                   CONDENSED NOTES TO FINANCIAL STATEMENTS
                                MARCH 31, 1998
                                  (Unaudited)


1.    ACCOUNTING POLICIES
      -------------------

      The balance sheet as of March 31, 1998,  statements of operations  for the
      three months ended March 31, 1998 and 1997,  and  statements of cash flows
      for the three months  ended March 31, 1998 and 1997 have been  prepared by
      Dyco Petroleum Corporation  ("Dyco"),  the General Partner of the Dyco Oil
      and Gas Program 1985-1 and 1985-2 Limited Partnerships (individually,  the
      "1985-1  Program"  or the  "1985-2  Program",  as the  case  may  be,  or,
      collectively, the "Programs"), without audit. In the opinion of management
      all  adjustments   (which  include  only  normal  recurring   adjustments)
      necessary  to present  fairly the  financial  position at March 31,  1998,
      results of operations  for the three months ended March 31, 1998 and 1997,
      and  changes in cash flows for the three  months  ended March 31, 1998 and
      1997 have been made.

      Information  and  footnote  disclosures  normally  included  in  financial
      statements  prepared in  accordance  with  generally  accepted  accounting
      principles  have been  condensed or omitted.  It is  suggested  that these
      financial  statements be read in conjunction with the financial statements
      and notes thereto included in the Programs' Annual Report on Form 10-K for
      the year ended December 31, 1997. The results of operations for the period
      ended March 31, 1998 are not  necessarily  indicative of the results to be
      expected for the full year.

      The  limited  partners'  net  income  or loss per unit is based  upon each
      $5,000 initial capital contribution.


      OIL AND GAS PROPERTIES
      ----------------------

      Oil and gas  operations  are  accounted  for using the full cost method of
      accounting.  All productive and  non-productive  costs associated with the
      acquisition,  exploration  and  development  of oil and gas  reserves  are
      capitalized.  The Programs'  calculation of depreciation,  depletion,  and
      amortization  includes  estimated  future  expenditures  to be incurred in
      developing  proved  reserves and estimated  dismantlement  and abandonment
      costs, net of estimated  salvage values. In the event the unamortized cost
      of oil and gas properties being amortized exceeds the full cost



                                       8
<PAGE>



      ceiling (as defined by the Securities and Exchange Commission), the excess
      is charged to expense in the period during which such excess occurs. Sales
      and  abandonments  of  properties  are  accounted  for as  adjustments  of
      capitalized costs with no gain or loss recognized, unless such adjustments
      would significantly  alter the relationship  between capitalized costs and
      proved oil and gas reserves.

      The provision for depreciation, depletion, and amortization of oil and gas
      properties is calculated by dividing the oil and gas sales dollars  during
      the  period by the  estimated  future  gross  income  from the oil and gas
      properties and applying the resulting  rate to the net remaining  costs of
      oil and gas properties that have been  capitalized,  plus estimated future
      development costs.


2.    TRANSACTIONS WITH RELATED PARTIES
      ---------------------------------

      Under the terms of each Program's partnership agreement,  Dyco is entitled
      to  receive a  reimbursement  for all  direct  expenses  and  general  and
      administrative, geological and engineering expenses it incurs on behalf of
      the  Program.  During the three  months  ended March 31, 1998 and 1997 the
      1985-1  Program  incurred  such  expenses  totaling  $18,520 and  $19,770,
      respectively,  of which  $10,710  was  paid  each  period  to Dyco and its
      affiliates.  During the three  months  ended  March 31,  1998 and 1997 the
      1985-2  Program  incurred  such  expenses  totaling  $18,316 and  $19,638,
      respectively,  of which  $10,068  was  paid  each  period  to Dyco and its
      affiliates.

      Affiliates of the Programs  operate  certain of the Programs'  properties.
      Their policy is to bill the Programs  for all  customary  charges and cost
      reimbursements associated with these activities.

      The  receivable  from the  General  Partner at March 31,  1998  represents
      proceeds due to the 1985-2 Program from the sale of oil and gas properties
      to third parties during the first quarter of 1998. Subsequent to March 31,
      1998, this receivable was collected by the 1985-2 Program.

ITEM 2.     MANAGEMENT'S  DISCUSSION  AND ANALYSIS OF FINANCIAL  CONDITION AND
            RESULTS OF OPERATIONS


USE OF FORWARD-LOOKING STATEMENTS AND ESTIMATES
-----------------------------------------------

      This Quarterly Report contains  certain  forward-looking  statements.  The
      words "anticipate",  "believe",  "expect",  "plan", "intend",  "estimate",
      "project", "could", "may" and similar expressions are intended to identify
      forward-looking  statements.  Such statements reflect management's current
      views  with  respect  to future  events and  financial  performance.  This
      Quarterly Report also includes certain information,  which is, or is based
      upon,  estimates  and  assumptions.  Such  estimates and  assumptions  are
      management's  efforts to accurately reflect the condition and operation of
      the Program.

      Use of  forward-looking  statements and estimates and assumptions  involve
      risks  and  uncertainties  which  include,  but are not  limited  to,  the
      volatility of oil and gas prices, the uncertainty of reserve  information,
      the operating risk associated  with oil and gas properties  (including the
      risk of personal injury,  death,  property  damage,  damage to the well or
      producing  reservoir,  environmental  contamination,  and other  operating
      risks), the prospect of changing tax and regulatory laws, the availability
      and capacity of  processing  and  transportation  facilities,  the general
      economic climate,  the supply and price of foreign imports of oil and gas,
      the level of consumer  product demand,  and the price and  availability of
      alternative  fuels.  Should  one or more of these  risks or  uncertainties
      occur or should  estimates  or  underlying  assumptions  prove  incorrect,
      actual  conditions or results may vary materially and adversely from those
      stated, anticipated, believed, estimated, and otherwise indicated.


LIQUIDITY AND CAPITAL RESOURCES
-------------------------------

      Net  proceeds  from the  Programs'  operations  less  necessary  operating
      capital  are  distributed  to  investors  on a  quarterly  basis.  The net
      proceeds from production are not reinvested in productive  assets,  except
      to the extent  that  producing  wells are  improved  or where  methods are
      employed to permit more efficient recovery of the Programs' reserves which
      would result in a positive economic impact.







                                       10
<PAGE>




      The Programs'  available capital from  subscriptions has been spent on oil
      and gas drilling  activities.  There should be no further material capital
      resource commitments in the future. The Programs have no debt commitments.
      Cash for  operational  purposes  will be  provided  by current oil and gas
      production.


RESULTS OF OPERATIONS
---------------------

      GENERAL DISCUSSION

      The following  general  discussion  should be read in conjunction with the
      analysis  of results of  operations  provided  below.  The most  important
      variable  affecting the Programs'  revenues is the prices received for the
      sale  of  oil  and  gas.  Predicting  future  prices  is  very  difficult.
      Substantially  all of the  Programs'  gas  reserves  are being sold in the
      "spot market".  Prices on the spot market are subject to wide seasonal and
      regional pricing  fluctuations due to the highly competitive nature of the
      spot market. In addition,  such spot market sales are generally short-term
      in nature and are dependent upon the obtaining of transportation  services
      provided by pipelines.  Management is unable to predict whether future oil
      and gas prices will (i) stabilize, (ii) increase, or (iii) decrease.

      Oil and gas sales                           $95,021          $149,957
      Oil and gas production expenses             $26,317          $ 17,072
      Barrels produced                                 74                 -

      Average price/Mcf                           $  2.14          $   2.12

      As shown in the table  above,  total oil and gas sales  decreased  $54,936
      (36.6%) for the three months ended March 31, 1998 as compared to the three
      months ended March 31, 1997. Of this decrease,  approximately  $57,000 was
      related  to a  decrease  in  volumes  of gas  sold.  Volumes  of oil  sold
      increased 74 barrels,  while volumes of gas sold decreased  26,742 Mcf for
      the three  months  ended March 31,  1998 as  compared to the three  months
      ended  March 31,  1997.  The  decrease  in  volumes  of gas sold  resulted
      primarily from



                                       11
<PAGE>



      positive prior period volume  adjustments made by the purchaser on several
      wells during the three  months  ended March 31,  1997.  Average gas prices
      remained  relatively  constant at $2.14 per Mcf for the three months ended
      March 31, 1998  compared to $2.12 per Mcf for the three months ended March
      31, 1997.

      Oil and gas production  expenses  (including lease operating  expenses and
      production  taxes)  increased  $9,245  (54.2%) for the three  months ended
      March 31, 1998 as compared to the three months ended March 31, 1997.  This
      increase  resulted  primarily from credits  received from the operators on
      two wells  during the three  months  ended March 31, 1997 for prior period
      operating  expenses,  partially  offset by a decrease in production  taxes
      associated  with the decrease in oil and gas sales  discussed  above. As a
      percentage of oil and gas sales, these expenses increased to 27.7% for the
      three  months  ended March 31, 1998 from 11.4% for the three  months ended
      March 31, 1997. This  percentage  increase was primarily due to the dollar
      increase in production expenses discussed above.

      Depreciation,  depletion,  and  amortization  of oil  and  gas  properties
      decreased  $13,236  (61.3%) for the three  months  ended March 31, 1998 as
      compared to the three months ended March 31, 1997. This decrease  resulted
      primarily  from (i)  decreases  in  volumes  of gas sold  during the three
      months  ended March 31, 1998 as compared to the three  months  ended March
      31,  1997  and (ii)  significant  upward  revisions  in the  estimates  of
      remaining  oil and gas reserves at December 31, 1997.  As a percentage  of
      oil and gas sales,  this  expense  decreased  to 8.8% for the three months
      ended March 31, 1998 from 14.4% for the three months ended March 31, 1997.
      This  percentage  decrease  was  primarily  due to the dollar  decrease in
      depreciation, depletion, and amortization discussed above.

      General and administrative  expenses decreased $1,250 (6.3%) for the three
      months  ended March 31, 1998 as compared to the three  months  ended March
      31, 1997. As a percentage of oil and gas sales,  these expenses  increased
      to 19.5% for the three  months  ended  March 31,  1998 from  13.2% for the
      three months ended March 31, 1997. This percentage  increase was primarily
      due to the decrease in oil and gas sales discussed above.

                                              Three Months Ended March 31,
                                              ----------------------------
                                                   1998             1997
                                                  -------          -------
      Oil and gas sales                           $35,984          $39,596
      Oil and gas production expenses             $19,719          $ 3,428
      Barrels produced                                685              141
      Mcf produced                                 13,063           17,200
      Average price/Bbl                           $ 13.99          $ 19.57
      Average price/Mcf                           $  2.02          $  2.14

      As shown in the table  above,  total oil and gas  sales  decreased  $3,612
      (9.1%) for the three  months ended March 31, 1998 as compared to the three
      months ended March 31, 1997. Of this  decrease,  approximately  $9,000 was
      related to a decrease in volumes of gas sold and approximately  $4,000 and
      $2,000,  respectively,  were related to decreases in the average prices of
      oil and gas sold,  which amounts were  partially  offset by an increase of
      approximately  $11,000  related  to an  increase  in  volumes of oil sold.
      Volumes  of oil sold  increased  544  barrels,  while  volumes of gas sold
      decreased  4,137 Mcf for the three months ended March 31, 1998 as compared
      to the three months  ended March 31, 1997.  The increase in volumes of oil
      sold resulted  primarily  from a negative  prior period volume  adjustment
      made by the  purchaser on one well during the three months ended March 31,
      1997.  The  decrease in volumes of gas sold  resulted  primarily  from (i)
      positive prior period volume  adjustments made by the purchaser on several
      wells during the three months ended March 31, 1997 and (ii) the receipt in
      1998  of a  reduced  percentage  of  sales  due  to the  1985-2  Program's
      overproduced  position on one significant well. Average oil and gas prices
      decreased  to $13.99 per barrel and $2.02 per Mcf,  respectively,  for the
      three  months  ended  March 31,  1998 from $19.57 per barrel and $2.14 per
      Mcf, respectively, for the three months ended March 31, 1997.

      Oil and gas production  expenses  (including lease operating  expenses and
      production  taxes)  increased  $16,291 (475.2%) for the three months ended
      March 31, 1998 as compared to the three months ended March 31, 1997.  This
      increase resulted primarily from (i) credits received from the operator of
      one well during the three  months  ended  March 31, 1997 for prior  period
      operating  expenses and (ii) an increase in general repair and maintenance
      expenses incurred on one well during the three months ended March 31, 1998
      as compared to the three months ended March 31, 1997.  As a percentage  of
      oil and gas sales, these expenses increased to 54.8% for the

      three  months  ended March 31, 1998 from 8.7% for the three  months  ended
      March 31, 1997. This  percentage  increase was primarily due to the dollar
      increase in production expenses discussed above.

      Depreciation,  depletion,  and  amortization  of oil  and  gas  properties
      decreased  $750  (24.4%)  for the three  months  ended  March 31,  1998 as
      compared to the three months ended March 31, 1997. This decrease  resulted
      primarily  from (i) the  decrease  in volumes of gas sold during the three
      months  ended March 31, 1998 as compared to the three  months  ended March
      31, 1997 and (ii)  upward  revisions  in the  estimate  of  remaining  gas
      reserves at December 31, 1997. As a percentage of oil and gas sales,  this
      expense  remained  relatively  constant at 6.5% for the three months ended
      March 31, 1998 as compared  to 7.8% for the three  months  ended March 31,
      1997.

      General and administrative  expenses decreased $1,332 (6.7%) for the three
      months  ended March 31, 1998 as compared to the three  months  ended March
      31, 1997. As a percentage of oil and gas sales,  these  expenses  remained
      relatively  constant at 50.9% for the three months ended March 31, 1998 as
      compared to 49.6% for the three months ended March 31, 1997.
