NOTE 1 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
- ---------------------------------------------------
General
- -------
The accompanying  condensed unaudited  financial  statements have  been prepared
in accordance  with  accounting  principles  generally  accepted in  the  United
States of America for interim financial information and with the instructions to
Form 10-Q  for  quarterly  reports under Section 13 or 15(d) of  the  Securities
Exchange Act of 1934. Accordingly, they do not  include  all of the  information
and  footnotes  required  by accounting  principles  generally  accepted  in the
United States of America for complete financial statements. In  the  opinion  of
management,  all adjustments (consisting of normal recurring accruals)considered
necessary for a fair presentation have been included. Operating results  for the
three months ended June 30, 2005 are not necessarily  indicative  of the results
that may be expected for the fiscal  year  ending  March 31, 2006.  For  further
information, refer to the financial statements and footnotes thereto included in
the  Partnership's  annual  report  on  Form  10-K  for  the  fiscal year  ended
March 31, 2005.

Organization
- ------------
WNC Housing Tax Credit Fund IV, L.P., Series 1, a California Limited Partnership
(the "Partnership"), was formed on May 4, 1993 under the  laws  of the  state of
California, and commenced  operations on October 20, 1993. The  Partnership  was
formed to invest primarily  in  other  limited  partnerships (the "Local Limited
Partnerships") which own and operate multi-family housing complexes(the "Housing
Complex") that The local general partners (the "Local General Partners") of each
Local Limited Partnership retain responsibility for maintaining,  operating  and
managing the Housing Complex.

The general partner of the Partnership is WNC Tax  Credit Partners IV, L.P.("TCP
IV"). The general partner of TCP IV is WNC & Associates, Inc.("Associates"). The
chairman and president  own  substantially  all  of  the  outstanding  stock  of
Associates. The business of  the  Partnership  is  conducted  primarily  through
Associates as neither TCP IV nor  the  Partnership  have employees of their own.

The Partnership Agreement authorized the sale of up  to 10,000 units  at  $1,000
per Unit ("Units"). The offering of Units concluded in July 1994  at  which time
10,000 Units in the amount of $10,000,000 had been accepted. The General Partner
has 1% interest in operating profits and losses, taxable income and  losses,cash
available for  distribution  from the  Partnership and tax credits. The  limited
partners will be allocated the remaining 99% of  these  items in  proportion  to
their respective investments.

After the Limited Partners have received  proceeds from  a sale  or  refinancing
equal to their capital contributions and  their return on investment (as defined
in the Partnership Agreement) and the  General  Partner  has  received  proceeds
equal to its capital contribution and subordinated disposition fee (as described
in Note 3) from the remainder, any additional sale or refinancing remainder, any
additional sale or refinancing proceeds  will be distributed  90% to the Limited
Partners (in  proportion  to  their  respective   investments)  and 10%  to  the
General Partner.

Certain Risks and Uncertainties
- -------------------------------
An investment in the Partnership and  the  Partnership's  investments  in  Local
Limited Partnerships and their  Housing Complexes  are  subject  to risks. These
risks may impact the tax benefits of an investment  in  the  amount  of proceeds
available  for  distribution  to  Partnership, and  the  Partners,  if  any,  on
liquidation of the Partnerships investments.  Some of those  risks  include  the
following:

The  Low  Income   Housing  Tax  Credits   rules  are   extremely   complicated.
Noncompliance with these rules results in the loss of future Low Income  Housing
Tax Credits and the fractional  recapture of  Low  Income  Housing  Tax  Credits
already taken. In

NOTE 1 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES, continued
- --------------------------------------------------------------
most cases the  annual  amount  of  Low  Income  Housing  Tax  Credits  that  an
individual can use is limited to the tax  liability  due  on  the  person's last
$25,000 of taxable income. The  Local Limited  Partnerships  may  be  unable  to
sell the Housing Complexes at a price which  would  result  in  the  Partnership
realizing cash distributions  or  proceeds  from  the  transaction. Accordingly,
the Partnership may be unable to distribute any cash to  its  limited  partners.
Low Income Housing Tax Credits may be the only benefit from an investment in the
Partnership.

The Partnership has invested in a limited number of Local  Limited Partnerships.
Such limited diversity means that  the  results  of  operation  of  each  single
Housing Complex will have a greater  impact  on  the  Partnership. With  limited
diversity,  poor  performance  of  one   Housing   Complex   could   impair  the
Partnership's ability to satisfy its investment objectives. Each Housing Complex
is subject to mortgage indebtedness. If a Local Limited  Partnership  failed  to
pay  its  mortgage, it  could  lose  its  Housing  Complex  in  foreclosure.  If
foreclosure were to occur during the first 15 years, the  loss of any  remaining
future Low Income Housing  Tax Credits, a  fractional  recapture  of  prior  Low
Income Housing Tax Credits, and a loss of the  Partnership's investment  in  the
Housing Complex would occur. The Partnership is a  limited  partner  or  a  non-
managing member  of each Local Limited Partnership. Accordingly, the Partnership
will have very limited rights with respect to  management of  the Local  Limited
Partnerships. The Partnership will rely totally on  the Local  General Partners.
Neither the Partnership's investments in  Local  Limited  Partnerships  nor  the
Local  Limited  Partnerships' investments  in  Housing  Complexes   are  readily
marketable. To the extent the Housing  Complexes receive government financing or
operating subsidies, they may be subject to one or more of the  following risks:
difficulties in obtaining tenants  for  the  Housing  Complexes; difficulties in
obtaining rent increases; limitations  on  cash  distributions;  limitations  on
sales or refinancing of Housing Complexes; limitations on transfers of interests
in Local Limited Partnerships; limitations on removal of Local General Partners;
limitations on subsidy programs; and possible changes in applicable regulations.
Uninsured casualties could result in loss of property and Low Income Housing Tax
Credits and recapture of Low Income Housing  Tax Credits  previously  taken. The
value of real estate is subject to  risks from fluctuating  economic conditions,
including employment rates, inflation, tax, environmental, land use  and  zoning
policies, supply and demand of similar properties, and  neighborhood conditions,
among others.

The  ability of Limited  Partners to claim tax losses  from the  Partnership  is
limited.  The IRS may audit the  Partnership or a Local Limited  Partnership and
challenge the tax treatment of tax items.  The amount of Low Income  Housing Tax
Credits and tax losses allocable to the limited partners could be reduced if the
IRS were  successful  in such a  challenge.  The  alternative  minimum tax could
reduce tax benefits from an investment in the  Partnership.  Changes in tax laws
could also impact the tax benefits from an investment in the Partnership  and/or
the value of the Housing Complexes.

Substantially  all of the Low  Income  Housing  Tax  Credits  anticipated  to be
realized from the Local Limited Partnerships have been realized. The Partnership
does not anticipate  being allocated a significant  amount of Low Income Housing
Tax Credits from the Local Limited  Partnerships in the future.  Until the Local
Limited  Partnerships  have  completed the 15 year Low Income Housing Tax Credit
compliance  period,  risks  exist for  potential  recapture  of prior Low Income
Housing Tax Credits.

No trading  market  for the Units  exists or is  expected  to  develop.  Limited
Partners  may be unable to sell  their  Units  except at a  discount  and should
consider their Units to be a long-term  investment.  Individual limited partners
will have no recourse if they disagree with actions  authorized by a vote of the
majority of Limited Partners.

NOTE 1 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES, continued
- --------------------------------------------------------------
Anticipated  future and  existing  cash  resources  of the  Partnership  are not
sufficient   to  pay  existing   liabilities   of  the   Partnership.   However,
substantially all of the existing  liabilities of the Partnership are payable to
the General  Partner and/or its  affiliates.  Though the amounts  payable to the
General Partner and/or its affiliates are contractually  currently payable,  the
Partnership  anticipates that the General Partner and/or its affiliates will not
require the payment of these contractual  obligations until capital reserves are
in excess of the aggregate of then  existing  contractual  obligations  and then
anticipated future foreseeable  obligations of the Partnership.  The Partnership
would be adversely  affected  should the General  Partner  and/or its affiliates
demand current  payment of the existing  contractual  obligations and or suspend
services for this or any other reason.

Method of Accounting for Investments in Limited Partnerships
- ------------------------------------------------------------
The Partnership  accounts for its investments in limited  partnerships using the
equity method of  accounting,  whereby the  Partnership  adjusts its  investment
balance for its share of the Local Limited  Partnerships'  results of operations
and for any  contributions  made and  distributions  received.  The  Partnership
reviews the  carrying  amount of an  individual  investment  in a Local  Limited
Partnership for possible  impairment whenever events or changes in circumstances
indicate that the carrying  amount of such  investment  may not be  recoverable.
Recoverability  of such investment is measured by the estimated value derived by
management,  generally  consisting of the sum of the remaining future Low Income
Housing  Tax  Credits  estimated  to be  allocated  to the  Partnership  and the
estimated  residual value to the Partnership.  If an investment is considered to
be impaired,  the impairment to be recognized is measured by the amount by which
the  carrying  amount of the  investment  exceeds  fair  value.  The  accounting
policies of the Local Limited  Partnerships are generally  consistent with those
of  the  Partnership.  Costs  incurred  by  the  Partnership  in  acquiring  the
investments  are  capitalized  as part of the  investment  account and are being
amortized over 30 years (see Note 2).

Equity in losses of Limited Partnerships for the periods ended June 30, 2005 and
2004 have been  recorded by the  Partnership  based on three  months of reported
results  estimated by management of the Partnership.  Management's  estimate for
the three-month  period is based on either actual unaudited  results reported by
the Local Limited  Partnerships  or historical  trends in the  operations of the
Local Limited  Partnerships.  In subsequent  annual financial  statements,  upon
receiving the actual annual results reported by the Local Limited  Partnerships,
management  reverses its prior estimate and records the actual results  reported
by  the  Local  Limited   Partnerships.   Equity  in  losses  from  the  Limited
Partnerships  allocated to the Partnership are not recognized to the extent that
the  investment  balance would be adjusted below zero. As soon as the investment
balance  reaches  zero,  amortization  of the  related  costs of  acquiring  the
investment are  accelerated  to the extent of losses  available (see Note 2). If
the  Local  Limited   Partnerships  report  net  income  in  future  years,  the
Partnership  will resume applying the equity method only after its share of such
net income  equals the share of net losses not  recognized  during the period(s)
the equity method was suspended.

Distributions  received by limited  partners are accounted for as a reduction of
the investment balance.  Distributions received after the investment has reached
zero are recognized as income.

Offering Expenses
- -----------------
Offering  expenses consist of underwriting  commissions,  legal fees,  printing,
filing and  recordation  fees,  and other costs  incurred  with selling  limited
partnership  interests in the Partnership.  WNC is obligated to pay all offering
and  organization  costs in excess of 15% (including  sales  commissions) of the
total  offering  proceeds.  Offering  expenses  are  reflected as a reduction of
limited  partners'  capital  and  amounted to $946,704 at the end of all periods
presented.

                       (A California Limited Partnership)

                     NOTES TO FINANCIAL STATEMENTS-Continued

                       For the Quarter Ended June 30, 2005
                                   (unaudited)



NOTE 1 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES, continued
- --------------------------------------------------------------
Exit Strategy
- -------------
The IRS  compliance  period for Low Income  Housing  Tax  Credit  properties  is
generally  15 years from  occupancy  following  construction  or  rehabilitation
completion.  WNC was one of the first in the industry to offer investments using
the tax credit.  Now these very first programs are completing  their  compliance
period.

With that in mind, we are continuing our review of the  Partnership's  holdings,
with special  emphasis on the more mature  properties  including those that have
satisfied the IRS compliance requirements. Our review will consider many factors
including  extended  use  requirements  on the  property  (such as those  due to
mortgage  restrictions  or state  compliance  agreements),  the condition of the
property,  and the tax consequences to the limited partners from the sale of the
property.

Upon identifying  those  properties with the highest  potential for a successful
sale, refinancing or syndication, we expect to proceed with efforts to liquidate
those  properties.  Our  objective is to maximize the Limited  Partners'  return
wherever  possible  and,  ultimately,  to wind down  those  funds that no longer
provide tax benefits to Limited  Partners.  However,  Local Limited  Partnership
interests may be disposed at any time by Associates in its  discretion.  To date
no properties in the Partnership have been selected for disposition.

Use of Estimates
- ----------------
The preparation of financial statements in conformity with accounting principles
generally  accepted in the United States of America 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 revenues and expenses
during the reporting  period.  Actual results could materially differ from those
estimates.

Concentration of Credit Risk
- ----------------------------
At June 30,  2005,  the  Partnership  maintained  a cash  balance  at a  certain
financial institution in excess of the maximum federally insured amounts.

Net Loss Per Limited Partner Unit
- ---------------------------------
Net loss per limited  partnership  unit is  calculated  pursuant to Statement of
Financial  Accounting  Standards No. 128,  Earnings Per Share. Net loss per unit
includes no dilution  and is computed  by  dividing  loss  available  to limited
partners by the weighted average number of units outstanding  during the period.
Calculation of diluted net loss per unit is not required.

Income Taxes
- ------------
No provision  for income taxes has been recorded in the  accompanying  financial
statements  as any  liability  and/or  benefits for income taxes as income taxes
flows to the partners of the Partnership and is their obligation and/or benefit.
For income tax purposes the Partnership reports on a calendar year basis.

Reporting Comprehensive Income
- ------------------------------
The  Statement of Financial  Accounting  Standards  ("SFAS") No. 130,  Reporting
Comprehensive  Income  established  standards  for the  reporting and display of
comprehensive  income (loss) and its components in a full set of general-purpose
financial statements. The Partnership had no items of other comprehensive income
for all periods presented, as defined by SFAS No. 130.

NOTE 1 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES, continued
- --------------------------------------------------------------
New Accounting Pronouncements
- -----------------------------
As of March 31,  2004,  the  Partnership  adopted FASB  Interpretation  No. 46 -
Revised,  Consolidation  of  Variable  Interest  Entities  ("FIN46R").  FIN  46R
provides  guidance as to when a company should include the assets,  liabilities,
and  activities  of  a  variable   interest  entity  ("VIE")  in  its  financial
statements,   and  when  a  company  should  disclose   information   about  its
relationship  with a VIE. A VIE is a legal structure used to conduct  activities
or hold assets, and a VIE must be consolidated by a company if it is the primary
beneficiary  because a primary  beneficiary absorbs the majority of the entity's
expected losses, the majority of the expected residual returns, or both.

Under FIN 46R, the Local Limited  Partnerships in which the Partnership  invests
are VIEs. However,  management does not consolidate the Partnership's  interests
in these VIE's under FIN46R,  as the  Partnership  is not considered the primary
beneficiary.  Rather,  the  Partnership  currently  records  the  amount  of the
investment in the Local Limited  Partnerships  as an asset in the balance sheet,
and  recognizes  its share of Local  Limited  Partnership  income or loss in the
statement of operations.

The Partnership's balance in its investment in Local Limited Partnerships,  plus
the risk of recapture of tax credits previously recognized on these investments,
represents its maximum exposure to loss. The  Partnership's  exposure to loss is
mitigated  by  the  condition  and  financial   performance  of  the  underlying
properties,  as well as the  strength of the Local  General  Partners  and their
guarantee against credit recapture.

In May 2005, the FASB issued Statement of Financial Accounting Standards No. 154
(SFAS 154),  "Accounting Changes and Error Corrections" which provides guidance
on the  accounting  for and  reporting of accounting  changes and  correction of
errors.  This  statement  changes the  requirements  for the  accounting for and
reporting  of a change in  accounting  principle  and  applies to all  voluntary
changes in  accounting  principle.  It also  applies to changes  required  by an
accounting pronouncement in the unusual instance that the pronouncement does not
include  specific  transition  provisions.   This  statement  is  effective  for
accounting  changes and  corrections  of errors made in fiscal  years  beginning
after December 15, 2005. The  Partnership  does not anticipate a material effect
upon the adoption of this statement.




NOTE 2 - INVESTMENTS IN LIMITED PARTNERSHIPS
- --------------------------------------------
As of the periods  presented,  the Partnership had acquired limited  partnership
interests  in  twenty-one  Local  Limited  Partnerships,  each of which owns one
housing  complex,  consisting  of an  aggregate  of  812  apartment  units.  The
respective General Partners of the Local Limited  Partnerships manage the day to
day operations of the entities.  Significant Local Limited Partnership  business
decisions require approval from the Partnership.  The Partnership,  as a limited
partner,  is  generally  entitled  to 99%,  as  specified  in the Local  Limited
Partnership agreements,  of the operating profits and losses, taxable income and
losses and tax credits of the Local Limited Partnerships.

                       (A California Limited Partnership)

                    NOTES TO FINANCIAL STATEMENTS - CONTINUED

                       For the Quarter Ended June 30, 2005
                                   (unaudited)


NOTE 2 - INVESTMENTS IN LIMITED PARTNERSHIPS, continued
- -------------------------------------------------------
Certain Local Limited  Partnerships have incurred  significant  operating losses
and/or have  working  capital  deficiencies.  In the event  these Local  Limited
Partnerships continue to incur significant operating losses,  additional capital
contributions  by the  Partnership  and/or  the Local  General  Partners  may be
required  to sustain  the  operations  of such Local  Limited  Partnerships.  If
additional  capital  contributions  are not made  when  they are  required,  the
Partnership's  investment in certain of such Local Limited Partnerships could be
impaired, and the loss and recapture of the related tax credits could occur.

NOTE 3 - RELATED PARTY TRANSACTIONS
- -----------------------------------
The Partnership has no officers,  employees,  or directors.  However,  under the
terms of the  Partnership  Agreement the Partnership is obligated to the General
Partner or its affiliates for the following items:

(a)  Annual Asset  Management  Fee. An annual asset  management fee equal to the
     greater amount of (i) $2,000 for each apartment complex,  or (ii) 0.275% of
     gross  proceeds.  The base fee amount  will be adjusted  annually  based on
     changes to the Consumer Price Index.  However,  in no event will the annual
     asset  management  fee  exceed  0.2% of the  invested  assets  of the Local
     Limited  Partnerships,  including the Partnership's  allocable share of the
     mortgages.  Asset  management fees of $10,500 were incurred for each of the
     three months ended June 30, 2005 and 2004. The Partnership paid $18,750 and
     $7,500 of those asset  management  fees for the three months ended June 30,
     2005 and 2004, respectively.

(b)  Subordinated  Disposition Fee. A subordinated  disposition fee is an amount
     equal to 1% of the sales price of real estate sold.  Payment of this fee is
     subordinated to the Limited  Partners  receiving a preferred  return of 16%
     through  December 31, 2004 and 6% thereafter (as defined in the Partnership
     Agreement)  and is payable  only if the General  Partner or its  affiliates
     render services in the sales effort

(c)  The  Partnership  reimburses  the  General  Partner or its  affiliates  for
     operating expenses incurred in behalf of the Partnership. Operating expense
     reimbursements  are  approximately  $7,900 and $0 during  the three  months
     ended June 30, 2005 and 2004, respectively.

The accrued  fees and  advances  due to General  Partner  and/or its  affiliates
consisted of the following:


                                                                      June 30, 2005               March 31, 2005
                                                                  ----------------------        --------------------
                                                                                      
       Reimbursement for expenses paid by the General
          Partner and/or its affiliate                         $                  1,470      $                7,902

NOTE 4 - PAYABLE TO LIMITED PARTNERSHIP
- ---------------------------------------
Payables to Limited  Partnerships  represent  amounts,  which are due at various
times based on conditions specified in the Limited Partnership Agreement.  These
contributions  are  payable  in  installments  and  are  due  upon  the  Limited
Partnership  achieving certain operating and development  benchmarks  (generally
within two years of the Partnership's initial investment).

                       For the Quarter Ended June 30, 2005

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

Forward-Looking Statements

With  the  exception  of  the  discussion  regarding   historical   information,
"Management's  Discussion  and  Analysis of Financial  Condition  and Results of
Operations"  and  other   discussions   elsewhere  in  this  Form  10-Q  contain
forward-looking  statements.  Such statements are based on current  expectations
subject to uncertainties and other factors,  which may involve known and unknown
risks that could cause actual  results of operations to differ  materially  from
those, projected or implied.  Further,  certain  forward-looking  statements are
based upon assumptions about future events, which may not prove to  be accurate.

Risks and uncertainties inherent in forward-looking  statements include, but are
not  limited  to,  our  future  cash  flows and  ability  to  obtain  sufficient
financing, level of operating expenses, conditions in the low-income housing tax
credit property market and the economy in general, as well as legal proceedings.
Historical  results are not necessarily  indicative of the operating results for
any future period.

Subsequent  written and oral  forward-looking  statements  attributable to us or
persons  acting on our behalf  are  expressly  qualified  in their  entirety  by
cautionary  statements  in this Form 10-Q and in other reports we filed with the
Securities and Exchange  Commission.  The following discussion should be read in
conjunction  with the condensed  unaudited  Financial  Statements  and the Notes
thereto included elsewhere in this filing.

The following discussion and analysis compares the results of operations for the
three  months  ended June 30, 2005 and 2004,  and should be read in  conjunction
with the condensed  financial  statements and accompanying notes included within
this report.

Financial Condition

The  Partnership's  assets at June 30, 2005  consisted  primarily of $170,000 in
cash and aggregate  investments in the twenty-one Local Limited  Partnerships of
$1,111,000.  Liabilities  at June 30, 2005  consisted  primarily  of $162,000 in
accrued asset annual  management fees and reimbursement for expenses paid by the
General Partner and its affiliates.

Results of Operations

Three Months  Ended June 30, 2005  Compared to Three Months Ended June 30, 2004.
The  Partnership's  net loss  for the  three  months  ended  June  30,  2005 was
$(17,000),  reflecting a decrease of $16,000 from the net loss  experienced  for
the three months ended June 30, 2004 of  $(33,000).  The decrease in net loss is
primarily due to equity in losses of Local Limited  Partnerships which decreased
by $10,000 to $(9,000) for the three  months ended June 30, 2005 from  $(19,000)
for the three months  ended June 30,  2004.  The decrease in equity in losses of
Local Limited  Partnerships is due to the  Partnership  not recognizing  certain
losses of the Local Limited Partnerships.  The investments in such Local Limited
Partnerships had reached $0 at June 30, 2005. Since the Partnership's  liability
with respect to its  investments is limited,  losses in excess of investment are
not  recognized.  Along with the  decrease in equity in losses of Local  Limited
Partnerships,  the loss from  operations  decreased by  approximately  $6,000 to
$(8,000) for the three months ended June 30, 2005 from  $(14,000)  for the three
months  ended June 30,  2004,  which was  contributed  to a $1,000  increase  in
distribution  income,  $2,000  increase in  reporting  fee income,  along with a
$1,000  decrease  in  amortization  and a $2,000  decrease  in  other  operating
expenses for the three months ended June 30, 2005.

                                       14




Cash Flows

Three months  Ended June 30, 2005  Compared to Three months Ended June 30, 2004.
Net cash used during the three months ended June 30, 2005 was $(21,000) compared
to net cash  used by the three  months  ended  June 30,  2004 of  $(8,000).  The
increase in cash used was primarily due to an increase in cash used by operating
activities  of  approximately  $(10,000)  which  included a $16,000  decrease in
accrued  fees and  expense  due to General  Partner  and its  affiliates,  and a
decrease in cash  provided by  investing  activities  of $(3,000)  for the three
months ended June 30, 2005.

During the three months ended June 30, 2005,  accrued  payables,  which  consist
primarily  of related  party  management  fees and  advances  due to the General
Partner, increased by approximately $15,000.

The Partnership  expects its future cash flows,  together with its net available
assets at June 30, 2005,  to be  sufficient  to meet all  currently  foreseeable
future cash requirements.

Item 3.  Quantitative and Qualitative Disclosures about Market Risk

         NOT APPLICABLE

Item 4.  Procedures and Controls

As of the end of the period covered by this report,  the  Partnership's  General
Partner, under the supervision and with the participation of the Chief Executive
Officer and Chief Financial  Officer of Associates  carried out an evaluation of
the effectiveness of the Fund's "disclosure  controls and procedures" as defined
in  Securities  Exchange  Act of 1934  Rule  13a-15  and  15d-15.  Based on that
evaluation,  the Chief  Executive  Officer  and  Chief  Financial  Officer  have
concluded  that  as of  the  end of the  period  covered  by  this  report,  the
Partnership's  disclosure controls and procedures were adequate and effective in
timely  alerting  them  to  material  information  relating  to the  Partnership
required to be included in the Partnership's periodic SEC filings.

Changes  in  internal  controls.  There  were no  changes  in the  Partnership's
internal control over financial reporting that occurred during the quarter ended
June 30, 2005 that materially  affected,  or are reasonably likely to materially
affect, the Partnership's internal control over financial reporting.
