EXHIBIT 10.9(a)

AMENDED AND RESTATED MANAGEMENT AGREEMENT

This AMENDED AND RESTATED MANAGEMENT AGREEMENT made effective as of the 1st day of March, 2012 among CERES MANAGED FUTURES LLC, a Delaware limited liability company (“CMF” or the “General Partner”), EMERGING CTA PORTFOLIO L.P., a New York limited partnership (the “Partnership”) and WILLOWBRIDGE ASSOCIATES INC., a Delaware corporation (“Willowbridge” or the “Advisor,” together with the General Partner and the Partnership, the “Parties”). This agreement amends and restates the Management Agreement dated as of May 31, 2011 (the “Existing Agreement”) by and among the Parties.

W I T N E S S E T H :

WHEREAS, CMF is the general partner of the Partnership, a limited partnership organized for the purpose of speculative trading of commodity interests, including futures contracts, options, forward contracts, swaps and other derivative instruments with the objective of achieving substantial capital appreciation; and

WHEREAS, the Amended and Restated Limited Partnership Agreement dated as of October 20, 2010 (the “Partnership Agreement”), permits CMF to delegate to one or more commodity trading advisors CMF’s authority to make trading decisions for the Partnership, which advisors may or may not have any prior experience managing client funds; and

WHEREAS, the Advisor is registered as a commodity trading advisor with the Commodity Futures Trading Commission (“CFTC”) and is a member of the National Futures Association (“NFA”); and

WHEREAS, CMF is registered as a commodity pool operator with the CFTC and is a member of the NFA; and

WHEREAS, the Parties have entered into the Existing Agreement and now wish to amend and restate the Existing Agreement to (i) select the Advisor’s wPraxis Futures Trading Approach to manage the portion of the Partnership’s assets that are allocated to Willowbridge, (ii) to increase the amount of leverage used to manage the Partnership’s assets and (iii) to make other miscellaneous changes to this Agreement; and

WHEREAS, CMF, the Partnership and the Advisor wish to enter into this Agreement in order to set forth the terms and conditions upon which the Advisor will render and implement advisory services in connection with the conduct by the Partnership of its commodity trading activities during the term of this Agreement;

NOW, THEREFORE, the parties agree as follows:

1. DUTIES OF THE ADVISOR. (a) For the period and on the terms and conditions of this Agreement, the Advisor shall have sole authority and responsibility, as one of the Partnership’s agents and attorneys-in-fact, for directing the investment and reinvestment of the assets and funds of the Partnership allocated to it by the General Partner in commodity interests, including commodity futures contracts, options, forward contracts, swaps and other

derivative instruments. All such trading on behalf of the Partnership shall be in accordance with the trading policies set forth in the Partnership’s Private Placement Memorandum dated September 2011, as supplemented (the “Memorandum”), as such trading policies may be changed from time to time upon receipt by the Advisor of prior written notice of such change, and pursuant to the trading strategy selected by CMF to be utilized by the Advisor in managing the Partnership’s assets. CMF has initially selected the Advisor’s wPraxis Futures Trading Approach (the “Program”) to manage the Partnership’s assets allocated to it, and CMF and the Partnership agree that the Advisor will manage the assets of the Partnership utilizing 2 times the leverage normally applied to the Program, unless otherwise agreed to by the parties hereto in writing. Any open positions or other investments at the time of receipt of such notice of a change in trading policy shall not be deemed to violate the changed policy and shall be closed or sold in the ordinary course of trading. The Advisor may not deviate from the trading policies set forth in the Memorandum without the prior written consent of the Partnership given by CMF. The Advisor makes no representation or warranty that the trading to be directed by it for the Partnership will be profitable or will not incur losses.

(b) CMF acknowledges receipt of the Advisor’s Disclosure Document dated May 23, 2011 as filed with the NFA (the “Disclosure Document”). All trades made by the Advisor for the account of the Partnership shall be made through such commodity broker or brokers as CMF shall direct, and the Advisor shall have no authority or responsibility for selecting or supervising any such broker in connection with the execution, clearance or confirmation of transactions for the Partnership or for the negotiation of brokerage rates charged therefore. However, the Advisor, with the prior written permission (by original, fax copy or email copy) of CMF, may direct all trades in commodity futures and options to a futures commission merchant or independent floor broker it chooses for execution with instructions to give-up the trades to the broker designated by CMF, provided that the futures commission merchant or independent floor broker and any give-up or floor brokerage fees are approved in advance by CMF. All give-up or similar fees relating to the foregoing shall be paid by the Partnership after all parties have executed the relevant give-up agreements (by original, fax copy or email copy) and the Advisor shall have no responsibility for such payment. CMF will cause the Partnership’s commodity brokers to provide the Advisor with copies of all confirmation, purchase and sale, monthly and similar statements at the time such statements are available to CMF.

(c) The initial allocation of the Partnership’s assets to the Advisor will be made to the Advisor’s Program, as described in the attached Appendix A attached hereto, provided that CMF and the Partnership agree that the Advisor will manage the assets of the Partnership utilizing 2 times the leverage normally applied to the Program, unless otherwise agreed to by the parties hereto in writing. In the event the Advisor wishes to use a trading system or methodology other than or in addition to the Program in connection with its trading for the Partnership, either in whole or in part, or wishes to change the amount of leverage applied to the Program, it may not do so unless the Advisor gives CMF prior written notice of its intention to utilize such different trading system or methodology and CMF consents thereto in writing. In addition, the Advisor will provide five days’ prior written notice to CMF of any change in the trading system or methodology to be utilized for the Partnership which the Advisor deems material. If the Advisor deems such change in system or methodology or in markets traded to be material, the changed system or methodology or markets traded will not be utilized for the

- 2 -

Partnership without the prior written consent of CMF. In addition, the Advisor will notify CMF of any changes to the trading system or methodology that would require a change in the description of the trading strategy or methods described in the Disclosure Document to be materially inaccurate. Non-material changes in the trading systems utilized on behalf of the Partnership may be instituted without prior written approval. Further, the Advisor will provide the Partnership with a current list of all commodity interests to be traded for the Partnership’s account and the Advisor will not trade any additional commodity interests for such account without providing notice thereof to CMF and receiving CMF’s written approval. The Advisor also agrees to provide CMF, on a monthly basis, with a written report of the assets under the Advisor’s management together with all other matters deemed by the Advisor to be material changes to its business not previously reported to CMF. The Advisor further agrees that it will convert foreign currency balances (not required to margin positions denominated in a foreign currency) to U.S. dollars no less frequently than monthly. U.S. dollar equivalents in individual foreign currencies of more than $100,000 will be converted to U.S. dollars within one business day after such funds are no longer needed to margin foreign positions. The parties acknowledge that if Net Assets (as defined in Section 3(b) hereof) of the Partnership under the Advisor’s management fall below $750,000 the Advisor may not be able to trade the Program in full.

(d) The Advisor agrees to make all material disclosures to the Partnership regarding itself and its principals as defined in Part 4 of the CFTC’s regulations (“principals”), shareholders, directors, officers and employees, their trading performance and general trading methods, its customer accounts (but not the identities of or identifying information with respect to its customers or other information deemed by the Advisor to be proprietary and confidential) and otherwise as are required in the reasonable judgment of CMF to be made in any filings required by federal or state law or NFA rule or order. Notwithstanding Sections 1(d) and 4(d) of this Agreement, the Advisor shall not be required to disclose the actual trading results of proprietary accounts of the Advisor or its principals unless CMF reasonably determines that such disclosure is required in order to fulfill its fiduciary obligations to the Partnership or the reporting, filing or other obligations imposed on it by federal or state law or NFA rule or order. The Partnership and CMF acknowledge that the trading advice to be provided by the Advisor is a property right belonging to the Advisor and that they will keep all such advice confidential. Neither CMF nor the Partnership shall distribute, except to officers, directors, employees, partners or affiliates of CMF or the Partnership, any description of the Advisor, its principals, or its or their trading performance without the prior written consent of the Advisor, which consent shall not be unreasonably withheld.

(e) The Advisor understands and agrees that CMF may designate other trading advisors for the Partnership and apportion or reapportion to such other trading advisors the management of an amount of Net Assets as it shall determine in its absolute discretion. The designation of other trading advisors and the apportionment or reapportionment of Net Assets to any such trading advisors pursuant to this Section 1 shall neither terminate this Agreement nor modify in any regard the respective rights and obligations of the parties hereunder.

(f) CMF may, from time to time, in its absolute discretion, select additional trading advisors and reapportion funds among the trading advisors for the Partnership as it deems appropriate. CMF shall use its best efforts to make reapportionments, if any, as of the first day of a month. The Advisor agrees that it may be called upon at any time promptly to liquidate

- 3 -

positions in CMF’s sole discretion so that CMF may reallocate the Partnership’s assets, meet margin calls on the Partnership’s account, fund redemptions, or for any other reason, except that CMF will not require the liquidation of specific positions by the Advisor. CMF will use its best efforts to give two days’ prior notice to the Advisor of any reallocations or liquidations.

(g) The Advisor will not be liable for trading losses in the Partnership’s account including losses caused by errors; provided, however, that (i) the Advisor will be liable to the Partnership with respect to losses incurred due to errors committed or caused by it or any of its principals or employees in communicating improper trading instructions or orders to any broker on behalf of the Partnership and (ii) the Advisor will be liable to the Partnership with respect to losses incurred due to errors committed or caused by any executing broker (other than any CMF affiliate) selected by the Advisor, it being understood that CMF, with the assistance of the Advisor, will first attempt to recover such losses from the executing broker.

2. INDEPENDENCE OF THE ADVISOR. For all purposes herein, the Advisor shall be deemed to be an independent contractor and, unless otherwise expressly provided or authorized, shall have no authority to act for or represent the Partnership in any way and shall not be deemed an agent, promoter or sponsor of the Partnership, CMF, or any other trading advisor. The Advisor shall not be responsible to the Partnership, the General Partner, any trading advisor or any limited partners for any acts or omissions of any other trading advisor to the Partnership.

3. COMPENSATION. (a) In consideration of and as compensation for all of the services to be rendered by the Advisor to the Partnership under this Agreement, the Partnership shall pay the Advisor (i) an incentive fee payable quarterly equal to 20% of New Trading Profits (as such term is defined below) earned by the Advisor for the Partnership and (ii) a monthly fee for professional management services equal to 1% per year of the month-end Net Assets of the Partnership allocated to the Advisor (computed monthly by multiplying the adjusted net assets of the Fund allocated to the Advisor as of the last business day of each month by 1% and dividing the result thereof by 12).

(b) “Net Assets” shall have the meaning set forth in Section 7(d)(1) of the Partnership Agreement and without regard to further amendments thereto, provided that in determining the Net Assets of the Partnership on any date, no adjustment shall be made to reflect any distributions, redemptions or incentive fees payable as of the date of such determination.

(c) “New Trading Profits” shall mean the excess, if any, of Net Assets managed by the Advisor at the end of the quarter over Net Assets managed by the Advisor at the end of the highest previous quarter or Net Assets allocated to the Advisor at the date trading commences, whichever is higher, and as further adjusted to eliminate the effect on Net Assets resulting from new capital contributions, redemptions, reallocations or capital distributions, if any, made during the fiscal quarter decreased by interest or other income, not directly related to trading activity, earned on the Partnership’s assets during the fiscal quarter, whether the assets are held separately or in margin accounts. Ongoing expenses shall be attributed to the Advisor based on the Advisor’s proportionate share of Net Assets. Ongoing expenses will not include expenses of litigation not involving the activities of the Advisor on behalf of the Partnership. Interest income earned, if any, will not be taken into account in computing New Trading Profits

- 4 -

earned by the Advisor. If Net Assets allocated to the Advisor are reduced due to redemptions, distributions or reallocations (net of additions), there will be a corresponding proportional reduction in the related loss carryforward amount that must be recouped before the Advisor is eligible to receive another incentive fee.

(d) Quarterly incentive fees and monthly management fees shall be paid within twenty (20) business days following the end of the period for which such fee is payable. In the event of the termination of this Agreement as of any date which shall not be the end of a calendar quarter or a calendar month, as the case may be, the quarterly incentive fee shall be computed as if the effective date of termination were the last day of the then current quarter and the monthly management fee shall be prorated to the effective date of termination. If, during any month, the Partnership does not conduct business operations or the Advisor is unable to provide the services contemplated herein for more than two successive business days, the monthly management fee shall be prorated by the ratio which the number of business days during which CMF conducted the Partnership’s business operations or utilized the Advisor’s services bears in the month to the total number of business days in such month. No incentive fee shall be paid to the Advisor until the end of the first calendar quarter of the Advisor’s trading for the Partnership, which incentive fee shall be based on New Trading Profits, if any, earned from the commencement of trading by the Advisor on behalf of the Partnership through the end of the first calendar quarter of such trading.

(e) The provisions of this Section 3 shall survive the termination of this Agreement.

4. RIGHT TO ENGAGE IN OTHER ACTIVITIES. (a) Except as otherwise provided herein, the services provided by the Advisor hereunder are not to be deemed exclusive. CMF on its own behalf and on behalf of the Partnership acknowledges that, subject to the terms of this Agreement, the Advisor and its officers, directors, employees and shareholder(s), may render advisory, consulting and management services to other clients and accounts. The Advisor and its officers, directors, employees and shareholder(s) shall be free to trade for their own accounts and to advise other investors and manage other commodity accounts during the term of this Agreement and to use the same information, computer programs and trading strategies, programs or formulas which they obtain, produce or utilize in the performance of services to CMF for the Partnership. However, the Advisor represents, warrants and agrees that it believes the rendering of such consulting, advisory and management services to other accounts and entities will not require any material change in the Advisor’s Program and will not affect the capacity of the Advisor to continue to render services to CMF for the Partnership of the quality and nature contemplated by this Agreement.

(b) If, at any time during the term of this Agreement, the Advisor is required to aggregate the Partnership’s commodity positions with the positions of any other person for purposes of applying CFTC- or exchange-imposed speculative position limits, the Advisor agrees that it will promptly notify CMF in writing if the Partnership’s positions are included in an aggregate amount which exceeds the applicable speculative position limit. The Advisor agrees that, if its trading recommendations are altered because of the application of any speculative position limits, it will not modify the trading instructions with respect to the Partnership’s account in such manner as to affect the Partnership substantially disproportionately

- 5 -

as compared with the Advisor’s other accounts. The Advisor further represents, warrants and agrees that under no circumstances will it knowingly or deliberately use trading programs, strategies or methods for the Partnership that are inferior to strategies or methods employed for any other client or account whose assets are traded pursuant to the Program and that it will not knowingly or deliberately favor any client or account managed by it over any other client or account whose assets are traded pursuant to the Program in any manner, it being acknowledged, however, that different trading programs, strategies or methods may be utilized for differing sizes of accounts, accounts traded with different degrees of leverage accounts with different trading policies, accounts experiencing differing inflows or outflows of equity, accounts that commence trading at different times, accounts that have different portfolios or different fiscal years, accounts utilizing different executing brokers and accounts with other differences, and that such differences may cause divergent trading results.

(c) It is acknowledged that the Advisor and/or its officers, employees, directors and shareholder(s) presently act, and it is agreed that they may continue to act, as advisor for other accounts managed by them, and may continue to receive compensation with respect to services for such accounts in amounts which may be more or less than the amounts received from the Partnership.

(d) The Advisor agrees that it shall make such information available to CMF respecting the performance of the Partnership’s account as compared to the performance of other accounts managed by the Advisor or its principals, if any, as shall be reasonably requested by CMF, provided that nothing contained herein shall be deemed to require the Advisor to disclose the names of other customers or information that the Advisor deems to be proprietary or confidential. The Advisor presently believes and represents that existing speculative position limits will not materially adversely affect its ability to manage the Partnership’s account given the potential size of the Partnership’s account and the Advisor’s and its principals’ current accounts and all proposed accounts for which they have contracted to act as trading advisor.

5. TERM. (a) This Agreement shall continue in effect until June 30, 2012. CMF may, in its sole discretion, renew this Agreement for additional one-year periods upon notice to the Advisor not less than 30 days prior to the expiration of the previous period. After June 30, 2012, CMF may terminate this Agreement at any month-end upon 30 days’ notice to the Advisor. At any time during the term of this Agreement, CMF may elect to immediately terminate this Agreement upon 5 days’ notice to the Advisor if (i) the Net Asset Value per Unit shall decline as of the close of business on any day to $400 or less; (ii) the Net Assets allocated to the Advisor (adjusted for redemptions, distributions, withdrawals or reallocations, if any) decline by 20% or more as of the end of a trading day from such Net Assets’ previous highest value; (iii) limited partners owning at least 50% of the outstanding units of the Partnership shall vote to require CMF to terminate this Agreement; (iv) the Advisor fails to comply with the terms of this Agreement; (v) CMF, in good faith, reasonably determines that the performance of the Advisor has been such that CMF’s fiduciary duties to the Partnership require CMF to terminate this Agreement; (vi) CMF reasonably believes that the application of speculative position limits will substantially affect the performance of the Partnership; or (vii) the Advisor fails to conform to the trading policies set forth in the Memorandum as they may be changed from time to time and delivered in writing to the Advisor. At any time during the term of this Agreement, CMF may elect immediately to terminate this Agreement if (i) the Advisor merges, consolidates with

- 6 -

another entity, sells a substantial portion of its assets, or becomes bankrupt or insolvent, (ii) Philip Yang and Frank Marrapodi both die, become incapacitated, leave the employ of the Advisor, cease to control the Advisor or are otherwise not managing the trading programs or systems of the Advisor, (iii) the Advisor’s registration as a commodity trading advisor with the CFTC or its membership in the NFA or any other regulatory authority, is terminated or suspended; or (iv) CMF reasonably believes that the Advisor has or may contribute to any material operational, business, or reputational risk to CMF or CMF’s affiliates. This Agreement will immediately terminate upon dissolution of the Partnership or upon cessation of trading prior to dissolution.

(b) The Advisor may terminate this Agreement by giving not less than 30 days’ notice to CMF (i) in the event that the trading policies of the Partnership as set forth in the Memorandum are changed in such manner that the Advisor reasonably believes will adversely affect the performance of its trading strategies; (ii) after June 30, 2012; or (iii) in the event that the General Partner or Partnership fails to comply with the terms of this Agreement. The Advisor may immediately terminate this Agreement if (i) Net Assets of the Partnership under the Advisor’s management falls below $750,000; or (ii) CMF’s registration as a commodity pool operator or its membership in the NFA is terminated or suspended.

(c) Except as otherwise provided in this Agreement, any termination of this Agreement in accordance with this Section 5 shall be without penalty or liability to any party, except for any fees due to the Advisor pursuant to Section 3 hereof.

6. INDEMNIFICATION. (a)(i) In any threatened, pending or completed action, suit, or proceeding to which the Advisor was or is a party or is threatened to be made a party arising out of or in connection with this Agreement or the management of the Partnership’s assets by the Advisor or the offering and sale of units in the Partnership, CMF shall, subject to subsection (a)(iii) of this Section 6, indemnify and hold harmless the Advisor against any loss, liability, damage, fine, penalty, obligation, cost, expense (including, without limitation, attorneys’ and accountants’ fees, collection fees, court costs and other legal expenses), judgments and awards and amounts paid in settlement actually and reasonably incurred by it in connection with such action, suit, or proceeding if the Advisor acted in good faith and in a manner reasonably believed to be in or not opposed to the best interests of the Partnership, and provided that its conduct did not constitute negligence, bad faith, intentional misconduct, or a breach of its fiduciary obligations to the Partnership as a commodity trading advisor, unless and only to the extent that the court or administrative forum in which such action or suit was brought shall determine upon application that, despite the adjudication of liability but in view of all circumstances of the case, the Advisor is fairly and reasonably entitled to indemnity for such expenses which such court or administrative forum shall deem proper; and further provided that no indemnification shall be available from the Partnership if such indemnification is prohibited by Section 16 of the Partnership Agreement. The termination of any action, suit or proceeding by judgment, order or settlement shall not, of itself, create a presumption that the Advisor did not act in good faith and in a manner reasonably believed to be in or not opposed to the best interests of the Partnership.

- 7 -

(ii) Without limiting subsection (i) above, to the extent that the Advisor has been successful on the merits or otherwise in defense of any action, suit or proceeding referred to in subsection (i) above, or in defense of any claim, issue or matter therein, CMF shall indemnify the Advisor against the expenses (including, without limitation, attorneys’ and accountants’ fees) actually and reasonably incurred by it in connection therewith.

(iii) Any indemnification under subsection (i) above, unless ordered by a court, arbitrator or administrative forum, shall be made by CMF only as authorized in the specific case and only upon a determination by independent legal counsel in a written opinion that such indemnification is proper in the circumstances because the Advisor has met the applicable standard of conduct set forth in subsection (i) above. Such independent legal counsel shall be selected by CMF in a timely manner, subject to the Advisor’s approval, which approval shall not be unreasonably withheld. The Advisor will be deemed to have approved CMF’s selection unless the Advisor notifies CMF in writing, received by CMF within five days of CMF’s telecopying to the Advisor of the notice of CMF’s selection, that the Advisor does not approve the selection.

(iv) In the event the Advisor is made a party to any claim, dispute or litigation or otherwise incurs any loss or expense as a result of, or in connection with, the Partnership’s or CMF’s activities or claimed activities unrelated to the Advisor, CMF shall indemnify, defend and hold harmless the Advisor against any loss, liability, damage, cost or expense (including, without limitation, attorneys’ and accountants’ fees) incurred in connection therewith.

(v) As used in this Section 6(a), the term “Advisor” shall include the Advisor, its principals, officers, directors, stockholders and employees and the term “CMF” shall include the Partnership.

(b) (i) The Advisor agrees to indemnify, defend and hold harmless CMF, the Partnership and their affiliates against any loss, liability, damage, fine, penalty, obligation, cost or expense (including, without limitation, attorneys’ and accountants’ fees, collection fees, court costs and other legal expenses), judgments and awards and amounts paid in settlement reasonably incurred by them (A) as a result of the breach of any representations and warranties or covenants made by the Advisor in this Agreement, or (B) as a result of any act or omission of the Advisor relating to the Partnership if (i) there has been a final judicial or regulatory determination, a written opinion of an arbitrator pursuant to Section 14 hereof, to the effect that such acts or omissions violated the terms of this Agreement in any material respect or involved negligence, bad faith or intentional misconduct on the part of the Advisor (except as otherwise provided in Section 1(g)), or (ii) there has been a settlement of any action or proceeding with the Advisor’s prior written consent.

(ii) In the event CMF, the Partnership or any of their affiliates is made a party to any claim, dispute or litigation or otherwise incurs any loss or expense as a result of, or in connection with, the activities or claimed activities of the Advisor or its principals, officers, directors, shareholder(s) or employees unrelated to CMF’s or the Partnership’s business, the Advisor shall indemnify, defend and hold harmless CMF, the Partnership or any of their affiliates against any loss, liability, damage, fine, penalty obligation, cost or expense (including, without limitation, attorneys’ and accountants’ fees, collection fees, court costs and other legal expenses), judgments, awards and amounts including amounts paid in settlement incurred in connection therewith.

- 8 -

(iii) Neither Philip Yang nor Frank Marrapodi shall have any liability to the Partnership or CMF or any of their respective officers, directors, employees, partners or affiliates under this Agreement or in connection with the transactions contemplated by this Agreement except in the case of his own fraud or willful misconduct.

(iv) Any indemnification under subsection (b)(i) above, unless ordered by a court, arbitrator or administrative forum, shall be made by the Advisor only as authorized in the specific case and only upon a determination by independent legal counsel in a written opinion that such indemnification is proper in the circumstances. Such independent legal counsel shall be selected by the Advisor in a timely manner, subject to CMF’s approval, which approval shall not be unreasonably withheld. CMF will be deemed to have approved the Advisor’s selection unless CMF notifies the Advisor in writing, received by the Advisor within five days of the Advisor’s facsimile to CMF of the notice of the Advisor’s selection, that CMF does not approve the selection.

(c) In the event that a person entitled to indemnification under this Section 6 is made a party to an action, suit or proceeding alleging both matters for which indemnification can be made hereunder and matters for which indemnification may not be made hereunder, such person shall be indemnified only for that portion of the loss, liability, damage, cost or expense incurred in such action, suit or proceeding which relates to the matters for which indemnification can be made.

(d) None of the indemnifications contained in this Section 6 shall be applicable with respect to default judgments, confessions of judgment or settlements entered into by the party claiming indemnification without the prior written consent, which shall not be unreasonably withheld, of the party obligated to indemnify such party.

(e) The provisions of this Section 6 shall survive the termination of this Agreement.

APPENDIX A

The wPraxis Futures Trading Approach

The wPraxis Futures Trading Approach’s primary investment objective is to achieve capital appreciation from trading. Willowbridge will utilize a fully discretionary trading strategy to build a portfolio consisting of futures on currency, fixed income, stock indices and commodities pursuant to its wPraxis approach. The approach may trade commodities, futures, forwards, options, spot contracts in the commodities, currencies, and fixed income markets, and, in the future, it may trade swaps.

Trading decisions are made jointly by Philip Yang and by Frank Marrapodi, a trader for Willowbridge. Both Mr. Yang and Mr. Marrapodi must agree on each position taken in the program. They utilize their experience in the markets and their analysis of fundamental and technical information to formulate reward to risk expectations about a broad number of liquid markets. All positions are closely monitored to evaluate risk parameter status. As markets move, positions are refined and expectations updated in response to current market conditions.
