                            THE MUNICIPAL BOND TRUST
                                INSURED SERIES 41
  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   6,866
  excludable,   in   the   opinion   of   counsel,  from  gross  income    UNIS
  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,    IN-
       SURED   SERIES   41   -The   Municipal   Bond   Trust,   Insured  Series
       41   (the   "Trust")   is   a  unit  investment  trust  formed  for  the
       purpose   of   gaining   Federally   tax-exempt   interest  income  con-
       sistent   with  the  preservation  of  capital  and  diversification  of
       risk   through   investment  in  a  fixed  insured  portfolio  comprised
       of   insured   interest-bearing   municipal  bonds  (the  "Bonds").  (At
       times,  the  Bonds  deposited  in  the  portfolio  are  referred  to  in
       this   Prospectus   as   the  "Securities").  The  payment  of  interest
       and   the  preservation  of  capital  is  dependent  upon  the  continu-
       ing  ability  of  the  bond  insurers  or  the respective issuers of the
       Bonds    to   meet   their   obligations.   Since   PaineWebber   Incor-
       porated   (the   "Sponsor")   and   The   Chase   Manhattan  Bank,  N.A.
       (the   "Trustee")   do   not  have  control  over  the  source  of  pay-
       ment   of   the   Bonds  or  insurance  policy,  they  cannot  guarantee
       that  the  objectives  of  the  Trust  will  be  achieved.  Each unit at
       the   date  hereof  represents  1/6,866th  fractional  undivided  inter-
       est   in   the   $6,725,000   principal   amount   of   bonds   and  net
       income  of  the  Trust  in  the  ratio  of  1  Unit for each $979.46 par
       value  of  Bonds  in  the  Trust.  (See  "Nature  of  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  June  1,  1995,
       $7,203,095.
       INSURANCE--Insurance    guaranteeing    the    payment    of   principal
       and  interest,  at  their  stated  payment  dates,  on  all of the Bonds
       in   the   Trust   has   been  obtained  from  the  Bond  insurers  (the
 <PAGE>
       "Insurers")   indicated   under   "Essential  Information"  in  Part  A.
       The   insurance   policies   are   noncancellable  and  will  remain  in
       force   as   long   as   the   Bonds   insured  by  such  policy  remain
       outstanding.   Because   of   this   Insurance   the   Bonds  and  Units
       are   rated   AAA   by   Standard   &  Poor's  Corporation.  (See  "Sum-
       mary of Portfolio").
       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  (up  to
       5.50%   of  the  Public  Offering  Price).  Units  are  offered  at  the
       Public  Offering  Price  plus  accrued  interest.  (See  "Public  Offer-
       ing   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"   and   "Redemption   of   Units  by  Trustee"  in
       Part B).
       DISTRIBUTIONS--Distributions   of   interest   received  by  the  Trust,
       less   expenses,   will   be   made   on  a  monthly  basis  unless  the
       Certificateholder   elects   to   receive   interest  on  a  semi-annual
       basis.   Distribution   of   principal,  if  any,  will  be  made  on  a
       semi-annual   or   more   frequent   basis.   See   "Essential  Informa-
       tion"  in  Part  A  and  "Distributions  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).

  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.  Each  of  the
  Securities   has   been   insured  against  loss  of  principal  and  against
  non-payment   of   interest   by   bond   insurers.   The   Trust   portfolio
  contains  10  issues  of  interest-bearing  Bonds  issued  by  or  on  behalf
  of  states,  counties  and  municipalities  within  the  United  States,  and
  authorities,   agencies   and   other   such   political   subdivisions.  The
  issuers  of  the  Bonds  in  the  Trust  are  located  in  six states and the
  District   of   Columbia.   Three   issues   of  the  Trust  were  issued  by
  issuers  located  in  the  state  of  Texas,  in  an  approximate  amount  of
  27%   of  the  aggregate  market  value  of  the  Trusts  portfolio,  tending
  to lessen the Trust's geographic diversification of risk.
       On   June  1,  1995,  the  aggregate  market  value  of  the  Securities
  in the Trust, based on the bid side of the market, was $7,203,095.
       All  ten  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:
  5   Refunded   Bonds;   2   Health   and   Hospital  facilities;  1  Resource
  Recovery  facility;  1  Toll  Road;  and  1  University.  The  Trust  may  be
  considered "concentrated" in the following categories of Bonds:
                                                           Percentage of
                                                             Aggregate
  Category of Bond                                          Market Value
  Refunded                                                      29%

       See   "Summary   of  Portfolio"  contained  in  Part  B  for  a  summary
  of   the  Investment  risks  associated  with  the  Securities  contained  in
  the Trust.
  Insurance
       Insurance  guaranteeing  the  payment  of  principal  and  interest,  at
  their  stated  payment  dates,  on  all  the  Bonds  in  the  Trust  has been
  obtained    from   the   bond   insurers   indicated   below   and   on   the
  Schedule   of   Investments,  and  has  been  paid  for  by  the  issuers  of
  the  Bonds  in  the  Trust  or,  in  certain  cases,  by  third parties other
  than   the  issuers.  Insurance  to  Maturity  is  non-cancellable  and  will
  remain   in   force  as  long  as  the  Bonds  so  insured  remain  outstand-
  ing.   Insurance  to  Maturity  does  not  protect  against  changes  in  the
  market value of Units due to changes in prevailing interest rates.

  Ratings
       Standard   &   Poor's   Corporation   rated   each   of  the  Units  and
  Securities   of   the   Trust   "AAA"   because   the  insurers  have  issued
  Insurance   policies   to  insure  each  of  the  Bonds.  The  assignment  of
  such   "AAA"  rating  is  due  solely  to  Standard  &  Poor's  assesment  of
  the  creditworthiness  of  the  insurers  and  their  ability  to  pay claims
  on   their   policies   of  insurance.  This  "AAA"  rating  is  the  highest
  rating   assigned   by   Standard   &  Poor's.  (See  "Bond  Ratings",  here-
  in).   The   rating   should   not   be  construed  as  an  approval  of  the
  offering   of   the   Units   by  Standard  &  Poor's  Corporation  or  as  a
  guarantee  of  the  market  value  of  the  Trust  or  of the Units. Standard
  &   Poor's   has  been  compensated  by  the  Sponsor  for  its  services  in
  rating Units of the Trust.
     
  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  or  will  be  rendered by bond
  counsel   to   the   respective  issuers.  Except  in  certain  instances  in
  which   Orrick,   Herrington   &   Sutcliffe   acted   as   bond  counsel  to
  issuers  of  Securities,  neither  the  Sponsor,  the  Trustee,  nor  counsel
  to   either   has  made  any  review  of  the  proceedings  relating  to  the
  issuance   of  the  Securities  or  the  basis  for  such  opinions.  In  the
  case  of  certain  Securities  in  the  Trust,  the  opinions of bond counsel
  indicate  that  interest  on  such  obligations  received  by  a "substantial
  user"   of   the   facilities  being  financed  with  the  proceeds  of  such
  obligations,   or   "related   person,"  for  periods  such  obligations  are
  held   by   such   "substantial  user"  or  "related  person,"  will  not  be
  exempt  from  federal  income  tax.  Interest  income  attributable  to  such
  Securities   received  by  a  Unitholder  who  is  a  "substantial  user"  or
  "related person" may be taxable to such Unitholder.
       In  the  opinion  of  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
                                        2
 <PAGE>
  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.
       4.   Any   proceeds   representing   maturing   interest   on  defaulted
  obligations  derived  by  Certificateholders  from  insurance  policies  will
  be   excluded   from  gross  income  for  federal  income  tax  purposes  if,
  and   to   the   same   extent   as,   such   interest  would  have  been  so
  excluded if paid by the issuer of such defaulted obligations.
  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
  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
                                        3

  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
  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  separate  returns.  Under  Code  Section
  86,   interest  on  tax-exempt  bonds  is  to  be  added  to  adjusted  gross
  income   for   purposes   of   determining  whether  an  individual's  income
  exceeds   the   base   amount   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
                                        4
 <PAGE>
  individual   alternative   minimum   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  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-
  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-
                                        5

  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
  $10,000   (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
  corporation   pays   no   alternative   minimum  tax.  For  purposes  of  the
  Superfund   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 corporations.
       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
  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
  before   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.
  Plan of Distribution
       Certificateholders  may  elect  to  receive  interest distributions on a
  monthly   or   semi-annual   basis   and   may  make  such  election  at  the
  time  of  purchase  during  the  initial  public offering period and prior to
  the   initial  Record  Date.  The  plan  of  distribution  selected  by  such
  Certificateholders   will   remain   in  effect  until  changed  as  provided
  below.   Those   not   indicating   a   choice   will   be   deemed  to  have
  chosen   the   monthly   distribution   plan.   See  "Essential  Information"
  for   information   concerning  interest  distributions  under  the  optional
  payment   plans.   The   amounts   of   such   distributions  may  change  as
  Securities  mature,  are  called  for  redemption,  or  are  sold  or  if the
  expenses   of  the  Trust  change.  Certificateholders  purchasing  Units  in
  the   secondary   market   will  receive  interest  distributions  in  accor-
  dance  with  the  election  of  the  prior  owner.  In  July  and  January of
  each   year  the  Trustee  will  furnish  all  registered  Certificateholders
  with  a  card  to  be  returned  to  the Trustee not later than the following
  September   1  and  March  1  respectively.  Certificateholders  desiring  to
  change  the  plan  of  distribution  in  which  they  are  participating  may
  so  indicate  on  the  card  and  return  it,  with their Certificate, to the
  Trustee.  If  the  card  and  Certificate  are  returned  to the Trustee, the
  change   in   the   interest  distribution  plan  will  become  effective  on
  September  2  and  March  2  for  the  following  6  months.  If  the card is
  not  returned  to  the  Trustee,  the  Certificateholder  will  be  deemed to
  have   elected   to   continue  with  the  same  plan  for  the  following  6
  months.
  Trustee
       The   Trustee   is   The  Chase  Manhattan  Bank,  N.A., (formerly
  United States Trust Company of New York)  770  Broadway,
  New   York,   New   York   10003.   The  Trustee  is  a  member  of  the  New
  York   Clearing   House   Association  and  is  subject  to  supervision  and
  examination   by   the   Superintendent   of   Banks  of  the  State  of  New
  York,   the   Federal   Deposit   Insurance  Corporation  and  the  Board  of
  Governors of the Federal Reserve System.

   THE CERTIFICATEHOLDERS, SPONSOR AND TRUSTEE
   THE MUNICIPAL BOND TRUST, INSURED SERIES 41:
       We  have  audited  the  accompanying  statement  of  financial  condition,  including  the  schedule of investments, of
   The  Municipal  Bond  Trust,  Insured  Series  41  as  of  June  1,  1995  and  the  related  statements  of  operations and
   changes  in  net  assets  for  each  of  the  three  years  in  the  period  then  ended. These financial statements are the
   responsibility  of  the  Trustee.  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 June 1,
   1995  as  shown  in  the  statement  of  financial  condition  and  schedule  of  investments  by  correspondence  with  the
   Trustee.  An  audit  also  includes  assessing  the  accounting  principles  used  and  significant  estimates  made  by the
   Trustee,  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,  Insured  Series  41  at  June  1,  1995  and  the  results of its operations and
   changes  in  its  net  assets  for  each  of the three years in the period then ended, in conformity with generally accepted
   accounting principles.
                                                                                               ERNST & YOUNG LLP

                               NATURE OF THE TRUST
       Each   series  of  The  Municipal  Bond  Trust,  Insured  Series,  is  a
  unit   investment  trust  formed  for  the  purpose  of  obtaining  federally
  tax-exempt   interest   consistent  with  the  preservation  of  capital  and
  diversification  of  risk  through  investment  in  a  fixed  portfolio  com-
  prised   of   "investment   grade"  (as  of  the  Date  of  Deposit)  insured
  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,  or  any  insurance  proceeds  due  thereon;
  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  their  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, a Division of J.J. Kenny Co., 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
  Bonds  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   entire   ownership   of  the  Trust.  On  the  date  of  Deposit
  each  Unit  represented  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 appropriate Trust.
                              SUMMARY OF PORTFOLIO
 <PAGE>
       An   investment   in   Units  of  the  Trust  should  be  made  with  an
  understanding   of  the  risks  which  an  investment  in  fixed  rate  long-
  term  debt  obligations  may  entail,  including  the  risk that the value of
  the  Trust  portfolio  and  hence  of  the  Units will decline with increases
  in  interest  rates.  The  recent  period  of  high  inflation, together with
  the   fiscal   measures  adopted  to  attempt  to  deal  with  it,  has  seen
  wide  fluctuations  in  interest  rates  and  thus in the value of fixed rate
  long-term   debt   obligations   generally.   The   Sponsor   cannot  predict
  whether such fluctuations will continue in the future.
       As   set   forth   under   "Essential   Information"  and  "Schedule  of
  Investments"  in  Part  A,  the  Trust  may  contain  or  be  concentrated in
  one  or  more  of  the  categories  of  Securities  referred  to  below.  The
  types   of   issuers   and   percentages   of  any  concentrations  for  this
  Trust  are  set  forth  in  Part  A.  These  categories are described in Part
  B  because  an  investment  in  Units  of  the  Trust  should  be  made  with
  an   understanding   of   the  risks  which  these  investments  may  entail.
  Part B also contains a description of the features of this Trust.
  The Portfolio
       Insurance   guaranteeing   the   payment   of  principal  and  interest,
  on   their   stated   payment  dates,  in  respect  of  the  Bonds  has  been
  obtained  either  by  the  issuer  at  the  time  of  issuance  of  the Bonds
  from   one   of   the   independent  insurance  companies  described  herein,
  by  third-party  purchasers  of  the  Securities  or  by  the  Sponsor on the
  Date  of  Deposit  from  the  insurers  identified  in Part A in an effort to
  protect   Unitholders   against   loss   of   principal   and   against  non-
  payment   of   interest.  The  insurance  policies  are  non-cancellable  and
  certain   policies   (as  more  fully  disclosed  under  "Essential  Informa-
  tion"   in  Part  A)  will  continue  in  force  so  long  as  the  Bonds  so
  insured   are   outstanding  (regardless  of  whether  the  Bonds  remain  in
  the   Trust)   (hereinafter   "Insurance  to  Maturity").  The  remainder  of
  the   insurance  policies  will  continue  in  force  only  so  long  as  the
  Bonds   so   insured   are   held   in   the  Trust  (hereinafter  "Portfolio
  Insurance").   The   premium   for   the   Insurance  to  Maturity  has  been
  paid   either  by  the  issuer  at  the  time  of  issuance,  by  third-party
  purchasers  of  the  Securities  or  by  the  Sponsor  and  therefore  is not
  an   expense   of   the   Trust.   Portfolio   Insurance   premiums   are  an
  expense of the Trust.
       *References    are   hereby   made   to   said   Trust   Indenture   and
  Agreement   and   any   statements   contained   herein   are   qualified  in
  their entirety by provisions of said Trust Indenture and Agreement.
 <PAGE>
       There  is  no  assurance  that  the  objectives  of  the  Trust  will be
  met  because  they  are  subject  to  the  continuing  ability of the issuers
  of  the  Securities  held  in  the  Trust  (the "Issuers" or the "Issuer") to
  meet   their   principal  and  interest  payments  and  of  the  insurers  to
  meet   their  obligations  under  the  insurance  policies.  (See  "Essential
  Information   Regarding   the   Trust-Insurance".)   On   the   Date  of  De-
  posit,  an  insurance  policy  or  policies  were  obtained  by  the  Sponsor
  in  respect  of  certain  of  the  Securities  listed  in  the  "Schedule  of
  Investments"   herein.   That   policy   takes   effect   for  each  Security
  which   it   covers   as  and  when  it  is  delivered  to  the  Trustee  for
  deposit in the 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.   The   local   economy  may  be  or  become  concentrated  (i)  in  a
  single  industry,  which  may  be  affected  by  natural  or  other disasters
  or   by   fluctuations   in   commodity  prices,  or  (ii)  in  a  particular
  company,   the   operations   of   which   may   be  impaired  due  to  labor
  disputes,   relocation,   bankruptcy   or   corporate  take-over.  Such  eco-
  nomic  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 legisla-
  ture   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
  governing   the   Security   to   redeem   all  or  a  portion  of  such  ob-
  ligations  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
  mortgagors.   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  unex-
  pended   proceeds   or   prepayments.   The  Sponsor  is  unable  to  predict
  whether   such   redemptions  will  occur,  or  what  effect,  if  any,  such
  redemptions would have on any such Securities in the Trust.
  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
  Techenical   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
  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   attendent   to  lending  to  mortgagors,
  most   of   whom   are   first   time   home   buyers   of  low  or  moderate
  means.
 <PAGE>
       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   bonds   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   requirments   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
 <PAGE>
  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 retrofiling certain
  existing   aircraft   to   comply   with   operating   noise  standards.  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   from  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;  and  changes  in  federal,  state  and
  private   insurance   reimbursement  regulations  and  health  care  delivery
  programs.   The   extent   of   the   AIDS   epidemic  is  undetermined,  and
  the  Sponsor  cannot  predict  its  full  impact  on  the  health care system
  or  particular  issuers.  Utilization  rates for a particular facility may be
  determined    by    cost    containment   programs   implemented   by   third
  party   governmental   providers   or   private   insurers;   long-term   ad-
  vances   in   health   care   delivery   reducing   demand   for   in-patient
  services;   technological   developments   which   may   be  effectively  ra-
  tioned   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 require-
  ments   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  reason-
  able   costs   of   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  re-
  imbursement   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  sys-
 <PAGE>
  tems   for   their   Medicaid  programs,  and  have  adopted  other  changes,
  including   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   lossess   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
  effective  in  1991  (but  not  accounting  for  any  recession)  the  Fund's
  trustees  have  forecast  that  expenditures  will  exceed  tax  revenues  by
  1995   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  provi-
  sions  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   generating   facilities,   which   generally  include  revenues  from
  the   sale  of  electricity  generated  and  distributed  by  power  agencies
  using   hydroelectric,   nuclear,   fossil   fuel  or  other  power  sources.
  Certain  aspects  of  the  operation  of  such  facilities, particularly with
  regard   to   generation   and  transmission  at  the  wholesale  level,  are
  regulated   by   the   Federal   Energy   Regulartory   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  statutes  and  regulations; the difficulties
  of  the  utilities  in  financing  or  refinancing  large  construction  pro-
  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-
 <PAGE>
  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  contractural  basis  with  nuclear  generat-
  ing   facilities,   which   are   licensed   and  regulated  by  the  Nuclear
  Regulatory    Commission    (the   "NRC").   Issuers   of   such   securities
  may   incur   substantial   expenditures   as  a  result  of  complying  with
  NRC   requirements.   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   emergency   evacuation  plans  for  areas  surrounding  nuclear  facili-
  ties;  and  other  issues  associated  with  construction,  licensing,  regu-
  lation,   operation   and   eventual   decommissioning  of  such  facilities.
  These   Securities   may   be   subject   to  industry-wide  fluctuations  in
  market   value   as   a   consequence   of   market   perception  of  certain
  highly   publicized   events,  as  in  the  Washington  Public  Power  Supply
  System's   defaults   on   its   Project  4  and  5  revenue  bonds  and  the
  1988   bankruptcy   filing   by   the   Public  Service  Corporation  of  New
  Hampshire.   Federal,   state   or  municipal  governmental  authorities,  or
  voters   by   initiative,   may   from   time   to   time  impose  additional
  regulations   or   take   such   other   governmental   action   which  might
  cause   delays  in  the  licensing,  construction  or  operation  of  nuclear
  power   plants,   or   the   suspension   or   cessation   of  operations  of
  facilities   which   have   been   or  are  being  financed  by  proceeds  of
  certain Securities in the Trust.
  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
 <PAGE>
  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  facilites,  convention  centers  or  sports  arenas.
  In  the  first  instance,  the  pledged  revenues  may  be  subject to annual
  appropriation  by  a  legislative  body.  In  the latter case, the collection
  of   revenues   may   be   dependent  upon  the  reliability  of  feasibility
  forecasts and assumptions concerning utilization rates.
  Resource Recovery/Solid Waste Securities
       These   Securities  are  typically  secured  by  revenues  derived  from
  the   sale  of  electricity  or  steam  generated  as  a  by-product  of  the
  process   of   incinerating   solid   waste,  and  from  contractual  tipping
  fees,   user  charges  and  ancillary  recycling  earnings.  Special  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
  facilites   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
  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.
 <PAGE>
  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   or  the  guaranty  agencies  guaranteeing  such  loans
  to   properly  service  and  enforce  the  loans  may  cause  the  reimburse-
  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
 <PAGE>
  budgetary   appropration.   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
  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.
 <PAGE>
  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.
                                      ****
  Insurance on the Bonds in the Portfolio
       Certain   of   the   Bonds  in  the  Trust  may  have  been  insured  to
  maturity   by   AMBAC,   MBIA,   MBIAC,   Financial  Guaranty,  BIG,  Capital
  Guaranty,   National   Union   or   USFG  as  to  payment  of  principal  and
  interest  by  the  issuer  at  the  time  of  issuance,  or  by a third party
  purchaser   of   Bonds   subsequest   to  issuance.  For  those  bonds  which
  were   not   so   insured   at   the   time  of  issuance,  the  Sponsor  has
  obtained   an   insurance   policy  or  policies  (except  as  otherwise  set
  forth  in  Part  A).  The  policies  obtained  by  the Sponsor provide either
  for   insurance   as   long  as  the  Bonds  so  insured  remain  outstanding
  ("Insurance   to   Maturity")  or  which  continue  in  force  only  so  long
  as   the   Bonds   so   insured   remain  in  the  Trust  ("Portfolio  Insur-
  ance").   (See   Part   A,   "Essential   Information-Insurance").  Portfolio
  Insurance,   if   any,   has  been  obtained  from  Financial  Guaranty.  Any
  Trust   which   has   obtained   Portfolio   Insurance  has  additionaly  ob-
 <PAGE>
  tained    an    irrevocable   commitment   (the   "Irrevocable   Commitment")
  of   Financial   Guaranty   to  provide  insurance  to  maturity  ("Permanent
  Insurance")   upon   the   sale   of   any  Bond  covered  by  the  Portfolio
  Insurance   from   the   Trust   and   upon   payment   of   a  premium  (the
  "Permanent   Insurance   Premium")   under   certain   conditions  set  forth
  in   Part   A   under   the  heading  "Essential  Information  Regarding  the
  Trust".   The   value  of  the  Bonds  covered  by  the  Portfolio  Insurance
  and,  therefore,  the  Units  may  decline  in  the event of declining credit
  quality.   However,   because   of  the  Irrevocable  Commitment  to  provide
  Permanent   Insurance,   whenever   the  value  of  a  Bond  which  is  below
  investment   grade   and   which   is  covered  by  the  Portfolio  Insurance
  and   insured   to  its  maturity  (less  the  Permanent  Insurance  Premium)
  exceeds  the  value  of  that  Bond  without  such  insurance,  the  value of
  that  Bond  will  be  higher,  insured  to  maturity  value  (See "Evaluation
  of   the  Trust").  The  insurance  policies  are  non-cancellable  and  will
  remain   in   force   as   long   as  the  Bonds  insured  by  such  policies
  remain   outstanding.   Premiums   for   Insurance   to   Maturity  has  been
  paid   either  at  the  time  of  issuance  by  the  Issuer,  by  third-party
  purchasers   or   by   the   Sponsor  on  the  Date  of  Deposit  (see  "Sum-
  mary    of    Portfolio-Insurance    Premiums").   Premiums   for   Portfolio
  Insurance   are   an   expense   of   the   Trust.   (See  "Expenses  of  the
  Trust").   Insurance   does   not   guarantee   the   market   value  of  the
  Bonds   or  the  value  of  the  Units.  Although  the  insurance  represents
  an   element   of   market  value  with  respect  to  the  Bonds  covered  by
  Insurance  to  Maturity,  the  exact  effect,  if  any,  of this insurance on
  the   market   value   cannot   be  predicted.  No  value  is  attributed  to
  Portfolio   Insurance   unless   the   Bond   so   insured   is  rated  below
  investment   grade.   See   "Essential   Information   Regarding  the  Trust-
  Securities  in  the  Trust  Portfolio"  in  Part  A  for  information  on the
  insurance   features  of  this  Trust  and  a  description  of  the  percent-
  ages of the Bonds covered by each of the insurers.
       Payment   under  all  of  these  insurance  policies  will  be  made  in
  respect  of  principal  of  and  interest  on  Bonds  which  shall be due for
  payment   under   the  provisions  of  each  policy,  but  shall  be  unpaid.
  All  such  policies  provide  for  payment  of  the principal or interest due
  to  a  trustee  or  paying  agent  on  the  date  such  payment  is  due.  In
  turn,   such   trustee   or   paying   agent   will   make   payment  to  the
  bondholder  (in  this  case,  the  Trustee)  upon  presentation  of satisfac-
  tory   evidence   of   such  Bondholder's  right  to  receive  such  payment.
  Policies   issued   by   Industrial  Indemnity  Insurance  Company  prior  to
  December   17,  1984  permit  the  Company,  at  its  option,  to  accelerate
  payments under the insurance policies.
       Financial   Guaranty.  Financial  Guaranty,  a  New  York  stock  insur-
  ance   company,   is  located  at  551  Fifth  Avenue,  New  York,  New  York
  10017.    In   determining   whether   to   insure   the   Bonds,   Financial
  Guaranty   has   applied   its   own  standards  which  correspond  generally
  to  the  standards  it  has  established  for determining the insurability of
  new   issues   of   municipal   Bonds  and  which  are  not  necessarily  the
  criteria  used  in  regard  to  the  selection  of  Bonds  by the Sponsor. To
  the  extent  standards  of  Financial  Guaranty  are  more  restrictive  than
  those   of   the   Sponsor,  the  Sponsor's  investment  criteria  have  been
 <PAGE>
  limited to the more restrictive standards.

       Industrial   Indemnity   Insurance   Company.    Certain  of  the  Bonds
  in   the   Portfolio   may   be   insured  under  the  Health  Industry  Bond
  Insurance   ("HIBI")   Program   of   Industrial   Indemnity   Company  ("In-
  dustrial   Indemnity").   Industrial  Indemnity  is  a  wholly-owned  subsid-
  iary   of   Crum   &   Forester,   Inc.,   ("Crum   &   Forester")  which  is
  ultimately    owned   by   Xerox   Corporation.   Effective   September   30,
  1985,   Xerox   Corporation  announced  that  the  operations  of  Industrial
  Indemnity   Corporation   would   be   discontinued,   but   that  Industrial
  Indemnity   Corporation   would   fully   honor   all   insurance  contracts.
  Crum   &   Forester  accrued  $86,400,100,  net  of  an  income  tax  benefit
  of   $73,600,000,   for   expected  operating  losses  during  the  phase-out
  period.  Industrial  Indemnity's  results  of  operations  and  the provision
  for  estimated  losses  during  the  phase-out  period  resulted  in  a  1985
  charge,   after   income  tax  benefits  of  $111,300,000.  At  December  31,
  1985,  Industrial  Indemnity  had  a  $212.2  million  excess  of liabilities
  over   assets.   Crum  &  Forester's  claim-paying  ability  rating  is  "A+"
  and   the  short  term  liquidity  rating  for  commercial  paper  backed  by
  surety   bonds   from   Industrial   Indemnity   Insurance   Company  is  "A-
  1+".   Crum   &   Forester   is   required  by  statute  to  maintain  a  net
  premium/statutory   surplus   ratio   of   3:1.   Xerox  Corporation  contri-
  buted   $366   million   to  Crum  &  Forester  during  the  years  1984  and
  1985   to   maintain  that  ratio.  For  the  fiscal  years  ending  December
  31,   1988   and   1989,  Crum  &  Forester,  Inc.  generated  statutory  net
  income  of  (in  millions)  $340.  and  $364.,  and  statutory  policyholders
  surplus amounted to (in millions) $1,409 and $1,551, respectively.

  Fidelity   and  Guaranty  Company.  These  investors  are  not  obligated  to
  pay   the   debts  or  claims  against  Capital  Guaranty.  As  of  December
  31, 1993   Capital   Guaranty  had  total  admitted  assets  of  $285  million
  and   policyholders   surplus   of   approximately  $168  million  (unaudit-
  ed).   Standard   &   Poor's   Corporation   has   assigned   "AAA"   claims-
  paying   ability   to   Capital   Guaranty.  The  successful  structuring  of
  reinsurance   and   assumption   agreements   in  1987  effectively  replaced
  USF&G   with   Capital   Guaranty  Insurance  Co.  as  the  primary  insurer.

  Ratings
       On   the   Date   of   Deposit   Standard  &  Poor's  Corporation  rated
  each  of  the  Bonds  in  the  Portfolio  and  the  Units  of the Trust "AAA"
  because   the   insurers  have  issued  insurance  policies  to  insure  each
  of  the  Bonds.  The  Units  of  the  Trust  (with  the exception of Units of
  the  Trusts  identified  in  part  A)  continue  to  be rated "AAA". See Part
  A  for  the  current  ratings  on  the  Bonds  and  Units.  (See  also  "Bond
  Ratings",   herein).   The   Bond   and  Unit  ratings  should  not  be  con-
  strued   as  an  approval  of  the  offering  of  the  Units  by  Standard  &
  Poor's   Corporation   or   as  a  guarantee  of  the  market  value  of  the
  Trust   or   of  the  Units.  Standard  &  Poor's  has  been  compensated  by
  the Sponsor for its services in rating Units of the Trust.
  Insurance Premiums
       The  cost  of  the  Insurance  to  Maturity  has  been  paid  either  by
  the  issuers  at  the  time  of  issuance,  by  third-party  purchasers or by
  the Sponsor. Portfolio Insurance premiums are a Trust expense.
                     ACQUISITION OF SECURITIES FOR THE TRUST
       In   selecting  Securities  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.   Insurance   guaranteeing   scheduled   payments  of  principal  and
  interest   and  a  Standard  &  Poor's  Corporation's  rating  of  "AAA"  or,
  in  the  case  of  Securities  not  insured  when  acquired  by  the Sponsor,
  (i)  a  minimum  of  Standard  &  Poor's  Corporation's  rating  of "A", (ii)
  a   minimum  Moody's  Investors  Service,  Inc.'s  rating  of  "A"  or  (iii)
  Bonds    which   the   Sponsor   reasonably   believes   will   obtain   such
 <PAGE>
  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;
       4.  Availability  and  cost  of  insurance  for  the  scheduled  payment
  of   principal   and   interest  on  the  Securities  not  insured  when  ac-
  quired by the Sponsor; and
       5. 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  is  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
  be  initiated  on  a  variety  of  grounds  with respect to Securities in the
  Trust.  Such  litigation  may  affect  the  validity  of  such  Securities or
  the  tax-exempt  status  of  the  interest  thereon.  While  the  outcome  of
  litigation   of   such   nature   cannot   be  predicted,  opinions  of  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
  Securities  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  securities  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 Securities.
                         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.
  In  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
 <PAGE>
  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
  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
 <PAGE>
  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.  Evaluations  for
  purposes    of   secondary   market   transactions   by   the   Sponsor   and
  redemptions   by   the   Trustee  will  be  made  each  business  day  as  of
  the   Evaluation   Time,   effective   for  all  sales  or  redemptions  made
  subsequent to the last preceding determination.
       In   addition   to  the  sales  charge  on  the  Date  of  Deposit,  the
  Sponsor  will  realize  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.   In   addition,  the  Sponsor  may  receive  placement
  fees   or   may   realize   profits   or   sustain  losses  with  respect  to
  Securities   acquired   from  underwriting  syndicates  of  which  the  Spon-
  sor  is  a  member.  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
  sales   charges   will   be   retained   by  the  Sponsor.  The  Sponsor  re-
  serves   the   right  to  reject,  in  whole  or  part,  any  order  for  the
  purchase of Units.
       Initial  Offering  of  Units. During the initial public offering period,
  Units   will  be  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.
                           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
  (see   "Evaluation  of  the  Trust")  by  the  number  of  Units  outstanding
  (see   "Evaluation  of  the  Trust").  There  is  no  sales  charge  incurred
 <PAGE>
  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",  a  price  based
  on  the  current  bid  price  for  the  Securities, plus accrued interest. 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.
       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
 <PAGE>
  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.
 <PAGE>
                  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").  The  es-
  timated   Net   Annual   Interest   Income   per  Unit  will  be  higher  for
  Unitholders   electing   the  semi-annual  interest  distribution  plan  than
  those  electing  the  monthly  plan.  This  is  the  result  of the differing
  expenses   and  fees  of  the  Trustee  in  administering  the  distributions
  of   interest.   See   "Essential  Information"  and  "Distributions  to  Un-
  itholders".
       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  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  (including  all  interest  accrued  and  unpaid  prior  to
  the   Date   of  Deposit  of  the  Securities  and  including  that  part  of
  proceeds  of  the  sale,  liquidation  or  maturity  of  any  Security  which
  represents  accrued  interest  thereon  including  interest  attributable  to
  a   Failed   Security   for   which   no   Replacement   Security   has  been
  obtained   and   including   all   moneys  paid,  if  any,  pursuant  to  the
  Insurance   policy   providing   for   such  payment,  representing  interest
  on  Securities  in  the  Trust)  and  credit  such  interest  to  a  separate
  Interest   Account   created   by  the  Indenture.  All  moneys  received  by
  the  Trustee  from  sources  other  than  interest  will  be  credited  to  a
  separate   Principal  Account.  All  funds  collected  or  received  will  be
  held  by  the  Trustee  in  trust  without  interest  to  Unitholders as part
  of  the  Trust  or  the  Reserve  Account  referred  to  below until required
  to  be  disbursed  in  accordance  with  the  provisions  of  the  Indenture.
  Such   funds  will  be  segregated  by  separate  recordation  on  the  Trust
  ledger   of   the  Trustee  so  long  as  such  practice  preserves  a  valid
  preference   under   applicable   law,   or   if   such   preference  is  not
  preserved,   the   Trustee   shall   handle   such   funds   in   such  other
  manner   as   shall   constitute  the  segregation  and  holding  thereof  in
  trust   within   the   meaning   of  the  Investment  Company  Act  of  1940,
  as   the   same   may   be   from   time  to  time  amended.  To  the  extent
  permitted   by   the  Indenture  and  applicable  banking  regulations,  such
  funds   are   available   for   use   by   the  Trustee  pursuant  to  normal
  banking procedures.
       The  Trustee  is  authorized  by  the  Indenture  to  withdraw  from the
  Principal    and/or    Interest   Accounts   such   amounts   as   it   deems
  necessary   to  establish  a  reserve  for  any  taxes  or  other  governmen-
  tal   charges   that   may  be  payable  out  of  the  Trust,  which  amounts
 <PAGE>
  will   be   deposited   in   a  separate  Reserve  Account.  If  the  Trustee
  determines  that  the  amount  that  is  in  the  Reserve  Account is greater
  than   the   amount   necessary   for   payment   of   any   taxes  or  other
  governmental   charges,   it   will   promptly  deposit  the  excess  in  the
  Account for 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  Trustees  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  or  one-
  half  of  such  Unitholder's  pro  rata  share  (depending  on  the  plan  of
  distribution   selected)   of  the  estimated  annual  amount  to  be  depos-
  ited   in   the  Interest  Account,  computed  as  of  the  preceding  Record
  Date.  However,  all  Unitholders  of  record  on  the  initial  Record  Date
  will  receive  the  initial  interest  distribution  on  the initial Interest
  Distribution  Date.  The  Trustee's  fee  and  expenses  will  be  higher for
  monthly  interest  distributions  than  for  semi-annual  interest  distribu-
  tions.   Therefore,   the   amount   distributed   per  Unit  to  Unitholders
  electing   the   monthly  plan  will  be  correspondingly  lower  than  under
  the  semi-annual  plan.  All  interest  distributions  following  the initial
  interest   distribution   will   be   in   approximately  the  amounts  shown
  under   "Essential  Information",  depending  on  the  plan  of  distribution
  selected.   See  "Essential  Information-Plan  of  Distribution"  in  Part  A
  for details on selecting interest distributions.
       Because   the   Securities   in   the  Trust  pay  interest  at  varying
  semi-annual   intervals  and  Units  pay  interest  at  constant  monthly  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  a  Record  Date.  Pursuant  to  the  Indenture,  in  order to
  accomodate   regular   interest   distributions,   the   Trust  will  contain
  undistributed    cash   balances.   The   difference   between   the   amount
  accrued   to   each   Unitholder   on   a   Record   Date   and   the  amount
  distributed   on   the  following  Distribution  Date  is  an  asset  of  the
  Unitholder   and   will  be  included  as  part  of  accrued  interest  which
  will  be  received  in  subsequent  interest  distributions,  upon  the  sale
  of  his  Units  or,  in  part,  upon  the  sale,  redemption,  or maturity of
  Securities in the Trust.
  Principal Account
       The   Trustee   will   distribute   on   each  semi-annual  Distribution
  Date,  or  shortly  thereafter,  to  Unitholders  of  record on the preceding
  Record   Date,   an   amount  equal  to  such  Unitholder's  pro  rata  share
  of  the  cash  balance,  if  any,  in  the  Principal  Account computed as of
 <PAGE>
  the   proceeding   Record   Date.   Except   for   monies   used   to  redeem
  tendered   Units,   proceeds   received   upon   the   disposition   of   any
  Securities   subsequent   to  a  Record  Date  and  prior  to  the  following
  semi-annual   Distribution  Date  will  be  held  in  the  Principal  Account
  and   will   not   be  distributed  until  the  next  succeeding  semi-annual
  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 distribu-
  tion   will  be  made  within  60  days  of  such  event  to  Unitholders  of
  record   on   the   Record   Date   selected  therefore  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".  The  redemption  price
  for  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   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  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.
  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
 <PAGE>
  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   "Multi-State   Series");  The
  Municipal   Bond   Trust,   California   Series   A   and  subsequent  series
  (the   "California  Series");  The  Corporate  Bond  Trust,  Series  One  and
  subsequent    series   (the   "Corporate   Series");   The   Municipal   Bond
  Trust,   Insured   Series   1   and   subsequent  series  (the  "Insured  Se-
  ries");   and   The   PaineWebber   Pathfinders  Trust  Treasury  and  Growth
  Stock   Series   1   and   subsequent   series  (the  "Pathfinders  Series"),
  The    PaineWebber    Federal   Government   Trust,   GNMA   Series   1   and
  subsequent    series    (the    "Federal    Government    Series")   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   reductions   in   time  and
  expense   related   to   advice,   financial  planning  and  operational  ex-
  pense   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
  exercising  this  option.  Exchange  Trust  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
  and   a   Unitholder  who  purchased  Units  of  a  series  and  paid  a  per
  unit  sales  charge  that  was  less  than  the  per unit sales charge of the
  series   of   Exchange   Trusts   into   which  such  Unitholder  desires  to
  exchange,   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  initial
  sales   charge   paid  in  connection  with  the  acquisition  of  the  Units
  being   exchanged,   equals   the   sales   charge   of  the  series  of  the
 <PAGE>
  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  market  maintained  by  the  Sponsor  in  both  the
  Units  of  this  series  and  units  of  the  applicable  Exchange Trust, and
  there  are  units  of  applicable  Exchange  Trust  available for sale. While
  the  Sponsor  has  indicated  that  it  intends  to  maintain  a  market  for
  the  units  of  the  respective  Trusts,  there  is no obligation on its part
  to  maintain  such  a  market.  Therefore,  there  is  no  assurance  that  a
  market  for  units  will  in  fact  exist  on  any  given  date  at  which  a
  Unitholder  wishes  to  sell  his  Units  of  this  series  and thus there is
  no   assurance   that   the   Exchange   Option   will   be  available  to  a
  Unitholder.   Exchanges   will   be   effected   in  whole  units  only.  Any
  excess   proceeds   from   Unitholders'   units  being  surrendered  will  be
  returned.   Unitholders   will   be   permitted   to  advance  new  money  in
  order to complete an exchange.
       An   exchange   of   units   pursuant   to   the  Exchange  Option  will
  generally   constitute   a   "taxable   event"   under   the  Code,  i.e.,  a
  Unitholder  will  recognize  a  tax  gain  or  loss  at the time of exchange.
  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  associ-
  ations),  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   consequences.   Unitholders  are  advised  to  consult  their  own  tax
  advisors   as   to   the  tax  consequences  of  exchanging  Units  in  their
  particular case.
       The   Sponsor  reserves  the  right  to  modify,  suspend  or  terminate
  this  plan  at  any  time  without  further  notice  to  Unitholders.  In the
  event   the  Exchange  Option  is  not  available  to  a  Unitholder  at  the
  time   he   wishes  to  exercise  it,  the  Unitholder  will  be  immediately
  notified  and  no  action  will  be  taken  with respect to his Units without
  further instruction from the Unitholder.
       To  exercise  the  Exchange  Option,  a  Unitholder  should  notify  the
  Sponsor   of  his  desire  to  exercise  the  Exchange  Opition  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  portofolio  of  the  Trust.  Units  of the Exchange
 <PAGE>
  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
  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
 <PAGE>
       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   incurred   in   establishing   the  Trust,
  including   insurance   premiums   for   the   Insurance   to   Maturity  ob-
  tained  by  the  Sponsor  and  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   cost   of   Portfolio  Insurance  on  the  Bonds  covered  thereby
  while  held  in  the  Trust  is  accounted  for  as  an expense of the Trust.
  Any   amount   paid   for   Permanent   Insurance  on  a  Bond  sold  by  the
  Trust  will  be  accounted  for  as  an  offset  to  the  amount  received on
  the sale.
       For  services  performed  under  the  Indenture,  the  Trustee  will  be
  paid  by  the  Trust  at  the  rate  set  forth under "Essential Information"
  in   Part   A.   Such   compensation   will  be  computed  monthly  or  semi-
  annually   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  evalu-
  ation  is  also  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   Trustee's   fees   are  payable  monthly  and  semi-annually,  and
  the  Evaluator's  fees  are  payable  monthly  on  or  before  each Distribu-
  tion   Date   from   the   Interest   Account,   to   the  extent  funds  are
  available,  then  from  the  Principal  Account.  Any  of  such  fees  may be
  increased   without   approval   of   the   Unitholders   by  an  amount  not
  exceeding   a   proportionate   increase   in   the  category  entitled  "All
  Services   Less   Rent"   in  the  Consumer  Price  Index  published  by  the
  United States Department of Labor.
       In  addition  to  the  above,  the  following  charges  are  or  may  be
  incurred  by  the  Trust  and  paid  from  the  Interest  Account, or, to the
  extent   funds  are  not  available  in  such  Account,  from  the  Principal
  Account:   (1)   fees   for  the  Trustee  for  extraordinary  services;  (2)
  expenses   of  the  Trustee  (including  legal  and  auditing  expenses)  and
  of   counsel;   (3)   various   governmental   charges;   (4)   expenses  and
  costs  of  any  action  taken  by  the  Trustee  to  protect  the  Trust  and
  the  rights  and  interest  of  the  Unitholders;  (5) indemnification of the
  Trustee  for  any  loss,  liabilities  or  expenses  incurred  by  it  in the
  administration  of  the  Trust  without  negligence,  bad  faith  or  willful
  misconduct   on   its   part;   and   (6)  expenses  incurred  in  contacting
  Unitholders   upon   termination   of   the  Trust.  The  fees  and  expenses
  set  forth  above  are  payable  out  of  the  Trust  and  when  unpaid  will
  be secured by a lien on the Trust.
       The   accounts   of   the   Trust   shall   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   Sponsor   maintains   a   secondary  market.  Sponsor  will  bear
  any   audit   expense  which  exceeds  $.50  per  Unit.  Unitholders  covered
 <PAGE>
  by   the   audit   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  his  Certificate  by  presenting  it  to  the  Trustee  at its cor-
  porate   trust   office.  Such  Certificate  must  be  properly  endorsed  or
  accompanied   by   a   written   instrument   or   instruments   of  transfer
  executed   by   the   Unitholder   or   his   duly   authorized  attorney.  A
  Unitholder   may  be  required  to  pay  $2.00  per  Certificate  transferred
  to   cover   the   Trustee's  cost  in  implementing  such  transfer  and  to
  pay   any   tax   or  other  governmental  charge  that  may  be  imposed  in
  connection   with   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  sat-
  isfactory   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

       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

       (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

       (d)   the  deductions  from  the  Principal  Account  for  payment  into

       (e)   the   net   amount   remaining  after  such  payments  and  deduc-

  from  the  Interest  and  Principal  Account,  separately stated,
     expressed  both  as  total  dollar  amounts  and  as  dollar  amounts  per
  Unit   outstanding  on  the  Record  Dates  for  such
  distributions.
                         REDEMPTION OF UNITS BY TRUSTEE
       A  Unitholder  who  wishes  to  dispose  of  its  Units  should  inquire
  through   its   broker  as  to  the  current  market  price  for  such  Units
  prior  to  making  a  tender  for  redemption  to  the  Trustee  in  order to
  determine   if   there   is  a  market  for  Units  in  excess  of  the  then
  current   Redemption   Value   or   Sponsor's  Repurchase  Price.  After  the
  initial  offering  period  the  Redemption  Value  will  be  the  same as the
  Sponsor's Repurchase Price.
       During   the   period   in  which  the  Sponsor  maintains  a  secondary
  market   for   Units   as   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  in  the  City  of  New York,
  properly    endorsed    or   accompanied   by   a   written   instrument   of
 <PAGE>
  transfer   in   form  satisfactory  to  the  Trustee,  and  executed  by  the
  Unitholder   or   its  authorized  attorney.  A  Unitholder  may  tender  its
  Units   for   redemption   at   any   time  after  the  settlement  date  for
  purchase,  whether  or  not  it  has  received  a definitive Certificate. The
  Redemption  Value  per  Unit  is  calculated  by  dividing  the  current  bid
  prices  for  the  Securities  in  the  Trust  (see "Evaluation of the Trust")
  plus   any   money  in  the  Principal  Account  other  than  money  required
  to   redeem  tendered  Units,  by  the  number  of  Units  outstanding,  plus
  a   proportionate  share  of  accrued  interest  and  undistributed  interest
  income  on  the  Securities  determined  to  the  day  of  tender.  There  is
  no  sales  charge  incurred  when  a  Unitholder  tenders  his  Units  to the
  Trustee   for   redemption.   Subject   to  the  payment  of  any  applicable
  tax   or   governmental   charges,   the   Redemption   Value  of  Units  re-
  deemed   by   the   Trustee   will  be  paid  on  the  seventh  calendar  day
  following   the   day   of   tender.  If  such  day  of  payments  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  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  the  redemption  representing  interest  will
  be  withdrawn  from  the  Interest  Account  to  the  extent  that  funds are
  available   for   such   purpose.   All  other  amounts  paid  on  redemption
  will   be   withdrawn   from   the   Principal   Account.   The   Trustee  is
  empowered  to  sell  Securities  out  of  the  Portfolio  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 Information Systems, a  Division  of
  J.J. Kenny Co., Inc.,   65   Broadway,   New   York,   New
 <PAGE>
  York 10006.
       The   value  of  the  Trust  is  computed  as  of  the  Evaluation  Time
  shown   under   "Essential   Information"   (1)   on   each   June   30   and
  December   31   (or  at  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  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.
       The   Evaluator's  evaluation  of  the  Securities  takes  into  account
  Insurance  to  Maturity  insurance  policies  in  respect  of  those  Securi-
  ties  and  the  rating  assigned  to  those  Securities  as  a result of such
  insurance.   Insurance   to   Maturity   determined   the   quality   of  the
  insurance   issued   by  each  insurer,  and  then  compared  the  Securities
  to   other   securities   which  had  comparable  insurance  and  which  were
  of   comparable   quality.  In  addition,  in  the  case  of  Securities  not
  insured   when   acquired   by   the   Sponsor   and  which  are  insured  by
  Portfolio   Insurance,   the   Evaluator  has  attributed  no  value  to  the
  Portfolio   Insurance.   Bonds   rated   below   investment   grade  and  in-
  sured  by  Portfolio  Insurance  will  be  valued  at  the greater of (i) the
  market   value   of  such  Securities  with  Permanent  Insurance  (less  the
  Permanent   Insurance   Premium   therefor)  or  (ii)  the  market  value  of
  such   Securities   uninsured.  In  addition,  the  Evaluator  will  consider
  the  ability  of  Financial  Guaranty  to  meet  its  commitments  under  the
  Portfolio   Insurance,  including  the  ability  to  issue  Permanent  Insur-
  ance.  It  is  the  position  of  the  Sponsor  that this is a fair method of
  valuing   the   Securities   and   reflects  a  proper  valuation  method  in
 <PAGE>
  accordance   with   the   provisions   of   the  Investment  Company  Act  of
  1940.
               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 business
  day  prior  to  the  Date  of  Deposit,  the  Public  Offering Price per Unit
  (which   figure   includes   the   sales   charge)  exceeded  the  Redemption
  Value    by   the   amount   shown   under   "Essential   Information".   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  (except  for  the  limited right to replace
  securities  in  the  case  of  a  fail.  Replacement  Securities  as provided
  herein)   is  prohibited  by  the  Indenture.  The  Sponsor  may  direct  the
  Trustee   to   sell   and  to  liquidate  any  of  the  Securities  upon  the
  happening of any of the following events:
       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  and  such  payment  is  not  guaranteed
  by   a  valid  Insurance  policy  which,  in  the  opinion  of  the  Sponsor,
  will provide adequate payment;
       2.  Institution  of  legal  proceedings  seeking  to  restrain or enjoin
  the payment of any of the Securities or attacking their validity;
       3.   A   breach   of  a  covenant  or  warranty  which  could  adversely
  affect the payment of debt service on the Securities;
       4.   In  the  case  of  revenue  bonds,  if  the  revenues,  based  upon
  official  reports,  fall  substantially  below  the estimated revenues
      calculated  to  be  necessary  to  pay  principal  of and interest on the
  Bonds;
       5.   A  decline  in  market  price,  or  such  other  market  or  credit
  factor,  as  in  the  opinion  of  the  Sponsor  would  make retention of
       any of the Securities detrimental to the Unitholders; or
       6.  In  the  event  that  any  of  the  Bonds  are  the  subject  of  an
  advance refunding.
       It  is  not  anticipated  or  expected  that  disposal  of  any  of  the
  Bonds  in  the  Trust  for  the  reason  described  in  (1)  above will occur
  as  long  as  the  Bonds  are  insured.  The  Trustee  will  not be liable or
 <PAGE>
  responsible   in  any  way  for  depreciation  or  loss  incurred  by  reason
  of  any  sale  made  by  it  either  pursuant  to  a direction of the Sponsor
  or by reason of a failure of the Sponsor to give any such direction.
       The   Sponsor  is  required  to  instruct  the  Trustee  to  reject  any
  offer   made   by   an   Issuer   of   any   of   the   Bonds  to  issue  new
  obligations   in   exchange  and  substitution  for  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  or  records  and  accounts  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 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  execut-
  ing  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  on  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
  that   acceptance   of  the  Trust  by  a  successor  Trustee.  The  Sponsor,
  upon  receiving  notice  of  such  registration,  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-
 <PAGE>
  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
  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  of  the  Trust  unless  the  Trust  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.   Notice   of   such   registration  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  to  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 or responsible in
  any  way  for  depreciation  or  loss  incurred  by  reason  of  the  sale of
  any Securities in the Trust.
       The  Trustee.  The  Indenture  provides  that  the  Trustee  will not be
  liable   for  any  action  taken  in  good  faith  in  reliance  on  properly
  executed   documents   or  for  the  disposition  of  moneys,  Securities  or
  Certificates,  except  by  reason  of  its  own  gross  negligence, bad faith
  or  willful  misconduct,  nor  will  the  Trustee be liable or responsible in
  any  way  for  depreciation  or  loss  incurred  by  reason  of  the  sale by
  the  Trustee  of  any  Securities  in  the Trust. In the event of the failure
 <PAGE>
  of  the  Sponsor  to  act,  the  Trustee  may  act  and will no be liable for
  any  such  action  taken  by  it  in  good  faith.  The  Trustee  will not be
  personally   liable   for   any   taxes   or   other   governmental   charges
  imposed   upon  or  in  respect  to  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  a  present  or future
  law  of  the  United  States  of  America  or  of  any other taxing authority
  having   jurisdiction.   In  addition,  the  Indenture  contains  other  cus-
  tomary  provisions  limiting  the  liability  of  the  Trustee.  The  Trustee
  will  be  indemnified  and  held  harmless  against  any  loss  or  liability
  accruing  to  it  without  negligence,  bad  faith  or  willful misconduct on
  its   part,   arising  out  of  or  in  connection  with  its  acceptance  or
  administration   of   the   Trust,   including   the   costs   and   expenses
  (including   counsel   fees)   of  defending  itself  against  any  claim  of
  liability.
       The   Evaluator.   The   Trustee,   Sponsor  and  Unitholders  may  rely
  on   any   evaluation   furnished   by   the   Evaluator  and  will  have  no
  responsibility   for  the  accuracy  thereof.  The  Indenture  provides  that
  the  determinations  made  by  the  Evaluator  will  be  made  in  good faith
  upon   the   basis   of  the  best  information  available  to  it  provided,
  however,  that  the  Evaluator  will  be  under  no liability to the Trustee,
  Sponsor   or   Unitholders  for  errors  in  judgment,  but  will  be  liable
  only   for  its  gross  negligence,  lack  of  good  faith  or  willful  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  which  may  be
  defective   or  inconsistent  or  to  make  such  other  provisions  as  will
  not  adversely  affect  the  interest  of  the  Unitholders;  provided,  how-
  ever,  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.
                              RIGHT 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  proceeding  in  any  court
  for a partition of winding up of the Trust.
       No  Unitholder  will  have  the  right  to  vote  concerning  the Trust,
 <PAGE>
  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  Certficateholders  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  Termina-
  tion  Date.  Upon  termination,  the  Trustee  will  sell the Securities then
  held  in  the  Trust  and  credit  the  moneys  derived  from  such  sale  to
  the   Principal   Account   and   the  Interest  Account.  The  Trustee  will
  then,   after   deduction   of  any  fees  and  expenses  of  the  Trust  and
  payment   into   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 this
  Certificate  after  due  notice  of  such  termination,  such Unitholders 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
  respect  to  a  specific  debt  obligation.  The  assessment  of creditworth-
  less   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
       II. Nature of and provisions of the obligation
       III.  Protection  afforded  by,  and  relative  position of, the obliga-
  tion   in   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  have  quality  as  high-quality  debt
  obligations.   Capacity  to  pay  principal  and  interest  is  very  strong,
  and  in  the  majority  of  instances  they  differ  from AAA issuers 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.
       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
  within the major rating categories.
       Provisional   Ratings:The   letter  "p"  following  a  rating  indicates
  the  rating  is  provisional.  A  provisional  rating  assumes  the  success-
  ful  completion  of  the  project  being  financed  by  the  issuance  of the
 <PAGE>
  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.
  Moody's Investor 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   risk   appear   somewhat   larger   than   in   Aaa
  securities.
       A   -   Bonds   which   are  rated  A  possess  many  favorable  invest-
  ment   attributes   and   are   to   be  considered  as  upper  medium  grade
  obligations.   Factors   giving   security  to  principal  and  interest  are
  considered   adequate,   but   elements   may  be  present  which  suggest  a
  susceptibility to impairment sometime in the future.
       BAA   -   Bonds   which   are   rated   BAA  are  considered  as  medium
  grade  obligations;  i.e.,  they  are  neither  highly  protected  nor poorly
  secured.   Interest   payments   and   principal   security  appear  adequate
  for   the   present  but  certain  protective  elements  may  be  lacking  or
  may   be  characteristically  unreliable  over  any  great  length  of  time.
  Such   bonds   lack   outstanding  investment  characteristics  and  in  fact
  have speculative characteristics as well.
       Rating   symbols  may  include  numerical  modifiers  1,  2  or  3.  The
  numerical   modifier  1  indicates  that  the  security  ranks  at  the  high
  end,  2  in  the  mid-range,  and  3  nearer  the  low  end  of  the  generic
  category.  These  modifiers  of  rating  symbols,  Aa,  A  and  Baa,  are  to
  give  investors  a  more  precise  indication  of  relative  debt  quality in
  each of the historically defined categories.
       *As described by Standard & Poor's Corporation.
 <PAGE>
       Conditional  ratings,  indicated  by  "Con",  are  given  to  bonds  for
  which   the   security   depends   upon   the   completion  of  some  act  on
  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 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.
  Description of Rating of Units*
       A   Standard   &   Poor's  Corporation's  rating  on  the  units  of  an
  investment  trust  (hereinafter  referred  to  collectively  as  "units"  and
  "fund")   is   current   assessment   of  creditworthiness  with  respect  to
  the   investments   held   by   such   fund.   The   assessment   takes  into
  consideration   the   financial   capacity   of   the   Issuers  and  of  any
  guarantors,   issuers,   lessees,   or   mortgagors   with  respect  to  such
  investments.   The   assessment,   however,   does   not  take  into  account
  the  extent  to  which  fund  expenses  or  Portfolio  asset  sales  for less
  than   the  Fund's  purchase  price  will  reduce  payment  to  the  Unithol-
  der  of  the  interest  and  principal  required  to be paid on the Portfolio
  assets.  In  addition,  the  rating  is  not  a  recommendation  to purchase,
  sell,  or  hold  Units,  inasmuch  as  the  rating  does  not  comment  as to
  market price of the Units or suitability for a particular investor.
       Funds   rated   "AAA"  are  composed  exclusively  of  assets  that  are
  rated   "AAA",   by   Standard   &   Poor's   or  have,  in  the  opinion  of
  Standard   &   Poor's,  credit  characteristics  comparable  to  assets  that
  are   rated   "AAA",   or   certain   short-term   investments.   Standard  &
  Poor's   defines   its   "AAA"   rating   for  such  assets  as  the  highest
  rating  assigned  by  Standard  &  Poor's  to  a  debt  obligation.  Capacity
  to  pay  interest  and  repay  principal  is  very  strong.  Funds  which are
  composed   of   assets   that   are   rated   below   "AAA"   by  Standard  &
  Poor's   Corporation   do   not   carry   a  Standard  &  Poor's  Corporation
  rating on their Units.
       *As described by Standard & Poor's Corporation.

  Ladies and Gentlemen:
  We have served as counsel for PaineWebber Incorporated as
  sponsor and depositor (the "Depositor") of The Municipal Bond

       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

  (i)  The Standard Terms and Conditions of the Trust dated as of

       States Trust Company of New York (the "Trustee"), and Standard
       & Poor's Corporation and Kenny Information Systems, a division
       of J.J. Kenny Co., Inc. (the "Evaluator") (the "Standard Terms");
  (j)  The Trust Indenture dated as of the Date of Deposit, among the
       Depositor, the Trustee and the Evaluator (the "Trust Indenture"
       and, collectively with the Standard Terms, the "Indenture and
       Agreement");
  (k)  The form of certificate of ownership for units (the "Certificate") to
       be issued under the Indenture and Agreement; and
  (l)  Such other pertinent records and documents as we have deemed
       necessary.
       With your permission, in such examination, we have assumed
  the following: (a) the authenticity of original documents and the
  genuineness of all signatures; (b) the conformity to the originals of
  all documents submitted to us as copies; (c) the truth, accuracy,
  and completeness of the information, representations, and warranties
  contained in the records, documents, instruments and certificates we
  have reviewed; (d) except as specifically covered in the opinions set
  forth below, the due authorization, execution, and delivery on behalf
  of the respective parties thereto of documents referred to herein and
  the legal, valid, and binding effect thereof on such parties; and (e)
  the absence of any evidence extrinsic to the provisions of the written
  agreement(s) between the parties that the parties intended a
  meaning contrary to that expressed by those provisions. However,
  we have not examined the securities deposited pursuant to the
 <PAGE>
  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,

  We hereby consent to the use in the Amendment of the reference to

  RE: The Municipal Bond Trust, Insured Series 41
  We have received the post-effective amendment to the registration
  statment SEC file number 33-13803 for the above captioned trust.
  Since the portfolio is composed solely of securities covered by bond
  insurance policies that insure against default in the payment of
  principal and interest on the securities for so long as they remain
  outstanding and such policies have been issued by one or more
  insurance companies which have been assigned 'AAA' claims paying
  ability rating by S&P, we reaffirm the assignment of a 'AAA' rating to
  the units of the trust and a 'AA' rating to the securities contained in
  the trust.
  You have permission to use the name Standard & Poor's
  Corporation and the above-assigned ratings in connection with your
  dissemination of information relating to these units, provided that it
  is understood that the ratings are not "market" ratings nor
  recommendations to buy, hold,or sell the units of the trust or the
  securities in the trust. Further, it should be understood that the
  rating of the units does not take into account the extent to which
  fund expenses or portfiolio asset sales for less than the fund's
  purchase price will reduce payment to the unitholders of the interest
  and principal required to be paid on the portfolio assets. S&P
  reserves the right to advise its own clients, subscribers, and the
  public of the ratings. S&P relies on the sponsor and its counsel,
  accountants, and other experts for the accuracy and completeness
  of the information submitted in connection with the ratings. S&P
  does not independently verify the truth or accuracy of any such
  information.
  This letter evidences our consent to the use of the name of Standard
  & Poor's Corporation in connection with the rating assigned to the
  units in the amendment referred to above. However, this letter
  should not be construed as a consent by us, within the meaning of
  Section 7 of the Securities Act of 1933, to the use of the name of
  Standard and Poor's Corporation in connection with the ratings
  assigned to the securities contained in the trust. You are hereby
  authorized to file a copy of this letter with the Securities and
  Exchange Commission.
  We are pleased to have had the opportunity to be of service to you.
  If we can be of further help, please do not hesitate to call upon us.
