MUNICIPAL TRUST
INSURED CALIFORNIA INTERMEDIATE TERM PORTFOLIO SERIES 10
Standard & Poor's Corporation Rating: AAA
(A Unit Investment Trust)
_______________________________________________________________
This Trust was formed for the purpose of providing interest
income which in the opinion of bond counsel is, under existing
law, excludable from gross income for Federal income tax
purposes (except in certain instances depending on the Unit
Holders) and is exempt from State of California income taxes to
individual Unit Holders resident in the State of California,
through investment in a fixed portfolio consisting primarily of
investment grade intermediate term state, municipal and public
authority debt obligations. The value of the Units of the
Trust will fluctuate with the value of the portfolio of
underlying Securities. The portfolio of the Trust was
structured as of the Date of Deposit to return to Unit Holders
each year beginning in 1999, approximately 20% of the per Unit
principal amount of the Securities included in the Trust.
(See: "Schedule of Portfolio Securities".) The Units of the
Trust are rated AAA by Standard & Poor's Corporation because
all of the Securities have been irrevocably insured by
insurance either provided by the respective Issuers thereof or
obtained by third parties. Minimum Purchase: $1,000.

SUMMARY OF ESSENTIAL INFORMATION
(Continued)
THE TRUST -- The Dean Witter Select Municipal Trust,
Insured California Intermediate Term Portfolio Series 10 (the
"Insured California Trust" or the "Trust") is a unit investment
trust which was created on August 26, 1993 (the "Date of
Deposit"), under the laws of the State of New York pursuant to
an Indenture as defined in Part B. The Trust is composed of
"investment grade" intermediate term interest bearing municipal
bonds (the "Securities"). (For a description of the meaning of
"investment grade" securities, see: "Bond Ratings", in
Part B.) The objectives of the Trust are: (1) the receipt of
income which, under existing law, is excludable from gross
income for Federal income tax purposes (except in certain
instances depending on the Unit Holders) and is exempt from
State of California income taxation to individual Unit Holders
resident in the State of California; and (2) the conservation
of capital. The portfolio of the Trust was structured as of
the Date of Deposit to return to Unit Holders each year
beginning in 1999, approximately 20% of the per Unit principal
amount of the Securities included in the Trust. (See:
"Schedule of Portfolio Securities".) The payment of interest
and the preservation of principal of the Trust is dependent on
the continuing ability of the respective Issuers of the
Securities or the bond insurers thereof to meet their
obligations to pay principal and interest on the Securities.
Therefore, there is no guarantee that the objectives of the
Trust will be achieved. All of the Securities in the Trust are
obligations of the State of California or of the counties,
municipalities or public authorities thereof. Interest on the
Securities, in the opinion of bond counsel or special tax
counsel to the Issuers thereof, under existing law, is
excludable from gross income for Federal income tax purposes
(except in certain instances depending on the Unit Holders) and
is exempt from State of California income taxes when owned by
individual Unit Holders resident in the State of California.
(For a discussion of certain tax aspects of the Trusts, see:
"Tax Status", in Part B. For a discussion of certain state tax
aspects of the Insured California Trust, see: "Special
Considerations Regarding California Securities -- California
Tax Status", herein.)
OFFERS TO SELL OR THE SOLICITATION OF ORDERS TO BUY
MAY ONLY BE MADE IN THOSE JURISDICTIONS IN WHICH THE UNITS OF
THE TRUST HAVE BEEN REGISTERED. INVESTORS SHOULD CONTACT
ACCOUNT EXECUTIVES OF THE SPONSOR TO DETERMINE WHETHER THE
UNITS OF THE TRUST HAVE BEEN REGISTERED FOR SALE IN THE STATE
IN WHICH THEY RESIDE.
INSURANCE -- A policy of insurance guaranteeing the
scheduled payment of principal and interest ("Bond Insurance")
A-4
<PAGE>
has been obtained from the bond insurers indicated on the
respective "Schedule of Portfolio Securities", herein, and paid
for by the Issuers of the Securities, or by third parties, for
all the Securities in the Insured California Trust. The
policies of Bond Insurance are non-cancellable and cover
default in the payment of principal and interest on the
Securities so insured so long as such Securities remain
outstanding, whether they are held in the Insured California
Trust or not. Bond Insurance on all Securities in the Insured
California Trust relates only to the Securities in such Trust
and not to the Units offered hereby. No representation is made
herein as to any bond insurer's ability to meet its obligations
under a policy of Bond Insurance relating to a Security in the
Insured California Trust. However, as a result of such Bond
Insurance, the Securities, as well as the Units of the Insured
California Trust, are rated "AAA" by Standard & Poor's
Corporation. There can be no assurance that such "AAA" ratings
will be retained. (See: "Insurance on the Securities in an
Insured Trust", in Part B.)
MONTHLY DISTRIBUTIONS -- Monthly distributions of
principal, premium, if any, and interest received by the Trust
will be made on or shortly after the fifteenth day of each
month to Unit Holders of record on the ninth day of such month.
Alternatively, Unit Holders may elect to have their monthly
distributions reinvested in either of the Reinvestment Programs
of the Sponsor, neither of which are insured. (See:
"Reinvestment Programs", in Part B.)
PUBLIC OFFERING PRICE -- The Public Offering Price
per Unit of the Trust is calculated daily, and is equal to the
aggregate bid side evaluation of the underlying Securities,
divided by the number of Units outstanding, plus a sales charge
calculated by reference to "Sales Charge/Volume Discount",
below, plus the per Unit balance in the Interest and Principal
Accounts. Units are offered at the Public Offering Price, plus
accrued interest. (See: "Public Offering of Units", in Part
B.)
ESTIMATED CURRENT RETURN -- The Estimated Current
Return shows the return based on the Public Offering Price and
is computed by multiplying the estimated net annual interest
rate per Unit (which shows the return based on a $1,000 face
amount) by $1,000 and dividing the result by the Public
Offering Price (not including accrued interest). The net
annual interest rate per Unit will vary with changes in the
fees and expenses of the Trustee, the Sponsor and the Evaluator
and with the exchange, redemption, sale or maturity of the
underlying Securities. In addition, the Public Offering Price
will also vary with fluctuations in the bid side evaluation of
the underlying Securities. Therefore, it can be expected that
the Estimated Current Return will fluctuate in the future.
A-5
<PAGE>
(See: "The Units -- Estimated Annual Income and Current
Return", in Part B.)
MARKET FOR UNITS -- The Sponsor, though not obligated
to do so, intends to maintain a market for the Units based on
the aggregate bid side evaluation of the underlying Securities,
as more fully described in Part B -- "Public Offering of Units
- -- Secondary Market". If such market is not maintained, a Unit
Holder will be able to dispose of its Units through redemption
at prices based on the aggregate bid side evaluation of the
underlying Securities. (See: "Redemption", in Part B.)
Market conditions may cause such prices to be greater or less
than the amount paid for Units.
SPECIAL CONSIDERATIONS -- An investment in Units of
the Trust should be made with an understanding of the risks
which an investment in intermediate term debt obligations may
entail, including the risk that the value of the Units will
decline with increases in interest rates. The Insured
California Trust is considered to be concentrated in General
Revenue Lease Payment Securities (39.74% of the aggregate
market value of the Insured California Trust Portfolio). (See:
"The Trust -- Special Considerations" and "The Trust -- Summary
Description of the Portfolios", in Part B. See also: "Special
Considerations Regarding California Securities", herein, for a
discussion of additional risks relating to Units of such
Trust.)
LADDERED MATURITIES -- The portfolio of the Insured
California Trust was structured as of the Date of Deposit to
return to Unit Holders each year beginning in 1999,
approximately 20% of the per Unit principal amount of the
Securities included in the Trust. (See: "Schedule of
Portfolio Securities".) If interest rates rise, Unit Holders
may be able to reinvest their principal distributions as
received in higher-yielding obligations. Conversely, however,
if interest rates decline, Unit Holders will be receiving
payments of principal at times when only lower-yielding
investments of comparable quality are available. Reinvesting
at such time may result in an over-all lower yield than would
result from a single investment maturing at the close of the
life of the Trust. Such return of 20% of principal each year
may not be achieved due to various factors including the sale
of bonds by the Trust to meet redemptions of Units or for other
permitted reasons, and the bankruptcy of an issuer where the
insurance company insuring the bond does not make the scheduled
principal payment. Consequently, a Unit Holder may receive
less than 20% of the principal amount in one or more years.
PUBLIC DISTRIBUTION -- Sales of Units may be made
pursuant to distribution arrangements with certain banks and/or
other entities subject to regulation by the Office of the
A-6
<PAGE>
Comptroller of the Currency which are acting as agents for
their customers. These banks and/or entities are making Units
of the Trust available to their customers on an agency basis.
A portion of the sales charge paid by these customers is
retained by or remitted to such banks or entities in an amount
equal to the fee customarily received by an agent for acting in
such capacity in connection with the purchase of Units. The
Glass Steagall Act prohibits banks from underwriting certain
securities, including Units of the Trust; however, this Act
does permit certain agency transactions, and banking regulators
have not indicated that these particular agency transactions
are impermissible under this Act. In Texas, as well as certain
other states, any bank making Units available must be
registered as a broker-dealer in that State.
OTHER INFORMATION -- The Securities in the Portfolio
of the Trust were chosen in part on the basis of their
respective maturity dates. An intermediate term Trust contains
obligations maturing in 3 to 10 years from the Date of Deposit.
The maturity date of the Trust is January 1, 2042. The latest
maturity of a Security in the Insured California Trust is
August 2003; and the average life to maturity (or date of pre-
refunding of a bond) of the Portfolio of Securities therein is
3.838 years. The actual maturity dates of each of the
Securities contained in the Insured California Trust are shown
on the "Schedule of Portfolio Securities", herein.
The Trustee shall receive annually 75 cents per
$1,000 principal amount of Securities in the Trust for its
services as Trustee. See: "Expenses and Charges", in Part B,
for a description of other fees and charges which may be
incurred by a Trust.
SALES CHARGE/VOLUME DISCOUNT -- The Public Offering
Price per Unit will be computed by dividing the aggregate of
the bid prices of the Securities in an Insured Trust by the
number of Units outstanding and then adding the appropriate
sales charge described below.
The sales charge will reflect different rates
depending upon the maturities of the various underlying
Securities. The sales charge per Unit in the secondary market
(the "Effective Sales Charge") will be computed by multiplying
the Evaluator's determination of the bid side evaluation of
each Security by a sales charge determined in accordance with
the table set forth below based upon the number of years
remaining to the maturity of each such Security, totalling all
such calculations, and dividing this total by the number of
Units then outstanding. In calculating the date of maturity, a
Security will be considered to mature on its stated maturity
date unless: (a) the Security has been called for redemption
or funds or securities have been placed in escrow to redeem it

on an earlier call date, in which case the call date will be
deemed the date on which such Security matures; or (b) the
Security is subject to a mandatory tender, in which case the
mandatory tender date will be deemed the date on which such
Security matures.

THE INSURED CALIFORNIA TRUST
The Portfolio of the Insured California Trust
consists of seven issues of Securities, all of which were
issued by Issuers located in California. None of the issues of
Securities is a general obligation of an Issuer. All seven
issues of Securities, while not backed by the taxing power of
the Issuer, are payable from revenues or receipts derived from
specific projects or other available sources. The Insured
California Trust contains the following categories of
Securities:
Percentage of Aggregate
Market Value of Trust Portfolio
Category of Security (as of September 8, 1997)
Electric and Power.............. 21.06%
General Revenue Lease Payment... 39.74%
Tax Allocation.................. 18.57%
Water and Sewer................. 18.49%
Prerefunded/Escrowed to
Maturity...................... 2.14%
Original Issue Discount......... 33.36%
See: "The Trust -- Summary Description of the
Portfolios", in Part B, for a summary of the investment risks
associated with the type of Securities contained in the Insured
California Trust. See: "Tax Status", in Part B, for a
discussion of certain tax considerations with regard to
Original Issue Discount.
The range of maturities in the Insured California
Trust is from January 1, 1999 to August 15, 2003. The dollar
weighted average portfolio maturity of the Trust is more than
three years but not more than 10 years.
Of the Original Issue Discount bonds in the Insured
California Trust, approximately 2.81% of the aggregate
principal amount of the Securities in the Insured California
Trust (or 2.14% of the market value of all Securities in the
Insured California Trust on September 8, 1997) are zero coupon
bonds (including bonds known as multiplier bonds, money
multiplier bonds, capital accumulator bonds, compound interest
bonds and discount maturity payment bonds).
The Securities in the Insured California Trust are
insured to maturity by the insurance obtained by the Issuers or
A-10
<PAGE>
by third parties from the following insurance companies:
AMBAC: 27.09%; FGIC: 12.65% and MBIA: 60.26%.a
On September 8, 1997, based on the bid side of the
market, the aggregate market value of the Securities in the
Insured California Trust was $3,582,122.45.
On September 8, 1997, all of the Securities in the
Insured California Trust were rated "AAA" by Standard & Poor's
Corporation because of the Bond Insurance policies issued in
respect of such Securities. (See: the respective "Schedule of
Portfolio Securities", herein, and "Bond Ratings", in Part B.)
A Security in the Portfolio may subsequently cease to be rated
or the rating assigned may be reduced below the minimum
requirements of the Insured California Trust for the
acquisition of Securities. While such events may be considered
by the Sponsor in determining whether to direct the Trustee to
dispose of the Security (see: "Sponsor -- Responsibility", in
Part B), such events do not automatically require the
elimination of such Security from the Portfolio.
SPECIAL CONSIDERATIONS REGARDING CALIFORNIA SECURITIES
Risk Factors
Potential purchasers of the Units of a State Trust
should consider the fact that the Trust's Portfolio consists
primarily of Securities issued by the state for which such
State Trust is named or its municipalities or authorities and
realize the substantial risks associated with an investment in
such Securities. The State Trust is subject to certain
additional risk factors.
The Sponsor believes the information summarized below
describes some of the more significant aspects of the State
Trust. The sources of such information are the official
statements of issuers as well as other publicly available
documents. While the Sponsor has not independently verified
this information, it has no reason to believe that such
information is not correct in all material respects.

<PAGE>
California Trust
The State Trust will be affected by any political,
economic or regulatory developments affecting the ability of
California issuers to pay interest or repay principal on their
obligations. Various developments regarding the California
Constitution and State statutes which limit the taxing and
spending authority of California governmental entities may
impair the ability of California issuers to maintain debt
service on their obligations. The following information
constitutes only a brief summary and is not intended as a
complete description.
In 1978, Proposition 13, an amendment to the
California Constitution, was approved, limiting real property
valuation for property tax purposes and the power of local
governments to increase real property tax revenues and revenues
from other sources. Legislation adopted after Proposition 13
provided for assistance to local governments, including their
distribution of the then-existing surplus in the General Fund,
reallocation of revenues to local governments, and assumption
by the State of certain local government obligations, However,
more recent legislation reduced such state assistance. There
can be no assurance that any particular level of State aid to
local governments will be maintained in future years. In
Nordinger v. Hahn, the United States Supreme Court upheld
certain provisions of Proposition 13 against claims that it
violated the equal protection clause of the Constitution.
In 1979, an amendment was passed adding Article XIIIB
to the State Constitution. As amended in 1990, Article XIIIB
imposes an "appropriations limit" on the spending authority of
the State and local government entities. In general, the
appropriations limit is based on certain 1978-79 expenditures,
adjusted annually to reflect changes in the cost of living,
population and certain services provided by State and local
government entities. The "appropriations limit" does not
include appropriations for qualified capital outlay projects,
certain increases in transportation-related taxes, and certain
emergency appropriations.
If a government entity raises revenues beyond its
"appropriations limit" in any year, a portion of the excess
which cannot be appropriated within the following year's limit
must be returned to the entity's taxpayers within two
subsequent fiscal years, generally by a tax credit, refund or
temporary suspension of tax rates or fee schedules. "Debt
service" is excluded from these limitations, and is defined as
"appropriations required to pay the cost of interest and
redemption charges, including the funding of any reserve or
sinking fund required in connection therewith, on indebtedness
existing or legally authorized as of January 1, 1979 or on
A-12
<PAGE>
bonded indebtedness thereafter approved [by the voters]." In
addition, Article XIIIB requires the State Legislature to
establish a prudent State reserve, and to require the transfer
of 50% of excess revenue to the State School Fund; any amounts
allocated to the State School Fund will increase the
appropriations limit.
In 1986, California voters approved an initiative
statute known as Proposition 62. This initiative (i) requires
that any tax for general governmental purposes imposed by local
governments be approved by resolution or ordinance adopted by a
two-thirds vote of the governmental entity's legislative body
and by a majority vote of the electorate of the governmental
entity, (ii) requires that any special tax (defined as tax
levied for other than general governmental purposes) imposed by
local governmental entity be approved by a two-thirds vote of
the voters within that jurisdiction, (iii) restricts the use of
revenues from a special tax to the purposes or for the service
for which the special tax was imposed, (iv) prohibits the
imposition of ad valorem taxes on real property by local
governmental entities except as permitted by the Proposition 13
amendment, (v) prohibits the imposition of transaction taxes
and sales taxes on the sale of real property by local
governments, (vi) requires that any tax imposed by a local
government on or after August 1, 1985, be ratified by a
majority vote of the electorate within two years of the
adoption of the initiative or be terminated by November 15,
1989, (vii) requires that, in the event a local government
fails to comply with the provisions of this measure, a
reduction of the amount of property tax revenue allocated to
such local government occurs in an amount equal to the revenues
received by such entity attributable to the tax levied in
violation of the initiative, and (viii) permits these
provisions to be amended exclusively by the voters of the State
of California.
In September 1995, the California Supreme court
upheld the constitutionality of Proposition 62, creating
uncertainty as to the legality of certain local taxes enacted
by noncharter cities in California without voter approval. It
is not possible to predict the impact of the decision.
In November 1988, California voters approved
Proposition 98. This initiative requires that revenues in
excess of amounts permitted to be spent and which would
otherwise be returned by revisions of tax rates or fee
schedules, be transferred and allocated (up to a maximum of
40%) to the State School Fund and be expended solely for
purposes of instructional improvement and accountability. No
such transfer or allocation of funds will be required if
certain designated state officials determine that annual
student expenditures and class size meet certain criteria as
A-13
<PAGE>
set forth in Proposition 98. Any funds allocated to the State
School Fund shall cause the appropriation limits to be annually
increased for any such allocation made in the prior year.
Proposition 98 also requires the State of California to provide
a minimum level of funding for public schools and community
colleges. The initiative permits the enactment of legislation,
by a two-thirds vote, to suspend the minimum funding
requirement for one year.
In November 1996, California voters approved
Proposition 218. The initiative applied the provisions of
Proposition 62 to all entities, including charter cities. It
requires that all taxes for general purposes obtain a simple
majority popular vote and that taxes for special purposes
obtain a two-thirds majority vote. Prior to the effectiveness
of Proposition 218, charter cities could levy certain taxes
such as transient occupancy taxes and utility user's taxes
without a popular vote. Proposition 218 will also limit the
authority of local governments to impose property-related
assessments, fees and charges, requiring that such assessments
be limited to the special benefit conferred and prohibiting
their use for general governmental services. Proposition 218
also allows voters to use their initiative power to reduce or
repeal previously-authorized taxes, assessments, fees and
charges.
Certain tax-exempt securities in which the State
Trust may invest may be obligations payable solely from the
revenues of specific institutions, or may be secured by
specific properties, which are subject to provisions of
California law that could adversely affect the holders of such
obligations. For example, the revenues of California health
care institutions may be subject to state laws, and California
law limits the remedies of a creditor secured by a mortgage or
deed of trust on real property.
From 1990 to 1993, California (the "State") faced the
worst economic, fiscal and budget conditions since the 1930s.
Construction, manufacturing (especially aerospace), exports and
financial services, among others, were severely affected. Job
losses were the worst of any post-war recession and have been
estimated to have exceeded 800,000. California's economy has
been recovering and growing steadily stronger since the start
of 1994. The rate of economic growth in California in 1996, in
terms of job gains, exceeded that of the rest of the United
States. The State added nearly 350,000 jobs during 1996,
surpassing its pre-recession employment peak of 12.7 million
jobs. Another 380,000 jobs are expected to be created in 1997.
The unemployment rate, while still higher than the national
average, fell to the low 6 percent range in mid-1997, compared
to over 10 percent during the recession. Many of the new jobs
were created in such industries as computer services, software
A-14
<PAGE>
design, motion pictures and high technology manufacturing.
Business services, export trade and other manufacturing also
experienced growth. All major economic regions of the State
grew, with particularly large gains in the Silicon Valley
region of Northern California. Personal income grew by over 7
percent or $55 billion in 1996. The residential construction
sector of the State's economy remained weak in 1996, with
permits for new housing increasing modestly from the previous
year. In addition, the restructuring and consolidation
occurring in California's aerospace and financial services
industries, while aimed at making the companies involved more
efficient and competitive in the longer term, has produced some
negative economic consequences in the shorter term, including
an uncertain job outlook for many workers.
The recession affected State tax revenues, which
mirror economic conditions. It has also caused increased
expenditures for health and welfare programs. The State has
also been facing a structural imbalance in its budget with the
largest programs supported by the General Fund (K-12 schools
and community colleges, health, welfare and corrections)
growing at rates higher than the growth rates for the principal
revenue sources of the General Fund. (The General Fund, the
State's main operating fund, consists of revenues which are not
required to be credited to any other fund.) As a result, the
State experienced recurring budget deficits. With the end of
the recession, the State's financial condition has improved in
the 1995-96 and 1996-97 fiscal years, with a combination of
better than expected revenues, slowdown in growth of social
welfare programs, and continued spending restraint. As of
June 30, 1997, the State's budget reserve had a positive cash
balance of $281 million. No deficit borrowing has occurred at
the end of the last two fiscal years and the State's cash flow
borrowing was limited to $3 billion in 1996-97.
On December 6, 1994, Orange County, California (the
"County"), together with its pooled investment funds (the
"Pools"), filed for protection under Chapter 9 of the federal
Bankruptcy Code. On June 12, 1996, Orange County emerged from
bankruptcy after the successful sale of $880 million in
municipal bonds allowed the county to pay off the last of its
creditors. On January 7, 1997, Orange County returned to the
municipal bond market with a $136 million bond issue maturing
in 13 years at an insured yield of 7.23 percent.
Los Angeles County, the nation's largest county is
also experiencing financial difficulty. In August 1995 the
credit rating of the County's long-term bonds was downgraded
for the third time since 1992 as a result of, among other
things, severe operating deficits for the County's health care
system. In addition, the County was affected by an ongoing
loss of revenue caused by state property tax shift initiatives
A-15
<PAGE>
in 1993 through 1995. In June, 1997, the Los Angeles County
Board of Supervisors approved an approximately $12 billion
1997-98 budget containing measures to eliminate a $157 million
deficit. The County's budgetary difficulties have continued
and their effect, as well as the effect of the improving
California economy, on the 1997-1998 budget is still uncertain.
1997-98 Fiscal Year Budget
On August 18, 1997, the Governor signed the 1997-98
Budget Act. The Budget Act anticipates General Fund revenues
and transfers of $52.5 billion (a 6.8 percent increase over the
final 1996-97 levels), and expenditures of $52.8 billion (an
8.0 percent increase from the 1996-97 levels). On a budgetary
basis, the budget reserve (SFEU) is projected to decrease from
$408 million at June 30, 1997 to $112 million at June 30, 1998.
(The expenditure figure assumes restoration of $200 million of
vetoed funding.) The Budget Act also includes Special Fund
expenditures of $14.4 billion (as against estimated Special
Fund revenues of $14.0 billion), and $2.1 billion of
expenditures from various Bond Funds. Following enactment of
the Budget Act, the State implemented its annual cash flow
borrowing program, issuing $3 billion of notes which mature on
June 30, 1998.
The following are major features of the 1997-98
Budget Act:
1. For the second year in a row, the Budget
contains a large increase in funding for K-14 education,
reflecting strong revenues which have exceeded initial budgeted
amounts. Part of the nearly $1.75 billion in increased
spending is allocated to prior fiscal years.
2. The Budget Act reflects a $1.235 billion pension
case judgment payment, and returns funding of the State's
pension contribution to the quarterly basis existing prior to
the deferral actions invalidated by the courts. In May, 1997,
the California Supreme Court in PERS v. Wilson made final a
judgment against the State requiring an immediate payment from
the General Fund to the Public Employees Retirement Fund
("PERF") to make up certain deferrals in annual retirement fund
contributions which had been legislated in earlier years for
budget savings, and which the courts found to be
unconstitutional. On July 30, 1997, at the Governor's
direction, the Controller transferred $1.235 billion from the
General Fund to the PERF in satisfaction of the judgment,
representing the principal amount of the improperly deferred
payments from 1995-96 and 1996-97. No provision exists for any
additional payments relating to this court case.
A-16
<PAGE>
3. Continuing the third year of a four-year
"compact" which the State Administration has made with higher
education units, funding from the General Fund for the
University of California and California State University has
increased by about 6 percent ($121 million and $107 million,
respectively), and there was no increase in student fees.
4. Because of the effect of the pension payment,
most other State programs were continued at 1996-97 levels.
5. Health and welfare costs are contained,
continuing generally the grant levels from prior years, as part
of the initial implementation of the new CalWORKs welfare
reform program.
6. Unlike prior years, this Budget Act does not
depend on uncertain federal budget actions. About $300 million
in federal funds, already included in the federal FY 1997 and
1998 budgets, are included in the Budget Act, to offset
incarceration costs for illegal immigrants.
7. The Budget Act contains no tax increases, and no
tax reductions. The Renters Tax Credit was suspended for
another year, saving approximately $500 million.
Subsequent to the adoption and signature of the
Budget Act, the Governor and Legislature reached certain
agreements related to State expenditures and taxes, including
support, on an annual basis, for a $931 million (by full
implementation in the 1999-2000 fiscal year) tax cut aimed
primarily at middle income families but also including
businesses, $480 million to provide health insurance for
uninsured children, $450 million to pay for county courts, $300
million for pay raises for state employees, and $52 million for
tuition cuts for California public universities and community
colleges. These agreements mostly will affect budgets in
future fiscal years and their impact on the State's budget and
the State's support for local governments is uncertain.
THE FOREGOING DISCUSSION OF THE 1997-98 FISCAL YEAR
BUDGET IS BASED IN LARGE PART ON STATEMENTS MADE IN A RECENT
"PRELIMINARY OFFICIAL STATEMENT" DISTRIBUTED BY THE STATE OF
CALIFORNIA. IN THAT DOCUMENT, THE STATE INDICATED THAT ITS
DISCUSSION OF THE FISCAL YEAR BUDGET IS BASED ON ESTIMATES AND
PROJECTIONS OF REVENUES AND EXPENDITURES FOR THE CURRENT FISCAL
YEAR AND MUST NOT BE CONSTRUED AS STATEMENTS OF FACT. THE
STATE NOTED FURTHER THAT THE ESTIMATES AND PROJECTIONS ARE
BASED UPON VARIOUS ASSUMPTIONS WHICH MAY BE AFFECTED BY
NUMEROUS FACTORS, INCLUDING FUTURE ECONOMIC CONDITIONS IN THE
STATE AND THE NATION, AND THAT THERE CAN BE NO ASSURANCE THAT
THE ESTIMATES WILL BE ACHIEVED.
A-17
<PAGE>
State Indebtedness
As of August 1, 1997, the State had over $17.82
billion aggregate amount of its general obligation bonds
outstanding. General obligation bond authorizations in an
aggregate amount of approximately $8.26 billion remained
unissued as of August 1, 1997. The State also builds and
acquires capital facilities through the use of lease purchase
borrowing. As of August 1, 1997, the State had approximately
$6.17 billion of outstanding Lease-Purchase Debt.
In addition to the general obligation bonds, State
agencies and authorities had approximately $19.09 billion
aggregate principal amount of revenue bonds and notes
outstanding as of June 30, 1997. Revenue bonds represent both
obligations payable from State revenue-producing enterprises
and projects, which are not payable from the General Fund, and
conduit obligations payable only from revenues paid by private
users of facilities financed by such revenue bonds. Such
enterprises and projects include transportation projects,
various public works and exposition projects, educational
facilities (including the California State University and
University of California systems), housing, health facilities
and pollution control facilities.
Litigation
The State is a party to numerous legal proceedings,
many of which normally occur in governmental operations. In
addition, the State is involved in certain other legal
proceedings that, if decided against the State, might require
the State to make significant future expenditures or impair
future revenue sources.
Ratings
Because of the State's continuing budget problems,
the State's General Obligation bonds were downgraded in July
1994 to A1 from Aa by Moody's, to A from A+ by Standard &
Poor's, and to A from AA by Fitch. All three rating agencies
expressed uncertainty in the State's ability to balance the
budget by 1996. However, in 1996, citing California's
improving economy and budget situation, both Fitch and Standard
& Poor's raised their ratings from A to A+.
The Sponsor believes the information summarized above
describes some of the more significant aspects relating to the
California Trust. The sources of such information are
Preliminary Official Statements and Official Statements
relating to the State's general obligation bonds and the
State's revenue anticipation notes, or obligations of other
issuers located in the State of California, or other publicly
A-18
<PAGE>
available documents. Although the Sponsor has not
independently verified this information, it has no reason to
believe that such information is not correct in all material
respects.
California Tax Status
On the Date of Deposit, special California counsel
for the Sponsor rendered an opinion under the then existing
California state income tax law which read as follows:
The Insured California Trust is not an association
taxable as a corporation under the income tax laws of the
State of California;
The income, deductions and credits against tax of the
Insured California Trust will be treated as the income,
deductions and credits against tax of the holders of Units
in the Insured California Trust under the income tax laws
of the State of California;
Interest on the bonds held by the Insured California
Trust to the extent that such interest is exempt from
taxation under California law will not lose its character
as tax-exempt income merely because that income is passed
through to the holders of Units; however, a corporation
subject to the California franchise tax is required to
include that interest income in its gross income for
purposes of determining its franchise tax liability;
Each holder of a Unit in the Insured California Trust
will have a taxable event when the Insured California
Trust disposes of a bond (whether by sale, exchange,
redemption, or payment at maturity) or when the Unit
holder redeems or sells his Units. The total tax cost of
each Unit to a holder of a Unit in the Insured California
Trust is allocated among each of the bond issues held in
the Insured California Trust (in accordance with the
proportion of the Insured California Trust comprised by
each bond issue) in order to determine the holder's per
Unit tax cost for each bond issue, and the tax cost
reduction requirements relating to amortization of bond
premium will apply separately to the per Unit tax cost of
each bond issue. Therefore, under some circumstances, a
holder of a Unit may realize taxable gain when the Insured
California Trust disposes of a bond or the holder's Units
are sold or redeemed for an amount equal to or less than
his original cost of the bond or Unit;
Each holder of a Unit in the Insured California Trust
is deemed to be the owner of a pro rata portion of the
A-19
<PAGE>
Insured California Trust under the personal property tax
laws of the State of California;
Each Unit holder's pro rata ownership of the bonds
held by the Insured California Trust, as well as the
interest income therefrom, is exempt from California
personal property taxes; and
Amounts paid in lieu of interest on defaulted bonds
held by the Trustee under policies of insurance issued
with respect to such bonds will be excludable from gross
income for California income tax purposes if, and to the
same extent as, those amounts would have been so
excludable if paid as interest by the respective issuer.
In the opinion of Messrs. Paul, Hastings, Janofsky &
Walker LLP, special California counsel to the Sponsor, no
change in law has occurred since the Date of Deposit which
would require a change in the above opinion.

The Trust is registered under the Investment Company Act of 1940 as a

(1) Basis of Presentation
The Trustee has custody of and responsibility for all accounting and
financial books, records, financial statements and related data of
the Trust and is responsible for establishing and maintaining a
system of internal controls directly related to, and designed to
provide reasonable assurance as to the integrity and reliability
of, financial reporting of the Trust. The Trustee is also
responsible for all estimates and accruals reflected in the Trust's
financial statements. The Evaluator determines the price for each
underlying Security included in the Trust's Portfolio of Securities
on the basis set forth in Part B of this Prospectus, "Public
Offering of Units - Public Offering Price". Under the Securities
Act of 1933 ("the Act"), as amended, the Sponsor is deemed to be an
issuer of the Trust Units. As such, the Sponsor has the
responsibility of an issuer under the Act with respect to financial
statements of the Trust included in the Trust's Registration
Statement under the Act and amendments thereto.
(2) Investments
Investments are stated at market value as determined by the
Evaluator based on the bid side evaluations on the last day of
trading during the period, except that value on the date of deposit
(August 26, 1993) represents the cost of investments to the Trust
based on the offering side evaluations as of the day prior to the
date of deposit.
(3) Income Taxes
The Trust is not an association taxable as a corporation for Federal
income tax purposes; accordingly, no provision is required for such
taxes.
(4) Expenses
The Trust pays annual Trustee's fees, estimated expenses,
Evaluator's fees, and annual Sponsor's portfolio supervision fees
and may incur additional charges as explained under "Expenses and
Charges - Fees" and "- Other Charges" in Part B of this Prospectus.

Re: Dean Witter Select Municipal Trust,
Insured California Intermediate Term
Portfolio Series 10
Gentlemen:
It is our understanding that you are filing with the
Securities and Exchange Commission a Post-Effective Amendment
to the captioned Trust, SEC file number 33-49707.
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 ratings by Standard &
Poor's, we reaffirm the assignment of a "AAA" rating to the
units of the trust and a "AAA" rating to the securities
contained in the trust.
You have permission to use the name of Standard &
Poor's Ratings Services, a division of The McGraw-Hill
Companies, Inc. and the above-assigned ratings in connection
with your dissemination of information relating to these units,
provided that it is understood that the ratings are not
"market" ratings nor recommendations to buy, hold, or sell the
units of the trust or the securities in the trust. Further, it
should be understood that the rating on the units does not take
into account the extent to which fund expenses or portfolio
asset sales for less than the fund's purchase price will reduce
payment to the unit holders of the interest and principal
required to be paid on the portfolio assets. Standard & Poor's
reserves the right to advise its own clients, subscribers, and
the public of the ratings. Standard & Poor's relies on the
sponsor and its counsel, accountants, and other experts for the
<PAGE>
-2-
accuracy and completeness of the information submitted in
connection with the ratings. Standard & Poor's does not
independently verify the truth or accuracy of any such
information.
This letter evidences our consent to the use of the
name of Standard & Poor's Ratings Services, a division of The
McGraw-Hill Companies, Inc. in connection with the rating
assigned to the units in the 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 & Poor's Ratings
Services, a division of The McGraw-Hill Companies, Inc. in
connection with the ratings assigned to the securities
contained in the trust. You are hereby authorized to file a
copy of this letter with the Securities and Exchange
Commission.
Please be certain to send a copy of your final
prospectus as soon as it becomes available. Should we not
receive it within a reasonable time after the closing or should
it not conform to the representations made to us, we reserve
the right to withdraw the rating.
We are pleased to have had the opportunity to be of
service to you. If we can be of further help, please do not
hesitate to call upon us.
Sincerely
Sanford B. Bragg
