          J. Morton Davis,  D.H.  Blair  Investment  Banking Corp.  ("Blair
          Investment"),  Rosalind Davidowitz, Rivkalex Corporation ("Rivkalex"),
          and Parliament  Hill  Corporation  ("PHC",  joining as a joint filer),
          (collectively,  the  "Reporting  Parties")  hereby amend the following
          Items in their statement on Schedule 13D relating to the common stock,
          $.01 par value  ("shares")  of Xplor  Corporation  (the  "Issuer")  as
          follows:

Item 2. (a) is hereby amended by adding the following sentence thereto:

          This statement is also filed on behalf of Parliament Hill 
          Corporation ("PHC").

Item 2. (b) is hereby amended by adding the following sentence thereto:

          PHC's business address is P.O. Box 1522, New York, NY  10268.

Item 2. (c) is amended in its entirety as follows:

          Mr. Davis is an investment banker and sole shareholder of Blair
          Investment, a broker-dealer registered under the Securities
          Exchange Act of 1934.

          Rivkalex (4) is a privately-held  New York corporation  formed to
          invest in, hold, and sell securities of other  companies.  It is owned
          by Rosalind Davidowitz, Mr. Davis' wife, who is President.

          PHC is a private  corporation of which Rosalind  Davidowitz  owns
          approximately 72.6% and Blair Investment owns approximately 13.4%.

Item 2. (d) and 2 (e) are hereby amended by inserting PHC, after Ms. Davidowitz.

Item 4. is hereby  partially  amended by deleting the first sentence therein and
adding the following at the beginning of Item 4.:

          On May 21, 1997, the Issuer closed the transactions  contemplated
          by a certain Property  Acquisition  Agreement (the "PAA") entered into
          on April 29, 1997, an  unexecuted  copy of which is filed as Exhibit G
          hereto and is  incorporated  herein by  reference,  with the New Venus
          Exploration,  Inc.  ("Venus")  and Lomak  Production  I L.P. and Lomak
          Resources,  L.L.C. (together, the "Lomak Parties"),  pursuant to which
          the  Issuer  purchased  substantially  all of the  assets of Venus and
          certain  properties  from the Lomak  Parties in exchange for shares of
          the Issuer 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 Issuer and warrants to purchase an additional
          272,353 shares. Venus will hold such shares 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.  The Lomak Parties  received  2,037,171 shares and
          warrants to purchase an  additional  272,353  shares.  Pursuant to the
          terms of the PAA,  Eugene L. Ames, Jr., Ellen R.Y. Ames, John Y. Ames,
          Elizabeth A. Jones,  Eugene L. Ames, III,  Stephen J. Ames,  George J.
          Ames, Carl Oliver, Patrick A. Garcia, Raymond M. Koger, Gloria Barret,
          Venus  Oil   Company,   James  W.   Gorman,   and  Jere  W.   McKenney
          (collectively,  the "Ames  Parties"),  the  Reporting  Parties and the
          Lomak Parties (collectively,  the "SA Parties") entered into a certain
          Stockholders'  Agreement  dated May 21, 1997 (the "SA"), an unexecuted
          copy of which is filed as Exhibit H hereto and incorporated  herein by
          reference,  pursuant  to which,  among  other  things,  the SA Parties
          agreed to vote  together on the  election of  directors  and agreed to
          certain  restrictions  upon the sale of shares held by the SA Parties.
          The descriptions of the 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
          G  and  Exhibit  H,  respectively,  and  are  incorporated  herein  by
          reference.

Item 4 (continued)

          The  Reporting  Parties will review on a  continuous  basis their
          investment in the Issuer's  shares and the Issuer's  business  affairs
          and  financial  condition,  as well as  conditions  in the  securities
          markets and general  economic and industry  conditions.  The Reporting
          Parties  may in the  future  take such  actions  in  respect  of their
          investment in the Issuer's shares 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  Reporting  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 Reporting  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  described  herein may be made at any time
          without  further  prior notice.  In reaching any  conclusion as to the
          foregoing  matters,  the  Reporting  Parties and the Lomak Parties may
          take into consideration various factors, such as the Issuer's business
          and  prospects,   other   developments   concerning  the  Issuer,  the

          opportunities  available to the Reporting  Parties,  general  economic
          conditions, the market price for shares and stock market conditions.

          that the name of the Issuer should be changed. It is expected that the
          name of the Issuer will be changed to Venus Exploration,  Inc., within
          a reasonable time after the date hereof.

effective at the close of business on the Closing  Date,  provided  that certain

                                   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

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

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.

                  (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
or other  provision  therefor,  except as appropriate  and consistent  with past
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 Xplor Stock;
(vi) any issuance of any stock, bonds, options,  warrants or other 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.

or,  to the best  knowledge  of  Xplor,  investigation  pending  or, to the best
knowledge of

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

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.

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

     (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 such real
property, free and clear of all Encumbrances (except Permitted Encumbrances);

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

properties  and  rights,  including  all  such  assets,  properties  and  rights
reflected in the Xplor 10-K as well as such of like kind and

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

this Section 2.14, XPLOR 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

Schedule  AAA 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 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
that has been  furnished to Venus and the Lomak  Entities by Xplor 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,  Xplor 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
of, or  related  to,  Xplor's  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  2.16.  Brokerage  Fees.  Xplor 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
transaction  contemplated hereby or any transaction of like nature that would be
required to be paid by Xplor.

     Section  2.17.  Indebtedness.  Except as described in Schedule  2.17 to the

                  Section 2.18.  Taxes

                  (a)  Except  as set  forth on  Schedule  2.18(a)  to the Xplor

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 adjustments

Xplor may be liable, (C) established  reserves that are adequate for the payment
of all Taxes not yet due and payable with  respect to the results of  operations

any applicable  state or local taxing authority have been paid, fully settled or
adequately provided for in Xplor's most recent audited financial statements.  No

Taxes has been  proposed,  asserted  or assessed  pursuant  to such  examination
against Xplor by any federal,  state or local taxing  authority  with respect to
any period other than as set forth in Schedule  2.18(a) to the Xplor  Disclosure
Schedule.

                  (c) Xplor 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

having the effect of extending the period for  assessments  or collection of any
federal,  state or local  income or  franchise  Taxes for which  Xplor  would be
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 Xplor.

                  (d) Xplor 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.

liabilities pursuant to this Agreement.

                  Section 2.21. No Vote Required.  No vote of the holders of any
class or series of Xplor  capital  stock is necessary to approve the issuance of

                     REPRESENTATIONS AND WARRANTIES OF VENUS

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

                  Section 3.01.  Organization,  Etc. Venus is a corporation duly
organized,  validly existing and in good standing under the laws of the State of
Texas 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. Venus 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 3.01 to the Venus Disclosure  Schedule sets
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
and the Lomak Entities true and correct copies of its respective  Certificate of
Incorporation  (and other  documents  of record with the  Secretary  of State of
Texas) and Bylaws as in effect on the date  hereof.  Schedule  3.01 to the Venus
Disclosure  Schedule  sets forth a list of the officers and directors of each of

officers of Xplor  following  the  Closing  required by SEC Rule 14f-1 under the
Exchange Act.

                  Section 3.02.  Capitalization.

         The authorized capital stock of Venus consists of 400,000,000 shares of

Redeemable Preference Shares (par value of $0.001 per share). No shares of Venus
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 Venus are as set forth in  Venus's
Certificate of  Incorporation or otherwise of record with the Secretary of State
of   Texas,   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 Venus
Stock  have been duly  authorized  and  validly  issued  and are fully  paid and
non-assessable.  All of the  outstanding  shares of Venus  Stock were  issued in
compliance with all applicable  Federal and state  securities  laws. None of the
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 Venus
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
Venus is a party or by which Venus is bound,  obligating Venus to issue, deliver
or sell, or cause to be issued,  delivered or sold,  contingently  or otherwise,
additional  shares of capital stock of Venus 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 other, of Venus to purchase, redeem or otherwise acquire any capital stock of
Venus.  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 Venus'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 Venus 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 Venus Stock.

                  Section 3.03. Authorization. Venus 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 respective  obligations under
this  Agreement  and each of the other  agreements  contemplated  hereby  and to
consummate the transactions  contemplated hereby and thereby.  The execution and

performance by Venus of its  obligations  hereunder have been duly authorized by
all necessary corporate action except Venus Stockholder Approval. This Agreement
has been duly executed and delivered by Venus; 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 Venus,  enforceable
against  Venus  in  accordance  with its  terms,  subject  to Venus  Stockholder
Approval.

                  Section 3.04. No Violation. The execution and delivery of this
Agreement by Venus does not, and the  consummation by Venus 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 Certificate
of  Incorporation  (or other  documents of record with the Secretary of State of
Texas) 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

Venus 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

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

notes)  fairly  present  the  financial  position  of Venus 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

principles, requirements, rules and regulations.

                  Section 3.07.  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 Venus (ii) any adverse  change in the
assets or liabilities  or in the business or condition,  financial or otherwise,

establishment  of any reserve for taxes or any other liability on Venus 's books
or other  provision  therefor,  except as appropriate  and consistent  with past
practice; (iv) any change by Venus in tax methods, principles or elections or in
accounting  methods or principles  that would be required to be disclosed  under

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 Venus,  including,  but not limited
to, any sale, lease or other  disposition of properties and assets of Venus, and
any merger or  consolidation  of Venus with any other entity,  other than in the
ordinary  course of business and consistent with past practices and, to the best
knowledge of Venus, no fact or condition exists or is contemplated or threatened
which could reasonably be anticipated to cause such a change in the future.

                  Section   3.08.   Litigation.   There  is  no  action,   suit,
arbitration,  proceeding  or,  to the best  knowledge  of  Venus,  investigation
pending or, to the best knowledge of Venus,  threatened  against or affecting or
involving Venus 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 ("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

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 37 of 89 pages

                  (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.

     (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

                  (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

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

a material fact and do not omit to state any material fact necessary to make the

other  Person  under  any  statute,  law,  rule,  regulation,  permit,  license,
agreement,  indenture or other  instrument to which Production or Resources is a

                  (a) The Lomak Entities have delivered to Xplor and Venus true,

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.

                  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

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.

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)  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 Lomak Reserve Report with respect to such Lease; and

                  (iii) be free and clear of all liens, Encumbrances (except for

                  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

                  (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).

Section 2 and shall vote all Shares  against any  proposal  having the effect of
increasing the Board of Xplor to more than seven directors.

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

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

                  (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

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.
