RISK/RETURN SUMMARY
1. WHAT IS THE FUND'S OBJECTIVE?
The Fund seeks interest income that is exempt from regular
federal income taxes by investing in a fixed portfolio
consisting primarily of municipal revenue bonds with an
estimated average life of 9 years.
2. WHAT ARE MUNICIPAL REVENUE BONDS?
Municipal 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 airports, health care
facilities, housing and municipal electric, water and sewer
utilities. Generally, payments on these bonds depend solely
on the revenues generated by the projects, excise taxes or
state appropriations, and are not backed by the
government's taxing power.
3. WHAT IS THE FUND'S INVESTMENT STRATEGY?
O The Fund plans to hold to maturity 15 intermediate term
tax-exempt municipal bonds, including some short-term bonds
reserved to pay the defined sales fee, with a current
aggregate face amount of $9,845,000.
o The Fund is a unit investment trust which means that,
unlike a mutual fund, the Fund's portfolio is not managed.
o When the bonds were initially deposited (November 21,
1997), they were rated A or better by Standard & Poor's,
Moody's or Fitch, or in the opinion of the agent for the
Sponsors had similar credit quality to bonds rated A or
better. The credit quality of the bonds may currently be
lower.
o Many of the bonds can be called at a premium declining over
time to par value. Some bonds may be called earlier at par
for extraordinary reasons.
o 26% of the bonds are backed by bank letters of credit.
o 12% of the bonds are insured by insurance companies.
Letters of credit and insurance guarantee timely payments
of principal and interest on the bonds (but not Fund units
or the market value of the bonds before they mature).
The Portfolio consists of municipal bonds of the following
types:
APPROXIMATE
PORTFOLIO
PERCENTAGE
o Airports/Ports/Highways 3%
o General Obligation 6%
o Hospitals/Health Care 15%
o Housing 14%
o Industrial Development Revenue 25%
o Lease Rental Appropriation 3%
o Refunded Bonds 13%
o Solid Waste Disposal 7%
o Universities/Colleges 14%
4. WHAT ARE THE SIGNIFICANT RISKS?
YOU CAN LOSE MONEY BY INVESTING IN THE FUND. THIS CAN
HAPPEN FOR VARIOUS REASONS, INCLUDING:
o Rising interest rates, an issuer's worsening financial
condition or a drop in bond ratings can reduce the price of
your units.
o Because the Fund is concentrated in industrial development
revenue bonds, adverse developments in this sector may
affect the value of your units.
o 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.
o The Fund will receive early returns of principal 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.
5. IS THIS FUND APPROPRIATE FOR YOU?
Yes, if you want monthly income free from regular federal
income tax. You will benefit from a professionally selected
and supervised portfolio whose risk is reduced by investing
in bonds of several different issuers.
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, if you are subject to AMT or if you cannot
tolerate any risk.

7. HOW HAVE SIMILAR FUNDS PERFORMED IN THE PAST?
In the following chart we show past performance of prior
Intermediate Series, which had the same investment
objectives, strategies and types of bonds as this Fund.
These prior Intermediate Series were offered between August
9, 1988 and October 18, 1996 and were outstanding on
September 30, 1998. OF COURSE, PAST PERFORMANCE OF PRIOR
SERIES IS NO GUARANTEE OF FUTURE RESULTS OF THIS FUND.

Note: All returns represent changes in unit price with distributions reinvested
into the Municipal Fund Investment Accumulation Program.
8. 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.
9. 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.
4
<PAGE>
UNIT PRICE PER UNIT $1,048.10
(as of October 31, 1998)
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.
10. 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, less any remaining deferred
sales fee. You will not pay any other fee
when you sell your units.
11. 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.
Interest on approximately 39% of the bonds will be a
preference item for Alternative Minimum Tax. A portion of
the income may also be exempt from state and local personal
income taxes, depending on where you live.
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.
12. WHAT OTHER SERVICES ARE AVAILABLE?
REINVESTMENT
You will receive your monthly income in cash unless you
choose to compound your income by reinvesting with 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
You may exchange units of this Fund for 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 exchanges.

To compare the yield of a taxable security with the yield of a federally
tax-free security, find your taxable income and read across. The table
incorporates 1999 federal income tax rates and assumes that all income would
otherwise be taxed at a U.S. 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, the possible partial disallowance of deductions
or state and local taxation. Consequently, investors are urged to consult their
own tax advisors in this regard.

NOTES:
+ Regular taxable income plus state income
taxes and personal exemptions.
++ Assuming no dependents.
Under federal tax law, interest income on certain municipal bonds, although
exempt from regular income tax, is treated as a 'preference' item for purposes
of AMT. The table above shows amounts of such municipal bond 'preference'
interest income, assuming no other 'preference' or similar items apply, that
individual taxpayers could receive in 1999 without becoming subject to the AMT.
The table gives information for single and joint returns of U.S. individuals
having no dependents. The table provides three income levels and three
hypothetical state income tax rates. The table further assumes that the stated
amount of municipal bond 'preference' interest income is subject to state income
taxes.

<PAGE>
WHAT YOU CAN EXPECT FROM YOUR INVESTMENT
MONTHLY INCOME
The Fund will pay you regular monthly income. Your monthly income may vary
because of:
o elimination of one or more bonds from the Fund's portfolio because of
calls, redemptions or sales;
o a change in the Fund's expenses; or
o the failure by a bond's issuer to pay interest.
Changes in interest rates generally will not affect your monthly income because
the portfolio is fixed.
Along with your monthly 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):
Estimated Annual Estimated
Interest Income - Annual Expenses
- -------------------------------------------------
Unit Price
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:
o a monthly statement of income payments and any principal payments;
o a notice from the Trustee when new bonds are deposited in exchange or
substitution for bonds originally deposited;
o an annual report on Fund activity; and
o 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:
o copies of bond evaluations to enable you to comply with federal and state tax
reporting requirements; and
o audited financial statements of the Fund.
You may inspect records of Fund transactions at the Trustee's office during
regular business hours.
7
<PAGE>
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
Many bonds can be prepaid or 'called' by the issuer before their stated
maturity. For example, some bonds may be required to be called pursuant to
mandatory sinking fund provisions.
Also, an issuer might call its bonds during periods of falling interest rates,
if the issuer's bonds have a coupon higher than current market rates.
An issuer might call its bonds in extraordinary cases, including if:
o it no longer needs the money for the original purpose;
o the project is condemned or sold;
o the project is destroyed and insurance proceeds are used to redeem the
bonds;
o any related credit support expires and is not replaced; or
o interest on the bonds become taxable.
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
The bonds will generally trade in the over-the-counter market. We cannot assure
you that a liquid trading market will exist, especially since current law may
restrict the Fund from selling bonds to any Sponsor. The value of the bonds, and
of your investment, may be reduced if trading in bonds is limited or absent.
CONCENTRATION RISK
When a certain type of bond makes up 25% or more of the portfolio, the Fund is
said to be 'concentrated' in that bond type, which makes the Fund less
diversified.
Here is what you should know about the Fund's concentration in industrial
development revenue bonds (IDRs). IDRs are issued to finance various privately
operated projects such as pollution control and manufacturing facilities.
Payment for these bonds depends on:
o creditworthiness of the corporate operator of the project being financed;
o economic factors relating to the particular industry; and,
o in some cases, creditworthiness of an affiliated or third-party guarantor.
Changes to the portfolio from bond redemptions, maturities and sales may affect
the Fund's concentration over time.
BOND QUALITY RISK
A reduction in a bond's rating may decrease its value and, indirectly, the value
of your investment in the Fund.
8
<PAGE>
INSURANCE RELATED RISK
Some bonds may be backed by insurance companies (as shown under Portfolio).
Insurance policies generally make payments only according to a bond's original
payment schedule and do not make early payments when a bond defaults or becomes
taxable. Although the federal government does not regulate the insurance
business, various state laws and federal initiatives and tax law changes could
significantly affect the insurance business. The claims-paying ability of the
insurance companies is generally rated A or better by Standard & Poor's or
another nationally recognized rating organization. The insurance company ratings
are subject to change at any time at the discretion of the rating agencies.
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:
o limiting real property taxes,
o reducing tax rates,
o imposing a flat or other form of tax, or
o 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:
o adding the value of the bonds, net accrued interest, cash and any other
Fund assets;
o 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
o 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.
If you sell your units before the final deferred sales fee installment, the
amount of any remaining installments will be deducted from your proceeds.
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 other than any remaining deferred sales charge.
We may resell the units to other buyers or to the Trustee. You should consult
your financial professional for current market prices to determine if other
broker-dealers or banks are offering higher prices.
We have maintained a secondary market continuously for over 25 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
9
<PAGE>
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.
If you acquire 25% or more of the outstanding units of the Fund and you sell
units with a value exceeding $250,000, the Trustee may choose to pay you 'in
kind' by distributing bonds and cash with a total value equal to the price of
those units. The Trustee will try to distribute bonds in the portfolio pro rata,
but it reserves the right to distribute only one or a few bonds. The Trustee
will act as your agent in an in kind distribution and will either hold the bonds
for your account or sell them as you instruct. You must pay any transaction
costs as well as transfer and ongoing custodial fees on sales of bonds
distributed in kind.
There could be a delay in paying you for your units:
o if the New York Stock Exchange is closed (other than customary weekend and
holiday closings);
o 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
o for any other period permitted by SEC order.
EXCHANGE OPTION
You may exchange units of certain Defined Asset Funds for units of this Fund at
a maximum exchange fee of 1.75%. You may exchange units of this Fund for units
of certain other 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.
HOW THE FUND WORKS
PRICING
The price of a unit includes interest accrued on the bonds, less expenses, from
the 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.
In addition, as with mutual funds, the Fund (and therefore the investors) pay
all or some of the costs of organizing the Fund including:
o cost of initial preparation of legal documents;
o federal and state registration fees;
o initial fees and expenses of the Trustee;
o initial audit; and
o legal expenses and other out-of-pocket expenses.
10
<PAGE>
These costs are amortized over the first five years of the Fund.
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.
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:
o to reimburse the Trustee for the Fund's operating expenses;
o for extraordinary services and costs of indemnifying the Trustee and the
Sponsors;
o costs of actions taken to protect the Fund and other legal fees and
expenses;
o expenses for keeping the Fund's registration statement current; and
o Fund termination expenses and any governmental charges.
The Sponsors are currently reimbursed up to 45 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. 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.
Any quarterly deferred sales charges you owe are paid with interest and
principal from certain bonds. If these amounts are not enough, the rest will be
paid out of distributions to you from the Fund's Capital and Income Accounts.
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.
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.
11
<PAGE>
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 will affect the size
and 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:
o diversity of the portfolio;
o size of the Fund relative to its original size;
o ratio of Fund expenses to income;
o current and long-term returns;
o degree to which units may be selling at a premium over par; and
o 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.
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:
o to cure ambiguities;
o to correct or supplement any defective or inconsistent provision;
o to make any amendment required by any governmental agency; or
o 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:
o it fails to perform its duties and the Sponsors determine that its
replacement is in your best interest; or
o it becomes incapable of acting or bankrupt or its affairs are taken over by
public authorities.
12
<PAGE>
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:
o remove it and appoint a replacement Sponsor;
o liquidate the Fund; or
o 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
special counsel for the Sponsors, has given an opinion that the units are
validly issued.
AUDITORS
Deloitte & Touche LLP, 2 World Financial Center, New York, New York 10281,
independent accountants, audited the Statement of Condition included in this
prospectus.
SPONSORS
The Sponsors are:
MERRILL LYNCH, PIERCE, FENNER & SMITH INCORPORATED (a wholly-owned subsidiary of
Merrill Lynch & Co., Inc.)
P.O. Box 9051,
Princeton, NJ 08543-9051

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.
13
<PAGE>
UNDERWRITERS' AND SPONSORS' PROFITS
Underwriters receive sales charges when they sell units. The Sponsors also
realized a profit or loss on the initial 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
Merrill Lynch, as agent for the Sponsors, has adopted a code of ethics requiring
preclearance and reporting of personal securities transactions by its employees
with access to information on portfolio transactions. The goal of the code is to
prevent fraud, deception or misconduct against the Fund and to provide
reasonable standards of conduct.
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'). We do not expect that the computer system changes necessary to
prepare for the Year 2000 will cause any major operational difficulties for the
Fund.
TAXES
The following summary describes some of the important income tax consequences of
holding units. It assumes that you are not a dealer, financial institution,
insurance company or other investor with special circumstances. 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 federal
alternative minimum tax. 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 issuer (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.
INCOME 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
14
<PAGE>
or exchange your units), you will generally recognize capital gain or loss. Your
gain, however, will generally be ordinary income to the extent of any accrued
'market discount'. Generally you will have market discount to the extent that
your basis in a bond when you purchase a unit is less than its stated redemption
price at maturity (or, if it is an original issue discount bond, the issue price
increased by original issue discount that has accrued on the bond before your
purchase). You should consult your tax adviser in this regard.
If your net long-term capital gains exceed your net short-term capital losses,
the excess may be subject to tax at a lower rate than ordinary income. Any
capital gain from the Fund will be long-term if you are considered to have held
your investment on each bond for more than one year and short-term if you held
it for one year or less. If you are an individual and sell your units after
holding them for more than one year, you may be entitled to a 20% maximum
federal tax rate on any resulting gains. Consult your tax adviser in this
regard. Because the deductibility of capital losses is subject to limitations,
you may not be able to deduct all of your capital losses.
YOUR BASIS IN THE BONDS
Your aggregate basis in the bonds will be equal to the cost of your units,
including any sales charges and the organizational expenses you pay, adjusted to
reflect any accruals of 'original issue discount,' 'acquisition premium' and
'bond premium'. You should consult your tax adviser in this regard.
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 portfolio, 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.

or in part, are initially at prices of par plus a premium, then
subsequently at prices declining to par. Certain securities may
provide for redemption at par prior or in addition to any
optional or mandatory redemption dates or maturity, for
example, through the operation of a maintenance and replacement
fund, if proceeds are not able to be used as contemplated, the
project is condemned or sold or the project is destroyed and
insurance proceeds are used to redeem the securities. Many of
the securities are also subject to mandatory sinking fund
redemption commencing on dates which may be prior to the date
on which securities may be optionally redeemed. Sinking fund
redemptions are at par and redeem only part of the issue. Some
of the securities have mandatory sinking funds which contain
optional provisions permitting the issuer to increase the
principal amount of securities called on a mandatory redemption
date. The sinking fund redemptions with optional provisions
may, and optional refunding redemptions generally will, occur
at times when the redeemed securities have an offering side
evaluation which represents a premium over par. To the extent
that the securities were acquired at a price higher than the
redemption price, this will represent a loss of capital when
compared with the Public Offering Price of the Units when
acquired. Distributions will generally be reduced by the amount
of the income which would otherwise have been paid with respect
to redeemed securities and there will be distributed to Holders
any principal amount and premium received on such redemption
after satisfying any redemption requests for Units received by
the Fund. The estimated current return may be affected by
redemptions. The tax effect on Holders of redemptions and
related distributions is described under "Taxes" in this
Prospectus, Part B.
(4) Securities that are tax preference items for purposes of the
Alternative Minimum Tax are indicated by "(AMT)". See "Taxes"
in this Prospectus, Part B.
