        THE MUNICIPAL BOND TRUST, SERIES 224
              THE MUNICIPAL BOND TRUST,
            CALIFORNIA INSURED, SERIES 7A

This Prospectus consists of two parts. Part A 
contains Essential Information Regarding the 
Trusts including descriptive material relating 
to the Trusts, Financial Statements of the 
Trusts, and Schedules of Investments. Part B 
contains general information about the Trusts. 
Part A may not be distributed unless accompanied 
by Part B. 

Interest income to the Trusts and to 
Certificateholders is excludable, in
the opinion of counsel, from gross income  12,126
for Federal income tax purposes and exempt  UNITS
from California income taxes for resident
purchasers of the Municipal Bond Trust,
California Insured, Series 7A, under 
existing law, but may be subject to state
and local taxation. Capital gains, if any,
are subject to tax.

THE INITIAL PUBLIC OFFERING OF UNITS IN THE 
TRUST HAS BEEN COMPLETED. THE UNITS OFFERED 
HEREBY ARE ISSUED AND OUTSTANDING UNITS WHICH 
HAVE BEEN ACQUIRED BY THE SPONSOR EITHER BY 
PURCHASE FROM THE TRUSTEE OF UNITS TENDERED FOR 
REDEMPTION OR IN THE SECONDARY MARKET.
THE OBJECTIVES OF THE MUNICIPAL BOND TRUST, 
SERIES 224 AND THE MUNICIPAL BOND TRUST, 
CALIFORNIA INSURED, SERIES 7A-The Municipal Bond 
Trust, Series 224 ("Series 224") and The 
Municipal Bond Trust, California Insured, Series 
7A (the "California Insured Trust") are two 
separate unit investment trusts formed for the 
purpose of gaining Federally tax-exempt interest 
income consistent with the preservation of 
capital and diversification of risk through 
investment in a fixed portfolio of "investment 
grade" (as of the Initial Date of Deposit) 
interest-bearing municipal bonds (the "Bonds"). 
The payment of interest and the preservation of 
capital is dependent upon the continuing ability 
of the respective issuers of such Bonds to meet 
their obligations. Since PaineWebber 
Incorporated (the "Sponsor") and Investors Bank 
and Trust Company and The First National Bank of 
Chicago (the "Co-Trustees") do not have control 
over the source of payment of the Bonds, they 
cannot guarantee that the objectives of the 
Trust will be achieved. Each Trust will be 
administered as a distinct entity with separate 
certificates, expenses, books and records. 

Each Unit of each Trust represents a fractional 
undivided interest in the principal amount of 
the underlying bonds and net income of such 
Trust in the ratio of 1 Unit for each $922.98 
and $993.72 principal amount of underlying bonds 
deposited in Series 224 and the California 
Insured Trust, respectively.

                          Units Principal Amount
Series 224                7,985       $7,370,000
California Insured Series 7A  4,141   $4,115,000

PUBLIC OFFERING PRICE-The Public Offering Price 
of Units is equal to the aggregate of the bid 
prices of the underlying Bonds divided by the 
number of Units outstanding plus a sales charge 
of up to 5.82% of the net amount invested (5.50% 
of the Public Offering Price). Units are offered 
at the Public Offering Price plus accrued 
interest. (See "Public Offering Price of Units" 
and "Secondary Market for Units" in Part B). 

MARKET FOR UNITS-Although under no obligation to 
do so, the Sponsor intends to maintain a market 
for Units at prices based on the aggregate bid 
price of the Bonds in the Trust. If such market 
is terminated, a Certificateholder may be able 
to dispose of his Units only through redemption 
(see "Secondary Market for Units" in Part B). 
Investors should note that the terms 
"Certificateholders" and "Unitholders" are used 
interchangeably in this prospectus.

DISTRIBUTIONS-Distributions of interest received 
by the Trust, less expenses, will be made on a 
monthly basis. See "Distribution to Unitholders" 
in Part B for details of distributions. 

ESTIMATED CURRENT RETURN-The Estimated Current 
Return per Unit is determined by dividing the 
net annual interest income per Unit by the 
Public Offering Price per Unit. Any change in 
either amount will result in a change in 
Estimated Current Return (see "Estimated Current 
Return and Estimated Long Term Return" in Part B 
and "Essential Information" in Part A).

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

ESSENTIAL INFORMATION REGARDING THE TRUSTS
Securities in the Trust Portfolios 
 Each of the Trusts consists of the Securities 
indicated under "Schedule of Investments", all 
undistributed interest received or accrued on the 
Securities, and any undistributed cash realized 
from the sale, redemption or other disposition of 
the Securities. All of the Bonds in the Trusts 
were, as of the Initial Date of Deposit, 
"investment grade" municipal bonds. 

 The aggregate market values of the Bonds in 
each Trust as of December 31, 1997, based on the 
bid side of the market, were as follows:

Insurance
 All of the Bonds in the California Insured 
Trust are insured as to scheduled payment of 
interest and principal. In the event the issuer 
of these bonds defaults, the insurance company 
insuring the bond would be required to pay to 
the Trustee any interest or principal payments 
due. The Bonds in the Trust are insured by the 
following insurers (See "Insurance on the Bonds 
in the Portfolio" in Part B for a description of 
each of the Insurers):

for a summary of the Investment risks associated 
with the Securities contained in the Trust.

SPECIAL CONSIDERATIONS REGARDING CALIFORNIA 
SECURITIES
 The financial condition of the State of 
California (the "State"), its public authorities 
and local governments could affect the market 
values and marketability of, and therefore the 
net asset value per share and the interest 
income of, the Portfolio, or result in the 
default of existing obligations, including 
obligations which may be held by the Portfolio. 
The following section provides only a brief 
summary of the complex factors affecting the 
financial condition of California, and is based 
on information obtained from the State, as 
publicly available on the date of this 
Prospectus. The information contained in such 
publicly available documents has not been 
independently verified. It should be noted that 
the creditworthiness of obligations issued by 
local issuers may be unrelated to the 
creditworthiness of obligations issued by the 
State, and that there is no obligation on the 
part of the State to make payment on such local 
obligations in the event of default in the 
absence of a specific guarantee or pledge 
provided by the State. 
 During the early 1990's, California experienced 
significant financial difficulties, which 
reduced its credit standing, but the State's 
finances have improved since 1994.  The ratings 
of certain related debt of other issuers for 
which California has an outstanding lease 
purchase, guarantee or other contractual 
obligation (such as for state-insured hospital 
bonds) are generally linked directly to 
California's rating.  Should the financial 
condition of California deteriorate again, its 
credit ratings could be further reduced, and the 
market value and marketability of all 
outstanding notes and bonds issued by 
California, its public authorities or local 
governments could be adversely affected.

Economic Factors
 California's economy is the largest among the 
50 states and one of the largest in the world.  
The State's population of more than 32.9 million 
represents over 12% of the total United States 
population and grew by 27% in the 1980s.  Total 
personal income in the State, at an estimated 
$760 billion in 1995, accounts for almost 13% of 
all personal income in the nation.  Total 
employment is over 14 million, the majority of 
which is in the service, trade and manufacturing 
sectors.
 From mid-1990 to late 1993, the State suffered 
a recession with the worst economic, fiscal and 
budget conditions since the 1930s, with over 
700,000 jobs lost.  The worst job losses were, 
in Southern California, led by declines in the
aerospace and construction industries, and
significantly related to cuts in federal defense
spending. Since the start of 1994, the California
economy has been in a steady recovery in all parts
of the State.  The State Department of Finance has 
reported strong net job growth, particularly in 
construction, high technology and electronic 
manufacturing and services, wholesale and retail 
trade, exports, entertainment and tourism.  
Prerecession job levels were reached in 1996, 
and have been growing since then at faster than 
the national average rate. Unemployment is down 
to half the rate of the recession peak, but 
still remains higher than the national average.  
The Asian economic crisis is expected to have 
some moderating effect on the State's economy, 
as exports to the region will be reduced, but 
there are also expected to be some offsetting 
factors, and State exports to other areas, like 
Latin America, have been growing rapidly. 

Constitutional Limitations on Taxes, Other 
Charges and Appropriations
 Limitation on Property Taxes.  Certain 
California Municipal Obligations may be 
obligations of issuers which rely in whole or in 
part, directly or indirectly, on ad valorem 
property taxes as a source of revenue.  The 
taxing powers of California local governments 
and districts are limited by Article XIIIA of 
the California Constitution, enacted by the 
voters in 1978 and commonly known as 
"Proposition 13."  Briefly, Article XIIIA limits 
to 1% of full cash value of the rate of ad 
valorem property taxes on real  property and 
generally restricts the reassessment of property 
to 2% per year, except under new construction or 
change of ownership (subject to a number of 
exemptions).  Taxing entities may, however, 
raise ad valorem taxes above the 1% limit to pay 
debt service on voter-approved bonded 
indebtedness.
 Under  Article XIIIA, the basic 1% ad valorem 
tax levy is applied against the assessed value 
of property as of the owner's date of 
acquisition (or as of March 1, 1975, if acquired 
earlier), subject to certain adjustments.  This 
system has resulted in widely varying amounts of 
tax on similarly situated properties.  Several 
lawsuits have been filed challenging the 
acquisition-based assessment system of 
Proposition 13, but it was upheld by the U.S. 
Supreme Court in 1992.
 Article XIIIA prohibits local governments from 
raising revenues through ad valorem taxes above 
the 1% limit; it also requires voters of any 
governmental unit to give two-thirds approval to 
levy and "special tax." Court decisions, 
however, allowed a non-voter approved levy of 
"general taxes" which were not dedicated to a 
specific use.  
 Limitations on Other Taxes, Fees and Charges.  
On November 5, 1996, the voters of the State 
approved Proposition 218, called the "Right to 
Vote on Taxes Act."  Proposition 218 added 
Articles XIIIC and XIIID to the State 
Constitution, which contain a number of 
provisions affecting the ability of local 
agencies to levy and collect both existing and 
future taxes, assessments, fees and charges.
 Article XIIIC requires that all new or 
increased local taxes be submitted to the 
electorate before they become effective.  Taxes 
for general governmental purposes require a 
majority vote and taxes for specific purposes 
require a two-thirds vote.  Further, any general 
purpose tax which was imposed, extended or 
increased without voter approval after December 
31, 1994 must be approved by a majority vote 
within two years.
 Article XIIID contains several new provisions 
making it generally more difficult for local 
agencies to levy and maintain "assessments" for 
municipal services and programs.  Article XIIID 
also contains several new provisions affecting 
"fees" and "charges", defined for purposes of 
Article XIIID to mean "any levy other than an ad 
valorem tax, a special tax, or an assessment, 
imposed by a [local government] upon a parcel or 
upon a person as an incident of property 
ownership, including a user fee or charge for a 
property related service."  All new and existing 
property related fees and charges must conform 
to requirements prohibiting, among other things, 
fees and charges which generate revenues 
exceeding the funds required to provide the 
property related service or are used for 
unrelated purposes.  There are new notice, 
hearing and protest procedures for levying or  
increasing property related fees and charges, 
and, except for fees or charges for sewer, water 
and refuse collection services (or fees for 
electrical and gas service, which are not 
treated as "property related" for purposes of 
Article XIIID), no property related fee or 
charge may be imposed or increased without 
majority approval by the property owners subject 
to the fee or charge or, at the option of the 
local agency, two-thirds voter approval by the 
electorate residing in the affected area.
 In addition to the provisions described above, 
Article XIIIC removes limitations on the 
initiative power in matters of local taxes, 
assessments, fees and charges.  Consequently, 
local voters could, by future initiative, 
repeal, reduce or prohibit the future imposition 
or increase of any local tax, assessment, fee or 
charge.  It is unclear how this right of local 
initiative may be used in cases where taxes or 
charges have been or will be specifically 
pledged to secure debt issues.
 The interpretation and application of 
Proposition 218 will ultimately be determined by 
the courts with respect to a number of matters, 
and it is not possible at this time to predict 
with certainty, the outcome of such 
determinations.  Proposition 218 is generally 
viewed as restricting the fiscal flexibility of 
local governments, and for this reason, some 
ratings of California cities and counties have 
been, and others may be, reduced.
 Appropriations Limits.  The State and its local 
governments are subject to an annual 
"appropriations limit" imposed by Article XIIIB 
of the California Constitution, enacted by the 
voters in 1979 and significantly amended by 
Propositions 98 and 111 in 1988 and 1990, 
respectively.  Article XIIIB prohibits the State 
or any covered local government from spending 
"appropriations subject to limitation" in excess 
of the appropriations limit imposed.  
"Appropriations subject to limitation" are 
authorizations to spend "proceeds of taxes," 
which consist of tax revenues and certain other 
funds, including proceeds from regulatory 
licenses, user charges or other fees, to the 
extent that such proceeds exceed the cost of 
providing the product or service, but "proceeds 
of taxes" exclude most State subventions to 
local governments.  No limit is imposed on 
appropriations of funds which are not "proceeds 
of taxes," such as reasonable user charges or 
fees, and certain other non-tax funds, including 
bond proceeds.
 Among the expenditures not included in Article 
XIIIB appropriations limit are (1) the debt 
service cost of bonds issued or authorized prior 
to January 1, 1979, or subsequently authorized 
by voters, (2) appropriations arising from 
certain emergencies declared by the Governor, 
(3) appropriations for certain capital outlay 
projects, (4) appropriations by the State of 
post-1989 increases in gasoline taxes and 
vehicle weight fees, and (5) appropriations made 
in certain cases of emergency.
 The appropriations limit for each year is 
adjusted annually to reflect changes in cost of 
living and population, and any transfers of 
service responsibilities between government 
units.  The definitions for such adjustments 
were liberalized in 1990 to follow more closely 
growth in the State's economy.  
 "Excess" revenues are measured over a two year 
cycle.  Local governments must return any excess 
to taxpayers by rate reductions.  The State must 
refund 50% of any excess, with the other 50% 
paid to schools and community colleges.  With 
more liberal annual adjustment factors since 
1988, and depressed revenues since 1990 because 
of the recession, few governments are currently 
operating near their spending limits, but this 
condition may change over time.  Local 
governments may by voter approval exceed their 
spending limits for up to four years.  State 
appropriations were more than $6.0 billion under 
the limit for fiscal year 1997-98.
 Because of the complex nature of Articles 
XIIIA, XIIIB, XIIIC and XIIID of the California 
Constitution, the ambiguities and possible 
inconsistencies in their terms, and the 
impossibility of predicting future 
appropriations or changes in population and cost 
of living, and the probability of continuing 
legal challenges, it is not currently possible 
to determine fully the impact of these Articles 
on California Municipal Obligations or on the 
ability of the State or local governments to pay 
debt service on such California Municipal 
Obligations.  It is not possible, at the present 
time, to predict the outcome  of any pending 
litigation with respect to the ultimate scope, 
impact or constitutionality of these Articles or 
the impact of any such determinations upon State 
agencies or local governments, or upon their 
ability to pay debt service on their 
obligations.  Further initiatives or legislative 
changes in laws or the California Constitution 
may also affect the ability of the State or 
local issuers to repay their obligations.

Obligations of the State of California.
 Under the California Constitution, debt service 
on outstanding general obligation bonds is the 
second charge to the General Fund after support 
of the public school system and public 
institutions of higher education.  As of 
February 1, 1998, the State had outstanding 
approximately $18.5 billion of long-term general 
obligation bonds, plus $1.051 billion of general 
obligation commercial paper which will be 
refunded by long-term bonds in the future, and 
$6.4 billion of lease-purchase debt supported by 
the State General Fund.  The State also had 
about $9 billion of authorized and unissued 
general obligation bonds and lease-purchase 
debt.  In FY 1996-97, debt service on general 
obligation bonds and lease purchase debt was 
approximately 5.0% of General Fund revenues.

Recent Financial Results.
 The principal sources of General Fund revenues 
in 1996-1997 were the California personal income 
tax (47% of total revenues), the sales tax 
(34%), and bank and corporation taxes (12%).  
The State maintains a Special Fund for Economic 
Uncertainties (the "SFEU"), derived from General 
Fund revenues, as a reserve to meet cash needs 
of the General Fund, but which is required to be 
replenished as soon as sufficient revenues are 
available.  Year-end balances in the Economic 
Uncertainties Fund are included for financial 
reporting purposes in the General Fund balance.
 General.  Throughout the 1980's, State spending 
increased rapidly as the State population and 
economy also grew rapidly, including increased 
spending for many assistance programs to local 
governments, which were constrained by 
Proposition 13 and other laws.  The largest 
State program is assistance to local public 
school districts.  In 1988, an initiative 
(Proposition 98) was enacted which (subject to 
suspension by a two-thirds vote of the 
Legislature and the Governor) guarantees local 
school districts and community college districts 
a minimum share of State General Fund revenues 
(currently about 35%).
 Since the start of the 1990-91 fiscal year, the 
State has faced adverse economic, fiscal, and 
budget conditions.  The economic recession 
seriously affected State tax revenues.  It also 
caused increased expenditures for health and 
welfare programs.
 Recent Budgets.  As a result of these factors, 
among others, from the late 1980's until 1992-
93, the State had a period of nearly chronic 
budget imbalance, with expenditures exceeding 
revenues in four out of six years, and the State 
accumulated and sustained a budget deficit in 
the SFEU approaching $2.8 billion at its peak at 
June 30, 1993.  For several years, each budget 
required multibillion dollar actions to bring 
projected revenues and expenditures into balance 
and to close large "budget gaps" which were 
identified.  The Legislature and Governor 
eventually agreed on a number of different steps 
to produce Budget Acts in the Years 1991-92 to 
1995-96, (although not all of these actions were 
taken in each year):

 * significant cuts in health and welfare 
program expenditures;
 * transfers of program responsibilities and 
some funding sources from the State to local
  governments, coupled with some reduction in 
mandates on local government;
 * transfer of about $3.6 billion in annual 
local property tax revenues from cities, 
counties,
  redevelopment agencies and some other 
districts to local school districts, thereby 
reducing State
  funding for schools;
 * reduction in growth of support for higher 
education programs, couples with increases in 
student
  fees;
 * revenue increases (particularly in the 1992-
93 Fiscal Year budget), most of which were for a 
short
  duration;
 * increased reliance on aid from the federal 
government to offset the costs of incarcerating,
  educating and providing health and welfare 
services to undocumented aliens (although these
  efforts have produced much less federal aid 
than the State Administration had requested); 
and 
 * various one-time adjustment and accounting 
changes.

 The combination of stringent budget actions 
cutting State expenditures, and the turnaround 
of the economy by late 1993, finally led to the 
restoration of positive financial results, with 
revenues equaling or exceeding expenditures 
starting in FY 1992-93.  As a result, the 
accumulated budget deficit of about $2.8 billion 
was eliminated by June 30, 1997, when the State 
showed a positive balance of about $408 million, 
on a budgetary basis, in the SFEU.
 A consequence of the accumulated budget 
deficits in the early 1990's, together with 
other factors such as disbursement of funds to 
local school districts "borrowed" from future 
fiscal years and hence not shown in the annual 
budget, was to significantly reduce the State's 
cash resources available to pay its ongoing 
obligations.  The State's cash condition became 
so serious that from late spring 1992 until 
1995, the State had to rely on issuance of short 
term notes which matured in a subsequent fiscal 
year to finance its ongoing deficit, and pay 
current obligations.  For a two-month period in 
the summer of 1992, pending adoption of the 
annual Budget Act, the State was forced to issue 
registered warrants (IOUs) to some of its 
suppliers, employees and other creditors. The 
last of these deficit notes was repaid in April, 
1996.
 The 1995-96 and 1996-97 Budget Acts reflected 
significantly improved financial conditions, as 
the State's economy recovered and tax revenues 
soared above projections.  Over the two years, 
revenues averaged about $2 billion higher than 
initially estimated.  Most of the additional 
revenues were allocated to school funding, as 
required by Proposition 98, and to make up 
shortfalls in federal aid for health and welfare 
costs and costs of illegal aliens.  The budgets 
for both these years showed strong increases in 
funding for K-14 public education, including 
implementation of initiatives to reduce class 
sizes for lower elementary grades to not more 
than 20 pupils.  Higher education funding also 
increased.  Spending for health and welfare 
programs was kept in check, as previously-
implemented cuts in benefit levels were 
retained.  
 The final results for FY 1996-97 showed General 
Fund revenues of $49.2 billion and expenditures 
of $48.9 billion.  The improved revenues allowed 
the repayment of the last of the recession-
induced budget deficits; the SFEU had a balance 
of $408 million on a budgetary basis ($281 
million on a cash basis) as of June 30, 1997, 
the first significant positive balance in the 
decade.  In 1996-97, the State implemented its 
regular cash flow borrowing program with the 
issuance of $3.0 billion of Revenue Anticipation 
Notes which matured on June 30, 1997, and did 
not require any external borrowing over the end 
of the fiscal year.  
 Fiscal Year 1997-98 Budget.  With continued 
strong economic recovery and surging tax 
receipts, the State entered the 1997-98 Fiscal 
Year in the strongest financial position in the 
decade.  However, in May 1997, the California 
Supreme Court ruled that the State had acted 
illegally in 1993 and 1994 by using a deferral 
of payments to the Public Employees Retirement 
Fund to help balance earlier budgets.  In 
response to this court decision, the Governor 
ordered an immediate repayment to the Retirement 
Fund of about $1.235 billion, which was made in 
late July, 1997, and substantially "used up" the 
expected additional revenues for the fiscal 
year.  
 On August 18, 1997, the Governor signed the 
1997-98 Budget Act.  The Budget Act assumed 
General Fund revenues and transfers of $52.5 
billion, and contained expenditures of $52.8 
billion.  As a result, the budget reserve (SFEU) 
was reduced to an estimated $112 million at June 
30, 1998.  The Budget Act also contains $14.4 
billion of Special Fund expenditures.  Following 
enactment of the Budget Act, the State carried 
out its normal annual cash flow borrowing, 
totaling $3.0 billion to mature June 30, 1998.
 The 1997-98 Budget Act provided another year of 
rapidly increasing funding for K-14 public 
education.  Total General Fund support will 
reach $5,150 per pupil, more than 20% higher 
than the recession-period levels which were in 
effect as late as FY 1993-94.  The $1.75 billion 
in new funding will be spent on class size 
reduction and other initiatives, as well as 
fully funding growth and cost of living 
increases.  Support for higher education units 
in the State also increased by about 6 percent.  
Because of the pension payment, most other State 
programs were funded at levels consistent with 
prior years, and several initiatives had to be 
dropped.  These included additional assistance 
to local governments, state employee raises, and 
funding of a bond bank.
 Part of the 1997-98 Budget Act was completion 
of State welfare reform legislation to implement 
the new federal law passed in 1996.  The new 
State program, called "CalWORKs," became 
effective January 1, 1998, will emphasize 
programs to bring aid recipients into the 
workforce.  As required by federal law, new time 
limits will be placed on receipt of welfare aid.  
Grant levels for 1997-98 remain at the reduced, 
prior years' levels.
 Although, as noted, the 1997-98 Budget Act 
projects a budget reserve in the SFEU of $112 
million on June 30, 1998, the General Fund fund 
balance on that date also reflects $1.25 billion 
of "loans" which the General Fund made to local 
schools in the recession years, representing 
cash outlays above the mandatory minimum funding 
level.  Settlement of litigation over these 
transactions in July 1996 calls for repayment of 
these loans over the period ending in 2001-02, 
about equally split between outlays from the 
General Fund and from schools' entitlements.  
The 1997-98 Budget Act contained a $200 million 
appropriation from the General Fund toward this 
settlement
 Updated figures from the Department of Finance, 
released in early January, 1998, project both 
revenues and expenditures will be higher in 
1997-98 than estimated when the Budget Act was 
passed, reflecting continued strong economic 
activity.  The Department projects the budget 
reserve (SFEU) at June 30, 1998 will be 
approximately $329 million.
 Proposed 1998-99 Fiscal Year Budget.  The 
Governor released his proposed FY 1998-99 Budget 
on January 9, 1998.  It projected General Fund 
revenues and transfers of $55.4 billion, an 
increase of almost 5% over 1997-98.  Revenue 
losses due to tax cuts enacted in late 1997 were 
expected to be offset by higher capital gains 
realizations.  The Governor proposed 
expenditures of $55.4 billion, also an almost 5% 
increase from the prior year.  The Governor's 
Budget proposes significant additional funding 
for K-12 schools under Proposition 98, as well 
as additional funding for higher education, with 
a proposed reduction of college student fees.  
State and federal funds will be used in the new 
CalWORKS welfare program, with projections of a 
fourth consecutive year or caseload decline.  
The Governor has proposed a large capital 
expenditure program, focusing on schools and 
universities, but also including corrections, 
environmental and general government projects.  
These proposals would require approval of almost 
$10 billion of new general obligation bonds over 
the next six years.  All of the Governor's 
proposals will be reviewed by the Legislature as 
part of the annual budget process.
 Although the State's strong economy is 
producing record revenues to the State 
government, the State's budget continues to be 
under stress from mandated spending on 
education, a rising prison population, and 
social needs of a growing population with many 
immigrants.  These factors which limit State 
spending growth also put pressure on local 
governments.  There can be no assurances that, 
if economic conditions weaken, or other factors 
intercede, the State will not experience budget 
gaps in the future.

Bond Rating
 The ratings on California's long-term general 
obligation bonds were reduced in the early 
1990's from "AAA" levels which had existed prior 
to the recession, but have been raised since 
1996.  As of April 1998 California's general 
obligation bonds were assigned ratings of "A+" 
from Standard & Poor's, "A1" from Moody's and 
"AA-" from Fitch.
 There can be no assurance that such ratings 
will be maintained in the future.  It should be 
noted that the creditworthiness of obligations 
issued by local California issuers may be 
unrelated to creditworthiness of obligations 
issued by the State of California, and that 
there is no obligation on the part of the State 
to make payment on such local obligations in the 
event of default.

Legal Proceedings
 The State is involved in certain legal 
proceedings (described in the State's recent 
financial statements) that, if decided against 
the State, may require the State to make 
significant future expenditures or may 
substantially impair revenues.  Trial courts 
have recently entered tentative decisions or 
injunctions which would overturn several parts 
of the State's recent budget compromises.  The 
matters covered by these lawsuits include a 
deferral of payments by California to the Public 
Employees Retirement System, reductions in 
welfare payments and the use of certain 
cigarette tax funds for health costs.  All of 
these cases are subject to further proceedings 
and appeals, and if California eventually loses, 
the final remedies may not have to be 
implemented in one year.

Obligations Of Other Issuers
 Other Issuers of California Municipal 
Obligations.  There are a number of State 
agencies, instrumentalities and political 
subdivisions of the State that issue Municipal 
Obligations, some of which may be conduit 
revenue obligations payable from payments from 
private borrowers.  These entities are subject 
to various economic risks and uncertainties, and 
the credit quality of the securities issued by 
them may vary considerably from the credit 
quality of obligations backed by the full faith 
and credit of the State.
 State Assistance.  Property tax revenues 
received by local governments declined more than 
50% following passage of Proposition 13.  
Subsequently, the California Legislature enacted 
measures to provide for the redistribution of 
the State's General Fund surplus to local 
agencies, the reallocation of certain State 
revenues to local agencies and the assumption of 
certain governmental functions by the State to 
assist municipal issuers to raise revenues.  
Total local assistance from the State's General 
Fund was budgeted at approximately 75% of 
General Fund expenditures in recent years, 
including the effect of implementing reductions 
in certain aid programs.  To reduce State 
General Fund support for school districts, the 
1992-93 and 1993-94 Budget Acts caused local 
governments to transfer $3.9 billion of property 
tax revenues to school districts, representing 
loss of the post-Proposition 13 "bailout" aid.  
Local governments have in return received 
greater revenues and greater flexibility to 
operate health and welfare programs.  To the 
extent the State should be constrained by its 
Article XIIIB appropriations limit, or its 
obligation to conform to Proposition 98, or 
other fiscal considerations, the absolute level, 
or the rate of growth, of State assistance to 
local governments may continue to be reduced.  
Any such reductions in State aid could compound 
the serious fiscal constraints already 
experienced by many local governments, 
particularly counties.  At least one rural 
county (Butte) publicly announced that it might 
enter bankruptcy proceedings in August 1990, 
although such plans were put off after the 
Governor approved legislation to provide 
additional funds for the county.  Other counties 
have also indicated that their budgetary 
condition is extremely grave.  Los Angeles 
County, the largest in the State, was forced to 
make significant cuts in services and personnel, 
particularly in the health care system, in order 
to balance its budget in 1995-96 and 1996-97.  
Los Angeles County's debt was downgraded by 
Moody's and S&P in the summer of 1995.  Orange 
County, which emerged from Federal Bankruptcy 
Court protection in June 1996, has significantly 
reduced county services and personnel, and faces 
strict financial conditions following large 
investment fund losses in 1994 which resulted in 
bankruptcy.
 Counties and cities may face further budgetary 
pressures as a result of changes in welfare and 
public assistance programs, which were enacted 
in August, 1997 in order to comply with the 
federal welfare reform law.  Generally, counties 
play a large role in the new system, and are 
given substantial flexibility to develop and 
administer programs to bring aid recipients into 
the workforce.  Counties are also given 
financial incentives if either at the county or 
statewide level, the "Welfare-to-Work" programs 
exceed minimum targets; counties are also 
subject to financial penalties for failure to 
meet such targets.  Counties remain responsible 
to provide "general assistance" for able-bodied 
indigents who are ineligible for other welfare 
programs.  The long-term financial impact of the 
new CalWORKs system on local governments is 
still unknown.
 Legislation enacted in late 1997 provides for 
the State to take over financial responsibility 
for funding trial courts throughout the State.  
This is estimated to save counties and cities a 
total of over $350 million annually.
 Assessment Bonds. California Municipal 
Obligations which are assessment bonds may be 
adversely affected by a general decline in real 
estate values or a slowdown in real estate sales 
activity.  In many cases, such bonds are secured 
by land which is undeveloped at the time of 
issuance but anticipated to be developed within 
a few years after issuance. In the event of such 
reduction or slowdown, such development may not 
occur or may be delayed, thereby increasing the 
risk of a default on the bonds.  Because the 
special assessments or taxes securing these 
bonds are not the personal liability of the 
owners of the property assessed, the lien on the 
property is the only security for the bonds.  
Moreover, in most cases the issuer of these 
bonds is not required to make payments on the 
bonds in the event of delinquency in the payment 
of assessments or taxes, except from amounts, if 
any, in a reserve fund established for the 
bonds.
 California Long Term Lease Obligations.  Based 
on a series of court decisions, certain long-
term lease obligations, though typically payable 
from the general fund of the State or a 
municipality are not considered "indebtedness" 
requiring voter approval.  Such leases, however, 
are subject to "abatement" in the event the 
facility being leased is unavailable for 
beneficial use and occupancy by the municipality 
during the term of the lease.  Abatement is not 
a default, and there may be no remedies 
available to the holders of the certificates 
evidencing the lease obligation in the event 
abatement occurs.  The most common cases of 
abatement are failure to complete construction 
of the facility before the end of the period 
during which lease payments have been 
capitalized and uninsured casualty losses to the 
facility (e.g., due to earthquake).  In the 
event abatement occurs with respect to a lease 
obligation, lease payments may be interrupted 
(if all available insurance proceeds and 
reserves are exhausted) and the certificates may 
not be paid when due.  Litigation is brought 
form time to time which challenges the 
constitutionality of such lease arrangements.

Other Considerations
 The repayment of industrial development 
securities secured by real property may be 
affected by California laws limiting foreclosure 
rights of creditors.  Securities backed by 
health care and hospital revenues may be 
affected by changes in State regulations 
governing cost reimbursements to health care 
providers under Medi-Cal (the State's Medicaid 
program), including risks related to the policy 
of awarding exclusive contracts to certain 
hospitals.
 Limitations on ad valorem property taxes may 
particularly affect "tax allocation": bonds 
issued by California redevelopment agencies.  
Such bonds are secured solely by the increase in 
assessed valuation of a redevelopment project 
area after the start of redevelopment activity.  
In the event that assessed values in the 
redevelopment project decline (e.g., because of 
a major natural disaster such as an earthquake), 
the tax increment revenue may be insufficient to 
make principal and interest payments on these 
bonds.  Both Moody's and S&P suspended ratings 
on California tax allocation bonds after the 
enactment of Articles XIIIA and XIIIB, and only 
resumed such ratings on a selective basis.
 Proposition 87, approved by California voters 
in 1988, requires that all revenues produced by 
a tax rate increase go directly to the taxing 
entity which increased such tax rate to repay 
that entity's general obligation indebtedness.  
As a result, redevelopment agencies (which, 
typically, are the issuers of tax allocation 
securities) no longer receive an increase in tax 
increment when taxes on property in the project 
area are increased to repay voter-approved 
bonded indebtedness.
 The effect of these various constitutional and 
statutory changes upon the ability of California 
municipal securities issuers to pay interest and 
principal on their obligations remains unclear. 
Furthermore, other measures affecting the taxing 
or spending authority of California or its 
political subdivisions may be approved or 
enacted in the future. Legislation has been or 
may be introduced which would modify existing 
taxes or other revenue-raising measures or which 
either would further limit or, alternatively, 
would increase the abilities of state and local 
governments to impose new taxes or increase 
existing taxes.  It is not possible, at present, 
to predict the extent to which any such 
legislation will be enacted.  Nor is it 
possible, at present, to determine the impact of 
any such legislation on California Municipal 
Obligations in which the fund may invest, future 
allocations of state revenues to local 
governments or the abilities of state or local 
governments to pay the interest on, or repay the 
principal of, such California Municipal 
Obligations.
 Substantially all of California is within an 
active geologic region subject to major seismic 
activity.  Northern California in 1989 and 
Southern California in 1994 experienced major 
earthquakes causing billions of dollars in 
damages.  The federal government provided more 
than $13 billion in aid for both earthquakes, 
and neither event is expected to have any long-
term negative economic impact. Any California 
Municipal Obligation in the Trust could be 
affected by an interruption of revenues because 
of damaged facilities, or, consequently, income 
tax deductions for casualty losses or property 
tax assessment reductions.  Compensatory 
financial assistance could be constrained by the 
inability of (i) an issuer to have obtained 
earthquake insurance coverage rates; (ii) an 
insurer to perform on its contracts of insurance 
in the event of widespread losses; or (iii) the 
federal or State government to appropriate 
sufficient funds within their respective budget 
limitations.

Tax Status of the Trust - California
In the opinion of Orrick, Herrington & 
Sutcliffe, special California counsel on 
California tax matters, under existing law 
applicable to individuals who are California 
residents: 
1. The California Trust is not an association 
taxable as a corporation for California income 
tax purposes. Under the income tax laws of 
California, income of the California Trust will 
be treated as income of Certificateholders. 
2. Interest on the underlying Securities that 
is exempt from California personal income tax 
and property tax when received by the California 
Trust will retain its status as tax-exempt 
interest when distributed to Certificateholders. 
However, interest on the underlying Securities 
attributed to a Certificateholder that is a 
corporation subject to the California franchise 
tax laws may be includable in its gross income 
for purposes of determining its California 
franchise tax. 
3. Under the income tax laws of California, 
Certificateholders in the California Trust will 
have a taxable event when the California Trust 
disposes of a Security (whether by sale, 
exchange, redemption, or payment at maturity), 
or when the Certificateholders redeem or sells 
Units. Because of the requirement that tax cost 
basis be reduced to reflect amortization of bond 
premium, under some circumstances a 
Certificateholder may realize taxable gain when 
Units are sold or redeemed for an amount equal 
to or less than their original cost. The total 
cost of each Unit to a Certificateholder is 
allocated among each of the bond issues held in 
the California Trust, in accordance with the 
proportion of the California Trust comprised by 
each bond issue, to determine its per Unit tax 
cost for each bond issue. The tax cost reduction 
requirements relating to amortization of bond 
premium will apply separately to the per Unit 
cost of each bond issue. Certificateholders may 
be required to adjust the bases of their Units 
and the bases of their fractional interests in 
each California Trust asset to reflect their pro 
rata shares of accrued interest, if any, 
received on Securities delivered after the 
Certificateholders' respective settlement dates. 
4. Bonds, including Securities, or any 
interests therein, are exempt from California 
personal property tax. 

Tax Status of the Trust
 At the time of issuance of the Securities, 
opinions regarding the validity of such 
Securities and the exemption from federal income 
tax of interest on such Securities were rendered 
by bond counsel to the respective issuers.  
Neither the Sponsor, the Trustee, nor counsel to 
either has made any review of the proceedings 
relating to the issuance of the Securities or 
the basis for such opinions.  In the case of 
certain Securities in the Trust, the opinions of 
bond counsel indicate that interest on such 
obligations received by a "substantial user" of 
the facilities being financed with the proceeds 
of such obligations, or "related person," for 
periods such obligations are held by such 
"substantial user" or "related person," will not 
be exempt from federal income tax.  Interest 
income attributable to such Securities received 
by a Unitholder who is a "substantial user" or 
"related person" may be taxable to such 
Unitholder.
 In the opinion of Carter, Ledyard & Milburn, 
counsel to the Sponsor, under existing law:
 (i) The Trust is not an association taxable as 
a corporation for U.S. federal income tax 
purposes but will be governed by the provisions 
of Subchapter J (relating to Trusts) of Chapter 
1, Internal Revenue Code of 1986 (the "Code").  
Each Unitholder will be considered as owning a 
pro rata 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 outstanding Units of such Trust.  
Under Subpart E, Subchapter J of Chapter I of 
the Code, income of the Trust will be treated as 
income of each Unitholder of the Trust in the 
proportion described.  Accordingly, to the 
extent that the income of the 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 Unitholder, except in the 
case of a Unitholder 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.  All taxpayers are 
nevertheless required to disclose to the 
Internal Revenue Service the amount of tax-
exempt interest earned during the year.  In the 
case of certain corporations, interest on all of 
the Securities is included in computing the 
alternative minimum taxable income pursuant to 
Section 56(c) of the Code.
 (ii)  If the Trustee disposes of a Security 
(whether by sale, payment at maturity, 
redemption or otherwise), gain or loss is 
recognized to the Unitholder.  A Unitholder will 
also be considered to have disposed of all or a 
portion of his pro rata portion of each Security 
when he sells or redeems some or all of his 
Units.  Such gain or loss is measured by 
comparing the Unitholder's share of such 
proceeds (or, in the case of a sale or 
redemption of Units, the portion of the proceeds 
allocable to a Security) with the Unitholder's 
adjusted basis for such Security. 
 (iii) Under the income tax laws of the State 
and City of New York, the Trust is not an 
association taxable as a corporation and income 
received by the Trust will be treated as the 
income of the Unitholders in the same manner as 
for federal income tax purposes, but will not be 
tax-exempt except to the extent that such income 
is earned on bonds in the Trust that are 
otherwise tax-exempt for New York purposes.

Additional Tax Considerations
 1.  Tax basis.  A Unitholder's initial basis in 
his Units will be equal to the cost of his 
Units, including any up-front or deferred sales 
charge and the organizational expenses borne by 
the Unitholder.  Such basis must be apportioned 
among each of the Securities and other assets of  
the Trust, as of the date the Units were 
acquired, ratably according to their values as 
of such date (or the nearest valuation date). A 
Unitholder's tax basis for his Units and for his 
fractional interest in each Trust asset must be 
reduced by the amount of his aliquot share of 
accrued interest received by the Trust, if any, 
after the date of purchase of his Units, to the 
extent that such accrued interest was included 
in the cost of his Units; must also be reduced 
by the annual amortization of bond premium, if 
any, on Securities held by the Trust; and is 
increased by the Unitholder's share of accrued 
original issue discount (and market discount, if 
the Unitholder elects to include market discount 
in income as it accrues) with respect to each 
Security held by the Trust which, at the time 
the Security was issued, had original issue 
discount (or which was purchased with market 
discount).
 2.  Bond premium.  If a Security is purchased 
for a premium over its redemption price, the 
amount of the premium is included in the tax 
basis of the Security.  Such premium is 
amortized over the remaining term of the 
Security, and the tax basis of the Security is 
reduced each tax year by the amount of the 
premium amortized in that tax year.  As a 
result, under certain circumstances Unitholders 
may realize a taxable gain upon disposition of 
Units even though such Units are sold or 
redeemed for an amount equal to or less than 
their original cost.
 3.  Original issue discount.  In the case of 
any Security held by the Trust where the "stated 
redemption price at maturity" exceeds the "issue 
price," such excess (subject to a de minimis 
rule) constitutes original issue discount.  In 
the case of any Security 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.  With respect to any 
purchaser of Securities subsequent to their 
original issuance, Section 1272(a)(7) of the 
Code provides for a reduction, under certain 
circumstances, in the accrued "daily portion" of 
such original issue discount. 
 4.  Market discount.  The Code 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 the Trust pays for 
Securities or the price a Unitholder pays for 
his Units.  Under the Code, 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 the Trust holds a Security would be 
recognized as ordinary income by the Unitholders 
when principal payments are received on the 
Security, upon sale or at redemption (including 
early redemption), or upon the sale or 
redemption of his or her Units, unless a 
Unitholder elects to include market discount in 
taxable income as it accrues.
 5.  Corporate alternative minimum tax.  Because 
the Trust does not include any "specified 
private activity bonds" within the meaning of 
Section 57(a)(5) of the Code issued on or after 
August 8, 1986, none of the Trust's interest 
income shall be treated as an item of tax 
preference when computing the alternative 
minimum tax.  In the case of corporations, the 
alternative minimum tax depends upon the 
corporation's alternative minimum taxable income 
("AMTI"), which is the corporation's taxable 
income with certain adjustments.
 Pursuant to Sections 56(c) and (g) of the Code, 
one of the adjustment items used in computing 
AMTI of a corporation (other than an S 
Corporation, Regulated Investment Company, Real 
Estate Investment Trust or REMIC) is an amount 
equal to 75% of the excess of such corporation's 
"adjusted current earnings" over an amount equal 
to its AMTI (before such adjustment item and the 
alternative tax net operating loss deduction).  
"Adjusted current earnings" includes all tax-
exempt interest, including interest on all 
Securities in the Trust, and tax-exempt original 
issue discount.
 Effective for taxable years beginning after 
December 31, 1997, the alternative minimum tax 
will not apply to corporations having annual 
gross receipts, generally, not in excess of $5 
million.
 6.  Disallowance of related items.  Under 
Section 265 of the Code, interest on 
indebtedness incurred or continued to purchase 
or carry Units 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. Also, under 
Section 265, a Unitholder will generally not be 
entitled to a deduction for his pro rata share 
of fees and expenses of the Trust, or for the 
amortization of bond premium, because they are 
incurred in connection with the production of 
tax-exempt income.  
 7.  Taxability of Social Security benefits.  
Code Section 86 provides that a portion of 
social security benefits are includible in 
taxable income for taxpayers whose "modified 
adjusted gross income", combined with 50% of 
their social security benefits, exceeds a base 
amount.  The base amount is $25,000 for an 
individual, $32,000 for a married couple filing 
a joint return, and zero for married persons 
filing separate returns.  Under Code Section 86, 
interest on tax-exempt bonds is to be added to 
adjusted gross income for purposes of 
determining whether an individual's income 
exceeds the base amount.
 The foregoing discussion relates only to U.S. 
federal and certain aspects of New York State 
and City income taxes.  Depending on their state 
of residence, Unitholders may be subject to 
state and local taxation and should consult 
their own tax advisers in this regard.  The 
preceding discussion also omits certain rules 
applicable to certain financial institutions, 
insurance companies, foreign corporations, S 
corporations and other entities subject to 
special rules under the Internal Revenue Code.

THE UNITHOLDERS, SPONSOR AND CO-TRUSTEES
THE MUNICIPAL BOND TRUST, SERIES 224 AND
THE MUNICIPAL BOND TRUST, CALIFORNIA INSURED, 
SERIES 7A:
 We have audited the accompanying statements of 
financial condition, including the schedules of 
investments, of The Municipal Bond Trust, Series 
224 and The Municipal Bond Trust, California 
Insured, Series 7A as of December 31, 1997 and 
the related statements of operations and changes 
in net assets for each of the three years in the 
period then ended. These financial statements 
are the responsibility of the Co-Trustees. Our 
responsibility is to express an opinion on these 
financial statements based on our audits.

 We conducted our audits in accordance with 
generally accepted auditing standards. Those 
standards require that we plan and perform the 
audit to obtain reasonable assurance about 
whether the financial statements are free of 
material misstatement. An audit includes 
examining, on a test basis, evidence supporting 
the amounts and disclosures in the financial 
statements. Our procedures included confirmation 
of the securities owned as of December 31, 1997, 
as shown in the statements of financial 
condition and schedules of investments, by 
correspondence with the Co-Trustees. An audit 
also includes assessing the accounting 
principles used and significant estimates made 
by the Co-Trustees, as well as evaluating the 
overall financial statement presentation. We 
believe that our audits provide a reasonable 
basis for our opinion.    

 In our opinion, the financial statements 
referred to above present fairly, in all 
material respects, the financial position of The 
Municipal Bond Trust, Series 224 and The 
Municipal Bond Trust, California Insured, Series 
7A at December 31, 1997 and the results of its 
operations and changes in its net assets for 
each of the three years in the period then 
ended, in conformity with generally accepted 
accounting principles.

              MUNICIPAL BOND TRUST
               PROSPECTUS PART B 
PART B OF THIS PROSPECTUS MAY NOT BE DISTRIBUTED
           UNLESS ACCOMPANIED BY PART A.
               NATURE OF THE TRUST
 Each series of The Municipal Bond Trust is a 
separate but similar unit investment trust, 
formed for the purpose of obtaining federally 
tax-exempt interest income consistent with the 
preservation of capital and diversification of 
risk through investment in a fixed portfolio 
comprised of "investment grade" (as of the 
Initial Date of Deposit ) interest-bearing 
Bonds. State Trusts were formed for the 
additional purpose of obtaining interest income 
exempt from state income taxes for purchasers 
who qualify as residents of the state for which 
each such Trust is named. The Sponsor and the 
Trustee do not have control over the course of 
payment of the principal of and interest on the 
Securities, therefore they cannot guarantee that 
the objectives of the Trust will be achieved. 
The interest on the Bonds, in the opinion of 
counsel to the issuers of such Bonds, is, or 
upon their issuance and delivery will be, exempt 
from present Federal income taxes. Capital 
gains, if any, will be subject to taxation.
 The portfolio of the Trust consists of 
interest-bearing Securities, issued by or on 
behalf of states, counties and municipalities 
within the United States, and authorities, 
agencies and other such political subdivisions.

              CREATION OF THE TRUST
 The Trust was created under the laws of the 
State of New York pursuant to a Trust Indenture 
and Agreement* (the "Indenture"), dated as of 
the Initial Date of Deposit, among PaineWebber 
Incorporated, as Sponsor, the Trustee identified 
in Part A of this prospectus and Kenny 
Information Systems, Inc., a division of J.J. 
Kenny Co., Inc. as Evaluator.
 On the Initial Date of Deposit, the Sponsor 
deposited with the Trustee the Securities or 
confirmations of contracts for the purchase of 
the Securities at prices determined by the 
Evaluator on the basis of current offering 
prices of the Securities. Confirmations of 
contracts for the purchase of the Bonds were 
delivered to the Trustee together with an 
irrevocable letter of credit drawn on a 
commercial bank in an amount sufficient for 
their purchase. Following the deposit, the 
Trustee delivered to the Sponsor registered 
Certificates for Units evidencing the entire 
ownership of the Trust. Each Unit represents a 
fractional undivided interest in the Trust in an 
amount equal to one divided by the total number 
of Units outstanding. On the Initial Date of 
Deposit there was one Unit for each $1,000 face 
amount of Securities deposited in the Trust.

              SUMMARY OF PORTFOLIO
 An investment in Units of the Trust should be 
made with an understanding of the risks which an 
investment in fixed rate long-term debt 
obligations may entail, including the risk that 
the value of the Trust portfolio and hence of 
the Units will decline with increases in 
interest rates. The recent period of high 
inflation, together with the fiscal measures 
adopted to attempt to deal with it, has seen 
wide fluctuations in interest rates and thus in 
the value of fixed rate long-term debt 
obligations generally. The Sponsor cannot 
predict whether such fluctuations will continue 
in the future.
 As set forth under "Essential Information" and 
"Schedule of Investments" in Part A, the Trust 
may contain or be concentrated in one or more of 
the categories of Securities referred to below. 
The types of issuers and percentages of any 
concentrations for this Trust are set forth in 
Part A. These categories are described in Part B 
because an investment in Units of the Trust 
should be made with an understanding of the 
risks which these investments may entail. Part B 
also contains a description of the features of 
this Trust.

General Obligation Bonds
 General obligation debt of an issuer that is a 
political subdivision or instrumentality of a 
state is typically secured by the full faith and 
credit of the issuer, encompassing its ability 
to levy an unlimited ad valorem tax on real 
property or other revenue streams, such as sales 
or income taxes. The fiscal condition of an 
issuer may be affected by socioeconomic factors 
beyond the issuer's control (such as relocation 
by a major employer) or other unanticipated 
events, including: natural disasters, declines 
in the state's industrial base or an inability 
to attract new industries, imposition of tax 
rate decreases or appropriations limitations by 
legislation or initiative; increased 
expenditures mandated by Federal or state law or 
by judicial decree; reduction of unrestricted 
federal or state aid and of revenue-sharing 
programs due to subsequent legislative changes 
in appropriations or aid formulas; or 
disallowances by the Federal or state 
governments for categorical grants. The fiscal 
condition of an issuer that is a political 
subdivision or instrumentality of a state (such 
as a county, city, school district or other 
entity providing public services) is related to 
the size and diversification of its tax and 
revenue base and to such other factors as: the 
effect of inflation on the general operating 
budget and of other costs, including salaries 
and fringe benefits, energy and solid waste 
disposal; changes in state law and statutory 
interpretations affecting traditional home rule 
powers (which vary from state to state); levels 
of unrestricted state aid or revenue-sharing 
programs and state categorical grants subject to 
annual appropriation by a state legislature; 
increased expenditures mandated by state law or 
judicial decree; and disallowances for expenses

Indenture and Agreement and any statements

by the provisions of said Trust Indenture and 
Agreement.
incurred under Federal or state categorical 
grant programs. The local economy may be or 
become concentrated (i) in a single industry, 
which may be affected by natural or other 
disasters or by fluctuations in commodity 
prices, or (ii) in a particular company, the 
operations of which may be impaired due to labor 
disputes, relocation, bankruptcy or corporate 
take-over. Such economic factors may, in turn, 
affect local tax collections and service 
demands. The ability of an issuer to levy 
additional taxes may be subject to state 
constitutional provisions, assent of the state 
legislature or voter approval in a local 
referendum, or constrained by economic or 
political considerations. Recent changes in 
Federal welfare policy may have substantial 
negative impact on certain states and localities 
within such states, which may in turn make their 
ability to maintain balanced budgets more 
difficult in future years.

Revenue Bonds
 Revenue Bonds are securities issued by states, 
municipalities, public authorities and other 
similar entities to finance the cost of 
constructing, acquiring or improving various 
projects. Unlike general obligation bonds, 
municipal revenue bonds are not backed by their 
issuer's taxing power or full faith and credit 
and payment on municipal revenue bonds is 
generally dependent solely upon revenues 
generated by the project or in some cases, 
specific state appropriations or excise taxes. 
Examples of municipal revenue bonds are: housing 
facility securities, airport facilities, power 
and electronic facilities, and others listed 
below in bold typeface. A brief discussion of 
some of the risks associated with such revenue 
bonds follows.

Housing Facility Securities
 These Securities are typically secured by 
mortgage revenues derived by state housing 
finance agencies, municipal housing authorities 
or certain non-profit organizations from 
repayments on mortgage and home improvement 
loans made by such entities. Special 
considerations affecting housing securities 
include: the condition of the local housing 
market, competition from conventional mortgage 
lenders, fluctuations in interest rates, 
increasing construction costs and the ability of 
the Issuers, lenders, servicers and borrowers to 
maintain program compliance under applicable 
statutory provisions. Federal tax legislation 
adopted during the 1980s imposed progressively 
more restrictive requirements for post-issuance 
compliance necessary to maintain the tax 
exemption on both single family and multi-family 
housing securities. To maintain the security's 
tax exemption, the issuer may be required 
pursuant to the legal documents governing the 
Security to redeem all or a portion of such 
obligations at par; the Sponsor is unable to 
predict whether such redemptions will occur, or 
what effect, if any, such redemptions would have 
on any such Securities in the Trust. 
 Additional considerations with regard to 
single-family housing securities include: the 
underwriting and management ability of the 
issuers, lenders and servicers (i.e., the 
initial soundness of the loan and the effective 
use of available remedies should there be a 
default in loan payments); the financial 
condition and credit rating of the private 
mortgage insurer underwriting the insurance on 
the underlying mortgage or pool of mortgages; 
and special risks attendant to lending to 
mortgagors, most of whom are first time home 
buyers of low or moderate means. During periods 
of declining interest rates, there may be 
increased redemptions of single family housing 
securities from unexpended proceeds due to 
insufficient demand, because conventional 
mortgage loans may become available at interest 
rates equal to or less than the interest rates 
charged on the mortgage loans made available 
from bond proceeds. In addition, certain 
mortgage loans may be prepaid earlier than their 
maturity dates, because mortgage loans made with 
bond proceeds usually do not carry prepayment 
penalties. Additional considerations with regard 
to multi-family housing securities include: 
increasing operating costs; the ability or 
failure to increase rental charges; and the 
financial condition of housing authority Issuers 
and their ability to meet certain requirements 
under the Section 8 program of the United States 
Housing Act of 1937, as amended. Multi-family 
housing securities may also be subject to full 
or partial redemption at par from the proceeds 
of the sale, assignment or disposition of a 
defaulted mortgage loan or acceleration of 
principal payments thereunder; a condemnation or 
insurance award; or a result of the reduction of 
a required reserve fund.

Airport Facilities
 Bonds in the airport facilities category are 
payable from and secured by revenues derived 
from the gross airport operating income. The 
major portion of gross airport operating income 
is generally derived from fees received from 
signatory airlines pursuant to use agreements 
which consist of annual payments for airport 
use, occupancy of certain terminal space, 
facilities, service fees, concessions and 
leases. Airport operating income may be affected 
by local economic conditions, air traffic 
patterns, noise abatement restrictions or 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 
deregulation, recent consolidations through 
mergers and acquisitions, increased competition, 
excess industry capacity, fluctuations in fuel 
and other costs, traffic constraints and other 
factors. In particular, facilities with use 
agreements involving airlines experiencing 
financial difficulty may experience a reduction 
in revenue due to the possible inability of 
these airlines to meet their use agreement 
obligations. The Sponsor is now unable to 
predict what effect, if any, air transport 
industry conditions will have on the airport 
Bonds in the Trust.

Hospital and Health Care Facility Securities 
 Bonds in the hospital and health care 
facilities category are payable from revenues 
derived from hospital, mental health, nursing 
home and other health care facilities which, 
generally, were constructed or are being 
constructed with bond proceeds. Payment of such 
bonds derives generally from revenues of health 
care providers. The continuing availability of 
sufficient revenues is dependent upon several 
factors affecting all such facilities generally, 
including, among other factors: utilization 
rates; the cost and availability of malpractice 
insurance and the outcome of malpractice 
litigation; curtailment of operations due to 
shortages in qualified medical staff or labor 
disputes; changes in Federal, state and private 
reimbursement regulations and health care 
delivery programs. The extent of the AIDS 
epidemic is undetermined, and the Sponsor cannot 
predict its full impact on the health care 
system or particular issuers. Utilization rates 
for a particular facility may be determined by 
cost containment programs implemented by third 
party governmental providers or private 
insurers; long-term advances in health care 
delivery reducing demand for in-patient 
services; technological developments which may 
be effectively rationed by the scarcity of 
equipment or specialists; governmental approval 
and the ability to finance equipment 
acquisitions; increased competition due to 
elimination of certain certificate of need 
requirements in some states; and physicians' and 
public perceptions as to standards of care. 
Requirements for Federal or state licenses, 
certifications and contract eligibility and for 
accreditation are subject to change, and may 
require participating facilities to effect 
costly modifications in operations. Medicare 
payments have been, and may continue to be, 
reduced under legislation adopting deficit 
reduction measures. Additionally, certain states 
have recently implemented prospective payment 
systems for their Medicaid programs, and have 
adopted other changes, including enrollment 
restrictions. The Sponsor cannot predict the 
effect, if any, of further reductions in 
Medicare and Medicaid payments on the revenues 
of Issuers of health care Securities in the 
Trust. Many hospitals, including certain issuers 
(or the conduit obligors) of Securities in the 
Trust, have been experiencing significant 
financial difficulties in recent years. 
Generally, a number of additional legislative 
proposals concerning health care may be 
introduced in Congress at any time. Recently, 
these proposals have covered a wide range of 
topics, including cost controls, national health 
insurance, incentives for competition in the 
provision of health care services, tax 
incentives and penalties related to health care 
insurance premiums, and promotion of prepaid 
health care plans. The Sponsor is unable to 
predict the effect of any of these proposals, if 
enacted, on any of the Bonds in the Trust 
portfolio. The Internal Revenue Service (the 
"IRS") has been engaged in a program of 
extensive audits of certain large tax-exempt 
hospitals and health care providers. Although 
such audits have not yet been completed there 
have been reports that the tax-exempt status of 
certain of these organizations may be revoked 
and/or that certain monetary penalties may be 
owed to the IRS.

Power and Electric Facility Securities 
 These Securities are typically secured by 
revenues derived from power generating 
facilities, which generally include revenues 
from the sale of electricity generated and 
distributed by power agencies using 
hydroelectric, nuclear, fossil fuel or other 
power sources. Certain aspects of the operation 
of such facilities, particularly with regard to 
generation and transmission at the wholesale 
level, are subject to federal regulation and 
more extensive regulation (affecting retail rate 
structures) is provided by state public service 
commissions. Special considerations include: 
restrictions on operations and increased costs 
and delays attributable to environmental statues 
and regulations; the difficulties of the 
utilities in financing or refinancing large 
construction programs and of the capital markets 
in absorbing utility debt and equity securities; 
fluctuations in fuel supplies and costs, and 
costs associated with conversion to alternate 
fuel sources; uncertainties with regard to 
demand projections due to changing economic 
conditions, implementation of energy 
conservation measures and competitive 
cogeneration projects; and other technical and 
cost factors. Recent scientific breakthroughs in 
fusion energy and superconductive materials may 
cause current technologies for the generation 
and transmission of electricity to become 
obsolete during the life of the Securities in 
the Portfolio. Issuers relying upon 
hydroelectric generation may encounter contests 
when applying for periodic renewal of licenses 
to operate dams. Issuers relying upon coal as a 
fuel source may be subject to significant costs 
and operating restrictions to comply with 
emission standards which may be adopted to 
alleviate the problems associated with acid 
rain. Issuers relying upon fossil fuel sources 
and located in air quality regions designated as 
nonattainment areas may become subject to 
pollution control measures (which could include 
abandonment of construction projects in 
progress, plant shutdowns or relocation of 
facilities). In addition, such Securities are 
sometimes secured by payments to be made to 
state and local joint action power agencies 
pursuant to "take or pay" agreements. Such 
agreements have been held unenforceable by state 
courts in Idaho, Vermont and Washington, which 
may cause an examination of the legal structure 
of certain projects in other states and could 
possibly lead to litigation challenging the 
enforceability of such agreements. 
 Some of the issuers of Securities in the Trust 
may own, operate or participate on a contractual 
basis with nuclear generating facilities, which 
may experience additional problems including: 
the frequency and duration of plant shutdowns 
and associated costs due to maintenance or 
safety considerations; the problems and 
associated costs related to the use and disposal 
of radioactive materials and wastes in 
compliance with Federal and local law; the 
implementation of emergency evacuation plans for 
areas surrounding nuclear facilities; and other 
issues associated with construction, licensing, 
regulation, operation and eventual 
decommissioning of such facilities. These 
Securities may be subject to industry-wide 
fluctuations in market value as a consequence of 
market perception of certain highly publicized 
events, as in the Washington Public Power Supply 
System's defaults on its Project 4 and 5 revenue 
bonds and the 1988 bankruptcy filing by the 
Public Service Corporation of New Hampshire. 
Federal, state or municipal governmental 
authorities, or voters by initiative, may from 
time to time impose additional regulations or 
take such other governmental action which might 
cause delays in the licensing, construction or 
operation of nuclear power plants, or the 
suspension or cessation of operations of 
facilities which have been or are being financed 
by proceeds of certain Securities in the Trust. 
Additionally, the recent movement to introduce 
competition in the investor-owned electric 
utility industry is likely to affect, at least 
indirectly, municipal utility systems by driving 
them to maintain low rates. In an effort to keep 
their rates low, municipal utilities may 
experience difficulties in raising rates to 
completely recover their investment in 
generating plants.

Industrial Development/Pollution Control 
Securities 
 These Securities were generally issued prior to 
the enactment of 1986 Code restrictions, and are 
typically secured by payments made under a loan 
agreement entered into between the issuer and 
the obligor. In some cases, the Securities were 
additionally secured by guarantees provided by 
corporate guarantors or by a stand-by letter of 
credit issued by a bank. Special considerations 
include: the financial condition of the 
corporate obligor (or guarantor), especially as 
it may be affected by subsequent corporate 
restructuring or changes in corporate control.

Public Facilities Securities 
 These Securities are typically secured by 
revenues derived from either (i) payments 
appropriated by governmental entities for the 
use of equipment or facilities, such as 
administrative or correctional buildings, or 
(ii) user charges or other revenues derived from 
such operations as parking facilities, 
convention centers or sports arenas. In the 
first instance, the pledged revenues may be 
subject to annual appropriation by legislative 
body. In the latter case, the collection of 
revenues may be dependent upon the reliability 
of feasibility forecasts and assumptions 
concerning utilization rates. 

Resource Recovery/Solid Waste Securities 
 These Securities are typically secured by 
revenues derived from the sale of electricity or 
steam generated as a by-product of the process 
of incinerating solid waste, and from 
contractual tipping fees, user charges and 
ancillary recycling earnings. Special 
considerations include: the supply of solid 
waste at levels sufficient for the facility to 
operate at design capacity; the frequency and 
duration of plant shutdowns for maintenance; the 
treatment and disposal of fly ash which contains 
toxic substances, especially dioxin; compliance 
with air pollution control standards; 
unanticipated problems associated with the use 
of developing technologies; and the continuation 
of federal policies facilitating congeneration 
and certification of any particular qualifying 
facility. Governmental service contract payments 
may be subject to annual appropriation by a 
legislative body. Older facilities may require 
retrofitting to accommodate new technological 
developments or to comply with environmental 
standards. A recent decision of the United 
States Supreme Court limiting a municipality's 
ability to require the use of its facilities may 
have an adverse affect on the credit quality of 
certain securities.

Water and Sewer Facility Securities 
 Bonds described as "water and sewer" facilities 
Bonds are typically secured by a pledge of the 
net revenues derived from connection fees and 
user charges imposed by the enterprise. Such 
Bonds are subject to the risks typically 
associated with construction projects. Among the 
factors which may affect net revenues are the 
destruction of facilities due to natural or 
other disasters; relocation out of the service 
area by a major customer or customers due to 
economic factors beyond the issuer's control; or 
costs incurred due to prior periods of deferred 
maintenance or compliance with Federal or state 
environmental standards. Water system revenues 
may be additionally affected by the terms of 
supply allocations and service agreements with 
major wholesale customers and the imposition of 
mandatory conservation measures in response to 
drought. Sewer system revenues may be 
additionally affected by costs to comply with 
effluent and other standards pursuant to the 
Federal and state laws.

Student Loan Securities 
 Student loan revenue securities are issued 
either by non profit corporations organized for 
the purpose of acquiring student loans 
originated under the Higher Education Act ("the 
Act") or public agencies or instrumentalities of 
a state created to provide loans for educational 
purposes. Proceeds of securities issued by such 
entities generally are used to make or acquire 
student loans which are either (1) guaranteed by 
guaranty agencies and reinsured by the U.S. 
Secretary of Education, (2) are insured directly 
by the federal government or (3) not guaranteed 
at all (e.g. alternative or supplemental student 
loans). Bonds issued by such entities are 
generally secured by and dependent upon such 
state guarantee programs, Federal insurance and 
reimbursement programs, the proceeds from 
payment of principal and interest on the 
underlying student loans and federal interest 
subsidy and/or special allowance payments. 
Failure by the servicers of student loans on the 
guaranty agencies guaranteeing such loans to 
properly service and enforce the loans may cause 
the reimbursements to decline or be withheld 
under the Act, if applicable.
 Both the Act and the regulations promulgated 
thereunder have been the subject of extensive 
amendments in recent years, and the Sponsor can 
give no assurance that further amendment will 
not materially change the provisions or the 
effect thereof.
 The availability of various Federal payments in 
connection with the Federal student loan program 
is subject to Federal budgetary appropriation. 
In recent years, legislation has been enacted 
which has provided, for the recovery of certain 
advances previously made by the Federal 
government to state guaranty agencies in order 
to achieve deficit reduction. No representation 
is made as to the effect, if any, or future 
Congressional appropriation or legislation upon 
expenditures by the Department of Education or 
upon the financial condition of any guaranty 
agency.

Lease Payment Bonds
 Lease Payment bonds are generally issued by 
governmental financing authorities with no 
direct taxing power for the construction of 
buildings or the purchase of equipment to be 
used by a state or local government. Such bonds 
may be principally secured by governmental lease 
payments which in turn are subject to the budget 
appropriations of the participating governmental 
entity. A governmental entity that enters into a 
lease agreement cannot obligate future 
governments to make lease payments but generally 
will covenant to take such action as is 
necessary to include all lease payments due 
under an agreement in its annual budgets and to 
make the appropriations therefor. The failure of 
a governmental entity to meet its obligations 
under a lease could result in an insufficient 
amount of funds to cover payment of the Bonds 
secured by such lease payments. Such bonds may 
also be subject to the risk that rental 
obligations may terminate in the event of 
destruction or damage of the equipment or 
buildings.

Tax Allocation Bonds 
 Bonds described as "tax allocation" securities 
are payable from and secured by incremental 
(increased) tax revenues collected on property 
within the areas where redevelopment projects, 
financed by bond proceeds, are located ("project 
areas"). Payments on these bonds are expected to 
be made from projected increases in tax revenues 
derived from higher assessed value of property 
resulting from development in the particular 
project area and not from an increase in the tax 
rates. Among the factors which could result in a 
reduction of the allocated tax revenues which 
secure a tax allocation Bond are: (i) reduction 
of, or a less than anticipated increase in, 
taxable values of property in the project area, 
caused either by economic factors beyond the 
issuer's control (such as a relocation out of 
the project area by one or more major property 
owners) or by destruction of property due to 
natural or other disasters; (ii) successful 
appeals by property owners of assessed 
valuations; (iii) substantial delinquencies in 
the payment of property taxes; or (iv) 
imposition of any constitutional or legislative 
property tax rate decrease. Such reduction of 
tax revenues could have an adverse effect on an 
issuer's ability to make timely payments of 
principal and of interest on the Bonds. 

Refunded Bonds 
 Refunded bonds (including bonds escrowed to a 
call date or maturity date) are bonds that 
originally had been issued generally as revenue 
bonds but have been refunded for reasons which 
may include changing the issuer's debt service 
requirements and removing restrictive bond 
covenants. Typically, a refunded bond is no 
longer secured by a pledge of revenues received 
by an issuer but rather by an escrow fund 
consisting of U.S. Government Obligations. In 
such cases the issuer establishes an escrow fund 
which is irrevocable and which cannot be 
depleted by the issuer so long as debt service 
on the refunded bonds is required to be paid. 
Each escrow fund is funded with U.S. Government 
Obligations which are designed to make payments 
on the refunded bonds and which cannot be 
affected by a default of the issuer. An escrow 
agent pays principal, redemption premium, if 
any, and interest on the refunded bond from the 
principal of and interest on the U.S. Government 
Obligations in the escrow fund. The Trust, as 
holder of the refunded bonds, is entitled to 
receive such payment of principal, redemption 
premium, if any, and interest on the refunded 
bonds as it is paid by the escrow agents out of 
the respective refunded bond escrow funds. 
Investors should note that there have, however, 
been a few bonds thought to be escrowed to 
maturity that were, in fact, called for 
redemption prior to maturity.

Crossover Refunding Bonds 
 Certain Bonds in the Trust may be cross-over 
refunding Bonds. Prior to a specified date, (the 
"Crossover Date"), such bonds are payable solely 
from an escrow fund invested in specified 
securities. After the Crossover Date the Bonds 
are payable from a designated source of 
revenues. Such bonds are categorized in Part A 
as payable from such source of revenues.

Bonds Backed by Letters of Credit 
 The Trust may contain securities that are 
secured by letters of credit issued by 
commercial or savings banks which may be drawn 
upon (i) if an issuer fails to make payments of 
principal of, premium, if any, or interest on a 
Bond backed by such a letter of credit or (ii) 
in the event interest on a Bond is deemed to be 
taxable and full payment of principal and any 
premium due is not made by the issuer. The 
letters of credit are irrevocable obligations of 
the issuing banks. Banks are subject to 
extensive governmental regulations. The 
profitability of the banking industry is largely 
dependent upon the availability and cost of 
capital funds for the purpose of financing 
lending operations under prevailing money market 
conditions. Also, general economic conditions 
play an important part in the operations of the 
banking industry and exposure to credit losses 
arising from possible financial difficulties of 
borrowers or other issuers having letters of 
credit might affect a bank's ability to meet its 
obligations under a letter of credit.

Insurance on the Bonds in the Portfolio
Certain of the Bonds in the Trust may have 
been insured to maturity by the insurance 
company listed in the table below as to payment 
of principal and interest by the issuer at the 
time of issuance, or by a third party purchaser 
of Bonds subsequent to the issuance of such 
bonds. In an Insured Series, in addition to 
purchasing Bonds insured at the time of their 
issuance, the Sponsor may have purchased bonds 
which, prior to the Initial Date of Deposit, 
were not so insured at the time of issuance. The 
Sponsor has obtained an insurance policy or 
policies (except as otherwise set forth in Part 
A) for such bonds which were not originally 
insured. The policies obtained by the Sponsor 
provide either for insurance as long as the 
Bonds so insured remain outstanding ("Insurance 
to Maturity") or which continue in force only so 
long as the Bonds so insured remain in the 
Insured Trust ("Portfolio Insurance"). (See Part 
A, "Essential Information-Insurance"). Portfolio 
Insurance, if any, has been obtained from 
Financial Guaranty. Any Insured Trust which has 
obtained Portfolio Insurance has additionally 
obtained an irrevocable commitment (the 
"Irrevocable Commitment") of Financial Guaranty 
to provide insurance to maturity ("Permanent 
Insurance") upon the sale of any Bond covered by 
the Portfolio Insurance from such Trust and upon 
payment of a premium (the "Permanent Insurance 
Premium") under certain conditions set forth in 
Part A under the heading "Essential Information 
Regarding the Trust". The value of the Bonds 
covered by the Portfolio Insurance and, 
therefore, the Units may decline in the event of 
declining credit quality. However, because of 
the Irrevocable Commitment to provide Permanent 
Insurance, whenever the value of a Bond which is 
below investment grade and which is covered by 
the Portfolio Insurance and insured to its 
maturity (less the Permanent Insurance Premium) 
exceeds the value of that Bond without such 
insurance, the value of that Bond will be 
higher, insured to maturity value (See 
"Evaluation of the Trust"). The insurance 
policies are non-cancellable and will remain in 
force as long as the Bonds insured by such 
policies remain outstanding. Premiums for 
Insurance to Maturity has been paid either at 
the time of issuance by the Issuer, by third-
party purchasers or by the Sponsor on the 
Initial Date of Deposit (See "Summary of 
Portfolio-Insurance Premiums"). Premiums for 
Portfolio Insurance are an expense of an Insured 
Trust. (See "Expenses of the Trust"). Insurance 
does not guarantee the market value of the Bonds 
or the value of the Units. Although the 
insurance represents an element of market value 
with respect to the Bonds covered by Insurance 
to Maturity, the exact effect, if any, of this 
insurance on the market value cannot be 
predicted. No value is attributed to Portfolio 
Insurance unless the Bond so insured is rated 
below investment grade. See "Essential 
Information Regarding the Trust-Securities in 
the Trust Portfolio" in Part A for information 
on the insurance features of this Trust, if any, 
and a description of the percentages of the 
Bonds covered by each of the insurers.
Payment under all of these insurance policies 
will be made in respect of principal of and 
interest on Bonds which shall be due for payment 
under the provisions of each policy, but shall 
be unpaid. All such policies provide for payment 
of the principal or interest due to a trustee or 
paying agent on the date such payment is due. In 
turn, such trustee or paying agent will make 
payment to the bondholder (in this case, the 
Trustee) upon presentation of satisfactory 
evidence of such Bondholder's right to receive 
such payment. Policies issued by Industrial 
Indemnity Insurance Company prior to December 
17, 1984 permit the Company, at its option, to 
accelerate payments under the insurance 
policies. Most insurance policies, however, do 
not provide for accelerated payments of 
principal or interest nor do they cover 
redemptions resulting from events of taxability.
 The following summary information relating to 
the listed insurance companies has been obtained 
from publicly available information. Certain 
insurance companies have been restructured and 
have been absorbed or merged into others; in 
such cases the names of the original insurance 
company appear in parentheses next to the name 
of the acquiring or surviving insurance company.

Insurance companies are subject to extensive 
regulation and supervision where they do 
business by state insurance commissioners who 
regulate the standards of solvency which must be 
maintained, the nature of limitations on 
investments, reports of financial condition, and 
requirements regarding reserves for unearned 
premiums, losses and other matters. A 
significant portion of the assets of insurance 
companies are required by law to be held in 
reserve against potential claims on policies and 
is not available to general creditors. Although 
the federal government does not regulate the 
business of insurance, federal initiatives 
including pension regulation, controls on 
medical care costs, minimum standards for no-
fault automobile insurance, national health 
insurance, tax law changes affecting life 
insurance companies and repeal of the antitrust 
exemption for the insurance business can 
significantly impact the insurance business.

Ratings on the Bonds in the Insured Series and 
on Units of the Insured Series
 On the Initial Date of Deposit Standard & 
Poor's Corporation rated each of the Bonds in 
the Portfolio and the Units of each Insured 
Trust "AAA" because the insurers have issued 
insurance policies to insure each of the Bonds. 
The Units of each Insured Trust (with the 
exception of Units of those Insured Trusts 
identified in Part A) continue to be rated 
"AAA". See Part A for the current ratings on the 
Bonds and Units. (See also "Bond Ratings", 
herein). The Bond and Unit ratings should not be 
construed as an approval of the offering of the 
Units by Standard & Poor's Corporation or as a 
guarantee of the market value of the Trust or of 
the Units. Standard & Poor's has been 
compensated by the Sponsor for its services in 
rating Units of the Trust.

Insurance Premiums
 The cost of the Insurance to Maturity has been 
paid either by the issuers at the time of 
issuance, by third-party purchasers or by the 
Sponsor. Portfolio Insurance premiums are a 
Trust expense.

Risk Factors Pertaining to a Single State Trust
 Investment in a Trust which holds securities 
issued only by obligors in a single state, such 
as California, may involve additional risks to 
that of an investment in a Trust with a 
portfolio of securities from several states, due 
to the decreased diversification of political, 
financial, economic and market risks. A brief 
description of the factors which may affect the 
financial condition of the applicable state, 
together with a discussion of certain tax 
considerations relating to such state, appear in 
Part A.

Legislation
 From time to time, proposals are introduced in 
Congress to, among other things, reduce federal 
income tax rates, impose a flat tax, exempt 
investment income from tax or abolish the 
federal income tax and replace it with another 
form of tax. Enactment of any such legislation 
could adversely affect the value of the Units. 
The Sponsor, however, cannot predict what 
legislation, if any, in respect of tax rates may 
be proposed, nor can it predict which proposals, 
if any, might be enacted. Also, certain 
proposals, in the form of state legislative 
proposals or voter initiatives, seeking to limit 
real property taxes have been introduced in 
various states, and an amendment to the 
Constitution of the State of California, 
providing for strict limitations on real 
property taxes, has had a significant impact on 
the taxing powers of local governments and on 
the financial condition of school districts and 
local governments in California. In addition, 
other factors may arise from time to time which 
potentially may impair the ability of issuers to 
make payments due on the Bonds. Under the 
Federal Bankruptcy Code, for example, municipal 
bond issuers, as well as any underlying 
corporate obligors or guarantors, may proceed to 
restructure or otherwise alter the terms of 
their obligations.

 From time to time, Congress considers proposals 
to prospectively and retroactively tax the 
interest on state and local obligations, such as 
the Bonds. The Supreme Court clarified in South 
Carolina v. Baker (decided on April 20, 1988) 
that the U.S. Constitution does not prohibit 
Congress from passing a nondiscriminatory tax on 
interest on state and local obligations. This 
type of legislation, if enacted into law, could 
require investors to pay income tax on interest 
from the Bonds and could adversely affect an 
investment in Units.

Payment of the Bonds and Life of the Trust
 The size and composition of the Portfolio will 
change over time. Most of the Bonds are subject 
to redemption prior to their stated maturity 
dates pursuant to optional refunding or sinking 
fund redemption provisions or otherwise. In 
general, optional refunding redemption 
provisions are more likely to be exercised when 
the value of a Bond is at a premium over par 
than when it is at a discount from par. Some 
Bonds may be subject to sinking fund and 
extraordinary redemption provisions which may 
commence early in the life of the Trust. 
Additionally, the size and composition of the 
Trust will be affected by the level of 
redemptions of Units that may occur from time to 
time. Principally, this will depend upon the 
number of investors seeking to sell or redeem 
their Units and whether or not the Sponsor is 
able to sell the Units acquired by it in the 
secondary market. As a result, Units offered in 
the secondary market may not represent the same 
face amount of Bonds as on the initial date of 
deposit. Factors that the Sponsor will consider 
in determining whether or not to sell Units 
acquired in the secondary market include the 
diversity of the Portfolio, the size of the 
Trust relative to its original size, the ratio 
of Trust expenses to income, the Trust's current 
and long-term returns, the degree to which Units 
may be selling at a premium over par and the 
cost of maintaining a current prospectus for the 
Trust. These factors may also lead the Sponsors 
to seek to terminate the Trust earlier than its 
mandatory termination date.

Ratings
 Each of the Bonds in the Trust was, as of the 
Initial Date of Deposit, rated "A" or higher by 
either Standard & Poor's Corporation or Moody's 
Investors Service, Inc. (see "Schedule of 
Investments") or were Bonds which the Sponsor 
reasonably believed would have obtained such 
minimum rating soon thereafter. Ratings 
indicated on the Schedule of Investments are 
Standard & Poor's Corporation ratings unless no 
rating was given to a Bond by such rating 
service or the rating category assigned by 
Moody's Investors Service, Inc. was higher, in 
which case the Moody's Investors Service, Inc. 
rating was indicated. Certain Bonds may, in 
addition to their rating, be designated either 
"p" by Standard & Poor's Corporation or "Con" by 
Moody's Investors Service, Inc. Such 
designations do not affect the rating assigned 
by the respective rating services to such Bonds 
but provide certain additional information (see 
"Bond Ratings" in Part B and "Schedule of 
Investments" in Part A).

ACQUISITION OF SECURITIES FOR THE TRUST
 In selecting Bonds for deposit in the Trust 
many factors were considered, and based upon the 
experience and judgment of the Sponsor, the 
following requirements, among others, were 
deemed to be of primary importance: 
 1. Minimum Standard & Poor's Corporation's 
rating of "A-" or minimum Moody's Investors 
Service, Inc.'s rating of "A" ("investment 
grade" municipal bonds) or Bonds which the 
Sponsor reasonably believes will obtain such 
minimum ratings in the near future;
 2. Reasonable value relative to other issues of 
similar quality and maturity;
 3. Diversification as to the purpose of each 
issue and the location of each issuer; and 
 4. Income to the Unitholders of the Trust. 
 Cash, if any, received from Unitholders prior 
to the settlement date for the purchase of Units 
or prior to the payment for Bonds upon their 
delivery may be used in the Sponsor's business 
subject to the limitations of 17 C.F.R. Section 
240. 15c3-3 under the Securities and Exchange 
Act of 1934 and may be of benefit to the 
Sponsor.
 The Trustee has not participated in the 
selection of Securities for the Trust, and 
neither the Sponsor nor the Trustee will be 
liable in any way for any default, failure or 
defect in any Securities.
 To the best knowledge of the Sponsor, there was 
no litigation pending as of the Initial Date of 
Deposit in respect of any Securities which might 
reasonably be expected to have a material 
adverse effect upon the Trust. At any time after 
the Initial Date of Deposit, litigation may have 
been initiated on a variety of grounds with 
respect to Securities in the Trust. Such 
litigation may affect the validity of such 
Securities or the tax-exempt status of the 
interest thereon. While the outcome of 
litigation of such nature cannot be predicted, 
opinions of the bond counsel are delivered with 
respect to each Security on the date of issuance 
to the effect that such Security has been 
validly issued and that the interest thereon is 
exempt from Federal income tax. If legal 
proceedings are instituted after the Initial 
Date of Deposit seeking, among other things, to 
restrain or enjoin the payment of any of the 
Bonds or attacking their validity or the 
authorization or existence of the issuer, the 
Sponsor may, in accordance with the Indenture, 
direct the Trustee to sell such Bonds and 
distribute the proceeds of such sale to 
Unitholders. 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 Bonds.

PUBLIC OFFERING PRICE OF UNITS
 The Public Offering Price per Unit during the 
secondary market will be computed by dividing 
the aggregate of the bid prices of the Bonds in 
the Trust plus any money in the Principal 
Account other than money required to redeem the 
tendered Units, by the number of Units 
outstanding, and then adding the appropriate 
sales charge. If the primary offering period, 
the Public Offering Price was determined on the 
basis of the offering prices of bonds plus a 
sales charge ranging from 3.5% to 5.5% of the 
Public Offering Price. 
 The sales charge is determined in accordance 
with the table set forth below based upon the 
number of years remaining to the maturity of 
each Bond. There is no sales charge with respect 
to cash held in the Interest or Principal 
Accounts. For purposes of this calculation, 
Bonds will be deemed to mature on their stated 
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 ("Refunded Bonds"), in which 
case such call date shall be deemed to be the 
date upon which they mature; or (b) such Bonds 
are subject to a "mandatory put", in which case 
such mandatory put date shall be deemed to be 
the date upon which they mature. 
 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:
                                 Maximum                
                                 Percent of             
Remaining                        Public       Percent of
Years to                         Offering     Net Amount
Maturity                         Price        Invested  
Less than six months             0%           0%        
Six months to less than 1 year   0.50         0.503     
1 year to less than 2 years      1.00         1.010     
2 years to less than 3 years     1.50         1.523     
3 years to less than 4 years     2.25         2.302     
4 years to less than 5 years     2.75         2.828     
5 years to less than 6 years     3.00         3.093     
6 years to less than 7 years     3.25         3.359     
7 years to less than 8 years     3.50         3.627     
8 years to less than 9 years     4.00         4.167     
9 years to less than 12 years    4.25         4.439     
12 years to less than 15 years   4.50         4.712     
15 years or more                 5.50         5.820     
 For example, the sales charge on a Trust 
consisting entirely of Bonds maturing in 12 to 
15 years would be 4.50% (4.712% of the net 
amount invested) and that on a Trust consisting 
entirely of Bonds maturing in four to five years 
would be 2.75% (2.828% of the net amount 
invested). The actual sales charge included in 
the Public Offering Price of any particular 
Trust will depend on the maturities of the Bonds 
in the portfolio of such Trust. 
 Due to the realization of economies of scale in 
sales effort and sales related expenses with 
respect to the purchase of Units by employees of 
the Sponsor, the Sponsor intends to permit 
employees of the Sponsor and certain of their 
relatives to purchase Units of the Trust at a 
price equal to the bid-side evaluation of the 
Securities in the Trust divided by the number of 
Units outstanding plus a reduced sales charge of 
$5.00 per Unit. 
 A proportionate share of accrued interest and 
undistributed interest on the Units to the 
Unitholder's settlement date (the Unitholder's 
settlement date is the date so specified in the 
confirmation of sale of the Units to a 
Unitholder, normally five business days after 
purchase) is added to the Public Offering Price. 
Such proportionate share will be an asset of the 
Unitholder and will be received in subsequent 
distributions and upon the sale of his Units.
 Aggregate bid prices of the Securities will be 
determined for the Trust by the Evaluator on the 
basis of: (1) the current bid prices for the 
Securities; (2) the current bid prices for 
comparable bonds, if bid prices are not 
available for any of the Securities; (3) 
determining the value of the Securities on the 
bid side of the market by appraisal; or (4) any 
combination of the above. Such evaluations and 
computations will be made each business day as 
of the Evaluation Time, effective for all sales 
or redemptions made subsequent to the last 
preceding determination.
 In addition to the sales charges, on the 
Initial Date of Deposit, the Sponsor realized a 
profit or loss resulting from the difference 
between the purchase price paid by the Sponsor 
to buy the Securities and the cost of the 
Securities to the Trust as determined by the 
Evaluator. The Sponsor may realize additional 
profit or loss as a result of the possible 
change in the daily evaluation of the Bonds in 
the Trust. All proceeds received from purchasers 
of Units of the Trust will be retained by the 
Sponsor.

PUBLIC OFFERING OF UNITS
 The Sponsor intends to qualify Units for sale 
in all of the states of the United States, 
except that for state trusts, the Sponsor 
intends to qualify Units for sale only to 
residents of that state. Sales may be made to 
dealers who are members of the National 
Association of Securities Dealers, Inc. at 
prices which include a concession of 75% of the 
applicable sales charge subject to change from 
time to time. The difference between the dealer 
concession and the sales charge will be retained 
by the Sponsor. The Sponsor reserves the right 
to reject, in whole or in part, any order for 
the purchase of Units. 
 Initial Offering of Units. During the initial 
public offering period, Units were offered to 
the public by the Sponsor at the Public Offering 
Price calculated on each business day, plus 
accrued interest.
 Secondary Offering of Units. Upon the 
termination of the initial public offering 
period, unsold Units or Units acquired by the 
Sponsor in the secondary market referred to 
below may be offered to the public by the 
Sponsor by this Prospectus at the then current 
Public Offering Price, calculated daily, plus 
accrued interest.

SECONDARY MARKET FOR UNITS
 While not obligated to do so, it is the 
Sponsor's present intention to maintain, at its 
expense, a secondary market for Units of this 
Series and to offer to repurchase Units from 
Unitholders at the "Sponsor's Repurchase Price". 
The Sponsor's Repurchase Price is computed by 
dividing the value of the Trust by the number of 
Units outstanding (see "Evaluation of the 
Trust"). There is no sales charge incurred when 
a Unitholder sells Units back to the Sponsor. 
Any Units repurchased by the Sponsor at the 
Sponsor's Repurchase Price may be reoffered to 
the public by the Sponsor at the then current 
Public Offering Price, plus accrued interest. 
Any profit or loss resulting from the resale of 
such Units will belong to the Sponsor. 
 If the supply of Units exceeds demand, or for 
some other business reason, the Sponsor may, 
without prior notice, at any time or 
occasionally from time to time discontinue the 
repurchase of Units of this Series at the 
Sponsor's Repurchase Price. In such event, 
although under no obligation to do so, the 
Sponsor may, as a service to Unitholders, offer 
to repurchase Units at the "Redemption Value". 
If the Sponsor repurchases Units in the 
secondary market at the "Redemption Value", it 
may reoffer these Units in the secondary market 
at the "Public Offering Price". In no event will 
the price offered by the Sponsor for the 
repurchase of Units be less than the current 
Redemption Value for those Units. See 
"Redemption of Units by Trustee" and "Comparison 
of Public Offering Price and Redemption Value".

ESTIMATED CURRENT RETURN AND ESTIMATED LONG TERM 
RETURN
 The Sponsor may from time to time give 
investors Estimated Current Return and Estimated 
Long Term Return information, each of which give 
investors different information about the 
return. Estimated Current Return on a Unit 
represents annual cash receipts from coupon-
bearing debt obligations in the Trust (after 
estimated annual expenses) divided by the Public 
Offering Price (including the sales charge). 
 Unlike Estimated Current Return, Estimated Long 
Term Return is a measure of the estimated return 
to the investor earned over the estimated life 
of the Trust. 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 Securities in the Trust and (2) takes into 
account the expenses and maximum sales charge 
associated with each Unit. The Estimated Long 
Term Return calculation does not take into 
account certain delays in distributions of 
income and the timing of other receipts and 
distributions on Units and may, depending on 
maturities, over or understate the impact of 
sales charges. Both of these factors may result 
in a lower figure. 
 Both Estimated Current Return and Estimated 
Long Term Return are subject to fluctuation with 
changes in Trust composition, changes in market 
value of the underlying Securities and changes 
in fees and expenses, including sales charges. 
The size of any difference between Estimated 
Current Return and Estimated Long Term Return 
can also be expected to fluctuate at least as 
frequently. In addition, both return figures may 
not be directly comparable to yield figures used 
to measure other investments, and, since the 
return figures are based on certain assumptions 
and variables, the actual returns received by a 
Unitholder may be higher or lower.

ESTIMATED NET ANNUAL INTEREST INCOME PER UNIT
 The estimated Net Annual Interest Income per 
Unit of the Trust is computed by dividing the 
total gross annual interest income to the Trust 
by the number of Units outstanding and then 
subtracting the per Unit estimated annual fees 
and expenses of the Trustee, the Sponsor and the 
Evaluator (see "Essential Information" in Part 
A). The estimated Net Annual Interest Income per 
Unit will be higher for Unitholders who do not 
elect the monthly plan (where alternate plans of 
distribution are available). This is the result 
of the differing expenses and fees of the 
Trustee in administering the distributions of 
interest. See "Essential Information" in Part A 
and "Distributions to Unitholders". 
 The estimated Net Annual Interest Income per 
Unit will change whenever Securities mature, are 
called for redemption, or are sold. In addition, 
any change in the Trustee's, the Sponsor's 
(where applicable) or Evaluator's fees or 
expenses will result in a change in the 
estimated Net Annual Interest Income per Unit 
(see "Expenses of the Trust").

            DISTRIBUTIONS TO UNITHOLDERS
 The Trustee will collect the interest on the 
Securities as it becomes payable and credit such 
interest to a separate Interest Account created 
by the Indenture. All moneys received by the 
Trustee from sources other than interest will be 
credited to a separate Principal Account. All 
funds collected or received will be held by the 
Trustee in trust without interest to Unitholders 
as part of the Trust or the Reserve Account 
referred to below until required to be disbursed 
in accordance with the provisions of the 
Indenture. Such funds will be segregated by 
separate recordation on the Trust ledger of the 
Trustee so long as such practice preserves a 
valid preference under applicable law, or, if 
such preference is not preserved the Trustee 
shall handle such funds in such other manner as 
shall constitute the segregation and holding 
thereof in trust within the meaning of the 
Investment Company Act of 1940, as the same may 
be from time to time amended. To the extent 
permitted by the Indenture and applicable 
banking regulations, such funds are available 
for use by the Trustee pursuant to normal 
banking procedures.
 The Trustee is authorized by the Indenture to 
withdraw from the Principal and/or Interest 
Accounts such amounts as it deems necessary to 
establish a reserve for any taxes or other 
governmental charges that may be payable out of 
the Trust, which amounts will be deposited in a 
separate Reserve Account. If the Trustee 
determines that the amount in the Reserve 
Account is greater than the amount necessary for 
payment of any taxes or other governmental 
charges, it will promptly deposit the excess in 
the Account from which it was withdrawn.
 The settlement date for the purchase of Units 
must occur on or prior to the Record Date in 
order for a purchaser to receive a distribution 
on the next Distribution Date. If the settlement 
date for the purchase of Units occurs after the 
Record Date, distribution will not occur until 
the second following Distribution Date. 

Interest Account 
 After deduction of the fees and expenses of the 
Trustee, the Sponsor (where applicable and as 
indicated under "Essential Information") and the 
Evaluator, the Trustee will distribute on each 
Distribution Date or shortly thereafter, to 
Unitholders of record on the preceding Record 
Date, an amount approximately equal to either 
one-twelfth, one-quarter or one-half of such 
Unitholder's pro rata share (depending on the 
distribution plans available and selected) of 
the estimated annual amount to be deposited in 
the Interest Account, computed as of the 
preceding Record Date. However, all Unitholders 
of record on the initial Record Date will 
receive the initial interest distribution on the 
initial Interest Distribution Date. The 
Trustee's fees and expenses will be higher for 
monthly interest distributions than for 
quarterly or semi-annual interest distributions, 
where available. Therefore, the amount 
distributed per Unit to Unitholders electing the 
monthly plan will be correspondingly lower than 
under the quarterly or semi-annual plan. All 
interest distributions following the initial 
interest distribution will be in approximately 
the amounts shown under "Essential Information", 
depending on the plan of distribution selected. 
See "Essential Information--Plan of 
Distribution" in Part A for details on electing 
available distribution plans. 
 Because the Securities in the Trust pay 
interest at varying semi-annual intervals and 
Units pay interest at constant monthly, 
quarterly or semi-annual intervals, the interest 
accrued on Units of the Trust will be greater 
than the amount available for distribution from 
the Interest Account. The Trustee will 
distribute on each Distribution Date an amount 
which will be less than the interest accrued to 
each Unitholder on the preceding Record Date. 
Pursuant to the Indenture, in order to 
accommodate regular interest distributions, the 
Trust will contain undistributed cash balances. 
The difference between the amount accrued to 
each Unitholder on a Record Date and the amount 
distributed on the following Distribution Date 
is an asset of the Unitholder and will be 
included as part of accrued interest which will 
be received in subsequent interest 
distributions, upon the sale of his Units or, in 
part, upon the sale, redemption, or maturity of 
Securities in the Trust. 
 The Trustee is authorized by the Indenture to 
advance such amounts as may be necessary to 
provide interest distributions of approximately 
equal amounts in accordance with the 
distribution plan selected. The Trustee will be 
reimbursed, without interest, for any such 
advances in the manner provided in the 
Indenture. 

Principal Account 
 The Trustee will distribute an amount equal to 
such Unitholder's pro rata share of the cash 
balance, if any, in the Principal Account on the 
principal Distribution Date specified under 
"Distribution" under "Essential Information". 
The pro rata share is computed as of the 
preceding Record Date. Except for moneys used to 
redeem tendered Units, proceeds received upon 
the disposition of any Securities subsequent to 
a Record Date and prior to the following 
principal Distribution Date will be held in the 
Principal Account and will not be distributed 
until the next succeeding principal Distribution 
Date. However, in the event of an early 
redemption of bonds, sale of bonds upon the 
occurrence of events set forth under 
"Supervision of Trust Investments", or maturity 
of bonds, there may occur a special principal 
distribution. Any special principal distribution 
will be made within 60 days of such event to 
Unitholders of record on the Record Date 
selected therefor by the Trustee as provided in 
the Indenture. No distribution need be made from 
the Principal Account if the cash balance 
therein is less than one-tenth of one per cent 
of the total principal amount of the Securities 
on the Initial Date of Deposit. 
 Certain of the Bonds in the Trust are subject 
to sinking fund or special redemption by their 
issuers, as set forth under "Redemption 
Features" on the "Schedule of Investments in 
Part A". The redemption price of Bonds in the 
Trust called by an issuer pursuant to sinking 
fund or special redemption is normally equal to 
the principal amount of such Bonds, while the 
redemption price for Bonds called at the option 
of the issuer may include a redemption premium. 
In most cases Bonds are selected from among 
Bonds of like series and maturity either by lot 
or by such method as the bond trustee may adopt. 
A capital gain or loss may occur depending upon 
the price at which a Bond which is called was 
acquired by the Trust and the amount received by 
the Trust upon redemption (see "Tax Status of 
the Trust"). In general, optional redemption 
provisions are more likely to be exercised by an 
issuer when the offering side valuation is 
greater than par than when the offering side 
valuation is less than par. If future interest 
rates decline, an issuer of Bonds might find it 
advantageous to exercise its option to call 
Bonds prior to maturity even though, in most 
cases, the issuer must pay a premium. 
Reinvestment Program 
 Distributions are made to Unitholders monthly. 
The Unitholder has the option of receiving the 
monthly interest and/or principal distribution 
or reinvesting at net asset value in the 
PaineWebber Tax-Exempt Income Fund (the "Fund"), 
an open-end investment company registered under 
the Investment Company Act. The Fund's 
investment objective is to provide high current 
income exempt from Federal income tax, 
consistent with the preservation of capital and 
liquidity within the Fund's quality standards. 
Except under unusual market conditions, the Fund 
will invest at least 80% of its assets in 
municipal obligations with varying maturities, 
the interest from which, in the opinion of bond 
counsel to their respective issuers, is exempt 
from both Federal income tax and the Federal 
alternative minimum tax. There can be no 
assurance that the Fund will achieve its 
objective. For more information about the Fund, 
including a prospectus, Unitholders should 
contact their PaineWebber Investment Executive 
or call the Fund's shareholder service number at 
1-800-544-9300. 
 To participate in the Reinvestment Program, 
Unitholders must hold Units in their own name, 
must fill out an application establishing an 
account and notify the Trustee of the account 
number at least 10 days before the Record Date. 
Elections may be revoked upon similar notice.

EXCHANGE OPTION
 Unitholders may elect to exchange any or all of 
their Units of this series for units of one or 
more of any series of PaineWebber Municipal Bond 
Fund First Series; PaineWebber Municipal Bond 
Fund Second Series; PaineWebber Municipal Bond 
Fund Third Series (the "PaineWebber Series"); 
The Municipal Bond Fund, Series One through 
Series Forty-Three; The Municipal Bond Trust, 
Series Forty-Four and subsequent series (the 
"National Series"); The Municipal Bond Trust, 
Multi-State Program Series One and subsequent 
series (the "Multi-State Series); The Municipal 
Bond Trust, California Series A and subsequent 
series (the "California Series"); The Municipal 
Bond Trust, Insured Series One and subsequent 
series (the "Insured Series"); The Corporate 
Bond Trust, Series One and subsequent series 
(the "Corporate Series"); The PaineWebber 
Pathfinders Trust, Treasury and Growth Stock, 
Series 1 and subsequent series (the "Pathfinders 
Trust"), the PaineWebber Federal Government 
Trust, GNMA Series 1 and subsequent Series 1 
(the "Federal Government Trust") or the 
PaineWebber Equity Trust, Growth Stock Series 1 
and subsequent series (the "Equity Trust") 
(collectively referred to as the "Exchange 
Trusts"), at a Public Offering Price for the 
units of the Exchange Trusts to be acquired 
based on a reduced sales charge of $15 per unit. 
The purpose of such reduced sales charge is to 
permit the Sponsor to pass on to the Unitholder 
who wishes to exchange Units the cost savings 
resulting from such exchange of Units. The cost 
savings result from reductions in time and 
expense related to advice, financial planning 
and operational expense required for the 
Exchange Option. Each Exchange Trust has 
different investment objectives, therefore a 
Unitholder should read the prospectus for the 
applicable Exchange Trust carefully prior to 
executing this option. Exchange Trusts having as 
their objective the receipt of tax exempt 
interest income would not be suitable for tax 
deferred investment plans such as Individual 
Retirement Accounts. A Unitholder who purchased 
Units of a series and paid a per unit sales 
charge that was less than the per Unit sales 
charge of the series of Exchange Trusts for 
which such Unitholder desires to exchange into, 
will be allowed to exercise the Exchange Option 
at the Unit Offering Price plus the reduced 
sales charge, provided the Unitholder has held 
the Units for at least five months. Any such 
Unitholder who has not held the Units to be 
exchanged for the five-month period will be 
required to exchange them at the Unit Offering 
Price plus a sales charge based on the greater 
of the reduced sales charge, or an amount which, 
together with the initial sales charge paid in 
connection with the acquisition of the Units 
being exchanged, equals the sales charge of the 
series of the Exchange Trust for which such 
Unitholder desires to exchange into, determined 
as of the date of the exchange. 
 The Sponsor will permit exchanges at the 
reduced sales charge provided there is a 
secondary market maintained by the Sponsor in 
both the Units of this series and units of the 
applicable Exchange Trust and there are units of 
the applicable Exchange Trust available for 
sale. While the Sponsor has indicated that it 
intends to maintain a market for the units of 
the respective Trusts, there is no obligation on 
its part to maintain such a market. Therefore, 
there is no assurance that a market for units 
will in fact exist on any given date at which a 
Unitholder wishes to sell his Units of this 
series and thus there is no assurance that the 
Exchange Option will be available to a 
Unitholder. Exchanges will be effected in whole 
units only. Any excess proceeds from 
Unitholders' units being surrendered will be 
returned. Unitholders will be permitted to 
advance new money in order to complete an 
exchange. 
 An exchange of units pursuant to the Exchange 
Option will normally constitute a "taxable 
event" under the Code, i.e., a Unitholder will 
recognize a tax gain or loss which will be of a 
capital or ordinary nature depending upon among 
other things the length of time such Unitholder 
has held the Units. However, Unitholders are 
advised to consult their own tax advisors as to 
the tax consequences of exchanging units in 
their particular case. 
 The Sponsor reserves the right to modify, 
suspend or terminate this plan at any time 
without further notice to Unitholders. In the 
event the Exchange Option is not available to a 
Unitholder at the time he wishes to exercise it, 
the Unitholder will be immediately notified and 
no action will be taken with respect to his 
Units without further instruction from the 
Unitholder.
 To exercise the Exchange Option, a Unitholder 
should notify the Sponsor of his desire to 
exercise the Exchange Option and to use the 
proceeds from the sale of his Units of this 
series to purchase units of one or more of the 
Exchange Trusts. If units of the applicable 
outstanding series of the Exchange Trust are at 
that time available for sale, and if such units 
may lawfully be sold in the state in which the 
Unitholder is resident, the Unitholder may 
select the series or group of series for which 
he desires his investment to be exchanged. The 
Unitholder will be provided with a current 
prospectus or prospectuses relating to each 
series in which he indicates interest. 
 The exchange transaction will operate in a 
manner essentially identical to any secondary 
market transaction, i.e., Units will be 
repurchased at a price based on the aggregate 
bid price per Unit of the securities in the 
portfolio of the Trust. Units of the Exchange 
Trust, however, will be sold to the Unitholder 
at a reduced sales charge. Units sold under the 
Exchange Option will be sold at the bid prices 
per unit of the underlying securities in the 
particular portfolio involved plus a fixed 
charge of $15 per unit. Exchange transactions 
will be effected only in whole units; thus, any 
proceeds not used to acquire whole units will be 
paid to the selling Unitholder.
 For example, assume that a Unitholder, who has 
three units of a trust with a current price of 
$1,030 per unit based on the bid prices of the 
underlying securities, desires to sell his units 
and seeks to exchange the proceeds for units of 
a series of an Exchange Trust with a current 
price of $890 per unit based on the bid prices 
of the underlying securities. In this example, 
which does not contemplate rounding up to the 
next highest number of units, the proceeds from 
the Unitholder's units will aggregate $3,090. 
Since only whole units of an Exchange Trust may 
be purchased under the Exchange Option, the 
Unitholder would be able to acquire three units 
in the Exchange Trust for a total cost of $2,715 
($2,670 for the units and $45 for the sales 
charge). The remaining $375 would be returned to 
the Unitholder in cash.

               CONVERSION OPTION
 Owners of units of any registered unit 
investment trust sponsored by others which was 
initially offered at a maximum applicable sales 
charge of at least 3.0% ( a `Conversion Trust') 
may elect to apply the cash proceeds of the sale 
or redemption of those units directly to acquire 
available units of any Exchange Trust at a 
reduced sales charge of $15 per Unit, per 100 
Units in the case of Exchange Trusts having a 
Unit price of approximately $10, or per 1,000 
Units in the case of Exchange Trusts having a 
Unit price of approximately $1, subject to the 
terms and conditions applicable to the Exchange 
Option (except that no secondary market is 
required for Conversion Trust units). To 
exercise this option, the owner should notify 
his retail broker. He will be given a prospectus 
for each series in which he indicates interest 
and for which units are available. The dealer 
must sell or redeem the units of the Conversion 
Trust. Any dealer other than PaineWebber must 
certify that the purchase of units of the 
Exchange Trust is being made pursuant to and is 
eligible for the Conversion Option. The dealer 
will be entitled to two-thirds of the applicable 
reduced sales charge. The Sponsor reserves the 
right to modify, suspend or terminate the 
Conversion Option at any time without further 
notice, including the right to increase the 
reduced sales charge applicable to this option 
(but not in excess of $5 more per Unit, per 100 
Units or per 1,000 Units, as applicable than the 
corresponding fee then being charged for the 
Exchange Option). For a description of the tax 
consequences of a conversion reference is made 
to the Exchange Option section herein.

EXPENSES OF THE TRUST
 The cost of the preparation and printing of the 
Certificates, the Indenture and this Prospectus, 
the initial fees of the Trustee and the 
Trustee's counsel, the Evaluator's fees during 
the initial offering period, advertising 
expenses and expenses incurred in establishing 
the Trust, including legal and auditing fees, 
are paid by the Sponsor and not by the Trust. 
The Sponsor will receive no fee from the Trust 
for its services as Sponsor. 
 The Sponsor's fee, deducted only in trusts 
where the Initial Date of Deposit is on or after 
November 30, 1982, which is earned for portfolio 
supervisory services, is based upon the 
aggregate face amount of Bonds in the Trust at 
the beginning of each annual period. The 
Sponsor's fee, which is not to exceed the amount 
set forth under "Essential Information" in Part 
A, may exceed the actual costs of providing 
portfolio supervisory services for this Trust, 
but at no time will the total amount the Sponsor 
receives for portfolio supervisory services 
rendered to all series of the Municipal Bond 
Trust in any calendar year exceed the aggregate 
cost to it of supplying such services in such 
year. 
 For services performed under the Indenture, the 
Trustee will be paid by the Trust at the rate 
per $1,000 of principal amount of Securities in 
the Trust set forth under "Essential 
Information" in Part A. Such compensation will 
be computed monthly, quarterly or semi-annually 
(depending on available plans of distribution) 
on the basis of the greatest principal amount of 
the Securities in the Trust at any time during 
the preceding monthly or semi-annual period. 
 In no event will the Trustee be paid less than 
$2,000 in any one year. The Evaluator's fee for 
each daily evaluation is set forth under 
"Essential Information" in Part A. The fees of 
the Evaluator will be payable by the Trust. See 
"Essential Information" in Part A for the 
estimated annual fees and expenses per Unit 
under the various optional interest distribution 
plans. 
 The Sponsor's fee is payable annually, 
Trustee's fees are payable monthly, quarterly 
and semi-annually (depending on available plans 
of distribution) and the Evaluator's fees are 
payable monthly on or before each Distribution 
Date from the Interest Account, to the extent 
funds are available, then from the Principal 
Account. Any of such fees may be increased 
without approval of the Unitholders by an amount 
not exceeding a proportionate increase in the 
category entitled "All Services Less Rent" in 
the Consumer Price Index published by the United 
States Department of Labor. 
 In addition to the above, the following charges 
are or may be incurred by the Trust and paid 
from the Interest Account, or, to the extent 
funds are not available in such Account, from 
the Principal Account: (1) fees for the Trustee 
for extraordinary services; (2) expenses of the 
Trustee (including legal and auditing expenses) 
and of counsel; (3) various governmental 
charges; (4) expenses and costs of any action 
taken by the Trustee to protect the Trust and 
the rights and interests of the Unitholders; (5) 
indemnification of the Trustee for any loss, 
liabilities or expenses incurred by it in the 
administration of the Trust without negligence, 
bad faith or willful misconduct on its part; and 
(6) expenses incurred in contacting Unitholders 
upon termination of the Trust. The fees and 
expenses set forth above are payable out of the 
Trust and when unpaid will be secured by a lien 
on the Trust. 
 The accounts of certain Trusts may be audited 
not less than annually by independent public 
accountants selected by the Sponsor. The 
expenses of the audit shall be an expense of the 
Trust. So long as the Sponsor maintains a 
secondary market, Sponsor will bear any audit 
expense which exceeds 50 cents per Unit. 
Unitholders covered by the audit (if any) during 
the year may receive a copy of the audited 
financials upon request.

DESCRIPTION OF CERTIFICATES
 Ownership of Units is evidenced by registered 
Certificates, executed by the Trustee and the 
Sponsor, issued in denominations of one Unit or 
any integral multiple thereof. A Unitholder may 
transfer its Certificate by presenting it to the 
Trustee at its corporate trust office. Such 
Certificate must be properly endorsed or 
accompanied by a written instrument or 
instruments of transfer executed by the 
Unitholder or its duly authorized attorney. A 
Unitholder may be required to pay $2.00 per 
Certificate transferred to cover the Trustee's 
costs in implementing such transfer and to pay 
any tax or other governmental charge that may be 
imposed in connection with any such transfer. 
The Trustee is required to execute and deliver a 
new Certificate in exchange and substitution for 
any Certificate mutilated, destroyed, stolen or 
lost, if and when the Unitholder furnishes the 
Trustee with proper identification and 
satisfactory indemnity, and pays such expenses 
as the Trustee may reasonably incur. Any 
mutilated Certificate must be presented to the 
Trustee before any substitute Certificate will 
be issued.

STATEMENTS TO UNITHOLDERS
 With each distribution from the Interest and 
Principal Accounts, the Trustee will furnish 
each Unitholder with a statement setting forth 
the amount being distributed from each Account 
expressed as a dollar amount per Unit. 
 Promptly after the end of each calendar year, 
the Trustee will furnish to each person who at 
any time during the calendar year was a 
registered Unitholder a statement setting forth: 
 1. As to the Interest Account: 
 (a) the amount of interest received on the 
Securities and the percentage of such amount by 
states and territories in which the issuers of 
the Bonds are located; 
 (b) the amount paid from the Interest Account 
representing accrued interest for any 
Certificates redeemed; 
 (c) the deductions from the Interest Account 
for fees and expenses of the Trustee, the 
Sponsor and the Evaluator or for other various 
fees, charges or expenses relating to the Trust; 
 (d) the deductions from the Interest Account 
for payment into the Reserve Account; and 
 (e) the net amount remaining after such 
payments and deductions expressed as a total 
dollar amount outstanding on the last business 
day of such calendar year. 
 2. As to the Principal Account: 
 (a) the dates of the redemption, sale or 
maturity of any of the Securities and the net 
proceeds received therefrom, excluding any 
portion credited to the Interest Account; 
 (b) the amount paid from the Principal Account 
representing the principal of any Certificates 
redeemed; 
 (c) the deductions from the Principal Account 
for fees and expenses of the Trustee, the 
Sponsor and the Evaluator or for other various 
fees, charges or expenses relating to the Trust; 
 (d) the deductions from the Principal Account 
for payment into the Reserve Account; and 
 (e) the net amount remaining after such 
payments and deductions expressed as a total 
dollar amount outstanding on the last business 
day of such calendar year. 
 3. The following information: 
 (a) a list of the Securities as of the last 
business day of such calendar year; 
 (b) the number of Units outstanding on the last 
business day of such calendar year; 
 (c) the Unit Value based on the last evaluation 
of the Trust made on the last business day 
during such calendar year; and 
 (d) the amounts actually distributed during 
such calendar year from the Interest and 
Principal Accounts, separately stated, expressed 
both as total dollar amounts and as dollar 
amounts per Unit outstanding on the Record Dates 
for such distributions.

            REDEMPTION OF UNITS BY TRUSTEE
 A Unitholder who wishes to dispose of its Units 
should inquire through its broker as to the 
current market price for such Units prior to 
making a tender for redemption to the Trustee in 
order to determine if there is a market for 
Units in excess of the then current Redemption 
Value or Sponsor's Repurchase Price. After the 
initial offering period the Redemption Value 
will be the same as the Sponsor's Repurchase 
Price. 
 During the period in which the Sponsor 
maintains a secondary market for Units at the 
Sponsor's Repurchase Price, the Sponsor has 
agreed to repurchase any Unit presented for 
tender to the Trustee for redemption no later 
than the close of business on the second 
business day following such presentation. 
 The Trustee is irrevocably authorized in its 
discretion, in lieu of redeeming Units presented 
for tender at the redemption value, to sell such 
Units in the over-the-counter market for the 
account of a tendering Unitholder at prices 
which will return to the Unitholder amounts in 
cash, net after brokerage commissions, transfer 
taxes and other charges, equal to or in excess 
of the Redemption Value for such Units. In the 
event of any such sale the Trustee will pay the 
net proceeds thereof to the Unitholder on the 
day he would otherwise be entitled to receive 
payment of the Redemption Value.
 One or more Units represented by a Certificate 
may be redeemed at the Redemption Value upon 
tender of such Certificate to the Trustee at its 
corporate trust office, properly endorsed or 
accompanied by a written instrument of transfer 
in form satisfactory to the Trustee, and 
executed by the Unitholder or its authorized 
attorney. A Unitholder may tender its Units for 
redemption at any time after the settlement date 
for purchase, whether or not it has received a 
definitive Certificate. The Redemption Value per 
Unit is calculated by dividing the current bid 
prices for the Securities in the Trust (see 
"Evaluation of the Trust") plus any money in the 
Principal Account other than money required to 
redeem tendered Units, by the number of Units 
outstanding, plus a proportionate share of 
accrued interest and undistributed interest 
income on the Securities determined to the day 
of tender. There is no sales charge incurred 
when a Unitholder tenders his Units to the 
Trustee for redemption. Subject to the payment 
of any applicable tax or governmental charges, 
the Redemption Value of Units redeemed by the 
Trustee will be paid on the seventh calendar day 
following the day of tender. If such day of 
payment is not a business day, the Redemption 
Value will be paid on the first business day 
prior thereto. 
 The Trustee may, in its discretion, and will 
when so directed by the Sponsor, suspend the 
right of redemption, or postpone the date of 
payment of the Redemption Value, for more than 
seven calendar days following the day of tender 
for any period during which the New York Stock 
Exchange, Inc. is closed other than for weekend 
and holiday closings; or for any period during 
which the Securities and Exchange Commission 
determines that trading on the New York Stock 
Exchange, Inc. is restricted or for any period 
during which an emergency exists as a result of 
which disposal or evaluation of the Securities 
is not reasonably practicable; or for such other 
period as the Securities and Exchange Commission 
may by order permit for the protection of 
Unitholders. The Trustee is not liable to any 
person or in any way for any loss or damages 
which may result from any such suspension or 
postponement.
 Any amounts paid on redemption representing 
interest will be withdrawn from the Interest 
Account to the extent that funds are available 
for such purpose. All other amounts paid on 
redemption will be withdrawn from the Principal 
Account. The Trustee is empowered to sell 
Securities out of the Trust as selected by the 
Sponsor in order to make funds available for the 
redemption of Certificates, and, to the extent 
Securities are sold for such purpose, the size 
and diversity of the Trust will be reduced. Such 
sales may be required at a time when Securities 
would not otherwise be sold and may result in 
lower prices than might otherwise be realized. 
In addition, because of the minimum principal 
amount in which Securities may be required to be 
sold, the proceeds of such sales may exceed the 
amount necessary for payment of Units redeemed. 
Such excess proceeds will be distributed pro 
rata to all remaining Unitholders of record.

              EVALUATION OF THE TRUST
 The Evaluator is Kenny Information Systems, a 
division of J.J. Kenny Co., Inc., 65 Broadway, 
New York, New York 10006. 
 The value of the Trust is computed as of the 
Evaluation Time shown under "Essential 
Information" in Part A (1) on each June 30 and 
December 31 (or the last business day prior 
thereto), (2) on each business day as long as 
the Sponsor is maintaining a bid in the 
secondary market, (3) on the day on which any 
Unit is tendered for redemption and (4) on any 
other day desired by the Sponsor or the Trustee, 
by adding:
 1. The aggregate value of Securities in the 
Trust, as determined by the Evaluator: 
 (a) on the basis of current bid prices for the 
Securities, 
 (b) on the basis of current bid prices for 
comparable bonds, if bid prices are not 
available for any of the Securities, 
 (c) by determining the value of the Securities 
on the bid side of the market by appraisal, or 
 (d) by any combination of the above; 
 2. Money on hand in the Trust, other than money 
deposited to purchase Securities or money 
credited to the Principal Account which is 
required to redeem tendered Units; and 
 3. Accrued but unpaid interest on the 
Securities at the close of business on the date 
of such Evaluation. 
 The Trustee will deduct from the resulting 
figure: amounts representing any applicable 
taxes or governmental charges payable by the 
Trust for the purpose of making an addition to 
the Reserve Account; amounts representing 
estimated accrued expenses of the Trust; amounts 
representing unpaid fees of the Trustee, the 
Sponsor and the Evaluator; and cash held for 
distribution to Unitholders of record as of the 
business day prior to the Evaluation being made 
on the days or dates set forth above. 
 For the purpose of the redemption of Units, the 
value per Unit is computed by the Trustee by 
dividing the result of the above computation by 
the total number of Units outstanding on the 
date of such Evaluation.

COMPARISON OF PUBLIC OFFERING PRICE AND REDEMPTION VALUE
 While the Public Offering Price of Units during 
the initial offering period is determined on the 
basis of the current offering prices of the 
Securities, the Public Offering Price of Units 
in the secondary market and the Redemption Value 
is determined on the basis of the current bid 
prices of such Securities. On the date of the 
"Essential Information" page, the Public 
Offering Price per Unit (which figure includes 
the sales charge) exceeded the Redemption Value 
by the amount shown under "Essential 
Information" in Part A. The difference between 
the bid and offering prices of the Securities is 
expected to average 1-1/2% to 2% of principal 
amount. This difference may vary between 3% or 
more of principal amount for inactively traded 
Securities and as little as 1/2 of 1% for 
actively traded Securities. For this reason and 
others, including the fact that the Public 
Offering Price includes the sales charge, the 
amount realized by a Unitholder upon redemption 
of Units may be less than the price paid by the 
Unitholder for such Units.

           SUPERVISION OF TRUST INVESTMENTS
 The acquisition by the Trust of any securities 
other than the Securities initially deposited is 
prohibited by the Indenture. The Sponsor may 
direct the Trustee to sell or liquidate any of 
the Securities upon the happening of any of the 
following events (except for the limited right 
to replace securities in the case of a fail):
 1. Default by an issuer in the payment of 
principal of or interest on such Securities, or 
any other outstanding obligations of such 
issuer, when due and payable, 
 2. Institution of legal proceedings seeking to 
restrain or enjoin the payment of any of the 
Securities or attacking their validity,
 3. A breach of a covenant or warranty which 
could adversely affect the payment of debt 
service on the Securities,  4. In the case of 
revenue bonds, if the revenues, based upon 
official reports, fall substantially below the 
estimated revenues calculated to be necessary to 
pay principal of and interest on the Bonds,
 5. A decline in market price, or such other 
market or credit factor, as in the opinion of 
the Sponsor would make retention of any of the 
Securities detrimental to the Unitholders, or 
 6. In the event that any of the Bonds are the 
subject of an advance refunding.
 In addition, if a default in the payment of 
principal of or interest on any of the 
Securities occurs and the Sponsor fails to 
instruct the Trustee to sell or hold such 
Securities within thirty days after notification 
by the Trustee to the Sponsor of such default, 
the Indenture provides that the Trustee will 
sell the defaulted Securities promptly. The 
Trustee will not be liable or responsible in any 
way for depreciation or loss incurred by reason 
of any sale made by it either pursuant to a 
direction of the Sponsor or by reason of a 
failure of the Sponsor to give any such 
direction. 
 The Sponsor is required to 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 of the Bonds pursuant 
to a refunding or refinancing plan; however, the 
Sponsor may instruct the Trustee to accept or 
reject such an offer or to take any other action 
with respect thereto as the Sponsor deems proper 
if the issuer is in default with respect to the 
Securities or the issuer will, in the written 
opinion of the Sponsor, probably default with 
respect to the Bonds in the reasonably 
foreseeable future. 
 Any obligations received by the Trust in the 
event of such an exchange or substitution will 
be held by the Trustee and will be subject to 
the terms and conditions of the Indenture to the 
same extent as the Securities originally 
deposited. Within five days after any exchange 
and deposit, notice of such will be mailed by 
the Trustee to each registered Unitholder, which 
identifies the Securities eliminated and the 
Securities substituted.

             ADMINISTRATION OF THE TRUST
 Records and Accounts: Pursuant to the 
Indenture, the Trustee is required to keep 
proper books of record and account of all 
transactions relating to the Trust at its 
office. Such records will include the name and 
address of every Unitholder, a list of the 
Certificate numbers and the number of Units of 
each Certificate issued to Unitholders. The 
Trustee is also required to keep a certified 
copy or duplicate original of the Indenture and 
a current list of Securities held in the Trust 
on file at its office which will be open to 
inspection by any Unitholder during usual 
business hours.
 The Trustee is required to make annual or other 
reports as may from time to time be required 
under any applicable state or Federal statute, 
rule or regulation. 
 Successor Trustee: Under the Indenture, the 
Trustee may resign and be discharged of the 
Trust created by the Indenture by executing a 
notice of resignation in writing and filing it 
with the Sponsor. The resigning Trustee must 
also mail a copy of the notice of resignation to 
all Unitholders then of record, not less than 
sixty days before the effective resignation date 
specified in such notice. Such resignation will 
become effective only upon the appointment of 
and the acceptance of the Trust by a successor 
Trustee. The Sponsor, upon receiving notice of 
such resignation, is obligated to appoint a 
successor Trustee promptly. 
 If within thirty days after notice of 
resignation has been received by the Sponsor, no 
successor Trustee has been appointed or, if 
appointed, has not accepted the appointment, the 
resigning Trustee may apply to a court of 
competent jurisdiction for the appointment of a 
successor. In case the Trustee becomes incapable 
of acting as such or is adjudged a bankrupt or 
is taken over by any public authority, the 
Sponsor may discharge the Trustee and appoint a 
successor Trustee as provided in the Indenture. 
Notice of such discharge and appointment shall 
be mailed to each Unitholder by the Sponsor. 
 Upon a successor Trustee's execution of a 
written acceptance of an appointment as Trustee 
for the Trust, such successor Trustee will 
become vested with all the rights, powers, 
duties and obligations of the original Trustee. 
 A successor Trustee is required to be a 
corporation organized and doing business under 
the laws of the United States or of the State of 
New York; to be authorized under such laws to 
exercise corporate trust powers; to have at all 
times an aggregate capital, surplus and 
undivided profit of not less than $5,000,000; 
and to have its principal office in New York 
City. 
 Successor Sponsor: If at any time the Sponsor 
shall fail to undertake or perform or become 
incapable of undertaking or performing any of 
the duties which by the terms of the Indenture 
are required of it to be undertaken or 
performed, or if the Sponsor resigns, the 
Trustee may either appoint a successor Sponsor 
or Sponsors as will be satisfactory to the 
Trustee or it may terminate the Indenture and 
liquidate the Trust. Any successor Sponsor may 
be compensated at rates deemed by the Trustee to 
be reasonable. 
 The dissolution of the Sponsor or its ceasing 
to exist as a legal entity from, or for, any 
cause whatsoever will not cause the termination 
of the Indenture or the Trust unless the Trustee 
deems termination to be in the best interests of 
Unitholders. 
 Successor Evaluator: The Evaluator may resign 
or may be removed by the Sponsor or the Trustee, 
and the Sponsor and the Trustee are to use their 
best efforts to appoint a satisfactory 
successor. Such resignation or removal will 
become effective upon the acceptance of 
appointment by a 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 Evaluator. Notice of 
such resignation or removal and appointment will 
be mailed by the Trustee to each Unitholder.

LIMITATION OF LIABILITIES
 The Sponsor: The Indenture provides that the 
Sponsor will not be liable to the Trustee, the 
Trust or the Unitholders for taking any action 
or for refraining from taking any action made in 
good faith or for errors in judgment, but will 
be liable only for its own willful misfeasance, 
bad faith, gross negligence or willful disregard 
of its duties. The Sponsor will not be liable or 
responsible in any way for depreciation or loss 
incurred by reason of the sale of any Securities 
in the Trust. 
 The Trustee: The Indenture provides that the 
Trustee will not be liable for any action taken 
in good faith in reliance on properly executed 
documents or for the disposition of moneys, 
Securities or Certificates, except by reason of 
its own gross negligence, bad faith or willful 
misconduct, nor will the Trustee be liable or 
responsible in any way for depreciation or loss 
incurred by reason of the sale by the Trustee of 
any Securities in the Trust. In the event of the 
failure of the Sponsor to act, the Trustee may 
act and will not be liable for any such action 
taken by it in good faith. The Trustee will not 
be personally liable for any taxes or other 
governmental charges imposed upon or in respect 
of the Securities or upon the interest thereon 
or upon it as Trustee or upon or in respect of 
the Trust 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. The 
Trustee will be indemnified and held harmless 
against any loss or liability accruing to 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, including the costs and expenses 
(including counsel fees) of defending itself 
against any claim of liability.
 The Evaluator: The Trustee, Sponsor, and 
Unitholders may rely on any evaluation furnished 
by the Evaluator and will have no responsibility 
for the accuracy thereof. The Indenture provides 
that the determinations made by the Evaluator 
will be made in good faith upon the basis of the 
best information available to it; provided, 
however, that the Evaluator will be under no 
liability to the Trustee, Sponsor or Unitholders 
for errors in judgment, but will be liable only 
for its gross negligence, lack of good faith or 
willful misconduct.

             AMENDMENT OF THE INDENTURE
 The Indenture may be amended by the Trustee and 
the Sponsor without the consent of any of the 
Unitholders to cure any ambiguity or to correct 
or supplement any provision thereof which may be 
defective or inconsistent or to make such other 
provisions as will not adversely affect the 
interest of the Unitholders; provided, however, 
that after the deposit of the Securities the 
Indenture may not be amended to increase the 
number of Units issued thereunder or to permit 
the deposit or acquisition of securities either 
in addition to or in substitution for any of the 
Securities initially deposited in the Trust, 
except for the substitution of certain refunding 
securities for the Securities. The Trustee will 
promptly notify Unitholders of the substance of 
any such amendment.

              RIGHTS OF UNITHOLDERS
 A Unitholder may at any time tender his 
Certificate to the Trustee for redemption. 
 The death or incapacity of any Unitholder will 
not operate to terminate the Trust nor entitle 
his legal representatives or heirs to claim an 
accounting or to take any action or proceeding 
in any court for a partition or winding up of 
the Trust. 
 No Unitholder will have the right to vote 
concerning the Trust, except with respect to 
termination, or in any manner control the 
operation and management of the Trust, nor shall 
any Unitholder ever be liable to any other 
person by reason of any action taken by the 
Sponsor or the Trustee.

             TERMINATION OF THE TRUST
 The Indenture provides that the Trust will 
terminate upon the maturity, redemption, sale or 
other disposition of the last of the Securities 
held in the Trust. If the value of the Trust as 
shown by any evaluation is less than twenty per 
cent (20%) of the par value of the Securities 
originally deposited in the Trust, the Trustee 
may in its discretion, and will when so directed 
by the Sponsor, terminate the Trust. The Trust 
may also be terminated at any time by the 
written consent of 100% of the Unitholders or by 
the Trustee upon the resignation or removal of 
the Sponsor if the Trustee determines 
termination to be in the best interest of the 
Unitholders. In no event will the Trust continue 
beyond the Mandatory Termination Date.
 Upon termination, the Trustee will sell the 
Securities then held in the Trust and credit the 
moneys derived from such sale to the Principal 
Account and the Interest Account. The Trustee 
will then, after deduction of any fees and 
expenses of the Trust and payment into the 
Reserve Account of any amount required for taxes 
or other governmental charges that may be 
payable by the Trust, distribute to each 
Unitholder, upon surrender for cancellation of 
his Certificate after due notice of such 
termination, such Unitholder's pro rata share in 
the Interest and Principal Accounts. The sale of 
Securities in the Trust upon termination may 
result in a lower amount than might otherwise be 
realized if such sale were not required at such 
time. For this reason, among others, the amount 
realized by a Unitholder upon termination may be 
less than the principal amount of Securities 
represented by the Units held by such 
Unitholder.

                BOND RATINGS*

Standard & Poor's Corporation 
 AAA_Debt rated AAA has the highest rating 
assigned by Standard & Poor's. Capacity to pay 
interest and repay principal is extremely 
strong.
 AA_Debt rated AA has a very strong capacity to 
pay interest and repay principal and differs 
from the highest rated issues only in small 
degree.
 A_Debt rated A has a strong capacity to pay 
interest and repay principal although it is 
somewhat more susceptible to the adverse effects 
of changes in circumstances and economic 
conditions than debt in higher rated categories.
 BBB_Debt rated BBB is regarded as having an 
adequate capacity to pay interest and repay 
principal. Whereas it normally exhibits 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 debt in this 
category than in higher rated categories.
 BB, B, CCC, CC_Debt rated BB, B, CCC, and CC is 
regarded, on balance, as predominately 
speculative with respect to capacity to pay 
interest and repay principal in accordance with 
the terms of the obligation. BB indicates the 
lowest degree of speculation and CC the highest 
degree of speculation. While such debt will 
likely have some quality and protective 
characteristics, these are outweighed by large 
uncertainties or major risk exposures to adverse 
conditions.
 The ratings from AA to CCC may be modified by 
the addition of a plus or minus sign to show 
relative standing within the major rating 
categories.
 A provisional rating, indicated by "p" 
following a rating, assumes the successful 
completion of the project being financed by the 
issuance of the debt 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.
 NR_Securities which, while not rated by 
Standard & Poor's or Moody's, have been 
determined by the trusts sponsor to be of 
investment grade quality.
_______________
 *As described by the rating agencies.

Moody's Investors Service, Inc. 
 Aaa_Bonds which are rated Aaa are judged to be 
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. 
 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. 
 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.
 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.
 Ba_Bonds which are rated Ba are judged to have 
speculative elements; their future cannot be 
considered as well assured. Often the protection 
of interest and principal payments may be very 
moderate and thereby not well safeguarded during 
both good and bad times over the future. 
Uncertainty of position characterizes bonds in 
this class. 
 B_Bonds which are rated B generally lack the 
characteristics of a desirable investment. 
Assurance of interest and principal payments or 
of maintenance of other terms of the contract 
over any long period of time may be small. 
 Caa_Bonds which are rated Caa are in poor 
standing. Such issues may be in default or there 
may be present elements of danger with respect 
to principal or interest. 
 Ca_Bonds which are rated Ca represent 
obligations which are speculative in a high 
degree. Such issues are often in default or have 
other marked shortcomings. 
 C_Bonds which are rated C are the lowest rated 
class of bonds and issues so rated can be 
regarded as having extremely poor prospects of 
ever attaining any real investment standing. 
 Rating symbols may include numerical modifiers 
1, 2 or 3. The numerical modifier 1 indicates 
that the security ranks at the high end, 2 in 
the mid-range, and 3 nearer the low end of the 
generic category. These modifiers of rating 
symbols Aa, A and Baa are to give investors a 
more precise indication of relative debt quality 
in each of the historically defined categories. 
 Conditional ratings, indicated by "Con" are 
given to bonds for which the security depends 
upon the completion of some act or the 
fulfillment of some condition. These are bonds 
secured by (a) earnings of projects under 
construction, (b) earnings of projects 
unseasoned in operating experience, (c) rentals 
which begin when facilities are completed, or 
(d) payments to which some other limiting 
condition attaches. A parenthetical rating 
denotes probable credit stature upon completion 
of construction or elimination of basis of such 
condition.

  April 22, 1998
  PaineWebber Incorporated
  1200 Harbor Blvd.
  Weehawken, New Jersey 07087
  Ladies and Gentlemen:
  We have served as counsel for PaineWebber Incorporated as
  sponsor and depositor (the "Depositor") of The Municipal Bond
  Trust, Series 224 and The Municipal Bond Trust, California Insured
  Series 7A (hereinafter referred to as the "Trust").
  It is proposed that Post-Effective Amendment No. 8 to the 
  Trust's registration statement ("Post-Effective Amendment No.8")
  will be filed with the Securities and Exchange Commission and
  dated as of the date hereof in connection with the continued
  issuance by the Trust of an indefinite number of units of
  fractional undivided interest in the Trust (hereinafter referred
  to as the "Units") pursuant to Rule 24f-2 promulgated under the
  provisions of the Investment Company Act of 1940, as amended.
  In this regard, we have examined executed originals or copies of the
  following:
  (a)  The Restated Certificate of Incorporation, as amended, and the
       By-Laws of the Depositor, as amended;
  (b)  Resolutions of the Board of Directors of the Depositor adopted on
       December 3, 1971 relating to the Trust and the sale of the Units;
  (c)  Resolutions of the Executive Committee of the Depositor adopted
       on September 24, 1984;
  (d)  Powers of Attorney referred to in the Amendment;
  (e)  Post-Effective Amendment No. 8 to the Registration Statement on
       Form S-6 (File Nos. 33-30270 and 33-25384) to be filed with the
       Securities and Exchange Commission (the "Commission") in
       accordance with the Securities Act of 1933, as amended, and the
       rules and regulations of the Commission promulgated thereunder
       (collectively, the "1933 Act") proposed to be filed on or about the
       date hereof (the "Amendment");
  (f)  The Notification of Registration of the Trust filed with the
       Commission under the Investment Company Act of 1940, as
       amended (collectively, the "1940 Act") on Form N-8A, as
       amended;
  (g)  The registration of the Trust filed with the Commission under the
       1940 Act on Form N-8B-2 (File No. 811-2599), as amended;
  (h)  The prospectus included in the Amendment (the "Prospectus");
  (i)  The Standard Terms and Conditions of the Trust dated as of
       January 15, 1988, as amended, among the Depositor, Investors
       Bank & Trust Company and the First National Bank of Chicago
       (the "Co-Trustees"), as successor Co-Trustee, and Standard &
       Poor's Corporation and Kenny Information Systems, a division of
       J.J. Kenny Co., Inc. (the "Evaluator") (the "Standard Terms");
  (j)  The Trust Indenture dated as of the Initial Date of Deposit, among
       the Depositor, the Co-Trustees and the Evaluator (the "Trust
       Indenture" and, collectively with the Standard Terms, the
       "Indenture and Agreement");
  (k)  The form of certificate of ownership for units (the "Certificate") to
       be issued under the Indenture and Agreement; and
  (l)  Such other pertinent records and documents as we have deemed
       necessary.
       With your permission, in such examination, we have assumed
  the following: (a) the authenticity of original documents and the
  genuineness of all signatures; (b) the conformity to the originals of
  all documents submitted to us as copies; (c) the truth, accuracy,
  and completeness of the information, representations, and warranties
  contained in the records, documents, instruments and certificates we
  have reviewed; (d) except as specifically covered in the opinions set
  forth below, the due authorization, execution, and delivery on behalf
  of the respective parties thereto of documents referred to herein and
  the legal, valid, and binding effect thereof on such parties; and (e)
  the absence of any evidence extrinsic to the provisions of the written
  agreement(s) between the parties that the parties intended a
  meaning contrary to that expressed by those provisions. However,
  we have not examined the securities deposited pursuant to the
  Indenture and Agreement (the "Securities") nor the contracts for the
  Securities.
       We express no opinion as to matters of law in jurisdictions other
  than the State of New York (except "Blue Sky" laws) and the federal laws
  of the United States, except to the extent necessary to render the 
  opinion as to the Depositor in paragraph (i) below with respect to 
  Delaware law.  As you know we are not licensed to practice law in the 
  State of Delaware, and our opinion in paragraph (i) and (iii) as to 
  Delaware law is based solely on review of the official statutes of the 
  State of Delaware.
       Based upon such examination, and having regard for legal
  considerations which we deem relevant, we are of the opinion that:
  (i)  The Depositor is a corporation duly organized, validly existing, and
       in good standing under the laws of the State of Delaware with full
       corporate power to conduct its business as described in the
       Prospectus;
  (ii) The Depositor is duly qualified as a foreign corporation and is in
       good standing as such within the State of New York;
  (iii)The terms and provisions of the Units conform in all material
       respects to the description thereof contained in the Prospectus;
  (iv) The consummation of the transactions contemplated under the
       Indenture and Agreement and the fulfillment of the terms thereof
       will not be in violation of the Depositor's Restated Certificate of
       Incorporation, as amended, or By-Laws, as amended and will not
       conflict with any applicable laws or regulations applicable to the
       Depositor in effect on the date hereof; and
  (v)  The Certificates to be issued by the Trust, when duly executed by
       the Depositor and the Trustee in accordance with the Indenture
       and Agreement, upon delivery against payment therefor as

  RE: The Municipal Bond Trust, California Insured Series 7A
  We have received the post-effective amendment to the registration
  statment SEC file number 33-25384 for the above captioned trust.
  Since the portfolio is composed solely of securities covered by bond
  insurance policies that insure against default in the payment of
  principal and interest on the securities for so long as they remain
  outstanding and such policies have been issued by one or more
  insurance companies which have been assigned 'AAA' claims paying
  ability rating by S&P, we reaffirm the assignment of a 'AAA' rating to
  the units of the trust and a 'AA' rating to the securities contained in
  the trust.
  You have permission to use the name Standard & Poor's
  Corporation 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 in the trust. Further, it should be understood that the
  rating of the units does not take into account the extent to which
  fund expenses or portfiolio asset sales for less than the fund's
  purchase price will reduce payment to the unitholders 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 Corporation in connection with the rating assigned to the
  units in the amendment referred to above. 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 and Poor's Corporation 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.
  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.
