1.    Basis of Presentation

      The consolidated  financial statements of ICON Cash Flow Partners L.P. Six
(the  "Partnership") have been prepared pursuant to the rules and regulations of
the  Securities  and  Exchange  Commission  (the  "SEC")  and, in the opinion of
management,  include  all  adjustments  (consisting  only  of  normal  recurring
accruals)  necessary  for a fair  statement  of income  for each  period  shown.
Certain information and footnote  disclosures  normally included in consolidated
financial  statements  prepared in accordance with generally accepted accounting
principles  have  been  condensed  or  omitted  pursuant  to such SEC  rules and
regulations.  Management believes that the disclosures made are adequate to make
the information  represented not misleading.  The results for the interim period
are  not  necessarily  indicative  of the  results  for  the  full  year.  These
consolidated  financial  statements  should  be read  in  conjunction  with  the
consolidated  financial  statements and notes included in the Partnership's 1998
Annual Report on Form 10-K.

2.    Redemption of Limited Partnership Units

      The General  Partner  consented to the  Partnership  redeeming 985 and 465
limited  partnership  units during the nine months ended  September 30, 1999 and
1998, respectively. The redemption amount was calculated following the specified
redemption formula in the Partnership  agreement.  Redeemed units have no voting
rights and do not share in distributions.  The Partnership  agreement limits the
number of units which can be redeemed in any one year and redeemed units may not
be reissued. Redeemed limited partnership units are accounted for as a deduction
from partners' equity.

3.    Net Investment in Leveraged Lease

      In September 1996 the Partnership acquired,  subject to a leveraged lease,
the beneficial  interest in an aircraft.  In December 1998 the Partnership  sold
the beneficial interest to Airbus Industrie.  The proceeds from the sale totaled
$20,834,705 and were used to pay off the debt and a third party under a residual
sharing  agreement.  The remaining proceeds were retained by the Partnership and
the  Partnership  recognized  an  $884,876  gain on the  sale of the  beneficial
interest.

4.    Related Party Transactions

      Fees paid or  accrued by the  Partnership  to the  General  Partner or its
affiliates for the nine months ended September 30, 1999 and 1998 are as follows:

             Notes to Consolidated Financial Statements (continued)

      The Partnership  has  investments in five joint ventures with  affiliates.
(See Note 5 for additional information relating to the joint ventures.)

5.    Investments in Joint Ventures

      The Partnership has investments in five joint ventures with affiliates for
the purpose of acquiring and managing various assets.

     AIC Trust

     In July 1999 the Partnership,  ICON Income Fund Eight A L.P. ("Fund Eight")
and ICON Cash Flow Partners L. P. Seven ("L. P. Seven")  formed a joint venture,
("AIC Trust"), for the purpose of managing a portfolio of lease assets.  Profit,
losses,  excess  cash  and  disposition  proceeds  are  allocated  based  on the
Partnership's  interest  in the  venture.  The  Partnership  has  acquired  a 0%
interest in the venture during the quarter ending September 30, 1999.

     ICON Boardman Funding L.L.C.

     In  December  1998 the  Partnership  and three  affiliates,  ICON Cash Flow
Partners,  L. P., Series C ("Series  C"),  ICON Cash Flow  Partners  L.P.  Seven
("L.P.  Seven")  and ICON  Income  Fund Eight A L.P.  ("Eight  A")  formed  ICON
Boardman  Funding L.L.C.  ("ICON BF"), for the purpose of acquiring a lease with
Portland  General  Electric.  The purchase  price totaled  $27,421,810,  and was
funded  with cash and  non-recourse  debt  assumed in the  purchase  price.  The
Partnership, Series C, L.P. Seven and Eight A received a .5%, .5%, .5% and 98.5%
interest,  respectively,  in ICON BF. The Partnership's  original investment was
recorded at cost of $56,960 and is adjusted by its share of earnings, losses and
distributions  thereafter.  Simultaneously  with the acquisition of the Portland
General Electric lease by ICON BF, a portion of the rent receivable in excess of
the senior  debt  payments  was  acquired  by the  Partnership  from ICON BF for
$3,801,108.  On March 30,  1999,  ICON BF  exercised  its right to  acquire  the
Partnership's  investment  in a portion of the rent  receivable in excess of the
senior debt payments for $3,097,637 and  simultaneously  financed,  with a third
party,  all of the rent receivable in excess of the senior debt payments.  There
was no gain or loss to the  Partnership  on this  transaction.  ICON BF received
$7,643,867  from the  financing.  The proceeds  from the  financing,  net of the
purchase of the  Partnership's  investment,  were  distributed to the members of
ICON BF in accordance with their ownership interests.

      ICON Receivables 1997-B L.L.C.

      In August 1997 the Partnership,  ICON Cash Flow Partners,  L. P., Series E
("Series E") and L.P. Seven formed ICON Receivables 1997-B L.L.C.  ("1997-B"), a
special  purpose entity for the purpose of originating  leases and  securitizing
its portfolio.  The  Partnership,  Series E and L.P. Seven  contributed cash and
received an 8.33%,  75.00% and 16.67%  interest,  respectively,  in 1997-B.  The
Partnership's  cash  contributions  amounted to $250,000 in 1997 and $163,978 in
1998. In order to fund the  acquisition of leases,  1997-B  obtained a warehouse
borrowing facility from a lender (the "1997-B Warehouse  Facility").  In October
1998,  1997-B completed an equipment  securitization.  The net proceeds from the
securitization  of these  assets  were  used to  pay-off  the  remaining  1997-B
Warehouse Facility balance and remaining proceeds were distributed to the 1997-B
members in accordance with their membership interests.  The Partnership accounts
for its  investment  in  1997-B  under the  equity  method  of  accounting.  The
Partnership's  original  investment  was recorded at cost and is adjusted by its
share of earnings, losses, contribution and distributions thereafter.

("Series  D"), and L.P.  Seven,  contributed  and assigned  equipment  lease and
finance receivables and residuals to ICON Receivables 1997-A L.L.C.  ("1997-A"),
a special purpose entity created for the purpose of originating leases, managing

equipment  lease  and  finance   receivables   and  residuals  to  1997-A.   The
Partnership,  Series D, Series E and L.P. Seven received a 31.03%, 17.81% 31.19%

losses, contributions and distributions thereafter.

Item 2. General  Partner's  Discussion  and Analysis of Financial  Condition and
Results of Operations

      The  Partnership's  portfolio  consisted of a net  investment in operating
leases, finance leases, investments in unconsolidated joint ventures, financings
and  leveraged  leases  of 47%,  47%,  5%,  1% and 0% of  total  investments  at
September  30,  1999,  respectively,  and  36%,  52%,  5%,  3% and  4% of  total
investments at September 30, 1998, respectively.

Results of Operations for the Three Months Ended September 30, 1999 and 1998

     For the three months ended  September 30, 1999 and 1998 the Partnership did
not enter into any new leases or financing agreements.

      Revenues  for the three months ended  September  30, 1999 were  $1,105,540
representing  a decrease of $154,853 or 12% from 1998.  The decrease in revenues
was due to a decrease in finance income of $105,607 or 20%, a decrease in income
from leveraged lease, net of $67,103 or 100%, a decrease in net gain on sales of
equipment  of  $64,428  or 73% and a decrease  in  interest  income and other of
$9,203 or 23%. These  decreases were partially  offset by income from investment
in unconsolidated joint ventures of $25,184 for the three months ended September
30, 1999 compared to the a loss from investment in unconsolidated joint ventures
of $66,304 for the three  months  ended  September  30,  1998.  The  decrease in
finance income resulted from a decrease in the average size of the finance lease
portfolio from 1998 to 1999. The decrease in income from leveraged  leases was a
result of the Partnership's 1998 termination of its lease with Airbus Industrie.
The decrease in net gain on sales of equipment  resulted  from a decrease in the
number of leases  maturing and a decrease in the amount of underlying  equipment
being  sold or  remarketed  for which  proceeds  received  were in excess of the
remaining carrying value. The decrease in interest income and other was due to a
decrease in late charge income.  For the three months ended  September 30, 1999,
the Partnership did not record any loss provision for 1997-A and the Partnership
earned  income  from  investments  in   unconsolidated   joint  ventures.   ICON
Receivables 1997-A L.L.C.  ("1997-A")  recorded a loss provision of $600,000 for
the three months ended September 30, 1998 resulting in a loss to the Partnership
from investments in unconsolidated joint ventures for that period.

     Expenses  for the three  months  ended  September  30,  1999 were  $865,867
representing  a decrease of $353,050 or 29% from 1998.  The decrease in expenses
was a result of a decrease in interest expense of $163,366 or 30%, a decrease in
management fees of $100,658 or 42%, a decrease in amortization of initial direct
costs of $99,286 or 72%, a decrease in administrative  expense reimbursements of
$45,971 or 38%, and a decrease in depreciation  expense of $19,189 or 11%. These
decreases  were  partially  offset by an increase in general and  administrative
expense of $29,936 or 56%.  The reversal in the  provision  for bad debt reduced
expenses  by $47,004 in 1998;  the  provison  for bad debt did not change in the
current  quarter.  The decrease in interest expense was due to a decrease in the
average debt  outstanding  from 1998 to 1999. The decreases in management  fees,
amortization of initial direct costs,  administrative expense reimbursements and
depreciation  were a result of a decrease  in the  average  size of the  finance
lease  portfolio  from 1998 to 1999. As a result of an analysis of  delinquency,
assessment  of overall  risk and a review of  historical  loss  experience,  the
Partnership  recorded a  reversal  of the  provision  for bad debt for the three
months ended  September  30, 1998 and recorded no provision for the three months
ended September 30, 1999. The increase in general and administrative expense was
due to an increase in professional fees.

      Net income for the three  months  ended  September  30,  1999 and 1998 was
$239,673 and $41,476,  respectively. The net income per weighted average limited
partnership unit outstanding was $.63 and .11 for 1999 and 1998, respectively.

Results of Operations for the Nine Months Ended September 30, 1999 and 1998

      For the nine months ended September 30, 1999 the Partnership did not enter
into any new leases or financing agreements. For the nine months ended September
30,  1998,  the  Partnership  leased or financed  additional  equipment  with an
initial cost of $2,822,604 to 4 lessees.

      Revenues for the nine months  ended  September  30, 1999 were  $3,997,578,
representing a decrease of $318,224 or 7%. The decrease in revenues was due to a
decrease in income from leveraged  lease, net of $181,275 or 100%, a decrease in
interest  income and other of $114,660  or 73%, a decrease in finance  income of
$101,471 or 6% and a decrease in income from investment in unconsolidated  joint
ventures of $73,026 or 28%. These decrease were partially  offset by an increase
in net gain on sales of  equipment  of $128,194 or 59%.  The  decrease in income
from leveraged leases was a result of the Partnership's  1998 termination of its
lease with Airbus  Industrie.  The  decrease  in  interest  income and other was
primarily  due to a decrease in interest  received  due to a lower  average cash
balance  from 1998 to 1999.  The  decrease  in finance  income  resulted  from a
decrease in the average size of the finance lease  portfolio  from 1998 to 1999.
The increase in net gain on sales of equipment  resulted from an increase in the
number of leases maturing and an increase in the amount of underlying  equipment
being sold for which proceeds received were in excess of the remaining  carrying
value.  Based on an analysis of  delinquency,  assessment  of overall risk and a
review of historical loss experience ICON Receivables 1997-B L.L.C.  ("(1997-B")
recorded a loss  provision of $900,000 for the nine months ended  September  30,
1999 compared to a loss  provision  recorded by ICON  Receivables  1997-A L.L.C.
("1997-A") of $600,000 for the nine months ended  September 30, 1998,  resulting
in a decrease for the  Partnership in income from  investment in  unconsolidated
joint ventures from 1998 to 1999.

      Expenses  for the nine months  ended  September  30, 1999 were  $2,889,323
representing  a decrease of  $1,153,585 or 29%. The decrease in expenses was due
to a decrease in interest expense of $436,537 or 26%, a decrease in amortization
of initial  direct  costs of $326,889 or 70%, a decrease in  management  fees of
$202,781 or 27%, a decrease in administrative  expense  remibursement of $96,862
or 26% and a decrease in provision for bad debt of $77,996 or 100%. The decrease
in interest  expense was due to a decrease in the average debt  outstanding from
1998 to 1999. The decreases in amortization of initial direct costs,  management
fees and administrative  expense  reimbursements  were a result of a decrease in
the average size of the finance lease  portfolio  from 1998 to 1999. As a result
of an  analysis  of  delinquency,  assessment  of  overall  risk and a review of
historical loss experience, the Partnership recorded a provision for bad debt of
$77,996  for the nine  months  ended  September  30,  1998.  Based on a  similar
analysis,  the Partnership  determined that no additional provision for bad debt
was required for the nine months ended September 30, 1999.

      Net income  for the nine  months  ended  September  30,  1999 and 1998 was
$1,108,255  and  $272,894,  respectively.  The net income per  weighted  average
limited  partnership  unit  outstanding  was  $2.89  and $.71 for 1999 and 1998,
respectively.

Liquidity and Capital Resources

      The  Partnership's  primary  sources  of funds for the nine  months  ended
September  30, 1999 and 1998 were net cash  provided by operations of $1,030,857
and $1,527,313, respectively, and proceeds from sales of equipment of $5,493,998
and $2,215,516,  respectively. These funds were used to fund cash distributions,
to make  payments  on  borrowings  and,  in 1998,  to  purchase  equipment.  The
Partnership  intends  to fund cash  distributions  utilizing  cash  provided  by
operations and to purchase additional equipment utilizing proceeds from sales of
equipment.

      Monthly cash  distributions  to limited partners for the nine months ended
September 30, 1999 and 1998 totaled $3,058,578 and $3,065,352,  respectively, of
which  $1,097,172  and  $270,165  was  investment   income  and  $1,961,406  and
$2,795,187 was a return of capital,  respectively.  The monthly  annualized cash
distribution  rate to limited  partners  was  10.75% in 1999 and 1998,  of which
3.86%  and .95% was  investment  income  and  6.89%  and  9.80%  was a return of
capital,  respectively.  The limited partner  distribution  per weighted average
unit  outstanding  in 1999 and  1998 was  $8.06,  of  which  $2.89  and $.71 was
investment income and $5.17 and $7.35 was a return of capital, respectively. The
proportion  of the  investment  income  distribution  relative  to the return of
capital distribution increased due to the growth of the Partnership's net income
over the prior period.

      As  of  September  30,  1999  there  were  no  known  trends  or  demands,
commitments,  events  or  uncertainties  which are  likely to have any  material
effect on liquidity. As cash is realized from operations, sales of equipment and
borrowings, the Partnership will invest in equipment leases and financings where
it deems it to be prudent while  retaining  sufficient  cash to meet its reserve
requirements and recurring obligations.

      In December  1998 the  Partnership  and three  affiliates,  ICON Cash Flow
Partners,  L.P.,  Series C ("Series C"), L.P. Seven and ICON Income Fund Eight A
L.P.  ("Eight A") formed ICON Boardman  Funding LLC ("ICON BF"), for the purpose
of acquiring a lease with Portland General Electric.  The purchase price totaled
$27,421,810,  and was  funded  with cash and  non-recourse  debt  assumed in the
purchase  price.  The  Partnership,  Series C, L.P. Seven and Eight A received a
 .5%, .5%, .5% and 98.5% interest,  respectively,  in ICON BF. The  Partnership's
original  investment was recorded at cost of $56,960 and will be adjusted by its
share of earnings, losses and distributions, thereafter. Simultaneously with the
acquisition of the Portland  General Electric lease by ICON BF, a portion of the
rent  receivable  in excess of the senior  debt  payments  was  acquired  by the
Partnership  from ICON BF for  $3,801,108.  On March 30, 1999, ICON BF exercised
its right to  acquire  the  Partnership's  investment  in a portion  of the rent
receivable  in excess of the senior debt payments for  $3,097,637  and financed,
with a third  party,  all of the rent  receivable  in excess of the senior  debt
payments. There was no gain or loss to the Partnership on this transaction. ICON
BF received $7,643,867 from the financing.  The proceeds from the financing, net
of the purchase of the Partnership's investment, were distributed to the members
of ICON BF in accordance with their ownership interests.

      In  August  1997 the  Partnership,  Series E and L.P.  Seven  formed  ICON
Receivables  1997-B LLC  ("1997-B"),  a special  purpose  entity  formed for the
purpose of originating  leases and securitizing its portfolio.  The Partnership,
Series  E and L.P.  Seven  contributed  $250,000  (8.33%  interest),  $2,250,000
(75.00%  interest) and $500,000 (16.67%  interest),  respectively to 1997-B.  In
order to fund the acquisition of leases,  1997-B obtained a warehouse  borrowing
facility  (the "1997-B  Warehouse  Facility")  from a lender.  In October  1998,
1997-B completed an equipment securitization. The net proceeds from

the  securitization  of these assets were used to pay-off the  remaining  1997-B
Warehouse  Facility  balance and any remaining  proceeds were distributed to the
1997-B members in accordance with their  membership  interests.  The Partnership
accounts for its investment in 1997-B under the equity method of accounting. The
Partnership's  original  investment  was recorded at cost and is adjusted by its
share of earnings, losses and distributions thereafter.

Year 2000 Issue

      The Year 2000 issue arose  because many  existing  computer  programs have
been written using two digits rather than four to define the applicable year. As
a result,  programs could interpret dates ending in "00" as the year 1900 rather
than the year  2000.  In  certain  cases,  such  errors  could  result in system
failures  or  miscalculations   that  disrupt  the  operation  of  the  affected
businesses.

      The Partnership uses computer  information systems provided by the General
Partner and has no computer information systems of its own. The software related
to the General  Partner's primary computer  information  systems are provided by
third party vendors.  The General Partner has formally  communicated  with these
vendors and has received  assurance that their programs are Year 2000 compliant.
In addition,  the General Partner has gathered  information  about the Year 2000
readiness of  significant  vendors and  third-party  servicers  and continues to
monitor  developments  in this area.  All of the  General  Partner's  peripheral
computer  technologies,  such as its  network  operating  system and third party
software  applications,  including  payroll and  electronic  banking,  have been
evaluated and have been found to be Year 2000 compliant.  The ultimate impact of
the Year 2000  issue on the  Partnership  will  depend to a great  extent on the
manner in which the issue is addressed by the Partnership's lessees. Each of the
Partnership's  lessees will have a material  self-interest in resolving any Year
2000 issue. However, non-compliance on the part of a lessee could result in lost
or  delayed  revenues  to the  Partnership.  The  effect  of  this  risk  to the
Partnership is not determinable.

      The General  Partner is  responsible  for costs relating to the assessment
and  development of its Year 2000  compliance  remediation  plan, as well as the
testing  of the  hardware  and  software  owned  or  licensed  for its  personal
computers.  The General  Partner's  costs  incurred to date and expected  future
costs are not material.
