THE WILLOWBRIDGE FUND L.P.NOTES TO CONDENSED FINANCIAL
STATEMENTSFor the Six  Months Ended June 30, 2006 and 2005(Unaudited)_______________

1.             
BASIS OF PRESENTATION

The interim condensed financial statements of The Willowbridge Fund L.P. (the Partnership) included herein have been prepared in accordance with accounting principles generally accepted in the United States of America for interim financial information and Rule 10-01 of Regulation S-X.  Accordingly, they do not include all the information and footnotes required by generally accepted accounting principles for complete annual financial statements. These condensed financial statements are unaudited and should be read in conjunction with the audited financial statements and notes thereto included in the Partnerships Annual Report on Form 10-K for the year ended December 31, 2005.  The Partnership follows the same accounting policies in the preparation of interim reports as set forth in the annual report.  In the opinion of management, the financial statements reflect all
adjustments, which are of a normal recurring nature, necessary for a fair presentation of the financial position, results of operations and changes in partners capital for the interim periods presented and are not necessarily indicative of a full years results.

2.              PARTNERSHIP
ORGANIZATION

The Willowbridge Fund L.P. (the Partnership), a Delaware limited partnership, was organized on January 24, 1986.  The Partnership may engage in the speculative trading of commodity futures contracts, options on commodities or commodity futures contracts and forward contracts.  Ruvane Fund Management Corporation (formerly named Ruvane Investment Corporation) is the general partner of the Partnership (the General Partner) and is registered as a Commodity Pool Operator and an Introducing Broker with the Commodity Futures Trading Commission.  The General Partner is required by the Limited Partnership Agreement, as amended and restated (the Agreement), to contribute an amount equal to one percent of the aggregate capital raised by the Partnership.

In accordance with the amendment to Section 5 of the Agreement, effective January 16, 2003, the Partnership offers separate classes of limited partnership interests, whereby interests which were issued by the Partnership prior to January 16, 2003 are designated as Class A interests.  The Partnership also offers Class B limited partnership interests through a private offering pursuant to Regulation D as adopted under section 4(2) of the Securities Act of 1933, as amended.  The Partnership will offer the Class B interests up to an aggregate of $100,000,000.  The Partnership began issuing Class B interests in 2004.  Commissions and redemption charges for the Class B interests differ from those of the Class A interests, but in all other respects the Class A interests and the Class B interests are identical.  The Class A interests and Class B interests are traded pursuant to the same trading program.

The Partnership shall end upon withdrawal, insolvency or dissolution of the General Partner or a decline of greater than fifty percent of the net assets of the Partnership as defined in the Agreement, or the occurrence of any event which shall make it unlawful for the existence of the Partnership to be continued.

3.              SIGNIFICANT
ACCOUNTING POLICIES

A.            Cash
and Cash Equivalents

The Partnership has defined cash and
cash equivalents as cash and short-term, highly liquid investments with
maturities of three months or less when acquired.

B.             Due
from Broker

Due from broker represents cash required to meet margin requirements and excess funds not required for margin which are typically invested in 30 day commercial paper and U.S. Treasury bills which are carried at cost plus accrued interest, which approximates market value.  The Partnership is subject to credit risk to the extent any broker with whom  the Partnership conducts business is unable to deliver cash balances or securities, or clear securities transactions on the Partnerships behalf.  The General Partner monitors the financial condition of the brokers with which the Partnership conducts business and believes that the likelihood of loss under the aforementioned circumstances is remote.

C.            
Revenue Recognition

Investments in commodity futures contracts are recorded on the trade date and open contracts are recorded in the financial statements at their fair value on the last business day of the reporting period.  The difference between the original cost basis of the contract and fair value is recorded as an unrealized gain or loss on open positions on the Condensed Statements of Financial Condition.  Realized gains and losses on closed contracts are recorded on a first-in-first-out basis.  Interest income is recognized on an accrual basis. All commodity futures contracts and financial instruments are recorded at fair value based on quoted market prices.

D.            
Commissions

The Class A partners pay to the General Partner a flat rate commission of 4.0 percent annually of the net asset value of the Class A partners capital as of the beginning of each month.  Class B limited partners pay to the General Partner a flat rate commission of up to 6.0 percent annually of the net asset value of the Class B partners capital.  From these amounts, the General Partner will pay or reimburse the Partnership for actual trading commissions incurred by the Partnership and will pay up to 3.0 percent from this amount to properly registered selling agents as their ongoing compensation for servicing Class B limited partners.

include professional fees, bookkeeping costs and other charges such as
registration fees, printing costs and bank fees.

J.

3.             SIGNIFICANT
ACCOUNTING POLICIES (CONTINUED)

L.            
Redemptions

Limited partners may redeem some or all of their units at net asset value per unit as of the last business day of each month on at least ten days written notice to the General Partner.  Class B interests are subject to an early redemption charge of up to 4 percent if such interests are redeemed within 12 months of their purchase.

M.           
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 income (loss) and expenses during the reporting period. Estimates include accrual of administrative expenses.  Actual results could differ from these estimates.

N.            
Recently Issued Accounting Pronouncements

In February 2006, the FASB issued Statement of Financial Accounting Standards No. 155, Accounting for Certain Hybrid Financial Instruments (FAS 155).  This statement amends FASB Statement No. 133, Accounting for Derivative Instruments and Hedging Activities, and No. 140, Accounting for Transfers and Servicing of Financial Assets and Extinguishment of Liabilities.  FAS 155 primarily relates to accounting for derivative financial instruments involved in hedging activities.  FAS 155 is effective for all financial instruments acquired or issued after the beginning of an entitys first fiscal year that begins after September 15, 2006.  The implementation of FAS 155 is not expected to have a material impact on the Partnerships financial statements.

O.           
Indemnifications

The Partnership has entered into agreements, which provide for the indemnifications against losses, costs, claims and liabilities arising from the performance of their individual obligations under such agreements, except for gross negligence or bad faith.  The Partnership has had no prior claims or payments pursuant to these agreements.  The Partnerships individual maximum exposure under these arrangements is unknown, as this would involve future claims that may be made against the Partnership that have not yet occurred. However, based on previous experience, the Partnership expects the risk of loss to be remote.

THE
WILLOWBRIDGE FUND L.P.NOTES TO CONDENSED FINANCIAL STATEMENTS
(CONTINUED)For the Three Months Ended June 30, 2006 and 2005
(Unaudited)_______________

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

General

The Willowbridge Fund L.P. (the "Partnership") engages in the speculative trading of commodity futures contracts, options on commodities or commodity futures contracts and forward contracts ("Commodity Interests"). The objective of the Partnership is the appreciation of its assets through speculative trading. Ruvane Fund Management Corporation (formerly named Ruvane Investment Corporation) is the General Partner of the Partnership (the "General Partner") and Willowbridge Associates, Inc. is the Partnership's trading advisor (the "Advisor").

The success of the Partnership is dependent upon the ability of the Advisor to generate trading profits through the speculative trading of Commodity Interests sufficient to produce capital appreciation after payment of all fees and expenses. Future results will depend in large part upon the Commodity Interests markets in general, the performance of its advisor, the amount of additions and redemptions and changes in interest rates. Due to the highly leveraged nature of the Partnership's trading activity, small price movements in Commodity Interests may result in substantial gains or losses to the Partnership. Because of the nature of these factors and their interaction, past performance is not indicative of future results. As a result, any recent increases in net realized or unrealized gains may have no bearing on any results that may be obtained in the future.

The Partnership incurs substantial charges from the payment of brokerage commissions to the General Partner, payment of management and incentive fees to the Advisor, payment of management fees to the General Partner and administrative expenses. The Partnership is required to make trading profits to avoid depleting and exhausting its assets from the payment of such fees and expenses.

The markets in which the Commodity Interests trade are constantly changing in character and in degree of volatility. Although the Advisor has been the sole advisor trading on behalf of the Partnership since April 1991, the General Partner continues to evaluate and analyze from both quantitative and qualitative perspectives the ability of the Advisor to trade effectively on the Partnership's behalf in the context of the current market environment. The General Partner seeks to limit market and credit risks by monitoring daily income and margin levels. The General Partner also relies upon the risk management strategies inherent in the Advisor's trading programs. In the future, the General Partner may utilize additional strategies or appoint additional advisors to trade on behalf of the Partnership.

Class A Interests paid to the General Partner a flat-rate monthly brokerage commission of approximately 0.29% of the net asset value of the Class A Interests as of the beginning of each month (a 3.5% annual rate) for the period, January 1, 2001 to July 31, 2002. Beginning August 1, 2002, the Class A Interests pay to the General Partner a flat-rate monthly brokerage commission of approximately 0.33% of the net asset value of the Class A Interests as of the beginning of each month (a 4.0% annual rate).

Class B Interests pay to the General Partner commission of up to 6.0 percent annually of the net asset value of the Class B partners' capital. The General Partner will pay up to 3.0 percent from this amount to properly registered selling agents as their compensation, and to the extent the amount is less than 3% the brokerage fee with respect to such Class B limited partnership interests will be reduced accordingly. The General Partner pays from this amount all commission charges and fees with respect to the Partner's trading in Commodity Interests. The flat-rate monthly commission is common among programs such as the Partnership.

Summary of Critical Accounting Policies

The preparation of financial statements in
conformity with accounting principles generally accepted in the United States of
America ("GAAP") requires management to adopt accounting policies and make
estimates and assumptions that affect amounts reported in the Partnership's
financial statements. The critical accounting estimates and related judgments
underlying the Partnership's financial statements are summarized below. In
applying these policies, management makes judgments that frequently require
estimates about matters that are inherently uncertain. The Partnership's
significant accounting policies are described in detail in Note 3 of the Notes
to the Condensed Financial Statements.

Investments in commodity futures, options and
forward contracts are recorded on the trade date and open contracts are recorded
in the financial statements at their fair value on the last business day of the
reporting period. The difference between the original cost basis of the contract
and fair value is recorded in income as a net unrealized gain on open
positions  on the
Condensed Statements of Financial Condition. Realized gains and losses on closed
contracts are recorded on a first-in-first-out basis. Interest income is
recognized on an accrual basis. All Commodity Interests and financial instruments are recorded at fair value in the financial
statements. Fair value is based on quoted market prices or estimates of fair
value.



11

The Partnership records all investments at fair
value in its financial statements, with changes in fair value reported as a
component of Trading Profits (Losses) in the Condensed Statements of  Loss.
Generally, fair values are based on quoted market prices; however, in certain
circumstances, significant judgments and estimates are involved in determining
fair value in the absence of an active market closing price.

Results of Operations

Comparison of the Three Months Ended June 30, 2006 and 2005

Liquidity and Capital Resources
In general, the Advisor trades only those Commodity Interests that have sufficient liquidity to enable it to enter and close out positions without causing major price movements. Notwithstanding the foregoing, most United States commodity exchanges limit the amount by which certain commodities may move during a single day by regulations referred to as "daily price fluctuation limits" or "daily limits." Pursuant to such regulations, no trades may be executed on any given day at prices beyond daily limits the price of a futures contract occasionally has exceeded the daily limit for several consecutive days, with little or no trading, thereby effectively preventing a party From liquidating its position. While the occurrence of such an event may reduce or eliminate the liquidity of a particular market, it will not eliminate losses and may, in fact, substantially increase losses because of the
inability to liquidate unfavorable positions. In addition, if there is little or no trading in a particular futures or forward contract that the Partnership is trading, whether such liquidity is caused by any the above reasons or otherwise, the Partnership may be unable to liquidate its position prior to its expiration date, thereby requiring the Partnership to make or take delivery of the underlying interests of the Commodity Interests.
The Partnership's capital resources are dependent upon three factors: (a) the income or losses generated by the Advisor; (b) the capital invested or redeemed by the limited partners; and (c) the capital invested or redeemed by the General Partner. The Partnership sells limited partnership units to investors from time to time in private placements pursuant to Regulation D of the Securities Act of 1933, as amended. As of the last day of any month, a limited partner may redeem all of its limited partnership units on 10 days' prior written notice to the General Partner.
The General Partner must maintain a capital account in such amount as is necessary for the General Partner to maintain a one percent (1%) interest in the capital, income and losses of the Partnership. All capital contributions by the General Partner necessary to maintain such capital account balance are evidenced by units of general partnership interest, each of which has an initial value equal to the net asset value per unit at the time of such contribution. The General Partner may withdraw any excess above its required capital contribution without notice to the limited partners and may also contribute any greater amount to the Partnership.

Item 3. Quantitative and Qualitative Disclosures About
Market Risk.
The Partnership is a commodity pool engaged in the speculative trading of commodity futures contracts (including agricultural and non-agricultural commodities, currencies and financial instruments), options on commodities or commodity futures contracts, and forward contracts. The risk of market sensitive instruments is integral to the Partnership's primary business activities. The futures interests traded by the Partnership involve varying degrees of related market risk. Such market risk is often dependent upon changes in the level or volatility of interest rates, exchange rates, and/or market values of financial instruments and commodities. Fluctuations in related market risk based upon the aforementioned factors result in frequent changes in the fair value of the Partnership's open positions, and, consequently, in its earnings and cash flow. The Partnership accounts for open positions on a timely basis of
market-to-market accounting principles. As such, any gain or loss in the fair value of the Partnership's open positions is directly reflected in the Partnership's earnings, whether realized or unrealized. The Partnership's total market risk is influenced by a wide variety of factors including the diversification effects among the Partnership's existing open positions, the volatility present within the markets and tie liquidity of the markets. At varying times, each of these factors may act to exacerbate or mute the market risk associated with the Partnership. The following were the primary trading risk exposures of the Partnership as of June 30, 2006, by market sector:
Interest Rate
Interest rate risk is a significant market exposure of the Partnership. Interest rate movements in one country as well as relative interest rate movements between countries materially impact the Partnership's profitability. The Partnership's primary interest rate exposure is to interest rate fluctuations in the United States and the other- G-7 countries. The General Partner anticipates that G-7 interest rates will remain the primary market exposure of the Partnership for the foreseeable future.
Currency
The Partnership's currency exposure is to exchange rate fluctuations, primarily in the following countries: Germany, England, Japan, France, Switzerland, Australia, Canada and the United States of America. These fluctuations are influenced by interest rate changes as well as political and general economic conditions. The General Partner does not anticipate that the risk profile of the Partnership's currency sector will change significantly in the future.
Commodity
The Partnership's primary metals market exposure is to fluctuations in the price of gold, silver and copper. The Partnership also has commodity exposures in the price of soft commodities, which are often directly affected by severe or unexpected weather conditions. The General Partner anticipates that the Advisor will maintain an emphasis in the commodities described above. Additionally, the Partnership had exposure to the energy markets (natural gas, crude oil, heating oil and unleaded gasoline) as of June 30, 2006, and it is anticipated that positions in this sector will continue to be evaluated on an ongoing basis.
The
Partnership measures its market risk, related to its holdings of Commodity
Interests based on changes in interest rates, foreign currency rates, and
commodity prices utilizing a sensitivity analysis. The sensitivity analysis
estimates the potential change in fair values, cash flows and earnings based on
a hypothetical 10% change (increase and decrease) in interest, currency and
commodity prices. The Partnership used June 30, 2006 market rates and prices on
its instruments to perform the sensitivity analysis. The sensitivity analysis
has been prepared separately for each of the Partnership's market risk exposures
(interest rate, currency rate, and commodity price) instruments. The estimates
are based on the market risk sensitive portfolios described in the preceding
paragraph above. The potential loss in earnings is based on an immediate change
in:

14

    The prices of the Partnership's positions resulting from a 10% change in
    interest rates.
    The U.S. dollar equivalent balances of the Partnership's currency
    exposures due to a 10% shift in currency exchange rates.
    The market value of the Partnership's Commodity Interests due to a 10%
    change in the price of the Commodity Instruments. The Partnership has
    determined that the impact of a 10% change in market rates and
prices on its fair values, cash flows and earnings would not be material. The
Partnership has elected to disclose the potential loss to earnings of its
commodity price, interest rate and currency exchange rate sensitivity positions
as of June 30, 2006.The potential loss in earnings for each market
risk exposure as of  June 30, 2006 was approximately:

Commodity price risk
    $ 766,308Interest rate risk
    $ 657,726Currency exchange rate risk
    $ 623,303Item 4.  Controls and
Procedures
The President of the General Partner evaluated the effectiveness of the design and operation of the Partnership's disclosure controls and procedures, which are designed to insure that the Partnership's records, processes, summarizes and reports in a timely and effective manner the information required to be disclosed in the reports filed with or submitted to the Securities and Exchange Commission. Based upon this evaluation, the General Partner concluded that, as of June 30, 2006 the Partnership's disclosure controls are effective. There were no significant changes in the Partnership's internal controls or in other factors that could significantly affect those controls during the second quarter of 2006.
