  (The First Trust (registered trademark) Combined Series 251)
                       Prospectus - Part I
    

   
THIS PART I OF THE PROSPECTUS MAY NOT BE DISTRIBUTED UNLESS ACCOMPANIED 
BY THE PART II OF THE PROSPECTUS DATED AUGUST 9, 1995. BOTH PARTS 
I AND II OF THE PROSPECTUS SHOULD BE RETAINED FOR FUTURE REFERENCE.
    

   
Alabama Insured Trust, Series 28 (the "Alabama Insured Trust"), 
consists of a portfolio of interest-bearing obligations issued 
by or on behalf of the State of Alabama or certain United States 
Territories which, in the opinion of recognized bond counsel to 
the issuing authorities, provide income which is exempt from Federal 
income tax, Alabama income tax and local tax, as detailed below.
    

   
The objectives of the Trust are conservation of capital and income 
exempt from Federal and applicable state and local income taxes. 
The objectives are, of course, dependent upon the continuing ability 
of the issuers, obligors and/or insurers to meet their respective 
obligations.
    

   
The Alabama Insured Trust consists of seven obligations of issuers 
located in Alabama. The Bond issues in the Trust are either general 
obligations of governmental entities or are revenue bonds payable 
from the income of a specific project or authority. The Bonds 
in the Trust are divided by purpose of issue and represent the 
percentage of aggregate principal amount of the Bonds as indicated 
by the following table: 
    

   
        Number                                          Portfolio

        _________       __________________              __________
        2               Water                           34.85%
        2               Health Care                     33.45%
        1               Water and Sewer                 17.42%
        1               University and School           10.45%
        1               Utility                          3.83%
    

   
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 
96%. The four largest such issues represent approximately 17% 
each. None of the Bonds in the Trust are subject to call within 
five years of the Initial Date of Deposit, although certain Bonds 
may be subject to an extraordinary call.  See "Alabama Insured 
Trust, Series 28-Portfolio" contained herein and "Description 
of Bond Ratings" in the Information Supplement.
    

   
All of the Bonds included in the Trust are insured. The insurance 
guarantees the timely payment of principal and interest of the 
Bonds, but does not guarantee the value of the Bonds or the Units. 
As a result of the insurance, the Bonds and the Units in the Trust 
have received a rating of "AAA" by Standard & Poor's Ratings Services, 
a division of The McGraw-Hill Companies, Inc. ("Standard & Poor's"). 
The percentage of the aggregate face amount insured by each insurance 
company is:

__________________
(1)     Many unit investment trusts comprised of municipal securities 
issue a number of Units such that each Unit represents approximately 
$1,000 principal amount of underlying securities. For the Alabama 
Insured Trust, the Sponsor has elected to provide that number 
of Units which will establish as close as possible as of the opening 
of business on the Initial Date of Deposit a Public Offering Price 
per Unit of $1,000. Because certain of the Bonds in the Trust 
may from time to time under certain circumstances be sold or redeemed 
or will be called or will mature in accordance with their terms, 
there is no guarantee that the value of each Unit at the Trust's 
termination will be equal to the Principal Amount (Par Value) 
of Bonds per Unit stated above.

(2)     The sales charge is reduced by a discount of $7.50 per Unit 
for purchases between $500,000 and $999,999 and $15.00 per Unit 
for purchases in excess of $1,000,000. Such reductions for volume 
purchases are not applicable to sales made pursuant to a "wrap 
fee account" or similar arrangement as discussed in "Public Offering" 
in Part II of the Prospectus.

(3)     Anyone ordering Units for settlement after the First Settlement 
Date will pay accrued interest from such date to the date of settlement 
(normally three business days after order) less distributions 
from the Interest Account subsequent to the First Settlement Date. 
For purchases settling on the First Settlement Date, no accrued 
interest will be added to the Public Offering Price. After the 
initial offering period, the Sponsor's Repurchase Price per Unit 
will be determined as described under the caption "Will There 
Be a Secondary Market?" in Part II of this Prospectus.

(4)     See "How May Units be Redeemed?" in Part II of this Prospectus.

                      Alabama Risk Factors

   
The financial condition of the State of Alabama is affected by 
various national, economic, social and environmental policies 
and conditions. Additionally, Constitutional and statutory limitations 
imposed on the State and its local governments concerning taxes, 
bond indebtedness and other matters may constrain the revenue-generating 
capacity of the State and its local governments and, therefore, 
the ability of the issuers of the Bonds to satisfy their obligations.
    

   
The economic vitality of the State and its various regions and, 
therefore, the ability of the State and its local governments 
to satisfy the Bonds, are affected by numerous factors. The economy 
of the State continues to be dependent on manufacturing, agriculture 
and mining. Alabama's economy has experienced a major trend toward 
industrialization over the past two decades. In recent years, 
the importance of service industries to the State's economy has 
increased significantly.
    

   
Deterioration of economic conditions could adversely affect both 
tax and other governmental revenues, as well as revenues to be 
used to service various revenue obligations, such as industrial 
development obligations. Such difficulties could adversely affect 
the market value of the Bonds held by the Alabama Insured Trust 
and thereby adversely affect Unit holders.
    

   
Further information concerning Alabama risk factors may be obtained 
upon written or telephonic request to the Trustee as described 
in "INFORMATION AS TO SPONSOR, TRUSTEE AND EVALUATOR-Who is the 
Trustee?" in Part II of this Prospectus.
    
                       Alabama Tax Status

In the opinion of Balch & Bingham, Birmingham, Alabama, Special 
Counsel to the Fund for Alabama tax matters, under existing Alabama 
income tax law applicable to taxpayers whose income is subject 
to Alabama income taxation: 

The Alabama Trust is not taxable as a corporation for purposes 
of the Alabama income tax. 

Income of the Alabama Trust, to the extent it is taxable, will 
be taxable to the Unit holders, not the Alabama Trust. 

Each Unit holder's distributive share of the Alabama Trust's net 
income will be treated as the income of the Unit holder for purposes 
of the Alabama income tax. 

Interest on obligations of the State of Alabama and subdivisions 
thereof and on bona fide tax-exempt obligations of the United 
States' Possessions held by the Alabama Trust which is exempt 
from Alabama income tax will retain its tax-exempt character when 
the distributive share thereof is distributed or deemed distributed 
to each Unit holder. Any proceeds paid to the Alabama Trust under 
insurance policies issued to the Sponsor or under individual policies 
obtained by the Sponsor, the issuer or underwriter of the respective 
obligations which represent maturing interest on defaulted obligations 
held by the Trustee will be exempt from Alabama income tax if 
and to the same extent as such interest would be exempt from such 
taxes if paid directly by the issuer of such obligations.

Each Unit holder will, for purposes of the Alabama income tax, 
treat his distributive share of gains realized upon the sale or 
other disposition of the Bonds held by the Alabama Trust as though 
the Bonds were sold or disposed of directly by the Unit holders. 

Gains realized on the sale or redemption of Units by Unit holders, 
who are subject to the Alabama income tax, will be includable 
in the Alabama income of such Unit holders. 

For information with respect to the Federal income tax status 
and other tax matters, see "What Is the Federal Tax Status of 
Unit Holders?" in Part II of this Prospectus. 

            Federal and Alabama State Tax-Free Income

The following table shows the approximate marginal taxable yields 
for individuals that are equivalent to tax-exempt yields under 
combined Federal and state taxes, using published Federal tax 
rates and state tax rates scheduled to be in effect in 1995. The 
table incorporates increased tax rates for higher-income taxpayers 
that were included in the Revenue Reconciliation Act of 1993. 
For cases in which more than one state bracket falls within a 
Federal bracket, the higher state bracket is combined with the 
Federal bracket. The combined

Page 4 of 12


state and Federal tax rates shown reflect the fact that state 
tax payments are currently deductible for Federal tax purposes. 
The table illustrates what you would have to earn on taxable investments 
to equal the tax-exempt yield for your income tax bracket. The 
taxable equivalent yields may be somewhat higher than the equivalent 
yields indicated in the following table for those individuals 
who have adjusted gross incomes in excess of $114,700. The table 
does not reflect the effect of the limitations on itemized deductions 
and the deduction for personal exemptions. They were designed 
to phase out certain benefits of these deductions for higher income 
taxpayers. These limitations, in effect, raise the maximum marginal 
Federal tax rate to approximately 44% for taxpayers filing a joint 
return and entitled to four personal exemptions and to approximately 
41% for taxpayers filing a single return entitled to only one 
personal exemption. These limitations are subject to certain maximums, 
which depend on the number of exemptions claimed and the total 
amount of the taxpayer's itemized deductions. For example, the 
limitation on itemized deductions will not cause a taxpayer to 
lose more than 80% of his allowable itemized deductions, with 
certain exceptions.

Neither Cost of Bonds to Sponsor nor Profit or (Loss) to Sponsor 
reflects underwriting profits or losses received or incurred by 
the Sponsor through its participation in underwriting syndicates 
but such amounts reflect the cost of insurance obtained by the 
Sponsor prior to the Initial Date of Deposit for individual Bonds. 
The Offering and Bid Prices of Bonds were determined by Securities

of the Sponsor.

(2) All ratings are by Standard & Poor's unless otherwise indicated. 
Such ratings were obtained from a municipal bond information reporting 
service. The "AAA" rating on each Bond is a result of insurance. 
Insurance, however, does not cover certain market risks associated 
with fixed income securities such as accelerated payments of principal, 
mandatory redemptions prior to maturity or interest rate risks. 
See "Why and How are the Insured Trusts Insured?" in Part II of 
this Prospectus and "Description of Bond Ratings" in the Information 
Supplement.
    

   
(3) There is shown under this heading the year in which each issue 
of Bonds initially is redeemable and the redemption price for 
that year or, if currently redeemable, the redemption price in 
effect on the Initial Date of Deposit. Issues of Bonds are redeemable 
at declining prices (but not below par value) in subsequent years 
except for original issue discount Bonds which are redeemable 
at prices based on the issue price plus the amount of original 
issue discount accreted to the redemption date plus, if applicable, 
some premium, the amount of which will decline in subsequent years. 
"S.F." indicates a sinking fund is established with respect to 
an issue of Bonds. In addition, certain Bonds in the portfolio 
may be redeemed in whole or in part other than by operation of 
the stated redemption or sinking fund provisions under certain 
unusual or extraordinary circumstances specified in the instruments 
setting forth the terms and provisions of such Bonds. See "What 
are Certain General Matters Relating to the Trusts?-Risk Factors" 
in Part II of this Prospectus for a discussion of Bond redemptions 
and a description of certain of such unusual or extraordinary 
circumstances under which Bonds may be redeemed. Distributions 
will generally be reduced by the amount of the income which would 
otherwise have been paid with respect to redeemed Bonds and there 
will be distributed to Unit holders the principal amount and any 
premium received on such redemption (except to the extent the 
proceeds of the redeemed Bonds are used to pay for Unit redemptions). 
The estimated current return and the estimated long-term return 
in this event may be affected by such redemptions. For the Federal 
and state tax effect on Unit holders of such redemptions and resultant 
distributions, see "Rights of Unit Holders-What is the Federal 
Tax Status of Unit Holders?" in Part II of this Prospectus and 
"Alabama Tax Status."

on our audit.
    

   
We conducted our audit in accordance with generally accepted auditing 
standards. Those standards require that we plan and perform the 
audit to obtain reasonable assurance about whether the statement 
of net assets is free of material misstatement. An audit includes 
examining, on a test basis, evidence supporting the amounts and 
disclosures in the statement of net assets. Our procedures included 
confirmation of the letter of credit held by the Trustee and deposited 
in the Trust on August 9, 1995. An audit also includes assessing 
the accounting principles used and significant estimates made 
by the Sponsor, as well as evaluating the overall presentation 
of the statement of net assets. We believe that our audit of the 
statement of net assets provides a reasonable basis for our opinion. 
    

   
In our opinion, the statement of net assets referred to above 
presents fairly, in all material respects, the financial position 
of Alabama Insured Trust, Series 28, included in The First Trust 
Combined Series 251, at the opening of business on August 9, 1995 
in conformity with generally accepted accounting principles.

     (The First Trust (registered trademark) Combined Series 251)
                       Prospectus - Part I
    

   
THIS PART I OF THE PROSPECTUS MAY NOT BE DISTRIBUTED UNLESS ACCOMPANIED 
BY THE PART II OF THE PROSPECTUS DATED AUGUST 9, 1995. BOTH PARTS 
I AND II OF THE PROSPECTUS SHOULD BE RETAINED FOR FUTURE REFERENCE.
    

   
Connecticut Insured Trust, Series 15 (the "Connecticut Insured 
Trust"), consists of a portfolio of interest-bearing obligations 
issued by or on behalf of the State of Connecticut or certain 
United States Territories which, in the opinion of recognized 
bond counsel to the issuing authorities, provide income which 
is exempt from Federal income tax, Connecticut income tax and 
local tax, as detailed below.
    

   
The objectives of the Trust are conservation of capital and income 
exempt from Federal and applicable state and local income taxes. 
The objectives are, of course, dependent upon the continuing ability 
of the issuers, obligors and/or insurers to meet their respective 
obligations.
    

   
The Connecticut Insured Trust consists of six obligations of issuers 
located in Connecticut. The Bond issues in the Trust are either 
general obligations of governmental entities or are revenue bonds 
payable from the income of a specific project or authority. The 
Bonds in the Trust are divided by purpose of issue and represent 
the percentage of aggregate principal amount of the Bonds as indicated 
by the following table: 
    

   
        Number                                          Portfolio
        of Issues       Purpose of Issue                Percentage
        _________       __________________              __________
        1               General Obligation              16.67%
        2               Health Care                     33.33%
        1               Water                           23.33%
        1               Single Family Housing           16.67%
        1               Transportation                  10.00%
    

   
Each Bond issue represents 10% or more of the aggregate principal 
amount of the Bonds in the Trust. The largest such issue represents 
approximately 23%. None of the Bonds in the Trust are subject 
to call within five years of the Initial Date of Deposit, although 
certain Bonds may be subject to an extraordinary call. Approximately 
33% of the aggregate principal amount (approximately 35% of the 
aggregate offering price) of the Bonds in the Trust were purchased 
at a premium over par value. Certain of these Bonds are subject 
to redemption pursuant to call provisions in approximately 7-10 
years after the Initial Date of Deposit. See "Connecticut Insured 
Trust, Series 15-Portfolio" contained herein and "Description 
of Bond Ratings" in the Information Supplement.
    

   
All of the Bonds included in the Trust are insured. The insurance 
guarantees the timely payment of principal and interest of the 
Bonds, but does not guarantee the value of the Bonds or the Units. 
As a result of the insurance, the Bonds and the Units in the Trust 
have received a rating of "AAA" by Standard & Poor's Ratings Services, 
a division of The McGraw-Hill Companies, Inc. ("Standard & Poor's"). 
The percentage of the aggregate face amount insured by each insurance 
company is:

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.

[FN]
________________
(1)     Many unit investment trusts comprised of municipal securities 
issue a number of Units such that each Unit represents approximately 
$1,000 principal amount of underlying securities. For the Connecticut 
Insured Trust, the Sponsor has elected to provide that number 
of Units which will establish as close as possible as of the opening 
of business on the Initial Date of Deposit a Public Offering Price 
per Unit of $1,000. Because certain of the Bonds in the Trust 
may from time to time under certain circumstances be sold or redeemed 
or will be called or will mature in accordance with their terms, 
there is no guarantee that the value of each Unit at the Trust's 
termination will be equal to the Principal Amount (Par Value) 
of Bonds per Unit stated above.

(2)     The sales charge is reduced by a discount of $7.50 per Unit 
for purchases between $500,000 and $999,999 and $15.00 per Unit 
for purchases in excess of $1,000,000. Such reductions for volume 
purchases are not applicable to sales made pursuant to a "wrap 
fee account" or similar arrangement as discussed in "Public Offering" 
in Part II of the Prospectus.

(3)     Anyone ordering Units for settlement after the First Settlement 
Date will pay accrued interest from such date to the date of settlement 
(normally three business days after order) less distributions 
from the Interest Account subsequent to the First Settlement Date. 
For purchases settling on the First Settlement Date, no accrued 
interest will be added to the Public Offering Price. After the 
initial offering period, the Sponsor's Repurchase Price per Unit 
will be determined as described under the caption "Will There 
Be a Secondary Market?" in Part II of this Prospectus.

(4)     See "How May Units be Redeemed?" in Part II of this Prospectus.

(1)     Supervisory Fees are payable to an affiliate of the Sponsor. 
Administrative Fees are payable to the Sponsor.

(2)     The Trust (and therefore Unit holders) will bear all or 
a portion of its organizational costs (including costs of preparing 
the registration statement, the trust indenture and other closing 
documents, registering Units with the Securities and Exchange 
Commission and states, the initial audit of the Trust's portfolio 
and the initial fees and expenses of the Trustee but not including 
the expenses incurred in the printing of preliminary and final 
prospectuses, and expenses incurred in the preparation and printing 
of brochures and other advertising materials and any other selling 
expenses) as is common for mutual funds. Total organizational 
expenses will be amortized over a five year period. See "What 
are the Expenses and Charges?" in Part II of this Prospectus and 
"Statement of Net Assets." Historically, the sponsors of unit 
investment trusts have paid all the costs of establishing such trusts.

(3)     Additional information concerning distributions of interest 
and principal can be found in "How are Interest and Principal 
Distributed?" in Part II of this Prospectus.

(4)     See "What are Estimated Long-Term Return and Estimated Current 
Return?" in Part II of this Prospectus for a description of how 
these returns are calculated. 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,

                    Connecticut Risk Factors

   
The financial condition of the State of Connecticut is affected 
by various national, economic, social and environmental policies 
and conditions. Additionally, Constitutional and statutory limitations 
imposed on the State and its local governments concerning taxes, 
bond indebtedness and other matters may constrain the revenue-generating 
capacity of the State and its local governments and, therefore, 
the ability of the issuers of the Bonds to satisfy their obligations. 
Historically, the State has experienced significant revenue shortfalls. 
    

   
The economic vitality of the State and its various regions and, 
therefore, the ability of the State and its local governments 
to satisfy the Bonds, are affected by numerous factors. The economy 
of the State continues to be dependent on manufacturing, especially 
defense-related business. Reductions in defense spending have 
already had a substantial adverse effect on Connecticut's economy, 
and labor force reductions are scheduled over the next four years. 
    

   
The State is a party to numerous lawsuits in which an adverse 
final decision could materially affect the State's governmental 
operations and consequently its ability to pay debt service on 
its obligations. 
    

   
All outstanding general obligation bonds of the State are rated 
AA- by Standard and Poor's and Aa by Moody's. 
    

   
Further information concerning Connecticut risk factors may be 
obtained upon written or telephonic request to the Trustee as 
described in "Information as to Sponsor, Trustee and Evaluator 
- - Who is the Trustee?" in Part II of this Prospectus.
    


                     Connecticut Tax Status

The assets of the Connecticut Trust will consist of obligations 
(the "Bonds"), some of which have been issued by or on behalf 
of the State of Connecticut or its political subdivisions or other 
public bodies created under the laws of the State of Connecticut 
("Connecticut Bonds") and the balance of which have been issued 
by or on behalf of entities classified for relevant purposes as 
territories or possessions of the United States, including one 
or more of Puerto Rico, Guam, or the Virgin Islands, the interest 
on the obligations of which Federal law would prohibit Connecticut 
from taxing if received directly by the Unit holders. Certain 
Connecticut Bonds in the Connecticut Trust were issued prior to 
the enactment of the Connecticut income tax on the Connecticut 
taxable income of Individuals, trusts, and estates (the "Connecticut 
Income Tax"); therefore, bond counsel to the issuers of such Bonds 
did not opine as to the exemption of the interest on such Bonds 
from such tax. However, the Sponsor and special counsel to the 
Connecticut Trust for Connecticut tax matters believe that such 
interest will be so exempt. Interest on Bonds in the Connecticut 
Trust issued by other issuers, if any, is, in the opinion of bond 
counsel to such issuers, exempt from state taxation.

The Connecticut Income Tax was enacted in August 1991. Generally, 
under this tax as enacted, a Unit holder would recognize gain 
or loss for purposes of this tax upon the maturity, redemption, 
sale, or other disposition by the Connecticut Trust of an obligation 
held by it, or upon the redemption, sale, or other disposition 
of a Unit of the Connecticut Trust held by the Unit holder, to 
the same extent that gain or loss is recognized by the Unit holder 
thereupon for Federal income tax purposes. However, on June 19, 
1992, Connecticut legislation was adopted that provides that gains 
and losses from the sale or exchange of Connecticut Bonds held 
as capital assets will not be taken into account for purposes 
of the Connecticut Income Tax for taxable years starting on or 
after January 1, 1992. Regulations effective for taxable years 
starting on or after January 1, 1994, clarify that this provision 
also applies to gain or loss recognized by a Unit holder upon 
the maturity or redemption of a Connecticut Bond held by the Connecticut 
Trust. However, it is not clear whether this provision would apply, 
to the extent attributable to Connecticut Bonds held by the Connecticut 
Trust, to gain or loss recognized by a Unit holder upon the redemption, 
sale, or other disposition of a Unit of the Connecticut Trust 
held by the Unit holder. Unit holders are urged to consult their 
own tax advisors in this regard.

In the opinion of Day, Berry & Howard, special counsel to the 
Fund for Connecticut tax matters, which relies explicitly on the 
opinion of Chapman and Cutler regarding Federal income tax matters, 
under existing Connecticut law:

1.      The Connecticut Trust is not liable for any tax on or measured 
by net income imposed by the State of Connecticut.

2.      Interest income from a Bond issued by or on behalf of the 
State of Connecticut, any political subdivision thereof, or public 
instrumentality, state or local authority, district, or similar 
public entity created under the laws of the State of Connecticut 
(a "Connecticut Bond"), or from a Bond issued by United States 
territories or possessions the interest on which Federal law would 
prohibit Connecticut from taxing if received directly by a Unit 
holder from the issuer thereof, is not taxable under the Connecticut 
tax on the Connecticut taxable income of individuals, trusts, 
and estates (the "Connecticut Income Tax") when such interest 
is received by the Connecticut Trust or distributed by it to such 
a Unit holder.

3.      Insurance proceeds received by the Connecticut Trust representing 
maturing interest on defaulted Bonds held by the Connecticut Trusts 
are not taxable under the Connecticut Income Tax if, and to the 
same extent as, such interest would not be taxable thereunder 
if paid directly to the Connecticut Trust by the issuer of such Bonds.

4.      Gains and losses recognized by a Unit holder for Federal income 
tax purposes upon the maturity, redemption, sale, or other disposition 
by the Connecticut Trust of a Bond held by the Connecticut Trust 
or upon the redemption, sale, or other disposition of a Unit of 
the Connecticut Trust held by a Unit holder are taken into account 
as gains or losses, respectively, for purposes of the Connecticut 
Income Tax, except that, in the case of a Unit holder holding 
a Unit of the Connecticut Trust as a capital asset, such gains 
and losses recognized upon the maturity, redemption, sale or exchange 
of a Connecticut Bond held by the Connecticut Trust are excluded 
from gains and losses taken into account for purposes of such 
tax, and no opinion is expressed as to the treatment for purposes 
of such tax of gains and losses recognized, to the extent attributable 
to Connecticut Bonds, upon the redemption, sale, or other disposition 
by a Unit holder of a Unit of the Connecticut Trust held by him.

5.      The portion of any interest income or capital gain of the 
Connecticut Trust that is allocable to a Unit holder that is subject 
to the Connecticut corporation business tax is includable in the 
gross income of such Unit holder for purposes of such tax.

6.      An interest in a Unit of the Connecticut Trust that is owned 
by or attributable to a Connecticut resident at the time of his 
death is includable in his gross estate for purposes of the Connecticut 
succession tax and the Connecticut estate tax.

For information with respect to the Federal income tax status 
and other tax matters, see "What Is the Federal Tax Status of 
Unit Holders?" in Part II of this Prospectus.

          Federal and Connecticut State Tax-Free Income

The following table shows the approximate marginal taxable yields 
for individuals that are equivalent to tax-exempt yields under 
combined Federal and state taxes, using published Federal tax 
rates and state tax rates scheduled to be in effect in 1995. The 
table incorporates increased tax rates for higher-income taxpayers 
that were included in the Revenue Reconciliation Act of 1993. 
For cases in which more than one state bracket falls within a 
Federal bracket, the higher state bracket is combined with the 
Federal bracket. The combined state and Federal tax rates shown 
reflect the fact that state tax payments are currently deductible 
for Federal tax purposes. The table illustrates what you would 
have to earn on taxable investments to equal the tax-exempt yield 
for your income tax bracket. The taxable equivalent yields may 
be somewhat higher than the equivalent yields indicated in the 
following table for those individuals who have adjusted gross 
incomes in excess of $114,700. The table does not reflect the 
effect of the limitations on itemized deductions and the deduction 
for personal exemptions. They were designed to phase out certain 
benefits of these deductions for higher income taxpayers. These 
limitations, in effect, raise the maximum marginal Federal tax 
rate to approximately 44% for taxpayers filing a joint return 
and entitled to four personal exemptions and to approximately

Page 5 of 12


41% for taxpayers filing a single return entitled to only one 
personal exemption. These limitations are subject to certain maximums, 
which depend on the number of exemptions claimed and the total 
amount of the taxpayer's itemized deductions. For example, the 
limitation on itemized deductions will not cause a taxpayer to 
lose more than 80% of his allowable itemized deductions, with 
certain exceptions.

</TABLE>
[FN]

*       The table takes into account the Connecticut income tax. The 
Connecticut income tax is based on Connecticut taxable income, 
which is not tied to Federal taxable income. Connecticut taxable 
income is equal to Connecticut adjusted gross income ("CAGI") 
(which is Federal adjusted gross income with certain modifications) 
minus the allowable personal exemption ($12,000 in the case of 
single individuals; $24,000 for married persons filing jointly). 
Although not reflected in the table, the Connecticut income tax 
provides for a personal exemption phase-out, which essentially 
doubles the effective marginal Connecticut income tax rate for 
single taxpayers whose CAGI is between $24,000 and $35,001 at 
which point the personal exemption is completely phased out. For 
married taxpayers filing a joint return, the effective marginal 
Connecticut income tax rate is doubled where CAGI is between $48,000 
and $71,001, at which point the personal exemption is completely 
phased out. In addition, as reflected in the rates shown, the 
Connecticut income tax provides for a tax credit (at varying percentages 
depending on the taxpayer's CAGI) against the income tax which 
is based on CAGI and, in effect, varies the income tax rate for 
taxpayers. Investors should consult their own tax advisors regarding 
the effect of the credit on marginal tax rates at specific CAGI levels.

at declining prices (but not below par value) in subsequent years 
except for original issue discount Bonds which are redeemable 
at prices based on the issue price plus the amount of original 
issue discount accreted to the redemption date plus, if applicable, 
some premium, the amount of which will decline in subsequent years. 
"S.F." indicates a sinking fund is established with respect to 
an issue of Bonds. In addition, certain Bonds in the portfolio

the stated redemption or sinking fund provisions under certain 
unusual or extraordinary circumstances specified in the instruments 
setting forth the terms and provisions of such Bonds. See "What 
are Certain General Matters Relating to the Trusts?-Risk Factors" 
in Part II of this Prospectus for a discussion of Bond redemptions 
and a description of certain of such unusual or extraordinary 
circumstances under which Bonds may be redeemed. Distributions 
will generally be reduced by the amount of the income which would 
otherwise have been paid with respect to redeemed Bonds and there 
will be distributed to Unit holders the principal amount and any 
premium received on such redemption (except to the extent the 
proceeds of the redeemed Bonds are used to pay for Unit redemptions). 
The estimated current return and the estimated long-term return 
in this event may be affected by such redemptions. For the Federal 
and state tax effect on Unit holders of such redemptions and resultant 
distributions, see "Rights of Unit Holders-What is the Federal 
Tax Status of Unit Holders?" in Part II of this Prospectus and

                 Idaho Advantage Trust, Series 8

             (The First Trust Combined Series 251)
                       Prospectus - Part I
    

   
This Part I of the Prospectus may not be distributed unless accompanied 
by the Part II of the Prospectus dated August 9, 1995. Both Parts 
I and II of the Prospectus should be retained for future reference.
    

   
Idaho Advantage Trust, Series 8 (the "Idaho Advantage Trust"), 
consists of a portfolio of interest-bearing obligations issued 
by or on behalf of the State of Idaho or certain United States 
Territories which, in the opinion of recognized bond counsel to 
the issuing authorities, provide income which is exempt from Federal 
income tax, Idaho income tax and local tax, as detailed below.
    

   
The objectives of the Trust are conservation of capital and income 
exempt from Federal and applicable state and local income taxes, 
although interest on certain Bonds in the Idaho Advantage Trust 
will be a preference item for purposes of the Alternative Minimum 
Tax. ACCORDINGLY, THE IDAHO ADVANTAGE TRUST MAY BE APPROPRIATE 
ONLY FOR INVESTORS WHO ARE NOT SUBJECT TO THE ALTERNATIVE MINIMUM 
TAX. The objectives are, of course, dependent upon the continuing 
ability of the issuers, obligors and/or insurers to meet their 
respective obligations.
    

   
Interest on certain of the Bonds in the Idaho Advantage Trust 
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 the Idaho Advantage Trust is an AMT preference 
item, the Idaho Advantage Trust may be more appropriate for investors 
who are not subject to AMT.
    

   
The Idaho Advantage Trust consists of eight obligations of issuers 
located in Idaho. The Bond issues in the Trust are either general 
obligations of governmental entities or are revenue bonds payable 
from the income of a specific project or authority. The Bonds 
in the Trust are divided by purpose of issue and represent the 
percentage of aggregate principal amount of the Bonds as indicated 
by the following table: 
    

   
        Number                                          Portfolio
        of Issues       Purpose of Issue                Percentage
        _________       __________________              __________

        4               General Obligation              45.22%
        2               University and School           30.89%
        2               Single Family Housing           23.89%

    

   
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 
79%. The four largest such issues represent approximately 16% 
each. None of the Bonds in the Trust are subject to call within 
five years of the Initial Date of Deposit, although certain Bonds 
may be subject to an extraordinary call. Approximately 47% of 
the aggregate principal amount (approximately 49% of the aggregate 
offering price) of the Bonds in the Trust were purchased at a 
premium over par value. Certain of these Bonds are subject to 
redemption pursuant to call provisions in approximately 6-10 years 
after the Initial Date of Deposit. See "Idaho Advantage Trust, 
Series 8-Portfolio" contained herein and "Description of Bond 
Ratings" in the Information Supplement.
    

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.

[FN]
_________________________

(1)     Many unit investment trusts comprised of municipal securities 
issue a number of Units such that each Unit represents approximately 
$1,000 principal amount of underlying securities. For the Idaho 
Advantage Trust, the Sponsor has elected to provide that number 
of Units which will establish as close as possible as of the opening 
of business on the Initial Date of Deposit a Public Offering Price 
per Unit of $1,000. Because certain of the Bonds in the Trust 
may from time to time under certain circumstances be sold or redeemed 
or will be called or will mature in accordance with their terms, 
there is no guarantee that the value of each Unit at the Trust's 
termination will be equal to the Principal Amount (Par Value) 
of Bonds per Unit stated above.

(2)     The sales charge is reduced by a discount of $7.50 per Unit 
for purchases between $500,000 and $999,999 and $15.00 per Unit 
for purchases in excess of $1,000,000. Such reductions for volume 
purchases are not applicable to sales made pursuant to a "wrap 
fee account" or similar arrangement as discussed in "Public Offering" 
in Part II of the Prospectus.

(3)     Anyone ordering Units for settlement after the First Settlement 
Date will pay accrued interest from such date to the date of settlement 
(normally three business days after order) less distributions 
from the Interest Account subsequent to the First Settlement Date. 
For purchases settling on the First Settlement Date, no accrued 
interest will be added to the Public Offering Price. After the 
initial offering period, the Sponsor's Repurchase Price per Unit 
will be determined as described under the caption "Will There 
Be a Secondary Market?" in Part II of this Prospectus.

(4)     See "How May Units be Redeemed?" in Part II of this Prospectus.

(1)     During the first year only, the Trustee has agreed to reduce 
its fee and pay expenses of the Trust in an amount (approximately 
$.73) equal to the interest that would have accrued prior to the 
expected delivery dates of Bonds included in the Portfolio that 
were purchased on a "when, as and if issued" or delayed delivery 
basis. During the first year, Estimated Annual Interest Income 
per Unit would be $52.92. Estimated Net Annual Interest Income

Relating to the Trusts?" and "What are the Expenses and Charges?"

(2)     Supervisory Fees are payable to an affiliate of the Sponsor. 
Administrative Fees are payable to the Sponsor.

(3)     The Trust (and therefore Unit holders) will bear all or 
a portion of its organizational costs (including costs of preparing 
the registration statement, the trust indenture and other closing 
documents, registering Units with the Securities and Exchange 
Commission and states, the initial audit of the Trust's portfolio 
and the initial fees and expenses of the Trustee but not including 
the expenses incurred in the printing of preliminary and final 
prospectuses, and expenses incurred in the preparation and printing 
of brochures and other advertising materials and any other selling 
expenses) as is common for mutual funds. Total organizational 
expenses will be amortized over a five year period. See "What 
are the Expenses and Charges?" in Part II of this Prospectus and 
"Statement of Net Assets." Historically, the sponsors of unit 
investment trusts have paid all the costs of establishing such 
trusts.

(5)     See "What are Estimated Long-Term Return and Estimated Current 
Return?" in Part II of this Prospectus for a description of how 
these returns are calculated. The above figures are based on estimated

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. The estimated cash flows 
for this Trust may be obtained from the Sponsor at no charge by

                       Idaho Risk Factors

   
The financial condition of the State of Idaho is affected by various 
national, economic, social and environmental policies and conditions. 
Additionally, Constitutional and statutory limitations imposed 
on the State and its local governments concerning taxes, bond 
indebtedness and other matters may constrain the revenue-generating 
capacity of the State and its local governments and, therefore, 
the ability of the issuers of the Bonds to satisfy their obligations. 
    

   
The economic vitality of the State and its various regions and, 
therefore, the ability of the State and its local governments 
to satisfy the Bonds, are affected by numerous factors. Idaho's 
economic performance over the last several years has been significantly 
better than the national average. The State's 4% annual growth 
rate in 1992 and 1993 ranked second in the nation. The State's 
overall employment picture, which previously had been more dependent 
on natural resource-related industries, has diversified, with 
steady growth in the service and manufacturing sectors. 
    

   
Deterioration of economic conditions could adversely affect both 
tax and other governmental revenues, as well as revenues to be 
used to service various revenue obligations, such as industrial 
development obligations. Such difficulties could adversely affect 
the market value of the Bonds held by the Idaho Advantage Trust 
and thereby adversely affect Unit holders. 
    

   
Further information concerning Idaho risk factors may be obtained 
upon written or telephonic request to the Trustee as described 
in "Information as to Sponsor, Trustee and Evaluator - Who is 
the Trustee?" in Part II of this Prospectus.
    
                        Idaho Tax Status

The assets of the Trust will consist of interest-bearing obligations 
issued by or on behalf of the State of Idaho ("Idaho") or counties, 
municipalities, authorities or political subdivisions thereof 
(the "Idaho Bonds") or by the Commonwealth of Puerto Rico, Guam 
and the United States Virgin Islands (the "Possession Bonds") 
(collectively, the "Bonds").

Neither the Sponsor nor its counsel have independently examined 
the Bonds to be deposited in and held in the Trust. However, although 
no opinion is expressed herein regarding such matters, it is assumed 
that: (i) the Bonds were validly issued, (ii) the Idaho Bonds 
meet the classification and registration requirements of Idaho 
Income Tax Regulation 35.01.01.019, (iii) the interest on the 
Bonds is excludable from gross income for Federal income tax purposes 
and (iv) the interest on the Bonds is exempt from taxation under 
the provisions of the Idaho Income Tax Act (the "Idaho income 
tax"). The opinion set forth below does not address the taxation 
of persons other than full time residents of Idaho.

In the opinion of Chapman and Cutler, Special Counsel to the Fund 
for Idaho tax matters, under existing law as of the date of this 
prospectus and based upon the assumptions set forth above:

(1)     The Trust is not an association taxable as a corporation 
for Idaho income tax purposes and each Unit holder of the Trust 
will be treated as the owner of a pro rata portion of the assets 
held by the Trust and the income of such portion of the Trust 
will be treated as income of the Unit holder for Idaho income 
tax purposes.

(2)     Income on the Bonds which is exempt from the Idaho income 
tax when received by the Trust, and which would be exempt from 
the Idaho income tax if received directly by a Unit holder, will 
retain its status as exempt from such tax when received by the 
Trust and distributed to such Unit holder.

(3)     To the extent that interest income derived from the Trust 
by a Unit holder with respect to Possession Bonds is excludable 
from gross income for Federal income tax purposes pursuant to 
48 U.S.C. Section 745, 48 U.S.C. Section 1423a or 48 U.S.C. Section 
1403, such interest income will not be subject to the Idaho income 
tax.

(4)     In general, each Unit holder will recognize gain or loss 
for Idaho income tax purposes if the Trustee disposes of a Bond 
(whether by redemption, sale or otherwise) or if the Unit holder 
redeems or sells Units of the Trust to the extent that such a 
transaction results in a recognized gain or loss to such Unit 
holder for Federal income tax purposes. However, Idaho income 
tax law may prevent a Unit holder

Page 4 of 12


from taking a recognized loss into account for Idaho income tax 
purposes, under certain circumstances.

(5)     The Idaho income tax does not permit a deduction of interest 
paid on indebtedness incurred or continued to purchase or carry 
Units in the Trust to the extent that interest income related 
to the ownership of Units is exempt from the Idaho income tax.

   
(6)     Any insurance proceeds paid under policies which represent 
maturing interest on defaulted obligations which are excludable 
from gross income for Federal income tax purposes will be excludable 
from the Idaho income tax to the same extent as such interest 
would have been so excludable if paid by the issuer of such Bonds 
held by the Trust 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.
    

Units may be subject to the Idaho estate and transfer tax. Idaho 
has special rules regarding a taxpayer's ability to recognize 
capital losses that apply in certain cases. Unit holders should 
consult their tax advisors regarding these rules.

For information with respect to the Federal income tax status 
and other tax matters, see "What is the Federal Tax Status of 
Unit Holders?" in Part II of this Prospectus.

             Federal and Idaho State Tax-Free Income

The following table shows the approximate marginal taxable yields 
for individuals that are equivalent to tax-exempt yields under 
combined Federal and state taxes, using published Federal tax 
rates and state tax rates scheduled to be in effect in 1995. The 
table incorporates increased tax rates for higher-income taxpayers 
that were included in the Revenue Reconciliation Act of 1993. 
For cases in which more than one state bracket falls within a 
Federal bracket, the higher state bracket is combined with the 
Federal bracket. The combined state and Federal tax rates shown 
reflect the fact that state tax payments are currently deductible 
for Federal tax purposes. The table illustrates what you would 
have to earn on taxable investments to equal the tax-exempt yield 
for your income tax bracket. The taxable equivalent yields may 
be somewhat higher than the equivalent yields indicated in the 
following table for those individuals who have adjusted gross 
incomes in excess of $114,700. The table does not reflect the 
effect of the limitations on itemized deductions and the deduction 
for personal exemptions. They were designed to phase out certain 
benefits of these deductions for higher income taxpayers. These 
limitations, in effect, raise the maximum marginal Federal tax 
rate to approximately 44% for taxpayers filing a joint return 
and entitled to four personal exemptions and to approximately 
41% for taxpayers filing a single return entitled to only one 
personal exemption. These limitations are subject to certain maximums, 
which depend on the number of exemptions claimed and the total 
amount of the taxpayer's itemized deductions. For example, the 
limitation on itemized deductions will not cause a taxpayer to 
lose more than 80% of his allowable itemized deductions, with 
certain exceptions. The following table does not take into account 
the possible effect of the Alternative Minimum Tax.

Neither Cost of Bonds to Sponsor nor Profit or (Loss) to Sponsor 
reflects underwriting profits or losses received or incurred by 
the Sponsor through its participation in underwriting syndicates 
but such amounts reflect the cost of insurance obtained by the 
Sponsor prior to the Initial Date of Deposit for individual Bonds. 
The Offering and Bid Prices of Bonds were determined by Securities 
Evaluation Service, Inc., certain shareholders of which are officers 
of the Sponsor.

(2) All ratings are by Standard & Poor's unless otherwise indicated. 
Such ratings were obtained from a municipal bond information reporting 
service. See "Description of Bond Ratings" in the Information 
Supplement.

   
(3) There is shown under this heading the year in which each issue 
of Bonds initially is redeemable and the redemption price for 
that year or, if currently redeemable, the redemption price in 
effect on the Initial Date of Deposit. Issues of Bonds are redeemable 
at declining prices (but not below par value) in subsequent years 
except for original issue discount Bonds which are redeemable 
at prices based on the issue price plus the amount of original 
issue discount accreted to the redemption date plus, if applicable, 
some premium, the amount of which will decline in subsequent years. 
"S.F." indicates a sinking fund is established with respect to 
an issue of Bonds. In addition, certain Bonds in the portfolio 
may be redeemed in whole or in part other than by operation of 
the stated redemption or sinking fund provisions under certain 
unusual or extraordinary circumstances specified in the instruments 
setting forth the terms and provisions of such Bonds. See "What 
are Certain General Matters Relating to the Trusts?-Risk Factors" 
in Part II of this Prospectus for a discussion of Bond redemptions 
and a description of certain of such unusual or extraordinary 
circumstances under which Bonds may be redeemed. Distributions 
will generally be reduced by the amount of the income which would 
otherwise have been paid with respect to redeemed Bonds and there 
will be distributed to Unit holders the principal amount and any 
premium received on such redemption (except to the extent the 
proceeds of the redeemed Bonds are used to pay for Unit redemptions). 
The estimated current return and the estimated long-term return 
in this event may be affected by such redemptions. For the Federal 
and state tax effect on Unit holders of such redemptions and resultant 
distributions, see "Rights of Unit Holders-What is the Federal 
Tax Status of Unit Holders?" in Part II of this Prospectus and 
"Idaho Tax Status."

REPORT OF INDEPENDENT AUDITORS

   
The Sponsor, Nike Securities L.P., and Unit Holders
The First Trust Combined Series 251
Idaho Advantage Trust, Series 8
    

   
We have audited the accompanying statement of net assets, including 
the portfolio, of Idaho Advantage Trust, Series 8 ("the Trust"), 
included in The First Trust Combined Series 251, as of the opening 
of business on August 9, 1995. This statement of net assets is 
the responsibility of the Trust's Sponsor. Our responsibility 
is to express an opinion on this statement of net assets based 
on our audit.
    

   
We conducted our audit in accordance with generally accepted auditing 
standards. Those standards require that we plan and perform the 
audit to obtain reasonable assurance about whether the statement 
of net assets is free of material misstatement. An audit includes 
examining, on a test basis, evidence supporting the amounts and 
disclosures in the statement of net assets. Our procedures included 
confirmation of the letter of credit held by the Trustee and deposited 
in the Trust on August 9, 1995. An audit also includes assessing 
the accounting principles used and significant estimates made 
by the Sponsor, as well as evaluating the overall presentation 
of the statement of net assets. We believe that our audit of the 
statement of net assets provides a reasonable basis for our opinion. 
    

   
In our opinion, the statement of net assets referred to above 
presents fairly, in all material respects, the financial position 
of Idaho Advantage Trust, Series 8, included in The First Trust 
Combined Series 251, at the opening of business on August 9, 1995 
in conformity with generally accepted accounting principles.

IN THE OPINION OF COUNSEL, INTEREST INCOME TO THE TRUSTS AND TO 
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

What is the First Trust Combined Series?

The First Trust Combined Series is one of a series of investment 
companies created by the Sponsor, 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 set forth in each Part I of this Prospectus 
(such Trusts being collectively referred to herein as the "Fund"). 
This 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, United 
States Trust Company of New York, as Trustee, Securities Evaluation 
Service, Inc., as Evaluator and First Trust Advisors L.P., as 
Portfolio Supervisor. 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 an irrevocable letter of credit issued 
by a financial institution in the amount 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 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." 

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, 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 Trusts as indicated in Part I of this Prospectus 
will be a preference item for purposes of the Alternative Minimum 
Tax. 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 

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.

Trusts from Financial Guaranty Insurance Company ("FGIC") and/or 
AMBAC Indemnity Corporation ("AMBAC") or was obtained directly 
by the Bond issuer, the underwriters, the Sponsor or others prior 
to the Initial Date of Deposit from FGIC, AMBAC 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?" 

On the Initial Date of Deposit, the Sponsor established a percentage 
relationship between the amounts of Bonds in each Trust's portfolio. 
From time to time following the Initial Date of Deposit, the Sponsor, 
pursuant to the Indenture, may deposit additional Bonds in a Trust 
and Units may be continuously offered for sale to the public by 
means of this Prospectus, resulting in a potential increase in 
the outstanding number of Units of a Trust. Any deposit of additional 
Bonds will duplicate, as nearly as is practicable, the original 
proportionate relationship and not the actual proportionate relationship 
on the subsequent date of deposit. The actual proportionate relationship 
may differ from the original proportionate relationship due to 
the sale, redemption or liquidation of any of the Bonds deposited 
in a Trust on the Initial Date of Deposit, or any subsequent date 
of deposit. See "How May Bonds be Removed from the Fund?" Since 
the prices of the underlying Bonds will fluctuate daily, the ratio, 
on a market value basis, will also change daily. The portion of 
Bonds represented by each Unit will not change as a result of 
the deposit of additional Bonds in a Trust.

On the Initial Date of Deposit, each Unit of a Trust represented 
the undivided fractional interest in the Bonds deposited in a 
Trust set forth under "Summary of Essential Information" appearing 
in each Part I of this Prospectus. To the extent that Units of 
a Trust are redeemed, the aggregate value of the Bonds in a Trust 
will be reduced and the undivided fractional interest represented 
by each outstanding Unit of a Trust will increase, although the 
actual interest in such Trust represented by such fraction will 
remain substantially unchanged. Units will remain outstanding 
until redeemed upon tender to the Trustee by any Unit holder, 
which may include the Sponsor, or until the termination of the 
Trust Agreement. However, if additional Units are issued by a 
Trust in connection with the deposit of additional Bonds by the 
Sponsor, the aggregate value of the Bonds in a Trust will be increased 
by amounts allocable to additional Units, and the fractional undivided 
interest represented by each Unit of a Trust will be decreased 
proportionately. See "How May Units be Redeemed?" Each Trust has 
a Mandatory Termination Date as set forth under "Summary of Essential 
Information" appearing in each Part I of this Prospectus.

Risk Factors. An investment in the Trusts should be made with 
an understanding of the risks associated therewith, including, 
among other factors, the inability of the issuer or an insurer 
to pay the principal of or interest on a bond when due, volatile 
interest rates, early call provisions, and changes to the tax 
status of the Bonds. There is, of course, no guarantee that the 
Trusts' objectives will be achieved. See "What are Certain General 
Matters Relating to the Trusts?-Risk Factors."

What are Certain General Matters Relating to the Trusts?

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 and "A-" in the case of an Advantage Trust, 
or the Moody's rating of the Bonds was in no case less than "Baa" 
in the case of an Insured Trust and "A" in the case of an Advantage 
Trust, 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


Page 2

Unit Holders-How May Bonds be Removed from the Fund?" For additional 
risks specific to the individual State Trusts see "Risk Factors" 
appearing in Part I for each State Trust.

Risk Factors

The following paragraphs briefly discuss certain circumstances 
which may adversely affect the ability of issuers of Bonds held 
in the portfolio of a Trust to make payment of principal and interest 
thereon, and which also therefore may adversely affect the ratings 
of such Bonds. With respect to the Insured Trusts, however, because 
of the insurance on the Bonds, such changes should not adversely 
affect either (i) an Insured Trust's receipt of principal and 
interest on any individual Bonds, or (ii) the Units' triple-A 
rating. For economic risks specific to the individual State Trusts, 
see each Part I of this Prospectus and the Information Supplement 
to this Prospectus. Certain of the Trusts may contain some of 
the following types of Bonds:

Discount Bonds are Bonds which 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 Trusts were lower than the current market interest rates 
for newly issued bonds of comparable rating and type. The market 
discount on 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?"

Original Issue Discount Bonds are Bonds which are originally issued 
at a price which represents a discount from the Bonds' stated 
redemption price at maturity. Under current law, the original 
issue discount 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 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?" 
The current value of an original issue 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.

Zero Coupon Bonds represent a certain type of original issue discount 
bonds which 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 Bonds may be subject to greater 
price volatility than conventional bonds. 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.

Premium Bonds are Bonds which 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 such 
bonds are initially higher than the current returns of comparable 
bonds 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. 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?"

General Obligation Bonds are 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, 
both within a particular classification and between classifications, 
depending on numerous factors. 

Healthcare Revenue Bonds are obligations of issuers whose revenues 
are primarily derived from services provided by hospitals or other 
health care facilities, including nursing homes. A health care 
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 financial assistance, 
including Medicare and Medicaid and other similar third-party 
payer programs.

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 interest rates, 
occupancy levels, rental income, mortgage default rates, taxes, 
operating expenses, governmental regulations and the appropriation of 
subsidies.

Water and Sewerage Revenue Bonds are obligations of issuers whose 
revenues are derived from the sale of water and/or sewerage services. 
Such 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.

Electric Utility Revenue Bonds are 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 in obtaining fuel at reasonable 
prices and the effect of energy conservation.

Lease Obligation Revenue Bonds are 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.

Industrial Revenue Bonds ("IRBs") are 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 is dependent 
upon various factors, including the creditworthiness of the corporate 
operator of the project and, if applicable, corporate guarantor, 
revenues generated from the project, expenses associated with 
the project and regulatory and environmental restrictions.

Transportation Facility Revenue Bonds are obligations 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. 

Educational Obligation Revenue Bonds are obligations of issuers 
which govern the operation of, schools, colleges and universities 
and whose revenues are derived mainly from ad valorem taxes, or 
for higher education systems, from tuition, dormitory revenues, 
grants and endowments. General problems relating to school bonds 
include litigation contesting the state constitutionality of financing 
public education in part from ad valorem taxes. General problems 
relating to college and university obligations include the prospect 
of a declining percentage 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.

Resource Recovery Facility Revenue Bonds are obligations which 
are payable from and secured by revenues derived from the operation 
of facilities designed to 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.

Bonds of Issuers Located in the Commonwealth of Puerto Rico. 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.

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 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. See "Portfolio" in each Part 
I of this Prospectus for the earliest scheduled call date and 
the initial redemption price for each Bond. 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 specified in a Bond's 
"Official Statement." 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. 

The contracts to purchase Bonds delivered to the Trustee represent 
an obligation by issuers or dealers to deliver Bonds to the Sponsor 
for deposit in each Trust. Contracts are typically settled and 
the Bonds delivered within a few business days subsequent to the 
Initial Date of Deposit. The percentage of the aggregate principal 
amount of the Bonds of each Trust relating to "when, as and if 
issued" Bonds or other Bonds with delivery dates after the date 
of settlement for a purchase made on the Initial Date of Deposit, 
if any, is indicated in "Portfolio" appearing in each Part I of 
this Prospectus. Interest on "when, as and if issued" and delayed 
delivery Bonds begins accruing to the benefit of Unit holders 
on their dates of delivery. Because "when, as and if issued" Bonds 
have not yet been issued, as of the Initial Date of Deposit each 
Trust is subject to the risk that the issuers thereof might decide 
not to proceed with the offering of such Bonds or that the delivery 
of such Bonds or the delayed delivery Bonds may be delayed. If 
such Bonds, or replacement bonds described


Page 6

below, are not acquired by a Trust or if their delivery is delayed, 
the Estimated Long-Term Return and the Estimated Current Return 
(if applicable) shown in "Special Trust Information" appearing 
in each Part I of this Prospectus for that Trust may be reduced. 

In the event of a failure to deliver any Bond that has been purchased 
for a Trust under a contract, including those Bonds purchased 
on a "when, as and if issued" basis ("Failed Bonds"), the Sponsor 
is authorized under the Indenture to direct the Trustee to acquire 
other specified bonds ("New Bonds") to make up the original corpus 
of such Trust. The New Bonds must be purchased within twenty days 
after delivery of the notice of the failed contract and the purchase 
price (exclusive of accrued interest) may not exceed the amount 
of funds reserved for the purchase of the Failed Bonds. The New 
Bonds (i) must satisfy the criteria previously described for Bonds 
originally included in the Trust, (ii) must have a fixed maturity 
date of at least ten years or, in the case of a shorter term Trust, 
within the range of maturities of the Bonds initially deposited 
in such Trust, but not exceeding the maturity date of the Failed 
Bonds, (iii) must be purchased at a price that results in a yield 
to maturity and in a current return, in each case as of the Initial 
Date of Deposit, at least equal to that of the Failed Bonds, (iv) 
shall not be "when, as and if issued" bonds, (v) with respect 
to an Insured Trust, at the time of acquisition must be insured 
under either the insurance policy obtained by such Insured Trust 
or an insurance policy obtained by the Bond issuer, the underwriters, 
the Sponsor or others and (vi) shall have the benefit of exemption 
from Federal and state taxation on interest to an equal or greater 
extent than the Failed Bonds they replace. Whenever a New Bond 
has been acquired for a Trust, the Trustee shall, within five 
days thereafter, notify all Unit holders of such Trust of the 
acquisition of the New Bond and shall, on the next monthly distribution 
date which is more than 30 days thereafter, make a pro rata distribution 
of the amount, if any, by which the cost to such Trust of the 
Failed Bond exceeded the cost of the New Bond plus accrued interest. 
Once the original corpus of a Trust is acquired, the Trustee will 
have no power to vary the investment of such Trust, i.e., the 
Trustee will have no managerial power to take advantage of market 
variations to improve a Unit holder's investment. 

If New Bonds are not acquired in the event of a failed contract, 
the Sponsor shall refund the sales charge attributable to such 
failed contract to all Unit holders of the affected Trust, and 
the principal and accrued interest (at the coupon rate of the 
relevant Bond to the date the Sponsor is notified of the failure) 
attributable to such failed contract shall be distributed not 
more than thirty days after the determination of such failure 
or at such earlier time as the Trustee in its sole discretion 
deems to be in the interest of the Unit holders of the affected 
Trust. The portion of such interest paid to a Unit holder which 
accrued after the expected date of settlement for purchase of 
his Units will be paid by the Sponsor and accordingly will not 
be treated as tax-exempt income.

To the best knowledge of the Sponsor, there is no litigation pending 
as of the Initial Date of Deposit in respect of any Bonds which 
might reasonably be expected to have a material adverse effect 
upon the Trusts. At any time after the Initial Date of Deposit, 
litigation may be initiated on a variety of grounds with respect 
to Bonds in a Trust. Such litigation 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, except that interest income of certain Bonds in certain 
Trusts may be included as an item of tax preference in calculating 
the Alternative Minimum Tax applicable to both individuals and 
corporations. 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 opening of business on the Initial Date of Deposit, the 
Estimated Current Return (if applicable) and the Estimated Long-Term 
Return under the monthly and semi-annual distribution plans are 
as set forth in "Special Trust Information" appearing in Part 
I of this Prospectus 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


Page 7

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 (if applicable) appearing in Part I of 
this Prospectus 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 takes 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 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 I of this Prospectus 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 
as of the Initial Date of Deposit. 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.

In order to acquire certain of the Bonds contracted for by the 
Sponsor for deposit in a Trust, it may be necessary to pay on 
the settlement dates for delivery of such Bonds amounts covering 
accrued interest on such Bonds which exceed the amounts furnished 
by the Sponsor. The Trustee has agreed to pay for any amounts 
necessary to cover any such excess and will be reimbursed therefor, 
without interest, when funds become available from interest payments 
on the particular Bonds with respect to which such payments have 
been made. Also, since interest on the Bonds in a Trust does not 
begin accruing as tax-exempt interest income to the benefit of 
Unit holders until their respective dates of delivery, the Trustee 
will, in order to obtain for the Unit holders the estimated net 
annual interest income during the first year of each Trust's operations 
as is indicated in the "Special Trust Information" appearing in 
each Part I of this Prospectus, reduce its fee and, to the extent 
necessary, pay expenses of each Trust in an amount equal to the 
amount of interest that would have so accrued on such Bonds between 
the settlement date of units purchased on the Initial Date of 
Deposit and such dates of delivery.

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 is Accrued Interest Treated?

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 the Trust accrues 
such interest daily. Because of this, the 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.

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?"

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 the Trust and distributed to 
Unit holders. Therefore, there


Page 8

will always remain an item of accrued interest that is added to 
the value of the Units. 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 accrued interest from the purchaser 
of his Units. Since the Trustee has the use of the funds 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.

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 I of this Prospectus, the Sponsor will not receive any fees 
in connection with its activities relating to the Trusts. Such 
bookkeeping and administrative charges 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. 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 under "Special Trust Information" in each 
Part I of this Prospectus, 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 Dates of Deposit. While the 
bookkeeping and administrative charges and the supervisory services 
fees may exceed the actual costs of providing such services for 
this Fund, at no time will the total amount received for such 
services rendered to unit investment trusts of which Nike Securities 
L.P. is the Sponsor in any calendar year exceed the aggregate 
cost to the Sponsor or First Trust Advisors L.P. of supplying 
such services in such year.

For each valuation of the Bonds in a Trust after the initial public 
offering period, the Evaluator will receive a fee as indicated 
in the "Special Trust Information" in each Part I of this Prospectus. 
The Trustee pays certain expenses of the Trusts for which it is 
reimbursed by the Trust or Trusts. The Trustee will receive for 
its ordinary recurring services to a Trust a fee as indicated 
in the "Special Trust Information" appearing in each Part I 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." 
Bankers Trust Company issued the irrevocable letter of credit 
for the Fund and provides a line of credit which the Sponsor may 
utilize to acquire securities (which may include certain of the 
Bonds deposited in the Fund). 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. Both 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.

The aggregate cost of the portfolio insurance obtained by an Insured 
Trust is indicated in Note 1 of "Notes to Portfolio" appearing 
in each Part I of this Prospectus. 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. The Trustee will advance the initial premium for the portfolio 
insurance obtained by an Insured Trust and will recover its advancement 
without interest or other costs to such Trust from interest received 
on Bonds in 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 in an Insured Trust 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.


Page 9

Expenses incurred in establishing the Trusts, including costs 
of preparing the registration statement, the trust indenture and 
other closing documents, registering Units with the Securities 
and Exchange Commission and states, the initial audit of each 
Trust portfolio, legal fees, the initial fees and expenses of 
the Trustee and any other out-of-pocket expenses, will be paid 
by the Trusts and amortized over the first five years of such 
Trusts. The following additional charges are or may be incurred 
by a Trust: all expenses (including legal and annual auditing 
expenses) of the Trustee incurred by or 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 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 that the accounts of each Trust shall 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

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 FGIC or AMBAC, or obtained 
by the Bond issuer, the underwriters, the Sponsor or others prior 
to the Initial Date of Deposit directly from one of the insurers 
listed below or other insurers (the "Preinsured Bonds"). The claims-paying 
ability of each of these insurers was rated AAA by Standard & 
Poor's or another nationally recognized rating organizaiton at 
the time the insured Bonds were purchased for the Trust. 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" in Part I of the Prospectus 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 FGIC and/or AMBAC 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, 
FGIC and/or AMBAC 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. Further information concerning 
the individual insurers can be found in the Information Supplement 
to this Prospectus.

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


Page 10

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 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.

The following summary information relating to the listed insurance 
companies has been obtained from publicly available information:

</TABLE>

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 purchase price paid by such Trust will reduce 
payment to Unit holders of the interest and principal required 
to be paid on such Bonds. 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


Page 11

"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.

Chapman and Cutler, Counsel for the Sponsor, has given an opinion 
(with respect to insured Bonds) to the effect that the payment 
of insurance proceeds representing maturing interest on defaulted 
municipal obligations paid by an insurer would be excludable from 
Federal gross income if, and to the same extent as, such interest 
would have been so excludable if paid by the issuer of the defaulted 
obligations 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 obligations, rather than the insurer, will pay debt service 
on the obligations. See "What is the Federal Tax Status of Unit Holders?"

                         PUBLIC OFFERING

How is the Public Offering Price Determined?

Units are offered at the Public Offering Price. During the initial 
offering period, such price is determined by adding to the Evaluator's 
determination of the aggregate offering price of the Bonds in 
each Trust, an amount as indicated in the following table. During 
the initial offering period, the Sponsor's Repurchase Price is 
equal to the Evaluator's determination of the aggregate offering 
price of the Bonds in a Trust. A National Trust consists of The 
First Trust of Insured Municipal Bonds. A State Trust consists 
of The First Trust of Insured Municipal Bonds-Multi-State and/or 
The First Trust Advantage other than an Intermediate, Long Intermediate, 
Short Intermediate or Discount Trust. An Intermediate, Long Intermediate, 
Short Intermediate or Discount Trust consists of trusts so designated.

_____________________
(1)     The Public Offering Price includes a proportionate share 
of interest accrued but unpaid on the Bonds after the First Settlement 
Date to the date of settlement. See "General Trust Information-How 
is Accrued Interest Treated?"

The applicable sales charge is reduced by a discount as indicated 
in "Summary of Essential Information" in each Part 1 of this Prospectus 
(except for sales made pursuant to a "wrap fee account" or similar 
arrangements as set forth below) for volume purchases.

The Public Offering Price of Units for secondary market purchases 
will be determined by adding to the Evaluator's determination 
of the aggregate bid price of the Bonds in a Trust, the appropriate 
sales charge determined in accordance with the schedule set forth 
in the Information Supplement to this Prospectus, 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.


Page 12

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. The 
purchaser must inform the Underwriter or dealer of any such combined 
purchase prior to the sale in order to obtain the indicated discount. 
In addition, 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 persons) of 
the Sponsor and the Underwriters and their subsidiaries, the sales 
charge is reduced by 2.0% of the Public Offering Price for purchases 
of Units during the primary and secondary public offering periods.

Any such reduced sales charge shall be the responsibility of the 
selling Underwriter or dealer except that with respect to purchases 
of Units of $500,000 or more, the Sponsor will reimburse the selling 
Underwriter or dealer in an amount equal to $2.50 per Unit (in 
the case of a Discount Trust, .25% of the Public Offering Price). 
The reduced sales charge structure will apply on all purchases 
of Units in a Trust by the same person on any one day from any 
one Underwriter or 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 such 
Underwriter or 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.

Units may be purchased in the primary or secondary market at the 
Public Offering Price less the concession the Sponsor typically 
allows to dealers and other selling agents for purchases (see 
"Public Offering-How are Units Distributed?") by investors who 
purchase Units through registered investment advisers, certified 
financial planners and registered broker-dealers who in each case 
either charge periodic fees for financial planning, investment 
advisory or asset management services, or provide such services 
in connection with the establishment of an investment account 
for which a comprehensive "wrap fee" charge is imposed.

On the Initial Date of Deposit, the Public Offering Price is as 
indicated in the "Summary of Essential Information" appearing 
in each Part I of this Prospectus. The Public Offering Price during 
the initial offering period will vary from day-to-day due to fluctuations 
in the amount of interest accrued but unpaid on Bonds in each 
Trust of the Fund and/or fluctuations in the prices of the underlying 
Bonds.

The aggregate price of the Bonds in each Trust is determined by 
the evaluator (the "Evaluator"), on the basis of bid prices or 
offering prices as is appropriate, (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 FGIC and/or AMBAC to meet its commitments under the 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.


Page 13

During the initial public offering period, a determination of 
the aggregate price of the Bonds in a Trust is made by the Evaluator 
on an offering 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 made subsequent to the last preceding determination. 
For purposes of such determinations, the close of trading on the 
New York Stock Exchange is 4:00 p.m. eastern standard time. For 
secondary market purposes, the Evaluator will be requested to 
make such a determination, 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 days following the order 
for purchase (the date of settlement), payment may be made prior 
thereto. A person will become owner of 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 "Rights of Unit 
Holders-How May Units Be Redeemed?" for information regarding 
the ability to redeem Units ordered for purchase.

How are Units Distributed?

During the initial offering period, until the primary distribution 
of the Units offered by this Prospectus is completed, Units will 
be offered to the public at the Public Offering Price, computed 
as described above, by the Underwriters, including the Sponsor 
(see "What are the Underwriting Concessions?") and through dealers 
and other selling agents. The initial offering period may be up 
to approximately 360 days. During this period, the Sponsor may 
deposit additional Bonds in each Trust and create additional Units. 
Upon completion of the initial offering, 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 initially will be made to 
dealers and other selling agents at prices which represent a concession 
or agency commission of $32 per Unit for a National Trust and 
certain State Trusts, $33 per Unit for other State Trusts, $28 
per Unit for a Long Intermediate Trust, $25 per Unit for an Intermediate 
Trust and $18 per Unit for a Short Intermediate Trust. However, 
resales of Units of a Trust by such dealers and other selling 
agents to the public will be made at the Public Offering Price 
described in the 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 
Trusts 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 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. Any broker/dealer 
or bank will receive additional concessions for purchases made 
from the Sponsor on the Initial Date of Deposit resulting in total 
concessions as contained in the following table:

_____________________
(1)     The applicable concession will be allotted to broker/dealers 
or banks who purchase Units from the Sponsor only on the Initial 
Date of Deposit of a given Trust. 

What are the Sponsor's Profits?

The Underwriters of each Trust, including the Sponsor, will receive 
a gross sales commission equal to 4.9% of the Public Offering 
Price of the Units for a National Trust and certain State Trusts 
(5.152% of the net amount invested), 5.5% of the Public Offering 
Price of the Units for other State Trusts (5.820% of the net amount 
invested), 4.4% of the Public Offering Price of the Units for 
a Long Intermediate Trust (4.603% of the net amount invested), 
3.9% of the Public Offering Price of the Units for an Intermediate 
Trust (4.058% of the net amount invested) and 3.0% of the Public 
Offering Price of the Units for a Short Intermediate Trust (3.093% 
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?" See "What are the Underwriting 
Concessions?" for information regarding the receipt of the excess 
gross sales commissions by the Sponsor from the other Underwriters 
and additional concessions available to Underwriters, dealers 
and other selling agents. In addition, the Sponsor and the other 
Underwriters of each Trust may be considered to have realized 
a profit or the Sponsor may be considered to have sustained a 
loss, as the case may be for each Trust, in the amount of any 
difference between the cost of the Bonds to each Trust (which 
is based on the Evaluator's determination of the aggregate offering 
price of the underlying Bonds of such Trust on the Initial Date 
of Deposit as well as subsequent deposits) and the cost of such 
Bonds of such Trust to the Sponsor (including the cost of insurance 
obtained by the Sponsor prior to the Initial Date of Deposit for 
individual Bonds). See "What are the Underwriting Concessions?" 
and Note 1 of "Notes to Portfolio" appearing in each Part I of 
this Prospectus. Such profits or losses may be realized or sustained 
by the Sponsor and the other Underwriters with respect to Bonds 
which were acquired by the Sponsor from underwriting syndicates 
of which it and the other Underwriters were members. During the 
initial offering period, the Underwriters also may realize profits 
or sustain losses from the sale of Units to other Underwriters 
or as a result of fluctuations after the Initial Date of Deposit 
or subsequent dates of deposit in the offering prices of the Bonds 
and hence in the Public Offering Price received by the Underwriters.

The Sponsor has not participated as sole underwriter or manager 
or member of underwriting syndicates from which any of the Bonds 
in the Fund were acquired. An underwriter or underwriting syndicate 
purchases bonds from the issuer on a negotiated or competitive 
bid basis as principal with the motive of marketing such bonds 
to investors at a profit.

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 sales charge of 5.8% for a National or Discount 
Trust, 5.8% for a State 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. 


What are the Underwriting Concessions?

The Agreement Among Underwriters provides that a public offering 
of the Units of each Trust will be made at the Public Offering 
Price described in the Prospectus. Units may also be sold to or 
through dealers and


Page 15

other selling agents during the initial offering period and in 
the secondary market at prices representing a concession or agency 
commission as described in "Public Offering-How are Units Distributed?"

The Sponsor will receive from the Underwriters the excess over 
the gross sales commission contained in the following table:

</TABLE>


In addition to any other benefits that the Underwriters may realize 
from the sale of the Units of a Trust, the Agreement Among Underwriters 
provides that the Sponsor will share with the other Underwriters 
50% of the net gain, if any, represented by the difference between 
the Sponsor's cost of the Bonds in connection with their acquisition 
(including the cost of insurance obtained by the Sponsor prior 
to the Initial Date of Deposit for individual Bonds and including 
the effects of portfolio hedging gains and losses and portfolio 
hedging transaction costs) and the Aggregate Offering Price thereof 
on the Initial Date of Deposit, less a charge for acquiring the 
Bonds in the portfolio and for the Sponsor maintaining a secondary 
market for the Units. Furthermore, any underwriter that sells 
a total of 1,000 Units or more of any National Trust will receive 
an additional $2.00 per Unit sold. See "Public Offering-What are 
the Sponsor's Profits?" and Note 1 of "Notes to Portfolio" in 
each Part I of this Prospectus. McLaughlin, Piven, Vogel Securities, 
Inc. ("MPV") and Nike Securities L.P. have an agreement under 
which MPV will receive from Nike Securities L.P. reimbursement 
for certain costs and further compensation, in addition to that 
described above, based on the number of Units it underwrites or 
otherwise sells and on the total Units of Nike Securities L.P. 
products sold.

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 reallow 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.

Will There be a Secondary Market?

After the initial offering period, 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 interest accrued to 
the date of settlement. All expenses incurred in maintaining a 
secondary market, other than the fees of the Evaluator, the other 
expenses of the Trust and the costs of the Trustee in transferring 
and recording the ownership of Units, will be borne by the Sponsor. 
The Sponsor may, at any time, 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.


Page 16

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 this Fund, the purchase price per unit of such bond funds 
will depend primarily on the value of the securities in the portfolio 
of the fund.

                     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 three 
days following such order or shortly thereafter. Certificates 
to be redeemed or transferred must be surrendered to the Trustee 
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?

Interest from each Trust after deduction of amounts sufficient 
to reimburse the Trustee, without interest, for any amounts advanced 
and paid to FGIC and/or AMBAC or to the Sponsor as the Unit holder 
of record as of the First Settlement Date will be distributed 
on or shortly after the last day of each month on a pro rata basis 
to Unit holders of record as of the preceding Record Date who 
are entitled to distributions at that time under the plan of distribution 
chosen. All distributions for a Trust will be net of applicable 
expenses for such Trust.

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. See 
"Special Trust Information" appearing in each Part I of this Prospectus.

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. All Unit holders will 
receive the first distribution of interest regardless of the plan 
of distribution chosen and all Unit holders will receive such 
distributions, if any, from the Principal Account as are made 
as of the Record Dates for monthly distributions. PURCHASERS OF 
UNITS WHO DESIRE TO RECEIVE DISTRIBUTIONS ON A SEMI-ANNUAL BASIS 
MAY ELECT TO DO SO AT THE TIME OF PURCHASE DURING THE INITIAL 
PUBLIC OFFERING PERIOD. THOSE NOT SO INDICATING WILL BE DEEMED 
TO HAVE CHOSEN THE MONTHLY DISTRIBUTION PLAN.


Page 17

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 or shortly after the last day of each month. 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 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 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


Page 18

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 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 is the 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 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. (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.) It should be noted that under 
provisions of the Revenue Reconciliation Act of 1993 (the "Tax 
Act") that subject accretion of market discount on tax-exempt 
bonds to taxation as ordinary income, gain realized on the sale 
or redemption of Bonds by the Trustee or of Units by a Unit holder 
that would have been treated as capital gain under prior law is 
treated as ordinary income to the extent it is attributable to 
accretion of market discount. Market discount can arise based 
on the price a Trust pays for Bonds or the price a Unit holder 
pays for his Units. 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 the Units, unless a Unit holder elects to 
include market


Page 19

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.

In the opinion of Chapman and Cutler, Counsel for the Sponsor, 
under existing law:

(1)     the Trusts are not associations taxable as corporations for 
Federal income tax purposes. Tax-exempt interest received by each 
of the Trusts on Bonds deposited therein will retain its status 
as tax-exempt interest, for Federal income tax purposes, when 
distributed to a Unit holder except that (i) interest income on 
certain Bonds in certain Trusts may be included as an item of 
tax preference in calculating the Alternative Minimum Tax applicable 
to both individuals and corporations (see "Portfolio" for each 
Trust to determine whether the Trust contains Bonds that generate 
this type of interest income) and (ii) the alternative minimum 
tax and the environmental tax (the "Superfund Tax") applicable 
to corporate Unit holders may, in certain circumstances, include 
in the amount on which such tax is calculated, 75% of the interest 
income received by the Trust. See "Certain Tax Matters Applicable 
to Corporate Unit Holders;"

(2)     exemption of interest and accrued original issue discount 
on any Bonds for Federal income tax purposes does not necessarily 
result in tax exemption under the laws of the several states as 
such laws vary with respect to the taxation of such securities 
and in many states all or a part of such interest and accrued 
original issue discount may be subject to tax;

(3)     each Unit holder of a Trust is considered to be the owner 
of a pro rata portion of such Trust under subpart E, subchapter 
J of chapter 1 of the Internal Revenue Code of 1986 (hereinafter 
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, if any, on Bonds delivered 
after the date the Unit holders pay for their Units 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 his basis for 
his fractional interest in the asset disposed of. In the case 
of a Unit holder who purchases his Units, such basis is determined 
by apportioning the tax basis for the Units among each of the 
Trust assets ratably according to value as of the date of acquisition 
of the Units. The basis of each Unit and of each Bond which was 
issued with original issue discount must be increased by the amount 
of accrued original issue discount and the basis of each Unit 
and of each Bond which was purchased by a Trust at a premium must 
be reduced by the annual amortization of Bond premium. The tax 
cost reduction requirements of said 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

(4)     any insurance proceeds which represent maturing interest 
on defaulted obligations 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 by the issuer of 
the defaulted obligations 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 obligations, rather than the insurer, will pay 
debt service on the obligations. 

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). 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


Page 20

to ownership of Units. Investors with questions regarding these 
issues should consult with their tax advisers.

In the case of certain of the Bonds in a Trust, the opinions of 
bond counsel indicate that interest on such securities received 
by a "substantial user" of the facilities being financed with 
the proceeds of these securities, or persons related thereto, 
for periods while such securities are held by such a user or related 
person, will not be excludable from Federal gross income, although 
interest on such securities received by others would be excludable 
from Federal gross income. "Substantial user" and "related person" 
are defined under 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 Social Security 
benefits are includible in gross income in an amount equal to 
the lesser of (1) 50% of the Social Security benefits received 
or (2) 50% of the excess of "modified adjusted gross income" plus 
50% of the Social Security benefits received over the appropriate 
"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 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. See "Portfolio" in Part 
I of this Prospectus for each Trust to determine whether the Trust 
includes any such private activity bonds issued on or after that 
date. SEE "PORTFOLIO" IN PART I OF THIS PROSPECTUS FOR EACH TRUST 
TO DETERMINE WHETHER THE TRUST INCLUDES ANY SUCH PRIVATE ACTIVITY 
BONDS ISSUED ON OR AFTER THAT DATE.

All taxpayers are presently required to disclose to the Internal 
Revenue Service the amount of tax-exempt interest earned during the year.

Certain Tax Matters Applicable to Corporate Unit Holders. Present 
Federal income tax law also provides for an alternative minimum 
tax for corporations levied at a rate of 20% of alternative minimum 
taxable income. The alternative minimum tax and the environmental 
tax (the "Superfund Tax") depend 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 of a corporation (excluding 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). Although tax-exempt interest received by the Trusts 
on Bonds deposited therein will not be included in the gross income 
of corporations for Federal income tax purposes, "adjusted current 
earnings" includes all tax-exempt interest, including interest 
on all Bonds in the Trusts. 

Unit holders are urged to consult their own 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.

In the opinion of Carter, Ledyard & Milburn, Special Counsel to 
the Fund for New York tax matters, under the existing income tax 
laws of the State and City of New York, 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.

For information with respect to exemption from state or other 
local taxes, see the sections in the Prospectus pertaining to 
each Trust.

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.

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.

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, except that as regards 
Units received after the close of trading on the New York Stock 
Exchange, the date of tender is the next day on which 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.

Accrued interest to the settlement date paid on redemption shall 
be withdrawn from the Interest Account of the 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 (as well as the secondary market 
Public Offering Price) will be determined on the basis of the 
bid price of the Bonds in the Trust as of the close of trading 
on the New York Stock Exchange


Page 22

on the date any such determination is made. On the Initial Date 
of Deposit the Public Offering Price per Unit (which is based 
on the offering prices of the Bonds in the Trust and includes 
the sales charge) exceeded the Unit value at which Units could 
have been redeemed (based upon the current bid prices of the Bonds 
in such Trust) by the amount shown under "Summary of Essential 
Information" in each Part I of this Prospectus. 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) 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 the 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 "General Trust Information-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, it may purchase 
such Units by notifying the Trustee before 12:00 p.m. eastern 
standard 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 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


Page 23

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 are Certain General Matters Relating to the Trusts?" for 
Failed Bonds, the acquisition by a Trust of any securities other 
than the Bonds initially deposited is prohibited.

it may be consolidated, or any corporation resulting from any 
merger or consolidation to which a Trustee shall be a party, shall 
be the successor Trustee. The Trustee must be a banking corporation 
organized under the laws of the United States or any State and

Limitations on Liabilities of Sponsor and Trustee

The Sponsor and the Trustee shall be under no liability to Unit 
holders 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 Trustee of any of the Bonds. In the 
event of the failure of the Sponsor to act under the Indenture, 
the Trustee may act thereunder and shall not be liable for any 
action taken by it in good faith under the Indenture.

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 authority having jurisdiction. In addition, the 
Indenture contains other 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 Trustee to be reasonable and not exceeding amounts prescribed 
by the Securities and Exchange Commission, or (b) terminate the 
Indenture and liquidate the Trusts as provided herein, or (c) 
continue to act as Trustee without terminating the Indenture.

Who is the Evaluator?

The Evaluator is Securities Evaluation Service, Inc., 531 East 
Roosevelt Road, Suite 200, Wheaton, Illinois 60187. The Evaluator 
may resign or may be removed by the Sponsor or the Trustee, in 
which event the Sponsor and the Trustee are to use their best 
efforts to appoint a satisfactory successor. Such resignation 
or removal shall become 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 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.


Page 25

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 deposited in the Trust 
during the primary offering period 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 
December 31, 2044. 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.

                     INFORMATION SUPPLEMENT
   
This Information Supplement provides additional information concerning 
the structure, operations and risks of a First Trust Combined 
Series Trust not found in the prospectuses for the Trusts. This 
Information Supplement is not a prospectus and does not include 
all of the information that a prospective investor should consider 
before investing in a Trust. This Information Supplement should 
be read in conjunction with the prospectus for the Trust in which 
an investor is considering investing ("Prospectus"). Copies of 
the Prospectus can be obtained by calling or writing the Trustee 
at the telephone number and address indicated in Part II of the 
Prospectus. This Information Supplement has been created to supplement 
information contained in the Prospectus.
    

The Objectives of the Fund are conservation of capital through 
investment in portfolios of tax-exempt bonds and income exempt, with 
certain exceptions, from Federal and applicable state and local 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.


   
This Information Supplement is dated August 9 1995. Capitalized 
terms have been defined in the Prospectus.

General Risk Disclosure

Discount Bonds. 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 Trusts were lower than the current 
market interest rates for newly issued bonds of comparable rating 
and type. If such interest rates for newly issued comparable bonds 
increase, the market discount of previously issued bonds will 
become greater, and if such interest rates for newly issued comparable 
bonds decline, the market discount of previously issued bonds 
will be reduced, other things being equal. Investors should also 
note that the value of bonds purchased at a market discount will 
increase in value faster than bonds purchased at a market premium 
if interest rates decrease. Conversely, if interest rates increase, 
the value of bonds purchased at a market discount will decrease 
faster than bonds purchased at a market premium. In addition, 
if interest rates rise, the prepayment risk of higher yielding, 
premium bonds and the prepayment benefit for lower yielding, discount 
bonds will be reduced. 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


Page 1

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?" Market discount attributable to interest changes 
does not indicate a lack of market confidence in the issue. Neither 
the Sponsor nor the Trustee shall be liable in any way for any 
default, failure or defect in any of the Bonds.

Original Issue Discount Bonds. 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?" 
The current value of an original issue 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.

Zero Coupon Bonds. Certain of the original issue discount bonds 
may be Zero Coupon Bonds (including bonds known as multiplier 
bonds, money multiplier bonds, 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 Bonds may be subject to more price volatility than 
conventional bonds. While some types of Zero Coupon Bonds, such 
as multipliers and capital appreciation bonds, define par as the 
initial offering price rather than the maturity value, they share 
the basic Zero Coupon Bond features of (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, 
i.e., a bond's provision for redemption at only a modest premium 
over the accreted value of the bond.

Premium Bonds. 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. If such interest rates for newly issued and otherwise comparable 
bonds decrease, the market premium of previously issued bonds 
will be increased, and if such interest rates for newly issued 
comparable bonds increase, the market premium of previously issued 
bonds will be reduced, other things being equal. 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. Redemption pursuant 
to call provisions generally will, and redemption pursuant to 
sinking fund provisions may, occur at times when the redeemed 
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 the event 
that all the Bonds in the portfolio other than the Zero Coupon 
Bonds are called or redeemed in order to pay expenses


Page 2

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?" 
See "Portfolio" for each Trust for the earliest scheduled call 
date and the initial redemption price for each Bond. 

General Obligation Bonds. 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. 

Healthcare Revenue Bonds. Certain of the Bonds in the Trusts may 
be health care revenue bonds. Ratings of bonds issued for health 
care facilities are sometimes based on feasibility studies that 
contain projections of occupancy levels, revenues and expenses. 
A facility's gross receipts and net income available for debt 
service may be affected by future events and conditions including 
among other things, demand for services, the ability of the facility 
to provide the services required, physicians' confidence in the 
facility, management capabilities, competition with other hospitals, 
efforts by insurers and governmental agencies to limit rates, 
legislation establishing state rate-setting agencies, expenses, 
government regulation, the cost and possible unavailability of 
malpractice insurance and the termination or restriction of governmental 
financial assistance, including that associated with Medicare, 
Medicaid and other similar third party payor programs. Pursuant 
to recent Federal legislation, Medicare reimbursements are currently 
calculated on a prospective basis utilizing a single nationwide 
schedule of rates. Prior to such legislation Medicare reimbursements 
were based on the actual costs incurred by the health facility. 
The current legislation may adversely affect reimbursements to 
hospitals and other facilities for services provided under the 
Medicare program. 

Single Family Mortgage Revenue Bonds. Certain of the Bonds in 
the Trusts may be single family mortgage revenue bonds, which 
are issued for the purpose of acquiring from originating financial 
institutions notes secured by mortgages on residences located 
within the issuer's boundaries and owned by persons of low or 
moderate income. Mortgage loans are generally partially or completely 
prepaid prior to their final maturities as a result of events 
such as sale of the mortgaged premises, default, condemnation 
or casualty loss. Because these Bonds are subject to extraordinary 
mandatory redemption in whole or in part from such prepayments 
of mortgage loans, a substantial portion of such Bonds will probably 
be redeemed prior to their scheduled maturities or even prior 
to their ordinary call dates. The redemption price of such issues 
may be more or less than the offering price of such Bonds. Extraordinary 
mandatory redemption without premium could also result from the 
failure of the originating financial institutions to make mortgage 
loans in sufficient amounts within a specified time period or, 
in some cases, from the sale by the Bond issuer of the mortgage 
loans. Failure of the originating financial institutions to make 
mortgage loans would be due principally to the interest rates 
on mortgage loans funded from other sources becoming competitive 
with the interest rates on the mortgage loans funded with the 
proceeds of the single family mortgage revenue bonds. Additionally, 
unusually high rates of default on the underlying mortgage loans 
may reduce revenues available for the payment of principal of 
or interest on such mortgage revenue bonds. Single family mortgage 
revenue bonds issued after December 31, 1980 were issued under 
Section 103A of the Internal Revenue Code, which Section contains 
certain ongoing requirements relating to the use of the proceeds 
of such Bonds in order for the interest on such Bonds to retain 
its tax-exempt status. In each case, the issuer of the Bonds has 
covenanted to comply with applicable ongoing requirements and 
bond counsel to such issuer has issued an opinion that the interest 
on the Bonds is exempt from Federal income tax under existing 
laws and regulations. There can be no assurances that the ongoing 
requirements will be met. The failure to meet these


Page 3

requirements could cause the interest on the Bonds to become taxable, 
possibly retroactively from the date of issuance. 

Multi-Family Mortgage Revenue Bonds. Certain of the Bonds in the 
Trusts may be obligations of issuers whose revenues are primarily 
derived from mortgage loans to housing projects for low to moderate 
income families. The ability of such issuers to make debt service 
payments will be affected by events and conditions affecting financed 
projects, including, among other things, the achievement and maintenance 
of sufficient occupancy levels and adequate rental income, increases 
in taxes, employment and income conditions prevailing in local 
labor markets, utility costs and other operating expenses, the 
managerial ability of project managers, changes in laws and governmental 
regulations, the appropriation of subsidies and social and economic 
trends affecting the localities in which the projects are located. 
The occupancy of housing projects may be adversely affected by 
high rent levels and income limitations imposed under Federal 
and state programs. Like single family mortgage revenue bonds, 
multi-family mortgage revenue bonds are subject to redemption 
and call features, including extraordinary mandatory redemption 
features, upon prepayment, sale or non-origination of mortgage 
loans as well as upon the occurrence of other events. Certain 
issuers of single or multi-family housing bonds have considered 
various ways to redeem bonds they have issued prior to the stated 
first redemption dates for such bonds. In one situation the New 
York City Housing Development Corporation, in reliance on its 
interpretation of certain language in the indenture under which 
one of its bond issues was created, redeemed all of such issue 
at par in spite of the fact that such indenture provided that 
the first optional redemption was to include a premium over par 
and could not occur prior to 1992. In connection with the housing 
Bonds held by a Trust, the Sponsor has not had any direct communications 
with any of the issuers thereof, but at the Initial Date of Deposit 
it is not aware that any of the respective issuers of such Bonds 
are actively considering the redemption of such Bonds prior to 
their respective stated initial call dates. However, there can 
be no assurance that an issuer of a Bond in a Trust will not attempt 
to so redeem a Bond in a Trust.

Water and Sewerage Revenue Bonds. 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. All of such issuers have been experiencing certain 
of these problems in varying degrees. 

Electric Utility Revenue Bonds. 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 on an approved asset base. 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, 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. 
All of such issuers have been experiencing certain of these problems 
in varying degrees. In addition, Federal, state and municipal 
governmental authorities may from time to time review existing 
and impose additional regulations governing the licensing, construction 
and operation of nuclear power plants, which may adversely affect 
the ability of the issuers of such Bonds to make payments of principal 
and/or interest on such Bonds. 

Lease Obligation Revenue Bonds. Certain of the Bonds in the Trusts 
may be lease obligations issued for the most part 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


Page 4

(schools, administrative offices, convention centers and prisons, 
for example) or the purchase of equipment (police cars and computer 
systems, for example) that will be used by a state or local government 
(the "lessee"). Thus, 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 the 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. These obligations are also subject to construction 
and abatement risk in many states-rental obligations cease in 
the event that delays in building, damage, destruction or condemnation 
of the project prevents its use by the lessee. In these cases, 
insurance provisions designed to alleviate this risk become important 
credit factors. In the event of default by the lessee government, 
there may be significant legal and/or practical difficulties involved 
in the re-letting or sale of the project. Some of these issues, 
particularly those for equipment purchase, contain the so-called 
"substitution safeguard", which bars the lessee government, in 
the event it defaults on its rental payments, from the purchase 
or use of similar equipment for a certain period of time. This 
safeguard is designed to insure that the lessee government will 
appropriate, even though it is not legally obligated to do so, 
but its legality remains untested in most, if not all, states. 

Industrial Revenue Bonds. Certain of the Bonds in the Trusts may 
be industrial revenue bonds ("IRBs"), including pollution control 
revenue bonds, which are tax-exempt securities issued by states, 
municipalities, public authorities or similar entities to finance 
the cost of acquiring, constructing or improving various industrial 
projects. These projects are usually operated by corporate entities. 
Issuers are obligated only to pay amounts due on the IRBs to the 
extent that funds are available from the unexpended proceeds of 
the IRBs or receipts or revenues of the issuer under an arrangement 
between the issuer and the corporate operator of a project. The 
arrangement may be in the form of a lease, installment sale agreement, 
conditional sale agreement or loan agreement, but in each case 
the payments to the issuer are designed to be sufficient to meet 
the payments of amounts due on the IRBs. Regardless of the structure, 
payment of IRBs is solely dependent upon the creditworthiness 
of the corporate operator of the project or corporate guarantor. 
Corporate operators or guarantors may be affected by many factors 
which may have an adverse impact on the credit quality of the 
particular company or industry. These include cyclicality of revenues 
and earnings, regulatory and environmental restrictions, litigation 
resulting from accidents or environmentally-caused illnesses, 
extensive competition and financial deterioration resulting from 
a complete restructuring pursuant to a leveraged buy-out, takeover 
or otherwise. Such a restructuring may result in the operator 
of a project becoming highly leveraged which may impact on such 
operator's creditworthiness, which in turn would have an adverse 
impact on the rating and/or market value of such Bonds. Further, 
the possibility of such a restructuring may have an adverse impact 
on the market for and consequently the value of such Bonds, even 
though no actual takeover or other action is ever contemplated 
or affected. The IRBs in a Trust may be subject to special or 
extraordinary redemption provisions which may provide for redemption 
at par or, with respect to original issue discount bonds, at issue 
price plus the amount of original issue discount accreted to the 
redemption date plus, if applicable, a premium. The Sponsor cannot 
predict the causes or likelihood of the redemption of IRBs or 
other Bonds in the Trusts prior to the stated maturity of such Bonds. 

Transportation Facility Revenue Bonds. 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 major portion of an airport's gross operating 
income is generally derived from fees received from signatory 
airlines pursuant to use agreements which consist of annual payments 
for leases, occupancy of certain terminal space and service fees. 
Airport operating income may therefore be affected by the ability 
of the airlines to meet their obligations under the use agreements. 
The air transport industry is experiencing significant variations 
in earnings and traffic, due to increased competition, excess 
capacity, increased costs, deregulation, traffic constraints and 
other factors, and several airlines are experiencing severe financial 
difficulties. The Sponsor cannot predict what effect these industry 
conditions may have on airport revenues which are dependent for 
payment on the financial condition of the airlines and their usage 
of the particular airport facility. Similarly, payment on Bonds

Page 5


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. 

Educational Obligation Revenue Bonds. Certain of the Bonds in 
the Trusts may be obligations of issuers which are, or which govern 
the operation of, schools, colleges and universities and whose 
revenues are derived mainly from ad valorem taxes, or for higher 
education systems, from tuition, dormitory revenues, grants and 
endowments. General problems relating to school bonds include 
litigation contesting the state constitutionality of financing 
public education in part from ad valorem taxes, thereby creating 
a disparity in educational funds available to schools in wealthy 
areas and schools in poor areas. Litigation or legislation on 
this issue may affect the sources of funds available for the payment 
of school bonds in the Trusts. 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. All of such issuers have been experiencing 
certain of these problems in varying degrees.

Resource Recovery Facility Revenue Bonds. 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 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. The Sponsor cannot predict the 
causes or likelihood of the redemption of resource recovery bonds 
in the Trusts prior to the stated maturity of the Bonds.

Bonds of Issuers Located in the Commonwealth of Puerto Rico. Certain 
Trusts of the Fund 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


Page 6

of such limitation, it is expected that the limitation of Section 
936 credits would have a negative impact on Puerto Rico's economy.

Aid for Puerto Rico's economy has traditionally depended heavily 
on Federal programs, and current Federal budgetary policies suggest 
that an expansion of aid to Puerto Rico is unlikely. An adverse 
effect on the Puerto Rican economy could result from other U.S. 
policies, including a reduction of tax benefits for distilled 
products, further reduction in transfer payment programs such 
as food stamps, curtailment of military spending and policies 
which could lead to a stronger dollar.

In a plebiscite held in November 1993, the Puerto Rican electorate 
chose to continue Puerto Rico's Commonwealth status. Previously 
proposed legislation, which was not enacted, would have preserved 
the federal tax exempt status of the outstanding debts of Puerto 
Rico and its public corporations regardless of the outcome of 
the referendum, to the extent that similar obligations issued 
by the states are so treated and subject to the provisions of 
the Internal Revenue Code currently in effect. There can be no 
assurance that any pending or future legislation finally enacted 
will include the same or a similar protection against loss of 
tax exemption. The November 1993 plebiscite can be expected to 
have both direct and indirect consequences on such matters as 
the basic characteristics of future Puerto Rico debt obligations, 
the markets for these obligations, and the types, levels and quality 
of revenue sources pledged for the payment of existing and future 
debt obligations. Such possible consequences include, without 
limitation, legislative proposals seeking restoration of the status 
of Section 936 benefits otherwise subject to the limitations discussed 
above. However, no assessment can be made at this time of the 
economic and other effects of a change in federal laws affecting 
Puerto Rico as a result of the November 1993 plebiscite.

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.

Insurance on the Bonds

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


Page 7

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 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

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.

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 $1,988,000,000 (unaudited) 
and statutory capital of approximately $1,148,000,000 (unaudited) 
as of March 31, 1994. 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.

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 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.

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

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


Page 11

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 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, 1992 and 1991, CapMAC had statutory capital 
and surplus of approximately $148 million and $232 million, respectively, 
and had not incurred any debt obligations. On June 26, 1992, CapMAC 
made a special distribution (the "Distribution") to Holdings in 
connection with the Sale in an aggregate amount that caused the 
total of CapMAC's statutory capital and surplus to decline to 
approximately $150 million. Holdings applied substantially all 
of the proceeds of the Distribution to repay debt owed to Citicorp 


Page 12

that was incurred in connection with the capitalization of CapMAC. 
As of June 30, 1992, CapMAC had statutory capital and surplus 
of approximately $150 million and had not incurred any debt obligations. 
In addition, on December 31, 1992 CapMAC had a statutory contingency 
reserve of approximately $15 million, which is also available 
to cover claims under surety bonds issued by CapMAC. Article 69 
of the New York State Insurance Law requires that CapMAC establishes 
and maintains the contingency reserve.

In addition to its capital (including contingency reserve) and 
other reinsurance available to pay claims under its surety bonds, 
on June 25, 1992, CapMAC entered into a Stop Loss Reinsurance 
Agreement (the "Stop Loss Agreement") with Winterthur Swiss Insurance 
Company (the "Reinsurer"), which is rated AAA by Standard & Poor's 
and Aaa by Moody's, pursuant to which the Reinsurer will be required 
to pay any losses incurred by CapMAC during the term of the Stop 
Loss Agreement on the surety bonds covered under the Stop Loss 
Agreement in excess of a specified amount of losses incurred by 
CapMAC under such surety bonds (such specified amount initially 
being $100 million and increasing annually by an amount equal 
to 66 2/3% of the increase in CapMAC's statutory capital and surplus) 
up to an aggregate limit payable under the Stop Loss Agreement 
of $50 million. The Stop Loss Agreement has an initial term of 
seven years, is extendable for one-year periods and is subject 
to early termination upon the occurrence of certain events.

CapMAC also has available a $100,000,000 standby corporate liquidity 
facility (the "Liquidity Facility") provided by a syndicate of 
banks rated A1+/P1 by Standard & Poor's and Moody's, respectively, 
having a term of 360 days. Under the Liquidity Facility CapMAC 
will be able, subject to satisfying certain conditions, to borrow 
funds from time to time in order to enable it to fund any claim 
payments or payments made in settlement or mitigation of claims 
payments under its surety bonds, including the Surety Bond(s).

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

Security received its New York State insurance license on September 
23, 1985. Financial Security and its two wholly owned subsidiaries 
are licensed to engage in the financial guaranty insurance business 
in 49 states, the District of Columbia and Puerto Rico.

Financial Security and its subsidiaries are engaged exclusively 
in the business of writing financial guaranty insurance, principally 
in respect of asset-backed and other collateralized securities 
offered in domestic and foreign markets. Financial Security and 
its subsidiaries also write financial guaranty insurance in respect 
of municipal and other obligations and reinsure financial guaranty 
insurance policies written by other leading insurance companies. 
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 is approximately 91.6% owned by US West, Inc. 
and 8.4% owned by The Tokio Marine and Fire Insurance Co., Ltd. 
("Tokio Marine"). US West, Inc. operates businesses involved in 
communications, data solutions, marketing services and capital 
assets, including the provision of telephone services in 14 states 
in the western and mid-western United States. Tokio Marine is 
the largest property and casualty insurance company in Japan. 
No shareholder of Financial Security is obligated to pay any debt 
of Financial Security or any claim under any insurance policy 
issued by Financial Security or to make any additional contribution 
to the capital of Financial Security.

As of March 31, 1993, 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 
$479,110,000 (unaudited) and $220,078,000 (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,


Page 13

approximately $628,119,000 (unaudited), and $202,493,000 (unaudited). 
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 by Financial Security or either of 
its subsidiaries 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 reinsures a portion of its liabilities 
under certain of its financial guaranty insurance policies with 
unaffiliated reinsurers under various quota share treaties and 
on a transaction-by-transaction basis. Such reinsurance is utilized 
by Financial Security as a risk management device and to comply 
with certain statutory and rating agency requirements; it does 
not alter or limit Financial Security's obligations under any 
financial guaranty insurance policy.

Financial Security's claims-paying ability is rated "Aaa" by Moody's 
Investors Service, Inc, and "AAA" by Standard & Poor's, Nippon 
Investors Service Inc., Duff & Phelps Inc. and Australian Ratings 
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") is a stock insurance company incorporated in the State of 
Wisconsin and a wholly-owned subsidiary of College Construction

holding company. As of December 31, 1994, the total policyholders' 
surplus of Connie Lee was approximately $106,000,000 (audited) 
and total admitted assets was approximately $194,000,000 (audited), 
as reported to the Commissioner of Insurance of the State of Wisconsin. 
Connie Lee's address is 2445 M Street, N.W., Washington D.C. 20037.

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 purchase price paid by such Trust will reduce 
payment to Unit holders of the interest and principal required 
to be paid on such Bonds. 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.

How is the Public Offering Price Determined?

Secondary Market Sales Charge. The sales charge assessed on Units 
sold in secondary market transactions is determined in accordance 
with the table set forth below based upon the number of years 
remaining to the maturity of each such Bond. The effect of this 
method of sales charge calculation will be that different sales 
charge rates will be applied to the various Bonds in a Trust portfolio 
based upon the maturities of such Bonds, in accordance with the 
following schedule.

Description Of Bond Ratings*
______________
*       As published by the rating companies.


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:

I.      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; 

II.     Nature of and provisions of the obligation;

III.    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.**
______________
**      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.


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.

Page 15


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.

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 larger 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

Page 16


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 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.

                           APPENDIX A
                       ALABAMA DISCLOSURE

Alabama Economy. Alabama's economy has experienced a major trend 
toward industrialization over the past two decades. By 1990, manufacturing 
accounted for 26.7% of Alabama's Real Gross State Product (the 
total value of goods and services produced in Alabama). During 
the 1960s and 1970s the State's industrial base became more diversified 
and balanced, moving away from primary textiles (including apparel), 
chemicals, rubber and plastics. Since the early 1980's, modernization 
of existing facilities and an increase in direct foreign investments 
in the State has made the manufacturing sector more competitive 
in domestic and international markets.

Among several leading manufacturing industries have been pulp 
and papers and chemicals, the development and growth of which 
have been made possible by abundant rainfall (the mean annual 
average of which varies between 52 and 68 inches) and a high pulpwood 
growth rate (averaging approximately one-half cord per acre per 
year). In recent years Alabama has ranked as the fifth largest 
producer of timber in the nation. Alabama has fresh water availability 
of twenty times present usage. The State's growing chemical industry 
has been the natural complement of production of wood pulp and 
paper. Mining, oil and gas production and service industries are 
also important to Alabama's economy. Coal mining is by far the 
most important mining activity. 

In recent years, the importance of service industries to the State's 
economy has increased significantly. The major service industries 
in the State are the general healthcare industries, most notably 
represented by the University of Alabama medical complex in Birmingham 
and the high technology research and development industries concentrated 
in the Huntsville area. The financial, insurance and real estates 
sectors have also shown strong growth over the last several years.

The economy in the State of Alabama recovered quickly from the 
recession of the early 1980s. Since 1983, the State has recovered 
and moved forward faster than the national average. The Alabama 
Development Office reported as of December 31, 1992, that for 
the sixth consecutive year more than two billion dollars were 
expended in Alabama for new and expanded industries. The State 
had new and expanding capital investment of $2.2 billion in 1991 
and $2.0 billion in 1992. These expenditures included 17,893 announced 
jobs created by 845 separate companies for 1991 and 19,582 announced 
jobs by 979 companies in 1992. From 1987-1991, $13.2 billion was 
invested in new or expanding industry in the State. Some of the 
largest investments during this period include Alabama Pine Pulp 
Company ($700 million); Mead Corporation ($300 million); EXXON 
Company, USA ($900 million); Gulf States Paper ($225 million) 
and United States Steel Corp. ($200 million). During 1992, three 
significant projects were announced by companies within the State. 
These projects are by Scott Paper Company ($344 million); Russell 
Corporation ($147 million) and Courtfaulds Fibers, Inc. ($125 million).

During the recent recession, State revenues suffered along with 
the rest of the nation. Growth in overall tax revenues was only 
about 3.4% from fiscal 1991 to 1992. Corporate income tax receipts 
declined slightly from 1991 to 1992. However, State tax collections 
were up by about 8.9% for the nine month period ending June 30, 
1993, as compared to the same period for fiscal 1992, indicating 
an economic recovery is in progress. Individual income tax receipts 
and sales tax receipts for the same nine month period increased 
8.0% and 7.8%, respectively.

Real Gross State Product. Real Gross State Product (RGSP) is a 
comprehensive measure of economic performance for the State of 
Alabama. Alabama's RGSP is defined as the total value of all final 
goods and services produced in the State in constant dollar terms. 
Hence, changes in RGSP reflect changes in final output. From 1986 
to 1992 RGSP originating in manufacturing increased by 2.5% per 
year while RGSP originating in all the non-manufacturing sectors 
grew by 2.1% per year. 

Those non-manufacturing sectors exhibiting large percentage increases 
in RGSP originating between 1986 and 1992 were Mining; Transportation, 
Communication and Public Utilities; and Services. From 1986 to 
1992 RGSP originating in Mining increased by 5.7% per year, Transportation, 
Communication and Public Utilities grew by 6.2% per year, and 
Services grew by 3.8% per year. The present movement toward diversification


Page A-1

of the State's manufacturing base and a similar present trend 
toward enlargement and diversification of the transportation, 
communication, and public utilities and service industries in 
the State are expected to lead to increased economic stability. 

Employment. There was a significant decrease in unemployment in 
the period 1985-1989 due to the economic recovery from the recession 
of the early 1980s. Since 1989, unemployment rates have come down 
more gradually due to the general nationwide reduction in activity 
and employment in the industrial sector.

Transportation. Alabama contains one of the largest networks of 
inland river systems in the nation. Across the northern section 
of the State, through the heartland and down to the Gulf of Mexico 
flow the waters of four major rivers offering barge transportation 
to industries and businesses that depend on the movement of large, 
heavy or bulky cargoes.

The Port of Mobile is one of the nation's busiest ports in tons 
of cargo handled. During the fiscal year ending September 30, 
1991, the Port of Mobile handled approximately 35,031,521 tons 
of cargo. It has been the largest port of entry in the United 
States for bauxite, a basic ingredient in aluminum. Other important 
imports handled at the Port of Mobile are manganese, iron ore, 
chrome ore, newsprint, wire and nails. In addition to coal, the 
State's most important export, the other significant exports passing 
through the Port of Mobile are soybeans, corn, flour, wheat, rice, 
lumber, scrap iron, paper and paper products, creosoted timbers, 
dry milk, iron, steel and iron and steel products.

Political subdivisions of the State of Alabama have limited taxing 
authority. In addition, the Alabama Supreme Court has held that 
a governmental unit may first use its taxes and other revenues 
to pay the expenses of providing necessary governmental services 
before paying debt service on its bonds, warrants or other indebtedness. 
The State has statutory budget provisions which result in a proration 
procedure in the event estimated budget resources in a fiscal 
year are insufficient to pay in full all appropriations for that 
year. Proration has a materially adverse effect on public entities 
that are dependent upon State funds subject to proration. 

Deterioration of economic conditions could adversely affect both 
tax and other governmental revenues, as well as revenues to be 
used to service various revenue obligations, such as industrial 
development obligations. Such difficulties could adversely affect 
the market value of the bonds held by the Alabama Trust and thereby 
adversely affect Unit holders. 

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 in the Alabama 
Trust 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 
the State and various agencies and political subdivisions located 
in the State. 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 Alabama 
Trust to pay interest on or principal of the Bonds.

                           APPENDIX B
                     CONNECTICUT DISCLOSURE

   
Investors should be aware that manufacturing was historically 
the most important economic activity within the State of Connecticut 
but, in terms of number of persons employed, manufacturing has 
declined in the last ten years while both trade and service-related 
industries have become more important, and in 1993 manufacturing 
accounted for only 19.2% of total non-agricultural employment 
in Connecticut. Defense-related business represents a relatively 
high proportion of the manufacturing sector; reductions in defense 
spending have already had a substantial adverse effect on Connecticut's 
economy, and the State's largest defense contractors have announced 
substantial planned labor force reductions scheduled to occur 
over the next four years. Connecticut is now in a recession, the 
depth and duration of which are uncertain. Moreover, while unemployment 
in the State as a whole has generally remained below the national 
level, as of May, 1993, the estimated rate of unemployment in 
Connecticut on a seasonally adjusted basis reached 7.4%, compared 
to 6.9% for the United States as a whole, and certain geographic 
areas in the State have been affected by high unemployment and 
poverty. The State derives over 70% of its revenues from taxes 
imposed by it, the most important of which had been the sales 
and use taxes and the corporation business tax, each of which 
is particularly sensitive to changes in the level of economic 
activity in the State, but the Connecticut income tax on individuals, 
trusts, and estates enacted in 1991 has superseded each of them 
in importance. There can be no assurance that general economic 
difficulties or the financial circumstances of the State or its 
towns and cities will not adversely affect the market value of 
the Bonds in the Connecticut Trust or the ability of the obligors 
to pay debt service on such Bonds.
    

The General Fund budget adopted by Connecticut for the 1986-87 
fiscal year contemplated both revenues and expenditures of $4,300,000,000. 
The General Fund ended the 1986-87 fiscal year with a surplus 
of $365,200,000. The General Fund budget for the 1987-88 fiscal 
year contemplated General Fund revenues and expenditures of $4,915,800,000. 
However, the General Fund ended the 1987-88 fiscal year with a 
deficit of $115,600,000. The General Fund budget adopted for the 
1988-89 fiscal year anticipated that General Fund expenditures 
of $5,551,000,000 and certain educational expenses of $206,700,000 
not previously paid through the General Fund would be funded in 
part from surpluses of prior years and in part from higher tax 
revenues projected to result from tax laws in effect for the 1987-88 
fiscal year and stricter enforcement thereof; a substantial deficit 
was projected during the third quarter of the 1988-89 fiscal year, 
but largely because of tax law changes that took effect before 
the end of the fiscal year, the deficit was kept to $28,000,000. 
The General Fund budget adopted for the 1989-90 fiscal year anticipated 
expenditures of approximately $6,224,500,000 and, by virtue of 
tax increase legislation enacted to take effect generally at the 
beginning of the fiscal year, revenues slightly exceeding such 
amount. However, largely because of tax revenue shortfalls, the 
General Fund ended the 1989-90 fiscal year with a deficit for 
the year of $259,500,000, wiping out reserves for such events 
built up in prior years. The General Fund budget adopted for the 
1990-91 fiscal year anticipated expenditures of $6,433,000,000, 
but no significant new or increased taxes were enacted. Primarily 
because of significant declines in tax revenues and unanticipated 
expenditures reflective of economic adversity, the General Fund 
ended the 1990-91 fiscal year alone with a further deficit of 
$809,000,000.

   
A General Fund budget for the 1991-92 fiscal year was not enacted 
until August 22, 1991. This budget anticipated General Fund expenditures 
of $7,007,861,328 and revenues of $7,426,390,000. Projected decreases 
in revenues resulting from a 25% reduction in the sales tax rate 
effective October 1, 1991, the repeal of the taxes on the capital 
gains and interest and dividend income of resident individuals 
for years starting after 1991, and the phase-out of the corporation 
business tax surcharge over two years commencing with taxable 
years starting after 1991 are expected to be more than offset 
by a new general income tax imposed at effective rates not to 
exceed 4.5% on the Connecticut taxable income of resident and 
non-resident individuals, trusts, and estates. The General Fund 
ended the 1991-92 fiscal year with an operating surplus of $110,000,000. 
The General Fund budget for the 1992-93 fiscal year anticipated 
General Fund expenditures of $7,372,062,859 and revenues of $7,372,210,000. 
The General Fund ended the 1992-93 fiscal year with


Page B-1

an operating surplus of $113,500,000. Balanced General Fund budgets 
for the biennium ending June 30, 1995, were adopted in 1993 appropriating 
expenditures of $7,828,900,000 for the 1993-94 fiscal year and 
$8,266,000,000 for the 1994-95 fiscal year. The General Fund ended 
the 1993-94 fiscal year with a surplus of $19,700,000. In 1994 
the budgeted General Fund appropriations for the 1994-95 fiscal 
year were increased to $8,567,200,000. General Fund budgets for 
the biennium ending June 30, 1997, were adopted in 1995 anticipating 
expenditures of $8,987,907,123 and revenues of $8,988,180,000 
for the 1995-96 fiscal year and anticipating expenditures of $9,311,125,170 
and revenues of $9,311,700,000 for the 1996-97 fiscal year. In 
addition, expenditures of Federal, State, and local funds in the 
twelve years started July 1, 1984, for repair of the State's roads 
and bridges now projected at $9,400,000,000 are anticipated, a 
portion of the State's $4,100,000,000 share of which would be 
financed by bonds expected to total $3,700,000,000 and by direct 
payments both of which would be supported by a Special Transportation 
Fund first created by the General Assembly for the 1984-85 fiscal year.
    

   
To fund operating cash requirements, prior to the 1991-92 fiscal 
year the State borrowed up to $750,000,000 pursuant to authorization 
to issue commercial paper and on July 29, 1991, it issued $200,000,000 
of General Obligation Temporary Notes, none of which temporary 
borrowings are currently outstanding. To fund the cumulative General 
Fund deficit for the 1989-90 and 1990-91 fiscal years, the legislation 
enacted August 22, 1991, authorized the State Treasurer to issue 
Economic Recovery Notes up to the aggregate amount of such deficit, 
which must be payable no later than June 30, 1996; at least $50,000,000 
of such Economic Recovery Notes, but not more than a cap amount, 
is to be retired each fiscal year commencing with the 1991-92 
fiscal year, and any unappropriated surplus up to $205,000,000 
in the General Fund at the end of each of the three fiscal years 
commencing with the 1991-92 fiscal year must be applied to retire 
such Economic Recovery Notes as may remain outstanding at those 
times. On September 25, 1991, and October 24, 1991, the State 
issued $556,610,000 and $325,002,000, respectively, of such Economic 
Recovery Notes, of which $455,610,000 was outstanding as of March 1, 1995.
    

   
As a result of the State's budget problems, the ratings of its 
general obligation bonds were reduced by Standard & Poor's from 
AA+ to AA on March 29, 1990, and by Moody's from Aa1 to Aa on 
April 9, 1990. Moreover, because of these problems, on September 
13, 1991, Standard & Poor's reduced its ratings of the State's 
general obligation bonds and certain other obligations that depend 
in part on the creditworthiness of the State to AA-. On March 
7, 1991, Moody's downgraded its ratings of the revenue bonds of 
four Connecticut hospitals because of the effects of the State's 
restrictive controlled reimbursement environment under which they 
have been operating. On March 17, 1995, Fitch reduced its rating 
of the State's general obligation bonds from AA+ to AA.
    

General obligation bonds issued by Connecticut municipalities 
are payable primarily only from ad valorem taxes on property subject 
to taxation by the municipality. Certain Connecticut municipalities 
have experienced severe fiscal difficulties and have reported 
operating and accumulated deficits in recent years. The most notable 
of these is the City of Bridgeport, which filed a bankruptcy petition 
on June 7, 1991. The State opposed the petition. The United States 
Bankruptcy Court for the District of Connecticut has held that 
Bridgeport has authority to file such a petition but that its 
petition should be dismissed on the grounds that Bridgeport was 
not insolvent when the petition was filed. Regional economic difficulties, 
reductions in revenues, and increased expenses could lead to further 
fiscal problems for the State and its political subdivisions, 
authorities and agencies. Difficulty in payment of debt service 
on borrowings could result in declines, possibly severe, in the 
value of their outstanding obligations and increases in their 
future borrowing costs.

                        IDAHO DISCLOSURE

   
Idaho's economic performance over the last several years has been 
significantly better than the national average. The State's 4% 
annual growth rate in 1992 and 1993 ranked second in the nation. 
The State's overall employment picture, which previously had been 
more dependent on natural resource-related industries, has diversified, 
with steady growth in the service and manufacturing sectors. Population 
has increased 13.1% since 1988, to 1.1 million in 1994, with a 
steady shift from rural to urban areas.
    

   
Personal income in Idaho (in millions) was $18,783 in 1993, a 
6.5% increase over 1992. For 1994 and 1995, personal income is 
expected to increase 8.1% and 7.3%, respectively, to $20,297 in 
1994 and $21,771 in 1995.
    

   
In 1993, the average unemployment rate of 6.1% for Idaho was lower 
than the national average of 6.8%. In December of 1994 Idaho's 
rate was higher than the national rate. Although not strictly 
comparable to the 1993 rates, the preliminary seasonally adjusted 
unemployment rates for December of 1994 were 6.4% for Idaho and 
5.4% for the U.S.
    

   
Housing starts in Idaho had increased steadily from 1991 to 1993, 
from 6,580 in 1991, to 9,595 in 1992 and 11,451 in 1993. Housing 
starts are expected to remain stable in 1994 and 1995, with a 
forecast of 11,868 for 1994 and 11,705 for 1995.
    

   
The amount of total funds available to the General Fund in fiscal 
year 1995 is estimated to be $1,273,490,300. This consists of 
an estimated $18,230,700 beginning balance plus $1,255,259,600 
in revenue in fiscal year 1995. General Fund expenditures authorized 
for fiscal year 1995 are $1,264,200,400. This leaves an estimated 
free-fund balance of $9,289,900 in the General Fund at the end 
of fiscal year 1995.
    

   
The original Executive revenue forecast of $1,255,665,000 for 
fiscal year 1995 reflected 8.5% growth over fiscal year 1994. 
This revenue forecast was reviewed by the legislature's Joint 
Economic Outlook Committee and found to be reasonable. It has 
been adjusted to reflect a net reduction of $405,400 as a result 
of the enactment of 21 bills that either increased or decreased 
revenue to the General Fund.
    

   
General Fund revenues consist primarily of the sales tax and the 
individual and corporate income tax. Base revenue growth in the 
individual income tax is forecast at 10.1% in fiscal year 1995. 
Sales tax revenues are forecast to grow by 8.7% in fiscal year 
1995, and corporate income tax revenues are forecast to grow by 
6.2%. Product taxes, at slightly over 1% of total General Fund 
revenues, are forecast to fall by 1/2% in fiscal year 1995 due 
to changes in legislation. Miscellaneous revenues, dominated by 
the insurance premium tax and interest earnings, are a little 
over 4% of total General Fund Revenues. They are forecast to decline 
by 4.4% as a result of legislative changes in fiscal year 1995. 
The net growth rate for total General Fund revenue in fiscal year 
1995 after revenue adjustment is 8.6%. Expenditures in fiscal 
year 1995 consist of $1,086,244,000 in base spending plus $177,956,400 
in enhancements, inflation adjustments, salary increases and various 
one-time outlays.
    

   
State employee salary increases of 5.4% cost $20,880,200, while 
a similar increase for public school teachers cost $34,359,500. 
The state has a 27th payroll period in fiscal year 1995, at a 
one-time cost of $12,532,200. Personnel benefits cost an additional 
$15,722,400 and phase three of the retirement enhancement costs 
$6,581,600. Total employee compensation related increases in fiscal 
year 1995 are $90,075,900.
    

   
Annualizations cost $3,669,200, fund shifts are $2,759,100, inflation 
adjustments are $12,855,300 and replacement capital outlays are 
$5,631,200. Program enhancements cost $61,317,100.
    

   
The single largest enhancement is for public schools, at $34,168,500. 
Health and Welfare received $10,248,300 in enhancements; Colleges 
and Universities received $4,665,500; Vocational Education received 
$1,924,200; Public Television received $1,207,300 and the Judicial 
Branch received $1,187,000. The remaining $7,916,300 in enhancements 
goes to 33 other programs. No other entity will receive more than 
one million dollars in enhancements in fiscal year 1995.

some of the financial difficulties which may impact certain issuers

conditions to which the issuers in the Idaho Advantage Trust 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 the State 
and various agencies and political subdivisions located in the 
State. 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 Idaho Advantage 
Trust to pay interest on or principal of the Bonds.

                        WITNESSETH THAT:

                             PART I

                             PART II
                                
              SPECIAL TERMS AND CONDITIONS OF TRUST
     
     The following special terms and conditions are hereby agreed
to:
     
     (a)  The Bonds defined in Section 1.01(5) listed in Schedule
A hereto have been deposited in trust under this Trust Agreement.
     
     (b)   The fractional undivided interest in and ownership  of
the  Trust  Fund  represented by each Unit for  a  Trust  on  the

Interest in the Trust per Unit" in the Prospectus.
     
     (c)   The number of units in a Trust on the Initial Date  of
Deposit  referred  to  in Section 2.03 is  set  forth  under  the
caption  "Summary of Essential Information - Number of Units"  in
the Prospectus.
     
     (d)  The approximate amount, if any, which the Trustee shall
be  required to advance out of its own funds and cause to be paid
to  the Depositor pursuant to the second sentence of Section 3.05
shall  be  the  amount per Unit for each Trust that  the  Trustee
agreed to reduce its fee or pay Trust Fund expenses set forth  in
the  footnotes to the "Special Trust Information" for each  Trust
in  the  Prospectus  times the number of  units  for  such  Trust
referred to in Part II (c) of this Trust Agreement.
     
     (e)   For  each Trust the First General Record Date and  the
amount  of  the  second distribution of funds from  the  Interest
Account shall be the record date for the Interest Account and the
amount  set forth under "Special Trust Information-Distributions"
for such Trust in the Prospectus.
     
     (f)   For each Trust the "First Settlement Date" is the date
set   forth   under   "Summary  of  Essential   Information-First
Settlement Date" for such Trust in the Prospectus.
     
     (g)  The first sentence of Section 3.15. shall be amended to
read as follows:
     
     "As   compensation   for  providing  supervisory   portfolio
services  under  this Indenture, the Portfolio  Supervisor  shall
receive  against a statement or statements therefor submitted  to
the  Trustee monthly or annually an aggregate annual  fee  in  an
amount which shall not exceed the amount set forth under "Summary
of Essential Information-Supervisory Fee" in the Prospectus times
the number of Units outstanding as of January 1 of such year (or,
with  respect to the first calendar year of a Trust, the date  of
deposit),  but in no event shall such compensation when  combined
with all compensation received from other series of the Fund  for
providing  such supervisory services in any calendar year  exceed
the aggregate cost to the Portfolio Supervisor for providing such
services  (such annual fee to be pro rated for any calendar  year
in  which the Portfolio Supervisor provides services during  less
than the whole of such year)."
     
     (h)  Section 1.01(4) shall be amended to read as follows:
     
     "(4)  "Portfolio Supervisor" shall mean First Trust Advisors
L.P.  and  its successors in interest, or any successor portfolio
supervisor appointed as hereinafter provided."
     
     (i)   The  first  four sentences of Section  6.04  shall  be
amended in their entirety to read as follows:
     
     "For services performed under this Indenture the Trustee
shall be paid an amount per annum specified in Part II of the
Trust  Agreement in respect of which payment is made pursuant
to  Section  3.05.  The Trustee's compensation  shall  accrue
daily and be computed on the basis of the greatest number  of
Units  in  each  Trust  at any time during  the  period  with
respect  to  which such compensation is being computed  (such
period  being  the period commencing with the next  preceding
Distribution  Date,  or  the  initial  date  of  deposit,  as
appropriate,   and  running  to,  but  not   including,   the
Distribution  Date  on which such computation  is  made)  and
shall   be   apportioned  among  the  respective   plans   of
distribution  in effect as of January 1 next  preceding  such
computation.   During  the  first  year  of  a  Trust,   such
compensation shall be reduced by the amount of interest which
accrues  on "when-issued" Bonds and Contract Bonds  from  the
First  Settlement Date, as defined in Part II  of  the  Trust
Agreement, to the respective delivery dates of such Bonds and
Contract Bonds."
     
     (j)  The Trustee's annual fee referred to in Section 6.04 is
set  forth  for each Trust under "Special Trust Information"  for
such Trust in the Prospectus.
     
     (k)  The first paragraph of Section 3.05 shall be amended to
read as follows:
     
     "The  Trustee,  as  of the "First Settlement  Date",  as
defined in Part II of the Trust Agreement, shall advance from
its  own  funds and shall pay to the Depositor the amount  of
interest accrued to such date on the Bonds deposited  in  the
respective  Trusts.  The Trustee, as of the "First Settlement
Date,"  as  defined in Part II of the Trust Agreement,  shall
also  advance to the Trust from its own funds and  distribute
to the Depositor the amount specified in Part II of the Trust
Agreement, which is the amount by which the Trustee's fee  is
reduced  and Trust expenses assumed by the Trustee in respect
of  interest  accrued on "when-issued" Bonds and on  Contract
Bonds  delivered  to  the  Trustee subsequent  to  the  First
Settlement Date pursuant to Section 6.04.  The Trustee  shall
be  entitled  to  reimbursement, without interest,  for  such
advancements from interest received by the Trust.  Subsequent
distributions shall be made as hereinafter provided."
     
     (l)   Section 2.01 of Article II of the Standard  Terms  and
Conditions of Trust is hereby amended by inserting "(a)" prior to
the  beginning  of  the  text of the  paragraph  and  adding  the
following additional paragraphs:
     
     "(b)  From time to time following the Initial  Date  of
Deposit,  the  Depositor  is  hereby  authorized,   in   its
discretion,  to  assign,  convey to  and  deposit  with  the
Trustee additional Bonds, in bearer form or duly endorsed in
blank  or  accompanied  by  all  necessary  instruments   of
assignment   and  transfer  in  proper  form  (or   Contract
Obligations relating to such Bonds), to be held, managed and
applied by the Trustee as herein provided.  Such deposit  of
additional Bonds shall be made, in each case, pursuant to  a
Notice of Deposit of Additional Bonds from the Depositor  to
the Trustee.  The Depositor, in each case, shall ensure that
each  deposit  of additional Bonds pursuant to this  Section
shall  be,  as  nearly as is practicable, in  the  identical
ratio as the Percentage Ratio for such Bonds as is specified
in  the  Prospectus for each Trust and the  Depositor  shall
ensure  that such Bonds are identical to those deposited  on
the  Initial  Date of Deposit.  The Depositor shall  deliver
the  additional Bonds which were not delivered  concurrently
with   the  deposit  of  additional  Bonds  and  which  were
represented by Contract Obligations within 10 calendar  days
after  such  deposit  of additional Bonds  (the  "Additional
Bonds  Delivery Period").  If a contract to buy  such  Bonds
between the Depositor and seller is terminated by the seller
thereof  for any reason beyond the control of the  Depositor
or  if  for any other reason the Bonds are not delivered  to
the Trust by the end of the Additional Bonds Delivery Period
for  such deposit, the Trustee shall immediately draw on the
Letter  of Credit, if any, in its entirety, apply the monies
in  accordance with Section 2.01(d), and the Depositor shall
forthwith   take   the   remedial   action   specified    in
Section 3.14.
     
     (c)   In  connection  with the  deposits  described  in
Section 2.01 (a) and (b), the Depositor has, in the case  of
Section   2.01(a)  deposits,  and,  prior  to  the   Trustee
accepting  a  Section 2.01(b) deposit,  will,  deposit  cash
and/or Letter(s) of Credit (meeting the conditions set forth
in  Section  2.07) in an amount sufficient to  purchase  the
Contract  Obligations  (the "Purchase Amount")  relating  to
Bonds which are not actually delivered to the Trustee at the
time  of  such  deposit, the terms of which  unconditionally
allow  the  Trustee  to  draw on  the  full  amount  of  the
available  Letter of Credit.  The Trustee may  deposit  such
cash or cash drawn on the Letter of Credit in a non-interest
bearing account for the Trust.
     
     (d)   In  the  event  that  the  purchase  of  Contract
Obligations   pursuant  to  any  contract   shall   not   be
consummated in accordance with said contract or if the Bonds
represented by Contract Obligations are not delivered to the
Trust in accordance with Section 2.01(a) or 2.01(b) and  the
monies, or, if applicable, the monies drawn on the Letter of
Credit,  deposited  by the Depositor are  not  utilized  for
Section  3.14  purchases of New Bonds, such  funds,  to  the
extent  of the purchase price of Special Bonds for which  no
New  Bond  was acquired pursuant to Section 3.14,  plus  all
amounts  described  in  the next succeeding  two  sentences,
shall  be  credited to the Principal Account and distributed
pursuant to Section 3.05 to Unit holders of record as of the
Record  Date  next following the failure of consummation  of
such purchase.  The Depositor shall cause to be refunded  to
each  Unit  holder his pro rata portion of the sales  charge
levied on the sale of Units to such Unit holder attributable
to  such  Failed  Contract Obligation.  The Depositor  shall
also  pay  to  the  Trustee, for distribution  to  the  Unit
holders, interest on the amount of the purchase price to the
Trust  of the Special Bonds, at the rate of 5% per annum  to
the date the Depositor notifies the Trustee that no New Bond
will  be  purchased or, in the absence of such notification,
to  the expiration date for purchase of a New Bond specified
in Section 3.14.  Any amounts remaining from monies drawn on
the  Letter  of  Credit which are not used to  purchase  New
Bonds  or  are  not used to provide refunds to Unit  holders
shall be paid to the Depositor.
     
     (e)   The  Trustee is hereby irrevocably authorized  to
effect  registration  or transfer  of  the  Bonds  in  fully
registered form to the name of the Trustee or to the name of
its nominee.
     
     (f)   In connection with and at the time of any deposit
of   additional  Bonds  pursuant  to  Section  2.01(b),  the
Depositor  shall exactly replicate Cash (as  defined  below)
received or receivable by the Trust as of the date  of  such
deposit.   For purposes of this paragraph, "Cash" means,  as
to the Principal Account, cash or other property (other than
Bonds) on hand in the Principal Account or receivable and to
be  credited to the Principal Account as of the date of  the
deposit  (other  than  amounts to be distributed  solely  to
persons  other than holders of Units created by the deposit)
and, as to the Income Account, cash or other property (other
than  Bonds)  received by the Trust as of the  date  of  the
deposit  or receivable by the Trust in respect of  a  coupon
date  which has occurred or will occur before the Trust will
be  the holder of record of a Bond, reduced by the amount of
any  cash  or other property received or receivable  on  any
Bonds   allocable   (in  accordance   with   the   Trustee's
calculation  of  the monthly distribution  from  the  Income
Account pursuant to Section 3.05) to a distribution made  or
to  be  made in respect of a Record Date occurring prior  to
the deposit.  Such replication will be made on the basis  of
a  fraction, the numerator of which is the number  of  Units
created by the deposit and the denominator of which  is  the
number  of Units which are outstanding immediately prior  to
the deposit."
     
     (m)   Article  II  of the Standard Terms and  Conditions  of
Trust  is  hereby  amended by inserting the  following  paragraph
which shall be entitled Section 2.07.:
     
     "Section 2.07. Letter of Credit.  The Trustee shall not
accept any Letter of Credit under this Indenture unless  the
stated  expiration date of the Letter of Credit is at  least
thirty  days from the respective date of deposit of Contract
Obligations  pursuant to Section 2.01(a)  or  2.01(b).   The
Trustee is authorized to downpost the amount available under
the Letter of Credit, if any, deposited by the Depositor  by
an   amount   equal  to  the  purchase  price  of   Contract
Obligations representing Bonds delivered to the Trust on the
date of delivery of such Bonds."
     
     (n)   Section 3.05 of Article III of the Standard Terms  and
Conditions  of  Trust is hereby amended to include the  following
subsection:
     
     "Section  3.05(e)     deduct from the Interest  Account
or,  to  the extent funds are not available in such Account,
from  the  Principal Account and pay to  the  Depositor  the
amount  that it is entitled to receive pursuant  to  Section
3.16.
     
     (o)   Article  III of the Standard Terms and  Conditions  of
Trust  is  hereby  amended by inserting the following  paragraphs
which shall be entitled Section 3.16.:
     
     "Section 3.16. Bookkeeping and Administrative Expenses.
As   compensation   for  providing  bookkeeping   or   other
administrative services of a character described in  Section
26(a)(2)(C)  of the Investment Company Act of  1940  to  the
extent  such  services  are  in  addition  to,  and  do  not
duplicate,  the  services to be provided  hereunder  by  the
Trustee  or  the  Portfolio Supervisor, the Depositor  shall
receive against a statement or statements therefor submitted
to  the Trustee monthly or annually an aggregate annual  fee
in  an  amount which shall not exceed $0.10 times the number
of Units outstanding as of January 1 of such year except for
a  year  or  years  in which an initial offering  period  as
determined  by  Section 4.01 of this  Indenture  occurs,  in
which  case  the fee for a month is based on the  number  of
Units outstanding at the end of such month (such annual  fee
to be pro rated for any calendar year in which the Depositor
provides  service during less than the whole of such  year),
but  in no event shall such compensation when combined  with
all  compensation received from other unit investment trusts
for which the Depositor hereunder is acting as Depositor for
providing  such bookkeeping and administrative  services  in
any calendar year exceed the aggregate cost to the Depositor
of  providing such services to such unit investment  trusts.
Such  compensation  may,  from time  to  time,  be  adjusted
provided that the total adjustment upward does not,  at  the
time  of such adjustment, exceed the percentage of the total
increase,  after  the  date hereof, in consumer  prices  for
services  as  measured  by the United States  Department  of
Labor Consumer Price Index entitled "All Services Less  Rent
of Shelter" or similar index, if such index should no longer
be published.  The consent or concurrence of any Unit holder
hereunder  shall not be required for any such adjustment  or
increase.   Such compensation shall be paid by the  Trustee,
upon  receipt  of invoice therefor from the Depositor,  upon
which, as to the cost incurred by the Depositor of providing
services  hereunder  the  Trustee may  rely,  and  shall  be
charged  against the Interest and Principal Accounts  on  or
before  the  Distribution Date following the Monthly  Record
Date  on  which  such period terminates.  The Trustee  shall
have  no liability to any Certificateholder or other  person
for any payment made in good faith pursuant to this Section.
     
     If  the  cash  balance  in the Interest  and  Principal
Accounts  shall  be  insufficient  to  provide  for  amounts
payable  pursuant  to this Section 3.16, the  Trustee  shall
have  the power to sell (i) Bonds from the current  list  of
Bonds designated to be sold pursuant to Section 5.02 hereof,
or (ii) if no such Bonds have been so designated, such Bonds
as  the  Trustee may see fit to sell in its own  discretion,
and to apply the proceeds of any such sale in payment of the
amounts payable pursuant to this Section 3.16.
     
     Any  moneys payable to the Depositor pursuant  to  this
Section  3.16 shall be secured by a prior lien on the  Trust
Fund except that no such lien shall be prior to any lien  in
favor  of  the Trustee under the provisions of Section  6.04
herein.
     
     (p)  All provisions regarding the Distribution Date included
in  Section  3.05  of  Article III  of  the  Standard  Terms  and
Conditions of Trust are hereby amended to change the Distribution
Date from the first day of the month following the Record Date to
the last day of the month in which the Record Date occurs.
     
     (q)   Section  3.01 of the Standard Terms and Conditions  of
Trust shall be replaced in its entirety with the following:
     
     "Section  3.01.   Initial Cost.  The  expenses  incurred  in
establishing  a  Trust,  including  the  cost  of   the   initial
preparation  and  typesetting  of  the  registration   statement,
prospectuses (including preliminary prospectuses), the indenture,
and   other   documents  relating  to  a   Trust,   printing   of
Certificates, Securities and Exchange Commission and  state  blue
sky  registration fees, the costs of the initial valuation of the
portfolio and audit of a Trust, the initial fees and expenses  of
the  Trustee, and legal and other out-of-pocket expenses  related
thereto,  but not including the expenses incurred in the printing
of  preliminary prospectuses and prospectuses, expenses  incurred
in   the   preparation  and  printing  of  brochures  and   other
advertising  materials and any other selling  expenses  shall  be
borne  by the Trust, provided, however, the Trust shall not  bear
such  expenses in excess of the amount shown in the Statement  of
Condition  included in the Prospectus, and any such excess  shall
be  borne  by  the  Depositor.  To the extent the  funds  in  the
Interest   and   Principal  Accounts  of  the  Trust   shall   be
insufficient to pay the expenses borne by the Trust specified  in
this Section 3.01, the Trustee shall advance out of its own funds
and  cause  to be deposited and credited to the Interest  Account
such  amount  as  may  be  required to  permit  payment  of  such
expenses.   The Trustee shall be reimbursed for such  advance  in
the  manner  provided  in Section 3.05,  and  the  provisions  of
Section  6.04  with respect to the reimbursement of disbursements
for  Trust expenses, including, without limitation, the  lien  in
favor  of  the  Trustee therefor, shall apply to the  payment  of
expenses  made  pursuant  to  this  Section.   For  purposes   of
calculation of distributions under Section 3.05 and the  addition
provided in clause (d) of Section 5.01, the expenses borne by the
Trust  pursuant to this Section shall be deemed to  accrue  at  a
daily  rate over the time period specified for their amortization
provided  in  the  Prospectus; provided,  however,  that  nothing
herein  shall  be  deemed to prevent, and the  Trustee  shall  be
entitled to full reimbursement for any advances made pursuant  to
this Section no later than the termination of the Trust.
     
     (r)  Section 6.01(i) of the Standard Terms and Conditions of
Trust shall be amended by deleting the first word of such Section
and replacing it with the following:
     
     "Except as provided in Section 3.01, no"
     
     (s)   Section  8.04  is  hereby  amended  by  inserting  the
following at the end of such section:
     
     ", except as provided in Section 3.01"
     
     (t)   The  second sentence of the first paragraph of Section
5.01  of  the  Standard Terms and Conditions of  Trust  shall  be
amended by deleting the word "and" appearing immediately prior to
subsection  (c) of such sentence and inserting the  following  at
the end of such sentence:
     
     ", and (d) amounts representing organizational expenses paid
less  amounts representing accrued organizational expenses  of  a
Trust."
     
     
                                
                            PART III
     
     Notwithstanding any provision to the contrary  contained  in
the  Standard Terms and Conditions of Trust and in  lieu  of  the
receipt  of  Certificates evidencing ownership of  Units  of  the
Fund, the Sponsor or any Underwriter of the Fund listed under the
caption  "Underwriting" in the Prospectus,  at  its  option,  may
elect  that  Units of the Fund owned by it be reflected  by  book
entry  on the books and records of the Trustee.  For all purposes
such  Sponsor  or Underwriter shall be deemed the owner  of  such
Units  as if a Certificate evidencing ownership of Units  of  the
Fund  had  actually  been  issued  by  the  Trustee.   The  Units
reflected  by book entry on the books and records of the  Trustee
may  be  transferable by the registered owner of  such  Units  by
written  instrument  in form satisfactory to  the  Trustee.   The
registered  owner of Units reflected by book entry on  the  books
and  records of the Trustee shall have the right at any  time  to
obtain Certificates evidencing ownership of such Units.
     
     IN  WITNESS  WHEREOF,  Nike Securities L.P.,  United  States
Trust  Company  of New York, Securities Evaluation Service,  Inc.
and  First  Trust  Advisors  L.P. have  each  caused  this  Trust
Agreement to be executed and the respective corporate seal to  be
hereto   affixed  and  attested  (if  applicable)  by  authorized
officers; all as of the day, month and year first above written.

     Re:          The First Trust Combined Series 251

Gentlemen:
     
     We  have  served  as  counsel for Nike Securities  L.P.,  as
Sponsor and Depositor of The First Trust Combined Series 251,  in
connection  with  the preparation, execution and  delivery  of  a
Trust  Agreement dated August 9, 1995 among Nike Securities L.P.,
as  Depositor,  United  States Trust  Company  of  New  York,  as
Trustee,  Securities Evaluation Service, Inc., as Evaluator,  and
First  Trust Advisors L.P., as Portfolio Supervisor, pursuant  to
which  the  Depositor  has delivered to and deposited  the  Bonds
listed in Schedule A to the Trust Agreement with the Trustee  and
pursuant  to which the Trustee has issued to or on the  order  of
the Depositor a certificate or certificates representing units of
fractional  undivided  interest in  and  ownership  of  the  Fund
created under said Trust Agreement.
     
     In  connection  therewith, we have examined  such  pertinent
records  and  documents  and matters of law  as  we  have  deemed
necessary  in  order  to  enable  us  to  express  the   opinions
hereinafter set forth.
     
     Based upon the foregoing, we are of the opinion that:

      1.   The execution and delivery of the Trust Agreement  and
the  execution and issuance of certificates evidencing the  Units
in the Fund have been duly authorized; and

      2.   the certificates evidencing the Units in the Fund when
duly  executed and delivered by the Depositor and the Trustee  in
accordance   with   the  aforementioned  Trust  Agreement,   will
constitute  valid  and binding obligations of the  Fund  and  the
Depositor in accordance with the terms thereof.

      We  hereby  consent  to the filing of this  opinion  as  an
exhibit   to  the  Registration  Statement  (File  No.  33-61553)
relating  to the Units referred to above, to the use of our  name
and  to  the reference to our firm in said Registration Statement
and in the related Prospectus.

                                                 Respectfully submitted,

            Re:  The First Trust Combined Series 251

Gentlemen:
     
     We   have  served  as  counsel  for  Nike  Securities  L.P.,
Depositor of The First Trust Combined Series 251 (the "Fund")  in
connection  with  the  issuance of Units of fractional  undivided
interest  in  said Fund under a Trust Agreement dated  August  9,
1995  (the "Indenture") among Nike Securities L.P., as Depositor,
United  States Trust Company of New York, as Trustee,  Securities
Evaluation Service, Inc., as Evaluator, and First Trust  Advisors
L.P., as Portfolio Supervisor.
     
     In  this  connection,  we  have  examined  the  Registration
Statement, the form of Prospectus proposed to be filed  with  the
Securities and Exchange Commission, the Indenture and such  other
instruments and documents as we have deemed pertinent.
     
     Based upon the foregoing, and upon an investigation of  such
matters  of  law as we consider to be applicable, we are  of  the
opinion that, under existing federal income tax law:

     (i)   Each  Trust is not taxable as an association  but
will be governed by the provisions of Subchapter J (relating
to  Trusts) of Chapter 1, Internal Revenue Code of 1986 (the
"Code").
     
     (ii)  Each  Certificateholder  will  be  considered  as
owning a share of each asset of the respective Trust in  the
proportion  that the number of Units of such Trust  held  by
him  bears to the total number of Units outstanding of  such
Trust.   Under Subpart E, Subchapter J of Chapter 1  of  the
Code, income of the Trust will be treated as income of  each
Certificateholder in the proportion described, and  an  item
of Trust income will have the same character in the hands of
a  Certificateholder as it would have in the  hands  of  the
Trustee.   Accordingly, to the extent that the income  of  a
Trust  consists  of  interest and  original  issue  discount
excludable from gross income under Section 103 of the  Code,
such income will be excludable from federal gross income  of
the   Certificateholder,   except   in   the   case   of   a
Certificateholder  who is a substantial user  (or  a  person
related  to  such  user)  of  a  facility  financed  through
issuance  of  any  industrial development bonds  or  certain
private  activity bonds held by the Trust.  In the  case  of
such  Certificateholder who is a substantial  user  (and  no
other)  interest received and original issue  discount  with
respect   to  his  Units  attributable  to  such  industrial
development  bonds  or  such  private  activity   bonds   is
includable in his gross income.  To the extent a Trust holds
Bonds that are "specified private activity Bonds" within the
meaning    of    Section   57(a)(5)   of   the    Code,    a
Certificateholder's pro rata portion of the income  on  such
Bonds  will be included as an item of tax preference in  the
computation  of  the alternative minimum tax  applicable  to
individuals,  trusts  and  corporations.   In  the  case  of
certain  corporations,  interest on  all  of  the  Bonds  is
included  in computing the alternative minimum tax  pursuant
to  Section  56(c) of the Code, the environmental  tax  (the
"Superfund Tax") imposed by Section 59A of the Code, and the
branch  profits tax imposed by Section 884 of the Code  with
respect to U.S. branches of foreign corporations.
     
     (iii)      Gain  or  loss  will  be  recognized  to   a
Certificateholder  upon redemption or  sale  of  his  Units.
Such  gain or loss is measured by comparing the proceeds  of
such redemption or sale with the adjusted basis of the Units
represented  by  his Certificate.  Before  adjustment,  such
basis  would  normally be cost if the Certificateholder  had
acquired  his Units by purchase, plus his aliquot  share  of
advances  by  the  Trustee to the respective  Trust  to  pay
interest  on  Bonds  delivered after the Certificateholder's
settlement date to the extent that such interest accrued  on
the  Bonds  during  the period from the  Certificateholder's
settlement date to the date such Bonds are delivered to  the
Trust, but only to the extent that such advances are  to  be
repaid to the Trustee out of interest received by such Trust
with respect to such Bonds. In addition, such basis will  be
increased  by the Certificateholder's aliquot share  of  the
accrued  original issue discount with respect to  each  Bond
held  by  the  Trust  with respect to  which  there  was  an
original issue discount at the time the Bond was issued  and
reduced by the annual amortization of bond premium, if  any,
on Bonds held by the Trust.
     
     (iv)  If  the Trustee disposes of an asset of  a  Trust
(whether  by  sale,  payment  on  maturity,  redemption   or
otherwise),   gain   or   loss   is   recognized   to    the
Certificateholder  and  the amount thereof  is  measured  by
comparing the Certificateholder's aliquot share of the total
proceeds  from  the  transaction  with  his  basis  for  his
fractional interest in the asset disposed of.  Such basis is
ascertained  by  apportioning the tax basis  for  his  Units
among  each of the assets of such Trust (as of the  date  on
which  his Units were acquired) ratably according  to  their
values as of the valuation date nearest the date on which he
purchased  such Units.  A Certificateholder's basis  in  his
Units  and of his fractional interest in each asset  of  the
Trust must be reduced by the amount of his aliquot share  of
interest  received by the Fund, if any, on  Bonds  delivered
after  the Certificateholder's settlement date to the extent
that  such  interest accrued on the Bonds during the  period
from  the  Certificateholder's settlement date to  the  date
such  Bonds  are delivered to the Trust; must be reduced  by
the  annual amortization of bond premium, if any,  on  Bonds
held   by   the  Trust;  and  must  be  increased   by   the
Certificateholder's  share  of the  accrued  original  issue
discount  with respect to each Bond which, at the  time  the
Bond was issued, had original issue discount.
     
     (v)   In  the case of any Bond held by the Trust  where
the "stated redemption price at maturity" exceeds the "issue
price", such excess shall be original issue discount.   With
respect to each Certificateholder, upon the purchase of  his
Units  subsequent to the original issuance of Bonds held  by
the  Trust,  Section 1272(a)(7) of the Code provides  for  a
reduction  in  the accrued "daily portion" of such  original
issue discount upon the purchase of a Bond subsequent to the
Bond's original issue, under certain circumstances.  In  the
case of any Bond held by the Trust the interest on which  is
excludable from gross income under Section 103 of the  Code,
any  original  issue  discount which  accrues  with  respect
thereto will be treated as interest which is excludable from
gross income under Section 103 of the Code.
     
     (vi)  Certain bonds in the portfolio of the Trust  have
been  insured by the issuers, underwriters, the  Sponsor  or
others  against default in the prompt payment  of  principal
and  interest  (the  "Insured Bonds").  Such  Bonds  are  so
designated on the portfolio pages in the Prospectus for each
Trust.   Insurance on Insured Bonds is effective so long  as
such bonds remain outstanding.  For each of these bonds,  we
have  been  advised that the aggregate principal  amount  of
such bonds listed on the portfolio page was acquired by  the
Trust and are part of the series of such bonds in the listed
aggregate principal amount.  Based upon the assumption  that
the  Insured Bonds of the Trust are part of a series covered
by  an  insurance policy, it is our opinion that any amounts
received by the Trust representing maturing interest on such
bonds  will be excludable from Federal gross income if,  and
to  the  same  extent as, such interest would have  been  so
excludable   if  paid  in  normal  course  by   the   Issuer
notwithstanding  that  the source of  the  payment  is  from
policy proceeds 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.  Paragraph  (ii)
of  this  opinion is accordingly applicable to such  payment
representing maturing interest.
     
     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 accrued to prior  owners.   The
application of these rules will also vary depending on the  value
of  the  Bond on the date a Certificateholder acquires his Units,
and the price the Certificateholder pays for his Units.
     
     Except  with  respect to those Trusts that  hold  "specified
private activity bonds" within the meaning of Section 57(a)(5) of
the  Code issued on or after August 8, 1986 as identified in  the
Prospectus related hereto (the "AMT Trusts"), the Trusts  do  not
include any specified private activity bonds and accordingly none
of  the interest income of the Trusts (other than the AMT Trusts,
if  any)  shall  be  treated as an item of  tax  preference  when
computing  the alternative minimum tax.  Because the  AMT  Trusts
include  "specified private activity bonds," all or a portion  of
the  income of the AMT Trusts shall be treated as an item of  tax
preference  for alternative minimum tax purposes in the  case  of
individuals,   trusts  and  corporations.    In   the   case   of
corporations,  for  taxable years beginning  after  December  31,
1986,  the  alternative minimum tax and the Superfund Tax  depend
upon   the  corporation's  alternative  minimum  taxable   income
("AMTI"), which is the corporation's taxable income with  certain
adjustments.
     
     Pursuant to Section 56(c) of the Code, 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) for taxable years
beginning after 1989, 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 Bonds in the Trust, and tax-exempt original issue discount.
     
     Effective for tax returns filed after December 31, 1987, all
taxpayers  are  required  to disclose  to  the  Internal  Revenue
Service the amount of tax-exempt interest earned during the year.
     
     Section  265 of the Code generally provides for a  reduction
in each taxable year of 100% of the otherwise deductible interest
on  indebtedness incurred or continued by financial institutions,
to  which  either Section 585 or Section 593 of the Code applies,
to  purchase or carry obligations acquired after August 7,  1986,
the  interest  on which is exempt from federal income  taxes  for
such  taxable year.  Under rules prescribed by Section  265,  the
amount   of  interest  otherwise  deductible  by  such  financial
institutions  in  any  taxable  year  which  is  deemed   to   be
attributable to tax-exempt obligations acquired after  August  7,
1986,  will  be  the  amount that bears the  same  ratio  to  the
interest deduction otherwise allowable (determined without regard
to  Section  265)  to the taxpayer for the taxable  year  as  the
taxpayer's average adjusted basis (within the meaning of  Section
1016)  of  tax-exempt obligations acquired after August 7,  1986,
bears  to  such  average adjusted basis for  all  assets  of  the
taxpayer,   unless  such  financial  institution  can   otherwise
establish, under regulations to be prescribed by the Secretary of
the Treasury, the amount of interest an indebtedness incurred  or
continued to purchase or carry such obligations.
     
     We  also call attention to the fact that, under Section  265
of  the  Code, interest on indebtedness incurred or continued  to
purchase or carry Units by taxpayers other than certain financial
institutions, as referred to above, is not deductible for federal
income  tax  purposes.  Under rules used by the Internal  Revenue
Service  for determining when borrowed funds are considered  used
for  the purpose of purchasing or carrying particular assets, the
purchase  of  Units  may be considered to  have  been  made  with
borrowed  funds even though the borrowed funds are  not  directly
traceable  to  the  purchase  of  Units.   However,  these  rules
generally  do not apply to indebtedness incurred for expenditures
of  a personal nature such as a mortgage incurred to purchase  or
improve a personal residence.
     
     "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  a  statutory de minimis rule.  Market  discount  can
arise  based on the price a Trust pays for Bonds or the  price  a
Certificateholder 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  Certificateholders  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 Certificateholder elects
to include market discount in taxable income as it accrues.
     
     We  hereby  consent  to the filing of  this  opinion  as  an
exhibit   to  the  Registration  Statement  (File  No.  33-61553)
relating  to the Units referred to above and to the  use  of  our
name  and  to  the  reference of our firm  in  said  Registration
Statement and in the related Prospectus.

                                                  Respectfully submitted,

     New York, New York  10003
     
     Re:  The First Trust Combined Series 251
     
     Dear Sirs:
     
     We  are  acting as special counsel with respect to New  York
tax  matters for The First Trust Combined Series 251, which  will
be  established  under a Standard Terms and Conditions  of  Trust
dated  October  16,  1991, and a related  Trust  Agreement  dated
today's   date  (collectively,  the  "Indenture"),   among   Nike
Securities  L.P.,  as  Depositor  (the  "Depositor");  Securities
Evaluation  Service,  Inc., as Evaluator;  First  Trust  Advisors
L.P., as Portfolio Supervisor and United States Trust Company  of
New  York, as Trustee (the "Trustee").  Pursuant to the terms  of
the  Indenture,  units of fractional undivided  interest  in  the
Trusts  (the "Units") will be issued in the aggregate number  set
forth in the Indenture.

We  have  examined and are familiar with originals  or  certified
copies,  or  copies otherwise identified to our satisfaction,  of
such documents as we have deemed necessary or appropriate for the
purpose of this opinion.  In giving this opinion, we have  relied
upon  the  two  opinions, each dated today and addressed  to  the
Trustee,  of Chapman and Cutler, counsel for the Depositor,  with
respect to the matters of law set forth therein.
     
     Based upon the foregoing, we are of the opinion that:
     
     1.    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.
     
     2.    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.
United States Trust Company
  of New York
     
     3.    By reason of the exemption contained in paragraph  (a)
of  Subdivision 8 of Section 270 of the New York Tax Law, no  New
York  State stock transfer tax will be payable in respect of  any
transfer of the Certificates.
     
     We  consent  to the filing of this opinion as an exhibit  to
the   Registration  Statement  (No.  33-61553)  filed  with   the
Securities   and   Exchange  Commission  with  respect   to   the
registration  of the sale of the Units and to the  references  to
our  name  under the captions "What is the Federal Tax Status  of
Unit Holders" and "Legal Opinions" in such Registration Statement
and the preliminary prospectus included therein.

            Re:  The First Trust Combined Series 251

Dear Sirs:
     
     We  are acting as counsel for United States Trust Company of
New  York  (the "Trust Company") in connection with the execution
and  delivery of a Standard Terms and Conditions of  Trust  dated
October  16,  1991, and a related Trust Agreement, dated  today's
date (collectively, the "Indenture"), among Nike Securities L.P.,
as  Depositor  (the "Depositor"); Securities Evaluation  Service,
Inc.,  as  Evaluator;  First Trust Advisors  L.P.,  as  Portfolio
Supervisor;  and  the Trust Company, as Trustee (the  "Trustee"),
establishing  The  First  Trust  Combined  Series  251,  and  the
execution  by the Trust Company, as Trustee under the  Indenture,
of a certificate or certificates evidencing ownership of units in
the aggregate number set forth in the Indenture (such certificate
or  certificates  and  such aggregate units being  herein  called
"Certificates"  and  "Units"),  each  of  which   represents   an
undivided  interest  in  the Trusts, which  consist  of  interest
bearing,  tax-exempt bonds (including confirmations of  contracts
for  the  purchase of certain bonds not yet delivered  and  cash,
cash  equivalents  or  an  irrevocable  letter  of  credit  or  a
combination  thereof, in the amount required  for  such  purchase
upon the receipt of such bonds), such bonds being defined in  the
Indenture as Bonds and listed in the Schedule or Schedules to the
Indenture.  Upon delivery of the Bonds in an Insured Trust to the
Trustee,  such  Bonds shall be insured against the nonpayment  of
principal and interest.
United States Trust Company
  of New York

     
     We have examined the Indenture, the Closing Memorandum dated
today's date and such other documents as we have deemed necessary
in  order to render this opinion.  Based on the foregoing, we are
of the opinion that:
     
     1.    The  Trust  Company is a duly organized  and  existing
corporation having the powers of a trust company under  the  laws
of the State of New York.
     
     2.    The Indenture has been duly executed and delivered  by
the Trust Company and, assuming due execution and delivery by the
other  parties thereto, constitutes the valid and legally binding
obligation of the Trust Company.
     
     3.    The Certificates are in proper form for execution  and
delivery by the Trust Company as Trustee.
     
     4.    The  Trust Company, as Trustee, has duly executed  and
delivered to or upon the order of the Depositor a Certificate  or
Certificates evidencing ownership of the Units, registered in the
name  of  the  Depositor.  Upon receipt of  confirmation  of  the
effectiveness of the registration statement for the sale  of  the
Units filed with the Securities and Exchange Commission under the
Securities  Act  of  1933, the Trustee  may  deliver  such  other
Certificates,  in such names and denominations as  the  Depositor
may request, to or upon the order of the Depositor as provided in
the Closing Memorandum.
     
     5.    The Trust Company, as Trustee, may lawfully under  the
New  York  Banking Law advance to each Trust amounts  as  may  be
necessary   to   provide   monthly  interest   distributions   of
approximately equal amounts, and be reimbursed, without interest,
for  any such advances from funds in the interest account on  the
ensuing record date, as provided in the Indenture.
     
     In  rendering the foregoing opinion, we have not considered,
among  other things, whether the Bonds have been duly  authorized
and  delivered, the efficacy of the insurance, or the federal tax
status of the Bonds.
                                    
                                    Very truly yours,

Re:  The First Trust Combined Series 251
     
     Pursuant  to your request for a Standard & Poor's rating  on
the  units of the above-captioned trust, SEC # 33-61553, we  have
reviewed  the  information presented to us and  have  assigned  a
'AAA' rating to the units of the trust and a 'AAA' rating to  the
securities contained in the trust for as long as they  remain  in
the  trust.  The ratings are direct reflections, of the portfolio
of the trust, which will be composed solely of securities covered
by  bond  insurance policies that insure against default  in  the
payment  of principal and interest on the securities so  long  as
they  remain in the trust.  Since such policies have been  issued
by one or more insurance companies which have been assigned 'AAA'
claims  paying ability ratings by S&P, S&P has assigned  a  'AAA'
rating  to the units of the trust and to the securities contained
in the trust for as long as they remain in the trust.
     
     STANDARD  & POOR'S WILL MAINTAIN SURVEILLANCE ON  THE  'AAA'
RATING  FOR A ONE YEAR PERIOD AFTER THE DATE OF DEPOSIT.  AT  THE
ONE YEAR ANNIVERSARY, THE RATING WILL BE AUTOMATICALLY TERMINATED
BY  STANDARD & POOR'S UNLESS A POST EFFECTIVE LETTER IS REQUESTED
BY THE TRUST.
     
     You  have  permission to use the name of Standard  &  Poor's
Ratings  Services, a division of The McGraw-Hill Companies,  Inc.
and   the   above-assigned  ratings  in  connection   with   your
dissemination  of information relating to these  units,  provided
that  it  is understood that the ratings are not "market" ratings
nor  recommendations to buy, hold, or sell the units of the trust
or  the securities contained in the trust.  Further, it should be
understood the rating on the units does not take into account the
extent  to which fund expenses or portfolio asset sales for  less
than  the  fund's purchase price will reduce payment to the  unit
holders of the interest and principal required to be paid on  the
portfolio  assets.   S&P reserves the right  to  advise  its  own
clients, subscribers, and the public of the ratings.  S&P  relies
on  the  sponsor and its counsel, accountants, and other  experts
for the accuracy and completeness of the information submitted in
connection  with the ratings.  S&P does not independently  verify
the truth or accuracy of any such information.
     
     This letter evidences our consent to the use of the name  of
Standard & Poor's Ratings Services, a division of The McGraw-Hill
Companies,  Inc.  in connection with the rating assigned  to  the
units in the registration statement or prospectus relating to the
units or the trust.  However, this letter should not be construed
as  a  consent  by  us, within the meaning of Section  7  of  the
Securities  Act  of 1933, to the use of the name  of  Standard  &
Poor's Ratings Services, a division of The McGraw-Hill Companies,
Inc.  in  connection with the ratings assigned to the  securities
contained in the trust.  You are hereby authorized to file a copy
of this letter with the Securities and Exchange Commission.
     
     Please  be  certain to send us three copies  of  your  final
prospectus  as  soon  as  it becomes available.   Should  we  not
receive them within a reasonable time after the closing or should
they  not  conform to the representations made to us, we  reserve
the right to withdraw the rating.
     
     We  are pleased to have had the opportunity to be of service
to  you.  If we can be of further help, please do not hesitate to
call upon us.

     Re:          The First Trust Combined Series 251;
     The First Trust of Insured Municipal Bonds-Multi-State:
                    Alabama Trust, Series 28

Gentlemen:
     
     We have acted as special Alabama tax counsel with respect to
The  First Trust Combined Series 251; The First Trust of  Insured
Municipal  Bonds-Multi-State:   Alabama  Trust,  Series  28  (the
"Fund"),  which  contains  the  Alabama  Trust,  Series  28,   an
individual  trust containing certain debt obligations  and  other
securities (the "Alabama Trust").  You have asked that we, acting
in   such  capacity,  render  an  opinion  with  respect  to  the
treatment, under the income tax laws of the State of Alabama,  of
the  Alabama  Trust  and  of the units  of  fractional  undivided
interest  therein  (the  "Units") to  be  issued  pursuant  to  a
Registration Statement on Form S-6 (the "Registration Statement")
filed   with   the   Securities  and  Exchange  Commission   (the
"Commission") under the Securities Act of 1933, as  amended  (the
"Securities Act").  You have advised us that the Alabama Trust is
created under a Trust Agreement between Nike Securities, L.P., an
Illinois limited partnership, as Sponsor, and United States Trust
Company of New York, as Trustee.
     
     In  giving our opinions set forth hereunder, we have  relied
upon  certain additional facts and conclusions provided to us  by
you,  including  the  following: (1) the Alabama  Trust  consists
solely  of  interest-bearing obligations issued by the  State  of
Alabama,   and   counties,  municipalities  or  other   political
subdivisions  thereof,  and  may  also  include  interest-bearing
obligations  issued by one or more "Possessions" (as  hereinafter
defined)  of  the United States (collectively, the  "Bonds")  the
interest on which is exempt from Federal income taxation; (2)  at
the  respective dates of issuance of the Bonds, opinions relating
to  the validity thereof and to the exemption of interest thereon
from Federal and Alabama income tax were rendered by bond counsel
to the respective issuing authority; (3) each Unit in the Alabama
Trust represents a fractional undivided interest in the principal
and  net  income of the Alabama Trust; (4) the Alabama Trust  and
any other trust included in the Fund will each be administered as
a  separate and distinct entity for all purposes, each having its
own  separate assets, accounts and certificates; (5) the  Alabama
Trust  will have no income other than interest on the  Bonds  and
gain  on the disposition of the Bonds; (6) insurance guaranteeing
the payment of all principal and interest on the obligations held
by  the Alabama Trust has been obtained by either the Sponsor  or
the  issuer or the underwriter of the respective obligations; and
(7) all of the income of the Alabama Trust will be distributed at
least semi-annually to the holders of Units ("Unit holders").
     
     In  rendering our opinion, we have relied upon,  with  yours
and  their permission, the opinion of Messrs. Chapman and  Cutler
that  for Federal income tax purposes the Alabama Trust will  not
be  classified  as an association, but will be  governed  by  the
provisions  of Subchapter J of Chapter 1 of the Internal  Revenue
Code  of  1986, as amended (the "Code"), relating to trusts.   We
have also assumed that "Possessions" of the United States as used
herein  and  in  the Registration Statement shall have  the  same
meaning as provided in the Code and that although not defined  by
Alabama  income  tax  law, regulations, or decisions,  such  term
would  be  given the same meaning for Alabama income taxation  as
provided in the Code.
     
     Based  upon, and subject to the foregoing, it is our opinion
that under existing Alabama law:
     
           1.   The Alabama Trust is not taxable as a corporation
     for purposes of the Alabama income tax.
     
           2.   Income of the Alabama Trust, to the extent it  is
     taxable,  will be taxable to the Unit holders,  not  to  the
     Alabama Trust.
     
           3.    Each  Unit holder's distributive  share  of  the
     Alabama Trust's net income will be treated as income of  the
     Unit holder for purposes of Alabama income tax.
     
           4.    Interest on obligations of the State of  Alabama
     and   subdivisions  thereof  and  on  bona  fide  tax-exempt
     obligations  of the United States' Possessions held  by  the
     Alabama  Trust which is exempt from Alabama income tax  will
     retain its tax-exempt character when the distributive  share
     thereof  is distributed or deemed distributed to  each  Unit
     holder.   Any  proceeds  paid to  the  Alabama  Trust  under
     insurance policies issued to the Sponsor or under individual
     policies  obtained by the Sponsor, the issuer or underwriter
     of  the  respective  obligations  which  represent  maturing
     interest  on defaulted obligations held by the Trustee  will
     be  exempt from Alabama income tax if and to the same extent
     as  such  interest would be exempt from such taxes  if  paid
     directly by the issuer of such obligations.
     
          5.   Each Unit holder will, for purposes of the Alabama
     income  tax, treat his distributive share of gains  realized
     upon the sale or other disposition of the Bonds held by  the
     Alabama  Trust as though the Bonds were sold or disposed  of
     directly by the Unit holder.
     
           6.    Gains  realized upon the sale or  redemption  of
     Units by Unit holders who are subject to Alabama income  tax
     will  be  includable  in the Alabama  income  of  such  Unit
     holders.
     
     We have not examined any of the Bonds to be deposited in the
Fund  or  any  legal  or  tax  opinions  rendered  in  connection
therewith,  and express no opinion as to whether the interest  on
any such Bonds is, in fact, exempt from Federal or Alabama income
taxation; nor have we made any review of the proceedings relating
to  the  issuance  of  such obligations or  the  basis  for  bond
counsel's opinions with respect thereto.
     
     We  render no opinion herein as to any fund or series of the
Trust  other than The First Trust Combined Series 251  consisting
of  The  First  Trust  of  Insured  Municipal  Bonds-Multi-State:
Alabama Trust, Series 28.
     
     We  hereby  consent  to the filing of  this  opinion  as  an
exhibit to the Registration Statement and to the reference to our
Firm  and  a  summary  of this opinion to  be  included  in  such
Registration  Statement.   In giving  this  consent,  we  do  not
thereby  admit  that  we  are in the category  of  persons  whose
consent is required by Section 7 of the Securities Act or by  the
Commission's Rules and Regulations thereunder.
                                    
                                    Very truly yours,

     Re:          The First Trust Combined Series 251
         The First Trust of Insured Municipal Bonds - Multi-
               State: Connecticut Trust, Series 15

Gentlemen:
     
     You  have  requested  that  we act  as  special  Connecticut
counsel  with respect to certain Connecticut tax aspects  of  The
First  Trust  of Insured Municipal Bonds-Multi-State: Connecticut
Trust, Series 15 (the "Connecticut Trust"), being created as part
of The First Trust Combined Series 251 (the "Fund").
     
     The  Fund is created under a Trust Agreement dated the  date
hereof  between Nike Securities L.P., as Depositor, United States
Trust  Company  of  New  York, as Trustee, Securities  Evaluation
Service,  Inc., as Evaluator, and First Trust Advisors  L.P.,  as
Portfolio  Supervisor.   The Fund will  issue  units  in  several
trusts, one of which is the Connecticut Trust.  Each unit of  the
Connecticut  Trust  (a "Unit") represents a fractional  undivided
interest  in  the  principal and net income  of  the  Connecticut
Trust.  The Connecticut Trust and any other trust included in the
Fund  will each be administered as a separate and distinct entity
for  all purposes, each having its own separate assets, accounts,
and certificates.
     
     You  have  informed us that, upon the sale of Units  of  the
Connecticut Trust to investors (the "Unit holders"),  the  assets
of the Connecticut Trust will consist of certain obligations (the
"Bonds"), some of which have been issued by or on behalf  of  the
State  of  Connecticut  or its political  subdivisions  or  other
public  bodies created under the laws of the State of Connecticut
and  the  remainder of which have been issued by or on behalf  of
entities  classified for the relevant purposes as possessions  of
the  United  States, including one or more of Puerto Rico,  Guam,
the  Virgin  Islands,  and  the  Northern  Mariana  Islands,  the
interest  on the obligations of which Federal law would  prohibit
Connecticut from taxing if received directly by the Unit holders;
that,  in the opinion of bond counsel to the issuers of  each  of
the  Bonds,  the  interest thereon is exempt from Federal  income
taxation; that distributions to Unit holders of interest received
by the Connecticut Trust and of amounts received thereby upon the
maturity,  redemption, sale, or other disposition  of  the  Bonds
will be made semi-annually except in the case of Unit holders who
have   chosen  a  monthly  distribution  period;  and  that   the
Connecticut Trust will obtain insurance guaranteeing the  payment
of  principal and interest on all Bonds when due while the  Bonds
are  held by the Connecticut Trust, except for Bonds, if any,  as
to  which  such  insurance is provided directly through  policies
obtained by the Bond issuer, the underwriters, or another person.
     
     You have further informed us that, in the opinion of Messrs.
Chapman  and  Cutler,  for Federal income tax  purposes  (i)  the
Connecticut  Trust will not be classified as an association,  but
will  be governed by the provisions of subchapter J of chapter  1
of  the  Internal Revenue Code of 1986, relating to trusts;  (ii)
pursuant to subpart E of said subchapter J, each Unit holder will
be  considered to be the owner of a portion of each asset of  the
Connecticut Trust and to have a portion of each item of income of
the  Connecticut Trust, in each case such portion being equal  to
the  part  of the whole thereof that the number of Units  of  the
Connecticut  Trust  held  by him bears to  the  total  number  of
outstanding Units of the Connecticut Trust; (iii) each such  item
of  income  will have the same character in the hands of  a  Unit
holder  as in the hands of the Trustee; (iv) such income will  be
excludable  from  a  Unit holder's Federal gross  income  to  the
extent  it consists of interest excludable therefrom for  Federal
income  tax  purposes; (v) gain or loss will be recognized  by  a
Unit holder upon the redemption or sale of his Units or upon  the
maturity,  redemption, sale, or other disposition of a Bond  held
by  the  Connecticut  Trust;  and  (vi)  any  insurance  proceeds
received  by the Connecticut Trust representing maturing interest
on  a defaulted Bond will be excludable from gross income if, and
to  the  same  extent  as,  such  interest  would  have  been  so
excludable if paid by its issuer.
     
     Based  on  the  foregoing,  and relying  explicitly  on  the
opinion  of  Messrs. Chapman and Cutler regarding Federal  income
tax   matters,  we  are  of  the  opinion  that,  under  existing
Connecticut law:
     
          1.   The Connecticut Trust is not liable for any tax on
     or   measured  by  net  income  imposed  by  the  State   of
     Connecticut.
     
          2.   Interest income from a Bond issued by or on behalf
     of  the  State  of  Connecticut, any  political  subdivision
     thereof,   or   public  instrumentality,  state   or   local
     authority, district, or similar public entity created  under
     the laws of the State of Connecticut (a "Connecticut Bond"),
     or  from  a  Bond  issued  by United States  territories  or
     possessions the interest on which Federal law would prohibit
     Connecticut  from  taxing if received  directly  by  a  Unit
     holder  from  the issuer thereof, is not taxable  under  the
     Connecticut  tax  on  the  Connecticut  taxable  income   of
     individuals,  trusts, and estates (the  "Connecticut  Income
     Tax")  when  such  interest is received by  the  Connecticut
     Trust or distributed by it to such a Unit holder.
     
           3.    Insurance  proceeds received by the  Connecticut
     Trust representing maturing interest on defaulted Bonds held
     by   the  Connecticut  Trust  are  not  taxable  under   the
     Connecticut Income Tax if, and to the same extent  as,  such
     interest would not be taxable thereunder if paid directly to
     the Connecticut Trust by the issuer of such Bonds.
     
           4.    Gains and losses recognized by a Unit holder for
     Federal  income tax purposes upon the maturity,  redemption,
     sale,  or  other disposition by the Connecticut Trust  of  a
     Bond  held  by the Connecticut Trust or upon the redemption,
     sale,  or  other  disposition of a Unit of  the  Connecticut
     Trust  held by a Unit holder are taken into account as gains
     or  losses,  respectively, for purposes of  the  Connecticut
     Income  Tax,  except  that, in the case  of  a  Unit  holder
     holding a Unit of the Connecticut Trust as a capital  asset,
     such   gains  and  losses  recognized  upon  the   maturity,
     redemption, sale, or exchange of a Connecticut Bond held  by
     the  Connecticut  Trust are excluded from gains  and  losses
     taken  into account for purposes of such tax and no  opinion
     is expressed as to the treatment for purposes of such tax of
     gains  and  losses recognized to the extent attributable  to
     Connecticut  Bonds,  upon  the redemption,  sale,  or  other
     disposition  by  a Unit holder of a Unit of the  Connecticut
     Trust held by him.
     
          5.   The portion of any interest income or capital gain
     of  the Connecticut Trust that is allocable to a Unit holder
     that is subject to the Connecticut corporation business  tax
     is  includable in the gross income of such Unit  holder  for
     purposes of such tax.
     
           6.    An  interest in a Unit of the Connecticut  Trust
     that  is  owned by or attributable to a Connecticut resident
     at  the  time of his death is includable in his gross estate
     for  purposes  of  the Connecticut succession  tax  and  the
     Connecticut estate tax.
     
     The  treatment under the Connecticut tax on the  Connecticut
taxable  income of individuals, trusts, and estates of gains  and
losses  realized by a Unit holder upon the maturity,  redemption,
sale,  or  other  disposition  by  a  Connecticut  Trust  of   an
obligation  held by it, or upon the redemption,  sale,  or  other
disposition  of  a Unit of a Connecticut Trust  held  by  a  Unit
holder  is  unclear  in  many instances.   Accordingly,  we  have
expressed  no  opinions  herein as  to  these  matters  but  have
approved  language  with  respect  thereto  to  appear   in   the
Prospectus for the Connecticut Trust.
     
     We  hereby  consent, without admitting that we  are  in  the
category  of persons whose consent is required, to the filing  of
this opinion as an exhibit to the Registration Statement relating
to  the  Units  and  to  the reference to  our  firm  as  special
Connecticut  tax counsel in such Registration Statement  and  the
Prospectus contained therein.
     
     We understand that you may deliver a copy of this opinion to
the  Trustee and hereby consent to the Trustee's relying on  this
opinion as though it were addressed to the Trustee.
                                    
                                    Very truly yours,

United States Trust Company of New York

New York, New York 10003

Gentlemen:

      We have acted as counsel to The First Trust Combined Series
251 containing The First Trust Advantage:  Idaho Trust, Series  8
(the "Trust"), with respect to certain matters preliminary to the
issuance  and  sale  of units of interest therein  (the  "Units")
pursuant to a Trust Indenture and Agreement dated as of the  date
hereof   (the  "Indenture"),  among  Nike  Securities  L.P.,   as
depositor (the "Depositor"), United States Trust Company  of  New
York,  as trustee (the "Trustee"), Securities Evaluation Service,
Inc.,  as  evaluator (the "Evaluator") and First  Trust  Advisors
L.P., as portfolio supervisor (the "Portfolio Supervisor").   The
Units  represent fractional undivided interests in the  principal
of  and  net  income on obligations deposited in one  of  several
separate  trusts, including the Trust.  Each separate trust  will
be  administered as a distinct entity with investments, expenses,
books and records.
     
     The   assets   of   the  will  consist  of  interest-bearing
obligations  issued by or on behalf of the State  of  Idaho  (the
"State") or cities and political subdivisions thereof (the "Idaho
Bonds")  and  by the Commonwealth of Puerto Rico,  Guam  and  the
United   States   Virgin   Islands   (the   "Possession   Bonds")
(collectively, the "Bonds").
     
     We  have examined the income tax law of the State, which  is
based  upon  federal law, to determine its applicability  to  the
Trust  and to the holders of Units in the Trust who are residents
of  the  State  ("Idaho Unit holders").  Although we  express  no
opinion  with respect thereto, in rendering the opinion expressed
herein  we have assumed that:  (i) the Bonds were validly issued,
(ii)  the  Idaho  Bonds meet the classification and  registration
requirements  of Idaho Income Tax Regulation 35.01.01.019,  (iii)
the  interest  on the Bonds is excludable from gross  income  for
federal income tax purposes and (iv) the interest on the Bonds is
exempt from taxation under the provisions of the Idaho Income Tax
Act  (the "Idaho income tax").  The opinion set forth below  does
not   address  the  taxation  of  persons  other  than  full-time
residents  of Idaho.  Based on the foregoing, it is  our  opinion
that  under  Idaho  income  tax law,  as  presently  enacted  and
construed:

       (1)   The  Trust  is  not  an  association  taxable  as  a
corporation  for Idaho income tax purposes, and each Unit  holder
of  the  Trust will be treated as the owner of a pro rata portion
of the assets held by the Trust and the income of such portion of
the  Trust  will be treated as the income of the Unit holder  for
Idaho income tax purposes.

      (2)   Income  on the Bonds which is exempt from  the  Idaho
income  tax when received by the Trust, and which would be exempt
from  the Idaho income tax if received directly by a Unit holder,
will  retain its status as exempt from such tax when received  by
the Trust and distributed to such Unit holder.

      (3)   To  the extent that interest income derived from  the
Trust  by  a  Unit  holder with respect to  Possession  Bonds  is
excludable  from  gross income for federal  income  tax  purposes
pursuant to 48 U.S.C. Section 745, 48 U.S.C. Section 1423a or  48
U.S.C. Section 1403, such interest income will not be subject  to
the Idaho income tax.

      (4)   In  general, each Unit holder will recognize gain  or
loss  for Idaho income tax purposes if the Trustee disposes of  a
Bond  (whether by redemption, sale or otherwise) or if  the  Unit
holder  redeems  or sells Units of the Trust to the  extent  that
such  a transaction results in a recognized gain or loss to  such
Unit  holder  for  federal income tax purposes.   However,  Idaho
income tax law may prevent a Unit holder from taking a recognized
loss  into  account for Idaho income tax purposes, under  certain
circumstances.

      (5)   The Idaho income tax does not permit a deduction  for
interest  paid  on  indebtedness incurred or continued  to  carry
Units in the Trust to the extent that interest income related  to
the ownership of Units is exempt from the Idaho income tax.

      (6)   Any  insurance  proceeds paid  under  policies  which
represent  maturing interest on defaulted obligations  which  are
excludable from gross income for federal income tax purposes will
be  excludable  from the Idaho income tax to the same  extent  as
such interest would have been so excludable if paid by the issuer
of  such Bonds held by the Trust 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.

      Units may be subject to the Idaho estate and transfer  tax.
Idaho  has  special  rules  regarding  a  taxpayer's  ability  to
recognize capital losses that apply in certain cases.

      We  have not examined any of the Bonds to be deposited  and
held in the Trust or the proceedings for the issuance thereof  or
the  opinions of bond counsel with respect thereto, and therefore
express no opinion as to the exemption from the Idaho income  tax
of interest on the Bonds if received directly by a Unit holder.

      We  hereby  consent  to the filing of this  opinion  as  an
exhibit  to  the  Registration  Statement  (No.  33-61553)  filed
pursuant  to the Securities Act of 1933, as amended (the  "Act"),
with respect to the registration of the sale of the Units and  to
the references to our firm in such Registration Statement and the
preliminary prospectus included therein.  In giving such consent,
we  do  not  thereby admit that we are persons whose  consent  is
