Item 6.           Management's Discussion and Analysis or Plan of Operation


Results of Operations

            This  discussion  should be read in  conjunction  with the financial
statements of the Company and the notes thereto included in this Form 10-KSB.

            Oil and gas sales  decreased  to $126,286  in 1995 from  $164,982 in
1994.  This  represents  a decrease of $38,696 or 23%.  Oil sales  decreased  by
$4,405 or 10%. A 6% decrease in oil  production  caused  revenues to decrease by
$2,942.  A 3%  decrease  in the  average  oil net sales  price  caused  sales to
decrease by an additional  $1,463.  Gas sales decreased by $34,291 or 29%. A 14%
decrease  in gas  production  reduced  sales by $16,340.  A 17%  decrease in the
average gas net sales price reduced sales by an additional $17,951.  The changes
in oil and gas  production  were  primarily  the  result of  natural  production
declines, which were especially pronounced on the Wardner Ranch acquisition. The
decreases  in the average oil and gas net sales  prices  were  primarily  due to
higher operating expenses incurred on the FEC acquisition,  in which the Company
has a net profits  royalty  interest,  coupled  with lower prices in the overall
market for the sale of gas,  partially  offset by higher  prices in the  overall
market for the sale of oil.

            Depletion  expense  decreased  to $99,390 in 1995 from  $114,225  in
1994.  This  represents a decrease of $14,835 or 13%. The changes in production,
noted  above,  reduced  depletion  expense  by  $13,712.  A 1%  decrease  in the
depletion rate reduced depletion expense by an additional  $1,123.  The decrease
in the depletion rate was due to an upward revision of oil reserves during 1995,
partially offset by a downward revision of the gas reserves during 1995.

            General and  administrative  expenses  decreased  to $18,247 in 1995
from $25,770 in 1994.  This  decrease of $7,523 or 29% was primarily due to less
staff time being  required to manage the  Company's  operations  coupled  with a
$1,444 decrease in direct costs incurred by the Company in 1995. The decrease in
direct expenses was due to lower audit and tax preparation  fees incurred by the
Company in 1995.

Capital Resources and Liquidity

   
            The  Company's  cash flow from  operations is a direct result of the
amount  of net  proceeds  realized  from  the  sale of oil  and gas  production.
Accordingly, the changes in cash flow from 1994 to 1995 are primarily due to the
changes  in oil  and gas  sales  described  above.  It is the  general  partners
intention to distribute  substantially  all of the Company's  available net cash
flow provided by operating,  financing and investing activities to the Company's
partners. Distributions decreased from 1994 to 1995 primarily as a result of the
decrease in revenues, noted above.
    

            The Company will continue to recover its reserves and  distribute to
the partners the net proceeds  realized from the sale of oil and gas  production
after payment of debt obligations. The Company plans to repay the amount owed to
the general partner over a three year period.  Distribution  amounts are subject
to change if net revenues are greater or less than  expected.  Nonetheless,  the
general partner  believes the Company will continue to have sufficient cash flow
to fund operations and to maintain a regular pattern of distributions.

ENEX 90-91 INCOME AND RETIREMENT FUND - SERIES 1, L.P.


NOTES TO FINANCIAL STATEMENTS
FOR THE TWO YEARS ENDED DECEMBER 31, 1995
----------------------------------------------------------------------------


1.           PARTNERSHIP ORGANIZATION

             Enex  90-91  Income  and  Retirement   Fund  Series  1,  L.P.  (the
             "Company"), a New Jersey limited partnership,  commenced operations
             on September  11, 1990 for the purpose of  acquiring  non-operating
             interests  in  producing  oil and  gas  properties.  Total  limited
             partner  contributions  were  $1,487,600,   of  which  $14,876  was
             contributed by Enex  Resources  Corporation  ("Enex"),  the general
             partner.

             In  accordance  with the  partnership  agreement,  the Company paid
             syndication  fees  and  due  diligence  expenses  of  $143,049  for
             solicited   subscriptions   to  Enex  Securities   Corporation,   a
             subsidiary of Enex, and reimbursed Enex for  organization  expenses
             of approximately $52,000.

             The Company owns only non-operating  interests in producing oil and
             gas  properties.  Such interests  typically  entitle the Company to
             receive its pro rata share of net profits  and  royalties  from the
             underlying  properties without obligating the Company to develop or
             operate the properties or directly bear any share of development or
             operating costs.

             Information  relating  to the  allocation  of  costs  and  revenues
             between Enex, as general  partner,  and the limited  partners is as
             follows:
                                                                      Limited
                                                            Enex      Partners

             Commissions and selling expenses                           100%
             Company reimbursement of organization
               expenses                                                 100%
             Company property acquisitions                              100%
             General and administrative costs                10%         90%
             Revenues from temporary investment
               of partnership capital                                   100%
             Revenues from producing properties              10%         90%


             At the point in time  when the cash  distributions  to the  limited
             partners  equal  their  subscriptions  ("payout"),   revenues  from
             producing  properties and general and administrative  costs will be
             allocated  15% to  the  general  partner  and  85%  to the  limited
             partners.

2.           SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

             Oil and Gas  Properties - The Company uses the  successful  efforts
             method of accounting  for its oil and gas  operations.  Capitalized
             costs are  amortized  on the  units-of-production  method  based on
             estimated total proved  reserves.  The acquisition  costs of proved
             oil and gas properties are  capitalized and  periodically  assessed
             for impairments.

                                      II-8

             The Financial  Accounting  Standards Board has issued  Statement of
             Financial   Accounting  Standards  No.  121,  "Accounting  for  the
             Impairment  of Long Lived  Assets and for  Long-Lived  Assets to Be
             Disposed Of." This statement  requires that  long-lived  assets and
             certain  identifiable  intangibles  held and used by the Company be
             reviewed for impairment whenever events or changes in circumstances
             indicate  that  the  carrying   amount  of  an  asset  may  not  be
             recoverable.

             The Company has not determined the effect, if any, on its financial
             position  or  results  of  operations  which  may  result  from the
             adoption of this statement in the first quarter of 1996.

             Organization  Costs  -  Organization  costs  were  amortized  on  a
             straight-line   basis  over  a  five-year  period  and  were  fully
             amortized at December 31, 1995.

             Cash Flows - The  Company  has  presented  its cash flows using the
             indirect method and considers all highly liquid investments with an
             original maturity of three months or less to be cash equivalents.

             General and  Administrative  Expenses - The Company  reimburses the
             General Partner for direct costs and administrative  costs incurred
             on its behalf.  Administrative  costs  allocated to the Company are
             computed  on a cost  basis in  accordance  with  standard  industry
             practices  by  allocating  the time spent by the General  Partner's
             personnel  among  all  projects  and by  allocating  rent and other
             overhead on the basis of the relative direct time charges.

             Uses of Estimates - The preparation of the financial  statements in
             conformity with generally accepted  accounting  principles requires
             management  to make  estimates  and  assumptions  that  affect  the
             reported  amounts  of assets  and  liabilities  and  disclosure  of
             contigent  assets  and  liabilities  at the  date of the  financial
             statements and the reported  amounts of revenue and expenses during
             the  reporting  periods.  Actual  results  could  differ from these
             estimates.

3.           FEDERAL INCOME TAXES

             General - The Company is not a taxable  entity for  federal  income
             tax purposes. Such taxes are liabilities of the individual partners
             and the  amounts  thereof  will vary  depending  on the  individual
             situation of each partner.  Accordingly,  there is no provision for
             income taxes in the accompanying financial statements.

4.           PAYABLE TO GENERAL PARTNER

             The payable to general  partner  primarily  consists of general and
             administrative expenses allocated to the Company by Enex during the
             Company's  start-up  phase  and for  its  ongoing  operations.  The
             Company plans to repay the amounts owed to the general partner over
             a period of three years.

5.           REPURCHASE OF LIMITED PARTNER INTERESTS

             In accordance with the partnership  agreement,  the general partner
             is required to purchase limited partner interests (at the option of
             the  limited  partners)  at annual  intervals  beginning  after the
             second year  following the  formation of the Company.  The purchase
             price,  as  specified  in  the  partnership  agreement,   is  based
             primarily  on reserve  reports  prepared by  independent  petroleum
             engineers  as reduced by a  specified  risk  factor.  For the first
             three annual purchase offers,  the general partner's  obligation is
             limited to the lesser of 10% of the total partnership's  capital or
             profits.

6.           SIGNIFICANT PURCHASERS

             Union Pacific Resources  accounted for 85% and 86% of the Company's
             total  sales in 1995 and  1994,  respectively.  No other  purchaser
             individually accounted for more than 10% of such sales.
