                     specified benefit provided under this Plan, but having the

                            (4) four Years of Participation for any reason other
                            than Cause.

          4.2 Amount of Benefits. The benefit payable to the Participant or the
Participant's Beneficiary under the Plan shall be determined as follows:

                     (a)    Normal Retirement or Late Retirement. A monthly
                            benefit equal to the Participant's Accrued Benefit
                            commencing on the first day of the month following
                            the Participant's Determination Date.

                     (b)    Early Retirement. A monthly benefit equal to the

                            first day of the month coinciding with or next
                            following the Participant's sixtieth (60th)
                            birthday. Alternatively, the Participant may, no

                            Determination Date, elect to receive reduced monthly

                            month after the Participant's Determination Date.
                            The reduced benefit is equal to the Participant's
                            Accrued Benefit reduced by 4% for each year
                            (pro-rated for partial years) between the date of
                            the Participant's first benefit payment and the
                            first month coinciding with or next following the
                            Participant's sixtieth (60th) birthday.

                            commencing on the first (1st) day of the month
                            coinciding with or next following the

                           would have at age sixty (60) and the Participant's
                           Final Average Compensation at the time of the

                           and Permanent Disability. Such benefit shall be
                           reduced by any benefit the Participant receives from
                           the long term disability plan provided by the
                           Company.

                     (e)    Termination. A monthly benefit equal to the
                            Participant's Accrued Benefit commencing on the
                            first (1st) day of the month coinciding with or next
                            following the Participant's sixtieth (60th)
                            birthday.

                            Participant's Beneficiary for the balance of such
                            one hundred twenty (120) month period.

                     (c)    Monthly payments to the Participant or the

          5.1 Funding. All amounts paid under the Plan shall be paid in cash
from the general assets of the Company or in such form from such other funding
vehicle as the Board of Directors shall provide; provided, however, that all
assets paid into any funding vehicle hereunder shall at all times prior to

contained in the Plan and no action taken pursuant to its provisions, shall
create or be construed to create a trust or a fiduciary relationship of any kind
between the Company and the Participant or any other person. Neither the

greater than that of an unsecured creditor in any assets of the Company or in
any investment reserves, accounts, or funds that the Company may purchase,
establish or accumulate for the purposes of paying benefits hereunder.

          5.2 Continued Employment. Nothing contained in the Plan shall be

persons to whom they are payable. The interest of any Participant or his
Beneficiary may not be sold, transferred, assigned, or encumbered in any manner,
either voluntarily or involuntarily, and any attempt to so anticipate, alienate,
sell, transfer, assign, pledge, encumber, or charge the same shall be null and
void; neither shall the benefits hereunder be liable for or subject to the
debts, contracts, liabilities, engagements, or torts of any person to whom such
benefits or funds are payable, nor shall they be subject to garnishment,
attachment, or other legal equitable process nor shall they be an asset in
bankruptcy.

          5.4 Binding on Company, Participants and Their Successors. The Plan
shall be binding upon the parties hereto, the successors and assigns of the
Company and the heirs, executors and administrators of the Participants.

         Section 2.2 Revolving Loans.

                  (a) Amounts. Subject to the satisfaction of the conditions
         precedent set forth in Article 10, each Lender severally, but not

         Business Day during the period from the Closing Date to the Termination
         Date, to make revolving loans (the "Revolving Loans") to the Borrowers
         in amounts not to exceed (except for the Bank with respect to
         Non-Ratable Loans or for the Agent with respect to Agent Advances) such
         Lender's Pro Rata Share of the Borrowing Base. The Lenders, however, in
         their unanimous discretion, may elect to make Revolving Loans or issue
         or arrange to have issued Letters of Credit in excess of the
         Availability on one or more occasions, but if they do so, neither the
         Agent nor the Lenders shall be deemed thereby to have changed the
         limits of the Borrowing Base or to be obligated to exceed such limits
         on any other occasion. If the Aggregate Revolver Outstandings exceed
         the Borrowing Base, the Lenders may refuse to make or otherwise
         restrict the making of Revolving Loans as the Lenders determine until
         such excess has been eliminated, subject to the Agent's authority, in
         its sole discretion, to make Agent Advances pursuant to the terms of
         Section 2.2(i).

                  irrevocable written notice delivered to the Agent in the form
                  of a notice of borrowing (a "Notice of Borrowing") which must
                  be received by the Agent prior to 11:00 a.m. (Dallas, Texas

                  Funding Date, in the case of LIBOR Rate Loans and (z) no later
                  than 11:00 a.m. on the requested Funding Date, in the case of
                  Base Rate Loans, specifying:

                                             if a LIBOR Revolving Loan, shall be
                                             in an amount that is not less than
                                             $500,000 or that is in an integral

                                             thereof);

                                    (B)      the requested Funding Date, which
                                             shall be a Business Day;

                                    (C)      whether the Revolving Loans
                                             requested are to be Base Rate

                                             Loans; and

                                             are to be LIBOR Revolving Loans. If
                                             the Notice of Borrowing fails to
                                             specify the duration of the
                                             Interest Period for any Borrowing
                                             comprised of LIBOR Rate Loans, such
                                             Interest Period shall be one month;

                  provided, however, that with respect to any Borrowing to be
                  made on the Closing Date (if any), such Borrowing will consist
                  of Base Rate Revolving Loans.

                           (ii) With respect to any request for Base Rate
                  Revolving Loans, in lieu of delivering the above-described
                  Notice of Borrowing a Borrower may give the Agent

LOAN AND SECURITY AGREEMENT - Page 33

<PAGE>   41

                  telephonic notice of such request by the required time, with
                  such telephonic notice to be confirmed in writing within 24
                  hours of the giving of such notice but the Agent shall be
                  entitled to rely on the telephonic notice in making such
                  Revolving Loans.

                  (c) Reliance upon Authority. On or prior to the Closing Date
         and thereafter prior to any change with respect to any of the
         information contained in the following clauses (i) and (ii), the
         Borrowers shall deliver to the Agent a writing setting forth (i) the
         account of the Borrowers to which the Agent is authorized to transfer
         the proceeds of the Revolving Loans requested pursuant to this Section
         2.2, and (ii) the names of the individuals authorized to request
         Revolving Loans on behalf of each Borrower, and shall provide the Agent
         with a specimen signature of each such individual. The Agent shall be
         entitled to rely conclusively on any such individual's authority to
         request Revolving Loans on behalf of a Borrower, the proceeds of which
         are to be transferred to the account specified by the Borrowers
         pursuant to the immediately preceding sentence or disbursed in such
         other manner as such individual requesting such Borrowing may direct to
         the Agent, until the Agent receives written notice to the contrary. The
         Agent shall have no duty to verify the identity of any individual
         representing him or herself as one of the officers authorized by any
         Borrower to make such requests on its behalf. Each Borrower, as to
         itself, hereby irrevocably appoints each other Borrower as its
         attorney, with power to make withdrawals and transfers from, and
         deliver to the Agent instructions in respect of, the account of the
         Borrowers referenced in clause (i) preceding, and hereby irrevocably
         authorizes the Agent to rely upon the acts and instructions of each
         such other Borrower in accordance with the authority delegated pursuant
         to this sentence.

                  (d) No Liability. The Agent shall not incur any liability to
         the Loan Parties as a result of acting upon any notice referred to in
         Sections 2.2(b) and (c), which notice the Agent believes in good faith
         to have been given by an officer duly authorized by a Borrower to
         request Revolving Loans on its behalf or for otherwise acting in good
         faith under this Section 2.2, and the crediting of Revolving Loans to
         the Borrower's deposit account, or transmittal to such Person as the
         Borrower shall direct, shall conclusively establish the obligation of
         the Borrowers to repay such Revolving Loans as provided herein.

                  (e) Notice Irrevocable. Any Notice of Borrowing (or telephonic
         notice in lieu thereof) made pursuant to Section 2.2(b) shall be
         irrevocable and the Borrowers shall be bound to borrow the funds
         requested therein in accordance therewith.

                  (f) The Agent's Election. Promptly after receipt of a Notice
         of Borrowing (or telephonic notice in lieu thereof) pursuant to Section
         2.2(b), the Agent shall elect, in its discretion, (i) to have the terms
         of Section 2.2(g) apply to such requested Borrowing, or (ii) to request
         the Bank to make a Non-Ratable Loan pursuant to the terms of Section
         2.2(h) in the amount of the requested Borrowing; provided, however,
         that if the Bank declines in its sole discretion to make a Non-Ratable
         Loan pursuant to Section 2.2(h), the Agent shall elect to have the
         terms of Section 2.2(g) apply to such requested Borrowing.

                           (i) In the event that the Agent shall elect to have
                  the terms of this Section 2.2(g) apply to a requested
                  Borrowing as described in Section 2.2(f), then promptly after
                  receipt of a Notice of Borrowing or telephonic notice pursuant
                  to Section 2.2(b), the Agent shall notify the Lenders by
                  telecopy, telephone or other similar form of transmission, of
                  the requested Borrowing. Each Lender shall make the amount of
                  such Lender's Pro Rata Share of the requested Borrowing
                  available to the Agent in immediate available funds, to such
                  account of the Agent as the Agent may designate, not later
                  than 2:00 p.m., (Dallas, Texas time) on the Funding Date
                  applicable thereto. After the Agent's receipt of the proceeds
                  of such Revolving Loans, upon satisfaction of the applicable
                  conditions precedent set forth in Article 10, the Agent shall
                  make the proceeds of such Revolving Loans available on the
                  applicable Funding Date by transferring same day funds equal
                  to the proceeds of such Revolving Loans received by the Agent
                  to the account designated pursuant to clause (i) of Section
                  2.2(c) or disbursing such funds in such other manner as the
                  Borrower requesting such Borrowing may direct to the Agent;
                  provided, however, that the amount of Revolving Loans so made
                  on any date shall in no event result in Availability of less
                  than zero Dollars ($0).

                           (ii) Unless the Agent receives notice from a Lender
                  on or prior to the Closing Date or, with respect to any
                  Borrowing after the Closing Date, at least one Business Day
                  prior to the date of such Borrowing, that such Lender will not
                  make available as and when required hereunder to the Agent for
                  the account of the Borrowers the amount of that Lender's Pro
                  Rata Share of the Borrowing, the Agent may assume that each
                  Lender has made such amount available to the Agent in
                  immediately available funds on the Funding Date and the Agent
                  may (but shall not be so required), in reliance upon such
                  assumption, make available to the Borrower on such date a
                  corresponding amount. If and to the extent any Lender shall
                  not have made its full amount available to the Agent in
                  immediately available funds and the Agent in such
                  circumstances has made available to the Borrower such amount,
                  that Lender shall on the Business Day following such Funding
                  Date make such amount available to the Agent, together with
                  interest at the Federal Funds Rate for each day during such
                  period. A notice by the Agent submitted to any Lender with
                  respect to amounts owing under this subsection shall be
                  conclusive, absent manifest error. If such amount is so made
                  available, such payment to the Agent shall constitute such
                  Lender's Revolving Loan for all purposes of this Agreement. If
                  such amount is not made available to the Agent on the Business
                  Day following the Funding Date, the Agent will notify the
                  Borrower of such failure to fund and, upon demand by the
                  Agent, the Borrower shall pay such amount to the Agent for the
                  Agent's account, together with interest thereon for each day
                  elapsed since the date of such Borrowing, at a rate per annum
                  equal to the Interest Rate applicable at the time to the
                  Revolving Loans comprising such Borrowing. The failure of any
                  Lender to make any Revolving Loan on any Funding Date (any
                  such Lender, prior to the cure of such failure, being
                  hereinafter referred to as a "Defaulting Lender") shall not
                  relieve any other Lender of

LOAN AND SECURITY AGREEMENT - Page 35

<PAGE>   43

                  any obligation hereunder to make a Revolving Loan on such
                  Funding Date, but no Lender shall be responsible for the
                  failure of any other Lender to make the Revolving Loan to be
                  made by such other Lender on any Funding Date.

                           (iii) The Agent shall not be obligated to transfer to
                  a Defaulting Lender any payments made by any Borrower to the
                  Agent for the Defaulting Lender's benefit; nor shall a
                  Defaulting Lender be entitled to the sharing of any payments
                  hereunder. Amounts payable to a Defaulting Lender shall
                  instead be paid to or retained by the Agent. The Agent may
                  hold and, in its discretion, re-lend to any Borrower the
                  amount of all such payments received or retained by it for the
                  account of such Defaulting Lender. Any amounts so re-lent to a
                  Borrower shall bear interest at the rate applicable to Base
                  Rate Revolving Loans and for all other purposes of this
                  Agreement shall be treated as if they were Revolving Loans,
                  provided, however, that for purposes of voting or consenting
                  to matters with respect to the Loan Documents and determining
                  Pro Rata Shares, such Defaulting Lender shall be deemed not to
                  be a "Lender". Until a Defaulting Lender cures its failure to
                  fund its Pro Rata Share of any Borrowing (A) such Defaulting
                  Lender shall not be entitled to any portion of the Unused Line
                  Fee and (B) the Unused Line Fee shall accrue in favor of the
                  Lenders which have funded their respective Pro Rata Shares of
                  such requested Borrowing and shall be allocated among such
                  performing Lenders ratably based upon their relative
                  Commitments. This Section shall remain effective with respect
                  to such Lender until such time as the Defaulting Lender shall
                  no longer be in default of any of its obligations under this
                  Agreement. The terms of this Section shall not be construed to
                  increase or otherwise affect the Commitment of any Lender, or
                  relieve or excuse the performance by any Borrower of its
                  duties and obligations hereunder.

                  (h) Making of Non-Ratable Loans.

                           (i) In the event the Agent shall elect, with the
                  consent of the Bank, to have the terms of this Section 2.2(h)
                  apply to a requested Borrowing as described in Section 2.2(f),
                  the Bank shall make a Revolving Loan in the amount of such
                  Borrowing (any such Revolving Loan made solely by the Bank
                  pursuant to this Section 2.2(h) being referred to as a
                  "Non-Ratable Loan" and such Revolving Loans being referred to
                  collectively as "Non-Ratable Loans") available to a Borrower
                  on the Funding Date applicable thereto by transferring same
                  day funds to an account of such Borrower, designated in
                  writing by such Borrower and acceptable to the Agent. Each
                  Non-Ratable Loan is a Revolving Loan hereunder and shall be
                  subject to all the terms and conditions applicable to other
                  Revolving Loans except that all payments thereon shall be
                  payable to the Bank solely for its own account (and for the
                  account of the holder of any participation interest with
                  respect to such Revolving Loan). The Agent shall not request
                  the Bank to make any Non-Ratable Loan if (A) the Agent shall
                  have received written notice from any Lender that one or more
                  of the applicable conditions precedent set forth in Article 10
                  will not be satisfied on the requested Funding Date for the
                  applicable Borrowing, or (B) the requested Borrowing would
                  exceed the Availability on such Funding Date. The Bank shall
                  not otherwise be required to

LOAN AND SECURITY AGREEMENT - Page 36

<PAGE>   44

                  determine whether the applicable conditions precedent set
                  forth in Article 10 have been satisfied or the requested
                  Borrowing would exceed the Availability on the Funding Date
                  applicable thereto prior to making, in its sole discretion,
                  any Non-Ratable Loan.

                           (ii) The Non-Ratable Loans shall be secured by the
                  Agent's Liens in and to the Collateral, shall constitute
                  Revolving Loans and Obligations hereunder, and shall bear
                  interest at the rate applicable to the Revolving Loans from
                  time to time.

                  (i) Agent Advances.

                           (i) Subject to the limitations set forth in the
                  provisos contained in this Section 2.2(i), the Agent is hereby
                  authorized by the Borrowers and the Lenders, from time to time
                  in the Agent's sole discretion, (A) after the occurrence of a
                  Default or an Event of Default, or (B) at any time that any of
                  the other applicable conditions precedent set forth in Article
                  10 have not been satisfied, to make Base Rate Revolving Loans
                  to any Borrower on behalf of the Lenders which the Agent, in
                  its reasonable business judgment, deems necessary or desirable
                  (1) to preserve or protect the Collateral, or any portion
                  thereof, (2) to enhance the likelihood of, or maximize the
                  amount of, repayment of the Loans and other Obligations, or
                  (3) to pay any other amount chargeable to the Borrowers
                  pursuant to the terms of this Agreement, including costs, fees
                  and expenses as described in Section 15.7 (any of the advances
                  described in this Section 2.2(i) being hereinafter referred to
                  as "Agent Advances"); provided, that the Required Lenders may
                  at any time revoke the Agent's authorization contained in this
                  Section 2.2(i) to make Agent Advances, any such revocation to
                  be in writing and to become effective prospectively upon the
                  Agent's receipt thereof;

                           (ii) The Agent Advances shall be repayable on demand
                  and secured by the Agent's Liens in and to the Collateral,
                  shall constitute Revolving Loans and Obligations hereunder,
                  and shall bear interest at the rate applicable to Base Rate
                  Revolving Loans from time to time. The Agent shall notify each
                  Lender in writing of each such Agent Advance.

                  (j) Settlement. It is agreed that each Lender's funded portion
         of the Revolving Loans is intended by the Lenders to be equal at all
         times to such Lender's Pro Rata Share of the outstanding Revolving
         Loans. Notwithstanding such agreement, the Agent, the Bank, and the
         other Lenders agree (which agreement shall not be for the benefit of or
         enforceable by the Borrowers) that in order to facilitate the
         administration of this Agreement and the other Loan Documents,
         settlement among them as to the Revolving Loans, the Non-Ratable Loans
         and the Agent Advances shall take place on a periodic basis in
         accordance with the following provisions:

                           (i) The Agent shall request settlement ("Settlement")
                  with the Lenders on at least a weekly basis, or on a more
                  frequent basis if so determined by the Agent, (A) on behalf of
                  the Bank, with respect to each outstanding Non-Ratable Loan,

LOAN AND SECURITY AGREEMENT - Page 37

<PAGE>   45

                  (B) for itself, with respect to each Agent Advance, and (C)
                  with respect to collections received, in each case, by
                  notifying the Lenders of such requested Settlement by
                  telecopy, telephone or other similar form of transmission, of
                  such requested Settlement, no later than 11:00 a.m. (Dallas,
                  Texas time) on the date of such requested Settlement (the
                  "Settlement Date"). Each Lender (other than the Bank, in the
                  case of Non-Ratable Loans and the Agent in the case of Agent
                  Advances) shall make the amount of such Lender's Pro Rata
                  Share of the outstanding principal amount of the Non-Ratable
                  Loans and Agent Advances with respect to which Settlement is
                  requested available to the Agent, to such account of the Agent
                  as the Agent may designate, not later than 2:00 p.m. (Dallas,
                  Texas time), on the Settlement Date applicable thereto, which
                  may occur before or after the occurrence or during the
                  continuation of a Default or an Event of Default and whether
                  or not the applicable conditions precedent set forth in
                  Article 10 have then been satisfied. Such amounts made
                  available to the Agent shall be applied against the amounts of
                  the applicable Non-Ratable Loan or Agent Advance and, together
                  with the portion of such Non-Ratable Loan or Agent Advance
                  representing the Bank's Pro Rata Share thereof, shall
                  constitute Revolving Loans of such Lenders. If any such amount
                  is not made available to the Agent by any Lender on the
                  Settlement Date applicable thereto, the Agent shall be
                  entitled to recover such amount on demand from such Lender
                  together with interest thereon at the Federal Funds Rate for
                  the first three (3) days from and after the Settlement Date
                  and thereafter at the Interest Rate then applicable to the
                  Revolving Loans.

                           (ii) Notwithstanding the foregoing, not more than one
                  (1) Business Day after demand is made by the Agent (whether
                  before or after the occurrence of a Default or an Event of
                  Default and regardless of whether the Agent has requested a
                  Settlement with respect to a Non-Ratable Loan or Agent
                  Advance), each other Lender (A) shall irrevocably and
                  unconditionally purchase and receive from the Bank or the
                  Agent, as applicable, without recourse or warranty, an
                  undivided interest and participation in such Non-Ratable Loan
                  or Agent Advance equal to such Lender's Pro Rata Share of such
                  Non-Ratable Loan or Agent Advance and (B) if Settlement has
                  not previously occurred with respect to such Non-Ratable Loans
                  or Agent Advances, upon demand by the Bank or the Agent, as
                  applicable, shall pay to the Bank or the Agent, as applicable,
                  as the purchase price of such participation an amount equal to
                  one-hundred percent (100%) of such Lender's Pro Rata Share of
                  such Non-Ratable Loans or Agent Advances. If such amount is
                  not in fact made available to the Agent by any Lender, the
                  Agent shall be entitled to recover such amount on demand from
                  such Lender together with interest thereon at the Federal
                  Funds Rate for the first three (3) days from and after such
                  demand and thereafter at the Interest Rate then applicable to
                  Base Rate Revolving Loans.

                           (iii) From and after the date, if any, on which any
                  Lender purchases an undivided interest and participation in
                  any Non-Ratable Loan or Agent Advance pursuant to clause (ii)
                  preceding, the Agent shall promptly distribute to such Lender
                  at such address as such Lender may request in writing, such
                  Lender's Pro Rata Share

LOAN AND SECURITY AGREEMENT - Page 38

<PAGE>   46

                  of all payments of principal and interest and all proceeds of
                  Collateral received by the Agent in respect of such
                  Non-Ratable Loan or Agent Advance.

                           (iv) Between Settlement Dates, the Agent, to the
                  extent no Agent Advances or Non-Ratable Loans are outstanding,
                  may pay over to the Bank any payments received by the Agent,
                  which in accordance with the terms of this Agreement would be
                  applied to the reduction of the Revolving Loans, for
                  application to the Bank's Revolving Loans. If, as of any
                  Settlement Date, collections received since the immediately
                  preceding Settlement Date have been applied to the Bank's
                  Revolving Loans (other than to Non-Ratable Loans or Agent
                  Advances in which such Lender has not yet funded its purchase
                  of a participation pursuant to Section 2.2(j)(ii)), as
                  provided for in the previous sentence, the Bank shall pay to
                  the Agent for the accounts of the Lenders, to be applied to
                  the outstanding Revolving Loans of such Lenders, an amount
                  such that each Lender shall, upon receipt of such amount,
                  have, as of such Settlement Date, its Pro Rata Share of the
                  Revolving Loans. During the period between Settlement Dates,
                  the Bank with respect to Non-Ratable Loans, the Agent with
                  respect to Agent Advances, and each Lender with respect to the
                  Revolving Loans other than Non-Ratable Loans and Agent
                  Advances, shall be entitled to interest at the applicable rate
                  or rates payable under this Agreement on the actual average
                  daily amount of funds employed by the Bank, the Agent and the
                  other Lenders.

                  (k) Notation. The Agent shall record on its books the
         principal amount of the Revolving Loans owing to each Lender, including
         the Non-Ratable Loans owing to the Bank, and the Agent Advances owing
         to the Agent, from time to time. In addition, each Lender is
         authorized, at such Lender's option, to note the date and amount of
         each payment or prepayment of principal of such Lender's Revolving

                  OF CREDIT OR THE PROVISION OF ANY CREDIT SUPPORT OR
                  ENHANCEMENT IN CONNECTION THEREWITH OTHER THAN ANY CLAIMS,
                  DEMANDS, LIABILITIES, DAMAGES, LOSSES, COSTS, CHARGES, AND
                  EXPENSES RESULTING SOLELY FROM THE GROSS NEGLIGENCE OR WILLFUL
                  MISCONDUCT OF ANY SUCH INDEMNIFIED PERSON. THE AGREEMENT IN
                  THIS SECTION 2.4(i)(i) SHALL SURVIVE PAYMENT OF ALL
                  OBLIGATIONS. NOTHING CONTAINED IN THIS AGREEMENT IS INTENDED
                  TO LIMIT ANY BORROWER'S RIGHTS, IF ANY, WITH RESPECT TO THE

                  CREDIT ISSUER WHICH ARISE BY OPERATION OF LAW OR AS A RESULT
                  OF THE LETTER OF CREDIT APPLICATION AND RELATED DOCUMENTS
                  EXECUTED BY AND BETWEEN ANY BORROWER AND THE LETTER OF CREDIT
                  ISSUER.

                           (ii) Assumption of Risk by the Loan Parties. As among
                  the Loan Parties, the Lenders, and the Agent, the Loan Parties
                  assume all risks of the acts and omissions of, or misuse of
                  any of the Letters of Credit by, the respective beneficiaries
                  of such Letters of Credit. In furtherance and not in
                  limitation of the foregoing, the Lenders and the Agent shall
                  not be responsible for: (A) the form, validity, sufficiency,
                  accuracy, genuineness or legal effect of any document
                  submitted by any Person in connection with the application for
                  and issuance of and presentation of drafts with respect to any
                  of the Letters of Credit, even if it should prove to be in any
                  or all respects invalid, insufficient, inaccurate, fraudulent
                  or forged; (B) the validity or sufficiency of any instrument
                  transferring or assigning or purporting to transfer or assign
                  any Letter of Credit or the rights or benefits thereunder or
                  proceeds thereof, in whole or in part, which may prove to be
                  invalid or ineffective for any reason; (C) the failure of the
                  beneficiary of any Letter of Credit to comply duly with
                  conditions required in order to draw upon such Letter of
                  Credit; (D) errors, omissions, interruptions, or delays in
                  transmission or delivery of any messages, by mail, cable,
                  telegraph, telex or otherwise, whether or not they be in
                  cipher; (E) errors in interpretation of technical terms; (F)
                  any loss or delay in the transmission or otherwise of any
                  document required in order make a drawing under any Letter of
                  Credit or of the proceeds thereof; (G) the misapplication by
                  the beneficiary of any Letter of Credit of the proceeds of any
                  drawing under such Letter of Credit; or (H) any consequences
                  arising from causes beyond the control of the Lenders or the
                  Agent, including any act or omission, whether rightful or
                  wrongful, of any present or future de jure or de facto
                  Governmental Authority. None of the foregoing shall affect,
                  impair or prevent the vesting of any rights or powers of the
                  Agent or any Lender under this Section 2.4(i).

                           (iii) Exoneration. In furtherance and extension, and
                  not in limitation, of the specific provisions set forth above,
                  any action taken or omitted by the Agent or any Lender under
                  or in connection with any of the Letters of Credit or any
                  related certificates, if taken or omitted in good faith, shall
                  not put the Agent or any Lender under any resulting liability
                  to any Loan Party or relieve any Loan Party of any of its
                  obligations hereunder to any such Person.

                           (iv) Indemnification by Lenders. The Lenders agree to
                  indemnify the Letter of Credit Issuer (to the extent not
                  reimbursed by the Borrowers and without limiting the
                  obligations of the Borrowers hereunder) ratably in accordance
                  with their respective Pro Rata Shares, for any and all
                  liabilities, obligations, losses, damages, penalties, actions,
                  judgments, suits, costs, expenses (including attorneys' fees)
                  or disbursements of any kind and nature whatsoever that may be
                  imposed on, incurred by or asserted against the Letter of
                  Credit Issuer in any way relating to or arising out

LOAN AND SECURITY AGREEMENT - Page 45

<PAGE>   53

                  of any Letter of Credit or the transactions contemplated
                  thereby or any action taken or omitted by the Letter of Credit
                  Issuer under any Letter of Credit or any Loan Document in
                  connection therewith; provided that no Lender shall be liable
                  for any of the foregoing to the extent it arises from the
                  gross negligence or willful misconduct of the Person to be
                  indemnified. Without limitation of the foregoing, each Lender
                  agrees to reimburse the Letter of Credit Issuer promptly upon
                  demand for its Pro Rata Share of any costs or expenses payable
                  by any Borrower to the Letter of Credit Issuer, to the extent
                  that the Letter of Credit Issuer is not promptly reimbursed
                  for such costs and expenses by a Loan Party. The agreement
                  contained in this section shall survive payment in full of all
                  Obligations.

                           (v) Power of Attorney. In connection with all
                  Inventory financed by Letters of Credit, each Borrower hereby
                  appoints the Agent, or the Agent's designee, as its attorney,
                  with full power and authority: (A) to sign and/or endorse such
                  Borrower's name upon any warehouse or other receipts; (B) to
                  sign such Borrower's name on bills of lading and other
                  negotiable and non-negotiable documents; (C) to clear
                  Inventory through customs in the Agent's or such Borrower's
                  name, and to sign and deliver to customs officials powers of
                  attorney in such Borrower's name for such purpose; (D) to
                  complete in such Borrower's or the Agent's name, any order,
                  sale, or transaction, obtain the necessary documents in
                  connection therewith, and collect the proceeds thereof; and
                  (E) to do such other acts and things as are necessary in order
                  to enable the Agent to obtain possession or control of the
                  Inventory and to obtain payment of the Obligations. Neither
                  the Agent nor its designee, as such Borrower's attorney, will
                  be liable for any acts or omissions, nor for any error of
                  judgement or mistakes of fact or law. This power, being
                  coupled with an interest, is irrevocable until all Obligations
                  have been paid and satisfied.

                           (vi) Account Party. Each Borrower hereby authorizes
                  and directs any Letter of Credit Issuer to name any Borrower
                  as the "Account Party" therein and to deliver to the Agent all
                  instruments, documents and other writings and property
                  received by the Letter of Credit Issuer pursuant to the Letter
                  of Credit, and to accept and rely upon the Agent's
                  instructions and agreements with respect to all matters
                  arising in connection with the Letter of Credit or the
                  application therefor.

                           (vii) Control of Inventory. In connection with all
                  Inventory financed by Letters of Credit, each Borrower for
                  whose account such Letter of Credit was issued will, at the
                  Agent's request, instruct all suppliers, carriers, forwarders,
                  warehouses or others receiving or holding cash, checks,
                  Inventory, documents or instruments in which the Agent holds a
                  security interest to deliver them to the Agent and/or subject
                  to the Agent's order, and if they shall come into such
                  Borrower's possession, to deliver them, upon request, to the
                  Agent in their original form. Each such Borrower shall also,
                  at the Agent's request, designate the Agent as the consignee
                  on all bills of lading and other negotiable and non-negotiable
                  documents.

                  (j) Supporting Letter of Credit; Cash Collateral. If,
         notwithstanding the provisions of Section 2.4(b) and Section 12.1 any
         Letter of Credit is outstanding upon the termination of this Agreement,
         then upon such termination the Borrower for whose account such Letter
         of Credit was issued shall deposit with the Agent, for the ratable
         benefit of the Agent and the Lenders, with respect to each Letter of
         Credit then outstanding, as the Majority Lenders in their discretion
         shall specify, either (i) a standby letter of credit (a "Supporting
         Letter of Credit") in form and substance satisfactory to the Agent,
         issued by an issuer satisfactory to the Agent in an amount equal to the
         greatest amount for which such Letter of Credit may be drawn plus any
         fees and expenses associated with such Letter of Credit, under which
         Supporting Letter of Credit the Agent is entitled to draw amounts
         necessary to reimburse the Agent and the Lenders for payments to be
         made by the Agent and the Lenders under such Letter of Credit or under
         any credit support or enhancement provided through the Agent with
         respect thereto and any fees and expenses associated with such Letter
         of Credit, or (ii) cash in amounts necessary to reimburse the Agent and
         the Lenders for payments made by the Agent or the Lenders under such
         Letter of Credit or under any credit support or enhancement provided
         through the Agent with respect thereto and any fees and expenses
         associated with such Letter of Credit. Such Supporting Letter of Credit
         or deposit of cash shall be held by the Agent, for the ratable benefit
         of the Agent and the Lenders, as security for, and to provide for the
         payment of, the aggregate undrawn amount of such Letters of Credit
         remaining outstanding. Interest shall accrue on any such cash deposit
         at a rate acceptable to the Bank, which accrued interest shall be for
         the account of the Borrowers, subject to this Agreement.

         Section 2.5 Bank Products. Any Loan Party may request and the Bank
may, in its sole and absolute discretion, arrange for such Loan Party to obtain
from the Bank or the Bank's Affiliates Bank Products although no Loan Party is
required to do so. Each Loan Party agrees to indemnify and hold the Bank and the
Lenders harmless from any and all obligations now or hereafter owing to any
other Person by the Bank or any of the Lenders or the Bank's Affiliates arising
from or related to such Bank Products. Each Loan Party acknowledges and agrees
that the obtaining of Bank Products from the Bank or the Bank's Affiliates (a)
is in the sole and absolute discretion of the Bank or the Bank's Affiliates, and
(b) is subject to all rules and regulations of the Bank or the Bank's
Affiliates.

                                INTEREST AND FEES

         Section 3.1 Interest.

                  (a) Interest Rates. All outstanding Obligations shall bear
         interest on the unpaid principal amount thereof (including, to the
         extent permitted by law, on interest thereon not paid when due) from
         the date made until paid in full in cash at a rate determined by
         reference to the Base Rate or the LIBOR Rate and Sections 3.1(a)(i) or
         (ii), as applicable, but not to exceed the Maximum Rate described in
         Section 3.3. Subject to the provisions of Section 3.2, any of the Loans
         may be converted into, or continued as, Base Rate Loans or LIBOR Rate

LOAN AND SECURITY AGREEMENT - Page 47

<PAGE>   55

         Loans in the manner provided in Section 3.2. If at any time Loans are
         outstanding with respect to which notice has not been delivered to the
         Agent in accordance with the terms of this Agreement specifying the
         basis for determining the interest rate applicable thereto, then those
         Loans shall be Base Rate Loans and shall bear interest at a rate
         determined by reference to the Base Rate until notice to the contrary
         has been given to the Agent in accordance with this Agreement and such
         notice has become effective. Except as otherwise provided herein, the
         outstanding Obligations shall bear interest as follows:

                           (i) For all Base Rate Revolving Loans and other
                  Obligations (other than LIBOR Rate Loans) at a fluctuating per
                  annum rate equal to the lesser of (A) the Base Rate plus the
                  Applicable Margin or (B) the Maximum Rate; and

                           (ii) For all LIBOR Revolving Loans at a per annum
                  rate equal to the lesser of (A) the LIBOR Rate plus the
                  Applicable Margin or (B) the Maximum Rate.

         Each change in the Base Rate shall be reflected in the interest rate
         described in clause (i) above as of the effective date of such change.
         Subject to Section 3.7, all interest charges shall be computed on the
         basis of a year of 360 days and actual days elapsed (which results in
         more interest being paid than if computed on the basis of a 365-day
         year). Interest accrued on all Loans will be payable in arrears (A)
         with respect to Base Rate Loans, on the next Business Day following the
         last day of each calendar month and (B) with respect to LIBOR Rate
         Loans, on the last day of each corresponding Interest Period (and in
         the case of an Interest Period of greater than three (3) months, at
         three-month intervals after the first day of such Interest Period), in
         each case continuing until all Obligations have been irrevocably paid
         in full.

                  (b) Default Rate. If any Default or Event of Default occurs
         and is continuing and the Majority Lenders in their discretion so
         elect, then, while any such Default or Event of Default is outstanding,
         all of the Obligations shall bear interest at a per annum rate equal to
         the lesser of (A) the Default Rate applicable thereto or (B) the
         Maximum Rate.

         Section 3.2 Conversion and Continuation Elections.

                  (a) The Borrowers may, upon irrevocable written notice to the
         Agent in accordance with Section 3.2(b):

                           (i) elect, as of any Business Day, in the case of
                  Base Rate Loans to convert any such Loans (or any part thereof
                  in an amount not less than $500,000, or that is in an integral
                  multiple of $100,000 in excess thereof) into LIBOR Rate Loans;
                  or

                           (ii) elect, as of the last day of the applicable
                  Interest Period, to continue any LIBOR Rate Loans having
                  Interest Periods expiring on such day (or any part thereof in
                  an amount not less than $500,000, or that is in an integral
                  multiple of $100,000 in excess thereof);

LOAN AND SECURITY AGREEMENT - Page 48

<PAGE>   56

         provided, that if at any time the aggregate amount of LIBOR Rate Loans
         in respect of any Borrowing is reduced, by payment, prepayment, or
         conversion of part thereof to be less than $500,000, such LIBOR Rate
         Loans shall automatically convert into Base Rate Loans, and on and
         after such date the right of the Borrowers to continue such Loans as,
         and convert such Loans into, LIBOR Rate Loans, as the case may be,
         shall terminate.

                  (b) The Borrowers shall deliver a notice of
         conversion/continuation ("Notice of Conversion/Continuation") to be
         received by the Agent not later than 11:00 a.m. (Dallas, Texas time) at
         least three (3) Business Days in advance of the Conversion/Continuation
         Date, if the Loans are to be converted into or continued as LIBOR Rate
         Loans and specifying:

                           (i) the proposed Conversion/Continuation Date;

                           (ii) the aggregate amount of Loans to be converted or
                  renewed;

                           (iii) the type of Loans resulting from the proposed
                  conversion or continuation; and

                           (iv) the duration of the requested Interest Period.

                  (c) If upon the expiration of any Interest Period applicable
         to LIBOR Rate Loans, the Borrowers have failed to select timely a new
         Interest Period to be applicable to LIBOR Rate Loans or if any Default
         or Event of Default then exists, the Borrowers shall be deemed to have
         elected to convert such LIBOR Rate Loans into Base Rate Loans effective
         as of the expiration date of such Interest Period.

                  (d) The Agent will promptly notify each Lender of its receipt
         of a Notice of Conversion/Continuation. All conversions and
         continuations shall be made ratably according to the respective
         outstanding principal amounts of the Loans with respect to which the
         notice was given held by each Lender.

                  (e) During the existence of a Default or Event of Default, the
         Borrowers may not elect to have a Loan converted into or continued as a
         LIBOR Rate Loan.

                  (f) After giving effect to any conversion or continuation of
         Loans, there may not be more than six (6) different Interest Periods in
         effect hereunder.

         Section 3.3 Maximum Interest Rate. If, in any month, any interest
rate, absent such limitation, would have exceeded the Maximum Rate, then the
interest rate for that month shall be the Maximum Rate, and, if in future
months, that interest rate would otherwise be less than the Maximum Rate, then
that interest rate shall remain at the Maximum Rate until such time as the
amount of interest paid hereunder equals the amount of interest which would have
been paid if the same had not been limited by the Maximum Rate. In the event
that, upon payment in full of the Obligations, the total amount of interest paid
or accrued under the terms of this Agreement is less than the total

LOAN AND SECURITY AGREEMENT - Page 49

<PAGE>   57

amount of interest which would, but for this Section 3.3, have been paid or
accrued if the interest rates otherwise set forth in this Agreement had at all
times been in effect, then the Borrowers shall, to the extent permitted by
applicable law, pay the Agent, for the account of the Lenders, an amount equal
to the excess of (a) the lesser of (i) the amount of interest which would have
been charged if the Maximum Rate had, at all times, been in effect or (ii) the
amount of interest which would have accrued had the interest rates otherwise set
forth in this Agreement, at all times, been in effect over (b) the amount of
interest actually paid or accrued under this Agreement.

         Section 3.4 Unused Line Fee. Until the Loans have been paid in full
and the Agreement terminated, the Borrowers agree to pay, on the first day of
each month and on the Termination Date, to the Agent, for the account of the
Lenders, in accordance with their respective Pro Rata Shares, an unused line fee
(the "Unused Line Fee") equal to the Unused Line Fee Percentage times the amount
by which the Maximum Revolver Amount exceeded the sum of the average daily
outstanding amount of Revolving Loans and the average daily undrawn face amount
of all outstanding Letters of Credit, during the immediately preceding month or
shorter period if calculated on the Termination Date. The Unused Line Fee shall
be computed on the basis of a 360-day year for the actual number of days
elapsed. All payments received by the Agent on account of Accounts or as
proceeds of other Collateral shall be deemed to be credited to the Borrowers'
Loan Account immediately upon receipt for purposes of calculating the Unused
Line Fee pursuant to this Section 3.4.

         Section 3.5 Letter of Credit Fee. The Borrowers agree to pay to the
Agent, for the account of the Lenders, in accordance with their respective Pro
Rata Shares, for each Letter of Credit, a fee (the "Letter of Credit Fee") equal
to the Letter of Credit Fee Percentage per annum of the undrawn face amount of
each Letter of Credit, plus all out-of-pocket costs, fees and expenses incurred
by the Agent in connection with the application for, processing of, issuance of,
or amendment to any Letter of Credit, which costs, fees and expenses could
include a "fronting fee" payable to such issuer. The Letter of Credit Fee shall
be payable monthly in arrears on the first day of each month following any month
in which a Letter of Credit was issued and/or in which a Letter of Credit
remains outstanding. The Letter of Credit Fee shall be computed on the basis of
a 360-day year for the actual number of days elapsed.

         Section 3.6 Other Fees. The Borrowers agree to pay all other fees and
expenses set forth in the certain letter agreement, dated as of the Closing Date
among the Agent, the Borrowers and the Parent.

         Section 3.7 Interest Limitation. The Agent, the Lenders and the Loan
Parties each acknowledges, agrees and declares that it is its intention to
expressly comply with all Requirements of Law in respect of limitations on the
amount or rate of interest that can legally be contracted for, charged or
received under or in connection with the Loan Documents. Notwithstanding
anything to the contrary contained in any Loan Document (even if any such
provision expressly declares that it controls all other provision of the Loan
Documents), in no contingency or event whatsoever shall the amount of interest
(including the aggregate of all charges, fees, benefits or other compensation
which constitutes interest under any Requirement of Law) under the Loan
Documents paid by any Borrower, received by the Agent, the Letter of Credit
Issuer or any Lender, agreed to be paid by any Borrower, or requested or
demanded to be paid by the Agent, the Letter of Credit Issuer or any

LOAN AND SECURITY AGREEMENT - Page 50

Lender, exceed the Maximum Rate, and all provisions of the Loan Documents in
respect of the contracting for, charging, or receiving compensation for the use,
forbearance, or detention of money shall be limited as provided by this Section
3.7. In the event any such interest is paid to the Agent, the Letter of Credit
Issuer or any Lender by the Borrowers, or any of them, in an amount or at a rate
which would exceed the Maximum Rate, the Agent, the Letter of Credit Issuer or
such Lender, as the case may be, shall automatically apply such excess to any
unpaid amount of the Obligations other than interest, in inverse order of
maturity, or if the amount of such excess exceeds said unpaid amount, such
excess shall be paid to the paying Borrowers or Borrower, as applicable. All
interest paid, or agreed to be paid, by any Borrower, or taken, reserved or
received by the Agent, the Letter of Credit Issuer or any Lender, shall be
amortized, prorated, spread, and allocated in respect of the Obligations
throughout the full term of this Agreement. Notwithstanding any provision
contained in any of the Loan Documents, or in any other related documents
executed pursuant hereto, neither the Agent, the Letter of Credit Issuer nor any
Lender shall ever be entitled to charge, receive, take, reserve, collect, or
apply as interest any amount which, together with all other interest under the
Loan Documents would result in a rate of interest under the Loan Documents in
excess of the Maximum Rate and, in the event the Agent, the Letter of Credit
Issuer or any Lender ever charges, receives, takes, reserves, collects, or
applies any amount in respect of the Borrowers, or any of them, that otherwise
would, together with all other interest under the Loan Documents, be in excess
of the Maximum Rate, such amount shall automatically be deemed to be applied in
reduction of the unpaid principal balance of the Obligations and, if such
principal balance is paid in full, any remaining excess shall forthwith be paid
to the applicable Borrowers or Borrower. The Borrowers, the Agent, the Letter of
Credit Issuer and the Lenders shall, to the maximum extent permitted under any
Requirement of Law, (i) characterize any non-principal payment as a standby fee,
commitment fee, prepayment charge, delinquency charge, expense or reimbursement
for a third-party expense rather than as interest and (ii) exclude prepayments,
acceleration and the effect thereof. Nothing in any Loan Document shall be
construed or so operate as to require or obligate the Borrowers, or any of them,
to pay any interest, fees, costs, or charges greater than is permitted by any
Requirement of Law. Subject to the foregoing, the Borrowers hereby agree that
the actual effective rate of interest from time to time existing under the Loan
Documents, including all amounts agreed to by the Borrowers or charged or
received by the Agent, the Letter of Credit Issuer or the Lenders pursuant to
and in accordance with the Loan Documents, which may be deemed to be interest
under any Requirement of Law, shall be deemed to be a rate which is agreed to
and stipulated by the Borrowers and the Lenders in accordance with Requirements
of Law.

                                   ARTICLE 4

                            PAYMENTS AND PREPAYMENTS

         Section 4.1 Revolving Loans. The Borrowers shall repay the outstanding
principal balance of the Revolving Loans, plus all accrued but unpaid interest
thereon, on the Termination Date. The Borrowers may prepay Revolving Loans at
any time, and reborrow subject to the terms of this Agreement; provided,
however, that with respect to any LIBOR Revolving Loans prepaid prior to the
expiration date of the Interest Period applicable thereto, the Borrowers promise
to pay to the Agent for account of the Lenders the amounts described in Section
5.4. In addition, and without limiting the generality of the foregoing, upon
demand the Borrowers promise to pay to the Agent,

for account of the Lenders, the amount, without duplication, by which the
Aggregate Revolver Outstanding exceeds the Borrowing Base.

         Section 4.2 Reduction of Commitments; Termination of Facility.

                  (a) The Borrowers may reduce the Maximum Revolver Amount to an
         amount, not less than $40,000,000, as may be designated by the
         Borrowers at any time effective upon thirty (30) days prior written
         notice thereof to the Agent and the Lenders, provided, that (i) the
         first of any such reductions shall be in an amount of at least
         $5,000,000 and any such subsequent reduction shall be in an amount of
         at least $1,000,000 or any integral multiple of $1,000,000 in excess
         thereof and (ii) each such reduction shall be permanent. The Lenders
         shall have no obligation at any time to increase the Maximum Revolver
         Amount following any such reduction. No notice of reduction shall be
         effective to reduce the Maximum Revolver Amount to an amount less than
         $40,000,000.

                  (b) The Borrowers may terminate this Agreement upon at least
         thirty (30) Business Days' notice to the Agent and the Lenders, upon
         (a) the payment in full of all outstanding Revolving Loans, together
         with accrued interest thereon, and the cancellation and return of all
         outstanding Letters of Credit, (b) the payment of the early termination
         fee set forth in the next sentence, (c) the payment in full in cash of
         all other Obligations together with accrued interest thereon, and (d)
         with respect to any LIBOR Rate Loans prepaid in connection with such
         termination prior to the expiration date of the Interest Period
         applicable thereto, the payment of the amounts described in Section
         5.4. If this Agreement is terminated at any time prior to the Stated
         Termination Date, whether pursuant to this Section or pursuant to
         Section 11.2, the Loan Parties shall pay to the Agent, for the account
         of the Lenders, an early termination fee determined in accordance with
         the following table:

                                                              the 180 days (or lesser period if

                                                              prior to the date of termination.

                                                              termination.

Notwithstanding the foregoing, no such early termination fee shall be payable in
the event this Agreement is terminated at any time after the first Anniversary
Date in connection with refinancing the Obligations in a transaction in which
the Bank or any of its Affiliates is administrative agent and a lender.

         Section 4.3 Reserved.

         Section 4.4 Prepayments from Capex Reimbursements. An amount equal to
all Capex Reimbursements shall be paid to the Agent, promptly upon receipt
thereof, for application to the Obligations in such manner as the Agent shall
determine in its sole discretion.

         Section 4.5 Prepayments from Asset Dispositions. All proceeds or other
cash payments received by any Loan Party or Restricted Subsidiary pursuant to
any transaction of merger, reorganization, consolidation, transfer, sale,
assignment, lease or other disposition allowed by clauses (a) and (c) through
(g) of Section 9.9, net of reasonable costs and expenses, shall be paid to the
Agent, promptly upon such receipt, for application to the Obligations in such
manner as the Agent shall determine in its sole discretion.

         Section 4.6 Payments by the Borrower.

                  (a) All payments to be made by the Borrowers shall be made
         without setoff, recoupment or counterclaim. Except as otherwise
         expressly provided herein, all payments by the Borrowers shall be made
         to the Agent for the account of the Lenders at the Agent's address set
         forth in Section 15.8, and shall be made in Dollars and in immediately
         available funds, no later than 2:00 p.m. (Dallas, Texas time) on the
         date specified herein. Any payment received by the Agent later than
         2:00 p.m. (Dallas, Texas time) shall be deemed to have been received on
         the following Business Day and any applicable interest or fee shall
         continue to accrue.

                  (b) Subject to the provisions set forth in the definition of
         "Interest Period" herein, whenever any payment is due on a day other
         than a Business Day, such payment shall be made on the following
         Business Day, and such extension of time shall in such case be included
         in the computation of interest or fees, as the case may be.

                  (c) Unless the Agent receives notice from the Borrowers prior
         to the date on which any payment is due to the Lenders that the
         Borrowers will not make such payment in full as and when required, the
         Agent may assume that the Borrowers have made such payment in full to
         the Agent on such date in immediately available funds and the Agent may
         (but shall not be so required), in reliance upon such assumption,
         distribute to each Lender on such due date an amount equal to the
         amount then due such Lender. If and to the extent the Borrowers have
         not made such payment in full to the Agent, each Lender shall repay to
         the Agent on demand such amount distributed to such Lender, together
         with interest thereon at the Federal Funds Rate for each day from the
         date such amount is distributed to such Lender until the date repaid.

         Section 4.7 Payments as Revolving Loans. All payments of principal,
interest, reimbursement obligations in connection with Letters of Credit, fees,
premiums and other sums payable hereunder, including all reimbursement for
expenses pursuant to Section 15.7, may, at the option of the Agent, in its sole
discretion, subject only to the terms of this Section 4.7, be paid from the
proceeds of Revolving Loans made hereunder, whether made following a request by
the Borrowers pursuant to Section 2.2 or a deemed request as provided in this
Section 4.7. The Borrowers hereby irrevocably authorize the Agent to charge the
Loan Account for the purpose of paying principal, interest, reimbursement
obligations in connection with Letters of Credit, fees, premiums and other sums
payable hereunder, including reimbursing expenses pursuant to Section 15.7, and
agrees that all such amounts charged shall constitute Revolving Loans (including
Non-Ratable Loans and Agent Advances) and that all such Revolving Loans so made
shall be deemed to have been requested by Borrowers pursuant to Section 2.2.

         Section 4.8 Apportionment, Application and Reversal of Payments.
Aggregate principal and interest payments shall be apportioned ratably among the
Lenders (according to the unpaid principal balance of the Loans to which such
payments relate held by each Lender) and payments of the fees shall, as
applicable, be apportioned ratably among the Lenders. All payments shall be
remitted to the Agent and all such payments not relating to principal or
interest of specific Loans, or not constituting payment of specific fees, and
all proceeds of Accounts or other Collateral received by the Agent, shall be
applied, ratably, subject to the provisions of this Agreement, first, to pay any
fees, indemnities or expense reimbursements then due to the Agent from the
Borrowers; second, to pay any fees or expense reimbursements then due to the
Lenders from the Borrowers; third, to pay interest due in respect of all
Revolving Loans, including Non-Ratable Loans and Agent Advances; fourth, to pay
or prepay principal of the Non-Ratable Loans and Agent Advances; fifth, to pay
or prepay principal of the Revolving Loans (other than Non-Ratable Loans and
Agent Advances) and unpaid reimbursement obligations in respect of Letters of
Credit; sixth, to the payment of any other Obligation due to the Agent or any
Lender by the Borrowers; and seventh, to the payment of all Obligations, if any,
arising from or in connection with Bank Products. Notwithstanding anything to
the contrary contained in this Agreement, unless so directed by a Borrower, or
unless an Event of Default is outstanding, neither the Agent nor any Lender
shall apply any payments which it receives to any LIBOR Revolving Loan, except
(a) on the expiration date of the Interest Period applicable to any such LIBOR
Rate Loan, or (b) in the event, and only to the extent, that there are no
outstanding Base Rate Revolving Loans. The Agent shall promptly distribute to
each Lender, pursuant to the applicable wire transfer instructions received from
each Lender in writing, such funds as it may be entitled to receive, subject to
a Settlement delay as provided for in Section 2.2(j). The Agent and the Lenders
shall have the continuing and exclusive right to apply and reverse and reapply
any and all such proceeds and payments to any portion of the Obligations.

         Section 4.9 Indemnity for Returned Payments. If after receipt of any
payment which is applied to the payment of all or any part of the Obligations,
the Agent or any Lender is for any reason compelled to surrender such payment or
proceeds to any Person because such payment or application of proceeds is
invalidated, declared fraudulent, set aside, determined to be void or voidable
as a preference, impermissible setoff, or a diversion of trust funds, or for any
other reason, then the Obligations or part thereof intended to be satisfied
shall be revived and continued and this Agreement shall continue in full force
as if such payment or proceeds had not been received by the Agent or such

LOAN AND SECURITY AGREEMENT - Page 54

<PAGE>   62

Lender and the Loan Parties shall be liable to pay to the Agent and the Lenders,
and each Loan Party hereby does indemnify the Agent and the Lenders and hold the
Agent and the Lenders harmless for the amount of such payment or proceeds
surrendered. The provisions of this Section 4.9 shall be and remain effective
notwithstanding any contrary action which may have been taken by the Agent or
any Lender in reliance upon such payment or application of proceeds, and any
such contrary action so taken shall be without prejudice to the Agent's and the
Lenders' rights under this Agreement and shall be deemed to have been
conditioned upon such payment or application of proceeds having become final and
irrevocable. The provisions of this Section 4.9 shall survive the termination of
this Agreement.

         Section 4.10 The Agent's and the Lenders' Books and Records; Monthly
Statements. The Loan Parties agree that the Agent's and each Lender's books and
records showing the Obligations and the transactions pursuant to this Agreement
and the other Loan Documents shall be admissible in any action or proceeding
arising therefrom, and shall constitute rebuttably presumptive proof thereof,
irrespective of whether any Obligation is also evidenced by a promissory note or
other instrument. The Agent will provide to the Borrowers a monthly statement of
Loans, payments, and other transactions pursuant to this Agreement. Such
statement shall be deemed correct, accurate, and binding on the Borrowers and an
account stated (except for reversals and reapplications of payments made as
provided in Section 4.8 and corrections of errors discovered by the Agent),
unless a Borrower notifies the Agent in writing to the contrary within thirty
(30) days after such statement is rendered. In the event a timely written notice
of objections is given by a Borrower, only the items to which exception is
expressly made will be considered to be disputed.

                                   ARTICLE 5

                     TAXES, YIELD PROTECTION AND ILLEGALITY

         Section 5.1 Taxes.

                  (a) Any and all payments by or on behalf of the Borrowers, or
         any of them, to each Lender or the Agent under this Agreement and any
         other Loan Document shall be made free and clear of, and without
         deduction or withholding for any Taxes. In addition, the Borrowers
         shall pay all Other Taxes.

                  (b) The Borrowers agree to indemnify and hold harmless each
         Lender and the Agent for the full amount of Taxes or Other Taxes
         (including any Taxes or Other Taxes imposed by any jurisdiction on
         amounts payable under this Section) paid by the Lender or the Agent and
         any liability (including penalties, interest, additions to tax and
         expenses) arising therefrom or with respect thereto, whether or not
         such Taxes or Other Taxes were correctly or legally asserted. Payment
         under this indemnification shall be made within 30 days after the date
         the Lender or the Agent makes written demand therefor.

                  (c) If the Borrowers shall be required by law to deduct or
         withhold any Taxes or Other Taxes from or in respect of any sum payable
         hereunder to any Lender or the Agent, then:

LOAN AND SECURITY AGREEMENT - Page 55

<PAGE>   63

                           (i) the sum payable shall be increased as necessary
                  so that after making all required deductions and withholdings
                  (including deductions and withholdings applicable to
                  additional sums payable under this Section) such Lender or the
                  Agent, as the case may be, receives an amount equal to the sum
                  it would have received had no such deductions or withholdings
                  been made;

                           (ii) the Borrowers shall make such deductions and
                  withholdings;

                           (iii) the Borrowers shall pay the full amount
                  deducted or withheld to the relevant taxing authority or other
                  authority in accordance with applicable law; and

                           (iv) the Borrowers shall also pay to each Lender or
                  the Agent for the account of such Lender, at the time interest
                  is paid, all additional amounts which the respective Lender
                  specifies as necessary to preserve the after-tax yield the
                  Lender would have received if such Taxes or Other Taxes had
                  not been imposed.

                  (d) Within 30 days after the date of any payment by the
         Borrowers of Taxes or Other Taxes, the Borrowers shall furnish the
         Agent the original or a certified copy of a receipt evidencing payment
         thereof, or other evidence of payment satisfactory to the Agent.

                  (e) If the Borrowers are required to pay additional amounts to
         any Lender or the Agent pursuant to subsection (c) of this Section,
         then such Lender shall use reasonable efforts (consistent with legal
         and regulatory restrictions) to change the jurisdiction of its lending
         office so as to eliminate any such additional payment by the Borrowers
         which may thereafter accrue, if such change in the judgment of such
         Lender is not otherwise disadvantageous to such Lender.

         Section 5.2 Illegality.

                  (a) If any Lender determines that the introduction of any
         Requirement of Law, or any change in any Requirement of Law, or in the
         interpretation or administration of any Requirement of Law, has made it
         unlawful, or that any central bank or other Governmental Authority has
         asserted that it is unlawful, for any Lender or its applicable lending
         office to make LIBOR Rate Loans, then, on notice thereof by the Lender
         to the Borrowers through the Agent, any obligation of that Lender to
         make LIBOR Rate Loans shall be suspended until the Lender notifies the
         Agent and the Borrowers that the circumstances giving rise to such
         determination no longer exist.

                  (b) If a Lender determines that it is unlawful to maintain any
         LIBOR Rate Loan, the Borrowers shall, upon receipt of notice of such
         fact and demand from such Lender (with a copy to the Agent), prepay in
         full such LIBOR Rate Loans of that Lender then outstanding, together
         with interest accrued thereon and amounts required under Section 5.4,
         either on the last day of the Interest Period thereof, if the Lender
         may lawfully continue to maintain such LIBOR Rate Loans to such day, or
         immediately, if the Lender may not lawfully continue to

LOAN AND SECURITY AGREEMENT - Page 56

<PAGE>   64

         maintain such LIBOR Rate Loan. If the Borrowers are required to so
         prepay any LIBOR Rate Loans, then concurrently with such prepayment,
         the Borrowers shall borrow from the affected Lender, in the amount of
         such repayment, a Base Rate Loan.

         Section 5.3 Increased Costs and Reduction of Return.

                  (a) If any Lender determines that due to either (i) the
         introduction of or any change in the interpretation of any law or
         regulation or (ii) the compliance by that Lender with any guideline or
         request from any central bank or other Governmental Authority (whether
         or not having the force of law), there shall be any increase in the
         cost to such Lender of agreeing to make or making, funding or
         maintaining any LIBOR Rate Loans, then the Borrowers shall be liable
         for, and shall from time to time, upon demand (with a copy of such
         demand to be sent to the Agent), pay to the Agent for the account of
         such Lender, additional amounts as are sufficient to compensate such
         Lender for such increased costs.

                  (b) If any Lender shall have determined that (i) the
         introduction of any Capital Adequacy Regulation, (ii) any change in any
         Capital Adequacy Regulation, (iii) any change in the interpretation or
         administration of any Capital Adequacy Regulation by any central bank
         or other Governmental Authority charged with the interpretation or
         administration thereof, or (iv) compliance by the Lender or any
         corporation or other entity controlling the Lender with any Capital
         Adequacy Regulation, affects or would affect the amount of capital
         required or expected to be maintained by the Lender or any corporation
         or other entity controlling the Lender and (taking into consideration
         such Lender's or such corporation's or other entity's policies with
         respect to capital adequacy and such Lender's desired return on
         capital) determines that the amount of such capital is increased as a
         consequence of its Commitments, loans, credits or obligations under
         this Agreement, then, upon demand of such Lender to the Borrowers
         through the Agent, the Borrowers shall pay to the Lender, from time to
         time as specified by the Lender, additional amounts sufficient to
         compensate the Lender for such increase.

         Section 5.4 Funding Losses. The Borrowers shall reimburse each Lender
and hold each Lender harmless from any loss or expense which the Lender may
sustain or incur as a consequence of:

                  (a) the failure of the Borrowers to make on a timely basis any
         payment of principal of any LIBOR Rate Loan;

                  (b) the failure of the Borrowers to borrow, continue or
         convert a Loan after the Borrowers have given (or are deemed to have
         given) a Notice of Borrowing or a Notice of Conversion/ Continuation;

                  (c) the prepayment or other payment (including after

including any such loss or expense arising from the liquidation or reemployment
of funds obtained by it to maintain its LIBOR Rate Loans or from fees payable to
terminate the deposits from which such funds were obtained.

         Section 5.5 Inability to Determine Rates. If the Agent determines that
for any reason adequate and reasonable means do not exist for determining the
LIBOR Rate for any requested Interest Period with respect to a proposed LIBOR
Rate Loan, or that the LIBOR Rate for any requested Interest Period with respect
to a proposed LIBOR Rate Loan does not adequately and fairly reflect the cost to
the Lenders of funding such Loan, the Agent will promptly so notify the
Borrowers and each Lender. Thereafter, the obligation of the Lenders to make or
maintain LIBOR Rate Loans hereunder shall be suspended until the Agent revokes
such notice in writing. Upon receipt of such notice, the Borrowers may revoke
any Notice of Borrowing or Notice of Conversion/Continuation then submitted by
it. If the Borrowers do not revoke such Notice, the Lenders shall make, convert
or continue the Loans, as proposed by the Borrowers, in the amount specified in
the applicable notice submitted by the Borrowers, but such Loans shall be made,
converted or continued as Base Rate Loans instead of LIBOR Rate Loans.

         Section 5.6 Certificates of Lenders. Any Lender claiming reimbursement
or compensation under this Article 5 shall deliver to the Borrowers (with a copy
to the Agent) a certificate setting forth in reasonable detail the amount
payable to the Lender hereunder and such certificate shall be conclusive and
binding on the Borrowers in the absence of manifest error.

         Section 5.7 Survival. The agreements and obligations of the Borrower
in this Article 5 shall survive the payment of all other Obligations.

         Section 5.8 Replacement of Affected Lender. Within thirty (30) days
after receipt by the Borrowers of written notice and demand from any Lender for
any payment under the terms of Section 5.1 or Section 5.3 then, subject to this
Section 5.8, the Borrowers may, at their option, notify the Agent and such
Lender (the "Affected Lender") of their intention to obtain, at the Borrowers'
sole expense, a replacement Lender ("Replacement Lender") to purchase the
Affected Lender's Revolving Loans and its obligations under the Loan Documents.
Subject to this Section 5.8, the Borrowers shall, within thirty (30) days
following the delivery of such notice from the Borrowers, cause the Replacement
Lender to purchase (and the Affected Lender hereby agrees to sell and convey to
such Replacement Lender) the Revolving Loans of the Affected Lender and assume
the Affected Lender's Commitment and obligations hereunder in accordance with
the terms of an Assignment and Acceptance for cash in an aggregate amount equal
to the aggregate unpaid principal of the Revolving Loans held by such Affected
Lender, all unpaid interest and fees accrued thereon or with respect thereto,
and all other Obligations owed to such Affected Lender, including amounts owed
under Section 5.1 or Section 5.3 (but excluding any amount pursuant to Section
4.2). Notwithstanding the foregoing, the (a) Borrowers shall continue to be
obligated to pay to the Affected Lender in full all amounts then demanded and
due under Section 5.1 or Section 5.3 in accordance with the terms of this
Agreement, (b) neither the Agent nor any Lender shall have any obligation to
find a Replacement Lender, (c) the Replacement Lender must be acceptable to the
Agent in its reasonable discretion and (d) the Bank may not be replaced under
this Section 5.8 without its consent.

                           (x) all accessions to, substitutions for and
                  replacements, products and proceeds of any of the foregoing,

                  foregoing;

         All of the property enumerated in this Section 6.1(a), together with
         all other property of such Loan Party in which the Agent or any Lender
         may at any time be granted a Lien, is herein collectively referred to
         as the "Collateral."

                  (b) All of the Obligations (excluding Existing Obligations in
         the case of property owned by a Newly Obligated party) shall be secured
         by all of the Collateral. Each Loan Party that is a Borrower
         acknowledges and expressly agrees with the Agent and each Lender that
         the grant by such Borrower of the Agent's Lien in the Collateral of
         such Borrower as security for Obligations of the other Loan Parties is
         required solely as a condition to, and is given solely as inducement
         for and in consideration of, credit or accommodations extended or to be
         extended under the Loan Documents to any or all of the other Loan
         Parties and is not required or given as a condition of extensions of
         credit to such Borrower.

         Section 6.2 Perfection and Protection of Security Interest.

                  (a) Each Loan Party shall, at its expense, perform all steps
         requested by the Agent at any time to perfect, maintain, protect, and
         enforce the Agent's Liens, including: (i) executing and filing
         financing or continuation statements, and amendments thereof, in form
         and substance satisfactory to the Agent; (ii) executing and delivering
         the Maritime Security Documents; (iii) delivering to the Agent the
         originals of all instruments, documents, and chattel paper, and all
         other Collateral of which the Agent determines it should have physical
         possession in order to perfect and protect the Agent's security
         interest therein, duly pledged, endorsed or assigned to the Agent
         without restriction; (iv) delivering to the Agent warehouse receipts
         covering any portion of the Collateral located in warehouses and for
         which warehouse receipts are issued and certificates of title covering
         any portion of the collateral for which certificates of title have been
         issued; (v) when an Event of Default exists, transferring Inventory to
         warehouses or other locations designated by the Agent; (vi) placing
         notations on its books of account to disclose the Agent's security
         interest; (vii) delivering to the Agent all letters of credit on which
         it is named beneficiary; and (viii) taking such other steps as are
         deemed necessary or desirable by the Agent to maintain and protect the
         Agent's Liens. To the extent permitted by applicable law, the Agent may
         file, without any Loan Party's signature, one or more financing
         statements disclosing the Agent's Liens. Each Loan Party agrees that a
         carbon, photographic, photostatic, or other reproduction of this
         Agreement or of a financing statement is sufficient as a financing
         statement.

                  (b) If any Collateral is at any time in the possession or
         control of any warehouseman, bailee or any Loan Party's agents or
         processors, then such Loan Party shall notify the Agent thereof and
         shall, at the request of the Agent, notify such Person of the Agent's
         security interest in such Collateral and instruct such Person to hold
         all such Collateral

LOAN AND SECURITY AGREEMENT - Page 60

         for the Agent's account subject to the Agent's instructions. If at any
         time any Collateral is located on any operating facility of a Loan
         Party which is not owned by such Loan Party, then such Loan Party
         shall, at the request of the Agent, obtain written subordinations, in
         form and substance satisfactory to the Agent, of all present and future
         Liens to which the owner or lessor of such premises may be entitled to
         assert against the Collateral.

                  (c) From time to time, each Loan Party shall, upon the Agent's
         request, execute and deliver confirmatory written instruments pledging
         to the Agent, for the ratable benefit of the Agent and the Lenders, the
         Collateral with respect to such Loan Party, but the failure to do so
         shall not affect or limit any security interest or any other rights of
         the Agent or any Lender in and to the Collateral with respect to such
         Loan Party. So long as this Agreement is in effect and until all
         Obligations have been fully satisfied, the Agent's Liens shall continue
         in full force and effect in all Collateral (whether or not deemed
         eligible for the purpose of calculating the Availability or as the
         basis for any advance, loan, extension of credit, or other financial
         accommodation).

                  (d) To the extent any Loan Party is or becomes the issuer of
         any Investment Property that is Collateral, each such Loan Party (in
         such capacity, an "Issuer") agrees as follows with respect to such
         Investment Property:

                           (i) All such Investment Property issued by such
                  Issuer, all warrants, and all non-cash dividends and other
                  non-cash distributions in respect thereof at any time
                  registered in the name of, or otherwise deliverable to, any
                  Loan Party, shall be delivered directly to the Agent, for the
                  account of such Loan Party, at the Agent's address for notices
                  set forth in Section 15.8.

                           (ii) Such Issuer will not acknowledge any transfer or
                  encumbrance in respect of such Investment Property to or in
                  favor of any Person other than the Agent or a Person
                  designated by the Agent in writing.

                           (iii) With respect to any of such Investment Property
                  at any time constituting an uncertificated security as defined
                  by the UCC, the Issuer will comply with instructions
                  originated by the Agent without further consent by the
                  registered owner thereof.

         Section 6.3 Location of Collateral. Each Loan Party represents and
warrants to the Agent and the Lenders that: Schedule 6.3 is a correct and
complete list of such Loan Party's chief executive office, the location of its
books and records, the locations of the Collateral which is located within the
United States (other than Rig Materials and Supplies which in the ordinary
course of business are located at drilling locations) and the locations of all
of its other places of business. Each Loan Party covenants and agrees that it
will not (i) maintain any Collateral at any location other than those locations
listed for such Loan Party on Schedule 6.3 (other than Rig Materials and
Supplies which in the ordinary course of business are located at drilling
locations), (ii) otherwise change or add to any of such locations or (iii)
change the location of its chief executive office from the location identified
in Schedule 6.3, unless it gives the Agent at least thirty (30) days' prior
written notice

thereof and executes any and all financing statements and other documents that
the Agent requests in connection therewith. Without limiting the foregoing, each
Loan Party represents that all of its Inventory (other than Inventory in
transit) is, and covenants that all of its Inventory will be, located either (a)
on premises owned by such Loan Party, (b) on premises leased by such Loan Party
provided that the Agent has, if requested by the Agent in its sole discretion,
received an executed landlord waiver from the landlord of such premises in form
and substance satisfactory to the Agent, (c) in a warehouse or with a bailee,
provided that the Agent has, if requested by the Agent in its sole discretion,
received an executed bailee letter from the applicable Person in form and
substance satisfactory to the Agent or (d) on site at drilling locations in the
ordinary course of business.

         Section 6.4 Title to, Liens on, and Sale and Use of Collateral. Each
Loan Party represents and warrants to the Agent and the Lenders and agrees with
the Agent and the Lenders that: (a) all of the Collateral is and will continue
to be owned by such Loan Party free and clear of all Liens whatsoever, except
for Permitted Liens; (b) the Agent's Liens in the Collateral will not be subject
to any prior Lien; (c) such Loan Party will use, store, and maintain the
Collateral with all reasonable care and will use such Collateral for lawful
purposes only; and (d) such Loan Party will not, without the Agent's prior
written approval, sell, or dispose of or permit the sale or disposition of any
of the Collateral except for sales of Inventory in the ordinary course of
business and sales of Equipment as permitted by Section 6.11. The inclusion of
proceeds in the Collateral shall not be deemed to constitute the Agent's or any
Lender's consent to any sale or other disposition of the Collateral except as
expressly permitted herein.

         Section 6.5 Appraisals. Whenever a Default or Event of Default exists,
and at such other times not more frequently than one time per calendar year as
the Agent requests, the Loan Parties shall, at their expense and upon the
Agent's request, provide the Agent with appraisals or updates thereof of any or
all of the Collateral from an appraiser, and prepared on a basis, satisfactory
to the Agent, such appraisals and updates to include, without limitation,
information required by applicable law and regulation and by the internal
policies of the Lenders.

         Section 6.6 Access and Examination; Confidentiality.

                  (a) The Agent, accompanied by any Lender which so elects, may
         at all reasonable times during regular business hours (and at any time
         when a Default or Event of Default exists and is continuing) have
         access to, examine, audit, make extracts from or copies of and inspect
         any or all of the Loan Parties' records, files, and books of account
         and the Collateral, and discuss the Loan Parties' affairs with the Loan
         Parties' officers and management. The Loan Parties will deliver to the
         Agent any instrument necessary for the Agent to obtain records from any
         service bureau maintaining records for the Loan Parties. The Agent may,
         and at the direction of the Majority Lenders shall, at any time when a
         Default or Event of Default exists, and at the Loan Parties' expense,
         make copies of all of the Loan Parties' books and records, or require
         the Loan Parties to deliver such copies to the Agent. The Agent may,
         without expense to the Agent, use such of the Loan Parties' respective
         personnel, supplies, and premises as may be reasonably necessary for
         maintaining or enforcing the Agent's Liens. The Agent shall have the
         right, at any time, in the Agent's name or in the name of a nominee of

         the Agent, to verify the validity, amount or any other matter relating
         to the Accounts, Inventory, or other Collateral, by mail, telephone, or
         otherwise.

                  (b) The Loan Parties agree that, subject to their prior
         consent for uses other than in a traditional tombstone, which consent
         shall not be unreasonably withheld or delayed, the Agent and each
         Lender may use any Parent's name in advertising and promotional
         material and in conjunction therewith disclose the general terms of
         this Agreement. The Agent and each Lender severally agree to take
         normal and reasonable precautions and exercise due care to maintain the
         confidentiality of all information identified as "confidential" or
         "secret" by any Loan Party and provided to the Agent or such Lender by
         or on behalf of such Loan Party, under this Agreement or any other Loan
         Document, except to the extent that such information (i) was or becomes
         generally available to the public other than as a result of disclosure
         by the Agent or such Lender, or (ii) was or becomes available on a
         nonconfidential basis from a source other than the Loan Parties,
         provided that such source is not bound by a confidentiality agreement
         with the Loan Parties known to the Agent or such Lender; provided,
         however, that the Agent and any Lender may disclose such information
         (1) at the request or pursuant to any requirement of any Governmental
         Authority to which the Agent or such Lender is subject or in connection
         with an examination of the Agent or such Lender by any such
         Governmental Authority; (2) pursuant to subpoena or other court
         process; (3) when required to do so in accordance with the provisions

         but not limited to, any bankruptcy proceeding) to which the Agent, any
         Lender or their respective Affiliates may be party; (5) to the extent
         reasonably required in connection with the exercise of any remedy
         hereunder or under any other Loan Document; (6) to the Agent's or such
         Lender's independent auditors, accountants, attorneys and other
         professional advisors; (7) to any prospective Participant or Assignee
         under any Assignment and Acceptance, actual or potential, provided that
         such prospective Participant or Assignee agrees to keep such
         information confidential to the same extent required of the Agent and
         the Lenders hereunder; (8) as expressly permitted under the terms of
         any other document or agreement regarding confidentiality to which any
         Loan Party is party or is deemed party with the Agent or such Lender,
         and (9) to its Affiliates.

                  (b) The Loan Party shall not redate any invoice or sale or
         make sales on extended dating beyond that customary in the Loan Party's
         business or extend or modify any Account. If the Loan Party becomes
         aware of any matter adversely affecting the collectibility of any
         Account or Account Debtor involving an amount greater than $500,000,
         including information regarding the Account Debtor's creditworthiness,
         the Loan Party will promptly so advise the Agent.

                  (c) The Loan Party shall not accept any note or other
         instrument (except a check or other instrument for the immediate
         payment of money) with respect to any Account without the Agent's
         written consent. If the Agent consents to the acceptance of any such
         instrument, it shall be considered as evidence of the Account and not
         payment thereof and the

LOAN AND SECURITY AGREEMENT - Page 64

<PAGE>   72

         Loan Party will promptly deliver such instrument to the Agent, endorsed
         by the Loan Party to the Agent in a manner satisfactory in form and
         substance to the Agent. Regardless of the form of presentment, demand,
         notice of protest with respect thereto, the Loan Party shall remain
         liable thereon until such instrument is paid in full.

                  (d) The Loan Party shall notify the Agent promptly of all
         disputes and claims in excess of $500,000 with any Account Debtor, and
         agrees to settle, contest, or adjust such dispute or claim at no
         expense to the Agent or any Lender. No discount, credit or allowance
         shall be granted to any such Account Debtor without the Agent's prior
         written consent, except for discounts, credits and allowances made or
         given in the ordinary course of the Loan Party's business when no Event
         of Default exists hereunder. The Agent may, and at the direction of the
         Majority Lenders shall, at all times when an Event of Default exists
         hereunder, settle or adjust disputes and claims directly with Account
         Debtors of any Loan Party for amounts and upon terms which the Agent or
         the Majority Lenders, as applicable, shall consider advisable and, in
         all cases with respect to a Borrower, the Agent will credit the
         Borrowers' Loan Account with only the net amounts received by the Agent
         in payment of any Accounts.

                  (e) If an Account Debtor returns any Inventory to the Loan
         Party when no Event of Default exists, then the Loan Party shall
         promptly determine the reason for such return and shall issue a credit
         memorandum to the Account Debtor in the appropriate amount. In the
         event any Account Debtor returns Inventory to the Loan Party when an
         Event of Default exists, the Loan Party, upon request of the Agent,
         shall: (i) hold the returned Inventory in trust for the Agent; (ii)
         segregate all returned Inventory from all of its other property; (iii)
         dispose of the returned Inventory solely according to the Agent's
         written instructions; and (iv) not issue any credits or allowances with
         respect thereto without the Agent's prior written consent. All returned
         Inventory shall be subject to the Agent's Liens thereon. Whenever any
         Inventory is returned, the related Account shall be deemed ineligible
         to the extent of the amount owing by the Account Debtor with respect to
         such returned Inventory.

         Section 6.9 Collection of Accounts; Payments.

                  (a) Until the Agent notifies the Loan Parties to the contrary,
         the Loan Parties shall make collection of all Accounts and other
         Collateral for the Agent, shall receive all payments as the Agent's
         trustee, and shall immediately deliver all payments in their original
         form duly endorsed in blank into a Payment Account established for the
         account of the Loan Parties at a Clearing Bank acceptable to the Agent,
         subject to a Blocked Account Agreement. If the Agent requests, the Loan
         Parties shall establish a lock-box service for collections of Accounts
         at a Clearing Bank acceptable to the Agent and subject to a Blocked
         Account Agreement and other documentation acceptable to the Agent. If
         such lock-box service is established, the Loan Parties shall instruct
         all Account Debtors to make all payments directly to the address
         established for such service. If, notwithstanding such instructions,
         any Loan Party receives any proceeds of Accounts, it shall receive such
         payments as the Agent's trustee, and shall immediately deliver such
         payments to the Agent in their original form duly endorsed in blank or
         deposit them into a Payment Account, as the Agent may direct. All
         collections received

LOAN AND SECURITY AGREEMENT - Page 65

<PAGE>   73

         in any lock-box or Payment Account or directly by any Loan Party or the
         Agent, and all funds in any Payment Account or other account to which
         such collections are deposited shall be subject to the Agent's sole
         control and withdrawals by any Loan Party shall not be permitted.
         Notwithstanding the foregoing, unless and until the Loan Parties are
         notified by the Agent to the contrary, the Borrowers may retain
         payments of Foreign Currency Reimbursements for use in the ordinary
         course of business. The Agent or the Agent's designee may, at any time
         after the occurrence of an Event of Default, notify Account Debtors
         that the Accounts have been assigned to the Agent and of the Agent's
         security interest therein, and may collect them directly and charge the
         collection costs and expenses to the Loan Account as a Revolving Loan.
         So long as an Event of Default has occurred and is continuing, the Loan
         Parties, at the Agent's request, shall execute and deliver to the Agent
         such documents as the Agent shall require to grant the Agent access to
         any post office box in which collections of Accounts are received.

                  (b) If sales of Inventory are made or services are rendered by
         any Loan Party for cash, such Loan Party shall immediately deliver, or
         cause to be delivered to the Agent or deposit into a Payment Account
         the cash which such Loan Party receives.

                  (c) All payments, including immediately available funds
         received by the Agent at a bank designated by it, whether or not
         received by the Agent on account of Accounts or as proceeds of other
         Collateral will be the Agent's sole property for its benefit and the
         benefit of the Lenders and will be credited to the Loan Account
         (conditional upon final collection) after allowing one (1) Business Day
         for collection; provided, however, that such payments shall be deemed
         to be credited to the Loan Account immediately upon receipt for
         purposes of (i) determining Availability, (ii) calculating the Unused
         Line Fee pursuant to Section 3.4, and (iii) calculating the amount of
         interest accrued thereon solely for purposes of determining the amount
         of interest to be distributed by the Agent to the Lenders (but not the
         amount of interest payable by the Borrowers).

                  (d) In the event all of the Obligations are repaid upon the
         termination of this Agreement or upon acceleration of the Obligations,
         other than through the Agent's receipt of payments on account of the
         Accounts or proceeds of the other Collateral, such payment will be
         credited (conditional upon final collection) to the Borrowers' Loan
         Account one (1) Business Day after the Agent's receipt of such funds.

         Section 6.10 Inventory. Each Loan Party represents and warrants to the
Agent and the Lenders and agrees with the Agent and the Lenders that all of the
Inventory owned by such Loan Party is and will be held for use and consumption
in connection with the rendition of services in the ordinary course of such Loan
Party's business, and is and will be fit for such purposes. Each Loan Party will
keep its Inventory in good and usable condition, at its own expense. The Loan
Parties will conduct a physical count of the Inventory at least once per Fiscal
Year, and after and during the continuation of an Event of Default, at such
other times as the Agent requests. The Loan Parties will not, without the
Agent's written consent, sell any Inventory on a bill-and-hold, guaranteed sale,
sale and return, sale on approval, consignment, or other repurchase or return
basis.

         Section 6.11 Rig Equipment.

                  (a) Each Loan Party represents and warrants to the Agent and
         the Lenders and agrees with the Agent and the Lenders that all of the
         Rig Equipment owned by such Loan Party is and will be used or held for
         use in such Loan Party's business, and is and will be fit for such
         purposes. Each Loan Party shall keep and maintain its Rig Equipment in
         good operating condition and repair (ordinary wear and tear excepted)
         and shall make all necessary replacements thereof.

                  (b) The Loan Parties shall not permit any Rig Equipment to
         become a fixture with respect to real property or to become an
         accession with respect to other personal property with respect to which
         real or personal property the Agent does not have a Lien. The Loan
         Parties will not, without the Agent's prior written consent, alter or
         remove any identifying symbol or number on any Rig Equipment consisting
         of Collateral.

                  (c) The Loan Parties shall not, without the Agent's prior
         written consent, sell, lease as a lessor, or otherwise dispose of any
         Rig Equipment.

         Section 6.12 Reserved.

         Section 6.13 Documents, Instruments, and Chattel Paper. Each Loan
Party represents and warrants to the Agent and the Lenders that (a) all
documents, instruments, and chattel paper of such Loan Party describing,
evidencing, or constituting Collateral, and all signatures and endorsements
thereon, are and will be complete, valid, and genuine, and (b) all goods
evidenced by such documents, instruments, and chattel paper are and will be
owned by such Loan Party, free and clear of all Liens other than Permitted
Liens.

         Section 6.14 Right to Cure. The Agent may, in its discretion, and
shall, at the direction of the Majority Lenders, pay any amount or do any act
required of any Loan Party hereunder or under any other Loan Document in order
to preserve, protect, maintain or enforce the Obligations, the Collateral or the
Agent's Liens therein, and which any Loan Party fails to pay or do, including
payment of any judgment against any Loan Party, any insurance premium, any
warehouse charge, any finishing or processing charge, any landlord's or bailee's
claim, and any other Lien upon or with respect to the Collateral. All payments
that the Agent makes under this Section 6.14 and all out-of-pocket costs and
expenses that the Agent pays or incurs in connection with any action taken by it
hereunder shall be charged to the Borrowers' Loan Account as a Revolving Loan.
Any payment made or other action taken by the Agent under this Section 6.14
shall be without prejudice to any right to assert an Event of Default hereunder
and to proceed thereafter as herein provided.

         Section 6.15 Power of Attorney. Each Loan Party, as to itself, hereby
appoints the Agent and the Agent's designee as its attorney, with power: (a) to
endorse such Loan Party's name on any checks, notes, acceptances, money orders,
or other forms of payment or security that come into the Agent's or any Lender's
possession; (b) in connection with the Collateral, to sign such Loan Party's
name on any financing statements and other public records and to file any such
financing statements by electronic means with or without a signature as
authorized or required by applicable law or filing

LOAN AND SECURITY AGREEMENT - Page 67

procedure; (c) so long as any Event of Default has occurred and is continuing,
to sign such Loan Party's name on any invoice, bill of lading, warehouse receipt
or other document of title relating to any Collateral, on drafts against
customers, on assignments of Accounts or on notices of assignment, and to notify
the post office authorities to change the address for delivery of such Loan
Party's mail to an address designated by the Agent and to receive, open and
dispose of all mail addressed to such Loan Party; (d) to send requests for
verification of Accounts to customers or Account Debtors; (e) to clear Inventory
through customs in such Loan Party's name, the Agent's name or the name of the
Agent's designee, and to sign and deliver to customs officials powers of
attorney in such Loan Party's name for such purpose; and (f) to do all things
necessary to carry out this Agreement. Each Loan Party ratifies and approves all
acts of such attorney. None of the Lenders or the Agent nor their attorneys will
be liable for any acts or omissions or for any error of judgment or mistake of
fact or law. This power, being coupled with an interest, is irrevocable until
this Agreement has been terminated and the Obligations have been fully
satisfied.

         Section 6.16 The Agent's and Lenders' Rights, Duties and Liabilities.
The Loan Parties assume all responsibility and liability arising from or
relating to the use, sale or other disposition of the Collateral. The
Obligations shall not be affected by any failure of the Agent or any Lender to
take any steps to perfect the Agent's Liens or to collect or realize upon the
Collateral, nor shall loss of or damage to the Collateral release any Loan Party
from any of the Obligations. Following the occurrence and continuation of an
Event of Default, the Agent may (but shall not be required to), and at the
direction of the Majority Lenders shall, without notice to or consent from any
Loan Party, sue upon or otherwise collect, extend the time for payment of,
modify or amend the terms of, compromise or settle for cash, credit, or
otherwise upon any terms, grant other indulgences, extensions, renewals,
compositions, or releases, and take or omit to take any other action with
respect to the Collateral, any security therefor, any agreement relating
thereto, any insurance applicable thereto, or any Person liable directly or
indirectly in connection with any of the foregoing, without discharging or
otherwise affecting the liability of any Loan Party for the Obligations or under
this Agreement or any other agreement now or hereafter existing between the
Agent and/or any Lender and any Loan Party.

         Section 6.17 Site Visits, Observations and Testing. The Agent and its
representatives will have the right at any reasonable time to enter and visit
the Premises and any other place where any property of any Loan Party is located
for the purposes of observing the Premises, taking and removing soil or
groundwater samples, and conducting tests on any part of the Premises. The Agent
is under no duty, however, to visit or observe the Premises or to conduct tests,
and any such acts by the Agent will be solely for the purposes of protecting the
Agent's Liens and preserving the Agent and the Lenders' rights under this
Agreement. No site visit, observation or testing by the Agent and the Lenders
will result in a waiver of any Default or Event of Default or impose any
liability on the Agent or the Lenders. In no event will any site visit,
observation or testing by the Agent be a representation that hazardous
substances are or are not present in, on or under the Premises, or that there
has been or will be compliance with any Environmental Law. Neither any Loan
Party nor any other party is entitled to rely on any site visit, observation or
testing by the Agent. The Agent and the Lenders owe no duty of care to protect
the Loan Parties or any other party against, or to inform the Loan Parties or
any other party of, any hazardous substances or any other adverse condition
affecting the Premises. The Agent may in its discretion disclose to the Loan
Parties or to any other party if so required by law any report or findings made
as a result of, or in connection with, any site

LOAN AND SECURITY AGREEMENT - Page 68

<PAGE>   76

visit, observation or testing by the Agent. The Loan Parties understand and
agree that the Agent makes no warranty or representation to the Loan Parties or
any other party regarding the truth, accuracy or completeness of any such report
or findings that may be disclosed. The Loan Parties also understand that
depending on the results of any site visit, observation or testing by the Agent
and disclosed to the Loan Parties, the Loan Parties may have a legal obligation
to notify one or more environmental agencies of the results, that such reporting
requirements are site-specific, and are to be evaluated by the Loan Parties
without advice or assistance from the Agent. In each instance, the Agent will
give the Loan Parties reasonable notice before entering the Premises or any
other place the Agent is permitted to enter under this Section 6.17. The Agent
will make reasonable efforts to avoid interfering with the Loan Parties' use of
the Premises or any other property in exercising any rights provided hereunder.

         Section 6.18 Guaranties; Loan Party Joinder. Each Loan Party shall
guarantee payment and performance of the Obligations (other than Obligations
owing by itself in a case where such guaranteeing Loan Party is a Borrower and
excluding Existing Obligations in the case of any such guarantee by a Newly
Obligated Party)) pursuant to a Guaranty Agreement, in form and substance
satisfactory to the Agent, duly executed by each such Loan Party. Each such
guaranteeing Loan Party that is a Borrower acknowledges and expressly agrees
with the Agent and each Lender that the Guaranty by such Borrower is required
solely as a condition to, and is given solely as inducement for and in
consideration of, credit or accommodations extended or to be extended under the
Loan Documents to any or all of the other Loan Parties and is not required or
given as a condition to extensions of credit to such Borrower. Promptly upon
creation or acquisition of any Restricted Subsidiary, such Loan Party shall
cause such Restricted Subsidiary to become a Loan Party (but unless otherwise
agreed by the Agent and the Lenders, not as a Borrower) and guarantee the
Obligations by executing and delivering to the Agent such Loan Documents and
other instruments, certificates, and agreements, in each case in form and
substance satisfactory to the Agent, as the Agent may request. Upon execution
and delivery of such Loan Documents and other instruments, certificates, and
agreements, such newly created or acquired Restricted Subsidiary shall
automatically become a Loan Party and thereupon shall have all of the rights,
benefits, duties, and obligations of a Loan Party under the Loan Documents.

         Section 6.19 Voting Rights, Distributions, Etc. in Respect of
Investment Property.

                  (a) So long as no Event of Default shall have occurred and be
         continuing (i) each Loan Party shall be entitled to exercise any and
         all voting and other consensual rights (including, without limitation,
         the right to give consents, waivers, and notifications in respect of
         any securities) pertaining to its Investment Property or any part
         thereof; provided, however, that without the prior written consent of
         the Agent and the Majority Lenders, no vote shall be cast or consent,
         waiver, or ratification given or action taken which would (A) be
         inconsistent with or violate any provision of this Agreement or any
         other Loan Document or (B) amend, modify, or waive any material term,
         provision, or condition of the certificate of incorporation, bylaws,
         certificate of formation, or other charter document or other agreement
         relating to, evidencing, providing for the issuance of, or securing any
         such Investment Property, in any manner that would impair such
         Investment Property, the transferability thereof, or the Agent's Liens
         therein, and (ii) each Loan Party shall be entitled to receive and

LOAN AND SECURITY AGREEMENT - Page 69

<PAGE>   77

         retain any and all dividends and interest paid in respect of any of
         such Investment Property (unless otherwise required by this Agreement).

                  (b) Upon the occurrence and during the continuance of an Event
         of Default, (i) the Agent may, without notice to any Loan Party,
         transfer or register in the name of the Agent or any of its nominees,
         for the ratable benefit of the Agent and the Lenders, any or all of the
         Collateral consisting of Investment Property, the proceeds thereof (in
         cash or otherwise), and all liens, security, rights, remedies, and
         claims of any Loan Party with respect thereto (as used in this Section
         6.19 collectively, the "Pledged Collateral") held by the Agent
         hereunder, and the Agent or its nominee may thereafter, after delivery
         of notice to the applicable Loan Party, exercise all voting and
         corporate rights at any meeting of any corporation, partnership, or
         other business entity issuing any of the Pledged Collateral and any and
         all rights of conversion, exchange, subscription, or any other rights,
         privileges, or options pertaining to any of the Pledged Collateral as
         if it were the absolute owner thereof, including, without limitation,
         the right to exchange at its discretion any and all of the Pledged
         Collateral upon the merger, consolidation, reorganization,
         recapitalization, or other readjustment of any corporation,
         partnership, or other business entity issuing any of such Pledged
         Collateral or upon the exercise by any such issuer or the Agent of any
         right, privilege, or option pertaining to any of the Pledged
         Collateral, and in connection therewith, to deposit and deliver any and
         all of the Pledged Collateral with any committee, depositary, transfer
         agent, registrar, or other designated agency upon such terms and
         conditions as it may determine, all without liability except to account
         for property actually received by it, but the Agent shall have no duty
         to exercise any of the aforesaid rights, privileges, or options, and
         the Agent shall not be responsible for any failure to do so or delay in
         so doing, (ii) after the Agent's giving of the notice specified in
         clause (i) of this Section 6.19(b), all rights of any Loan Party to
         exercise the voting and other consensual rights which it would
         otherwise be entitled to exercise pursuant to Section 6.19(a)(i) shall
         be suspended until such Event of Default shall no longer exist, and all
         such rights shall, until such Event of Default shall no longer exist,
         thereupon become vested in the Agent which shall thereupon have the
         sole right to exercise such voting and other consensual rights, and
         (iii) each Loan Party shall execute and deliver (or cause to be
         executed and delivered) to the Agent all such proxies and other
         instruments as the Agent may reasonably request for the purpose of
         enabling the Agent to exercise the voting and other rights which it is
         entitled to exercise pursuant to this Section 6.19(b). The foregoing
         shall not in any way limit the Agent's power and authority granted
         pursuant to Section 6.15.

                                   ARTICLE 7

               BOOKS AND RECORDS; FINANCIAL INFORMATION; NOTICES

         Section 7.1 Books and Records. The Loan Parties shall maintain, at all
times, correct and complete books, records and accounts in which complete,
correct and timely entries are made of their respective transactions in
accordance with GAAP applied consistently with the audited Financial Statements
required to be delivered pursuant to Section 7.2(a). The Loan Parties shall, by
means of appropriate entries, reflect in such accounts and in all Financial
Statements proper liabilities and reserves for all taxes and proper provision
for depreciation and amortization of property and bad

LOAN AND SECURITY AGREEMENT - Page 70

<PAGE>   78

debts, all in accordance with GAAP. The Loan Parties shall maintain at all times
books and records pertaining to the Collateral in such detail, form and scope as
the Agent or any Lender shall reasonably require, including, but not limited to,
records of (a) all payments received and all credits and extensions granted with
respect to the Accounts; (b) the return, rejections, repossession, stoppage in
transit, loss, damage, or destruction of any Inventory; and (c) all other
dealings affecting the Collateral.

         Section 7.2 Financial Information. The Loan Parties shall promptly
furnish to each Lender, all such financial information as the Agent or any
Lender shall reasonably request, and notify its auditors and accountants that
the Agent, on behalf of the Lenders, is authorized to obtain such information
directly from them. Without limiting the foregoing, the Loan Parties will
furnish, or cause to be furnished, to the Agent, in sufficient copies for
distribution by the Agent to each Lender, in such detail as the Agent or the
Lenders shall request, the following:

                  (a) As soon as available, but in any event not later than
         ninety (90) days after the close of each Fiscal Year, consolidated
         audited and consolidating balance sheets, and statements of income and
         expense, cash flow and of stockholders' equity for the Parent and its
         consolidated Subsidiaries for such Fiscal Year, and the accompanying
         notes thereto, setting forth in each case in comparative form figures
         for the previous Fiscal Year, all in reasonable detail, fairly
         presenting the financial position and the results of operations of the
         Parent and its consolidated Subsidiaries as at the date thereof and for
         the Fiscal Year then ended, and prepared in accordance with GAAP. Such
         statements shall be examined in accordance with generally accepted
         auditing standards by and, in the case of such statements performed on
         a consolidated basis, accompanied by a report thereon unqualified as to
         scope of independent certified public accountants selected by the
         Parent and reasonably satisfactory to the Agent. Each Loan Parent
         hereby authorizes the Agent to communicate directly with its certified
         public accountants and, by this provision, authorizes those accountants
         to disclose to the Agent any and all financial statements and other
         supporting financial documents and schedules relating to such Loan
         Party and to discuss directly with the Agent its finances and affairs.
         Each Loan Party will authorize such independent public accountants in
         writing (with a copy to the Agent) to comply with the terms of this
         Section 7.2(a).

                  (b) As soon as available, but in any event not later than
         thirty (30) days after the end of each month, consolidated and
         consolidating unaudited balance sheets of the Parent and its
         consolidated Subsidiaries as at the end of such month, and consolidated
         and consolidating unaudited statements of income and expense and cash
         flow for the Parent and its consolidated Subsidiaries for such month
         and for the period from the beginning of the Fiscal Year to the end of
         such month, all in reasonable detail, fairly presenting the financial
         position and results of operations of the Parent and its consolidated

         Each Loan Party warrants and represents to the Agent and the Lenders
that except as hereafter disclosed to and accepted by the Agent and the Majority
Lenders in writing:

         Section 8.1 Authorization, Validity, and Enforceability of this
Agreement and the Loan Documents; No Conflicts. Each Loan Party has the power
and authority to execute, deliver and perform this Agreement and the other Loan
Documents, to incur the Obligations, and to grant to the Agent Liens upon and
security interests in the Collateral. Each Loan Party has taken all necessary
action (including obtaining approval of its stockholders, partners, general
partner(s), members or other applicable equity owners, if necessary) to
authorize its execution, delivery, and performance of this Agreement and the
other Loan Documents to which it is a party. This Agreement and the other Loan
Documents have been duly executed and delivered by each Loan Party, and
constitute the legal, valid and binding obligations of each Loan Party,
enforceable against it in accordance with their respective terms without
defense, setoff or counterclaim. Each Loan Party's execution, delivery, and
performance of this Agreement and the other Loan Documents do not and will not
conflict with, or constitute a violation or breach of, or constitute a default
under, or result in the creation or imposition of any Lien upon the property of
any Loan Party or any of its Subsidiaries by reason of the terms of (a) any
contract, mortgage, Lien, lease, agreement, indenture (including, without
limitation, the Indentures), or instrument to which such Loan Party is a party
or which is binding upon it, (b) any Requirement of Law applicable to any Loan
Party or any of its Subsidiaries, or (c) the certificate or articles of
incorporation or by-laws of any Loan Party or any of its Subsidiaries. The
incurrence of "Indebtedness," as such term is defined in each of the Indentures,
respectively, resulting from each Borrowing is permitted by each of the
Indentures, respectively.

         Section 8.2 Validity and Priority of Security Interest. The provisions
of this Agreement and the other Loan Documents create legal and valid Liens on
all the Collateral in favor of the Agent, for the ratable benefit of the Agent
and the Lenders, and such Liens constitute perfected and continuing Liens on all
the Collateral, having priority over all other Liens on the Collateral, securing
all the Obligations, and enforceable against the Loan Parties and all third
parties.

         Section 8.3 Organization and Qualification. Each Loan Party (a) is
duly formed and organized and validly existing in good standing under the laws
of the state of its formation and organization, (b) is qualified to do business
as a foreign business entity and is in good standing in the jurisdictions set
forth on Schedule 8.3, which are the only jurisdictions in which qualification
is necessary in order for it to own or lease its property and conduct its
business, except where the failure to qualify would not cause a Material Adverse
Effect and (c) has all requisite power and authority to conduct its business and
to own its property.

incorporated and organized and validly existing in good standing under the laws
of its state of formation and organization set forth on Schedule 8.5, and (b)
qualified to do business as a foreign business entity and in good standing in
each jurisdiction in which the failure to so qualify or be in good standing
could reasonably be expected to have a Material Adverse Effect, and (c) has all
requisite power and authority to conduct its business and own its property.

         Fiscal Year then ended, accompanied by the report thereon of the

         required herein represent the Loan Parties' good faith estimate of the
         future financial performance of the Loan Parties and their consolidated

of in the ordinary course of business since the date thereof), free of all Liens
except Permitted Liens.

Closing Date, a correct and complete list of all Real Estate owned by each Loan
Party or any of its Subsidiaries, all leases and subleases of real or personal

         permits necessary for their current operations under Environmental
         Laws, and all such permits are in good standing and each Loan Party and
         its Subsidiaries are in compliance with all terms and conditions of
         such permits.

         is investigating its compliance with, any Environmental Laws or that it
         is or may be liable to any other Person as a result of a Release or
         threatened Release of a Contaminant.

                  (e) None of the present or past operations of any Loan Party
         or its Subsidiaries is the subject of any investigation by any

                  (h) No Loan Party nor any of its Subsidiaries has entered into

         law. Each Plan which is intended to qualify under Section 401(a) of the
         Code has received a favorable determination letter from the IRS and to
         the best knowledge of the Loan Parties, nothing has occurred which
         would cause the loss of such qualification. Each Loan Party and each
         ERISA Affiliate has made all required contributions to any Plan subject

         to occur; (ii) no Pension Plan has any Unfunded Pension Liability;
         (iii) no Loan Party nor any ERISA Affiliate has incurred, or reasonably

         Section 4007 of ERISA); (iv) no Loan Party 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 Section 4201 or 4243 of
         ERISA with respect to a Multi-employer Plan; and (v) no Loan Party nor
         any ERISA Affiliate has engaged in a transaction that could be subject

which, to the Loan Parties' knowledge are not delinquent and in the aggregate do
not exceed $100,000).

         Section 8.23 Regulated Entities. No Loan Party, nor any Person
controlling any Loan Party, is an "investment company" or a company "controlled"
by an "investment company" within the meaning of the Investment Company Act of
1940. No Loan Party is a "holding company" or a "subsidiary company" of a
"holding company" or an "affiliate" of a "holding company" or a "public utility"

subject to regulation under the Federal Power Act, the Interstate Commerce Act,
any state public utilities code or law, or any other federal or state statute or
regulation limiting its ability to incur indebtedness.

         Section 8.26 No Material Adverse Change. No material adverse change
has occurred in the Property, business, operations, or conditions (financial or
otherwise) of any Loan Party since the date of the Financial Statements
delivered to the Lenders. On the basis of a comprehensive review and assessment
undertaken by the Loan Parties of their respective computers and computer
applications and inquiry made of the Loan Party's material suppliers, vendors
and customers, each Loan Party reasonably believes that the "Year 2000 problem"
(that is, the risk that computers and computer applications used by any person
may be unable to recognize and perform properly date-sensitive functions
involving certain dates prior to and any date after December 31, 1999) will not
result in a Material Adverse Effect.

         Section 8.27 Full Disclosure. None of the representations or
warranties made by any Loan Party or any Subsidiary in the Loan Documents as of
the date such representations and warranties are made or deemed made, and none
of the statements contained in any exhibit, report, statement or certificate
furnished by or on behalf of any Loan Party or any Subsidiary in connection with
the Loan Documents (including the offering and disclosure materials delivered by
or on behalf of any Loan Party to the Lenders prior to the Closing Date),
contains any untrue statement of a material fact or omits any material fact
required to be stated therein or necessary to make the statements made therein,
in light of the circumstances under which they are made, not misleading as of
the time when made or delivered.

         Section 8.28 Material Agreements. No Loan Party nor any of its
Subsidiaries is a party to any indenture, agreement, lease or other instrument,
or subject to any charter or corporate restriction, Governmental Authority or
Requirements of Law compliance with the terms of which would reasonably be
expected to have a Materially Adverse Effect. The latest Form 10Q or Form 10K
filed by the Parent, together with those items listed on Schedule 8.28 as of the
Closing Date, discloses all material agreements and contracts to which any Loan
Party or any of its Subsidiaries is a party or is bound as of the date hereof.

accurate list of all bank accounts maintained by each Loan Party with any bank
or other financial institution.

         Section 8.30 Governmental Authorization. No approval, consent,
exemption, authorization, or other action by, or notice to, or filing with, any
Governmental Authority or other Person is necessary or required in connection
with the execution, delivery or performance by, or enforcement against, any Loan
Party or any of its Subsidiaries of this Agreement or any other Loan Document.

         Section 8.31 Investment Property.

                  (a) Schedule 8.31 sets forth a correct and complete list of
         all Investment Property owned by each Loan Party. Each such Loan Party
         is the legal and beneficial owner of such Investment Property, as so
         reflected, free and clear of any Lien (other than Permitted Liens), and
         has not sold, granted any option with respect to, assigned or
         transferred or otherwise disposed of any of its rights or interest
         therein.

         and the ownership interest of each such shareholder are as set forth on
         Schedule 8.5, and each such shareholder is the registered owner thereof
         on the books of such Issuer; (ii) such Issuer acknowledges the
         continuing security interest, collateral assignment, lien and pledge in
         favor of the Agent granted pursuant to Section 6.1; and (iii) such
         Issuer is not aware of any liens, restrictions, or adverse claims which
         exist on any such Investment Property other than the continuing
         security interest, collateral assignment, lien and pledge in favor of
         the Agent granted pursuant to Section 6.1.

         Section 8.32 Mutual Benefit. Each of the Loan Parties expects to
derive benefit (and its board of directors has determined that it may reasonably
be expected to derive benefit), directly and indirectly, from successful
operations of the Parent, each of the other Loan Parties and the Parent's
Subsidiaries. Each Loan Party expects to derive benefit (and the boards of
directors or other governing body of each such Loan Party have determined that
it may reasonably be expected to derive benefit), directly and indirectly, from
the credit extended by the Lenders to the Borrowers hereunder, both in their
separate capacities and as members of the group of companies. Each Loan Party
has determined that execution, delivery and performance of this Agreement and
any other Loan Documents to be executed by such Loan Party is within its
corporate purpose, will be of direct and indirect benefit to such Loan Party and
is in its best interest.

         Section 8.33 Loan Parties. All Loan Parties are Wholly Owned
Subsidiaries of the Parent. As of the Closing Date the Loan Parties other than
the Parent constitute all Domestic Subsidiaries, other than the Unrestricted

         Section 8.34 Non-Material Subsidiaries. None of the Subsidiaries of
the Parent listed in Schedule 9.9 has any material tangible assets or is
material to any of the operations of any of the Loan Parties.

                                    ARTICLE 9

                       AFFIRMATIVE AND NEGATIVE COVENANTS

<PAGE>   91

provided, however, so long as such Loan Party has notified the Agent in writing,
neither such Loan Party nor any of its Subsidiaries need pay any tax, fee,
assessment, or governmental charge, that (i) it is contesting in good faith by
appropriate proceedings diligently pursued, (ii) such Loan Party or its
Subsidiary, as the case may be, has established proper reserves for as provided
in GAAP, and (iii) no Lien (other than a Permitted Lien) results from such
non-payment.

         Section 9.2 Existence and Good Standing. Except with respect to any
Loan Party that merges into or consolidates with another Loan Party as allowed
by Section 9.9, each Loan Party shall, and shall cause each of its Subsidiaries
to, maintain its entity existence and its qualification and good standing in all
jurisdictions in which the failure to maintain such existence and qualification
or good standing could reasonably be expected to have a Material Adverse Effect.

         Section 9.3 Compliance with Law and Agreements; Maintenance of
Licenses. Each Loan party shall comply, and shall cause each Subsidiary to
comply, in all material respects with all Requirements of Law of any
Governmental Authority having jurisdiction over it or its business (including

franchises, and governmental authorizations necessary to own its property and to

a manner which does not adversely affect the rights of the Lenders or the Agent.

         Section 9.4 Maintenance of Property. Each Loan Party shall, and shall

         types as is customary for Persons engaged in the same or similar
         business, as the Agent, in its discretion, or acting at the direction
         of the Majority Lenders, shall specify, in amounts, and under policies
         acceptable to the Agent and the Majority Lenders. Without limiting the
         foregoing, each Loan Party shall also maintain, and shall cause each of
         its Subsidiaries to maintain, flood insurance on all Inventory and
         books and records located on any Real Estate, if any, which has been or
         hereafter is designated as "flood prone" or a "flood risk area,"

                  (b) Each Loan Party shall cause the Agent, for the ratable
         benefit of the Agent and the Lenders, to be named as secured party or
         mortgagee and sole loss payee or additional insured, on all Rig
         Equipment in a manner acceptable to the Agent. Each policy of insurance
         shall contain a clause or endorsement requiring the insurer to give not
         less than thirty (30) days' prior written notice to the Agent in the
         event of cancellation of the policy for any reason whatsoever and a
         clause or endorsement stating that the interest of the Agent shall not
         be impaired or invalidated by any act or neglect of any Loan Party or
         of its Subsidiaries or the owner of any premises for purposes more
         hazardous than are permitted by such policy. All premiums for such
         insurance shall be paid by the Loan Parties when due, and certificates
         of insurance and, if requested by the Agent or any Lender, photocopies
         of the policies, shall be delivered to the Agent, in each case in
         sufficient quantity for distribution by the Agent to each of the
         Lenders. If any Loan Party fails to procure such insurance or to pay
         the premiums therefor when due, the Agent may, and at the direction of
         the Majority Lenders shall, do so from the proceeds of Revolving Loans.

                  (c) Each Loan Party shall promptly notify the Agent and the
         Lenders of any loss, damage, or destruction to the Collateral, whether
         or not covered by insurance. The Agent is hereby authorized to collect
         all insurance proceeds in respect of Collateral directly and to apply
         or remit them as follows:

                  property other than Collateral, after deducting from such
                  proceeds the reasonable expenses, if any, incurred by the
                  Agent in the collection or handling thereof, the Agent shall
                  promptly remit to the Loan Parties such proceeds.

                           (ii) With respect to insurance proceeds relating to
                  Collateral, after deducting from such proceeds the reasonable
                  expenses, if any, incurred by the Agent in the collection or
                  handling thereof, the Agent shall apply such proceeds,
                  ratably, to the reduction of the Obligations in the manner
                  provided by Section 4.8, or at the option of the Majority
                  Lenders, may permit or require such money, or any part
                  thereof, to be used to replace, repair, restore or rebuild the
                  relevant Collateral in a diligent and expeditious manner with
                  materials and workmanship of substantially the same quality as
                  existed before the loss, damage or destruction.

         Section 9.6 Condemnation.

                  (a) Each Loan Party shall, immediately upon learning of the
         institution of any proceeding for the condemnation or other taking of
         any of its property, notify the Agent of the pendency of such
         proceeding, and agrees that the Agent may participate in any such
         proceeding, and the Loan Parties from time to time will deliver to the
         Agent all instruments reasonably requested by the Agent to permit such
         participation.

                  (b) The Agent is hereby authorized to collect the proceeds of
         any condemnation claim or award directly, and to apply or remit them as
         follows:

LOAN AND SECURITY AGREEMENT - Page 85

<PAGE>   93

                           (i) With respect to condemnation proceeds relating to
                  property other than Collateral, after deducting from such
                  proceeds the reasonable expenses, if any, incurred by the
                  Agent in the collection or handling thereof, the Agent shall
                  remit to the Loan Parties such proceeds.

                           (ii) With respect to condemnation proceeds relating
                  to Collateral, after deducting from such proceeds the
                  reasonable expenses, if any, incurred by the Agent in the
                  collection or handling thereof, the Agent shall apply such
                  proceeds, ratably, to the reduction of the Obligations in the
                  order provided for in Section 4.8.

         Section 9.7 Environmental Laws.

                  (a) Each Loan Party shall, and shall cause each of its
         Subsidiaries to, conduct its business in compliance with all
         Environmental Laws applicable to it, including those relating to the
         generation, handling, use, storage, and disposal of any Contaminant.
         Each Loan Party shall, and shall cause each of its Subsidiaries to,
         take prompt and appropriate action to respond to any non-compliance
         with Environmental Laws and shall regularly report to the Agent on such
         response.

                  (b) Without limiting the generality of the foregoing, the Loan
         Parties shall submit to the Agent and the Lenders annually, commencing
         on the first Anniversary Date, and on each Anniversary Date thereafter,

         issue. The Agent or any Lender may request copies of technical reports
         prepared by any Loan Party and its communications with any Governmental
         Authority to determine whether such Loan Party or any of its
         Subsidiaries is proceeding reasonably to correct, cure or contest in
         good faith any alleged non-compliance or environmental liability. Each
         Loan Party shall, at the Agent's or the Majority Lenders' request and
         at the Loan Party's expense, (i) retain an independent environmental
         engineer acceptable to the Agent to evaluate the site, including tests
         if appropriate, where the non-compliance or alleged non-compliance with
         Environmental Laws has occurred and prepare and deliver to the Agent,
         in sufficient quantity for distribution by the Agent to the Lenders, a
         report setting forth the results of such evaluation, a proposed plan
         for responding to any environmental problems described therein, and an
         estimate of the costs thereof, and (ii) provide to the Agent and the
         Lenders a supplemental report of such engineer whenever the scope of
         the environmental problems, or the response thereto or the estimated
         costs thereof, shall change in any material respect.

         Section 9.8 Compliance with ERISA. Each Loan Party shall, and shall
cause each of its ERISA Affiliates to: (a) maintain each Plan in compliance in

         Inc., a Wholly-Owned Subsidiary of the Parent.

The acceptance by the Borrower of any Loans made or Letters of Credit issued on
the Closing Date shall be deemed to be a representation and warranty made by the
Loan Parties to the effect that all of the conditions precedent to the making of
such Loans or the issuance of such Letters of Credit have been satisfied, with
the same effect as delivery to the Agent and the Lenders of a certificate signed
by a Responsible Officer of the Loan Parties, dated the Closing Date, to such
effect. Execution and delivery to the Agent by a Lender of a counterpart of this
Agreement shall be deemed confirmation by such Lender that (i) all conditions
precedent in this Section 10.1 have been fulfilled to the satisfaction of such
Lender and (ii) the decision of such Lender to execute and deliver to the Agent
an executed counterpart of this Agreement was made by such Lender independently
and without reliance on the Agent or any other Lender as to the satisfaction of
any condition precedent set forth in this Section 10.1.

         Section 10.2 Conditions Precedent to Each Loan. The obligation of the
Lenders to make each Loan, including the initial Revolving Loans on the Closing
Date and the obligation of the Agent to issue or cause to be issued or to
provide Credit Support for any Letter of Credit shall be subject to the further
conditions precedent that on and as of the date of any such extension of credit:

                  (a) the following statements shall be true, and the acceptance
         by the Borrowers of any extension of credit shall be deemed to be a
         statement to the effect set forth in clauses (i) and (ii), with the
         same effect as the delivery to the Agent and the Lenders of a
         certificate signed by a Responsible Officer of each Loan Party, dated
         the date of such extension of credit, stating that:

                           (i) The representations and warranties contained in
                  this Agreement and the other Loan Documents are correct in all
                  material respects on and as of the date of such extension of
                  credit as though made on and as of such date, other than any
                  such representation or warranty which relates to a specified
                  prior date and except to the extent the Agent and the Lenders
                  have been notified by the Loan Parties that any representation
                  or warranty is not correct and the Majority Lenders have
                  explicitly waived in writing compliance with such
                  representation or warranty; and

                           (ii) No event has occurred and is continuing, or
                  would result from such extension of credit, which constitutes
                  a Default or an Event of Default;

                  (b) The amount of the Borrowing Base shall be sufficient to
         make such Revolving Loans or issue such Letters of Credit without
         exceeding the Availability, provided, however, that the foregoing
         conditions precedent are not conditions to each Lender participating in
         or reimbursing the Bank or the Agent for such Lenders' Pro Rata Share
         of any Non-Ratable Loan or Agent Advance made in accordance with the
         provisions of in Sections 2.2(h), (i) and (j);

                  (c) The Agent shall have received satisfactory evidence that
         the Agent has a valid, exclusive (other than Permitted Liens) and
         perfected first priority security interest, lien, collateral assignment
         and pledge as of such date in all Collateral and other property, if
         any, covered by the Agent Lien;

                  (d) Except as disclosed in writing to the Agent and the
         Lenders on or before the Closing Date, as of the Closing Date and as of
         the date of funding such Loan or issuing such Letter of Credit, there
         shall not have occurred any change which is materially adverse, in the
         Agent's or the Lenders' discretion, to the assets, liabilities,
         businesses, operations, or condition (financial or otherwise) of the
         Loan Parties in comparison to such conditions as presented by the
         Financial Statements and no Material Adverse Effect shall have
         occurred.

         amount owing hereunder when due, whether upon demand or otherwise;

                  (b) any representation or warranty made or deemed made by the

         any Financial Statement, or any certificate furnished by the Loan
         Parties or any of their Subsidiaries at any time to the Agent or any
         Lender shall prove to be untrue in any material respect as of the date
         on which made, deemed made, or furnished;

                  (c) any default shall occur in

                           (i) the observance or performance of any of the
                  covenants and agreements contained in Articles 6 or 7 or
                  Sections 9.2 (insofar as it requires the preservation of the
                  existence of the Loan Parties), 9.9 through 9.15 and 9.19
                  through 9.28, or

                           (ii) the observance or performance of any of the
                  covenants and agreements contained in this Agreement, other
                  than as referenced in Sections 11.1(a) and 11.1(c)(i) of this
                  Agreement, or any other Loan Documents, or any other agreement
                  entered into at any time to which the Loan Parties or any
                  Subsidiary and the Agent or any Lender are party (including in
                  respect of any Bank Products) and such default shall continue
                  for a period of thirty (30) days after written notice thereof
                  has been given to Parent by the Agent, or if any such
                  agreement or document shall terminate (other than in
                  accordance with its terms or the terms hereof or with the
                  written consent of the Agent and the Majority Lenders) or

         Subsidiaries, and such default shall continue for more than the period
         of grace, if any, therein specified, if the effect thereof (with or
         without the giving of notice or further lapse of time or both) is to
         accelerate, or to permit the holders of any such Debt For Borrowed
         Money to accelerate, the maturity of any such Debt For Borrowed Money;
         or any such Debt For Borrowed Money shall be declared due and payable

         monitor, trustee or similar officer for any Loan Party or any of its
         Restricted Subsidiaries or for all or any part of its property shall be
         appointed or a warrant of attachment, execution or similar process
         shall be issued against any part of the property of any Loan Party or
         any of its Restricted Subsidiaries;

                  (h) any Loan Party or any of its Restricted Subsidiaries shall
         file a certificate of dissolution under applicable state law or shall
         be liquidated, dissolved or wound-up (except in a transaction allowed
         by Section 9.9) or shall commence or have commenced against it any
         action or proceeding for dissolution, winding-up or liquidation, or

         thirty (30) days after the entry thereof;

                  (l) any loss, theft, damage or destruction of any item or
         items of Collateral or other property of any Loan Party or any
         Restricted Subsidiary occurs which materially and adversely affects the
         property, business, operation, prospects, or condition of any Loan

                  (s) an "Event of Default" (as defined in the Indenture 1997)
         occurs under the Indenture 1997 prior to the discharge thereof; or

                  (t) an "Event of Default" (as defined in the Indenture 1998)
         occurs under the Indenture 1998 prior to the discharge thereof.

         Section 11.2 Remedies.

                  (a) If a Default or an Event of Default exists, the Agent may,
         in its discretion, and shall, at the direction of the Majority Lenders,
         do one or more of the following at any time or times and in any order,
         without notice to or demand on any Loan Party: (i) reduce the Maximum
         Revolver Amount, or the advance rates against Eligible Accounts and/or
         Approved Foreign Accounts used in computing the Borrowing Base, or
         reduce one or more of the other elements used in computing the
         Borrowing Base; (ii) restrict the amount of or refuse to make Revolving
         Loans; and (iii) restrict or refuse to provide Letters of Credit or
         Credit Support. If an Event of Default exists, the Agent shall, at the
         direction of the Majority Lenders, do one or more of the following, in
         addition to the actions described in the preceding sentence, at any
         time or times and in any order, without notice to or demand on any Loan
         Party: (A) terminate the Commitments and this Agreement; (B) declare
         any or all Obligations to be immediately due and payable; provided,
         however, that upon the occurrence of any Event of Default described in
         Sections 11.1(e), 11.1(f), 11.1(g), or 11.1(h), the Commitments shall
         automatically and immediately expire and all Obligations shall
         automatically become immediately due and payable without notice or
         demand of any kind; and (C) pursue its other rights and remedies under
         the Loan Documents and applicable law.

                  (b) If an Event of Default has occurred and is continuing: (i)
         the Agent shall have for the benefit of the Lenders, in addition to all
         other rights of the Agent and the Lenders, the rights and remedies of a
         secured party under the UCC; (ii) the Agent may, at any time, take
         possession of the Collateral and keep it on any Loan Party's premises,
         at no cost to the Agent or any Lender, or remove any part of it to such
         other place or places as the Agent may desire, or any Loan Party shall,
         upon the Agent's demand, at any Loan Party's cost, assemble the
         Collateral and make it available to the Agent at a place reasonably
         convenient to the Agent; and (iii) the Agent may sell and deliver any
         Collateral at public or private sales, for cash, upon credit or
         otherwise, at such prices and upon such terms as the Agent deems
         advisable, in its sole discretion, and may, if the Agent deems it
         reasonable, postpone or adjourn any sale of the Collateral by an
         announcement at the time and place of sale or of such postponed or

LOAN AND SECURITY AGREEMENT - Page 98

<PAGE>   106

         adjourned sale without giving a new notice of sale. Without in any way
         requiring notice to be given in the following manner, each Loan Party
         agrees that any notice by the Agent of sale, disposition or other
         intended action hereunder or in connection herewith, whether required
         by the UCC or otherwise, shall constitute reasonable notice to the Loan
         Parties if such notice is mailed by registered or certified mail,
         return receipt requested, postage prepaid, or is delivered personally
         against receipt, at least ten (10) Business Days prior to such action
         to the Loan Parties' address specified in or pursuant to Section 15.8.
         If any Collateral is sold on terms other than payment in full at the
         time of sale, no credit shall be given against the Obligations until
         the Agent or the Lenders receive payment, and if the buyer defaults in
         payment, the Agent may resell the Collateral without further notice to
         any Loan Party. In the event the Agent seeks to take possession of all
         or any portion of the Collateral by judicial process, each Loan Party
         irrevocably waives: (A) the posting of any bond, surety or security
         with respect thereto which might otherwise be required; (B) any demand
         for possession prior to the commencement of any suit or action to
         recover the Collateral; and (C) any requirement that the Agent retain
         possession and not dispose of any Collateral until after trial or final
         judgment. Each Loan Party agrees that the Agent has no obligation to
         preserve rights to the Collateral or marshal any Collateral for the
         benefit of any Person. The Agent is hereby granted a license or other
         right to use, without charge, each Loan Party's labels, patents,
         copyrights, name, trade secrets, trade names, trademarks, and
         advertising matter, or any similar property, in completing production
         of, advertising or selling any Collateral, and each Loan Party's rights
         under all licenses and all franchise agreements shall inure to the
         Agent's benefit for such purpose. The proceeds of sale shall be applied
         first to all expenses of sale, including attorneys' fees, and then to
         the Obligations. The Agent will return any excess to the Loan Parties
         and the Loan Parties shall remain liable for any deficiency.

                  (c) If an Event of Default occurs, each Loan Party hereby
         waives all rights to notice and hearing prior to the exercise by the
         Agent of the Agent's rights to repossess the Collateral without
         judicial process or to reply, attach or levy upon the Collateral
         without notice or hearing.

                  (d) Each Loan Party recognizes that the Agent may be unable to
         effect a public sale of any or all of the Collateral or other property
         to be sold by reason of certain prohibitions contained in the laws of
         any jurisdiction outside the United States or in applicable federal or
         state securities laws but may be compelled to resort to one or more
         private sales thereof to a restricted group of purchasers who will be
         obliged to agree, among other things, to acquire such Collateral or
         other property to be sold for their own account for investment and not
         with a view to the distribution or resale thereof. Each Loan Party
         acknowledges and agrees that any such private sale may result in prices
         and other terms less favorable to the seller than if such sale were a
         public sale and, notwithstanding such circumstances, agrees that any
         such private sale shall, to the extent permitted by law, be deemed to
         have been made in a commercially reasonable manner. Unless required by
         a Requirement of Law, the Agent shall not be under any obligation to
         delay a sale of any of the Collateral or other property to be sold for
         the period of time necessary to permit the issuer of such securities to
         register such securities under the laws of any jurisdiction outside the
         United States under any applicable federal or state securities laws,
         even if such issuer would agree to do so. Each Loan Party

LOAN AND SECURITY AGREEMENT - Page 99

<PAGE>   107

         further agrees to do or cause to be done, to the extent that such Loan
         Party may do so under Requirements of Law, all such other acts and
         things as may be necessary to make such sales or resales of any portion
         or all of the Collateral or other property to be sold valid and binding
         and in compliance with any and all Requirements of Law at the Loan
         Parties' expense. Each Loan Party further agrees that a breach of any
         of the covenants contained in this Section 11.2(d) will cause
         irreparable injury to the Agent and the Lenders for which there is no
         adequate remedy at law and, as a consequence, agrees that each covenant
         contained in this Section 11.2(d) shall be specifically enforceable
         against such Loan Party and such Loan Party hereby waives and agrees,
         to the fullest extent permitted by law, not to assert as a defense
         against an action for specific performance of such covenants that (i)
         such Loan Party's failure to perform such covenants will not cause
         irreparable injury to the Agent and the Lenders or (ii) the Agent or
         the Lenders have an adequate remedy at law in respect of such breach.
         Each Loan Party further acknowledges the impossibility of ascertaining
         the amount of damages which would be suffered by the Agent and the
         Lenders by reason of a breach of any of the covenants contained in this
         Section 11.2(d) and, consequently, agrees that, if such Loan Party
         shall breach any of such covenants and the Agent or the Lenders shall
         sue for damages for such breach, such Loan Party shall pay to the
         Agent, for the benefit of the Agent and the Lenders, as liquidated
         damages and not as a penalty, an aggregate amount equal to the value of
         the Collateral or other property to be sold on the date the Agent shall
         demand compliance with this Section 11.2(d).

                                   ARTICLE 12

                              TERM AND TERMINATION

         Section 12.1 Term and Termination. The term of this Agreement shall end
on the Termination Date. The Agent upon direction from the Majority Lenders may
terminate this Agreement without notice upon the occurrence of an Event of
Default. Upon the effective date of termination of this Agreement for any reason
whatsoever, all Obligations (including all unpaid principal, accrued interest
and any early termination or prepayment fees or penalties, but excluding
indemnification obligations to the extent no claim with respect thereto has been
asserted and remains unsatisfied) shall become immediately due and payable and
the Loan Parties shall immediately arrange for the cancellation and return of
Letters of Credit then outstanding. Notwithstanding the termination of this
Agreement, until all Obligations are indefeasibly paid and performed in full in
cash, the Loan Parties shall remain bound by the terms of this Agreement and
shall not be relieved of any of their Obligations hereunder, and the Agent and
the Lenders shall retain all their rights and remedies hereunder (including the
Agent's Liens in and all rights and remedies with respect to all then existing
and after-arising Collateral).

           AMENDMENTS; WAIVER; PARTICIPATIONS; ASSIGNMENTS; SUCCESSORS

         Section 13.1 No Waivers; Cumulative Remedies. No failure by the Agent
or any Lender to exercise any right, remedy, or option under this Agreement or
any present or future supplement thereto, or in any other agreement between or
among any Loan Party and the Agent and/or any Lender, or delay by the Agent or
any Lender in exercising the same, will operate as a waiver thereof. No waiver
by the Agent or any Lender will be effective unless it is in writing, and then
only to the extent specifically stated. No waiver by the Agent or the Lenders on
any occasion shall affect or diminish the Agent's and each Lender's rights
thereafter to require strict performance by the Loan Parties of any provision of
this Agreement. The Agent's and each Lender's rights under this Agreement will
be cumulative and not exclusive of any other right or remedy which the Agent or
any Lender may have.

         Section 13.2 Amendments and Waivers. No amendment or waiver of any
provision of this Agreement or any other Loan Document, and no consent with
respect to any departure by any Loan Party therefrom, shall be effective unless
the same shall be in writing and signed by the Majority Lenders (or by the Agent
at the written request of the Majority Lenders) and the Loan Parties and then
any such waiver or consent shall be effective only in the specific instance and
for the specific purpose for which given; provided, however, that no such
waiver, amendment, or consent shall, unless in writing and signed by all the
Lenders and the Loan Parties and acknowledged by the Agent, do any of the
following:

                  (a) increase or extend the Commitment of any Lender;

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

                  (c) reduce the principal of, or the rate of interest specified
         herein on any Loan, or any fees or other amounts payable hereunder or
         under any other Loan Document;

                  (d) change the percentage of the Commitments or of the
         aggregate unpaid principal amount of the Loans which is required for
         the Lenders or any of them to take any action hereunder;

                  (e) increase any of the percentages set forth in the
         definition of the Borrowing Base;

                  (f) amend this Section or any provision of the Agreement
         providing for consent or other action by all Lenders;

                  (g) release Collateral other than as permitted by Section
         14.12;

LOAN AND SECURITY AGREEMENT - Page 101

<PAGE>   109

                  (h) change the definitions of "Majority Lenders" or "Required
         Lenders";

                  (i) increase the Maximum Revolver Amount and Unused Letter of
         Credit Subfacility; or

                  (j) change Sections 9.23, 9.25 or 9.26, clause (i) of the
         definition of "Restricted Investments" or the definitions of "Adjusted
         Tangible Assets," "Capital Expenditures," "Capex Reimbursements,"
         "Fixed Charge Coverage Ratio," "Adjusted Tangible Net Worth," "Adjusted
         Tangible Net Worth Requirement," "Adjusted Tangible Net Worth
         Requirement Increase," "Net Transfers" or "Net Transfers Allowed."

provided, however, the Agent may, in its sole discretion and notwithstanding the
limitations contained in clause (e) and clause (i) above and any other terms of
this Agreement, make Revolving Loans (including Agent Advances) in an amount not
to exceed ten percent (10.0%) of the Borrowing Base and, provided further, that
no amendment, waiver or consent shall, unless in writing and signed by the
Agent, affect the rights or duties of the Agent under this Agreement or any
other Loan Document.

         Section 13.3 Assignments; Participations.

                  (a) Any Lender may, with the written consent of the Agent
         (which consent shall not be unreasonably withheld by the Agent) and, if
         no Default or Event of Default has occurred and is continuing at the
         time any assignment is effected in accordance with this Section, Parent
         (such approval in each such case not to be unreasonably withheld or
         delayed, and in the case of any such approval requested of Parent such
         approval shall be deemed given by Parent if no objection from Parent is
         received by the assigning Lender and the Agent within four (4) Business
         Days after notice of such proposed assignment has been provided to
         Parent by the Agent or the assigning Lender), assign and delegate to
         one or more Eligible Assignees (provided that no written consent of the
         Agent shall be required in connection with any assignment and
         delegation by a Lender to an Affiliate of such Lender) (each an
         "Assignee") all, or any ratable part of all, of the Loans, the
         Commitments and the other rights and obligations of such Lender
         hereunder, in a minimum amount of $5,000,000 (provided that, unless an
         assignor Lender has assigned and delegated all of its Loans and
         Commitments, no such assignment and/or delegation shall be permitted
         unless, after giving effect thereto, such assignor Lender retains a
         Commitment in a minimum amount of $5,000,000); provided, however, that
         the Loan Parties and the Agent may continue to deal solely and directly
         with such Lender in connection with the interest so assigned to an
         Assignee until (i) written notice of such assignment, together with
         payment instructions, addresses and related information with respect to
         the Assignee, shall have been given to the Loan Parties and the Agent
         by such Lender and the Assignee; (ii) such Lender and its Assignee
         shall have delivered to the Loan Parties and the Agent an Assignment
         and Acceptance in the form of Exhibit F ("Assignment and Acceptance")
         together with any Note or Notes subject to such assignment and (iii)
         the assignor Lender or Assignee has paid to the Agent a processing fee
         in the amount of $3,000.

                  (b) From and after the date that the Agent notifies the
         assignor Lender that it has received an executed Assignment and
         Acceptance and payment of the above-referenced

LOAN AND SECURITY AGREEMENT - Page 102

<PAGE>   110

         processing fee, (i) the Assignee thereunder shall be a party hereto
         and, to the extent that rights and obligations, including, but not
         limited to, the obligation to participate in Letters of Credit and
         Credit Support have been assigned to it pursuant to such Assignment and
         Acceptance, shall have the rights and obligations of a Lender under the
         Loan Documents, and (ii) the assignor Lender shall, to the extent that
         rights and obligations hereunder and under the other Loan Documents
         have been assigned by it pursuant to such Assignment and Acceptance,
         relinquish its rights and be released from its obligations under this
         Agreement (and in the case of an Assignment and Acceptance covering all
         or the remaining portion of an assigning Lender's rights and
         obligations under this Agreement, such Lender shall cease to be a party
         hereto).

                  (c) By executing and delivering an Assignment and Acceptance,
         the assigning Lender thereunder and the Assignee thereunder confirm to
         and agree with each other and the other parties hereto as follows: (i)
         other than as provided in such Assignment and Acceptance, such
         assigning Lender makes no representation or warranty and assumes no
         responsibility with respect to any statements, warranties or
         representations made in or in connection with this Agreement or the
         execution, legality, validity, enforceability, genuineness, sufficiency
         or value of this Agreement or any other Loan Document furnished
         pursuant hereto or the attachment, perfection, or priority of any Lien
         granted by the Loan Parties to the Agent or any Lender in the
         Collateral; (ii) such assigning Lender makes no representation or
         warranty and assumes no responsibility with respect to the financial
         condition of the Loan Parties or the performance or observance by any
         Loan Party of any of its obligations under this Agreement or any other
         Loan Document furnished pursuant hereto; (iii) such Assignee confirms
         that it has received a copy of this Agreement, together with such other
         documents and information as it has deemed appropriate to make its own
         credit analysis and decision to enter into such Assignment and
         Acceptance; (iv) such Assignee will, independently and without reliance
         upon the Agent, such assigning Lender or any other Lender, and based on
         such documents and information as it shall deem appropriate at the
         time, continue to make its own credit decisions in taking or not taking
         action under this Agreement; (v) such Assignee appoints and authorizes
         the Agent to take such action as agent on its behalf and to exercise
         such powers under this Agreement as are delegated to the Agent by the
         terms hereof, together with such powers, including the discretionary
         rights and incidental power, as are reasonably incidental thereto; and
         (vi) such Assignee agrees that it will perform in accordance with their
         terms all of the obligations which by the terms of this Agreement are
         required to be performed by it as a Lender.

                  (d) Immediately upon each Assignee's making its processing fee
         payment under the Assignment and Acceptance, this Agreement shall be
         deemed to be amended to the extent, but only to the extent, necessary
         to reflect the addition of the Assignee and the resulting adjustment of
         the Commitments arising therefrom. The Commitment allocated to each
         Assignee shall reduce such Commitments of the assigning Lender pro
         tanto.

                  (e) Any Lender may at any time sell to one or more commercial
         banks, financial institutions, or other Persons not Affiliates of the
         Loan Parties (a "Participant") participating interests in any Loans,
         the Commitment of that Lender and the other interests of that Lender

LOAN AND SECURITY AGREEMENT - Page 103

<PAGE>   111

         (the "Originating Lender") hereunder and under the other Loan
         Documents; provided, however, that (i) the originating Lender's
         obligations under this Agreement shall remain unchanged, (ii) the
         originating Lender shall remain solely responsible for the performance
         of such obligations, (iii) the Loan Parties and the Agent shall
         continue to deal solely and directly with the originating Lender in
         connection with the originating Lender's rights and obligations under
         this Agreement and the other Loan Documents, and (iv) no Lender shall
         transfer or grant any participating interest under which the
         Participant has rights to approve any amendment to, or any consent or
         waiver with respect to, this Agreement or any other Loan Document, and
         all amounts payable by the Loan Parties hereunder shall be determined
         as if such Lender had not sold such participation; except that, if
         amounts outstanding under this Agreement are due and unpaid, or shall
         have been declared or shall have become due and payable upon the
         occurrence of an Event of Default, each Participant shall be deemed to
         have the right of setoff in respect of its participating interest in
         amounts owing under this Agreement to the same extent and subject to
         the same limitation as if the amount of its participating interest were
         owing directly to it as a Lender under this Agreement.

                  (f) Notwithstanding any other provision in this Agreement, any
         Lender may at any time create a security interest in, or pledge, all or
         any portion of its rights under and interest in this Agreement in favor
         of any Federal Reserve Bank in accordance with Regulation A of the FRB
         or U.S. Treasury Regulation 31 CFR Section 203.14, or otherwise, and
         such Federal Reserve Bank may enforce such pledge or security interest
         in any manner permitted under applicable law, provided, that no such
         action shall release or otherwise relieve any Lender of its obligations
         under this Agreement.

                                   ARTICLE 14

                                    THE AGENT

         Section 14.1 Appointment and Authorization. Each Lender hereby
designates and appoints the Agent as its agent under this Agreement and the
other Loan Documents and each Lender hereby irrevocably authorizes the Agent to
take such action on its behalf under the provisions of this Agreement and each
other Loan Document and to exercise such powers and perform such duties as are
expressly delegated to it by the terms of this Agreement or any other Loan
Document, together with such powers as are reasonably incidental thereto. The
Agent agrees to act as such on the express conditions contained in this Article
14. The provisions of this Article 14 are solely for the benefit of the Agent
and the Lenders and the Loan Parties shall have no rights as a third party
beneficiary of any of the provisions contained herein. Notwithstanding any
provision to the contrary contained elsewhere in this Agreement or in any other
Loan Document, the Agent shall not have any duties or responsibilities, except
those expressly set forth herein, nor shall the Agent have or be deemed to have
any fiduciary relationship with any Lender, and no implied covenants, functions,
responsibilities, duties, obligations or liabilities shall be read into this
Agreement or any other Loan Document or otherwise exist against the Agent.
Without limiting the generality of the foregoing sentence, the use of the term
"agent" in this Agreement with reference to the Agent is not intended to connote
any fiduciary or other implied (or express) obligations arising under agency
doctrine of any applicable law. Instead, such term is used merely as a matter of
market custom, and is intended

LOAN AND SECURITY AGREEMENT - Page 104

<PAGE>   112

to create or reflect only an administrative relationship between independent
contracting parties. Except as expressly otherwise provided in this Agreement,
the Agent shall have and may use its sole discretion with respect to exercising
or refraining from exercising any discretionary rights or taking or refraining
from taking any actions which the Agent is expressly entitled to take or assert
under this Agreement and the other Loan Documents, including (a) the
determination of the applicability of ineligibility criteria and the
determination of Approved Foreign Accounts, in each case with respect to the
calculation of the Borrowing Base, (b) the making of Agent Advances pursuant to
Section 2.2(i), and (c) the exercise of remedies pursuant to Section 11.2, and
any action so taken or not taken shall be deemed consented to by the Lenders.

         Section 14.2 Delegation of Duties. The Agent may execute any of its
duties under this Agreement or any other Loan Document by or through agents,
employees or attorneys-in-fact and shall be entitled to advice of counsel
concerning all matters pertaining to such duties. The Agent shall not be
responsible for the negligence or misconduct of any agent or attorney-in-fact
that it selects as long as such selection was made without gross negligence or
willful misconduct.

         Section 14.3 Liability of the Agent. None of the Agent-Related Persons
shall (i) 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), or (ii) be responsible in any manner to any of the Lenders for any
recital, statement, representation or warranty made by the Loan Parties or any
Subsidiary or Affiliate of the Loan Parties, or any officer thereof, contained
in this Agreement or in any other Loan Document, or in any certificate, report,
statement or other document referred to or provided for in, or received by the
Agent under or in connection with, this Agreement or any other Loan Document, or
the validity, effectiveness, genuineness, enforceability or sufficiency of this
Agreement or any other Loan Document, or for any failure of any Loan Parties 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
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 Parties or
any of the Loan Party's Subsidiaries or Affiliates.

         Section 14.4 Reliance by the Agent.

                  (a) The Agent shall be entitled to rely, and shall be fully
         protected in relying, upon any writing, resolution, 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 Agent. The Agent shall be fully
         justified in failing or refusing to take any action under this
         Agreement or any other Loan Document unless it shall first receive such
         advice or concurrence of the Majority Lenders as it deems appropriate
         and, if it so requests, it shall first be indemnified to its
         satisfaction by the Lenders against any and all liability and expense
         which may be incurred by it by reason of taking or continuing to take
         any such action. The Agent shall in all cases be fully protected

LOAN AND SECURITY AGREEMENT - Page 105

<PAGE>   113

         in acting, or in refraining from acting, under this Agreement or any
         other Loan Document in accordance with a request or consent of the
         Majority Lenders (or all Lenders if so required by Section 13.2) and
         such request and any action taken or failure to act pursuant thereto
         shall be binding upon all of the Lenders.

                  (b) For purposes of determining compliance with the conditions
         specified in Section 10.1, each Lender that has executed this Agreement
         shall be deemed to have consented to, approved or accepted or to be
         satisfied with, each document or other matter either sent by the Agent
         to such Lender for consent, approval, acceptance or satisfaction, or
         required thereunder to be consented to or approved by or acceptable or
         satisfactory to the Lender.

         Section 14.5 Notice of Default. The Agent shall not be deemed to have
knowledge or notice of the occurrence of any Default or Event of Default, unless
the Agent shall have received written notice from a Lender or any Loan Party
referring to this Agreement, describing such Default or Event of Default and
stating that such notice is a "notice of default." The Agent will notify the
Lenders of its receipt of any such notice. The Agent shall take such action with
respect to such Default or Event of Default as may be requested by the Majority
Lenders in accordance with Section 11; provided, however, that unless and until
the Agent has received any such request, the Agent may (but shall not be
obligated to) take such action, or refrain from taking such action, with respect
to such Default or Event of Default as it shall deem advisable.

         Section 14.6 Credit Decision. Each Lender acknowledges that none of the
Agent-Related Persons has made any representation or warranty to it, and that no
act by the Agent hereinafter taken, including any review of the affairs of the
Loan Parties and their Affiliates, shall be deemed to constitute any
representation or warranty by any Agent-Related Person to any Lender. Each
Lender represents to the 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 Affiliates, and all applicable
bank regulatory laws relating to the transactions contemplated hereby, and made
its own decision to enter into this Agreement and to extend credit to the Loan
Parties. 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 Loan
Parties. Except for notices, reports and other documents expressly herein
required to be furnished to the Lenders by the Agent, the Agent shall not have
any duty or responsibility to provide any Lender with any credit or other
information concerning the business, prospects, operations, property, financial
and other condition or creditworthiness of any Loan Parties which may come into
the possession of any of the Agent-Related Persons.

         Section 14.7 Indemnification. Whether or not the transactions
contemplated hereby are consummated, the Lenders shall indemnify upon demand the
Agent-Related Persons (to the extent

LOAN AND SECURITY AGREEMENT - Page 106

<PAGE>   114

not reimbursed by or on behalf of the Loan Parties and without limiting the
obligation of the Loan Parties to do so), pro rata, from and against any and all
Indemnified Liabilities as such term is defined in Section 15.11; provided,
however, that no Lender shall be liable for the payment to the Agent-Related
Persons of any portion of such Indemnified Liabilities resulting solely from
such Person's gross negligence or willful misconduct. Without limitation of the
foregoing, each Lender shall reimburse the Agent upon demand for its ratable
share of any costs or out-of-pocket expenses (including Attorney Costs) incurred
by the Agent in connection with the preparation, execution, delivery,
administration, modification, amendment or enforcement (whether through
negotiations, legal proceedings or otherwise) of, or legal advice in respect of
rights or responsibilities under, this Agreement, any other Loan Document, or
any document contemplated by or referred to herein, to the extent that the Agent
is not reimbursed for such expenses by or on behalf of the Loan Parties. The
undertaking in this Section shall survive the payment of all Obligations
hereunder and the resignation or replacement of the Agent.

         Section 14.8 The Agent in Individual Capacity. The Bank and its
Affiliates may make loans to, issue letters of credit for the account of, accept
deposits from, acquire equity interests in and generally engage in any kind of
banking, trust, financial advisory, underwriting or other business with any Loan
Party and its Subsidiaries and Affiliates as though the Bank were not the Agent
hereunder and without notice to or consent of the Lenders. The Lenders
acknowledge that, pursuant to such activities, the Bank or its Affiliates may
receive information regarding any Loan Party or its Subsidiaries (including
information that may be subject to confidentiality obligations in favor of any
such Loan Party or Subsidiary) and acknowledge that the Agent shall be under no
obligation to provide such information to them. With respect to its Loans, the
Bank shall have the same rights and powers under this Agreement as any other
Lender and may exercise the same as though it were not the Agent, and the terms
"Lender" and "Lenders" include the Bank in its individual capacity.

         Section 14.9 Successor Agent. The Agent may resign as the Agent upon 30
days' notice to the Lenders and the Loan Parties, such resignation to be
effective upon the acceptance of a successor agent to its appointment as the
Agent. In the event the Bank sells all of its Commitment and Revolving Loans as
part of a sale, transfer or other disposition by the Bank of substantially all
of its loan portfolio, the Bank shall resign as the Agent and such purchaser or
transferee shall become the successor Agent hereunder. If the Agent resigns
under this Agreement, subject to the proviso in the preceding sentence, the
Majority Lenders shall appoint from among the Lenders a successor agent for the
Lenders. If no successor agent is appointed prior to the effective date of the
resignation of the Agent, the Agent may appoint, after consulting with the
Lenders and the Loan Parties, a successor agent from among the Lenders. Upon the
acceptance of its appointment as successor agent hereunder, such successor agent
shall succeed to all the rights, powers and duties of the retiring Agent and the
term "Agent" shall mean such successor agent and the retiring Agent's
appointment, powers and duties as the Agent shall be terminated. After any
retiring Agent's resignation hereunder as the Agent, the provisions of this
Article 14 shall inure to its benefit as to any actions taken or omitted to be
taken by it while it was the Agent under this Agreement. If no Default or Event
of Default has occurred and is continuing at the time the appointment of any
successor Agent is effected in accordance with this Section, then such
appointment shall be subject to the approval of the Parent (such approval not to
be unreasonably withheld or delayed, and such approval shall be deemed given by
Parent if no objection from Parent is received by the resigning Agent and the
Lenders within ten

LOAN AND SECURITY AGREEMENT - Page 107

<PAGE>   115

(10) Business Days after notice of such proposed assignment has been provided to
Parent by the resigning Agent or any Lender). If a Default or Event of Default
has occurred and is continuing at the time the appointment of any successor
Agent is effected in accordance with this Section, then no such approval by
Parent or any other Loan Party shall be required.

         Section 14.10 Withholding Tax.

                  (a) If any Lender is a "foreign corporation, partnership or
         trust" within the meaning of the Code and such Lender claims exemption
         from, or a reduction of, U.S. withholding tax under Sections 1441 or
         1442 of the Code, such Lender agrees with and in favor of the Agent, to
         deliver to the Agent:

                           (i) if such Lender claims an exemption from, or a
                  reduction of, withholding tax under a United States tax
                  treaty, properly completed IRS Forms 1001 and W8 before the
                  payment of any interest in the first calendar year and before
                  the payment of any interest in each third succeeding calendar
                  year during which interest may be paid under this Agreement;

                           (ii) if such Lender claims that interest paid under
                  this Agreement is exempt from United States withholding tax
                  because it is effectively connected with a United States trade
                  or business of such Lender, two properly completed and
                  executed copies of IRS Form 4224 before the payment of any
                  interest is due in the first taxable year of such Lender and
                  in each succeeding taxable year of such Lender during which
                  interest may be paid under this Agreement, and IRS Form W9;
                  and

                           (iii) such other form or forms as may be required
                  under the Code or other laws of the United States as a
                  condition to exemption from, or reduction of, United States
                  withholding tax.

         Such Lender agrees to promptly notify the Agent of any change in
         circumstances which would modify or render invalid any claimed
         exemption or reduction.

                  (b) If any Lender claims exemption from, or reduction of,
         withholding tax under a United States tax treaty by providing IRS Form
         1001 and such Lender sells, assigns, grants a participation in, or
         otherwise transfers all or part of the Obligations owing to such
         Lender, such Lender agrees to notify the Agent of the percentage amount
         in which it is no longer the beneficial owner of Obligations to such
         Lender. To the extent of such percentage amount, the Agent will treat
         such Lender's IRS Form 1001 as no longer valid.

                  (c) If any Lender claiming exemption from United States
         withholding tax by filing IRS Form 4224 with the Agent sells, assigns,
         grants a participation in, or otherwise transfers all or part of the
         Obligations owing to such Lender, such Lender agrees to undertake sole
         responsibility for complying with the withholding tax requirements
         imposed by Sections 1441 and 1442 of the Code.

<PAGE>   116

                  (d) If any Lender is entitled to a reduction in the applicable
         withholding tax, the Agent may withhold from any interest payment to
         such Lender an amount equivalent to the applicable withholding tax
         after taking into account such reduction. If the forms or other
         documentation required by subsection (a) of this Section are not
         delivered to the Agent, then the Agent may withhold from any interest
         payment to such Lender not providing such forms or other documentation
         an amount equivalent to the applicable withholding tax.

                  (e) If the IRS or any other Governmental Authority of the
         United States or other jurisdiction asserts a claim that the Agent did
         not properly withhold tax from amounts paid to or for the account of
         any Lender (because the appropriate form was not delivered, was not
         properly executed, or because such Lender failed to notify the Agent of
         a change in circumstances which rendered the exemption from, or
         reduction of, withholding tax ineffective, or for any other reason)
         such Lender shall indemnify the Agent fully for all amounts paid,
         directly or indirectly, by the Agent as tax or otherwise, including
         penalties and interest, and including any taxes imposed by any
         jurisdiction on the amounts payable to the Agent under this Section,
         together with all costs and expenses (including Attorney Costs). The
         obligation of the Lenders under this subsection shall survive the
         payment of all Obligations and the resignation or replacement of the
         Agent.

         Section 14.11 Reserved.

         Section 14.12 Collateral Matters.

                  (a) The Lenders hereby irrevocably authorize the Agent, at its
         option and in its sole discretion, to release any Agent's Lien upon any
         Collateral (i) upon the termination of the Commitments and payment and
         satisfaction in full of all Loans and reimbursement obligations in
         respect of Letters of Credit and Credit Support, and the termination of
         all outstanding Letters of Credit (whether or not any of such
         obligations are due) and all other Obligations (other that
         indemnification obligations to the extent no claim with respect thereto
         has been threatened or asserted and remains unsatisfied); (ii)
         constituting property being sold or disposed of if the Loan Party
         disposing of such property certifies to the Agent that the sale or
         disposition is made in compliance with Section 9.9 (and the Agent may
         rely conclusively on any such certificate, without further inquiry);
         (iii) constituting property in which no Loan Party owned any interest
         at the time the Lien was granted or at any time thereafter; or (iv)
         constituting property leased to a Loan Party under a lease which has
         expired or been terminated in a transaction permitted under this
         Agreement. Except as provided above, the Agent will not release any of
         the Agent's Liens without the prior written authorization of the
         Lenders; provided that the Agent may, in its discretion, release the
         Agent's Liens on Collateral valued in the aggregate not in excess of
         $7,500,000 during any one year period without the prior written
         authorization of the Lenders. Upon request by the Agent or the Loan
         Parties at any time, the Lenders will confirm in writing the Agent's
         authority to release any Agent's Liens upon particular types or items
         of Collateral pursuant to this Section 14.12.

                  (b) Upon receipt by the Agent of any authorization required
         pursuant to Section 14.12(a) from the Lenders of the Agent's authority
         to release any Agent's Liens upon

LOAN AND SECURITY AGREEMENT - Page 109

<PAGE>   117

         particular types or items of Collateral, and upon at least five (5)
         Business Days' prior written request by the Loan Parties, the Agent
         shall (and is hereby irrevocably authorized by the Lenders to) execute
         such documents as may be necessary to evidence the release of the
         Agent's Liens upon such Collateral; provided, however, that (i) the
         Agent shall not be required to execute any such document on terms
         which, in the Agent's opinion, would expose the Agent to liability or
         create any obligation or entail any consequence other than the release
         of such Liens without recourse or warranty, and (ii) such release shall
         not in any manner discharge, affect or impair the Obligations or any
         Liens (other than those expressly being released) upon (or obligations
         of the Loan Parties in respect of) all interests retained by the Loan
         Parties, including the proceeds of any sale, all of which shall
         continue to constitute part of the Collateral.

                  (c) The Agent shall have no obligation whatsoever to any of
         the Lenders to assure that the Collateral exists or is owned by any
         Loan Party or is cared for, protected or insured or has been
         encumbered, or that the Agent's Liens have been properly or
         sufficiently or lawfully created, perfected, protected or enforced or
         are entitled to any particular priority, or to exercise at all or in
         any particular manner or under any duty of care, disclosure or
         fidelity, or to continue exercising, any of the rights, authorities and
         powers granted or available to the Agent pursuant to any of the Loan
         Documents, it being understood and agreed that in respect of the
         Collateral, or any act, omission or event related thereto, the Agent
         may act in any manner it may deem appropriate, in its sole discretion
         given the Agent's own interest in the Collateral in its capacity as one
         of the Lenders and that the Agent shall have no other duty or liability
         whatsoever to any Lender as to any of the foregoing.

         Section 14.13 Restrictions on Actions by Lenders; Sharing of Payments.

                  (a) Each of the Lenders agrees that it shall not, without the
         express consent of all Lenders, and that it shall, to the extent it is
         lawfully entitled to do so, upon the request of all Lenders, set off
         against the Obligations, any amounts owing by such Lender to any Loan
         Party or any accounts of any Loan Party now or hereafter maintained
         with such Lender. Each of the Lenders further agrees that it shall not,
         unless specifically requested to do so by the Agent, take or cause to
         be taken any action to enforce its rights under this Agreement or
         against any Loan Party, including the commencement of any legal or
         equitable proceedings, to foreclose any Lien on, or otherwise enforce
         any security interest in, any of the Collateral.

                  (b) If at any time or times any Lender shall receive (i) by
         payment, foreclosure, setoff or otherwise, any proceeds of Collateral
         or any payments with respect to the Obligations owing to such Lender
         arising under, or relating to, this Agreement or the other Loan
         Documents, except for any such proceeds or payments received by such
         Lender from the Agent pursuant to the terms of this Agreement, or (ii)
         payments from the Agent in excess of such Lender's ratable portion of
         all such distributions by the Agent, such Lender shall promptly (1)
         turn the same over to the Agent, in kind, and with such endorsements as
         may be required to negotiate the same to the Agent, or in same day
         funds, as applicable, for the account of all of the Lenders and for
         application to the Obligations in accordance with the applicable
         provisions of this Agreement, or (2) purchase, without recourse or
         warranty, an

LOAN AND SECURITY AGREEMENT - Page 110

         undivided interest and participation in the Obligations owed to the
         other Lenders so that such excess payment received shall be applied
         ratably as among the Lenders in accordance with their Pro Rata Shares;
         provided, however, that if all or part of such excess payment received
         by the purchasing party is thereafter recovered from it, those
         purchases of participations shall be rescinded in whole or in part, as
         applicable, and the applicable portion of the purchase price paid
         therefor shall be returned to such purchasing party, but without
         interest except to the extent that such purchasing party is required to
         pay interest in connection with the recovery of the excess payment.

         Section 14.14 Agency for Perfection. Each Lender hereby appoints each
other Lender as agent for the purpose of perfecting the Lenders' security
interest in assets which, in accordance with Article 9 of the UCC can be
perfected only by possession. Should any Lender (other than the Agent) obtain
possession of any such Collateral, such Lender shall notify the Agent thereof,
and, promptly upon the Agent's request therefor shall deliver such Collateral to
the Agent or in accordance with the Agent's instructions.

         Section 14.15 Payments by the Agent to Lenders. All payments to be made
by the Agent to the Lenders shall be made by bank wire transfer or internal
transfer of immediately available funds to each Lender pursuant to wire transfer
instructions delivered in writing to the Agent on or prior to the Closing Date
(or if such Lender is an Assignee, on the applicable Assignment and Acceptance),
or pursuant to such other wire transfer instructions as each party may designate
for itself by written notice to the Agent. Concurrently with each such payment,
the Agent shall identify whether such payment (or any portion thereof)
represents principal, premium or interest on the Loans, or otherwise.

         Section 14.16 Concerning the Collateral and the Related Loan Documents.
Each Lender authorizes and directs the Agent to enter into this Agreement and
the other Loan Documents relating to the Collateral, for the ratable benefit of
the Agent and the Lenders. Each Lender agrees that any action taken by the
Agent, Majority Lenders or Required Lenders, as applicable, in accordance with
the terms of this Agreement or the other Loan Documents relating to the
Collateral, and the exercise by the Agent, the Majority Lenders, or the Required
Lenders, as applicable, of their respective powers set forth therein or herein,
together with such other powers that are reasonably incidental thereto, shall be
binding upon all of the Lenders.

         Section 14.17 Field Audit and Examination Reports; Disclaimer by
Lenders. By signing this Agreement, each Lender:

                  (a) is deemed to have requested that the Agent furnish such
         Lender, promptly after it becomes available, a copy of each field audit
         or examination report (each a "Report" and collectively, "Reports")
         prepared by the Agent;

                  (b) expressly agrees and acknowledges that neither the Bank
         nor the Agent (i) makes any representation or warranty as to the
         accuracy of any Report, or (ii) shall be liable for any information
         contained in any Report;

LOAN AND SECURITY AGREEMENT - Page 111

<PAGE>   119

                  (c) expressly agrees and acknowledges that the Reports are not
         comprehensive audits or examinations, that the Agent or other party
         performing any audit or examination will inspect only specific
         information regarding the Loan Parties and will rely significantly upon
         Loan Parties' books and records, as well as on representations of the
         Loan Parties' personnel;

                  (d) agrees to keep all Reports confidential and strictly for
         its internal use, and not to distribute except to its participants, or
         use any Report in any other manner; and

                  (e) without limiting the generality of any other
         indemnification provision contained in this Agreement, agrees: (i) to
         hold the Agent-Related Persons and any such other Lender preparing a
         Report harmless from any action the indemnifying Lender may take or
         conclusion the indemnifying Lender may reach or draw from any Report in
         connection with any loans or other credit accommodations that the
         indemnifying Lender has made or may make to the Borrowers, or the
         indemnifying Lender's participation in, or the indemnifying Lender's
         purchase of, a loan or loans of the Borrowers; and (ii) to pay and
         protect, and indemnify, defend and hold the Agent-Related Persons and
         any such other Lender preparing a Report harmless from and against, the
         claims, actions, proceedings, damages, costs, expenses and other
         amounts (including Attorney Costs) incurred by any Agent-Related Person
         and any such other Lender preparing a Report as the direct or indirect
         result of any third parties who might obtain all or part of any Report
         through the indemnifying Lender; provided, however, that no Lender
         shall be liable for the payment to any such Agent-Related Person or any
         such other Lender of any portion of such Indemnified Liabilities
         resulting solely from any such Agent-Related Person's or any such
         other Lender's gross negligence or willful misconduct.

         Section 14.18 Relation Among Lenders. The Lenders are not partners or
co-venturers, and no Lender shall be liable for the acts or omissions of, or
(except as otherwise set forth herein in case of the Agent) authorized to act
for, any other Lender.

         Section 15.1 Cumulative Remedies; No Prior Recourse to Collateral. The
enumeration herein of the Agent's and each Lender's rights and remedies is not
intended to be exclusive, and such rights and remedies are in addition to and
not by way of limitation of any other rights or remedies that the Agent and the
Lenders may have under the UCC or other applicable law. The Agent and the
Lenders shall have the right, in their sole discretion, to determine which

right or remedy shall not preclude the exercise of any others, all of which
shall be cumulative. The Agent and the Lenders may, without limitation, proceed
directly against any Person liable therefor to collect the Obligations without
any prior recourse to the Collateral. No failure to exercise and no delay in
exercising, on the part of the Agent or any Lender, 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.

Failure or delay in delivering copies of any notice, demand, request, consent,
approval, declaration or other communication to the persons designated above to
receive copies shall not adversely affect the effectiveness of such notice,
demand, request, consent, approval, declaration or other communication.

         Section 15.9 Waiver of Notices. Unless otherwise expressly provided
herein, each Loan Party waives presentment, protest and notice of demand or
dishonor and protest as to any instrument, notice of intent to accelerate the
Obligations and notice of acceleration of the Obligations, as well as any and
all other notices to which it might otherwise be entitled. No notice to or
demand on any Loan Party which the Agent or any Lender may elect to give shall
entitle any Loan Party to any or further notice or demand in the same, similar
or other circumstances.

         Section 15.10 Binding Effect. The provisions of this Agreement shall be
binding upon and inure to the benefit of the respective representatives,
successors, and assigns of the parties hereto; provided, however, that no
interest herein may be assigned by any Loan Party without prior written consent
of the Agent and each Lender. The rights and benefits of the Agent and the
Lenders hereunder shall, if such Persons so agree, inure to any party acquiring
any interest in the Obligations or any part thereof.

         Section 15.11 Indemnity of the Agent and the Lenders by the Loan
Parties.

                  (a) EACH LOAN PARTY AGREES TO DEFEND, INDEMNIFY AND HOLD THE

         WAY RELATING TO OR ARISING OUT OF THIS AGREEMENT OR ANY DOCUMENT
         CONTEMPLATED BY OR REFERRED TO HEREIN, OR THE TRANSACTIONS CONTEMPLATED
         HEREBY, OR ANY ACTION TAKEN OR OMITTED BY ANY SUCH PERSON UNDER OR IN
         CONNECTION WITH ANY OF THE FOREGOING, INCLUDING WITH RESPECT TO ANY
         INVESTIGATION, LITIGATION OR PROCEEDING (INCLUDING ANY INSOLVENCY
         PROCEEDING OR APPELLATE PROCEEDING) RELATED TO OR ARISING OUT OF THIS
         AGREEMENT, ANY OTHER LOAN DOCUMENT, OR THE LOANS OR THE USE OF THE
         PROCEEDS THEREOF, WHETHER OR NOT ANY INDEMNIFIED PERSON IS A PARTY
         THERETO (ALL THE FOREGOING, COLLECTIVELY, THE "INDEMNIFIED
         LIABILITIES"); PROVIDED, THAT THE LOAN PARTIES SHALL HAVE NO OBLIGATION
         HEREUNDER TO ANY INDEMNIFIED PERSON WITH RESPECT TO INDEMNIFIED
         LIABILITIES RESULTING SOLELY FROM THE WILLFUL MISCONDUCT OR GROSS
         NEGLIGENCE OF SUCH INDEMNIFIED PERSON. THE AGREEMENTS IN THIS SECTION
         SHALL SURVIVE PAYMENT OF ALL OTHER OBLIGATIONS.

                  (b) EACH LOAN PARTY AGREES TO INDEMNIFY, DEFEND AND HOLD
         HARMLESS THE AGENT AND THE LENDERS FROM ANY LOSS OR LIABILITY DIRECTLY
         OR INDIRECTLY ARISING OUT OF THE USE, GENERATION, MANUFACTURE,
         PRODUCTION, STORAGE, RELEASE, THREATENED RELEASE, DISCHARGE, DISPOSAL
         OR PRESENCE OF A HAZARDOUS SUBSTANCE RELATING TO ANY LOAN PARTY'S
         OPERATIONS, BUSINESS OR PROPERTY. THIS INDEMNITY WILL APPLY WHETHER THE
         HAZARDOUS SUBSTANCE IS ON, UNDER OR ABOUT ANY LOAN PARTY'S PROPERTY OR
         OPERATIONS OR PROPERTY LEASED TO ANY LOAN PARTY. THE INDEMNITY INCLUDES
         BUT IS NOT LIMITED TO ATTORNEYS' FEES (INCLUDING THE REASONABLE
         ESTIMATE OF THE ALLOCATED COST OF IN-HOUSE COUNSEL AND STAFF). THE
         INDEMNITY EXTENDS TO THE AGENT AND THE LENDERS, THEIR PARENTS,
         AFFILIATES, SUBSIDIARIES AND ALL OF THEIR DIRECTORS, OFFICERS,
         EMPLOYEES, AGENTS, SUCCESSORS, ATTORNEYS AND ASSIGNS. "HAZARDOUS
         SUBSTANCES" MEANS ANY SUBSTANCE, MATERIAL OR WASTE THAT IS OR BECOMES
         DESIGNATED OR REGULATED AS "TOXIC," "HAZARDOUS," "POLLUTANT," OR
         "CONTAMINANT" OR A SIMILAR DESIGNATION OR REGULATION UNDER ANY FEDERAL,
         STATE OR LOCAL LAW (WHETHER UNDER COMMON LAW, STATUTE, REGULATION OR
         OTHERWISE) OR JUDICIAL OR ADMINISTRATIVE INTERPRETATION OF SUCH,
         INCLUDING PETROLEUM OR NATURAL GAS. THIS INDEMNITY WILL SURVIVE
         REPAYMENT OF ALL OTHER OBLIGATIONS.

         Section 15.12 Limitation of Liability. No claim may be made by any Loan
Party, any Lender or other Person against the Agent, any Lender, or the
affiliates, directors, officers, officers, employees, or agents of any of them
for any special, indirect, consequential or punitive damages in

LOAN AND SECURITY AGREEMENT - Page 117

<PAGE>   125

respect of any claim for breach of contract or any other theory of liability
arising out of or related to the transactions contemplated by this Agreement or
any other Loan Document, or any act, omission or event occurring in connection
therewith, and each Loan Party and each Lender hereby waives, releases and
agrees not to sue upon any claim for such damages, whether or not accrued and
whether or not known or suspected to exist in its favor.

         Section 15.13 Final Agreement. This Agreement and the other Loan
Documents are intended by the Loan Parties, the Agent and the Lenders to be the
final, complete, and exclusive expression of the agreement between them. This
Agreement supersedes any and all prior oral or written agreements relating to
the subject matter hereof. No modification, rescission, waiver, release, or
amendment of any provision of this Agreement or any other Loan Document shall be
made, except by a written agreement signed by the Loan Parties and a duly
authorized officer of each of the Agent and the requisite Lenders.

         Section 15.14 Counterparts. This Agreement may be executed in any
number of counterparts, and by the Agent, each Lender and the Loan Parties in
separate counterparts, each of which shall be an original, but all of which
shall together constitute one and the same agreement; signature pages may be
detached from multiple separate counterparts and attached to a single
counterpart so that all signature pages are physically attached to the same
document.

         Section 15.15 Captions. The captions contained in this Agreement are
for convenience of reference only, are without substantive meaning and should
not be construed to modify, enlarge, or restrict any provision.

         Section 15.16 Right of Setoff. In addition to any rights and remedies
of the Lenders provided by law, if an Event of Default exists or the Loans have
been accelerated, each Lender is authorized at any time and from time to time,
without prior notice to the Loan Parties, any such notice being waived by the
Loan Parties 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 any Loan Party against any and all Obligations
owing to such Lender by such Loan Party, now or hereafter existing, irrespective
of whether or not the Agent or such Lender shall have made demand under this
Agreement or any Loan Document and although such Obligations may be contingent
or unmatured. Each Lender agrees promptly to notify the Loan Parties and the
Agent after any such setoff and application made by such Lender; provided,
however, that the failure to give such notice shall not affect the validity of
such setoff and application. NOTWITHSTANDING THE FOREGOING, NO LENDER SHALL
EXERCISE ANY RIGHT OF SET-OFF, BANKER'S LIEN, OR THE LIKE AGAINST ANY DEPOSIT
ACCOUNT OR PROPERTY OF ANY LOAN PARTY HELD OR MAINTAINED BY SUCH LENDER WITHOUT
THE PRIOR WRITTEN UNANIMOUS CONSENT OF THE LENDERS.

         Section 15.17 Joint and Several Liability. All Loans, upon funding,
shall be deemed to be jointly funded to and received by the Borrowers. Each Loan
Party jointly and severally agrees to pay, and shall be jointly and severally
liable under this Agreement for, all Obligations (excluding Existing Obligations
in the case of a Newly Obligated Party), regardless of the manner or amount in
which

LOAN AND SECURITY AGREEMENT - Page 118

<PAGE>   126

proceeds of Loans are used, allocated, shared or disbursed by or among the Loan
Parties themselves, or the manner in which the Agent and/or any Lender accounts
for such Loans or other extensions of credit on its books and records. The
Borrowers acknowledge and expressly agree with the Agent and each Lender that
the joint and several liability of each Borrower is required solely as a
condition to, and is given solely as inducement for and in consideration of,
credit or accommodations extended or to be extended under the Loan Documents to
any or all of the other Loan Parties and is not required or given as a condition
of extensions of credit to such Borrower. Each Loan Party's obligations under
this Agreement and as an obligor under a Guaranty Agreement shall be separate
and distinct obligations. Each Loan Party's obligations under this Agreement
shall, to the fullest extent permitted by law, be unconditional irrespective of
(i) the validity or enforceability, avoidance, or subordination of the
Obligations of any other Loan Party or of any promissory note or other document
evidencing all or any part of the Obligations of any other Loan Party, (ii) the
absence of any attempt to collect the Obligations from any other Loan Party, any
other guarantor, or any other security therefor, or the absence of any other
action to enforce the same, (iii) the waiver, consent, extension, forbearance,
or granting of any indulgence by the Agent and/or any Lender with respect to any
provision of any instrument evidencing the Obligations of any other Loan Party,
or any part thereof, or any other agreement now or hereafter executed by any
other Loan Party and delivered to the Agent and/or any Lender, (iv) the failure
by the Agent and/or any Lender to take any steps to perfect and maintain its
security interest in, or to preserve its rights to, any security or collateral
for the Obligations of any other Loan Party, (v) the Agent's and/or any Lender's
election, in any proceeding instituted under the Bankruptcy Code, of the
application of Section 1111(b)(2) of the Bankruptcy Code, (vi) any borrowing or
grant of a security interest by any other Loan Party, as debtor-in-possession
under Section 364 of the Bankruptcy Code, (vii) the disallowance of all or any
portion of the Agent's and/or any Lender's claim(s) for the repayment of the
Obligations of any other Loan Party under Section 502 of the Bankruptcy Code, or
(viii) any other circumstances which might constitute a legal or equitable
discharge or defense of a guarantor or of any other Loan Party. With respect to
any Loan Party's Obligations arising as a result of the joint and several
liability of the Loan Parties hereunder with respect to Loans or other
extensions of credit made to any of the other Loan Parties hereunder, such Loan
Party waives, until the Obligations shall have been paid in full and the Loan
Agreement shall have been terminated, any right to enforce any right of
subrogation or any remedy which the Agent and/or any Lender now has or may
hereafter have against any other Loan Party, any endorser or any guarantor of
all or any part of the Obligations, and any benefit of, and any right to
participate in, any security or collateral given to the Agent and/or any Lender
to secure payment of the Obligations or any other liability of any Loan Party to
the Agent and/or any Lender. Upon any Event of Default, the Agent may proceed
directly and at once, without notice, against any Loan Party to collect and
recover the full amount, or any portion of the Obligations, without first
proceeding against any other Loan Party or any other Person, or against any
security or collateral for the Obligations. Each Loan Party consents and agrees
that the Agent shall be under no obligation to marshal any assets in favor of
any Loan Party or against or in payment of any or all of the Obligations.

         Section 15.18 Contribution and Indemnification among the Loan Parties.
To the extent that any Loan Party or any Subsidiary of a Loan Party shall repay
any of the Obligations (an "Accommodation Payment"), then the Loan Party or such
Subsidiary making such Accommodation Payment shall be entitled to contribution
and indemnification from, and be reimbursed by, each of the

LOAN AND SECURITY AGREEMENT - Page 119

<PAGE>   127

other Loan Parties in an amount, for each of such other Loan Parties, equal to a
fraction of such Accommodation Payment, the numerator of which fraction is such
other Loan Party's Allocable Amount (as defined below) and the denominator of
which is the sum of the Allocable Amounts of all of the Loan Parties. As of any
date of determination, the "Allocable Amount" of each Loan Party shall be equal
to the maximum amount of liability for Accommodation Payments which could be
asserted against such Loan Party hereunder without (a) rendering such Loan Party
"insolvent" within the meaning of Section 101 (31) of the Bankruptcy Code,
Section 2 of the Uniform Fraudulent Transfer Act ("UFTA") or Section 2 of the
Uniform Fraudulent Conveyance Act ("UFCA"), (b) leaving such Loan Party with
unreasonably small capital or assets, within the meaning of Section 548 of the
Bankruptcy Code, Section 4 of the UFTA, or Section 5 of the UFCA, or (c) leaving
such Loan Party unable to pay its debts as they become due within the meaning of
Section 548 of the Bankruptcy Code or Section 4 of the UFTA, or Section 5 of the
UFCA. All rights and claims of contribution, indemnification, and reimbursement
under this section shall be subordinate in right of payment to the prior payment
in full of the Obligations. The provisions of this section shall, to the extent
expressly inconsistent with any provision in any Loan Document, supersede such
inconsistent provision.

         Section 15.19 Express Waivers By Loan Parties In Respect of Cross
Guaranties and Cross Collateralization. Each Loan Party agrees as follows:

                  (a) Each Loan Party hereby waives: (1) notice of acceptance of
         this Agreement; (2) notice of the making of any Loans, the issuance of
         any Letter of Credit or any other financial accommodations made or
         extended under the Loan Documents or the creation or existence of any
         Obligations; (3) notice of the amount of the Obligations, subject,
         however, to such Loan Party's right to make inquiry of the Agent to
         ascertain the amount of the Obligations at any reasonable time; (4)
         notice of any adverse change in the financial condition of any other
         Loan Party or of any other fact that might increase such Loan Party's
         risk with respect to such other Loan Party under the Loan Documents;
         (5) notice of presentment for payment, demand, protest and notice
         thereof as to any promissory notes or other instruments among the Loan
         Documents; and (6) all other notices (except if such notice is
         specifically required to be given to such Loan Party hereunder or under
         any of the other Loan Documents to which such Loan Party is a party)
         and demands to which such Loan Party might otherwise be entitled;

                  (b) Each Loan Party hereby waives the right by statute or
         otherwise to require the Agent or any Lender to institute suit against
         any other Loan Party or to exhaust any rights and remedies which the
         Agent or any Lender has or may have against any other Loan Party. Each
         Loan Party further waives any defense arising by reason of any
         disability or other defense of any other Loan Party (other than the
         defense that the Obligations shall have been fully and finally
         performed and indefeasibly paid) or by reason of the cessation from any
         cause whatsoever of the liability of any such Loan Party in respect
         thereof.

                  (c) Each Loan Party hereby waives and agrees not to assert
         against the Agent, any Lender or the Letter of Credit Issuer: (i) any
         defense (legal or equitable), set-off, counterclaim or claim which such
         Loan Party may now or at any time hereafter have against any other Loan

LOAN AND SECURITY AGREEMENT - Page 120

<PAGE>   128

         Party or any other party liable under the Loan Documents; (ii) any
         defense, set-off, counterclaim or claim of any kind or nature available
         to any other Loan Party against the Agent, any Lender or the Letter of
         Credit Issuer, arising directly or indirectly from the present or
         future lack of perfection, sufficiency, validity or enforceability of
         the Obligations or any security therefor; (iii) any right or defense
         arising by reason of any claim or defense based upon an election of
         remedies by the Agent, any Lender or the Letter of Credit Issuer under
         any applicable law; (iv) the benefit of any statute of limitations
         affecting any other Loan Party's liability hereunder;

                  (d) Each Loan Party consents and agrees that, without notice
         to or by such Loan Party and without affecting or impairing the
         obligations of such Loan Party hereunder, the Agent may (subject to any
         requirement for consent of any of the Lenders to the extent required by
         this Agreement), by action or inaction: (a) compromise, settle, extend
         the duration or the time for the payment of, or discharge the
         performance of, or may refuse to or otherwise not enforce the Loan
         Documents; (b) release all or any one or more parties to any one or
         more of the Loan Documents or grant other indulgences to any other Loan
         Party in respect thereof; (c) amend or modify in any manner and at any
         time (or from time to time) any of the Loan Documents; or (d) release
         or substitute any Person liable for payment of the Obligations, or
         enforce, exchange, release or waive any security for the Obligations or
         any Guaranty of the Obligations;

                  (e) Each Loan Party represents and warrants to the Agent and
         the Lenders that such Loan Party is currently informed of the financial
         condition of all other Loan Parties and all other circumstances which a
         diligent inquiry would reveal and which bear upon the risk of
         nonpayment of the Obligations. Each Loan Party further represents and
         warrants that such Loan Party has read and understands the terms and
         conditions of the Loan Documents. Each Loan Party agrees that neither
         the Agent, nor any Lender nor the Letter of Credit Issuer has any
         responsibility to inform any Loan Party of the financial condition of
         any other Loan Party or of any other circumstances which bear upon the
         risk of nonpayment or nonperformance of the Obligations.

         Section 15.20 Exception to Covenants. No Loan Party nor any Subsidiary
shall be deemed to be permitted to take any action or fail to take any action
which is permitted as an exception to any of the covenants contained herein or
which is within the permissible limits of any of the covenants contained herein
if such action or omission would result in the breach of any other covenant
contained herein.

         Section 15.21 Judgment Currency. The payment obligations of any Loan
Party under this Agreement or any of the other Loan Documents shall not be
discharged by an amount paid in any currency other than Dollars, or in any other
place than required by this Agreement or any such Loan Documents, to the extent
that the amount so paid on conversion to Dollars and transferred to the Agent in
Dallas, Dallas County, Texas under normal banking procedures does not yield the
amount of Dollars due under this Agreement or any such other Loan Document. If
for the purpose of obtaining judgment in any court it is necessary to convert a
sum due under this Agreement or any of the other Loan Documents in any currency
to another currency (the "Other Currency"), then the rate

LOAN AND SECURITY AGREEMENT - Page 121

<PAGE>   129

of exchange which shall be applied shall be the Spot Rate, determined as of the
Business Day preceding the date on which such judgment is signed by the judge or
other Person acting on behalf of such court. The payment obligations of any Loan
Party in respect of any such amount due by it pursuant to such judgment,
notwithstanding the rate of exchange actually applied in rendering such
judgment, shall be discharged only to the extent that on the Business Day
following receipt by the Agent or the Lenders of any such sum in the Other
Currency pursuant to such judgment, the Agent or the Lenders may, in accordance
with normal banking procedures, purchase and transfer to Dallas, Dallas County,
Texas, Dollars with the amount of the Other Currency so received. As used
herein, "Spot Rate" means, as of any date of determination with respect to the
conversion of an amount denominated in one currency (the "Original Currency") to
the Other Currency, the rate of exchange at which, in accordance with customary
banking procedures and at such time and in such foreign exchange market as the
Agent shall determine consistent with such procedures, the Agent on such date
could purchase such amount of the Original Currency with the Other Currency.

         Section 15.22 Agency of the Parent for each other Loan Party. Each of
the other Loan Parties irrevocably appoints the Parent as its agent for all
purposes relevant to this Agreement, including the giving and receipt of notices
and execution and delivery of all documents, instruments and certificates
contemplated herein (including without limitation execution and delivery to the
Agent of Borrowing Base Certificates, Notices of Borrowing and Notices of
Conversion/Continuation) and all modifications hereto. Any acknowledgment,
consent, direction, certification or other action which might otherwise be valid
or effective only if given or taken by all or any of the Loan Parties or acting
singly, shall be valid and effective if given or taken only by the Parent,
whether or not any of the other Loan Parties joins therein, and the Agent and
the Lenders shall have no duty or obligation to make further inquiry with
respect to the authority of the Parent under this Section 15.22, provided, that
nothing in this Section 15.22 shall limit the effectiveness of, or the right of
the Agent and the Lenders to rely upon, any notice (including without limitation
a Notice of Borrowing), document, instrument, certificate, acknowledgment,
consent, direction, certification or other action delivered by any Borrower
pursuant to this Agreement.

         THIS WRITTEN LOAN AND SECURITY AGREEMENT REPRESENTS 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.

                    PARKER DRILLING COMPANY AND SUBSIDIARIES
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Note 1 - Summary of Significant Accounting Policies

Consolidation - The consolidated financial statements include the accounts of
Parker Drilling Company ("Parker Drilling") and all of its majority-owned
subsidiaries (collectively, the "Company").

     Operations - The Company provides land and offshore contract drilling
services and rental tools on a worldwide basis to major, independent and foreign
national oil companies. Parker's rig fleet consists of 34 barge drilling and
workover rigs, eight offshore jackup rigs, six offshore platform rigs and 75
land rigs. The Company specializes in the drilling of deep and difficult wells,
drilling in remote and harsh environments, drilling in transition zones and
offshore waters and in providing specialized rental tools. The Company also
provides a range of services that are ancillary to its principal drilling
services, including engineering, logistics and construction, as well as various
types of project management.

     Drilling Contracts - The Company recognizes revenue and expenses on dayrate
contracts as the drilling progresses (percentage-of-completion method) because
the Company does not bear the risk of completion of the well. For meterage
contracts, the Company recognizes the revenue and expenses upon completion of
the well (completed-contract method).

     Cash and Cash Equivalents - For purposes of the balance sheet and the
statement of cash flows, the Company considers cash equivalents to be all highly
liquid debt instruments that had a remaining maturity of three months or less at
the date of purchase.

     Other Short-term Investments - Other short-term investments include
primarily certificates of deposit, U.S. government securities and commercial
paper having remaining maturities of greater than three months at the date of
purchase and are stated at the lower of cost or market.

     Property, Plant and Equipment - The Company provides for depreciation of
property, plant and equipment primarily on the straight-line method over the
estimated useful lives of the assets after provision for salvage value. In the
third quarter of fiscal 1998, the Company reviewed the estimated useful life of
its land drilling fleet used for financial depreciation purposes. As a result,
the estimated life was extended from 10 to 15 years with a five percent salvage
value for most of the major rig components. The Company's historical experience
and a comparison with other firms in the industry indicates that its land
drilling equipment has a useful life of at least 15 years. The depreciable lives
for offshore drilling equipment, 15 to 20 years, remained unchanged. The
depreciable lives for certain other equipment, ranging from three to seven
years, including drill pipe, also were not extended. The Company estimates the
change in depreciable lives will result in a reduction in calendar 1999
depreciation expense of $5.2 million. When properties are retired or otherwise
disposed of, the related

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (continued)

Note 1 - Summary of Significant Accounting Policies (continued)

cost and accumulated depreciation are removed from the accounts and any gain or
loss is included in operations. Management periodically evaluates the Company's
assets to determine if they are not in excess of their net realizable value.
Management considers a number of factors such as estimated future cash flows,
appraisals and current market value analysis in determining net realizable
value. Assets are written down to reflect any decrease in net realizable value
below their net carrying value. In addition, interest charges totaling
approximately $3.0 million for the seven months ended July 31, 1999, $1.7
million for the four months ended December 31, 1998 and $3.5 million for the
fiscal year ended August 31, 1998 were capitalized.

     Goodwill - Goodwill is being amortized on a straight-line basis over 30
years commencing on the dates of the respective acquisitions. The Company
assesses whether the excess of cost over net assets acquired is impaired based
on the ability of the operation to which it relates to generate cash flows in
amounts adequate to cover the future amortization of such assets. If an
impairment is determined, the amount of such impairment is calculated based on
the estimated fair value of the related assets.

     Rig Materials and Supplies - Since the Company's foreign drilling generally
occurs in remote locations, making timely outside delivery of spare parts
uncertain, a complement of parts and supplies is maintained for each rig either
at the drilling site or in warehouses close to the operations. During periods of
high rig utilization, these parts are generally consumed and replenished within
a one-year period. During a period of lower rig utilization in a particular
location, the parts, like the related idle rigs, are generally not transferred
to other foreign locations until new contracts are obtained because of the
significant transportation costs which would result from such transfers. The
Company classifies those parts which are not expected to be utilized in the
following year as long-term assets. These assets are carried at the lower of
cost or market.

     Other Long-term Obligations - Included in this account is the accrual of
workers' compensation and deferred revenue related to prepayments received for
certain daywork drilling revenues. These prepayments are recognized over the
related contract term.

     Income Taxes - The Company has adopted Statement of Financial Accounting
Standards (SFAS) No. 109, "Accounting for Income Taxes." Under this method,
deferred tax liabilities and assets are determined based on the difference
between the financial statement and tax basis of assets and liabilities using
enacted tax rates in effect for the year in which the differences are expected
to reverse.

     Earnings (Loss) Per Share (EPS) - The Company has adopted Statement of
Financial Accounting Standard No. 128, "Earnings per Share." The statement
requires a presentation of both basic and diluted EPS. Basic earnings (loss) per
share is computed by dividing net income (loss), as adjusted for dividends on
preferred stock, by the weighted average number of common shares outstanding
during the period. The effect of dilutive securities is included in the diluted
EPS calculation when applicable.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (continued)

Note 1 - Summary of Significant Accounting Policies (continued)

     Concentrations of Credit Risk - Financial instruments which potentially
subject the Company to concentrations of credit risk consist primarily of trade
receivables with a variety of national and international oil and natural gas
companies. The Company generally does not require collateral on its trade
receivables. Such credit risk is considered by management to be limited, except
as noted in the following, due to the large number of customers comprising the
Company's customer base. The Company places substantially all its
interest-bearing investments with major financial institutions and, by policy,
limits the amount of credit exposure to any one financial institution. In
calendar 1999, the Company increased its allowance for doubtful accounts by $3.2
million as the depressed oil industry conditions have negatively impacted
several of the Company's customers' ability to pay the Company for services
provided.

     The current political and currency instability in Indonesia has created
uncertainty regarding the Company's Indonesian operations. The Company provides
management, technical and training support to an Indonesian-owned drilling
contractor, whose services include the drilling of geothermal wells, related to
power plant projects. Due to the uncertain economic conditions, certain of these
power plant projects have been postponed or delayed. As a result, payments from
a significant customer for services provided by the contractor have been
delayed. The Company and the contractor will vigorously pursue all alternatives
to expedite payment. The Company believes that resolution of this matter will
not have a material adverse effect on the Company's results of operations or
financial position.

     Fair Market Value of Financial Instruments - The carrying amount of the
Company's cash and short-term investments and short-term and long-term debt had
fair values that approximated their carrying amounts.

     Accounting Estimates - The preparation of financial statements in
conformity with generally accepted accounting principles requires management to
make estimates and assumptions that affect the reported amounts of assets and
liabilities and disclosure of contingent assets and liabilities at the date of
the financial statements and the reported amounts of revenues and expenses
during the reporting period. Actual results could differ from those estimates.

Note 2 - Acquisitions

     On December 30, 1997, the Company acquired all of the outstanding capital
stock of Hercules Offshore Corporation, a Texas corporation ("HOC"), and all of
the outstanding capital stock of Hercules Rig Corp., a Texas corporation ("HRC")
and an affiliate of HOC (HOC and HRC being collectively referred to as
"Hercules"), for $195.6 million, including acquisition costs. The purchase
prices for the acquisitions were adjusted for certain debt assumed by the
Company, for capital expenditures incurred subsequent to the purchase agreement
date and for levels of working capital at closing. Hercules owns three
self-erecting platform rigs and seven offshore jackup rigs.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (continued)

Note 2 - Acquisitions (continued)

     The acquisition has been accounted for by the purchase method of
accounting, and the reported financial results include the Hercules operations
from the date of acquisition. The excess of purchase price over the fair values
of the net assets acquired was $83.9 million and has been recorded as goodwill,
which is being amortized on a straight-line basis over 30 years.

     The acquisition of Hercules was primarily funded with proceeds from the
July 1997 issuance of the Company's $175 million 5 1/2% Convertible Subordinated
Notes.

Note 3 - Long-term Debt (continued)

The aggregate maturities of long-term debt for the five years ending December
31, 2003, are as follows (000's): 1999 - $ 41,186; 2000 - $ 696; 2001 - $ 613;
2002 - $ 285 and 2003 - $5.

     The Senior Notes, which mature in 2006, were initially issued in November
1996 and in March 1998 in amounts of $300 million (Series B) and $150 million
(Series C), respectively. The $300 million issuance was sold at a $2.4 million
discount while the $150 million issuance was sold at a premium of $5.7 million.
In May 1998, a registration statement was filed by the Company which offered to
exchange the Series B and C notes for new Series D Senior Notes. The form and
terms of the Series D notes are identical in all material respects to the form
and terms of the Series B and C notes, except for certain transfer restrictions
and registration rights relating to the Series C Notes. All of the Series B and
C notes were exchanged for new Series D notes per this offering. The notes have
an interest rate of 9 3/4% and are guaranteed by substantially all subsidiaries
of Parker Drilling, all of which are wholly owned. The guarantees are joint and
several, full, complete and unconditional. There are currently no restrictions
on the ability of the subsidiaries to transfer funds to Parker Drilling in the
form of cash dividends, loans or advances. Parker Drilling is a holding company
with no operations, other than through its subsidiaries. The non-guarantors are
inconsequential, individually and in the aggregate, to the consolidated
financial statements and separate financial statements of the guarantors are not
presented because management has determined that they would not be material to
investors.

         In anticipation of funding the Hercules acquisition, in July 1997 the
Company issued $175 million of Convertible Subordinated Notes due 2004. The
Notes bear interest at 5.5% payable semi-annually in February and August. The
Notes are convertible at the option of the holder into shares of common stock of
Parker Drilling at $15.39 per share at any time prior to maturity. The Notes
will be redeemable at the option of the Company at any time after July 2000 at
certain stipulated prices.

         The $75 million revolving credit facility under the Company's Senior
Credit Facility is available for working capital requirements, general corporate
purposes and to support letters of credit. At July 31, 1999, $40 million was
outstanding under the revolving credit facility and $6.5 million in letters of
credit had been issued. Availability under the revolving credit facility is
subject to certain borrowing base limitations based on 80% of eligible accounts
receivable plus 50% of supplies in inventory. All advances to the Company under
the revolving credit facility bear interest, at the option of the Company, at
prime to prime plus 0.50% or at l.75% to 2.25% above the one-, two-, three- and
seven-month reserve-adjusted LIBOR rate, depending on the percentage of the
credit facility utilized. The revolving credit facility is collateralized by a
first lien on the Company's accounts receivable and inventory. The revolving
credit facility matures on December 31, 2000.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (continued)

     The Senior Credit Facility also included a $100 million term loan that was
used to partially fund the Mallard and Quail acquisitions. The $90 million which
was outstanding at August 31, 1997 was fully repaid during fiscal 1998, $83
million of which was from proceeds received in March 1998 from the issuance of
the Senior Notes.

         Each of the 9 3/4% Senior Notes, 5 1/2% Convertible Notes and the
Senior Credit Facility contains customary affirmative and negative covenants,
including restrictions on incurrence of debt and sales of assets. The Senior
Credit Facility prohibits payment of dividends and the indenture for the 9 3/4%
Senior Notes restricts the payment of dividends.

Note 4 - Common Stock and Stockholders' Equity

Stock Plans

     The Company's employee, non-employee director and consultant stock plans
are summarized as follows:

     The 1994 Non-Employee Director Stock Option Plan ("Director Plan") provides
for the issuance of options to purchase up to 200,000 shares of the Company's
common stock. The option price per share is equal to the fair market value of a
Parker Drilling share on the date of grant. The term of each option is ten
years, and an option first becomes exercisable six months after the date of
grant. Under the Director Plan, on the first trade day of each calendar year,
each person who is then a non-employee director of the Company will be
automatically granted an option to purchase 5,000 shares of common stock.

     The 1994 Executive Stock Option Plan provides for the granting of a maximum
of 2,400,000 shares to key employees and consultants of the Company and its
subsidiaries through the granting of stock options, stock appreciation rights
and restricted and deferred stock awards. The option price per share may not be
less than 50% of the fair market value of a share on the date the option is
granted, and the maximum term of a non-qualified option may not exceed fifteen
years and the maximum term of an incentive option is ten years.

     The 1997 Stock Plan is a "broad-based" stock plan that provides for the
granting of a maximum of 4,000,000 shares to all employees and consultants of
the Company who in the opinion of the board of directors are in a position to
contribute to the growth, management and success of the Company through the
granting of stock options and restricted stock awards. The option price per
share may not be less than 100% of the fair market value on the date the option
is granted for incentive options and not less than par value of a share of
common stock for non-qualified options. The maximum term of an incentive option
is ten years and the maximum term of a non-qualified option is fifteen years.

     In July 1999, 2,000,000 additional shares were registered with the SEC for
granting under the 1997 Stock Plan. In July 1999, 1,884,000 shares were granted
under this plan, leaving 1,120,500 available for granting under this plan. All
shares have been granted under the 1994 Executive Stock Option Plan and the 1994

Note 4 - Common Stock and Stockholders' Equity (continued)

         The Company has three additional stock plans which provide for the
issuance of stock for no cash consideration to officers and key non-officer
employees. Under two of the plans, each employee receiving a grant of shares may
dispose of 15 percent of his/her grant on each annual anniversary date from the
date of grant for the first four years and the remaining 40 percent on the fifth
year anniversary. These plans have a total of 11,375 shares reserved and
available for granting. Shares granted under the third plan are fully vested no
earlier than 24 months from the effective date of the grant and not later than
36 months. The plan has a total of 1,562,195 shares reserved and available for
granting. 18,000 shares granted in fiscal 1996 were the last shares granted
under these plans.

         The fair market value of the common stock at date of grant which
exceeds the option price of shares granted under any of the plans is recorded as
deferred compensation and amortized to expense over the period during which the
restrictions lapse. Deferred compensation is shown as a deduction from
stockholders' equity. All such costs have been fully amortized as of June 30,
1999.

         During calendar year 1999, the Company has purchased 15,195 shares at
an average price of $4.31 per share from certain of its employees who had
received stock grants under the Company's stock plans. During fiscal 1998, 1997
and 1996, the Company purchased 36,562, 42,875 and 59,347 shares, respectively,
from certain of its employees who had received stock grants under the Company's
stock plans, while no shares were purchased during the four month transition
period ended December 31, 1998. Total shares purchased from employees and
treated as treasury stock are 402,607, 445,482 and 482,044 for the four years
ended August 31, 1998. Currently, 497,239 shares are held in Treasury. The
Company acquired the shares at then current market prices (weighted average
price was $8.28 per share in fiscal 1998, $10.08 per share in fiscal 1997 and
$6.44 per share in fiscal 1996). The proceeds were used to pay the employees'
tax withholding obligations arising from the vesting of shares under the Plans.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (continued)

Note 4 - Common Stock and Stockholders' Equity (continued)

Stockholder Rights Plan

         The Company adopted a stockholder rights plan on June 25, 1998 to
assure that the Company's stockholders receive fair and equal treatment in the
event of any proposed takeover of the Company and to guard against partial
tender offers and other abusive takeover tactics to gain control of the Company
without paying all stockholders a fair price. The rights plan was not adopted in
response to any specific takeover proposal. Under the rights plan, the Company's
Board of Directors declared a dividend of one right to purchase one
one-thousandth of a share of a new series of junior participating preferred
stock for each outstanding share of common stock.

         The rights may only be exercised ten days following a public
announcement that a third party has acquired 15% or more of the outstanding
common shares of the Company or ten days following the commencement of, or
announcement of an intention to make, a tender offer or exchange offer, the
consummation of which would result in the beneficial ownership by a third party
of 15% or more of the common shares. The 15% excludes one institutional
stockholder that currently owns in excess of 15% of the outstanding common
shares of the Company solely as an investment, unless such shareholder acquires
in excess of 20% or otherwise gives notice of its intent to hold said shares to
effect a change of control. When exercisable, each right will entitle the holder
to purchase one one-thousandth share of the new series of junior participating
preferred stock at an exercise price of $30, subject to adjustment. If a person
or group acquires 15% or more of the outstanding common shares of the Company,
each right, in the absence of timely redemption of the rights by the Company,
will entitle the holder, other than the acquiring party, to purchase for $30,
common shares of the Company having a market value of twice that amount.

         The rights, which do not have voting privileges, expire June 30, 2008,
and at the Company's option, may be redeemed by the Company in whole, but not in
part, prior to expiration for $.01 per right. Until the rights become
exercisable, they have no dilutive effect on earnings per share.

Note 5 - Assets Held for Disposition

         In December 1998, the Company determined that its operations in
Argentina do not meet its strategic objectives and, therefore, has decided that
such assets would be actively marketed. The assets in Argentina consist of 13
drilling rigs and inventories related to these rigs. The Company had previously
recognized six of the thirteen rigs as held for sale. The current decision
includes all Argentina assets. Due to depressed industry conditions impairment
losses of $4,055,000 and $2,100,000 were recognized in December 1998 and June
1999, respectively. The net realizable value of the Argentina assets ($6.6
million) is included in other non-current assets.
