ITEM 2.  ACQUISITION OR DISPOSITION OF ASSETS.

         On December 10, 1996, Energy Ventures, Inc., a Delaware corporation
(the "Company"), completed the acquisition (the "Arrow Acquisition") of the
operating assets of Arrow Completion Systems, Inc., a Texas corporation
("Arrow"), from Weatherford Enterra, Inc., a Delaware corporation, pursuant to
a Stock Purchase Agreement dated as of October 18, 1996 (the "Arrow
Agreement").  Under the terms of the Arrow Agreement, the Company paid
consideration of approximately $21.3 million cash and assumed certain
liabilities of Arrow.  The cash consideration paid in the Arrow Acquisition was
funded with a portion of the proceeds from the Company's recent sale of its
Mallard Bay drilling rig division to Parker Drilling Company.  The principle
followed in fixing the purchase price for Arrow under the Arrow Agreement was
based on negotiations between the parties.

         Arrow is a manufacturer and distributor of downhole packers and oil
recovery and completion service tools.  The Company currently intends to
integrate the operations of Arrow with those of its oil tools division and to
offer Arrow's product line and services in conjunction with the Company's own
line of oilfield equipment, tools and services.

         A copy of the press release announcing the closing of the Arrow
Agreement is filed as Exhibit 99.1 and is hereby incorporated herein by
reference.


ITEM 5.  OTHER EVENTS.

         On December 5, 1996, the Company entered into an Agreement and Plan of
Merger (the "Merger Agreement") with GulfMark Acquisition Co., a Delaware
corporation and wholly owned subsidiary of the Company, GulfMark International,
Inc., a Delaware corporation ("GulfMark"), and New GulfMark International,
Inc., a Delaware corporation and wholly owned subsidiary of GulfMark ("New
GulfMark"), providing for the acquisition by the Company of GulfMark pursuant
to a tax free merger (the "Merger") in which approximately 2.2 million shares
of the Company's common stock, $1.00 par value (the "Common Stock"), will be
issued to the stockholders of GulfMark.

         Prior to the Merger, GulfMark will contribute its marine
transportation services business to New GulfMark and will then spin-off to its
stockholders the stock of New GulfMark.  Following the spin-off, the remaining
assets of GulfMark will consist of approximately 2.2 million shares of the
Company's Common Stock, GulfMark's erosion control business and certain
corporate and miscellaneous assets.  It is anticipated that GulfMark will have
no material debt as of the consummation of the Merger.  The acquisition of
GulfMark is expected to increase the Company's stockholder base while allowing
it to acquire a profitable low cost business with potential synergies with the
Company's businesses at an attractive price.





                                    Page 2

         The Merger is subject to various conditions, including the receipt of
all required regulatory approvals and the expiration or termination of all
waiting periods (and extensions thereof) under the Hart-Scott-Rodino Act.
Although there can be no assurance that the Merger will close, the Company
currently anticipates that the acquisition will be consummated shortly after
the receipt of such regulatory approvals and the approval of the Merger by the
stockholders of the Company and GulfMark.

         A copy of the press release announcing the signing of the Merger
Agreement is filed as Exhibit 99.2 and is hereby incorporated herein by
reference.


ITEM 7.   FINANCIAL STATEMENTS AND EXHIBITS

         (a)     Financial Statements of Business Acquired.

         The Company is currently in the process of obtaining financial
statements with respect to Arrow. The financial statements of Arrow required, 
if any, for this item are not currently available and will be filed, if
required, by the Company by an amendment to this report as soon as practical,
but not later than 60 days after this report must be filed.
        

         (b)     Pro Forma Financial Information.

         The Arrow Acquisition will be accounted for as a purchase and will
require an allocation of the purchase price among the acquired assets.  As of
the date of this report, such allocation has not been completed and it would be
impracticable for the Company to provide the pro forma financial information
required, if any, pursuant to Article 11 of Regulation S-X with respect to the
Arrow Acquisition.  Such pro forma financial information will be filed, if
required, by the Company by an amendment to this report as soon as practical,
but not later than 60 days after this report must be filed.

                                  contracts and engagements to which the Seller
                                  is entitled on the Closing Date and which
                                  relate to the Business (the "Entitlements");

                          (viii)  all prepaid expenses and deposits made by the

                  (b)     The Seller shall use its best efforts to obtain such
consents of third parties as are necessary for the assignment of the
Transferred Assets.  To the extent that any of the Transferred Assets are not
assignable by the terms thereof or consents to the assignment thereof cannot be
obtained as provided herein, the Transferred Assets shall be held by the Seller
in trust for the Buyer and shall be performed by the Buyer in the name of the
Seller and all benefits and obligations derived thereunder shall be for the
account of the Buyer; provided, however, that where entitlement of the Buyer to
such Transferred Assets hereunder is not recognized by any third party, the
Seller shall, at the request of the Buyer, enforce in a reasonable manner, at
the cost of and for the account of the Buyer, any and all rights of the Seller
against such third party.

                  (c)     The Seller shall also notify each Person that may
have possession of the Transferred Assets at the Closing Date, whether by
consignment or otherwise, of the transfer of such Transferred Assets to the

         1.2      Excluded Assets.  Anything in Section 1.1(a) to the contrary
notwithstanding, there shall be excluded from the assets, properties, rights
and business





                                      -2-

to be transferred to the Buyer hereunder those assets of the Seller listed or
described in Section 1.2 of the Disclosure Schedule (collectively, the
"Excluded Assets").

         1.3      Purchase Price for the Assets.

                  (a)     In consideration of the transfer to the Buyer of the
Transferred Assets, the Buyer shall (i) pay to the Seller an amount in cash
equal to the Cash Purchase Price and (ii) assume (A) the payment obligations of
the Seller with respect to all Trade Payables, Accrued Liabilities and Notes
Payable as of the Closing Date and (B) the obligations of the Seller under the
express written terms of the Entitlements to the extent and only to the extent
such obligations are not Pre-Closing Obligations (collectively, the "Assumed
Liabilities").  The Cash Purchase Price and the Assumed Liabilities are herein
collectively referred to as the "Purchase Price".

                  (b)     On the Closing Date, the Buyer shall pay to the
Seller by wire transfer of same day funds of $21,307,000 (the "Closing
Payment").  The Closing Payment shall be based on the balance sheet of the
Seller, at September 30, 1996, a copy of which has been provided to the Buyer
(the "Pre-Closing Balance Sheet").  The Buyer shall be entitled to review the
accounting records used to prepare the Pre-Closing Balance Sheet and confirm
the existence of the assets and liabilities reflected thereon prior to the
Closing.

         1.4      Purchase Price Adjustment.

                  (a)     Within 60 calendar days after the Closing Date, the
Buyer shall prepare and deliver to the Seller a statement reflecting the Cash
Purchase Price and the calculation thereof (the "Final Statement").  The Buyer
shall provide the Seller with access to copies of all work papers and other
relevant documents to verify the entries contained in the Final Statement.  The
Seller shall have a period of 15 calendar days after delivery to it of the
Final Statement to review it and make any objections the Seller may have in
writing to the Buyer.  If written objections to the Final Statement are
delivered to the Buyer within such 15 day period, then the Buyer and the Seller
shall attempt to resolve the matter or matters in dispute.  If no written
objections are made within the time period provided above, the Buyer shall pay
to the Seller in same day funds the aggregate amount, if any, by which the Cash
Purchase Price exceeds the Closing Payment and the Seller shall pay to the
Buyer in same day funds the aggregate amount, if any, by which the Closing
Payment exceeds the Cash Purchase Price, in each case within five calendar days
after the end of such 15 day period.

                  (b)     If disputes with respect to the Final Statement
cannot be resolved by the Buyer and the Seller within 15 calendar days after
the delivery of the objections to the Final Statement, then the specific
matters in dispute shall be submitted to Arthur Andersen LLP or such other
independent accounting firm as may be approved by the Buyer and the Seller,
which firm shall render its opinion as to such matters.  Based on such opinion,
such independent accounting firm will then send to the Buyer and the Seller its
determination on the specific matters in dispute, which determination shall be
final and binding on the parties hereto.  Within five calendar days after
delivery of such opinion to the Buyer and the Seller, the Buyer shall pay to
the Seller

obligations set forth in clauses (a) through (d) below (collectively, the

whether or not such transactions are consummated;

                  (b)     any liability or obligation for any and all Taxes of,
or pertaining or attributable to, (i) the Seller for any period that ends on or
before the Closing Date, or (ii) the Business and/or the Transferred Assets for
any period or portion thereof that ends on or before the Closing Date
(including, but in no way limited to, any and all Taxes described in clauses

jurisdiction; and

                  (d)     all other liabilities and obligations of any Person

                  (a)     The Seller warrants that the Transferred Assets are

<PAGE>   9
prorated between the Buyer and the Seller as of the Closing Date.  In the event
the amount of any such general property Tax cannot be ascertained as of the
Closing Date, proration shall be made on the basis of the preceding year, the
Buyer shall receive a credit against the Cash Purchase Price on the Closing
Date for the Seller's pro rata portion of such general property Taxes, and to
the extent that such proration may be inaccurate the Seller and the Buyer agree

and other items of expense attributable to the conduct of the Business shall be
prorated as of the Closing Date to the extent the charges and expenses cannot
be identified as to the party that received the benefits to which such charges
and expenses relate.  To the extent such amounts are estimated on the Closing
Date and such prorations are inaccurate, the Seller and the Buyer agree to make
such payment to the other after such amounts are correctly computed as is
necessary to allocate such charges properly between the Seller and the Buyer as
of the Closing Date.

imposed as a result of the consummation of the transactions contemplated by
this Agreement.

                  (b)     The Buyer shall pay any and all recording, filing or
other fees relating to the conveyance or transfer of the Transferred Assets
from the Seller to the Buyer.

Date a certificate certifying that the Inventories are being purchased for
resale to the extent stated therein.

         1.8      Allocation of Purchase Price.  The Purchase Price shall be
allocated among the Transferred Assets by the Buyer and the Seller within 60

basis of any act, statement, agreement or commitment alleged to have been made
by the Seller, Weatherford or any Affiliate of Weatherford with respect to any
fee, commission or expense payable to Merrill Lynch, Simmons or any other party
with respect to the sale by the Seller of any of the Transferred Assets or with
respect to the transactions contemplated by this Agreement.

                                   ARTICLE 4

                             ADDITIONAL AGREEMENTS

         4.1      Delivery of Corporate Documents; Proprietary Data; Record
Retention; Financial Statements.

                  (a)     The Seller shall deliver to the Buyer all Documents
and Other Papers relating to the Transferred Assets, the Assumed Liabilities
and the current and proposed operations of the Business, including, without
limitation, all files relating to the Accounts Receivable and the Trade
Payables, computer disks reflecting any books or records, documents or other
papers, or other information or data relating to the operation of the Business
or the Transferred Assets stored on any electronic media, including computers.
The Seller, however, shall be entitled to retain the historical books and
records relating to the Business to the extent such books and records are not
necessary for the ongoing operations of the Business by the Buyer.

                  (b)     The Seller and Weatherford agree that neither of them
nor any of their Affiliates shall retain any copies of any blueprints,
drawings, diagrams, models or similar Proprietary Information included in the
Transferred Assets.

                  (c)     In the event and for so long as any party is
contesting or defending against any action, suit, proceeding, hearing,
investigation, charge, complaint, claim or demand asserted by a third party
(including any Governmental Entity) in connection with (i) any transaction
contemplated by this Agreement or (ii) any fact, situation, circumstance,
status, condition, activity, practice, plan, occurrence, event, incident,
action, failure to act or transaction on or prior to the Closing Date involving
the Business or the Transferred Assets, the other party will to the extent
reasonably practicable cooperate with the contesting or defending party and its
counsel in the contest or defense, and provide such testimony and access to its
books and records as shall be necessary in connection with the contest or
defense, all at the sole cost and expense of the contesting or defending party
(except to the extent the contesting or defending party is entitled to
indemnification therefor under Article 8 hereof); provided, however, that
nothing herein requires any party to retain any books and records other than in
the ordinary course of business; provided further, any party hereto, before
destroying any historical books and records that relate in whole or in part to
the Business or the Transferred Assets, shall give such other party reasonable
notice of its intention to destroy such books and records and an opportunity to
make copies thereof at the sole expense of the party destroying such copies.
In addition, the Buyer agrees to provide Weatherford with reasonable access to
any books and records included in the Transferred Assets as may be necessary
for the preparation of any Tax returns or financial statements.
Notwithstanding the foregoing, information as to which the contesting or
defending party may reasonably assert would waive a privilege need not be
disclosed.

                  (d)     If the Buyer is required under applicable United
States federal securities laws to include historical accounting information for
periods prior to the Closing relating to the Business in any of the Buyer's
filings with the Securities and





                                      -15-
<PAGE>   20
Exchange Commission, then the Seller shall cooperate with and provide the Buyer
reasonable access, during regular business hours and upon reasonable advance
notice, to the Seller's accounting records relating to the Business prior to
the Closing and shall cause its outside auditors to cooperate, at the Buyer's
expense, with the Buyer in the preparation of such historical financial
statements relating to the Business prior to the Closing as may be required
under such securities laws to be included in such filings.

         4.2      Further Assurances.  The Seller shall execute, acknowledge
and deliver or cause to be executed, acknowledged and delivered to the Buyer
such bills of sale, assignments (including, but not limited to, assignments of
leases) and other instruments of transfer, assignment and conveyance, in form
and substance satisfactory to counsel for the Buyer, as shall be necessary to
vest in the Buyer all the right, title and interest in and to the Transferred
Assets free and clear of all Liens (including the release of all Liens of
record) and shall use its best efforts to cause to be taken such other action
as the Buyer reasonably may require to more effectively implement and carry
into effect the transactions contemplated by this Agreement.

         4.3      Nondisclosure of Proprietary Information.

                  (a)     The Seller agrees that, from and after the Closing
Date, the Seller and its Affiliates shall:

                          (i)     hold in confidence and will not directly or
                  indirectly at any time reveal, report, publish, disclose or
                  transfer to any Person other than the Buyer any of the
                  Proprietary Information that is not generally known to the
                  public or utilize any of the Proprietary Information for any
                  purpose; and

                          (ii)    not for a period of two years solicit any 
                  Transferred Employees.

                  (b)     The Seller acknowledges that all documents and
objects containing or reflecting any Proprietary Information, whether developed
by the Seller or by someone else for the Seller or any of its Affiliates, will
after the Closing Date become the exclusive property of the Buyer and be
delivered to the Buyer.

                  (c)     Because of the unique nature of the Proprietary
Information, the Seller understands and agrees that the breach or anticipated
breach of the obligations under this Section 4.3 will result in immediate and
irreparable harm and injury to the Buyer and its Affiliates, for which it will
not have an adequate remedy at law, and that the Buyer and its Affiliates and
their successors and assigns shall be entitled to relief in equity to enjoin
such breach or anticipated breach and to seek any and all other legal and
equitable remedies to which they may be entitled.

         4.4      Covenant Not to Compete With the Business.  As an inducement
to the Buyer to acquire the Business, each of Weatherford and the Seller agree
that, except as otherwise permitted herein or Exhibit A hereto, effective as of
the Closing Date and for a period of three years thereafter, it and its
Affiliates shall not, without the consent





                                      -16-
<PAGE>   21
of the Buyer, directly or indirectly, engage in the manufacture of packer
equipment.  Weatherford and the Seller acknowledge that a remedy at law for any
breach or attempted breach of this Section 4.4 will be inadequate and further
agrees that any breach of this Section 4.4 will result in irreparable harm to
the Business and the Buyer shall, in addition to any other remedy that may be
available to it, be entitled to specific performance and injunctive and other
equitable relief in case of any such breach or attempted breach.  Weatherford
and the Seller acknowledge that this covenant not to compete is being provided
as an inducement to the Buyer to acquire the Business and the Transferred
Assets and that this Section 4.4 contains reasonable limitations as to time,
geographical area and scope of activity to be restrained that do not impose a
greater restraint than is necessary to protect the goodwill or other business
interest of the Buyer.  Whenever possible, each provision of this Section 4.4
shall be interpreted in such a manner as to be effective and valid under
applicable law, but if any provision of this Section 4.4 shall be prohibited by
or invalid under applicable law, such provision shall be ineffective to the
extent of such prohibition or invalidity, without invalidating the remaining
provisions of this Section 4.4.  If any provision of this Section 4.4 shall,
for any reason, be judged by any court of competent jurisdiction to be invalid
or unenforceable, such judgment shall not affect, impair or invalidate the
remainder of this Section 4.4 but shall be confined in its operation to the
provision of this Section 4.4 directly involved in the controversy in which
such judgment shall have been rendered.  In the event that the provisions of
this Section 4.4 should ever be deemed to exceed the time or geographic
limitations permitted by applicable laws, then such provision shall be reformed
to the maximum time or geographic limitations permitted by applicable law.  The
foregoing provisions of this Section 4.4 shall not prevent Weatherford or any
of its Affiliates from making any acquisition (whether by way of assets, stock
or otherwise) of, or retain any interest in, or any investment in, in either
case, whether directly or indirectly, any business, entity or affiliated group
of entities that on a consolidated basis during the most recent fiscal quarter
derived 20% or less of its gross revenues from the manufacture and sale of
packer equipment so long as (i) such acquisition is pursuant to an agreement
entered into on or after one year from the Closing Date or (ii) the business or
entities that are engaged in the manufacture and sale of packer equipment is
sold within one year after the date of acquisition of such business or
entities.  In addition, the foregoing provision shall not prohibit Weatherford
or any of its Affiliates from making any acquisition (whether by way of assets,
stock or otherwise) or any investment in, in either case, whether directly or
indirectly, any business, entity or affiliated group of entities that are
engaged in the business of the manufacture and sale of packer equipment as long
as the agreement to make such acquisition is entered into after two years from
the Closing Date.  The foregoing provisions shall also not prohibit any Person
who may in the future acquire 50% or more of the outstanding capital stock of
Weatherford (or any successor thereto) from engaging in the manufacture of
packer equipment as long as such acquiring Person was engaged in the
manufacture of packer equipment prior to such acquisition.

         4.5      Employee Matters.

                  (a)     The Buyer agrees to offer employment to all of the
employees of the Seller or EPEG who are engaged in the Business on terms
substantially similar to those under which such employees are currently
engaged, provided that the Buyer need only





                                      -17-
<PAGE>   22
offer the Seller's employees those benefits that are provided by the Buyer to
similarly situated employees.  Any such employees that the Buyer in fact
employs immediately after the Closing Date shall hereinafter be referred to as
the "Transferred Employees."  Any such employees who are not employed by the
Buyer or one of its Affiliates immediately after the Closing Date shall
hereinafter be referred to as the "Terminated Employees."  In determining
eligibility for and entitlement to vacation and other normal benefits
(excluding stock-based plans and incentive programs) based on length of service
by Transferred Employees under the Buyer's normal policies, service with the
Seller or EPEG shall be considered by the Buyer and its Affiliates as service
with the Buyer and its Affiliates.

                  (b)     The Seller shall be responsible for the severance
obligations, if any, with respect to the Terminated Employees.  The Buyer
agrees that if the employment of any of the Transferred Employees with the
Buyer or its Affiliates is terminated by the Buyer within six months following
the Closing Date other than for cause, the Buyer will provide to such
terminated Transferred Employee the severance that such Transferred Employee
would have received had the Transferred Employee been entitled to receive
severance from the Seller in accordance with the severance policy (including,
as applicable, the Weatherford Enterra Special Severance Payment Plan) of the
Seller previously provided to the Buyer, without giving effect to any
provisions that eliminate the severance payment obligations as a result of a
purchaser of the Business offering the Transferred Employee employment.

                  (c)     In determining eligibility for and the amount of
severance benefits the Transferred Employees may become entitled to upon
termination of employment with the Buyer or one of its Affiliates after the
Closing Date under the Buyer's normal severance policies, service with the
Seller or EPEG shall be considered as service with the Buyer and its
Affiliates.

                  (d)     The parties hereto do not intend to create any
third-party beneficiary rights respecting any employee of the Seller as a
result of the provisions hereof and specifically hereby negate any such
intention.

                  (e)     The Buyer agrees to provide to all Transferred
Employees the opportunity to participate in group health and other benefit
plans maintained by it or its Affiliates for similarly situated employees.  The
Buyer agrees to use its best efforts to obtain group health coverage for the
Transferred Employees effective as of the Closing Date; provided, however, such
coverage need not cover pre-existing conditions.  With respect to any
Transferred Employees with pre-existing conditions, the Buyer, at its option,
will either make coverage available to such Transferred Employees (by waiving
any waiting periods for such pre-existing conditions) or, for a period of 12
months, reimburse such Transferred Employees for the premiums paid by such
employees (who elect to retain their existing coverage) to maintain their prior
coverage with the Seller as permitted under applicable law.

                  (f)     The Buyer shall be fully responsible for all
liabilities related to the termination by the Buyer of the employment of any of
the Transferred Employees within 90 days after the Closing Date or such other
period that would expose the Seller





                                      -18-
<PAGE>   23
to liabilities under the WARN Act as a result of the premature termination by
the Buyer of the employment of any of the Transferred Employees.

         4.6      Use of Corporate Names.  All uses of the corporate names set
forth in Section 1.1(a)(vi) of the Disclosure Schedule, or any derivations
thereof, are being transferred to the Buyer hereunder as part of the
Transferred Assets.  The Seller agrees that it will not take any action that
could reasonably be expected to adversely affect the Buyer's right to the such
names or cause confusion with respect to the Buyer's use of the such names.
All goodwill with respect to the use of the names will inure to the benefit of
the Buyer, and the Seller will not have any rights to sue or recover against
any person with respect to the use of such names.


                                   ARTICLE 5

proceeding or investigation before any Governmental Entity shall have been
commenced or threatened by any Person (other than the Buyer or any of its
Affiliates) seeking to prevent the sale of the Transferred Assets or the
Business or asserting that the sale of all or a portion of the Transferred
Assets or the Business would be unlawful.

business, operations and assets to be; or

                  (e)     the Buyer or the Seller (provided the terminating

controlling Persons and their respective successors and assigns harmless from
and against and in respect of Damages actually





                                      -22-
<PAGE>   27
suffered, incurred or realized by such party (collectively, "Buyer Losses"),
arising out of or resulting from or relating to:

                  (a)     any misrepresentation, breach of warranty (other than
a misrepresentation or breach of any of the representations set forth in
Section 2.8) or breach of any covenant or agreement made or undertaken by the
Seller in this Agreement or any misrepresentation in or omission from any other
agreement, certificate, exhibit or writing delivered to the Buyer pursuant to
this Agreement, including the Disclosure Schedule;

                  (b)     any Retained Liability;

                  (c)     any liability resulting from the acquisition in
August 1996 by EPEG of the common stock of Watson Packer owned by stockholders
other than EPEG and matters relating thereto;

                  (d)     any products manufactured, sold or distributed or
services provided by or on behalf of the Seller on or prior to the Closing Date
or with respect to any claims made pursuant to warranties to third Persons in
connection with products manufactured, sold or distributed or services provided
by or on behalf of the Seller on or prior to the Closing Date; or

                  (e)     any and all Environmental Liabilities that may be
imposed upon or incurred by the Buyer or its respective officers, directors,
employees, agents, stockholders and controlling Persons or their respective
successors and assigns, arising out of or in connection with (i) the acts or
omissions of any Person prior to the Closing Date relating to the Seller, any

Assets, the operations currently or previously conducted by the Seller or its
Affiliates on any other assets or properties currently or previously leased or

representation or warranty contained in Section 2.8; (iii) any and all
Environmental Conditions existing on or prior to the Closing Date on, at or
underlying the Real Property or the Leasehold Interests; or (iv) the handling,
storage, treatment or disposal of any Hazardous Materials generated by Seller
on or prior to the Closing Date (collectively, "Environmental Losses").

Notwithstanding the foregoing, neither Weatherford nor the Seller shall be
liable under clause (a) of this Section 8.1 in respect of a misrepresentation
or breach of warranty unless and until the aggregate amount of any Buyer Losses
for which the Buyer is entitled to indemnification pursuant to such clause from
all such Persons exceeds $500,000 and then only for those Buyer Losses that in
the aggregate exceed $500,000; provided, however, (i) liability under clauses
(b) through (e) of this Section 8.1 shall not be so limited, (ii) liability
under clause (a) of this Section 8.1 shall not be so limited if such Buyer
Losses arise from a breach of any of the representations set forth in Sections

Losses that arise from a breach of any of the representations set forth in
Sections 2.2, 2.4 or





                                      -23-
<PAGE>   28
2.12, which shall not be limited, liability under clause (a) of this Section
8.1 shall not exceed the Cash Purchase Price.

         8.2      Indemnification by the Buyer.  Except as otherwise limited by
this Article 8 and Article 9 hereof, the Buyer agrees to indemnify, defend and
hold the Seller, Weatherford and each of its officers, directors, employees,
agents, stockholders and controlling Persons and its successors and assigns
harmless from and against and in respect of Damages actually suffered, incurred
or realized by such party (collectively, "Seller Losses"), arising out of or
resulting from:

                  (a)     any misrepresentation, breach of warranty or breach
of any covenant or agreement made or undertaken by the Buyer in this Agreement
or any misrepresentation in or omission from any other agreement, certificate,
exhibit or writing delivered to the Seller or Weatherford pursuant to this
Agreement; or

                  (b)     any Assumed Liability.

         8.3      Special Environmental Remediation.

                  (a)     In addition to the indemnification provided in
Section 8.1 hereof, Weatherford agrees to commence as promptly as reasonably
practicable any remediation at the Seller's Huntsville facility that the
investigation currently being conducted by the Seller demonstrates is required
by Environmental Law to achieve at least Risk Reduction Standard No. 2 under
the Texas Natural Resource Conservation Commission ("TNRCC") regulations
(subject to the provisions set forth in Section 8.3(b)), and to diligently
pursue the remediation until it is completed (the "Huntsville Remediation").
Weatherford further agrees to perform the actions described in Exhibit B and to
pay for the capital expenditures described in Exhibit B.  The remediation and
capital expenditures described in Exhibit B are herein referred to as the
"Watson Remediation" and collectively with the Huntsville Remediation as the
"Remediation".  The Remediation shall be effected in compliance with all
applicable federal, state and local safety and health laws and applicable
Environmental Laws.  Prior to the Closing, Weatherford and the Buyer will
review the cost estimates for the "Recommended Facility Upgrades" set forth in
the Watson Packer, Inc. Environmental Site Assessment (Project # WEA 99-1011)
dated July 1996 prepared by Nickell Environmental Corporation (the "Watson
Phase II").  If Weatherford and the Buyer agree in writing that the cost
estimates represent an acceptable payment for the listed facility upgrades,
Weatherford will pay the Buyer at Closing the total estimated cost of such
facility upgrades, as set forth in the Watson Phase II, and the Buyer shall
assume responsibility for making the listed facility upgrades and will release
Weatherford, the Seller and their Affiliates from any and all responsibility
for such facility upgrades.  If Weatherford and the Buyer do not so agree,
Weatherford shall be obligated to make and pay for the upgrades as provided
herein.

                  (b)     The Buyer agrees to provide Weatherford and its
representatives with access to and cooperation with respect to the records,
employees, agents, assets and facilities to be acquired from the Seller
throughout the course of completion of the Remediation and any investigation,
clean-up, remediation or response, if any, pertaining





                                      -24-
<PAGE>   29
to any claims for indemnification made pursuant to Section 8.1(e) hereof.  The
Buyer further agrees that Weatherford shall have management and control over
the Remediation and over any proceeding, clean-up, remediation or any response
to or any negotiations or discussions with any governmental agencies or third
Persons (provided the Buyer shall have the right to participate in any such
negotiations or discussions) that could reasonably be expected to result in a
claim for an Environmental Loss pursuant to Section 8.1(e).  Subject to the
provisions of this Section 8.3 and Exhibit B, Weatherford shall have the right
to select the appropriate remedy to be implemented with respect to the
Remediation and in response to any claim for remediation or clean-up and the
right to control any other action with respect to an Environmental Loss for
which indemnification is required; provided that the remedy selected is in
compliance with applicable Environmental Laws and is adequate to comply with
the regulatory requirements of the TNRCC.  Further, the remedy will be adequate
to achieve closure under either Risk Reduction Standard 1 or Risk Reduction
Standard 2 for industrial facilities, as set forth in the regulations
promulgated by the TNRCC, unless the Buyer consents in writing to closure under
Risk Reduction Standard 3, which consent will not be unreasonably withheld, and
all costs of any continuing requirements imposed as a condition to the closure
shall be paid by Weatherford.  Weatherford shall effect any remedy in a manner
that will not unduly disrupt the Business.  Further, such remedies shall be
effected by Weatherford as promptly as reasonably practical under the
circumstances.  The Buyer agrees that, at the request of the Seller, the Buyer
will deed record any property owned by the Buyer that is remediated in
compliance with Risk Reduction Standard 2 or, with the consent of the Buyer,
Risk Reduction Standard 3.

         8.4      Procedure.  All claims for indemnification under this Article
8 shall be asserted and resolved as follows:

                  (a)     An Indemnitee shall promptly give the Indemnitor
notice of any matter that an Indemnitee has determined has given or could give
rise to a right of indemnification under this Agreement, stating the amount of
the Losses, if known, and method of computation thereof, all with reasonable
particularity, and stating with particularity the nature of such matter.
Failure to provide such notice shall not affect the right of the Indemnitee to
indemnification except to the extent such failure shall have resulted in
liability to the Indemnitor that could have been actually avoided had such
notice been provided within such required time period.

                  (b)     The obligations and liabilities of an Indemnitor
under this Article 8 with respect to Losses arising from claims of any third
party that are subject to the indemnification provided for in this Article 8
("Third Party Claims") shall be governed by and contingent upon the following
additional terms and conditions: if an Indemnitee shall receive notice of any
Third Party Claim, the Indemnitee shall give the Indemnitor prompt notice of
such Third Party Claim and the Indemnitor may, at its option, assume and
control the defense of such Third Party Claim at the Indemnitor's expense and
through counsel of the Indemnitor's choice reasonably acceptable to the
Indemnitee.  In the event the Indemnitor assumes the defense against any such
Third Party Claim as provided above, the Indemnitee shall have the right to
participate at its own expense in the defense of such asserted liability, shall
cooperate with the Indemnitor in such





                                      -25-
<PAGE>   30
defense and will attempt to make available on a reasonable basis to the
Indemnitor all witnesses, pertinent records, materials and information in its
possession or under its control relating thereto as is reasonably required by
the Indemnitor.  In the event the Indemnitor does not elect to conduct the
defense against any such Third Party Claim, the Indemnitor shall pay all
reasonable costs and expenses of such defense as incurred and shall cooperate
with the Indemnitee (and be entitled to participate) in such defense and
attempt to make available to it on a reasonable basis all such witnesses,
records, materials and information in its possession or under its control
relating thereto as is reasonably required by the Indemnitee.  Except for the
settlement of a Third Party Claim that involves the payment of money only and
for which the Indemnitee is totally indemnified by the Indemnitor, no Third
Party Claim may be settled without the written consent of the Indemnitee.

                  (c)     Notwithstanding the other procedural provisions of
this Section 8.4, with respect to any claims involving an environmental matter,
the following shall apply.  If in the good faith judgment of the Buyer, the
Buyer believes the circumstances underlying such claim creates an obligation to
report such matter to any Governmental Entity, the Buyer will first notify the
Seller of such belief.  As soon as practicable, but in no event more than 10
days after receiving the Buyer's notice, the Seller will contact such
Governmental Entities as the Buyer requests based on the Buyer's good faith
belief or shall inform the Buyer, in writing, of the basis for its belief that
no reporting is required.  If the Seller does not contact such Governmental
Entities within such period, the Buyer may do so.  With respect to any
Environmental Loss for which the Buyer may be entitled to indemnification, the
Seller shall have the right to perform and complete all actions required by the
Governmental Entities.  The Buyer shall have the right to attend meetings and
otherwise participate in all meetings and communications with the Governmental
Entities, and the Seller will give the Buyer reasonable advance notice and an
opportunity to so participate.  The Buyer may obtain information regarding the
status of any such matter directly from the applicable Governmental Entities,
but will give the Seller at least five Business Days' notice of the Buyer's
intent to meet or otherwise communicate therewith and the Seller shall have the
right to attend or participate in any meeting or communication, but the
Seller's failure to participate shall not affect the Buyer's right to proceed
with any such meeting or communication.  The Seller shall be deemed to have
satisfied in full its indemnity obligations with respect to any such matter if
it fully  complies with the remediation or other program prescribed or approved
by the appropriate Governmental Entity; provided, in no event shall the
foregoing be construed to relieve the Seller of any indemnity obligations
hereunder relating to the same matter to the extent additional governmental
requirements are imposed or Third Party Claims are asserted notwithstanding the
Seller's compliance with such governmental standards and in no event shall the
Buyer Indemnified Parties be precluded by the foregoing from asserting
indemnity rights for diminution in value of the property affected if the
property, after being remediated, cannot be used in the same manner as it was
used on the Closing Date.  The Buyer's indemnity rights shall not be adversely
affected if any of the Buyer's non-management employees contact any
Governmental Entity without approval from any management level employee.
Moreover, all other parties (including the Buyer's lenders and insurance
carriers) may have full access and may contact any Governmental Entity at their
own discretion without affecting the indemnity rights set





                                      -26-
<PAGE>   31
forth elsewhere in this Article 8; provided, however, in no event shall the
foregoing constitute authorization from the Seller for such third parties to
obtain documents or information from any Governmental Entity that is not public
information.  Notwithstanding anything to the contrary in this subsection,
neither the Buyer nor its Affiliates shall be required to comply with the
foregoing restrictions to the extent compliance with the foregoing would
violate laws or applicable regulations, would create an immediate endangerment
to health of persons or would materially impair the operations of the property
so affected by the matter.

         8.5      Payment.  Payment of any amounts due pursuant to this Article
8 shall be made within ten Business Days after notice is sent by the
Indemnitee.

         8.6      Failure to Pay Indemnification.  If and to the extent the
Indemnitee shall make written demand upon the Indemnitor for indemnification
pursuant to this Article 8 and the Indemnitor shall refuse or fail to pay in
full within ten Business Days of such written demand the amounts demanded
pursuant hereto and in accordance herewith, then the Indemnitee may utilize any
legal or equitable remedy to collect from the Indemnitor the amount of its
Losses.  Nothing contained herein is intended to limit or constrain the
Indemnitee's rights against the Indemnitor for indemnity, the remedies herein
being cumulative and in addition to all other rights and remedies of the
Indemnitee.

         8.7      Adjustment of Liability.  The amount which an Indemnitee
shall be entitled to receive from an Indemnitor with respect to any
indemnifiable Losses under this Article 8 shall be net of any insurance
recovery by the Indemnitee on account of such Losses from an unaffiliated
party.

         8.8      EXPRESS NEGLIGENCE.  THE FOREGOING INDEMNITIES SET FORTH
IN THIS ARTICLE 8 ARE INTENDED TO BE ENFORCEABLE AGAINST THE PARTIES IN
ACCORDANCE WITH THE EXPRESS TERMS AND SCOPE THEREOF NOTWITHSTANDING TEXAS'
EXPRESS NEGLIGENCE RULE OR ANY SIMILAR DIRECTIVE THAT WOULD PROHIBIT OR
OTHERWISE LIMIT INDEMNITIES BECAUSE OF THE SIMPLE OR GROSS NEGLIGENCE (WHETHER
SOLE, CONCURRENT, ACTIVE OR PASSIVE) OR OTHER FAULT OR STRICT LIABILITY OF ANY
OF THE INDEMNIFIED PARTIES.


                                   ARTICLE 9

                NATURE OF STATEMENTS AND SURVIVAL OF COVENANTS,
                   REPRESENTATIONS,WARRANTIES AND AGREEMENTS

         All statements of fact contained in any written statement (including
financial statements), certificate, instrument or document delivered by or on
behalf of the Seller pursuant to this Agreement shall be deemed representations
and warranties of the Seller.  The several representations and warranties of
the parties to this Agreement shall survive the Closing Date and shall remain
in full force and effect for a period of one year following the Closing Date
(except that the representations and warranties set





                                      -27-
<PAGE>   32
forth in Sections 2.2, 2.4 and 2.12 shall survive the Closing Date without
limitation) (the period during which the representations and warranties shall
survive being referred to herein with respect to such representations and
warranties as the "Survival Period"), and shall be effective with respect to
any inaccuracy therein or breach thereof (and a claim for indemnification under
Article 8 hereof may be made thereon) if a written notice asserting the claim
shall have been duly given in accordance with Article 8 hereof within the
Survival Period with respect to such matter.  All covenants and agreements
contained herein shall survive without limitation.  Any claim for
indemnification made during the Survival Period shall be valid and the
representations and warranties relating thereto shall remain in effect for
purposes of such indemnification notwithstanding such claim may not be resolved
within the Survival Period.  All representations, warranties and covenants and
agreements made by the parties shall not be affected by any investigation
heretofore or hereafter made by and on behalf of any of them and shall not be
deemed merged into any instruments or agreements delivered in connection with
this Agreement or otherwise in connection with the transactions contemplated
hereby.

                          AGREEMENT AND PLAN OF MERGER

         This Agreement and Plan of Merger, dated as of the 5th day of
December, 1996 (this "Agreement"), is among ENERGY VENTURES, INC., a Delaware
corporation ("EVI"), GULFMARK ACQUISITION CO., a Delaware corporation and
wholly-owned subsidiary of EVI ("Sub"), GULFMARK INTERNATIONAL, INC., a
Delaware corporation ("GulfMark"), and NEW GULFMARK INTERNATIONAL, INC., a
Delaware corporation and wholly-owned subsidiary of GulfMark ("Spinco").

         WHEREAS, subject to and in accordance with the terms and conditions of
this Agreement, the respective Boards of Directors of EVI, Sub and GulfMark,
and EVI as sole stockholder of Sub, have approved the merger of Sub with and
into GulfMark (the "Merger"), whereby each issued and outstanding share of
common stock, par value $1.00 per share, of GulfMark ("GulfMark Common Stock")
not owned directly or indirectly by GulfMark will be converted into the right
to receive .6695 of one share of common stock, par value $1.00 per share, of
EVI ("EVI Common Stock"); and

         WHEREAS, as a condition to the Merger, GulfMark will contribute to
Spinco (a) all of the stock of GulfMark's subsidiaries other than Ercon (the
"Marine Subsidiaries") and (b) the general corporate assets of GulfMark
(excluding (i) all EVI Common Stock held by GulfMark, (ii) any and all
property, assets, claims and rights, tangible and intangible of Ercon, as
defined herein, (iii) the original tax, accounting and other corporate records
of GulfMark and (iv) all of the shares of common stock and other ownership
interests held by GulfMark in American Independent Oil Company ("AIOC"), such
excluded assets being referred to herein as the "Excluded Assets") (the
"Assets") and Spinco will assume certain liabilities associated with the
Assets, the Marine Subsidiaries and GulfMark (the "Contribution") pursuant to
an Agreement and Plan of Distribution between GulfMark, Spinco and EVI in
substantially the form attached hereto as Exhibit A (the "Distribution
Agreement");

         WHEREAS, as a condition to the Merger, GulfMark will distribute to its
stockholders prior to the Merger all of the outstanding stock of Spinco (the
"Distribution");

         WHEREAS, for federal income tax purposes, it is intended that the
Merger shall qualify as a reorganization within the meaning of Section
368(a)(1)(B) of the Internal Revenue Code of 1986, as amended (the "Code"), and
the Contribution and Distribution qualify as transactions within the meaning of
Sections 368(a)(1)(D) and 355 of the Code; and

         WHEREAS, the parties hereto desire to set forth certain
representations, warranties and covenants made by each to the other as an
inducement to the consummation of the Merger;

         NOW, THEREFORE, in consideration of the premises and of the mutual
representations, warranties and covenants herein contained, the parties hereto
hereby agree as follows:
<PAGE>   6
                                   ARTICLE I

                                   THE MERGER

         1.1     THE MERGER.  Subject to and in accordance with the terms and
conditions of this Agreement and in accordance with the General Corporation Law
of the State of Delaware ("DGCL"), at the Effective Time (as defined in Section
1.3), Sub shall be merged with and into GulfMark.  As a result of the Merger,
the separate corporate existence of Sub shall cease and GulfMark shall continue
as the surviving corporation (sometimes referred to herein as the "Surviving
Corporation"), and all the properties, rights, privileges, powers and
franchises of Sub and GulfMark shall vest in the Surviving Corporation, without
any transfer or assignment having occurred, and certain liabilities, debts and
duties of Sub and GulfMark shall attach to the Surviving Corporation, all in
accordance with the DGCL and subject to the provisions of the Distribution
Agreement.

         1.2     CLOSING DATE.  The closing of the transactions contemplated by
this Agreement (the "Closing") shall take place at the offices of Fulbright &
Jaworski L.L.P, Houston, Texas, as soon as practicable after the satisfaction
or waiver of the conditions set forth in Article VI or at such other time and
place and on such other date as EVI and GulfMark shall agree; provided that the
closing conditions set forth in Article VI shall have been satisfied or waived
at or prior to such time.  The date on which the Closing occurs is herein
referred to as the "Closing Date".

         1.3     CONSUMMATION OF THE MERGER.  As soon as practicable on the
Closing Date, the parties hereto will cause the Merger to be consummated by
filing with the Secretary of State of Delaware a certificate of merger in such
form as required by, and executed in accordance with, the relevant provisions
of the DGCL.  The "Effective Time" of the Merger, as that term is used in this
Agreement, shall mean such time as a certificate of merger is duly filed with
the Delaware Secretary of State or at such later time (not to exceed 90 days
from the date the Certificate is filed) as is specified in the certificate of
merger pursuant to the mutual agreement of EVI and GulfMark.

         1.4     EFFECTS OF THE MERGER.  The Merger shall have the effects set
forth in the applicable provisions of the DGCL.  If at any time after the
Effective Time of the Merger, the Surviving Corporation shall consider or be
advised that any further assignments or assurances in law or otherwise are
necessary or desirable to vest, perfect or confirm, of record or otherwise, in
the Surviving Corporation, all rights, title and interests in all real estate
and other property and all privileges, powers and franchises of GulfMark and
Sub, the Surviving Corporation and its proper officers and directors, in the
name and on behalf of GulfMark and Sub, shall execute and deliver all such
proper deeds, assignments and assurances in law and do all things necessary and
proper to vest, perfect or confirm title to such property or rights in the
Surviving Corporation and otherwise to carry out the purpose of this Agreement,
and the proper officers and directors of the Surviving Corporation are fully
authorized in the name of GulfMark or otherwise to take any and all such
action.

         1.5     CERTIFICATE OF INCORPORATION; BYLAWS.  The Certificate of
Incorporation of GulfMark, as amended by the amendment set forth in Exhibit B
attached hereto, shall be the





                                       2
<PAGE>   7
Certificate of Incorporation of the Surviving Corporation and thereafter shall
continue to be its Certificate of Incorporation until amended as provided
therein or under the DGCL. The bylaws of Sub, as in effect immediately prior to
the Effective Time, shall be the bylaws of the Surviving Corporation and
thereafter shall continue to be its bylaws until amended as provided therein or
under the DGCL.

         1.6     DIRECTORS AND OFFICERS.  The directors of Sub immediately
prior to the Effective Time shall be the directors of the Surviving Corporation
at and after the Effective Time, each to hold office in accordance with the
Certificate of Incorporation and bylaws of the Surviving Corporation, and the
officers of Sub immediately prior to the Effective Time shall be the officers
of the Surviving Corporation at and after the Effective Time, in each case
until the earlier of their resignation or removal or their respective
successors are duly elected or appointed and qualified.

         1.7     CONVERSION OF SECURITIES.  Subject to the terms and conditions
of this Agreement, at the Effective Time, by virtue of the Merger and without
any action on the part of EVI, GulfMark, Sub or their stockholders:

                 (a)      Subject to adjustment pursuant to Section 1.7(e)
         hereof, each share of GulfMark Common Stock issued and outstanding
         immediately prior to the Effective Time (the "Shares"), shall be
         converted into the right to receive .6695 of a share of EVI Common
         Stock (the "Exchange Ratio"); provided, however, that no fractional
         shares of EVI Common Stock shall be issued and in lieu thereof, a cash
         payment shall be made in accordance with Section 1.7(d) hereof.
         Except as set forth in the preceding sentence with respect to cash in
         lieu of fractional shares, no other consideration will be paid to
         GulfMark or its stockholders.

                 (b)      Each Share owned directly or indirectly by GulfMark
         as treasury stock and each Share owned by Sub, EVI or any direct or
         indirect wholly-owned subsidiary of EVI or of GulfMark immediately
         prior to the Effective Time shall be canceled and extinguished without
         any conversion thereof and no payment shall be made with respect
         thereto.

                 (c)      Each share of common stock, par value $1.00 per
         share, of Sub issued and outstanding immediately prior to the
         Effective Time shall be converted into one fully paid and
         nonassessable share of common stock, $1.00 par value per share, of the
         Surviving Corporation.

                 (d)      No fractional shares of EVI Common Stock shall be
         issued in the Merger.  All fractional shares of EVI Common Stock that
         a holder of Shares would otherwise be entitled to receive as a result
         of the Merger shall be aggregated and if a fractional share of EVI
         Common Stock results from such aggregation (i) such fractional share
         of EVI Common Stock shall be disregarded and the shares of EVI Common
         Stock issuable to such holder shall be rounded off to the nearest
         whole share of EVI Common Stock if such fractional share of EVI Common
         Stock represents less than one-half of one percent of the total shares
         of EVI Common Stock such holder is entitled to receive in the Merger
         and (ii) in all other cases, such holder shall be entitled to receive,
         in lieu of a fractional





                                       3
<PAGE>   8
         share of EVI Common Stock, an amount in cash determined by multiplying
         the average of the daily closing sale price per share of EVI Common
         Stock on the New York Stock Exchange ("NYSE") for the ten trading days
         immediately preceding the Effective Time of the Merger by the fraction
         of a share of EVI Common Stock to which such holder would otherwise
         have been entitled.  No such cash in lieu of fractional shares of EVI
         Common Stock shall be paid to any holder of fractional shares of EVI
         Common Stock until Certificates (as defined in Section 1.8(c))
         representing such shares of EVI Common Stock are surrendered and
         exchanged in accordance with Section 1.8(c).  The total amount of cash
         to be received by the stockholders of GulfMark in lieu of fractional
         shares of EVI Common Stock will not exceed one percent of the total
         fair market value of the EVI Common Stock (as of the date on which the
         Effective Time occurs) to be issued in the Merger.

The Exchange Ratio is based on (i) 3,338,852 shares of GulfMark Common Stock
being issued and outstanding immediately prior to the Effective Time.  In the
event the number of shares of GulfMark Common Stock outstanding immediately
prior to the Effective Time is greater or less than 3,338,852, or the number of
shares of EVI Common Stock held by GulfMark is greater or less than 2,235,572,
the Exchange Ratio shall be adjusted to equal the number of shares of EVI
Common Stock held by GulfMark immediately prior to the Effective Time divided
by the number of shares of GulfMark Common Stock issued and outstanding
immediately prior to the Effective Time.

         1.8     EXCHANGE OF CERTIFICATES.

                 (a)      Exchange Agent.  Prior to the Effective Time of the
         Merger, EVI shall select a bank or trust company to act as exchange
         agent (the "Exchange Agent") for the issue of shares of EVI Common
         Stock upon surrender of certificates representing Shares.

                 (b)      Payment of Merger Consideration.  EVI shall take all
         steps necessary to enable and cause there to be provided to the
         Exchange Agent on a timely basis, as and when needed after the
         Effective Time of the Merger, certificates for the shares of EVI
         Common Stock to be issued upon the conversion of the Shares pursuant
         to Section 1.7.  EVI or the Surviving Corporation shall timely make
         available to the Exchange Agent any cash necessary to make payments in
         lieu of fractional shares.

                 (c)      Exchange Procedure.  As soon as reasonably practical
         after the Effective Time of the Merger, the Exchange Agent shall mail
         to each holder of record of a certificate or certificates that
         immediately prior to the Effective Time of the Merger represented
         outstanding Shares (the "Certificates"), other than EVI, Sub and
         GulfMark and any directly or indirectly wholly-owned subsidiary of
         EVI, Sub or GulfMark, (i) a letter of transmittal (which shall specify
         that delivery shall be effected, and risk of loss and title to the
         Certificates shall pass, only upon delivery of the Certificates to the
         Exchange Agent and shall be in a form and have such other provisions
         as EVI and Sub may reasonably specify) and (ii) instructions for use
         in effecting the surrender of the Certificates in exchange for the
         certificates representing the shares of EVI Common Stock and any cash
         in lieu of a fractional share.  Upon surrender of a Certificate for
         cancellation to the Exchange Agent or to such other agent or agents as
         may be appointed





                                       4
<PAGE>   9
         by the Surviving Corporation, together with such letter of
         transmittal, duly executed, and such other documents as may reasonably
         be required by the Exchange Agent, the holder of such Certificate
         shall be entitled to receive in exchange therefor a certificate or
         certificates representing the number of whole shares of EVI Common
         Stock into which the Shares theretofore represented by such
         Certificate shall have been converted pursuant to Section 1.7 and any
         cash payable in lieu of a fractional Share, and the Certificate so
         surrendered shall forthwith be canceled.  If the shares of EVI Common
         Stock are to be issued to an individual, corporation, limited
         liability company, partnership, governmental authority or any other
         entity (a "Person"),  other than the person in whose name the
         Certificate so surrendered is registered, it shall be a condition of
         exchange that such Certificate shall be properly endorsed or otherwise
         in proper form for transfer and that the Person requesting such
         exchange shall pay any transfer or other taxes required by reason of
         the exchange to a Person other than the registered holder of such
         Certificate or establish to the satisfaction of the Surviving
         Corporation that such tax has been paid or is not applicable.  Until
         surrendered as contemplated by this Section 1.8, each Certificate
         shall be deemed at any time after the Effective Time of the Merger to
         represent only the right to receive upon such surrender the number of
         shares of EVI Common Stock and cash, if any, in lieu of fractional
         shares of EVI Common Stock into which the Shares theretofore
         represented by such Certificate shall have been converted pursuant to
         Section 1.7.  The Exchange Agent shall not be entitled to vote or
         exercise any rights of ownership with respect to the shares of EVI
         Common Stock held by it from time to time hereunder, except that it
         shall receive and hold all dividends or other distributions paid or
         distributed with respect thereto for the account of Persons entitled
         thereto.

                 (d)      Distributions with Respect to Unexchanged Shares.  No
         dividends or other distributions declared or made after the Effective
         Time of the Merger with respect to the shares of EVI Common Stock with
         a record date after the Effective Time of the Merger shall be paid to
         the holder of any unsurrendered Certificate with respect to the shares
         of EVI Common Stock represented thereby and no cash payment in lieu of
         fractional shares shall be paid to any such holder pursuant to Section
         1.7(d) until the holder of record of such Certificate shall surrender
         such Certificate.  Subject to the effect of applicable laws, following
         surrender of any such Certificate, there shall be paid to the record
         holder of the Certificates representing the shares of EVI Common Stock
         issued in exchange therefor, without interest, (i) at the time of such
         surrender, the amount of any cash payable in lieu of a fractional
         share of EVI Common Stock to which such holder is entitled pursuant to
         Section 1.7(d) and the amount of dividends or other distributions with
         a record date after the Effective Time of the Merger theretofore paid
         with respect to such whole shares of EVI Common Stock, as the case may
         be, and (ii) at the appropriate payment date, the amount of dividends
         or other distributions with a record date after the Effective Time of
         the Merger but prior to surrender and a payment date subsequent to
         surrender payable with respect to such whole shares of EVI Common
         Stock.

                 (e)      No Further Ownership Rights in Shares.  All shares of
         EVI Common Stock issued upon the surrender of Certificates in
         accordance with the terms of this Article I, together with any
         dividends payable thereon to the extent contemplated by this Section
         1.8, shall be deemed to have been exchanged and paid in full
         satisfaction of all





                                       5
<PAGE>   10
         rights pertaining to the Shares theretofore represented by such
         Certificates and there shall be no further registration of transfers
         on the stock transfer books of the Surviving Corporation of the Shares
         that were outstanding immediately prior to the Effective Time of the
         Merger.  If, after the Effective Time of the Merger, Certificates are
         presented to the Surviving Corporation for any reason, they shall be
         canceled and exchanged as provided in this Article I.

                 (f)      None of EVI, Sub, GulfMark, the Surviving Corporation
         or their transfer agents shall be liable to a holder of the Shares for
         any amount properly paid to a public official pursuant to applicable
         property, escheat or similar laws.

         1.9     TAKING OF NECESSARY ACTION; FURTHER ACTION.  The parties
hereto shall take all such reasonable and lawful action as may be necessary or
appropriate in order to effectuate the Merger and the Distribution as promptly
as possible.  If, at any time after the Effective Time, any such further action
is necessary or desirable to carry out the purposes of this Agreement or the
Distribution Agreement, and to vest the Surviving Corporation with full right,
title and possession to all assets, property, rights, privileges, powers and
franchises of GulfMark or Sub as of the Effective Time, such corporations shall
direct their respective officers and directors to take all such lawful and
necessary action.

                                   ARTICLE II

                         REPRESENTATIONS AND WARRANTIES

         2.1     REPRESENTATIONS AND WARRANTIES OF EVI AND SUB.  EVI and Sub
hereby jointly and severally represent and warrant to GulfMark that:

                 (a)      Organization and Compliance with Law.  Each of EVI
         and Sub is a corporation duly organized, validly existing and in good
         standing under the laws of the state of Delaware and has all requisite
         corporate power and corporate authority to own, lease and operate all
         of its properties and assets and to carry on its business as now being
         conducted, except where the failure to be so organized, existing or in
         good standing would not have a material adverse effect on the
         financial condition of EVI and its subsidiaries (the "EVI
         Subsidiaries"), taken as a whole (an "EVI MAE").  Each of EVI and Sub
         is duly qualified to do business, and is in good standing, in each
         jurisdiction in which the property owned, leased or operated by it or
         the nature of the business conducted by it makes such qualification
         necessary, except in such jurisdictions where the failure to be duly
         qualified would not have an EVI MAE.  Each of EVI and Sub is in
         compliance with all applicable laws, judgments, orders, rules and
         regulations, except where such failure would not have an EVI MAE.  EVI
         has heretofore delivered to GulfMark true and complete copies of EVI's
         Certificate of Incorporation (the "EVI Certificate") and Sub's
         Certificate of Incorporation and their respective bylaws as in
         existence on the date hereof.

                 (b)      Capitalization.

                          (i)     The authorized capital stock of EVI consists
                 of 40,000,000 shares of EVI Common Stock, par value $1.00 per
                 share, and 3,000,000 shares of preferred stock, par value
                 $1.00 per shares ("EVI Preferred Stock").  As of September 30,
                 1996, there were issued and outstanding 22,939,625 shares of
                 EVI Common Stock.  As of October 8, 1996, 1,550,268 shares of
                 EVI Common Stock were reserved for issuance pursuant to EVI's
                 1981 Employee Stock Option Plan, 1992 Employee Stock Option
                 Plan, Non- Employee Director Stock Option Plan and restricted
                 stock plan for foreign key employees, of which 834,268 shares
                 of EVI Common Stock were reserved for issuance upon exercise
                 of outstanding options.  At October 8, 1996, there were no
                 shares of EVI Preferred Stock issued or outstanding.  No
                 holder of EVI Common Stock is entitled to preemptive rights
                 under Delaware law or EVI's Certificate of Incorporation.


                          (ii)    As of the date hereof, the authorized capital
                 stock of Sub consists of 1,000 shares of common stock, par
                 value $1.00 per share, all of which are validly issued, fully
                 paid and nonassessable and are owned by EVI.

                          (iii)   Each share of EVI Common Stock to be issued
                 hereunder as a result of the Merger will be fully paid and
                 non-assessable upon issuance.

                 (c)      Authorization and Validity of Agreement.  The
         execution and delivery by EVI and Sub of this Agreement and the
         consummation by each of them of the transactions contemplated hereby
         have been duly authorized by all necessary corporate action (subject
         only, with respect to the Merger, to approval of this Agreement by
         each of their stockholders as provided for in Section 5.3).  On or
         prior to the date hereof, the Board of Directors of EVI or duly
         authorized committee thereof has determined to recommend approval of
         the Merger to the stockholders of EVI, and such determination is in
         effect on the date hereof.  This Agreement has been duly executed and
         delivered by EVI and Sub and is the valid and binding obligation of
         EVI and Sub, enforceable against EVI and Sub in accordance with its
         terms.

                 (d)      No Approvals or Notices Required; No Conflict .
         Neither the execution and delivery of this Agreement nor the
         performance by EVI or Sub of its obligations hereunder, nor the
         consummation of the transactions contemplated hereby by EVI and Sub,

         2.2     REPRESENTATIONS AND WARRANTIES OF GULFMARK AND SPINCO.  Each
of GulfMark and Spinco, jointly and severally hereby represents and warrants to
EVI that:

                 (a)      Organization.  Each of GulfMark and Spinco is a
         corporation duly organized, validly existing and in good standing
         under the laws of the state of Delaware and Ercon Development Company,
         a wholly owned subsidiary of GulfMark to be merged into GulfMark prior
         to the Effective Time ("Ercon") is a corporation duly organized,
         validly existing and in good standing under the laws of the State of
         Texas.  Each of GulfMark, Spinco and Ercon has all requisite corporate
         power and corporate authority and all necessary governmental
         authorizations to own, lease and operate all of its properties and
         assets and to carry on its business as now being conducted, except
         where the failure to be so organized, existing or in good standing or
         to have such governmental authority would not (i) have a material
         adverse effect on the financial condition of GulfMark or Ercon after
         giving effect to the Distribution or (ii) prevent or adversely affect
         the ability of GulfMark and Spinco to perform and comply with their
         respective obligations under this Agreement, the Distribution
         Agreement or any other agreement to be executed and delivered in
         connection with the transactions contemplated hereby or thereby (a
         "GulfMark MAE").  Except as set forth in Section 2.2(a) of the
         disclosure letter delivered by GulfMark to EVI on the date hereof (the
         "GulfMark Disclosure Letter"), each of GulfMark, Ercon and Spinco is
         duly qualified as a foreign corporation to do business, and is in good
         standing, in each jurisdiction in which the property owned, leased or
         operated by it or the nature of the business conducted by it makes
         such qualification necessary, except in such jurisdictions where the
         failure to be duly qualified does not and would not have a GulfMark
         MAE.  Each of GulfMark, Ercon and Spinco is in compliance with all
         applicable laws, judgments, orders, rules and regulations, domestic
         and foreign, except where failure to be in such compliance would not
         have a GulfMark MAE.  GulfMark has heretofore delivered to EVI true
         and complete copies of GulfMark's Certificate of Incorporation (the
         "GulfMark Certificate") and bylaws, Spinco's Certificate of
         Incorporation and bylaws and Ercon's Articles of Incorporation and
         bylaws as in existence on the date hereof.

                 (b)      Capitalization.

                          (i)     The authorized capital stock of GulfMark
                 consists of 10,000,000 shares of GulfMark Common Stock, par

                 Common Stock and no shares of GulfMark Common Stock were held
                 as treasury shares.  There are no outstanding shares of

                 GulfMark Common Stock have been reserved for issuance pursuant
                 to the stock option plans described in Section 2.2(b)(iii).

                 validly issued, fully paid and nonassessable and no holder
                 thereof is entitled to preemptive rights.  GulfMark is not a
                 party to, and is not aware of, any voting agreement, voting

                 thereof is entitled to preemptive rights.  Ercon is not a
                 party to, any voting agreement, voting trust or similar
                 agreement or arrangement relating to any class or series of
                 its capital stock, or any agreement or arrangement providing
                 for registration rights with respect to any capital stock or
                 other securities of Ercon.  GulfMark owns all of the issued
                 and outstanding Common Stock of Ercon.

                          (iii)   As of the date hereof, there are outstanding

                 Director Stock Option Plan (collectively the "GulfMark
                 Plans").  All GulfMark Options will be transferred to Spinco's
                 Adjustment Plans prior to the Effective Time.  As of the
                 Effective Time, there will be no options outstanding under the
                 GulfMark Plans.  There are not now (other than as set forth in
                 this Section 2.2(b)), and at the Effective Time there will not
                 be, any (A) shares of capital stock or other equity securities
                 of GulfMark outstanding other than GulfMark Common Stock
                 issued pursuant to the exercise of GulfMark Options or (B)
                 outstanding options, warrants, scrip, rights to subscribe for,
                 calls or commitments of any character whatsoever relating to,
                 or securities or rights convertible into or exchangeable for,
                 shares of any class of capital stock of GulfMark, or
                 contracts, understandings or arrangements to which GulfMark is
                 a party, or by which it is or may be bound, to issue
                 additional shares of its capital stock or options, warrants,
                 scrip or rights to subscribe for, or securities or rights
                 convertible into or exchangeable for, any additional shares of
                 its capital stock.

                          (iv)    GulfMark owns all of the issued and 
                 outstanding Common Stock of Spinco.

                          (v)     Section 2.2(b)(v) of the GulfMark Disclosure
                 Letter sets forth a list of all corporations, partnerships,

         Section 13(a) of the Exchange Act as may be required in connection
         with this Agreement and the transactions contemplated hereby, (iii)
         the filing of a Certificate of Merger with the Delaware Secretary of
         State and the Texas Secretary of State with respect to the merger of
         Ercon into GulfMark and the filing of appropriate document(s) with the
         relevant authority of other states in which each of Ercon and GulfMark
         is qualified to do business, (iv) the filing of the Certificate of
         Merger with the Delaware Secretary of State with respect to the Merger
         as provided in the DGCL and appropriate documents with the relevant
         authorities of other states in which each of GulfMark and Spinco is
         qualified to do business and (v) such other consents, approvals,
         orders, authorizations, registrations, declarations, filings and
         notices as are set forth in Section 2.2(d) of the GulfMark Disclosure
         Letter.

                 (e)      Commission Filings; Financial Statements.  GulfMark
         has filed all reports, registration statements and other filings,
         together with any amendments required to be made with respect thereto,
         that they have been required to file with the Commission.  All
         reports, registration statements and other filings (including all
         notes, exhibits and schedules thereto and documents incorporated by
         reference therein) filed by GulfMark with the Commission since
         December 31, 1993 through the date of this Agreement, together with
         any amendments thereto, are sometimes collectively referred to as the
         "GulfMark Commission Filings."  GulfMark has heretofore delivered to
         EVI copies of the GulfMark Commission Filings.  As of the respective
         dates of their filing with the Commission, the GulfMark Commission
         Filings complied in all material respects with the Securities Act, the
         Exchange Act and the rules and regulations of the Commission
         thereunder, and did not contain any untrue statement of a material
         fact or omit to state a material fact required to be stated therein or
         necessary to make the statements made therein, in light of the
         circumstances under which they were made, not misleading.  To the best
         knowledge of GulfMark, all material contracts of GulfMark and its
         subsidiaries have been included in the GulfMark's filings with the
         Commission since the initial registration of its stock under the
         Exchange Act, except for those contracts not required to be filed
         pursuant to the rules and regulations of the Commission.

                 Each of the consolidated financial statements (including any
         related notes or schedules) included in the GulfMark Commission
         Filings was prepared in accordance with generally accepted accounting
         principles applied on a consistent basis (except as may be noted
         therein or in the notes or schedules thereto) and complied with the
         rules and regulations of the Commission.  Such consolidated financial
         statements fairly present the consolidated financial position of
         GulfMark as of the dates thereof and the results of operations, cash
         flows and changes in stockholders' equity for the periods then ended
         (subject, in the case of the unaudited interim financial statements,
         to normal year-end audit adjustments on a basis comparable with past
         periods).  As of the date hereof, GulfMark has no liabilities,
         absolute or contingent, that may reasonably be expected to have a
         GulfMark MAE, that are not reflected in the GulfMark Commission
         Filings,

         disclosed in the GulfMark Commission Filings or set forth in Section
         2.2(f) of the GulfMark Disclosure Letter, GulfMark and its
         subsidiaries have conducted their respective businesses only in the
         ordinary and usual course in accordance with past practice, and there
         has not been: (i) a GulfMark MAE or any other material adverse change
         in the financial condition, results of operations, assets or business
         of GulfMark, taken as a whole, or (ii) to the knowledge of GulfMark,
         any other condition, event or development that reasonably may be
         expected to result in any such material adverse change or a GulfMark
         MAE; (iii) any change by GulfMark or Ercon in its accounting methods,
         principles or practices; (iv) any revaluation by GulfMark or Ercon of
         any of its assets, including, without limitation, writing down the
         value of inventory or writing off notes or accounts receivable other

         practice; (v) any entry by GulfMark or Ercon into any commitment or
         transaction that would be material to GulfMark or Ercon; (vi) any
         declaration, setting aside or payment of any dividends or
         distributions in respect of the GulfMark Common Stock or any
         redemption, purchase or other acquisition of any of its securities;
         (vii) any damage, destruction or loss (whether or not covered by
         insurance) adversely affecting the properties or business of GulfMark
         or Ercon; (viii) any increase in indebtedness of borrowed money other
         than borrowing under existing credit facilities as disclosed in
         Section 2.2(f) of the GulfMark Disclosure Letter; (ix) any granting of
         a security interest or Lien on any property or assets of GulfMark or
         Ercon, other than (A) Liens for taxes not due and payable and (B)
         inchoate mechanics', warehousemen's and other statutory Liens incurred
         in the ordinary course of business (collectively, "Permitted Liens");
         or (x) any increase in or establishment of any bonus, insurance,
         severance, deferred compensation, pension, retirement, profit sharing,
         stock option (including, without limitation, the granting of stock
         options, stock appreciation rights, performance awards or restricted
         stock awards), stock purchase or other employee benefit plan or any
         other increase in the compensation payable or to become payable to any
         directors, officers or key employees of GulfMark or Ercon or which
         GulfMark or Ercon would be responsible.

                 (g)      Litigation.  Except as disclosed in the GulfMark
         Commission Filings or as set forth in Section 2.2(g) of the GulfMark
         Disclosure Letter, there are no claims, actions, suits,
         investigations, inquiries or proceedings, ("Demands"), pending or, to
         the knowledge of GulfMark, threatened against or affecting (i)
         GulfMark or Ercon or any of their respective properties at law or in
         equity, or any of their employee benefit plans or fiduciaries of such
         plans, or (ii) Spinco or any GulfMark or Spinco subsidiaries or any of
         their respective properties at law or in equity, or any of their
         respective employee benefit plans or fiduciaries of such plans, before
         or by any federal, state, municipal or other governmental agency or
         authority, or before any arbitration board or panel (each a
         "Governmental Entity"), wherever located (i) that exist today or (ii)
         that would otherwise, if adversely determined, have a GulfMark MAE.
         None of GulfMark, Ercon

                 (h)      Employee Benefit Plans.

                          (i)     Section 2.2(h) of the GulfMark Disclosure
                 Letter provides a description of each of the following which
                 is sponsored, maintained or contributed to by GulfMark or any
                 corporation, trade, business or entity under common control
                 with GulfMark within the meaning of Section 414(b), (c), (m)
                 or (o) of the Code or Section 4001 of ERISA (a "GulfMark ERISA

                          (ii)    Except as otherwise set forth in Section 
                 2.2(h) of the GulfMark Disclosure Letter,

                                  (C)      None of GulfMark or any GulfMark

<PAGE>   20
                                  (D)      Each Plan and each Benefit Program
                          or Agreement has been administered, maintained and
                          operated in all material respects in accordance with
                          the terms thereof and in compliance with its
                          governing documents and applicable law (including,
                          where applicable, ERISA and the Code and timely
                          filing of Form 5500's for each year);

                                  (E)      There is no matter pending with
                          respect to any of the Plans before any governmental
                          agency, and there are no actions, suits or claims
                          pending (other than routine claims for benefits) or,
                          to the knowledge of GulfMark or Spinco, threatened
                          against, or with respect to, any of the Plans or
                          Benefit Programs or Agreements or their assets;

                                  (F)      No act, omission or transaction has
                          occurred which would result in imposition on GulfMark
                          or any GulfMark ERISA Affiliate of breach of
                          fiduciary duty liability damages under Section 409 of
                          ERISA, a civil penalty assessed pursuant to

                          or a tax imposed pursuant to Chapter 43 of Subtitle D

                                  (G)      Except as provided in Section 5.7,
                          the execution and delivery of this Agreement and the
                          consummation of the transactions contemplated hereby
                          will not require GulfMark or any GulfMark ERISA
                          Affiliate to make a larger contribution to, or pay
                          greater benefits under, any Plan, Benefit Program or
                          Agreement than it otherwise would or create or give
                          rise to any additional vested rights or service
                          credits under any Plan or Benefit Program or
                          Agreement or cause the companies to make accelerated
                          payments.

                          (iii)   Except as set forth in Section 2.2(h) of the
                 GulfMark Disclosure Letter, termination of employment of any
                 employee of GulfMark or Ercon immediately after consummation
                 of the transactions contemplated by this Agreement would not
                 result in payments under the Plans, Benefit Programs or
                 Agreements which, in the aggregate, would result in imposition
                 of the sanctions imposed under Sections 280G and 4999 of the
                 Code.

                          (iv)    Each Plan may be unilaterally amended or
                 terminated in its entirety without liability except as to
                 benefits accrued thereunder prior to such amendment or
                 termination.

                          (v)     Except as set forth in Section 2.2(h) of the
                 GulfMark Disclosure Letter, none of the employees of GulfMark
                 or Ercon are subject to union or collective bargaining
                 agreements.

                          (vi)    None of GulfMark or any of the GulfMark ERISA
                 Affiliates has agreed or is obligated to provide retiree
                 medical coverage and each of such companies has fully complied
                 with all obligations under COBRA applicable to it.

                 (i)      Taxes.

                          (i)     Except as set forth in Section 2.2(i) of the
                 GulfMark Disclosure Letter, all Tax Returns of or relating to
                 any Tax that are required to be filed on or before the Closing
                 Date by or with respect to GulfMark or any GulfMark
                 Subsidiary, or any other corporation that is or was a member
                 of an affiliated group (within the meaning of Section 1504(a)
                 of the Code) of corporations of which GulfMark was a member
                 for any period ending on or prior to the Closing Date, have
                 been or will be duly and timely filed, and all Taxes,
                 including interest and penalties, due and payable pursuant to
                 such Tax Returns have been or will be duly and timely paid or
                 adequately provided for in reserves established by GulfMark or
                 any such GulfMark Subsidiary, except where the failure to
                 file, pay or provide for would not have a material adverse
                 effect on the financial condition, results of operations, or
                 business of GulfMark or otherwise result in a GulfMark MAE.
                 All income Tax returns of or with respect to GulfMark or any
                 GulfMark Subsidiary have been audited by the applicable
                 Governmental Authority, or the applicable statute of
                 limitations has expired, for all periods up to and including
                 the tax year ended December 31, 1991.  There is no material
                 claim against GulfMark or any GulfMark Subsidiary with respect
                 to any Taxes, and no material assessment, deficiency or
                 adjustment has been asserted or proposed with respect to any
                 Tax Return of or with respect to GulfMark or any GulfMark
                 Subsidiary that has not been adequately provided for in
                 reserves established by GulfMark or such GulfMark Subsidiary.
                 The total amounts set up as liabilities for current and
                 deferred Taxes in the consolidated financial statements
                 included in the GulfMark Commission Filings have been prepared
                 in accordance with generally accepted accounting principles
                 and are sufficient to cover the payment of all material Taxes,
                 including any penalties or interest thereon and whether or not
                 assessed or disputed, that are, or are hereafter found to be,
                 or to have been, due with respect to the operations of
                 GulfMark or any GulfMark Subsidiary through the periods
                 covered thereby.  GulfMark has (and as of the Closing Date
                 will have) made estimated tax payments for taxable years for
                 which the United States consolidated federal income Tax return
                 is not yet due required with respect to Taxes.  Except as set
                 forth in Section 2.2(i) of the GulfMark Disclosure Letter, no
                 waiver or extension of any statute of limitations as to any
                 federal, state, local or foreign Tax matter has been given by
                 or requested from GulfMark or any GulfMark Subsidiary.  Except
                 for statutory Liens for current Taxes not yet due, no Liens
                 for Taxes exist upon the assets of GulfMark.  Except as set
                 forth in paragraph 2.2(i) of the GulfMark Disclosure Letter,
                 none of GulfMark or any GulfMark Subsidiary has filed
                 consolidated income Tax Returns with any corporation, other
                 than consolidated federal, state or foreign income Tax returns
                 by GulfMark for any taxable period which is not now closed by
                 the applicable statute of limitations.  None of GulfMark or
                 any GulfMark Subsidiary has any deferred intercompany gain as
                 defined in Treasury Regulations Section 1.1502-13.

                          (ii)    As of the Closing Date, to GulfMark's
                 knowledge, there is no plan or intention by the stockholders
                 of GulfMark to sell, exchange or otherwise dispose of a number
                 of shares of EVI received in the Merger that would reduce





                                       17
<PAGE>   22
                 the GulfMark stockholders' ownership of EVI shares to a number
                 of shares having a value, as of the date of the Merger, of
                 less than 50% of the value of all of the formerly outstanding
                 Shares as of the same date.  For purposes of this
                 representation, Shares exchanged for cash or other property or
                 exchanged in lieu of fractional shares of EVI will be treated
                 as outstanding Shares on the date of the Merger.  Moreover,
                 the shares of EVI held by the GulfMark stockholders and
                 otherwise sold, redeemed or disposed of prior or subsequent to
                 the Merger will be considered in making this representation.

                          (iii)   GulfMark is not an investment company as
                 defined in Section 368(a)(2)(F)(iii) and (iv) of the Code.

                          (iv)    GulfMark is not under the jurisdiction of a
                 court in a Title 11 or similar case with the meaning of
                 Section 368(a)(3)(A) of the Code.

                          (v)     There is no intercorporate indebtedness
                 existing between GulfMark and EVI that was issued, acquired or
                 will be settled at a discount.

                 (j)      Environmental Matters.  Except as set forth in
         Section 2.2(j) of the GulfMark Disclosure Letter, (i) the properties,
         operations and activities of GulfMark and each of its subsidiaries
         complies in all material respects with all applicable Environmental
         Laws; (ii) none of GulfMark or any of its GulfMark Subsidiaries is
         subject to any existing, pending or, to the knowledge of GulfMark,
         threatened action, suit, investigation, inquiry or proceeding by or
         before any governmental authority under any Environmental Law; (iii)
         except where the failure would have a GulfMark MAE, all notices,
         permits, licenses, or similar authorizations, if any, required to be
         obtained or filed by GulfMark or Ercon under any Environmental Law in
         connection with any aspect of the business of GulfMark, Ercon or any
         GulfMark Subsidiary, including without limitation those relating to
         the treatment, storage, disposal or release of a hazardous substance
         or solid waste, have been duly obtained or filed and will remain valid
         and in effect after the Merger and the Distribution, and GulfMark and
         Ercon is in compliance with the terms and conditions of all such
         notices, permits, licenses and similar authorizations; (iv) GulfMark
         and each of its subsidiaries has satisfied and are currently in
         compliance with all financial responsibility requirements applicable
         to their operations and imposed by any governmental authority under
         any other Environmental Law, and none of such parties has received any
         notice of noncompliance with any such requirements; (v) to GulfMark's
         knowledge, there are no physical or environmental conditions existing
         on any property currently owned or previously owned by GulfMark or any
         entity in which it has or had ownership interest that could reasonably
         be expected to give rise to any on-site or off-site remedial
         obligations under any Environmental Laws; and (vi) to GulfMark's
         knowledge, since the effective date of the relevant requirements of
         applicable Environmental Laws, all hazardous substances or solid
         wastes generated by GulfMark or used in connection with their
         properties or operations have been transported only by carriers
         authorized under Environmental Laws to transport such substances and
         wastes, and disposed of only at treatment, storage, and disposal
         facilities authorized under environmental laws to treat, store or
         dispose of such substances and wastes, and, to the knowledge of
         GulfMark, such carriers and facilities have been and are operating





                                       18
<PAGE>   23
         in compliance with such authorizations and are not the subject of any
         existing, pending, or overtly threatened action, investigation, or
         inquiry by any governmental authority in connection with any
         Environmental Laws.

                 For purposes of this Agreement, the term "Environmental Laws"
         shall mean any and all laws, statutes, ordinances, rules, regulations,
         orders or determinations of any Governmental Authority pertaining to
         health or the environment currently in effect in any and all
         jurisdictions in which the party in question and its subsidiaries own
         property or conduct business, including without limitation, the Clean
         Air Act, as amended, the Comprehensive Environmental, Response,
         Compensation, and Liability Act of 1980 ("CERCLA"), as amended, the
         Federal Water Pollution Control Act, as amended, the Occupational
         Safety and Health Act of 1970, as amended, the Resource Conservation
         and Recovery Act of 1976 ("RCRA"), as amended, the Safe Drinking Water
         Act, as amended, the Toxic Substances Control Act, as amended, the
         Hazardous & Solid Waste Amendments Act of 1984, as amended, the
         Superfund Amendments and Reauthorization Act of 1986, as amended, the
         Hazardous Materials Transportation Act, as amended, the Oil Pollution
         Act of 1990 ("OPA"), any state laws pertaining to the handling of oil
         and gas exploration and production wastes or the use, maintenance, and
         closure of pits and impoundments, and all other environmental
         conservation or protection laws.  For purposes of this Agreement, the
         terms "hazardous substance" and "release" have the meanings specified
         in RCRA; provided, however, that to the extent the laws of the state
         in which the property is located establish a meaning for "hazardous
         substance," "release," "solid waste" or "disposal" that is broader
         than that specified in either CERCLA or RCRA, such broader meaning
         shall apply.  For purposes of this Agreement, the term "Governmental
         Authority" includes the United States, any foreign jurisdiction, the
         state, county, city, and political subdivisions in which the party in
         question owns property or conducts business, and any agency,
         department, commission, board, bureau or instrumentality of any of
         them.

                 (k)      Investment Company.  GulfMark is not an investment
         company as defined in the Investment Company Act of 1940 and the rules
         and regulations promulgated thereunder.

                 (l)      Severance Payments.  Except as set forth in Section
         2.2(l) of the GulfMark Disclosure Letter, GulfMark will not have any
         liability or obligation to pay a severance payment or similar
         obligation to any of their respective employees, officers, or
         directors as a result of the Merger or the transactions contemplated
         by this Agreement, nor will any of such Persons be entitled to an
         increase in severance payments or other benefits as a result of the
         Merger, the Contribution, the Distribution or the transactions
         contemplated by this Agreement or the Other Agreements in the event of
         the subsequent termination of their employment.

                 (m)      Voting Requirements.  The affirmative vote of the
         holders of a majority of the outstanding shares of GulfMark Common
         Stock is the only vote of the holders of any class or series of the
         capital stock of GulfMark necessary to approve this Agreement, the
         Merger, the Contribution, the Distribution and the transactions
         contemplated hereby





                                       19

         and by the Other Agreements in order to comply with the DGCL,

         regulations of The NASDAQ Stock Market.

                 (n)      Brokers.  Except for Jefferies & Company, Inc., whose
         fees shall be paid by GulfMark, no broker, investment banker, or other
         Person acting on behalf of GulfMark is or will be entitled to any
         broker's, finder's or other similar fee or commission in connection
         with the transactions contemplated by this Agreement.

                 (o)      Assets and Liabilities at Closing.  At the Effective
         Time:

                          (i)     the assets of GulfMark shall consist of (1)
                 2,235,572 shares of EVI Common Stock, which shall be held free
                 and clear of all Liens, (2) 200 shares of Common Stock of
                 AIOC, which represents all of the ownership interest of
                 GulfMark and the GulfMark Subsidiaries in AIOC, (3) all assets
                 used in connection with the business and operations previously
                 conducted by Ercon, (4) all tax, financial, accounting and
                 other general corporate records, including records relating to
                 all past operations and subsidiaries (including partnerships
                 and joint ventures) other than those constituting a part of
                 the  Assets, (5) GulfMark's accounts receivable (billed and
                 unbilled) relating to the business conducted by Ercon, (6)
                 cash in the amount of $300,000 and (7) cash in the amount of
                 the transactional expenses of GulfMark to be paid by GulfMark
                 relating to the Contribution, the Distribution and the Merger;

                          (ii)    the liabilities of GulfMark shall consist
                 only of certain expenses related to the Merger and the
                 Distribution which shall have been fully reserved for in the
                 Net Working Capital, and GulfMark's accounts payable relating
                 to the business conducted by Ercon, which shall have been
                 fully reserved for in the Net Working Capital;

                          (iii)   all obligations and liabilities (fixed or
                 contingent, known or unknown) of GulfMark shall have been
                 assumed by Spinco other than liabilities described in clause
                 (ii) and the obligation to perform in the future under
                 contracts relating to Ercon that will be identified on
                 schedules to the Distribution Agreement; and

                          (iv)    the Net Working Capital of GulfMark shall
                 equal $300,000.  "Net Working Capital" shall mean the current
                 assets of GulfMark excluding inventory, less the liabilities
                 of GulfMark as reflected on the balance sheet of GulfMark as
                 of the Effective Time on an unconsolidated basis.  Current
                 assets and liabilities shall have the meaning attributable to
                 them by generally accepted account principles as applied
                 historically by GulfMark, provided, however, for purposes of
                 the definition of Net Working Capital, (i) accounts receivable
                 shall be net of reserves for bad debt and doubtful accounts,
                 (ii) the stock of AIOC shall not be considered a current asset
                 and (iii) liabilities shall mean the full undiscounted amount
                 of any liabilities of GulfMark and Ercon, including any
                 liabilities that will accrue as a result of the Merger, the
                 Contribution or the Distribution, whether or





                                       20
<PAGE>   25
                 not such liabilities would be required to be reflected as a
                 liability by generally accepted accounting principles.

                 (p)      Compliance with Laws.  GulfMark, Spinco, Ercon  and
         each of their respective subsidiaries hold all required, necessary or
         applicable permits, licenses, variances, exemptions, orders,
         franchises and approvals of all Governmental Entities, except where
         the failure to so hold could not reasonably be expected to have a
         GulfMark MAE (the "GulfMark Permits").  All applications with respect
         to such permits, licenses, variances, exemptions, orders, franchises
         and approvals were complete and correct in all material respects when
         made and neither GulfMark nor Spinco know of any reason why any of
         such permits, licenses, variances, exemptions, orders, franchises and
         approvals would be subject to cancellation.  GulfMark, Spinco, Ercon,
         and each of their respective subsidiaries are in compliance with the
         terms of the GulfMark Permits except where the failure to so comply
         could not reasonably be expected to have a GulfMark MAE.  None of
         GulfMark, Spinco, Ercon, nor any of their respective subsidiaries has
         violated or failed to comply with any statute, law, ordinance,
         regulation, rule, permit or order of any Federal, state or local
         government, domestic or foreign, or any Governmental Entity, any
         arbitration award or any judgment, decree or order of any court or
         other Governmental Entity, applicable to GulfMark, Spinco, Ercon  or
         any of their respective subsidiaries or their respective business,
         assets or operations, except for violations and failures to comply
         that would not have a GulfMark MAE.

                 (q)      Contracts.

                          (i)     Section 2.2(q) to the GulfMark Disclosure

                 contracts and other agreements with respect to any property,

                 Ercon is contractually obligated; (iii) contracts or
                 commitments for capital expenditures or acquisitions in excess
                 of $30,000 to which GulfMark or Ercon is obligated; (iv)
                 agreements, contracts, indentures or other instruments
                 relating to the borrowing of money, or the guarantee of any

                 Ercon, Spinco or any of their subsidiaries is a party or any
                 of their respective properties is bound; (v) contracts or
                 agreements or amendments thereto that would be required to be
                 filed as an exhibit to an Annual Report on Form 10-K filed by
                 GulfMark as of the date hereof that has not been filed as an
                 exhibit to the GulfMark's Annual Report on Form 10-K for the
                 year ended December 31, 1995, filed by it with the Commission
                 or any report filed with the Commission under the Exchange Act

                 aware after reasonable investigation, (viii) all material
                 indemnification and guaranty or other similar obligations to
                 which GulfMark or Ercon is bound and which the officers of
                 GulfMark or Ercon, after reasonable investigation, are aware,
                 (ix) any





                                       21
<PAGE>   26
                 outstanding bonds, letters of credit posted or guaranteed by
                 GulfMark or Ercon with respect to any Person, (x) any
                 covenants not to compete or other obligations affecting
                 GulfMark or Ercon that would restrict the Surviving
                 Corporation or EVI and its affiliates from engaging in any
                 business or activity which the officers of GulfMark or Ercon
                 are aware, after reasonable investigation and (xi) contracts,
                 agreements, arrangements or commitments, other than the
                 foregoing that could reasonably be considered to be material
                 to GulfMark or Ercon.

                          (ii)    True and correct copies of all the
                 instruments described in Section 2.2(q) of the GulfMark
                 Disclosure Letter have been furnished or made a available to
                 EVI.  Except as noted in the GulfMark Disclosure Letter, all
                 such agreements, arrangements or commitments are valid and
                 subsisting and each of GulfMark, Ercon, Spinco and their
                 respective subsidiaries to the extent each is a party, has
                 duly performed its obligations thereunder in all material
                 respects to the extent such obligations have accrued, and no
                 breach or default thereunder by GulfMark,  Ercon, Spinco or
                 their respective subsidiaries or, to the knowledge of
                 GulfMark, any other party thereto has occurred that could
                 impair the ability of each of GulfMark, Ercon, Spinco or their
                 respective subsidiaries to enforce any material rights
                 thereunder.  There are no material liabilities of any of the
                 parties to any of the contracts between GulfMark, Ercon,
                 Spinco or any of their subsidiaries and third parties arising
                 from any breach of or default in any provision thereof or
                 which would permit the acceleration of any obligation of any
                 party thereto or the creation of a Lien upon any asset of
                 GulfMark, Ercon, Spinco or any of their subsidiaries.  Neither
                 GulfMark nor Ercon has any information that might reasonably
                 indicate that any of the material customers or suppliers to
                 Ercon  intend to cease purchasing from, selling to or dealing
                 with it, nor has any information been brought to the attention
                 of GulfMark or Ercon that might reasonably lead either to
                 believe any such customer or supplier intends to alter in any
                 material respect the amount of such purchases, sales or the
                 extent of dealings with GulfMark or Ercon or would alter in
                 any significant respect such purchases, sales or dealings in
                 the event of the consummation of the transactions contemplated
                 hereby.

                 (r)      Title to Property.

                          (i)     At the Effective Time, GulfMark will have
                 good and marketable title to, or valid leasehold interests in,
                 all its properties and assets.  GulfMark has good and valid
                 title to 2,235,572 shares of EVI Common Stock, free and clear
                 of all Liens.  GulfMark has good and valid title to 200 shares
                 of AIOC Common Stock, free and clear of all Liens.

                          (ii)    Each of GulfMark and Ercon has complied in
                 all material respects with the terms of all leases to which it
                 is a party and under which it is in occupancy, and all such
                 leases are in full force and effect.  Each of GulfMark and
                 Ercon enjoys peaceful and undisturbed possession under all
                 such leases.

                 (s)      Insurance Policies.  Section 2.2(s) of the GulfMark
         Disclosure Letter contains a correct and complete description of all
         insurance policies of GulfMark covering GulfMark, Ercon and their
         subsidiaries, any employees or other agents of GulfMark and its
         subsidiaries or any assets of GulfMark, Ercon and their subsidiaries.
         Each such policy is in full force and effect, is with responsible
         insurance carriers and is substantially equivalent in coverage and
         amount to policies covering companies of the size of GulfMark and in
         the business in which GulfMark and its subsidiaries is engaged, in
         light of the risk to which such companies and their employees,
         businesses, properties and other assets may be exposed.  All
         retroactive premium adjustments under any worker's compensation policy
         of GulfMark or any of its subsidiaries have been recorded in
         GulfMark's financial statements in accordance with generally accepted
         accounting principles and are reflected in the financial statements
         contained in the Commission Filings.

                 (t)      Loans.  Section 2.2(t) of the GulfMark Disclosure
         Letter sets forth all existing loans, advances or other extensions of
         credit (excluding accounts receivable arising in the ordinary course
         of business) by GulfMark or Ercon subsidiaries to any party other than
         intercompany loans, advances, guaranties or extensions of credit.  All
         items listed in Section 2.2(t) of the GulfMark Disclosure Letter will
         be repaid in full, or assumed by Spinco, prior to the Effective Time
         of the Merger.  All intercompany obligations and loans between
         GulfMark and its subsidiaries, including Spinco, will be extinguished
         prior to the Distribution without any ongoing liability to GulfMark or
         Spinco with respect thereto, except as set forth herein or in the
         Distribution Agreement.

                 (u)      No Fraudulent Transfer.  GulfMark has not within the
         last twelve months made any transfer or incurred any obligation with
         actual intent to hinder, delay or defraud any entity to which it was
         or may become indebted and it has not transferred any material
         property without receiving reasonably equivalent value for any such
         transfer obligation.  Both immediately prior to and immediately after
         the Distribution and the Merger, (i) the fair value of GulfMark's
         assets and Spinco's assets after the Distribution at a fair valuation
         exceeds its debts and liabilities, subordinated, contingent or
         otherwise, (ii) the present fair saleable value of GulfMark's and
         Spinco's property is greater than the amount that will be required to
         pay its probable liability on its debts and other liabilities,
         subordinated, contingent or otherwise, as such debts and liabilities
         become absolute and mature, (iii) GulfMark prior to the Distribution
         and Spinco after the Distribution each reasonably expect to be able to
         pay its debts and liabilities, subordinated, contingent or otherwise,
         as such debts and liabilities become absolute and matured, and (iv)
         GulfMark before the Distribution and Spinco after the Distribution
         will not have unreasonably small capital with which to conduct the
         business in which it is engaged as such business is now conducted and
         is proposed to be conducted.  For all purposes of clauses of (i)
         through (iv), the amount of contingent liabilities at any time shall
         be computed as the amount that, in light of all the facts and
         circumstances existing at such time, represents the amount that can
         reasonably be expected to become an actual or matured liability.

                 (v)      Information Supplied.  None of the information
         supplied or to be supplied by GulfMark for inclusion or incorporation
         by reference in (i) the Registration Statement





                                       23

         (as defined in Section 5.1) will, at the time the Registration
         Statement is filed with the Commission, and at any time it is amended
         or supplemented or at the time it becomes effective under the
         Securities Act, contain any untrue statement of a material fact or
         omit to state any material fact required to be stated therein or
         necessary to make the statements therein not misleading, and (ii) the
         Proxy Statement will, at the date the Proxy Statement is first mailed
         to GulfMark's stockholders and at the time of the GulfMark
         Stockholders Meeting, contain any untrue statement of a material fact
         or omit to state any material fact required to be stated therein or
         necessary in order to make the statements therein, in light of the
         circumstances under which they are made, not misleading.  The Proxy
         Statement will comply as to form in all material respects with the
         requirements of the Exchange Act and the rules and regulations
         thereunder.  For purposes of this Agreement, the parties agree that
         the statements made and information in the Registration Statement and
         the Proxy Statement relating to the Federal income tax consequences of
         the transactions contemplated hereby shall be deemed to be supplied by
         GulfMark and Spinco and not by EVI or Sub.

         uncollected accounts receivable (including uncollected unbilled

         ("Uncollected Receivables"), Spinco shall purchase from GulfMark such
         Uncollected Receivables for the face amounts thereof and GulfMark
         shall assign such Uncollected Receivables to Spinco without recourse;

                 (b)      on the Adjustment Date after any purchase of
         Uncollected Receivables, if it is determined that as of the Effective
         Time Net Working Capital exceeded $300,000, GulfMark shall remit any
         amounts in excess of $300,000 to Spinco in cash;

                 (c)      on the Adjustment Date, after any purchase of

         consideration of purchases of Uncollected Receivables);

                 (d)      the provisions of this Section 3.2 shall not affect
         Spinco's obligations under the Distribution Agreement to assume and
         indemnify EVI as set forth therein.

         3.3     AFFILIATES' AGREEMENTS.  Prior to the Closing Date, GulfMark

"affiliates" of GulfMark for purposes of Rule 145 under the Securities Act.

to EVI on or prior to the Closing Date a written agreement confirming such
Person's obligations under Rule 145.

securities and blue sky laws, (iii) the listing of the EVI Common Stock on the
NYSE, (iv) the HSR filing fee and (v) the printing and mailing of the
Registration Statement and the Proxy Statement shall be paid equally by EVI and
GulfMark; provided, however, that if this Agreement shall have been terminated
pursuant to Section 7.1 as a result of the willful breach by a party of any of
its representations, warranties, covenants, or agreements set forth in this
Agreement, such breaching party shall pay the direct out-of-pocket costs and
expenses of the other parties in connection with the transactions contemplated
by this Agreement.

         5.7     GULFMARK'S EMPLOYEE BENEFITS.

                 (a)      GulfMark shall take action prior to the Merger and
         the Distribution to transfer the GulfMark Options to the Spinco
         adjustment plans and then terminate the GulfMark Plans such that all
         obligations with respect thereto shall be that of Spinco.

                 (b)      Subject to the receipt of a favorable Internal
         Revenue Service determination letter under Section 401(a) and 501(a)
         of the Code with respect to GulfMark 401(k) Plan and resolution of any
         outstanding issues regarding the GulfMark 401(k) Plan in a manner
         satisfactory to EVI's counsel, EVI will cause the GulfMark 401(k) Plan
         to be merged into an EVI plan qualified under Section 401(a) and
         501(a) of the Code ("EVI Plan").  Spinco shall be responsible for and
         perform any and all obligations relating to the (i) filing of the
         GulfMark 401(k) Plan for a determination letter under Section 401(a)
         and 501(a) of the Code and (ii) resolution of any issues regarding the
         GulfMark 401(k) Plan, both to the satisfaction of EVI's counsel, so
         that EVI will cause the GulfMark 401(k) Plan to be merged into the EVI
         Plan. GulfMark and EVI, upon being satisfied with the filings and
         documentation prepared by Spinco in satisfaction of obligations (i)
         and (ii) above, shall execute and deliver such filings and documents
         as required to effect the merger of the GulfMark 401(k) Plan and the
         EVI Plan.  All reasonable costs, including attorneys fees, filing
         fees, transfer fees, settlement payments and other expenses, not
         otherwise satisfied by Spinco as stated herein, relating to the
         continuation, qualification and merger of the GulfMark 401(k) Plan
         shall be paid by Spinco.  Once the GulfMark 401(k) Plan is merged into
         an EVI Plan, Spinco shall not be responsible for liabilities relating
         to the GulfMark 401(k) Plan occurring after the merging of such plans.

                 (c)      GulfMark shall transfer to Spinco all employees of
         GulfMark who are not directly associated with the business conducted
         by Ercon without any liability to the Surviving Corporation.  Spinco
         shall be responsible for all severance and other obligations with
         respect to such terminated employees, if any.

                 (d)      Prior to the Effective Time, Spinco shall file a
         registration statement on Form S-8 (or other appropriate form) with
         respect to the shares of Spinco Common Stock subject to the adjusted
         GulfMark options, and shall use its best efforts to maintain the
         effectiveness of such registration statement (and maintain the current
         status of any prospectus contained therein) for so long as any of the
         adjusted GulfMark options remain outstanding.

         and adopted by the requisite vote of the stockholders of GulfMark and
         EVI, as may be required by law, by the rules of The Nasdaq Stock

         provisions of their respective charters or bylaws;

                 (c)      The waiting period (and any extension thereof)

         the Merger and the transactions contemplated thereby will be in
         compliance with applicable laws, the failure to comply with which

         granting of which is necessary for the consummation of the Merger, the
         Distribution or the transactions contemplated in connection therewith
         and (ii) the non-receipt of which would have a GulfMark MAE or an EVI
         MAE.

         the Merger in a manner adverse to GulfMark or shall have resolved to
         do any of the foregoing.

         EVI of such breach and is existing at the time of termination of this
         Agreement; (ii) any representation or warranty of GulfMark contained

         to the extent it relates to a particular date), except for such
         failures to be so true and correct which would not individually or in
         the aggregate, reasonably be expected to have a GulfMark MAE assuming
         the effectiveness of the Merger or (iii) the Board of Directors of
         GulfMark withdraws, modifies or changes its recommendation of this
         Agreement or the Merger in a manner adverse to EVI or shall have
         resolved to do any of the foregoing.

         7.2     EFFECT OF TERMINATION.  In the event of termination of this
Agreement by either EVI or GulfMark as provided in Section 7.1, this Agreement
shall forthwith become void and there shall be no liability or obligation on
the part of EVI, Sub or GulfMark, except (i) with respect to this Section 7.2,
Section 5.7 and Section 7.13, and (ii) such termination shall not relieve any
party hereto for any intentional breach prior to such termination by a party
hereto of any of its representations or warranties or of any of its covenants
or agreements set forth in this Agreement.

waived at any time by the party that is, or whose stockholders are, entitled to
the benefits thereof.  This Agreement may not be amended or supplemented at any
time, except by an instrument in writing signed on behalf of each party hereto,
provided that after this Agreement has been approved and adopted by the
stockholders of EVI and GulfMark, this Agreement may be amended only as may be
permitted by applicable provisions of the DGCL.  The waiver by any party hereto
of any condition or of a breach of another provision of this Agreement shall
not operate or be construed as a waiver of any other condition or subsequent
breach.  The waiver by any party hereto of any of the conditions precedent to
its obligations under this Agreement shall not preclude it from seeking redress
for breach of this Agreement other than with respect to the condition so
waived.

         7.4     NONSURVIVAL OF REPRESENTATIONS AND WARRANTIES.  Except for the
representations and warranties of Spinco contained herein, which shall survive

         7.8     GOVERNING LAW.  All questions arising out of this Agreement
and the rights and obligations created herein, or its validity, existence,
interpretation, performance or breach shall be governed by the laws of the
State of Delaware, without regard to conflict of laws principles.

         7.9     ARBITRATION.   Any disputes, claims or controversies connected
with, arising out of, or related to, this Agreement and the rights and
obligations created herein, or the breach, validity, existence or termination
hereof, shall be settled by Arbitration to be conducted in accordance with the
Commercial Rules of Arbitration of the American Arbitration Association, except
as such Commercial Rules may be changed by this Section 7.9.  The disputes,
claims or controversies shall be decided by three independent arbitrators (that
is, arbitrators having no substantial economic or other material relationship
with the parties), one  to be appointed by Spinco and one to be appointed by
EVI within fourteen days following the submission of the claim to the parties
hereto and the third to be appointed by the two so appointed within five days.
Should either party refuse or neglect to join in the timely appointment of the
arbitrators, the other party shall be entitled to select both arbitrators.
Should the two arbitrators fail  timely to appoint a third arbitrator, either
party may apply to the Chief Judge of the United States District Court for the
Southern District of Texas to make such appointment.  The arbitrators shall
have ninety days after the selection of the third arbitrator within which to
allow discovery, hear evidence and issue their decision or award and shall in
good faith attempt to comply with such time limits; provided, however, if two
of the three  arbitrators believe additional time is necessary to reach a
decision, they may notify the parties and extend the time to reach a decision
in thirty day increments, but in no event to exceed an additional ninety days.
Discovery of evidence shall be conducted expeditiously by the Parties, bearing
in mind the Parties desire to limit discovery and to expedite the decision or
award of the arbitrators at the most reasonable cost and expense of the
parties.  Judgment upon an award rendered pursuant to such Arbitration may be
entered in any court having jurisdiction, or application may be made to such
court for a judicial acceptance of the award, and an order of enforcement, as
the case may be. The place of Arbitration shall be Houston, Texas.  The
decision of the arbitrators, or a majority thereof, made in writing, shall be
final and binding upon the parties hereto as to the questions submitted, and
each party shall abide by such decision.  Notwithstanding the provisions of
this Section 7.9, neither party shall be prohibited from seeking injunctive
relief pending the completion of any arbitration.  The costs and expenses of
the arbitration proceeding, including the fees of the arbitrators and all costs
and expenses, including legal fees and witness fees, incurred by the prevailing
party, shall be borne by the losing party.

         Solely for purposes of injunctive relief, orders in aid of arbitration
and entry of the arbitrators' award:

                 (a)      each of the parties hereto irrevocably consents to
         the non-exclusive jurisdiction of, and venue in, any state court
         located in Harris County, Texas or any federal court sitting in the
         Southern District of Texas in any suit, action or proceeding seeking
         injunctive relief, orders in aid of arbitration, or entry of an
         arbitral award arising out of or relating to this Agreement or any of
         the other agreements contemplated hereby and any other court in which
         a matter that may result in a claim for indemnification hereunder by
         an EVI Indemnified Party may be brought with respect to any claim for
         indemnification by an EVI Indemnified Party;

<PAGE>   42
                 (b)      each of the parties hereto waives, to the fullest
         extent permitted by law, any objection that it may now or hereafter
         have to the laying of venue of any suit, action or proceeding seeking
         injunctive relief, orders in aid of arbitration or entry of an
         arbitral award arising out of or relating to this Agreement or any of
         the other agreements contemplated hereby brought in any state court
         located in Harris County, Texas or any federal court sitting in the
         Southern District of Texas or any other court in which a matter that
         may result in a claim for indemnification hereunder by an EVI
         Indemnified Party may be brought with respect to any claim for
         indemnification by an EVI Indemnified Party, and further irrevocably
         waive any claim that any such suit, action or proceeding brought in
         any such court has been brought in an inconvenient forum;

                 (c)      each of the parties hereto irrevocably designates,
         appoints and empowers CT Corporation System, Inc. and any successor
         thereto as its designee, appointee and agent to receive, accept and
         acknowledge for and on its behalf, and in respect of its property,
         service of any and all legal process, summons, notices and documents
         which may be served in any suit, action or proceeding arising out of
         or relating to this Agreement or any of the other agreements
         contemplated hereby for the purposes of injunctive relief, orders in
         aid of arbitration and entry of an arbitral award..

         7.10    SEVERABILITY.  If any term, provision, covenant or restriction
of this Agreement is held by a court of competent jurisdiction to be invalid,
void or unenforceable, the remainder of the terms, provision, covenants and
restrictions of this Agreement shall continue in full force and effect and
shall in no way be affected, impaired or invalidated.

         7.11    COUNTERPARTS.  This Agreement may be executed in counterparts,
each of which shall be an original, but all of which together shall constitute
one and the same agreement.

         7.12    HEADINGS.  The Section headings herein are for convenience
only and shall not affect the construction hereof.

         7.13    CONFIDENTIALITY AGREEMENT.  The Confidentiality Agreement
entered into between EVI and GulfMark on October 21, 1996 (the "Confidentiality
Agreement") is hereby incorporated by reference herein and made a part hereof.

         7.14    ENTIRE AGREEMENT: THIRD PARTY BENEFICIARIES.  This Agreement,
the Other Agreements and the Confidentiality Agreements constitute the entire
agreement and supersede all other prior agreements and understandings, both
oral and written, among the parties or any of them, with respect to the subject
matter hereof and neither this nor any document delivered in connection with
this Agreement confers upon any Person not a party hereto any rights or
remedies hereunder except as provided in Sections 5.6 and 5.7.

         3.1     Spinco Capitalization.  The current equity capitalization of
Spinco consists of one issued and outstanding share of Spinco Common Stock (the
"Existing Spinco Common Stock"), all of which is outstanding and owned
beneficially and of record by the Company.





                                     - 11 -

         3.2     Recapitalization of Spinco.  Immediately prior to the
Distribution Date, the GulfMark shall cause Spinco to exchange the Existing
Spinco Common Stock owned by GulfMark for the Additional Shares.

         3.3     Mechanics of Distribution.  The Distribution shall be effected
by the distribution to each holder of record of GulfMark Common Stock, as of
the record date designated for the Distribution by or pursuant to the
authorization of the Board of Directors of GulfMark (the "Record Date"), of
certificates representing two shares of Spinco Common Stock for each share of
GulfMark Common Stock held by such holder.

         3.4     Timing of Distribution.  The Board of Directors of the
GulfMark shall formally declare the Distribution and shall authorize GulfMark
to pay it immediately prior to the Effective Date, subject to the satisfaction
or waiver of the conditions set forth in Article VIII, by delivery of
certificates for Spinco Common Stock to the Transfer Agent for delivery to the
holders entitled thereto.  The Distribution shall be deemed to be effective
upon notification by GulfMark to the Transfer Agent that the Distribution has
been declared and that the Transfer Agent is authorized to proceed with the
distribution of Spinco Common Stock.

                                   ARTICLE IV

                             EMPLOYEE BENEFIT PLANS

         4.1     Employee Benefits Generally.  All obligations of the Spinco
under this Article IV with respect to employee benefit plans, arrangements or
policies for the benefit of employees and former employees (and their
beneficiaries) of GulfMark and the GulfMark Companies in place immediately
prior to the Contribution Date shall be treated as Assumed Liabilities and not
as Retained Liabilities under this Agreement.

         4.2     As soon as administratively possible after the Distribution
Date, Spinco shall  establish a defined contribution plan (the "Spinco 401(k)
Plan") which shall be qualified under Section 401(a) of the Internal Revenue
Code of 1986, as amended, and effective as of the Distribution Date.  As soon
as administratively feasible following the Distribution Date, and in accordance
with the terms of the GulfMark 401(k) Plan, GulfMark shall cause the account
balance attributable to each individual who will cease to be an employee of
GulfMark following the Distribution Date to be distributed directly to such
individual, or upon the request of any such individual, transferred to another
qualified rollover investment (including the Spinco 401(k) Plan if such
individual is eligible to participate therein) specified in such request to the
extent that such transfer or distribution is permitted by law.  Each individual
who becomes an employee of Spinco on the Distribution Date shall, for
eligibility and vesting purposes under the Spinco 401(k) Plan, be credited with
the same service with which he or she is credited for such purposes under the
GulfMark 401(k) Plan immediately prior to the Distribution Date.

         4.3     Employee Health, Life and Disability Insurance Plans.
Effective as of the Distribution Date, Spinco shall establish such employee
health, life and disability insurance plans and other employee welfare or
fringe benefit arrangements (collectively the "Spinco Employee





                                     - 12 -
<PAGE>   14
Benefit Plans") which are comparable in the aggregate to the health, life and
disability insurance plans and other employee welfare or fringe benefit
arrangements which had been maintained by GulfMark for its employees and the
employees of its Subsidiaries prior to the Distribution Date (collectively the
"GulfMark Employee Benefit Plans").  Service by any employee with GulfMark or
its Subsidiaries prior to the Distribution Date shall be counted for purposes
of determining any period of eligibility to participate in, or to vest in
benefits (including vacation rights) provided under, the Spinco Employee
Benefit Plans, and any amounts previously expended by any such employees of
GulfMark or its Subsidiaries prior to the Distribution Date for purposes of
satisfying such plan year's deductible, co-payment limitations maximum
out-of-pocket provisions and applicable annual and/or life-time maximum benefit
limitations shall be credited for purposes of satisfying such plan year's
deductible, co-payment limitations under the Spinco Employee Benefit Plans and
any coverage waiting period for pre-existing conditions for such employees
shall be waived under the Spinco Employee Benefit Plans.

                                   ARTICLE V

                          GULFMARK STOCK OPTION PLANS

         5.1     As of the Distribution Date, Spinco shall assume the GulfMark
Stock Option Plans, and pursuant to the equitable adjustment provisions of the
applicable Stock Option Plan, each outstanding stock option previously granted
pursuant to any of GulfMark's Stock Option Plans to an employee, officer or
director of GulfMark who will, following the Distribution, become an employee,
officer or director of Spinco, will be converted into and represent an option
to acquire shares of Spinco Common Stock.

         5.2     The number of shares of Spinco Common Stock subject to, and
the exercise price of, each such Spinco option will be adjusted in accordance
with the requirements of Section 424 of the Internal Revenue Code of 1986, as
amended, and the regulations promulgated thereunder, to reflect the
Distribution as set forth in Section 5.3 so that (i) the aggregate intrinsic
value (difference between market value per share and exercise price) of each
option immediately after the Distribution is not greater than the aggregate
intrinsic value of such option immediately before the Distribution, and (ii)
the ratio of the exercise price per option to the market value per share is not
reduced.  The vesting provisions and option period of the new Spinco options
will remain unchanged from the GulfMark options so replaced.

         5.3     As of the Distribution Date, to effect the adjustment
described in Section 5.2, (i) the number of shares of Spinco Common Stock
covered by each new Spinco option shall be the number of shares covered by the
GulfMark option being replaced thereby, multiplied by a fraction equal to the
ratio of the pre-Distribution market price per share of GulfMark Common Stock
to the post-Distribution market price per share of Spinco Common Stock, and
(ii) the exercise price per share of each new Spinco option shall be the
exercise price per share of the GulfMark option being replaced thereby,
multiplied by a fraction equal to the ratio of the post-Distribution market
price per share of the Spinco Common Stock to the pre-Distribution market price
per share of GulfMark Common Stock.





                                     - 13 -
<PAGE>   15
         5.4     For purposes of the foregoing adjustments, (i) the
pre-Distribution market price per Share of GulfMark Common Stock shall be
deemed to be the average of the arithmetic mean between the highest and lowest
sales prices per share of GulfMark Common Stock as reported by the NASDAQ Stock
Market on each of the ten trading days before the Distribution or such other
market price as the Board of Directors of Spinco deems equitable, and (ii) the
post- Distribution market price per share of Spinco Common Stock shall be
deemed to be the average of the arithmetic mean between the highest and lowest
sales prices per share of Spinco Common Stock as reported by the NASDAQ Stock
Market on each of the ten trading days beginning on the eleventh trading day
after the Distribution or such other market price as the Board of Directors of
Spinco deems equitable.

         5.5     GulfMark and Spinco will cooperate and take all action
necessary (including obtaining the consent of the holders of GulfMark options,
if required) to amend (if necessary) the GulfMark Stock Option Plans or
otherwise provide for adjustments of authorized shares and outstanding option
awards under the GulfMark Stock Option Plans, and to effect Spinco's assumption
of the GulfMark Stock Option Plans, in accordance with the provisions of this
Article V.

                 (b)      Absolute Indemnity.  NONE OF THE EVI INDEMNIFIED
        PARTIES WILL BE OBLIGATED TO INSTITUTE ANY LEGAL PROCEEDINGS IN
        CONNECTION WITH THE COLLECTION OR PURSUIT OF ANY INSURANCE IN ORDER TO
        EXERCISE AN INDEMNIFICATION REMEDY UNDER THIS ARTICLE VI.  UNLESS
        OTHERWISE SPECIFICALLY EXPRESSED, THIS INDEMNITY OBLIGATION SHALL APPLY
        WITHOUT REGARD TO WHETHER THE LIABILITY OR ENVIRONMENTAL LIABILITY WAS
        CAUSED BY THE ORDINARY OR GROSS NEGLIGENCE OF ANY OF THE EVI
        INDEMNIFIED PARTIES (WHETHER SUCH NEGLIGENCE BE SOLE, JOINT OR
        CONCURRENT OR ACTIVE OR PASSIVE), OR WHETHER THE LIABILITY OR
        ENVIRONMENTAL LIABILITY IS BASED ON STRICT LIABILITY, ABSOLUTE
        LIABILITY OR ARISES AS AN OBLIGATION OF CONTRIBUTION OR INDEMNITY.
        SPINCO ACKNOWLEDGES THAT IT IS AWARE OF VARIOUS THEORIES KNOWN AS THE
        "EXPRESS NEGLIGENCE" DOCTRINE AND OTHER SIMILAR DOCTRINES AND THEORIES
        THAT MAY LIMIT INDEMNIFICATION AND AGREES AND STIPULATES THAT THE
        PROVISIONS OF THIS AGREEMENT REFLECT THE EXPRESS INTENT OF THE PARTIES
        THAT THE INDEMNIFICATION TO BE PROVIDED BY SPINCO APPLY NOTWITHSTANDING
        THE FACT THAT THE LIABILITY OR ENVIRONMENTAL LIABILITY (I) MAY NOT
        CURRENTLY BE KNOWN BY IT OR MANIFEST ITSELF IN ANY REGARD, (II) MAY
        ARISE UNDER A STATUTE

        OR THEORY THAT MAY NOT CURRENTLY EXIST OR BE KNOWN TO SPINCO, (III) MAY
        ARISE AS A RESULT OF A NEGLIGENT ACT OR OMISSION BY ANY OF THE EVI
        INDEMNIFIED PARTIES (WHETHER SUCH CONDUCT BE SOLE, JOINT OR CONCURRENT
        OR ACTIVE OR PASSIVE) OR (IV) MAY CONSTITUTE A VIOLATION OF ANY
        APPLICABLE CIVIL OR CRIMINAL LAW OR REGULATION.

        6.2      Notice of Circumstance.  After receipt by EVI of notice, or
EVI's actual discovery, of any action, proceeding, claim, demand or potential
claim which could give rise to a right to indemnification pursuant to any
provision of this Agreement (any of which is individually referred to as a
"Circumstance"), EVI shall give Spinco written notice describing the
Circumstance in reasonable detail; provided, however, that no delay by EVI in
notifying Spinco shall relieve Spinco from any Liability or Environmental
Liability hereunder unless (and then solely to the extent) Spinco's position is
actually adversely prejudiced.  In the event Spinco notifies EVI within 15 days
after such notice that Spinco is assuming the defense thereof, (i) Spinco will
defend the EVI Indemnified Parties against the Circumstances with counsel of
its choice, provided such counsel is reasonably satisfactory to EVI, (ii) the
EVI Indemnified Parties may retain separate co-counsel at its or their sole
cost and expense (except that Spinco will be responsible for the fees and
expenses for the separate co-counsel to the extent EVI concludes reasonably
that the counsel Spinco has selected has a conflict of interest), (iii) the EVI
Indemnified Parties will not consent to the entry of any judgment or enter into
any settlement with respect to the Circumstances without the written consent of
Spinco and (iv) Spinco will not consent to the entry of any judgment with
respect to the Circumstances, or enter into any settlement which (x) requires
any payments by or continuing obligations of an EVI Indemnified Party, (y)
requires an EVI Indemnified Party to admit any facts or liability that could
reasonably be expected to adversely affect an EVI Indemnified Party in any
other matter or (z) does not include a provision whereby the plaintiff or
claimant in the matter releases the EVI Indemnified Parties from all Liability
with respect thereto, without the written consent of EVI.  In the event Spinco
does not notify EVI within 15 days after EVI has given notice of the
Circumstance that Spinco is assuming the defense thereof, the EVI Indemnified
Parties may defend against, or enter into any settlement with respect to, the
Circumstance in any manner the EVI Indemnified Parties reasonably may deem
appropriate, at Spinco's sole cost.  The foregoing provisions shall not apply
to the provisions of Section 5.7 of the Merger Agreement.

        6.3      Insurance.  Spinco shall not be obligated to indemnify the EVI
Indemnified Parties for amounts which shall have been covered and paid by
insurance of the EVI Indemnified Parties, provided, however, insurance shall
not include deductibles or self-insured retentions.

        6.4      Scope of Indemnification.  INDEMNIFICATION UNDER THIS ARTICLE
VI SHALL BE IN ADDITION TO ANY REMEDIES THE GULFMARK, EVI OR ANY EVI
INDEMNIFIED PARTY MAY HAVE AT LAW OR EQUITY.  THERE SHALL BE NO TIME LIMIT AS
TO SPINCO'S INDEMNIFICATION OBLIGATIONS  HEREUNDER.

        6.5      Indemnity for Certain Environmental Liabilities.  It is the
intention of the parties that the indemnity provided herein with respect to
Environmental Liabilities under CERCLA and





                                     - 17 -

corresponding provisions of state law is an agreement expressly not barred by
42 U.S.C. Section  9607(e)(i) and corresponding provisions of state law.

                                  ARTICLE VII

                         ADDITIONAL COVENANTS OF SPINCO

        7.1      Employment.  Spinco shall offer employment or continued
employment from the Contribution Date to all employees of GulfMark, except
those employed by Ercon, on terms that are substantially the same as the terms
on which they were employed by GulfMark immediately  prior to the Contribution
Date; provided, however, that nothing contained in this Section 7.1 is intended
to confer upon any employee who so continues to be employed or who accepts such
an offer of employment by Spinco ("Spinco Group Continuing Employees") any
right to continued employment after the Contribution Date.  GulfMark hereby
consents to Spinco making such offers.  Spinco shall recognize the service with
GulfMark through the Contribution Date of each Spinco Group Continuing Employee
and shall credit on the Contribution Date, such service with Spinco (i) for all
plan purposes under any employee benefit plan, arrangement or policy of the
Spinco Group in effect as of the Contribution Date in which they are then
participating and (ii) for eligibility and vesting purposes only under any
employee benefit plan, arrangement or policy for which they become eligible on
or following the Contribution Date.

        7.2      Spinco Covenants.  To assure the performance of the
obligations of Spinco under this Agreement, Spinco hereby covenants and agrees
that it will not, and will cause its Subsidiaries to not, merge, convert into
another entity, engage in a share exchange for a majority of its shares,
liquidate or transfer, assign or otherwise convey or allocate, directly or
indirectly, in one or more transactions, whether or not related, a majority of
Spinco's assets (determined in good faith by a board resolution prior to the
transaction on a fair value and consolidated basis) to any Person unless the
acquiring Person expressly assumes the obligations of Spinco hereunder, (ii)
executes and delivers to GulfMark and EVI an agreement agreeing to be bound by
each and every provision of this Agreement as if it were Spinco and (iii) has a
net worth on a pro forma basis after giving effect to the acquisition or
business combination equal to or greater than that of Spinco (on a consolidated
basis).

        7.3      Tax Allocation Agreement.  Prior to the Distribution,
GulfMark, Spinco and EVI shall enter into a Tax Allocation Agreement acceptable
in all respects to EVI and Spinco, which will set forth each party's rights and
obligations with respect to payments and refunds, if any, of Taxes for periods
before and after the Effective Date and related matters such as the filing of
tax returns and the conduct of audits and other tax proceedings.

                 (c)      Each condition to the Closing of the Merger Agreement
        set forth in Article VI thereof, other than conditions as to the
        consummation of the Contribution and the Distribution, shall have been
        fulfilled or waived by the party for whose benefit such condition
        exists.

                 (d)      The Board of Directors of GulfMark shall be
        reasonably satisfied that, after giving effect to the Contribution, (i)
        GulfMark will not be insolvent and will not have unreasonably small
        capital with which to engage in its businesses and (ii) the GulfMark
        surplus would be sufficient to permit, without violation of Section 170
        of the DGCL, the Distribution.

                                   ARTICLE IX

claims or controversies shall be decided by three independent arbitrators (that
is, arbitrators having no substantial economic or other material relationship
with the parties), one  to be appointed by Spinco and one to be appointed by
EVI within fourteen days following the submission of the claim to the parties
hereto and the third to be appointed by the two so appointed within five days.
Should either party refuse or neglect to join in the timely appointment of the
arbitrators, the other party shall be entitled to select both arbitrators.
Should the two arbitrators fail  timely to appoint a third arbitrator, either
party may apply to the Chief Judge of the United States





                                     - 19 -

District Court for the Southern District of Texas to make such appointment.
The arbitrators shall have ninety days after the selection of the third
arbitrator within which to allow discovery, hear evidence and issue their
decision or award and shall in good faith attempt to comply with such time
limits; provided, however, if two of the three arbitrators believe additional
time is necessary to reach a decision, they may notify the parties and extend
the time to reach a decision in thirty day increments, but in no event to
exceed an additional ninety days.  Discovery of evidence shall be conducted
expeditiously by the Parties, bearing in mind the parties desire to limit
discovery and to expedite the decision or award of the arbitrators at the most
reasonable cost and expense of the parties.  Judgment upon an award rendered
pursuant to such Arbitration may be entered in any court having jurisdiction,
or application may be made to such court for a judicial acceptance of the
award, and an order of enforcement, as the case may be. The place of
Arbitration shall be Houston, Texas.  The decision of the arbitrators, or a
majority thereof, made in writing, shall be final and binding upon the parties
hereto as to the questions submitted, and each party shall abide by such
decision.  Notwithstanding the provisions of this Section 9.2, neither party
shall be prohibited from seeking injunctive relief pending the completion of
any arbitration.  The costs and expenses of the arbitration proceeding,
including the fees of the arbitrators and all costs and expenses, including
legal fees and witness fees, incurred by the prevailing party, shall be borne
by the losing party.

        Solely for purposes of injunctive relief, orders in aid of arbitration
and entry of the arbitrator's award:

                 (a)      each of the parties hereto irrevocably consents to
        the non-exclusive jurisdiction of, and venue in, any state court
        located in Harris County, Texas or any federal court sitting in the
        Southern District of Texas in any suit, action or proceeding  seeking
        injunctive relief, arising out of or relating to this Agreement or any
        of the other agreements contemplated hereby and any other court in
        which a matter that may result in a claim for indemnification hereunder
        by an EVI Indemnified Party may be brought with respect to any claim
        for indemnification by an EVI Indemnified Party;

                 (b)      each of the parties hereto waives, to the fullest
        extent permitted by law, any objection that it may now or hereafter
        have to the laying of venue of any suit, action or proceeding seeking
        injunctive relief, orders in aid of arbitration or entry of an
        arbitration arising out of or relating to this Agreement or any of the
        other agreements contemplated hereby brought in any state court located
        in Harris County, Texas or any federal court sitting in the Southern
        District of Texas or any other court in which a matter that may result
        in a claim for indemnification hereunder by an EVI Indemnified Party
        may be brought with respect to any claim for indemnification by an EVI
        Indemnified Party, and further irrevocably waive any claim that any
        such suit, action or proceeding brought in any such court has been
        brought in an inconvenient forum;

                 (c)      each of the parties hereto irrevocably designates,
        appoints and empowers CT Corporation System, Inc. and any successor
        thereto as its designee, appointee and agent to receive, accept and
        acknowledge for and on its behalf, and in respect of its property,
        service of any and all legal process, summons, notices and documents
        which

        9.4      Entire Agreement.  This Agreement, including the Schedules,
Exhibits and other writings referred to herein or delivered pursuant hereto,
constitutes the entire agreement between the parties hereto with respect to the
subject matter hereof and supersedes all prior agreements and understandings,
both written and oral, between the parties with respect to the subject matter
hereof.

        9.5      Amendments and Waiver; Rights and Remedies.  This Agreement
may be amended, superseded, canceled, renewed or extended, and the terms hereof
may be waived, only by a written instrument signed by the parties or, in the
case of a waiver, by the party waiving compliance.  No delay on the part of
either party in exercising any right, power or privilege hereunder shall
operate as a waiver thereof, nor shall any waiver on the part of either party
of any such right, power or privilege, or any single or partial exercise of any
such right, power or privilege, preclude any further exercise thereof or the
exercise of any other such right, power or privilege.

        9.6      Governing Law.  The parties agree that the laws of the State
of Texas (without giving effect to the principles of conflicts of laws thereof)
shall govern the interpretation and enforcement of this Agreement and all
disputes arising under or in connection with this Agreement.

        9.7      Binding Effect; Assignment; No Third Party Benefit.

                 (a)      This Agreement and all the provisions hereof shall be
        binding upon and inure to the benefit of the parties and their
        respective successors and permitted assigns.

                 (b)      Nothing in this Agreement, express or implied, is
        intended to or shall confer upon any person other than Spinco,
        GulfMark, EVI, and the EVI Indemnified Parties any rights, benefits or
        remedies of any nature whatsoever under or by reason of this Agreement.

        9.8      Counterparts.  This Agreement may be executed simultaneously
in two or more counterparts, each of which shall be deemed an original, but all
of which together shall constitute one and the same agreement.

        9.9      References.  All references in this Agreement to Articles,
Sections and other subdivisions refer to the Articles, Sections and other
subdivisions of this Agreement unless expressly provided otherwise.  The words

similar import refer to this Agreement as a whole and not to any particular
subdivision unless expressly so limited.

        9.10     Severability of Provisions.  If any provision of this
Agreement is held to be unenforceable, this Agreement shall be considered
divisible and such provision shall be deemed inoperative to the extent it is
deemed unenforceable, and in all other respects this Agreement shall remain in
full force and effect; provided, however, that if any such provision may be
made





                                     - 22 -

enforceable by limitation thereof, then such provision shall be deemed to be so
limited and shall be enforceable to the maximum extent permitted by applicable
law.

        9.11     Gender.  Pronouns in masculine, feminine, and neuter genders
shall be construed to include any other gender, and words in the singular form
shall be construed to include the plural and vice versa, unless the context

United States dollars.

credit the amounts so received to the general deposit account of the Company
with the Agent or, if Loans are not made on such date because any condition
precedent to a Borrowing herein specified shall not have been met, return the
amounts so received to the respective Lenders as soon as practicable; provided,
however, if and to the extent the Agent fails to return any such amounts to a
Lender on the Borrowing Date for such Borrowing, the Agent shall pay interest
on such unreturned amounts, for each day from such Borrowing Date to the date
such amounts are returned to such Lender, at the Federal Funds Effective Rate.

                 (b)      Unless the Agent shall have been notified by any
Lender prior to the Borrowing Date that such Lender does not intend to make
available to the Agent such Lender's portion of the Borrowing to be made on
such date, the Agent may assume that such Lender has made such amount available
to the Agent on such date of Borrowing and the Agent may, in reliance upon such
assumption, make available to the Company a corresponding amount.  If such
corresponding amount is not in fact made available to the Agent by such Lender
by the required time on the Borrowing Date therefor and the Agent has made
available same to the Company, the Agent shall be entitled to recover such
corresponding amount on demand from such Lender.  If such Lender does not pay
such corresponding amount forthwith upon the Agent's demand therefor, the Agent
shall promptly notify the Company, and the Company shall pay such corresponding
amount to the Agent within two Business Days after demand therefor.  The Agent

may be, interest on such corresponding amount from the date such corresponding
amount was made available by the Agent to the Company to the date such
corresponding amount is recovered by the Agent, at a rate per annum equal to
(i) if paid by such Lender, the Federal Funds Effective Rate or (ii) if paid by
the Company (1) on or before the date that is two days after demand therefor,
the lesser of (A) the Highest Lawful Rate or (B) the sum of the Alternate Base
Rate or the LIBO Rate, as the case may be, in effect with respect to the Loans
made by the other Lenders comprising the remainder of the Borrowing, plus the
Margin then applicable to such Loans and (2) thereafter, the lesser of (A) the
Highest Lawful Rate or (B) the Default Rate in effect from time to time;
provided, that no such Loan shall bear interest pursuant to this clause (2) at
a rate





                                       41
<PAGE>   48
per annum less than the rate of interest applicable thereto pursuant to clause
(1) above.  Nothing herein shall be deemed to relieve any Lender from its
obligation to fulfill its commitments hereunder or to prejudice any rights
which the Company may have against any Lender as a result of any default by
such Lender hereunder.

                 SECTION 2.05.  Notes.  (a) The Company's obligation to pay the
principal of, and interest on, the Loans made by each Lender (including Loans
made pursuant to Section 3.03(b)) shall be evidenced by a promissory note duly
executed and delivered by the Company substantially in the form of Exhibit 2.05
hereto with blanks appropriately completed in conformity herewith (each a

                 (b)      Each Lender shall maintain in accordance with its
usual practice an account or accounts with respect to each Loan made by such
Lender hereunder, including the date, amount, Type and the Interest Period for
each Eurodollar Rate Loan made by such Lender to the Company hereunder, and the
amount of each payment in respect thereof and will, prior to any transfer of
either of its Notes, endorse on the reverse side thereof the outstanding
principal amount of Loans evidenced thereby.

                 (c)      The Agent shall maintain accounts in which it will
record (i) the amount of each Loan made hereunder, the Type and the Interest
Period for each Eurodollar Rate Loan made by each Lender, (ii) the amount of
any principal or interest due and payable or to become due and payable from the
Company to each Lender hereunder and (iii) the amount of any sum received by
the Agent hereunder from the Company and each Lender's share thereof.

                 (d)      Absent manifest error, the entries made in the
accounts maintained pursuant to paragraph (b) and (c) to this Section 2.05
shall be conclusive evidence of the existence and amounts of the obligations
therein recorded; provided, however, that the failure of any Lender or the
Agent to maintain such accounts or any error therein shall not in any manner
affect the obligations of the Company to repay the Loans and Drawings under the
Letters of Credit in accordance with their terms.

$3,000,000 ($1,000,000 in the case of conversions into Alternate Base Rate
Loans) of the outstanding principal amount of one Type of Loans made pursuant
to one or more Borrowings into a Borrowing or Borrowings of the other Type of
Loans provided, that (i) except as otherwise provided in Section 2.11, no
partial conversion of Eurodollar Rate Loans shall reduce the outstanding
principal amount of Eurodollar Rate Loans made pursuant to any single Borrowing
to less than $3,000,000, (ii) Alternate Base Rate Loans may only be converted
into Eurodollar Rate Loans, and Eurodollar Rate Loans may only be converted
into Eurodollar Rate Loans, if and only if, in either case, no Default or Event
of Default is in existence on the date of the conversion and (iii) no Loan may
be converted into a Eurodollar Rate Loan after the date that is one month prior
to the Stated Maturity Date.  Each such conversion shall be effected by the
Company giving the Agent notice (each a "Notice of Conversion") prior to 11:00
a.m. (New York City time) at least (a) three Business Days prior to the date of
such conversion in the case of a conversion into Eurodollar Rate Loans and (b)
one Business Day in the case of a conversion into Alternate Base Rate Loans,

proposed conversion affecting any of its Loans.

Agreement shall be incurred from the Lenders pro rata on the basis of their
respective Commitments.  It is understood that no Lender shall be responsible

commitments hereunder.

at all times be equal to the lesser of (i) the Highest Lawful Rate and (ii) the
applicable Margin plus the Alternate Base Rate, in each case, in effect from

the Base CD Rate or the Federal Funds Effective Rate, interest shall be
computed on the basis of the actual number of days elapsed over a year of 360
days.

                 (b)      Subject to Section 12.08, the Company agrees to pay
interest in respect of the unpaid principal amount of each Eurodollar Rate Loan
from the date of the respective Borrowing to the end of the Interest Period
therefor (unless such Loan is earlier accelerated or





                                       43
<PAGE>   50
converted pursuant to Section 2.06) at a rate per annum (computed on the basis
of the actual number of days elapsed over a year of 360 days) which shall,
during each Interest Period applicable thereto, be equal to the lesser of (i)
the Highest Lawful Rate and (ii) the applicable Margin plus the relevant LIBO
Rate for such Interest Period.  The applicable LIBO Rate shall be fixed for
each Interest Period and shall not change during said Interest Period but the
applicable Margin, which is added to the LIBO Rate to determine the total
interest payable to the Lender on each Eurodollar Rate Loan, shall be adjusted,
effective on the first day of each Reference Period, whether or not said
adjustment occurs at a time other than the beginning of an Interest Period.

                 (c)      Subject to Section 12.08, overdue principal and, to
the extent permitted by law, overdue interest in respect of each Loan and all
other overdue amounts owing hereunder shall bear interest for each day that
such amounts are overdue at a rate per annum equal to the lesser of (i) the
Highest Lawful Rate and (ii) 2% in excess of the sum of the applicable Margin
and the Alternate Base Rate, in each case, in effect from time to time (such
lesser rate of interest being the "Default Rate"); provided, that no Loan shall
bear interest after maturity (whether by acceleration or otherwise) at a rate
per annum less than the rate of interest applicable thereto at maturity.

                 (d)      Interest on the Loans made hereunder shall accrue
from the date of such Loan to the date of any repayment thereof and shall be
payable (i) in respect of Eurodollar Rate Loans (A) on the last day of the
Interest Period applicable thereto and also, in the case of any Interest Period
in excess of three months, on the date that would have been the last day of the
Interest Period if such Loan had an Interest Period of three months and (B) on
the date of any voluntary or mandatory prepayment or any conversion (on the
amount prepaid or converted), (ii) in respect of each Alternate Base Rate Loan
(A) on each Designated Payment Date and (B) on the date of any voluntary or
mandatory prepayment (on the amount prepaid) and (iii) in respect of each Loan,
at maturity (whether by acceleration or otherwise) and, after maturity, on
demand.

                 (e)      The Agent, upon determining the LIBO Rate for any
Interest Period, shall promptly notify by telephone (confirmed in writing) or
in writing the Company and the Lenders thereof.  Each such determination shall,
absent manifest error, be final and conclusive and binding on all parties
hereto.

                 SECTION 2.09.  Interest Periods.  (a) At the time the Company
gives any Notice of Borrowing or Notice of Conversion in respect of the making
of, or conversion into, a Eurodollar Rate Borrowing, the Company shall have the
right to elect, by giving notice to the Agent on the dates and at the times
specified in Section 2.03 or Section 2.06, as the case may be, of the selected
interest period (each an "Interest Period") applicable to such Eurodollar Rate





                                       44
<PAGE>   51
Borrowing, which Interest Period shall be either a one, two, three or six month
period; provided, that:

                 (i)      all Loans comprising a Eurodollar Rate Borrowing
         shall at all times have the same Interest Period;

                 (ii)     the initial Interest Period for any Eurodollar Rate
         Borrowing shall commence on the date of such Eurodollar Rate Borrowing
         (including the date of any conversion thereto pursuant to Section
         2.06) and each Interest Period occurring thereafter in respect of such
         Eurodollar Rate Borrowing shall commence on the day on which the next
         preceding Interest Period expires;

                 (iii)    if any Interest Period relating to a Eurodollar Rate
         Borrowing begins on a day for which there is no numerically
         corresponding day in the calendar month at the end of such Interest
         Period, such Interest Period shall end on the last Business Day of
         such calendar month;

                 (iv)     if any Interest Period would otherwise expire on a
         day which is not a Business Day, such Interest Period shall expire on
         the next succeeding Business Day; provided, however, that if any
         Interest Period in respect of a Eurodollar Rate Borrowing would
         otherwise expire on a day which is not a Business Day, but is a day of
         the month after which no further Business Day occurs in such month,
         such Interest Period shall expire on the next preceding Business Day;

                 (v)      no Interest Period shall extend beyond the Stated
         Maturity Date; and

                 (vi)     at no time shall there be more than ten Interest
         Periods in effect under this Agreement.

                 (b)      If upon the expiration of any Interest Period
applicable to a Eurodollar Rate Borrowing, the Company has failed to elect a
new Interest Period to be applicable to such Borrowing as provided above, the
Company shall be deemed to have elected to convert such Borrowing into a
Borrowing of Alternate Base Rate Loans effective as of the expiration date of
such current Interest Period.

                 SECTION 2.10.  Interest Rate Not Ascertainable, Etc.  In the
event that the Agent shall have determined (which determination shall be
reasonably exercised and shall, absent manifest error, be final, conclusive and
binding upon all parties) that on any date for determining the LIBO Rate for
any Interest Period, by reason of any changes arising after the date of this
Agreement affecting the interbank eurodollar market or any Lender's position in





                                       45
<PAGE>   52
such market, adequate and fair means do not exist for ascertaining the
applicable interest rate on the basis provided for in the definition of LIBO
Rate, then, and in any such event, the Agent shall forthwith give notice (by
telephone, confirmed in writing) to the Company and to the Lenders of such
determination.  Until the Agent notifies the Company that the circumstances
giving rise to the suspension described herein no longer exist, the obligations
of the Lenders to make Eurodollar Rate Loans shall be suspended; each requested
Eurodollar Rate Borrowing (by a Notice of Conversion or otherwise) shall
instead be made or maintained as a Borrowing of Alternate Base Rate Loans and
any outstanding Eurodollar Rate Loan shall be converted, on the last day of the
then applicable Interest Period, to an Alternate Base Rate Loan.

                 SECTION 2.11.  Reserve Requirements; Change in Circumstances.
(a) Notwithstanding any other provision herein, if, after the Execution Date,
the introduction or adoption of or any change (including any imposition or
increase of reserve requirements) in any Requirement of Law or in the
interpretation or application thereof or compliance by any Lender (or its
Applicable Lending Office) with any guideline, request or directive (whether or
not having the force of law) from any central bank or other Governmental
Authority exercising control over banks or financial institutions generally:

                 (i)      shall subject any Lender to any tax of any kind
         whatsoever with respect to this Agreement, any Note or any Eurodollar
         Rate Loan made by it, or change the basis of taxation of payments to
         such Lender in respect thereof (except for (i) Non-Excluded Taxes
         covered by Section 4.07 and (ii) changes in the rate of tax on the
         overall net income or revenue of such Lender or its Applicable Lending
         Office imposed by the jurisdiction in which the principal executive
         office of such Lender or its Applicable Lending Office is located); or

                 (ii)     shall impose, modify or hold applicable any reserve,
         special deposit, compulsory loan or similar requirement against assets
         of, deposits with or for the account of, or credit extended by, any
         Lender's Applicable Lending Office shall be imposed or deemed
         applicable or any other condition affecting its Eurodollar Rate Loans
         or its obligations to make Eurodollar Rate Loans shall be imposed on
         any Lender, its Applicable Lending Office or the interbank eurodollar
         market;

and as a result thereof there shall be any increase in the cost to such Lender
of agreeing to make or making, or funding or maintaining Eurodollar Rate Loans
or there shall be a reduction in the amount received or receivable by such
Lender or its Applicable Lending Office, then, in any such case, the Company
shall pay to the Agent for the account of such Lender such additional amount or
amounts as will compensate such Lender for such increased cost or reduced
amount to such Lender upon demand by such Lender (through the Agent).
Notwithstanding the foregoing, in no event shall the compensation payable under
this Section 2.11(a) (to the extent,





                                       46
<PAGE>   53
if any, constituting interest under applicable laws), together with all amounts
constituting interest under applicable laws and payable in connection with this
Agreement, the Notes and the other Loan Documents, exceed the Highest Lawful
Rate.

                 (b)      If any Lender shall have determined in good faith
that the adoption of or any change in any Requirement of Law regarding capital
adequacy or in the interpretation or application thereof or compliance by such
Lender or any corporation controlling such Lender with any request or directive
regarding capital adequacy (whether or not having the force of law) from any
Governmental Authority made subsequent to the Execution Date has or would have
the effect of reducing the rate of return on such Lender's or such
corporation's capital as a consequence of its obligations hereunder to a level
below that which such Lender or such corporation could have achieved but for
such adoption, change or compliance (taking into consideration such Lender's or
such corporation's policies with respect to capital adequacy) by an amount
deemed by such Lender to be material, then, from time to time, the Company
shall pay to the Agent for the account of such Lender such additional amount or
amounts as will compensate such Lender for such reduction by such Lender
(through the Agent).  Notwithstanding the foregoing, in no event shall the
compensation payable under this Section 2.11(b) (to the extent, if any,
constituting interest under applicable laws) together with all amounts
constituting interest under applicable laws and payable in connection with this
Agreement, the Notes or the other Loan Documents, exceed the Highest Lawful
Rate.

                 (c)      Each Lender will notify the Company through the Agent
of any event occurring after the Execution Date which will entitle such Lender
to compensation pursuant to this Section 2.11, as promptly as practicable, and
in any event within 120 days after it becomes aware thereof and determines to
request compensation.  A certificate of a Lender setting forth in reasonable
detail (i) such amount or amounts as shall be necessary to compensate such
Lender as specified in paragraph (a) or (b) above, as the case may be, and (ii)
the calculation of such amount or amounts under clause (a)(i), shall be
delivered to the Company (with a copy to the Agent) and shall be conclusive
absent manifest error.  The Company shall pay to the Agent for the account of
such Lender the amount shown as due on any such certificate within 10 days
after its receipt of the same. Upon the request of the Company, each Lender
agrees that it will use reasonable efforts to designate a different Applicable
Lending Office for the Loans due to it affected by the matters described in
Sections 2.11(a) and 2.11(b), if such designation will avoid or reduce the
liability of the Company to such Lender under this Section 2.11 so long as such
designation is not disadvantageous to such Lender as determined by such Lender
in its sole discretion.

                 (d)      Except as expressly provided in Section 2.11(c),
failure on the part of any Lender to demand compensation for any increased
costs or reduction in amounts received or receivable or reduction in return on
capital with respect to any Interest Period shall not constitute





                                       47
<PAGE>   54
a waiver of such Lender's rights to demand compensation for any increased costs
or reduction in amounts received or receivable or reduction in return on
capital with respect to such Interest Period or any other Interest Period.

                 (e)      In the event any Lender shall seek compensation
pursuant to this Section 2.11, the Company may give notice to such Lender (with
copies to the Agent) that it wishes to seek one or more Eligible Assignees to
assume the Commitments of such Lender and to purchase its outstanding Loans,
other Obligations and Notes.  Each Lender requesting compensation pursuant to
this Section 2.11 agrees to sell its Commitments, Loans, other Obligations,
Notes and interest in this Agreement and the other Loan Documents pursuant to
Section 12.11(c) to any Eligible Assignee for an amount equal to the sum of the
outstanding unpaid principal of and accrued interest on such Loans, such other
Obligations and Notes plus all other fees and amounts (including any
compensation claimed by such Lender under this Section 2.11, Section 2.13 and
Section 3.05) due such Lender hereunder calculated, in each case, to the date
such Commitments, Loans, other Obligations, Notes and interest are purchased,
whereupon such Lender shall have no further Commitment or other obligation to
the Company hereunder or under any Note.

                 SECTION 2.12.  Illegality.  (a) In the event that any Lender
shall have determined (which determination shall be reasonably exercised and
shall be presumptively correct) at any time that the making or continuance of
any Eurodollar Rate Loan has become unlawful by compliance by such Lender in
good faith with any Requirement of Law (whether or not having the force of law
and whether or not failure to comply therewith would be unlawful), then, in any
such event, the Lender shall give prompt notice (by telephone confirmed in
writing) to the Company and to the Agent of such determination.

                 (b)      Upon the giving of notice to the Company referred to
in Section 2.12(a) above, (i) the Company's right to request (by Notice of
Conversion or otherwise) and such Lender's obligation to make Eurodollar Rate
Loans shall be immediately suspended, and any such requested Eurodollar Rate
Borrowing shall instead be made as a Borrowing of Alternate Base Rate Loans,
and (ii) if the affected Eurodollar Rate Loan or Loans are then outstanding,
the Company shall immediately, or if permitted by applicable law, no later than
the date permitted thereby, upon at least one Business Day's notice to the
Agent and the affected Lender, convert each such Eurodollar Rate Loan into an
Alternate Base Rate Loan, provided that if more than one Lender is affected at
any time, then all affected Lenders must be treated the same pursuant to this
Section 2.12(b).

                 (c)      Each Lender agrees that it will use reasonable
efforts to designate a different Applicable Lending Office for the Eurodollar
Rate Loans due to it affected by this Section 2.12, if such designation will
avoid the illegality described in this Section 2.12 so long





                                       48
<PAGE>   55
as such designation will not be disadvantageous to such Lender as determined by
such Lender in its sole discretion.

                 (d)      For purposes of this Section 2.12, a notice to the
Company (with a copy to the Agent) by any Lender pursuant to paragraph (a)
above shall be effective on the date of receipt thereof by the Company.

                 (e)      In the event any Lender shall give a notice to the
Company pursuant to this Section 2.12, the Company may give notice to such
Lender (with copies to the Agent) that it wishes to seek one or more Eligible
Assignees to assume the Commitments of such Lender and to purchase its
outstanding Loans, Obligations and Notes.  Each Lender giving a notice to the
Company pursuant to this Section 2.12 agrees to sell its Commitments, Loans,
Obligations, Notes and interest in this Agreement and the other Loan Documents
pursuant to Section 12.11(c) to any such Eligible Assignee for an amount equal
to the sum of the outstanding unpaid principal of and accrued interest on such
Loans, Obligations and Notes plus all other fees and amounts (including any
compensation claimed by such Lender under Section 2.11, Section 2.13 and
Section 3.05) due such Lender hereunder calculated, in each case, to the date
such Commitment, Loans, Obligations, Notes and interest are purchased,
whereupon such Lender shall have no further Commitment or other obligation to
the Company hereunder or under any Note.

                 SECTION 2.13.  Indemnity.  The Company shall indemnify each
Lender against any loss (provided that any such loss with respect to
anticipated profits shall be limited as expressly provided in clauses (i) and
(ii) below) or reasonable expense which such Lender may sustain or incur as a
consequence of (a) any failure by the Company to fulfill on the date of any
Borrowing hereunder the applicable conditions set forth in Article V, (b) for
any reason, a Borrowing of or a conversion from or into Eurodollar Rate Loans
not occurring on the date specified therefor in a Notice of Borrowing or Notice
of Conversion, (c) any payment, prepayment or conversion of a Eurodollar Rate
Loan required by any other provision of this Agreement or otherwise made on a
date other than the last day of the applicable Interest Period, (d) any default
in the payment or prepayment of the principal amount of any Loan or any part
thereof or interest accrued thereon, as and when due and payable (at the due
date thereof, by notice of prepayment or otherwise) or (e) the occurrence of
any Event of Default, including, in the case of any of the events set forth in
clauses (a) through (d) of this Section 2.13, any loss or reasonable expense
sustained or incurred or to be sustained or incurred in liquidating or
employing deposits from third parties acquired to effect or maintain such Loan
or any part thereof as a Eurodollar Rate Loan.  Such loss or reasonable expense
shall include an amount equal to the excess, if any, as reasonably determined
by each Lender of (i) its cost of obtaining the funds for the Loan being paid,
prepaid or converted or not borrowed (based on the LIBO Rate) for the period
from the date of such payment, prepayment or conversion or failure to borrow to
the last day of the Interest Period for such Loan (or, in the case of a failure
to





                                       49
<PAGE>   56
borrow, the Interest Period for the Loan which would have commenced on the date
of such failure to borrow) over (ii) the amount of interest (as reasonably
determined by such Lender) that would be realized by such Lender in reemploying
the funds so paid, prepaid or converted or not borrowed for such period or
Interest Period, as the case may be.  Each Lender will notify the Company
through the Agent of any loss or expense which will entitle such Lender to
compensation pursuant to this Section 2.13, as promptly as possible and in any
event within 120 days after it becomes aware thereof and determines to accept
compensation.  A certificate of each Lender setting forth any amount or amounts
which such Lender is entitled to receive pursuant to this Section 2.13 shall be
delivered to the Company (with a copy to the Agent) and shall be conclusive, if
made in good faith, absent manifest error.  The Company shall pay to the Agent
for the account of each Lender the amount shown as due on any certificate
within 10 days after its receipt of the same.  Notwithstanding the foregoing,
in no event shall the compensation payable under this Section 2.13 (to the
extent, if any, constituting interest under applicable laws) together with all
amounts constituting interest under applicable laws and payable in connection
with this Agreement or the Notes, exceed the Highest Lawful Rate.  Without
prejudice to the survival of any other obligation of the Company hereunder, the
obligations of the Company under this Section 2.13 shall survive the
termination of this Agreement, the payment of the Obligations and the
assignment of any of the Notes.

                 SECTION 2.14.  Telephonic Notice.  Without in any way limiting
the Company's obligation to confirm in writing any telephonic notice it is
entitled to give under this Agreement, the Agent may act without liability upon
the basis of a telephonic notice believed in good faith by the Agent to be from
the Company prior to receipt of written confirmation.  In each such case, each
Loan Party hereby waives the right to dispute the Agent's record of the terms
of such telephonic notice.


                                  ARTICLE III

                               LETTERS OF CREDIT

                 SECTION 3.01.  Letters of Credit.  (a) Subject to and upon the
terms and conditions herein set forth, the Issuing Bank agrees that it will, at
any time and from time to time on or after the Effective Date and prior to the
date that is not later than 30 calendar days prior to the Stated Maturity Date,
following its receipt of a Letter of Credit Request and an Application, issue
for the account of the Company or the Company and any of the Restricted
Subsidiaries and in support of the obligations of the Company or any of the
Restricted Subsidiaries, one or more irrevocable letters of credit (all such
letters of credit collectively, the "Letters of Credit") up to a maximum not
exceeding the Letter of Credit Limit for all Letter of





                                       50
<PAGE>   57
Credit Outstandings, provided that the Issuing Bank shall be under no
obligation to issue any Letter of Credit if at the time of such issuance:

                 (i)      any order, judgment or decree of any Governmental
         Authority or arbitrator shall purport by its terms to enjoin or
         restrain the Issuing Bank from issuing such Letter of Credit or any
         Requirement of Law applicable to the Issuing Bank or any request or
         directive (whether or not having the force of law) from any
         Governmental Authority with jurisdiction over the Issuing Bank shall
         prohibit, or request that the Issuing Bank refrain from, the issuance
         of letters of credit generally; or

                 (ii)     if the Stated Amount of such Letter of Credit shall
         be greater than an amount which when added to the Letter of Credit
         Outstandings at such time and the aggregate principal amount of all
         Loans then outstanding (after giving effect to the principal amount of
         all Loans repaid and all Unpaid Drawings reimbursed prior to or
         concurrently with the issuance of such Letter of Credit), would exceed
         the lesser of (A) the Total Commitment (after giving effect to any
         reductions to the Total Commitment on such date) and (B) the Borrowing
         Base; or

                 (iii)    if the Stated Amount of such Letter of Credit shall
         be greater than an amount which when added to the Letter of Credit
         Outstandings at such time (after giving effect to all Unpaid Drawings
         reimbursed prior to or concurrently with the issuance of such Letter
         of Credit), would exceed the Letter of Credit Limit; or

                 (iv)     if the expiry date or, in the case of any Letter of
         Credit containing an expiry date that is extendible at the option of
         the Issuing Bank, the initial expiry date of such Letter of Credit is
         a date that is later than the date that is 30 calendar days prior to
         the Stated Maturity Date; or

                 (v)      if the proposed terms of any Letter of Credit would
         require the Issuing Bank to make any payment thereunder prior to the
         next Business Day after receipt of any documents or certificates to be
         presented under such Letter of Credit.

                 (b)      The Issuing Bank shall neither renew nor permit the
renewal of any Letter of Credit if any of the conditions precedent to such
renewal set forth in Section 5.02 are not satisfied or, after giving effect to
such renewal, the expiry date of such Letter of Credit would be a date that is
later than the date that is ten calendar days prior to the Stated Maturity
Date.

                 SECTION 3.02.  Letter of Credit Requests.  (a) Whenever the
Company desires that a Letter of Credit be issued or that the existing expiry
date of a Letter of Credit shall be extended, it shall give the Issuing Bank
(with copies to be sent to the Agent and each other





                                       51
<PAGE>   58
Lender) (i) in the case of a Letter of Credit to be issued, at least five
Business Days' prior written request therefor and (ii) in the case of the
extension of the existing expiry date of any Letter of Credit, at least five
Business Days prior to the date on which the Issuing Bank must notify the
beneficiary thereof that the Issuing Bank does not intend to extend such
existing expiry date.  Each such request shall be executed by the Company and
shall be in the form of Exhibit 3.02 attached hereto (each a "Letter of Credit
Request") and, in the case of the issuance of each Letter of Credit, shall be
accompanied by an Application therefor, completed to the satisfaction of the
Issuing Bank, and such other certificates, documents and other papers and
information as the Issuing Bank or any Lender (through the Agent) may
reasonably request.  Each Letter of Credit shall be denominated in Dollars or
any foreign currency agreed upon by the Issuing Bank and the Company, shall
expire no later than the date specified in Section 3.01, shall not be in an
amount greater than is permitted under clauses (ii) or (iii) of Section 3.01(a)
and shall be in such form or forms as may be approved from time to time by the
Issuing Bank and the Company.

                 (b)      The making of each Letter of Credit Request shall be
deemed to be a representation and warranty by the Company that such Letter of
Credit may be issued in accordance with, and will not violate the requirements
of, clauses (ii) or (iii) of Section 3.01(a).  Unless the Issuing Bank has
received notice from any Lender before it issues the respective Letter of
Credit or extends the existing expiry date of a Letter of Credit that one or
more of the conditions specified in Article V are not then satisfied, or that
the issuance of such Letter of Credit would violate this Agreement, then the
Issuing Bank shall issue the requested Letter of Credit for the account of the
Company in accordance with the Issuing Bank's usual and customary practices;
provided, however, that the Issuing Bank shall not be required to issue any
Letter of Credit earlier than three Business Days after its receipt of the
Letter of Credit Request and the related Application therefor and all other
certificates, documents and other papers and information relating thereto.
Upon its issuance of any Letter of Credit or the extension of the existing
expiry date of any Letter of Credit, as the case may be, the Issuing Bank shall
promptly notify the Company, the Agent and each Lender of such issuance or
extension, which notice shall be accompanied by a copy of the Letter of Credit
actually issued or a copy of any amendment extending the existing expiry date
of any Letter of Credit, as the case may be. For purposes of calculating the
amount of all Letters of Credit outstanding at any time, the amount of any
foreign currency denominated Letters of Credit shall be equal to that amount of
Dollars which could be purchased at such time with the amount of such foreign
currency denominated Letter of Credit.

                 (c)      Each Letter of Credit shall be governed by and
construed and interpreted under the UCP, and, as to matters not governed by the
UCP or that are required to be governed thereby, Article 5 of the Uniform
Commercial Code of the State of New York.

Immediately upon the issuance by the Issuing Bank of each Letter of Credit, the
Issuing Bank shall be deemed to have sold and transferred to each Lender, and
each Lender shall be deemed irrevocably and unconditionally to have purchased
and received from the Issuing Bank, without recourse or warranty, an undivided
interest and participation, to the extent of such Lender's Percentage
Participation in each such Letter of Credit (including extensions of the expiry
date thereof), each Letter of Credit issued in substitution therefor, each
Drawing made thereunder and the obligations of the Company or the Company and
any Restricted Subsidiary under this Agreement and the other Loan Documents
with respect thereto, and any security therefor or guaranty pertaining thereto
including the Guaranty.

                 (b)      In the event that the Issuing Bank makes any payment
under any Letter of Credit and the Company shall not have reimbursed such
amount in full to the Issuing Bank pursuant to Section 3.04(a), then, upon
demand by the Issuing Bank sent to the Agent and each Lender before 10:00 a.m.
(New York City time), each Lender shall pursuant to Section 2.04 on the same
day make available to the Agent for delivery to the Issuing Bank, immediately
available funds in an amount equal to such Lender's Percentage Participation of
the amount of such payment by the Issuing Bank, and the funding of such amount
shall be treated as the funding of a Loan by such Lender and shall bear
interest at the Alternate Base Rate.  Notwithstanding anything herein or in any
other Loan Document to the contrary, the funding obligations of the Lenders set
forth in this Section 3.03(b) shall be binding regardless of whether or not a
Default or an Event of Default shall exist or the other conditions precedent in
Article V are satisfied at such time. If and to the extent any Lender fails to
effect any payment due from it under this Section 3.03(b) to the Agent, then
interest shall accrue on the obligation of such Lender to make such payment
from and after the date such payment became due until such obligation is paid
in full at a rate per annum equal to the Federal Funds Effective Rate.  The
failure of any Lender to pay its Percentage Participation of any payment under
any Letter of Credit shall not relieve any other Lender of its obligation
hereunder to pay to the Agent its Percentage Participation of any payment under
any Letter of Credit on the date required, as specified above, but no Lender
shall be responsible for the failure of any other Lender to pay to the Agent
such other Lender's Percentage Participation of any such payment.

                 (c)      If the Issuing Bank receives a payment of a
reimbursement obligation from the Company as to which the Agent has received
any payments from the Lenders pursuant to clause (b) above, the Issuing Bank
shall pay to the Agent and the Agent shall promptly pay to each Lender which
has paid its Percentage Participation thereof, in Dollars and in same day
funds, an amount equal to such Lender's Percentage Participation thereof
together with any interest on such reimbursement obligation allocable to such
Lender's Percentage Participation paid by the Company to the Issuing Bank
pursuant to Section 3.04(a) and received by the Agent.

                 SECTION 3.04.  Agreement to Repay Letter of Credit Drawings.
(a) Upon  the receipt by the Issuing Bank of any demand for payment from a
beneficiary under a Letter of Credit (a "Drawing"), the Issuing Bank promptly
will provide the Agent, the Lenders and the Company with telecopy notice of
such demand.  The Company hereby agrees to reimburse the Issuing Bank by making
payment to the Agent in immediately available funds at the Payment Office, for
any payment (a "Drawing") made by the Issuing Bank under any Letter of Credit
(each such amount so paid until reimbursed, an "Unpaid Drawing") immediately
after, and in any event on the date of, such payment, with interest on the
amount so paid by the Issuing Bank, to the extent not reimbursed prior to 2:00
p.m. (New York City time) on the date of such payment, from and including the
date paid to but excluding the date reimbursement is made as provided above, at
a rate per annum equal to the Default Rate, payable on demand.

                 (b)      The Company's obligations under this Section 3.04 to
reimburse the Issuing Bank with respect to Unpaid Drawings (including, in each
case, interest thereon) shall, to the extent permitted by law, be absolute and
unconditional under any and all circumstances and irrespective of any setoff,
counterclaim or defense to payment which the Company may have or have had
against any Lender (including the Issuing Bank or any Lender as a participant
therein) or any beneficiary of a Letter of Credit, including (i) any lack of
validity or enforceability of this Agreement, such Letter of Credit or any
other Loan Document; (ii)  any adverse change in the condition (financial or
otherwise) of the Company or any of its Subsidiaries; (iii) any breach of this
Agreement or any other Loan Document by any Loan Party, the Agent or any Lender
(other than the Issuing Bank); (iv) the occurrence of any Default or Event of
Default; or (v) any non-application or misapplication by the beneficiary of the
proceeds of such Drawing.

                 (c)      The Company also agrees with the Issuing Bank and the
Lenders that the Issuing Bank shall not be responsible for, and the Company's
reimbursement obligations under Section 3.04(a) shall not be affected by, among
other things, (i) the validity or genuineness of documents or of any
endorsements thereon, even though such documents shall in fact prove to be
invalid, fraudulent or forged, or (ii) any dispute between or among the
Company, any other Loan Party and the beneficiary of any Letter of Credit or
any other party to which such Letter of Credit may be transferred or (iii) any
claims whatsoever of the Company or any other Loan Party against any
beneficiary of such Letter of Credit or any such transferee.

                 (d)      The Issuing Bank shall not be liable for any error,
omission, interruption or delay in transmission, dispatch or delivery of any
message or advice, however transmitted, in connection with any Letter of
Credit, except for errors or omissions caused by such Issuing Bank's gross
negligence or willful misconduct.  IT IS THE EXPRESS INTENTION OF THE PARTIES
HERETO THAT SUCH ISSUING BANK, ITS OFFICERS, DIRECTORS, EMPLOYEES AND AGENTS
(OTHER THAN WITH RESPECT TO ANY CLAIMS BY THE ISSUING BANK AGAINST ANY SUCH
OFFICER, DIRECTOR, EMPLOYEE OR





                                       54
<PAGE>   61
AGENT THEREOF) SHALL BE INDEMNIFIED AND HELD HARMLESS FROM ANY ACTION TAKEN OR
OMITTED BY SUCH PERSON UNDER OR IN CONNECTION WITH ANY LETTER OF CREDIT OR ANY
RELATED DRAFT OR DOCUMENT ARISING OUT OF OR RESULTING FROM SUCH PERSON'S SOLE
OR CONTRIBUTORY NEGLIGENCE, BUT NOT FROM THE GROSS NEGLIGENCE OR WILLFUL
MISCONDUCT OF SUCH PERSON.  The Company agrees that any action taken or omitted
by the Issuing Bank under or in connection with any Letter of Credit or the
related drafts or documents, if done in accordance with the standards of care
specified in the UCP and, as to any such actions not addressed by the UCP or
that are required to be taken thereunder, Article 5 of the Uniform Commercial
Code of the State of New York, shall not result in any liability of the Issuing
Bank to the Company or any other Person.

                 SECTION 3.05.  Increased Costs.  (a) Notwithstanding any other
provision herein, if any Lender shall have determined in good faith that any
change after the Execution Date of any Requirement of Law or the application or
effectiveness of any Requirement of Law or any change after the Execution Date
in the interpretation or administration thereof, or compliance by any Lender
(or any lending office of such Lender) or any corporation controlling such
Lender with any applicable guideline or request from any central bank or other
Governmental Authority (whether or not having the force of law) issued after
the Execution Date either (i) shall impose, modify or make applicable any
reserve, deposit, capital adequacy or similar requirement against Letters of
Credit issued, or participated in, by any Lender or (ii) shall impose on any
Lender any other conditions affecting this Agreement or any Letter of Credit;
and the result of any of the foregoing is to increase the cost to any Lender of
issuing, maintaining or participating in any Letter of Credit, or reduce the
amount received or receivable by any Lender or such corporation hereunder with
respect to Letters of Credit, by an amount deemed by such Lender to be
material, then, from time to time, the Company shall pay to the Agent for the
account of such Lender such additional amount or amounts as will compensate
such Lender for such increased cost or reduction by such Lender.

                 (b)      Each Lender will notify the Company through the Agent
of any event occurring after the date of this Agreement which will entitle such
Lender to compensation pursuant to subsection (a) above, as promptly as
practicable, and in any event within 120 days after it becomes aware thereof.
A certificate of a Lender (i) setting forth in reasonable detail such amount or
amounts as shall be necessary to compensate such Lender as specified in
subsection (a) above and (ii) the calculation of such amount or amounts under
subparagraph (a) may be delivered to the Company (with a copy to the Agent) and
shall be conclusive absent manifest error.  The Company shall pay to the Agent
for the account of such Lender the amount shown as due on any such certificate
within 10 days after its receipt of the same.

                 (c)      Except as expressly provided in Section 3.05(b),
failure on the part of any Lender to demand compensation for any increased
costs or reduction in amounts received or receivable or reduction in return on
capital with respect to any Letter of Credit shall not





                                       55
<PAGE>   62
constitute a waiver of such Lender's rights to demand compensation for any
increased costs or reduction in amounts received or receivable or reduction in
return on capital with respect to such Letter of Credit.

                 (d)      In the event any Lender shall seek compensation
pursuant to this Section 3.05, the Company may give notice to such Lender (with
copies to the Agent) that it wishes to seek one or more Eligible Assignees to
assume the Commitments of such Lender and to purchase its outstanding Loans,
other Obligations, Notes and interest in this Agreement and the other Loan
Documents.  Each Lender requesting compensation pursuant to this Section 3.05
agrees to sell its Commitments, Loans, other Obligations, Notes and interest in
this Agreement and other Loan Documents pursuant to Section 12.10(c) to any
such Eligible Assignee for an amount equal to the sum of the outstanding unpaid
principal of and accrued interest on such Loans, such other Obligations and
Notes (including any compensation claimed by such Lender under Section 2.11,
Section 2.13 and this Section 3.05) due such Lender hereunder calculated, in
each case, to the date such Commitments, Loans, other Obligations, Notes and
interest are purchased, whereupon such Lender shall have no further Commitment
or other obligation to the Company hereunder or under any Note.

                 SECTION 3.06.  Conflict between Applications and Agreement.
To the extent that any provision of any Application related to any Letter of
Credit is inconsistent with the provisions of this Agreement, the provisions of
this Agreement shall control.

                                   ARTICLE IV

                          FEES; COMMITMENTS; PAYMENTS

                 SECTION 4.01.  Fees.  (a) The Company agrees to pay the Agent
for the account of each Lender in arrears on each of the following dates:  (i)
each Designated Payment Date during the period from the Execution Date to the
date on which the Total Commitment is terminated and (ii) on the Stated
Maturity Date and on any other date on which the Commitment of any Lender is
terminated as provided herein a commitment fee (collectively the "Commitment
Fees") equal to the Applicable Fee Percentage on the daily average Unutilized
Commitment of each Lender.  The Commitment Fee due to each Lender shall
commence to accrue on the Execution Date and shall cease to accrue on the
earlier of the Stated Maturity Date or any other date on which the Commitment
of such Lender shall have been terminated as provided herein.

                 (b)      The Company agrees to pay the Agent for the account
of each Lender a fee in respect of each Letter of Credit issued for the account
of the Company or the Company and any Restricted Subsidiary (collectively, the
"Letter of Credit Fees"), for the period from the date of issuance of such
Letter of Credit to the expiry date of such Letter of Credit, computed 





                                       56
<PAGE>   63
at a rate equal to the Letter of Credit Margin times the daily average Stated
Amount of such Letter of Credit (but in no event less than $500).  The Letter of
Credit Fee shall be distributed to the Lenders (based upon their respective
Percentage Participations in the Letters of Credit). In addition, the Company
agrees to pay the Issuing Bank for its own account a fee in respect of each
Letter of Credit issued for the account of the Company or the Company and any
Restricted Subsidiary (collectively, the "Issuing Bank Fees") for the period
from the date of issuance of such Letter of Credit to the expiry date of such
Letter of Credit computed at a rate equal to 1/8 of 1% times the daily average
Stated Amount of such Letter of Credit.  Accrued Letter of Credit Fees and the
Issuing Bank Fees shall be due and payable in arrears on each Designated Payment
Date commencing December 31, 1996, and on the Stated Maturity Date or, if
earlier, on the date upon which the Commitment is terminated.  The Letter of
Credit Fees and the Issuing Bank Fees will be in lieu of all commissions and
fees for the Letters of Credit other than customary administrative, issuance,
amendment, payment and negotiation charges of the Issuing Bank.

                 (c)      The Company agrees to pay to the Agent, for its own
account, such Fees as have been agreed to pursuant to that certain letter
agreement dated as of June 26, 1996 between the Company and the Agent (the
"Agent's Letter").

                 (d)      All Fees pursuant to this Section 4.01 shall be paid
in immediately available funds and shall be calculated on the basis of the
actual number of days elapsed over a year of 360 days.

                 (e)      In no event shall the Fees payable to any Lender
under this Section 4.01 (to the extent, if any, constituting interest under
applicable laws) together with all amounts constituting interest under
applicable laws and payable in connection with this Agreement, the Notes and
other Loan Documents exceed the Highest Lawful Rate.

                 SECTION 4.02.  Voluntary Termination of Commitments.  Upon at
least five Business Days' prior telephonic notice confirmed in writing to the
Agent (which notice the Agent shall promptly transmit to each of the Lenders),
the Company shall have the right, without premium or penalty, to terminate the
Total Unutilized Commitment in part or in whole; provided, that any such
partial termination (a) shall apply proportionately to the Commitment of each
of the Lenders and (b) shall be in the amount of $5,000,000 or, if greater, an
integral multiple of $1,000,000.

                 SECTION 4.03.  Mandatory Termination of Commitments.  (a) The
Total Commitment shall terminate upon the occurrence of a Change of Control.

                 (b)      The Total Commitment, if not sooner terminated, shall
terminate on the Stated Maturity Date.

<PAGE>   64
                 SECTION 4.04.  Voluntary Prepayments.  The Company shall have
the right to voluntarily prepay the Loans in whole or in part from time to
time, without premium or penalty (except as provided below), on the following
terms and conditions: (a) the Company shall give the Agent at least three
Business Days' prior written or telephonic notice (if telephonic, promptly
confirmed in writing) of its intent to prepay the Loans, the principal amount
of such prepayment, the Type of Loans to be prepaid and the specific Borrowing
or Borrowings relating to such Loans, which notice the Agent shall promptly
transmit to each of the Lenders; (b) any Borrowing comprised of Eurodollar Rate
Loans may be prepaid prior to the last day of its Interest Period subject to
Section 2.13; (c) each partial prepayment of the Loans shall be in an aggregate
principal amount of $3,000,000.00 or, if greater, an integral multiple of
$1,000,000.00; and (d) each prepayment pursuant to this Section 4.04 shall be
applied, first, to the payment of accrued and unpaid interest, on the amount of
the Loans being so prepaid, and, second, to the outstanding principal of such
Loans.

                 SECTION 4.05.  Scheduled Principal Payments and Mandatory
Prepayments.  (a) On the date that a Change of Control of the type described in
clause (c) of the definition of that term occurs and on the date that is 15
days after the occurrence of any other type of Change of Control, the Company
shall prepay the outstanding principal amount of the Loans and shall deposit
with the Agent as security for the Letter of Credit Outstandings (i) with
respect to the Letters of Credit denominated in Dollars, Dollars in immediately
available funds in an amount equal to the aggregate Letter of Credit
Outstandings for such Letters of Credit and (ii) with respect to each Letter of
Credit denominated in a foreign currency, such foreign currency in immediately
available funds in an amount equal to the Letter of Credit Outstandings for
such Letter of Credit.

                 (b)      The Company shall prepay the outstanding principal
amount of the Loans on any day on which the aggregate outstanding principal
amount of the Loans, when added to Letter of Credit Outstandings, exceeds the
lesser of the Total Commitment and the Borrowing Base, in the amount of such
excess.  If, after giving effect to the prepayment of all outstanding Loans,
the Letter of Credit Outstandings exceed the lesser of the Total Commitment and
the Borrowing Base, the Company shall deposit with the Agent as security for
the Obligations, Dollars in immediately available funds in an amount equal to
such excess Letter of Credit Outstandings; provided, however, if any Letter of
Credit is denominated in a foreign currency, the deposit of funds with respect
to such Letter of Credit shall be in such foreign currency.

                 (c)      On the Stated Maturity Date, the Company shall pay
the aggregate principal amount of the Loans outstanding on such date.

                 (d)      All prepayments of Eurodollar Rate Loans required by
this Section 4.05 shall be subject to Section 2.13.





                                       58
<PAGE>   65
                 (e)      With respect to each prepayment of Loans required by
this Section 4.05, the Company may, consistent with the requirements of this
Section 4.05, designate the Types of Loans which are to be prepaid and, in the
case of Eurodollar Rate Loans, the specific Borrowing or Borrowings pursuant to
which made; provided, that if any prepayment of Eurodollar Rate Loans made
pursuant to a single Borrowing shall reduce the outstanding Loans made pursuant
to such Borrowing to an amount less than $3,000,000, such Borrowing shall
immediately be converted into Alternate Base Rate Loans.  In the absence of a
designation by the Company as described in the preceding sentence or in the
event such designation conflicts with the requirements of this Section 4.05,
the Agent shall, subject to the above and in accordance with this Section 4.05,
make such designation in its sole discretion.

                 SECTION 4.06.  Method and Place of Payment.  Except as
otherwise specifically provided herein, all payments under this Agreement and
the other Loan Documents shall be made to the Agent for the account of the
Lender or Lenders entitled thereto (without setoff, deduction or counterclaim
except as permitted in Section 4.07) not later than noon (New York City time)
on the date when due and shall be made in Dollars in immediately available
funds at the Payment Office.  If the Agent fails to send to any Lender its
portion of any Fee or of any payment of principal or interest (i) on the date
such Fee or payment of principal or interest was received if such Fee or
payment of principal or interest is received by the Agent prior to 1:00 p.m.
(New York City time) on such day and (ii) on the next succeeding Business Day
if such Fee or payment of principal or interest is received on or after 1:00
p.m. (New York City time) on any day, the Agent shall pay to such Lender
interest on its portion of such Fee or payment of principal or interest at the
Federal Funds Effective Rate from (A) the day such Fee or payment of principal
or interest was received by the Agent in the case of clause (i) and (B) such
next succeeding Business Day in the case of clause (ii), in each case, until
the date such Lender's portion of such Fee or payment of principal or interest
is sent to such Lender.  Except as otherwise expressly provided herein,
whenever any payment (including principal of or interest on any Borrowing or
any Fees or other amounts) to be made hereunder or under any other Loan
Document shall become due, or otherwise would occur, on a day that is not a
Business Day, such payment shall  be made on the next preceding Business Day.

                 SECTION 4.07.  Taxes.  (a) All payments made by the Loan
Parties under this Agreement, the Notes and the other Loan Documents shall be
made free and clear of, and without deduction or withholding for or on account
of, any present or future income, stamp or other taxes, levies, imposts,
duties, charges, fees, deductions or withholdings, now or hereafter imposed,
levied, collected, withheld or assessed by any Governmental Authority,
excluding net income taxes and franchise taxes (based on income) imposed on the
Agent or any Lender as a result of a present or former connection between the
Agent or such Lender and the jurisdiction of the Governmental Authority
imposing such tax or any political subdivision or taxing authority thereof or
therein.  If any such non-excluded taxes, levies, imposts, duties, charges,
fees,





                                       59
<PAGE>   66
deductions or withholdings ("Non-Excluded Taxes") are required to be withheld
from any amounts payable to the Agent or any Lender hereunder or under the
Notes, the amounts so payable to the Agent or such Lender shall be increased to
the extent necessary to yield to the Agent or such Lender (after payment of all
Non-Excluded Taxes) interest or any such other amounts payable hereunder at the
rates or in the amounts specified in this Agreement, the Notes and the other
Loan Documents; provided, however, that no Loan Party shall be required to
increase any such amounts payable to any Lender that is not organized under the
laws of the United States of America or a state thereof if such Lender fails to
comply with the requirements of paragraph (b) of this subsection.  The Agent
shall cooperate with any Loan Party in determining the appropriate amount
payable to any Lender or the Agent or the appropriate amount of withholding
taxes payable, to the extent reasonably required by any such Loan Party.
Whenever any Non-Excluded Taxes are payable by a Loan Party, as promptly as
possible thereafter such Loan Party shall send to the Agent for its own account
or for the account of such Lender, as the case may be, a certified copy of an
original official receipt received by such Loan Party showing payment thereof.
If a Loan Party fails to pay any Non-Excluded Taxes when due to the appropriate
taxing authority or fails to remit to the Agent the required receipts or other
required documentary evidence, the Loan Parties shall, subject to Section
12.08, indemnify the Agent and the Lenders for any incremental taxes, interest
or penalties that may become payable by the Agent or any Lender as a result of
any such failure.  The agreements in this subsection shall survive the
termination of this Agreement and the payment of the Notes and all other
amounts payable hereunder.

                 (b)      Each Lender that is not incorporated under the laws
of the United States of America or a state thereof shall:

                 (i)      deliver to the Company and the Agent (A) two duly
         completed copies of United States Internal Revenue Service Form 1001
         or 4224, or successor applicable form, as the case may be, and (B) an
         Internal Revenue Service Form W-8 or W-9, or successor applicable
         form, as the case may be;

                 (ii)     deliver to the Company and the Agent two further
         copies of any such form or certification on or before the date that
         any such form or certification expires or becomes obsolete and after
         the occurrence of any event requiring a change in the most recent form
         previously delivered by it to the Company; and

                 (iii)    obtain such extensions of time for filings and
         complete such forms or certifications as may reasonably be requested
         by the Company or the Agent;

unless in any such case an event (including any change in treaty, law or
regulation) has occurred prior to the date on which any such delivery would
otherwise be required which renders all such





                                       60
<PAGE>   67
forms inapplicable or which would prevent such Lender from duly completing and
delivering any such form with respect to it and such Lender so advises the
Company and the Agent.  Such Lender shall certify (i) in the case of a Form
1001 or 4224, that it is entitled to receive payments under this Agreement
without deduction or withholding of any United States federal income taxes and
(ii) in the case of a Form W-8 or W-9, that it is entitled to an exemption from
United States backup withholding tax.  Each Person that shall become a Lender
or purchases a participation pursuant to Section 12.11 shall, upon the
effectiveness of the related transfer, be required to provide all of the forms
and statements required pursuant to this subsection, provided that in the case
of any such participant, such participant shall furnish all such required forms
and statements to the Lender from which the related participation shall have
been purchased.

Except with respect to Loans made by the Lenders pursuant to Section 3.03(b),

                 SECTION 5.04.  Delivery of Documents.  All of the Notes,
certificates, legal opinions and other documents and papers referred to in this
Article V, unless otherwise specified, shall be delivered to the Agent for the
account of each of the Lenders and, except for the Notes, in sufficient
counterparts or copies for each of the Lenders and shall be satisfactory in

                                   ARTICLE VI

                         REPRESENTATIONS AND WARRANTIES

                 In order to induce the Lenders to enter into this Agreement
and to make the Loans provided for herein and to induce the Issuing Bank to
issue Letters of Credit and the other Lenders to participate therein, each Loan
Party makes, on or as of the Effective Date and the occurrence of each Credit
Event, the following representations and warranties to the Agent and the
Lenders:

                 SECTION 6.01.  Organization and Qualification.  The Company
and each of the Restricted Subsidiaries (a) is a corporation duly organized,
validly existing and in good standing under the laws of the state of its
incorporation or organization, (b) has the corporate, partnership or other
power to own its property and to carry on its business as now conducted and (c)
is duly qualified as a foreign corporation to do business and is in good
standing in every





                                       64
<PAGE>   71
 jurisdiction in which the failure to be so qualified would, individually or
together with all such other failures of the Loan Parties and their
Subsidiaries, have a Material Adverse Effect.  As of the Execution Date, the
corporations and other entities named in Schedule 6.01 are all of the
Subsidiaries of the Company, such Schedule (x) accurately reflects (i) the
direct owner of the Capital Stock of each such Subsidiary and (ii) the
percentage of the issued and outstanding Capital Stock of each such Subsidiary
owned by a Loan Party, (y) accurately identifies such Subsidiaries and (z)
accurately sets forth the jurisdictions of their respective incorporation or
organization and jurisdictions in which they are required to be qualified as
foreign corporations, foreign partnerships or other foreign entities to do
business.

                 SECTION 6.02.  Authorization, Validity, Etc.  Each Loan Party
has the corporate power and authority to execute, deliver and perform its
obligations hereunder and under the other Loan Documents to which it is a party
and, in the case of the Company, to make the Borrowings and obtain the issuance
of Letters of Credit hereunder, and all such action has been duly authorized by
all necessary corporate proceedings on its part.  This Agreement and the
Security Documents have been duly and validly executed and delivered by each
Loan Party party thereto and constitute valid and legally binding agreements of
such Loan Party enforceable against such Loan Party in accordance with the
respective terms thereof, and the Notes and the other Loan Documents to which
such Loan Party is a party, when duly executed and delivered by such Loan
Party, will constitute valid and legally binding obligations of such Loan Party
enforceable in accordance with the respective terms thereof and of this
Agreement, except, in each case, (a) as such enforceability may be limited by
bankruptcy, insolvency, reorganization, moratorium, fraudulent transfer or
other similar laws relating to or affecting the enforcement of creditors'
rights generally, and by general principles of equity which may limit the right
to obtain equitable remedies (regardless of whether such enforceability is a
proceeding in equity or at law) and (b) as to the enforceability of provisions
for indemnification for violation of applicable securities laws, limitations
thereon arising as a matter of law or public policy.

                 SECTION 6.03.  Governmental Consents, Etc.  No authorization,
consent, approval, license or exemption of or filing or registration with any
Governmental Authority, is necessary for the valid execution, delivery or
performance by any Loan Party of any Loan Document to which it is a party,
except those that have been obtained and such matters relating to performance
as would ordinarily be done in the ordinary course of business after the
Execution Date.

                 SECTION 6.04.  Conflicting or Adverse Agreements or
Restrictions.  Neither the Company nor any of the Restricted Subsidiaries is a
party to any contract or agreement or subject to any restriction that would
reasonably be expected to have a Material Adverse Effect.  Neither the
execution, delivery and performance by any Loan Party of the Loan Documents to
which it is a party, nor compliance with the terms and provisions thereof, nor
the extensions of





                                       65
<PAGE>   72
credit contemplated by the Loan Documents, (a) will breach or violate any
applicable Requirement of Law, (b) will result in any breach or violation of,
any of the terms, covenants, conditions or provisions of, or constitute a
default under, or result in the creation or imposition of (or the obligation to
create or impose) any Lien upon any of its property or assets pursuant to the
terms of any indenture, mortgage, deed of trust, agreement or other instrument
to which it or any of its Subsidiaries is party or by which any property or
asset of it or any of its Subsidiaries is bound or to which it is subject,
except for breaches, violations and defaults under clauses (a) and (b) that
collectively for all Loan Parties will not have a Material Adverse Effect or
(c) will violate any provision of the organic documents of any Loan Party.

                 SECTION 6.05.  Title to Assets.  Without limiting the
representations as to the Collateral contained in the Security Documents, the
Company and each Restricted Subsidiary has good and indefeasible title to its
assets constituting real property and good and indefeasible title to its other
assets, subject to no Liens, except Permitted Liens and immaterial Liens.

                 SECTION 6.06.  Litigation.  Except for the COLEVE tax matter
disclosed in its most recent filing on Form 10-K filed with the Securities and
Exchange Commission, there are no actions, suits or proceedings pending for
which service of process has been accomplished or, to the best knowledge of any
Loan Party, threatened with respect to any Loan Party, the Loan Documents or
any transactions contemplated therein that are reasonably likely to have
(individually or collectively) a Material Adverse Effect.

                 SECTION 6.07.  Information Memorandum; Financial Statements.
The Information Memorandum, as affected by the disclosures made herein, in the
other Loan Documents and in the filings made by the Company with the Securities
and Exchange Commission pursuant to the Exchange Act, did not as of the date
thereof and will not (in the case of the Information Memorandum) as of the date
of the initial Credit Event hereunder, contain any untrue statement of a
material fact or omit to state a material fact necessary in order to make the
statements contained therein not misleading in any material respect.  Since
December 31, 1995 there has been no material adverse change in the financial
condition, business or operations of the Company and the Restricted
Subsidiaries taken as a whole.

                 SECTION 6.08.  Default.  Except for defaults or violations
which, individually or together with all other defaults and violations by the
Company and the Restricted Subsidiaries, would not reasonably be expected to
have a Material Adverse Effect, neither the Company nor any Restricted
Subsidiary is in default in any respect under the provisions of any instrument
evidencing any Indebtedness or of any agreement relating thereto, or in default
in any respect under or in violation of any Requirement of Law.





                                       66
<PAGE>   73
                 SECTION 6.09.  Investment Company Act.  Neither the Company
nor any of its Subsidiaries is, or is regulated as an "investment company," as
such term is defined in the Investment Company Act of 1940, as amended.

                 SECTION 6.10.  Public Utility Holding Company Act.  Neither
the Company nor any of its Subsidiaries is a non-exempt "holding company," or
subject to regulation as such, or, to the knowledge of any Loan Party's
officers, an "affiliate" of a "holding company" or a "subsidiary company" of a
"holding company," within the meaning of the Public Utility Holding Company Act
of 1935, as amended.

                 SECTION 6.11.  ERISA.  (a) The Company and each ERISA
Affiliate has operated and administered each Plan and Multiemployee Plan in
compliance with all applicable laws except for such instances of noncompliance
as have not resulted in and would not reasonably be expected to have a Material
Adverse Effect.  Neither the Company nor any ERISA Affiliate has incurred any
liability pursuant to Title I or IV of ERISA or the penalty or excise tax
provisions of the Code relating to employee benefit plans (as defined in
Section 3 of ERISA), and no event, transaction or condition has occurred or
exists that would reasonably be expected to result in the incurrence of any
such liability by the Company or any ERISA Affiliate, or in the imposition of
any Lien on any of the rights, properties or assets of the Company or any ERISA
Affiliate, in either case pursuant to Title I or IV of ERISA or to such penalty
or excise tax provisions or to Section 401(a)(29) or 412 of the Code, other
than such liabilities or Liens as would not individually or in the aggregate
reasonably be expected to have a Material Adverse Effect.

                 (b)       No accumulated funding deficiency (as defined in
Section 412 of the Code or Section 302 of ERISA) in excess of $1,000,000,
whether or not waived, exists or is expected to be incurred with respect to any
Plan.

                 (c)      The Company and its ERISA Affiliates have not
incurred withdrawal liabilities  (and are not subject to contingent withdrawal
liabilities) under section 4201 or 4204 of ERISA in respect of Multiemployer
Plans that individually or in the aggregate would reasonably be expected to
have a Material Adverse Effect.

                 (d)      The expected post-retirement benefit obligation
(determined as of the last day of the Company's most recently ended fiscal year
in accordance with Financial Accounting Standards Board Statement No. 106,
without regard to liabilities attributable to continuation coverage mandated by
section 4980B of the Code) of the Company and the Restricted Subsidiaries would
not  reasonably be expected to have a Material Adverse Effect.





                                       67
<PAGE>   74
                 (e)      No such Multiemployer Plan is in "reorganization" or
"insolvent," within the meaning of such terms as used in ERISA.

                 SECTION 6.12.  Tax Returns and Payments.  (a) The Company and
its Subsidiaries have caused to be filed all federal income tax returns and
other material tax returns, statements and reports (or obtained extensions with
respect thereto) which are required to be filed and have paid or deposited or
made adequate provision in accordance with GAAP for the payment of all taxes
(including estimated taxes shown on such returns, statements and reports) which
are shown to be due pursuant to such returns, except where the failure to pay
such taxes (individually or collectively for the Company and the Restricted
Subsidiaries) would not have a Material Adverse Effect.  No material income tax
liability of the Company or the Restricted Subsidiaries has been asserted by
the Internal Revenue Service of the United States or any other Governmental
Authority for any taxes in excess of those already paid, except for taxes which
are being contested in good faith by appropriate proceedings and for which
adequate reserves in accordance with GAAP have been created on the books of the
Company and the Restricted Subsidiaries.

                 (b)      The federal income tax liabilities, if any, of the
Company and its Subsidiaries have been finally determined by the Internal
Revenue Service and satisfied for all taxable years through the fiscal year
ending in 1992.  COLEVE, a dissolved partnership in which the Company held less
than a 50% interest, has open tax years for the fiscal years ending in 1985
through 1990.

                 SECTION 6.13.  Requirements of Law; Environmental Matters.
(a) The Company and each Restricted Subsidiary is in compliance with all
Requirements of Law, applicable statutes, regulations and orders of, and all
applicable restrictions imposed by, all Governmental Authorities in respect of
the conduct of its business and the ownership  of its property, except for such
noncompliances which, individually or in the aggregate for the Company and all
such Restricted Subsidiaries, would not have a Material Adverse Effect.

                 (b)      Without limitation of the foregoing, the Company and
each Restricted Subsidiary possesses all environmental, health and safety
licenses, permits, authorizations, registrations, approvals and similar rights
necessary under law or otherwise for the Company or such Restricted Subsidiary
to conduct its operations as now being conducted (other than those with respect
to which the failure to possess or maintain would not, individually or in the
aggregate for the Company and all such Restricted Subsidiaries, have a Material
Adverse Effect), and each of such licenses, permits, authorizations,
registrations, approvals





                                       68
<PAGE>   75
and similar rights is valid and subsisting, in full force and effect and
enforceable by the Company or such Restricted Subsidiary, and the Company and
each Restricted Subsidiary is in compliance with all terms, conditions or other
provisions of such permits, authorizations, registrations, approvals and
similar rights except for such failure or noncompliance that, individually or
in the aggregate for the Company and all such Restricted Subsidiaries, would
not have a Material Adverse Effect.  Except as disclosed on Schedule 6.13,
neither the Company nor any Restricted Subsidiary has received any notices of
any violation of, noncompliance with, or remedial obligation under,
Requirements of Environmental Laws, and there are no writs, injunctions,
decrees, orders or judgments outstanding, or lawsuits, claims, proceedings,
investigations or inquiries or, to the knowledge of any Loan Party, pending or
threatened, relating to the ownership, use, condition, maintenance or operation
of, or conduct of business related to, any property owned, leased or operated
by the Company or any Restricted Subsidiary or other assets of the Company or
such Restricted Subsidiary, other than those violations, instances of
noncompliance, obligations, writs, injunctions, decrees, orders, judgments,
lawsuits, claims, proceedings, investigations or inquiries that, individually
or in the aggregate for all Loan Parties and such Subsidiaries, would not have
a Material Adverse Effect.  Except as disclosed on Schedule 6.13, there are no
material obligations, undertakings or liabilities arising out of or relating to
Environmental Laws to which any Loan Party or any of its Subsidiaries has
agreed, assumed or retained, or by which any Loan Party or any of its
Subsidiaries is adversely affected, by contract or otherwise, which would have
a Material Adverse Effect.  Except as disclosed on Schedule 6.13, no Loan Party
nor any of its Subsidiaries has received a written notice or claim to the
effect that such Person is or may be liable to any other Person as the result
of a Release or threatened Release of a Hazardous Material, which liability
would have a Material Adverse Effect.

                 SECTION 6.14.  Purpose of Loans.  (a) The purpose of the Loans
is to provide working capital facilities to the Company and the Restricted
Subsidiaries.  All proceeds of the Loans will be used by the Company for
working capital or advanced to a Restricted Subsidiary for use by such
Restricted Subsidiary for working capital.  All Letters of Credit will be
issued in connection with the working capital requirements of the Company or a
Restricted Subsidiary.

                 (b)      None of the proceeds of the Loans under the Original
Credit Agreement or this Agreement were or will be used directly or indirectly
for the purpose of buying or carrying any "margin stock" within the meaning of
Regulation U (herein called "margin stock") or for the purpose of reducing or
retiring any indebtedness (including the indebtedness repaid with the proceeds
of the loans made under the Original Credit Agreement) which was originally
incurred to buy or carry a margin stock, or for any other purpose which might
constitute this transaction a "purpose" credit within the meaning of Regulation
U.  Neither any Loan Party nor any agent acting on its behalf has taken or will
take any action which might cause this Agreement or any other Loan Document to
violate Regulation U, Regulation X, or any other regulation of the Board or to
violate the Securities Exchange Act of 1934.  Margin stock did not on June 26,
1996, and does not on the date hereof constitute more than 25% of the assets of
the Company or any Loan Party.





                                       69
<PAGE>   76
                 SECTION 6.15.  Franchises and Other Rights.  The Company and
each Restricted Subsidiary has all franchises, permits, licenses and other
authority (collectively, the "Operating Rights") as are necessary to enable
them to carry on their respective businesses as now being conducted, except for
Operating Rights with respect to which the failure to have would not
individually or in the aggregate for all such failures by the Company and the
Restricted Subsidiaries have a Material Adverse Effect.  Neither the Company
nor any Restricted Subsidiary is in default under any of the Operating Rights
which default, individually or together with all such defaults of the Company
and the Restricted Subsidiaries, would have a Material Adverse Effect.

                 SECTION 6.16.  Solvency.  Each Loan Party is Solvent.

                 For purposes of this Section 6.16 the term "Solvent" shall
mean, with respect to any Person, that:

                 (a)      the assets of such Person, at a fair valuation,
exceed the total liabilities (including contingent, subordinated, unmatured and
unliquidated liabilities) of such Person;

                 (b)      based on current projections, which are based on
underlying assumptions which provide a reasonable basis for the projections and
which reflect such Person's judgment based on present circumstances, of the
most likely set of conditions and such Person's most likely course of action
for the period projected, such Person believes it has sufficient cash flow to
enable it to pay its debts as they mature; and

                 (c)      such Person does not have unreasonably small capital
with which to engage in its anticipated business.

                 For purposes of this Section 6.16, the "fair valuation" of the
assets of any Person shall be determined on the basis of the amount which may
be realized within a reasonable time, either through collection or sale of such
assets at the regular market value, conceiving the latter as the amount which
could be obtained for the property in question within such period by a capable
and diligent businessman from an interested buyer who is willing to purchase
under ordinary selling conditions, including obtaining necessary consents.

                 SECTION 6.17.  No Intent to Hinder, Delay or Defraud.  Each
Subsidiary Guarantor  has entered into this Agreement, including the Guaranty
and the other Loan Documents, with no intent to hinder, delay or defraud any
Person to whom such Subsidiary Guarantor was or becomes, on or after the
Execution Date, indebted, within the meaning of Section 548 of the Bankruptcy
Code.

<PAGE>   77
                 SECTION 6.18.  Further Actions.  The Loan Parties will make
all reasonable efforts to cause the Agent to have a perfected security interest
in the equity of Producion Engemaq Industria E Comercio Ltda.

                                  ARTICLE VII

                             AFFIRMATIVE COVENANTS

                 Each Loan Party covenants and agrees for itself, and the
Company covenants and agrees with respect to each of the Restricted
Subsidiaries, that on and after the date hereof and for so long as this
Agreement is in effect and until the Commitments and each Letter of Credit have
terminated, and the Loans and Unpaid Drawings together with all of the other
Obligations are paid in full:

                 SECTION 7.01.  Information Covenants.  The Company will
furnish or cause to be furnished to the Agent and each Lender:

                 (a)      As soon as available, and in any event within 60 days
after the end of each of the first three quarterly accounting periods in each
fiscal year (i) the Form 10-Q of the Company and (ii) the consolidated balance
sheet of the Company and its Subsidiaries as at the end of such fiscal quarter
and the related consolidated unaudited statement of income and cash flows for
such fiscal quarter and for the elapsed portion of the fiscal year ended with
the last day of such fiscal quarter, and setting forth, in each case,
comparative consolidated figures for the related periods in the prior fiscal
year, all of which shall be certified by the chief financial officer, chief
executive officer or controller of the Company subject to note changes
resulting from normal year-end audit adjustments; provided, however, if the
Form 10-Q of the Company contains the consolidated balance sheet and statements
of income, retained earnings and cash flows, the Company shall not be required
to comply with clause (ii).

                 (b)      As soon as available, and in any event within 120
days after the close of each fiscal year, the Annual Report of the Company for
such fiscal year containing therein, the consolidated balance sheet of the
Company and its Subsidiaries as at the end of such fiscal year and the related
consolidated statements of income, retained earnings and cash flows for such
fiscal year, setting forth, in each case, comparative figures for the preceding
fiscal year and certified by Arthur Andersen LLP or other independent certified
public accountants of recognized national standing reasonably acceptable to the
Agent and the Majority Lenders, whose certification shall be without
Impermissible Qualification together with a certificate of such accounting firm
stating that in the course of its regular audit of the business of the Company,
which audit was conducted in accordance with generally accepted United States

year, an annual business plan and budget for the Company and the Restricted
Subsidiaries for the next succeeding fiscal year containing, inter alia, pro
forma financial statements for the next fiscal year.

                 (l)      From time to time and with reasonable promptness,
such other information or documents (financial or otherwise with respect to the
Company or any Restricted Subsidiary) as the Agent or any Lender through the
Agent may reasonably request.

                 SECTION 7.02.  Books, Records and Inspections.  Each Loan
Party will permit, or cause to be permitted, any Person designated by any
Lender or the Lenders in writing to visit and inspect any of the properties of
the Company and the Restricted Subsidiaries, to examine the corporate books and
financial records of the Company and the Restricted Subsidiaries and make
copies thereof or extracts therefrom and to discuss the affairs, finances and
accounts of any such corporations with the officers and agents of the Company
and the Restricted Subsidiaries and with their independent public accountants,
all at such reasonable times and as often as the Agent or such Lender, through
the Agent, may reasonably request.  Upon the occurrence and during the
continuance of an Event of Default, any Person designated





                                       74
<PAGE>   81
by the Agent may request that such independent public accountants obtain
confirmation reports from account and chattel paper obligors of the Company and
its Subsidiaries. The Agent or its representatives may at the Company's
reasonable expense conduct an annual field exam to verify the Borrowing Base
components; provided that the field exam shall not include any communication to
or contact with any account debtor.

                 SECTION 7.03.  Insurance and Maintenance of Properties.  (a)
The Loan Parties will maintain or cause to be maintained, with financially
sound and reputable insurers, insurance with respect to its property and
business against such liabilities, casualties, risks and contingencies
(including business interruption insurance) and in such types and amounts as is
customary in the case of Persons engaged in the same or similar businesses and
similarly situated, provided that, unless such coverage is not available at
commercially reasonable rates for reasons other than the acts or omissions of
the Loan Parties, in no event shall the coverage and amount of such insurance
be less than the coverage and amount of the insurance which, in the opinion of
an independent insurance broker (the "Insurance Opinion") delivered on June 26,
1996, is adequate and customary for the Loan Parties taking into account the
Loan Parties' historical loss experience.  All policies of insurance required
by the terms of this Agreement or any Security Document shall provide that at
least 20 days' prior written notice be given to the Agent of any termination,
cancellation, reduction or other material modification of such insurance, shall
contain an endorsement or agreement by the insurer that any loss shall be
payable in accordance with the terms of such policy notwithstanding any act or
negligence of any Loan Party, or any party holding under such Loan Party, which
might otherwise result in forfeiture of said insurance and shall contain the
agreement of the insurer waiving all rights of setoff, counterclaim or
deductions against such Loan Party.  Notwithstanding the foregoing, the
insurance coverage of the Loan Parties on the date hereof complies with the
requirements of the foregoing sentence.  The Loan Parties shall furnish or
cause to be furnished to the Agent (i) not later than April 30 in each year (A)
a certificate from an independent insurance broker demonstrating the Loan
Parties' compliance with this paragraph (a) and (B) a summary of all insurance
coverage of the Loan Parties prepared by an independent insurance broker, (ii)
upon request of the Agent, copies of all policies of insurance and (iii) as
soon as any Loan Party becomes aware thereof, a notification from such Loan
Party of any material change in the coverage or any other condition of any
policy of insurance required by this Section 7.03.  The Agent, for the benefit
of the Lenders, shall be named as a loss payee as its interest may appear on
all such fire, accident and other casualty policies covering any of the
Collateral.

                 (b)      In addition to any requirements as to the maintenance
of the Collateral contained in the Security Documents, the Company will, and
will cause the Restricted Subsidiaries to, cause all properties owned by the
Company or any Restricted Subsidiary or used or held for use in the conduct of
the business of the Company or the business of any such Restricted Subsidiary
to be maintained and kept in good condition, repair and working order and





                                       75
<PAGE>   82
supplied with all necessary equipment and will cause to be made all necessary
repairs, renewals, replacements, betterments and improvements thereof, all as
in the judgment of the Company may be necessary so that the business carried on
in connection therewith may be properly and advantageously conducted at all
times; provided, however, that nothing in this Section 7.03(b) shall prevent
the Company from discontinuing the maintenance of any of such properties if
such discontinuance is, in the judgment of the Company, desirable in the
conduct of its business or the business of any such Restricted Subsidiary and
not disadvantageous in any material respect to the Lenders.

                 SECTION 7.04.  Payment of Taxes and other Claims. The Company
will, and will cause each of the Restricted Subsidiaries to, pay or discharge
or cause to be paid or discharged, before the same shall become delinquent, (a)
all taxes, assessments and governmental charges levied or imposed upon the
Company or such Restricted Subsidiary or upon the income, profits or property
of the Company or such Restricted Subsidiary and (b) all lawful claims for
labor, materials and supplies which, if unpaid, might by law become a Lien upon
the property of the Company or such Restricted Subsidiary; provided, however,
(i) that the Company and the Restricted Subsidiaries shall not be required to
pay or discharge or cause to be paid or discharged any such tax, assessment,
charge or claim whose amount, applicability or validity is being contested in
good faith by appropriate proceedings, (ii) has not been reported, so long as
the position taken by such Loan Party or such Subsidiary in not reporting same
is based on "substantial authority," as defined in Section 6661 of the Code or,
in the case of taxes other than U.S. federal income taxes, upon the reasonable
judgment of such Loan Party after consultation with tax counsel and so long as,
if any such item is challenged, it is paid or the requirements of the preceding
clause (i) are met with respect thereto, but in either case only if it has
maintained adequate reserves with respect thereto in accordance with GAAP, or
(iii) with respect to foreign Restricted Subsidiaries, if such taxes,
assessments, charges or levies are not material to the financial condition or
operation of such foreign Restricted Subsidiaries or have not been levied by a
bona fide Governmental Authority.

                 SECTION 7.05.  Existence.  Except as expressly permitted
pursuant to Section 8.02, each Loan Party will do all things necessary to
preserve and keep in full force and effect the corporate, partnership or other
existence, rights and franchises of such Loan Party and each Restricted
Subsidiary.

                 SECTION 7.06.  Compliance with Statutes, Etc.  (a) The Company
will and will cause each Restricted Subsidiary to comply with each applicable
Requirement of Law, other than those Requirements of Law, the failure to comply
with which (individually or collectively for the Company and the Restricted
Subsidiaries) would not have a Material Adverse Effect; provided, however, the
Company and each such Restricted Subsidiary shall have the right to diligently
contest any Requirement of Law; so long as (i) the contest is in good faith and
by





                                       76
<PAGE>   83
appropriate proceedings and such reserve or other appropriate provision, in
any, as shall be required by GAAP shall have been made therefor, (ii) such
contest shall operate to suspend the collection of any disputed amount from
such property and (iii) such contest will not (A) subject any or any part of
such property to loss, forfeiture or sale or (B) adversely affect the Lien of
the Security Documents or (C) have a Material Adverse Effect.

                 (b)      Without limiting the foregoing, the Company will and
will cause each  Restricted Subsidiary (i) to  comply in a timely fashion with,
or operate pursuant to valid waiver of the provisions of, all Requirements of
Environmental Laws, including any such laws or regulations relating to
contamination from any Hazardous Materials, except where noncompliance would
not have a Material Adverse Effect, and (ii) to produce all inventory which is
manufactured in the United States in compliance in all material respects with
the Fair Labor Standards Act.

                 SECTION 7.07.  ERISA.  As soon as possible and, in any event,
within ten Business Days after any Responsible Officer of any Loan Party knows
or has reason to know any of the following, such Loan Party will deliver or
cause to be delivered to each of the Lenders a certificate of the chief
financial officer of the Company setting forth details as to such occurrence
and such action, if any, which the Loan Party or its ERISA Affiliate is
required or proposes to take, together with any notices required or proposed to
be given to or filed with or by such Loan Party or ERISA Affiliate with respect
thereto:  that a Reportable Event has occurred; that an application may be or
has been made to the Secretary of the Treasury for a waiver or modification of
the minimum funding standard (including any required installment payments) or
an extension of any amortization period under Section 412 of the Code with
respect to a Plan; that the aggregate amount of Unfunded Current Liabilities
with respect to one or more Plans exceeds $1,000,000; that a Multiemployer Plan
has been or may be terminated, reorganized, partitioned or declared insolvent
under Title IV of ERISA; that any required contribution to a Plan or
Multiemployer Plan has not been or may not be timely made; that proceedings may
be or have been instituted under Section 4069(a) of ERISA to impose liability
on a Loan Party or an ERISA Affiliate or under Section 4042 of ERISA to
terminate a Plan or appoint a trustee to administer a Plan; that a Loan Party
or any ERISA Affiliate has incurred or may incur any liability (including any
contingent or secondary liability) on account of the termination of or
withdrawal from a Plan or a Multiemployer Plan under Section 4062, 4063, 4064,
4201 or 4204 of ERISA, which liability together with all other such liabilities
exceeds $1,000,000; that the Company or an ERISA Affiliate may be required to
provide security to a Plan under Section 401(a)(29) of the Code; or any other
condition(s) exist(s) or may occur with respect to one or more Plans and/or
Multiemployer Plans which (individually or collectively) is reasonably likely
to result in the imposition of a material excise tax(es), penalty(ies) or other
material liability(ies) on the Company and/or any ERISA Affiliate.

                 SECTION 7.08.  End of Fiscal Years.  The Company shall cause
each of its, and each domestic Restricted Subsidiary's fiscal years to end on
December 31 and with respect to Restricted Subsidiaries acquired by the Company
after the date hereof, will cause such change to December 31 to occur as
promptly as possible.

                 SECTION 7.09   Subrogation; Purchase Money Liens.  To the
extent that the Agent pays any sum under any provision of law or any instrument
or document creating any Lien prior or superior to the Lien of any Security
Document, or any such sum is paid with the proceeds of the issuance of the
Notes, then, to the extent permitted by law, the Agent for the benefit of the
Lenders shall have and be entitled to a Lien on the Collateral equal in
priority to the Lien discharged, and the Agent for the benefit of the Lenders
shall be subrogated to, and receive and enjoy all rights and Liens possessed,
held or enjoyed by, any owner or holder of such Lien, which shall remain in
existence and benefit the Agent for the benefit of the Lenders in securing the
obligations secured by the Security Documents, irrespective of whether such
Liens are released.

                 SECTION 7.10.  Performance of Loan Documents.  (a) Each Loan
Party will duly and punctually pay and perform its respective obligations under
the Loan Documents to which it is a party in accordance with, and without
breach of, the terms of each thereof.

                 (b)      If any Loan Party fails to pay any tax, assessment,
standby fee, insurance premium or other charge, cost or expense called for
herein or in any of the other Loan Documents, the Agent may, at the request of
the Majority Lenders, pay the same, or if any Loan Party fails to perform any
of the Loan Party's covenants or agreements, or breaches any of such Loan
Party's warranties and representations, set forth herein or in any of the other
Loan Documents, the Agent may, at the request of the Majority Lenders, correct
or cure, or cause to be corrected and cured, the default or breach and pay such
sums in connection therewith as the Majority Lenders shall determine to be
necessary or advisable, and all taxes, assessments, standby fees, charges,
insurance premiums and other sums paid by the Agent in connection with such
matters shall be immediately repayable by the Loan Parties to the Agent,
together with interest on each such amount at the Default Rate from the date
the sum is paid by the Agent, until the same is refunded to the Agent, and all
such amounts and the interest thereon shall be secured by the Security
Documents.  The Agent agrees to promptly notify the Company of any such tax,
assessment, standby fee, insurance premium or other sums paid by the Agent
pursuant to the immediately preceding sentence, but the failure to give such
notice shall not affect the obligation of the Loan Parties to repay any such
sums to the Agent.

                 (c)      All covenants and other obligations contained in the
Security Documents shall be in addition to the covenants contained herein.

Capital Stock (other than a Wholly Owned Restricted Subsidiary or employee
benefit plan or plan trust) (an "Affiliate Transaction") on terms that are less

employee benefit or compensation arrangements entered into in the ordinary
course of business and approved by the Board of Directors of the Company or the
Board of Directors of such Restricted Subsidiary permitted by this Agreement;

any Sale-Leaseback Transaction unless (a) the Company or such Restricted
Subsidiary, as the case may be, would be able to incur Indebtedness in an
amount equal to the Attributable Debt with respect to such Sale-Leaseback
Transaction and (b) the Company or such Restricted Subsidiary receives net
proceeds from such Sale-Leaseback Transaction at least equal to the fair market
value of the assets so sold (as determined by the Board of Directors of the
Company, whose determination in good faith evidenced by a Board Resolution
shall be conclusive).

               SECTION 8.13.    Change in Accounting.  The Company will not,
and will not permit any of the Restricted Subsidiaries to, change its method of

      any part of the Obligations, the Guaranteed Obligations, or any document
      or agreement executed in connection with the Obligations or the
      Guaranteed Obligations, for any reason whatsoever, including, without
      limitation, the fact that (A) the Obligations or the Guaranteed
      Obligations, or any part thereof, exceeds the amount permitted by law,
      (B) the act of creating the Obligations, the Guaranteed Obligations or
      any part thereof is ultra vires, (C) the officers or representatives
      executing the documents or otherwise creating the Obligations or the

      agreement or by statute) which render the Obligations or the Guaranteed
      Obligations wholly or partially uncollectible from the Company or such
      Subsidiary Guarantor, (F) the creation, performance or repayment of the

      uncollectible, legally impossible or unenforceable, or (G) this
      Agreement, any other Loan Document, or any other document or instrument
      pertaining to the Obligations or the Guaranteed Obligations has been

      and severally, to pay, perform, guarantee or assure the payment of the
      Obligations, the

<PAGE>   97
      Guaranteed Obligations or any part thereof; it being recognized,
      acknowledged and agreed by each Subsidiary Guarantor that such Subsidiary
      Guarantor may be required to pay the Obligations or the Guaranteed
      Obligations in full without assistance or support of any other Person,
      and such Subsidiary Guarantor has not been induced to enter into this
      Guaranty on the basis of a contemplation, belief, understanding or
      agreement that any other Person will be liable to perform the Obligations
      or the Guaranteed Obligations, or that the Agent or any Lender will look
      to any other Person to perform the Guaranteed Obligations;

               (vi)    the taking or accepting of any other security,
      collateral or guaranty, or other assurance of payment, for all or any
      part of the Obligations or the Guaranteed Obligations;

               (vii)   any release, surrender, exchange, subordination,
      deterioration, waste, loss or impairment of any collateral, property or
      security, at any time existing in connection with, or assuring or
      securing payment of, all or any part of the Obligations or the Guaranteed
      Obligations;

               (viii)  the failure of the Agent, the Lenders or any other
      Person to exercise diligence or reasonable care in the preservation,
      protection, enforcement, sale or other handling or treatment of all or
      any part of such collateral, property or security;

               (ix)    the fact that any collateral, security or Lien
      contemplated or intended to be given, created or granted as security for
      the repayment of the Obligations or the Guaranteed Obligations shall not
      be properly perfected or created, or shall prove to be unenforceable or
      subordinate to any other Lien; it being recognized and agreed by each
      Subsidiary Guarantor that such Subsidiary Guarantor is not entering into
      this Guaranty in reliance on, or in contemplation of the benefits of, the
      validity, enforceability, collectibility or value of any of the
      collateral for the Obligations or the Guaranteed Obligations;

               (x)     any payment by the Company or any Subsidiary Guarantor
      to the Agent or any Lender is held to constitute a preference under
      bankruptcy laws, or for any reason either the Agent or any Lender is
      required to refund such payment or pay such amount to the Company or any
      other Person; or

               (xi)    any other action taken or omitted to be taken with
      respect to this Agreement, any other Loan Document, the Obligations, the
      Guaranteed Obligations, or the security and collateral therefor, whether
      or not such action or omission prejudices any Subsidiary Guarantor or
      increases the likelihood that any Subsidiary Guarantor will be required
      to pay the Obligations or the Guaranteed Obligations pursuant to the
      terms hereof; it is the unambiguous and unequivocal intention of each
      Subsidiary Guarantor that such Subsidiary Guarantor shall be obligated to
      pay the Obligations or the Guaranteed Obligations when





                                       91
<PAGE>   98
      due, notwithstanding any occurrence, circumstance, event, action, or
      omission whatsoever, whether contemplated or uncontemplated, and whether
      or not otherwise or particularly described herein, except for the full
      and final payment and satisfaction of the Obligations or the Guaranteed
      Obligations after the termination of the Commitments of all Lenders and
      the expiration or termination of all Letters of Credit.

               (b)     Each Subsidiary Guarantor further agrees that, as
between such Subsidiary Guarantor, on the one hand, and the Lenders and the
Agent, on the other hand, (i) the maturity of the Guaranteed Obligations may be
accelerated as provided in Article X for the purposes of this Guaranty,
notwithstanding any stay, injunction or other prohibition preventing such
acceleration of the Obligations or the Guaranteed Obligations, and (ii) in the
event of any acceleration of the Obligations as provided in Article X, the
Guaranteed Obligations (whether or not due and payable) shall forthwith become
due and payable by each Subsidiary Guarantor for the purpose of this Guaranty.

               SECTION 9.03.    Effect of Debtor Relief Laws.  If after receipt
of any payment of, or proceeds of any security applied (or intended to be
applied) to the payment of all or any part of the Obligations or the Guaranteed
Obligations, the Agent or any Lender is for any reason compelled to surrender
or voluntarily surrenders, such payment or proceeds to any Person (a) because
such payment or application of proceeds is or may be avoided, invalidated,
declared fraudulent, set aside, determined to be void or voidable as a
preference, fraudulent conveyance, fraudulent transfer, impermissible set-off
or a diversion of trust funds or (b) for any other reason, including (i) any
judgment, decree or order of any court or administrative body having
jurisdiction over the Agent, any Lender or any of their respective properties
or (ii) any settlement or compromise of any such claim effected by the Agent or
any Lender with any such claimant (including the Company), then the
Obligations, the Guaranteed Obligations or part thereof intended to be
satisfied shall be reinstated and continue, and this Guaranty shall continue in
full force as if such payment or proceeds have not been received,
notwithstanding any revocation thereof or the cancellation of any Note or any
other instrument evidencing any of the Obligations or Guaranteed Obligations or
otherwise; and the Subsidiary Guarantors, jointly and severally, shall be
liable to pay the Agent and the Lenders, and hereby do indemnify the Agent and
the Lenders and hold them harmless for the amount of such payment or proceeds
so surrendered and all reasonable expenses (including reasonable attorneys'
fees, court costs and expenses attributable thereto) incurred by the Agent or
any Lender in the defense of any claim made against it that any payment or
proceeds received by the Agent or any Lender in respect of all or part of the
Obligations or the Guaranteed Obligations must be surrendered.  The provisions
of this paragraph shall survive the termination of this Guaranty, and any
satisfaction and discharge of the Company by virtue of any payment, court order
or any federal or state law.

               SECTION 9.04.    General Limitation on Guaranteed Obligations.
In any action or proceeding involving any state corporate law, or any state or
federal bankruptcy, insolvency, reorganization or other law affecting the
rights of creditors generally, if the obligations of any Subsidiary Guarantor
under Section 9.01 would otherwise, taking into account the provisions of
Section 9.05, be held or determined to be void, invalid or unenforceable, or
subordinated to the claims of any other creditors, on account of the amount of
its liability under Section 9.01, then, notwithstanding any other provision
hereof to the contrary, the amount of such liability shall, without any further
action by such Subsidiary Guarantor, any Lender, the Agent or any other Person,
be automatically limited and reduced to the highest amount that is valid and
enforceable and not subordinated to the claims of other creditors as determined
in such action or proceeding.

               SECTION 9.05.    Rights of Contribution. The Subsidiary
Guarantors hereby agree, as between themselves, that if any Subsidiary
Guarantor shall become an Excess Funding Obligor (as defined below) by reason
of the payment by such Subsidiary Guarantor of any Guaranteed Obligations, each
other Subsidiary Guarantor shall, on demand of such Excess Funding Obligor (but
subject to the next sentence), pay to such Excess Funding Obligor an amount
equal to such Subsidiary Guarantor's Pro Rata Share (as defined below and
determined, for this purpose, without reference to the properties, debts and
liabilities of such Excess Funding Obligor) of the Excess Payment (as defined
below) in respect of such Guaranteed Obligations.

               For purposes of this Section 9.05, (i) "Excess Funding Obligor"
shall mean, in respect of any Guaranteed Obligations, a Subsidiary Guarantor
that has paid an amount in excess of its Pro Rata Share of such Guaranteed
Obligations, (ii) "Excess Payment" shall mean, in respect of any Guaranteed
Obligations, the amount paid by an Excess Funding Obligor in excess of its Pro
Rata Share of such Guaranteed Obligations and (iii) "Pro Rata Share" shall
mean, for any Subsidiary Guarantor, the ratio (expressed as a percentage) of
(x) the amount by which the aggregate fair saleable value of all properties of
such Subsidiary Guarantor on the date of this Agreement exceeds the amount of
all the debts and liabilities of such Subsidiary Guarantor (including
contingent, subordinated, unmatured and unliquidated liabilities, but excluding
the obligations that have been guaranteed by such Subsidiary Guarantor in
Section 9.01) to (y) the amount by which the aggregate fair saleable value of
all assets of the Company and all the Subsidiary Guarantors exceeds the amount
of all the debts and liabilities (including contingent, subordinated, unmatured
and unliquidated liabilities, but excluding the obligations of the Company and
the Subsidiary Guarantors hereunder) of the Company and all the Subsidiary
Guarantors, all as of the Execution Date.

               SECTION 9.06.    Subrogation.  Notwithstanding any payment or
payments made by any Subsidiary Guarantor hereunder, or any set-off or
application by the Agent or any Lender of any security or of any credits or
claims, no Subsidiary Guarantor will assert or exercise any





                                       93
<PAGE>   100
rights of the Agent or any Lender or of such Subsidiary Guarantor against the
Company to recover the amount of any payment made by such Subsidiary Guarantor
to the Agent or any Lender hereunder by way of any claim, remedy or
subrogation, reimbursement, exoneration, contribution, indemnity, participation
or otherwise arising by contract, by statute, under common law or otherwise,
and such Subsidiary Guarantor shall not have any right of recourse to or any
claim against assets or property of the Company, until all of the Guaranteed
Obligations are paid in full after the termination of the Commitments of all
Lenders and the expiration or termination of all Letters of Credit.  If any
amount shall nevertheless be paid to a Subsidiary Guarantor by the Company or
another Subsidiary Guarantor prior to payment in full of the Obligations, such
amount shall be held in trust for the benefit of the Agent and the Lenders and
shall forthwith be paid to the Agent to be credited and applied to the
Guaranteed Obligations, whether matured or unmatured.  The provisions of this
paragraph shall survive the termination of this Guaranty, and any satisfaction
and discharge of the Company by virtue of any payment, court order or any
federal or state law.

               SECTION 9.07.    Subordination.  If any Subsidiary Guarantor
becomes the holder of any indebtedness payable by the Company or another
Subsidiary Guarantor (including any Permitted Business Investment made by any
such Subsidiary Guarantor to the Company), each Subsidiary Guarantor hereby
subordinates all indebtedness owing to it from the Company or such other
Subsidiary Guarantor to all indebtedness of the Company or such other
Subsidiary Guarantor to the Agent and the Lenders, and agrees that during the
continuance of any Default or Event of Default it shall not accept any payment
on the same until the first to occur of (a) the date such Default or Event of
Default no longer exists and (b) payment in full of the Obligations of the
Company under this Agreement and the other Loan Documents after the termination
of the Commitments of the Lenders and the termination or expiration of the
Letters of Credit, the Notes and all other Loan Documents, and, while any
Default or Event of Default exists, shall in no circumstance whatsoever attempt
to set-off or reduce any obligations hereunder because of such indebtedness.
If any amount shall nevertheless be paid to a Subsidiary Guarantor by the
Company or another Subsidiary Guarantor prior to payment in full of the
Guaranteed Obligations and, while any Default or Event of Default exists, such
amount shall be held in trust for the benefit of the Agent and the Lenders and
shall forthwith be paid to the Agent to be credited and applied to the
Guaranteed Obligations, whether matured or unmatured.

               SECTION 9.08.    Waiver.  Each Subsidiary Guarantor hereby
waives promptness, diligence, notice of acceptance and any other notice with
respect to any of the Guaranteed Obligations and this Guaranty and waives
presentment, demand for payment, notice of intent to accelerate, notice of
dishonor or nonpayment and any requirement that the Agent or any Lender
institute suit, collection proceedings or take any other action to collect the
Guaranteed Obligations, including any requirement that the Agent or any Lender
protect, secure, perfect or insure any Lien against any property subject
thereto or exhaust any right or take any





                                       94
<PAGE>   101
action against the Company or any other Person or any collateral (it being the
intention of the Agent, the Lenders and each Subsidiary Guarantor that this
Guaranty is to be a guaranty of payment and not of collection).  It shall not
be necessary for the Agent or any Lender, in order to enforce any payment by
any Subsidiary Guarantor hereunder, to institute suit or exhaust its rights and
remedies against the Company, any other Subsidiary Guarantor or any other
Person, including others liable to pay any Guaranteed Obligations, or to
enforce its rights against any security ever given to secure payment thereof.
Each Subsidiary Guarantor hereby expressly waives to the maximum extent
permitted by applicable law each and every right to which it may be entitled by
virtue of the suretyship laws of the State of New York or any other state in
which it may be located, including any and all rights it may have pursuant to
Rule 31, Texas Rules of Civil Procedure, Section 17.001 of the Texas Civil
Practice and Remedies Code and Chapter 34 of the Texas Business and Commerce
Code.  Each Subsidiary Guarantor hereby waives marshaling of assets and
liabilities, notice by the Agent or any Lender of any indebtedness or liability
to which such Lender applies or may apply any amounts received by such Lender,
and of the creation, advancement, increase, existence, extension, renewal,
rearrangement or modification of the Guaranteed Obligations.  Each Subsidiary
Guarantor expressly waives, to the extent permitted by applicable law, the
benefit of any and all laws providing for exemption of property from execution
or for valuation and appraisal upon foreclosure.

               SECTION 9.09.    Full Force and Effect.  This Guaranty  is a
continuing guaranty and shall remain in full force and effect until all of the
Guaranteed Obligations under this Agreement and the other Loan Documents and
all other amounts payable under this Guaranty have been paid in full (after the
termination of the Commitments of the Lenders and the termination or expiration
of the Letters of Credit).  All rights, remedies and powers provided in this
Guaranty may be exercised, and all waivers contained in this Guaranty may be
enforced, only to the extent that the exercise or enforcement thereof does not
violate any provisions of applicable law which may not be waived.

                         EVENTS OF DEFAULT AND REMEDIES

               SECTION 10.01.   Events of Default and Remedies.  If any of the
following events ("Events of Default") shall occur and be continuing:

               (a)     (i) any installment of principal on any Note or any
Unpaid Drawing shall not be paid on the date on which such payment is due or
(ii) any payment of interest on any such Note or Unpaid Drawing or any other
amount due hereunder or any other Loan Document shall not be paid within five
calendar days following the date on which such payment is due; or

Article V, deemed made by or on behalf of any Loan Party herein, at the
direction of any Loan Party or by any Loan Party in any other Loan Document or
in any document, certificate or financial statement delivered in connection

incorrect in any material respect when made or deemed made or reaffirmed, as
the case may be; or

               (c)     any Loan Party shall fail to perform or observe any

other Loan Document to which it is a party and, in any event, such failure
shall remain unremedied for 30 calendar days after the earlier of (i) written
notice of such failure shall have been given to a Responsible Officer of the
Company by the Agent or any Lender or, (ii) a Responsible Officer of any Loan
Party becomes aware of such failure; or

payment of or interest or premium, if any, on any Indebtedness (other than the
Notes or the Guaranty) beyond any period of grace provided with respect thereto
(not to exceed 30 days), provided that the aggregate amount of all Indebtedness
as to which such a payment default shall occur and be continuing is equal to or
exceeds $5,000,000, or (ii) fails to duly observe, perform or comply with any
agreement with any Person or any term or condition of any instrument, if such

an aggregate face amount which is equal to or exceeds $5,000,000; or

               (f)     the entry by a court having jurisdiction in the premises

(a "Notice of Default") take any or all of the following actions, without

Section 10.01(g)), it will pay to the Agent at the Agent's Payment Office such
additional amount of cash as is equal to the aggregate Stated Amount of all
Letters of Credit then outstanding to be held in an interest bearing account
with and under the sole dominion and control of the Agent as security for the
Obligations and the other obligations of the Loan Parties hereunder and under
the Notes and the other Loan Documents and the Loan Parties hereby grant the
Agent for the equal and ratable benefit of the Secured Parties a security
interest in such amount of cash.

               SECTION 10.02.   Other Remedies.  Upon the occurrence and during
the continuance of any Event of Default, the Agent, acting at the request of
the Majority Lenders, may proceed to protect and enforce its rights, either by
suit in equity or by action at law or both, whether for the specific
performance of any covenant or agreement contained in this Agreement or in any
other Loan Document or in aid of the exercise of any power granted in this
Agreement or in any other Loan Document; or may proceed to enforce the payment
of all amounts owing to the Agent and the Lenders under the Loan Documents and
interest thereon in the manner set forth herein or therein; it being intended
that no remedy conferred herein or in any of the other Loan Documents is to be
exclusive of any other remedy, and each and every remedy contained herein or in
any other Loan Document shall be cumulative and shall be in addition to every
other remedy given hereunder and under the other Loan Documents now or
hereafter existing at law or in equity or by statute or otherwise.

               SECTION 10.03.   Application of Moneys During Continuation of
Event of Default.  (a) So long as an Event of Default of which the Agent shall
have given notice to the Lenders shall continue, all moneys received by the
Agent (i) from any Loan Party under the Loan Documents, or (ii) as a result of
the enforcement of the rights and remedies of the Agent and the other Secured
Parties pursuant to the Loan Documents (including any sale of or realization
upon any Collateral) or otherwise, shall, except as otherwise provided in the
Security Documents or otherwise required by law, be distributed by the Agent on
the dates selected by the Agent (individually, a "Distribution Date" and
collectively, the "Distribution Dates") as follows:

      first, to payment of the reasonable expenses of any sale or other
      realization of the Collateral, including reasonable compensation to the
      Agent, agents of the Agent and counsel to the Agent, and all reasonable
      expenses, liabilities and advances incurred or made by the Agent in
      connection therewith, and any other unreimbursed expenses for which the
      Agent or any other Secured Party is to be reimbursed pursuant to Section
      12.04 or pursuant to the Security Documents and unpaid Fees owing to the
      Agent pursuant to Section 4.01(c);

      second, to the ratable payment of accrued but unpaid interest on the
      Obligations;

      third, to the ratable payment of unpaid principal of the Obligations;

      fourth, to the ratable payment of all other amounts payable by the Loan 
      Parties hereunder;

      fifth, to the ratable payment of all other Obligations, until all
      Obligations shall have been paid in full; and

      finally, to payment to the Loan Parties, or their respective successors
      or assigns, or as a court of competent jurisdiction may direct, of any
      surplus then remaining from such proceeds.

               (b)     The term "unpaid" as used in this Section 10.03 shall
mean all Obligations outstanding as of a Distribution Date (including any
amounts unpaid under clause (v) of the last sentence of Section 10.01) as to
which prior distributions have not been made, after giving effect to any
adjustments which are made pursuant to Section 12.06 of which the Agent shall
have been notified.

                                   ARTICLE XI

                                   THE  AGENT

               SECTION 11.01.   Authorization and Action.  Subject to Section
11.06, each Lender hereby irrevocably appoints and authorizes the Agent to act
on its behalf and to exercise such powers under this Agreement and the other
Loan Documents as are specifically delegated to or required of the Agent by the
terms hereof, together with such powers as are reasonably incidental thereto.
The Agent may perform any of its duties hereunder by or through its agents and
employees.  The duties of the Agent shall be mechanical and administrative in
nature; the Agent shall not have by reason of this Agreement or any other Loan
Documents a fiduciary relationship in respect of any Lender; and nothing in
this Agreement or any other Loan Document, expressed or implied, is intended
to, or shall be so construed as to, impose upon the Agent any obligations in
respect of this Agreement or any other Loan Document except as expressly set
forth herein or therein.  As to any matters not expressly provided for by this
Agreement, the Notes or the other Loan Documents (including enforcement of the
Liens created by the Security Documents and enforcement or collection of the
Notes), the 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 and all holders of Notes and the Obligations; provided, however, that
the Agent shall not be required to take any action which exposes the Agent to
personal liability or which is contrary to this Agreement or applicable law.

               SECTION 11.02.   Agent's Reliance, Etc.  (a) Neither the Agent
nor any of its directors, officers, agents or employees shall be liable to any
Lender for any action taken or omitted to be taken by it or them under or in
connection with this Agreement, the Notes or any of the other Loan Documents
(i) with the consent or at the request of the Majority Lenders or (ii) in the
absence of its or their own gross negligence or willful misconduct (IT BEING
THE EXPRESS INTENTION OF THE PARTIES HERETO THAT THE AGENT AND ITS DIRECTORS,
OFFICERS, AGENTS AND EMPLOYEES SHALL HAVE NO LIABILITY FOR ACTIONS AND
OMISSIONS UNDER THIS SECTION 11.02 RESULTING FROM THEIR SOLE OR CONCURRENT
NEGLIGENCE).

               (b)     Without limitation of the generality of the foregoing,
the Agent:  (i) may treat the payee of each Note and the Obligations as the
holder thereof until the Agent receives written notice of the assignment or
transfer thereof signed by such payee and in form satisfactory to the Agent;
(ii) may consult with legal counsel (including counsel for any Loan Party),
independent public accountants and other experts selected by it and shall not
be liable to the Lenders 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; (iii) makes no warranty or representation to any





                                      101
<PAGE>   108
Lender and shall not be responsible to any Lender for any statements,
warranties or representations made in or in connection with this Agreement, any
Note or any other Loan Document; (iv) except as otherwise expressly provided
herein, shall not have any duty to the Lenders to ascertain or to inquire as to
the performance or observance of any of the terms, covenants or conditions of
this Agreement, any Note or any other Loan Document or to inspect the property
(including the books and records) of any Loan Party; (v) except for the due
execution and delivery by the Agent of the Loan Documents to which it is a
party, shall not be responsible to any Lender for the due execution, legality,
validity, enforceability, collectibility, genuineness, sufficiency or value of
this Agreement, any Note, any other Loan Document or any other instrument or
document furnished pursuant hereto or thereto; (vi) shall not be responsible to
any Lender for the perfection or priority of any Lien securing the Obligations;
and (vii) shall incur no liability under or in respect of this Agreement, any
Note or any other Loan Document by acting upon any notice, consent, certificate
or other instrument or writing (which may be by telegram or telecopier)
reasonably believed by it to be genuine and signed or sent by the proper party
or parties.

               SECTION 11.03.   Agent and Affiliates; Chase and Affiliates.
Without limiting the right of any other Lender to engage in any business
transactions with any Loan Party or any of its Affiliates, with respect to
their commitments, the Loans made by them and the Notes issued to them, Chase
and each other Lender who may become the Agent shall have the same rights and
powers under this Agreement, its Notes and the other Loan Document as any other
Lender and may exercise the same as though it was not the Agent; and the term
"Lender" or "Lenders" shall, unless otherwise expressly indicated, include
Chase and any such other Lender, in their individual capacities.  Chase, each
other Person who becomes the Agent and their respective Affiliates may be
engaged in, or may hereafter engage in, one or more loan, letter of credit,
leasing or other financing activities not the subject of this Agreement
(collectively, the "Other Financings") with any Loan Party, any Restricted
Subsidiary or any of their respective Affiliates, or may act as trustee on
behalf of, or depositary for, or otherwise engage in other business
transactions with any Loan Party, any Restricted Subsidiary  or any of their
respective Affiliates (all Other Financings and other such business
transactions being collectively, the "Other Activities") with no responsibility
to account therefor to the Lenders.  Without limiting the rights and remedies
of the Lenders specifically set forth herein, no other Lender by virtue of
being a Lender hereunder shall have any interest in (a) any Other Activities,
(b) any present or future guaranty by or for the account of the Company not
contemplated or included herein, (c) any present or future offset exercised by
the Agent in respect of any such Other Activities, (d) any present or future
property taken as security for any such Other Activities or (e) any property
now or hereafter in the possession or control of the Agent which may be or
become security for the obligations of any Loan Party hereunder and under the
Notes and the other Loan Documents by reason of the general description of
indebtedness secured, or of property contained in any other agreements,
documents or instruments related to such Other Activities;





                                      102
<PAGE>   109
provided, however, that if any payment in respect of such guaranties or such
property or the proceeds thereof shall be applied to reduction of the
obligations evidenced hereunder and by the Notes, then each Lender shall be
entitled to share in such application according to its pro rata portion of such
obligations.

               SECTION 11.04.   Lender Credit Decision.  Each Lender
acknowledges and agrees that it has, independently and without reliance upon
the Agent or any other Lender and based on the financial statements referred to
in Section 6.07 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 and agrees that it will,
independently and without reliance upon the 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 and the other Loan Documents.

               SECTION 11.05.   Agent's Indemnity.  (a) The Agent shall not be
required to take any action hereunder or to prosecute or defend any suit in
respect of this Agreement, the Notes or any other Loan Document unless
indemnified to the Agent's satisfaction by the Lenders against loss, cost,
liability and expense.  If any indemnity furnished to the Agent shall become
impaired, it may call for additional indemnity and cease to do the acts
indemnified against until such additional indemnity is given.  In addition, the
Lenders agree to indemnify the Agent (to the extent not reimbursed by the
Company or any other Loan Party), ratably according to the respective aggregate
principal amounts of the Notes then held by each of them (or if no Notes are at
the time outstanding, ratably according to the respective amounts of their
Commitments, or if no Commitments are outstanding, the respective amounts of
the Commitments immediately prior to the time the Commitments ceased to be
outstanding), 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 the Agent in any way relating to or arising out of this
Agreement or any action taken or omitted by the Agent under this Agreement, the
Notes and the other Loan Documents (including any action taken or omitted under
Article II, Article III or Article IV of this Agreement).  Without limitation
of the foregoing, each Lender agrees to reimburse the Agent promptly upon
demand for its ratable share of any out-of-pocket expenses (including
reasonable counsel fees) incurred by the Agent in connection with the
preparation, execution, administration, or enforcement of, or legal advice in
respect of rights or responsibilities under, this Agreement, the Notes and the
other Loan Documents to the extent that the Agent is not reimbursed for such
expenses by a Loan Party.  The provisions of this Section 11.05 shall survive
the termination of this Agreement, the payment of the Obligations and/or the
assignment of any of the Notes.





                                      103
<PAGE>   110
               (b)     NOTWITHSTANDING THE FOREGOING, NO LENDER SHALL BE LIABLE
UNDER THIS SECTION 11.05 TO THE AGENT FOR ANY PORTION OF SUCH LIABILITIES,
OBLIGATIONS, LOSSES, DAMAGES, PENALTIES, ACTIONS, JUDGMENTS, SUITS, COSTS,
EXPENSES OR DISBURSEMENTS DUE TO THE AGENT RESULTING FROM THE AGENT'S GROSS
NEGLIGENCE OR WILLFUL MISCONDUCT.  EACH LENDER AGREES, HOWEVER, THAT IT
EXPRESSLY INTENDS, UNDER THIS SECTION 11.05, TO INDEMNIFY THE AGENT RATABLY AS
AFORESAID FOR ALL SUCH LIABILITIES, OBLIGATIONS, LOSSES, DAMAGES, PENALTIES,
ACTIONS, JUDGMENTS, SUITS, COSTS, EXPENSES AND DISBURSEMENTS ARISING OUT OF OR
RESULTING FROM THE AGENT'S ORDINARY SOLE OR CONCURRENT NEGLIGENCE.

               SECTION 11.06.   Successor Agent.  The Agent may resign at any
time by giving written notice thereof to the Lenders and the Company and may be
removed as Agent under this Agreement, the Notes and the other Loan Documents
at any time with or without cause by the Majority Lenders.  Upon any such
resignation or removal, the Majority Lenders shall have the right to appoint a
successor Agent.  If no successor Agent shall have been so appointed by the
Majority Lenders, and shall have accepted such appointment, within 30 calendar
days after the retiring Agent's giving of notice of resignation or the Majority
Lenders' removal of the retiring Agent, then the retiring Agent may, on behalf
of the Lenders, appoint a successor Agent, which shall be a commercial bank
organized or licensed under the laws of the United States of America or of any
state thereof and having a combined capital and surplus of at least
$100,000,000.  Upon the acceptance of any appointment as Agent hereunder and
under the Notes and the other Loan Documents 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,
the Notes and the other Loan Documents. After any retiring Agent's resignation
or removal as Agent hereunder and under the Notes and the other Loan Documents,
the provisions of this Article XI shall inure to its benefit as to any actions
taken or omitted to be taken by it while it was Agent under this Agreement, the
Notes and the other Loan Documents.

               SECTION 11.07.   Notice of Default.  The Agent shall not be
deemed to have knowledge or notice of the occurrence of any Default or Event of
Default hereunder unless the Agent shall have received notice from a Lender or
the Company referring to this Agreement, describing such Default or Event of
Default and stating that such notice is a "notice of default."  If the Agent
receives such notice, the Agent shall give notice thereof to the Lenders;
provided, however, if such notice is received from a Lender, the Agent also
shall give notice thereof to the Company.  The Agent shall be entitled to take
action or refrain from taking action with respect to such Default or Event of
Default as provided in Section 11.01 and Section 11.02.

               SECTION 11.08.   Consents under Security Documents.  The Agent
may, with the prior consent of the Majority Lenders (but not otherwise),
consent to any modification, supplement or waiver under any of the Security
Documents, provided that, without the prior





                                      104
<PAGE>   111
consent of all the Lenders, the Agent shall not release any Collateral or
otherwise terminate any Lien under any Security Document providing for
collateral security, or agree to additional obligations being secured by such
collateral security.

                                  ARTICLE XII

                                 MISCELLANEOUS

               SECTION 12.01.   Amendments, Etc.  No amendment or waiver of any
provision of this Agreement, any Note or any other Loan Document, nor consent
to any departure by any Loan Party herefrom or therefrom, shall in any event be
effective unless the same shall be in writing and signed by the Loan Parties
party thereto, as to amendments, and by the Majority Lenders in all cases, and
then, in any case, such waiver or consent shall be effective only in the
specific instance and for the specific purpose for which given; provided,
however, that no amendment, waiver, consent or release shall, unless in writing
and signed by 100% of the Lenders, do any of the following:  (a) change the
definition of "Majority Lenders," "Total Commitment" or "Percentage
Participation," (b) reduce or increase the amount or alter the terms of the
Commitment of any Lender or subject any Lender to any additional obligations,
(c) reduce the principal of, or rate or amount of interest applicable to, any
Loan or the reimbursement obligations of the Company under the Letters of
Credit other than as expressly provided in this Agreement, any Commitment Fees
or any Letter of Credit Fees, (d) postpone any date fixed for any payment of
principal of, or interest on, the Notes or the reimbursement obligations of the
Company under any Letter of Credit, (e) change this Section 12.01, (f) change
the aggregate unpaid principal amount of the Notes or the number of Lenders,
that shall be required for the Lenders or any of them to take any action
hereunder, (g) release any Subsidiary Guarantor, (h) effect any increase on the
advance rates under the Borrowing Base or (i) except as expressly provided in
Section 11.08, release any Collateral or other security for the Obligations
(except as expressly permitted pursuant to Section 8.02); and provided that no
amendment, waiver or consent shall, unless in writing and signed by the Agent
in addition to the Lenders required above to take such action, affect the
rights or duties of the Agent under this Agreement, any Note or any other Loan
Document.  Subject to the foregoing, the amendment or waiver of any provision
of Article VI, VII, VIII or IX may be effected with the consent of the Majority
Lenders.

               SECTION 12.02.   Notices, Etc.  The Agent, any Lender or the
holder of any of the Obligations, giving consent or notice or making any
request of any Loan Party provided for hereunder, shall notify each Lender and
the Agent thereof.  In the event that the holder of any Note or any of the
Obligations (including any Lender) shall transfer such Note or Obligations, it
shall promptly so advise the Agent which shall be entitled to assume
conclusively that no transfer of any Note or any of the Obligations has been
made by any holder (including





                                      105
<PAGE>   112
any Lender) unless and until the Agent receives written notice to the contrary.

               SECTION 12.03.   No Waiver; Remedies.  No failure on the part of
any Lender or the Agent to exercise, and no delay in exercising, any right
hereunder, under any Note or under any other Loan Document shall operate as a
waiver thereof; nor shall any single or partial exercise of any such right, or
any abandonment or discontinuance of any steps to enforce such right, preclude
any other or further exercise thereof or the exercise of any other right.  No
notice to or demand on any Loan Party in any case shall entitle such Loan Party
to any other or further notice or demand in similar or other circumstances.
The remedies herein provided are cumulative and not exclusive of any remedies
provided by law.

               SECTION 12.04.   Costs, Expenses and Taxes.  The Company agrees

release of Collateral pursuant to Section 8.02), the Notes and the other Loan
Documents, and any modification, supplement or waiver of any of the terms of
this Agreement or any other Loan Document, (b) all reasonable out-of-pocket
costs and expenses of the Agent in connection with the syndication of the
credit evidenced by this Agreement and the other Loan Documents, (c) all
recording, filing or other fees, costs and taxes incident to perfecting a Lien
upon the Collateral, and (d) all reasonable costs and expenses of each of the
Agent, the Lenders and any other holder of an interest in the Notes, and the
Obligations of the Loan Parties hereunder and under the Loan Documents,
including reasonable legal fees and expenses, in connection with a default or
the enforcement of this Agreement, the Notes or any other Loan Document.  In
addition, subject to Section 12.08, the Company shall pay any and all stamp and
similar taxes payable or determined to be payable in connection with the
execution and delivery of this Agreement, the Notes, the other Loan Documents
and the other documents to be delivered hereunder, and agrees to save the Agent
and each Lender harmless from and against any and all liabilities with respect
to or resulting from any delay in paying or omission to pay such taxes, if any,
which may be payable or determined to be payable in connection with the
execution and delivery of this Agreement, any Note or any other Loan Document.
Without prejudice to the survival of any other obligations of the Company
hereunder and under the Notes, the obligations of the Company under this
Section 12.04 shall survive the termination of this Agreement and the payment
of the Obligations or the assignment of the Notes.

               SECTION 12.05.   Indemnity.  (a) The Company shall indemnify the
Agent, the Lenders and each Affiliate thereof and their respective directors,
officers, employees and agents (each such Person being an "Indemnitee") from,
and hold each Indemnitee harmless against, any and all losses, liabilities,
claims or damages (including reasonable legal fees and expenses) to which any
Indemnitee may become subject, insofar as such losses, liabilities, claims or
damages





                                      108
<PAGE>   115
arise out of or result from (i) any actual or proposed use by the Company or
any Restricted Subsidiary of the proceeds of any extension of credit by any
Lender hereunder or (ii) any investigation, litigation or other proceeding
(including any threatened investigation or proceeding) relating to the
foregoing or any of the other Loan Documents, and the Company shall reimburse
each Indemnitee, upon demand for any expenses (including reasonable legal fees)
incurred in connection with any such investigation or proceeding; but excluding
any such losses, liabilities, claims, damages or expenses incurred by reason of
the gross negligence or willful misconduct of such Indemnitee.

               (b)     WITHOUT LIMITING ANY PROVISION OF THIS AGREEMENT, IT IS
THE EXPRESS INTENTION OF THE PARTIES HERETO THAT EACH INDEMNITEE HEREUNDER
SHALL BE INDEMNIFIED AND HELD HARMLESS AGAINST ANY AND ALL LOSSES, LIABILITIES,
CLAIMS OR DAMAGES ARISING OUT OF OR RESULTING FROM THE SOLE OR CONCURRENT
NEGLIGENCE OF SUCH INDEMNITEE.  Without prejudice to the survival of any other
obligations of the Company hereunder and under the other Loan Documents, the
obligations of the Company under this Section 12.05 shall survive the
termination of this Agreement and the other Loan Documents and the payment of
the Obligations or the assignment of the Notes.

               SECTION 12.06.   Right of Setoff.  If any Event of Default shall
have occurred and be continuing, each Lender is hereby authorized at any time
and from time to time, to the fullest extent permitted by law, to set off and
apply any and all deposits (general or special, time or demand, provisional or
final) at any time held and other indebtedness at any time owing by such
Lender, or any branch, subsidiary or Affiliate of such Lender, to or for the
credit or the account of any Loan Party against any and all the obligations of
such Loan Party to such Lender now or hereafter existing under this Agreement
and the other Loan Documents and other obligations of such Loan Party held by
such Lender, irrespective of whether or not such Lender or the Agent shall have
made any demand under this Agreement, such Note, the Obligations or such other
obligations and although the Obligations or such other obligations may be
unmatured.  Each Lender agrees to promptly notify the Company after any such
setoff and application made by such Lender, but the failure to give such notice
shall not affect the validity of such setoff and application.  The rights of
each Lender under this Section 12.06 are in addition to other rights and
remedies (including other rights of setoff) which such Lender may have.

               SECTION 12.07.   Governing Law.  Except as expressly provided in
Section 3.02(a), this Agreement, all Notes, the other Loan Documents and all
other documents executed in connection herewith and therewith and the rights
and obligations of the parties hereto and thereto, shall be deemed to be
contracts and agreements executed by the Loan Parties, the Agent and the
Lenders under the laws of the State of New York and of the United States of
America and for all purposes shall be construed in accordance with, and
governed by, the laws of said state and, to the extent controlling, of the
United States of America.

               SECTION 12.08.   Interest.  Each provision in this Agreement and
each other Loan Document is expressly limited so that in no event whatsoever
shall the amount paid, or otherwise agreed to be paid, to the Agent or any
Lender for the use, forbearance or detention of the money to be loaned under
this Agreement or any Loan Document or otherwise (including any sums paid as
required by any covenant or obligation contained herein or in any other Loan
Document which is for the use, forbearance or detention of such money), exceed
that amount of money which would cause the effective rate of interest to exceed
the Highest Lawful Rate.

               SECTION 12.09.   Survival of Representations and Warranties.
All representations, warranties and covenants contained herein or made in
writing by the Loan Parties in connection herewith and the other Loan Documents
shall survive the execution and delivery of this Agreement, the Notes and the
other Loan Documents until two years and one day after payment in full of the
Obligations and the termination of the Commitments of the Lenders and the
termination or expiration of the Letters of Credit, and will bind and inure to
the benefit of the respective successors and assigns of the parties hereto,
whether so expressed or not, provided, that the undertaking of the Lenders to
make Loans and extend credit to the Company and the undertaking of the Issuing
Bank to issue Letters of Credit for the account of the Company or the Company
and any of its Restricted Subsidiary shall not inure to the benefit of any
successor or assign of the Company, except as provided in Section 8.02.

               SECTION 12.10.   Binding Effect.  This Agreement shall become
effective when it shall have been executed by the Loan Parties and the Agent
and when the Agent shall have been notified by each Lender that such Lender has
executed it.

               SECTION 12.11.   Successors and Assigns; Participations.  (a)
All covenants, promises and agreements by or on behalf of the Loan Parties, the
Agent or the Lenders that are contained in this Agreement shall bind and inure
to the benefit of their respective successors and permitted assigns.  Except as
provided in Section 8.02, the Loan Parties may not assign or transfer any of
their rights or obligations hereunder without the written consent of all the
Lenders.

               (b)     Each Lender may, without the consent of any Loan Party,
sell participations to one or more banks in all or a portion of its rights and
obligations under this Agreement and the other Loan Documents (including all or
a portion of its Commitment, the Loans and the Obligations of the Loan Parties
owing to it and the Notes and participations in Letters of Credit held by it);
provided, however, that (i) the selling Lender's obligations under this
Agreement shall remain unchanged, (ii) such Lender shall remain solely
responsible to the other parties hereto for the performance of such
obligations, (iii) the participating banks or other entities shall be entitled
to the cost protection provisions contained in Article II, Article III and
Section 12.04; provided, however, the costs to which a participant shall be
entitled to obtain pursuant to





                                      110
<PAGE>   117
Articles II and III shall be determined by reference to such participant's
selling Lender and shall be recoverable solely from such selling Lender and
(iv) the Loan Parties, the Agent and the other Lenders shall continue to deal
solely and directly with the selling Lender in connection with such Lender's
rights and obligations under this Agreement and the other Loan Documents;
provided, however, as between the selling Lender and any such participant, the
selling Lender may grant such participant rights with respect to amendments,
modifications or waivers with respect to any Fees payable hereunder to such
Lender (including the amount and the dates fixed for the payment of any such
Fees) or the amount of principal or the rate of interest payable on, or the
dates fixed for any payment of principal of or interest on, the Loans, or the
release of any obligations of the Loan Parties hereunder and under the other
Loan Documents, or the release of any security for any of the Obligations.
Except with respect to the provision with respect to default and enforcement
contained in Section 12.04(d) provided to a participant pursuant to clause
(iii) of this Section 12.11(b), no participant shall be a third party
beneficiary of this Agreement and shall not be entitled to enforce any rights
provided to its selling Lender against the Company under this Agreement.

               (c)     A Lender may assign to any other Lender or Lenders or to
any Affiliate of a Lender and, with the consent of the Company and the Agent
(which consents shall not be unreasonably withheld), a Lender may assign to one
or more other Eligible Assignees all or a portion of its interests, rights, and
obligations under this Agreement and the other Loan Documents (including all or
a portion of its Commitment and the same portion of the Loans and other
Obligations of the Loan Parties at the time owing to it and the Note held by
it, including its participation in the Letters of Credit); provided, however,
that (i) each such assignment shall (A) be in a minimum principal amount of not
less than $10,000,000, (B) not reduce any Lender's Commitment to an amount less
than $10,000,000 (other than to zero) and (C) be of a constant, and not a
varying, percentage of all the assigning Lender's Commitment, rights and
obligations under this Agreement and (iv) the parties to each such assignment
shall execute and deliver to the Agent, for its acceptance and recording in the
Register (as defined below), an Assignment and Acceptance substantially in the
form of Exhibit 12.11 hereto (an "Assignment and Acceptance"), any Note subject
to such assignment and, in the case of the Eligible Assignee, an Administrative
Questionnaire.  In addition, the Agent shall receive a processing and recording
fee of $3,000 from the assigning Lender in connection with any such Assignment
and Acceptance; provided, however, that the Company shall pay to the Agent such
processing and recording fee in connection with any assignment pursuant to
Sections 2.11, 2.12, 2.13 and 3.05. Upon such execution, delivery, acceptance
and recording, from and after the effective date specified in each Assignment
and Acceptance, which effective date shall be at least five Business Days after
the execution thereof unless otherwise agreed to by the assigning Lender, the
Eligible Assignee thereunder and the Agent (x) the Eligible Assignee thereunder
shall be a party hereto and to the other Loan Documents and, to the extent
provided in such Assignment and Acceptance, have the rights and obligations of
a Lender hereunder and under the other Loan





                                      111
<PAGE>   118
Documents and (y) the assignor Lender thereunder shall, to the extent provided
in such Assignment and Acceptance, be released from its obligations under this
Agreement and the other Loan Documents (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 and the other Loan Documents, such
Lender shall cease to be a party hereto).

               (d)     By executing and delivering an Assignment and
Acceptance, the Lender assignor thereunder and the Eligible Assignee confirm to
and agree with each other and the other parties hereto as follows:  (i) other
than the representation and warranty that it is the legal and beneficial owner
of the interest being assigned thereby free and clear of any adverse claim
known to such Lender, such Lender assignor makes no representation or warranty
and assumes no responsibility with respect to any statements, warranties or
representations made in or in connection with this Agreement or the execution,
legality, validity, enforceability, genuineness, sufficiency or value of this
Agreement, the other Loan Documents or any other instrument or document
furnished pursuant hereto or thereto; (ii) such Lender assignor makes no
representation or warranty and assumes no responsibility with respect to the
financial condition of any Loan Party or the performance or observance of its
respective obligations under this Agreement or any other instrument or document
furnished pursuant hereto or thereto; (iii) such Eligible Assignee confirms
that it has received a copy of this Agreement together with copies of the most
recent financial statements delivered pursuant to Section 6.07 or Section 7.01
and such other documents and information as it has deemed appropriate to make
its own credit analysis and decision to enter into such Assignment and
Acceptance; (iv) such Eligible Assignee will, independently and without
reliance upon the Agent, such Lender assignor 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 and the other Loan Documents; (v) such Eligible Assignee
appoints and authorizes the Agent to take such action on behalf of such
Eligible Assignee and to exercise such powers under this Agreement and the
other Loan Documents as are delegated to the Agent by the terms hereof,
together with such powers as are reasonably incidental thereto; (vi) such
Eligible Assignee agrees that it will perform in accordance with its terms all
of the obligations which by the terms of this Agreement and the other Loan
Documents are required to be performed by it as a Lender; and (vii) such
Eligible Assignee confirms that it is an Eligible Assignee as defined herein.

               (e)     The Agent shall maintain at its office a copy of each
Assignment and Acceptance delivered to it and a register for the recordation of
the names and addresses of the Lenders and the Commitment of, and principal
amount of the Loans and other Obligations owing to, each Lender from time to
time (the "Register").  The entries in the Register shall be conclusive, in the
absence of manifest error, and the Loan Parties, the Agent and the Lenders may
treat each Person whose name is recorded in the Register as a Lender hereunder
for all purposes of this Agreement and the other Loan Documents.  The Register
shall be available for





                                      112
<PAGE>   119
inspection by the Loan Parties, any Lender or the Agent at any reasonable time
and from time to time upon reasonable prior notice.

               (f)     Upon its receipt of an Assignment and Acceptance
executed by an assigning Lender and an Eligible Assignee together with the Note
subject to such assignment and the written consent of the Company to such
assignment (to the extent required under Section 12.11(c)), the Agent shall, if
such Assignment and Acceptance has been completed and is substantially in the
form of Exhibit 12.11 hereto, (i) accept such Assignment and Acceptance, (ii)
record the information contained therein in the Register, and (iii) give prompt
notice thereof to the Lenders and the Company.  Within five Business Days after
receipt of such notice, the Company shall, at its own expense, execute and
deliver to the Agent in exchange for the surrendered Note, a new Note to the
order of such Eligible Assignee in an amount equal to the portion of the
Commitment of the assigning Lender assumed by it pursuant to such Assignment
and Acceptance and, if the assigning Lender has retained any of its Commitment
hereunder, a new Note to the order of the assigning Lender in an amount equal
to the portion of such Commitment retained by it hereunder.  Such new Notes
shall be in an aggregate principal amount equal to the aggregate principal
amount of such surrendered Note, shall be dated the effective date of such
Assignment and Acceptance and shall otherwise be in substantially the form of
Exhibit 12.11, as applicable, hereto.  Canceled Notes shall be returned to the
Company.

               (g)     Notwithstanding any other provision herein, any Lender
may, in connection with any assignment or participation or proposed assignment
or participation pursuant to this Section 12.11 disclose to the assignee or
participant or proposed assignee or participant, any information relating to
the Loan Parties furnished to such Lender by or on behalf of any Loan Party,
subject, however to the provisions of Section 12.12.

               (h)     Anything in this Section 12.11 to the contrary
notwithstanding, any Lender may at any time, without the consent of the Company
or the Agent, assign and pledge all or any portion of its Commitments and the
Loans owing to it to any Federal Reserve Bank (and its transferees) as
collateral security pursuant to Regulation A and any Operating Circular issued
by such Federal Reserve Bank.  No such assignment shall release the assigning
Lender from its obligations hereunder.

               (i)     All transfers of any interest in any Note hereunder
shall be in compliance with all federal and state securities laws, if
applicable.  Notwithstanding the foregoing sentence, however, the parties to
this Agreement do not intend that any transfer under this Section 12.11 be
construed as a "purchase" or "sale" of a "security" within the meaning of any
applicable federal or state securities laws.





                                      113
<PAGE>   120
               SECTION 12.12.   Confidentiality.  Each Lender agrees to
exercise its best efforts to keep any information delivered or made available
by any Loan Party to it (including any information obtained pursuant to Section
7.01) which is clearly indicated to be confidential information, confidential
from anyone other than Persons employed or retained by such Lender who are or
are expected to become engaged in evaluating, approving, structuring or
administering the Loans or the Letters of Credit; provided that nothing herein
shall prevent any Lender from disclosing such information (a) to any other
Lender, (b) pursuant to subpoena or upon the order of any court or
administrative agency, (c) upon the request or demand of any regulatory agency
or authority having jurisdiction over such Lender, (d) which has been publicly
disclosed, (e) to the extent reasonably required in connection with any
litigation to which either Agent, any Lender, any Loan Party or their
respective Affiliates may be a party, (f) to the extent reasonably required in
connection with the exercise of any remedy hereunder or under any other Loan
Document, (g) to such Lender's legal counsel and independent auditors and (h)
to any actual or proposed participant or assignee of all or part of its rights
hereunder which has agreed in writing to be bound by the provisions of this
Section 12.12.  Each Lender will promptly notify the Company of any information
that it is required or requested to deliver pursuant to clause (b) or (c) of
this Section 12.12 and, if no Loan Party is a party to any such litigation,
clause (e) of this Section 12.12.

               SECTION 12.13.   Pro Rata Treatment.  (a) Except as permitted
under Section 2.11 and Section 2.13, each payment or prepayment of principal,
if permitted under this Agreement, and each payment of interest with respect to
a Borrowing shall be made pro rata among the Lenders in accordance with the
respective principal amounts of the Loans extended by each Lender with respect
to such Borrowing.

               (b)     Each Lender agrees that if it shall, through the
exercise of a right of banker's lien, setoff or counterclaim against any Loan
Party (pursuant to Section 12.06 or otherwise), including a secured claim under
Section 506 of the Bankruptcy Code or other security or interest arising from,
or in lieu of, such secured claim, received by such Lender under any applicable
bankruptcy, insolvency or other similar law or otherwise, obtain payment
(voluntary or involuntary) in respect of the Notes, Loans, Unpaid Drawings and
other Obligations held by it (other than pursuant to Section 2.11, Section 2.13
and Section 3.05) as a result of which the unpaid principal portion of the
Notes and the Obligations held by it shall be proportionately less than the
unpaid principal portion of the Notes and Obligations held by any other Lender,
it shall be deemed to have simultaneously purchased from such other Lender a
participation in the Notes and Obligations held by such other Lender, so that
the aggregate unpaid principal amount of the Notes, Obligations and
participations in Notes held by each Lender shall be in the same proportion to
the aggregate unpaid principal amount of the Notes and Obligations then
outstanding as the principal amount of the Notes and other Obligations held by
it prior to such exercise of banker's lien, setoff or counterclaim was to the
principal amount





                                      114
<PAGE>   121
of all Notes and other Obligations outstanding prior to such exercise of
banker's lien, setoff or counterclaim; provided, however, that if any such
purchase or purchases or adjustments shall be made pursuant to this Section
12.13 and the payment giving rise thereto shall thereafter be recovered, such
purchase or purchases or adjustments shall be rescinded to the extent of such
recovery and the purchase price or prices or adjustments restored without
interest.  Each Loan Party expressly consents to the foregoing arrangements and
agrees that any Person holding a participation in the Notes and the Obligations
deemed to have been so purchased may exercise any and all rights of banker's
lien, setoff or counterclaim with respect to any and all moneys owing by such
Loan Party to such Person as fully as if such Person had made a Loan directly
to the Company in the amount of such participation.

               SECTION 12.14.   Independence of Covenants.  All covenants
contained in this Agreement and in the other Loan Documents shall be given
independent effect so that if a particular action or condition is not permitted
by any of such covenants, the fact that such action or condition would be
permitted by an exception to, or otherwise be within the limitations of,
another covenant, shall not avoid the occurrence of a Default or an Event of
Default if such action is taken or condition exists.

               SECTION 12.15.   Separability.  Should any clause, sentence,
paragraph or Section of this Agreement be judicially declared to be invalid,
unenforceable or void, such decision will not have the effect of invalidating
or voiding the remainder of this Agreement, and the parties hereto agree that
the part or parts of this Agreement so held to be invalid, unenforceable or
void will be deemed to have been stricken herefrom and the remainder will have
the same force and effectiveness as if such part or parts had never been
included herein.

               SECTION 12.16.   Execution in Counterparts.  This Agreement may
be executed in any number of counterparts and by different parties hereto in
separate counterparts, each of which when so executed shall be deemed to be an
original and all of which taken together shall constitute one and the same
agreement.

               SECTION 12.17.   Conflict with Security Documents.  In the case
of any conflict or inconsistency between any provision of this Agreement and
the provision of any Security Documents, the provision of this Agreement shall
control.

               SECTION 12.18.   Ratification of Security Documents.  Each Loan
Party hereby ratifies and confirms each of the Security Documents to which it
is a party (or,in the case of Grant Prideco, to which it, Prideco, Inc. or
Prideco Holdings, Inc. was a party) as security for the Secured Obligations (as
defined therein) of such Loan Party.

               SECTION 12.19.   SUBMISSION TO JURISDICTION.  (a) ANY LEGAL
ACTION OR PROCEEDING WITH RESPECT TO THIS AGREEMENT AND THE





                                      115

DESIGNEE, APPOINTEE AND AGENT IN NEW YORK, NEW YORK ON THE TERMS AND FOR THE
PURPOSES OF THIS PROVISION SATISFACTORY TO THE AGENT.  EACH LOAN PARTY FURTHER
IRREVOCABLY CONSENTS TO THE SERVICE OF PROCESS OUT OF ANY OF THE AFOREMENTIONED
COURTS IN ANY SUCH ACTION OR PROCEEDING BY THE MAILING OF COPIES THEREOF BY

NOTHING HEREIN SHALL AFFECT THE RIGHT OF THE AGENT OR ANY LENDER TO SERVE
PROCESS IN ANY OTHER MANNER PERMITTED BY LAW OR TO COMMENCE LEGAL PROCEEDINGS
OR OTHERWISE PROCEED AGAINST ANY LOAN PARTY IN ANY OTHER JURISDICTION.

               (b)     EACH OF THE LOAN PARTIES HEREBY IRREVOCABLY WAIVES ANY
OBJECTION WHICH IT MAY NOW OR HEREAFTER HAVE TO THE LAYING OF VENUE OF ANY OF
THE AFORESAID ACTIONS OR PROCEEDINGS ARISING OUT OF OR IN CONNECTION WITH THIS

[ENERGY VENTURES, INC. LETTERHEAD]


FOR IMMEDIATE RELEASE



December 5, 1996, Houston, Texas - Energy Ventures, Inc. (NYSE-EVI) today
announced that it has entered into an agreement to acquire GulfMark
International, Inc. pursuant to a tax free merger in which approximately 2.2
million shares of EVI Common Stock will be issued to the stockholders of
GulfMark.  Prior to the merger, GulfMark will spin-off to its stockholders the
stock of a newly formed company in which its marine transportation services
business will be contributed.  Following the spinoff, the remaining assets of
GulfMark will consist of approximately 2.2 million shares of EVI Common Stock,
GulfMark's erosion control business and certain corporate and miscellaneous
assets.  It is anticipated that GulfMark will have no material debt as of the
closing of the transaction.

The acquisition of GulfMark is expected to increase EVI's stockholder base
while allowing it to acquire a profitable low cost business with potential
synergies with EVI's businesses at an attractive price.  Revenues and operating
income for 1995 attributable to GulfMark's erosion control business was $8.8
million and $800,000, respectively.  The acquisition is subject to, among other
things, approval of the stockholders of EVI and GulfMark and certain customary
regulatory approvals.  It is currently anticipated that the acquisition will be
consummated in the first quarter of 1997.

operations in eight countries.  The Company manufactures drill pipe, premium
tubulars and production equipment.
