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

NOTES TO UNAUDITED FINANCIAL STATEMENTS

1.    The interim financial  information included herein is unaudited;  however,
      such  information  reflects all adjustments  (consisting  solely of normal
      recurring adjustments) which are, in the opinion of management,  necessary
      for a fair presentation of results for the interim periods.

2.    A cash distribution was made to the limited partners of the Company in the
      amount of $14,017,  representing net revenues from the sale of oil and gas
      produced from properties owned by the Company.  This distribution was made
      on January 31, 1995.

3.    The Financial Accounting Standards Board has issued Statement of Financial
      Accounting  Standard  ("SFAS") No. 121,  "Accounting for the Impairment of
      Long-Lived  Assets and for  Long-Lived  Assets to be  Disposed  Of," which
      requires  certain assets to be reviewed for impairment  whenever events or
      circumstances indicate the carrying amount may not be recoverable.  In the
      first  quarter of 1996,  the  Company  recognized  a  non-cash  impairment
      provision  of $29,056  for certain  oil and gas  properties  due to market
      indications that the carrying amounts were not fully recoverable.







Item 2Management's Discussion and Analysis or Plan of Operation.

First Quarter 1996 Compared to First Quarter 1995

Oil and gas  sales for the  first  quarter  increased  from  $31,028  in 1995 to
$38,685  in 1996.  This  represents  an  increase  of  $7,657  (25%).  Oil sales
decreased  by $333 or 3%. A 16%  decrease  in oil  production  reduced  sales by
$1,843.  This decrease was partially offset by a 16% increase in average net oil
sales  prices.  Gas sales  increased by $7,990 or 41%. A 48% increase in average
net gas sales prices  increased  sales by $8,918.  This  increase was  partially
offset  by a 5%  decrease  in gas  production.  The  decreases  in oil  and  gas
production  were primarily due to natural  production  declines.  The changes in
average net prices correspond with changes in the overall market for the sale of
oil and gas.

Depletion expense decreased from $26,566 in the first quarter of 1995 to $22,630
in the first quarter of 1996.  This  represents a decrease of $3,936 (15%).  The
changes in production,  noted above,  reduced  depletion expense by $2,113. A 7%
decrease  in the  depletion  rate  reduced  depletion  expense by an  additional
$1,823.  The  decrease  in the  depletion  rate was  primarily  due to the lower
property basis resulting from the recognition of a $29,056  property  impairment
recognized in the first quarter of 1996.

The  Financial  Accounting  Standards  Board has issued  Statement  of Financial
Accounting  Standard  ("SFAS")  No.  121,  "Accounting  for  the  Impairment  of
Long-Lived  Assets and for Long- Lived Assets to be Disposed Of," which requires
certain assets to be reviewed for impairment  whenever  events or  circumstances
indicate the carrying  amount may not be  recoverable.  In the first  quarter of
1996,  the Company  recognized  a non-cash  impairment  provision of $29,056 for
certain  oil and gas  properties  due to market  indications  that the  carrying
amounts were not fully recoverable.

General and  administrative  expenses decreased from $4,422 in the first quarter
of 1995 to $3,463 in the first  quarter of 1996.  This decrease of $959 (22%) is
primarily  due to less  staff  time  being  required  to  manage  the  Company's
operations in 1996,  partially  offset by a $1,199  increase in direct  expenses
incurred by the Company in 1996.

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 1995 to 1996 are  primarily  due to the changes in oil
and  gas  sales  described  above.  It is the  general  partner's  intention  to
distribute  substantially  all of  the  Company's  available  cash  flow  to the
Company's partners.

The Company will continue to recover its reserves and  distribute to the limited
partners the net proceeds realized from the sale of oil and gas production after
payment of its debt obligations.  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.
