of such action is made upon such Security Certificate.

     (e) The Company may set any day as a record date for the purpose of
determining the Holders of Outstanding Securities entitled to give, make or take
any request, demand, authorization, direction, notice, consent, waiver or other
action provided or permitted by this Agreement to be given, made or taken by
Holders of Securities. If any record date is set pursuant to this paragraph, the
Holders of Outstanding Securities on such record date, and no other Holders,
shall be entitled to take the relevant action, whether or not such Holders
remain Holders after such record date; provided that no such action shall be
effective hereunder unless taken on or prior to the applicable Expiration Date
by Holders of the requisite number of Outstanding Securities on such record
date. Nothing in this paragraph shall be construed to prevent the Company from
setting a new record date for any action for which a record date has previously
been set pursuant to this paragraph (whereupon the record date previously set
shall automatically and with no action by any Person be canceled and of no
effect), and nothing in this paragraph shall be construed to render ineffective
any action taken by Holders of the requisite number of Outstanding Securities on
the date such action is taken. Promptly after any record date is set pursuant to
this paragraph, the Company, at its own expense, shall cause notice of such
record date, the proposed action by Holders and the applicable Expiration Date
to be given to the Agent in writing and to each Holder of Securities in the
manner set forth in Section 1.06.

With respect to any record date set pursuant to this Section, the Company may
designate any date as the "Expiration Date" and from time to time may change the
Expiration Date to any earlier or later day; provided that no such change shall
be effective unless notice of the proposed new Expiration Date is given to the
Agent in writing, and to each Holder of Securities in the manner set forth in
Section 1.06, on or prior to the existing Expiration Date. If an Expiration Date
is not designated with respect to any record date set pursuant to this Section,
the Company shall be deemed to have initially designated the 180th day after
such record date as the Expiration Date with respect thereto, subject to its
right to change the Expiration Date as provided in this paragraph.
Notwithstanding the foregoing, no Expiration Date shall be later than the 180th
day after the applicable record date.

     Section 1.05. Notices, etc., to Agent and the Company. Any request, demand,
authorization, direction, notice, consent, waiver or Act of Holders or other
document provided or permitted by this Agreement to be made upon, given or
furnished to, or filed with,

                                       -6-



         (1) the Agent by any Holder or by the Company shall be sufficient for
     every purpose hereunder (unless otherwise herein expressly provided) if
     made, given, furnished or filed in writing and personally delivered or
     mailed, first class postage prepaid, to the Agent at _______________,
     Attention: Stock Transfer Department, or at any other address previously
     furnished in writing by the Agent to the Holders and the Company, or

         (2) the Company by the Agent or by any Holder shall be sufficient for
     every purpose hereunder (unless otherwise herein expressly provided) if
     made, given, furnished or filed in writing and personally delivered or
     mailed, first-class postage prepaid, to the Company at 5900 Princess Garden
     Parkway, 7th Floor, Lanham, MD 20706-2969, Attention: Linda J. Eckard
     Vilardo, or at any other address previously furnished in writing to the
     Agent by the Company.

     Section 1.06. Notice to Holders; Waiver. Where this Agreement provides for
notice to Holders of any event, such notice shall be sufficiently given (unless
otherwise herein expressly provided) if in writing and mailed, first class
postage prepaid, to each Holder affected by such event, at his address as it
appears in the Security Register, not later than the latest date, and not
earlier than the earliest date, prescribed for the giving of such notice. In any
case where notice to Holders is given by mail, neither the failure to mail such
notice, nor any defect in any notice so mailed to any particular Holder shall
affect the sufficiency of such notice with respect to other Holders.

     Where this Agreement provides for notice in any manner, such notice may be
waived in writing by the Person entitled to receive such notice, either before
or after the event, and such waiver shall be the equivalent of such notice.
Waivers of notice by Holders shall be filed with the Agent, but such filing
shall not be a condition precedent to the validity of any action taken in
reliance upon such waiver.

     In case by reason of the suspension of regular mail service or by reason of
any other cause it shall be impracticable to give such notice by mail, then such
notification as shall be made with the approval of the Agent shall constitute a
sufficient notification for every purpose hereunder.

     Section 1.07. Effect of Headings and Table of Contents. The Article and
Section headings herein and the Table of Contents are for convenience only and
shall not affect the construction hereof.

     Section 1.08. Successors and Assigns. All covenants and agreements in this
Agreement by the Company shall bind its successors and assigns, whether so
expressed or not.

     Section 1.09. Separability Clause. In case any provision in this Agreement
or in the Securities shall be invalid, illegal or unenforceable, the validity,
legality and enforceability of the remaining provisions hereof and thereof shall
not in any way be affected or impaired thereby.

     Section 1.10. Benefits of Agreement. Nothing in this Agreement or in the
Securities, express or implied, shall give to any Person, other than the parties
hereto and their successors hereunder and the Holders, any benefits or any legal
or equitable right, remedy or claim under this Agreement. The Holders from time
to time shall be beneficiaries of this Agreement and shall be bound by all of
the terms and conditions hereof and of the Securities evidenced by their
Security Certificates by their acceptance of delivery thereof.

     Section 1.11. Governing Law. This Agreement and the Securities shall be
governed by and construed in accordance with the laws of the State of New York.

     Section 1.12. Legal Holidays. In any case where any Payment Date, any Early
Settlement Date or the Final Settlement Date shall not be a Business Day, then
(notwithstanding any other provision of this Agreement or of the Securities)
payment in respect of distributions on Pledged Securities or Contract Fees shall
not be made, Purchase Contracts shall not be performed and Early Settlement
shall not be effected on such date, but such payments shall be made, or the
Purchase Contracts shall be performed or Early Settlement effected, as
applicable, on the next succeeding Business Day with the same force and effect
as if made on such Payment Date, Early Settlement Date or Final Settlement Date,
as the case may be; provided, that no interest shall accrue or be payable by the
Company or any Holder

                                       -7-



for the period from and after any such Payment Date, Early Settlement Date or
Final Settlement Date, as the case may be.

     Section 1.13. Counterparts. This Agreement may be executed in any number of
counterparts, each of which, when so executed, shall be deemed an original, but
all such counterparts shall together constitute one and the same instrument.

     Section 1.14. Inspection of Agreement. A copy of this Agreement shall be
available at all reasonable times at the Corporate Trust Office for inspection
by any Holder.

                                   ARTICLE TWO
                           SECURITY CERTIFICATE FORMS

     Section 2.01. Forms of Security Certificates Generally. The Security
Certificates (including the form of Purchase Contracts forming part of the
Securities evidenced thereby) shall be in substantially the form set forth in
Exhibit A hereto, with such letters, numbers or other marks of identification or
designation and such legends or endorsements printed, lithographed or engraved
thereon as may be required by the rules of any securities exchange on which the
Securities are listed or Depositary therefor, or as may, consistently herewith,
be determined by the officers of the Company executing such Security
Certificates, as evidenced by their execution of the Security Certificates.

     The definitive Security Certificates shall be printed, lithographed or
engraved on steel engraved borders or may be produced in any other manner, all
as determined by the officers of the Company executing the Security
Certificates, consistent with the provisions of this Agreement, as evidenced by
their execution thereof.

     Every Global Security Certificate authenticated, executed on behalf of the
Holders and delivered hereunder shall bear a legend in substantially the
following form:

         THIS SECURITY CERTIFICATE IS A GLOBAL SECURITY CERTIFICATE WITHIN THE
         MEANING OF THE PURCHASE CONTRACT AGREEMENT HEREINAFTER REFERRED TO AND
         IS REGISTERED IN THE NAME OF A DEPOSITARY OR A NOMINEE THEREOF. THIS
         SECURITY CERTIFICATE MAY NOT BE EXCHANGED IN WHOLE OR IN PART FOR A
         SECURITY CERTIFICATE REGISTERED, AND NO TRANSFER OF THIS SECURITY
         CERTIFICATE IN WHOLE OR IN PART MAY BE REGISTERED, IN THE NAME OF ANY
         PERSON OTHER THAN SUCH DEPOSITARY OR A NOMINEE THEREOF. EXCEPT IN THE
         LIMITED CIRCUMSTANCES DESCRIBED IN THE PURCHASE CONTRACT AGREEMENT.

     Section 2.02. Form of Agent's Certificate of Authentication. The form of
the Agent's certificate of authentication of the Securities shall be in
substantially the form set forth on the form of the Security Certificates.

                                  ARTICLE THREE
                                 THE SECURITIES

     Section 3.01. Title and Terms; Denominations. The aggregate number of
Securities evidenced by Security Certificates authenticated, executed on behalf
of the Holders and delivered hereunder is limited to _________ (subject to
increase up to a maximum of _____________ to the extent the overallotment option
of the underwriters under the Underwriting Agreement is exercised), except for
Security Certificates authenticated, executed and delivered upon registration of
transfer of, in exchange for, or in lieu of, other Security Certificates
pursuant to Section 3.04, 3.05, 3.06, 5.09 or 8.05.

     The Security Certificates shall be issuable only in registered form and
only in denominations of a single Security and any integral multiple thereof.

     Section 3.02. Rights and Obligations Evidenced by the Security
Certificates. Each Security Certificate shall evidence the number of Securities
specified therein, with each such Security representing the ownership by the
Holder thereof of Pledged Securities with a principal amount or liquidation
preference equal to the Stated Amount, subject to

                                       -8-



the Pledge of such Pledged Securities by such Holder pursuant to the Pledge
Agreement, and the rights and obligations of the Holder under one Purchase
Contract. Prior to the purchase, if any, of shares of Common Stock under the
Purchase Contracts, the Securities shall not entitle the Holders to any of the
rights of a holder of shares of Common Stock, including, without limitation, the
right to vote or receive any dividends or other payments or to consent or to
receive notice as stockholders in respect of the meetings of stockholders or for
the election of directors of the Company or for any other matter, or any other
rights whatsoever as stockholders of the Company, except to the extent otherwise
expressly provided in this Agreement.

     Section 3.03. Execution, Authentication, Delivery and Dating. Upon the
execution and delivery of this Agreement, and at any time and from time to time
thereafter, the Company may deliver Security Certificates executed by the
Company to the Agent for authentication, execution on behalf of the Holders and
delivery, together with its Issuer Order for authentication of such Security
Certificates, and the Agent in accordance with such Issuer Order shall
authenticate, execute on behalf of the Holder and deliver such Security
Certificates.

     The Security Certificates shall be executed on behalf of the Company by its
Chairperson of the Board, its Vice Chairperson of the Board, its President or
one of its Vice Presidents, under its corporate seal reproduced thereon attested
by its Secretary or one of its Assistant Secretaries. The signature of any of
these officers on the Security Certificates may be manual or facsimile.

     Security Certificates bearing the manual or facsimile signatures of
individuals who were at any time the proper officers of the Company shall bind
the Company, notwithstanding that such individuals or any of them have ceased to
hold such offices prior to the authentication and delivery of such Security
Certificates or did not hold such offices at the date of such Security
Certificates.

     No Purchase Contract underlying a Security evidenced by a Security
Certificate shall be valid until such Security Certificate has been executed on
behalf of the Holder by the manual signature of an authorized signatory of the
Agent, as such Holder's attorney-in-fact. Such signature by an authorized
signatory of the Agent shall be conclusive evidence that the Holder of such
Security Certificate has entered into the Purchase Contracts underlying the
Securities evidenced by such Security Certificate.

     Each Security Certificate shall be dated the date of its authentication.

     No Security Certificate shall be entitled to any benefit under this
Agreement or be valid or obligatory for any purpose unless there appears on such
Security Certificate a certificate of authentication substantially in the form
provided for herein executed by an authorized signatory of the Agent by manual
signature, and such certificate upon any Security Certificate shall be
conclusive evidence, and the only evidence, that such Security Certificate has
been duly authenticated and delivered hereunder.

     Section 3.04. Temporary Security Certificates. Pending the preparation of
definitive Security Certificates, the Company shall execute and deliver to the
Agent, and the Agent shall authenticate, execute on behalf of the Holders, and
deliver, in lieu of such definitive Security Certificates, temporary Security
Certificates which are in substantially the form set forth in Exhibit A hereto,
with such letters, numbers or other marks of identification or designation and
such legends or endorsements printed, lithographed or engraved thereon as may be
required by the rules of any securities exchange on which the Securities are
listed, or as may, consistently herewith, be determined by the officers of the
Company executing such Security Certificates, as evidenced by their execution of
the Security Certificates.

     If temporary Security Certificates are issued, the Company will cause
definitive Security Certificates to be prepared without unreasonable delay.
After the preparation of definitive Security Certificates, the temporary
Security Certificates shall be exchangeable for definitive Security Certificates
upon surrender of the temporary Security Certificates at the Corporate Trust
Office, at the expense of the Company and without charge to the Holder. Upon
surrender for cancellation of any one or more temporary Security Certificates,
the Company shall execute and deliver to the Agent, and the Agent shall
authenticate, execute on behalf of the Holder, and deliver in exchange therefor,
one or more definitive Security Certificates of authorized denominations and
evidencing a like number of Securities as the temporary Security Certificate or
Security Certificates so surrendered. Until so exchanged, the temporary Security
Certificates shall

                                       -9-



in all respects evidence the same benefits and the same obligations with respect
to the Securities evidenced thereby as definitive Security Certificates.

     Section 3.05. Registration; Registration of Transfer and Exchange. The
Agent shall keep at the Corporate Trust Office a register (the register
maintained in such office being herein referred to as the "Security Register")
in which, subject to such reasonable regulations as it may prescribe, the Agent
shall provide for the registration of Security Certificates and of transfers of
Security Certificates (the Agent, in such capacity, the "Security Registrar").

     Upon surrender for registration of transfer of any Security Certificate at
the Corporate Trust Office, the Company shall execute and deliver to the Agent,
and the Agent shall authenticate, execute on behalf of the designated transferee
or transferees, and deliver, in the name of the designated transferee or
transferees, one or more new Security Certificates of any authorized
denominations and evidencing a like number of Securities.

     At the option of the Holder, Security Certificates may be exchanged for
other Security Certificates, of any authorized denominations and evidencing a
like number of Securities, upon surrender of the Security Certificates to be
exchanged at the Corporate Trust Office. Whenever any Security Certificates are
so surrendered for exchange, the Company shall execute and deliver to the Agent,
and the Agent shall authenticate, execute on behalf of the Holder, and deliver
the Security Certificates which the Holder making the exchange is entitled to
receive.

     All Security Certificates issued upon any registration of transfer or
exchange of a Security Certificate shall evidence the ownership of the same
number of Securities and be entitled to the same benefits and subject to the
same obligations, under this Agreement as the Securities evidenced by the
Security Certificate surrendered upon such registration of transfer or exchange.

     Every Security Certificate presented or surrendered for registration of
transfer or for exchange shall (if so required by the Agent) be duly endorsed,
or be accompanied by a written instrument of transfer in form satisfactory to
the Company and the Agent duly executed, by the Holder thereof or his attorney
duly authorized in writing.

     No service charge shall be made for any registration of transfer or
exchange of a Security Certificate, but the Company and the Agent may require
payment from the Holder of a sum sufficient to cover any tax or other
governmental charge that may be imposed in connection with any registration of
transfer or exchange of Security Certificates, other than any exchanges pursuant
to Sections 3.06 and 8.05 not involving any transfer. Notwithstanding the
foregoing, the Company shall not be obligated to execute and deliver to the
Agent, and the Agent shall not be obligated to authenticate, execute on behalf
of the Holder and deliver any Security Certificate presented or surrendered for
registration of transfer or for exchange on or after the Final Settlement Date
or the Termination Date. In lieu of delivery of a new Security Certificate, upon
satisfaction of the applicable conditions specified above in this Section and
receipt of appropriate registration or transfer instructions from such Holder,
the Agent shall (i) if the Final Settlement Date has occurred, deliver the
shares of Common Stock issuable in respect of the Purchase Contracts forming a
part of the Securities evidenced by such Security Certificate, or (ii) if a
Termination Event shall have occurred prior to the Final Settlement Date,
transfer the principal amount or liquidation amount, as the case may be, of the
Pledged Securities evidenced thereby, in each case subject to the applicable
conditions and in accordance with the applicable provisions of Article Five
hereof.

     The provisions of Clauses (1), (2), (3) and (4) below shall apply only to
Global Security Certificates:

         (1) Each Global Security Certificate authenticated and executed on
     behalf of the Holders under this Agreement shall be registered in the name
     of the Depositary designated for such Global Security Certificate or a
     nominee thereof and delivered to such Depositary or a nominee thereof or
     custodian therefor, an each such Global Security Certificate shall
     constitute a single Security Certificate for all purposes of this
     Agreement.

         (2) Notwithstanding any other provision in this Agreement, no Global
     Security Certificate may be exchanged in whole or in part of Security
     Certificates registered, and no transfer for a Global Security Certificate
     in whole or in part may be registered, in the name of any Person other than
     the Depositary for such Global Security Certificate or a nominee thereof
     unless (A) such Depositary (i) has notified the Company that it is
     unwilling or unable to

                                      -10-



     continue as Depositary for such Global Security Certificate or (ii) has
     ceased to be a clearing agency registered under the Exchange Act or (b)
     there shall have occurred and be continuing a default by the Company in
     respect to its obligations under one or more Purchase Contracts.

          (3) Subject to Clause (2) above, any exchange of a Global Security
     Certificate for other Security Certificates may be made in whole or in
     part, and all Security Certificates issued in exchange for a Global
     Security Certificate or any portion thereof shall be registered in such
     names as the Depositary for such Global Security Certificate shall direct.

          (4) Every Security Certificate authenticated and delivered upon
     registration of transfer of, or in exchange for or in lieu of, a Global
     Security Certificate or any portion thereof, whether pursuant to this
     Section, Section 3.04, 3.06, 5.09 or 8.05 or otherwise, shall be
     authenticated, executed on behalf of the Holders and delivered in the form
     of, and shall be, a Global Security Certificate, unless such Security
     Certificate is registered in the name of a Person other than the Depositary
     for such Global Security Certificate or a nominee thereof.

     Section 3.06. Mutilated, Destroyed, Lost and Stolen Security Certificates.
If any mutilated Security Certificate is surrendered to the Agent, the Company
shall execute and deliver to the Agent, and the Agent shall authenticate,
execute on behalf of the Holder, and deliver in exchange therefor, a new
Security Certificate, evidencing the same number of Securities and bearing a
number not contemporaneously outstanding.

     If there shall be delivered to the Company and the Agent (i) evidence to
their satisfaction of the destruction, loss or theft of any Security
Certificate, and (ii) such security or indemnity as may be required by them to
save each of them and any agent of any of them harmless, then, in the absence of
notice to the Company or the Agent that such Security Certificate has been
acquired by a bona fide purchaser, the Company shall execute and deliver to the
Agent, and the Agent shall authenticate, execute on behalf of the Holder, and
deliver to the Holder, in lieu of any such destroyed, lost or stolen Security
Certificate, a new Security Certificate, evidencing the same number of
Securities and bearing a number not contemporaneously outstanding.

     Notwithstanding the foregoing, the Company shall not be obligated to
execute and deliver to the Agent, and the Agent shall not be obligated to
authenticate, execute on behalf of the Holder, and deliver to the Holder, a
Security Certificate on or after the Final Settlement Date or the Termination
Date. In lieu of delivery of a new Security Certificate, upon satisfaction of
the applicable conditions specified above in this Section and receipt of
appropriate registration or transfer instructions from such Holder, the Agent
shall (i) if the Final Settlement Date has occurred, deliver the shares of
Common Stock issuable in respect of the Purchase Contracts forming a part of the
Securities evidenced by such Security Certificate, or (ii) if a Termination
Event shall have occurred prior to the Final Settlement Date, transfer the
principal amount of the Pledged Securities evidenced thereby, in each case
subject to the applicable conditions and in accordance with the applicable
provisions of Article Five hereof.

     Upon the issuance of any new Security Certificate under this Section, the
Company and the Agent may require the payment by the Holder 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 Agent)
connected therewith.

     Every new Security Certificate issued pursuant to this Section in lieu of
any destroyed, lost or stolen Security Certificate shall constitute an original
additional contractual obligation of the Company and of the Holder, whether or
not the destroyed, lost or stolen Security Certificate shall be at any time
enforceable by anyone, and shall be entitled to all the benefits and be subject
to all the obligations of this Agreement equally and proportionately with any
and all other Security Certificates delivered hereunder.

     The provisions of this Section are exclusive and shall preclude (to the
extent lawful) all other rights and remedies with respect to the replacement or
settlement of mutilated, destroyed, lost or stolen Security Certificates.

     Section 3.07. Persons Deemed Owners. Prior to due presentment of a Security
Certificate for registration of transfer, the Company and the Agent, and any
agent of the Company or the Agent, may treat the Person in whose name such
Security Certificate is registered as the owner of the Securities evidenced
thereby, for the purpose of receiving

                                      -11-



payments of distributions on the Pledged Securities, receiving payments of
Contract Fees, performance of the Purchase Contracts and for all other purposes
whatsoever, whether or not the payment of distributions on the Pledged
Securities or any Contract Fee payable in respect of the Purchase Contracts
constituting a part of the Securities evidenced thereby shall be overdue and
notwithstanding any notice to the contrary, and neither the Company nor the
Agent, nor any agent or the Company or the Agent, shall be affected by notice to
the contrary.

     Notwithstanding the foregoing, with respect to any Global Security
Certificate, nothing herein shall prevent the Company, the Agent or any agent of
the Company or the Agent, from giving effect to any written certification, proxy
or other authorization furnished by any Depositary (or its nominee), as a
Holder, with respect to such Global Security Certificate or impair, as between
such Depositary and owners of beneficial interests in such Global Security
Certificate, the operation of customary practices governing the exercise of
rights of such Depositary (or its nominee) as Holder of such Global Security
Certificate.

     Section 3.08. Cancellation. All Security Certificates surrendered for
delivery of shares of Common Stock on or after the Final Settlement Date,
transfer of Pledged Securities after the occurrence of a Termination Event or
pursuant to an Early Settlement or registration of transfer or exchange shall,
if surrendered to any Person other than the Agent, be delivered to the Agent
and, if not already cancelled, shall be promptly cancelled by it. The Company
may at any time deliver to the Agent for cancellation any Security Certificates
previously authenticated, executed and delivered hereunder which the Company may
have acquired in any manner whatsoever, and all Security Certificates so
delivered shall, upon Issuer Order, be promptly cancelled by the Agent. No
Security Certificates shall be authenticated, executed on behalf of the Holder
and delivered in lieu of or in exchange for any Security Certificates cancelled
as provided in this Section, except as expressly permitted by this Agreement.
All cancelled Security Certificates held by the Agent shall be disposed of as
directed by Issuer Order.

     If the Company or any Affiliate of the Company shall acquire any Security
Certificate, such acquisition shall not operate as a cancellation of such
Security Certificate unless and until such Security Certificate is delivered to
the Agent cancelled or for cancellation.

     Section 3.09. Securities Not Separable. Notwithstanding anything contained
herein or in the Security Certificates to the contrary, for so long as the
Purchase Contract underlying a Security remains in effect such Security shall
not be separable into its constituent parts, and the rights and obligations of
the Holder of such Security in respect of the Pledged Securities and Purchase
Contracts constituting such Security may be acquired, and may be transferred and
exchanged, only as a Security. Other than a Security Certificate evidencing a
Security, no Holder of a Security, or any transferee thereof, shall be entitled
to receive a certificate evidencing the ownership of Pledged Securities or the
rights and obligations of the Holder and the Company under a Purchase Contract
for so long as the Purchase Contract underlying the Security remains in effect.

                                  ARTICLE FOUR
                             THE PLEDGED SECURITIES

     Section 4.01. Payment of Distributions; Rights to Distributions Preserved.
Distributions on any Pledged Security which is paid on any Payment Date shall,
subject to receipt thereof by the Agent from the Collateral Agent as provided by
the terms of the Pledge Agreement, be paid to the Person in whose name the
Security Certificate (or one or more Predecessor Security Certificates) of which
such Pledged Security is a part is registered at the close of business on the
Record Date next preceding such Payment Date.

     Each Security Certificate evidencing Pledged Securities delivered under
this Agreement upon registration of transfer of or in exchange for or in lieu of
any other Security Certificate shall carry the rights to distributions accrued
and unpaid, and to accrue, which were carried by the Pledged Securities
underlying such other Security Certificate.

     In the case of any Security with respect to which Early Settlement of the
underlying Purchase Contract is effected on an Early Settlement Date after any
Record Date and on or prior to the next succeeding Payment Date, distributions
on the Pledged Securities underlying such Security otherwise payable on such
Payment Date shall be payable on such

                                      -12-



Payment Date notwithstanding such Early Settlement, and such distributions
shall, subject to receipt thereof by the Agent, be paid to the Person in whose
name the Security Certificate (or one or more Predecessor Security Certificates)
is registered at the close of business on the Record Date. Except as otherwise
expressly provided in the immediately preceding sentence, in the case of any
Security with respect to which Early Settlement of the underlying Purchase
Contract is effected on an Early Settlement Date, distributions on the related
Pledged Securities that would otherwise be payable after the Early Settlement
Date shall not be payable hereunder to the Holder of such Security.

     Section 4.02. Transfer of Pledged Securities Upon Occurrence of Termination
Event. Upon the occurrence of a Termination Event and the transfer to the Agent
of the Pledged Securities underlying such Securities pursuant to the terms of
the Pledge Agreement, the Agent shall request transfer instructions with respect
to such Pledged Securities from each Holder of Securities by written request
mailed to such Holder at his address as it appears in the Security Register, in
respect of the Pledged Securities underlying the Security Certificate held by
such Holder. Upon surrender to the Agent of a Security Certificate with such
transfer instructions in proper form for transfer of the Pledged Securities by
Federal Reserve BankWire, book entry transfer through the facilities of the
Depositary Trust Company, or other appropriate procedure, the Agent shall
transfer the Pledged Securities evidenced by such Security Certificate to such
Holder in accordance with such instructions. If a Security Certificate is not
duly surrendered to the Agent with appropriate transfer instructions, the Agent
shall hold the Pledged Securities evidenced by such Security Certificate as
custodian for the Holder of such Security Certificate.

     Pledged Securities shall be transferred only in denominations of
$__________ and integral multiples thereof. As promptly as practicable following
the occurrence of a Termination Event, the Agent shall determine the excess of
(i) the aggregate principal amount or liquidation preference, as the case may
be, of Pledged Securities underlying the Outstanding Securities over (ii) the
aggregate principal amount or liquidation preference, as the case may be, of
Pledged Securities in denominations of $__________ and integral multiples
thereof transferrable to Holders of record on the date of such Termination Event
(such excess being herein referred to as the "Excess Pledged Securities"). As
soon as practicable after transfer to the Agent of the Pledged Securities
underlying the Outstanding Securities as provided in the Pledge Agreement, the
Agent shall sell the Excess Pledged Securities to or through one or more
registered broker dealers at then prevailing prices. The Agent shall deduct from
the proceeds of such sales all commissions and other out-of-pocket transaction
costs incurred in connection with such sales of Excess Pledged Securities and,
until the net proceeds of such sale or sales have been distributed to Holders of
the Securities, the Agent shall hold such proceeds in trust for the Holders of
Securities. Each Holder shall be entitled to receive a portion, if any, of such
net proceeds in lieu of Pledged Securities with a principal amount of less than
$____ determined by multiplying the aggregate amount of such net proceeds by a
fraction, the numerator of which is the fraction of $_____________ in principal
amount of Pledged Securities to which such Holder would otherwise be entitled
(after taking into account all Securities then held by such Holder) and the
denominator of which is the aggregate principal amount of Excess Pledged
Securities.

                                  ARTICLE FIVE
                             THE PURCHASE CONTRACTS

     Section 5.01. Purchase of Shares of Common Stock. Each Purchase Contract
shall obligate the Holder of the related Security to purchase, and the Company
to sell, on the Final Settlement Date at a price equal to the Stated Amount, a
number of shares of Common Stock equal to the Settlement Rate, unless, on or
prior to the Final Settlement Date, there shall have occurred a Termination
Event or an Early Settlement with respect to the Security of which such Purchase
Contract is a part. The "Settlement Rate" is equal to (a) if the Applicable
Market Value (as defined below) is greater than $____ (the "Threshold
Appreciation Price"), __________ of a share of Common Stock per Purchase
Contract, (b) if the Applicable Market Value is less than or equal to the
Threshold Appreciation Price but is greater than the Stated Amount, a fractional
share of Common Stock per Purchase Contract equal to the Stated Amount divided
by the Applicable Market Value (rounded upward or downward to the nearest
1/10,000th of a share) and (c) if the Applicable Market Value is less than or
equal to the Stated Amount, one share of Common Stock per Purchase Contract, in
each case subject to adjustment as provided in Section 5.06. As provided in
Section 5.10, no fractional shares of Common Stock will be issued upon
settlement of Purchase Contracts.

     The "Applicable Market Value" means the average of the Closing Prices per
share of Common Stock on each of the twenty consecutive Trading Days ending on
the last Trading Day immediately preceding the Final Settlement Date.

                                      -13-



The "Closing Price" of the Common Stock on any date of determination means the
closing sale price (or, if no closing price is reported, the last reported sale
price) of the Common Stock on the New York Stock Exchange (the "NYSE") on such
date or, if the Common Stock 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 the Common Stock is so listed, or if the Common
Stock is not so listed on a United States national or regional securities
exchange, as reported by The Nasdaq Stock Market, or, if the Common Stock is not
so reported, the last quoted bid price for the Common Stock in the over-
the-counter market as reported by the National Quotation Bureau or similar
organization, or, if such bid price is not available, the market value of the
Common Stock on such date as determined by a nationally recognized independent
investment banking firm retained for this purpose by the Company. A "Trading
Day" means a day on which the Common Stock (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 the Common Stock.

     Each Holder of a Security Certificate evidencing Securities, by his
acceptance thereof, irrevocably authorizes the Agent to enter into and perform
the related Purchase Contracts on his behalf as his attorney-in-fact, agrees to
be bound by the terms and provisions thereof, covenants and agrees to perform
his obligations under such Purchase Contracts, consents to the provisions
hereof, irrevocably authorizes the Agent as his attorney-in-fact to enter into
and perform the Pledge Agreement on his behalf as his attorney-in-fact, and
consents to and agrees to be bound by the Pledge of the Pledged Securities
underlying such Security Certificate pursuant to the Pledge Agreement. Each
Holder of a Security, by his acceptance thereof, further irrevocably covenants
and agrees that, to the extent and in the manner provided in Section 5.04 and
the Pledge Agreement, but subject to the terms thereof, payments in respect of
principal or redemption price of the Pledged Securities on the Final Settlement
Date shall be paid by the Collateral Agent to the Company in satisfaction of
such Holder's obligations under such Purchase Contract and such Holder shall
acquire no right, title or interest in such payments.

     Upon registration of transfer of a Security Certificate evidencing Purchase
Contracts, the transferee shall be bound (without the necessity of any other
action on the part of such transferee), under the terms of this Agreement, the
Purchase Contracts evidenced thereby and the Pledge Agreement and the transferor
shall be released from the obligations under the Purchase Contracts evidenced by
the Security Certificates so transferred. The Company covenants and agrees, and
each Holder of a Security Certificate, by his acceptance thereof, likewise
covenants and agrees, to be bound by the provisions of this paragraph.

     Section 5.02. Contract Fees. Subject to Section 5.03, the Company shall
pay, on each Payment Date, the Contract Fees payable in respect of each Purchase
Contract to the Person in whose name the Security Certificate (or one or more
Predecessor Security Certificates) evidencing such Purchase Contract is
registered at the close of business on the Record Date next preceding such
Payment Date. The Contract Fee will be payable at the office of the Agent in the
City of __________ maintained for that purpose or, at the option of the Company,
by check mailed to the address of the Person entitled thereto at such address as
it appears on the Security Register.

     Each Security Certificate delivered under this Agreement upon registration
of transfer of or in exchange for or in lieu of any other Security Certificate
shall carry the rights to Contract Fees accrued and unpaid, and to accrue, which
were carried by the Purchase Contracts evidenced by such other Security
Certificate.

     In the case of any Security with respect to which Early Settlement of the
underlying Purchase Contract is effected on an Early Settlement Date after any
Record Date and on or prior to the next succeeding Payment Date, Contract Fees
otherwise payable on such Payment Date shall be payable on such Payment Date
notwithstanding such Early Settlement, and such Contract Fees shall be paid to
the Person in whose name the Security Certificate evidencing such Security (or
one or more Predecessor Security Certificates) is registered at the close of
business on such Record Date. Except as otherwise expressly provided in the
immediately preceding sentence, in the case of any Security with respect to
which Early Settlement of the underlying Purchase Contract is effected on an
Early Settlement Date, Contract Fees that would otherwise be payable after the
Early Settlement Date with respect to the Purchase Contract underlying such
Security shall not be payable.

                                      -14-



     Section 5.03. Deferral of Payment Dates for Contract Fee. The Company shall
have the right, at any time prior to the Final Settlement Date, to defer the
payment of any or all of the Contract Fees otherwise payable on any Payment
Date, but only if the Company shall give the Holders and the Agent written
notice of its election to defer such payment (specifying the amount to be
deferred) at least ten Business Days prior to the earlier of (i) the next
succeeding Payment Date or (ii) the date the Company is required to give notice
of the Record Date or Payment Date with respect to payment of such Contract Fee
to the New York Stock Exchange or other applicable self-regulatory organization
or to Holders of the Securities, but in any event not less than two Business
Days prior to such Record Date. Any Contract Fees so deferred shall bear
additional Contract Fees thereon at the rate of per annum set forth in Appendix
_______ hereto (computed on the basis set forth in Appendix ____), compounding
on each succeeding Payment Date, until paid in full. Deferred Contract Fees (and
additional Contract Fees accrued thereon) shall be due on the next succeeding
Payment Date except to the extent that payment is deferred pursuant to this
Section. No Contract Fees may be deferred to a date that is after the Final
Settlement Date or, with respect to any particular Purchase Contract, Early
Settlement thereof.

     Section 5.04. Payment of Purchase Price. The purchase price for the shares
of Common Stock purchased pursuant to a Purchase Contract shall be paid by
application of payments received by the Company on the Final Settlement Date
from the Collateral Agent pursuant to the Pledge Agreement in respect of the
principal or redemption price, as the case may be, of the Pledged Securities
Pledged to secure the obligations of the relevant Holder under such Purchase
Contract. Such application shall satisfy in full the obligations under such
Purchase Contract of the Holder of the Security of which such Purchase Contract
is a part.

     The Company shall not be obligated to issue any shares of Common Stock in
respect of a Purchase Contract or deliver any certificates therefor to the
Holder unless it shall have received payment in full of the aggregate purchase
price for the shares of Common Stock to be purchased thereunder in the manner
herein set forth.

     Section 5.05. Issuance of Share of Common Stock. Unless a Termination Event
shall have occurred on or prior to the Final Settlement Date, on the Final
Settlement Date, upon its receipt of payment in full of the purchase price for
the shares of Common Stock purchased by the Holders pursuant to the foregoing
provisions of this Article, and subject to Section 5.06(b), the Company shall
deposit with the Agent, for the benefit of the Holders of the Outstanding
Securities, one or more certificates representing the shares of Common Stock
registered in the name of the Agent (or its nominee) as custodian for the
Holders (such certificates for shares of Common Stock, together with any
dividends or distributions with respect thereto, being hereinafter referred to
as the "Final Settlement Fund") to which the Holders are entitled hereunder.
Subject to the foregoing, upon surrender of a Security Certificate to the Agent
on or after the Final Settlement Date, together with settlement instructions
thereon duly completed and executed, the Holder of such Security Certificate
shall be entitled to receive in exchange therefor a certificate representing
that number of whole shares of Common Stock with such Holder is entitled to
receive pursuant to the provisions of this Article Five (after taking into
account all Securities then held by such Holder) together with cash in lieu of
fractional shares as provided in Section 5.10 and any dividends or distributions
with respect to such shares constituting part of the Final Settlement Fund, but
without any interest thereon, and the Security Certificate so surrendered shall
forthwith be cancelled. Such shares shall be registered in the name of the
Holder or the Holder's designee as specified in the settlement instructions on
the Security Certificate.

     If any shares of Common Stock issued in respect of a Purchase Contract are
to be registered to a Person other than the Person in whose name the Security
Certificate evidencing such Purchase Contract is registered, no such
registration shall be made unless the Person requesting such registration has
paid any transfer and other taxes required by reason of such registration in a
name other than that of the registered Holder of the Security Certificate
evidencing such Purchase Contractor has established to the satisfaction of the
Company that such tax either has been paid or is not payable.

     Section 5.06. Adjustment of Settlement Rate. (a) Adjustments for Dividends,
Distributions, Stock Splits, Etc. (1) In case the Company shall pay or make a
dividend or other distribution on any class of Common Stock of the Company in
Common Stock, the Settlement Rate in effect at the opening of business on the
day following the date fixed for the determination of stockholders entitled to
receive such dividend or other distribution shall be increased by dividing such
Settlement Rate by a fraction of which the numerator shall be the number of
shares of Common Stock outstanding at the close of business on the date fixed
for such determination and the denominator shall be the sum of such number of

                                      -15-



shares and the total number of shares constituting such dividend or other
distribution, such increase to become effective immediately after the opening of
business on the day following the date fixed for such determination. For the
purposes of this paragraph (1), the number of shares of Common Stock at any time
outstanding shall not include shares held in the treasury of the Company but
shall include shares issuable in respect of scrip certificates issued in lieu of
fractions of shares of Common Stock. The Company will not pay any dividend or
make any distribution on shares of Common Stock held in the treasury of the
Company.

         (2) In case the Company shall issue rights, options or warrants to all
holders of its Common Stock (not being available on an equivalent basis to
Holders of the Securities upon settlement of the Purchase Contracts underlying
such Securities) entitling them, for a period expiring within 45 days after the
record date for the determination of stockholders entitled to receive such
rights, options or warrants, to subscribe for or purchase shares of Common Stock
at a price per share less than the Current Market Price per share of the Common
Stock on the date fixed for the determination of stockholders entitled to
receive such rights, options or warrants (other than pursuant to a dividend
reinvestment plan), the Settlement Rate in effect at the opening of business on
the day following the date fixed for such determination shall be increased by
dividing such Settlement Rate by a fraction of which the numerator shall be the
number of shares of Common Stock outstanding at the close of business on the
date fixed for such determination plus the number of shares of Common Stock
which the aggregate of the offering price of the total number of shares of
Common Stock so offered for subscription or purchase would purchase at such
Current Market Price and the denominator shall be the number of shares of Common
Stock outstanding at the close of business on the date fixed for such
determination plus the number of shares of Common Stock so offered for
subscription or purchase, such increase to become effective immediately after
the opening of business on the day following the date fixed for such
determination. For the purposes of this paragraph (2), the number of shares of
Common Stock at any time outstanding shall not include shares held in the
treasury of the Company but shall include shares issuable in respect of scrip
certificates issued in lieu of fractions of shares of Common Stock. The Company
shall not issue any such rights, options or warrants in respect of shares of
Common Stock held in the treasury of the Company.

         (3) In case outstanding shares of Common Stock shall be subdivided into
a greater number of shares of Common Stock, the Settlement Rate in effect at the
opening of business on the day following the day upon which such subdivision
becomes effective shall be proportionately increased, and, conversely, in case
outstanding shares of Common Stock shall each be combined into a smaller number
of shares of Common Stock, the Settlement Rate in effect at the opening of
business on the day following the day upon which such combination becomes
effective shall be proportionately reduced, such increase or reduction, as the
case may be, to become effective immediately after the opening of business on
the day following the day upon which such subdivision or combination becomes
effective.

         (4) In case the Company shall, by dividend or otherwise, distribute to
all holders of its Common Stock evidences of its indebtedness or assets
(including securities, but excluding any rights or warrants referred to in
paragraph (2) of this Section, any dividend or distribution paid exclusively in
cash and any dividend or distribution refereed to in paragraph (1) of this
Section), the Settlement Rate shall be adjusted so that the same shall equal the
rate determined by dividing the Settlement Rate in effect immediately prior to
the close of business on the date fixed for the determination of stockholders
entitled to receive such distribution by a fraction of which the numerator shall
be the Current Market Price per share of the Common Stock on the date fixed for
such determination less the then fair market value (as determined by the Board
of Directors, whose determination shall be conclusive and described in a Board
Resolution filed with the Agent) of the portion of the assets or evidences of
indebtedness so distributed applicable to one share of Common Stock and the
denominator shall all be such Current market Price per share of the Common
Stock, such adjustment to become effective immediately prior to the opening of
business on the day following the date fixed for the determination of
stockholders entitled to receive such distribution. In any case in which this
paragraph (4) is applicable, paragraph (2) of this Section shall not be
applicable.

         (5) In case the Company shall, by dividend or otherwise, distribute to
all holders of its Common Stock cash (excluding any cash that is distributed in
a Reorganization Event to which Section 5.06(b) applies or as part of a
distribution referred to in paragraph (4) of this Section) in an aggregate
amount that, combined together with (I) the aggregate amount of any other
distributions to all holders of its Common Stock made exclusively in cash within
the 12 months preceding the date of payment of such distribution and in respect
of which no adjustment pursuant to this paragraph (5) or paragraph (6) of this
Section has been made and (II) the aggregate of any cash plus the fair market
value

                                      -16-



(as determined by the Board of Directors, whose determination shall be
conclusive and described in a Board Resolution) of consideration payable in
respect of any tender or exchange offer by the Company or any of its
subsidiaries of all or any portion of the Common Stock concluded within the 12
months preceding the date of payment of such distribution and in respect of
which no adjustment pursuant to this paragraph (5) or paragraph (6) of this
Section has been made, exceeds 10% of the product of the Current Market Price
per share of the Common Stock on the date for the determination of holders of
shares of Common Stock entitled to receive such distribution times the number of
shares of Common Stock outstanding on such date, then, and in each such case,
immediately after the close of business on such date for determination, the
Settlement Rate shall be increased so that the same shall equal the rate
determined by dividing the Settlement Rate in effect immediately prior to the
close of business on the date fixed for determination of the stockholders
entitled to receive such distribution by a fraction (i) the numerator of which
shall be equal to the Current Market Price per share of the Common Stock on the
date fixed for such determination less an amount equal to the quotient of (x)
the excess of such combined amount over such 10% and (y) the number of shares of
Common Stock outstanding on such date for determination and (ii) the denominator
of which shall be equal to the Current Market Price per share of the Common
Stock on such date for determination.

         (6) In case a tender or exchange offer made by the Company or any
subsidiary of the Company for all or any portion of the Common Stock shall
expire and such tender or exchange offer (as amended upon the expiration
thereof) shall require the payment to stockholders (based on the acceptance (up
to any maximum specified in the terms of the tender or exchange offer) of
Purchased Shares) of an aggregate consideration having a fair market value (as
determined by the Board of Directors, whose determination shall be conclusive
and described in a Board Resolution) that combined together with (I) the
aggregate of the cash plus the fair market value (as determined by the Board of
Directors, whose determination shall be conclusive and described in a Board
Resolution), as of the expiration of such tender or exchange offer, of
consideration payable in respect of any other tender or exchange offer, by the
Company or any subsidiary of the Company for all or any portion of the Common
Stock expiring within the 12 months preceding the expiration of such tender or
exchange offer and in respect of which no adjustment pursuant to paragraph (5)
of this Section or this paragraph (6) has been made and (II) the aggregate
amount of any distributions to all holders of the Company's Common Stock made
exclusively in cash within 12 months preceding the expiration of such tender or
exchange offer and in respect of which no adjustment pursuant to paragraph (5)
of this Section or this paragraph (6) has been made, exceeds 10% of the product
of the Current Market Price per share of the Common Stock as of the last time
(the "Expiration Time") tenders could have been made pursuant to such tender or
exchange offer (as it may be amended) times the number of shares of Common Stock
outstanding (including any tendered shares) on the Expiration Time, then, and in
each such case, immediately prior to the opening of business on the day after
the date of the Expiration Time, the Settlement Rate shall be adjusted so that
the same shall equal the rate determined by dividing the Settlement Rate
immediately prior to close of business on the date of the Expiration Time by a
fraction (i) the numerator of which shall be equal to (A) the product of (I) the
Current Market Price per share of the Common Stock on the date of the Expiration
Time and (II) the number of shares of Common Stock outstanding (including any
tendered shares) on the Expiration Time less (B) the amount of cash plus the
fair market value (determined as aforesaid) of the aggregate consideration
payable to stockholders based on the acceptance (up to any maximum specified in
the terms of the tender or exchange offer) of Purchased shares, and (ii) the
denominator of which shall be equal to the product of (A) the Current Market
Price per share of the Common Stock as of the Expiration Time and (B) the number
of shares of Common Stock outstanding (including any tendered shares) as of the
Expiration Time less the number of all shares validly tendered and not withdrawn
as of the Expiration Time (the shares deemed so accepted, up to any such maximum
being referred to as the "Purchased Shares").

         (7) The reclassification of Common Stock into securities including
securities other than Common Stock (other than any reclassification upon a
Reorganization Event to which Section 5.06(b) applies) shall be deemed to
involve (a) a distribution of such securities other than Common Stock to all
holders of Common Stock (and the effective date of such reclassification shall
be deemed to be "the date fixed for the determination of stockholders entitled
to receive such distribution" and the "date fixed for such determination" within
the meaning of paragraph (4) of this Section), and (b) a subdivision or
combination, as the case may be, of the number of share of Common Stock
outstanding immediately prior to such reclassification into the number of shares
of Common Stock outstanding immediately thereafter (and the effective date of
such reclassification shall be deemed to be "the day upon which such subdivision
becomes effective" or "the day upon which such combination becomes effective",
as the case may be, and "the day upon which such subdivision or combination
becomes effective" within the meaning of paragraph (3) of this Section).

                                      -17-



         (8)  The "Current Market Price" per share of Common Stock on any day
means the average of the daily Closing Prices for the 5 consecutive Trading Days
selected by the Company commencing not more than 20 Trading Days before, and
ending not later than, the earlier of the day in question and the day before the
"ex" date with respect to the issuance or distribution requiring such
computation. For purposes of this paragraph, the term "`ex' date", when used
with respect to any issuance or distribution, shall mean the first date on which
the Common Stock trades regular way on such exchange or in such market without
the right to receive such issuance or distribution.

         (9)  All adjustments to the Settlement Rate shall 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 lower 1/10,000th of a share). No adjustment in
the Settlement 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 subparagraph are not required to be made
shall be carried forward and taken into account in any subsequent adjustment. If
an adjustment is made to the Settlement Rate pursuant to paragraph (1), (2),
(3), (4), (5), (6), (7) or (10) of this Section 5.06(a), an adjustment shall
also be made to the Applicable Market Value solely to determine which of clauses
(a), (b) or (c) of the definition of Settlement Rate in Section 5.01 will apply
on the Final Settlement Date. Such adjustment shall be made by multiplying the
Applicable Market Value by a fraction of which the numerator shall be the
Settlement Rate in clause (c) of the Settlement Rate definition in Section 5.01
immediately after such adjustment pursuant to paragraph (1),(2), (3), (4), (5),
(6), (7) or (10) of this Section 5.06(a) and the denominator shall be the
Settlement Rate in clause (c) of the Settlement Rate definition in Section 5.01
immediately before such adjustment.

         (10) The Company may make such increases in the Settlement Rate, in
addition to those required by this Section, as it considers to be advisable in
order to avoid or diminish any income tax to any holders of shares of common
Stock resulting from any dividend or distribution of stock or issuance of rights
or warrants to purchase or subscribe for stock or from any event treated as such
for income tax purposes or for any other reasons.

     (b) Adjustment for Consolidation, Merger or Other Reorganization Event. In
the event of (i) any consolidation or merger of the Company, with or into
another Person (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), (ii) any sale, transfer,
lease or conveyance to another Person of the property of the Company as an
entirety or substantially as an entirety, (iii) any statutory exchange of
securities of the Company with another person (other than in connection with a
merger or acquisition) or (iv) any liquidation, dissolution or winding up of the
Company (any such event, a "Reorganization Event"), the Settlement Rate will be
adjusted to provide that each Holder of Securities will receive on the Final
Settlement Date with respect to each Purchase Contract forming a part thereof,
the kind and amount of securities, cash and other property receivable upon such
Reorganization Event by a Holder of the number of shares of Common Stock
issuable on account of each Purchase Contract if the Final Settlement Date had
occurred immediately prior to such Reorganization Event, assuming such Holder of
Common Stock is not a Person with which the Company consolidated or into which
the Company merged or which merged into the Company or to which such sale or
transfer was made, as the case may be ("constituent Person"), or an Affiliate of
a constituent Person, and failed to exercise his rights of election, if any, as
to the kind or amount of securities, cash and other property receivable upon
such Reorganization Event (provided that if the kind or amount of securities,
cash and other property receivable upon such Reorganization Event is not the
same for each share of Common Stock held immediately prior to such
Reorganization event by other than a constituent Person or an Affiliate thereof
and in respect of which such rights of election shall not have been exercised
("nonelecting share"), then for the purpose of this Section the kind and amount
of securities, cash and other property receivable upon such Reorganization Event
by each nonelecting share shall be deemed to be the kind and amount so
receivable per share by a plurality of the nonelecting shares). In the event of
such a Reorganization Event, the Person formed by such consolidation, merger or
exchange or the Person which acquires the assets of the Company or, in the event
of a liquidation or dissolution of the Company, the Company or a liquidating
trust created in connection therewith, shall execute and deliver to the Agent an
agreement supplemental hereto providing that the Holders of each Outstanding
Security shall have the rights provided by this Section 5.06. Such supplemental
agreement shall provide for adjustments which, for events subsequent to the
effective date of such supplemental agreement, shall be as nearly equivalent as
may be practicable to the adjustments provided for in this Section. The above
provisions of this Section shall similarly apply to successive Reorganization
Events.

                                      -18-



     Section 5.07.  Notice of Adjustments and Certain Other Events. (a) Whenever
the settlement Rate is adjusted as herein provided, the Company shall:

         (i)  forthwith compute the adjusted Settlement Rate in accordance with
     Section 5.06 and prepare and transmit to the Agent an Officer's Certificate
     setting forth the Settlement Rate, the method of calculation thereof in
     reasonable detail, and the acts requiring such adjustment and upon which
     such adjustment is based; and

         (ii) within 10 Business Days following the occurrence of an event that
     permits or requires an adjustment to the Settlement Rate pursuant to
     Section 5.06 (or if the Company is not aware of such occurrence, as soon as
     practicable after becoming so aware), provide a written notice to the
     Holders of the Securities of the occurrence of such event and a statement
     in reasonable detail setting forth the method by which the adjustment to
     the Settlement Rate was determined and setting forth the adjusted
     Settlement Rate.

     (b) The Agent shall not at any time be under any duty or responsibility to
any holder of Securities to determine whether any facts exist which may require
any adjustment of the Settlement Rate, or with respect to the nature or extent
or calculation of any such adjustment when made, or with respect to the method
employed in making the same. The Agent shall not be accountable with respect to
the validity or value (or the kind or amount) of any shares of Common Stock, or
of any securities or property, which may at the time be issued or delivered with
respect to any Purchase Contract; and the Agent makes no representation with
respect thereto. The Agent shall not be responsible for any failure of the
Company to issue, transfer or deliver any shares of Common Stock pursuant to a
Purchase Contract or to comply with any of the duties, responsibilities or
covenants of the Company contained in this Article.

     Section 5.08. Termination Event; Notice. The Purchase Contracts and the
obligations and rights of the Company and the Holders thereunder, including,
without limitation, the rights of the Holders to receive and the obligation of
the Company to pay any Contract Fee, shall immediately and automatically
terminate, without the necessity of any notice or action by any Holder, the
Agent or the Company, if, on or prior to the Final Settlement Date, a
Termination Event shall have occurred. Upon the occurrence of a Termination
Event, the Company shall give written notice to the Agent, the Collateral Agent
and to the Holders, at their addresses as they appear in the Security Register.
Upon and after the occurrence of a Termination Event, the Securities shall
thereafter represent the right to receive the Pledged Securities forming a part
of such Securities in accordance with the provisions of Section 4.02 and the
Pledge Agreement.

     Section 5.09. Early Settlement. (a) Subject to and upon compliance with the
provisions of this Section 5.09 at the option of the Holder thereof, any
Purchase Contracts underlying securities having an aggregate Stated Amount to
$____________ or an integral multiple thereof may be settled early ("Early
Settlement") as provided herein. In order to exercise the right to effect Early
Settlement with respect to any Purchase Contracts, the Holder of the Security
Certificate evidencing such Purchase Contracts shall deliver such Security
Certificate to the Agent at the Corporate Trust Office duly endorsed for
transfer to the Company or in blank with the form of Election to Settle Early on
the reverse thereof duly completed and accompanied by payment in the form of a
certified or cashier's check payable to the order of the Company in immediately
available funds in an amount (the "Early Settlement Amount") equal to [(i) the
product of (A) the Stated Amount times (B) the number of Purchase Contracts with
respect to which the Holder has elected to effect Early Settlement minus (ii)
the aggregate amount of Contract Fees, if any, otherwise payable on or prior to
the immediately preceding Payment Date deferred at the option of the Company
pursuant to Section 5.03 and remaining unpaid as of such immediately preceding
Payment Date plus (iii) if such delivery is made with respect to any Purchase
Contracts during the period from the close of business on any Record Date next
preceding any Payment Date to the opening of business on such Payment Date, an
amount equal to the sum of (x) the Contract Fees payable on such Payment Date
with respect to such Purchase Contracts plus (y) the distributions on the
related Pledged Securities payable on such Payment Date]. Except as provided in
the immediately preceding sentence and subject to the last paragraph of Section
5.02, no payment or adjustment shall be made upon Early Settlement of any
Purchase Contract on account of any Contract Fees accrued on such Purchase
Contract or on account of any dividends on the Common Stock issued upon such
Early Settlement. If the foregoing requirements are first satisfied with respect
to Purchase Contracts underlying any Securities at or prior to 5:00 p.m., New
York City time, on a Business Day, such day shall be the "Early Settlement Date"
with respect to such Securities and if such requirements are first satisfied
after 5:00 p.m., New York City time, on a Business Day or on a day that is not a

fractional interest in an amount equal to the value of such fractional shares at
the Closing Price per share on the Trading Day immediately preceding the Final

evidencing a Purchase Contract or any issuance of a share of Common Stock in a
name other than that of the registered Holder of a Security Certificate
surrendered in respect of the Purchase Contracts evidenced thereby, other than
in the name of the Agent, as custodian for such Holder, and the Company shall
not be required to issue or deliver such share certificates or Security
Certificates unless or until the Person or Persons requesting the transfer or
issuance thereof shall have paid to the Company the amount of such tax or shall

its assets to any Person, except that the Company may merge or consolidate with,
or sell or convey all or substantially all of its assets to, any other Person,
provided that (i) the Company shall be the continuing corporation, or the
successor (if other than the Company) shall be a corporation organized and
existing under the laws of the United States of America or a State thereof and
such corporation shall assume the obligations of the Company under the Purchase
Contracts, this Agreement and the Pledge Agreement by one or more supplemental
agreements in form satisfactory to the Agent and the Collateral Agent, executed
and delivered to the Agent and the Collateral Agent by such corporation, and
(ii) the Company or such successor corporation, as the case may be, shall not,
immediately after such merger or consolidation, or such sale or conveyance, be

such consolidation, merger, sale or conveyance and upon any such assumption by
the successor corporation, such successor corporation shall succeed to and be
substituted for the Company with the same effect as if it had been named herein
as the Company. Such successor corporation thereupon may cause to be signed, and
may issue either in its own name or in the name of Radio One, Inc., any or all
of the Security Certificates evidencing Securities issuable hereunder which
theretofore shall not have been signed by the Company and delivered to the
Agent; and, upon the order of such successor corporation, instead of the
Company, and subject to all the terms, conditions and limitations in this
Agreement prescribed, the Agent shall authenticate and execute on behalf of the
Holders and deliver any Security Certificates which previously shall have been
signed and delivered by the officers of the Company to the Agent for
authentication and execution, and any Security Certificate evidencing Securities
which such successor corporation thereafter shall cause to be signed and
delivered to the Agent for that purpose. All the Security Certificates so issued
shall in all respects have the same legal rank and benefit under this Agreement
as the Security Certificates theretofore or thereafter issued in accordance with
the terms of this Agreement as though all of such Security Certificates had been
issued at the date of the execution hereof.

     In case of any such consolidation, merger, sale or conveyance such change
in phraseology and form (but not in substance) may be made in the Security
Certificates evidencing Securities thereafter to be issued as may be
appropriate.

     Section 9.03. Opinion of Counsel to Agent. The Agent, subject to Sections
7.01 and 7.03, may receive an Opinion of Counsel as conclusive evidence that any
such consolidation, merger, sale or conveyance, and any such assumption,
complies with the provisions of this Article.

any change in the location of any such other office or agency. The Company
hereby designates as the place of payment for the Securities the Corporate Trust

                     Form of Reverse of Security Certificate

     Each Purchase Contract evidenced hereby is governed by a Purchase Contract
Agreement, dated as of ____________ (the "Purchase Contract Agreement"), between
the Company and __________, as Agent (herein called the "Agent"), to which
Purchase Contract Agreement and supplemental agreements thereto reference is
hereby made for a description of the respective rights, limitations of rights,
obligations, duties and immunities thereunder of the Agent, the Company, and the
Holders and of the terms upon which the Security Certificates are, and are to
be, executed and delivered.

     Each Purchase Contract evidenced hereby obligates the Holder of this
Security Certificate to purchase, and the Company to sell, on the Final
Settlement Date at a price equal to the Stated Amount, a number of shares of
Common Stock of the Company equal to the Settlement Rate, unless, on or prior to
the Final Settlement Date, there shall have occurred a Termination Event or an
Early Settlement with respect to the Security of which such Purchase Contract is
a part. The "Settlement Rate" is equal to (a) if the Applicable Market Value (as
defined below) is greater than $_________ (the "Threshold Appreciation Price"),
of a share of Common Stock per Purchase Contract, (b) if the Applicable Market
Value is less than or equal to the Threshold Appreciation Price but is greater
than the Stated Amount, a fractional share of Common Stock per Purchase Contract
equal to the Stated Amount divided by the Applicable Market Value and (c) if the
Applicable Market Amount is less than or equal to the Stated Amount, one share
of Common Stock per Purchase Contract, in each case subject to adjustment as
provided in the Purchase Contract. No fractional shares of Common Stock will be
issued upon settlement of Purchase Contracts, as provided in the Purchase
Contract Agreement.

     The "Applicable Market Value" means the average of the Closing Prices per
share of Common Stock on each of the twenty consecutive Trading Days ending on
the last Trading Day immediately preceding the Final Settlement Date. The
"Closing Price" of the Common Stock on any date of determination means the
closing sale price (or, if no closing price is reported, the last reported sale
price) of the Common Stock on the New York Stock Exchange (the "NYSE") on such
date or, if the Common Stock 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 the Common Stock is so listed, or if the Common
Stock is not so listed on a United States national or regional securities
exchange, as reported by The Nasdaq Stock Market, or, if the Common Stock is not
so reported, the last quoted bid price for the Common Stock in the over-
the-counter market as reported by the National Quotation Bureau or similar
organization, or, if such bid price is not available, the market value of the
Common Stock on such date as determined by a nationally recognized independent
investment banking firm retained for this purpose by the Company. A "Trading
Day" means a day on which the Common Stock (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 the Common Stock.

     The purchase price for the shares of Common Stock purchased pursuant to
each Purchase Contract shall be paid by application of payments received by the
Company on the Final Settlement Date from the Collateral Agent pursuant to the
Pledge Agreement in respect of the principal of the Pledged Securities Pledged
to secure the obligations of the relevant Holder under such Purchase Contract.
The Company shall not be obligated to issue any shares of Common Stock in
respect of a Purchase Contract or deliver any certificates therefor to the
Holder unless it shall have received payment in full of the aggregate purchase
price for the shares of Common Stock to be purchased thereunder in the manner
herein set forth.

     Subject to the next succeeding paragraph, the Company shall pay, on each
Payment Date, the Contract Fee payable in respect of each Purchase Contract to
the Person in whose name the Security Certificate evidencing such Purchase
Contract is registered at the close of business on the Record Date next
preceding such Payment Date. Contract Fees will be payable at the office of the
Agent in the City of _________________ or, at the option of the Company, by
check mailed to the address of the Person entitled thereto at such address as it
appears on the Security Register.

     The Company shall have the right, at any time prior to the Final Settlement
Date, to defer the payment of any or all of the Contract Fees otherwise payable
on any Payment Date, but only if the Company shall give the Holders and the
Agent written notice of its election to defer such payment (specifying the
amount to be deferred) as provided in the

                                     Ex A-3



Purchase Contract Agreement. Any Contract Fees so deferred shall bear additional
Contract Fees thereon at the rate of per annum (computed on the basis of the
actual number of days elapsed in a year of 365 or 366 days, as the case may be),
compounding on each succeeding Payment Date, until paid in full. Deferred
Contract Fees (and additional Contract Fees accrued thereon) shall be due on the
next succeeding Payment Date except to the extent that payment is deferred
pursuant to the Purchase Contract Agreement. No Contract Fees may be deferred to
a date that is after the Final Settlement Date.

     The Purchase Contracts and the obligations and rights of the Company and
the Holders thereunder, including, without limitation, the rights of the Holders
to receive and the obligation of the Company to pay any Contract Fee, shall
immediately and automatically terminate, without the necessity of any notice or
action by any Holder, the Agent or the Company, if, on or prior to the Final
Settlement Date, a Termination Event shall have occurred. Upon the occurrence of
a Termination Event, the Company shall give written notice to the Agent and to
the Holders, at their addresses as they appear in the Security Register. Upon
and after the occurrence of a Termination Event, the Collateral Agent shall
release the Pledged Securities from the Pledge. The Securities shall thereafter
represent the right to receive the Pledged Securities forming a part of such
Securities in accordance with the provisions of the Purchase Contract Agreement
and the Pledge Agreement.

     Subject to and upon compliance with the provisions of the Purchase Contract
Agreement at the option of the Holder thereof, Purchase Contracts underlying
securities having an aggregate Stated Amount equal to $_________ or an integral
multiple thereof may be settled early ("Early Settlement") as provided in the
Purchase Contract Agreement. In order to exercise the right to effect Early
Settlement with respect to any Purchase Contracts evidenced by this Security
Certificate, the Holder of this Security Certificate shall deliver this Security
Certificate to the Agent at the Corporate Trust Office duly endorsed for
transfer to the Company on in blank with the form of Election to Settle Early
set forth below duly completed and accompanied by payment in the form of a
certified or cashier's check payable to the order of the Company in immediately
available funds in an amount (the "Early Settlement Amount") equal to (i) the
product of (A) the Stated Amount times (B) the number of Purchase Contracts with
respect to which the Holder has elected to effect Early Settlement minus (ii)
the aggregate amount of Contract Fees, if any, otherwise payable on or prior to
the immediately preceding Payment Date deferred at the option of the Company
pursuant to the Purchase Contract Agreement and remaining unpaid as of such
immediately preceding Payment Date plus (iii) if such delivery is made with
respect to any Purchase Contracts during the period from the close of business
on any Record Date next preceding any Payment Date to the opening of business on
such Payment Date, an amount equal to the sum of (x) the Contract Fees payable
on such Payment Date with respect to such Purchase Contracts plus (y) the
distributions with respect to the related Pledged Securities payable on such
Payment Date. Upon Early Settlement of Purchase Contracts by a Holder of the
related Securities, the Pledged Securities underlying such Securities shall be
released from the Pledge as provided in the Pledge Agreement and the Holder
shall be entitled to receive, a number of shares of Common Stock on account of
each Purchase Contract forming part of a Security as to which Early Settlement
is effected equal to the Early Settlement Rate. The Early Settlement Rate shall
initially be equal to and shall be adjusted in the same manner and at the same
time as the Settlement Rate is adjusted as provided in the Purchase Contract
Agreement.

     The Security Certificates are issuable only in registered form and only in
denominations of a single Security and any integral multiple thereof. The
transfer of any Security Certificate will be registered and Security
Certificates may be exchanged as provided in the Purchase Contract Agreement.
The Security Registrar may require a Holder, among other things, to furnish
appropriate endorsements and transfer documents permitted by the Purchase
Contract Agreement. No service charge shall be required for any such
registration of transfer or exchange, but the Company and the Agent may require
payment of a sum sufficient to cover any tax or other governmental charge
payable in connection therewith. For so long as the Purchase Contract underlying
a Security remains in effect, such Security shall not be separable into its
constituent parts, and the rights and obligations of the Holder of such Security
in respect of the Pledged Securities and Purchase Contract constituting such
Security may be transferred and exchanged only as a Security.

     Upon registration of transfer of this Security Certificate, the transferee
shall be bound (without the necessity of any other action on the part of such
transferee, except as may be required by the Agent pursuant to the Purchase
Contract Agreement), under the terms of the Purchase Contract Agreement and the
Purchase Contracts evidenced hereby and the transferor shall be released from
the obligations under the Purchase Contracts evidenced by this Security
Certificate.

                                     Ex A-4



The Company covenants and agrees, and the Holder, by his acceptance hereof,
likewise covenants and agrees, to be bound by the provisions of this paragraph.

     The Holder of this Security Certificate, by his acceptance hereof,
authorizes the Agent to enter into and perform the related Purchase Contracts
forming part of the Securities evidenced hereby on his behalf as his
attorney-in-fact, agrees to be bound by the terms and provisions thereof,
covenants and agrees to perform his obligations under such Purchase Contracts,
consents to the provisions of the Purchase Contract Agreement, authorizes the
Agent to enter into and perform the Pledged Agreement on his behalf as his
attorney-in-fact, and consents to the Pledge of the Pledged Securities
underlying this Security Certificate pursuant to the Pledge Agreement. The
Holder further covenants and agrees, that, to the extent and in the manner
provided in the Purchase Contract Agreement and the Pledge Agreement, but
subject to the terms thereof, payments in respect of principal of the Pledged
Securities on the Final Settlement Date shall be paid by the Collateral Agent to
the Company in satisfaction of such Holder's obligations under such Purchase
Contract and such Holder shall acquire no right, title or interest in such
payments.

     Subject to certain exceptions, the provisions of the Purchase Contract
Agreement may be amended with the consent of the Holders of at least a majority
of the Outstanding Securities.

     All terms used herein which are defined in the Purchase Contract Agreement
have the meanings set forth therein.

     The Purchase Contracts shall for all purposes be governed by, and construed
in accordance with, the laws of the State of New York.

     The Company, the Agent and any agent of the Company or the Agent may treat
the Person in whose name this Security Certificate is registered as the owner of
the Securities evidenced hereby for the purpose of receiving payments of
distributions on the Pledged Securities, receiving payments of Contract Fees,
performance of the Purchase Contracts and for all other purposes whatsoever,
whether or not any payments in respect thereof be overdue and notwithstanding
any notice to the contrary, and neither the Company, the Agent nor any such
agent shall be affected by notice to the contrary.

     The Purchase Contracts shall not, prior to the settlement thereof, entitle
the Holder to any of the rights of a holder of shares of Common Stock.

     A copy of the Purchase Contract Agreement is available for inspection at
the offices of the Agent.

Purchase Contract Agreement, and that the Purchase Contract Agent has received
from such Holders, and paid to the Company, the related Early Settlement Amounts
pursuant to the terms of the Purchase Contracts and the Purchase Contract

Agent be liable for any amount in excess of the value of the Pledged Collateral
Securities.

     6.02. Instructions of the Company. The Company shall have the right, by one

such direction shall not conflict with the provisions of any law or of this

to rely upon any certification, order, judgment, opinion, notice or other

telex, telegram or cable) believed by it to be genuine and correct and to have
been signed or sent by or on behalf of the proper Person or Persons (without
being required to determine the correctness of any fact stated therein), and

liability in connection with the exercise or performance of such powers and
duties.

instructions with respect to such property or funds so long as such dispute or
conflict shall continue, and the Collateral Agent shall not be or become liable
in any way to any of the undersigned for its failure or refusal to comply with
such conflicting claims, demands or instructions. The Collateral Agent shall be

demands shall have been finally determined by a court of competent jurisdiction
or settled by agreement between the conflicting parties as evidenced in a
writing, satisfactory to the Collateral Agent or (ii) the Collateral Agent shall

sufficient to save the Collateral Agent harmless from and against any and all
loss, liability or expense which the Collateral Agent may incur by reason of its

action or seek other judicial relief or orders as the Collateral Agent may deem
necessary. Notwithstanding anything contained herein to the contrary, the

contrary to law or to the terms of this Agreement, or which would in its opinion
subject it or any of its officers, employees or directors to liability.
