                        POLARIS AIRCRAFT INCOME FUND II,
                        A California Limited Partnership

                     NOTES TO CONDENSED FINANCIAL STATEMENTS
                                   (Unaudited)


Note 1.    Organization and the Partnership

Polaris Aircraft Income Fund II, A California  Limited  Partnership  (PAIF-II or
the  Partnership),  was formed on June 27, 1984 for the purpose of acquiring and
leasing  aircraft.  The Partnership  will terminate no later than December 2010.
Upon  organization,  both the General  Partner and the initial  Limited  Partner
contributed  $500.  The  Partnership  recognized no profits or losses during the
periods ended  December 31, 1984 and 1985.  The offering of Limited  Partnership
units  terminated on December 31, 1986, at which time the  Partnership  had sold
499,997 units of $500, representing $249,998,500.  All partners were admitted to
the  Partnership  on or before  December 1, 1986.  During January 1998, 24 units
were redeemed by the  Partnership  in accordance  with section 18 of the Limited
Partnership Agreement.  During the six months ended June 30, 2004, 27 units were
abandoned.  At June 30,  2004,  there were  499,730  units  outstanding,  net of
redemption.

As of June 30,  2004,  the  Partnership  owned  six  aircraft,  which  are being
marketed for sale.  Upon  completion  of such sales,  the  Partnership  plans to
liquidate all its assets in an orderly manner,  make a final  distribution,  and
terminate  the  Partnership  thereafter;  however,  it is  uncertain  when  this
liquidation  will occur.  The General Partner is actively seeking buyers for the
aircraft;  however the actual  timing for  completing  such sales and the prices
obtained will depend upon a number of factors outside the control of the General
Partner,  including  market  conditions.  Thus,  there can be no assurance as to
either the timing of such sales or whether  such sales may be completed on terms
deemed  favorable to the  Partnership.  However,  the General Partner intends to
seek to complete such sales during  calendar  year 2004. On April 14, 2004,  the
Partnership  entered into a Letter of Intent to sell its six remaining  aircraft
to an unaffiliated  buyer, and on August 6, 2004 executed a definitive  Aircraft
Sale and Purchase  Agreement for a total selling price of $820,000.  The General
Partner expects to complete the sale during the third quarter of 2004.

Polaris Investment  Management  Corporation  (PIMC), the sole General Partner of
the Partnership,  supervises the day-to-day operations of the Partnership.  PIMC
is a wholly-owned  subsidiary of Polaris  Aircraft Leasing  Corporation  (PALC).
Polaris  Holding Company (PHC) is the parent company of PALC.  General  Electric
Capital Corporation (GE Capital), an affiliate of General Electric Company, owns
100% of PHC's  outstanding  common  stock.  PIMC  has  entered  into a  services
agreement  dated as of July 1,  1994 with GE  Capital  Aviation  Services,  Inc.
(GECAS).  Amounts paid and allocations to related parties are described in Notes
4 and 5.


Note 2.    Reclassification

Certain 2003 amounts have been reclassified to conform to the 2004 presentation.
These  reclassifications  had no impact on  previously  reported  net  income or
partners' capital.

                                       7



Note 3.    Accounting Principles and Policies

In the opinion of  management,  the  condensed  financial  statements  presented
herein  include all  adjustments,  consisting  only of normal  recurring  items,
necessary to summarize fairly the Partnership's  financial  position and results
of operations.  The financial  statements  have been prepared in accordance with
the  instructions  of the  Quarterly  Report  to  the  Securities  and  Exchange
Commission (SEC) Form 10-Q. The condensed balance sheet at December 31, 2003 has
been derived  from the audited  financial  statements  at that date but does not
include all of the  information  and note  disclosures  required  by  accounting
principles  generally  accepted in the United States  (GAAP).  These  statements
should be read in  conjunction  with the financial  statements and notes thereto
for  the  years  ended  December  31,  2003,  2002,  and  2001  included  in the
Partnership's 2003 Annual Report to the SEC on Form 10-K.


Note 4.    Related Parties

                                            ========              ========


Note 5.    Partners' Capital

The Agreement  stipulates  different  methods by which revenue,  income and loss
from  operations and gain or loss on the sale of aircraft are to be allocated to
the General Partner and the Limited  Partners.  Such  allocations are made using
income or loss calculated under GAAP for book purposes, which varies from income
or loss calculated for tax purposes.

Cash  available  for  distributions,  including  the  proceeds  from the sale of
aircraft,  is  distributed  10% to the  General  Partner  and 90% to the Limited
Partners.

The different methods of allocating items of income, loss and cash available for
distribution  combined with the calculation of items of income and loss for book
and  tax  purposes  result  in  book  basis  capital   accounts  that  may  vary
significantly  from tax basis capital  accounts.  The ultimate  liquidation  and
distribution  of remaining cash will be based on the tax basis capital  accounts
following liquidation, in accordance with the Agreement.

                                       8




Note 6.    Aircraft and Depreciation

The  Partnership  periodically  reviewed  the  estimated  realizability  of  the
residual values at the projected end of each  aircraft's  economic life. For any
downward  adjustment  in estimated  residual  value or decrease in the projected
remaining economic life, the depreciation  expense over the projected  remaining
economic life of the aircraft was increased.

Aircraft on lease were carried at cost unless deemed impaired, in which case the
asset was recorded at fair value. Aircraft on lease were deemed impaired, if the
projected  net cash flow for each aircraft  (projected  rental  revenue,  net of
management  fees, less projected  maintenance  costs, if any, plus the estimated
residual value) was less than the carrying value of the aircraft.  An impairment
loss was recognized  equal to the  difference  between the net carrying value of
the asset and its fair value.

Aircraft  held for sale are carried at the lower of cost or fair value less cost
to sell. During the six months ended June 30, 2004, the Partnership recognized a
write-up  of  $175,000 in the  carrying  value of aircraft  held for sale due to
changes in  estimated  fair  market  values  based on the  selling  price of the
Partnership's  remaining  aircraft  negotiated in a Letter of Intent dated April
14, 2004. The adjustment to increase the net carrying value does not result in a
net carrying  value in excess of the  original net carrying  value of the assets
when they were initially  designated as held for sale.  Management  believes the
assumptions  related to the fair value of  impaired  assets  represent  the best
estimates based on reasonable and supportable assumptions and projections.


Note 7.    Sale of Aircraft

On February 9, 2004, the General Partner, on behalf of the Partnership sold four
DC-9-30 aircraft for $450,000 in cash. The Partnership  recognized a gain on the
sale of $1,000.

report.

Business Overview

At June 30, 2004,  Polaris  Aircraft Income Fund II (PAIF-II or the Partnership)
owned a portfolio of six used McDonnell Douglas DC-9-30  commercial jet aircraft
(DC-9-30) out of its original  portfolio of 30 aircraft.  These DC-9-30 aircraft
were being  stored in New Mexico and were being  marketed  for sale.  During the
three months ended March 31, 2004, the Partnership sold four DC-9-30 aircraft to
Newjet Corporation on February 9, 2004 for total cash proceeds of $450,000.  The
Partnership plans to liquidate all its assets in an orderly manner, make a final
distribution, and terminate the Partnership thereafter; however, it is uncertain
when this liquidation will occur. The General Partner is actively seeking buyers
for the aircraft;  however the actual timing for  completing  such sales and the
prices  obtained will depend upon a number of factors outside the control of the
General Partner, including market conditions. Thus, there can be no assurance as
to either the timing of such sales or  whether  such sales may be  completed  on
terms deemed favorable to the Partnership.  However, the General Partner intends
to seek to complete such sales during calendar year 2004. On April 14, 2004, the
Partnership  entered into a Letter of Intent to sell its six remaining  aircraft
to an unaffiliated  buyer, and on August 6, 2004 executed a definitive  Aircraft
Sale and Purchase  Agreement for a total selling price of $820,000.  The General
Partner expects to complete the sale during the third quarter of 2004.

Partnership Operations

The Partnership recorded a net loss of $49,539, or $0.10 per Limited Partnership
Unit,  for the three  months  ended  June 30,  2004,  compared  to net income of

                                       10


$236,223, or $0.47 per Limited Partnership Unit, for the three months ended June
30, 2003. The  Partnership  recorded net a loss of $7,400,  or $0.19 per Limited
Partnership Unit, for the six months ended June 30, 2004, compared to net income
of $505,711, which resulted in a net loss of $0.20 per Limited Partnership Unit,
for the six  months  ended  June  30,  2003.  Variances  in net  income  may not
correspond  to variances in net income per Limited  Partnership  Unit due to the
allocation  of  components  of income and loss in  accordance  with the  Limited
Partnership Agreement.

The decrease in net income  during the three and six months ended June 30, 2004,
as  compared  to the same  periods in 2003,  is  primarily  due to an absence of
rental  income,  partially  offset by an absence  of  depreciation  expense  and
management fees to the General Partner, as discussed below.

The absence of rental  income  from  operating  leases  during the three and six
months ended June 30, 2004,  as compared to $657,358 and  $1,619,453 in the same
periods in 2003, is due to all lease terms having expired during 2003.

Interest  income  decreased  slightly during the three and six months ended June
30,  2004,  as  compared  to the same  periods in 2003,  primarily  due to lower
interest rates and lower average cash balances.

The  recognized  gain on sale of aircraft  during the six months  ended June 30,
2004 of  $1,000  was due to the sale of four of the  Partnership's  aircraft  on
February 9, 2004 for  $450,000.  There were no aircraft  sales  during the three
months ended June 30, 2004 and the three and six months ended June 30, 2003.

There were no revenues  from  payments of lessee  return  condition  settlements
during the three and six months ended June 30, 2004,  as compared to $90,630 and
$120,745,  respectively,  for the same  periods  in 2003,  due to all  remaining
aircraft having been returned upon lease expiration  during 2003. There were two
aircraft  returned  during the three  months  ended June 30, 2003 and a total of
three  aircraft  returned  during the six  months  ended  June 20,  2003,  which
required a lessee return condition settlement to be paid.

Lessee  settlement  income  increased  slightly  during the three and six months
ended June 30, 2004,  as compared to the same periods in 2003,  due to a payment
received  during the three and six months  ended June 30,  2004 in the amount of
$75,024,  as compared to $69,346  received during the three and six months ended
June 30, 2003. The payment  received  during the 2004 and 2003 periods  resulted
from  distributions  by TWA's  bankrupt  estate  representing  a portion  of the
$422,989  administrative rent claims initially filed by the Partnership pursuant
to the bankruptcy.

Aircraft  held for sale are carried at the lower of cost or fair value less cost
to sell.  During the six months ended June 30, 2004, the Partnership  recognized
income of $175,000,  or $0.35 per Limited  Partnership  Unit, on the write-up of
the carrying  value of five of its aircraft,  which  previously had been reduced
through  additional  depreciation  expense  as the  result  of past  reviews  of
estimated market values. The current estimated fair market value of the aircraft
held  for sale  was  based on the  total  purchase  price  of  $820,000  for the
Partnership's  six  DC-9-30's in a Letter of Intent  dated April 14,  2004.  The
carrying value of one of the Partnership's aircraft was not adjusted because its
cost basis  determined at lease  expiration was less than the current  estimated
fair market value. No further adjustments were made to the carrying value of the
aircraft  during the three months ended June 30, 2004 because the Partnership is
expected  to receive  the  selling  price of  $820,000  when the sale of the six
aircraft occurs as anticipated  during the third quarter of 2004. No adjustments
to the market value of aircraft held for sale were made during the three and six
months ended June 30, 2003.

                                       11



The absence of  depreciation  expense and management fees to the General Partner
during the three and six  months  ended June 30 2004,  as  compared  to the same
periods in 2003, was due to all lease terms having expired during 2003.

Operating  expenses  decreased  during the three and six  months  ended June 30,
2004, as compared to the same periods in 2003,  primarily due to maintenance and
storage related costs associated with the aircraft while they are being held for
sale.  During the six months  ended June 30,  2004,  ten  aircraft  were held in
storage until  February 9, 2004 when four were sold and six remained in storage,
as  compared  to the same  period  in 2003,  when  seven  aircraft  were kept in
storage.

Administration and other expenses increased slightly during the three months and
six  months  ended  June 30,  2004,  as  compared  to the same  periods in 2003,
primarily due to higher legal fees related to various SEC and investor reporting
matters.

Liquidity and Cash Distributions

Liquidity - No further rent  payments  were due during the six months ended June
30, 2004 since all lease terms expired during 2003. The Partnership received all
payments due from its sole lessee,  TWA Airlines LLC, for the aircraft remaining
on lease during the six months ended June 30, 2003.

PIMC, the General Partner,  has determined that cash reserves be maintained as a
prudent  measure to ensure that the  Partnership has available funds for winding
up the affairs of the Partnership and for other  contingencies.  The Partnership
plans  to  liquidate  all  its  assets  in  an  orderly  manner,  make  a  final
distribution, and terminate the Partnership thereafter; however, it is uncertain
when this liquidation will occur. The General Partner is actively seeking buyers
for the aircraft;  however the actual timing for  completing  such sales and the
prices  obtained will depend upon a number of factors outside the control of the
General Partner, including market conditions. Thus, there can be no assurance as
to either the timing of such sales or  whether  such sales may be  completed  on
terms deemed favorable to the Partnership.  However, the General Partner intends
to seek to complete  such sales  during  calendar  year 2004 and,  as  discussed
above,  on April 14, 2004,  the  Partnership  entered into a Letter of Intent to
sell its six remaining aircraft to an unaffiliated  buyer, and on August 6, 2004
executed a definitive  Aircraft Sale and Purchase  Agreement for a total selling
price of $820,000.  The Partnership's cash reserves will be monitored and may be
revised  from  time to time as  further  information  becomes  available  in the
future.

Cash  Distributions  - Cash  distributions  to Limited  Partners  during the six
months  ended  June 30,  2004 and  2003  were  $874,575,  or $1.75  per  Limited
Partnership Unit, and $6,248,876, or $12.50 per Unit, respectively.  The General
Partner has determined  that it is in the best  interests of the  Partnership to
suspend any further cash distributions until the Partnership is in a position to
dissolve, wind up and terminate,  and make a final distribution of its remaining
cash.  In  reaching  this  conclusion,   the  General  Partner   considered  the
anticipated  costs of storing  and  insuring  the  aircraft  pending  sale,  the
anticipated  costs of  marketing  and  preparing  the  aircraft  for  sale,  the
anticipated costs of winding up the Partnership's  business,  the uncertainty as
to the period of time required to sell the aircraft and wind up the Partnership,
the uncertainty as to the terms on which the Partnership's  aircraft may be sold
and the  desirability  of  maintaining  a  prudent  level of cash  reserves  for
Partnership needs and contingencies.

The  Partnership  does not have any material off balance  sheet  commitments  or
obligations.

                                       12


Item 4.    Controls and Procedures

(a) Evaluation of disclosure controls and procedures

PIMC management reviewed the Partnership's  internal controls and procedures and
the  effectiveness  of these  controls.  As of June 30, 2004,  PIMC  management,
including its Chief Executive Officer and Chief Financial  Officer,  carried out
an  evaluation  of  the  effectiveness  of  the  design  and  operation  of  the
Partnership's disclosure controls and procedures pursuant to Rules 13a-14(c) and
15d-14(c) of the Securities  Exchange Act of 1934.  Based upon that  evaluation,
the Chief  Executive  Officer and Chief  Financial  Officer  concluded  that the
Partnership's  disclosure  controls  and  procedures  are  effective  in  timely
alerting them to material information relating to the Partnership required to be
included in its periodic SEC filings.

(b) Change to internal controls

There  was no change  in the  Partnership's  internal  controls  over  financial
reporting  or in other  factors  during  the  Partnership's  last  quarter  that
materially  affected,  or  are  reasonably  likely  to  materially  affect,  the
Partnership's  internal  controls  over  financial  reporting.   There  were  no
significant  deficiencies  or material  weaknesses,  and therefore no corrective
actions taken.
