The Trustee aggregates certain of these adjustments and makes conforming changes to the Portfolio at least monthly. The Trustee directs its stock transactions only to brokers or dealers, which may include affiliates of the Trustee, from whom it expects to obtain the most favorable prices or execution of orders. Adjustments are made more frequently in the case of significant changes to the DJIA. Specifically, the Trustee is required to adjust the composition of the Portfolio whenever there is a change in the identity of any Index Security (i.e., a substitution of one security for another) within three (3) Business Days before or after the day on which the change is scheduled to take effect. While other DJIA changes may lead to adjustments in the Portfolio, the most common changes are likely to occur as a result of changes in the Index Securities included in the DJIA and as a result of stock splits. The Trust Agreement sets forth the method of adjustments which may occur thereunder as a result of corporate actions to the DJIA, such as stock splits or changes in the identity of the component stocks.

For example, in the event of an Index Security change (in which the common stock of one issuer held in the DJIA is replaced by the common stock of another), the Trustee may sell all shares of the Portfolio Security corresponding to the old Index Security and use the proceeds of such sale to purchase the replacement Portfolio Security corresponding to the new Index Security. If the share price of the removed Portfolio Security was higher than the price of its replacement, the Trustee will calculate how to allocate the proceeds of the sale of the removed Portfolio Security between the purchase of its replacement and purchases of additional shares of other Portfolio Securities so that the number of shares of each Portfolio Security after the transactions would be as nearly equal as practicable. If the share price of the removed Portfolio Security was lower than the price of its replacement, the Trustee will calculate the number of shares of each of the other Portfolio Securities that must be sold in order to purchase enough shares of the replacement Portfolio Security so that the number of shares of each Portfolio Security after the transactions would be as nearly equal as practicable.

In the event of a stock split, the price weighting of the stock which is split will drop. The Trustee may make the corresponding adjustment by selling the additional shares of the Portfolio Security received from the stock split. The Trustee may then use the proceeds of the sale to buy an equal number of shares of each Portfolio Security-including the Portfolio Security which had just experienced a stock split. In practice, of course, not all the shares received in the split would be sold: enough of those shares would be retained to make an increase in the number of split shares equal to the increase in the number of shares in each of the other Portfolio Securities purchased with the proceeds of the sale of the remaining shares resulting from such split.

As a result of the purchase and sale of stock in accordance with these requirements, or the creation of Creation Units, the Trust may hold some amount of residual cash (other than cash held temporarily due to timing

39

differences between the sale and purchase of stock or cash delivered in lieu of Index Securities or undistributed income or undistributed capital gains). This amount may not exceed for more than two (2) consecutive Business Days 5/10th of 1 percent of the value of the Portfolio. If the Trustee has made all required adjustments and is left with cash in excess of 5/10th of 1 percent of the value of the Portfolio, the Trustee will use such cash to purchase additional Index Securities.

All portfolio adjustments are made as described herein unless such adjustments would cause the Trust to lose its status as a "regulated investment company" under Subchapter M of the Code. Additionally, the Trustee is required to adjust the composition of the Portfolio at any time to insure the continued qualification of the Trust as a regulated investment company.

The Trustee relies on Dow Jones for information as to the composition and weightings of Index Securities. If the Trustee becomes incapable of obtaining or processing such information or NSCC is unable to receive such information from the Trustee on any Business Day, the Trustee shall use the composition and weightings of Index Securities for the most recently effective Portfolio Deposit for the purposes of all adjustments and determinations (including, without limitation, determination of the stock portion of the Portfolio Deposit) until the earlier of (a) such time as current information with respect to Index Securities is available or (b) three (3) consecutive Business Days have elapsed. If such current information is not available and three (3) consecutive Business Days have elapsed, the composition and weightings of Portfolio Securities (as opposed to Index Securities) shall be used for the purposes of all adjustments and determinations (including, without limitation, determination of the stock portion of the Portfolio Deposit) until current information with respect to Index Securities is available.

If the Trust is terminated, the Trustee shall use the composition and weightings of Portfolio Securities as of such notice date for the purpose and determination of all redemptions or other required uses of the basket.

From time to time Dow Jones may adjust the composition of the DJIA because of a merger or acquisition involving one or more Index Securities. In such cases, the Trust, as shareholder of an issuer that is the object of such merger or acquisition activity, may receive various offers from would-be acquirors of the issuer. The Trustee is not permitted to accept any such offers until such time as it has been determined that the stocks of the issuer will be removed from the DJIA. As stocks of an issuer are often removed from the DJIA only after the consummation of a merger or acquisition of such issuer, in selling the securities of such issuer the Trust may receive, to the extent that market prices do not provide a more attractive alternative, whatever consideration is being offered to the shareholders of such issuer that have not tendered their shares prior to such time. Any cash received in such transactions is reinvested in Index Securities in accordance with the criteria set forth above.

40

Any stocks received as a part of the consideration that are not Index Securities are sold as soon as practicable and the cash proceeds of such sale are reinvested in accordance with the criteria set forth above.

Adjustments to the Portfolio Deposit

On each Business Day (each such day an "Adjustment Day"), the number of shares and identity of each Index Security in a Portfolio Deposit are adjusted in accordance with the following procedure. At the close of the market the Trustee calculates the NAV of the Trust. The NAV is divided by the number of outstanding DIAMONDS multiplied by 50,000 DIAMONDS in one Creation Unit, resulting in a NAV per Creation Unit ("NAV Amount"). The Trustee then calculates the number of shares (without rounding) of each of the component stocks of the DJIA in a Portfolio Deposit for the following Business Day ("Request Day"), so that (a) the market value at the close of the market on the Adjustment Day of the stocks to be included in the Portfolio Deposit on Request Day, together with the Dividend Equivalent Payment effective for requests to create or redeem on the Adjustment Day, equals the NAV Amount and (b) the identity and weighting of each of the stocks in a Portfolio Deposit mirrors proportionately the identity and weightings of the stocks in the DJIA, each as in effect on Request Day. For each stock, the number resulting from such calculation is rounded down to the nearest whole share. The identities and weightings of the stocks so calculated constitute the stock portion of the Portfolio Deposit effective on Request Day and thereafter until the next subsequent Adjustment Day, as well as Portfolio Securities to be delivered by the Trustee in the event of request for redemption on the Request Day and thereafter until the following Adjustment Day.

In addition to the foregoing adjustments, if a corporate action such as a stock split, stock dividend or reverse split occurs with respect to any Index Security that does not result in an adjustment to the DJIA divisor, the Portfolio Deposit shall be adjusted to take into account the corporate action in each case rounded to the nearest whole share.

On the Request Day and on each day that a request for the creation or redemption is deemed received, the Trustee calculates the market value of the stock portion of the Portfolio Deposit as in effect on the Request Day as of the close of the market and adds to that amount the Dividend Equivalent Payment effective for requests to create or redeem on Request Day (such market value and Dividend Equivalent Payment are collectively referred to herein as "Portfolio Deposit Amount"). The Trustee then calculates the NAV Amount, based on the close of the market on the Request Day. The difference between the NAV Amount so calculated and the Portfolio Deposit Amount is the "Balancing Amount". The Balancing Amount serves the function of compensating for any differences between the value of the Portfolio Deposit Amount and the NAV Amount at the close of trading on Request Day due to, for example, (a) differences in the market value of the securities in the Portfolio

41

---

Deposit and the market value of the Securities on Request Day and (b) any variances from the proper composition of the Portfolio Deposit.

The Dividend Equivalent Payment and the Balancing Amount in effect at the close of business on the Request Date are collectively referred to as the Cash Component or the Cash Redemption Payment. If the Balancing Amount is a positive number (i.e., if the NAV Amount exceeds the Portfolio Deposit Amount) then, with respect to creation, the Balancing Amount increases the Cash Component of the then effective Portfolio Deposit transferred to the Trustee by the creator. With respect to redemptions, the Balancing Amount is added to the cash transferred to the redeemer by the Trustee. If the Balancing Amount is a negative number (i.e., if the NAV Amount is less than the Portfolio Deposit Amount) then, with respect to creation, this amount decreases the Cash Component of the then effective Portfolio Deposit to be transferred to the Trustee by the creator or, if such cash portion is less than the Balancing Amount, the difference must be paid by the Trustee to the creator. With respect to redemptions, the Balancing Amount is deducted from the cash transferred to the redeemer or, if such cash is less than the Balancing Amount, the difference must be paid by the redeemer to the Trustee.

If the Trustee has included the cash equivalent value of one or more Index Securities in the Portfolio Deposit because the Trustee has determined that such Index Securities are likely to be unavailable or available in insufficient quantity for delivery, or if a creator or redeemer is restricted from investing or engaging in transactions in one or more of such Index Securities, the Portfolio Deposit so constituted shall determine the Index Securities to be delivered in connection with the creation of DIAMONDS in Creation Unit size aggregations and upon the redemption of DIAMONDS until the time the stock portion of the Portfolio Deposit is subsequently adjusted.

THE DJIA

The DJIA was first published in 1896. Initially comprised of 12 companies, the DJIA has evolved into the most recognizable stock indicator in the world, and the only index composed of companies that have sustained earnings performance over a significant period of time. In its second century, the DJIA is the oldest continuous barometer of the U.S. stock market, and the most widely quoted indicator of U.S. stock market activity.

The 30 stocks now comprising the DJIA are all leaders in their respective industries, and their stocks are widely held by individuals and institutional investors. These stocks represent more than one-quarter of the $14.4 trillion market value of all US common stocks.

Dow Jones is not responsible for and shall not participate in the creation or sale of DIAMONDS or in the determination of the timing of, prices at, or quantities and proportions in which purchases or sales of Index Securities or Securities shall be made.

Source: Dow Jones Indexes. Year-end index values reflect neither reinvestment of dividends nor costs associated with investing, such as brokerage commissions. Yields are calculated by dividing the sum of the most recent four quarterly per-share dividend payments of all components by the sum of the component prices.

The DJIA is a price-weighted stock index, meaning that the component stocks of the DJIA are accorded relative importance based on their prices. In this regard, the DJIA is unlike many other stock indexes which weight their component stocks by market capitalization (price times shares outstanding). The DJIA is called an "average" because originally it was calculated by adding up the component stock prices and then dividing by the number of stocks. The method remains the same today, but the number of significant digits in the divisor (the number that is divided into the total of the stock prices) has been increased to eight significant digits to minimize distortions due to rounding and has been adjusted over time to insure continuity of the DJIA after component stock changes and corporate actions, as discussed below.

The DJIA divisor is adjusted due to corporate actions that change the price of any of its component shares. The most frequent reason for such an adjustment is a stock split. For example, suppose a company in the DJIA issues one new share for each share outstanding. After this two-for-one "split," each share of stock is worth half what it was immediately before, other things being

45

---

equal. But without an adjustment in the divisor, this split would produce a distortion in the DJIA. An adjustment must be made to compensate so that the "average" will remain unchanged. At Dow Jones, this adjustment is handled by changing the divisor.* The formula used to calculate divisor adjustments is:

New Divisor  =	Current Divisor x Adjusted Sum of Prices
	Unadjusted Sum of Prices

Changes in the composition of the DJIA are made entirely by the editors of The Wall Street Journal without consultation with the companies, the respective stock exchange, or any official agency. Additions or deletions of components may be made to achieve better representation of the broad market and of American industry.

In selecting components for the DJIA, the following criteria are used: (a) the company is not a utility or in the transportation business; (b) the company has a premier reputation in its field; (c) the company has a history of successful growth; and (d) there is wide interest among individual and institutional investors. Whenever one component is changed, the others are reviewed. For the sake of historical continuity, composition changes are made rarely.

The most recent changes in the components of the DJIA were made effective with trading on April 8, 2004.

EXCHANGE LISTING

DIAMONDS are listed on the Exchange. The Trust is not required to pay a listing fee to the Exchange. Transactions involving DIAMONDS in the public trading market are subject to customary brokerage charges and commissions.

The Sponsor's aim in designing DIAMONDS was to provide investors with a security whose initial market value would approximate one-hundredth (1/100th) the value of the DJIA. Of course, the market value of a DIAMONDS unit is affected by a variety of factors, including capital gains distributions made, and expenses incurred, by the Trust, and therefore, over time, a DIAMONDS unit may no longer approximate 1/100th the value of the DJIA. The market price of a DIAMONDS unit should reflect its share of the dividends accumulated on Portfolio Securities and may be affected by supply and demand, market volatility, sentiment and other factors.

There can be no assurance that DIAMONDS will always be listed on the Exchange. The Trust will be terminated if DIAMONDS are delisted. The Exchange will consider the suspension of trading in or removal from listing of DIAMONDS if (a) the Trust has more than 60 days remaining until termination and there are fewer than 50 record and/or beneficial holders of DIAMONDS for 30 or more consecutive trading days; (b) the DJIA is no longer calculated or available; or (c) such other event occurs or condition exists which, in the opinion of the Exchange, makes further dealings on the Exchange inadvisable.

DIAMONDS also are listed and traded on the Singapore Exchange Ltd. ("SGX") pursuant to a joint venture created by the Exchange and the SGX and on Euronext Amsterdam N.V. In the future, DIAMONDS may be listed and traded on other non-U.S. exchanges pursuant to similar arrangements.

TAX STATUS OF THE TRUST

For the fiscal year ended October 31, 2005, the Trust believes that it qualified for tax treatment as a "regulated investment company" under Subchapter M of the Code. The Trust intends to continue to so qualify. To qualify as a regulated investment company, the Trust must, among other things, (a) derive in each taxable year at least 90% of its gross income from dividends, interest, gains from the sale or other disposition of stock, securities or foreign currencies, or certain other sources, (b) meet certain diversification tests, and (c) distribute in each year at least 90% of its investment company taxable income. If the Trust qualifies as a regulated investment company, subject to certain conditions and requirements, the Trust will not be subject to federal income tax to the extent its income is distributed in a timely manner. Any undistributed income may be subject to tax, including a four percent (4%) excise tax imposed by section 4982 of the Code on certain undistributed income of a regulated investment company that does not distribute to shareholders in a timely manner at least ninety-eight percent (98%) of its taxable income (including capital gains).

Income Tax Consequences to Beneficial Owners

Dividends paid by the Trust from its investment company taxable income (which includes dividends, interest and the excess of net short-term capital gains over net long-term capital losses) are generally taxable to Beneficial Owners as ordinary income. However, to the extent that such dividends are designated by the Trust as attributable to the receipt by the Trust of qualified dividend income, such dividends will be eligible for the 15% maximum tax rate applicable to non-corporate taxpayers through 2008. Distributions paid by the Trust from the excess of net long-term capital gains over net short-term capital losses are considered "capital gains dividends" regardless of the length of time an investor has owned DIAMONDS. Any loss on the sale or exchange of a DIAMONDS unit held for six months or less may be treated as a long-term capital loss to the extent of any capital gain dividends received by the Beneficial Owner. For corporate investors, dividends from net investment income (but not return of capital distributions or capital gain dividends) generally qualify for the corporate dividends-received deduction to the extent dividend income received by the Trust so qualifies, subject to the limitations contained in the Code.

A dividend paid in January is considered for federal income tax purposes to have been paid by the Trust and received by Beneficial Owners on the preceding December 31 if the dividend was declared in the preceding October, November or December to Beneficial Owners of record as shown on the records of DTC and the DTC Participants on a date in one of those months. Investors should note that the regular monthly dividends paid by the Trust are not based on the Trust's investment company taxable income and net capital gain, but rather are based on the dividends paid with respect to Portfolio

49

---

Securities. As a result, a portion of the distributions of the Trust may be treated as a return of capital or a capital gain dividend for federal income tax purposes or the Trust may make additional distributions in excess of the yield performance of Portfolio Securities in order to distribute all of its investment company taxable income and net capital gain.

Distributions in excess of the Trust's current or accumulated earnings and profits (as specially computed) generally are treated as a return of capital for federal income tax purposes and reduce a Beneficial Owner's tax basis in DIAMONDS. Return of capital distributions may result, for example, if a portion of the dividends declared represents cash amounts deposited in connection with Portfolio Deposits rather than dividends actually received by the Trust. Under certain circumstances, a significant portion of the Trust's regular monthly dividends could be treated as return of capital distributions. Such circumstances may be more likely to occur in periods during which the number of outstanding DIAMONDS fluctuates significantly. Beneficial Owners receive annually notification from the Trustee through the DTC Participants as to the tax status of the Trust's distributions. A distribution paid shortly after a purchase or creation of DIAMONDS may be taxable even though in effect it may represent a return of capital.

Distributions reinvested in additional DIAMONDS through the means of the Service are nevertheless taxable dividends to Beneficial Owners acquiring such additional DIAMONDS to the same extent as if such dividends were received in cash.

The sale of DIAMONDS by a Beneficial Owner is a taxable event, and may result in a gain or loss, which generally should be a capital gain or loss for Beneficial Owners that are not dealers in securities.

Dividend distributions, capital gains distributions, and capital gains from sales or redemptions may also be subject to state, local and foreign taxes.

Under the Code, an in-kind redemption of DIAMONDS does not result in the recognition of taxable gain or loss by the Trust but generally constitutes a taxable event for the redeeming shareholder. Upon redemption, a Beneficial Owner generally recognizes gain or loss measured by the difference on the date of redemption between the aggregate value of the cash and stocks received and its tax basis in the DIAMONDS redeemed. Stocks received upon redemption (which will be comprised of the stock portion of the Portfolio Deposit in effect on the date of redemption) generally have an initial tax basis equal to their respective market values on the date of redemption. The Internal Revenue Service ("IRS") may assert that any resulting loss may not be deducted by a Beneficial Owner on the basis that there has been no material change in such Beneficial Owner's economic position or that the transaction has no significant economic or business utility apart from the anticipated tax consequences. Beneficial Owners of DIAMONDS in Creation Unit size

50

---

aggregations should consult their own tax advisors as to the consequences to them of the redemption of DIAMONDS.

Deposits of a Portfolio Deposit with the Trustee in exchange for Creation Units do not result in the recognition of taxable gain or loss by the Trust but generally constitute a taxable event to the investor under the Code, and an investor generally recognizes gain or loss with respect to each stock deposited equal to the difference between the amount realized in respect of the stock and the investor's tax basis therein. The amount realized with respect to a stock deposited should be determined by allocating the value on the date of deposit of the DIAMONDS received (less any cash paid to the Trust, or plus any cash received from the Trust, in connection with the deposit) among the stocks deposited on the basis of their respective fair market values at that time. The IRS may assert that any resulting losses may not be deducted by an investor on the basis that there has been no material change in the investor's economic position or that the transaction has no significant economic or business utility or purpose apart from the anticipated tax consequences. Investors should consult their own tax advisors as to the tax consequences to them of a deposit to the Trust.

The Trustee has the right to reject the order to create Creation Units transmitted to it by the Distributor if the investor or group of investors, upon obtaining the DIAMONDS ordered, would own eighty percent (80%) or more of the outstanding DIAMONDS, and if pursuant to section 351 of the Code such a circumstance would result in the Trust having a basis in the stocks deposited different from the market value of such stocks on the date of deposit. The Trustee has the right to require information regarding DIAMONDS ownership pursuant to the Participant Agreement and from DTC and to rely thereon to the extent necessary to make the foregoing determination as a condition to the acceptance of a Portfolio Deposit.

Subject to the exception described in the following sentence, ordinary income dividends received via DTC by Beneficial Owners who are non-resident aliens are subject to a thirty percent (30%) United States withholding tax unless a reduced rate of withholding or a withholding exemption is provided under applicable tax treaties and appropriate documentation is provided to the Trustee. Ordinary income dividends paid with respect to taxable years of the Trust beginning on or after November 1, 2005 and ending on or before October 31, 2008, will generally not be subject to withholding to the extent that such ordinary income dividends relate to either certain interest income received by the Trust or certain short-term capital gains of the Trust, provided appropriate documentation is provided to the Trustee. The Trust does not expect to pay significant "interest-related dividends" or "short-term capital gains dividends," if any. Non-resident holders of DIAMONDS are urged to consult their own tax advisors concerning the applicability of United States withholding tax.

51

---

Backup withholding at a rate equal to the fourth lowest income tax rate applicable to individuals (which, under current law, is 28%) applies to dividends, capital gain distributions, redemptions and sales of DIAMONDS unless the Beneficial Owner (a) is a corporation or comes within certain other exempt categories and, when required, demonstrates this fact, or (b) provides a taxpayer identification number, certifies as to no loss of exemption from backup withholding, and otherwise complies with applicable requirements of the backup withholding rules. The amount of any backup withholding from a payment to a Beneficial Owner is allowed as a credit against the holder's U.S. federal income tax liability and may entitle such holder to a refund from the IRS, if the required information is furnished to the IRS.

The tax discussion set forth above is included for general information only. Prospective investors should consult their own tax advisors concerning the federal, state, local and foreign tax consequences to them of an investment in the Trust, including the effect of possible legislative changes.

ERISA Considerations

In considering the advisability of an investment in DIAMONDS, fiduciaries of pension, profit sharing or other tax-qualified retirement plans (including Keogh Plans) and welfare plans (collectively, "Plans") subject to the fiduciary responsibility requirements of the Employee Retirement Income Security Act of 1974, as amended ("ERISA"), should consider whether an investment in DIAMONDS (a) is permitted by the documents and instruments governing the Plan, (b) is made solely in the interest of participants and beneficiaries of the Plans, (c) is consistent with the prudence and diversification requirements of ERISA, and that the acquisition and holding of DIAMONDS does not result in a non-exempt "prohibited transaction" under Section 406 of ERISA or Section 4975 of the Code. Individual retirement account ("IRA") investors should consider that an IRA may make only such investments as are authorized by the IRA's governing instruments and that IRAs are subject to the prohibited transaction rules of Section 4975 of the Code.

As described in the preceding paragraph, ERISA imposes certain duties on Plan fiduciaries, and ERISA and/or Section 4975 of the Code prohibit certain transactions involving "plan assets" between Plans or IRAs and persons who have certain specified relationships to the Plan or IRA (that is, "parties in interest" as defined in ERISA or "disqualified persons" as defined in the Code). The fiduciary standards and prohibited transaction rules that apply to an investment in DIAMONDS by a Plan will not apply to transactions involving the Trust's assets because the Trust is an investment company registered under the Investment Company Act of 1940. As such, the Trust's assets are not deemed to be "plan assets" under ERISA and U.S. Department of Labor regulations by virtue of Plan and/or IRA investment in DIAMONDS.

Employee benefit plans that are government plans (as defined in Section 3(32) of ERISA), certain church plans (as defined in Section 3(33) of ERISA)

52

---

and foreign plans (as described in Section 4(b)(4) of ERISA) are not subject to the requirements of ERISA or Section 4975 of the Code. The fiduciaries of governmental plans should, however, consider the impact of their respective state pension codes or other applicable law on investments in DIAMONDS and the considerations discussed above, to the extent such considerations apply.

CONTINUOUS OFFERING OF DIAMONDS

Creation Units are offered continuously to the public by the Trust through the Distributor. Persons making Portfolio Deposits and creating Creation Units receive no fees, commissions or other form of compensation or inducement of any kind from the Sponsor or the Distributor, and no such person has any obligation or responsibility to the Sponsor or Distributor to effect any sale or resale of DIAMONDS.

Because new DIAMONDS can be created and issued on an ongoing basis, at any point during the life of the Trust, a "distribution", as such term is used in the Securities Act of 1933 ("1933 Act"), may be occurring. Broker-dealers and other persons are cautioned that some of their activities may result in their being deemed participants in a distribution in a manner which could render them statutory underwriters and subject them to the prospectus-delivery and liability provisions of the 1933 Act. For example, a broker-dealer firm or its client may be deemed a statutory underwriter if it takes Creation Units after placing a creation order with the Distributor, breaks them down into the constituent DIAMONDS and sells the DIAMONDS directly to its customers; or if it chooses to couple the creation of a supply of new DIAMONDS with an active selling effort involving solicitation of secondary market demand for DIAMONDS. A determination of whether one is an underwriter must take into account all the facts and circumstances pertaining to the activities of the broker-dealer or its client in the particular case, and the examples mentioned above should not be considered a complete description of all the activities that could lead to categorization as an underwriter.

Dealers who are not "underwriters" but are participating in a distribution (as contrasted to ordinary secondary trading transactions), and thus dealing with DIAMONDS that are part of an "unsold allotment" within the meaning of Section 4(3)(C) of the 1933 Act, would be unable to take advantage of the prospectus-delivery exemption provided by Section 4(3) of the 1933 Act.

The Sponsor intends to qualify DIAMONDS in states selected by the Sponsor and through broker-dealers who are members of the National Association of Securities Dealers, Inc. Investors intending to create or redeem Creation Units in transactions not involving a broker-dealer registered in such investor's state of domicile or residence should consult their legal advisor regarding applicable broker-dealer or securities regulatory requirements under the state securities laws prior to such creation or redemption.

DIVIDEND REINVESTMENT SERVICE

The Trust has made the Service available for use by Beneficial Owners through DTC Participants for reinvestment of their cash proceeds. Some DTC Participants may not elect to utilize the Service; therefore, an interested DIAMONDS investor may wish to contact such investor's broker to ascertain the availability of the Service through such broker. Each broker may require investors to adhere to specific procedures and timetables in order to participate in the Service and such investors should ascertain from their broker such necessary details.

Distributions reinvested in additional DIAMONDS through the Service are nevertheless taxable dividends to Beneficial Owners to the same extent as if received in cash.

The Trustee generally uses the cash proceeds of dividends received from all Beneficial Owners participating in reinvestment through the Service to obtain Index Securities necessary to create the requisite number of DIAMONDS at the close of business on each DIAMONDS distribution date. Any cash balance remaining after the requisite number of DIAMONDS has been created is distributed, on a pro rata basis, to all Beneficial Owners who participated in the Service. Brokerage commissions, if any, incurred in obtaining Index Securities necessary to create additional DIAMONDS with the cash from the distributions is an expense of the Trust.*

EXPENSES OF THE TRUST

Until further notice, the Sponsor has undertaken that it will not permit the ordinary operating expenses of the Trust, as calculated by the Trustee, to exceed an amount that is 18/100 of 1% (0.1800%) per annum of the daily NAV of the Trust after taking into account any expense offset credits. To the extent the ordinary operating expenses of the Trust do exceed such 0.1800% amount, the Sponsor will reimburse the Trust for, or assume, the excess. The Sponsor retains the ability to be repaid by the Trust for expenses so reimbursed or assumed to the extent that subsequently during the fiscal year expenses fall below the 0.1800% per annum level on any given day. For purposes of this undertaking, ordinary operating expenses of the Trust do not include taxes, brokerage commissions and any extraordinary non-recurring expenses, including the cost of any litigation to which the Trust or the Trustee may be a party. The Sponsor may discontinue this undertaking or renew it for a specified period of time, or may choose to reimburse or assume certain Trust expenses

*

It is difficult to estimate the annual dollar amount of brokerage commissions that might be incurred in connection with the Dividend Reinvestment Service during any fiscal year. The Trustee estimates that during fiscal year 2005, the approximate amount of annual brokerage commissions incurred in implementing the Service was less than $0.001 per DIAMONDS unit.

in later periods to keep Trust expenses at a level it believes to be attractive to investors. In any event, on any day and during any period over the life of the Trust, total fees and expenses of the Trust may exceed 0.1800% per annum.

Ordinary operating expenses of the Trust are currently being accrued at an annual rate of less than 0.1800%. Future accruals will depend primarily on the level of the Trust's net assets and the level of Trust expenses. There is no guarantee that the Trust's ordinary operating expenses will not exceed 0.1800% of the Trust's daily net asset value and such rate may be changed without notice.

Subject to any applicable cap, the Sponsor may charge the Trust a special fee for certain services the Sponsor may provide to the Trust which would otherwise be provided by the Trustee in an amount not to exceed the actual cost of providing such services. The Sponsor or the Trustee from time to time may voluntarily assume some expenses or reimburse the Trust so that total expenses of the Trust are reduced. Neither the Sponsor nor the Trustee is obligated to do so and either one or both parties may discontinue such voluntary assumption of expenses or reimbursement at any time without notice.

The following charges are or may be accrued and paid by the Trust: (a) the Trustee's fee; (b) fees payable to transfer agents for the provision of transfer agency services; (c) fees of the Trustee for extraordinary services performed under the Trust Agreement; (d) various governmental charges; (e) any taxes, fees and charges payable by the Trustee with respect to DIAMONDS (whether in Creation Units or otherwise); (f) expenses and costs of any action taken by the Trustee or the Sponsor to protect the Trust and the rights and interests of Beneficial Owners of DIAMONDS (whether in Creation Units or otherwise); (g) indemnification of the Trustee or the Sponsor for any losses, liabilities or expenses incurred by it in the administration of the Trust; (h) expenses incurred in contacting Beneficial Owners of DIAMONDS during the life of the Trust and upon termination of the Trust; and (i) other out-of-pocket expenses of the Trust incurred pursuant to actions permitted or required under the Trust Agreement.

In addition, the following expenses are or may be charged to the Trust: (a) reimbursement to the Sponsor of amounts paid by it to Dow Jones in respect of annual licensing fees pursuant to the License Agreement; (b) federal and state annual registration fees for the issuance of DIAMONDS; and (c) expenses of the Sponsor relating to the printing and distribution of marketing materials describing DIAMONDS and the Trust (including, but not limited to, associated legal, consulting, advertising, and marketing costs and other out-of-pocket expenses such as printing). In addition, initial fees and expenses totaling approximately $2,300,000, in connection with the organization of the Trust, were capitalized and amortized over five years from the start of the Trust's operations on a straight-line basis and charged to the Trust. Pursuant to

55

---

the provisions of an exemptive order, the expenses set forth in this paragraph may be charged to the Trust by the Trustee in an amount equal to the actual costs incurred, but in no case shall such charges exceed 20/100 of 1% (0.20%) per annum of the daily NAV of the Trust.

If the income received by the Trust in the form of dividends and other distributions on Portfolio Securities is insufficient to cover Trust expenses, the Trustee may make advances to the Trust to cover such expenses. Otherwise, the Trustee may sell Portfolio Securities in an amount sufficient to pay such expenses. The Trustee may reimburse itself in the amount of any such advance, together with interest thereon at a percentage rate equal to the then current overnight federal funds rate, by deducting such amounts from (a) dividend payments or other income of the Trust when such payments or other income is received, (b) the amounts earned or benefits derived by the Trustee on cash held by the Trustee for the benefit of the Trust, and (c) the sale of Portfolio Securities. Notwithstanding the foregoing, if any advance remains outstanding for more than forty-five (45) Business Days, the Trustee may sell Portfolio Securities to reimburse itself for such advance and any accrued interest thereon. These advances will be secured by a lien on the assets of the Trust in favor of the Trustee. The expenses of the Trust are reflected in the NAV of the Trust.

For services performed under the Trust Agreement, the Trustee is paid a fee at an annual rate of 6/100 of 1% to 10/100 of 1% of the NAV of the Trust, as shown below, such percentage amount to vary depending on the NAV of the Trust, plus or minus the Adjustment Amount. The compensation is computed on each Business Day based on the NAV of the Trust on such day, and the amount thereof is accrued daily and paid quarterly. To the extent that the amount of the Trustee's compensation, before any adjustment in respect of the Adjustment Amount, is less than specified amounts, the Sponsor has agreed to pay the amount of any such shortfall. Notwithstanding the fee schedule set forth in the table below, in the fourth year of the Trust's operation and in subsequent years, the Trustee shall be paid a minimum fee of $400,000 per annum as adjusted by the CPI-U to take effect at the beginning of the fourth year and each year thereafter. To the extent that the amount of the Trustee's compensation, prior to any adjustment in respect of the Adjustment Amount, is less than specified amounts, the Sponsor has agreed to pay the amount of any such shortfall. The Trustee also may waive all or a portion of such fee.

*	The fee indicated applies to that portion of the net asset value of the Trust which falls in the size category indicated.

As of October 31, 2005, and as of December 31, 2005, the NAV of the Trust was $7,409,986,448 and $7,596,106,947, respectively. No representation is made as to the actual NAV of the Trust on any future date as it is subject to change at any time due to fluctuations in the market value of securities or to creations or redemptions made in the future.

The Adjustment Amount is calculated at the end of each quarter and applied against the Trustee's fee for the following quarter. "Adjustment Amount" is an amount which is intended, depending upon the circumstances, either to (a) reduce the Trustee's fee by the amount that the Transaction Fees paid on creation and redemption exceed the costs of those activities, and by the amount of excess earnings on cash held for the benefit of the Trust* or (b) increase the Trustee's fee by the amount that the Transaction Fee (plus additional amounts paid in connection with creations or redemptions outside the DIAMONDS Clearing Process), paid on creations or redemptions, falls short of the actual costs of these activities. If in any quarter the Adjustment Amount exceeds the fee payable to the Trustee as set forth above, the Trustee uses such excess amount to reduce other Trust expenses, subject to certain federal tax limitations. To the extent that the amount of such excess exceeds the Trust's expenses for such quarter, any remaining excess is retained by the Trustee as part of its compensation. If in any quarter the costs of processing creations and redemptions exceed the amounts charged as a Transaction Fee (plus the additional amounts paid in connection with creations or redemptions outside the DIAMONDS Clearing Process) net of the excess earnings, if any, on cash held for the benefit of the Trust, the Trustee will augment the Trustee's fee by the resulting Adjustment Amount. The net Adjustment Amount is usually a credit to the Trust. To make the expense ratio of the Trust comparable to the expense ratio of most other investment companies, it is

shown as a "below the line" adjustment to Trust's expenses. If the adjustment is negative, it is shown "above the line."

VALUATION

The NAV of the Trust is computed as of the Evaluation Time shown under "Summary—Essential Information" on each Business Day. The NAV of the Trust on a per DIAMONDS unit basis is determined by subtracting all liabilities (including accrued expenses and dividends payable) from the total value of the Portfolio and other assets and dividing the result by the total number of outstanding DIAMONDS.

The value of the Portfolio is determined by the Trustee in good faith in the following manner. If Portfolio Securities are listed on one or more national securities exchanges or on the National Market System maintained by the NASDAQ Stock Market ("NASDAQ"), such evaluation is generally based on the closing sale price on that day on the exchange or system which is deemed to be the principal market thereof (the NYSE or the Exchange if the stocks are listed thereon) or in the case of the NASDAQ at the official closing price on that day, (unless the Trustee deems such price inappropriate as a basis for evaluation). If there is no such appropriate closing sale price or NASDAQ official closing price on such exchange or system, the Portfolio Securities will be valued at the last sale price (unless the Trustee deems such price inappropriate as a basis for evaluation). If the stocks are not so listed or, if so listed and the principal market therefor is other than on such exchange or system or there is no such closing sale price available, such evaluation shall generally be made by the Trustee in good faith based on the closing price on the over-the-counter market (unless the Trustee deems such price inappropriate as a basis for evaluation) or if there is no such appropriate closing price, (a) on current bid prices, (b) if bid prices are not available, on the basis of current bid prices for comparable stocks, (c) by the Trustee's appraising the value of the stocks in good faith on the bid side of the market, or (d) by any combination thereof.

ADMINISTRATION OF THE TRUST

Distributions to Beneficial Owners

The regular monthly ex-dividend date for DIAMONDS is the third Friday in each calendar month, unless such day is not a Business Day, in which case the ex-dividend date is the immediately preceding Business Day ("Ex-Dividend Date"). Beneficial Owners reflected on the records of DTC and the DTC Participants on the second Business Day following the Ex-Dividend Date ("Record Date") are entitled to receive an amount representing dividends accumulated on Portfolio Securities through the monthly dividend period which ends on the Business Day preceding such Ex-Dividend Date (including

58

---

stocks with ex-dividend dates falling within such monthly dividend period), net of fees and expenses, accrued daily for such period. For the purposes of all dividend distributions, dividends per DIAMONDS unit are calculated at least to the nearest 1/1000th of $0.01. The payment of dividends is made on the Monday preceding the third (3rd) Friday of the next calendar month or the next subsequent Business Day if such Monday is not a Business Day ("Dividend Payment Date"). Dividend payments are made through DTC and the DTC Participants to Beneficial Owners then of record with funds received from the Trustee.

Dividends payable to the Trust in respect of Portfolio Securities are credited by the Trustee to a non-interest bearing account as of the date on which the Trust receives such dividends. Other moneys received by the Trustee in respect of the Portfolio, including but not limited to the Cash Component, the Cash Redemption Payment, all moneys realized by the Trustee from the sale of options, warrants or other similar rights received or distributed in respect of Portfolio Securities as dividends or distributions and capital gains resulting from the sale of Portfolio Securities are credited by the Trustee to a non-interest bearing account. All funds collected or received are held by the Trustee without interest until distributed in accordance with the provisions of the Trust Agreement. To the extent the amounts credited to the account generate interest income or an equivalent benefit to the Trustee, such interest income or benefit is used to reduce the Trustee's annual fee.

Any additional distributions the Trust may need to make so as to continue to qualify as a "regulated investment company" would consist of (a) an increase in the distribution scheduled for January to include any amount by which estimated Trust investment company taxable income and net capital gains for a year exceeds the amount of Trust taxable income previously distributed with respect to such year or, if greater, the minimum amount required to avoid imposition of such excise tax, and (b) a distribution soon after actual annual investment company taxable income and net capital gains of the Trust have been computed, of the amount, if any, by which such actual income exceeds the distributions already made. The NAV of the Trust is reduced in direct proportion to the amount of such additional distributions. The magnitude of the additional distributions, if any, depends upon a number of factors, including the level of redemption activity experienced by the Trust. Because substantially all proceeds from the sale of stocks in connection with adjustments to the Portfolio are used to purchase shares of Index Securities, the Trust may have no cash or insufficient cash with which to pay such additional distributions. In that case, the Trustee typically has to sell an approximately equal number of shares of each of the Portfolio Securities sufficient to produce the cash required to make such additional distributions.

The Trustee may declare special dividends if such action is necessary or advisable to preserve the status of the Trust as a regulated investment company or to avoid imposition of income or excise taxes on undistributed income, and

59

---

to vary the frequency with which periodic distributions are made (e.g., from monthly to quarterly) if it is determined by the Sponsor and the Trustee that such a variance would be advisable to facilitate compliance with the rules and regulations applicable to regulated investment companies or would otherwise be advantageous to the Trust. In addition, the Trustee may change the regular ex-dividend date for DIAMONDS to another date within the month or the quarter if it is determined by the Sponsor and the Trustee that such a change would be advantageous to the Trust. Notice of any such variance or change shall be provided to Beneficial Owners via DTC and the DTC Participants.

As soon as practicable after notice of termination of the Trust, the Trustee will distribute via DTC and the DTC Participants to each Beneficial Owner redeeming Creation Units before the termination date specified in such notice a portion of Portfolio Securities and cash as described above. Otherwise, the Trustee will distribute to each Beneficial Owner (whether in Creation Unit size aggregations or otherwise), as soon as practicable after termination of the Trust, such Beneficial Owner's pro rata share of the NAV of the Trust.

All distributions are made by the Trustee through DTC and the DTC Participants to Beneficial Owners as recorded on the book entry system of DTC and the DTC Participants.

The settlement date for the creation of DIAMONDS or the purchase of DIAMONDS in the secondary market must occur on or before the Record Date in order for such creator or purchaser to receive a distribution on the next Dividend Payment Date. If the settlement date for such creation or a secondary market purchase occurs after the Record Date, the distribution will be made to the prior securityholder or Beneficial Owner as of such Record Date.

Any Beneficial Owner interested in acquiring additional DIAMONDS with proceeds received from distributions described above may elect dividend reinvestment through DTC Participants by means of the Service, if such service is available through the Beneficial Owner's broker.

Statements to Beneficial Owners; Annual Reports

With each distribution, the Trustee furnishes for distribution to Beneficial Owners a statement setting forth the amount being distributed, expressed as a dollar amount per DIAMONDS unit.

Promptly after the end of each fiscal year, the Trustee furnishes to the DTC Participants for distribution to each person who was a Beneficial Owner of DIAMONDS at the end of such fiscal year, an annual report of the Trust containing financial statements audited by independent accountants of nationally recognized standing and such other information as may be required by applicable laws, rules and regulations.

Rights of Beneficial Owners

Beneficial Owners may sell DIAMONDS in the secondary market, but must accumulate enough DIAMONDS to constitute a full Creation Unit in order to redeem through the Trust. The death or incapacity of any Beneficial Owner does not operate to terminate the Trust nor entitle such Beneficial Owner's legal representatives or heirs to claim an accounting or to take any action or proceeding in any court for a partition or winding up of the Trust.

Beneficial Owners shall not (a) have the right to vote concerning the Trust, except with respect to termination and as otherwise expressly set forth in the Trust Agreement, (b) in any manner control the operation and management of the Trust, or (c) be liable to any other person by reason of any action taken by the Sponsor or the Trustee. The Trustee has the right to vote all of the voting stocks in the Trust. The Trustee votes the voting stocks of each issuer in the same proportionate relationship as all other shares of each such issuer are voted to the extent permissible and, if not permitted, abstains from voting.

Amendments to the Trust Agreement

The Trust Agreement may be amended from time to time by the Trustee and the Sponsor without the consent of any Beneficial Owners (a) to cure any ambiguity or to correct or supplement any provision that may be defective or inconsistent or to make such other provisions as will not adversely affect the interests of Beneficial Owners; (b) to change any provision as may be required by the SEC; (c) to add or change any provision as may be necessary or advisable for the continuing qualification of the Trust as a "regulated investment company" under the Code; (d) to add or change any provision as may be necessary or advisable if NSCC or DTC is unable or unwilling to continue to perform its functions; and (e) to add or change any provision to conform the adjustments to the Portfolio and the Portfolio Deposit to changes, if any, made by Dow Jones in its method of determining the DJIA. The Trust Agreement may also be amended by the Sponsor and the Trustee with the consent of the Beneficial Owners of 51% of the outstanding DIAMONDS to add provisions to, or change or eliminate any of the provisions of, the Trust Agreement or to modify the rights of Beneficial Owners; although, the Trust Agreement may not be amended without the consent of the Beneficial Owners of all outstanding DIAMONDS if such amendment would (a) permit the acquisition of any securities other than those acquired in accordance with the terms and conditions of the Trust Agreement; (b) reduce the interest of any Beneficial Owner in the Trust; or (c) reduce the percentage of Beneficial Owners required to consent to any such amendment.

Promptly after the execution of an amendment, the Trustee receives from DTC, pursuant to the terms of the Depository Agreement, a list of all DTC Participants holding DIAMONDS. The Trustee inquires of each such DTC

61

---

Participant as to the number of Beneficial Owners for whom such DTC Participant holds DIAMONDS, and provides each such DTC Participant with sufficient copies of a written notice of the substance of such amendment for transmittal by each such DTC Participant to Beneficial Owners.

Termination of the Trust Agreement

The Trust Agreement provides that the Sponsor has the discretionary right to direct the Trustee to terminate the Trust if at any time the NAV of the Trust is less than $350,000,000, as such dollar amount shall be adjusted for inflation in accordance with the CPI-U. This adjustment is to take effect at the end of the fourth year following the Initial Date of Deposit and at the end of each year thereafter and to be made so as to reflect the percentage increase in consumer prices as set forth in the CPI-U for the twelve month period ending in the last month of the preceding fiscal year.

The Trust may be terminated (a) by the agreement of the Beneficial Owners of 66 2/3% of outstanding DIAMONDS; (b) if DTC is unable or unwilling to continue to perform its functions as set forth under the Trust Agreement and a comparable replacement is unavailable; (c) if NSCC no longer provides clearance services with respect to DIAMONDS, or if the Trustee is no longer a participant in NSCC; (d) if Dow Jones ceases publishing the DJIA; (e) if the License Agreement is terminated; or (f) if DIAMONDS are delisted from the Exchange. The Trust will also terminate by its terms on the Termination Date.

The Trust will terminate if either the Sponsor or the Trustee resigns or is removed and a successor is not appointed. The dissolution of the Sponsor or its ceasing to exist as a legal entity for any cause whatsoever, however, will not cause the termination of the Trust Agreement or the Trust unless the Trustee deems termination to be in the best interests of Beneficial Owners.

Prior written notice of the termination of the Trust must be given at least twenty (20) days before termination of the Trust to all Beneficial Owners. The notice must set forth the date on which the Trust will be terminated, the period during which the assets of the Trust will be liquidated, the date on which Beneficial Owners of DIAMONDS (whether in Creation Unit size aggregations or otherwise) will receive in cash the NAV of the DIAMONDS held, and the date upon which the books of the Trust shall be closed. The notice shall further state that, as of the date thereof and thereafter, neither requests to create additional Creation Units nor Portfolio Deposits will be accepted, that no additional DIAMONDS will be created for the purpose of reinvesting dividend distributions, and that, as of the date thereof and thereafter, the portfolio of stocks delivered upon redemption shall be identical in composition and weighting to Portfolio Securities as of such date rather than the stock portion of the Portfolio Deposit as in effect on the date request for redemption is deemed received. Beneficial Owners of Creation Units may, in advance of the Termination Date, redeem in kind directly from the Trust.

62

---

Within a reasonable period after the Termination Date, the Trustee shall, subject to any applicable provisions of law, use its best efforts to sell all of the Portfolio Securities not already distributed to redeeming Beneficial Owners of Creation Units. The Trustee shall not be liable for or responsible in any way for depreciation or loss incurred because of any such sale. The Trustee may suspend such sales upon the occurrence of unusual or unforeseen circumstances, including but not limited to a suspension in trading of a stock, the closing or restriction of trading on a stock exchange, the outbreak of hostilities, or the collapse of the economy. The Trustee shall deduct from the proceeds of sale its fees and all other expenses and transmit the remaining amount to DTC for distribution, together with a final statement setting forth the computation of the gross amount distributed.

DIAMONDS not redeemed before termination of the Trust will be redeemed in cash at NAV based on the proceeds of the sale of Portfolio Securities, with no minimum aggregation of DIAMONDS required.

SPONSOR

The Sponsor is a Delaware limited liability company incorporated on April 6, 1998 with offices c/o the American Stock Exchange LLC, 86 Trinity Place, New York, New York 10006. The Sponsor's Internal Revenue Service Employer Identification Number is 52-2127241. The Exchange is the sole member of the Sponsor and the Exchange is a "control person" of the Sponsor as such term is defined in the Securities Act of 1933.

The Sponsor, at its own expense, may from time to time provide additional promotional incentives to brokers who sell DIAMONDS to the public. In certain instances, these incentives may be provided only to those brokers who meet certain threshold requirements for participation in a given incentive program, such as selling a significant number of DIAMONDS within a specified period.

If at any time the Sponsor fails to undertake or perform or becomes incapable of undertaking or performing any of the duties required under the Trust Agreement, or resigns, or becomes bankrupt or its affairs are taken over by public authorities, the Trustee may appoint a successor Sponsor, agree to act as Sponsor itself, or may terminate the Trust Agreement and liquidate the Trust. Notice of the resignation or removal of the Sponsor and the appointment of a successor shall be mailed by the Trustee to DTC and the DTC Participants for distribution to Beneficial Owners. Upon a successor Sponsor's execution of a written acceptance of appointment as Sponsor of the Trust, the successor Sponsor becomes vested with all of the rights, powers, duties and obligations of the original Sponsor. Any successor Sponsor may be compensated at rates deemed by the Trustee to be reasonable.

The Sponsor may resign by executing and delivering to the Trustee an instrument of resignation. Such resignation shall become effective upon the

63

---

appointment of a successor Sponsor and the acceptance of appointment by the successor Sponsor, unless the Trustee either agrees to act as Sponsor or terminates the Trust Agreement and liquidates the Trust. The dissolution of the Sponsor or its ceasing to exist as a legal entity for any cause whatsoever will not cause the termination of the Trust Agreement or the Trust unless the Trustee deems termination to be in the best interests of the Beneficial Owners of DIAMONDS.

The Trust Agreement provides that the Sponsor is not liable to the Trustee, the Trust or to the Beneficial Owners of DIAMONDS for taking any action, or for refraining from taking any action, made in good faith or for errors in judgment, but is liable only for its own gross negligence, bad faith, willful misconduct or willful malfeasance in the performance of its duties or its reckless disregard of its obligations and duties under the Trust Agreement. The Sponsor is not liable or responsible in any way for depreciation or loss incurred by the Trust because of the sale of any Portfolio Securities. The Trust Agreement further provides that the Sponsor and its directors, subsidiaries, shareholders, officers, employees, and affiliates under common control with the Sponsor shall be indemnified from the assets of the Trust and held harmless against any loss, liability or expense incurred without gross negligence, bad faith, willful misconduct or willful malfeasance on the part of any such party in the performance of its duties or reckless disregard of its obligations and duties under the Trust Agreement, including the payment of the costs and expenses of defending against any claim or liability.

TRUSTEE

The Trustee is a bank and trust company organized under the laws of the Commonwealth of Massachusetts with its principal place of business at One Lincoln Street, Boston, Massachusetts 02111. The Trustee's Internal Revenue Service Employer Identification Number is 04-1867445. The Trustee is subject to supervision and examination by the Massachusetts Division of Banks and the Federal Reserve Bank of Boston.

Information regarding Cash Redemption Payment amounts, number of outstanding DIAMONDS and Transaction Fees may be obtained from the Trustee at the toll-free number: 1-800-545-4189. Complete copies of the Trust Agreement and a list of the parties that have executed a Participant Agreement may be obtained from the Trustee's principal office.

The Trustee may resign and be discharged of the Trust created by the Trust Agreement by executing a notice of resignation in writing and filing such notice with the Sponsor and mailing a copy of the notice of resignation to all DTC Participants reflected on the records of DTC as owning DIAMONDS for distribution to Beneficial Owners as provided above not less than sixty (60) days before the date such resignation is to take effect. Such resignation becomes effective upon the appointment of and the acceptance of the Trust by

64

---

a successor Trustee. The Sponsor, upon receiving notice of such resignation, is obligated to use its best efforts to appoint a successor Trustee promptly. If no successor is appointed within sixty (60) days after the date such notice of resignation is given, the Trust shall terminate.

If the Trustee becomes incapable of acting as such or is adjudged bankrupt or is taken over by any public authority, the Sponsor may discharge the Trustee and appoint a successor Trustee as provided in the Trust Agreement. The Sponsor shall mail notice of such discharge and appointment via the DTC Participants to Beneficial Owners. Upon a successor Trustee's execution of a written acceptance of an appointment as Trustee for the Trust, the successor Trustee becomes vested with all the rights, powers, duties and obligations of the original Trustee. A successor Trustee must be (a) a trust company, corporation or national banking association organized, doing business under the laws of the United States or any state thereof; (b) authorized under such laws to exercise corporate trust powers; and (c) at all times have an aggregate capital, surplus and undivided profit of not less than $50,000,000.

Beneficial Owners of 51% of the then outstanding DIAMONDS may at any time remove the Trustee by written instrument(s) delivered to the Trustee and the Sponsor. The Sponsor shall thereupon use its best efforts to appoint a successor Trustee as described above.

The Trust Agreement limits the Trustee's liabilities. It provides, among other things, that the Trustee is not liable for (a) any action taken in reasonable reliance on properly executed documents or for the disposition of monies or stocks or for the evaluations required to be made thereunder, except by reason of its own gross negligence, bad faith, willful malfeasance, willful misconduct, or reckless disregard of its duties and obligations; (b) depreciation or loss incurred by reason of the sale by the Trustee of any Portfolio Securities; (c) any action the Trustee takes where the Sponsor fails to act; and (d) any taxes or other governmental charges imposed upon or in respect of Portfolio Securities or upon the interest thereon or upon it as Trustee or upon or in respect of the Trust which the Trustee may be required to pay under any present or future law of the United States of America or of any other taxing authority having jurisdiction.

The Trustee and its directors, subsidiaries, shareholders, officers, employees, and affiliates under common control with the Trustee will be indemnified from the assets of the Trust and held harmless against any loss, liability or expense incurred without gross negligence, bad faith, willful misconduct, willful malfeasance on the part of such party or reckless disregard of its duties and obligations, arising out of, or in connection with its acceptance or administration of the Trust, including the costs and expenses (including counsel fees) of defending against any claim or liability.

LEGAL OPINION

The legality of the DIAMONDS offered hereby has been passed upon by Carter Ledyard & Milburn LLP, New York, New York, as counsel for the Sponsor.

INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The financial statements as of October 31, 2005 included in this Prospectus have been so included in reliance upon the report of PricewaterhouseCoopers LLP, independent registered public accounting firm, 125 High Street, Boston, Massachusetts, given on the authority of said firm as experts in auditing and accounting.

CODE OF ETHICS

The Trust and the Sponsor have adopted a code of ethics regarding personal securities transactions by employees. Subject to certain conditions and standards, the code permits employees to invest in DIAMONDS for their own accounts. The code is designed to prevent fraud, deception and misconduct against the Trust and to provide reasonable standards of conduct. The code is on file with the SEC and you may obtain a copy by visiting the SEC at the address listed on the back cover of this prospectus. The code is also available on the EDGAR Database on the SEC's Internet site at http:/www.sec.gov. A copy may be obtained, after paying a duplicating fee, by electronic request at publicinfo@sec.gov, or by writing the SEC at the address listed on the back cover of this prospectus.

DAILY DIAMONDS TRADING INFORMATION

The Sponsor makes available daily a list of the names and the required number of shares of each of the Securities in the current Portfolio Deposit. The Sponsor also intends to make available (a) on a daily basis, the Dividend Equivalent Payment effective through and including the previous Business Day, per outstanding DIAMONDS unit, and (b) every 15 seconds throughout the trading day at the Exchange a number representing, on a per DIAMONDS unit basis, the sum of the Dividend Equivalent Payment effective through and including the previous Business Day, plus the current value of the securities portion of a Portfolio Deposit as in effect on such day (which value may include a cash in lieu amount to compensate for the omission of a particular Index Security from such Portfolio Deposit). Intra-day information will be available with respect to trades and quotes and underlying trading values will

66

---

be published every 15 seconds throughout the trading day. Information with respect to net asset value, net accumulated dividend, final dividend amount to be paid, shares outstanding, estimated cash amount and total cash amount per Creation Unit will be available daily prior to the opening of trading on the Exchange.

INFORMATION AND COMPARISONS RELATING TO TRUST,
SECONDARY MARKET TRADING, NET ASSET SIZE, PERFORMANCE AND TAX TREATMENT

Information regarding various aspects of the Trust, including the net asset size thereof, as well as the secondary market trading, the performance and the tax treatment of DIAMONDS, may be included from time to time in advertisements, sales literature and other communications and in reports to current or prospective Beneficial Owners. Any such performance-related information will reflect only past performance of DIAMONDS, and no guarantees can be made of future results.

Specifically, information may be provided to investors regarding the ability to engage in short sales of DIAMONDS, including reference to the exemption from the "tick test" provision of the SEC short sale rule (Rule 10a-1 under the Securities Exchange Act of 1934), to permit short sales on "minus" or "zero-minus" ticks. Selling short refers to the sale of securities which the seller does not own, but which the seller arranges to borrow before effecting the sale. Institutional investors may be advised that lending their DIAMONDS to short sellers may generate stock loan credits that may supplement the return they can earn from an investment in DIAMONDS. These stock loan credits may provide a useful source of additional income for certain institutional investors who can arrange to lend DIAMONDS. Potential short sellers may be advised that a short rebate (functionally equivalent to partial use of proceeds of the short sale) may reduce their cost of selling short.

In addition, information may be provided to prospective or current investors comparing and contrasting the tax efficiencies of conventional mutual funds with DIAMONDS. Both conventional mutual funds and the Trust may be required to recognize capital gains incurred as a result of adjustments to the composition of the DJIA and therefore to their respective portfolios. From a tax perspective, however, a significant difference between a conventional mutual fund and the Trust is the process by which their shares are redeemed. In cases where a conventional mutual fund experiences redemptions in excess of subscriptions ("net redemptions") and has insufficient cash available to fund such net redemptions, such fund may have to sell stocks held in its portfolio to raise and pay cash to redeeming shareholders. A mutual fund will generally experience a taxable gain or loss when it sells such portfolio stocks in order to pay cash to redeeming fund shareholders. In contrast, the redemption mechanism for DIAMONDS does not involve selling the portfolio stocks. Instead, the Trust delivers the actual portfolio of stocks in an in-kind exchange to any

67

---

person redeeming DIAMONDS in Creation Unit size aggregations. While this in-kind exchange is a taxable transaction to the redeeming entity (usually a broker/dealer) making the exchange, it generally does not constitute a taxable transaction at the Trust level and, consequently, there is no realization of taxable gain or loss by the Trust with respect to such in-kind exchanges. In a period of market appreciation of the DJIA and, consequently, appreciation of the portfolio stocks held in the Trust, this in-kind redemption mechanism has the effect of eliminating the recognition and distribution of those net unrealized gains at the Trust level. Although the same result would obtain for conventional mutual funds utilizing an in-kind redemption mechanism, the opportunities to redeem fund shares by delivering portfolio stocks in-kind are limited in most mutual funds.

Investors may be informed that, while no unequivocal statement can be made as to the net tax impact on a conventional mutual fund resulting from the purchases and sales of its portfolio stocks over a period of time, conventional funds that have accumulated substantial unrealized capital gains, if they experience net redemptions and do not have sufficient available cash, may be required to make taxable capital gains distributions that are generated by changes in such fund's portfolio. In contrast, the in-kind redemption mechanism of DIAMONDS may make them more tax efficient investments under most circumstances than comparable conventional mutual fund shares. As discussed above, this in-kind redemption feature tends to lower the amount of annual net capital gains distributions to DIAMONDS holders as compared to their conventional mutual fund counterparts. Since shareholders are generally required to pay income tax on capital gains distributions, the smaller the amount of such distributions, the less taxes that are payable currently. To the extent that the Trust is not required to recognize capital gains, the DIAMONDS holder is able, in effect, to defer tax on such gains until he sells or otherwise disposes of his shares, or the Trust terminates. If such holder retains his shares until his death, under current law the tax basis of such shares would be adjusted to their then fair market value.

One important difference between DIAMONDS and conventional mutual fund shares is that DIAMONDS are available for purchase or sale on an intraday basis on the Exchange. An investor who buys shares in a conventional mutual fund will buy or sell shares at a price at or related to the closing NAV per share, as determined by the fund. In contrast, DIAMONDS are not offered for purchase or redeemed for cash at a fixed relationship to closing NAV. The tables below illustrate the distribution relationship of DIAMONDS closing prices to NAV for the period 1/20/98 (the first trading date of the DIAMONDS Trust) through 12/31/05, the distribution relationships of high, low and closing prices over the same period, and distribution of bid/ask spreads for 2005. This table should help investors evaluate some of the advantages and disadvantages of DIAMONDS relative to funds sold and redeemed at prices related to closing NAV. Specifically, the table illustrates in an approximate way the risks

68

---

of buying or selling DIAMONDS at prices less favorable than closing NAV and, correspondingly, the opportunities to buy or sell at prices more favorable than closing NAV.

The investor may wish to evaluate the opportunity to buy or sell on an intraday basis versus the assurance of a transaction at or related to closing NAV. To assist investors in making this comparison, the table illustrates the distribution of percentage ranges between the high and the low price each day and between each extreme daily value and the closing NAV for all trading days from 1/20/98 through 12/31/05. The investor may wish to compare these ranges with the average bid/ask spread on DIAMONDS and add any commissions charged by a broker. The trading ranges for this period will not necessarily be typical of trading ranges in future years and the bid/ask spread on DIAMONDS may vary materially over time and may be significantly greater at times in the future. There is some evidence, for example, that the bid/ask spread will widen in markets that are more volatile and narrow when markets are less volatile. Consequently, the investor should expect wider bid/ask spreads to be associated with wider daily spread ranges.
