                SUBJECT TO COMPLETION, DATED AUGUST 5, 1999

PROSPECTUS
                                5,000,000 DECS/SM/
                                  DECS Trust V
  (Subject to Exchange into Common Stock of Crown Castle International Corp.)

                                   --------

  DECS Trust V is a recently created Delaware business trust. The DECS are
securities that represent all of the beneficial interest in the trust. When the
trust issues the DECS, it will acquire U.S. Treasury securities and four
prepaid forward contracts for the purchase of Crown Castle common stock.


  For each DECS that you buy, you will receive a cash distribution of $  on
each    ,    ,     and     starting on     , 1999 and ending on     , 2002.
Those payments will be made from the U.S. Treasury securities that the trust
acquires when it issues the DECS.

  The trust will hold four prepaid forward contracts, each of which will
entitle the trust to receive Crown Castle common stock or cash from one of four
stockholders of Crown Castle. We refer to those four stockholders as the
sellers. On or shortly after     , 2002, each seller will deliver, at its
option, either cash or Crown Castle common stock to the trust. The trust will
then deliver this cash or Crown Castle common stock to you. Under the
circumstances described in this prospectus, each seller will have the option to
deliver cash to the trust between     , 2002 and     , 2002. After the trust
has delivered to you the cash or Crown Castle common stock delivered to the
trust by all of the sellers, the trust will terminate. The amount of cash or
number of shares of Crown Castle common stock each seller will deliver and you
will receive will depend on the price of Crown Castle common stock shortly
before the date the seller delivers the cash or Crown Castle common stock to
the trust. If the price of Crown Castle common stock is:

  . more than $  per share, you will receive 0.  shares of Crown Castle common
    stock, or the cash equivalent, for each DECS you own

  . more than $   per share but less than or equal to $  per share, you will
    receive Crown Castle common stock worth $   , or the cash equivalent, for
    each DECS you own

  . $  per share or less, you will receive one share of Crown Castle common
    stock, or the cash equivalent, for each DECS you own

  The last reported sale price of Crown Castle common stock on August 4, 1999
was $22.00 per share.

  The trust's securities have no history of public trading. Typical closed-end
fund shares frequently trade at a discount from net asset value. This
characteristic of investments in a closed-end investment company is a risk
separate and distinct from the risk that the trust's net asset value will
decrease. The trust cannot predict whether the DECS will trade at, below or
above net asset value. The risk of purchasing investments in a closed-end
company that might trade at a discount is more pronounced for investors who
wish to sell their investments soon after completion of a public offering.

                                   --------

Investing in the DECS involves certain risks. See "Risk Factors for DECS"
beginning on page 22.

  Neither the Securities and Exchange Commission nor any state securities
commission has approved or disapproved of these securities or determined if
this prospectus is truthful or complete. Any representation to the contrary is
a criminal offense.

                               PROSPECTUS SUMMARY

   This summary highlights certain information contained elsewhere in this
prospectus. This summary is not complete and does not contain all of the
information that you should consider before investing in the DECS. You should
read the entire prospectus carefully, especially the risks of investing in the
DECS discussed under "Risk Factors for DECS."

                                   The Trust

   DECS Trust V is a recently created Delaware business trust. The trust will
terminate on or shortly after     , 2002, which is referred to in this summary
as the "exchange date" because that is when the Crown Castle common stock or
their value in cash are expected to be delivered under all of the prepaid
forward contracts the trust has with the sellers. In some limited
circumstances, the Crown Castle common stock or its value in cash may be
delivered and the trust terminated sooner than that date. In other limited
circumstances, one or more sellers who elect to deliver cash may extend the
exchange date, for purposes of their respective contracts only, to     , 2002,
and may subsequently accelerate the extended exchange date if they wish. If the
exchange date under any of the sellers' contracts is extended in this way, the
trust will terminate on or shortly after the date all of the Crown Castle
common stock or cash has been delivered under all of the prepaid forward
contracts.

                                    The DECS

   The DECS are securities that represent all of the beneficial interest in the
trust. The underwriters named in this prospectus are offering the DECS for sale
at a price of $    per DECS, which is the same as the closing bid price of a
share of Crown Castle common stock on the Nasdaq National Market on     , 1999.
The underwriters also may purchase up to 645,000 additional DECS from the trust
to cover over-allotments.

                              Purpose of the Trust

   The trust was created to issue the DECS and to carry out the transactions
described in this prospectus. The terms of the DECS are designed to give you a
higher yield than the current dividend yield on Crown Castle common stock,
while also giving you the chance to share in the increased value of Crown
Castle common stock if its price goes up. Crown Castle does not currently pay
dividends on its common stock and has stated that it does not intend to do so,
but in the future Crown Castle might pay dividends that are higher than the
distributions that you will receive from the trust. Also, you will receive less
than you paid for your DECS if the price of Crown Castle common stock goes
down, but you will receive only part of the increased value if the price goes
up, and then only if the price is above $   per share shortly before the
exchange date.

                            Quarterly Distributions

   For each DECS that you buy, you will receive a cash distribution of $   on
each    ,    ,     and    , starting on     , 1999 and ending on     , 2002.
Those payments will be made from the U.S. Treasury securities that the trust
acquires when it issues the DECS.

                       Distributions on the Exchange Date

   On the exchange date, you will receive between 0.   and 1.0 shares of Crown
Castle common stock for each DECS you own. Those amounts will be adjusted if
Crown Castle splits its stock, pays a stock dividend, issues warrants or
distributes certain types of assets or if certain other events occur that are
described in detail

                                       3
<PAGE>

later in this prospectus. Under its prepaid forward contract with the trust,
each seller has the option to deliver cash to the trust instead of shares of
Crown Castle common stock. If a seller decides to deliver cash, you will
receive the cash value of the Crown Castle common stock you would have received
under that seller's contract instead of the shares themselves. If Crown Castle
merges into another company or liquidates, you may receive shares of the other
company or cash instead of Crown Castle common stock on the exchange date. And
if a seller defaults under its prepaid forward contract with the trust, the
obligations of that seller under its contract will be accelerated, and the
trust will immediately distribute to you the Crown Castle common stock or cash
received by the trust under the relevant prepaid forward contract, plus a
proportionate amount of the U.S. Treasury securities then held by the trust.

   In addition, each seller may elect to deliver cash instead of Crown Castle
common stock by completing an offering of securities to refinance the DECS. We
refer to such an offering as a rollover offering. Each seller may extend the
exchange date under its prepaid forward contract to     , 2002, but only in
connection with a rollover offering. If any seller completes a rollover
offering and has extended the exchange date, that seller will deliver the cash
due under its prepaid forward contract by the fifth business day after the
extended exchange date. Any sellers that have elected to extend the exchange
date to     , 2002 will also have the option of later accelerating the exchange
date to between     , 2002 and     , 2002, in which case such sellers will
deliver the cash due under their prepaid forward contracts by the fifth
business day after the accelerated exchange date.

   In addition, any seller that has extended the exchange date will deliver
cash to be distributed as an additional partial distribution for the period
beginning on     , 2002 and ending on the date the seller delivers the cash
value of the Crown Castle common stock under its prepaid forward contract.

                                 Voting Rights

   You will not have the right to vote any Crown Castle common stock unless and
until it is delivered to the trust by the sellers and distributed to you by the
trust. You will have the right to vote on matters that affect the trust.

            Assets of the Trust; Investment Objectives and Policies

   The trust will own the following assets:

  .  zero-coupon U.S. Treasury securities that will mature every quarter
     during the term of the trust, and which will provide cash to pay the
     quarterly distributions on the DECS

  .  a prepaid forward contract with each of the sellers under which each
     relevant seller has the right to deliver Crown Castle common stock or
     cash to the trust on the exchange date, which the trust will then
     distribute to you

The U.S. Treasury securities initially will represent approximately   % of the
trust's assets and the prepaid forward contracts initially will represent
approximately   %.

   The trust's investment objective is to provide you with (1) a quarterly
distribution of $    per DECS over the term of the trust and (2) Crown Castle
common stock on the exchange date in an amount equal to:

  .  0.   shares of Crown Castle common stock per DECS if the average price
     of Crown Castle common stock shortly before the exchange date is more
     than $

                                       4
<PAGE>


  .  shares of Crown Castle common stock worth $   per DECS (the issue price
     of the DECS) if the average price of Crown Castle common stock shortly
     before the exchange date is more than $   per share but less than or
     equal to $   per share

  .  one share of Crown Castle common stock per DECS if the average price of
     Crown Castle common stock shortly before the exchange date is $   or
     less per share

The trust will not deliver fractions of a share of Crown Castle common stock.
If you would receive a fraction of a share of Crown Castle common stock under
this formula (based on all DECS owned), you will receive cash instead.

   At the closing of the sale of the DECS, the trust will enter into prepaid
forward contracts with each of the sellers. The prepaid forward contracts will
require the sellers to deliver to the trust up to a total of     shares of
Crown Castle common stock on the exchange date for all of the contracts
together. The purchase price for the Crown Castle common stock under each
prepaid forward contract will be $   per share or $   in total for all of the
contracts together. The trust will pay the sellers the purchase price for the
Crown Castle common stock on the date the DECS are issued.

   Each seller will secure its obligations to deliver Crown Castle common stock
to the trust on the exchange date by pledging the stock to the trust on the
date the DECS are issued. During the term of the DECS, two of the sellers will
have the right to substitute U.S. Treasury securities as collateral for their
pledged Crown Castle common stock.

   Any seller electing to extend the exchange date under its contract to     ,
2002 will secure its obligation to pay interest accruing during the period
beginning on     , 2002 and ending on the extended (or accelerated) exchange
date by pledging U.S. Treasury securities to the trust.

                  Certain U.S. Federal Income Tax Consequences

   For U.S. federal income tax purposes, the trust and owners of DECS agree to
treat the owners of DECS as owning all of the beneficial interests in the U.S.
Treasury securities and the prepaid forward contracts held by the trust. In
addition, the sellers, the trust and owners of DECS agree to treat a portion of
the amount invested by you as a cash deposit that will be used to satisfy your
obligation to make payment under the prepaid forward contracts for the purchase
of Crown Castle common stock on the exchange date. Under this treatment, if you
are a U.S. individual or taxable entity, you generally will be required to pay
taxes on only a relatively small portion of each quarterly cash distribution
you receive from the trust, which will be ordinary income. If you hold the DECS
until they mature, you will not be subject to tax on the receipt of Crown
Castle common stock. If you sell your DECS or receive cash on the exchange
date, you will have a capital gain or loss equal to the difference between your
tax basis in the DECS and the cash you receive. In addition, it is possible
that you will have a capital gain on a deemed exchange of a portion of your
DECS during the term of the DECS. You should refer to the section "Certain
United States Federal Income Tax Considerations" in this prospectus for more
information.

   Crown Castle is a leading owner and operator of towers and transmission
networks for wireless communications and broadcast companies.

   A prospectus and a prospectus supplement that describe Crown Castle and the
Crown Castle common stock that you may receive are attached to this prospectus.
Crown Castle is not affiliated with the trust, will not receive any of the
proceeds from the sale of the DECS by the trust and will not have any
obligation under the

DECS or the prepaid forward contracts between the trust and the sellers. The
sellers did not prepare, and are not responsible for, the Crown Castle
prospectus or prospectus supplement. The Crown Castle prospectus and prospectus
supplement are attached to this prospectus only for your convenience. The Crown
Castle prospectus and prospectus supplement are not part of this prospectus and
are not incorporated by reference into this prospectus.

                   Management and Administration of the Trust

   The internal operations of the trust will be managed by three trustees; the
trust will not have an investment advisor. The Bank of New York (or its
successor) will act as trust administrator to carry out the day-to-day
administration of the trust, and will also be the custodian for the trust's
assets, its paying agent, registrar and transfer agent for the DECS and the
collateral agent for the sellers' pledges of Crown Castle common stock to the
trust. The Bank of New York will not have any other affiliation with the trust.

                               Term of the Trust

   The trust will terminate automatically on or shortly after the date on which
the trust distributes to you the Crown Castle common stock or cash that the
trust receives on the exchange date under its prepaid forward contracts with
the sellers. Under most circumstances, this will be on or shortly after     ,
2002 or     , 2002 if any seller has elected to extend the exchange date under
its contract.

                                  Risk Factors

  .  The trust will not dispose of its prepaid forward contracts for Crown
     Castle common stock during the term of the trust even if the value of
     Crown Castle common stock declines or Crown Castle's financial condition
     changes for the worse.

  .  During the term of the trust, Crown Castle could start paying dividends
     that would provide investors in its stock with a higher yield than you
     will receive on the DECS.

  .  You will bear the entire risk of declines in the value of Crown Castle
     common stock between the closing date and the exchange date. The amount
     of Crown Castle common stock or cash that you will receive on the
     exchange date is not fixed, but is based on the market price of Crown
     Castle common stock shortly before the exchange date. If the market
     price of Crown Castle common stock declines, the stock or cash that you
     receive will be less than what you paid for your DECS and you will lose
     money. If Crown Castle becomes bankrupt or insolvent, you could lose
     everything you paid for your DECS.

  .  You will have less opportunity for gains if the value of Crown Castle
     common stock increases than you would have if you purchased Crown Castle
     common stock directly. You will realize a gain only if the value of
     Crown Castle common stock increases by approximately  % between the
     closing date and the exchange date, and then you will only receive  % of
     the increase in the Crown Castle common stock price above that level.
     Because the trust will determine the value of the Crown Castle common
     stock based on its average price for 20 trading days before the exchange
     date, the actual value of the stock or cash that you receive on the
     exchange date may be more or less than the price of the stock on the
     exchange date.

  .  Because the trust will own only U.S. Treasury securities and the prepaid
     forward contracts, an investment in the DECS may be riskier than an
     investment in an investment company with more diversified assets.

                                       6
<PAGE>


  .  The trading price of Crown Castle common stock will directly affect the
     trading price of the DECS in the secondary market. The trading price of
     Crown Castle common stock will be influenced by Crown Castle's operating
     results and prospects, by economic, financial and other factors and by
     general market conditions.

  .  You will not have any right to vote the Crown Castle common stock
     underlying the DECS, to receive dividends on that stock (if any are
     declared) or to act as an owner of the stock in any other way unless and
     until the sellers deliver the stock to the trust under their prepaid
     forward contracts and the trust distributes the stock to you.

  .  A bankruptcy of any of the sellers could interfere with the timing of
     the delivery of shares or cash under the DECS and therefore could affect
     the amount you receive.

                                    Listing

   The trust has applied to have the DECS approved for listing on the Nasdaq
National Market under the symbol " TWDE." Crown Castle common stock is traded
on the Nasdaq National Market under the symbol "TWRS." The last reported sale
price of Crown Castle common stock on August 14, 1999 was $22.00 per share.

                               FEES AND EXPENSES

   Because the trust will use proceeds from the sale of the DECS to purchase
the forward contracts from the sellers, the sellers have agreed in the
underwriting agreement to pay to the underwriters as compensation $   per DECS.
See "Underwriting." Salomon Smith Barney Inc. ("Salomon Smith Barney") will pay
estimated organization costs of the trust in the aggregate amount of $   and
estimated costs of the trust in connection with the initial registration and
public offering of the DECS in the aggregate amount of $   at the closing of
this offering. In addition, Salomon Smith Barney will pay the Administrator,
the Custodian, the Paying Agent and each Trustee at the closing of this
offering a one-time, up-front amount in respect of its ongoing fees and, in the
case of the Administrator, anticipated expenses of the trust (estimated to be
$   in the aggregate) over the term of the trust. Salomon Smith Barney has
agreed to pay any on-going expenses of the trust in excess of these estimated
amounts and to reimburse the trust for any amounts it may be required to pay as
indemnification to any Trustee, the Administrator, the Custodian or the Paying
Agent. The sellers will reimburse Salomon Smith Barney for certain expenses of
the trust and reimbursements of indemnifications paid by it. See "Management
and Administration of the Trust--Estimated Expenses."

   Regulations of the Securities and Exchange Commission require the
presentation of trust expenses in the following format in order to assist
investors in understanding the costs and expenses that an investor will bear
directly or indirectly. Because the trust will not bear any ongoing fees or
expenses, investors will not bear any direct expenses. The only expenses that
an investor might be considered to bear indirectly are (a) the underwriters'
compensation payable by the sellers with respect to such investor's DECS and
(b) the ongoing expenses of the trust (including fees of the Administrator,
Custodian, Paying Agent and Trustees), estimated at $   per year in the
aggregate, which Salomon Smith Barney will pay at the closing of the offering.

                                   THE TRUST

   DECS Trust V is a newly organized Delaware business trust that is registered
as a closed-end management investment company under the Investment Company Act.
The trust was formed on April 22, 1999, pursuant to a Declaration of Trust,
dated as of April 22, 1999 (the "Declaration of Trust"). The term of the trust
will expire on or shortly after   , 2002, except that the trust may be
dissolved prior to such date under certain limited circumstances. The address
of the trust is c/o Salomon Smith Barney Inc., 388 Greenwich Street, New York,
New York 10013 (telephone number: (212) 816-6000).

                                USE OF PROCEEDS

   On or shortly after the date on which it sells the DECS, the trust will use
the proceeds of this offering to purchase a fixed portfolio comprised of a
series of zero-coupon U.S. Treasury securities (the "Treasury Securities")
maturing quarterly during the term of the trust and to pay the purchase price
under each prepaid forward contract (the "prepaid forward contract") to the
relevant seller.

                       INVESTMENT OBJECTIVES AND POLICIES

Trust Assets

   The trust's investment objectives are to provide investors with a quarterly
distribution of $   per DECS on each distribution date during the term of the
trust (representing the pro rata portion of the quarterly distributions in
respect of the maturing Treasury Securities held by the trust) and to provide
investors, on   , 2002 or such later date not later than   , 2002 as may be
elected by one or more sellers making a Rollover Offering as described below
(in each case, the "Exchange Date" under the applicable prepaid forward
contract or contracts), a number of shares of Crown Castle common stock (the
"Common Stock") at the Exchange Rate (as defined below) or, to the extent that
one or more sellers elects the Cash Delivery Option (as defined below), an
amount in cash equal to the Exchange Price (as defined below) thereof. On or
prior to the 25th Business Day prior to the Exchange Date, each seller will
notify the trust concerning its exercise of the Cash Delivery Option, and the
trust in turn will notify The Depository Trust Company and publish a notice in
a daily newspaper of national circulation stating whether investors will
receive shares of Common Stock, cash or both. See "--The Forward Contracts--
General" below. "Business Day" means any day that is not a Saturday, a Sunday
or a day on which the New York Stock Exchange (the "NYSE") or banking
institutions or trust companies in The City of New York are authorized or
obligated by law or executive order to close.

   The "Exchange Rate" is equal to, subject to certain adjustments,

  (a) if the Exchange Price (as defined below) is greater than $   (the
      "Threshold Appreciation Price"), shares of Common Stock per DECS;

  (b) if the Exchange Price is less than or equal to the Threshold
      Appreciation Price but is greater than $   (the "Initial Price"), a
      fraction, equal to the Initial Price divided by the Exchange Price, of
      one share of Common Stock per DECS; and

  (c) if the Exchange Price is less than or equal to the Initial Price, one
      share of Common Stock per DECS.

   Accordingly, the value of the Common Stock to be received by investors (or,
as discussed below, the cash equivalent to be received in lieu of such Common
Stock) at the Exchange Date will not necessarily equal the Initial Price. The
numbers of shares of Common Stock per DECS specified in clauses (a), (b) and
(c) of the Exchange Rate are hereinafter referred to as the "Share Components."
Any shares of Common Stock delivered by the trust to investors that are not
affiliated with Crown Castle will be free of any transfer restrictions and the
investors will be responsible for the payment of all brokerage costs upon the
subsequent

                                       9
<PAGE>

sale of such shares. Investors otherwise entitled to receive fractional shares
in respect of their aggregate holdings of DECS will receive cash in lieu
thereof. See "--Delivery of Common Stock and Reported Securities; No Fractional
Shares of Common Stock or Reported Securities" below. Notwithstanding the
foregoing, (1) in the case of certain dilution events, the Exchange Rate will
be subject to adjustment and (2) in the case of certain adjustment events, the
consideration received by investors at the Exchange Date will be cash or
Reported Securities (as defined herein) or a combination thereof, rather than
(or in addition to) shares of Common Stock. See "--The Forward Contracts--
Dilution Adjustments" and "--The Forward Contracts--Adjustment Events" below.

   The trust has adopted a fundamental policy to invest at least 65% of its
portfolio in the prepaid forward contracts. The prepaid forward contracts will
comprise approximately   % of the trust's initial assets. The trust has also
adopted a fundamental policy that the trust may not dispose of the prepaid
forward contracts during the term of the trust and that the trust may not
dispose of the Treasury Securities held by the trust prior to the earlier of
their respective maturities and the termination of the trust except for the
partial liquidation of Treasury Securities following acceleration of one or
more prepaid forward contracts as described below under "--The Treasury
Securities." These fundamental policies of the trust may not be changed without
the vote of a "majority in interest" of the owners of the DECS. A "majority in
interest" means the lesser of (a) 67% of the DECS represented at a meeting at
which more than 50% of the outstanding DECS are represented and (b) more than
50% of the outstanding DECS.

   The "Exchange Price" under any prepaid forward contract means the average
Closing Price (as defined below) per share of Common Stock on the 20 Trading
Days immediately prior to (but not including) the Exchange Date thereunder;
provided, however, that if there are not 20 Trading Days (as defined below) for
the Common Stock occurring later than the 60th calendar day immediately prior
to, but not including, the Exchange Date, the Exchange Price will be the market
value per share of Common Stock as of the Exchange Date as determined by a
nationally recognized independent investment banking firm that the
Administrator retains for this purpose. The Exchange Price will be calculated
in a different manner if the relevant seller carries out a Rollover Offering
(as defined below), as described under "--Rollover Offerings." The "Closing
Price" of any security on any date of determination means:

  (1) the closing sale price (or, if no closing price is reported, the last
      reported sale price) of such security (regular way) on the NYSE on such
      date,

  (2) if such security is not listed for trading on the NYSE on any such
      date, as reported in the composite transactions for the principal
      United States securities exchange on which such security is so listed,

  (3) if such security is not so listed on a United States national or
      regional securities exchange, as reported by The Nasdaq Stock Market,

  (4) if such security is not so reported, the last quoted bid price for such
      security in the over-the-counter market as reported by the National
      Quotation Bureau or similar organization, or

  (5) if such security is not so quoted, the average of the mid-point of the
      last bid and ask prices for such security from at least three
      nationally recognized investment banking firms that the Administrator
      selects for such purpose.

   A "Trading Day" is defined as a day on which the security the Closing Price
of which is being determined (A) is not suspended from trading on any national
or regional securities exchange or association or over-the-counter market at
the close of business and (B) has traded at least once on the national or
regional securities exchange or association or over-the-counter market that is
the primary market for the trading of such security.

   For illustrative purposes only, the following chart shows the number of
shares of Common Stock or the amount of cash that an investor would receive for
each DECS at various Exchange Prices. The chart assumes that there will be no
adjustments to the Exchange Rate due to any of the events described under "--
The

                                       10
<PAGE>

Forward Contracts--Dilution Adjustments" and "--The Forward Contracts--
Adjustment Events" below and that the prepaid forward contracts will not be
accelerated. There can be no assurance that the Exchange Price will be within
the range set forth below. Given the Initial Price of $   per DECS and the
Threshold Appreciation Price of $   , an investor would receive at the
Exchange Date the following number of shares of Common Stock or amount of cash
(if all sellers exercise the Cash Delivery Option) per DECS:

</TABLE>

   As the foregoing chart illustrates, if at the Exchange Date, the Exchange
Price is greater than $   , the trust will be obligated to deliver    shares
of Common Stock per DECS, resulting in an investor receiving only percent of
the appreciation in market value above $   . If at the Exchange Date, the
Exchange Price is greater than $   and less than or equal to $   , the trust
will be obligated to deliver only a fraction of a share of Common Stock having
a value at the Exchange Price equal to $   , resulting in an investor
receiving none of the appreciation in market value. If at the Exchange Date,
the Exchange Price is less than or equal to $   , the trust will be obligated
to deliver one share of Common Stock per DECS, regardless of the market price
of such share, resulting in an investor realizing the entire loss on the
decline in market value of the Common Stock.

   The following table sets forth information regarding the distributions to
be received on the Treasury Securities held by the trust, the portion of each
year's distributions that will constitute a return of capital for U.S. federal
income tax purposes and the amount of original issue discount accruing on the
Treasury Securities with respect to an investor who acquires its DECS at the
Initial Price from the underwriters in the original offering. See "Certain
United States Federal Income Tax Considerations."

   The trust will pay the annual distribution of $      per DECS quarterly on
each   ,   ,    and    (or, if any such date is not a Business Day, on the
next succeeding Business Day), commencing    , 1999. Quarterly distributions
on the DECS will consist solely of the cash received from the
Treasury Securities. The trust will not be entitled to any dividends that may
be declared on the Common Stock.

Enhanced Yield; Less Potential for Equity Appreciation than Common Stock; No
 Depreciation Protection

   The yield on the DECS is higher than the current dividend yield on the
Common Stock, which currently does not pay dividends. However, there is no
assurance that the yield on the DECS will be higher than the dividend yield on
the Common Stock over the term of the trust. In addition, the opportunity for
equity appreciation afforded by an investment in the DECS is less than the
opportunity for equity appreciation afforded by a direct investment in the
Common Stock because the value of the Common Stock to be received by owners of
the DECS at the Exchange Date (the "Amount Receivable at the Exchange Date")
will generally exceed the Initial Price only if the Exchange Price exceeds the
Threshold Appreciation Price (which represents an appreciation of   % over the
Initial Price) and because investors will be entitled to receive at the
Exchange Date only   % (the percentage equal to the Initial Price divided by
the Threshold Appreciation Price) of any appreciation of the value of the
Common Stock in excess of the Threshold Appreciation Price. Moreover, DECS
investors will bear the entire decline in value if the Exchange Price on the
Exchange Date is less than the Initial Price. Additionally, because the
Exchange Price is generally determined based on a 20

                                      11
<PAGE>

Trading Day average, the value of a share of Common Stock distributed on the
Exchange Date may be more or less than the Exchange Price used to determine the
Amount Receivable at the Exchange Date.

Crown Castle

   Crown Castle is a leading owner and operator of towers and transmission
networks for wireless communications and broadcast companies. A prospectus and
prospectus supplement that describe Crown Castle and the Common Stock that
owners of DECS may receive are attached to this prospectus.

   Owners of DECS will not be entitled to any rights with respect to the Common
Stock (including, without limitation, voting rights and rights to receive
dividends or other distributions in respect thereof) unless and until such
time, if any, as the sellers deliver shares of Common Stock to the trust
pursuant to the prepaid forward contracts and the trust has distributed such
shares to the owners of the DECS.

   The Common Stock has been listed on The Nasdaq National Market under the
symbol "TWRS" since August 18, 1998. The following table sets forth, for the
indicated periods, the high and low sales prices of the Common Stock, as
reported on The Nasdaq National Market. Crown Castle has never paid cash
dividends on the Common Stock and has stated that it does not anticipate paying
cash dividends on the Common Stock in the foreseeable future. As of   , 1999,
there were    recordholders of the Common Stock. Crown Castle's fiscal year end
is December 31.

   Crown Castle is not affiliated with the trust, will not receive any of the
proceeds from the sale of the DECS by the trust and will have no obligations
with respect to the DECS or the prepaid forward contracts. This prospectus
relates only to the DECS offered hereby and does not relate to Crown Castle or

with respect to the shares of Common Stock that may be delivered to the trust
by the sellers, and by the trust to the owners of DECS, at the Exchange Date or
upon earlier acceleration of any of the prepaid forward contracts. The
prospectus and prospectus supplement of Crown Castle constituting a part of
such registration statement include information relating to Crown Castle and
the Common Stock, including certain risk factors relevant to an investment in
the Common Stock. The prospectus and prospectus supplement of Crown Castle are
being attached hereto and delivered to prospective purchasers of DECS together
with this prospectus for convenience of reference only. The Crown Castle
prospectus and prospectus supplement are not part of this prospectus, and are
not incorporated by reference into this prospectus. The sellers did not
prepare, and are not responsible for, the Crown Castle prospectus or prospectus
supplement.

The Forward Contracts

   General. The trust will enter into the prepaid forward contracts with the
sellers obligating each seller to deliver to the trust at the Exchange Date
under its prepaid forward contract a number of shares of Common Stock equal to
the initial number of shares of Common Stock subject to the prepaid forward
contract multiplied by the Exchange Rate. The Exchange Rate is equal to,
subject to adjustment as described in "--Dilution Adjustments; Adjustment
Events" below,

  (1) if the Exchange Price is greater than the Threshold Appreciation Price,
        ;

  (2) if the Exchange Price is less than or equal to the Threshold
      Appreciation Price but greater than the Initial Price, the Initial
      Price divided by the Exchange Price; and

  (3) if the Exchange Price is less than or equal to the Initial Price, one.

                                       12

The purchase price under the prepaid forward contracts is equal to $   per
share of Common Stock and $   in total and is payable to the sellers by the
trust on the closing of this offering. The purchase price of the prepaid
forward contracts was arrived at by arm's length negotiations between the trust
and the sellers taking into consideration factors including the price, expected
dividend level and volatility of the Common Stock, current interest rates, the
term of the prepaid forward contracts, current market volatility generally, the
collateral pledged by the sellers to secure their obligations under their
respective prepaid forward contracts, the value of other similar instruments
and the costs and anticipated proceeds of the offering of the DECS. All matters
relating to the administration of the prepaid forward contracts will be the
responsibility of either the trust's Administrator or its Custodian.

   Although each seller currently intends to deliver shares of Common Stock at
the Exchange Date, each seller may, at its option, deliver cash in lieu of
delivering all, but not less than all, of the shares of Common Stock otherwise
deliverable by it on the Exchange Date (the "Cash Delivery Option"), except
where such delivery would violate applicable state law. The amount of cash
deliverable by any seller who exercises the Cash Delivery Option will be equal
to the product of the number of shares of Common Stock otherwise deliverable by
that seller on the Exchange Date multiplied by the Exchange Price. On or prior
to the 25th Business Day prior to the Exchange Date, each seller will notify
the trust concerning its exercise of the Cash Delivery Option, and the trust in
turn will notify The Depository Trust Company and publish a notice in a daily
newspaper of national circulation stating whether the owners of DECS will
receive shares of Common Stock or cash or both.

   Extension and Acceleration of the Exchange Date at the Option of
Sellers. Any seller that elects the Cash Delivery Option and is making a
Rollover Offering may extend the Exchange Date under its prepaid forward
contract to   , 2002. If a seller extends the Exchange Date, it will not be
required to deliver the cash value of the Common Stock under its prepaid
forward contract until   , 2002. However, once the seller extends the Exchange
Date, that seller can then accelerate the Exchange Date under its prepaid
forward contract to any date between   , 2002 and   , 2002. If any seller
extends or accelerates the Exchange Date under its prepaid forward contract,
the trust will receive the cash payable under that contract within five
Business Days after the extended or accelerated Exchange Date, and the amount
of cash will be calculated as of the extended or accelerated Exchange Date.

   Any seller extending the Exchange Date under its prepaid forward contract in
connection with a Rollover Offering must also deliver to the trust an
additional amount of cash on the extended or accelerated Exchange Date to be
distributed as an additional distribution to the holders of the DECS in respect
of the period between the originally scheduled Exchange Date and the Exchange
Date as so extended or accelerated. In addition, such seller will be required
to pledge U.S. Treasury securities to secure its obligation to deliver cash for
this additional distribution. See "--Collateral Requirements of the Forward
Contracts Acceleration." The amount of the additional distribution that would
be paid on the DECS would be equal to a portion of the regular quarterly
distribution on the DECS pro-rated to reflect the number of days by which the
Exchange Date is extended or accelerated and the proportion of all the Common
Stock covered by all of the prepaid forward contracts that are represented by
the prepaid forward contracts as to which the Exchange Date is being extended
or accelerated. For example, if the Exchange Date under all of the prepaid
forward contracts is extended to        , 2002 and then accelerated to        ,
2002 (i.e., two-thirds of the time between        , 2002 and         , 2002),
the additional distribution would be equal to two-thirds of the regular
quarterly distribution. If only forward purchase contracts representing one-
half of all of the Common Stock deliverable under the DECS are the subject of
the same extension and acceleration, then the additional distribution would be
equal to one-third of the regular quarterly distribution.

   If some sellers elect to extend the Exchange Date under their prepaid
forward contracts in connection with Rollover Offerings and others do not, then
the originally scheduled Exchange Date of   , 2002 will remain in effect for
the sellers who do not extend, the Exchange Price under those sellers' prepaid
forward contracts will be determined as described herein shortly before that
date, and the trust will distribute the cash and/or shares of Common Stock it
receives under those prepaid forward contracts to the holders of DECS on or

                                       13
<PAGE>

shortly after that date. All sellers who do extend the Exchange Date under
their prepaid forward contracts will be required to extend to   , 2002, and no
seller may then accelerate the Exchange Date under its prepaid forward contract
unless all sellers who have extended their Exchange Dates accelerate to the
same date. The Exchange Price under the accelerating sellers' prepaid forward
contracts will be calculated as described below immediately before the extended
or accelerated Exchange Date, and the trust will distribute the cash it
receives under those contracts, together with the additional cash amount
described in the preceding paragraph, to holders of the DECS on or shortly
after that date. Therefore, holders of DECS may receive the cash and/or shares
to which they are entitled on two (but not more than two) separate dates up to
three months apart, and the dates and basis on which the cash or shares to
which they are entitled will not be the same for the two distributions.

   Rollover Offerings. Each seller has the option to deliver cash instead of
Common Stock on the Exchange Date (whether or not extended) by completing a
Rollover Offering to refinance the DECS.

   The term "Rollover Offering" means a reoffering or refinancing of the DECS
effected by [all sellers electing the Cash Delivery Option] not earlier than
  , 2002 by means of a completed public offering or offerings or another
similar offering (which may include one or more exchange offers), by or on
behalf of such seller[s]. If a seller elects to carry out a Rollover Offering,
the "Exchange Price" will be the Closing Price per share of Common Stock on the
Trading Day immediately preceding the date that the Rollover Offering is priced
(the "Pricing Date") or, if the Rollover Offering is priced after 4:00 p.m. New
York City time, on the Pricing Date, the Closing Price per share on the Pricing
Date.

   If a seller carries out a Rollover Offering that is consummated on or before
  , 2002, the cash payable by the seller will be delivered to the trust within
five Business Days after the Exchange Date (which may be extended and
accelerated as described above) instead of on the Exchange Date itself.
Accordingly, owners of the DECS may not receive a portion of the cash
deliverable in exchange for the DECS until the fifth Business Day after the
Exchange Date.

   The trust will notify the owners of the DECS (1) if any seller elects to
settle with cash, and whether it elects to do so in connection with a Rollover
Offering, not less than 30 days nor more than 90 days prior to the Exchange
Date, (2) if any seller elects to extend the Exchange Date, not less than 30
days nor more than 90 days prior to the Exchange Date as in effect when the
election is made, and (3) if any seller accelerates the Exchange Date in
connection with a Rollover Offering, not later than the Exchange Date as in
effect when the election is made.

   Dilution Adjustments. The Exchange Rate is subject to adjustment if Crown
Castle

  (1) pays a stock dividend or makes a distribution, in either case, with
      respect to Common Stock in shares of such stock,

  (2) subdivides or splits its outstanding shares of Common Stock into a
      greater number of shares,

  (3) combines its outstanding shares of Common Stock into a smaller number
      of shares,

  (4) issues by reclassification (other than a reclassification pursuant to
      clause (2), (3), (4) or (5) of the definition of Adjustment Event
      below) of its shares of Common Stock any other equity securities of
      Crown Castle, or

  (5) issues rights or warrants (other than rights to purchase Common Stock
      pursuant to a plan for the reinvestment of dividends or interest) to
      all holders of Common Stock entitling them to subscribe for or purchase
      shares of Common Stock at a price per share less than the Market Price
      (as defined below) of the Common Stock on the Business Day next
      following the record date for the determination of holders of Common
      Stock entitled to receive such rights or warrants.

   In the case of the events referred to in clauses (1), (2), (3) and (4)
above, the Exchange Rate will be adjusted by adjusting each of the Share
Components of the Exchange Rate in effect immediately prior to such event so
that the trust will be entitled under the prepaid forward contracts to receive
at the Exchange Date the number of shares of Common Stock (or, in the case of a
reclassification referred to in clause (4) above, the number of other equity
securities of Crown Castle issued pursuant thereto) which it would have owned
or been

                                       14
<PAGE>

entitled to receive immediately following such event had the Exchange Date
occurred immediately prior to such event or any record date with respect
thereto.

   In the case of the event referred to in clause (5) above, the Exchange Rate
will be adjusted by multiplying each of the Share Components of the Exchange
Rate in effect on the record date for the issuance of the rights or warrants
referred to in clause (5) above, by a fraction. The numerator of this fraction
is

  (A) the number of shares of Common Stock outstanding on the record date for
      the issuance of such rights or warrants, plus

  (B) the number of additional shares of Common Stock offered for
      subscription or purchase pursuant to such rights or warrants.

   The denominator of this fraction is

  (x) the number of shares of Common Stock outstanding on the record date for
      the issuance of such rights or warrants, plus

  (y) the number specified in clause (B) above multiplied by the quotient of

    (I) the exercise price of such rights or warrants divided by

    (II) the Market Price of the Common Stock on the Business Day next
         following the record date for the determination of holders of
         Common Stock entitled to receive such rights or warrants.

   To the extent that such rights or warrants expire prior to the Exchange Date
and shares of Common Stock are not delivered pursuant to such rights or
warrants prior to such expiration, the Exchange Rate will be readjusted to the
Exchange Rate which would then be in effect had such adjustments for the
issuance of such rights or warrants been made upon the basis of delivery of
only the number of shares of Common Stock actually delivered pursuant to such
rights or warrants. For purposes of this paragraph, dividends will be deemed to
be paid as of the record date for such dividend.

   "Market Price" means, as of any date of determination, the average Closing
Price per share of Common Stock on the 20 Trading Days immediately prior to
(but not including) the date of determination; provided, however, that if there
are not 20 Trading Days for the Common Stock occurring later than the 60th
calendar day immediately prior to, but not including, such date, the Market
Price will be determined as the market value per share of Common Stock as of
such date as determined by a nationally recognized investment banking firm that
the Administrator retains for such purpose.

   All adjustments to the Exchange Rate will be calculated to the nearest
1/10,000th of a share of Common Stock (or, if there is not a nearest 1/10,000th
of a share, to the next higher 1/10,000th of a share). No adjustment in the
Exchange Rate will be made unless such adjustment would require an increase or
decrease of at least one percent therein; provided, however, that any
adjustments which by reason of the foregoing are not required to be made will
be carried forward and taken into account in any subsequent adjustment. If an
adjustment is made to the Exchange Rate pursuant to clauses (1), (2), (3), (4)
or (5) above, an adjustment will also be made to the Exchange Price as such
term is used throughout the definition of Exchange Rate. The required
adjustment to the Exchange Price will be made at the Exchange Date by
multiplying the Exchange Price by the cumulative number or fraction determined
pursuant to the Exchange Rate adjustment procedure described above. In the case
of the reclassification of any shares of Common Stock into any equity
securities of Crown Castle other than the Common Stock, such equity securities
will be deemed shares of Common Stock for all purposes. Each such adjustment to
the Exchange Rate and the Exchange Price will be made successively.

   Adjustments Events. Each of the following events are called "Adjustment
Events":

  (1) any dividend or distribution by Crown Castle to all holders of Common
      Stock of evidences of its indebtedness or other assets (excluding any
      dividends or distributions referred to in clause (1) of the first
      paragraph under the caption "--Dilution Adjustments" above, any equity
      securities issued pursuant to a reclassification referred to in clause
      (4) of such paragraph and any Ordinary Cash

                                       15
<PAGE>

     Dividends (as defined below)) or any issuance by Crown Castle to all
     holders of Common Stock of rights or warrants to subscribe for or
     purchase any of its securities (other than rights or warrants referred
     to in clause (5) of the first paragraph under the caption "--Dilution
     Adjustments" above),

  (2) any consolidation or merger of Crown Castle with or into another entity
      (other than a merger or consolidation in which Crown Castle is the
      continuing corporation and in which the Common Stock outstanding
      immediately prior to the merger or consolidation is not exchanged for
      cash, securities or other property of Crown Castle or another
      corporation),

  (3) any sale, transfer, lease or conveyance to another corporation of the
      property of Crown Castle as an entirety or substantially as an
      entirety,

  (4) any statutory exchange of securities of Crown Castle with another
      corporation (other than in connection with a merger or acquisition),
      and

  (5) any liquidation, dissolution or winding up of Crown Castle.

   After the occurrence of any Adjustment Event, each seller will deliver at
the Exchange Date, in lieu of or (in the case of an Adjustment Event described
in clause (1) above) in addition to, shares of Common Stock as described
above, cash in an amount equal to

  (A) if the Exchange Price is greater than the Threshold Appreciation Price,
          multiplied by the Transaction Value (as defined below);

  (B) if the Exchange Price is less than or equal to the Threshold
      Appreciation Price but greater than the Initial Price, the product of
      (x) the Initial Price divided by the Exchange Price multiplied by (y)
      the Transaction Value; and

  (C) if the Exchange Price is less than or equal to the Initial Price, the
      Transaction Value;

provided, however, that if the consideration received by holders of Common
Stock in such Adjustment Event does not and may not at the option of such
holders include Reported Securities, then (except in the case of an Adjustment
Event solely of the type described in (1) above) (a) each seller's delivery
obligations under its prepaid forward contract will be accelerated and
promptly upon consummation of the Adjustment Event each seller will be
required to deliver cash in an amount equal to (x) if the Transaction Value is
greater than the Threshold Appreciation Price,     multiplied by the
Transaction Value, (y) if the Transaction Value is less than or equal to the
Threshold Appreciation Price but greater than Initial Price, the Initial
Price, and (z) if the Transaction Value is less than or equal to the Initial
Price, the Transaction Value; (b) the Custodian will liquidate the Treasury
Securities acquired by the trust at closing and then held by the trust; and
(c) the amount delivered by the sellers as described in (a) above and the
proceeds of such liquidation will be distributed to the owners of the DECS.

   Following an Adjustment Event, the Exchange Price, as such term is used in
the formula in the preceding paragraph and throughout the definition of
Exchange Rate, will be deemed to equal (A) if shares of Common Stock are
outstanding at the Exchange Date, the Exchange Price of the Common Stock, as
adjusted pursuant to the method described above under "--Dilution Adjustments"
otherwise zero, plus (B) the Transaction Value.

   Notwithstanding the foregoing, with respect to any securities received by
holders of Common Stock in an Adjustment Event that

  (1) are

    (a) listed on a United States national securities exchange,

    (b) reported on a United States national securities system subject to
        last sale reporting,

    (c) traded in the over-the-counter market and reported on the National
        Quotation Bureau or similar organization, or

                                      16
<PAGE>

    (d) for which bid and ask prices are available from at least three
        nationally recognized investment banking firms; and

  (2) are either (x) perpetual equity securities or (y) non-perpetual equity
      or debt securities with a stated maturity after the Exchange Date of
      the DECS

("Reported Securities"), each seller will, in lieu of delivering cash in
respect of such Reported Securities received in an Adjustment Event, deliver a
number of such Reported Securities with a value equal to all cash amounts that
would otherwise be deliverable in respect of Reported Securities received in
such Adjustment Event, as determined in accordance with clause (2) of the
definition of Transaction Value, unless such seller has made an election to
exercise the Cash Delivery Option or such Reported Securities have not yet been
delivered to the holders entitled thereto following such Adjustment Event or
any record date with respect thereto. If a seller delivers any Reported
Securities, upon distribution thereof by the trust to owners of DECS, each
owner of a DECS will be responsible for the payment of any and all brokerage
and other transaction costs upon the sale of such Reported Securities. If,
following any Adjustment Event, any Reported Security ceases to qualify as a
Reported Security, then (x) the seller will not deliver such Reported Security
but instead will deliver an equivalent amount of cash and (y) notwithstanding
clause (2) of the definition of Transaction Value, the Transaction Value of
such Reported Security will mean the fair market value of such Reported
Security on the date such security ceases to qualify as a Reported Security, as
determined by a nationally recognized investment banking firm that the
Administrator retains for this purpose.

   Because each DECS represents the right of the owner of the DECS to receive a
pro rata portion of the Common Stock or other assets delivered by the sellers
pursuant to the prepaid forward contracts, the amount of cash and/or the kind
and number of securities which the owners of DECS are entitled to receive after
an Adjustment Event will be adjusted following the date of such Adjustment
Event in the same manner and upon the occurrence of the same type of events as
described under the captions "--Dilution Adjustments" and "--Adjustment Events"
with respect to Common Stock and Crown Castle.

   For purposes of the foregoing, the term "Ordinary Cash Dividend" means, with
respect to any consecutive 365-day period, any dividend with respect to Common
Stock paid in cash to the extent that the amount of such dividend, together
with the total amount of all other dividends on the Common Stock paid in cash
during such 365-day period, does not exceed on a per share basis 10% of the
average of the Closing Prices of the Common Stock over such 365-day period.

   The term "Transaction Value" means

  (1) for any cash received in any Adjustment Event, the amount of cash
      received per share of Common Stock,

  (2) for any Reported Securities received in any Adjustment Event, an amount
      equal to (x) the average Closing Price per security of such Reported
      Securities on the 20 Trading Days immediately prior to (but not
      including) the Exchange Date multiplied by (y) the number of such
      Reported Securities (as adjusted pursuant to the methods described
      above under "--Dilution Adjustments" and "--Adjustment Events")
      received per share of Common Stock, and

  (3) for any property received in any Adjustment Event other than cash or
      such Reported Securities, an amount equal to the fair market value of
      the property received per share of Common Stock on the date such
      property is received, as determined by a nationally recognized
      investment banking firm that the Administrator retains for this
      purpose;

provided, however, that in the case of clause (2),

  (x) with respect to securities that are Reported Securities by virtue of
      only clause (d) of the definition of Reported Securities above,
      Transaction Value with respect to any such Reported Security means the

                                       17
<PAGE>

     average of the mid-point of the last bid and ask prices for such
     Reported Security as of the Exchange Date from each of at least three
     nationally recognized investment banking firms that the Administrator
     retains for such purpose multiplied by the number of such Reported
     Securities (as adjusted pursuant to the methods described above under
     "--Dilution Adjustments" and "--Adjustment Events") received per share
     of Common Stock, and

  (y) with respect to all other Reported Securities, if there are not 20
      Trading Days for any particular Reported Security occurring after the
      60th calendar day immediately prior to, but not including, the Exchange
      Date, Transaction Value with respect to such Reported Security means
      the market value per security of such Reported Security as of the
      Exchange Date as determined by a nationally recognized investment
      banking firm that the Administrator retains for such purpose multiplied
      by the number of such Reported Securities (as adjusted pursuant to the
      methods described above under "--Dilution Adjustments" and "--
      Adjustment Events") received per share of Common Stock.

For purposes of calculating the Transaction Value, any cash, Reported
Securities or other property receivable in an Adjustment Event will be deemed
to have been received immediately prior to the close of business on the record
date for such Adjustment Event or, if there is no record date for such
Adjustment Event, immediately prior to the close of business on the effective
date of such Adjustment Event.

   No adjustments will be made for certain other events, such as offerings of
Common Stock by Crown Castle for cash or in connection with acquisitions.
Likewise, no adjustments will be made for any sales of Common Stock by the
sellers.

   Each seller is required under its prepaid forward contract to notify the
trust promptly upon becoming aware that an event requiring an adjustment to
the Exchange Rate or which is an Adjustment Event is pending or has occurred.
The trust will, within ten Business Days following the occurrence of an event
that requires an adjustment to the Exchange Rate or the occurrence of an
Adjustment Event (or, in either case, if the trust is not aware of such
occurrence, as soon as practicable after becoming so aware), notify each owner
of DECS in writing of the occurrence of such event including a statement in
reasonable detail setting forth the method by which the adjustment to the
Exchange Rate or change in the consideration to be received by owners of DECS
following the Adjustment Event was determined and setting forth the revised
Exchange Rate or consideration, as the case may be. However, for any
adjustment to the Exchange Price, this notice will only disclose the factor by
which the Exchange Price is to be multiplied in order to determine which
clause of the Exchange Rate definition will apply at the Exchange Date.

   Collateral Requirements of the Forward Contracts; Acceleration. Each
seller's obligations under its prepaid forward contract will be secured by a
pledge of one share of Common Stock for each share of Common Stock subject to
the prepaid forward contract (subject to adjustment in accordance with the
dilution provisions of the prepaid forward contract), pursuant to a Collateral
Agreement among the seller, the trust and The Bank of New York, as collateral
agent (the "Collateral Agent"). In addition, the obligation of any seller to
pay an additional amount in connection with the extension or acceleration of
the Exchange Date will be secured by a pledge of U.S. Treasury securities (the
"Additional Government Securities").

   Unless they are in default in their obligations under their respective
Collateral Agreements, the sellers under two of the prepaid forward contracts
(representing 4,061,182 shares of Common Stock in the aggregate) will be
permitted to substitute for the pledged shares of Common Stock collateral
consisting of short-term, direct obligations of the U.S. Government. Any U.S.
Government obligations pledged as substitute collateral for shares of Common
Stock must have an aggregate market value at the time of substitution and at
daily mark-to-market valuations thereafter of not less than 150% (or, from and
after any Insufficiency Determination (as defined below) that is not cured by
the close of business on the next Business Day thereafter, as described below,
200%) of the product of the market price of the Common Stock at the time of
each valuation times the number of shares of Common Stock for which such
obligations are being substituted. Each of the Collateral Agreements provides
that, after an Adjustment Event, the relevant seller will pledge as
alternative collateral any Reported Securities, plus cash in an amount at
least equal to the Transaction Value of any consideration

                                      18
<PAGE>

other than Reported Securities, received by it in respect of the maximum number
of shares of Common Stock subject to its prepaid forward contract at the time
of the Adjustment Event. The number of Reported Securities required to be
pledged will be adjusted if any event requiring a dilution adjustment under the
prepaid forward contracts occurs. The two sellers referred to above will be
permitted to substitute U.S. Government obligations for Reported Securities or
cash pledged after any Adjustment Event. Any U.S. Government obligations so
substituted must have an aggregate market value at the time of substitution and
at daily mark-to-market valuations thereafter of:

  (A) in the case of obligations substituted for pledged Reported Securities,
      not less than 150% (or, from and after any Insufficiency Determination
      that is not cured by the close of business on the next Business Day
      thereafter, as described below, 200%) of the product of the market
      price per security of Reported Securities at the time of each valuation
      times the number of Reported Securities for which such obligations are
      being substituted; and

  (B) in the case of obligations substituted for pledged cash, not less than
      105% of the amount of cash for which such obligations are being
      substituted.

The Collateral Agent will promptly pay over to the relevant seller any
dividends, interest, principal or other payments received by the Collateral
Agent in respect of any collateral, including any substitute collateral, unless
the seller is in default of its obligations under its Collateral Agreement, or
unless the payment of such amount to the seller would cause the seller's
collateral to become insufficient under its Collateral Agreement.

   If the Collateral Agent determines (an "Insufficiency Determination") that
U.S. Government obligations pledged by a seller as substitute collateral fail
to meet the foregoing requirements at any valuation, or that a seller has
failed to pledge additional collateral required as a result of a dilution
adjustment increasing the maximum number of shares of Common Stock or Reported
Securities subject to its prepaid forward contract, and such failure is not
cured by the close of business on the next Business Day after such
determination, then, unless a Collateral Event of Default (as defined below)
under the relevant Collateral Agreement has occurred and is continuing, the
Collateral Agent will commence (1) sales of the collateral consisting of U.S.
Government obligations and (2) purchases, using the proceeds of such sales, of
shares of Common Stock or Reported Securities in an amount sufficient to cause
the collateral to meet the requirements under the relevant Collateral
Agreement. The Collateral Agent will discontinue such sales and purchases if at
any time a Collateral Event of Default under the relevant Collateral Agreement
has occurred and is continuing.

   The occurrence of a Collateral Event of Default (as defined below) under any
seller's Collateral Agreement, or the bankruptcy or insolvency of a seller,
will cause an automatic acceleration of that seller's obligations under its
prepaid forward contract. A "Collateral Event of Default" under a Collateral
Agreement means, at any time,

  (A) if no U.S. Government obligations are pledged as substitute collateral
      at such time, failure of the collateral to consist of at least the
      maximum number of shares of Common Stock subject to the relevant
      seller's prepaid forward contract at such time (or, if an Adjustment
      Event has occurred at or prior to such time, failure of the collateral
      to include the amount of cash and the maximum number of any Reported
      Securities required to be pledged by that seller as described above);

  (B) if any U.S. Government obligations are pledged as substitute collateral
      for shares of Common Stock (or Reported Securities) under that
      Collateral Agreement at such time, failure of such U.S. Government
      obligations to have a market value at such time of at least 105% of the
      market price of the Common Stock (or the then-current market price per
      security of Reported Securities, as the case may be) times the
      difference between

    (x) the maximum number of shares of Common Stock (or Reported
        Securities) subject to the relevant seller's prepaid forward
        contract at such time, and

    (y) the number of shares of Common Stock (or Reported Securities)
        pledged as collateral by that seller at such time; and

                                       19
<PAGE>

  (C) if any U.S. Government obligations are pledged as substitute collateral
      for any cash under that Collateral Agreement at such time, failure of
      such U.S. Government obligations to have a market value at such time of
      at least 105% of such cash, if such failure is not cured within one
      Business Day after notice thereof is delivered to the relevant seller.

   Except as described below, upon acceleration of any seller's prepaid forward
contract, the Collateral Agent will to the extent permitted by law distribute
to the trust for distribution pro rata to investors the maximum number of
shares of Common Stock subject to such prepaid forward contract, in the form of
the shares of Common Stock then pledged by that seller, or cash generated from
the liquidation of U.S. Government obligations then pledged by that seller, or
a combination thereof (or, after an Adjustment Event, in the form of Reported
Securities then pledged, cash then pledged, cash generated from the liquidation
of U.S. Government obligations then pledged, or a combination thereof). In
addition, if by the Exchange Date any substitute collateral has not been
replaced by shares of Common Stock (or, after an Adjustment Event, cash or
Reported Securities) sufficient to meet the obligations under a seller's
prepaid forward contract, the Collateral Agent will distribute to the trust for
distribution pro rata to investors the market value of the shares of Common
Stock required to be delivered thereunder, in the form of any shares of Common
Stock then pledged by that seller plus cash generated from the liquidation of
U.S. Government obligations then pledged by that seller (or, after an
Adjustment Event, the market value of the alternative consideration required to
be delivered thereunder, in the form of any Reported Securities then pledged,
plus any cash then pledged, plus cash generated from the liquidation of U.S.
Government obligations then pledged).

   If upon acceleration of a seller's prepaid forward contract, that seller is
subject to a bankruptcy or similar proceeding, the Collateral Agent will to the
extent permitted by law distribute to the trust for distribution pro rata to
the investors a number of shares of Common Stock, in the form of the shares of
Common Stock then pledged by that seller, or cash generated from the
liquidation of U.S. Government obligations then pledged by that seller, or a
combination thereof (or, after an Adjustment Event, in the form of Reported
Securities then pledged, cash then pledged, cash generated from the liquidation
of U.S. Government obligations then pledged, or a combination thereof), with an
aggregate value equal to the "Acceleration Value." The Administrator will
determine the Acceleration Value on the basis of quotations from independent
dealers. Each quotation will be for an amount that would be paid to the
relevant dealer in consideration of an agreement that would have the effect of
preserving the trust's rights to receive the number of shares of Common Stock
(or, after an Adjustment Event, Reported Securities, cash or a combination
thereof) subject to the relevant seller's prepaid forward contract on the
Exchange Date. The Administrator will request quotations from four nationally
recognized independent dealers on or as soon as reasonably practicable
following the date of acceleration. If four quotations are provided, the
Acceleration Value will be the arithmetic mean of the two quotations remaining
after disregarding the highest and lowest quotations. If two or three
quotations are provided, the Acceleration Value will be the arithmetic mean of
such quotations. If one quotation is provided, the Acceleration Value will be
such quotation. If no quotations are provided, the Acceleration Value will be
the aggregate value of the number of shares of Common Stock (or, after an
Adjustment Event, Reported Securities, cash or a combination thereof) that
would be required to be delivered under the relevant seller's prepaid forward
contract on the date of acceleration if the Exchange Date were redefined to be
the date of acceleration.

   The trust's recourse to the sellers under two of the prepaid forward
contracts representing 938,818 shares of Common Stock in the aggregate (plus up
to an additional 645,000 shares if the underwriters' over-allotment option is
exercised in full) will be limited to the Common Stock (or, after an Adjustment
Event, cash or Reported Securities) pledged thereunder. Such sellers will not
be permitted to substitute U.S. Government obligations for shares of Common
Stock, Reported Securities or cash pledged under their Collateral Agreements.

   Description of the Sellers. Specific information on the holdings of the
sellers, as required by the Securities Act of 1933, as amended (the "Securities
Act"), is included in the prospectus and prospectus supplement of Crown Castle
attached hereto.

                                       20
<PAGE>

The Treasury Securities

   The trust will purchase and hold a series of zero-coupon ("stripped") U.S.
Treasury securities with such face amounts and maturities as will provide
investors with a quarterly distribution of $    per DECS on each Distribution
Date during the term of the trust. The trust may invest up to 35% of its total
assets in these Treasury Securities. If any prepaid forward contract is
accelerated, the Administrator will liquidate a proportionate amount of the
Treasury Securities then held in the trust and will distribute the proceeds
thereof pro rata to investors, together with proceeds from the acceleration of
the prepaid forward contract. See "--The Forward Contracts--Collateral
Requirements of the Forward Contract; Acceleration" above and "--Trust
Termination" below.

   If a seller extends the Exchange Date, it will be required to pledge
Additional Government Securities to the trust as collateral securing its
obligation to pay the additional amount described above under "--The Forward
Contracts--Extension and Acceleration of the Exchange Date at the Option of the
Sellers."

Temporary Investments

   For cash management purposes, the trust may invest the proceeds of the
Treasury Securities held by the trust and any other cash held by the trust in
short-term obligations of the U.S. Government maturing no later than the
Business Day preceding the next distribution date.

Trust Termination

   The trust will terminate automatically on or shortly after the latest
Exchange Date or following the distribution of all trust assets to investors,
if earlier.

   If all of the prepaid forward contracts are accelerated, the Administrator
will liquidate any Treasury Securities then held by the trust and will
distribute the proceeds thereof pro rata to the investors, together with all
shares of Common Stock subject to the prepaid forward contracts that are
pledged by the sellers, or cash generated from the liquidation of U.S.
Government obligations then pledged by the sellers, or a combination thereof
(or, after an Adjustment Event, in the form of Reported Securities then
pledged, cash then pledged, cash generated from the liquidation of U.S.
Government obligations then pledged, or a combination thereof) or in certain
cases, the Acceleration Value of the prepaid forward contracts. After this
distribution, the term of the trust will expire. See "--The Forward Contracts--
Collateral Requirements of the Forward Contracts; Acceleration" above.

Delivery of Common Stock and Reported Securities; No Fractional Shares of
Common Stock or Reported Securities

   Common Stock and Reported Securities delivered under the prepaid forward
contracts at the Exchange Date are expected to be distributed by the trust to
the investors pro rata shortly after the Exchange Date, except that no
fractional shares of Common Stock or Reported Securities will be distributed.
If more than one DECS is surrendered at one time by the same investor, the
number of full shares of Common Stock or Reported Securities to be delivered
upon termination of the trust, in whole or in part, as the case may be, will be
computed on the basis of the total number of DECS so surrendered at the
Exchange Date. Instead of delivering any fractional share or security, the
trust will sell a number of shares or securities equal to the total of all
fractional shares or securities that would otherwise be delivered to investors
of all DECS, and each such investor will be entitled to receive an amount in
cash equal to the pro rata portion of the proceeds of such sale (which may be
at a price lower than the Exchange Price).

                                       21
<PAGE>

                            INVESTMENT RESTRICTIONS

   The trust has adopted a fundamental policy that the trust may not purchase
any securities or instruments other than the Treasury Securities, the prepaid
forward contracts and the Common Stock or other assets received pursuant to the
prepaid forward contracts and, for cash management purposes, short-term
obligations of the U.S. Government; issue any securities or instruments except
for the DECS; make short sales or purchase securities on margin; write put or
call options; borrow money; underwrite securities; purchase or sell real
estate, commodities or commodities contracts; or make loans. The trust has also
adopted a fundamental policy that the trust may not dispose of the prepaid
forward contracts during the term of the trust and (except for a partial
liquidation of Treasury Securities following acceleration of any prepaid
forward contract as described above under "Investment Objectives and Policies--
The Treasury Securities") the trust may not dispose of the Treasury Securities
prior to the earlier of their respective maturities and the termination of the
trust.

                             Risk Factors for DECS

   The DECS may trade at widely different prices before maturity depending upon
factors such as changes in the market price of the Crown Castle common stock
and other events that the trust cannot predict and are beyond the trust's
control. The text describes this in more detail below.

Internal Management; No Portfolio Management

   The internal operations of the trust will be managed by its trustees; the
trust will not have any separate investment advisor. The trust has adopted a
fundamental policy that the trust may not dispose of the prepaid forward
contracts during the term of the trust and the trust may not dispose of the
Treasury Securities held by the trust prior to the earlier of their maturities
and the termination of the trust, except for a partial liquidation of Treasury
Securities following acceleration of a prepaid forward contract. As a result,
the trust will continue to hold the prepaid forward contracts even if there is
a significant decline in the market price of the Crown Castle common stock or
adverse changes in the financial condition of Crown Castle (or, after an
Adjustment Event, comparable developments affecting any Reported Securities or
the issuer of such securities). The trust will not be managed like a typical
closed-end investment company.

Comparison to Other Securities; Relationship to Crown Castle Shares

   The DECS are different from ordinary securities because the value of the
Crown Castle common stock, cash or other securities you will receive on
termination of the trust may be more or less than the initial price of the
DECS. If the value of a share of Crown Castle common stock shortly before the
exchange date is less than the price you paid for each of your DECS, you will
suffer a loss on your investment in the DECS. If Crown Castle is insolvent or
bankrupt when the DECS mature, you might lose your entire investment. You take
all the risk of a fall in the value of Crown Castle common stock before the
exchange date.

   In addition, you have less opportunity to make money from an increase in the
price of Crown Castle common stock by investing in the DECS than by investing
directly in Crown Castle common stock. The value of what you receive when the
trust is terminated will be greater than the initial price of the DECS only if
the value of Crown Castle common stock exceeds $    per share. This is an
increase of about     % over the price of Crown Castle common stock when the
DECS were first offered for sale. In addition, you will receive only about
    % of any increase in the value of a Crown Castle common stock above $
per share.

   In return, you will receive annual distributions on the DECS at a rate of
    %, which is more than the historical annual dividend on a Crown Castle
common stock, which currently pay no dividends. However, Crown Castle could pay
dividends in the future that are higher than the distributions that you receive
from the trust.

   The trust cannot predict whether the price of a Crown Castle common stock
will rise or fall. However, the following factors may affect the trading price
of Crown Castle common stock:

  .  whether Crown Castle makes a profit and what its future prospects are;

                                       22
<PAGE>

  .  trading in the capital markets generally;

  .  trading on Nasdaq, where the Crown Castle common stock is traded;

  .  the health of the tower and transmission networks industry; and

  .  whether Crown Castle issues securities like the DECS, or Crown Castle or
     another person in the market transfers a large amount of Crown Castle
     common stock.

   As of the date of this prospectus, the sellers owned a total of    shares of
Crown Castle common stock, of which the sellers may deliver up to    shares of
Crown Castle common stock (    shares if the underwriters' over-allotment
option is exercised in full) to the trust at the exchange date.

   Please refer to the attached prospectus and prospectus supplement for
information about Crown Castle and the Crown Castle common stock.

Impact of the DECS on the Market for the Crown Castle Shares

   The trust cannot predict accurately how or whether investors will resell the
DECS and how easy it will be to resell them. Any market that develops for the
DECS is likely to influence and be influenced by the market for Crown Castle
common stock. For example, investors' anticipation that the sellers may deliver
Crown Castle common stock that represents approximately   % of the currently
outstanding Crown Castle common stock when the DECS mature could cause the
price of Crown Castle common stock to be unstable or fall. The following
factors could also affect the price of Crown Castle common stock:

  .  sales of Crown Castle common stock by investors who prefer to invest in
     Crown Castle by investing in the DECS;

  .  hedging of investments in the DECS by selling Crown Castle common stock
     (called "selling short"); and

  .  arbitrage trading activity between the DECS and Crown Castle common
     stock.

Dilution of Crown Castle Shares; Lack of Stockholder Rights

   The terms of the DECS include some protections so you will receive
equivalent value when the DECS mature even if Crown Castle splits or combines
its shares, pays stock dividends or does other similar things that change the
amount of Crown Castle common stock currently outstanding. However, these terms
will not protect you against all events. For example, the amount you receive
when the DECS mature may not change if Crown Castle offers shares for cash or
in an acquisition, even if the price of Crown Castle common stock falls and
this causes the price of the DECS to fall. The trust has no control over
whether Crown Castle will offer shares or do something similar in the future or
the amount of any offering.

   In addition, unless and until a seller decides to deliver Crown Castle
common stock to the trust when the DECS mature and until the trust distributes
the Crown Castle common stock to you, you will have no dividend rights or other
similar rights associated with Crown Castle common stock.

Crown Castle not Responsible for the DECS

   Crown Castle has no obligation to make any payments on the DECS. Crown
Castle also does not have to take the trust's needs or your needs into
consideration for any reason. Crown Castle will not receive any money from the
sale of the DECS and did not decide to issue the DECS. Crown Castle did not
determine when the trust will issue the DECS, how much the trust will sell them
for or how many the trust will sell. Crown Castle is not involved in managing
or trading the DECS or determining or calculating the amount you will receive
when the DECS mature.

                                       23
<PAGE>

DECS May be Difficult to Resell

   The DECS are new and innovative securities, and there is currently no market
in which to resell them. The underwriters currently intend, but are not
obligated, to buy and sell the DECS. A resale market might not develop or, if
it does, might not give you the opportunity to resell your DECS and may not
continue until the DECS mature.

   The trust has applied to have the DECS approved for listing on the Nasdaq
National Market. Nonetheless, the Nasdaq might not approve the application or
if approved, could revoke the listing after approval or stop trading of the
DECS at any time. If Nasdaq will no longer quote the DECS or stops trading
them, the trust will ask another national securities exchange to list the DECS
or another trading market to quote them. If the DECS are no longer listed or
traded on any securities exchange or trading market, or if a securities
exchange or trading market stops trading of the DECS, you may have difficulty
getting price information and it may be more difficult to resell the DECS.

Net Asset Value of the Trust

   The trust is a newly organized closed-end investment company with no
previous operating history. Shares of closed-end investment companies
frequently trade at a discount from their net asset value, which is a risk
separate and distinct from the risk that the trust's net asset value will
decrease. The trust cannot predict whether the DECS will trade at, below or
above their net asset value. For investors who wish to sell the DECS in a
relatively short period of time after the DECS offering, the risk of the DECS
trading at a discount is more pronounced because the gain or loss that such
investors realize on their investment is likely to be depend more on whether
the DECS are trading at a discount or premium than upon the value of the
trust's assets. The trust will not redeem any DECS prior to the exchange date
of the Crown Castle common stock or the earlier termination of the trust.

Non-Diversified Status

   The trust is considered non-diversified under the Investment Company Act of
1940, which means that the trust is not limited in the proportion of its assets
that may be invested in one security. Because the trust will only own the
Treasury Securities, the prepaid forward contracts or other assets subject to
the prepaid forward contracts, the DECS may be a riskier investment than would
be the case for an investment company with more diversified investments.

Tax Treatment of DECS Uncertain

   No statutory, judicial or administrative authority directly addresses the
characterization of the DECS or instruments similar to the DECS for U.S.
federal income tax purposes. As a result, significant aspects of the U.S.
federal income tax consequences of an investment in the DECS are not certain.
There is no ruling from the Internal Revenue Service with respect to the DECS
and the Internal Revenue Service might not agree with the conclusions expressed
under the section "Certain United States Federal Income Tax Considerations" in
this prospectus.

Risk Factors for Crown Castle

   You should carefully consider the information in the attached prospectus and
prospectus supplement of Crown Castle, including the risk factors for Crown
Castle on pages    to     of the attached prospectus supplement.

Risk Relating to Bankruptcy of the Sellers

   It is possible that one or more of the sellers may be the subject of
proceedings under the U.S. Bankruptcy Code. The trust believes that each
prepaid forward contract constitutes a "securities contract" for purposes of

                                       24
<PAGE>

the U.S. Bankruptcy Code, liquidation of which would not be subject to the
automatic stay provisions of the U.S. Bankruptcy Code in the event of the
bankruptcy of the relevant seller. It is, however, possible that a prepaid
forward contract could be determined not to qualify as a "securities contract"
for this purpose.

   Proceedings under the U.S. Bankruptcy Code in respect of any seller may thus
cause a delay in settlement of that seller's prepaid forward contract, or
otherwise subject the prepaid forward contract to such proceedings. In turn,
this could adversely affect the timing of settlement and could impair the
trust's ability to distribute the Crown Castle common stock or other assets
subject to that prepaid forward contract and the related Collateral Agreement
to you on a timely basis and, as a result, could adversely affect the amount
received by you in respect of the DECS and/or the timing of such receipt.

                                       25
<PAGE>

                                NET ASSET VALUE

   The Administrator will calculate the net asset value of the portfolio at
least quarterly by dividing the value of the net assets of the trust (the value
of its assets less its liabilities) by the total number of DECS outstanding.
The trust's net asset value will be published semi-annually as part of the
trust's semi-annual report to investors and at such other times as the trust is
may determine. The Treasury Securities held by the trust will be valued at the
mean between the last current bid and asked prices or, if quotations are not
available, as determined in good faith by the trustees. Short-term investments
having a maturity of 60 days or less will be valued at cost with accrued
interest or discount earned included in interest to be received. Each of the
prepaid forward contracts will be valued at the mean of the bid prices the
trust receives from at least three independent broker-dealer firms unaffiliated
with the trust who are in the business of making bids on financial instruments
similar to the prepaid forward contracts and with terms comparable thereto. If
the trust (acting through the Administrator) is unable to obtain valuations
from three independent broker-dealer firms, as required by the preceding
sentence, on a timely basis or without unreasonable effort or expense, the
prepaid forward contracts will be valued at the median of bid prices received
from two such broker-dealer firms. If the trust (acting through the
Administrator) is unable to obtain a valuation for the prepaid forward
contracts that it believes to be reasonable through the above method, the value
of the prepaid forward contracts will be established at a level deemed to be
fair and reflective of the market value for the prepaid forward contracts based
on all appropriate factors relevant to the value of the prepaid forward
contracts as set forth in pricing guidelines adopted by the trustees.

                                       26
<PAGE>

                            DESCRIPTION OF THE DECS

   Each DECS represents an equal proportional interest in the trust. Upon
liquidation of the trust, investors are entitled to share pro rata in the net
assets of the trust available for distribution. DECS have no preemptive,
redemption or conversion rights. The DECS, when issued and outstanding, will be
fully paid and non-assessable. The only securities that the trust is authorized
to issue are the DECS offered hereby and those sold to the initial investor
referred to below. See "Underwriting."

   Owners of DECS are entitled to one vote for each DECS held on all matters to
be voted on by investors and are not able to cumulate their votes in the
election of Trustees. The trustees of the trust have been selected initially by
Salomon Smith Barney as the initial investor in the trust. The trust intends to
hold annual meetings as required by the rules of Nasdaq.

   The trustees may call special meetings of investors for action by investor
vote as may be required by either the Investment Company Act or the Declaration
of Trust. Investors have the right, upon the declaration in writing or vote of
more than two-thirds of the outstanding DECS, to remove a Trustee. The Trustees
will call a meeting of investors to vote on the removal of a Trustee upon the
written request of the record owners of 10% of the DECS or to vote on other
matters upon the written request of the record owners of 51% of the DECS
(unless substantially the same matter was voted on during the preceding 12
months). The Trustees shall establish, and notify the investors in writing of,
the record date for each such meeting, which shall be not less than 10 nor more
than 50 days before the meeting date. Owners at the close of business on the
record date will be entitled to vote at the meeting. The trust will also assist
in communications with other owners as required by the Investment Company Act.

Book-Entry System

   The DECS will be issued in the form of one or more global securities (the
"Global Security") deposited with The Depository Trust Company (the
"Depositary") and registered in the name of a nominee of the Depositary.

   The Depositary has advised the trust and the underwriters as follows: The
Depositary is a limited-purpose trust company organized under the laws of the
State of New York, a member of the Federal Reserve System, a "clearing
corporation" within the meaning of the New York Uniform Commercial Code and a
"clearing agency" registered pursuant to Section 17A of the Securities Exchange
Act of 1934, as amended. The Depositary was created to hold securities of
persons who have accounts with the Depositary ("participants") and to
facilitate the clearance and settlement of securities transactions among its
participants in such securities through electronic book-entry changes in
accounts of the participants, thereby eliminating the need for physical
movement of certificates. Such participants include securities brokers and
dealers, banks, trust companies and clearing corporations. Indirect access to
the Depositary's book-entry system is also available to others, such as banks,
brokers, dealers and trust companies that clear through or maintain a custodial
relationship with a participant, either directly or indirectly.

   Upon the issuance of a Global Security, the Depositary or its nominee will
credit the respective DECS represented by such Global Security to the accounts
of participants. The accounts to be credited will be designated by the
underwriters. Ownership of beneficial interests in such Global Security will be
limited to participants or persons that may hold interests through
participants. Ownership of beneficial interests by participants in such Global
Security will be shown on, and the transfer of those ownership interests will
be effected only through, records maintained by the Depositary or its nominee
for such Global Security. Ownership of beneficial interests in such Global
Security by persons that hold through participants will be shown on, and the
transfer of that ownership interest within such participant will be effected
only through, records maintained by such participant. The laws of some
jurisdictions require that certain purchasers of securities take physical
delivery of such securities in definitive form. Such limits and such laws may
impair the ability to transfer beneficial interests in a Global Security.

                                       27
<PAGE>

   So long as the Depositary for a Global Security, or its nominee, is the
registered owner of such Global Security, such Depositary or such nominee, as
the case may be, will be considered the sole owner or holder of the DECS.
Except as set forth below, owners of beneficial interests in such Global
Security will not be entitled to have the DECS registered in their names and
will not receive or be entitled to receive physical delivery of the DECS in
definitive form and will not be considered the owners or holders thereof.

   Shares of Common Stock or other assets deliverable in respect of, and any
quarterly distributions on, DECS registered in the name of or held by the
Depositary or its nominee will be made to the Depositary or its nominee, as the
case may be, as the registered owner or the holder of the Global Security. None
of the trust, any Trustee, the Paying Agent, the Administrator or the Custodian
for the DECS will have any responsibility or liability for any aspect of the
records relating to, or payments made on account of, beneficial ownership
interests in a Global Security or for maintaining, supervising or reviewing any
records relating to such beneficial ownership interests.

   The trust expects that the Depositary, upon receipt of any payment in
respect of a permanent Global Security, will credit immediately participants'
accounts with payments in amounts proportionate to their respective beneficial
interests in the principal amount of such Global Security as shown on the
records of the Depositary. The trust also expects that payments by participants
to owners of beneficial interests in such Global Security held through such
participants will be governed by standing instructions and customary practices,
as is now the case with securities held for the accounts of customers in bearer
form or registered in "street name," and will be the responsibility of such
participants.

   A Global Security may not be transferred except as a whole by the Depositary
to a nominee or a successor of the Depositary. If the Depositary is at any time
unwilling or unable to continue as depositary and a successor depositary is not
appointed by the trust within 90 days, the trust will issue DECS in definitive
registered form in exchange for the Global Security representing such DECS. In
that event, an owner of a beneficial interest in a Global Security will be
entitled to physical delivery in definitive form of DECS represented by such
Global Security equal in number to that represented by such beneficial interest
and to have such DECS registered in its name.

                   MANAGEMENT AND ADMINISTRATION OF THE TRUST

Trustees

   The internal operations of the trust will be managed by three Trustees, none
of whom is an "interested person" of the trust as defined in the Investment
Company Act; the trust will not have an investment adviser. Under the
provisions of the Internal Revenue Code of 1986, as amended (the "Code"),
applicable to grantor trusts, the Trustees will not have the power to vary the
investments held by the trust.

   The names of the persons who will be elected by Salomon Smith Barney, the
sponsor/initial investor of the trust, to serve as the Trustees are set forth
below. The positions and the principal occupations of the individual Trustees
during the past five years are also set forth below.

   Salomon Smith Barney will pay each Trustee who is not a director, officer or
employee of either the underwriters or the Administrator, or of any affiliate
thereof, in respect of his annual fee and anticipated out-of-pocket expenses, a
one-time, up-front fee of $10,800 in the aggregate. The trust's Managing
Trustee will also receive an additional up-front fee of $3,600 in the aggregate
for serving in that capacity. Except as otherwise noted, the sellers will
reimburse Salomon Smith Barney for any of these payments as part of the
expenses of the trust. The Trustees will not receive, either directly or
indirectly, any compensation, including any pension or retirement benefits,
from the trust. None of the Trustees receives any compensation for serving as a
trustee or director of any other affiliated investment company.

Administrator

   The day-to-day affairs of the trust will be managed by The Bank of New York,
as Trust Administrator pursuant to an administration agreement. Under the
administration agreement, the Trustees have delegated most of their operational
duties to the Administrator, including without limitation, their duties to:

  (1) receive invoices for and pay, or cause to be paid, all expenses
      incurred by the trust;

  (2) with the approval of the Trustees, engage legal and other professional
      advisors (other than the independent public accountants for the trust);

  (3) instruct the Paying Agent to pay distributions on DECS as described
      herein;

  (4) prepare and mail, file or publish all notices, proxies, reports, tax
      returns and other communications and documents, and keep all books and
      records, for the trust;

                                       29
<PAGE>

  (5) at the direction of the Trustees, institute and prosecute legal and
      other appropriate proceedings to enforce the rights and remedies of the
      trust; and

  (6) make all necessary arrangements with respect to meetings of Trustees
      and any meetings of holders of DECS.

The Administrator will not, however, select the independent public accountants
for the trust or sell or otherwise dispose of the trust's assets (except in
connection with an acceleration of a prepaid forward contract, or the
settlement of the prepaid forward contracts at the Exchange Date, and upon
termination of the trust).

   Either the trust or the Administrator may terminate the Administration
Agreement upon 60 days' prior written notice, except that no termination shall
become effective until a successor Administrator has been chosen and has
accepted the duties of the Administrator.

   Except for its roles as Administrator, Custodian, paying agent, registrar
and transfer agent of the trust, and except for its role as Collateral Agent
under the Collateral Agreements, The Bank of New York has no other affiliation
with, and is not engaged in any other transactions with, the trust.

   The address of the Administrator is 101 Barclay Street, New York, New York
10286.

Custodian

   The trust's custodian (the "Custodian") is The Bank of New York pursuant to
a custodian agreement. In the event of any termination of the custodian
agreement by the trust or the resignation of the Custodian, the trust must
engage a new Custodian to carry out the duties of the Custodian as set forth in
the custodian agreement. Pursuant to the custodian agreement, the Custodian
will invest all net cash received by the trust in short-term U.S. Government
securities maturing on or shortly before the next quarterly distribution date.
The Custodian will also act as Collateral Agent under the Collateral Agreements
and will hold a perfected security interest in the Common Stock and U.S.
Government obligations or other assets consistent with the terms of the prepaid
forward contracts.

Paying Agent

   The transfer agent, registrar and paying agent (the "Paying Agent") for the
DECS is The Bank of New York pursuant to a paying agent agreement. In the event
of any termination of the paying agent agreement by the trust or the
resignation of the Paying Agent, the trust will use its best efforts to engage
a new Paying Agent to carry out the duties of the Paying Agent.

Indemnification

   The trust will indemnify each Trustee, the Administrator, the Custodian and
the Paying Agent with respect to any claim, liability, loss or expense
(including the costs and expenses of the defense against any claim or
liability) which it may incur in acting as Trustee, Administrator, Custodian or
Paying Agent, as the case may be, except in the case of willful misfeasance,
bad faith, gross negligence or reckless disregard of their respective duties or
where applicable law prohibits such indemnification. Salomon Smith Barney has
agreed to reimburse the trust for any amounts it may be required to pay as
indemnification to any Trustee, the Administrator, the Custodian or the Paying
Agent. Except as otherwise noted, the sellers in turn will reimburse Salomon
Smith Barney for all such reimbursements paid by it as part of the expenses of
the trust.

Distributions

   The trust intends to distribute to investors on a quarterly basis the
proceeds of the Treasury Securities held by the trust. The first distribution,
reflecting the trust's operations from the date of this offering, will be made
on   , 1999 to owners of record as of    , 1999. Thereafter, the trust will
make distributions on   ,

                                       30
<PAGE>

  ,    and    or, if any such date is not a Business Day, on the next
succeeding Business Day, of each year to owners of record as of each    ,   ,
   and    , respectively. A portion of each such distribution should be treated
as a tax-free return of the investor's investment. See "Investment Objective
and Policies--Trust Assets" and "Certain United States Federal Income Tax
Considerations." If any prepaid forward contract is accelerated as described in
"Investment Objectives and Policies--The Forward Contracts--Collateral
Requirements of the Contract; Acceleration," each investor will receive its pro
rata share of the proceeds from the acceleration of that prepaid forward
contract and from the liquidation of a proportionate share of the Treasury
Securities then held in the trust. Upon termination of the trust as described
in "Investment Objectives and Policies--Trust Termination," each investor will
receive its pro rata share of any remaining net assets of the trust.

   The trust does not permit the reinvestment of distributions.

Estimated Expenses

   At the closing of this offering, Salomon Smith Barney will pay to each of
the Administrator, the Custodian and the Paying Agent, and to each Trustee, a
one-time, up-front amount in respect of such party's ongoing fees and, in the
case of the Administrator, anticipated expenses of the trust over the term of
the trust. The anticipated trust expenses to be borne by the Administrator
include, among other things, expenses for legal and independent accountants'
services, costs of printing proxies, DECS certificates and investor reports,
expenses of the trustees, fidelity bond coverage, stock exchange listing fees
and expenses of qualifying the DECS for sale in the various states. The one-
time, up-front payments described above total $  . Salomon Smith Barney also
will pay estimated organization costs of the trust in the amount of $   and
estimated costs of the trust in connection with the initial registration and
public offering of the DECS in the amount of $   at the closing of the
offering.

   The amount payable to the Administrator in respect of ongoing expenses of
the trust was determined based on estimates made in good faith on the basis of
information currently available to the trust, including estimates furnished by
the trust's agents. Actual operating expenses of the trust may be substantially
more than this amount. Any additional expenses will be paid by Salomon Smith
Barney or, in the event of its failure to pay such amounts, the sellers, or, in
the event of the failure of either of Salomon Smith Barney, or the sellers to
pay such amounts, the trust. The sellers will reimburse Salomon Smith Barney
for certain expenses of the trust paid by it.

            CERTAIN UNITED STATES FEDERAL INCOME TAX CONSIDERATIONS

   The following is a summary of the principal U.S. federal income tax
consequences that may be relevant to an owner of a DECS that is a "U.S.
Holder." A DECS owner will be treated as a U.S. Holder for U.S. federal income
tax purposes if the owner is:

  .  an individual who is a citizen or resident of the United States,

  .  a U.S. domestic corporation, or

  .  any other person that is subject to U.S. federal income taxation on a
     net income basis in respect of its investment in DECS.

   This summary is based on the U.S. federal income tax laws, regulations,
rulings and decisions now in effect, all of which are subject to change,
possibly on a retroactive basis. Except to the extent discussed below under
"Non-U.S. Holders," this summary applies only to U.S. Holders that will hold
DECS as capital assets, and only if the investor purchased the DECS in their
initial offering. This summary does not address all aspects of U.S. federal
income taxation that may be relevant to an investor in light of the investor's
individual investment circumstances, and does not address tax considerations
applicable to investors that may be subject to special tax rules, such as
dealers in securities or foreign currencies, traders in securities or
commodities electing to mark to market, financial institutions, insurance
companies, tax-exempt organizations, persons that will hold DECS as a position
in a "straddle" for tax purposes or as a part of a "synthetic security" or a
"conversion transaction" or other integrated investment comprised of a DECS and
one or more other investments, or persons that have a functional currency other
than the U.S. dollar.

   This summary does not include any description of the tax laws of any state
or local governments or of any foreign government that may be applicable to the
DECS or to the owners thereof. It also does not discuss the tax consequences of
the ownership of the Common Stock or Reported Securities. Investors should
consult their own tax advisors in determining the tax consequences to them of
holding DECS, including the application to their particular situation of the
U.S. federal income tax considerations discussed below, as well as the
application of state, local or other tax laws.

   There are no regulations, published rulings or judicial decisions addressing
the characterization for federal income tax purposes of securities with terms
substantially the same as the DECS. Pursuant to the terms of the Declaration of
Trust, the trust and every holder of the DECS agree to treat a DECS for U.S.
federal income tax purposes as a beneficial interest in a trust that holds
zero-coupon U.S. Treasury securities and the prepaid forward contracts. The
trust intends to report holders' income to the Internal Revenue Service in
accordance with this treatment. In addition, pursuant to the terms of the
prepaid forward contracts and the Declaration of Trust, the sellers, the trust
and every holder of a DECS will be obligated (in the absence of an
administrative determination or judicial ruling to the contrary) to
characterize the prepaid forward contracts for all tax purposes as forward
purchase contracts to purchase Common Stock at the Exchange Date (including as
a result of acceleration or otherwise), under the terms of which contract:

  (a) at the time of issuance of the DECS the holder is required to deposit
      irrevocably with the sellers a fixed amount of cash equal to the
      purchase price of the DECS, less the purchase price of the Treasury
      Securities, to assure the fulfillment of the obligation described in
      clause (b) below, and

  (b)  at Maturity such cash deposit unconditionally and irrevocably will be
       applied by the sellers in full satisfaction of the holder's payment
       obligation under the forward contracts, and the sellers will deliver
       to the holder the number of shares of Common Stock that the holder is
       entitled to receive at that time pursuant to the terms of the DECS
       (subject to the right of each seller to deliver cash in lieu of the
       Common Stock).

   Under this approach, the tax consequences of holding a DECS will be as
described below. However, prospective investors in the DECS should be aware
that no ruling is being requested from the Internal Revenue

                                       32
<PAGE>

Service with regard to the DECS and that the Internal Revenue Service might
take a different view as to the proper characterization of the DECS or of the
prepaid forward contracts and of the tax consequences to an investor.

Tax Status of the Trust

   The trust will be taxable as a grantor trust owned solely by the present and
future holders of DECS for federal income tax purposes, and income received by
the trust will be treated as income of the holders in the manner set forth
below.

Tax Consequences to U.S. Holders

   Tax Basis of the Treasury Securities and the Forward Contracts. Each
investor will be considered to be the owner of its pro rata portion of the
Treasury Securities and the prepaid forward contracts in the trust. The cost to
the investor of the DECS will be allocated among the investor's pro rata
portion of the Treasury Securities and the prepaid forward contracts (in
proportion to the fair market values thereof on the date on which the investor
acquired the DECS) in order to determine the investor's tax basis in its pro
rata portion of the Treasury Securities and the prepaid forward contracts. It
is currently anticipated that   % and   % of the net proceeds of the offering
will be used by the trust to purchase the Treasury Securities and as a payment
to the sellers under the prepaid forward contracts, respectively.

   Recognition of Original Issue Discount on the Treasury Securities. The
Treasury Securities in the trust will consist of zero-coupon U.S. Treasury
securities. An investor will be required to treat its pro rata portion of each
Treasury Security in the trust as a bond that was originally issued on the date
the investor purchased its DECS and at an original issue discount equal to the
excess of the investor's pro rata portion of the amounts payable on such
Treasury Security over the investor's tax basis for the Treasury Security as
discussed above. The investor (whether on the cash or accrual method of tax
accounting) is required to include original issue discount (other than original
issue discount on short-term Treasury Securities as described below) in income
for federal income tax purposes as it accrues, in accordance with a constant
yield method, prior to the receipt of cash attributable to such income. Because
it is expected that more than 20% of the holders of DECS will be accrual basis
taxpayers, the investor will be required to include in income original issue
discount on any short-term Treasury Security (i.e., any Treasury Security with
a maturity of one year or less from the date it is purchased) held by the trust
as that original issue discount accrues. Unless an investor elects to accrue
the original issue discount on a short-term Treasury Security according to a
constant yield method based on daily compounding, the original issue discount
will be accrued on a straight-line basis. The investor's tax basis in a
Treasury Security will be increased by the amount of any original issue
discount included in income by the investor with respect to such Treasury
Security.

   Treatment of the Forward Contracts. Each investor will be treated as having
entered into a pro rata portion of the prepaid forward contracts and, at the
Exchange Date, as having received a pro rata portion of the Common Stock (or
cash, Reported Securities or combination thereof) delivered to the trust. Under
existing law, an investor will not recognize income, gain or loss upon entry
into the prepaid forward contracts. An investor should not be required under
existing law to include in income additional amounts over the term of the
prepaid forward contracts. See "--Possible Alternative Treatment," below,
however.

   Each of two sellers under two of the contracts representing in the aggregate
938,818 shares of Common Stock (plus up to an additional 645,000 shares of
Common Stock if the underwriters' overallotment option is exercised in full) is
a limited liability company "LLC", which in turn is wholly-owned by a grantor
retained annuity trust (each, a "GRAT"). Under the terms of the GRATs, the
GRATs will terminate in May 2001 and the trust estate will be distributed at
that time among several newly created trusts that will have different terms,
beneficiaries and trustees. It is possible that when the GRATs terminate an
investor would be treated as if it had exchanged its pro rata portion of the
prepaid forward contracts issued by the LLCs for a pro rata portion of new
prepaid forward contracts in a taxable exchange. In such a case, an investor
would recognize gain equal to the difference between the value of its pro rata
share of the prepaid forward contracts issued by the GRATs at

                                       33
<PAGE>

the time of the deemed exchange and the investor's basis in such pro rata
share. The investor's basis in each new prepaid forward contract would be equal
to the value of the contract at the time of the deemed exchange and the
investor's holding period in the new prepaid forward contract would begin on
the date after the deemed exchange. Gain on the deemed exchange would be long-
term capital gain if the investor had held the DECS for more than one year at
the time of the deemed exchange.

   Sale of the DECS. Upon a sale of all or some of an investor's DECS, an
investor will be treated as having sold its pro rata portion of the Treasury
Securities and prepaid forward contracts underlying the DECS. The selling
investor will recognize gain or loss equal to the difference between the amount
realized and the investor's aggregate tax bases in its pro rata portion of the
Treasury Securities and the prepaid forward contracts. Any gain or loss
generally will be long-term capital gain or loss if the investor has held the
DECS for more than one year. If there has been a deemed exchange with respect
to the forward contracts issued by the LLCs, any gain or loss with respect to
the investor's pro rata portion of such contracts will be long-term capital
gain if the investor has held the DECS for more than one year after the deemed
exchange. The distinction between capital gain or loss and ordinary income or
loss is important for purposes of the limitations on an investor's ability to
offset capital losses against ordinary income. In addition, individuals
generally are subject to taxation at a reduced rate on long-term capital gains.

   Distribution of the Common Stock. The delivery of Common Stock to the trust
pursuant to the prepaid forward contracts will not be taxable to the investors.
The distribution of Common Stock upon the termination of the trust will not be
taxable to the investors. An investor will have taxable gain or loss (which
will be short-term capital gain or loss) upon receipt of cash in lieu of
fractional shares of Common Stock distributed upon termination of the trust, in
an amount equal to the difference between the cash received and the portion of
the basis of the prepaid forward contracts allocable to fractional shares
(based on the relative number of fractional shares and full shares delivered to
the investor). Each investor's aggregate basis in its shares of Common Stock
will be equal to its basis in its pro rata portion of the prepaid forward
contracts less the portion of such basis allocable to any fractional shares of
Common Stock for which cash is received.

   Distribution of Cash. If an investor receives cash upon dissolution of the
trust or as a result of a seller's election to deliver cash, the investor will
recognize capital gain or loss equal to any difference between the amount of
cash received and its tax basis in the DECS at that time. Such gain or loss
generally will be long-term capital gain or loss if the investor has held the
DECS for more than one year at the Exchange Date. If there has been a deemed
exchange with respect to the forward contracts issued by the LLCs, any gain or
loss with respect to the investor's pro rata portion of such contracts will be
long-term capital gain if the investor has held the DECS for more than one year
after the deemed exchange.

   Distribution of Cash or Reported Securities as a Result of an Adjustment
Event. If as a result of an Adjustment Event, cash, Reported Securities, or a
combination of cash and Reported Securities is delivered pursuant to the
prepaid forward contracts, an investor will have taxable gain or loss upon
receipt equal to the difference between the amount of cash received, including
cash received in lieu of fractional Reported Securities, and its basis in its
pro rata portion of the prepaid forward contracts allocable to any shares of
Common Stock for which such cash or fractional Reported Securities were
received. In addition, if as a result of an Adjustment Event the Custodian
liquidates Treasury Securities, an investor will have taxable gain or loss upon
receipt of cash allocable to the liquidated Treasury Securities equal to the
difference between the amount of such cash and the investor's basis in its pro
rata portion of the Treasury Securities. Any gain or loss will be capital gain
or loss, and if the investor has held the DECS for more than one year, such
gain or loss generally will be long-term capital gain or loss. If there has
been a deemed exchange with respect to the forward contracts issued by the
LLCs, any gain or loss with respect to the investor's pro rata portion of such
contracts will be long-term capital gain if the investor has held the DECS for
more than one year after the deemed exchange. An investor's basis in any
Reported Securities received will be equal to its basis in its pro rata portion
of the prepaid forward contracts less the portion of such basis allocable to
any shares of Common Stock for which cash or fractional Reported Securities
were received. See "Investment Objectives and Policies--The Forward Contracts."

                                       34
<PAGE>

   Extension of Exchange Date. While not free from doubt, an extension of the
Exchange Date under a prepaid forward contract should not be a taxable event
and an investor therefore should not recognize gain upon such an extension.
Although there is no authority addressing the treatment of the cash
distribution paid on the extended Exchange Date (whether or not later
accelerated), the trust intends to file information returns with the Internal
Revenue Service on the basis that the cash distribution is ordinary income to
the investors. Investors should consult their own tax advisors concerning the
consequences of extending the Exchange Date, including the possibility that an
investor may be treated as realizing gain as a result of the extension and the
possibility that the cash distribution may be treated as a reduction in an
investor's tax basis in the DECS by analogy to the treatment of rebates or of
option premiums.

   Possible Alternative Treatment. The Internal Revenue Service may contend
that a DECS should be characterized for federal income tax purposes in a manner
different from the approach described above. For example, the Internal Revenue
Service might assert that the prepaid forward contracts should be treated as
contingent debt obligations of the sellers that are subject to Treasury
regulations governing contingent payment debt instruments. If the Internal
Revenue Service were to prevail in making such an assertion, original issue
discount would accrue with respect to the prepaid forward contracts at a
"comparable yield" for the sellers under the prepaid forward contracts,
determined at the time the prepaid forward contracts are entered into. An
investor's pro rata portion of original issue discount in respect of the
prepaid forward contracts and original issue discount in respect of the
Treasury Securities might exceed the aggregate amount of the quarterly cash
distributions to the investor. In addition, under this treatment, the investor
would be required to treat any gain realized on the sale, exchange or
redemption of the DECS as ordinary income to the extent that such gain is
allocable to the prepaid forward contracts. Any loss realized on such sale,
exchange or redemption that is allocable to the prepaid forward contracts would
be treated as an ordinary loss to the extent of the investor's original issue
discount inclusions with respect to the prepaid forward contracts, and as
capital loss to the extent of loss in excess of such inclusions. It is also
possible that the Internal Revenue Service could take the view that an investor
should include in income the amount of cash actually received each year in
respect of the DECS, or that the DECS as a whole constitute a contingent
payment debt instrument subject to the rules described above.

   Fees and Expenses of the Trust. An investor's pro rata portion of the
expenses in connection with the organization of the trust, underwriting
discounts and commissions and other offering expenses should be includible in
the cost to the owner of the DECS. However, there can be no assurance that the
Internal Revenue Service will not take a contrary view. If the Internal Revenue
Service were to prevail in treating such expenses as excludable from the
investor's cost of the DECS, such expenses would not be includible in the basis
of the assets of the trust and should instead be amortizable and deductible
over the term of the trust. If such expenses were treated as amortizable and
deductible, an individual investor who itemizes deductions would be entitled to
amortize and deduct (subject to any other applicable limitations on itemized
deductions) such expenses over the term of the trust only to the extent that
such amortized annual expenses together with the investor's other miscellaneous
deductions exceed 2% of such investor's adjusted gross income.

   Proposed Legislation. Proposed legislation currently under consideration in
Congress would (if enacted into law in its current form) recharacterize some or
all of the net long-term capital gain arising from certain "constructive
ownership" transactions entered into after July 11, 1999 as ordinary income,
and would impose an interest charge on any such ordinary income. The proposed
legislation would have no immediate application to forward contracts in respect
of the stock of a domestic operating company, including the DECS transaction.
The proposed legislation would, however, grant discretionary authority to the
U.S. Treasury Department to promulgate regulations to expand the scope of
"constructive ownership" transactions to include forward contracts in respect
of the stock of all corporations. The proposed legislation separately would
direct the Treasury to promulgate regulations excluding from the scope of the
legislation a forward contract that does not convey "substantially all" of the
economic return on an underlying asset (which category may include the DECS
transaction). It is not possible to predict whether legislation addressing
constructive ownership transactions will be enacted by Congress, the form or
effective date of any such legislation, or the form or effective date that any
Treasury regulations promulgated thereunder might take.

Non-U.S. Holders

   In the case of an investor that is a non-resident alien individual or
foreign corporation (a "Non-U.S. Holder"), payments made with respect to the
DECS should not be subject to U.S. withholding tax, provided that the investor
complies with applicable certification requirements (including in general the
furnishing of an Internal Revenue Service Form W-8 or a substitute form). Any
capital gain realized upon the sale or other disposition of the DECS by a Non-
U.S. Holder generally will not be subject to U.S. federal income tax if
(a) such gain is not effectively connected with a U.S. trade or business and
(b) in the case of an individual, (i) the individual is not present in the
United States for 183 days or more in the taxable year of the sale or other
disposition, and (ii) the gain is not attributable to a fixed place of business
maintained by the individual in the United States.

   A Non-U.S. Holder of the DECS that is subject to U.S. federal income
taxation on a net income basis with respect to the DECS should see the
discussion in "--Tax Consequences to U.S. Holders."

Backup Withholding Tax and Information Reporting

   An investor in a DECS may be subject to information reporting and to backup
withholding tax at a rate of 31 percent of certain amounts paid to the investor
unless the investor (a) is a corporation or comes within certain other exempt
categories and, when required, provides proof of such exemption or (b) provides
a correct taxpayer identification number, certifies as to no loss of exemption
from backup withholding tax and otherwise complies with applicable requirements
of the backup withholding tax rules. Information reporting and backup
withholding tax will not apply to payments made to an owner of a DECS that is a
Non-U.S. Holder if such owner (a) is the beneficial owner of the DECS and
certifies as to its non-U.S. status, (b) is not the beneficial owner of the
DECS, but the beneficial owner of the DECS certifies as to its non-U.S. status,
or (c) otherwise establishes an exemption, provided that the trust or its agent
does not have actual knowledge that the investor or the beneficial owner is a
U.S. person.

   Payment of the proceeds from the sale of a DECS to or through a foreign
office of a broker will not be subject to information reporting or backup
withholding tax, except that if the broker is (1) a U.S. person for U.S.
federal income tax purposes, (2) a controlled foreign corporation for U.S. tax
purposes, (3) a foreign person 50 percent or more of whose gross income from
all sources for the three-year period ending with the close of its taxable year
preceding the payment was effectively connected with a U.S. trade or business
or (4) with respect to payments made after December 31, 2000, a foreign
partnership that, at any time during its taxable year is 50% or more (by income
or capital interest) owned by U.S. persons or is engaged in the conduct of U.S.
trade or business, information reporting may apply to such payments. Payment of
the proceeds from a sale of a DECS to or through the U.S. office of a broker is
subject to information reporting and backup withholding tax unless the investor
or beneficial owner certifies as to its non-U.S. status or otherwise
establishes an exemption from information reporting and backup withholding.

   Any amounts withheld under the backup withholding tax rules are not an
additional tax and may be credited against a U.S. Holder's U.S. federal income
tax liability, provided that the required information is furnished to the
Internal Revenue Service.

   Recently issued Treasury regulations may change the certification procedures
relating to withholding and backup withholding on certain amounts paid to Non-
U.S. Holders after December 31, 2000. Prospective investors should consult
their tax advisors regarding the effect, if any, of such new Treasury
regulations on an investment in the DECS.

</TABLE>

   The underwriting agreement provides that the obligations of the several
underwriters to purchase the DECS included in this offering are subject to
approval of certain legal matters by counsel and to certain other conditions.
The underwriters are obligated to purchase all the DECS (other than those
covered by the over-allotment option described below) if they purchase any of
the DECS.

   The underwriters, for whom Salomon Smith Barney Inc. and Goldman, Sachs &
Co. are acting as representatives, propose to offer some of the DECS directly
to the public at the public offering price set forth on the cover page of this
prospectus and some of the DECS to certain dealers at the public offering price
less a concession not in excess of $   per DECS. The underwriters may allow,
and such dealers may reallow, a concession not in excess of $   per DECS on
sales to certain other dealers. After the initial offering of the DECS to the
public, the public offering price and such concessions may be changed by the
representatives. The sales load of $   per DECS is equal to   % of the initial
public offering price.

   The underwriting agreement provides that the sellers will pay to the
underwriters $ per DECS as compensation for underwriting the DECS. As described
under "Fees and Expenses," the sellers will reimburse Salomon Smith Barney Inc.
on the closing date for certain expenses incurred in establishing the trust and
registering the DECS, except that Salomon Smith Barney Inc. and Goldman, Sachs
& Co. have agreed to bear the first $500,000 of such expenses.

   The trust has granted to the underwriters an option, exercisable for 30 days
from the date of this prospectus, to purchase up to 645,000 additional DECS at
the same price per DECS as the initial DECS purchased by the underwriters. The
underwriters may exercise such option solely for the purpose of covering over-
allotments, if any, in connection with this offering. To the extent such option
is exercised, each underwriter will be obligated, subject to certain
conditions, to purchase a number of additional DECS approximately proportionate
to such underwriter's initial purchase commitment. In addition, Salomon Smith
Barney purchased DECS in connection with the organization of the trust.

   Crown Castle, its executive officers and the sellers have agreed that, for a
period of 45 days from the date of this prospectus, they will not, without the
prior written consent of Salomon Smith Barney Inc., as representative of the
underwriters, offer, sell, contract to sell, or otherwise dispose of, any
shares of common stock of Crown Castle or any securities convertible into, or
exercisable or exchangeable for, common stock. Salomon Smith Barney Inc. in its
sole discretion may release any of the securities subject to these lock-up
agreements at any time without notice. However, this agreement will not
restrict the ability of Crown Castle and the sellers to take any of the actions
listed above in connection with the offering by the trust of the DECS or any
delivery of shares of Crown Castle common stock pursuant to the terms of the
DECS.

   The DECS will be a new issue of securities with no established trading
market. The trust has applied to have the DECS approved for listing on the
Nasdaq National Market under the symbol "   ." The underwriters intend to make
a market in the DECS, subject to applicable laws and regulations. However, the
underwriters are not obligated to do so and any such market-making may be
discontinued at any time at the sole discretion of the underwriters without
notice. Accordingly, no assurance can be given as to the liquidity of such
market.

   In connection with the formation of the trust, Salomon Smith Barney Inc.
subscribed for and purchased DECS for a purchase price of $100. Under the
prepaid forward contracts, the sellers will be obligated to deliver to the
trust Crown Castle common stock in respect of such DECS on the same terms as
the DECS offered hereby. Salomon Smith Barney Inc. sponsored the formation of
the trust for purposes of this offering, including selecting its initial
Trustees.

   Pursuant to the prepaid forward contracts, the trust has agreed, subject to
the terms and conditions set forth therein, to purchase from the sellers a
number of shares of Crown Castle common stock equal to the total number of DECS
to be purchased by the Underwriters from the trust pursuant to the underwriting
agreement (including any DECS to be purchased by the Underwriters upon exercise
of the over-allotment option plus the number of DECS purchased by Salomon Smith
Barney in connection with the organization of the trust). Pursuant to the terms
of the prepaid forward contracts, each seller will deliver to the trust at the
Exchange Date a number of shares of Crown Castle common stock (or, at the
option of each seller, the cash equivalent) and/or such other consideration as
permitted or required by the terms of the prepaid forward contracts, that are
expected to have the same value as the shares of Crown Castle common stock
delivered pursuant to the DECS. The closing of the offering of the DECS is
conditioned upon execution of the prepaid forward contracts by the sellers and
the trust.

   In connection with the DECS offering, the underwriters may over-allot, or
engage in syndicate covering transactions, stabilizing transactions and penalty
bids. Over-allotment involves syndicate sales of DECS or Crown Castle common
stock in excess of the number of DECS to be purchased by the underwriters in
the offering, which creates a syndicate short position. Syndicate covering
transactions involve purchases of the DECS or the Crown Castle common stock in
the open market after the distribution has been completed in order to cover
syndicate short positions. Stabilizing transactions consist of certain bids or
purchases of DECS or common stock made for the purpose of preventing or
retarding a decline in the market price of the DECS or common stock while the
offering is in progress. Penalty bids permit the underwriters to reclaim a
selling concession from a syndicate member when Salomon Smith Barney Inc. or
Goldman, Sachs & Co., in covering syndicate short positions or making
stabilizing purchases, repurchase DECS or common stock originally sold by the
syndicate member. These activities may cause the price of DECS or common stock
to be higher than the price that otherwise would exist in the open market in
the absence of such transactions. These transactions may be effected on the
Nasdaq National Market or in the over-the-counter market, or otherwise and, if
commenced, may be discontinued at any time.

   In addition, in connection with this offering, certain of the underwriters
(and selling group members) may engage in passive market making transactions in
the DECS or common stock on the Nasdaq National Market, prior to the pricing
and completion of the DECS offering. Passive market making consists of
displaying bids on the Nasdaq National Market no higher than the bid prices of
independent market makers and making purchases at prices no higher than those
independent bids and effected in response to order flow. Net purchases by a
passive market on each day are limited to a specified percentage of the passive
market maker's average daily trading volume in the common stock during a
specified period and must be discontinued when such limit is reached. Passive
market making may cause the price of the common stock to be higher than the
price that otherwise would exist in the open market in the absence of such
transactions. If passive market making is commenced, it may be discontinued at
any time.

   The underwriters have performed certain investment banking and advisory
services for Crown Castle from time to time for which they have received
customary fees and expenses. The underwriters may, from time to time, engage in
transactions with and perform services for Crown Castle in the ordinary course
of its business.

   Crown Castle and the sellers have agreed to indemnify the underwriters
against certain liabilities, including liabilities under the Securities Act of
1933, or to contribute to payments the underwriters may be required to make in
respect of any of those liabilities. Crown Castle has agreed to pay $750,000 on
behalf of the sellers in respect of fees, expenses and other compensation in
connection with the DECS offering.

             NOTES TO STATEMENT OF ASSETS, LIABILITIES AND CAPITAL

                              August 5, 1999

I. Organization

   DECS Trust V, organized as a Delaware business trust on April 22, 1999, is a
closed-end management investment company registered under the Investment
Company Act of 1940. The term of the trust is anticipated to expire in the year
2002; however, the exact date will be determined in the future. The trust may
be dissolved prior to its planned termination date under certain circumstances
as outlined in the registration statement.

   The trust has registered 5,645,000 DECS representing shares of beneficial
interest in the trust. The only securities that the trust is authorized to
issue are the DECS. Each of the DECS represents the right to receive
(a) quarterly distributions during the term of the trust, and (b) upon the
conclusion of the term of the trust (the "Exchange Date"), certain shares of
common stock (the "Common Stock") or cash with an equivalent value (such
amounts determined as described in the registration statement). The DECS are
not subject to redemption prior to the Exchange Date or the earlier termination
of the trust. The trust will hold a series of zero-coupon U.S. Treasury
securities and one or more prepaid forward contracts relating to the Common
Stock. The business activities of the trust are limited to the matters
discussed above. The trust will be treated as a grantor trust for U.S. federal
income tax purposes.

   On August 4, 1999, the trust issued one DECS to Salomon Smith Barney Inc. in
consideration for a purchase price of $100.

II. Organizational Costs, Fees and Expenses

   Organizational costs and ongoing fees of the trust will be borne by Salomon
Smith Barney Inc.

III. Management and Administration of Trust

   The internal operation of the trust will be managed by its trustees; the
trust will not have a separate investment adviser. The trust will be overseen
by three trustees, and its daily administration will be carried out by The Bank
of New York as the administrator. The Bank of New York will also serve as the
trust's custodian, paying agent, registrar and transfer agent with respect to
the DECS.

Item 29. Indemnification

   The Underwriting Agreement (Exhibit 2(h) to this Registration Statement)
provides for indemnification.

   The Amended and Restated Declaration of Trust filed as Exhibit 2(a)(1)(C)
to this Registration Statement provides for indemnification to each Trustee
against any claim or liability incurred in acting as Trustee of the trust,
except in the case of willful misfeasance, bad faith, gross negligence or
reckless disregard of the trustee's duties. The Custodian Agreement,
Administration Agreement and Paying Agent Agreement filed as Exhibits 2(j),
2(k)(1) and 2(k)(2) to this Registration Statement provide for indemnification
to the Custodian, Administrator and Paying Agent against any loss or expense
incurred in the performance of their obligations under the respective
agreements, unless such loss or expense is due to willful misfeasance, bad
faith, gross negligence or reckless disregard of their obligations. The Fund
Indemnity Agreement filed as Exhibit 2(k)(6) to this Registration Statement
provides that Salomon Smith Barney will indemnify the trust for certain
indemnification expenses incurred under the Amended and Restated Declaration
of Trust, the Custodian Agreement, the Administration Agreement and the Paying
Agent Agreement.

   Insofar as indemnification for liabilities arising under the Securities Act
may be permitted to directors, officers and controlling persons of the
Registrant, pursuant to the foregoing provisions, or otherwise, the Registrant
has been advised that in the opinion of the Securities and Exchange Commission
such indemnification is against public policy as expressed in the Securities
Act and is, therefore, unenforceable. In the event that a claim for
indemnification against such liabilities (other than the payment by the
Registrant of expenses incurred or paid by a director, officer or controlling
person of the Registrant in the successful defense

                                      C-2
<PAGE>

of any action, suit or proceeding) is asserted by such director, officer or
controlling person in connection with the securities being registered, the
Registrant will, unless in the opinion of its counsel the matter has been
settled by controlling precedent, submit to a court of appropriate jurisdiction
the question whether such indemnification by it is against public policy as
expressed in the Securities Act and will be governed by the final adjudication
of such issue.

Item 30. Business and other Connections of Investment Adviser

   Not applicable.

Item 31. Location of Accounts and Records

   The accounts, books and other documents required to be maintained by Section
31(a) of the Investment Company Act of 1940 and the Rules thereunder are

   (b) The Registrant hereby undertakes that (i) for the purpose of determining
any liability under the Securities Act, the information omitted from the form
of prospectus filed as part of this Registration Statement in reliance upon
Rule 430A and contained in a form of prospectus filed by the registrant under
Rule 497(h) under the Securities Act shall be deemed to be part of this
Registration Statement as of the time it was declared effective; (ii) for the
purpose of determining any liability under the Securities Act, each post-
effective amendment that contains a form of prospectus shall be deemed to be a
new registration statement relating to the securities offered therein, and the
offering of the securities at that time shall be deemed to be the initial bona
fide offering thereof.

acceptance of the Trustees under the terms of this Agreement.  The Sponsor
hereby waives the thirty (30) day notice requirement of Section 5 of the
Original Agreement.  The Initial Sponsor has heretofore deposited with the
Initial Trustees the sum of $1 to accept and hold in trust hereunder until the

donated to an organization satisfying the requirements of Section 170(c)(2) of
the Code selected by unanimous consent of the Trustees.

     Agreement terminates, or the agent of the Trust thereunder resigns or is
     discharged, to appoint a substitute agent and enter into a new agreement
     with such substitute agent containing provisions substantially similar to
     those contained in the agreement being terminated; provided that in any

     however, that subsequent to the determination of the public offering price
     per DECS and related underwriting discount for the DECS to be sold to the
     Underwriters but prior to the sale of the DECS to the Underwriters, the
     DECS originally issued to the Sponsor shall be split into a greater number
     of DECS, with any fractional shares being rounded down to the nearest
     integral number, so that immediately following such split the value of each
     DECS held by the Sponsor will equal the aforesaid public offering price;

          (d) to select independent public accountants and, subject to the
     provisions of Section 8.5 hereof, to engage such independent public

     as necessary or advisable to carry out the purposes of the Trust, subject
     to the provisions hereof and applicable law, including, without limitation,

     and, subject to the adjustments and exceptions set forth in the Contracts,
     the Contracts shall entitle the Trust to receive from the Sellers on the
     Exchange Date the Shares and/or Reported Securities subject thereto (or, if
     one or more the Sellers elects the Cash Delivery Option under the
     Contracts, the amount in cash specified in such Contracts in respect
     thereof) so that the Trust may execute the Exchange with the Holders; and

          (b) to purchase for settlement at the Closing Date, and at the Option
     Closing Date, as appropriate, with the proceeds of the sale of the DECS,

     notice pursuant to Section 5.4(b)  of the Contracts of an event requiring

     of any property as provided in the

     or more Sellers elect the Cash Delivery Option under his or her Contract,
     the amount in cash) required to be delivered by each of the related Sellers
     under Sections 1.1 and 1.3 of such Contracts or, if an Adjustment Event
     shall have occurred, the amount of cash required to be delivered by such
     Sellers, and the number of Reported Securities permitted to be delivered by
     such Sellers in lieu of all or a portion of such cash, all as provided in
     Section 6.2 of the Contracts, and to furnish notice of the amounts so
     determined to the Collateral Agent and such Sellers;

          (e) Distribution of Exchange Consideration.  Unless an Event of
              --------------------------------------
     Default or an Adjustment Event shall have occurred or one or more Sellers
     elect the Cash Delivery Option under the Contracts (in which event the cash
     received in respect thereof shall be distributed pro rata to the Holders of
     the DECS):

               (i) Determination of Fractional Shares.  To determine, on the
                   ----------------------------------
          Exchange Date under any of the Contracts: (a)  for each Holder of

          and to distribute to the Holders, pro rata in accordance with the
          fractional shares to which they would otherwise have been entitled,
          the aggregate proceeds of such sale (net of any brokerage or related
          expenses); and

          re-issued as follows: (a)  for and in the name of each Holder (other
          than the Depositary) who holds DECS in definitive form, if any, the
          Transfer Agent and Registrar shall be instructed to issue definitive
          certificates representing a number of Shares equal to such Holder's
          pro rata share of the total number of Shares delivered to the Trust
          under such Contracts, rounded down to the nearest integral number and
          the Trustees shall cause the delivery of such re-registered and re-
          issued Shares to each respective Holder; and (b)  the Transfer Agent
          and Registrar shall be instructed to transfer all remaining Shares to
          the account of the Custodian held through the Depositary, who shall
          then be instructed to transfer and credit such Shares to each
          Participant who holds DECS, with each Participant receiving its pro
          rata share of the total Shares delivered to the Trust on such Exchange
          Date, reduced by the aggregate fractional shares allocable to such
          Participant as described in (i) above;

               (iv) Distribution of Other Property.  To distribute on the
                    ------------------------------
          Exchange Date under any of the Contracts to each Holder of DECS such
          Holder's pro rata share of the total number or amount of each other
          type of property owned by the Trust at the Exchange Date and subject
          to such Contracts, rounded to the nearest integral number;

               (v) Record Date.  The distributions described in this paragraph
                   -----------

under Section 8.3(c)  hereof shall be made through such executing brokers or to

shall designate in writing to the Paying Agent, taking into account such factors
as price, commission, size of order, difficulty of execution and brokerage skill
required.

          SECTION 2.9 Limitations on Trustees' Powers'.  The Trustees are not
                      -------------------------------

     to be taken that would or could cause the Trust not to be a "grantor trust"
     owned solely by the present and future Holders under the Code.

          SECTION 2.10  Legal Title to Trust Property.  Legal title to the Trust
                        -----------------------------
Estate shall be vested at all times in the Trust as a separate legal entity
except where applicable law in any jurisdiction requires title to any part of
the Trust Estate to be vested in a trustee or trustees, in which case legal
title shall be deemed to be vested in the Trustees, a co-trustee and/or a
separate trustee, as the case may be.

          SECTION 2.11  Situs of Trust.  The Trust shall be located and
                        --------------

                                  ARTICLE III

                             ACCOUNTS AND PAYMENTS

          SECTION 3.1 The Trust Account.  The Trustees shall, upon issuance of
                      -----------------
the DECS, establish with the Paying Agent an account to be called the "Trust
Account".  All moneys received by the Trust or the Trustees in respect of the

at the close of business on the preceding Record Date, at the post office
address of the Holder appearing on the books of the Trust or Paying Agent or by

equal

                                       11
<PAGE>

to such Holder's pro rata share of the Quarterly Distribution, (or, as the case
may be, the Additional Distribution) computed as of the close of business on
such Distribution Date.


          SECTION 3.4 Segregation.  All moneys and other assets deposited or
                      -----------
received by the Trust or the Trustees hereunder shall be held by them in trust
as part of the Trust Estate until required to be disbursed or otherwise disposed
of in accordance with the provisions of this Trust Agreement, and the Trust or
the Trustees shall handle such moneys and other assets in such manner as shall
constitute the segregation and holding in trust within the meaning of the
Investment Company Act.

          SECTION 3.5 Temporary Investments.  To the extent necessary to enable
                      ---------------------
the Paying Agent to make the next succeeding Quarterly Distribution, any moneys

invested as soon as possible by the Paying Agent in Temporary Investments
maturing no later than the Business Day preceding the next following
Distribution Date.  Except as otherwise specifically provided herein or in the
Paying Agent Agreement, the Paying Agent shall not have the power to sell,
transfer or otherwise dispose of any Temporary Investment prior to the maturity
thereof, or to acquire additional Temporary Investments.  The Paying Agent shall

time by the Trustees or pursuant to standing instructions from the Trustees to
the Administrator, and the Administrator and/or Paying Agent shall have no
liability to the Trust or any Holder or any other Person with respect to any

                                   REDEMPTION

          SECTION 4.1 Redemption.  The Trustees shall have no right or
                      ----------
obligation to redeem DECS.

                                   ARTICLE V

              ISSUANCE OF CERTIFICATES; REGISTRY; TRANSFER OF DECS

          SECTION 5.1 Form of Certificate.  Each Certificate evidencing DECS
                      -------------------
shall be countersigned manually or in facsimile by the Managing Trustee and
countersigned manually by the Paying Agent in substantially the form of Exhibit
A hereto with the blanks appropriately filled in, shall be dated the date of
execution and delivery by the Paying Agent and shall represent a fractional
undivided interest in the Trust, the numerator of which fraction shall be the
number of DECS set forth on the face of such Certificate and the denominator of
which shall be the total number of DECS outstanding at that time.  All DECS
shall be issued in registered form and shall be numbered serially.

          The DECS delivered to the Underwriters on the Closing Date and on any
settlement date under Section 4(b) of the Underwriting Agreement will be issued
in the form of a

                                       12
<PAGE>

global Certificate or Certificates representing the DECS issued to the
Underwriters, to be delivered to the Depositary by or on behalf of the Trust.
Such Certificate or Certificates shall initially be registered on the books and
records of the Trust in the name of Cede & Co., the nominee of DTC, and no
beneficial owner of such DECS will receive a definitive Certificate representing
such beneficial owner's interest in such DECS, except as provided in the next
paragraph. Unless and until definitive, fully registered Certificates have been
issued pursuant to the next paragraph, the Trust shall be entitled to deal with
the Depositary for all purposes of this Agreement as the Holder and the sole
holder of the Certificates and shall have no obligation to the beneficial owners
thereof, and none of the Trust, the Trustees, or any agent of the Trust or the
Trustees shall have any liability with respect to or responsibility for the
records of the Depositary.

          If the Depositary elects to discontinue its services as securities
depository and a successor depositary is not appointed by the Trust within 90
days, then definitive Certificates shall be prepared by the Trust.  Upon
surrender of the global Certificate or Certificates accompanied by registration
instructions, the Trustees shall cause definitive Certificates to be delivered
to the beneficial owners in accordance with the instructions of the Depositary.
Neither the Trustees nor the Trust shall be liable for any delay in delivery of
such instructions and may conclusively rely on, and shall be protected in
relying on, such instructions.

          Pending the preparation of definitive Certificates, the Trustees may
execute and the Paying Agent shall authenticate and deliver temporary
Certificates (printed, lithographed, typewritten or otherwise reproduced, in
each case in form satisfactory to the Paying Agent).  Temporary Certificates
shall be issuable as registered Certificates substantially in the form of the
definitive Certificates but with such omissions, insertions and variations as
may be appropriate for temporary Certificates, all as may be determined by the
Trustees with the concurrence of the Paying Agent.  Every temporary Certificate
shall be executed by the Managing Trustee and be authenticated by the Paying
Agent upon the same conditions and in substantially the same manner, and with
like effect, as the definitive Certificates.  Without unreasonable delay the
Managing Trustee shall execute and shall furnish definitive Certificates and
thereupon temporary Certificates may be surrendered in exchange therefor without
charge at each office or agency of the Paying Agent and the Paying Agent shall
authenticate and deliver in exchange for such temporary Certificates definitive
Certificates for a like aggregate number of DECS.  Until so exchanged, the
temporary Certificates shall be entitled to the same benefits hereunder as
definitive Certificates.

          SECTION 5.2 Transfer of DECS; Issuance, Transfer and Exchange of
                      ----------------------------------------------------
Certificates.  DECS may be transferred by the Holder thereof by presentation and
- ------------
surrender of properly endorsed Certificates at the office of the Paying Agent,
accompanied by such documents executed by the Holder or his authorized attorney
as the Paying Agent deems necessary to evidence the authority of the person
making the transfer.  Certificates issued pursuant to this Trust Agreement are
exchangeable for one or more other Certificates representing an equal aggregate
number of DECS and all Certificates issued as may be requested by the Holder and
deemed appropriate by the Paying Agent shall be issued in denominations of one
DECS or any multiple thereof.  The Paying Agent may deem and treat the person in
whose name any DECS shall be registered upon the books of the Paying Agent as
the owner of such DECS for all purposes hereunder and the Paying Agent shall not
be affected by any notice to the

                                       13
<PAGE>

contrary. The transfer books maintained by the Paying Agent for the purposes of
this Section 5.2 hereof shall include the name and address of the record owners
of the DECS and shall be closed in connection with the termination of the Trust
pursuant to Section 8.3 hereof.

          A sum sufficient to cover any tax or other governmental charge that
may be imposed in connection with any such transfer shall be paid to the Paying
Agent by the Holder.  A Holder may be required to pay a fee for each new
Certificate to be issued pursuant to the preceding paragraph in such amount as
may be specified by the Paying Agent and approved by the Trustees.

          All Certificates cancelled pursuant to this Trust Agreement may be
voided by the Paying Agent in accordance with the usual practice of the Paying
Agent or in accordance with the instructions of the Trustees; provided, however,
that the Paying Agent shall not be required to destroy cancelled Certificates.

          The Paying Agent may adopt other reasonable rules and regulations for
the registration, transfer and tender of DECS as it may, in its discretion, deem
necessary.

          SECTION 5.3 Replacement of Certificates.  In case any Certificate
                      ---------------------------
shall become mutilated or be destroyed, stolen or lost, the Paying Agent shall
execute and deliver a new Certificate in exchange and substitution therefor upon
the Holder's furnishing the Paying Agent with proper identification and
satisfactory indemnity, complying with such other reasonable regulations and
conditions as the Paying Agent may prescribe and paying such expenses and
charges, including any bonding fee, as the Paying Agent may incur or reasonably
impose; provided that if the Trust has terminated or is in the process of
terminating, the Paying Agent, in lieu of issuing such new Certificate, may,
upon the terms and conditions set forth herein, make the distributions set forth
in Section 8.3(c)  hereof.  Any mutilated Certificate shall be duly surrendered
and cancelled before any duplicate Certificate shall be issued in exchange and
substitution therefor.  Upon issuance of any duplicate Certificate pursuant to
this Section 5.3 hereof, the original Certificate claimed to have been lost,
stolen or destroyed shall become null and void and of no effect, and any
protected purchaser thereof shall have only such rights as are afforded under
Article 8 of the Uniform Commercial Code to a Holder presenting a Certificate
for transfer in the case of an overissue.

          SECTION 5.4 Limitation on Liability.  Pursuant to Section 3803(a) of
                      -----------------------

organized under the General Corporation Law of the State of Delaware.

          SECTION 5.5. General Provisions Regarding the DECS.
                       -------------------------------------

          (a)  The consideration received by the Trust for the issuance of the
DECS shall constitute a contribution to the capital of the Trust and shall not
constitute a loan to the Trust.

          (b)  Upon issuance of the DECS as provided in this Trust Agreement,
the DECS so issued shall be deemed to be validly issued, fully paid and non-
assessable.

                                       14
<PAGE>

          (c)   Every person, by virtue of having become a Holder in accordance
with the terms of this Trust Agreement, shall be deemed to have expressly
assented and agreed to the terms of, and shall be bound by, this Trust
Agreement.

                                   ARTICLE VI

                           ISSUANCE OF THE CONTRACTS

          SECTION 6.1 Execution of the Contracts.  The Contracts shall be
                      --------------------------
countersigned manually or in facsimile by the Managing Trustee and executed
manually by each of the Sellers and shall be dated the date of execution and
delivery by each of the Sellers.

                                  ARTICLE VII

                                    TRUSTEES

          SECTION 7.1 Trustees.  The Trust shall have three Trustees who shall
                      --------
initially be elected by the Initial Trustee.  One Trustee shall be the Managing
Trustee and, as such, is authorized to execute documents and instruments on
behalf of the Trust.  The Managing Trustee will be appointed by resolution of
the Trustees.  Each Trustee shall serve until the next regular annual or special
meeting of Holders called for the purpose of electing Trustees and, then, until
such Trustee's successor is duly elected and qualified.  Holders may not
cumulate their votes in the election of Trustees.  Each Trustee shall not be
considered to have qualified for the office unless such Trustee shall agree to
be bound by the terms of this Trust Agreement and shall evidence his consent by
executing this Trust Agreement or a supplement hereto.

          SECTION 7.2 Vacancies.  Any vacancy in the office of a Trustee may be
                      ---------
filled in compliance with Sections 10 and 16 of the Investment Company Act by
the vote, within thirty days, of the remaining Trustees; provided that if
required by Section 16 of the Investment Company Act, the Trustees shall
forthwith cause to be held as promptly as possible and in any event within sixty
days (unless the Commission by order shall extend such period) a meeting of
Holders for the purpose of electing Trustees in compliance with Sections 10 and
16 of the Investment Company Act.  Until a vacancy in the office of any Trustee
is filled as provided above, the remaining Trustees in office, regardless of
their number, shall have the powers granted to the Trustees and shall discharge
all the duties imposed upon the Trustees by this Trust Agreement.  Election
shall be by the affirmative vote of Holders of a majority of the DECS entitled
to vote present in person or by proxy at a special meeting of Holders called for
the purpose of electing any Trustee.  Each individual Trustee shall be at least
21 years of age and shall not be under any legal disability.  No Trustee who is
an "interested person", as defined in the Investment Company Act, may assume
office if it would cause the composition of the Trustees of the Trust not to be
in compliance with the percentage limitations on interested persons in Section
10 of the Investment Company Act.  Trustees need not be Holders.  Notice of the
appointment or election of a successor Trustee shall be mailed promptly after
acceptance of such appointment by the successor Trustee to each Holder.

          SECTION 7.3 Powers.  The Trust will be managed solely by the Trustees,
                      ------
who will, subject to the provisions of Article II hereof, have complete and
exclusive control over the management, conduct and operation of the Trust's
business, and shall have the rights, powers

                                       15
<PAGE>

and authority of a board of directors of a corporation organized under Delaware
law. The Trustees shall have fiduciary responsibility for the safekeeping and
use of all funds and assets of the Trust and shall not employ, or permit another
to employ, such funds or assets in any manner except for the exclusive benefit
of the Trust and except in accordance with the terms of this Trust Agreement.
Subject to the continuing supervision of the Trustees and as permitted by
applicable law, the functions of the Trust shall be performed by the Custodian,
the Paying Agent, the Administrator and such other entities engaged to perform
such functions as the Trustees may determine, including, without limitation, any
or all administrative functions.

          SECTION 7.4 Meetings.  Meetings of the Trustees shall be held from
                      --------
time to time upon the call of any Trustee on not less than 48 hours' notice
(which may be waived by any or all of the Trustees in writing either before or
after such meeting or by attendance at the meeting unless the Trustee attends
the meeting for the express purpose of objecting to the transaction of any
business on the ground that the meeting has not been lawfully called or
convened).  The Trustees shall act either by majority vote of the Trustees
present at a meeting at which at least a majority of the Trustees then in office
are present or by a unanimous written consent of the Trustees without a meeting.
Except as otherwise required under the Investment Company Act, all or any of the
Trustees may participate in a meeting of the Trustees by means of a conference
telephone call or similar communications equipment by means of which all persons
participating in the meeting can hear each other, and participation in a meeting
by means of such communications equipment shall constitute presence in person at
such meeting.

          SECTION 7.5 Resignation and Removal.  Any Trustee may resign and be
                      -----------------------
discharged of the trust created by the Trust Agreement by executing an
instrument in writing resigning as Trustee, filing the same with the
Administrator and sending notice thereof to the remaining Trustees, and such
resignation shall become effective immediately unless otherwise specified
therein.  Any Trustee may be removed in the event of incapacity by vote of the
remaining Trustees and for any reason by written declaration or vote of the
Holders of more than 66 2/3% of the outstanding DECS, notice of which vote shall
be given to the remaining Trustees and the Administrator.  The resignation,
removal or failure to reelect any Trustee shall not cause the termination of the
Trust.

          SECTION 7.6 Liability.  The Trustees shall not be liable to the Trust
                      ---------
or any Holder for any action taken or for refraining from taking any action
except in the case of willful misfeasance, bad faith, gross negligence or
reckless disregard of the duties of their office.  Specifically, without
limitation, the Trustees shall not be responsible for or in respect of the
recitals herein or the validity or sufficiency of this Trust Agreement or for
the due execution hereof by any other Person, or for or in respect of the
validity or sufficiency of DECS or certificates representing DECS and shall in
no event assume or incur any liability, duty or obligation to any Holder or to
any other Person, other than as expressly provided for herein.  The Trustees may
employ agents, attorneys, administrators, accountants and auditors, and shall
not be answerable for the default or misconduct of any such Persons if such
Persons shall have been selected with reasonable care.  Action in good faith may
include action taken in good faith in accordance with an opinion of counsel.  In
no event shall any Trustee be personally liable for any expenses with respect to
the Trust.  Each Trustee shall be indemnified from the Trust Account with
respect to any claim, liability, loss or expense incurred in acting as Trustee
of the Trust, including the costs and expenses of the defense against any such
claim or liability, except in the

                                       16
<PAGE>

case of willful misfeasance, bad faith, gross negligence or reckless disregard
of the duties of his office.

          SECTION 7.7 Compensation.  Each Trustee, other than a Trustee who is a
                      ------------
director, officer or employee of the Sponsor, any Underwriter, or the
Administrator or any affiliate thereof, shall receive a one-time, up-front fee
of $10,800, in respect of its annual fee and anticipated out-of-pocket expenses.
In addition, the Managing Trustee shall receive an additional one-time, up-front
fee of $3,600 for serving in such capacity.  The Trustees will not receive any
pension or retirement benefits.  In the event of the resignation or removal of a
Trustee, such Trustee shall remit to the Trust the portion of its fee ratable
for the period from the day of such resignation or removal through the Exchange
Date.

                                  ARTICLE VIII

                                 MISCELLANEOUS

          SECTION 8.1 Meetings of Holders.  The Trustees shall not hold annual
                      -------------------
or regular meetings of Holders except as set forth herein.  A special meeting
may be called at any time by the Trustees or upon petition of Holders of not
less than 51% of the DECS outstanding (unless substantially the same matter was
voted on during the preceding 12 months), and shall be called as provided in
Section 7.2 hereof (or as otherwise required by the Investment Company Act and
the rules and regulations thereunder, including, without limitation, when
requested by the Holders of not less than 10% of the DECS outstanding for the
purposes of voting upon the question of the removal of any Trustee or Trustees).
The Trustees shall establish, and notify the Holders in writing of, the record
date for each such meeting which shall be not less than 10 nor more than 50 days
before the meeting date.  Holders at the close of business on the record date
will be entitled to vote at the meeting.  The Administrator shall, as soon as
possible after any such record date (or prior to such record date if
appropriate), mail by first class mail to each Holder a notice of meeting and a
proxy statement and form of proxy in the form approved by the Trustees and
complying with the Investment Company Act and the rules and regulations
thereunder.  Except as otherwise specified herein or in any provision of the
Investment Company Act and the rules and regulations thereunder, any action may
be taken by vote of Holders of a majority of the DECS outstanding present in
person or by proxy if Holders of a majority of DECS outstanding on the record
date are so represented.  Each DECS shall have one vote and may be voted in
person or by duly executed proxy.  Any proxy may be revoked by notice in
writing, by a subsequently dated proxy or by voting in person at the meeting,
and no proxy shall be valid after eleven months following the date of its
execution.  Any investment company (as defined in Section 3 of the Investment
Company Act) owning DECS in excess of the limits imposed by Sections
12(d)(1)(A)(i) and 12(d)(1)(c)  of the Investment Company Act will be required
to vote its DECS in proportion to the votes of all other Holders.

          SECTION 8.2 Books and Records; Reports.  (a)  The Trustees shall keep
                      --------------------------
a certified copy or duplicate original of this Trust Agreement on file at the
office of the Trust and the office of the Administrator available for inspection
at all reasonable times during its usual business hours by any Holder.  The
Trustees shall keep proper books of record and account for all the transactions
under this Trust Agreement at the office of the Trust and the office of the
Administrator, and such books and records shall be open to inspection by any
Holder at all

                                       17
<PAGE>

reasonable times during usual business hours. The Trustees shall retain all
books and records in compliance with Section 31 of the Investment Company Act
and the rules and regulations thereunder.

          (b)  With each payment to Holders the Paying Agent shall set forth,
either in the instruments by means of which payment is made or in a separate
statement, the amount being paid from the Trust Account expressed as a dollar
amount per DECS and the other information required under Section 19 of the
Investment Company Act and the rules and regulations thereunder.  The Trustees
shall prepare and file or distribute reports as required by Section 30 of the
Investment Company Act and the rules and regulations thereunder.  The Trustees
shall prepare and file such reports as may from time to time be required to be
filed or distributed to Holders under any applicable state or Federal statute or
rule or regulation thereunder, and shall file such tax returns as may from time
to time be required under any applicable state or Federal statute or rule or
regulation thereunder.  One of the Trustees shall be designated by resolution of
the Trustees to make the filings and give the notices required by Rule 17g-1
under the Investment Company Act.

          (c)  In calculating the net asset value of the Trust as required by
the Investment Company Act, (i) the Treasury Securities shall be valued at the
mean between the last current bid and asked prices or, if quotations are not
available, as determined in good faith by the Trustees, (ii) short-term
investments having a maturity of 60 days or shall be valued at cost with accrued
interest or discount earned included in interest receivable and (iii) the
Contracts shall be valued at the mean of the bid prices received by the
Administrator from at least three independent broker-dealer firms unaffiliated
with the Trust to be named by the Trustees who are in the business of making
bids on financial instruments similar to the Contracts and with terms comparable
thereto.  In the event that the Trust (acting through the Administrator) is
unable to obtain valuations from three independent broker-dealer firms, as
required by clause (iii) of the preceding sentence, on a timely basis or without
unreasonable effort or expense, the Contracts shall be valued at the median of
bid prices received from two such broker-dealer firms.  In the event that the
Trust (acting through the Administrator) is unable to obtain a valuation for the
Contracts that it believes to be reasonable through the above method, valuation
shall be established at a level deemed to be fair and reflective of the market
value for the Contracts based on all appropriate factors relevant to the value
of the Contracts as set forth in pricing guidelines adopted by the Trustees.

          SECTION 8.3 Termination.  (a)  The Trust created hereby shall
                      -----------
dissolve, and its affairs be wound up, upon the earliest of (i) the date 90 days
after the execution of this Trust Agreement if (x) the DECS have not theretofore
been issued or (y) the net worth of the Trust is not at least $100,000 at such
time, (ii) the date of the repayment, sale or other disposition, as the case may
be, of all of the Contracts, the Treasury Securities and any other securities
held hereunder, (iii) the date 10 Business Days after the latest Exchange Date
under any of the Contracts (or, if all of the Contracts shall be accelerated
pursuant to Article VII thereof, 10 Business Days after the date on which the
Trust shall receive the Shares, cash or other property then required to be
delivered by each of the Sellers, or the proceeds of any sale of collateral
pursuant to the Collateral Agreements), and (iv) the date which is 21 years less
91 days after the death of the last survivor of all of the descendants of Joseph
P. Kennedy living on the date hereof.  The Trust is irrevocable, the Sponsor has
no right to withdraw any assets constituting a

                                       18
<PAGE>

portion of the Trust Estate, and the dissolution of the Sponsor shall not
operate to terminate the Trust. The death or incapacity of any Holder shall not
operate to terminate this Trust Agreement, nor entitle his legal representatives
or heirs to claim an accounting or to take any action or proceeding in any court
for a partition or winding up of the Trust, and shall not otherwise affect the
rights, obligations and liabilities of the parties hereto.

          (b)  Written notice of any dissolution shall be sent to Holders
specifying the record date for any distribution to Holders and the time of
dissolution as determined by the Trustees, upon which the books maintained by
the Paying Agent pursuant to Section 5.2 hereof shall be closed.

          (c)  To the extent permitted by applicable law, for purposes of
dissolution under Sections 8.3(a)(ii), (iii) and (iv) hereof, within five
Business Days after such dissolution, the Trustees shall effect the sale of any
remaining property of the Trust, and the Paying Agent shall distribute pro rata
as soon as practicable thereafter to each Holder, upon surrender for
cancellation of its Certificates, its interest in the Trust Estate.  Together
with the distribution to the Holders, the Trustees shall furnish the Holders
with a final statement as of the date of the distribution of the amount
distributable with respect to each DECS.

          (d)  Upon the winding up of the Trust and its dissolution, the
Managing Trustee shall cause the Certificate of Trust to be canceled by filing a
certificate of cancellation with the Office of the Secretary of State of the
State of Delaware in accordance with the provisions of Section 3810 of the Act.
Upon the dissolution of the Trust, the sale of Trust property and distribution
of the Trust Estate to the Holders, and the filing of the certificate of
cancellation, the Trust shall terminate and this Agreement shall be of no
further force or effect.

          SECTION 8.4 Amendment and Waiver.  (a)  This Trust Agreement, and any
                      --------------------
of the agreements referred to in Section 2.5(a) hereof, may be amended from time
to time by the Trustees for any purpose prior to the issuance and sale to the
Underwriters of the DECS and thereafter without the consent of any of the
Holders (i) to cure any ambiguity or to correct or supplement any provision
contained herein or therein which may be defective or inconsistent with any
other provision contained herein or therein; (ii) to change any provision hereof
or thereof as may be required by applicable law or the Commission or any
successor governmental agency exercising similar authority; or (iii) to make
such other provisions in regard to matters or questions arising hereunder or
thereunder as shall not materially adversely affect the interests of the Holders
(as determined in good faith by the Trustees, who may rely on an opinion of
counsel).

          (b)  This Trust Agreement may also be amended from time to time by the
Trustees (or the performance of any of the provisions of the Trust Agreement may
be waived) with the consent by the required vote of the Holders in accordance
with Section 8.1 hereof; provided that this Trust Agreement may not be amended
(i) without the consent by vote of the Holders of all DECS then outstanding, so
as to increase the number of DECS issuable hereunder above the number of DECS
specified in Section 2.5(c) hereof or such lesser number as may be outstanding
at any time during the term of this Trust Agreement, (ii) to reduce the interest
in the Trust represented by DECS without the consent of the Holders of such
DECS, (iii) if such amendment is prohibited by the Investment Company Act or
other applicable law, (iv) without

                                       19
<PAGE>

the consent by vote of the Holders of all DECS then outstanding, if such
amendment would effect a change in the voting requirements set forth in Section
8.1 hereof or this Section 8.4, or (v) without the consent by vote of the
Holders of the lesser of (x) 67% or more of the DECS represented at a special
meeting of Holders, if more than 50% of the DECS outstanding are represented at
such meeting, and (y) more than 50% of the DECS outstanding, if such amendment
would effect a change in Section 2.4 or 2.9 hereof.

          (c)  Promptly after the execution of any amendment, the Trustees shall
furnish written notification of the substance of such amendment to each Holder.

          (d)  Notwithstanding subsections (a) and (b) of this Section 8.4, no
amendment hereof shall permit the Trust, the Trustees, the Administrator, the
Paying Agent or the Custodian to take any action or direct or permit any Person
to take any action that (i) would vary the investment of Holders within the
meaning of Treasury Regulation Section 301.7701-4(c), or (ii) would or could
cause the Trust, or direct or permit any action to be taken that would or could
cause the Trust, not to be a "grantor trust" under the Code.

          SECTION 8.5 Accountants.
                      -----------

          (a)  The Trustees shall, in accordance with Section 30 of the
Investment Company Act, file annually with the Commission such information,
documents and reports as investment companies having securities registered on a
national securities exchange are required to file annually pursuant to Section
13(a)  of the Securities Exchange Act of 1934, as amended, and the rules and
regulations issued thereunder.  The Trustees shall transmit to the Holders, at
least semi-annually, the reports required by Section 30(d) of the Investment
Company Act and the rules and regulations thereunder, including, without
limitation, a balance sheet accompanied by a statement of the aggregate value of
investments on the date of such balance sheet, a list showing the amounts and
values of such investments owned on the date of such balance sheet, and a
statement of income for the period covered by the report.  Financial statements
contained in such annual reports shall be accompanied by a certificate of
independent public accounts based upon an audit not less in scope or procedures
than that which independent public accountants would ordinarily make for the
purpose of presenting comprehensive and dependable financial statements and
shall contain such information as the Commission may prescribe.  Each such
report shall state that such independent public accountants have verified
investments owned, either by actual examination or by receipt of a certificate
from the Custodian.

          (b)  The independent public accountants referred to in subsection (a)
above shall be selected at a meeting held within thirty days before or after the
beginning of the fiscal year by the vote, cast in person, of a majority of the
Trustees who are not "interested persons" as defined in the Investment Company
Act and such selection shall be submitted for ratification at the first meeting
of Holders to be held as set forth in Section 8.1 hereof, and thereafter as
required by the Investment Company Act and the rules and regulations thereunder.
The employment of any independent public accountant for the Trust shall be
conditioned upon the right of the Holders by a vote of the lesser of (i) 67% or
more of the DECS present at a special meeting of Holders, if Holders of more
than 50% of DECS outstanding are present or represented by proxy at such meeting
or (ii) more than 50% of the DECS outstanding to terminate such employment at
any time without penalty.

                                       20
<PAGE>

          (c)  The foregoing provisions of this Section 8.5 are in addition to
any applicable requirements of the Investment Company Act and the rules and
regulations thereunder.

          SECTION 8.6 Nature of Holder's Interest'.  Each Holder holds at any
                      ---------------------------
given time a beneficial interest in the Trust Estate, but does not have any
right to take title or possession of any portion of the Trust Estate.  Each
Holder expressly waives any right he may have under any rule of law, or the
provisions of any statute, or otherwise, to require the Trustees at any time to
account, in any manner other than as expressly provided in this Trust Agreement,
for the Shares, the Contract, the Treasury Securities or other assets or monies
from time to time received, held and applied by the Trustees hereunder.  No
Holder shall have any right except as provided herein to control or determine
the operation and management of the Trust or the obligations of the parties
hereto.  Nothing set forth herein or in the certificates representing DECS shall
be construed to constitute the Holders from time to time as partners or members
of an association.

          SECTION 8.7 Delaware Law to Govern.  This Trust Agreement is executed
                      ----------------------
and delivered in the State of Delaware, and all laws or rules of construction of
the State of Delaware shall govern the rights of the parties hereto and the
Holders and the construction, validity and effect of the provisions hereof.

          SECTION 8.8 Notices.  Any notice, demand, direction or instruction to
                      -------

substantially equivalent means as the Trustees may deem appropriate, or
delivered to such Holder at the address of such Holder appearing on the registry
of the Paying Agent.

          SECTION 8.9 Severability.  If any one or more of the covenants,
                      ------------
agreements, provisions or terms of this Trust Agreement shall be for any reason
whatsoever held invalid, then such covenants, agreements, provisions or terms
shall be deemed severable from the remaining covenants, agreements, provisions
and terms of this Trust Agreement and shall in no way affect the validity or
enforceability of the other provisions of this Trust Agreement or of the
Certificates, or the rights of the Holders thereof.

          SECTION 8.10 Counterparts.  This Trust Agreement may be executed in
                       ------------
several counterparts, each of which shall be an original and all of which shall
constitute one and the same instrument.

          SECTION 8.11 Successors and Assigns.  Whenever in this Trust Agreement
                       ----------------------
any of the parties hereto is named or referred to, the successors and assigns of
such party shall be deemed to be included, and all covenants and agreements in
this Trust Agreement by the Sponsor

                                       21

and Trustees shall bind and inure to the benefit of their respective successors
and assigns, whether or not so expressed.

Act by the holders of the Securities and the Trustees have been obtained and are

Fundamental Agreements will be in full force and effect and the Trust will not
be in default thereunder and, to the knowledge of the Trust, no event will have

the assets of the Trust, and the issuance of such DECS will not be subject to
any preemptive or similar rights.  No person has rights to the registration of
any securities because of the filing of the Trust Registration Statement, and no

the various states in connection with the offer and sale of the DECS.

          (r) There are no material restrictions, limitations or regulations

no such proceedings are threatened or contemplated by governmental authorities
or threatened by others.

          (u) The statement of assets, liabilities and capital included in the

          2.  Representations and Warranties of the Company.  The Company
              ---------------------------------------------
represents and warrants to, and agrees with, each Underwriter as set forth below
in this Section 2.

          (a) The Company meets the requirements for use of Form S-3 under the
Act, meets the requirements for an offering of securities on a delayed basis
under Rule 415 and has prepared and filed with the Commission a registration
statement (file number 333- 83395) on Form S-3, including a related preliminary
prospectus and a related basic prospectus, for the registration under the Act of
the Shares in connection with the offering and sale of the DECS.  The Company
may have filed one or more amendments thereto, including the related preliminary
prospectuses and the related basic prospectus, each of which has previously been
furnished to you.  The Company will next file with the Commission one of the
following:  either (1) prior to the Company Effective Date of such registration
statement, a further amendment to such registration statement, (including the
final forms of such prospectuses), (2) after the Company Effective Date of such
registration statement, such final prospectuses in accordance with Rules 430A
and 424(b), or (3) a final prospectus in accordance with Rules 415 and 424(b).
In the case of clause (2), the Company has included in such registration
statement, as amended at the Company Effective Date, all information (other than
Rule 430A Information) required by the Act and the rules thereunder to be
included in such registration statement and the Company Prospectus with respect
to the Shares and the offering thereof.  As filed, such amendment and form of
final prospectuses, or such final prospectuses, shall contain all Rule 430A
Information, together with all other such required information with respect to
the Shares and the offering thereof and, except to the extent the
Representatives shall agree in writing to a modification, shall be in all
substantive respects in the form furnished to you prior to the Execution Time
or, to the extent not completed at the Execution Time, shall contain only such
specific additional information and other changes (beyond that contained in the
latest Preliminary Company Prospectus) as the Company has advised you, prior to
the Execution Time, will be included or made therein.  If the Company
Registration Statement contains the undertaking specified by Regulation S-K Item
512(a), the Company Registration Statement, at the Execution Time, meets the
requirements set forth in Rule 415(a)(1)(x).

          (b) On the Company Effective Date, the Company Registration Statement
did or will, and when the Company Prospectus is first filed (if required) in
accordance with Rule 424(b) and on the Closing Date (as defined herein) and on
any Settlement Date, the Company Prospectus (and any supplements thereto) will,
comply in all material respects with the applicable requirements of the Act and
the respective rules thereunder; on the Company Effective Date and at the
Execution Time, the Company Registration Statement did not or will not contain
any untrue statement of a material fact or omit to state any material fact
required to be stated therein or necessary in order to make the statements
therein not misleading; and, on the Company Effective Date, the Company
Prospectus, if not filed pursuant to Rule 424(b), did not or will not, and on
the date of any filing pursuant to Rule 424(b) and on the Closing Date and any
Settlement Date, the Company Prospectus (together with any supplement thereto)
will not, include any untrue statement of a material fact or omit to state a
material fact necessary in order to make the statements therein, in the light of
the circumstances under which they were made, not misleading; provided, however,
                                                              --------  -------
that the Company makes no

                                       6
<PAGE>

representations or warranties as to the information contained in or omitted from
the Company Registration Statement, or the Company Prospectus (or any supplement
thereto) in reliance upon and in conformity with information furnished herein or
in writing to the Company by or on behalf of any Underwriter through the
Representatives specifically for inclusion in the Company Registration Statement
or the Company Prospectus (or any supplement thereto).

          (c) No stop order suspending the effectiveness of the Company
Registration Statement is in effect, no order preventing or suspending the use
of any Preliminary Company Prospectus has been issued by the Commission, and no
proceedings for any such purpose are pending before or threatened by the
Commission.  Each document incorporated by reference in the Company Registration
Statement or the Company Prospectus, when they were filed or are filed with the
Commission, conformed or will conform in all material respects to the
requirements of the Exchange Act and the rules and regulations of the Commission
thereunder, and none of such documents contained or will contain an untrue
statement of a material fact or omitted or will omit to state a material fact
required to be stated therein or necessary to make the statements therein not
misleading.

          (d) The Company is not and, after giving effect to the sale of the
sale of the Shares, will not be an "investment company" as defined in the
Investment Company Act.

          (e) Neither the Company nor any of its subsidiaries has taken and none
of such entities will take, directly or indirectly, any action designed to or
which has constituted or which might reasonably be expected to cause or result,
under the Exchange Act or otherwise, in the stabilization or manipulation of the
price of any security of the Company to facilitate the sale or resale of the
DECS.

          (f) Neither the Company nor any of its subsidiaries has sustained
since the date of the latest audited financial statements included in the
Company Prospectus any material loss or interference with its business from
fire, explosion, flood or other calamity, whether or not covered by insurance,
or from any labor dispute or court or governmental action, order or decree,
otherwise than as set forth or contemplated in the Company Prospectus; and,
since the respective dates as of which information is given in the Company
Registration Statement and the Company Prospectus, there has not been any change
in the capital stock or long-term debt of the Company or any of its subsidiaries
or any material adverse change, or any development involving a prospective
material adverse change, except such as are described in the Company Prospectus
or such as would not be reasonably expected, in the aggregate, to result in a
material adverse effect on the condition (financial or other), business,
prospects, properties or results of operations of the Company and its
"significant subsidiaries" as defined in Rule 405 of the rules and regulations
of the Commission promulgated under the Act, taken as a whole ("Material Adverse
Effect");

          (g) The Company and its subsidiaries have good and marketable title to
all real property and good and marketable title to all personal property owned
by them, in each case free and clear of all liens, encumbrances and defects
except such as are described in the Company Prospectus; and any real property
and buildings held under lease by the Company and its subsidiaries are held by
them under valid, subsisting and enforceable leases with such exceptions as
would not be reasonably expected, in the aggregate, to result in a Material
Adverse Effect;

registered and qualified to conduct its business and is in good standing in each
jurisdiction or place where the nature of its properties or the conduct of its
business requires such registration or qualification, except where the failure
so to register or qualify or to be in good standing would not have a Material
Adverse Effect; and each subsidiary of the Company has been duly incorporated

Company, free and clear of all liens, encumbrances, equities or claims, except

          (k) The consummation of the transactions herein contemplated will not
conflict with or result in a breach or violation of any of the terms or
provisions of, or (with the giving of notice or the lapse of time or both)

<PAGE>

(2) as may have already been obtained or made and (3) the failure to obtain or
make would not, individually or in the aggregate, have a Material Adverse
Effect;

          (l) Neither the Company nor any of its subsidiaries (A) is in
violation of its Organizational Documents, (B) is in default in any material
respect, and no event has occurred which, with notice or lapse of time or both,
would constitute such a default, in the due performance or observance of any
term, covenant or condition contained in any material indenture, mortgage, deed
of trust, loan agreement or other agreement or instrument to which it is a party
or by which it is bound or to which any of its properties or assets is subject
or (C) is in violation in any material respect of any law, ordinance,

          (m) The statements set forth in the Company Prospectus under the
caption "Description of Capital Stock", insofar as they purport to constitute a
summary of the terms of the capital stock of the Company, under the caption
"Certain US Income Tax Considerations for Non-U.S. Holders" and under the
caption "Plan of Distribution", insofar as they purport to describe the
provisions of the laws and documents referred to therein, are accurate, complete
and fair;

          (n) Other than as set forth in the Company Prospectus, there are no
legal or governmental proceedings pending to which the Company or any of its
subsidiaries is a party or of which any property of the Company or any of its
subsidiaries is the subject which, if determined adversely to the Company or any
of its subsidiaries, would individually or in the aggregate have a Material
Adverse Effect; and, to the best of the Company's knowledge, no such proceedings
are threatened or contemplated by governmental authorities or threatened by
others;

          (o) KPMG Peat Marwick LLP, who have certified certain financial
statements of the Company and its subsidiaries and of certain other business
operations to be acquired by the Company and its subsidiaries, are independent
public accountants as required by the Act and the rules and regulations of the
Commission thereunder;

          (p) The Company has reviewed its operations and that of its
subsidiaries and is in the process of reviewing any third parties with which the
Company or any of its subsidiaries has a material relationship to evaluate the
extent to which the business or operations of the Company or any of its
subsidiaries will be affected by the Year 2000 Problem.  As a result of such
review, the Company has no reason to believe, and does not believe, that the
Year 2000 Problem will have a Material Adverse Effect.  The "Year 2000 Problem"
as used herein means any significant risk that computer hardware or software
used in the receipt, transmission, processing, manipulation, storage, retrieval,
retransmission or other utilization of data or in the operation of mechanical or
electrical systems of any kind will not, in the case of dates or time periods
occurring after December 31, 1999, function at least as effectively as in the
case of dates or time periods occurring prior to January 1, 2000;

                                       9
<PAGE>

          (q) This Agreement has been duly authorized, executed and delivered by
the Company and, assuming due authorization, execution and delivery by the
Underwriters, constitutes the valid and binding agreement of the Company,
enforceable against the Company in accordance with its terms (subject to
applicable bankruptcy, insolvency, reorganization, moratorium, fraudulent
transfer and other similar laws affecting creditors' rights generally from time
to time in effect and to general principles of equity, including, without
limitation, concepts of materiality, reasonableness, good faith and fair
dealing, regardless of whether in a proceeding in equity or at law);

          (r) The consolidated historical and pro forma financial statements,
together with the related notes thereto filed as part of the Company
Registration Statement or included in the Company Prospectus comply as to form
in all material respects with the requirements of Regulation S-X under the Act
applicable to registration statements on Form S-3 under the Act.  Such
historical financial statements fairly present the financial position of the
Company at the respective dates indicated and the results of operations and cash
flows for the respective periods indicated, in each case in accordance with
generally accepted accounting principles ("GAAP") consistently applied
throughout such periods.  Such pro forma financial statements have been prepared
on a basis consistent with such historical statements, except for the pro forma
adjustments specified therein, and give effect to assumptions made on a
reasonable basis and in good faith and present fairly the pro forma position,
results of operations and the other information purported to be shown therein at
the respective dates or the respective periods therein specified.  The other
financial and statistical information and data filed as part of the Company
Registration Statement or included in the Company Prospectus, historical and pro
forma, are, in all material respects, fairly presented and prepared on a basis
consistent with such financial statements and the books and records of the
Company;

          (s) The Company and each of the Significant Subsidiaries has such
permits, licenses, franchises, certificates of need and other approvals or
authorizations of any governmental or regulatory authority ("Permits"),
including, without limitation, any permits required by the Federal
Communications Commission ("FCC"), the Federal Aviation Administration ("FAA")
or the Office of Telecommunications ("OFTEL"), as are necessary under applicable
law to own their respective properties and to conduct their respective
businesses in the manner described in the Company Prospectus, except to the
extent that the failure to have such Permits would not have a Material Adverse
Effect.  The Company and the Significant Subsidiaries have fulfilled and
performed, in all material respects, all their respective obligations with
respect to the Permits, and no event has occurred which allows, or after notice
or lapse of time would allow, revocation or termination thereof or results in
any other material impairment of the rights of the holder of any such Permit,
subject in each case to such qualification as may be set forth in the Company
Prospectus and except to the extent that any such revocation or termination
would not have a Material Adverse Effect.  Except as described in the Company
Prospectus, none of the Permits contains any restriction that has not previously
been satisfied and that is materially burdensome to the Company or any of the
Significant Subsidiaries;

          (t) For each existing tower of the Company not yet registered with the
FCC where registration will be required, the FCC's grant of an application for
registration of such tower will not have a significant environmental effect as
defined under Section 1.1307(a) of the FCC's rules;

                                       10
<PAGE>

          (u) The consummation of the transactions contemplated by this
Agreement shall not cause any third party to have any rights of first refusal
with respect to the acquisition of towers under any agreement filed as an
exhibit to, or incorporated by reference in, the Company Registration Statement
(the "Material Agreements") that has not already been described in the Company
Prospectus as to which the Company and any of the Significant Subsidiaries or
any of their property or assets may be subject;

          (v) The Company and each of the Significant Subsidiaries owns or

the Company nor any of the Significant Subsidiaries is aware of any claim to the
contrary or any challenge by any other person to the rights of the Company or
any of the Significant Subsidiaries with respect to such rights that, if
determined adversely to the Company or any such Significant Subsidiary, would in
the aggregate have a Material Adverse Effect;

          (w) The descriptions in the Company Prospectus of all agreements,
contracts, indentures, leases or other instruments are accurate in all material
respects and fairly present the information purported to be described therein;

          (x) Neither the Company nor any of its subsidiaries is involved in any
strike, job action or labor dispute with any group of employees, and, to the
knowledge of the Company and the Subsidiaries, no such action or dispute is
threatened;

          (y) The Company and each of its subsidiaries are in compliance in all
material respects with all presently applicable provisions of the Employee
Retirement Income Security Act of 1974, as amended, including the regulations

respect to termination of, or withdrawal from, any "pension plan" or (ii)
Sections 412 or 4971 of the Internal Revenue Code of 1986, as amended, including
the regulations and published interpretations thereunder (the "Code"); and each
"pension plan" for which the Company would have any liability that is intended
to be qualified under Section 401(a) of the Code is so qualified in all material
respects and nothing has occurred, whether by action or by failure to act, which
would cause the loss of such qualification;

state and local income and franchise tax returns required to be filed through
the date hereof and have paid all taxes due thereon, and no tax deficiency has

which, if determined adversely to the Company or any of its subsidiaries, would
have a Material Adverse Effect;

Prospectus through the date hereof, and except as may otherwise be disclosed in

          3.  Representations and Warranties of the Sellers.  Each of the
              ---------------------------------------------
Sellers, severally and jointly, represents and warrants to, and agrees with,
each Underwriter, the Company and the Trust that:

          (a) Each of the Sellers is validly existing as a corporation or
limited liability company, as the case may be, in good standing under the laws
of the State of Delaware, with full power and authority to own its property, and
does not conduct any business in any jurisdiction, own any material property
other than Shares or have any subsidiaries.

          (c) Each Seller has full right, power and authority to enter into and
perform its obligations under this Agreement, the Contract and Collateral
Agreement to which such Seller is a party and the letter agreement among each of
the Sellers, Salomon Smith Barney and Goldman Sachs relating to expenses of the
Trust (the "Reimbursement Agreement").
            -----------------------

          (d) This Agreement has been duly authorized, executed and delivered by
each Seller.  Each Contract and Collateral Agreement to which each Seller is a
party and the Reimbursement Agreement have been duly authorized, executed and
delivered by such Seller and, assuming due authorization, execution and delivery
by the other parties thereto, is a valid and binding agreement of such Seller,
enforceable against such Seller in accordance with its terms.

          (e) The execution and delivery by each Seller of this Agreement, each
Contract and Collateral Agreement to which such Seller is a party and the
Reimbursement Agreement, the performance by such Seller of its obligations
hereunder and thereunder and the consummation of the transactions herein and
therein contemplated do not and will not, whether with or without the giving of
notice or passage of time or both, conflict with, result in a breach or
violation of or imposition of any lien (other than pursuant to each Collateral
Agreement to which such Seller is a party), charge or encumbrance upon any
property or assets of such Seller pursuant to (i) the Organizational Documents
of such Seller, (ii) the terms of any indenture, contract, lease, mortgage, deed
of trust, note agreement, loan agreement or other agreement, obligation,
condition, covenant or instrument to which such Seller is a party or bound or to
which its property is subject, or (iii) any statute, law, rule, regulation,
judgment, order or decree applicable to such Seller of any court, regulatory
body, administrative agency, governmental body, arbitrator or other authority
having jurisdiction over such Seller or any of its properties. Amounts received
by each of the Sellers, if any, at the Closing Date and, if any Option DECS are
purchased, at the time of delivery thereof pursuant to Section 4(b), pursuant to
such Seller's Contract will not be used by such Seller for the purpose, whether
immediate, incidental or ultimate, of buying or carrying a margin stock, as such
terms are defined in Regulation G promulgated by the Board of Governors of the
Federal Reserve System.

          (f) Each of the Sellers is not and, after giving effect to the
transactions contemplated in each Contract and Collateral Agreement and the
offering and sale of the DECS contemplated by this Agreement, will not be an
"investment company" or an entity "controlled" by an "investment company" as
such terms are defined in the Investment Company Act.

          (g) Each of the Sellers is the sole registered owner of and has, and
on the Closing Date (and, if any Option DECS are purchased, at the time of
delivery thereof pursuant to Section 4(b)) will have, good and valid title to
the Shares to be pledged and assigned by it under its Collateral Agreement, free
and clear of any security interests, claims, liens, equities and other
encumbrances, except for those created pursuant to its Collateral Agreement; and
such Seller has the full right,

                                       13
<PAGE>

power and authority, and all authorization and approval required by law to
pledge and assign the Shares to be pledged and assigned by such Seller pursuant
to its Collateral Agreement.

          (h) Title to any Shares to be delivered by a Seller pursuant to such
Seller's Contract on the Exchange Date, assuming payment of the consideration
due pursuant to such Seller's Contract on the Closing Date, will pass to the
Trust free and clear of any security interests, claims, liens, equities and
other encumbrances.  The sale, transfer and delivery of any Shares to be
delivered by a Seller pursuant to such Seller's Contract is not, and at the time
of delivery of such Shares will not be, subject to any right of first refusal or
similar rights of any person pursuant to any contract to which such Seller or
any shareholder of such Seller is a party or by which any of them is bound.

          (i) Each of the Sellers hereby repeats and confirms as if set forth in
full herein each of the representations, warranties, guarantees and agreements
made by such Seller in each Contract and Collateral Agreement to which such
Seller is a party and agrees that the representations, warranties, guarantees
and agreements therein and herein are made hereby for the benefit of, and may be
relied upon by, (i) the Underwriters and Cleary, Gottlieb, Steen & Hamilton,
counsel to the Underwriters and (ii) the Company and Cravath, Swaine & Moore,
counsel to the Company.

          (j) None of the Sellers has taken or will take, directly or
indirectly, any action which is designed to or which has constituted or which
might reasonably be expected to cause or result, under the Exchange Act or
otherwise, in stabilization or manipulation of the price of any security of the
Company to facilitate the sale or resale of the Shares or the DECS.

          (k) Each Seller is familiar with the Company Registration Statement
and the Company Prospectus and verifies that the information set forth therein
respecting it is true and complete.

          (l) No consent, approval, license, authorization, order or validation
of, and no filing, recording, or registration with, any court or governmental
authority, agency or body is required for the compliance by each Seller with all
of the provisions of this Agreement, each Contract and Collateral Agreement to
which such Seller is a party and the Reimbursement Agreement, except such as
have been obtained under the Act and such as may be required under the blue sky
laws in connection with the purchase and distribution of the DECS by the
Underwriters and the distribution of the Shares pursuant to the terms of the
DECS in the manner contemplated in this Agreement and in the Trust Prospectus
and the Company Prospectus.

          (m) Certificates in negotiable form for each Seller's Shares have been
placed in custody, for delivery pursuant to the terms of such Seller's Contract
and Collateral Agreement, under a Custody Agreement duly authorized, executed
and delivered by such Seller, in the form heretofore furnished to you (the

"Custody Agreement") with the Bank of New York, as Custodian (the "Custodian");
- ------------------                                                 ---------
the Shares represented by the certificates so held in custody for each Seller
are subject to the interests of the Trust pursuant to such Seller's Contract and
Collateral Agreement; the arrangements for custody and delivery of such
certificates, made by such Seller pursuant to such Seller's Contract and
Collateral Agreement and the Custody Agreement, are not subject to termination
by any acts of such Seller, or by operation of law, whether by the death or
incapacity of such Seller or the occurrence of any other event; and if any such
death, incapacity or any other such event shall occur before the delivery of
such Shares pursuant to such Seller's Contract and Collateral Agreement,
certificates for the Shares will be delivered by the Custodian in accordance
with the terms and conditions of such Seller's Contract and Collateral Agreement
and the Custody Agreement

                                       14
<PAGE>

as if such death, incapacity or other event had not occurred, regardless of
whether or not the Custodian shall have received notice of such death,
incapacity or other event.

          (n) Each of the Sellers has no reason to believe that the
representations and warranties of the Company contained in Section 2 hereof are
not true and correct, is familiar with the Company Registration Statement and
has no knowledge of any material fact, condition or information not disclosed in
the Company Prospectus or any supplement thereto which has adversely affected or
may adversely affect the business of the Company or any of its subsidiaries; and
the sale of Shares by such Seller pursuant hereto is not prompted by any
information  concerning the Company or any of its subsidiaries which is not set
forth in the Company Prospectus or any supplement thereto.

          Any certificate signed by or on behalf of any Seller, and delivered to
the Representatives or counsel for the Underwriters in connection with the
offering of the Securities shall be deemed a representation and warranty by such
Seller as to matters covered thereby, to each Underwriter.

          4.  Purchase and Sale.
              -----------------

          (a) Subject to the terms and conditions and in reliance upon the
representations and warranties herein set forth, the Trust agrees to sell to
each Underwriter, and each Underwriter agrees, severally and not jointly, to
purchase from the Trust, at a purchase price of $** per DECS, the amount of the
Underwritten DECS set forth opposite such Underwriter's name in Schedule I
hereto.

          (b) Subject to the terms and conditions and in reliance upon the
representations and warranties herein set forth, the Trust hereby grants an
option to the several Underwriters to purchase, severally and not jointly, up to
645,000 Option DECS at the same purchase price per DECS as the Underwriters
shall pay for the Underwritten DECS.  The option may be exercised only to cover
over-allotments in the sale of the Underwritten DECS by the Underwriters.  The
option may be exercised in whole or in part at any time (but not more than once)
on or before the 30th day after the date of the Trust Prospectus upon written or
facsimile notice by the Representatives to the Trust setting forth the number of
Option DECS as to which the several Underwriters are exercising the option and
the Settlement Date.  Delivery of certificates for the Option DECS by the Trust,
and payment therefor to the Trust, shall be made as provided in Section 5
hereof.  The number of Option DECS to be purchased by each Underwriter shall be
the same percentage of the total number of Option DECS to be purchased by the
several Underwriters as such Underwriter is purchasing of the Underwritten DECS,
subject to such adjustments as you in your absolute discretion shall make to
eliminate any fractional DECS.

          (c) As compensation to the Underwriters for their commitment
hereunder, and in view of the fact that the proceeds of the sale of the DECS
will be used by the Trust as specified in the Contracts, the Sellers agree,
severally and jointly, to pay to Salomon Smith Barney, at the time of each
delivery of DECS pursuant to Section 5, an amount equal to $0. ** per DECS being
delivered at such time, plus $0. ** per DECS for each Subscription DECS owned by
Salomon Smith Barney after giving effect to the subdivision of the Subscription
DECS provided for in the Subscription Agreement.

          5.  Delivery and Payment.  Delivery of and payment for the
              --------------------
Underwritten DECS and the Option DECS (if the option provided for in Section
4(b) hereof shall have been exercised on

                                       15
<PAGE>

or before the first Business Day prior to the Closing Date) shall be made at
10:00 A.M., New York City time, on **, 1999, or at such time on such later date
not later than five Business Days after the foregoing date as the
Representatives shall designate, which date and time may be postponed by
agreement among the Representatives, the Trust and the Sellers or as provided in
Section 14 hereof (such date and time of delivery and payment for the DECS being
herein called the "Closing Date"). Delivery of the DECS shall be made to the
                   ------------
Representatives for the respective accounts of the several Underwriters against
payment by the several Underwriters through the Representatives of the purchase
price thereof to or upon the order of the Trust by wire transfer payable in
immediately available same-day funds to an account specified by the Trust in
writing at least two Business Days in advance of the Closing Date. Delivery of
the DECS shall be made through the facilities of the Depository Trust Company
unless the Representatives shall otherwise instruct.

          The Trust agrees to have the DECS available for inspection and
checking by the Representatives in New York, New York, not later than 1:00 P.M.
on the Business Day prior to the Closing Date.

          If the option provided for in Section 4(b) hereof is exercised after
the first Business Day prior to the Closing Date, the Trust will deliver the
Option DECS (at the expense of the Trust) to the Representatives on the date
specified by the Representatives (which shall be within three Business Days
after exercise of said option) for the respective accounts of the several
Underwriters, against payment by the several Underwriters through the
Representatives of the purchase price thereof to or upon the order of the Trust
by wire transfer payable in immediately available same-day funds to an account
specified by the Trust in writing at least two Business Days in advance of such
Settlement Date.  If settlement for the Option DECS occurs after the Closing
Date, the Trust, the Company and the Sellers will deliver to the Representatives
on the Settlement Date for the Option DECS, and the obligation of the
Underwriters to purchase the Option DECS shall be conditioned upon receipt of,
supplemental opinions, certificates and letters confirming as of such date the
opinions, certificates and letters delivered on the Closing Date pursuant to
Section 10 hereof.

          6.  Offering by the Underwriters.  It is understood that the several
              ----------------------------
Underwriters propose to offer the DECS for sale to the public as set forth in
the Trust Prospectus.

          7.  Agreements of the Trust.  The Trust agrees with the several
              -----------------------
Underwriters that:

          (a) The Trust will use its best efforts to cause the Trust
     Registration Statement, if not effective at the Execution Time, and any
     amendment thereof, to become effective.  Prior to the termination of the
     offering of the DECS, the Trust will not file any amendment of the Trust
     Registration Statement or supplement to the Trust Prospectus or any Rule
     462(b) Trust Registration Statement unless the Trust has furnished you a
     copy for your review prior to filing and will not file any such proposed
     amendment or supplement to which you object.  Subject to the foregoing
     sentence, if the Trust Registration Statement has become or becomes
     effective pursuant to Rule 430A, or filing of the Trust Prospectus is
     otherwise required under Rule 424(b), the Trust will cause the Trust
     Prospectus, properly completed, and any supplement thereto to be filed with
     the Commission pursuant to the applicable paragraph of Rule 424(b) within
     the time period prescribed and will provide evidence satisfactory to the
     Representatives of such timely filing.  The Trust will promptly advise the
     Representatives (1) when the Trust Registration Statement, if not effective
     at the Execution Time, shall have become effective, (2) when the Trust
     Prospectus, and any supplement thereto, shall have been

                                       16
<PAGE>

     filed (if required) with the Commission pursuant to Rule 424(b) or when any
     Rule 462(b) Trust Registration Statement shall have been filed with the
     Commission, (3) when, prior to termination of the offering of the DECS, any
     amendment to the Trust Registration Statement or any Rule 462(b) Trust
     Registration Statement, shall have been filed or become effective, (4) of
     any request by the Commission or its staff for any amendment of the Trust
     Registration Statement, or any Rule 462(b) Trust Registration Statement, or
     for any supplement to the Trust Prospectus or for any additional
     information, (5) of the issuance by the Commission of any stop order
     suspending the effectiveness of the Trust Registration Statement or the
     institution or threatening of any proceeding for that purpose and (6) of
     the receipt by the Trust of any notification with respect to the suspension
     of the qualification of the DECS for sale in any jurisdiction or the
     institution or threatening of any proceeding for such purpose. The Trust
     will use its best efforts to prevent the issuance of any such stop order or
     the suspension of any such qualification and, if issued, to obtain as soon
     as possible the withdrawal thereof.

          (b) If, at any time when a prospectus relating to the DECS is required
     to be delivered under the Act, any event occurs as a result of which the
     Trust Prospectus as then supplemented would include any untrue statement of
     a material fact or omit to state any material fact necessary to make the
     statements therein in the light of the circumstances under which they were
     made not misleading, or if it shall be necessary to amend the Trust
     Registration Statement or supplement the Trust Prospectus to comply with
     the Act or the Exchange Act or the respective rules thereunder, the Trust
     promptly will (1) notify the Representatives of any such event, (2) prepare
     and file with the Commission, subject to the second sentence of paragraph
     (a) of this Section 7, an amendment or supplement which will correct such
     statement or omission or effect such compliance and (3) supply any
     supplemental Trust Prospectus to you in such quantities as you may
     reasonably request.

          (c) The Trust will furnish to the Representatives and counsel for the
     Underwriters, without charge, signed copies of the Trust Registration
     Statement (including exhibits thereto) and to each other Underwriter a copy
     of the Trust Registration Statement (without exhibits thereto).  The Trust
     will furnish to the Representatives and counsel for the Underwriters,
     without charge, copies of the Trust Registration Statement (including
     exhibits thereto).  The Trust will furnish to the Underwriters not later
     than (i) 6:00 P.M., New York City time, on the date of determination of the
     public offering price of the DECS, if such determination occurred at or
     prior to 12:00 noon, New York City time, on such date or (ii) 6:00 P.M.,
     New York City time, on the Business Day following the date on which the
     public offering price was determined, if such determination occurred after
     12:00 noon, New York City time, on such date, as many copies of each
     Preliminary Trust Prospectus, the Trust Prospectus and any supplement
     thereto as the Representatives may reasonably request; further, so long as
     delivery of a prospectus by an Underwriter or any dealer may be required by
     the Act, as many copies of each Preliminary Trust Prospectus and the Trust
     Prospectus and any supplement thereto as the Representatives may reasonably
     request.

          (d) The Trust will arrange, if necessary, for the qualification of the
     DECS and the Shares for sale under the laws of such jurisdictions as the
     Representatives may designate, will maintain such qualifications in effect
     so long as required for the distribution of the DECS and will pay any fee
     of the National Association of Securities Dealers, Inc. (the "NASD"), in
                                                                   ----
     connection with its review, if any, of the Trust Registration Statement and
     the offering of the DECS.

          8.  Agreements of the Company.  The Company agrees with the several
              -------------------------
Underwriters that:

          (a) The Company will use its best efforts to cause the Company
     Registration Statement, if not effective at the Execution Time, and any
     amendment thereof, to become effective.  Prior to the termination of the
     offering of the DECS, the Company will not file any amendment of the
     Company Registration Statement or supplement to the Company Prospectus or
     any Rule 462(b) Company Registration Statement unless the Company has
     furnished to you a copy for your review prior to filing and will not file
     any such proposed amendment or supplement to which you reasonably object.
     Subject to the foregoing sentence, if the Company Registration Statement
     has become or becomes effective pursuant to Rule 430A, or filing of the
     Company Prospectus is otherwise required under Rule 424(b), the Company
     will cause the Company Prospectus, properly completed, and any supplement
     thereto to be filed with the Commission pursuant to the applicable
     paragraph of Rule 424(b) within the time period prescribed and will provide
     evidence satisfactory to the Representatives of such timely filing.  The
     Company will promptly advise the Representatives (1) when the Company
     Registration Statement, if not effective at the Execution Time, shall have
     become effective, (2) when the Company Prospectus, and any supplement
     thereto, shall have been filed (if required) with the Commission pursuant
     to Rule 424(b) or when any Rule 462(b) Company Registration Statement shall
     have been filed with the Commission, (3) when, prior to termination of the
     offering of the DECS, any amendment to the Company Registration Statement
     shall have been filed or become effective, (4) of any request by the
     Commission or its staff for any amendment of the Company Registration
     Statement, or any Rule 462(b) Company Registration Statement, or for any
     supplement to the Company Prospectus or for any additional information, (5)
     of the issuance by the Commission of any stop order suspending the
     effectiveness of the Company Registration Statement or the institution or
     threatening of any proceeding for that purpose and (6) of the receipt by
     the Company of any notification with respect to the suspension of the
     qualification of the Shares for sale in any jurisdiction or the institution
     or threatening of any proceeding for such purpose.  The Company will use
     its best efforts to prevent the issuance of any such stop order or the
     suspension of any such qualification and, if issued, to obtain as soon as
     possible the withdrawal thereof.

          (b) If, at any time when a prospectus relating to the Shares is
     required to be delivered under the Act (including in respect of the
     offering and sale of the DECS), any event occurs as a result of which the
     Company Prospectus as then supplemented would include any untrue statement
     of a material fact or omit to state any material fact necessary to make the
     statements therein in the light of the circumstances under which they were
     made not misleading, or if it shall be necessary to amend the Company
     Registration Statement or supplement the Company Prospectus to comply with
     the Act or the Exchange Act or the respective rules thereunder, the Company
     promptly will (1) notify the Representatives of such event, (2) prepare and
     file with the Commission, subject to the second sentence of paragraph (a)
     of this Section 8, an amendment or supplement which will correct such
     statement or omission or effect such compliance and (3) supply any
     supplemented Company Prospectus to you in such quantities as you may
     reasonably request.

          (c) As soon as practicable, the Company will make generally available
     to its security holders and to the Representatives an earnings statement or
     statements of the

                                       18

     Company and its subsidiaries which will satisfy the provisions of Section
     11(a) of the Act and Rule 158 under the Act.

          (d) The Company will furnish to the Representatives and counsel for
     the Underwriters, without charge, signed copies of the Company Registration
     Statement (including exhibits thereto) and to each other Underwriter a copy
     of the Company Registration Statement (without exhibits thereto).  The
     Company will furnish to the Underwriters not later than (A) 6:00 P.M., New

     supplement thereto as the Representatives may reasonably request.  The
     Company will pay the expenses of printing or other production of the
     Company Registration Statement, each Preliminary Company Prospectus and the
     Company Prospectus.

          (e) The Company will cooperate with the Trust for purposes of the
     qualification of the DECS and the Shares for sale under the laws of such
     jurisdictions as the Representatives may designate, will maintain such
     qualifications in effect so long as required for the distribution of the
     DECS or the Shares and will pay any fee of the NASD in connection with its
     review, if any, of the Company Registration Statement and the offering of
     the Shares in connection with the offering of the DECS; provided that in no
     event shall the Company be obligated to qualify to do business in any
     jurisdiction where it is not now so qualified or to take any action that
     would subject it to service of process in suits, in each case, other than
     those arising out of the offering or sale of the DECS or the offering and
     sale of the Shares in connection with the offering of the DECS in any
     jurisdiction where it is not now so subject.

          (f) The Company will not, without the prior written consent of Salomon

     purchase, purchase any option or contract to sell, grant any option, right
     or warrant to purchase or otherwise transfer or dispose of, directly or
     indirectly, or announce the offering of any shares of any class of common
     stock of the Company or any securities convertible into or exercisable or
     exchangeable for shares of any class of common stock of the Company
     (whether such shares or any such securities are now owned or hereafter
     acquired) or (ii) enter into any swap or other arrangement that transfers
     to another, in whole or in part, any of the economic consequences of
     ownership of shares of any class of the common stock of the Company,
     whether any such transaction described in clause (i) or (ii) above is to be
     settled by delivery of shares of any class of common stock of the Company
     or such other securities, in cash or otherwise; provided, however, that the
     Company may issue, or grant options for, shares of any class of common
     stock of the Company pursuant to any stock plan for employees or directors,
     or any employee benefit plan, of the Company in effect at the Execution
     Time, or pursuant to any stock options outstanding at the Execution Time.

     the DECS or the Shares.

          9.  Agreements of the Sellers.  Each Seller agrees with each of the
              -------------------------
Underwriters that:

     purchase, purchase any option or contract to sell, grant any option, right
     or warrant to purchase or otherwise transfer or dispose of, directly or
     indirectly, or announce the offering of any shares of any class of common
     stock of the Company or any securities convertible into or exercisable or
     exchangeable for shares of any class of common stock of the Company
     (whether such shares or any such securities are now owned or hereafter
     acquired) or (ii) enter into any swap or other arrangement that transfers
     to another, in whole or in part, any of the economic consequences of
     ownership of Shares of any class of the common stock of the Company,
     whether any such transaction described in clause (i) or (ii) above is to be
     settled by delivery of Shares of any class of common stock of the Company
     or such other securities, in cash or otherwise; provided, however, that the
     Seller may engage in any of the transactions described in clause (i) or

     delivery of Shares pursuant to the terms of the DECS.

          (b) No Seller will take any action designed to or which has
     constituted or which might reasonably be expected to cause or result, under
     the Exchange Act or otherwise, in stabilization or manipulation of the
     price of any security of the Company to facilitate the sale or resale of
     the DECS or the Shares, it being understood that this sentence shall not
     apply to any share repurchase program conducted by the Company in
     compliance with the Exchange Act and all other applicable law.

          (c) Each Seller will advise you promptly, and if requested by you,
     will confirm such advice in writing, so long as delivery of a prospectus
     relating to the Shares (including with respect to the offering and sale of
     the DECS) by an underwriter or dealer may be required under the Act, of any
     change in the information in the Company Registration Statement or the
     Company Prospectus relating to such Seller.

                                       22
<PAGE>

          Company with the provisions hereof (i) requires any consent, approval,
          authorization or other order of, or registration or filing with, any
          court, regulatory body, administrative agency or other governmental
          body, agency or official, or conflicts or will conflict with or
          constitutes or will constitute a breach of, or a default under, the
          Organizational Documents of the Company or the Significant
          Subsidiaries or (ii) conflicts or will conflict with or constitutes or
          will constitute a breach of, or a default under, any Material
          Agreement or violates or will violate any law, rule or regulation of
          the United States, or the State of New York or the General Corporation
          Law of the State of Delaware, or, to such counsel's knowledge, any
          order or decree of any court or government agency or instrumentality
          or will result in the creation or imposition of any lien, mortgage,
          security interest, pledge, charge, or encumbrance of any kind upon any
          property or assets of the Company, CCI, CC Investment, CC Investment
          II, CCAIC, Crown Atlantic Holdings, Crown Atlantic Sub or Crown
          Atlantic pursuant to the terms of any agreement or instrument to which
          any of them is a party or by which any of them may be bound or under
          any to which any of their respective property or assets is subject,
          except in each case such breaches, conflicts or defaults that,
          individually or in the aggregate, would not have a Material Adverse
          Effect. For purposes of the foregoing opinion, such counsel may assume
          that any agreements referred to in clause (ii) above that are governed
          by laws other than the laws of the State of New York, are governed by
          and would be interpreted in accordance with the laws of the State of
          New York;

               (x) the Company is not an "investment company" within the meaning
          of the Investment Company Act of 1940, as amended; and

               (xi) neither the Company nor any of its subsidiaries is in
          violation of its Organizational Documents or in default in the
          performance or observance of any material obligation, agreement,
          covenant or condition contained in any indenture, mortgage, deed of
          trust, loan agreement, lease or other agreement or instrument to which
          it is a party or by which it or any of its properties may be bound.

     In addition, such counsel shall also state that such counsel has
participated in conferences with officers of the Company and with the
independent public accountants for the Company, concerning the preparation of
the Company Registration Statement and the Company Prospectus, and, although
such counsel has made certain inquiries and investigations in connection with
the preparation of the Company Registration Statement and the Company
Prospectus, it is not passing upon and does not assume any responsibility for
the accuracy or completeness of the statements contained in the Company
Registration Statement and the Company Prospectus, and has not made any
independent check or verification thereof, except insofar as such statements
relate to such counsel and to clause (vii) above, and on the basis of the
foregoing such counsel's work in connection with this matter did not disclose
any information that gave such counsel reason to believe that on the Company
Effective Date or at the Execution Time the Company Registration Statement
contains or contained any untrue statement of a material fact or omitted or
omits to state any material fact required to be stated therein or necessary to
make the statements therein not misleading or that the Company Prospectus, as of
its date and on the Closing Date includes any untrue statement of a material
fact or omitted or omits to state a

                                       23
<PAGE>

material fact necessary to make the statements therein, in the light of the
circumstances under which they were made, not misleading (it being understood
that such counsel need express no belief or opinion with respect to the
financial statements and other financial data included therein);

     The opinion of such counsel may be limited to the laws of the State of New
York, the General Corporation Law of the State of Delaware and the Federal laws
of the United States;

          (except for directors' qualifying shares) the issued shares of capital

          Company Prospectus and which are required to be disclosed and

          affect the consummation of the transactions contemplated by this
          Agreement; and

               (iii)  to the knowledge of such counsel, there are no contracts,
          agreements or understandings between the Company or any of its

          registration statement under the Act with respect to any securities of
          the Company owned or to be owned by such person or (2) to require the
          Company or any of such subsidiaries to include any securities of the
          Company owned or to be owned by such person in the securities
          registered pursuant to the Company Registration Statement or (3)
          except as described in the Company Prospectus, to require the Company
          or any of such subsidiaries to include any securities of the Company
          owned or to be owned by such person in any securities being registered
          pursuant to any other registration statement filed by the Company or
          any of such subsidiaries under the Act;

Texas, the General Corporation Law of the State of Delaware and the Federal laws

     of Delaware, or the Federal laws of the United States, to the extent they

     counsel for the Underwriters and (B) as to matters of fact,
     to the extent they deem proper, on certificates of responsible officers of

     this paragraph (d) include any supplements thereto at the Closing Date.

          (g) The Representatives shall have received (i) from Cleary, Gottlieb,
     Steen & Hamilton, counsel for the Underwriters and the Trust, such opinion

     Company, dated the Closing Date, to the effect that the signers of such

     Agreement and that:

               (i) the representations and warranties of the Company in this
          Agreement are true and correct on and as of the Closing Date with the
          same effect as if made on the Closing Date and the Company has

          its part to be performed or satisfied at or prior to the Closing Date;

               (ii) no stop order suspending the effectiveness of the Company
          Registration Statement or the use of the Company Prospectus has been
          issued and no proceedings for that purpose have been instituted or, to

               (iii)  since the date of the most recent financial statements
          included in the Company Prospectus (exclusive of any supplement
          thereto), there has been no material adverse effect on the condition
          (financial or otherwise), prospects, earnings, business or properties
          of the Company and its subsidiaries, taken as a whole, whether or not
          arising from transactions in the ordinary course of business, except
          as set forth in or contemplated in the Company Prospectus (exclusive
          of any supplement thereto).

          (j) Each of the Sellers shall have furnished to the Representatives a
     certificate, signed by [two appropriate officers of] such Seller dated the
     Closing Date, to the effect that [each] signer of such certificate has

     Prospectus, any supplements to the Company Prospectus and this Agreement
     and that the representations and warranties of such Seller in this
     Agreement are true and correct on and as of the Closing Date with the same
     effect as if made on the Closing Date and such Seller has complied with all
     the agreements and satisfied all the conditions on its part to be performed
     or satisfied at or prior to the Closing Date.

          (k) At the Execution Time and at the Closing Date, KPMG Peat Marwick
     shall have furnished to the Representatives letters, dated respectively as
     of the Execution Time and as of the Closing Date, in form and substance
     satisfactory to the Representatives, confirming that they are independent
     accountants within the meaning of the Act and the Exchange Act and the
     respective applicable published rules and regulations thereunder and
     stating in effect that:

               (i) in their opinion the audited financial statements and
          financial statement schedules included or incorporated in the Company
          Registration Statement and the Company Prospectus and reported on by
          them comply as to form with the applicable accounting requirements of
          the Act and the Exchange Act and the related published rules and
          regulations adopted by the Commission;

               (ii) on the basis of a reading of the latest unaudited financial
          statements made available by the Company and its subsidiaries;
          carrying out certain specified procedures (but not an examination in
          accordance with generally accepted auditing standards) which would not
          necessarily reveal matters of significance with respect to the
          comments set forth in such letter; a reading of the minutes of the
          meetings of the stockholders, directors and committees of the Company
          and its subsidiaries; and inquiries of certain officials of the
          Company who have responsibility for financial and accounting matters
          of the Company and its subsidiaries as to transactions and events
          subsequent to December 31, 1998 nothing came to their attention which
          caused them to believe that:

                    (A)  (1)  any unaudited financial statements included or
               incorporated by reference in the Company Registration Statement
               and the Company Prospectus do not comply as to form with
               applicable accounting requirements of the Act and with the
               related rules and regulations adopted by the Commission with
               respect to financial statements included or incorporated by
               reference in quarterly reports on form 10-Q under the Exchange
               Act; and said unaudited financial statements are not in
               conformity with generally accepted accounting principles applied
               on a basis substantially consistent with

                                       28
<PAGE>

               that of the audited financial statements included in the Company
               Registration Statement and the Company Prospectus;

                    (2) with respect to the period subsequent to December 31,
               1998    there were any material changes, at a specified date not
               more than three business days prior to the date of the letter, in
               [appropriate references to come] as compared with the amounts
               shown on the December 31, 1998, consolidated balance sheet
               included or incorporated in the Company Registration Statement
               and the Company Prospectus, or for the period from December 31,
               1998 to such specified date there were any decreases, as compared
               with the corresponding period in the preceding year, in
               [appropriate references to come], except in all instances for
               changes or decreases set forth in such letter, in which case the
               letter shall be accompanied by an explanation by the Company as
               to the significance thereof unless said explanation is not deemed
               necessary by the Representatives; or

                    (B) the information included or incorporated in the Company
               Registration Statement and Company Prospectus in response to
               Regulation S-K, Item 301 (Selected Financial Data), Item 302
               (Supplementary Financial Information), Item 402 (Executive
               Compensation) and Item 503(d) (Ratio of Earnings to Fixed
               Charges) is not in conformity with the applicable disclosure
               requirements of Regulation S-K;

               (iii)  they have performed certain other specified procedures as
          a result of which they determined that certain information of an
          accounting, financial or statistical nature (which is limited to
          accounting, financial or statistical information derived from the
          general accounting records of the Company and its subsidiaries) set
          forth in the Company Registration Statement and the Company
          Prospectus, including the information set forth under the captions
          "Summary," "Summary Unaudited Pro Forma Financial and other Data,"
          "Summary Financial and Other Data of CCIC," "Risk Factors," "Unaudited
          Pro Forma Condensed Consolidated Financial Statements" "Selected
          Financial and Other Data of CCIC," "Selected Financial and Other Data
          of CTSH," "Capitalization," "Management's Discussion and Analysis of
          Financial Condition and Results of Operations," "Business," "Selling
          Stockholder," "Recent and Proposed Transactions," and "Description of
          Capital Stock" in the Company Prospectus and the information included
          or incorporated in Items 1, 2, 6, 7, 8 and 11 of the Company's Annual
          Report on Form 10-K, incorporated in the Company Registration
          Statement and the Company Prospectus, agrees with the accounting
          records of the Company and its subsidiaries, excluding any questions
          of legal interpretation.

     References to the Company Prospectus in this paragraph (i) include any
     supplement thereto to the date of the letter.

          (l) The Shares shall have been duly approved for listing through the
     Nasdaq National Market System, and satisfactory evidence of such action
     shall have been provided to the Representatives.

                                       29
<PAGE>

          (m) The DECS shall have been approved for listing on the Nasdaq
     National Market System, subject only to official notice of issuance.

          (n) The NASD shall not have raised any objection with respect to the
     fairness and reasonableness of the underwriting terms and arrangements.

          (o) Each Fundamental Agreement shall have been executed and delivered
     by all parties thereto, and each Seller shall have delivered to the
     Collateral Agent the number of Shares required by the Collateral Agreement
     to which such Seller is a party to be initially pledged and assigned by
     such Seller thereunder in accordance with the requirements of such
     Collateral Agreement.

          (p) At the Execution Time, the Company shall have furnished to the
     Representatives a letter substantially in the form of Exhibit A hereto from
     each executive officer and director of the Company addressed to the
     Representatives relating to sales and certain other dispositions of shares
     of common stock of the Company or certain other securities, and such letter
     agreements shall be in full force and effect on the Closing Date.

          (q) Subsequent to the Execution Time or, if earlier, the dates as of
     which information is given in the Company Registration Statement (exclusive
     of any amendment thereof) and the Company Prospectus (exclusive of any
     supplement thereto), there shall not have been (i) any change or decrease
     specified in the letter or letters referred to in paragraph (i) of this
     Section 10 or (ii) any change, or any development involving a prospective
     change, in or affecting the condition (financial or otherwise), earnings,
     business or properties of the Company and its subsidiaries taken as a
     whole, whether or not arising from transactions in the ordinary course of
     business, except as set forth in or contemplated in the Company Prospectus
     (exclusive of any supplement thereto) the effect of which, in any case
     referred to in clause (i) or (ii) above, is, in the judgment of the
     Representatives, so material and adverse as to make it impractical or
     inadvisable to proceed with the offering or delivery of the DECS as
     contemplated by the Trust Registration Statement and the Company
     Registration Statement (in either case, exclusive of any amendment thereof)
     and the Trust Prospectus and the Company Prospectus (in either case,
     exclusive of any supplement thereto).

          (r) Subsequent to the Execution Time, there shall not have been any
     decrease in the rating of any of the Company's debt securities by any
     "nationally recognized statistical rating organization" (as defined for
     purposes of Rule 436(g) under the Act) or any notice given of any intended
     or potential decrease in any such rating or of a possible change in any
     such rating that does not indicate the direction of the possible change.

          (s) Prior to the Closing Date, the Company, the Trust and each of the
     Sellers shall have furnished to the Representatives such further
     information, certificates and documents as the Representatives may
     reasonably request.

          If any of the conditions specified in this Section 10 shall not have
been fulfilled when and as provided in this Agreement, or if any of the opinions
and certificates mentioned above or elsewhere in this Agreement shall not be
reasonably satisfactory in form and substance to the Representatives and counsel
for the Underwriters, this Agreement and all obligations of the Underwriters
hereunder may be canceled at, or at any time prior to, the Closing Date by the

                                       30
<PAGE>

Representatives.  Notice of such cancellation shall be given to the Trust and
the Company in writing or by telephone or facsimile confirmed in writing.

          The documents required to be delivered by this Section 10 shall be
delivered at the office of Cleary, Gottlieb, Steen & Hamilton, counsel for the
Underwriters, at One Liberty Plaza, New York, New York 10006, on the Closing
Date.

          11.  Expenses.

except to the extent the expenses of the trust paid by the Underwriters, the Up-

          12.  Indemnification and Contribution.
               --------------------------------

          (a) The Company agrees to indemnify and hold harmless each
Underwriter, the directors, officers, employees and agents of each Underwriter
and each person who controls any Underwriter within the meaning of either the
Act or the Exchange Act against any and all losses, claims, damages or
liabilities, joint or several, to which they or any of them may become subject
under the Act, the Exchange Act or other Federal or state statutory law or
regulation, at common law or otherwise, insofar as such losses, claims, damages
or liabilities (or actions in respect thereof) arise out of or are based upon
(i) any untrue statement or alleged untrue statement of a material fact
contained in the Company Registration Statement as originally filed or in any
amendment thereof, or in any Preliminary Company Prospectus or the Company
Prospectus, or in any amendment thereof or supplement thereto (each such
document, a "Company Registration Document"), or the omission or alleged
omission to state in any Company Registration Document a material fact required
to be stated therein or necessary to make the statements therein not misleading
or (ii) any untrue statement or alleged untrue statement of a material fact
contained in the Trust Registration Statement as originally filed or in any
amendment thereof, or in any Preliminary Trust Prospectus or the Trust
Prospectus, or in any amendment thereto or supplement thereto (each such
document, a "Trust Registration Document") or the omission or alleged omission
to state in any Trust Registration Document a material fact required to be
stated therein or necessary to make the statements therein not misleading; and
in each such case agrees  to reimburse each such indemnified party, as incurred,
for any legal or other expenses reasonably incurred by them in connection with
investigating or defending any such loss, claim, damage, liability or action;
provided, however, that the Company will not be liable in any such case to the
extent that any such loss, claim, damage or liability arises out of or is based
upon any such untrue statement or alleged untrue statement or omission or
alleged omission made therein in reliance upon and in conformity with written
information furnished to the Company by or on

                                       32
<PAGE>

behalf of any Underwriter through the Representatives specifically for inclusion
therein. This indemnity agreement will be in addition to any liability which the
Company may otherwise have.

          (b) Each Seller severally agrees to indemnify and hold harmless the
Company, each of its directors, each of its officers who signs the Company
Registration Statement, each Underwriter, the directors, officers, employees and
agents of each Underwriter and each person who controls the Company or any
Underwriter within the meaning of either the Act or the Exchange Act and each
other Seller, if any,  to the same extent as the foregoing indemnity from the
Company to each Underwriter, but only with reference to written information
furnished to the Company by or on behalf of such Seller specifically for
inclusion in the documents referred to in the foregoing indemnity.  This
indemnity agreement will be in addition to any liability which any Seller may
otherwise have.

          (c) Each Underwriter severally and not jointly agrees to indemnify and
hold harmless the Company, each of its directors, each of its officers who signs
the Company Registration Statement, and each person who controls the Company
within the meaning of either the Act or the Exchange Act and each Seller, to the
same extent as the foregoing indemnity to each Underwriter, but only with
reference to written information relating to such Underwriter furnished to the
Company by or on behalf of such Underwriter through the Representatives
specifically for inclusion in the documents referred to in the foregoing
indemnity.  This indemnity agreement will be in addition to any liability which
any Underwriter may otherwise have.  The Company and each Seller acknowledge
that the statements set forth in the last paragraph of the cover page regarding
delivery of the DECS and, under the heading "Plan of Distribution," (i) the list
of Underwriters and their respective participation in the sale of the DECS, (ii)
the sentences related to concessions and reallowances and (iii) the paragraph
related to stabilization, syndicate covering transactions and penalty bids in
any Preliminary Company Prospectus, the Company Prospectus, any Preliminary
Trust Prospectus or the Trust Prospectus constitute the only information
furnished in writing by or on behalf of the several Underwriters for inclusion
in any Company Preliminary Prospectus, Trust Preliminary Prospectus, the Company
Prospectus or the Trust Prospectus.

          (d) Promptly after receipt by an indemnified party under this Section
12 of notice of the commencement of any action, such indemnified party will, if
a claim in respect thereof is to be made against the indemnifying party under
this Section 12, notify the indemnifying party in writing of the commencement
thereof; but the failure so to notify the indemnifying party (i) will not
relieve it from liability under paragraph (a), (b) or (c) above unless and to
the extent it did not otherwise learn of such action and such failure results in
the forfeiture by the indemnifying party of substantial rights and defenses and
(ii) will not, in any event, relieve the indemnifying party from any obligations
to any indemnified party other than the indemnification obligation provided in
paragraph (a), (b) or (c) above.  The indemnifying party shall be entitled to
appoint counsel of the indemnifying party's choice at the indemnifying party's
expense to represent the indemnified party in any action for which
indemnification is sought (in which case the indemnifying party shall not
thereafter be responsible for the fees and expenses of any separate counsel
retained by the indemnified party or parties except as set forth below);
provided, however, that such counsel shall be satisfactory to the indemnified
party.  Notwithstanding the indemnifying party's election to appoint counsel to
represent the indemnified party in an action, the indemnified party shall have
the right to employ separate counsel (including local counsel), and the
indemnifying party shall bear the reasonable fees, costs and expenses of such
separate counsel if (i) the use of counsel chosen by the indemnifying party to
represent the indemnified party would present such counsel with a conflict of
interest, (ii) the actual or potential defendants in, or targets of, any such
action include both the indemnified party and the

                                       33
<PAGE>

indemnifying party and the indemnified party shall have reasonably concluded
that there may be legal defenses available to it and/or other indemnified
parties which are different from or additional to those available to the
indemnifying party, (iii) the indemnifying party shall not have employed counsel
satisfactory to the indemnified party to represent the indemnified party within
a reasonable time after notice of the institution of such action or (iv) the
indemnifying party shall authorize the indemnified party to employ separate
counsel at the expense of the indemnifying party. An indemnifying party will
not, without the prior written consent of the indemnified parties, settle or
compromise or consent to the entry of any judgment with respect to any pending
or threatened claim, action, suit or proceeding in respect of which
indemnification or contribution may be sought hereunder (whether or not the
indemnified parties are actual or potential parties to such claim or action)
unless such settlement, compromise or consent includes an unconditional release
of each indemnified party from all liability arising out of such claim, action,
suit or proceeding.

          (e) In the event that the indemnity provided in paragraph (a), (b) or
(c) of this Section 12 is unavailable to or insufficient to hold harmless an
indemnified party for any reason, the Company, the Sellers and the Underwriters
agree to contribute to the aggregate losses, claims, damages and liabilities
(including legal or other expenses reasonably incurred in connection with
investigating or defending same) (collectively "Losses") to which the Company,
one or more of the Sellers and one or more of the Underwriters may be subject in
such proportion as is appropriate to reflect the relative benefits received by
the Company, by the Sellers and by the Underwriters from the offering of the
DECS; provided, however, that in no case shall any Underwriter (except as may be
provided in any agreement among underwriters relating to the offering of the
DECS) be responsible for any amount in excess of the underwriting discount or
commission applicable to the DECS purchased by such Underwriter hereunder.  If
the allocation provided by the immediately preceding sentence is unavailable for
any reason, the Company, the Sellers and the Underwriters shall contribute in
such proportion as is appropriate to reflect not only such relative benefits but
also the relative fault of the Company, of the Sellers and of the Underwriters
in connection with the statements or omissions which resulted in such Losses as
well as any other relevant equitable considerations.  Benefits received by the
Company and by the Sellers shall be deemed to be equal to the total net proceeds
from the offering (before deducting expenses) received by each of them, and
benefits received by the Underwriters shall be deemed to be equal to the total
underwriting discounts and commissions, in each case as set forth on the cover
page of the Trust Prospectus.  Relative fault shall be determined by reference
to, among other things, whether any untrue or any alleged untrue statement of a
material fact or the omission or alleged omission to state a material fact
relates to information provided by the Company, the Sellers on the one hand or
the Underwriters on the other, the intent of the parties and their relative
knowledge, access to information and opportunity to correct or prevent such
untrue statement or omission.  The Company, the Sellers and the Underwriters
agree that it would not be just and equitable if contribution were determined by
pro rata allocation or any other method of allocation which does not take
account of the equitable considerations referred to above.  Notwithstanding the
provisions of this paragraph (e), no person guilty of fraudulent
misrepresentation (within the meaning of Section 11(f) of the Act) shall be
entitled to contribution from any person who was not guilty of such fraudulent
misrepresentation.  For purposes of this Section 12, each person who controls an
Underwriter within the meaning of either the Act or the Exchange Act and each
director, officer, employee and agent of an Underwriter shall have the same
rights to contribution as such Underwriter, and each person who controls the
Company within the meaning of either the Act or the Exchange Act, each officer
of the Company who shall have signed the Company Registration Statement and each
director of the Company shall have the same rights to contribution as the

          13.  Default by an Underwriter.  If any one or more Underwriters shall
               -------------------------
fail to purchase and pay for any of the DECS agreed to be purchased by such
Underwriter or Underwriters hereunder and such failure to purchase shall
constitute a default in the performance of its or their obligations under this
Agreement, the remaining Underwriters shall be obligated severally to take up
and pay for (in the respective proportions which the amount of DECS set forth
opposite their names in Schedule I hereto bears to the aggregate amount of DECS
set forth opposite the names of all the remaining Underwriters) the DECS which
the defaulting Underwriter or Underwriters agreed but failed to purchase;

provided, however, that in the event that the aggregate amount of DECS which the
- --------  -------
defaulting Underwriter or Underwriters agreed but failed to purchase shall
exceed 10% of the aggregate amount of DECS set forth in Schedule I hereto, the
remaining Underwriters shall have the right to purchase all, but shall not be
under any obligation to purchase any, of the DECS, and if such nondefaulting
Underwriters do not purchase all the DECS, this Agreement will terminate without
liability to any nondefaulting Underwriter, the Company or the Sellers.  In the
event of a default by any Underwriter as set forth in this Section 14, the
Closing Date shall be postponed for such period, not exceeding five Business
Days, as the Representatives shall determine in order that the required changes
in the Company Registration Statement, the Company Prospectus, the Trust
Registration Statement and the Trust Prospectus or in any other documents or
arrangements may be effected. Nothing contained in this Agreement shall relieve
any defaulting Underwriter of its liability, if any, to the Company or the
Sellers and any nondefaulting Underwriter for damages occasioned by its default
hereunder.

          14.  Termination.  This Agreement shall be subject to termination in
               -----------
the absolute discretion of the Representatives, by notice given to the Trust and
the Company prior to delivery of and payment for the DECS, if at any time prior
to such time (i) trading in any class of the Company's Common Stock shall have
been suspended by the Commission or the Nasdaq National Market or trading in
securities generally on the New York Stock Exchange or the Nasdaq National
Market shall have been suspended or limited or minimum prices shall have been
established on such Exchange or National Market, (ii) a banking moratorium shall
have been declared by either Federal or New York State authorities or (iii)
there shall have occurred any outbreak or escalation of hostilities, declaration
by the United States of a national emergency or war or other calamity or crisis,
the effect of which on financial markets of the United States is such as to make
it, in the sole judgment of the Representatives, impractical or inadvisable to
proceed with the offering or delivery of the DECS as contemplated by the Trust
Prospectus (exclusive of any supplement thereto).

          15.  Representations and Indemnities to Survive.  The respective
               ------------------------------------------
agreements, representations, warranties, indemnities and other statements of the
Trust, the Company and each Seller, or their respective officers, if applicable,
and of the Underwriters set forth in or made pursuant to this Agreement will
remain in full force and effect, regardless of any investigation made by or on
behalf of any Underwriter, the Trust, the Company any Seller, or any of the
officers, directors or controlling persons referred to in Section 12 hereof, and
will survive delivery of and payment for the DECS.  The provisions of Sections
11, 12 and 17 hereof shall survive the termination or cancellation of this
Agreement.

                                  WITNESSETH

          WHEREAS, the Trust is a non-diversified, closed-end management
investment company, as defined in the Investment Company Act of 1940 (the
"Investment Company Act"), formed to purchase and hold certain U.S. treasury
- -----------------------
securities (the "Treasury Securities"), to enter into and hold a forward
                 -------------------
purchase contract with one or more existing shareholders of Crown Castle
International Corp. (individually, a "Contract" and collectively, the
                                      --------
"Contracts"), to hold security for the performance of such shareholder of their
 ---------
obligations under the Contracts pursuant to related collateral agreement (the

          WHEREAS, the Trustee and the Custodian previously entered into a
Custodian Agreement dated as of April 23, 1999 (the "Original Custodian
                                                     ------------------

- ---------
certain custodial duties for the Trust and the Custodian agreed to assume such

          NOW, THEREFORE, in consideration of the premises and the mutual
covenants herein contained, the parties agree as follows:

          1.  Definitions.  Capitalized terms not otherwise defined herein shall
have the respective meanings specified in the Trust Agreement.

          2.  Appointment of Custodian; Transfer of Assets.  The Trust hereby

including but not limited to, the Contracts, the Treasury Securities, the
Temporary Investments, any cash and any other property at any time owned or held
by the Trust (other than Pledged Items (as defined in the Collateral Agreements)
held by the Collateral Agent thereunder) (collectively, the "Assets").  The

or for the disposition of the Assets pursuant to the Trust Agreement or in
respect of any action taken or suffered under the Trust Agreement in good faith,

pursuant hereto; provided that this provision shall not protect the Custodian
against any liability to which it would otherwise be subject by reason of
willful misfeasance, bad faith or gross negligence in the performance of its
duties or by reason of its reckless disregard of its obligations and duties
hereunder.  Notwithstanding any other provision of this Agreement, the Custodian

Trust and for any expenses, including counsel fees, interest, penalties and
additions to tax which the Custodian may sustain or incur with respect to such
taxes or charges.

          9.  Custodian Resignation, Succession.  (a)  The Custodian may resign
by executing an instrument in writing resigning as Custodian and delivering the
same to the Trustees, not less than 60 days before the date specified in such

notice, if any, as it may deem proper and prescribed, appoint a successor
Custodian.

jurisdiction shall enter a decree or order for relief in respect of the
Custodian in an involuntary case, or the Custodian shall commence a voluntary
case, under any applicable bankruptcy, insolvency, or other similar law now or
hereafter in effect, or any receiver, liquidator, assignee, custodian, trustee,
sequestrator (or similar official) for the Custodian or for any substantial part
of its property shall be appointed, or the Custodian shall make any general
assignment for the benefit of creditors, or shall generally fail to pay its
debts as they become due, the Trust may remove the Custodian immediately and
appoint a successor Custodian.  The termination of the Administration Agreement
or the Paying Agent Agreement shall cause the removal of the Custodian
simultaneously therewith.

successor Custodian, the Custodian hereunder shall, upon payment of all amounts
due it, execute and

Custodian all the rights and powers of the retiring Custodian; and the retiring
Custodian shall transfer, deliver and pay over to the successor Custodian the

instruments of transfer and assignment or other documents properly executed
necessary to effect such transfer and such of the records or copies thereof
maintained by the retiring Custodian in the administration hereof as may be
requested by the successor Custodian, and shall thereupon be discharged from all
duties and responsibilities hereunder. Any resignation or removal of the
Custodian shall become effective upon such acceptance of appointment by the
successor Custodian. The indemnification of the resigning Custodian provided for
hereunder shall survive any resignation, discharge or removal of the Custodian
hereunder.

Custodian may be merged or converted or with which it may be consolidated, or
any corporation resulting from any merger, conversion or consolidation to which
the Custodian shall be a party, shall be the successor Custodian hereunder and

thereto, provided that such corporation meets the requirements set forth in the
Trust Agreement.

held harmless from and against any such loss, damages, cost, expense, liability
or claim arising from its willful misfeasance, bad faith or gross negligence in
the performance of its duties, or its reckless disregard of its duties and
obligations hereunder.  Neither the Federal Reserve Book Entry System nor the
Depository Trust Company shall be deemed to be agents of the Custodian.

incur or become exposed to financial liability in the performance of its duties
hereunder or under the other agreements referred to in Section 3.1(a) hereof.

          WHEREAS the Trustees desire to engage the services of the Paying Agent

conditions of this Agreement; and

          WHEREAS the Paying Agent is qualified and willing to assume such
responsibilities and to perform such duties, subject to the supervision of the
Trustees, on the terms and conditions hereinafter set forth.

          NOW, THEREFORE, in consideration of the premises and the mutual
covenants herein contained, the parties agree as follows:

                                   ARTICLE I
                                   ---------
                                  DEFINITIONS

          1.1  Definitions.  Capitalized terms not otherwise defined herein

                                   ARTICLE II
                                   ----------

Bank of New York hereby accepts such appointment and agrees to act in accordance
with its standard procedures and the provisions of the Trust Agreement and the
provisions set forth in this Article II as Paying Agent with respect to the
DECS.  Without limiting the generality of the foregoing, The Bank of New York,
as Paying Agent, agrees that it shall establish and maintain the Trust Account,
subject to the provisions of Section 2.3 hereof.

          2.2  Certificates and Notices.  The Trustees shall deliver to the
Paying Agent the certificates and notices required to be delivered to the Paying
Agent pursuant to the Trust Agreement, and the Paying Agent shall mail or
publish such certificates or notices as required by the Trust Agreement, but the
Paying Agent shall have no responsibility to confirm or verify the accuracy of
certificates or notices of the Trustees so delivered.

          2.3  Payments and Investments.  The Paying Agent shall make payments
out of the Trust Account as provided in Section 3.3 of the Trust Agreement.  The
Paying Agent on behalf of the Trust shall effect the transactions set forth in

otherwise dispose of any Temporary Investment prior to the maturity thereof, or
to acquire additional Temporary Investments.  The Paying Agent shall hold any
Temporary Investments to its maturity and shall apply the proceeds thereof paid
upon maturity to the payment of the next succeeding Quarterly Distribution.  All
such Temporary Investments shall be selected by the Trustees from time to time
or pursuant to standing instructions from the Trustees, and the Paying Agent
shall have no liability to the Trust or any Holder or any other Person with
respect to any such Temporary Investment.

          2.4  Instructions from Administrator.  The Paying Agent shall execute
all instructions received from an officer of the Administrator, except to the
extent that they conflict with or are contrary to the terms of the Trust
Agreement or this Agreement.

                          TRANSFER AGENT AND REGISTRAR

          3.1  Original Issue of Certificates.  On the date DECS sold pursuant
to the Underwriting Agreement are originally issued, certificates for such DECS
shall be issued by the Trust, and, at the request of the Trustees, registered in
such names and such denominations as the Underwriters shall have previously
requested of the Trustees, executed manually or in facsimile by the Managing
Trustee and countersigned by the Paying Agent.  At no time shall the aggregate
number of DECS represented by such countersigned certificates exceed the number
of then outstanding DECS except as permitted by Section 3.4 hereof.

          3.2  Registry of Holders.  The Paying Agent shall maintain a registry
of the Holders of the DECS.

          3.3  Registration of Transfer of DECS.  DECS shall be registered for
transfer or exchange, and new certificates shall be issued, in the name of the
designated transferee or transferees, upon surrender of the old certificates in
form deemed by the Paying Agent properly endorsed for transfer with (a) all
necessary endorsers' signatures guaranteed in such manner and form as the Paying
Agent may require by a guarantor reasonably believed by the Paying Agent to be
responsible, (b) such assurances as the Paying Agent shall deem necessary or
appropriate to evidence the genuineness and effectiveness of each necessary
endorsement and (c) satisfactory

                                       2
<PAGE>

evidence of compliance with all applicable laws relating to the collection of
taxes or funds necessary for the payment of such taxes.

          3.4  Lost Certificates.  If there shall be delivered to the Paying
Agent (a) evidence to its satisfaction of the destruction, loss or theft of any
certificate for DECS and (b) such security or indemnity as may be required by it
to hold it and any of its agents harmless, then, in the absence of notice to the
Paying Agent that such certificate has been acquired by a bona fide purchaser,
the Managing Trustee shall execute and upon its request the Paying Agent shall
countersign and deliver, in lieu of any such destroyed, lost or stolen
certificate, a new certificate of like tenor bearing a number not
contemporaneously outstanding.  Any request by the Managing Trustee to the
Paying Agent to issue a replacement or new certificate pursuant to this Section
3.4 shall be deemed to be a representation and warranty by the Trust to the
Paying Agent that such issuance will comply with provisions of law, the Trust
Agreement and the resolutions adopted by the Trustees with respect to lost
securities.  If, after the delivery of such new certificate, a bona fide
purchaser of the original certificate in lieu of which such new certificate was
issued presents for payment such original certificate, the Trust and the Paying
Agent shall be entitled to recover such new certificate from the person to whom
it was delivered or any transferee thereof, except a bona fide purchaser, and
shall be entitled to recover upon the security or indemnity provided therefor to
the extent of any loss, damage, cost or expense incurred by the Trust or the
Paying Agent in connection therewith.  Upon the issuance of any new certificate
under this Section 3.4, the Trust and the Paying Agent may require the payment
of a sum sufficient to cover any tax or other governmental charge that may be
imposed in relation thereto and any other expenses (including the fees and
expenses of the Paying Agent) connected therewith.

          3.5  Transfer Books.  The Paying Agent shall maintain the transfer
books listing the Holders of the DECS.  In case of any written request or demand
for the inspection of the transfer books of the Trust or any other books in the
possession of the Paying Agent, the Paying Agent will notify the Trustees and
secure instructions as to permitting or refusing such inspection.  The Paying
Agent reserves the right, however, to exhibit the transfer books or other books
to any person in case it is advised by its counsel that its failure to do so
would be unlawful.

          3.6  Disposition of Canceled Certificates, Records.  The Paying Agent
shall retain certificates which have been canceled in transfer or in exchange
and accompanying documentation in accordance with applicable rules and
regulations of the Commission for six calendar years from the date of such
cancellation, and shall make such records available during this period at any
time, or from time to time, for reasonable periodic, special, or other
examinations by representatives of the Commission and the Board of Governors of
the Federal Reserve System.  Thereafter such records shall not be destroyed by
the Paying Agent but will be safely stored for possible future reference.  In
case of any request or demand for the inspection of the register of the Trust or
any other books in the possession of the Paying Agent, the Paying Agent will
notify the Trustees and secure instructions as to permitting or refusing such
inspection.  The Paying Agent reserves the right, however, to exhibit the
register or other records to any person in case it is advised by its counsel
that its failure to do so would (i) be unlawful, or (ii) expose it to liability,
unless the Trustees shall have offered indemnification satisfactory to the
Paying Agent.

     Common Stock then held by the Collateral Agent as collateral under the

     of Common Stock that would otherwise be deliverable (prior to rounding) to

     respect of such fractional shares of Common Stock in an amount equal to the
     value thereof at the Exchange Price.  Notwithstanding the foregoing, if an
     Adjustment Event shall have occurred prior to the Exchange Date then, in
     lieu of the foregoing, Seller shall

                                       8
<PAGE>

     be deemed to have instructed: (A) in the case of any cash required to be
     delivered on the Exchange Date as provided in Section 6.2, the Collateral
     Agent to wire transfer Federal (immediately available same-day) funds to an
     account designated by Purchaser; and (B) in the case of any Reported
     Securities required to be delivered by Seller in lieu of cash as provided
     in Section 6.2, the Collateral Agent to deliver to the Custodian, for the
     account of Purchaser, a specified number of Reported Securities then held
     as collateral under the Collateral Agreement, as provided in Section 6(g)
     of the Collateral Agreement.

          (ii) [In the event that by the Exchange Date any substitute collateral
     has not been replaced by shares of Common Stock (and/or, after an
     Adjustment Event, cash or Reported Securities) sufficient to meet Seller's
     obligations hereunder, delivery shall be effected by delivery by the
     Collateral Agent to the Custodian, for the account of Purchaser, of the
     market value of the shares of Common Stock required to be delivered
     hereunder, in the form of any shares of Common Stock then pledged by Seller
     plus cash generated from the liquidation of U.S. Government obligations
     then pledged by Seller (and/or, after an Adjustment Event, the market value
     of the alternative consideration required to be delivered hereunder, in the
     form of any Reported Securities then pledged, plus any cash then pledged,
     plus cash generated from the liquidation of U.S. Government obligations
     then pledged).  In such event, Seller shall be deemed to have instructed
     the Collateral Agent to liquidate and turn into cash the U.S. Government
     obligations then pledged by Seller to the extent necessary to satisfy
     Seller's obligations hereunder.]

          (iii)  Certificates representing Common Stock (or Reported Securities)
     in registered form that are part of the Contract Shares shall be registered
     in Purchaser's name or in the name of a depositary or a nominee of a
     depositary as requested by Purchaser, unless such Common Stock (and/or
     Reported Securities) is represented by one or more global certificates
     registered in the name of a depositary or a nominee of a depositary or are
     book entry securities, in which event Purchaser's interest in such
     securities shall be noted in a manner satisfactory to Purchaser and its
     counsel.

          (iv) Seller's right to deliver (or cause to be delivered) to Purchaser
     hereunder Common Stock and Reported Securities shall be conditioned upon
     such Common Stock and Reported Securities to be so delivered being
     transferable (i) by Seller to Purchaser in accordance with the provisions
     hereof and in accordance with the terms of any agreement among shareholders
     applicable to such Common Stock or Reported Securities, and (ii) by
     Purchaser, following receipt from Seller, without any restrictions not
     generally applicable to all holders of such Common Stock or Reported
     Securities, as the case may be.  If the conditions set forth in the
     preceding sentence shall not be satisfied with respect to any Common Stock
     or Reported Securities to be delivered by Seller, then, notwithstanding the
     provisions hereof, Seller shall exercise the Cash Delivery Option.

          (d) Cash Delivery Option.  At its option, Seller may deliver to

day) funds; provided that in connection with a Rollover Offering which is
consummated and as to which Seller has duly elected the Cash Delivery Option and
has

                                       9
<PAGE>

duly made a Rollover Offering Election, such cash payment shall be made no later
than the fifth Business Day after the Exchange Date. Seller may elect the Cash
Delivery Option in respect of all, but not less than all, Contract Shares and
may do so by notice to Purchaser, the Collateral Agent and the Custodian not
less than 25 Business Days prior to the Exchange Date. If Seller elects the Cash
Delivery Option and so notifies Purchaser, Purchaser shall promptly notify The
Depository Trust Company and publish a notice in a daily newspaper of national
circulation stating whether the holders of DECS will receive shares of Common

settlement is being made in connection with a Rollover Offering) and, if a
combination of Common Stock and cash, the relative proportion of each.

if each Seller electing the Cash Delivery Option (as defined in the forward
purchase agreements dated as of the date hereof between such Sellers and the
Purchaser) also makes a Rollover Offering Election pursuant to such forward
purchase agreements (each such other seller, an  "Other Rollover Seller") and
                                                  ---------------------
(iv) may be made only as to all, but not less than all, Contract Shares.

              --------------------------
given to Purchaser not earlier than , 2002 and not later than , 2002, elect to
extend the Exchange Date to , 2002, provided that such extension shall be
effective (i) only in connection with a Rollover Offering as to which the Seller
shall have duly made a Rollover Offering Election, (ii) only if Seller shall
have delivered to the Collateral Agent, in pledge under the Collateral Agreement
direct obligations of the United States of America which through the scheduled
payment of principal and interest in accordance with their terms will provide,
not later than one Business Day before , 2002, money in an amount equal to not
less than the product of (1) $______ [the aggregate interest due on all Initial
DECS for the maximum extension period] and (2) a fraction, the numerator of
which is the sum of the Firm Share Base Amount and the Additional Share Base
Amount and the denominator of which is the number of Initial DECS (the

"Additional Government Securities") and (iii) only if each Other Rollover
- ---------------------------------
Seller, if any, has previously or simultaneously elected to extend the Exchange
Date (as such term is defined in the forward purchase agreement dated as of the
date hereof between such Other Seller and the Purchaser) to the same date as is
elected by the Seller hereunder.  Unless Seller has duly elected, in connection
with a Rollover Offering, to accelerate the Exchange Date in accordance with
Section 1.3(g) hereof, Seller shall on such extended Exchange Date pay to
Purchaser by wire transfer of Federal (immediately available same-day) funds an
amount equal to not less than the product of (1) $_______ [ the aggregate
interest payable for the 3-month extension period on the Initial DECS] and (2) a
fraction, the numerator of which is the sum of the Firm Share Base Amount and
the Additional Share Base Amount and the denominator of which is the number of
Initial DECS.

          In addition, Seller hereby covenants and agrees to take all other
actions necessary to cause Purchaser to be a protected purchaser of such
Additional Government Securities, within the meaning of Article 8 of the New
York Uniform Commercial Code, as amended.

Purchaser, Purchaser shall promptly notify the Depository Trust Company and
publish a notice in a daily newspaper of national circulation stating that the
Seller has elected to extend the Exchange Date.

          (g) Acceleration of Exchange Date.  At any time after the Exchange
              -----------------------------

option but only in connection with the consummation of a Rollover Offering,
accelerate the Exchange Date to any date on or after , 2002, by notice to
Purchaser not later than  a.m. on the date to which the Exchange Date is
accelerated; provided that such acceleration shall be effective only if (i) each
Other Seller, if any, has previously or simultaneously elected to accelerate the
Exchange Date (as such term is defined in the forward purchase agreement dated
as of the date hereof between such Other Seller and the Purchaser), and (ii) at
or prior to  a.m. on such accelerated Exchange Date, Seller has paid to
Purchaser, by wire transfer to an account designated by Purchaser, in Federal
(immediately available same-day) funds, an amount equal to not less than the
product of (1) $____________ [the aggregate interest payable for the extension
period on the Initial DECS per day] times the number of days in the period from
                                    -----
(and including) , 2002 to (but excluding) the Exchange Date as accelerated,
calculated on the basis of a 360 day year consistency of twelve 30-day months
and (2) a fraction, the numerator of which is the sum of the Firm Share Base
Amount and the Additional Share Base Amount and the denominator of which is the
number of Initial DECS.

          If Seller elects to accelerate the Exchange Date and so notifies
Purchaser, Purchaser shall provide notice of such election to the holders of the
DECS not later than the accelerated Exchange Date.

          (h) Seller represents, and Purchaser acknowledges, that it is Seller's
current intention to deliver Contract Shares to the Purchaser on the Exchange
Date and not to exercise the Cash Delivery Option; however, Seller intends to
consider all relevant economic, market and business factors in ultimately
determining whether to deliver Contract Shares on the Exchange Date or to
exercise the Cash Delivery Option.

Securities for its own account during the 60 days prior to the Exchange Date.

          5.4  Notices.  Seller will cause to be delivered to Purchaser:

               ------------------

effective as promptly as practicable the transactions contemplated by this
Agreement in accordance with the terms and conditions hereof, including (i)

                                   ARTICLE VI

         ADJUSTMENT OF EXCHANGE RATE, EXCHANGE PRICE AND CLOSING PRICE
         -------------------------------------------------------------

          6.1  Dilution Adjustments.  The Exchange Rate, Exchange Price and
               --------------------
Closing Price shall be subject to adjustment successively from time to time as
follows:

          (a) Stock Dividends, Splits, Reclassifications, Etc.  If the Company
              -----------------------------------------------
shall, after the date hereof,

          (i) pay a stock dividend or make a distribution, in either case, with
     respect to Common Stock in shares of such stock;

          (ii) subdivide or split its outstanding shares of Common Stock into a
     greater number of shares;

          (iii)  combine its outstanding shares of Common Stock into a smaller
     number of shares; or

          (iv) issue by reclassification (other than a reclassification pursuant
     to clause (b), (c), (d) or (e) of the definition of Adjustment Event) of
     its shares of Common Stock any other equity securities of the Company;

then, in each such case, the Exchange Rate shall be multiplied by a Dilution
Adjustment equal to the number of shares of common stock (or the fraction
thereof) that a holder who held one share of Common Stock immediately prior to
such event would be entitled solely by reason of such event to hold immediately
after such event.  In the case of the reclassification of any shares of Common
Stock into any other equity securities of the Company other than the Common
Stock, such other equity securities shall be deemed shares of Common Stock for
all purposes hereunder.  The Exchange Price and Closing Price shall also be
adjusted in the manner described in paragraph (c).

                                       15
<PAGE>

          (b) Right or Warrant Issuances.  If the Company shall, after the date
              --------------------------
hereof, issue, or declare a record date in respect of an issuance of, rights or
warrants (other than rights to purchase Common Stock pursuant to a plan for the
reinvestment of dividends or interest) to all holders of Common Stock entitling
them to subscribe for or purchase shares of Common Stock at a price per share
less than the Market Price of the Common Stock on the Business Day next
following the record date for the determination of holders of Common Stock
entitled to receive such rights or warrants, then, in each such case, the
Exchange Rate shall be multiplied by the following Dilution Adjustment: a
fraction, of which the numerator shall be (A) the number of shares of Common
Stock outstanding on the record date for the issuance of such rights or warrants
plus (B) the number of additional shares of Common Stock offered for
subscription or purchase pursuant to such rights or warrants, and of which the
denominator shall be (x) the number of shares of Common Stock outstanding on the
record date for the issuance of such rights or warrants plus (y) the number
specified in clause (B) above multiplied by the quotient of the exercise price
of such rights or warrants divided by the Market Price of the Common Stock on
the Business Day next following the record date for the determination of holders
of Common Stock entitled to receive such rights or warrants.  To the extent that
such rights or warrants expire prior to the Exchange Date and shares of Common
Stock are delivered with respect to less than all of such rights or warrants
prior to such expiration, the Exchange Rate shall be readjusted to the Exchange
Rate which would then be in effect had such adjustments for the issuance of such
rights or warrants been made upon the basis of delivery of only the number of
shares of Common Stock actually delivered pursuant to such rights or warrants.
The Exchange Price and Closing Price shall also be adjusted in the manner
described in paragraph (c).

          (c) Corresponding Adjustments to Exchange Price; Adjustment of Closing
              ------------------------------------------------------------------
Price in Certain Circumstances.
- ------------------------------

          (i) If any adjustment is made to the Exchange Rate pursuant to
     paragraph (a) or (b) of this Section 6.1, an adjustment shall also be made
     to the Exchange Price as such term is used throughout the definition of
     Exchange Rate.  The required adjustment to the Exchange Price shall be made
     at the Exchange Date by multiplying the Exchange Price by the cumulative
     Dilution Adjustment.

          (ii) If, during any Calculation Period used in calculating the
     Exchange Price, the Market Price or the Transaction Value, there shall
     occur any event requiring an adjustment to be effected pursuant to this
     Section 6.1, then the Closing Price for each Trading Day in the Calculation
     Period occurring prior to the day on which such adjustment is effected
     shall be adjusted by being divided by the relevant Dilution Adjustment.

          (d) Timing of Dilution Adjustments.  Each Dilution Adjustment shall be
              ------------------------------
effected:

          (i) in the case of any dividend, distribution, or issuance of rights
     or warrants, at the opening of business on the Business Day next following
     the record date for determination of holders of Common Stock entitled to
     receive such dividend, distribution or issuance or, if the announcement of
     any such dividend, distribution or issuance is after

                                       16
<PAGE>

     such record date, at the time such dividend, distribution or issuance shall
     be announced by the Company; and

          (ii) in the case of any subdivision, split, combination or
     reclassification, on the effective date of such transaction.

          (e) General; Failure of Dilution Event to Occur.  All Dilution
              -------------------------------------------
Adjustments shall be rounded upward or downward to the nearest 1/10,000th (or if
there is not a nearest 1/10,000th to the next higher 1/10,000th).  No adjustment
in the Exchange Rate shall be required unless such adjustment would require an
increase or decrease of at least one percent therein; provided, however, that
any adjustments which by reason of this sentence are not required to be made
shall be carried forward and taken into account in any subsequent adjustment.
If any announcement or declaration of a record date in respect of a dividend,
distribution or issuance requiring an adjustment pursuant to this Section 6.1
shall subsequently be canceled by the Company, or such dividend, distribution or
issuance shall fail to receive requisite approvals or shall fail to occur for
any other reason, then, upon such cancellation, failure of approval or failure
to occur, the Exchange Rate shall be readjusted to the Exchange Rate which would
then have been in effect had adjustment for such event not been made.  If an
Adjustment Event shall occur after the occurrence of one or more events
requiring an adjustment pursuant to this Section 6.1, the Dilution Adjustments
previously applied to the Exchange Rate in respect of such events shall not be
rescinded but shall be applied to the new Exchange Rate provided for under
Section 6.2.

          6.2  Adjustment for Consolidation, Merger or Other Adjustment Event.
               --------------------------------------------------------------
In the event of (a) any dividend or distribution by the Company to all holders
of Common Stock of evidences of its indebtedness or other assets (excluding any
dividends or distributions referred to in Section 6.1(a)(i), any other equity
securities issued pursuant to a reclassification referred to in Section
6.1(a)(iv) and any Ordinary Cash Dividends) or any issuance by the Company to
all holders of Common Stock of rights or warrants to subscribe for or purchase
any of its securities (other than rights or warrants referred to in Section
6.1(b)), (b) any consolidation or merger of the Company with or into another
entity (other than a merger or consolidation in which the Company is the
continuing corporation and in which the Common Stock outstanding immediately
prior to the merger or consolidation is not exchanged for cash, securities or
other property of the Company or another corporation), (c) any sale, transfer,
lease or conveyance to another corporation of the property of the Company as an
entirety or substantially as an entirety, (d) any statutory exchange of
securities of the Company with another corporation (other than in connection
with a merger or acquisition) or (e) any liquidation, dissolution or winding up
of the Company (any such event described in clause (a), (b), (c), (d) or (e), an
"Adjustment Event"), the Exchange Rate shall be adjusted so that on the Exchange
 ----------------
Date Seller shall deliver to Purchaser, in lieu of or (in the case of an
Adjustment Event described in clause (a) above) in addition to, the Contract
Shares, cash in an amount equal to:

     (A)  if the Exchange Price is greater than the Threshold Appreciation
          Price, multiplied by the Transaction Value (as defined below);

                                       17
<PAGE>

     (B)  if the Exchange Price is less than or equal to the Threshold
          Appreciation Price but greater than the Initial Price, the product of
          (x) the Initial Price divided by the Exchange Price multiplied by (y)
          the Transaction Value; and

     (C)  if the Exchange Price is less than or equal to the Initial Price, the
          Transaction Value;

          provided, however, that if the consideration received by all holders
          --------  -------
of Common Stock in such Adjustment Event does not and may not at the option of
such holders include Reported Securities, then (except in the case of an
Adjustment Event solely of the type described in clause (a) above) (i) Seller's
delivery obligations hereunder will be accelerated and promptly upon
consummation of the Adjustment Event Seller will be required to deliver to
Purchaser cash in an amount equal to (x) if the Transaction Value is greater
than the Threshold Appreciation Price,   multiplied by the Transaction Value,
(y) if the Transaction Value is less than or equal to the Threshold Appreciation
Price but greater than Initial Price, the Initial Price, and (z) if the
Transaction Value is less than or equal to the Initial Price, the Transaction
Value.

          Following an Adjustment Event, the Exchange Price, as such term is
used throughout the definition of Exchange Rate, shall be deemed to equal (A) if
shares of Common Stock are outstanding at the Exchange Date, the Exchange Price
of the Common Stock, as adjusted pursuant to Section 6.1(c), otherwise zero,
plus (B) the Transaction Value.

          Notwithstanding the foregoing, with respect to any Reported Securities
(as defined below) received by holders of Common Stock in an Adjustment Event,
Seller shall, in lieu of delivering cash in respect of such Reported Securities
as described above, deliver a number of such Reported Securities with a value,
as determined in accordance with clause (ii) of the definition of Transaction
Value, equal to all cash amounts that would otherwise be deliverable in respect
of Reported Securities received in such Adjustment Event, unless Seller has made
an election to exercise the Cash Delivery Option or such Reported Securities
have not yet been delivered to the holders entitled thereto following such
Adjustment Event or any record date with respect thereto.  If, following any
Adjustment Event, any Reported Security ceases to qualify as a Reported
Security, then (x) Seller shall not deliver such Reported Security but instead
shall deliver of an equivalent amount of cash and (y) notwithstanding clause
(ii) of the definition of Transaction Value, the Transaction Value of such
Reported Security shall mean the fair market value of such Reported Security on
the date such security ceases to qualify as a Reported Security, as determined
by a nationally recognized investment banking firm retained for this purpose by
the Administrator.

          "Transaction Value" means (i) for any cash received in any Adjustment
           -----------------
Event, the amount of cash received per share of Common Stock, (ii) for any
Reported Securities received in any Adjustment Event, an amount equal to (x) the
average Closing Price per security of such Reported Securities on the 20 Trading
Days immediately prior to (but not including) the Exchange Date multiplied by
(y) the number of such Reported Securities (as adjusted pursuant to the
definition thereof) received per share of Common Stock and (iii) for any
property received in any Adjustment Event other than cash or Reported
Securities, an amount equal to the fair market value of the property received
per share of Common Stock on the date such property is received, as determined
by a nationally recognized investment banking firm retained for this purpose by

                                       18
<PAGE>

the Administrator; provided, however, that in the case of clause (ii), (x) with
respect to securities that are Reported Securities by virtue of only clause (iv)
of the definition of Reported Securities, Transaction Value with respect to any
such Reported Security means the average of the mid-point of the last bid and
ask prices for such Reported Security as of the Exchange Date from each of at
least three nationally recognized investment banking firms retained for such
purpose by the Administrator multiplied by the number of such Reported
Securities (as adjusted pursuant to the definition thereof) received per share
of Common Stock and (y) with respect to all other Reported Securities, if there
are not 20 Trading Days for any particular Reported Security occurring after the
60th calendar day immediately prior to, but not including, the Exchange Date,
Transaction Value with respect to such Reported Security means the fair market
value per security of such Reported Security as of the Exchange Date as
determined by a nationally recognized investment banking firm retained for such
purpose by the Administrator multiplied by the number of such Reported
Securities (as adjusted pursuant to the definition thereof) received per share
of Common Stock.  For purposes of calculating the Transaction Value, any cash,
Reported Securities or other property receivable in an Adjustment Event shall be
deemed to have been received immediately prior to the close of business on the
record date for such Adjustment Event or, if there is no record date for such
Adjustment Event, immediately prior to the close of business on the effective
date of such Adjustment Event.

          "Reported Securities" means any securities received in an Adjustment
           -------------------
Event that (A) are (i) listed on a United States national securities exchange,
(ii) reported on a United States national securities system subject to last sale
reporting, (iii) traded in the over-the-counter market and reported on the
National Quotation Bureau or similar organization or (iv) for which bid and ask
prices are available from at least three nationally recognized investment
banking firms and (B) are either (x) perpetual equity securities or (y) non-
perpetual equity or debt securities with a stated maturity after the Exchange
Date.  The number of shares of any Reported Securities included in the
calculation of Transaction Value pursuant to clause (ii) of the definition
thereof shall be subject to adjustment if any event that would, had it occurred
with respect to the Common Stock or the Company, have required an adjustment
pursuant to Section 6.1 or 6.2, shall occur with respect to such Reported
Securities or the issuer thereof subsequent to the date the Adjustment Event is
consummated.  Adjustment for such subsequent events shall be as nearly
equivalent as practicable to the adjustments provided for in Section 6.1 or 6.2,
as applicable.

                                  ARTICLE VII

                                  ACCELERATION

          If one or more of the following events (each an "Event of Default")
                                                           ----------------

          (a) Seller or any Other Seller shall commence a voluntary case or
other proceeding seeking a liquidation, reorganization or other relief with
respect to itself or its debts under any bankruptcy, insolvency or other similar
law now or hereafter in effect or seeking the appointment of a trustee,
receiver, liquidator, custodian or other similar official of it or any
substantial part of its property, or shall consent to any such relief or to the
appointment of or

                                       19
<PAGE>

taking possession by any such official in an involuntary case or other
proceeding commenced against it, or shall take any action to authorize any of
the foregoing;

          (b) an involuntary case or other proceeding shall be commenced against
Seller or any Other Seller seeking liquidation, reorganization or other relief
with respect to it or its debts under any bankruptcy, insolvency or other
similar law now or hereafter in effect or seeking the appointment of a trustee,
receiver, liquidator, custodian or other similar official of it or any
substantial part of its property; or an order for relief shall be entered
against any Seller or any Other Seller under the federal bankruptcy laws as now
or hereafter in effect; or

          (c) a Collateral Event of Default within the meaning of the Collateral
Agreement;

          then an "Acceleration Date" shall occur, Seller's rights under Section
                   -----------------
     1.3(d), (e) (f) and (g) shall terminate immediately and (i) in the case of
     clause (c), Seller shall become obligated to the extent permitted by law to
     deliver to Purchaser (and shall be deemed to instruct the Collateral Agent
     to deliver to the Custodian, for the account of Purchaser, and to liquidate
     and turn into cash the U.S. Government obligations then pledged by Seller
     to the extent necessary to satisfy such obligation) the Contract Shares, in
     the form of the shares of Common Stock then pledged by Seller, or cash
     generated from the liquidation of U.S. Government obligations then pledged
     by Seller, or a combination thereof (or, after an Adjustment Event, the
     alternate consideration to be delivered, in the form of Reported Securities
     then pledged, cash then pledged, cash generated from the liquidation of
     U.S. Government obligations then pledged, or a combination thereof); or

          (ii) in the case of clauses (a) or (b), Seller shall become obligated
     to the extent permitted by law to deliver to Purchaser (and shall be deemed
     to instruct the Collateral Agent to deliver to the Custodian, for the
     account of Purchaser, and to liquidate and turn into cash the U.S.
     Government obligations then pledged by Seller to the extent necessary to
     satisfy such obligation) a number of shares of Common Stock, in the form of
     the shares of Common Stock then pledged by Seller, or cash generated from
     the liquidation of U.S. Government obligations then pledged by Seller, or a
     combination thereof (or, after an Adjustment Event, the alternate
     consideration to be delivered, in the form of Reported Securities then
     pledged, cash then pledged, cash generated from the liquidation of U.S.
     Government obligations then pledged, or a combination thereof), with an
     aggregate value (based on the Closing Price on the Acceleration Date) equal
     to the Acceleration Value (as defined below).

          "Acceleration Value" means an amount determined by the Administrator
           ------------------
on the basis of quotations from Independent Dealers (as defined below).  Each
quotation will be for an amount that would be paid to the relevant Independent
Dealer in consideration of an agreement between Purchaser and such Independent
Dealer that would have the effect of preserving for Purchaser the economic
equivalent of the payments and deliveries that Purchaser would, but for the
occurrence of the Acceleration Date, have been entitled to receive after the
Acceleration Date hereunder (taking into account any adjustments to the Exchange
Rate that may have been effected on or prior to the Acceleration Date).  On or
as soon as reasonably practicable following

                                       20
<PAGE>

the Acceleration Date, the Administrator will request each Independent Dealer to
provide its quotation as soon as reasonably practicable, but in any event within
two Business Days. The Administrator shall compute the Acceleration Value upon
receipt of each Independent Dealer's quotation, provided that if, at the close
of business on the fourth Business Day following the Acceleration Date, the
Administrator shall have received quotations from fewer than four of the
Independent Dealers, the Administrator shall compute the Acceleration Value
using the quotations, if any, it shall have received at or prior to such time.
If four quotations are provided, the Acceleration Value will be the arithmetic
mean of the two quotations remaining after disregarding the highest and lowest
quotations. (For this purpose, if more than one quotation has the same highest
or lowest value, then one of such quotations shall be disregarded.) If two or
three quotations are provided, the Acceleration Value will be the arithmetic
mean of such quotations. If one quotation is provided, the Acceleration Value
will be equal to such quotation. If no quotations are provided, the Acceleration
Value will be the aggregate value (based on the Closing Price on the
Acceleration Date) of the number of shares of Common Stock (or, after an
Adjustment Event, Reported Securities, cash or a combination thereof) that would
be required to be delivered hereunder on the Acceleration Date if the Exchange
Date were redefined to be the Acceleration Date.

          "Independent Dealers" means four nationally recognized independent
           -------------------
investment banking firms selected in good faith by the Administrator.

          As promptly as reasonably practicable after receipt of the quotations
on which the Acceleration Value is based (or, as the case may be, after failure
to receive any such quotations within the time period prescribed above),
Purchaser shall deliver to Seller and the Collateral Agent a notice specifying
the number of shares of Common Stock (or, after an Adjustment Event, the
alternate consideration) required to be delivered by Seller.  Purchaser and
Seller agree that the obligations contained in clauses (i) and (ii) above are a
reasonable pre-estimate of loss and not a penalty.  Such amount is payable for
the loss of bargain and Purchaser will not be entitled to recover additional
damage as a consequence of loss resulting from an Event of Default.

Purchaser shall be responsible for the effectuation and calculation of any
adjustment pursuant to Article VI hereof and shall furnish Seller notice of any
such adjustment and shall provide Seller reasonable opportunity to review the
calculations pertaining to any such adjustment.  If, pursuant to the terms and
conditions hereof, the Administrator shall be required to retain a nationally
recognized independent investment banking firm for any purpose provided herein,
such nationally recognized independent investment banking firm shall be selected
and retained by the Administrator only after consultation with Seller; provided,
however, that Seller shall be deemed to have waived his right to consult if
Seller fails to consult within five Business Days of notice being sent by the
Administrator to Seller seeking consultation.  Purchaser may delegate the
effectuation and calculation of any such adjustments to its Administrator.

     Collateral Agent to the transfer agent for the Common Stock prior to any
     such delivery to the holders of DECS) no Transfer Restrictions exist with

     Liens (other than the Lien created by this Collateral Agreement) and
     Transfer Restrictions (except for any legend as provided in Section 3(e)
     hereof).  Upon delivery of the Pledged Items described in paragraphs (b)
     and (c) of Section 1 to the Collateral Agent hereunder, the Collateral
     Agent will obtain a valid, first priority perfected security interest in,
     and a first lien upon,

                                       6
<PAGE>

     such Pledged Items subject to no other Lien. None of the Collateral is or
     shall be pledged by the Pledgor as collateral for any other purpose.

               (g) Control of Seller.  [                       ] is solely
                   -----------------

               (h) Interest in Seller.  [                        ] owns 100% of
                   ------------------

          4.  Representations and Warranties of the Collateral Agent.
              ------------------------------------------------------

          The Collateral Agent represents and warrants to the Pledgor and the
Trust that:

               (a) Corporate Existence and Power.  The Collateral Agent is a
                   -----------------------------
     banking corporation, duly incorporated, validly existing and in good
     standing under the laws of the jurisdiction of its incorporation, and has
     all corporate powers and all material governmental licenses,
     authorizations, consents and approvals required to enter into, and perform
     its obligations under, this Collateral Agreement.

               (b) Authorization and Non-Contravention.  The execution, delivery
                   -----------------------------------
     and performance by the Collateral Agent of this Collateral Agreement have
     been duly authorized by all necessary corporate action on the part of the
     Collateral Agent (no action by the shareholders of the Collateral Agent
     being required) and do not and will not violate, contravene or constitute a
     default under any provision of applicable law or regulation or of the
     charter or by-laws of the Collateral Agent or of any material agreement,
     judgment, injunction, order, decree or other instrument binding upon the
     Collateral Agent.

               (c) Binding Effect.  This Collateral Agreement constitutes a
                   --------------
     valid and binding agreement of the Collateral Agent enforceable against the
     Collateral Agent in accordance with its terms.

          5.  Certain Covenants of the Pledgor.
              --------------------------------

          The Pledgor agrees that, so long as any of its obligations under the
     Purchase Agreement remain outstanding:

               (a) Title to Collateral.  The Pledgor shall at all times
                   -------------------
     hereafter have good and marketable title to the Collateral pledged
     hereunder, free of all Liens (other than the Liens created by this
     Collateral Agreement) and Transfer Restrictions (except for any legend as
     provided in Section 3(e) hereof), and, subject to the terms of this
     Collateral Agreement, will at all times hereafter have good, right and
     lawful authority to assign, transfer and pledge such Collateral and all
     such additions thereto and substitutions therefor under this Collateral
     Agreement.

               (b) Pledge Value Requirement.  The Pledgor shall cause the
                   ------------------------
     aggregate Pledge Value of the Collateral to be equal to or greater than the
     Pledge Value

                                       7
<PAGE>

     Requirement at all times, and shall pledge additional Collateral in the
     manner described in Section 6(d) as necessary to cause such requirement to
     be met.

               (c) Pledge upon Adjustment Event.  Upon the occurrence of an
                   ----------------------------
     Adjustment Event, the Pledgor shall immediately cause to be delivered to
     the Collateral Agent, in the manner provided in Section 6(d): (i) U.S.
     Government Securities having an aggregate Market Value at least equal to
     105% of the Cash Delivery Obligations, if any; and (ii) Reported Securities
     in an amount at least equal to the Maximum Deliverable Number thereof (if
     any), or, at Pledgor's election, U.S. Government Securities having an
     aggregate Market Value at least equal to 150% of such Maximum Deliverable
     Number of Reported Securities; in each case to be held as [substitute or]
     additional Collateral hereunder.

               (d) Composition of Pledged Items.  [Notwithstanding the Pledgor's
                   ----------------------------
     right to substitute Collateral pursuant to Section 6(b),] the Pledgor shall
     cause the Collateral to include, on the Exchange Date, unless Pledgor shall
     have exercised its Cash Delivery Option, a number of shares of Common Stock
     (and/or, if an Adjustment Event shall have occurred, Reported Securities)
     at least equal to the number of shares of Common Stock (and/or, if an
     Adjustment Event shall have occurred, Reported Securities) required to be
     delivered under the Purchase Agreement on the Exchange Date.  If the
     Pledgor exercises its Cash Delivery Option, then the Pledgor shall cause
     the Collateral for the Cash Delivery Obligations to consist entirely of
     U.S. Government Securities or cash at all times from and after the date 25
     Business Days prior to the Exchange Date, and, if the Pledgor shall have
     extended the Exchange Date pursuant to Section 1.3(f) of the Purchase
     Agreement, the Pledgor shall cause Collateral for Pledgor's obligations in
     connection with Pledgor's extension of the Exchange Date to consist
     entirely of Additional Government Securities or cash.

               (e) Further Assurances.  The Pledgor shall, at its expense and in
                   ------------------
     such manner and form as the Trust or the Collateral Agent may require,
     give, execute, deliver, file and record any financing statement, notice,
     instrument, document, agreement or other papers that may be necessary or
     desirable in order to create, preserve, perfect, substantiate or validate
     any security interest granted pursuant hereto or to enable the Collateral
     Agent to exercise and enforce its rights and the rights of the Trust
     hereunder with respect to such security interest.  To the extent permitted
     by applicable law, the Pledgor hereby authorizes the Collateral Agent to
     execute and file, in the name of the Pledgor or otherwise, Uniform
     Commercial Code financing or continuation statements (which may be carbon,
     photographic, photostatic or other reproductions of this Agreement or of a
     financing statement relating to this Agreement) which the Collateral Agent
     in its sole discretion may deem necessary or appropriate to further
     perfect, or maintain the perfection of the security interests granted
     hereby.

               [(f)  Control of [                  ] GRAT.  [
                     ------------------------------------
     ] GRAT shall be controlled by [                            ] and [
     ] shall be the sole trustee of such trust so long as [s]he shall have legal
     capacity so to act.]

               (g) The Pledgor shall not consolidate with or merge with or into,
     or transfer all or substantially of its assets to, any other Person unless:

               (i) either (x) the Pledgor shall be the resulting or surviving
          entity or (y) such other Person is an entity organized and existing
          under the laws of the United States, a State thereof or the District
          of Columbia, such other Person expressly assumes by supplemental
          agreement executed and delivered to the Trust, in form satisfactory to
          counsel to the Trust, all the obligations of the Pledgor under the
          Underwriting Agreement, Collateral Agreement, the Reimbursement
          Agreement, and this Agreement (in which case all such obligations of
          the Pledgor shall terminate); and

               (ii) the Pledgor shall deliver to the Trust prior to the proposed
          transaction an Officer's Certificate and an Opinion of Counsel, each
          of which shall state that such consolidation, merger or transfer and
          such supplemental agreement comply with this Section [5(g)] and that
          all conditions precedent herein provided for relating to such
          transaction have been complied with.

               Upon any consolidation or merger, or any transfer of all or
     substantially all of the assets of the Pledgor in accordance with this
     Section [5(g)], the successor entity formed by such consolidation or into
     which the Pledgor is merged or to which such transfer is made shall succeed
     to, and be substituted for, and may exercise every right and power of the
     Pledgor under this Agreement with the same effect as if such successor
     entity had been named as the Pledgor herein, and the predecessor entity,
     shall be relieved of any further obligation under this Agreement.

          6.  Administration of the Collateral and Valuation of the Securities.
              ----------------------------------------------------------------

          (a) Valuation of Collateral.  The Collateral Agent shall determine on
              -----------------------
each Business Day whether the Pledge Value is at least equal to the Pledge Value
Requirement and whether an Insufficiency Determination or Collateral Event of
Default shall have occurred and, from and after any substitution of U.S.
Government Securities for pledged Common Stock or Reported Securities pursuant
to paragraph (b) of this Section 6, shall determine the Pledge Value on each
Business Day and shall provide written notice of the Pledge Value to the
Pledgor.

          [(b)  Substitution of Collateral.  The Pledgor may substitute
                --------------------------
Collateral in accordance with the following provisions:

               (1) Unless an Event of Default or a failure by the Pledgor to
     meet any of its obligations under Section 5(b) or (c) hereof has occurred
     and is continuing, the Pledgor shall have the right at any time and from
     time to time to deposit Eligible Collateral with the Collateral Agent in
     substitution for Pledged Items previously deposited hereunder ("Prior
                                                                     -----
     Collateral") and to obtain the release from the Lien hereof of such Prior
     ----------
     Collateral.

               (2) If the Pledgor wishes to deposit Eligible Collateral with the
     Collateral Agent in substitution for Prior Collateral, the Pledgor shall
     (i) give written notice to the Collateral Agent identifying the Prior
     Collateral to be released from the Lien

                                       9
<PAGE>

     hereof, (ii) deliver to the Collateral Agent concurrently with such
     Eligible Collateral a certificate of the Pledgor substantially in the form
     of Exhibit A hereto and dated the date of such delivery, (A) identifying
     the items of Eligible Collateral being substituted for the Prior Collateral
     and the Prior Collateral that is to be transferred to the Pledgor and (B)
     certifying that the representations and warranties contained in such
     Exhibit A hereto are true and correct on and as of the date thereof and
     (iii) deliver to the Collateral Agent concurrently with such Eligible
     Collateral an opinion (dated the date of such delivery) of counsel,
     substantially similar to those delivered by Kirkpatrick & Lockhart at the
     Firm Purchase Date with respect to similar matters, addressed to the
     Collateral Agent confirming the representations contained in the second
     sentence of paragraph 3(b) of Exhibit A hereto. The Pledgor hereby
     covenants and agrees to take all actions required under Section 6(d) and
     any other actions necessary to create for the benefit of the Collateral
     Agent a valid, first priority perfected security interest in, and a first
     lien upon, such Eligible Collateral deposited with the Collateral Agent in
     substitution for Prior Collateral.

               (3) No such substitution shall be made unless and until the
     Collateral Agent shall have determined that the aggregate Pledge Value of
     all of the Collateral at the time of such proposed substitution, after
     giving effect to the proposed substitution, shall at least equal the Pledge
     Value Requirement.]

          (c) Additional Collateral.  The Pledgor may pledge additional
              ---------------------
Collateral (excluding Additional Government Securities) hereunder at any time
and may pledge Additional Government Securities hereunder at any time prior to
or simultaneously with Pledgor's election to extend the Exchange Date pursuant
to Section 1.3(f) of the Purchase Agreement.  Concurrently with the delivery of
any additional Eligible Collateral, the Pledgor shall deliver (i) in the case of
Eligible Collateral consisting of Additional Government Securities, a
certificate of the Pledgor substantially in the form of Exhibit B hereto, or in
the case of all other Eligible Collateral, a certificate of the Pledgor
substantially in the form of Exhibit C hereto and dated the date of such
delivery, in each case (A) identifying the additional items of Eligible
Collateral being pledged and (B) certifying that with respect to such items of
additional Eligible Collateral the representations and warranties contained in
such Exhibit B or Exhibit C, as the case may be, hereto are true and correct on
and as of the date thereof and (ii) an opinion, dated the date of such delivery,
of counsel addressed to the Collateral Agent, substantially similar to those
delivered by Kirkpatrick & Lockhart at the Firm Purchase Date with respect to
similar matters, confirming the representations contained in the second sentence
of paragraph 2(b) of Exhibit B or Exhibit C, as the case may be, hereto.  The
Pledgor hereby covenants and agrees to take all actions required under Section
6(d) and any other actions necessary to create for the benefit of the Collateral
Agent a valid, first priority perfected security interest in, and a first lien
upon, such additional Eligible Collateral.

          (d) Delivery of Collateral.  The Pledgor shall deliver all Collateral
              ----------------------
to the Collateral Agent in accordance with the following provisions:

               (1) Pledged Common Stock.  In the case of Collateral consisting
                   --------------------
     of Common Stock, by delivery of certificates evidencing such Common Stock,
     indorsed in blank (together with all signature guarantees and any other
     documents necessary to

                                       10
<PAGE>

     permit the Collateral Agent to effect the re-registration thereof without
     further action by the Pledgor) or registered in the name of the Collateral
     Agent or its nominee or, if such Common Stock is not issuable in
     certificated form but is held in book entry form by The Depository Trust
     Company, by transfer to an account of the Collateral Agent or to an account
     (other than an account of the Pledgor) designated by the Collateral Agent
     with The Depository Trust Company;

               (2) Pledged Government Securities.  In the case of Collateral
                   -----------------------------
     consisting of U.S. Government Securities or Additional Government
     Securities, by transfer thereof through the Book Entry System of the
     Federal Reserve System to the account of the Collateral Agent or to an
     account (other than an account of the Pledgor) designated by the Collateral
     Agent; and

               (3) Pledged Reported Securities.  In the case of Collateral
                   ---------------------------
     consisting of Reported Securities, by delivery of certificates evidencing
     such Reported Securities, indorsed in blank (together with all signature
     guarantees and any other documents necessary to permit the Collateral Agent
     to effect the re-registration thereof without further action by the
     Pledgor) or registered in the name of the Collateral Agent or its nominee
     or, if such Reported Securities are not issuable in certificated form but
     are held in book entry form by The Depository Trust Company, by transfer to
     an account of the Collateral Agent or to an account (other than an account
     of the Pledgor) designated by the Collateral Agent with The Depository
     Trust Company.  Each such delivery of Reported Securities shall be
     accompanied by an opinion of counsel, substantially similar to those
     delivered by Kirkpatrick & Lockhart at the Firm Purchase Date with respect
     to similar matters, satisfactory to the Collateral Agent that the
     Collateral Agent has obtained a valid, first priority perfected security
     interest in, and a first lien upon, such Reported Securities.

          Upon delivery of any Pledged Item under this Collateral Agreement, the
Collateral Agent shall examine such Pledged Item and any opinions and
certificates delivered pursuant to Sections 6(b), 6(c), 6(d)(3) or otherwise
pursuant to the terms hereof in connection therewith to determine that they
comply as to form with the requirements for Eligible Collateral.  Immediately
following the delivery to the Collateral Agent of any Collateral in the form of
certificates indorsed in blank, the Collateral Agent shall cause all such
certificates to be re-registered on the books of the applicable transfer agent
into the name of the Collateral Agent or its nominee, and shall thereafter
maintain all such Collateral in such form until the termination of this
Agreement; provided, however, that at any time following such delivery to the
           -----------------
Collateral Agent, the Collateral Agent may cause any such certificates to be
deposited with The Depository Trust Company and thereafter hold such
certificates in book entry form in an account (other than an account of Pledgor)
designated by the Collateral Agent.  The Pledgor hereby designates the
Collateral Agent as the person in whose name any Collateral held in book entry
form in the Federal Reserve System shall be registered.

          (e)  Insufficiency Determination.
               ---------------------------

               (1) If on any Business Day the Collateral Agent determines that
     the aggregate Pledge Value of the Collateral is less than the Pledge Value
     Requirement (any

                                       11
<PAGE>

     such determination, an "Insufficiency Determination"), the Collateral Agent
                             ---------------------------
     shall, by telephone call to an Authorized Representative of the Pledgor
     followed by a written confirmation of such call, promptly notify the
     Pledgor of such determination and of the amount of the insufficiency.

               (2) If, by 4:00 p.m., New York City time on the Business Day
     following the day on which telephonic notice shall have been given pursuant
     to the preceding paragraph (e)(1), the Pledgor shall have failed to
     deliver, in the manner set forth in paragraphs (c) and (d) of this Section
     6, sufficient additional Eligible Collateral so that, after giving effect
     to such delivery (and taking into account that Common Stock and Reported
     Securities in excess of the Maximum Deliverable Number thereof shall not
     constitute Eligible Collateral), the aggregate Pledge Value of the
     Collateral, as of such Business Day, is at least equal to the Pledge Value
     Requirement, then (x) the Collateral Requirement with respect to any U.S.
     Government Securities pledged hereunder (other than in respect of Cash
     Delivery Obligations) shall be increased from 150% to 200%, and (y) unless
     a Collateral Event of Default shall have occurred and be continuing, the
     Collateral Agent shall:

                    (i) commence sales, in the manner described in paragraph (3)
          below, of such portion of the Collateral consisting of U.S. Government
          Securities as may be required to be sold in order to generate proceeds
          sufficient to purchase Common Stock and/or, after an Adjustment Event,
          Reported Securities, as described in the following clause (ii); and

                    (ii) commence purchases, in the manner described in
          paragraph (3) below, of Common Stock and/or, after an Adjustment
          Event, Reported Securities, in an amount sufficient to cause the
          aggregate Pledge Value of the Collateral to be at least equal to the
          Pledge Value Requirement.

               Notwithstanding the foregoing, the Collateral Agent shall
     discontinue sales and purchases pursuant to the preceding clauses (i) and
     (ii), respectively, if at any time a Collateral Event of Default shall have
     occurred and be continuing.   The Collateral Agent shall determine the
     Market Value and the Pledge Value of the Collateral after each purchase of
     Common Stock or Reported Securities pursuant to the preceding clause (ii)
     in order to determine whether the Pledge Value Requirement is met and
     whether a Collateral Event of Default has occurred.   Solely for purposes
     of such calculation, the Market Value of the Common Stock or Reported
     Securities shall be: (A) the most recent sales price as reported in the
     composite transactions for the principal securities exchange on which the
     Common Stock or Reported Securities, as the case may be, are then listed
     or, if such securities are not so listed, the last quoted ask price for
     such securities in the over-the-counter market as reported by The NASDAQ
     National Market or, if not so reported, by the National Quotation Bureau or
     a similar organization; or (B) if higher, in the case of Common Stock, the
     most recent available Closing Price.

               A "Collateral Event of Default" shall mean, at any time, the
                  ---------------------------
     occurrence of any of the following: (A) failure of the aggregate Market
     Value of the Collateral to equal or exceed the Pledge Value Requirement;
     (B) failure of the Market Value of any U.S.

                                       12
<PAGE>

     Government Securities pledged at such time (not including any (i)
     Additional Government Securities or (ii) U.S. Government Securities pledged
     in respect of Cash Delivery Obligations at such time) to have an aggregate
     Market Value of at least 105% of the Market Value of a number of shares of
     Common Stock (or, from and after any Adjustment Event, Reported Securities)
     equal to (x) the Maximum Deliverable Number thereof minus (y) the number
     thereof pledged as Collateral hereunder at such time; or (C) from and after
     any Adjustment Event, failure of the U.S. Government Securities pledged in
     respect of Cash Delivery Obligations to have an aggregate Market Value at
     least equal to 105% of the Cash Delivery Obligations at such time, if, in
     the case of a failure described in this clause (C), such failure shall
     continue to be in effect at 4:00 p.m., New York City time, on the Business
     Day following the day on which telephonic notice in respect thereof shall
     have been given pursuant to paragraph (e)(1) above. For purposes of this
     Agreement, the portion of any pledged U.S. Government Securities that shall
     be deemed to be in respect of Cash Delivery Obligations at any time shall
     be a portion having a Market Value equal to 105% of the Cash Delivery
     Obligations at such time (or, if less, the aggregate Market Value of all
     U.S. Government Securities pledged at such time).

               (3) Collateral sold and Common Stock or shares of Reported
     Securities purchased by the Collateral Agent pursuant to the preceding
     paragraphs (e)(2)(i) and (ii) may be sold and purchased on any securities
     exchange or in any over-the-counter market or in any private purchase
     transaction, and at such price or prices, in each case as the Collateral
     Agent may deem satisfactory.  The Pledgor covenants and agrees that it will
     execute and deliver such documents and take such other action as the
     Collateral Agent deems necessary or advisable in order that any such sales
     and purchases may be made in compliance with law.

          (f) Release of Excess Collateral.  If on any Business Day the
              ----------------------------
Collateral Agent determines that the aggregate Pledge Value of the Pledgor's
Eligible Collateral exceeds the Pledge Value Requirement and no Event of Default
or failure by the Pledgor to meet any of its obligations under Sections 5 or 6
hereof has occurred and is continuing, the Pledgor may obtain the release from
the Lien hereof of any Collateral having an aggregate Pledge Value on such
Business Day less than or equal to such excess, upon delivery to the Collateral
Agent of a written notice from an Authorized Representative of the Pledgor
indicating the items of Collateral to be released.  Such Collateral shall be
released only after the Collateral Agent shall have determined that the
aggregate Pledge Value of all of the Collateral remaining after such release as
determined on such Business Day is at least equal to the Pledge Value
Requirement.

          (g) Delivery of Purchase Agreement Consideration.  On the Exchange
              --------------------------------------------
Date, unless Pledgor shall have exercised its Cash Delivery Option, the
Collateral Agent shall deliver to the Trust Common Stock (or, if an Adjustment
Event shall have occurred, Reported Securities) then held by it hereunder
representing the number of shares of Common Stock (or, if an Adjustment Event
shall have occurred, Reported Securities) then required to be delivered under
the Purchase Agreement.  Upon such delivery, the Trust shall hold such Common
Stock or Reported Securities, as the case may be, absolutely and free from any
claim or right whatsoever.

          (h) Investment of Cash Collateral.  The Collateral Agent shall invest
              -----------------------------
any cash received by it pursuant to Section 6.2 of the Purchase Agreement in
direct obligations of the United States of America maturing on or before the
Exchange Date.

          7.  Income and Voting Rights on Collateral.
              --------------------------------------

          (a) Unless an Event of Default or failure by the Pledgor to meet any
of Pledgor's obligations under Section 5(b) or (c) hereof has occurred and is
continuing, the Pledgor shall be entitled to receive for Pledgor's own account
all dividends, interest and, if any, principal and premium relating to all of
the Collateral, unless the payment thereof to the Pledgor would reduce the
aggregate Pledge Value of the Collateral below the Pledge Value Requirement.
The Collateral Agent agrees to remit to the Pledgor on the Business Day received
or the first Business Day thereafter all such payments received by it.  If an
Event of Default or failure by the Pledgor to meet any of its obligations under
Section 5(b) or (c) hereof has occurred and is continuing, all such payments
made or accrued after and during the continuance of such Event of Default or
failure shall be retained by the Collateral Agent, and any such payments which
are received by the Pledgor shall be received in trust for the benefit of the
Trust, shall be segregated from other funds of the Pledgor and shall forthwith
be paid over to the Collateral Agent.  Any such payments so retained by, or paid
over to, the Collateral Agent shall be held by the Collateral Agent as
Collateral hereunder.  If any such Event of Default or failure is no longer
continuing, then the Collateral Agent shall remit any such payments that are so
retained by, or paid to it, on the first Business Day after the Collateral Agent
shall have received notice from the Trust that such Event of Default or failure
is no longer continuing, unless the payment thereof to the Pledgor would reduce
the aggregate Pledge Value of the Collateral below the Pledge Value Requirement.

          (b) Unless an Event of Default has occurred and is continuing, the
Pledgor shall have the right, from time to time, to vote and to give consents,
ratifications and waivers with respect to the Collateral, and the Collateral
Agent shall promptly deliver to the Pledgor  such proxies, powers of attorney,
consents, ratifications and waivers in respect of any of the Collateral which is
registered in the name of the Collateral Agent or its nominee and shall further
deliver such documents and instruments as shall be specified in a written
request by the Pledgor.

          If an Event of Default shall have occurred and be continuing, the
Collateral Agent shall have the right to the extent permitted by law, and the
Pledgor shall take all such action as may be necessary or appropriate to give
effect to such right, to vote and to give consents, ratifications and waivers,
and take any other action with respect to any or all of the Collateral with the
same force and effect as if the Collateral Agent were the absolute and sole
owner thereof.

          8.  Remedies upon Events of Default.
              -------------------------------

          (a) If any Event of Default shall have occurred and be continuing, the
Collateral Agent may exercise on behalf of the Trust all the rights of a secured
party under the UCC (whether or not in effect in the jurisdiction where such
rights are exercised) and, in addition, without being required to give any
notice, except as herein provided or as may be required by mandatory provisions
of law, shall: (i) deliver all Collateral consisting of Common

                                       14
<PAGE>

Stock or Reported Securities (but not, in either case, in excess of the number
of shares thereof deliverable under the Purchase Agreement at such time) to the
Trust on the date of the notice delivered to the Collateral Agent pursuant to
the last paragraph of Article VII of the Purchase Agreement relating to such
Event of Default (or, in the case of an Event of Default described in clause
(iii), (iv) or (v) of the definition thereof in this Agreement, on the Exchange
Date) (in either case, the "Delivery Date"), whereupon the Trust shall hold such
                            -------------
Common Stock or Reported Securities absolutely free from any claim or right of
whatsoever kind, including any equity or right of redemption of the Pledgor
which may be waived, and the Pledgor, to the extent permitted by law, hereby
specifically waives all rights of redemption, stay or appraisal which Pledgor
has or may have under any law now existing or hereafter adopted; and (ii) if
such delivery shall be insufficient to satisfy in full all of the obligations of
Pledgor under the Purchase Agreement, sell all of the remaining Collateral, or
such lesser portion thereof as may be necessary to generate proceeds sufficient
to satisfy in full all of the obligations of Pledgor under the Purchase
Agreement, at public or private sale or at any broker's board or on any
securities exchange, for cash, upon credit or for future delivery, and at such
price or prices as the Collateral Agent may deem satisfactory. The Pledgor
covenants and agrees to execute and deliver such documents and take such other
action as the Collateral Agent deems necessary or advisable in order that any
such sale may be made in compliance with law. Upon any such sale the Collateral
Agent shall have the right to deliver, assign and transfer to the purchaser
thereof the Collateral so sold. Each purchaser at any such sale shall hold the
Collateral so sold absolutely and free from any claim or right of whatsoever
kind, including any equity or right of redemption of the Pledgor which may be
waived, and the Pledgor, to the extent permitted by law, hereby specifically
waives all rights of redemption, stay or appraisal which Pledgor has or may have
under any law now existing or hereafter adopted. The notice (if any) of such
sale required by Article 9 of the UCC shall (1) in case of a public sale, state
the time and place fixed for such sale, (2) in case of sale at a broker's board
or on a securities exchange, state the board or exchange at which such sale is
to be made and the day on which the Collateral, or the portion thereof so being
sold, will first be offered for sale at such board or exchange, and (3) in the
case of a private sale, state the day after which such sale may be consummated.
Any such public sale shall be held at such time or times within ordinary
business hours and at such place or places as the Collateral Agent may fix in
the notice of such sale. At any such sale the Collateral may be sold in one lot
as an entirety or in separate parcels, as the Collateral Agent may determine.
The Collateral Agent shall not be obligated to make any such sale pursuant to
any such notice. The Collateral Agent may, without notice or publication,
adjourn any public or private sale or cause the same to be adjourned from time
to time by announcement at the time and place fixed for the sale, and such sale
may be made at any time or place to which the same may be so adjourned. In case
of any sale of all or any part of the Collateral on credit or for future
delivery, the Collateral so sold may be retained by the Collateral Agent until
the selling price is paid by the purchaser thereof, but the Collateral Agent
shall not incur any liability in case of the failure of such purchaser to take
up and pay for the Collateral so sold and, in case of any such failure, such
Collateral may again be sold upon like notice. The Collateral Agent, instead of
exercising the power of sale herein conferred upon it, may proceed by a suit or
suits at law or in equity to foreclose the security interests and sell the
Collateral, or any portion thereof, under a judgment or decree of a court or
courts of competent jurisdiction.

          (b) Power of Attorney.  The Collateral Agent is hereby irrevocably
              -----------------
appointed the true and lawful attorney of the Pledgor with full power and
authority, in the name and stead

                                       15
<PAGE>

of the Pledgor, to do all of the following: (i) upon any delivery or sale of all
or any part of any Collateral made either under the power of delivery or sale
given hereunder or under judgment or decree in any judicial proceedings for
foreclosure or otherwise for the enforcement of this Collateral Agreement, to
make all necessary deeds, bills of sale and instruments of assignment, transfer
or conveyance of the property thus delivered or sold; (ii) upon the occurrence
of an Adjustment Event while any shares of Common Stock are Pledged Items, to
take any necessary actions with respect to such shares of Common Stock to cause
the Pledged Items to conform to the requirements of this Agreement following the
occurrence of the Adjustment Event, including, without limitation, the tender of
shares of Common Stock and the sale of property (other than Reported Securities)
received in respect of Common Stock. For such purposes the Collateral Agent may
execute all necessary documents and instruments. This power of attorney shall be
deemed coupled with an interest, and the Pledgor hereby ratifies and confirms
all that its attorneys acting under such power, or such attorneys' successors or
agents, shall lawfully do by virtue of this Collateral Agreement. If so
requested by the Collateral Agent, by the Trustees or by any purchaser of the
Collateral or a portion thereof, the Pledgor shall further ratify and confirm
any such delivery or sale by executing and delivering to the Collateral Agent,
to the Trustees or to such purchaser or purchasers at the expense of the Pledgor
all proper deeds, bills of sale, instruments of assignment, conveyance of
transfer and releases as may be designated in any such request. The Pledgor's
obligations and authorizations hereunder shall not be terminated by operation of
law or the occurrence of any event whatsoever, including the death or disability
of the Pledgor, or the occurrence of any other event.

          (c) Application of Collateral and Proceeds.  In the case of an Event
              --------------------------------------
of Default, the Collateral Agent may proceed to realize upon the security
interest in the Collateral against any one or more of the types of Collateral,
at any one time, as the Collateral Agent shall determine in its sole discretion
subject to the foregoing provisions of this Section 8.  The proceeds of any sale
of, or other realization upon, or other receipt from, any of the Collateral
remaining after delivery to the Trust pursuant to Section 8(a) shall be applied
by the Collateral Agent in the following order of priorities:

      (1) first, to the payment to the Trust of an amount equal to: (A) the
          aggregate Market Value of a number of shares of Common Stock equal to
          (1) the number of shares of Common Stock required to be delivered
          under the Purchase Agreement on the Delivery Date minus (2) the number
          of shares of Common Stock delivered by the Collateral Agent to the
          Trust on the Delivery Date as described above; or (B) from and after
          an Adjustment Event, the sum of (1) the Cash Delivery Obligations on
          the Delivery Date and (2) the aggregate Market Value on the Delivery
          Date of a number of Reported Securities (and, if applicable, shares of
          Common Stock) equal to (x) the number thereof required to be delivered
          on the Delivery Date under Section 6.2 of the Purchase Agreement minus
          (y) the number thereof delivered by the Collateral Agent to the Trust
          on the Delivery Date as described above; or (C) if the Pledgor shall
          have exercised its Cash Delivery Option, the amount of cash required
          to be delivered under Section 1.3(d) of the Purchase Agreement minus
          the amount of cash so delivered; and (D) if the Pledgor shall have
          extended the Exchange Date pursuant to Section 1.3(f) of the Purchase
          Agreement, the amount of cash required to be delivered under said
          Section 1.3(f)

                                       16
<PAGE>

          (or, if the Pledgor shall have accelerated the Exchange Date pursuant
          to Section 1.3(g) thereof, the amount of cash deliverable pursuant to
          said Section 1.3(g));

      (2) second, to the payment to the Collateral Agent of the expenses of such
          sale or other realization, including reasonable compensation to the
          Collateral Agent and its agents and counsel, and all expenses,
          liabilities and advances incurred or made by the Collateral Agent in
          connection therewith, including brokerage fees in connection with the
          sale by the Collateral Agent of any Pledged Item; and

      (3) finally, if all of the obligations of the Pledgor hereunder and under
          the Purchase Agreement have been fully discharged or sufficient funds
          have been set aside by the Collateral Agent at the request of the
          Pledgor for the discharge thereof, any remaining proceeds shall be
          released to the Pledgor.

          9.  The Collateral Agent.
              --------------------

          The Collateral Agent accepts its duties and responsibilities hereunder
as agent for the Trust, on and subject to the following terms and conditions:

          (a) Performance of Duties.  The Collateral Agent undertakes to perform
              ---------------------
such duties and only such duties as are expressly set forth herein and, beyond
the exercise of reasonable care in the performance of such duties, no implied
covenants or obligations shall be read into this Collateral Agreement against
the Collateral Agent.  No provision hereof shall be construed to relieve the
Collateral Agent from liability for its own grossly negligent action, grossly
negligent failure to act or its own willful misconduct, subject to the
following:

               (1) The Collateral Agent may consult with counsel, and the advice
     or opinion of such counsel shall be full and complete authorization and
     protection in respect of an action taken or suffered hereunder in good
     faith and in accordance with such advice or opinion of counsel.

               (2) The Collateral Agent shall not be liable with respect to any
     action taken, suffered or omitted by it in good faith (i) reasonably
     believed by it to be authorized or within the discretion or rights or
     powers conferred on it by this Collateral Agreement or (ii) in accordance
     with any direction or request of the Trustees.

               (3) The Collateral Agent shall not be liable for any error of
     judgment made in good faith by any of its officers, unless the Collateral
     Agent was grossly negligent in ascertaining the pertinent facts.

               (4) In the absence of bad faith on its part, the Collateral Agent
     may conclusively rely, as to the truth of the statements and the
     correctness of the opinions expressed therein, upon any note, notice,
     resolution, consent, certificate, affidavit, letter, telegram, teletype
     message, statement, order or other document believed by it to be genuine
     and correct and to have been signed or sent by the proper Person or
     Persons.

               (5) No provision of this Collateral Agreement shall require the
     Collateral Agent to expend or risk its own funds or otherwise incur any
     financial liability

                                       17
<PAGE>

     in the performance of any of its duties hereunder, or in the exercise of
     any of its rights or powers, if it shall have reasonable grounds for
     believing that repayment of such funds or adequate indemnity against such
     risk or liability is not reasonably assured to it.

               (6) The Collateral Agent may perform any duties hereunder either
     directly or by or through agents or attorneys, and the Collateral Agent
     shall not be responsible for any misconduct or negligence on the part of
     any agent or attorney appointed with due care by it hereunder.  In
     furtherance thereof, any subsidiary owned or controlled by the Collateral
     Agent, or its successors, as agent for the Collateral Agent, may perform
     any or all of the duties of the Collateral Agent relating to the valuation
     of securities and other instruments constituting Collateral hereunder.

               (7) In no event shall the Collateral Agent be personally liable
     for any taxes or other governmental charges imposed upon or in respect of
     (i) the collateral or (ii) the income or other distributions thereon.

               (8) Unless and until the Collateral Agent shall have received
     notice from the Pledgor, or unless and until a Responsible Officer of the
     Collateral Agent shall have actual knowledge to the contrary, the
     Collateral Agent shall be entitled to deem and treat all Collateral
     delivered to it hereunder as Eligible Collateral hereunder, provided that
     the Collateral Agent has carried out the duties specified in Section 6 with
     respect to such Collateral at the time of delivery thereof.

          The Collateral Agent shall not be responsible for the correctness of
the recitals and statements herein which are made by the Pledgor or for any
statement or certificate delivered by the Pledgor pursuant hereto.  Except as
specifically provided herein, the Collateral Agent shall not be responsible for
the validity, sufficiency, collectibility or marketability of any Collateral
given to or held by it hereunder or for the validity or sufficiency of the
Purchase Agreement or the Lien on the Collateral purported to be created hereby.

          (b) Knowledge.  The Collateral Agent shall not be deemed to have
              ---------
knowledge of any Event of Default (except a Collateral Event of Default), unless
and until a Responsible Officer of the Collateral Agent shall have actual
knowledge thereof or shall have received written notice thereof.

          (c) Merger.  Any corporation or association into which the Collateral
              ------
Agent may be converted or merged, or with which it may be consolidated, or to
which it may sell or transfer its agency business and assets as a whole or
substantially as a whole, or any corporation or association resulting from any
such conversion, sale, merger, consolidation or transfer to which it is a party,
shall, subject to the prior written consent of the Trust, be and become a
successor Collateral Agent hereunder and vested with all of the title to the
Collateral and all of the powers, discretions, immunities, privileges and other
matters as was its predecessor without, except as provided above, the execution
or filing of any instrument or any further act, deed or conveyance on the part
of any of the parties hereto, anything herein to the contrary notwithstanding.

                                       18
<PAGE>

          (d) Resignation.  The Collateral Agent and any successor Collateral
              -----------
Agent may at any time resign by giving thirty days' written notice by registered
or certified mail to the Pledgor and notice to the Trust in accordance with the
provisions of Section 10(d) hereof.  Such resignation shall take effect upon the
appointment of a successor Collateral Agent by the Trust.

          (e) Removal.  The Collateral Agent may be removed at any time by an
              -------
instrument or concurrent instruments in writing delivered to the Collateral
Agent and to the Pledgor and signed by the Trust.

          (f) Appointment of Successor.  (1)  If the Collateral Agent hereunder
              ------------------------
shall resign or be removed, or be dissolved or shall be in the course of
dissolution or liquidation or otherwise become incapable of action hereunder, or
if it shall be taken under the control of any public officer or officers or of a
receiver appointed by a court, a successor may be appointed by the Trust by an
instrument or concurrent instruments in writing signed by the Trust or by its
attorneys in fact fully authorized a copy of such instrument or concurrent
instruments shall be sent by registered mail to the Pledgor.

          (2) Every such temporary or permanent successor Collateral Agent
appointed pursuant to the provisions hereof shall be a trust company or bank in
good standing, having a reported capital and surplus of not less than
$100,000,000 and capable of holding the Collateral in the State of New York, if
there be such an institution willing, qualified and able to accept the duties of
the Collateral Agent hereunder upon customary terms.

          (g) Acceptance by Successor.  Every temporary or permanent successor
              -----------------------
Collateral Agent appointed hereunder shall execute, acknowledge and deliver to
its predecessor and also to the Pledgor an instrument in writing accepting such
appointment hereunder, whereupon such successor, without any further act, deed
or conveyance, shall become fully vested with all the estates, properties,
rights, powers, duties and obligations of its predecessors.  Such predecessor
shall, nevertheless, on the written request of its successor or the Pledgor,
execute and deliver an instrument transferring to such successor all the
estates, properties, rights and powers of such predecessor hereunder.  Every
predecessor Collateral Agent shall deliver all Collateral held by it as the
Collateral Agent hereunder to its successor.  Should any instrument in writing
from the Pledgor be required by a successor Collateral Agent for more fully and
certainly vesting in such successor the estates, properties, rights, powers,
duties and obligations hereby vested or intended to be vested in the
predecessor, any and all such instruments in writing shall, at the request of
the temporary or permanent successor Collateral Agent, be forthwith executed,
acknowledged and delivered by the Pledgor.

          10.  Miscellaneous.
               -------------

          (a) Benefit of Agreement; Successors and Assigns.  Whenever any of the

successors and assigns of such party.  All the covenants and agreements herein
contained by or on behalf of the Pledgor and the Collateral Agent shall bind,

expressed or not, and shall be enforceable by and inure to the benefit of the
Trust and its successors and assigns.  [This Agreement will be binding on and
legally enforceable against the Pledgor, despite the death or legal incapacity
of any settlor or beneficiary thereof.]

              -------------
construed in accordance with and governed by the laws of the State of New York;
provided that as to Pledged Items located in any jurisdiction other than the

for the payment of such Additional Expense.

          (d)  Salomon Smith Barney may contest in good faith the reasonableness
of any Additional Expense and the parties shall attempt to resolve amicably the

date hereunder with respect to such Additional Expense, subject to the first
sentence of paragraph (b) of this Section 3, Salomon Smith Barney shall pay the
amount of such Additional Expense, subject to later adjustment and credit if
such dispute is resolved in favor of Salomon Smith Barney.

     -----

          WHEREAS the Trust is a statutory business trust organized under the
Business Trust Act of the State of Delaware pursuant to a Declaration of Trust
dated as of April 22, 1999, as amended and restated as of July 14, 1999, and as
further amended and restated as of              , 1999 (the "Trust Agreement");
                                                             ---------------
and

          WHEREAS, Salomon Smith Barney, as sponsor under the Trust Agreement,
desires to make provision for the payment of certain indemnification expenses of
the Trust.

          NOW, THEREFORE, in consideration of the premises and the mutual
covenants contained in this Agreement, the parties agree as follows:

          1.    Definitions.  Capitalized terms used herein and not defined
herein shall have the meanings ascribed thereto in the Trust Agreement.

          2.    Agreement to Pay Expenses.  Salomon Smith Barney agrees to pay
to the Trust, and hold the Trust harmless from, any expenses of the Trust
arising under Sections 2.2(e) and 6.6 of the Administration Agreement, Section
15 of the Custodian Agreement, Section 5.4(b) of the Paying Agent Agreement and
Section 7.6 of the Trust Agreement (collectively, together with any amounts paid

                                            ------------------------
to paragraph 4 hereof, payment hereunder by Salomon Smith Barney shall be made
in New York Clearing House funds no later than five Business Days after the
receipt by Salomon Smith Barney, pursuant to paragraph 3 hereof, of written
notice of any claim for Indemnification Expenses.

          3.    Notice of Receipt of Claim.  The Trust shall give notice to, or
cause notice to be given to, Salomon Smith Barney in writing of any claim for
Indemnification Expenses or any threatened claim for Indemnification Expenses
immediately upon the Trust acquiring knowledge thereof.  Such written notice
shall be accompanied by any demand, bill, invoice or other communication
received from any third party claimant (a "Claimant") in respect of such
                                           --------
Indemnification Expense.

          4.    Right to Contest.  The Trust agrees that Salomon Smith Barney
may, and Salomon Smith Barney is authorized on behalf of the Trust to, contest
in good faith with any Claimant any amount contained in any claim for
Indemnification Expense, provided, that if, within such time period as Salomon
Smith Barney shall determine to be reasonable, Salomon Smith Barney and such
Claimant are unable to resolve amicably any disagreement regarding such claim
for Indemnification Expense, Salomon Smith Barney shall retain counsel
reasonably satisfactory to the Trustees to represent the Trustees in any
resulting proceeding and shall pay the fees and disbursements of such counsel
related to such proceeding.  Notwithstanding any other provision herein, it is
understood that (a) Salomon Smith Barney shall not, in respect of the legal
<PAGE>

expenses of any indemnified party in connection with any proceeding or related
proceedings in the same jurisdiction, be liable for the fees and expenses of
more than one separate firm (in addition to any local counsel), and (b) Salomon
Smith Barney shall not be liable for any settlement of any proceeding effected
without its written consent, but if settled with such consent or if there be a
final judgment for the Claimant, Salomon Smith Barney agrees to indemnify the
Trust from and against any loss or liability by reason of such settlement or
judgment.

          5.    Statements and Reports.  The Trust shall collect and safekeep
all demands, bills, invoices or other written communications received from third
parties in connection with any claim for Indemnification Expenses and shall
prepare and maintain adequate books and records showing all receipts and
disbursements of funds in connection therewith.  Salomon Smith Barney shall have
the right to inspect and to copy, at its expense, all such documents, books and
records at all reasonable times and from time to time during the term of this
Agreement.

          6.    Term of Contract.  This Agreement shall continue in effect until
the termination of the Trust in accordance with Section 8.3 of the Trust
Agreement.

          7.    No Assignment.  No party to this Agreement may assign its rights
or delegate its duties hereunder without the prior written consent of the other
parties, except that the Trust may delegate any and all duties hereunder to the
Administrator to the extent permitted by law.

          8.    Entire Agreement.  This Agreement contains the entire agreement
among the parties with respect to the matters contained herein and supersedes
all prior agreements or understandings.  No amendment or modification of this
Agreement shall be valid unless the amendment or modification is in writing and
is signed by all the parties to this Agreement.

or consents given by any party under this Agreement shall be in writing and
shall be delivered in person or by telecopy or other facsimile communication or

          (h)  A Certificate of Good Standing for the Trust, dated August 5,
1999, obtained from the Secretary of State.

          Initially capitalized terms used herein and not otherwise defined are
used as defined in the Trust Agreement.

          For purposes of this opinion, we have not reviewed any documents other
than the documents listed above, and we have assumed that there exists no
provision in any document that we have not reviewed that bears upon or is
inconsistent with the opinions stated herein.  We have conducted no independent
factual investigation of our own but rather have relied solely upon the
foregoing documents, the statements and information set forth therein and the
additional matters recited or assumed herein, all of which we have assumed to be
true, complete and accurate in all material respects.

          With respect to all documents examined by us, we have assumed that (i)
all signatures on documents examined by us are genuine, (ii) all documents
submitted to us as originals are authentic, and (iii) all documents submitted to
us as copies conform with the original copies of those documents.

          For purposes of this opinion, we have assumed (i) that the Trust
Agreement and the Certificate of Trust constitute the entire agreement among the
parties thereto with respect to the subject matter thereof, including with
respect to the creation, operation and termination of the Trust, and that the
Trust Agreement and the Certificate of Trust are in full force and effect and
have not been amended, (ii) except to the extent provided in paragraph 1 below,
the due creation or due organization or due formation, as the case may be, and
valid existence in good standing of each party to the documents examined by us
under the laws of the jurisdiction governing its creation, organization or
formation, (iii) that at least one of the Trustees is a resident of the State of
Delaware, (iv) the legal capacity of natural persons who are parties to the
documents examined by us, (v) except as provided in paragraphs 2 and 4 below,
that each of the parties to the documents examined by us has the power and
authority to execute and deliver, and to perform its obligations under, such
documents, (vi) except as provided in paragraph 5 below, the due authorization,
execution and delivery by all parties thereto of all documents examined by us,
(vii) the receipt by each Person to whom a DECS is to be issued by the Trust
(collectively, the "DECS Holders") of an interest in the DECS Certificate
                    ------------
(substantially in the form of Exhibit A to the Trust Agreement) and the payment
for the DECS acquired by it, in accordance with the

Trust Agreement and the Registration Statement, and (viii) that the DECS are
issued and sold to the DECS Holders in accordance with the Trust Agreement and
the Registration Statement. We have not participated in the preparation of the
Registration Statement and assume no responsibility for its contents.

          This opinion is limited to the laws of the State of Delaware
(excluding the securities laws of the State of Delaware), and we have not
considered and express no opinions on the laws of any other jurisdiction,
including federal laws and rules and regulations relating thereto.  Our opinions
are rendered only with respect to Delaware laws and rules, regulations and
orders thereunder that are currently in effect.

          Based upon the foregoing, and upon our examination of such questions
of law and statutes of the State of Delaware as we have considered necessary or
appropriate, and subject to the assumptions, qualifications, limitations and
exceptions set forth herein, we are of the opinion that:

          1.  The Trust has been duly created and is validly existing in good
standing as a business trust under the Delaware Business Trust Act, 12 Del. C.
                                                                       -------
(S) 3801, et seq. (the "Business Trust Act"), and all filings required under the
          -- ---        ------------------
laws of the State of Delaware with respect to the creation and valid existence
of the Trust as a business trust have been made.

          2.  When issued and sold, the DECS will represent valid and, subject
to the qualifications set forth in paragraph 3 below, fully paid and
nonassessable undivided beneficial interests in the assets of the Trust.

          3.  The DECS Holders, as beneficial owners of the Trust, will be
entitled to the same limitation of personal liability extended to stockholders
of private corporations for profit organized under the General Corporation Law
of the State of Delaware. We note that the DECS Holders may be obligated to make
payments as set forth in the Declaration.

          We consent to the filing of this opinion with the SEC as an exhibit to
the Registration Statement.  In addition, we hereby consent to the use of our
name under the heading "Legal Matters" in the Prospectus.  In giving the
foregoing consent, we do not thereby admit that we come within the category of
Persons whose consent is required under Section 7 of the Securities Act of 1933,
as amended, or the rules and regulations of the SEC thereunder.  Except as
stated above, without our prior written consent, this opinion may not be
furnished or quoted to, or relied upon by, any other Person for any purpose.

                                    Very truly yours,

                            SUBSCRIPTION AGREEMENT

          This SUBSCRIPTION AGREEMENT dated as of the 4th day of August, 1999,
is entered into between DECS Trust V, a statutory business trust organized under
the Business Trust Act of the State of Delaware (such trust and the trustees
thereof acting in their capacity as such being referred to herein as the
"Trust"), and Salomon Smith Barney Inc. (the "Purchaser").
 -----                                        ---------

          WHEREAS, the Purchaser has heretofore transferred to the Trust the
amount of $100.00 (the "Purchase Price") for the purpose and with the intent of
                        --------------
purchasing one DECS (the "Subscription DECS"), representing an undivided
beneficial interest in the Trust; and

          WHEREAS, the Trust wishes to transfer to the Purchaser, in
consideration of the Purchase Price, the Subscription DECS.

          NOW THEREFORE, the parties hereto agree as follows:

          1.  Purchase and Sale of the DECS.
              -----------------------------

          1.1.  Sale and Issuance of DECS.  Subject to the terms and conditions
                -------------------------
of this Agreement, the Trust agrees to sell to the Purchaser in consideration of
the Purchaser's delivery to the Trust of the Purchase Price, and the Purchaser
agrees to purchase from the Trust, one DECS (the "Subscription DECS"),
                                                  -----------------
representing an undivided beneficial interest in the Trust.

          1.2.  Closing.  (a)  The closing of the purchase and sale of the
                -------
Subscription DECS shall take place at the offices of Cleary, Gottlieb, Steen &
Hamilton, One Liberty Plaza, New York, New York 10006 at                , on
, 1999, or at such other time (the "Closing Date") and place as the Trust and
                                    ------------
the Purchaser mutually agree upon.  At or after the Closing Date, the Trust
shall deliver to the Purchaser a certificate representing the Subscription DECS,
registered in the name of the Purchaser or its nominee.

          (b) The Trust hereby acknowledges Purchaser's delivery to the Trust of
the Purchase Price on April 23, 1999.

          2.  Representations, Warranties and Covenants of the Purchaser.  The
              ----------------------------------------------------------
Purchaser hereby represents and warrants to, and covenants for the benefit of,
the Trust that:

          2.1.  Purchase Entirely for Own Account.  This Agreement is made by
                ---------------------------------
the Trust with the Purchaser in reliance upon the Purchaser's representation to
the Trust, which by the Purchaser's execution of this Agreement the Purchaser
hereby confirms, that the Purchaser is acquiring the Subscription DECS for
investment for the Purchaser's own account, and not as a nominee or agent and
not with a view to the resale or distribution by the Purchaser of such
Subscription DECS, and that the Purchaser has no present intention of selling,
granting any participation in, or otherwise distributing the Subscription DECS,
in either case in violation of any securities registration requirement under
applicable law, but subject nevertheless to any requirement of law that the
disposition of its property shall at all times be within its control.  By
<PAGE>

executing this Agreement, the Purchaser further represents that the Purchaser
does not have any contract, undertaking, agreement or arrangement with any
person to sell, transfer or grant participation to such person, or to any third
person, with respect to the Subscription DECS.

          2.2.  Investment Experience.  The Purchaser acknowledges that it can
                ---------------------
bear the economic risk of the investment for an indefinite period of time and
has such knowledge and experience in financial and business matters (and
particularly in the business in which the Trust operates) as to be capable of
evaluating the merits and risks of the investment in the Subscription DECS.  The
Purchaser is an "accredited investor" as defined in Rule 501(a) of Regulation D
under the Securities Act of 1933 (the "Act").
                                       ---

          2.3.  Restricted Securities.  The Purchaser understands that the
                ---------------------
Subscription DECS are characterized as "restricted securities" under the United
States securities laws inasmuch as they are being acquired from the Trust in a
transaction not involving a public offering and that under such laws and
applicable regulations such Subscription DECS may be resold without registration
under the Act only in certain circumstances.  In this connection, the Purchaser
represents that it understands the resale limitations imposed by the Act and is
generally familiar with the existing resale limitations imposed by Rule 144
under the Act.

          2.4.  Further Limitations on Disposition.  The Purchaser further
                ----------------------------------
agrees not to make any disposition directly or indirectly of all or any portion
of the Subscription DECS unless and until:

          (a) There is then in effect a registration statement under the Act
          covering such proposed disposition and such disposition is made in
          accordance with such registration statement; or

          (b) The Purchaser shall have furnished the Trust with an opinion of
          counsel, reasonably satisfactory to the Trust, that such disposition
          will not require registration of such Subscription DECS under the Act.

          (c) Notwithstanding the provisions of subsections (a) and (b) above,
          no such registration statement or opinion of counsel shall be
          necessary for a transfer by the Purchaser to any affiliate of the
          Purchaser, if the transferee agrees in writing to be subject to the
          terms hereof to the same extent as if it were the original Purchaser
          hereunder.

          2.5.  Legends.  It is understood that the certificate evidencing the
                -------
Subscription DECS may bear either or both of the following legends:

          (a) "These securities have not been registered under the Securities
          Act of 1933.  They may not be sold, offered for sale, pledged or
          hypothecated in the absence of a registration statement in effect with
          respect to the securities under


                                       2
<PAGE>

          such Act or an opinion of counsel reasonably satisfactory to the
          Trustee of DECS Trust V that such registration is not required."

          (b) Any legend required by the laws of any other applicable
          jurisdiction.

          The Purchaser and the Trust agree that the legend contained in
paragraph (a) above shall be removed at a holder's request when it is no longer
necessary to ensure compliance with federal securities laws.

          2.6.  Amendment to Declaration of Trust; Split of DECS.  The Purchaser
                ------------------------------------------------
consents to (a) the execution and delivery by the Trustees and Salomon Smith
Barney Inc., as sponsor of the Trust, of an Amended and Restated Declaration of
Trust substantially in the form attached hereto and (b) the split of the
Subscription DECS subsequent to the determination of the public offering price
per DECS and related underwriting discount for the DECS to be sold to the
Underwriter (as defined in such Amended and Restated Declaration of Trust) but
prior to the sale of the DECS to the Underwriters into a greater number of DECS
so that immediately following such split the value of the Subscription DECS will
equal the aforesaid public offering price per DECS.

          2.7.  Counterparts.  This Agreement may be executed in several
                ------------
counterparts, each of which shall be an original and all of which shall
constitute but one and the same instrument.

          2.8.  Governing Law.  This Agreement shall be governed by and
                -------------
construed and interpreted in accordance with the laws of the State of New York
applicable to agreements made and to be performed wholly within such state.

                                       3
