            THE FIRST TRUST OF INSURED MUNICIPAL BONDS, SERIES 220
                                 9,708 UNITS

PROSPECTUS
Part One
Dated July 25, 1997

Note: Part One of this Prospectus may not be distributed unless accompanied by
      Part Two and Part Three.

In the opinion of Counsel, interest income to the Trust and to Unit holders,
with certain exceptions, is exempt under existing law from all Federal income
taxes, but may be subject to state and local taxes.  Capital gains, if any,
are subject to tax accompanied by Part Two and Part Three.

The Trust

The First Trust of Insured Municipal Bonds, Series 220 (the "Trust") is an
insured and fixed portfolio of interest-bearing obligations issued by or on
behalf of municipalities and other governmental authorities, the interest on
which is, in the opinion of recognized bond counsel to the issuing
governmental authorities, exempt from all Federal income taxes under existing
law.  At June 16, 1997, each Unit represented a 1/9,708 undivided interest in
the principal and net income of the Trust (see "The Fund" in Part Two).

The Units being offered by this Prospectus are issued and outstanding Units
which have been purchased by the Sponsor in the secondary market or from the
Trustee after having been tendered for redemption.  The profit or loss
resulting from the sale of Units will accrue to the Sponsor.  No proceeds from
the sale of Units will be received by the Trust.

Public Offering Price

The Public Offering Price of the Units is equal to the aggregate value of the
Bonds in the Portfolio of the Trust divided by the number of Units
outstanding, plus a sales charge of 5.6% of the Public Offering Price (5.932%
of the amount invested).  At June 16, 1997, the Public Offering Price per Unit
was $1,035.06 plus net interest accrued to date of settlement (three business
days after such date) of $9.66 and $9.66 for the monthly and semi-annual
distribution plans, respectively (see "Market for Units" in Part Two).

       Please retain all parts of this Prospectus for future reference.

Estimated Current Return and Estimated Long-Term Return

Estimated Current Return to Unit holders under the semi-annual distribution
plan was 5.33% per annum on June 16, 1997, and 5.27% under the monthly
distribution plan.  Estimated Long-Term Return to Unit holders under the semi-
annual distribution plan was 4.82% per annum on June 16, 1997, and 4.75% under
the monthly distribution plan.  Estimated Current Return is calculated by
dividing the Estimated Net Annual Interest Income per Unit by the Public
Offering Price.  Estimated Long-Term Return is calculated using a formula
which (1) takes into consideration and determines and factors in the relative
weightings of the market values, yields (which take into account the
amortization of premiums and the accretion of discounts) and estimated
retirements of all of the Bonds in the Trust and (2) takes into account a
compounding factor and the expenses and sales charge associated with each Unit
of the Trust.  Since the market values and estimated retirements of the Bonds
and the expenses of the Trust will change, there is no assurance that the
present Estimated Current Return and Estimated Long-Term Return indicated
above will be realized in the future.  Estimated Current Return and Estimated
Long-Term Return are expected to differ because the calculation of the
Estimated Long-Term Return reflects the estimated date and amount of principal
returned while the Estimated Current Return calculations include only Net
Annual Interest Income and Public Offering Price.  The above figures are based
on estimated per Unit cash flows.  Estimated cash flows will vary with changes
in fees and expenses, with changes in current interest rates, and with the
principal prepayment, redemption, maturity, call, exchange or sale of the
underlying Bonds.  See "What are Estimated Current Return and Estimated Long-
Term Return?" in Part Two.

                        REPORT OF INDEPENDENT AUDITORS


The Unit Holders of The First Trust Combined
Series 186, The First Trust of Insured Municipal
Bonds, Series 220

We have audited the accompanying statement of assets and liabilities,
including the portfolio, of The First Trust Combined Series 186, The First
Trust of Insured Municipal Bonds, Series 220 as of March 31, 1997, and the
related statements of operations and changes in net assets for each of the
three years in the period then ended.  These financial statements are the
responsibility of the Trust's Sponsor.  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.  Our
procedures included confirmation of securities owned as of March 31, 1997, by
correspondence with the Trustee.  An audit also includes assessing the
accounting principles used and significant estimates made by the Sponsor, 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 The First Trust Combined
Series 186, The First Trust of Insured Municipal Bonds, Series 220 at
March 31, 1997, and the results of its operations and changes in its net
assets for each of the three years in the period then ended in conformity with
generally accepted accounting principles.

                              NOTES TO PORTFOLIO

                                March 31, 1997


(a)   Shown under this heading are the year in which each issue of Bonds is
      initially redeemable and the redemption price in that year.  Unless
      otherwise indicated, each issue continues to be redeemable at declining
      prices thereafter (but not below par value).  "S.F." indicates a sinking
      fund is established with respect to an issue of bonds.  In addition,
      certain bonds are sometimes redeemable in whole or in part other than by
      operation of the stated redemption or sinking fund provisions under
      specified unusual or extraordinary circumstances.  None of the Bonds in
      the Trust are subject to call within five years.

(b)   The ratings shown are those effective at March 31, 1997.

(c)   Insurance has been obtained by the Bond issuer.

(d)   These Bonds have no stated interest rate ("zero coupon bonds") and,
      accordingly, will have no periodic interest payments to the Trust.  Upon
      maturity, the holders of these Bonds are entitled to receive 100% of the
      stated principal amount.  The Bonds were issued at an original issue
      discount on the following dates and at the following percentages of
      their original principal amount:

         <S>                                      <C>           <C>

         Romulus Community Schools                  5/4/93       18.591
</TABLE>

(e)   The Trust consists of nine obligations of issues located in seven
      states.  Three bond issues aggregating approximately 32% of the
      aggregate principal amount of the Bonds in the Trust are obligations of
      issuers located in Illinois.  One of the Bonds in the Trust,
      representing approximately 3% of the aggregate principal amount of the
      Bonds in the Trust, is a general obligation of a governmental entity.
      The remaining issues are revenue bonds payable from the income of a
      specific project or authority and are divided by purpose of issue as
      follows:  Health Care, 3; Electric, 1; Transportation, 1; University and
      School, 2; and Miscellaneous, 1.  Approximately 31% and 28% of the
      aggregate principal amounts of the Bonds in the Trust consist of
      university and school revenue bonds and health care revenue bonds,
      respectively.  Each of six Bond issues represents 10% or more of the
      aggregate principal amount of the Bonds in the Trust or a total of
      approximately 83%.  The two largest such issues represent approximately
      16% each.

                        NOTES TO FINANCIAL STATEMENTS


1.  Significant accounting policies

Security valuation -

Bonds are stated at values as determined by Securities Evaluation Service,
Inc. (the Evaluator), certain shareholders of which are officers of the
Sponsor.  The bond values are based on (1) current bid prices for the bonds
obtained from dealers or brokers who customarily deal in bonds comparable to
those held by the Trust, (2) current bid prices for comparable bonds, (3)
appraisal or (4) any combination of the above (see Note 3).

Security cost -

The Trust's cost of its portfolio is based on the offering prices of the bonds
on the Date of Deposit, April 29, 1993.  The premium or discount (including
original issue discount) existing at the Date of Deposit is not being
amortized.  Realized gain (loss) from bond transactions is reported on an
identified cost basis.  Sales and redemptions of bonds are recorded on the
trade date.

Federal income taxes -

The Trust is not taxable for Federal income tax purposes.  Each unit holder is
considered to be the owner of a pro rata portion of the Trust and,
accordingly, no provision has been made for Federal income taxes.

Expenses of the Trust -

The Trust pays a fee for Trustee services which is based on $1.05 and $.55 per
$1,000 principal amount of Bonds for those portions of the Trust under the
monthly and semi-annual distribution plans, respectively.  Prior to September
1, 1995, the Trustee was United States Trust Company of New York; effective
September 1, 1995, The Chase Manhattan Bank succeeded United States Trust
Company of New York as Trustee.  Additionally, a fee of $2,913 annually is
payable to the Evaluator and the Trust pays all related expenses of the
Trustee, recurring financial reporting costs and an annual supervisory fee
payable to an affiliate of the Sponsor.

2.  Unrealized depreciation and depreciation

An analysis of net unrealized depreciation at March 31, 1997 follows:

</TABLE>


<PAGE>
3.  Insurance

The issuers of all bond issues in the Trust have acquired insurance coverage
which provides for the payment, when due, of all principal and interest on
those bonds (see Note (c) to Portfolio).  Such insurance coverage acquired by
an issuer of bonds continues in force so long as the bonds are outstanding and
the insurer remains in business.

4.  Other information

Cost to investors -

The cost to initial investors of units of the Trust was based on the aggregate
offering price of the bonds on the date of an investor's purchase, plus a
sales charge of 4.9% of the public offering price which is equivalent to
approximately 5.152% of the net amount invested.

Distributions of net interest income -

Distributions of net interest income to unit holders are made monthly or semi-
annually.  Such income distributions per unit, on an accrual basis, were as
follows:

PROSPECTUS
Part One
Dated July 25, 1997

Note: Part One of this Prospectus may not be distributed unless accompanied by
      Part Two and Part Three.

In the opinion of Counsel, interest income to the Trust and to Unit holders,
with certain exceptions, is exempt under existing law from all Federal income
taxes.  In addition, the interest income is, in the opinion of Special
Counsel, exempt to the extent indicated from California State and local income
taxes.  Capital gains, if any, are subject to tax.

The Trust

The First Trust of Insured Municipal Bonds - Multi-State California Trust,
Series 4 (the "Trust") is an insured and fixed portfolio of interest-bearing
obligations issued by or on behalf of municipalities and other governmental
authorities within the State of California, counties, municipalities,
authorities and political subdivisions thereof, the interest on which is, in
the opinion of recognized bond counsel to the issuing governmental
authorities, exempt from all Federal income taxes and from California State
and local income taxes under existing law.  At June 16, 1997, each Unit
represented a 1/2,525 undivided interest in the principal and net income of
the Trust (see "The Fund" in Part Two).

The Units being offered by this Prospectus are issued and outstanding Units
which have been purchased by the Sponsor in the secondary market or from the
Trustee after having been tendered for redemption.  The profit or loss
resulting from the sale of Units will accrue to the Sponsor.  No proceeds from
the sale of Units will be received by the Trust.

Public Offering Price

The Public Offering Price of the Units is equal to the aggregate value of the
Bonds in the Portfolio of the Trust divided by the number of Units
outstanding, plus a sales charge of 5.8% of the Public Offering Price (6.157%
of the amount invested).  At June 16, 1997, the Public Offering Price per Unit
was $1,027.06 plus net interest accrued to date of settlement (three business
days after such date) of $8.33 and $8.33 for the monthly and semi-annual
distribution plans, respectively (see "Market for Units" in Part Two).

       Please retain all parts of this Prospectus for future reference.

Estimated Current Return and Estimated Long-Term Return

Estimated Current Return to Unit holders under the semi-annual distribution
plan was 5.19% per annum on June 16, 1997, and 5.12% under the monthly
distribution plan.  Estimated Long-Term Return to Unit holders under the semi-
annual distribution plan was 4.83% per annum on June 16, 1997, and 4.76% under
the monthly distribution plan.  Estimated Current Return is calculated by
dividing the Estimated Net Annual Interest Income per Unit by the Public
Offering Price.  Estimated Long-Term Return is calculated using a formula
which (1) takes into consideration and determines and factors in the relative
weightings of the market values, yields (which take into account the
amortization of premiums and the accretion of discounts) and estimated
retirements of all of the Bonds in the Trust and (2) takes into account a
compounding factor and the expenses and sales charge associated with each Unit
of the Trust.  Since the market values and estimated retirements of the Bonds
and the expenses of the Trust will change, there is no assurance that the
present Estimated Current Return and Estimated Long-Term Return indicated
above will be realized in the future.  Estimated Current Return and Estimated
Long-Term Return are expected to differ because the calculation of the
Estimated Long-Term Return reflects the estimated date and amount of principal
returned while the Estimated Current Return calculations include only Net
Annual Interest Income and Public Offering Price.  The above figures are based
on estimated per Unit cash flows.  Estimated cash flows will vary with changes
in fees and expenses, with changes in current interest rates, and with the
principal prepayment, redemption, maturity, call, exchange or sale of the
underlying Bonds.  See "What are Estimated Current Return and Estimated Long-
Term Return?" in Part Two.

                        REPORT OF INDEPENDENT AUDITORS


The Unit Holders of The First Trust Combined
Series 186, The First Trust of Insured Municipal
Bonds  - Multi-State, California Trust, Series 4

We have audited the accompanying statement of assets and liabilities,
including the portfolio, of The First Trust Combined Series 186, The First
Trust of Insured Municipal Bonds - Multi-State, California Trust, Series 4 as
of March 31, 1997, and the related statements of operations and changes in net
assets for each of the three years in the period then ended.  These financial
statements are the responsibility of the Trust's Sponsor.  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.  Our
procedures included confirmation of securities owned as of March 31, 1997, by
correspondence with the Trustee.  An audit also includes assessing the
accounting principles used and significant estimates made by the Sponsor, 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 The First Trust Combined
Series 186, The First Trust of Insured Municipal Bonds - Multi-State,
California Trust, Series 4 at March 31, 1997, and the results of its
operations and changes in its net assets for each of the three years in the
period then ended in conformity with generally accepted accounting principles.

                              NOTES TO PORTFOLIO

                                March 31, 1997

(a)   Shown under this heading are the year in which each issue of Bonds is
      initially redeemable and the redemption price in that year.  Unless
      otherwise indicated, each issue continues to be redeemable at declining
      prices thereafter (but not below par value).  "S.F." indicates a sinking
      fund is established with respect to an issue of bonds.  In addition,
      certain bonds are sometimes redeemable in whole or in part other than by
      operation of the stated redemption or sinking fund provisions under
      specified unusual or extraordinary circumstances.  None of the Bonds in
      the trust are subject to call within five years.

(b)   The ratings shown are those effective at March 31, 1997.

(c)   Insurance has been obtained by the Bond issuer.

(d)   These Bonds have no stated interest rate ("zero coupon bonds") and,
      accordingly, will have no periodic interest payments to the Trust.  Upon
      maturity, the holders of these Bonds are entitled to receive 100% of the
      stated principal amount.  The Bonds were issued at an original issue
      discount on October 25, 1984 at a price of 11.625% of their original
      principal amount.

(e)   These Bonds were issued at an original issue discount on the following
      dates and at the following percentages of their original principal
      amount:

</TABLE>

(f)   This issue of Bonds is secured by, and payable from, escrowed U.S.
      Government securities.

(g)   The Trust consists of seven obligations of issues located in California.
      One of the Bonds in the Trust, representing approximately 18% of the
      aggregate principal amount of the Bonds in the Trust, is a general
      obligation of a governmental entity.  The remaining issues are revenue
      bonds payable from the income of a specific project or authority and are
      divided by purpose of issue as follows:  Water & Sewer, 2; Electric, 2;
      University and School, 1; and Single Family Housing, 1.  Approximately
      5%, 20%, 29% and 28% of the aggregate principal amount of the Bonds
      consist of single family residential mortgage revenue bonds, university
      and school revenue bonds, electric revenue bonds and water and sewer
      revenue bonds, respectively.  Each of six Bond issues represents 10% or
      more of the aggregate principal amount of the Bonds in the Trust or a
      total of approximately 95%.  The largest such issue represents
      approximately 20%.

                          CALIFORNIA TRUST, SERIES 4

                        NOTES TO FINANCIAL STATEMENTS

1.  Significant accounting policies

Security valuation  -

Bonds are stated at values as determined by Securities Evaluation Service,
Inc. (the Evaluator), certain shareholders of which are officers of the
Sponsor.  The bond values are based on (1) current bid prices for the bonds
obtained from dealers or brokers who customarily deal in bonds comparable to
those held by the Trust, (2) current bid prices for comparable bonds, (3)
appraisal or (4) any combination of the above.

Security cost  -

The Trust's cost of its portfolio is based on the offering prices of the bonds
on the Date of Deposit, April 29, 1993.  The premium or discount (including
original issue discount) existing at the Date of Deposit is not being
amortized.  Realized gain (loss) from bond transactions is reported on an
identified cost basis.  Sales and redemptions of bonds are recorded on the
trade date.

Federal income taxes  -

The Trust is not taxable for Federal income tax purposes.  Each unit holder is
considered to be the owner of a pro rata portion of the Trust and,
accordingly, no provision has been made for Federal income taxes.

Expenses of the Trust  -

The Trust pays a fee for Trustee services which is based on $1.05 and $.55 per
$1,000 principal amount of Bonds for those portions of the Trust under the
monthly and semi-annual distribution plans, respectively.  Prior to September
1, 1995, the Trustee was United States Trust Company of New York; effective
September 1, 1995, The Chase Manhattan Bank succeeded United States Trust
Company of New York as Trustee.  Additionally, a fee of $882 annually is
payable to the Evaluator and the Trust pays all related expenses of the
Trustee, recurring financial reporting costs and an annual supervisory fee
payable to an affiliate of the Sponsor.

2.  Unrealized appreciation and depreciation

An analysis of net unrealized depreciation at March 31, 1997 follows:

                                                                   ========

</TABLE>


<PAGE>
3.  Insurance

The issuers of all of the bond issues in the Trust have acquired insurance
coverage which provides for the scheduled payments, when due, of all principal
and interest on those bonds (see Note (c) to portfolio).  Such insurance
coverage acquired by an issuer of bonds continues in force so long as the
bonds are outstanding and the insurer remains in business.

4.  Other information

Cost to investors  -

The cost to initial investors of units of the Trust was based on the aggregate
offering price of the bonds on the date of an investor's purchase, plus a
sales charge of 4.9% of the public offering price which is equivalent to
approximately 5.152% of the net amount invested.

Distributions to unit holders  -

Distributions of net interest income to unit holders are made monthly or semi-
annually.  Such income distributions per unit, on an accrual basis, were as
follows:

The Trust

The First Trust of Insured Municipal Bonds - Multi-State New York Trust,

Trustee after having been tendered for redemption.  The profit or loss
resulting from the sale of Units will accrue to the Sponsor.  No proceeds from
the sale of Units will be received by the Trust.

Public Offering Price

The Public Offering Price of the Units is equal to the aggregate value of the
Bonds in the Portfolio of the Trust divided by the number of Units
outstanding, plus a sales charge of 5.5% of the Public Offering Price (5.820%
of the amount invested).  At June 16, 1997, the Public Offering Price per Unit
was $1,022.31 plus net interest accrued to date of settlement (three business
days after such date) of $7.87 and $7.87 for the monthly and semi-annual
distribution plans, respectively (see "Market for Units" in Part Two).

Estimated Current Return and Estimated Long-Term Return

Estimated Current Return to Unit holders under the semi-annual distribution
plan was 5.15% per annum on June 16, 1997, and 5.10% under the monthly
distribution plan.  Estimated Long-Term Return to Unit holders under the semi-
annual distribution plan was 4.77% per annum on June 16, 1997, and 4.72% under
the monthly distribution plan.  Estimated Current Return is calculated by
dividing the Estimated Net Annual Interest Income per Unit by the Public
Offering Price.  Estimated Long-Term Return is calculated using a formula
which (1) takes into consideration and determines and factors in the relative
weightings of the market values, yields (which take into account the
amortization of premiums and the accretion of discounts) and estimated
retirements of all of the Bonds in the Trust and (2) takes into account a
compounding factor and the expenses and sales charge associated with each Unit
of the Trust.  Since the market values and estimated retirements of the Bonds
and the expenses of the Trust will change, there is no assurance that the
present Estimated Current Return and Estimated Long-Term Return indicated
above will be realized in the future.  Estimated Current Return and Estimated
Long-Term Return are expected to differ because the calculation of the
Estimated Long-Term Return reflects the estimated date and amount of principal
returned while the Estimated Current Return calculations include only Net
Annual Interest Income and Public Offering Price.  The above figures are based
on estimated per Unit cash flows.  Estimated cash flows will vary with changes
in fees and expenses, with changes in current interest rates, and with the
principal prepayment, redemption, maturity, call, exchange or sale of the
underlying Bonds.  See "What are Estimated Current Return and Estimated Long-
Term Return?" in Part Two.

                        REPORT OF INDEPENDENT AUDITORS


The Unit Holders of The First Trust Combined
Series 186, The First Trust of Insured Municipal
Bonds - Multi-State, New York Trust, Series 47

We have audited the accompanying statement of assets and liabilities,
including the portfolio, of The First Trust Combined Series 186, The First
Trust of Insured Municipal Bonds - Multi-State, New York Trust, Series 47 as
of March 31, 1997, and the related statements of operations and changes in net
assets for each of the three years in the period then ended.  These financial
statements are the responsibility of the Trust's Sponsor.  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.  Our
procedures included confirmation of securities owned as of March 31, 1997, by
correspondence with the Trustee.  An audit also includes assessing the
accounting principles used and significant estimates made by the Sponsor, 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 The First Trust Combined
Series 186, The First Trust of Insured Municipal Bonds - Multi-State, New York
Trust, Series 47 at March 31, 1997, and the results of its operations and
changes in its net assets for each of the three years in the period then ended
in conformity with generally accepted accounting principles.

                              NOTES TO PORTFOLIO

                                March 31, 1997


(a)   Shown under this heading are the year in which each issue of Bonds is
      initially redeemable and the redemption price in that year.  Unless
      otherwise indicated, each issue continues to be redeemable at declining
      prices thereafter (but not below par value).  "S.F." indicates a sinking
      fund is established with respect to an issue of bonds.  In addition,
      certain bonds are sometimes redeemable in whole or in part other than by
      operation of the stated redemption or sinking fund provisions under
      specified unusual or extraordinary circumstances.  Approximately 20% of
      the aggregate principal amount of the Bonds in the Trust is subject to
      call within five years.

(b)   The ratings shown are those effective at March 31, 1997.

(c)   Insurance has been obtained by the Bond issuer.

(d)   These Bonds have no stated interest rate ("zero coupon bonds") and,
      accordingly, will have no periodic interest payments to the Trust.  Upon
      maturity, the holders of these Bonds are entitled to receive 100% of the
      stated principal amount.  The Bonds were issued at an original issue
      discount on January 15, 1992 at a price of 15.221% of their original
      principal amount.

(e)   These Bonds were issued at an original issue discount on the following
      dates and at the following percentages of their original principal
      amount:

</TABLE>


(f)   This issue of Bonds is secured by, and payable from, escrowed U.S.
      Government securities.

(g)   The Trust consists of seven obligations of issuers located in New York.
      None of the Bonds in the Trust are general obligations of a governmental
      entity.  All issues are revenue bonds payable from the income of a
      specific project or authority and are divided by purpose of issue as
      follows:  Water & Sewer, 1; Transportation, 3; Health Care, 2; and
      Miscellaneous, 1.  Approximately 37% and 39% of the aggregate principal
      amount of the Bonds consist of transportation revenue bonds and health
      care revenue bonds, respectively.  Each of five Bond issues represents
      10% or more of the aggregate principal amount of the Bonds in the Trust
      or a total of approximately 89%.  The two largest such issues represent
      approximately 20% each.

           THE FIRST TRUST OF INSURED MUNICIPAL BONDS - MULTI-STATE
                          NEW YORK TRUST, SERIES 47

                        NOTES TO FINANCIAL STATEMENTS

1.  Significant accounting policies

Security valuation  -

Bonds are stated at values as determined by Securities Evaluation Service,
Inc. (the Evaluator), certain shareholders of which are officers of the
Sponsor.  The bond values are based on (1) current bid prices for the bonds
obtained from dealers or brokers who customarily deal in bonds comparable to
those held by the Trust, (2) current bid prices for comparable bonds, (3)
appraisal or (4) any combination of the above.

Security cost  -

The Trust's cost of its portfolio is based on the offering prices of the bonds
on the Date of Deposit, April 29, 1993.  The premium or discount (including
original issue discount) existing at the Date of Deposit is not being
amortized.  Realized gain (loss) from bond transactions is reported on an
identified cost basis.  Sales and redemptions of bonds are recorded on the
trade date.

Federal income taxes  -

The Trust is not taxable for Federal income tax purposes.  Each unit holder is
considered to be the owner of a pro rata portion of the Trust and,
accordingly, no provision has been made for Federal income taxes.

Expenses of the Trust  -

The Trust pays a fee for Trustee services which is based on $1.05 and $.55 per
$1,000 principal amount of Bonds for those portions of the Trust under the
monthly and semi-annual distribution plans, respectively.  Prior to September
1, 1995, the Trustee was United States Trust Company of New York; effective
September 1, 1995, The Chase Manhattan Bank succeeded United States Trust
Company of New York as Trustee.  Additionally, a fee of $884 annually is
payable to the Evaluator and the Trust pays all related expenses of the
Trustee, recurring financial reporting costs and an annual supervisory fee
payable to an affiliate of the Sponsor.

2.  Unrealized appreciation and depreciation

An analysis of net unrealized depreciation at March 31, 1997 follows:

</TABLE>


<PAGE>
3.  Insurance

The issuers of all of the bond issues in the Trust have acquired insurance
coverage which provides for the payment, when due, of all principal and
interest on those bonds (see Note (c) to Portfolio).  Such insurance coverage
continues in force so long as the bonds are outstanding and the insurer
remains in business.

4.  Other information

Cost to investors  -

The cost to initial investors of units of the Trust was based on the aggregate
offering price of the bonds on the date of an investor's purchase, plus a
sales charge of 4.9% of the public offering price which is equivalent to
approximately 5.152% of the net amount invested.

Distributions to unit holders  -

Distributions of net interest income to unit holders are made monthly or semi-
annually.  Such income distributions per unit, on an accrual basis, were as
follows:

This Prospectus does not constitute an offer to sell, or a solicitation of an
offer to buy, securities in any jurisdiction to any person to whom it is not
lawful to make such offer in such jurisdiction.

This Prospectus does not contain all the information set forth in the
registration statement and exhibits relating thereto, which the Trust has
filed with the Securities and Exchange Commission, Washington, D.C., under the
Securities Act of 1933 and the Investment Company Act of 1940, and to which
reference is hereby made.



          The First Trust(registered trademark) Combined Series

PROSPECTUS                         NOTE: THIS PART TWO PROSPECTUS MAY
Part Two                                   ONLY BE USED WITH PART ONE
Dated May 30, 1997                                     AND PART THREE

IN THE OPINION OF COUNSEL, INTEREST INCOME TO THE TRUSTS AND TO THE UNIT
HOLDERS, WITH CERTAIN EXCEPTIONS, IS EXEMPT UNDER EXISTING LAW FROM ALL
FEDERAL INCOME TAXES. IN ADDITION, THE INTEREST INCOME TO THE TRUSTS IS,
IN THE OPINION OF SPECIAL COUNSEL, EXEMPT TO THE EXTENT INDICATED FROM
STATE AND LOCAL TAXES WHEN HELD BY RESIDENTS OF THE STATE IN WHICH THE
ISSUERS OF THE BONDS IN SUCH TRUSTS ARE LOCATED. CAPITAL GAINS, IF ANY,
ARE SUBJECT TO TAX.

THE FIRST TRUST COMBINED SERIES (the "Fund") consists of underlying
separate unit investment trusts (the "Trusts"). The various trusts are
collectively referred to herein as the "Trusts" while all Trusts that
are not designated as "The First Trust Advantage" are sometimes
collectively referred to herein as the "Insured Trusts" and a Trust with
the name designation of "The First Trust of Insured Municipal Bonds,
Discount Trust" or "The First Trust Advantage: Discount Trust" is
sometimes referred to herein as a "Discount Trust." Each Trust consists
of a portfolio of interest-bearing obligations, issued by or on behalf
of states and territories of the United States, and political
subdivisions and authorities thereof, the interest on which is, in the
opinion of recognized bond counsel to the issuing governmental
authorities, exempt from all Federal income taxes under existing law
although interest on certain Bonds in certain Arkansas, Idaho, Kansas,
Maine, Mississippi and Nebraska Trusts will be a preference item for
purposes of the Alternative Minimum Tax. In addition, the interest
income of each Trust is, in the opinion of Special Counsel, exempt to
the extent indicated from state and local income taxes when held by
residents of the state in which the issuers of the Bonds in such Trust
are located. The securities in a Discount Trust are acquired at prices
which result in a Discount Trust portfolio, as a whole, being purchased
at a deep discount from the aggregate par value of such Securities
although a substantial portion of the Securities in a Discount Trust
portfolio may be acquired at a premium over the par value of such
Securities. All of the Bonds in an Intermediate Trust mature within 8 to
12 years of the Initial Date of Deposit. All of the Bonds in a Short
Intermediate Trust mature within 3 to 6 years of the Initial Date of
Deposit. All of the Bonds in a Long Intermediate Trust mature within 10
to 15 years of the Initial Date of Deposit. The portfolio for each
Trust, essential information based thereon and financial statements,
including a report of independent auditors relating to the series of the
Fund offered hereby, are contained in Part One to which reference should
be made for such information.

INSURANCE GUARANTEEING THE SCHEDULED PAYMENTS OF PRINCIPAL AND INTEREST
ON ALL BONDS IN THE PORTFOLIO OF EACH INSURED TRUST HAS BEEN OBTAINED
FROM FINANCIAL GUARANTY INSURANCE COMPANY AND/OR AMBAC INDEMNITY
CORPORATION BY THE INSURED TRUSTS OR WAS DIRECTLY OBTAINED BY THE BOND
ISSUER, THE UNDERWRITERS, THE SPONSOR OR OTHERS PRIOR TO THE INITIAL
DATE OF DEPOSIT FROM FINANCIAL GUARANTY INSURANCE COMPANY, AMBAC
INDEMNITY CORPORATION, OR OTHER INSURERS (THE "PREINSURED BONDS").
INSURANCE OBTAINED BY AN INSURED TRUST APPLIES ONLY WHILE BONDS ARE
RETAINED IN SUCH TRUST, WHILE INSURANCE ON PREINSURED BONDS IS EFFECTIVE
SO LONG AS SUCH BONDS ARE OUTSTANDING. PURSUANT TO AN IRREVOCABLE
COMMITMENT OF FINANCIAL GUARANTY INSURANCE COMPANY, AND/OR AMBAC
INDEMNITY CORPORATION IN THE EVENT OF A SALE OF A BOND INSURED UNDER AN
INSURANCE POLICY OBTAINED BY AN INSURED TRUST, THE TRUSTEE HAS THE RIGHT
TO OBTAIN PERMANENT INSURANCE FOR SUCH BOND UPON THE PAYMENT OF A SINGLE
PREDETERMINED INSURANCE PREMIUM FROM THE PROCEEDS OF THE SALE OF SUCH
BOND. THE INSURANCE, IN EITHER CASE, RELATES ONLY TO THE BONDS IN THE
INSURED TRUSTS AND NOT TO THE UNITS OFFERED HEREBY. AS A RESULT OF SUCH
INSURANCE, THE UNITS OF EACH INSURED TRUST HAVE RECEIVED A RATING OF
"AAA" BY STANDARD & POOR'S RATINGS GROUP, A DIVISION OF MCGRAW-HILL,
INC. ("STANDARD & POOR'S"). SEE "WHY AND HOW ARE THE INSURED TRUSTS
INSURED?" ON PAGE 12. NO REPRESENTATION IS MADE AS TO ANY INSURER'S
ABILITY TO MEET ITS COMMITMENTS.

ALL PARTS OF THE PROSPECTUS SHOULD BE RETAINED FOR FUTURE REFERENCE.

  All Parts of the Prospectus Should be Retained for Future Reference.

THESE SECURITIES HAVE NOT BEEN APPROVED OR DISAPPROVED BY THE SECURITIES
AND EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION NOR HAS THE
SECURITIES AND EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION
PASSED UPON THE ACCURACY OR ADEQUACY OF THIS PROSPECTUS. ANY
REPRESENTATION TO THE CONTRARY IS A CRIMINAL OFFENSE.

For convenience the Prospectus is divided into sections which give
general information about the Fund and specific information such as the
public offering price, distributions and tax status for each Trust.

The Objectives of the Fund are conservation of capital through
investment in portfolios of tax-exempt bonds and income exempt from
Federal and applicable state and local income taxes although interest on
certain Bonds in certain Arkansas, Idaho, Kansas, Maine, Mississippi and
Nebraska Trusts will be a preference item for purposes of the Federal
Alternative Minimum Tax. ACCORDINGLY, CERTAIN ARKANSAS, IDAHO, KANSAS,
MAINE, MISSISSIPPI AND NEBRASKA TRUSTS MAY BE APPROPRIATE ONLY FOR
INVESTORS WHO ARE NOT SUBJECT TO THE ALTERNATIVE MINIMUM TAX. CERTAIN
BONDS IN THE OKLAHOMA TRUSTS ARE SUBJECT TO OKLAHOMA STATE INCOME TAXES.
The payment of interest and the preservation of principal are, of
course, dependent upon the continuing ability of the issuers, obligors
and/or insurers to meet their respective obligations.

Distributions to Unit holders may be reinvested as described herein. See
"How Can Distributions to Unit Holders be Reinvested?"

The Sponsor, although not obligated to do so, intends to maintain a
market for the Units at prices based upon the aggregate bid price of the
Bonds in the portfolio of each Trust. In the absence of such a market, a
Unit holder will nonetheless be able to dispose of the Units through
redemption at prices based upon the bid prices of the underlying Bonds.
See "How May Units be Redeemed?" With respect to each Insured Trust,
neither the bid nor offering prices of the underlying Bonds or of the
Units, absent situations in which Bonds are in default in payment of
principal or interest or in significant risk of such default, include
value attributable to the portfolio insurance obtained by such Trust.
See "Why and How are the Insured Trusts Insured?"

                     THE FIRST TRUST COMBINED SERIES

What is The First Trust Combined Series? 

The First Trust Combined Series (the "Fund") is one of a series of
investment companies created by the Sponsor under the name of The First
Trust Combined Series, all of which are generally similar but each of
which is separate and is designated by a different series number. This
Series consists of underlying separate unit investment trusts (such
Trusts being collectively referred to herein as the "Fund"). Each Series
was created under the laws of the State of New York pursuant to a Trust
Agreement (the "Indenture"), dated the Initial Date of Deposit, with
Nike Securities L.P., as Sponsor, The Chase Manhattan Bank, as Trustee,
Securities Evaluation Service, Inc., as Evaluator and First Trust
Advisors L.P., as Portfolio Supervisor. Only Units of a National Trust
may be offered for sale to residents of the State of Illinois. Only
Units of an Indiana Trust and/or a National Trust may be offered for
sale to residents of the State of Indiana. Only Units of a Virginia
Trust and/or a National Trust may be offered for sale to residents of
the State of Virginia. Only Units of a Washington Trust and/or a
National Trust may be offered for sale to residents of Washington. On
the Initial Date of Deposit, the Sponsor deposited with the Trustee
interest-bearing obligations, including delivery statements relating to
contracts for the purchase of certain such obligations and irrevocable
letters of credit issued by a financial institution in the amounts
required for such purchases (the "Bonds"). The Trustee thereafter
credited the account of the Sponsor for Units of each Trust representing
the entire ownership of the Fund which Units are being offered hereby.

The objectives of the Fund are Federal tax-exempt income and state and
local tax-exempt income and conservation of capital through investment
in portfolios of interest-bearing obligations issued by or on behalf of
the state for which such Trust is named (collectively, the "State
Trusts"), and counties, municipalities, authorities and political
subdivisions thereof, the Commonwealth of Puerto Rico and other
territories or municipalities of the United States, or authorities or
political subdivisions thereof, the interest on which obligations is, in
the opinion of recognized bond counsel to the issuing governmental
authorities, exempt from all Federal income tax and, where applicable,
state and local taxes under existing law although interest on certain
Bonds in certain Arkansas, Idaho, Kansas, Maine, Mississippi and
Nebraska Trusts will be a preference item for purposes of the
Alternative Minimum Tax and certain Bonds in the Oklahoma Trusts are
subject to Oklahoma State Income Taxes. The current market value of
certain of the obligations in a Discount Trust were significantly below
face value when the obligations were acquired by such Trust. The prices
at which the obligations are acquired result in a Discount Trust's
portfolio, as a whole, being purchased at a deep discount from the
aggregate par value of such Securities although a substantial portion of
the Securities in a Discount Trust portfolio may be acquired at a
premium over the par value of such Securities. Insurance guaranteeing
the scheduled payment of all principal and interest on Bonds in the
Trusts with the name designation of "The First Trust of Insured
Municipal Bonds," "The First Trust of Insured Municipal Bonds-
Intermediate" or "The First Trust of Insured Municipal Bonds-Multi-
State" (the "Insured Trusts") has been obtained by such Trusts from
Financial Guaranty Insurance Company ("Financial Guaranty") and/or AMBAC
Indemnity Corporation ("AMBAC Indemnity") or was obtained directly by
the Bond issuer, the underwriters, the Sponsor or others prior to the
Initial Date of Deposit from Financial Guaranty, AMBAC Indemnity, or
other insurers (the "Preinsured Bonds"). NO PORTFOLIO INSURANCE POLICY
HAS BEEN OBTAINED BY THE TRUSTS WITH THE NAME DESIGNATION OF "THE FIRST
TRUST ADVANTAGE" (THE "ADVANTAGE TRUSTS"). The portfolio insurance
obtained by the Insured Trusts is effective only while the Bonds thus
insured are held in such Trusts, while insurance on Preinsured Bonds is
effective so long as such Bonds are outstanding. See "Why and How are
the Insured Trusts Insured?" THERE IS, OF COURSE, NO GUARANTEE THAT THE
FUND'S OBJECTIVES WILL BE ACHIEVED. AN INVESTMENT IN THE FUND SHOULD BE
MADE WITH AN UNDERSTANDING OF THE RISKS WHICH AN INVESTMENT IN FIXED
RATE LONG-TERM DEBT OBLIGATIONS MAY ENTAIL, INCLUDING THE RISK THAT THE
VALUE OF THE UNITS WILL DECLINE WITH INCREASES IN INTEREST RATES.

Neither the Public Offering Price of the Units of an Insured Trust nor
any evaluation of such Units for purposes of repurchases or redemptions
reflects any element of value for the insurance obtained by such Trust
unless Bonds are in default in payment of principal or interest or in
significant risk of such default. See "Public Offering-How is the Public
Offering Price Determined?" On the other hand, the value of insurance

Page 3

obtained by the Bond issuer, the Sponsor or others is reflected and
included in the market value of such Bonds. 

Insurance obtained by an Insured Trust or by the Bond issuer, the
Sponsor or others is not a substitute for the basic credit of an issuer,
but supplements the existing credit and provides additional security
therefor. If an issue is accepted for insurance, a noncancelable policy
for the scheduled payment of interest and principal on the Bonds is
issued by the insurer. A single premium is paid by the Bond issuer, the
underwriters, the Sponsor or others for Preinsured Bonds and a monthly
premium is paid by each Insured Trust for the insurance obtained by such
Trust except for Bonds in such Trust which are insured by the Bond
issuer, the underwriters, the Sponsor or others in which case no
premiums for insurance are paid by such Trust. Upon the sale of a Bond
insured under the insurance policy obtained by an Insured Trust, the
Trustee has the right to obtain permanent insurance from Financial
Guaranty and/or AMBAC Indemnity with respect to such Bond upon the
payment of a single predetermined insurance premium from the proceeds of
the sale of such Bond. Accordingly, any Bond in an Insured Trust of the
Fund is eligible to be sold on an insured basis. Standard & Poor's and
Moody's Investors Service, Inc. have rated the claims-paying ability of
Financial Guaranty and AMBAC Indemnity "AAA" and "Aaa," respectively.
See "Why and How are the Insured Trusts Insured?" 

In selecting Bonds, the following facts, among others, were considered:
(i) the Standard & Poor's rating or Fitch Investors Service, Inc.'s
rating of the Bonds was in no case less than "BBB" in the case of an
Insured Trust (or an Arkansas, Kansas or Maine Advantage Trust) and "A-"
in the case of other Advantage Trusts, or the Moody's Investors Service,
Inc. rating of the Bonds was in no case less than "Baa" in the case of
an Insured Trust (or an Arkansas, Kansas or Maine Advantage Trust) and
"A" in the case of other Advantage Trusts, including provisional or
conditional ratings, respectively, or, if not rated, the Bonds had, in
the opinion of the Sponsor, credit characteristics sufficiently similar
to the credit characteristics of interest-bearing tax-exempt obligations
that were so rated as to be acceptable for acquisition by the Fund (see
"Description of Bond Ratings"); (ii) the prices of the Bonds relative to
other bonds of comparable quality and maturity; (iii) with respect to
the Insured Trusts, the availability and cost of insurance of the
principal and interest on the Bonds and (iv) the diversification of
Bonds as to purpose of issue and location of issuer. Subsequent to the
Initial Date of Deposit, a Bond may cease to be rated or its rating may
be reduced below the minimum required as of the Initial Date of Deposit.
Neither event requires elimination of such Bond from the portfolio, but
may be considered in the Sponsor's determination as to whether or not to
direct the Trustee to dispose of the Bond. See "Rights of Unit Holders-
How May Bonds be Removed from the Fund?" The Portfolio appearing in Part
One contains Bond ratings, when available, for the Bonds listed at the
date shown.

Certain of the Bonds in the Trusts may have been acquired at a market
discount from par value at maturity. The coupon interest rates on the
discount bonds at the time they were purchased and deposited in the
Trust were lower than the current market interest rates for newly issued
bonds of comparable rating and type. The market discount of previously
issued bonds will increase when interest rates for newly issued
comparable bonds increase and decrease when such interest rates fall,
other things being equal. A discount bond held to maturity will have a
larger portion of its total return in the form of taxable income and
capital gain and less in the form of tax-exempt interest income than a
comparable bond newly issued at current market rates. See "What is the
Federal Tax Status of Unit Holders?" appearing in Part Three for each
Trust.

Certain of the Bonds in the Trusts may be original issue discount bonds.
Under current law, the original issue discount, which is the difference
between the stated redemption price at maturity and the issue price of
the Bonds, is deemed to accrue on a daily basis and the accrued portion
is treated as tax-exempt interest income for Federal income tax
purposes. On sale or redemption, any gain realized that is in excess of
the earned portion of original issue discount will be taxable as capital
gain unless the gain is attributable to market discount in which case
the accretion of market discount is taxable as ordinary income. See
"What is the Federal Tax Status of Unit Holders?" appearing in Part
Three for each Trust. The current value of an original discount bond
reflects the present value of its stated redemption price at maturity.
The market value tends to increase in greater increments as the Bonds
approach maturity.

Certain of the original issue discount bonds may be Zero Coupon Bonds
(including bonds known as multiplier bonds, money multiplier bonds,

Page 4

capital appreciation bonds, capital accumulator bonds, compound interest
bonds and money discount maturity payment bonds). Zero Coupon Bonds do
not provide for the payment of any current interest and generally
provide for payment at maturity at face value unless sooner sold or
redeemed. Zero Coupon bond features include (1) not paying interest on a
semi-annual basis and (2) providing for the reinvestment of the bond's
semi-annual earnings at the bond's stated yield to maturity. While Zero
Coupon Bonds are frequently marketed on the basis that their fixed rate
of return minimizes reinvestment risk, this benefit can be negated in
large part by weak call protection.

Certain of the Bonds in the Trusts may have been acquired at a market
premium from par value at maturity. The coupon interest rates on the
premium bonds at the time they were purchased and deposited in the
Trusts were higher than the current market interest rates for newly
issued bonds of comparable rating and type. The current returns of bonds
trading at a market premium are initially higher than the current
returns of comparable bonds of a similar type issued at currently
prevailing interest rates because premium bonds tend to decrease in
market value as they approach maturity when the face amount becomes
payable. Because part of the purchase price is thus returned not at
maturity but through current income payments, early redemption of a
premium bond at par or early prepayments of principal will result in a
reduction in yield. Redemptions are more likely to occur at times when
the Bonds have an offering side valuation which represents a premium
over par, or for original issue discount Bonds, a premium over the
accreted value. To the extent that the Bonds were deposited in the Fund
at a price higher than the price at which they are redeemed, this will
represent a loss of capital when compared to the original Public
Offering Price of the Units. Because premium bonds generally pay a
higher rate of interest than bonds priced at or below par, the effect of
the redemption of premium bonds would be to reduce Estimated Net Annual
Unit Income by a greater percentage than the par amount of such bonds
bears to the total par amount of Bonds in the Trust. Although the actual
impact of any such redemptions that may occur will depend upon the
specific Bonds that are redeemed, it can be anticipated that the
Estimated Net Annual Unit Income will be significantly reduced after the
dates on which such Bonds are eligible for redemption. The Trust may be
required to sell Zero Coupon Bonds prior to maturity (at their current
market price which is likely to be less than their par value) in order
to pay expenses of the Trust or in case the Trust is terminated. See
"Rights of Unit Holders-How May Bonds be Removed from the Fund?" and
"Other Information-How May the Indenture be Amended or Terminated?"

Certain of the Bonds in the Trusts may be general obligations of a
governmental entity that are backed by the taxing power of such entity.
All other Bonds in the Trusts are revenue bonds payable from the income
of a specific project or authority and are not supported by the issuer's
power to levy taxes. General obligation bonds are secured by the
issuer's pledge of its faith, credit and taxing power for the payment of
principal and interest. Revenue bonds, on the other hand, are payable
only from the revenues derived from a particular facility or class of
facilities or, in some cases, from the proceeds of a special excise tax
or other specific revenue source. There are, of course, variations in
the security of the different Bonds in the Fund, both within a
particular classification and between classifications, depending on
numerous factors. 

Certain of the Bonds in the Trusts may be healthcare revenue bonds.
Healthcare revenue bonds are obligations of issuers whose revenues are
primarily derived from services provided by hospitals or other
healthcare facilities, including nursing homes. A healthcare issuer's
ability to make debt service payments on these obligations is dependent
on various factors, including occupancy levels of the facility, demand,
government regulations, wages of employees, overhead expenses,
competition from other similar providers, malpractice insurance costs
and the degree of governmental competition from other similar providers,
malpractice insurance costs and the degree of governmental financial
assistance, including Medicare and Medicaid and other similar third-
party payer programs.

Certain of the Bonds in the Trusts may be housing revenue bonds. Housing
revenue bonds are obligations of issuers whose revenues are primarily
derived from mortgage loans on single family residences or housing
projects for low to moderate income families. Housing revenue bonds are
generally payable at any time and therefore their average life will
ordinarily be less than their stated maturities. The ability of such
issuers to make debt service payments on these obligations is dependent
on various factors, including occupancy levels, rental income, mortgage
default rates, taxes, operating expenses, governmental regulations and
the appropriation of subsidies.

Page 5


Certain of the Bonds in the Trusts may be obligations of issuers whose
revenues are derived from the sale of water and/or sewerage services.
Water and sewerage bonds are generally payable from user fees. Problems
faced by such issuers include the ability to obtain timely and adequate
rate increases, population decline resulting in decreased user fees, the
difficulty of financing large construction programs, the limitations on
operations and increased costs and delays attributable to environmental
considerations, the increasing difficulty of obtaining or discovering
new supplies of fresh water, the effect of conservation programs and the
impact of "no-growth" zoning ordinances.

Certain of the Bonds in the Trusts may be obligations of issuers whose
revenues are primarily derived from the sale of electric energy.
Utilities are generally subject to extensive regulation by state utility
commissions which, among other things, establish the rates which may be
charged and the appropriate rate of return. The problems faced by such
issuers include the difficulty in obtaining approval for timely and
adequate rate increases from the governing public utility commission,
the difficulty in financing large construction programs, increased
federal, state and municipal government regulations, the limitations on
operations and increased costs and delays attributable to environmental
considerations, increased competition, recent reductions in estimates of
future demand for electricity in certain areas of the country, the
difficulty of the capital market in absorbing utility debt, the
difficulty in obtaining fuel at reasonable prices and the effect of
energy conservation. 

Certain of the Bonds in the Trusts may be lease obligations issued
primarily by governmental authorities that have no taxing power or other
means of directly raising revenues. Rather, the governmental authorities
are financing vehicles created solely for the construction of buildings
(i.e., schools, administrative offices, convention centers and prisons)
or the purchase of equipment (i.e., police cars and computer systems)
that will be used by a state or local government (the "lessee"). These
obligations are subject to the ability and willingness of the lessee
government to meet its lease rental payments which include debt service
on the obligations. Lease obligations are subject, in almost all cases,
to annual appropriation risk, i.e., the lessee government is not legally
obligated to budget and appropriate for the rental payments beyond the
current fiscal year, or construction and abatement risk-rental
obligations cease in the event that delays in building, damage,
destruction or condemnation of the project prevents its use by the
lessee. 

Certain of the Bonds in the Trusts may be industrial revenue bonds
("IRBs"), tax-exempt securities issued by states, municipalities, public
authorities or similar entities to finance the cost of acquiring,
constructing or improving various industrial projects. Debt service
payments on IRBs are dependent on various factors, including the
creditworthiness of the corporate operator of the project and, if
applicable, corporate guarantor, revenues generated from the project
and, if applicable, corporate guarantor, revenues generated from the
project and regulatory and environmental restrictions.

Certain of the Bonds in the Trusts may be obligations which are payable
from and secured by revenues derived from the ownership and operation of
facilities such as airports, bridges, turnpikes, port authorities,
convention centers and arenas. The ability of issuers to make debt
service payments on airport obligations is dependent on the capability
of airlines to meet their obligations under use agreements. Due to
increased competition, deregulation, increased fuel costs and other
factors, many airlines may have difficulty meeting their obligations
under these use agreements. Similarly, payment on Bonds related to other
facilities is dependent on revenues from the projects, such as user fees
from ports, tolls on turnpikes and bridges and rents from buildings.
Therefore, payment may be adversely affected by reduction in revenues
due to such factors as increased cost of maintenance, decreased use of a
facility, lower cost of alternative modes of transportation, scarcity of
fuel and reduction or loss of rents.

Certain of the Bonds in the Trusts may be obligations of issuers which
govern the operation of schools, colleges and universities and whose
revenues are derived mainly from ad valorem taxes. General problems
relating to college and university obligations would include the
prospect of a declining percentage of the population consisting of
"college" age individuals, possible inability to raise tuitions and fees
sufficiently to cover increased operating costs, the uncertainty of
continued receipt of Federal grants and state funding and new government
legislation or regulations which may adversely affect the revenues or
costs of such issuers.

Certain of the Bonds in the Trusts may be obligations which are payable
from and secured by revenues derived from the operation of resource
recovery facilities. Resource recovery facilities are designed to

Page 6

process solid waste, generate steam and convert steam to electricity.
Resource recovery bonds may be subject to extraordinary optional
redemption at par upon the occurrence of certain circumstances,
including but not limited to: destruction or condemnation of a project;
contracts relating to a project becoming void, unenforceable or
impossible to perform; changes in the economic availability of raw
materials, operating supplies or facilities necessary for the operation
of a project or technological or other unavoidable changes adversely
affecting the operation of a project; administrative or judicial actions
which render contracts relating to the projects void, unenforceable or
impossible to perform; or impose unreasonable burdens or excessive
liabilities.

Certain Trusts may contain Bonds of issuers located in the Commonwealth
of Puerto Rico or issuers which will be affected by general economic
conditions of Puerto Rico. Puerto Rico's unemployment rate remains
significantly higher than the U.S. unemployment rate. Furthermore, the
economy is largely dependent for its development upon U.S. policies and
programs that are being reviewed and may be eliminated.

The Puerto Rican economy consists principally of manufacturing
(pharmaceuticals, scientific instruments, computers, microprocessors,
medical products, textiles and petrochemicals), agriculture (largely
sugar) and tourism. Most of the island's manufacturing output is shipped
to the mainland United States, which is also the chief source of semi-
finished manufactured articles on which further manufacturing operations
are performed in Puerto Rico. Since World War II the economic importance
of agriculture for Puerto Rico, particularly in the dominance of sugar
production, has declined. Nevertheless, the Commonwealth-controlled
sugar monopoly remains an important economic factor and is largely
dependent upon Federal maintenance of sugar prices, the discontinuation
of which could severely affect Puerto Rico sugar production. The level
of tourism is affected by various factors including the strength of the
U.S. dollar. During periods when the dollar is strong, tourism in
foreign countries becomes relatively more attractive.

The Puerto Rican economy is affected by a number of Commonwealth and
Federal investment incentive programs. For example, Section 936 of the
Internal Revenue Code provides for a credit against Federal income taxes
for U.S. companies operating on the island if certain requirements are
met. The Omnibus Budget Reconciliation Act of 1993 imposes limits on
such credit, effective for tax years beginning after 1993. In addition,
from time to time proposals are introduced in Congress which, if enacted
into law, would eliminate some or all of the benefits of Section 936.
Although no assessment can be made at this time of the precise effect of
such limitation, it is expected that the limitation of Section 936
credits would have a negative impact on Puerto Rico's economy.

The foregoing information constitutes only a brief summary of some of
the financial difficulties which may impact certain issuers of Bonds and
does not purport to be a complete or exhaustive description of all
adverse conditions to which the issuers of the Bonds are subject.
Additionally, many factors including national economic, social and
environmental policies and conditions, which are not within the control
of the issuers of Bonds, could affect or could have an adverse impact on
the financial condition of Puerto Rico and various agencies and
political subdivisions located in Puerto Rico. The Sponsor is unable to
predict whether or to what extent such factors or other factors may
affect the issuers of Bonds, the market value or marketability of the
Bonds or the ability of the respective issuers of the Bonds acquired by
the Trusts to pay interest on or principal of the Bonds.

Interest on certain of the Bonds in certain Arkansas, Idaho, Kansas,
Maine, Mississippi and Nebraska Trusts will be an item of tax preference
for purposes of the Alternative Minimum Tax ("AMT"). The investment by
non-AMT individual taxpayers in AMT municipal bonds generally results in
a higher yield to such bondholders than non-AMT municipal bonds. Since a
portion of the interest from certain Arkansas, Idaho, Kansas, Maine,
Mississippi and Nebraska Trusts is an AMT preference item, certain
Arkansas, Idaho, Kansas, Maine, Mississippi and Nebraska Trusts may be
more appropriate for investors who are not subject to AMT.

Investors should be aware that many of the Bonds in the Trusts are
subject to continuing requirements such as the actual use of Bond
proceeds or manner of operation of the project financed from Bond
proceeds that may affect the exemption of interest on such Bonds from
Federal income taxation. Although at the time of issuance of each of the
Bonds in the Trusts an opinion of bond counsel was rendered as to the
exemption of interest on such obligations from Federal income taxation,
there can be no assurance that the respective issuers or other obligors
on such obligations will fulfill the various continuing requirements

Page 7

established upon issuance of the Bonds. A failure to comply with such
requirements may cause a determination that interest on such obligations
is subject to Federal income taxation, perhaps even retroactively from
the date of issuance of such Bonds, thereby reducing the value of the
Bonds and subjecting Unit holders to unanticipated tax liabilities. 

Because certain of the Bonds may from time to time under certain
circumstances be sold or redeemed or will mature in accordance with
their terms and because the proceeds from such events will be
distributed to Unit holders and will not be reinvested, no assurance can
be given that a Trust will retain for any length of time its present
size and composition. Neither the Sponsor nor the Trustee shall be
liable in any way for any default, failure or defect in any Bond.
Certain of the Bonds contained in the Trusts may be subject to being
called or redeemed in whole or in part prior to their stated maturities
pursuant to optional redemption provisions, sinking fund provisions,
special or extraordinary redemption provisions or otherwise. A bond
subject to optional call is one which is subject to redemption or
refunding prior to maturity at the option of the issuer. A bond subject
to sinking fund redemption is one which is subject to partial call from
time to time at par or, in the case of a zero coupon bond, at the
accreted value from a fund accumulated for the scheduled retirement of a
portion of an issue prior to maturity. Special or extraordinary
redemption provisions may provide for redemption at par (or for original
issue discount bonds at issue price plus the amount of original issue
discount accreted to redemption date plus, if applicable, some premium)
of all or a portion of an issue upon the occurrence of certain
circumstances. The exercise of redemption or call provisions will
(except to the extent the proceeds of the called Bonds are used to pay
for Unit redemptions) result in the distribution of principal and may
result in a reduction in the amount of subsequent interest
distributions; it may also affect the long-term return and the current
return on Units of each Trust. Redemption pursuant to call provisions is
more likely to occur, and redemption pursuant to sinking fund provisions
may occur, when the Bonds have an offering side valuation which
represents a premium over par or for original issue discount bonds a
premium over the accreted value. Unit holders may recognize capital gain
or loss upon any redemption or call. 

To the best knowledge of the Sponsor, there is no litigation pending as
of the date hereof in respect of any Bonds which might reasonably be
expected to have a material adverse effect upon the Trusts. At any time
after the date hereof, litigation may be initiated on a variety of
grounds with respect to Bonds in a Trust. Such litigation, as for
example suits challenging the issuance of pollution control revenue
bonds under recently-enacted environmental protection statutes, may
affect the validity of such Bonds or the tax-free nature of the interest
thereon. While the outcome of litigation of such nature can never be
entirely predicted, the Fund has received opinions of bond counsel to
the issuing authority of each Bond on the date of issuance to the effect
that such Bonds have been validly issued and that the interest thereon
is exempt from Federal income taxes and state and local taxes. In
addition, other factors may arise from time to time which potentially
may impair the ability of issuers to meet obligations undertaken with
respect to the Bonds.

What are Estimated Long-Term Return and Estimated Current Return?

At the date of this Prospectus, the Estimated Current Return and the
Estimated Long-Term Return, under the monthly, quarterly (if applicable)
and semi-annual (if applicable) distribution plans, are as set forth in
Part One attached hereto for each Trust. Estimated Current Return is
computed by dividing the Estimated Net Annual Interest Income per Unit
by the Public Offering Price. Any change in either amount will result in
a change in the Estimated Current Return. For each Trust, the Public
Offering Price will vary in accordance with fluctuations in the prices
of the underlying Bonds and the Net Annual Interest Income per Unit will
change as Bonds are redeemed, paid, sold or exchanged in certain
refundings or as the expenses of each Trust change. Therefore, there is
no assurance that the Estimated Current Return indicated in Part One for

Page 8

each Trust will be realized in the future. Estimated Long-Term Return is
calculated using a formula which (1) takes into consideration and
determines and factors in the relative weightings of the market values,
yields (which take into account the amortization of premiums and the
accretion of discounts) and estimated retirements of all of the Bonds in
the Trust and (2) takes into account a compounding factor, the expenses
and sales charge associated with each Unit of a Trust. Since the market
values and estimated retirements of the Bonds and the expenses of the
Trust will change, there is no assurance that the Estimated Long-Term
Return indicated in Part One for each Trust will be realized in the
future. Estimated Current Return and Estimated Long-Term Return are
expected to differ because the calculation of Estimated Long-Term Return
reflects the estimated date and amount of principal returned while
Estimated Current Return calculations include only Net Annual Interest
Income and Public Offering Price. Neither rate reflects the true return
to Unit holders, which is lower, because neither includes the effect of
certain delays in distributions to Unit holders.

A comparison of tax-free and equivalent taxable estimated current
returns and estimated long-term returns with the returns on various
taxable investments is one element to consider in making an investment
decision. The Sponsor may from time to time in its advertising and sales
materials compare the then current estimated returns on the Trust and
returns over specified periods on other similar Trusts sponsored by Nike
Securities L.P. with returns on taxable investments such as corporate or
U.S. Government bonds, bank CDs and money market accounts or money
market funds, each of which has investment characteristics that may
differ from those of the Trust.

How are Purchased Interest and Accrued Interest Treated?

Purchased Interest. For The First Trust Combined Series 198-208, each
Trust contains an amount of Purchased Interest. Purchased Interest is a
portion of the unpaid interest that has accrued on the Bonds from the
later of the last payment date on the Bonds or the date of issuance
thereof through the First Settlement Date and is included in the
calculation of the Public Offering Price. Purchased Interest will be
distributed to Unit holders as Units are redeemed or Securities are
sold, mature or are called. See "Summary of Essential Information"
appearing in Part One for each Trust for the amount of Purchased
Interest per Unit for each Trust. Purchased Interest is an element of
the determination of the price Unit holders will receive in connection
with the sale or redemption of Units prior to the termination of the
Trust.

Accrued Interest. Accrued interest is the accumulation of unpaid
interest on a bond from the last day on which interest thereon was paid.
Interest on Bonds generally is paid semi-annually, although each Trust
accrues such interest daily. Because of this, a Trust always has an
amount of interest earned but not yet collected by the Trustee. For this
reason, with respect to sales settling subsequent to the First
Settlement Date, the Public Offering Price of Units will have added to
it the proportionate share of accrued interest to the date of
settlement. Unit holders will receive on the next distribution date of
the Trust the amount, if any, of accrued interest paid on their Units.

For The First Trust Combined Series 1-197, except through an advancement
of its own funds, the Trustee has no cash for distribution to Unit
holders until it receives interest payments on the Bonds in a Trust. The
Trustee will recover its advancements without interest or other costs to
such Trust from interest received on the Bonds in the Trust. When these
advancements have been recovered, regular distributions of interest to
Unit holders will commence. See "Rights of Unit Holders-How are Interest
and Principal Distributed?" Interest account balances are established
with generally positive cash balances so that it will not be necessary
on a regular basis for the Trustee to advance its own funds in
connection with interest distributions.

For The First Trust Combined Series 198-208, in an effort to reduce the
amount of Purchased Interest which would otherwise have to be paid by
Unit holders, the Trustee may advance a portion of the accrued interest
to the Sponsor as the Unit holder of record as of the First Settlement
Date. Consequently, the amount of accrued interest to be added to the
Public Offering Price of Units will include only accrued interest from
the First Settlement Date to the date of settlement (other than the
Purchased Interest already included therein), less any distributions
from the Interest Account subsequent to the First Settlement Date. See
"Rights of Unit Holders-How are Interest and Principal Distributed?"

For The First Trust Combined Series 209 and subsequent Series, in an
effort to reduce the amount of accrued interest which would otherwise
have to be paid in addition to the Public Offering Price in the sale of
Units to the public, the Trustee will advance the amount of accrued
interest as of the First Settlement Date and the same will be
distributed to the Sponsor as the Unit holder of record as of the First
Settlement Date. Consequently, the amount of accrued interest to be
added to the Public Offering Price of Units will include only accrued
interest from the First Settlement Date to the date of settlement, less
any distributions from the Interest Account subsequent to the First
Settlement Date. See "Rights of Unit Holders-How are Interest and
Principal Distributed?"

Page 9


Because of the varying interest payment dates of the Bonds, accrued
interest at any point in time will be greater than the amount of
interest actually received by a Trust and distributed to Unit holders.
If a Unit holder sells or redeems all or a portion of his Units, he will
be entitled to receive his proportionate share of the Purchased Interest
(if any) and accrued interest from the purchaser of his Units. Since the
Trustee has the use of the funds (including Purchased Interest, if any)
held in the Interest Account for distributions to Unit holders and since
such Account is non-interest-bearing to Unit holders, the Trustee
benefits thereby.

Why and How are the Insured Trusts Insured?

THE FOLLOWING DISCUSSION IS APPLICABLE ONLY TO THE INSURED TRUSTS. THE
BONDS IN THE PORTFOLIO OF AN ADVANTAGE TRUST ARE NOT INSURED BY
INSURANCE OBTAINED BY THE FUND.

All Bonds in the portfolio of an Insured Trust are insured as to the
scheduled payment of interest and principal by policies obtained by each
Insured Trust from Financial Guaranty Insurance Company ("Financial
Guaranty" or "FGIC"), a New York stock insurance company, or AMBAC
Indemnity Corporation ("AMBAC Indemnity" or "AMBAC"), a Wisconsin-
domiciled stock insurance company, or obtained by the Bond issuer, the
underwriters, the Sponsor or others prior to the Initial Date of Deposit
directly from Financial Guaranty, AMBAC Indemnity or other insurers (the
"Preinsured Bonds"). The insurance policy obtained by each Insured Trust
is noncancellable and will continue in force for such Trust so long as
such Trust is in existence and the Bonds described in the policy
continue to be held by such Trust (see "Portfolio" for each Insured
Trust). Nonpayment of premiums on the policy obtained by each Insured
Trust will not result in the cancellation of insurance, but will permit
Financial Guaranty and/or AMBAC Indemnity to take action against the
Trustee to recover premium payments due it. Premium rates for each issue
of Bonds protected by the policy obtained by each Insured Trust are
fixed for the life of such Trust. The premium for any Preinsured Bonds
has been paid in advance by the Bond issuer, the underwriters, the
Sponsor or others and any such policy or policies are noncancellable and
will continue in force so long as the Bonds so insured are outstanding
and the insurer and/or insurers thereof remain in business. If the
provider of an original issuance insurance policy is unable to meet its
obligations under such policy, or if the rating assigned to the claims-
paying ability of such insurer deteriorates, Financial Guaranty and/or
AMBAC Indemnity has no obligation to insure any issue adversely affected
by either of the above described events. A monthly premium is paid by
each Insured Trust for the insurance obtained by such Trust, which is
payable from the interest income received by such Trust. In the case of
Preinsured Bonds, no premiums for insurance are paid by the Insured Trust.

Financial Guaranty Insurance Company. Under the provisions of the
aforementioned portfolio insurance issued by Financial Guaranty,
Financial Guaranty unconditionally and irrevocably agrees to pay to
Citibank, N.A., or its successor, as its agent (the "Fiscal Agent"),
that portion of the principal of and interest on the Bonds covered by
the policy which shall become due for payment but shall be unpaid by
reason of nonpayment by the issuer of the Bonds. The term "due for
payment" means, when referring to the principal of a Bond, its stated
maturity date or the date on which it shall have been called for
mandatory sinking fund redemption and does not refer to any earlier date
on which payment is due by reason of call for redemption (other than by
mandatory sinking fund redemption), acceleration or other advancement of
maturity and means, when referring to interest on a Bond, the stated
date for payment of interest, except that when the interest on a Bond
shall have been determined, as provided in the underlying documentation
relating to such Bond, to be subject to Federal income taxation, "due
for payment" also means, when referring to the principal of such Bond,
the date on which such Bond has been called for mandatory redemption as
a result of such determination of taxability, and when referring to
interest on such Bond, the accrued interest at the rate provided in such
documentation to the date on which such Bond has been called for such
mandatory redemption, together with any applicable redemption premium.
The term "due for payment" will not include, when referring to either
the principal of a Bond or the interest on a Bond, any acceleration of
payment unless such acceleration is at the sole option of Financial
Guaranty.

Financial Guaranty will make such payments to the Fiscal Agent on the
date such principal or interest becomes due for payment or on the
business day next following the day on which Financial Guaranty shall
have received notice of nonpayment, whichever is later. The Fiscal Agent
will disburse to the Trustee the face amount of principal and interest
which is then due for payment but is unpaid by reason of nonpayment by

Page 10

the issuer but only upon receipt by the Fiscal Agent of (i) evidence of
the Trustee's right to receive payment of the principal or interest due
for payment and (ii) evidence, including any appropriate instruments of
assignment, that all of the rights to payment of such principal or
interest due for payment shall thereupon vest in Financial Guaranty.
Upon such disbursement, Financial Guaranty shall become the owner of the
Bond, appurtenant coupon or right to payment of principal or interest on
such Bond and shall be fully subrogated to all of the Trustee's rights
thereunder, including the right to payment thereof.

Pursuant to an irrevocable commitment of Financial Guaranty, the
Trustee, upon the sale of a Bond covered under a policy obtained by an
Insured Trust has the right to obtain permanent insurance with respect
to such Bond (i.e., insurance to maturity of the Bonds regardless of the
identity of the holder thereof) (the "Permanent Insurance") upon the
payment of a single predetermined insurance premium from the proceeds of
the sale of such Bond. Accordingly, any Bond in an Insured Trust is
eligible to be sold on an insured basis. It is expected that the Trustee
will exercise the right to obtain Permanent Insurance only if upon such
exercise the Insured Trust would receive net proceeds (sale of Bond
proceeds less the insurance premium attributable to the Permanent
Insurance) from such sale in excess of the sale proceeds if such Bonds
were sold on an uninsured basis. The insurance premium with respect to
each Bond eligible for Permanent Insurance is determined based upon the
insurability of each Bond as of the Initial Date of Deposit and will not
be increased or decreased for any change in the creditworthiness of such
Bond.

Financial Guaranty is a wholly-owned subsidiary of FGIC Corporation (the
"Corporation"), a Delaware holding company. The Corporation is a wholly-
owned subsidiary of General Electric Capital Corporation ("GECC").
Neither the Corporation nor GECC is obligated to pay the debts of or the
claims against Financial Guaranty. Financial Guaranty is domiciled in
the State of New York and is subject to regulation by the State of New
York Insurance Department. As of December 31, 1996, the total capital
and surplus of Financial Guaranty was approximately $1,093,256,000.

In addition, Financial Guaranty is currently licensed to write insurance
in all fifty states and the District of Columbia.

The information relating to Financial Guaranty contained above has been

herein with respect to such corporation is unaudited but appears in

authorities and is subject to audit and review by such authorities. No
representation is made herein as to the accuracy or adequacy of such
information or as to the absence of material adverse changes in such
information subsequent to the date thereof.

AMBAC Indemnity Corporation ("AMBAC Indemnity"). The Insurance Policy of
AMBAC Indemnity obtained by an Insured Trust is noncancellable and will
continue in force for so long as the Bonds described in the Insurance
Policy are held by an Insured Trust. A monthly premium is paid by an
Insured Trust for the Insurance Policy obtained by it. The Trustee will
pay, when due, successively, the full amount of each installment of the
insurance premium. Pursuant to a binding agreement with AMBAC Indemnity,
in the event of a sale of a Bond covered by the AMBAC Indemnity
Insurance Policy, the Trustee has the right to obtain permanent
insurance for such Bond upon payment of a single predetermined premium
from the proceeds of the sale of such Bond. 

Under the terms of the Insurance Policy, AMBAC Indemnity agrees to pay
to the Trustee that portion of the principal of and interest on the
Bonds insured by AMBAC Indemnity which shall become due for payment but
shall be unpaid by reason of nonpayment by the issuer of the Bonds. The
term "due for payment" means, when referring to the principal of a Bond
so insured, its stated maturity date or the date on which it shall have
been called for mandatory sinking fund redemption and does not refer to
any earlier date on which payment is due by reason of call for
redemption (other than by mandatory sinking fund redemption),
acceleration or other advancement of maturity and means, when referring
to interest on a Bond, the stated date for payment of interest.

Page 11


AMBAC Indemnity will make payment to the Trustee not later than thirty
days after notice from the Trustee is received by AMBAC Indemnity that a
nonpayment of principal or of interest on a Bond has occurred, but not
earlier than the date on which the Bonds are due for payment. AMBAC
Indemnity will disburse to the Trustee the face amount of principal and
interest which is then due for payment but is unpaid by reason of
nonpayment by the issuer in exchange for delivery of Bonds, not less in
face amount than the amount of the payment in bearer form, free and
clear of all liens and encumbrances and uncancelled. In cases where
Bonds are issuable only in a form whereby principal is payable to
registered holders or their assigns, AMBAC Indemnity shall pay principal
only upon presentation and surrender of the unpaid Bonds uncancelled and
free of any adverse claim, together with an instrument of assignment in
satisfactory form, so as to permit ownership of such Bonds to be
registered in the name of AMBAC Indemnity or its nominee. In cases where
Bonds are issuable only in a form whereby interest is payable to
registered holders or their assigns, AMBAC Indemnity shall pay interest
only upon presentation of proof that the claimant is the person entitled
to the payment of interest on the Bonds and delivery of an instrument of
assignment, in satisfactory form, transferring to AMBAC Indemnity all
right under such Bonds to receive the interest in respect of which the
insurance payment was made.

AMBAC Indemnity is a Wisconsin-domiciled stock insurance corporation
regulated by the Office of the Commissioner of Insurance of the State of
Wisconsin and licensed to do business in fifty states, the District of
Columbia and the Commonwealth of Puerto Rico, with admitted assets of
approximately $2,550,327,507 (unaudited) and statutory capital of
approximately $1,446,559,894 (unaudited) as of December 31, 1996.
Statutory capital consists of AMBAC Indemnity's policyholders' surplus
and statutory contingency reserve. AMBAC Indemnity is a wholly owned
subsidiary of AMBAC Inc., a 100% publicly-held company. Moody's
Investors Service, Inc. and Standard & Poor's have both assigned a
triple-A claims-paying ability rating to AMBAC Indemnity.

Copies of AMBAC Indemnity's financial statements prepared in accordance
with statutory accounting standards are available from AMBAC Indemnity.
The address of AMBAC Indemnity's administrative offices and its
telephone number are One State Street Plaza, 17th Floor, New York, New
York 10004 and (212) 668-0340.

The information relating to AMBAC Indemnity contained above has been
furnished by AMBAC Indemnity. No representation is made herein as to the
accuracy or adequacy of such information, or as to the existence of any
adverse changes in such information, subsequent to the date hereof.

In determining whether to insure bonds, Financial Guaranty and/or AMBAC
Indemnity has applied its own standards which are not necessarily the
same as the criteria used in regard to the selection of bonds by the
Sponsor. This decision is made prior to the Initial Date of Deposit, as
bonds not covered by such insurance are not deposited in an Insured
Trust, unless such bonds are Preinsured Bonds. The insurance obtained by
an Insured Trust covers Bonds deposited in such Trust and physically
delivered to the Trustee in the case of bearer bonds or registered in
the name of the Trustee or its nominee or delivered along with an
assignment in the case of registered bonds or registered in the name of
the Trustee or its nominee in the case of Bonds held in book-entry form.
Contracts to purchase Bonds are not covered by the insurance obtained by
an Insured Trust although Bonds underlying such contracts are covered by
insurance upon physical delivery to the Trustee.

Insurance obtained by each Insured Trust or by the Bond issuer, the
underwriters, the Sponsor or others does not guarantee the market value
of the Bonds or the value of the Units of such Trust. The insurance
obtained by an Insured Trust is effective only as to Bonds owned by and
held in such Trust. In the event of a sale of any such Bond by the
Trustee, the insurance terminates as to such Bond on the date of sale.
In the event of a sale of a Bond insured by an Insured Trust, the
Trustee has the right to obtain Permanent Insurance upon the payment of
an insurance premium from the proceeds of the sale of such Bond. Except
as indicated below, insurance obtained by an Insured Trust has no effect
on the price or redemption value of Units. It is the present intention
of the Evaluator to attribute a value to such insurance obtained by an
Insured Trust (including the right to obtain Permanent Insurance) for
the purpose of computing the price or redemption value of Units only if
the Bonds covered by such insurance are in default in payment of
principal or interest or, in the Sponsor's opinion, in significant risk
of such default. The value of the insurance will be equal to the
difference between (i) the market value of a Bond which is in default in

Page 12

payment of principal or interest or in significant risk of such default
assuming the exercise of the right to obtain Permanent Insurance (less
the insurance premium attributable to the purchase of Permanent
Insurance) and (ii) the market value of such Bonds not covered by
Permanent Insurance. See "Public Offering-How is the Public Offering
Price Determined?" herein for a more complete description of the
Evaluator's method of valuing defaulted Bonds and Bonds which have a
significant risk of default. Insurance on a Preinsured Bond is effective
as long as such Bond is outstanding. Therefore, any such insurance may
be considered to represent an element of market value in regard to the
Bonds thus insured, but the exact effect, if any, of this insurance on
such market value cannot be predicted.

A contract of insurance obtained by an Insured Trust and the
negotiations in respect thereof represent the only relationship between
Financial Guaranty and/or AMBAC Indemnity and the Fund. Otherwise
neither Financial Guaranty nor its parent, FGIC Corporation, or any
affiliate thereof, nor AMBAC Indemnity nor its parent, AMBAC, Inc., or
any affiliate thereof has any significant relationship, direct or
indirect, with the Fund or the Sponsor, except that the Sponsor has in
the past and may from time to time in the future, in the normal course
of its business, participate as sole underwriter or as manager or as a
member of underwriting syndicates in the distribution of new issues of
municipal bonds in which the investors or the affiliates of FGIC
Corporation and/or AMBAC Inc. have or will be participants or for which
a policy of insurance guaranteeing the scheduled payment of interest and
principal has been obtained from Financial Guaranty and/or AMBAC
Indemnity. Neither the Fund nor the Units of a Trust nor the portfolio
of such Trust is insured directly or indirectly by FGIC Corporation
and/or AMBAC Inc.

MBIA Insurance Corporation. MBIA Insurance Corporation ("MBIA
Corporation" or "MBIA") is the principal operating subsidiary of MBIA,
Inc., a New York Stock Exchange listed company. MBIA, Inc. is not
obligated to pay the debts of or claims against MBIA Corporation. MBIA
Corporation is domiciled in the State of New York and licensed to do

United States and the Territory of Guam. MBIA has two European branches,
one in the Republic of France and the other in the Kingdom of Spain. New
York has laws prescribing minimum capital requirements, limiting classes
and concentrations of investments and requiring the approval of policy
rates and forms. State laws also regulate the amount of both the
aggregate and individual risks that may be insured, the payment of
dividends by the insurer, changes in control and transactions among
affiliates. Additionally, the Insurer is required to maintain
contingency reserves on its liabilities in certain amounts and for
certain periods of time.

As of December 31, 1995, MBIA had admitted assets of $3.8 billion
(audited), total liabilities of $2.5 billion (audited), and total
capital and surplus of $1.3 billion (audited) determined in accordance
with statutory accounting practices prescribed or permitted by insurance
regulatory authorities. As of December 31, 1996, MBIA had admitted
assets of $4.5 billion (audited), total liabilities of $3.0 billion
(audited), and total capital and surplus of $1.3 billion (audited),
determined in accordance with statutory accounting practices prescribed
or permitted by insurance regulatory authorities. Copies of MBIA's
financial statements prepared in accordance with statutory accounting
practices are available from MBIA. The address of MBIA is 113 King
Street, Armonk, New York 10504.

Effective December 31, 1989, MBIA Inc. acquired Bond Investors Group,
Inc. On January 5, 1990, MBIA acquired all of the outstanding stock of
Bond Investors Group, Inc., the parent of Bond Investors Guaranty
Insurance Company (BIG), now known as MBIA Insurance Corp. of Illinois.
Through a reinsurance agreement, BIG has ceded all of its net insured
risks, as well as its unearned premium and contingency reserves, to MBIA
and MBIA has reinsured BIG's net outstanding exposure.

Moody's Investors Service rates all bond issues insured by MBIA "Aaa"
and short-term loans "MIG 1," both designated to be of the highest
quality. Standard & Poor's rates all new issues insured by MBIA "AAA."

Capital Guaranty Insurance Company. On December 20, 1995, Capital
Guaranty Corporation ("CGC") merged with a subsidiary of Financial
Security Assurance Holdings Ltd. and Capital Guaranty Insurance Company,
CGC's principal operating subsidiary, changed its name to Financial
Security Assurance of Maryland Inc. ("FSA Maryland") and became a wholly-
owned subsidiary of Financial Security Assurance Inc. For further
description, see "Financial Security Assurance Inc." herein. The address
of FSA Maryland and its telephone number are Steuart Tower, One Market

CapMAC. CapMAC is a New York-domiciled monoline stock insurance company
which engages only in the business of financial guarantee and surety
insurance. CapMAC is licensed in 49 states in addition to the District
of Columbia, the Commonwealth of Puerto Rico and the territory of Guam.
CapMAC insures structured asset-backed, corporate and other financial
obligations in the domestic and foreign capital markets. CapMAC may also
provide financial guarantee reinsurance for structured asset-backed,
corporate and municipal obligations written by other major insurance
companies.

CapMAC's claims-paying ability is rated "Aaa" by Moody's Investors
Service, Inc. ("Moody's"), "AAA" by Standard & Poor's, and "AAA" by Duff
& Phelps, Inc. ("Duff & Phelps"). Such ratings reflect only the views of
the respective rating agencies, are not recommendations to buy, sell or
hold securities and are subject to revision or withdrawal at any time by
such rating agencies.

CapMAC is wholly owned by CapMAC Holdings Inc. ("Holdings"), a company
that is owned by a group of institutional and other investors, including
CapMAC's management and employees. CapMAC commenced operations on
December 24, 1987 as an indirect, wholly-owned subsidiary of Citibank
(New York State), a wholly-owned subsidiary of Citicorp. On June 25,
1992, Citibank (New York State) sold CapMAC to Holdings (the "Sale").

Neither Holdings nor any of its stockholders is obligated to pay any
claims under any surety bond issued by CapMAC or any debts of CapMAC or
to make additional capital contributions.

CapMAC is regulated by the Superintendent of Insurance of the State of
New York. In addition, CapMAC is subject to regulation by the insurance
departments of the other jurisdictions in which it is licensed. CapMAC
is subject to periodic regulatory examinations by the same regulatory
authorities.

CapMAC is bound by insurance laws and regulations regarding capital
transfers, limitations upon dividends, investment of assets, changes in
control, transactions with affiliates and consolidations and
acquisitions. The amount of exposure per risk that CapMAC may retain,
after giving effect to reinsurance, collateral or other securities, is
also regulated. Statutory and regulatory accounting practices may
prescribe appropriate rates at which premiums are earned and the levels
of reserves required. In addition, various insurance laws restrict the
incurrence of debt, regulate permissible investments of reserves,
capital and surplus, and govern the form of surety bonds.

CapMAC's obligations under the Surety Bond(s) may be reinsured. Such
reinsurance does not relieve CapMAC of any of its obligations under the
Surety Bond(s).

THE SURETY BONDS ARE NOT COVERED BY THE PROPERTY/CASUALTY INSURANCE
SECURITY FUND SPECIFIED IN ARTICLE 76 OF THE NEW YORK INSURANCE LAW.

In connection with the Sale, Holdings and CapMAC entered into an
Ownership Policy Agreement (the "Ownership Policy Agreement"), which
sets forth Holdings' intent with respect to its ownership and control of
CapMAC and provides for certain policies and agreements with respect to
Holdings' exercise of its control of CapMAC. In the Ownership Policy
Agreement, Holdings has agreed that, during the term of the Ownership
Policy Agreement, it will not and will not permit any stockholder of
Holdings to enter into any transaction the result of which would be a
change of control (as defined in the Ownership Policy Agreement) of
CapMAC, unless the long-term debt obligations or claims-paying ability
of the person which would control CapMAC after such transaction or its
direct or indirect parent are rated in a high investment grade category,
unless Holdings or CapMAC has confirmed that CapMAC's claims-paying
ability rating by Moody's (the "Rating") in effect immediately prior to
any such change of control will not be downgraded by Moody's upon such
change of control or unless such change of control occurs as a result of
a public offering of Holdings' capital stock.

In addition, the Ownership Policy Agreement includes agreements (i) not
to change the "zero-loss" underwriting standards or policies and
procedures of CapMAC in a manner that would materially and adversely
affect the risk profile of CapMAC's book of business, (ii) that CapMAC
will adhere to the aggregate leverage limitations and maintain
capitalization levels considered by Moody's from time to time as
consistent with maintaining CapMAC's Rating and (iii) that until
CapMAC's statutory capital surplus and contingency reserve ("qualified
statutory capital") equal $250 million, CapMAC will maintain a specified
amount of qualified statutory capital in excess of the amount of
qualified statutory capital that CapMAC is required at such time to

Page 14

maintain under the aggregate leverage limitations set forth in Article
69 of the New York Insurance Law.

The Ownership Policy Agreement will terminate on the earlier of the date
on which a change of control of CapMAC occurs and the date on which
CapMAC and Holdings agree in writing to terminate the Ownership Policy
Agreement; provided that, CapMAC or Holdings has confirmed that CapMAC's
Rating in effect immediately prior to any such termination will not be
downgraded upon such termination.

As of December 31, 1996, CapMAC had statutory capital and surplus of
approximately $260,217,105 and had not incurred any debt obligations.
Article 69 of the New York State Insurance Law requires that CapMAC
establishes and maintains the contingency reserve.

Copies of CapMAC's financial statements prepared in accordance with
statutory accounting standards, which differ from generally accepted
accounting principles, and filed with the Insurance Department of the
State of New York are available upon request. CapMAC is located at 885
Third Avenue, New York, New York 10022, and its telephone number is

Financial Security Assurance. Financial Security Assurance Inc.
("Financial Security") is a monoline insurance company incorporated in
1984 under the laws of the State of New York. Financial Security is
licensed to engage in the financial guaranty insurance business in all
50 states, the District of Columbia and Puerto Rico.

Financial Security and its subsidiaries are engaged in the business of
writing financial guaranty insurance, principally in respect of
securities offered in domestic and foreign markets. In general,
financial guaranty insurance consists of the issuance of a guaranty of
scheduled payments of an issuer's securities, thereby enhancing the
credit rating of those securities, in consideration for payment of a
premium to the insurer. Financial Security and its subsidiaries
principally insure asset-backed, collateralized and municipal
securities. Asset-backed securities are generally supported by
residential mortgage loans, consumer or trade receivables, securities or
other assets having an ascertainable cash flow or market value.
Collateralized securities include public utility first mortgage bonds
and sale/leaseback obligation bonds. Municipal securities consist
largely of general obligation bonds, special revenue bonds and other
special obligations of state and local governments. Financial Security
insures both newly issued securities sold in the primary market and
outstanding securities sold in the secondary market that satisfy
Financial Security's underwriting criteria.

Financial Security is a wholly-owned subsidiary of Financial Security
Assurance Holdings Ltd. ("Holdings"), a New York Stock Exchange listed
company. Major shareholders of Holdings include Fund American
Enterprises Holdings, Inc., U S West Capital Corporation and The Tokio
Marine and Fire Insurance Co. Ltd. No shareholder of Financial Security
is obligated to pay any debt of Financial Security or its subsidiaries
or any claim under any insurance policy issued by Financial Security or
its subsidiaries or to make any additional contribution to the capital
of Financial Security or its subsidiaries. As of December 31, 1996, the
total policyholders' surplus and contingency reserves and the total
unearned premium reserve, respectively, of Financial Security and its
consolidated subsidiaries were, in accordance with statutory accounting
principles, approximately $675,944,000 (unaudited) and $411,732,000
(unaudited), and the total shareholders' equity and the unearned premium
reserve, respectively, of Financial Security and its consolidated
subsidiaries were, in accordance with generally accepted accounting
principles, approximately $815,332,000 (audited), and $359,972,000
(audited). Copies of Financial Security's financial statements may be
obtained by writing to Financial Security at 350 Park Avenue, New York,
New York, 10022, Attention Communications Department. Financial
Security's telephone number is (212) 826-0100.

Pursuant to an intercompany agreement, liabilities on financial guaranty
insurance written or reinsured from third parties by Financial Security
or any of its domestic operating insurance company subsidiaries
(including FSA Maryland) are reinsured among such companies on an agreed-
upon percentage substantially proportional to their respective capital,
surplus and reserves, subject to applicable statutory risk limitations.
In addition, Financial Security and FSA Maryland reinsure a portion of
their liabilities under certain of their financial guaranty insurance
policies with other reinsurers under various quota share treaties and on
a transaction-by-transaction basis. Such reinsurance is utilized as a
risk management device and to comply with certain statutory and rating
agency requirements; it does not alter or limit the obligations of
Financial Security or FSA Maryland under any financial guaranty
insurance policy.

Page 15


The claims-paying ability of Financial Security and FSA Maryland is
rated "Aaa" by Moody's Investors Service, Inc., and "AAA" by Standard &
Poor's Rating Services, Nippon Investors Service Inc. and Standard &
Poor's (Australia) Pty. Ltd. Such ratings reflect only the views of the
respective rating agencies, are not recommendations to buy, sell or hold
securities and are subject to revision or withdrawal at any time by such
rating agencies.

Connie Lee Insurance Company. Connie Lee Insurance Company ("Connie
Lee"), a stock insurance company incorporated in Wisconsin, is a wholly-
owned subsidiary of College Construction Loan Insurance Association
("CCLIA"), a stockholder-owned District of Columbia insurance holding
company whose creation was authorized by the 1986 amendments to the
Higher Education Act. The United States Department of Education ("DOE")
and Student Loan Marketing Association ("Sallie Mae") are founding
shareholders of College Construction Loan Insurance Association. Connie
Lee is not an agency or instrumentality of the United States Government,
although the United States Government is a stockholder of CCLIA. The
obligations of Connie Lee are not obligations of the United States
Government. As a federally authorized company, Connie Lee's structure
and operational authorities are subject to revision by amendments to the
Higher Education Act or other federal enactments.

Various bills containing provisions relating to the privatization of
Connie Lee ("Connie Lee Privatization Legislation") are pending in the
United States Congress. If enacted in the form included in these bills,
the Connie Lee Privatization Legislation would, among other things,
remove the restrictions that limit the types of obligations Connie Lee
is permitted to insure and would authorize Connie Lee to engage in any
business appropriate for any other fully private corporation. The Connie
Lee Privatization Legislation would also provide for the disposition of
the stock in CCLIA held by DOE and for the repeal of substantially all
of the provisions of the Higher Education Act pertaining to the
structure and other operational authorities of Connie Lee. While one
bill containing the Connie Lee Privatization Legislation was passed by
the House of Representatives in September of 1995 and companion
legislation has been introduced in the Senate, it cannot be predicted
whether, or in what form, the Connie Lee Privatization Legislation or
other federal legislation affecting Connie Lee will ultimately be
enacted into law, or the effect that any such enactment may ultimately
have on Connie Lee.

As of December 31, 1996, the total policyholders' surplus of Connie Lee
was $110,443,108 (unaudited) and total admitted assets were $232,533,675
(unaudited), as reported to the Commissioner of Insurance of the State
of Wisconsin in Connie Lee's financial statements prepared in accordance
with statutory accounting principles applicable to insurance companies.
Copies of these financial statements are available from Connie Lee upon
request.

CCLIA's consolidated annual (audited) and quarterly (unaudited)
financial statements prepared in accordance with generally accepted
accounting principles are filed periodically with the Nationally
Recognized Municipal Securities Information Repositories designated
under Rule 15c2-12 of the Securities and Exchange Commission. The
information contained in these financial statements is incorporated
herein by reference. Copies of these financial statements are available
from Connie Lee upon request.

Standard & Poor's has rated the claims-paying ability of Connie Lee "AAA".

Connie Lee makes no representation regarding the Bonds or the
advisability of investing in the Bonds. The above rating is not a
recommendation to buy, sell or hold the Connie Lee insured Bonds and
such rating is subject to the revision or withdrawal at any time by the
rating agency. Any downward revision or withdrawal of the rating may
have an adverse effect on the market price of the Connie Lee insured
Bonds.

The address of Connie Lee's administrative offices and its telephone
number are 1299 Pennsylvania Avenue, N.W., Washington, D.C. 20004 and
(202) 835-0090.

Because the Bonds in each Insured Trust are insured as to the scheduled
payment of principal and interest and on the basis of the financial
condition of the insurance companies referred to above, Standard &
Poor's has assigned to units of each Insured Trust its "AAA" investment
rating. This is the highest rating assigned to securities by Standard &
Poor's. See "Description of Bond Ratings." The obtaining of this rating
by each Insured Trust should not be construed as an approval of the
offering of the Units by Standard & Poor's or as a guarantee of the
market value of each Insured Trust or the Units of such Trust. Standard
& Poor's has indicated that this rating is not a recommendation to buy,
hold or sell Units nor does it take into account the extent to which
expenses of each Trust or sales by each Trust of Bonds for less than the

Page 16

purchase price paid by such Trust will reduce payment to Unit holders of
the interest and principal required to be paid on such Bonds. Such
rating will be in effect for a period of thirteen months from the
Initial Date of Deposit of an Insured Trust and will, unless renewed,
terminate at the end of such period. There is no guarantee that the
"AAA" investment rating with respect to the Units of an Insured Trust
will be maintained.

An objective of portfolio insurance obtained by such Insured Trust is to
obtain a higher yield on the Bonds in the portfolio of such Trust than
would be available if all the Bonds in such portfolio had the Standard &
Poor's "AAA" and/or Moody's Investors Service, Inc. "Aaa" rating(s) and
at the same time to have the protection of insurance of scheduled
payment of interest and principal on the Bonds. There is, of course, no
certainty that this result will be achieved. Bonds in a Trust for which
insurance has been obtained by the Bond issuer, the underwriters, the
Sponsor or others (all of which were rated "AAA" by Standard & Poor's
and/or "Aaa" by Moody's Investors Service, Inc.) may or may not have a
higher yield than uninsured bonds rated "AAA" by Standard & Poor's or
"Aaa" by Moody's Investors Service, Inc. In selecting Bonds for the
portfolio of each Insured Trust, the Sponsor has applied the criteria
herein before described.

What is the Federal Tax Status of Unit Holders?

See Part Three for each Trust.

FOR INFORMATION WITH RESPECT TO EXEMPTION FROM STATE OR OTHER LOCAL
TAXES, SEE PART THREE FOR EACH TRUST.

What are the Expenses and Charges?

With the exception of bookkeeping and other administrative services
provided to the Trusts, for which the Sponsor will be reimbursed in
amounts as set forth under "Special Trust Information" in each Part One
of this Prospectus, the Sponsor will not receive any fee in connection
with its activities relating to the Trusts. For Series 49 and all
subsequent Series, First Trust Advisors L.P., an affiliate of the
Sponsor, will receive an annual supervisory fee, which is not to exceed
the amount set forth in Part One for each Trust, for providing portfolio
supervisory services for the Trust. Such fee is based on the number of
Units outstanding in each Trust on January 1 of each year except for
Trusts which were established subsequent to the last January 1, in which
case the fee will be based on the number of Units outstanding in such
Trusts as of the respective Initial Dates of Deposit.

For each valuation of the Bonds in a Trust, the Evaluator will receive a
fee as indicated in Part One of this Prospectus. The Trustee pays
certain expenses of each Trust for which it is reimbursed by such Trust.

The Trustee will receive for its ordinary recurring services to a Trust
an annual fee computed as indicated in Part One of this Prospectus. For
a discussion of the services performed by the Trustee pursuant to its
obligations under the Indenture, reference is made to the material set
forth under "Rights of Unit Holders."

The Trustee's and Evaluator's fees are payable monthly on or before each
Distribution Date from the Interest Account of each Trust to the extent
funds are available and then from the Principal Account of such Trust.
Since the Trustee has the use of the funds being held in the Principal
and Interest Accounts for future distributions, payment of expenses and
redemptions and since such Accounts are non-interest-bearing to Unit
holders, the Trustee benefits thereby. Part of the Trustee's
compensation for its services to the Fund is expected to result from the
use of these funds. However, the Trustee may bear from its own resources
certain expenses relating to a Trust.

Each of the above mentioned fees may be increased without approval of
the Unit holders by amounts not exceeding proportionate increases under
the category "All Services Less Rent of Shelter" in the Consumer Price
Index published by the United States Department of Labor. In addition,
with respect to the fees payable to the Sponsor or an affiliate of the
Sponsor for providing bookkeeping and other administrative services and
supervisory services, such individual fees may exceed the actual costs
of providing such services for a Trust, but at no time will the total
amount received for such Services rendered to all unit investment trusts
of which Nike Securities L.P. is the Sponsor in any calendar year exceed
the actual cost to the Sponsor or its affiliate of supplying such
services in such year.

The annualized cost of the portfolio insurance obtained by the Fund for
each Insured Trust is indicated in Part One for each Trust in a Series

Page 17

of the Fund. The portfolio insurance continues so long as such Trust
retains the Bonds thus insured. Premiums are payable monthly in advance
by the Trustee on behalf of such Trust. As Bonds in the portfolio are
redeemed by their respective issuers or are sold by the Trustee, the
amount of premium will be reduced in respect of those Bonds no longer
owned by and held in the Trust which were insured by insurance obtained
by such Trust. Preinsured Bonds for which insurance has been obtained
from Financial Guaranty and/or AMBAC Indemnity or, beginning with Series
25 and all subsequent Series, other insurers, are not insured by such
Trust. The premium payable for Permanent Insurance will be paid solely
from the proceeds of the sale of such Bond in the event the Trustee
exercises the right to obtain Permanent Insurance on a Bond. The
premiums for such Permanent Insurance with respect to each Bond will
decline over the life of the Bond. An Advantage Trust is not insured;
accordingly, there are no premiums for insurance payable by such Trust.

The following additional charges are or may be incurred by a Trust: all
expenses (including legal and annual auditing expenses) of the Trustee
incurred in connection with its responsibilities under the Indenture,
except in the event of negligence, bad faith or willful misconduct on
its part; the expenses and costs of any action undertaken by the Trustee
to protect the Trust and the rights and interests of the Unit holders;
fees of the Trustee for any extraordinary services performed under the
Indenture; indemnification of the Trustee for any loss, liability or
expense incurred by it without negligence, bad faith or willful
misconduct on its part, arising out of or in connection with its
acceptance or administration of the Trust; indemnification of the
Sponsor for any loss, liability or expense incurred without gross
negligence, bad faith or willful misconduct in acting as Depositor of
the Trust; all taxes and other government charges imposed upon the Bonds
or any part of the Trust (no such taxes or charges are being levied or
made or, to the knowledge of the Sponsor, are contemplated); and
expenditures incurred in contacting Unit holders upon termination of the
Trust. The above expenses and the Trustee's annual fee, when paid or
owing to the Trustee, are secured by a lien on the Trust. In addition,
the Trustee is empowered to sell Bonds of a Trust in order to make funds
available to pay all these amounts if funds are not otherwise available
in the Interest and Principal Accounts of the Trust.

Unless the Sponsor determines that such an audit is not required, the
Indenture requires the accounts of each Trust to be audited on an annual
basis at the expense of the Trust by independent auditors selected by
the Sponsor. So long as the Sponsor is making a secondary market for
Units, the Sponsor shall bear the cost of such annual audits to the
extent such cost exceeds $.50 per Unit. Unit holders of a Trust covered
by an audit may obtain a copy of the audited financial statements from
the Trustee upon request.

                             PUBLIC OFFERING

How is the Public Offering Price Determined?

Although it is not obligated to do so, the Sponsor intends to maintain a
market for the Units and continuously to offer to purchase Units at
prices, subject to change at any time, based upon the aggregate bid
price of the Bonds in the portfolio of each Trust plus the amount of
Purchased Interest of a Trust (if any) and interest accrued to the date
of settlement. All expenses incurred in maintaining a market, other than
the fees of the Evaluator and the costs of the Trustee in transferring
and recording the ownership of Units, will be borne by the Sponsor. If
the supply of Units exceeds demand, or for some other business reason,
the Sponsor may discontinue purchases of Units at such prices. IF A UNIT
HOLDER WISHES TO DISPOSE OF HIS UNITS, HE SHOULD INQUIRE OF THE SPONSOR
AS TO CURRENT MARKET PRICES PRIOR TO MAKING A TENDER FOR REDEMPTION TO
THE TRUSTEE. Prospectuses relating to certain other bond funds indicate
an intention, subject to change, on the part of the respective sponsors
of such funds to repurchase units of those funds on the basis of a price
higher than the bid prices of the securities in the funds. Consequently,
depending upon the prices actually paid, the repurchase price of other
sponsors for units of their funds may be computed on a somewhat more
favorable basis than the repurchase price offered by the Sponsor for
Units of a Trust in secondary market transactions. As in the First Trust
Combined Series, the purchase price per unit of such bond funds will
depend primarily on the value of the securities in the Portfolio of the
applicable Trust.

The Public Offering Price of Units of a Trust will be determined by
adding to the Evaluator's determination of the aggregate bid price of

Page 18

the Bonds in a Trust plus the amount of Purchased Interest of a Trust
(if any) and the appropriate sales charge determined in accordance with
the schedule set forth below, based upon the number of years remaining
to the maturity of each Bond in the portfolio of the Trust, adjusting
the total to reflect the amount of any cash held in or advanced to the
principal account of the Trust and dividing the result by the number of
Units of such trust then outstanding. The minimum sales charge on Units
will be 3% of the Public Offering Price (equivalent to 3.093% of the net
amount invested). For purposes of computation, Bonds will be deemed to
mature on their expressed maturity dates unless: (a) the Bonds have been
called for redemption or funds or securities have been placed in escrow
to redeem them on an earlier call date, in which case such call date
will be deemed to be the date upon which they mature; or (b) such Bonds
are subject to a "mandatory tender," in which case such mandatory tender
will be deemed to be the date upon which they mature. The offering price
of Bonds in the Trust may be expected to be greater than the bid price
of such Bonds by approximately 1-2% of the aggregate principal amount of
such Bonds.

The effect of this method of sales charge computation will be that
different sales charge rates will be applied to each of the various
Bonds in the Trusts based upon the maturities of such bonds, in
accordance with the following schedule:

</TABLE>

There will be no reduction of the sales charges for volume purchases. A
dealer will receive from the Sponsor a dealer concession of 70% of the
total sales charges for Units sold by such dealer and dealers will not
be eligible for additional concessions for Units sold pursuant to the
above schedule.

An investor may aggregate purchases of Units of two or more consecutive
series of a particular State, National, Discount, Intermediate, Long
Intermediate or Short Intermediate Trust for purposes of calculating the
discount for volume purchases listed above. Additionally, with respect
to the employees, officers and directors (including their immediate
family members, defined as spouses, children, grandchildren, parents,
grandparents, mothers-in-law, fathers-in-law, sons-in-law and daughters-
in-law, and trustees, custodians or fiduciaries for the benefit of such
person) of the Sponsor and broker/dealers and their subsidiaries and
vendors providing services to the Sponsor, may purchase Units of the
Trusts during the secondary market at the Public Offering Price less the
concession the Sponsor typically allows broker/dealers.

Any such reduced sales charge shall be the responsibility of the selling
broker/dealer. The reduced sales charge structure will apply on all
purchases of Units in a Trust by the same person on any one day from the
Sponsor or any one broker/dealer and, for purposes of calculating the
applicable sales charge, purchases of Units in the Fund will be
aggregated with concurrent purchases by the same person from the Sponsor
or such broker/dealer of Units in any series of tax-exempt unit
investment trusts sponsored by Nike Securities L.P. Additionally, Units
purchased in the name of the spouse of a purchaser or in the name of a
child of such purchaser will be deemed, for the purpose of calculating
the applicable sales charge, to be additional purchases by the
purchaser. The reduced sales charges will also be applicable to a
trustee or other fiduciary purchasing securities for a single trust
estate or single fiduciary account.

From time to time the Sponsor may implement programs under which
broker/dealers and other selling agents of the Fund may receive nominal
awards from the Sponsor for each of their registered representatives who

Page 19

have sold a minimum number of UIT Units during a specified time period.
In addition, at various times the Sponsor may implement other programs
under which the sales force of broker/dealers and other selling agents
may be eligible to win other nominal awards for certain sales efforts,
or under which the Sponsor will reallow to any such broker/dealer or
other selling agent that sponsors sales contests or recognition programs
conforming to criteria established by the Sponsor, or participates in
sales programs sponsored by the Sponsor, an amount not exceeding the
total applicable sales charges on the sales generated by such person at
the public offering price during such programs. Also, the Sponsor in its
discretion may from time to time pursuant to objective criteria
established by the Sponsor pay fees to qualifying broker/dealers and
other selling agents for certain services or activities which are
primarily intended to result in sales of Units of the Trusts. Such
payments are made by the Sponsor out of its own assets, and not out of
the assets of the Trusts. These programs will not change the price Unit
holders pay for their Units or the amount that the Trusts will receive
from the Units sold.

A comparison of tax-free and equivalent taxable estimated current
returns and estimated long-term returns with the returns on various
taxable investments is one element to consider in making an investment
decision. The Sponsor may from time to time in its advertising and sales
materials compare the then current estimated returns on the Trust and
returns over specified periods on other similar Trusts sponsored by Nike
Securities L.P. with returns on taxable investments such as corporate or
U.S. Government bonds, bank CDs and money market accounts or money
market funds, each of which has investment characteristics that may
differ from those of the Trust. U.S. Government bonds, for example, are
backed by the full faith and credit of the U.S. Government and bank CDs
and money market accounts are insured by an agency of the federal
government. Money market accounts and money market funds provide
stability of principal, but pay interest at rates that vary with the
condition of the short-term debt market. The investment characteristics
of the Trust are described more fully elsewhere in this Prospectus.

The aggregate price of the Bonds in each Trust is determined by the
evaluator (the "Evaluator"), on the basis of bid prices (1) on the basis
of current market prices for the Bonds obtained from dealers or brokers
who customarily deal in bonds comparable to those held by the Trust; (2)
if such prices are not available for any of the Bonds, on the basis of
current market prices for comparable bonds; (3) by determining the value
of the Bonds by appraisal; or (4) by any combination of the above.
Unless Bonds are in default in payment of principal or interest or, in
the Sponsor's opinion, in significant risk of such default, the
Evaluator will not attribute any value to the insurance obtained by an
Insured Trust. On the other hand, the value of insurance obtained by the
issuer of Bonds in a Trust is reflected and included in the market value
of such Bonds.

The Evaluator will consider in its evaluation of Bonds which are in
default in payment of principal or interest or, in the Sponsor's
opinion, in significant risk of such default (the "Defaulted Bonds") and
which are covered by insurance obtained by an Insured Trust, the value
of the insurance guaranteeing interest and principal payments. The value
of the insurance will be equal to the difference between (i) the market
value of Defaulted Bonds assuming the exercise of the right to obtain
Permanent Insurance (less the insurance premium attributable to the
purchase of Permanent Insurance) and (ii) the market value of such
Defaulted Bonds not covered by Permanent Insurance. In addition, the
Evaluator will consider the ability of Financial Guaranty and/or AMBAC
Indemnity to meet its commitments under an Insured Trust's insurance
policy, including the commitments to issue Permanent Insurance. It is
the position of the Sponsor that this is a fair method of valuing the
Bonds and the insurance obtained by an Insured Trust and reflects a
proper valuation method in accordance with the provisions of the
Investment Company Act of 1940.

The Evaluator will be requested to make a determination of the aggregate
price of the Bonds in each Trust, on a bid price basis, as of the close
of trading on the New York Stock Exchange on each day on which it is
open, effective for all sales, purchases or redemptions made subsequent
to the last preceding determination.

Although payment is normally made three business days following the
order for purchase, payment may be made prior thereto. A person will
become owner of the Units on the date of settlement provided payment has
been received. Cash, if any, made available to the Sponsor prior to the
date of settlement for the purchase of Units may be used in the
Sponsor's business and may be deemed to be a benefit to the Sponsor,
subject to the limitations of the Securities Exchange Act of 1934.
Delivery of Certificates representing Units so ordered will be made
three business days following such order or shortly thereafter. See

Page 20

"Rights of Unit Holders-How May Units Be Redeemed?" for information
regarding the ability to redeem Units ordered for purchase.

How are Units Distributed?

Units repurchased in the secondary market (see "Public Offering-Will
There be a Secondary Market?") may be offered by this Prospectus at the
secondary market public offering price determined in the manner
described above.

It is the intention of the Sponsor to qualify Units of the Fund for sale
in a number of states. Sales will be made to dealers and others at
prices which represent a concession or agency commission of 4.0% of the
Public Offering Price per Unit for each State, Discount or National
Trust, 3.0% of the Public Offering Price for an Intermediate or Long
Intermediate Trust, and 2.5% of the Public Offering Price per Unit for a
Short Intermediate Trust. Notwithstanding the foregoing, broker/dealers
or other selling agents who purchase, in the aggregate, $250,000 of the
Trusts on any day will receive a volume concession or agency commission
of $40.00 per Unit. However, resales of Units of a Trust by such
broker/dealers and other selling agents to the public will be made at
the Public Offering Price described in this Prospectus. The Sponsor
reserves the right to change the amount of the concession or agency
commission from time to time. Certain commercial banks are making Units
of the Fund available to their customers on an agency basis. A portion
of the sales charge paid by these customers is retained by or remitted
to the banks in the amounts indicated in the amounts indicated above.
Under the Glass-Steagall Act, banks are prohibited from underwriting
Units; however, the Glass-Steagall Act does permit certain agency
transactions and the banking regulators have not indicated that these
particular agency transactions are not permitted under such Act. In
Texas and in certain other states, any banks making Units available must
be registered as broker/dealers under state law.

From time to time the Sponsor may implement programs under which
Underwriters and dealers of the Fund may receive nominal awards from the
Sponsor for each of their registered representatives who have sold a
minimum number of UIT Units during a specified time period. In addition,
at various times the Sponsor may implement other programs under which
the sales force of an Underwriter or dealer may be eligible to win other
nominal awards for certain sales efforts, or under which the Sponsor
will allow to any such Underwriter or dealer that sponsors sales
contests or recognition programs conforming to criteria established by
the Sponsor, or participates in sales programs sponsored by the Sponsor,
an amount not exceeding the total applicable sales charges on the sales
generated by such person at the public offering price during such
programs. Also, the Sponsor in its discretion may from time to time
pursuant to objective criteria established by the Sponsor pay fees to
qualifying Underwriters or dealers for certain services or activities
which are primarily intended to result in sales of Units of the Trusts.
Such payments are made by the Sponsor out of its own assets, and not out
of the assets of the Trusts. These programs will not change the price
Unit holders pay for their Units or the amount that the Trusts will
receive from the Units sold.

What are the Sponsor's Profits?

The Sponsor and participating dealers will receive a maximum gross sales
commission equal to 5.8% of the Public Offering Price of the Units of
each State Trust (equivalent to 6.157% of the net amount invested), 5.8%
of the Public Offering Price of the Units of a National or Discount
Trust (equivalent to 6.157% of the net amount invested), 4.7% of the
Public Offering Price of the Units of an Intermediate or Long
Intermediate Trust (equivalent to 4.932% of the net amount invested),
and 3.7% of the Public Offering Price of the Units of a Short
Intermediate Trust (equivalent to 3.842% of the net amount invested)
less any reduced sales charge for quantity purchases as described under
"Public Offering-How is the Public Offering Price Determined?"

In maintaining a market for the Units, the Sponsor will also realize
profits or sustain losses in the amount of any difference between the
price at which Units are purchased (based on the bid prices of the Bonds
in each Trust) and the price at which Units are resold (which price is
also based on the bid prices of the Bonds in each Trust and includes a
maximum sales charge of 5.8% for a State Trust, 5.8% for a National or
Discount Trust, 4.7% for an Intermediate or Long Intermediate Trust and
3.7% for a Short Intermediate Trust) or redeemed. The secondary market
public offering price of Units may be greater or less than the cost of
such Units to the Sponsor. 

Page 21


                         RIGHTS OF UNIT HOLDERS

How are Certificates Issued and Transferred?

The Trustee is authorized to treat as the record owner of Units that
person who is registered as such owner on the books of the Trustee.
Ownership of Units is evidenced by registered certificates executed by
the Trustee and the Sponsor. Delivery of certificates representing Units
ordered for purchase is normally made five business days following such
order or shortly thereafter. Certificates are transferable by
presentation and surrender to the Trustee properly endorsed or
accompanied by a written instrument or instruments of transfer.
Certificates to be redeemed must be properly endorsed or accompanied by
a written instrument or instruments of transfer. A Unit holder must sign
exactly as his name appears on the face of the certificate with the
signature guaranteed by a participant in the Securities Transfer Agents
Medallion Program ("STAMP") or such other signature guaranty program in
addition to, or in substitution for, STAMP, as may be accepted by the
Trustee. In certain instances the Trustee may require additional
documents such as, but not limited to, trust instruments, certificates
of death, appointments as executor or administrator or certificates of
corporate authority. Record ownership may occur before settlement.

Certificates will be issued in fully registered form, transferable only
on the books of the Trustee in denominations of one Unit or any multiple
thereof, numbered serially for purposes of identification. Certificates
for Units will bear an appropriate notation on their face indicating
which plan of distribution has been selected in respect thereof. When a
change is made, the existing certificate must be surrendered to the
Trustee and a new certificate issued to reflect the then currently
effective plan of distribution. There is no charge for this service.

Although no such charge is now made or contemplated, a Unit holder may
be required to pay $2.00 to the Trustee per certificate reissued or
transferred for reasons other than to change the plan of distribution,
and to pay any governmental charge that may be imposed in connection
with each such transfer or exchange. For new certificates issued to
replace destroyed, stolen or lost certificates, the Unit holder may be
required to furnish indemnity satisfactory to the Trustee and pay such
expenses as the Trustee may incur. Mutilated certificates must be
surrendered to the Trustee for replacement.

How are Interest and Principal Distributed?

Record Dates for the distribution of interest under the semi-annual
distribution plan are the fifteenth day of June and December with the
Distribution Dates being the last day of the month in which the related
Record Date occurs. It is anticipated that an amount equal to
approximately one-half of the amount of net annual interest income per
Unit will be distributed on or shortly after each Distribution Date to
Unit holders of record on the preceding Record Date. Record Dates for
monthly distributions of interest are the fifteenth day of each month.
The Distribution Dates for distributions of interest under the monthly
plan is the last day of each month in which the related Record Date
occurs. See "Special Trust Information" appearing in each Part I of this
Prospectus.

The plan of distribution selected by a Unit holder will remain in effect
until changed. Unit holders purchasing Units in the secondary market
will initially receive distributions in accordance with the election of
the prior owner. Each year, approximately six weeks prior to the end of
May, the Trustee will furnish each Unit holder a card to be returned to
the Trustee not more than thirty nor less than ten days before the end
of such month. Unit holders desiring to change the plan of distribution
in which they are participating may so indicate on the card and return
same, together with their certificate, to the Trustee. If the card and
certificate are returned to the Trustee, the change will become
effective as of June 16 of that year. If the card and certificate are
not returned to the Trustee, the Unit holder will be deemed to have
elected to continue with the same plan for the following twelve months.

The pro rata share of cash in the Principal Account of each Trust will
be computed as of the fifteenth day of each month, and distributions to
the Unit holders of such Trust as of such Record Date will be made on
the dates specified in Part One. Proceeds from the disposition of any of
the Bonds of such Trust (less any premiums due with respect to Bonds for
which the Trustee has exercised the right to obtain Permanent Insurance)
received after such Record Date and prior to the following Distribution
Date will be held in the Principal Account of such Trust and not
distributed until the next Distribution Date. The Trustee is not

Page 22

required to make a distribution from the Principal Account of a Trust
unless the amount available for distribution shall equal at least $1.00
per Unit.

The Trustee will credit to the Interest Account of each Trust all
interest received by such Trust, including that part of the proceeds
(including insurance proceeds if any, paid to an Insured Trust) of any
disposition of Bonds which represents accrued interest. Other receipts
will be credited to the Principal Account of such Trust. The
distribution to the Unit holders of a Trust as of each Record Date will
be made on the following Distribution Date or shortly thereafter and
shall consist of an amount substantially equal to such portion of the
holder's pro rata share of the estimated annual income of such Trust
after deducting estimated expenses. Except through an advancement of its
own Funds, the Trustee has no cash for distribution to Unit holders
until it receives interest payments on the Bonds in a Trust. The Trustee
shall be reimbursed, without interest, for any such advances from funds
in the Interest Account of such Trust on the ensuing Record Date.
Persons who purchase Units between a Record Date and a Distribution Date
will receive their first distribution on the second Distribution Date
after the purchase, under the applicable plan of distribution. The
Trustee is not required to pay interest on funds held in the Principal
or Interest Account of a Trust (but may itself earn interest thereon and
therefore benefit from the use of such funds).

As of the fifteenth day of each month, the Trustee will deduct from the
Interest Account of each Trust and, to the extent funds are not
sufficient therein, from the Principal Account of each Trust, amounts
necessary to pay the expenses of such Trust. The Trustee also may
withdraw from said accounts such amounts, if any, as it deems necessary
to establish a reserve for any governmental charges payable out of the
Trust. Amounts so withdrawn shall not be considered a part of the
Trust's assets until such time as the Trustee shall return all or any
part of such amounts to the appropriate account. In addition, the
Trustee may withdraw from the Interest Account and the Principal Account
of a Trust such amounts as may be necessary to cover redemption of Units
of such Trust by the Trustee.

How Can Distributions to Unit Holders be Reinvested?

Universal Distribution Option. Unit holders may elect participation in a
Universal Distribution Option which permits a Unit holder to direct the
Trustee to distribute principal and interest payments to any other
investment vehicle of which the Unit holder has an existing account. For
example, at a Unit holder's direction, the Trustee would distribute
automatically on the applicable distribution date interest income or
principal on the participant's Units to, among other investment
vehicles, a Unit holder's checking, bank savings, money market,
insurance, reinvestment or any other account. All such distributions, of
course, are subject to the minimum investment and sales charges, if any,
of the particular investment vehicle to which distributions are
directed. The Trustee will notify the participant of each distribution
pursuant to the Universal Distribution Option. The Trustee will
distribute directly to the Unit holder any distributions which are not
accepted by the specified investment vehicle. A participant may at any
time, by so notifying the Trustee in writing, elect to terminate his
participation in the Universal Distribution Option and receive directly
future distributions on his Units.

Distribution Reinvestment Option. The Sponsor has entered into an
arrangement with Oppenheimer Management Corporation, which permits any
Unit holder of a Trust to elect to have each distribution of interest
income or principal on his Units automatically reinvested in shares of
either the Oppenheimer Intermediate Tax-Exempt Bond Fund (the
"Intermediate Series") or the Oppenheimer Insured Tax-Exempt Bond Fund
(the "Insured Series"). Oppenheimer Management Corporation is the
investment adviser of each Series which are open-end, diversified
management investment companies. The investment objective of the
Intermediate Series is to provide a high level of current interest
income exempt from Federal income tax through the purchase of investment
grade securities. The investment objective of the Insured Series is to
provide as high a level of current interest income exempt from Federal
income tax as is consistent with the assurance of the scheduled receipt
of interest and principal through insurance and the preservation of
capital (the income of either Series may constitute an item of
preference for determining the Federal alternative minimum tax). The
objectives and policies of each Series are presented in more detail in
the prospectus for each Series.

Each person who purchases Units of a Trust may contact the Trustee to
request a prospectus describing each Series and a form by which such
person may elect to become a participant in a Distribution Reinvestment
Option with respect to a Series. Each distribution of interest income or

Page 23

principal on the participant's Units will automatically be applied by
the Trustee to purchase shares (or fractions thereof) of a Series
without a sales charge and with no minimum investment requirements.

The shareholder service agent for each Series will mail to each
participant in the Distribution Reinvestment Option confirmations of all
transactions undertaken for such participant in connection with the
receipt of distributions from The First Trust Combined Series and the
purchase of shares (or fractions thereof) of a Series.

A participant may at any time, by so notifying the Trustee in writing,
elect to terminate his participation in the Distribution Reinvestment
Option and receive future distributions on his Units in cash. There will
be no charge or other penalty for such termination. The Sponsor and
Oppenheimer Management Corporation each have the right to terminate the
Distribution Reinvestment Option, in whole or in part.

It should be remembered that even if distributions are reinvested
through the Universal Distribution Option or the Distribution
Reinvestment Option they are still treated as distributions for income
tax purposes.

What Reports Will Unit Holders Receive?

The Trustee shall furnish Unit holders of each Trust in connection with
each distribution a statement of the amount of interest, if any, and the
amount of other receipts, if any, which are being distributed, expressed
in each case as a dollar amount per Unit. Within a reasonable time after
the last business day of each calendar year, the Trustee will furnish to
each person who at any time during the calendar year was a Unit holder
of a Trust of record, a statement as to (1) the Interest Account:
interest received by such Trust (including amounts representing interest
received upon any disposition of Bonds of such Trust), the amount of
such interest representing insurance proceeds (if applicable),
deductions for payment of applicable taxes and for fees and expenses of
the Trust, redemption of Units and the balance remaining after such
distributions and deductions, expressed both as a total dollar amount
and as a dollar amount representing the pro rata share of each Unit
outstanding on the last business day of such calendar year; (2) the
Principal Account: the dates of disposition of any Bonds of such Trust
and the net proceeds received therefrom (excluding any portion
representing interest and the premium attributable to the exercise of
the right, if applicable, to obtain Permanent Insurance), deduction for
payment of applicable taxes and for fees and expenses of the Trust,
redemptions of Units, and the balance remaining after such distributions
and deductions, expressed both as a total dollar amount and as a dollar
amount representing the pro rata share of each Unit outstanding on the
last business day of such calendar year; (3) the Bonds held and the
number of Units of such Trust outstanding on the last business day of
such calendar year; (4) the Redemption Price per Unit based upon the
last computation thereof made during such calendar year; and (5) the
amounts actually distributed during such calendar year from the Interest
Account and from the Principal Account of such Trust, separately stated,
expressed both as total dollar amounts and as dollar amounts per Unit
outstanding on the Record Date for such distributions.

In order to comply with Federal and state tax reporting requirements,
Unit holders will be furnished, upon request to the Trustee, evaluations
of the Bonds in their Trust furnished to it by the Evaluator.

Each distribution statement will reflect pertinent information in
respect of each plan of distribution so that Unit holders may be
informed regarding the results of the other plan or plans of distribution.

How May Units be Redeemed?

A Unit holder may redeem all or a portion of his Units by tender to the
Trustee at its unit investment trust office in the City of New York of
the certificates representing the Units to be redeemed, duly endorsed or
accompanied by proper instruments of transfer with signature guaranteed
as explained above (or by providing satisfactory indemnity, as in
connection with lost, stolen or destroyed certificates), and payment of
applicable governmental charges, if any. No redemption fee will be
charged. On the third day following such tender, the Unit holder will be
entitled to receive in cash an amount for each Unit equal to the
Redemption Price per Unit next computed after receipt by the Trustee of
such tender of Units. The "date of tender" is deemed to be the date on
which Units are received by the Trustee (if such day is a day on which
the New York Stock Exchange is open for trading), except that as regards
Units received after the close of trading on the New York Stock Exchange
(generally 4:00 p.m. Eastern time or as of any earlier closing time on a
day on which the New York Stock Exchange is scheduled in advance to
close at such earlier time), the date of tender is the next day on which

Page 24

such Exchange is open for trading and such Units will be deemed to have
been tendered to the Trustee on such day for redemption at the
redemption price computed on that day. Units so redeemed shall be
cancelled.

Purchased Interest (if any) and other accrued interest to the settlement
date paid on redemption shall be withdrawn from the Interest Account of
a Trust or, if the balance therein is insufficient, from the Principal
Account of such Trust. All other amounts paid on redemption shall be
withdrawn from the Principal Account of the Trust.

The Redemption Price per Unit will be determined on the basis of the bid
price of the Bonds in a Trust and the amount of Purchased Interest of
the Trust (if any), as of the close of trading on the New York Stock
Exchange on the date any such determination is made. The Redemption Price
per Unit is the pro rata share of each Unit determined by the Trustee on
the basis of (1) the cash on hand in the Trust or moneys in the process
of being collected, (2) the value of the Bonds in such Trust based on
the bid prices of the Bonds, except for those cases in which the value
of the insurance, if applicable, has been added, and (3) Purchased
Interest (if any) and any other interest accrued thereon, less (a)
amounts representing taxes or other governmental charges payable out of
such Trust, (b) the accrued expenses of such Trust, and (c) cash held
for distribution to Unit holders of record as of a date prior to the
evaluation then being made. The Evaluator may determine the value of the
Bonds in a Trust (1) on the basis of current bid prices of the Bonds
obtained from dealers or brokers who customarily deal in bonds
comparable to those held by such Trust, (2) on the basis of bid prices
for bonds comparable to any Bonds for which bid prices are not
available, (3) by determining the value of the Bonds by appraisal, or
(4) by any combination of the above. In determining the Redemption Price
per Unit for an Insured Trust, no value will be attributed to the
portfolio insurance covering the Bonds in such Trust unless such Bonds
are in default in payment of principal or interest or in significant
risk of such default. On the other hand, Bonds insured under a policy
obtained by the Bond issuer, the underwriters, the Sponsor or others are
entitled to the benefits of such insurance at all times and such
benefits are reflected and included in the market value of such Bonds.
See "Why and How are the Insured Trusts Insured?" For a description of
the situations in which the evaluator may value the insurance obtained
by an Insured Trust, see "Public Offering-How is the Public Offering
Price Determined?"

The difference between the bid and offering prices of such Bonds may be
expected to average 1-2% of the principal amount. In the case of
actively traded bonds, the difference may be as little as 1/2 of 1% and,
in the case of inactively traded bonds, such difference usually will not
exceed 3%. Therefore, the price at which Units may be redeemed could be
less than the price paid by the Unit holder and may be less than the par
value of the Securities represented by the Units so redeemed.

The Trustee is empowered to sell underlying Bonds in a Trust in order to
make funds available for redemption. To the extent that Bonds are sold,
the size and diversity of such Trust will be reduced. Such sales may be
required at a time when Bonds would not otherwise be sold and might
result in lower prices than might otherwise be realized.

The right of redemption may be suspended and payment postponed for any
period during which the New York Stock Exchange is closed, other than
for customary weekend and holiday closings, or during which the
Securities and Exchange Commission determines that trading on that
Exchange is restricted or an emergency exists, as a result of which
disposal or evaluation of the Bonds is not reasonably practicable, or
for such other periods as the Securities and Exchange Commission may by
order permit. Under certain extreme circumstances, the Sponsor may apply
to the Securities and Exchange Commission for an order permitting a full
or partial suspension of the right of Unit holders to redeem their Units. 

How May Units be Purchased by the Sponsor?

The Trustee shall notify the Sponsor of any tender of Units for
redemption. If the Sponsor's bid in the secondary market at that time
equals or exceeds the Redemption Price per Unit, which for certain
Trusts includes Purchased Interest, it may purchase such Units by
notifying the Trustee before 12:00 p.m. Eastern time on the next
succeeding business day and by making payment therefor to the Unit
holder not later than the day on which the Units would otherwise have
been redeemed by the Trustee. Units held by the Sponsor may be tendered
to the Trustee for redemption as any other Units. Any profit or loss

Page 25

resulting from the resale or redemption of such Units will belong to the
Sponsor.

How May Bonds be Removed from the Fund?

The Trustee is empowered to sell such of the Bonds in each Trust on a
list furnished by the Sponsor as the Trustee in its sole discretion may
deem necessary to meet redemption requests or pay expenses to the extent
funds are unavailable. As described in the following paragraph and in
certain other unusual circumstances for which it is determined by the
Depositor to be in the best interests of the Unit holders or if there is
no alternative, the Trustee is empowered to sell Bonds in a Trust which
are in default in payment of principal or interest or in significant
risk of such default and for which value has been attributed to the
insurance, if any, obtained by the Trust. See "How May Units be
Redeemed?" The Sponsor is empowered, but not obligated, to direct the
Trustee to dispose of Bonds in a Trust in the event of advanced
refunding. The Sponsor may from time to time act as agent for a Trust
with respect to selling Bonds out of a Trust. From time to time, the
Trustee may retain and pay compensation to the Sponsor subject to the
restrictions under the Investment Company Act of 1940, as amended.

If any default in the payment of principal or interest on any Bond
occurs and no provision for payment is made therefor, either pursuant to
the portfolio insurance, if any, or otherwise, within thirty days, the
Trustee is required to notify the Sponsor thereof. If the Sponsor fails
to instruct the Trustee to sell or to hold such Bond within thirty days
after notification by the Trustee to the Sponsor of such default, the
Trustee may, in its discretion, sell the defaulted Bond and not be
liable for any depreciation or loss thereby incurred.

The Sponsor shall instruct the Trustee to reject any offer made by an
issuer of any of the Bonds to issue new obligations in exchange and
substitution for any Bonds pursuant to a refunding or refinancing plan,
except that the Sponsor may instruct the Trustee to accept such an offer
or to take any other action with respect thereto as the Sponsor may deem
proper if the issuer is in default with respect to such Bonds or in the
written opinion of the Sponsor the issuer will probably default in
respect to such Bonds in the foreseeable future. Any obligations so
received in exchange or substitution will be held by the Trustee subject
to the terms and conditions in the Indenture to the same extent as Bonds
originally deposited thereunder. Within five days after the deposit of
obligations in exchange or substitution for underlying Bonds, the
Trustee is required to give notice thereof to each Unit holder of the
affected Trust, identifying the Bonds eliminated and the Bonds
substituted therefor. Except as stated in this paragraph and under "What
is the First Trust Combined Series?" for Failed Bonds, the acquisition
by a Trust of any securities other than the Bonds initially deposited is
prohibited.

for taking any action or for refraining from taking any action in good
faith pursuant to the Indenture, or for errors in judgment, but shall be
liable only for their own willful misfeasance, bad faith, gross
negligence (ordinary negligence in the case of the Trustee) or reckless
disregard of their obligations and duties. The Trustee shall not be
liable for depreciation or loss incurred by reason of the sale by the

The Trustee shall not be liable for any taxes or other governmental
charges imposed upon or in respect of the Bonds or upon the interest
thereon or upon it as Trustee under the Indenture or upon or in respect
of the Fund which the Trustee may be required to pay under any present
or future law of the United States of America or of any other taxing

customary provisions limiting the liability of the Trustee.

If the Sponsor shall fail to perform any of its duties under the
Indenture or become incapable of acting or become bankrupt or its
affairs are taken over by public authorities, then the Trustee may (a)
appoint a successor Sponsor at rates of compensation deemed by the

effective upon the acceptance of appointment by the successor Evaluator.
If upon resignation of the Evaluator no successor has accepted
appointment within thirty days after notice of resignation, the
Evaluator may apply to a court of competent jurisdiction for the
appointment of a successor.

The Trustee, Sponsor and Unit holders may rely on any evaluation
furnished by the Evaluator and shall have no responsibility for the
accuracy thereof. Determinations by the Evaluator under the Indenture
shall be made in good faith upon the basis of the best information
available to it, provided, however, that the Evaluator shall be under no
liability to the Trustee, Sponsor or Unit holders for errors in
judgment. This provision shall not protect the Evaluator in any case of
willful misfeasance, bad faith, gross negligence or reckless disregard
of its obligations and duties. 

                            OTHER INFORMATION

How May the Indenture be Amended or Terminated?

The Sponsor and the Trustee have the power to amend the Indenture
without the consent of any of the Unit holders when such an amendment is
(1) to cure any ambiguity or to correct or supplement any provision of
the Indenture which may be defective or inconsistent with any other
provision contained therein, or (2) to make such other provisions as
shall not adversely affect the interest of the Unit holders (as

Page 27

determined in good faith by the Sponsor and the Trustee), provided that
the Indenture is not amended to increase the number of Units of any
Trust issuable thereunder or to permit the deposit or acquisition of
securities either in addition to or in substitution for any of the Bonds
of any Trust initially deposited in a Trust, except for the substitution
of certain refunding securities for Bonds or New Bonds for Failed Bonds.
In the event of any amendment, the Trustee is obligated to notify
promptly all Unit holders of the substance of such amendment.

Each Trust may be liquidated at any time by consent of 100% of the Unit
holders of such Trust or by the Trustee when the value of such Trust, as
shown by any evaluation, is less than 20% of the aggregate principal
amount of the Bonds initially deposited in the Trust or by the Trustee
in the event that Units of a Trust not yet sold aggregating more than
60% of the Units of such Trust are tendered for redemption by the
Underwriters, including the Sponsor. If a Trust is liquidated because of
the redemption of unsold Units of the Trust by the Underwriters, the
Sponsor will refund to each purchaser of Units of such Trust the entire
sales charge paid by such purchaser. The Indenture will terminate upon
the redemption, sale or other disposition of the last Bond held
thereunder, but in no event shall it continue beyond the Mandatory
Termination Date as indicated in Part One for each Trust. In the event
of termination, written notice thereof will be sent by the Trustee to
all Unit holders of such Trust. Within a reasonable period after
termination, the Trustee will sell any Bonds remaining in the Trust,
and, after paying all expenses and charges incurred by such Trust, will
distribute to each Unit holder of such Trust (including the Sponsor if
it then holds any Units), upon surrender for cancellation of his
Certificate for Units, his pro rata share of the balances remaining in
the Interest and Principal Accounts of such Trust, all as provided in
the Indenture.

                      DESCRIPTION OF BOND RATINGS*

Standard & Poor's. A brief description of the applicable Standard &
Poor's rating symbols and their meanings follow:

A Standard & Poor's corporate or municipal bond rating is a current
assessment of the creditworthiness of an obligor with respect to a
specific debt obligation. This assessment may take into consideration
obligors such as guarantors, insurers, or lessees.

The bond rating is not a recommendation to purchase, sell or hold a
security, inasmuch as it does not comment as to market price or
suitability for a particular investor.

The ratings are based on current information furnished by the issuer or
obtained by Standard & Poor's from other sources it considers reliable.
Standard & Poor's does not perform an audit in connection with any
rating and may, on occasion, rely on unaudited financial information.
The ratings may be changed, suspended or withdrawn as a result of
changes in, or unavailability of, such information, or for other
circumstances.

The ratings are based, in varying degrees, on the following
considerations:

l.   Likelihood of default-capacity and willingness of the obligor as to
the timely payment of interest and repayment of principal in accordance
with the terms of the obligation; 

ll.  Nature of and provisions of the obligation;

lll. Protection afforded by, and relative position of, the obligation in
the event of bankruptcy, reorganization or other arrangements under the
laws of bankruptcy and other laws affecting creditors' rights.

AAA-Bonds rated AAA have the highest rating assigned by Standard &
Poor's to a debt obligation. Capacity to pay interest and repay
principal is extremely strong.**

AA-Bonds rated AA have a very strong capacity to pay interest and repay
principal and differ from the highest rated issues only in small degree.

A-Bonds rated A have a strong capacity to pay interest and repay
principal although they are somewhat more susceptible to the adverse
effects of changes in circumstances and economic conditions than bonds
in higher rated categories.

BBB-Bonds rated BBB are regarded as having an adequate capacity to pay
interest and repay principal. Whereas they normally exhibit adequate
protection parameters, adverse economic conditions or changing
circumstances are more likely to lead to a weakened capacity to pay
interest and repay principal for bonds in this category than for bonds
in higher rated categories.

Plus (+) or Minus (-): The ratings from "AA" to "BBB" may be modified by
the addition of a plus or minus sign to show relative standing within
the major rating categories. 

Provisional Ratings: The letter "p" indicates that the rating is
provisional. A provisional rating assumes the successful completion of
the project being financed by the bonds being rated and indicates that
payment of debt service requirements is largely or entirely dependent
upon the successful and timely completion of the project. This rating,
however, while addressing credit quality subsequent to completion of the
project, makes no comment on the likelihood of, or the risk of default
upon failure of, such completion. The investor should exercise his/her
own judgment with respect to such likelihood and risk. 

Credit Watch: Credit Watch highlights potential changes in ratings of
bonds and other fixed income securities. It focuses on events and trends
which place companies and government units under special surveillance by
S&P's 180-member analytical staff. These may include mergers, voter
referendums, actions by regulatory authorities, or developments gleaned
from analytical reviews. Unless otherwise noted, a rating decision will
be made within 90 days. Issues appear on Credit Watch where an event,
situation, or deviation from trends occurred and needs to be evaluated
as to its impact on credit ratings. A listing, however, does not mean a
rating change is inevitable. Since S&P continuously monitors all of its
ratings, Credit Watch is not intended to include all issues under
review. Thus, rating changes will occur without issues appearing on
Credit Watch.

________________

*  As published by the rating companies.

** Bonds insured by Financial Guaranty Insurance Company, AMBAC Indemnity
Corporation, Municipal Bond Investors Assurance Corporation, Connie Lee
Insurance Company, Financial Security Assurance and Capital Guaranty
Insurance Company are automatically rated "AAA" by Standard & Poor's.

Page 29


Moody's Investors Service, Inc. A brief description of the applicable
Moody's Investors Service, Inc. rating symbols and their meanings follow:

Aaa-Bonds which are rated Aaa are judged to be of the best quality. They
carry the smallest degree of investment risk and are generally referred
to as "gilt edge." Interest payments are protected by a large or by an
exceptionally stable margin and principal is secure. While the various
protective elements are likely to change, such changes as can be
visualized are most unlikely to impair the fundamentally strong position
of such issues. Their safety is so absolute that with the occasional
exception of oversupply in a few specific instances, characteristically,
their market value is affected solely by money market fluctuations.

Aa-Bonds which are rated Aa are judged to be of high quality by all
standards. Together with the Aaa group they comprise what are generally
known as high grade bonds. They are rated lower than the best bonds
because margins of protection may not be as large as in Aaa securities
or fluctuation of protective elements may be of greater amplitude or
there may be other elements present which make the long term risks
appear somewhat large than in Aaa securities. Their market value is
virtually immune to all but money market influences, with the occasional
exception of oversupply in a few specific instances. 

A-Bonds which are rated A possess many favorable investment attributes
and are to be considered as upper medium grade obligations. Factors
giving security to principal and interest are considered adequate, but
elements may be present which suggest a susceptibility to impairment
sometime in the future. The market value of A-rated bonds may be
influenced to some degree by economic performance during a sustained
period of depressed business conditions, but, during periods of
normalcy, A-rated bonds frequently move in parallel with Aaa and Aa
obligations, with the occasional exception of oversupply in a few
specific instances.

A 1 and Baa 1-Bonds which are rated A 1 and Baa 1 offer the maximum in
security within their quality group, can be bought for possible
upgrading in quality, and additionally, afford the investor an
opportunity to gauge more precisely the relative attractiveness of
offerings in the market place. 

Baa-Bonds which are rated Baa are considered as medium grade
obligations; i.e., they are neither highly protected nor poorly secured.
Interest payments and principal security appear adequate for the present
but certain protective elements may be lacking or may be
characteristically unreliable over any great length of time. Such bonds
lack outstanding investment characteristics and in fact have speculative
characteristics as well. The market value of Baa-rated bonds is more
sensitive to changes in economic circumstances, and aside from
occasional speculative factors applying to some bonds of this class, Baa
market valuations will move in parallel with Aaa, Aa, and A obligations
during periods of economic normalcy, except in instances of oversupply.

Moody's bond rating symbols may contain numerical modifiers of a generic
rating classification. The modifier 1 indicates that the bond ranks at
the high end of its category; the modifier 2 indicates a mid-range
ranking; and the modifier 3 indicates that the issue ranks in the lower
end of its generic rating category.

Con.(---)-Bonds for which the security depends upon the completion of
some act or the fulfillment of some condition are rated conditionally.
These are bonds secured by (a) earnings of projects under construction,
(b) earnings of projects unseasoned in operation experience, (c) rentals
which begin when facilities are completed, or (d) payments to which some
other limiting condition attaches. Parenthetical rating denotes probable
credit stature upon completion of construction or elimination of basis
of condition.

Fitch Investors Service, Inc. A brief description of the applicable
Fitch Investors Service, Inc. rating symbols and their meanings follow:

AAA-Bonds considered to be investment grade and of the highest credit
quality. The obligor has an exceptionally strong ability to pay interest
and repay principal, which is unlikely to be affected by reasonably
foreseeable events.

AA-Bonds considered to be investment grade and of very high credit
quality. The obligor's ability to pay interest and repay principal is
very strong, although not quite as strong as bonds rated AAA. Bonds
rated in the AAA and AA categories are not significantly vulnerable to
foreseeable future developments.

A-Bonds considered to be investment grade and of high credit quality.
The obligor's ability to pay interest and repay principal is considered
to be strong, but may be more vulnerable to adverse changes in economic
conditions and circumstances than bonds with higher ratings.

BBB-Bonds considered to be investment grade and of satisfactory credit
quality. The obligor's ability to pay interest and repay principal is

Page 30

considered to be adequate. Adverse changes in economic conditions and
circumstances, however, are more likely to have adverse impact on these
bonds, and therefore impair timely payment. The likelihood that the
ratings of these bonds will fall below investment grade is higher than
for bonds with higher ratings.

To provide more detailed indications of credit quality, the AA, A and
BBB ratings may be modified by the addition of a plus or minus sign to
show relative standing within these major rating categories.

Federal Tax Status of Unit Holders

At the respective times of issuance of the Bonds, opinions relating to
the validity thereof and to the exclusion of interest thereon from
Federal gross income were rendered by bond counsel to the respective
issuing authorities. Neither the Sponsor, Chapman and Cutler, nor any of
the Special Counsel to the Fund for State tax matters have made any
special review for the Fund of the proceedings relating to the issuance
of the Bonds or of the bases for such opinions. If the interest on a
Bond should be determined to be taxable, the Bond would generally have
to be sold at a substantial discount. In addition, investors could be
required to pay income tax on interest received prior to the date on
which interest is determined to be taxable. Gain realized on the sale or
redemption of the Bonds by the Trustee or of a Unit by a Unit holder is,
however, includable in gross income for Federal income tax purposes and
may be includable in gross income for state tax purposes. (It should be
noted in this connection that such gain does not include any amounts
received in respect of accrued interest or accrued original issue
discount, if any.) If a Bond is acquired with accrued interest, that
portion of the price paid for the accrued interest is added to the tax
basis of the Bond. When this accrued interest is received, it is treated
as a return of capital and reduces the tax basis of the Bond. If a Bond
is purchased for a premium, the amount of the premium is added to the
tax basis of the Bond. Bond premium is amortized over the remaining term
of the Bond, and the tax basis of the Bond is reduced each tax year by
the amount of the premium amortized in that tax year.

For purposes of the following opinions, it is assumed that each asset of
the Trust is debt, the interest on which is excluded from Federal income
tax purposes.  At the time of the closing for each Trust, Chapman and
Cutler, Counsel for the Sponsor, rendered an opinion under then existing
law substantially to the effect that:

(1)  the Trusts are not associations taxable as corporations for Federal
income tax purposes and interest and accrued original issue discount on
Bonds which are excludable from gross income under the Internal Revenue
Code of 1986 (the "Code") will retain its status when distributed to a
Unit holder; however, such interest may be taken into account in
computing the alternative minimum tax, an additional tax on branches of
foreign corporations and the environmental tax (the "Superfund Tax").
See "Certain Tax Matters Applicable to Corporate Unit Holders";

(2)  each Unit holder is considered to be the owner of a pro rata
portion of each asset of the respective Trust under subpart E,
subchapter J of chapter 1 of the Code and will have a taxable event when
the Trust disposes of a Bond, or when the Unit holder redeems or sells
his Units. Unit holders must reduce the tax basis of their Units for
their share of accrued interest received by the respective Trust, if 
any, on Bonds delivered after the date the Unit holders pay for their
Units to

THESE SECURITIES HAVE NOT BEEN APPROVED OR DISAPPROVED BY THE SECURITIES
AND EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION NOR HAS THE
SECURITIES AND EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION
PASSED UPON THE ACCURACY OR ADEQUACY OF THIS PROSPECTUS. ANY
REPRESENTATION TO THE CONTRARY IS A CRIMINAL OFFENSE.

Page 1                                                                   

the extent that such interest accrued on such Bonds during the
period from the Unit holder's settlement date to the date such Bonds are
delivered to the respective Trust and, consequently, such Unit holders
may have an increase in taxable gain or reduction in capital loss upon
the disposition of such Units. Gain or loss upon the sale or redemption
of Units is measured by comparing the proceeds of such sale or
redemption with the adjusted basis of the Units. If the Trustee disposes
of Bonds (whether by sale, payment on maturity, redemption or
otherwise), gain or loss is recognized to the Unit holder. The amount of
any such gain or loss is measured by comparing the Unit holder's pro
rata share of the total proceeds from such disposition with the Unit
holder's basis for his or her fractional interest in the asset disposed
of. In the case of a Unit holder who purchases Units, such basis (before
adjustment for accrual original issue discount and amortized bond
premium, if any) is determined by apportioning the cost of the Units
among each of the Trust assets ratably according to value as of the
valuation date nearest the date of acquisition of the Units. The tax
basis reduction requirements of the Code relating to amortization of
bond premium may, under some circumstances, result in the Unit holder
realizing a taxable gain when his Units are sold or redeemed for an
amount equal to or less than his original cost; and

(3)  any insurance proceeds paid under individual policies obtained by
issuers of Bonds which represent maturing interest on defaulted Bonds
held by the Trustee will be excludable from Federal gross income if, and
to the same extent as, such interest would have been so excludable if
paid in the normal course by the issuer of the defaulted Bonds provided
that, at the time such policies are purchased, the amounts paid for such
policies are reasonable, customary and consistent with the reasonable
expectation that the issuer of the Bonds, rather than the insurer, will
pay debt service on the Bonds. 

Sections 1288 and 1272 of the Code provide a complex set of rules
governing the accrual of original issue discount. These rules provide
that original issue discount accrues either on the basis of a constant
compound interest rate or ratably over the term of the Bond, depending
on the date the Bond was issued. In addition, special rules apply if the
purchase price of a Bond exceeds the original issue price plus the
amount of original issue discount which would have previously accrued
based upon its issue price (its "adjusted issue price") to prior owners.
The application of these rules will also vary depending on the value of
the Bond on the date a Unit holder acquires his Unit, and the price the
Unit holder pays for his Unit. Unit holders should consult their tax
advisers regarding these rules and their application. See "Portfolio"
appearing in Part One for each Trust for information relating to Bonds,
if any, issued at an original issue discount.

The Revenue Reconciliation Act of 1993 (the "Tax Act") subjects tax-
exempt bonds to the market discount rules of the Code effective for
bonds purchased after April 30, 1993. In general, market discount is the
amount (if any) by which the stated redemption price at maturity exceeds
an investor's purchase price (except to the extent that such difference,
if any, is attributable to original issue discount not yet accrued),
subject to statutory de minimis rule. Market discount can arise based on
the price a Trust pays for Bonds or the price a Unit holder pays for his
or her Units. Under the Tax Act, accretion of market discount is taxable
as ordinary income; under prior law the accretion had been treated as
capital gain. Market discount that accretes while a Trust holds a Bond
would be recognized as ordinary income by the Unit holders when
principal payments are received on the Bond, upon sale or at redemption
(including early redemption) or upon the sale or redemption of his or
her Units, unless a Unit holder elects to include market discount in
taxable income as it accrues. The market discount rules are complex and
Unit holders should consult their tax advisers regarding these rules and
their application.

Counsel for the Sponsor has also advised that under Section 265 of the
Code, interest on indebtedness incurred (or continued) to purchase or
carry Units of a Trust is not deductible for Federal income tax
purposes. The Internal Revenue Service has taken the position that such
indebtedness need not be directly traceable to the purchase or carrying
of Units (however, these rules generally do not apply to interest paid
on indebtedness incurred to purchase or improve a personal residence).
Also, under Section 265 of the Code, certain financial institutions that
acquire Units generally would not be able to deduct any of the interest
expense attributable to ownership of Units. Legislative proposals have
been made that would extend the financial institution rules to most
corporations.

In the case of certain of the Bonds in a Trust, the opinions of bond
counsel indicate that interest on such Bonds received by a "substantial
user" of the facilities being financed with the proceeds of these Bonds,
or persons related thereto, for periods while such Bonds are held by
such a user or related person, will not be excludable from Federal gross
income, although interest on such Bonds received by others would be
excludable from Federal gross income. "Substantial user" and "related
person" are defined under the Code and U.S. Treasury Regulations. Any
person who believes he or she may be a substantial user or related
person as so defined should contact his tax adviser.

In general, Section 86 of the Code provides that 50% of Social Security
benefits are includable in gross income to the extent that the sum of
"modified adjusted gross income" plus 50% of the Social Security
benefits received exceeds the "base amount." The base amount is $25,000
for unmarried taxpayers, $32,000 for married taxpayers filing a joint
return and zero for married taxpayers who do not live apart at all times
during the taxable year and who file separate returns. Modified adjusted
gross income is adjusted gross income determined without regard to
certain otherwise allowable deductions and exclusions from gross income
and by including tax-exempt interest. To the extent that Social Security
benefits are includible in gross income, they will be treated as any
other item of gross income.

In addition, under the Tax Act, for taxable years beginning after
December 31 1993, up to 85% of Social Security benefits are includible
in gross income to the extent that the sum of "modified adjusted gross
income" plus 50% of Social Security benefits received exceeds an
"adjusted base amount." The adjusted base amount is $34,000 for
unmarried taxpayers, $44,000 for married taxpayers filing a joint
return, and zero for married taxpayers who do not live apart at all
times during the taxable year and who file separate returns.

Page 2                                                                   


Although tax-exempt interest is included in modified adjusted gross
income solely for the purpose of determining what portion, if any, of
Social Security benefits will be included in gross income, no tax-exempt
interest, including that received from a Trust, will be subject to tax.
A taxpayer whose adjusted gross income already exceeds the base amount
or the adjusted base amount must include 50% or 85%, respectively, of
his Social Security benefits in gross income whether or not he receives
any tax-exempt interest. A taxpayer whose modified adjusted gross income
(after inclusion of tax-exempt interest) does not exceed the base amount
need not include any Social Security benefits in gross income.

In the case of corporations, the alternative tax rate applicable to long-
term capital gains is 35%, effective for long-term capital gains
realized in taxable years beginning on or after January 1, 1993. For
taxpayers other than corporations, net capital gains are subject to a
maximum stated marginal tax rate of 28%. However, it should be noted
that legislative proposals are introduced from time to time that affect
tax rates and could affect relative differences at which ordinary income
and capital gains are taxed. Under the Code, taxpayers must disclose to
the Internal Revenue Service the amount of tax-exempt interest earned
during the year. For purposes of computing the alternative minimum tax
for individuals and corporations and the Superfund Tax for corporations,
interest on certain private activity bonds (which includes most
industrial and housing revenue bonds) issued on or after August 8, 1986
is included as an item of tax preference.

Certain Tax Matters Applicable to Corporate Unit Holders. The
alternative minimum tax and the Superfund Tax for taxable years
beginning after December 31, 1986 depends upon the corporation's
alternative minimum taxable income ("AMTI"), which is the corporation's
taxable income with certain adjustments. One of the adjustment items
used in computing AMTI  and the Superfund Tax of a corporation (other
than an S Corporation, Regulated Investment Company, Real Estate
Investment Trust, or REMIC) is an amount equal to 75% of the excess of
such corporation's "adjusted current earnings" over an amount equal to
its AMTI (before such adjustment item and the alternative tax net
operating loss deduction).  "Adjusted current earnings" includes all tax-
exempt interest, including interest on all of the Bonds in the Trusts.
Under current Code provisions, the Superfund Tax does not apply to tax
years beginning on or after January 1, 1996. Legislative proposals have
been made that would extend the Superfund Tax. Under the provisions of
Section 884 of the Code, a branch profits tax is levied on the
"effectively connected earnings and profits" of certain foreign
corporations which include tax-exempt interest such as interest on the
Bonds in the Trust. Unit holders should consult their tax advisers with
respect to the particular tax consequences to them, including the
corporate alternative minimum tax, the Superfund Tax and the branch
profits tax imposed by Section 884 of the Code.

Ownership of the Units may result in collateral federal income tax
consequences to certain taxpayers, including, without limitation,
corporations, subject to either the environmental tax or the branch
profits tax, financial institutions, certain insurance companies,
certain S corporations, individual recipients of Social Security or
Railroad Retirement benefits and taxpayers who may be deemed to have
incurred (or continued) indebtedness to purchase or carry tax-exempt
obligations. Prospective investors should consult their tax advisers as
to the applicability of any such collateral consequences.

At the time of the closing, Winston & Strawn (previously named Cole &
Deitz), Special Counsel to Series 4-125 of the Fund for New York tax
matters, rendered an opinion under then existing income tax laws of the
State and City of New York, substantially to the effect that each Trust
in Series 4-125 of the Fund is not an association taxable as a
corporation and the income of each Trust in Series 4-125 of the Fund
will be treated as the income of the Unit holder in the same manner as
for Federal income tax purposes (subject to differences in accounting
for discount and premium to the extent the State and/or City of New York
do not conform to current Federal law).

At the time of the closing, Carter, Ledyard & Milburn, Special Counsel
to the Fund for New York tax matters for Series 126 and subsequent
Series of the Fund, rendered an opinion under then existing income tax
laws of the State and City of New York, substantially to the effect that
each Trust will not constitute an association taxable as a corporation
under New York law, and accordingly will not be subject to the New York
State franchise tax or the New York City general corporation tax. Under
the income tax laws of the State and City of New York, the income of
each Trust will be considered the income of the holders of the Units.

LeBoeuf, Lamb, Leiby & MacRae has served as Special Counsel to Series 8-
81, inclusive, of The First Trust of Insured Municipal Bonds, Booth &
Baron has served as Special Counsel to Series 82-147 of The First Trust
of Insured Municipal Bonds and Winston & Strawn (previously named Cole &
Deitz) has served as Special Counsel to Series 148 and subsequent Series
of The First Trust Insured Municipal Bonds for New York tax matters. In
the opinion of such Special Counsels, under the existing income tax laws
of the State and City of New York, each Trust is not an association
taxable as a corporation and the income of each such Trust will be
treated as the income of the Unit holder.

All statements in the Prospectus concerning exemption from Federal,
state or other local taxes are the opinions of Counsel and are to be so
construed.

Certain Considerations

The foregoing information constitutes only a brief summary of some of
the general factors which may impact certain issuers of Bonds and does
not purport to be a complete or exhaustive description of all adverse
conditions to which the issuers of Bonds held by the National Trusts are
subject. Additionally, many factors including national economic, social
and environmental policies and conditions, which are not within the
control of the issuers of the Bonds, could affect or could have an
adverse impact on the financial condition of the issuers. The Sponsor is
unable to predict whether or to what extent such factors or other
factors may affect the issuers of the Bonds, the market value or
marketability of the Bonds or the ability of the respective issuers of
the Bonds acquired by the National Trusts to pay interest on or
principal of the Bonds.

Federal Tax Status of Unit Holders

At the respective times of issuance of the Bonds, opinions relating to
the validity thereof and to the exclusion of interest thereon from
Federal gross income were rendered by bond counsel to the respective
issuing authorities. In addition, with respect to State Trusts, where
applicable, bond counsel to the issuing authorities rendered opinions as
to the exemption of interest on such Bonds, when held by residents of
the state in which the issuers of such Bonds are located, from state
income taxes and certain state or local intangibles and local income
taxes. Neither the Sponsor, Chapman and Cutler, nor any of the Special
Counsel to the Fund for State tax matters have made any special review
for the Fund of the proceedings relating to the issuance of the Bonds or
of the bases for such opinions. If the interest on a Bond should be
determined to be taxable, the Bond would generally have to be sold at a
substantial discount. In addition, investors could be required to pay
income tax on interest received prior to the date on which interest is
determined to be taxable. Gain realized on the sale or redemption of the
Bonds by the Trustee or of a Unit by a Unit holder is includable in
gross income for Federal income tax purposes and may be includable in
gross income for state tax purposes. (Such gain does not include any
amounts received in respect of accrued interest or accrued original
issue discount, if any.) If a Bond is acquired with accrued interest,
that portion of the price paid for the accrued interest is added to the
tax basis of the Bond. When this accrued interest is received, it is
treated as a return of capital and reduces the tax basis of the Bond. If
a Bond is purchased for a premium, the amount of the premium is added to
the tax basis of the Bond. Bond premium is amortized over the remaining
term of the Bond, and the tax basis of the Bond is reduced each tax year
by the amount of the premium amortized in that tax year.

For purposes of the following opinions, it is assumed that each asset of
the Trust is debt, the interest on which is excluded from Federal income
tax purposes. At the time of the closing for each Trust, Chapman and
Cutler, Counsel for the Sponsor, rendered an opinion under then existing
law substantially to the effect that:

(1)  the Trusts are not associations taxable as corporations for Federal
income tax purposes and interest and accrued original issue discount on
Bonds which are excludable from gross income under the Internal Revenue
Code of 1986 (the "Code") will retain its status for Federal income tax
purposes when received by the Trusts and when distributed to a Unit
holder; however, such interest may be taken into account in computing
the alternative minimum tax, an additional tax on branches of foreign
corporations and the environmental tax (the "Superfund Tax"). See

(2)  each Unit holder is considered to be the owner of a pro rata
portion of each asset of the respective Trust under subpart E,
subchapter J of chapter 1 of the Code and will have a taxable event when
the Trust disposes of a Bond, or when the Unit holder redeems or sells
his Units. If the Unit holder disposes of a Unit, he is deemed thereby
to have disposed of his entire pro rata interest in all assets of the
Trust involved including his pro rata portion of all the Bonds
represented by the Unit. Legislative proposals have been made that would
treat certain transactions designed to reduce or eliminate risk of loss
and opportunities for gain as constructive sales for purposes of
recognition of gain (but not loss). Unit holders should consult their
own tax advisors with regard to any such constructive sale rules. Unit
holders must reduce the tax basis of their Units for their share of
accrued interest received by the respective Trust, if any, on Bonds
delivered after the date the Unit holders pay for their Units to the
extent that such interest accrued on such Bonds before the date the
Trust acquired ownership of the Bonds (and the amount of this reduction
may exceed the amount of accrued interest paid to the seller) and,
consequently, such Unit holders may have an increase in taxable gain or
reduction in capital loss upon the disposition of such Units. Gain or
loss upon the sale or redemption of Units is measured by comparing the
proceeds of such sale or redemption with the adjusted basis of the
Units. If the Trustee disposes of Bonds (whether by sale, payment on
maturity, redemption or otherwise), gain or loss is recognized to the
Unit holder (subject to various non-recognition provisions of the Code).
The amount of any such gain or loss is measured by comparing the Unit
holder's pro rata share of the total proceeds from such disposition with
the Unit holder's basis for his or her fractional interest in the asset
disposed of. In the case of a Unit holder who purchases Units, such
basis (before adjustment for accrued original issue discount and
amortized bond premium, if any) is determined by apportioning the cost
of the Units among each of the Trust assets ratably according to value
as of the valuation date nearest the date of acquisition of the Units.
It should be noted that certain legislative proposals have been made
which could affect the calculation of basis for Unit holders holding
securities that are substantially identical to the Bonds. Unit holders
should consult their own tax advisors with regard to the calculation of
basis. The tax basis reduction requirements of the Code relating to
amortization of bond premium may, under some circumstances, result in
the Unit holder realizing a taxable gain when his Units are sold or
redeemed for an amount equal to or less than his original cost; and

(3)  any insurance proceeds paid under individual policies obtained by
issuers of Bonds which represent maturing interest on defaulted Bonds
held by the Trustee will be excludable from Federal gross income if, and
to the same extent as, such interest would have been so excludable if
paid in the normal course by the issuer of the defaulted Bonds provided
that, at the time such policies are purchased, the amounts paid for such
policies are reasonable, customary and consistent with the reasonable
expectation that the issuer of the Bonds, rather than the insurer, will
pay debt service on the Bonds. 

Sections 1288 and 1272 of the Code provide a complex set of rules
governing the accrual of original issue discount. These rules provide
that original issue discount accrues either on the basis of a constant
compound interest rate or ratably over the term of the Bond, depending
on the date the Bond was issued. In addition, special rules apply if the
purchase price of a Bond exceeds the original issue price plus the
amount of original issue discount which would have previously accrued
based upon its issue price (its "adjusted issue price") to prior owners.
If a Bond is acquired with accrued interest, that portion of the price
paid for the accrued interest is added to the tax basis of the Bond.
When this accrued interest is received, it is treated as a return of
capital and reduces the tax basis of the Bond. If a Bond is purchased
for a premium, the amount of the premium is added to the tax basis of
the Bond. Bond premium is amortized over the remaining term of the Bond,
and the tax basis of the Bond is reduced each tax year by the amount of
the premium amortized in that tax year. The application of these rules
will also vary depending on the value of the Bond on the date a Unit
holder acquires his Unit, and the price the Unit holder pays for his
Unit. Unit holders should consult their tax advisers regarding these
rules and their application. See "Portfolio" appearing in Part One for
each Trust for information relating to Bonds, if any, issued at an
original issue discount.

The Revenue Reconciliation Act of 1993 (the "Tax Act") subjects tax-
exempt bonds to the market discount rules of the Code effective for
bonds purchased after April 30, 1993. In general, market discount is the
amount (if any) by which the stated redemption price at maturity exceeds
an investor's purchase price (except to the extent that such difference,
if any, is attributable to original issue discount not yet accrued),
subject to statutory de minimis rule. Market discount can arise based on
the price a Trust pays for Bonds or the price a Unit holder pays for his
or her Units. Under the Tax Act, accretion of market discount is taxable
as ordinary income; under prior law the accretion had been treated as
capital gain. Market discount that accretes while a Trust holds a Bond
would be recognized as ordinary income by the Unit holders when
principal payments are received on the Bond, upon sale or at redemption
(including early redemption) or upon the sale or redemption of his or
her Units, unless a Unit holder elects to include market discount in
taxable income as it accrues. The market discount rules are complex and
Unit holders should consult their tax advisers regarding these rules and
their application.

Counsel for the Sponsor has also advised that under Section 265 of the
Code, interest on indebtedness incurred or continued to purchase or
carry Units of a Trust is not deductible for Federal income tax
purposes. The Internal Revenue Service has taken the position that such
indebtedness need not be directly traceable to the purchase or carrying
of Units (however, these rules generally do not apply to interest paid
on indebtedness incurred to purchase or improve a personal residence).
Also, under Section 265 of the Code, certain financial institutions that
acquire Units generally would not be able to deduct any of the interest
expense attributable to ownership of Units. Legislative proposals have
been made that would extend the financial institution rules to most
corporations. Investors with questions regarding these issues should
consult their tax advisers.

In the case of certain of the Bonds in a Trust, the opinions of bond
counsel indicate that interest on such Bonds received by a "substantial
user" of the facilities being financed with the proceeds of these Bonds,
or persons related thereto, for periods while such Bonds are held by
such a user or related person, will not be excludable from Federal gross
income, although interest on such Bonds received by others would be
excludable from Federal gross income. "Substantial user" and "related
person" are defined under the Code and U.S. Treasury Regulations. Any
person who believes he or she may be a substantial user or related
person as so defined should contact his tax adviser.

In general, Section 86 of the Code provides that 50% of Social Security
benefits are includable in gross income to the extent that the sum of
"modified adjusted gross income" plus 50% of the Social Security
benefits received exceeds the "base amount." The base amount is $25,000
for unmarried taxpayers, $32,000 for married taxpayers filing a joint
return and zero for married taxpayers who do not live apart at all times
during the taxable year and who file separate returns. Modified adjusted
gross income is adjusted gross income determined without regard to
certain otherwise allowable deductions and exclusions from gross income
and by including tax-exempt interest. To the extent that Social Security
benefits are includible in gross income, they will be treated as any
other item of gross income.

In addition, under the Tax Act, for taxable years beginning after
December 31 1993, up to 85% of Social Security benefits are includible
in gross income to the extent that the sum of "modified adjusted gross
income" plus 50% of Social Security benefits received exceeds an
"adjusted base amount." The adjusted base amount is $34,000 for
unmarried taxpayers, $44,000 for married taxpayers filing a joint
return, and zero for married taxpayers who do not live apart at all
times during the taxable year and who file separate returns.

Although tax-exempt interest is included in modified adjusted gross
income solely for the purpose of determining what portion, if any, of
Social Security benefits will be included in gross income, no tax-exempt
interest, including that received from a Trust, will be subject to tax.
A taxpayer whose adjusted gross income already exceeds the base amount
or the adjusted base amount must include 50% or 85%, respectively, of
his Social Security benefits in gross income whether or not he receives
any tax-exempt interest. A taxpayer whose modified adjusted gross income
(after inclusion of tax-exempt interest) does not exceed the base amount
need not include any Social Security benefits in gross income.

For purposes of computing the alternative minimum tax applicable to all
taxpayers (including non-corporate taxpayers) subject to the alternative
minimum tax and the Superfund Tax for corporations, interest on certain
private activity bonds (which includes most industrial and housing
revenue bonds) issued on or after August 8, 1986 is included as an item

Page 3

of tax preference. EXCEPT AS OTHERWISE NOTED IN PART ONE FOR CERTAIN
TRUSTS, THE TRUSTS DO NOT INCLUDE ANY SUCH PRIVATE ACTIVITY BONDS ISSUED
ON OR AFTER THAT DATE.

In the case of corporations, the alternative tax rate applicable to long-
term capital gains is 35%, effective for long-term capital gains
realized in taxable years beginning on or after January 1, 1993. For
taxpayers other than corporations, net capital gains are subject to a
maximum stated marginal tax rate of 28%. However, it should be noted
that legislative proposals are introduced from time to time that affect
tax rates and could affect relative differences at which ordinary income
and capital gains are taxed. Under the Code, taxpayers must disclose to
the Internal Revenue Service the amount of tax-exempt interest earned
during the year. For purposes of computing the alternative minimum tax
for individuals and corporations and the Superfund Tax for corporations,
interest on certain private activity bonds (which includes most
industrial and housing revenue bonds) issued on or after August 8, 1986
is included as an item of tax preference.

Certain Tax Matters Applicable to Corporate Unit Holders. The
alternative minimum tax and the Superfund Tax for taxable years
beginning after December 31, 1986 depends upon the corporation's
alternative minimum taxable income ("AMTI"), which is the corporation's
taxable income with certain adjustments. One of the adjustment items
used in computing AMTI and the Superfund Tax of a corporation (other
than an S Corporation, Regulated Investment Company, Real Estate
Investment Trust, or REMIC) is an amount equal to 75% of the excess of
such corporation's "adjusted current earnings" over an amount equal to
its AMTI (before such adjustment item and the alternative tax net
operating loss deduction). "Adjusted current earnings" includes all tax-
exempt interest, including interest on all of the Bonds in the Trusts.
Under current Code provisions, the Superfund Tax does not apply to tax
years beginning on or after January 1, 1996. Legislative proposals have
been made that would extend the Superfund Tax. Under the provisions of
Section 884 of the Code, a branch profits tax is levied on the
"effectively connected earnings and profits" of certain foreign
corporations which include tax-exempt interest such as interest on the
Bonds in the Trust. Unit holders should consult their tax advisers with
respect to the particular tax consequences to them, including the
corporate alternative minimum tax, the Superfund Tax and the branch
profits tax imposed by Section 884 of the Code.

Ownership of the Units may result in collateral federal income tax
consequences to certain taxpayers, including, without limitation,
corporations, subject to either the environmental tax or the branch
profits tax, financial institutions, certain insurance companies,
certain S corporations, individual recipients of Social Security or
Railroad Retirement benefits and taxpayers who may be deemed to have
incurred (or continued) indebtedness to purchase or carry tax-exempt
obligations. Prospective investors should consult their tax advisers as
to the applicability of any such collateral consequences.

At the time of the closing, Winston & Strawn (previously named Cole &
Deitz), Special Counsel to Series 4-125 of The First Trust Combined
Series for New York tax matters, rendered an opinion under then existing
income tax laws of the State and City of New York, substantially to the
effect that each Trust in Series 4-125 of The First Trust Combined
Series is not an association taxable as a corporation and the income of
each Trust in Series 4-125 of The First Trust Combined Series will be
treated as the income of the Unit holder in the same manner as for
Federal income tax purposes (subject to differences in accounting for
discount and premium to the extent the State and/or City of New York do
not conform to current Federal law).

At the time of the closing, Carter, Ledyard & Milburn, Special Counsel
to The First Trust Combined Series for New York tax matters for Series
126 and subsequent Series of The First Trust Combined Series, rendered
an opinion under then existing income tax laws of the State and City of
New York, substantially to the effect that each Trust will not
constitute an association taxable as a corporation under New York law,
and accordingly will not be subject to the New York State franchise tax
or the New York City general corporation tax. Under the income tax laws
of the State and City of New York, the income of each Trust will be
considered the income of the holders of the Units.

Booth & Baron has served as Special Counsel to Series 1-9 of The First
Trust of Insured Municipal Bonds-Multi-State, inclusive, and Winston &
Strawn (previously named Cole & Deitz) has served as Special Counsel to
Series 10 and 11 of The First Trust of Insured Municipal Bonds-Multi-
State for New York tax matters. In the opinion of such Special Counsels,
under the existing income tax laws of the State and City of New York,

Page 4

each Trust is not an association taxable as a corporation and the income
of each such Trust will be treated as the income of the Unit holder.

All statements in the Prospectus concerning exemption from Federal,
state or other local taxes are the opinions of Counsel and are to be so
construed.

California Tax Status of Unit Holders

At the time of the closing for each California Trust, Special Counsel to
the Fund for California tax matters rendered an opinion under then
existing California income and property tax law applicable to taxpayers
whose income is subject to California income taxation substantially to
the effect that:

Each California Trust is not an association taxable as a corporation and
the income of a California Trust will be treated as the income of the
Unit holders under the income tax laws of California.

Interest on the underlying securities (which may include bonds or other
obligations issued by the governments of Puerto Rico, the Virgin
Islands, Guam or the Northern Mariana Islands) which is exempt from tax
under California personal income tax and property tax laws when received
by a California Trust will, under such laws, retain its status as tax-
exempt interest when distributed to Unit holders. However, interest on
the underlying securities attributed to a Unit holder which is a
corporation subject to the California franchise tax laws may be
includable in its gross income for purposes of determining its
California franchise tax.

Under California income tax law, each Unit holder in a California Trust
will have a taxable event when a California Trust disposes of a security
(whether by sale, exchange, redemption or payment at maturity) or when
the Unit holder redeems or sells Units. Because of the requirement that
tax cost basis be reduced to reflect amortization of bond premium, under
some circumstances a Unit holder may realize taxable gain when Units are
sold or redeemed for an amount equal to, or less than, their original
cost. The total tax cost of each Unit to a Unit holder is allocated
among each of the bond issues held in a California Trust (in accordance
with the proportion of a California Trust comprised by each bond issue)
in order to determine his per unit tax cost for each bond issue; and the
tax cost reduction requirements relating to amortization of bond premium
will apply separately to the per unit cost of each bond issue; and the
tax cost reduction requirements relating to amortization of bond premium
will apply separately to the per unit cost of each bond issue. Unit
holders' bases in their Units, and the bases for their fractional
interest in each California Trust asset, may have to be adjusted for
their pro rata share of accrued interest received, if any, on securities
delivered after the Unit holders' respective settlement dates.

Under the California personal property tax laws, bonds (including the
bonds in a California Trust as well as "regular-way" and "when-issued"
contracts for the purchase of bonds) or any interest therein is exempt
from such tax.

Any proceeds paid under an insurance policy issued to the Trustee of a
Trust with respect to the bonds in a California Trust as well as
"regular-way" and "when-issued" contracts for the purchase of bonds
which represent maturing interest on defaulted obligations held by the
Trustee will be exempt from California personal income tax if, and to
the same extent as, such interest would have been so exempt if paid by
the issuer of the defaulted obligations.

Under Section 17280(b)(2) of the California Revenue and Taxation Code,
interest on indebtedness incurred or continued to purchase or carry
Units of a California Trust is not deductible for the purposes of the
California personal income tax. While there presently is no California
authority interpreting this provision, Section 17280(b)(2) directs the
California Franchise Tax Board to prescribe regulations determining the
proper allocation and apportionment of interest costs for this purpose.
The Franchise Tax Board has not yet proposed or prescribed such
regulations. In interpreting the generally similar Federal provision,
the Internal Revenue Service has taken the position that such
indebtedness need not be directly traceable to the purchase or carrying
of Units (although the Service has not contended that a deduction for
interest on indebtedness incurred to purchase or improve a personal
residence or to purchase goods or services for personal consumption will
be disallowed). In the absence of conflicting regulations or other

Page 5

California authority, the California Franchise Tax Board generally has
interpreted California statutory tax provisions in accord with Internal
Revenue Service interpretations of similar Federal provisions.

FOR INFORMATION WITH RESPECT TO THE FEDERAL INCOME TAX STATUS AND OTHER
TAX MATTERS, SEE "WHAT IS THE FEDERAL TAX STATUS OF UNIT HOLDERS?" 

Certain Considerations 

Economic Factors. Each California Trust is susceptible to political,
economic or regulatory factors affecting issuers of California municipal
obligations (the "California Municipal Obligations"). These include the
possible adverse effects of certain California constitutional
amendments, legislative measures, voter initiatives and other matters
that are described below. The following information provides only a
brief summary of the complex factors affecting the financial situation
in California (the "State") and is derived from sources that are
generally available to investors and are believed to be accurate. No
independent verification has been made of the accuracy or completeness
of any of the following information. It is based in part on information
obtained from various State and local agencies in California or
contained in Official Statements for various California Municipal
Obligations.

There can be no assurance that future statewide or regional economic
difficulties, and the resulting impact on State or local governmental
finances generally, will not adversely affect the market value of
California Municipal Obligations held in the portfolio of a Trust or the
ability of particular obligors to make timely payments of debt service
on (or relating to) those obligations.

Economic Overview. California's economy is the largest among the 50
states and one of the largest in the world. The State's population of
almost 32 million represents 12.3% of the total United States population
and grew by 27% in the 1980s. The June 1996 population projection
forecasts 33.9 million California residents in July 1998. The
diversified economy has major components in agriculture, manufacturing,
high-technology, trade, entertainment, tourism, construction and
services. Total state gross domestic product of $1 trillion in 1997 will
be larger than all but seven nations in the world and California will
become the first state to produce over one trillion dollars worth of
goods and services in a single year.

After suffering through a severe recession, California's economy has
been on a steady recovery since the start of 1994. In 1996, California
had eight consecutive months of record high employment levels.
Employment grew over 330,000 jobs in 1996 or 2.7%, and is expected to
add another 330,000 in 1997. California employment is expanding more
rapidly than the nation as a whole, which saw 2% job gains in 1995. The
strongest growth has been in high technology and export-related
industries, including computer software, business services, electronics,
entertainment and tourism, all of which have offset the recession-
related losses which were heaviest in aerospace and defense-related
industries (which accounted for two-thirds of the job losses), and
finance and insurance. Residential housing construction, with new
permits rising from 94,000 units in 1996 to 110,000 in 1997, is weaker
than in previous recoveries, but has been growing slowly since 1993.

California enjoys a large and diverse labor force. For 1996, the total
civilian labor force was 15,496,000 with 14,372,000 individuals employed
and 1,124,000, or 7.3%, unemployed. In comparison, the unemployment rate
for the United States during the same time was 5.4%. Yet, with several
major industries undergoing restructuring, job losses are occurring in
industries which, in the past, have been a stable source of growth to
California's economy. Energy and telephone companies are deregulating
while banking and insurance are streamlining and consolidating.
Deregulation is expected to make California more competitive by lowering
electric rates by at least 20% over the next five years.

Personal income rose to $815 billion in 1996, a 7.2% increase over 1995,
outpacing gains nationwide. Wages and salaries grew 6.9% during 1996.
This is over 2.5 times the increase in employment. Solid gains in
employment and income are expected to continue for the next several
years with growth above the national average.

Constitutional Limitations on Taxes and Appropriations

Limitation on Taxes. Certain California municipal obligations may be
obligations of issuers which rely in whole or in part, directly or
indirectly, on ad valorem property taxes as a source of revenue. The
taxing powers of California local governments and districts are limited

Page 6

by Article XIIIA of the California Constitution, enacted by the voters
in 1978 and commonly known as "Proposition 13." Briefly, Article XIIIA
limits to 1% of full cash value the rate of ad valorem property taxes on
real property and generally restricts the reassessment of property to
the rate of inflation, not to exceed 2% per year or decline in value,
except upon new construction or change of ownership (subject to a number
of exemptions). Taxing entities may, however, raise ad valorem taxes
above the 1% limit to pay debt service on voter-approved bonded
indebtedness.

Under Article XIIIA, the basic 1% ad valorem tax levy is applied against
the assessed value of property as of the owner's date of acquisition (or
as of March 1, 1975, if acquired earlier), subject to certain
adjustments. This system has resulted in widely varying amounts of tax
on similarly situated properties. Several lawsuits have been filed
challenging the acquisition-based assessment system of Proposition 13
and on June 18, 1992, the U.S. Supreme Court announced a decision
upholding Proposition 13.

Article XIIIA prohibits local governments from raising revenues through
ad valorem property taxes above the 1% limit; it also requires voters of
any governmental unit to give two-thirds approval to levy any "special
tax." Court decisions, however, allowed non-voter approved levy of
"general taxes" which were not dedicated to a specific use. In response
to these decisions, the voters of the State in 1986 adopted an
initiative statute which imposed significant new limits on the ability
of local entities to raise or levy general taxes, except by receiving
majority local voter approval. Significant elements of this initiative,
"Proposition 62," have been overturned in recent court cases. An
initiative proposed to re-enact the provisions of Proposition 62 as a
constitutional amendment was defeated by the voters in November 1990,
but such a proposal may be renewed in the future.

Appropriations Limits. California and its local governments are subject
to an annual "appropriations limit" imposed by Article XIIIB of the
California Constitution, enacted by the voters in 1979 and significantly
amended by Propositions 98 and 111 in 1988 and 1990, respectively.
Article XIIIB prohibits the State or any covered local government from
spending "appropriations subject to limitation" in excess of the
appropriations limit imposed. "Appropriations subject to limitation" are
authorizations to spend "proceeds of taxes," which consist of tax
revenues, and certain other funds, including proceeds from regulatory
licenses, user charges or other fees, to the extent that such proceeds
exceed the cost of providing the product or service, but "proceeds of
taxes" exclude most State subventions to local governments. No limit is
imposed on appropriations of funds which are not "proceeds of taxes,"
such as reasonable user charges or fees, and certain other non-tax
funds, including bond proceeds.

Among the expenditures not included in the Article XIIIB appropriations
limit are (1) the debt service cost of bonds issued or authorized prior
to January 1, 1979 or subsequently authorized by the voters, (2)
appropriations arising from certain emergencies declared by the
Governor, (3) appropriations for certain capital outlay projects, (4)
appropriations by the State of post-1989 increases in gasoline taxes and
vehicle weight fees, and (5) appropriations made in certain cases of
emergency.

The appropriations limit for each year is adjusted annually to reflect
changes in cost of living and population, and any transfers of service
responsibilities between government units. The definitions for such
adjustments were liberalized in 1990 by Proposition 111 to follow more
closely growth in California's economy.

"Excess" revenues are measured over a two-year cycle. With respect to
local governments, excess revenues must be returned by a revision of tax
rates or fee schedules within the two subsequent fiscal years. The
appropriations limit for a local government may be overridden by
referendum under certain conditions for up to four years at a time. With
respect to the State, 50% of any excess revenues is to be distributed to
K-12 school districts and community college districts (collectively, "K-
14 districts") and the other 50% is to be refunded to taxpayers. With
more liberal annual adjustment factors since 1988, and depressed
revenues since 1990 because of the recession, few governments, including
the State, are currently operating near their spending limits, but this
condition may change over time. Local governments may by voter approval
exceed their spending limits for up to four years.

Because of the complex nature of Articles XIIIA and XIIIB of the
California Constitution, the ambiguities and possible inconsistencies in
their terms, and the impossibility of predicting future appropriations
or changes in population and cost of living, and the probability of
continuing legal challenges, it is not currently possible to determine
fully the impact of Article XIIIA or Article XIIIB on California

Page 7

Municipal Obligations or on the ability of California or local
governments to pay debt service on such California Municipal
Obligations. It is not presently possible to predict the outcome of any
pending litigation with respect to the ultimate scope, impact or
constitutionality of either Article XIIIA or Article XIIIB, or the
impact of any such determinations upon State agencies or local
governments, or upon their ability to pay debt service on their
obligations. Future initiatives or legislative changes in laws or the
California Constitution may also affect the ability of the State or
local issuers to repay their obligations.

Obligations of the State of California. Under the California
Constitution, debt service on outstanding general obligation bonds is
the second charge to the General Fund after support of the public school
system and public institutions of higher education. The State had
$17,913,271,000 aggregate principal amount of general obligation bonds
outstanding, and $8,383,864,000 authorized and unissued, as of December
31, 1996. Outstanding lease revenue bonds totaled $5.845 billion as of
June 30, 1996, and are estimated to total $6.398 billion as of June 30,
1997.

General Fund general obligation debt service expenditures for fiscal
year 1995-96 were $1.911 billion, and are estimated at $1.953 billion
and $1.979 billion for fiscal years 1996-97 and 1997-98, respectively.

Recent Financial Results. The principal sources of General Fund revenues
in 1995-96 were the California personal income tax (45% of total
revenues), the sales tax (34%), bank and corporation taxes (12.6%) and
the gross premium tax on insurance (2.6%). California maintains a
Special Fund for Economic Uncertainties (the "Economic Uncertainties
Fund"), derived from General Fund revenues, as a reserve to meet cash
needs of the General Fund.

General. Throughout the 1980s, State spending increased rapidly as the
State population and economy also grew rapidly, including increased
spending for many assistance programs to local governments, which were
constrained by Proposition 13 and other laws. The largest State program
is assistance to local public school districts. In 1988, an initiative
(Proposition 98) was enacted which (subject to suspension by a two-
thirds vote of the Legislature and the Governor) guarantees local school
districts and community college districts a minimum share of State
General Fund revenues (currently about 33%).

Since the start of 1990-91 fiscal year, the State has faced adverse
economic, fiscal, and budget conditions. The economic recession
seriously affected State tax revenues. It also caused increased
expenditures for health and welfare programs. The State has also faced a
structural imbalance in its budget with the largest programs supported
by the General Fund (education, health, welfare and corrections) growing
at rates higher than the growth rates for the principal revenue sources
of the General Fund.

The Budget. On January 10, 1996, the Governor released his proposed
budget for the fiscal year 1996-97. The Governor requested total General
Fund appropriations of about $45.2 billion, based on projected revenues
and transfers of about $45.6 billion, which would leave a budget reserve
in the Economic Uncertainties Fund at June 30, 1997 of about $400
million. The Governor renewed a proposal, which had been rejected by the
Legislature in 1995, for a 15% phased cut in individual and corporate
tax rates over three years (the budget proposal assumed this would be
enacted, reducing revenues in 1996-97 by about $600 million). There was
also a proposal to restructure trial court funding in a way which would
result in a $300 million decrease in General Fund revenues. The Governor
requested legislation to make permanent a moratorium on cost of living
increases for welfare payments, and suspension of a renters tax credit,
which otherwise would go back into effect in the 1996-97 fiscal year.
The Governor further proposed additional cuts in certain health and
welfare programs, and assumed that cuts previously approved by the
Legislature would receive federal approval. Other proposals included an
increase in funding for K-12 schools under Proposition 98, for state
higher education systems (with a second year of no student fee
increases), and for corrections. The Governor's budget projected
external cash flow borrowing of up to $3.2 billion, to mature by June
30, 1997. Revised estimates were published in the Governor's Budget
Summary for fiscal year 1997-98. These estimates and projections are
based upon various assumptions which may be affected by numerous
factors, including future economic conditions in the State and the
nation, and there can be no assurance that the estimates will be achieved.

Preliminary General Fund revenues and transfers for fiscal year 1996-97
are $48.4 billion, a 4.56% increase from the prior year. Expenditures
are estimated at $48.4 billion, a 6.6% increase. The Governor's Budget
Summary for fiscal year 1997-98 projects a positive balance of $197
million in the budget reserve at June 30, 1997. Special Fund revenues
are estimated at $13.54 billion and appropriated Special Fund

Page 8

expenditures at $13.59 billion. As of June 30, 1996, the General Fund
balance was $685.4 million. The estimate for June 30, 1997 is $648
million.

Overall, General Fund revenues and transfers represent about 78% of
total revenues. The remaining 22% are special funds, dedicated to
specific programs. The three largest revenue sources (personal income,
sales, and bank and corporation) account for about 73% of total revenues.

Several important tax changes were enacted in 1996. The bank and
corporation tax was reduced by 5%, and a number of targeted business tax
incentives were put into place.

Proposed 1997-98 Budget. The Governor's proposed budget for fiscal year
1997-98 keeps General Fund spending below revenues. The budget provides
for General Fund revenues and transfers of $50.7 billion, a 4.65%
increase from 1996-97, and expenditures of $50.3 billion, a 4% increase.
The budget provides for a General Fund Reserve for Economic
Uncertainties of $553 million. The balance in the General Fund at the
end of fiscal year 1998 is forecast at $1.004 billion. Special Fund
revenues are estimated to be $14 billion and appropriated Special Fund
expenditures are projected at $14.3 billion.

K-12 education remains the state's top funding priority-nearly 42 cents
of every General Fund dollar is spent on K-12 education. Education,
public safety, and health and welfare expenditures constitute nearly 93%
of all state General Fund expenditures. General Fund expenditures for
1997-98 are proposed in the following amounts and programs: $20.9
billion or 41.6% for K-12 education, $14.6 billion or 28.9% for health
and welfare, $6.5 billion or 12.9% for higher education, and $4.3
billion, or 8.5% for youth and correctional programs. The remaining
expenditures are in areas such as business, transportation, housing and
environmental protection.

The following are principal features of the Governor's 1997-98 budget
proposal:

For fiscal year 1997-98, the Governor's budget proposes a further 10%
reduction in the bank and corporation tax rate phased in over a two-year
period beginning with the 1998 tax year. This would implement the
balance of the Governor's proposal last year for a 15% bank and
corporation tax reduction. In addition, the Governor's Budget proposes
that the State conform with recent federal changes in the allowable
number of Subchapter S shareholders. Combined, these tax reduction
proposals are estimated to reduce taxes by $93 million during 1997-98,
and $336 million during 1998-1999.

The Governor has proposed a $200 million bond to capitalize an
Infrastructure Bank to help finance infrastructure projects related to
business development. The budget also proposes $939,000 to create three
new offices-two in Asia and one in South America-to provide California
companies with representation and assistance in these emerging markets.

Building on the 1996 class-size reduction initiative, the Budget
proposes $304 million to reduce class size in an additional grade, and
funding is provided to meet facilities-related costs of class size
reduction in 1996-97. An additional $57 million is proposed for improved
reading instruction in grades four through eight.

The Budget includes the second year of the Citizens' Option for Public
Safety Program, through which $100 million will be provided to local
governments to increase frontline law enforcement.

The Budget provides a $35 million Infant Health Protection Initiative,
designed to protect children from abuse or neglect from substance-
abusing parents. The budget also provides $15.3 million to increase
immunizations for low-income children.

Bond Rating. State general obligation bonds ratings were reduced in July
1994 to "A1" by Moody's and "A" by Standard & Poor's. Both of these
ratings were reduced from "AAA" levels which the State held until late
1991. There can be no assurance that such ratings will be maintained in
the future. It should be noted that the creditworthiness of obligations
issued by local California issuers may be unrelated to the
creditworthiness of obligations issued by the State of California, and
that there is no obligation on the part of the State to make payment on
such local obligations in the event of default.

Legal Proceedings. The State is involved in certain legal proceedings
(described in the State's recent financial statements) that, if decided
against the State, may require the State to make significant future
expenditures or may substantially impair revenues. In the consolidated
case of Malibu Video Systems, et al. v. Kathleen Brown and Abramovitz,
et al., a stipulated judgment was entered requiring return of $119
million plus interest to specified special funds over a period of up to
five years beginning in fiscal year 1996-97. The lawsuit challenges the
transfer of monies from special fund accounts within the State Treasury
to the State's General Fund pursuant to the Budget Acts of 1991, 1992,
1993 and 1994. Plaintiffs allege that the monetary transfers violated

Page 9

various statutes and provisions of the State Constitution.

Obligations of Other Issuers 

Other Issuers of California Municipal Obligations. There are a number of
state agencies, instrumentalities and political subdivisions of the
State that issue Municipal Obligations, some of which may be conduit
revenue obligations payable from payments from private borrowers. These
entities are subject to various economic risks and uncertainties, and
the credit quality of the securities issued by them may vary
considerably from the credit quality of the obligations backed by the
full faith and credit of the State.

State Assistance. Property tax revenues received by local governments
declined more than 50% following passage of Proposition 13.
Subsequently, the California Legislature enacted measures to provide for
the redistribution of the State's General Fund surplus to local
agencies, the reallocation of certain State revenues to local agencies
and the assumption of certain governmental functions by the State to
assist municipal issuers to raise revenues. Through 1990-91, local
assistance (including public schools) accounted for approximately 75% of
General Fund spending. To reduce State General Fund support for school
districts, the 1992-93 and 1993-94 Budget Acts caused local governments
to transfer $3.9 billion of property tax revenues to school districts,
representing loss of all of the post-Proposition 13 "bailout" aid. The
largest share of these transfers came from counties, and the balance
from cities, special districts and redevelopment agencies. In order to
make up this shortfall, the Legislature proposed and voters approved
dedicating 0.5% of the sales tax to counties and cities for public
safety purposes. In addition, the Legislature has changed laws to
relieve local governments of certain mandates, allowing them to reduce
costs.

To the extent the State should be constrained by its Article XIIIB
appropriations limit, or its obligation to conform to Proposition 98, or
other fiscal considerations, the absolute level, or the rate of growth,
of State assistance to local governments may be further reduced. Any
such reductions in State aid could compound the serious fiscal
constraints already experienced by many local governments, particularly
counties. At least one rural county (Butte) publicly announced that it
might enter bankruptcy proceedings in August 1990, although such plans
were put off after the Governor approved legislation to provide
additional funds for the county. Other counties have also indicated that
their budgetary condition is extremely grave. The Richmond Unified
School District (Contra Costa County) entered bankruptcy proceedings in
May 1991 but the proceedings were dismissed. Los Angeles County, the
largest in the State, has reported severe fiscal problems, leading to a
nominal $1.2 billion deficit in its $11 billion budget for the 1995-96
fiscal year. To balance the budget, the county imposed severe cuts in
services, particularly for healthcare. The Legislature is considering
actions to help alleviate the County's fiscal problems, but none were
completed before August 15, 1995. As a result of its bankruptcy
proceedings (discussed further below) Orange County also implemented
stringent cuts in services and laid off workers.

Assessment Bonds. California Municipal Obligations which are assessment
bonds may be adversely affected by a general decline in real estate
values or a slowdown in real estate sales activity. In many cases, such
bonds are secured by land which is undeveloped at the time of issuance
but anticipated to be developed within a few years after issuance. In
the event of such reduction or slowdown, such development may not occur
or may be delayed, thereby increasing the risk of a default on the
bonds. Because the special assessments or taxes securing these bonds are
not the personal liability of the owners of the property assessed, the
lien on the property is the only security for the bonds. Moreover, in
most cases the issuer of these bonds is not required to make payments on
the bonds in the event of delinquency in the payment of assessments or
taxes, except from amounts, if any, in a reserve fund established for
the bonds.

California Long-Term Lease Obligations. Certain California long-term
lease obligations, though typically payable from the general fund of the
municipality, are subject to "abatement" in the event the facility being
leased is unavailable for beneficial use and occupancy by the
municipality during the term of the lease. Abatement is not a default,
and there may be no remedies available to the holders of the
certificates evidencing the lease obligation in the event abatement
occurs. The most common cases of abatement are failure to complete
construction of the facility before the end of the period during which
lease payments have been capitalized and uninsured casualty losses to
the facility (e.g., due to earthquake). In the event abatement occurs
with respect to a lease obligation, lease payments may be interrupted

Page 10

(if all available insurance proceeds and reserves are exhausted) and the
certificates may not be paid when due.

Several years ago the Richmond Unified School District (the "District")
entered into a lease transaction in which certain existing properties of
the District were sold and leased back in order to obtain funds to cover
operating deficits. Following a fiscal crisis in which the District's
finances were taken over by a State receiver (including a brief period
under bankruptcy court protection), the District failed to make rental
payments on this lease, resulting in a lawsuit by the Trustee for the
Certificate of Participation holders, in which the State was named
defendant (on the grounds that it controlled the District's finances).
One of the defenses raised in answer to this lawsuit was the invalidity
of the District's lease. The trial court has upheld the validity of the
lease and the case has been settled. Any judgment in a future case
against the position asserted by the Trustee in the Richmond case may
have adverse implications for lease transactions of a similar nature by
other California entities.

Other Considerations. The repayment of industrial development securities
secured by real property may be affected by California laws limiting
foreclosure rights of creditors. Securities backed by health care and
hospital revenues may be affected by changes in State regulations
governing cost reimbursements to health care providers under Medi-Cal
(the State's Medicaid program), including risks related to the policy of
awarding exclusive contracts to certain hospitals.

Limitations on ad valorem property taxes may particularly affect "tax
allocation" bonds issued by California redevelopment agencies. Such
bonds are secured solely by the increase in assessed valuation of a
redevelopment project area after the start of redevelopment activity. In
the event that assessed values in the redevelopment project decline
(e.g., because of a major natural disaster such as an earthquake), the
tax increment revenue may be insufficient to make principal and interest
payments on these bonds. Both Moody's and S&P suspended ratings on
California tax allocation bonds after the enactment of Articles XIIIA
and XIIIB, and only resumed such ratings on a selective basis.

Proposition 87, approved by California voters in 1988, requires that all
revenues produced by a tax rate increase go directly to the taxing
entity which increased such tax rate to repay that entity's general
obligation indebtedness. As a result, redevelopment agencies (which,
typically, are the issuers of tax allocation securities) no longer
receive an increase in tax increment when taxes on property in the
project area are increased to repay voter-approved bonded indebtedness.

The effect of these various constitutional and statutory changes upon
the ability of California municipal securities issuers to pay interest
and principal on their obligations remains unclear. Furthermore, other
measures affecting the taxing or spending authority of California or its
political subdivisions may be approved or enacted in the future.
Legislation has been or may be introduced which would modify existing
taxes or other revenue-raising measures or which either would further
limit or, alternatively, would increase the abilities of state and local
governments to impose new taxes or increase existing taxes. It is not
presently possible to predict the extent to which any such legislation
will be enacted. Nor is it presently possible to determine the impact of
any such legislation on California Municipal Obligations in which the
Fund may invest, future allocations of state revenues to local
governments or the abilities of state or local governments to pay the
interest on, or repay the principal of, such California Municipal
Obligations.

Substantially all of California is within an active geologic region
subject to major seismic activity. Northern California, in 1989, and
southern California, in 1994, experienced major earthquakes causing
billions of dollars in damages. The federal government provided more
than $13 billion in aid for both earthquakes, and neither event is
expected to have any long-term negative economic impact. Any California
Municipal Obligation in a California Trust could be affected by an
interruption of revenues because of damaged facilities, or,
consequently, income tax deductions for casualty losses or property tax
assessment reductions. Compensatory financial assistance could be
constrained by the inability of (i) an issuer to have obtained
earthquake insurance coverage at reasonable rates; (ii) an insurer to
perform on its contracts of insurance in the event of widespread losses;
or (iii) the Federal or State government to appropriate sufficient funds
within their respective budget limitations.

On December 7, 1994, Orange County, California (the "County"), together
with its pooled investment fund (the "County Pooled Fund") filed for
protection under Chapter 9 of the federal Bankruptcy Code, after reports
that the County Pooled Fund had suffered significant market losses in
its investments caused a liquidity crisis for the County Pooled Fund and
the County. More than 180 other public entities, most but not all
located in the County, were also depositors in the County Pooled Fund.
As of mid-January 1995, the County estimated that the County Pooled Fund

Page 11

had lost about $1.64 billion, or 23%, of its initial deposits of around
$7.5 billion. The Pooled Fund has been almost completely restructured to
reduce its exposure to changes in County interest rates. Many of the
entities which kept moneys in the County Pooled Fund, including the
County, faced cash flow difficulties because of the bankruptcy filing
and may be required to reduce programs or capital projects. The County
and some of these entities have, and others may in the future, default
in payment of their obligations. Moody's and Standard & Poor's have
suspended, reduced to below investment grade levels, or placed on
"Credit Watch" various securities of the County and the entities
participating in the Pooled Fund.

On May 2, 1995, the Bankruptcy Court approved a settlement agreement
covering claims of the other participating entities against the County
and the Pooled Fund. Most participants have received in cash 80% (90%
for school districts) of their Pooled Fund investment; the balance is to
be paid in the future. The County succeeded in deferring, by consent,
until June 30, 1996, the repayment of $800 million of short-term
obligations due in July and August, 1995; these notes are, however,
considered to be in default by Moody's and S&P. On June 27, 1995, County
voters turned down a proposal for a temporary 0.5% increase in the local
sales tax, making the County's fiscal recovery much harder.

The portfolio of the First Trust of Insured Municipal Bonds-Multi-State:
California Trust, Series 12 contains Certificates of Participation (1992
Water System Improvement Project and Refunding) (the "Certificates of
Participation") issued by the City of Santa Barbara for which water
revenues are dedicated for payment of principal and interest. See
"Portfolio" in Part One. The City of Santa Barbara invested in the
County Pooled Fund and may be adversely affected by the difficulties
described above. The Sponsor is not currently able to predict whether
such Certificates of Participation will be negatively impacted by the
circumstances faced by the City of Santa Barbara as a result of the
losses of the County Pooled Fund. However, the Certificates of
Participation are insured by AMBAC Indemnity Corporation for the payment
of principal and interest. See "Why and How are the Insured Trusts
Insured?" in Part Two of the Prospectus. Other Series of the California
Trust may have Bonds affected by bankruptcy filing. The Sponsor,
however, is unable to predict the ultimate impact of the circumstances
described above on other issuers located in California.

The State of California has no obligation with respect to any
obligations or securities of the County or any of the other
participating entities, although under existing legal precedents, the
State may be obligated to ensure that school districts have sufficient
funds to operate. All school districts were able to meet their
obligations in the 1994-95 fiscal year.

The foregoing information constitutes only a brief summary of some of
the general factors which may impact certain issuers of Bonds and does
not purport to be a complete or exhaustive description of all adverse
conditions to which the issuers of Bonds held by the California Trusts
are subject. Additionally, many factors including national economic,
social and environmental policies and conditions, which are not within
the control of the issuers of the Bonds, could affect or could have an
adverse impact on the financial condition of the issuers. The Sponsor is
unable to predict whether or to what extent such factors or other
factors may affect the issuers of the Bonds, the market value or
marketability of the Bonds or the ability of the respective issuers of
the Bonds acquired by the California Trusts to pay interest on or
principal of the Bonds.

Federal Tax Status of Unit Holders

At the respective times of issuance of the Bonds, opinions relating to
the validity thereof and to the exclusion of interest thereon from
Federal gross income were rendered by bond counsel to the respective
issuing authorities. Neither the Sponsor, Chapman and Cutler, nor any of
the Special Counsel to the Fund for State tax matters have made any
special review for the Fund of the proceedings relating to the issuance
of the Bonds or of the bases for such opinions. If the interest on a
Bond should be determined to be taxable, the Bond would generally have
to be sold at a substantial discount. In addition, investors could be
required to pay income tax on interest received prior to the date on
which interest is determined to be taxable. Gain realized on the sale or
redemption of the Bonds by the Trustee or of a Unit by a Unit holder is,
however, includable in gross income for Federal income tax purposes and
may be includable in gross income for state tax purposes. (It should be
noted in this connection that such gain does not include any amounts
received in respect of accrued interest or accrued original issue
discount, if any.) If a Bond is acquired with accrued interest, that
portion of the price paid for the accrued interest is added to the tax
basis of the Bond. When this accrued interest is received, it is treated
as a return of capital and reduces the tax basis of the Bond. If a Bond
is purchased for a premium, the amount of the premium is added to the
tax basis of the Bond. Bond premium is amortized over the remaining term
of the Bond, and the tax basis of the Bond is reduced each tax year by
the amount of the premium amortized in that tax year.

For purposes of the following opinions, it is assumed that each asset of
the Trust is debt, the interest on which is excluded from Federal income
tax purposes. At the time of the closing for each Trust, Chapman and
Cutler, Counsel for the Sponsor, rendered an opinion under then existing
law substantially to the effect that:

(1)  the Trusts are not associations taxable as corporations for Federal
income tax purposes and interest and accrued original issue discount on
Bonds which are excludable from gross income under the Internal Revenue
Code of 1986 (the "Code") will retain its status when distributed to a
Unit holder; however, such interest may be taken into account in
computing the alternative minimum tax, an additional tax on branches of
foreign corporations and the environmental tax (the "Superfund Tax").
See "Certain Tax Matters Applicable to Corporate Unit Holders";

(2)  each Unit holder is considered to be the owner of a pro rata
portion of each asset of the respective Trust under subpart E,
subchapter J of chapter 1 of the Code and will have a taxable event

ALL PARTS OF THE PROSPECTUS SHOULD BE RETAINED FOR FUTURE REFERENCE.

THESE SECURITIES HAVE NOT BEEN APPROVED OR DISAPPROVED BY THE SECURITIES
AND EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION NOR HAS THE
SECURITIES AND EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION
PASSED UPON THE ACCURACY OR ADEQUACY OF THIS PROSPECTUS. ANY
REPRESENTATION TO THE CONTRARY IS A CRIMINAL OFFENSE.

Page 1                                                                   

when the Trust disposes of a Bond, or when the Unit holder redeems
or sells his Units. Unit holders must reduce the tax basis of their
Units for their share of accrued interest received by the respective
Trust, if  any, on Bonds delivered after the date the Unit holders pay
for their Units to the extent that such interest accrued on such Bonds
during the period from the Unit holder's settlement date to the date
such Bonds are delivered to the respective Trust and, consequently, such
Unit holders may have an increase in taxable gain or reduction in
capital loss upon the disposition of such Units. Gain or loss upon the
sale or redemption of Units is measured by comparing the proceeds of
such sale or redemption with the adjusted basis of the Units. If the
Trustee disposes of Bonds (whether by sale, payment on maturity,
redemption or otherwise), gain or loss is recognized to the Unit holder.
The amount of any such gain or loss is measured by comparing the Unit
holder's pro rata share of the total proceeds from such disposition with
the Unit holder's basis for his or her fractional interest in the asset
disposed of. In the case of a Unit holder who purchases Units, such
basis (before adjustment for accrual original issue discount and
amortized bond premium, if any) is determined by apportioning the cost
of the Units among each of the Trust assets ratably according to value
as of the valuation date nearest the date of acquisition of the Units.
The tax basis reduction requirements of the Code relating to
amortization of bond premium may, under some circumstances, result in
the Unit holder realizing a taxable gain when his Units are sold or
redeemed for an amount equal to or less than his original cost; and

(3)  any insurance proceeds paid under individual policies obtained by
issuers of Bonds which represent maturing interest on defaulted Bonds
held by the Trustee will be excludable from Federal gross income if, and
to the same extent as, such interest would have been so excludable if
paid in the normal course by the issuer of the defaulted Bonds provided
that, at the time such policies are purchased, the amounts paid for such
policies are reasonable, customary and consistent with the reasonable
expectation that the issuer of the Bonds, rather than the insurer, will
pay debt service on the Bonds. 

Sections 1288 and 1272 of the Code provide a complex set of rules
governing the accrual of original issue discount. These rules provide
that original issue discount accrues either on the basis of a constant
compound interest rate or ratably over the term of the Bond, depending
on the date the Bond was issued. In addition, special rules apply if the
purchase price of a Bond exceeds the original issue price plus the
amount of original issue discount which would have previously accrued
based upon its issue price (its "adjusted issue price") to prior owners.
The application of these rules will also vary depending on the value of
the Bond on the date a Unit holder acquires his Unit, and the price the
Unit holder pays for his Unit. Unit holders should consult their tax
advisers regarding these rules and their application. See "Portfolio"
appearing in Part One for each Trust for information relating to Bonds,
if any, issued at an original issue discount.

The Revenue Reconciliation Act of 1993 (the "Tax Act") subjects tax-
exempt bonds to the market discount rules of the Code effective for
bonds purchased after April 30, 1993. In general, market discount is the
amount (if any) by which the stated redemption price at maturity exceeds
an investor's purchase price (except to the extent that such difference,
if any, is attributable to original issue discount not yet accrued),
subject to statutory de minimis rule. Market discount can arise based on
the price a Trust pays for Bonds or the price a Unit holder pays for his
or her Units. Under the Tax Act, accretion of market discount is taxable
as ordinary income; under prior law the accretion had been treated as
capital gain. Market discount that accretes while a Trust holds a Bond
would be recognized as ordinary income by the Unit holders when
principal payments are received on the Bond, upon sale or at redemption
(including early redemption) or upon the sale or redemption of his or
her Units, unless a Unit holder elects to include market discount in
taxable income as it accrues. The market discount rules are complex and
Unit holders should consult their tax advisers regarding these rules and
their application.

Counsel for the Sponsor has also advised that under Section 265 of the
Code, interest on indebtedness incurred (or continued) to purchase or
carry Units of a Trust is not deductible for Federal income tax
purposes. The Internal Revenue Service has taken the position that such
indebtedness need not be directly traceable to the purchase or carrying
of Units (however, these rules generally do not apply to interest paid
on indebtedness incurred to purchase or improve a personal residence).
Also, under Section 265 of the Code, certain financial institutions that

Page 2                                                                   

acquire Units generally would not be able to deduct any of the interest
expense attributable to ownership of Units. Legislative proposals have
been made that would extend the financial institution rules to most
corporations.

In the case of certain of the Bonds in a Trust, the opinions of bond
counsel indicate that interest on such Bonds received by a "substantial
user" of the facilities being financed with the proceeds of these Bonds,
or persons related thereto, for periods while such Bonds are held by
such a user or related person, will not be excludable from Federal gross
income, although interest on such Bonds received by others would be
excludable from Federal gross income. "Substantial user" and "related
person" are defined under the Code and U.S. Treasury Regulations. Any
person who believes he or she may be a substantial user or related
person as so defined should contact his tax adviser.

In general, Section 86 of the Code provides that 50% of Social Security
benefits are includable in gross income to the extent that the sum of
"modified adjusted gross income" plus 50% of the Social Security
benefits received exceeds the "base amount." The base amount is $25,000
for unmarried taxpayers, $32,000 for married taxpayers filing a joint
return and zero for married taxpayers who do not live apart at all times
during the taxable year and who file separate returns. Modified adjusted
gross income is adjusted gross income determined without regard to
certain otherwise allowable deductions and exclusions from gross income
and by including tax-exempt interest. To the extent that Social Security
benefits are includable in gross income, they will be treated as any
other item of gross income.

In addition, under the Tax Act, for taxable years beginning after
December 31 1993, up to 85% of Social Security benefits are includable
in gross income to the extent that the sum of "modified adjusted gross
income" plus 50% of Social Security benefits received exceeds an
"adjusted base amount." The adjusted base amount is $34,000 for
unmarried taxpayers, $44,000 for married taxpayers filing a joint
return, and zero for married taxpayers who do not live apart at all
times during the taxable year and who file separate returns.

Although tax-exempt interest is included in modified adjusted gross
income solely for the purpose of determining what portion, if any, of
Social Security benefits will be included in gross income, no tax-exempt
interest, including that received from a Trust, will be subject to tax.
A taxpayer whose adjusted gross income already exceeds the base amount
or the adjusted base amount must include 50% or 85%, respectively, of
his Social Security benefits in gross income whether or not he receives
any tax-exempt interest. A taxpayer whose modified adjusted gross income
(after inclusion of tax-exempt interest) does not exceed the base amount
need not include any Social Security benefits in gross income.

In the case of corporations, the alternative tax rate applicable to long-
term capital gains is 35%, effective for long-term capital gains
realized in taxable years beginning on or after January 1, 1993. For
taxpayers other than corporations, net capital gains are subject to a
maximum stated marginal tax rate of 28%. However, it should be noted
that legislative proposals are introduced from time to time that affect
tax rates and could affect relative differences at which ordinary income
and capital gains are taxed. Under the Code, taxpayers must disclose to
the Internal Revenue Service the amount of tax-exempt interest earned
during the year. For purposes of computing the alternative minimum tax
for individuals and corporations and the Superfund Tax for corporations,
interest on certain private activity bonds (which includes most
industrial and housing revenue bonds) issued on or after August 8, 1986
is included as an item of tax preference.

Certain Tax Matters Applicable to Corporate Unit Holders. The
alternative minimum tax and the Superfund Tax for taxable years
beginning after December 31, 1986 depends upon the corporation's
alternative minimum taxable income ("AMTI"), which is the corporation's
taxable income with certain adjustments. One of the adjustment items
used in computing AMTI  and the Superfund Tax of a corporation (other
than an S Corporation, Regulated Investment Company, Real Estate
Investment Trust, or REMIC) is an amount equal to 75% of the excess of
such corporation's "adjusted current earnings" over an amount equal to
its AMTI (before such adjustment item and the alternative tax net
operating loss deduction).  "Adjusted current earnings" includes all tax-
exempt interest, including interest on all of the Bonds in the Trusts.
Under current Code provisions, the Superfund Tax does not apply to tax
years beginning on or after January 1, 1996. Legislative proposals have
been made that would extend the Superfund Tax. Under the provisions of
Section 884 of the Code, a branch profits tax is levied on the
"effectively connected earnings and profits" of certain foreign
corporations which include tax-exempt interest such as interest on the
Bonds in the Trust. Unit holders should consult their tax advisers with

Page 3                                                                   

respect to the particular tax consequences to them, including the
corporate alternative minimum tax, the Superfund Tax and the branch
profits tax imposed by Section 884 of the Code. 

Ownership of the Units may result in collateral federal income tax
consequences to certain taxpayers, including, without limitation,
corporations, subject to either the environmental tax or the branch
profits tax, financial institutions, certain insurance companies,
certain S corporations, individual recipients of Social Security or
Railroad Retirement benefits and taxpayers who may be deemed to have
incurred (or continued) indebtedness to purchase or carry tax-exempt
obligations. Prospective investors should consult their tax advisers as
to the applicability of any such collateral consequences.

At the time of the closing, Winston & Strawn (previously named Cole &
Deitz), Special Counsel to Series 4-125 of the Fund for New York tax
matters, rendered an opinion under then existing income tax laws of the
State and City of New York, substantially to the effect that each Trust
in Series 4-125 of the Fund is not an association taxable as a
corporation and the income of each Trust in Series 4-125 of the Fund
will be treated as the income of the Unit holder in the same manner as
for Federal income tax purposes (subject to differences in accounting
for discount and premium to the extent the State and/or City of New York
do not conform to current Federal law).

At the time of the closing, Carter, Ledyard & Milburn, Special Counsel
to the Fund for New York tax matters for Series 126 and subsequent
Series of the Fund, rendered an opinion under then existing income tax
laws of the State and City of New York, substantially to the effect that
each Trust will not constitute an association taxable as a corporation
under New York law, and accordingly will not be subject to the New York
State franchise tax or the New York City general corporation tax. Under
the income tax laws of the State and City of New York, the income of
each Trust will be considered the income of the holders of the Units.

All statements in the Prospectus concerning exemption from Federal,
state or other local taxes are the opinions of Counsel and are to be so
construed.

New York Tax Status of Unit Holders

At the time of the closing for Series 1, 2 and 3 of The First Trust
Combined Series; Series 1-9 of The First Trust of Insured Municipal
Bonds-Multi-State; and all Series of the New York Trust included in a
Series of The First Trust of Insured Municipal Bonds-New York; Booth &
Baron, Special Counsel to these Series for New York tax matters,
rendered an opinion under then existing New York income tax law
applicable to taxpayers whose income is subject to New York income
taxation substantially to the effect that:

Each New York Trust is not an association taxable as a corporation, and
the income of a New York Trust will be treated as the income of the Unit
holders under the existing income tax laws of the State and City of New
York, in the same manner as for Federal income tax purposes (subject to
differences in accounting for discount and premium to the extent the
State and/or City of New York do not conform to current Federal law).

Individuals holding Units of a New York Insured Trust who reside in New
York State or City will not be subject to State and City personal income
tax on interest income which is excludable from Federal gross income
under section 103 of the Internal Revenue Code of 1986 and derived from
any obligation of New York State or a political subdivision thereof, or
of the Government of Puerto Rico or a political subdivision thereof, or
of the Government of Guam or by its authority, although they will be
subject to New York State and City personal income tax with respect to
any gains realized when such obligations are sold, redeemed or paid at
maturity or when any such Units are sold or redeemed; and

For individuals holding Units of a New York Trust who reside in New York
State or City, any proceeds paid to the Trustee under the applicable
insurance policies which represent maturing interest on defaulted
obligations held by the Trustee will not be subject to New York State or
City personal income tax if, and to the same extent as, such interest
would not have been subject to New York State or City personal income
tax if paid by the issuer of the defaulted obligations.

Certain Considerations

Each New York Trust includes obligations issued by New York State (the
"State"), by its various public bodies (the "Agencies"), and/or by other
entities located within the State, including the City of New York (the
"City").

Some of the more significant events and conditions relating to the
financial situation in New York are summarized below. This section
provides only a brief summary of the complex factors affecting the
financial situation in New York and is derived from sources that are
generally available to investors and is believed to be accurate. It is
based in part on Official Statements and prospectuses issued by, and on
other information reported by the State, the City, and the Agencies in
connection with the issuance of their respective securities.

There can be no assurance that current or future statewide or regional
economic difficulties, and the resulting impact on State or local
government finances generally, will not adversely affect the market
value of New York Municipal Obligations held in the portfolios of the
Trusts or the ability of particular obligors to make timely payments of
debt service on (or relating to) those obligations.

(1) The State: The State has historically been one of the wealthiest
states in the nation. For decades, however, the State economy has grown
more slowly than that of the nation as a whole, gradually eroding the
State's relative economic affluence. Statewide, urban centers have
experienced significant changes involving migration of the more affluent
to the suburbs and an influx of generally less affluent residents.
Regionally, the older Northeast cities have suffered because of the
relative success that the South and the West have had in attracting
people and business. The City has also had to face greater competition
as other major cities have developed financial and business capabilities
which make them less dependent on the specialized services traditionally
available almost exclusively in the City.

The State has for many years had a very high state and local tax burden
relative to other states. The burden of State and local taxation, in
combination with the many other causes of regional economic dislocation,
has contributed to the decisions of some businesses and individuals to
relocate outside, or not locate within, the State. However, the State's
1995-96 budget reflected significant actions to reduce the burden of
State taxation, including adoption of a 3-year, 20% reduction in the
State's personal income tax. During 1996-97, New York led the nation in
tax cuts, at 54.1%, bringing the total value of tax reductions in effect
for the 1997 year to over $6 billion. When measured as a percentage of
personal income, state-imposed taxes in New York should be below the
national median in 1997. The budget for fiscal year 1997-98 reflects an
additional $170 million in tax reductions.

Slowdown of Regional Economy. A national recession commenced in mid-
1990. The downturn continued throughout the State's 1990-91 fiscal year
and was followed by a period of weak economic growth during the 1991
calendar year. Economic recovery started considerably later in the State
than in the nation as a whole due in part to the significant
retrenchment in the banking and financial services industries,
downsizing by several major corporations, cutbacks in defense spending,
and an oversupply of office buildings. In the last few years, New York
has shown signs of economic resurgence. Since 1994, New York has jumped
from 15th to 6th in terms of total private sector employment growth
compared to other states, gaining 140,000 private sector jobs since
December 1994, despite banking layoffs and closure of a major automotive
plant. Overall employment growth was close to 0.7%, almost 60,000 jobs,
for 1996. National employment growth in 1996 was 2.0%. The New York
economy in 1997 is expected to grow at about the same rate as in 1996.
Many uncertainties exist in forecasts of both the national and State
economies and there can be no assurance that the State economy will
perform at a level sufficient to meet the State's projections of
receipts and disbursements.

1997-98 Fiscal Year. The Governor presented the recommended Executive
Budget for the 1997-98 fiscal year in January, 1997. The 1997-98 budget
gap is smaller than the previous two fiscal year projections. The
baseline budget forecast produced an estimated $2.3 billion budget
imbalance, before reflecting any actions taken by the Governor to
produce a balanced 1997-98 Financial Plan. Projections of baseline
revenue growth showed a decline of almost $2 billion, reflecting the
loss of non-recurring receipts used in 1996-97 and implementation of
previously enacted tax reduction programs.

The 1996-97 surplus of $943 million reduced the 1997-98 budget gap to
$1.3 billion. Proposals included in the Executive Budget for 1997-98
close this remaining gap, reducing State spending for the third straight

Page 5                                                                   

year, and permitting three new tax reduction proposals: the $1.7
billion, multi-year property tax reduction portion of STAR (School Tax
Relief initiative); a three-year phased reduction in the estate and gift
tax; and a $50 million reserve for additional targeted job-creating tax
reductions. The budget also makes a significant investment in school aid-
a proposed increase of $302 million on a school year basis as the first
step toward implementing the $1.7 billion school aid portion of STAR.

The 1997-98 Financial Plan includes approximately $66 million in non-
recurring resources, or only 0.2% of the General Fund budget-the lowest
level in more than a decade. As compared to 1996-97, non-recurring
resources are a much smaller component of the budget: down over $1
billion from last year's adopted budget. The loss of these resources in
future years is more than offset by recommendations which provide higher
annualized savings in 1998-99 and beyond.

Assuming these gap-closing actions, the Financial Plan projects receipts
of $32.9 billion and spending of $32.8 billion in fiscal year 1997-98,
with a required deposit of $15 million to the Tax Stabilization Reserve
Fund (TSRF) and an increase of $24 million in the Contingency Reserve
Fund (CRF). The closing fund balance in the General Fund is projected to
be $332 million, the largest amount ever on deposit.

1996-97 Fiscal Year. The 1996-97 State Financial Plan projected General
Fund receipts and transfers from other funds at $32.966 billion and
disbursements and transfers to other funds at $32.895 billion. The 1996-
97 General Fund Financial Plan continues to be balanced, with a
projected surplus of $1.3 billion. This will be the second consecutive
material budget surplus generated by the Governor's administration. Of
this amount, $250 million is being used to accelerate the last portion
of the Governor's personal income tax cut through changes to the 1997
withholding tables. This raises taxpayers' current take-home pay rather
than issuing larger refunds in 1998. Of the remainder, $943 million is
being used to help close the projected 1997-98 budget gap, and $65
million is being deposited into the Tax Stabilization Reserve Fund (the
State's "rainy day" fund) as provided by the Constitution. This is the
maximum amount that can be deposited, and increases the size of that
fund to $332 million by the end of 1997-98, the highest balance ever
achieved.

The surplus results primarily from growth in projected receipts. As
compared to the enacted budget, revenues increased by more than $1
billion, while disbursements fell by $228 million. These changes from
original Financial Plan projections reflect actual results through
December 1996 as well as modified economic and caseload projections for
the balance of the fiscal year.

The General Fund closing balance is expected to be $358 million at the
end of 1996-97. Of this amount, $317 million will be on deposit in the
TSRF, while another $41 million will remain on deposit in the CRF. The
TSRF has an opening balance of $287 million, supplemented by a required
payment of $15 million and an extraordinary deposit of $65 million from
surplus 1996-97 monies. The $9 million on deposit in the Revenue
Accumulation Fund will be drawn down as planned. The previously planned
deposit of $85 million to the CRF, projected earlier to be received from
contractual efforts to maximize Federal revenue, is not expected to
materialize this year.

On January 21, 1994, the State entered into a settlement with Delaware
with respect to State of Delaware v. State of New York, which is
discussed below at State Litigation. The State made an immediate $35
million payment and agreed to make a $33 million annual payment in each
of the next five fiscal years. The State has not settled with other
parties to the litigation and will continue to incur litigation expenses
as to those claims.

On November 16, 1993, the Court of Appeals, the State's highest court,
affirmed the decision of a lower court in three actions, which declared
unconstitutional State actuarial funding methods for determining State
and local contributions to the State employee retirement system.
Following the decision, the State Comptroller developed a plan to phase
in a constitutional funding method and to restore prior funding levels
of the retirement systems over a four-year period. The plan is not
expected to require the State to make additional contributions with
respect to the 1993-94 fiscal year nor to materially and adversely
affect the State's financial condition thereafter. Through fiscal year
1998-99, the State expects to contribute $643 million more to the
retirement plans than would have been required under the prior funding
method.

Future Fiscal Years. There can be no assurance that the State will not
face substantial potential budget gaps in the future resulting from a
significant disparity between tax revenues projected from a lower
recurring receipts base and the spending required to maintain State
programs at current levels. To address any potential budgetary

Page 6                                                                   

imbalance, the State may need to take significant actions to align
recurring receipts and disbursements. 

Indebtedness. As of March 31, 1995, the total amount of long-term State
general obligation debt authorized but unissued stood at $1.789 billion.
As of the same date, the State had approximately $5.181 billion in
general obligation debt and $149.3 million of Bond Anticipation Notes
("BANS") outstanding.

As of March 31, 1995, $17.980 billion of bonds, issued in connection
with lease-purchase and contractual obligation financings of State
capital programs, were outstanding. The total amount of outstanding
State-supported debt as of March 31, 1995 was $27.913 billion. Total
State-related debt (which includes the State-supported debt, moral
obligation and certain other financings and State-guaranteed debt) was
$36.1 billion.

The State anticipates that its borrowings for capital purposes during
the State's 1995-96 fiscal year will consist of $248 million in general
obligation bonds and BANS and $186 million in general obligation
commercial paper. The State's commercial paper program is expected to
have an average of $287 million outstanding during 1997-98. The
projection of the State regarding its borrowings for the 1995-96 fiscal
year may change if actual receipts fall short of State projections or if
other circumstances require.

In June 1990, legislation was enacted creating the New York Local
Government Assistance Corporation ("LGAC"), a public benefit corporation
empowered to issue long-term obligations to fund certain payments to
local governments traditionally funded through the State's annual
seasonal borrowing. As of June, 1995, LGAC had issued its bonds and
notes to provide net proceeds of $4.7 billion, and has been authorized
to issue its bonds to provide net proceeds of up to $529 million during
the State's 1995-96 fiscal year to redeem notes sold in June 1995. The
LGAC program was completed in 1995-96 with the issuance of the last
installment of authorized bond sales.

The Legislature passed a proposed constitutional amendment which would
permit the State subject to certain restrictions to issue revenue bonds
without voter referendum. Among the restrictions proposed is that such
bonds would not be backed by the full faith and credit of the State. The
Governor intends to submit changes to the proposed amendment, which
before becoming effective must be passed again by the next separately-
elected Legislature and approved by voter referendum at a general
election. The earliest such an amendment could take effect would be in
November 1995.

Ratings. Moody's rating of the State's general obligation bonds stood at
A as of September 1995, and S&P's rating stood at A-. Previously,
Moody's lowered its rating to A on June 6, 1990, its rating having been
A1 since May 27, 1986. S&P lowered its rating from A to A- on January
13, 1992. S&P's previous ratings were A from March 1990 to January 1992,
AA- from August 1987 to March 1990 and A+ from November 1982 to August
1987.

(2) The City and the Municipal Assistance Corporation ("MAC"): The City
accounts for approximately 41% of the State's population and personal
income, and the City's financial health affects the State in numerous
ways.

In response to the City's fiscal crisis in 1975, the State took a number
of steps to assist the City in returning to fiscal stability. Among
other actions, the State Legislature (i) created MAC to assist with long-
term financing for the City's short-term debt and other cash
requirements and (ii) created the State Financial Control Board (the
"Control Board") to review and approve the City's budgets and City four-
year financial plans (the financial plans also apply to certain City-
related public agencies (the "Covered Organizations")).

Over the past three years, the rate of economic growth in the City has
slowed substantially, and the City's economy is currently in recession.
The Mayor is responsible for preparing the City's four-year financial
plan, including the City's current financial plan. The City Comptroller
has issued reports concluding that projected revenues may be less and
future expenditures may be greater than those forecast in the financial
plan.

Pursuant to State law, the City prepares a four-year annual financial
plan, which is reviewed and revised on a quarterly basis and which
includes the City's capital, revenue and expense projections. The City
is required to submit its financial plans to review bodies, including
the Control Board. If the City were to experience certain adverse
financial circumstances, including the occurrence or the substantial
likelihood and imminence of the occurrence of an annual operating
deficit of more than $100 million or the loss of access to the public

Page 7                                                                   

credit markets to satisfy the City's capital and seasonal financial
requirements, the Control Board would be required by State law to
exercise certain powers, including prior approval of City financial
plans, proposed borrowings and certain contracts. 

The City depends on the State for State aid both to enable the City to
balance its budget and to meet its cash requirements. If the State
experiences revenue shortfalls or spending increases beyond its
projections during its 1996 fiscal year or subsequent years, such
developments could result in reductions in projected State aid to the
City. In addition, there can be no assurance that State budgets in
future fiscal years will be adopted by the April 1 statutory deadline
and that there will not be adverse effects on the City's cash flow and
additional City expenditures as a result of such delays. 

The City projections set forth in its financial plan are based on
various assumptions and contingencies which are uncertain and which may
not materialize. Changes in major assumptions could significantly affect
the City's ability to balance its budget as required by State law and to
meet its annual cash flow and financing requirements. Such assumptions
and contingencies include the timing of any regional and local economic
recovery, the absence of wage increases in excess of the increases
assumed in its financial plan, employment growth, provision of State and
Federal aid and mandate relief, State legislative approval of future
State budgets, levels of education expenditures as may be required by
State law, adoption of future City budgets by the New York City Council,
and approval by the Governor or the State Legislature and the
cooperation of MAC with respect to various other actions proposed in
such financial plan.

The City's ability to maintain a balanced operating budget is dependent
on whether it can implement necessary service and personnel reduction
programs successfully. As discussed above, the City must identify
additional expenditure reductions and revenue sources to achieve
balanced operating budgets for fiscal years 1996 and thereafter. Any
such proposed expenditure reductions will be difficult to implement
because of their size and the substantial expenditure reductions already
imposed on City operations in the past two years.

Attaining a balanced budget is also dependent upon the City's ability to
market its securities successfully in the public credit markets. The
City's financing program for fiscal years 1996 through 1999 contemplates
the issuance of $9.7 billion of general obligation bonds primarily to
reconstruct and rehabilitate the City's infrastructure and physical
assets and to make capital investments. In addition, the City issues
revenue and tax anticipation notes to finance its seasonal working
capital requirements. The terms and success of projected public sales of
City general obligation bonds and notes will be subject to prevailing
market conditions at the time of the sale, and no assurance can be given
that the credit markets will absorb the projected amounts of public bond
and note sales. Future developments concerning the City and public
discussion of such developments, the City's future financial needs and
other issues may affect the market for outstanding City general
obligation bonds and notes. If the City were unable to sell its general
obligation bonds and notes, it would be prevented from meeting its
planned operating and capital expenditures.

1996-99 Financial Plan. On July 11, 1995, the City submitted to the
Control Board the 1996-99 Financial Plan, which relates to the City, the
Board of Education and the City University of New York. The 1996-99
Financial Plan is based on the City's expense and capital budgets for
the City's 1996 fiscal year, which were adopted on June 14, 1995, and
sets forth proposed actions by the City for the 1996 fiscal year to
close substantial projected budget gaps resulting from lower than
projected tax receipts and other revenues and greater than projected
expenditures. In addition to substantial proposed agency expenditure
reductions and productivity, efficiency and labor initiatives negotiated
with the City's labor unions, the 1996-99 Financial Plan reflects a
strategy to substantially reduce spending for entitlements for the 1996
and subsequent fiscal years.

The 1996-99 Financial Plan also sets forth projections for the 1997
through 1999 fiscal years and outlines a proposed gap-closing program to
close projected budget gaps of $888 million, $1.5 billion and $1.4
billion for the 1997, 1998 and 1999 fiscal years, respectively, after
successful implementation of the $3.1 billion gap-closing program for
the 1996 fiscal year. The proposed gap-closing actions, a substantial
number of which are not specified in detail, include various actions
which may be subject to State or Federal approval.

On July 24, 1995, the City Comptroller issued a report on the 1996-99
Financial Plan. The report concluded that the 1996-99 Financial Plan
includes total risks of $749 million to $1.034 billion for the 1996

Page 8                                                                   

fiscal year. With respect to the 1997-99 fiscal years, the report noted
that the gap-closing program in the 1996-99 Financial Plan does not
include information about how the City will implement the various gap-
closing programs, and that the entitlement cost containment and revenue
initiatives will require approval of the State legislature. The report
estimated that the 1996-99 Financial Plan includes total risks of $2.0
billion to $2.5 billion in the 1997 fiscal year, $2.8 billion to $3.3
billion in the 1998 fiscal year, and $2.9 billion to $3.4 billion in the
1999 fiscal year.

On December 16, 1994, the City Comptroller issued a report noting that
the capacity of the City to issue general obligation debt could be
greatly reduced in future years due to the decline in value of taxable
real property. The report concluded that the debt incurring power of the
City would likely be curtailed substantially in the 1997 and 1998 fiscal
years.

On July 21, 1995, the staff of the Control Board issued a report on the
1996-99 Financial Plan which identified risks of $873 million, $2.1
billion, $2.8 billion and $2.8 billion for the 1996 through 1999 fiscal
years, respectively.

On July 24, 1995, the staff of the OSDC issued a report on the 1996-99
Financial Plan. The report concluded that there remains a budget gap for
the 1996 fiscal year of $392 million, largely because the City and its
unions have yet to reach an agreement on how to achieve $160 million in
unspecified labor savings and the remaining $100 million in recurring
health insurance savings from last year's agreement. The report further
noted that growth in City revenues is being constrained by the weak
economy in the City, which is likely to be compounded by the slowing
national economy, and that there is a likelihood of a national recession
during the course of the 1996-99 Financial Plan. Moreover, the report
noted that State and Federal budgets are undergoing tumultuous changes,
and that the potential for far-reaching reductions in intergovernmental
assistance is clearly on the horizon, with greater uncertainty about the
impact on City finances and services.

Given the foregoing factors, there can be no assurance that the City
will continue to maintain a balanced budget, or that it can maintain a
balanced budget without additional tax or other revenue increases or
reductions in City services, which could adversely affect the City's
economic base.

The City is a defendant in a significant number of lawsuits. Such
litigation includes, but is not limited to, actions commenced and claims
asserted against the City arising out of alleged constitutional
violations, torts, breaches of contracts, and other violations of law
and condemnation proceedings. While the ultimate outcome and fiscal
impact, if any, on the proceedings and claims are not currently
predictable, adverse determinations in certain of them might have a
material adverse effect upon the City's ability to carry out its
financial plan. As of June 30, 1994, the City estimated its potential
future liability in respect of outstanding claims to be approximately
$2.6 billion. The 1996-99 Financial Plan includes provisions for
judgments and claims of $279 million, $236 million, $251 million and
$264 million for the 1996 through 1999 fiscal years, respectively.

Ratings. As of March 1996, Moody's rating of the City's general
obligation bonds stood at Baa1 and S&P's rating stood at A-.

On July 10, 1995, S&P revised downward its rating on City general
obligation bonds from A- to BBB+ and removed City bonds from
CreditWatch. S&P stated that "structural budgetary balance remains
elusive because of persistent softness in the City's economy,
highlighted by weak job growth and a growing dependence on the
historically volatile financial services sector." Other factors
identified by S&P in lowering its rating on City bonds included a trend
of using one-time measures, including debt refinancings, to close
projected budget gaps, dependence on unratified labor savings to help
balance financial plans, optimistic projections of additional Federal
and State aid or mandate relief, a history of cash flow difficulties
caused by State budget delays and continued high debt levels. Fitch
Investors Service, Inc. continues to rate the City general obligations
bond A-. Moody's rating for City general obligation bonds is Baa1.

On February 11, 1991, Moody's had lowered its rating from A. Previously,
Moody's had raised its rating to A in May 1988, to Baa1 in December
1986, to Baa in November 1983 and to Ba1 in November 1981. S&P had
raised its rating to A- in November 1987, to BBB+ in July 1985 and to
BBB in March 1981.

As of June 30, 1995, the City and MAC had, respectively, $23.258 billion
and $4.033 billion of outstanding net long-term indebtedness.

(3) The State Agencies: Certain Agencies of the State have faced
substantial financial difficulties which could adversely affect the

Page 9                                                                   

ability of such Agencies to make payments of interest on, and principal
amounts of, their respective bonds. The difficulties have in certain
instances caused the State (under so-called "moral obligation"
provisions which are non-binding statutory provisions for State
appropriations to maintain various debt service reserve funds) to
appropriate funds on behalf of the Agencies. Moreover, it is expected
that the problems faced by these Agencies will continue and will require
increasing amounts of State assistance in future years. Failure of the
State to appropriate necessary amounts or to take other action to permit
those Agencies having financial difficulties to meet their obligations
could result in a default by one or more of the Agencies. Such default,
if it were to occur, would be likely to have a significant adverse
effect on investor confidence in, and therefore the market price of,
obligations of the defaulting Agencies. In addition, any default in
payment on any general obligation of any Agency whose bonds contain a
moral obligation provision could constitute a failure of certain
conditions that must be satisfied in connection with Federal guarantees
of City and MAC obligations and could thus jeopardize the City's long-
term financing plans. 

As of September 30, 1993, the State reported that there were eighteen
Agencies that each had outstanding debt of $100 million or more. These
eighteen Agencies had an aggregate of $63.5 billion of outstanding debt,
including refunding bonds, of which $7.7 billion was moral obligation
debt of the State and $19.3 billion was financed under lease-purchase or
contractual obligation financing arrangements.

(4) State Litigation: The State is a defendant in numerous legal
proceedings pertaining to matters incidental to the performance of
routine governmental operations. Such litigation includes, but is not
limited to, claims asserted against the State arising from alleged
torts, alleged breaches of contracts, condemnation proceedings, and
other alleged violations of State and Federal laws. Included in the
State's outstanding litigation are a number of cases challenging the
constitutionality or the adequacy and effectiveness of a variety of
significant social welfare programs primarily involving the State's
mental hygiene programs. Adverse judgments in these matters generally
could result in injunctive relief coupled with prospective changes in
patient care which could require substantial increased financing of the
litigated programs in the future. 

The State is also engaged in a variety of claims wherein significant
monetary damages are sought. Actions commenced by several Indian nations
claim that significant amounts of land were unconstitutionally taken
from the Indians in violation of various treaties and agreements during
the eighteenth and nineteenth centuries. The claimants seek recovery of
approximately six million acres of land as well as compensatory and
punitive damages.

Adverse developments in the foregoing proceedings or new proceedings
could adversely affect the financial condition of the State in the future.

(5) Other Municipalities: Certain localities in addition to New York
City could have financial problems leading to requests for additional
State assistance. The potential impact on the State of such actions by
localities is not included in projections of State receipts and
expenditures in the State's 1996-97 and 1997-98 fiscal years.

Fiscal difficulties experienced by the City of Yonkers ("Yonkers")
resulted in the creation of the Financial Control Board for the City of
Yonkers (the "Yonkers Board") by the State in 1984. The Yonkers Board is
charged with oversight of the fiscal affairs of Yonkers. Future actions
taken by the Governor or the State Legislature to assist Yonkers could
result in allocation of State resources in amounts that cannot yet be
determined.

Municipalities and school districts have engaged in substantial short-
term and long-term borrowings. In 1993, the total indebtedness of all
localities in the State was approximately $17.7 billion. State law
requires the Comptroller to review and make recommendations concerning
the budgets of those local government units other than New York City
authorized by State law to issue debt to finance deficits during the
period that such deficit financing is outstanding. Fifteen localities
had outstanding indebtedness for state financing at the close of their
fiscal year ending in 1993.

Certain proposed Federal expenditure reductions could reduce, or in some
cases eliminate, Federal funding of some local programs and accordingly
might impose substantial increased expenditure requirements on affected
localities. If the State, New York City or any of the Agencies were to
suffer serious financial difficulties jeopardizing their respective
access to the public credit markets, the marketability of notes and
bonds issued by localities within the State, including notes or bonds in
the New York Insured Trust, could be adversely affected. Localities also

Page 10                                                                  

face anticipated and potential problems resulting from certain pending
litigation, judicial decisions, and long-range economic trends. The
longer-range potential problems of declining urban population,
increasing expenditures, and other economic trends could adversely
affect localities and require increasing State assistance in the future.

(6) Other Issuers of New York Municipal Obligations. There are a number
of other agencies, instrumentalities and political subdivisions of the
State that issue Municipal Obligations, some of which may be conduit
revenue obligations payable from payments from private borrowers. These
entities are subject to various economic risks and uncertainties, and
the credit quality of the securities issued by them may vary
considerably from the credit quality of obligations backed by the full
faith and credit of the State.

The foregoing information constitutes only a brief summary of some of
the general factors which may impact certain issuers of Bonds and does
not purport to be a complete or exhaustive description of all adverse
conditions to which the issuers of Bonds held by the New York Trusts are
subject. Additionally, many factors including national economic, social
and environmental policies and conditions, which are not within the
control of the issuers of the Bonds, could affect or could have an
adverse impact on the financial condition of the issuers. The Sponsor is
unable to predict whether or to what extent such factors or other
factors may affect the issuers of the Bonds, the market value or
marketability of the Bonds or the ability of the respective issuers of
the Bonds acquired by the New York Trusts to pay interest on or
principal of the Bonds.
