ITEM 4.          PURPOSE OF TRANSACTION

                 On May 21, 1997, the Company closed the transactions
contemplated by a certain Property Acquisition Agreement (the "PAA") entered
into as of April 29, 1997, a copy of which is filed as Exhibit A hereto and is
incorporated herein by reference, with The New Venus Exploration, Inc.
("Venus") and each of the Lomak Parties, pursuant to which the Company
purchased substantially all of the assets of Venus and certain properties from
the Lomak Parties in exchange for shares of the Company to be distributed to
the stockholders of Venus and to the Lomak Parties. As a result of the
transaction, Venus received 5,626,473 shares of the Common Stock, par value
$.01 per share (the "Common Stock") of Xplor and warrants to purchase an
additional 272,353 shares of Common Stock. Venus will hold such Common Stock
until it is distributed to its stockholders. The date of such distribution has
not yet been determined, but is expected to occur within a reasonable time
after the date thereof. This statement assumes such distribution by Venus has
been completed. As a result of such distribution, the Ames Parties will receive
approximately 3,725,919 of such shares of Common Stock and the balance will be
distributed to stockholders of Venus who are not members of the Ames Group and
not subject to the Shareholders' Agreement (as described below). The Lomak
Parties received 2,134,179 shares of Common Stock and warrants to purchase an
additional 192,353 shares of Common Stock. Pursuant to the terms of the PAA,
the Ames Parties and the Lomak Parties together with D H. Blair Investment
Banking Corp., a New York corporation ("Blair") and several entities affiliated
with Blair (together with Blair, the "Blair Parties") (collectively with the
Ames Parties and the Blair Parties, the "SA Parties") entered into a certain
Stockholders' Agreement dated May 21, 1997 (the "SA") a copy of which is filed
as Exhibit B hereto and incorporated herein by reference, pursuant





                                    -21-
<PAGE>   22
to which, among other things, the SA Parties agreed to the vote together on the
election of directors and agreed to certain restrictions upon the sale of
shares of Common Stock held by the SA Parties. The descriptions of PAA and the
SA contained herein do not purport to be complete and are qualified in their
entirety by reference to the terms of the PAA and the SA, and which are
attached hereto as Exhibit A and Exhibit B, respectively, and are incorporated
herein by reference.

                 Simultaneously with the closing of the PAA on May 21, 1997,
the Lomak Parties purchased 97,008 shares of Common Stock from Venturetek,
L.P., in exchange for $194,016 plus the transfer of 80,000 warrants to purchase
Xplor Common Stock to Venturetek, L.P.

                 The Ames Parties and the Lomak Parties will review on a
continuous basis their investment in the Common Stock and the Company's
business affairs and financial condition, as well as conditions in the
securities markets and general economic and industry conditions. The Ames
Parties and the Lomak Parties may in the future take such actions in respect of
their investment in the Common Stock as they deem appropriate in light of the
circumstances existing from time to time. Currently, these actions include
continuing to hold the shares they now beneficially own, exercising their
respective warrants or disposing of shares. Any sales or any other dispositions
by the Ames Parties or the Lomak Parties could be effected in private
transactions, through a public offering or, upon compliance with the rules
under the Securities Act of 1933, as amended (the "Securities Act"), in the
open market. Additionally, it is possible that the Ames Parties or the Lomak
Parties could seek to acquire additional shares, although they have no current
plans to do so.  Any acquisition of shares could be effected in the open
market, in privately negotiated transactions, or otherwise. Any sales,
purchases or transfers or other actions





                                    -22-
<PAGE>   23
described herein may be made at any time without further prior notice. In
reaching any conclusion as to the foregoing matters, the Ames Parties and the
Lomak Parties may take into consideration various factors, such as the
Company's business and prospects, other developments concerning the Company,
the obligations of, cash and financial resources of and other business
opportunities available to the Ames Parties and the Lomak Parties, general
economic conditions, the market price for shares of Common Stock and stock
market conditions.

                 In connection with the closing of the PAA, the paries thereto
agreed that the name of the Company should be changed. It is expected that the
name of the Company will be changed to Venus Exploration, Inc. within a
reasonable time after the date hereof.

                 Except as set forth in Item 6, Contracts, Arrangements,
Understandings or Relationships with Respect to Securities of the Issuer, or
otherwise set forth herein, the Ames Parties and the Lomak Parties have no
present plans or proposals which relate to or would result in any of the
actions described in subparagraphs (a) through (h) of Item 4 of Schedule 13D.

ITEM 5.          INTEREST IN SECURITIES OF THE ISSUER

purposes of Section 13(d) of the Securities Exchange Act of 1934, as amended.
Accordingly, each of the SA Parties may be deemed to beneficially own all of
the shares of Common Stock owned by all of the SA Parties. In addition, certain
members of the Ames Group are parties to the Ames Family Voting Trust Agreement
(the "AFVTA") pursuant to which such parties granted to Eugene L. Ames, Jr., as

expected to occur within a reasonable time after the date hereof.

                                   ARTICLE II
                    REPRESENTATIONS AND WARRANTIES OF XPLOR

              Except as set forth (by reference to the applicable Section of
this Agreement) in Xplor's disclosure schedule previously delivered to Venus
and the Lomak Entities (the "Xplor Disclosure Schedule"), a copy of which is
attached hereto as Schedule A, Xplor hereby agrees and represents and warrants
to Venus and the Lomak Entities as follows:

              Section 2.01.  Organization, Etc.  Xplor 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
conduct its business as it is now being conducted and to own, operate or lease
the properties and assets it currently owns, operates or holds under lease.
Xplor is duly qualified or licensed to do business and is in good standing as a
foreign corporation in each jurisdiction where the character of its business or
the nature of its properties or assets makes such qualification or licensing
necessary, except where the failure to so qualify or be licensed would not have
a Material Adverse Effect.  Schedule 2.01 to the Xplor Disclosure Schedule sets
forth a list of each jurisdiction in which Xplor is licensed or qualified to
transact business as a foreign entity.  Xplor has heretofore delivered to Venus
and the Lomak Entities true and correct copies of its Certificate of
Incorporation and Bylaws as in effect on the date hereof.  Schedule 2.01 to the
Xplor Disclosure Schedule sets forth a list of the officers and directors of
Xplor on the date hereof.

              Section 2.02. Capitalization.  The authorized capital stock of
Xplor consists of 15,000,000 shares of common stock, $.01 par value per share,
of which only 2,037,171 shares are issued and outstanding as of the date hereof
and 1,000,000 shares of Preferred Stock, $.01 par value per share, no shares of
which are issued and outstanding as of the date hereof.  558,502 shares of
Xplor Stock are held as treasury shares.  The designations, powers,
preferences, rights, qualifications, limitations and restrictions in respect of
each class and series of authorized capital stock of Xplor are as set forth in
Xplor's Certificate of Incorporation, and all such designations, powers,
preferences, rights, qualifications, limitations and restrictions are valid,
binding and enforceable and in accordance with all applicable laws.  All
outstanding shares of Xplor Stock have been duly authorized and validly issued
and are fully paid and non-assessable.  All of the outstanding shares of Xplor
Stock were issued in compliance with all applicable Federal and state
securities laws.  None of the





                                       3
<PAGE>   10
outstanding securities has been issued in violation of any pre-emptive rights,
rights of first refusal or similar rights.  Except as set forth in the Xplor
Disclosure Schedule, there are no outstanding options, warrants, convertible
securities, calls, rights, commitments, preemptive rights or agreements or
instruments or understandings or other securities of any character to which
Xplor is a party or by which Xplor is bound, obligating Xplor to issue, deliver
or sell, or cause to be issued, delivered or sold, contingently or otherwise,
additional shares of capital stock of Xplor or any securities or obligations
convertible into or exchangeable for such shares or to grant, extend or enter
into any such option, warrant, convertible security, call, right, commitment,
preemptive right or agreement.  There are no outstanding obligations,
contingent or otherwise, of Xplor to purchase, redeem or otherwise acquire any
capital stock of Xplor.  There are no voting trust agreements or other
contracts, agreements, arrangements, commitments, plans or understandings
restricting or otherwise relating to voting, dividend or other rights with
respect to Xplor's capital stock.  There are no bonds, debentures, notes or
other indebtedness having the right to vote (or convertible into securities
having the right to vote) on any matters on which Xplor stockholders may vote
issued or outstanding.  There is no liability for dividends declared or
accumulated but unpaid with respect to any of the shares of Xplor Stock. Upon
delivery of the certificates for the shares of Xplor Stock to be issued in the
Venus Exchange and in the Lomak Exchange in accordance with the terms of this
Agreement, such shares will be validly issued, fully paid and non-assessable.

              Section 2.03.  Authorization.  Xplor has all requisite corporate
power and corporate authority to enter into this Agreement and each of the
other agreements contemplated hereby, to carry out its obligations under this
Agreement and each of the other agreements contemplated hereby and to
consummate the transactions contemplated hereby and thereby.  The execution and
delivery by Xplor of this Agreement, the consummation of the transactions
contemplated hereby and the performance by Xplor of its obligations hereunder
have been duly authorized by all necessary corporate action.  This Agreement
has been duly executed and delivered by  Xplor and, assuming that this
Agreement constitutes the legal, valid and binding obligation of the other
parties hereto, constitutes the legal, valid and binding obligation of Xplor,
enforceable against it in accordance with its terms.

              Section 2.04.  No Violation.  The execution and delivery of this
Agreement by Xplor does not, and the consummation by Xplor of the transactions
contemplated hereby, and compliance with the terms hereof will not, (a)
conflict with, or result in any violation of or default (with or without notice
or lapse of time or both) or loss of any benefit under, any provision of its
Certificates of Incorporation or By-laws; (b) conflict with, or result in any
violation of or default (with or without notice or lapse of time or both) or
loss of any benefit under, any permit, concession, grant, assignment,
franchise, license, law, rule or regulation, or any judgment, decree or order
of any court or other governmental agency or instrumentality to which Xplor is
a party or to which any of its





                                       4
<PAGE>   11
respective properties or assets is subject; (c) conflict with, or result in a
breach or violation of or default (with or without notice or lapse of time or
both) or loss of any benefit under, or accelerate the performance required by,
the terms of any material agreement, contract, indenture or other instrument to
which Xplor is a party or to which any of its properties is subject, or
constitute a default or loss of any right thereunder or an event which, with
the lapse of time or notice or both, might result in a material default or loss
of any material right thereunder or the creation of any lien, charge or
encumbrance upon any of the properties or assets of Xplor; or (d) result in any
suspension, revocation, impairment, forfeiture or non-renewal of any material
Lease of Xplor.

              Section 2.05.  Approvals.  The execution and delivery of this
Agreement and each other agreement contemplated hereby, the performance by
Xplor of its obligations hereunder and thereunder and the consummation of the
transactions contemplated hereby and thereby by Xplor will not require the
consent, approval, order or authorization of any Governmental Entity or
Regulatory Authority or any other Person under any statute, law, rule,
regulation, permit, license, agreement, indenture or other instrument to which
Xplor is a party or to which any of its properties are subject, and no
declaration, filing or registration with any Governmental Entity or Regulatory
Authority is required or advisable by Xplor in connection with the execution
and delivery of this Agreement and each other agreement contemplated hereby,
the performance by Xplor of its obligations hereunder and thereunder the
consummation by Xplor of the transactions contemplated hereby and thereby other
than (i) compliance with any applicable requirements under the Exchange Act and
the Securities Act, (ii) foreign and state securities and "blue sky" laws, and
(iii) such other filings or registrations with, or authorizations, consents or
approvals of, governmental bodies, agencies, officials or authorities, the
failure of which to make or obtain would not have a Material Adverse Effect, or
would not materially adversely affect the ability of Xplor or to consummate the
Venus Exchange or Lomak Exchange.

              Section 2.06.  Xplor 10-K and Proxy Statement.

              (a) Xplor has delivered to Venus and the Lomak Entities its
Annual Report on Form 10-K for the fiscal year ended December 31, 1996 (the
"Xplor 10-K") and its most recent proxy statement which is dated May 18, 1996
(the "Proxy Statement").  Neither the Xplor 10-K nor the Proxy Statement
contain any untrue statement of a material fact or omit to state any material
fact necessary in order to make the statements made therein, in the light of
the circumstances under which they were made, not misleading, and the Xplor 10-
K (including the financial statements contained therein), and the Proxy
Statement as of its filing date, complied as to form in all material respects
with the applicable requirements of the Exchange Act and the applicable rules
and regulations thereunder.

<PAGE>   12
              (b) The financial statements of Xplor (including the related
notes) included in the Xplor 10-K fairly present the financial position of
Xplor and the results of operations and changes in financial condition as of
the dates and periods therein specified.  Such financial statements (including
the related notes) (i) have been prepared in accordance with generally accepted
accounting principles consistently applied throughout the periods involved
(except as otherwise noted therein) and with applicable accounting requirements
and published rules and regulations of the SEC with respect thereto and (ii)
reflect all liabilities of Xplor, whether or not accrued and whether contingent
or absolute, including, without limitation, those relating to taxes,
environmental compliance and hazardous materials, Leases, contracts and
"employee benefit plans" as such term is defined in Section 3(3) of ERISA and
all Encumbrances as are required to be reflected therein by such applicable
principles, requirements, rules and regulations.

              Section 2.07.  Absence of Certain Changes.  Since December 31,
1996, there has not been (i) any Material Adverse Change in the assets or
liabilities, or in the business or condition, financial or otherwise, or in the
results of operations or prospects, of Xplor (ii) any adverse change in the
assets or liabilities or in the business or condition, financial or otherwise,
of Xplor except in the ordinary course of business, (iii) any increase or
establishment of any reserve for taxes or any other liability on Xplor's books

practice; (iv) any change by Xplor in tax methods, principles or elections or
in accounting methods or principles that would be required to be disclosed
under generally accepted accounting principles; (v) any declaration, setting
aside or payment of any dividend or other distribution with respect to any

securities by Xplor or any repurchase, redemption or other acquisition by Xplor
of any outstanding shares of Xplor Stock or any other equity securities of, or
other ownership interests in, Xplor; (vii) any cancellation of debt by Xplor or
waiver of any claim or right of substantial value to Xplor; (viii) any
borrowing, agreement to borrow funds or guaranty by Xplor or any termination or
amendment of any evidence of indebtedness, contract, agreement, deed, mortgage,
lease, license or other instrument to which Xplor is bound or by which Xplor or
any of its properties or assets is bound other than in the ordinary course of
business and consistent with past practice; or (ix) except for the execution of
this Agreement, any material transaction by Xplor, including, but not limited
to, any sale, lease or other disposition of properties and assets of Xplor,
other than in the ordinary course of business and consistent with past
practices, and any merger or consolidation of Xplor with any other entity, and,
to the best knowledge of Xplor, no fact or condition exists or is contemplated
or threatened which could reasonably be anticipated to cause such a change in
the future.

              Section 2.08.  Litigation.  There is no action, suit,
arbitration, proceeding or, to the best knowledge of Xplor, investigation
pending or, to the best knowledge of

Xplor, threatened against or affecting or involving Xplor or any of its
properties, assets or rights or any of its officers, directors or employees in
their capacities as such, whether at law or equity ("Xplor Litigation"), and
Xplor has no knowledge of any facts that are likely to give rise to any Xplor
Litigation, that (in any case) is likely to have a Material Adverse Effect nor
is there any judgment, decree, injunction, rule or order of any Governmental
Entity or arbitrator outstanding against Xplor or any of its officers,
directors or employees in their capacities as such that is likely to have a
Material Adverse Effect or affect the ability of Xplor to consummate the
transactions contemplated by this Agreement.

              Section 2.09.  No Default.  Xplor is not in default or violation
(and no event has occurred which, with notice or the lapse of time or both,
would constitute a default or violation) of any term, condition or provision of
(i) its Certificate of Incorporation and Bylaws, (ii) any note, bond, mortgage,
indenture, license, agreement or other instrument or obligation to which it is
now a party or by which it or any of its properties or assets may be bound or
(iii) any order, writ, injunction, decree, statute, rule or regulation
applicable to it, except in the case of (ii) and (iii) for defaults or
violations which individually or in the aggregate would not have a Material
Adverse Effect.

              Section 2.10.  Compliance with Laws.  Xplor  is in compliance
with all applicable laws, rules or regulations relating to or affecting the
operation, conduct or ownership of its properties or business, other than
violations that individually or in the aggregate would not, and insofar as may
reasonably be foreseen in the future will not, have a Material Adverse Effect,
except as described in Schedule 2.10 to the Xplor Disclosure Schedule.  Neither
Xplor nor, to the best of Xplor's knowledge, any officer, consultant or
employee of Xplor  (in their capacity as such), is in default with respect to
any order, writ, injunction or decree known to or served upon Xplor  of any
Governmental Entity or Regulatory Authority, which default would have a
Material Adverse Effect.  To the best of Xplor's knowledge, there is no
existing law, rule, regulation or order, whether Federal, state or local, which
would prohibit or materially restrict Xplor from, or otherwise materially
adversely affect Xplor in, conducting its business in any jurisdiction in which
it is now conducting business.  Xplor holds all permits, licenses, variances,
exemptions, orders, franchises and approvals of all Governmental Entities
necessary for the lawful conduct of its business (the "Xplor Permits"), except
where the failure so to hold would not have a Material Adverse Effect.  Xplor
is in compliance with the terms of the Xplor Permits, except where the failure
so to comply would not have a Material Adverse Effect.

              Section 2.11.  Oil and Gas Reserves; Wells.

              (a) Xplor has provided to Venus and the Lomak Entities an
engineering report reviewed by Ryder Scott Company, independent petroleum
engineers, setting forth Xplor's oil and gas reserves and values as of December
31, 1996 (the "Xplor





                                       7
<PAGE>   14
Reserve Report"), a copy of which is attached hereto as Schedule AA.  The Xplor
Reserve Report sets forth a list of all Leases comprising Xplor's oil and gas
reserves and, to the best of Xplor's knowledge, accurately reflects Xplor's oil
and gas reserves as of its date and as of the date hereof, subject to normal
production.  Xplor is not aware of any change to its Leases since the date of
the Xplor Reserve Report that could have a Material Adverse Effect.  The
independent petroleum engineers were provided full access to Xplor's reserve
records and all other relevant information.

              (b)  Except as set forth in Schedule 2.11 to the Xplor Disclosure
Schedule, there is no well operated by Xplor, and to Xplor's knowledge, there
is no well operated by a third party on behalf of Xplor, that (i) is no longer
producing in commercial quantities and for which there are no definitive plans
to attempt to restore production in commercial quantities, (ii) is subject to
an exception to a requirement to plug and abandon issued by regulatory
authority having jurisdiction over the well, or (iii) has been plugged and
abandoned but has not been plugged and abandoned or reclaimed in accordance
with all applicable laws, and the proper plugging and abandonment or
reclamation of which would or could reasonably be expected to have a Material
Adverse Effect on Xplor.

              Section 2.12.  Title to Xplor Leases.  As to the interests in
each of the Leases listed in the Xplor Reserve Report, such interests include
100% of the interests in such Leases owned by Xplor as of the date hereof, and
upon Closing, Xplor will have that title to such interests which

              (i) entitles Xplor to receive not less than the interest shown in
Xplor Reserve Report as the "Net Revenue Interest" with respect to such Lease
in all hydrocarbons produced, saved and marketed from such Lease and in all
hydrocarbons produced, saved or marketed from any unit of which such Lease
forms a part and allocated to such Lease, all without reduction, suspension or
termination of such Net Revenue Interest throughout the duration of such Lease;

              (ii) obligates Xplor to bear a percentage of the costs and
expenses relating to the maintenance and development of, and operations
relating to, such Lease in an amount not greater than the "Working Interest"
set forth in the Xplor Reserve Report with respect to such Lease; and

              (iii) is free and clear of all liens, Encumbrances (except for
Permitted Encumbrances), gas imbalances, obligations or defects and is not
subject to any matters which will result in a breach of any representation or
warranty of Xplor herein affecting title.





                                       8

With respect to such Leases and any unit agreements, pooling agreements,
communitization agreements or other similar documents affecting or creating
interests therein,

              (s)    all such interests are valid and in full force and effect;

              (t)    neither Xplor, nor to the knowledge of Xplor, any other
party is in default under any contract, agreement or arrangement affecting such
Leases, except such defaults as would not have a Material Adverse Effect on
Xplor.

              (u)    except as set forth on Schedule 2.12 of the Xplor
Disclosure Schedule, there is no contract, agreement or arrangement (i)
requiring an expenditure now or in the future by the owner of the interest of
more than $50,000 or imposing an obligation or non contingent liability now or
in the future on the owner of the interests of more than $50,000, (ii)
involving the purchase or sale of hydrocarbons and which cannot be terminated
without penalty on thirty (30) days notice or less and/or (iii) governing the
operations among the working interest owners of the Leases which contains any
provision that is objectionable or unacceptable on the basis of generally
recognized industry standards applicable to the area where the affected Lease
is situated and which would have a material adverse effect on the ownership,
use, value or operation of the affected Lease;

              (v)    there are no express obligations to engage in continuous
development operations in order to maintain any such lease or other interest in
full force and effect except as described in the Xplor Reserve Report;

              (w)    there are no provisions applicable to such Leases or other
documents or interests which increase the royalty share of the lessor or the
overriding royalty interest of any other party or increase or decrease the
working interest of such interest without corresponding change in the Net
Revenue Interest;

              (x)    there are no royalty provisions which expressly prohibit 
the payment of royalty on the basis of proceeds received under a prudently
negotiated arms-length contract;

              (y)    except for Pugh Clause provisions and similar provisions
relating to development of all zones, upon establishment of production in
commercial quantities and until such production should cease, such Leases may
be maintained in full force and effect over the economic life of the property
involved in accordance with the respective habendum clauses contained in the
Leases beyond the respective primary terms set forth in such Leases; and





                                       9
<PAGE>   16
              (z)   there are no fixed lease terms which cannot be extended by
production at the end of the term.

              Section 2.13.  Other Real Property Owned or Leased.  Schedule AAA
hereto contains a list and brief description of all interests in real property
owned or leased by Xplor other than the Leases referred to in Section 2.12, as
well as all buildings and other structures and material improvements located on
such real property (including a brief description of the use to which such
property is being put or for which it was intended and in the case of any such
property which is leased, the name of the lessor, requirement of consent of the
lessor to assignment (including assignment by way of merger or change of
control), termination date or notice requirement with respect to termination,
annual rental and renewal or purchase options). With respect to such other real
property such interests represent all the interests in real property reasonably
required for the efficient operation of the Xplor Leases and, except as set
forth in Schedule AAA:

              (i)   Xplor is the owner or lessee, as the case may be, of all

used;

              (iv)  All improvements on such real property are generally in good

interferes with the economic value or use thereof. None of the buildings and
structures located on such real property nor any appurtenances thereto or
equipment thereon, nor the operation or maintenance thereof, violates in any
manner any restrictive covenants or encroaches on any property owned by others
nor does any building or structure of third parties encroach upon such
property. No condemnation proceeding is pending or threatened with respect to
any such property.

              Section 2.14.  Title to Other Assets, Properties and Rights and
Related Matters.  Schedule AAA hereto contains a list and brief description of

PARTICULAR PURPOSE OR (iv) ITS CONFORMITY TO MODELS OR SAMPLES OF MATERIALS

include all rights, properties, and interests in properties and assets (real,
personal and mixed, tangible and intangible, and all leases, licenses and other
agreements) necessary or desirable to permit Xplor to obtain the full economic
benefit of its business and of its ownership of the Xplor Leases as
contemplated hereby.

              Section 2.15.  No Misleading Statements.  This Agreement, the
information and Schedules and Exhibits referred to herein and the information

              Except as set forth (by reference to the applicable Section of
this Agreement) in Venus' disclosure schedule previously delivered to the Xplor

is duly qualified or licensed to do business and is in good standing as a

forth a list of each jurisdiction in which Venus is licensed or qualified to
transact business as a foreign entity.  Venus has heretofore delivered to Xplor

suspension, revocation, impairment, forfeiture or non-renewal of any material
Lease of Venus.

<PAGE>   22
not have a Material Adverse Effect, or would not materially adversely affect

              (a) Venus has delivered to Xplor and the Lomak Entities true,

at law or equity ("Venus Litigation"), and Venus has no knowledge of any facts
that are likely to give rise to any Venus Litigation, that (in any case) is
likely to have a Material Adverse Effect nor is there any judgment, decree,
injunction, rule or order of any Governmental Entity or arbitrator outstanding
against Venus or any of its officers, directors or employees in their
capacities as such that is likely to have a Material Adverse Effect or affect
the ability of Venus to consummate the transactions contemplated by this
Agreement.

              Section 3.09.  No Default.  Venus is not in default or violation
(and no event has occurred which, with notice or the lapse of time or both,
would constitute a default or violation) of any term, condition or provision of
(i) its Certificate of Incorporation and Bylaws, (ii) any note, bond, mortgage,
indenture, license, agreement or other instrument or obligation to which it is
now a party or by which it or any of its properties or assets may be bound or
(iii) any order, writ, injunction, decree, statute, rule or regulation
applicable to it, except in the case of (ii) and (iii) for defaults or
violations which individually or in the aggregate would not have a Material
Adverse Effect.

              Section 3.10.  Compliance with Laws.  Venus is in compliance with
all applicable laws, rules or regulations relating to or affecting the
operation, conduct or ownership of its properties or business, other than
violations that individually or in the aggregate would not, and insofar as may
reasonably be foreseen in the future will not, have a Material Adverse Effect,
all of which are described in Schedule 3.10 to the Venus Disclosure Schedule.
Neither Venus nor, to the best of Venus's knowledge, any officer, consultant or
employee of Venus (in their capacity as such), is in default with respect to
any order, writ, injunction or decree known to or served upon Venus of any
Governmental Entity or Regulatory Authority, which default would have a
Material Adverse Effect.  To the best of Venus's knowledge, there is no
existing law, rule, regulation or order, whether Federal, state or local, which
would prohibit or materially restrict Venus from, or otherwise materially
adversely affect Venus in, conducting its business in any jurisdiction in which
it is now conducting business.  Venus holds all





                                       17
<PAGE>   24
permits, licenses, variances, exemptions, orders, franchises and approvals of
all Governmental Entities necessary for the lawful conduct of their respective
businesses (the "Venus Permits"), except where the failure so to hold would not
have a Material Adverse Effect.  Venus is in compliance with the terms of the
Venus Permits, except where the failure so to comply would not have a Material
Adverse Effect.

              Section 3.11.  Oil and Gas Reserves; Wells.

              (a) Venus has provided to Xplor and the Lomak Entities
engineering reports reviewed by the following independent petroleum engineers:
Williamson Petroleum Consultants; Hite, Powers & Associates; and Cawley,
Gillespie, setting forth Venus's oil and gas reserves and values as of December
31, 1996, April 1, 1997 and March 31, 1997, respectively, copies of which are
attached hereto as Schedule BB (collectively, the "Venus Reserve Report").  The
Venus Reserve Report sets forth a list of all Leases comprising Venus's oil and
gas reserves and, to the best of Venus's knowledge, accurately reflects Venus's
oil and gas reserves as of its date and as of the date hereof, subject to
normal production.  Venus is not aware of any change to its Leases since the
date of the Venus Reserve Report that could have a Material Adverse Effect.
The independent petroleum engineers were provided full access to Venus's
reserve records and all other relevant information.

              (b) Except as set forth in Schedule 3.11 to the Venus Disclosure
Schedule, there is no well operated by Venus, and to Venus's knowledge, there
is no well operated by a third party on behalf of Venus, that (i) is no longer
producing in commercial quantities and for which there are no definitive plans
to attempt to restore production in commercial quantities, (ii) is subject to
an exception to a requirement to plug and abandon issued by regulatory
authority having jurisdiction over the well, or (iii) has been plugged and
abandoned but has not been plugged and abandoned or reclaimed in accordance
with all applicable laws, and the proper plugging and abandonment or
reclamation of which would or could reasonably be expected to have a Material
Adverse Effect on Venus.

              Section 3.12.  Title to Venus Leases.  As to the interests in
each of the Leases listed in the Venus Reserve Report, such interests include
100% of the interests in such Leases owned by Venus as of the date hereof, and
upon Closing, Venus will convey to Xplor that title to such interests that
will:

              (i) entitle Xplor to receive not less than the interest shown in
Venus Reserve Report as the "Net Revenue Interest" with respect to such Lease
in all hydrocarbons produced, saved and marketed from such Lease and or all
hydrocarbons produced, saved or marketed from any unit of which such Lease
forms a part and allocated to such Lease, all without reduction, suspension or
termination of such Net Revenue Interest throughout the duration of such Lease;





                                       18
<PAGE>   25
              (ii) obligate Xplor to bear a percentage of the costs and
expenses relating to the maintenance and development of, and operations
relating to, such Lease in an amount not greater than the "Working Interest"
set forth in the Venus Reserve Report with respect to such Lease; and

              (iii) is free and clear of all liens, Encumbrances (except for
Permitted Encumbrances), gas imbalances, obligations or defects and is not
subject to any matters which will result in a breach of any representation or
warranty of Venus herein affecting title.

With respect to such Leases and any unit agreements, pooling agreements,
communitization agreements or other similar documents affecting or creating
interests therein:

              (v) all such interests are valid and in full force and effect;

              (w) neither Venus, nor to the knowledge of Venus, any other party
is in default under any contract, agreement or arrangement affecting such
Leases, except such defaults as would not have a Material Adverse Effect on
Venus.

              (x) except as set forth on Schedule 3.12 of the Venus Disclosure
Schedule, there is no contract, agreement or arrangement (i) requiring an
expenditure now or in the future by the owner of the interest of more than
$50,000 or imposing an obligation or non contingent liability now or in the
future on the owner of the Interests of more than $50,000, (ii) involving the
purchase or sale of hydrocarbons and which cannot be terminated without penalty
on thirty (30) days notice or less and/or (iii) governing the operations among
the working interest owners of the Leases which contains any provision that is
objectionable or unacceptable on the basis of generally recognized industry
standards applicable to the area where the affected Lease is situated and which
would have a material adverse effect on the ownership, use, value or operation
of the affected Lease;

              (y) except for Pugh Clause provisions and similar provisions
relating to development of all zones, upon establishment of production in
commercial quantities and until such production should cease, such Leases may
be maintained in full force and effect over the economic life of the property
involved in accordance with the respective habendum clauses contained in the
Leases beyond the respective primary terms set forth in such Leases; and

              (z) there are no fixed lease terms which cannot be extended by
production at the end of the term.

hereto contains a list and brief description of all interests in real property
owned or leased by Venus other than the Leases referred to in Section 3.12, as
well as all buildings and other structures and material improvements located on
such real property (including a brief description of the use to which such
property is being put or for which it was intended and in the case of any such
property which is leased, the name of the lessor, requirement of consent of the
lessor to assignment (including assignment by way of merger or change of
control), termination date or notice requirement with respect to termination,

required for the efficient operation of the Venus Leases and, except as set
forth in Schedule BBB:

              (i) Venus is the owner or lessee, as the case may be, of all such
real property, free and clear of all Encumbrances (except Permitted
Encumbrances);

              (ii) Venus has made available to Xplor and the Lomak Entities
true and correct copies of all leases referred to in Schedule BBB hereto;

              (iii) All improvements on such real property conform in all
material respects to applicable Federal, state, local and foreign laws and
regulations (including applicable environmental and occupational safety and
health laws and regulations) and zoning and building ordinances, and such real
property is zoned for the various purposes for which it is presently being
used;

              (iv) All improvements on such real property are generally in good
operating condition and repair and there does not exist any condition which
interferes with the economic value or use thereof. None of the buildings and
structures located on such real property nor any appurtenances thereto or
equipment thereon, nor the operation or maintenance thereof, violates in any
manner any restrictive covenants or encroaches on any property owned by others
nor does any building or structure of third parties encroach upon such
property. No condemnation proceeding is pending or threatened with respect to
any such property.

              Section 3.14.  Title to Other Assets, Properties and Rights and
Related Matters. Schedule BBB hereto contains a list and brief description of

assets, properties and rights, including all such assets, properties and rights
reflected in the Venus Financial Statements as well as such of like kind and
character acquired after the date thereof (except inventory or other property
sold or otherwise disposed of since that date in the ordinary course of
business) free and clear of all Encumbrances of any kind or character, except
(i) those





                                       20
<PAGE>   27
set forth in Schedule BBB hereto and (ii) Permitted Encumbrances.  Such assets,
properties and rights are generally in good operating condition and repair
(ordinary wear and tear excepted), and there does not exist any condition which
interferes with the economic value or use thereof.  Except as provided in this
Section 3.14, VENUS MAKES NO AND DISCLAIMS ANY REPRESENTATION OR WARRANTY,
WHETHER EXPRESS OR IMPLIED, AND WHETHER BY COMMON LAW, STATUTE OR OTHERWISE, AS
TO (i) THE QUALITY, CONDITION OR OPERABILITY OF ANY PERSONAL PROPERTY OR
EQUIPMENT, (ii) ITS MERCHANTABILITY, (iii) ITS FITNESS FOR ANY PARTICULAR
PURPOSE OR (iv) ITS CONFORMITY TO MODELS OR SAMPLES OF MATERIALS AND, EXCEPT AS
PROVIDED IN THIS SECTION, ALL PERSONAL PROPERTY AND EQUIPMENT IS DELIVERED "AS

in Schedule BBB hereto, such assets, properties and rights shall include all
rights, properties, and interests in properties and assets (real, personal and
mixed, tangible and intangible, and all leases, licenses and other agreements)
necessary or desirable to permit Venus to obtain the full economic benefit of
its business and of its ownership of the Venus Leases as contemplated hereby.

              Section 3.15.  No Misleading Statements.  This Agreement, the
information and Schedules and Exhibits referred to herein and the information
that has been furnished to Xplor and the Lomak Entities by Venus in connection
with the transactions contemplated hereby do not include any untrue statement
of a material fact and do not omit to state any material fact necessary to make
the statements contained herein or therein, in light of the circumstances under
which they were made, not misleading.  Notwithstanding the foregoing, Venus has
not and does not make any representation or warranty regarding any forecast or
projection of future events, pricing, valuation or results of future operations
or, or related to, Venus' properties.  Nothing in this Agreement shall be
considered as an assurance that any such forecast or projection will be correct
or is likely to be correct.

              Section 3.16.  Brokerage Fees.  Venus has not retained any
financial advisor, broker, agent or finder or paid or agreed to pay any
financial advisor, broker, agent or finder on account of this Agreement or any

<PAGE>   28
Venus is or was a member has (i) timely (taking into account any extensions)
filed all federal and all material state, local and foreign returns,
declarations, reports, estimates, information returns and statements
("Returns") required to be filed or sent by or with respect to it in respect of
any Taxes, (B) timely paid all Taxes that are due and payable (except for audit

therefor is reserved for in the Venus's most recent audited financial
statements) for which Venus may be liable, (C) established reserves that are

the last taxable period through which the federal income Tax Returns of Venus
have been examined by the Internal Revenue Service ("IRS") or otherwise closed.
Except to the extent being contested in good faith, all material deficiencies
asserted as a result of such examinations and any examination by any applicable
state or local taxing authority have been paid, fully settled or adequately
provided for in Venus's most recent audited financial statements.  No material
federal, state or local income or franchise tax audits or other administrative
proceedings or court proceedings are presently pending with regard to any
federal, state or local income or franchise Taxes for which Venus would be
liable, and no material deficiency for any such income or franchise Taxes has
been proposed, asserted or assessed pursuant to such examination against Venus
by any federal, state or local taxing authority with respect to any period
other than as set forth in Schedule 3.18(a) to the Venus Disclosure Schedule.

              (c) Venus has not executed or entered into (and prior to the
close of business on the Closing Date will not execute or enter into) with the
IRS or any taxing authority (i) any agreement or other document extending or
having the effect of extending the period for assessments or collection of any

liable or (ii) a closing agreement pursuant to Section 7121 of the Code, or any
predecessor provision thereof or any similar provision of state or local income
tax law that relates to the assets or operations of Venus.

              (d) Venus is not a party to an agreement that provides for the
payment of any amount that would constitute a "parachute payment" within the
meaning of Section 280G of the Code.

              (e) Venus is not a party to or bound by any tax sharing agreement
or similar agreement or arrangement.

failure to so qualify or be licensed would not have a Material Adverse Effect.
Each of Production and Resources has heretofore delivered to Xplor and Venus
true and correct copies of its respective limited partnership agreement and
articles of organization and operating agreement in effect on the date hereof
("Lomak Governing Documents").  Schedule 4.01 to the Lomak Disclosure Schedule

<PAGE>   31

material Lease of Production or Resources constituting part of the Lomak
Properties.

              Section 4.04.  Approvals.  The execution and delivery of this
Agreement and each other agreement contemplated hereby, the performance by each

any other Person under any statute, law, rule, regulation, permit, license,
agreement, indenture or other instrument to which Production or Resources is a
party or to which any of its properties are subject, and no declaration, filing

materially adversely affect the Lomak Properties.

              Section 4.05.  Lomak Financial Statements.

              (a) The Lomak Entities have delivered to Xplor and Venus true,
correct and complete copies of a statement of assets and liabilities of the
Lomak Properties as of December 31, 1996 and the related statements of revenues
and direct operating expenses for the fiscal year then ended together with

Statements").

              (b) The Lomak Financial Statements fairly present the financial
position of the Lomak Properties and the results of operations and changes in

review and adjustment, (i) have been prepared in accordance with generally
accepted accounting principles consistently applied throughout the periods
involved (except as otherwise noted therein) and with applicable accounting
requirements and published rules and regulations of the SEC and (ii) reflect
all liabilities of the Lomak Properties, whether or not accrued and whether
contingent or absolute, including, without limitation, those relating to
severance and production taxes as are required to be reflected therein by such
applicable principles, requirements, rules and regulations.





                                       25
<PAGE>   32
              Section 4.06.  Absence of Certain Changes.  Since December 31,
1996, there has not been any Material Adverse Change in the condition,
financial or otherwise, or in the results of operations or prospects, of the
Lomak Properties.

              Section 4.07.  Litigation.  There is no action, suit,
arbitration, proceeding or, to the best knowledge of the Lomak Entities,
investigation pending or, to the best knowledge of the Lomak Entities,
threatened against or affecting or involving Production or Resources or any of
their respective properties, assets or rights or any of their officers,
directors or employees in their capacities as such, whether at law or equity
("Lomak  Litigation"), and the Lomak Entities have no knowledge of any facts
that are likely to give rise to any Lomak Litigation, that (in any case) is
likely to have a Material Adverse Effect nor is there any judgment, decree,
injunction, rule or order of any Governmental Entity or arbitrator outstanding
against Production or Resources or any of their partners, managers or employees
in their capacities as such that is likely to have a Material Adverse Effect or
affect the ability of Production or Resources to consummate the transactions
contemplated by this Agreement.

              Section 4.08.  No Default.  The Lomak Entities are not in default
or violation (and no event has occurred which, with notice or the lapse of time
or both, would constitute a default or violation) of any term, condition or
provision of (i) the Lomak Governing Documents (ii) any note, bond, mortgage,
indenture, license, agreement or other instrument or obligation to which either
is now a party or by which either it or any of its properties or assets may be
bound or (iii) any order, writ, injunction, decree, statute, rule or regulation
applicable to it, except in the case of (ii) and (iii) for defaults or
violations which individually or in the aggregate would not have a Material
Adverse Effect.

              Section 4.09.  Compliance with Laws.  Each of Production and
Resources is in compliance with all applicable laws, rules or regulations
relating to or affecting the operation, conduct or ownership of their
respective properties or business, other than violations that individually or
in the aggregate would not, and insofar as may reasonably be foreseen in the
future will not, have a Material Adverse Effect, all of which are described in
Schedule 4.09 to the Lomak Disclosure Schedule.  Neither the Lomak Entities
nor, to the best of the Lomak Entities' knowledge, any partner, manager,
consultant or employee of Production or Resources (in their capacity as such),
is in default with respect to any order, writ, injunction or decree known to or
served upon Production or Resources of any Governmental Entity or Regulatory
Authority, which default would have a Material Adverse Effect.  To the best of
the Lomak Entities' knowledge, there is no existing law, rule, regulation or
order, whether Federal, state or local, which would prohibit or materially
restrict Production or Resources from, or otherwise materially adversely affect
Production or Resources in, conducting its business in any jurisdiction in
which it is now conducting business.  Production and Resources hold all
permits, licenses, variances, exemptions, orders, franchises and





                                       26
<PAGE>   33
approvals of all Governmental Entities necessary for the lawful conduct of
their respective businesses (the "Lomak Entities Permits"), except where the
failure so to hold would not have a Material Adverse Effect.  Production and
Resources are in compliance with the terms of the Lomak Entities Permits,
except where the failure so to comply would not have a Material Adverse Effect.

              Section 4.10.  Oil and Gas Reserves; Wells.  The Lomak Entities
have provided to Xplor and Venus an engineering report reviewed by Wright &
Company, Inc. setting forth oil and gas reserves comprising the Lomak
Properties and their values as of December 31, 1996 (the "Lomak Reserve
Report"), a copy of which is attached hereto as Schedule CC.  The Lomak Reserve
Report sets forth a list of all Leases comprising the oil and gas reserves of
the Lomak Properties and, to the best of the Lomak Entities' knowledge,
accurately reflects such oil and gas reserves as of its date and as of the date
hereof, subject to normal production.  The Lomak Entities are not aware of any
change to their Leases since the date of the Lomak Reserve Report that could
have a Material Adverse Effect.  Wright & Company, Inc. were provided full
access to the Lomak Entities' reserve records and all other relevant
information.

              Section 4.11.  Title to Lomak Leases.  As to the interests in
each of the Leases listed in the Lomak Reserve Report, such interests include
100% of the interests in such Leases owned by the Lomak Entities as of the date
hereof, and upon Closing, the Lomak Entities will convey to Xplor that title to
such interests which will:

              (i) entitle Xplor to receive not less than the interest shown in
the Lomak Reserve Report as the "Net Revenue Interest" with respect to such
Lease in all hydrocarbons produced, saved and marketed from such Lease and in

accounting firm mutually acceptable to Xplor and the Lomak Entities.  The Lomak
Entities and Xplor agree to be bound by the findings of such audit insofar as
the settlement statement is concerned.  The fees and expenses involved in such
audit shall be paid by the party against which an adjustment is made.

         THIS WARRANT HAS NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933,
         OR THE SECURITIES LAWS OF ANY STATE, PURSUANT TO ONE OR MORE
         EXEMPTIONS THEREFROM.  THIS WARRANT MAY NOT BE SOLD, TRANSFERRED,
         ASSIGNED OR OTHERWISE DISPOSED OF WITHOUT REGISTRATION UNDER SUCH LAWS
         OR PURSUANT TO EXEMPTIONS THEREUNDER.


            Void after 5:00 p.m. New York Time, on October 23, 2000
               Warrant to Purchase ______ Shares of Common Stock.



                        WARRANT TO PURCHASE COMMON STOCK
                                       OF
                               XPLOR CORPORATION

                 This is to Certify That, FOR VALUE RECEIVED, ______________.,
or assigns ("Holder"), is entitled to purchase, subject to the provisions of
this Warrant, from Xplor Corporation, a Delaware corporation ("Company"),
_______ fully paid, validly issued and nonassessable shares of Common Stock,
par value $0.01 per share, of the Company ("Common Stock") at a price of $3.00
per share at any time or from time to time during the period from the date
hereof to October 23, 2000 but not later than 5:00 p.m. New York City Time, on
October 23, 2000.  The number of shares of Common Stock to be received upon the
exercise of this Warrant and the price to be paid for each share of Common
Stock may be adjusted from time to time as hereinafter set forth.  The shares
of Common Stock deliverable upon such exercise, and as adjusted from time to
time, are hereinafter sometimes referred to as "Warrant Shares" and the
exercise price of a share of Common Stock in effect at any time and as adjusted
from time to time is hereinafter sometimes referred to as the "Exercise Price".

                 (a)      EXERCISE OF WARRANT.  This Warrant may be exercised
in whole or in part at any time or from time to time on or after the date
hereof and until October 23, 2000 (the "Exercise Period"); provided, however,
that if either such day is a day on which banking institutions in the State of
New York are authorized by law to close, then this Warrant may be exercised, in
whole or in part, on the next succeeding day which shall not be such a day.
This Warrant may be exercised by presentation and surrender hereof to the
Company at its principal office, or at the office of its stock transfer agent,
if any, with the Purchase Form annexed hereto duly executed and accompanied by
payment of the Exercise Price for the number of Warrant Shares specified in
such form.  As soon as practicable after each such exercise of this Warrant,
but not later than seven (7) days from the date of such exercise, the Company
shall issue and deliver to the Holder a certificate or certificates for the
Warrant Shares



<PAGE>   67
issuable upon such exercise, registered in the name of the Holder or its
designee.  If this Warrant should be exercised in part only, the Company shall,
upon surrender of this Warrant for cancellation, execute and deliver a new
Warrant evidencing the rights of the Holder thereof to purchase the balance of
the Warrant Shares purchasable thereunder.  Upon receipt by the Company of this
Warrant at its office, or by the stock transfer agent of the Company at its
office, in proper form for exercise, the Holder shall be deemed to be the
holder of record of the shares of Common Stock issuable upon such exercise,
notwithstanding that the stock transfer books of the Company shall then be
closed or that certificates representing such shares of Common Stock shall not
then be physically delivered to the Holder.

                 (b)      TRANSFER RESTRICTION LEGEND.  Each certificate
representing Warrant Shares initially issued upon exercise of this Warrant,
unless at the time of exercise such Warrant Shares are registered under the
Securities Act, shall bear the following legend (and any additional legend
required by any securities exchange on which the Warrant Shares may at the time
be listed) on the face thereof:

         "The securities represented hereby have not been registered under the
         Securities Act of 1933, and the transfer of such securities is subject
         to the restrictions set forth in the Warrant pursuant to which such
         securities have been issued, a copy of which is available for
         inspection at the principal executive offices of Xplor Corporation,
         and no transfer of such securities shall be valid or effective unless
         and until the terms and conditions of said Warrant shall have been
         complied with."

Any certificate issued at any time upon transfer of, or in exchange for or
replacement of, any certificate bearing such legend (except a new certificate
issued upon completion of a public distribution of the securities represented
thereby pursuant to a registration under the Securities Act) shall also bear
such legend unless, in the opinion of counsel for the Company, or such other
counsel as shall be acceptable to the Company, in each case addressed and
delivered to the Company, the securities represented thereby need no longer be
subject to the restrictions contained in this Warrant.  The provisions of this
Warrant shall be binding upon all subsequent holders of certificates bearing
the above legend and shall also be applicable to all subsequent holders of this
Warrant.

                 (c)      RESTRICTIONS ON TRANSFER.

                 (1)      General Restrictions.  Notwithstanding any provisions
contained in this Warrant to the contrary, this Warrant and the related Warrant
Shares bearing the legend as provided in Section (b) of this Warrant shall not
be transferable except upon the conditions specified in this Section (c), which
conditions are intended, among other things, to insure compliance with the
provisions of the Securities Act in respect of the transfer of this Warrant or
of such Warrant Shares.  The registered holder of this





                                       2
<PAGE>   68
Warrant agrees that it will neither (i) transfer this Warrant prior to delivery
to the Company of the opinion of counsel referred to in, and to the effect
described in, Section (c)(2), or until registration hereof under the Securities
Act, nor (ii) transfer such Warrant Shares prior to delivery to the Company of
the opinion of counsel referred to in, and to the effect described in, Section
(c)(2), or until registration of such Warrant Shares under the Securities Act
has become effective.

                 (2)      Statement of Intention to Transfer: Opinion of
Counsel.  The registered holder of this Warrant, by its acceptance hereof,
agrees that prior to any transfer of this Warrant or any transfer of the
related Warrant Shares bearing the legend as provided in Section (b) of this
Warrant, said holder will deliver to the Company a statement setting forth
either said holder's intention with respect to the disposition of this Warrant
or of any Warrant Shares (whichever is involved in such transfer), in either
such case, together with a signed copy of the opinion of said holder's counsel
as shall be acceptable to the Company, as to the necessity or non-necessity for
registration under the Securities Act in connection with such transfer.  Each
such opinion shall either be addressed to the Company or state that the Company
may rely thereon.  The following provisions shall then apply:

         i.               If, in the opinion of said holder's counsel, the
                 proposed transfer of this Warrant or the proposed transfer of
                 such Warrant Shares may be effected without registration under
                 the Securities Act of this Warrant or such Warrant Shares, as
                 the case may be, then the registered holder of this Warrant
                 shall be entitled to transfer this Warrant or to transfer such
                 Warrant Shares in accordance with the statement of intention
                 delivered by said holder to the Company.

         ii.              If, in the opinion of said counsel, either the
                 proposed transfer of this Warrant or such Warrant Shares may
                 not be effected without registration under the Securities Act
                 of this Warrant or such Warrant Shares, as the case may be,
                 the registered holder of this Warrant shall not be entitled to
                 transfer this Warrant or such Warrant Shares, as the case may
                 be, until such registration is effective.

                 (d)      RESERVATION OF SHARES.  The Company shall at all
times reserve for issuance and/or delivery upon exercise of this Warrant such
number of shares of its Common Stock as shall be required for issuance and
delivery upon exercise of the Warrants.

                 (e)      FRACTIONAL SHARES.  No fractional shares or script
representing fractional shares shall be issued upon the exercise of this
Warrant.  With





                                       3
<PAGE>   69
respect to any fraction of a share called for upon any exercise hereof, the
Company shall pay to the Holder an amount in cash equal to such fraction
multiplied by the current market value of a share, determined as follows:

                          (1)     If the Common Stock is listed on a national
                 securities exchange or admitted to unlisted trading privileges
                 on such exchange or listed for trading on the Nasdaq National
                 Market, the current market value shall be the last reported
                 sale price of the Common Stock on such exchange or market on
                 the last business day prior to the date of exercise of this
                 Warrant or if no such sale is made on such day, the average
                 closing bid and asked prices for such day on such exchange or
                 market; or

                          (2)     If the Common Stock is not so listed or
                 admitted to unlisted trading privileges, but is traded on the
                 Nasdaq SmallCap Market, the current Market Value shall be the
                 average of the closing bid and asked prices for such day on
                 such market and if the Common Stock is not so traded, the
                 current market value shall be the mean of the last reported
                 bid and asked prices reported by the National Quotation
                 Bureau, Inc. on the last business day prior to the date of the
                 exercise of this Warrant; or

                          (3)     If the Common Stock is not so listed or
                 admitted to unlisted trading privileges and bid and asked
                 prices are not so reported, the current market value shall be
                 an amount, not less than book value thereof as at the end of
                 the most recent fiscal year of the Company ending prior to the
                 date of the exercise of the Warrant, determined in such
                 reasonable manner as may be prescribed by the Board of
                 Directors of the Company.

                 (f)      EXCHANGE, TRANSFER, ASSIGNMENT OR LOSS OF WARRANT.
This Warrant is exchangeable, without expense, at the option of the Holder,
upon presentation and surrender hereof to the Company or at the office of its
stock transfer agent, if any, for other warrants of different denominations
entitling the holder thereof to purchase in the aggregate the same number of
shares of Common Stock purchasable hereunder.  This Warrant is not transferable
other than by will or pursuant to the laws of descent and distribution and
except as provided under Subsection (c) hereof.  Upon surrender of this Warrant
to the Company at its principal office or at the office of its stock transfer
agent, if any, with the Assignment Form annexed hereto duly executed and funds
sufficient to pay any transfer tax, the Company shall, without charge, execute
and deliver a new Warrant in the name of the assignee named in such instrument
of assignment and this Warrant shall promptly be cancelled.  This Warrant may
be divided or combined with other warrants which carry the same rights upon
presentation hereof at the principal office of the Company or at the office of
its stock transfer agent, if any, together with a written notice specifying the
names and denominations in which new Warrants are to be issued and signed by
the





                                       4
<PAGE>   70
Holder hereof.  The term "Warrant" as used herein includes any Warrants into
which this Warrant may be divided or exchanged.  Upon receipt by the Company of
evidence satisfactory to it of the loss, theft, destruction or mutilation of
this Warrant, and (in the case of loss, theft or destruction) of reasonably
satisfactory indemnification, and upon surrender and cancellation of this
Warrant, if mutilated, the Company will execute and deliver a new Warrant of
like tenor and date.  Any such new Warrant executed and delivered shall
constitute an additional contractual obligation on the part of the Company,
whether or not this Warrant so lost, stolen, destroyed, or mutilated shall be
at any time enforceable by anyone.

                 (g)      RIGHTS OF THE HOLDER.  The Holder shall not, by
virtue hereof, be entitled to any rights of a shareholder in the Company,
either at law or equity, and the rights of the Holder are limited to those
expressed in the Warrant and are not enforceable against the Company except to
the extent set forth herein.

                 (h)      ANTI-DILUTION PROVISIONS.  The Exercise Price in
effect at any time and the number and kind of securities purchasable upon the
exercise of the Warrants shall be subject to adjustment from time to time upon
the happening of certain events as follows:

                          (1)     In case the Company shall (i) declare a
                 dividend or make a distribution on its outstanding shares of
                 Common Stock in shares of Common Stock, (ii) subdivide or
                 reclassify its outstanding shares of Common Stock into a
                 greater number of shares, or (iii) combine or reclassify its
                 outstanding shares of Common Stock into a smaller number of
                 shares, the Exercise Price in effect at the time of the record
                 date for such dividend or distribution or of the effective
                 date of such subdivision, combination or reclassification
                 shall be adjusted so that it shall equal the price determined
                 by multiplying the Exercise Price by a fraction, the
                 denominator of which shall be the number of shares of Common
                 Stock outstanding after giving effect to such action, and the
                 numerator of which shall be the number of shares of Common
                 Stock outstanding immediately prior to such action.  Such
                 adjustment shall be made successively whenever any event
                 listed above shall occur.

                          (2)     Whenever the Exercise Price payable upon
                 exercise of each Warrant is adjusted pursuant to Subsection
                 (1) above, the number of Shares purchasable upon exercise of
                 this Warrant shall simultaneously be adjusted by multiplying
                 the number of Shares initially issuable upon exercise of this
                 Warrant by the Exercise Price in effect on the date hereof and
                 dividing the product so obtained by the Exercise Price, as
                 adjusted.

<PAGE>   71
                          (3)     In the event that at any time, as a result of
                 an adjustment made pursuant to Subsection (1) above, the
                 Holder of this Warrant thereafter shall become entitled to
                 receive any shares of the Company, other than Common Stock,
                 thereafter the number of such other shares so receivable upon
                 exercise of this Warrant shall be subject to adjustment from
                 time to time in a manner and on terms as nearly equivalent as
                 practicable to the provisions with respect to the Common Stock
                 contained in Subsection (1) above.

                 (i)      REGISTRATION UNDER THE SECURITIES ACT OF 1933.

                          (1)     The Company shall advise the Holder of this
                 Warrant or of the Warrant Shares or any then holder of
                 Warrants or Warrant Shares (such persons being collectively
                 referred to herein as "holders") by written notice at least
                 two weeks prior to the filing of any registration statement or
                 post-effective amendment thereto under the Securities Act of
                 1933 covering securities of the Company and will for the
                 period until October 23, 2001, upon the request of any such
                 holder, include in any such registration statement such
                 information as may be required to permit a public offering of
                 the Warrant Shares.  In connection with its filing of any
                 registration statement or post-effective amendment thereto,
                 the Company shall supply prospectuses and other documents as
                 the Holder may request in order to facilitate the public sale
                 or other disposition of the Warrant Shares, qualify the
                 Warrant Shares for sale in such states as any such holder
                 designates and do any and all other acts and things which may
                 be necessary or desirable to enable such Holders to consummate
                 the public sale or other disposition of the Warrant Shares.

                          (2)      If any registration pursuant to Subsection 1
                 of this Section (i) shall be underwritten in whole or in part,
                 the Company may require that the Warrant Shares requested for
                 inclusion pursuant to Subsection 1 of this Section (i) be
                 included in the underwriting on the same terms and conditions
                 as the securities otherwise being sold through the
                 underwriters.  In the event that in the good faith judgment of
                 the managing underwriter of such public offering the inclusion
                 of all of the Warrant Shares covered by a request for
                 registration would reduce the number of shares to be offered
                 by the Company or interfere with the successful marketing of
                 the shares of stock offered by the Company, the number of
                 Warrant Shares otherwise to be included in the underwritten
                 public offering may be reduced pro rata (by number of shares)
                 among the holders thereof requesting such registration or
                 excluded in their entirety if so required by the underwriter.
                 To the extent only a portion of the Warrant Shares is included
                 in the underwritten public offering, those Warrant

                 Shares which are thus excluded from the underwritten public
                 offering shall be withheld from the market by the holders
                 thereof for a period, not to exceed 120 days, which the
                 managing underwriter reasonably determines is necessary in
                 order to effect the underwritten public offering.

                 The obligation of the Company under Subsection 2 of this
                 Section (i) shall be limited to two registration statements.

                          (3)     The Company shall bear the entire cost and
                 expense of any registration of securities initiated by it
                 under Subsection (1) of this Section (i) notwithstanding that
                 Warrant Shares may be included in any such registration.   Any
                 holder whose Warrant Shares are included in any such
                 registration statement pursuant to this Section (i) shall,
                 however, bear the fees of his own counsel and any registration
                 fees, transfer taxes or underwriting discounts or commissions
                 applicable to the Warrant Shares sold by him pursuant thereto.

                 2.  Designation of Nominees.

                 (a) Subject to Section 8 hereof:

                  (i) during the term of the Agreement the Ames Group shall
                 have the right to designate four nominees for election as
                 directors of Xplor (together, the "Ames Nominees", and
                 individually an "Ames Nominee").  The initial Ames Nominees
                 are Eugene L. Ames, Jr., John Y. Ames, James W. Gorman and
                 Jere W. McKenny who shall be elected directors of Xplor
                 effective upon the Closing under the Exchange Agreement and
                 take office as soon as permitted by Securities and Exchange
                 Commission Rule 14f-1;

                  (ii) the Blair Group shall have the right to designate two
                 nominees for election as directors of Xplor (together, the
                 "Blair Nominees", and individually a "Blair Nominee") for the
                 one year term commencing with the Annual Meeting to be held in
                 1997 and the right to designate one nominee for election as a
                 director of Xplor for the one year term commencing with the
                 Annual Meeting to be held in 1998.  The initial Blair Nominees
                 are Martin A. Bell and J. Morton Davis who are currently in
                 office and shall remain so when the Ames Nominees and the
                 Lomak Nominee take office as herein provided; and

                  (iii) during the term of the Agreement the Lomak Group shall
                 have the right to designate one nominee for election as a
                 director of Xplor (the  "Lomak Nominee").  The initial Lomak
                 Nominee is John H. Pinkerton who shall be elected a director
                 of Xplor effective upon the Closing under the





                                       2
<PAGE>   3
                 Exchange Agreement and take office as soon as permitted by
                 Securities and Exchange Commission Rule 14f-1.

                 (b)  The Blair Group, the Ames Group and the Lomak Group shall
each cause its nominees who are directors to nominate the designees as the
management slate of directors.

                 (c) At least 50 days prior to any meeting (or written action
in lieu of a meeting) of stockholders of Xplor at or by which directors are to
be elected, each party entitled to name Nominee(s) for director(s) of Xplor
shall notify the other such parties and Xplor in writing of such party's
Nominee(s) for election as director(s), together in each case with information
about such Nominee(s) necessary for Xplor to comply with applicable disclosure
requirements.  In the absence of any such notification, it shall be presumed
that the then incumbent Nominee(s) have been redesignated as the respective
party's Nominee(s).

                 3.  Voting.  (a)  From and after the date hereof, each of the
Ames Group, the Blair Group and the Lomak Group shall vote all Shares at each
meeting (or written action in lieu of a meeting) of stockholders of Xplor to
elect, as directors of Xplor the Nominees designated in the manner provided in
Section 2 and shall vote all Shares against any proposal having the effect of
increasing the Board of Xplor to more than seven directors.

                 4.  Successor Directors.  If a Nominee shall cease to serve as
a director for any reason, the party which designated such person shall have
the right to designate a successor Nominee and the parties shall use their best
efforts to ensure that such successor Nominee is duly elected as a director,
including causing its nominees who are directors so to vote.  If a party
notifies the other parties that such party desires to remove a director who
serves as such party's Nominee, the parties shall use their best efforts to
ensure that, consistent with Delaware law and the by-laws of Xplor, that such
director is duly removed as a director, if possible, or that a meeting of
stockholders of Xplor is promptly called for the purpose of electing a new
management slate of directors consistent with the designations of the parties
to this Agreement.

                 5.  Prohibited Transfers.  No member of the Ames Group or the
Lomak Group shall sell, assign, transfer otherwise dispose of all or any Shares
except as expressly provided in this Agreement or as otherwise consented to in
writing by the Ames Representative and the Lomak Representative.  Stratum
Shares may be transferred by the Ames Group as contemplated by the Letter
agreement between The New Venus Exploration, Inc. and Stratum Corp. dated April
25, 1997.  JWM Director Shares and/or JWG Director Shares, as the case may be
transferred without reference





                                       3
<PAGE>   4
to this Agreement, including Section 5, 6 and 7 hereof, at such time as Jere W.
McKenny or James W. Gorman, as the case may be, is no longer a director of
Xplor following his anticipated election as a director of Xplor.  Shares may be
pledged hypothecated, mortgaged or encumbered by members of the Ames Group or
the Lomak Group provided that document issued in connection therewith
specifically provides that the Rights of the holder thereof are subject to all
the terms of this Agreement.  Notwithstanding the foregoing, (a) members of the
Ames Group may transfer Shares to any other member of the Ames Group, and
members of the Lomak Group may transfer any or all of their Shares to one or
more "affiliates" of the Lomak Group (as such term is defined in Securities and
Exchange Commission regulations) in which event each such transferee shall be
bound by all of the provisions of this Agreement to the same extent as if such
transferee were a party hereto; and (b) members of the Ames Group who are
individuals may transfer any or all of their Shares (i) by way of gift to any
member of their respective families or to any trust for the benefit of any such
persons' family members or the person himself or herself, provided that any
such transferee shall agree in writing with the other parties hereto, as a
condition to such transfer, to be bound by all of the provisions of this
Agreement to the same extent as if such transferee were a party hereto, or (ii)
by will or the laws of descent and distribution, in which event each such
transferee shall be bound by all of the provisions of this Agreement to the
same extent as if such transferee were a party hereto.  As used herein, the
word "family" shall include any spouse, lineal ancestor or descendant, brother
or sister.

                 6.  Right of First Refusal.

                 (a) If at any time any member of the Ames Group or the Lomak
Group (a "Selling Stockholder") desires to sell its Shares (other than pursuant
to a transfer permitted pursuant to Section 5 hereof) pursuant to a bona fide
offer from a third party (the "Proposed Transferee"), the Selling Stockholder,
if a member of the Ames Group shall submit a written offer (the "First Offer")
to sell such Shares (the "Offered Shares") to the Lomak Representative and, if
a member of the Lomak Group to the Ames Representative on behalf of their
respective groups ("Non-Selling Stockholders") on terms and conditions,
including price, not less favorable to the Non-Selling Stockholders than those
on which the Selling Stockholder proposes to sell such Offered Shares to the
Proposed Transferee.  The First Offer shall disclose the identity of the
Proposed Transferee, the number of Offered Shares proposed to be sold, the
total number of Shares owned by the Selling Stockholder, the terms and
conditions, including price, of the proposed sale, and any other material facts
relating to the proposed sale.  Non-Selling Stockholders may acquire, in
accordance with the provisions of this Agreement, all but not any portion of
the Offered Shares for the price and upon the other terms and conditions,
including deferred payment (if applicable), set forth therein.





                                       4
<PAGE>   5
                 (b) If a Non-Selling Stockholder desire to purchase the
Offered Shares, the Non-Selling Stockholder shall communicate in writing its
election to purchase to the Selling Stockholder, within 7 days of the date the
First Offer was made.  Such communication shall, when taken in conjunction with
the First Offer, be deemed to constitute a valid, legally binding and
enforceable agreement for the sale and purchase of such Offered Shares.  Sales
of the Offered Shares to be sold to the Non-Selling Stockholders pursuant to
this Section 6 shall be made at the offices of the Selling Stockholder on the
12th day following the date the First Offer was made (or if such 12th day is
not a business day, then on the next succeeding business day).  Such sales
shall be effected by the Selling Stockholder's delivery to the Non-Selling
Stockholder of a certificate or certificates evidencing the Offered Shares to
be purchased by it, duly endorsed for transfer to such Non-Selling Stockholder,
against payment to the Selling Stockholder of the purchase price therefor by
such Non-Selling Stockholder.

                 (c) If the Non-Selling Stockholders do not elect to purchase
the Offered Shares, the Offered Shares may be sold by the Selling Stockholder
at any time within 30 days after the date the First Offer was made, subject to
the provisions of Section 6 and 7.  Any such sale shall be to the Proposed
Transferee, at not less than the price and upon other terms and conditions, if
any, not more favorable to the Proposed Transferee than those specified in the
First Offer.  Any remaining Shares not sold within such 30-day period shall
continue to be subject to the requirements of prior offers pursuant to this
Section 6.  If Offered Shares are sold pursuant to this Section 6 to any person
who is not a party to this Agreement, the Offered Shares so sold shall no
longer be subject to any of the restrictions imposed by this Agreement.

                 (d)  Notwithstanding the foregoing subsections (a) through (c)
of this Section 6. if a Selling Stockholder wishes to sell Shares pursuant to
Rule 144 (or its successor provision), the Non-Selling Stockholder shall have
the right, exercisable within 7 business days following receipt of a Form 144
notice of sale, to purchase the Shares subject to such notice at the closing
price of the Shares on the first trade date immediately before the date of the
filing of such notice.  If any Non-Selling Shareholder elects to purchase such
Shares the closing will be effected within 3 business days following its
election to purchase.  If the Non-Selling Shareholder elect not to purchase,
the Selling Shareholder shall be free to sell the Shares covered by the notice
for a period of 30 days thereafter.

                 7.  Right of Participation in Sales by Ames Group or Lomak 
Group.

                 (a) If at any time member(s) of the Ames Group or members of
the Lomak Group ("Participation Seller") desire to sell in the aggregate
thirty-five percent or more of the Participation Seller's then outstanding
ownership of Shares for cash or other consideration (other than pursuant to a
transfer permitted pursuant to Section 5 hereof) to any third party (the
"Buyer"), the other party, i.e. the Ames Group or The Lomak





                                       5
<PAGE>   6
Group, as the case may be (the "Other Party") shall have the right to sell to
the Buyer, as a condition to such sale by the Participation Seller, at the same
price per share and on the same terms and conditions as involved in such sale
by the Participation Seller, the same percentage of the Shares owned by the
Other Party as the Shares to be sold by the Participation Seller to the Buyer
represents with respect to the Shares owned by the Participation Seller
immediately prior to the sale of any of such Participation Seller's Shares to
the Buyer.  The obligation hereunder with respect to a party shall cease at
such time as that party owns less than 5% of the then outstanding shares of
Xplor.

                 (b) The Other Party shall notify the Participation Seller in
writing of such intention as soon as practicable and in any event within ten
business days after the date the First Offer was made.  Such notification shall
be given to such Participation Seller in accordance with Section 10 below.

                 (c) The Participation Seller and the Other Party shall sell to
the Buyer all, or at the option of the Buyer, any part of the Shares proposed
to be sold by them at not less than the price and upon other terms and
conditions, if any, not more favorable to the Buyer than those in the First
Offer provided by the Participation Seller under Section 6 above; provided,
however, that any purchase of less than all of such Shares by the Buyer shall
be made from the Participation Seller and the Other Party, pro rata, based upon
the relative amount of the Shares that the Participation Seller and the Other
Party is otherwise entitled to sell pursuant to Section 7(a).

                 (d) Any Shares sold by  the Participation Seller or the Other
Party pursuant to this Section 7 shall no longer be subject to this Agreement.

                 8.  Term.  This Agreement shall continue through the third
anniversary of the date of this Agreement, provided, that the rights and
obligations of any party hereunder shall cease at such time that such party
owns beneficially fewer than 250,000 Shares.

                 9.  Specific Enforcement.  Each of parties hereto expressly
agrees that the other parties will be irreparably damaged by a breach of this
Agreement if this Agreement is not specifically enforced.  Upon a breach or
threatened breach of the terms, covenants and/or conditions of this Agreement
by any party, a non-breaching party shall, in addition to all other remedies,
be entitled to a temporary or permanent injunction, without showing any actual
damage, and/or a decree for specific performance, in accordance with the
provisions hereof.

                 10.  Notices.  All notices or other communications given
hereunder shall be in writing and shall be deemed effective upon delivery at
the address of the party to be notified and shall be mailed by certified or
registered mail, return receipt requested, delivered by courier, telecopied, or
sent by other facsimile method (notices by telecopy





                                       6

or facsimile must be confirmed by next day courier delivery to be effective),

other address as such party may subsequently notify the other parties of in
writing.

                 11.  Entire Agreement and Amendments.  This Agreement
constitutes the entire agreement of the parties with respect to the subject
matter hereof and neither this Agreement nor any provision hereof may be
waived, modified, amended or terminated except by a written agreement signed by
Xplor, and to the extent that the Ames Group, the Blair Group and/or the Lomak
Group still have the right to have designees on the Board of Directors pursuant
to Section 2, the Ames Representative, the Blair Representative and/or the
Lomak Representative, as the case may be

                 12.  Designation of Representatives; Power of Attorney.  Each

respectively by his, her or its execution of this Agreement, hereby irrevocably
constitutes, appoints and designates the Ames Representative, Blair
Representative, the Lomak Representative respectively, named above as his, her

                                    Recitals

       A.     Each of the Shareholders represents that he or she is the owner
of the number of shares of capital stock The New Venus Exploration, Inc.,
called the "Company", set forth opposite his or her name above.

       B.     In order to provide for the smooth and efficient operation of the
Company, to prevent conflicts, and to avoid deadlocks, the Shareholders deem it
to be in the best interest of the Company and all of its shareholders that this
agreement be executed.

       For these reasons, the Shareholders, in consideration of their mutual
promises, agree with each other and with the Trustee, and the Trustee agrees
with the Shareholders, as follows:

       Section One.  Transfer of Stock to Trustee.  Each Shareholder will
deposit the number of shares of capital stork set forth opposite his or her
name above and the certificates representing those shares, together with
sufficient instruments executed for their transfer to the Trustee, with the
Trustee, and will receive in exchange trust certificates.  On the making of
that deposit, all shares represented by the stock certificates so deposited
will be transferred on the books of the Company to the name of the Trustee, who
is authorized and empowered to cause such transfers to be made, and also to
cause any further transfers to be made that may become necessary due to a
change in the identity of any trustee or trustees as provided here.

       Section Two.  Trustee's Control Over Stock.  During the period this
agreement remains in force, the Trustee will possess legal title to the shares
deposited and will be entitled to exercise all rights whatsoever, including the
right to vote in person or by proxy, in respect of any and all deposited
shares.  Each holder of a trust certificate issued by the Trustee will be
entitled to receive payments equal to any and all dividends collected by the
Trustee with respect to shares of stock deposited by the holder of that trust
certificate.

       Section Three.  Voting Trust Certificate.  Upon deposit by any
Shareholder of a certificate or certificates for shares of stock under this
agreement, accompanied by instruments of transfer, the Trustee will deliver or
cause to be delivered to the Shareholder, a voting trust certificate or
certificates for the same number of shares of stock as may be represented by
the certificate or certificates deposited.

       The voting trust certificates will be in substantially the following
form:

                           Voting Trust Certificate


                               VENUS ENERGY PLC

No.                                                                    Shares
     ---------                                    --------------------

This certifies that ______________ has deposited ____________ shares of the
capital stock of The New Venus Exploration, Inc., with the undersigned, as
Trustee, under a voting trust agreement dated March 23, 1997, between the
holders of capital stock of The New Venus Exploration, Inc., and E. L. Ames,
Jr., and his successors, as Trustee.  This certificate and the interest
represented is transferable only on the books of the Trustee and only on its
presentation and surrender to the Trustee.  The holder of this certificate
takes it subject to all the terms and conditions of the voting trust agreement
and becomes a party to such agreement and is entitled to its benefits.

       Executed by the undersigned as Trustee on ___________________ [date].



                                                                                
                                                  ------------------------------
                                                  E. L. Ames, Jr., Trustee


       Section Four.  Additional Stock.  After this agreement has taken effect,
the Trustee may, from time to time, receive any additional fully paid shares of
the capital stock of the Company on the same terms and conditions as are set
forth in this agreement.  In respect of all shares so received, the Trustee
will issue and deliver certificates substantially in the form set out above,
entitling the holder to all the rights specified above.

       Section Five.  Dividends.  All dividends that may accrue on the
deposited stock must be distributed pro rata among the holders of the voting
trust certificates in the proportion they are entitled.

       Section Six.  Sale of Stock and Certificates by Shareholders.  During
the period from the date of this agreement until the second anniversary of the
first day the Company's shares are freely tradeable on a recognized stock
exchange or market pursuant to the Company's initial public offering, but not
later than July 1, 2000, the Shareholders agree, and the Trustee accepts this
trust only on the condition, that the Shareholders will not sell their
equitable interests in their respective shares in a manner that would remove
those shares from the effect of this agreement.  However, the voting trust
certificates may be sold, pledged or mortgaged, but every assignee or
transferee of a voting trust certificate issued under this agreement will, by
the acceptance of such certificate, become a party to this agreement, with the
same effect as though an original subscriber to the agreement, and the Trustee
will continue to have all rights granted to it pursuant to this agreement.
Irrespective of the foregoing, the Shareholders acknowledge that all the shares
of the Company are





                                      -3-
<PAGE>   4
presently restricted shares and are not freely tradeable or transferable.  Only
when the Trustee has been supplied with such evidence as he may require, in his
sole discretion, that a transfer of any of the shares or certificates may be
made under, and in accordance with, the rules and laws of the all applicable
governments and agencies, including, without limitation, the U.S. federal and
state securities laws and regulations, will any request for a new such voting
certificate be considered.  If that evidence has not been supplied and accepted
by the Trustee for any reason, no Shareholder will request a new certificate,
nor will the Trustee be under any duty to deliver same.

       Section Seven.  Rights of Trustee.  During the period this agreement
remains in effect, the Trustee will possess and will be entitled to exercise,
in person or by proxy, all rights and powers of absolute ownership in respect
of all the stock of the Company deposited with him, including the right to vote
on, to take part in, and consent to, any corporate or shareholders' election or
action of any kind whatsoever, and to receive dividends and distributions on
the stock.  The Trustee's right to vote will include the right to vote for the
election of directors and in favor of, or in opposition to, any resolution or
proposed action of any character whatsoever that may require the consent of
shareholders.

       Section Eight.  Successor Trustee.  In the event that E. L. Ames, Jr.,
is no longer capable of serving as Trustee or no longer desires to serve as
Trustee, John Y. Ames, E. L. Ames III and Elizabeth Ames Jones, shall be
requested to serve as Co-Trustees, and if they accept, they shall serve as
