1. ORGANIZATION OF THE PARTNERSHIP

      Nestor Partners (the "Partnership") is a limited partnership, which was
      organized in 1976 under the New Jersey Uniform Limited Partnership Act.
      The Limited Partnership Agreement (the "Agreement") was amended and
      restated as of April 5, 2004. The Partnership engages in the speculative
      trading of futures and forward currency contracts. The instruments that
      are traded by the Partnership are volatile and involve a high degree of
      market risk.

      The General Partner of the Partnership is Millburn Ridgefield Corporation
      (the "General Partner"). Principals, employees, former employees, and
      other affiliates of the General Partner have invested in the Partnership
      as special limited partners.

      The Agreement provides that subject to certain limitations, the General
      Partner shall conduct and manage the business of the Partnership. The
      General Partner has the right to make all investment decisions regarding
      the Partnership, authorize the payments of distributions to partners,
      enter into customer agreements with brokers, and take such other actions,
      as it deems necessary or desirable, to manage the business of the
      Partnership.

      The limited partners, special limited partners, New Profit Memo Account,
      and the General Partner share in the profits and losses of the
      Partnership, which are determined before brokerage fees (Note 2) and
      profit share allocations on the basis of their proportionate interests of
      Partnership capital (Note 3). THE GENERAL PARTNER AND SPECIAL LIMITED
      PARTNERS ARE CHARGED LOWER BROKERAGE FEES THAN LIMITED PARTNERS, WHICH IN
      2004 AND 2003 RESULTED IN THE GENERAL PARTNER AND SPECIAL LIMITED PARTNERS
      EXPERIENCING NET GAINS AND THE LIMITED PARTNERS, IN AGGREGATE, NET LOSSES.
      No limited partner or special limited partner shall be liable for
      Partnership obligations in excess of their capital contribution plus
      profits allocated to their capital accounts, if any.

      Subject to certain conditions, a partner HAS THE RIGHT TO REDEEM ALL OR A
      PORTION OF ITS PARTNERSHIP CAPITAL AS OF ANY MONTH-END UPON FIFTEEN DAYS'
      PRIOR WRITTEN NOTICE TO THE GENERAL PARTNER. IN ITS SOLE DISCRETION, THE
      GENERAL PARTNER MAY PERMIT REDEMPTIONS ON SHORTER NOTICE OR AS OF A DATE
      OTHER THAN MONTH-END. PARTNERS WHO PURCHASED THEIR INTERESTS THROUGH
      CERTAIN SELLING AGENTS AND REDEEM THEIR PARTNERSHIP CAPITAL PRIOR TO THE
      ONE-YEAR ANNIVERSARY OF THEIR SUBSCRIPTION WILL PAY THE APPLICABLE EARLY
      REDEMPTION FEE. REDEMPTIONS WILL BE MADE AS OF THE LAST DAY OF THE MONTH
      FOR AN AMOUNT EQUAL TO THE NET ASSET VALUE OF THE PORTION OF A PARTNER'S
      CAPITAL BEING REDEEMED; A REDEEMING PARTNER SHALL RECEIVE SUCH REDEEMED
      CAPITAL LESS THE REDEMPTION FEE, IF ANY.

      The General Partner, subject to Commodity Futures Trading Commission
      requirements, may (at its discretion) sell additional Limited Partnership
      Interests to persons desiring to become limited partners.

      The Partnership will terminate on October 31, 2017, or in the event of
      certain other circumstances, as defined in the Agreement.

      At December 31, 2003, the number of partners in the Partnership exceeded
      500. As a result, pursuant to the requirements of Section 12(g) of the
      Securities Exchange Act of 1934 (the "Act"), the Partnership filed a
      registration statement on Form 10 with the Securities and Exchange
      Commission on April 29, 2004, and became subject to the periodic reporting
      requirements of the Act.

3. PROFIT SHARE ALLOCATION

      The Agreement provides that the General Partner's profit share equal to
      20% of Trading Profits (as defined in the Agreement) at the end of each
      year is charged to the limited partners' capital accounts. However, for
      limited partners' withdrawals during the year, the profit share
      calculation shall be computed as though the withdrawal date was at year
      end. BECAUSE LIMITED PARTNERS MAY PURCHASE THEIR PARTNERSHIP INTERESTS AT
      DIFFERENT TIMES, THEY MAY RECOGNIZE DIFFERENT AMOUNTS OF TRADING PROFITS.
      EACH LIMITED PARTNER PAYS A PROFIT SHARE ONLY ON TRADING PROFITS
      APPLICABLE TO ITS PARTNERSHIP INTEREST. LIMITED PARTNERS WHO MAKE MULTIPLE
      INVESTMENTS IN THE PARTNERSHIP RECEIVE SEPARATE PARTNERSHIP INTERESTS FOR
      PURPOSES OF TRACKING THE PROFIT SHARE. ACCORDINGLY, IN ANY GIVEN YEAR,
      SOME LIMITED PARTNERS MAY EXPERIENCE NET GAINS AND BE CHARGED THE 20%
      PROFIT SHARE ALLOCATION FOR ALL OR A PORTION OF THEIR INTERESTS WHERE
      LIMITED PARTNERS IN THE AGGREGATE EXPERIENCED NET LOSSES.

      Any profit share charged is added to the General Partner's capital account
      to the extent net taxable capital gains are allocated to the General
      Partner, and the remainder, if any, of such profit share is added to the
      New Profit Memo Account. The General Partner may not make any withdrawal
      from the balance in the New Profit Memo Account. If, at the end of a
      subsequent year, net taxable gains are allocated to the General Partner in
      excess of such year's profit share, a corresponding amount is transferred
      from the New Profit memo account to the General Partner's capital account.
