(2) The second distribution under the quarterly distribution plan represents a 1-month distribution; subsequent quarterly
    distributions will be regular 3-month distributions.
(3) The second distribution under the semi-annual distribution plan represents a 1-month distribution; subsequent semi-annual
    distributions will be regular 6-month distributions.
</TABLE>
 
+ Interest for Unitholders of this series began to accrue as of the Date of
Deposit. Units purchased on the Date of Deposit will have $.12 of accrued
interest that will be added to the Public Offering Price on the Settlement Date.
After provision for expenses of the Fund, the daily rate of accrual from the
Date of Deposit to the first Record Date is $.01444 per unit per day.
Consequently, on the first Record Date (04/01/94), accrued interest will total
$1.1263 per unit for the 78-day period. Because a substantial portion of this
interest will not yet be due from the issuers of the bonds in the Fund, the
first payment to all Unitholders of Record on 04/01/94 is $.3511, and the
remaining $.7752 of accrued interest will remain an asset of the Trust and be
distributed in subsequent periods as portfolio bonds mature, or are redeemed, or
sold and the accrued interest on these bonds is collected. After the first
Record Date daily rates of accrual are:
              Monthly - $0.01444              Quarterly - $0.01453
                             Semi-Annual - $0.01458
This daily rate of accrual, and the annual distributions shown above, will
remain the same as long as the portfolio size and composition remain the same.

  * Record Dates for semi-annual distributions are May 1 and November 1; for quarterly distributions, they are February 1, May 1,
    August 1 and November 1. Record Dates for monthly distributions are the first day of each month.
(1) The first distribution will be paid to all Unitholders, regardless of the distribution plan selected.
(2) The second distribution under the quarterly distribution plan represents a 1-month distribution; subsequent quarterly
    distributions will be regular 3-month distributions.
(3) The second distribution under the semi-annual distribution plan represents a 1-month distribution; subsequent semi-annual
    distributions will be regular 6-month distributions.
</TABLE>
 
+ Interest for Unitholders of this series began to accrue as of the Date of
Deposit. Units purchased on the Date of Deposit will have $.11 of accrued
interest that will be added to the Public Offering Price on the Settlement Date.
After provision for expenses of the Fund, the daily rate of accrual from the
Date of Deposit to the first Record Date is $.01356 per unit per day.
Consequently, on the first Record Date (04/01/94), accrued interest will total
$1.0576 per unit for the 78-day period. Because a substantial portion of this
interest will not yet be due from the issuers of the bonds in the Fund, the
first payment to all Unitholders of Record on 04/01/94 is $.3958, and the
remaining $.6618 of accrued interest will remain an asset of the Trust and be
distributed in subsequent periods as portfolio bonds mature, or are redeemed, or
sold and the accrued interest on these bonds is collected. After the first
Record Date daily rates of accrual are:
              Monthly - $0.01356              Quarterly - $0.01365
                             Semi-Annual - $0.01370
This daily rate of accrual, and the annual distributions shown above, will
remain the same as long as the portfolio size and composition remain the same.

CALL PROTECTION   Bonds are first subject to optional redemption by the issuers
in the years and at the prices shown under the Redemption Provisions column in
the Schedule of Investments. Unless otherwise stated, in subsequent years, bonds
are redeemable at declining prices, but not usually below par value. Some issues
or some portions of issues may also be subject to sinking fund redemption or
extraordinary redemption without premium prior to the dates shown.
 
- -------------------------------------------------
NO CHARGE FOR REDEMPTION   The Trustee, United States Trust Company of New York,
will redeem units at net asset value. In addition, John Nuveen & Co.
Incorporated intends to maintain a secondary market for this Nuveen Tax-Exempt
Unit Trust. Inasmuch as all securities investments are subject to market price
fluctuation, net asset value at the time of redemption could be more or less
than the initial investment.

(1) As of the business day prior to the Date of Deposit. Units are offered at
    the Public Offering Price plus accrued interest.
(2) All figures as of the business day prior to the Date of Deposit. Figures in
    brackets represent the current return. The first year's estimated current
    returns are slightly lower than those for subsequent years because a portion
    of the monies received in the first year only will be treated as a return of
    principal due to the inclusion in the portfolio of "when issued" or other
    Bonds having delivery dates after the date of settlement for a purchase made
    on the Date of Deposit.
(3) In contrast to Estimated Current Return, Estimated Long Term Return reflects
    the amortization of premium or accretion of discount, if any, on the bonds
    in the Trust's portfolio.

  * Record Dates for semi-annual distributions are May 1 and November 1; for quarterly distributions, they are February 1, May 1,
    August 1 and November 1. Record Dates for monthly distributions are the first day of each month.
(1) The first distribution will be paid to all Unitholders, regardless of the distribution plan selected.
(2) The second distribution under the quarterly distribution plan represents a 1-month distribution; subsequent quarterly
    distributions will be regular 3-month distributions.
(3) The second distribution under the semi-annual distribution plan represents a 1-month distribution; subsequent semi-annual
    distributions will be regular 6-month distributions.
</TABLE>
 
+ Interest for Unitholders of this series began to accrue as of the Date of
Deposit. Units purchased on the Date of Deposit will have $.10 of accrued
interest that will be added to the Public Offering Price on the Settlement Date.
After provision for expenses of the Fund, the daily rate of accrual from the
Date of Deposit to the first Record Date is $.01197 per unit per day.
Consequently, on the first Record Date (04/01/94), accrued interest will total
$0.9336 per unit for the 78-day period. Because a substantial portion of this
interest will not yet be due from the issuers of the bonds in the Fund, the
first payment to all Unitholders of Record on 04/01/94 is $.2853, and the
remaining $.6483 of accrued interest will remain an asset of the Trust and be
distributed in subsequent periods as portfolio bonds mature, or are redeemed, or
sold and the accrued interest on these bonds is collected. After the first
Record Date daily rates of accrual are:
              Monthly - $0.01197              Quarterly - $0.01206
                             Semi-Annual - $0.01211
This daily rate of accrual, and the annual distributions shown above, will
remain the same as long as the portfolio size and composition remain the same.

(1) As of the business day prior to the Date of Deposit. Units are offered at
    the Public Offering Price plus accrued interest.
(2) All figures as of the business day prior to the Date of Deposit. Figures in
    brackets represent the current return. The first year's estimated current
    returns are slightly lower than those for subsequent years because a portion
    of the monies received in the first year only will be treated as a return of
    principal due to the inclusion in the portfolio of "when issued" or other
    Bonds having delivery dates after the date of settlement for a purchase made
    on the Date of Deposit.
(3) In contrast to Estimated Current Return, Estimated Long Term Return reflects
    the amortization of premium or accretion of discount, if any, on the bonds
    in the Trust's portfolio.

  * Record Dates for semi-annual distributions are May 1 and November 1; for quarterly distributions, they are February 1, May 1,
    August 1 and November 1. Record Dates for monthly distributions are the first day of each month.
(1) The first distribution will be paid to all Unitholders, regardless of the distribution plan selected.
(2) The second distribution under the quarterly distribution plan represents a 1-month distribution; subsequent quarterly
    distributions will be regular 3-month distributions.
(3) The second distribution under the semi-annual distribution plan represents a 1-month distribution; subsequent semi-annual
    distributions will be regular 6-month distributions.
</TABLE>
 
+ Interest for Unitholders of this series began to accrue as of the Date of
Deposit. Units purchased on the Date of Deposit will have $.11 of accrued
interest that will be added to the Public Offering Price on the Settlement Date.
After provision for expenses of the Fund, the daily rate of accrual from the
Date of Deposit to the first Record Date is $.01378 per unit per day.
Consequently, on the first Record Date (04/01/94), accrued interest will total
$1.0748 per unit for the 78-day period. Because a substantial portion of this
interest will not yet be due from the issuers of the bonds in the Fund, the
first payment to all Unitholders of Record on 04/01/94 is $.4134, and the
remaining $.6614 of accrued interest will remain an asset of the Trust and be
distributed in subsequent periods as portfolio bonds mature, or are redeemed, or
sold and the accrued interest on these bonds is collected. After the first
Record Date daily rates of accrual are:
              Monthly - $0.01378              Quarterly - $0.01387
                             Semi-Annual - $0.01392
This daily rate of accrual, and the annual distributions shown above, will
remain the same as long as the portfolio size and composition remain the same.

AVERAGE PORTFOLIO LIFE   The average maturity of portfolio bonds is 24.5 years.
The first bond is scheduled to mature in October, 2013, with the last bond
maturity being December, 2021.
 
- -------------------------------------------------
 
BONDS INSURED BY MBIA   Each bond in this Nuveen Insured series has been
insured* by the Municipal Bond Investors Assurance Corporation, which guarantees
timely payments of principal and interest. Premium payments have been fully paid
by the Date of Deposit.
 
- -------------------------------------------------
 
CALL PROTECTION   Bonds are first subject to optional redemption by the issuers
in the years and at the prices shown under the Redemption Provisions column in
the Schedule of Investments. Unless otherwise stated, in subsequent years, bonds
are redeemable at declining prices, but not usually below par value. Some issues
or some portions of issues may also be subject to sinking fund redemption or
extraordinary redemption without premium prior to the dates shown.
 
- -------------------------------------------------
 
NO CHARGE FOR REDEMPTION   The Trustee, United States Trust Company of New York,
will redeem units at net asset value. In addition, John Nuveen & Co.
Incorporated intends to maintain a secondary market for this Nuveen Tax-Exempt
Unit Trust. Inasmuch as all securities investments are subject to market price
fluctuation, net asset value at the time of redemption could be more or less
than the initial investment.
 
- -------------------------------------------------
 
REINVESTMENT OPTIONS   Specify automatic reinvestment of trust income, with no
sales charge, to earn compounded dividends with Nuveen mutual funds.
 
- -------------------------------------------------
 
* Insurance relates specifically to the bonds and not to the units or to the
  market value of units. Terms of the insurance are more fully described in the
  prospectus. No representation is made as to the insurer's ability to meet its
  commitments. See Section 5 of the prospectus for details.

  * Record Dates for semi-annual distributions are May 1 and November 1; for quarterly distributions, they are February 1, May 1,
    August 1 and November 1. Record Dates for monthly distributions are the first day of each month.
(1) The first distribution will be paid to all Unitholders, regardless of the distribution plan selected.
(2) The second distribution under the quarterly distribution plan represents a 1-month distribution; subsequent quarterly
    distributions will be regular 3-month distributions.
(3) The second distribution under the semi-annual distribution plan represents a 1-month distribution; subsequent semi-annual
    distributions will be regular 6-month distributions.

+ Interest for Unitholders of this series began to accrue as of the Date of
Deposit. Units purchased on the Date of Deposit will have $.11 of accrued
interest that will be added to the Public Offering Price on the Settlement Date.
After provision for expenses of the Fund, the daily rate of accrual from the
Date of Deposit to the first Record Date is $.01363 per unit per day.
Consequently, on the first Record Date (04/01/94), accrued interest will total
$1.0631 per unit for the 78-day period. Because a substantial portion of this
interest will not yet be due from the issuers of the bonds in the Fund, the
first payment to all Unitholders of Record on 04/01/94 is $.3810, and the
remaining $.6821 of accrued interest will remain an asset of the Trust and be
distributed in subsequent periods as portfolio bonds mature, or are redeemed, or
sold and the accrued interest on these bonds is collected. After the first
Record Date daily rates of accrual are:
              Monthly - $0.01363              Quarterly - $0.01372
                             Semi-Annual - $0.01377
This daily rate of accrual, and the annual distributions shown above, will
remain the same as long as the portfolio size and composition remain the same.

BONDS INSURED BY MBIA   Each bond in this Nuveen Insured series has been
insured* by the Municipal Bond Investors Assurance Corporation, which guarantees
timely payments of principal and interest. Premium payments have been fully paid
by the Date of Deposit.
 
- -------------------------------------------------
 
CALL PROTECTION   Bonds are first subject to optional redemption by the issuers
in the years and at the prices shown under the Redemption Provisions column in
the Schedule of Investments. Unless otherwise stated, in subsequent years, bonds
are redeemable at declining prices, but not usually below par value. Some issues
or some portions of issues may also be subject to sinking fund redemption or
extraordinary redemption without premium prior to the dates shown.
 
- -------------------------------------------------
 
NO CHARGE FOR REDEMPTION   The Trustee, United States Trust Company of New York,
will redeem units at net asset value. In addition, John Nuveen & Co.
Incorporated intends to maintain a secondary market for this Nuveen Tax-Exempt
Unit Trust. Inasmuch as all securities investments are subject to market price
fluctuation, net asset value at the time of redemption could be more or less
than the initial investment.
 
- -------------------------------------------------
 
REINVESTMENT OPTIONS   Specify automatic reinvestment of trust income, with no
sales charge, to earn compounded dividends with Nuveen mutual funds.
 
- -------------------------------------------------
 
* Insurance relates specifically to the bonds and not to the units or to the
  market value of units. Terms of the insurance are more fully described in the
  prospectus. No representation is made as to the insurer's ability to meet its
  commitments. See Section 5 of the prospectus for details.

+ Interest for Unitholders of this series began to accrue as of the Date of
Deposit. Units purchased on the Date of Deposit will have $.11 of accrued
interest that will be added to the Public Offering Price on the Settlement Date.
After provision for expenses of the Fund, the daily rate of accrual from the
Date of Deposit to the first Record Date is $.01329 per unit per day.
Consequently, on the first Record Date (04/01/94), accrued interest will total
$1.0366 per unit for the 78-day period. Because a substantial portion of this
interest will not yet be due from the issuers of the bonds in the Fund, the
first payment to all Unitholders of Record on 04/01/94 is $.3015, and the
remaining $.7351 of accrued interest will remain an asset of the Trust and be
distributed in subsequent periods as portfolio bonds mature, or are redeemed, or
sold and the accrued interest on these bonds is collected. After the first
Record Date daily rates of accrual are:
              Monthly - $0.01329              Quarterly - $0.01338
                             Semi-Annual - $0.01343

This daily rate of accrual, and the annual distributions shown above, will
remain the same as long as the portfolio size and composition remain the same.

BONDS INSURED BY MBIA   Each bond in this Nuveen Insured series has been
insured* by the Municipal Bond Investors Assurance Corporation, which guarantees
timely payments of principal and interest. Premium payments have been fully paid
by the Date of Deposit.
 
- -------------------------------------------------
 
CALL PROTECTION   Bonds are first subject to optional redemption by the issuers
in the years and at the prices shown under the Redemption Provisions column in
the Schedule of Investments. Unless otherwise stated, in subsequent years, bonds
are redeemable at declining prices, but not usually below par value. Some issues
or some portions of issues may also be subject to sinking fund redemption or
extraordinary redemption without premium prior to the dates shown.
 
- -------------------------------------------------
 
NO CHARGE FOR REDEMPTION   The Trustee, United States Trust Company of New York,
will redeem units at net asset value. In addition, John Nuveen & Co.
Incorporated intends to maintain a secondary market for this Nuveen Tax-Exempt
Unit Trust. Inasmuch as all securities investments are subject to market price
fluctuation, net asset value at the time of redemption could be more or less
than the initial investment.
 
- -------------------------------------------------
 
REINVESTMENT OPTIONS   Specify automatic reinvestment of trust income, with no
sales charge, to earn compounded dividends with Nuveen mutual funds.
 
- -------------------------------------------------
 
* Insurance relates specifically to the bonds and not to the units or to the
  market value of units. Terms of the insurance are more fully described in the
  prospectus. No representation is made as to the insurer's ability to meet its
  commitments. See Section 5 of the prospectus for details.
