RISK/RETURN SUMMARY


       1.  WHAT IS THE FUND'S OBJECTIVE?
           The Fund seeks high current interest income by investing in
           a fixed portfolio consisting primarily of insured corporate
           bonds.
       2.  WHAT ARE CORPORATE BONDS?
           Corporate bonds are bonds issued by companies, governments
           or other institutions to raise money to use in their
           business or to fund their activities. In return, they pay a
           fixed rate of interest and principal at maturity.
       3.  WHAT IS THE FUND'S INVESTMENT STRATEGY?
           The Fund plans to hold to maturity 8 insured long-term
           corporate bonds, and some short-term U.S. Treasury notes
           reserved to pay the deferred sales fee, with a current
           aggregate face amount of $21,368,000.
           The Fund is a unit investment trust which means that,
           unlike a mutual fund, the Fund's portfolio is not managed.
           The bonds are insured by MBIA while they remain in the
           Portfolio.
           All of the bonds are rated AAA by Standard & Poor's for as
           long as they remain in the Portfolio.
           Many of the bonds can be called at a premium declining over
           time to par value. Some bonds may be called earlier at par
           for extraordinary reasons.
           The Portfolio consists of corporate bonds of the following
           types of issuers:



                                                 APPROXIMATE
                                                  PORTFOLIO
                                                  PERCENTAGE



           Corporate Utilities                            95%
           U.S. Government                               5%



       4.  WHAT ARE THE SIGNIFICANT RISKS?
           YOU CAN LOSE MONEY BY INVESTING IN THE FUND. THIS CAN
           HAPPEN FOR VARIOUS REASONS, INCLUDING:
           Rising interest rates, an issuer's worsening financial
           condition or a drop in bond ratings can reduce the price of
           your units.
           Because the Fund is concentrated in corporate utility
           bonds, adverse developments in these industries may affect
           the value of your units.
           Assuming no changes in interest rates, when you sell your
           units, they will generally be worth less than your cost
           because your cost included a sales fee.
           The Fund will receive early returns of principal if bonds
           are called or sold before they mature. If this happens your
           income will decline and you may not be able to reinvest the
           money you receive at as high a yield or as long a maturity.
       5.  IS THIS FUND APPROPRIATE FOR YOU?
           Yes, if you want current monthly income. You will benefit
           from a professionally selected and supervised portfolio
           whose risk is reduced by investing in insured bonds of
           several different issuers.
           The Fund is not appropriate for you if you want a
           speculative investment that changes to take advantage of
           market movements or if you cannot tolerate any risk.

           DEFINING YOUR INCOME

           WHAT YOU MAY EXPECT (Payable on the 25th day each month):

           These figures are estimates on the evaluation date; actual
           payments may vary.



       6.  WHAT ARE THE FUND'S FEES AND EXPENSES?
           This table shows the costs and expenses you may pay,
           directly or indirectly, when you invest in the Fund.



           INVESTOR FEES
                                                               3.50%
           Maximum Sales Fee (Load) on new purchases

           quarterly November, February, May and August through May,
           2000. Employees of some of the Sponsors and their
           affiliates may be charged a reduced sales fee of no less
           than $5.00 per Unit.
           The maximum sales fee is reduced if you invest at least
           $100,000, as follows:

       7.  HOW HAVE SIMILAR FUNDS PERFORMED IN THE PAST?
           In the following chart we show past performance of prior
           Insured Series of Corporate Income Fund, which had the
           same investment objectives, strategies and types of bonds
           as this Fund. These prior Series differed in that they
           charged a higher sales fee. These prior Insured Series
           were offered between May 5, 1991 and August 7, 1996 and
           were outstanding on March 31, 1999. OF COURSE, PAST
           PERFORMANCE OF PRIOR SERIES IS NO GUARANTEE OF FUTURE
           RESULTS OF THIS FUND.

Note: All returns represent changes in unit price with distributions reinvested

       8.  IS THE FUND MANAGED?
           Unlike a mutual fund, the Fund is not managed and bonds are
           not sold because of market changes. Rather, experienced
           Defined Asset Funds financial analysts regularly review the
           bonds in the Fund. The Fund may sell a bond if certain
           adverse credit or other conditions exist.
       9.  HOW DO I BUY UNITS?
           The minimum investment is one unit.
           You can buy units from any of the Sponsors and other
           broker-dealers. The Sponsors are listed later in this
           prospectus. Some banks may offer units for sale through
           special arrangements with the Sponsors, although certain
           legal restrictions may apply.


                                       4
<PAGE>


           UNIT PRICE PER UNIT                      $1,000.03
           (as of March 31, 1999)
           Unit price is based on the net asset value of the Fund plus
           the up-front sales fee. An amount equal to any principal
           cash, as well as net accrued but undistributed interest on
           the unit, is added to the unit price. An independent
           evaluator prices the bonds at 3:30 p.m. Eastern time every
           business day. Unit price changes every day with changes in
           the prices of the bonds in the Fund.
      10.  HOW DO I SELL UNITS?
           You may sell your units at any time to any Sponsor or the
           Trustee for the net asset value determined at the close of
           business on the date of sale, less any remaining deferred
           sales fee. You will not pay any other fee when you sell your
           units.
      11.  HOW ARE DISTRIBUTIONS MADE AND TAXED?
           The Fund pays income monthly. Interest on the bonds in this
           Fund is subject to federal income taxes for U.S. investors,
           but if you are a non-U.S. investor, your interest may be
           exempt from U.S. federal income taxes, including withholding
           taxes. Interest on the U.S. Treasury notes will be exempt
           from state and local personal income taxes. You will receive
           this interest at the end of each of the years in which they
           mature.



           You will also receive principal payments if bonds are sold
           or called or mature, when the cash available is more than
           $5.00 per unit. You will be subject to tax on any gain
           realized by the Fund on the disposition of bonds.
      12.  WHAT OTHER SERVICES ARE AVAILABLE?
           REINVESTMENT
           You will receive your monthly income in cash unless you
           choose to compound your income by reinvesting at no sales
           fee in the Corporate Fund Investment Accumulation Program,
           Inc. This program is an open-end mutual fund with a
           comparable investment objective, but those bonds are not
           insured. Income from this program will be subject to U.S.
           federal income taxes for both U.S. and foreign investors.
           For more complete information about the program, including
           charges and fees, ask the Trustee for the program's
           prospectus. Read it carefully before you invest. The
           Trustee must receive your written election to reinvest at
           least 10 days before the record day of an income payment.
           EXCHANGE PRIVILEGES
           You may exchange units of this Fund for units of certain
           other Defined Asset Funds. You may also exchange into this
           Fund from certain other funds. We charge a reduced sales
           fee on exchanges.

WHAT YOU CAN EXPECT FROM YOUR INVESTMENT
MONTHLY INCOME

The Fund will pay you regular monthly income. Your monthly income may vary
because of:
   elimination of one or more bonds from the Fund's portfolio because of calls,
    redemptions or sales;
   a change in the Fund's expenses; or
   the failure by a bond's issuer to pay interest.
Changes in interest rates generally will not affect your monthly income because
the portfolio is fixed.
Along with your monthly income, you will receive your share of any available
bond principal.
Return Figures We cannot predict your actual return, which will vary with unit
price, how long you hold your investment and changes in the portfolio, interest
income and expenses.
Estimated Current Return equals the estimated annual cash to be received from
the bonds in the Fund less estimated annual Fund expenses, divided by the Unit
Price (including the maximum sales fee):


 Estimated Annual                  Estimated
 Interest Income                Annual Expenses
- -------------------------------------------------
                   Unit Price


Estimated Long Term Return is a measure of the estimated return over the
estimated life of the Fund. Unlike Estimated Current Return, Estimated Long Term
Return reflects maturities, discounts and premiums of the bonds in the Fund. It
is an average of the yields to maturity (or in certain cases, to an earlier call
date) of the individual bonds in the portfolio, adjusted to reflect the Fund's
maximum sales fee and estimated expenses. We calculate the average yield for the
portfolio by weighting each bond's yield by its market value and the time
remaining to the call or maturity date.
Yields on individual bonds depend on many factors including general conditions
of the bond markets, the size of a particular offering and the maturity and
quality rating of the particular issues. Yields can vary among bonds with
similar maturities, coupons and ratings.
These return quotations are designed to be comparative rather than predictive.
Records and Reports You will receive:
a monthly statement of income payments and any principal payments;
a notice from the Trustee when new bonds are deposited in exchange or
 substitution for bonds originally deposited;
an annual report on Fund activity; and
annual tax information. This will also be sent to the IRS. You must report the
 amount of interest received during the year.
You may request:
copies of bond evaluations to enable you to comply with federal and state tax
 reporting requirements; and
audited financial statements of the Fund.
You may inspect records of Fund transactions at the Trustee's office during
regular business hours.

THE RISKS YOU FACE
INTEREST RATE RISK
INVESTING INVOLVES RISKS, INCLUDING THE RISK THAT YOUR INVESTMENT WILL DECLINE
IN VALUE IF INTEREST RATES RISE. GENERALLY, BONDS WITH LONGER MATURITIES WILL
CHANGE IN VALUE MORE THAN BONDS WITH SHORTER MATURITIES. BONDS IN THE FUND ARE
MORE LIKELY TO BE CALLED WHEN INTEREST RATES DECLINE. THIS WOULD RESULT IN EARLY
RETURNS OF PRINCIPAL TO YOU AND MAY RESULT IN EARLY TERMINATION OF THE FUND. OF
COURSE, WE CANNOT PREDICT HOW INTEREST RATES MAY CHANGE.
CALL RISK MANY BONDS CAN BE PREPAID OR 'CALLED' BY THE ISSUER BEFORE THEIR
STATED MATURITY. FOR EXAMPLE, SOME BONDS MAY BE REQUIRED TO BE CALLED PURSUANT
TO MANDATORY SINKING FUND PROVISIONS.
ALSO, AN ISSUER MIGHT CALL ITS BONDS DURING PERIODS OF FALLING INTEREST RATES,
IF THE ISSUER'S BONDS HAVE A COUPON HIGHER THAN CURRENT MARKET RATES.
IF THE BONDS ARE CALLED, YOUR INCOME WILL DECLINE AND YOU MAY NOT BE ABLE TO
REINVEST THE MONEY YOU RECEIVE AT AS HIGH A YIELD OR AS LONG A MATURITY. AN
EARLY CALL AT PAR OF A PREMIUM BOND WILL REDUCE YOUR RETURN.
REDUCED DIVERSIFICATION RISK IF MANY INVESTORS SELL THEIR UNITS, THE FUND WILL
HAVE TO SELL BONDS. THIS COULD REDUCE THE DIVERSIFICATION OF YOUR INVESTMENT AND
INCREASE YOUR SHARE OF FUND EXPENSES.
LIQUIDITY RISK THE BONDS WILL GENERALLY TRADE IN THE OVER-THE-COUNTER MARKET. WE
CANNOT ASSURE YOU THAT A LIQUID TRADING MARKET WILL EXIST, ESPECIALLY SINCE
CURRENT LAW MAY RESTRICT THE FUND FROM SELLING BONDS TO ANY SPONSOR. THE VALUE
OF THE BONDS, AND OF YOUR INVESTMENT, MAY BE REDUCED IF TRADING IN BONDS IS
LIMITED OR ABSENT.
CONCENTRATION RISK
WHEN A CERTAIN TYPE OF BOND MAKES UP 25% OR MORE OF THE PORTFOLIO, THE FUND IS
SAID TO BE

                                       6
<PAGE>
'CONCENTRATED' IN THAT BOND TYPE, WHICH MAKES THE FUND LESS DIVERSIFIED.
HERE IS WHAT YOU SHOULD KNOW ABOUT THE FUND'S CONCENTRATION IN CORPORATE UTILITY
BONDS, INCLUDING TELECOMMUNICATIONS BONDS:
   PAYMENT FOR THESE BONDS DEPENDS ON RATES THAT THE UTILITY COMPANIES MAY
   CHARGE, THE DEMAND FOR THEIR SERVICES AND THEIR OPERATING COSTS;
   ELECTRIC UTILITIES FACE PRESSURE TO KEEP RATES LOW, WHICH MAY MAKE IT
   DIFFICULT TO RECOVER INVESTMENTS IN GENERATING PLANT;
   UTILITIES GENERALLY ARE SENSITIVE TO COSTS AND AVAILABILITY OF FUEL;
   SOME ELECTRIC UTILITIES ARE SUBJECT TO THE RISKS OF THE NUCLEAR INDUSTRY;
   TELECOMMUNICATIONS COMPANIES ARE EXTENSIVELY REGULATED AND THE INDUSTRY IS
    INCREASINGLY COMPETITIVE; AND
   THE RATE OF TECHNOLOGICAL INNOVATION HAS A MAJOR IMPACT ON TELECOMMUNICATIONS
    COMPANIES.
CHANGES TO THE PORTFOLIO FROM BOND REDEMPTIONS, MATURITIES AND SALES MAY AFFECT
THE FUND'S CONCENTRATION OVER TIME.
BOND QUALITY RISK A REDUCTION IN A BOND'S RATING MAY DECREASE ITS VALUE AND,
INDIRECTLY, THE VALUE OF YOUR INVESTMENT IN THE FUND.
INSURANCE RELATED RISK THE BONDS ARE BACKED BY MBIA INSURANCE CORPORATION AS
LONG AS THEY REMAIN IN THE FUND. INSURANCE POLICIES GENERALLY MAKE PAYMENTS ONLY
ACCORDING TO A BOND'S ORIGINAL PAYMENT SCHEDULE AND DO NOT MAKE EARLY PAYMENTS
WHEN A BOND DEFAULTS OR BECOMES TAXABLE. ALTHOUGH THE FEDERAL GOVERNMENT DOES
NOT REGULATE THE INSURANCE BUSINESS, VARIOUS STATE LAWS AND FEDERAL INITIATIVES
AND TAX LAW CHANGES COULD SIGNIFICANTLY AFFECT THE INSURANCE BUSINESS. THE
CLAIMS-PAYING ABILITY OF MBIA IS RATED AAA BY STANDARD & POOR'S. INSURANCE
COMPANY RATINGS ARE SUBJECT TO CHANGE AT ANY TIME AT THE DISCRETION OF THE
RATING AGENCIES.
LITIGATION RISK WE DO NOT KNOW OF ANY PENDING LITIGATION THAT MIGHT HAVE A
MATERIAL ADVERSE EFFECT UPON THE FUND.

SELLING OR EXCHANGING UNITS
YOU CAN SELL YOUR UNITS AT ANY TIME FOR A PRICE BASED ON NET ASSET VALUE. YOUR
NET ASSET VALUE IS CALCULATED EACH BUSINESS DAY BY:
     adding the value of the bonds, net accrued interest, cash and any other
     Fund assets;
     subtracting accrued but unpaid Fund expenses, unreimbursed Trustee
     advances, cash held to buy back units or for distribution to investors and
      any other Fund liabilities; and
     dividing the result by the number of outstanding units.
      Your net asset value when you sell may be more or less than your cost
     because of sales fees, market movements and changes in the portfolio.
      If you sell your units before the final deferred sales fee installment,
     the amount of any remaining installments will be deducted from your
     proceeds.
      Sponsors' Secondary Market While we are not obligated to do so, we will
     buy back units at net asset value without any other fee or charge other
     than any remaining deferred sales charge. We may resell the units to other
     buyers or to the Trustee. You should consult your financial professional
     for current market prices to determine if other broker-dealers or banks are
     offering higher prices.
      We have maintained a secondary market continuously for over 25 years,

                                       7
<PAGE>
      but we could discontinue it without prior notice for any business reason.
      Selling Units to the Trustee Regardless of whether we maintain a secondary
      market, you can sell your units to the Trustee at any time by sending the
      Trustee a letter (with any outstanding certificates if you hold unit
      certificates). You must properly endorse your certificates (or execute a
      written transfer instrument with signatures guaranteed by an eligible
      institution). Sometimes, additional documents are needed such as a trust
      document, certificate of corporate authority, certificate of death or
      appointment as executor, administrator or guardian.
      Within seven days after your request and the necessary documents are
      received, the Trustee will mail a check to you. Contact the Trustee for
      additional information.
      As long as we are maintaining a secondary market, the Trustee will sell
      your units to us at a price based on net asset value. If there is no
      secondary market, the Trustee may sell your units in the over-the-counter
      market for a higher price, but it is not obligated to do so. In that case,
      you will receive the net proceeds of the sale.
      If the Fund does not have cash available to pay you for units you are
      selling, the agent for the Sponsors will select bonds to be sold. Bonds
      will be selected based on market and credit factors. These sales could be
      made at times when the bonds would not otherwise be sold and may result in
      your receiving less than the unit par value and also reduce the size and
      diversity of the Fund.
      If you acquire 25% or more of the outstanding units of the Fund and you
      sell units with a value exceeding $250,000, the Trustee may choose to pay
      you 'in kind' by distributing bonds and cash with a total value equal to
      the price of those units. The Trustee will try to distribute bonds in the
      portfolio pro rata, but it reserves the right to distribute only one or a
      few bonds. The Trustee will act as your agent in an in kind distribution
      and will either hold the bonds for your account or sell them as you
      instruct. You must pay any transaction costs as well as transfer and
      ongoing custodial fees on sales of bonds distributed in kind.
      There could be a delay in paying you for your units:
     if the New York Stock Exchange is closed (other than customary weekend and
     holiday closings);

                                       8
<PAGE>
     if the SEC determines that trading on the New York Stock Exchange is
     restricted or that an emergency exists making sale or evaluation of the
     bonds not reasonably practicable; and
     for any other period permitted by SEC order.
Exchange Option You may exchange units of certain Defined Asset Funds for units
of this Fund at a maximum exchange fee of 2.50%. You may exchange units of this
Fund for units of certain other funds at a reduced sales fee if your investment
goals change. To exchange units, you should talk to your financial professional
about what funds are exchangeable, suitable and currently available.
Normally, an exchange is taxable and you must recognize any gain or loss on the
exchange. However, the IRS may try to disallow a loss if the portfolios of the
two funds are not materially different; you should consult your own tax adviser.
We may amend or terminate this exchange option at any time without notice.
HOW THE FUND WORKS
PRICING THE PRICE OF A UNIT INCLUDES INTEREST ACCRUED ON THE BONDS, LESS
EXPENSES, FROM THE MOST RECENT RECORD DAY UP TO, BUT NOT INCLUDING, THE
SETTLEMENT DATE, WHICH IS USUALLY THREE BUSINESS DAYS AFTER THE PURCHASE DATE OF
THE UNIT.
A PORTION OF THE PRICE OF A UNIT CONSISTS OF CASH SO THAT THE TRUSTEE CAN
PROVIDE YOU WITH REGULAR MONTHLY INCOME. WHEN YOU SELL YOUR UNITS YOU WILL
RECEIVE YOUR SHARE OF THIS CASH.
IN ADDITION, AS WITH MUTUAL FUNDS, THE FUND (AND THEREFORE THE INVESTORS) PAY
ALL OR SOME OF THE COSTS OF ORGANIZING THE FUND INCLUDING:
     COST OF INITIAL PREPARATION OF LEGAL DOCUMENTS;
     FEDERAL AND STATE REGISTRATION FEES;
     INITIAL FEES AND EXPENSES OF THE TRUSTEE;
     INITIAL AUDIT; AND
     LEGAL EXPENSES AND OTHER OUT-OF-POCKET EXPENSES.
EVALUATIONS AN INDEPENDENT EVALUATOR VALUES THE BONDS ON EACH BUSINESS DAY
(EXCLUDING SATURDAYS, SUNDAYS AND THE FOLLOWING HOLIDAYS AS OBSERVED BY THE NEW
YORK STOCK EXCHANGE: NEW YEAR'S DAY, PRESIDENTS' DAY, MARTIN LUTHER KING, JR.
DAY, GOOD FRIDAY, MEMORIAL DAY, INDEPENDENCE DAY, LABOR DAY, THANKSGIVING AND
CHRISTMAS). BOND VALUES ARE BASED ON CURRENT BID OR OFFER PRICES FOR THE BONDS
OR COMPARABLE BONDS. IN THE PAST, THE DIFFERENCE BETWEEN BID AND OFFER PRICES OF
PUBLICLY OFFERED BONDS HAS RANGED FROM 0.25% OF FACE AMOUNT ON ACTIVELY TRADED
ISSUES TO 1.5% ON INACTIVELY TRADED ISSUES; THE DIFFERENCE HAS AVERAGED BETWEEN
0.5% AND 1%.
INCOME THE TRUSTEE CREDITS INTEREST TO AN INCOME ACCOUNT AND OTHER RECEIPTS TO A
CAPITAL

                                       9
<PAGE>
ACCOUNT. THE TRUSTEE MAY ESTABLISH A RESERVE ACCOUNT BY WITHDRAWING FROM THESE
ACCOUNTS AMOUNTS IT CONSIDERS APPROPRIATE TO PAY ANY MATERIAL LIABILITY. THESE
ACCOUNTS DO NOT BEAR INTEREST.
EXPENSES
THE TRUSTEE IS PAID MONTHLY. IT ALSO BENEFITS WHEN IT HOLDS CASH FOR THE FUND IN
NON-INTEREST BEARING ACCOUNTS. THE TRUSTEE MAY ALSO RECEIVE ADDITIONAL AMOUNTS:
     TO REIMBURSE THE TRUSTEE FOR THE FUND'S OPERATING EXPENSES;
     FOR EXTRAORDINARY SERVICES AND COSTS OF INDEMNIFYING THE TRUSTEE AND THE
     SPONSORS;
     COSTS OF ACTIONS TAKEN TO PROTECT THE FUND AND OTHER LEGAL FEES AND
     EXPENSES;
     EXPENSES FOR KEEPING THE FUND'S REGISTRATION STATEMENT CURRENT; AND
     FUND TERMINATION EXPENSES AND ANY GOVERNMENTAL CHARGES.
      THE SPONSORS ARE CURRENTLY REIMBURSED UP TO 45 PER $1,000 FACE AMOUNT
     ANNUALLY FOR PROVIDING PORTFOLIO SUPERVISORY, BOOKKEEPING AND
      ADMINISTRATIVE SERVICES AND FOR ANY OTHER EXPENSES PROPERLY CHARGEABLE TO
     THE FUND. LEGAL, TYPESETTING, ELECTRONIC FILING AND REGULATORY FILING FEES
     AND EXPENSES ASSOCIATED WITH UPDATING THE PORTFOLIO'S REGISTRATION
     STATEMENT YEARLY ARE ALSO NOW CHARGEABLE TO THE PORTFOLIO. WHILE THIS FEE
     MAY EXCEED THE AMOUNT OF THESE COSTS AND EXPENSES ATTRIBUTABLE TO THIS
     FUND, THE TOTAL OF THESE FEES FOR ALL SERIES OF DEFINED ASSET FUNDS WILL
     NOT EXCEED THE AGGREGATE AMOUNT ATTRIBUTABLE TO ALL OF THESE SERIES FOR ANY
      CALENDAR YEAR. THE FUND ALSO PAYS THE EVALUATOR'S FEES.
      THE TRUSTEE'S, SPONSORS' AND EVALUATOR'S FEES MAY BE ADJUSTED FOR
     INFLATION WITHOUT INVESTORS' APPROVAL.
      ANY QUARTERLY DEFERRED SALES CHARGES YOU OWE ARE PAID WITH INTEREST AND
     PRINCIPAL FROM CERTAIN BONDS. IF THESE AMOUNTS ARE NOT ENOUGH, THE REST
     WILL BE PAID OUT OF DISTRIBUTIONS TO YOU FROM THE FUND'S CAPITAL AND INCOME
     ACCOUNTS.
      THE SPONSORS WILL PAY ADVERTISING AND SELLING EXPENSES AT NO CHARGE TO THE
      FUND. IF FUND EXPENSES EXCEED INITIAL ESTIMATES, THE FUND WILL OWE THE
     EXCESS. THE TRUSTEE HAS A LIEN ON FUND ASSETS TO SECURE REIMBURSEMENT OF
     FUND EXPENSES AND MAY SELL BONDS IF CASH IS NOT AVAILABLE.
      PORTFOLIO CHANGES THE SPONSORS AND TRUSTEE ARE NOT LIABLE FOR ANY DEFAULT
     OR DEFECT IN A BOND.
      UNLIKE A MUTUAL FUND, THE PORTFOLIO IS DESIGNED TO REMAIN INTACT AND WE
     MAY KEEP BONDS IN THE PORTFOLIO EVEN IF THEIR CREDIT QUALITY DECLINES OR
     OTHER ADVERSE FINANCIAL CIRCUMSTANCES OCCUR. HOWEVER, WE MAY SELL A BOND IN
     CERTAIN CASES IF WE BELIEVE THAT CERTAIN

                                       10
<PAGE>
      ADVERSE CREDIT OR CERTAIN OTHER CONDITIONS EXIST.
      IF WE MAINTAIN A SECONDARY MARKET IN UNITS BUT ARE UNABLE TO SELL THE
      UNITS THAT WE BUY IN THE SECONDARY MARKET, WE WILL REDEEM UNITS, WHICH
      WILL AFFECT THE SIZE AND COMPOSITION OF THE PORTFOLIO. UNITS OFFERED IN
      THE SECONDARY MARKET MAY NOT REPRESENT THE SAME FACE AMOUNT OF BONDS THAT
      THEY DID ORIGINALLY.
      WE DECIDE WHETHER OR NOT TO OFFER UNITS FOR SALE THAT WE ACQUIRE IN THE
      SECONDARY MARKET AFTER REVIEWING:
     DIVERSITY OF THE PORTFOLIO;
     SIZE OF THE FUND RELATIVE TO ITS ORIGINAL SIZE;
     RATIO OF FUND EXPENSES TO INCOME;
     CURRENT AND LONG-TERM RETURNS;
     DEGREE TO WHICH UNITS MAY BE SELLING AT A PREMIUM OVER PAR; AND
     COST OF MAINTAINING A CURRENT PROSPECTUS.
FUND TERMINATION THE FUND WILL TERMINATE FOLLOWING THE STATED MATURITY OR SALE
OF THE LAST BOND IN THE PORTFOLIO. THE FUND MAY ALSO TERMINATE EARLIER WITH THE
CONSENT OF INVESTORS HOLDING 51% OF THE UNITS OR IF TOTAL ASSETS OF THE FUND
HAVE FALLEN BELOW 40% OF THE FACE AMOUNT OF BONDS DEPOSITED. WE WILL DECIDE
WHETHER TO TERMINATE THE FUND EARLY BASED ON THE SAME FACTORS USED IN DECIDING
WHETHER OR NOT TO OFFER UNITS IN THE SECONDARY MARKET.
WHEN THE FUND IS ABOUT TO TERMINATE YOU WILL RECEIVE A NOTICE, AND YOU WILL BE
UNABLE TO SELL YOUR UNITS AFTER THAT TIME. ON OR SHORTLY BEFORE TERMINATION, WE
WILL SELL ANY REMAINING BONDS, AND YOU WILL RECEIVE YOUR FINAL DISTRIBUTION. ANY
BOND THAT CANNOT BE SOLD AT A REASONABLE PRICE MAY CONTINUE TO BE HELD BY THE
TRUSTEE IN A LIQUIDATING TRUST PENDING ITS FINAL SALE.
YOU WILL PAY YOUR SHARE OF THE EXPENSES ASSOCIATED WITH TERMINATION, INCLUDING
BROKERAGE COSTS IN SELLING BONDS. THIS MAY REDUCE THE AMOUNT YOU RECEIVE AS YOUR
FINAL DISTRIBUTION.
CERTIFICATES CERTIFICATES FOR UNITS ARE ISSUED ON REQUEST. YOU MAY TRANSFER
CERTIFICATES BY COMPLYING WITH THE REQUIREMENTS FOR REDEEMING CERTIFICATES,
DESCRIBED ABOVE. YOU CAN REPLACE LOST OR MUTILATED CERTIFICATES BY DELIVERING
SATISFACTORY INDEMNITY AND PAYING THE ASSOCIATED COSTS.
TRUST INDENTURE THE FUND IS A 'UNIT INVESTMENT TRUST' GOVERNED BY A TRUST
INDENTURE, A CONTRACT AMONG THE SPONSORS, THE TRUSTEE AND THE EVALUATOR, WHICH
SETS FORTH THEIR DUTIES AND OBLIGATIONS AND YOUR RIGHTS. A COPY OF THE INDENTURE
IS AVAILABLE TO YOU ON REQUEST TO THE TRUSTEE. THE FOLLOWING SUMMARIZES CERTAIN
PROVISIONS OF THE INDENTURE.
THE SPONSORS AND THE TRUSTEE MAY AMEND THE INDENTURE WITHOUT YOUR CONSENT:
     TO CURE AMBIGUITIES;

                                       11
<PAGE>
     TO CORRECT OR SUPPLEMENT ANY DEFECTIVE OR INCONSISTENT PROVISION;
     TO MAKE ANY AMENDMENT REQUIRED BY ANY GOVERNMENTAL AGENCY; OR
     TO MAKE OTHER CHANGES DETERMINED NOT TO BE MATERIALLY ADVERSE TO YOUR BEST
     INTEREST (AS DETERMINED BY THE SPONSORS).
INVESTORS HOLDING 51% OF THE UNITS MAY AMEND THE INDENTURE. EVERY INVESTOR MUST
CONSENT TO ANY AMENDMENT THAT CHANGES THE 51% REQUIREMENT. NO AMENDMENT MAY
REDUCE YOUR INTEREST IN THE FUND WITHOUT YOUR WRITTEN CONSENT.
THE TRUSTEE MAY RESIGN BY NOTIFYING THE SPONSORS. THE SPONSORS MAY REMOVE THE
TRUSTEE WITHOUT YOUR CONSENT IF:
     IT FAILS TO PERFORM ITS DUTIES AND THE SPONSORS DETERMINE THAT ITS
      REPLACEMENT IS IN YOUR BEST INTEREST; OR
     IT BECOMES INCAPABLE OF ACTING OR BANKRUPT OR ITS AFFAIRS ARE TAKEN OVER BY
     PUBLIC AUTHORITIES.
INVESTORS HOLDING 51% OF THE UNITS MAY REMOVE THE TRUSTEE. THE EVALUATOR MAY
RESIGN OR BE REMOVED BY THE SPONSORS AND THE TRUSTEE WITHOUT THE CONSENT OF
INVESTORS. THE RESIGNATION OR REMOVAL OF EITHER BECOMES EFFECTIVE WHEN A
SUCCESSOR ACCEPTS APPOINTMENT. THE SPONSORS WILL TRY TO APPOINT A SUCCESSOR
PROMPTLY; HOWEVER, IF NO SUCCESSOR HAS ACCEPTED WITHIN 30 DAYS AFTER NOTICE OF
RESIGNATION, THE RESIGNING TRUSTEE OR EVALUATOR MAY PETITION A COURT TO APPOINT
A SUCCESSOR.
ANY SPONSOR MAY RESIGN AS LONG AS ONE SPONSOR WITH A NET WORTH OF $2 MILLION
REMAINS AND AGREES TO THE RESIGNATION. THE REMAINING SPONSORS AND THE TRUSTEE
MAY APPOINT A REPLACEMENT. IF THERE IS ONLY ONE SPONSOR AND IT FAILS TO PERFORM
ITS DUTIES OR BECOMES BANKRUPT THE TRUSTEE MAY:
     REMOVE IT AND APPOINT A REPLACEMENT SPONSOR;
     LIQUIDATE THE FUND; OR
     CONTINUE TO ACT AS TRUSTEE WITHOUT A SPONSOR.
MERRILL LYNCH, PIERCE, FENNER & SMITH INCORPORATED ACTS AS AGENT FOR THE

Each Sponsor is a Delaware corporation and it, or its predecessor, has acted as
sponsor to many unit investment trusts. As a registered broker-dealer each
Sponsor buys and sells securities (including investment company shares) for
others (including investment companies) and participates as an underwriter in
various selling groups.
Trustee The Bank of New York,101 Barclay Street--17W, New York, New York 10268,
is the Trustee.
It is supervised by the Federal Deposit Insurance Corporation, the Board of
Governors of the Federal Reserve System and New York State banking authorities.
Underwriters' and Sponsors' Profits Underwriters receive sales charges when they
sell units. The Sponsors also realized a profit or loss on the initial deposit
of the bonds. Any cash made available by you to the Sponsors before the
settlement date for those units may be used in the Sponsors' businesses to the
extent permitted by federal law and may benefit the Sponsors.
A Sponsor or Underwriter may realize profits or sustain losses on bonds in the
Fund which were acquired from underwriting syndicates of which it was a member.
In maintaining a secondary market, the Sponsors will also realize profits or
sustain losses in the amount of any difference between the prices at which they
buy units and the prices at which they resell or redeem them.
Public Distribution The Sponsors do not intend to qualify units for sale in any
foreign countries. This prospectus does not constitute an offer to sell units in
any country where units cannot lawfully be sold.
Code of Ethics Merrill Lynch, as agent for the Sponsors, has adopted a code of
ethics requiring preclearance and reporting of personal securities transactions
by its employees with access to information on portfolio transactions. The goal
of the code is to prevent fraud, deception or misconduct against the Fund and to
provide reasonable standards of conduct.
Year 2000 Issues Many computer systems were designed in such a way that they may
be unable to distinguish between the year 2000

                                       13
<PAGE>
and the year 1900 (commonly known as the 'Year 2000 Problem'). The year 2000
problem may adversely affect the issuers of the securities contained in the
Portfolio, but we cannot predict whether any impact will be material to the
Portfolio as a whole. We do not expect that the computer system changes
necessary to prepare for the Year 2000 will cause any major operational
difficulties for the Fund. The Year 2000 Problem may adversely affect the
issuers of the securities contained in the Portfolio, but we cannot predict
whether any impact will be material to the Portfolio as a whole.
TAXES THE FOLLOWING SUMMARY DESCRIBES SOME OF THE IMPORTANT INCOME TAX
CONSEQUENCES OF HOLDING UNITS. IT ASSUMES THAT YOU ARE NOT A DEALER, FINANCIAL
INSTITUTION, INSURANCE COMPANY OR OTHER INVESTOR WITH SPECIAL CIRCUMSTANCES. YOU
SHOULD CONSULT YOUR OWN TAX ADVISER ABOUT YOUR PARTICULAR CIRCUMSTANCES.
IN THE OPINION OF OUR COUNSEL, UNDER EXISTING LAW: GENERAL TREATMENT OF THE FUND
AND YOUR INVESTMENT THE FUND WILL NOT BE TAXED AS A CORPORATION FOR FEDERAL
INCOME TAX PURPOSES, AND YOU
WILL BE CONSIDERED TO OWN DIRECTLY YOUR SHARE OF EACH BOND IN THE FUND.
INCOME OR LOSS UPON DISPOSITION WHEN ALL OR PART OF YOUR SHARE OF A BOND IS
DISPOSED OF (FOR EXAMPLE, WHEN THE FUND SELLS, EXCHANGES OR REDEEMS A BOND OR
WHEN YOU SELL OR EXCHANGE YOUR UNITS), YOU WILL GENERALLY RECOGNIZE CAPITAL GAIN
OR LOSS. YOUR GAIN, HOWEVER, WILL GENERALLY BE ORDINARY INCOME TO THE EXTENT OF
ANY ACCRUED 'MARKET DISCOUNT'. GENERALLY YOU WILL HAVE MARKET DISCOUNT TO THE
EXTENT THAT YOUR BASIS IN A BOND WHEN YOU PURCHASE A UNIT IS LESS THAN ITS
STATED REDEMPTION PRICE AT MATURITY (OR, IF IT IS AN ORIGINAL ISSUE DISCOUNT
BOND, THE ISSUE PRICE INCREASED BY ORIGINAL ISSUE DISCOUNT THAT HAS ACCRUED ON
THE BOND BEFORE YOUR PURCHASE). YOU SHOULD CONSULT YOUR TAX ADVISER IN THIS
REGARD.
IF YOUR NET LONG-TERM CAPITAL GAINS EXCEED YOUR NET SHORT-TERM CAPITAL LOSSES,
THE EXCESS MAY BE SUBJECT TO TAX AT A LOWER RATE THAN ORDINARY INCOME. ANY
CAPITAL GAIN FROM THE FUND WILL BE LONG-TERM IF YOU ARE CONSIDERED TO HAVE HELD
YOUR INVESTMENT ON EACH BOND FOR MORE THAN ONE YEAR AND SHORT-TERM IF YOU HELD
IT FOR ONE YEAR OR LESS. BECAUSE THE DEDUCTIBILITY OF CAPITAL LOSSES IS SUBJECT
TO LIMITATIONS, YOU MAY NOT BE ABLE TO DEDUCT ALL OF YOUR CAPITAL LOSSES. YOU
SHOULD CONSULT YOUR TAX ADVISOR IN THIS REGARD.
YOUR BASIS IN THE BONDS YOUR AGGREGATE BASIS IN THE BONDS WILL BE EQUAL TO THE
COST OF YOUR UNITS, INCLUDING ANY SALES CHARGES AND THE ORGANIZATIONAL EXPENSES
YOU PAY, ADJUSTED TO REFLECT ANY ACCRUALS OF 'ORIGINAL ISSUE DISCOUNT,'
'ACQUISITION PREMIUM' AND 'BOND

                                       14
<PAGE>
PREMIUM'. YOU SHOULD CONSULT YOUR TAX ADVISER IN THIS REGARD.
EXPENSES IF YOU ARE AN INDIVIDUAL WHO ITEMIZES DEDUCTIONS, YOU MAY DEDUCT YOUR
SHARE OF FUND EXPENSES, BUT ONLY TO THE EXTENT THAT SUCH AMOUNT, TOGETHER WITH
YOUR OTHER MISCELLANEOUS DEDUCTIONS, EXCEEDS 2% OF YOUR ADJUSTED GROSS INCOME.
YOUR ABILITY TO DEDUCT FUND EXPENSES WILL BE LIMITED FURTHER IF YOUR ADJUSTED
GROSS INCOME EXCEEDS A SPECIFIED AMOUNT (FOR 1999, $126,600 OR $63,300 FOR A
MARRIED PERSON FILING SEPARATELY).
FOREIGN INVESTORS IF YOU ARE A FOREIGN INVESTOR AND YOU ARE NOT ENGAGED IN A
U.S. TRADE OR BUSINESS, YOU GENERALLY WILL NOT BE SUBJECT TO U.S. FEDERAL INCOME
TAX, INCLUDING WITHHOLDING TAX, ON THE INTEREST OR GAIN ON A BOND ISSUED AFTER
JULY 18, 1984 IF YOU MEET CERTAIN REQUIREMENTS, INCLUDING THE CERTIFICATION OF
FOREIGN STATUS AND OTHER MATTERS. YOU SHOULD CONSULT YOUR TAX ADVISER ABOUT THE
POSSIBLE APPLICATION OF FEDERAL, STATE AND LOCAL, AND FOREIGN TAXES.
SUPPLEMENTAL INFORMATION YOU CAN RECEIVE AT NO COST SUPPLEMENTAL INFORMATION
ABOUT THE FUND BY CALLING THE TRUSTEE. THE SUPPLEMENTAL INFORMATION INCLUDES
MORE DETAILED RISK DISCLOSURE ABOUT THE TYPES OF BONDS THAT MAY BE IN THE FUND'S
PORTFOLIO, GENERAL RISK DISCLOSURE CONCERNING ANY INSURANCE SECURING CERTAIN
BONDS, AND GENERAL INFORMATION ABOUT THE STRUCTURE AND OPERATION OF THE FUND.
THE SUPPLEMENTAL INFORMATION IS ALSO AVAILABLE FROM THE SEC.

DEFINED ASSET FUNDS


REPORT OF INDEPENDENT ACCOUNTANTS


The Sponsors, Trustee and Holders
  of Corporate Income Fund,
  Insured Series - 102,
  Defined Asset Funds:

We have audited the accompanying statement of condition of Corporate
Income Fund, Insured Series - 102, Defined Asset Funds, including the
portfolio, as of March 31, 1999 and the related statements of
operations and of changes in net assets for the period April 9, 1998
to March 31, 1999. These financial statements are the responsibility
of the Trustee. Our responsibility is to express an opinion on these
financial statements based on our audit.

We conducted our audit 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. Securities owned at March 31,
1999, as shown in such portfolio, were confirmed to us by The Bank of
New York, 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 audit provides 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 Corporate
Income Fund, Insured Series - 102, Defined Asset Funds at March 31,
1999 and the results of its operations and changes in its net assets
for the above-stated period in conformity with generally accepted
accounting principles.

  1.  SIGNIFICANT ACCOUNTING POLICIES

      The Fund is registered under the Investment Company Act of 1940 as
      a Unit Investment Trust. The following is a summary of significant
      accounting policies consistently followed by the Fund in the
      preparation of its financial statements. The policies are in
      conformity with generally accepted accounting principles.

      (a) Securities are stated at value as determined by the Evaluator
          based on bid side evaluations for the securities, except that
          value on April 9, 1998 was based upon offer side evaluations
          at April 7, 1998 the day prior to the Date of Deposit. Cost
          of securities at April 9, 1998 was also based on such offer
          side evaluations; the cost of securities deposited
          subsequently is based on offer side evaluations at date
          of purchase.

      (b) The Fund is not subject to income taxes. Accordingly, no
          provision for such taxes is required.

      (c) Interest income is recorded as earned.

  2.  DISTRIBUTIONS

      A distribution of net investment income is made to Holders each
      month. Receipts other than interest, after deductions for
      redemptions and applicable expenses, are also distributed
      periodically.

  5.  DEFERRED SALES CHARGE

      The sales charges are being paid for with the principal proceeds
      from periodic sale or maturity of the segregated bonds. A deferred
      sales charge of $5.00 per unit is charged three times in the first
      year and $3.75 per unit on a quarterly basis for the second and
      third years, and paid to the Sponsors annually by the Trustee on
      behalf of the Holders, up to an aggregate of $45.00 per unit over
      the first three years of the life of the Fund. Should a Holder
      redeem units prior to the third anniversary of the Fund, the
      remaining balance of the deferred sales charge will be charged.

  6.  DEFERRED ORGANIZATIONAL COSTS

      Organizational costs have been deferred and are being amortized over
      five years.

CORPORATE INCOME FUND,
INSURED SERIES - 102,
DEFINED ASSET FUNDS


NOTES TO PORTFOLIO
AS OF MARCH 31, 1999

   (1) "NR", if applicable, indicates that this security is not
       currently rated by the indicated rating service. These ratings
       have been provided by the Evaluator, but not confirmed with the
       rating agencies.

   (2) See Notes to Financial Statements.

   (3) Optional redemption provisions, which may be exercised in whole
       or in part, are initially at prices of par plus a premium, then
       subsequently at prices declining to par. Certain securities may
       provide for redemption at par prior or in addition to any
       optional or mandatory redemption dates or maturity, for
       example, through the operation of a maintenance and replacement
       fund, if proceeds are not able to be used as contemplated, the
       project is condemned or sold or the project is destroyed and
       insurance proceeds are used to redeem the securities. Many of
       the securities are also subject to mandatory sinking fund
       redemption commencing on dates which may be prior to the date
       on which securities may be optionally redeemed. Sinking fund
       redemptions are at par and redeem only part of the issue. Some
       of the securities have mandatory sinking funds which contain
       optional provisions permitting the issuer to increase the
       principal amount of securities called on a mandatory redemption
       date. The sinking fund redemptions with optional provisions
       may, and optional refunding redemptions generally will, occur
       at times when the redeemed securities have an offering side
       evaluation which represents a premium over par. To the extent
       that the securities were acquired at a price higher than the
       redemption price, this will represent a loss of capital when
       compared with the Public Offering Price of the Units when
       acquired. Distributions will generally be reduced by the amount
       of the income which would otherwise have been paid with respect
       to redeemed securities and there will be distributed to Holders
       any principal amount and premium received on such redemption
       after satisfying any redemption requests for Units received by
       the Fund. The estimated current return may be affected by
       redemptions.

   (4) It is anticipated that principal received from these bonds will
       be applied to the payment of the Trust's deferred sales charges.

                                         When units of this Fund are no longer
                                         available, this Prospectus may be used
                                         as a preliminary prospectus for a
                                         future series, but some of the
                                         information in this Prospectus will be
                                         changed for that series.
                                         Units of any future series may not be
                                         sold nor may offers to buy be accepted
                                         until that series has become effective
                                         with the Securities and Exchange
                                         Commission. No units can be sold in any
                                         State where a sale would be illegal.
