the expiration of the LIBOR Period in question. If any LIBOR Period so elected
shall end on a date that is not a Business Day, such LIBOR Period shall instead
end on the next preceding or succeeding Business Day as determined by Agent in
accordance with the then current banking practice in London. Each determination
by Agent of a LIBOR Period shall, in the absence of manifest error, be

11:00 a.m. (London time) on the day that is two (2) London Banking Days
preceding the first day of such LIBOR Loan; provided, however, if the rate
described above does not appear on the Telerate System on any applicable

other page as may replace the LIBO Page on that service for the purpose of
displaying such rates), as of 11:00 a.m. (London Time), on the day that is two
(2) London Banking Days prior to the beginning of such interest period. If both
the Telerate and Reuters systems are unavailable, then the rate for that date
will be determined on the basis of the offered rates for deposits in U.S.
dollars for a period of time comparable to such LIBOR Loan which are offered by
four (4) major banks in the London interbank market at approximately 11:00 a.m.
(London time), on the day that is two (2) London

Banking Days preceding the first day of such LIBOR Loan as selected by Agent.
The principal London office of each of the major London Banks so selected will
be requested to provide a quotation of its U.S. dollar deposit offered rate. If
at least two (2) such quotations are provided, the rate for that date will be
the arithmetic mean of the quotations. If fewer than two quotations are provided
as requested, the rate for that date will be determined on the basis of the
rates quoted for loans in U.S. dollars to leading European banks for a period of
time comparable to such LIBOR Loan offered by major banks in New York City at
approximately 11:00 a.m. (New York City time), on the day that is two (2) London
Banking Days preceding the first day of such LIBOR Loan. In the event that Agent
is unable to obtain any such quotation as provided above, it will be determined
that LIBOR Rate pursuant to a LIBOR Loan cannot be determined. In the event that
the Board of Governors of the Federal Reserve System shall impose a Reserve
Percentage with respect to LIBOR deposits of a Lender then for any period during
which such Reserve Percentage shall apply, LIBOR Rate shall be equal to the
amount determined above divided by an amount equal to 1 minus the Reserve
Percentage.

liabilities" as currently defined in Regulation D, or under any similar or
successor regulation with respect to Eurocurrency liabilities or Eurocurrency
funding. Each determination by Agent of the LIBOR Reserve Requirement shall be

binding. Any LIBOR Reserve Requirement shall be determined in accordance with
Agent's customary practice and applied on a consistent basis.

shall be deemed to be ratified by, consented to and also delivered by the other
Borrower. Each Borrower recognizes and agrees that each covenant and agreement
of "Borrower" or "Borrowers" under this Agreement and the Other Agreements shall
create a joint and several obligation of the Borrowers, which may be enforced
against Borrowers, jointly, or against each Borrower separately. Without
limiting the terms of this Agreement and the Other Agreements, security
interests granted under this Agreement and Other Agreements in properties,
interests, assets and collateral shall extend to the properties, interests,
assets and collateral of each Borrower. Similarly, the term "Obligations" shall
include, without limitation, all obligations, liabilities and indebtedness of
such corporations, or any one of them, to Lender, whether such obligations,
liabilities and indebtedness shall be joint, several, joint and several or
individual.

                           ARTICLE 2. CREDIT FACILITY

         Subject to the terms and conditions of, and in reliance upon the
representations and warranties made in, this Agreement and the other Loan
Documents, each Lender agrees severally and not jointly to make its percentage
share of a total credit facility of up to Sixty Million Dollars ($60,000,000.00)
available upon Borrower's request therefor, as follows:

         Section 2.1 Revolving Loans.

         (a)      Subject to all of the terms and conditions of this Agreement,
                  Lenders agree, for so long as no Event of Default exists, to
                  make Revolving Loans to Borrower from time to time, as
                  requested by Borrower in accordance with the terms of Section
                  2.4, up to a maximum principal amount at any time outstanding
                  equal to the Borrowing Base at such time. No Lender shall be
                  required to make any Revolving Loan in excess of its
                  commitment as set forth in Schedule 1 hereto. It is expressly
                  understood and agreed that Lenders shall use the Borrowing
                  Base as a



                                       21


                  maximum ceiling on Revolving Loans outstanding to Borrower at
                  any time, subject to the provisions of Section 2.3. If the
                  unpaid balance of the Revolving Loans should exceed the
                  Borrowing Base or any other limitation set forth in this
                  Agreement, such Revolving Loans shall nevertheless constitute
                  Obligations that are secured by the Collateral and entitled to
                  all the benefits thereof; provided, however, if such an
                  overadvance occurs, Borrower shall immediately repay, without
                  premium or penalty, Revolving Loans in an amount equal to such
                  excess, along with accrued unpaid interest on the amount so
                  repaid to the date of such repayment. In no event shall
                  Borrower be authorized to request a Revolving Loan at any time
                  that there exists an Event of Default.

         (b)      Notwithstanding the foregoing provisions of Section 2.1(a),
                  Lenders shall have the right to establish reserves in such
                  amounts, and with respect to such matters, as Lenders shall
                  deem necessary or appropriate, against the amount of Revolving
                  Loans which Borrower may otherwise request under Section
                  2.1(a), including, without limitation, with respect to (i)
                  price adjustments, damages, unearned discounts, returned
                  products or other matters for which credit memoranda are
                  issued in the ordinary course of Borrower's business; (ii)
                  other sums chargeable against Borrower's Loan Account as
                  Revolving Loans under any section of this Agreement; (iii)
                  sales tax liabilities; (iv) price adjustments, damages,
                  returned products or other matters related to contractual
                  obligations of Borrower; (v) offset exposure relating to
                  contractual obligations of Borrower; and (vi) such other
                  matters, events, conditions or contingencies as to which
                  Lenders, in their credit judgment, determine reserves should
                  be established from time to time hereunder.

         (c)      The Revolving Loans shall be used solely for (i) the payment
                  of costs, expenses and fees relating to the Loans to be made
                  under this Agreement, (ii) the purchase of the capital stock
                  of Borrower, and (iii) Borrower's general operating capital
                  needs, to the extent not inconsistent with the provisions of
                  this Agreement.

         Section 2.2 Vessel Sublimit. If Borrower sells any Vessel or if any
Vessel is a total or constructive total loss, the Vessel Sublimit shall be
reduced by an amount equal to the appraised value of such Vessel according to
the most recent appraisal thereof.

         Section 2.3 Overadvances. Insofar as Borrower may request and Fleet may
be willing in its sole and absolute discretion to make Revolving Loans to
Borrower at a time when the unpaid balance of Revolving Loans exceeds, or would
exceed with the making of any such Revolving Loan, the Borrowing Base (any such
Loan or Loans being herein referred to individually as an "Overadvance" and
collectively as "Overadvances"), Fleet may make such Overadvances in amount not
to exceed USD 1,000,000 at any time outstanding, and the Agent shall enter such
Overadvances as debits in the Loan Account. All Overadvances shall be repaid on
demand, shall be secured by the Collateral and shall bear interest as provided
in this Agreement for Revolving Loans generally, and shall be subject to the
terms of Section 2.9(d) hereof with respect to Agent Advances. The foregoing
notwithstanding, in no event, unless otherwise consented to by the Agent, shall
any Overadvances be outstanding for more than thirty (30) consecutive days.


                                       22



         Section 2.4 Manner of Borrowing. Borrowings under the Revolving Credit
Commitment shall be as follows:

         (a)      A request for a LIBOR Loan shall be made, or shall be deemed
                  to be made, if Borrower gives Agent notice of its intention to
                  borrow in the form of Exhibit B (a "Borrowing Notice"), in
                  which notice Borrower shall specify (i) the aggregate amount
                  of such LIBOR Loan, (ii) the requested date of such LIBOR
                  Loan, (iii) the Applicable Annual Rate selected in accordance
                  with Section 3.1, and (iv) the LIBOR Period applicable
                  thereto. If Borrower selects a LIBOR Loan, Borrower shall give
                  Agent the Borrowing Notice at least two (2) Business Days
                  prior to the requested date of the LIBOR Loan.

         (b)      A request for a Base Rate Loan shall be made, or shall be
                  deemed to be made, if (i) Borrower sends by facsimile
                  transmission to (214) 706-7079, or such other number as Agent
                  may designate, a request for a Base Rate Loan prior to 12:00
                  p.m. Central Standard Time on the Business Day on which
                  Borrower is requesting such Base Rate Loan (if a request is
                  received after such time on a Business Day, Agent, in its sole
                  discretion, may request the Lenders to make the requested Base
                  Rate Loan on the day of such notice or on the next following
                  Business Day); (ii) Borrower fails to pay any interest
                  accruing under this Agreement or the Notes on the date such
                  interest becomes due and payable, or (iii) Borrower fails to
                  pay any other Obligations under this Agreement on the date
                  such Obligations become due and payable. The amount of Base
                  Rate Loans advanced according to clause (i) shall be for the
                  amount requested. The amount of Base Rate Loans advanced
                  according to clauses (ii) and (iii) shall be deemed to be an
                  amount equal to the amount of interest that was not actually
                  paid by Borrower or the amount of funds actually disbursed,
                  respectively.

         (c)      Borrower hereby irrevocably authorizes Lenders to disburse the
                  proceeds of each Loan requested, or deemed to be requested,
                  pursuant to this Section 2.4 as follows: (i) the proceeds of
                  each Loan requested under Sections 2.4(a) or 2.4(b)(i) shall
                  be disbursed by Lenders in lawful money of the United States
                  of America in immediately available funds, in the case of the
                  initial borrowing, in accordance with the terms of the written
                  disbursement letter from Borrower, and in the case of each
                  subsequent borrowing, by wire transfer to such bank account as
                  may be agreed upon by Borrower and Agent from time to time;
                  and (ii) the proceeds of each Revolving Loan requested under
                  Section 2.4(b)(ii) or (iii) shall be disbursed by Lenders by
                  way of direct payment of the relevant Obligation.

         Section 2.5 Letters of Credit; LC Guaranties.


                                       23

                           Outstandings would exceed the LC Facility then in
                           effect or (B) the aggregate principal amount of the
                           Revolving Credit Loans outstanding would exceed the
                           Borrowing Base (after reduction for the LC Reserve in
                           respect of such Letter of Credit) or (C) if no
                           Revolving Credit Loans are outstanding, the aggregate
                           LC Outstandings would exceed the Borrowing Base; or

                           expiration date after the 30th day prior to the last

         (c)      Conditions. The obligation of Fleet to procure a Letter of

                           Fleet, the Issuing Bank and Agent for the issuance of
                           such Letter of Credit and such other LC Documents as

                           completed and signed LC Application (unless Fleet is
                           to join in such LC Application, in which case it
                           shall be signed by Borrower and completed but for any
                           information to be supplied by Fleet), to Fleet,
                           Issuing Bank and Agent no later than three (3)
                           Business Days prior to the proposed date of issuance
                           of the requested Letter of Credit. Such notice shall

                           amount of the Letter of Credit requested, the
                           effective date (which date shall be a Business Day)
                           of issuance of such requested Letter of Credit,
                           whether such Letter of Credit may be drawn in a
                           single or in multiple draws, the date on which such
                           requested Letter of Credit is to expire (which date
                           shall be a Business Day prior to the last day of the
                           Term), the purpose for which such Letter of Credit is
                           to be issued and the beneficiary of the requested
                           Letter of Credit.

                  (ii)     Responsibilities of the Agent; Issuance. Agent shall

                           Application, the amount of the unused LC Facility and
                           the Borrowing Base. If (A) the form of the Letter of
                           Credit delivered by Borrower to Agent is acceptable
                           to Fleet, the Issuing Bank and Agent in their sole
                           discretion, (ii) the undrawn available amount of the
                           requested Letter of Credit is less than or equal to
                           the lesser of (A) the unused LC Facility, and (B) the
                           unused Borrowing Base and (iii) Agent has received a
                           certificate from Borrower stating that the applicable
                           conditions set forth in Section 9 have been
                           satisfied, then Fleet will cause the Letter of Credit
                           to be issued.

                  (iii)    Notice of Issuance. Fleet shall give Agent written or
                           facsimile notice, or telephonic notice confirmed
                           promptly thereafter in writing, of the issuance of
                           each Letter of Credit and related LC Guaranty, and
                           Agent shall give each Lender periodic notice of the
                           issuance of each Letter of Credit and related LC
                           Guaranty and Agent shall provide the Lenders at least
                           monthly with a report of all Letters of Credit and LC
                           Guaranties outstanding.

                  (iv)     No Extension or Amendment. No Letter of Credit nor LC
                           Guaranty shall be extended or amended unless the
                           requirements of this Section 2.5(d) are met as though
                           a new Letter of Credit were being requested and
                           issued.

         (e)      Duties of Issuing Bank. The rights and obligations of Borrower
                  and the Issuing Bank in respect of any Letter of Credit shall
                  be governed by the LC Application and other LC Documents
                  pursuant to which such Letter of Credit was issued. No action
                  taken or omitted to be taken by the Issuing Bank under or in
                  connection with any Letter of Credit shall result in any
                  liability of Fleet or the Agent to the Loan Parties or any
                  Lender or relieve the Borrower or any Lender of its
                  obligations hereunder to Fleet, including in respect of the
                  related LC Guaranty. In determining whether to reimburse an
                  amount drawn under any Letter of Credit, Fleet shall have no
                  obligation to any Borrower or any Lender other than to confirm
                  that such drawing has been honored by the Issuing Bank.



                                       25


         (f)      Payment of Reimbursement Obligations.

                  (i)      Payment. Notwithstanding any provisions to the
                           contrary in any LC Application or other LC Document,
                           Borrower agrees to reimburse the Issuing Bank for any
                           drawings (whether partial or full) under each Letter
                           of Credit issued by the Issuing Bank and agrees to
                           pay to the Issuing Bank the amount of all other LC
                           Outstandings and other amounts payable to the Issuing
                           Bank under or in connection with such Letter of
                           Credit immediately when due and (but without
                           duplication) to pay or to reimburse Fleet on demand
                           for any amounts payable or paid by Fleet under any LC
                           Guaranty, irrespective of any claim, set-off, defense
                           or other right which any Loan Party may have at any
                           time against the Issuing Bank, Fleet or any other
                           Person.

                  (ii)     Recovery or Avoidance of Payments. In the event any
                           payment by or on behalf of any Loan Party with
                           respect to any Letter of Credit or related LC
                           Guaranty received by the Issuing Bank, Fleet, or
                           Agent and distributed by Agent to the Lenders on
                           account of their respective participations therein,
                           is thereafter set aside, avoided or recovered from
                           the Issuing Bank, Fleet or Agent in connection with
                           any receivership, liquidation or bankruptcy
                           proceeding or otherwise, the Lenders shall, upon
                           demand by the Agent, pay to Agent, for the account of
                           the Issuing Bank, Fleet or the Agent their respective
                           Revolving Credit Percentage of such amount set aside,
                           avoided or recovered together with interest at the
                           rate required to be paid by Agent on the amount
                           required to be repaid by it.

         (g)      Participations.

                  (i)      Purchase of Participations. Immediately upon issuance
                           by Fleet of an LC Guaranty, each Lender shall be
                           deemed to have irrevocably and unconditionally
                           purchased and received without recourse or warranty,
                           an undivided interest and participation in such LC
                           Guaranty, equal to such Lender's Revolving Credit
                           Percentage of the face amount thereof, and any
                           security therefor or guaranty pertaining thereto,
                           including any rights of Fleet on payment thereunder
                           to be subrogated to the rights of the Issuing Bank
                           under the related Letter of Credit.

                  (ii)     Sharing of Letter of Credit Payments. In the event
                           that Fleet makes a payment under any LC Guaranty and
                           Fleet shall not have been repaid such amount pursuant
                           to Section 2.5(f), then on a weekly basis, or more
                           frequently if requested by Fleet, each Lender shall
                           make payment to Fleet, in immediately available
                           funds, of an amount equal to such Lender's pro rata
                           share of the amount of any payment made by Fleet in
                           respect of any LC Guaranty. The obligation of each
                           Lender to reimburse Fleet under this Section 2.5(g)
                           shall be unconditional, continuing, irrevocable and
                           absolute. In the event that any Lender fails to make
                           payment to Fleet of any amount due under this Section
                           2.5(g), the Agent shall be entitled to



                                       26


                           receive, retain and deliver to Fleet for application
                           against such obligation the principal and interest
                           otherwise payable to such Lender hereunder until
                           Fleet receives such payment from such Lender or such
                           obligation is otherwise fully satisfied.

                  (iii)    Sharing of Reimbursement Obligation Payments.
                           Whenever Fleet receives a payment from or on behalf
                           of Borrower on account of a reimbursement obligation
                           under an LC Guaranty, Fleet shall promptly pay to
                           Agent, for the benefit of each Lender that has
                           previously paid its pro rata share of such amount to
                           or for the benefit of Fleet, such Lender's pro rata
                           share of the amount of such payment from the Borrower
                           in Dollars. Each such payment shall be made by Fleet
                           on the Business Day on which Fleet receives
                           immediately available funds, if received prior to
                           11:00 a.m. (Dallas, Texas time) on such Business Day,
                           and otherwise on the next succeeding Business Day.

                  (iv)     Documentation. Upon the request of any Lender, Agent
                           shall furnish to such Lender copies of any Letter of
                           Credit, LC Application or LC Guaranty for any Letter
                           of Credit and such other documentation as may
                           reasonably be requested by such Lender.

                  (v)      Obligations Irrevocable. The obligations of each
                           Lender to make payments to Agent with respect to any
                           LC Guaranty and their participations therein and the
                           obligations of Borrower to make payments to Fleet or
                           to Agent, for the account of Lenders, shall be
                           irrevocable, shall not be subject to any
                           qualification or exception whatsoever and shall be
                           made in accordance with the terms and conditions of
                           this Agreement (assuming, in the case of the
                           obligations of the Lenders to make such payments,
                           that the LC Guaranty has been issued in accordance
                           with Section 2.5(d).

         (h)      Indemnification, Exoneration.

                  (i)      Indemnification. In addition to amounts payable as
                           elsewhere provided in this Section 2.5, Borrower
                           agrees to protect, indemnify, pay and save the
                           Lenders, Fleet, the Issuing Bank and Agent harmless
                           from and against any and all claims, demands,
                           liabilities, damages, losses, costs, charges and
                           expenses (including reasonable attorneys' fees) which
                           any Lender, Fleet, the Issuing Bank or the Agent may
                           incur or be subject to as a consequence, directly or
                           indirectly, of

                           (A)      the issuance of any Letter of Credit or LC
                                    Guaranty, other than as a result of its
                                    gross negligence or willful misconduct, as
                                    determined by a court of competent
                                    jurisdiction, or

                           (B)      the failure of the Issuing Bank to honor a
                                    drawing under any Letter of Credit as a
                                    result of any act or omission, whether
                                    rightful or



                                       27


                                    wrongful, of any present or future de jure
                                    or de facto governmental authority (all such
                                    acts or omissions being hereinafter referred
                                    to collectively as "Government Acts").

                  (ii)     Assumption of Risk. As among Borrower, Fleet, the
                           Lenders and Agent, Borrower assumes 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 and confirm, for the benefit
                           of Fleet, the Lenders and Agent that as between
                           Borrower and the Issuing Bank, such matters will be
                           subject to the terms of the LC Application and other
                           LC Documents.

                  (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,
                           Fleet, the Issuing Bank or any Lender under or in
                           connection with any of the Letters of Credit, any LC
                           Guaranty or any related agreements, certificates, or
                           other documents, if taken or omitted in good faith,
                           shall not result in any liability of any of Fleet,
                           Lender or the Agent to Borrower or relieve Borrower
                           of any of its obligations hereunder to any such
                           Person.

         (i)      Supporting Letter of Credit; Cash Collateral. If,
                  notwithstanding the provisions of Section 2.5(b), any LC
                  Guaranty is outstanding on the last day of the Term, then on
                  or prior to the last day of the Term, or in any case upon the
                  occurrence of any Default or Event of Default, Borrower shall,
                  promptly on demand by Agent, deposit with Agent, for the
                  ratable benefit of the Lenders, with respect to each LC
                  Guaranty then outstanding, as Agent shall specify, either (a)
                  a standby letter of credit (a "Supporting Letter of Credit")
                  in form and substance satisfactory to Agent, issued by an
                  issuer satisfactory to Agent in its reasonable judgment under
                  which Supporting Letter of Credit Agent is entitled to draw
                  amounts necessary to reimburse Fleet for payments made by
                  Fleet under such LC Guaranty or under any reimbursement or
                  guaranty agreement with respect thereto or any Letter of
                  Credit issued for the account of Borrower, or (b) Cash
                  Collateral, in either case with respect to the foregoing
                  clauses (a) or (b), in an amount equal to 105% of the greatest
                  amount for which the Letter of Credit relating to such LC
                  Guaranty may be drawn plus all related costs then accrued or
                  which may be incurred or which may in the future accrue. Such
                  Supporting Letter of Credit or Cash Collateral shall be held
                  by Agent, as security for, and to provide for the payment of,
                  Borrower's obligations in respect of such outstanding LC
                  Guaranty or under any reimbursement or guaranty agreement with
                  respect thereto or any Letter of Credit issued for the account
                  of Borrower in an amount necessary to reimburse Fleet for
                  payments made by Fleet. In addition, Agent may at any time
                  after the last day of the Term apply any or all of such Cash
                  Collateral to the payment of any or all of the Obligations
                  then due and payable. At Borrower's request, but subject to
                  Agent's reasonable approval, Agent shall invest any Cash
                  Collateral consisting of cash or any proceeds of Cash
                  Collateral consisting of cash, in Cash Equivalents, and any
                  commissions, expenses and penalties incurred by Agent in
                  connection with any investment and redemption of such Cash
                  Collateral shall be Obligations hereunder secured by the
                  Collateral, shall bear interest at the rates provided herein



                                       28


                  for the Revolving Credit Base Loan and shall be charged to the
                  Loan Account of the Borrower, or, at Agent's option, shall be
                  paid out of the proceeds of any earnings received by Agent
                  from the investment of such Cash Collateral as provided herein
                  or out of such cash itself. Agent makes no representation or
                  warranty as to, and shall not be responsible for, the rate of
                  return, if any, earned on any Cash Collateral. Any earnings on
                  Cash Collateral shall be held as additional Cash Collateral on
                  the terms set forth in this Section 2.5(i).

         Section 2.6 All Loans to Constitute One Obligation. All Loans shall
constitute one general joint and several obligation of Borrowers, shall be
evidenced by the Notes, and shall be secured by Agent's security interest in and
Lien upon all of the Collateral, and by all other security interests and Liens
heretofore, now or at any time or times hereafter granted by Borrower to Agent.

         Section 2.7 Loan Account. Lenders shall enter all Loans as debits to
the Loan Account and shall also record in the Loan Account all payments made by
Borrowers on each Loan and all proceeds of Collateral which are finally paid to
Lenders, and may record therein, in accordance with customary accounting
practices, all charges and expenses properly chargeable to Borrower hereunder.

         Section 2.8 Joint and Several Liability: Rights of Contribution.

         (a)      Each Borrower states and acknowledges that: (i) pursuant to
                  this Agreement, Borrowers desire to utilize their borrowing
                  potential on a consolidated basis to the same extent possible
                  if they were merged into a single corporate entity; (ii) it
                  has determined that it will benefit specifically and
                  materially from the advances of credit contemplated by this
                  Agreement; (iii) it is both a condition precedent to the
                  obligations of Lenders hereunder and a desire of the Borrowers
                  that each Borrower execute and deliver to Agent and Lenders
                  this Agreement; and (iv) Borrowers have requested and
                  bargained for the structure and terms of and security for the
                  advances contemplated by this Agreement.

         (b)      Each Borrower hereby irrevocably and unconditionally: (i)
                  agrees that it is jointly and severally liable to Lenders for
                  the full and prompt payment of the Obligations and the
                  performance by each Borrower of its obligations hereunder in
                  accordance with the terms hereof; (ii) agrees to fully and
                  promptly perform all of its obligations hereunder with respect
                  to each advance of credit hereunder as if such advance had
                  been made directly to it; and (iii) agrees as a primary
                  obligation to indemnify Lenders on demand for and against any
                  loss incurred by Lenders as a result of any of the obligations
                  of any Borrower being or becoming void, voidable,
                  unenforceable or ineffective for any reason whatsoever,
                  whether or not known to Agent, Lenders or any Person, the
                  amount of such loss being the amount which Lenders would
                  otherwise have been entitled to recover from Borrower.

It is the intent of each Borrower that the indebtedness, obligations and
liability hereunder of no one of them be subject to challenge on any basis.
Accordingly, as of the date hereof, the liability



                                       29



of each Borrower under this Section 2.8, together with all of its other
liabilities to all Persons as of the date hereof and as of any other date on
which a transfer is deemed to occur by virtue of this Agreement, calculated in
amount sufficient to pay its probable net liabilities on its existing
Indebtedness as the same become absolute and matured ("Dated Liabilities") is,
and is to be, less than the amount of the aggregate of a fair valuation of its
property as of such corresponding date ("Dated Assets"). To this end, each
Borrower under this Section 2.8, (i) grants to and recognizes in each other
Borrower, ratably, rights of subrogation and contribution in the amount, if any,
by which the Dated Assets of such Borrower, but for the aggregate of subrogation
and contribution in its favor recognized herein, would exceed the Dated
Liabilities of such Borrower or, as the case may be, (ii) acknowledges receipt
of and recognizes its right to subrogation and contribution ratably from the
other Borrower in the amount, if any, by which the Dated Liabilities of such
Borrower, but for the aggregate of subrogation and contribution in its favor
recognized herein, would exceed the Dated Assets of such Borrower under this
Section 2.8. In recognizing the value of the Dated Assets and the Dated
Liabilities, it is understood that Borrowers will recognize, to at least the
same extent of their aggregate recognition of liabilities hereunder, their
rights to subrogation and contribution hereunder. It is a material objective of
this Section 2.8 that each Borrower recognizes rights to subrogation and
contribution rather than be deemed to be insolvent (or in contemplation thereof)
by reason of an arbitrary interpretation of its joint and several obligations
hereunder.

         Section 2.9 Contribution of Lenders; Non-Ratable Loans

         (a)      Agent's Election. Promptly after receipt of a Borrowing Notice
                  pursuant to Section 2.4, the Agent shall elect, in its
                  discretion, (i) to have the terms of Section 2.9(b) apply to
                  such requested Borrowing, or (ii) to request Fleet to make a
                  Non-Ratable Loan pursuant to the terms of Section 2.9(c) in
                  the amount of the requested Borrowing; provided, however that
                  if Fleet declines in its sole discretion to make a Non-Ratable
                  Loan pursuant to Section 2.9(c) the Agent shall elect to have
                  the terms of Section 2.9(b) apply to such requested Borrowing.

         (b)      Making of Revolving Loans.

                  (i)      In the event that the Agent shall elect to have the
                           terms of this Section 2.9(b) apply to a requested
                           Borrowing as described in Section 2.4, then promptly
                           after receipt of a Borrowing Notice, 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 immediately 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 9, the Agent shall
                           make the proceeds of such Revolving Loans available
                           to the Borrower 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



                                       30


                           to Section 2.4 or disbursing such funds in such other
                           manner as the Borrower may direct to the Agent.

                  (ii)     Unless the Agent receives notice from a Lender at
                           least one Business Day prior to the date of a
                           requested Borrowing, that such Lender will not make
                           available its Pro Rata Share of such 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 required) to make available to the
                           Borrower on such date a corresponding amount. If and
                           to the extent a Lender has not made such amounts
                           available to the Agent, and the Agent has made the
                           Borrowing available to the Borrower, such Lender
                           shall on the Business Day following such Funding Date
                           make such amount available to the Agent, together
                           with interest at the Base Rate for each day during
                           such period. A notice by the Agent submitted to any
                           Lender with respect to such amounts owing under this
                           subsection shall be conclusive, absent manifest
                           error. 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
                           and, upon demand by the Agent, the Borrower will pay
                           such amount to the Agent for Agent's account,
                           together with interest for each day elapsed since the
                           Funding Date at the interest rate then applicable to
                           Revolving Loans. The failure of a Lender to make its
                           Pro Rata Share of a Borrowing available on a Funding
                           Date (a "Defaulting Lender") shall not relieve any
                           other Lender of its obligation to make its Pro Rata
                           Share of such Borrowing on the Funding Date, but
                           neither the Agent nor any Lender shall be responsible
                           for the failure of any other Lender to make its Pro
                           Rata Share of such Borrowing available on such
                           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 the Borrower the amount of all
                           such payments received or retained by it for the
                           account of the Defaulting Lender. Any amounts so
                           re-lent to the Borrower shall bear interest at the
                           rate applicable to Base Rate Loans and for all other
                           purposes of this Agreement shall be treated as
                           Revolving Loans; provided, however, that for purposes
                           of voting or consenting to matters with respect to
                           the Loan Documents and determining a Lender's Pro
                           Rata Share, 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 commitment fee
                           set forth in Section 3.1(f) and (B) such fee shall
                           accrue in favor of the Lenders which have funded
                           their respective Pro Rata Shares of such requested
                           Borrowing land shall be allocated among such
                           performing Lenders ratably based upon their relative
                           Commitments. This Section shall remain



                                       31


                           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 Borrower of its duties and obligations
                           hereunder.

         (c)      Making of Non-Ratable Loans.

                  (i)      In the event the Agent shall elect, with the consent
                           of Fleet, to have the terms of this Section 2.9(c)
                           apply to a requested Borrowing, Fleet shall make a
                           Revolving Loan in the amount of such Borrowing (any
                           such Revolving Loan made solely by Fleet pursuant to
                           this Section 2.9(c) being referred to as a
                           "Non-Ratable Loan" and such Revolving Loans being
                           referred to collectively as "Non-Ratable Loan")
                           available to the Borrower on the Funding Date
                           applicable thereto by transferring same day funds to
                           the account of such Borrower, designated pursuant to
                           Section 2.4. 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
                           Fleet 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 Fleet 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 9 will not be
                           satisfied on the requested Funding Date for the
                           applicable Borrowing, or (B) the requested Borrowing
                           would exceed the Revolving Credit Commitment on such
                           Funding Date. Fleet shall not otherwise be required
                           to determine whether the applicable conditions
                           precedent set forth in Article 9 have been satisfied
                           or the requested Borrowing would exceed the Revolving
                           Credit Commitment 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
                           Collateral, shall constitute Revolving Loans and
                           Obligations hereunder, and shall bear interest at the
                           rate applicable to the Revolving Loans from time to
                           time.

         (d)      Agent Advances.

                  (i)      Subject to the limitations set forth in the provisos
                           contained in this Section 2.9(d), 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
                           9 have not been satisfied, to make Base Rate Loans to
                           the 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



                                       32


                           of, repayment of the Loans and other Obligations, or
                           (3) to pay any other amount chargeable to the
                           Borrower pursuant to the terms of this Agreement,
                           including costs, fees, and expenses as described in
                           Section 12.4 (any of the advances described in this
                           Section 2.9(d) being hereinafter referred to as
                           "Agent Advances"); provided that the Majority Lenders
                           may at any time revoke the Agent's authorization
                           contained in this Section 2.9(d) 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 Collateral, shall constitute Revolving
                           Loans and Obligations hereunder, and shall bear
                           interest at the rate applicable to Base Rate Loans
                           from time to time. The Agent shall notify the
                           Borrower and each Lender in writing of each such
                           Agent Advance; provided that the failure of the Agent
                           to provide any such notice to the Borrower or any
                           Lender shall not affect the Borrower's liability for
                           or obligation to repay such Agent Advances or result
                           in any liability or constitute the breach of any duty
                           or obligation of the Agent hereunder.

         (e)      Settlement. Except as may be specifically provided otherwise
                  by this Section 2.9, 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, Fleet, 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 (a "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 Fleet, with respect to each
                           outstanding Non-Ratable Loan, (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 Fleet, 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



                                       33


                           set forth in Article 9 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 Fleet's Pro Rata Share thereof, shall
                           constitute Revolving Loans of the Lenders,
                           respectively. 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
                           Base 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 Fleet 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 Fleet or the Agent, as applicable, shall
                           pay to Fleet 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
                           interest rate then applicable to Base Rate 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 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 Fleet 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 Fleet's Revolving
                           Loans. If, as of any Settlement Date, collections
                           received since the then immediately preceding
                           Settlement Date have been applied to Fleet's
                           Revolving Loans (other than to Non-Ratable Loans or
                           Agent Advances in which such Lender has not yet
                           funded its



                                       34


                           purchase of a participation pursuant to Section
                           2.9(d)(ii)), as provided for in the previous
                           sentence, Fleet 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, Fleet 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 Fleet, the Agent and the other Lenders.

         (f)      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 Fleet, 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 repayment or prepayment of principal
                  of such Lender's Revolving Loans in its books and records,
                  including computer records, such books and records
                  constituting presumptive evidence, absent manifest error, of
                  the accuracy of the information contained therein.

         (g)      Lenders' Failure to Perform. All Revolving Loans (other than
                  Non-Ratable Loans and Agent Advances) shall be made by the
                  Lenders simultaneously and in accordance with their Pro Rata
                  Shares. It is understood that (i) no Lender shall be
                  responsible for any failure by any other Lender to perform its
                  obligation to make any Revolving Loans hereunder, nor shall
                  any commitment of any Lender be increased or decreased as a
                  result of any failure by any other Lender to perform its
                  obligation to make any Revolving Loans hereunder, (ii) no
                  failure by any Lender to perform its obligation to make any
                  Revolving Loans hereunder shall excuse any other Lender from
                  its obligation to make any Revolving Loans hereunder, and
                  (iii) the obligations of each Lender hereunder shall be
                  several, not joint and several.

            ARTICLE 3. INTEREST, FEES, TERM, REDUCTION AND REPAYMENT

         Section 3.1 Interest, Fees and Charges.

         (a)      Interest. Outstanding principal on the Loans shall bear
                  interest at the option of Borrower (subject to the terms and
                  conditions herein) at either the Base Rate or LIBOR Rate,
                  calculated daily, at the following rates per annum
                  (individually called, as applicable, an "Applicable Annual
                  Rate"):

                  (i)      Existing LIBOR Loans. Each LIBOR Loan outstanding on
                           the date of this Agreement shall bear interest at a
                           rate per annum equal to the existing Applicable
                           Annual Rate.



                                       35


                  (ii)     New LIBOR Loans. Each LIBOR Loan drawn after the
                           Closing Date shall bear interest at a rate per annum
                           equal to the LIBOR Rate plus the Applicable Margin
                           Amount.

                  (iii)    Base Rate Loans. The Base Rate Loans shall bear
                           interest at a fluctuating rate per annum equal to the
                           Base Rate plus the Applicable Margin Amount.

         The interest rate applicable to Base Rate Loans shall be increased or
decreased, as the case may be, by an amount equal to any increase or decrease in
the Base Rate, with such adjustments to be effective as of the opening of
business on the day that any such change in the Base Rate becomes effective. The
Base Rate in effect on the date hereof shall be the Base Rate effective as of
the opening of business on the date hereof, but if this Agreement is executed on
a day that is not a Business Day, the Base Rate in effect on the date hereof
shall be the Base Rate effective as of the opening of business on the last
Business Day immediately preceding the date hereof. Interest on the Loans shall
be calculated daily, based on the actual days elapsed over a three hundred-sixty
(360) day year. Further, for the purpose of computing interest, all items of
payment received by Lenders shall be applied by Lenders (subject to final
payment of all drafts and other items received in form other than immediately
available funds) against the Obligations on the day of receipt. The
determination of when a payment is received by Lenders will be made in
accordance with Section 3.6.

         (b)      Default Rate of Interest. Upon and after the occurrence of an
                  Event of Default, and during the continuation thereof, the
                  principal amount of the Loans and other Obligations shall bear
                  interest, calculated daily (computed on the actual days
                  elapsed over a three hundred-sixty (360) day year), at two
                  percent (2.00%) above the Base Rate or other applicable rate
                  of interest (a "Default Rate").

         (c)      Maximum Rate of Interest. Notwithstanding anything to the
                  contrary in this Agreement or otherwise, (i) if at any time
                  the amount of interest computed on the basis of an Applicable
                  Annual Rate or a Default Rate would exceed the amount of such
                  interest computed upon the basis of the maximum rate of
                  interest permitted by applicable state or federal law in
                  effect from time to time hereafter (the "Maximum Legal Rate"),
                  the interest payable under this Agreement shall be computed
                  upon the basis of the Maximum Legal Rate, but any subsequent
                  reduction in such Applicable Annual Rate or Default Rate, as
                  applicable, shall not reduce such interest thereafter payable
                  hereunder below the amount computed on the basis of the
                  Maximum Legal Rate until the aggregate amount of such interest
                  accrued and payable under this Agreement equals the total
                  amount of interest which would have accrued if such interest
                  had been at all times computed solely on the basis of an
                  Applicable Annual Rate or Default Rate, as applicable; and
                  (ii) unless preempted by federal law, an Applicable Annual
                  Rate or Default Rate, as applicable, from time to time in
                  effect hereunder may not exceed the applicable indicated rate
                  ceiling as defined in the Texas Finance Code, (and as the same
                  may be incorporated by reference in other Texas statutes), but
                  otherwise without limitation, that rate based upon the "weekly
                  rate ceiling" and calculated after taking into account any and
                  all relevant fees, payments, and other charges in



                                       36


                  respect of the Loan which are deemed to be interest under
                  applicable law. If the applicable state or federal law is
                  amended in the future to allow a greater rate of interest to
                  be charged under this Agreement than is presently allowed by
                  applicable state or federal law, then the limitation of
                  interest hereunder shall be increased to the maximum rate of
                  interest allowed by applicable state or federal law as
                  amended, which increase shall be effective hereunder on the
                  effective date of such amendment, and all interest charges
                  owing to Lender by reason thereof shall be payable upon
                  demand. (d) Excess Interest. No agreements, conditions,
                  provisions or stipulations contained in this Agreement or
                  any other instrument, document or agreement between Borrower,
                  Agent and Lenders or default of Borrower, or the exercise by
                  Agent or Lenders of the right to accelerate the payment of the
                  maturity of principal and interest, or to exercise any option
                  whatsoever contained in this Agreement or any other Loan
                  Document, or the arising of any contingency whatsoever, shall
                  entitle Lenders to contract for, charge, or receive, in any
                  event, interest exceeding the Maximum Legal Rate. In no event
                  shall Borrower be obligated to pay interest exceeding such
                  Maximum Legal Rate and all agreements, conditions or
                  stipulations, if any, which may in any event or contingency
                  whatsoever operate to bind, obligate or compel Borrower to pay
                  a rate of interest exceeding the Maximum Legal Rate, shall be
                  without binding force or effect, at law or in equity, to the
                  extent only of the excess of interest over such Maximum Legal
                  Rate. In the event any interest is contracted for, charged or
                  received in excess of the Maximum Legal Rate ("Excess"),
                  Borrower acknowledges and stipulates that any such contract,
                  charge, or receipt shall be the result of an accident and bona
                  fide error, and that any Excess received by Lenders shall be
                  applied, first, to reduce the principal then unpaid hereunder;
                  second, to reduce the other Obligations; and third, returned
                  to Borrower, it being the intention of the parties hereto not
                  to enter at any time into a usurious or otherwise illegal
                  relationship. Borrower recognizes that, with fluctuations in
                  the Base Rate or the LIBOR Rate and the Maximum Legal Rate,
                  such a result could inadvertently occur. By the execution of
                  this Agreement, Borrower covenants that (i) the credit or
                  return of any Excess shall constitute the acceptance by
                  Borrower of such Excess, and (ii) Borrower shall not seek or
                  pursue any other remedy, legal or equitable, against Lenders,
                  based in whole or in part upon contracting for, charging or
                  receiving of any interest in excess of the maximum authorized
                  by applicable law. For the purpose of determining whether or
                  not any Excess has been contracted for, charged or received by
                  Lenders, all interest at any time contracted for, charged or
                  received by Lenders in connection with this Agreement shall be
                  amortized, prorated, allocated and spread in equal parts
                  during the entire term of this Agreement.

         (e)      Incorporation by this Reference. The provisions of Section
                  3.1(d) shall be deemed to be incorporated into every document
                  or communication relating to the Obligations which sets forth
                  or prescribes any account, right or claim or alleged account,
                  right or claim of Lenders with respect to Borrower (or any
                  other obligor in respect of Obligations), whether or not any
                  provision of this Section 3.1 is referred to therein. All such
                  documents and communications and all figures set



                                       37


                  forth therein shall, for the sole purpose of computing the
                  extent of the Obligations and obligations of the Borrowers (or
                  other obligor) asserted by Agent or Lenders thereunder, be
                  automatically re-computed by any Borrower or obligor, and by
                  any court considering the same, to give effect to the
                  adjustments or credits required by Section 3.1(d).

         (f)      Unused Commitment Fee. Borrower agrees to pay to Agent for
                  distribution to Lenders a monthly unused commitment fee equal
                  to 0.375% per annum multiplied by the amount by which the
                  Total Commitment exceeds the Average Monthly Loan Balance;
                  provided, however, that if the Total Commitment exceeds the
                  Average Monthly Loan Balance by $50,000,000 or more at any
                  time during the first two (2) years following the Closing Date
                  the fee shall be increased to 0.50% per annum for such period.
                  Such unused commitment fee shall be payable (i) on the Closing
                  Date, and (ii) monthly in arrears on the first day of each
                  calendar month after the Closing Date.

         (g)      Closing Fees. Borrower shall pay to Agent on the Closing Date
                  for distribution to the Lenders a closing fee of $225,000 and
                  an underwriting fee to the Agent as provided in the letter
                  agreement between Borrower and Agent dated February ___, 2002.

         (h)      Agency Fee. Borrower shall pay to Agent on the Closing Date
                  and on each anniversary of the Closing Date during the term of
                  this Agreement an agency fee of Twenty Thousand Dollars
                  ($20,000).

         (i)      Capital Adequacy Charge. In the event that a Lender shall have
                  determined in good faith that the adoption of any law, rule or
                  regulation regarding capital adequacy, or any change therein
                  or in the interpretation or application thereof or compliance
                  by such Lender with any request or directive regarding capital
                  adequacy (whether or not having the force of law) from any
                  central bank or governmental authority, does or shall have the
                  effect of reducing the rate of return on such Lender's capital
                  as a consequence of its obligations hereunder to a level below
                  that which such Lender could have achieved but for such
                  adoption, change or compliance (taking into consideration such
                  Lender's policies with respect to capital adequacy) by an
                  amount deemed- by such Lender, in its sole discretion, to be
                  material, then from time to time, after submission by such
                  Lender to Borrower of a certificate certifying the amount by
                  which such rate of return is actually reduced with respect to
                  this transaction, together with the calculation and a written
                  demand therefor, Borrower shall promptly pay to such Lender
                  such additional amount or amounts as will compensate such
                  Lender for such reduction; provided, that, such Lender's other
                  debtors are required to reimburse such Lender for the same
                  type of reduction. The certificate of such Lender claiming
                  entitlement to payment as set forth above shall be conclusive
                  in the absence of manifest error. Such certificate shall set
                  forth the nature of the occurrence giving rise to such
                  payment, the additional amount or amounts to be paid to such
                  Lender, and the method by which such amounts were determined.
                  In determining such amount, a Lender may use any reasonable
                  averaging and attribution method, so



                                       38


                  long as it accurately reflects the reduction. A Lender
                  claiming amounts under this Section 3.1(i) agrees to provide
                  Borrower such additional information with respect thereto upon
                  request.

         (j)      Letter of Credit: LC Guaranty Fees. As additional
                  consideration for the Issuing Bank's issuing its Letters of
                  Credit for Borrower's account or for issuing its LC Guaranties
                  at Borrower's request pursuant to Section 2.4, Borrower agrees
                  to pay to the Issuing Bank, in addition to the Issuing Bank's
                  costs and expenses incurred in issuing such Letters of Credit
                  and LC Guaranties, fees equal to the Applicable Margin for
                  LIBOR Loans (equal to the face amount of each Letter of Credit
                  and LC Guaranty) times the face amount of each Letter of
                  Credit and LC Guaranty, which fee shall be deemed fully earned
                  upon issuance of each such Letter of Credit or LC Guaranty,
                  and shall be due and payable in equal monthly installments
                  beginning on the first Business Day of the month following the
                  date of issuance of such Letter of Credit or LC Guaranty and
                  continuing on the first Business Day of each month thereafter
                  during the term thereof. No fee payable by Borrower to the
                  Issuing Bank under this Section 3.1(j) shall be subject to
                  rebate or proration upon the termination of this Agreement for
                  any reason.

         Section 3.2 Additional Provisions Regarding LIBOR Loans.

         (a)      Borrower may select a LIBOR Rate with respect to all or any
                  portion of the Loans as provided in this Section 3.2;
                  provided, however, that (i) each LIBOR Loan shall be in a
                  principal amount of not less than One Million Dollars
                  ($1,000,000) (and, if greater than One Million Dollars
                  ($1,000,000), in integral multiples of One Hundred Thousand
                  Dollars ($100,000)), (ii) no more than five (5) LIBOR Periods
                  may be in existence at any one time, and (iii) Borrower may
                  not select a LIBOR Rate for a Loan if there exists a Default
                  or Event of Default. Borrower shall select LIBOR Periods with
                  respect to LIBOR Loans so that no LIBOR Period expires after
                  the end of the Original Term, or if extended pursuant to
                  Section 3.3, any Renewal Term. With respect to a LIBOR Loan,
                  the Borrowing Notice shall be delivered to Agent not later
                  than two (2) Business Days before the proposed borrowing date
                  referenced therein. An outstanding Base Rate Loan may be
                  converted to a LIBOR Loan at any time subject to the
                  provisions of this Section 3.2.

         (b)      Each LIBOR Loan shall bear interest from and including the
                  first day of the LIBOR Period applicable thereto (but not
                  including the last day of such LIBOR Period) at the interest
                  rate determined as applicable to such LIBOR Loan, but interest
                  on such LIBOR Loan shall be payable as provided in Section
                  3.6. If at the end of an LIBOR Period for an outstanding LIBOR
                  Loan, Borrower has failed to deliver to Lender a new Borrowing
                  Notice with respect to such LIBOR Loan or to pay such LIBOR
                  Loan, then such LIBOR Loan shall be converted to a Base Rate
                  Loan on and after the last day of such LIBOR Period and shall
                  remain a Base Rate Loan until paid or until the effective date
                  of a new Borrowing Notice with respect thereto.



                                       39


         (c)      If a Lender determines that maintenance of any of its portion
                  of LIBOR Loans would violate any applicable law, rule,
                  regulation or directive, whether or not having the force of
                  law, such Lender shall suspend the availability of its portion
                  of LIBOR Loans (the "Affected Portion") and require the
                  Affected Portion of any LIBOR Loans outstanding to be repaid;
                  or if such Lender determines that (i) deposits of a type or
                  maturity appropriate to match fund the Affected Portion of
                  LIBOR Loans are not available, or (ii) the LIBOR Rate does not
                  accurately reflect the cost of making the Affected Portion of
                  a LIBOR Loan, then such Lender shall promptly provide notice
                  to Borrower of its decision to suspend Borrower's ability to
                  make the Affected Portion of LIBOR Loans and/or require
                  Borrower to repay the Affected Portion of LIBOR Loans and
                  shall suspend the availability of the Affected Portion of
                  LIBOR Loans after the date of any such determination.

         (d)      If any payment of a LIBOR Loan occurs on a date which is not
                  the last day of the applicable LIBOR Period, whether because
                  of acceleration, prepayment or otherwise, or a LIBOR Loan is
                  not made on the date specified by Borrower because Borrower
                  has not satisfied the conditions precedent to such LIBOR Loan
                  contained in this Agreement or a Default or Event of Default
                  has occurred and is continuing, Borrower will indemnify
                  Lenders for any loss or cost incurred by it resulting
                  therefrom, including without limitation any loss or cost in
                  liquidating or employing deposits required to fund or maintain
                  the LIBOR Loan.

         (e)      Agent shall deliver a written statement as to the amount due,
                  if any, under Sections 3.2(c) or (d). Such written statement
                  shall set forth in reasonable detail the calculations upon
                  which Agent determined such amount and shall be final,
                  conclusive and binding on Borrower in the absence of manifest
                  error. Determination of amounts payable under such Sections in
                  connection with a LIBOR Loan shall be calculated as though the
                  affected Lender funded its portion of LIBOR Loan through the
                  purchase of a deposit of the type and maturity corresponding
                  to the deposit used as a reference in determining the LIBOR
                  Rate applicable to such Loan whether in fact that is the case
                  or not. Unless otherwise provided herein, the amount specified
                  in the written statement shall be payable on demand after
                  receipt by Borrower of the written statement.

         (f)      Borrower may prepay a LIBOR Loan only upon at least three (3)
                  Business Days prior written notice to Agent (which notice
                  shall be irrevocable). Borrower shall pay to Agent, upon
                  request of Agent, such amount or amounts as shall be
                  sufficient (in the reasonable opinion of Agent) to compensate
                  Lenders for any loss, cost, or expense incurred as a result
                  of: (i) any payment of a LIBOR Loan on a date other than the
                  last day of the LIBOR Period for such LIBOR Loan; (ii) any
                  failure by Borrower to borrow a LIBOR Loan on the date
                  specified by Borrower's written notice; or (iii) any failure
                  by Borrower to pay a LIBOR Loan on the date for payment
                  specified in Borrower's written notice. Without limiting the
                  foregoing, Borrower shall pay to Agent for the benefit of
                  Lenders a "yield maintenance fee" in an amount computed as
                  follows: the current rate for United States Treasury
                  securities (bills on a discounted basis shall be converted to
                  a bond equivalent) with a maturity date closest to the LIBOR
                  Period chosen pursuant to



                                       40


                  the LIBOR Loan as to which the prepayment is made, shall be
                  subtracted from the LIBOR Rate in effect at the time of
                  prepayment. If the result is zero or a negative number, there
                  shall be no yield maintenance fee. If the result is a positive
                  number, then the resulting percentage shall be multiplied by
                  the amount of the principal balance being prepaid. The
                  resulting amount shall be divided by 360 and multiplied by the
                  number of days remaining in the LIBOR Period chosen pursuant
                  to the LIBOR Loan as to which the prepayment is made. Said
                  amount shall be reduced to present value calculated by using
                  the above referenced United States Treasury securities rate
                  and the number of days remaining in the term chosen pursuant
                  to the LIBOR Loan as to which prepayment is made. The
                  resulting amount shall be the yield maintenance fee due to
                  Agent for the benefit of Lenders upon the prepayment of a
                  LIBOR Loan. If by reason of an Event of Default, Agent or the
                  Majority Lenders elect to declare the Obligations to be
                  immediately due and payable, then any yield maintenance fee
                  with respect to a LIBOR Loan shall become due and payable in
                  the same manner as though the Borrower had exercised such
                  right of prepayment.

         Section 3.3 Term of Agreement. Subject to the terms hereof and to
Lenders' right to cease making Loans to Borrower at any time upon or after the
occurrence of an Event of Default, this Agreement shall be in effect for (a) a
period of three (3) years from the date hereof, through and including February
___, 2005 (the "Term"). Upon written request by Borrower, Lenders may, in their
sole and absolute discretion, renew this Agreement for any number of successive
one year periods thereafter (each such successive one year period, a "Renewal
Term"), but Lenders shall have no obligation to do so. Notwithstanding anything
contained herein to the contrary, Lenders may terminate this Agreement without
notice upon or after the occurrence of an Event of Default.

         Section 3.4 Early Termination by Borrower. Borrower may terminate the
Revolving Credit Commitment hereunder at any time during the term of this
Agreement by repaying all outstanding Loans and the interest thereon, plus a
premium as follows: (i) if such prepayment occurs on or before the first
anniversary of the Closing Date, a premium of 2% of the then existing Revolving
Credit Commitment; (ii) if such prepayment occurs after the first anniversary of
the Closing Date and on or before the second anniversary of the Closing Date a
premium of 1.5% of the then existing Revolving Credit Commitment; and (iii) if
such prepayment occurs after the second anniversary of the Closing Date and on
or before the third anniversary of the Closing Date a premium of .5% of the then
existing Revolving Credit Commitment.

         Section 3.5 Effect of Termination. All of the Obligations shall be
forthwith due and payable upon any termination of this Agreement in accordance
with Section 3.4. Except as otherwise expressly provided for in this Agreement
or the other Loan Documents, no termination or cancellation (regardless of cause
or procedure) of this Agreement or any of the other Loan Documents shall in any
way affect or impair the rights, powers or privileges of Lenders or the
obligations, duties or liabilities of Borrower or Lenders in any way relating to
(a) any transaction or event occurring prior to such termination or cancellation
or (b) any of the undertakings, agreements, covenants, warranties or
representations of Borrower contained in this Agreement or any of the other Loan
Documents. All such undertakings, agreements, covenants, warranties and
representations of Borrower shall survive such termination or cancellation and
Agent shall retain



                                       41


its Liens in the Collateral and all of its rights and remedies under this
Agreement and the other Loan Documents notwithstanding such termination or
cancellation until all of the Obligations known existing, threatened or claimed
which can be given a monetary value have been paid in full, in immediately
available funds.

         Section 3.6 Payments.

         Principal and interest on the Loans shall be payable as follows:

         (a)      principal payable on account of Loans shall be payable by
                  Borrower to Lenders immediately upon the earliest of (i) the
                  receipt by Agent, a Lender or Borrower of any proceeds of any
                  of the Collateral, to the extent of said proceeds, (ii) the
                  occurrence of an Event of Default in consequence of which
                  Agent elects to accelerate the maturity and payment of such
                  Loans, or (iii) termination of this Agreement.

         (b)      interest accrued on the Loans shall be due on the earliest of
                  (i) the first day of each month (for the immediately preceding
                  month), computed through the last calendar day of the
                  preceding month, (ii) the occurrence of an Event of Default in
                  consequence of which Agent elects to accelerate the maturity
                  and payment of the Obligations, or (iii) termination of this
                  Agreement.

         (c)      reasonable and itemized costs, fees and expenses payable
                  pursuant to this Agreement shall be promptly payable by
                  Borrower to Agent or to any other Person designated by Agent
                  in writing.

         (d)      the balance of the Obligations requiring the payment of money,
                  if any, shall be payable by Borrower to Agent as and when
                  provided in this Agreement, the Other Agreements or the
                  Security Documents, or, if not otherwise provided, then on
                  demand.

         Borrower hereby irrevocably authorizes Agent, in Agent's good faith
discretion, to advance to Borrower and to charge to the Loan Account as a
Revolving Loan, sums sufficient to pay all amounts due and payable under
Sections 3.6(b), (c) and (d) above whether or not any such advance would cause
the outstanding Revolving Loans to exceed the Borrowing Base.

         Section 3.7 Application of Payments and Collections. (a) Except as
otherwise provided in this Section 3.7, Borrower irrevocably waives the right to
direct the application of any and all payments and collections at any time or
times hereafter received by Agent or Lenders from or on behalf of Borrower, and
Borrower does hereby irrevocably agree that Agent shall have the continuing
exclusive right to apply and reapply any and all such payments and collections
received at any time or times hereafter by Agent or its agent against the
Obligations, in such manner as Agent may deem advisable, notwithstanding any
entry by Agent upon any of its books and records. If as the result of
collections of Accounts as authorized by Section 5.2 a credit balance exists in
the Loan Account with respect to the Revolving Credit Commitment, such credit
balance shall not accrue interest in favor of Borrower, but shall be returned to
Borrower within one (1) Business Day for so long as no Default or Event of
Default exists.



                                       42


Agent may offset any credit balance against the Obligations upon or after the
occurrence of an Event of Default. Payments and collections received by Agent
from the Dominion Account or otherwise in Houston, Texas (a) before 2:00 p.m.
Central Standard Time on a Business Day shall be deemed received on such
Business Day, and (b) after 2:00 p.m. Central Standard Time on a Business Day
shall be deemed received on the next succeeding Business Day, in each case for
purposes of determining the amount of Revolving Loans available for borrowing
hereunder and for purposes of computing interest on the Loans (subject in each
case to final payment of all items and collections received in form other than
immediately available funds). For so long as no Event of Default has occurred,
all payments and collections deposited into the Dominion Account shall be
transferred to a bank account specified by Borrower, and upon the occurrence of
an Event of Default, Agent may, in its sole discretion, direct all such payments
and collections to be transferred to a bank account specified by Agent.

         (a)      All monies to be applied to the Obligations, other than as
                  expressly provided for elsewhere in this Agreement, whether
                  such monies represent voluntary payments by the Borrower or
                  are received pursuant to demand for payment or realized from
                  any disposition of Collateral, shall be allocated among the
                  Agent and such of the Lenders and other holders of the
                  Obligations as are entitled thereto (and, with respect to
                  monies allocated to the Lenders, on a ratable basis unless
                  otherwise provided in this Section 3.7): (i) to pay principal
                  and accrued interest on any Overadvance; (ii) second, to the
                  Agent to pay the amount of expenses that have not been
                  reimbursed to the Agent by the Borrower or the Lenders,
                  together with interest accrued thereon; (iii) third, to the
                  Agent to pay any indemnified amount that has not been paid to
                  the Agent by the Borrower or the Lenders, together with
                  interest accrued thereon; (iv) fourth, to the Agent to pay any
                  fees due and payable to the Agent under this Agreement; (v)
                  fifth, to the Lenders for any indemnified amount that they
                  have paid to the Agent and for any expenses that they have
                  reimbursed to the Agent; (vi) sixth, to the Lenders to pay any
                  fees due and payable to the Lenders under this Agreement;
                  (vii) seventh, in payment of the unpaid principal and accrued
                  interest in respect of the Loans and (viii) eighth, any other
                  Obligations then outstanding and held by any Lender to be
                  shared among the Lenders on a ratable basis, or on such other
                  basis as may be agreed upon in writing by all of the Lenders
                  (which agreement or agreements may be entered into without
                  notice to or the consent or approval of the Borrower). The
                  allocations set forth in this Section 3.7 are solely to
                  determine the rights and priorities of the Agent and the
                  Lenders as among themselves and may be changed by the Agent
                  and the Lenders without notice to or the consent or approval
                  of the Borrower or any other Person.

         Section 3.8 Statements of Account. Agent will account to Borrower
monthly with a statement of Loans, charges and payments made pursuant to this
Agreement, and such account rendered by Agent, absent manifest error, shall be
deemed final, binding and conclusive upon Borrower unless Agent is notified by
Borrower in writing to the contrary within seventy-five (75) days after the date
each account is mailed to Borrower. Such notice shall only be deemed an
objection to those items specifically objected to therein.



                                       43


         Section 3.9 Increased Costs. If any law or any governmental or
quasi-governmental rule, regulation, policy, guideline or directive (whether or
not having the force of law) adopted after the date of this Agreement and having
general applicability to all banks within the jurisdiction in which any Lender
operates (excluding, for the avoidance of doubt, the effect of and phasing in of
capital requirements or other regulations or guidelines passed prior to the date
of this Agreement), or any interpretation or application thereof by any
governmental authority charged with the interpretation or application thereof,
or the compliance of any Lender therewith, shall:

         (a)      (i) subject any Lender to any tax with respect to this
                  Agreement (other than (A) any tax based on or measured by net
                  income or otherwise in the nature of a net income tax,
                  including, without limitation, any franchise tax or any
                  similar tax based on capital, net worth or comparable basis
                  for measurement and (B) any tax collected by a withholding on
                  payments and which neither is computed by reference to the net
                  income of the payee nor is in the nature of an advance
                  collection of a tax based on or measured by the net income of
                  the payee) or (ii) change the basis of taxation of payments to
                  any Lender of principal, fees, interest or any other amount
                  payable hereunder or under any Loan Documents (other than in
                  respect of (A) any tax based on or measured by net income or
                  otherwise in the nature of a net income tax, including,
                  without limitation, any franchise tax or any similar tax based
                  on capital, net worth or comparable basis for measurement and
                  (B) any tax collected by a withholding on payments and which
                  neither is computed by reference to the net income of the
                  payee nor is in the nature of an advance collection of a tax
                  based on or measured by the net income of the payee);

         (b)      impose, modify or hold applicable any reserve (except any
                  reserve taken into account in the determination of the
                  applicable LIBOR Rate), special deposit, assessment or similar
                  requirement against assets held by, or deposits in or for the
                  account of, advances or loans by, or other credit extended by,
                  any office of any Lender, including (without limitation)
                  pursuant to Regulation D of the Board of Governors of the
                  Federal Reserve System; or

         (c)      impose on any Lender or the London interbank market any other
                  condition with respect to any Loan Document;

and the result of any of the foregoing is to increase the cost to any Lender of
making, renewing or maintaining Loans hereunder by an amount that any Lender
deems to be material or to reduce the amount of any payment (whether of
principal, interest or otherwise) in respect of any of the Loans by an amount
that any Lender deems to be material, then, in any such case, Borrower shall pay
such Lender, upon demand and certification not later than sixty (60) days
following its receipt of notice of the imposition of such increased costs, such
additional amount as will compensate such Lender for such additional cost or
such reduction, as the case may be, to the extent such Lender has not otherwise
been compensated, with respect to a particular Loan, for such increased cost as
a result of an increase in the Base Rate or the LIBOR Rate. An officer of such
Lender shall determine the amount of such additional cost or reduced amount
using reasonable averaging and attribution methods and shall certify the amount
of such additional cost or reduced amount to Borrower, which certification shall
include a written explanation of such



                                       44


additional cost or reduction to Borrower and a statement that such costs affect
other borrowers with similar LIBOR loans. Such certification shall be conclusive
absent manifest error. If such Lender claims any additional cost or reduced
amount pursuant to this Section 3.8, then such Lender shall use reasonable
efforts (consistent with legal and regulatory restrictions) to designate a
different lending office or to file any certificate or document reasonably
requested by Borrower if the making of such designation or filing would avoid
the need for, or reduce the amount of, any such additional cost or reduced
amount and would not, in the sole discretion of such Lender, be otherwise
disadvantageous to such Lender.

         Section 3.10 Basis for Determining Interest Rate Inadequate or Unfair.
In the event that Agent shall have determined that:

         (a)      reasonable means do not exist for ascertaining the LIBOR Rate
                  for any LIBOR Period; or

         (b)      Dollar deposits in the relevant amount and for the relevant
                  maturity are not available in the London interbank market with
                  respect to a proposed LIBOR Loan, or a proposed conversion of
                  a Base Rate Loan into a LIBOR Loan; then

Agent shall give Borrower prompt written, telephonic or electronic notice of the
determination of such effect. If such notice is given, (i) any such requested
LIBOR Loan shall be made as a Base Rate Loan, unless Borrower shall notify Agent
no later than 10:00 A.M. (Dallas, Texas Time) two (2) Business Days prior to the
date of such proposed borrowing that the request for such borrowing shall be
canceled or made as an unaffected type of LIBOR Loan, and (ii) any Base Rate
Loan which was to have been converted to an affected type of LIBOR Loan shall be
continued as or converted into a Base Rate Loan, or, if Borrower shall notify
Agent, no later than 10:00 A.M. (Dallas, Texas Time) two (2) Business Days prior
to the proposed conversion, shall be maintained as an unaffected type of LIBOR
Loan.

                                       46


therein, Agent will not enforce its security interest in Borrower's rights under
such lease or license (other than in respect of the Proceeds thereof) for so
long as such prohibition continues, it being understood that upon request of
Agent, Borrower will in good faith use reasonable efforts to obtain consent for
the creation of a security interest in favor of Agent (and to Agent's
enforcement of such security interest) in such Agent's rights under such lease
or license.

         Section 4.2 Other Collateral.

         (a)      Commercial Tort Claims. Borrower shall promptly notify Agent
                  in writing upon incurring or otherwise obtaining a Commercial
                  Tort Claim after the Closing Date against any third party and,
                  upon request of Agent, promptly enter into an amendment to
                  this Agreement and do such other acts or things deemed
                  appropriate by Agent to give Agent a security interest in any
                  such Commercial Tort Claim.

         (b)      Other Collateral. Borrower shall promptly notify Agent in
                  writing upon acquiring or otherwise obtaining any Collateral
                  after the date hereof consisting of Deposit Accounts,
                  Investment Property, Letter-of-Credit Rights or Electronic
                  Chattel Paper and, upon the request of Agent, promptly execute
                  such other documents, and do such other acts or things deemed
                  appropriate by Agent to deliver to Agent control with respect
                  to such Collateral; promptly notify Agent in writing upon
                  acquiring or otherwise obtaining any Collateral after the date
                  hereof consisting of Documents or Instruments and, upon the
                  request of Agent, will promptly execute such other documents,
                  and do such other acts or things deemed appropriate by Agent
                  to deliver to Agent possession of such Documents which are
                  negotiable and Instruments, and, with respect to nonnegotiable
                  Documents, to have such nonnegotiable Documents issued in the
                  name of Agent; and with respect to Collateral in the
                  possession of a third party, other than Certificated
                  Securities and Goods covered by a Document and obtain an
                  acknowledgement from the third party that it is holding the
                  Collateral for the benefit of Agent.

         The security interests in the Collateral granted to Agent by Borrower
are given in renewal, extension and modification of the security interests
previously granted to Fleet by Cal Dive and ERT in the Amended Loan Documents;
such prior security interests are not extinguished hereby; and the making,
perfection and priority of such prior security interests shall continue in full
force and effect.

         Section 4.3 Lien on Vessels. (a) The due and punctual payment and
performance of the Obligations shall be secured by the Lien created by the Ship
Mortgages upon the Vessels. Except as otherwise permitted herein, if Borrower
shall acquire at any time or times hereafter any interest in other vessels,
Borrower hereby agrees to promptly execute and deliver to Agent, as additional
security and Collateral for the Obligations, Ship Mortgages or other collateral
documents satisfactory in form and substance to Agent and its counsel (herein
collectively referred to as "New Ship Mortgages") covering such new vessels. The
Ship Mortgages and each New Ship Mortgage shall be duly recorded in each office
where such recording is required to constitute a valid and perfected Lien on the
vessels covered by such Mortgage. Borrower shall



                                       47


deliver to Agent such other documents as Agent and its counsel may reasonably
request relating to the Property subject to the Ship Mortgage and any New Ship
Mortgages.

         (b)      Upon demand by Agent, Borrower shall execute and deliver to
                  Agent the Construction Contract Assignment and shall do all
                  such other things deemed appropriate by Agent to perfect such
                  assignment as a first preferred security interest on the
                  collateral described in it.


         Section 4.4 Negative Pledge. Borrower agrees that for so long as any
Obligations remain outstanding, it will not, without the prior written consent
of Agent create or permit any Lien (other than Permitted Liens) or its interests
in the Offshore Platforms and its other oil and gas Properties.

         Section 4.5 Representations, Warranties and Covenants. To induce
Lenders to enter into this Agreement, Borrower represents, warrants, and
covenants to Agent and Lender:

         (a)      The Collateral is now and, so long as any of the Obligations
                  are outstanding, will continue to be owned solely by Borrower,
                  and no other Person has or will have any right, title,
                  interest, claim, or Lien therein, thereon or thereto other
                  than a Permitted Lien.

         (b)      Except for Permitted Liens or as specifically consented to in
                  writing by Agent the Liens granted to Agent shall be first and
                  prior on the Collateral and as to the Accounts and proceeds,
                  including insurance proceeds, resulting from the sale,
                  disposition, or loss thereof. No further action need be taken
                  to perfect the Liens granted to Lender, other than the filing
                  of continuation statements under the Code or other applicable
                  law, continued possession by Agent of that portion of the
                  Collateral constituting instruments or documents, the
                  recording of the Ship Mortgage and each New Ship Mortgage as
                  required by applicable law.

         (c)      All goods evidenced by the Collateral constituting chattel
                  paper, documents or instruments, the possession of which has
                  been given to Agent, are owned by Borrower and the same are
                  free and clear of any prior Lien, except for Statutory Liens
                  contested by Borrower as required by Section 8.2(h). Borrower
                  further warrants and guarantees the value, quantities,
                  adequate condition, grades and qualities of the goods and
                  services described therein. Borrower shall pay and discharge
                  when due all taxes, levies, and other charges upon said
                  Collateral and upon the goods evidenced by any documents
                  constituting Collateral, except and to the extent only that
                  such taxes, levies and other charges are being actively
                  contested in good faith and by appropriate lawful proceedings,
                  and Borrower has established adequate reserves therefor, which
                  are properly reflected on the Consolidated Financial
                  Statements, and the nonpayment of such taxes, levies and
                  charges does not result in a lien upon any Collateral other
                  than a Permitted Lien. Borrower shall defend Agent against and
                  save it harmless from all claims of any Person with respect to
                  the Collateral. This indemnity shall include reasonable
                  attorneys' fees and legal expenses.



                                       48


         Section 4.6 Lien Perfection. Borrower agrees to execute the UCC-1
financing statements provided for by the Code or otherwise together with any and
all other instruments, assignments or documents and shall take such other action
as may be required to perfect or to continue the perfection of Agent's security
interest in the Collateral. Unless prohibited by applicable law, Borrower hereby
authorizes Agent to execute and file any such financing statement on Borrower's
behalf, including without limitation financing statements that indicate the
Collateral (i) as all assets of Cal Dive, ERT, Aquatica or Canyon or words of
similar effect, or (ii) as being equal or lesser in scope or with greater or
lesser detail, than as set forth in Section 4.1 on Borrower's behalf. Borrower
also hereby ratifies its authorization for the Agent to have filed in any
jurisdiction any like financial statements or amendments thereto if filed prior
to the date hereof. The parties agree that a carbon, photographic or other
reproduction of this Agreement shall be sufficient as a financing statement and
may be filed in any appropriate office in lieu thereof.

         Section 4.7 Location of Collateral. All Collateral, other than
Inventory in transit, motor vehicles, Vessels and diving equipment, will at all
times be kept by Borrower at one or more of the business locations set forth in
Exhibit C attached hereto and shall not, without the prior written approval of
Agent, be moved therefrom except, prior to an Event of Default, for (a) sales of
Inventory and the providing of services in the ordinary course of business; (b)
the storage of Inventory at locations within the continental United States other
than those shown on Exhibit C attached hereto if (i) Borrower gives Agent
written notice of the new storage location at least sixty (60) days prior to
storing Inventory at such location, (ii) except for Statutory Liens contested by
Borrower as required by Section 8.2(h), Agent's security interest in such
Inventory is and continues to be a duly perfected, first priority Lien thereon,
(iii) neither Borrower's nor Agent's right of entry upon the premises where such
Inventory is stored, or its right to remove the Inventory therefrom, is in any
way restricted, (iv) the owner of such premises agrees with Agent not to assert
any landlord's, bailee's or other Lien in respect of the Inventory for unpaid
rent or storage charges, and (v) all negotiable documents and receipts in
respect of any Collateral maintained at such premises are promptly delivered to
Agent; (c) temporary transfers (for period not to exceed three months in any
event) of Equipment from a location set forth on Exhibit C attached hereto to
another location if done for the limited purpose of repairing, refurbishing or
overhauling such Equipment in the ordinary course of Borrower's business; and
(d) removals in connection with dispositions of Equipment that are authorized by
Section 6.4.

         Section 4.8 Insurance of Collateral. Borrower agrees to maintain and
pay for insurance upon all Collateral (other than Offshore Platforms) wherever
located, in storage or in transit, including goods evidenced by documents,
covering casualty, hazard, public liability and such other risks and in such
amounts and with insurance companies acceptable to Agent. Borrower shall deliver
to Agent certificates regarding such insurance and the originals of such
policies when available, with satisfactory endorsements naming Agent as loss
payee or co-insured and as mortgagee pursuant to a standard mortgagee clause
without liability for premiums, club calls or assessments. Each policy of
insurance or endorsement shall contain a clause requiring the insurer to give
not less than thirty (30) days prior written notice to Agent in the event of
cancellation of the policy for any reason whatsoever and a clause that the
interest of Agent shall not be impaired or invalidated by any act or neglect of
Borrower or owner of the Property nor by the occupation of the premises for
purposes more hazardous than are permitted by said policy. If Borrower fails to
provide and pay for such insurance, Agent may, at



                                       49


Borrower's expense, procure the same, but shall not be required to do so.
Borrower agrees to deliver to Agent, promptly as rendered, true copies of all
reports made in any reporting forms to insurance companies. Borrower will
maintain, with financially sound and reputable insurers, insurance with respect
to its Properties and business against such casualties and contingencies of such
type (including public liability, product liability, larceny, embezzlement, or
other criminal misappropriation insurance) and in such amounts as is customary
in the business or as otherwise required by Agent.

         Section 4.9 Protection of Collateral. All insurance expenses and all
expenses of protecting, storing, warehousing, insuring, handling, maintaining
and shipping the Collateral, any and all excise, property, sales, and use taxes
imposed by any state, federal, or local authority on any of the Collateral or in
respect of the sale thereof shall be bome and paid by Borrower. If Borrower
fails to promptly pay any portion thereof when due or is not actively contesting
such taxes in good faith and by appropriate proceedings and has not established
adequate reserves, which are properly reflected on the Consolidated Financial
Statements, Agent may, at its option, but shall not be required to, pay the same
and charge the Loan Account therefor. Borrower agrees to reimburse Agent
promptly therefor with interest accruing thereon daily at the Applicable Annual
Rate for Base Rate Loans. All sums so paid or incurred by Agent for any of the
foregoing and all costs and expenses (including reasonable attorneys' fees,
legal expenses, and court costs) which Agent may incur in enforcing or
protecting its Lien on or rights and interest in the Collateral or any of its
rights or remedies under any Loan Document or in respect of any of the
transactions to be had hereunto, together with interest at the Default Rate
applicable to Base Rate Loans, shall be considered Obligations hereunder secured
by all Collateral. Agent shall not be liable or responsible in any way for the
safekeeping of any of the Collateral or for any loss or damage thereto (except
for reasonable care in the custody thereof while any Collateral is in Agent's
actual possession) or for any diminution in the value thereof, or for any act or
default of any warehouseman, carrier, forwarding agency, or other person
whomsoever, but the same shall be at Borrower's sole risk.

                   ARTICLE 5. PROVISIONS RELATING TO ACCOUNTS

         Section 5.1 Representations, Warranties and Covenants. With respect to
all Accounts, Borrower represents and warrants to Agent and Lenders that Agent
may rely, in determining which Accounts are Eligible Accounts, on all statements
and representations made by Borrower with respect to any Account or Accounts,
and, unless otherwise indicated in writing to Agent, that with respect to each
Account:

         (a)      it is genuine and in all respects what it purports to be, and
                  it is not evidenced by a judgment;

         (b)      it arises out of a completed, bona fide sale and delivery of
                  goods or rendition of services by Borrower in the ordinary
                  course of its business and in accordance with the terms and
                  conditions of all purchase orders, contracts or other
                  documents relating thereto and forming a part of the contract
                  between Borrower and the Account Debtor;



                                       50


         (c)      it has been generated in compliance with Borrower's normal
                  credit policies as historically in effect (or as modified from
                  time to time on prior written notice to Agent) or on such
                  other reasonable terms disclosed in writing to Agent in
                  advance of the creation of such Account, and such terms are
                  expressly set forth on the face of the invoice covering such
                  sale or rendition of services;

         (d)      it is for a liquidated amount maturing as stated in the
                  duplicate invoice covering such sale or rendition of services,
                  a copy of which has been furnished or is available to Agent;

         (e)      Borrower has made no agreement with any Account Debtor
                  thereunder for any deduction therefrom, except discounts or
                  allowances which are granted by Borrower in the ordinary
                  course of its business and which are disclosed to Agent;

         (f)      to the best of Borrower's knowledge, there are no facts,
                  events or occurrences which have not been disclosed to Agent
                  which in any way impair the validity or enforceability thereof
                  or tend to reduce the amount payable thereunder from the face
                  amount of the invoice and statements delivered to Agent with
                  respect thereto;

         (g)      to the best of Borrower's knowledge, the Account Debtor
                  thereunder (i) is Solvent and (ii) had the capacity to
                  contract at the time any contract or other document giving
                  rise to the Account was executed; and

         (h)      Borrower has no knowledge of any fact or circumstance which
                  would impair the validity or collectability of the Account,
                  and to the best of Borrower's knowledge there are no
                  proceedings or actions which are threatened or pending against
                  any Account Debtor thereunder which might result in any
                  material adverse change in such Account Debtor's financial
                  condition or the collectability of such Account.

         Section 5.2 Assignments, Records and Schedules of Accounts. If so
requested by Agent, Borrower shall execute and deliver to Agent formal written
assignments of all of its Accounts on a weekly or more frequent basis, which
shall include all Accounts that have been created since the date of the last
assignment, together with copies of invoices or invoice registers related
thereto. Borrower shall keep accurate and complete records of its Accounts and
all payments and collections thereon and shall submit to Agent on a weekly
basis, unless requested on a more frequent basis by Agent, a sales and
collections report for the preceding week, in form satisfactory to Agent. On or
before the last day of each week from and after the date hereof, Borrower shall
deliver to Agent, in form satisfactory to Agent, a detailed listing of all
Unbilled Accounts existing as of the last day of the preceding week, a detailed
aged trial balance of all Accounts existing as of the last day of the preceding
week, specifying the names, face value, dates of invoices and due dates for each
Account Debtor obligated on an Account so listed and a listing of all disputed
amounts due and owing (a "Schedule of Accounts"), and upon Agent's request
therefor, the reason for any disputed amounts, all claims related thereto and
the amount in controversy, and addresses, copies of proof of delivery and the
original copy of all documents, including, without limitation, repayment
histories and present status reports relating to the Accounts so scheduled, and
such other matters and information relating to the status of then existing
Accounts as Agent shall reasonably request.



                                       51


         Section 5.3 Administration of Accounts.

         (a)      Borrower shall report discounts, allowances or credits granted
                  by Borrower that are not shown on the face of the invoice for
                  the Account involved to Agent at the time of its submission to
                  Agent of the next Schedule of Accounts as provided in Section
                  5.2 or more frequently upon the request of Agent. Upon and
                  after the occurrence of an Event of Default, Agent shall have
                  the right to settle or adjust all disputes and claims directly
                  with the Account Debtor and to compromise the amount or extend
                  the time for payment of the Accounts upon such terms and
                  conditions as Agent may deem advisable, and to charge the
                  deficiencies, costs and expenses thereof, including reasonable
                  attorney's fees, to Borrower.

         (b)      If an Account includes a charge for any tax payable to any
                  governmental taxing authority, Agent is authorized, in its
                  sole discretion, to pay the amount thereof to the proper
                  taxing authority for the account of Borrower and to charge the
                  Loan Account therefor. Borrower shall notify Agent if any
                  Account includes any tax due to any govenunental taxing
                  authority and, in the absence of such notice, Agent shall have
                  the right to retain the full proceeds of the Account and shall
                  not be liable for any taxes to any governmental taxing
                  authority that may be due by Borrower by reason of the sale
                  and delivery creating the Account.

         (c)      Whether or not an Event of Default has occurred, any of
                  Agent's officers, employees or agents shall have the right, at
                  any time or times hereafter, in the name of Agent, any
                  designee of Agent or Borrower, to verify the validity, amount
                  or any other matter relating to any Accounts by mail,
                  telephone, telegraph or otherwise. Borrower shall cooperate
                  fully with Agent in an effort to facilitate and promptly
                  conclude any such verification process.

         Section 5.4 Collection of Accounts.

         (a)      To expedite collection, Borrower shall endeavor in the first
                  instance to make collection of its Accounts for Agent. All
                  remittances received by Borrower on account of Accounts shall
                  be held as Agent's property by Borrower as trustee of an
                  express trust for Agent's benefit and Borrower shall
                  immediately deposit same in the Dominion Account. Agent shall
                  have the right at any time after the occurrence of an Event of
                  Default to notify Account Debtors that Accounts have been
                  assigned to Agent and to collect Accounts directly in its own
                  name and to charge the collection costs and expenses,
                  including reasonable attorneys' fees, to Borrower. Agent has
                  no duty to protect, insure, collect or realize upon the
                  Accounts or preserve rights in them.

         (b)      Borrower shall deposit all proceeds of the Collateral, other
                  than receipts for the sale of Property held by third parties
                  as reserves for like/kind exchanges, or cause the same to be
                  deposited in kind in a Dominion Account pursuant to a lockbox
                  arrangement with such banks as may be selected by Borrower and
                  be acceptable to Agent. Borrower shall issue to any such bank,
                  an irrevocable letter of instruction directing such banks to
                  deposit all payments or other remittances



                                       52


                  received in the lockbox to the Dominion Account for
                  application on account of the Obligations. All funds deposited
                  in the Dominion Account shall immediately become the property
                  of Agent and Borrower shall obtain the agreement by such banks
                  to waive any offset rights against the funds so deposited.
                  Agent assumes no responsibility for such lockbox arrangement,
                  including, without limitation, any claim of accord and
                  satisfaction or release with respect to deposits accepted by
                  any bank thereunder.

                  value and operating efficiency of the Equipment and the
                  Vessels shall be maintained and preserved, reasonable wear and
                  tear excepted; and

         (b)      except for Equipment affixed to Offshore Platforms in the
                  ordinary course of ERT's business, Borrower will not permit
                  any of the Equipment to become affixed to any Real Property
                  leased to Borrower so that an interest arises therein under
                  the real estate laws of the applicable jurisdiction unless the
                  landlord of such Real Property has executed a landlord waiver
                  or leasehold mortgage in favor of Agent, and Borrower will not
                  permit any of the Equipment to become an accession to any
                  personal Property other than Equipment subject to first
                  priority Liens in favor of Agent or subject to Permitted
                  Liens.

foregoing information on at least an annual basis and more often if requested by
Agent.

         Section 6.4 Dispositions. Borrower will not sell, lease or otherwise
dispose of or transfer any of the Equipment, any Vessel, any Offshore Platform,
or any oil or gas Properties, or any part thereof without the prior written
consent of Agent; provided, however, that the foregoing restriction shall not
apply to dispositions required by the United States government, or, for so long
as no Event of Default exists, to the following:

                  and not mortgaged to Agent in the ordinary course of business;
                  provided, that, all proceeds thereof, other than receipts for
                  the sale of Property held by third parties as reserves for
                  like/kind exchanges, are delivered to Agent for application to

                  Agreement; or

         (b)      replacement of Equipment and Vessels that are substantially
                  worn, damaged or obsolete with Equipment or Vessels of
                  substantially like kind and function and with a value not less
                  than the Equipment or Vessels being replaced; which
                  replacement Equipment and Vessels shall be acceptable to
                  Agent; provided, that, (i) the replacement Equipment or
                  Vessels shall be acquired prior to concurrently with or within
                  six (6) months of any disposition of the Equipment or Vessel
                  that is to be replaced, (ii) the replacement Equipment or

                  against dispositions of Equipment, Vessels or Offshore
                  Platforms set forth in this Section 6.4 shall be construed to
                  allow any disposition, whether by Borrower of a Vessel on
                  which Agent has been granted a Lien, without the prior written
                  consent of Agent.

                   ARTICLE 7. REPRESENTATIONS AND WARRANTIES

         Section 7.1 General Representations and Warranties. To induce Lenders
to enter into this Agreement and to make advances hereunder, Borrower warrants,
represents and covenants to Agent and Lenders as follows:

         (a)      Organization and Qualification. Borrower is a corporation duly
                  organized, validly existing and in good standing under the
                  laws of the state of its incorporation. Borrower has duly
                  qualified and is authorized to do business and is in good

                  part hereof and in all other states and jurisdictions where
                  the character of its Properties or the nature of its
                  activities make such qualification necessary.

         (b)      Corporate Names. Since July 27, 1990, Cal Dive, since
                  September 30, 1992, ERT since September 24, 1997, Aquatica and

                  Except as set forth on Exhibit E attached hereto, Borrower has
                  not, during the preceding three years, been the surviving
                  corporation of a merger or consolidation or acquired all or
                  substantially all of the assets of any Person. Each Borrower's
                  exact legal name, state of incorporation, type of organization
                  and organizational identification number is set forth on
                  Exhibit E.



                                       54


         (c)      Corporate Power and Authority. Borrower has the right and
                  power and is duly authorized and empowered to enter into,
                  execute, deliver and perform this Agreement and each of the
                  other Loan Documents to which it is a party. The execution,
                  delivery and performance of this Agreement and each of the
                  other Loan Documents have been duly authorized by all
                  necessary corporate action and do not and will not (i) require
                  any consent or approval of the shareholders of Borrower; (ii)
                  contravene Borrower's charter, articles of incorporation or
                  by-laws; (iii) violate, or cause Borrower to be in default
                  under, any provision of any law, rule, regulation, order,

                  effect having applicability to Borrower; (iv) result in a
                  breach of or constitute a default under any indenture or loan
                  or credit agreement or any other agreement, lease or
                  instrument to which Borrower is a party or by which it or its
                  Properties may be bound or affected; or (v) result in, or
                  require, the creation or imposition of any Lien (other than
                  Permitted Liens) upon or with respect to any of the Properties
                  now owned or hereafter acquired by Borrower.

         (d)      Legally Enforceable Agreement. This Agreement is, and each of
                  the other Loan Documents when delivered under this Agreement
                  will be, a legal, valid and binding obligation of Borrower
                  enforceable against it in accordance with their respective
                  terms, except to the extent that such enforcement may be
                  limited by applicable bankruptcy, insolvency and other similar
                  laws affecting creditors' rights generally or by principles of
                  equity pertaining to the availability of equitable remedies.

         (e)      Use of Proceeds. Borrower's uses of the proceeds of any Loans
                  pursuant to this Agreement are, and will continue to be, legal
                  and proper corporate uses, duly authorized by its Board of
                  Directors, and such uses will not violate any applicable laws,
                  including, without limitation, the Foreign Assets Control
                  Regulations, the Foreign Funds Control Regulations and the
                  Transaction Control Regulations of the United States Treasury
                  Department (31 CFR, Subtitle B, Chapter V, as amended), where
                  the failure to do so would have a material adverse effect on
                  its business, condition (financial or otherwise), operations,
                  prospects, or Properties.

         (f)      Margin Stock. Borrower is not engaged principally, or as one
                  of its important activities, in the business of purchasing or
                  carrying "margin stock" (within the meaning of Regulation U of
                  the Board of Governors of the Federal Reserve System), and no
                  part of the proceeds of any Loans to Borrower will be used to
                  purchase or carry any margin stock or to extend credit to
                  others for the purpose of purchasing or carrying any margin
                  stock or be used for any purpose which violates or is
                  inconsistent with the provisions of Regulation T, U or X of
                  said Board of Governors.

         (g)      Governmental Consents. Except where failure to do so would
                  have a material adverse effect on its business, condition
                  (financial or otherwise), operations, prospects, or
                  Properties, Borrower has, and is in good standing with respect
                  to, all governmental consents, approvals, authorizations,
                  permits, certificates, inspections, and franchises necessary
                  to continue to conduct its business as



                                       55


                  heretofore or proposed to be conducted by it and to own or
                  lease and operate its Properties as now owned or leased by it.

         (h)      Patents, Trademarks, Copyrights and Licenses. Borrower owns or
                  possesses all the patents, trademarks, service marks, trade
                  names, copyrights and licenses necessary for the present and
                  planned future conduct of its business without any known
                  conflict with the rights of others. All such patents,
                  trademarks, service marks, trade names, copyrights, licenses
                  and other similar rights are listed on Exhibit F attached
                  hereto and made a part hereof.

         (i)      Capital Structure. Exhibit G attached hereto and made a part
                  hereof states (i) the correct name of each of the Subsidiaries
                  of Borrower, the jurisdiction of incorporation and the
                  percentage of its Voting Stock owned by Borrower, (ii) the
                  name of each of Borrower's corporate or joint venture
                  Affiliates and the nature of the affiliation, (iii) the
                  number, nature and holder of all outstanding Securities of
                  each Subsidiary of Cal Dive, and (iv) the number of
                  authorized, issued and treasury shares of Borrower and each

                  shares of stock it purports to own of each Subsidiary, free
                  and clear in each case of any Lien other than Permitted Liens.
                  All such shares have been duly issued and are fully paid and
                  nonassessable. Except as provided in Exhibits G and H attached
                  hereto, there are not outstanding any options to purchase, or
                  any rights or warrants to subscribe for, or any commitments or
                  agreements to issue or sell, or any Securities or obligations
                  convertible into, or any powers of attorney relating to,
                  shares of the capital stock of Borrower.

         Except as provided in Exhibits G and H attached hereto, there are not
outstanding any agreements or instruments binding upon any of Borrower's
shareholders relating to the ownership of its shares of capital stock.

         Section 7.2 Solvent Financial Conditions. Borrower is now and, after
giving effect to initial Loans to be made hereunder, at all times will be,
Solvent.


         (a)      Restrictions. Borrower is not a party or subject to any
                  contract, agreement, or charter or other ------------
                  corporate restriction, which materially and adversely affects
                  its business or the use or ownership of any of its Properties
                  other than as set forth on Exhibit I attached hereto. Borrower
                  is not a party or subject to any contract or agreement which
                  restricts its right or ability to incur Indebtedness, other
                  than as set forth on Exhibit I attached hereto, none of which
                  prohibit the execution of or compliance with this Agreement by
                  Borrower. Neither Borrower nor any of its Subsidiaries has
                  agreed or consented to cause or permit in the future (upon the
                  happening of a contingency or otherwise) any of its Property,
                  whether now owned or hereafter acquired, to be subject to a
                  Lien that is not a Permitted Lien.

         (b)      Litigation. Except as set forth on Exhibit J attached hereto
                  and made a part hereof, there are no actions, suits,
                  proceedings or investigations pending, or to the knowledge of
                  Borrower, threatened, against or affecting Borrower or any of
                  its Subsidiaries, or the business, operations, Properties,
                  prospects, profits or



                                       56


                  condition of Borrower or any of its Subsidiaries, in any court
                  or before any governmental authority or arbitration board or
                  tribunal, and no action, suit, proceeding or investigation
                  shown on Exhibit J attached hereto, except as indicated on
                  such Exhibit J, involves the possibility of materially and
                  adversely affecting the Properties, business, prospects,
                  profits or condition (financial or otherwise) of Borrower or
                  the ability of Borrower to perform this Agreement. Neither
                  Borrower nor any of its Subsidiaries is in default with
                  respect to any order, writ, injunction, judgment, decree or
                  rule of any court, governmental authority or arbitration board
                  or tribunal.

         (c)      Title to Properties. Subject to the statutory right of the MMS
                  to approve the acquisition of an Offshore Platform and related
                  oil and gas Properties, each Borrower and each of its
                  Subsidiaries has good, indefeasible and marketable title to
                  and fee simple ownership of, or valid and subsisting leasehold
                  interests in, all of its oil and gas Properties and Real
                  Property, and good title to all of its other Property, in each
                  case, free and clear of all Liens except Permitted Liens.
                  Exhibits C and R attached hereto identifies all of the
                  Offshore Platforms, other oil and gas Properties and Real
                  Property leased or owned by Borrower and its Subsidiaries and,
                  if leased, identifies the lessor thereof.

         (d)      Financial Statements: Fiscal Year. The Consolidated balance
                  sheet of Borrower and such other Persons described therein
                  (including the accounts of all Subsidiaries for the respective
                  periods during which a Subsidiary relationship existed) as of
                  November 30, 2001 and the related statements of income,
                  changes in stockholder's equity, and changes in cash flow for
                  the periods ended on such dates, have been prepared in
                  accordance with GAAP (except for changes in application in
                  which Borrower's independent certified public accountants
                  concur), and present fairly the financial positions of
                  Borrower and its Subsidiaries at such dates and the results of
                  Borrower's operations for such periods. Except as disclosed in
                  Schedule W hereto, since November 30, 2001 there has been no
                  material change in the condition, financial or otherwise, of
                  Borrower, its Subsidiaries and such other Persons as shown on
                  the Consolidated balance sheet as of such date and no change
                  in the aggregate value of Equipment and other Property owned
                  by Borrower or its Subsidiaries or such other Persons, except
                  as otherwise disclosed in the footnotes to such financial
                  statements and changes in the ordinary course of business,
                  which individually or in the aggregate has not been materially
                  adverse. The fiscal year of Borrower and each of its
                  Subsidiaries ends on December 31 of each year.

         (e)      Full Disclosure. The financial statements referred to in
                  Section 7.1(n), do not, nor does this Agreement or any other
                  written statement of Borrower to Lender (including, without
                  limitation, Borrower's filings, if any, with the Securities
                  and Exchange Commission), contain any untrue statement of a
                  material fact or omit a material fact necessary to make the
                  statements contained therein or herein not misleading. There
                  is no fact which Borrower has failed to disclose to Agent or
                  Lenders in writing which materially affects adversely or, so
                  far as Borrower can now foresee, will materially affect
                  adversely the Properties, business, prospects,



                                       57


                  profits, or condition (financial or otherwise) of Borrower or
                  any of its Subsidiaries or the ability of Borrower or its
                  Subsidiaries to perform this Agreement.

         (f)      ERISA. Except as disclosed in Exhibit K attached hereto, there
                  are no Pension Plans or Multiemployer Plans and no fact exists
                  that could result in any material liability (other than as
                  disclosed on Borrower's financial statements) to Borrower
                  relating to any former Plan. No Reportable Event has occurred
                  with respect to any Pension Plan that is not a Multiemployer
                  Plan. No Prohibited Transaction has occurred. The PBGC has not
                  instituted proceedings to terminate any Pension Plan. No ERISA
                  Affiliate nor any duly appointed administrator of a Pension
                  Plan has (i) incurred any liability to the PBGC with respect
                  to a Pension Plan other than for premiums not yet due and
                  payable, or (ii) instituted or intends to institute
                  proceedings under Section 4041(c) of ERISA to terminate any
                  Pension Plan, or (iii) instituted proceedings to withdraw from
                  any Pension Plan that is a Multiemployer Plan. No "accumulated
                  funding deficiency" within the meaning of Section 302(a)(2) of
                  ERISA exists with respect to any Pension Plan. No liability
                  has been incurred by any ERISA Affiliate which remains
                  unsatisfied for any taxes or penalties, with respect to any
                  Plan that is not a Multiemployer Plan or, to the best of
                  Borrower's knowledge and belief, with respect to any
                  Multiemployer Plan. No litigation is pending or, to the
                  Borrower's knowledge, threatened concerning or involving any
                  Plan. No amendment to any Pension Plan has been adopted such
                  that security is required to be given pursuant to IRC Section
                  401(a)(29) and no lien exists under IRC Section 412(n) with
                  respect to any Plan. Except as shown on Exhibit K attached
                  hereto with respect to the date and using the assumptions
                  described thereon, and to the best of Borrower's knowledge and
                  belief, no unfunded or unreserved liability exists for
                  benefits under any Plan that would have a material adverse
                  effect on the business or finances of Borrower. No ERISA
                  Affiliate contributes to, has contributed to, or is or has
                  been obligated to contribute to, any Multiemployer Plan. No
                  ERISA Affiliate maintains, or has promised to maintain, any
                  Plan which provides medical benefits to an employee or the
                  employee's dependents after the employee terminates employment
                  other than as required by law.

         (g)      Taxes. The federal tax identification numbers for Cal Dive,
                  ERT, Aquatica and Canyon are 95-3409686, 76-0413713,
                  72-1396623 and 76-0515050, respectively. Borrower and its
                  Subsidiaries each has filed all federal, state and local tax
                  returns and other reports it is required by law to file and
                  has paid, or made provision for the payment of, all taxes,
                  assessments, fees and other governmental charges that are due
                  and payable. The provision for taxes on the books of Borrower
                  and its Subsidiaries are adequate for all years not closed by
                  applicable statutes, and for its current fiscal year. There
                  are no material unresolved questions or claims concerning any
                  tax liability of Borrower except as described in Exhibit L
                  attached hereto. None of the transactions contemplated hereby
                  or under any agreements referred to hereunder will result in
                  any material tax liability for Borrower or result in any other
                  material adverse tax consequence for Borrower. Exhibit M
                  attached hereto contains an accurate list of all taxing
                  authorities to which Borrower and its Subsidiaries and their
                  respective Properties are subject. No Properties of



                                       58


                  Borrower or its Subsidiaries are or could become subject to
                  any Lien in favor of any such taxing authorities for
                  nonpayment of taxes, except as specified on Exhibit M attached
                  hereto.

         (h)      Labor Relations. Except as described on Exhibit N attached
                  hereto, neither Borrower nor any of its Subsidiaries is a
                  party to any collective bargaining agreement, and there are no
                  material grievances, disputes or controversies with any union
                  or any other organization of Borrower's employees, or threats
                  of strikes, work stoppages or any asserted pending demands for
                  collective bargaining by any union or organization.

         (i)      Compliance With Laws. Except as disclosed on Exhibit O
                  attached hereto as to existing violations of Environmental
                  Laws (the "Existing Environmental Violations"), Borrower has
                  duly complied in all material respects with, and its Property,
                  business operations and leaseholds are in compliance in all
                  material respects with, the provisions of all federal, state
                  and local laws, rules, regulations orders, citations and final
                  and enforceable notices applicable to Borrower, its Properties
                  or the conduct of its business, including, without limitation,
                  OSHA, Environmental Laws, the Securities Act of 1933, the
                  Securities Exchange Act of 1934, the Fair Labor Standards Act,
                  laws relating to income, unemployment, payroll or social
                  security taxes and Plans under ERISA, the Flood Disaster
                  Protection Act of 1973, the Consumer Credit Protection Act,
                  the Federal Trade Commission Act, statutes creating and
                  governing the Bureau of Alcohol, Tobacco and Firearms, and any
                  and all state statutes or pronouncements addressing, or
                  related to, subjects the same as or comparable to those
                  covered by such enumerated federal statutes, and there have
                  been no citations, notices or orders of noncompliance issued
                  to Borrower or any of its Subsidiaries under any such law,
                  rule or regulation.

         (j)      Surety Obligations. Except as described in Exhibit P attached
                  hereto, Borrower is not obligated as surety or indemnitor
                  under any surety or similar bond or other contract issued or
                  entered into any agreement to assure payment, performance or
                  completion of performance of any undertaking or obligation of
                  any Person.

         (k)      No Defaults. No event has occurred and no condition exists
                  which would, upon the execution and delivery of this Agreement
                  or Borrower's performance hereunder, constitute a Default or
                  an Event of Default. Neither Borrower nor any of its
                  Subsidiaries is in default, and no event has occurred and no
                  condition exists which constitutes, or which with the passage
                  of time or the giving of notice or both would constitute, a
                  default in the payment of any Indebtedness to any Person for
                  Money Borrowed.

         (l)      Brokers. There are no claims for brokerage commissions,
                  finder's fees or investment banking fees in connection with
                  the transactions contemplated by this Agreement.



                                       59


         (m)      Business Locations. Agent for Process. During the preceding
                  three year period, Borrower has had no office, place of
                  business or agent for service of process located in any state
                  or county other than as shown on Exhibit C attached hereto.

         (n)      Trade Relations. There exists no actual or threatened
                  termination, cancellation or limitation of, or any
                  modification or change in, the business relationship between
                  Borrower and any customer or any group of customers whose
                  purchases individually or in the aggregate are material to the
                  business of Borrower, or with any material supplier, and there
                  exists no present condition or state of facts or circumstances
                  which would materially affect adversely Borrower or prevent
                  Borrower from conducting such business after the consummation
                  of the transaction contemplated by this Agreement in
                  substantially the same manner in which it has heretofore been
                  conducted.

                  capitalized leases of Borrower and Exhibit R attached hereto

         (p)      Investment Company Act. Borrower is not an "investment
                  company" or a company "controlled" by an "investment company",
                  within the meaning of the Investment Company Act of 1940, as
                  amended.

         (q)      OSHA and Environmental Compliance.

                  (i)      Except for the Existing Environmental Violations,
                           Borrower is in compliance with, and its facilities,

                           Recovery Act, Oil Pollution Act, 1990, all
                           Environmental Laws and all permits issued to Borrower

                           are not now any outstanding citations, notices or

                           citations, notices or orders of noncompliance that
                           may be issued to Borrower or relating to its

                           of any Environmental Laws.

         (r)      Reaffirmation. Each request for a Loan made by Borrower
                  pursuant to this Agreement or any of the other Loan Documents
                  shall constitute (i) an automatic representation and warranty
                  by Borrower to Agent and Lenders that there does not then
                  exist any Default or Event of Default unless otherwise
                  disclosed to Lender in writing and (ii) a reaffirmation as of
                  the date of said request that all of the representations and
                  warranties of Borrower contained in this Agreement and the
                  other Loan Documents are true in all material respects except
                  for any changes in the nature of Borrower's business or
                  operations that would render the information contained in any
                  exhibit attached hereto either inaccurate or incomplete, so
                  long as Agent has consented to such changes in writing or such
                  changes are expressly permitted by this Agreement.

         Section 7.3 Survival of Representations and Warranties. Borrower
covenants, warrants and represents to Agent and Lenders that all representations
and warranties of Borrower contained in this Agreement or any of the other Loan

and the other Loan Documents, and shall survive the execution, delivery and
acceptance thereof by Agent and Lenders and the parties thereto and the closing
of the transactions described therein or related thereto until four (4) years
and one (1) day after all of the Obligations have been paid in full.

                 ARTICLE 8. COVENANTS AND CONTINUING AGREEMENTS

         Section 8.1 Affirmative Covenants. During the term of this Agreement,
and thereafter for so long as there are any Obligations to Lender, Borrower
covenants that, unless otherwise consented to by Agent in writing, it shall:

         (a)      Taxes and Liens. Pay and discharge, and cause each Subsidiary
                  to pay and discharge, all taxes, assessments and governmental
                  charges upon it, its income and Properties as and when such
                  taxes, assessments and charges are due and payable (and, if
                  requested by Agent, provide Agent with proof that Borrower or
                  such Subsidiary has done so), except and to the extent only
                  that such taxes, assessments and charges are being actively
                  contested in good faith and by appropriate proceedings,
                  Borrower maintains adequate reserves on its books therefor and
                  the nonpayment of such taxes, assessments and charges does not
                  result in a Lien upon any Properties or Borrower other than a
                  Permitted Lien. Borrower shall also pay and discharge any
                  lawful claims which, if unpaid, might become a Lien against
                  any of Borrower's Properties, except for Permitted Liens.
                  Borrower shall also make timely payment or deposit of all FICA
                  payments and



                                       61


                  withholding taxes required of it by the applicable laws, and
                  will, upon request, furnish Agent with proof satisfactory of
                  it that Borrower has made such payments or deposits.

         (b)      Tax Returns. File, and cause each Subsidiary to file, all
                  federal, state and local tax returns and other reports
                  Borrower or such Subsidiary is required by law to file and
                  maintain adequate reserves for the payment of all taxes,
                  assessments, governmental charges, and levies imposed upon it,
                  its income, or its profits, or upon any Property belonging to
                  it.

         (c)      Payment of Bank Charges. Pay to Agent or Lenders, on demand,
                  any and all reasonable and customary fees, costs or expenses
                  which Agent or Lenders pay to a bank or other similar
                  institution arising out of or in connection with (i) the
                  forwarding to Borrower or any other Person on behalf of
                  Borrower, by Agent or Lenders proceeds of loans made by
                  Lenders to Borrower pursuant to this Agreement and (ii) the
                  depositing for collection, by Agent or Lenders of any check or
                  item of payment received or delivered to Agent or Lenders on
                  account of the Obligations.

         (d)      Business and Existence. Preserve and maintain, and cause each
                  Subsidiary to preserve and maintain, its separate corporate
                  existence and all rights, privileges, and franchises in
                  connection therewith, and maintain, and cause each Subsidiary
                  to maintain, its qualification and good standing in all states
                  in which such qualification is necessary except in connection
                  with business combinations that result in a Subsidiary or a
                  Borrower being acquired by or merging with another Borrower.

         (e)      Maintain Properties. Maintain, and cause each Subsidiary to
                  maintain, its Properties in adequate operating condition and
                  make, and cause each Subsidiary to make, all necessary
                  renewals, repairs, replacements, additions and improvements
                  thereto.

         (f)      Compliance with Laws and Remediation of Existing Environmental
                  Violations. (i) Except for the Existing Environmental
                  Violations and the storage of the Lawful Substances, comply,
                  and cause each Subsidiary to comply, with all laws,
                  ordinances, governmental rules and regulations to which it is
                  subject, including, without limitation, all Environmental
                  Laws, and obtain and keep in force any and all licenses,
                  permits, franchises, or other governmental authorizations
                  necessary to the ownership or lease of its Properties or to
                  the conduct and operation of its business, except for
                  violations or failures to obtain that will not materially and
                  adversely affect the business, prospects, profits, Properties,
                  or condition (financial or otherwise) of Borrower.

                  Department of Labor and/or the Internal Revenue Service
                  pursuant to ERISA, and the regulations promulgated thereunder,
                  in connection with each of its Plans that is not a
                  Multiemployer Plan, (iii) notify Agent prior to any request by
                  any ERISA Affiliate for a waiver of the funding requirements
                  of IRC Section 412 or the commencement of any distress
                  termination pursuant to ERISA Section 4041(c) with respect to
                  any Pension Plan, (iv) notify Agent immediately of any

                  arising in connection with any of its Plans that is not a
                  Multiemployer Plan, which might constitute grounds for

                  administer such Plan, together with a statement, if requested

                  Multiemployer Plan, and (vi) furnish to Agent, promptly upon
                  Agent's request therefor, such additional information
                  concerning any Plan as may be reasonably requested.

                  business activities in which proper entries are made in
                  accordance with GAAP reflecting all its financial

                  a consolidation of offices or



                                       64

                           Borrower's business and review the adequacy and
                           effectiveness of such system on an annual basis.

                           state or local agency responsible in whole or in part
                           for environmental matters in the state in which the

                           entity hereinafter the "Authority"), then the
                           Borrower shall, within ten (10) Business Days, give
                           written notice of same to the Agent and furnish the
                           Agent a copy of the Environmental Complaint. Such
                           notice is not intended to create nor shall it create
                           any obligation upon Agent with respect thereto.

                  (v)      Promptly forward to Agent copies of any request for

                           Hazardous Substances at any other site owned,
                           operated or used by Borrower to dispose of Hazardous
                           Substances and shall continue to forward copies of
                           correspondence between Borrower and the Authority
                           regarding such claims to the Agent until the claim is
                           settled. The Borrower shall promptly forward to the
                           Agent copies of all documents and reports concerning
                           a Hazardous Discharge that the Borrower is required
                           to file under any Environmental Laws. Such
                           information is to be provided solely to allow the
                           Agent to protect Agent's security interest in the
                           Collateral and is not intended to create nor shall it
                           create any obligation upon Agent with respect
                           thereto.

                  (vi)     Respond promptly to any Hazardous Discharge or
                           Environmental Complaint and take all necessary action
                           in order to safeguard the health of any Person and to
                           avoid subjecting the Collateral or Real Property to
                           any



                                       67


                           Lien. Borrower shall be deemed to be taking all
                           necessary action only if, and for so long as, the
                           execution or enforcement of an Environmental
                           Complaint is, and continues to be, effectively stayed
                           and the Borrower maintains adequate reserves
                           therefore, which are properly reflected on Borrower's
                           Consolidated Financial Statements, the validity and
                           amount of the claims secured thereby are being
                           actively contested in good faith and by appropriate
                           lawful proceedings, and any Liens associated with the
                           Environmental Complaint do not, in the aggregate,
                           materially detract from the value of the Property of
                           Borrower or materially impair the use thereof in the
                           operation of Borrower's business. If Borrower shall
                           fail to so respond to any Hazardous Discharge or
                           Environmental Complaint or Borrower shall fail to
                           comply with any of the requirements of any
                           Environmental Laws where the failure to do so would
                           have a material adverse effect on its business,
                           condition (financial or otherwise), operations,
                           prospects or Properties, Agent may, but without the
                           obligation to do so, for the sole purpose of
                           protecting Agent's interest in Collateral after
                           giving Borrower prior written notice: (a) give such
                           notices or (b) enter onto the Real Property or
                           Vessels (or authorize third parties to enter onto the
                           Real Property or Vessels) and take such actions as
                           Agent(or such third parties as directed by the Agent)
                           deem reasonably necessary or advisable, to clean up,
                           remove, or mitigate any such Hazardous Discharge or
                           Environmental Complaint. All reasonable costs and
                           expenses incurred by Agent (or such third parties) in
                           the exercise of any such rights, including any sums
                           paid in connection with any judicial or
                           administrative investigation or proceedings, fines
                           and penalties, together with interest thereon from
                           the date expended at the Applicable Annual Rate for
                           Base Rate Loans shall be paid upon demand by the
                           Borrower, and until paid shall be added to and become
                           a part of the Obligations secured by the Liens
                           created by the terms of this Agreement or any other
                           agreement between Agent or Lenders and Borrower.

                  (vii)    Promptly upon the written request of the Agent, in
                           connection with any Hazardous Discharge or
                           Environmental Complaint as described in clause (vi)
                           immediately preceding, provide to Agent, at the
                           Borrower's expense, with an environmental site
                           assessment or environmental audit report prepared by
                           an environmental engineering firm acceptable to Agent
                           to assess with a reasonable degree of certainty the
                           existence of a Hazardous Discharge and the potential
                           costs in connection with abatement, cleanup and
                           removal of any Hazardous Substances required as a
                           result of the Hazardous Discharge or Environmental
                           Complaint. Any investigation of or response to such
                           Hazardous Discharge proposed and acceptable to an
                           appropriate Authority that is charged to oversee the
                           clean-up of such Hazardous Discharge shall be
                           acceptable to the Agent.

                  (viii)   Defend and indemnify Agent and Lenders and hold Agent
                           and Lenders, and their respective employees, agents,

                           fines and penalties, including attorney's fees,
                           suffered or incurred by Agent or Lenders under or on
                           account of any Environmental Laws, including, without
                           limitation, the assertion of any Lien thereunder,
                           with respect to any Hazardous Discharge, the presence
                           of any Hazardous Substances affecting its business
                           and operations, the Real Property or the Vessels,
                           whether or not the same originates or emerges from
                           the Real Property or any contiguous real estate or
                           the Vessels, including any loss of value of the Real
                           Property as a result of the foregoing. Borrower's
                           obligations under this Section 8.1(u) shall arise
                           upon the discovery of the presence of any Hazardous
                           Substances at the Real Property or on board the
                           Vessels that would have a material adverse effect on
                           Borrower's business, condition (financial or
                           otherwise), operations, prospects or Properties, or
                           Borrower's use of Hazardous Substances in its
                           business and operations in a manner that would have a
                           material adverse effect on its business, condition

                           any action in connection with the presence of any
                           Hazardous Substances. Borrower's obligation and the
                           indemnification hereunder shall survive the
                           termination of this Agreement.

                  reasonable terms which are fully disclosed to Agent and are no

                  favor of Agent or Lenders; (ii) Liens for taxes (excluding any
                  Lien imposed pursuant to any of the provisions of ERISA) not
                  yet due or being contested as permitted by Section 8.1(a), but
                  only if in Agent's sole discretion and judgment such Lien does

                  Lien in the Collateral; (iii) Liens securing the claims or

                  for labor, materials, supplies, injuries or rentals incurred
                  in the ordinary course of Borrower's business, but only if the
                  payment thereof is not at the time required and only if such
                  Liens are junior to the Liens in favor of Agent, or if, and
                  for so long as, the execution or other enforcement of such
                  Liens is, and continues to be, effectively stayed, the
                  validity and amount of the claims secured thereby are being
                  actively contested in good faith and by appropriate lawful
                  proceedings, and such Liens do not, in the aggregate,
                  materially detract from the value of the Property of Borrower

                  Borrower's business; (iv) Liens resulting from deposits made
                  in the ordinary course of business in connection with

                  other similar non-tax Liens arising in connection with court
                  proceedings, but only if and for so long as the execution or
                  other enforcement of such Liens is and continues to be
                  effectively stayed and bonded on appeal in a manner
                  satisfactory to Agent for the full amount thereof, the
                  validity and amount of the claims secured thereby are being
                  actively contested in good faith and by appropriate lawful
                  proceedings and such Liens do not, in the aggregate,
                  materially detract from the value of the Property of Borrower
                  or materially impair the use thereof in the operation of
                  Borrower's business; (vi) Purchase Money Liens securing
                  Permitted Purchase Money Indebtedness which is not incurred in
                  violation of Section 8.2(c); (vii) contractual rights,
                  reservations, exceptions, easements, rights of way, and other
                  similar encumbrances affecting Real Property other than as
                  described in Exhibit V attached hereto; provided, that, in
                  Agent's judgment, which will be exercised in good faith, they
                  do not in the aggregate materially detract from the value of
                  said Properties or materially interfere with their use in the
                  ordinary conduct of Borrower's business and, if said Real
                  Property constitutes Collateral, Agent has consented thereto;
                  (viii) Liens securing Indebtedness of a Subsidiary to Borrower
                  or another Subsidiary; (ix) such other Liens as described on
                  Exhibit V attached hereto; and (x) such other Liens as Agent
                  may hereafter approve in writing.

                           finances.

         (m)      Litigation. Borrower, or any Affiliate, shall challenge or
                  contest in any action, suit or proceeding the validity or
                  enforceability of this Agreement or any of the other Loan
                  Documents, the legality or enforceability of any of the
                  Obligations or the perfection or priority of any Lien granted
                  to Agent.

         (n)      Criminal Forfeiture. Borrower shall be criminally indicted or
                  convicted under any law that could lead to a forfeiture of any
                  material Property of Borrower.



                                       79


         (o)      Judgments. Any money judgment, writ of attachment or similar
                  process is entered or filed against Borrower or any of its
                  Property and results in the creation or imposition of any Lien
                  that is not a Permitted Lien.

         Section 10.2 Acceleration of the Obligations. Without in any way
limiting the right of Agent to demand payment of any portion of the Obligations
payable on demand in accordance with Section 3.6 hereof, upon or at any time
after the occurrence of an Event of Default as above provided, all or any
portion of the Obligations due or to become due from Borrower to Lenders
(whether under this Agreement, or any of the other Loan Documents or otherwise)
shall, at Agent's option (or, in the case of an Event of Default under Section
10.1(j) hereof, immediately upon the occurrence thereof), become at once due and
payable without presentment, demand, protest, notice of dishonor, notice of
default, notice of intent to accelerate, notice of acceleration, or any other
notice whatsoever, and Borrower shall forthwith pay to Lenders, in addition to
any and all sums and charges due, the entire principal of and interest accrued
on the Obligations.

         Section 10.3 Remedies. Upon and after the occurrence of an Event of
Default, Agent shall have and may exercise from time to time the following
rights and remedies:

         (a)      All of the rights and remedies of a secured party under the
                  Code, or under other applicable law, and all other legal and
                  equitable rights to which Agent may be entitled, all of which
                  rights and remedies shall be cumulative, and none of which
                  shall be exclusive, and shall be in addition to any other
                  rights or remedies contained in this Agreement or any of the
                  other Loan Documents.

         (b)      The right to take immediate possession of the Collateral, and
                  (i) to require Borrower to assemble the Collateral, at
                  Borrower's expense, and make it available to Agent at a place
                  designated by Agent which is reasonably convenient to both
                  parties, and (ii) to enter any of the premises of Borrower or
                  wherever any of the Collateral shall be located, and to keep
                  and store the same on said premises until sold (and if said
                  premises be the Property of Borrower, Borrower agrees not to
                  charge Agent for storage thereof).

         (c)      The right to sell or otherwise dispose of all or any Inventory
                  or Equipment in its then condition, or after any further
                  manufacturing or processing thereof, at public or private sale
                  or sales, with such notice as may be required by law, in lots
                  or in bulk, for cash or on credit, all as Agent, in its
                  discretion, may deem advisable. Borrower agrees that ten days
                  written notice to Borrower of any public or private sale or
                  other disposition of such Collateral shall be reasonable
                  notice thereof, and such sale shall be at such locations as
                  Agent may designate in said notice. Agent shall have the right
                  to conduct such sales on Borrower's premises, without charge
                  therefor, and such sales may be adjourned from time to time in
                  accordance with applicable law. Agent shall have the right to
                  sell, lease or otherwise dispose of such Collateral, or any
                  part thereof, for cash, credit or any combination thereof, and
                  Agent and Lenders may purchase all or any part of such
                  Collateral at public or, if permitted by law, private sale
                  and, in lieu of actual payment of such purchase price, may set
                  off the amount of such price against the Obligations.



                                       80


         (d)      Agent is hereby granted a license or other right to use,
                  without charge, Borrower's labels, patents, copyrights, rights
                  of use of any name, trade secrets, trade names, trademarks and
                  advertising matter, or any Property of a similar nature, as it
                  pertains to the Collateral, in advertising for sale and
                  selling any Collateral and Borrower's rights under all
                  licenses and all franchise agreements shall inure to Agent's
                  benefit.

         (e)      The proceeds realized from the sale of any Collateral may be
                  applied, after allowing two Business Days for collection,
                  first to the costs, expenses and reasonable attorneys' fees
                  incurred by Agent in collecting the Obligations, in enforcing
                  the rights of Agent and Lenders under the Loan Documents and
                  in collecting, retaking, completing, protecting, removing,
                  storing, advertising for sale, selling and delivery any of the
                  Collateral; secondly, to interest due upon any of the
                  Obligations; and thirdly, to the principal of the Obligations.

         (f)      With respect to the face amount of all LC Guaranties and
                  Letters of Credit issued by Agent may, at its option, require
                  Borrower to deposit with Lender funds equal to such face
                  amount, and if Borrower fails to promptly make such deposit,
                  Lenders may advance such amount as a Revolving Loan (whether
                  or not such advance would cause the outstanding balance of
                  Revolving Loans to exceed the Borrowing Base). Any such
                  deposit or advance shall be held by Agent as a reserve to fund
                  future payments on such LC Guaranties and future drawings
                  against such Letters of Credit. At such time as all LC
                  Guaranties have been paid or terminated and all Letters of
                  Credit issued by Issuing Bank have been drawn upon or expired,
                  any amounts remaining in such reserve shall be applied against
                  any outstanding Obligations, or to the extent all Obligations
                  have been indefeasibly paid in full, returned to Borrower.

         Section 10.4 Remedies Cumulative: No Waiver. All covenants, conditions,
provisions, warranties, guaranties, indemnities, and other undertakings of
Borrower contained in this Agreement and the other Loan Documents, or in any
document referred to herein or contained in any agreement supplementary hereto
or in any schedule or contained in any other agreement between Agent or Lenders,
or and Borrower, heretofore, concurrently, or hereafter entered into, shall be
deemed cumulative to and not in derogation or substitution of any of the terms,
covenants, conditions, or agreements of Borrower herein contained or of any of
the other rights or remedies of Agent or Lenders as provided by any applicable
law or in equity. The failure or delay of Agent or Lenders to exercise or
enforce any rights, Liens, powers, or remedies hereunder or under any of the
aforesaid agreements or other documents or security or Collateral or other
rights or remedies shall not operate as a waiver of such Liens, rights, powers
and remedies, but all such Liens, rights, powers, and remedies shall continue in
full force and effect until all Loans and all other Obligations owing or to
become owing from Borrower to Agent or Lenders shall have been fully satisfied,
and all Liens, rights, powers, and remedies herein provided for are cumulative
and none are exclusive.



                                       81


                             ARTICLE 11. THE AGENT

         Section 11.1 Authorization and Action. Each Lender hereby appoints and
authorizes Agent to take such action on its behalf and to exercise such powers
under this Agreement, and the other Loan Documents as are delegated to Agent by
the terms hereof and thereof, together with such powers as are reasonably
incidental thereto. As to any matters not expressly provided for by this
Agreement and the other Loan Documents (including, without limitations
enforcement or collection of the Notes), Agent shall not be required to exercise
any discretion or take any action, but shall be required to act or to refrain
from acting (and shall be fully protected in so acting or refraining from
acting) upon the instructions of the Majority Lenders, and such instructions
shall be binding upon all Lenders; provided, however, that Agent shall not be
required to take any action which exposes Agent to personal liability or which
is contrary to this Agreement or the other Loan Documents or applicable law. To
the extent the Lenders do not receive such materials directly from Borrower,
Agent agrees to give each Lender promptly a copy of each notice, financial
statement or report given to it by Borrower pursuant to the terms of this
Agreement and the other Loan Documents.

         Section 11.2 Agent's Reliance, Etc. Neither Agent nor any of its
directors, officers, agents or employees shall be liable for any action taken or
omitted to be taken by it or them under or in connection with this Agreement or
the other Loan Documents, except for its or their own gross negligence or
willful misconduct. Without limitation of the generality of the foregoing,
Agent: (a) may treat the payee of any Note as the holder thereof until Agent
receives written notice of the assignment or transfer thereof signed by such
payee and in form satisfactory to Agent; (b) may consult with legal counsel,
independent public accountants and other experts selected by it and shall not be
liable for any action taken or omitted to be taken in good faith by it in
accordance with the advice of such counsel, accountants or experts; (c) makes no
warranty or representations to any Lender and shall not be responsible to any
Lender for any statements, warranties or representations made in or in
connection with this Agreement or the other Loan Documents; (d) shall not have
any duty beyond Agent's customary practices to ascertain or to inquire as to the
performance or observance of any of the terms, covenants or conditions of this
Agreement or the other Loan Documents on the part of any Loan Party or to
inspect the property (including the books and records) of any Loan Party; (e)
shall not be responsible to any Lender for the due execution, legality,
validity, enforceability, genuineness, sufficiency or value of this Agreement or
the other Loan Documents or any other instrument or document furnished pursuant
hereto or thereto; and (f) shall incur no liability under or in respect of this
Agreement or the other Loan Documents by acting upon any notice, consent,
certificate or other instrument or writing (which may be by telecopy, telegram,
cable or telex) believed in good faith by it to be genuine and signed or sent by
the proper party or parties.

         Section 11.3 Fleet and Affiliates. With respect to its commitment
hereunder to make Revolving Credit Loans, Fleet shall have the same rights and
powers under this Agreement and the other Loan Documents as any other Lender and
may exercise the same as though it were not Agent; and the term "Lender" or
"Lenders" shall, unless otherwise expressly indicated, include Fleet in its
individual capacity. Fleet and its Affiliates may lend money to, and generally
engage in any kind of business with, Borrower or any of its Subsidiaries and any
Person who may do business with or own Securities of Borrower or any such
Subsidiary, all as if Fleet were not Agent and without any duty to account
therefor to Lenders.



                                       82


         Section 11.4 Lender Credit Decision. Each Lender acknowledges that it
has, independently and without reliance upon Agent or any other Lender and based
on the financial statements referred to in Section 8.3 and such other documents
and information as it has deemed appropriate, made its own credit analysis and
decision to enter into this Agreement. Each Lender also acknowledges that it
will, independently and without reliance upon Agent 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.

         Section 11.5 Indemnification. Lenders agree to indemnify Agent (to the
extent not reimbursed by Borrower), ratably according to the respective
principal amounts of the Notes then held by each of them, from and against any
and all liabilities, obligations, losses, damages, penalties, actions,
judgments, suits, costs, expenses or disbursements of any kind or nature
whatsoever which may be imposed on, incurred by, or asserted against Agent in
any way relating to or arising out of this Agreement or any other Loan Document
or any action taken or omitted by Agent under this Agreement, provided that no
Lender shall be liable for any portion of such liabilities, obligations, losses,
damages, penalties, actions, judgments, suits, costs, expenses or disbursements
resulting from Agent's gross negligence or willful misconduct. Without
limitation of the foregoing, each Lender agrees to reimburse Agent promptly upon
demand for its ratable shares of any out-of-pocket expenses (including counsel
fees) incurred by 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 and each other Loan Document,
to the extent that Agent is not reimbursed for such expenses by Borrower.

         Section 11.6 Successor Agent. Agent may resign at any time by giving
written notice thereof to Lenders and Borrower. Upon any such resignation, the
Required Lenders shall have the right to appoint a successor Agent which shall
be reasonably acceptable to Borrower. If no successor Agent shall have been so
appointed by the Majority Lenders, and shall have accepted such appointment,
within 30 days after the retiring Agent's giving notice of resignation, then the
retiring Agent may, on behalf of the Lenders, appoint a successor Agent, which
shall be a commercial bank or financial institution organized under the laws of
the United States of America or of any State thereof and having a combined
capital and surplus of at least Five Hundred Million Dollars ($500,000,000).
Upon the acceptance of any appointment as Agent hereunder by a successor Agent,
such successor Agent shall thereupon succeed to and become vested with all the
rights, powers, privileges and duties of the retiring Agent, and the retiring
Agent shall be discharged from its duties and obligations under this Agreement
and the other Loan Documents. After any retiring Agent's resignation hereunder
as Agent, the provisions of this Section 11 shall inure to its benefit as to any
actions taken or omitted to be taken by it while it was Agent under this
Agreement and the other Loan Documents.

         Section 11.7 Communications to and from Agent.

         When any notice, approval, consent, waiver or other communication or
action is required or may be delivered by the Lenders hereunder or the other
Loan Documents, action by the Agent shall be effective for all purposes
hereunder; provided, that upon any occasion requiring or permitting an approval,
consent, waiver, election or other action on the part of the Lenders, unless
action by the Agent alone, or only upon instruction of all of the Lenders, is
expressly



                                       83


permitted or required hereunder, action shall be taken by the Agent for and on
behalf of or for the benefit of all the Lenders as provided in Section
11.1above. The Borrowers may rely on any communication from the Agent hereunder
or the other Loan Documents, and need not inquire into the propriety of or
authorization for such communication. Upon receipt by the Agent from the
Borrower or any Lender of any communication it will, in turn, promptly forward
such communication to the Lenders; provided, however, that the Agent shall not
be liable for any costs, expenses or losses arising from any failure to so
forward any such communication.

         Section 11.8 Limitations of Agency.

         Notwithstanding anything in the Loan Documents, expressed or implied,
it is agreed by the parties hereto, that the Agent will act under the Loan
Documents as Agent solely for the Lenders and only to the extent specifically
set forth herein, and will, under no circumstances, be considered to be an agent
or fiduciary of any nature whatsoever in respect to any other person.

         Section 11.9 No Representations or Warranty.

         (a)      No Lender (including the Agent) makes to any other Lender any
                  representation or any warranty, expressed or implied, or
                  assumes any responsibility with respect to the Loan or the
                  execution, construction or enforceability of the Loan
                  Documents or any instrument or agreement executed by the
                  Borrower or any other Person in connection therewith.

         (b)      The Agent takes no responsibility for the accuracy or
                  completeness of any information concerning the Borrower
                  distributed by the Agent in connection with the Loan nor for
                  the truth of any representation or warranty given or made
                  herein, nor for the validity, effectiveness, adequacy or
                  enforceability of this Agreement or any of the other Loan
                  Documents.

         Section 11.10 Distribution.

         The Agent shall be responsible for promptly distributing each Lender's
share of all net amounts received by the Agent under any of the Loan Documents
pursuant to the terms of the Loan Documents. Each Lender shall be responsible
for designating by written notice to the Agent the account to which such
distribution shall be deposited.

         Section 11.11 Limitation of Suits.

         All rights of action and claims under this Agreement and the other Loan
Documents of the Lenders shall be prosecuted and enforced only by the Agent. The
Lenders agree that they shall not independently institute any proceedings,
judicial or otherwise, to enforce their rights against the Borrowers under this
Agreement and the other Loan Documents. However, notwithstanding anything
contained in this Section 11.11, the Lenders shall always retain their ability
to retain independent counsel and to protect their rights under this Agreement
and the other Loan Documents.

         Section 11.12 Right of Setoff.



                                       84


         Upon the occurrence and during the continuation of any Event of
Default, the Lenders each are hereby authorized at any time and from time to
time, without notice to the Borrower (any such notice being expressly waived by
the Borrower), to setoff and apply any and all deposits (general or special,
time or demand, provisional or final, whether or not such setoff results in any
loss of interest or other penalty, and including without limitation all
certificates of deposit) at any time held by the Lenders and all of the
indebtedness arising in connection with this Agreement irrespective of whether
or not such Lender will have made any demand under this Agreement, the Note or
any other Loan Document. The Borrower also hereby grants to each of the Lenders
a security interest in and hereby transfers, assigns, sets over and conveys to
each of the Lenders, as security for payment of the Loan, all such deposits,
funds or property of the Borrower or indebtedness of any Lender to the Borrower.
Should the right of any Lender to realize funds in any manner set forth
hereinabove be challenged and any application of such funds be reversed, whether
by court order or otherwise, the Lenders shall make restitution or refund to the
Borrower pro rata in accordance with their respective portions of the Loan. Each
Lender agrees to promptly notify the Borrower and the Agent after any such
setoff and application, provided that the failure to give such notice will not
affect the validity of such setoff and application. The rights of the Agent and
the Lenders under this Section 11.12 are in addition to other rights and
remedies (including without limitation other rights of setoff) which the Agent
or the Lenders may have. Nothing contained herein shall affect the right of any
Lender to exercise, and retain the benefits of exercising, any such right with
respect to any other indebtedness or obligation of the Borrower to such Lender.

                           ARTICLE 12. MISCELLANEOUS

including, without limitation, any Losses caused by the negligence of such
Indemnified Person, but not including any Losses caused by the gross negligence
or willful misconduct of such Indemnified Person, and Borrower shall reimburse
Agent and Lenders and each other Indemnified Person for any expenses (including
in connection with the investigation of, preparation for or defense of any
actual or threatened claim, action or proceeding arising therefrom, including
any such costs of responding to discovery requests or subpoenas, regardless of
whether Agent and Lenders or such other Indemnified Person is a party thereto).
Without limiting the generality of the foregoing, this indemnity shall extend to
any claims asserted against Agent and Lenders or any other Indemnified Person by
any Person under any Environmental Laws or similar laws by reason of Borrower's
or any other Person's failure to comply with laws applicable to solid or
hazardous waste materials or other toxic substances. Borrower may select counsel
with respect to any Losses; provided, however, each Indemnified Person shall
have the right to monitor the progress of any claims, suits and administrative
proceedings defended by Borrower hereunder with counsel of such Indemnified
Person's choice, or conduct its defense through counsel of such Indemnified
Person's choice, in the event that (i) such Indemnified Person determines in
good faith that the conduct of its defense by Borrower could be materially
prejudicial to such Indemnified Person's interests or that other reasonable
grounds exist which demonstrate a lack of effectiveness or high level of quality
in the conduct of such defense by Borrower, and (ii) prior to retaining such
counsel for such purpose, such Indemnified Person shall consult with Borrower
and shall attempt in good faith to agree upon counsel to conduct the defense on
behalf of Borrower and such Indemnified Person, and in each case the fees and
disbursements of such counsel shall be paid by Borrower; provided, however, that
if such mutual agreement is not reached within a reasonable time on selecting
counsel, then such Indemnified Person may retain its own counsel at Borrower's
expense. Notwithstanding any contrary provision of this Agreement, the
obligation of Borrower under this Section 12.2 shall survive the payment in full
of the Obligations and the termination of this Agreement.



                                       86


         Section 12.3 Reimbursement of Expenses. Without limiting Borrower's
obligations for payment of expenses as provided elsewhere in this Agreement or
in any other Loan Document, if, at any time or times prior or subsequent to the
date hereof, regardless of whether or not an Event of Default then exists or any
of the transactions contemplated hereunder are concluded, Agent or Lenders incur
any out-of-pocket expenses (including, without limitation, the fees and expenses
of Agent or Lenders' attorneys if Agent or Lenders retain legal counsel) in
connection with: (a) the negotiation and preparation of the Loan Documents, any
amendment or modification of any Loan Documents; or (b) the administration of
the Loan Documents and the transactions contemplated thereby; (c) any
litigation, contest, dispute, suit, proceeding or action (whether instituted by
Agent, Lenders, Borrower or any other Person) in any way relating to the
Collateral, any Loan Documents, Agent's, Lenders' and Borrower's relationship,
or Borrower's affairs; (d) any attempt to enforce any rights of Agent or Lenders
against Borrower or any other Person which may be obligated to Agent or Lenders
by virtue of any Loan Documents, including, without limitation, the Account
Debtors; (e) the exercise or enforcement of any rights, remedies or privileges
of Lender under the Loan Documents or applicable law; (f) the analysis of
information received in connection with any Loan Documents; (g) the audit or
appraisal of any Collateral or Borrower's books and records; (h) the granting of
any consents or waivers requested in connection with the Loan Documents; (i) the
collection of any Obligations; or (j) any attempt to inspect, verify, protect,
preserve, restore, collect, sell, liquidate or otherwise dispose of or realize
upon the Collateral; then, in any such event, all expenses, costs, charges and
other fees incurred by Agent, Lender or their attorneys or relating to any of
the events or actions described in this Section 12.4 shall be payable, on
demand, by Borrower to Agent, and shall be additional Obligations hereunder
secured by the Collateral. Without limiting the generality of the foregoing,
such expenses, costs, charges and fees may include: recording costs; appraisal
costs; accountants' fees, costs and expenses; court costs and expenses;
photocopying and duplicating expenses; court reporter fees, costs and expenses;
attorney and paralegal fees, costs and expenses; long distance telephone
charges; air express charges; telegram and facsimile charges; wire transfer
fees; secretarial overtime charges; and expenses for travel, lodging and food.
Additionally, if any taxes (excluding taxes imposed upon or measured by the net
income of Agent or Lenders) shall be payable on account of the execution or
delivery of any of the Loan Documents, or the creation of any of the Obligations
hereunder, by reason of any existing or hereafter enacted federal or state
statute, Borrower will pay all such taxes, including, but not limited to, any
interest and penalties thereon, and will indemnify and hold Lender harmless from
and against liability in connection therewith. Notwithstanding anything else
contained in this Agreement, Borrower shall have no obligation to reimburse or
indemnify any Lender for its costs, expenses or losses if they arise out of an
action by Borrower to enforce such Lender's several obligations under this
Agreement and Borrower is successful in such an action.

         Section 12.4 Indulgences Not Waivers. Agent's failure, at any time or
times hereafter, to require strict performance by Borrower of any provision of
this Agreement shall not waive, affect or diminish any right of Agent thereafter
to demand strict compliance and performance therewith. Any suspension or waiver
by Agent of an Event of Default by Borrower under this Agreement or any of the
other Loan Documents shall not suspend, waive or affect any other Event of
Default by Borrower under this Agreement or any of the other Loan Documents,
whether the same is prior or subsequent thereto and whether of the same or of a
different type. None of the undertakings, agreements, warranties, covenants and
representations of Borrower contained in this Agreement or any of the other Loan
Documents and no Event of Default by



                                       87


Borrower under this Agreement or any of the other Loan Documents shall be deemed
to have been suspended or waived by Agent, unless such suspension or waiver is
by an instrument in writing specifying such suspension or waiver and is signed
by a duly authorized representative of Agent and sent to Borrower.

         Section 12.5 Severability. Wherever possible, each provision of this
Agreement shall be interpreted in such manner as to be effective and valid under
applicable law, but if any provision of this Agreement shall be prohibited by or
invalid under applicable law, such provision shall be ineffective only to the
extent of such prohibition or invalidity, without invalidating the remainder of
such provision or the remaining provisions of this Agreement.

         Section 12.6 Modification of Agreement; Sale of Interest.

         (a)      The Loan Documents constitute the complete agreement between
                  the parties with respect to the subject matter hereof and may
                  not be modified, altered or amended except by an agreement in
                  writing signed by Borrower, Majority Lenders and, if required
                  by the terms hereof, Agent. No Borrower may sell, assign or
                  transfer any of the Loan Documents, or any of the Obligations,
                  or any portion thereof, including without limitation, any
                  Borrower's rights, title, interests, remedies, powers and
                  duties hereunder or thereunder. Each Borrower hereby consents
                  to Agent's and any Lender's sale of participation, assignment,
                  transfer or other disposition in accordance with the terms of
                  this Section 12.6, at any time or times, of any of the Loan
                  Documents or of any portion thereof or interest therein,
                  including, without limitation, Agent's and any Lender's
                  rights, title, interests, remedies, powers or duties
                  thereunder, whether evidenced in writing or not; Each Borrower
                  agrees that it will use its best efforts to assist and
                  cooperate with Agent and any Lender in any manner reasonably
                  requested by Agent or such Lender to effect the sale of
                  participation in or assignment of any of the Loan Documents or
                  of any portion thereof or interest therein, including, without
                  limitation, assistance in the preparation of appropriate
                  disclosure documents or placement memoranda and executing
                  appropriate amendments to the signature pages hereto to
                  reflect the addition of any Lenders and such Lender's
                  respective commitments. The foregoing notwithstanding, except
                  with respect to sales, assignments or transfers to Affiliates
                  under common control pursuant to which the selling, assigning
                  or transferring Lender retains its voting rights, no Lender
                  shall sell participate or assign, transfer or otherwise
                  dispose of any of the Loan Documents or any portion thereof or
                  interest therein, without the prior written consent of Agent,
                  which shall not be unreasonably withheld.

         (b)      In respect to any assignment by a Lender of its rights and
                  obligations under this Agreement (including, without
                  limitation, all or a portion of its Revolving Credit
                  Commitments, the Revolving Loans owed to it and the Note held
                  by it (i) each such assignment shall be of a uniform, and not
                  a varying, percentage of all rights and obligations, (ii)
                  except in the case of an assignment of all of a Lender's
                  rights and obligations under this Agreement, (A) the aggregate
                  amount of the Revolving Credit Commitments of the assigning
                  Lender being assigned pursuant to each such assignment
                  (determined as of the date of the Assignment and Acceptance



                                       88


                  with respect to such assignment) shall in no event be less
                  than $2,000,000, and in integral multiples of $1,000,000
                  thereafter, or such lesser amount as to which Borrower and the
                  Agent may consent to and (B) after giving effect to each such
                  assignment in the amount of the Revolving Credit Commitments
                  of the Assigning Lender shall in no event be less than
                  $2,000,000, (iii) the parties to each such assignment shall
                  execute and deliver to the Agent, for its acceptance, an
                  Assignment and Acceptance in the form of Exhibit Y hereto (an
                  "Assignment and Acceptance"), together with any Note subject
                  to such assignment and a processing and recordation fee of
                  $3,500, and (iv) any Lender may without the consent of
                  Borrower or the Agent, and without paying any fee, assign to
                  any Affiliate of such Lender that is a bank or financial
                  institution all of its rights and obligations under this
                  Agreement. The foregoing notwithstanding, no Person may become
                  a Lender or a Participating Lender hereunder, unless such
                  Person is a financial institution having stockholders' equity
                  (or the equivalent) of at least One Hundred Million Dollars
                  ($100,000,000). Upon such execution, delivery, acceptance and
                  recording, from and after the effective date specified in such
                  Assignment and Acceptance (x) the assignee thereunder shall be
                  a party hereto and, to the extent that rights and obligations
                  hereunder have been assigned to it pursuant to such Assignment
                  and Acceptance, have the rights and obligations of a Lender
                  hereunder and (y) the Lender assignor thereunder shall, to the
                  extent that rights and obligations hereunder 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 of the remaining portion of an
                  assigning Lender's rights and obligations under this
                  Agreement, such Lender shall cease to be a party hereto). If,
                  pursuant to this Section 12.6, any interest in this Agreement
                  or any Revolving Credit Loan or any Note is transferred to any
                  transferee which is organized under the laws of any
                  jurisdiction other than the United States or any state
                  thereof, the transferor Lender shall cause such transferee
                  (other than any Participating Lender), and may cause any
                  Participating Lender concurrently with the effectiveness of
                  such transfer, (a) to represent to the transferor Lender (for
                  the benefit of the transferor Lender, Agent and Borrower) that
                  under applicable law and treaties no Taxes will be required to
                  be withheld by Agent, Borrower or the transferor Lender with
                  respect to any payments to be made to such transferee in
                  respect of the Revolving Credit Loans, or the Notes, (b) to
                  furnish to the transferor Lender, Agent or Borrower either
                  U.S. Internal Revenue Service Form 4224 or U.S. Internal
                  Revenue Service Form 1001 (wherein such transfer claims
                  entitlement to complete exemption form U.S. federal
                  withholding tax on all interest payments hereunder), and (c)
                  to agree (for the benefit of the transferor Lender, Agent and
                  Borrower) to provide the transferor Lender, Agent and Borrower
                  a new Form 4224 or Form 1001 upon the obsolescence of any
                  previously delivered form and comparable statements in
                  accordance with applicable U.S. laws and regulations and
                  amendments duly executed and completed by such transferee, and
                  to comply from time to time with all applicable U.S. laws and
                  regulations with regard to such withholding tax exemption.



                                       89


         (c)      In addition to, and not in limitation of the foregoing,
                  Borrower acknowledges that if Fleet intends to sell, assign or
                  participate any of its Revolving Credit Commitments, Borrower
                  agrees to use its best efforts to assist Fleet in any respect
                  to any such sale, assignment or participation.

                  (i)      In the event any Lender assigns or otherwise
                           transfers all or any part of its Note any such Lender
                           shall so notify Borrower and Borrower shall, upon the
                           request of such Lender, issue new Notes in exchange
                           for the old Notes.

                  (ii)     Any Lender may at any time sell to one or more
                           commercial banks, financial institutions, or other
                           Persons not Affiliates of Borrower (a "Participating
                           Lender") participating interests in any Loans, the
                           Revolving Credit Commitments of that Lender and the
                           other interests of that Lender (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) Borrower 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 grant any participation under which the
                           Participating Lender shall have rights to approve any
                           amendment to or waiver of this Agreement or the Loan
                           Documents, except to the extent such amendment or
                           waiver would: (A) extend the final maturity date for
                           payment of the Loans in which such Participating
                           Lender is participating; (B) reduce the interest rate
                           or the amount of principal or fees applicable to the
                           Loans in which such Participating Lender is
                           participating; or (C) release all or substantially
                           all of the Collateral, except as expressly provided
                           herein. In those cases in which an Originating Lender
                           grants rights to a Participating Lender to approve
                           any amendment to or waiver of this Agreement or the
                           other Loan Documents respecting the matters described
                           in clauses (A) through (C) of the preceding sentence,
                           the relevant participation agreements shall provide
                           for a voting mechanism whereby a majority of the
                           amount of such Lender's portion of the Loans
                           (irrespective of whether held by such Lender or
                           participated) shall control the vote for all of such
                           Lender's portion of the Loans. In the case of any
                           participation, the Participating Lender shall not
                           have any rights under this Agreement or any of the
                           other Loan Documents entered into in connection
                           herewith (the Participating Lender's right against
                           such Lender in respect of such participation to be
                           those set forth in the participation or other
                           agreement executed by such Lender and the
                           Participating Lender relating thereto). In no event
                           shall any Participating Lender grant a participation
                           in its participation interest in the Loans without
                           the prior written consent of Agent, which approval
                           shall not be unreasonably withheld. All amounts
                           payable by Borrower hereunder shall be determined as
                           if the Originating Lender had not sold any such
                           participation, except that, if amounts outstanding
                           under this Agreement are due and unpaid, or shall
                           have been



                                       90


                           declared or shall have become due and payable upon
                           the occurrence of an Event of Default, each
                           Participating Lender shall be deemed to have the
                           right of set-off in respect of its participating
                           interest in amounts owing under this Agreement to the
                           same extent as if the amount of its participating
                           interest were owing directly to it as a Lender under
                           this Agreement.

                  (iii)    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 Board or U.S. Treasury Regulation
                           31 C.F.R. Section 203.14, and such Federal Reserve
                           Bank may enforce such pledge or security interest in
