NEW YORK PUT SERIES PORTFOLIO--RISK/RETURN SUMMARY

<TABLE>
<C>  <S>
 1.  WHAT ARE THE FUND'S OBJECTIVES?
  -  The Fund seeks interest income that is
     exempt from regular federal income taxes
     by investing in a fixed portfolio
     consisting primarily of intermediate and
     long term municipal bonds with an
     estimated average life of about 13
     years, issued by or on behalf of the
     State of New York or its local
     governments and authorities.

  -  The Fund seeks to reduce fluctuations in
     the value of the bonds (and minimize the
     risk of losing money) through the
     repurchase commitments described below.

 2.  WHAT ARE MUNICIPAL REVENUE BONDS?
     Municipal industrial development revenue
     bonds are bonds issued by states,
     municipalities and public authorities to
     finance the cost of buying, building or
     improving various projects intended to
     generate revenue, such as airport,
     healthcare, housing and municipal
     utilities. Generally, payments on these
     bonds depend solely on the revenues
     generated by the project, excise taxes
     or state appropriations, and are not
     backed by the government's taxing power.

 3.  WHAT IS THE FUND'S INVESTMENT STRATEGY?
  -  The Fund plans to hold to maturity 7
     collateralized tax-exempt municipal
     bonds with an aggregate face amount of
     $4,007,532.
  -  The Fund is a unit investment trust
     which means that, unlike a mutual fund,
     the Portfolio is not managed.
  -  The approximate percentage of the
     Portfolio backed by each Seller's
     repurchase commitments is:
</TABLE>

    The Savings Bank of Utica
       (Utica, NY)                                                           59%
    The Dime Savings Bank of New York
       (Brooklyn, NY)                                                         1%
    Fleet Financial (Providence, RI)                                          2%
    The Binghamton Savings Bank
       (Binghamton, NY)                                                      38%

<TABLE>
<C>  <S>
  -  The bonds were initially acquired from
     savings banks (the Sellers), which had
     held the bonds in their own portfolios.
  -  Approximately 34% of the bonds are moral
     obligation bonds. Generally the agency or
     authority issuing the bonds has no taxing
     power, and repayment of these bonds is
     only a moral commitment, but not a legal
     obligation of the state or municipality.
  -  The fund is concentrated in refunded
     bonds.
</TABLE>

The Portfolio contains municipal bonds of the following types:

<TABLE>
  -  General Obligation                        2%
<C>  <S>
  -  Hospital/Health Care                     29%
  -  Housing                                  35%
  -  Refunded Bonds                          23%
  -  Universities/Colleges                    11%
</TABLE>

<TABLE>
<C>  <S>
  -  Each Seller has agreed to repurchase on
     Annual Repurchase Dates any of the bonds
     sold by it to the Fund if:
     -- the Fund needs to sell bonds to meet
        redemptions of units;
     -- the issuer of a bond fails to make
        payments when due;
     -- the interest on a bond becomes taxable;
        and
     -- insolvency proceedings are commenced by
        or against the Seller, or it fails to
        meet its collateral requirements.
</TABLE>

<TABLE>
<C>  <S>
  -  Each Seller has also agreed to repurchase
     its bonds on scheduled disposition dates.
  -  The collateral securing the Sellers'
     repurchase commitments may include:
     -- Ginnie Maes, Fannie Maes and Freddie
        Macs;
     -- mortgages;
     -- municipal obligations;
     -- corporate obligations;
     -- U.S. government securities; and
     -- cash.
  -  You should rely on the collateral for the
     performance of the repurchase commitments
     rather than on the financial position of
     the Sellers.

 4.  WHAT ARE THE SIGNIFICANT RISKS?
     YOU CAN LOSE MONEY BY INVESTING IN THE
     FUND. THIS CAN HAPPEN FOR VARIOUS
     REASONS, INCLUDING:
  -  Rising interest rates, an issuer's
     worsening financial condition or a
     Seller's failure to meet its repurchase
     commitments can reduce the price of your
     units.
  -  Since the Fund is concentrated in
     hospital/health care and housing bonds,
     adverse developments in these sectors may
     affect the value of your units.
  -  Assuming no changes in interest rates,
     when you sell your units, they will
     generally be worth less than your cost
     because your cost included a sales fee.
</TABLE>

                                       3
<PAGE>

<TABLE>
<C>  <S>
  -  The Fund could receive early returns of
     principal if mortgages underlying some
     of the bonds are prepaid, if it becomes
     necessary to liquidate the collateral or
     if bonds are called or sold before they
     mature. If this happens your income will
     decline and you may not be able to
     reinvest the money you receive at as
     high a yield or as long a maturity.
  -  86% of the bonds are currently callable.

     ALSO, THE PORTFOLIO IS CONCENTRATED IN
     BONDS OF NEW YORK SO IT IS LESS
     DIVERSIFIED THAN A NATIONAL FUND AND IS
     SUBJECT TO RISKS PARTICULAR TO NEW YORK
     WHICH ARE BRIEFLY DESCRIBED UNDER STATE
     CONCENTRATION RISKS LATER IN THIS
     PROSPECTUS.

 5.  IS THIS FUND APPROPRIATE FOR YOU?

     Yes, if you want federally tax-free
     income. You will benefit from a
     professionally selected and supervised
     portfolio whose risk is reduced by
     investing in bonds backed by
     collateralized repurchase commitments.
     The Fund is NOT appropriate for you if
     you want a speculative investment that
     changes to take advantage of market
     movements, if you do not want a
     tax-advantaged investment or if you
     cannot tolerate any risk.

 7.  IS THE FUND MANAGED?

     Unlike a mutual fund, the Fund is not
     managed and bonds are not sold because of
     market changes. Rather, experienced
     Defined Asset Funds financial analysts
     regularly review the bonds in the Fund.
     The Fund may sell a bond if certain
     adverse credit or other conditions exist.

 8.  HOW DO I BUY UNITS?

     The minimum investment is one unit.

     You can buy units from any of the
     Sponsors and other broker-dealers. The
     Sponsors are listed later in this
     prospectus. Some banks may offer units
     for sale through special arrangements
     with the Sponsors, although certain legal
     restrictions may apply.

     UNIT PRICE PER UNIT               $159.77
     (as of March 31, 2000)

     Unit price is based on the net asset
     value of the Fund plus the sales fee. An
     amount equal to any principal cash, as
     well as net accrued but undistributed
     interest on the unit, is added to the
     unit price. An independent evaluator
     prices the bonds at 3:30 p.m. Eastern
     time every business day. Unit price
     changes every day with changes in the
     prices of the bonds in the Fund.

 9.  HOW DO I SELL UNITS?

     You may sell your units at any time to
     any Sponsor or the Trustee for the net
     asset value determined at the close of
     business on the date of sale. You will
     not pay any other fee when you sell your
     units.

10.  HOW ARE DISTRIBUTIONS MADE AND TAXED?

     The Fund pays income monthly.

     In the opinion of bond counsel when each
     bond was issued, interest on the bonds in
     this Fund is generally 100% exempt from
     regular federal income tax.

     You will also receive principal payments
     if bonds are sold or called or mature,
     when the cash available is more than
     $5.00 per unit. You will be subject to
     tax on any gain realized by the Fund on
     the disposition of bonds.

<C>  <S>
11.  WHAT OTHER SERVICES ARE AVAILABLE?

     REINVESTMENT
     You will receive your income in cash
     unless you choose to compound your
     income by reinvesting at no sales fee in
     the Municipal Fund Investment
     Accumulation Program, Inc. This Program
     is an open-end mutual fund with a
     comparable investment objective. Income
     from this Program will generally be
     subject to state and local income taxes.
     FOR MORE COMPLETE INFORMATION ABOUT THE
     PROGRAM, INCLUDING CHARGES AND FEES, ASK
     THE TRUSTEE FOR THE PROGRAM'S
     PROSPECTUS. READ IT CAREFULLY BEFORE YOU
     INVEST. THE TRUSTEE MUST RECEIVE YOUR
     WRITTEN ELECTION TO REINVEST AT LEAST 10
     DAYS BEFORE THE RECORD DAY OF AN INCOME
     PAYMENT.

     EXCHANGE PRIVILEGES

     units of certain other Defined Asset
     Funds. You may also exchange into this
     Fund from certain other funds. We charge
     a reduced sales fee on most exchanges.

To compare the yield of a taxable security with the yield of a tax-free
security, find your taxable income and read across. The table incorporates 2000
federal and applicable State (and City) income tax rates and assumes that all
income would otherwise be taxed at the investor's highest tax rate. Yield
figures are for example only.

*Based upon net amount subject to federal income tax after deductions and
exemptions. This table does not reflect the possible effect of other tax
factors, such as alternative minimum tax, personal exemptions, the phase out of
exemptions, itemized deductions or the possible partial disallowance of
deductions. Consequently, investors are urged to consult their own tax advisers
in this regard.

WHAT YOU CAN EXPECT FROM YOUR INVESTMENT

MONTHLY INCOME

The Fund will pay you regular monthly income. Your monthly income may vary
because of:
  - elimination of one or more bonds from the Fund's portfolio because of calls,
    redemptions or sales;
  - a change in the Fund's expenses; or
  - the failure by a bond's issuer to pay interest.

Changes in interest rates generally will not affect your income because the
portfolio is fixed.

Along with your income, you will receive your share of any available bond
principal.

RETURN FIGURES

We cannot predict your actual return, which will vary with unit price, how long
you hold your investment and changes in the portfolio, interest income and
expenses.

ESTIMATED CURRENT RETURN equals the estimated annual cash to be received from
the bonds in the Fund less estimated annual Fund expenses, divided by the Unit
Price (including the maximum sales fee):

<TABLE>
<S>              <C>  <C>
Estimated Annual         Estimated
Interest Income   -   Annual Expenses
-------------------------------------
             Unit Price
</TABLE>

ESTIMATED LONG TERM RETURN is a measure of the estimated return over the
estimated life of the Fund. Unlike Estimated Current Return, Estimated Long Term
Return reflects maturities, discounts and premiums of the bonds in the Fund. It
is an average of the yields to maturity (or in certain cases, to an earlier call
date) of the individual bonds in the portfolio, adjusted to reflect the Fund's
maximum sales fee and estimated expenses. We calculate the average yield for the
portfolio by weighting each bond's yield by its market value and the time
remaining to the call or maturity date.

Yields on individual bonds depend on many factors including general conditions
of the bond markets, the size of a particular offering and the maturity and
quality rating of the particular issues. Yields can vary among bonds with
similar maturities, coupons and ratings.

These return quotations are designed to be comparative rather than predictive.

RECORDS AND REPORTS

You will receive:
- a monthly statement of income payments and any principal payments;
- a notice from the Trustee when new bonds are deposited in exchange or
  substitution for bonds originally deposited;
- an annual report on Fund activity; and
- annual tax information. THIS WILL ALSO BE SENT TO THE IRS. YOU MUST REPORT THE
  AMOUNT OF TAX-EXEMPT INTEREST RECEIVED DURING THE YEAR.

You may request:
- copies of bond evaluations to enable you to comply with federal and state tax
  reporting requirements; and
- audited financial statements of the Fund.

You may inspect records of Fund transactions at the Trustee's office during
regular business hours.

                                       6

THE RISKS YOU FACE

INTEREST RATE RISK

Investing involves risks, including the risk that your investment will decline
in value if interest rates rise. Generally, bonds with longer maturities will
change in value more than bonds with shorter maturities. Bonds in the Fund are
more likely to be called when interest rates decline. This would result in early
returns of principal to you and may result in early termination of the Fund. Of
course, we cannot predict how interest rates may change.

CALL RISK

All the bonds in this Fund are currently callable by the issuer.

If the bonds are called, your income will decline and you may not be able to
reinvest the money you receive at as high a yield or as long a maturity. An
early call at par of a premium bond will reduce your return.

REDUCED DIVERSIFICATION RISK

If many investors sell their units, the Fund will have to sell bonds. This could
reduce the diversification of your investment and increase your share of Fund
expenses.

LIQUIDITY RISK

You can always sell back your units, but we cannot assure you that a liquid
trading market will always exist for the bonds in the portfolio, especially
since current law may restrict the Fund from selling bonds to any Sponsor. The
bonds will generally trade in the over-the-counter market. The value of the
bonds, and of your investment, may be reduced if trading in bonds is limited or
absent.

COLLATERAL RELATED RISK

The Sponsors believe that the collateral is reasonably adequate to support the
repurchase commitments without regard to the ability of the Sellers to meet
these commitments.

You could have all or part of the principal amount of your investment returned
early if insolvency proceedings are commenced by or against a Seller. In that
case, the collateral agent will automatically foreclose on the collateral and,
if necessary, liquidate it and use the proceeds to purchase bonds from the Fund.
You would then receive your share of the proceeds.

The Sponsors have agreed that their sole recourse in the event a Seller fails to
repurchase the bonds as agreed, including as a result of the Seller's
insolvency, will be to exercise available remedies with respect to the
collateral on deposit with the Fund. If the collateral is not enough to cover
the costs resulting from the Seller's default, the Sponsors will be unable to
pursue any deficiency judgment against the Seller.

CONCENTRATION RISK

When a certain type of bond makes up 25% or more of the portfolio, it is said to
be 'concentrated' in that bond type, which makes the Portfolio less diversified.

Here is what you should know about the Fund's concentration in hospital and
health care bonds:
  - payment for these bonds depends on revenues from private third-party payors
    and government programs, including Medicare and Medicaid, which have

                                       7
<PAGE>
    generally undertaken cost containment measures to limit payments to health
    care providers;
  - hospitals face increasing competition resulting from hospital mergers and
    affiliations;
  - hospitals need to reduce costs as HMOs increase market penetration and
    hospital supply and drug companies raise prices; and
  - hospitals and health care providers are subject to various legal claims by
    patients and others and are adversely affected by increasing costs of
    insurance.
  - many hospitals are aggressively buying physician practices and assuming risk
    contracts to gain market share. If revenues do not increase accordingly,
    this practice could reduce profits.
  - Medicare is changing its reimbursement system for nursing homes. Many
    nursing home providers are not sure how they will be treated. In many cases,
    the providers may receive lower reimbursements and these would have to cut
    expenses to maintain profitability.
  - most retirement/nursing home providers rely on entrance fees for operating
    revenues. If people live longer than expected and turnover is lower than
    budgeted, operating revenues would be adversely affected by less than
    expected entrance fees.

Here is what you should know about the Fund's concentration in housing bonds.
Multi-family housing revenue bonds and single family mortgage revenue bonds are
issued to provide financing for various housing projects. These bonds are
payable primarily from the revenue derived from mortgage loans to housing
projects for low to moderate income familities or notes secured by mortgages on
residences. Repayment of these bonds is dependent upon, among other things:
  - occupany levels;
  - rental income;
  - the default rate on the underlying mortgage loans;
  - the ability of mortgage insurers to pay claims;
  - the continued availability of federal, state or local housing subsidiary
    programs;
  - economic conditions in local markets;
  - construction costs;
  - taxes;
  - utility costs;
  - the level of operating expenses; and
  - the managerial ability of project managers.

Housing bonds generally may be prepaid at any time. Therefore, their average
life will ordinarily be less then their stated maturity.

Changes to the portfolio from bond redemptions, maturities and sales may affect
the Fund's concentrations over time.

STATE CONCENTRATION RISK

NEW YORK RISKS

GENERALLY

For decades, New York's economy has trailed the rest of the nation. Both the
state and New York City have experienced long-term structural imbalances between
revenues and expenses, and have repeatedly relied substantially on non-recurring
measures to achieve budget balance. The pressures that contribute to budgetary
problems at both the state and local level include:

                                       8
<PAGE>
  - the high combined state and local tax burden;

  - a decline in manufacturing jobs, leading to above-average unemployment;

  - sensitivity to the financial services industry; and

  - dependence on federal aid.

STATE GOVERNMENT

The State government frequently has difficulty approving budgets on time. Budget
gaps of $3 billion and $5 billion are projected for the next two years. The
State's general obligation bonds are rated A+ by Standard & Poor's and A2 by
Moody's. There is $37 billion of state-related debt outstanding.

NEW YORK CITY GOVERNMENT

Even though the City had budget surpluses each year from 1981, budget gaps of
over $2 billion are projected for the 2002, 2003 and 2004 fiscal years. New York
City faces fiscal pressures from:

  - aging public facilities that need repair or replacement;

  - welfare and medical costs;

  - expiring labor contracts; and

  - a high and increasing debt burden.

The City requires substantial state aid, and its fiscal strength depends heavily
on the securities industry. Its general obligation bonds are rated A- by
Standard & Poor's and A3 by Moody's. $31.2 billion of combined City, MAC and PBC
debt is outstanding, and the City proposes $25.3 billion of financing over
fiscal 1999-2003. New York City currently expects to reach its constitutional
limits on debt issuance in Fiscal 2003.

LITIGATION AND LEGISLATION RISKS

We do not know of any pending litigation that might have a material adverse
effect upon the Fund.

Future tax legislation could affect the value of the portfolio by:
  - limiting real property taxes,
  - reducing tax rates,
  - imposing a flat or other form of tax, or
  - exempting investment income from tax.

SELLING OR EXCHANGING UNITS

You can sell your units at any time for a price based on net asset value. Your
net asset value is calculated each business day by:
  - ADDING the value of the bonds, net accrued interest, cash and any other Fund
    assets;
  - SUBTRACTING accrued but unpaid Fund expenses, unreimbursed Trustee advances,
    cash held to buy back units or for distribution to investors and any other
    Fund liabilities; and
  - DIVIDING the result by the number of outstanding units.

Your net asset value when you sell may be more or less than your cost because of
sales fees, market movements and changes in the portfolio.

SPONSORS' SECONDARY MARKET

While we are not obligated to do so, we will buy back units at net asset value
without any other fee or charge. We may resell the units to other buyers or to
the Trustee. You should consult your financial professional for current

                                       9
<PAGE>
market prices to determine if other broker-dealers or banks are offering higher
prices.

We have maintained the secondary market continuously for over 28 years, but we
could discontinue it without prior notice for any business reason.

SELLING UNITS TO THE TRUSTEE

Regardless of whether we maintain a secondary market, you can sell your units to
the Trustee at any time by sending the Trustee a letter (with any outstanding
certificates if you hold Unit certificates). You must properly endorse your
certificates (or execute a written transfer instrument with signatures
guaranteed by an eligible institution). Sometimes, additional documents are
needed such as a trust document, certificate of corporate authority, certificate
of death or appointment as executor, administrator or guardian.

Within seven days after your request and the necessary documents are received,
the Trustee will mail a check to you. Contact the Trustee for additional
information.

As long as we are maintaining a secondary market, the Trustee will sell your
units to us at a price based on net asset value. If there is no secondary
market, the Trustee may sell your units in the over-the-counter market for a
higher price, but it is not obligated to do so. In that case, you will receive
the net proceeds of the sale.

If the Fund does not have cash available to pay you for units you are selling,
the agent for the Sponsors will select bonds to be sold. Bonds will be selected
based on market and credit factors. These sales could be made at times when the
bonds would not otherwise be sold and may result in your receiving less than the
unit par value and also reduce the size and diversity of the Fund.

There could be a delay in paying you for your units:
  - if the New York Stock Exchange is closed (other than customary weekend and
    holiday closings);
  - if the SEC determines that trading on the New York Stock Exchange is
    restricted or that an emergency exists making sale or evaluation of the
    bonds not reasonably practicable; and
  - for any other period permitted by SEC order.

EXCHANGE OPTION

You may exchange units of certain Defined Asset Funds for units of this Fund
with no sales fee. You may exchange units of this Fund for units of certain
other Defined Asset Funds at a reduced sales fee if your investment goals
change. To exchange units, you should talk to your financial professional about
what funds are exchangeable, suitable and currently available.

Normally, an exchange is taxable and you must recognize any gain or loss on the
exchange. However, the IRS may try to disallow a loss if the portfolios of the
two funds are not materially different; you should consult your own tax adviser.

We may amend or terminate this exchange option at any time without notice.

                                       10

HOW THE FUND WORKS

PRICING

The price of a unit includes interest accrued on the bonds, less expenses, from
the initial most recent Record Day up to, but not including, the settlement
date, which is usually three business days after the purchase date of the unit.

A portion of the price of a unit consists of cash so that the Trustee can
provide you with regular monthly income. When you sell your units you will
receive your share of this cash.

EVALUATIONS

An independent Evaluator values the bonds on each business day (excluding
Saturdays, Sundays and the following holidays as observed by the New York Stock
Exchange: New Year's Day, Presidents' Day, Martin Luther King, Jr. Day, Good
Friday, Memorial Day, Independence Day, Labor Day, Thanksgiving and Christmas).
Bond values are based on current bid or offer prices for the bonds or comparable
bonds. In the past, the difference between bid and offer prices of publicly
offered tax-exempt bonds has ranged from 0.5% of face amount on actively traded
issues to 3.5% on inactively traded issues; the difference has averaged between
1 and 2%.

INCOME

The Trustee credits interest to an Income Account and other receipts to a
Capital Account. The Trustee may establish a Reserve Account by withdrawing from
these accounts amounts it considers appropriate to pay any material liability.
These accounts do not bear interest.

PLACEMENT FEE

The Sponsors receive a quarterly placement fee from each Seller equal to an
annual percentage ranging from 0.487% to 0.75% of the outstanding principal
amount of bonds sold by that Seller and held by the Fund.

EXPENSES

The Trustee is paid monthly. It also benefits when it holds cash for the Fund in
non-interest bearing accounts. The Trustee may also receive additional amounts:
  - to reimburse the Trustee for the Fund's operating expenses;
  - for extraordinary services and costs of indemnifying the Trustee and the
    Sponsors;
  - costs of actions taken to protect the Fund and other legal fees and
    expenses;
  - expenses for keeping the Fund's registration statement current; and
  - Fund termination expenses and any governmental charges.

The Sponsors are currently reimbursed up to 55 CENTS per $1,000 face amount
annually for providing portfolio supervisory, bookkeeping and administrative
services and for any other expenses properly chargeable to the Fund. Legal,
typsesetting, electronic filing and regulatory filing fees and expenses
associated with updating the Fund's registration statement yearly are also now
chargeable to the Fund. While this fee may exceed the amount of these costs and
expenses attributable to this Fund, the total of these fees for all Series of
Defined Asset Funds will not exceed the aggregate amount attributable to all of
these Series for any calendar year. The Fund also pays the Evaluator's fees.

                                       11
<PAGE>
The Trustee's, Sponsors' and Evaluator's fees may be adjusted for inflation
without investors' approval.

The Sponsors will pay advertising and selling expenses at no charge to the Fund.
If Fund expenses exceed initial estimates, the Fund will owe the excess. The
Trustee has a lien on Fund assets to secure reimbursement of Fund expenses and
may sell bonds if cash is not available.

PORTFOLIO CHANGES

The Sponsors and Trustee are not liable for any default or defect in a bond; if
a contract to buy any bond.

Unlike a mutual fund, the portfolio is designed to remain intact and we may keep
bonds in the portfolio even if their credit quality declines or other adverse
financial circumstances occur. However, we may sell a bond in certain cases if
we believe that certain adverse credit conditions exist or if a bond becomes
taxable.

If we maintain a secondary market in units but are unable to sell the units that
we buy in the secondary market, we will redeem units, which may affect the
composition of the portfolio. Units offered in the secondary market may not
represent the same face amount of bonds that they did originally.

We decide whether or not to offer units for sale that we acquire in the
secondary market after reviewing:
  - diversity of the portfolio;
  - size of the Fund relative to its original size;
  - ratio of Fund expenses to income;
  - current and long-term returns;
  - degree to which units may be selling at a premium over par; and
  - cost of maintaining a current prospectus.

FUND TERMINATION

The Fund will terminate following the stated maturity or sale of the last bond
in the portfolio. The Fund may also terminate earlier with the consent of
investors holding 51% of the units or if total assets of the Fund have fallen
below 40% of the face amount of bonds deposited. We will decide whether to
terminate the Fund early based on the same factors used in deciding whether or
not to offer units in the secondary market.

When the Fund is about to terminate you will receive a notice, and you will be
unable to sell your units after that time. On or shortly before termination, we
will sell any remaining bonds, and you will receive your final distribution. Any
bond that cannot be sold at a reasonable price may continue to be held by the
Trustee in a liquidating trust pending its final sale.

You will pay your share of the expenses associated with termination, including
brokerage costs in selling bonds. This may reduce the amount you receive as your
final distribution.

CERTIFICATES

Certificates for units are issued on request. You may transfer certificates by
complying with the requirements for redeeming certificates, described above. You
can replace lost or mutilated certificates by delivering satisfactory indemnity
and paying the associated costs.

                                       12
<PAGE>
TRUST INDENTURE

The Fund is a 'unit investment trust' governed by a Trust Indenture, a contract
among the Sponsors, the Trustee and the Evaluator, which sets forth their duties
and obligations and your rights. A copy of the Indenture is available to you on
request to the Trustee. The following summarizes certain provisions of the
Indenture.

The Sponsors and the Trustee may amend the Indenture without your consent:
  - to cure ambiguities;
  - to correct or supplement any defective or inconsistent provision;
  - to make any amendment required by any governmental agency; or
  - to make other changes determined not to be materially adverse to your best
    interest (as determined by the Sponsors).
Investors holding 51% of the units may amend the Indenture. Every investor must
consent to any amendment that changes the 51% requirement. No amendment may
reduce your interest in the Fund without your written consent.

The Trustee may resign by notifying the Sponsors. The Sponsors may remove the
Trustee without your consent if:
  - it fails to perform its duties and the Sponsors determine that its
    replacement is in your best interest; or
  - it becomes incapable of acting or bankrupt or its affairs are taken over by
    public authorities.
Investors holding 51% of the units may remove the Trustee. The Evaluator may
resign or be removed by the Sponsors and the Trustee without the consent of
investors. The resignation or removal of either becomes effective when a
successor accepts appointment. The Sponsors will try to appoint a successor
promptly; however, if no successor has accepted within 30 days after notice of
resignation, the resigning Trustee or Evaluator may petition a court to appoint
a successor.

Any Sponsor may resign as long as one Sponsor with a net worth of $2 million
remains and agrees to the resignation. The remaining Sponsors and the Trustee
may appoint a replacement. If there is only one Sponsor and it fails to perform
its duties or becomes bankrupt the Trustee may:
  - remove it and appoint a replacement Sponsor;
  - liquidate the Fund; or
  - continue to act as Trustee without a Sponsor.

Merrill Lynch, Pierce, Fenner & Smith Incorporated acts as agent for the
Sponsors.

The Trust Indenture contains customary provisions limiting the liability of the
Trustee, the Sponsors and the Evaluator.

LEGAL OPINION

Davis Polk & Wardwell, 450 Lexington Avenue, New York, New York 10017, as
counsel for the Sponsors, has given an opinion that the units are validly
issued. Special counsel located in the relevant states have given state and
local tax opinions.

Each Sponsor is a Delaware corporation and it, or its predecessor, has acted as
sponsor to many unit investment trusts. As a registered broker-dealer each
Sponsor buys and sells securities (including investment company shares) for
others (including investment companies) and participates as an underwriter in
various selling groups.

TRUSTEE

The Bank of New York, 101 Barclay Street, 17 W, New York, New York 10268, is the
Trustee. It is supervised by the Federal Deposit Insurance Corporation, the
Board of Governors of the Federal Reserve System and New York State banking
authorities.

UNDERWRITERS' AND SPONSORS' PROFITS

Underwriters receive sales charges when they sell units. The Sponsors also
realized a profit or loss on the initial date of deposit of the bonds. Any cash
made available by you to the Sponsors before the settlement date for those units
may be used in the Sponsors' businesses to the extent permitted by federal law
and may benefit the Sponsors.

A Sponsor or Underwriter may realize profits or sustain losses on bonds in the
Fund which were acquired from underwriting syndicates of which it was a member.

In maintaining a secondary market, the Sponsors will also realize profits or
sustain losses in the amount of any difference between the prices at which they
buy units and the prices at which they resell or redeem them.

PUBLIC DISTRIBUTION

The Sponsors do not intend to qualify units for sale in any foreign countries.
This prospectus does not constitute an offer to sell units in any country where
units cannot lawfully be sold.

CODE OF ETHICS

The Fund and the Agent for the Sponsors have each adopted a code of ethics
requiring reporting of personal securities transactions by its employees with
access to information on Fund transactions. Subject to certain conditions, the
codes permit employees to invest in Fund securities for their own accounts. The
codes are designed to prevent fraud, deception and misconduct against the Fund
and to provide reasonable standards of conduct. These codes are on file with the
Commission and you may obtain a copy by

                                       14

prospectus.

YEAR 2000 ISSUES

Many computer systems were designed in such a way that they may be unable to
distinguish between the year 2000 and the year 1900 (commonly known as the "Year
2000 Problem"). To date we are not aware of any major operational difficulties
resulting from the computer system changes necessary to prepare for the Year
2000. However, there can be no assurance that the Year 2000 Problem will not
adversely affect the issuers of the bonds contained in the Portfolio. We cannot
predict whether any impact will be material to the Fund as a whole.

TAXES

The following summary describes some of the important income tax consequences of
holding units. It assumes that you are not a dealer in securities, financial
institution, insurance company or other investor with special circumstances or
subject to special rules. You should consult your own tax adviser about your
particular circumstances.

At the date of issue of each bond, counsel for the issuer delivered an opinion
to the effect that interest on the bond is exempt from regular federal income
tax. However, interest may be subject to state and local taxes and may be taken
into consideration in determining your preference items for alternative minimum
tax purposes. Neither we nor our counsel have reviewed the issuance of the
bonds, related proceedings or the basis for the opinions of counsel for the
issuers. We cannot assure you that the issuers (or other users) have complied or
will comply with any requirements necessary for a bond to be tax-exempt. If any
of the bonds were determined not to be tax-exempt, you could be required to pay
income tax for current and prior years, and if the Fund were to sell the bond,
it might have to sell it at a substantial discount.

In the opinion of our counsel, under existing law:

GENERAL TREATMENT OF THE FUND AND YOUR INVESTMENT

The Fund will not be taxed as a corporation for federal income tax purposes, and
you will be considered to own directly your share of each bond in the Fund.

Our counsel is of the opinion that the Fund (and therefore the investors, as
discussed below) will be treated as owning the bonds, notwithstanding the
Sellers' repurchase commitments. However, because there are no regulations,
published rulings or judicial decisions that characterize for federal income tax
purposes repurchase commitments like the Sellers' with respect to the bonds, it
is not certain that the IRS will agree with the conclusions of our counsel.
Therefore, it is possible that the IRS may take actions that might result in the
Fund (and therefore the investors) not being treated as owning the bonds for
federal income tax purposes.

GAIN OR LOSS UPON DISPOSITION

When all or part of your share of a bond is disposed of (for example, when the
Fund sells, exchanges or redeems a bond or when you sell or exchange your
units), you will generally recognize capital gain or loss. While not free from
doubt, the opinion of our counsel is that any capital gain or loss derived from
the Fund

                                       15
<PAGE>
will be short-term capital gain or loss regardless of the time that you have
held your Units.

YOUR BASIS IN THE BONDS

You may be required to allocate a portion of your cost for your Units to the
Sellers' repurchase commitment with respect to the bonds. When all or part of
your pro rata portion of a bond is disposed of (and the commitment with respect
to that bond simultaneously is disposed of, lapses or is exercised), both your
basis in your pro rata portion of the bond and your basis in your pro rata
portion of the commitment will be taken into account in determining your overall
net income or loss from the disposition. In some cases, this overall net income
or loss may consist of ordinary income attributable to market discount on the
pro rata portion of the bond and of capital loss attributable to the commitment.
The deductibility of capital losses is subject to limitations. You should
consult your tax adviser in this regard.

If your basis for your pro rata portion of a bond (after giving effect to any
required allocation to the commitment) exceeds the redemption price at maturity
of that bond, you may be considered to have purchased your pro rata portion of
the bond at a 'bond premium,' which must be amortized.

EXPENSES

If you are not a corporate investor, you will not be entitled to a deduction for
your share of fees and expenses of the Fund. Also, if you borrowed money in
order to purchase or carry your units, you will not be able to deduct the
interest on this borrowing for federal income tax purposes. The IRS may treat
your purchase of units as made with borrowed money even if the money is not
directly traceable to the purchase of units.

STATE AND LOCAL TAXES

Under the income tax laws of the State and City of New York, the Fund will not
be taxed as a corporation. If you are a New York taxpayer, your income from the
Fund will not be tax-exempt in New York except to the extent that the income is
earned on bonds that are tax-exempt for New York purposes. Depending on where
you live, your income from the Fund may be subject to state and local taxation.
You should consult your tax adviser in this regard.

SUPPLEMENTAL INFORMATION

You can receive at no cost supplemental information about the Fund by calling
the Trustee. The supplemental information includes more detailed risk disclosure
about the types of bonds that may be in the Fund's portfolios, general risk
disclosure concerning any insurance securing certain bonds, and general
information about the structure and operation of the Fund. The supplemental
information is also available from the SEC.

DEFINED ASSET FUNDS - MUNICIPAL INVESTMENT TRUST FUND,
NEW YORK PUT SERIES - 1

NOTES TO PORTFOLIO
AS OF MARCH 31, 2000

   (1) The ratings of the bonds are by Standard & Poor's Ratings
       Group, or by Moody's Investors Service, Inc. if followed by
       "(m)", or by Fitch Investors Service, Inc. if followed by
       "(f)"; "NR" indicates that this bond is not currently rated by
       any of the above-mentioned rating services. These ratings have
       been furnished by the Evaluator but not confirmed with
       the rating agencies.

   (2) Securities may be redeemed prior to maturity either by a
       partial scheduled redemption pursuant to a sinking fund or by
       a refunding redemption pursuant to which, at the option of the
       issuer, all or part of the issue can be retired from any
       available funds, at prices which may or may not include a
       premium.

   (3) See Notes to Financial Statements.

   (4) All securities in the Fund have been purchased from savings banks or
       savings and loan associations (the "Sellers"), each of which has
       committed to repurchase any security sold by it to the Fund upon the
       occurrence of certain events. Any repurchase is at a price not less
       than the original purchase price to the fund of the security plus
       interest accrued to the date of repurchase. Commitments are backed by
       collateral.

       There is no assurance as to the continuing ability of Issuers of
       the securities to meet their principal and interest requirements.
       Additionally, if a receiver or conservator is appointed for a seller,
       recent changes in Federal law may permit Federal banking regulators
       to refuse to honor the Seller's repurchase commitments and Holders
       could be left without the full protections afforded by the collateral.
       In that case, the liquidity of the Fund's portfolio could be impaired.

   (5) The Trustee will cause the Seller to purchase each security at
       its Put Price on the Disposition Date specified unless on or before
       this date it can be sold, in the opinion of the Sponsor, for a net
       amount in excess of its Put Price.
