code, and no application for a funding waiver or an
extension of any amortization period pursuant to Section 412 of the Code has
been made with respect to any Plan.

         (b) There are no pending or, to the best knowledge of the Borrower,
threatened claims, actions or lawsuits, or action by any Governmental Authority,
with respect to any Plan that could be reasonably be expected to have a Material
Adverse Effect. Neither the Borrower nor any ERISA

                                       34
<PAGE>   40

Affiliate has engaged in or knowingly permitted to occur and, to the Borrower's
knowledge, no other party has engaged in or permitted to occur any prohibited
transaction or violation of the fiduciary responsibility rules with respect to
any Plan that has resulted or could be reasonably expected to result in a
Material Adverse Effect.

         (c) (i) No ERISA Event has occurred or is reasonably expected to occur;
(ii) no Pension Plan has any Unfunded Pension Liability that (when aggregated
with any other Unfunded Pension Liability) has resulted or could reasonably be
expected to result in a Material Adverse Effect; (iii) neither the Borrower nor
any ERISA Affiliate has incurred, or reasonably expects to incur, any liability
under Title IV of ERISA with respect to any Pension Plan (other than premiums
due and not delinquent under Section 4007 of ERISA) which could reasonably be
expected to result in a Material Adverse Effect; (iv) neither the Borrower nor
any ERISA Affiliate has incurred, or reasonably expects to incur, any liability
(and no event has occurred which, with the giving of notice under Section 4219
of ERISA, would result in such liability) under Sections 4201 or 4243 of ERISA
with respect to a Multiemployer Plan which could reasonably be expected to
result in a Material Adverse Effect; and (v) neither the Borrower nor any ERISA
Affiliate has engaged in a transaction that could be subject to Sections 4069 or
4212(c) of ERISA.

         5.13 SUBSIDIARIES. As of the Closing Date the Borrower has no
Subsidiaries. As of the Initial Funding Date the Borrower will have no
Subsidiaries other than those specifically disclosed in SCHEDULE 5.13.

COMPANY ACT; USE OF PROCEEDS.

one of its important activities, in the business of purchasing or carrying
margin stock (within the meaning of Regulation U issued by the Board), or
extending credit for the purpose of purchasing or carrying margin stock. Margin
Stock constitutes less than 25% of those assets of the Loan Parties which are
subject to any limitation on a sale, pledge, or other restrictions hereunder.

         (b) None of the Borrower, any Person controlling the Borrower, or any
Subsidiary (i) is a "holding company," or a "subsidiary company" of a "holding
company," or an "affiliate" of a "holding company" or of a "subsidiary company"
of a "holding company," within the meaning of the Public Utility Holding Company
Act of 1935, or (ii) is or is required to be registered as an "investment
company" under the Investment Company Act of 1940.

         (c) The Borrower will use all proceeds of Borrowings in the manner set
forth in SECTION 6.12.

         5.15 DISCLOSURE. No statement, information, report, representation, or
warranty made by any Loan Party in any Loan Document or furnished to the
Administrative Agent or any Lender by or on behalf of any Loan Party in
connection with any Loan Document contains any untrue statement of a material
fact or omits any material fact required to be stated therein or necessary to
make the statements therein, in light of the circumstances under which they were
made, not misleading.

         5.16 LABOR MATTERS. To the Borrower's knowledge, there are no actual or
threatened strikes, labor disputes, slowdowns, walkouts, or other concerted
interruptions of operations by the employees of the Borrower or any of its
Subsidiaries that could reasonably be expected to have a Material Adverse
Effect. Hours worked by and payment made to employees of the Borrower or any of
its Subsidiaries have not been in violation of the Fair Labor Standards Act of
1938 or any other applicable Law dealing

                                       35
<PAGE>   41

with such matters, other than any such violations, individually or collectively,
which could not reasonably be expected to have a Material Adverse Effect. All
payments due from the Borrower or any of its Subsidiaries on account of employee
health and welfare insurance have been paid or accrued as a liability on its
books, other than any such nonpayments which could not, individually or
collectively, reasonably be expected to have a Material Adverse Effect.

         5.17 COMPLIANCE WITH LAWS. Neither the Borrower nor any of its
Subsidiaries are in violation of any Laws, other than such violations which
could not, individually or collectively, reasonably be expected to have a
Material Adverse Effect. Neither the Borrower nor any of its Subsidiaries has
received notice alleging any noncompliance with any Laws, except for such
noncompliance which no longer exists, or which non-compliance could not
reasonably be expected to have a Material Adverse Effect.

         Indebtedness in connection with such asset acquisition); and

                  (ii) If, in connection with an Asset Acquisition during any
         Reference Period, any Indebtedness (including Permitted Affiliate

                                  ARTICLE IX.
                              ADMINISTRATIVE AGENT

         9.01 APPOINTMENT AND AUTHORIZATION OF ADMINISTRATIVE AGENT. Each Lender
hereby irrevocably (subject to SECTION 9.09) appoints, designates and authorizes
the Administrative Agent to take such action on its behalf under the provisions
of this Agreement and each other Loan Document and to exercise such powers and
perform such duties as are expressly delegated to it by the terms of this
Agreement or any other Loan Document, together with such powers as are
reasonably incidental thereto. Notwithstanding any provision to the contrary
contained elsewhere herein or in any other Loan Document, the Administrative
Agent shall not have any duties or responsibilities, except those expressly set
forth herein, nor shall the Administrative Agent have or be deemed to have any
fiduciary relationship with any Lender or participant, and no implied covenants,
functions, responsibilities, duties, obligations or liabilities shall be read
into this Agreement or any other Loan Document or otherwise exist against the
Administrative Agent. Without limiting the generality of the foregoing sentence,
the use of the term "agent" herein and in the other Loan Documents with
reference to the Administrative Agent is not intended to connote any fiduciary
or other implied (or express) obligations arising under agency doctrine of any
applicable law. Instead, such term is used merely as a matter of market custom,
and is intended to create or reflect only an administrative relationship between
independent contracting parties.

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

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

         9.04 RELIANCE BY ADMINISTRATIVE AGENT.

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

         (b) For purposes of determining compliance with the conditions to the
initial Borrowing specified in SECTION 4.01, each Lender that has funded its Pro
Rata Share of the Borrowing(s) on the Initial Funding Date shall be deemed to
have consented to, approved or accepted or to be satisfied with, each document
or other matter either sent by the Administrative Agent to such Lender for
consent, approval, acceptance or satisfaction, or required hereunder to be
consented to or approved by or acceptable or satisfactory to a Lender.

         9.05 NOTICE OF DEFAULT. The Administrative Agent shall not be deemed to
have knowledge or notice of the occurrence of any Default or Event of Default,
except with respect to defaults in the payment of principal, interest and fees
required to be paid to the Administrative Agent for the account of the Lenders,
unless the Administrative Agent shall have received written notice from a Lender
or the Borrower referring to this Agreement, describing such Default or Event of
Default and stating that such notice is a "notice of default." The
Administrative Agent will notify the Lenders of its receipt of any such notice.
The Administrative Agent shall take such action with respect to such Default or
Event of Default as may be directed by the Required Lenders in accordance with
ARTICLE VIII; provided, however,

                                       47
<PAGE>   53

that unless and until the Administrative Agent has received any such direction,
the Administrative Agent may (but shall not be obligated to) take such action,
or refrain from taking such action, with respect to such Default or Event of
Default as it shall deem advisable or in the best interest of the Lenders.

         9.06 CREDIT DECISION; DISCLOSURE OF INFORMATION BY ADMINISTRATIVE
AGENT. Each Lender acknowledges that no Agent-Related Person has made any
representation or warranty to it, and that no act by the Administrative Agent
hereinafter taken, including any consent to and acceptance of any assignment or
review of the affairs of any Loan Party or any Affiliate thereof, shall be
deemed to constitute any representation or warranty by any Agent-Related Person
to any Lender as to any matter, including whether Agent-Related Persons have
disclosed material information in their possession. Each Lender represents to
the Administrative Agent that it has, independently and without reliance upon
any Agent-Related Person and based on such documents and information as it has
deemed appropriate, made its own appraisal of and investigation into the
business, prospects, operations, property, financial and other condition and
creditworthiness of the Loan Parties and their respective Subsidiaries, and all
applicable bank or other regulatory Laws relating to the transactions
contemplated hereby, and made its own decision to enter into this Agreement and
to extend credit to the Borrower hereunder. Each Lender also represents that it
will, independently and without reliance upon any Agent-Related Person and based
on such documents and information as it shall deem appropriate at the time,
continue to make its own credit analysis, appraisals and decisions in taking or
not taking action under this Agreement and the other Loan Documents, and to make
such investigations as it deems necessary to inform itself as to the business,
prospects, operations, property, financial and other condition and
creditworthiness of the Borrower and the other Loan Parties. Except for notices,
reports and other documents expressly required to be furnished to the Lenders by
the Administrative Agent herein, the Administrative Agent shall not have any
duty or responsibility to provide any Lender with any credit or other
information concerning the business, prospects, operations, property, financial
and other condition or creditworthiness of any of the Loan Parties or any of
their respective Affiliates which may come into the possession of any
Agent-Related Person.

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

         9.08 ADMINISTRATIVE AGENT IN ITS INDIVIDUAL CAPACITY. Bank of America
and its Affiliates may make loans to, accept deposits from, acquire equity
interests in and generally engage in any kind of banking, trust, financial
advisory, underwriting or other business with each of the Loan Parties and their

                                       48
<PAGE>   54

respective Affiliates as though Bank of America were not the Administrative
Agent hereunder and without notice to or consent of the Lenders. The Lenders
acknowledge that, pursuant to such activities, Bank of America or its Affiliates
may receive information regarding any Loan Party or its Affiliates (including
information that may be subject to confidentiality obligations in favor of such
Loan Party or such Affiliate) and acknowledge that the Administrative Agent
shall be under no obligation to provide such information to them. With respect
to its Loans, Bank of America shall have the same rights and powers under this
Agreement as any other Lender and may exercise such rights and powers as though
it were not the Administrative Agent, and the terms "Lender" and "Lenders"
include Bank of America in its individual capacity.

         9.09 SUCCESSOR ADMINISTRATIVE AGENT. The Administrative Agent may
resign as Administrative Agent upon 30 days' notice to the Lenders and the
Borrower. If the Administrative Agent resigns under this Agreement, the Required
Lenders shall appoint from among the Lenders a successor administrative agent
for the Lenders which successor administrative agent shall be consented to by
the Borrower at all times other than during the existence of an Event of Default
(which consent of the Borrower shall not be unreasonably withheld or delayed).
If no successor administrative agent is appointed prior to the effective date of
the resignation of the Administrative Agent, the Administrative Agent may
appoint, after consulting with the Lenders and the Borrower, a successor
administrative agent from among the Lenders. Upon the acceptance of its
appointment as successor administrative agent hereunder, such successor
administrative agent shall succeed to all the rights, powers and duties of the
retiring Administrative Agent and the term "ADMINISTRATIVE AGENT" shall mean
such successor administrative agent and the retiring Administrative Agent's
appointment, powers and duties as Administrative Agent shall be terminated.
After any retiring Administrative Agent's resignation hereunder as
Administrative Agent, the provisions of this ARTICLE IX and SECTIONS 10.03 and
10.13 shall inure to its benefit as to any actions taken or omitted to be taken
by it while it was Administrative Agent under this Agreement. If no successor
administrative agent has accepted appointment as Administrative Agent by the
date which is 30 days following a retiring Administrative Agent's notice of
resignation, the retiring Administrative Agent's resignation shall nevertheless
thereupon become effective and the Lenders shall perform all of the duties of
the Administrative Agent hereunder until such time, if any, as the Required
Lenders appoint a successor agent as provided for above.

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

                                   ARTICLE X.
                                  MISCELLANEOUS

         10.01 AMENDMENTS, ETC.

         (a) No amendment or waiver of any provision of this Agreement or any
other Loan Document, and no consent to any departure by the Borrower or any
other Loan Party therefrom, shall be effective unless in writing signed by the
Required Lenders and the Borrower or the applicable Loan Party, as the case may
be, and acknowledged by the Administrative Agent, and each such waiver or

                                       49
<PAGE>   55

consent shall be effective only in the specific instance and for the specific
purpose for which given; provided, however, that no such amendment, waiver or
consent shall, unless in writing and signed by each of the Lenders directly
affected thereby and by the Borrower, and acknowledged by the Administrative
Agent, do any of the following:

                  (i) extend or increase the Commitment of any Lender (or
         reinstate any Commitment terminated pursuant to SECTION 8.02);

                  (ii) postpone any date fixed by this Agreement or any other
         Loan Document for any payment or mandatory prepayment of principal,
         interest, fees or other amounts due to the Lenders (or any of them)
         hereunder or under any other Loan Document;

                  (iii) reduce the principal of, or the rate of interest
         specified herein on, any Loan or (subject to clause (B) of the proviso
         below) any fees or other amounts payable hereunder or under any other
         Loan Document, or change the manner of computation of any financial
         covenant used in determining the Applicable Rate that would result in a
         reduction of any interest rate on any Loan; provided, however, that
         only the consent of the Required Lenders shall be necessary to amend
         the definition of "Default Rate" or to waive any obligation of the
         Borrower to pay interest at the Default Rate; or

                  (iv) amend this Section, or SECTION 2.12, or any provision
         herein providing for unanimous consent or other action by all the
         Lenders;

and, provided further, that (A) no amendment, waiver or consent shall, unless in
writing and signed by the Administrative Agent in addition to the Required
Lenders or all the Lenders, as the case may be, affect the rights or duties of
the Administrative Agent under this Agreement or any other Loan Document; and
(B) the Agent/Arranger Fee Letter may be amended, or rights or privileges
thereunder waived, in a writing executed only by the parties thereto.
Notwithstanding anything to the contrary herein, any Lender that has failed to
fund any portion of the Loans required to be funded by it hereunder shall not
have any right to approve or disapprove any amendment, waiver or consent
hereunder, except that the Pro Rata Share of such Lender may not be increased
without the consent of such Lender.

         (b) Any amendment to any Loan Document which purports to (i) change the
allocation of payments between the Facilities, (ii) decrease the amount of any
mandatory prepayment or commitment reduction required by SECTION 2.04 or (iii)
change this SECTION 10.01(b), must be by an instrument in writing executed by
Borrower, the Administrative Agent and by (A) the Required Term Lenders and (B)
the Required Revolver Lenders.

         10.02 NOTICES AND OTHER COMMUNICATIONS; FACSIMILE COPIES.

         (a) General. Unless otherwise expressly provided herein, all notices
and other communications provided for hereunder and under the other Loan
Documents shall be in writing (including by facsimile transmission) and mailed,
faxed or delivered, to the address, facsimile number or (subject to subsection
(c) below) electronic mail address specified for notices on SCHEDULE 10.02 (for
the Borrower, each Guarantor and the Administrative Agent) or the signature
pages hereto (for the other Lenders); or, in the case of the Borrower, the
Guarantors or the Administrative Agent, to such other address as shall be
designated by such party in a notice to the other parties, and in the case of
any other party, to such other address as shall be designated by such party in a
notice to the Borrower and the Administrative Agent. All such notices and other
communications shall be deemed to be given or made

                                       50
<PAGE>   56

upon the earlier to occur of (i) actual receipt by the intended recipient and
(ii) (A) if delivered by hand or by courier, when signed for by the intended
recipient; (B) if delivered by mail, four Business Days after deposit in the
mails, postage prepaid; (C) if delivered by facsimile, when sent and receipt has
been confirmed by telephone; and (D) if delivered by electronic mail (which form
of delivery is subject to the provisions of subsection (c) below), when
delivered; provided, however, that notices and other communications to the
Administrative Agent pursuant to ARTICLE II shall not be effective until
actually received by such Person. Any notice or other communication permitted to
be given, made or confirmed by telephone hereunder shall be given, made or
confirmed by means of a telephone call to the intended recipient at the number
specified on SCHEDULE 10.02 or such Person's signature page, as applicable, it
being understood and agreed that a voicemail message shall in no event be
effective as a notice, communication or confirmation hereunder.

         (b) Effectiveness of Facsimile Documents and Signatures. Loan Documents
may be transmitted and/or signed by facsimile. The effectiveness of any such
documents and signatures shall, subject to applicable Law, have the same force
and effect as manually-signed originals and shall be binding on all Loan
Parties, the Administrative Agent and the Lenders. The Administrative Agent may
also require that any such documents and signatures be confirmed by a
manually-signed original thereof; provided, however, that the failure to request
or deliver the same shall not limit the effectiveness of any facsimile document
or signature.

         (c) Limited Use of Electronic Mail. Electronic mail and internet and
intranet websites may be used only to distribute routine communications, such as
financial statements and other information, and to distribute Loan Documents for
execution by the parties thereto, and may not be used for any other purpose.

         (d) Reliance by Administrative Agent and Lenders. The Administrative
Agent and the Lenders shall be entitled to rely and act upon any notices
(including telephonic Borrowing Notices) purportedly given by or on behalf of
the Borrower even if (i) such notices were not made in a manner specified
herein, were incomplete or were not preceded or followed by any other form of
notice specified herein, or (ii) the terms thereof, as understood by the
recipient, varied from any confirmation thereof. The Borrower shall indemnify
each Agent-Related Person and each Lender from all losses, costs, expenses and
liabilities resulting from the reliance by such Person on each notice
purportedly given by or on behalf of the Borrower. All telephonic notices to and
other communications with the Administrative Agent may be recorded by the
Administrative Agent, and each of the parties hereto hereby consents to such
recording.

         10.03 NO WAIVER; CUMULATIVE REMEDIES. No failure by any Lender or the
Administrative Agent to exercise, and no delay by any such Person in exercising,
any right, remedy, power or privilege hereunder shall operate as a waiver
thereof; nor shall any single or partial exercise of any right, remedy, power or
privilege hereunder preclude any other or further exercise thereof or the
exercise of any other right, remedy, power or privilege. The rights, remedies,
powers and privileges herein or therein provided are cumulative and not
exclusive of any rights, remedies, powers and privileges provided by law.

         10.04 ATTORNEY COSTS; EXPENSES AND TAXES. The Borrower agrees (a) to
pay or reimburse the Administrative Agent for all reasonable costs and expenses
incurred in connection with the preparation, negotiation, syndication,
administration and execution of this Agreement and the other Loan Documents and
any amendment, waiver, consent or other modification of the provisions hereof
and thereof (whether or not the transactions contemplated hereby or thereby are
consummated), and the consummation and administration of the transactions
contemplated hereby and thereby, including all Attorney Costs, and (b) to pay or
reimburse the Administrative Agent and each Lender for all costs and expenses
incurred in

                                       51
<PAGE>   57

connection with the enforcement, attempted enforcement, or preservation of any
rights or remedies under this Agreement or the other Loan Documents (including
all such costs and expenses incurred during any workout or restructuring in
respect of the Obligations and during any legal proceeding, including any
proceeding under any Debtor Relief Law), including all Attorney Costs. The
foregoing costs and expenses shall include all other out-of-pocket expenses
incurred by the Administrative Agent and the cost of independent public
accountants and other outside experts retained by the Administrative Agent or
any Lender. The agreements in this Section shall survive the termination of the
Commitments and repayment of all the other Obligations.

         10.05 INDEMNIFICATION. Whether or not the transactions contemplated
hereby are consummated, the Borrower and each Guarantor (by execution of a
Guaranty) agrees to indemnify, save and hold harmless each Agent-Related Person,
each Arranger, each Lender and their respective Affiliates, directors, officers,
employees, counsel, agents and attorneys-in-fact (collectively the
"Indemnitees") from and against: (a) any and all claims, demands, actions or
causes of action that are asserted against any Indemnitee by any Person (other
than the Administrative Agent or any Lender) relating directly or indirectly to
a claim, demand, action or cause of action that such Person asserts or may
assert against any Loan Party, any Affiliate of any Loan Party or any of their
respective officers or directors, arising out of or relating to, the Loan
Documents, the Commitments, the use or contemplated use of the proceeds of any
Loans, or the relationship of any Loan Party, the Administrative Agent and the
Lenders under this Agreement or any other Loan Document; (b) any and all claims,
demands, actions or causes of action that may at any time (including at any time
following repayment of the Obligations and the resignation of the Administrative
Agent or the replacement of any Lender) be asserted or imposed against any
Indemnitee, arising out of or relating to, the Loan Documents, the Commitments,
the use or contemplated use of the proceeds of any Loans, or the relationship of
any Loan Party, the Administrative Agent and the Lenders under this Agreement or
any other Loan Document; (c) without limiting the foregoing, any and all claims,
demands, actions or causes of action that are asserted or imposed against any
Indemnitee, (i) under the application of any Environmental Law applicable to the
Borrower or any of its Subsidiaries or any of their properties or assets,
including the treatment or disposal of Hazardous Substances on any of their
properties or assets, (ii) as a result of the breach or non-compliance by the
Borrower or any Subsidiary with any Environmental Law applicable to the Borrower
or any Subsidiary, (iii) due to past ownership by the Borrower or any Subsidiary
of any of their properties or assets or past activity on any of their properties
or assets which, though lawful and fully permissible at the time, could result
in present liability, (iv) due to the presence, use, storage, treatment or
disposal of Hazardous Substances on or under, or the escape, seepage, leakage,
spillage, discharge, emission or release from, any of the properties owned or
operated by the Borrower or any Subsidiary (including any liability asserted or
arising under any Environmental Law), regardless of whether caused by, or within
the control of, the Borrower or such Subsidiary, or (v) due to any other
environmental, health or safety condition in connection with the Loan Documents;
(d) any administrative or investigative proceeding by any Governmental Authority
arising out of or related to a claim, demand, action or cause of action
described in subsection (a), (b) or (c) above; and (e) any and all liabilities
(including liabilities under indemnities), losses, costs or expenses (including
Attorney Costs) that any Indemnitee suffers or incurs as a result of the
assertion of any foregoing claim, demand, action, cause of action or proceeding,
or as a result of the preparation of any defense in connection with any
foregoing claim, demand, action, cause of action or proceeding, in all cases,
WHETHER OR NOT ARISING OUT OF THE NEGLIGENCE OF AN INDEMNITEE, and whether or
not an Indemnitee is a party to such claim, demand, action, cause of action or
proceeding (all the foregoing, collectively, the "INDEMNIFIED LIABILITIES");
provided that no Indemnitee shall be entitled to indemnification for any claim
caused by its own gross negligence or willful misconduct. The agreements in this
Section shall survive the termination of the Commitments and repayment of all
the other Obligations.

                                       52
<PAGE>   58

         10.06 PAYMENTS SET ASIDE. To the extent that the Borrower makes a
payment to the Administrative Agent or any Lender, or the Administrative Agent
or any Lender exercises its right of set-off, and such payment or the proceeds
of such set-off or any part thereof is subsequently invalidated, declared to be
fraudulent or preferential, set aside or required (including pursuant to any
settlement entered into by the Administrative Agent or such Lender in its
discretion) to be repaid to a trustee, receiver or any other party, in
connection with any proceeding under any Debtor Relief Law or otherwise, then
(a) to the extent of such recovery, the obligation or part thereof originally
intended to be satisfied shall be revived and continued in full force and effect
as if such payment had not been made or such set-off had not occurred, and (b)
each Lender severally agrees to pay to the Administrative Agent upon demand its
applicable share of any amount so recovered from or repaid by the Administrative
Agent, plus interest thereon from the date of such demand to the date such
payment is made at a rate per annum equal to the Federal Funds Rate from time to
time in effect.

         10.07 SUCCESSORS AND ASSIGNS.

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

         (b) Any Lender may assign to one or more Eligible Assignees all or a
portion of its rights and obligations under this Agreement (including all or a
portion of its Commitment and the Loans at the time owing to it); provided that
(i) except in the case of an assignment of the entire remaining amount of the
assigning Lender's Commitment and the Loans at the time owing to it or in the
case of an assignment to a Lender or an Affiliate of a Lender, the aggregate
amount of the Commitment (which for this purpose includes Loans outstanding
thereunder) of the assigning Lender subject to each such assignment, determined
as of the date the Assignment and Acceptance with respect to such assignment is
delivered to the Administrative Agent, shall not be less than $1,000,000 in the
case of any assignment of a Revolver Commitment and Revolver Principal Debt, or
$5,000,000 in the case of any assignment of any Term Loan Principal Debt, unless
each of the Administrative Agent and, so long as no Event of Default has
occurred and is continuing, the Borrower otherwise consents (each such consent
not to be unreasonably withheld or delayed), (ii) each partial assignment shall
be made as an assignment of a proportionate part of all the assigning Lender's
rights and obligations under this Agreement with respect to the Loans or the
Commitment assigned, except that this clause (ii) shall not prohibit the
assignment of a proportionate part of all the assigning Lender's rights and
obligations in respect of one Facility, and (iii) the parties to each assignment
shall execute and deliver to the Administrative Agent an Assignment and
Acceptance, together with a processing and recordation fee of $3,500 (such fee
to be paid by the assignor or the assignee, as may be agreed between them). An
assignment need not be ratable as between the Term Loan Facility and the
Revolver Facility. Subject to acceptance and recording thereof by the
Administrative Agent pursuant to subsection (c) of this Section, from and after
the effective date specified in each Assignment and Acceptance, the Eligible
Assignee thereunder shall be a party hereto and, to the extent of the interest
assigned by such Assignment and Acceptance, have the rights and obligations of a
Lender under this Agreement, and the assigning Lender thereunder shall, to the
extent of the interest assigned by such Assignment and Acceptance, be released
from its obligations under this Agreement (and, in the case of an Assignment and
Acceptance covering all of the assigning Lender's rights and obligations under
this Agreement, such Lender shall cease to be a party hereto but shall continue
to be entitled to the benefits of

                                       53
<PAGE>   59

SECTIONS 3.07, 10.04 and 10.05). Upon request, the Borrower (at its expense)
shall execute and deliver new or replacement Notes to the assigning Lender and
the assignee Lender. Any assignment or transfer by a Lender of rights or
obligations under this Agreement that does not comply with this subsection shall
be treated for purposes of this Agreement as a sale by such Lender of a
participation in such rights and obligations in accordance with subsection (d)
of this Section.

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

         (d) Any Lender may, without the consent of, or notice to, the Borrower
or the Administrative Agent, sell participations to one or more banks or other
entities (a "PARTICIPANT") in all or a portion of such Lender's rights and/or
obligations under this Agreement (including all or a portion of its Commitment
and/or the Loans owing to it); provided that (i) such Lender's obligations under
this Agreement shall remain unchanged, (ii) such Lender shall remain solely
responsible to the other parties hereto for the performance of such obligations
and (iii) the Borrower, the Administrative Agent and the other Lenders shall
continue to deal solely and directly with such Lender in connection with such
Lender's rights and obligations under this Agreement. Any agreement or
instrument pursuant to which a Lender sells such a participation shall provide
that such Lender shall retain the sole right to enforce this Agreement and to
approve any amendment, modification or waiver of any provision of this
Agreement; provided that such agreement or instrument may provide that such
Lender will not, without the consent of the Participant, agree to any amendment,
waiver or other modification that would (i) postpone any date upon which any
payment of money is scheduled to be paid to such Participant, (ii) reduce the
principal, interest, fees or other amounts payable to such Participant, or (iii)
release any Guarantor from the Guaranty. Subject to subsection (e) of this
Section, the Borrower agrees that each Participant shall be entitled to the
benefits of SECTIONS 3.01, 3.04 and 3.05 to the same extent as if it were a
Lender and had acquired its interest by assignment pursuant to subsection (b) of
this Section. To the extent permitted by law, each Participant also shall be
entitled to the benefits of SECTION 10.09 as though it were a Lender, provided
such Participant agrees to be subject to SECTION 2.12 as though it were a
Lender.

         (e) A Participant shall not be entitled to receive any greater payment
under SECTION 3.01 or 3.04 than the applicable Lender would have been entitled
to receive with respect to the participation sold to such Participant, unless
the sale of the participation to such Participant is made with the Borrower's
prior written consent. A Participant that would be a Foreign Lender if it were a
Lender shall not be entitled to the benefits of SECTION 3.01 unless the Borrower
is notified of the participation sold to such Participant and such Participant
agrees, for the benefit of the Borrower, to comply with SECTION 10.15 as though
it were a Lender.

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

                                       54
<PAGE>   60

         (g) If the consent of the Borrower to an assignment or to an Eligible
Assignee is required hereunder (including a consent to an assignment which does
not meet the minimum assignment threshold specified in clause (i) of the proviso
to the first sentence of SECTION 10.07(b)), the Borrower shall be deemed to have
given its consent five Business Days after the date notice thereof has been
delivered by the assigning Lender (through the Administrative Agent) unless such
consent is expressly refused by the Borrower prior to such fifth Business Day.

         10.08 CONFIDENTIALITY. Each Lender agrees that it will not disclose
without the prior consent of the Borrower (other than to directors, officers,
employees, auditors, accountants, counsel or other professional advisors of the
Administrative Agent or any Lender) any information with respect to the Borrower
or its Subsidiaries, which is furnished pursuant to this Agreement and which (i)
the Borrower in good faith considers to be confidential and (ii) is either
clearly marked confidential or is designated by the Borrower to the
Administrative Agent or the Lenders in writing as confidential, provided that
any Lender may disclose any such information (a) as has become generally
available to the public, (b) as may be required or appropriate in any report,
statement or testimony submitted to or required by any municipal, state or
federal regulatory body having or claiming to have jurisdiction over such Lender
or submitted to or required by the Board or the Federal Deposit Insurance
Corporation or similar organizations (whether in the United States of America or
elsewhere) or their successors, (c) as may be required or appropriate in
response to any summons or subpoena in connection with any litigation, (d) in
order to comply with any law, order, regulation or ruling applicable to such
Lender, (e) to any Eligible Assignee of or Participant in, or any prospective
Eligible Assignee of or Participant in, any of its rights or obligations under
this Agreement, provided that such Eligible Assignee or Participant or
prospective Eligible Assignee or Participant executes an agreement containing
provisions substantially similar to those contained in this SECTION 10.08, (f)
in connection with the exercise of any remedy by such Lender following an Event
of Default pertaining to the Loan Documents, (g) in connection with any
litigation involving such Lender pertaining to the Loan Documents, (h) to any
Lender or the Administrative Agent, or (i) to any Affiliate of any Lender (it
being understood that the Persons to whom such disclosure is made will be
informed of the confidential nature of such information and instructed to keep
such information confidential).

         10.09 SET-OFF. In addition to any rights and remedies of the Lenders
provided by law, upon the occurrence and during the continuance of any Event of
Default, each Lender is authorized at any time and from time to time, without
prior notice to the Borrower or any other Loan Party, any such notice being
waived by the Borrower (on its own behalf and on behalf of each Loan Party) to
the fullest extent permitted by law, to set off and apply any and all deposits
(general or special, time or demand, provisional or final) at any time held by,
and other indebtedness at any time owing by, such Lender to or for the credit or
the account of the respective Loan Parties against any and all Obligations owing
to the Administrative Agent and the Lenders, now or hereafter existing,
irrespective of whether or not the Administrative Agent or such Lender shall
have made demand under this Agreement or any other Loan Document and although
such Obligations may be contingent or unmatured. Each Lender agrees promptly to
notify the Borrower and the Administrative Agent after any such set-off and
application made by such Lender; provided, however, that the failure to give
such notice shall not affect the validity of such set-off and application.

         10.10 INTEREST RATE LIMITATION. Regardless of any provision contained
in any Loan Document, neither the Administrative Agent nor any Lender shall ever
be entitled to contract for, charge, take, reserve, receive, or apply, as
interest on all or any part of the Obligations, any amount in excess of the
Maximum Rate, and, if any Lender ever does so, then such excess shall be deemed
a partial prepayment of principal and treated hereunder as such and any
remaining excess shall be refunded to the Borrower. In determining if the
interest paid or payable exceeds the Maximum Rate, the Borrower and

                                       55
<PAGE>   61

the Lenders shall, to the maximum extent permitted under applicable Law, (a)
treat all Borrowings as but a single extension of credit (and the Lenders and
the Borrower agree that such is the case and that provision herein for multiple
Borrowings is for convenience only), (b) characterize any nonprincipal payment
as an expense, fee, or premium rather than as interest, (c) exclude voluntary
prepayments and the effects thereof, and (d) amortize, prorate, allocate, and
spread the total amount of interest throughout the entire contemplated term of
the Obligations. However, if the Obligations are paid and performed in full
prior to the end of the full contemplated term thereof, and if the interest
received for the actual period of existence thereof exceeds the Maximum Amount,
the Lenders shall refund such excess, and, in such event, the Lenders shall not,
to the extent permitted by Law, be subject to any penalties provided by any Laws
for contracting for, charging, taking, reserving, or receiving interest in
excess of the Maximum Amount. If, contrary to the parties' intent expressed in
SECTION 10.16(a), the Laws of the State of Texas are applicable for purposes of
determining the "Maximum Rate" or the "Maximum Amount," then those terms mean
the "weekly ceiling" from time to time in effect under Texas Finance Code
Section 303.305, as amended. The Borrower agrees that Chapter 346 of the Texas
Finance Code, as amended (which regulates certain revolving credit loan accounts
and revolving tri-party accounts), does not apply to the Obligations.

         10.11 COUNTERPARTS. This Agreement may be executed in one or more
counterparts, each of which shall be deemed an original, but all of which
together shall constitute one and the same instrument.

         10.12 INTEGRATION. This Agreement, together with the other Loan
Documents, comprises the complete and integrated agreement of the parties on the
subject matter hereof and thereof and supersedes all prior agreements, written
or oral, on such subject matter. In the event of any conflict between the
provisions of this Agreement and those of any other Loan Document, the
provisions of this Agreement shall control; provided that the inclusion of
supplemental rights or remedies in favor of the Administrative Agent or the
Lenders in any other Loan Document shall not be deemed a conflict with this
Agreement. Each Loan Document was drafted with the joint participation of the
respective parties thereto and shall be construed neither against nor in favor
of any party, but rather in accordance with the fair meaning thereof.

         10.13 SURVIVAL OF REPRESENTATIONS AND WARRANTIES. All representations
and warranties made hereunder and in any other Loan Document or other document
delivered pursuant hereto or thereto or in connection herewith or therewith
shall survive the execution and delivery hereof and thereof. Such
representations and warranties have been or will be relied upon by the
Administrative Agent and each Lender, regardless of any investigation made by
the Administrative Agent or any Lender or on their behalf and notwithstanding
that the Administrative Agent or any Lender may have had notice or knowledge of
any Default or Event of Default at the time of any Borrowing, and shall continue
in full force and effect as long as any Loan or any other Obligation shall
remain unpaid or unsatisfied.

         10.14 SEVERABILITY. Any provision of this Agreement and the other Loan
Documents to which the Borrower is a party that is prohibited or unenforceable
in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent
of such prohibition or unenforceability without invalidating the remaining
provisions thereof, and any such prohibition or unenforceability in any
jurisdiction shall not invalidate or render unenforceable such provision in any
other jurisdiction.

         10.15 FOREIGN LENDERS. Each Lender that is a "foreign corporation,
partnership or trust" within the meaning of the Code (a "FOREIGN LENDER") shall
deliver to the Administrative Agent, prior to receipt of any payment subject to
withholding under the Code (or after accepting an assignment of an interest
herein), two duly signed completed copies of either IRS Form W-8BEN or any
successor thereto (relating to such Person and entitling it to an exemption
from, or reduction of, withholding tax on all

                                       56
<PAGE>   62

payments to be made to such Person by the Borrower pursuant to this Agreement)
or IRS Form W-8ECI or any successor thereto (relating to all payments to be made
to such Person by the Borrower pursuant to this Agreement) or such other
evidence satisfactory to the Borrower and the Administrative Agent that such
Person is entitled to an exemption from, or reduction of, U.S. withholding tax.
Thereafter and from time to time, each such Person shall (a) promptly submit to
the Administrative Agent such additional duly completed and signed copies of one
of such forms (or such successor forms as shall be adopted from time to time by
the relevant United States taxing authorities) as may then be available under
then current United States laws and regulations to avoid, or such evidence as is
satisfactory to the Borrower and the Administrative Agent of any available
exemption from or reduction of, United States withholding taxes in respect of
all payments to be made to such Person by the Borrower pursuant to this
Agreement, (b) promptly notify the Agent of any change in circumstances which
would modify or render invalid any claimed exemption or reduction, and (c) take
such steps as shall not be materially disadvantageous to it, in the reasonable
judgment of such Lender, and as may be reasonably necessary (including the
re-designation of its Lending Office) to avoid any requirement of applicable
Laws that the Borrower make any deduction or withholding for taxes from amounts
payable to such Person. If such Person fails to deliver the above forms or other
documentation, then the Administrative Agent may withhold from any interest
payment to such Person an amount equivalent to the applicable withholding tax
imposed by Sections 1441 and 1442 of the Code, without reduction. If any
Governmental Authority asserts that the Administrative Agent did not properly
withhold any tax or other amount from payments made in respect of such Person,
such Person shall indemnify the Administrative Agent therefor, including all
penalties and interest, any taxes imposed by any jurisdiction on the amounts
payable to the Agent under this Section, and costs and expenses (including
Attorney Costs) of the Administrative Agent. The obligation of the Lenders under
this Section shall survive the payment of all Obligations and the resignation or
replacement of the Administrative Agent.

         10.16 GOVERNING LAW.

         (a) THIS AGREEMENT SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE
WITH, the LAW OF THE STATE OF NEW YORK applicable to agreements made and to be
performed entirely within such State; PROVIDED THAT THE ADMINISTRATIVE Agent AND
EACH LENDER SHALL RETAIN ALL RIGHTS ARISING UNDER FEDERAL LAW.

         (b) EACH COMPANY AND OTHER PARTY HERETO, AND EACH GUARANTOR, BY
EXECUTION OF A GUARANTY, AGREES AS TO THIS SECTION 10.16(b). ANY LEGAL ACTION OR
PROCEEDING WITH RESPECT TO THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT MAY BE
BROUGHT IN THE COURTS OF THE STATE OF NEW YORK SITTING IN THE BOROUGH OF
MANHATTAN OR OF THE UNITED STATES FOR THE SOUTHERN DISTRICT OF SUCH STATE, AND
BY EXECUTION AND DELIVERY OF THIS AGREEMENT, THE BORROWER, THE ADMINISTRATIVE
Agent AND EACH LENDER CONSENTS, AND BY EXECUTION OF A GUARANTY, EACH GUARANTOR
CONSENTS, FOR ITSELF AND IN RESPECT OF ITS PROPERTY, TO THE NON-EXCLUSIVE
JURISDICTION OF THOSE COURTS. THE BORROWER, EACH GUARANTOR, THE ADMINISTRATIVE
Agent AND EACH LENDER (1) IRREVOCABLY WAIVES ANY OBJECTION, INCLUDING ANY
OBJECTION TO THE LAYING OF VENUE OR BASED ON THE GROUNDS OF FORUM NON
CONVENIENS, WHICH IT MAY NOW OR HEREAFTER HAVE TO THE BRINGING OF ANY ACTION OR
PROCEEDING IN SUCH JURISDICTION IN RESPECT OF ANY LOAN DOCUMENT OR OTHER
DOCUMENT RELATED THERETO, AND (2) IRREVOCABLY CONSENTS TO THE SERVICE OF PROCESS
OUT OF ANY OF THE AFOREMENTIONED COURTS IN ANY SUCH ACTION OR PROCEEDING BY THE
MAILING OF COPIES THEREOF BY CERTIFIED MAIL, RETURN RECEIPT

                                       57

REQUESTED, POSTAGE PREPAID, AT ITS ADDRESS FOR NOTICES DESIGNATED HEREIN. THE
BORROWER, EACH GUARANTOR, THE ADMINISTRATIVE Agent AND EACH LENDER WAIVES
PERSONAL SERVICE OF ANY SUMMONS, COMPLAINT OR OTHER PROCESS, WHICH MAY BE MADE
BY ANY OTHER MEANS PERMITTED BY THE LAW OF SUCH STATE. THE BORROWER AND EACH
GUARANTOR, BY ITS EXECUTION OF A GUARANTY, AGREES TO DESIGNATE AND MAINTAIN AN
AGENT FOR SERVICE OF PROCESS IN NEW YORK IN CONNECTION WITH ACTIONS AND
PROCEEDINGS UNDER THE LOAN DOCUMENTS AND TO DELIVER TO THE ADMINISTRATIVE AGENT
EVIDENCE THEREOF.

         10.17 WAIVER OF RIGHT TO TRIAL BY JURY. EACH PARTY TO THIS AGREEMENT
AND EACH GUARANTOR, BY EXECUTION OF A GUARANTY, HEREBY EXPRESSLY WAIVES ANY
RIGHT TO TRIAL BY JURY OF ANY CLAIM, DEMAND, ACTION OR CAUSE OF ACTION ARISING
UNDER ANY LOAN DOCUMENT OR IN ANY WAY CONNECTED WITH OR RELATED OR INCIDENTAL TO
THE DEALINGS OF THE PARTIES TO THE LOAN DOCUMENTS OR ANY OF THEM WITH RESPECT TO
ANY LOAN DOCUMENT, OR THE TRANSACTIONS RELATED THERETO, IN EACH CASE WHETHER NOW
EXISTING OR HEREAFTER ARISING, AND WHETHER FOUNDED IN CONTRACT OR TORT OR
OTHERWISE; AND EACH PARTY HEREBY AGREES AND CONSENTS THAT ANY SUCH CLAIM,
DEMAND, ACTION OR CAUSE OF ACTION SHALL BE DECIDED BY COURT TRIAL WITHOUT A
JURY, AND THAT ANY PARTY TO THIS AGREEMENT MAY FILE AN ORIGINAL COUNTERPART OR A
COPY OF THIS SECTION WITH ANY COURT AS WRITTEN EVIDENCE OF THE CONSENT OF THE
COMPANIES TO THE WAIVER OF THEIR RIGHT TO TRIAL BY JURY.

         10.18 NO GENERAL PARTNER'S LIABILITY. The Lenders agree for themselves
and their respective successors and assigns, including any subsequent holder of
any Note, that any claim against the Borrower which may arise under any Loan
Document shall be made only against and shall be limited to the assets of the
Borrower and the Guarantors, and that no judgment, order or execution entered in
any suit, action or proceeding, whether legal or equitable, on this Agreement,
such Note or any of the other Loan Documents shall be obtained or enforced
against the General Partner or its assets for the purpose of obtaining
satisfaction and payment of such Note, the Indebtedness evidenced thereby or any
claims arising thereunder or under this Agreement or any other Loan Document,
any right to proceed against the General Partner individually or its respective
assets being hereby expressly waived, renounced and remitted by the Lenders for
themselves and their respective successors and assigns. Nothing in this SECTION
10.18, however, shall be construed so as to prevent the Administrative Agent,
any Lender or any other holder of any Note from commencing any action, suit or
proceeding with respect to or causing legal papers to be served upon the General
Partner for the purpose of obtaining jurisdiction over Borrower.

         10.19 ENTIRE AGREEMENT. This Agreement and the other Loan Documents
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.
