Item 2.  Acquisition or Disposition of Assets

         On March 11, 1996, Rio Grande Drilling Company  ("Drilling"),  a wholly
owned subsidiary of Rio Grande, Inc. (the "Company'),  acquired a 3.125% working
interest in an existing  producing  federal oil and gas lease in South Timbalier
Area, Block 76,  OCS-G-4460  ("Block 76") offshore  Louisiana for an acquisition
price of $900,000. The acquisition includes an interest in the offshore platform
which is currently  accommodating a gas well flowing at a rate of  approximately
16,000 Mcf of gas and 1,100  barrels of  condensate  per day, net to  Drilling's
interest.  Funds for the  acquisition  were  borrowed from Comerica Bank - Texas
("Comerica")  pursuant to the new senior credit facility  described in Item 5 of
this report. The summary description of the acquisition of Block 76 is qualified
in its entirety by reference to the Closing  Agreement,  which is attached as an
exhibit to this report.


Item 5.  Other Events

         On March 8, 1996,  the Company and Drilling  executed a loan  agreement
with  Comerica  which  provides a new senior  credit  facility  in an  aggregate
principal  amount  of up to  $10,000,000.  The  maturity  date for  this  credit
facility is February 1, 1998.  The initial  available  credit  under this credit
facility is $4,967,000. This credit facility was used to refinance the Company's
and Drilling's  existing senior indebtedness of $1,575,000 on March 11, 1996 and
provide  $900,000 to purchase Block 76 on the same date. The Company  intends to
use the  remaining  available  credit  under this  credit  facility  to fund two
additional  acquisitions scheduled for closing at the end of March and the first
week of April  1996.  The  payment  terms  under the credit  facility  initially
require the Company to make eleven (11)  monthly  principal  payments of $82,000
commencing  April 1, 1996 and then eleven  (11)  monthly  principal  payments of
$108,833 commencing March 1, 1997. The remaining principal  outstanding shall be
due and payable on February 1, 1998, the maturity date of the loan. The interest
rate to be charged on the outstanding  principal  balance is based on Comerica's
prime rate plus 1%. All of the Company's interests (direct or indirect) existing
oil and gas properties,  miscellaneous  assets,  and future oil and gas property
acquisitions  will serve as collateral  for the credit  facility.  The preceding
summary  of the  terms of  credit  facility  is  qualified  in its  entirety  by
reference  to the  Loan  Agreement  evidencing  this  credit  facility  which is
attached as an exhibit to this report.

         Comerica's  commitment to provide the Company and Drilling a new credit
facility required that the Company request certain  modifications and amendments
from the holders of the Company's and Drilling's  $2,000,000 in principal amount
of 11.50%  Subordinated  Notes due September  30, 2000 (the "Notes")  before the
Comerica loan agreement  could be executed.  The Company  submitted a request to
the  holders  of Notes  and  subsequently  obtained  unanimous  consents  to the
proposed amendments.

         The  following is a summary of certain  amendments to the Note Purchase
Agreement,  which  summary is  qualified  in its  entirety by  reference  to the
complete text of the amendments which appear as exhibits to this report:

         1.       Amendment of the repayment terms of the Notes to provide for a
                  final maturity on September 30, 2002 (instead of September 30,
                  2000) and the quarterly  amortization  of principal  over four
                  years,  commencing in December 1998, at annual rates of 12.5%,
                  12.5%,  37.5%  and  37.5%  of the  original  principal  amount
                  (instead  of  amortization  of  principal  over  three  years,
                  commencing in December  1997, at annual rates of 12.5%,  37.5%
                  and 50% of the original principal amount).



                                     Page 2





         2.       Amendment  of  the  provisions  pertaining  to  remedies  upon
                  default  to  provide  for a 120 day  period  within  which the
                  holders  of Notes  would not be able to  initiate,  join in or
                  consent  to a  bankruptcy  petition  against  the  Company  or
                  Drilling.

         3.       Amendment  of  certain  definitions  and  related  clauses  to
                  clarify  and  confirm  that (i)  Comerica's  loan would be the
                  senior  bank  indebtedness,  and  (ii)  reserves  owned by Rio
                  Grande  Offshore,  Ltd.  (an  affiliate  of  the  Company  and
                  Drilling)  are  eligible  as being  "Qualified  Reserves"  for
                  purposes of the Note Purchase Agreement.  These clarifications
                  are  consistent  with  the  original  intent  of the  Company,
                  Drilling and the holders of Notes.

         4.       Amendment to the  definition  of  "Qualified  Reserves"  which
                  provides a mechanism for valuing newly  acquired  reserves for
                  the purpose of  determining  the  "Qualified  Reserves  Value"
                  under the Note Purchase Agreement.

         5.       Amendment of provisions pertaining to permitted liens to allow
                  a  temporary  second lien in favor of Comerica on a portion of
                  certain  reserves  scheduled  to be acquired by the Company in
                  the first week of April, 1996.

         6.       Amendment to add a consent by the holders of Notes to the loan
                  from Comerica.

         7.       Amendment to reflect the  reduction  in the exercise  price of
                  the warrants  granted on September  27, 1995 to the holders of
                  Notes in connection with the Note Purchase Agreement from $.40
                  per share to $.20 per share.

         In addition to the amendments required by Comerica,  certain additional
consents  were  required  to change  the  partnership  structure  of Rio  Grande
Offshore,  Ltd.  and to  provide  an  alternate  source  of  financing  for  the
acquisition of Block 76. The following is a summary of consents which summary is
qualified in its entirety by reference to the complete  text of these  consents,
which are attached as exhibits to this report.

         1.       Consent to a  restructuring  of Rio Grande  Offshore,  Ltd. by
                  distributing  undivided interests in the onshore properties to
                  the  existing  limited  partners  and  transferring   existing
                  offshore properties to a new partnership,  Rio Grande GulfMex,
                  Ltd.

         2.       Consent  to  a  possible  interim  loan,   guaranty  or  other
                  accommodation  by  Robert A.  Buschman  or  another  affiliate
                  should it become  necessary  to provide  interim  financing to
                  make the initial acquisition of Block 76.

Item 7.  Financial Statements and Exhibits

                  (a)      Financial Statements

                           Because  the  historical  financial  records  for the
                           acquisition of Block 76 were not accessible  from the
                           seller prior to the closing date, it is impracticable
                           to provide the required financial  statements for the
                           acquisition  at the time this Form 8-K is filed.  The
                           Company  anticipates  that the financial  information
                           relative to the Block 76 acquisition will be combined
                           with the  financial  information  filed with the Form
                           10-KSB due on or before April 30, 1996.

                                                            Exhibit 4.3  Page 1

                      AMENDMENTS TO NOTE PURCHASE AGREEMENT

         (1) The  definition  of  "Bank  Indebtedness"  set  forth  in the  Note
Purchase Agreement is amended to read as follows (changes indicated):

         "Bank Indebtedness" means the indebtedness  evidenced by and/or arising
         under  the Loan  Agreement  dated  July  14,  1994 by and  between  the
         Companies and International  Bank of Commerce,  and evidenced by and/or
         arising under any promissory notes or other loan documents  executed in
         connection  with and/or  modifying or amending  said Loan  Agreement or
         extending such promissory  notes, if any. The term "Bank  Indebtedness"
         also includes any indebtedness  under a loan from Comerica Bank - Texas
         to the Companies and/or their Subsidiaries  secured by a first priority
         lien on all or part of the Property  owned by the  Companies  and/or by
         one or more of their  Subsidiaries  upon  substantially  the  terms set
         forth in the loan  commitment  letter from  Comerica  Bank-Texas to the
         Companies dated March 1, 1996.

         (2)  The   definitions  of   "Non-Recourse   Indebtedness,"   "Recourse
Indebtedness" and "Qualified  Reserves" set forth in the Note Purchase Agreement
are amended to read as follows (changes indicated):

         "Non-Recourse  Indebtedness"  with  respect  to any  Person  means  any
         Indebtedness of such Person with respect to which the liability of such
         Person is limited  solely to the  property,  assets or contract  rights
         securing such Indebtedness.

         "Qualified  Reserves" means all proved developed producing reserves and
         all  proved  developed  nonproducing  reserves  owned by  either of the
         Companies or by any Subsidiary,  either directly or indirectly  through
         the ownership of an interest in a partnership  that owns such reserves,
         as set forth in the most recent  Reserve Report (which shall be no less
         frequent than annual);  provided,  however, that any such reserves upon
         which there is a lien securing  Indebtedness of either of the Companies
         or of any Subsidiary  which is  Non-Recourse  Indebtedness as to all of
         such Persons (i.e., the Companies or their Subsidiaries) who are liable
         on, or whose  property  secures,  such  Indebtedness  are not  included
         within  the term  "Qualified  Reserves."  The terms  "proved  developed
         producing reserves" and "proved developed  nonproducing reserves" shall
         have the meaning  given such terms from time to time and at the time in
         question  by  the  Society  of  Petroleum  Engineers  of  the  American
         Institute  of Mining  Engineers.  With respect to such  reserves  owned
         indirectly by either of the Companies or by any Subsidiary  through the
         ownership of an interest in a partnership that owns such reserves, such
         reserves  considered  to be owned by the  Companies  or the  Subsidiary
         shall be such  reserves  owned by such  partnership  multiplied  by the
         percentage  ownership  of such  partnership  owned by the  Companies or
         their  Subsidiaries.  In the event that the Companies or any Subsidiary
         should  acquire any  additional  proved  developed  producing  reserves
         and/or  proved  developed  non-producing  reserves  in the  future in a
         single  transaction or series of  transactions  within an annual period
         following  the  preparation  of a Reserve  Report,  the  Companies  may
         designate  such  reserves as Qualified  Reserves,  having the Qualified
         Reserves Value  ascribed to them by the Companies in good faith,  using
         reasonable  industry  standards,  up to a maximum additional  Qualified
         Reserves Value of one million dollars ($1,000,000.00), for the





                                                            Exhibit 4.3  Page 2

         purposes of  determining  the Qualified  Reserves  Value until the next
         scheduled  Reserve  Report  is  delivered.   If  the  Companies  should
         designate a Qualified  Reserves Value in excess of one million  dollars
         ($1,000,000.00)  for proved developed  producing reserves and/or proved
         developed   non-producing   reserves  acquired  in  any  single  future
         transaction or series of transactions within an annual period following
         the preparation of a Reserve  Report,  such reserves shall be deemed to
         be Qualified  Reserves,  with the Qualified  Reserves Value ascribed to
         them  by the  Company  until  the  next  scheduled  Reserve  Report  is
         delivered for the purpose of determining the Qualified  Reserves Value;
         provided,  however,  that within  thirty (30) days after Closing of the
         transaction causing such additional  Qualified Reserves to increase the
         Qualified  Reserves  Value reported in the last prior Reserve Report by
         at least one  million  dollars  ($1,000,000.00),  the  Companies  shall
         deliver to the Holders  compliance  certificates  in the form  attached
         hereto  as  Exhibit  10.7,  executed  by an  officer  of  the  Company,
         certifying that the ratio of the Recourse Indebtedness to the Qualified
         Reserves Value does not exceed 75% on the date of such certificate.

         "Recourse  Indebtedness"  means  any  Indebtedness  of  either  of  the
         Companies  or  any  Wholly-Owned  Subsidiary  other  than  Non-Recourse
         Indebtedness of such Persons,  excluding,  however, any Indebtedness of
         either  of the  Companies  owed to any  Wholly-Owned  Subsidiary  or to
         Offshore and any  Indebtedness of any  Wholly-Owned  Subsidiary owed to
         either of the Companies or to any other  Wholly-Owned  Subsidiary or to
         Offshore.

         (3) Section 11.3 of the Note  Purchase  Agreement is amended to read as
follows (changes indicated):

         11.3.    Liens.

         The Companies  will not create,  incur,  or suffer to exist any Lien on
         any of their properties, except the following which shall be "Permitted
         Liens": (i) Liens for taxes,  assessments,  or governmental  charges or
         levies on their properties,  provided the same shall not at any time be
         delinquent  or  thereafter  can be paid  without  penalty  or are being
         contested in good faith and by appropriate proceedings and with respect
         to which reserves in conformity with GAAP have been adequately provided
         for on the books of the  Companies;  (ii) Liens imposed by law, such as
         carriers',  warehouseman's and mechanic's liens and other similar Liens
         arising in the ordinary  course of their  business which secure payment
         of obligations  not more than 60 days past due; (iii) Liens arising out
         of pledges or deposits under workman's compensation laws,  unemployment
         insurance,  old age  pensions,  or other Social  Security or retirement
         benefits,  or similar  legislation;  (iv) Liens  resulting from utility
         easements,  building  restrictions,  and  such  other  encumbrances  or
         charges against real property as of are of a nature generally  existing

         such Holder of a Note shall not take a  Bankruptcy  Enforcement  Action
         until the  earlier  to occur of (i) the  period of time  stated in such
         Standstill  Notice,  and (ii) 120 days  from the date  such  Standstill
         Notice is given by such holder of Senior Indebtedness to such Holder of
         a Note.  A Holder of a Note shall not be required to give the holder of

         Bank  may  have,  all  pursuant  to the  terms  of one or more  deposit

         commencing  with the  period  ending  August 1,  1996,  and  continuing
         quarterly thereafter.

determination thereof, an amount as determined by Bank in its sole discretion in
accordance with then-current practices,  customary procedures and standards used

such  reserve  and  production  data with  respect to the Mineral  Interests  of
Grantors  in all of  their  oil  and gas  properties,  including  the  Mortgaged
Properties,  as is provided to Bank in accordance  herewith.  The Borrowing Base
shall initially be $4,967,000.

                  3.1 Periodic  Determinations  of Borrowing Base. The Borrowing
         Base  shall  be  redetermined  by Bank as of  February  1 of each  year
         commencing  February  1,  1997  (each a  "Determination  Date"),  until
         maturity.  The Borrowing Base, as redetermined,  shall remain in effect
         until the next Determination  Date,  provided the Borrowing Base may be
         redetermined between Determination Dates in accordance with Section 3.3
         hereof.

                  3.2  Engineering  Data  to  be  Provided  Prior  to  Scheduled
         Determination  Dates.  On or  before  January  1 of each  year  for the

         production  and  other  engineering  data for the oil and gas  reserves
         attributable  to the Mineral  Interests of Grantors in all of their oil
         and gas properties, updated and supplemented from that contained in the
         most recent Reserve Report furnished to Bank. Bank shall then determine
         the Borrowing Base for the one (1) year period commencing February 1.

                  3.3  Special   Determinations   of  Borrowing  Base.   Special
         determinations  of the Borrowing  Base may be requested by Borrowers or
         Bank at any time during the term hereof.  If any special  determination
         is requested by Borrowers, it shall be accompanied by engineering data





                                                           Exhibit 10.2  Page 5

         determination  is requested by Bank,  Borrowers  will provide Bank with
         the  information  similar to that contained in a Reserve Report as soon
         as is  reasonably  possible  following the request.  The  determination
         whether to increase or decrease the  Borrowing  Base shall then be made
         by Bank in its sole  discretion  in  accordance  with the standards set
         forth in Section 3.0 hereof. In the event of any special  determination
         of the Borrowing Base pursuant to this Section, Bank in the exercise of
         its discretion  may suspend or reschedule the next regularly  scheduled
         determination of the Borrowing Base.

                  3.4 Borrowing Base Deficiency.  If by reason of any adjustment
         to  the  Borrowing  Base,  the  principal  balance  of  the  Note  then
         outstanding  exceeds the amount of the Borrowing  Base, then Bank shall
         notify  Borrowers of the same,  and Borrowers  shall within thirty (30)
         days  following  receipt of such notice elect  whether to (i) prepay an
         amount which will reduce the principal amount of the Note to the amount
         of the  Borrowing  Base,  or (ii) execute and  deliver,  or cause to be
         executed  and  delivered,  to Bank  instruments  mortgaging  such other
         collateral  as is acceptable  to Bank,  pursuant to security  documents
         acceptable to Bank having present values which, in the opinion of Bank,
         taken in the aggregate are sufficient to increase the Borrowing Base to
         an amount at least equal to the  then-outstanding  principal balance of
         the Note, or (iii) do any combination of the foregoing as is acceptable
         to Bank.  If  Borrowers  so elect to  mortgage  additional  oil and gas
         properties,  then  clause  (ii)  above  shall  be  accomplished  within
         forty-five  (45) days from Bank's date of  notification.  If  Borrowers
         fail to make an election  among  clauses (i) through (iii) above within
         thirty  (30) days from Bank's  notification,  then  Borrowers  shall be
         deemed to have  selected  the payment  option  specified  in clause (i)
         thereof.

                  3.5 Monthly  Borrowing Base  Reduction.  The Borrowing Base in
         effect from time to time shall reduce automatically on the first day of
         each  month  commencing  April 1,  1996,  and  continuing  through  and
         including  January 1,  1998,  in the  amount of the  Monthly  Reduction
         Amount. Upon any determination of the Borrowing Base, Bank reserves the
         right to revise the Monthly Reduction Amount as it deems appropriate in
         accordance  with  then  current  practices,  customary  procedures  and
         standards  used  by  Bank  for  its  petroleum   customers   generally,
         consistently  applied  with  respect to  petroleum  industry  customers
         similarly situated. If by reason of the reduction of the Borrowing Base
         pursuant  to this  Section  3.5 the  Principal  Debt  then  outstanding
         exceeds the Borrowing Base as reduced,  then  Borrowers  shall promptly
         pay an amount which will reduce the Principal Debt then  outstanding to
         an amount equal to or less than the Borrowing Base as so reduced.

         4.0  Conditions  Precedent to Closing.  The  obligations of Bank as set

waived in writing by Bank, of each of the following conditions:

                  opinion.

                           (c) Grantors'  operating interest in such oil and gas

         favorable opinion of Borrowers'  counsel covering such matters incident
         to  the  Loan  as  Bank  may  reasonably  request,   including  without
         limitation an opinion to the substantive effect that the closing of the
         transactions  contemplated by the Loan Documents will not constitute an
         event of default under the Note Purchase Agreement.

                  4.9  Amendments to Note Purchase  Agreement.  Borrowers  shall
         have  delivered  to  Bank  true  and  correct  copies  of one  or  more

         affecting  either the  financial  condition  of the  Grantors or any of
         their Mineral Interests in the Mortgaged Properties.

modifications   of  or  consents   or  waivers   under  or   amendments   to  or
interpretations  of or enforcement of this  Agreement,  the Note, the other Loan
Documents  and the  agreements  described  therein.  Borrowers  further agree to
indemnify  Bank  from  and  hold  it  harmless   against  any  and  all  losses,
liabilities,  claims,  damages or  expenses  which  Bank  suffers or incurs as a
result  of  its  entering  into  this  Agreement,  or  the  consummation  of the
transactions  contemplated by this Agreement and the Loan Documents,  or the use
or contemplated use of the proceeds of the Loan, including,  without limitation,
the  fees  and   disbursements  of  counsel  incurred  in  connection  with  any
litigation,  arbitration or other proceeding  arising out of or by reason of any
of the aftersaid.

         13.0  Miscellaneous.  Borrowers and Bank further  covenant and agree as
follows, without limiting any requirement of any other Loan Document:

                  13.1  Cumulative  Rights and No Waiver.  Each and every  right
         granted to Bank under any Loan Document, or allowed it by law or equity
         shall be  cumulative  of each other and may be exercised in addition to
         any and all other rights of Bank,  and no delay in exercising any right
         shall  operate  as a waiver  thereof,  nor shall any  single or partial
         exercise  by Bank of any right  preclude  any other or future  exercise
         thereof or the exercise of any other right.  Borrowers  expressly waive
         any presentment, demand, protest or other notice of any kind, including
         but not  limited  to  notice  of intent  to  accelerate  and  notice of
         acceleration. No notice to or demand on Borrowers in any case shall, of
         itself,  entitle  Borrowers to any other or future  notice or demand in
         similar or other circumstances.

                  13.2  Applicable  Law.  This  Agreement  and  the  rights  and
         obligations  of  the  parties   hereunder  shall  be  governed  by  and
         interpreted in accordance with the laws of Texas and applicable  United
         States federal law.

                  13.3 Amendment. No modification,  consent, amendment or waiver
         of any  provision of this  Agreement,  nor consent to any  departure by
         Borrowers  therefrom,  shall be  effective  unless the same shall be in
         writing and signed by an officer of Bank,  and then shall be  effective
         only in the  specified  instance  and for the purpose for which  given.
         This Agreement is binding upon Borrowers, their successors and assigns,
         and inures to the benefit of Bank, its successors and assigns; however,
         no assignment or other  transfer of  Borrowers'  rights or  obligations
         hereunder  shall be made or be effective  without  Bank's prior written
         consent,  nor shall it relieve Borrowers of any obligations  hereunder.
         There is no third party beneficiary of this Agreement.

                  13.4 Documents.  All documents,  certificates  and other items
         required under this Agreement to be executed  and/or  delivered to Bank
         shall be in form and content satisfactory to Bank and its counsel.






                                                          Exhibit 10.2  Page 17

                  13.5 Partial Invalidity. The unenforceability or invalidity of
         any provision of this Agreement shall not affect the  enforceability or
         validity  of  any  other   provision   herein  and  the  invalidity  or
         unenforceability of any provision of any Loan Document to any person or
         circumstance  shall not affect the  enforceability  or validity of such
         provision as it may apply to other persons or circumstances.

                  13.6 Survivability. All covenants, agreements, representations
         and warranties made herein or in the other Loan Documents shall survive
         the making of the Loan and shall  continue  in full force and effect so
         long as the Loan is  outstanding  or the obligation of Bank to make any
         advances hereunder shall not have expired.

         14.0  Joint and  Several  Liability  of  Borrowers.  The  liability  of
Borrowers hereunder shall be joint and several in all respects.

         15.0 Limitation on Liability of Subsidiaries.  Notwithstanding anything
to the contrary contained in any of the Loan Documents,  and except as expressly
hereinafter  provided,  but  without  in  any  manner  releasing,  impairing  or
otherwise affecting the Note or any of the other Loan Documents, or the validity
thereof or hereof, or the liens created thereby,  or the liability of Borrowers,
in the event of any default under the terms of the Note or any of the other Loan
Documents,   the  liability  of  the  Subsidiaries  for  the  repayment  of  the
indebtedness  evidenced  by the Note or for any other  sums due as the result of
any  defaults  under the Note or of any of the other  Loan  Documents,  shall be
limited  to  the  Mineral   Interests  of  the  Subsidiaries  in  the  Mortgaged
Properties.  The limitations of liabilities  specified in the preceding sentence
shall not  apply in the  following  circumstances  (provided  nothing  contained
herein  shall be  construed  to impose  upon any  Subsidiary  liability  for the
repayment of borrowed money without such liability being limited to the property
securing the repayment of such borrowed money):

                  A. Fraud or Misrepresentation. The Subsidiaries shall be fully
         liable for fraud or misrepresentation made by any Grantor in connection
         with the Loan Documents to which they are parties.

                  B.  Failure  to Pay Taxes and  Assessments.  The  Subsidiaries
         shall be fully liable for taxes, assessments or other charges which can
         create  liens  on any  portion  of the  Mortgaged  Properties  that are
         payable or  applicable to a period prior to any  foreclosure  under any
         Oil and Gas  Mortgage  (but only to the full  extent of any such taxes,
         assessments or other charges not so paid).


         16.0  Agreement  Controlling.  In the event of a conflict  between  the
terms and  provisions of this  Agreement and the terms and  provisions of any of
the other Loan  Documents,  the terms and  provisions  of this  Agreement  shall
control.  The parties  understand and agree that the  commitment  letter between
them dated as of March 1, 1996  (executed by the Borrowers as of March 2, 1996),
has been replaced and superseded by this Agreement.

         17.0 Notice of Final Agreement.  THIS WRITTEN 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.

Attn:  Division Order Department

         Re:      Letter-in-Lieu of Transfer and Division Order

Gentlemen:

         You are currently purchasing the oil and/or gas production from each of
the  properties  identified (by well name and your lease  identification  and/or
division order number) in Exhibit A attached hereto (collectively,  the "Subject
Properties").   In  connection  therewith,  you  are  currently  making  monthly
settlement to Rio Grande Drilling Company, Rio Grande Offshore, Ltd., and/or Rio
Grande GulfMex, Ltd. (collectively, the "Grantor").

         This will constitute  formal notice to you that Grantor has executed in
favor of Comerica  Bank - Texas (the  "Lender")  previous  mortgages and related
security  agreements  which  create  liens and  security  interests  against the
ownership interests of Grantor in each of the Subject  Properties.  Each of such
mortgages also contains an express  assignment from Grantor to the Lender of all
proceeds  attributable  to the  sale of  production  attributable  to  Grantor's
ownership interests in each of the Subject Properties.  At your request,  copies
of each of such mortgages (with applicable  recordation  data) will be furnished
for your files.

         Grantor and Lender request that you change your records to begin making
payment to the Lender (for the account of Grantor) for the interest, as shown on
Exhibit A, for the properties for which you are purchasing  production and which
you have  previously  credited to Grantor,  effective as of 7:00 a.m.,  March 1,
1996, at the address set forth below:

                           COMERICA BANK - TEXAS
                           1601 Elm Street, 2nd Floor
                           Dallas, Texas  75201
                           Attention:  Energy Lending

Because the payments to be made by you to the Lender as requested  above are for
the account of Grantor,  please  continue to use  Grantor's  tax  identification
number in making such payments.






                                                          Exhibit 10.2  Page 36



         You are not  authorized  to mail checks or make  payments for Grantor's
interests in the Subject  Properties  to any address  other than that  specified
above unless and until  expressly  instructed to do so by prior  written  notice
executed by the Lender.

         In consideration for your reliance upon this Letter-in-Lieu of Transfer
Order and Division Order,  Grantor and the Lender will indemnify you against and
hold you  harmless  from any  character  of claim,  damage or loss  which may be
asserted against or sustained by you as a result of your reliance hereon.

         Although  the   effectiveness  of  this  letter  and  your  obligations
hereunder are not dependent upon your acceptance of this letter, Grantor and the
Lender  request that you  acknowledge  receipt of this letter by  executing  the
enclosed  duplicate  counterpart  in the space below and returning such enclosed
duplicate  counterpart  to the Lender in the  self-addressed  envelope  included
herewith.

         Should you have any questions  relative to these  instructions,  please
telephone Mr. Terry O. McCarter, Vice President of the Lender at 214/965-8984.

                                        Very truly yours,
