                                     PART I

Item 1.      Description of Business

General

             Enex  88-89  Income  and  Retirement  Fund - Series  4,  L.P.  (the
"Company")  was formed  under the New Jersey  Uniform  Limited  Partnership  Act
(1976) on  September  20,  1988 and  commenced  operations  on May 10, 1989 with
aggregate subscriptions of $1,822,413, $1,804,189 of which was received from 406
limited  partners,   including   investors  whose   distributions  from  earlier
partnerships   sponsored  by  the  Company's  general  partner,  Enex  Resources
Corporation ("Enex"), were automatically invested in the Company.

             The  Company  is engaged in the oil and gas  business  through  the
ownership of  non-operating  interests in producing  oil and gas  properties  as
noted in Item 2, below. A non-operating  interest  typically entitles the holder
to receive a specified share of such production,  without  obligation to develop
or operate such  property,  or bear any  development  or  operating  costs (such
obligations being assumed by the owner of the working interest in the property).

             The Company's  non-operating interests are net profits royalties or
other royalty  interests  which entitle the Company to a share of gross revenues
from producing oil and gas properties measured by a specified  percentage of the
net profits realized by the owners of the underlying  working  interests in such
properties,  after deducting operating costs,  geological and engineering costs,
property,  severance and other taxes, and certain other specified  expenses.  If
such taxes,  operating  costs or other  expenses  exceed  gross  revenues in any
specified  measuring period, a net profits royalty holder will not be liable for
payment of any portion of such excess,  but a percentage of such excess equal to
the specified percentage of net profits (together with interest thereon) will be
carried over to subsequent  periods and will reduce future  amounts  accruing to
the  holder.  The  Company's  net  profits  royalties  and  other  non-operating
interests are generally derived from working interests in oil and gas properties
owned by other affiliates of Enex.

             The  Company  owns   royalty   interest  on  certain  oil  and  gas
properties.  A "royalty  interest" is the interest retained by the lessor in the
lease and payable out of 100% of proceeds before deducting any other interests.

             The  Company  does not own  working  interests  nor does it  engage
directly in any drilling,  completing or operating  activities,  but may benefit
from such  activities  undertaken  by the  owners of the  working  interests  in
properties  burdened by the  Company's  non-operating  interests.  The Company's
operations are concentrated in a single industry segment.

             The  principal  executive  office of the Company is  maintained  at
Suite 200, Three Kingwood Place, Kingwood,  Texas 77339. The telephone number at
this office is (713) 358-8401. The Company has no regional offices.

     The Company has no employees.  On March 1, 1997, Enex and its  subsidiaries
employed 23 persons.

                                       I-1

Marketing

             The marketing of oil and gas produced by the Company is affected by
a number of factors which are beyond the Company's control,  the exact nature of
which cannot be accurately  predicted.  These  factors  include the quantity and
price of crude oil imports,  fluctuating  supply and demand,  pipeline and other
transportation facilities, the marketing of competitive fuels, state and federal
regulation  of oil  and  gas  production  and  distribution  and  other  matters
affecting the availability of a ready market. All of these factors are extremely
volatile.

             Coalinga  Corporation  accounted  for 100% of the  Company's  total
sales in 1996 and 1995.  Although the Company marketed a significant  portion of
its sales to the  above  noted  company,  such a  concentration  does not pose a
significant risk due to the commodity nature of the Company's products.

             The  Company's  operators  of the  properties  are  noted in Item 2
below.  Although a significant portion of the Company's properties were operated
by a limited number of operators, this concentration does not pose a significant
risk since the Company's rights are secured by joint operating agreements.

Environmental and Conservation Regulation

             State  regulatory  authorities  in the states in which the  Company
owns net profits  interests in producing  properties  are  empowered to make and
enforce  regulations to prevent waste of oil and gas and to protect  correlative
rights  and  opportunities  to  produce  oil  and  gas for  owners  of a  common
reservoir.  Each of such regulatory authorities also regulates the amount of oil
and gas  produced  by  assigning  allowable  rates of  production,  which may be
increased  or  decreased  in  accordance  with supply and  demand.  Requirements
regarding the  prevention  and clean-up of pollution  and similar  environmental
matters are also generally  applicable.  The costs, if any, that may be incurred
in this regard cannot be predicted.

             The  existence  of such  regulations  has had no  material  adverse
effects on the Company's  operations to date, and the cost of compliance has not
yet been material.  There are no material administrative or judicial proceedings
arising under such laws or regulations pending against the Company.  The Company
is unable to assess or predict the impact that compliance with environmental and
pollution  control  laws  and  regulations  may have on its  future  operations,
capital expenditures, earnings or competitive position.

Tax Laws

             The  operations  of the Company are affected by the federal  income
tax laws  contained  in the  Internal  Revenue  Code of 1986,  as  amended  (the
"Code").  In general,  the limited  partners of the Company will generate income
from the receipt of royalties and net profits  interests and will be entitled to
a depletion  deduction.  Net income,  if any, will generally be characterized as
portfolio  income  under  the Code and  will be  taxed  in the  same  manner  as
dividends and interest.


                                       I-2

<PAGE>



             Partnerships with interests that are "publicly traded" are taxed as
corporations unless at least 90% of their income is "qualifying income." Because
the  Company's  income will be qualifying  income for this purpose,  the Company
will not be taxed as a corporation under this rule.


Item 2.      Description of Property

             Presented   below  is  a   summary   of  the   Company's   property
acquisitions.

Dividends

          The  Company  made  cash  distributions  to  partners  of $1 per  $500
investment in 1995. The Company discontinued the payment of distributions in the
second quarter of 1995.  Future  distributions  are dependent upon,  among other
things,  an increase in the prices  received  for oil and gas.  The Company will
continue to recover its  reserves  and reduce  obligations  in 1997.  Based upon
current  projected  cash flows from its  property,  it does not appear  that the
Company  will  have   sufficient  net  cash  flow  after  debt  service  to  pay
distributions in the near future.

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 increased to $51,886 in 1996 from $42,536 in 1995.
This  represents an increase of $9,350 or 22%. Oil sales  increased by $5,517 or
22%. A 37%  increase in the average oil net sales price  increased  oil sales by
$8,341. This increase was partially offset by an 11% decrease in oil production.
Gas sales  increased  by $3,833 or 22%. A 22%  increase  in the  average gas net
sales price increased sales by $3,936.  This increase was partially  offset by a
1% decrease in gas  production.  The  increases in average oil and gas net sales
prices  correspond  with higher prices in the overall market for the sale of oil
and gas. The decrease in oil and gas  production  were  primarily due to natural
production declines.

            Depletion expense decreased to $16,115 in 1996 from $31,416 in 1995.
This  represents a decrease of $15,301 or 49%. The changes in production,  noted
above,  caused  depletion  expense to decrease by $1,588.  A 46% decrease in the
depletion rate reduced depletion expense by an additional $13,713.  The decrease
in the depletion  rate was due to the lower  property  basis  resulting from the
recognition of an impairment for $240,044 in the first quarter of 1996, as noted
below,  partially  offset by a  downward  revision  of the oil and gas  reserves
during December 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. Prior to this
pronouncement,  the Company  assessed  properties  on an aggregate  basis.  Upon
adoption of SFAS 121, the Company  began  assessing  properties on an individual
basis, wherein total capitalized costs may not exceed the property's fair market
value.  The fair market value of each property was  determined by H. J. Gruy and
Associates,  ("Gruy").  To determine the fair market value,  Gruy estimated each
property's oil and gas reserves, applied certain assumptions regarding price and
cost  escalations,  applied a 10% discount factor for time and certain  discount
factors for risk,  location,  type of ownership interest,  category of reserves,
operational  characteristics,  and other factors.  In the first quarter of 1996,
the Company recognized a non-cash  impairment  provision of $240,044 for certain
oil and gas  properties due to market  conditions  and reserve  revisions on the
Lake Decade  acquisition,  which  indicated  that the carrying  amounts were not
fully recoverable.

            General and  administrative  expenses  increased  to $13,790 in 1996
from $12,352 in 1995.  This  increase of $1,438 or 12% was  primarily due a $984
increase in direct costs incurred by the Company in 1996 coupled with more staff
time being required to manage the Company's  operations.  The increase in direct
expenses  was due to  higher  audit and tax  preparation  fees  incurred  by the
Company in 1996.

Capital Resources and Liquidity

            The Company's  cash flows from  operations is a result of the amount
of net proceeds  realized from the sale of oil and gas production.  Accordingly,
the changes in cash flows 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 net cash flows to the
Company's partners.


                                      II-2

            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. The Company plans to repay the amount owed to the general
partner over a seven year period.  Distributions decreased from 1995 to 1996 due
primarily to the repayment of debt in 1996. The Company discontinued the payment
of  distributions  in the  second  quarter  of 1995.  Future  distributions  are
dependent  upon among other  things,  the prices  received  for oil and gas. The
Company  will  continue to recover its reserves  and reduce its  obligations  in
1997.  The general  partner does not intend to  accelerate  the repayment of the
debt beyond the cash flow provided by operating  activities.  Based upon current
projected cash flows from its property, it does not appear that the Company will
have  sufficient  net cash flow after debt service to pay  distributions  in the
near future.

             subsidiary of Enex, and reimbursed Enex for  organization  expenses
             of approximately $55,000.

             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 proved reserves.  The acquisition costs of proved oil and
             gas  properties  are  capitalized  and  periodically  assessed  for
             impairments.

             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.  Prior to this  pronouncement,  the
             Company assessed properties on an aggregate basis. Upon adoption of
             SFAS 121, the Company began  assessing  properties on an individual
             basis,   wherein  total   capitalized  costs  may  not  exceed  the
             property's  fair  market  value.  The  fair  market  value  of each
             property was determined by H. J. Gruy and Associates,  ("Gruy"). To
             determine the fair market value, Gruy estimated each property's oil
             and gas reserves,  applied certain assumptions  regarding price and
             cost  escalations,  applied  a 10%  discount  factor  for  time and
             certain  discount  factors for risk,  location,  type of  ownership
             interest, category of reserves,  operational  characteristics,  and
             other factors. In the first quarter of 1996, the Company recognized
             a non-cash impairment provision of $240,044 for certain oil and gas
             properties due to market  conditions  and reserve  revisions on the
             Lake Decade acquisition,  which indicated that the carrying amounts
             were not fully recoverable.

             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
             contingent  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 seven 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.

6.           SIGNIFICANT PURCHASERS

             Coalinga  Corporation  accounted  for 100% of the  Company's  total

              On January 4, 1996, the SEC filed a complaint in the United States
District  Court for the District of Columbia  against Mr. Carl alleging that Mr.
Carl violated  Section 16(a) of the Securities  Exchange Act of 1934  ("Exchange
Act"), and Rule 16a-2 and 16a-3 (and former Rule 16a-1)  thereunder,  by failing
to timely file reports concerning  thirty-eight  securities  transactions in his
mother's brokerage  accounts involving shares of Health Images,  Inc. stock. The
SEC took the position that because Mr. Carl (1) provided substantial

                                      III-2

<PAGE>



financial  support to his mother,  (2) commingled  his mother's  assets with his
own, (3) provided a substantial portion of the funds used to purchase the shares
in question, and (4) received from his mother a substantial portion of the sales
proceeds, he, therefore, had a pecuniary interest in, and was a beneficial owner
of, the shares in question.

              In response to the SEC's  action,  Mr.  Carl  disgorged  to Health
Images,  Inc.  approximately  $92,400 in short-swing profits from the trading in
his mother's account,  plus interest thereon of approximately  $52,600.  The SEC
further  requested the court to impose a $10,000 civil penalty  against Mr. Carl
pursuant to Section 21(d)(3) of the Exchange Act.  Without  admitting or denying
the  allegations  in the  complaint,  Mr. Carl consented to the entry of a final
judgement  imposing the $10,000  penalty.  On January 12, 1996, a federal  judge
entered the final judgement in this matter, and Mr. Carl has since filed amended
reports on Forms 4 and 5 reflecting these transactions in his mother's accounts.

              In   relation  to  the  same   matter,   the  SEC  has  issued  an
administrative  Order  pursuant to Section 21C of the  Exchange  Act against Mr.
Carl,  finding  that he  violated  Section  16(a) and the rules  thereunder  and
requiring  him to cease and desist from  committing  or causing any violation or
future violation of those provisions.  Without admitting or denying  allegations
in the SEC's Order, Mr. Carl consented to the entry of the Order.
