                            THE MUNICIPAL BOND TRUST
                                   SERIES 230
  This   Prospectus   consists   of   two  parts.  Part  A  contains  Essential
  Information   Regarding  the  Trust  including  descriptive  material  relat-
  ing  to  the  Trust,  Financial  Statements  of  the  Trust,  and  a Schedule
  of  Investments.  Part  B  contains  general  information  about  the  Trust.
  Part A may not be distributed unless accompanied by Part B.
  Interest   income   to   the   Trust  and  to  Certificateholders  is   7,673
  excludable,   in   the   opinion   of   counsel,  from  gross  income   UNITS
  for   Federal   income   tax   purposes   under   existing  law,  but
  may  be  subject  to  state  and  local  taxation.  Capital gains, if
  any, are subject to tax.
  THE    INITIAL    PUBLIC    OFFERING    OF    UNITS    IN   THE   TRUST   HAS
  BEEN     COMPLETED.     THE     UNITS     OFFERED     HEREBY    ARE    ISSUED
  AND    OUTSTANDING    UNITS    WHICH    HAVE    BEEN    ACQUIRED    BY    THE
  SPONSOR     EITHER    BY    PURCHASE    FROM    THE    TRUSTEE    OF    UNITS
  TENDERED FOR REDEMPTION OR IN THE SECONDARY MARKET.
       THE     OBJECTIVES    OF    THE    MUNICIPAL    BOND    TRUST,    SERIES
       230   -The   Municipal  Bond  Trust,  Series  230  (the  "Trust")  is  a
       unit   investment   trust   formed  for  the  purpose  of  gaining  Fed-
       erally   tax-exempt   interest  income  consistent  with  the  preserva-
       tion  of  capital  and  diversification  of  risk  through investment in
       a   fixed   portfolio   of   "investment  grade"  (as  of  the  Date  of
       Deposit)   interest-bearing   municipal   bonds   (the   "Bonds").   The
       payment   of   interest  and  the  preservation  of  capital  is  depen-
       dent   upon   the  continuing  ability  of  the  respective  issuers  of
       such    Bonds    to    meet   their   obligations.   Since   PaineWebber
       Incorporated    (the    "Sponsor")    and   Investors   Bank   &   Trust
       Company   and   The   First   National   Bank   of   Chicago,   as   Co-
       Trustees   (the   "Co-Trustees")   do   not   have   control   over  the
       source   of   payment   of   the   Bonds,  they  cannot  guarantee  that
       the  objectives  of  the  Trust  will  be  achieved.  Each  Unit  at the
       date  hereof  represents  1/7,673rd  fractional  undivided  interest  in
       the   $7,660,000   principal   amount   of   bonds  and  net  income  of
       the  Trust  in  the  ratio  of  1  Unit  for  each  $998.31 par value of
       Bonds  in  the  Trust.  (See  "Nature  of  the  Trust"  in  Part B). The
       aggregate   market   value,  based  on  the  bid  side  of  the  market,
       of   the   Bonds   in   the   Trust   was,   as   of   April  30,  1994,
       $8,045,097.
       PUBLIC   OFFERING   PRICE-The   Public   Offering   Price  of  Units  is
       equal   to   the   aggregate   of  the  bid  prices  of  the  underlying
       Bonds   divided  by  the  number  of  Units  outstanding  plus  a  sales
       charge   of   up   to  5.82%  of  the  net  amount  invested  (5.50%  of
 <PAGE>
       the   Public   Offering   Price).   Units  are  offered  at  the  Public
       Offering  Price  plus  accrued  interest.  (See  "Public  Offering Price
       of Units" and "Secondary Market for Units" in Part B).
       MARKET    FOR   UNITS-Although   under   no   obligation   to   do   so,
       the   Sponsor   intends  to  maintain  a  market  for  Units  at  prices
       based  on  the  aggregate  bid  price  of  the  Bonds  in  the Trust. If
       such   market   is  terminated,  a  Certificateholder  may  be  able  to
       dispose   of   his   Units  only  through  redemption.  (See  "Secondary
       Market for Units" in Part B).
       DISTRIBUTIONS-Distributions   of   interest   received   by  the  Trust,
       less  expenses,  will  be  made  on  a  monthly  basis.  Distribution of
       principal,   if   any,   will   be   made   on  a  semi-annual  or  more
       frequent   basis.  See  "Distribution  to  Certificateholders"  in  Part
       B for details of optional distributions.
       ESTIMATED     CURRENT     RETURN-The     Estimated     Current    Return
       per   Unit   is   determined   by   dividing  the  net  annual  interest
       income   per   Unit   by   the  Public  Offering  Price  per  Unit.  Any
       change   in   either  amount  will  result  in  a  change  in  Estimated
       Current   Return.   (See   "Estimated   Current   Return  per  Unit"  in
       Part B and "Essential Information" in Part A).
  THESE     SECURITIES     HAVE     NOT     BEEN     APPROVED     OR     DISAP-

  REPRESENTATION TO THE CONTRARY IS A CRIMINAL OFFENSE.

  ESSENTIAL INFORMATION REGARDING THE TRUST
  Securities in the Trust Portfolio
       The   Trust   consists  of  the  Securities  indicated  under  "Schedule
  of   Investments",   all   undistributed  interest  received  or  accrued  on
  the   Securities,   and  any  undistributed  cash  realized  from  the  sale,
  redemption  or  other  disposition  of  the  Securities.  The Trust portfolio
  consists  of  16  issues  of  Bonds  by  issuers  located  in 9 states of the
  United  States  and  the  District  of  Columbia.  All  of  the  Bonds in the
  Trust  were,  as  of  the  Date  of  Deposit,  "investment  grade"  municipal
  bonds.
       On  April  30,  1994,  the  aggregate  market  value  of  the Securities
  in the Trust, based on the bid side of the market, was $8,045,097.
       All   sixteen   issues   of   Bonds  in  the  Trust  are  revenue  bonds
  payable   from   revenues  derived  by  the  issuers,  and  while  income  to
  pay   such   Bonds   may   be   derived   from  more  than  one  source,  the
  primary   source  of  such  income,  along  with  the  number  of  issues  of
  the  Trust  portfolio  deriving  income  from  such  source  are  as follows:
  3   Electric  and  Power  facilities;  1  Health  and  Hospital  facility;  2
  Universities;   1   Resource  Recovery  facility;  8  Refunded  Bonds  and  1
  Housing   facility.  The  Trust  may  be  considered  "concentrated"  in  the
  following categories of Bonds:
                                                           Percentage of
                                                             Aggregate
                                                            Market Value

       See   "Summary   of  Portfolio"  contained  in  Part  B  for  a  summary
  of   the  Investment  risks  associated  with  the  Securities  contained  in
  the Trust.
  Ratings-
       On  the  Date  of  Deposit,  all  of  the  Bonds  were  rated  a minimum
  of    A   by   Standard   &   Poor's   Corporation   or   Moody's   Investors
  Service,   Inc.   The   ratings   may   have  changed  and  may  continue  to
  change  after  the  Date  of  Deposit.  On  April  30,  1994,  the percentage
  of  the  total  aggregate  market  value  of  bonds  in the portfolio in each
  rating   category   was   as   follows:  AAA,  30%;  AA,  14%;  A,  30%;  Aaa
  (Moody's),   18%   and   Aa   (Moody's),   8%.   (See   "Summary  of  Portfo-
  lio"   and   "Bond   Ratings"   in  Part  B  and  "Schedule  of  Investments"
  in Part A).
       See   "Summary   of  Portfolio"  contained  in  Part  B  for  a  summary
  of   investment  risks  associated  with  the  Securities  contained  in  the
  Trust.
     
  Tax Status of the Trust-
       At  the  time  of  issuance  of  the  Securities, opinions regarding the
  validity   of   such   Securities  and  the  exemption  from  federal  income
  tax  of  interest  on  such  Securities  were  rendered  by  bond  counsel to
                                        1
 <PAGE>
  the  respective  issuers.  Except  in  certain  instances  in  which  Orrick,
  Herrington   &  Sutcliffe  acted  as  bond  counsel  to  issuers  of  Securi-
  ties,  neither  the  Sponsor,  the  Co-Trustees,  nor  counsel  to either has
  made  any  review  of  the  proceedings  relating  to  the  issuance  of  the
  Securities   or  the  basis  for  such  opinions.  In  the  case  of  certain
  Securities  in  the  Trust,  the  opinions  of  bond  counsel  indicate  that
  interest  on  such  obligations  received  by  a  "substantial  user"  of the
  facilities   being  financed  with  the  proceeds  of  such  obligations,  or
  "related   person,"   for   periods   such   obligations  are  held  by  such
  "substantial   user"   or   "related   person,"   will  not  be  exempt  from
  federal   income   tax.  Interest  income  attributable  to  such  Securities
  received   by   a   Unitholder  who  is  a  "substantial  user"  or  "related
  person" may be taxable to such Unitholder.
       In  the  opinion  of  Orrick,  Herrington  &  Sutcliffe,  counsel to the
  Sponsor, under existing law:
       1.  The  Trust  is  not  an  association  taxable  as  a corporation for
  Federal   income   tax   purposes.   Under   the  Internal  Revenue  Code  of
  1986,   as   amended   (the   "Code"),   each  holder  of  a  certificate  of
  ownership  (a  "Certificateholder")  will  be  treated  as  the  owner  of  a
  pro  rata  portion  of  the  Trust,  and  income of the Trust will be treated
  as   income   of  the  Certificateholders.  Interest  on  Securities  in  the
  Trust   that   is  excludable  from  gross  income  for  federal  income  tax
  purposes   when   received   by   the   Trust   will  retain  its  status  as
  excludable   when   distributed   to   Certificateholders,   except  that  no
  opinion   is   expressed   regarding   the   character  of  interest  on  any
  Security   in   the   case   of  any  Certificateholder  who  is  a  "related
  person"   or   a   "substantial  user",  both  as  defined  in  Code  Section
  147(a).
       2.   Each   Certificateholder   will  have  a  taxable  event  when  the
  Trust   disposes   of   a   Security  (whether  by  sale,  exchange,  redemp-
  tion,  or  payment  at  maturity),  or  when  the  Certificateholder  redeems
  or  sells  its  Certificates.  For  purposes  of  determining  gain  or loss,
  the  total  tax  cost  of  each  Unit  to  a  Certificateholder  is allocated
  among   each   of  the  Securities  in  accordance  with  the  proportion  of
  the   Trust   comprised   by   each   Security,   to   determine   the   Cer-
  tificateholder's  per  Unit  tax  cost  for  each  Security. Further, the tax
  cost   reduction  requirements  of  the  Code  relating  to  amortization  of
  bond  premium  will  apply  separately  to  the  per  Unit  tax  cost of each
  Security.
       3.  The  Trust  is  not  an  association  taxable  as  a corporation for
  New   York   State   income   tax   purposes.   Under  New  York  State  law,
  each   Certificateholder  will  be  treated  as  the  owner  of  a  pro  rata
  portion   of  the  Trust,  and  income  of  the  Trust  will  be  treated  as
  income  of  the  Certificateholders.  Interest  on  Securities  in  the Trust
  that   is   exempt  from  personal  income  tax  under  New  York  State  law
  when   received   by  the  Trust  will  retain  its  tax-exempt  status  when
  distributed to Certificateholders.
  Additional Tax Considerations-
       Recognition  of  Gain.  The  Code,  by  virtue  of  the  Tax  Reform Act
  of  1986,  effects  a  substantial  reduction  in  the  number  of income tax
                                        2
 <PAGE>
  brackets   and   rate   levels  for  individuals  and  corporations  and  ad-
  versely   modifies   the   preferential   treatment  accorded  the  net  gain
  from   the  sale  or  exchange  of  capital  assets.  The  maximum  rate  for
  net  capital  gain  of  individuals  in  1987  is limited to 28%. Net capital
  gain   recognized  by  corporations  after  1986  and  by  individuals  after
  1987   will   be   taxed  at  the  same  tax  rates  applicable  to  ordinary
  income.
       As  a  result  of  the  tax  cost  reduction  requirements  of  the Code
  relating   to   amortization   of   bond   premium,   under  certain  circum-
  stances   Unitholders   may  realize  a  taxable  gain  upon  disposition  of
  Units   even   though   such  Units  are  sold  or  redeemed  for  an  amount
  equal to or less than their original cost.
       Original   Issue   Discount  and  Market  Discount.  The  portfolio  may
  contain   Securities   originally  issued  at  a  discount  ("original  issue
  discount").   In   general,   original  issue  discount  is  defined  as  the
  difference   between   the   price   at  which  a  bond  is  issued  and  its
  stated   redemption   price   at   maturity.   With   respect  to  tax-exempt
  obligations   issued   on   or  before  September  3,  1982,  original  issue
  discount   is   deemed   to  accrue  (be  "earned")  as  tax-exempt  interest
  ratably  over  the  life  of  the  obligations  and  is apportioned among the
  original   holder   of   the   obligation   and   subsequent   purchasers  in
  accordance   with   a   ratio  the  numerator  of  which  is  the  number  of
  calendar   days   the   obligation   is   owned   by   the   holder  and  the
  denominator  of  which  is  the  total  number  of  calendar  days  from  the
  date  of  issuance  of  the  obligation  to  its  maturity date. With respect
  to   tax-exempt   obligations   issued  after  September  3,  1982,  original
  issue   discount   is   deemed   earned   in  a  geometric  progression  over
  the   life   of   the   obligations,  taking  into  account  the  semi-annual
  compounding   of   accrued   interest,  resulting  in  an  increasing  amount
  of interest in each year.
       In  general,  if  a  Unitholder  acquires  a  pro  rata  interest  in  a
  Security  for  a  price  that  is  less  than  its stated redemption price at
  maturity  (or  less  than  the  original  issue  price  plus accrued original
  issue   discount,   if   such   Security   was  issued  with  original  issue
  discount),   such   pro   rata  interest  will  be  treated  as  having  been
  purchased  at  a  "market  discount".  If  gain  is  realized  upon  the sale
  or  other  disposition  of  such  pro  rata  interest,  the  market  discount
  will   constitute  taxable  gain.  Such  gain  generally  will  be  long-term
  capital   gain   to   Unitholders,  other  than  dealers  in  securities  and
  certain  financial  institutions,  if  the  Securities  are held by the Trust
  for   more   than   six   months   and   such  Unitholders  have  held  their
  Units for more than one year.
       Interest   on   Borrowed   Funds.   Interest   paid  on  funds  borrowed
  to  purchase  or  carry  units  of  a  unit investment trust that distributes
  tax-exempt   interest   income   during   a   tax  year  is  not  deductible.
  Under   rules   of   the   Internal  Revenue  Service  for  determining  when
  borrowed   funds   are   considered   used  for  the  purpose  of  purchasing
  or  carrying  particular  assets,  the  purchase  of  Units  may  be  consid-
  ered   to   have   been   made   with   borrowed   funds   even   though  the
  borrowed funds are not directly traceable to the purchase of Units.
       Social   Security   Benefits.   Code   Section   86   provides   that  a
                                        3
 <PAGE>
  portion  of  social  security  benefits  received  after  December  31, 1983,
  are   includible   in   taxable   income   for   taxpayers   whose  "modified
  adjusted   gross   income",  combined  with  50%  of  their  social  security
  benefits,   exceeds   a   base   amount.  The  base  amount  is  $25,000  for
  an  individual,  $32,000  for  a  married  couple  filing a joint return, and
  zero  for  married  persons  filing  seperate  returns.  Under  Code  Section
  86,   interest  on  tax-exempt  bonds  is  to  be  added  to  adjusted  gross
  income   for   purposes   of   determining  whether  an  individual's  income
  exceeds   the   base   amount   above   which   a  portion  of  the  benefits
  would  be  subject  to  tax.  The  amount  of  social  security benefits that
  could   be   includible   in   taxable   income   would   be  the  lesser  of
  one-half  of  the  benefits  or  one-half  of  the  excess  of the taxpayer's
  combined   income   (modified   adjusted   gross   income  plus  one-half  of
  benefits) over the base amount.
       Tax   Reform   Act   of   1986--Effects   on  Tax-Exempt  Interest.  The
  Tax   Reform   Act   of   1986,   among   other   items,   provided  for  the
  following:   (1)   Effective  for  taxable  years  beginning  after  December
  31,1986,   the   alternative   minimum   tax  rate  for  individuals  is  in-
  creased   to  21%,  and  the  interest  on  certain  Private  Activity  Bonds
  issued   after  August  7,  1986  is  included  in  the  calculation  of  the
  individual   alternative   minumum   tax.   Each   Security   in   the  Trust
  received  or  will  receive  an  opinion  of  bond counsel to the effect that
  it  is  not  a  Private  Activity  Bond  the  interest on which is subject to
  the   alternative  minimum  tax.  (2)  Effective  for  taxable  years  begin-
  ning   after  December  31,  1986,  the  alternative  minimum  tax  rate  for
  corporations   is   increased   from   15%   to  20%,  and  for  purposes  of
  this   tax,   interest   on  certain  Private  Activity  Bonds  issued  after
  August  7,  1986,  and  50%  of  the  excess  of  a  corporation's  net  book
  income    (adjusted)    over   its   alternative   minimum   taxable   income
  (adjusted)   are   classified  as  tax  preference  items.  Net  book  income
  includes  interest  on  all  tax-exempt  bonds,  such  as  the Securities. In
  taxable   years   beginning   after  1989,  the  use  of  adjusted  net  book
  income   in   determining   such   alternative   minimum   tax   is   to   be
  replaced   by   the  use  of  adjusted  current  earnings,  and  75%  of  the
  amount   by   which   adjusted  current  earnings  exceed  alternative  mini-
  mum   taxable   income,   as   modified   for   this   calculation,  will  be
  included   in   alternative   minimum   taxable   income.   Interest  on  the
  Securities   is   includible   in  the  adjusted  net  book  income  and  ad-
  justed   current   earnings   of   a   corporation   for   purposes  of  such
  alternative   minimum   tax.   The   Tax   Reform   Act   of  1986  does  not
  otherwise   require  corporations,  and  does  not  require  taxpayers  other
  than   corporations,   including   individuals,  to  treat  interest  on  the
  Securities  as  an  item  of  tax  preference  in  computing  and alternative
  minimum  tax.  (3)  Subject  to  certain  exceptions,  financial institutions
  may   not   deduct   that  portion  of  the  institution's  interest  expense
  allocable   to   tax-exempt  interest  on  tax-exempt  bonds  acquired  after
  August   7,   1986.   (4)   The   amount   of   the   deduction   allowed  to
  property   and   casualty   insurance  companies  for  underwriting  loss  is
  decreased    by    an   amount   determined   with   regard   to   tax-exempt
  interest   income  and  the  deductible  portion  of  dividends  received  by
  such   companies,   effective   for  taxable  years  beginning  after  Decem-
                                        4
 <PAGE>
  ber  31,  1986.  (5)  All  taxpayers  are  required  to  report  for informa-
  tional   purposes   on  their  federal  income  tax  returns  the  amount  of
  tax-exempt   interest  they  receive,  effective  for  taxable  years  begin-
  ning   after   December   31,   1986.   (6)   An  issuer  must  meet  certain
  requirements   on   a   continuing   basis   in   order  for  interest  on  a
  tax-exempt   bond   to   be   tax  exempt;  failure  to  meet  such  require-
  ments   results   in   loss   of   tax   exemption.  (7)  For  taxable  years
  beginning   after  December  31,  1986,  a  branch  profits  tax  is  imposed
  on   the  U.S.  branches  of  foreign  corporations  which,  because  of  the
  manner  in  which  the  branch  profits  tax  is  calculated,  may  have  the
  effect   of   subjecting   the  U.S.  branch  of  a  foreign  corporation  to
  federal   income   tax  on  the  interest  on  bonds  otherwise  exempt  from
  such tax.
       The   Tax   Reform   Act   of   1986   also  significantly  curtailed  a
  taxpayer's   ability   to  offset  income  with  deductions  and  losses.  In
  general,   a   lower   overall  rate  of  income  taxation  could  make  tax-
  exempt   bonds   less   attractive   to  investors  and  could  decrease  the
  value  of  tax-exempt  Securities  held  by  the  Trust,  while  the  limita-
  tions  on  the  ability  to  offset  taxable  income  may  have  the opposite
  effect.   In   addition,   certain  "S  Corporations"  may  have  a  tax  im-
  posed   on   passive   income   including   tax-exempt   interest,   such  as
  interest on the Securities.
       Alternative  Minimum  Tax.  Interest  on  the  Securities  in  the Trust
  is  not  treated  as  a  preference  item  for  purposes  of  calculating the
  individual   and   corporate  alternative  minimum  tax.  However,  the  Code
  provides   that   for   taxable   years   1988   and   1989,   50%  (75%  for
  taxable  years  beginning  after  1989)  of  the  excess  of  a corporation's
  adjusted   net   book   income   over   its   adjusted   alternative  minimum
  taxable  income  will  be  treated  as  a  preference  item  in  the calcula-
  tion   of   alternative   minimum   taxable   income.   For   taxable   years
  beginning   after  1989,  the  use  of  adjusted  net  book  income  will  be
  replaced   by  the  use  of  adjusted  current  earnings.  The  adjusted  net
  book   income   and  adjusted  current  earnings  of  a  corporation  include
  the   amount   of   any   income  received  that  is  otherwise  exempt  from
  tax, such as interest on the Securities.
       Superfund   Revenue   Act   of   1986.  The  Superfund  Revenue  Act  of
  1986   (the   "Superfund   Act")   imposed   a  deductible,  broad-based  tax
  on   a   corporation's   alternative   minimum  taxable  income  (before  net
  operating  losses  and  any  deduction  for  the  tax)  at  a rate of $12 per
  $7,250   (0.12%)   of   alternative  minimum  taxable  income  in  excess  of
  $2,000,000.   The   tax  is  imposed  for  tax  years  beginning  after  1986
  and  beginning  before  1992.  The  tax  is  imposed  even  if  the  corpora-
  tion   pays   no   alternative  minimum  tax.  For  purposes  of  the  Super-
  fund   Act,   alternative   minimum   taxable  income  includes  interest  on
  all   tax-exempt   bonds   to   the  same  extent  and  in  the  same  manner
  as   does   the   Tax  Reform  Act  of  1986.  The  Superfund  Act  does  not
  impose   an   alternative  minimum  tax  on  taxpayers  other  than  corpora-
  tions.
       Branch   Profits   Tax.  The  Code  provides  that  interest  on  exempt
  obligations   such   as  the  Securities  is  included  in  effectively  con-
  nected   earnings   and   profits   for  purposes  of  computing  the  branch
                                        5
 <PAGE>
  profits   tax   on   certain  foreign  corporations  doing  business  in  the
  United States.
       Property    and   Casualty   Companies.   The   Code   contains   provi-
  sions   relating   to   property   and   casualty  companies  whereunder  the
  amount   of   certain  loss  deductions  otherwise  allowed  is  reduced  (in
  certain  cases  below  zero)  by  a  specified  percentage  of,  among  other
  things,   interest   on  tax-exempt  obligations  acquired  after  August  7,
  1986.
       Financial    Institutions.    The    Code   provides   that   commercial
  banks,   thrift   institutions  and  other  financial  institutions  may  not
  deduct  the  portion  of  their  interest  expense  allocable  to  tax-exempt
  obligations   after   August   7,   1986   (other  than  certain  "qualified"
  obligations). The Securities are not qualified for this purpose.
       S   Corporations.   The  Code  imposes  a  tax  on  excess  net  passive
  income   of   certain   S   corporations  that  have  subchapter  C  earnings
  and   profits.   Passive   investment   income   includes  interest  on  tax-
  exempt obligations.
       Information   Reporting.  All  taxpayers  are  required  to  report  for
  informational   purposes   on   their   federal   income   tax   returns  the
  amount of tax-exempt interest they receive.
       Future   Legislation.Various   proposals   have   been   introduced  be-
  fore  Congress  from  time  to  time  to  restrict  or  eliminate the federal
  income   tax   exemption   for  interest  on  municipal  securities  such  as
  those   deposited   in  the  Trust.  Such  proposals  may  be  introduced  in
  the  future.  The  Sponsor  cannot  predict  what  additional legislation, if
  any,   may   be   proposed   with   respect   to  the  tax-exempt  status  of
  interest   on   municipal   securities,   nor  can  it  predict  whether  any
  legislation, if enacted, would apply to Securities in the Trust.
       State   Tax.   The   exemption   from   gross   income  of  interest  on
  municipal   bonds   for   federal   income   tax   purposes   does  not  nec-
  essarily   result   in  an  exemption  under  the  income  tax  laws  of  any
  state  or  local  government.  The  laws  of  the  several  states  vary with
  respect   to   the   taxation   of   municipal  bonds,  and  Unitholders  are
  advised to consult with their tax advisors regarding such taxation.

   THE UNITHOLDERS, SPONSOR AND CO-TRUSTEES
   THE MUNICIPAL BOND TRUST, SERIES 230:
       We  have  audited  the  accompanying  statement  of  financial  condition,  including  the  schedule of investments, of
   The  Municipal  Bond  Trust,  Series  230  as  of  April  30,  1994  and the related statements of operations and changes in
   net  assets  for  each  of  the  two  years  in  the  period ended April 30, 1994 and for the period from May 17, 1991 (date
   of  deposit)  to  May  1,  1992. These financial statements are the responsibility of the Co-Trustees. Our responsibility is
   to express an opinion on these financial statements based on our audits.
       We  conducted  our  audits  in  accordance  with  generally  accepted  auditing standards. Those standards require that
   we  plan  and  perform  the  audit  to  obtain  reasonable  assurance  about  whether  the  financial statements are free of
   material   misstatement.   An   audit   includes   examining,   on  a  test  basis,  evidence  supporting  the  amounts  and
   disclosures  in  the  financial  statements.  Our  procedures  included confirmation of the securities owned as of April 30,
   1994  as  shown  in  the  statement  of  financial  condition  and  schedule  of  investments  by  correspondence  with  the
   Co-Trustees.  An  audit  also  includes  assessing  the  accounting  principles  used  and significant estimates made by the
   Co-Trustees,  as  well  as  evaluating  the  overall  financial statement presentation. We believe that our audits provide a
   reasonable basis for our opinion.
       In  our  opinion,  the  financial  statements referred to above present fairly, in all material respects, the financial
   position  of  The  Municipal  Bond  Trust,  Series  230  at  April 30, 1994 and the results of its operations and changes in
   its  net  assets  for  each  of  the  two  years  in  the  period  ended April 30, 1994 and for the period from May 17, 1991
   (date of deposit) to May 1, 1992, in conformity with generally accepted accounting principles.

                               NATURE OF THE TRUST
       Each   series   of   The   Municipal   Bond  Trust  is  a  separate  but
  similar   unit   investment  trust,  formed  for  the  purpose  of  obtaining
  federally   tax-exempt  interest  income  consistent  with  the  preservation
  of  capital  and  diversification  of  risk  through  investment  in  a fixed
  portfolio   comprised   of   "investment   grade"   (as   of   the   Date  of
  Deposit)   interest-bearing   Bonds.   State   Trusts  were  formed  for  the
  additional   purpose   of   obtaining   interest  income  exempt  from  state
  income   taxes   for  purchasers  who  qualify  as  residents  of  the  state
  for   which   each   such  Trust  is  named.  The  Sponsor  and  the  Trustee
  do  not  have  control  over  the  course  of  payment  of  the  principal of
  and  interest  on  the  Securities,  therefore  they  cannot  guarantee  that
  the   objectives  of  the  Trust  will  be  achieved.  The  interest  on  the
  Bonds,  in  the  opinion  of  counsel  to  the  issuers  of  such  Bonds, is,
  or   upon   their   issuance  and  delivery  will  be,  exempt  from  present
  Federal   income   taxes.   Capital   gains,  if  any,  will  be  subject  to
  taxation.
       The  portfolio  of  the  Trust  consists of interest-bearing Securities,
  issued  by  or  on  behalf  of  states,  counties  and  municipalities within
  the  United  States,  and  authorities,  agencies  and  other  such political
  subdivisions.
                              CREATION OF THE TRUST
       The  Trust  was  created  under  the  laws  of  the  State  of  New York
  pursuant   to   a   Trust   Indenture   and   Agreement*  (the  "Indenture"),
  dated   as   of   the   Date  of  Deposit,  among  PaineWebber  Incorporated,
  as  Sponsor,  the  Trustee  identified  in  Part  A  of  this  prospectus and
  Kenny Information Systems, Inc. as Evaluator.
       On  the  Date  of  Deposit,  the  Sponsor  deposited  with  the  Trustee
  the  Securities  or  confirmations  of  contracts  for  the  purchase  of the
  Securities   at   prices   determined  by  the  Evaluator  on  the  basis  of
  current  offering  prices  of  the  Securities.  Confirmations  of  contracts
  for   the   purchase   of   the   Bonds   were   delivered   to  the  Trustee
  together  with  an  irrevocable  letter  of  credit  drawn  on  a  commercial
  bank   in   an   amount   sufficient   for   their  purchase.  Following  the
  deposit,  the  Trustee  delivered  to  the  Sponsor  registered  Certificates
  for   Units   evidencing  the  entire  ownership  of  the  Trust.  Each  Unit
  represents  a  fractional  undivided  interest  in  the  Trust  in  an amount
  equal   to  one  divided  by  the  total  number  of  Units  outstanding.  On
  the   Date   of   Deposit   there   was   one   Unit  for  each  $1,000  face
  amount of Securities deposited in the Trust.
                              SUMMARY OF PORTFOLIO
       An   investment   in   Units  of  the  Trust  should  be  made  with  an
  understanding   of  the  risks  which  an  investment  in  fixed  rate  long-
 <PAGE>
  term  debt  obligations  may  entail,  including  the  risk that the value of
  the  Trust  portfolio  and  hence  of  the  Units will decline with increases
  in  interest  rates.  The  recent  period  of  high  inflation, together with
  the   fiscal   measures  adopted  to  attempt  to  deal  with  it,  has  seen
  wide  fluctuations  in  interest  rates  and  thus in the value of fixed rate
  long-term   debt   obligations   generally.   The   Sponsor   cannot  predict
  whether such fluctuations will continue in the future.
       As   set   forth   under   "Essential   Information"  and  "Schedule  of
  Investments"  in  Part  A,  the  Trust  may  contain  or  be  concentrated in
  one  or  more  of  the  categories  of  Securities  referred  to  below.  The
  types   of   issuers   and   percentages   of  any  concentrations  for  this
  Trust  are  set  forth  in  Part  A.  These  categories are described in Part
  B  because  an  investment  in  Units  of  the  Trust  should  be  made  with
  an   understanding   of   the  risks  which  these  investments  may  entail.
  Part B also contains a description of the features of this Trust.
  General Obligation Bonds
       General  obligation  debt  of  an  issuer  that  is a political subdivi-
  sion  or  instrumentality  of  a state is typically secured by the full faith
  and   credit   of   the   issuer,   encompassing   its  ability  to  levy  an
  unlimited  ad  valorem  tax  on  real  property  or  other  revenue  streams,
  such   as   sales  or  income  taxes.  The  fiscal  condition  of  an  issuer
  may    be   affected   by   socioeconomic   factors   beyond   the   issuer's
  control   (such   as   relocation   by  a  major  employer)  or  other  unan-
  ticipated   events,   including:   imposition   of   tax  rate  decreases  or
  appropriations  limitations  by  legislation  or  initiative;  increased  ex-
  penditures   mandated  by  Federal  or  state  law  or  by  judicial  decree;
  reduction  of  unrestricted  federal  or  state  aid  and  of revenue-sharing
  programs   due   to   subsequent   legislative   changes   in  appropriations
  or   aid   formulas;  or  disallowances  by  the  Federal  or  state  govern-
  ments  for  categorical  grants.  The  fiscal  condition  of  an  issuer that
  is  a  political  subdivision  or  instrumentality  of  a  state  (such  as a
  county,  city,  school  district  or  other entity providing public services)
  is  related  to  the  size  and  diversification  of its tax and revenue base
  and  to  such  other  factors  as:  the  effect  of  inflation on the general
  operating   budget   and  of  other  costs,  including  salaries  and  fringe
  benefits,  energy  and  solid  waste  disposal;  changes  in  state  law  and
  statutory    interpretations   affecting   traditional   home   rule   powers
  (which  vary  from  state  to  state);  levels  of  unrestricted state aid or
  revenue-sharing   programs   and   state   categorical   grants   subject  to
  annual   appropriation   by   a  state  legislature;  increased  expenditures
  mandated   by   state   law   or   judicial  decree;  and  disallowances  for
  expenses   incurred   under   Federal   or   state   categorical  grant  pro-
  grams.
       *Reference   is   hereby   made  to  said  Trust  Indenture  and  Agree-
  ment   and   any   statements   contained   herein  are  qualified  in  their
  entirety by the provisions of said Trust Indenture and Agreement.
  The   local   economy   may  be  or  become  concentrated  (i)  in  a  single
  industry,  which  may  be  affected  by  natural  or  other  disasters  or by
 <PAGE>
  fluctuations  in  commodity  prices,  or  (ii)  in  a particular company, the
  operations   of   which   may   be   impaired  due  to  labor  disputes,  re-
  location,   bankruptcy   or   corporate   take-over.  Such  economic  factors
  may,  in  turn,  affect  local  tax  collections  and  service  demands.  The
  ability  of  an  issuer  to  levy  additional  taxes  may be subject to state
  constitutional   provisions,   assent  of  the  state  legislature  or  voter
  approval   in   a   local   referendum,   or   constrained   by  economic  or
  political considerations.
  Housing Facility Securities
       These   Securities   are   typically   secured   by   mortgage  revenues
  derived    by    state    housing   finance   agencies,   municipal   housing
  authorities   or   certain   non-profit   organizations  from  repayments  on
  mortgage    and    home    improvement   loans   made   by   such   entities.
  Special   considerations  affecting  housing  securities  include:  the  con-
  dition   of   the   local   housing  market,  competition  from  conventional
  mortgage  lenders,  fluctuations  in  interest  rates,  increasing  construc-
  tion   costs   and  the  ability  of  the  Issuers,  lenders,  servicers  and
  borrowers   to   maintain   program   compliance   under   applicable  statu-
  tory   provisions.  Securities  issued  on  or  before  April  24,  1979  are
  subject   to   few   restrictions   on  the  use  of  proceeds.  Federal  tax
  legislation   adopted   during   the   1980s   imposed   progressively   more
  restrictive   requirements   for   post-issuance   compliance   necessary  to
  maintain   the   tax   exemption  on  both  single  family  and  multi-family
  housing  securities.  IRS  regulations  provide,  however,  that  retroactive
  taxation   will   not   occur   if  the  issuer  corrects  any  noncompliance
  occurring  after  the  issuance  of  a  security  within  a reasonable period
  after   such   noncompliance   is   first  discovered  or  should  have  been
  discovered   by  the  issuer.  To  maintain  the  security's  tax  exemption,
  the   issuer  may  be  required  pursuant  to  the  legal  documents  govern-
  ing  the  Security  to  redeem  all  or  a  portion  of  such  obligations at
  par   from   (i)   unexpended   proceeds   of   the  issue  within  a  stated
  period  that  typically  does  not  exceed  three  years  from  the  date  of
  issuance   of   such   security   or   (ii)  optional  prepayments  by  mort-
  gagors.  If  the  issuers  of  such  securities  are  unable to or choose not
  to   reloan   these  monies,  they  will  generally  redeem  such  securities
  at    par   in   an   amount   approximately   equal   to   such   unexpended
  proceeds   or   prepayments.   The  Sponsor  is  unable  to  predict  whether
  such   redemptions   will  occur,  or  what  effect,  if  any,  such  redemp-
  tions would have on any such Securities in the Trust.
  Single Family Housing Securities.
       Securites   issued  after  April  24,  1979  and  prior  to  August  15,
  1986  are  subject  to  the  requirements  of  Section  103A  of the Internal
  Revenue   Code   of   1954,   as   amended  (the  "1954  Code").  Enacted  in
  1980    and   subsequently   amended,   Section   103A   established   strin-
  gent   criteria   for   the  origination  or  assumption  of  mortgage  loans
  and   subjected   Issuers   to   annual   IRS   reporting  requirements.  The
  Technical   and   Miscellaneous   Revenue   Act   of  1988  may  inhibit  the
  ability   of   Issuers  to  make  home  mortgage  loans  after  December  31,
  1990   (and   thereby   increase   the   likelihood   of   redemptions   from
 <PAGE>
  unexpended   proceeds).   Additional   considerations   include:  the  under-
  writing  and  management  ability  of  the  issuers,  lenders  and  servicers
  (i.e.,   the  initial  soundness  of  the  loan  and  the  effective  use  of
  available  remedies  should  there  be  a  default  in  loan  payments);  the
  financial  condition  and  credit  rating  of  the  private  mortgage insurer
  underwriting   the   insurance   on   the  underlying  mortgage  or  pool  of
  mortgages;   and   special   risks   attendant   to  lending  to  mortgagors,
  most   of   whom   are   first   time   home   buyers   of  low  or  moderate
  means.
       During   periods   of   declining  interest  rates,  there  may  be  in-
  creased   redemptions   of   single   family  housing  securites  from  unex-
  pended   proceeds   due   to   insufficient   demand,   because  conventional
  mortgage   loans   may  become  available  at  interest  rates  equal  to  or
  less   than   the   interest   rates  charged  on  the  mortgage  loans  made
  available   from   bond   proceeds.   In  addition,  certain  mortgage  loans
  may   be   prepaid  earlier  than  their  maturity  dates,  because  mortgage
  loans   made   with   bond   proceeds   usually   do   not  carry  prepayment
  penalties.
  Multi-Family Housing Securities.
       Enacted    in   1980,   Section   103(b)(4)(A)   of   the   1954   Code,
  among  other  things,  required  that  at  least  20%  of  the  Units in each
  rental   housing   project   financed  pursuant  to  its  provisions  be  oc-
  cupied,   in   effect,   by  persons  with  low  and  moderate  incomes.  The
  1986   Code   further  restricted  the  amount  of  bond  proceeds  that  can
  be   spent   on   unqualified  costs  in  a  housing  project,  and  extended
  existing   and   added   certain   post-issuance   compliance   requirements,
  such   as   the   low   or   moderate   income  occupancy  requirements,  the
  determination   of   income   limitations,  continuous  rental  requirements,
  annual    current    income   determinations   and   the   arbitrage   rebate
  requirement.   The   IRS   has   undertaken  a  review  of  a  representative
  statistical   sample   of   multi-family   housing   bonds  issued  in  1984,
  primarily   to   determine   post-issuance  compliance  matters.  If  a  bond
  issue   is   determined  by  the  IRS  to  not  be  in  compliance  with  the
  Code,   income   derived   from   such   securities   may  be  deemed  to  be
  taxable   income.   The   Sponsor   is   unable   to  determine  whether  the
  IRS   will   expand   its   review,  the  outcome  of  any  such  review,  or
  whether  such  review  will  have  an  impact  on  any  of  the Securities in
  the   Trust.   Authorizing   state   statutes  may  have  imposed  additional
  program   requirements.   Additional   considerations   include:   increasing
  operating  costs;  the  ability  or  failure  to increase rental charges; and
  the  financial  condition  of  housing  authority  Issuers  and their ability
  to   meet   certain   requirements   under  the  Section  8  program  of  the
  United States Housing Act of 1937, as amended.
       Multi-family   housing  securities  may  also  be  subject  to  full  or
  partial  redemption  at  par  from  the  proceeds  of  the  sale,  assignment
  or   disposition   of   a   defaulted   mortgage   loan  or  acceleration  of
  principal   payments   thereunder;   a   condemnation   or  insurance  award;
  or a result of the reduction of a required reserve fund.

  Airport Facilities
       Bonds   in   the  airport  facilities  category  are  payable  from  and
  secured    by   revenues   derived   from   the   gross   airport   operating
  income.   The   major   portion   of   gross   airport  operating  income  is
  generally  derived  from  fees  received  from  signatory  airlines  pursuant
  to   use   agreements   which   consist   of   annual  payments  for  airport
  use,   occupancy   of  certain  terminal  space,  facilities,  service  fees,
  concessions   and   leases.   Airport   operating   income  may  be  affected
  by   local   economic  conditions,  air  traffic  patterns,  noise  abatement
  restrictions  or  the  ability  of  the  airlines  to  meet their obligations
  under  the  use  agreements.  The  air  transport  industry  is  experiencing
  significant   variations   in  earnings  and  traffic  due  to  deregulation,
  recent   consolidations   through   mergers   and   acquisitions,  fair  com-
  petition,   excess   industry   capacity,  fluctuations  in  fuel  and  other
  costs,  traffic  constraints  and  other  factors.  In particular, facilities
  with   use   agreements   involving   airlines  experiencing  financial  dif-
  ficulty   may   experience  a  reduction  in  revenue  due  to  the  possible
  inability  of  these  airlines  to  meet  their  use  agreement  obligations.
  Additionally,   the   FAA   has   established  a  schedule  for  retrofitting
  certain   existing   aircraft   to  comply  with  operating  noise  standard.
  The   Sponsor   is   now   unable   to  predict  what  effect,  if  any,  air
  transport  industry  conditions  will  have  on  the  airport  Bonds  in  the
  Trust.
  Hospital Facility Securities
       Bonds   in   the   hospital   facilities   category   are  payable  from
  revenues   derived   from   hospital   and   health  care  facilities  which,
  generally,   were   constructed   or   are   being   constructed   with  bond
  proceeds.  The  continuing  availability  of  sufficient  revenues  is depen-
  dent   upon   several   factors  affecting  all  such  facilities  generally,
  including,  among  other  factors:  utilization  rates;  the  cost and avail-
  ability   of   malpractice   insurance   and   the   outcome  of  malpractice
  litigation;   curtailment   of  operations  due  to  shortages  in  qualified
  medical  staff  or  labor  disputes;  changes  in  Federal, state and private
  reimbursement   regulations   and   health   care   delivery   programs.  The
  extent   of   the   AIDS   epidemic   is   undetermined,   and   the  Sponsor
  cannot  predict  its  full  impact  on  the  health care system or particular
  issuers.  Utilization  rates  for  a  particular  facility  may be determined
  by    cost   containment   programs   implemented   by   third   party   gov-
  ernmental    providers   or   private   insurers;   long-term   advances   in
  health   care   delivery  reducing  demand  for  in-patient  services;  tech-
  nological   developments   which   may   be   effectively   rationed  by  the
  scarcity   of   equipment  or  specialists;  governmental  approval  and  the
  ability   to   finance  equipment  acquisitions;  increased  competition  due
  to   elimination   of  certain  certificate  of  need  requirements  in  some
  states;   and   physicians'   and  public  perceptions  as  to  standards  of
  care.   Requirements  for  Federal  or  state  licenses,  certifications  and
  contract  eligibility  and  for  accreditation  are  subject  to  change, and
  may  require  participating  facilities  to  effect  costly  modifications in
  operations.   Prior  to  June  30,  1984,  participating  facilities  in  the
  Medicare   program   were   reimbursed   for   their   reasonable   costs  of
 <PAGE>
  furnishing   services;   thereafter,   the  Social  Security  Amendments  Act
  of   1983   mandated   implementation   over   a   four   year  period  of  a
  prospective   payment   system,   based   upon   diagnosis   related   groups
  ("DRGs"),   for   most   in-patient   services.   DRG   reimbursement  rates,
  because   they   are   set   by   the   Federal  government,  may  not  fully
  cover   the   actual   cost   of   furnishing   services  by  any  particular
  hospital,   and   Federal   law   prohibits   health   care   providers  from
  passing   along   the   excess  costs  to  Medicare  beneficiaries.  Medicare
  payments    have    been,   and   may   continue   to   be,   reduced   under
  legislation   adopting  deficit  reduction  measures.  Additionally,  certain
  states   have   recently   implemented   prospective   payment   systems  for
  their   Medicaid   programs,   and   have   adopted  other  changes,  includ-
  ing  enrollment  restrictions.  The  Sponsor  cannot  predict  the effect, if
  any,   of   the   DRG  system  or  of  further  reductions  in  Medicare  and
  Medicaid   payments  on  the  revenues  of  Issuers  of  hospital  Securities
  in   the   Trust.   Many   hospitals,   including  certain  issuers  (or  the
  conduit  obligors)  of  Securities  in  the  Trust,  have  been  experiencing
  significant   financial   difficulties   in   recent  years.  The  number  of
  hospital   closings   has  increased  during  the  late  1980s,  particularly
  among   smaller   institutions   located   in   rural  or  inner-city  areas.
  Hospital   revenues   nationwide   are   primarily   derived   from   private
  insurers,    many   of   which   have   experienced   significant   operating
  losses   in   recent   years.   The   Medicare   program   accounts   for  an
  increasing  share  of  hospital  revenues  nationwide,  and  is  financed  by
  the   Hospital   Insurance   Trust   Fund   through   payroll   taxes.  Based
  upon   preliminary  projections  including  increased  payroll  taxes  effec-
  tive   in   1991   (but   not   accounting  for  any  recession)  the  Fund's
  trustees  have  forecast  that  expenditures  will  exceed  tax  revenues  by
  1999   and   that   the   Fund  will  be  insolvent  in  2005.  Generally,  a
  number   of   additional   legislative   proposals   concerning  health  care
  may   be  introduced  in  Congress  at  any  time.  Recently,  these  propos-
  als   have   covered  a  wide  range  of  topics,  including  cost  controls,
  national  health  insurance,  incentives  for  competition  in  the provision
  of  health  care  services,  tax  incentives  and penalties related to health
  care   insurance   premiums,   and   promotion   of   prepaid   health   care
  plans.  The  Sponsor  is  unable  to  predict  the  effect  of  any  of these
  proposals, if enacted, on any of the Bonds in the Trust portfolio.
  Power and Electric Facility Securities
       These   Securities  are  typically  secured  by  revenues  derived  from
  power   generationg   facilities,   which  generally  include  revenues  from
  the   sale  of  electricity  generated  and  distributed  by  power  agencies
  using   hydroelectric,   nuclear,   fossil   fuel  or  other  power  sources.
  Certain  aspects  of  the  operation  of  such  facilities, particularly with
  regard   to   generation   and  transmission  at  the  wholesale  level,  are
  regulated   by   the   Federal   Energy   Regulatory   Commission   ("FERC");
  more   extensive  regulation  (affecting  retail  rate  structures)  is  pro-
  vided   by   state   public   service   commissions.   Special  condiseratons
  include:   restrictions   on   operations  and  increased  costs  and  delays
  attributable  to  environmental  statues  and  regulations;  the difficulties
  of  the  utilities  in  financing  or  refinancing  large  construction  pro-
 <PAGE>
  grams   and   of   the   capital   markets  in  absorbing  utility  debt  and
  equity  securities;  fluctuations  in  fuel  supplies  and  costs,  and costs
  associated   with   conversion   to  alternate  fuel  sources;  uncertainties
  with    regard    to    demand   projections   due   to   changing   economic
  conditions,    implementation    of    energy   conservation   measures   and
  competitive   cogeneration   projects;   and   other   technical   and   cost
  factors.   Recent  scientific  breakthroughs  in  fusion  energy  and  super-
  conductive   materials   may  cause  current  technologies  for  the  genera-
  tion   and   transmission  of  electricity  to  become  obsolete  during  the
  life  of  the  Securities  in  the Portfolio. Issuers relying upon hydroelec-
  tric   generation   may   encounter   contests  when  applying  for  periodic
  renewal   of   licenses   from   FERC   to   operate  dams.  Issuers  relying
  upon  coal  as  a  fuel  source  may  be  subject  to  significant  costs and
  operating   restrictions   to   comply  with  emission  standards  which  may
  be   adopted   to   alleviate   the   problems  associated  with  acid  rain.
  Issuers  relying  upon  fossil  fuel  sources  and  located  in  air  quality
  regions   designated   as   nonattainment   areas   may   become  subject  to
  pollution    control   measures   (which   could   include   abandonment   of
  construction   projects   in  progress,  plant  shutdowns  or  relocation  of
  facilities)  ordered  pursuant  to  the  Clean  Air  Act.  In  addition, such
  Securities   are   sometimes   secured  by  payments  to  be  made  to  state
  and   local   joint   action   power  agencies  pursuant  to  "take  or  pay"
  agreements.    Such    agreements    have    been   held   unenforceable   by
  state   courts   in   Idaho,   Vermont   and   Washington,  which  may  cause
  an   examination  of  the  legal  structure  of  certain  projects  in  other
  states   and  could  possibly  lead  to  litigation  challenging  the  enfor-
  ceability of such agreements.
       Some   of   the   issuers   of   Securities   in   the  Trust  may  own,
  operate  or  participate  on  a  contractual  basis  with  nuclear generating
  facilities,   which  are  licensed  and  regulated  by  the  Nuclear  Regula-
  tory   Commission   (the   "NRC").  Issuers  of  such  securities  may  incur
  substantial   expenditures   as  a  result  of  complying  with  NRC  requir-
  ments.   Additional   considerations  include:  the  frequency  and  duration
  of   plant   shutdowns   and   associated   costs   due   to  maintenance  or
  safety   considerations;   the  problems  and  associated  costs  related  to
  the   use   and   disposal   of   radiocactive   materials   and   wastes  in
  compliance   with   Federal  and  local  law;  the  implementation  of  emer-
  gency   evacuation  plans  for  areas  surrounding  nuclear  facilities;  and
  other   issues   associated   with   construction,   licensing,   regulation,
  operation   and   eventual   decommissioning   of   such   facilities.  These
  Securities   may   be   subject   to  industry-wide  fluctuations  in  market
  value   as   a   consequence   of   market   perception   of  certain  highly
  publicized   events,   as   in   the  Washington  Public  Power  Supply  Sys-
  tem's   defaults  on  its  Project  4  and  5  revenue  bonds  and  the  1988
  bankruptcy   filing   by   the   Public  Service  Corporation  of  New  Hamp-
  shire.  Federal,  state  or  municipal  governmental  authorities,  or voters
  by  initiative,  may  from  time  to  time  impose  additional regulations or
  take   such   other   governmental   action   which  might  cause  delays  in
  the  licensing,  construction  or  operation  of  nuclear  power  plants,  or
 <PAGE>
  the   suspension   or  cessation  of  operations  of  facilities  which  have
  been  or  are  being  financed  by  proceeds  of  certain  Securities  in the
  Trust.
  Industrial Development/Pollution Control Securities
       These   Securities   were   generally  issued  prior  to  the  enactment
  of   1986   Code   restrictions,   and  are  typically  secured  by  payments
  made   under   a   loan   agreement  entered  into  between  the  issuer  and
  the  obligor.  In  some  cases,  the  Securities  were  additionally  secured
  by   guarantees   provided   by   corporate   guarantors  or  by  a  stand-by
  letter  of  credit  issued  by  a  bank.  Special considerations include: the
  financial  condition  of  the  corporate  obligor  (or guarantor), especially
  as   it   may   be   affected   by   subsequent  corporate  restructuring  or
  changes in corporate control.
  Public Facilities Securities
       These   Securities  are  typically  secured  by  revenues  derived  from
  either   (i)   payments   appropriated   by  governmental  entities  for  the
  use  of  equipment  or  facilities,  such  as  administrative or correctional
  buildings,  or  (ii)  user  charges  or  other  revenues  derived  from  such
  operations  as  parking  facilities,  convention  centers  or  sports arenas.
  In  the  first  instance,  the  pledged  revenues  may  be  subject to annual
  appropriation  by  legislative  body.  In  the latter case, the collection of
  revenues   may  be  dependent  upon  the  reliability  of  feasibility  fore-
  casts and assumptions concerning utilization rates.
  Resource Recovery/Solid Waste Securities
       These   Securities  are  typically  secured  by  revenues  derived  from
  the   sale  of  electricity  or  steam  generated  as  a  by-product  of  the
  process   of   incinerating   solid   waste,  and  from  contractual  tipping
  fees,   user  charges  and  ancillary  recycling  earnings.  Special  consid-
  erations  include:  the  supply  of  solid waste at levels sufficient for the
  facility  to  operate  at  design  capacity;  the  frequency  and duration of
  plant   shutdowns   for  maintenance;  the  treatment  and  disposal  of  fly
  ash   which   contains   toxic   substances,  especially  dioxin;  compliance
  with   air   pollution   control   standards;  unanticipated  problems  asso-
  ciated  with  the  use  of  developing  technologies;  and  the  continuation
  of  FERC  policies  facilitating  congeneration  and its certification of any
  particular   qualifying  facility.  Governmental  service  contract  payments
  may  be  subject  to  annual  appropriation  by  a  legislative  body.  Older
  facilities   may   require  retrofitting  to  accommodate  new  technological
  developments or to comply with environmental standards.
  Water and Sewer Facility Securities
       Bonds   described   as   "water   and   sewer"   facilities   Bonds  are
  typically   secured   by   a   pledge   of  the  net  revenues  derived  from
  connection   fees   and   user   charges  imposed  by  the  enterprise.  Such
  Bonds  are  subject  to  the  risks  typically  associated  with construction
  projects.   Among   the  factors  which  may  affect  net  revenues  are  the
  destruction  of  facilities  due  to  natural  or other disasters; relocation
  out   of   the  service  area  by  a  major  customer  or  customers  due  to
 <PAGE>
  economic   factors  beyond  the  issuer's  control;  or  costs  incurred  due
  to   prior  periods  of  deferred  maintenance  or  compliance  with  Federal
  or   state   environmental   standards.   Water   system   revenues   may  be
  additionally  affected  by  the  terms  of  supply  allocations  and  service
  agreements   with   major   wholesale   customers   and   the  imposition  of
  mandatory    conservation    measures   in   response   to   drought.   Sewer
  system   revenues   may   be   additionally   affected  by  costs  to  comply
  with  effluent  and  other  standards  pursuant  to  the  Federal  and  state
  laws.
  Refunded Bonds
       Refunded   bonds   (including   bonds   escrowed   to  a  call  date  or
  maturity   date)   are  bonds  that  originally  had  been  issued  generally
  as   revenue   bonds   but   have   been   refunded  for  reasons  which  may
  include   changing   the   issuer's  debt  service  requirements  and  remov-
  ing   restrictive   bond   covenants.   Typically,  a  refunded  bond  is  no
  longer   secured   by  a  pledge  of  revenues  received  by  an  issuer  but
  rather    by   an   escrow   fund   consisting   of   U.S.   Government   Ob-
  ligations.   In   such   cases   the   issuer   establishes  an  escrow  fund
  which  is  irrevocable  and  which  cannot  be  depleted  by  the  issuer  so
  long  as  debt  service  on  the  refunded  bonds  is  required  to  be paid.
  Each    escrow    fund   is   funded   with   U.S.   Government   Obligations
  which   are   designed   to   make   payments   on  the  refunded  bonds  and
  which   cannot   be   affected   by  a  default  of  the  issuer.  An  escrow
  agent   pays   principal,   redemption  premium,  if  any,  and  interest  on
  the   refunded   bond  from  the  principal  of  and  interest  on  the  U.S.
  Government   Obligations  in  the  escrow  fund.  The  Trust,  as  holder  of
  the  refunded  bonds,  is  entitled  to  receive  such  payment of principal,
  redemption   premium,   if  any,  and  interest  on  the  refunded  bonds  as
  it  is  paid  by  the  escrow  agents  out  of  the  respective refunded bond
  escrow funds.
  Student Loan Securities
       Student  loan  revenue  securities  are  issued  either  by  non  profit
  corporations   organized   for   the   purpose  of  acquiring  student  loans
  originated   under   the   Higher   Education   Act  or  public  agencies  or
  instrumentalities  of  a  state  created  to  provide  loans  for educational
  purposes.   Proceeds   of   securities  issued  by  such  entities  generally
  are   used  to  make  or  acquire  student  loans  which  are  guaranteed  by
  guaranty   agencies;   the   obligation   of  such  guaranty  agency  is  re-
  insured   by   the  U.S.  Secretary  of  Education  (the  "Secretary");  such
  reinsurance   obligation   may   range   from   80%  to  100%  based  on  the
  default   levels   for   loans   serviced  by  such  a  guaranty  agency.  In
  addition,   some   loans   may   be   insured   directly  by  the  Secretary.
  Bonds   issued   by  such  entities  are  generally  secured  by  and  depen-
  dent   upon   such   state   guarantee   programs,   Federal   insurance  and
  reimbursement    programs,   the   proceeds   from   payment   of   principal
  and   interest   on   the  underlying  student  loans  and  federal  interest
  subsidy   and/or   special  allowance  payments.  Failure  by  the  servicers
  of   student   loans   on  the  guaranty  agencies  guaranteeing  such  loans
  to   properly  service  and  enforce  the  loans  may  cause  the  reimburse-
 <PAGE>
  ments to decline or be withheld by the Secretary.
       Both   the   Higher   Education  Act  and  the  regulations  promulgated
  thereunder    have    been   the   subject   of   extensive   amendments   in
  recent   years,   and   the  Sponsor  can  give  no  assurance  that  further
  amendment   will   not   materially  change  the  provisions  or  the  effect
  thereof.  There  can  be  no  assurance  that  the  other  provisions  of the
  Higher   Education   Act   affecting  the  Federal  Guaranteed  Student  Loan
  Program will be continued in their present form.
       The   availability  of  various  Federal  payments  in  connection  with
  the   Federal   Guaranteed   Student  Loan  Program  is  subject  to  federal
  budgetary   appropriation.   In   recent  years,  legislation  has  been  en-
  acted   which   has  provided,  subject  to  certain  Federal  budget  expen-
  ditures   (including  expenditures  in  connection  with  the  Federal  Guar-
  anteed   Student   Loan  Program),  for  the  recovery  of  certain  advances
  previously    made    by   the   Federal   government   to   state   guaranty
  agencies  in  order  to  achieve  deficit  reduction.  No  representation  is
  made  as  to  the  effect,  if  any,  or  future  Congressional appropriation
  or   legislation   upon  expenditures  by  the  Department  of  Education  or
  upon the financial condition of any guaranty agency.
  Lease Payment Bonds
       Certain    Bonds    may   be   principally   secured   by   governmental
  lease   payments   which   in  turn  are  subject  to  the  budget  appropri-
  ations  of  the  participating  governmental  entity.  A  governmental entity
  that   enters   into   a  lease  agreement  cannot  obligate  future  govern-
  ments   to   make   lease  payments  but  generally  will  covenant  to  take
  such   action   as   is   necessary   to   include  all  lease  payments  due
  under   an   agreement   in  its  annual  budgets  and  to  make  the  appro-
  priations  therefor.  The  failure  of  a  governmental  entity  to  meet its
  obligations  under  a  lease  could  result  in  an  insufficient  amount  of
  funds   to   cover   payment   of   the   Bonds   secured   by   such   lease
  payments.
  Tax Allocation Bonds
       Bonds   described  as  "tax  allocation"  securities  are  payable  from
  and   secured   by   incremental   (increased)   tax  revenues  collected  on
  property   within   the  areas  where  redevelopment  projects,  financed  by
  bond   proceeds,   are   located   ("project   areas").   Payments  on  these
  bonds   are   expected   to   be   made   from  projected  increases  in  tax
  revenues   derived   from   higher   assessed  value  of  property  resulting
  from   development   in   the   particular  project  area  and  not  from  an
  increase  in  the  tax  rates.  Among  the  factors  which  could result in a
  reduction  of  the  allocated  tax  revenues  which  secure  a tax allocation
  Bond  are:  (i)  reduction  of,  or  a  less  than  anticipated  increase in,
  taxable   values   of   property  in  the  project  area,  caused  either  by
  economic   factors   beyond  the  issuer's  control  (such  as  a  relocation
  out   of  the  project  area  by  one  or  more  major  property  owners)  or
  by   destruction  of  property  due  to  natural  or  other  disasters;  (ii)
  successful   appeals   by  property  owners  of  assessed  valuations;  (iii)
  substantial   delinquencies  in  the  payment  of  property  taxes;  or  (iv)
  imposition   of   any   constitutional   or  legislative  property  tax  rate
 <PAGE>
  decrease.   Such   reduction   of   tax   revenues   could  have  an  adverse
  effect   on  an  issuer's  ability  to  make  timely  payments  of  principal
  and of interest on the Bonds.
  Crossover Refunding Bonds
       Certain   Bonds   in  the  Trust  may  be  cross-over  refunding  Bonds.
  Prior   to   a  specified  date,  (the  "Crossover  Date"),  such  bonds  are
  payable  solely  from  an  escrow  fund  invested  in  specified  securities.
  After   the   Crossover   Date  the  Bonds  are  payable  from  a  designated
  source   of   revenues.   Such   bonds   are   categorized   in   Part  A  as
  payable from such source of revenues.
  Bonds Backed by Letters of Credit
       The  Trust  may  contain  securities  that  are  secured  by  letters of
  credit   issued   by   commercial   or  savings  banks  which  may  be  drawn
  upon   (i)   if   an   issuer   fails  to  make  payments  of  principal  of,
  premium,  if  any,  or  interest  on  a  Bond  backed  by  such  a  letter of
  credit   or   (ii)  in  the  event  interest  on  a  Bond  is  deemed  to  be
  taxable   and   full  payment  of  principal  and  any  premium  due  is  not
  made  by  the  issuer.  The  letters  of  credit  are irrevocable obligations
  of   the   issuing   banks.  Banks  are  subject  to  extensive  governmental
  regulations.   The   profitability   of   the  banking  industry  is  largely
  dependent   upon   the  availability  and  cost  of  capital  funds  for  the
  purpose    of   financing   lending   operations   under   prevailing   money
  market   conditions.   Also,   general   economic   conditions  play  an  im-
  portant  part  in  the  operations  of  the  banking  industry  and  exposure
  to  credit  losses  arising  from  possible  financial  difficulties  of bor-
  rowers  or  other  issuers  having  letters  of  credit might affect a bank's
  ability to meet its obligations under a letter of credit.
                                      ****
       An   amendment   to   the   Federal   Bankruptcy  Act  relating  to  the
  adjustment   of   indebtedness   owed   by   any   political  subdivision  or
  public   agency   or  instrumentality  of  any  state,  including  municipal-
  ities,   became   effective   in   1979.  Among  other  things,  this  amend-
  ment   facilitates   the   use   of   proceedings  under  the  Federal  Bank-
  ruptcy  Act  by  any  such  entity  to  restructure  or  otherwise  alter the
  terms  of  its  obligations,  including  those  of  the  type  comprising the
  Trust's  portfolio.  The  Sponsor  is  unable  to  predict  at this time what
  effect, if any, this legislation will have on the Trust.
       Each  of  the  Bonds  in  the  Trust  was,  as  of  the Date of Deposit,
  rated   "A"   or   higher   by   either  Standard  &  Poor's  Corporation  or
  Moody's   Investors   Service,   Inc.  (see  "Schedule  of  Investments")  or
  were    Bonds    which   the   Sponsor   reasonably   believed   would   have
  obtained   such   minimum   rating  soon  thereafter.  Ratings  indicated  on
  the   Schedule   of   Investments   are   Standard   &   Poor's   Corporation
  ratings  unless  no  rating  was  given  to  a  Bond  by  such rating service
  or   the   rating  category  assigned  by  Moody's  Investors  Service,  Inc.
  was  higher,  in  which  case  the  Moody's  Investors  Service,  Inc. rating
  was   indicated.   Certain  Bonds  may,  in  addition  to  their  rating,  be
  designated   either   "p"   by   Standard   &  Poor's  Corporation  or  "Con"
 <PAGE>
  by   Moody's   Investors  Service,  Inc.  Such  designations  do  not  affect
  the  rating  assigned  by  the  respective  rating  services  to  such  Bonds
  but   provide   certain   additional   information  (see  "Bond  Ratings"  in
  Part B and "Schedule of Investments" in Part A).
                     ACQUISITION OF SECURITIES FOR THE TRUST
       In   selecting  Bonds  for  deposit  in  the  Trust  many  factors  were
  considered,   and   based   upon   the   experience   and   judgment  of  the
  Sponsor,   the   following   requirements,   among  others,  were  deemed  to
  be of primary importance:
       1.   Minimum   Standard   &  Poor's  Corporation's  rating  of  "A-"  or
  minimum   Moody's   Investors   Service,   Inc.'s  rating  of  "A"  ("invest-
  ment   grade"   municipal   bonds)   or   Bonds  which  the  Sponsor  reason-
  ably believes will obtain such minimum ratings in the near future;
       2.  Reasonable  value  relative  to  other  issues  of  similar  quality
  and maturity;
       3.   Diversification   as   to   the  purpose  of  each  issue  and  the
  location of each issuer; and
       4. Income to the Unitholders of the Trust.
       Cash,  if  any,  received  from  Unitholders  prior  to  the  settlement
  date   for  the  purchase  of  Units  or  prior  to  the  payment  for  Bonds
  upon   their   delivery  may  be  used  in  the  Sponsor's  business  subject
  to   the   limitations   of   17   C.F.R.   Section  240.  15c3-3  under  the
  Securities   and  Exchange  Act  of  1934  and  may  be  of  benefit  to  the
  Sponsor.
       The  Trustee  has  not  participated  in  the  selection  of  Securities
  for  the  Trust,  and  neither  the  Sponsor  nor  the Trustee will be liable
  in any way for any default, failure or defect in any Securities.
       To   the  best  knowledge  of  the  Sponsor,  there  was  no  litigation
  pending  as  of  the  Date  of  Deposit  in  respect  of any Securities which
  might   reasonably   be   expected   to   have   a  material  adverse  effect
  upon  the  Trust.  At  any  time  after  the  Date of Deposit, litigation may
  have  been  initiated  on  a  variety  of  grounds  with  respect  to Securi-
  ties  in  the  Trust.  Such  litigation  may  affect  the  validity  of  such
  Securities  or  the  tax-exempt  status  of  the  interest thereon. While the
  outcome   of   litigation  of  such  nature  cannot  be  predicted,  opinions
  of  the  bond  counsel  are  delivered  with  respect  to  each  Security  on
  the   date   of   issuance   to  the  effect  that  such  Security  has  been
  validly  issued  and  that  the  interest  thereon  is  exempt  from  Federal
  income   tax.   If  legal  proceedings  are  instituted  after  the  Date  of
  Deposit   seeking,   among   other   things,   to   restrain  or  enjoin  the
  payment   of   any   of   the  Bonds  or  attacking  their  validity  or  the
  authorization   or   existence   of   the   issuer,   the   Sponsor  may,  in
  accordance  with  the  Indenture,  direct  the  Trustee  to  sell  such Bonds
  and  distribute  the  proceeds  of  such  sale  to  Unitholders. In addition,
  other   factors   may   arise   from  time  to  time  which  potentially  may
  impair   the   ability   of  issuers  to  meet  obligations  undertaken  with
  respect to Bonds.

                         PUBLIC OFFERING PRICE OF UNITS
       The   Public  Offering  Price  per  Unit  during  the  secondary  market
  will  be  computed  by  dividing  the  aggregate  of  the  bid  prices of the
  Bonds   in   the  Trust  plus  any  money  in  the  Principal  Account  other
  than   money   required   to   redeem  the  tendered  Units,  by  the  number
  of   Units  outstanding,  and  then  adding  the  appropriate  sales  charge.
  If  the  primary  offering  period,  the  Public  Offering  Price  was deter-
  mined   on   the  basis  of  the  offering  prices  of  bonds  plus  a  sales
  charge ranging from 3.5% to 5.5% of the Public Offering Price.
       The  sales  charge  is  determined  in  accordance  with  the  table set
  forth   below   based   upon   the   number   of   years   remaining  to  the
  maturity   of   each   Bond.  There  is  no  sales  charge  with  respect  to
  cash  held  in  the  Interest  or  Principal  Accounts.  For purposes of this
  calculation,  Bonds  will  be  deemed  to  mature  on  their  stated maturity
  dates   unless:   (a)   the   Bonds   have  been  called  for  redemption  or
  funds   or   securities  have  been  placed  in  escrow  to  redeem  them  on
  an   earlier   call   date  ("Refunded  Bonds"),  in  which  case  such  call
  date  shall  be  deemed  to  be  the  date  upon  which  they  mature; or (b)
  such   Bonds   are   subject  to  a  "mandatory  put",  in  which  case  such
  mandatory   put   date   shall   be   deemed   to  be  the  date  upon  which
  they mature.
       The   effect  of  this  method  of  sales  charge  calculation  will  be
  that  different  sales  charge  rates  will  be  applied to the various Bonds
  in   a   Trust  portfolio  based  upon  the  maturities  of  such  Bonds,  in
  accordance with the following schedule:
                                    Maximum
                                   Percent of
           Remaining                 Public            Percent of
           Years to                 Offering           Net Amount 
           Maturity                  Price             Invested
           Less than 1                 0%                 0%
           1 but less than 6           3.50               3.63
           6 but less than 11          4.00               4.17
           More than 11                5.50               5.82
       For  example,  the  sales  charge  on  a  Trust  consisting  entirely of
  Bonds   maturing   in   13   to  16  years  would  be  5.50%  (5.82%  of  the
  net   amount   invested)   and   that  on  a  Trust  consisting  entirely  of
  Bonds   maturing   in   three   to  five  years  would  be  3.50%  (3.63%  of
  the   net   amount  invested).  The  actual  sales  charge  included  in  the
  Public   Offering   Price   of  any  particular  Trust  will  depend  on  the
  maturities of the Bonds in the portfolio of such Trust.
       Due  to  the  realization  of  economies  of  scale  in sales effort and
  sales   related   expenses   with   respect  to  the  purchase  of  Units  by
  employees   of   the   Sponsor,   the   Sponsor  intends  to  permit  employ-
  ees  of  the  Sponsor  and  certain  of  their  relatives  to  purchase Units
 <PAGE>
  of   the   Trust  at  a  price  equal  to  the  bid-side  evaluation  of  the
  Securities   in  the  Trust  divided  by  the  number  of  Units  outstanding
  plus a reduced sales charge of $5.00 per Unit.
       A   proportionate   share   of   accrued   interest   and  undistributed
  interest   on   the   Units   to   the   Unitholder's  settlement  date  (the
  Unitholder's   settlement   date  is  the  date  so  specified  in  the  con-
  firmation  of  sale  of  the  Units  to  a Unitholder, normally five business
  days   after   purchase)   is  added  to  the  Public  Offering  Price.  Such
  proportionate  share  will  be  an  asset  of  the  Unitholder  and  will  be
  received in subsequent distributions and upon the sale of his Units.
       Aggregate  bid  prices  of  the  Securities  will  be determined for the
  Trust  by  the  Evaluator  on  the  basis  of: (1) the current bid prices for
  the  Securities;  (2)  the  current  bid  prices  for  comparable  bonds,  if
  bid  prices  are  not  available  for  any of the Securities; (3) determining
  the   value   of   the   Securities   on  the  bid  side  of  the  market  by
  appraisal;   or   (4)   any   combination  of  the  above.  Such  evaluations
  and   computations   will   be   made   each   business   day   as   of   the
  Evaluation   Time,  effective  for  all  sales  or  redemptions  made  subse-
  quent to the last preceding determination.
       In  addition  to  the  sales  charges,  on  the  Date  of  Deposit,  the
  Sponsor   realized   a   profit   or   loss  resulting  from  the  difference
  between   the   purchase   price   paid   by   the   Sponsor   to   buy   the
  Securities  and  the  cost  of  the  Securities  to  the  Trust as determined
  by  the  Evaluator.  The  Sponsor  may  realize  additional  profit  or  loss
  as  a  result  of  the  possible  change  in  the  daily  evaluation  of  the
  Bonds   in  the  Trust.  All  proceeds  received  from  purchasers  of  Units
  of the Trust will be retained by the Sponsor.
                            PUBLIC OFFERING OF UNITS
       The  Sponsor  intends  to  qualify  Units  for sale in all of the states
  of   the   United   States,   except  that  for  state  trusts,  the  Sponsor
  intends  to  qualify  Units  for  sale only to residents of that state. Sales
  may   be   made   to   dealers  who  are  members  of  the  National  Associ-
  ation  of  Securities  Dealers,  Inc.  at  prices  which  include  a  conces-
  sion   of  75%  of  the  applicable  sales  charge  subject  to  change  from
  time   to  time.  The  difference  between  the  dealer  concession  and  the
  sales   charge  will  be  retained  by  the  Sponsor.  The  Sponsor  reserves
  the  right  to  reject,  in  whole  or in part, any order for the purchase of
  Units.
       Initial  Offering  of  Units. During the initial public offering period,
  Units   were   offered   to   the   public  by  the  Sponsor  at  the  Public
  Offering   Price  calculated  on  each  business  day,  plus  accrued  inter-
  est.
       Secondary  Offering  of  Units.  Upon  the  termination  of  the initial
  public   offering   period,   unsold   Units   or   Units   acquired  by  the
  Sponsor   in   the   secondary  market  referred  to  below  may  be  offered
  to  the  public  by  the  Sponsor  by  this  Prospectus  at  the then current
  Public Offering Price, calculated daily, plus accrued interest.
 <PAGE>
                           SECONDARY MARKET FOR UNITS
       While   not   obligated   to   do   so,  it  is  the  Sponsor's  present
  intention  to  maintain,  at  its  expense,  a  secondary  market  for  Units
  of   this   Series  and  to  continuously  offer  to  repurchase  Units  from
  Unitholders    at   the   "Sponsor's   Repurchase   Price".   The   Sponsor's
  Repurchase  Price  is  computed  by  dividing  the  value  of  the  Trust  by
  the   number   of   Units   outstanding  (see  "Evaluation  of  the  Trust").
  There   is   no   sales   charge  incurred  when  a  Unitholder  sells  Units
  back   to   the  Sponsor.  Any  Units  repurchased  by  the  Sponsor  at  the
  Sponsor's   Repurchase   Price   may  be  reoffered  to  the  public  by  the
  Sponsor   at   the   then   current   Public  Offering  Price,  plus  accrued
  interest.  Any  profit  or  loss  resulting  from  the  resale  of such Units
  will belong to the Sponsor.
       If   the   supply   of   Units   exceeds   demand,  or  for  some  other
  business   reason,   the  Sponsor  may  at  any  time  or  occasionally  from
  time  to  time  discontinue  the  repurchase  of  Units  of  this  Series  at
  the   Sponsor's   Repurchase   Price.   In  such  event,  although  under  no
  obligation  to  do  so,  the  Sponsor  may,  as  a  service  to  Unitholders,
  offer  to  repurchase  Units  at  the  "Redemption  Value".  If  the  Sponsor
  repurchases    Units   in   the   secondary   market   at   the   "Redemption
  Value",   it  may  reoffer  these  Units  in  the  secondary  market  at  the
  "Public  Offering  Price".  In  no  event  will  the  price  offered  by  the
  Sponsor   for   the   repurchase   of   Units   be   less  than  the  current
  Redemption   Value   for   those   Units.   See   "Redemption   of  Units  by
  Trustee"   and   "Comparison   of   Public   Offering  Price  and  Redemption
  Value".
                ESTIMATED CURRENT RETURN AND ESTIMATED LONG TERM
                                     RETURN-
       The   Sponsor   may   from   time   to  time  give  investors  Estimated
  Current   Return   and   Estimated   Long   Term   Return  information,  each
  of   which   give   investors   different   information   about  the  return.
  Estimated   Current   Return  on  a  Unit  represents  annual  cash  receipts
  from   coupon-bearing   debt   obligations  in  the  Trust  (after  estimated
  annual  expenses)  divided  by  the  Public  Offering  Price  (including  the
  sales charge).
       Unlike   Estimated   Current   Return,   Estimated   Long   Term  Return
  is  a  measure  of  the  estimated  return  to  the  investor earned over the
  estimated   life   of   the   Trust.  Estimated  Long  Term  Return  is  cal-
  culated   using   a   formula   which   (1)  takes  into  consideration,  and
  determines   and   factors   in   the  relative  weightings  of,  the  market
  values,   yields  (which  takes  into  account  the  amortization  of  premi-
  ums   and   the   accretion   of  discounts)  and  estimated  retirements  of
  all  of  the  Securities  in  the  Trust  and  (2)  takes  into  account  the
  expenses    and   maximum   sales   charge   associated   with   each   Unit.
  The   Estimated   Long   Term   Return   calculation   does   not  take  into
  account  certain  delays  in  distributions  of  income  and  the  timing  of
  other   receipts   and   distributions   on   Units  and  may,  depending  on
  maturities,  over  or  understate  the  impact  of  sales  charges.  Both  of
  these factors may result in a lower figure.
 <PAGE>
       Both   Estimated   Current   Return   and   Estimated   Long   Term  Re-
  turn   are   subject  to  fluctuation  with  changes  in  Trust  composition,
  changes  in  market  value  of  the  underlying  Securities  and  changes  in
  fees   and   expenses,   including  sales  charges.  The  size  of  any  dif-
  ference   between   Estimated   Current   Return   and  Estimated  Long  Term
  Return  can  also  be  expected  to  fluctuate  at  least  as  frequently. In
  addition,  both  return  figures  may  not  be  directly  comparable to yield
  figures   used   to   measure   other  investments,  and,  since  the  return
  figures   are   based  on  certain  assumptions  and  variables,  the  actual
  returns received by a Unitholder may be higher or lower.
                  ESTIMATED NET ANNUAL INTEREST INCOME PER UNIT
       The  estimated  Net  Annual  Interest  Income  per  Unit  of  the  Trust
  is   computed   by  dividing  the  total  gross  annual  interest  income  to
  the   Trust   by  the  number  of  Units  outstanding  and  then  subtracting
  the  per  Unit  estimated  annual  fees  and  expenses  of  the  Trustee, the
  Sponsor   and   the  Evaluator  (see  "Essential  Information"  in  Part  A).
  The  estimated  Net  Annual  Interest  Income  per  Unit  will  be higher for
  Unitholders   who   do   not   elect   the   monthly  plan  (where  alternate
  plans  of  distribution  are  available). This is the result of the differing
  expenses   and  fees  of  the  Trustee  in  administering  the  distributions
  of  interest.  See  "Essential  Information"  in  Part  A  and "Distributions
  to Unitholders".
       The   estimated   Net  Annual  Interest  Income  per  Unit  will  change
  whenever   Securities  mature,  are  called  for  redemption,  or  are  sold.
  In   addition,   any   change   in   the   Trustee's,  the  Sponsor's  (where
  applicable)  or  Evaluator's  fees  or  expenses  will  result in a change in
  the   estimated   Net   Annual   Interest  Income  per  Unit  (see  "Expenses
  of the Trust").
                          DISTRIBUTIONS TO UNITHOLDERS
       The   Trustee  will  collect  the  interest  on  the  Securities  as  it
  becomes   payable   and   credit   such   interest  to  a  separate  Interest
  Account   created   by   the   Indenture.   All   moneys   received   by  the
  Trustee   from   sources   other   than   interest  will  be  credited  to  a
  separate   Principal  Account.  All  funds  collected  or  received  will  be
  held  by  the  Trustee  in  trust  without  interest  to  Unitholders as part
  of  the  Trust  or  the  Reserve  Account  referred  to  below until required
  to  be  disbursed  in  accordance  with  the  provisions  of  the  Indenture.
  Such   funds  will  be  segregated  by  separate  recordation  on  the  Trust
  ledger   of   the  Trustee  so  long  as  such  practice  preserves  a  valid
  preference   under   applicable   law,   or,   if   such  preference  is  not
  preserved   the  Trustee  shall  handle  such  funds  in  such  other  manner
  as   shall   constitute   the   segregation  and  holding  thereof  in  trust
  within   the   meaning  of  the  Investment  Company  Act  of  1940,  as  the
  same   may   be   from   time  to  time  amended.  To  the  extent  permitted
  by   the  Indenture  and  applicable  banking  regulations,  such  funds  are
  available   for  use  by  the  Trustee  pursuant  to  normal  banking  proce-
  dures.
       The  Trustee  is  authorized  by  the  Indenture  to  withdraw  from the
  Principal    and/or    Interest   Accounts   such   amounts   as   it   deems
 <PAGE>
  necessary   to  establish  a  reserve  for  any  taxes  or  other  governmen-
  tal   charges   that   may  be  payable  out  of  the  Trust,  which  amounts
  will   be   deposited   in   a  separate  Reserve  Account.  If  the  Trustee
  determines   that   the  amount  in  the  Reserve  Account  is  greater  than
  the   amount   necessary   for   payment   of   any   taxes   or  other  gov-
  ernmental   charges,   it   will   promptly   deposit   the   excess  in  the
  Account from which it was withdrawn.
       The  settlement  date  for  the  purchase  of  Units  must  occur  on or
  prior   to   the   Record  Date  in  order  for  a  purchaser  to  receive  a
  distribution  on  the  next  Distribution  Date.  If  the settlement date for
  the  purchase  of  Units  occurs  after  the  Record  Date, distribution will
  not occur until the second following Distribution Date.
  Interest Account
       After   deduction   of  the  fees  and  expenses  of  the  Trustee,  the
  Sponsor   (where   applicable   and   as   indicated   under  "Essential  In-
  formation")   and   the  Evaluator,  the  Trustee  will  distribute  on  each
  Distribution  Date  or  shortly  thereafter,  to  Unitholders  of  record  on
  the   preceding   Record  Date,  an  amount  approximately  equal  to  either
  one-twelfth,   one-quarter   or   one-half  of  such  Unitholder's  pro  rata
  share  (depending  on  the  distribution  plans  available  and  selected) of
  the   estimated   annual   amount   to  be  deposited  in  the  Interest  Ac-
  count,   computed   as   of   the   preceding   Record   Date.  However,  all
  Unitholders   of   record  on  the  initial  Record  Date  will  receive  the
  initial  interest  distribution  on  the  initial Interest Distribution Date.
  The  Trustee's  fees  and  expenses  will  be  higher  for  monthly  interest
  distributions  than  for  quarterly  or  semi-annual  interest distributions,
  where   available.   Therefore,   the   amount   distributed   per   Unit  to
  Unitholders   electing   the  monthly  plan  will  be  correspondingly  lower
  than  under  the  quarterly  or  semi-annual  plan.  All  interest  distribu-
  tions  following  the  initial interest distribution will be in approximately
  the    amounts    shown   under   "Essential   Information",   depending   on
  the  plan  of  distribution  selected.  See  "Essential  Information--Plan of
  Distribution"  in  Part  A  for  details  on  electing available distribution
  plans.
       Because   the   Securities   in   the  Trust  pay  interest  at  varying
  semi-annual   intervals   and   Units   pay  interest  at  constant  monthly,
  quarterly  or  semi-annual  intervals,  the  interest  accrued  on  Units  of
  the  Trust  will  be  greater  than  the  amount  available  for distribution
  from   the   Interest   Account.   The   Trustee   will  distribute  on  each
  Distribution   Date   an   amount  which  will  be  less  than  the  interest
  accrued   to   each   Unitholder  on  the  preceding  Record  Date.  Pursuant
  to  the  Indenture,  in  order  to  accommodate  regular  interest  distribu-
  tions,   the  Trust  will  contain  undistributed  cash  balances.  The  dif-
  ference    between   the   amount   accrued   to   each   Unitholder   on   a
  Record   Date   and   the  amount  distributed  on  the  following  Distribu-
  tion  Date  is  an  asset  of  the  Unitholder  and  will be included as part
  of   accrued   interest   which  will  be  received  in  subsequent  interest
  distributions,  upon  the  sale  of  his  Units  or,  in part, upon the sale,
  redemption, or maturity of Securities in the Trust.
       The   Trustee   is   authorized   by   the  Indenture  to  advance  such
 <PAGE>
  amounts   as   may   be   necessary  to  provide  interest  distributions  of
  approximately   equal   amounts   in   accordance   with   the   distribution
  plan  selected.  The  Trustee  will  be  reimbursed,  without  interest,  for
  any such advances in the manner provided in the Indenture.
  Principal Account
       The   Trustee   will   distribute  an  amount  equal  to  such  Unithol-
  der's  pro  rata  share  of  the  cash  balance,  if  any,  in  the Principal
  Account  on  the  principal  Distribution  Date  specified  under  "Distribu-
  tion"   under  "Essential  Information".  The  pro  rata  share  is  computed
  as   of   the   preceding   Record   Date.   Except   for   moneys   used  to
  redeem   tendered   Units,   proceeds   received   upon  the  disposition  of
  any   Securities   subsequent   to   a   Record   Date   and   prior  to  the
  following   principal  Distribution  Date  will  be  held  in  the  Principal
  Account   and   will   not   be   distributed   until   the  next  succeeding
  principal   Distribution   Date.   However,   in   the   event  of  an  early
  redemption   of   bonds,   sale  of  bonds  upon  the  occurrence  of  events
  set   forth   under  "Supervision  of  Trust  Investments",  or  maturity  of
  bonds,  there  may  occur  a  special  principal  distribution.  Any  special
  principal  distribution  will  be  made  within  60  days  of  such  event to
  Unitholders   of   record  on  the  Record  Date  selected  therefor  by  the
  Trustee   as  provided  in  the  Indenture.  No  distribution  need  be  made
  from  the  Principal  Account  if  the  cash  balance  therein  is  less than
  one-tenth   of   one   per   cent  of  the  total  principal  amount  of  the
  Securities on the Date of Deposit.
       Certain  of  the  Bonds  in  the  Trust  are  subject to sinking fund or
  special   redemption  by  their  issuers,  as  set  forth  under  "Redemption
  Features"   on   the  "Schedule  of  Investments  in  Part  A".  The  redemp-
  tion   price  of  Bonds  in  the  Trust  called  by  an  issuer  pursuant  to
  sinking  fund  or  special  redemption  is  normally  equal  to the principal
  amount   of   such  Bonds,  while  the  redemption  price  for  Bonds  called
  at   the   option  of  the  issuer  may  include  a  redemption  premium.  In
  most   cases   Bonds   are   selected   from   among  Bonds  of  like  series
  and   maturity  either  by  lot  or  by  such  method  as  the  bond  trustee
  may   adopt.   A   capital   gain  or  loss  may  occur  depending  upon  the
  price   at   which  a  Bond  which  is  called  was  acquired  by  the  Trust
  and   the   amount   received   by   the  Trust  upon  redemption  (see  "Tax
  Status  of  the  Trust").  In  general,  optional  redemption  provisions are
  more   likely   to   be  exercised  by  an  issuer  when  the  offering  side
  valuation  is  greater  than  par  than  when  the offering side valuation is
  less  than  par.  If  future  interest  rates  decline,  an  issuer  of Bonds
  might  find  it  advantageous  to  exercise  its  option  to call Bonds prior
  to   maturity   even   though,   in   most  cases,  the  issuer  must  pay  a
  premium.
  Reinvestment Program
       Distributions   are   made   to   Unitholders  monthly.  The  Unitholder
  has   the   option   of   receiving  the  monthly  interest  interest  and/or
  principal   distribution   or   reinvesting   at   net  asset  value  in  the
  PaineWebber    Tax-Exempt    Income    Fund   (the   "Fund"),   an   open-end
  investment   company   registered   under   the   Investment   Company   Act.
 <PAGE>
  The   Fund's   investment   objective  is  to  provide  high  current  income
  exempt   from  Federal  income  tax,  consistent  with  the  preservation  of
  capital   and   liquidity   within   the  Fund's  quality  standards.  Except
  under   unusual  market  conditions,  the  Fund  will  invest  at  least  80%
  of   its  assets  in  municipal  obligations  with  varying  maturities,  the
  interest   from   which,   in   the   opinion   of   bond  counsel  to  their
  respective   issuers,  is  exempt  from  both  Federal  income  tax  and  the
  Federal  alternative  minimum  tax.  There  can  be  no  assurance  that  the
  Fund  will  achieve  its  objective.  For  more  information  about the Fund,
  including   a   prospectus,   Unitholders   should  contact  their  PaineWeb-
  ber   Investment   Executive   or   call   the   Fund's  shareholder  service
  number at 1-800-544-9300.
       To   participate   in   the   Reinvestment   Program,  Unitholders  must
  hold  Units  in  their  own  name,  must  fill  out an application establish-
  ing   an   account   and   notify  the  Trustee  of  the  account  number  at
  least   10   days   before   the   Record  Date.  Elections  may  be  revoked
  upon similar notice.
                                 EXCHANGE OPTION
       Unitholders  may  elect  to  exchange  any  or  all  of  their  Units of
  this  series  for  units  of  one  or  more  of  any  series  of  PaineWebber
  Municipal    Bond    Fund    First   Series;   PaineWebber   Municipal   Bond
  Fund   Second   Series;   PaineWebber   Municipal   Bond   Fund   Third   Se-
  ries   (the   "PaineWebber   Series");   The   Municipal  Bond  Fund,  Series
  One   through   Series   Forty-Three;   The   Municipal  Bond  Trust,  Series
  Forty-Four   and   subsequent   series   (the  "National  Series");  The  Mu-
  nicipal   Bond   Trust,   Multi-State   Program  Series  One  and  subsequent
  series   (the  "Multi-State  Series);  The  Municipal  Bond  Trust,  Califor-
  nia   Series   A   and  subsequent  series  (the  "California  Series");  The
  Municipal   Bond   Trust,   Insured   Series   One   and   subsequent  series
  (the   "Insured   Series");   The   Corporate  Bond  Trust,  Series  One  and
  subsequent   series   (the   "Corporate   Series");   The  PaineWebber  Path-
  finders   Trust,   Treasury   and  Growth  Stock,  Series  1  and  subsequent
  series   (the   "Pathfinders   Trust"),   the   PaineWebber  Federal  Govern-
  ment   Trust,   GNMA   Series   1  and  subsequent  Series  1  (the  "Federal
  Government   Trust")   or   the   PaineWebber   Equity  Trust,  Growth  Stock
  Series   1   and   subsequent   series  (the  "Equity  Trust")  (collectively
  referred  to  as  the  "Exchange  Trusts"),  at  a  Public Offering Price for
  the  units  of  the  Exchange  Trusts  to  be  acquired  based  on  a reduced
  sales   charge   of   $15  per  unit.  The  purpose  of  such  reduced  sales
  charge   is  to  permit  the  Sponsor  to  pass  on  to  the  Unitholder  who
  wishes   to   exchange   Units   the   cost   savings   resulting  from  such
  exchange   of  Units.  The  cost  savings  result  from  reductions  in  time
  and   expense   related   to   advice,  financial  planning  and  operational
  expense   required   for   the  Exchange  Option.  Each  Exchange  Trust  has
  different   investment   objectives,   therefore  a  Unitholder  should  read
  the   prospectus  for  the  applicable  Exchange  Trust  carefully  prior  to
  executing  this  option.  Exchange  Trusts  having  as  their  objective  the
  receipt  of  tax  exempt  interest  income  would  not  be  suitable  for tax
  deferred   investment   plans  such  as  Individual  Retirement  Accounts.  A
 <PAGE>
  Unitholder   who   purchased   Units   of  a  series  and  paid  a  per  unit
  sales   charge  that  was  less  than  the  per  Unit  sales  charge  of  the
  series   of   Exchange   Trusts   for   which   such  Unitholder  desires  to
  exchange   into,   will  be  allowed  to  exercise  the  Exchange  Option  at
  the  Unit  Offering  Price  plus  the  reduced  sales  charge,  provided  the
  Unitholder   has   held  the  Units  for  at  least  five  months.  Any  such
  Unitholder   who   has   not   held   the  Units  to  be  exchanged  for  the
  five-month   period   will   be   required  to  exchange  them  at  the  Unit
  Offering   Price   plus   a   sales  charge  based  on  the  greater  of  the
  reduced  sales  charge,  or  an  amount  which,  together  with  the  initial
  sales   charge   paid  in  connection  with  the  acquisition  of  the  Units
  being   exchanged,   equals   the   sales   charge   of  the  series  of  the
  Exchange   Trust   for  which  such  Unitholder  desires  to  exchange  into,
  determined as of the date of the exchange.
       The   Sponsor   will  permit  exchanges  at  the  reduced  sales  charge
  provided   there   is  a  secondary  market  maintained  by  the  Sponsor  in
  both  the  Units  of  this  series  and  units  of  the  applicable  Exchange
  Trust  and  there  are  units  of  the  applicable  Exchange  Trust available
  for  sale.  While  the  Sponsor  has  indicated  that  it intends to maintain
  a  market  for  the  units  of  the  respective  Trusts,  there is no obliga-
  tion  on  its  part  to  maintain  such  a  market.  Therefore,  there  is no
  assurance  that  a  market  for  units  will  in fact exist on any given date
  at  which  a  Unitholder  wishes  to  sell  his  Units  of  this  series  and
  thus   there   is   no   assurance   that   the   Exchange   Option  will  be
  available  to  a  Unitholder.  Exchanges  will  be  effected  in  whole units
  only.   Any   excess   proceeds   from   Unitholders'   units  being  surren-
  dered  will  be  returned.  Unitholders  will  be  permitted  to  advance new
  money in order to complete an exchange.
       An   exchange   of   units   pursuant   to   the  Exchange  Option  will
  normally   constitute   a   "taxable   event"   under   the   Code,  i.e.,  a
  Unitholder  will  recognize  a  tax  gain  or loss which will be of a capital
  or   ordinary   nature   depending   upon   among  other  things  the  length
  of   time   such   Unitholder   has   held  the  Units.  However,  under  the
  position   taken   by   the   Internal  Revenue  Service  in  Revenue  Ruling
  81-204   (relating   to   the  exchange  of  pools  of  residential  mortgage
  loans   by   several   savings   and   loan  associations),  an  exchange  of
  units   for   units   of   any   other  similar  series  of  the  PaineWebber
  Municipal   Bond   Trust,   may   not  constitute  a  taxable  event  if  the
  units  exchanged  do  not  differ  materially  either  in  kind  or in extent
  from   each  other  or  if  the  exchange  has  no  significant  economic  or
  business   purpose   or   utility   apart   from  the  anticipated  tax  con-
  sequences.   Unitholders   are   advised  to  consult  their  own  tax  advi-
  sors   as   to   the   tax   consequences   of   exchanging  units  in  their
  particular case.
       The   Sponsor  reserves  the  right  to  modify,  suspend  or  terminate
  this  plan  at  any  time  without  further  notice  to  Unitholders.  In the
  event   the  Exchange  Option  is  not  available  to  a  Unitholder  at  the
  time   he   wishes  to  exercise  it,  the  Unitholder  will  be  immediately
  notified  and  no  action  will  be  taken  with respect to his Units without
  further instruction from the Unitholder.
       To  exercise  the  Exchange  Option,  a  Unitholder  should  notify  the
 <PAGE>
  Sponsor   of   his  desire  to  exercise  the  Exchange  Option  and  to  use
  the  proceeds  from  the  sale  of  his  Units  of  this  series  to purchase
  units   of   one   or   more   of  the  Exchange  Trusts.  If  units  of  the
  applicable  outstanding  series  of  the  Exchange  Trust  are  at  that time
  available  for  sale,  and  if  such  units may lawfully be sold in the state
  in   which  the  Unitholder  is  resident,  the  Unitholder  may  select  the
  series  or  group  of  series  for  which  he  desires  his  investment to be
  exchanged.   The   Unitholder  will  be  provided  with  a  current  prospec-
  tus   or   prospectuses  relating  to  each  series  in  which  he  indicates
  interest.
       The   exchange   transaction   will  operate  in  a  manner  essentially
  identical   to   any  secondary  market  transaction,  i.e.,  Units  will  be
  repurchased  at  a  price  based  on  the  aggregate  bid  price  per Unit of
  the  securities  in  the  portfolio  of  the  Trust.  Units  of  the Exchange
  Trust,   however,  will  be  sold  to  the  Unitholder  at  a  reduced  sales
  charge.   Units   sold  under  the  Exchange  Option  will  be  sold  at  the
  bid   prices  per  unit  of  the  underlying  securities  in  the  particular
  portfolio   involved   plus   a  fixed  charge  of  $15  per  unit.  Exchange
  transactions  will  be  effected  only  in  whole  units;  thus, any proceeds
  not  used  to  acquire  whole  units  will  be  paid  to the selling Unithol-
  der.
       For   example,  assume  that  a  Unitholder,  who  has  three  units  of
  a  trust  with  a  current  price  of  $1,030  per  unit  based  on  the  bid
  prices   of  the  underlying  securities,  desires  to  sell  his  units  and
  seeks   to   exchange   the   proceeds   for   units   of   a  series  of  an
  Exchange  Trust  with  a  current  price  of  $890  per  unit  based  on  the
  bid  prices  of  the  underlying  securities.  In  this  example,  which does
  not   contemplate   rounding   up  to  the  next  highest  number  of  units,
  the   proceeds   from   the   Unitholder's   units   will  aggregate  $3,090.
  Since   only   whole   units   of   an   Exchange   Trust  may  be  purchased
  under   the  Exchange  Option,  the  Unitholder  would  be  able  to  acquire
  three  units  in  the  Exchange  Trust  for  a  total  cost of $2,715 ($2,670
  for   the   units   and  $45  for  the  sales  charge).  The  remaining  $375
  would be returned to the Unitholder in cash.
                                CONVERSION OPTION
       Owners   of   units  of  any  registered  unit  investment  trust  spon-
  sored  by  others  which  was  initially  offered  at  a  maximum  applicable
  sales   charge  of  at  least  3.0%  (  a  Conversion  Trust)  may  elect  to
  apply   the   cash  proceeds  of  the  sale  or  redemption  of  those  units
  directly   to   acquire   available   units   of  any  Exchange  Trust  at  a
  reduced  sales  charge  of  $15  per  Unit,  per  100  Units  in  the case of
  Exchange   Trusts   having   a  Unit  price  of  approximately  $10,  or  per
  1,000  Units  in  the  case  of  Exchange  Trusts  having  a  Unit  price  of
  approximately   $1,  subject  to  the  terms  and  conditions  applicable  to
  the   Exchange   Option   (except   that  no  secondary  market  is  required
  for   Conversion   Trust   units).   To   exercise  this  option,  the  owner
  should  notify  his  retail  broker.  He  will  be  given  a  prospectus  for
  each  series  in  which  he  indicates  interest  and  for  which  units  are
  available.  The  dealer  must  sell  or  redeem  the  units  of  the  Conver-
  sion  Trust.  Any  dealer  other  than  PaineWebber  must  certify  that  the
 <PAGE>
  purchase   of  units  of  the  Exchange  Trust  is  being  made  pursuant  to
  and  is  eligible  for  the  Conversion  Option.  The dealer will be entitled
  to   two-thirds   of   the  applicable  reduced  sales  charge.  The  Sponsor
  reserves   the   right   to  modify,  suspend  or  terminate  the  Conversion
  Option   at   any  time  without  further  notice,  including  the  right  to
  increase  the  reduced  sales  charge  applicable  to  this  option  (but not
  in  excess  of  $5  more  per  Unit,  per  100  Units  or per 1,000 Units, as
  applicable   than   the   corresponding   fee  then  being  charged  for  the
  Exchange   Option).   For   a  description  of  the  tax  consequences  of  a
  conversion    reference    is   made   to   the   Exchange   Option   section
  herein.
                              EXPENSES OF THE TRUST
       The  cost  of  the  preparation  and  printing  of the Certificates, the
  Indenture  and  this  Prospectus,  the  initial  fees  of the Trustee and the
  Trustee's   counsel,   the  Evaluator's  fees  during  the  initial  offering
  period,   advertising   expenses   and   expenses  incurred  in  establishing
  the  Trust,  including  legal  and  auditing  fees,  are  paid by the Sponsor
  and   not   by   the  Trust.  The  Sponsor  will  receive  no  fee  from  the
  Trust for its services as Sponsor.
       The   Sponsor's   fee,  deducted  only  in  trusts  where  the  Date  of
  Deposit   is   on   or   after   November  30,  1982,  which  is  earned  for
  portfolio   supervisory   services,   is   based   upon  the  aggregate  face
  amount   of   Bonds   in   the   Trust   at  the  beginning  of  each  annual
  period.   The   Sponsor's  fee,  which  is  not  to  exceed  the  amount  set
  forth  under  "Essential  Information"  in  Part  A,  may  exceed  the actual
  costs  of  providing  portfolio  supervisory  services  for  this  Trust, but
  at  no  time  will  the  total  amount  the  Sponsor  receives  for portfolio
  supervisory   services   rendered   to  all  series  of  the  Municipal  Bond
  Trust   in   any   calendar   year   exceed  the  aggregate  cost  to  it  of
  supplying such services in such year.
       For  services  performed  under  the  Indenture,  the  Trustee  will  be
  paid   by   the  Trust  at  the  rate  per  $1,000  of  principal  amount  of
  Securities   in   the  Trust  set  forth  under  "Essential  Information"  in
  Part   A.   Such   compensation   will  be  computed  monthly,  quarterly  or
  semi-annually   (depending   on  available  plans  of  distribution)  on  the
  basis  of  the  greatest  principal  amount  of  the  Securities in the Trust
  at   any  time  during  the  preceding  monthly  or  semi-annual  period.  In
  no  event  will  the  Trustee  be  paid  less  than  $2,000  in any one year.
  The   Evaluator's   fee   for  each  daily  evaluation  is  set  forth  under
  "Essential  Information"  in  Part  A.  The  fees  of  the  Evaluator will be
  payable  by  the  Trust.  See  "Essential  Information"  in  Part  A  for the
  estimated   annual   fees   and   expenses   per   Unit   under  the  various
  optional interest distribution plans.
       The   Sponsor's   fee   is   payable   annually,   Trustee's   fees  are
  payable   monthly,   quarterly   and   semi-annually   (depending  on  avail-
  able   plans   of   distribution)   and  the  Evaluator's  fees  are  payable
  monthly   on   or   before   each   Distribution   Date   from  the  Interest
  Account,  to  the  extent  funds  are  available,  then  from  the  Principal
  Account.  Any  of  such  fees  may  be  increased  without  approval  of  the
  Unitholders   by   an  amount  not  exceeding  a  proportionate  increase  in
 <PAGE>
  the   category   entitled   "All   Services   Less   Rent"  in  the  Consumer
  Price Index published by the United States Department of Labor.
       In  addition  to  the  above,  the  following  charges  are  or  may  be
  incurred  by  the  Trust  and  paid  from  the  Interest  Account, or, to the
  extent   funds  are  not  available  in  such  Account,  from  the  Principal
  Account:   (1)   fees   for  the  Trustee  for  extraordinary  services;  (2)
  expenses   of  the  Trustee  (including  legal  and  auditing  expenses)  and
  of   counsel;   (3)   various   governmental   charges;   (4)   expenses  and
  costs  of  any  action  taken  by  the  Trustee  to  protect  the  Trust  and
  the  rights  and  interests  of  the  Unitholders; (5) indemnification of the
  Trustee  for  any  loss,  liabilities  or  expenses  incurred  by  it  in the
  administration   of  the  Trust  without  negligence,  bad  faith  or  wilful
  misconduct   on   its   part;   and   (6)  expenses  incurred  in  contacting
  Unitholders   upon   termination   of   the  Trust.  The  fees  and  expenses
  set  forth  above  are  payable  out  of  the  Trust  and  when  unpaid  will
  be secured by a lien on the Trust.
       The   accounts   of   certain  Trusts  may  be  audited  not  less  than
  annually   by   independent   public   accountants   selected  by  the  Spon-
  sor.  The  expenses  of  the  audit  shall  be  an  expense  of the Trust. So
  long   as   the   Sponsor   maintains   a   secondary  market,  Sponsor  will
  bear   any   audit   expense  which  exceeds  50  cents  per  Unit.  Unithol-
  ders   covered  by  the  audit  (if  any)  during  the  year  may  receive  a
  copy of the audited financials upon request.
                           DESCRIPTION OF CERTIFICATES
       Ownership   of   Units   is   evidenced   by   registered  Certificates,
  executed   by   the   Trustee   and  the  Sponsor,  issued  in  denominations
  of   one   Unit   or   any   integral  multiple  thereof.  A  Unitholder  may
  transfer  its  Certificate  by  presenting it to the Trustee at its corporate
  trust   office.   Such  Certificate  must  be  properly  endorsed  or  accom-
  panied   by   a  written  instrument  or  instruments  of  transfer  executed
  by  the  Unitholder  or  its  duly  authorized  attorney.  A  Unitholder  may
  be   required   to  pay  $2.00  per  Certificate  transferred  to  cover  the
  Trustee's  costs  in  implementing  such  transfer  and  to  pay  any  tax or
  other   governmental   charge   that   may  be  imposed  in  connection  with
  any  such  transfer.  The  Trustee  is  required  to  execute  and  deliver a
  new   Certificate   in   exchange   and   substitution  for  any  Certificate
  mutilated,   destroyed,   stolen   or   lost,  if  and  when  the  Unitholder
  furnishes   the   Trustee   with   proper   identification  and  satisfactory
  indemnity,   and   pays   such   expenses   as  the  Trustee  may  reasonably
  incur.   Any   mutilated   Certificate  must  be  presented  to  the  Trustee
  before any substitute Certificate will be issued.
                            STATEMENTS TO UNITHOLDERS
       With  each  distribution  from  the  Interest  and  Principal  Accounts,
  the   Trustee   will   furnish  each  Unitholder  with  a  statement  setting
  forth   the   amount   being  distributed  from  each  Account  expressed  as
  a dollar amount per Unit.
       Promptly  after  the  end  of  each  calendar  year,  the  Trustee  will
  furnish   to   each   person  who  at  any  time  during  the  calendar  year
  was a registered Unitholder a statement setting forth:
 <PAGE>
       1. As to the Interest Account:
       (a)   the  amount  of  interest  received  on  the  Securities  and  the
  percentage  of  such  amount  by  states  and  territories  in
  which the issuers of the Bonds are located;
       (b)   the   amount   paid   from   the   Interest  Account  representing
  accrued interest for any Certificates redeemed;
       (c)   the   deductions   from   the   Interest   Account  for  fees  and
  expenses  of  the  Trustee,  the  Sponsor  and  the  Evaluator  or for
    other various fees, charges or expenses relating to the Trust;
       (d)   the   deductions  from  the  Interest  Account  for  payment  into
  the Reserve Account; and
       (e)   the   net   amount   remaining  after  such  payments  and  deduc-
  tions  expressed  as  a  total  dollar  amount  outstanding  on  the
  last business day of such calendar year.
       2. As to the Principal Account:
       (a)  the  dates  of  the  redemption,  sale  or  maturity  of any of the
  Securities   and   the  net  proceeds  received  therefrom,
  excluding any portion credited to the Interest Account;
       (b)   the   amount   paid   from   the  Principal  Account  representing
  the principal of any Certificates redeemed;
       (c)   the   deductions   from   the   Principal  Account  for  fees  and
  expenses  of  the  Trustee,  the  Sponsor  and  the  Evaluator  or for
    other various fees, charges or expenses relating to the Trust;
       (d)   the  deductions  from  the  Principal  Account  for  payment  into
  the Reserve Account; and
       (e)   the   net   amount   remaining  after  such  payments  and  deduc-
  tions  expressed  as  a  total  dollar  amount  outstanding  on  the
  last business day of such calendar year.
       3. The following information:
       (a)  a  list  of  the  Securities  as  of  the last business day of such
  calendar year;
       (b)   the   number  of  Units  outstanding  on  the  last  business  day
  of such calendar year;
       (c)   the  Unit  Value  based  on  the  last  evaluation  of  the  Trust
  made  on  the  last  business  day  during  such  calendar  year;
  and
       (d)   the   amounts  actually  distributed  during  such  calendar  year
  from  the  Interest  and  Principal  Accounts,  separately  stated,
  expressed   both   as   total  dollar  amounts  and  as  dollar  amounts  per
  Unit outstanding on the Record Dates for such distributions.
                         REDEMPTION OF UNITS BY TRUSTEE
       A  Unitholder  who  wishes  to  dispose  of  its  Units  should  inquire
  through   its   broker  as  to  the  current  market  price  for  such  Units
  prior  to  making  a  tender  for  redemption  to  the  Trustee  in  order to
  determine   if   there   is  a  market  for  Units  in  excess  of  the  then
  current   Redemption   Value   or   Sponsor's  Repurchase  Price.  After  the
  initial  offering  period  the  Redemption  Value  will  be  the  same as the
  Sponsor's Repurchase Price.
 <PAGE>
       During   the   period   in  which  the  Sponsor  maintains  a  secondary
  market   for   Units   at   the   Sponsor's  Repurchase  Price,  the  Sponsor
  has   agreed   to   repurchase   any   Unit   presented  for  tender  to  the
  Trustee   for  redemption  no  later  than  the  close  of  business  on  the
  second business day following such presentation.
       The  Trustee  is  irrevocably  authorized  in its discretion, in lieu of
  redeeming   Units   presented   for   tender  at  the  redemption  value,  to
  sell  such  Units  in  the  over-the-counter  market  for  the  account  of a
  tendering   Unitholder   at  prices  which  will  return  to  the  Unitholder
  amounts   in   cash,   net   after   brokerage  commissions,  transfer  taxes
  and   other   charges,  equal  to  or  in  excess  of  the  Redemption  Value
  for  such  Units.  In  the  event  of  any  such  sale  the  Trustee will pay
  the   net   proceeds   thereof   to  the  Unitholder  on  the  day  he  would
  otherwise be entitled to receive payment of the Redemption Value.
       One   or   more   Units   represented   by  a  Certificate  may  be  re-
  deemed   at   the  Redemption  Value  upon  tender  of  such  Certificate  to
  the   Trustee   at   its   corporate   trust  office,  properly  endorsed  or
  accompanied  by  a  written  instrument  of  transfer  in  form  satisfactory
  to   the   Trustee,   and  executed  by  the  Unitholder  or  its  authorized
  attorney.   A   Unitholder  may  tender  its  Units  for  redemption  at  any
  time  after  the  settlement  date  for  purchase,  whether  or  not  it  has
  received   a  definitive  Certificate.  The  Redemption  Value  per  Unit  is
  calculated  by  dividing  the  current  bid  prices for the Securities in the
  Trust   (see   "Evaluation   of   the   Trust")   plus   any   money  in  the
  Principal   Account   other   than   money   required   to   redeem  tendered
  Units,   by   the   number   of   Units  outstanding,  plus  a  proportionate
  share   of   accrued  interest  and  undistributed  interest  income  on  the
  Securities  determined  to  the  day  of  tender.  There  is  no sales charge
  incurred   when   a   Unitholder   tenders  his  Units  to  the  Trustee  for
  redemption.   Subject   to   the  payment  of  any  applicable  tax  or  gov-
  ernmental   charges,   the   Redemption   Value  of  Units  redeemed  by  the
  Trustee  will  be  paid  on  the  seventh  calendar  day  following  the  day
  of   tender.   If   such   day   of  payment  is  not  a  business  day,  the
  Redemption   Value   will   be   paid   on   the  first  business  day  prior
  thereto.
       The  Trustee  may,  in  its  discretion,  and  will  when so directed by
  the   Sponsor,  suspend  the  right  of  redemption,  or  postpone  the  date
  of   payment   of   the  Redemption  Value,  for  more  than  seven  calendar
  days   following   the  day  of  tender  for  any  period  during  which  the
  New   York   Stock   Exchange,   Inc.   is  closed  other  than  for  weekend
  and  holiday  closings;  or  for  any  period  during  which  the  Securities
  and   Exchange   Commission   determines   that   trading  on  the  New  York
  Stock  Exchange,  Inc.  is  restricted  or  for  any  period  during which an
  emergency  exists  as  a  result  of  which  disposal  or  evaluation  of the
  Securities  is  not  reasonably  practicable;  or  for  such  other period as
  the   Securities   and   Exchange   Commission   may   by  order  permit  for
  the   protection   of   Unitholders.   The  Trustee  is  not  liable  to  any
  person   or   in   any   way  for  any  loss  or  damages  which  may  result
  from any such suspension or postponement.
       Any   amounts   paid   on   redemption  representing  interest  will  be
  withdrawn   from   the   Interest  Account  to  the  extent  that  funds  are
 <PAGE>
  available   for   such   purpose.   All  other  amounts  paid  on  redemption
  will   be   withdrawn   from   the   Principal   Account.   The   Trustee  is
  empowered   to   sell  Securities  out  of  the  Trust  as  selected  by  the
  Sponsor   in   order   to   make   funds  available  for  the  redemption  of
  Certificates,  and,  to  the  extent  Securities  are  sold for such purpose,
  the  size  and  diversity  of  the  Trust  will  be  reduced.  Such sales may
  be   required  at  a  time  when  Securities  would  not  otherwise  be  sold
  and  may  result  in  lower  prices  than  might  otherwise  be  realized. In
  addition,   because   of  the  minimum  principal  amount  in  which  Securi-
  ties   may   be  required  to  be  sold,  the  proceeds  of  such  sales  may
  exceed   the   amount   necessary   for   payment  of  Units  redeemed.  Such
  excess  proceeds  will  be  distributed  pro  rata  to all remaining Unithol-
  ders of record.
                             EVALUATION OF THE TRUST
       The   Evaluator   is  Kenny  S&P  Evaluation  Services,  a  division  of
  Kenny    Information    Systems,   Inc.,   65   Broadway,   New   York,   New
  York 10006.
       The   value  of  the  Trust  is  computed  as  of  the  Evaluation  Time
  shown   under  "Essential  Information"  in  Part  A  (1)  on  each  June  30
  and   December   31  (or  the  last  business  day  prior  thereto),  (2)  on
  each   business  day  as  long  as  the  Sponsor  is  maintaining  a  bid  in
  the  secondary  market,  (3)  on  the  day  on  which  any  Unit  is tendered
  for  redemption  and  (4)  on  any  other  day  desired  by  the  Sponsor  or
  the Trustee, by adding:
       1.  The  aggregate  value  of  Securities  in  the  Trust, as determined
  by the Evaluator:
       (a) on the basis of current bid prices for the Securities,
       (b)  on  the  basis  of  current  bid  prices  for  comparable bonds, if
  bid prices are not available for any of the Securities,
       (c)  by  determining  the  value  of  the  Securities on the bid side of
  the market by appraisal, or
       (d) by any combination of the above;
       2.   Money  on  hand  in  the  Trust,  other  than  money  deposited  to
  purchase   Securities   or   money   credited   to   the   Principal  Account
  which is required to redeem tendered Units; and
       3.  Accrued  but  unpaid  interest  on  the  Securities  at the close of
  business on the date of such Evaluation.
       The   Trustee   will   deduct   from   the   resulting  figure:  amounts
  representing   any   applicable   taxes   or   governmental  charges  payable
  by  the  Trust  for  the  purpose  of  making  an  addition  to  the  Reserve
  Account;   amounts   representing   estimated   accrued   expenses   of   the
  Trust;   amounts  representing  unpaid  fees  of  the  Trustee,  the  Sponsor
  and  the  Evaluator;  and  cash  held  for  distribution  to  Unitholders  of
  record   as   of  the  business  day  prior  to  the  Evaluation  being  made
  on the days or dates set forth above.
       For  the  purpose  of  the  redemption  of  Units,  the  value  per Unit
  is   computed   by   the   Trustee  by  dividing  the  result  of  the  above
  computation   by   the   total  number  of  Units  outstanding  on  the  date
  of such Evaluation.

               COMPARISON OF PUBLIC OFFERING PRICE AND REDEMPTION
                                      VALUE
       While   the   Public   Offering   Price  of  Units  during  the  initial
  offering   period  is  determined  on  the  basis  of  the  current  offering
  prices  of  the  Securities,  the  Public  Offering  Price  of  Units  in the
  secondary   market   and   the   Redemption   Value   is  determined  on  the
  basis  of  the  current  bid  prices  of  such  Securities.  On  the  date of
  the  "Essential  Information"  page,  the  Public  Offering  Price  per  Unit
  (which   figure   includes   the   sales   charge)  exceeded  the  Redemption
  Value   by   the   amount   shown   under  "Essential  Information"  in  Part
  A.   The   difference   between   the   bid   and   offering  prices  of  the
  Securities  is  expected  to  average  1-1/2%  to  2%  of  principal  amount.
  This   difference   may   vary   between  3%  or  more  of  principal  amount
  for  inactively  traded  Securities  and  as little as 1/2 of 1% for actively
  traded  Securities.  For  this  reason  and  others,  including the fact that
  the   Public   Offering   Price   includes   the  sales  charge,  the  amount
  realized  by  a  Unitholder  upon  redemption  of  Units  may  be  less  than
  the price paid by the Unitholder for such Units.
                        SUPERVISION OF TRUST INVESTMENTS
       The   acquisition  by  the  Trust  of  any  securities  other  than  the
  Securities   initially   deposited   is  prohibited  by  the  Indenture.  The
  Sponsor   may   direct   the   Trustee  to  sell  or  liquidate  any  of  the
  Securities   upon   the   happening   of   any   of   the   following  events
  (except  for  the  limited  right  to  replace  securities  in  the case of a
  fail):
       1.  Default  by  an  issuer  in  the payment of principal of or interest
  on   such   Securities,   or   any  other  outstanding  obligations  of  such
  issuer, when due and payable,
       2.  Institution  of  legal  proceedings  seeking  to  restrain or enjoin
  the payment of any of the Securities or attacking their validity,
       3.   A   breach   of  a  covenant  or  warranty  which  could  adversely
  affect the payment of debt service on the Securities,
       4.   In  the  case  of  revenue  bonds,  if  the  revenues,  based  upon
  official  reports,  fall  substantially  below  the  estimated  revenues cal-
  culated   to   be   necessary  to  pay  principal  of  and  interest  on  the
  Bonds,
       5.   A  decline  in  market  price,  or  such  other  market  or  credit
  factor,   as   in  the  opinion  of  the  Sponsor  would  make  retention  of
  any of the Securities detrimental to the Unitholders, or
       6.  In  the  event  that  any  of  the  Bonds  are  the  subject  of  an
  advance refunding.
       In  addition,  if  a  default in the payment of principal of or interest
  on  any  of  the  Securities  occurs  and  the  Sponsor fails to instruct the
  Trustee   to   sell   or  hold  such  Securities  within  thirty  days  after
  notification   by   the   Trustee   to  the  Sponsor  of  such  default,  the
  Indenture  provides  that  the  Trustee  will  sell  the defaulted Securities
  promptly.  The  Trustee  will  not  be  liable  or  responsible  in  any  way
  for  depreciation  or  loss  incurred  by  reason  of  any  sale  made  by it
  either   pursuant   to  a  direction  of  the  Sponsor  or  by  reason  of  a
  failure of the Sponsor to give any such direction.
 <PAGE>
       The   Sponsor  is  required  to  instruct  the  Trustee  to  reject  any
  offer   made   by   an   issuer   of   any   of   the   Bonds  to  issue  new
  obligations   in   exchange   and   substitution   for   any   of  the  Bonds
  pursuant   to   a   refunding  or  refinancing  plan;  however,  the  Sponsor
  may  instruct  the  Trustee  to  accept  or  reject  such an offer or to take
  any   other   action  with  respect  thereto  as  the  Sponsor  deems  proper
  if  the  issuer  is  in  default with respect to the Securities or the issuer
  will,   in  the  written  opinion  of  the  Sponsor,  probably  default  with
  respect to the Bonds in the reasonably foreseeable future.
       Any  obligations  received  by  the  Trust  in  the  event  of  such  an
  exchange   or   substitution  will  be  held  by  the  Trustee  and  will  be
  subject   to   the  terms  and  conditions  of  the  Indenture  to  the  same
  extent  as  the  Securities  originally  deposited.  Within  five  days after
  any   exchange   and   deposit,   notice  of  such  will  be  mailed  by  the
  Trustee  to  each  registered  Unitholder,  which  identifies  the Securities
  eliminated and the Securities substituted.
                           ADMINISTRATION OF THE TRUST
       Records   and   Accounts:   Pursuant   to  the  Indenture,  the  Trustee
  is   required   to   keep   proper   books  of  record  and  account  of  all
  transactions  relating  to  the  Trust  at  its  office.  Such  records  will
  include   the   name   and  address  of  every  Unitholder,  a  list  of  the
  Certificate   numbers   and   the   number   of  Units  of  each  Certificate
  issued   to   Unitholders.   The   Trustee   is   also  required  to  keep  a
  certified  copy  or  duplicate  original  of the Indenture and a current list
  of  Securities  held  in  the  Trust on file at its office which will be open
  to inspection by any Unitholder during usual business hours.
       The  Trustee  is  required  to  make  annual  or  other  reports  as may
  from  time  to  time  be  required  under  any  applicable  state  or Federal
  statute, rule or regulation.
       Successor   Trustee:   Under  the  Indenture,  the  Trustee  may  resign
  and   be   discharged   of   the   Trust   created   by   the   Indenture  by
  executing  a  notice  of  resignation  in  writing  and  filing  it  with the
  Sponsor.  The  resigning  Trustee  must  also  mail  a  copy  of  the  notice
  of  resignation  to  all  Unitholders  then  of  record,  not less than sixty
  days  before  the  effective  resignation  date  specified  in  such  notice.
  Such   resignation  will  become  effective  only  upon  the  appointment  of
  and   the   acceptance   of   the   Trust   by   a   successor  Trustee.  The
  Sponsor,   upon  receiving  notice  of  such  resignation,  is  obligated  to
  appoint a successor Trustee promptly.
       If  within  thirty  days  after  notice  of  resignation  has  been  re-
  ceived   by   the   Sponsor,   no   successor   Trustee  has  been  appointed
  or,   if   appointed,   has  not  accepted  the  appointment,  the  resigning
  Trustee   may   apply   to   a   court  of  competent  jurisdiction  for  the
  appointment   of   a   successor.  In  case  the  Trustee  becomes  incapable
  of  acting  as  such  or  is  adjudged  a  bankrupt  or  is taken over by any
  public   authority,   the   Sponsor   may   discharge  the  Trustee  and  ap-
  point   a   successor  Trustee  as  provided  in  the  Indenture.  Notice  of
  such   discharge   and   appointment  shall  be  mailed  to  each  Unitholder
  by the Sponsor.
       Upon   a   successor   Trustee's   execution  of  a  written  acceptance
 <PAGE>
  of   an  appointment  as  Trustee  for  the  Trust,  such  successor  Trustee
  will   become   vested   with   all   the  rights,  powers,  duties  and  ob-
  ligations of the original Trustee.
       A   successor   Trustee  is  required  to  be  a  corporation  organized
  and   doing  business  under  the  laws  of  the  United  States  or  of  the
  State   of   New   York;  to  be  authorized  under  such  laws  to  exercise
  corporate   trust  powers;  to  have  at  all  times  an  aggregate  capital,
  surplus   and   undivided   profit  of  not  less  than  $5,000,000;  and  to
  have its principal office in New York City.
       Successor   Sponsor:   If   at  any  time  the  Sponsor  shall  fail  to
  undertake   or   perform   or   become   incapable  of  undertaking  or  per-
  forming  any  of  the  duties  which  by  the  terms  of  the  Indenture  are
  required   of   it   to  be  undertaken  or  performed,  or  if  the  Sponsor
  resigns,   the   Trustee   may   either   appoint   a  successor  Sponsor  or
  Sponsors  as  will  be  satisfactory  to  the  Trustee  or  it  may terminate
  the   Indenture   and   liquidate   the  Trust.  Any  successor  Sponsor  may
  be compensated at rates deemed by the Trustee to be reasonable.
       The  dissolution  of  the  Sponsor  or  its  ceasing to exist as a legal
  entity   from,   or   for,   any   cause   whatsoever   will  not  cause  the
  termination   of  the  Indenture  or  the  Trust  unless  the  Trustee  deems
  termination to be in the best interests of Unitholders.
       Successor    Evaluator:   The   Evaluator   may   resign   or   may   be
  removed   by   the   Sponsor   or  the  Trustee,  and  the  Sponsor  and  the
  Trustee   are   to   use   their  best  efforts  to  appoint  a  satisfactory
  successor.   Such   resignation   or   removal  will  become  effective  upon
  the   acceptance   of   appointment   by   a  successor  Evaluator.  If  upon
  resignation   of   the   Evaluator  no  successor  has  accepted  appointment
  within   thirty   days   after  notice  of  resignation,  the  Evaluator  may
  apply  to  a  court  of  competent  jurisdiction  for  the  appointment  of a
  successor   Evaluator.   Notice   of   such   resignation   or   removal  and
  appointment will be mailed by the Trustee to each Unitholder.
                            LIMITATION OF LIABILITIES
       The   Sponsor:   The  Indenture  provides  that  the  Sponsor  will  not
  be  liable  to  the  Trustee,  the  Trust  or  the Unitholders for taking any
  action  or  for  refraining  from  taking  any  action  made in good faith or
  for  errors  in  judgment,  but  will  be  liable  only  for  its  own wilful
  misfeasance,   bad  faith,  gross  negligence  or  wilful  disregard  of  its
  duties.  The  Sponsor  will  not  be  liable  or  responsible  in any way for
  depreciation  or  loss  incurred  by  reason  of  the  sale of any Securities
  in the Trust.
       The  Trustee:  The  Indenture  provides  that  the  Trustee  will not be
  liable   for  any  action  taken  in  good  faith  in  reliance  on  properly
  executed   documents   or  for  the  disposition  of  moneys,  Securities  or
  Certificates,  except  by  reason  of  its  own  gross  negligence, bad faith
  or  wilful  misconduct,  nor  will  the  Trustee  be liable or responsible in
  any  way  for  depreciation  or  loss  incurred  by  reason  of  the  sale by
  the  Trustee  of  any  Securities  in  the Trust. In the event of the failure
  of  the  Sponsor  to  act,  the  Trustee  may  act and will not be liable for
  any  such  action  taken  by  it  in  good  faith.  The  Trustee  will not be
  personally   liable   for   any   taxes   or   other   governmental   charges
 <PAGE>
  imposed   upon  or  in  respect  of  the  Securities  or  upon  the  interest
  thereon  or  upon  it  as  Trustee  or  upon  or  in  respect  of  the  Trust
  which   the   Trustee   may   be   required  to  pay  under  any  present  or
  future  law  of  the  United  States  of  America  or  of  any  other  taxing
  authority   having   jurisdiction.   In   addition,  the  Indenture  contains
  other  customary  provisions  limiting  the  liability  of  the  Trustee. The
  Trustee   will   be  indemnified  and  held  harmless  against  any  loss  or
  liability  accruing  to  it  without  negligence,  bad  faith  or wilful mis-
  conduct   on   its   part,   arising   out  of  or  in  connection  with  its
  acceptance   or   administration  of  the  Trust,  including  the  costs  and
  expenses   (including   counsel   fees)   of  defending  itself  against  any
  claim of liability.
 <PAGE>
       The   Evaluator:   The   Trustee,  Sponsor,  and  Unitholders  may  rely
  on   any   evaluation   furnished   by   the   Evaluator  and  will  have  no
  responsibility   for  the  accuracy  thereof.  The  Indenture  provides  that
  the  determinations  made  by  the  Evaluator  will  be  made  in  good faith
  upon   the   basis  of  the  best  information  available  to  it;  provided,
  however,  that  the  Evaluator  will  be  under  no liability to the Trustee,
  Sponsor   or   Unitholders  for  errors  in  judgment,  but  will  be  liable
  only   for   its  gross  negligence,  lack  of  good  faith  or  wilful  mis-
  conduct.
                           AMENDMENT OF THE INDENTURE
       The   Indenture   may   be   amended   by  the  Trustee  and  the  Spon-
  sor   without   the   consent   of   any  of  the  Unitholders  to  cure  any
  ambiguity   or   to   correct  or  supplement  any  provision  thereof  which
  may   be   defective  or  inconsistent  or  to  make  such  other  provisions
  as  will  not  adversely  affect  the  interest of the Unitholders; provided,
  however,  that  after  the  deposit  of  the  Securities  the  Indenture  may
  not   be   amended   to  increase  the  number  of  Units  issued  thereunder
  or  to  permit  the  deposit  or acquisition of securities either in addition
  to  or  in  substitution  for  any  of  the Securities initially deposited in
  the  Trust,  except  for  the  substitution  of  certain refunding securities
  for   the  Securities.  The  Trustee  will  promptly  notify  Unitholders  of
  the substance of any such amendment.
                              RIGHTS OF UNITHOLDERS
       A   Unitholder   may   at   any  time  tender  his  Certificate  to  the
  Trustee for redemption.
       The   death  or  incapacity  of  any  Unitholder  will  not  operate  to
  terminate  the  Trust  nor  entitle  his  legal  representatives  or heirs to
  claim   an   accounting   or   to  take  any  action  or  proceeding  in  any
  court for a partition or winding up of the Trust.
       No  Unitholder  will  have  the  right  to  vote  concerning  the Trust,
  except   with   respect   to  termination,  or  in  any  manner  control  the
  operation   and   management   of   the   Trust,  nor  shall  any  Unitholder
  ever  be  liable  to  any  other  person  by  reason  of  any action taken by
  the Sponsor or the Trustee.
                            TERMINATION OF THE TRUST
       The   Indenture   provides  that  the  Trust  will  terminate  upon  the
  maturity,   redemption,  sale  or  other  disposition  of  the  last  of  the
  Securities  held  in  the  Trust.  If  the  value  of  the  Trust as shown by
  any  evaluation  is  less  than  twenty  per  cent  (20%)  of  the  par value
  of  the  Securities  originally  deposited  in  the  Trust,  the  Trustee may
  in  its  discretion,  and  will  when  so  directed  by  the  Sponsor, termi-
  nate  the  Trust.  The  Trust  may  also  be  terminated  at  any time by the
  written   consent  of  100%  of  the  Unitholders  or  by  the  Trustee  upon
  the  resignation  or  removal  of  the  Sponsor  if  the  Trustee  determines
  termination  to  be  in  the  best  interest  of the Unitholders. In no event
  will the Trust continue beyond the Mandatory Termination Date.
       Upon  termination,  the  Trustee  will  sell  the  Securities  then held
  in   the  Trust  and  credit  the  moneys  derived  from  such  sale  to  the
 <PAGE>
  Principal   Account   and  the  Interest  Account.  The  Trustee  will  then,
  after   deduction  of  any  fees  and  expenses  of  the  Trust  and  payment
  into  the  Reserve  Account  of  any  amount  required  for  taxes  or  other
  governmental   charges   that   may  be  payable  by  the  Trust,  distribute
  to  each  Unitholder,  upon  surrender  for  cancellation  of his Certificate
  after   due   notice   of   such  termination,  such  Unitholder's  pro  rata
  share  in  the  Interest  and  Principal  Accounts.  The  sale  of Securities
  in   the   Trust   upon  termination  may  result  in  a  lower  amount  than
  might  otherwise  be  realized  if  such  sale  were  not  required  at  such
  time.   For   this   reason,   among   others,   the  amount  realized  by  a
  Unitholder   upon   termination   may  be  less  than  the  principal  amount
  of Securities represented by the Units held by such Unitholder.

                                  BOND RATINGS*
  Standard & Poor's Corporation
       A   Standard   &   Poor's  corporate  or  municipal  bond  rating  is  a
  current   assessment   of   the   creditworthiness   of   an   obligor   with
 <PAGE>
  respect  to  a  specific  debt  obligation.  This  assessment  of  creditwor-
  thiness   may   take   into   consideration   obligors  such  as  guarantors,
  insurers, or lessees.
       The  bond  rating  is  not  a  recommendation  to  purchase  or  sell  a
  security, inasmuch as it does not comment as to market price.
       The   ratings   are   based   on   current   information   furnished  to
  Standard   &   Poor's   by  the  issuer  and  obtained  by  Standard  &  Poor
  's   from   other   sources   it  considers  reliable.  The  ratings  may  be
  changed,   suspended   or   withdrawn   as   a   result  of  changes  in,  or
  unavailability of, such information.
       The   ratings   are   based,   in  varying  degrees,  on  the  following
  considerations:
       I.  Likelihood  of  default  capacity  and  willingness  of  the obligor
  as  to  the  timely  payment  of  interest  and  repayment  of  principal  in
  accordance with the terms of the obligation, and
       II. Nature of and provisions of the obligation,
       III.  Protection  afforded  by,  and  relative  position of, the obliga-
  tion  in  the  event  of  bankruptcy,  reorganization  or  other  arrangement
  under   the   laws   of   bankruptcy  and  other  laws  affecting  creditors'
  rights.
       AAA--This  is  the  highest  rating  assigned  by  Standard  &  Poor  's
  to   a  debt  obligation  and  indicates  an  extremely  strong  capacity  to
  pay principal and interest.
       AA--Bonds   rated   AA   also   qualify  as  high-quality  debt  obliga-
  tions.  Capacity  to  pay  principal  and  interest  is  very  strong, and in
  the  majority  of  instances  they  differ  from  AAA  issues  only  in small
  degree.
       A--Bonds   rated   A  have  a  strong  capacity  to  pay  principal  and
  interest,    although   they   are   somewhat   more   susceptible   to   the
  adverse   effects   of   changes   in   circumstances   and   economic   con-
  ditions.
       BBB--Bonds    rated   BBB   are   regarded   as   having   an   adequate
  capacity  to  pay  principal  and  interest.  Whereas  they  normally exhibit
  adequate    protection    parameters,    adverse   economic   conditions   or
  changing   circumstances   are   more   likely   to   lead   to   a  weakened
  capacity   to   pay  principal  and  interest  for  bonds  in  this  category
  than for bonds in the A category.
       BB,  B,  CCC,  CC--Debt  rated  BB,  B,  CCC  and  CC  is  regarded,  on
  balance,   as   predominantly   speculative   with  respect  to  capacity  to
  pay  interest  and  repay  principal  in  accordance  with  the  terms of the
  obligation.   BB   indicated   the   lowest  degree  of  speculation  and  CC
  the  highest  degree  of  speculation.  While  such  debt  will  likely  have
  some   quality  and  protective  characteristics,  these  are  outweighed  by
  large uncertainties or major risk exposures to adverse conditions.
       C--The   rating   C   is   reserved   for   income  bonds  on  which  no
  interest is being paid.
       D--Debt   rated  D  is  in  default,  and  payment  of  interest  and/or
  repayment of principal in arrears.
       PLUS   (+)   or   MINUS   (-):  To  provide  more  detailed  indications
  of  credit  quality,  the  ratings  from  "AA"  to  "BB"  may  be modified by
  the   addition   of   a   plus  or  minus  sign  to  show  relative  standing
 <PAGE>
  within the major rating categories.
       PROVISIONAL    RATINGS:    The    letter    "p"   following   a   rating
  indicates  the  rating  is  provisional.  A  provisional  rating  assumes the
  successful   completion  of  the  project  being  financed  by  the  issuance
  of  the  bonds  being  rated  and  indicates  that  payment  of  debt service
  requirements   is   largely   or   entirely  dependent  upon  the  successful
  and   timely   completion   of  the  project.  This  rating,  however,  while
  addressing   credit   quality   subsequent   to  completion,  makes  no  com-
  ment  on  the  likelihood  of,  or  the risk of default upon failure of, such
  completion.   Accordingly,   the  investor  should  exercise  his  own  judg-
  ment with respect to such likelihood and risk.
       *As described by the rating agencies.

  Moody's Investors Service, Inc.
       A  brief  description  of  the  applicable  Moody's  Investors  Service,
  Inc.'s rating symbols and their meanings is as follows:
       Aaa-Bonds   which   are   rated  Aaa  are  judged  to  be  of  the  best
  quality.   They  carry  the  smallest  degree  of  investment  risk  and  are
  generally  referred  to  as  "gilt  edge".  Interest  payments  are protected
  by   a   large  or  by  an  exceptionally  stable  margin  and  principal  is
  secure.   While  the  various  protective  elements  are  likely  to  change,
  such   changes  as  can  be  visualized  are  most  unlikely  to  impair  the
  fundamentally strong position of such issues.
       Aa--Bonds  which  are  rated  Aa  are  judged  to  be  of  high  quality
  by   all   standards.   Together  with  the  Aaa  group  they  comprise  what
  are   generally  known  as  high-grade  bonds.  They  are  rated  lower  than
  the   best   bonds  because  margins  of  protection  may  not  be  as  large
  as  in  Aaa  securities  or  fluctuation  of  protective  elements  may be of
  greater   amplitude   or   there   may   be   other  elements  present  which
  make   the   long-term   risks   appear   somewhat   larger   than   in   Aaa
  securities.
       A--Bonds   which   are   rated   A  possess  many  favorable  investment
  attributes   and   are   to   be   considered   as  upper  medium  grade  ob-
  ligations.  Factors  giving  security  to  principal and interest are consid-
  ered    adequate,   but   elements   may   be   present   which   suggest   a
  susceptibility to impairment sometime in the future.
       Baa-Bonds    which    are   rated   Baa   are   considered   as   medium
  grade  obligations;  i.e.,  they  are  neither  highly  protected  nor poorly
  secured.   Interest   payments   and   principal   security  appear  adequate
  for   the   present  but  certain  protective  elements  may  be  lacking  or
  may   be  characteristically  unreliable  over  any  great  length  of  time.
  Such   bonds   lack   outstanding  investment  characteristics  and  in  fact
  have speculative characteristics as well.
       Ba--Bonds   which   are   rated   Ba  are  judged  to  have  speculative
  elements;   their   future  cannot  be  considered  as  well  assured.  Often
  the   protection   of   interest   and   principal   payments   may  be  very
  moderate   and   thereby   not   well   safeguarded   during  both  good  and
  bad   times   over   the   future.   Uncertainty  of  position  characterizes
  bonds in this class.
       B--Bonds  which  are  rated  B  generally  lack  the  characteristics of
  a   desirable   investment.   Assurance   of   interest  and  principal  pay-
  ments   or   of   maintenance  of  other  terms  of  the  contract  over  any
  long period of time may be small.
       Caa--Bonds   which   are   rated   Caa   are   in  poor  standing.  Such
  issues   may   be   in   default   or   there  may  be  present  elements  of
  danger with respect to principal or interest.
       Ca--Bonds   which   are   rated   Ca  represent  obligations  which  are
  speculative   in  a  high  degree.  Such  issues  are  often  in  default  or
  have other marked shortcomings.
       C--Bonds  which  are  rated  C  are  the  lowest  rated  class  of bonds
  and   issues   so   rated   can   be   regarded   as  having  extremely  poor
  prospects of ever attaining any real investment standing.
       Rating   symbols  may  include  numerical  modifiers  1,  2  or  3.  The
 <PAGE>
  numerical   modifier  1  indicates  that  the  security  ranks  at  the  high
  end,  2  in  the  mid-range,  and  3  nearer  the  low  end  of  the  generic
  category.   These   modifiers  of  rating  symbols  Aa,  A  and  Baa  are  to
  give  investors  a  more  precise  indication  of  relative  debt  quality in
  each of the historically defined categories.
       Conditional   ratings,  indicated  by  "Con"  are  given  to  bonds  for
  which   the  security  depends  upon  the  completion  of  some  act  or  the
  fulfillment   of   some   condition.   These   are   bonds   secured  by  (a)
  earnings   of   projects   under   construction,  (b)  earnings  of  projects
  unseasoned   in   operating   experience,   (c)   rentals  which  begin  when
  facilities   are   completed,   or   (d)   payments   to   which  some  other
  limiting   condition   attaches.  A  parenthetical  rating  denotes  probable
  credit   stature   upon   completion   of   construction  or  elimination  of
  basis of such condition.
       The   following   summarizes   the   applicable   designations  used  by
  Moody's for short term notes and short term loans:
       MIG1--Loans   bearing   this   designation  are  of  the  best  quality,
  enjoying   strong  protection  from  established  cash  flows  of  funds  for
  their   servicing   or   from  established  and  broad-based  access  to  the
  market for refinancing, or both.
       MIG2--Loans   bearing   this  designation  are  of  high  quality,  with
  margins   of  protection  ample  although  not  so  large  as  the  preceding
  group.

  Ladies and Gentlemen:
  We have served as counsel for PaineWebber Incorporated as
  sponsor and depositor (the "Depositor") of The Municipal Bond
  Trust, Series 230 (hereinafter referred to as the "Trust"). The
  Depositor seeks by means of Post-Effective Amendment No. 3 to
  register for reoffering 2,018 Units acquired by the Depositor in the
  secondary market (hereinafter referred to as the "Units").
  In this regard, we have examined executed originals or copies of the
  following:
  (a)  The Restated Certificate of Incorporation, as amended, and the
       By-Laws of the Depositor, as amended;
  (b)  Resolutions of the Board of Directors of the Depositor adopted on
       December 3, 1971 relating to the Trust and the sale of the Units;
  (c)  Resolutions of the Executive Committee of the Depositor adopted
       on September 24, 1984;
  (d)  Powers of Attorney referred to in the Amendment;
  (e)  Post-Effective Amendment No. 3 to the Registration Statement on
       Form S-6 (File No. 33-38088) to be filed with the Securities and
       Exchange Commission (the "Commission") in accordance with
       the Securities Act of 1933, as amended, and the rules and
       regulations of the Commission promulgated thereunder
       (collectively, the "1933 Act") proposed to be filed on or about the
       date hereof (the "Amendment");
  (f)  The Notification of Registration of the Trust filed with the
       Commission under the Investment Company Act of 1940, as
       amended (collectively, the "1940 Act") on Form N-8A, as
       amended;
  (g)  The registration of the Trust filed with the Commission under the
       1940 Act on Form N-8B-2 (File No. 811-2599), as amended;
  (h)  The prospectus included in the Amendment (the "Prospectus");
  (i)  The Standard Terms and Conditions of the Trust dated as of
       August 1, 1990, as amended, among the Depositor, Investors
       Bank & Trust Company and the First National Bank of Chicago
       (the "Co-Trustees"), as successor C0-Trustees, and Standard &
       Poor's Corporation and Kenny S&P Evaluation Services, a division
       of Kenny Information Systems, Inc. (the "Evaluator") (the
       "Standard Terms");
  (j)  The Trust Indenture dated as of the Date of Deposit, among the
       Depositor, the Co-Trustees and the Evaluator (the "Trust
       Indenture" and, collectively with the Standard Terms, the
       "Indenture and Agreement");
  (k)  The form of certificate of ownership for units (the "Certificate") to
       be issued under the Indenture and Agreement; and
  (l)  Such other pertinent records and documents as we have deemed
       necessary.
       With your permission, in such examination, we have assumed
  the following: (a) the authenticity of original documents and the
  genuineness of all signatures; (b) the conformity to the originals of
  all documents submitted to us as copies; (c) the truth, accuracy,
  and completeness of the information, representations, and warranties
  contained in the records, documents, instruments and certificates we
  have reviewed; (d) except as specifically covered in the opinions set
  forth below, the due authorization, execution, and delivery on behalf
  of the respective parties thereto of documents referred to herein and
  the legal, valid, and binding effect thereof on such parties; and (e)
  the absence of any evidence extrinsic to the provisions of the written
  agreement(s) between the parties that the parties intended a
  meaning contrary to that expressed by those provisions. However,
 <PAGE>
  we have not examined the securities deposited pursuant to the
  Indenture and Agreement (the "Securities") nor the contracts for the
  Securities.
       We express no opinion as to matters of law in jurisdictions other
  than the States of New York and California and the United States,
  except to the extent necessary to render the opinion as to the
  Depositor in paragraph (i) below with respect to Delaware law. As
  you know we are not licensed to practice law in the State of
  Delaware, and our opinion in paragraph (i) and (iii) as to Delaware
  law is based solely on review of the official statutes of the State of
  Delaware.
       Based upon such examination, and having regard for legal
  considerations which we deem relevant, we are of the opinion that:
  (i)  The Depositor is a corporation duly organized, validly existing, and
       in good standing under the laws of the State of Delaware with full
       corporate power to conduct its business as described in the
       Prospectus;
  (ii) The Depositor is duly qualified as a foreign corporation and is in
       good standing as such within the State of New York;
  (iii)The terms and provisions of the Units conform in all material
       respects to the description thereof contained in the Prospectus;
  (iv) The consummation of the transactions contemplated under the
       Indenture and Agreement and the fulfillment of the terms thereof
       will not be in violation of the Depositor's Restated Certificate of
       Incorporation, as amended, or By-Laws, as amended and will not
       conflict with any applicable laws or regulations applicable to the
       Depositor in effect on the date hereof; and
  (v)  The Certificates to be issued by the Trust, when duly executed by
       the Depositor and the Trustee in accordance with the Indenture
       and Agreement, upon delivery against payment therefor as
       described in the Prospectus will constitute fractional undivided
       interests in the Trust enforceable against the Trust in accordance
       with their terms, will be entitled to the benefits of the Indenture
       and Agreement and will be fully paid and non-assessable.
  Our opinion that any document is valid, binding, or enforceable in
  accordance with its terms is qualified as to:
  (a)  limitations imposed by bankruptcy, insolvency, reorganization,
       arrangement, fraudulent conveyance, moratorium, or other laws
       relating to or affecting the enforcement of creditors' rights
       generally;
  (b)  rights to indemnification and contribution which may be limited by
       applicable law or equitable principles; and
  (c)  general principles of equity, regardless of whether such
       enforceability is considered in a proceeding in equity or at law.
       We hereby represent that the Amendment contains no disclosure
  which would render it ineligible to become effective immediately
  upon filing pursuant to paragraph (b) of Rule 485 of the
  Commission.
       We hereby consent to the filing of this opinion as an exhibit to
  the Amendment and to the use of our name wherever it appears in
  the Amendment and the Prospectus.
  Very truly yours,
  /s/ ORRICK, HERRINGTON & SUTCLIFFE
