     (c)  On November 3, 1992, Portal, Pentad and Petrol entered into
substantially similar binding agreements in principle with the Issuer (the
"Agreements in Principle") pursuant to which the Issuer has agreed to cause one
or more wholly-owned subsidiaries (the "Subsidiary") to purchase certain assets
of Portal, Pentad and Petrol in exchange for cash, promissory notes and the
shares of Stock reported herein (the "Transaction").  BH was an additional
signatory to each Agreement in Principle in his individual capacity.  The
following description of the Agreements in Principle and the Transaction is not,
and does not purport to be, complete and is qualified in its entirety by
reference to the Agreements in Principle, which [were filed previously] as
Exhibits B, C, and D.

     Pursuant to the Agreements in Principle, the Issuer has agreed to purchase
the assets of Portal, Pentad and Petrol relating to their respective offshore
service and utility vessel businesses (the "Assets").    As consideration for
the Assets, the Issuer will pay to Portal, Pentad and Petrol an aggregate
purchase price of $18,500,000, consisting of (1) cash in the amount of
$2,750,000 (plus an additional $2,000,000 to be escrowed against necessary
repairs on certain of the Assets), (2) promissory notes in the aggregate amount
of $5,250,000 and (3) that number of shares of the Stock obtained by dividing
$8,500,000 by the average closing sale price of the Stock quoted on the NASDAQ
National Market System for the 35 trading days immediately preceding the closing
date (the "Market Price").  For the purposes of the initial filing, the
Reporting Persons [assumed] a Market Price of $6.00, which [was] the closing
sale price of the Stock quoted on the NASDAQ National Market System on November
3, 1992.

     Consummation of the Transaction is conditioned upon, among other things,
(1) the execution and delivery of definitive agreements between the Issuer and
the Subsidiary, on the one hand, and Portal, Pentad and Petrol, on the other
hand, containing customary representations and warranties, (2) satisfactory
results of due diligence investigations, (3) no material adverse change in the
Assets or in the Issuer, (4) the execution and delivery of non-competition
agreements between the Issuer and the Subsidiary, on the one hand, and the
Reporting Persons and David Hunt, on the other hand, (5) the receipt of all
necessary consents and approvals, (6) the Issuer's guarantee of the Subsidiary's
obligations with respect to the Transaction, (7) the Issuer's Board of
Directors' having increased the number of its members by one and having elected
BH to fill such vacancy until the next annual meeting of stockholders, and (8)
certain Issuer affiliates' having delivered voting agreements pursuant to which
they shall agree to vote for the election of BH or his designee as a director
of the Issuer at the 1993 annual meeting of stockholders.

     In the Agreements in Principle, Portal, Pentad, Petrol and BH have agreed
that they will not, and that they will cause their respective officers,
directors, stockholders and affiliates not to, (1) until the closing of the
Transaction, offer to acquire, acquire, offer to sell or sell, directly or
indirectly, any voting securities of the Issuer and (2) after the closing of the
Transaction and without the consent of the Issuer's Board of Directors, acquire
or offer to acquire, directly or indirectly, any voting securities of the Issuer
if, as a result, they would collectively own in excess of 15% of the then-
outstanding voting securities of the Issuer.

     The Agreements in Principle provide for Portal, Pentad and Petrol to
deliver to the Issuer their voting agreements pursuant to which they shall agree
to vote their shares of Stock for the election of Larry Hornbeck as a director
of the Issuer and for the election of L. E. Simmons or another person designated
in substitution for him as a director of the Issuer.

     The Agreements in Principle also provide for registration rights and
related repurchase offer options in favor of the Issuer with respect to the
shares of the Stock to be issued in the Transaction to the extent specified in
such Agreements in Principle.

     The Reporting Persons anticipate the closing of the Transaction to occur
on or about November 19, 1992.

     AS AMENDED IN ITS ENTIRETY BY AMENDMENT NO. 1 DATED NOVEMBER 23, 1992:

     On November 16, 1992 Portal, Pentad and Petrol entered into substantially
similar Asset Purchase Agreements (the "Asset Purchase Agreements"), as
contemplated by the Agreements in Principle, and closed the Transaction pursuant
to such Asset Purchase Agreements and related agreements as of November 19,
1992.  The following description of the Asset Purchase Agreements, certain of
the related agreements and the Transaction is not, and does not purport to be,
complete and is qualified in its entirety by reference to Exhibits E through Q
[previously filed as exhibits] hereto.

     Pursuant to the Asset Purchase Agreements and at the closing of the
Transaction (the "Closing"), the Issuer caused certain of its wholly-owned
subsidiaries (the "Subsidiaries") to purchase the Assets from Portal, Pentad and
Petrol for an aggregate purchase price of $18,500,000, consisting of (1) cash
in the amount of $2,750,000 (plus an additional $2,000,000 escrowed against
necessary repairs to certain of the Assets), (2) promissory notes in the
aggregate amount of $5,250,000 and (3) 1,365,462 shares of the Stock, which
number was obtained by dividing $8,500,000 by $6.225, which was the average
closing sale price of the Stock quoted on the NASDAQ National Market System for
the 35 trading days immediately preceding the closing date.

     At the Closing, the Issuer also delivered promissory notes to Portal,
Pentad and Petrol in the respective amounts of $2,540,390, $2,525,169 and
$184,441, a form of which promissory notes [was previously filed] as Exhibit I
(the "Notes").  The Notes provide for quarterly payments of principal and
interest (amortized over seven years) for five years, with balloon payments due
at maturity.  The Notes bear interest at the prime rate of Citibank, N.A., plus
one percent, and provide for standard events of default.  Pursuant to the terms
of the Asset Purchase Agreements, the Notes may be transferred only to certain
persons and entities related to Portal, Pentad and Petrol, and are subject to
certain offset rights.  Also, pursuant to the Agency Agreement, a copy of which 
was previously filed as Exhibit J, the Issuer is entitled to make payments under
the Notes and otherwise to deal concerning the Notes solely with BH as agent for
all holders of the Notes.  Pursuant to the Limited Guaranty Agreements, a copy
of the form of which was previously filed as Exhibit K, the Subsidiaries
severally have unconditionally guaranteed payment of the Notes by the Issuer to
the extent of the relative proportions of the Assets respectively purchased by
them in the Transaction.

     Also at the Closing, certain Issuer affiliates and Portal, Pentad and
Petrol entered into a Voting Agreement, a copy of the form of which [was
previously filed] as Exhibit M, pursuant to which such Issuer affiliates
generally have agreed to vote for the election of BH or his designee as a
director of the Issuer and Portal, Pentad and Petrol have agreed to vote their
shares of Stock for the election of Larry Hornbeck as a director of the Issuer
and for the election of L. E. Simmons or another person designated in
substitution for him as a director of the Issuer.  The Voting Agreement expires
on the earlier of (a) the tenth anniversary thereof and (b) the date upon which
the Reporting Persons and certain persons and entities related to them (the
"Hunt Group") cease to own in the aggregate at least 5% of the shares of
outstanding Stock.  As a condition to the Closing, the Issuer's Board of
Directors increased its size to eight and appointed BH to fill such vacancy
until the 1993 annual meeting of stockholders.

     Pursuant to the Stockholders Agreement, a copy of the form of which [was
previously filed] as Exhibit L, entered into at the Closing, Portal, Pentad,
Petrol and BH have agreed that they will not, and that they will cause their
respective officers, directors, stockholders and affiliates not to, without the
consent of the Issuer's Board of Directors, acquire or offer to acquire,
directly or indirectly, any voting securities of the Issuer if, as a result,
they would collectively own in excess of 15% of the then-outstanding voting
securities of the Issuer.

     The Stockholders Agreement further obligates the Hunt Group generally to
provide the Issuer with 5 days' written notice of a decision by any Hunt Group
member (a) to sell to one person shares of Stock representing 5% or more of the
outstanding shares of the Stock (a "Block Sale"), (b) to consider accepting an
unsolicited offer to make a Block Sale, or (c) to request an investment banker
or broker to locate a purchaser for a Block Sale, in each case other than as
permitted by the volume and holding restrictions of Rule 144 under the
Securities Act of 1933, as amended (the "Securities Act").  Following such
notice, the Stockholders Agreement obligates the Hunt Group to meet with the
[Issuer] concerning the event and to allow the [Issuer] the opportunity to make
or sponsor a competing offer.

     Also pursuant to the Stockholders Agreement, the Issuer has granted
registration rights as described below to holders of the shares of Stock issued
in the Transaction (collectively, the "Registrable Securities").  Upon receipt
of a written request at any time after December 31, 1993, and on or prior to
February 14, 1994 (the "First Demand"), from the holders of at least 51% of the
Registrable Securities, the Issuer either (1) will file a registration statement
with the Securities and Exchange Commission to register under the Securities Act
all of the eligible Registrable Securities requested to be included in the
registration, subject to such pro rata reduction, if any, that the underwriters
of the offering may recommend, but in any event not to exceed 300,000 shares in
the aggregate, or (2) will purchase the number of shares of the Stock requested
to be registered (not to exceed 300,000) from such persons at a per share price
equal to 90% of the Market Price, as defined therein.  At any time after
December 31, 1995, and on or prior to February 14, 1996, holders of Registrable
Securities may make a second demand on the [Issuer] for registration on the
identical terms and conditions that were applicable to the First Demand.

     If at any time the Issuer proposes to file a registration statement under
the Securities Act registering securities to be sold with respect to the Stock
or any other class of equity security, the Stockholders Agreement requires the
Issuer to give written notice to the holders of Registrable Securities and to
include in such filing the number of shares of Registrable Securities for which
such holders request registration, subject to such pro rata reduction, if any,
that the underwriters of the offering may recommend, and subject to the rights
of other holders of securities of the Issuer to whom the Issuer has previously
granted registration rights.  The holders of Registrable Securities will not
have such incidental registration rights with respect to any registration by the
Issuer (d) pursuant to a stock option or other employee incentive compensation
plan or stockholder reinvestment plan, (e) with respect to securities issued in
a business combination with, or purchase of any securities or assets of, a third
party, or (f) with respect to securities issued in connection with any anti-
takeover plan.  There is no limit on the number of incidental registrations
permitted.

     Holders of Registrable Securities generally will pay all expenses of any
such requested or incidental registration.

THE END THEREOF THE FOLLOWING:

     Effective March 18, 1994, the Issuer prepaid all remaining amounts due
under the Notes and, in connection therewith, the Issuer entered into a
substantially similar (i) Amendment No. 1 to Asset Purchase Agreement (the
"Purchase Agreement Amendment"), (ii) Amendment No. 1 to Stockholders Agreement
(the "Stockholders Agreement Amendment") and (iii) Pledge Agreement (the "Pledge
Agreement"), with each of Portal, Pentad and Petrol.  BH in his individual
capacity also was a party to the Stockholders Agreement Amendment.  Also
effective March 18, 1994, and in connection with the resolution of various
disputes between the Issuer, on the one hand, and Portal and Pentad, on the
other hand, with respect to charges for the refurbishment of certain of the
Assets (the "Refurbishment Program"), the Issuer and each of Portal and Pentad
entered into a Mutual Release.  The following description of the Purchase
Agreement Amendments, the Stockholder[s] Agreement Amendments, the Pledge

     Pursuant to the Purchase Agreement Amendments, Section 10.5 of each Asset
Purchase Agreement was amended to provide for the pledging of shares of the
Stock pursuant to the Pledge Agreement to secure the indemnification obligations
of Portal, Pentad and Petrol under their respective Asset Purchase Agreements
(the "Indemnification Obligations") in lieu of the Issuer's offset rights under
the Notes extinguished by the prepayment of the Notes.

     Pursuant to the Pledge Agreements, Portal, Pentad and Petrol pledged
114,740 shares, 34,427 shares and 15,616 shares of the Stock, respectively, to
secure their respective Indemnification Obligations.  Upon an Event of Default,
as defined in each Pledge Agreement, the Issuer is entitled to transfer the
pledged shares of the Stock into its own name and to apply the Fair Market Value
thereof to pay the Secured Obligations, as both of such terms are defined in
each Pledge Agreement.

     Each Pledge Agreement terminates on the later of (i) November 27, 1994 and
(ii) the date that an indemnification claim made in accordance with Article 10
of the applicable Asset Purchase Agreement is reduced to a resolved claim, as
defined therein.

     The Stockholders Agreement Amendment (a) changes the First Demand period
to any time after December 31, 1994 and on or prior to February 15, 1995 and (b)
provides that, in the event of a 1995 Demand Registration or a 1996 Demand
Registration, as defined in the Stockholders Agreement Amendment, the Issuer
shall be obligated to effect a shelf registration only and shall not be required
to participate or cooperate in an underwritten offering.

     Pursuant to the Mutual Releases, each of the Issuer, on the one hand, and
Portal and Pentad, on the other hand, agrees to release the other from all
liability in connection with the Refurbishment Program.

by such Reporting Person.

     (e) 

     It is inapplicable for the purposes herein to state the date on which the
Reporting Persons ceased to be the owners of more than five (5) percent of the
outstanding shares of the Stock.

Item 6.  CONTRACTS, ARRANGEMENTS, UNDERSTANDINGS OR RELATIONSHIPS
         WITH RESPECT TO SECURITIES OF THE ISSUER.

     Except as set forth herein or in the Exhibits filed or to be filed
