INVESTMENT SUMMARY

INVESTMENT OBJECTIVE. The Industrial Trust Series IV (the "Industrial Trust")
and the Technology Trust Series IV (the "Technology Trust") each seek to
maximize total return through capital appreciation. There is no guarantee that
the investment objectives of the Trusts will be achieved.

STRATEGY OF PORTFOLIO SELECTION.

The Industrial Trust. The Industrial Trust seeks to achieve its investment
objective by investing in a fixed portfolio of the 25 best performing stocks on
the S&P 500 Index*, as measured by price appreciation, during the twelve-month
period ending December 31, 1999. Price appreciation is measured by the
percentage change in market value of each stock from December 31, 1998 through
December 31, 1999. This strategy involves a 4-step selection process:

Step 1: Calculate the price appreciation for each company listed on the S&P
500 Index over the 12-month period ending December 31, 1999.

Step 2: Eliminate non-ordinary common shares (including preferred
securities, rights and warrants) and foreign issues (except
American Depository Receipts).

Step 3: Select the 25 stocks which have the greatest price appreciation.

Step 4: Of the 25 stocks selected for the Trust, weigh the stocks equally.

The Technology Trust. The Technology Trust seeks to achieve its investment
objective by investing in a fixed portfolio of stocks, comprised primarily of
technology companies which had both high trading volume and price appreciation,
during the twelve-month period ending December 31, 1999. Trading volume is
measured using data from Standard & Poor's Institutional Market Services,
Englewood, Colorado. Price appreciation is measured by the percentage change in
market value of each stock from December 31, 1998 through December 31, 1999.
Technology stocks are identified as those companies that derive the majority of
their revenue from the technology industry, using data from Standard & Poor's
Institutional Market Services, Englewood, Colorado. This strategy also involves
a 4-step selection process:

Step 1: Calculate the number of shares traded daily, for each company
listed on the NASDAQ* and the NYSE*, on each day the NASDAQ and the
NYSE were open over the twelve-month period ending December 31,
1999.

Step 2: Eliminate non-ordinary common shares (including preferred
securities, rights and warrants) and foreign issues (except
American Depository Receipts).

- --------
* The Standard & Poor's 500 Index (S&P), The National Association of
Securities Dealers Automated Quotations System (NASDAQ) and The New York
Stock Exchange (NYSE) are not affiliated with the Sponsors and have not
participated in any way in the creation of the Trusts or in the selection
of the stocks included in the Trusts and have not reviewed or approved any
information included in this Prospectus.

A-2
<PAGE>

Step 3: Identify: (i) the 12 stocks that had the highest number of shares
traded on the NASDAQ during the twelve-month period ending December
31, 1999 and from those 12 stocks select the stocks that had price
appreciation of 40% or greater during the same period; and (ii) the
40 stocks listed on the NYSE which had the highest number of shares
traded during the twelve-month period ending December 31, 1999 and
select the technology stocks which had price appreciation of 40% or
greater during the same period.

Step 4: Of the 14 stocks selected for the Trust, weigh the stocks in the
following manner:

12% in each of the first two companies to rank in the top half of the
volume and price categories, first by volume and then by price;

7% in each of the four companies that ranked highest in the trading
volume category and 7% in each of the four companies that ranked
highest in the price appreciation category, excluding any company
that was already selected and received a 12% weighting; and

5% in each of the remaining companies.

The volume of shares traded daily on the NASDAQ (and NYSE) does not include
shares represented by options trading. The inclusion of shares represented by
options may have provided different results and therefore the selection of
stocks for inclusion in the Technology Trust may have differed.

DESCRIPTION OF TRUSTS.

The Industrial Trust. The Industrial Trust contains 25 issues of common stock.
All 25 issues are domestic companies. 100% of the issues are represented by the
Sponsors' contracts to purchase. 11 of the stocks are listed on the NYSE and 14
of the stocks are listed on the NASDAQ. Based upon the principal business of
each issuer and current market values, the following industries are represented
in the Trust: Cellular-Wireless Telecommunications, 8.02%; Communication--
Equipment, 12.02%; Computers--Hardware, 12.04%; Computers--Networking, 8.00%;
Computers--Peripherals, 3.99%; Computers--Software/Services, 15.94%;
Electrical--Instruments, 3.98%; Electronics--Semiconductors, 19.96%;
Equipment--Semiconductors, 12.08%; and Manufacturing--Diversified, 3.97%. The
Trust is concentrated in the computer industry.

The Technology Trust. The Technology Trust contains 14 issues of common stock.
All 14 issues are domestic companies. 100% of the issues are represented by the
Sponsors' contracts to purchase. 8 of the stocks are listed on the NASDAQ and
the remaining 6 are listed on the NYSE. Based upon the principal business of
each issuer and current market values, the following industries are represented
in the Trust: Communications Equipment, 7.01%; Computers--Hardware, 11.98%;
Computers--Networking, 12.00%; Computers--Peripherals, 6.98%; Computers--
Software/Services, 33.04%; Electronics--Semiconductors, 10.04%; Equipment--
Semiconductors, 6.96%; Investment Banking/Brokerage, 5.01%; and Retail-Home
Shopping, 6.98%. The Trust is concentrated in the computer technology industry.

A Trust is considered to be "concentrated" in a particular category or industry
when the securities in that category or that industry constitute 25% or more of
the total assets of the portfolio.

A-3
<PAGE>

RISK CONSIDERATIONS. Unitholders can lose money by investing in the Trusts. The
value of the Units and the Securities in the Trusts can each decline in value.
An investment in Units of the Trusts should be made with an understanding of
the following risks:

Risk Factors Common to Both Trusts:

. An investment in common stocks includes the risk that the financial
condition of the issuers of the Securities may become impaired or that
the general condition of the stock market may worsen (both of which may
contribute directly to a decrease in the value of the Securities and thus
in the value of the Units).

. Since the portfolios of the Trusts are fixed and "not managed," in
general, the Sponsors can sell Securities only at the Trusts' termination
or in order to meet redemptions. As a result, the price at which each
Security is sold may not be the highest price it attained during the life
of the Trusts.

. When cash or a letter of credit is deposited with instructions to
purchase securities in order to create additional Units, an increase in
the price of a particular security between the time of deposit and the
time that securities are purchased will cause the Units to be comprised
of less of that security and more of the remaining securities. In
addition, brokerage fees incurred in purchasing the Securities will be an
expense of the Trusts.

. Securities price fluctuations during the period from the time of deposit
to the time the Securities are purchased, and payment of brokerage fees,
will affect the value of each Unit and the income per Unit received by
the Trusts.

. Investors should also consider the greater risk of a Trust's
concentration, in a particular industry or in a single stock, and the
effect on their investment versus a more diversified portfolio. Investors
should compare returns available in less concentrated portfolios before
making an investment decision.

. Some of the Securities are currently listed on the NASDAQ stock market.
The existence of a liquid trading market for certain Securities may
depend on whether dealers will make a market in such Securities. There
can be no assurance that a market will be made for any of the Securities,
that any market for the Securities will be maintained or that any such
market will be or remain liquid. The price at which the Securities may be
sold and the value of the Trusts will be adversely affected if trading
markets for the securities are limited or absent.

. Since the Trusts are concentrated in stocks which derive a substantial
portion of their income from the computer and computer technology
industries, investors should be familiar with the risks associated with
these industries which may include the volatile price of computer and
technology stocks, greater government regulations and products that may
become obsolete.

PUBLIC OFFERING PRICE. The Initial Public Offering Price per 100 units of the
Trusts is calculated by:

. dividing the aggregate value of the underlying securities and cash held
in the Trusts (representing the estimated organizational costs) by the
number of units outstanding;

. adding a sales charge of 4.495% (4.707% of the net amount invested) for
the Industrial and Technology Trusts; and

A-4
<PAGE>

. multiplying the result by 100.

In addition, during the initial offering period, the Public Offering Price per
100 units will include an amount sufficient to reimburse the Sponsors for the
payment of all or a portion of the estimated organizational costs of the
Trusts. The price of a single unit, or any multiple thereof, is calculated by
dividing the Public Offering Price per 100 units by 100 and multiplying by the
number of units. The Public Offering Price per Unit will vary on a daily basis
in accordance with fluctuations in the aggregate value of the underlying
Securities and each investor's purchase price will be computed as of the date
the Units are purchased. Orders involving at least 25,000 Units will be
entitled to a volume discount from the Public Offering Price.

MINIMUM PURCHASE. 100 Units for individuals and 25 Units for custodial accounts
and certain tax deferred retirement plans.

DISTRIBUTIONS. Each Trust will distribute any dividends received, less
expenses, semi-annually. The Trusts do not expect to distribute dividends,
however, in the event any dividend distributions are made, the first dividend
distribution will be made on June 30, 2000 to all Unitholders of record on June
15, 2000 and thereafter distributions will be made on the last business day of
every December and June. The final distribution will be made within a
reasonable period of time after each Trust terminates.

MARKET FOR UNITS. Unitholders may sell their Units to the Sponsors or the
Trustee at any time, without fee or penalty. The Sponsors intend to repurchase
Units from Unitholders throughout the life of the Trusts at prices based upon
the market value of the underlying Securities. However, the Sponsors are not
obligated to maintain a market and may stop doing so without prior notice for
any business reason. If a market is not maintained, a Unitholder will be able
to redeem his Units with the Trustee at the same price. The existence of a
liquid trading market for the Securities in each of the Trusts may depend on
whether dealers will make a market in these Securities. There can be no
assurance of the making or the maintenance of a market for any of the
Securities contained in the portfolio of the Trusts or of the liquidity of the
Securities in any markets made. The price at which the Securities may be sold
to meet redemptions and the value of the Units will be adversely affected if
trading markets for the Securities are limited or absent.

AUTOMATIC REDEMPTION. Any transfer of Units by Unitholders from their
McLaughlin, Piven, Vogel brokerage account will result in the automatic
redemption of those Units. Unitholders, excluding tax sheltered retirement
accounts, will generally incur a taxable gain or loss upon an involuntary
redemption. See "Tax Status" in Part B.

TERMINATION. Each Trust will terminate in approximately fifteen months. During
the Liquidation Period, Securities will be sold in connection with the
termination of each Trust. All Securities will be sold or distributed by the
Mandatory Termination Date. The Sponsors do not anticipate that the Liquidation
Period will be longer than seven days, and it could be as short as one day,
depending on the liquidity of the Securities being sold. Unitholders may elect
one of the following three options in receiving their terminating
distributions:

. receive their distribution in-kind, if they own at least 2,500 Units;

. receive cash upon the liquidation of their pro rata share of the
Securities; or

. reinvest in a subsequent series of The Pinnacle Family of Trusts
(formerly known as the McLaughlin, Piven, Vogel Family of Trusts) (if one
is offered), at a reduced sales charge.

A-5
<PAGE>

ROLLOVER OPTION. Unitholders may elect to rollover their terminating
distributions into the next available series of The Pinnacle Family of Trusts,
at a reduced sales charge. Rollover Unitholders must make this election on or
prior to the Rollover Notification Date. When Unitholders make this election,
their Units will be redeemed and the proceeds will be reinvested in units of
the next available series of The Pinnacle Family of Trusts. An election to
rollover terminating distributions will generally be a taxable event. See
"Administration of the Trusts--Trust Termination" in Part B for details to make
this election.

REINVESTMENT PLAN. Unitholders may elect to automatically reinvest any
distributions they may receive (except the final distribution made at
termination) into additional Units of the Trusts at a reduced sales charge of
1.00%. See "Reinvestment Plan" in Part B for details on how to enroll in the
Reinvestment Plan.

UNDERWRITING. McLaughlin, Piven, Vogel Securities, Inc., with principal offices
at 30 Wall Street, New York, New York 10005, will act as Underwriter for all of
the Units of The Pinnacle Family of Trusts, Industrial Trust Series IV and
Technology Trust Series IV.

This Fee Table is intended to help you understand the costs and expenses you
will bear directly or indirectly. See "Public Sale of Units" and "Trust
Expenses and Charges" in Part B. Although the Trusts each have a term of only
approximately fifteen months and are unit investment trusts rather than mutual
funds, this information is presented to permit a comparison of fees, assuming
the principal amount and distributions are rolled over each year into a new
series subject only to a sales charge and trust expenses.

Example

This Example is intended to help you compare the cost of investing in the
Trusts with the cost of investing in other unit trusts. You would pay the
following expenses on a $10,000 investment in each Trust assuming estimated
operating expense ratio of .155% for the Industrial Trust and .155% for the
Technology Trust, and a 5% return on the investment throughout the period.
Although your actual costs may be higher or lower, based on these assumptions
your costs would be:
<TABLE>
<CAPTION>
1 year 3 years
------ -------
<S> <C> <C>
Industrial Trust................................................. $544 $1,527
Technology Trust................................................. $544 $1,527
</TABLE>

For purposes of the example, the sales charge imposed on reinvested dividends
is not reflected until the year following payment of the dividend; the
cumulative expenses would be higher if sales charges on reinvested dividends
were reflected in the year of reinvestment. If these charges and fees were
included, your costs would be higher. The Example assumes reinvestment of all
dividends and distributions and utilizes a 5% annual rate of return as mandated
by Securities and Exchange Commission regulations applicable to mutual funds.
The Example should not be considered a representation of past or future
expenses or an annual rate of return.

The Annual Maintenance Fee is applicable to your entire brokerage account
regardless of account size or diversity of holdings and is not related solely
to the purchase of Units. Such account may entitle Unitholders to a commission
discount for equity trades. Contact your account representative for additional
information and see "Public Sale of Units" in Part B.

Notes to Statements of Financial Condition:

The preparation of financial statements in accordance with generally accepted
accounting principles requires Trust management to make estimates and
assumptions that affect the reported amounts and disclosures. Actual results
can differ from those estimates.

(1) The Pinnacle Family of Trusts, Industrial Trust Series IV and Technology
Trust Series IV (the "Trusts") are unit investment trusts created under the
laws of the State of New York and registered under the Investment Company Act
of 1940. The objective of the Industrial and Technology Trusts, jointly
sponsored by McLaughlin, Piven, Vogel Securities, Inc. and Reich & Tang
Distributors, Inc., the Sponsors, is to maximize total return through capital
appreciation. An irrevocable letter of credit issued by BankBoston in an amount
of $400,000 has been deposited with the Trustee for the benefit of the Trusts
to cover the purchases of such Securities. Aggregate cost to the Trusts of the
Securities listed in the portfolios is determined by the Trustee on the basis
set forth under "Public Sale of Units--Public Offering Price" as of 4:00 p.m.
on January 18, 2000. Each Trust will terminate on April 17, 2001 or earlier
under certain circumstances as further described in the Prospectus.

(2) A portion of the Public Offering Price consists of cash in an amount
sufficient to reimburse the Sponsors for the per Unit portion of all or part of
the costs of establishing the Trusts. These costs have been estimated at $1.12
per 100 Units for the Industrial Trust and $1.12 per 100 Units for the
Technology Trust. A payment will be made as of the close of the initial public
offering period to an account maintained by the Trustee from which the
obligation of the investors to the Sponsors will be satisfied. To the extent
that actual organization costs are less than the estimated amount, only the
actual organization costs will be deducted from the assets of the Trusts.

THE PINNACLE FAMILY OF TRUSTS

INDUSTRIAL TRUST SERIES IV
A Core Growth Portfolio

Everyday, investors pour money into the stock market to reach a variety of
individual goals: to fund retirement, a college education, a new home or even a
dream vacation. But when it comes to your goals, it is important that you have
a carefully planned strategy in place--one that aims to make the most of
opportunities in today's leading businesses. A core holding in some of the
foremost largely capitalized companies in the United States may be a good place
to begin constructing a portfolio to help you achieve your own unique financial
objectives.

The Industrial Trust Series IV is a new unit investment trust for individuals
who want the opportunity to earn capital appreciation from a portfolio of the
twenty-five top performing stocks in the S&P 500 Index.* In particular, these
stocks have been noted for their rate of price appreciation for the twelve-
month period that ended December 31, 1999.

The Grand Advantage

In today's volatile markets, larger, more established companies may add
stability to your portfolio. Domestic companies with solid track records may
weather global volatility better than their smaller counterparts. And while
past performance does not guarantee future results, large-cap stocks have a
history of significant appreciation that makes them competitive with riskier
small and mid-cap stocks.

The S&P 500--A Measure of Performance

When it comes to measuring the movements of the U.S. stock market, one of the
most widely used tools is the Standard & Poor's 500 Composite Stock Price
Index--The S&P 500. In fact, approximately 97% of U.S. money managers and
pension plan sponsors use the index as their benchmark for performance.** The
Index focuses on the stocks of large-capitalization, U.S. companies in leading
industries, including the transportation, industrial, financial and utility
sectors.

The 500 stocks in the index are chosen by Standard & Poor's based on how well
they represent their industry, how liquid each individual stock is, and how
stable the company has proven to be over time. While the S&P 500 may not
comprise the 500 largest companies in the stock market, it is an index designed
to capture the returns of many different sectors of the U.S. economy.

HIGHLIGHTS OF THE INDUSTRIAL TRUST SERIES IV

Disciplined Investing--The buy-and-hold, fixed portfolio eliminates
management fees and reduces trading expenses. The savings are passed through to
investors. Investors purchasing units will be charged a sales charge.

<PAGE>

Monitored Portfolio--The stocks held in your portfolio are continuously
monitored, and under certain, limited, extraordinary circumstances, can be
removed from the portfolio.

Daily Pricing & Liquidity--You have the flexibility to redeem your units at
the net asset value any day the stock market is open. Keep in mind that the
daily price will fluctuate with the underlying securities, and may be worth
more or less than you originally paid.

Low Minimum Investment--The Trust is able to offer the twenty-five top
performing stocks in the S&P 500 Index, as measured by price appreciation, for
the twelve-month period that ended December 31, 1999 for an initial investment
that's as low as $1,000 or $250 for qualified retirement plans or custodial
accounts.

Compounded Returns--You have the option to take advantage of the power of
compounding by having distributions, if any, automatically reinvested into
additional units of the Trust at a reduced sales charge.

Three Options at Termination--The portfolio is held for approximately 15
months and then liquidated. When the Trust terminates you have three options,
which may be subject to tax liability. You may:

1. Receive your distribution in cash,
2. Reinvest your proceeds into a new trust (if available) at a reduced
sales charge, or
3. Receive the shares of the underlying stocks (minimums apply).

Risk Considerations:

An investment in Units of the Trust should be made with an understanding of
the risks associated with an investment in common stocks, which include the
risks that the financial condition of the issuer may become impaired or that
the general condition of the stock market may worsen, and the value of the
equity securities in the Trust's portfolio (and, therefore, the value of the
Units) may decline. In addition, the amount realized upon the sale of a
security at termination might not be the highest price attained by an
individual security during the life of the Trust.

TECHNOLOGY TRUST SERIES IV
Capitalizing on Today's Premier Growth Sector

The Technology Trust Series IV is a unique opportunity for individuals who
want to invest in one of today's premier growth sectors. The Technology Trust
Series IV is a unit investment trust that seeks capital appreciation by
investing in a portfolio of many of the leading technology companies that
currently trade on the NASDAQ and NYSE*. And, what makes the Trust distinct is
it invests primarily in dominant technology companies that have already
demonstrated that they're helping to fuel the modern economy.

The Technology Trust Series IV offers high return potential by investing
mainly in a portfolio of the fastest growing technology stocks that trade on
the NASDAQ and NYSE. The Trust, which is a fixed portfolio of stocks, is
selected by focusing on the most actively traded companies listed on the two
exchanges. From this universe of stocks, the companies with a 40% or more price
appreciation are chosen for the Trust. The selection of the portfolio is based
on data compiled over the 12-month period ending December 31, 1999.

(NASDAQ) and the New York Stock Exchange (NYSE) are not affiliated with the

Why a Technology Portfolio?

Technology is an industry that helped shape not only the last few years, but
will also help shape the new millennium. It is providing innovative solutions
that help businesses improve everything from customer service to production,
which ultimately enhances the bottom line. However, technology isn't just part
of the business world. In our personal lives we encounter new technology every
day. Email, cellular phones, the Internet, and the infinite uses for
microprocessors have changed the way we relax, and even keep in touch with one
another.

Such potential is why many experts agree that despite periods of short-term
volatility, technology may be a core long-term growth sector that can benefit
most portfolios. An investment designed to tap into the power of this
burgeoning area provides the potential for superior capital appreciation.

HIGHLIGHTS OF THE TECHNOLOGY TRUST SERIES IV

Monitored Portfolio--The stocks held in your portfolio are continuously
monitored, and under certain, limited, extraordinary circumstances, can be
removed from the portfolio.

Low Minimum Investment--The Trust is able to offer this portfolio comprised
primarily of technology stocks for an initial investment that's as low as
$1,000 or $250 for qualified retirement plans or custodial accounts.

Three Options at Termination--The portfolio is held for approximately 15
months and then liquidated. When the Trust terminates, you have three options,
which may be subject to tax liability. You may:

1. Receive your distribution in cash,
2. Reinvest your proceeds into a new trust (if available) at a reduced
sales charge, or
3. Receive the shares of the underlying stocks (minimums apply).

Risk Considerations:

An investment in Units of the Trust should be made with an understanding of
the risks associated with an investment in common stocks, which include the
risks that the financial condition of the issuer may become impaired or that
the general condition of the stock market may worsen, and the value of the
equity securities in the Trust's portfolio (and, therefore, the value of the
Units) may decline. Since the Trust may be concentrated in computer technology
stocks, investors should recognize the risks associated with the computer
technology industry, which may include government regulation and obsolete
products. In addition, the amount realized upon the sale of a security at
termination might not be the highest price attained by an individual security
during the life of the Trust.

INDUSTRIAL TRUST SERIES IV
(the "Industrial Trust")

TECHNOLOGY TRUST SERIES IV
(the "Technology Trust")

PROSPECTUS--PART B

PART B OF THIS PROSPECTUS MAY NOT BE
DISTRIBUTED UNLESS ACCOMPANIED BY
PART A

THE TRUSTS

ORGANIZATION. Each of the Trusts were created under New York State law
pursuant to an Indenture and Trust Agreement ("Trust Agreement") among
McLaughlin, Piven, Vogel Securities, Inc. and Reich & Tang Distributors, Inc.,
as Sponsors, and The Chase Manhattan Bank, as Trustee.

On the Initial Date of Deposit, (i) the Sponsors deposited with the Trustee
common stock, including contracts for the purchase of certain such securities
(collectively, the "Securities") and cash or an irrevocable letter of credit
issued by a major commercial bank in the amount required for such purchases,
and (ii) the Trustee, in exchange for the Securities, registered on the
registration books of the Trusts the Sponsors' ownership of all Units of the
Trusts. As used herein, the term "Securities" means the common stocks initially
deposited in the Trusts and described in "Portfolio" in Part A and any
additional common stocks acquired and held by the Trusts pursuant to the
provisions of the Indenture.

As of the Initial Date of Deposit, a "Unit" represents a fractional undivided
interest or pro rata share in the Securities and cash of the Trusts as is set
forth in the "Summary of Essential Information." As additional Units are issued
by the Trusts as a result of the deposit of Additional Securities, as described
below, the aggregate value of the Securities in the Trusts will be increased
and the fractional undivided interest in the Trusts represented by each Unit
will be decreased. To the extent that any Units are redeemed by the Trustee,
the fractional undivided interest or pro rata share in such Trusts represented
by each unredeemed Unit will increase, although the actual interest in such
Trusts represented by such fraction will remain unchanged. Units will remain
outstanding until redeemed upon tender to the Trustee by Unitholders, which may
include the Sponsors, or until the termination of the Trust Agreement.

The contracts to purchase Securities deposited initially in the Trusts are
expected to settle in three business days, in the ordinary manner for such
Securities. Settlement of the contracts for Securities is thus expected to take
place prior to the settlement of purchase of Units on the Initial Date of
Deposit.

DEPOSIT OF ADDITIONAL SECURITIES. During the 90-day period following the
Initial Date of Deposit (the "Deposit Period"), the Sponsors may deposit (i)
additional Securities in the Trusts that are substantially similar to the
Securities already deposited in the Trusts ("Additional Securities"), (ii)
contracts to purchase Additional Securities or (iii) cash with instructions to
purchase Additional Securities, in order to create additional Units,
maintaining to the extent practicable the original proportionate relationship
of the number of shares of each Security in the Trusts' portfolios on the
Initial Date of Deposit. These additional

B-1
<PAGE>

Units, which will result in an increase in the number of Units outstanding,
will each represent, to the extent practicable, an undivided interest in the
same number and type of securities of identical issuers as are represented by
Units issued on the Initial Date of Deposit.

The proportionate relationship among the Securities in a Trust will be
adjusted to reflect the occurrence of a stock dividend, a stock split or a
similar event which affects the capital structure of the issuer of a Security
in that Trust but which does not affect a Trust's percentage ownership of the
common stock equity of such issuer at the time of such event. It may not be
possible to maintain the exact original proportionate relationship among the
Securities deposited on the Initial Date of Deposit because of, among other
reasons, purchase requirements, changes in prices, or unavailability of
Securities. Deposits of Additional Securities in each of the Trusts subsequent
to the Deposit Period must replicate exactly the existing proportionate
relationship among the number of shares of Securities in a Trust's portfolio.
Substitute Securities may be acquired under specified conditions when
Securities originally deposited in a Trust are unavailable (see "The Trusts--
Substitution of Securities").

INVESTMENT OBJECTIVE. The Industrial Trust and the Technology Trust each seek
to maximize total return through capital appreciation. There is no guarantee
that this objective will be achieved.

Achievement of the investment objective is dependent upon several factors
including any appreciation or depreciation in value of the Securities, the full
range of economic and market influences affecting corporate profitability, the
financial condition of issuers and the prices of equity securities in general
and the Securities in particular. In addition, because of other factors (i.e.,
Trust sales charges and expenses, unequal weightings of stock, brokerage costs
and any delays in purchasing securities with cash deposited), investors in the
Trusts may not realize as high a total return as the theoretical performance of
the underlying stocks in the Trusts. Since the Sponsors may deposit additional
Securities in connection with the sale of additional Units, the dividend yields
on these Securities may change subsequent to the Initial Date of Deposit.

STRATEGY OF PORTFOLIO SELECTION.

The Industrial Trust. The Industrial Trust seeks to achieve its investment
objective by investing in a fixed portfolio of the 25 best performing stocks on
the S&P 500 Index, as measured by price appreciation, during the twelve-month
period ending December 31, 1999. Price appreciation is measured by the
percentage change in market value of each stock from December 31, 1998 through
December 31, 1999. The strategy involves a 4-step selection process:

Step 1: Calculate the price appreciation for each company listed on the S&P
500 Index over the 12-month period ending December 31, 1999.

Step 2: Eliminate non-ordinary common shares (including preferred
securities, rights and warrants) and foreign issues (except
American Depository Receipts).

Step 3: Select the 25 stocks which have the greatest price appreciation.

Step 4: Of the 25 stocks selected for the Trust, weigh the stocks equally.

B-2
<PAGE>

measured using data from Standard & Poor's Institutional Market Services,
Englewood, Colorado. Price appreciation is measured by the percentage change in
market value of each stock from December 31, 1998 through December 31, 1999.
Technology stocks are identified as those companies that derive the majority of
their revenue from the technology industry, using data from Standard & Poor's
Institutional Market Services, Englewood, Colorado. The strategy also involves
a 4-step selection process:

Step 1: Calculate the number of shares traded daily, for each company
listed on the NASDAQ and the NYSE, on each day the NASDAQ and the
NYSE were open over the twelve-month period ending December 31,
1999.

Step 2: Eliminate non-ordinary common shares (including preferred
securities, rights and warrants) and foreign issues (except
American Depository Receipts).

Step 3: Identity: (i) the 12 stocks that had the highest number of shares
traded on the NASDAQ during the twelve-month period ended December
31, 1999 and from those 12 stocks select the stocks that had price
appreciation of 40% or greater during the same period; and (ii) the
40 stocks listed on the NYSE which had the highest number of shares
traded during the twelve-month period ending December 31, 1999 and
select the technology stocks which had price appreciation of 40% or
greater during the same period.

Step 4: Of the 14 stocks selected for the Trust, weigh the stocks in the
following manner:

. 12% in each of the first two companies to rank in the top half of
both the volume and price categories, first by volume and then by
price;

. 7% in each of the four companies that ranked highest in the
trading volume category and 7% in each of the four companies that
ranked highest in the price appreciation category, excluding any
company that was already selected and received a 12% weighting;
and

. 5% in each of the remaining companies.

THE SECURITIES.

S&P 500 Index. The S&P 500 includes a representative example of leading
companies in leading industries. The S&P 500 is used by 97% of U.S. money
managers and pension plan sponsors and the market value of the 500 companies
contained in this index is approximately $12.318 trillion. Stocks in the S&P
500 represent approximately 80% of the market value of all publicly traded
common stock in the United States although the 500 companies represent only 7%
of the publicly traded companies in the United States.

The S&P 500 is widely regarded as the standard for measuring large-cap U.S.
stock market performance and is also a barometer for overall stock market
performance. The S&P 500 focuses on large cap U.S. companies in leading sectors
such as industrial, transportation, financial and utility. Stocks are chosen
for this index based on market size, liquidity and industry group
representation. NYSE companies make up approximately 90% of the S&P 500, NASDAQ
companies account for approximately 10%.

NASDAQ. Trading on the NASDAQ Stock Market began in February 1971. NASDAQ
stands for the National Association of Securities Dealers Automated Quotations
Systems. NASDAQ is an electronic dealer exchange (there is no physical trading
floor) on which dealers trade securities by setting a buy and sell price. On
NASDAQ, trading is executed through a computer and telecommunications network
and trades more shares per day than any other major United States market.
Approximately 5,100 domestic and foreign companies are listed on the NASDAQ.
The NASDAQ Stock Market is the United States' second-largest securities market
after the New York Stock Exchange. NASDAQ's share volume reached over 202
billion shares in 1998 and dollar volume reached nearly $5.8 trillion. In 1998,
NASDAQ share volume was greater than that of all other U.S. stock markets. In
addition, in 1998 NASDAQ listed 273 U.S. initial public offerings, which is
four times more than any other U.S. stock market.

The NASDAQ stock market is operated by the NASDAQ Stock Market, Inc., an
independent subsidiary of the National Association of Securities Dealers, Inc.
(NASD). Companies listed on the NASDAQ are separated into two major
classifications, the NASDAQ SmallCap Market, for small to medium-sized
companies, and the NASDAQ National Market, for larger companies with higher
capitalization. The NASDAQ Stock Market includes companies of every type and
every size, in every stage of development. Although companies listed on NASDAQ
represent a broad spectrum of industries including agriculture, mining,
construction, manufacturing, transportation, retail, banking and insurance,
just to name a few, the greatest industry concentrations of companies listed on
the NASDAQ are in information technology (including computer technology),
telecommunications, pharmaceuticals, biotechnology, finance, banking and
insurance.

The recent acquisition by the NASD of the American Stock Exchange (AMEX), a
floor-based trading system, has not altered or affected the NASDAQ system. Each
market will continue to function as an independent subsidiary.

NYSE. The New York Stock Exchange (NYSE) is the world's largest equity
market. The NYSE is a floor-based, auction market trading system. In 1999,
there were approximately 809.2 million shares traded each day. Approximately
3,025 domestic and foreign companies are listed on the NYSE with over 242
billion shares outstanding and total market capitalization of nearly $12.3
trillion.

B-4
<PAGE>

The NYSE consists of large, mid-sized and smaller companies in all business
sectors. Moreover, virtually every leading industrial, financial and service
corporation is listed on the NYSE. To be considered for listing on the NYSE, a
company must meet specified levels of net earnings, assets, and trading volume,
and its shares must be widely held by investors.

SUBSTITUTION OF SECURITIES. In the event of a failure to deliver any Security
that has been purchased for the Trusts under a contract ("Failed Securities"),
the Sponsors are authorized under each Trust Agreement to direct the Trustee to
acquire other securities ("Substitute Securities") to make up the original
corpus of the Trusts.

The Substitute Securities must be purchased within 20 days after delivery of
the notice of the failed contract. Where the Sponsors purchase Substitute
Securities in order to replace Failed Securities, the purchase price may not
exceed the purchase price of the Failed Securities and the Substitute
Securities must be substantially similar to the Securities originally
contracted for and not delivered.

Whenever a Substitute Security has been acquired for a Trust, the Trustee
shall, within five days thereafter, notify all Unitholders of that Trust of the
acquisition of the Substitute Security and the Trustee shall, on the next
Distribution Date which is more than 30 days thereafter, make a pro rata
distribution of the amount, if any, by which the cost to the Trust of the
Failed Security exceeded the cost of the Substitute Security.

In the event no substitution is made, the proceeds of the sale of Securities
will be distributed to Unitholders as set forth under "Rights of Unitholders--
Distributions." In addition, if the right of substitution shall not be utilized
to acquire Substitute Securities in the event of a failed contract, the Sponsor
will cause to be refunded the sales charge attributable to such Failed
Securities to all Unitholders, and distribute the principal and dividends, if
any, attributable to such Failed Securities on the next Distribution Date.

RISK CONSIDERATIONS

COMMON STOCK. An investment in Units should be made with an understanding of
the risks inherent in any investment in common stocks including the risk that
the financial condition of the issuers of the Securities may become impaired or
that the general condition of the stock market may worsen (both of which may
contribute directly to a decrease in the value of the Securities and thus in
the value of the Units). Additional risks include those associated with the
right to receive payments from the issuer which is generally inferior to the
rights of creditors of, or holders of, debt obligations or preferred stock
issued by the issuer. Holders of common stocks have a right to receive
dividends only when, if, and in the amounts declared by the issuer's board of
directors and to participate in amounts available for distribution by the
issuer only after all other claims on the issuer have been paid or provided
for. By contrast, holders of preferred stocks usually have the right to receive
dividends at a fixed rate when and as declared by the issuer's board of
directors, normally on a cumulative basis. Dividends on cumulative preferred
stock must be paid before any dividends are paid on common stock and any
cumulative preferred stock dividend which has been omitted is added to future
dividends payable to the holders of such cumulative preferred stock. Preferred
stocks are also usually entitled to rights on liquidation which are senior to
those of common stocks. For these reasons, preferred stocks generally entail
less risk than common stocks.

Moreover, common stocks do not represent an obligation of the issuer and
therefore do not offer any assurance of income or provide the degree of
protection of debt securities. The issuance of debt securities or even
preferred stock by an issuer will create prior claims for payment of principal,
interest and dividends which can adversely affect the ability and inclination
of the issuer to declare or pay dividends on its common stock or

B-5
<PAGE>

the economic interest of holders of common stock with respect to assets of the
issuer upon liquidation or bankruptcy. Further, unlike debt securities which
typically have a stated principal amount payable at maturity (which value will
be subject to market fluctuations prior thereto), common stocks have neither
fixed principal amount nor a maturity and have values which are subject to
market fluctuations for as long as the common stocks remain outstanding. Common
stocks are especially susceptible to general stock market movements and to
volatile increases and decreases in value as market confidence in and
perceptions of the issuers change. These perceptions are based on unpredictable
factors including expectations regarding government, economic, monetary and
fiscal policies, inflation and interest rates, economic expansion or
contraction, and global or regional political, economic or banking crises. The
value of the common stocks in the Trusts thus may be expected to fluctuate over
the life of the Trusts to values higher or lower than those prevailing on the
Initial Date of Deposit.

Unitholders will be unable to dispose of any of the Securities in the Trusts,
and, as such, will not be able to vote the Securities. As the holder of the
Securities, the Trustee will have the right to vote all of the voting stocks in
the Trusts and will vote in accordance with the instructions of the Sponsors.

COMPUTER/COMPUTER TECHNOLOGY INDUSTRIES. The Industrial and Technology Trusts
may be considered to be concentrated in the common stock of companies engaged
in the computer and computer technology industries. As discussed, the value of
the Units of the Trusts may be susceptible to various factors affecting these
industries. Companies in the rapidly changing field of computer and computer
technology face special risks. For example, their products or services may not
prove commercially successful or may become obsolete quickly. As such, the
Trusts may not be an appropriate investment for individuals who are not long-
term investors and whose primary objective is safety of principal or stable
income from their investments. The computer and computer technology-related
industries may be subject to greater governmental regulation than many other
industries and changes in governmental policies and the need for regulatory
approvals may have a material adverse effect on these industries. Additionally,
companies in these industries may be subject to risks of developing computer
technologies, competitive pressures and other factors and are dependent upon
consumer and business acceptance as new computer technologies evolve.

The Sponsors believe that the information summarized above for the
computer/computer technology industries describes some of the more significant
aspects relating to the risks associated with investing in the Trusts which may
have a "concentration" in these industries. The sources of such information are
obtained from research reports as well as other publicly available documents.
While the Sponsors have not independently verified this information, they have
no reason to believe that such information is not correct in all material
respects.

FIXED PORTFOLIO. Unlike a "managed" investment company in which there may be
frequent changes in the portfolio of securities based upon economic, financial
and market analyses, the adverse financial condition of a company will not
result in the elimination of its securities from the portfolio of the Trusts.
In the event a public tender offer is made for a Security or a merger or
acquisition is announced affecting a Security, the Sponsor may instruct the
Trustee to tender or sell the Security on the open market when, in its opinion,
it is in the best interests of the Unitholders to do so. All the Securities in
the Trusts are liquidated or distributed during the Liquidation Period. Since
the Trusts will not sell Securities in response to ordinary market fluctuation,
but only at each of the Trust's termination or upon the occurrence of certain
events, the amount realized upon the sale of the Securities may not be the
highest price attained by an individual Security during the life of a Trust.
See "Administration of Trusts--Trust Supervision." Some of the Securities in
the Trusts

B-6
<PAGE>

may also be owned by other clients of the Sponsors and their affiliates.
However, because these clients may have differing investment objectives, the
Sponsors may sell certain Securities from those accounts in instances where a
sale by the Trusts would be impermissible, such as to maximize return by taking
advantage of market fluctuations. Although the Trusts are regularly reviewed
and evaluated and the Sponsor may instruct the Trustee to sell Securities under
certain limited circumstances, Securities will not be sold by the Trusts to
take advantage of market fluctuations or changes in anticipated rates of
appreciation.

ADDITIONAL SECURITIES. Investors should be aware that in connection with the
creation of additional Units subsequent to the Initial Date of Deposit, the
Sponsors may deposit (i) Additional Securities, (ii) contracts to purchase
Additional Securities or (iii) cash with instructions to purchase Additional
Securities, in each instance maintaining the original proportionate
relationship, subject to adjustment under certain circumstances, of the numbers
of shares of each Security in a Trust. To the extent the price of a Security
increases or decreases between the time cash is deposited with instructions to
purchase the Security and the time the cash is used to purchase the Security,
Units may represent less or more of that Security and more or less of the other
Securities in the Trusts. Brokerage fees (if any) incurred in purchasing
Securities with cash deposited with instructions to purchase the Securities
will be an expense of the Trusts. Price fluctuations between the time of
deposit and the time the Securities are purchased, and payment of brokerage
fees, will affect the value of every Unitholder's Units and the Income per Unit
received by the Trusts.

In particular, Unitholders who purchase Units during the initial offering
period will experience a dilution of their investment as a result of any
brokerage fees paid by the Trusts during subsequent deposits of Additional
Securities purchased with cash deposited. In order to minimize these effects,
the Trusts will try to purchase Securities as near as possible to the
Evaluation Time or at prices as close as possible to the prices used to
evaluate Trust Units at the Evaluation Time. In addition, subsequent deposits
to create such additional Units will not be covered by the deposit of a bank
letter of credit. In the event that the Sponsors do not deliver cash in
consideration for the additional Units delivered, the Trusts may be unable to
satisfy their contracts to purchase the Additional Securities. The failure of
the Sponsors to deliver cash to the Trusts, or any delays in the Trusts
receiving such cash, may have significant adverse consequences for the Trusts.

YEAR 2000 ISSUE. Many existing computer programs use only two digits to
identify a year in the date field and were designed and developed without
considering the impact of the upcoming change in the century. Therefore, the
year "2000" will be incorrectly identified as the year "1900." If not
corrected, many computer applications can fail or create erroneous results by
or at the Year 2000, requiring substantial resources to remedy. The Sponsors
and Trustee believe that the "Year 2000" problem is material to their business
and operations and may have a material adverse effect on the Sponsors' and the
Trustee's results of operations and, in turn, cash available for distribution
by the Trustee. Although the Sponsors and the Trustee are addressing the
problem with respect to their business operations, there can be no assurance
that the "Year 2000" problem will be properly or timely resolved. The "Year
2000" problem may also adversely affect issuers of the Securities contained in
the Trusts to varying degrees based upon various factors. The Sponsors are
unable to predict what effect, if any, the "Year 2000" problem will have on
such issuers.

TERMINATION. Each of the Trusts may be terminated at any time and all
outstanding Units liquidated if the net asset value of a Trust falls below 40%
of the aggregate net asset value of that Trust at the completion of the initial
public offering period. Investors should note that if the net asset value of a
Trust should fall below the applicable minimum value, the Sponsors may then
terminate that Trust, at their sole discretion, prior to the Termination Date
specified in the Summary of Essential Information.

B-7
<PAGE>

LEGAL PROCEEDINGS AND LEGISLATION. At any time after the Initial Date of
Deposit, legal proceedings may be initiated on various grounds, or legislation
may be enacted, with respect to the Securities in the Trusts or to matters
involving the business of the issuer of the Securities. There can be no
assurance that future legal proceedings or legislation, regulation or
deregulation will not have a material adverse effect on the Trusts or will not
impair the ability of the issuers of the Securities to achieve their business
goals.

RETIREMENT PLANS. The Trusts may be well suited for purchase by Individual
Retirement Accounts ("IRAs"), Keogh plans, pension funds and other qualified
retirement plans. Generally, capital gains and income received in each of the
foregoing plans are exempt from Federal taxation. Except with respect to
certain IRAs known as Roth IRAs, distributions from such plans are generally
treated as ordinary income but may, in some cases, be eligible for special 5 or
10 year averaging or tax-deferred rollover treatment. Ten year averaging has
been preserved in very limited circumstances. Holders of Units in IRAs, Keogh
plans and other tax-deferred retirement plans should consult their plan
custodian as to the appropriate disposition of distributions. Investors
considering participation in any such plan should review specific tax laws
related thereto and should consult their attorneys or tax advisors with respect
to the establishment and maintenance of any such plan. Such plans are offered
by McLaughlin, Piven, Vogel Securities, Inc. Fees and charges with respect to
such plans may vary.

Before investing in the Trusts, the trustee or investment manager of an
employee benefit plan (e.g., a pension or profit sharing retirement plan)
should consider among other things whether (i) the investment is prudent under
the Employee Retirement Income Security Act of 1974 ("ERISA"), taking into
account the needs of the plan and all of the facts and circumstances of the
investment in the Trusts; (ii) the investment satisfies the diversification
requirement of Section 404(a)(1)(C) of ERISA; and (iii) the assets of the
Trusts are deemed "plan assets" under ERISA's and the Department of Labor's
definition of "plan assets."

PUBLIC SALE OF UNITS

PUBLIC OFFERING PRICE. The Public Offering Price of the Units for the Trusts
is computed by adding the applicable initial sales charge to the aggregate
value of the Securities (as determined by the Trustee) and any cash held to
purchase Securities, divided by the number of Units of the Trust outstanding.
Valuation of Securities by the Trustee is made at the close of business on the
NYSE on each business day. Securities quoted on a national exchange or NASDAQ
are valued at the closing sale price. Securities not so quoted are valued in
the manner described in the Indenture.

PUBLIC DISTRIBUTION OF UNITS. Units will be distributed to the public at the
Public Offering Price through the Sponsors and may also be distributed through
dealers. The Sponsors intend to qualify the Units for sale in certain states.

VOLUME AND OTHER DISCOUNTS. Units are available at a volume discount from the
Public Offering Price based upon the number of Units purchased. This volume
discount will result in the following reduction of the sales charge applicable
to such purchases:

<TABLE>
<CAPTION>
Industrial and
Technology Trusts
Approximate
Reduced
Number of Units Sales Charge
--------------- -----------------
<S> <C>
25,000 but less than 50,000............................. 3.995%
50,000 but less than 100,000............................ 3.745%
100,000 or more......................................... 3.495%
</TABLE>

B-8
<PAGE>

For transactions of at least 100,000 Units or more, the Sponsors may
negotiate the applicable sales charge and such charge will be disclosed to any
such purchaser.

These discounts will apply to all purchases of Units by the same purchaser.
Units purchased by the same purchasers in separate transactions will be
aggregated for purposes of determining if such purchaser is entitled to a
discount. Such purchaser must own at least the required number of Units at the
time such determination is made. Units held in the name of the spouse of the
purchaser or in the name of a child of the purchaser under 21 years of age are
deemed for the purposes hereof to be registered in the name of the purchaser.
The discount is also applicable to a trustee or other fiduciary purchasing
securities for a single trust estate or single fiduciary account.

Unitholders of prior series of The Pinnacle Family of Trusts (the "Prior
Series") may "rollover" into the Trusts by exchanging units of the Prior Series
for Units of the Trusts at their relative net asset values plus the applicable
sales charge. Unitholders maintaining an account at McLaughlin, Piven, Vogel
Securities, Inc. exercising this option, may purchase such Units subject to a
reduced sales charge of 3.995% for the Industrial and Technology Trusts. An
exchange of units of a Prior Series for Units of the Trusts will generally be a
taxable event. The rollover option described herein will also be available to
investors in the Prior Series who elect to purchase additional Units of the
Trusts (See "Administration of the Trusts--Trust Termination").

Unitholders with a brokerage account at McLaughlin, Piven, Vogel Securities,
Inc. will qualify to receive one trade to buy equity securities any time
following the first Settlement Date of the Trusts and only be charged a $19.50
processing fee.

During the initial offering period, Unitholders who have redeemed units of a
Trust, may purchase Units in an amount up to the amount redeemed, of such
Trust, within thirty days after such redemption, at no sales charge.

Investors who purchase Units of the Trusts through a Keogh Plan, pension fund
or other qualified retirement plan having 25 or more members maintained at
McLaughlin, Piven, Vogel Securities, Inc. will be subject to a reduced sales
charge of 2.0%.

Employees (and their immediate families) of McLaughlin, Piven, Vogel
Securities, Inc. and Reich & Tang Distributors, Inc. (and their affiliates) and
of the special counsel to the Sponsors, may, pursuant to employee benefit
arrangements, purchase Units of the Trusts without a sales charge at a price
equal to the aggregate value of the underlying securities in the Trusts,
divided by the number of Units outstanding. Such arrangements result in less
selling effort and selling expenses than sales to employee groups of other
companies. Resales or transfers of Units purchased under the employee benefit
arrangements may only be made through the Sponsors' secondary market, so long
as it is being maintained.

SPONSORS' PROFITS. The Sponsors will receive a combined gross underwriting
commission equal to up to 4.495% of the Public Offering Price per 100 Units
(equivalent to 4.707% of the net amount invested in the Securities) for the
Industrial and Technology Trusts. Additionally, the Sponsors may realize a
profit on the deposit of the Securities in the Trusts representing the
difference between the cost of the Securities to the Sponsors and the cost of
the Securities to the Trusts (see "Portfolio" in Part A). The Sponsors may
realize profits or sustain losses with respect to Securities deposited in the
Trusts which were acquired from underwriting syndicates of which they were a
member. All or a portion of the Securities deposited in the Trusts may have
been acquired through the Sponsors.

B-9
<PAGE>

During the initial offering period and thereafter to the extent additional
Units continue to be offered by means of this Prospectus, the Underwriter may
also realize profits or sustain losses as a result of fluctuations after the
Initial Date of Deposit in the aggregate value of the Securities and hence in
the Public Offering Price received by the Sponsors for the Units. Cash, if any,
made available to the Sponsors prior to settlement date for the purchase of
Units may be used in the Sponsors' business subject to the limitations of 17
CFR 240.15c3-3 under the Securities Exchange Act of 1934 and may be of benefit
to the Sponsors.

Both upon acquisition of Securities and termination of the Trusts, the
Trustee may utilize the services of the Sponsors for the purchase or sale of
all or a portion of the Securities in the Trusts. The Sponsors may receive
brokerage commissions from the Trusts in connection with such purchases and
sales in accordance with applicable law.

In maintaining a market for the Units (see "Liquidity-Sponsors Repurchase")
the Sponsors will realize profits or sustain losses in the amount of any
difference between the price at which it buys Units and the price at which it
resells such Units.

RIGHTS OF UNITHOLDERS

BOOK-ENTRY UNITS. Ownership of Units of the Trusts will not be evidenced by
certificates. All evidence of ownership of the Units will be recorded in book-
entry form at The Depository Trust Company ("DTC") through an investor's
McLaughlin, Piven, Vogel brokerage account. Units held through DTC will be
deposited by the Sponsors with DTC in the McLaughlin, Piven, Vogel DTC account
and registered in the nominee name CEDE & CO. Individual purchases of
beneficial ownership interest in the Trusts will be made in book-entry form
through DTC. Ownership and transfer of Units will be evidenced and accomplished
directly and indirectly only by book-entries made by DTC and its participants.
DTC will record ownership and transfer of the Units among DTC participants and
forward all notices and credit all payments received in respect of the Units
held by the DTC participants. Beneficial owners of Units will receive written
confirmation of their purchases and sale from their McLaughlin, Piven, Vogel
representative. Transfer, and the requirements therefore, will be governed by
the applicable procedures of DTC and the Unitholder's agreement with the DTC
participant in whose name the Unitholder's Units are registered on the transfer
records of DTC.

DISTRIBUTIONS. Dividends, if any, received by a Trust are credited by the
Trustee to an Income Account for that Trust. Other receipts, including the
proceeds of Securities disposed of, are credited to a Principal Account for
that Trust.

Distributions to each Unitholder from the Income Account are computed as of
the close of business on each Record Date for the following payment date and
consist of an amount substantially equal to such Unitholder's pro rata share of
the income credited to the Income Account, less expenses. Distributions from
the Principal Accounts of the Trusts (other than amounts representing failed
contracts, as previously discussed) will be computed as of each Record Date,
and will be made to the Unitholders of a Trust on or shortly after the
Distribution Date. Proceeds representing principal received from the
disposition of any of the Securities between a Record Date and a Distribution
Date which are not used for redemptions of Units will be held in the Principal
Account and not distributed until the next Distribution Date. Persons who
purchase Units between a Record Date and a Distribution Date will receive their
first distribution on the Distribution Date following the next Record Date.

B-10
<PAGE>

As of each Record Date, the Trustee will deduct from the Income Accounts of
the Trusts, and, to the extent funds are not sufficient therein, from the
Principal Accounts of the Trusts, amounts necessary to pay the expenses of the
Trusts (as determined on the basis set forth under "Trust Expenses and
Charges"). The Trustee also may withdraw from said accounts such amounts, if
any, as it deems necessary to establish a reserve for any applicable taxes or
other governmental charges that may be payable out of the Trusts. Amounts so
withdrawn shall not be considered a part of such Trust's assets until such time
as the Trustee shall return all or any part of such amounts to the appropriate
accounts. In addition, the Trustee may withdraw from the Income and Principal
Accounts such amounts as may be necessary to cover redemptions of Units by the
Trustee.

The dividend distribution per 100 Units, if any, cannot be anticipated and
may be paid as Securities are redeemed, exchanged or sold, or as expenses of
each of the Trusts fluctuate. No distribution need be made from the Income
Account or the Principal Account unless the balance therein is an amount
sufficient to distribute $1.00 per 100 Units.

RECORDS. The Trustee keeps records of the transactions of the Trusts at its
corporate trust office including names, addresses and holdings of all
Unitholders of record, a current list of the Securities and a copy of the
Indenture. Such records are available to Unitholders for inspection at
reasonable times during business hours.

REPORTS TO HOLDERS. The Trustee will furnish Unitholders with each
distribution a statement of the amount of income and the amount of other
receipts, if any, which are being distributed, expressed in each case as a
dollar amount per 100 Units. Within a reasonable time after the end of each
calendar year, the Trustee will furnish to each person who at any time during
the calendar year was a Unitholder of record, a statement showing:

(i) as to the Income Account: dividends, interest and other cash amounts
received, amounts paid for purchases of Substitute Securities and
redemptions of Units, if any, deductions for applicable taxes and fees and
expenses of the Trusts, and the balance remaining after such distributions
and deductions, expressed both as a total dollar amount and as a dollar
amount representing the pro rata share of each 100 Units outstanding on the
last business day of such calendar year;

(ii) as to the Principal Account: the dates of disposition of any
Securities and the net proceeds received therefrom, deductions for payments
of applicable taxes and fees and expenses of the Trusts, amounts paid for
purchases of Substitute Securities and redemptions of Units, if any, and
the balance remaining after such distributions and deductions, expressed
both as a total dollar amount and as a dollar amount representing the pro
rata share of each 100 Units outstanding on the last business day of such
calendar year;

(iii) a list of the Securities held, a list of Securities purchased, sold
or otherwise disposed of during the calendar year and the number of Units
outstanding on the last business day of such calendar year;

(iv) the Redemption Price per 100 Units based upon the last computation
thereof made during such calendar year; and

(v) amounts actually distributed to Unitholders during such calendar year
from the Income and Principal Accounts, separately stated, of the Trusts,
expressed both as total dollar amounts and as dollar amounts representing
the pro rata share of each 100 Units outstanding on the last business day
of such calendar year.

Unitholders will be furnished with evaluations of Securities upon request to
the Trustee in order to comply with Federal and state tax reporting
requirements.

B-11
<PAGE>

LIQUIDITY

SPONSORS REPURCHASE. Unitholders who wish to dispose of their Units should
inquire of the Sponsors as to current market prices prior to making a tender
for redemption. The aggregate value of the Securities will be determined by the
Trustee on a daily basis and computed on the basis set forth under "Trustee
Redemption." The Sponsors do not guarantee the enforceability, marketability or
price of any Securities in the Portfolios or of the Units. The Sponsors may
discontinue the repurchase of Units if the supply of Units exceeds demand, or
for other business reasons. The date of repurchase is deemed to be the date on
which redemption requests are received in proper form, by McLaughlin, Piven,
Vogel Securities, Inc., 30 Wall Street, New York, New York 10005 or Reich &
Tang Distributors Inc., 600 Fifth Avenue, New York, New York 10020. Redemption
requests received after 4 P.M., New York Time, will be deemed to have been
repurchased on the next business day. In the event a market is not maintained
for the Units, a Unitholder may be able to dispose of Units only by tendering
them to the Trustee for redemption.

Units purchased by the Sponsors in the secondary market may be reoffered for
sale by the Sponsors at a price based on (i) the aggregate value of the
Securities in a Trust plus (ii) a 4.495% sales charge (or 4.707% of the net
amount invested) for the Industrial and Technology Trusts plus (iii) a pro rata
portion of amounts, if any, in the Income and Principal Accounts. Any Units
that are purchased by the Sponsors in the secondary market also may be redeemed
by the Sponsors if they determine such redemption to be in their best interest.

The Sponsors may, under certain circumstances, as a service to Unitholders,
elect to purchase any Units tendered to the Trustee for redemption (see
"Liquidity--Trustee Redemption"). Factors that the Sponsors will consider in
making a determination will include the number of Units of all Trusts which
they have in inventory, their estimate of the stability and the time required
to sell such Units and general market conditions. For example, if in order to
meet redemptions of Units the Trustee must dispose of Securities, and if such
disposition cannot be made by the redemption date (three calendar days after
tender), the Sponsors may elect to purchase such Units. Such purchase shall be
made by payment to the Unitholder not later than the close of business on the
redemption date of an amount equal to the Redemption Price on the date of
tender.

TRUSTEE REDEMPTION. At any time prior to the Evaluation Time on the business
day preceding the commencement of the Liquidation Period (approximately fifteen
months from the Date of Deposit), Units may also be tendered to the Trustee for
redemption upon payment of any relevant tax by contacting the Sponsors holding
such Units in street name. In certain instances, additional documents may be
required, such as trust instrument, certificate of corporate authority,
certificate of death or appointment as executor, administrator or guardian. At
the present time there are no specific taxes related to the redemption of
Units. No redemption fee will be charged by the Sponsors or the Trustee. Units
redeemed by the Trustee will be canceled.

Within three business days following a tender for redemption, the Unitholder
will be entitled to receive an amount for each Unit tendered equal to the
Redemption Price per Unit computed as of the Evaluation Time set forth under
"Summary of Essential Information" in Part A on the date of tender. The "date
of tender" is deemed to be the date on which Units are received by the Trustee.
For Units received after the close of trading on the NASDAQ or NYSE (4:00 p.m.
Eastern Time), the date of tender is the next day on which such Exchange is
open for trading, and such Units will be deemed to have been tendered to the
Trustee on such day for redemption at the Redemption Price computed on that
day.

A Unitholder will receive his redemption proceeds in cash and amounts paid on
redemption shall be withdrawn from the Income Accounts, or, if the balance
therein is insufficient, from the Principal Accounts. All

B-12
<PAGE>

other amounts paid on redemption shall be withdrawn from the Principal Account.
The Trustee is empowered to sell Securities in order to make funds available
for redemptions. Such sales, if required, can result in a sale of Securities by
the Trustee at a loss. To the extent Securities are sold, the size and
diversity of the particular Trust will be reduced. The Securities to be sold
will be selected by the Trustee in order to maintain, to the extent
practicable, the proportionate relationship among the number of shares of each
Security. Provision is made in the Indenture under which the Sponsors may, but
need not, specify minimum amounts in which blocks of Securities are to be sold
in order to obtain the best price for the Trusts. While these minimum amounts
may vary from time to time in accordance with market conditions, the Sponsors
believe that the minimum amounts specified will be approximately 100 shares for
readily marketable Securities.

The Redemption Price per Unit is the pro rata share of the Unit in the Trusts
determined by the Trustee on the basis of (i) the cash on hand in the
particular Trust or moneys in the process of being collected, (ii) the value of
the Securities in the Trust as determined by the Trustee, less (a) amounts
representing taxes or other governmental charges payable out of the Trust, (b)
the accrued expenses of the Trust and (c) cash allocated for the distribution
to Unitholders of record as of the business day prior to the evaluation being
made. As of the close of the initial public offering period the Redemption
Price per 100 Units will be reduced to reflect the payment of the per 100 Unit
organization costs to the Sponsors. The Trustee may determine the value of the
Securities in each of the Trusts in the following manner: because the
Securities are listed on national securities exchanges, this evaluation is
based on the closing sale prices on those exchanges. Unless the Trustee deems
these prices inappropriate as a basis for evaluation or if there is no such
closing purchase price, then the Trustee may utilize, at the Trusts' expense,
an independent evaluation service or services to ascertain the values of the
Securities. The independent evaluation service shall use any of the following
methods, or a combination thereof, which it deems appropriate: (i) on the basis
of current bid prices for comparable securities, (ii) by appraising the value
of the Securities on the bid side of the market or (iii) by any combination of
the above.

Any Unitholder tendering 2,500 Units or more of a Trust for redemption may
request, by written notice submitted at the time of tender from the Trustee in
lieu of a cash redemption, a distribution of shares of Securities and cash in
an amount and value equal to the Redemption Price Per Unit as determined as of
the evaluation next following tender. To the extent possible, in kind
distributions ("In Kind Distributions") shall be made by the Trustee through
the distribution of each of the Securities in book-entry form to the account of
the Unitholder's broker-dealer at DTC. An In Kind Distribution will be reduced
by customary transfer and registration charges. The tendering Unitholder will
receive his pro rata number of whole shares of each of the Securities
comprising a Trust portfolio and cash from the Principal Accounts equal to the
balance of the Redemption Price to which the tendering Unitholder is entitled.
If funds in the Principal Account are insufficient to cover the required cash
distribution to the tendering Unitholder, the Trustee may sell Securities in
the manner described above.

The Trustee is irrevocably authorized in its discretion, if the Sponsors do
not elect to purchase a Unit tendered for redemption or if the Sponsors tender
a Unit for redemption, in lieu of redeeming such Unit, to sell such Unit in the
over-the-counter market for the account of the tendering Unitholder at prices
which will return to the Unitholder an amount in cash, net after deducting
brokerage commissions, transfer taxes and other charges, equal to or in excess
of the Redemption Price for such Unit. The Trustee will pay the net proceeds of
any such sale to the Unitholder on the day he would otherwise be entitled to
receive payment of the Redemption Price.

The Trustee reserves the right to suspend the right of redemption and to
postpone the date of payment of the Redemption Price per Unit for any period
during which the NASDAQ, NYSE, or AMEX is closed, other than customary weekend
and holiday closings, or when trading on that Exchange is restricted or during
which

B-13
<PAGE>

(as determined by the Securities and Exchange Commission) an emergency exists
as a result of which disposal or evaluation of the Securities is not reasonably
practicable, or for such other periods as the Securities and Exchange
Commission may by order permit. The Trustee and the Sponsors are not liable to
any person or in any way for any loss or damage which may result from any such
suspension or postponement.

AUTOMATIC REDEMPTION. In the event a transfer of Units from a Unitholder's
McLaughlin, Piven, Vogel brokerage account results in the automatic redemption
of those Units, Unitholders will receive an amount equal to the Redemption
Price per Unit computed as of the Evaluation Time set forth under "Summary of
Essential Information" in Part A on the date of transfer. Automatic redemption
proceeds will be paid within three business days following the tender of a
notification of transfer.

ADMINISTRATION OF THE TRUSTS

TRUST SUPERVISION. Each Trust is a unit investment trust and is not a managed
fund. Traditional methods of investment management for a managed fund typically
involve frequent changes in a portfolio of securities on the basis of economic,
financial and market analyses. The Portfolios of the Trusts, however, will not
be managed and therefore the adverse financial condition of an issuer will not
necessarily require the sale of its Securities from a portfolio. Although the
portfolios of the Trusts are regularly reviewed, because of the formula
employed in selecting the Securities, it is unlikely the Trusts will sell any
of the Securities other than to satisfy redemptions of Units, or to cease
buying Additional Securities in connection with the issuance of additional
Units. However, the Trust Agreement provides that the Sponsors may direct the
disposition of Securities upon the occurrence of certain events including: (i)
default in payment of amounts due on any of the Securities; (ii) institution of
certain legal proceedings; (iii) default under certain documents materially and
adversely affecting future declaration or payment of amounts due or expected;
(iv) determination of the Sponsors that the tax treatment of the Trusts as a
grantor trust would otherwise be jeopardized; or (v) decline in price as a
direct result of serious adverse credit factors affecting the issuer of a
Security which, in the opinion of the Sponsors, will make the retention of the
Security detrimental to the Trusts or the Unitholders. Furthermore, the Trusts
will likely continue to hold a Security and purchase additional shares
notwithstanding its ceasing to be (i) ranked as one of the 25 best performing
stocks on the S&P 500 Index, as measured by price appreciation, or (ii)
included as one of the highest traded stocks on the NASDAQ or NYSE with a price
appreciation of 40% or greater.

In addition, each Trust Agreement provides as follows:

1. If a default in the payment of amounts due on any Security occurs
pursuant to provision (i) above and if the Sponsors fail to give immediate
instructions to sell or hold that Security, the Trustee, within 30 days of
that failure by the Sponsors, shall sell the Security.

2. It is the responsibility of the Sponsors to instruct the Trustee to
reject any offer made by an issuer of any of the Securities to issue new
securities in exchange and substitution for any Security pursuant to a
recapitalization or reorganization, if any exchange or substitution is
effected notwithstanding such rejection, any securities or other property
received shall be promptly sold unless the Sponsors direct that it be
retained.

3. Any property received by the Trustee after the Initial Date of Deposit
as a distribution on any of the Securities in a form other than cash or
additional shares of the Securities, which shall be retained, shall be
promptly sold unless the Sponsors direct that it be retained by the
Trustee. The proceeds of any disposition shall be credited to the Income or
Principal Accounts of a Trust.

B-14

4. The Sponsors are authorized to increase the size and number of Units
of the Trusts by the deposit of Additional Securities, contracts to
purchase Additional Securities or cash or a letter of credit with
instructions to purchase Additional Securities in exchange for the
corresponding number of additional Units from time to time subsequent to
the Initial Date of Deposit, provided that the original proportionate
relationship among the number of shares of each Security in a Trust
established on the Initial Date of Deposit is maintained to the extent
practicable. The Sponsors may specify the minimum numbers in which
Additional Securities will be deposited or purchased. If a deposit is not
sufficient to acquire minimum amounts of each Security, Additional
Securities may be acquired in the order of the Security most under-
represented immediately before the deposit when compared to the original
proportionate relationship. If Securities of an issue originally deposited
are unavailable at the time of the subsequent deposit, the Sponsors may (i)
deposit cash or a letter of credit with instructions to purchase the
Security when it becomes available, or (ii) deposit (or instruct the
Trustee to purchase) either Securities of one or more other issues
originally deposited or a Substitute Security.

TRUST AGREEMENT AND AMENDMENT. The Trust Agreements may be amended by the
Trustee and the Sponsors without the consent of any of the Unitholders to: (i)
cure any ambiguity or to correct or supplement any provision which may be
defective or inconsistent; (ii) change any provision thereof as may be required
by the Securities and Exchange Commission or any successor governmental agency;
or (iii) make such other provisions in regard to matters arising thereunder as
shall not adversely affect the interests of the Unitholders.

The Trust Agreements may also be amended in any respect, or performance of
any of the provisions thereof may be waived, with the consent of investors
holding 66 2/3% of the Units then outstanding for the purpose of modifying the
rights of Unitholders; provided that no such amendment or waiver shall reduce
any Unitholder's interest in the Trusts without his consent or reduce the
percentage of Units required to consent to any such amendment or waiver without
the consent of the holders of all Units. The Trust Agreements may not be
amended, without the consent of the holders of all Units in the Trusts then
outstanding, to increase the number of Units issuable or to permit the
acquisition of any Securities in addition to or in substitution for those
initially deposited in such Trust, except in accordance with the provisions of
the Trust Agreements. The Trustee shall promptly notify Unitholders, in
writing, of the substance of any such amendment.

TRUST TERMINATION. The Trust Agreements provide that a Trust shall terminate
as of the Evaluation Time on the business day preceding the commencement of the
Liquidation Period or upon the maturity, redemption or other disposition, as
the case may be, of the last of the Securities held in such Trust but in no
event is it to continue beyond the Mandatory Termination Date. If the value of
a Trust shall be less than the minimum amount set forth under "Summary of
Essential Information" in Part A, the Trustee may, in its discretion, and
shall, when so directed by the Sponsors, terminate such Trust. Each Trust may
also be terminated at any time with the consent of the investors holding 100%
of the Units then outstanding. The Trustee may utilize the services of the
Sponsors for the sale of all or a portion of the Securities in the Trusts, and
in so doing, the Sponsors will determine the manner, timing and execution of
the sales of the underlying Securities. Any brokerage commissions received by
the Sponsors from the Trusts in connection with such sales will be in
accordance with applicable law. In the event of termination, written notice
thereof will be sent by the Trustee to all Unitholders. Such notice will
provide Unitholders with the following three options by which to receive their
pro rata share of the net asset value of the Trusts and requires their election
of one of the three options by notifying the Trustee by returning a properly
completed election request (to be supplied to Unitholders of at least 2,500
Units of a Trust prior to the commencement of the Liquidation Period):

B-15
<PAGE>

1. a Unitholder who owns at least 2,500 units and whose interest in a
Trust will entitle it to receive at least one share of each underlying
Security will have its Units redeemed on or about the commencement of the
Liquidation Period. This will be accomplished by distribution of the
Unitholder's pro rata share of the net asset value of the Trust on such
date distributed in kind to the extent represented by whole shares of
underlying Securities and the balance in cash within three business days
next following the commencement of the Liquidation Period. Unitholders
subsequently selling such distributed Securities will incur brokerage costs
when disposing of such Securities. Unitholders should consult their own tax
adviser in this regard;

2. to receive in cash such Unitholder's pro rata share of the net asset
value of a Trust derived from the sale by the Sponsors as the agents of the
Trustee of the underlying Securities during the Liquidation Period. The
Unitholder's pro rata share of its net assets of a Trust will be
distributed to such Unitholder within three days of the settlement of the
trade of the last Security to be sold; and/or

3. to invest such Unitholder's pro rata share of the net assets of a
Trust derived from the sale by the Sponsors as agents of the Trustee of the
underlying Securities in units of a subsequent series of The Pinnacle
Family of Trusts (the "New Series") provided one is offered. It is expected
that a special redemption and liquidation will be made of all Units of the
Trust held by a Unitholder (a "Rollover Unitholder") who affirmatively
notifies the Trustee on or prior to the Rollover Notification Date set
forth in the "Summary of Essential Information" for the Trusts in Part A.
The Units of a New Series will be purchased by the Unitholder within three
business days of the settlement of the trade for the last Security to be
sold. Such purchaser will be entitled to a reduced sales charge upon the
purchase of units of the New Series. It is expected that the terms of the
New Series will be substantially the same as the terms of the Trusts
described in this Prospectus, and that similar options with respect to the
termination of such New Series will be available. The availability of this
option does not constitute a solicitation of an offer to purchase Units of
a New Series or any other security. A Unitholder's election to participate
in this option will be treated as an indication of interest only. At any
time prior to the purchase by the Unitholder of units of a New Series such
Unitholder may change his investment strategy and receive, in cash, the
proceeds of the sale of the Securities. An election of this option will not
prevent the Unitholder from recognizing taxable gain or loss (except in the
case of a loss, if and to the extent that Securities contained in the New
Series are treated as substantially identical to Securities held by a
Trust) as a result of the liquidation, even though no cash will be
distributed to pay any taxes. Unitholders should consult their own tax
advisers in this regard.

Unitholders who do not make any election will be deemed to have elected to
receive the termination distribution in cash (option number 2).

The Sponsors have agreed that, to the extent they effect the sales of
underlying Securities for the Trustee, in the case of the second and third
options during the Liquidation Period such sales will be free of brokerage
commissions. The Sponsors, on behalf of the Trustee, will sell the Securities
by the last business day of the Liquidation Period unless prevented by unusual
and unforeseen circumstances, such as, among other reasons, a suspension in
trading of a Security, the close of a stock exchange, outbreak of hostilities
and collapse of the economy. The Redemption Price Per 100 Units upon the
settlement of the last sale of Securities during the Liquidation Period will be
distributed to Unitholders in redemption of such Unitholders' interest in a
Trust.

Depending on the amount of proceeds to be invested in Units of the New Series
and the amount of other orders for Units in the New Series, the Sponsors may
purchase a large amount of securities for the New Series in a short period of
time. The Sponsors' buying of securities may tend to raise the market prices of
these

B-16
<PAGE>

securities. The actual market impact of the Sponsors' purchases, however, is
currently unpredictable because the actual amount of securities to be purchased
and the supply and price of those securities is unknown. A similar problem may
occur in connection with the sale of Securities during the Liquidation Period;
depending on the number of sales required, the prices of and demand for
Securities, such sales may tend to depress the market prices and thus reduce
the proceeds of such sales. The Sponsors believe that the sale of underlying
Securities over the Liquidation Period described above is in the best interest
of a Unitholder and may mitigate the negative market price consequences
stemming from the trading of large amounts of Securities. The Securities may be
sold in fewer than seven days if, in the Sponsor's judgment, such sales are in
the best interest of Unitholders. The Sponsors, in implementing such sales of
securities on behalf of the Trustee, will seek to maximize the sales proceeds
and will act in the best interests of the Unitholders. There can be no
assurance, however, that any adverse price consequences of heavy trading will
be mitigated.

Section 17(a) of the Investment Company Act of 1940 generally prohibits
principal transactions between registered investment companies and their
affiliates. Pursuant to an exemptive order issued by the SEC, each terminating
Series of The Pinnacle Family of Trusts can sell Duplicated Securities directly
to a New Series. The exemption will enable the Trusts to eliminate commission
costs on these transactions. The price for those securities transferred will be
the closing sale price on the sale date on the national securities exchange
where the securities are principally traded, as certified and confirmed by the
Trustee.

The Sponsors may for any reason, in their sole discretion, decide not to
sponsor any subsequent series of the Trusts, without penalty or incurring
liability to any Unitholder. If the Sponsors so decide, the Sponsors will
notify the Trustee of that decision, and the Trustee will notify the
Unitholders. All Unitholders will then elect either option 1, if eligible, or
option 2.

By electing to rollover into the New Series, the Unitholder indicates his
interest in having his terminating distribution from the Trusts invested only
in the New Series created following termination of the Trusts; the Sponsors
expect, however, that a similar rollover program will be offered with respect
to all subsequent series of the Trusts, thus giving Unitholders an opportunity
to elect to rollover their terminating distributions into a New Series. The
availability of the rollover privilege does not constitute a solicitation of
offers to purchase units of a New Series or any other security. A Unitholder's
election to participate in the rollover program will be treated as an
indication of interest only. The Sponsors intend to coordinate the date of
deposit of a future series so that the terminating trusts will terminate
contemporaneously with the creation of a New Series. The Sponsors reserve the
right to modify, suspend or terminate the rollover privilege at any time.

In the event the Sponsors determine that a redemption in kind and subsequent
investment in a New Series by a Unitholder may be accomplished in a manner that
will not result in the recognition of gain or loss for Federal income tax
purposes with respect to any Securities included in the portfolio of the New
Series, Unitholders will be notified at least 30 days prior to the Rollover
Notification Date of the procedures and process necessary to facilitate such
tax treatment.

Co. LLC ("ING"). The transaction is expected to close within 30 days of the
date of this Prospectus. Upon closing of the transaction, substantially all of
the unit trust personnel of Reich & Tang will become employees of ING and ING
will assume the ongoing business operations of Reich & Tang's unit investment
trust business. Upon closing, Reich & Tang will resign as sponsor of the Trust
and ING expects to be appointed by the Trustee as the successor sponsor
assuming all the sponsor's obligations and duties under the Indenture. ING is a
wholly owned indirect subsidiary of ING Group. ING Group, among the leading
global financial services organizations, is engaged in asset management,
banking and insurance activities in 60 countries worldwide with over 82,000

The information included herein is only for the purpose of informing
investors as to the financial responsibility of the Sponsors and their ability
to carry out its contractual obligations. The Sponsors will be under no
liability to Unitholders for taking any action, or refraining from taking any
action, in good faith pursuant to the Trust Agreement, or for errors in
judgment except in cases of its own willful misfeasance, bad faith, gross
negligence or reckless disregard of its obligations and duties.

The Sponsors may each resign at any time by delivering to the Trustee an
instrument of resignation executed by the Sponsors. If at any time either of
the Sponsors shall resign or fail to perform any of their duties under a Trust
Agreement or become incapable of acting or become bankrupt or their affairs are
taken over by public authorities, then the Trustee may either (i) appoint a
successor sponsor; (ii) terminate a Trust Agreement and liquidate the Trusts;
or (iii) continue to act as Trustee without terminating a Trust Agreement. Any
successor sponsor appointed by the Trustee shall be satisfactory to the Trustee
and, at the time of appointment, shall have a net worth of at least $1,000,000.

THE TRUSTEE. The Trustee is The Chase Manhattan Bank, with its principal
executive office located at 270 Park Avenue, New York, New York 10017 (800)
428-8890 and its unit investment trust office at Four New York Plaza, New York,
New York 10004. The Trustee is subject to supervision by the Superintendent of
Banks of the State of New York, the Federal Deposit Insurance Corporation and
the Board of Governors of the Federal Reserve System.

The Trustee shall not be liable or responsible in any way for taking any
action, or for refraining from taking any action, in good faith pursuant to the
Trust Agreement, or for errors in judgment; or for any disposition of any
moneys, Securities or Units in accordance with the Trust Agreement, except in
cases of its own willful misfeasance, bad faith, gross negligence or reckless
disregard of its obligations and duties;

B-18
<PAGE>

provided, however, that the Trustee shall not in any event be liable or
responsible for any evaluation made by any independent evaluation service
employed by it. In addition, the Trustee shall not be liable for any taxes or
other governmental charges imposed upon or in respect of the Securities or the
Trusts which it may be required to pay under current or future law of the
United States or any other taxing authority having jurisdiction. The Trustee
shall not be liable for depreciation or loss incurred by reason of the sale by
the Trustee of any of the Securities pursuant to the Trust Agreement. The
Trustee has not participated in the selection of the Trusts' Securities.

For further information relating to the responsibilities of the Trustee under
the Trust Agreement, reference is made to the material set forth under "Rights
of Unitholders."

The Trustee may resign by executing an instrument in writing and filing the
same with the Sponsors, and mailing a copy of a notice of resignation to all
Unitholders. In such an event the Sponsors are obligated to appoint a successor
Trustee as soon as possible. In addition, if the Trustee becomes incapable of
acting or becomes bankrupt or its affairs are taken over by public authorities,
the Sponsors may remove the Trustee and appoint a successor as provided in the
Trust Agreement. Notice of such removal and appointment shall be mailed to each
Unitholder by the Sponsors. If upon resignation of the Trustee no successor has
been appointed and has accepted the appointment within thirty days after
notification, the retiring Trustee may apply to a court of competent
jurisdiction for the appointment of a successor. The resignation or removal of
the Trustee becomes effective only when the successor Trustee accepts its
appointment as such or when a court of competent jurisdiction appoints a
successor Trustee. Upon execution of a written acceptance of such appointment
by such successor Trustee, all the rights, powers, duties and obligations of
the original Trustee shall vest in the successor.

Any corporation into which the Trustee may be merged or with which it may be
consolidated, or any corporation resulting from any merger or consolidation to
which the Trustee shall be a party, shall be the successor Trustee. The Trustee
must always be a banking corporation organized under the laws of the United
States or any State and have at all times an aggregate capital, surplus and
undivided profits of not less than $2,500,000.

TRUST EXPENSES AND CHARGES

Investors will reimburse the Sponsors for all or a portion of the estimated
costs incurred in organizing and offering the Trusts (collectively, the
"organization costs")--including the cost of the initial preparation and
execution of the Trust Agreements, registration of the Trusts and the Units
under the Investment Company Act of 1940 and the Securities Act of 1933 and
state registration fees, the initial fees and expenses of the Trustee, legal
expenses and other actual out-of-pocket costs. The estimated organization costs
will be paid from the assets of the Trusts as of the close of the initial
public offering period (which may be between 30 and 90 days). To the extent
that actual organization costs are less than the estimated amount, only the
actual organization costs will be deducted from the assets of the Trusts. To
the extent that actual organization costs are greater than the estimated
amount, only the estimated organization costs included in the Public Offering
Price will be reimbursed to the Sponsors. All advertising and selling expenses,
as well as any organizational costs not paid by the Trusts, will be borne by
the Sponsors at no cost to the Trusts.

B-19
<PAGE>

The Sponsors will receive, for portfolio supervisory services to the Trusts,
an Annual Fee in the amount set forth under "Summary of Essential Information"
in Part A. The Sponsors' fee may exceed the actual cost of providing portfolio
supervisory services for the Trusts, but at no time will the total amount
received for portfolio supervisory services rendered to all series of The
Pinnacle Family of Trusts in any calendar year exceed the aggregate cost to the
Sponsors of supplying such services in such year. (See "Administration of the
Trusts--Trust Supervision.")

The Trustee will receive, for its ordinary recurring services to the Trusts,
an annual fee in the amount set forth under "Summary of Essential Information"
in Part A. For a discussion of the services performed by the Trustee pursuant
to its obligations under the Trust Agreement, see "Administration of the
Trusts" and "Rights of Unitholders."

The Trustee's fees applicable to the Trusts are payable as of each Record
Date from the Income Accounts of the Trusts to the extent funds are available
and then from the Principal Accounts. Both the Sponsors' and the Trustee's fees
may be increased without approval of the Unitholders by amounts not exceeding
proportionate increases in consumer prices for services as measured by the
United States Department of Labor's Consumer Price Index entitled "All Services
Less Rent."

The following additional charges are or may be incurred by the Trusts: (i)all
expenses (including counsel fees) of the Trustee incurred and advances made in
connection with its activities under the Trust Agreements, including the
expenses and costs of any action undertaken by the Trustee to protect the
Trusts and the rights and interests of the Unitholders; (ii) fees of the
Trustee for any extraordinary services performed under the Trust Agreements;
indemnification of the Trustee for any loss or liability accruing to it without
gross negligence, bad faith or willful misconduct on its part, arising out of
or in connection with its acceptance or administration of the Trusts; (iii)
indemnification of the Sponsors for any losses, liabilities and expenses
incurred in acting as sponsors of the Trusts without gross negligence, bad
faith or willful misconduct on its part; and (iv) all taxes and other
governmental charges imposed upon the Securities or any part of the Trusts (no
such taxes or charges are being levied, made or, to the knowledge of the
Sponsors, contemplated). The above expenses, including the Trustee's fees, when
paid by or owing to the Trustee are secured by a first lien on the Trusts to
which such expenses are charged. In addition, the Trustee is empowered to sell
the Securities in order to make funds available to pay all expenses.

Unless the Sponsors otherwise direct, the accounts of the Trusts shall be
audited not less than annually by independent public accountants selected by
the Sponsors. The expenses of the audit shall be an expense of the Trusts. So
long as the Sponsors maintain a secondary market, the Sponsors will bear any
audit expense which exceeds $.50 cents per 100 Units. Unitholders covered by
the audit during the year may receive a copy of the audited financial
statements upon request.

REINVESTMENT PLAN

Income and principal distributions on Units (other than the final
distribution in connection with the termination of the Trusts) may be
reinvested by participating in the Trusts' Reinvestment Plan. Under the plan,
the Units acquired for participants will be either Units already held in
inventory by the Sponsors or new Units created by the Sponsors' deposit of
Additional Securities as described in "The Trusts--Deposit of Additional
Securities" in this Part B. Units acquired by reinvestment will be subject to a
reduced sales charge of 1.00%. Unitholders who participate in the Reinvestment
Plan will nevertheless be subject to tax on their distributions in the manner
described under "Tax Status." Investors should inform their broker when
purchasing their Units

B-20
<PAGE>

if they wish to participate in the Reinvestment Plan. Thereafter, Unitholders
should contact their broker if they wish to modify or terminate their election
to participate in the Reinvestment Plan. In order to enable a Unitholder to
participate in the Reinvestment Plan, with respect to a particular distribution
on their Units, such notice must be made at least three business days prior to
the Record Date for such distribution. Each subsequent distribution of income
or principal on the participant's Units will be automatically applied by the
Trustee to purchase additional Units of the Trusts. The Sponsors reserve the
right to demand, modify or terminate the Reinvestment Plan at any time without
prior notice. The Reinvestment Plan for the Trusts may not be available in all
states.

TAX STATUS

This is a general discussion of certain of the Federal income tax
consequences of the purchase, ownership and disposition of the Units. The
summary is limited to investors who hold the Units as "capital assets"
(generally, property held for investment) within the meaning of Section 1221 of
the Internal Revenue Code. Unitholders should consult their tax advisers in
determining the Federal, state, local and any other tax consequences of the
purchase, ownership and disposition of Units.

In rendering the opinion set forth below, Battle Fowler LLP has examined the
Agreement, the final form of Prospectus dated the date hereof and the documents
referred to therein, among others, and has relied on the validity of said
documents and the accuracy and completeness of the facts set forth therein. In
the Opinion of Battle Fowler LLP, special counsel for the Sponsors, under
existing law:

1. The Trusts will be classified as grantor trusts for Federal income tax
purposes and not as partnerships or associations taxable as corporations.
Classification of the Trusts as grantor trusts will cause the Trusts not to
be subject to Federal income tax, and will cause the Unitholders of the
Trusts to be treated for Federal income tax purposes as the owners of a pro
rata portion of the assets of the Trusts. All income received by the Trusts
will be treated as income of the Unitholders in the manner set forth below.

2. The Trusts are not subject to the New York Franchise Tax on Business
Corporations or the New York City General Corporation Tax. For a Unitholder
who is a New York resident, however, a pro rata portion of all or part of
the income of the Trusts will be treated as income of the Unitholder under
the income tax laws of the State and City of New York. Similar treatment
may apply in other states.

3. During the 90-day period subsequent to the initial issuance date, the
Sponsors reserve the right to deposit Additional Securities that are
substantially similar to those deposited in initially establishing the
Trusts. This retained right falls within the guidelines promulgated by the
IRS and should not affect the taxable status of the Trusts.

A taxable event will generally occur with respect to each Unitholder when the
Trusts dispose of a Security (whether by sale, exchange or redemption) or upon
the sale, exchange or redemption of Units by the Unitholder. The price a
Unitholder pays for its Units, including sales charges, is allocated among its
pro rata portion of each Security held by the Trusts (in proportion to the fair
market values thereof on the date the Unitholder purchases its Units) in order
to determine its initial cost for its pro rata portion of each Security held by
the Trusts.

For Federal income tax purposes, a Unitholder's pro rata portion of dividends
paid with respect to a Security held by the Trusts is taxable as ordinary
income to the extent of such corporation's current or

B-21
<PAGE>

accumulated earnings and profits. A Unitholder's pro rata portion of dividends
paid on a Security that exceed current and accumulated earnings and profits
will first reduce a Unitholder's tax basis in the Security, and to the extent
that such dividends exceed a Unitholder's tax basis in the Security will
generally be treated as a capital gain.

A Unitholder's portion of gain, if any, upon the sale, exchange or redemption
of Units or the disposition of Securities held by the Trusts will generally be
considered a capital gain and will be long-term if the Unitholder has held its
Units (and the Trust has held the Securities) for more than one year. Capital
gains realized by corporations are generally taxed at the same rates applicable
to ordinary income, but non-corporate taxpayers who realize long-term capital
gains may be subject to a reduced tax rate of 20%, rather than the "regular"
maximum tax rate of 39.6%. Tax rates may increase prior to the time when
Unitholders may realize gains from the sale, exchange or redemption of the
Units or Securities.

A Unitholder's portion of loss, if any, upon the sale or redemption of Units
or the disposition of Securities held by the Trusts will generally be
considered a capital loss and will be long-term if the Unitholder has held its
Units (and the Trust has held the Securities) for more than one year. Capital
losses are deductible to the extent of capital gains; in addition, up to $3,000
of capital losses ($1,500 for married individuals filing separately) recognized
by non-corporate Unitholders may be deducted against ordinary income.

A Unitholder that itemizes its deductions may also deduct its pro rata share
of the fees and expenses of the Trusts, but only to the extent that such
amounts, together with the Unitholder's other miscellaneous deductions, exceed
2% of its adjusted gross income. The deduction of fees and expenses may also be
limited by Section 68 of the Code, which reduces the amount of itemized
deductions that are allowed for individuals with incomes in excess of certain
thresholds.

After the end of each calendar year, the Trustee will furnish to each
Unitholder an annual statement containing information relating to the dividends
received by the Trusts on the Securities, the gross proceeds received by the
Trusts from the disposition of any Security, and the fees and expenses paid by
the Trusts. The Trustee will also furnish annual information returns to each
Unitholder and to the Internal Revenue Service.

A corporation (other than an S corporation and certain ineligible
corporations) that owns Units will generally be entitled to a 70% dividends
received deduction with respect to its pro rata portion of dividends taxable as
ordinary income received by the Trusts from a domestic corporation or from a
qualifying foreign corporation in the same manner as if such corporation
directly owned the Securities paying such dividends. However, a corporation
owning Units should be aware that Sections 246 and 246A of the Code impose
additional limitations on the eligibility of dividends for the 70% dividends
received deduction. These limitations include a requirement that stock (and
therefore Units) must generally be held at least 46 days (as determined under
Section 246(c) of the Code) during the 90-day period beginning on the date that
is 45 days before the date on which the stock becomes ex-dividend. Moreover,
the allowable percentage of the deduction will be reduced if a corporate
Unitholder owns stock (or Units) the financing of which is directly
attributable to indebtedness incurred by such corporation.

As discussed in the section "Administration of the Trusts--Trust
Termination," each Unitholder may have three options in receiving its
termination distributions, namely (i) to receive its pro rata share of the
underlying Securities in kind, (ii) to receive cash upon liquidation of its pro
rata share of the underlying Securities, or (iii) to invest the amount of cash
it will receive upon the liquidation of its pro rata share of the underlying
Securities in units of a future series of the Trusts (if one is offered) at a
reduced sales charge. A

B-22
<PAGE>

Unitholder that chooses option (i) should be treated as merely exchanging its
undivided pro rata ownership of Securities held by the Trusts for sole
ownership of a proportionate share of Securities, and therefore the transaction
should be tax free to the extent the Securities are received.

Entities that generally qualify for an exemption from Federal income tax,
such as many pension trusts, are nevertheless taxed under Section 511 of the
Code on unrelated business taxable income. Unrelated business taxable income is
income from a trade or business regularly carried on by the tax-exempt entity
that is unrelated to the entity's exempt purpose. Unrelated business taxable
income generally does not include dividend or interest income or gain from the
sale of investment property, unless such income is derived from property that
is debt-financed or is dealer property. A tax-exempt entity's dividend income
from the Trusts and gain from the sale of Units in the Trusts or the Trusts'
sale of Securities is not expected to constitute unrelated business taxable
income to such tax-exempt entity unless the acquisition of the Unit itself is
debt-financed or constitutes dealer property in the hands of the tax-exempt
entity.

Prospective investors are urged to consult their own tax advisers concerning
the Federal, state, local and any other tax consequences of the purchase,
ownership and disposition of Units prior to investing in the Trusts.

OTHER MATTERS

LEGAL OPINIONS. The legality of the Units offered hereby and certain matters
relating to Federal tax law have been passed upon by Battle Fowler LLP, 75 East
55th Street, New York, New York 10022 as counsel for the Sponsor. Carter,
Ledyard & Milburn, Two Wall Street, New York, New York 10005 have acted as
counsel for the Trustee.

INDEPENDENT AUDITORS. The Statements of Financial Condition, including the
Portfolios, are included herein in reliance upon the report of Ernst & Young
LLP, independent auditors, and upon the authority of said firm as experts in
accounting and auditing.

PERFORMANCE INFORMATION. Total returns, average annualized returns or
cumulative returns for various periods of the strategy, the related index and
the Trusts may be included from time to time in advertisements, sales
literature and reports to current or prospective investors. Total return shows
changes in Unit price during the period plus any dividends and capital gains,
divided by the original public offering price. Average annualized returns show
the average return for stated periods of longer than a year. Sales material may
also include an illustration of the cumulative results of like annual
investments in a strategy during an accumulation period and like annual
withdrawals during a distribution period. Figures for actual portfolios will
reflect all applicable expenses and, unless otherwise stated, the maximum sales
charge. No provision is made for any income taxes payable. Similar figures may
be given for the Trusts applying the investment strategies to other indexes.
Returns may also be shown on a combined basis. Trust performance may be
compared to performance on a total return basis of the NASDAQ, NYSE or similar
exchanges, as well as the DJIA, S&P 500 Index or other similar indices. In
addition, total return comparisons may be made to performance data from Lipper
Analytical Services, Inc., Morningstar Publications, Inc., Standard & Poor's
Institutional Market Services and Center for Research in Security Prices (CRSP)
at the University of Chicago or from publications such as The Wall Street
Journal, Money, The New York Times, U.S. News and World Report, Business Week,
Forbes or Fortune. As with other performance data, performance comparisons
should not be considered representative of the Trusts' relative performance for
any future period.

B-23
<PAGE>

Pending the approval of the National Association of Securities Dealers
Regulation, the Sponsors may also include, in advertisements, sales literature
and reports to current or prospective investors, the performance of
hypothetical portfolios to which the Sponsors have applied the same investment
objectives and selection strategies, as well as back-tested data of the
historical performance of such strategies, as described in "The Trusts--The
Securities" and which the Sponsors intend to apply to the selection of
securities for the Trusts. This performance information is intended to
illustrate each of the Trust's strategies and should not be interpreted as
indicative of the future performance of the Trusts.

website that contains reports, proxy and information statements and other
information regarding the Trusts which is filed electronically with the SEC.
The SEC's Internet address is http:www.sec.gov. Offering materials for the sale
of these Units available through the Internet are not being offered directly or

Re: The Pinnacle Family of Trusts, Industrial Trust Series IV
and Technology Trust Series IV
---------------------------------------------------------

Dear Sirs:

We have acted as special counsel for McLaughlin, Piven, Vogel Securities,
Inc. and Reich & Tang Distributors, Inc., as Depositors, Sponsors and Principal
Underwriters (collectively, the "Depositors") of The Pinnacle Family of Trusts,
Industrial Trust Series IV and Technology Trust Series IV (collectively referred
to as the "Trust") in connection with the issuance by the Trust of units of
fractional undivided interest (the "Units") in the Trust. Pursuant to the Trust
Agreements referred to below, the Depositors have transferred to the Trust
certain securities and contracts to purchase certain securities together with an
irrevocable letter of credit to be held by the Trustee (as defined below) upon
the terms and conditions set forth in the Trust Agreements. (All securities to
be acquired by the Trust are collectively referred to as the "Securities.")
<PAGE>

January 19, 2000

In connection with our representation, we have examined copies of the
following documents relating to the creation of the Trust and the issuance and
sale of the Units: (a) the Trust Indenture and Agreement and related Reference
Trust Agreements, each of even date herewith, relating to the Trust
(collectively, the "Trust Agreements") among the Depositors and The Chase
Manhattan Bank, as Trustee (the "Trustee"); (b) the Notification of Registration
on Form N-8A and the Registration Statement on Form N-8B-2, as amended, relating
to the Trust, as filed with the Securities and Exchange Commission (the
"Commission") pursuant to the Investment Company Act of 1940 (the "1940 Act");
(c) the Registration Statement on Form S-6 (Registration No. 333-94109) filed
with the Commission pursuant to the Securities Act of 1933 (the "1933 Act"), and
all Amendments thereto (said Registration Statement, as amended by said
Amendment(s) being herein called the "Registration Statement"); (d) the proposed
form of final Prospectus (the "Prospectus") relating to the Units, which is
expected to be filed with the Commission this day; (e) certified resolutions of
the Board of Directors of Reich & Tang Distributors, Inc. and of the Board of
Directors of McLaughlin, Piven, Vogel Securities, Inc. authorizing the execution
and delivery by the Depositors of the Trust Agreements and the consummation of
the transactions contemplated thereby; (f) the Certificate of Incorporation of
Reich & Tang Distributors, Inc.; (g) the Certificate of Incorporation, the
Certificates of Amendment of the Certificate of Incorporation and the Bylaws of
McLaughlin, Piven, Vogel Securities, Inc.; and (h) a certificate of an
authorized officer of Reich & Tang Distributors, Inc. with respect to certain
factual matters contained therein.

We have examined the Order of Exemption from certain provisions of
Sections 11(a) and 11(c) of the 1940 Act, filed on behalf of Reich & Tang
Distributors L.P.(the predecessor to Reich & Tang Distributors, Inc.); Equity
Securities Trust (Series 1, Signature Series and Subsequent Series), Mortgage
Securities Trust (CMO Series 1 and Subsequent Series), Municipal Securities
Trust, Series 1 (and Subsequent Series) (including Insured Municipal Securities
Trust, Series 1 (and Subsequent Series and 5th Discount Series and Subsequent
Series)); New York Municipal Trust (Series 1 and Subsequent Series); and A
Corporate Trust (Series 1 and Subsequent Series) granted on October 9, 1996. In
addition, we have examined the Order of Exemption from certain provisions of
Sections 2(a)(32), 2(a)(35), 22(d) and 26(a)(2) of the 1940 Act and Rule 22C-1
thereunder, filed on behalf of Reich & Tang Distributors L.P.; Equity Securities
Trust; Mortgage Securities Trust; Municipal Securities Trust (including Insured
Municipal Securities Trust); New York Municipal Trust; A Corporate Trust; Schwab
Trusts; and all presently outstanding and subsequently issued series of these
trusts and all subsequently issued series of unit investment trusts sponsored by
Reich & Tang Distributors L.P. granted on October 29, 1997.

We have not reviewed the financial statements, compilation of the
Securities held by the Trust, or other financial or statistical data contained
in the Registration Statement and the

Prospectus, as to which you have been furnished with the reports of the
accountants appearing in the Registration Statement and the Prospectus.

In addition, we have assumed the genuineness of all agreements,
instruments and documents submitted to us as originals and the conformity to
originals of all copies thereof submitted to us. We have also assumed the
genuineness of all signatures and the legal capacity of all persons executing
agreements, instruments and documents examined or relied upon by us.

Statements in this opinion as to the validity, binding effect and
enforceability of agreements, instruments and documents are subject to: (i)
limitations as to enforceability imposed by bankruptcy, reorganization,
moratorium, insolvency and other laws of general application relating to or
affecting the enforceability of creditors' rights, and (ii) limitations under
equitable principles governing the availability of equitable remedies.

We are not admitted to the practice of law in any jurisdiction but the
State of New York and we do not hold ourselves out as experts in or express any
opinion as to the laws of other states or jurisdictions except as to matters of
Federal and Delaware corporate law.

Based exclusively on the foregoing, we are of the opinion that under
existing law:

(1) The Trust Agreements have been duly authorized and entered into by an
authorized officer of each of the Depositors and are a valid and binding
obligation of the Depositors in accordance with their respective terms.

(2) The registration of the Units on the registration books of the Trust
by the Trustee has been duly authorized by the Depositors in accordance with the
provisions of the Trust Agreements and issued for the consideration contemplated
therein, will constitute fractional undivided interests in the Trust, will be
entitled to the benefits of the Trust Agreements, and will conform in all
material respects to the description thereof contained in the Prospectus. Upon
payment of the consideration for the Units as provided in the Trust Agreements
and the Registration Statement, the Units will be fully paid and non-assessable
by the Trust.

We hereby consent to the filing of this opinion as an exhibit to the
Registration Statement and to the use of our name in the Registration Statement
and in the Prospectus under the headings "Tax Status" and "Legal Opinions." We
authorize you to deliver copies of this opinion to the Trustee and the Trustee
may rely on this opinion as fully and to the same extent as if it had been
addressed to it.
