RFMC WILLOWBRIDGE FUND, L.P.

NOTES TO CONDENSED FINANCIAL STATEMENTS

For the
Three Months Ended March 31, 2007 and 2006

(Unaudited)

_______________



1.
        BASIS OF PRESENTATION




The interim condensed financial statements of RFMC 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 accounting principles generally accepted in the United State of America (GAAP) 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, 2006.  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 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 $1,000 to 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 prior to January 16, 2003 by the Partnership will be 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; provided that the General
Partner may increase the amount of interests that will be offered in increments of $10,000,000 after notice to the limited partners.  Commissions and redemption charges for the Class B interests will differ from those of the Class A interests, but in all other respects the Class A interests and the Class B
interests will be identical.  The Class A interests and Class B interests will also be 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

3.
        SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)


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, based on quoted market prices.  The difference between the original cost basis of the contract and fair value is recorded as net 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 in the financial statements.



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.



Commissions charged to each class or series of class were as follows:

        SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)




F.
        Allocation of Net Income (Loss)


Net realized and unrealized trading profits and losses, interest income and other operating income and expenses, except class or series specific commission charges, are allocated to the partners monthly in proportion to their capital account balance, as defined in the Agreement.  Class and/or series specific commission charges are allocated monthly to the partners of the respective class and/or series in proportion to their respective capital account balances within the class and/or series.



G.
        Incentive Fees


Willowbridge Associates, Inc. (Willowbridge), the Commodity Trading Advisor (CTA) of the Partnership, is entitled to a quarterly incentive fee based on an increase in the adjusted net asset value of the Partnerships assets allocated to trading.  The CTA receives 25% of any new profits, as defined in the Agreement.  The term new profits is defined as the increase, if any, in the adjusted net asset value of the assets allocated to trading.  No incentive fees were earned during the three months ended March 31, 2007 and 2006.



H.
        Management Fees


The General Partner is paid an annual management fee equal to one percent of the net assets of the Partnership (as defined in the Agreement) as of the last day of the previous fiscal year.  Such annual fee is paid in advance at the beginning of the respective year and is amortized by the Partnership on a straight-line basis over twelve months.  The total management fee paid to the General Partner in 2007 and 2006 was $580,439 and $525,299, respectively.  For the three-month period ended March 31, 2007 and 2006, the Partnership recorded management fee expense earned by the General Partner of $145,110 and $131,105, respectively.  As of March 31, 2007 and December 31, 2006, the unamortized prepaid management fees were $435,329 and $0, respectively.



In addition to the management fee paid to the General Partner, the Partnership pays Willowbridge a quarterly management fee of 0.25% (1% per year) of the net asset value of the Partnership.  These fees amounted to $139,821 and $128,452 for the three months ended March 31, 2007 and 2006, respectively. As of March 31, 2007 and December 31, 2006, $139,821 and $146,529, respectively, were due to Willowbridge.



I.
        Administrative Expenses


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



J.
        Income Taxes


No provision for income taxes has been provided in the accompanying financial statements as each partner is individually liable for taxes, if any, on his or her share of the Partnerships profits.



K.
        Subscriptions


Partnership units may be purchased on the first day of each month at the net asset value per unit determined on the last business day of the previous month.  Partners contributions received in advance for subscriptions are recorded as prepaid subscriptions in the Condensed Statements of Financial Condition. The General Partner charges a one percent initial administrative fee on all limited partner unit subscriptions.  The General Partner may waive this charge for limited partners who are its affiliates or for other limited partners in its sole discretion.  Subscription proceeds to the Partnership are recorded net of these charges.  For the three months ended March 31, 2007 and 2006, the General Partner received initial administrative fees of $1,653 and $8,336, respectively.

        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 expenses such as professional fees.  Actual results could differ from these estimates.



N.
        Recently Issued Accounting Pronouncements


In September 2006, the FASB issued Statement of Financial Accounting Standards No. 157, Fair Value Measurements (FAS 157).  FAS 157 defines fair value, establishes a framework for measuring fair value in generally accepted accounting principles, and expands disclosures about fair value measurements. While FAS 157 does not require any new fair value measurements, for some entities, the application of FAS 157 may change current practice.  FAS 157 is effective for financial statements issued for fiscal years beginning after November 15, 2007, and interim periods within those fiscal years.  The implementation of FAS 157 is not expected to have a material impact on the Partnerships financial statements.



In June 2006, the FASB issued Interpretation No. 48 (FIN 48)
entitled Accounting for Uncertainty in Income Taxes - an interpretation of FASB
Statement No. 109.  FIN 48 prescribes the minimum recognition threshold a
tax position must meet in connection with accounting for uncertainties in income
tax positions taken or expected to be taken by an entity before being measured
and recognized in the financial statements.  Adoption of FIN 48 is required
for fiscal years beginning after December 15, 2006.  The Partnership has
evaluated its tax positions and has determined that the implementation of this
pronouncement does not have a material impact on the Partnerships financial
statements.



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
Partnership has evaluated its financial instruments and has determined that the
implementation of this pronouncement does not 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.

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

General

RFMC Willowbridge Fund, L.P. (formerly named 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
subscriptions 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% annually of the net asset value of the Class B partners' capital. The General Partner will pay up to 3.0% from this amount to properly registered selling agents as their compensation, and to the extent the amount is less than 3.0% 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.

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 Income (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 March 31, 2007 and 2006

For the quarter ended March 31, 2007, the partnership had total losses comprised of net trading losses representing $(3,033,383) in realized losses on closed positions, and $(643,345) in change in net unrealized losses on open positions, and $659,769 in interest income.

subscriptions and redemptions. Administrative expenses consists primary of professional fees and other expenses relating to the Partnership's reporting requirements under Securities Exchange Act of 1934, as amended.

As a result of above, the Partnership recorded a net loss of $4,119,902 for the quarter compared to a net loss of $2,763,936 for the same quarter in 2006.

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 is required to contribute $1,000 to 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 the 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 March 31, 2007, 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 March 31, 2007, 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
March 31, 2007 market rates and prices on its instruments to



13








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:




        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 March 31, 2007.The potential loss in earnings for each market risk exposure as of March 31, 2007 was approximately:

Item 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 March 31, 2007 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 first quarter of 2007.

Units), if any, will be made to partners. The Partnership has never paid any
distributions and does not anticipate paying any distributions to partners in
the foreseeable future. From January 1, 2007 through March 31, 2007, a total
