                                  ARTICLE II

                                   Term Loan

         Section 2.1 Term Loan. Subject to the terms and conditions of this
Agreement, the Lender agrees to make the Term Loan to the Borrowers in one
Advance in an aggregate principal amount equal to the amount of the Lender's
Commitment.

         Section 2.2 Note. The obligation of the Borrowers to repay the Term
Loan and interest thereon shall be evidenced by the Note executed jointly and
severally by the Borrowers, payable to the order of the Lender, in the original
principal amount of the Lender's Commitment as originally in effect, and dated
the date hereof.

         Section 2.3 Interest. The unpaid principal amount of the Term Loan
shall bear interest at a varying rate per annum equal from day to day to the
lesser of (a) the Maximum Rate, or (b) the sum of the LIBOR Rate, plus 2.5%
(the "Interest Rate"). If at any time the Interest Rate for the Term Loan shall
exceed the Maximum Rate, thereby causing the interest accruing on the Term Loan
to be limited to the Maximum Rate, then any subsequent reduction in the
Interest Rate for the Term Loan shall not reduce the rate of interest on the
Term Loan below the Maximum Rate until the aggregate amount of interest accrued
on the Term Loan equals the aggregate amount of interest which would have
accrued on the Term Loan if the Interest Rate had at all times been in effect.

         Section 2.4 Repayment of Principal and Accrued Interest on the Term
Loan. The Borrowers jointly and severally agree to repay the unpaid principal
amount of the Term Loan and accrued and unpaid interest thereon as follows:

                  (a) four installments in the principal amount of $875,000
each, plus accrued and unpaid interest on the Term Loan, shall be due and
payable in the year 1999, the first installment of which shall be due and
payable on April 1, 1999, with subsequent installments to be due and payable on
each subsequent Payment Date until and including January 1, 2000; and
thereafter

                  (b) 23 subsequent installments in the principal amount of
$1,312,500 each, plus accrued and unpaid interest on the Term Loan shall be due
and payable thereafter, the first installment of which shall be due and payable
on April 1, 2000, with subsequent installments to be due and payable on each
subsequent Payment Date until and including October 1, 2005; and thereafter

                  (c) a final installment in the entire remaining outstanding
principal amount of the Term Loan, plus accrued and unpaid interest thereon,
shall be due and payable in full on the Maturity Date.

Notwithstanding the foregoing, any outstanding principal of the Term Loan and
(to the fullest extent permitted by law) any other amount payable by the
Borrowers under this Agreement or any other Loan Document that is not paid in
full when due (whether at stated maturity, by acceleration, or otherwise, and
without taking into account any applicable grace or cure periods) shall bear
interest



                                      13
<PAGE>   20


at the Default Rate for the period from and including the due date thereof to
but excluding the date the same is paid in full. Interest payable at the Default
Rate shall be payable from time to time on demand. In addition to the
foregoing, if any outstanding principal of the Term Loan and (to the fullest
extent permitted by law) any other amount payable by Borrowers under this
Agreement or any other Loan Documents is not paid in full within 10 days after
the date when due (whether at stated maturity, by acceleration, or otherwise,
and without taking into account any applicable grace or cure periods),
Borrowers jointly and severally agree to pay, upon demand by the Lender
therefor, a late payment fee in the amount of 5% of such amount not paid within
10 days of the date when due.

         Section 2.5 Additional Interest on the Term Loan. If the Lender is
required under regulations of the Federal Reserve Board to maintain reserves
with respect to liabilities or assets consisting of or including Eurocurrency
Liabilities, and if as a result thereof there is an increase in the cost to the
Lender of agreeing to make or making, funding or maintaining the Term Loan,
then the Borrowers shall from time to time, upon demand by the Lender, pay to
the Lender additional amounts as additional interest sufficient to compensate
the Lender for such increased cost. A certificate as to the basis for such
increased cost, in reasonable detail and specifying the amount requested
submitted to the Borrowers by the Lender shall be conclusive and binding absent
manifest error.

         Section 2.6 Use of Proceeds. The proceeds of the Term Loan shall be
used by the Borrowers to refinance $35,000,000 of senior indebtedness currently
outstanding to Subordinated Lender.

         Section 2.7 Commitment Fee. The Borrowers have paid to the Lender a
commitment fee equal to $175,000.

         Section 2.8 Co-Borrowers; Joint and Several Liability.

                  (a) Each Borrower acknowledges and agrees that it has
determined independently that, in light of the conduct of the business of
Borrowers as an integrated operation and a common enterprise that requires
financing on a basis permitting the availability of credit to each Borrower, it
will benefit specifically, directly and materially from the advances of credit
contemplated by the Lender's financing and that the value of the consideration
it is receiving from the Term Loan made hereunder is reasonably worth at least
the sum at which it is taken by such Borrower.

                  (b) It is expressly agreed and understood by each Borrower
that the Lender shall have no responsibility to inquire in the apportionment,
allocation, or disposition of the Term Loan to Borrowers. The Term Loan is to
be made for the collective account of Borrowers.

                  (c) Each Borrower hereby jointly, severally, irrevocably, and
unconditionally guarantees to the Lender the full and prompt payment of each of
the Obligations under the Loan Documents by each other Borrower and the
performance by each other Borrower of such Borrower's Obligations hereunder and
thereunder and shall fully and promptly perform all of the Obligations and
agrees, as a primary obligation, to indemnify the Lender on demand for and
against any loss



                                      14
<PAGE>   21



incurred by the Lender as a result of any voidable, unenforceable, or
ineffective provision herein or in any of the Loan Documents, for any reason
whatsoever, whether or not known to the Lender, or any Person, the amount of
such loss being in the amount to which the Lender would otherwise have been
entitled to recover from borrowers. This is a guaranty of payment and of
performance and not of collection.

                  (d) Each Borrower consents and agrees that the Lender may, at
any time and from time to time, without notice or demand, except as otherwise
required herein, whether before or after any actual or purported termination,
repudiation or revocation of any of the Loan Documents, including this
Agreement, by any one or more Borrowers, and without affecting the
enforceability or continuing effectiveness hereof as to each Borrower, agree
with one or more Borrowers or any other Person to: (i) supplement, restate,
compromise, modify, amend, increase, decrease, extend, discharge, renew,
accelerate, or otherwise change the time for payment or the terms of the
Obligations or any part thereof, including any increase or decrease of the
rate(s) of interest thereon; (ii) supplement, restate, modify, amend, increase,
decrease or waive, or enter into or give any agreement, approval, or consent
with respect to, the Obligations or any part thereof, or any of the Loan
Documents or any additional security or guarantees, or any condition, covenant,
default, remedy, right, representation or term thereof or thereunder; (iii)
accept new or additional instruments, documents or agreements in exchange for
or relative to any of the Loan Documents or the Obligations or any part
thereof, (iv) accept partial payments on the Obligations; (v) receive and hold
additional security or guarantees for the Obligations or any part thereof; (vi)
release, reconvey, terminate, waive, abandon, fail to perfect, subordinate,
exchange, substitute, transfer or enforce any security or guarantees, and apply
any security and direct the order or manner of the sale thereof as the Lender
in its sole and absolute discretion may determine; (vii) release any Person
from any personal liability with respect to the Obligations or any part
thereof; (viii) settle, discharge, release on terms satisfactory to the Lender
or by operation of applicable laws or otherwise liquidate or enforce any
Obligations and any security therefor or guaranty thereof in any manner,
consent to the transfer of any security and bid and purchase at any sale; (ix)
consent to the merger, change, or any other restructuring or termination of the
corporate existence of any Borrower and correspondingly restructure the
Obligations, and any such merger, change, restructuring or termination shall
not affect the liability of any Borrower or the continuing effectiveness
hereof, or the enforceability hereof with respect to all or any part of the
Obligations, or (x) take or refrain from taking any other action as the Lender,
in its sole and absolute discretion, may elect, or any or some of the
foregoing.

                  (e) The Lender may enforce this Agreement independently as to
each Borrower and independently of any other remedy or security the Lender at
any time may have or hold in connection with the Obligations or the Loan
Documents, or both, and it shall not be necessary for the Lender to marshal
assets in favor of any Borrower or any other Person or to proceed upon or
against or exhaust any security or remedy before proceeding to enforce this
Agreement. Each Borrower expressly waives any right to require the Lender to
marshal assets in favor of any Borrower, or any other Person or to proceed
against any other Borrower or any collateral provided by any Person, and agrees
that the Lender may proceed against one or more Borrowers or any Collateral in
such order as it shall determine in its sole and absolute discretion.




                                      15
<PAGE>   22


                  (f)  If any Borrower makes a payment in respect of the
Obligations, it shall have the rights of contribution and reimbursement set
forth below against the other Borrowers, and shall be indemnified as set forth
below; provided that no Borrower shall enforce its rights to any payment by
exercising its rights of contribution, reimbursement or indemnification unless
and until all the obligations shall have been paid in full. Each Borrower
waives any right of subrogation, contribution, reimbursement, and other rights
of indemnity it may have against any Obligated Party.

                  (g) If any Borrower makes a payment in respect of the
Obligations that is greater than its Pro Rata Percentage (hereinafter defined)
of the Obligations, calculated as of the date such payment is made, the
Borrower making such payment shall have the right to receive from each of the
other Borrowers, and the other Borrowers jointly and severally agree to pay to
such Borrower, when permitted by paragraph (f) above, an amount such that the
net payments made by the Borrowers in respect of the Obligations shall be
shared among the Borrowers pro rata in proportion to their respective Pro Rata
Percentages of the Obligations. The Borrowers hereby jointly and severally
indemnify each of the other Borrowers and jointly and severally agree to hold
each of them harmless from and against any and all amounts which any such
Borrower shall ever be required to pay in respect of the Obligations in excess
of such Borrower's respective Pro Rata Percentage of the Obligations.
Notwithstanding anything to the contrary contained in this paragraph or in this
Agreement, no liability or obligation of any Borrower that shall accrue
pursuant to this Agreement shall be paid nor shall it be deemed owed pursuant
to this Agreement or any Loan Documents unless and until all of the Obligations
shall be paid in full. As used herein, the term "Pro Rata Percentage" shall
mean, for each Borrower, the percentage derived by dividing (a) the amount by
which the fair saleable value of its assets on December 30, 1998, exceeds its
liabilities (such excess for each Borrower, its "Net Worth"), by (b) the Net
Worth of all of the Borrowers.

                  (h) The Lender may file a separate action or actions against
any Borrower, whether such action is brought or prosecuted with respect to any
security or against any other Person, or whether any other Person is joined in
any such action or actions. Each Borrower agrees that the Lender and any
Responsible Officer of any Borrower may deal with each other in connection with
the Obligations or otherwise, or alter any contracts or agreements now or
hereafter existing between any of them, in any manner whatsoever, all without
in any way altering or affecting the continuing efficacy of this Agreement.

                  (i) The Lender's rights hereunder shall be reinstated and
revived, and the enforceability of this Agreement shall continue, with respect
to any amount at any time paid on account of the Obligations that thereafter
shall be required to be restored or returned by the Lender, all as though such
amount had not been paid. The rights of the Lender created or granted herein
and the enforceability of this Agreement at all times shall remain effective to
cover the full amount to all the Obligations even though the Obligations,
including any part thereof or any other security or guaranty therefor, may be
or hereafter may become invalid or otherwise unenforceable as against any
Obligated Party or any Borrower and whether or not any Obligated Party or any
other Borrower shall have any personal liability with respect thereto.

                  (j) To the maximum extent permitted by applicable law, each
Borrower expressly waives any and all defenses now or hereafter arising or
asserted by reason of (i) any disability or



                                      16
<PAGE>   23


other defense of any other Borrower with respect to the Obligations, (ii) the
unenforceability or invalidity of any security or guaranty for the Obligations
or the lack of perfection or continuing perfection or failure of priority of
any security for the Obligations, (iii) the cessation for any cause whatsoever
of the liability of any other Borrower (other than by reason of the full
payment and performance of all Obligations), (iv) any failure of the Lender to
marshal assets in favor of any Borrower or any other Person, (v) any failure of
the Lender to give notice of sale or other disposition of Collateral to any
Borrower or any other Person, or any defect in any notice that may be given in
connection with any sale or disposition of Collateral, (vi) any failure of the
Lender to comply with applicable law in connection with the sale or other
disposition of any Collateral or other security for any Obligation, including
any failure of the Lender to conduct a commercially reasonable sale or other
disposition of any Collateral or other security for any Obligation, (vii) any
act or omission of the Lender or others that directly or indirectly results in
or aids the discharge or release of any Borrower any other Obligated Party, or
the Obligations or any security or guaranty therefor by operation of law or
otherwise, (viii) any law which provides that the obligation of a surety or
guarantor must neither be larger in amount nor in other respects more
burdensome than that of the principal or which reduces a surety's or
guarantor's obligation in proportion to the principal obligation, (ix) any
failure of the Lender to file or enforce a claim in any bankruptcy or other
proceeding with respect to any Person, (x) the election by the Lender of the
application or non-application of Section 1111(b)(2) of the Federal
Bankruptcy Code, (xi) any extension of credit or the grant of any lien under
Section 364 of the Federal Bankruptcy Code, (xii) any use of cash collateral
under Section 363 of the Federal Bankruptcy Code, (xiii) any agreement or
stipulation with respect to the provision of adequate protection in any
bankruptcy proceeding of any Person, (xiv) the avoidance of any lien in favor
of the Lender for any reason, or (xv) any action taken by the Lender that is
authorized by this Agreement or any Loan Document. Until such time, if any, as
all of the Obligations have been paid and performed in full and no portion of
any commitment of the Lender to any Borrower under any Loan Document remains in
effect, no Borrower shall have any right of subrogation, contribution,
reimbursement or indemnity, and each Borrower expressly waives any right to
enforce any remedy that the Lender may now have or hereafter may have against
any other Person, and waives the benefit of, or any right to participate in,
any Collateral now or hereafter held by the Lender. Each Borrower expressly
waives all presentments, demands for payment or performance, notices of
nonpayment, notices of intent to accelerate, notices of acceleration and
notices of nonperformance, protests, notices of protest, notices of dishonor
and all other notices or demands of any kind or nature whatsoever with respect
to the Obligations, and all notices of acceptance of this Agreement or of the
existence, creation or incurring of new or additional Obligations.

                  (k) To the fullest extent permitted by applicable law, each
Borrower expressly waives any suretyship defenses to the enforcement of this
Agreement or any rights of the Lender created or granted hereby or to the
recovery by any such Person including any other Obligated Party, against any
Borrower, or any other Person liable therefor of any deficiency after a
judicial or nonjudicial foreclosure or sale, even though such a foreclosure or
sale may impair the subrogation rights of Borrowers and may preclude Borrowers
from obtaining reimbursement or contribution from the other Borrowers. Each
Borrower expressly waives any defenses or benefits that may be derived pursuant
to or from Rule 31 of the Texas Rules of Civil Procedure, Section 17.001 of the
Civil Practice and Remedies Code and Chapter 34 of the Texas Business and
Commerce Code, as



                                      17
<PAGE>   24


amended, or comparable provisions of the laws of any other jurisdiction, and
all other suretyship defenses it otherwise might or would have under Texas law
or other applicable law.

                  (l) Each Borrower warrants and agrees that each of the
waivers and consents set forth in this Section 2.8 are made after consultation
with legal counsel and with full knowledge of their significance and
consequences, with the understanding that events giving rise to any defense or
right waived may diminish, destroy or otherwise adversely affect rights which
such Borrower otherwise may have against the other Borrowers, the Lender or
others, or against Collateral, and that, under the circumstances, the waivers
and consents herein given are reasonable and not contrary to public policy or
law. If any of the waivers or consents herein are determined to be contrary to
any applicable law or public policy, such waivers and consents shall be
effective to the maximum extent permitted by law.

                  (m) Each Borrower represents and warrants to the Lender that
(i) such Borrower has established adequate means of obtaining from the other
Borrowers on a continuing basis financial and other information pertaining to
the business, operations, and condition (financial and otherwise) of the other
Borrowers, and their property, and (ii) such Borrower now is and hereafter will
be familiar with the business, operations and condition (financial and
otherwise) of the other Borrowers, and their property. Each Borrower hereby
waives and relinquishes any duty on the part of the Lender to disclose to such
Borrower any matter, fact or thing relating to the business, operations or
condition (financial or otherwise) of the other Borrowers, or the property of
the other Borrowers, whether now or hereafter known by the Lender during the
term of this Agreement.

payment shall become due (each such payment made after such time on such due
date to be deemed to have been made on the next succeeding Business Day). The
Borrowers shall, at the time of making each such payment, specify to the Lender
the sums payable by the Borrowers under this Agreement and the other Loan
Documents to which such payment is to be applied (and in the event that the
Borrowers fail to so specify, or if a Default has occurred and is continuing,
the Lender may apply such payment to the Obligations in such order and manner
as it may elect in its sole discretion). Whenever any payment under this
Agreement or any other Loan Document shall be stated to be due on a day that is
not a Business Day, such payment may be made on the next succeeding Business
Day, and such extension of time shall in such case be included in the
computation of the payment of interest and letter of credit and facility fees,
as the case may be. Unless otherwise agreed to in writing or otherwise required
by applicable law, payments will be applied first to any unpaid collection
costs, late charges and other charges and fees, then to accrued, unpaid
interest, and any remaining amount to principal, provided, however, upon
delinquency or



                                      18

other default, the Lender reserves the right to apply payments among principal,
interest, late charges, collection costs and other charges and fees at its sole
discretion.

         Section 3.2 Prepayment. (a) The Borrowers may, upon at least thirty
days prior notice to the lender, prepay the term loan in whole on any Payment
Date or from time to time in part on any Payment Date, in each case with
accrued interest to the date of prepayment on the amount so prepaid, plus the
applicable Prepayment Make-Whole Amount, provided that each partial prepayment
shall be in the principal amount of $1,000,000 or an integral multiple thereof.
All notices under this Section shall be irrevocable and shall be given not
later than 11:00 A.M. on the day which is not less than the number of days
specified above for such notice.

                  (b) Prepayment Make-Whole Amounts are (i) payable as
liquidated damages, (ii) are a reasonable pre-estimate of the losses, costs and
expenses that the Lender would incur for any prepayment to which such
Prepayment Make-Whole Amount pertains, (iii) are not a penalty, (iv) will not
require claim for, or proof of, actual damages, and (v) the Lender's
determination thereof shall constitute prima facie evidence that such
determination is accurate and correct.

                  (c) if at any time any of the Borrowers or any Subsidiary
sells or otherwise disposes any of its fixed assets securing the Obligations or
issues or incurs any other Debt, the Borrower or Subsidiary involved shall
immediately (and in any event with three Business Days) notify the Lender in
writing of such event and pursuant to this Section 3.2(c), the Lender shall
have 30 days to direct the Borrowers that: (i) 100% of the proceeds received
shall be applied as a mandatory prepayment on the Note immediately (and in any
event within three Business Days) after receipt of notice of the Lender's
direction; or (h) the Lender has decided that no mandatory prepayment is
required as a result thereof. Nothing in this Section 3.2(c) shall be construed
as approval for any disposition of Collateral, which is expressly prohibited by
Section 9.8.

         Section 3.3 Taxes.

                  (a) All payments by the Borrowers of principal of and
interest on the Term Loan and of all fees and other amounts payable under any
Loan Document are payable without deduction for or on account of any present or
future taxes, levies, imposts, deductions, charges, fees, duties or
withholdings, and all liabilities with respect thereto, excluding in the case
of the Lender the following: (i) taxes imposed on such person's income, and
franchise taxes imposed on it, by the jurisdiction order which such person is
organized or any political subdivision thereof and, in the case of the Lender,
taxes imposed on its income, and franchise taxes imposed on it; (ii) income
taxes imposed by the United States of America; and (iii) any taxes imposed by
the United States of America by means of withholding at the source if and to
the extent that such taxes shall be in effect and shall be applicable, on the
date hereof, to payments to be made to the Lender (all such nonexcluded taxes,
levies, imposes, deductions, changes, fees, duties, withholdings and
liabilities being hereinafter referred to as "Taxes"). If any Borrower is
required by law to deduct any Taxes from or in respect of any sum payable
hereunder or under the Note to the Lender, the Borrowers shall pay additional
interest or shall make additional payments in such amounts so that every net
payment of principal of and interest on the affected Term Loan and of all other
amounts payable by it under any



                                      19
<PAGE>   26


Loan Document, after withholding or deduction for or on account of any such
Taxes will not be less than the amount provided for herein or therein.

                  (b) Borrowers agree to pay any present or future stamp or
documentary taxes or any other excise or property taxes, charges or similar
levies which arise from any payment made hereunder or under the Note or from
the execution, delivery or registration of, or otherwise with respect to, this
Agreement or the Note (the "Other Taxes").

                  (c) The Borrowers, to the fullest extent permitted by law,
will indemnify the Lender for the full amount of Taxes or Other Taxes
(including any Taxes or Other Taxes imposed by any jurisdiction on amounts
payable under this Section 3.3) paid by the Lender and any liability (including
penalties, interest and expenses) arising therefrom or with respect thereto
except as a result of the gross negligence or willful misconduct of the Lender,
whether or not such Taxes or Other Taxes were correctly or legally asserted.
This indemnification shall be made within 30 days from the date the Lender
makes written demand therefor.

                  (d) Within 30 days after the date of any payment of Taxes by
or at the discretion of the Borrowers, the Borrowers will furnish to the
Lender, at its address referred to herein, the original or a certified copy of
a receipt evidencing payment thereof. Should the Lender ever receive any
refund, credit or deduction from any taxing authority to which the Lender would
not be entitled but for the payment by the Borrowers of Taxes as required by
this Section 3.3 (it being understood that the decision as to whether or not to
claim, and if claimed, as to the amount of any such refund, credit or deduction
shall be made by the Lender in its sole discretion), the Lender thereupon shall
repay to the Borrowers an amount with respect to such refund, credit or
deduction equal to any net reduction in Taxes actually obtained by the Lender
and determined by the Lender to be attributable to such refund, credit or
deduction.

         Section 3.4 Computation of Interest. Interest on the Term Loan and all
other amounts payable by the Borrowers hereunder shall be computed on the basis
of a year of 360 days and the actual number of days elapsed (including the
first day but excluding the last day) unless such calculation would result in a
usurious rate, in which case interest shall be calculated on the basis of a
year of 365 or 366 days, as the case may be.

                                  ARTICLE IV

                        Yield Protection and Illegality

          Section 4.1 Increased Costs. The Borrowers shall, jointly and
severally, pay to the Lender from time to time, within 15 days following demand
by the Lender such additional amounts as the Lender may determine to be
necessary to compensate it for any increased costs incurred by it which it
determines are attributable to its making or maintaining of the Term Loan
hereunder or any reduction in any amount receivable by the Lender hereunder in
respect of the Term Loan or such obligation other than increased costs
described in Section 2.5 or in Section 4.2 (such increases in costs and
reductions in amounts receivable being herein called "Increased Costs"),
resulting from either (i) the introduction of or any change in or in the
interpretation of any law or regulation by any



                                      20
<PAGE>   27


Governmental Authority, central bank or comparable agency charged with the
interpretation or administration thereof, or (ii) the compliance with any
guideline or request from any Governmental Authority, central bank or
comparable agency (whether or not having the force of law).

         The Lender will furnish the Borrowers with a certificate, in
reasonable detail, setting forth the basis and the amount of such Increased
Costs of the Lender. The Borrowers shall reimburse the Lender for such
increased cost in accordance with this Section 4.1.

         Section 4.2 Capital Adequacy. If after the date hereof, the Lender
shall have determined that the adoption or implementation of any applicable
law, rule, or regulation regarding capital adequacy, or any change therein, or
any change in the interpretation or administration thereof by any central bank,
comparable agency, or other Governmental Authority charged with the
interpretation or administration thereof, or compliance by the Lender (or its
lending office or parent) with any guideline, request, or directive regarding
capital adequacy (whether or not having the force of law) of any central bank,
comparable agency, or other Governmental Authority (except to the extent such
request or directive arises as a result of the individual credit-worthiness of
the Lender), has the effect of increasing the amount of capital required or
expected to be maintained as a result of its Commitment hereunder, or has or
would have, the effect of reducing the rate of return on the Lender's (or its
parent's) capital as a consequence of its obligations hereunder or the
transactions contemplated hereby to a level below that which the Lender (or its
parent) could have achieved but for such adoption, implementation, change or
compliance (taking into consideration the Lender's policies with respect to
capital adequacy) by an amount deemed by the Lender to be material, then from
time to time, within 10 Business Days after demand by the Lender, the Borrowers
shall, jointly and severally, pay to the Lender such additional amount or
amounts as will compensate the Lender (or its parent) for such reduction. A
certificate of the Lender, in reasonable detail, claiming compensation under
this Section and setting forth the additional amount or amounts to be paid to
it hereunder shall be conclusive, absent manifest errors, although the failure
to give any such notice shall not diminish any of the Borrowers' obligations to
pay such additional amounts, and, the Borrowers shall, jointly and severally,
pay such additional amounts as provided herein. In determining such amount or
amounts, the Lender may use any reasonable averaging and attribution methods.

                                   ARTICLE V

cause to be executed such further documents and instruments, including without

reasonable discretion, deems necessary or desirable to evidence and perfect its

after the date hereof by any Borrower or any Subsidiary created or acquired

the Security Agreement and/or the addendum thereto with respect to the

Vessels ("Charters") to any such charter party from time to time in Lender's
sole discretion. In addition, the Borrowers shall include language in each such
Charter reasonably acceptable to the Lender that such Charter is assignable to
the Lender.

         Section 5.2 Setoff. If an Event of Default shall have occurred and is
continuing, the Lender is hereby authorized at any time and from time to time,
without notice to the Borrowers (any such notice being hereby expressly waived
by the Borrowers), to set off and apply any and all deposits (general or
special, time or demand, provisional or final) at any time held and other

account of the Borrowers against any and all of the obligations of any of the

<PAGE>   29


have made any demand under this Agreement or the Note or such other Loan
Document and although such obligations may be unmatured. The Lender agrees
promptly to notify the Borrowers after any such setoff and application,
provided that the failure to give such notice shall not affect the validity of
such setoff and application. The rights and remedies of the Lender hereunder
are in addition to other rights and remedies (including, without limitation,
other rights of setoff) which the Lender may have.

"Systems") used by Borrowers to carry on their businesses as presently

Compliant or will be Year 2000 Compliant within a period of time calculated to
result in no material disruption



                                      29
<PAGE>   36



of any of Borrowers' business operations. For purposes of these provisions,
"Year 2000 Compliant" means that such Systems are designed to be used prior to,
during and after the Gregorian calendar year 2000 A.D. and will operate during
each such time period without error relating to date data, specifically
including any error relating to, or the product of, date data which represents
or references different centuries or more than one century.

                  (b) Borrowers have: (1) undertaken a detailed inventory,
review, and assessment of all areas within their businesses and operations that

would, with reasonable probability, result in a material adverse change in the
business, properties, condition (financial or otherwise), or prospects of any
of the Borrowers.

each Subsidiary. All such policies are in full force and effect, all premiums
with respect thereto covering all periods up to and including the date of the
closing have been paid, and no notice of cancellation or termination has been
received with respect to any such policy. Such policies are sufficient for
compliance with all requirements of law and of all agreements to which the
Borrowers or any Subsidiary is a party; are valid, outstanding and enforceable
policies; provide adequate insurance coverage in at least such amounts and
against at least such risks (but including in any event public liability) as

limited below usual and customary policy limits, by an insurance carrier to
which it has applied for any such insurance or with which it has carried
insurance during the last three years.

will cause each Subsidiary to comply, in all material respects with all
agreements, contracts, and instruments binding on it or affecting its
properties or business.

         Section 8.10 Further Assurances. Each Borrower will, and will cause
each Subsidiary to, execute and deliver such further agreements and instruments

Borrowers in connection with the Notice and/or a Change in Circumstances.

regarding additional Subsidiaries), it shall grant or cause such Subsidiaries
to grant liens and security interests in favor of the Lender by the execution
of Loan Documents required by the Lender in form and substance satisfactory to
the Lender covering all of such newly acquired Properties.

         Section 8.14 Subsidiary Guaranties and Pledge of Assets. Within 30
days after the acquisition or formation of any Subsidiary of any of the
Borrowers, the Borrowers shall cause such new Subsidiary to execute and deliver

          Section 12.2 Indemnification. The Borrowers, jointly and severally,
shall indemnify the Lender and each Affiliate thereof and their respective
officers, directors, employees, attorneys, and agents from, and hold each of
them harmless against, any and all losses, liabilities, claims, damages,
penalties, judgments, disbursements, costs, and expenses (including attorneys'
fees) to which any of them may become subject which directly or indirectly
arise from or relate to (a) the negotiation, execution, delivery, performance,
administration, or enforcement of any of the Loan Documents, (b) any of the
transactions contemplated by the Loan Documents, (c) any breach by any Borrower
of any representation, warranty, covenant, or other agreement contained in any
of the Loan Documents, (d) the presence, Release, threatened Release, disposal,
removal, or cleanup of any Hazardous Material located on, about, within, or
affecting any of the properties or assets of any Borrower or any Subsidiary, or
(e) any investigation, litigation, or other proceeding, including, without
limitation, any threatened investigation, litigation, or other proceeding
relating to any of the foregoing. Without limiting any provision of this
Agreement or of any other Loan Document, it is the express intention of the
parties hereto that each Person to be indemnified under this Section shall be
indemnified from and held harmless against any and all losses, liabilities,
claims, damages, penalties, judgments, disbursements, costs, and expenses
(including attorneys' fees) arising out of or resulting from the sole or
contributory negligence of such Person.

          Section 12.3 Limitation of Liability. None of the Lender or any
Affiliate, officer, director, employee, attorney, or agent thereof shall have
any liability with respect to, and any Borrower hereby waives, releases, and
agrees not to sue any of them upon, any claim for any special, indirect,
incidental, or consequential damages suffered or incurred by any Borrower in
connection with, arising out of, or in any way related to, this Agreement or any
of the other Loan Documents, or any of the transactions contemplated by this
Agreement or any of the other Loan Documents, except for gross negligence or
willful misconduct in which event damages will be limited to actual damages.
Each Borrower hereby waives, releases, and agrees not to sue the Lender or any
of its Affiliates, officers, directors, employees, attorneys, or agents for
punitive damages in respect of any claim in connection with, arising out of, or
in any way related to, this Agreement or any of the other Loan Documents, or
any of the transactions contemplated by this Agreement or any of the other Loan
Documents.

          Section 12.4 No Duty. All attorneys, accountants, appraisers, and
other professional Persons and consultants retained by the Lender shall have
the right to act exclusively in the interest of the Lender and shall have no
duty of disclosure, duty of loyalty, duty of care, or other duty or obligation
of any type or nature whatsoever to any Borrower or any of the Borrowers'
shareholders or any other Person.

         Section 12.5 No Fiduciary Relationship. The relationship between each
Borrower and the Lender is solely that of debtor and creditor, and the Lender
has no fiduciary or other special relationship with any Borrower, and no term
or condition of any of the Loan Documents shall be construed so as to deem the
relationship between any Borrower and the Lender to be other than that of
debtor and creditor.

         Section 12.6 Equitable Relief. Each Borrower recognizes that in the
event any Borrower fails to pay, perform, observe, or discharge any or all of
the Obligations, any remedy at law may


                                       46
<PAGE>   53

prove to be inadequate relief to the Lender. Each Borrower therefore agrees
that the Lender, if the Lender so requests, shall be entitled to temporary and
permanent injunctive relief in any such case without the necessity of proving
actual damages.

         Section 12.7 No Waiver, Cumulative Remedies. No failure on the part of
the Lender to exercise and no delay in exercising, and no course of dealing
with respect to, any right, power, or privilege under this Agreement shall
operate as a waiver thereof, nor shall any single or partial exercise of any
right, power, or privilege under this Agreement preclude any other or further
exercise thereof or the exercise of any other right, power, or privilege. The
rights and remedies provided for in this Agreement and the other Loan Documents
are cumulative and not exclusive of any rights and remedies provided by law.

         Section 12.8 Successors and Assigns.

                  (a) This Agreement shall be binding upon and inure to the
benefit of the parties hereto and their respective successors and assigns. The
Borrowers may not assign or transfer any of their rights or obligations
hereunder without the prior written consent of the Lender. The Lender may sell
without notice to or consent of any Borrower participations to one or more
banks or other institutions in or to all or a portion of its rights and
obligations under this Agreement and the other Loan Documents (including,
without limitation, all or a portion of the Term Loan owing to it); provided,
however, that (i) the Lender's obligations under this Agreement and the other
Loan Documents shall remain unchanged, (ii) the Lender shall remain solely
responsible to the Borrowers for the performance of such obligations, (iii) the
Lender shall remain the holder of its Note for all purposes of this Agreement,
(iv) the Borrowers shall continue to deal solely and directly with the Lender
in connection with the Lender's rights and obligations under this Agreement and
the other Loan Documents, and (v) the Lender shall not sell a participation
that conveys to the participant the right to vote or give or withhold consents
under this Agreement or any other Loan Document, other than the right to vote
upon or consent to (A) any reduction of the principal amount of, or interest to
be paid on, the Term Loan of the Lender, (B) any reduction of any commitment
fee or other amount payable to the Lender under any Loan Document, or (C) any
postponement of any date for the payment of any amount payable in respect of
the Term Loan to the Lender.

                  (b) The Lender may, without notice to or consent of any
Borrower, sell, assign or transfer to any one or more persons or entities, all
or any part of the Term Loan or all or any part of the Loan Documents and each
such assignee or transferee shall have the right to enforce the Term Loan, and
such Loan documents as fully as the Lender, provided that the Lender shall
continue to have the unimpaired right to enforce the provisions of the Loan
Documents and the Term Loan that it has not sold, assigned or transferred.

                  (c) In connection with and prior to and after any such sale,
transfer, assignment or participation, the Lender may disclose and furnish to
any prospective or actual purchaser, transferee, assignee or participant, any
and all reports, financial statements and other information obtained by the
Lender at any time and from time to time in connection with the Term Loan, the
Loan Documents or otherwise. The Borrowers shall fully cooperate with the
Lender in connection with any such assignment and shall execute and deliver
such consents and acceptances to any such


                                      47
<PAGE>   54

assignment as the Lender shall reasonably request that are necessary or
desirable to effect any such assignment.

          Section 12.9 Survival. All representations and warranties made in
this agreement or any other Loan Document or in any document, statement, or
certificate furnished in connection with this Agreement shall survive the
execution and delivery of this Agreement and the other Loan Documents, and no
investigation by the Lender or any closing shall affect the representations and
warranties or the right of the Lender to rely upon them. Without prejudice to
the survival of any other obligation of the Borrowers hereunder, the
obligations of the Borrowers under Article IV and Sections 12.1 and 12.2 shall
survive repayment of the Note and termination of the Commitments.

          Section 12. 10 ENTIRE AGREEMENT. THIS AGREEMENT, THE NOTE, AND THE
OTHER LOAN DOCUMENTS REFERRED TO HEREIN EMBODY THE FINAL, ENTIRE AGREEMENT
AMONG THE PARTIES HERETO AND SUPERSEDE ANY AND ALL PRIOR COMMITMENTS,
AGREEMENTS, REPRESENTATIONS, AND UNDERSTANDINGS, WHETHER WRITTEN OR ORAL,
RELATING TO THE SUBJECT MATTER HEREOF AND MAY NOT BE CONTRADICTED OR VARIED BY
EVIDENCE OF PRIOR, CONTEMPORANEOUS, OR SUBSEQUENT ORAL AGREEMENTS OR
DISCUSSIONS OF THE PARTIES HERETO. THERE ARE NO ORAL AGREEMENTS AMONG THE
PARTIES HERETO.

          Section 12.11 Amendments, Etc. No amendment or waiver of any
provision of this Agreement, the Notes, or any other Loan Document to which any
Borrower is a party, nor any consent to any departure by any Borrower
therefrom, shall in any event be effective unless the same shall be agreed or
consented to by the Lender and the Borrowers, and each such waiver or consent
shall be effective only in the specific instance and for the specific purpose
for which given.

          Section 12.12 Maximum Interest Rate.

                  (a) The collateral covered in the Vessel Mortgage and the
Obligations covered by this Agreement, the Note and other Loan Documents is or
will be secured by a "Preferred Mortgage" on the United States-flagged Vessels
within the meaning of Section 31322 of 46 U.S.C. 131301-31343 (1994), as amended
(the "Ship Mortgage Act"), and the regulations promulgated thereunder. If, for
any reason, the provisions of Section 31322 of the Ship Mortgage Act shall be
found not to exempt any and all interest and other charges contracted for,
charged, taken, received or reserved in connection with the Obligations covered
by this Agreement, the Note, and other Loan Documents from any limitations
otherwise applicable, then the provisions of Section 12.12(b) shall apply, but
otherwise the provisions of Section 31322 of the Ship Mortgage Act shall be
applicable.

                  (b) No provision of this Agreement or of any other Loan
Document shall require the payment or the collection of interest in excess of
the maximum amount permitted by applicable law. If any excess of interest in
such respect is hereby provided for, or shall be adjudicated to be so provided,
in any Loan Document or otherwise in connection with this loan transaction, the
provisions of this Section shall govern and prevail and neither any of the
Borrowers nor the sureties, guarantors, successors, or assigns of any of the
Borrowers shall be obligated to pay the excess


                                      48

<PAGE>   55

amount of such interest or any other excess sum paid for the use, forbearance,
or detention of sums loaned pursuant hereto. In the event the Lender ever
receives, collects, or applies as interest any such sum, such amount which
would be in excess of the maximum amount permitted by applicable law shall be
applied as a payment and reduction of the principal of the indebtedness
evidenced by the Note; and, if the principal of the Note has been paid in full,
any remaining excess shall forthwith be paid to the Borrowers. In determining
whether or not the interest paid or payable exceeds the Maximum Rate, the
Borrowers and the Lender shall, to the extent permitted by applicable law, (a)
characterize any non-principal payment as an expense, fee, or premium rather
than as interest, (b) exclude voluntary prepayments and the effects thereof,
and (c) amortize, prorate, allocate, and spread in equal or unequal parts the
total amount of interest throughout the entire contemplated term of the
indebtedness evidenced by the Note so that interest for the entire term does
not exceed the Maximum Rate.

         Section 12.13 Notices. All notices and other communications provided
for in this Agreement and the other Loan Documents to which any Borrower is a
party shall be given or made by telex, telegraph, telecopy, cable, or in
writing and telexed, telecopied, telegraphed, cabled, mailed by certified mail
return receipt requested, or delivered to the intended recipient at the
"Address for Notices" specified below its name on the signature pages hereof;
or, as to any party at such other address as shall be designated by such party
in a notice to each other party given in accordance with this Section. Except
as otherwise provided in this Agreement, all such communications shall be
deemed to have been duly given when transmitted by telex or telecopy, subject
to telephone confirmation of receipt, or delivered to the telegraph or cable
office, subject to telephone confirmation of receipt, or when personally
delivered or, in the case of a mailed notice, when duly deposited in the mails,
in each case given or addressed as aforesaid; provided, however, notices to the
Lender pursuant to Article II shall not be effective until received by the
Lender.

         Section 12.14 LAW AND JURISDICTION.

                  THIS AGREEMENT AND THE LOAN DOCUMENTS PROVIDED FOR HEREIN
         (INCLUDING, BUT NOT LIMITED TO THE VALIDITY AND ENFORCEABILITY HEREOF
         AND THEREOF) SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH,
         THE LAWS OF THE STATE OF ILLINOIS, OTHER THAN CONFLICT OF LAWS THEREOF
         ANY LEGAL ACTION OR PROCEEDING AGAINST ANY OF THE BORROWERS WITH
         RESPECT TO THIS AGREEMENT OR ANY LOAN DOCUMENT MAY BE BROUGHT IN THE
         COURTS OF THE STATE OF ILLINOIS. THE U.S. FEDERAL COURTS IN SUCH
         STATE, SITTING IN THE COUNTY OF COOK, OR IN THE COURTS OF ANY OTHER
         JURISDICTION WHERE SUCH ACTION OR PROCEEDING MAY BE PROPERLY BROUGHT,
         AND THE BORROWERS HEREBY IRREVOCABLY ACCEPT THE JURISDICTION OF SUCH
         COURTS FOR THE PURPOSE OF ANY ACTION OR PROCEEDING. EACH OF THE
         BORROWERS DESIGNATES AND APPOINTS CT CORPORATION SYSTEM, 208 SOUTH
         LASALLE STREET, CHICAGO, ILLINOIS 60604 TO RECEIVE ON THEIR BEHALF,
         SERVICE OF ALL PROCESS IN ANY PROCEEDING IN ANY SUCH COURT, SUCH
         SERVICE BEING HEREBY ACKNOWLEDGED BY EACH CREDIT PARTY TO BE EFFECTING
         AND BINDING SERVICE IN EVERY RESPECT. A copy


                                      49
<PAGE>   56

         of such service of process shall be mailed by U.S. registered or
         certified mail postage prepaid to the party to be served at its
         address designated in Section 12.13 hereof except that unless
         otherwise required by law, any failure to mail such copy shall not
         affect the validity of service of process. The Borrowers agree that a
         final judgment in any action or proceeding shall be conclusive and may
         be enforced in any other jurisdiction by suit on the judgment or in
         any other manner provided by law. Nothing in this Section 12.14 shall
         affect the right of the Lender to serve legal process in any other
         manner permitted by law or affect the right of the Lender to bring any
         action or proceeding against any Borrower or its Properties in the
         courts of any other jurisdiction. To the extent that any Borrower has
         or hereafter may acquire any immunity from jurisdiction of any court
         or from any legal process (whether through service of notice,
         attachment prior to judgment, attachment in aid of execution,
         execution or otherwise) with respect to either itself or its Property,
         such Borrower hereby irrevocably waives such immunity in respect of
         its obligations under this Agreement and the other Loan Documents to
         the extent permitted by law. To the extent permitted by law each of
         the Borrowers hereby irrevocably waives any objection that it may now
         or hereafter have to the laying of venue of any suit, action or
         proceeding arising out of or relating to this Agreement or any loan
         Document brought in any state or federal court located within the
         County of Cook, State of Illinois, and hereby further irrevocably
         waives any claim that any such suit, action or proceeding brought in
         any such court has been brought in an inconvenient forum.

          Section 12.15 Counterparts. This Agreement may be executed in one or
more counterparts, each of which shall be deemed an original, but all of which
together shall constitute one and the same instrument.

          Section 12.16 Severability. Any provision of this Agreement held by a
court of competent jurisdiction to be invalid or unenforceable shall not impair
or invalidate the remainder of this Agreement and the effect thereof shall be
confined to the provision held to be invalid or illegal.

          Section 12.17 Headings. The headings, captions, and arrangements used
in this Agreement are for convenience only and shall not affect the
interpretation of this Agreement.

          Section 12.18 Non-Application of Chapter 346 of Texas Finance Code.
The provisions of Chapter 346 of the Texas Finance Code are specifically
declared by the parties hereto not to be applicable to this Agreement or any of
the other Loan Documents or to the transactions contemplated hereby.

          Section 12.19 Construction. The Borrowers and the Lender acknowledge
that each of them has had the benefit of legal counsel of its own choice and
has been afforded an opportunity to review this Agreement and the other Loan
Documents with its legal counsel and that this Agreement and the other Loan
Documents shall be construed as if jointly drafted by the parties hereto.

          Section 12.20 Independence of Covenants. All covenants hereunder
shall be given independent effect so that if a particular action or condition
is not permitted by any of such covenants, the fact that it would be permitted
by an exception to, or be otherwise within the


                                       50
<PAGE>   57

limitations of, another covenant shall not avoid the occurrence of a Default if
such action is taken or such condition exists.

          Section 12.21 JURY WAIVER. THE BORROWERS AND THE LENDER (BY THEIR
ACCEPTANCE HEREOF) HEREBY VOLUNTARILY, KNOWINGLY, IRREVOCABLY AND
UNCONDITIONALLY WAIVE ANY RIGHT TO HAVE A JURY PARTICIPATE IN RESOLVING ANY
DISPUTE (WHETHER BASED UPON CONTRACT, TORT OR OTHERWISE) BETWEEN OR AMONG ANY
BORROWER AND THE LENDER ARISING OUT OF OR IN ANY WAY RELATED TO THIS AGREEMENT,
ANY OF THE OTHER LOAN DOCUMENTS, OR ANY RELATIONSHIP BETWEEN THE LENDER AND ANY
BORROWER. THIS PROVISION IS A MATERIAL INDUCEMENT TO THE LENDER TO PROVIDE THE
FINANCING DESCRIBED HEREIN OR IN THE OTHER LOAN DOCUMENTS.

          Section 12.22 Confidentiality. In the event that any of the Borrowers
provides to the Lender written confidential information belonging to such
Borrower, if such Borrower shall denominate such information in writing as
"confidential", the Lender shall thereafter maintain such information in
confidence in accordance with the standards of care and diligence that it
utilizes in maintaining its own confidential information. This obligation of
confidence shall not apply to such portions of the information which (i) are in
the public domain, (ii) hereafter become part of the public domain without the
Lender breaching its obligation of confidence to such Borrower, (iii) are
previously known by the Lender from some source other than such Borrower, (iv)
are hereafter developed by the Lender without using the Borrower's information,
(v) are hereafter obtained by or made available to the Lender from a third
party who the Lender is not aware owes an obligation of confidence to such
Borrower with respect to such information or through any other means other than
through disclosure by such Borrower, (vi) are disclosed with such Borrower's
consent, (vii) must be disclosed either pursuant to any Governmental
Requirement or to Persons regulating the activities of the Lender, or (viii) as
may be required by law or regulation or order of any Governmental Authority in
any judicial, arbitration or governmental proceeding. Further, the Lender may
disclose any such information to Bank One, the Subordinated Lender, its
independent certified public accountants, and/or any legal counsel employed by
such Person in connection with this Agreement or any other Loan Document,
including without limitation, the enforcement or exercise of all rights and
remedies thereunder, or any assignee or participant (including prospective
assignees and participants) in the Term Loan; provided, however, that the
Lender shall receive a confidentiality agreement from the Person to whom such
information is disclosed such that said Person shall have the same obligation
to maintain the confidentiality of such information as is imposed upon the
Lender hereunder. Notwithstanding anything to the contrary provided herein,
this obligation of confidence shall cease three years from the date the
information was furnished, unless such Borrower requests in writing at least 30
days prior to the expiration of such three year period, to maintain the
confidentiality of such information for an additional three year period. Each
Borrower waives any and all other rights it may have to confidentiality as
against the lender arising by contract, agreement, statute or law except as
expressly stated in this Section 12.22.

reinforce the deck.

Reportedly, all internal and external anodes have recently been renewed.

Reportedly, all lower hull compartments have been cleaned and recoated with 
Texaco Compound H.

All machinery and equipment on the drydock appears to be in good condition and 
well coated.

This drydock, as described herein, is in satisfactory condition for its 
intended service.

This survey represents the good faith opinion of the surveyor only and does not 
make any representations of fact. It was performed for insurance underwriting 
and/or appraisal purposes only, and no warranty of correctness of this surveyor 
as to the condition, seaworthiness, value, or marketability of subject drydock 
is either expressed or implied.

The drydock was sighted afloat, without testing for tightness, hull gauging,
conducting sea trials, testing or trying out machinery or electrical systems, or
opening up any of those places ordinarily closed or concealed. Therefore,
deficiencies may exist other than those conditions noted in this report.

The undersigned Marine Surveyor has no present or contemplated future interest 
in the aforementioned drydock and/or its equipment, and compensation for 
services has been arranged for on an independent fee basis and is in no way

SURVEY REPORT NO. 9811-1212



                              SPUD BARGE "MM VII"

THIS IS TO CERTIFY that the undernamed attending Marine Surveyor did on 
November 30, 1998, at the request of Ms. Karen S. Shouse, and on behalf of and 
for the account of Bank One, Texas, NA, survey the undocumented steel Spud 
Barge "MM VII", an undocumented vessel of approximately 300 gross tons, 
previously assigned the official number 613041; reported owners Transcoastal 
Marine Services, Inc. - operators The Woodson Companies - while subject vessel 
lay afloat and moored in an unladened condition at the facilities of The 
Woodson Companies at Delcambre, Louisiana, in order to ascertain the general 
condition of the vessel and in order to estimate her present day fair market 
value and orderly liquidation values as of November 30, 1998.

Note: All sizes, measurements, distances, et cetera, mentioned herein are
      approximate, unless otherwise specified.

GENERAL CONSTRUCTION PARTICULARS:

The vessel was built of all welded steel construction. Date and circumstances 
of construction were unknown at time of survey. However, the vessel appears to 
be approximately 25 years old.

Overall dimensions are: Length - 120', breadth - 36', depth - 7'3".

This vessel is a typical inland deck cargo barge, converted for use as a spud 
barge and has a flush deck, a square raked bow, a square raked stern, one (1) 
bow rake compartment, four (4) main body hull compartments, and one (1) stern 
rake compartment.

The vessel is not fit with rub rail fenders.
<PAGE>   122
SURVEY REPORT NO. 9811-1212


GENERAL CONSTRUCTION PARTICULARS: (continued)

The vessel is not fit with skegs.

Access to each hull compartment is made via 24" diameter flush deck manhole 
with a center bolt cover.

Head log and stern log plating are estimated to be 3/4" original thickness. 
Rake knuckle plating is estimated to have been 1/2" original thickness. Bottom 
side and deck plating is estimated to have been 3/8" original thickness. 
Bulkheads are estimated to have been 5/16" original thickness. The vessel is 
framed longitudinally and stiffened transversely. Longitudinal deck beams are 5"
channel spaced on 18" centers. Longitudinal side frames are 4" channel spaced 
on 18" centers. Longitudinal bottom frames are 5" channel spaced on 22" 
centers. Bulk heads are stiffened vertically with 3" x 2 1/2" angle spaced on 
28" centers.

The vessel is stiffened transversely with transverse trusses spaced on 7 foot 
centers. All top, bottom and outboard cords are 8" channels. Trusses are 
additionally stiffened with 4" x 4" x 1/4" angle vertically spaced on 5 foot 
centers and two 4" x 3 1/2" x 1/4" angle diagonals in way of each truss.

The deck fittings consist of one (1) each, approximately 7" double bitts 
located on each corner, two (2) each approximately 30" kevels ranged on both 
port and starboard sides and one (1) each approximately 7" single bitts located 
near mid-length on both port and starboard side.

The vessel is fit with an approximately 6" high steel pollution barrier which 
extends around the entire peripheral of the vessel and is fit with drains with 
threaded plugs.

The vessel is fit with the remnants of a safety handrail system along both port 
and starboard sides.

The vessel is fit with one (1) each approximately 24" square internal spud 
wells located fore and aft on the starboard side. Each spud well is fit with 
fair lead sheaves to the spud winch which is located forward on the starboard 
side. The spud winch is a skid mounted double drum winch of unknown 
manufacturer driven by a General Motors 3 cylinder model 3-71 diesel engine 
through a power takeoff and a system of shafts and chains. The spud winch is
fit with a local control station and is complete with an approximately 30 
gallon fuel oil reserve tank and a 12 volt heavy duty marine battery.

The vessel is fit with two (2) each approximately 18" square by 40 foot long 
steel spuds [ILLEGIBLE] the spud wells.

The area over the spud winch is fit with an approximately 15' x 8' x 8' 
platform constructed of 4" diameter pipe stanchions and 4" H beam frames.
<PAGE>   123
SURVEY REPORT NO. 9811-1212

GENERAL CONSTRUCTION PARTICULARS: (continued)

The starboard number one main body compartment is fit with a steel access trunk 
with a weather tight steel door and stairs leading to the lower hull.

CERTIFICATES/DOCUMENTS:

No documents were on board the vessel at time of survey.

CONDITION:

The vessel was sighted afloat. Reportedly the vessel was last hauled out 
during April, 1990. The exterior coating of the vessel is good with only very 
occasional light rust patches. The interior of the vessels coating is fair and 
approximately 60% effective. Head log plating is heavily distorted on 
centerline and shows minor indents throughout. Rake bottom plating is devoid of 
major indents. Starboard side plating and rake knuckle set in 0 to 3" over an 
area of 8 feet by full depth of vessel in way of the bow double bits. Starboard 
side plating shows washboarding and is wavy 0 to 1" throughout with very 
occasional major indents of 0 to 2" at scattered locations. Stern log shows 
light scattered indents at random locations. Stern rake bottom plating is 
devoid of major indents. Port side plating is set in 0 to 3" over 12 feet by 
full depth of the vessel extending from the stern forward. Port side plating is 
set in 0 to 3" over an area of 12 feet by full depth of the vessel in way of 
the bow rake compartment. Remainder of the port side plating shows minor 
indents of 0 to 1" throughout and is lightly to moderately pitted and shows 
major wastage throughout.

The deck is heavily pitted and wasted throughout with areas of greater than 50% 
wastage obvious. The deck shows numerous minor indents due to thin plating. 
Bulkheads are obvious. Frames are obvious. Many longitudinal deck beams are 
crushed in way of the trusses. The entire deck in way of the stern rake 
compartment is set down from 0 to 3" with internals heavily distorted to 
conform. The spud wells appear nearly new and in satisfactory condition. The 
winch and winch engine appear in satisfactory condition. The stern double 
bitts are set inboard in way of the deck distortion. The pollution barrier is 
open at scattered locations. The safety hand rails on port and starboard sides 
are incomplete. The winch engine was not test operated at time of survey.

                                   LITIGATION


Sirpi Alusteel Construction, Ltd. v. Dickson GMP International

This case involves a contractual dispute in which Dickson has filed a cross
claim that if successful would eliminate any damages alleged by Sirpi and in
addition would result in a monetary judgement in favor of Dickson. We have been 
told by counsel for Dickson that maximum exposure in this case is approximately 
$95,000.00 (NINETY-FIVE THOUSAND AND NO/00 DOLLARS).

Dr. Abdo Husseiny, et al v. United Gas Pipeline Company, et al.

This is a class action lawsuit filed in 1994 as a result of a gas leak in St.
John the Baptist Parish in Louisiana. Approximately 7858 plaintiffs have joined
the class and are seeking damages ranging from $500.00 to $2500.00 each. The
liability portion of the case was tried to the bench. The court found Woodson
75% at fault and assessed punitive damages on a one to one ratio. Punitive
damages are uninsured. The case was appealed to the Fifth Circuit Court of
Appeals and writs were denied. We are currently negotiating with our underwriter
to approach the plaintiff with a settlement offer in which the entire case
(including punitives) would be settled within policy limits with Woodson
offering a cash contribution to the settlement. Such cash contribution would not
have a material impact on the operations of the Company. If we do not reach a
settlement, this case would begin trial in March of 1999. For the court to hear
all 7858 cases, trial could potentially extend for three to seven years.
