instrument or instruments (and the action embodied therein and evidenced
thereby) are herein sometimes referred to as the "Act" of the Holders signing
such instrument or instruments. Proof of execution of any such instrument or of
a writing appointing any such agent shall be sufficient for any purpose of this
Indenture and (subject to Section 601) conclusive in favor of the Trustee and
the Company, if made in the manner provided in this Section.

         The fact and date of the execution by any Person of any such instrument
or writing may be proved by the affidavit of a witness of such execution or by a
certificate of a notary public or other officer authorized by law to take
acknowledgments of deeds, certifying that the individual signing such instrument
or writing acknowledged to him the execution thereof. Where such execution is by
a signer acting in a capacity other than his individual capacity, such
certificate or affidavit shall also constitute sufficient proof of his
authority. The fact and date of the execution of any such instrument or writing,
or the authority of the Person executing the same, may also be proved in any
other manner which the Trustee deems sufficient.

         The ownership of Securities shall be proved by the Security Register.

         Any request, demand, authorization, direction, notice, consent, waiver
or other Act of the Holder of any Security shall bind every future Holder of the
same Security and the Holder of every Security issued upon the registration of
transfer thereof or in exchange therefor or in lieu thereof in respect of
anything done, omitted or suffered to be done by the Trustee or the Company in
reliance thereon, whether or not notation of such action is made upon such
Security.

         The Company may set any day as a record date for the purpose of
determining the Holders of Outstanding Securities of any series entitled to
give, make or take any request, demand, authorization, direction, notice,
consent, waiver or other action provided or permitted by this Indenture to be
given, made or taken by Holders of Securities of such series, provided that the
Company may not set a record date for, and the provisions of this paragraph
shall not apply with respect to, the giving or making of any notice,
declaration, request or direction referred to in the next paragraph. If any
record date is set pursuant to this paragraph, the Holders of Outstanding
Securities of the relevant series 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 principal amount of Outstanding Securities of such
series 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 cancelled and of no effect), and nothing in this paragraph shall be construed
to render ineffective any action taken by Holders of the requisite principal
amount of Outstanding Securities of the relevant series 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

                                       8
<PAGE>   16
Date to be given to the Trustee in writing and to each Holder of Securities of
the relevant series in the manner set forth in Section 106.

         The Trustee may set any day as a record date for the purpose of
determining the Holders of Outstanding Securities of any series entitled to join
in the giving or making of (i) any Notice of Default, (ii) any declaration of
acceleration referred to in Section 502, (iii) any request to institute
proceedings referred to in Section 507(2) or (iv) any direction referred to in
Section 512, in each case with respect to Securities of such series. If any
record date is set pursuant to this paragraph, the Holders of Outstanding
Securities of such series on such record date, and no other Holders, shall be
entitled to join in such notice, declaration, request or direction, 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 principal amount of Outstanding
Securities of such series on such record date. Nothing in this paragraph shall
be construed to prevent the Trustee 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 cancelled and of no effect), and nothing in this
paragraph shall be construed to render ineffective any action taken by Holders
of the requisite principal amount of Outstanding Securities of the relevant
series on the date such action is taken. Promptly after any record date is set
pursuant to this paragraph, the Trustee, at the Company's expense, shall cause
notice of such record date, the proposed action by Holders and the applicable
Expiration Date to be given to the Company in writing and to each Holder of
Securities of the relevant series in the manner set forth in Section 106.

         With respect to any record date set pursuant to this Section, the party
hereto that sets such record dates may designate any day 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 other party hereto in writing, and
to each Holder of Securities of the relevant series in the manner set forth in
Section 106, 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 party hereto that set such record date 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.

         Without limiting the foregoing, a Holder entitled hereunder to take any
action hereunder with regard to any particular Security may do so with regard to
all or any part of the principal amount of such Security or by one or more duly
appointed agents each of which may do so pursuant to such appointment with
regard to all or any part of such principal amount.

SECTION 105. Notices, Etc., to Trustee and Company.

         Any request, demand, authorization, direction, notice, consent, waiver
or Act of Holders or other document provided or permitted by this Indenture to
be made upon, given or furnished to, or filed with,

         (1) the Trustee by any Holder or by the Company shall be sufficient for
     every purpose hereunder if made, given, furnished or filed in writing to or
     with the Trustee and received at its Corporate Trust Office, or

                                       9
<PAGE>   17
         (2) the Company by the Trustee or by any Holder shall be sufficient for
     every purpose hereunder (unless otherwise herein expressly provided) if in
     writing and mailed, first-class postage prepaid, to the Company addressed
     to it at 299 Park Avenue, New York, New York 10171, to the attention
     of__________________, or at any other address previously furnished in
     writing to the Trustee by the Company.

SECTION 106. Notice to Holders; Waiver.

         Where this Indenture 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 (if any), and not earlier than the earliest date (if any),
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 Indenture 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 Trustee, 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 Trustee shall
constitute a sufficient notification for every purpose hereunder.

         Where this Indenture provides for Notice of any event to a Holder of a
Global Security, such notice shall be sufficiently given if given to the
Depositary for such Security (or its designee), pursuant to its Applicable
Procedures, not later than the latest date (if any), and not earlier than the
earliest date (if any), prescribed for the giving of such notice.

SECTION 107. Conflict with Trust Indenture Act.

         If any provision hereof limits, qualifies or conflicts with a provision
of the Trust Indenture Act which is required under such Act to be a part of and
govern this Indenture, the latter provision shall control. If any provision of
this Indenture modifies or excludes any provision of the Trust Indenture Act
which may be so modified or excluded, the latter provision shall be deemed to
apply to this Indenture as so modified or to be excluded, as the case may be.

SECTION 108. 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 109. Successors and Assigns.

         All covenants and agreements in this Indenture by the Company shall
bind its successors and assigns, whether so expressed or not.

SECTION 110. Separability Clause.

         In case any provision in this Indenture or in the Securities shall be
invalid, illegal or unenforceable, the validity, legality and enforceability of
the remaining provisions shall not in any way be affected or impaired thereby.

SECTION 111. Benefits of Indenture.

         Nothing in this Indenture 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 benefit or any legal or equitable right, remedy
or claim under this Indenture.

SECTION 112. Governing Law.

         This Indenture and the Securities shall be governed by and construed in
accordance with the law of the State of New York.

SECTION 113. Submission to Jurisdiction; Appointment of Agent for Service of
Process.

         The Company hereby appoints its ____________, acting through its office
at 299 Park Avenue, New York, New York 10171 (or such other address in the
Borough of Manhattan, The City of New York, as such agent shall furnish in
writing to the Trustee) as its authorized agent (the "Authorized Agent") upon
which process may be served in any legal action or proceeding against it with
respect to its obligations under this Indenture or the Securities of any series,
as the case may be, instituted in any federal or state court in the Borough of
Manhattan, The City of New York by the Holder of any Security, and agrees that
service of process upon the Authorized Agent, together with written notice of
said service mailed or delivered to the Company, addressed as provided in
Section 105, shall be deemed in every respect effective service of process upon
the Company in any such legal action or proceeding, and the Company hereby
irrevocably submits to the non-exclusive jurisdiction of any such court in
respect of any such legal action or proceeding and waives, to the extent it may
effectively do so, any objection it may have to the laying of the venue of any
such legal action or proceeding. Such appointment shall be irrevocable so long
as the Holders of Securities shall have any rights pursuant to the terms of the
Securities or of this Indenture until the appointment of a successor Authorized
Agent by the Company and such successor's acceptance of such appointment. The
Company reserves the right to appoint another person located, or with an office,
in the Borough of Manhattan, The City of New York, selected in its sole
discretion, as a successor Authorized Agent, and upon acceptance of such
appointment by such a successor the appointment of the prior Authorized Agent
shall terminate. If for any reason the ___________________ ceases to be able to
act as the Authorized Agent or to have an address in the Borough of Manhattan,
The City of New York, the Company will appoint a successor Authorized Agent in
accordance with the preceding sentence. The Company further agrees to take any
and all action, including the filing of any and all documents and instruments as
may be necessary to continue such designation and appointment of such agent or
successor in full force and effect for as long as required hereunder.

SECTION 114. Legal Holidays.

         In any case where any Interest Payment Date, Redemption Date or Stated
Maturity of any Security shall not be a Business Day at any Place of Payment,
then (notwithstanding any other provision of this Indenture or of the Securities
(other than a provision of any Security which specifically states that such
provision shall apply in lieu of this Section)) payment of interest or principal
(and premium, if any) need not be made at such Place of Payment on such date,
but may be made on the next succeeding Business Day at such Place of Payment
with the same force and effect as if made on the Interest Payment Date or
Redemption Date, or at the Stated Maturity.

shall bear interest at the rate of ...% per annum (to the extent that the
payment of such interest shall be legally enforceable), from the dates such
amounts are due until they are paid or made available for payment, and such
interest shall be payable on demand]. The interest so payable, and punctually
paid or duly provided for, on any Interest Payment Date will, as provided in

Predecessor Securities) is registered at the close of business on a Special
Record Date for the payment of such Defaulted Interest to be fixed by the
Trustee, notice whereof shall be given to Holders of Securities of this series
not less than 10 days prior to such Special Record Date, or be paid at any time
in any other lawful manner not inconsistent with the requirements of any
securities exchange on which the Securities of this series may be listed, and

Maturity and in such case the overdue principal and any overdue premium shall
bear interest at the rate of ....% per annum (to the extent that the payment of
such interest shall be legally enforceable), from the dates such amounts are due
until they are paid or made available for payment. Interest on any overdue
principal or premium shall be payable on demand.

         Payment of the principal of (and premium, if any) and [if applicable,
insert -- any such] interest on this Security will be made at the office or
agency of the Company maintained for that purpose in New York, New York, in such
coin or currency of the United States of America as at the time of payment is
legal tender for payment of public and private debts; provided, however, that at
the option of the Company payment of interest may be made by check mailed to the
address of the Person entitled thereto as such address shall appear in the
Security Register and, provided, further, that if this Security is a Global
Security, payment may be made pursuant to the Applicable Procedures of the
Depositary as permitted in said Indenture.

         Reference is hereby made to the further provisions of this Security set
forth on the reverse hereof, which further provisions shall for all purposes
have the same effect as if set forth at this place.

Holders of all Securities of such series, to waive compliance by the Company
with certain provisions of the Indenture and certain past defaults under the
Indenture and their consequences. Any such consent or waiver by the Holder of
this Security shall be conclusive and binding upon such Holder and upon all
future Holders of this Security and of any Security issued upon the registration
of transfer hereof or in exchange herefor or in lieu hereof, whether or not
notation of such consent or waiver is made upon this Security.

         As provided in and subject to the provisions of the Indenture, the
Holder of this Security shall not have the right to institute any proceeding
with respect to the Indenture or for the appointment of a receiver or trustee or
for any other remedy thereunder, unless such Holder shall have previously given
the Trustee written notice of a continuing Event of Default with respect to the
Securities of this series, the Holders of not less than 25% in principal amount
of the Securities of this series at the time Outstanding shall have made written
request to the Trustee to institute proceedings in respect of such Event of
Default as Trustee and offered the Trustee reasonable indemnity, and the Trustee
shall not have received from the Holders of a majority in principal amount of
Securities of this series at the time Outstanding a direction inconsistent with
such request, and shall have failed to institute any such proceeding, for 60
days after receipt of such notice, request and offer of indemnity. The foregoing
shall not apply to any suit instituted by the Holder of this Security for the
enforcement of any payment of principal hereof or any premium or interest hereon
on or after the respective due dates expressed herein.

         No reference herein to the Indenture and no provision of this Security
or of the Indenture shall alter or impair the obligation of the Company, which
is absolute and unconditional, to pay the principal of and any premium and
interest on this Security at the times, place and rate, and in the coin or
currency, herein prescribed.

         No service charge shall be made for any such registration of transfer
or exchange, but the Company may require payment of a sum sufficient to cover
any tax or other governmental charge payable in connection therewith.

         Prior to due presentment of this Security for registration of transfer,

Certificate setting forth the terms of the series.

                                       21
<PAGE>   29
SECTION 303. Execution, Authentication, Delivery and Dating.

         The Securities shall be executed on behalf of the Company by any two
Authorized Officers. The signature of any of these officers on the Securities
may be manual or facsimile.

         Securities 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 Securities or did not
hold such offices at the date of such Securities.

         At any time and from time to time after the execution and delivery of
this Indenture, the Company may deliver Securities of any series executed by the
Company to the Trustee for authentication, together with a Company Order for the
authentication and delivery of such Securities, and the Trustee in accordance
with the Company Order shall authenticate and deliver such Securities. If the
form or terms of the Securities of the series have been established by or
pursuant to one or more Board Resolutions as permitted by Sections 201 and 301,
in authenticating such Securities, and accepting the additional responsibilities
under this Indenture in relation to such Securities, the Trustee shall be
entitled to receive, and (subject to Section 601) shall be fully protected in
relying upon, an Opinion of Counsel stating,

         (1) if the form of such Securities has been established by or pursuant
     to Board Resolution as permitted by Section 201, that such form has been
     established in conformity with the provisions of this Indenture;

         (2) if the terms of such Securities have been established by or
     pursuant to Board Resolution as permitted by Section 301, that such terms
     have been established in conformity with the provisions of this Indenture;
     and

         (3) that such Securities, when authenticated and delivered by the
     Trustee and issued by the Company in the manner and subject to any
     conditions specified in such Opinion of Counsel, will constitute valid and
     legally binding obligations of the Company enforceable in accordance with
     their terms, subject to bankruptcy, insolvency, fraudulent transfer,
     reorganization, moratorium and similar laws of general applicability
     relating to or affecting creditors' rights and to general equity
     principles.

If such form or terms have been so established, the Trustee shall not be
required to authenticate such Securities if the issue of such Securities
pursuant to this Indenture will affect the Trustee's own rights, duties or
immunities under the Securities and this Indenture or otherwise in a manner
which is not reasonably acceptable to the Trustee.

         Notwithstanding the provisions of Section 301 and of the preceding
paragraph, if all Securities of a series are not to be originally issued at one
time, it shall not be necessary to deliver the Officers' Certificate otherwise
required pursuant to Section 301 or the Company Order and Opinion of Counsel
otherwise required pursuant to such preceding paragraph at or prior to the
authentication of each Security of such series if such documents are delivered
at or prior to the authentication upon original issuance of the first Security
of such series to be issued.

         Each Security shall be dated the date of its authentication.

                                       22
<PAGE>   30
         No Security shall be entitled to any benefit under this Indenture or be
valid or obligatory for any purpose unless there appears on such Security a
certificate of authentication substantially in the form provided for herein
executed by the Trustee by manual signature, and such certificate upon any
Security shall be conclusive evidence, and the only evidence, that such Security
has been duly authenticated and delivered hereunder. Notwithstanding the
foregoing, if any Security shall have been authenticated and delivered hereunder
but never issued and sold by the Company, and the Company shall deliver such
Security to the Trustee for cancellation as provided in Section 309, for all
purposes of this Indenture such Security shall be deemed never to have been
authenticated and delivered hereunder and shall never be entitled to the
benefits of this Indenture.

SECTION 304. Temporary Securities.

         Pending the preparation of definitive Securities of any series, the
Company may execute, and upon Company Order the Trustee shall authenticate and
deliver, temporary Securities which are printed, lithographed, typewritten,
mimeographed or otherwise produced, in any authorized denomination,
substantially of the tenor of the definitive Securities in lieu of which they
are issued and with such appropriate insertions, omissions, substitutions and
other variations as the officers executing such Securities may determine, as
evidenced by their execution of such Securities.

         If temporary Securities of any series are issued, the Company will
cause definitive Securities of that series to be prepared without unreasonable
delay. After the preparation of definitive Securities of such series, the
temporary Securities of such series shall be exchangeable for definitive
Securities of such series upon surrender of the temporary Securities of such
series at the office or agency of the Company in a Place of Payment for that
series, without charge to the Holder. Upon surrender for cancellation of any one
or more temporary Securities of any series, the Company shall execute and the
Trustee shall authenticate and deliver in exchange therefor one or more
definitive Securities of the same series, of any authorized denominations and of
like tenor and aggregate principal amount. Until so exchanged, the temporary
Securities of any series shall in all respects be entitled to the same benefits
under this Indenture as definitive Securities of such series and tenor.

SECTION 305. Registration, Registration of Transfer and Exchange.

         The Company shall cause to be kept at the Corporate Trust Office of the
Trustee a register (the register maintained in such office and in any other
office or agency of the Company in a Place of Payment being herein sometimes
collectively referred to as the "Security Register") in which, subject to such
reasonable regulations as it may prescribe, the Company shall provide for the
registration of Securities and of transfers of Securities. The Trustee is hereby
appointed "Security Registrar" for the purpose of registering Securities and
transfers of Securities as herein provided.

         Upon surrender for registration of transfer of any Security of a series
at the office or agency of the Company in a Place of Payment for that series,
the Company shall execute, and the Trustee shall authenticate and deliver, in
the name of the designated transferee or transferees, one or more new Securities
of the same series, of any authorized denominations and of like tenor and
aggregate principal amount.

                                       23
<PAGE>   31
         At the option of the Holder, Securities of any series may be exchanged
for other Securities of the same series, of any authorized denominations and of
like tenor and aggregate principal amount, upon surrender of the Securities to
be exchanged at such office or agency. Whenever any Securities are so
surrendered for exchange, the Company shall execute, and the Trustee shall
authenticate and deliver, the Securities which the Holder making the exchange is
entitled to receive.

         All Securities issued upon any registration of transfer or exchange of
Securities shall be the valid obligations of the Company, evidencing the same
debt, and entitled to the same benefits under this Indenture, as the Securities
surrendered upon such registration of transfer or exchange.

         Every Security presented or surrendered for registration of transfer or
for exchange shall (if so required by the Company or the Trustee) be duly
endorsed, or be accompanied by a written instrument of transfer in form
satisfactory to the Company and the Security Registrar 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 Securities, but the Company may require payment 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 Securities, other than
exchanges pursuant to Section 304, 906 or 1107 not involving any transfer.

         If the Securities of any series (or of any series and specified tenor)
are to be redeemed in part, the Company shall not be required (A) to issue,
register the transfer of or exchange any Securities of that series (or of that
series and specified tenor, as the case may be) during a period beginning at the
opening of business 15 days before the day of the mailing of a notice of
redemption of any such Securities selected for redemption under Section 1103 and
ending at the close of business on the day of such mailing, or (B) to register
the transfer of or exchange any Security so selected for redemption in whole or
in part, except the unredeemed portion of any Security being redeemed in part.

         The provisions of Clauses (1), (2), (3) (4) and (5) below shall apply
only to Global Securities:

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

         (2) Notwithstanding any other provision in this Indenture, and subject
     to such applicable provisions, if any, as may be specified as contemplated
     by Section 301, no Global Security may be exchanged in whole or in part for
     Securities registered, and no transfer of a Global Security in whole or in
     part may be registered, in the name of any Person other than the Depositary
     for such Global Security or a nominee thereof unless (A) such Depositary
     (i) has notified the Company that it is unwilling or unable to continue as
     Depositary for such Global Security or (ii) has ceased to be a clearing
     agency registered under the Exchange Act, (B) there shall have occurred and
     be continuing an Event of Default with respect to such Global Security or
     (C) there shall exist such circumstances, if any, in addition to or in lieu
     of the foregoing as have been specified for this purpose as contemplated by
     Section 301.

                                       24
<PAGE>   32
         (3) Subject to Clause (2) above and to such applicable provisions, if
     any, as may be specified as contemplated by Section 301, any exchange of a
     Global Security for other Securities may be made in whole or in part, and
     all Securities issued in exchange for a Global Security or any portion
     thereof shall be registered in such names as the Depositary for such Global
     Security shall direct.

         (4) Every Security authenticated and delivered upon registration of
     transfer of, or in exchange for or in lieu of, a Global Security or any
     portion thereof, whether pursuant to this Section, Section 304, 306, 906 or
     1107 or otherwise, shall be authenticated and delivered in the form of, and
     shall be, a Global Security, unless such Security is registered in the name
     of a Person other than the Depositary for such Global Security or a nominee
     thereof.

         (5) Except for the exchange rights provided in Clause (2) above, owners
     of beneficial interest in a Global Security held on their behalf by a
     Depositary shall not be entitled to receive physical delivery of Securities
     in definitive form, shall not be considered the Holders thereof for any
     purpose under this Indenture and shall have no rights under this Indenture
     with respect to such Global Security, and such Depositary may be treated by
     the Company, the Trustee and any agent of any of them as the Holder and
     owner of such Global Security for all purposes whatsoever. Notwithstanding
     the foregoing, the Depositary for any Global Security may grant proxies and
     otherwise authorize any person, including the beneficial owners of interest
     in such Global Security, to take any action which a Holder is entitled to
     take under this Indenture with respect to such Global Security.

SECTION 306. Mutilated, Destroyed, Lost and Stolen Securities.

         If any mutilated Security is surrendered to the Trustee, the Company
shall execute and the Trustee shall authenticate and deliver in exchange
therefor a new Security of the same series and of like tenor and principal
amount and bearing a number not contemporaneously outstanding.

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

         In case any such mutilated, destroyed, lost or stolen Security has
become or is about to become due and payable, the Company in its discretion may,
instead of issuing a new Security, pay such Security.

         Upon the issuance of any new Security under this Section, the Company
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 Trustee) connected therewith.

         Every new Security of any series issued pursuant to this Section in
lieu of any destroyed, lost or stolen Security shall constitute an original
additional contractual obligation of the Company, whether or not the destroyed,
lost or stolen Security shall be at any time enforceable by

                                       25
<PAGE>   33
anyone, and shall be entitled to all the benefits of this Indenture equally and
proportionately with any and all other Securities of that series duly issued
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
payment of mutilated, destroyed, lost or stolen Securities.

SECTION 307. Payment of Interest; Interest Rights Preserved.

         Except as otherwise provided as contemplated by Section 301 with
respect to any series of Securities, interest on any Security which is payable,
and is punctually paid or duly provided for, on any Interest Payment Date shall
be paid to the Person in whose name that Security (or one or more Predecessor
Securities) is registered at the close of business on the Regular Record Date
for such interest.

         Any interest on any Security of any series which is payable, but is not
punctually paid or duly provided for, on any Interest Payment Date (herein
called "Defaulted Interest") shall forthwith cease to be payable to the Holder
on the relevant Regular Record Date by virtue of having been such Holder, and
such Defaulted Interest may be paid by the Company, at its election in each
case, as provided in Clause (1) or (2) below:

         (1) The Company may elect to make payment of any Defaulted Interest to
     the Persons in whose names the Securities of such series (or their
     respective Predecessor Securities) are registered at the close of business
     on a Special Record Date for the payment of such Defaulted Interest, which
     shall be fixed in the following manner. The Company shall notify the
     Trustee in writing of the amount of Defaulted Interest proposed to be paid
     on each Security of such series and the date of the proposed payment, and
     at the same time the Company shall deposit with the Trustee an amount of
     money equal to the aggregate amount proposed to be paid in respect of such
     Defaulted Interest or shall make arrangements satisfactory to the Trustee
     for such deposit prior to the date of the proposed payment, such money when
     deposited to be held in trust for the benefit of the Persons entitled to
     such Defaulted Interest as in this Clause provided. Thereupon the Trustee
     shall fix a Special Record Date for the payment of such Defaulted Interest
     which shall be not more than 15 days and not less than 10 days prior to the
     date of the proposed payment and not less than 10 days after the receipt by
     the Trustee of the notice of the proposed payment. The Trustee shall
     promptly notify the Company of such Special Record Date and, in the name
     and at the expense of the Company, shall cause notice of the proposed
     payment of such Defaulted Interest and the Special Record Date therefor to
     be given to each Holder of Securities of such series in the manner set
     forth in Section 106, not less than 10 days prior to such Special Record
     Date. Notice of the proposed payment of such Defaulted Interest and the
     Special Record Date therefor having been so mailed, such Defaulted Interest
     shall be paid to the Persons in whose names the Securities of such series
     (or their respective Predecessor Securities) are registered at the close of
     business on such Special Record Date and shall no longer be payable
     pursuant to the following Clause (2).

         (2) The Company may make payment of any Defaulted Interest on the
     Securities of any series in any other lawful manner not inconsistent with
     the requirements of any securities exchange on which such Securities may be
     listed, and upon such notice as may be required by

                                       26
<PAGE>   34
     such exchange, if, after notice given by the Company to the Trustee of the
     proposed payment pursuant to this Clause, such manner of payment shall be
     deemed practicable by the Trustee.

         Subject to the foregoing provisions of this Section, each Security
delivered under this Indenture upon registration of transfer of or in exchange
for or in lieu of any other Security shall carry the rights to interest accrued
and unpaid, and to accrue, which were carried by such other Security.

         In the case of any Security which is converted after any Regular Record
Date and on or prior to the next succeeding Interest Payment Date (other than
any Security whose Maturity is prior to such Interest Payment Date), interest
whose Stated Maturity is on such Interest Payment Date shall be payable on such
Interest Payment Date notwithstanding such conversion, and such interest
(whether or not punctually paid or duly provided for) shall be paid to the
Person in whose name that Security (or one or more Predecessor Securities) is
registered at the close of business on such Regular Record Date. Except as
otherwise expressly provided in the immediately preceding sentence, in the case
of any Security which is converted, interest whose Stated Maturity is after the
date of conversion of such Security shall not be payable. Notwithstanding the
foregoing, the terms of any Security that may be converted may provide that the
provisions of this paragraph do not apply, or apply with such additions, changes
or omissions as may be provided thereby, to such Security.

SECTION 308. Persons Deemed Owners.

         Prior to due presentment of a Security for registration of transfer,
the Company, the Trustee and any agent of the Company or the Trustee may treat
the Person in whose name such Security is registered as the owner of such
Security for the purpose of receiving payment of principal of and any premium
and (subject to Section 307) any interest on such Security and for all other
purposes whatsoever, whether or not such Security be overdue, and neither the
Company, the Trustee nor any agent of the Company or the Trustee shall be
affected by notice to the contrary.

SECTION 309. Cancellation.

         All Securities surrendered for payment, redemption, registration of
transfer or exchange or for credit against any sinking fund payment shall, if
surrendered to any Person other than the Trustee, be delivered to the Trustee
and shall be promptly cancelled by it. The Company may at any time deliver to
the Trustee for cancellation any Securities previously authenticated and
delivered hereunder which the Company may have acquired in any manner
whatsoever, and may deliver to the Trustee (or to any other Person for delivery
to the Trustee) for cancellation any Securities previously authenticated
hereunder which the Company has not issued and sold, and all Securities so
delivered shall be promptly cancelled by the Trustee. No Securities shall be
authenticated in lieu of or in exchange for any Securities cancelled as provided
in this Section, except as expressly permitted by this Indenture. All cancelled
Securities held by the Trustee shall be disposed of as directed by a Company
Order.

                                       27
<PAGE>   35
SECTION 310. Computation of Interest.

         Except as otherwise specified as contemplated by Section 301 for
Securities of any series, interest on the Securities of each series shall be
computed on the basis of a 360-day year of twelve 30-day months.

SECTION 311. CUSIP Numbers

         The Company in issuing the Securities may use CUSIP numbers (if then
generally in use) and, if so, the Trustee shall use CUSIP numbers in notices of
redemption as a convenience to Holders, provided that any such notice may state
that no representation is made as to the correctness of such numbers either as
printed on the Securities or as contained in any notice of redemption and that
reliance may be placed only on the other identification numbers printed on the
Securities. Any such redemption shall not be affected by any defect in or
omission of such numbers.

                                  ARTICLE FOUR

                           SATISFACTION AND DISCHARGE

SECTION 401. Satisfaction and Discharge of Indenture.

         This Indenture shall upon Company Request cease to be of further effect
(except as to any surviving rights of registration of transfer or exchange of
Securities herein expressly provided for), and the Trustee, at the expense of
the Company, shall execute, without recourse, representation or warranty of any
kind, proper instruments acknowledging satisfaction and discharge of this
Indenture, when

         (1) either

                  (A) all Securities theretofore authenticated and delivered
         (other than (i) Securities which have been destroyed, lost or stolen
         and which have been replaced or paid as provided in Section 306 and
         (ii) Securities for whose payment money has theretofore been deposited
         in trust or segregated and held in trust by the Company and thereafter
         repaid to the Company or discharged from such trust, as provided in
         Section 1003) have been delivered to the Trustee for cancellation; or

                  (B) all such Securities not theretofore delivered to the
         Trustee for cancellation

                           (i) have become due and payable, or

                           (ii) will become due and payable at their Stated
                  Maturity within one year, or

                           (iii) are to be called for redemption within one year
                  under arrangements satisfactory to the Trustee for the giving
                  of notice of redemption by the Trustee in the name, and at the
                  expense, of the Company,

                                       28
<PAGE>   36
           and the Company, in the case of (i), (ii) or (iii) above, has
           deposited or caused to be deposited with the Trustee as trust funds
           in trust for the purpose money in an amount sufficient to pay and
           discharge the entire indebtedness on such Securities not theretofore
           delivered to the Trustee for cancellation, for principal and any
           premium and interest to the date of such deposit (in the case of
           Securities which have become due and payable) or to the Stated
           Maturity or Redemption Date, as the case may be;

         (2) the Company has paid or caused to be paid all other sums payable
     hereunder by the Company; and

         (3) the Company has delivered to the Trustee an Officers' Certificate
     and an Opinion of Counsel, each stating that all conditions precedent
     herein provided for relating to the satisfaction and discharge of this
     Indenture have been complied with.

         Notwithstanding the satisfaction and discharge of this Indenture, the
obligations of the Company to the Trustee under Section 607, the obligations of
the Trustee to any Authenticating Agent under Section 614 and, if money shall
have been deposited with the Trustee pursuant to subclause (B) of Clause (1) of
this Section, the obligations of the Trustee under Section 402 and the last
paragraph of Section 1003 shall survive.

SECTION 402. Application of Trust Money.

         Subject to the provisions of the last paragraph of Section 1003, all
money deposited with the Trustee pursuant to Section 401 shall be held in trust
and applied by it, in accordance with the provisions of the Securities and this
Indenture, to the payment, either directly or through any Paying Agent
(including the Company acting as its own Paying Agent) as the Trustee may
determine, to the Persons entitled thereto, of the principal and any premium and
interest for whose payment such money has been deposited with the Trustee.

                                    REMEDIES

SECTION 501. Events of Default.

         "Event of Default", wherever used herein with respect to Securities of
any series, means any one of the following events (whatever the reason for such
Event of Default and whether it shall be voluntary or involuntary or be effected
by operation of law or pursuant to any judgment, decree or order of any court or
any order, rule or regulation of any administrative or governmental body):

         (1) default in the payment of any interest upon any Security of that
     series when it becomes due and payable, and continuance of such default for
     a period of 30 days; or

         (2) default in the payment of the principal of or any premium on any
     Security of that series at its Maturity no grace period; or

<PAGE>   37
         (3) default in the deposit of any sinking fund payment, when and as due
     by the terms of a Security of that series; or

         (4) default in the performance, or breach, of any covenant or warranty
     of the Company in this Indenture (other than a covenant or warranty a
     default in whose performance or whose breach is elsewhere in this Section
     specifically dealt with or which has expressly been included in this
     Indenture solely for the benefit of series of Securities other than that
     series), and continuance of such default or breach for a period of 60 days
     after there has been given, by registered or certified mail, to the Company
     by the Trustee or to the Company and the Trustee by the Holders of at least
     10% in principal amount of the Outstanding Securities of that series a
     written notice specifying such default or breach and requiring it to be
     remedied and stating that such notice is a "Notice of Default" hereunder;
     or

         (5) the entry by a court having jurisdiction in the premises of (A) a
     decree or order for relief in respect of the Company in an involuntary case
     or proceeding under any applicable Swiss bankruptcy, insolvency,
     reorganization or other similar law or (B) a decree or order appointing a
     custodian, receiver, liquidator, assignee, trustee, sequestrator or other
     similar official of the Company or of any substantial part of its property,
     or ordering the winding up or liquidation of its affairs, and the
     continuance of any such decree or order for relief or any such other decree
     or order unstayed and in effect for a period of 60 consecutive days; or

         (6) the commencement by the Company of a voluntary case or proceeding
     under any applicable Swiss bankruptcy, insolvency, reorganization or other
     similar law or of any other case or proceeding to be adjudicated a bankrupt
     or insolvent, or the consent by it to the entry of a decree or order for
     relief in respect of the Company in an involuntary case or proceeding under
     any applicable Swiss bankruptcy, insolvency, reorganization or other
     similar law or to the commencement of any bankruptcy or insolvency case or
     proceeding against it, or the filing by it of a petition or answer or
     consent seeking reorganization or relief under any applicable Swiss law, or
     the consent by it to the filing of such petition or to the appointment of
     or taking possession by a custodian, receiver, liquidator, assignee,
     trustee, sequestrator or other similar official of the Company or of any
     substantial part of its property, or the making by it of an assignment for
     the benefit of creditors, or the taking of corporate action by the Company
     in furtherance of any such action; or

         (7) any other Event of Default provided with respect to Securities of
     that series.

SECTION 502. Acceleration of Maturity; Rescission and Annulment.

         If an Event of Default (other than an Event of Default specified in
Section 501(5) or 501(6)) with respect to Securities of any series at the time
Outstanding occurs and is continuing, then in every such case the Trustee or the
Holders of not less than 25% in principal amount of the Outstanding Securities
of that series may declare the principal amount of all the Securities of that
series (or, if any Securities of that series are Original Issue Discount
Securities, such portion of the principal amount of such Securities as may be
specified by the terms thereof) to be due and payable immediately, by a notice
in writing to the Company (and to the Trustee if given by Holders), and upon any
such declaration such principal amount (or specified amount) shall become
immediately due and payable. If an Event of Default specified in Section 501(5)
or 501 (6) with respect to Securities of any series at the time Outstanding
occurs, the principal amount of

                                       30
<PAGE>   38
all the Securities of that series (or, if any Securities of that series are
Original Issue Discount Securities, such portion of the principal amount of such
Securities as may be specified by the terms thereof) shall automatically, and
without any declaration or other action on the part of the Trustee or any
Holder, become immediately due and payable.

         At any time after such a declaration of acceleration with respect to
Securities of any series has been made and before a judgment or decree for
payment of the money due has been obtained by the Trustee as hereinafter in this
Article provided, the Holders of a majority in principal amount of the
Outstanding Securities of that series, by written notice to the Company and the
Trustee, may rescind and annul such declaration and its consequences if

         (1) the Company has paid or deposited with the Trustee a sum sufficient
     to pay

                  (A) all overdue interest on all Securities of that series,

                  (B) the principal of (and premium, if any, on) any Securities
         of that series which have become due otherwise than by such declaration
         of acceleration and any interest thereon at the rate or rates
         prescribed therefor in such Securities,

                  (C) to the extent that payment of such interest is lawful,
         interest upon overdue interest at the rate or rates prescribed therefor
         in such Securities, and

                  (D) all sums paid or advanced by the Trustee hereunder and the
         reasonable compensation, expenses, disbursements and advances of the
         Trustee, its agents and counsel;

          and

         (2) all Events of Default with respect to Securities of that series,
     other than the non-payment of the principal of Securities of that series
     which have become due solely by such declaration of acceleration, have been
     cured or waived as provided in Section 513.

         No such rescission shall affect any subsequent default or impair any
right consequent thereon.

SECTION 503. Collection of Indebtedness and Suits for Enforcement by Trustee.

         The Company covenants that if

         (1) default is made in the payment of any interest on any Security when
     such interest becomes due and payable and such default continues for a
     period of 30 days, or

         (2) default is made in the payment of the principal of (or premium, if
     any, on) any Security at the Maturity thereof,

the Company will, upon demand of the Trustee, pay to it, for the benefit of the
Holders of such Securities, the whole amount then due and payable on such
Securities for principal and any premium and interest and, to the extent that
payment of such interest shall be legally enforceable, interest on any overdue
principal and premium and on any overdue interest, at the rate or rates

                                       31
<PAGE>   39
prescribed therefor in such Securities, and, in addition thereto, such further
amount as shall be sufficient to cover the costs and expenses of collection,
including the reasonable compensation, expenses, disbursements and advances of
the Trustee, its agents and counsel.

         If an Event of Default with respect to Securities of any series occurs
and is continuing, the Trustee may in its discretion proceed to protect and
enforce its rights and the rights of the Holders of Securities of such series by
such appropriate judicial proceedings as the Trustee shall deem most effectual
to protect and enforce any such rights, whether for the specific enforcement of
any covenant or agreement in this Indenture or in aid of the exercise of any
power granted herein, or to enforce any other proper remedy.

SECTION 504. Trustee May File Proofs of Claim.

         In case of any judicial proceeding relative to the Company (or any
other obligor upon the Securities), its property or its creditors, the Trustee
shall be entitled and empowered, by intervention in such proceeding or
otherwise, to take any and all actions authorized under the Trust Indenture Act
in order to have claims of the Holders and the Trustee allowed in any such
proceeding. In particular, the Trustee shall be authorized to participate as a
member, voting or otherwise, of any official committee appointed on such matter,
to collect and receive any moneys or other property payable or deliverable on
any such claims and to distribute the same; and any custodian, receiver,
assignee, trustee, liquidator, sequestrator or other similar official in any
such judicial proceeding is hereby authorized by each Holder to make such
payments to the Trustee and, in the event that the Trustee shall consent to the
making of such payments directly to the Holders, to pay to the Trustee any
amount due it for the reasonable compensation, expenses, disbursements and
advances of the Trustee, its agents and counsel, and any other amounts due the
Trustee under Section 607.

         No provision of this Indenture shall be deemed to authorize the Trustee
to authorize or consent to or accept or adopt on behalf of any Holder any plan
of reorganization, arrangement, adjustment or composition affecting the
Securities or the rights of any Holder thereof or to authorize the Trustee to
vote in respect of the claim of any Holder in any such proceeding; provided,
however, that the Trustee may, on behalf of the Holders, vote for the election
of a trustee in bankruptcy or similar official and be a member of a creditors'
or other similar committee.

SECTION 505. Trustee May Enforce Claims Without Possession of Securities.

         All rights of action and claims under this Indenture or the Securities
may be prosecuted and enforced by the Trustee without the possession of any of
the Securities or the production thereof in any proceeding relating thereto, and
any such proceeding instituted by the Trustee shall be brought in its own name
as trustee of an express trust, and any recovery of judgment shall, after
provision for the payment of the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel, be for the
ratable benefit of the Holders of the Securities in respect of which such
judgment has been recovered.

SECTION 506. Application of Money Collected.

         Any money collected by the Trustee pursuant to this Article shall be
applied in the following order, at the date or dates fixed by the Trustee and,
in case of the distribution of such

                                       32
<PAGE>   40
money on account of principal or any premium or interest, upon presentation of
the Securities and the notation thereon of the payment if only partially paid
and upon surrender thereof if fully paid:

              FIRST: To the payment of all amounts due the Trustee under Section
     607; and

              SECOND: To the payment of the amounts then due and unpaid for
     principal of and any premium and interest on the Securities in respect of
     which or for the benefit of which such money has been collected, ratably,
     without preference or priority of any kind, according to the amounts due
     and payable on such Securities for principal and any premium and interest,
     respectively.

SECTION 507. Limitation on Suits.

         No Holder of any Security of any series shall have any right to
institute any proceeding, judicial or otherwise, with respect to this Indenture,
or for the appointment of a receiver or trustee, or for any other remedy
hereunder, unless

         (1) such Holder has previously given written notice to the Trustee of a
     continuing Event of Default with respect to the Securities of that series;

         (2) the Holders of not less than 25% in principal amount of the
     Outstanding Securities of that series shall have made written request to
     the Trustee to institute proceedings in respect of such Event of Default in
     its own name as Trustee hereunder;

         (3) such Holder or Holders have offered to the Trustee reasonable
     indemnity against the costs, expenses and liabilities to be incurred in
     compliance with such request;

         (4) the Trustee for 60 days after its receipt of such notice, request
     and offer of indemnity has failed to institute any such proceeding; and

         (5) no direction inconsistent with such written request has been given
     to the Trustee during such 60-day period by the Holders of a majority in
     principal amount of the Outstanding Securities of that series;

it being understood and intended that no one or more of such Holders shall have
any right in any manner whatever by virtue of, or by availing of, any provision
of this Indenture to affect, disturb or prejudice the rights of any other of
such Holders, or to obtain or to seek to obtain priority or preference over any
other of such Holders or to enforce any right under this Indenture, except in
the manner herein provided and for the equal and ratable benefit of all of such
Holders.

SECTION 508. Unconditional Right of Holders to Receive Principal, Premium and
Interest and to Convert.

         Notwithstanding any other provision in this Indenture, the Holder of
any Security shall have the right, which is absolute and unconditional, to
receive payment of the principal of and any premium and (subject to Section 307)
interest on such Security on the respective Stated Maturities expressed in such
Security (or, in the case of redemption, on the Redemption Date), and, if the
terms of such Security so provide, to convert such Security in accordance with
its

                                       33
<PAGE>   41
terms, and to institute suit for the enforcement of any such payment and, if
applicable, any such right to convert, and such rights shall not be impaired
without the consent of such Holder.

SECTION 509. Restoration of Rights and Remedies.

         If the Trustee or any Holder has instituted any proceeding to enforce
any right or remedy under this Indenture and such proceeding has been
discontinued or abandoned for any reason, or has been determined adversely to
the Trustee or to such Holder, then and in every such case, subject to any
determination in such proceeding, the Company, the Trustee and the Holders shall
be restored severally and respectively to their former positions hereunder and
thereafter all rights and remedies of the Trustee and the Holders shall continue
as though no such proceeding had been instituted.

SECTION 510. Rights and Remedies Cumulative.

         Except as otherwise provided with respect to the replacement or payment
of mutilated, destroyed, lost or stolen Securities in the last paragraph of
Section 306, no right or remedy herein conferred upon or reserved to the Trustee
or to the Holders is intended to be exclusive of any other right or remedy, and
every right and remedy shall, to the extent permitted by law, be cumulative and
in addition to every other right and remedy given hereunder or now or hereafter
existing at law or in equity or otherwise. The assertion or employment of any
right or remedy hereunder, or otherwise, shall not prevent the concurrent
assertion or employment of any other appropriate right or remedy.

SECTION 511. Delay or Omission Not Waiver.

         No delay or omission of the Trustee or of any Holder of any Securities
to exercise any right or remedy accruing upon any Event of Default shall impair
any such right or remedy or constitute a waiver of any such Event of Default or
an acquiescence therein. Every right and remedy given by this Article or by law
to the Trustee or to the Holders may be exercised from time to time, and as
often as may be deemed expedient, by the Trustee or by the Holders, as the case
may be.

SECTION 512. Control by Holders.

         The Holders of a majority in principal amount of the Outstanding
Securities of any series shall have the right to direct the time, method and
place of conducting any proceeding for any remedy available to the Trustee, or
exercising any trust or power conferred on the Trustee, with respect to the
Securities of such series, provided that

         (1) such direction shall not be in conflict with any rule of law or
     with this Indenture, and

         (2) the Trustee may take any other action deemed proper by the Trustee
     which is not inconsistent with such direction.

                                       34
<PAGE>   42

SECTION 513.     Waiver of Past Defaults.

         The Holders of not less than a majority in principal amount of the
Outstanding Securities of any series may on behalf of the Holders of all the
Securities of such series waive any past default hereunder with respect to such
series and its consequences, except a default

(1)  in the payment of the principal of or any premium or interest on any
     Security of such series, or

(2)  in respect of a covenant or provision hereof which under Article Nine
     cannot be modified or amended without the consent of the Holder of each
     Outstanding Security of such series affected.

         Upon any such waiver, such default shall cease to exist, and any Event
of Default arising therefrom shall be deemed to have been cured, for every
purpose of this Indenture; but no such waiver shall extend to any subsequent or
other default or impair any right consequent thereon.

SECTION 514.    Undertaking for Costs.

         In any suit for the enforcement of any right or remedy under this
Indenture, or in any suit against the Trustee for any action taken, suffered or
omitted by it as Trustee, a court may require any party litigant in such suit to
file an undertaking to pay the costs of such suit, and may assess costs against
any such party litigant, in the manner and to the extent provided in the Trust
Indenture Act; provided that neither this Section nor the Trust Indenture Act
shall be deemed to authorize any court to require such an undertaking or to make
such an assessment in any suit instituted by the Company.

SECTION 515.    Waiver of Usury, Stay or Extension Laws.

         The Company covenants (to the extent that it may lawfully do so) that
it will not at any time insist upon, or plead, or in any manner whatsoever claim
or take the benefit or advantage of, any usury, stay or extension law wherever
enacted, now or at any time hereafter in force, which may affect the covenants
or the performance of this Indenture; and the Company (to the extent that it may
lawfully do so) hereby expressly waives all benefit or advantage of any such law
and covenants that it will not hinder, delay or impede the execution of any
power herein granted to the Trustee, but will suffer and permit the execution of
every such power as though no such law had been enacted.

                                  ARTICLE SIX

                                   THE TRUSTEE

SECTION 601.    Certain Duties and Responsibilities.

         The duties and responsibilities of the Trustee shall be as provided by
the Trust Indenture Act. Notwithstanding the foregoing, no provision of this
Indenture shall require the Trustee to expend or risk its own funds or otherwise
incur any financial liability 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

                                       35
<PAGE>   43

grounds for believing that repayment of such funds or adequate indemnity against
such risk or liability is not reasonably assured to it. Whether or not therein
expressly so provided, every provision of this Indenture relating to the conduct
or affecting the liability of or affording protection to the Trustee shall be
subject to the provisions of this Section.

SECTION 602.    Notice of Defaults.

         If a default occurs hereunder with respect to Securities of any series,
the Trustee shall give the Holders of Securities of such series notice of such
default as and to the extent provided by the Trust Indenture Act; provided,
however, that in the case of any default of the character specified in Section
501(4) with respect to Securities of such series, no such notice to Holders
shall be given until at least 30 days after the occurrence thereof. For the
purpose of this Section, the term "default" means any event which is, or after
notice or lapse of time or both would become, an Event of Default with respect
to Securities of such series.

SECTION 603.    Certain Rights of Trustee.

         Subject to the provisions of Section 601:

          (1) the Trustee may rely and shall be protected in acting or
     refraining from acting upon any resolution, certificate, statement,
     instrument, opinion, report, notice, request, direction, consent, order,
     bond, debenture, note, other evidence of indebtedness or other paper or
     document believed by it to be genuine and to have been signed or presented
     by the proper party or parties;

          (2) any request or direction of the Company mentioned herein shall be
     sufficiently evidenced by a Company Request or Company Order, and any
     resolution of the Board of Directors shall be sufficiently evidenced by a
     Board Resolution;

          (3) whenever in the administration of this Indenture the Trustee shall
     deem it desirable that a matter be proved or established prior to taking,
     suffering or omitting any action hereunder, the Trustee (unless other
     evidence be herein specifically prescribed) may, in the absence of bad
     faith on its part, rely upon an Officers' Certificate;

          (4) the Trustee may consult with counsel and the written advice of
     such counsel or any Opinion of Counsel shall be full and complete
     authorization and protection in respect of any action taken, suffered or
     omitted by it hereunder in good faith and in reliance thereon;

          (5) the Trustee shall be under no obligation to exercise any of the
     rights or powers vested in it by this Indenture at the request or direction
     of any of the Holders pursuant to this Indenture, unless such Holders shall
     have offered to the Trustee reasonable security or indemnity against the
     costs, expenses and liabilities which might be incurred by it in compliance
     with such request or direction;

          (6) the Trustee shall not be bound to make any investigation into the
     facts or matters stated in any resolution, certificate, statement,
     instrument, opinion, report, notice, request, direction, consent, order,
     bond, debenture, note, other evidence of indebtedness or other paper or
     document, but the Trustee, in its discretion, may make such further inquiry
     or investigation into such facts or matters as it may see fit, and, if the
     Trustee shall determine to make such

                                       36
<PAGE>   44

     further inquiry or investigation, it shall be entitled to examine the
     books, records and premises of the Company, personally or by agent or
     attorney;

          (7) the Trustee may execute any of the trusts or powers hereunder or
     perform any duties hereunder either directly or by or through agents or
     attorneys and the Trustee shall not be responsible for any misconduct or
     negligence on the part of any agent or attorney appointed with due care by
     it hereunder;

          (8) the Trustee shall not be liable for any action taken, suffered or
     omitted by it in good faith and believed by it to be authorized or within
     the discretion or rights or powers conferred upon it by this Indenture; and

          (9) except during the continuance of an Event of Default, the Trustee
     need perform only those duties as are specifically set forth in this
     Indenture.

         The Trustee shall not be required to expend or risk its own funds or
otherwise incur any financial liability 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.

         In the event that an Event of Default has occurred and is continuing,
the Trustee shall, in the exercise of its power, use the degree of care of a
prudent person in similar circumstances in the conduct of his or her own
affairs.

SECTION 604.    Not Responsible for Recitals or Issuance of Securities.

         The recitals contained herein and in the Securities, except the
Trustee's certificates of authentication, shall be taken as the statements of
the Company, and neither the Trustee nor any Authenticating Agent assumes any
responsibility for their correctness. The Trustee makes no representations as to
the validity or sufficiency of this Indenture or of the Securities. Neither the
Trustee nor any Authenticating Agent shall be accountable for the use or
application by the Company of Securities or the proceeds thereof.

SECTION 605.    May Hold Securities.

         The Trustee, any Authenticating Agent, any Paying Agent, any Security
Registrar or any other agent of the Company, in its individual or any other
capacity, may become the owner or pledgee of Securities and, subject to Sections
608 and 613, may otherwise deal with the Company with the same rights it would
have if it were not Trustee, Authenticating Agent, Paying Agent, Security
Registrar or such other agent.

SECTION 606.    Money Held in Trust.

         Money held by the Trustee in trust hereunder need not be segregated
from other funds except to the extent required by law. The Trustee shall be
under no liability for interest on any money received by it hereunder except as
otherwise agreed with the Company.

                                       37
<PAGE>   45

SECTION 607.    Compensation and Reimbursement.

         The Company agrees

          (1) to pay to the Trustee from time to time reasonable compensation
     for all services rendered by it hereunder (which compensation shall not be
     limited by any provision of law in regard to the compensation of a trustee
     of an express trust);

          (2) except as otherwise expressly provided herein, to reimburse the
     Trustee upon its request for all reasonable expenses, disbursements and
     advances incurred or made by the Trustee in accordance with any provision
     of this Indenture (including the reasonable compensation and the expenses
     and disbursements of its agents and counsel), except any such expense,
     disbursement or advance as may be attributable to its negligence or bad
     faith; and

          (3) to indemnify the Trustee for, and to hold it harmless against, any
     loss, liability or expense incurred without negligence or bad faith on its
     part, arising out of or in connection with the acceptance or administration
     of the trust or trusts hereunder, including the costs and expenses of
     enforcing this Indenture against the Company (including Section 607) and
     defending itself against any claim, whether asserted by any Holder or the
     Company, or liability in connection with the exercise or performance of any
     of its powers or duties hereunder.

         To secure the Company's payment obligations in this Section 607, the
Trustee shall have a lien prior to the Securities on all money or property held
or collected by the Trustee, except that held in trust to pay the principal
amount, premium, if any, or interest, if any, as the case may be, on particular
Securities.

         The Company's payment obligations pursuant to this Section 607 shall
survive the discharge of this Indenture. When the Trustee incurs expenses after
the occurrence of a Default specified in Section 501(5) or (6), the expenses are
intended to constitute expenses of administration under any applicable law.

SECTION 608.    Conflicting Interests.

         If the Trustee has or shall acquire a conflicting interest within the
meaning of the Trust Indenture Act, the Trustee shall either eliminate such
interest or resign, to the extent and in the manner provided by, and subject to
the provisions of, the Trust Indenture Act and this Indenture. To the extent
permitted by such Act, the Trustee shall not be deemed to have a conflicting
interest by virtue of being a trustee under this Indenture with respect to
Securities of more than one series [or a trustee under -- list here any prior
indentures between the Company and the Trustee that have not been satisfied and
discharged and that may be excluded by the proviso to Section 310(b)(1) of the
Trust Indenture Act].

SECTION 609.    Corporate Trustee Required; Eligibility.

         There shall at all times be one (and only one) Trustee hereunder with
respect to the Securities of each series, which may be Trustee hereunder for
Securities of one or more other series. Each Trustee shall be a Person that is
eligible pursuant to the Trust Indenture Act to act as such, has a combined
capital and surplus of at least $50,000,000 and has its Corporate Trust

                                       38
<PAGE>   46

Office in the Borough of Manhattan, The City of New York. If any such Person
publishes reports of condition at least annually, pursuant to law or to the
requirements of its supervising or examining authority, then for the purposes of
this Section and to the extent permitted by the Trust Indenture Act, the
combined capital and surplus of such Person shall be deemed to be its combined
capital and surplus as set forth in its most recent report of condition so
published. If at any time the Trustee with respect to the Securities of any
series shall cease to be eligible in accordance with the provisions of this
Section, it shall resign immediately in the manner and with the effect
hereinafter specified in this Article.

SECTION 610.    Resignation and Removal; Appointment of Successor.

         No resignation or removal of the Trustee and no appointment of a
successor Trustee pursuant to this Article shall become effective until the
acceptance of appointment by the successor Trustee in accordance with the
applicable requirements of Section 611.

         The Trustee may resign at any time with respect to the Securities of
one or more series by giving written notice thereof to the Company. If the
instrument of acceptance by a successor Trustee required by Section 611 shall
not have been delivered to the Trustee within 30 days after the giving of such
notice of resignation, the resigning Trustee may petition any court of competent
jurisdiction for the appointment of a successor Trustee with respect to the
Securities of such series.

         The Trustee may be removed at any time with respect to the Securities
of any series by Act of the Holders of a majority in principal amount of the
Outstanding Securities of such series, delivered to the Trustee and to the
Company.

         If at any time:

          (1) the Trustee shall fail to comply with Section 608 after written
     request therefor by the Company or by any Holder who has been a bona fide
     Holder of a Security for at least six months, or

          (2) the Trustee shall cease to be eligible under Section 609 and shall
     fail to resign after written request therefor by the Company or by any such
     Holder, or

          (3) the Trustee shall become incapable of acting or shall be adjudged
     a bankrupt or insolvent or a receiver of the Trustee or of its property
     shall be appointed or any public officer shall take charge or control of
     the Trustee or of its property or affairs for the purpose of
     rehabilitation, conservation or liquidation,

then, in any such case, (A) the Company by a Board Resolution may remove the
Trustee with respect to all Securities, or (B) subject to Section 514, any
Holder who has been a bona fide Holder of a Security for at least six months
may, on behalf of himself and all others similarly situated, petition any court
of competent jurisdiction for the removal of the Trustee with respect to all
Securities and the appointment of a successor Trustee or Trustees.

         If the Trustee shall resign, be removed or become incapable of acting,
or if a vacancy shall occur in the office of Trustee for any cause, with respect
to the Securities of one or more series, the Company, by a Board Resolution,
shall promptly appoint a successor Trustee or

                                       39
<PAGE>   47

Trustees with respect to the Securities of that or those series (it being
understood that any such successor Trustee may be appointed with respect to the
Securities of one or more or all of such series and that at any time there shall
be only one Trustee with respect to the Securities of any particular series) and
shall comply with the applicable requirements of Section 611. If, within one
year after such resignation, removal or incapability, or the occurrence of such
vacancy, a successor Trustee with respect to the Securities of any series shall
be appointed by Act of the Holders of a majority in principal amount of the
Outstanding Securities of such series delivered to the Company and the retiring
Trustee, the successor Trustee so appointed shall, forthwith upon its acceptance
of such appointment in accordance with the applicable requirements of Section
611, become the successor Trustee with respect to the Securities of such series
and to that extent supersede the successor Trustee appointed by the Company. If
no successor Trustee with respect to the Securities of any series shall have
been so appointed by the Company or the Holders and accepted appointment in the
manner required by Section 611, any Holder who has been a bona fide Holder of a
Security of such series for at least six months may, on behalf of himself and
all others similarly situated, petition any court of competent jurisdiction for
the appointment of a successor Trustee with respect to the Securities of such
series.

         The Company shall give notice of each resignation and each removal of
the Trustee with respect to the Securities of any series and each appointment of
a successor Trustee with respect to the Securities of any series to all Holders
of Securities of such series in the manner provided in Section 106. Each notice
shall include the name of the successor Trustee with respect to the Securities
of such series and the address of its Corporate Trust Office.

SECTION 611.    Acceptance of Appointment by Successor.

         In case of the appointment hereunder of a successor Trustee with
respect to all Securities, every such successor Trustee so appointed shall
execute, acknowledge and deliver to the Company and to the retiring Trustee an
instrument accepting such appointment, and thereupon the resignation or removal
of the retiring Trustee shall become effective and such successor Trustee,
without any further act, deed or conveyance, shall become vested with all the
rights, powers, trusts and duties of the retiring Trustee; but, on the request
of the Company or the successor Trustee, such retiring Trustee shall, upon
payment of its charges, execute and deliver an instrument transferring to such
successor Trustee all the rights, powers and trusts of the retiring Trustee and
shall duly assign, transfer and deliver to such successor Trustee all property
and money held by such retiring Trustee hereunder.

         In case of the appointment hereunder of a successor Trustee with
respect to the Securities of one or more (but not all) series, the Company, the
retiring Trustee and each successor Trustee with respect to the Securities of
one or more series shall execute and deliver an indenture supplemental hereto
wherein each successor Trustee shall accept such appointment and which (1) shall
contain such provisions as shall be necessary or desirable to transfer and
confirm to, and to vest in, each successor Trustee all the rights, powers,
trusts and duties of the retiring Trustee with respect to the Securities of that
or those series to which the appointment of such successor Trustee relates, (2)
if the retiring Trustee is not retiring with respect to all Securities, shall
contain such provisions as shall be deemed necessary or desirable to confirm
that all the rights, powers, trusts and duties of the retiring Trustee with
respect to the Securities of that or those series as to which the retiring
Trustee is not retiring shall continue to be vested in the retiring Trustee, and
(3) shall add to or change any of the provisions of this Indenture as shall be
necessary to provide for or facilitate the administration of the trusts
hereunder by more than one Trustee, it being

                                       40
<PAGE>   48

understood that nothing herein or in such supplemental indenture shall
constitute such Trustees co-trustees of the same trust and that each such
Trustee shall be trustee of a trust or trusts hereunder separate and apart from
any trust or trusts hereunder administered by any other such Trustee; and upon
the execution and delivery of such supplemental indenture the resignation or
removal of the retiring Trustee shall become effective to the extent provided
therein and each such successor Trustee, without any further act, deed or
conveyance, shall become vested with all the rights, powers, trusts and duties
of the retiring Trustee with respect to the Securities of that or those series
to which the appointment of such successor Trustee relates; but, on request of
the Company or any successor Trustee, such retiring Trustee shall duly assign,
transfer and deliver to such successor Trustee all property and money held by
such retiring Trustee hereunder with respect to the Securities of that or those
series to which the appointment of such successor Trustee relates.

         Upon request of any such successor Trustee, the Company shall execute
any and all instruments for more fully and certainly vesting in and confirming
to such successor Trustee all such rights, powers and trusts referred to in the
first or second preceding paragraph, as the case may be.

         No successor Trustee shall accept its appointment unless at the time of
such acceptance such successor Trustee shall be qualified and eligible under
this Article.

SECTION 612.    Merger, Conversion, Consolidation or Succession to Business.

         Any corporation into which the Trustee 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 Trustee shall be a party, or any
corporation succeeding to all or substantially all the corporate trust business
of the Trustee, shall be the successor of the Trustee hereunder, provided such
corporation shall be otherwise qualified and eligible under this Article,
without the execution or filing of any paper or any further act on the part of
any of the parties hereto. In case any Securities shall have been authenticated,
but not delivered, by the Trustee then in office, any successor by merger,
conversion or consolidation to such authenticating Trustee may adopt such
authentication and deliver the Securities so authenticated with the same effect
as if such successor Trustee had itself authenticated such Securities.

SECTION 613.    Preferential Collection of Claims Against Company.

         If and when the Trustee shall be or become a creditor of the Company
(or any other obligor upon the Securities), the Trustee shall be subject to the
provisions of the Trust Indenture Act regarding the collection of claims against
the Company (or any such other obligor).

SECTION 614.    Appointment of Authenticating Agent.

         The Trustee may appoint an Authenticating Agent or Agents with respect
to one or more series of Securities which shall be authorized to act on behalf
of the Trustee to authenticate Securities of such series issued upon original
issue and upon exchange, registration of transfer or partial redemption thereof
or pursuant to Section 306, and Securities so authenticated shall be entitled to
the benefits of this Indenture and shall be valid and obligatory for all
purposes as if authenticated by the Trustee hereunder. Wherever reference is
made in this Indenture to the authentication and delivery of Securities by the
Trustee or the Trustee's certificate of

                                       41
<PAGE>   49

authentication, such reference shall be deemed to include authentication and
delivery on behalf of the Trustee by an Authenticating Agent and a certificate
of authentication executed on behalf of the Trustee by an Authenticating Agent.
Each Authenticating Agent shall be acceptable to the Company and shall at all
times be a corporation organized and doing business under the laws of the United
States of America, any State thereof or the District of Columbia, authorized
under such laws to act as Authenticating Agent, having a combined capital and
surplus of not less than $50,000,000 and subject to supervision or examination
by Federal or State authority. If such Authenticating Agent publishes reports of
condition at least annually, pursuant to law or to the requirements of said
supervising or examining authority, then for the purposes of this Section, the
combined capital and surplus of such Authenticating Agent shall be deemed to be
its combined capital and surplus as set forth in its most recent report of
condition so published. If at any time an Authenticating Agent shall cease to be
eligible in accordance with the provisions of this Section, such Authenticating
Agent shall resign immediately in the manner and with the effect specified in
this Section.

         Any corporation into which an Authenticating Agent may be merged or
converted or with which it may be consolidated, or any corporation resulting
from any merger, conversion or consolidation to which such Authenticating Agent
shall be a party, or any corporation succeeding to the corporate agency or
corporate trust business of an Authenticating Agent, shall continue to be an
Authenticating Agent, provided such corporation shall be otherwise eligible
under this Section, without the execution or filing of any paper or any further
act on the part of the Trustee or the Authenticating Agent.

         An Authenticating Agent may resign at any time by giving written notice
thereof to the Trustee and to the Company. The Trustee may at any time terminate
the agency of an Authenticating Agent by giving written notice thereof to such
Authenticating Agent and to the Company. Upon receiving such a notice of
resignation or upon such a termination, or in case at any time such
Authenticating Agent shall cease to be eligible in accordance with the
provisions of this Section, the Trustee may appoint a successor Authenticating
Agent which shall be acceptable to the Company and shall give notice of such
appointment in the manner provided in Section 106 to all Holders of Securities
of the series with respect to which such Authenticating Agent will serve. Any
successor Authenticating Agent upon acceptance of its appointment hereunder
shall become vested with all the rights, powers and duties of its predecessor
hereunder, with like effect as if originally named as an Authenticating Agent.
No successor Authenticating Agent shall be appointed unless eligible under the
provisions of this Section.

         The Trustee agrees to pay to each Authenticating Agent from time to
time reasonable compensation for its services under this Section, and the
Trustee shall be entitled to be reimbursed for such payments, subject to the
provisions of Section 607.

         If an appointment with respect to one or more series is made pursuant
to this Section, the Securities of such series may have endorsed thereon, in
addition to the Trustee's certificate of authentication, an alternative
certificate of authentication in the following form:

         This is one of the Securities of the series designated therein referred
to in the within-mentioned Indenture.

                                                                    As Trustee

addresses of Holders received by the Trustee in its capacity as Security
Registrar. The Trustee may destroy any list furnished to it as provided in
Section 701 upon receipt of a new list so furnished.

         The rights of Holders to communicate with other Holders with respect to
their rights under this Indenture or under the Securities, and the corresponding
rights and privileges of the Trustee, shall be as provided by the Trust
Indenture Act.

         Every Holder of Securities, by receiving and holding the same, agrees
with the Company and the Trustee that neither the Company nor the Trustee nor
any agent of either of them shall be held accountable by reason of any
disclosure of information as to names and addresses of Holders made pursuant to
the Trust Indenture Act.

SECTION 703.    Reports by Trustee.

SECTION 704.    Reports by Company.

         The Company shall file with the Trustee and the Commission, and
transmit to Holders, such information, documents and other reports, and such
summaries thereof, as may be required pursuant to the Trust Indenture Act at the
times and in the manner provided pursuant to such Act; provided that any such
information, documents or reports required to be filed with the Commission
pursuant to Section 13 or 15(d) of the Exchange Act shall be filed with the
Trustee within 15 days after the same is so required to be filed with the
Commission.

     Default, and no event which, after notice or lapse of time or both, would
     become an Event of Default, shall have happened and be continuing;

     conveyance, transfer or lease, properties or assets of the Company would
     become subject to a mortgage, pledge, lien, security interest or other
     encumbrance which would not be permitted by this Indenture, the

Company is merged or to which such conveyance, transfer or lease is made shall
succeed to, and be substituted for, and may exercise every right and power of,
the Company under this Indenture with the same effect as if such successor
Person had been named as the Company herein, and thereafter, except in the case
of a lease, the predecessor Person shall be relieved of all obligations and
covenants under this Indenture and the Securities.

SECTION 901.    Supplemental Indentures Without Consent of Holders.

         Without the consent of any Holders, the Company, when authorized by a
Board Resolution, and the Trustee, at any time and from time to time, may enter
into one or more indentures supplemental hereto, in form satisfactory to the
Trustee, for any of the following purposes:

          (1) to evidence the succession of another Person to the Company and
     the assumption by any such successor of the covenants of the Company herein
     and in the Securities; or

          (2) to add to the covenants of the Company for the benefit of the
     Holders of all or any series of Securities (and if such covenants are to be
     for the benefit of less than all series of Securities, stating that such
     covenants are expressly being included solely for the benefit of such
     series) or to surrender any right or power herein conferred upon the
     Company; or

          (3) to add any additional Events of Default for the benefit of the
     Holders of all or any series of Securities (and if such additional Events
     of Default are to be for the benefit of less than all series of Securities,
     stating that such additional Events of Default are expressly being included
     solely for the benefit of such series); or

          (4) to add to or change any of the provisions of this Indenture to
     such extent as shall be necessary to permit or facilitate the issuance of
     Securities in bearer form, registrable or not

                                       45
<PAGE>   53

     registrable as to principal, and with or without interest coupons, or to
     permit or facilitate the issuance of Securities in uncertificated form; or

          (5) to add to, change or eliminate any of the provisions of this
     Indenture in respect of one or more series of Securities, provided that any
     such addition, change or elimination (A) shall neither (i) apply to any
     Security of any series created prior to the execution of such supplemental
     indenture and entitled to the benefit of such provision nor (ii) modify the
     rights of the Holder of any such Security with respect to such provision or
     (B) shall become effective only when there is no such Security Outstanding;
     or

          (6) to secure the Securities; or

          (7) to establish the form or terms of Securities of any series as
     permitted by Sections 201 and 301; or

          (8) to evidence and provide for the acceptance of appointment
     hereunder by a successor Trustee with respect to the Securities of one or
     more series and to add to or change any of the provisions of this Indenture
     as shall be necessary to provide for or facilitate the administration of
     the trusts hereunder by more than one Trustee, pursuant to the requirements
     of Section 611; or

          (9) to add to or change any of the provisions of this Indenture with
     respect to any Securities that by their terms may be converted into
     securities or other property other than Securities of the same series and
     of like tenor, in order to permit or facilitate the issuance, payment or
     conversion of such Securities; or

          (10) to cure any ambiguity, to correct or supplement any provision
     herein which may be defective or inconsistent with any other provision
     herein, or to make any other provisions with respect to matters or
     questions arising under this Indenture, provided that such action pursuant
     to this Clause (10) shall not adversely affect the interests of the Holders
     of Securities of any series in any material respect.

SECTION 902.    Supplemental Indentures With Consent of Holders.

         With the consent of the Holders of not less than 662/3% in principal
amount of the Outstanding Securities of each series affected by such
supplemental indenture, by Act of said Holders delivered to the Company and the
Trustee, the Company, when authorized by a Board Resolution, and the Trustee may
enter into an indenture or indentures supplemental hereto for the purpose of
adding any provisions to or changing in any manner or eliminating any of the
provisions of this Indenture or of modifying in any manner the rights of the
Holders of Securities of such series under this Indenture; provided, however,
that no such supplemental indenture shall, without the consent of the Holder of
each Outstanding Security affected thereby,

          (1) change the Stated Maturity of the principal of, or any installment
     of principal of or interest on, any Security, or reduce the principal
     amount thereof or the rate of interest thereon or any premium payable upon
     the redemption thereof, or reduce the amount of the principal of an
     Original Issue Discount Security or any other Security which would be due
     and payable upon a declaration of acceleration of the Maturity thereof
     pursuant to Section 502, or change any Place of Payment where, or the coin
     or currency in which, any

                                       46
<PAGE>   54

     Security or any premium or interest thereon is payable, or impair the right
     to institute suit for the enforcement of any such payment on or after the
     Stated Maturity thereof (or, in the case of redemption, on or after the
     Redemption Date), or modify the provisions of this Indenture with respect
     to the subordination of the Securities in a manner adverse to the Holders,
     or

          (2) if any Security provides that the Holder may require the Company
     to repurchase or convert such Security, impair such Holder's right to
     require repurchase or conversion of such Security on the terms provided
     therein, or

          (3) reduce the percentage in principal amount of the Outstanding
     Securities of any series, the consent of whose Holders is required for any
     such supplemental indenture, or the consent of whose Holders is required
     for any waiver (of compliance with certain provisions of this Indenture or
     certain defaults hereunder and their consequences) provided for in this
     Indenture, or

          (4) modify any of the provisions of this Section or Section 513,
     except to increase any such percentage or to provide that certain other
     provisions of this Indenture cannot be modified or waived without the
     consent of the Holder of each Outstanding Security affected thereby;
     provided, however, that this clause shall not be deemed to require the
     consent of any Holder with respect to changes in the references to "the
     Trustee" and concomitant changes in this Section and Section 1008, or the
     deletion of this proviso, in accordance with the requirements of Sections
     611 and 901(8).

A supplemental indenture which changes or eliminates any covenant or other
provision of this Indenture which has expressly been included solely for the
benefit of one or more particular series of Securities, or which modifies the
rights of the Holders of Securities of such series with respect to such covenant
or other provision, shall be deemed not to affect the rights under this
Indenture of the Holders of Securities of any other series.

         It shall not be necessary for any Act of Holders under this Section to
approve the particular form of any proposed supplemental indenture, but it shall
be sufficient if such Act shall approve the substance thereof.

SECTION 903.    Execution of Supplemental Indentures.

         In executing, or accepting the additional trusts created by, any
supplemental indenture permitted by this Article or the modifications thereby of
the trusts created by this Indenture, the Trustee shall be entitled to receive,
and (subject to Section 601) shall be fully protected in relying upon, an
Opinion of Counsel stating that the execution of such supplemental indenture is
authorized or permitted by this Indenture. The Trustee may, but shall not be
obligated to, enter into any such supplemental indenture which affects the
Trustee's own rights, duties or immunities under this Indenture or otherwise.

SECTION 904.    Effect of Supplemental Indentures.

         Upon the execution of any supplemental indenture under this Article,
this Indenture shall be modified in accordance therewith, and such supplemental
indenture shall form a part of this Indenture for all purposes; and every Holder
of Securities theretofore or thereafter authenticated and delivered hereunder
shall be bound thereby.

SECTION 905.    Conformity with Trust Indenture Act.

         Every supplemental indenture executed pursuant to this Article shall
conform to the requirements of the Trust Indenture Act.

SECTION 906.    Reference in Securities to Supplemental Indentures.

         Securities of any series authenticated and delivered after the
execution of any supplemental indenture pursuant to this Article may, and shall
if required by the Trustee, bear a notation in form approved by the Trustee as
to any matter provided for in such supplemental indenture. If the Company shall
so determine, new Securities of any series so modified as to conform, in the
opinion of the Trustee and the Company, to any such supplemental indenture may
be prepared and executed by the Company and authenticated and delivered by the
Trustee in exchange for Outstanding Securities of such series.

                                   ARTICLE TEN

                                    COVENANTS

SECTION 1001.   Payment of Principal, Premium and Interest.

         The Company covenants and agrees for the benefit of each series of
Securities that it will duly and punctually pay the principal of and any premium
and interest on the Securities of that series in accordance with the terms of
the Securities and this Indenture.

SECTION 1002.   Maintenance of Office or Agency.

         The Company will maintain in each Place of Payment for any series of
Securities an office or agency where Securities of that series may be presented
or surrendered for payment, where Securities of that series may be surrendered
for registration of transfer or exchange and where notices and demands to or
upon the Company in respect of the Securities of that series and this Indenture
may be served. The Company will give prompt written notice to the Trustee of the
location, and any change in the location, of such office or agency. If at any
time the Company shall fail to maintain any such required office or agency or
shall fail to furnish the Trustee with the address thereof, such presentations,
surrenders, notices and demands may be made or served at the Corporate Trust
Office of the Trustee, and the Company hereby appoints the Trustee as its agent
to receive all such presentations, surrenders, notices and demands.

         The Company may also from time to time designate one or more other
offices or agencies where the Securities of one or more series may be presented
or surrendered for any or all such purposes and may from time to time rescind
such designations; provided, however, that no such designation or rescission
shall in any manner relieve the Company of its obligation to maintain an office
or agency in each Place of Payment for Securities of any series for such
purposes. The Company will give prompt written notice to the Trustee of any such
designation or rescission and of any change in the location of any such other
office or agency.

SECTION 1003.   Money for Securities Payments to Be Held in Trust.

         If the Company shall at any time act as its own Paying Agent with
respect to any series of Securities, it will, on or before each due date of the
principal of or any premium or interest on any of the Securities of that series,
segregate and hold in trust for the benefit of the Persons entitled thereto a
sum sufficient to pay the principal and any premium and interest so becoming due
until such sums shall be paid to such Persons or otherwise disposed of as herein
provided and will promptly notify the Trustee of its action or failure so to
act.

         Whenever the Company shall have one or more Paying Agents for any
series of Securities, it will, prior to each due date of the principal of or any
premium or interest on any Securities of that series, deposit with a Paying
Agent a sum sufficient to pay such amount, such sum to be held as provided by
the Trust Indenture Act, and (unless such Paying Agent is the Trustee) the
Company will promptly notify the Trustee of its action or failure so to act.

         The Company will cause each Paying Agent for any series of Securities
other than the Trustee to execute and deliver to the Trustee an instrument in
which such Paying Agent shall agree with the Trustee, subject to the provisions
of this Section, that such Paying Agent will (1) comply with the provisions of
the Trust Indenture Act applicable to it as a Paying Agent and (2) during the
continuance of any default by the Company (or any other obligor upon the
Securities of that series) in the making of any payment in respect of the
Securities of that series, upon the written request of the Trustee, forthwith
pay to the Trustee all sums held in trust by such Paying Agent for payment in
respect of the Securities of that series.

         The Company may at any time, for the purpose of obtaining the
satisfaction and discharge of this Indenture or for any other purpose, pay, or
by Company Order direct any Paying Agent to pay, to the Trustee all sums held in
trust by the Company or such Paying Agent, such sums to be held by the Trustee
upon the same trusts as those upon which such sums were held by the Company or
such Paying Agent; and, upon such payment by any Paying Agent to the Trustee,
such Paying Agent shall be released from all further liability with respect to
such money.

         Any money deposited with the Trustee or any Paying Agent, or then held
by the Company, in trust for the payment of the principal of or any premium or
interest on any Security of any series and remaining unclaimed for two years
after such principal, premium or interest has become due and payable shall be
paid to the Company on Company Request, or (if then held by the Company) shall
be discharged from such trust; and the Holder of such Security shall thereafter,
as an unsecured general creditor, look only to the Company for payment thereof,
and all liability of the Trustee or such Paying Agent with respect to such trust
money, and all liability of the Company as trustee thereof, shall thereupon
cease.

SECTION 1004.   Statement by Officers as to Default.

         The Company will deliver to the Trustee, within 120 days after the end
of each fiscal year of the Company ending after the date hereof, an Officers'
Certificate, stating whether or not to the best knowledge of the signers thereof
the Company is in default in the performance and observance of any of the terms,
provisions and conditions of this Indenture (without regard to any period of
grace or requirement of notice provided hereunder) and, if the Company shall be
in default, specifying all such defaults and the nature and status thereof of
which they may have knowledge.

<PAGE>   57

SECTION 1005.   Existence.

         Subject to Article Eight, the Company will do or cause to be done all
things necessary to preserve and keep in full force and effect its existence,
rights (charter and statutory) and franchises; provided, however, that the
Company shall not be required to preserve any such right or franchise if the
Board of Directors shall determine that the preservation thereof is no longer
desirable in the conduct of the business of the Company and that the loss
thereof is not disadvantageous in any material respect to the Holders.

SECTION 1006.   Payment of Taxes and Other Claims.

         The Company will pay or discharge or cause to be paid or discharged,
before the same shall become delinquent, (1) all taxes, assessments and
governmental charges levied or imposed upon the Company or any Subsidiary or
upon the income, profits or property of the Company or any Subsidiary, and (2)
all lawful claims for labor, materials and supplies which, if unpaid, might by
law become a lien upon the property of the Company or any Subsidiary; provided,
however, that the Company shall not be required to pay or discharge or cause to
be paid or discharged any such tax, assessment, charge or claim whose amount,
applicability or validity is being contested in good faith by appropriate
proceedings.

SECTION 1007.   Payment of Additional Amounts.

         Payments under the Securities will be made without deduction or
withholding for or on account of any present or future tax, duty, assessment or
governmental charge imposed upon or as a result of such payments by Switzerland
or any jurisdiction in which a branch of the Company through which any Security
is issued is located (or any political subdivision or taxing authority thereof
or therein) (a "Relevant Jurisdiction") ("Taxes"), unless required by law. To
the extent any such Taxes are so levied or imposed, the Company will, subject to
the exceptions and limitations set forth below, pay such additional amounts
("Additional Amounts") to the Holder of any Security who is not a resident of
the Relevant Jurisdiction or any political subdivision or taxing authority
thereof or therein as may be necessary in order that every net payment of the
principal of and interest on such Security and any other amounts payable on such
Security, after withholding for or on account of such Taxes imposed upon or as a
result of such payment, will not be less than the amount provided for in such
Security to be then due and payable. However, the Company will not be required
to make any payment of Additional Amounts to any such Holder if such payment can
be made without such deduction or withholding by a paying agent other than the
one required to make such a deduction or withholding. Further, the Company will
not be required to make any payment of Additional Amounts to any such Holder for
or on account of:

               (i) any such Taxes which would not have been so imposed but for
          (a) the existence of any present or former connection between such
          Holder (or between a fiduciary, settler, beneficiary, member or
          shareholder of such Holder, if such Holder is an estate, a trust, a
          partnership or a corporation) and Switzerland (or any political
          subdivision or taxing authority thereof or therein) including, without
          limitation, such Holder (or such fiduciary, settler, beneficiary,
          member or shareholder) being or having been a citizen or resident
          thereof or being or having been engaged in a trade or business or
          present therein or having, or having had, a permanent establishment
          therein or (b) the presentation by or on behalf of the

                                       50
<PAGE>   58

          Holder of any such Security payment on a date more than 15 days after
          the date on which such payment became due and payable or the date on
          which payment thereof is duly provided for, whichever occurs later;

               (ii) any estate, inheritance, gift, sales, transfer or personal
          property tax or any similar tax, duty, assessment or governmental
          charge;

               (iii) any Taxes which are payable otherwise than by withholding
          from payments on or in respect of any Security;

               (iv) any Taxes which would not have been imposed but for the
          failure to comply with certification, information or other reporting
          requirements concerning the nationality, residence or identity of the
          holder or beneficial owner of such Security, if such compliance is
          required by statute or by regulation of or on behalf of Switzerland or
          any political subdivision or taxing authority thereof or therein as a
          precondition to relief or exemption from such tax, assessment or other
          governmental charge; or

               (v) any combination of items (i) through (iv) above;

nor shall Additional Amounts be paid with respect to any payment on a Security
to a Holder who is a fiduciary or partnership or other than the sole beneficial
owner of such payment to the extent such payment would be required to be
included in the income, for tax purposes, of a beneficiary or settlor with
respect to such fiduciary or a member of such partnership or a beneficial owner
who would not have been entitled to the Additional Amounts had such beneficiary,
settlor, member or beneficial owner been the Holder of the Security.

         The provisions of this Section 1007 shall also apply to any Taxes
imposed by any jurisdiction in which a Person into which the Company has merged
or to which the Company has conveyed, transferred or leased its property is
located.

         For purposes of this Section 1007, any references to principal of
and/or interest on Securities shall be deemed to include a reference to any
relevant premium and/or Additional Amounts payable in respect of such
Securities.

SECTION 1008.   Waiver of Certain Covenants.

         Except as otherwise specified as contemplated by Section 301 for
Securities of such series, the Company may, with respect to the Securities of
any series, omit in any particular instance to comply with any term, provision
or condition set forth in any covenant provided pursuant to Section 301(18),
901(2) or 901(7) for the benefit of the Holders of such series [or in Article
Eight] if before the time for such compliance the Holders of at least a majority
in principal amount of the Outstanding Securities of such series shall, by Act
of such Holders, either waive such compliance in such instance or generally
waive compliance with such term, provision or condition, but no such waiver
shall extend to or affect such term, provision or condition except to the extent
so expressly waived, and, until such waiver shall become effective, the
obligations of the Company and the duties of the Trustee in respect of any such
term, provision or condition shall remain in full force and effect.

                            REDEMPTION OF SECURITIES

SECTION 1101.   Applicability of Article.

         Securities of any series which are redeemable before their Stated
Maturity shall be redeemable in accordance with their terms and (except as
otherwise specified as contemplated by Section 301 for such Securities) in
accordance with this Article.

SECTION 1102.   Election to Redeem; Notice to Trustee.

         The election of the Company to redeem any Securities shall be evidenced
by a Board Resolution or in another manner specified as contemplated by Section
301 for such Securities. In case of any redemption at the election of the
Company of less than all the Securities of any series (including any such
redemption affecting only a single Security), the Company shall, at least 60
days prior to the Redemption Date fixed by the Company (unless a shorter notice
shall be satisfactory to the Trustee), notify the Trustee of such Redemption
Date, of the principal amount of Securities of such series to be redeemed and,
if applicable, of the tenor of the Securities to be redeemed. In the case of any
redemption of Securities prior to the expiration of any restriction on such
redemption provided in the terms of such Securities or elsewhere in this
Indenture, the Company shall furnish the Trustee with an Officers' Certificate
evidencing compliance with such restriction.

SECTION 1103.   Selection by Trustee of Securities to Be Redeemed.

         If less than all the Securities of any series are to be redeemed
(unless all the Securities of such series and of a specified tenor are to be
redeemed or unless such redemption affects only a single Security), the
particular Securities to be redeemed shall be selected not more than 60 days
prior to the Redemption Date by the Trustee, from the Outstanding Securities of
such series not previously called for redemption, by such method as the Trustee
shall deem fair and appropriate and which may provide for the selection for
redemption of a portion of the principal amount of any Security of such series,
provided that the unredeemed portion of the principal amount of any Security
shall be in an authorized denomination (which shall not be less than the minimum
authorized denomination) for such Security. If less than all the Securities of
such series and of a specified tenor are to be redeemed (unless such redemption
affects only a single Security), the particular Securities to be redeemed shall
be selected not more than 60 days prior to the Redemption Date by the Trustee,
from the Outstanding Securities of such series and specified tenor not
previously called for redemption in accordance with the preceding sentence.

         If any Security selected for partial redemption is converted at the
Holder's option in part before termination of the conversion right with respect
to the portion of the Security so selected, the converted portion of such
Security shall be deemed (so far as may be) to be the portion selected for
redemption. Securities which have been converted at the Holder's option during a
selection of Securities to be redeemed shall be treated by the Trustee as
Outstanding for the purpose of such selection.

                                       52
<PAGE>   60

         The Trustee shall promptly notify the Company in writing of the
Securities selected for redemption as aforesaid and, in case of any Securities
selected for partial redemption as aforesaid, the principal amount thereof to be
redeemed.

         The provisions of the two preceding paragraphs shall not apply with
respect to any redemption affecting only a single Security, whether such
Security is to be redeemed in whole or in part. In the case of any such
redemption in part, the unredeemed portion of the principal amount of the
Security shall be in an authorized denomination (which shall not be less than
the minimum authorized denomination) for such Security.

         For all purposes of this Indenture, unless the context otherwise
requires, all provisions relating to the redemption of Securities shall relate,
in the case of any Securities redeemed or to be redeemed only in part, to the
portion of the principal amount of such Securities which has been or is to be
redeemed.

SECTION 1104.   Notice of Redemption.

         Notice of redemption shall be given by first-class mail, postage
prepaid, mailed not less than 10 nor more than 60 days prior to the Redemption
Date, to each Holder of Securities to be redeemed, at his address appearing in
the Security Register.

         All notices of redemption shall state:

          (1) the Redemption Date,

          (2) the Redemption Price,

          (3) if less than all the Outstanding Securities of any series
     consisting of more than a single Security are to be redeemed, the
     identification (and, in the case of partial redemption of any such
     Securities, the principal amounts) of the particular Securities to be
     redeemed and, if less than all the Outstanding Securities of any series
     consisting of a single Security are to be redeemed, the principal amount of
     the particular Security to be redeemed,

          (4) that on the Redemption Date the Redemption Price will become due
     and payable upon each such Security to be redeemed and, if applicable, that
     interest thereon will cease to accrue on and after said date,

          (5) the place or places where each such Security is to be surrendered
     for payment of the Redemption Price,

          (6) for any Securities that by their terms may be converted at the
     Holder's option, the terms of conversion, the date on which the right to
     convert the Security to be redeemed will terminate and the place or places
     where such Securities may be surrendered for conversion,

          (7) the CUSIP number or numbers, if any, with respect to such
     Securities, and

          (8) that the redemption is for a sinking fund, if such is the case.

                                       53
<PAGE>   61

         Notice of redemption of Securities to be redeemed at the election of
the Company shall be given by the Company or, at the Company's request, by the
Trustee in the name and at the expense of the Company and shall be irrevocable.

SECTION 1105.   Deposit of Redemption Price.

         Prior to any Redemption Date, the Company shall deposit with the
Trustee or with a Paying Agent (or, if the Company is acting as its own Paying
Agent, segregate and hold in trust as provided in Section 1003) an amount of
money sufficient to pay the Redemption Price of, and (except if the Redemption
Date shall be an Interest Payment Date) accrued interest on, all the Securities
which are to be redeemed on that date, other than any Securities called for
redemption on that date which have been converted at the Holder's option prior
to the date of such deposit.

         If any Security called for redemption is converted, any money deposited
with the Trustee or with any Paying Agent or so segregated and held in trust for
the redemption of such Security shall (subject to any right of the Holder of
such Security or any Predecessor Security to receive interest as provided in the
last paragraph of Section 307 or in the terms of such Security) be paid to the
Company upon Company Request or, if then held by the Company, shall be
discharged from such trust.

SECTION 1106.   Securities Payable on Redemption Date.

         Notice of redemption having been given as aforesaid, the Securities so
to be redeemed shall, on the Redemption Date, become due and payable at the
Redemption Price therein specified, and from and after such date (unless the
Company shall default in the payment of the Redemption Price and accrued
interest) such Securities shall cease to bear interest. Upon surrender of any
such Security for redemption in accordance with said notice, such Security shall
be paid by the Company at the Redemption Price, together with accrued interest
to the Redemption Date; provided, however, that, unless otherwise specified as
contemplated by Section 301, installments of interest whose Stated Maturity is
on or prior to the Redemption Date will be payable to the Holders of such
Securities, or one or more Predecessor Securities, registered as such at the
close of business on the relevant Record Dates according to their terms and the
provisions of Section 307.

         If any Security called for redemption shall not be so paid upon
surrender thereof for redemption, the principal and any premium shall, until
paid, bear interest from the Redemption Date at the rate prescribed therefor in
the Security.

SECTION 1107.   Securities Redeemed in Part.

         Any Security which is to be redeemed only in part shall be surrendered
at a Place of Payment therefor (with, if the Company or the Trustee so requires,
due endorsement by, or a written instrument of transfer in form satisfactory to
the Company and the Trustee duly executed by, the Holder thereof or his attorney
duly authorized in writing), and the Company shall execute, and the Trustee
shall authenticate and deliver to the Holder of such Security without service
charge, a new Security or Securities of the same series and of like tenor, of
any authorized denomination as requested by such Holder, in aggregate principal
amount equal to and in exchange for the unredeemed portion of the principal of
the Security so surrendered.

<PAGE>   62

SECTION 1108.   Optional Redemption for Tax Reasons.

         Unless otherwise specified for a particular series of Securities, the
Company may, on giving not more than 60 nor less than 10 days' notice to the
Trustee (which notice shall be irrevocable), redeem the Securities of any Series
then outstanding at a redemption price equal to the principal amount of the
Securities (or if the Securities are original issue discount securities, such
amount as determined pursuant to the formula set forth in the applicable
indenture supplement) plus any related Additional Amounts (as defined in Section
1007 herein), in each case with respect to the Securities being redeemed, in the
event that: (a) the Company determines that, as a result of any change in or
amendment to the laws (or any regulations or rulings promulgated thereunder) of
a Relevant Jurisdiction (as defined in Section 1007) affecting taxation, or any
change in official position regarding the application or interpretation of such
laws, regulations or rulings, the Company has or will become obligated to pay
Additional Amounts with respect to the Securities of such Series; or (b) a
person located outside of a Relevant Jurisdiction into which the Company is
merged or to which it has conveyed, transferred or leased its property is
required to pay Additional Amounts. Nothing in subsection (b) of this Section
1108 requires the Company to use reasonable measures to avoid the obligation of
pay Additional Amounts in the event of such merger, conveyance, transfer or
lease. The Trustee will notify the Holders at least 20 days prior to the date
fixed for any such redemption. Prior to the giving of any notice of redemption
for tax reasons as described in this paragraph, the Company shall deliver to the
Trustee (i) an Officers' Certificate stating that the Company is entitled to
effect such redemption and setting forth a statement of facts showing that the
conditions precedent to the right of the Company to so redeem have occurred and
(ii) an opinion of counsel to such effect based on such statement of facts;
provided that no such notice of redemption shall be given earlier than 60 days
prior to the earliest date on which the Company would be obligated to pay such
Additional Amounts if a payment in respect of the Securities were then due.

                                 ARTICLE TWELVE

                                  SINKING FUNDS

SECTION 1201.   Applicability of Article.

         The provisions of this Article shall be applicable to any sinking fund
for the retirement of Securities of any series except as otherwise specified as
contemplated by Section 301 for such Securities.

         The minimum amount of any sinking fund payment provided for by the
terms of any Securities is herein referred to as a "mandatory sinking fund
payment", and any payment in excess of such minimum amount provided for by the
terms of such Securities is herein referred to as an "optional sinking fund
payment". If provided for by the terms of any Securities, the cash amount of any
sinking fund payment may be subject to reduction as provided in Section 1202.
Each sinking fund payment shall be applied to the redemption of Securities as
provided for by the terms of such Securities.

                                       55
<PAGE>   63

SECTION 1202.   Satisfaction of Sinking Fund Payments with Securities.

         The Company (1) may deliver Outstanding Securities of a series (other
than any previously called for redemption) and (2) may apply as a credit
Securities of a series which have been redeemed either at the election of the
Company pursuant to the terms of such Securities or through the application of
permitted optional sinking fund payments pursuant to the terms of such
Securities, in each case in satisfaction of all or any part of any sinking fund
payment with respect to any Securities of such series required to be made
pursuant to the terms of such Securities as and to the extent provided for by
the terms of such Securities; provided that the Securities to be so credited
have not been previously so credited. The Securities to be so credited shall be
received and credited for such purpose by the Trustee at the Redemption Price,
as specified in the Securities so to be redeemed, for redemption through
operation of the sinking fund and the amount of such sinking fund payment shall
be reduced accordingly.

SECTION 1203.   Redemption of Securities for Sinking Fund.

         Not less than 60 days prior to each sinking fund payment date for any
Securities, the Company will deliver to the Trustee an Officers' Certificate
specifying the amount of the next ensuing sinking fund payment for such
Securities pursuant to the terms of such Securities, the portion thereof, if
any, which is to be satisfied by payment of cash and the portion thereof, if
any, which is to be satisfied by delivering and crediting Securities pursuant to
Section 1202 and will also deliver to the Trustee any Securities to be so
delivered. Not less than 45 days prior to each such sinking fund payment date,
the Trustee shall select the Securities to be redeemed upon such sinking fund
payment date in the manner specified in Section 1103 and cause notice of the
redemption thereof to be given in the name of and at the expense of the Company
in the manner provided in Section 1104. Such notice having been duly given, the
redemption of such Securities shall be made upon the terms and in the manner
stated in Sections 1106 and 1107.

                                ARTICLE THIRTEEN

                       DEFEASANCE AND COVENANT DEFEASANCE

SECTION 1301.   Company's Option to Effect Defeasance or Covenant Defeasance.

         The Company may elect, at its option at any time, to have Section 1302
or Section 1303 applied to any Securities or any series of Securities, as the
case may be, designated pursuant to Section 301 as being defeasible pursuant to
such Section 1302 or 1303, in accordance with any applicable requirements
provided pursuant to Section 301 and upon compliance with the conditions set
forth below in this Article. Any such election shall be evidenced by a Board
Resolution or in another manner specified as contemplated by Section 301 for
such Securities.

SECTION 1302.   Defeasance and Discharge.

         Upon the Company's exercise of its option (if any) to have this Section
applied to any Securities or any series of Securities, as the case may be, the
Company shall be deemed to have been discharged from its obligations with
respect to such Securities as provided in this Section on and after the date the
conditions set forth in Section 1304 are satisfied (hereinafter called
"Defeasance"). For this purpose, such Defeasance means that the Company shall be
deemed to

                                       56
<PAGE>   64

have paid and discharged the entire indebtedness represented by such Securities
and to have satisfied all its other obligations under such Securities and this
Indenture insofar as such Securities are concerned (and the Trustee, at the
expense of the Company, shall execute proper instruments acknowledging the
same), subject to the following which shall survive until otherwise terminated
or discharged hereunder: (1) the rights of Holders of such Securities to
receive, solely from the trust fund described in Section 1304 and as more fully
set forth in such Section, payments in respect of the principal of and any
premium and interest on such Securities when payments are due, (2) the Company's
obligations with respect to such Securities under Sections 304, 305, 306, 1002
and 1003, (3) the rights, powers, trusts, duties and immunities of the Trustee
hereunder and (4) this Article. Subject to compliance with this Article, the
Company may exercise its option (if any) to have this Section applied to any
Securities notwithstanding the prior exercise of its option (if any) to have
Section 1303 applied to such Securities.

SECTION 1303.   Covenant Defeasance.

         Upon the Company's exercise of its option (if any) to have this Section
applied to any Securities or any series of Securities, as the case may be, (1)
the Company shall be released from its obligations under Section 801(3), Section
1006 and any covenants provided pursuant to Section 301(18), 901(2) or 901(7)
for the benefit of the Holders of such Securities, and (2) the occurrence of any
event specified in Sections 501(4) (with respect to any of Section 801(3),
Section 1006 and any such covenants provided pursuant to Section 301(18), 901(2)
or 901(7)), and 501(7) shall be deemed not to be or result in an Event of
Default, in each case with respect to such Securities as provided in this
Section on and after the date the conditions set forth in Section 1304 are
satisfied (hereinafter called "Covenant Defeasance"). For this purpose, such
Covenant Defeasance means that, with respect to such Securities, the Company may
omit to comply with and shall have no liability in respect of any term,
condition or limitation set forth in any such specified Section (to the extent
so specified in the case of Section 501(4)), whether directly or indirectly by
reason of any reference elsewhere herein to any such Section or by reason of any
reference in any such Section to any other provision herein or in any other
document, but the remainder of this Indenture and such Securities shall be
unaffected thereby.

SECTION 1304.   Conditions to Defeasance or Covenant Defeasance.

         The following shall be the conditions to the application of Section
1302 or Section 1303 to any Securities or any series of Securities, as the case
may be:

          (1) The Company shall irrevocably have deposited or caused to be
     deposited with the Trustee (or another trustee which satisfies the
     requirements contemplated by Section 609 and agrees to comply with the
     provisions of this Article applicable to it) as trust funds in trust for
     the purpose of making the following payments, specifically pledged as
     security for, and dedicated solely to, the benefits of the Holders of such
     Securities, (A) money in an amount, or (B) U.S. Government Obligations
     which through the scheduled payment of principal and interest in respect
     thereof in accordance with their terms will provide, not later than one day
     before the due date of any payment, money in an amount, or (C) a
     combination thereof, in each case sufficient, in the opinion of a
     nationally recognized firm of independent public accountants expressed in a
     written certification thereof delivered to the Trustee, to pay and
     discharge, and which shall be applied by the Trustee (or any such other
     qualifying trustee) to pay and discharge, the principal of and any premium
     and interest on such Securities on the respective Stated Maturities, in
     accordance with the terms of this Indenture and such

                                       57
<PAGE>   65

     Securities. As used herein, "U.S. Government Obligation" means (x) any
     security which is (i) a direct obligation of the United States of America
     for the payment of which the full faith and credit of the United States of
     America is pledged or (ii) an obligation of a Person controlled or
     supervised by and acting as an agency or instrumentality of the United
     States of America the payment of which is unconditionally guaranteed as a
     full faith and credit obligation by the United States of America, which, in
     either case (i) or (ii), is not callable or redeemable at the option of the
     issuer thereof, and (y) any depositary receipt issued by a bank (as defined
     in Section 3(a)(2) of the Securities Act) as custodian with respect to any
     U.S. Government Obligation which is specified in Clause (x) above and held
     by such bank for the account of the holder of such depositary receipt, or
     with respect to any specific payment of principal of or interest on any
     U.S. Government Obligation which is so specified and held, provided that
     (except as required by law) such custodian is not authorized to make any
     deduction from the amount payable to the holder of such depositary receipt
     from any amount received by the custodian in respect of the U.S. Government
     Obligation or the specific payment of principal or interest evidenced by
     such depositary receipt.

          (2) In the event of an election to have Section 1302 apply to any
     Securities or any series of Securities, as the case may be, the Company
     shall have delivered to the Trustee an Opinion of Counsel stating that (A)
     the Company has received from, or there has been published by, the Internal
     Revenue Service a ruling or (B) since the date of this instrument, there
     has been a change in the applicable Federal income tax law, in either case
     (A) or (B) to the effect that, and based thereon such opinion shall confirm
     that, the Holders of such Securities will not recognize gain or loss for
     Federal income tax purposes as a result of the deposit, Defeasance and
     discharge to be effected with respect to such Securities and will be
     subject to Federal income tax on the same amount, in the same manner and at
     the same times as would be the case if such deposit, Defeasance and
     discharge were not to occur.

          (3) In the event of an election to have Section 1303 apply to any
     Securities or any series of Securities, as the case may be, the Company
     shall have delivered to the Trustee an Opinion of Counsel to the effect
     that the Holders of such Securities will not recognize gain or loss for
     Federal income tax purposes as a result of the deposit and Covenant
     Defeasance to be effected with respect to such Securities and will be
     subject to Federal income tax on the same amount, in the same manner and at
     the same times as would be the case if such deposit and Covenant Defeasance
     were not to occur.

          (4) The Company shall have delivered to the Trustee an Officers'
     Certificate to the effect that neither such Securities nor any other
     Securities of the same series, if then listed on any securities exchange,
     will be delisted as a result of such deposit.

          (5) No event which is, or after notice or lapse of time or both would
     become, an Event of Default with respect to such Securities or any other
     Securities shall have occurred and be continuing at the time of such
     deposit or, with regard to any such event specified in Sections 501(5) and
     (6), at any time on or prior to the 90th day after the date of such deposit
     (it being understood that this condition shall not be deemed satisfied
     until after such 90th day).

          (6) Such Defeasance or Covenant Defeasance shall not cause the Trustee
     to have a conflicting interest within the meaning of the Trust Indenture
     Act (assuming all Securities are in default within the meaning of such
     Act).

                                       58
<PAGE>   66

          (7) Such Defeasance or Covenant Defeasance shall not result in a
     breach or violation of, or constitute a default under, any other agreement
     or instrument to which the Company is a party or by which it is bound.

          (8) Such Defeasance or Covenant Defeasance shall not result in the
     trust arising from such deposit constituting an investment company within
     the meaning of the Investment Company Act unless such trust shall be
     registered under such Act or exempt from registration thereunder.

          (9) The Company shall have delivered to the Trustee an Officers'
     Certificate and an Opinion of Counsel, each stating that all conditions
     precedent with respect to such Defeasance or Covenant Defeasance have been
     complied with.

SECTION 1305.   Deposited Money and U.S. Government Obligations to Be Held in
                Trust; Miscellaneous Provisions.

         Subject to the provisions of the last paragraph of Section 1003, all
money and U.S. Government Obligations (including the proceeds thereof) deposited
with the Trustee or other qualifying trustee (solely for purposes of this
Section and Section 1306, the Trustee and any such other trustee are referred to
collectively as the "Trustee") pursuant to Section 1304 in respect of any
Securities shall be held in trust and applied by the Trustee, in accordance with
the provisions of such Securities and this Indenture, to the payment, either
directly or through any such Paying Agent (including the Company acting as its
own Paying Agent) as the Trustee may determine, to the Holders of such
Securities, of all sums due and to become due thereon in respect of principal
and any premium and interest, but money so held in trust need not be segregated
from other funds except to the extent required by law.

         The Company shall pay and indemnify the Trustee against any tax, fee or
other charge imposed on or assessed against the U.S. Government Obligations
deposited pursuant to Section 1304 or the principal and interest received in
respect thereof other than any such tax, fee or other charge which by law is for
the account of the Holders of Outstanding Securities.

         Anything in this Article to the contrary notwithstanding, the Trustee
shall deliver or pay to the Company from time to time upon Company Request any
money or U.S. Government Obligations held by it as provided in Section 1304 with
respect to any Securities which, in the opinion of a nationally recognized firm
of independent public accountants expressed in a written certification thereof
delivered to the Trustee, are in excess of the amount thereof which would then
be required to be deposited to effect the Defeasance or Covenant Defeasance, as
the case may be, with respect to such Securities.

SECTION 1306.   Reinstatement.

         If the Trustee or the Paying Agent is unable to apply any money in
accordance with this Article with respect to any Securities by reason of any
order or judgment of any court or governmental authority enjoining, restraining
or otherwise prohibiting such application, then the obligations under this
Indenture and such Securities from which the Company has been discharged or
released pursuant to Section 1302 or 1303 shall be revived and reinstated as
though no deposit had occurred pursuant to this Article with respect to such
Securities, until such time as the Trustee or Paying Agent is permitted to apply
all money held in trust pursuant to Section 1305

                                       59
<PAGE>   67

with respect to such Securities in accordance with this Article; provided,
however, that if the Company makes any payment of principal of or any premium or
interest on any such Security following such reinstatement of its obligations,
the Company shall be subrogated to the rights (if any) of the Holders of such
Securities to receive such payment from the money so held in trust.

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

                                       -2-
<PAGE>   4

            (a)   Organization and Qualification.  The Company is a
corporation duly incorporated, validly existing and in good standing under
the laws of the State of New Jersey, with the requisite corporate power and
authority to own and use its properties and assets and to carry on its
business as currently conducted.  The Company has no subsidiaries other than
as set forth in Schedule 2.1(a) (collectively, the "Subsidiaries").  Each of
the Subsidiaries is an entity, duly incorporated or otherwise organized,
validly existing and in good standing under the laws of the jurisdiction of
its incorporation or organization (as applicable), with the requisite power
and authority to own and use its properties and assets and to carry on its
business as currently conducted.  Each of the Company and the Subsidiaries is
duly qualified to do business and is in good standing as a foreign
corporation or other entity in each jurisdiction in which the nature of the
business conducted or property owned by it makes such qualification
necessary, except where the failure to be so qualified or in good standing,
as the case may be, could not, individually or in the aggregate, (x)
adversely affect the legality, validity or enforceability of the Securities
(as defined below) or any of this Agreement, the Registration Rights
Agreement, the Certificate of Designation, the Transfer Agent Instructions or
the Warrants (collectively, the "Transaction Documents"), (y) have or result
in a material adverse effect on the results of operations, assets, prospects,
or condition (financial or otherwise) of the Company and the Subsidiaries,
taken as a whole, or (z) adversely impair the Company's ability to perform
fully on a timely basis its obligations under any of the Transaction
Documents (any of (x), (y) or (z), a "Material Adverse Effect").

            (b)   Authorization; Enforcement.  The Company has the requisite
corporate power and authority to enter into and to consummate the
transactions contemplated by each of the Transaction Documents and otherwise
to carry out its obligations thereunder.  The execution and delivery of each
of the Transaction Documents by the Company and the consummation by it of the
transactions contemplated thereby have been duly authorized by all necessary
action on the part of the Company and no further action is required by the
Company.  Each of the Transaction Documents has been duly executed by the
Company and, when delivered (or filed, as the case may be) in accordance with
the terms hereof, will constitute the valid and binding obligation of the
Company enforceable against the Company in accordance with its terms.
Neither the Company nor any Subsidiary is in violation of any of the
provisions of its respective certificate or articles of incorporation,
by-laws or other organizational or charter documents.

            (c)   Capitalization.  The number of authorized, issued and
outstanding capital stock of the Company is set forth in Schedule 2.1(c).
Except as disclosed in Schedule 2.1(c), the Company owns all of the capital
stock of each Subsidiary.  No shares of Common Stock are entitled to
preemptive or similar rights, nor is any holder of the securities of the
Company or any Subsidiary entitled to preemptive or similar rights arising
out of any agreement or understanding with the Company or any Subsidiary by
virtue of any of the Transaction Documents.  Except as a result of the
purchase and sale of the Shares and the Warrants and except as disclosed in
Schedule 2.1(c), there are no outstanding options, warrants, script rights to
subscribe to, calls or commitments of any character whatsoever relating to,
or securities, rights or obligations convertible into or exchangeable for, or
giving any Person any right to subscribe for or acquire, any shares of Common
Stock, or contracts, commitments, understandings, or arrangements by which
the Company or any Subsidiary is or may become bound to issue additional
shares of Common Stock, or securities or rights convertible or exchangeable
into shares of Common

                                       -3-
<PAGE>   5

Stock. The issue and sale of the Shares, Warrants or Underlying Shares (as
hereinafter defined) will not obligate the Company to issue shares of Common
Stock or other securities to any Person other than the Purchaser and will not
result in a right of any holder of Company's securities to adjust the exercise
or conversion or reset price under such securities.

            (d)   Issuance of the Shares and the Warrants.  The Shares and
the Warrants are duly authorized and, when issued and paid for in accordance
with the terms hereof, will be duly and validly issued, fully paid and
nonassessable, free and clear of all liens, encumbrances and rights of first
refusal of any kind (collectively, "Liens") other than liens created by the
holders thereof.  The Company has on the date hereof and will, at all times
while the Shares and the Warrants are outstanding, maintain an adequate
reserve of duly authorized shares of Common Stock, reserved for issuance to
the holders of the Shares and the Warrants, to enable it to perform its
conversion, exercise and other obligations under this Agreement, the
Certificate of Designation and the Warrants.  Such number of reserved and
available shares of Common Stock is not less than the sum of (i) the number
of shares of Common Stock issuable upon conversion in full of the outstanding
Shares, assuming for such purposes that such Shares are outstanding for five
years, and that all accrued dividends are added to the Stated Value (as
defined in the Certificate of Designation), and (ii) the number of shares of
Common Stock issuable upon exercise in full of the Warrants, assuming for
such purposes that (1) the Closing Warrants are exercised in full on the
Closing Date at an exercise price equal to 50% of the  closing sales price of
the Common Stock (as reported by Bloomberg L.P. or the successor to its
function of reporting share prices) on the Closing Date, the Filing Date or
the Trading Day preceding the date the Company files an acceleration request
with the Commission relating to the Registration Statement, whichever is
lowest, and (2) the Redemption Warrants fully vest and are exercisable in
full on the Closing Date.(such number of shares of Common Stock as
contemplated in clauses (i)-(ii), the "Initial Minimum").  All such
authorized shares of Common Stock shall be duly reserved for issuance to the
holders of the Shares and the Warrants.  The shares of Common Stock issuable
upon conversion of the Shares and upon exercise of the Warrants are
collectively referred to herein as the "Underlying Shares."  The Shares, the
Warrants and the Underlying Shares are collectively referred to herein as,
the "Securities."  When issued in accordance with the Certificate of
Designation and the Warrants, the Underlying Shares will be duly authorized,
validly issued, fully paid and nonassessable, free and clear of all Liens
other than liens created by the holders thereof.

            (e)   No Conflicts.  The execution, delivery and performance of
the Transaction Documents by the Company and the consummation by the Company
of the transactions contemplated thereby do not and will not (i) conflict
with or violate any provision of the Company's or any Subsidiary's
certificate or articles of incorporation, bylaws or other charter documents
(each as amended through the date hereof), or (ii) subject to obtaining the
Required Approvals (as defined below), conflict with, or constitute a default
(or an event which with notice or lapse of time or both would become a
default) under, or give to others any rights of termination, amendment,
acceleration or cancellation (with or without notice, lapse of time or both)
of, any agreement, credit facility, debt or other instrument or other
understanding to which the Company or any Subsidiary is a party or by which
any property or asset of the Company or any Subsidiary is bound or affected,
or (iii) result in a violation of any law, rule, regulation, order, judgment,
injunction, decree or other restriction of any court or governmental
authority to

                                       -4-
<PAGE>   6

which the Company or a Subsidiary is subject (including federal and state
securities laws and regulations), or by which any property or asset of the
Company or a Subsidiary is bound or affected; except in the case of each of
clauses (ii) and (iii), as could not, individually or in the aggregate, have or
result in a Material Adverse Effect. The business of the Company is not being
conducted in violation of any law, ordinance or regulation of any governmental
authority, except for violations which, individually or in the aggregate, could
not have or result in a Material Adverse Effect.

            (f)   Filings, Consents and Approvals.  Neither the Company nor
any Subsidiary is required to obtain any consent, waiver, authorization or
order of, give any notice to, or make any filing or registration with, any
court or other federal, state, local or other governmental authority or other
Person in connection with the execution, delivery and performance by the
Company of the Transaction Documents, other than (i) the filing of the
Certificate of Designation with the Secretary of State of New Jersey, (ii)
the filings required pursuant to Section 3.9, (iii) the filing with the
Securities and Exchange Commission (the "Commission") of a registration
statement meeting the requirements set forth in the Registration Rights
Agreement and covering the resale of the Underlying Shares by the Purchasers
(the "Underlying Shares Registration Statement"), (iv) the application(s) to
the Nasdaq National Market ("NASDAQ") for the listing of the Underlying
Shares for trading on the NASDAQ (and with any other national securities
exchange  or market on which the Common Stock is then listed) in the time and
manner required thereby, (v) applicable Blue Sky filings, and (vi) in all
other cases where the failure to obtain such consent, waiver, authorization
or order, or to give such notice or make such filing or registration could
not have or result in, individually or in the aggregate, a Material Adverse
Effect (collectively, the "Required Approvals").

            (g)   Litigation; Proceedings.   There is no action, suit,
inquiry, notice of violation, proceeding or investigation pending or, to the
knowledge of the Company, threatened against or affecting the Company or any
of its Subsidiaries or any of their respective properties before or by any
court, arbitrator, governmental or administrative agency or regulatory
authority (federal, state, county, local or foreign) (collectively, an
"Action") which (i) adversely affects or challenges the legality, validity or
enforceability of any of the Transaction Documents or the Securities or (ii)
could, if there were an unfavorable decision, individually or in the
aggregate, have or result in a Material Adverse Effect.  Except as described
in the SEC Documents, (i) neither the Company nor any Subsidiary, nor any
director or officer thereof, is or has been the subject of any Action
involving (A) a claim of violation of or liability under federal or state
securities laws or (B) a claim of breach of fiduciary duty; (ii) the Company
does not have pending before the Commission any request for confidential
treatment of information and the Company has no knowledge of any expected
such request that would be made prior to the Effectiveness Date (as defined
in the Registration Rights Agreement); and (iii) there has not been, and to
the best of the Company's knowledge there is not pending or contemplated, any
investigation by the Commission involving the Company or any current or
former director or officer of the Company.

            (h)   No Default or Violation.  Neither the Company nor any
Subsidiary (i) is in default under or in violation of (and no event has
occurred which has not been waived which, with notice or lapse of time or
both, would result in a default by the Company or any Subsidiary under), nor
has the Company or any Subsidiary received notice of a claim that it is in
default

                                       -5-
<PAGE>   7

under or that it is in violation of, any indenture, loan or credit
agreement or any other agreement or instrument to which it is a party or by
which it or any of its properties is bound, (ii) is in violation of any order
of any court, arbitrator or governmental body, or (iii) is in violation of
any statute, rule or regulation of any governmental authority, in each case
of clauses (i), (ii) or (iii) above, except as could not individually or in
the aggregate, have or result in a Material Adverse Effect.

            (i)   Private Offering.  Assuming the accuracy of the
representations and warranties of the Purchasers set forth in Sections
2.2(b)-(g), the offer, issuance and sale of the Securities to the Purchasers
as contemplated hereby are exempt from the registration requirements of the
Securities Act.  Neither the Company nor any Person acting on its behalf has
taken or is, to the knowledge of the Company, contemplating taking any action
which could subject the offering, issuance or sale of the Securities to the
registration requirements of the Securities Act including soliciting any
offer to buy or sell the Securities by means of any form of general
solicitation or advertising.

            (j)   SEC Documents; Financial Statements.  The Company has filed
all reports required to be filed by it under the Securities Exchange Act of
1934, as amended (the "Exchange Act"), including pursuant to Section 13(a) or
15(d) thereof, for the two years preceding the date hereof (or such shorter
period as the Company was required by law to file such material) (the
foregoing materials being collectively referred to herein as the "SEC
Documents" and, together with the Schedules to this Agreement, the
"Disclosure Materials") on a timely basis or has received a valid extension
of such time of filing and has filed any such SEC Documents prior to the
expiration of any such extension.  As of their respective dates, the SEC
Documents complied in all material respects with the requirements of the
Securities Act and the Exchange Act and the rules and regulations of the
Commission promulgated thereunder, and none of the SEC Documents, when filed,
contained any untrue statement of a material fact or omitted to state a
material fact required to be stated therein or necessary in order to make the
statements therein, in light of the circumstances under which they were made,
not misleading.  All material agreements to which the Company is a party or
to which the property or assets of the Company are subject have been filed as
exhibits to the SEC Documents as required under the Exchange Act.  The
financial statements of the Company included in the SEC Documents comply in
all material respects with applicable accounting requirements and the rules
and regulations of the Commission with respect thereto as in effect at the
time of filing.  Such financial statements have been prepared in accordance
with generally accepted accounting principles applied on a consistent basis
during the periods involved ("GAAP"), except as may be otherwise specified in
such financial statements or the notes thereto, and fairly present in all
material respects the financial position of the Company and its consolidated
subsidiaries as of and for the dates thereof and the results of operations
and cash flows for the periods then ended, subject, in the case of unaudited
statements, to normal, immaterial, year-end audit adjustments.  Since June

has been no event, occurrence or development that has or that could result in
a Material Adverse Effect, (b) the Company has not incurred any liabilities
(contingent or otherwise) other than (x) liabilities incurred in the ordinary
course of business consistent with past practice and (y) liabilities not
required to be reflected in the Company's financial statements pursuant to
GAAP or otherwise required to be disclosed in filings made with the
Commission, (c) the Company has not altered its method of

                                       -6-
<PAGE>   8

accounting or the identity of its auditors and (d) the Company has not declared
or made any payment or distribution of cash or other property to its
stockholders or officers or directors (other than in compliance with existing
Company stock option plans) with respect to its capital stock, or purchased,
redeemed (or made any agreements to purchase or redeem) any shares of its
capital stock.

            (k)   Investment Company.  The Company is not, and is not an
Affiliate (as defined in Rule 405 under the Securities Act) of, an
"investment company" within the meaning of the Investment Company Act of
1940, as amended.

            (l)   Certain Fees.  Except for certain fees payable to Oswestry
Research Co. by the Company, no fees or commissions will be payable by the
Company to any broker, financial advisor or consultant, finder, placement
agent, investment banker, bank or other Person with respect to the
transactions contemplated by this Agreement.  The Purchasers shall have no
obligation with respect to any fees or with respect to any claims made by or
on behalf of other Persons for fees of a type contemplated in this Section
that may be due in connection with the transactions contemplated by this
Agreement.  The Company shall indemnify and hold harmless the Purchasers,
their employees, officers, directors, agents, and partners, and their
respective Affiliates, from and against all claims, losses, damages, costs
(including the costs of preparation and attorney's fees) and expenses
suffered in respect of any such claimed or existing fees, as such fees and
expenses are incurred.

            (m)   Form S-1 Eligibility.  The Company is eligible to register
securities for resale with the Commission under Form S-1 promulgated under
the Securities Act.

            (n)   Seniority.  No class of equity securities of the Company is
senior to the Shares in right of payment, whether upon liquidation or
dissolution, or otherwise.

            (o)   Listing and Maintenance Requirements.  Except as set forth
in the SEC Documents, the Company has not, in the two years preceding the
date hereof received notice (written or oral) from the NASDAQ, any stock
exchange, market or trading facility on which the Common Stock is or has been
listed (or on which it has been quoted) to the effect that the Company is not
in compliance with the listing or maintenance requirements of such exchange,
market or trading facility.  The Company is, and has no reason to believe
that it will not in the foreseeable future continue to be, in compliance with
all such listing and maintenance requirements.

            (p)   Patents and Trademarks.  The Company and its Subsidiaries
have, or have rights to use, all patents, patent applications, trademarks,
trademark applications, service marks, trade names, copyrights, licenses and
rights which are necessary or material for use in connection with their
respective businesses as described in the SEC Documents  and which the
failure to so have would have a Material Adverse Effect (collectively, the
"Intellectual Property Rights").  Neither the Company nor any Subsidiary has
received a written notice that the Intellectual Property Rights used by the
Company or its Subsidiaries violates or infringes upon the rights of any
Person.  To the best knowledge of the Company, all such Intellectual Property
Rights are

                                       -7-
<PAGE>   9

enforceable and there is no existing infringement by another Person of any of
the Intellectual Property Rights.

            (q)   Registration Rights; Rights of Participation. Except as
disclosed in Section 6(c) of the Registration Rights Agreement, the Company
has not granted or agreed to grant to any Person any rights (including
"piggy-back" registration rights) to have any securities of the Company
registered with the Commission or any other governmental authority which have
not been satisfied. No Person, has any right of first refusal, preemptive
right, right of participation, or any similar right to participate in the
transactions contemplated by the Transaction Documents.

            (r)   Regulatory Permits.  The Company and its Subsidiaries
possess all certificates, authorizations and permits issued by the
appropriate federal, state or foreign regulatory authorities necessary to
conduct their respective businesses as described in the SEC Documents, except
where the failure to possess such permits could not, individually or in the
aggregate, have or result in a Material Adverse Effect ("Material Permits"),
and neither the Company nor any such Subsidiary has received any notice of
proceedings relating to the revocation or modification of any Material Permit.

            (s)   Title.  The Company and the Subsidiaries have good and
marketable title in fee simple to all real property owned by them which is
material to the business of the Company and its Subsidiaries and good and
marketable title in all personal property owned by them which is material to
the business of the Company and its Subsidiaries, in each case free and clear
of all Liens, except for Liens as do not materially affect the value of such
property and do not interfere with the use made and proposed to be made of
such property by the Company and its Subsidiaries.  Any real property and
facilities held under lease by the Company and its Subsidiaries are held by
them under valid, subsisting and enforceable leases of which the Company and
its Subsidiaries are in compliance and do not interfere with the use made and
proposed to be made of such property and buildings by the Company and its
Subsidiaries.

            (t)   Labor Relations.  No material labor problem exists or, to
the knowledge of the Company, is imminent with respect to any of the
employees of the Company.

            (u)   Shareholders Rights Plan. Neither the consummation of the
transactions contemplated hereby nor the issuance of the Underlying Shares
will cause the Purchasers to be deemed an "Acquiring Person" under any
existing or hereafter adopted shareholders rights plan or similar arrangement.

            (v)   Disclosure.   The Company confirms that neither it nor any
other Person acting on its behalf has provided any of the Purchasers or its
agents or counsel with any information that constitutes or might constitute
material non-public information.  The Company understands and confirms that
the Purchasers shall be relying on the foregoing representations in effecting
transactions in securities of the Company. All disclosure provided to the
Purchasers regarding the Company, its business and the transactions
contemplated hereby, including the Schedules to this Agreement, furnished by
or on behalf of the Company are true and correct in all material respects and
do not contain any untrue statement of a material fact or omit to state any

                                       -8-
<PAGE>   10

material fact necessary in order to make the statements made therein, in
light of the circumstances under which they were made, not misleading.

      2.2   Representations and Warranties of the Purchasers.  Each Purchaser
hereby for itself and for no other Purchaser represents and warrants to the
Company as follows:

            (a)   Organization; Authority.  Such Purchaser is an entity duly
organized, validly existing and in good standing under the laws of the
jurisdiction of its organization with the requisite corporate or partnership
power and authority to enter into and to consummate the transactions
contemplated by the Transaction Documents and otherwise to carry out its
obligations thereunder.  The purchase by such Purchaser of the Securities
hereunder has been duly authorized by all necessary action on the part of
such Purchaser.  Each of this Agreement and the Registration Rights Agreement
has been duly executed by such Purchaser, and when delivered by such
Purchaser in accordance with the terms hereof, will constitute the valid and
legally binding obligation of such Purchaser, enforceable against it in
accordance with its terms.

            (b)   Investment Intent.  Such Purchaser is acquiring the
Securities as principal for its own account for investment purposes only and
not with a view to or for distributing or reselling such Securities or any
part thereof, without prejudice, however, to such Purchaser's right, subject

the Warrants, at all times to sell or otherwise dispose of all or any part of
such Securities pursuant to an effective registration statement under the
Securities Act or under an exemption from such registration and in compliance
with applicable federal and state securities laws.  Nothing contained herein
shall be deemed a representation or warranty by such Purchaser to hold
Securities for any period of time.  Such Purchaser is acquiring the
Securities hereunder in the ordinary course of its business.  Such Purchaser
does not have any agreement or understanding, directly or indirectly, with
any Person to distribute the Securities.

            (c)   Purchaser Status.  At the time such Purchaser was offered
the Securities, it was, and at the date hereof it is, and at each exercise
date under its respective Warrants, it will be, an "accredited investor" as
defined in Rule 501(a) under the Securities Act.

            (d)   Experience of such Purchaser.  Such Purchaser, either alone
or together with its representatives, has such knowledge, sophistication and

            (e)   Ability of such Purchaser to Bear Risk of Investment.  Such
Purchaser is able to bear the economic risk of an investment in the
Securities and, at the present time, is able to afford a complete loss of
such investment.

            (f)   Access to Information.  Such Purchaser acknowledges that it
has reviewed the Disclosure Materials and has been afforded (i) the
opportunity to ask such questions as it has deemed necessary of, and to
receive answers from, representatives of the Company concerning the terms and
conditions of the offering of the Securities and the merits and risks of
investing in

the Securities; (ii) access to information about the Company and the Company's
financial condition, results of operations, business, properties, management and
prospects sufficient to enable it to evaluate its investment; and (iii) the
opportunity to obtain such additional information which the Company possesses or
can acquire without unreasonable effort or expense that is necessary to make an
informed investment decision with respect to the investment and to verify the
accuracy and completeness of the information contained in the Disclosure
Materials. Neither such inquiries nor any other investigation conducted by or on
behalf of such Purchaser or its representatives or counsel shall modify, amend
or affect such Purchaser's right to rely on the truth, accuracy and completeness
of the Disclosure Materials and the Company's representations and warranties
contained in the Transaction Documents.

            (g)   General Solicitation.  Such Purchaser is not purchasing the
Securities as a result of or subsequent to any advertisement, article, notice
or other communication regarding the Securities published in any newspaper,
magazine or similar media or broadcast over television or radio or presented
at any seminar or any other general solicitation or general advertisement.

            (h)   Reliance.  Such Purchaser understands and acknowledges that
(i) the Securities are being offered and sold to it without registration
under the Securities Act in a private placement that is exempt from the
registration provisions of the Securities Act and (ii) the availability of
such exemption, depends in part on, and the Company will rely upon the
accuracy and truthfulness of, the foregoing representations and such
Purchaser hereby consents to such reliance.

            The Company acknowledges and agrees that no Purchaser makes or
has made any representations or warranties with respect to the transactions
contemplated hereby other than those specifically set forth in this Section
2.2.

                                   ARTICLE III
                         OTHER AGREEMENTS OF THE PARTIES

      3.1   Transfer Restrictions.  (a) Securities may only be disposed of
pursuant to an effective registration statement under the Securities Act, to
the Company or pursuant to an available exemption from or in a transaction
not subject to the registration requirements of the Securities Act, and in
compliance with any applicable federal and state securities laws.  In
connection with any transfer of Securities other than pursuant to an
effective registration statement or to the Company, except as otherwise set
forth herein, the Company may require the transferor thereof to provide to
the Company an opinion of counsel selected by the transferor, the form and
substance of which opinion shall be reasonably satisfactory to the Company,
to the effect that such transfer does not require registration of such
transferred Securities under the Securities Act.  Any such transferee shall
agree in writing to be bound by the terms of this Agreement and shall have
the rights and obligations of a Purchaser under this Agreement and a Holder
under the Registration Rights Agreement.

            (b)   The Purchasers agree to the imprinting, so long as is
required by this Section 3.1(b), of the following legend on the Securities:

                                       -10-
<PAGE>   12

            NEITHER THESE SECURITIES [NOR THE SECURITIES INTO WHICH THESE
      SECURITIES ARE [CONVERTIBLE] [EXERCISABLE] HAVE BEEN REGISTERED WITH
      THE SECURITIES AND EXCHANGE COMMISSION OR THE SECURITIES COMMISSION OF
      ANY STATE IN RELIANCE UPON AN EXEMPTION FROM REGISTRATION UNDER THE
      SECURITIES ACT OF 1933, AS AMENDED (THE "SECURITIES ACT"), AND,
      ACCORDINGLY, MAY NOT BE OFFERED OR SOLD EXCEPT PURSUANT TO AN EFFECTIVE
      REGISTRATION STATEMENT UNDER THE SECURITIES ACT OR PURSUANT TO AN
      AVAILABLE EXEMPTION FROM, OR IN A TRANSACTION NOT SUBJECT TO, THE
      REGISTRATION REQUIREMENTS OF THE SECURITIES ACT AND IN ACCORDANCE WITH
      APPLICABLE STATE SECURITIES LAWS AS EVIDENCED BY A LEGAL OPINION OF
      COUNSEL TO THE TRANSFEROR TO SUCH EFFECT, THE SUBSTANCE OF WHICH SHALL
      BE REASONABLY ACCEPTABLE TO THE COMPANY.

            Underlying Shares shall not contain the legend set forth above
nor any other legend at any time while an Underlying Shares Registration
Statement is effective under the Securities Act or the holder of any such
security is relying on Rule 144 promulgated under the Securities Act ("Rule
144") in connection with the resale of such Underlying Shares or, in the
event there is not an effective Underlying Shares Registration Statement, at
such time and Rule 144 is not then available, if, in the opinion of counsel
to the Company, such legend is not required under applicable requirements of
the Securities Act (including judicial interpretations and pronouncements
issued by the staff of the Commission). The Company shall cause its counsel
to issue the legal opinion included in the Transfer Agent Instructions to the
Company's transfer agent on the day that the Underlying Shares Registration
Statement is declared effective by the Commission (the "Effective Date").
The Company agrees that, in the event any Underlying Shares are issued with a
legend in accordance with this Section 3.1(b), it will, within three (3)
Trading Days after request therefor by a Purchaser, provide such Purchaser
with a certificate or certificates representing such Underlying Shares, free
from such legend at such time as such legend would not have been required
under this Section 3.1(b) had such issuance occurred on the date of such
request.  The Company may not make any notation on its records or give
instructions to any transfer agent of the Company which enlarge the
restrictions of transfer set forth in this Section.

      3.2   Acknowledgment of Dilution.  The Company acknowledges that the
issuance of the Underlying Shares upon (i) conversion of the Shares in
accordance with the terms of the Certificate of Designation, and (ii)
exercise of the Warrants in accordance with their terms, will result in
dilution of the outstanding shares of Common Stock, which dilution may be
substantial under certain market conditions.  The Company further
acknowledges that its obligation to issue Underlying Shares upon (x)
conversion of the Shares in accordance with the terms of the Certificate of
Designation, and (y) exercise of the Warrants in accordance with their terms,
is unconditional and absolute, subject to the limitations set forth herein,
in the Certificate of Designation or pursuant to the Warrants, regardless of
the effect of any such dilution.

      3.3   Furnishing of Information.  As long as the Purchasers own
Securities, the Company covenants to timely file (or obtain extensions in
respect thereof and file within the applicable grace period) all reports
required to be filed by the Company after the date hereof pursuant to Section
13(a) or 15(d) of the Exchange Act.   As long as the Purchasers own
Securities, if the Company is not required to file reports pursuant to such
sections, it will prepare and furnish to the Purchasers and make publicly
available in accordance with Rule 144(c) promulgated under the Securities Act
such information as is required for the Purchasers to sell the Securities
under Rule 144 promulgated under the Securities Act.  The Company further
covenants that it will take such further action as any holder of Securities
may reasonably request, all to the extent required from time to time to
enable such Person to sell Underlying Shares without registration under the
Securities Act within the limitation of the exemptions provided by Rule 144
promulgated under the Securities Act, including in circumstances where an
exemption is available to the holder under the Securities Act causing its
attorneys to render and deliver any legal opinion required in order to permit
a Purchaser to receive Underlying Shares free of all restrictive legends and
to subsequently sell Underlying Shares under Rule 144 upon receipt of a
notice of an intention to sell or other form of notice having a similar
effect and related Form 144, brokers representation letter, sellers
representation letter and other documentation reasonably requested by such
counsel.  Upon the request of any such Person, the Company shall deliver to
such Person a written certification of a duly authorized officer as to
whether it has complied with such requirements.

      3.4   Integration.  The Company shall not, and shall use its best
efforts to ensure that, no Affiliate of the Company shall, sell, offer for
sale or solicit offers to buy or otherwise negotiate in respect of any
security (as defined in Section 2 of the Securities Act) that would be
integrated with the offer or sale of the Securities in a manner that would
require the registration under the Securities Act of the sale of the
Securities to the Purchasers, or that would be integrated with the offer or
sale of the Securities for the purposes of the rules and regulations of
NASDAQ.

      3.5   Increase in Authorized Shares.  If on any date the Company would
be, if a notice of conversion or exercise (as the case may be) were to be
delivered on such date, precluded from issuing (a) the number of Underlying
Shares as would then be issuable upon a conversion in full of the Shares, and
(b) the number of Underlying Shares as would then be issuable upon exercise
of the Warrants, assuming an exercise price of 75% of the then current
exercise price (the "Current Required Minimum"), in either case, due to the
unavailability of a sufficient number of authorized but unissued or reserved
shares of Common Stock, then the Board of Directors of the Company shall
promptly prepare and mail to the stockholders of the Company proxy materials
requesting authorization to amend the Company's certificate or articles of
incorporation to increase the number of shares of Common Stock which the
Company is authorized to issue to at least such number of shares as
reasonably requested by the Purchasers in order to provide for such number of
authorized and unissued shares of Common Stock to enable the Company to
comply with its issuance, conversion, exercise and reservation of shares
obligations as set forth in this Agreement, the Certificate of Designation
and the Warrants (the sum of (x) the number of shares of Common Stock then
outstanding plus all shares of Common Stock issuable upon exercise of all
outstanding options, warrants and convertible instruments, and (y) the
Current Required Minimum, shall be a reasonable number).  In connection
therewith, the Board of

                                       -12-
<PAGE>   14

Directors shall (a) adopt proper resolutions authorizing such increase, (b)
recommend to and otherwise use its best efforts to promptly and duly obtain
stockholder approval to carry out such resolutions (and hold a special meeting
of the stockholders no later than the earlier to occur of the 60th day after
delivery of the proxy materials relating to such meeting and the 90th day after
request by a holder of Securities to issue the number of Underlying Shares in
accordance with the terms hereof) and (c) within five Business Days of obtaining
such stockholder authorization, file an appropriate amendment to the Company's
certificate or articles of incorporation to evidence such increase.

      3.6   Reservation and Listing of Underlying Shares.  (a)  The Company
shall (i) in the time and manner required by the NASDAQ and any such other
exchange, market or quotation facility on which the Common Stock is traded,
prepare and file with the NASDAQ (and such national securities exchange,
market or trading or quotation facility on which the Common Stock is then
traded) an additional shares listing application covering a number of shares
of Common Stock which is not less than the Initial Minimum, (ii) take all
steps necessary to cause  such shares of Common Stock to be approved for
listing on the NASDAQ (as well as on any such other national securities
exchange or market or trading or quotation facility on which the Common Stock
is then listed) as soon as possible thereafter, and (iii) provide to the
Purchasers evidence of such listing, and the Company shall maintain the
listing of its Common Stock thereon. If the number of Underlying Shares
issuable upon conversion in full of the then outstanding Shares  and upon
exercise of the then unexercised portion of the Warrants exceeds 85% of the
number of Underlying Shares previously listed on account thereof with  NASDAQ
(and any such other required exchanges, then the Company shall take the
necessary actions to immediately list a number of Underlying Shares as equals
no less than the then Current Required Minimum.

            (b)  The Company shall maintain a reserve of shares of Common
Stock for issuance upon conversion of the Shares in full and upon exercise in
full of the Warrants in accordance with this Agreement, the Certificate of
Designation and the Warrants, respectively, in such amount as may be required
to fulfill its obligations in full under the Transaction Documents, which
reserve shall equal no less than the then Current Required Minimum.

      3.7   Conversion and Exercise Obligations and Procedures.  The Company
shall honor conversion of the Shares and exercise of the Warrants and shall
deliver Underlying Shares in accordance with the respective terms, conditions
and time periods set forth in the Certificate of Designation and Warrants.
The Transfer Agent Instructions,  Conversion Notice (as defined in the
Certificate of Designation) and Notice of Exercise under the Warrants set
forth the totality of the procedures with respect to the conversion of the
Shares and exercise of the Warrants, including the form of legal opinion, if
necessary, that shall be rendered to the Company's transfer agent and such
other information and instructions as may be reasonably necessary to enable
the Purchasers to convert their Shares and exercise their Warrants as
contemplated in the Certificate of Designation and the Warrants (as
applicable).

      3.8   Subsequent Financing; Limitation on Registrations.  (a) Subject
to Section 3.8(c) and (d), from the date hereof through the 180th Trading Day
following the Effective Date, the Company shall not, directly or indirectly,

<PAGE>   15

dispose of (or announce any offer, sale, grant or any option to purchase or
other disposition) (i) any of its equity or equity-equivalent securities or
securities of any of its Affiliates that are exchangeable or convertible
(directly or indirectly) for shares of Common Stock, including the issuance of
any debt or other instrument at any time over the life thereof convertible into
or exchangeable for Common Stock entitling any Person to acquire shares of
Common Stock that is senior or pari passu in right of payment, whether upon
liquidation or dissolution or otherwise to the Shares, (ii) any of its
non-derivative equity securities, at a price that is either (x) less than 80% of
the Per Share Market Value (as defined in the Certificate of Designation) on the
date of issuance thereof or (y) established by reference to the Per Share Market
Value or another market valuation to be determined at any date after the
issuance thereof or (iii) securities pursuant to an equity line of credit or
similar financing (collectively, a "Subsequent Placement") from the date hereof
until the expiration of the 180th Trading Day after the Effective Date, unless
(A) the Company delivers to each of the Purchasers a written notice (the
"Subsequent Placement Notice") of its intention to effect such Subsequent
Placement, which Subsequent Placement Notice shall describe in reasonable detail
the proposed terms of such Subsequent Placement, the amount of proceeds intended
to be raised thereunder, the Person with whom such Subsequent Placement shall be
effected, and attached to which shall be a term sheet or similar document
relating thereto and (B) such Purchaser shall not have notified the Company by

Subsequent Placement Notice of its willingness to provide (or to cause its sole
designee to provide), subject to completion of mutually acceptable
documentation, financing to the Company on the same terms set forth in the
Subsequent Placement Notice. If the Purchasers shall fail to notify the Company
of their intention to enter into such negotiations within such time period, the
Company may effect the Subsequent Placement substantially upon the terms and to
the Persons (or Affiliates of such Persons) set forth in the Subsequent
Placement Notice; provided, that the Company shall provide the Purchasers with a
second Subsequent Placement Notice, and the Purchasers shall again have the
right of first refusal set forth above in this paragraph (a), if the Subsequent
Placement subject to the initial Subsequent Placement Notice shall not have been
consummated for any reason on the terms set forth in such Subsequent Placement
Notice within 30 Trading Days after the date of the initial Subsequent Placement
Notice with the Person (or an Affiliate of such Person) identified in the
Subsequent Placement Notice. If the Purchasers shall indicate a willingness to
provide financing in excess of the amount set forth in the Subsequent Placement
Notice, then each Purchaser shall be entitled to provide financing pursuant to
such Subsequent Placement Notice up to an amount equal to such Purchaser's
pro-rata portion of the aggregate number of Shares purchased by such Purchaser
under this Agreement, but the Company shall not be required to accept financing
from the Purchasers in an amount in excess of the amount set forth in the
Subsequent Placement Notice.

            (b)   Except for (w) Underlying Shares, (x) other "Registrable

6(c) of the Registration Rights Agreement to be registered, in the Underlying
Shares Registration Statement in accordance with the Registration Rights
Agreement, (y) Common Stock issued pursuant to a primary offering by the
Company (which shall not include an equity line of credit or similar

securities pursuant to Regulation S promulgated under the Securities Act, or
(ii) register any securities of the Company. Any days after the Effective Date

Registration Statement shall be added to such 90 day period.

            (c)   With respect to Section 3.8(a) and (b), the 90 days and 180
Trading Day periods shall be extended for the number of Trading Days during

securities exchange or market or quotation system on which the Common Stock

and directors of the Company, and the issuance of Common Stock upon exercise

this Agreement and agrees that such service shall constitute good and
sufficient service of process and notice thereof.  Nothing contained herein
shall be deemed to limit in any way any right to serve process in any manner
permitted by law.

      4.9   Survival.  The representations, warranties, agreements and
covenants contained herein shall survive the Closing and the delivery and
conversion or exercise (as the case may be) of the Shares and of the
Warrants.

      4.10  Execution.  This Agreement may be executed in two or more
counterparts, all of which when taken together shall be considered one and
the same agreement and shall become effective when counterparts have been
signed by each party and delivered to the other party, it being understood
that both parties need not sign the same counterpart.  In the event that any
signature is delivered by facsimile transmission, such signature shall create
a valid and binding obligation of the party executing (or on whose behalf
such signature is executed) the same with the same force and effect as if
such facsimile signature page were an original thereof.

      4.11  Severability.  In case any one or more of the provisions of this
Agreement shall be invalid or unenforceable in any respect, the validity and
enforceability of the remaining terms and provisions of this Agreement shall
not in any way be affecting or impaired thereby and the parties will attempt
to agree upon a valid and enforceable provision which shall be a reasonable
substitute therefor, and upon so agreeing, shall incorporate such substitute
provision in this Agreement.

      4.12  Remedies.  In addition to being entitled to exercise all rights
provided herein or granted by law, including recovery of damages, each of the
Purchasers and the Company will be entitled to specific performance of each
other's obligations under the Transaction Documents.  The parties agree that
monetary damages may not be adequate compensation for any loss incurred by
reason of any breach of obligations described in the foregoing sentence and
hereby agree to waive in any action for specific performance of any such
obligation the defense that a remedy at law would be adequate.

      4.13  Independent Nature of Purchasers' Obligations and Rights.  The
obligations of each Purchaser under any Transaction Document is several and
not joint with the obligations of any other Purchaser and no Purchaser shall
be responsible in any way for the performance of the obligations of any other
Purchaser under any Transaction Document.  Nothing contained herein or in any
Transaction Document, and no action taken by any Purchaser pursuant thereto,
shall be deemed to constitute the Purchasers as a partnership, an
association, a joint venture or any other kind of entity, or create a
presumption that the Purchasers are in any way acting in concert with respect
to such obligations or the transactions contemplated by the Transaction
Document.  Each Purchaser shall be entitled to independently protect and
enforce its rights, including without limitation the rights arising out of
this Agreement or out of the other Transaction Documents, and it shall not be
necessary for any other Purchaser to be joined as an additional party in any
proceeding for such purpose.

                            TERMS OF PREFERRED STOCK

      Section 1.  Designation, Amount and Par Value.  The series of preferred
stock shall be designated as its 6% Series A Convertible Preferred Stock (the
"Preferred Stock") and the number of shares so designated shall be 800 (which
shall not be subject to increase without the consent of the holders of the
Preferred Stock (each, a "Holder" and collectively, the "Holders")).  Each
share of Preferred Stock shall have a par value of $.01 per share and a
stated value equal to the sum of $10,000 plus all accrued and unpaid
dividends to the date of determination to the extent not previously paid in
cash in accordance with the terms hereof (the "Stated Value").

      Section 2.  Dividends.

            (a)  Holders shall be entitled to receive, out of funds legally
available therefor, and the Company shall pay, cumulative dividends at the
rate per share (as a percentage of the Stated Value per share) of 6% per
annum, payable on each Conversion Date (as defined herein) for such share, in
cash or by accretion of the Stated Value.  Subject to the terms and
conditions herein, the decision whether to accrete dividends hereunder to the
Stated Value or to pay for dividends in cash shall be at the discretion of
the Company.  The Company shall provide the Holders written notice of its
intention to accrete dividends hereunder to the Stated Value or pay dividends
in cash not less than ten days prior to each Conversion  Date for so long as
shares of Preferred Stock are outstanding (the Company may indicate in such
notice that the election contained in such notice shall continue for later
periods until revised).  Failure to timely provide such written notice shall
be deemed (if permitted hereunder) an election by the Company to accrete
dividends hereunder to the Stated Value.  Dividends on the Preferred Stock
shall be calculated on the basis of a 360-day year, shall accrue daily
commencing on the Original Issue Date (as defined in Section 8), and shall be
deemed to accrue from such date whether or not earned or declared and whether
or not there are profits, surplus or other funds of the Company legally
available for the payment of dividends.  Except as otherwise provided herein,
if at any time the Company pays less than the total amount of dividends then
accrued on account of the Preferred Stock, such payment shall be distributed
ratably among the Holders based upon the number of shares of Preferred Stock
held by each Holder. Any dividends to be paid in cash hereunder that are not
paid within three Trading Days (as defined in Section 8) following a
Conversion Date shall continue to accrue and shall entail a late fee, which
must be paid in cash, at the rate of 18% per annum or the lesser rate
permitted by applicable law (such fees to accrue daily, from the date such
dividend is due hereunder through and including the date of payment).

            (b)  Notwithstanding anything to the contrary contained herein
and subject to applicable legal requirements, the Company must pay dividends
in cash if:

                  (i)  the number of shares of Common Stock (as defined in
Section 8) at the time authorized, unissued and unreserved for all purposes
is insufficient to accrete such dividends to the Stated Value to permit
conversion in full of all outstanding Stated Value;

                                      A-1
<PAGE>   26
                   (ii) after the Dividend Effectiveness Date (as defined in
Section 8), Underlying Shares (as defined in Section 8) (x) are not
registered for resale pursuant to an effective Underlying Shares Registration
Statement (as defined in Section 8) and (y) may not be sold without volume
restrictions pursuant to Rule 144(k) promulgated under the Securities Act (as
defined in Section 8), (if the Company is permitted and elects to pay
dividends in shares of Common Stock under this clause (ii) prior to the
Dividend Effectiveness Date and thereafter an Underlying Shares Registration
Statement shall be declared effective by the Commission (as defined in
Section 8), the Company shall, within three Trading Days after the date of
such declaration of effectiveness, exchange such Underlying Shares for shares
of Common Stock that are free of restrictive legends of any kind);

                  (iii) the Common Stock is not then listed or quoted on the
Nasdaq National Market (the "Nasdaq"), or on the New York Stock Exchange,
American Stock Exchange or Nasdaq SmallCap Market (each, a "Subsequent
Market"); or

                  (iv)  the accretion of such dividends to the Stated Value
and subsequent conversions of all then outstanding Stated Value would result
in a violation of Section 5(a)(iii) or the rules of the Nasdaq or any other
rules and regulations governing any Subsequent Market on which the Common
Stock is then listed or quoted for trading.

            (c)   So long as any Preferred Stock shall remain outstanding,
neither the Company nor any subsidiary thereof shall redeem, purchase or
otherwise acquire directly or indirectly any Junior Securities (as defined in
Section 8), nor shall the Company directly or indirectly pay or declare any
dividend or make any distribution (other than a dividend or distribution
described in Section 5 or dividends due and paid in the ordinary course on
preferred stock of the Company at such times when the Company is in
compliance with its payment and other obligations hereunder) upon, nor shall
any distribution be made in respect of, any Junior Securities, nor shall any
monies be set aside for or applied to the purchase or redemption (through a
sinking fund or otherwise) of any Junior Securities or shares pari passu with
the Preferred Stock.

            Section 3.  Voting Rights.   Except as otherwise provided herein
and as otherwise required by law, the Preferred Stock shall have no voting
rights.  However, so long as any shares of Preferred Stock are outstanding,
the Company shall not, without the affirmative vote of the Holders of a
majority of the shares of the Preferred Stock then outstanding, (a) alter or
change adversely the powers, preferences or rights given to the Preferred
Stock or alter or amend this Certificate of Designation, (b) authorize or
create any class of stock ranking as to dividends or distribution of assets
upon a Liquidation (as defined in Section 4) senior to or otherwise pari
passu with the Preferred Stock, (c) amend its certificate or articles of
incorporation or other charter documents so as to affect adversely any rights
of the Holders, (d) increase the authorized number of shares of Preferred
Stock, or (e) enter into any agreement with respect to the foregoing.

            Section 4.  Liquidation.  Upon any liquidation, dissolution or
winding-up of the Company, whether voluntary or involuntary (a
"Liquidation"), the Holders shall be entitled to

                                      A-2
<PAGE>   27

receive out of the assets of the Company, whether such assets are capital or
surplus, for each share of Preferred Stock an amount equal to the Stated Value
per share before any distribution or payment shall be made to the holders of any
Junior Securities, and if the assets of the Company shall be insufficient to pay
in full such amounts, then the entire assets to be distributed to the Holders
shall be distributed among the Holders ratably in accordance with the respective
amounts that would be payable on such shares if all amounts payable thereon were
paid in full. A sale, conveyance or disposition of 50% or more of the assets of
the Company or the effectuation by the Company of a transaction or series of
related transactions in which more than 33% of the voting power of the Company
is disposed of, or a consolidation or merger of the Company with or into any
other company or companies into one or more companies not wholly-owned by the
Company shall not be treated as a Liquidation, but instead shall be subject to
the provisions of Section 5. The Company shall mail written notice of any such
Liquidation, not less than 45 days prior to the payment date stated therein, to
each record Holder.

            Section 5.  Conversion.

            (a)(i) Conversions at Option of Holder.  Each share of Preferred
Stock shall be convertible into shares of Common Stock (subject to the
limitations set forth in Section (a)(iii)) at the Conversion Ratio (as
defined in Section 8), at the option of the Holder, at any time and from time
to time from and after the Original Issue Date.  Holders shall effect
conversions by providing the Company with the form of conversion notice
attached hereto as Exhibit A (a "Holder Conversion Notice").  Each Holder
Conversion Notice shall specify the number of shares of Preferred Stock to be
converted, the number of shares of Preferred Stock owned prior to the
conversion at issue, number of shares of Preferred Stock owned subsequent to
the conversion at issue and the date on which such conversion is to be
effected, which date may not be prior to the date the Holder delivers such
Conversion Notice by facsimile (the "Holder Conversion Date"). The number of
shares of Preferred Stock shown as owned by the Holder prior to and giving
effect to a conversion shall control absent manifest or mathematical error.
If no Holder Conversion Date is specified in a Holder Conversion Notice, the
Holder Conversion Date shall be the date that such Holder Conversion Notice
is deemed delivered hereunder.  To effect conversions of Preferred Stock, a
Holder shall not be required to surrender the certificate(s) representing
such shares of Preferred Stock to the Company unless all of the shares of
Preferred Stock represented thereby are so converted.

                  (ii) Conversion At Option of the Company.   If at any time
after the Effective Date, the Closing Price for 20 consecutive Trading Days
exceeds 130% of Conversion Price on the Original Issue Date (subject to
equitable adjustment for stock splits, recombinations and similar events
pursuant to Section 4(c)(ii)), the Company may require the Holder to convert
all or any portion of the Preferred Stock (subject to the limitations set
forth in Section 5(a)(iii)) at the Conversion Ratio. provided, that the
Company shall not be permitted to deliver a Company Conversion Notice (as
defined below) at any time when the Underlying Securities Registration
Statement is not then effective or shares of Common Stock are not actively
traded on the Nasdaq National Market ("NASDAQ") or listed or quoted for
trading on the New York Stock Exchange, American Stock Exchange or Nasdaq
SmallCap Market (each, a "Subsequent Market") and provided further that the
Closing Price must equal or exceed the price required pursuant to this
sentence on

                                      A-3

<PAGE>   28

the Company Conversion Date. The Company shall effect such conversion by
delivering to the Holder a written notice in the form attached hereto as Exhibit
B (the "Company Conversion Notice"), which Company Conversion Notice, once
given, shall be irrevocable. Each Company Conversion Notice shall specify the
number of shares of Preferred Stock to be converted. The date of delivery of the
Company Conversion Notice is referred to herein as the "Company Conversion
Date". A Holder Conversion Notice and a Company Conversion Notice may sometimes
be referred to as a "Conversion Notice". A Holder Conversion Date and a Company
Conversion Date may sometimes be referred to as a "Conversion Date".

                  (iii) Certain Conversion Restrictions.

                  (A)  A Holder may not convert or be required to convert
shares of Preferred Stock or receive shares of Common Stock as payment of
dividends hereunder to the extent such conversion or receipt of such dividend
payment would result in the Holder, together with any affiliate thereof,
beneficially owning (as determined in accordance with Section 13(d) of the
Exchange Act (as defined in Section 8) and the rules promulgated thereunder)
in excess of 4.999% of the then issued and outstanding shares of Common
Stock, including shares issuable upon conversion of, and payment of dividends
on, the shares of Preferred Stock held by such Holder after application of
this Section.  Since the Holder will not be obligated to report to the
Company the number of shares of Common Stock it may hold at the time of a
conversion hereunder, unless the conversion at issue would result in the
issuance of shares of Common Stock in excess of 4.999% of the then
outstanding shares of Common Stock without regard to any other shares which
may be beneficially owned by the Holder or an affiliate thereof, the Holder
shall have the authority and obligation to determine whether the restriction
contained in this Section will limit any particular conversion hereunder and
to the extent that the Holder determines that the limitation contained in
this Section applies, the determination of which portion of the shares of
Preferred Stock are convertible shall be the responsibility and obligation of
the Holder.  If the Holder has delivered a Conversion Notice for shares of
Preferred Stock that, without regard to any other shares that the Holder or
its affiliates may beneficially own,  would result in the issuance in excess
of the permitted amount hereunder, the Company shall notify the Holder of
this fact and shall honor the conversion for the maximum number of shares of
Preferred Stock permitted to be converted on such Conversion Date in
accordance with the periods described in Section 5(b) and, at the option of
the Holder, either retain shares of Preferred Stock tendered for conversion
in excess of the permitted amount hereunder for future conversions or return
such excess shares of Preferred Stock permitted to the Holder.  The
provisions of this Section may be waived by a Holder (but only as to itself
and not to any other Holder) upon not less than 61 days prior notice to the
Company. Other Holders shall be unaffected by any such waiver.

                  (B)  A Holder may not convert or be required to convert
shares of Preferred Stock or receive shares of Common Stock as payment of
dividends hereunder to the extent such conversion or receipt of such dividend
payment would result in the Holder, together with any affiliate thereof,
beneficially owning (as determined in accordance with Section 13(d) of the
Exchange Act and the rules promulgated thereunder) in excess of 9.999% of the
then issued and outstanding shares of Common Stock, including shares issuable
upon conversion of, and payment of dividends on, the shares of Preferred
Stock held by such Holder after application of this Section.

                                      A-4

<PAGE>   29

Since the Holder will not be obligated to report to the Company the number of
shares of Common Stock it may hold at the time of a conversion hereunder, unless
the conversion at issue would result in the issuance of shares of Common Stock
in excess of 9.999% of the then outstanding shares of Common Stock without
regard to any other shares which may be beneficially owned by the Holder or an
affiliate thereof, the Holder shall have the authority and obligation to
determine whether the restriction contained in this Section will limit any
particular conversion hereunder and to the extent that the Holder determines
that the limitation contained in this Section applies, the determination of
which portion of the shares of Preferred Stock are convertible shall be the
responsibility and obligation of the Holder. If the Holder has delivered a
Conversion Notice for shares of Preferred Stock that, without regard to any
other shares that the Holder or its affiliates may beneficially own, would
result in the issuance in excess of the permitted amount hereunder, the Company
shall notify the Holder of this fact and shall honor the conversion for the
maximum number of shares of Preferred Stock permitted to be converted on such
Conversion Date in accordance with the periods described in Section 5(b) and, at
the option of the Holder, either retain shares of Preferred Stock tendered for
conversion in excess of the permitted amount hereunder for future conversions or
return such excess shares of Preferred Stock permitted to the Holder. The
provisions of this Section may be waived by a Holder (but only as to itself and
not to any other Holder) upon not less than 61 days prior notice to the Company.
Other Holders shall be unaffected by any such waiver.

                  (C)   If the Common Stock is then listed for trading on the
Nasdaq or the Nasdaq SmallCap Market and the Company has not obtained the
Shareholder Approval (as defined below), then the Company may not issue in
excess of 3,492,001.9 shares of Common Stock (which equals 19.999% of the
number of shares of Common Stock outstanding on the Trading Day immediately
preceding the Original Closing Date) upon conversions of Preferred Stock and
exercise of Redemption Warrants and Closing Warrants (each as defined in the
Purchase Agreement), in either case, at a price per share that is less than
the Per Share Market Value on the Trading Day immediately preceding the
Original Issue Date (such number of shares, the "Issuable Maximum").  Each
Holder shall be entitled to a portion of the Issuable Maximum equal to the
quotient obtained by dividing (x) the number of shares of Preferred Stock
issued and sold to such Holder on the Original Issue Date by (y) the number
of shares of Preferred Stock issued and sold by the Company on the Original
Issue Date.  If any Holder shall no longer hold shares of Preferred Stock,
then such Holder's remaining portion of the Issuable Maximum shall be
allocated pro-rata among the remaining Holders.  If on any Conversion Date
(A) the shares of Common Stock are listed for trading on the Nasdaq or Nasdaq
SmallCap Market, (B) the Conversion Price then in effect is such that the
aggregate number of shares of Common Stock that would then be issuable upon
conversion in full of all then outstanding shares of Preferred Stock and
exercise in full of the Redemption Warrants and Closing Warrants, together
with any shares of  Common Stock previously issued upon conversion of shares
of Preferred Stock and exercise in full of the Redemption Warrants and
Closing Warrants would exceed the Issuable Maximum, and (C) the Company shall
not have previously obtained the vote of shareholders (the "Shareholder
Approval"), if any, as may be required by the applicable rules and
regulations of the Nasdaq (or any successor entity) applicable to approve the
issuance of shares of Common Stock  in excess of the Issuable Maximum
pursuant to the terms hereof, then the Company shall issue to the Holder
requesting a conversion a number of shares of Common Stock  equal to such
Holder's pro-rata portion (which shall be calculated pursuant to the

terms hereof) of the Issuable Maximum and, with respect to the remainder of the
aggregate Stated Value of the shares of Preferred Stock then held by such Holder
for which a conversion in accordance with the Conversion Price would result in
an issuance of shares of Common Stock in excess of such Holder's pro-rata
portion (which shall be calculated pursuant to the terms hereof) of the Issuable
Maximum (the "Excess Stated Value"), the converting Holder shall have the option
to require the Company to either: (1) use its best efforts to obtain the
Shareholder Approval applicable to such issuance as soon as is possible, but in
any event not later than the 60th day after such request, or (2) pay cash to the
converting Holder in an amount equal to the Mandatory Redemption Amount (as
defined in Section 8) for the Excess Stated Value. If the converting Holder
shall have elected the first option pursuant to the immediately preceding
sentence and the Company shall have failed to obtain the Shareholder Approval on
or prior to the 60th day after such request, then within three (3) days of such
60th day, the Company shall pay cash to the converting Holder an amount equal to
the Mandatory Redemption Amount for the Excess Stated Value. If the Company
fails to pay the Mandatory Redemption Amount in full pursuant to this Section
within seven days after the date payable, the Company will pay interest thereon
at a rate of 18% per annum or such lesser maximum amount that is permitted to be
paid by applicable law, to the converting Holder, accruing daily from the
Conversion Date until such amount, plus all such interest thereon, is paid in
full. The Company and the Holder understand and agree that shares of Common
Stock issued to and then held by the Holder as a result of conversions of
Preferred Stock shall not be entitled to cast votes on any resolution to obtain
Shareholder Approval pursuant hereto.

            (b)(i) Not later than five Trading Days after each Conversion
Date, the Company will deliver to the Holder (A) a certificate or
certificates which shall be free of restrictive legends and trading
restrictions (other than those required by Section 3.1(b) of the Purchase
Agreement) representing the number of shares of Common Stock being acquired
upon the conversion of shares of Preferred Stock, and (B) a bank check in the
amount of accrued and unpaid dividends (if the Company has elected or is
required to pay accrued dividends in cash). The Company shall, upon request
of the Holder, if available, use its best efforts to deliver any certificate
or certificates required to be delivered by the Company under this Section
electronically through the Depository Trust Corporation or another
established clearing corporation performing similar functions.  If in the
case of any Conversion Notice such certificate or certificates are not
delivered to or as directed by the applicable Holder by the fifth Trading Day
after the Conversion Date, the Holder shall be entitled to elect by written
notice to the Company at any time on or before its receipt of such
certificate or certificates thereafter, to rescind such conversion, in which
event the Company shall immediately return the certificates representing the
shares of Preferred Stock tendered for conversion.

                  (ii) If the Company fails to deliver to the Holder such
certificate or certificates pursuant to Section 5(b)(i), by the fifth Trading
Day after the Conversion Date, the Company shall pay to such Holder, in cash,
as liquidated damages and not as a penalty, $5,000 for each Trading Day after
such fifth Trading Day until such certificates are delivered. Nothing herein
shall limit a Holder's right to pursue actual damages for the Company's
failure to deliver certificates representing shares of Common Stock upon
conversion within the period specified herein and such Holder shall have the
right to pursue all remedies available to it hereunder, at law or in equity
including, without limitation, a decree of specific performance and/or
injunctive relief.

                                      A-6
<PAGE>   31

                  (iii)  In addition to any other rights available to the
Holder, if the Company fails to deliver to the Holder such certificate or
certificates pursuant to Section 5(b)(i), by the fifth Trading Day after the
Conversion Date, and if after such fifth Trading Day the Holder purchases (in
an open market transaction or otherwise) Common Stock to deliver in
satisfaction of a sale by such Holder of the Underlying Shares (with respect
to which the Holder was unable to utilize borrowed shares for such purpose
due to the inability or unwillingness of the broker of such Holder to loan
such shares to such Holder) which the Holder was entitled to receive upon
such conversion (a "Buy-In"), then the Company shall (A) pay in cash to the
Holder the amount by which (x) the Holder's total purchase price (including
brokerage commissions, if any) for the Common Stock so purchased exceeds (y)
the product of (1) the aggregate number of shares of Common Stock that such
Holder was entitled to receive from the conversion at issue multiplied by (2)
the market price of the Common Stock at the time of the sale giving rise to
such purchase obligation and (B) at the option of the Holder, either return
the shares of Preferred Stock for which such conversion was not honored or
deliver to such Holder the number of shares of Common Stock that would have
been issued had the Company timely complied with its conversion and delivery
obligations under Section 5(b)(i).  For example, if the Holder purchases
Common Stock having a total purchase price of $11,000 to cover a Buy-In with
respect to an attempted conversion of shares of Preferred Stock with respect
to which the market price of the Underlying Shares on the date of conversion
totaled $10,000, under clause (A) of the immediately preceding sentence the
Company shall be required to pay the Holder $1,000.  The Holder shall provide
the Company written notice indicating the amounts payable to the Holder in
respect of the Buy-In.  Nothing herein shall limit a Holder's right to pursue
any other remedies available to it hereunder, at law or in equity including,
without limitation, a decree of specific performance and/or injunctive relief
with respect to the Company's failure to timely deliver certificates
representing shares of Common Stock upon conversion of the shares of
Preferred Stock as required pursuant to the terms hereof.

            (c)(i)  The conversion price for each share of Preferred Stock
in effect on any Conversion Date shall be $7.00 (the "Conversion Price").

                  (ii)  If the Company, at any time while any shares of
Preferred Stock are outstanding, shall (a) pay a stock dividend or otherwise
make a distribution or distributions on shares of its Junior Securities or
pari passu securities payable in shares of Common Stock, (b) subdivide
outstanding shares of Common Stock into a larger number of shares, (c)
combine (including by way of reverse stock split) outstanding shares of
Common Stock into a smaller number of shares, or (d) issue by
reclassification and exchange of the Common Stock any shares of capital stock
of the Company, then the Conversion Price shall be multiplied by a fraction
of which the numerator shall be the number of shares of  Common Stock
(excluding treasury shares, if any) outstanding before such event and of
which the denominator shall be the number of shares of Common Stock
outstanding after such event.  Any adjustment made pursuant to this Section
5(c)(ii) shall become effective immediately after the record date for the
determination of stockholders entitled to receive such dividend or
distribution and shall become effective immediately after the effective date
in the case of a subdivision, combination or re-classification.

                                      A-7
<PAGE>   32

                  (iii) If the Company, at any time while any shares of
Preferred Stock are outstanding, shall issue rights, warrants or options to
all holders of Common Stock (and not to Holders) entitling them to subscribe
for or purchase shares of Common Stock at a price per share less than the Per
Share Market Value at the record date mentioned below, then the Conversion
Price shall be multiplied by a fraction, the numerator of which shall be the
number of shares of Common Stock outstanding immediately prior to the
issuance of such rights, warrants or options, plus the number of shares of
Common Stock which the aggregate offering price of the total number of shares
so offered would purchase at such Per Share Market Value, and the denominator
of which shall be the sum of the number of shares of Common Stock outstanding
immediately prior to such issuance plus the number of shares of Common Stock
offered for subscription or purchase.  Such adjustment shall be made whenever
such rights or warrants are issued, and shall become effective immediately
after the record date for the determination of stockholders entitled to
receive such rights or warrants.  However, upon the expiration of any right,
warrant or option to purchase shares of Common Stock the issuance of which
resulted in an adjustment in the Conversion Price pursuant to this Section
5(c)(iii), if any such right, warrant or option shall expire and shall not
have been exercised, the Conversion Price shall immediately upon such
expiration shall be recomputed and effective immediately upon such expiration
shall be increased to the price which it would have been (but reflecting any
other adjustments in the Conversion Price made pursuant to the provisions of
this Section 5 upon the issuance of other rights or warrants) had the
adjustment of the Conversion Price made upon the issuance of such rights,
warrants, or options  been made on the basis of offering for subscription or
purchase only that number of shares of Common Stock actually purchased upon
the exercise of such rights, warrants or options actually exercised.

                  (iv)  If the Company or any subsidiary thereof, as
applicable with respect to Common Stock Equivalents (as defined below), at
any time while any shares of Preferred Stock are outstanding, shall issue
shares of Common Stock or rights, warrants (including the issuance of shares
of Common Stock upon exercise of warrants issued to the Purchasers under the
Purchase Agreement), options or other securities or debt that is convertible
into or exchangeable for shares of Common Stock ("Common Stock Equivalents")
entitling any Person to acquire shares of Common Stock, at a price per share
less than the Conversion Price (if the holder of the Common Stock or Common
Stock Equivalent so issued shall at any time, whether by operation of
purchase price adjustments, reset provisions, floating conversion, exercise
or exchange prices or otherwise, or due to warrants, options or rights issued
in connection with such issuance, be entitled to receive shares of Common
Stock at a price less than the Conversion Price, such issuance shall be
deemed to have occurred for less than the Conversion Price), then, at the
option of the Holder, the Conversion Price shall be replaced with the
conversion, exchange or purchase price for such Common Stock or Common Stock
Equivalents (including any reset provisions thereof) for all subsequent
conversions of Preferred Stock or such conversions as shall be indicated by
the Holder on its Conversion Notice.  Such adjustment shall be made whenever
such Common Stock or Common Stock Equivalents are issued.  The Company shall
notify the Holder in writing, no later than the Trading Day following the
issuance of any Common Stock or Common Stock Equivalent subject to this
section, of the issuance of such Common Stock or Common Stock Equivalent (or
of such agent pursuant to which such Common Stock or Common Stock Equivalent
may be issued, indicating therein the applicable issuance price, or of
applicable reset price, exchange price, exercise

                                      A-8

price, conversion price and other pricing terms. Notwithstanding to the contrary
anything herein, this Section shall not apply to: (i) issuance of options and
warrants to employees, officers and directors of the Company, and the issuance
of Common Stock upon exercise of such options and warrants granted under any
stock option agreements and stock option plans heretofore issued or adopted by
the Company and any stock option plan hereinafter duly adopted by the Company,
(ii) issuance of Common Stock or Common Stock Equivalents as part payment of the
purchase price in (A) the acquisition of assets or a business by the Company or
(B) in connection with the acquisition of goods or a license by the Company and
(iii) as royalty payments in connection with or under a firm underwritten
primary offering of the Company's stock in which the full purchase price is paid
upon the first closing thereof (which shall not include equity lines of credit
or any similar financing structure).

                  (v)    If the Company, at any time while shares of
Preferred Stock are outstanding, shall distribute to all holders of Common
Stock (and not to Holders) evidences of its indebtedness or assets or rights
or warrants to subscribe for or purchase any security (excluding those
referred to in Sections 5(c)(ii)-(iv) above), then in each such case the
Conversion Price at which each share of Preferred Stock shall thereafter be
convertible shall be determined by multiplying the Conversion Price in effect
immediately prior to the record date fixed for determination of stockholders
entitled to receive such distribution by a fraction of which the denominator
shall be the Per Share Market Value determined as of the record date
mentioned above, and of which the numerator shall be such Per Share Market
Value on such record date less the then fair market value at such record date
of the portion of such assets or evidence of indebtedness so distributed
applicable to one outstanding share of Common Stock as determined by the
Board of Directors in good faith.  In either case the adjustments shall be
described in a statement provided to the Holders of the portion of assets or
evidences of indebtedness so distributed or such subscription rights
applicable to one share of Common Stock.  Such adjustment shall be made
whenever any such distribution is made and shall become effective immediately
after the record date mentioned above.

                  (vi)  All calculations under this Section 5 shall be made
to the nearest cent or the nearest 1/100th of a share, as the case may be.
The number of shares of Common Stock outstanding at any given time shall not
include shares owned or held by or for the account of the Company, and the
disposition of any such shares shall be considered an issue or sale of Common
Stock.

                  (vii) Whenever the Conversion Price is adjusted pursuant to
Section 5(c)(ii),(iii), (iv) or (v) the Company shall promptly mail to each
Holder, a notice setting forth the Fixed Conversion Price or the Conversion
Price (as applicable) after such adjustment and setting forth a brief
statement of the facts requiring such adjustment.

                  (viii)      In case of any reclassification of the Common
Stock, or any compulsory share exchange pursuant to which the Common Stock is
converted into other securities, cash or property (other than compulsory
share exchanges which constitute Change of Control Transactions), the Holders
of the Preferred Stock then outstanding shall have the right thereafter to
convert such shares only into the shares of stock and other securities, cash
and property receivable

                                      A-9
<PAGE>   34

upon or deemed to be held by holders of Common Stock following such
reclassification or share exchange, and the Holders of the Preferred Stock shall
be entitled upon such event to receive such amount of securities, cash or
property as a holder of the number of shares of Common Stock of the Company into
which such shares of Preferred Stock could have been converted immediately prior
to such reclassification or share exchange would have been entitled. This
provision shall similarly apply to successive reclassifications or share
exchanges.

                  (ix)  In case of any merger or consolidation of the Company
with or into another Person, or sale by the Company of more than one-half of
the assets of the Company (on an as valued basis) in one or a series of
related transactions, a Holder shall have the right thereafter to: (A)
convert its shares of Preferred Stock into the shares of stock and other
securities, cash and property receivable upon or deemed to be held by holders
of Common Stock following such merger, consolidation or sale, and such Holder
shall be entitled upon such event or series of related events to receive such
amount of securities, cash and property as the shares of Common Stock into
which such shares of Preferred Stock could have been converted immediately
prior to such merger, consolidation or sales would have been entitled or (B)
in the case of a merger or consolidation, require the Company to pay to the
Holder, in cash,120% of the Stated Value of the shares of Preferred Stock
then held by such Holder.  The terms of any such merger, sale or
consolidation shall include such terms so as continue to give the Holders the
right to receive the securities, cash and property set forth in this Section
upon any conversion or redemption following such event. This provision shall
similarly apply to successive such events.  The rights set forth in this
Section 5(c)(ix) shall not alter the rights of a Holder set forth in Section
7, provided, that, a Holder may only exercise the rights set forth in this
Section 5(c)(ix) or the rights set forth in Section 7 with respect to a
single event giving rise to such rights.

                  (x)    If (a) the Company shall declare a dividend (or any
other distribution) on the Common Stock, (b) the Company shall declare a
special nonrecurring cash dividend on or a redemption of the Common Stock,
(c) the Company shall authorize the granting to all holders of Common Stock
rights or warrants to subscribe for or purchase any shares of capital stock
of any class or of any rights, (d) the approval of any stockholders of the
Company shall be required in connection with any reclassification of the
Common Stock, any consolidation or merger to which the Company is a party,
any sale or transfer of all or substantially all of the assets of the
Company, or any compulsory share of exchange whereby the Common Stock  is
converted into other securities, cash or property, or (e) the Company shall
authorize the voluntary or involuntary dissolution, liquidation or winding up
of the affairs of the Company; then the Company shall notify the Holders at
their last addresses as they shall appear upon the stock books of the
Company, at least 20 calendar days prior to the applicable record or
effective date hereinafter specified, a notice stating (x) the date on which
a record is to be taken for the purpose of such dividend, distribution,
redemption, rights or warrants, or if a record is not to be taken, the date
as of which the holders of Common Stock of record to be entitled to such
dividend, distributions, redemption, rights or warrants are to be determined
or (y) the date on which such reclassification, consolidation, merger, sale,
transfer or share exchange is expected to become effective or close, and the
date as of which it is expected that holders of Common Stock of record shall
be entitled to exchange their Common Stock for securities, cash or other
property deliverable upon such reclassification, consolidation, merger, sale,
transfer

                                  A-10
<PAGE>   35
or share exchange. Holders are entitled to convert shares of Preferred Stock
during the 20-day period commencing the date of such notice to the effective
date of the event triggering such notice.

            (d)  The Company covenants that it will at all times reserve and
keep available out of its authorized and unissued shares of Common Stock
solely for the purpose of issuance upon conversion of Preferred Stock, each
as herein provided, free from preemptive rights or any other actual
contingent purchase rights of persons other than the Holders, not less than
such number of shares of Common Stock as shall be issuable (taking into
account the provisions of Section 5(a) and Section 5(c)) upon the conversion
of all outstanding shares of Preferred Stock.  The Company covenants that all
shares of Common Stock that shall be so issuable shall, upon issue, be duly
and validly authorized, issued and fully paid and nonassessable.

            (e)  Upon a conversion hereunder the Company shall not be
required to issue stock certificates representing fractions of shares of
Common Stock, but may if otherwise permitted, make a cash payment in respect
of any final fraction of a share based on the Per Share Market Value at such
time.  If any fraction of an Underlying Share would, except for the
provisions of this Section, be issuable upon a conversion hereunder, the
Company shall pay an amount in cash equal to the Conversion Ratio multiplied
by such fraction.

            (f)  The issuance of certificates for Common Stock on conversion
of Preferred Stock shall be made without charge to the Holders thereof for
any documentary stamp or similar taxes that may be payable in respect of the
issue or delivery of such certificate, provided that the Company shall not be
required to pay any tax that may be payable in respect of any transfer
involved in the issuance and delivery of any such certificate upon conversion
in a name other than that of the Holder of such shares of Preferred Stock so
converted.

            (g)  Shares of Preferred Stock converted into Common Stock or
redeemed in accordance with the terms hereof shall be canceled and may not be
reissued.

            (h)  Any and all notices or other communications or deliveries
to be provided by the Holders of the Preferred Stock hereunder, including,
without limitation, any Conversion Notice, shall be in writing and delivered
personally, by facsimile or sent by a nationally recognized overnight courier
service, addressed to the attention of the Chief Financial Officer of the
Company addressed to 499 Thornall Street, Edison, New Jersey 08837 Facsimile
No.: 732-362-2123, attention Chief Financial Officer, or to such other
address or facsimile number as shall be specified in writing by the Company
for such purpose.  Any and all notices or other communications or deliveries
to be provided by the Company hereunder shall be in writing and delivered
personally, by facsimile or sent by a nationally recognized overnight courier
service, addressed to each Holder at the facsimile telephone number or
address of such Holder appearing on the books of the Company, or if no such
facsimile telephone number or address appears, at the principal place of
business of the Holder.  Any notice or other communication or deliveries
hereunder shall be deemed given and effective on the earliest of (i) the date
of transmission, if such notice or communication is delivered via facsimile
at the facsimile telephone number specified in this Section prior to 6:30
p.m. (New York City time) (with confirmation of transmission), (ii) the date
after the date of transmission, if such notice or

                                      A-11
<PAGE>   36

communication is delivered via facsimile at the facsimile telephone number
specified in this Section later than 6:30 p.m. (New York City time) on any date
and earlier than 11:59 p.m. (New York City time) on such date (with confirmation
of transmission), (iii) upon receipt, if sent by a nationally recognized
overnight courier service, or (iv) upon actual receipt by the party to whom such
notice is required to be given.

      Section 6.  Optional Redemption.

            (a)  The Company shall have the right, subject to the provisions
of this Section 6, upon a 30 Trading Day prior written notice (an "Optional
Redemption Notice" and the date such Optional Redemption Notice is received
by a Holder, an "Optional Redemption Date") to the Holders, to redeem all or
any portion of the shares of Preferred Stock which have not previously been
redeemed or for which Conversion Notices shall not have been delivered, at a
price equal to the Optional Redemption Price (as defined in Section 8).  The
Company may only deliver an Optional Redemption Notice if: (i)  the number of
shares of Common Stock at the time authorized, unissued and unreserved for
all purposes is sufficient to satisfy the Company's conversion obligations of
all shares of Preferred Stock then outstanding, (ii) the Underlying Shares
then outstanding are registered for resale pursuant to an effective
Underlying Shares Registration Statement pursuant to which the Holders are
permitted to sell Underlying Shares or the Underlying Shares may be resold
without volume restrictions pursuant to Rule 144(k) promulgated under the
Securities Act, and (iii) the Common Stock is listed for trading on the
Nasdaq or on a Subsequent Market.  In order for an Optional Redemption Notice
to remain in effect subsequent to the Optional Redemption Date, each of
clauses (i) - (iii) of the immediately preceding sentence must be true during
the entire 30 Trading Days between the Optional Redemption Date and the date
of payment of the Optional Redemption Price.  The entire Optional Redemption
Price shall be paid in cash.  A Holder may convert (and the Company shall
honor such conversions in accordance with the terms hereof) any or all of the
shares of Preferred Stock subject to an Optional Redemption Notice delivered
for conversion on or prior to the 30th Trading Day  following the Optional
Redemption Date.

            (b)  Failure by the Company to pay any portion of the Optional
Redemption Price on the 30th Trading Day  following an Optional Redemption
Date shall, at the option of the Holder subject thereto, result in the
invalidation ab initio of the unpaid portion of such optional redemption,
and, notwithstanding anything herein to the contrary, the Company shall
thereafter have no further rights to optionally redeem any shares of
Preferred Stock.  In such event, the Company shall, at the option of the
Holder, either, (i) not later than three Trading Days from receipt of
Holder's request for such election, return to the Holder all of the shares of
Preferred Stock for which such Optional Redemption Price has not been paid in
full (the "Unpaid Redemption Shares") or (ii) convert all or any portion of
the Unpaid Redemption Shares in which event the Per Share Market Value for
such shares shall be the lower of the Per Share Market Value calculated on
the date the Optional Redemption Price was originally due and the Per Share
Market Value as of the Holder's written demand for conversion. If the Holder
elects option (ii) above, the Company shall within three Trading Days of its
receipt of such election deliver to the Holder the shares of Common Stock

                                      A-12
<PAGE>   37

issuable upon conversion of the Unpaid Redemption Shares subject to such
Holder conversion demand and otherwise perform its obligations hereunder with
respect thereto.

            Section 7.  Redemption Upon Triggering  Events.

            (a)   Upon the occurrence of a Triggering  Event, each Holder
shall (in addition to all other rights it may have hereunder or under
applicable law), have the right, exercisable at the sole option of such
Holder, to require the Company to redeem all or a portion of the Preferred
Stock and such shares of Common Stock as described below then held by such
Holder for a redemption price, in cash, equal to the sum of (i) the Mandatory
Redemption Amount plus (ii) the product of (A) the number of Underlying
Shares issued in respect of conversions of shares of Preferred Stock
hereunder within thirty Trading Days of the Holder's demand for redemption
pursuant to this Section 6, and then held by the Holder and (B) the Closing
Price on the date such redemption is demanded or the date the redemption
price hereunder is paid in full, whichever is greater (such sum, the
"Redemption Price").  The Redemption Price shall be due and payable within
five Trading Days of the date on which the notice for the payment therefor is
provided by a Holder.   If the Company fails to pay the Redemption Price
hereunder in full pursuant to this Section on the date such amount is due in
accordance with this Section, the Company will pay interest thereon at a rate
of 18% per annum (or the lesser amount permitted by applicable law), accruing
daily from such date until the Redemption Price, plus all such interest
thereon, is paid in full.  For purposes of this Section, a share of Preferred
Stock is outstanding until such date as the Holder shall have received
Underlying Shares upon a conversion (or attempted conversion) thereof that
meets the requirements hereof.

            A "Triggering  Event" means any one or more of the following
events (whatever the reason and whether it shall be voluntary or involuntary
or effected by operation of law or pursuant to any judgment, decree or order
of any court, or any order, rule or regulation of any administrative or
governmental body):

                  (i)   the failure of an Underlying Shares Registration
Statement to be declared effective by the Commission on or prior to the 180th
day after the Original Issue Date;

                  (ii)  if, during the Effectiveness Period, the
effectiveness of the Underlying Shares Registration Statement lapses for any
reason for more than an aggregate of twenty Trading Days (which need not be
consecutive Trading Days), or the Holder shall not be permitted to resell
Registrable Securities under the Underlying Shares Registration Statement for
more than an aggregate of twenty Trading Days (which need not be consecutive
Trading Days);

                  (iii) the Company shall fail for any reason to deliver
certificates representing Underlying Shares issuable upon a conversion
hereunder that comply with the provisions hereof prior to the tenth Trading
Days after the Conversion Date or the Company shall provide notice to any
Holder, including by way of public announcement, at any time, of its
intention not to comply with requests for conversion of any shares of
Preferred Stock in accordance with the terms hereof;

                                      A-13
<PAGE>   38

                  (iv)  the Company shall be a party to any Change of Control
Transaction, shall agree to sell (in one or a series of related transactions)
more than 33% of its assets or shall redeem more than a de minimis number of
Common Stock or other Junior Securities (other than redemptions of Underlying
Shares);

                  (v)   an Event (as defined in the Registration Rights
Agreement) shall not have been cured to the satisfaction of the Holders prior
to the expiration of 60 days from the Event Date (as defined in the
Registration Rights Agreement) relating thereto (other than an Event
resulting from a failure of an Underlying Shares Registration Statement to be
declared effective by the Commission on or prior to the 180th day after the
Original Issue Date, which shall be covered by Section 6(a)(i));

                  (vi)   the Company shall fail for any reason to pay in full
the amount of cash due pursuant to a Buy-In within twenty-one days after
notice therefor is delivered hereunder or shall fail to pay all amounts owed
on account of an Event within twenty-one days of the date due;

                  (vii) the Company shall fail to have available a sufficient
number of authorized and unreserved shares of Common Stock to issue to such
Holder upon a conversion hereunder; or

                  (viii)   the Company shall fail to observe or perform any
other covenant, agreement or warranty contained in, or otherwise commit any
breach of the Transaction Documents (as defined in Section 8) that may result
in a Material Adverse Effect (as defined in the Purchase Agreement), and such
failure or breach shall not, if subject to the possibility of a cure by the
Company, have been remedied within ten Business Days after the date on which
written notice of such failure or breach shall have been given.

            Section 8.  Definitions.  For the purposes hereof, the following
terms shall have the following meanings:

            "Change of Control Transaction" means the occurrence of any of
(i) an acquisition after the date hereof by an individual or legal entity or
"group" (as described in Rule 13d-5(b)(1) promulgated under the Exchange Act)
of effective control (whether through legal or beneficial ownership of
capital stock of the Company, by contract or otherwise) of in excess of 40%

Closing Date.

                  (c) If (a) a Registration Statement is not filed on or prior
to its Filing Date (if the Company files such Registration Statement without
affording the Holder the opportunity to review and comment on the same as
required by Section 3(a) hereof, the Company shall not be deemed to have
satisfied this clause (a)), or (b) the Company fails to file or make with the
Commission an acceleration request in accordance with Rule 461 promulgated under

Registrable Securities to which it is required to relate at any time prior to
the expiration of the Effectiveness Period without being succeeded within ten
Business Days by an amendment to such Registration Statement or by a subsequent
Registration Statement filed with and declared effective by the Commission, or
(e) the Common Stock shall be delisted or suspended from trading on the Nasdaq
National Market ("NASDAQ"), the New York Stock Exchange, the American Stock
Exchange or the Nasdaq Smallcap Market (each, a "Subsequent Market") for more
than three

                                      B-4
<PAGE>   48

Trading Days (which need not be consecutive Trading Days), or (f) the conversion
or exercise rights of the Holders pursuant to Certificate of Designation and the
Warrants are suspended for any reason, (any such failure or breach being
referred to as an "Event," and for purposes of clauses (a), (c), (f) the date on
which such Event occurs, or for purposes of clause (b) the date on which such
five Business Day period is exceeded, or for purposes of clause (d) the date
which such ten Business Day-period is exceeded, or for purposes of clause (e)
the date on which such three Trading Day-period is exceeded, being referred to
as "Event Date"), then, on each such Event Date and every monthly anniversary
thereof until the applicable Event is cured, the Company shall pay to each
Holder an amount in cash, as liquidated damages and not as a penalty, equal to
2.0% of the purchase price paid by such Holder pursuant to the Purchase
Agreement. If the Company fails to pay any liquidated damages pursuant to this
Section in full within seven days after the date payable, the Company will pay
interest thereon at a rate of 18% per annum (or such lesser maximum amount that
is permitted to be paid by applicable law) to the Holder, accruing daily from
the date such liquidated damages are due until such amounts, plus all such
interest thereon, are paid in full. The liquidated damages pursuant to the terms
hereof shall apply on a pro-rata basis for any portion of a month prior to the
cure of an Event.

                  (d) For a period not exceeding either (i) 10 consecutive
Trading Days or (ii) an aggregate of 25 Trading Days in any 12 month period, the
Company may suspend the ability of the Holders to make dispositions under a
Registration Statement or Prospectus by providing the Holders with written
notification (a "Blocking Notice") if the Company's board of directors
determines in its good faith judgment that the Company's obligation to ensure
that such Registration Statement and Prospectus contain current and complete
information would require the Company to make a public disclosure regarding a
material non-public transaction, provided, that the Company shall not be
entitled to deliver a Blocking Notice within 10 Trading Days of the expiration
of any Blocking Notice previously delivered. Each Blocking Notice shall contain
a general statement of the reasons for such postponement and an approximation of
the anticipated delay. Notwithstanding anything to the contrary herein, in the
event of a merger of the Company with or into another entity that is not
wholly-owned by the Company and is reportable under Item 2 of Form 8-K under the
Exchange Act, the Company may deliver a Blocking Notice for a period of up to 25
consecutive Trading Days in any 12 month period, in which case, the number of
consecutive Trading Days available to the Company pursuant to clause (ii) of
this Section shall be reduced by such number of Trading Days. Each Holder agrees
by acquisition of the Registrable Securities that, upon receipt of a Blocking
Notice from the Company, such Holder shall not dispose of, sell or offer for
sale the Registrable Securities pursuant to the Registration Statement until
such Holder receives (i) copies of the supplemented or amended Prospectus, or
until counsel for the Company shall have determined that such disclosure is not
required due to subsequent events, (ii) notice in writing from the Company that
the use of the Prospectus may be resumed and (iii) copies of any additional or
supplemental filings that are incorporated by reference to in the Prospectus. In
the event the Company shall provide any Blocking Notice pursuant to this
Section, the Effectiveness Date and the Effectiveness Period shall be extended
for a number of days equal to the number of days during which such Blocking
Notice is in effect.

                  (e) Each Holder of Registrable Securities agrees to furnish to
the Company with

                                      B-5
<PAGE>   49

its name, number of shares now owned and offered in the Registration Statement,
its address, the name of the natural person who controls the disposition and
investment of the registered securities and changes to the Plan of Distribution.
Without limiting the foregoing, the Company may exclude a Holder's Registrable
securities from any Registration Statement, or suspend the preparation of a
Registration Statement, if such Holder has not furnished to the Company in
writing the information with respect to such Holder and its intended plan of
distribution set forth in the first sentence of this paragraph. However, the
Company shall (i) promptly include in such Registration Statement the
Registrable Securities of any such Holder who subsequently provides such
information, and (ii) file the Registration Statement or an appropriate
amendment thereto on or prior to the date that is ten days after the Company
receives such information. Each Holder agrees to notify the Company as promptly
as practicable of any inaccuracy or change in information previously furnished
by such Holder to the Company and to promptly furnish to the Company any
additional information required to correct and update any previously furnished
information or required so that such Prospectus shall not contain, with respect
to such Holder or the distribution of such Holder's Registrable Securities, an
untrue statement of a material fact or omit to state a material fact required to
be stated therein or necessary to make the statements therein not misleading in
light of the circumstances then existing.

         3.       Registration Procedures

                  In connection with the Company's registration obligations
hereunder, the Company shall:

                  (a) Not less than five Business Days prior to the filing of
each Registration Statement or any related Prospectus or any amendment or
supplement thereto (including any document that would be incorporated or deemed
to be incorporated therein by reference), the Company shall, (i) furnish to the
Holders and their Special Counsel copies of all such documents proposed to be
filed, which documents (other than those incorporated or deemed to be
incorporated by reference) will be subject to the review of such Holders and
their Special Counsel, and (ii) cause its officers and directors, counsel and
independent certified public accountants to respond to such inquiries as shall
be necessary, in the reasonable opinion of Special Counsel to conduct a
reasonable investigation within the meaning of the Securities Act. The Company
shall not file the Registration Statement or any such Prospectus or any
amendments or supplements thereto to which the Holders of a majority of the
Registrable Securities and their Special Counsel shall reasonably object,
provided, the Company is notified of such objection no later than 3 Business
Days after the Holders have been so furnished copies of such documents.

                  (b) (i) Prepare and file with the Commission such amendments,
including post-effective amendments, to the Registration Statement and the
Prospectus used in connection therewith as may be necessary to keep the
Registration Statement continuously effective as to the applicable Registrable
Securities for the Effectiveness Period; (ii) cause the related Prospectus to be
amended or supplemented by any required Prospectus supplement, and as so
supplemented or amended to be filed pursuant to Rule 424, if required thereby;
(iii) respond as promptly as reasonably possible, and in any event within ten
Business Days, to any comments received from the Commission with respect to the
Registration Statement or any amendment thereto and as promptly as reasonably
possible provide the Holders true and complete copies of all correspondence from
and

                                      B-6
<PAGE>   50

to the Commission relating to the Registration Statement; and (iv) comply in
all material respects with the provisions of the Securities Act and the Exchange
Act with respect to the disposition of all Registrable Securities covered by the
Registration Statement during the applicable period in accordance with the
intended methods of disposition by the Holders thereof set forth in the
Registration Statement as so amended or in such Prospectus as so supplemented.

                  (c) File additional Registration Statements upon the Company's
receipt of notice from the Holders that the number of Registrable Securities
exceeds 85% of the number of shares of Common Stock then registered for the
account of the Holders in all existing Registration Statements hereunder.

                  (d) Notify the Holders of Registrable Securities to be sold
and their Special Counsel as promptly as reasonably possible (and, in the case
of (i)(A) below, not less than five Business Days prior to such filing) and (if
requested by any such Person) confirm such notice in writing no later than one
Business Day following the day (i)(A) when a Prospectus or any Prospectus
supplement or post-effective amendment to the Registration Statement is proposed
to be filed; (B) when the Commission notifies the Company whether there will be
a "review" of such Registration Statement and whenever the Commission comments
in writing on such Registration Statement (the Company shall provide true and
complete copies thereof and all written responses thereto to each of the
Holders); and (C) with respect to the Registration Statement or any
post-effective amendment, when the same has become effective; (ii) of any
request by the Commission or any other Federal or state governmental authority
for amendments or supplements to the Registration Statement or Prospectus or for
additional information; (iii) of the issuance by the Commission of any stop
order suspending the effectiveness of the Registration Statement covering any or
all of the Registrable Securities or the initiation of any Proceedings for that
purpose; (iv) if at any time any of the representations and warranties of the
Company contained in any agreement contemplated hereby cease to be true and
correct in all material respects; (v) of the receipt by the Company of any
notification with respect to the suspension of the qualification or exemption
from qualification of any of the Registrable Securities for sale in any
jurisdiction, or the initiation or threatening of any Proceeding for such
purpose; and (vi) of the occurrence of any event or passage of time that makes
the financial statements included in the Registration Statement ineligible for
inclusion therein or any statement made in the Registration Statement or
Prospectus or any document incorporated or deemed to be incorporated therein by
reference untrue in any material respect or that requires any revisions to the
Registration Statement, Prospectus or other documents so that, in the case of
the Registration Statement or the Prospectus, as the case may be, it will not
contain any untrue statement of a material fact or omit to state any material
fact required to be stated therein or necessary to make the statements therein,
in light of the circumstances under which they were made, not misleading.

                  (e) Promptly deliver to each Holder and their Special Counsel,
without charge, as many copies of the Prospectus or Prospectuses (including each
form of prospectus) and each amendment or supplement thereto as such Persons may
reasonably request. Except as otherwise provided in Section 2(d) and Section
6(e) of this Agreement, the Company hereby consents to the use of such
Prospectus and each amendment or supplement thereto by each of the selling
Holders in connection with the offering and sale of the Registrable Securities
covered by such Prospectus and any amendment or supplement thereto.

                                      B-7
<PAGE>   51

                  (f) Prior to any public offering of Registrable Securities,
use its best efforts to register or qualify or cooperate with the selling
Holders and their Special Counsel in connection with the registration or
qualification (or exemption from such registration or qualification) of such
Registrable Securities for offer and sale under the securities or Blue Sky laws
of such jurisdictions within the United States as any Holder requests in
writing, to keep each such registration or qualification (or exemption
therefrom) effective during the Effectiveness Period and to do any and all other
acts or things necessary or advisable to enable the disposition in such
jurisdictions of the Registrable Securities covered by a Registration Statement;
provided, that the Company shall not be required to qualify generally to do
business or to qualify as a securities dealer in any jurisdiction where it is
not then so qualified or subject the Company to any material tax in any such
jurisdiction where it is not then so subject.

                  (g) Cooperate with the Holders to facilitate the timely
preparation and delivery of certificates representing Registrable Securities to
be delivered to a transferee pursuant to a Registration Statement, which
certificates shall be free, to the extent permitted by the Purchase Agreement,
of all restrictive legends, and to enable such Registrable Securities to be in
such denominations and registered in such names as any such Holders may request.

                  (h) Upon the occurrence of any event contemplated by Section
3(d)(vi), as promptly as reasonably possible, prepare a supplement or amendment,
including a post-effective amendment, to the Registration Statement or a
supplement to the related Prospectus or any document incorporated or deemed to
be incorporated therein by reference, and file any other required document so
that, as thereafter delivered, neither the Registration Statement nor such
Prospectus will contain an untrue statement of a material fact or omit to state
a material fact required to be stated therein or necessary to make the
statements therein, in light of the circumstances under which they were made,
not misleading.

                  (i) Comply with all applicable rules and regulations of the
Commission.

         4.       Registration Expenses. All fees and expenses incident to the
performance of or compliance with this Agreement by the Company shall be borne
by the Company whether or not any Registrable Securities are sold pursuant to
the Registration Statement. The fees and expenses referred to in the foregoing
sentence shall include, without limitation, (i) all registration and filing fees
(including, without limitation, fees and expenses (A) with respect to filings
required to be made with the NASDAQ and any Subsequent Market on which the
Common Stock is then listed for trading, and (B) in compliance with applicable
state securities or Blue Sky laws (including, without limitation, fees and
disbursements of counsel for the Company in connection with Blue Sky
qualifications or exemptions of the Registrable Securities and determination of
the eligibility of the Registrable Securities for investment under the laws of
such jurisdictions as requested by the Holders )), (ii) printing or photocopying
expenses (including, without limitation, expenses of printing certificates for
Registrable Securities and of printing or photocopying prospectuses requested by
the Holders), (iii) messenger, telephone and delivery expenses, (iv) fees and
disbursements of counsel for the Company, (v) fees and disbursements of Special
Counsel for the Holders in an amount not to exceed $7,500 and (vi) fees and

         5.       Indemnification

                  (a) Indemnification by the Company. The Company shall,
notwithstanding any termination of this Agreement, indemnify and hold harmless
each Holder, the officers, directors, agents, brokers (including brokers who
offer and sell Registrable Securities as principal as a result of a pledge or
any failure to perform under a margin call of Common Stock), investment advisors
and employees of each of them, each Person who controls any such Holder (within
the meaning of Section 15 of the Securities Act or Section 20 of the Exchange
Act) and the officers, directors, agents and employees of each such controlling
Person, to the fullest extent permitted by applicable law, from and against any
and all losses, claims, damages, liabilities, costs (including, without
limitation, costs of preparation and attorneys' fees) and expenses
(collectively, "Losses"), as incurred, arising out of or relating to any untrue
or alleged untrue statement of a material fact contained in the Registration
Statement, any Prospectus or any form of prospectus or in any amendment or
supplement thereto or in any preliminary prospectus, or arising out of or
relating to any omission or alleged omission of a material fact required to be
stated therein or necessary to make the statements therein (in the case of any
Prospectus or form of prospectus or supplement thereto, in light of the
circumstances under which they were made) not misleading, except to the extent,
but only to the extent, that (1) such untrue statements or omissions are based
solely upon information regarding such Holder furnished in writing to the
Company by such Holder expressly for use therein, or to the extent that such
information relates to such Holder or such Holder's proposed method of
distribution of Registrable Securities and was reviewed and expressly approved
in writing by such Holder expressly for use in the Registration Statement, such
Prospectus or such form of Prospectus or in any amendment or supplement thereto
or (2) in the case of an occurrence of an event of the type specified in Section
3(d)(ii)-(vi), the use by such Holder of an outdated or defective Prospectus
after the Company has notified such Holder in writing that the Prospectus is
outdated or defective and prior to the receipt by such Holder of the Advice
contemplated in Section 6(e). The Company shall notify the Holders promptly of
the institution, threat or assertion of any Proceeding of which the Company is
aware in connection with the transactions contemplated by this Agreement.

                  (b) Indemnification by Holders. Each Holder shall, severally
and not jointly, indemnify and hold harmless the Company, its directors,
officers, agents and employees, each Person who controls the Company (within the
meaning of Section 15 of the Securities Act and Section 20 of the Exchange Act),
and the directors, officers, agents or employees of such controlling Persons, to
the fullest extent permitted by applicable law, from and against all Losses (as
determined by a court of competent jurisdiction in a final judgment not subject
to appeal or review) arising solely out of or based solely upon any untrue
statement of a material fact contained in any Registration Statement, any
Prospectus, or any form of prospectus, or in any amendment or supplement
thereto, or arising solely out of or based solely upon any omission of a
material fact required to be stated therein or necessary to make the statements
therein not misleading to the extent, but only to the extent, that such untrue
statement or omission is contained in any information so furnished in writing by
such Holder to the Company specifically for inclusion in such Registration
Statement or such Prospectus or to the extent that (1) such untrue statements or
omissions are based solely upon information regarding such Holder furnished in
writing to the Company by such Holder expressly for use therein, or to the
extent that such information relates to such Holder or such Holder's pro-

                                      B-9
<PAGE>   53

posed method of distribution of Registrable Securities and was reviewed and
expressly approved in writing by such Holder expressly for use in the
Registration Statement, such Prospectus or such form of Prospectus or in any
amendment or supplement thereto or (2) in the case of an occurrence of an event
of the type specified in Section 3(d)(ii)-(vi), the use by such Holder of an
outdated or defective Prospectus after the Company has notified such Holder in
writing that the Prospectus is outdated or defective and prior to the receipt by
such Holder of the Advice contemplated in Section 6(e). In no event shall the
liability of any selling Holder hereunder be greater in amount than the dollar
amount of the net proceeds received by such Holder upon the sale of the
Registrable Securities giving rise to such indemnification obligation.

                  (c) Conduct of Indemnification Proceedings. If any Proceeding
shall be brought or asserted against any Person entitled to indemnity hereunder
(an "Indemnified Party"), such Indemnified Party shall promptly notify the
Person from whom indemnity is sought (the "Indemnifying Party") in writing, and
the Indemnifying Party shall assume the defense thereof, including the
employment of counsel reasonably satisfactory to the Indemnified Party and the
payment of all fees and expenses incurred in connection with defense thereof;
provided, that the failure of any Indemnified Party to give such notice shall
not relieve the Indemnifying Party of its obligations or liabilities pursuant to
this Agreement, except (and only) to the extent that it shall be finally
determined by a court of competent jurisdiction (which determination is not
subject to appeal or further review) that such failure shall have proximately
and materially adversely prejudiced the Indemnifying Party.

                  An Indemnified Party shall have the right to employ separate
counsel in any such Proceeding and to participate in the defense thereof, but
the fees and expenses of such counsel shall be at the expense of such
Indemnified Party or Parties unless: (1) the Indemnifying Party has agreed in
writing to pay such fees and expenses; or (2) the Indemnifying Party shall have
failed promptly to assume the defense of such Proceeding and to employ counsel
reasonably satisfactory to such Indemnified Party in any such Proceeding; or (3)
the named parties to any such Proceeding (including any impleaded parties)
include both such Indemnified Party and the Indemnifying Party, and such
Indemnified Party shall have been advised by counsel that a conflict of interest
is likely to exist if the same counsel were to represent such Indemnified Party
and the Indemnifying Party (in which case, if such Indemnified Party notifies
the Indemnifying Party in writing that it elects to employ separate counsel at
the expense of the Indemnifying Party, the Indemnifying Party shall not have the
right to assume the defense thereof and such counsel shall be at the expense of
the Indemnifying Party). The Indemnifying Party shall not be liable for any
settlement of any such Proceeding effected without its written consent, which
consent shall not be unreasonably withheld. No Indemnifying Party shall, without
the prior written consent of the Indemnified Party, effect any settlement of any
pending Proceeding in respect of which any Indemnified Party is a party, unless
such settlement includes an unconditional release of such Indemnified Party from
all liability on claims that are the subject matter of such Proceeding.

                  All fees and expenses of the Indemnified Party (including
reasonable fees and expenses to the extent incurred in connection with
investigating or preparing to defend such Proceeding in a manner not
inconsistent with this Section) shall be paid to the Indemnified Party, as
incurred, within ten Business Days of written notice thereof to the Indemnifying
Party (regardless

                                      B-10
<PAGE>   54

of whether it is ultimately determined that an Indemnified Party is not
entitled to indemnification hereunder; provided, that the Indemnifying Party
may require such Indemnified Party to undertake to reimburse promptly all such
fees and expenses to the extent it is finally judicially determined that such
Indemnified Party is not entitled to indemnification hereunder).

                  (d) Contribution. If a claim for indemnification under Section
5(a) or 5(b) is unavailable to an Indemnified Party (by reason of public policy
or otherwise), then each Indemnifying Party, in lieu of indemnifying such
Indemnified Party, shall contribute to the amount paid or payable by such
Indemnified Party as a result of such Losses, in such proportion as is
appropriate to reflect the relative fault of the Indemnifying Party and
Indemnified Party in connection with the actions, statements or omissions that
resulted in such Losses as well as any other relevant equitable considerations.
The relative fault of such Indemnifying Party and Indemnified Party shall be
determined by reference to, among other things, whether any action in question,
including any untrue or alleged untrue statement of a material fact or omission
or alleged omission of a material fact, has been taken or made by, or relates to
information supplied by, such Indemnifying Party or Indemnified Party, and the
parties' relative intent, knowledge, access to information and opportunity to
correct or prevent such action, statement or omission. The amount paid or
payable by a party as a result of any Losses shall be deemed to include, subject
to the limitations set forth in Section 5(c), any reasonable attorneys' or other
reasonable fees or expenses incurred by such party in connection with any
Proceeding to the extent such party would have been indemnified for such fees or
expenses if the indemnification provided for in this Section was available to
such party in accordance with its terms.

                  The parties hereto agree that it would not be just and
equitable if contribution pursuant to this Section 5(d) were determined by pro
rata allocation or by any other method of allocation that does not take into
account the equitable considerations referred to in the immediately preceding
paragraph. Notwithstanding the provisions of this Section 5(d), no Holder shall
be required to contribute, in the aggregate, any amount in excess of the amount
by which the proceeds actually received by such Holder from the sale of the
Registrable Securities subject to the Proceeding exceeds the amount of any
damages that such Holder has otherwise been required to pay by reason of such
untrue or alleged untrue statement or omission or alleged omission.

                  The indemnity and contribution agreements contained in this
Section are in addition to any liability that the Indemnifying Parties may have
to the Indemnified Parties.

         6.       Miscellaneous

                  (a) Amendments and Waivers. The provisions of this Agreement,
including the provisions of this sentence, may not be amended, modified or
supplemented, and waivers or consents to departures from the provisions hereof
may not be given, unless the same shall be in writing and signed by the Company
and the Holders of at least two-thirds of the then outstanding Registrable
Securities. Notwithstanding the foregoing, a waiver or consent to depart from
the provisions hereof with respect to a matter that relates exclusively to the
rights of Holders and that does not directly or indirectly affect the rights of
other Holders may be given by Holders of at least a majority of the outstanding
Registrable Securities to which such waiver or consent relates; provided,
however, that the provisions of this sentence may not be amended, modified, or
supplemented except in accordance with the provisions of the immediately
preceding sentence.

                  (b) No Inconsistent Agreements. Neither the Company nor any of
its subsidiaries has entered, as of the date hereof, nor shall the Company or
any of its subsidiaries, on or after the date of this Agreement, enter into any
agreement with respect to its securities, that would have the effect of
impairing the rights granted to the Holders in this Agreement or otherwise
conflict with the provisions hereof. Except as and to the extent specified in
Schedule 6(b) hereto, neither the Company nor any of its subsidiaries has
previously entered into any agreement granting any registration rights with
respect to any of its securities to any Person that have not been satisfied in
full.

                  (c) No Piggyback on Registrations. Except as and to the extent
specified in Schedule 6(b) hereto, neither the Company nor any of its security
holders (other than the Holders in such capacity pursuant hereto) may include
securities of the Company in the Registration Statement other than the
Registrable Securities, and the Company shall not after the date hereof enter
into any agreement providing any such right to any of its security holders.

                  (d) Compliance. Each Holder covenants and agrees that it will
comply with the prospectus delivery requirements of the Securities Act as
applicable to it in connection with sales of Registrable Securities pursuant to
the Registration Statement.

                  (e) Discontinued Disposition. Each Holder agrees by its
acquisition of such Registrable Securities that, upon receipt of a notice from
the Company of the occurrence of any event of the kind described in Sections
3(d)(ii), 3(d)(iii), 3(d)(iv), 3(d)(v) or 3(d)(vi), such Holder will forthwith
discontinue disposition of such Registrable Securities under the Registration
Statement until such Holder's receipt of the copies of the supplemented
Prospectus and/or amended Registration Statement contemplated by Section 3(h),
or until it is advised in writing (the "Advice") by the Company that the use of
the applicable Prospectus may be resumed, and, in either case, has received
copies of any additional or supplemental filings that are incorporated or deemed
to be incorporated by reference in such Prospectus or Registration Statement.
The Company may provide appropriate stop orders to enforce the provisions of
this paragraph.

                  (f) Piggy-Back Registrations. If at any time during the
Effectiveness Period there is not an effective Registration Statement covering
all of the Registrable Securities and the

                                      B-12
<PAGE>   56

Company shall determine to prepare and file with the Commission a registration
statement relating to an offering for its own account or the account of others
under the Securities Act of any of its equity securities, other than on Form S-4
or Form S-8 (each as promulgated under the Securities Act) or their then
equivalents relating to equity securities to be issued solely in connection with
any acquisition of any entity or business or equity securities issuable in
connection with stock option or other employee benefit plans, then the Company
shall send to each Holder written notice of such determination and, if within
fifteen days after receipt of such notice, any such Holder shall so request in
writing, the Company shall include in such registration statement all or any
part of such unregistered Registrable Securities such holder requests to be
registered. In the case of a registration statement for an underwritten public
offering by the Company (which shall not include a equity line of credit or
similar financing), the right of any Holder to registration pursuant to this
Section 6(f) shall be conditioned upon the inclusion of such Holders'
Registrable Securities in the underwriting to the extent provided herein. All
Holders proposing to distribute their Registrable Securities through such
underwriting shall (together with the Company and other shareholders
distributing their securities through such underwriting) enter into an
underwriting agreement in customary form with the underwriter(s) selected for
such underwriting by the Company. Notwithstanding any other provision of this
Section 6(f), if the underwriter(s) determine(s) that marketing factors require
limitation of the number of the number of shares of Common Stock to be
underwritten, the underwriter(s) may limit the number of Registrable Securities
to be included in the registration and the underwriting; provided, that (i) all
other selling shareholders participating in such registration and underwriting
shall be limited pro-rata and (ii) the underwriter may not limit the amount of
Registrable Securities included in such registration and underwriting to less
than an amount equal to 10% of the amount of all the shares of Common Stock
included within such registration and underwriting. The Company shall so advise
all Holders which would otherwise be registered and underwritten pursuant
hereto, and the number of Registrable Securities that may be included in the in
the registration and underwriting shall be allocated among all Holders and other
shareholders distributing their securities through such underwriting thereof in
proportion, as nearly as practicable, to the respective amounts of Registrable
Securities and other securities (as applicable) entitled to inclusion in such
registration held by such Holders at the time of filing of the registration
statement. If any Holder disapproves of the terms of terms of any such
underwriting, he may elect to withdraw therefrom and from the registration by
written notice to the Company.

                  (g) Notices. Any and all notices or other communications or
deliveries required or permitted to be provided hereunder shall be in writing
and shall be deemed given and effective on the earliest of (i) the date of
transmission, if such notice or communication is delivered via facsimile at the
facsimile telephone number specified in this Section prior to 6:30 p.m. (New
York City time) on a Business Day, (ii) the Business Day after the date of
transmission, if such notice or communication is delivered via facsimile at the
facsimile telephone number specified in this Agreement later than 6:30 p.m. (New
York City time) on any date and earlier than 11:59 p.m. (New York City time) on
such date, (iii) the Business Day following the date of mailing, if sent by
nationally recognized overnight courier service, or (iv) upon actual receipt by
the party to whom such notice is required to be given. The address for such
notices and communications shall be as follows:

manner, by such Person.

                  (h) Successors and Assigns. This Agreement shall inure to the
benefit of and be binding upon the successors and permitted assigns of each of
the parties and shall inure to the benefit of each Holder. The Company may not
assign its rights or obligations hereunder without the prior written consent of
each Holder. Each Holder may assign its rights hereunder in the manner and to
the Persons as permitted under Sections 4.6 and 3.1(a) of the Purchase
Agreement.

                  (i) Counterparts. This Agreement may be executed in any number
of counterparts, each of which when so executed shall be deemed to be an
original and, all of which taken together shall constitute one and the same
Agreement. In the event that any signature is delivered by facsimile
transmission, such signature shall create a valid binding obligation of the
party executing (or on whose behalf such signature is executed) the same with
the same force and effect as if such facsimile signature were the original
thereof.

                  (j) Governing Law. All questions concerning the construction,
validity, enforcement and interpretation of this Agreement shall be governed by
and construed and enforced in accordance with the internal laws of the State of
New York, without regard to the principles of conflicts of law thereof. Each
party hereby irrevocably submits to the exclusive jurisdiction of the state and
federal courts sitting in the City of New York, borough of Manhattan, for the
adjudication of any dispute hereunder or in connection herewith or with any
transaction contemplated hereby or discussed herein, and hereby irrevocably
waives, and agrees not to assert in any suit, action or proceeding, any claim
that it is not personally subject to the jurisdiction of any such court, or that
such suit, action or proceeding is improper. Each party hereby irrevocably
waives personal service of process and consents to process being served in any
such suit, action or proceeding by mailing a copy thereof to such party at the
address in effect for notices to it under this Agreement and agrees

                                      B-14

that such service shall constitute good and sufficient service of process and
notice thereof. Nothing contained herein shall be deemed to limit in any way any
right to serve process in any manner permitted by law.

                  (k) Cumulative Remedies.  The remedies provided herein are
cumulative and not exclusive of any remedies provided by law.

                  (l) Severability. If any term, provision, covenant or
restriction of this Agreement is held by a court of competent jurisdiction to be
invalid, illegal, void or unenforceable, the remainder of the terms, provisions,
covenants and restrictions set forth herein shall remain in full force and
effect and shall in no way be affected, impaired or invalidated, and the parties
hereto shall use their reasonable efforts to find and employ an alternative
means to achieve the same or substantially the same result as that contemplated
by such term, provision, covenant or restriction. It is hereby stipulated and
declared to be the intention of the parties that they would have executed the
remaining terms, provisions, covenants and restrictions without including any of
such that may be hereafter declared invalid, illegal, void or unenforceable.

                  (m) Headings.  The headings in this Agreement are for
convenience of reference only and shall not limit or otherwise affect the
meaning hereof.

                  (n) Independent Nature of Holders' Obligations and Rights. The
obligations of each Holder hereunder is several and not joint with the
obligations of any other Holder hereunder, and no Holder shall be responsible in
any way for the performance of the obligations of any other Holder hereunder.
Nothing contained herein or in any other agreement or document delivered at any
closing, and no action taken by any Holder pursuant hereto or thereto, shall be
deemed to constitute the Holders as a partnership, an association, a joint
venture or any other kind of entity, or create a presumption that the Holders
are in any way acting in concert with respect to such obligations or the
transactions contemplated by this Agreement. Each Holder shall be entitled to
protect and enforce its rights, including without limitation the rights arising
out of this Agreement, and it shall not be necessary for any other Holder to be
joined as an additional party in any proceeding for such purpose.

                              PLAN OF DISTRIBUTION

         The Selling Stockholders and any of their pledgees, assignees and
successors-in-interest may, from time to time, sell any or all of their shares
of Common Stock on any stock exchange, market or trading facility on which the
shares are traded or in private transactions. These sales may be at fixed or
negotiated prices. The Company will receive no part of the proceeds from the
sale of the Shares by the Selling Stockholders. The Selling Stockholders may use
any one or more of the following methods when selling shares:

-        ordinary brokerage transactions and transactions in which the broker-
         dealer solicits purchasers;

-        block trades in which the broker-dealer will attempt to sell the shares
         as agent but may position and resell a portion of the block as
         principal to facilitate the transaction;

-        purchases by a broker-dealer as principal and resale by the broker-
         dealer for its account;

-        an exchange distribution or special offering in accordance with the
         rules of the applicable exchange;

-        privately negotiated transactions;

-        short sales;

-        sales by broker-dealers of a specified number of such shares at a
         stipulated price per share;

-        a combination of any such methods of sale; and

-        any other method permitted pursuant to applicable law.

         The Selling Stockholders may also sell shares under Rule 144 under the
Securities Act, if available, rather than under this prospectus.

         The Selling Stockholders may also engage in short sales against the
box, puts and calls and other transactions in securities of the Company or
derivatives of Company securities and may sell or deliver shares in connection
with these trades. The Selling Stockholders may pledge their shares to their
brokers under the margin provisions of customer agreements. If a Selling
Stockholder defaults on a margin loan, the broker may, from time to time, offer
and sell the pledged shares. The Selling Stockholders have advised the Company
that they have not entered into any agreements, understandings or arrangements
with any underwriters or broker-dealers regarding the sale of their shares other
than ordinary course brokerage arrangements, nor is there an underwriter or

                                      B-19
<PAGE>   63

coordinating broker acting in connection with the proposed sale of shares by the
Selling Stockholders.

         Broker-dealers engaged by the Selling Stockholders may arrange for
other brokers-dealers to participate in sales. Broker-dealers may receive
commissions or discounts from the Selling Stockholders (or, if any broker-dealer
acts as agent for the purchaser of shares, from the purchaser) in amounts to be
negotiated. The Selling Stockholders do not expect these commissions and
discounts to exceed what is customary in the types of transactions involved.

         The Selling Stockholders and any broker-dealers or agents that are
involved in selling the shares may be deemed to be "underwriters" within the
meaning of the Securities Act in connection with such sales. In such event, any
commissions received by such broker-dealers or agents and any profit on the
resale of the shares purchased by them may be deemed to be underwriting
commissions or discounts under the Securities Act.

         The Company is required to pay all fees and expenses incident to the
registration of the shares, including fees and disbursements of counsel to the
Selling Stockholders. The Company has agreed to indemnify the Selling
Stockholders against certain losses, claims, damages and liabilities, including
liabilities under the Securities Act.

         If any Selling Stockholder notifies the Company that the Selling
Stockholder has entered into any material arrangement with a broker-dealer for
the sale of shares through a block trade, special offering, exchange
distribution or secondary distribution or a purchase by a broker or dealer, the
Company will file a supplement to this prospectus, if required, pursuant to Rule
424(b) under the Securities Act, disclosing:

-        the name of the participating broker-dealer(s);

-        the number of shares involved;

-        the price at which such shares were sold;

-        the commission paid or discounts or concessions allowed to the broker-
         dealer(s), where applicable;

-        whether the broker-dealer(s) conducted any investigations to verify the
         information in or incorporated by reference in this prospectus; and

-        other material facts of the transaction.

         Also, if a Selling Stockholder notifies the Company that a donee,
pledgee, transferee, or other successor-in-interest of the shares intends to
sell more than 500 shares, the Company will file an appropriate supplement to
this prospectus.

NEITHER THESE SECURITIES NOR THE SECURITIES INTO WHICH THESE SECURITIES ARE
EXERCISABLE HAVE BEEN REGISTERED WITH THE SECURITIES AND EXCHANGE COMMISSION OR
THE SECURITIES COMMISSION OF ANY STATE IN RELIANCE UPON AN EXEMPTION FROM
REGISTRATION UNDER SECURITIES ACT OF 1933, AS AMENDED (THE "SECURITIES ACT"),

                                 SERANOVA, INC.

                                     WARRANT

Warrant No.[ ]                                        Dated: September [ ], 2000

         SeraNova, Inc., a New Jersey corporation (the "Company"), hereby
certifies that, for value received, [ ] or its registered assigns ("Holder"), is
entitled, subject to the terms set forth below, to purchase from the Company up
to a total of [150,000] shares of common stock, $.01 par value per share (the
"Common Stock"), of the Company (each such share, a "Warrant Share" and all such
shares, the "Warrant Shares") at the Exercise Price set forth in Section 3, at
any time and from time to time from and after the date hereof and through and
including September [ ], 2005 (the "Expiration Date"), and subject to the
following terms and conditions:

         1.       Registration of Warrant. The Company shall register this
Warrant, upon records to be maintained by the Company for that purpose (the
"Warrant Register"), in the name of the record Holder hereof from time to time.
The Company may deem and treat the registered Holder of this Warrant as the
absolute owner hereof for the purpose of any exercise hereof or any distribution
to the Holder, and for all other purposes, and the Company shall not be affected
by notice to the contrary.

                                     D-1-1
<PAGE>   65

         2.       Registration of Transfers and Exchanges.

                  (a) The Company shall register the transfer of any  portion of
this Warrant in the Warrant Register, upon surrender of this Warrant, with the
Form of Assignment attached hereto duly completed and signed, to the Transfer
Agent or to the Company at its address for notice set forth in Section 12. Upon
any such registration or transfer, a new warrant to purchase Common Stock, in
substantially the form of this Warrant (any such new warrant, a "New Warrant"),
evidencing the portion of this Warrant so transferred shall be issued to the
transferee and a New Warrant evidencing the remaining portion of this Warrant
not so transferred, if any, shall be issued to the transferring Holder. The
acceptance of the New Warrant by the transferee thereof shall be deemed the
acceptance of such transferee of all of the rights and obligations of a holder
of a Warrant.

                  (b) This Warrant is exchangeable, upon the surrender hereof by
the Holder to the office of the Company at its address for notice set forth in
Section 12 for one or more New Warrants, evidencing in the aggregate the right
to purchase the number of Warrant Shares which may then be purchased hereunder.
Any such New Warrant will be dated the date of such exchange.

         3.       Duration and Exercise of Warrants.

                  (a) This Warrant shall be exercisable by the registered Holder
on any business day before 6:30 P.M., New York City time, at any time and from
time to time on or after the date hereof to and including the Expiration Date.
At 6:30 P.M., New York City time on the Expiration Date, the portion of this
Warrant not exercised prior thereto shall be and become void and of no value.
Prior to the Expiration Date, the Company may not call or otherwise redeem this
Warrant.

                  (b) Upon delivery of a duly completed and signed Form of
Election to Purchase attached hereto (and the grid attached hereto as Annex A)
duly completed and signed, to the Company at its address for notice set forth in
Section 12 and upon payment of the Exercise Price multiplied by the number of
Warrant Shares that the Holder intends to purchase hereunder, in the manner
provided hereunder, all as specified by the Holder in the Form of Election to
Purchase, the Company shall promptly (but in no event later than 3 business days
after the Date of Exercise (as defined herein)) issue or cause to be issued and
cause to be delivered to or upon the written order of the Holder and in such
name or names as the Holder may designate, a certificate for the Warrant Shares
issuable upon such exercise, free of restrictive legends except (i) either in
the event that a registration statement covering the resale of the Warrant
Shares and naming the Holder as a selling stockholder thereunder is not then
effective or the Warrant Shares are not freely transferable without volume
restrictions pursuant to Rule 144(k) promulgated under the Securities Act of
1933, as amended (the "Securities Act"), or (ii) if this Warrant shall have been
issued pursuant to a written agreement between the original Holder and the
Company, as required by such agreement. Any person so designated by the Holder
to receive Warrant Shares shall be deemed to have become holder of record of
such Warrant Shares as of the Date of Exercise of this Warrant. The Company
shall, upon request of the Holder, if available, use its best efforts to deliver
Warrant Shares hereunder electronically through the Depository Trust Corporation
or another established clearing corporation

                                     D-1-2
<PAGE>   66

performing similar functions. To effect an exercise hereunder, the Holder shall
not be required to physically surrender this Warrant to the Company unless all
the Warrant Shares have been exercised. Exercises hereunder shall have the
effect of lowering the number of Warrant Shares in an amount equal to the
applicable exercise, which shall be evidenced by entries set forth in the
Exercise Schedule. The Holder and the Company shall maintain records showing the
number of Warrant Shares exercised and the date of such exercises . In the event
of any dispute or discrepancy, the records of the Holder shall be controlling
and determinative in the absence of manifest error. The Holder and any assignee,
by acceptance of this Warrant, acknowledge and agree that, by reason of the
provisions of this paragraph, following exercise of a portion of this Warrant,
the number of shares issuable upon exercise of this Warrant may be less than the
amount stated on the face hereof.

                  A "Date of Exercise" means the date on which the Company shall
have received (i) the Form of Election to Purchase completed and duly signed,
and (ii) payment of the Exercise Price for the number of Warrant Shares so
indicated by the Holder to be purchased.

                  (c) The "Exercise Price" for the Warrant Shares equals the
lesser of $7.00 (subject to equitable adjustment for stock splits, reverse stock
splits, and similar events) and the average of the Per Share Market Values for
the five Trading Days immediately preceding the date of the exercise, provided,
that, for the first 90 days following the Closing Date (as defined in the
Purchase Agreement), the Exercise Price may not be less than $7.00 (subject to
equitable adjustment for stock splits, reverse stock splits, and similar
events). The Exercise Price shall be subject to adjustment in accordance with
Section 8.

         4.       Piggyback Registration Rights. This Warrant is subject to
the piggyback registration rights granted under the Registration Rights
Agreement and such piggyback registration rights shall continue until all of the
Holder's Warrant Shares have been sold in accordance with an effective
registration statement or upon the Expiration Date. The Company will pay all
registration expenses in connection therewith.

         5.       Payment of Taxes. The Company will pay all documentary stamp
taxes attributable to the issuance of Warrant Shares upon the exercise of this
Warrant; provided, however, that the Company shall not be required to pay any
tax which may be payable in respect of any transfer involved in the registration
of any certificates for Warrant Shares or Warrants in a name other than that of
the Holder. The Holder shall be responsible for all other tax liability that may
arise as a result of holding or transferring this Warrant or receiving Warrant
Shares upon exercise hereof.

         6.       Replacement of Warrant. If this Warrant is mutilated, lost,
stolen or destroyed, the Company shall issue or cause to be issued in exchange
and substitution for and upon cancellation hereof, or in lieu of and
substitution for this Warrant, a New Warrant, but only upon receipt of evidence
reasonably satisfactory to the Company of such loss, theft or destruction and
indemnity, if requested, satisfactory to it. Applicants for a New Warrant under
such circumstances shall also comply with such other reasonable regulations and
procedures and pay such other reasonable charges as the Company may prescribe.

                                     D-1-3
<PAGE>   67

         7.       Reservation of Warrant Shares. The Company covenants that
it will at all times reserve and keep available out of the aggregate of its
authorized but unissued Common Stock, solely for the purpose of enabling it to
issue Warrant Shares upon exercise of this Warrant as herein provided, the
number of Warrant Shares which are then issuable and deliverable upon the
exercise of this entire Warrant, free from preemptive rights or any other actual
contingent purchase rights of persons other than the Holder (taking into account
the adjustments and restrictions of Section 8). The Company covenants that all
Warrant Shares that shall be so issuable and deliverable shall, upon issuance
and the payment of the applicable Exercise Price in accordance with the terms
hereof, be duly and validly authorized, issued and fully paid and nonassessable.

         8.       Certain Adjustments.  The Exercise Price and number of Warrant
Shares issuable upon exercise of this Warrant are subject to adjustment from
time to time as set forth in this Section 8.

                  (a) If the Company, at any time while this Warrant is
outstanding, (i) shall pay a stock dividend (except scheduled dividends paid on
outstanding preferred stock as of the date hereof which contain a stated
dividend rate) or otherwise make a distribution or distributions on shares of
its Common Stock or on any other class of capital stock payable in shares of
Common Stock, (ii) subdivide outstanding shares of Common Stock into a larger
number of shares, or (iii) combine outstanding shares of Common Stock into a
smaller number of shares, the Exercise Price shall be multiplied by a fraction
of which the numerator shall be the number of shares of Common Stock (excluding
treasury shares, if any) outstanding before such event and of which the
denominator shall be the number of shares of Common Stock (excluding treasury
shares, if any) outstanding after such event. Any adjustment made pursuant to
this Section shall become effective immediately after the record date for the
determination of stockholders entitled to receive such dividend or distribution
and shall become effective immediately after the effective date in the case of a
subdivision or combination, and shall apply to successive subdivisions and
combinations.

                  (b) In case of any reclassification of the Common Stock or any
compulsory share exchange pursuant to which the Common Stock is converted into
other securities, cash or property, then the Holder shall have the right
thereafter to exercise this Warrant only into the shares of stock and other
securities and property receivable upon or deemed to be held by holders of
Common Stock following such reclassification or share exchange, and the Holder
shall be entitled upon such event to receive such amount of securities or
property equal to the amount of Warrant Shares such Holder would have been
entitled to had such Holder exercised this Warrant immediately prior to such
reclassification or share exchange. The terms of any such reclassification or
share exchange shall include such terms so as to continue to give to the Holder
the right to receive the securities or property set forth in this Section 8(b)
upon any exercise following any such reclassification or share exchange.

                  (c) If the Company, at any time while this Warrant is
outstanding, shall distribute to all holders of Common Stock (and not to holders
of this Warrant) evidences of its indebtedness or assets or rights or warrants
to subscribe for or purchase any security (excluding those referred to in
Sections 8(a), (b) and (d)), then in each such case the Exercise Price shall be
determined by multiplying the Exercise Price in effect immediately prior to the
record date fixed for

                                     D-1-4
<PAGE>   68

determination of stockholders entitled to receive such distribution by a
fraction of which the denominator shall be the Exercise Price determined as of
the record date mentioned above, and of which the numerator shall be such
Exercise Price on such record date less the then fair market value at such
record date of the portion of such assets or evidence of indebtedness so
distributed applicable to one outstanding share of Common Stock as determined by
the Company's independent certified public accountants that regularly examines
the financial statements of the Company (an "Appraiser").

                  (d) If the Company or any subsidiary thereof, as applicable
with respect to Common Stock Equivalents (as defined below), at any time while
this Warrant is outstanding, shall issue shares of Common Stock or rights,
warrants, options or other securities, including securities issued to the Holder
as of the date hereof, or debt that are convertible into or exchangeable for
shares of Common Stock ("Common Stock Equivalents"), entitling any Person to
acquire shares of Common Stock at a price per share less than the greater of the
Closing Price on such date of issuance and the Exercise Price (if the holder of
the Common Stock or Common Stock Equivalent so issued shall at any time, whether
by operation of purchase price adjustments, reset provisions, floating
conversion, exercise or exchange prices or otherwise, or due to warrants,
options or rights issued in connection with such issuance, be entitled to
receive shares of Common Stock at a price less than the Exercise Price, such
issuance shall be deemed to have occurred for less than the Exercise Price),
then, at the sole option of the Holder, the Exercise Price shall be adjusted to
mirror the conversion, exchange or purchase price for such Common Stock
Equivalents (including any reset provisions thereof), provided, that for
purposes hereof, all shares of Common Stock that are issuable upon conversion,
exercise or exchange of Common Stock Equivalents shall be deemed outstanding
immediately after the issuance of such Common Stock Equivalents. Such adjustment
shall be made whenever such shares of Common Stock or Common Stock Equivalents
are issued. Notwithstanding to the contrary anything herein, this Section shall
not apply to: (i) issuance of options and warrants to employees, officers and
directors of the Company, and the issuance of Common Stock upon exercise of such
options and warrants granted under any stock option plan hereinafter duly
adopted by the Company, (ii) issuance of Common Stock or Common Stock
Equivalents as part payment of the purchase price in (A) the acquisition of
assets or a business by the Company or (B) in connection with the acquisition of
goods or a license by the Company and (iii) as royalty payments in connection
with or under a firm underwritten primary offering of the Company's stock in
which the full purchase price is paid upon the first closing thereof (which
shall not include equity lines of credit or any similar financing structure).

                  (e) In case of any (1) merger or consolidation of the Company
with or into another Person, or (2) sale by the Company of more than one-half of
the assets of the Company (on a book value basis) in one or a series of related
transactions, the Holder shall have the right thereafter to (A) exercise this
Warrant for the shares of stock and other securities, cash and property
receivable upon or deemed to be held by holders of Common Stock following such
merger, consolidation or sale, and the Holder shall be entitled upon such event
or series of related events to receive such amount of securities, cash and
property as the Common Stock for which this Warrant could have been exercised
immediately prior to such merger, consolidation or sales would have been
entitled or (B) in the case of a merger or consolidation, require the Company to
pay to the Holder, in cash, 120% of the Black Scholes value of this Warrant. The
terms of any such merger, sale or

                                     D-1-5
<PAGE>   69

consolidation shall include such terms so as continue to give the Holder the
right to receive the securities, cash and property set forth in this Section
upon any conversion or redemption following such event. This provision shall
similarly apply to successive such events.

                  (f) For the purposes of this Section 8, the following clauses
shall also be applicable:

                      (i)  Record Date.  In case the Company shall take a record
of the holders of its Common Stock for the purpose of entitling them (A) to
receive a dividend or other distribution payable in Common Stock or in
securities convertible or exchangeable into shares of Common Stock, or (B) to
subscribe for or purchase Common Stock or securities convertible or exchangeable
into shares of Common Stock, then such record date shall be deemed to be the
date of the issue or sale of the shares of Common Stock deemed to have been
issued or sold upon the declaration of such dividend or the making of such other
distribution or the date of the granting of such right of subscription or
purchase, as the case may be.

                      (ii)  Treasury Shares.  The number of shares of Common
Stock outstanding at any given time shall not include shares owned or held by or
for the account of the Company, and the disposition of any such shares shall be
considered an issue or sale of Common Stock.

                  (g) All calculations under this Section 8 shall be made to the
nearest cent or the nearest 1/100th of a share, as the case may be.

                  (h) Whenever the Exercise Price is adjusted pursuant to
Section 8(c) above, the Holder, after receipt of the determination by the
Appraiser, shall have the right to select an additional appraiser (which shall
be a nationally recognized accounting firm), in which case the adjustment shall
be equal to the average of the adjustments recommended by each of the Appraiser
and such appraiser. The Holder shall promptly mail or cause to be mailed to the
Company, a notice setting forth the Exercise Price after such adjustment and
setting forth a brief statement of the facts requiring such adjustment. Such
adjustment shall become effective immediately after the record date mentioned
above.

                  (i) If:

                        (i)         the Company shall declare a dividend (or any
                                    other distribution) on its Common Stock; or

                       (ii)         the Company shall declare a special
                                    nonrecurring cash dividend on or a
                                    redemption of its Common Stock; or

                      (iii)         the Company shall authorize the granting to
                                    all holders of the Common Stock rights or
                                    warrants to subscribe for or purchase any
                                    shares of capital stock of any class or of
                                    any rights; or

                                     D-1-6

<PAGE>   70

                       (iv)         the approval of any stockholders of the
                                    Company shall be required in connection with
                                    any reclassification of the Common Stock,
                                    any consolidation or merger to which the
                                    Company is a party, any sale or transfer
                                    of all or substantially all of the assets of
                                    the Company, or any compulsory share
                                    exchange whereby the Common Stock is
                                    converted into other securities, cash or
                                    property; or

                        (v)         the Company shall authorize the voluntary
                                    dissolution, liquidation or winding up of
                                    the affairs of the Company,

then the Company shall cause to be mailed to each Holder at their last addresses
as they shall appear upon the Warrant Register, at least 20 calendar days prior
to the applicable record or effective date hereinafter specified, a notice
stating (x) the date on which a record is to be taken for the purpose of such
dividend, distribution, redemption, rights or warrants, or if a record is not to
be taken, the date as of which the holders of Common Stock of record to be
entitled to such dividend, distributions, redemption, rights or warrants are to
be determined or (y) the date on which such reclassification, consolidation,
merger, sale, transfer or share exchange is expected to become effective or
close, and the date as of which it is expected that holders of Common Stock of
record shall be entitled to exchange their shares of Common Stock for
securities, cash or other property deliverable upon such reclassification,
consolidation, merger, sale, transfer, share exchange, dissolution, liquidation
or winding up; provided, however, that the failure to mail such notice or any
defect therein or in the mailing thereof shall not affect the validity of the
corporate action required to be specified in such notice.

         9.       Payment of Exercise Price.  The Holder shall pay the Exercise
Price in one of the following manners:

                  (a) Cash Exercise.  The Holder may deliver immediately
available funds; or

                  (b) Cashless Exercise. The Holder may surrender this Warrant
to the Company together with a notice of cashless exercise, in which event the
Company shall issue to the Holder the number of Warrant Shares determined as
follows:

                                    X = Y [(A-B)/A]
         where:
                                    X = the number of Warrant Shares to be
         issued to the Holder.

                                    Y = the number of Warrant Shares with
                                    respect to which this Warrant is being
                                    exercised.

                                     D-1-7
<PAGE>   71

                                    A = the average of the closing sale prices
                                    of the Common Stock for the five (5) trading
                                    days immediately prior to (but not
                                    including) the Date of Exercise.

                                    B = the Exercise Price.

For purposes of Rule 144 promulgated under the Securities Act, it is intended,
understood and acknowledged that the Warrant Shares issued in a cashless
exercise transaction shall be deemed to have been acquired by the Holder, and
the holding period for the Warrant Shares shall be deemed to have been
commenced, on the issue date.

         10.      Certain Exercise Restrictions.

                  (a) A Holder may not exercise this Warrant to the extent such
exercise would result in the Holder, together with any affiliate thereof,
beneficially owning (as determined in accordance with Section 13(d) of the
Securities Exchange Act of 1934, as amended (the "Exchange Act") and the rules
promulgated thereunder) in excess of 4.999% of the then issued and outstanding
shares of Common Stock, including shares issuable upon such exercise and held by
such Holder after application of this Section. Since the Holder will not be
obligated to report to the Company the number of shares of Common Stock it may
hold at the time of an exercise hereunder, unless the exercise at issue would
result in the issuance of shares of Common Stock in excess of 4.999% of the then
outstanding shares of Common Stock without regard to any other shares which may
be beneficially owned by the Holder or an affiliate thereof, the Holder shall
have the authority and obligation to determine whether the restriction contained
in this Section will limit any particular exercise hereunder and to the extent
that the Holder determines that the limitation contained in this Section
applies, the determination of which portion of this Warrant is exercisable shall
be the responsibility and obligation of the Holder. If the Holder has delivered
a Form of Election to Purchase for a number of Warrant Shares that, without
regard to any other shares that the Holder or its affiliates may beneficially
own, would result in the issuance in excess of the permitted amount hereunder,
the Company shall notify the Holder of this fact and shall honor the exercise
for the maximum portion of this Warrant permitted to be exercised on such Date
of Exercise in accordance with the periods described herein and, at the option
of the Holder, either keep the portion of the Warrant tendered for exercise in
excess of the permitted amount hereunder for future exercises or return such
excess portion of the Warrant to the Holder. The provisions of this Section may
be waived by a Holder (but only as to itself and not to any other Holder) upon
not less than 61 days prior notice to the Company. Other Holders shall be
unaffected by any such waiver.

                  (b) A Holder may not exercise this Warrant to the extent such
exercise would result in the Holder, together with any affiliate thereof,
beneficially owning (as determined in accordance with Section 13(d) of the
Exchange Act and the rules promulgated thereunder) in excess of 9.999% of the
then issued and outstanding shares of Common Stock, including shares issuable
upon such exercise and held by such Holder after application of this Section.
Since the Holder will not be obligated to report to the Company the number of
shares of Common Stock it may hold at the time of an exercise hereunder, unless
the exercise at issue would result in the issuance of shares of Common  Stock
in excess of 9.999% of the then outstanding shares of Common

                                     D-1-8
<PAGE>   72

Stock without regard to any other shares which may be beneficially owned by the
Holder or an affiliate thereof, the Holder shall have the authority and
obligation to determine whether the restriction contained in this Section will
limit any particular exercise hereunder and to the extent that the Holder
determines that the limitation contained in this Section applies, the
determination of which portion of this Warrant is exercisable shall be the
responsibility and obligation of the Holder. If the Holder has delivered a Form
of Election to Purchase for a number of Warrant Shares that, without regard to
any other shares that the Holder or its affiliates may beneficially own, would
result in the issuance in excess of the permitted amount hereunder, the Company
shall notify the Holder of this fact and shall honor the exercise for the
maximum portion of this Warrant permitted to be exercised on such Date of
Exercise in accordance with the periods described herein and, at the option of
the Holder, either keep the portion of the Warrant tendered for exercise in
excess of the permitted amount hereunder for future exercises or return such
excess portion of the Warrant to the Holder. The provisions of this Section may
be waived by a Holder (but only as to itself and not to any other Holder) upon
not less than 61 days prior notice to the Company. Other Holders shall be
unaffected by any such waiver.

                  (c) If the Company Stock is then listed for trading on the
Nasdaq or the Nasdaq SmallCap Market and the Company has not obtained the
Shareholder Approval (as defined below), then the Company may not issue in
excess of 3,492,001.9 shares of Common Stock (which equals 19.999% of the number
of shares of Common Stock outstanding on the Trading Day immediately preceding
the date hereof) upon exercise of this Warrant, the Redeemable Warrants (as
defined in the purchase agreement dated the date hereof pursuant to which this
Warrant was issued) or conversion of the Preferred Stock (as defined in the
purchase agreement dated the date hereof pursuant to which this Warrant was
issued), in any case, at a price per share that is less than the Closing Price
on the Trading Day immediately preceding the date hereof (such number of shares,
the "Issuable Maximum"). Each Holder shall be entitled to a portion of the
Issuable Maximum equal to the quotient obtained by dividing (x) the number of
shares of Common Stock issued and sold to such Holder on the Date hereof by (y)
the number of shares of Common Stock issued and sold by the Company on the Date
hereof. If any Holder shall no longer hold Warrants then such Holder's remaining
portion of the Issuable Maximum shall be allocated pro-rata among the remaining
Holders. If on any Date of Exercise: (A) the Company Stock is listed for trading
on the Nasdaq or the Nasdaq SmallCap Market, (B) the Exercise Price then in
effect is such that the aggregate number of shares of Common Stock that would
then be issuable upon exercise in full of this Warrant, the Redemption Warrants
and conversion in full of the Preferred Stock, together with any shares of
Common Stock previously issued upon exercise of this Warrant, the Closing
Warrants and conversion of the Series A Stock, would equal or exceed the
Issuable Maximum, and (C) the Company shall not have previously obtained the
vote of shareholders, if any, as may be required by the applicable rules and
regulations of the Nasdaq Stock Market to approve the issuance of shares of
Common Stock in excess of the Issuable Maximum pursuant to the terms hereof (the
"Shareholder Approval"), then the Company shall issue to the Holder a number of
shares of Common Stock equal to the Issuable Maximum and, with respect to the
shares whose issuance would result in an issuance of shares of Common Stock in
excess of the Issuable Maximum, (the "Excess Warrant Shares"), the Holder shall
have the option to require the Company to either (1) use its best efforts to
obtain the Shareholder Approval applicable to such issuance as soon as possible,
but in any event no later than 60 days after such request (such 60th day, the
"Target Date") or (2) pay to the Holder, within one (1)

                                     D-1-9

<PAGE>   73

Trading Day from the request therefor, an amount in cash equal to the product of
(x) the Excess Warrant Shares multiplied by (y) the closing sales price of the
Common Stock on (a) the Target Date or (b) the Date of Exercise giving rise to
the obligation to seek Shareholder Approval, whichever is greater (the "Cash
Payment"). In the event the Holder has elected to require the Company to seek
the Shareholder Approval pursuant to clause (1) of the immediately preceding
sentence and the Company does not obtain the Shareholder Approval on or prior to
the Target Date, then, on the Target Date, the Company shall pay the Cash
Payment to the Holder. If the Company fails to pay the Cash Payment in full
pursuant to this Section within seven (7) days after the date payable, the
Company will pay interest on such amount at a rate of 18% per annum, or such
lesser maximum amount that is permitted to be paid by applicable law, to the
Holder, accruing daily from the date payable until such amount, plus all such
interest thereon, is paid in full. The Company and the Holder understand and
agree that shares of Common Stock issued upon exercise of this Warrant and then
held by the Holder or an affiliate thereof may not cast votes or be deemed
outstanding for purposes of any vote to obtain the Shareholder Approval.

                  11. Fractional Shares. The Company shall not be required to
issue or cause to be issued fractional Warrant Shares on the exercise of this
Warrant. The number of full Warrant Shares which shall be issuable upon the
exercise of this Warrant shall be computed on the basis of the aggregate number
of Warrant Shares purchasable on exercise of this Warrant so presented. If any
fraction of a Warrant Share would, except for the provisions of this Section, be
issuable on the exercise of this Warrant, the Company shall pay an amount in
cash equal to the Exercise Price multiplied by such fraction.

                  12. Notices. Any and all notices or other communications or
deliveries hereunder shall be in writing and shall be deemed given and effective
on the earliest of (i) the date of transmission, if such notice or communication
is delivered via facsimile at the facsimile telephone number specified in this
Section prior to 6:30 p.m. (New York City time) on a business day, (ii) the
business day after the date of transmission, if such notice or communication is
delivered via facsimile at the facsimile telephone number specified in this
Section later than 6:30 p.m. (New York City time) on any date and earlier than
11:59 p.m. (New York City time) on such date, (iii) the business day following
the date of mailing, if sent by nationally recognized overnight courier service,
or (iv) upon actual receipt by the party to whom such notice is required to be
given. The addresses for such communications shall be: (i) if to the Company, to
499 Thornall Street, Edison, New Jersey, 08837, facsimile: (732) 362-2123,
attention Chief Financial Officer, or (ii) if to the Holder, to the Holder at
the address or facsimile number appearing on the Warrant Register or such other
address or facsimile number as the Holder may provide to the Company in
accordance with this Section.

                  13. Warrant Agent. The Company shall serve as warrant agent
under this Warrant. Upon thirty days' notice to the Holder, the Company may
appoint a new warrant agent. Any corporation into which the Company or any new
warrant agent may be merged or any corporation resulting from any consolidation
to which the Company or any new warrant agent shall be a party or any
corporation to which the Company or any new warrant agent transfers
substantially all of its corporate trust or shareholders services business shall
be a successor warrant agent under this Warrant without any further act. Any
such successor warrant agent shall promptly cause notice

                                     D-1-10
<PAGE>   74

of its succession as warrant agent to be mailed (by first class mail, postage
prepaid) to the Holder at the Holder's last address as shown on the Warrant
Register.

         14.      Miscellaneous.

                  (a) This Warrant shall be binding on and inure to the benefit
of the parties hereto and their respective successors and assigns. This Warrant
may be amended only in writing signed by the Company and the Holder and their
successors and assigns.

                  (b) Subject to Section 14(a), above, nothing in this Warrant
shall be construed to give to any person or corporation other than the Company
and the Holder any legal or equitable right, remedy or cause under this Warrant.
This Warrant shall inure to the sole and exclusive benefit of the Company and
the Holder.

                  (c) The corporate laws of the State of New Jersey shall govern
all issues concerning the relative rights of the Company and its stockholders.
All other questions concerning the construction, validity, enforcement and
interpretation of this Warrant shall be governed by and construed and enforced
in accordance with the internal laws of the State of New York, without regard to
the principles of conflicts of law thereof. The Company and the Holder hereby
irrevocably submit to the exclusive jurisdiction of the state and federal courts
sitting in the City of New York, borough of Manhattan, for the adjudication of
any dispute hereunder or in connection herewith or with any transaction
contemplated hereby or discussed herein, and hereby irrevocably waives, and
agrees not to assert in any suit, action or proceeding, any claim that it is not
personally subject to the jurisdiction of any such court, or that such suit,
action or proceeding is improper. Each of the Company and the Holder hereby
irrevocably waives personal service of process and consents to process being
served in any such suit, action or proceeding by receiving a copy thereof sent
to the Company at the address in effect for notices to it under this instrument
and agrees that such service shall constitute good and sufficient service of
process and notice thereof. Nothing contained herein shall be deemed to limit in
any way any right to serve process in any manner permitted by law.

                  (d) The headings herein are for convenience only, do not
constitute a part of this Warrant and shall not be deemed to limit or affect any
of the provisions hereof.

                  (e) In case any one or more of the provisions of this Warrant
shall be invalid or unenforceable in any respect, the validity and
enforceability of the remaining terms and provisions of this Warrant shall not
in any way be affected or impaired thereby and the parties will attempt in good
faith to agree upon a valid and enforceable provision which shall be a
commercially reasonable substitute therefor, and upon so agreeing, shall
incorporate such substitute provision in this Warrant.

THE SECURITIES COMMISSION OF ANY STATE IN RELIANCE UPON AN EXEMPTION FROM
REGISTRATION UNDER SECURITIES ACT OF 1933, AS AMENDED (THE "SECURITIES ACT"),

                                 SERANOVA, INC.

                               REDEMPTION WARRANT

Warrant No.[ ]                                         Dated: September __, 2000

         SeraNova, Inc., a New Jersey corporation (the "Company"), hereby
certifies that, for value received, [ ] or its registered assigns ("Holder"), is
entitled, subject to the terms set forth below, to purchase from the Company
[160,000] shares of common stock, $.01 par value per share (the "Common Stock"),
of the Company (each such share, a "Warrant Share" and all such shares, the
"Warrant Shares") at the Exercise Price set forth in Section 3, at any time and
from time to time from and after the date on which the Company delivers an
Optional Redemption Notice under the Certificate of Designation (as defined in
the Purchase Agreement) issued to the original Holder, in accordance with the
Certificate of Designation filed by the Company on the date hereof with respect
to the Company's 6% Series A Convertible Preferred Stock (the "Series A Stock")
issued to the original Holder, and through and including the fifth year
following the vesting of this Warrant anniversary of the date of the Company
delivers such Optional Redemption Notice (the "Expiration Date"), and subject to
the following terms and conditions:

                  1. Registration of Warrant. The Company shall register this
Warrant, upon records to be maintained by the Company for that purpose (the
"Warrant Register"), in the name of the record Holder hereof from time to time.
The Company may deem and treat the registered Holder of this Warrant as the
absolute owner hereof for the purpose of any exercise hereof or any distribution
to the Holder, and for all other purposes, and the Company shall not be affected
by notice to the contrary.

                                     D-2-1
<PAGE>   80

         2.       Registration of Transfers and Exchanges.

                  (a) The Company shall register the transfer of any portion of
this Warrant in the Warrant Register, upon surrender of this Warrant, with the
Form of Assignment attached hereto duly completed and signed, to the Transfer
Agent or to the Company at its address for notice set forth in Section 12. Upon
any such registration or transfer, a new warrant to purchase Common Stock, in
substantially the form of this Warrant (any such new warrant, a "New Warrant"),
evidencing the portion of this Warrant so transferred shall be issued to the
transferee and a New Warrant evidencing the remaining portion of this Warrant
not so transferred, if any, shall be issued to the transferring Holder. The
acceptance of the New Warrant by the transferee thereof shall be deemed the
acceptance of such transferee of all of the rights and obligations of a holder
of a Warrant.

                  (b) This Warrant is exchangeable, upon the surrender hereof by
the Holder to the office of the Company at its address for notice set forth in
Section 12 for one or more New Warrants, evidencing in the aggregate the right
to purchase the number of Warrant Shares which may then be purchased hereunder.
Any such New Warrant will be dated the date of such exchange.

         3.       Duration and Exercise of Warrants.

                  (a) This Warrant shall be exercisable by the registered Holder
on any business day before 6:30 P.M., New York City time, at any time and from
time to time on or after the date the Company delivers an Optional Redemption
Notice with respect to the A Series Stock issued to the original Holder under
and including the Expiration Date. At 6:30 P.M., New York City time on the
earlier to occur of (i) Expiration Date, or (ii) the date on which the Series A
Stock issued to the original Holder is converted to Common Stock or otherwise
redeemed or retired in any manner prior to delivery of an Optional Redemption
Notice, the portion of this Warrant not exercised prior thereto shall be and
become void and of no value. Prior to the Expiration Date, the Company may not
call or otherwise redeem this Warrant.

                  (b) Upon delivery of a duly completed and signed Form of
Election to Purchase attached hereto (and the grid attached hereto as Annex A)
duly completed and signed, to the Company at its address for notice set forth in
Section 12 and upon payment of the Exercise Price multiplied by the number of
Warrant Shares that the Holder intends to purchase hereunder, in the manner
provided hereunder, all as specified by the Holder in the Form of Election to
Purchase, the Company shall promptly (but in no event later than 3 business days
after the Date of Exercise (as defined herein)) issue or cause to be issued and
cause to be delivered to or upon the written order of the Holder and in such
name or names as the Holder may designate, a certificate for the Warrant Shares
issuable upon such exercise, free of restrictive legends except (i) either in
the event that a registration statement covering the resale of the Warrant
Shares and naming the Holder as a selling stockholder thereunder is not then
effective or the Warrant Shares are not freely transferable without volume
restrictions pursuant to Rule 144(k) promulgated under the Securities Act of
1933, as amended (the "Securities Act"), or (ii) if this Warrant shall have been
issued pursuant to a written agreement between the original Holder and the
Company, as required by such agreement. Any person so designated by the Holder
to receive Warrant Shares shall be deemed to have become

                                     D-2-2
<PAGE>   81

holder of record of such Warrant Shares as of the Date of Exercise of this
Warrant. The Company shall, upon request of the Holder, if available, use its
best efforts to deliver Warrant Shares hereunder electronically through the
Depository Trust Corporation or another established clearing corporation
performing similar functions. To effect an exercise hereunder, the Holder shall
not be required to physically surrender this Warrant to the Company unless all
the Warrant Shares have been exercised. Exercises hereunder shall have the
effect of lowering the number of Warrant Shares in an amount equal to the
applicable exercise, which shall be evidenced by entries set forth in the
Exercise Schedule. The Holder and the Company shall maintain records showing the
number of Warrant Shares exercised and the date of such exercises . In the event
of any dispute or discrepancy, the records of the Holder shall be controlling
and determinative in the absence of manifest error. The Holder and any assignee,
by acceptance of this Warrant, acknowledge and agree that, by reason of the
provisions of this paragraph, following exercise of a portion of this Warrant,
the number of shares issuable upon exercise of this Warrant may be less than the
amount stated on the face hereof.

                  A "Date of Exercise" means the date on which the Company shall
have received (i) the Form of Election to Purchase completed and duly signed,
and (ii) payment of the Exercise Price for the number of Warrant Shares so
indicated by the Holder to be purchased.

                  (c) The "Exercise Price" for the Warrant Shares equals the
lesser of $7.00 (subject to equitable adjustment for stock splits, reverse stock
splits, and similar events) and the Closing Price on the Trading Day immediately
preceding the date of the exercise, provided, that, for the first 90 days
following the Closing Date (as defined in the Purchase Agreement), the Exercise
Price may not be less than $7.00 (subject to equitable adjustment for stock
splits, reverse stock splits, and similar events). The Exercise Price shall be
subject to adjustment in accordance with Section 8.

                  4. Piggyback Registration Rights. This Warrant is subject to
the piggyback registration rights granted under the Registration Rights
Agreement and such piggyback registration rights shall continue until all of the
Holder's Warrant Shares have been sold in accordance with an effective
registration statement or upon the Expiration Date. The Company will pay all
registration expenses in connection therewith.

                  5. Payment of Taxes. The Company will pay all documentary
stamp taxes attributable to the issuance of Warrant Shares upon the exercise of
this Warrant; provided, however, that the Company shall not be required to pay
any tax which may be payable in respect of any transfer involved in the
registration of any certificates for Warrant Shares or Warrants in a name other
than that of the Holder. The Holder shall be responsible for all other tax
liability that may arise as a result of holding or transferring this Warrant or
receiving Warrant Shares upon exercise hereof.

                  6. Replacement of Warrant. If this Warrant is mutilated, lost,
stolen or destroyed, the Company shall issue or cause to be issued in exchange
and substitution for and upon cancellation hereof, or in lieu of and
substitution for this Warrant, a New Warrant, but only upon receipt of evidence
reasonably satisfactory to the Company of such loss, theft or destruction and
indemnity, if requested, satisfactory to it. Applicants for a New Warrant under
such circumstances shall also comply with such other reasonable regulations and
procedures and pay such other reasonable charges as the Company may prescribe.

                                     D-2-3
<PAGE>   82

         7.       Reservation of Warrant Shares. The Company covenants that
it will at all times reserve and keep available out of the aggregate of its
authorized but unissued Common Stock, solely for the purpose of enabling it to
issue Warrant Shares upon exercise of this Warrant as herein provided, the
number of Warrant Shares which are then issuable and deliverable upon the
exercise of this entire Warrant, free from preemptive rights or any other actual
contingent purchase rights of persons other than the Holder (taking into account
the adjustments and restrictions of Section 8). The Company covenants that all
Warrant Shares that shall be so issuable and deliverable shall, upon issuance
and the payment of the applicable Exercise Price in accordance with the terms
hereof, be duly and validly authorized, issued and fully paid and nonassessable.

         8.       Certain Adjustments.  The Exercise Price and number of Warrant
Shares issuable upon exercise of this Warrant are subject to adjustment from
time to time as set forth in this Section 8.

                  (a) In case of any reclassification of the Common Stock or any
compulsory share exchange pursuant to which the Common Stock is converted into
other securities, cash or property, then the Holder shall have the right
thereafter to exercise this Warrant only into the shares of stock and other
securities and property receivable upon or deemed to be held by holders of
Common Stock following such reclassification or share exchange, and the Holder
shall be entitled upon such event to receive such amount of securities or
property equal to the amount of Warrant Shares such Holder would have been
entitled to had such Holder exercised this Warrant immediately prior to such
reclassification or share exchange. The terms of any such reclassification or
share exchange shall include such terms so as to continue to give to the Holder
the right to receive the securities or property set forth in this Section 8(b)
upon any exercise following any such reclassification or share exchange.

                  (b) If the Company, at any time while this Warrant is
outstanding, shall distribute to all holders of Common Stock (and not to holders
of this Warrant) evidences of its indebtedness or assets or rights or warrants
to subscribe for or purchase any security (excluding those referred to in
Sections 8(a), (b) and (d)), then in each such case the Exercise Price shall be
determined by multiplying the Exercise Price in effect immediately prior to the
record date fixed for determination of stockholders entitled to receive such
distribution by a fraction of which the denominator shall be the Exercise Price
determined as of the record date mentioned above, and of which the numerator
shall be such Exercise Price on such record date less the then fair market value
at such record date of the portion of such assets or evidence of indebtedness so
distributed applicable to one outstanding share of Common Stock as determined by
the Company's independent certified public accountants that regularly examines
the financial statements of the Company (an "Appraiser").

                  (c) If the Company or any subsidiary thereof, as applicable
with respect to Common Stock Equivalents (as defined below), at any time while
this Warrant is outstanding, shall issue shares of Common Stock or rights,
warrants, options or other securities, including securities issued to the Holder
as of the date hereof, or debt that are convertible into or exchangeable for
shares of Common Stock ("Common Stock Equivalents"), entitling any Person to
acquire shares

                                     D-2-4
<PAGE>   83

of Common Stock at a price per share less than the greater of the Closing Price
on such date of issuance and the Exercise Price (if the holder of the Common
Stock or Common Stock Equivalent so issued shall at any time, whether by
operation of purchase price adjustments, reset provisions, floating conversion,
exercise or exchange prices or otherwise, or due to warrants, options or rights
issued in connection with such issuance, be entitled to receive shares of Common
Stock at a price less than the Exercise Price, such issuance shall be deemed to
have occurred for less than the Exercise Price), then, at the sole option of the
Holder, the Exercise Price shall be adjusted to mirror the conversion, exchange
or purchase price for such Common Stock Equivalents (including any reset
provisions thereof), provided, that for purposes hereof, all shares of Common
Stock that are issuable upon conversion, exercise or exchange of Common Stock
Equivalents shall be deemed outstanding immediately after the issuance of such
Common Stock Equivalents. Such adjustment shall be made whenever such shares of
Common Stock or Common Stock Equivalents are issued. Notwithstanding to the
contrary anything herein, this Section shall not apply to: (i) issuance of
options and warrants to employees, officers and directors of the Company, and
the issuance of Common Stock upon exercise of such options and warrants granted
under any stock option plan hereinafter duly adopted by the Company, (ii)
issuance of Common Stock or Common Stock Equivalents as part payment of the
purchase price in (A) the acquisition of assets or a business by the Company or
(B) in connection with the acquisition of goods or a license by the Company and
(iii) as royalty payments in connection with or under a firm underwritten
primary offering of the Company's stock in which the full purchase price is paid
upon the first closing thereof (which shall not include equity lines of credit
or any similar financing structure).

                  (d) In case of any (1) merger or consolidation of the Company
with or into another Person, or (2) sale by the Company of more than one-half of
the assets of the Company (on a book value basis) in one or a series of related
transactions, the Holder shall have the right thereafter to (A) exercise this
Warrant for the shares of stock and other securities, cash and property
receivable upon or deemed to be held by holders of Common Stock following such
merger, consolidation or sale, and the Holder shall be entitled upon such event
or series of related events to receive such amount of securities, cash and
property as the Common Stock for which this Warrant could have been exercised
immediately prior to such merger, consolidation or sales would have been
entitled or (B) in the case of a merger or consolidation, require the Company to
pay to the Holder, in cash, 120% of the Black Scholes value of this Warrant. The
terms of any such merger, sale or consolidation shall include such terms so as
continue to give the Holder the right to receive the securities, cash and
property set forth in this Section upon any conversion or redemption following
such event. This provision shall similarly apply to successive such events.

         For the purposes of this Warrant, "Closing Price" shall mean on any
particular date (a) the closing sale price per share of Common Stock on such
date on the Nasdaq or on such Subsequent Market on which the shares of Common
Stock are then listed or quoted, or if there is no such price on such date, then
the closing sale price on the Nasdaq or on such Subsequent Market on the date
nearest preceding such date, or (b) if the shares of Common Stock are not then
listed or quoted on the Nasdaq or a Subsequent Market, the closing sale price
for a share of Common Stock in the over-the-counter market, as reported by the
National Quotation Bureau Incorporated or similar organization or agency
succeeding to its functions of reporting prices) at the close of business on
such date, or (c) if the shares of Common Stock are not then reported by the
National Quotation

                                     D-2-5
<PAGE>   84

Bureau Incorporated (or similar organization or agency succeeding to its
functions of reporting prices), then the average of the "Pink Sheet" quotes for
the relevant conversion period, as determined in good faith by the Holder, or
(d) if the Common Stock are not then publicly traded the fair market value of a
share of Common Stock as determined by an Appraiser selected in good faith by
the Holders of a majority of the Warrants.

                  (e) For the purposes of this Section 8, the following clauses
shall also be applicable:

                      (i)  Record Date.  In case the Company shall take a record
of the holders of its Common Stock for the purpose of entitling them (A) to
receive a dividend or other distribution payable in Common Stock or in
securities convertible or exchangeable into shares of Common Stock, or (B) to
subscribe for or purchase Common Stock or securities convertible or exchangeable
into shares of Common Stock, then such record date shall be deemed to be the
date of the issue or sale of the shares of Common Stock deemed to have been
issued or sold upon the declaration of such dividend or the making of such other
distribution or the date of the granting of such right of subscription or
purchase, as the case may be.

                     (ii)  Treasury Shares.  The number of shares of Common
Stock outstanding at any given time shall not include shares owned or held by or
for the account of the Company, and the disposition of any such shares shall be
considered an issue or sale of Common Stock.

                  (f) All calculations under this Section 8 shall be made to the
nearest cent or the nearest 1/100th of a share, as the case may be.

                  (g) Whenever the Exercise Price is adjusted pursuant to
Section 8(c) above, the Holder, after receipt of the determination by the
Appraiser, shall have the right to select an additional appraiser (which shall
be a nationally recognized accounting firm), in which case the adjustment shall
be equal to the average of the adjustments recommended by each of the Appraiser
and such appraiser. The Holder shall promptly mail or cause to be mailed to the
Company, a notice setting forth the Exercise Price after such adjustment and
setting forth a brief statement of the facts requiring such adjustment. Such
adjustment shall become effective immediately after the record date mentioned
above.

                  (h) If:

                        (i)         the Company shall declare a dividend (or
                                    any other distribution) on its Common Stock;
                                    or

                       (ii)         the Company shall declare a special
                                    nonrecurring cash dividend on or a
                                    redemption of its Common Stock; or

                      (iii)         the Company shall authorize the granting to
                                    all holders of the Common Stock rights or
                                    warrants to subscribe

                                     D-2-6

<PAGE>   85

                                    for or purchase any  shares of capital stock
                                    of any class or of  any rights; or

                       (iv)         the approval of any stockholders of the
                                    Company shall be required in connection with
                                    any reclassification of the Common Stock,
                                    any consolidation or merger to which the
                                    Company is a party, any sale or transfer of
                                    all or substantially all of the assets of
                                    the Company, or any compulsory share
                                    exchange whereby the Common Stock is
                                    converted  into other securities, cash or
                                    property; or

                        (v)         the Company shall authorize the voluntary
                                    dissolution, liquidation or winding up of
                                    the affairs of the Company,

then the Company shall cause to be mailed to each Holder at their last addresses
as they shall appear upon the Warrant Register, at least 20 calendar days prior
to the applicable record or effective date hereinafter specified, a notice
stating (x) the date on which a record is to be taken for the purpose of such
dividend, distribution, redemption, rights or warrants, or if a record is not to
be taken, the date as of which the holders of Common Stock of record to be
entitled to such dividend, distributions, redemption, rights or warrants are to
be determined or (y) the date on which such reclassification, consolidation,
merger, sale, transfer or share exchange is expected to become effective or
close, and the date as of which it is expected that holders of Common Stock of
record shall be entitled to exchange their shares of Common Stock for
securities, cash or other property deliverable upon such reclassification,
consolidation, merger, sale, transfer, share exchange, dissolution, liquidation
or winding up; provided, however, that the failure to mail such notice or any
defect therein or in the mailing thereof shall not affect the validity of the
corporate action required to be specified in such notice.

         9.       Payment of Exercise Price.  The Holder shall pay the Exercise
Price in one of the following manners:

                  (a) Cash Exercise.  The Holder may deliver immediately
available funds; or

                  (b) Cashless Exercise. The Holder may surrender this Warrant
to the Company together with a notice of cashless exercise, in which event the
Company shall issue to the Holder the number of Warrant Shares determined as
follows:

                                    X = Y [(A-B)/A]
         where:
                                    X = the number of Warrant Shares to be
         issued to the Holder.

                                     D-2-7
<PAGE>   86

                                    Y = the number of Warrant Shares with
                                    respect to which this Warrant is being
                                    exercised.

                                    A = the average of the closing sale prices
                                    of the Common Stock for the five (5) trading
                                    days immediately prior to (but not
                                    including) the Date of Exercise.

                                    B = the Exercise Price.

For purposes of Rule 144 promulgated under the Securities Act, it is intended,
understood and acknowledged that the Warrant Shares issued in a cashless
exercise transaction shall be deemed to have been acquired by the Holder, and
the holding period for the Warrant Shares shall be deemed to have been
commenced, on the issue date.

         10.      Certain Exercise Restrictions.

                  (a) A Holder may not exercise this Warrant to the extent such
exercise would result in the Holder, together with any affiliate thereof,
beneficially owning (as determined in accordance with Section 13(d) of the
Securities Exchange Act of 1934, as amended (the "Exchange Act") and the rules
promulgated thereunder) in excess of 4.999% of the then issued and outstanding
shares of Common Stock, including shares issuable upon such exercise and held by
such Holder after application of this Section. Since the Holder will not be
obligated to report to the Company the number of shares of Common Stock it may
hold at the time of an exercise hereunder, unless the exercise at issue would
result in the issuance of shares of Common Stock in excess of 4.999% of the then
outstanding shares of Common Stock without regard to any other shares which may
be beneficially owned by the Holder or an affiliate thereof, the Holder shall
have the authority and obligation to determine whether the restriction contained
in this Section will limit any particular exercise hereunder and to the extent
that the Holder determines that the limitation contained in this Section
applies, the determination of which portion of this Warrant is exercisable shall
be the responsibility and obligation of the Holder. If the Holder has delivered
a Form of Election to Purchase for a number of Warrant Shares that, without
regard to any other shares that the Holder or its affiliates may beneficially
own, would result in the issuance in excess of the permitted amount hereunder,
the Company shall notify the Holder of this fact and shall honor the exercise
for the maximum portion of this Warrant permitted to be exercised on such Date
of Exercise in accordance with the periods described herein and, at the option
of the Holder, either keep the portion of the Warrant tendered for exercise in
excess of the permitted amount hereunder for future exercises or return such
excess portion of the Warrant to the Holder. The provisions of this Section may
be waived by a Holder (but only as to itself and not to any other Holder) upon
not less than 61 days prior notice to the Company. Other Holders shall be
unaffected by any such waiver.

                  (b) A Holder may not exercise this Warrant to the extent such
exercise would result in the Holder, together with any affiliate thereof,
beneficially owning (as determined in accordance with Section 13(d) of the
Exchange Act and the rules promulgated thereunder) in excess of 9.999% of the
then issued and outstanding shares of Common Stock, including shares issuable
upon such exercise and held by such Holder after application of this Section.
Since the

                                     D-2-8
<PAGE>   87

Holder will not be obligated to report to the Company the number of shares of
Common Stock it may hold at the time of an exercise hereunder, unless the
exercise at issue would result in the issuance of shares of Common Stock in
excess of 9.999% of the then outstanding shares of Common Stock without regard
to any other shares which may be beneficially owned by the Holder or an
affiliate thereof, the Holder shall have the authority and obligation to
determine whether the restriction contained in this Section will limit any
particular exercise hereunder and to the extent that the Holder determines that
the limitation contained in this Section applies, the determination of which
portion of this Warrant is exercisable shall be the responsibility and
obligation of the Holder. If the Holder has delivered a Form of Election to
Purchase for a number of Warrant Shares that, without regard to any other shares
that the Holder or its affiliates may beneficially own, would result in the
issuance in excess of the permitted amount hereunder, the Company shall notify
the Holder of this fact and shall honor the exercise for the maximum portion of
this Warrant permitted to be exercised on such Date of Exercise in accordance
with the periods described herein and, at the option of the Holder, either keep
the portion of the Warrant tendered for exercise in excess of the permitted
amount hereunder for future exercises or return such excess portion of the
Warrant to the Holder. The provisions of this Section may be waived by a Holder
(but only as to itself and not to any other Holder) upon not less than 61 days
prior notice to the Company. Other Holders shall be unaffected by any such
waiver.

                  (c) If the Company Stock is then listed for trading on the
Nasdaq or the Nasdaq SmallCap Market and the Company has not obtained the
Shareholder Approval (as defined below), then the Company may not issue in
excess of 3,492,001.9 shares of Common Stock (which equals 19.999% of the number
of shares of Common Stock outstanding on the Trading Day immediately preceding
the date hereof) upon exercise of this Warrant, the Closing Warrants (as defined
in the Purchase Agreement or conversion of the Series A Stock, in any case, at a
price per share that is less than the Closing Price on the Trading Day
immediately preceding the date hereof (such number of shares, the "Issuable
Maximum"). Each Holder shall be entitled to a portion of the Issuable Maximum
equal to the quotient obtained by dividing (x) the number of shares of Common
Stock issued and sold to such Holder on the Date hereof by (y) the number of
shares of Common Stock issued and sold by the Company on the Date hereof. If any
Holder shall no longer hold Warrants then such Holder's remaining portion of the
Issuable Maximum shall be allocated pro-rata among the remaining Holders. If on
any Date of Exercise: (A) the Company Stock is listed for trading on the Nasdaq
or the Nasdaq SmallCap Market, (B) the Exercise Price then in effect is such
that the aggregate number of shares of Common Stock that would then be issuable
upon exercise in full of this Warrant, the Closing Warrants and conversion in
full of the Series A Stock, together with any shares of Common Stock previously
issued upon exercise of this Warrant, the Closing Warrants and conversion of the
Series A Stock, would equal or exceed the Issuable Maximum, and (C) the Company
shall not have previously obtained the vote of shareholders, if any, as may be
required by the applicable rules and regulations of the Nasdaq Stock Market to
approve the issuance of shares of Common Stock in excess of the Issuable Maximum
pursuant to the terms hereof (the "Shareholder Approval"), then the Company
shall issue to the Holder a number of shares of Common Stock equal to the
Issuable Maximum and, with respect to the shares whose issuance would result in
an issuance of shares of Common Stock in excess of the Issuable Maximum, (the
"Excess Warrant Shares"), the Holder shall have the option to require the
Company to either (1) use its best efforts to obtain the Shareholder Approval
applicable to such issuance as soon as possible, but in any event no later than

                                     D-2-9
<PAGE>   88

60 days after such request (such 60th day, the "Target Date") or (2) pay to the
Holder, within one (1) Trading Day from the request therefor, an amount in cash
equal to the product of (x) the Excess Warrant Shares multiplied by (y) the
closing sales price of the Common Stock on (a) the Target Date or (b) the Date
of Exercise giving rise to the obligation to seek Shareholder Approval,
whichever is greater (the "Cash Payment"). In the event the Holder has elected
to require the Company to seek the Shareholder Approval pursuant to clause (1)
of the immediately preceding sentence and the Company does not obtain the
Shareholder Approval on or prior to the Target Date, then, on the Target Date,
the Company shall pay the Cash Payment to the Holder. If the Company fails to
pay the Cash Payment in full pursuant to this Section within seven (7) days
after the date payable, the Company will pay interest on such amount at a rate
of 18% per annum, or such lesser maximum amount that is permitted to be paid by
applicable law, to the Holder, accruing daily from the date payable until such
amount, plus all such interest thereon, is paid in full. The Company and the
Holder understand and agree that shares of Common Stock issued upon exercise of
this Warrant and then held by the Holder or an affiliate thereof may not cast
votes or be deemed outstanding for purposes of any vote to obtain the
Shareholder Approval.

         11.      Fractional Shares. The Company shall not be required to
issue or cause to be issued fractional Warrant Shares on the exercise of this
Warrant. The number of full Warrant Shares which shall be issuable upon the
exercise of this Warrant shall be computed on the basis of the aggregate number
of Warrant Shares purchasable on exercise of this Warrant so presented. If any
fraction of a Warrant Share would, except for the provisions of this Section, be
issuable on the exercise of this Warrant, the Company shall pay an amount in
cash equal to the Exercise Price multiplied by such fraction.

         12.      Notices. Any and all notices or other communications or
deliveries hereunder shall be in writing and shall be deemed given and effective
on the earliest of (i) the date of transmission, if such notice or communication
is delivered via facsimile at the facsimile telephone number specified in this
Section prior to 6:30 p.m. (New York City time) on a business day, (ii) the
business day after the date of transmission, if such notice or communication is
delivered via facsimile at the facsimile telephone number specified in this
Section later than 6:30 p.m. (New York City time) on any date and earlier than
11:59 p.m. (New York City time) on such date, (iii) the business day following
the date of mailing, if sent by nationally recognized overnight courier service,
or (iv) upon actual receipt by the party to whom such notice is required to be
given. The addresses for such communications shall be: (i) if to the Company, to
499 Thornall Street, Edison, New Jersey, 08837, facsimile: (732) 362-2123,
attention Chief Financial Officer, or (ii) if to the Holder, to the Holder at
the address or facsimile number appearing on the Warrant Register or such other
address or facsimile number as the Holder may provide to the Company in
accordance with this Section.

         13.      Warrant Agent. The Company shall serve as warrant agent
under this Warrant. Upon thirty days' notice to the Holder, the Company may
appoint a new warrant agent. Any corporation into which the Company or any new
warrant agent may be merged or any corporation resulting from any consolidation
to which the Company or any new warrant agent shall be a party or any
corporation to which the Company or any new warrant agent transfers
substantially all of its corporate trust or shareholders services business shall
be a successor warrant agent under

                                     D-2-10

this Warrant without any further act. Any such successor warrant agent shall
promptly cause notice of its succession as warrant agent to be mailed (by first
class mail, postage prepaid) to the Holder at the Holder's last address as shown
on the Warrant Register.

         14.      Miscellaneous.

                  (a) This Warrant shall be binding on and inure to the benefit

to the Company at the address in effect for notices to it under this instrument
and agrees that such service shall constitute good and sufficient service of

any way any right to serve process in any manner permitted by law.

                  (d) The headings herein are for convenience only, do not
constitute a part of this Warrant and shall not be deemed to limit or affect any
of the provisions hereof.

                  (e) In case any one or more of the provisions of this Warrant
shall be invalid or unenforceable in any respect, the validity and
enforceability of the remaining terms and provisions of this Warrant shall not
in any way be affected or impaired thereby and the parties will attempt in good
faith to agree upon a valid and enforceable provision which shall be a
commercially reasonable substitute therefor, and upon so agreeing, shall
incorporate such substitute provision in this Warrant.
