                  RE:      Amendment of First  Amended and Restated  Loan
                         Agreement  dated  September 23, 1996, as
                           amended,  among  Saba  Petroleum  Company et al. and
                          Bank One,  Texas,  N.A.  (the "Loan
                           Agreement")

Dear Mr. Vance:

                  Saba  Petroleum  Company  ("Saba")  has  asked  that Bank One,
Texas, N.A. ("Bank One") consent to the Preferred Stock Sale transaction (herein
called the  "Transaction")  that is  outlined  on the Final  Summary of Offering
dated  December  15,  1997 (the  "Summary  of  Offering"),  which is attached as
Exhibit "A" to the form of consent letter that is attached  hereto as Schedule 1
(the "Consent  Letter"),  and extend the maturity dates of the Term Note and the
Mezzanine Note. Bank One is willing to do so, subject to the following terms and
conditions.

                  1.       Consent. Upon  satisfaction of the conditions set
forth in paragraph 2 hereof,  Bank One shall contemporaneously execute and
deliver the Consent Letter to Saba.

                  2.       Conditions to Consent.

                           a.       Closing of the  Transaction.  The Consent
Letter and the  amendments set forth herein are effective and  conditioned  upon
the contemporaneous closing of the Transaction.

                           b.       Transaction  Documents.  Bank  One's
execution  and  delivery  of the  Consent
Letter is further  conditioned  on Saba's  representation,  and Saba does hereby
represent,  that: (i) the Summary of Offering substantially  describes the terms
of the  Transaction  insofar as it relates to dividends  payable with respect to
the Preference Shares (as defined in the Summary of Offering) and the redemption
of the Preference  Shares,  and (ii) there are no variances between the terms of
the definitive documentation to be executed by Saba to implement the Transaction
and those set forth in the Summary of Offering that would materially,  adversely
affect either Saba's  Obligations to Bank One, Bank One's rights with respect to
Saba, or Bank One's  remedies  upon the  occurrence of an Event of Default or an
Unmatured Event of Default.

                           c.       Application  of Proceeds.  Contemporaneously
with Saba's  consummation  of the
Transaction,  Saba shall pay to Bank One the principal sum of $7,000,000.00,  to
be credited to the outstanding  principal  balance of the Term Loan evidenced by
the Term Note, together with a fee in the amount of $113,755.38 (being 2% of the
principal  balance  remaining  under  the  Term  Note  and  the  Mezzanine  Note
subsequent to the effective date of this Amendment),  as  consideration  for the
consents, waivers and amendments agreed to herein by Bank One, and the remaining
proceeds,  net of  direct  costs  associated  with this  transaction,  are to be
applied  within thirty (30) days to trade payables  incurred in connection  with
Borrower's operation and development of its oil and gas properties

                           d.       Beaver  Lake  Resources.  Saba  agrees  that
 the pledge of its  interest in the
Beaver Lake stock, the escrow agreement relating thereto, and the Sabacol stock,
as provided in the Fifth  Amendment,  shall,  within ten (10) Business Days from
the date hereof,  be fully  perfected  and  implemented  as set forth in Section
3.17(d) and (e) and Section  5.36 of the Loan  Agreement,  as added by the Fifth
Amendment.

                  3. Amendment of Maturity Dates. Saba and Bank One hereby agree
that the Mezzanine Loan Maturity Date is amended from January 2, 1998, to become
April 30, 1998,  and that the Term Loan  Maturity  Date is amended from December
31, 1997, to become April 30, 1998.

                  4.       Article V shall be amended by adding the following
new Section 5.37:

                  5.37 Special Principal Payments. The Borrower shall reduce the
                  outstanding  principal  balance  of  the  Term  Loan  and  the
                  Mezzanine  Loan by a total of $3,000,000 on or before April 1,
                  1998  and,  on or  before  June  1,  1998,  shall  reduce  the
                  outstanding  principal  balance of the remaining  Indebtedness
                  owed to Bank One by an additional  amount equal to the greater
                  of: (a) $3,000,000;  or (b) an amount sufficient to reduce the
                  balance of  Borrower's  outstanding  Indebtedness  to Bank One
                  plus the unfunded Revolving  Commitment to such an amount that
                  can be fully repaid by the net cash flow projected by Bank One
                  to be  received  by  Borrower  from  the  sale  of oil and gas
                  produced  from  the  Borrowing  Base  Properties   within  the
                  Economic  Half  Life  of  the  Borrowing  Base  Properties  as
                  determined  by Bank  One,  in its sole  discretion,  using its
                  then-prevailing  credit  criteria,  exclusive  of the required
                  reductions of the Borrowing Base described in Section 2.03.

                  5. Other  Amendments  to Loan  Documents.  Saba agrees that it
shall  cooperate  and  negotiate in good faith with Bank One  subsequent  to the
execution  of this  Agreement  in order  to  reach  agreement,  and  enter  into
documentation  in  form  and  substance  satisfactory  to  Bank  One,  regarding
additional amendments to the following provisions of the Loan Agreement:

                           a.       Section 5.34 shall be amended to take into

account the payment  credited to the
Term Loan pursuant to this Amendment, and to adjust the obligations with respect
to the  application of future funds raised by Saba as between the Mezzanine Loan
and the Term Loan.

                  If  requested  by Bank One,  Saba shall,  and Saba shall cause
each of its Subsidiaries  that are parties to the Loan Agreement to,  authorize,
approve  and enter  into,  on or before  January  31,  1998,  a more  definitive
amendment document and any implementing  documentation  contemplated thereby, in
order to more fully set forth and/or implement the provisions of this Amendment.

                  6. Ratification of Guaranties.  Each Guarantor hereby ratifies
and confirms its liability  under the Guaranty  heretofore  executed by it, and,
except as stated to the  contrary in this  paragraph,  confirms  and agrees that
such  Guaranty  continues  in full force and effect  with  respect to all of the
Indebtedness  covered  by the  Loan  Agreement,  as the  same  may be  restated,
amended, modified,  renewed, or rearranged from time to time, including, but not
limited  to,  the  Indebtedness  evidenced  by the  Note,  the Term Note and the
Mezzanine Note; provided,  however, that the Guaranty of Sabacol relates only to
the  Indebtedness  evidenced by the Term Note and the  Mezzanine  Note,  and the
Guaranty of Ilyas Chaudhary  relates only to the  Indebtedness  evidenced by the
Mezzanine Note and the Term Note. This  ratification is given for the purpose of
inducing Bank One to enter into this Amendment and each Guarantor is aware that,
but for such  ratification and agreement  contained  herein,  Bank One would not
enter into this Amendment.

                  7. Reaffirmation of Representations and Warranties.  To induce
Bank One to enter into this Amendment, Saba and each Guarantor hereby reaffirms,

                           b.       The  Loan   Agreement  as  amended  by  this
   Amendment  and  each   Guaranty,
respectively,  as ratified  hereby,  represent the respective  legal,  valid and
binding obligations of Saba and each respective  Guarantor,  enforceable against

as  hereby  further  amended  and the other  documents  previously  executed  or
executed of even date herewith.

                  11.  Governing  Law. THIS  AMENDMENT  SHALL BE GOVERNED BY AND

counterpart  if  sent  to  any  other  party  hereto  by  electronic   facsimile
transmission.

instruments and documents comprising the Written Loan Agreement.  Saba, Bank One
and the Guarantors each warrant and represent that the entire agreement made and
existing by or among Saba, Bank One and the Guarantors with respect to the Loans

hereby,  and that no  agreements  or promises  have been made by, or exist by or
among,  Saba, Bank One and Guarantors that are not reflected in the Written Loan
Agreement. THE WRITTEN LOAN AGREEMENT REPRESENTS THE FINAL AGREEMENT BETWEEN THE
PARTIES AND MAY NOT BE  CONTRADICTED BY EVIDENCE OF PRIOR,  CONTEMPORANEOUS,  OR
SUBSEQUENT  ORAL  AGREEMENTS  OF  THE  PARTIES.  THERE  ARE  NO  UNWRITTEN  ORAL
AGREEMENTS BETWEEN THE PARTIES.

                  18.      Event of Default.  It shall  constitute an Event of
