CALIFORNIA INSURED PORTFOLIO--RISK/RETURN SUMMARY


       1.  WHAT IS THE FUND'S OBJECTIVE?
           The Fund seeks interest income that is exempt from regular
           federal income taxes and some state and local taxes by
           investing in a fixed portfolio consisting primarily of
           insured, long-term municipal revenue bonds.
       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 9 long-term tax-exempt
           municipal bonds, and some short-term bonds reserved to pay
           the deferred sales fee, with an aggregate face amount of
           $4,925,000.
        o  The Fund is a unit investment trust which means that,
           unlike a mutual fund, the Portfolio is not managed.
        o  The bonds are rated AAA or Aaa by Standard & Poor's,
           Moody's or Fitch.
        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  100% of the bonds are insured by insurance companies that
           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



/ / General Obligation                                 15%
/ / Hospital/Health Care                               11%
/ / Municipal Water/Sewer Utilities                    1%
/ / Refunded Bonds                                     15%
/ / Special Tax                                        43%
/ / Universities/Colleges                              15%



       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 special tax 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.

           ALSO, THE PORTFOLIO IS CONCENTRATED IN BONDS OF CALIFORNIA
           SO IT IS LESS DIVERSIFIED THAN A NATIONAL FUND AND IS
           SUBJECT TO RISKS PARTICULAR TO CALIFORNIA 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 insured
           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 or if you cannot tolerate any risk.


           DEFINING YOUR INCOME


           WHAT YOU MAY EXPECT (Payable on the 25th day of
           the month to holders of record on the 10th day
           of the month):
           Regular Monthly Income per unit                           $    4.43
           Annual Income per unit:                           $   53.19
           These figures are estimates determined on the evaluation
           day; actual payments may vary.



       6.  WHAT ARE THE FUND'S FEES AND EXPENSES?

           directly or indirectly, when you invest in the Fund.

           The Sponsors historically paid organization costs and

       7.  HOW HAVE SIMILAR FUNDS PERFORMED IN THE PAST?
           In the following chart we show past performance of prior
           California Portfolios, which had investment objectives,
           strategies and types of bonds substantially similar to
           this Fund. These prior Series differed in that they
           charged a higher sales fee. These prior California Series
           were offered between June 22, 1988 and September 27, 1996
           and were outstanding on March 31, 1999. OF COURSE, PAST
           PERFORMANCE OF PRIOR SERIES IS NO GUARANTEE OF FUTURE
           RESULTS OF THIS FUND.

       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.
           UNIT PRICE PER UNIT                     $1,094.22
           (as of February 28, 1999)
           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. Your income may also be
           exempt from some California state and local personal income
           taxes if you live in California.
           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 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, but the bonds will generally not be
           insured. 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.

NEW YORK PORTFOLIO--RISK/RETURN SUMMARY


       1.  WHAT IS THE FUND'S OBJECTIVE?
           The Fund seeks interest income that is exempt from regular
           federal income taxes and some state and local taxes by
           investing in a fixed portfolio consisting primarily of
           long-term municipal revenue bonds.
       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 10 long-term tax-exempt
           municipal bonds, and some short-term bonds reserved to pay
           the deferred sales fee, with an aggregate face amount of
           $4,420,000.
        o  The Fund is a unit investment trust which means that,
           unlike a mutual fund, the Portfolio is not managed.
        o  When the bonds were initially deposited they were rated A
           or better by Standard & Poor's, Moody's or Fitch. The
           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.

           The Portfolio consists of municipal bonds of the following
           types:



                                                  APPROXIMATE
                                                   PORTFOLIO
                                                   PERCENTAGE
/ / General Obligation                                 2%
/ / Hospital/Health Care                              30%
/ / Housing                                           16%
/ / Lease Rental Appropriation                        17%
/ / Municipal Water/Sewer Utilities                   16%
/ / Special Tax                                        3%
/ / Universities/Colleges                             16%



       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 hospital/health care
           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.


                                       6
<PAGE>


           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 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 or if you cannot tolerate any risk.


           DEFINING YOUR INCOME


           WHAT YOU MAY EXPECT (Payable on the 25th day of
           the month to holders of record on the 10th day

           Regular Monthly Income per unit                           $    4.47
           Annual Income per unit:                           $   53.74
           These figures are estimates determined on the evaluation
           day; actual payments may vary.



       6.  WHAT ARE THE FUND'S FEES AND EXPENSES?

           In the following chart we show past performance of prior
           New York Portfolios, which had investment objectives,
           strategies and types of bonds substantially similar to
           this Fund. These prior Series differed in that they
           charged a higher sales fee. These prior New York Series
           were offered between January 14, 1988 and October 16, 1996
           and were outstanding on March 31, 1999. OF COURSE, PAST
           PERFORMANCE OF PRIOR SERIES IS NO GUARANTEE OF FUTURE

OHIO INSURED PORTFOLIO--RISK/RETURN SUMMARY


       1.  WHAT IS THE FUND'S OBJECTIVE?
           The Fund seeks interest income that is exempt from regular
           federal income taxes and some state and local taxes by
           investing in a fixed portfolio consisting primarily of
           insured, long-term municipal revenue bonds.
       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 10 long-term tax-exempt
           municipal bonds, and some short-term bonds reserved to pay
           the deferred sales fee, with an aggregate face amount of
           $3,230,000.
        o  The Fund is a unit investment trust which means that,
           unlike a mutual fund, the Portfolio is not managed.
        o  The bonds are rated AAA or Aaa by Standard & Poor's,
           Moody's or Fitch.
        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  100% of the bonds are insured by insurance companies that
           guarantee timely payments of principal and interest on the
           bonds (but not Fund units or the market value of the bonds
           before they mature).

       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 hospital/health care
           and university/college bonds, adverse developments in these
           sectors 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.

           ALSO, THE PORTFOLIO IS CONCENTRATED IN BONDS OF OHIO SO IT
           IS LESS DIVERSIFIED THAN A NATIONAL FUND AND IS SUBJECT TO
           RISKS PARTICULAR TO OHIO 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 insured
           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 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
           Ohio Portfolios, which had investment objectives,
           strategies and types of bonds substantially similar to
           this Fund. These prior Series differed in that they
           charged a higher sales fee. These prior Ohio Series were
           offered between September 22, 1988 and September 13, 1996
           and were outstanding on March 31, 1999. 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.
           UNIT PRICE PER UNIT                     $1,162.98
           (as of February 28, 1999)
           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. Your income may also be
           exempt from some Ohio state and local personal income taxes
           if you live in Ohio.
           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 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
           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.

PENNSYLVANIA INSURED PORTFOLIO--RISK/RETURN SUMMARY


       1.  WHAT IS THE FUND'S OBJECTIVE?
           The Fund seeks interest income that is exempt from regular
           federal income taxes and some state and local taxes by
           investing in a fixed portfolio consisting primarily of
           insured, long-term municipal revenue bonds.
       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 9 long-term tax-exempt
           municipal bonds, and some short-term bonds reserved to pay
           the deferred sales fee, with an aggregate face amount of
           $3,745,000.
        o  The Fund is a unit investment trust which means that,
           unlike a mutual fund, the Portfolio is not managed.
        o  The bonds are rated AAA or Aaa by Standard & Poor's,
           Moody's or Fitch.
        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  The Fund is concentrated in refunded bonds.
        o  100% of the bonds are insured by insurance companies that
           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

/ / Hospital/Health Care                               32%
/ / Miscellaneous                                      15%
/ / Refunded Bonds                                     42%



       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 hospital/health care
           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.

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

       7.  HOW HAVE SIMILAR FUNDS PERFORMED IN THE PAST?
           In the following chart we show past performance of prior
           Pennsylvania Portfolios, which had investment objectives,
           strategies and types of bonds substantially similar to
           this Fund. These prior Series differed in that they
           charged a higher sales fee. These prior Pennsylvania
           Series were offered between May 19, 1988 and September 13,
           1996 and were outstanding on March 31, 1999. OF COURSE,
           PAST PERFORMANCE OF PRIOR SERIES IS NO GUARANTEE OF FUTURE
           RESULTS OF THIS FUND.

       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.
           UNIT PRICE PER UNIT                     $1,092.46
           (as of February 28, 1999)
           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. Your income may also be
           exempt from some Pennsylvania state and local personal
           income taxes if you live in Pennsylvania.
           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 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, but the bonds generally will not be
           insured. 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.

</TABLE>


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 1999
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:
   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 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):


 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.

                                       16

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

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.

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 California Portfolio's concentration in
special tax bonds. Special tax bonds are payable from and secured by the
revenues a municipality derives from a particular tax; for example, a tax on
hotel rentals, on the purchase of food and beverages, car rentals, or liquor
consumption. These bonds are not secured by general tax revenues. Payment on
these bonds may be adversely affected by:
   o a reduction in revenues resulting from a decline in the local economy or
      population; or
   o a decline in the consumption, use or cost of the goods and services that
     are subject to taxation.

Here is what you should know about the New York, Ohio and Pennsylvania
Portfolios' concentrations in hospital and health care bonds.

                                       17
<PAGE>
   o payment for these bonds depends on revenues from private third-party payors
      and government programs, including Medicare and Medicaid, which have
      generally undertaken cost containment measures to limit payments to health
     care providers;
   o hospitals face increasing competition resulting from hospital mergers and
      affiliations;
   o hospitals need to reduce costs as HMOs increase market penetration and
     hospital supply and drug companies raise prices;
   o hospitals and health care providers are subject to various legal claims by
     patients and others and are adversely affected by increasing costs of
     insurance; and
   o 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;
   o 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; and
   o 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 Ohio Portfolio's concentration in
university/college bonds. Payment for these bonds depends on:
   o level or amount and diversity of sources of revenue;
   o availability of endowments and other funds;
   o enrollment;
   o financial management;
   o reputation; and
   o for public institutions, the financial condition of the government and its
      educational policies.

Here is what you should know about the Pennsylvania Portfolio's concentration in
refunded bonds. Refunded bonds are typically:
   o backed by direct obligations of the U.S. government; or
   o in some cases, backed by obligations guaranteed by the U.S. government and
      placed in escrow with an independent trustee;
   o noncallable prior to maturity; but
   o sometimes called for redemption prior to maturity.

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

STATE CONCENTRATION RISK

CALIFORNIA RISKS

Generally

From the late 1980s through the early 1990s, an economic recession eroded
California's revenue base. At the same time rapid population growth caused State
expenditures to exceed budget appropriations.

   o As a result California experienced a period of sustained budget imbalance.

   o Since that time the California economy has improved markedly and the
     extreme budgetary pressures have begun to lessen. However, the Asian
     economic crisis is expected to continue to have some negative effect on the
     State's economy.

State Government

The 1997-98 Budget Act allocated a State budget of approximately $66.9 Billion
and

                                       18
<PAGE>
contains no tax increases or reductions. Despite this somewhat improved state,
California's budget is still subject to certain unforeseeable events. For
example:

   o In December, 1994, Orange County and its investment pool filed for
     bankruptcy. While a settlement has been reached, the full impact on the
     State and Orange County is still unknown.

   o California faces constant fluctuations in other expenses (including health
     and welfare caseloads, property tax receipts, federal funding and natural
     disaster relief) that will undoubtedly create new budgetary pressure and
     reduce ability to pay their debts.

   o California's general obligation bonds are currently rated AA3 by Moody's
     and A+ by Standard & Poor's.

Other Risks

Issuers' ability to make payments on bonds (and the remedies available to
bondholders) could also be adversely affected by the following constraints:

   o Certain provisions of California's Constitution, laws and regulatory system
      contain tax, spending and appropriations limits and prohibit certain new
     taxes.

   o Certain other California laws subject the users of bond proceeds to strict
     rules and limits regarding revenue repayment.

   o Bonds of healthcare institutions which are subject to the strict rules and
     limits regarding reimbursement payments of California's Medi-Cal program
     for health care services to welfare recipients and bonds secured by liens
     on real property are two of the types of bonds that could be affected by
     these provisions.

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:

   o the high combined state and local tax burden;

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

   o sensitivity to the financial services industry; and

   o 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
about $2 billion are projected for the 2001 and 2002 fiscal years. New York City
faces fiscal pressures from:

   o aging public facilities that need repair or replacement;

   o welfare and medical costs;

   o expiring labor contracts; and

   o a high and increasing debt burden.

                                       19
<PAGE>
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. $30.7 billion of combined City, MAC and PBC debt is
outstanding, and the City proposes $23 billion of financing over fiscal
1999-2003.

OHIO RISKS

Generally

Overall, Ohio's economy is more cyclical than non-industrial states and the
nation as a whole:

   o manufacturing (including auto-related manufacturing) is an important part
     of Ohio's economy.

   o agriculture and related industries are also very important.

   o recent employment growth has been in non-manufacturing areas.

State Government

The Ohio general revenue fund for the current two-year period calls for
expenditures of over $36 billion:

   o because general fund receipts and payments do not match exactly, temporary
     cash-flow deficiencies occur throughout the year. Ohio law permits the
      state government to manage this problem by permitting the adjustment of
     payment schedules and the use of the total operating fund.

   o Ohio's general obligation bonds are currently rated Aa1 by Moody's; AA+ by
      Standard & Poor's (except for the State's highway bonds which Standard &
     Poor's rates AAA). Fitch rates Ohio's general obligation bonds and its
     highway bonds AA+. Other bonds issued by other State agencies may have
     lower ratings. Any of these ratings may be changed.

   o Ohio voters have authorized the State to incur debt to which taxes or
     excises are pledged for payment.

Education Financing

In 1997, the Ohio Supreme Court found major aspects of the State's school
funding system to be unconstitutional. The Court ruled that, although property
taxes can play a role in school financing, they can no longer be the primary
means of school financing. The Court stayed its ruling to allow the State to
devise a system that complied with the State's constitution. During that stay,
repayment provisions of certain bonds issued for school funding will remain
valid.

PENNSYLVANIA RISKS

Generally

Pennsylvania and many of its municipalities (including Philadelphia) have
undergone an economic decline:

   o coal, steel, railroads and other heavy industry historically associated
     with the Commonwealth has given way to increased competition from foreign
      producers.

   o agriculture and related industries are still an important part of the
      Commonwealth's economy.

   o recently, however, service sector industries (trade, medical and health
      services, education and financial services) have provided new sources of
     growth.

State and Local Governments

Historically, both the Commonwealth and the City of Philadelphia have
experienced serious revenue shortfalls. At the same time, rising demands for
state and local programs and

                                       20
<PAGE>
services (particularly medical assistance and cash assistance programs) have
lead to increased spending.

   o in recent years, both the Commonwealth and the City of Philadelphia have
     tried to balance their budgets with a mix of tax increases and spending
     cuts.

   o Philadelphia has considered significant service cuts and privatization of
     certain services which it has provided to date.

   o in 1991, the Commonwealth created the Pennsylvania Inter-Governmental
      Cooperation Authority ('PICA') which it authorized to issue debt to cover
      Philadelphia's budget shortfalls, eliminate the City's projected deficits
     and fund its capital spending. PICA issued approximately $1.76 billion of
     Special Revenue Bonds on Philadelphia's behalf. Its power to issue bonds on
     Philadelphia's behalf expired at the end of 1996; as of June 30, 1998,
     approximately $1.1 billion in PICA Special Revenue Bonds were outstanding.

   o Pennsylvania's general obligation bonds are currently rated Aa3 by Moody's
     and AA by Standard & Poor's. Philadelphia's general obligation bonds are
     rated Aaa by Moody's and BBB by Standard & Poor's. There can be no
     assurance that these ratings will not be lowered.

BOND QUALITY RISK

A reduction in a bond's rating may decrease its value and, indirectly, the value
of your investment in the Fund.

INSURANCE RELATED RISK

Some bonds are backed by insurance companies (as shown under Portfolios).
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

                                       21
<PAGE>
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 the 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 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

                                       22
<PAGE>
      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 1.90%. 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.

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.

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.

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

                                       23
<PAGE>
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. Legal,
typesetting, electronic filing and regulatory filing fees and expenses
associated with updating the Portfolio's registration statement yearly are also
now chargeable to the Portfolio. 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.

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

Any quarterly deferred sales fees you owe are paid with interest and principal
from certain bonds. If these amounts are not enough, the rest will be paid out
of distributitons to you from the Fund's Capital and Income Accounts.

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 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.

                                       24
<PAGE>
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.
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.

                                       25
<PAGE>
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

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

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. The Year 2000 Problem may adversely affect the issuers of the securities
contained in the Portfolio, but we cannot predict whether any impact will be
material to the Portfolio 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, 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,

                                       27

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 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.

CALIFORNIA TAXES

In the opinion of O'Melveny & Myers LLP, Los Angeles, California, special
counsel on California tax matters:

Under the income tax laws of the State of California, the Trust will not be
taxed as a corporation and you will be considered to own directly your share of
each bond of the Trust. If you are a California taxpayer, your share of the
income from the bonds of the Trust will not be tax-exempt in California except
for California personal income tax purposes and only to the extent that the
income is earned on bonds that are exempt for such purposes. If you are a
California taxpayer and all or part of your share of a bond is disposed of (for
example, when a bond is sold, exchanged or redeemed at maturity or you sell or
exchange your units), you will recognize gain or loss for California tax
purposes. Depending on where you live, your income from the Trust may be subject
to state and local taxation. You should consult your tax advisor in this regard.

OHIO TAXES

In the opinion of Vorys, Sater, Seymour and Pease LLP, Columbus, Ohio, special
counsel on Ohio tax matters:

Under the laws of the State of Ohio, the Ohio Trust will not be subject to the
Ohio corporation franchise tax or the Ohio tax on dealers in intangibles. If you
are an Ohio taxpayer, your interest income from the Ohio Trust will be exempt
from Ohio personal income taxes and Ohio corporation franchise taxes to the
extent it relates to bonds held by the Ohio Trust that are exempt from taxation
under Ohio law. However, any gains and losses which must be recognized for
federal income tax purposes (whether upon the sale of your units in the Ohio
Trust or upon the sale of bonds by the Ohio Trust) also must be recognized for
Ohio personal income and corporation franchise tax purposes, except to the
extent the gains and losses are attributable to the sale of bonds by the Ohio
Trust that are exempt from such taxation under Ohio law. Your interest income
and your gains and losses generally are not subject to municipal income taxation
in Ohio. You should consult your tax adviser concerning the application of Ohio
taxes to you in connection with your investment in the Ohio Trust.

PENNSYLVANIA TAXES

In the opinion of Drinker Biddle & Reath LLP, Philadelphia, Pennsylvania,
special counsel on Pennsylvania tax matters:

The Pennsylvania Trust will not be taxed as a corporation under the current
income tax laws of Pennsylvania. Your income from the Trust may be subject to
taxation depending on where you live. If you are a Pennsylvania taxpayer your
interest income from the Trust will be tax-exempt to the extent that income is
earned on bonds that are tax-exempt for Pennsylvania purposes. However, gains on
the sale of bonds by the Trust or on the sale of your units will be subject to
Pennsylvania income tax. If you are a Philadelphia resident you may be subject
to the Philadelphia school district tax on any gains realized from the sale of
bonds by the Trust or the sale of units by you to the extent either the bonds or
units have been held for six months or less. You should consult your tax adviser
as to the consequences to you with respect to any investment you make in the
Trust.

information about the structure and operation of the Fund. The supplemental
information is also available from the SEC.

          OHIO INSURED AND PENNSYLVANIA INSURED TRUSTS),
          DEFINED ASSET FUNDS

          REPORT OF INDEPENDENT ACCOUNTANTS

          The Sponsors, Trustee and Holders
          of Municipal Investment Trust Fund,
          Multistate Series - 307 (California Insured, New York,
          Ohio Insured and Pennsylvania Insured Trusts),
          Defined Asset Funds:

          We have audited the accompanying statements of condition of
          Municipal Investment Trust Fund, Multistate Series - 307
          (California Insured, New York, Ohio Insured and Pennsylvania
          Insured Trusts), including the portfolios, as of February 28,
          1999 and the related statements of operations and of changes
          in net assets for the year ended February 28, 1999 and
          the period March 24, 1997 to February 28, 1998. These financial
          statements are the responsibility of the Trustee. Our
          responsibility is to express an opinion on these financial
          statements based on our audits.

          We conducted our audits in accordance with generally
          accepted auditing standards. Those standards require that
          we plan and perform the audit to obtain reasonable
          assurance about whether the financial statements are free
          of material misstatement. An audit includes examining, on a
          test basis, evidence supporting the amounts and disclosures
          in the financial statements. Securities owned at February
          28, 1999, as shown in such portfolios, were confirmed to us
          by The Chase Manhattan Bank, the Trustee. An audit also
          includes assessing the accounting principles used and
          significant estimates made by the Trustee, as well as
          evaluating the overall financial statement presentation. We
          believe that our audits provide a reasonable basis for our
          opinion.

          In our opinion, the financial statements referred to
          above present fairly, in all material respects, the
          financial position of Municipal Investment Trust Fund,
          Multistate Series - 307 (California Insured, New York, Ohio
          Insured and Pennsylvania Insured Trusts), at February 28,
          1999 and the results of their operations and changes in their
          net assets for the above-stated periods in conformity with
          generally accepted accounting principles.

MUNICIPAL INVESTMENT TRUST FUND,
MULTISTATE SERIES - 307 (CALIFORNIA INSURED, NEW YORK,
OHIO INSURED AND PENNSYLVANIA INSURED TRUSTS),
DEFINED ASSET FUNDS

NOTES TO PORTFOLIOS
As of February 28, 1999

(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) See Notes to Financial Statements.

(3) Optional redemption provisions, which may be exercised in whole 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.

(4) All securities are insured, either on an individual basis or by portfolio
insurance, by a municipal bond insurance company which has been assigned
"AAA" claims paying ability by Standard & Poor's. Accordingly, Standard &
Poor's has assigned a "AAA" rating to the securities. Securities covered by
portfolio insurance are rated "AAA" only as long as they remain in the Trust.

(5) Insured by the indicated municipal bond insurance company.

(6) These bonds have been segregated to fund the deferred sales charges.

(7) Bonds with an aggregate face amount of $750,000 of the California Insured
Trust, $625,000 of the Ohio Insured Trust and $1,575,000 of the Pennsylvania
Insured Trust have been pre-refunded and are expected to be called for
redemption on the optional redemption provision dates shown.
