          ------------------------------------------------------------------
The Company acknowledges and agrees that the Purchaser is acting independently
and is not acting as a financial advisor or fiduciary of the Company (or in any
similar capacity) with respect to this Agreement or the transactions
contemplated hereby, that this Agreement and the transactions contemplated
hereby, and the relationship between the Purchaser and the Company is "arms-
length", and that any statement made by the Purchaser, or any of its
representatives or agents, in connection with this Agreement or the transactions
contemplated hereby, other than the representations and warranties of the
Purchaser contained herein, is not advice or a recommendation, is merely
incidental to the Purchaser's acquisition of the Securities and has not been
relied upon in any way by the Company, its officers, directors or other
representatives.  The Company further represents to the Purchaser that the
Company's decision to enter into this Agreement and the transactions
contemplated hereby has been based solely on an independent evaluation by the
Company and its representatives.

Designation and the Warrants, respectively, is binding upon it and enforceable
regardless of the dilution that such issuance may have on the ownership
interests of other stockholders.

                  LEGEND REMOVAL, TRANSFER, AND CERTAIN SALES

     5.1. Removal of Legend. The Legend shall be removed and the Company shall
          -----------------
issue a certificate without any legend to the holder of any Security upon which
such Legend is stamped, and a certificate for a Security shall be originally
issued without the Legend if (a) the sale of such Security is registered under
the Securities Act, (b) such holder provides the Company with an opinion of
counsel, in form, substance and scope customary for opinions of counsel in
comparable transactions to the effect that a public sale or transfer of such
Security may be made without registration under the Securities Act or (c) such
Security can be sold pursuant to Rule 144. The Purchaser agrees to sell all
Securities, including those represented by a certificate(s) from which the
Legend has been removed, or which were originally issued without the Legend,
pursuant to an effective registration statement and to deliver a prospectus in
connection with such sale or in compliance with an exemption from the
registration requirements of the Securities Act. In the event the Legend is
removed from any Security or any Security is issued without the Legend and
thereafter the effectiveness of a registration statement covering the resale of
such Security is suspended or a supplement or amendment thereto is required by
applicable securities laws, then upon reasonable advance notice to each
Purchaser holding such Security, the Company may require that the Legend be
placed on any such Security that cannot then be sold pursuant to an effective
registration statement or Rule 144 or with respect to which the opinion referred
to in clause (b) next above has not been rendered, which Legend shall be removed
when such Security may be sold pursuant to an effective registration statement
or Rule 144 or such holder provides the opinion with respect thereto described
in clause (b) next above.

     5.2. Transfer Agent Instructions. The Company shall instruct its transfer
          ---------------------------
agent to issue certificates, registered in the name of the Purchaser or its
nominee, for the Conversion Shares and Exercise Shares in accordance with the
terms of the Series B Stock and New Warrant, as applicable. Such certificates
shall bear a legend only in the form of the Legend and only to the extent
permitted by Section 5.1 above. The Company warrants that no instruction other
than such instructions referred to in this Article V, and no stop transfer
instructions other than stop transfer instructions to give effect to Section 2.2
hereof in the case of the Conversion Shares prior to registration under the
Securities Act, will be given by the Company to its transfer agent and, subject
to applicable law, the Securities shall otherwise be freely transferable on the
books and records of the Company. Nothing in this Section shall affect in any
way the Purchaser=s obligations and agreement set forth in Section 5.1 hereof to
resell the Securities pursuant to an effective registration statement and to
deliver a prospectus in connection with such sale or in compliance with an
exemption from the registration requirements of applicable securities laws.
Without limiting any other rights of the Purchaser or obligations of the
Company, if (i) the Purchaser provides the Company with an opinion of counsel,
to the effect that the Securities to be sold or transferred may be sold or
transferred pursuant to an exemption from registration or (ii) the Purchaser
transfers Securities pursuant to Rule 144, the Company shall permit the
transfer, and, in the case of Conversion Shares

                                       8

promptly instruct its transfer agent to issue one or more certificates in such
name and in such denomination as specified by the Purchaser in order to effect
such a transfer or sale.

          (b)  Purchaser shall exercise its right to convert the Series B Stock
by faxing an executed and completed Form of Notice of Conversion to the Company,

Date: August 29, 2001

                                 VOXWARE, INC.
                         COMMON STOCK PURCHASE WARRANT

     THIS CERTIFIES THAT, for value received, CASTLE CREEK TECHNOLOGY PARTNERS
LLC or its registered assigns (the "Holder"), is entitled to purchase from
VOXWARE, INC., a corporation organized under the laws of the State of Delaware
(the "Company"), at any time or from time to time during the period specified in
Section 2 hereof, Two Million One Hundred Forty-Two Thousand (2,142,000) fully
paid and nonassessable shares of the Company's common stock, par value $.001 per

                                       1
<PAGE>

     1.   Manner of Exercise; Issuance of Exercise Shares. Subject to the
          -----------------------------------------------
provisions hereof, including, without limitation, the limitations contained in
Sections 2 and 8 hereof, this Warrant may be exercised by the Holder hereof, in
whole or in part, by the surrender of this Warrant, together with a completed
exercise agreement in the form attached hereto (the "Exercise Agreement"), to
the Company during normal business hours on any business day at the Company's
principal executive offices (or such other office or agency of the Company as it
may designate by notice to the Holder hereof), and upon payment of the Exercise
Price to the Company in cash, by certified or official bank check or by wire
transfer to the account of the Company. The Exercise Shares so purchased shall
be deemed to be issued to the Holder hereof or such Holder's designee, as the
record owner of such shares, as of the close of business on the date on which
this Warrant shall have been surrendered, the completed Exercise Agreement shall
have been delivered, and payment shall have been made for such Exercise Shares
as set forth above or, if such date is not a business date, on the next
succeeding business day. The Exercise Shares so purchased shall be delivered to
the Holder hereof within a reasonable time, not exceeding two (2) Trading Days,
after this Warrant shall have been so exercised (the "Delivery Period").

     2.   Period of Exercise. This Warrant shall be exercisable at any time and
          ------------------
from time to time during the period from the date of initial issuance of this
Warrant (the "Issue Date") until 5:00 p.m. New York City time April 19, 2002
(the "Expiration Date"). The period beginning on the Issue Date and ending on
the Expiration Date is referred to herein as the "Exercise Period."

     3.   Mandatory Exercise.
          -------------------

          (a)  On no more than three (3) occasions during the Exercise Period
(each a "Mandatory Exercise Date"), the Company may, at its sole discretion, but
subject to satisfaction (or waiver) of all of the conditions set forth in
Section 3(c) hereof, require the Holder to exercise this Warrant in accordance
with the terms set forth below (a "Mandatory Exercise"). No Mandatory Exercise
may occur prior to the date (the "Effective Date") on which the registration
statement (the Registration Statement") that is required to be filed pursuant to
Section 2.1 of the Registration Rights Agreement dated as of April 19, 2001
between the Company and the Holder (the "Registration Rights Agreement") is
declared effective by the Securities Exchange Commission ("SEC"). The initial
Mandatory Exercise may not occur until the Holder has sold at least ninety-five
percent (95%) of the shares of Common Stock acquired by it pursuant to the
Securities Purchase Agreement dated as of April 19, 2001 between the Company and
the Holder (the "Securities Purchase Agreement"). The second and third Mandatory
Exercises may not occur until the Holder has sold at least ninety-five percent
(95%) of the shares of Common Stock acquired by it pursuant to the preceding
Mandatory Exercise. The Holder shall give written notice (a "Sale Notice") to
the Company within three (3) Trading Days after it has sold at least ninety-five
percent (95%) of the Common Stock acquired by it pursuant to the Securities
Purchase Agreement or the first two Mandatory Exercises, as applicable. No
Mandatory Exercise shall occur earlier than the first Trading Day of the
calendar month immediately following the calendar month in which the applicable
Sale Notice was given.

                                       2
<PAGE>

          (b)  In order to cause a Mandatory Exercise, the Company must first
deliver to the Holder, on the date that is five (5) Trading Days prior to the
applicable Mandatory Exercise Date, a written notice (the "Mandatory Exercise
Notice"). The Mandatory Exercise Notice shall set forth the Mandatory Exercise
Date to which it relates and the number of shares of Common Stock to be subject
to the Mandatory Exercise (subject to the limitations set forth in Section 3(e)
below) and shall state that, as of the date of such Mandatory Exercise Notice
(the "Mandatory Exercise Notice Date"), all conditions to such Mandatory
Exercise have been met. On each Mandatory Exercise Date, the Company shall issue
to the Holder the number of Exercise Shares specified in the applicable
Mandatory Exercise Notice (subject to the limitations set forth in Section 3(e)
below) and the Holder shall pay the Exercise Price (determined in accordance
with Section 3(d) below) in cash, by certified check or official bank check or
by wire transfer to the account of the Company.

          (c)  The Holder's obligation to purchase the Exercise Shares pursuant
to a Mandatory Exercise is conditioned upon the satisfaction by the Company (or
waiver by the Holder) of each of the following events:

               (i)   the Company shall have purchased contemporaneously with the
Mandatory Exercise (which purchase is in compliance with applicable Delaware
corporate law) for cash from the Holder (unless the Holder declines such
purchase in writing) at the Per Share Price a number of shares of the Company's
Series B Convertible Preferred Stock (the "Series B Shares") equal to: (A)
twenty percent (20%) of the aggregate Exercise Price to be paid upon the
applicable Mandatory Exercise Date, divided by (B) the Per Share Price. The "Per
Share Price" shall be equal to One Thousand Dollars ($1,000) plus accrued and
unpaid dividends through the date of payment on such Series B Share.

               (ii)  the Registration Statement shall have been available to the
Holder at all times from the Effective Date up to and including the Mandatory
Exercise Date for the resale of all Registrable Securities, as defined in the
Registration Rights Agreement;

               (iii) the representations and warranties of the Company set forth
in the Securities Purchase Agreement shall be true and correct in all material
respects as of the Mandatory Exercise Notice Date and the Mandatory Exercise
Date as if made on such dates;

               (iv)  the Company shall have complied with or performed in all
material respects all of the agreements, obligations and conditions set forth in
the Securities Purchase Agreement, the Registration Rights Agreement, the
Warrants, the Certificate of Designations (as defined in the Securities Purchase
Agreement) and all other agreements to which both the Company and the Holder are
parties that are required to be complied with or performed by the Company on or
before the Mandatory Exercise Date;

               (v)   the Company shall have delivered to the Holder on the
Mandatory Exercise Date a certificate, signed by an officer of the Company,
certifying that the conditions set forth in this Section 3(c) have been
fulfilled as of the Mandatory Exercise Notice Date and/or the Mandatory Exercise
Date, as applicable, it being understood that the Holder may rely on such
certificate as though it were a representation and warranty of the Company made
in the Securities Purchase Agreement and, in the event of any breach thereof,
shall be entitled to the

                                       3
<PAGE>

same remedies as may be available to the Holder in the event of a breach of any
such representation or warranty;

               (vi)   the Company shall have delivered to the Holder an opinion
of Counsel for the Company dated as of the Mandatory Exercise Date, in
substantially the form set forth on Exhibit A;

               (vii)  the Company shall have delivered to the Holder on the
Mandatory Exercise Date a duly executed certificate representing the number of
Exercise Shares determined in accordance with Sections 3(b) and 3(e);

               (viii) the Exercise Shares shall be included for quotation on the
OTC Bulletin Board or on a national securities exchange or on the Nasdaq Stock
Market and no suspension of trading in the Common Stock on such market shall
have occurred during the thirty (30) Trading Day period preceding the applicable
Mandatory Exercise Date;

               (ix)   the Company's revenues shall equal at least Five Hundred
Thousand Dollars ($500,000) ($375,000 for the quarter ended March 31, 2001) for
the last completed fiscal quarter for which such revenues have been publicly
announced by a press release or a filing with the SEC as of the applicable
Mandatory Exercise Notice Date.

               (x)    [Intentionally omitted]

               (xi)   there shall have been no Change in Control Transaction (as
defined in Section 4(d)(i) below).

          (d)  The Exercise Price for a Mandatory Exercise shall equal Eighty
Percent (80%) of the Market Price (as defined in Section 4(d)(ii) below) on the
applicable Mandatory Exercise Date.

          (e)  The number of shares of Common Stock subject to a Mandatory
Exercise shall not exceed the least of:

               (i)    a number of shares of Common Stock that would result in an
aggregate Exercise Price for any Mandatory Exercise equal to Five Hundred
Thousand Dollars ($500,000);

               (ii)   the number of unexercised Exercise Shares; and

               (iii)  the number of shares of Common Stock permitted to be
issued on the applicable Mandatory Exercise Date pursuant to Section 8 below.

or sale of securities, or any other voluntary action, avoid or seek to avoid the
observance or performance of any of the terms to be observed or performed by it
hereunder, but will at all times in good faith assist in the carrying out of all
the provisions of this Warrant and in the taking of all such action as may
reasonably be requested by the Holder of this Warrant in order to protect the
economic benefit inuring to the Holder hereof and the exercise privilege of the
Holder of this Warrant against dilution or other impairment, consistent with the
tenor and purpose of this Warrant.

          (b)  Consolidation; Merger. In case of any consolidation of the
               ---------------------
Company with, or merger of the Company into, any other corporation, or in case
of any sale or conveyance of all or substantially all of the assets of the
Company other than in connection with a plan of complete liquidation of the
Company at any time during the Exercise Period, then as a condition of such
consolidation, merger or sale or conveyance, adequate provision will be made
whereby the Holder hereof will have the right to acquire and receive upon
exercise of this Warrant in lieu of the Exercise Shares immediately theretofore
acquirable upon the exercise of this Warrant, such securities, cash or assets as
may be issued or payable with respect to or in exchange for the Exercise Shares
immediately theretofore acquirable and receivable upon exercise of this Warrant
had such consolidation, merger or sale or conveyance not taken place. In any
such case, the Company will make appropriate provision to insure that the
provisions of this Section 4 will thereafter be applicable as nearly as may be
in relation to any instrument or securities thereafter deliverable upon the
exercise of this Warrant.

          (c)  Notices. In case at any time:
               -------

               (i)   the Company shall declare any dividend upon the Common
Stock payable in shares of stock of any class or make any other distribution
(other than dividends or distributions payable in cash out of retained earnings
consistent with the Company's past practices with respect to declaring dividends
and making distributions) to the holders of the Common Stock;

               (ii)  the Company shall offer for subscription pro rata to the
holders of the Common Stock any additional shares of stock of any class or other
rights;

               (iii) there shall be any capital reorganization of the Company,
or reclassification of the Common Stock, or consolidation or merger of the
Company with or into, or sale of all or substantially all of its assets to,
another corporation or entity; or

               (iv)  there shall be a voluntary dissolution, liquidation or
winding-up of the Company;

then, in each such case, the Company shall give to the Holder of this Warrant
(a) notice of the date or estimated date on which the books of the Company shall
close or a record shall be taken for determining the holders of Common Stock
entitled to receive any such dividend, distribution, or subscription rights or
for determining the holders of Common Stock entitled to vote in respect of any
such reorganization, reclassification, consolidation,

                                       5
<PAGE>

merger, sale, dissolution, liquidation or winding-up and (b) in the case of any
such reorganization, reclassification, consolidation, merger, sale, dissolution,
liquidation or winding-up, notice of the date (or, if not then known, a
reasonable estimate thereof by the Company) when the same shall take place. Such
notice shall also specify the date on which the holders of Common Stock shall be
entitled to receive such dividend, distribution, or subscription rights or to
exchange their Common Stock for stock or other securities or property
deliverable upon such reorganization, reclassification, consolidation, merger,
sale, dissolution, liquidation, or winding-up, as the case may be. Such notice
shall be given at least thirty (30) days prior to the record date or the date on
which the Company's books are closed in respect thereto. Failure to give any
such notice or any defect therein shall not affect the validity of the
proceedings referred to in clauses (i), (ii), (iii) and (iv) above.
Notwithstanding the foregoing, the Company shall publicly disclose the substance
of any notice delivered hereunder prior to delivery of such notice to the Holder
hereof.

          (d)  Certain Definitions.
               -------------------

               (i)  A "Change in Control Transaction" will be deemed to have
occurred if (A) there occurs any consolidation, merger or other business

person (whether or not the Company is the surviving corporation), or any other
corporate reorganization or transaction or series of related transactions in
which in any of such events the voting stockholders of the Company prior to such
event cease to own 50% or more of the voting stock, or corresponding voting
equity interests, of the surviving corporation after such event (including
without limitation any "going private" transaction under Rule 13e-3 promulgated
pursuant to the Securities Exchange Act of 1934, as amended (the "Exchange
Act"), or tender offer by the Company under Rule 13e-4 promulgated pursuant to
the Exchange Act for twenty percent (20%) or more of the Company's Common
Stock), (B) any person (as defined in Section 13(d) of the Exchange Act),
together with its affiliates and associates (as such terms are defined in Rule
405 under the Securities Act), beneficially owns or is deemed to beneficially
own (as described in Rule 13d-3 under the Exchange Act without regard to the 60-
day exercise period) in excess of 50% of the Company's voting power, (C) there
is a replacement of more than one-half of the members of the Company's Board of
Directors which is not approved by those individuals who are members of the
Company's Board of Directors on the date thereof, or (D) in one or a series of
related transactions, there is a sale or transfer of all or substantially all of
the assets of the Company, determined on a consolidated basis, (E) the execution
by the Company of an agreement to which the Company is a party or by which it is
bound providing for an event set forth in (A), (B), (C) or (D) above, or
pursuant to which the Common Stock is to be converted or reclassified into other
securities, cash or property, or (F) the public announcement of a pending
transaction of the type set forth in (A), (B), (C) (D) or (E) above which has
not been abandoned or terminated.

               (ii) "Market Price," as of any date, means the average of three
lowest intra-day sale prices for the shares of Common Stock on the then
principal market for the Common Stock as reported by Bloomberg Financial Markets
("Bloomberg") during the period of ten consecutive Trading Days ending on the
Trading Day immediately preceding such date. Notwithstanding anything contained
in the foregoing, in no event shall the Market Price as of any date be greater
than the lowest intra-day bid price on the Trading Day immediately prior to such
date.

               -----------------------
the Holder hereof are transferable, in whole or in part, upon surrender of this
Warrant, together with a properly executed assignment in the form attached
hereto, at the office or agency of the Company referred to in Section 5(e)
below, provided, however, that any transfer or assignment shall be subject to

2.6 of the Securities Purchase Agreement. Until due presentment for registration
of transfer on the books of the Company, the Company may treat the registered
Holder hereof as the owner and Holder hereof for all purposes, and the Company
shall not be affected by any notice to the contrary. Notwithstanding anything to
the contrary contained herein, the registration rights described in Section 6
hereof are assignable only in accordance with the provisions of the Registration
Rights Agreement.

          (b)  Warrant Exchangeable for Different Denominations. This Warrant is
               ------------------------------------------------
exchangeable, upon the surrender hereof by the Holder hereof at the office or
agency of the Company referred to in Section 5(e) below, for new Warrants of
like tenor of different denominations representing in the aggregate the right to
purchase Exercise Shares, which may be purchased hereunder, each of such new
Warrants to represent the right to purchase Exercise Shares at the Exercise
Price therefor as shall be designated by the Holder hereof at the time of such
surrender.

          (c)  Replacement of Warrant. Upon receipt of evidence reasonably
               ----------------------
satisfactory to the Company of the loss, theft, destruction, or mutilation of
this Warrant and, in the case of any such loss, theft, or destruction, upon
delivery of an indemnity agreement reasonably satisfactory in form and amount to
the Company, or, in the case of any such mutilation, upon surrender and
cancellation of this Warrant, the Company, at its expense, will execute and
deliver, in lieu thereof, a new Warrant of like tenor.

          (d)  Cancellation; Payment of Expenses. Upon the surrender of this
               ---------------------------------
Warrant in connection with any transfer, exchange, or replacement as provided in

Warrants pursuant to this Section 5. The Company shall indemnify and reimburse
the Holder of this Warrant for all losses and damages arising as a result of or
related to any breach of the terms of this Warrant, including costs and expenses
(including legal fees) incurred by such Holder in connection with the
enforcement of its rights hereunder.

          (e)  Warrant Register. The Company shall maintain, at its principal

the Company shall record the name and

name and address of each transferee and each prior owner of this Warrant.

          (f)  Transfer or Exchange Without Registration. If, at the time of the

surrender of this Warrant in connection with any transfer, or exchange of this
Warrant, this Warrant (or, in the case of any exercise, the Exercise Shares
issuable hereunder), shall not be registered under the Securities Act and under
applicable state securities or blue sky laws, the Company may require, as a
condition of allowing such transfer or exchange, (i) that the Holder or
transferee of this Warrant, as the case may be, furnish to the Company a written
opinion of counsel (which opinion shall be in form, substance and scope
customary for opinions of counsel in comparable transactions and reasonably
acceptable to the Company) to the effect that such transfer or exchange may be
made without registration under the Securities Act and under applicable state
securities or blue sky laws (the cost of which shall be borne by the Company if
the Company's counsel renders such an opinion), (ii) that the Holder or
transferee execute and deliver to the Company an investment letter in form and
substance acceptable to the Company and (iii) that the transferee be an
"accredited investor" as defined in Rule 501(a) promulgated under the Securities
Act; provided that no such opinion, letter, or status as an "accredited
investor" shall be required in connection with a transfer pursuant to Rule 144
under the Securities Act.

     6.   Registration Rights. The initial Holder of this Warrant (and certain
          -------------------
assignees thereof) is entitled to the benefit of such registration rights in
respect of the Exercise Shares as are set forth in the Registration Rights
Agreement, including the right to assign such rights to certain assignees, as
set forth therein.

     7.   Notices. Any notices required or permitted to be given under the terms

extent) that such exercise by the Holder or Mandatory Exercise would result in

inconvenient forum to the maintenance of such suit or proceeding. The Company
further agrees that service of process upon the Company mailed by certified or
registered mail shall be deemed in every respect effective service of process
upon the Company in any such suit or proceeding. Nothing herein shall affect the
Holder's right to serve process in any other manner permitted by law. The
Company agrees that a final non-appealable judgment in any such suit or
proceeding shall be conclusive and may be enforced in other jurisdictions by
suit on such judgment or in any other lawful manner.

     Re:  Voxware, Inc.

Ladies and Gentlemen:

     This opinion is being furnished pursuant to Section 3(c)(vi) of the Common
Stock Purchase Warrant dated as of August 29, 2001 (the "Warrant"), issued by
Voxware, Inc., a Delaware corporation (the "Company"), to Castle Creek
Technology Partners LLC, a Delaware limited liability company (the "Purchaser").
Capitalized terms used herein and not otherwise defined shall have the
respective meanings ascribed to them in the Warrant.

     We have acted as counsel to the Company in connection with the preparation,
execution and delivery of the Warrant. As such counsel, we have examined and are
familiar with and have relied upon the following documents:

     (a)  the Certificate of Incorporation and By-laws, each as amended to date,
          of the Company;

     (b)  a Certificate of the Secretary of State of the State of Delaware,
          dated [Date], attesting to the continued legal existence and corporate
          good standing of the Company in Delaware (the "Domestic Certificate");

     (c)  a Certificate of the Secretary of State of the State of New Jersey,
          dated [Date], attesting to the good standing and due qualification of
          the Company to transact business in New Jersey (the "Foreign
          Qualification Certificate");

     (d)  the Warrant;

     (e)  an Officer's Certificate from the Company, dated as of the date hereof
          (the "Officer's Certificate"), attesting to the Company's Certificate
          of Incorporation and By-laws, certain resolutions adopted by the Board
          of Directors of the Company, the incumbency of certain officers of the
          Company, and to certain other matters; and

     (f)  such other records of meetings, documents, instruments and
          certificates (including but not limited to certificates of public
          officials and officers of the Company) as we have considered necessary
          for purposes of this opinion.

     In our examination of the documents described above, we have assumed the
genuineness of all signatures, the legal capacity of all individual signatories,
the completeness of all corporate and stock records provided to us, the
authenticity of all documents submitted to us as originals, the conformity to
original documents of all documents submitted to us as copies, and the
authenticity of the originals of such latter documents.

     In rendering this opinion, we have relied, as to all questions of fact
material to this opinion, upon certificates of public officials and officers of
the Company and upon the representations and warranties made by the Company in
the Warrant. We have not attempted to verify independently such facts, although
nothing has come to our attention which has caused us to question the accuracy
of such certificates or representations and warranties.

     Any reference herein to "our knowledge," or to any matter "known to us",
"coming to our attention" or "of which we are aware", or any variation of any of
the foregoing shall mean the conscious awareness of the attorneys in this firm
who have rendered substantive attention to the transaction to which this opinion
relates (including the preparation of the Warrant and the transactions
contemplated thereby) of the existence or absence of any facts which would
contradict our opinions and statements set forth herein. We have not undertaken
any independent investigation to determine the existence or absence of such
facts, and no inference as to our knowledge of the existence or absence of such
facts should be drawn from the fact of our representation of the Company.
Without limiting the foregoing, we have not conducted a search of any electronic
databases or the dockets of any court, administrative or regulatory body, agency
or other filing office in any jurisdiction.

     For purposes of this opinion, we have assumed that the Warrant have been
duly authorized, executed and delivered by all parties thereto other than the
Company, and that all such other parties have all requisite power and authority
to effect the transactions contemplated by the Warrant. We have also assumed
that the Warrant is the valid and binding obligation of each party thereto other
than the Company and is enforceable against such other parties in accordance
with its terms. We do not render any opinion as to the application of any
federal or state law or regulation to the power, authority or compliance of any
party to the Warrant other than the Company.

     Our opinions set forth below are qualified to the extent that they may be
subject to or affected by (i) applicable bankruptcy, insolvency, reorganization,
moratorium, fraudulent conveyance or similar laws relating to or affecting the
rights of creditors generally, (ii) statutory or decisional law concerning
recourse by creditors to security in the absence of notice or hearing, (iii)
duties and standards imposed on creditors and parties to contracts, including,
without limitation, requirements of good faith, reasonableness and fair dealing,
and (iv) general equitable principles. We express no

opinion as to the availability of any equitable or specific performance remedy
upon any breach of any of the agreements as to which we are opining herein, or
any of the agreements, documents or obligations referred to therein, or to the
successful assertion of any equitable defenses, inasmuch as the availability of
such remedies or the success of any equitable defense may be subject to the
discretion of a court. We are expressing no opinion herein with respect to
compliance by the Company with state securities or "blue sky" laws, or with any
state or federal securities antifraud laws.

     We also express no opinion herein as to any provision of any agreement (a)
which may be deemed to or construed to waive any right of the Company, (b) to
the effect that rights and remedies are not exclusive, that every right or
remedy is cumulative and may be exercised in addition to or with any other right
or remedy and does not preclude recourse to one or more other rights or
remedies, (c) relating to the effect of invalidity or unenforceability of any
provision of the Warrant on the validity or enforceability of any other
provision thereof, (d) requiring the payment of penalties, consequential damages
or liquidated damages, (e) which is in violation of public policy, including,
without limitation, any provision relating to non-competition and non-
solicitation or relating to indemnification and contribution with respect to
securities law matters, (f) purporting to indemnify any person against his, her
or its own negligence or intentional misconduct, (g) which provides that the
terms of the Warrant may not be waived or modified except in writing or (h)
relating to choice of law or consent to jurisdiction.

     Our opinions expressed in paragraph 1 below, insofar as they relate to the
due organization, valid existence, due qualification and good standing of the
Company, are based solely on the Domestic Certificate and the Foreign
Qualification Certificate and are limited accordingly, and, as to such matters,
our opinions are rendered as of the respective dates of such certificates. We
express no opinion as to the tax good standing of the Company in any
jurisdiction.

     Our opinion expressed in paragraph 2 below as to the issued and outstanding
shares of capital stock of the Company and outstanding convertible securities,
warrants, options or other rights of the Company is based solely on information
received from the Company's transfer agent, which we assume to be complete and
accurate, and on the Officer's Certificate.

     For purposes of our opinions in paragraphs 5 and 6 below, we have relied
upon representations made by the Purchaser in Article II of the Securities
Purchase Agreement, dated as of April 19, 2001 (the "Agreement"), by and between
the Company and the Purchaser and have assumed (without any independent
investigation) the accuracy of such representations. For purposes of our
opinions in paragraphs 5 and 6 below, we have also assumed that in connection
with the offer and sale of securities to the Purchaser, neither the Company nor
any person acting on its behalf has engaged in any form of "general solicitation
or general advertising" within the meaning contemplated by Rule 502 (c) of
Regulation D.

     Our opinion in paragraph 7 below is based solely on the Officer's
Certificate and is rendered as of the date of such certificate.

     We are opining herein solely as to the state laws of the State of New
Jersey, the Delaware General Corporation Law statute and the federal laws of the
United States of America. To the extent that any other laws govern any of the
matters as to which we are opining below, we have assumed, with your permission
and without independent investigation, that such laws are identical to the state
laws of the State of New Jersey, and we express no opinion as to whether such
assumption is reasonable or correct. We note that the Warrant states that it is
governed by Delaware law.

     For purposes of our opinions rendered below, we have assumed that the facts
and law governing the future performance by the Company of its obligations under
the Warrant will be identical to the facts and law governing its performance on
the date of this opinion.

     Based upon and subject to the foregoing, we are of the opinion that:

     1.   The Company is a corporation duly organized, validly existing and in
          good standing under the laws of the State of Delaware and has all
          requisite corporate power and authority to conduct its business as it
          is, to our knowledge, currently conducted, to enter into and perform
          its obligations under the Warrant, and to carry out the transactions
          contemplated by the Warrant. The Company is duly qualified to do
          business and is in good standing in the State of New Jersey.

     2.   The authorized capital stock of the Company on the date hereof
          consists of (i) [______________] shares of Common Stock, $.001 par
          value per share (the "Common Stock"), and (ii) [__________] shares of
          Preferred Stock, $.001 par value per share, of which [_______] shares
          have been designated as Series B Convertible Preferred Stock (the
          "Series B Stock"). As of the date hereof, without giving effect to the
          transactions contemplated by the Agreement, there are (i)
          [___________] shares of Common Stock of record issued and outstanding
          and (ii) [_________] shares of Series B Stock of record issued and
          outstanding. To our knowledge, there are no outstanding convertible
          securities, warrants, options or other rights to acquire any stock of
          the Company, or to acquire any such convertible securities, warrants,
          options or other rights, except for (i) the Purchased Securities and
          convertible securities, warrants, options or other rights listed on
          Schedule A hereto. [To be updated at time of delivery]. The delivery
          of certificates for the Exercise Shares to the Purchaser, pursuant to
          the exercise of the Warrant, are not subject to any preemptive rights
          arising under the Delaware General Corporation Law statute or set
          forth in the Certificate of Incorporation or By-laws of the Company
          or, to our knowledge, any other preemptive right, right of first
          refusal or other similar right created under any contract to which the
          Company is a party which rights have not been waived.

     3.   The issuance and delivery by the Company of the Exercise Shares and
          the repurchase of shares pursuant to Section 3(c)(i) of the Warrant
<PAGE>

Castle Creek Technology Partners LLC
[Date]
Page 5

          have been duly authorized by all necessary corporate action on the
          part of the Company. When issued in accordance with the provisions of
          the Warrant, the Exercise Shares will be duly and validly issued,
          fully paid and non-assessable.

     4.   Except for applicable blue sky filings and as may be required to
          register the Exercise Shares pursuant to the Registration Rights
          Agreement, no authorizations or approvals of, and no filings with any
          governmental or regulatory authority are necessary or required for the
          issuance and delivery of the Exercise Shares and the repurchase of
          shares pursuant to Section 3(c)(i) of the Warrant.

     5.   The issuance and delivery by the Company of the Exercise Shares and
          the repurchase of shares pursuant to Section 3(c)(i) of the Warrant do
          not (a) violate the provisions of any U.S. federal or New Jersey state
          law, rule or regulation applicable to the Company or the Delaware
          General Corporation Law statute; (b) violate the provisions of the
          Company's Certificate of Incorporation or By-laws, each as amended to
          date; (c) violate any judgment, decree, order or award of any court,
          governmental body or arbitrator specifically naming the Company of
          which we are aware; or (d) with or without notice and/or the passage
          of time, conflict with or result in the breach or termination of any
          term or provision of, or constitute a default under, or cause any
          acceleration under, or cause the creation of any lien, charge or
          encumbrance upon the properties or assets of the Company pursuant to,
          any agreement to which the Company is a party and which is listed as
          an Exhibit to the Company's [SEC Documents][To be updated to most
          recent SEC Documents prior to delivery].

     6.   Based in part on the representations of each of the Purchaser in
          Article II of the Agreement, the offer, issuance and sale of the
          Exercise Shares pursuant to the Warrant are exempt from registration
          under the Securities Act of 1933, as amended.

     7.   To our knowledge, except as identified on Schedule B hereto, there is
          no action, proceeding or litigation pending or threatened against the
          Company before any court, governmental or administrative agency or
          body.

     This opinion is provided to the Purchaser as a legal opinion only and not
as a guaranty or warranty of the matters discussed herein. This opinion is based
upon currently existing statutes, rules, regulations and judicial decisions and
is rendered as of the date hereof, and we disclaim any obligation to advise you
of any change in any of the foregoing sources of law or subsequent developments
in law or changes in facts or circumstances which might affect any matters or
opinions set forth herein.

     This opinion is rendered only to the Purchaser and is solely for the
benefit of the Purchaser in connection with the transactions contemplated by the
Warrant. This opinion

     THIS CERTIFIES THAT, for value received, CASTLE CREEK TECHNOLOGY PARTNERS

                                       1
<PAGE>

     1.  Manner of Exercise; Issuance of Exercise Shares.  Subject to the
         -----------------------------------------------
provisions hereof, including, without limitation, the limitations contained in
Sections 2 and 8 hereof, this Warrant may be exercised by the Holder hereof, in
whole or in part, by the surrender of this Warrant, together with a completed
exercise agreement in the form attached hereto (the "Exercise Agreement"), to
the Company during normal business hours on any business day at the Company's
principal executive offices (or such other office or agency of the Company as it
may designate by notice to the Holder hereof), and upon  payment  of the
Exercise Price to the Company in cash, by certified or official bank check or by
wire transfer to the account of the Company.  The Exercise Shares so purchased
shall be deemed to be issued to the Holder hereof or such Holder's designee, as
the record owner of such shares, as of the close of business on the date on
which this Warrant shall have been surrendered, the completed Exercise Agreement
shall have been delivered, and payment shall have been made for such Exercise
Shares as set forth above or, if such date is not a business date, on the next
succeeding business day.  The Exercise Shares so purchased shall be delivered to
the Holder hereof within a reasonable time, not exceeding two (2) Trading Days,
after this Warrant shall have been so exercised (the "Delivery Period").

     2.  Period of Exercise.  This Warrant shall be exercisable at any time and
         ------------------
from time to time during the period from the date of initial issuance of this
Warrant (the "Issue Date") until 5:00 p.m. New York City time on August 28, 2011

     3.  Intentionally Omitted.
         ----------------------

     4.  Certain Agreements of the Company.  The Company hereby covenants and
         ---------------------------------
agrees as follows:

         (a)  Certain Actions Prohibited.  The Company will not, by amendment of
              --------------------------
its charter or through any reorganization, transfer of assets, consolidation,
merger, dissolution, issue or sale of securities, or any other voluntary action,
avoid or seek to avoid the observance or performance of any of the terms to be
observed or performed by it hereunder, but will at all times in good faith
assist in the carrying out of all the provisions of this Warrant and in the
taking of all such action as may reasonably be requested by the Holder of this
Warrant in order to protect the economic benefit inuring to the Holder hereof
and the exercise privilege of the Holder of this Warrant against dilution or
other impairment, consistent with the tenor and purpose of this Warrant.

         (b)  Consolidation; Merger. In case of any consolidation of the Company
              ---------------------
with, or merger of the Company into, any other corporation, or in case of any
sale or conveyance of all or substantially all of the assets of the Company
other than in connection with a plan of complete liquidation of the Company at
any time during the Exercise Period, then as a condition of such consolidation,
merger or sale or conveyance, adequate provision will be made whereby the Holder
hereof will have the right to acquire and receive upon exercise of this Warrant
in lieu of the Exercise Shares immediately theretofore acquirable upon the
exercise of this Warrant, such securities, cash or assets as may be issued or
payable with respect to or in exchange for the Exercise Shares immediately
theretofore acquirable and receivable upon exercise of this Warrant had such
consolidation, merger or sale or conveyance not taken place. In any such case,
the Company will

                                       2
<PAGE>

make appropriate provision to insure that the provisions of this Section 4 will
thereafter be applicable as nearly as may be in relation to any instrument or
securities thereafter deliverable upon the exercise of this Warrant.

         (c)  Notices.  In case at any time:
              -------

              (i)    the Company shall declare any dividend upon the Common
Stock payable in shares of stock of any class or make any other distribution
(other than dividends or distributions payable in cash out of retained earnings
consistent with the Company's past practices with respect to declaring dividends
and making distributions) to the holders of the Common Stock;

              (ii)   the Company shall offer for subscription pro rata to the
holders of the Common Stock any additional shares of stock of any class or other
rights;

              (iii)  there shall be any capital reorganization of the Company,
or reclassification of the Common Stock, or consolidation or merger of the
Company with or into, or sale of all or substantially all of its assets to,
another corporation or entity; or

              (iv)   there shall be a voluntary dissolution, liquidation or
winding-up of the Company;

then, in each such case, the Company shall give to the Holder of this Warrant
(a) notice of the date or estimated date on which the books of the Company shall
close or a record shall be taken for determining the holders of Common Stock
entitled to receive any such dividend, distribution, or subscription rights or
for determining the holders of Common Stock entitled to vote in respect of any
such reorganization, reclassification, consolidation, merger, sale, dissolution,
liquidation or winding-up and (b) in the case of any such reorganization,
reclassification, consolidation, merger, sale, dissolution, liquidation or
winding-up, notice of the date (or, if not then known, a reasonable estimate
thereof by the Company) when the same shall take place.  Such notice shall also
specify the date on which the holders of Common Stock shall be entitled to
receive such dividend, distribution, or subscription rights or to exchange their
Common Stock for stock or other securities or property deliverable upon such
reorganization, reclassification, consolidation, merger, sale, dissolution,
liquidation, or winding-up, as the case may be.  Such notice shall be given at
least thirty (30) days prior to the record date or the date on which the
Company's books are closed in respect thereto.  Failure to give any such notice
or any defect therein shall not affect the validity of the proceedings referred
to in clauses (i), (ii), (iii) and (iv) above.  Notwithstanding the foregoing,
the Company shall publicly disclose the substance of any notice delivered
hereunder prior to delivery of such notice to the Holder hereof.

              (d)    Definition. "Trading Day" means a day on which the
                     ----------
principal United States securities exchange or trading market where the Common
Stock is then listed or traded as reported by Bloomberg is open for trading.

the Holder hereof are transferable, in whole or in part, upon surrender of this
Warrant, together with a properly executed assignment in the form attached

registration of transfer on the books of the Company, the Company may treat the
registered Holder hereof as the owner and Holder hereof for all purposes, and
the Company shall not be affected by any notice to the contrary.
Notwithstanding anything to the contrary contained herein, the registration
rights described in Section 6 hereof are assignable only in accordance with the
provisions of the Registration Rights Agreement.

         (b)  Warrant Exchangeable for Different Denominations. This Warrant is
              ------------------------------------------------
exchangeable, upon the surrender hereof by the Holder hereof at the office or
agency of the Company referred to in Section 5(e) below, for new Warrants of
like tenor of different denominations representing in the aggregate the right to
purchase Exercise Shares, which may be purchased hereunder, each of such new
Warrants to represent the right to purchase Exercise Shares at the Exercise
Price therefor as shall be designated by the Holder hereof at the time of such
surrender.

         (c)  Replacement of Warrant.  Upon receipt of evidence reasonably
              ----------------------
satisfactory to the Company of the loss, theft, destruction, or mutilation of
this Warrant and, in the case of any such loss, theft, or destruction, upon
delivery of an indemnity agreement reasonably satisfactory in form and amount to
the Company, or, in the case of any such mutilation, upon surrender and
cancellation of this Warrant, the Company, at its expense, will execute and
deliver, in lieu thereof, a new Warrant of like tenor.

         (d)  Cancellation; Payment of Expenses.  Upon the surrender of this
              ---------------------------------
Warrant in connection with any transfer, exchange, or replacement as provided in
this Section 5, this Warrant shall be promptly canceled by the Company.  The
Company shall pay all issuance taxes (other than securities transfer taxes) and
charges payable in connection with the preparation, execution, and delivery of
Warrants pursuant to this Section 5.  The Company shall indemnify and reimburse
the Holder of this Warrant for all losses and damages arising as a result of or
related to any breach of the terms of this Warrant, including costs and expenses
(including legal fees) incurred by such Holder in connection with the
enforcement of its rights hereunder.

         (e)  Warrant Register.  The Company shall maintain, at its principal
              ----------------
executive offices (or such other office or agency of the Company as it may
designate by notice to the Holder hereof), a register for this Warrant, in which
the Company shall record the name and address of the person in whose name this
Warrant has been issued, as well as the name and address of each transferee and
each prior owner of this Warrant.

         (f)  Transfer or Exchange Without Registration. If, at the time of the
              -----------------------------------------
surrender of this Warrant in connection with any transfer, or exchange of this
Warrant, this Warrant (or, in the case of any exercise, the Exercise Shares
issuable hereunder), shall not be registered under the

<PAGE>

Securities Act and under applicable state securities or blue sky laws, the
Company may require, as a condition of allowing such transfer or exchange, (i)
that the Holder or transferee of this Warrant, as the case may be, furnish to
the Company a written opinion of counsel (which opinion shall be in form,
substance and scope customary for opinions of counsel in comparable transactions
and reasonably acceptable to the Company) to the effect that such transfer or
exchange may be made without registration under the Securities Act and under
applicable state securities or blue sky laws (the cost of which shall be borne
by the Company if the Company's counsel renders such an opinion), (ii) that the
Holder or transferee execute and deliver to the Company an investment letter in
form and substance acceptable to the Company and (iii) that the transferee be an
"accredited investor" as defined in Rule 501(a) promulgated under the Securities
Act; provided that no such opinion, letter, or status as an "accredited
investor" shall be required in connection with a transfer pursuant to Rule 144
under the Securities Act.

     6.   Registration Rights.  The initial Holder of this Warrant (and certain
          -------------------
assignees thereof) is entitled to the benefit of such registration rights in
respect of the Exercise Shares as are set forth in the Registration Rights
Agreement, including the right to assign such rights to certain assignees, as
set forth therein.

     8.   Additional Restriction on Exercise.  Notwithstanding anything to the
          ----------------------------------
contrary contained herein, this Warrant shall not be exercisable by the Holder
or subject to a Mandatory Exercise by the Company to the extent (but only to the
extent) that such exercise by the Holder or Mandatory Exercise would result in

     9.   Miscellaneous.
          -------------

          (a)  Amendments.  This Warrant and any provision hereof may only be

construed in accordance with the laws of the State of Delaware. The Company
irrevocably consents to the jurisdiction of the United States federal courts and
state courts located in the State of Delaware in any suit or proceeding based on
or arising under this Warrant and irrevocably agrees that all claims in respect
of such suit or proceeding may be determined in such courts. The Company
irrevocably waives any objection to the laying of venue and the defense of an
inconvenient forum to the maintenance of such suit or proceeding. The Company
further agrees that service of process upon the Company mailed by certified or
registered mail shall be deemed in every respect effective service of process
upon the Company in any such suit or proceeding.  Nothing herein shall affect
the Holder's right to serve process in any other manner permitted by law.  The
Company agrees that a final non-appealable judgment in any such suit or
proceeding shall be conclusive and may be enforced in other jurisdictions by
suit on such judgment or in any other lawful manner.

                  ----------------------------------------------------
Notes shall be issuable in registered form without coupons in denominations of
$1,000 principal amount and integral multiples thereof. Every Note shall be
dated the date of its authentication, and shall bear interest from the
applicable date and accrued interest shall be payable on each August 15 and
February 15 of each year, commencing February 15, 2002, as specified on the face
of the form of Note attached as Exhibit A hereto.
                                ---------

     Interest on the Notes shall be deemed to have commenced accruing on August
24, 2001.

     The person in whose name any Note (or its Predecessor Note) is registered
at the close of business on any record date with respect to any interest payment
date (including any Note that is converted after the record date and on or
before the interest payment date) shall be entitled to receive the interest
payable on such interest payment date notwithstanding the cancellation of such
Note upon any transfer, exchange or conversion subsequent to the record date and
on or prior to such interest payment date; provided that, in the case of any
                                           --------
Note, or portion thereof, called for redemption pursuant to Article III on a
redemption date, or repurchased by the Company pursuant to Article XVI on a
repurchase date, during the period from the close of business on the record date
to the close of business on the Business Day next preceding the following
interest payment date, interest shall not be paid to the person in whose name
the Note, or portion thereof, is registered on the close of business on such
record date, and the Company shall have no obligation to pay interest on such
Note or portion thereof except to the extent required to be paid upon such
redemption or repurchase in accordance with Article III or Article XVI.
Interest may, at the option of the Company, be paid by check mailed to the
address of such person on the Note registry; provided that, with respect to any
                                             --------
holder of Notes with an aggregate principal amount equal to or in excess of
$500,000, at the request of such holder in writing to the Company, interest on
such holder's Notes shall be paid by wire transfer in immediately available
funds to any bank located in the United States in accordance with the wire
transfer instruction supplied by such holder from time to time to the Trustee
and paying agent (if different from Trustee) at least two days prior to the
applicable record date.  The term "record date" with respect to any interest
payment date shall mean the August 1 or February 1 preceding said August 15 or
February 15, respectively.

     Interest on the Notes shall be computed on the basis of a 360-day year
comprised of twelve 30-day months.

     Any interest on any Note which is payable, but is not punctually paid or
duly provided for, on any said August 15 or February 15 (herein called
"Defaulted Interest") shall forthwith cease to be payable to the Noteholder on
the relevant record date by virtue of his having been such Noteholder; and such
Defaulted Interest shall be paid by the Company, at its election in each case,
as provided in clause (1) or (2) below:

                                      -8-
<PAGE>

          (1) The Company may elect to make payment of any Defaulted Interest to
     the persons in whose names the Notes (or their respective Predecessor
     Notes) 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 to be paid on each Note and the date of the
     payment (which shall be not less than twenty-five (25) days after the
     receipt by the Trustee of such notice, unless the Trustee shall consent to
     an earlier date), and at the same time the Company shall deposit with the
     Trustee an amount of money equal to the aggregate amount 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 fifteen (15) days and
     not less than ten (10) days prior to the date of the proposed payment and
     not less than ten (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 mailed, first-class
     postage prepaid, to each Noteholder as of such special record date at his
     address as it appears in the Note register, not less than ten (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 Notes (or their respective Predecessor Notes) were 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 in any
     other lawful manner not inconsistent with the requirements of any
     securities exchange or automated quotation system on which the Notes may be
     listed or designated for issuance, and upon such notice as may be required
     by such exchange or automated quotation system, 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.

     Section 2.4  Execution of Notes.  The Notes shall be signed in the name and
                  ------------------
on behalf of the Company by the facsimile signature of its President, its Chief
Executive Officer, any of its Executive or Senior Vice Presidents, or any of its
Vice Presidents (whether or not designated by a number or numbers or word or
words added before or after the title "Vice President") and attested by the
facsimile signature of its Chief Financial Officer, Treasurer or its Assistant
Treasurer, or Secretary or any of its Assistant Secretaries (which may be
printed, engraved or otherwise reproduced thereon, by facsimile or otherwise).
Only such Notes as shall bear thereon a certificate of authentication
substantially in the form set forth on the form of Note attached as Exhibit A
hereto, manually executed by the Trustee (or an authenticating agent appointed
by the Trustee as provided by Section 17.11), shall be entitled to the benefits
of this Indenture or be valid or obligatory for any purpose. Such certificate by
the Trustee (or such authenticating agent) upon any Note executed by

                                      -9-
<PAGE>

the Company shall be conclusive evidence that the Note so authenticated has been
duly authenticated and delivered hereunder and that the holder thereof is
entitled to the benefits of this Indenture.

     In case any officer of the Company who shall have signed any of the Notes
shall cease to be such officer before the Notes so signed shall have been
authenticated and delivered by the Trustee, or disposed of by the Company, such
Notes nevertheless may be authenticated and delivered or disposed of as though
the person who signed such Notes had not ceased to be such officer of the
Company; and any Note may be signed on behalf of the Company by such persons as,
at the actual date of the execution of such Note, shall be the proper officers
of the Company, although at the date of the execution of this Indenture any such
person was not such an officer.

     Section 2.5  Exchange and Registration of Transfer of Notes; Restrictions
                  ------------------------------------------------------------
on Transfer.
-----------

          (a)  The Company shall cause to be kept at the Corporate Trust Office
     a register (the register maintained in such office and in any other office
     or agency of the Company designated pursuant to Section 5.2 being herein
     sometimes collectively referred to as the "Note register") in which,
     subject to such reasonable regulations as it may prescribe, the Company
     shall provide for the registration of Notes and of transfers of Notes. Such
     register shall be in written form or in any form capable of being converted
     into written form within a reasonable period of time. The Trustee is hereby
     appointed "Note registrar" for the purpose of registering Notes and
     transfers of Notes as herein provided. The Company may appoint one or more
     co-registrars in accordance with Section 5.2.

          Upon surrender for registration of transfer of any Note to the Note
     registrar or any co-registrar, and satisfaction of the requirements for
     such transfer set forth in this Section 2.5, the Company shall execute, and
     the Trustee shall authenticate and deliver, in the name of the designated
     transferee or transferees, one or more new Notes of any authorized
     denominations and of a like aggregate principal amount and bearing such
     restrictive legends as may be required by this Indenture.

          Notes may be exchanged for other Notes of any authorized denominations
     and of a like aggregate principal amount, upon surrender of the Notes to be
     exchanged at any office or agency maintained or designated pursuant to
     Section 5.2 for such purpose.  Whenever any Notes are so surrendered for
     exchange, the Company shall execute, and the Trustee shall authenticate and
     deliver, the Notes which the Noteholder making the exchange is entitled to
     receive, bearing registration numbers not contemporaneously outstanding.

          All Notes presented or surrendered for registration of transfer or for
     exchange shall (if so required by the Company, the Trustee, the Note
     registrar or any co-registrar) be duly endorsed, or be accompanied by a
     written instrument or instruments of transfer in form satisfactory to the
     Company and duly executed, by the Noteholder thereof or his attorney-in-
     fact duly authorized in writing.

                                      -10-

          Prior and as a condition to any sale or transfer of a Note or the
     Common Stock issued upon conversion thereof that bears the restrictive
     legend set forth in Section 2.5(b) or Section 2.5(c), respectively (other
     than pursuant to a registration statement that has been declared effective
     under the Securities Act), such transferee shall, unless the Company
     otherwise agrees in writing and so notifies the Trustee, furnish to the
     Company and the Trustee a signed letter containing representations and
     agreements relating to restrictions on transfer substantially in the form
     set forth in Exhibit B to this Indenture and an opinion of counsel if the
                  ---------
     Company so requests (other than with respect to a transfer pursuant to an
     effective registration statement under the Securities Act) and such
     certificates and other information as the Company and/or the Trustee
     reasonably may require to confirm that any such transfer is being made
     pursuant to an exemption from, or in a transaction not subject to, the
     registration requirements of the Securities Act.  If such sale or transfer
     of a Note or the Common Stock issued upon conversion thereof that bears the
     restrictive legend set forth in Section 2.5(b) or Section 2.5(c),
     respectively, is made pursuant to a registration statement that has been
     declared effective under the Securities Act, such transferor shall deliver
     a broker's letter or other evidence satisfactory to the Trustee and the
     Company as to compliance with the prospectus delivery requirements under
     the Securities Act.

          No service charge shall be charged to the Noteholder for any exchange
     or registration of transfer of Notes, but the Company may require payment
     of a sum sufficient to cover any tax, assessments or other governmental
     charges that may be imposed in connection therewith.

          None of the Company, the Trustee, the Note registrar or any co-
     registrar shall be required to exchange or register a transfer of (a) any
     Notes for a period of fifteen (15) days next preceding the mailing of the
     notice of redemption or (b) any Notes called for redemption or, if a
     portion of any Note is selected or called for redemption, such portion
     thereof selected or called for redemption or (c) any Notes surrendered for
     conversion or, if a portion of any Note is surrendered for conversion, such
     portion thereof surrendered for conversion or (d) any Notes, or a portion
     of any Note, surrendered for repurchase (and not withdrawn) in connection
     with a Repurchase Event.

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

          (b)  Every Note that bears or is required under this Section 2.5(b) to
     bear the legend set forth in this Section 2.5(b) (together with any Common
     Stock issued upon conversion of the Notes and required to bear the legend
     set forth in Section 2.5(c), collectively, the "Restricted Securities")
     shall be subject to the restrictions on transfer set forth in this Section
     2.5(b) (including the legend set forth below), unless such restrictions on
     transfer shall be waived by written consent of the Company, and the holder
     of each such Restricted Security, by such holder's acceptance thereof,
     agrees to be bound by all such

                                      -11-

     restrictions on transfer. As used in Sections 2.5(b) and 2.5(c), the term
     "transfer" encompasses any sale, pledge, transfer or other disposition
     whatsoever of any Restricted Security.

          Until two (2) years after the original issuance date of any Note, any
     certificate evidencing such Note (and all securities issued in exchange
     therefor or substitution thereof, other than Common Stock, if any, issued
     upon conversion thereof which shall bear the legend set forth in Section
     2.5(c), if applicable) shall bear a legend in substantially the following
     form (unless such Note has been transferred pursuant to a registration
     statement that has been declared effective under the Securities Act (and
     which continues to be effective at the time of such transfer), or the Note
     has been transferred pursuant to the exemption from registration provided
     by Rule 144 under the Securities Act, or unless otherwise agreed by the
     Company in writing, with notice thereof to the Trustee):

     sales thereof under Rule 144(k) under the Securities Act (or any successor
     rule), is purchased or owned by the Company or any Affiliate thereof may
     not be resold by the Company or such Affiliate unless registered under the
     Securities Act or resold pursuant to an exemption from the registration
     requirements of the Securities Act in a transaction that results in such
     Notes or Common Stock, as the case may be, no longer being "restricted
     securities" (as defined under Rule 144).

          (e)  Notwithstanding any provision of Section 2.5 to the contrary, in
     the event Rule 144(k) as promulgated under the Securities Act (or any
     successor rule) is amended to change the two-year period under Rule 144(k)
     (or the corresponding period under any successor rule), from and after
     receipt by the Trustee of the Officer's Certificate and Opinion of Counsel
     provided for in this Section 2.5(e), (i) each reference in Section 2.5(b)
     to "two (2) years" shall be deemed for all purposes hereof to be references
     to such changed period, (ii) each reference in Section 2.5(c) to "two (2)
     years" shall be deemed for all purposes hereof to be references to such
     changed period and (iii) all corresponding references in the Notes

                                      -16-
<PAGE>

     shall be deemed for all purposes hereof to be references to such changed
     period, provided that such changes shall not become effective if they are
     otherwise prohibited by, or would otherwise cause a violation of, the then-
     applicable federal securities laws. As soon as practicable after the
     Company has knowledge of the effectiveness of any such amendment to change
     the two-year period under Rule 144(k) (or the corresponding period under
     any successor rule), unless such changes would otherwise be prohibited by,
     or would otherwise cause a violation of, the then-applicable securities
     law, the Company shall provide to the Trustee an Officer's Certificate and
     Opinion of Counsel informing the Trustee of the effectiveness of such
     amendment and the effectiveness of the foregoing changes to Sections 2.5(b)
     and 2.5(c) and the Notes. The provisions of this Section 2.5(e) will not be
     effective until such time as the Opinion of Counsel and Officer's
     Certificate have been received by the Trustee hereunder. This Section
     2.5(e) shall apply to successive amendments to Rule 144(k) (or any
     successor rule) changing the holding period thereunder.

          (f)  The Trustee shall have no obligation or duty to monitor,
     determine or inquire as to compliance with any restrictions on transfer
     imposed under this Indenture or under applicable law with respect to any
     transfer of any interest in any Note other than to require delivery of such
     certificates and other documentation or evidence as are expressly required
     by, and to do so if and when expressly required by the terms of, this
     Indenture, and to examine the same to determine substantial compliance as
     to form with the express requirements hereof.

     Section 2.6  Mutilated, Destroyed, Lost or Stolen Notes.  In case any Note
                  ------------------------------------------
shall become mutilated or be destroyed, lost or stolen, the Company in its
discretion may execute, and upon its request the Trustee or an authenticating
agent appointed by the Trustee shall authenticate and deliver, a new Note,
bearing a number not contemporaneously outstanding, in exchange and substitution
for the mutilated Note, or in lieu of and in substitution for the Note so
destroyed, lost or stolen. In every case the applicant for a substituted Note
shall furnish to the Company, to the Trustee and, if applicable, to such
authenticating agent such security or indemnity as required by them to save each
of them harmless for any loss, liability, cost or expense caused by or connected
with such substitution, and, in every case of destruction, loss or theft, the
applicant shall also furnish to the Company, to the Trustee and, if applicable,
to such authenticating agent evidence to their satisfaction of the destruction,
loss or theft of such Note and of the ownership thereof.

     The Trustee or such authenticating agent may authenticate any such
substituted Note and deliver the same upon the receipt of such security or
indemnity as the Trustee, the Company and, if applicable, such authenticating
agent may require.  Upon the issuance of any substituted Note, 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 connected
therewith.  In case any Note which has matured or is about to mature or has been
called for redemption or is about to be converted into Common Stock shall become
mutilated or be destroyed, lost or stolen, the Company may, instead of issuing a
substitute Note, pay or authorize the payment of or convert or authorize the
conversion of the same (without surrender thereof except in the case of a
mutilated Note), as the case

                                      -17-
<PAGE>

may be, if the applicant for such payment or conversion shall furnish to the
Company, to the Trustee and, if applicable, to such authenticating agent such
security or indemnity as will be required by them to save each of them harmless
for any loss, liability, cost or expense caused by or connected with such
substitution, and, in case of destruction, loss or theft, evidence satisfactory
to the Company, the Trustee and, if applicable, any paying agent or conversion
agent of the destruction, loss or theft of such Note and of the ownership
thereof.

     Every substitute Note issued pursuant to the provisions of this Section 2.6
by virtue of the fact that any Note is destroyed, lost or stolen shall
constitute an additional contractual obligation of the Company, whether or not
the destroyed, lost or stolen Note shall be found at any time, and shall be
entitled to all the benefits of (but shall be subject to all the limitations set
forth in) this Indenture equally and proportionately with any and all other
Notes duly issued hereunder.  To the extent permitted by law, all Notes shall be
held and owned upon the express condition that the foregoing provisions are
exclusive with respect to the replacement or payment or conversion of mutilated,
destroyed, lost or stolen Notes and shall preclude any and all other rights or
remedies notwithstanding any law or statute existing or hereafter enacted to the
contrary with respect to the replacement or payment or conversion of negotiable
instruments or other securities without their surrender.

     Section 2.7  Temporary Notes.  Pending the preparation of definitive Notes,
                  ---------------
the Company may execute and the Trustee or an authenticating agent appointed by
the Trustee shall, upon written request of the Company, authenticate and deliver
temporary Notes (printed or lithographed). Temporary Notes shall be issuable in
any authorized denomination, and substantially in the form of the definitive
Notes but with such omissions, insertions and variations as may be appropriate
for temporary Notes, all as may be determined by the Company. Every such
temporary Note shall be executed by the Company and authenticated by the Trustee
or such authenticating agent upon the same conditions and in substantially the
same manner, and with the same effect, as the definitive Notes. Without
unreasonable delay the Company will execute and deliver to the Trustee or such
authenticating agent definitive Notes and thereupon any or all temporary Notes
may be surrendered in exchange therefor, at each office or agency maintained by
the Company pursuant to Section 5.2 and the Trustee or such authenticating agent
shall authenticate and deliver in exchange for such temporary Notes an equal
aggregate principal amount of definitive Notes. Such exchange shall be made by
the Company at its own expense and without any charge therefor. Until so
exchanged, the temporary Notes shall in all respects be entitled to the same
benefits and subject to the same limitations under this Indenture as definitive
Notes authenticated and delivered hereunder.

     Section 2.8  Cancellation of Notes Paid, Etc.  All Notes surrendered for
                  -------------------------------
the purpose of payment, redemption, repurchase, conversion, exchange or
registration of transfer, shall, if surrendered to the Company or any paying
agent or any Note registrar or any conversion agent, be surrendered to the
Trustee and promptly canceled by it, or, if surrendered to the Trustee, shall be
promptly canceled by it, and no Notes shall be issued in lieu thereof except as
expressly permitted by any of the provisions of this Indenture. Upon written
instructions of the Company, the Trustee shall dispose of canceled Notes in
accordance with its customary procedures. If the Company shall

                                      -18-
<PAGE>

acquire any of the Notes, such acquisition shall not operate as a redemption or
satisfaction of the indebtedness represented by such Notes unless and until the
same are delivered to the Trustee for cancellation.

     Section 2.9  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 Notes or as contained in
any notice of a redemption and that reliance may be placed only on the other
identification numbers printed on the Notes, and any such redemption shall not
be affected by any defect in or omission of such numbers. The Company will
promptly notify the Trustee of any change in the "CUSIP" numbers.

                                  ARTICLE III

                        PROVISIONAL REDEMPTION OF NOTES

     Section 3.1  Redemption Price.  The Company may, at its option, redeem all
                  ----------------
or any part of the Notes on any date prior to maturity, upon notice as set forth
in Section 3.2, and at a redemption price equal to $1,000 per $1,000 principal
amount of the Notes to be redeemed, plus accrued and unpaid interest, if any,
to, but excluding, the date of redemption, provided, however, that, prior to
                                           --------  -------
August 28, 2004, the Company shall only have such right of redemption if (1) the
Closing Price (as defined in Section 15.5(h)) per share of the Common Stock has
exceeded 200% of the Conversion Price then in effect (not including the effect
of any adjustment to the Conversion Price made pursuant to Section 15.11) for at
least twenty (20) Trading Days (as defined in Section 15.5(h)) within a period
of thirty (30) consecutive Trading Days (the "Determination Period") and (2)
within ten (10) days following the Determination Period, the Company mails to
holders the notice required pursuant to Section 3.2 (the date of such notice,
the "Notice Date"), and provided further that prior to the last date on which
                        -------- -------
the shelf registration statement (the "Shelf Registration Statement")
contemplated by the Registration Rights Agreement covering resales of the Notes
and the Common Stock issuable upon conversion of the Notes is required to remain
effective pursuant to the Registration Rights Agreement, such Shelf Registration
Statement is effective and available for use at all times during the period
beginning thirty (30) days prior to the Notice Date and ending on the earlier of
the redemption date or the last date on which the Shelf Registration Statement
is required to remain effective and available pursuant to the Registration
Rights Agreement, and is expected to remain effective and available for use
until the earlier of thirty (30) days following the redemption date or the last
date on which the Shelf Registration Statement is required to remain effective
pursuant to the Registration Rights Agreement. If the Company exercises such
right of redemption prior to August 28, 2002, the Company shall make an
additional payment in cash to holders of the redeemed Notes with respect to the
Notes called for redemption, in an amount (the "Provisional Payment") equal to
$70 per each $1,000 principal amount of the Note, less the amount of any
interest actually paid on such Notes prior to the date of notice of redemption
is mailed. The Company shall

                                      -19-
<PAGE>

make this additional payment on all Notes called for redemption prior to August
28, 2002, including any Notes converted after the date the notice of redemption
is mailed and before the provisional redemption date.

     Section 3.2  Notice of Redemption; Selection of Notes.  In case the Company
                  ----------------------------------------
shall desire to exercise the right to redeem all or, as the case may be, any
part of the Notes pursuant to Section 3.1, it shall fix a date for redemption,
and it, or at its request (which must be received by the Trustee at least ten
(10) Business Days prior to the date the Trustee is requested to give notice as
described below unless a shorter period is agreed to by the Trustee), the
Trustee in the name of and at the expense of the Company, shall mail or cause to
be mailed a notice of such redemption at least sixty (60) and not more than
ninety (90) days prior to the date fixed for redemption to the holders of Notes
so to be redeemed as a whole or in part at their last addresses as the same
appear on the Note register (provided that if the Company shall give such
                             --------
notice, it shall also give such notice, and notice of the Notes to be redeemed,
to the Trustee). Such mailing shall be by first class mail. The notice if mailed
in the manner herein provided shall be conclusively presumed to have been duly
given, whether or not the holder receives such notice. In any case, failure to
give such notice by mail or any defect in the notice to the holder of any Note
designated for redemption as a whole or in part shall not affect the validity of
the proceedings for the redemption of any other Note.

     Each such notice of redemption shall specify the aggregate principal amount
of Notes to be redeemed, the "CUSIP" number or numbers of such Notes, if any,
the date fixed for redemption, the redemption price at which Notes are to be
redeemed, the amount of the Provisional Payment, if any, the place or places of
payment, that payment will be made upon presentation and surrender of such
Notes, that interest accrued to, but excluding, the date fixed for redemption
will be paid as specified in said notice, and that on and after said date
interest thereon or on the portion thereof to be redeemed will cease to accrue.
Such notice shall also state the current Conversion Price and the date on which
the right to convert such Notes or portions thereof into Common Stock will
expire.  If fewer than all the Notes are to be redeemed, the notice of
redemption shall identify the Notes to be redeemed.  In case any Note is to be
redeemed in part only, the notice of redemption shall state the portion of the
principal amount thereof to be redeemed and shall state that on and after the
date fixed for redemption, upon surrender of such Note, a new Note or Notes in
principal amount equal to the unredeemed portion thereof will be issued.

     On or prior to the redemption date specified in the notice of redemption
given as provided in this Section, the Company will deposit with the Trustee or
with one or more paying agents (or, if the Company is acting as its own paying
agent, set aside, segregate and hold in trust as provided in Section 5.4) an
amount of money sufficient to redeem on the redemption date all the Notes (or
portions thereof) so called for redemption (other than those theretofore
surrendered for conversion into Common Stock) at the appropriate redemption
price, together with accrued interest to, but excluding, the date fixed for
redemption; provided that if such payment is made on the redemption date it must
            --------
be received by the Trustee or paying agent, as the case may be, by 10:00 a.m.
New York City time, on such date.  If any Note called for redemption is
converted pursuant hereto, any money deposited with the Trustee or any paying
agent or so segregated and held in trust for the redemption

                                      -20-
<PAGE>

of such Note, including the Provisional Payment, if any, shall be paid to the
Company upon its request, or, if then held by the Company shall be discharged
from such trust.

     If fewer than all the Notes are to be redeemed, the Company will give the
Trustee written notice in the form of an Officer's Certificate not fewer than
twenty-five (25) days (or such shorter period of time as may be acceptable to
the Trustee) prior to the redemption date as to the aggregate principal amount
of Notes to be redeemed.  If fewer than all the Notes are to be redeemed, the
Trustee shall select the Notes or portions thereof to be redeemed (in principal
amounts of $1,000 or integral multiples thereof), on a pro rata basis, or by a
method the Trustee considers fair and appropriate (as long as such method is not
prohibited by the rules of any United States national securities exchange or of
an established automated over-the-counter trading market in the United States on
which the Notes are then listed).  If any Note selected for partial redemption
is converted in part after such selection, the converted portion of such Note
shall be deemed (so far as is possible) to be the portion to be selected for
redemption.  The Notes (or portions thereof) so selected shall be deemed duly
selected for redemption for all purposes hereof, notwithstanding that any such
Note is converted as a whole or in part before the mailing of the notice of
redemption.

     Upon any redemption of less than all Notes, the Company and the Trustee may
(but need not) treat as outstanding any Notes surrendered for conversion during
the period of fifteen (15) days next preceding the mailing of a notice of
redemption and may (but need not) treat as not outstanding any Note
authenticated and delivered during such period in exchange for the unconverted
portion of any Note converted in part during such period.

     Section 3.3  Payment of Notes Called for Redemption.  If notice of
                  --------------------------------------
redemption has been given as above provided, the Notes or portion of Notes with
respect to which such notice has been given shall, unless converted into Common
Stock pursuant to the terms hereof, become due and payable on the date and at
the place or places stated in such notice at the applicable redemption price,
together with the Provisional Payment, if any, and interest accrued to, but
excluding, the date fixed for redemption, and on and after said date (unless the
Company shall default in the payment of such Notes at the redemption price,
together with the Provisional Payment, if any, and interest accrued to, but
excluding, said date) interest on the Notes or portion of Notes so called for
redemption shall cease to accrue and such Notes shall cease after the close of
business on the Business Day next preceding the date fixed for redemption to be
convertible into Common Stock and, except as provided in Sections 8.5 and 13.4,
to be entitled to any benefit or security under this Indenture, and the holders
thereof shall have no right in respect of such Notes except the right to receive
the redemption price thereof and unpaid interest to, but excluding, the date
fixed for redemption. On presentation and surrender of such Notes at a place of
payment specified in said notice, the said Notes or the specified portions
thereof to be redeemed shall be paid and redeemed by the Company at the
applicable redemption price, together with the Provisional Payment, if any, and
interest accrued thereon to, but excluding, the date fixed for redemption;
provided that, if the applicable redemption date is an interest payment date,
--------
the semi-annual payment of interest becoming due on such date shall be payable
to the holders of such Notes registered as such on the relevant record date
subject to the terms and provisions of Section 2.3 hereof.

                                      -21-
<PAGE>

     Upon presentation of any Note redeemed in part only, the Company shall
execute and the Trustee shall authenticate and deliver to the holder thereof, at
the expense of the Company, a new Note or Notes, of authorized denominations, in
principal amount equal to the unredeemed portion of the Notes so presented.

     Notwithstanding the foregoing, the Trustee shall not redeem any Notes or
mail any notice of optional redemption during the continuance of a default in
payment of interest or premium on the Notes or of any Event of Default of which,
in the case of any Event of Default other than under Section 7.1(a), (b) or (e),
a Responsible Officer of the Trustee has actual knowledge.  If any Note called
for redemption shall not be so paid upon surrender thereof for redemption, the
principal and premium, if any, shall, until paid or duly provided for, bear
interest from the date fixed for redemption at the rate borne by the Note and
such Note shall remain convertible into Common Stock until the principal and
premium, if any, shall have been paid or duly provided for.

     Section 3.4  Conversion Arrangement on Call for Redemption.  In connection
                  ---------------------------------------------
with any redemption of Notes, the Company may arrange for the purchase and
conversion of any Notes not converted prior to the expiration of such conversion
right by an agreement with one or more investment bankers or other purchasers to
purchase such Notes by paying to the Trustee in trust for the Noteholders, on or
before the date fixed for redemption, an amount not less than the applicable
redemption price, together with the Provisional Payment, if any, and interest
accrued to the date fixed for redemption, of such Notes. Notwithstanding
anything to the contrary contained in this Article III, the obligation of the
Company to pay the redemption price of such Notes, together with the Provisional
Payment, if any, and interest accrued to, but excluding, the date fixed for
redemption, shall be deemed to be satisfied and discharged to the extent such
amount is so paid by such purchasers. If such an agreement is entered into, a
copy of which, certified as true and correct by the Secretary or Assistant
Secretary of the Company will be filed with the Trustee prior to the date fixed
for redemption, any Notes not duly surrendered for conversion by the holders
thereof may, at the option of the Company, be deemed, to the fullest extent
permitted by law, acquired by such purchasers from such holders and
(notwithstanding anything to the contrary contained in Article XV) surrendered
by such purchasers for conversion, all as of immediately prior to the close of
business on the date fixed for redemption (and the right to convert any such
Notes shall be deemed to have been extended through such time), subject to
payment of the above amount as aforesaid. At the direction of the Company, the
Trustee shall hold and dispose of any such amount paid to it in the same manner
as it would monies deposited with it by the Company for the redemption of Notes.
Without the Trustee's prior written consent, no arrangement between the Company
and such purchasers for the purchase and conversion of any Notes shall increase
or otherwise affect any of the powers, duties, responsibilities or obligations
of the Trustee as set forth in this Indenture, and the Company agrees to
indemnify the Trustee from, and hold it harmless against, any loss, liability or
expense arising out of or in connection with any such arrangement for the
purchase and conversion of any Notes between the Company and such purchasers,
including the costs and expenses incurred by the Trustee in the defense of any
claim or liability arising out of or in connection with the exercise or
performance of any of its powers, duties, responsibilities or obligations under
this Indenture.

                      PARTICULAR COVENANTS OF THE COMPANY

     Section 5.1  Payment of Principal, Premium and Interest.  The Company
                  ------------------------------------------
covenants and agrees that it will duly and punctually pay or cause to be paid
the principal of and premium, if any, and interest on each of the Notes at the
places, at the respective times and in the manner provided herein and in the
Notes. Liquidated damages paid pursuant to Section 15.2 hereof, if any, shall be
paid within ten (10) Business Days of the date from which such liquidated
damages accrued pursuant to Section 15.2. Liquidated Damages on the Notes paid
pursuant to Section 3(e) of the Registration Rights Agreement, if any, shall be
paid at the times and in the manner provided therein. Each installment of
interest on the Notes due on any semi-annual interest payment date may be paid
by mailing checks for the interest payable to or upon the written order of the
holders of Notes entitled thereto as they shall appear on the registry books of
the Company, provided that, with respect to any holder of Notes with an
aggregate principal amount equal to or in excess of $500,000, at the request of
such holder in writing to the Company, interest on such holder's Notes shall be
paid by wire transfer in immediately available funds in accordance with the wire
transfer instructions supplied by such holder from time to time to the Trustee
and paying agent (if different from Trustee) at least two days prior to the
applicable record date.

     Section 5.2  Maintenance of Office or Agency.  The Company will maintain in
                  -------------------------------
the Borough of Manhattan, The City of New York, an office or agency where the
Notes may be presented for registration of transfer or exchange or for
presentation for payment or for conversion, redemption or repurchase and where
notices and demands to or upon the Company in respect of the Notes 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 not designated or appointed by the Trustee. 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 or the
office or agency of the Trustee in the Borough of Manhattan, The City of New
York.

     The Company may also from time to time designate one or more other offices
or agencies where the Notes may be presented or surrendered for any or all such
purposes and may from time to time rescind such designations; provided that no
                                                              --------
such designation or rescission shall in any manner relieve the Company of its
obligation to maintain an office or agency in the Borough of Manhattan, The City
of New York, 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.

                                      -23-

     The Company hereby initially designates the Trustee as paying agent, Note
registrar and conversion agent and the Corporate Trust Office and the office or
agency of the Trustee in the Borough of Manhattan, The City of New York (which
initially shall be The Bank of New York, located at 101 Barclay Street, Floor
21W, New York, New York 10286, Attention: Corporate Trust Administration, as one
such office or agency of the Company for each of the aforesaid purposes.

     So long as the Trustee is the Note registrar, the Trustee agrees to mail,
or cause to be mailed, the notices set forth in Section 8.10(a) and the third
paragraph of Section 8.11.

     Section 5.3  Appointments to Fill Vacancies in Trustee's Office.  The
                  --------------------------------------------------
Company, whenever necessary to avoid or fill a vacancy in the office of Trustee,
will appoint, in the manner provided in Section 8.10, a Trustee, so that there
shall at all times be a Trustee hereunder.

     Section 5.4  Provisions as to Paying Agent.
                  -----------------------------

             (a)  If the Company shall appoint a paying agent other than the
     Trustee or if the Trustee shall appoint such a paying agent, it will cause
     such paying agent to execute and deliver to the Trustee an instrument in
     which such agent shall agree with the Trustee, subject to the provisions of
     this Section 5.4:

                  (1)  that it will hold all sums held by it as such agent for
             the payment of the principal of and premium, if any, or interest
             (including Liquidated Damages, if any) on the Notes (whether such
             sums have been paid to it by the Company or by any other obligor on
             the Notes) in trust for the benefit of the holders of the Notes;

                  (2)  that it will give the Trustee notice of any failure by
             the Company (or by any other obligor on the Notes) to make any
             payment of the principal of and premium, if any, or interest
             (including Liquidated Damages, if any) on the Notes when the same
             shall be due and payable; and

                  (3)  that at any time during the continuance of an Event of
             Default, upon request of the Trustee, it will forthwith pay to the
             Trustee all sums so held in trust.

     official of it or any substantial part of its property, or shall consent to
     any such relief or to the appointment of or taking possession by any such
     official in an involuntary case or other proceeding commenced against it,
     or shall make a general assignment for the benefit of creditors, or shall

     bankruptcy, insolvency or other similar law now or hereafter in effect or
     seeking the appointment of a trustee, receiver, liquidator, custodian or
     other similar official of it or any substantial part of its property, and
     such involuntary case or other proceeding shall remain undismissed and
     unstayed for a period of ninety (90) consecutive days;

then, and in each and every such case (other than an Event of Default specified
in Section 7.1(i) or (j) with respect to the Company), unless the principal of
all of the Notes shall have already become due and payable, either the Trustee
or the holders of not less than 25% in aggregate principal amount of the Notes
then outstanding hereunder determined in accordance with Section 9.4, by notice
in writing to the Company (and to the Trustee if given by Noteholders), may
declare the principal of and premium, if any, on all the Notes and the interest
accrued thereon (including Liquidated Damages to the extent accrued and unpaid)
to be due and payable immediately, and upon any such declaration the same shall
become and shall be immediately due and payable, anything in this Indenture or
in the Notes contained to the contrary notwithstanding.  If an Event of Default
specified in Section 7.1(i) or (j) occurs and is continuing with respect to the
Company, the principal of all the Notes and the interest accrued thereon shall
be immediately due and payable.  Notwithstanding the foregoing if, at any time
after the principal of the Notes shall have been so declared due and payable,
and before any judgment or decree for the payment of the monies due shall have
been obtained or entered as hereinafter provided, the Company shall pay or shall
deposit with the Trustee a sum sufficient to pay all matured installments of
interest upon all Notes and the principal of and premium, if any, on any and all
Notes which shall have become due otherwise than by acceleration (with interest
on overdue installments of interest (to the extent that payment of such interest
is enforceable under applicable

nonpayment of principal of and premium, if any, and accrued interest on Notes
which shall have become due by acceleration, shall have been cured or waived
pursuant to Section 7.7, then and in every such case the holders of a majority
in aggregate principal amount of the Notes then outstanding, by written notice
to the Company and to the Trustee, may waive all defaults or Events of Default
and rescind and annul such declaration and its consequences; but no such waiver
or rescission and annulment shall extend to or shall affect any subsequent
default or Event of Default, or shall impair any right consequent thereon. The
Company shall notify the Responsible Officer of the Trustee, promptly upon
becoming aware thereof, of any default or Event of Default and shall deliver to
the Trustee a statement specifying such default or Event of Default and the
action the Company has taken, is taking or proposes to take with respect
thereto.

     In case the Trustee shall have proceeded to enforce any right under this
Indenture and such proceedings shall have been discontinued or abandoned because
of such waiver or rescission and annulment or for any other reason or shall have
been determined adversely to the Trustee, then and in every such case the
Company, the holders of Notes, and the Trustee shall be restored respectively to
their several positions and rights hereunder, and all rights, remedies and
powers of the Company, the holders of Notes, and the Trustee shall continue as
though no such proceeding had been instituted.

     Section 7.2  Payments of Notes on Default; Suit Therefor.  The Company
                  -------------------------------------------
covenants that (a) in case default shall be made in the payment by the Company
of any installment of interest upon any of the Notes as and when the same shall
become due and payable, and such default shall have continued for a period of
thirty (30) days, or (b) in case default shall be made in the payment of the
principal of or premium, if any, on any of the Notes as and when the same shall
have become due and payable, whether at maturity of the Notes or in connection
with any redemption or repurchase, by declaration under this Indenture or
otherwise, then, upon demand of the Trustee, the Company will pay to the
Trustee, for the benefit of the holders of the Notes, the whole amount that then
shall have become due and payable on all such Notes for principal and premium,
if any, or interest, or both, as the case may be, with interest upon the overdue
principal and premium, if any, and (to the extent that payment of such interest
is enforceable under applicable law) upon the overdue installments of interest
at the rate borne by the Notes; and, in addition thereto, such further amount as
shall be sufficient to cover the costs and expenses of collection, including
reasonable compensation to the Trustee, its agents, attorneys and counsel, and
any expenses or liabilities incurred by the Trustee hereunder other than through
its negligence or bad faith. Until such demand by the Trustee, the Company may
pay the principal of and premium, if any, and interest on the Notes to the
registered holders, whether or not the Notes are overdue.

     In case the Company shall fail forthwith to pay such amounts upon such
demand, the Trustee, in its own name and as trustee of an express trust, shall
be entitled and empowered to institute any actions or proceedings at law or in
equity for the collection of the sums so due and unpaid, and may prosecute any
such action or proceeding to judgment or final decree, and may enforce any such

                                      -31-
<PAGE>

judgment or final decree against the Company or any other obligor on the Notes
and collect in the manner provided by law out of the property of the Company or
any other obligor on the Notes wherever situated the monies adjudged or decreed
to be payable.

     In the case there shall be pending proceedings for the bankruptcy or for
the reorganization of the Company or any other obligor on the Notes under Title
11 of the United States Code, or any other applicable law, or in case a
receiver, assignee or trustee in bankruptcy or reorganization, liquidator,
sequestrator or similar official shall have been appointed for or taken
possession of the Company or such other obligor, the property of the Company or
such other obligor, or in the case of any other judicial proceedings relative to
the Company or such other obligor upon the Notes, or to the creditors or
property of the Company or such other obligor, the Trustee, irrespective of
whether the principal of the Notes shall then be due and payable as therein
expressed or by declaration or otherwise and irrespective of whether the Trustee
shall have made any demand pursuant to the provisions of this Section 7.2, shall
be entitled and empowered, by intervention in such proceedings or otherwise, to
file and prove a claim or claims for the whole amount of principal, premium, if
any, and interest (including Liquidated Damages, if any) owing and unpaid in
respect of the Notes, and, in case of any judicial proceedings, to file such
proofs of claim and other papers or documents and to take such other actions as
it may deem necessary or advisable in order to have the claims of the Trustee
and of the Noteholders allowed in such judicial proceedings relative to the
Company or any other obligor on the Notes, its or their creditors, or its or
their property, and to collect and receive any monies or other property payable
or deliverable on any such claims, and to distribute the same after the
deduction of any amounts due the Trustee under Section 8.6; and any receiver,
assignee or trustee in bankruptcy or reorganization, liquidator, custodian or
similar official is hereby authorized by each of the Noteholders 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 Noteholders, to pay to the Trustee any
amount due it for reasonable compensation, expenses, advances and disbursements,
including agents and counsel fees incurred by it up to the date of such
distribution.  To the extent that such payment of reasonable compensation,
expenses, advances and disbursements out of the estate in any such proceedings
shall be denied for any reason, payment of the same shall be secured by a lien
on, and shall be paid out of, any and all distributions, dividends, monies,
securities and other property which the holders of the Notes may be entitled to
receive in such proceedings, whether in liquidation or under any plan of
reorganization or arrangement or otherwise.

     All rights of action and of asserting claims under this Indenture, or under
any of the Notes, may be enforced by the Trustee without the possession of any
of the Notes, or the production thereof on any trial or other proceeding
relative thereto, and any such suit or 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 Notes.

     In any proceedings brought by the Trustee (and in any proceedings involving
the interpretation of any provision of this Indenture to which the Trustee

                                      -32-
<PAGE>

shall be a party) the Trustee shall be held to represent all the holders of the
Notes, and it shall not be necessary to make any holders of the Notes parties to
any such proceedings.

     Section 7.3  Application of Monies Collected by Trustee.  Any monies
                  ------------------------------------------
collected by the Trustee pursuant to this Article VII shall be applied in the
following order, at the date or dates fixed by the Trustee for the distribution
of such monies, upon presentation of the several Notes, and stamping thereon 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
     8.6;

          Second:  In case the principal of the outstanding Notes shall not have
     become due and be unpaid, to the payment of interest on the Notes in
     default in the order of the maturity of the installments of such interest,
     with interest (to the extent that such interest has been collected by the
     Trustee) upon the overdue installments of interest at the rate borne by the
     Notes, such payments to be made ratably to the persons entitled thereto;

          Third:  In case the principal of the outstanding Notes shall have
     become due, by declaration or otherwise, and be unpaid, to the payment of
     the whole amount then owing and unpaid upon the Notes for principal and
     premium, if any, and interest, with interest on the overdue principal and
     premium, if any, and (to the extent that such interest has been collected
     by the Trustee) upon overdue installments of interest at the rate borne by
     the Notes; and in case such monies shall be insufficient to pay in full the
     whole amounts so due and unpaid upon the Notes, then to the payment of such
     principal and premium, if any, and interest without preference or priority
     of principal and premium, if any, over interest, or of interest over
     principal and premium, if any, or of any installment of interest over any

     Section 7.4  Proceedings by Noteholder.  No holder of any Note shall have
                  -------------------------
any right by virtue of or by availing of any provision of this Indenture to
institute any suit, action or proceeding in equity or at law upon or under or
with respect to this Indenture, or for the appointment of a receiver, trustee,
liquidator, custodian or other similar official, or for any other remedy
hereunder, unless such holder previously shall have given to the Trustee written
notice of an Event of Default and of the continuance thereof, as hereinbefore
provided, and unless also the holders of not less than 25% in aggregate
principal amount of the Notes then outstanding shall have made written request
upon the Trustee to institute such action, suit or proceeding in its own name as
Trustee hereunder and shall have offered to the Trustee such indemnity as may be
reasonably satisfactory to the Trustee against the costs, expenses and
liabilities to be incurred therein or thereby, and the Trustee for sixty (60)
days after its receipt of such notice, request and offer of indemnity, shall
have neglected or refused to institute any such action, suit or proceeding and
no direction inconsistent with such written request shall have been given to the
Trustee pursuant to Section 7.7; it being understood and intended, and being
expressly covenanted by the taker and holder

                                      -33-
<PAGE>

of every Note with every other taker and holder and the Trustee, that no one or
more holders of Notes 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 holder of Notes, or to obtain or seek to
obtain priority over or preference to any other such holder, or to enforce any
right under this Indenture, except in the manner herein provided and for the
equal, ratable and common benefit of all holders of Notes (except as otherwise
provided herein). For the protection and enforcement of this Section 7.4, each
and every Noteholder and the Trustee shall be entitled to such relief as can be
given either at law or in equity.

     Notwithstanding any other provision of this Indenture and any provision of
any Note, the right of any holder of any Note to receive payment of the
principal of and premium, if any, and interest (including Liquidated Damages to
the extent accrued but unpaid) on such Note, on or after the respective due
dates expressed in such Note, or to institute suit for the enforcement of any
such payment on or after such respective dates against the Company shall not be
impaired or affected without the consent of such holder.

     Anything in this Indenture or the Notes to the contrary notwithstanding,
the holder of any Note, without the consent of either the Trustee or the holder
of any other Note, in his own behalf and for his own benefit, may enforce, and
may institute and maintain any proceeding suitable to enforce, his rights of
conversion as provided herein.

     Section 7.5  Proceedings by Trustee.  In case of an Event of Default the
                  ----------------------
Trustee may in its discretion proceed to protect and enforce the rights vested
in it by this Indenture by such appropriate judicial proceedings as the Trustee
shall deem most effectual to protect and enforce any of such rights, either by
suit in equity or by action at law or by proceeding in bankruptcy or otherwise,
whether for the specific enforcement of any covenant or agreement contained in
this Indenture or in aid of the exercise of any power granted in this Indenture,
or to enforce any other legal or equitable right vested in the Trustee by this
Indenture or by law.

     Section 7.6  Remedies Cumulative and Continuing.  Except as provided in the
                  ----------------------------------
last paragraph of Section 2.6, all powers and remedies given by this Article VII
to the Trustee or to the Noteholders shall, to the extent permitted by law, be
deemed cumulative and not exclusive of any thereof or of any other powers and
remedies available to the Trustee or the holders of the Notes, by judicial
proceedings or otherwise, to enforce the performance or observance of the
covenants and agreements contained in this Indenture, and no delay or omission
of the Trustee or of any holder of any of the Notes to exercise any right or
power accruing upon any default or Event of Default occurring and continuing as
aforesaid shall impair any such right or power, or shall be construed to be a
waiver of any such default or any acquiescence therein; and, subject to the
provisions of Section 7.4, every power and remedy given by this Article VII or
by law to the Trustee or to the Noteholders may be exercised from time to time,
and as often as shall be deemed expedient, by the Trustee or by the Noteholders.

     Section 7.7  Direction of Proceedings and Waiver of Defaults by Majority of
                  --------------------------------------------------------------
Noteholders.  The holders of a majority in aggregate principal amount of the
-----------
Notes at the time outstanding determined in accordance with Section 9.4 shall
have the right to direct the time, method, and place

                                      -34-
<PAGE>

of conducting any proceeding for any remedy available to the Trustee or
exercising any trust or power conferred on the Trustee; provided, however, that
                                                        --------  -------
(a) such direction shall not be in conflict with any rule of law or with this
Indenture, and (b) the Trustee may take any other action deemed proper by the
Trustee which is not inconsistent with such direction. The holders of not less
than a majority in aggregate principal amount of the Notes at the time
outstanding determined in accordance with Section 9.4 may on behalf of the
holders of all of the Notes waive any past default or Event of Default hereunder
and its consequences except (i) a default in the payment of interest or premium,
if any, on, or the principal of, the Notes when due, (ii) a failure by the
Company to convert any Notes into Common Stock or (iii) a default in respect of
a covenant or provisions hereof which under Article XI cannot be modified or
amended without the consent of all affected holders of Notes then outstanding.
Upon any such waiver the Company, the Trustee and the holders of the Notes shall
be restored to their former positions and rights hereunder; but no such waiver
shall extend to any subsequent or other default or Event of Default or impair
any right consequent thereon. Whenever any default or Event of Default hereunder
shall have been waived as permitted by this Section 7.7, said default or Event
of Default shall for all purposes of the Notes and this Indenture be deemed to
have been cured and to be not continuing; but no such waiver shall extend to any
subsequent or other default or Event of Default or impair any right consequent
thereon.

     Section 7.8  Notice of Defaults.  The Trustee shall, within ninety (90)
                  ------------------
days after the occurrence of a default, mail to all Noteholders, as the names
and addresses of such holders appear upon the Note register, notice of all
defaults actually known to a Responsible Officer, unless such defaults shall
have been cured or waived before the giving of such notice; and provided that,
except in the case of default in the payment of the principal of, or premium, if
any, or interest (including Liquidated Damages to the extent accrued but unpaid)
on any of the Notes, including without limiting the generality of the foregoing
any default in the payment of any Repurchase Price or in the payment of any
amount due in connection with any redemption of Notes, then in any such event
the Trustee shall be protected in withholding such notice if and so long as a
trust committee of directors and/or Responsible Officers of the Trustee in good
faith determine that the withholding of such notice is in the interests of the
Noteholders.

     Section 7.9  Undertaking to Pay Costs.  All parties to this Indenture
                  ------------------------
agree, and each holder of any Note by his acceptance thereof shall be deemed to
have agreed, that any court may, in its discretion, require, 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 or omitted by it as Trustee, the filing by any
party litigant in such suit of an undertaking to pay the costs of such suit and
that such court may in its discretion assess reasonable costs, including
reasonable attorneys' fees and expenses, against any party litigant in such
suit, having due regard to the merits and good faith of the claims or defenses
made by such party litigant; provided that the provisions of this Section 7.9
                             --------
shall not apply to any suit instituted by the Trustee, to any suit instituted by
any Noteholder, or group of Noteholders, holding in the aggregate more than 10%
in principal amount of the Notes at the time outstanding determined in
accordance with Section 9.4, or to any suit instituted by any Noteholder for the
enforcement of the payment of the principal of or premium, if any, or interest
(including Liquidated Damages to the extent accrued but unpaid) on any Note
(including, but not limited to, the redemption

                                      -35-
<PAGE>

price or repurchase price with respect to the Notes being redeemed or
repurchased as provided in this Indenture) on or after the due date expressed in
such Note or to any suit for the enforcement of the right to convert any Note in
accordance with the provisions of Article XV.

     Section 7.10  Delay or Omission Not Waiver.  No delay or omission of the
                   ----------------------------
Trustee or of any holder of any Note 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 any acquiescence therein. Every right and
remedy given by this Article or by law to the Trustee or to the holders of Notes
may be exercised from time to time, and as often as may be deemed expedient, by
the Trustee or by the holders of Notes, as the case may be.

                                 ARTICLE VIII

                             CONCERNING THE TRUSTEE

     Section 8.1  Duties and Responsibilities of Trustee.  The Trustee, prior to
                  --------------------------------------
the occurrence of an Event of Default and after the curing or waiver of all
Events of Default that may have occurred, undertakes to perform such duties and
only such duties as are specifically set forth in this Indenture. In case an
Event of Default has occurred (which has not been cured or waived) the Trustee
shall exercise such of the rights and powers vested in it by this Indenture, and
use the same degree of care and skill in their exercise, as a prudent person
would exercise or use under the circumstances in the conduct of such person's
own affairs.

     No provision of this Indenture shall be construed to relieve the Trustee
from liability for its own negligent action, its own negligent failure to act or
its own willful misconduct, except that

             (a)  prior to the occurrence of an Event of Default and after the
     curing or waiving of all Events of Default that may have occurred:

                  (1)  the duties and obligations of the Trustee shall be
     determined solely by the express provisions of this Indenture and, after it
     has been qualified thereunder, the Trust Indenture Act, and the Trustee
     shall not be liable except for the performance of such duties and
     obligations as are specifically set forth in this Indenture and no implied
     covenants or obligations shall be read into this Indenture and the Trust
     Indenture Act against the Trustee; and

                  (2)  in the absence of bad faith and willful misconduct on the
     part of the Trustee, the Trustee may conclusively rely, as to the truth of
     the statements and the correctness of the opinions expressed therein, upon
     any certificates or opinions furnished to the Trustee and conforming to the
     requirements of this Indenture; provided, however, in the case of any such
                                     --------  -------
     certificates or opinions that by any provisions hereof are specifically
     required to be furnished to the Trustee, the Trustee

                                      -36-
<PAGE>

     shall be under a duty to examine the same to determine whether or not they
     conform to the requirements of this Indenture;

             (b)  the Trustee shall not be liable for any error of judgment made
     in good faith by a Responsible Officer or Officers of the Trustee, unless
     it shall be proved that the Trustee was negligent in ascertaining the
     pertinent facts;

             (c)  the Trustee shall not be liable to any Noteholder with respect
     to any action taken or omitted to be taken by it in good faith in
     accordance with the direction of the holders of not less than a majority in
     principal amount of the Notes at the time outstanding determined as
     provided in Section 9.4 relating to the time, method and place of
     conducting any proceeding for any remedy available to the Trustee, or
     exercising any trust or power conferred upon the Trustee, under this
     Indenture; and

             (d)  whether or not therein 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.

          None of the provisions contained in this Indenture shall require the
Trustee to expend or risk its own funds or otherwise incur personal financial
liability in the performance of any of its duties or in the exercise of any of
its rights or powers, if there is reasonable ground for believing that the
repayment of such funds or adequate indemnity against such risk or liability is
not reasonably assured to it.

     Section 8.2  Reliance on Documents, Opinions, Etc.  Except as otherwise
                  ------------------------------------
provided in Section 8.1:

             (a)  the Trustee may conclusively rely and shall be protected in
     acting upon any resolution, certificate, statement, instrument, opinion,
     report, notice, request, consent, order, bond, note, coupon or other paper
     or document believed by it in good faith to be genuine and to have been
     signed or presented by the proper party or parties;

             (b)  any request, direction, order or demand of the Company
     mentioned herein shall be sufficiently evidenced by an Officer's
     Certificate (unless other evidence in respect thereof be herein
     specifically prescribed); and any resolution of the Board of Directors may
     be evidenced to the Trustee by a copy thereof certified by the Secretary or
     an Assistant Secretary of the Company;

             (c)  the Trustee may consult with counsel of its selection, and any
     advice of such counsel or Opinion of Counsel shall be full and complete
     authorization and protection in respect of any action taken or omitted by
     it hereunder in good faith and in accordance with such advice or Opinion of
     Counsel;

                                      -37-
<PAGE>

          (d) the Trustee shall be under no obligation to exercise any of the
     rights or powers vested in it by this Indenture at the request, order or
     direction of any of the Noteholders pursuant to the provisions of this
     Indenture, unless such Noteholders shall have offered to the Trustee
     reasonable security or indemnity reasonably satisfactory to it against the
     costs, expenses and liabilities which may be incurred therein or thereby;

          (e) 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 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 further inquiry or investigation, it shall be entitled to examine the
     books, records and premises of the Company, personally or by agent or
     attorney; provided, however, that if the payment within a reasonable time
     to the Trustee of the costs, expenses or liabilities likely to be incurred
     by it in the making of such investigation is, in the opinion of the
     Trustee, not reasonably assured to the Trustee by the security afforded to
     it by the terms of this Indenture, the Trustee may require indemnity
     reasonably satisfactory to the Trustee from the Noteholders against such
     expenses or liability as a condition to so proceeding; the reasonable
     expenses of every such examination shall be paid by the Company or, if paid
     by the Trustee or any predecessor Trustee, shall be repaid by the Company
     upon demand;

          (f) 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 by it with due
     care hereunder;

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

          (h) the Trustee shall not be deemed to have notice of any default or
     Event of Default unless a Responsible Officer of the Trustee has actual
     knowledge thereof or unless written notice of any event which is in fact
     such a default is received by the Trustee at the Corporate Trust Office of
     the Trustee, and such notice references the Notes and this Indenture; and

          (i) the rights, privileges, protections, immunities and benefits given
     to the Trustee, including, without limitation, its right to be indemnified,
     are extended to, and shall be enforceable by, the Trustee in each of its
     capacities hereunder, and to each agent, custodian and other Person
     employed to act hereunder.

In no event shall the Trustee be liable for any consequential loss or damage of
any kind whatsoever (including but not limited to lost profits), even if the
Trustee has been advised of the likelihood of

                                      -38-
<PAGE>

such loss or damage and regardless of the form of action other than through the
Trustee's willful misconduct or gross negligence.

     Section 8.3 No Responsibility for Recitals, Etc. The recitals contained
                 -----------------------------------
herein and in the Notes (except in the Trustee's certificate of authentication)
shall be taken as the statements of the Company, and the Trustee assumes no
responsibility for the correctness of the same. The Trustee makes no
representations as to the validity or sufficiency of this Indenture or of the
Notes. The Trustee shall not be accountable for the use or application by the
Company of any Notes or the proceeds of any Notes authenticated and delivered by
the Trustee in conformity with the provisions of this Indenture.

     Section 8.4  Trustee, Paying Agents, Conversion Agents or Registrar May Own
                  --------------------------------------------------------------
Notes.  The Trustee, any paying agent, any conversion agent or Note registrar,
-----
in its individual or any other capacity, may become the owner or pledgee of
Notes with the same rights it would have if it were not Trustee, paying agent,
conversion agent or Note registrar.

     Section 8.5 Monies to be Held in Trust. Subject to the provisions of
                 --------------------------
Section 13.4, all monies received by the Trustee shall, until used or applied as
herein provided, be held in trust for the purposes for which they were received.
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 may be
agreed in writing from time to time by the Company and the Trustee.

     Section 8.6 Compensation and Expenses of Trustee. The Company covenants and
                 ------------------------------------
agrees to pay to the Trustee from time to time, and the Trustee shall be
entitled to, such compensation as the Company and the Trustee shall from time to
time agree in writing for all services rendered by it hereunder in any capacity
(which shall not be limited by any provision of law in regard to the
compensation of a trustee of an express trust), and the Company will pay or
reimburse the Trustee upon its request for all reasonable expenses,
disbursements and advances reasonably incurred or made by the Trustee in
accordance with any of the provisions of this Indenture (including the
reasonable compensation and the expenses and disbursements of its agents and
counsel and of all persons not regularly in its employ) except any such expense,
disbursement or advance as may arise from its negligence, willful misconduct or
bad faith. The Company also covenants to indemnify the Trustee or any
predecessor Trustee in any capacity under this Indenture and its agents and any
authenticating agent for, and to hold them harmless against, any and all loss,
damages, claims, liability or expense incurred without negligence, willful
misconduct or bad faith on the part of the Trustee or such agent or
authenticating agent, as the case may be, and arising out of or in connection
with the acceptance or administration of this trust or in any other capacity
hereunder, including the costs and expenses of defending themselves against any
claim (whether asserted by the Company, a Holder or any other Person) of
liability in the premises. The obligations of the Company under this Section 8.6
to compensate or indemnify the Trustee and to pay or reimburse the Trustee for
expenses, disbursements and advances shall be secured by a lien upon all
property and funds held or collected by the Trustee as such, except, subject to
the effect of Sections 4.3 and 7.5, funds held in

                                      -39-
<PAGE>

trust herewith for the benefit of the holders of particular Notes prior to the
date of the accrual of such unpaid compensation or indemnifiable claim. The
obligation of the Company under this Section shall survive the satisfaction and
discharge of this Indenture. The indemnification provided in this Section 8.6
shall extend to the officers, directors, agents and employees of the Trustee.

     When the Trustee and its agents and any authenticating agent incur expenses
or render services after an Event of Default specified in Section 7.1(i) or (j)
occurs, the expenses and the compensation for the services are intended to
constitute expenses of administration under any bankruptcy, insolvency or
similar laws.

     Section 8.7 Officer's Certificate as Evidence. Except as otherwise provided
                 ---------------------------------
in Section 8.1, whenever in the administration of the provisions of this
Indenture the Trustee shall deem it necessary or desirable that a matter be
proved or established prior to taking or omitting any action hereunder, such
matter (unless other evidence in respect thereof be herein specifically
prescribed) may, in the absence of negligence, willful misconduct, recklessness
and bad faith on the part of the Trustee, be deemed to be conclusively proved
and established by an Officer's Certificate delivered to the Trustee, and such
Officer's Certificate, in the absence of negligence, willful misconduct,
recklessness and bad faith on the part of the Trustee, shall be full warrant to
the Trustee for any action taken or omitted by it under the provisions of this
Indenture upon the faith thereof.

     Section 8.8 Conflicting Interests of Trustee. After qualification under
                 --------------------------------
the Trust Indenture Act, 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.

     Section 8.9 Eligibility of Trustee. There shall at all times be a Trustee
                 ----------------------
hereunder that shall be a person that is eligible pursuant to the Trust
Indenture Act to act as such and has a combined capital and surplus (together
with its corporate parent) of at least $50,000,000. If such person publishes
reports of condition at least annually, pursuant to law or to the requirements
of any supervising or examining authority, then for the purposes of this
Section, 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 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 8.10  Resignation or Removal of Trustee.
              ---------------------------------

          (a) The Trustee may at any time resign by giving written notice of
     such resignation to the Company and by mailing notice thereof to the
     holders of Notes at their addresses as they shall appear on the Note
     register. Upon receiving such notice of resignation, the Company shall
     promptly appoint a successor trustee by written instrument, in duplicate,
     executed by order of the Board of Directors, one copy of which instrument
     shall be delivered to the resigning Trustee and one copy to the successor
     trustee. If no successor trustee shall have been so appointed and have
     accepted appointment sixty (60) days after the

                                      -40-
<PAGE>

     mailing of such notice of resignation to the Noteholders, the resigning
     Trustee may, at the expense of the Company, petition any court of competent
     jurisdiction for the appointment of a successor trustee, or any Noteholder
     who has been a bona fide holder of a Note or Notes for at least six months
     may, subject to the provisions of Section 7.9, on behalf of himself and all
     others similarly situated, petition any such court for the appointment of a
     successor trustee. Such court may thereupon, after such notice, if any, as
     it may deem proper and prescribe, appoint a successor trustee.

          (b) In case at any time any of the following shall occur:

                (1) the Trustee shall fail to comply with Section 8.8 within a
          reasonable time after written request therefor by the Company or by
          any Noteholder who has been a bona fide holder of a Note or Notes for
          at least six months, or

                (2) the Trustee shall cease to be eligible in accordance with
          the provisions of Section 8.9 and shall fail to resign after written
          request therefor by the Company or by any such Noteholder, 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, the Company may by a Board resolution remove the
     Trustee and appoint a successor trustee by written instrument, in
     duplicate, executed by order of the Board of Directors, one copy of which
     instrument shall be delivered to the Trustee so removed and one copy to the
     successor trustee, or, subject to the provisions of Section 7.9, any
     Noteholder who has been a bona fide holder of a Note or Notes 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
     and the appointment of a successor trustee.  Such court may thereupon,
     after such notice, if any, as it may deem proper and prescribe, remove the
     Trustee and appoint a successor trustee.

          (c) The holders of a majority in aggregate principal amount of the
     Notes at the time outstanding may at any time remove the Trustee and
     nominate a successor trustee which shall be deemed appointed as successor
     trustee unless within ten (10) days after notice to the Company of such
     nomination the Company objects thereto, in which case the Trustee so
     removed or any Noteholder, upon the terms and conditions and otherwise as
     in Section 8.10(a) provided, may, at the expense of the Company, petition
     any court of competent jurisdiction for an appointment of a successor
     trustee.

          (d) Any resignation or removal of the Trustee and appointment of a
     successor trustee pursuant to any of the provisions of this Section 8.10
     shall become effective upon acceptance of appointment by the successor
     trustee as provided in Section 8.11.

     Section 8.11 Acceptance by Successor Trustee. Any successor trustee
                  -------------------------------
appointed as provided in Section 8.10 shall execute, acknowledge and deliver to
the Company and to its predecessor trustee an instrument accepting such
appointment hereunder, and thereupon the resignation or removal of the
predecessor trustee shall become effective and such successor trustee, without
any further act, deed or conveyance, shall become vested with all the rights,
powers, duties and obligations of its predecessor hereunder, with like effect as
if originally named as trustee herein; but, nevertheless, on the written request
of the Company or of the successor trustee, the trustee ceasing to act shall,
upon payment of any amounts then due it pursuant to the provisions of Section
8.6, execute and deliver an instrument transferring to such successor trustee
all the rights and powers of the trustee so ceasing to act. Upon request of any
such successor trustee, the Company shall execute any and all instruments in
writing for more fully and certainly vesting in and confirming to such successor
trustee all such rights and powers. Any trustee ceasing to act shall,
nevertheless, retain a lien upon all property and funds held or collected by
such trustee as such, except for funds held in trust for the benefit of holders
of particular Notes, to secure any amounts then due it pursuant to the
provisions of Section 8.6.

     No successor trustee shall accept appointment as provided in this Section
8.11 unless at the time of such acceptance such successor trustee shall be
qualified under the provisions of Section 8.8 and be eligible under the
provisions of Section 8.9.

     Upon acceptance of appointment by a successor trustee as provided in this
Section 8.11, each of the Company and the former trustee shall mail or cause to
be mailed notice of the succession of such trustee hereunder to the holders of
Notes at their addresses as they shall appear on the Note register.  If the
Company fails to mail such notice within ten (10) days after acceptance of
appointment by the successor trustee, the successor trustee shall cause such
notice to be mailed at the expense of the Company.

     Section 8.12 Succession by Merger, Etc. Any corporation or other entity
                  -------------------------
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 or other
entity succeeding to all or substantially all of the corporate trust business of
the Trustee (including the trust created by this Indenture), shall be the
successor to the Trustee hereunder without the execution or filing of any paper
or any further act on the part of any of the parties hereto, provided that in
the case of any corporation succeeding to all or substantially all of the
corporate trust business of the Trustee such corporation shall be qualified
under the provisions of Section 8.8 and eligible under the provisions of Section
8.9.

     In case at the time such successor to the Trustee shall succeed to the
trusts created by this Indenture, any of the Notes shall have been authenticated
but not delivered, any such successor to the Trustee may adopt the certificate
of authentication of any predecessor trustee or authenticating agent appointed
by such predecessor trustee, and deliver such Notes so authenticated; and in
case at that time any of the Notes shall not have been authenticated, any
successor to the Trustee or an authenticating agent appointed by such successor
trustee may authenticate such Notes either in the

                                      -42-
<PAGE>

name of any predecessor trustee hereunder or in the name of the successor
trustee; and in all such cases such certificates shall have the full force which
it is anywhere in the Notes or in this Indenture provided that the certificate
of the Trustee shall have; provided, however, that the right to adopt the
certificate of authentication of any predecessor Trustee or to authenticate
Notes in the name of any predecessor Trustee shall apply only to its successor
or successors by merger, conversion or consolidation.

     Section 8.13 Limitation on Rights of Trustee as Creditor. If and when the
                  -------------------------------------------
Trustee shall be or become a creditor of the Company (or any other obligor upon
the Notes), after qualification under the Trust Indenture Act, the Trustee shall
be subject to the provisions of the Trust Indenture Act regarding the collection
of the claims against the Company (or any such other obligor).

                           CONCERNING THE NOTEHOLDERS

     Section 9.1 Action by Noteholders. Whenever in this Indenture it is
                 ---------------------
provided that the holders of a specified percentage in aggregate principal
amount of the Notes may take any action (including the making of any demand or
request, the giving of any notice, consent or waiver or the taking of any other
action), the fact that at the time of taking any such action, the holders of
such specified percentage have joined therein may be evidenced (a) by any
instrument or any number of instruments of similar tenor executed by Noteholders
in person or by agent or proxy appointed in writing, or (b) by the record of the
holders of Notes voting in favor thereof at any meeting of Noteholders duly
called and held in accordance with the provisions of Article X, or (c) by a
combination of such instrument or instruments and any such record of such a
meeting of Noteholders. Whenever the Company or the Trustee solicits the taking
of any action by the holders of the Notes, the Company or the Trustee may fix in
advance of such solicitation, a date as the record date for determining holders
entitled to take such action. The record date shall be not more than fifteen
(15) days prior to the date of commencement of solicitation of such action.

     Section 9.2 Proof of Execution by Noteholders. Subject to the provisions of
                 ---------------------------------
Sections 8.1, 8.2 and 10.5, proof of the execution of any instrument by a
Noteholder or his agent or proxy shall be sufficient if made in accordance with
such reasonable rules and regulations as may be prescribed by the Trustee or in
such manner as shall be satisfactory to the Trustee. The holding of Notes shall
be proved by the Note register or by a certificate of the Note registrar. The
record of any Noteholders' meeting shall be proved in the manner provided in
Section 10.6.

     Section 9.3 Who Are Deemed Absolute Owners. The Company, the Trustee, any
                 ------------------------------
authenticating agent, any paying agent, any conversion agent and any Note
registrar may deem the person in whose name such Note shall be registered upon
the Note register to be, and may treat him as, the absolute owner of such Note
(whether or not such Note shall be overdue and notwithstanding any notation of
ownership or other writing thereon) for the purpose of receiving payment of or
on account of the principal of, premium, if any, and interest (including
Liquidated Damages to the

                                      -43-
<PAGE>

extent accrued but unpaid) on such Note, for conversion of such Note and for all
other purposes; and neither the Company nor the Trustee nor any authenticating
agent nor any paying agent nor any conversion agent nor any Note registrar shall
be affected by any notice to the contrary. All such payments so made to any
holder for the time being, or upon his order, shall be valid, and, to the extent
of the sum or sums so paid, effectual to satisfy and discharge the liability for
monies payable upon any such Note.

     Section 9.4 Company-Owned Notes Disregarded. In determining whether the
                 -------------------------------
holders of the requisite aggregate principal amount of Notes have concurred in
any direction, consent, waiver or other action under this Indenture, Notes that
are owned by the Company or any other obligor on the Notes or by any person
directly or indirectly controlling or controlled by or under direct or indirect
common control with the Company or any other obligor on the Notes shall be
disregarded and deemed not to be outstanding for the purpose of any such
determination; provided that for the purposes of determining whether the Trustee
               --------
shall be protected in relying on any such direction, consent, waiver or other
action only Notes which a Responsible Officer actually knows are so owned shall
be so disregarded. Notes so owned which have been pledged in good faith may be
regarded as outstanding for the purposes of this Section 9.4 if the pledgee
shall establish to the satisfaction of the Trustee the pledgee's right to vote
such Notes and that the pledgee is not the Company, any other obligor on the
Notes or a person directly or indirectly controlling or controlled by or under
direct or indirect common control with the Company or any such other obligor. In
the case of a dispute as to such right, any decision by the Trustee taken upon
the advice of counsel shall be full protection to the Trustee. Upon request of
the Trustee, the Company shall furnish to the Trustee promptly an Officer's
Certificate listing and identifying all Notes, if any, known by the Company to
be owned or held by or for the account of any of the above described persons;
and, subject to Section 8.1, the Trustee shall be entitled to accept such
Officer's Certificate as conclusive evidence of the facts therein set forth and
of the fact that all Notes not listed therein are outstanding for the purpose of
any such determination.

     Section 9.5 Revocation of Consents; Future Holders Bound. At any time prior
                 --------------------------------------------
to (but not after) the evidencing to the Trustee, as provided in Section 9.1, of
the taking of any action by the holders of the percentage in aggregate principal
amount of the Notes specified in this Indenture in connection with such action,
any holder of a Note which is shown by the evidence to be included in the Notes
the holders of which have consented to such action may, by filing written notice
with the Trustee at its Corporate Trust Office and upon proof of holding as
provided in Section 9.2, revoke such action so far as concerns such Note. Except
as aforesaid, any such action taken by the holder of any Note shall be
conclusive and binding upon such holder and upon all future holders and owners
of such Note and of any Notes issued in exchange or substitution therefor,
irrespective of whether any notation in regard thereto is made upon such Note or
any Note issued in exchange or substitution therefor.

shall not, directly or indirectly, consolidate with or merge with or into any
other Person or sell, lease, convey or transfer all or substantially all its
assets, whether in a single transaction or a series of related transactions, to
any person or group of affiliated persons unless:

             (a)   either (i) in the case of a merger or consolidation that
does not involve a transfer of all or substantially all of the Company's
properties and assets, the Company is the surviving entity or (ii) in case the
Company shall consolidate with or merge into another person or sell, lease,
convey or transfer all or substantially all assets, whether in a single
transaction or a series of related transactions, to any person, the person
formed by such consolidation or into which the Company is merged, or the person
which acquires by sale, conveyance or transfer, or which leases the properties
and assets of the Company substantially as an entirety, shall be a corporation,
limited liability company, partnership or trust, shall be organized and validly
existing under the laws of the United States of America, any state thereof or
the District of Columbia and shall expressly assume, by an indenture
supplemental hereto, executed and delivered to the Trustee, in form satisfactory
to the Trustee, the due and punctual payment of the principal of, premium, if
any, and interest (including Liquidated Damages, if any) on all of the Notes as
applicable, and the performance or observance of every covenant of this
Indenture on the part of the Company to be performed or observed and shall have
provided for the applicable conversion rights set forth in Section 15.6 and the
repurchase rights set forth in Article XVI;

             (c)   the Company has delivered to the Trustee an Officer's
Certificate and an Opinion of Counsel, each stating that such consolidation,
merger, conveyance, transfer or lease and, if a supplemental indenture is
required in connection with such transaction, such supplemental indenture comply
with this Article and that all conditions precedent herein provided for relating
to such transaction have been complied with, together with any documents
required under Article IX.

     Section 12.2  Successor Entity to be Substituted. In case of any such
                   ----------------------------------
consolidation, merger, sale, conveyance or lease in accordance with Section
12.1, and, where required in accordance with Section 12.1(a) upon the assumption
by the successor entity, by supplemental indenture, executed and delivered to
the Trustee and satisfactory in form to the Trustee, of the due and punctual
payment of the principal of and premium, if any, and interest (including
Liquidated Damages, if any) on all of the Notes and the due and punctual
performance of all of the covenants and conditions of this Indenture to be
performed by the Company, such successor entity shall succeed to and be
substituted for the Company, with the same effect as if it had been named herein

signed, and may issue either in its own name or in the name of TiVo Inc. any or
all of the Notes issuable hereunder which theretofore shall not have been signed
by the Company and delivered to the Trustee; and, upon the order of such
successor entity instead of the Company and subject to all the terms, conditions
and limitations in this Indenture prescribed, the Trustee shall authenticate and
shall deliver, or cause to be authenticated and delivered, any Notes which
previously shall have been signed and delivered by the officers of the Company
to the Trustee for authentication, and any Notes which such successor entity
thereafter shall cause to be signed and delivered to the Trustee for that
purpose.  All the Notes so issued shall in all respects have the same legal rank
and benefit under this Indenture as the Notes theretofore or thereafter issued
in accordance with the terms of this Indenture as though all of such Notes had
been issued at the date of the execution hereof.  In the event of any such
consolidation, merger, sale, conveyance or lease, the person named as the
"Company" in the first paragraph of this Indenture or any successor which shall
thereafter have become such in the manner prescribed in this Article XII may be
dissolved, wound up and liquidated at any time thereafter and such person shall
be released from its liabilities as obligor and maker of the Notes and from its
obligations under this Indenture.

     In case of any such consolidation, merger, sale, conveyance or lease, such
changes in phraseology and form (but not in substance) may be made in the Notes
thereafter to be issued as may be appropriate.

     Section 12.3  Opinion of Counsel to be Given Trustee. The Trustee, subject
                   --------------------------------------

to the Trustee for cancellation all Notes theretofore authenticated (other than
any Notes that have been destroyed, lost or stolen and in lieu of or in
substitution for which other Notes shall have been authenticated and delivered)
and not theretofore canceled, or (b) all the Notes not theretofore canceled or
delivered to the Trustee for cancellation shall have become due and payable, or
are by their terms to become due and payable within one year or are to be called
for redemption within one year under arrangements satisfactory to the Trustee
for the giving of notice of redemption, and the Company shall deposit with the
Trustee, in trust, funds sufficient to pay at maturity or upon redemption of all
of the Notes (other than any Notes which shall have been mutilated, destroyed,
lost or stolen and in lieu of or in substitution for which other Notes shall
have been authenticated and delivered) not theretofore canceled or delivered to
the Trustee for cancellation, including principal and premium, if any, and
interest (including Liquidated Damages, if any) due or to become due to such
date of maturity or redemption date, as the case may be, and if in either case
the Company shall also pay or cause to be paid all other sums payable hereunder
by the Company, then this Indenture shall cease to be of further effect (except
as to (i) remaining rights of registration of transfer, substitution and
exchange and conversion of Notes, (ii) rights hereunder of Noteholders to
receive payments of principal of and premium, if any, and interest on, the Notes
and the other rights, duties and obligations of Noteholders, as beneficiaries
hereof with respect to the amounts, if any, so deposited with the Trustee and
(iii) the rights, obligations and immunities of the Trustee hereunder), and the
Trustee, on demand of the Company accompanied by an Officer's Certificate and an
Opinion of Counsel as required by Section 17.5 and at the cost and expense of
the Company, shall execute proper instruments acknowledging satisfaction of and
discharging this Indenture; the Company, however, hereby agreeing to reimburse
the Trustee for any costs or expenses thereafter reasonably and properly
incurred by the Trustee and to compensate the Trustee for any services
thereafter reasonably and properly rendered by the Trustee in connection with

shall be held in trust and applied by it to the payment, either directly or
through any paying agent (including the Company if acting as its own paying
agent), to the holders of the particular Notes for the payment or redemption of
which such monies have been deposited with the Trustee, of all sums due and to
become due thereon for principal and interest and premium, if any.

     Section 13.3  Paying Agent to Repay Monies Held. Upon the satisfaction and

discharge of this Indenture, all monies then held by any paying agent of the
Notes (other than the Trustee) shall, upon demand of the Company, be repaid to
it or paid to the Trustee, and thereupon such paying agent shall be released
from all further liability with respect to such monies.

applicable law, any monies deposited with or paid to the Trustee for payment of
the principal of, premium, if any, or interest on Notes and not applied but
remaining unclaimed by the holders of Notes for two years after the date upon
which the principal of, premium, if any, or interest (including Liquidated
Damages, if any) on such Notes, as the case may be, shall have become due and
payable, shall be repaid to the Company by the Trustee on written demand and all
liability of the Trustee shall thereupon cease with respect to such monies; and
the holder of any of the Notes shall thereafter look only to the Company for any
payment which such holder may be entitled to collect unless an applicable
abandoned property law designates another person.

     Section 13.5  Reinstatement. If (i) the Trustee or the paying agent is
                   -------------
unable to apply any money in accordance with Section 13.2 by reason of any order
or judgment of any court or governmental authority enjoining, restraining or
otherwise prohibiting such application and (ii) the holders of at least a
majority in principal amount of the then outstanding Notes so request by written
notice to the Trustee, the Company's obligations under this Indenture and the
Notes shall be revived and reinstated as though no deposit had occurred pursuant
to Section 13.1 until such time as the Trustee or the paying agent is permitted
to apply all such money in accordance with Section 13.2; provided, however, that
                                                         --------  -------
if the Company makes any payment of interest on or principal of any Note
following the reinstatement of its obligations, the Company shall be subrogated
to the rights of the holders of such Notes to receive such payment from the
money held by the Trustee or paying agent.

recourse for the payment of the principal of or premium, if any, or interest
(including Liquidated Damages, if any) on any Note, or for any claim based
thereon or otherwise in respect thereof, and no recourse under or upon any
obligation, covenant or agreement of the Company in this Indenture or in any
supplemental indenture or in any Note, or because of the creation of any
indebtedness represented thereby, shall be had against any incorporator,
stockholder, employee, agent, officer or director or subsidiary, as such, past,
present or future, of the Company or of any successor corporation, either
directly or through the Company or any successor corporation, whether by virtue
of any constitution, statute or rule of law, or by the enforcement of any
assessment or penalty or otherwise; it being expressly understood that all such
liability is hereby expressly waived and released as a condition of, and as a
consideration for, the execution of this Indenture and the issue of the Notes.

                              CONVERSION OF NOTES

     Section 15.1  Right to Convert.  Subject to and upon compliance with the
                   ----------------
provisions of this Indenture, the holder of any Note shall have the right, at
his option, at any time following the date of original issuance of the Notes and
prior to the close of business on August 15, 2006 (except that, with respect to
any Note or portion of a Note that shall be called for redemption, such right
shall terminate, except as provided in the fifth paragraph of Section 15.2 and
Section 3.4, at the close of business on the Business Day next preceding the
date fixed for redemption of such Note or portion of a Note unless the Company
shall default in payment due upon redemption thereof), to convert the principal
amount of any such Note, or any portion of such principal amount which is $1,000
or an integral multiple thereof, into that number of fully paid and non-
assessable shares of Common Stock (as such shares shall then be constituted)
obtained by dividing the principal amount of the Note or portion thereof
surrendered for conversion by the Conversion Price in effect at such time, by
surrender of the Note so to be converted in whole or in part in the manner
provided in Section 15.2. A holder of Notes is not entitled to any rights of a
holder of Common Stock until such holder has converted his Notes to Common
Stock, and only to the extent such Notes are deemed to have been converted to
Common Stock under this Article XV. A Note with respect to which a holder has
delivered a notice in accordance with Section 16.2 regarding such holder's
election to require the Company to repurchase such holder's Notes following the
occurrence of a Repurchase Event may be converted in accordance with this
Article XV only if such holder withdraws such notice by delivering a written
notice of withdrawal to the Company prior to the close of business on the last
Business Day prior to the day fixed for repurchase.

     Section 15.2  Exercise of Conversion Privilege; Issuance of Common Stock on
                   -------------------------------------------------------------
Conversion.  In order to exercise the conversion privilege with respect to any
----------
Note in definitive form, the holder of any such Note to be converted in whole or
in part shall surrender such Note, duly endorsed, at an office or agency
maintained by the Company pursuant to Section 5.2, accompanied by the funds, if
any, required by the penultimate paragraph of this Section 15.2, shall give
written notice of conversion in the form provided on the Notes (or such other
notice that is acceptable to the Company), shall provide copies of such notice
via facsimile to the Company, attention General Counsel ((650) 519-5333) and
Latham & Watkins, attention John Donohue ((650) 463-2600), and shall provide
such additional documentation or certification as the Company and/or the Trustee
may reasonably request to the office or agency specified in said notice that the
holder elects to convert such Note or such portion thereof. Such notice shall
also state the name or names (with address) in which the shares of Common Stock
which shall be issuable on such conversion shall be issued, and shall be
accompanied by transfer taxes, if required pursuant to Section 15.7. Each such
Note surrendered for conversion shall, unless the shares issuable on conversion
are to be issued in the same name as the registration of such Note, be duly
endorsed by, or be accompanied by instruments of transfer (including a broker's
letter regarding compliance with the prospectus delivery requirement, if
applicable) in form satisfactory to the Company duly executed by, the holder or
his duly authorized attorney.

                                      -54-
<PAGE>

     The Company shall use its reasonable best efforts to, within three (3)
Business Days after the Conversion Date (as defined below) with respect to any
Note, subject to compliance with any restrictions on transfer if shares issuable
on conversion are to be issued in a name other than that of the Noteholder (as
if such transfer were a transfer of the Note or Notes (or portion thereof) so
converted), issue and deliver to such holder at the office or agency maintained
by the Company for such purpose pursuant to Section 5.2, the number of full
shares of Common Stock issuable upon the conversion of such Note or portion
thereof in accordance with the provisions of this Article and a check or cash in
respect of any fractional interest in respect of a share of Common Stock arising
upon such conversion, as provided in Section 15.3 (which payment, if any, shall
be paid no later than ten (10) Business Days after the Conversion Date).  In
case any Note of a denomination greater than $1,000 shall be surrendered for
partial conversion, and subject to Section 2.3, the Company shall execute and
the Trustee shall authenticate and deliver to the holder of the Note so
surrendered, without charge to him, a new Note or Notes in authorized
denominations in an aggregate principal amount equal to the unconverted portion
of the surrendered Note.

     If the Company shall not have delivered the number of shares of Common
Stock issued upon conversion of Notes by any holder within ten (10) Business
Days after the Conversion Date with respect to such Notes, the Company shall pay
liquidated damages to such holder in the amount of one percent (1%) of the
outstanding principal amount of Notes so converted by such holder.

     The conversion shall be deemed to have been effected as to any such Note
(or portion thereof) on the date on which the requirements set forth above in
this Section 15.2 have been satisfied as to such Note (or portion thereof) (such
date, the "Conversion Date"), and the person in whose name any shares of Common
Stock shall be issuable upon such conversion shall be deemed to have become on
the Conversion Date the holder of record of the shares represented thereby;

provided, however, that any such surrender on any date when the stock transfer
--------  -------
books of the Company shall be closed shall constitute the person in whose name
the certificates are to be issued as the record holder thereof for all purposes
on the next succeeding day on which such stock transfer books are open, but such
conversion shall be at the Conversion Price in effect on the date upon which
such Note shall be surrendered.  For purposes of determining satisfaction of the
requirement set forth above with respect to the Conversion Date for any Note,
any facsimile required to be sent shall be deemed to have been sent on a given
day if such facsimile was sent before 11:00 a.m., New York City time, on such
date, to the number listed above (unless a different number is specified in a
notice filed with the Trustee and mailed by the Trustee, at the Company's
expense, to each holder of the Notes at such holder's address appearing in the
Note register, as provided for in Section 2.5 of this Indenture) and a
confirmation of transmission of such facsimile is obtained.

     The Company shall pay in cash, on any Note or portion thereof surrendered
for conversion during the period from the close of business on any interest
payment date to which interest has been fully paid through the close of business
on the Business Day preceding the record date for the next such interest payment
date, accrued and unpaid interest, if any, to, but excluding, the date of
conversion.  Any such payment of interest shall be made with respect to such
Note within ten (10) Business Days after the Conversion Date.  Notwithstanding
the foregoing, any Note or portion

                                      -55-
<PAGE>

thereof surrendered for conversion during the period from the close of business
on the record date for any interest payment date through the close of business
on the Business Day next preceding such interest payment date shall (unless such
Note or portion thereof being converted shall have been called for redemption
pursuant to a redemption notice mailed to the Noteholders in accordance with
Section 3.2 or shall have become due prior to such interest payment date as a
result of a Repurchase Event) be accompanied by payment, in New York Clearing
House funds or other funds acceptable to the Company, of an amount equal to the
interest otherwise payable on such interest payment date on the principal amount
being converted; provided, however, that no such payment need be made if there
                 --------  -------
shall exist at the time of conversion a default in the payment of interest on
the Notes. Except as provided in this Section 15.2, no adjustment shall be made
for interest accrued on any Note converted or for dividends on any shares issued
upon the conversion of such Note as provided in this Article.

     Section 15.3  Cash Payments in Lieu of Fractional Shares.  No fractional
                   ------------------------------------------
shares of Common Stock or scrip representing fractional shares shall be issued
upon conversion of Notes. If more than one Note shall be surrendered for
conversion at one time by the same holder, the number of full shares which shall
be issuable upon conversion thereof shall be computed on the basis of the
aggregate principal amount of the Notes (or specified portions thereof to the
extent permitted hereby) so surrendered for conversion. If any fractional share
of stock otherwise would be issuable upon the conversion of any Note or Notes,
the Company shall calculate and pay a cash adjustment in lieu of such fractional
share at the current market value thereof to the holder of Notes. The current
market value of a share of Common Stock shall be the Closing Price on the first
Trading Day immediately preceding the day on which the Notes (or specified
portions thereof) are deemed to have been converted and such Closing Price shall
be determined as provided in Section 15.5(h).

     Section 15.4  Conversion Price.  The conversion price shall be as
                   ----------------
specified in the form of Note (herein called the "Conversion Price") attached as
Exhibit A hereto, subject to adjustment as provided in this Article XV.
---------

     Section 15.5  Adjustment of Conversion Price.  The Conversion Price shall
                   ------------------------------
be adjusted from time to time by the Company as follows:

          (a)  In case the Company shall hereafter pay a dividend or make a
     distribution to all holders of the outstanding Common Stock in shares of
     Common Stock, the Conversion Price in effect at the opening of business on
     the date following the date fixed for the determination of stockholders
     entitled to receive such dividend or other distribution shall be reduced by
     multiplying such Conversion Price by a fraction of which the numerator
     shall be the number of shares of Common Stock outstanding at the close of
     business on the Record Date (as defined in Section 15.5(h)) fixed for such
     determination and the denominator shall be the sum of such number of shares
     and the total number of shares constituting such dividend or other
     distribution, such reduction to become effective immediately after the
     opening of business on the day following the Record Date. If any dividend
     or distribution of the type described in this Section 15.5(a) is declared
     but not so paid or made, the Conversion

                                      -56-
<PAGE>

     Price shall again be adjusted to the Conversion Price which would then be
     in effect if such dividend or distribution had not been declared.

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

          (c)  Subject to Section 15.11(b) hereof, in case the Company shall
     issue rights or warrants to all holders of its outstanding shares of Common
     Stock entitling them (for a period expiring within forty-five (45) days
     after the date fixed for the determination of stockholders entitled to
     receive such rights or warrants) to subscribe for or purchase shares of
     Common Stock at a price per share less than the Current Market Price (as
     defined in Section 15.5(h)) on the Record Date fixed for the determination
     of stockholders entitled to receive such rights or warrants, the Conversion
     Price shall be adjusted so that the same shall equal the price determined
     by multiplying the Conversion Price in effect at the opening of business on
     the date after such Record Date by a fraction of which the numerator shall
     be the sum of the number of shares of Common Stock outstanding at the close
     of business on the Record Date plus the number of shares that the aggregate
     offering price of the total number of shares so offered for subscription or
     purchase would purchase at such Current Market Price, and of which the
     denominator shall be the sum of the number of shares of Common Stock
     outstanding at the close of business on the Record Date plus the total
     number of additional shares of Common Stock so offered for subscription or
     purchase. Such adjustment shall become effective immediately after the
     opening of business on the day following the Record Date fixed for
     determination of stockholders entitled to receive such rights or warrants.
     To the extent that shares of Common Stock are not delivered pursuant to
     such rights or warrants, upon the expiration or termination of such rights
     or warrants the Conversion Price shall be readjusted to the Conversion
     Price that would then be in effect had the adjustments made upon the
     issuance of such rights or warrants been made on the basis of delivery of
     only the number of shares of Common Stock actually delivered. In the event
     that such rights or warrants are not so issued, the Conversion Price shall
     again be adjusted to be the Conversion Price that would then be in effect
     if such date fixed for the determination of stockholders entitled to
     receive such rights or warrants had not been fixed. In determining whether
     any rights or warrants entitle the holders to subscribe for or purchase
     shares of Common Stock at less than such Current Market Price, and in
     determining the aggregate offering price of such shares of Common Stock,
     there shall be taken into account any consideration received for such
     rights or warrants, the value of such consideration, if other than cash, to
     be determined by the Board of Directors.

                                      -57-

          (d)  Subject to Section 15.11(b) hereof, in case the Company shall, by
     dividend or otherwise, distribute to all holders of its Common Stock shares
     of any class of capital stock of the Company (other than any dividends or
     distributions to which Section 15.5(a) applies) or evidences of its
     indebtedness or other assets (including securities, but excluding (1) any
     rights or warrants referred to in Section 15.5(c) and (2) dividends and
     distributions paid exclusively in cash (except as set forth in Section
     15.5(e) and (f), (the foregoing hereinafter in this Section 15.5(d) called
     the "Securities")), unless the Company elects to reserve such Securities
     for distribution to the Noteholders upon conversion of the Notes so that
     any such holder converting Notes will receive upon such conversion, in
     addition to the shares of Common Stock to which such holder is entitled,
     the amount and kind of such Securities which such holder would have
     received if such holder had converted its Notes into Common Stock
     immediately prior to the Record Date (as defined in Section 15.5(h) for
     such distribution of the Securities) then, in each such case, the
     Conversion Price shall be reduced so that the same shall be equal to the
     price determined by multiplying the Conversion Price in effect immediately
     prior to the close of business on the Record Date (as defined in Section
     15.5(h)) with respect to such distribution by a fraction of which the
     numerator shall be the Current Market Price (determined as provided in
     Section 15.5(h)) on such date less the fair market value (as determined by
     the Board of Directors, whose determination shall be conclusive and
     described in a Board Resolution) on such date of the portion of the
     Securities so distributed applicable to one share of Common Stock and the
     denominator shall be such Current Market Price, such reduction to become
     effective immediately prior to the opening of business on the day following
     the Record Date; provided, however, that in the event the then fair market
                      --------  -------
     value (as so determined) of the portion of the Securities so distributed
     applicable to one share of Common Stock is equal to or greater than the
     Current Market Price on the Record Date, in lieu of the foregoing
     adjustment, adequate provision shall be made so that each Noteholder shall
     have the right to receive upon conversion of a Note (or any portion
     thereof) the amount of Securities such holder would have received had such
     holder converted such Note (or portion thereof) immediately prior to such
     Record Date.  In the event that such dividend or distribution is not so
     paid or made, the Conversion Price shall again be adjusted to be the
     Conversion Price which would then be in effect if such dividend or
     distribution had not been declared.  If the Board of Directors determines
     the fair market value of any distribution for purposes of this Section
     15.5(d) by reference to the actual or when issued trading market for any
     securities comprising all or part of such distribution, it must in doing so
     consider the prices in such market over the same period (the "Reference
     Period") used in computing the Current Market Price pursuant to Section
     15.5(h) to the extent possible, unless the Board of Directors in a board
     resolution determines that determining the fair market value during the
     Reference Period would not be in the best interest of the Noteholder.

          In the event that the Company implements a new stockholder rights
     plan, such rights plan shall provide that upon conversion of the Notes the
     holders will receive, in addition to the Common Stock issuable upon such
     conversion, the rights issued under such rights plan (notwithstanding the
     occurrence of an event causing such rights to separate from the Common
     Stock at or prior to the time of conversion).  Any distribution of rights
     or warrants

                                      -58-
<PAGE>

     pursuant to a stockholder rights plan complying with the requirements set
     forth in the immediately preceding sentence of this paragraph shall not
     constitute a distribution of rights or warrants for the purposes of this
     Section 15.5(d).

          Rights or warrants distributed by the Company to all holders of Common
     Stock entitling the holders thereof to subscribe for or purchase shares of
     the Company's capital stock (either initially or under certain
     circumstances), which rights or warrants, until the occurrence of a
     specified event or events ("Trigger Event"): (i) are deemed to be
     transferred with such shares of Common Stock; (ii) are not exercisable; and
     (iii) are also issued in respect of future issuances of Common Stock, shall
     be deemed not to have been distributed for purposes of this Section 15.5(d)
     (and no adjustment to the Conversion Price under this Section 15.5(d) will
     be required) until the occurrence of the earliest Trigger Event.  If such
     right or warrant is subject to subsequent events, upon the occurrence of
     which such right or warrant shall become exercisable to purchase different
     securities, evidences of indebtedness or other assets or entitle the holder
     to purchase a different number or amount of the foregoing or to purchase
     any of the foregoing at a different purchase price, then the occurrence of
     each such event shall be deemed to be the date of issuance and record date
     with respect to a new right or warrant (and a termination or expiration of
     the existing right or warrant without exercise by the holder thereof).  In
     addition, in the event of any distribution (or deemed distribution) of
     rights or warrants, or any Trigger Event or other event (of the type
     described in the preceding sentence) with respect thereto, that resulted in
     an adjustment to the Conversion Price under this Section 15.5(d), (1) in
     the case of any such rights or warrants that shall all have been redeemed
     or repurchased without exercise by any holders thereof, the Conversion
     Price shall be readjusted upon such final redemption or repurchase to give
     effect to such distribution or Trigger Event, as the case may be, as though
     it were a cash distribution, equal to the per share redemption or
     repurchase price received by a holder of Common Stock with respect to such
     rights or warrants (assuming such holder had retained such rights or
     warrants), made to all holders of Common Stock as of the date of such
     redemption or repurchase, and (2) in the case of such rights or warrants
     all of which shall have expired or been terminated without exercise, the
     Conversion Price shall be readjusted as if such rights and warrants had
     never been issued.

          For purposes of this Section 15.5(d) and Sections 15.5(a) and (c), any
     dividend or distribution to which this Section 15.5(d) is applicable that
     also includes shares of Common Stock, or rights or warrants to subscribe
     for or purchase shares of Common Stock to which Section 15.5(c) applies (or
     both), shall be deemed instead to be (1) a dividend or distribution of the
     evidences of indebtedness, assets, shares of capital stock, rights or
     warrants other than such shares of Common Stock or rights or warrants to
     which Section 15.5(c) applies (and any Conversion Price reduction required
     by this Section 15.5(e) with respect to such dividend or distribution shall
     then be made) immediately followed by (2) a dividend or distribution of
     such shares of Common Stock or such rights or warrants (and any further
     Conversion Price reduction required by Sections 15.5(a) and (c) with
     respect to such dividend or distribution shall then be made, except (A) the
     Record Date of such dividend or distribution shall be

                                      -59-
<PAGE>

     substituted as "the date fixed for the determination of stockholders
     entitled to receive such dividend or other distribution", "Record Date
     fixed for such determination" and "Record Date" within the meaning of
     Section 15.5(a) and as "the date fixed for the determination of
     stockholders entitled to receive such rights or warrants", "the Record Date
     fixed for the determination of the stockholders entitled to receive such
     rights or warrants" and "such Record Date" within the meaning of Section
     15.5(c) and (B) any shares of Common Stock included in such dividend or
     distribution shall not be deemed "outstanding at the close of business on
     the date fixed for such determination" within the meaning of Section
     15.5(a).

          (e)  In case the Company shall, by dividend or otherwise, distribute
     to all holders of its Common Stock cash (excluding any cash that is
     distributed upon a merger or consolidation to which Section 15.6 applies or
     as part of a distribution referred to in Section 15.5(d)), in an aggregate
     amount that, combined together with (1) the aggregate amount of any other
     such distributions to all holders of its Common Stock made exclusively in
     cash within the twelve (12) months preceding the date of payment of such
     distribution, and in respect of which no adjustment pursuant to this
     Section 15.5(e) has been made, and (2) the aggregate of any cash plus the
     fair market value (as determined by the Board of Directors, whose
     determination shall be conclusive and described in a Board Resolution) of
     consideration payable in respect of any tender offer by the Company or any
     of its subsidiaries for all or any portion of the Common Stock concluded
     within the twelve (12) months preceding the date of payment of such
     distribution, and in respect of which no adjustment pursuant to Section
     15.5(f) has been made, exceeds 10% of the product of the Current Market
     Price (determined as provided in Section 15.5(h)) on the Record Date with
     respect to such distribution times the number of shares of Common Stock
     outstanding on such date, then, and in each such case, immediately after
     the close of business on such date, the Conversion Price shall be reduced
     so that the same shall equal the price determined by multiplying the
     Conversion Price in effect immediately prior to the close of business on
     such Record Date by a fraction (i) the numerator of which shall be equal to
     the Current Market Price on the Record Date less an amount equal to the
     quotient of (x) the excess of such combined amount over such 10% and (y)
     the number of shares of Common Stock outstanding on the Record Date and
     (ii) the denominator of which shall be equal to the Current Market Price on
     such date; provided, however, that in the event the portion of the cash so
                --------  -------
     distributed applicable to one share of Common Stock is equal to or greater
     than the Current Market Price of the Common Stock on the Record Date, in
     lieu of the foregoing adjustment, adequate provision shall be made so that
     each Noteholder shall have the right to receive upon conversion of a Note
     (or any portion thereof) the amount of cash such holder would have received
     had such holder converted such Note (or portion thereof) immediately prior
     to such Record Date. In the event that such dividend or distribution is not
     so paid or made, the Conversion Price shall again be adjusted to be the
     Conversion Price that would then be in effect if such dividend or
     distribution had not been declared.

          (f)  In case a tender offer made by the Company or any Subsidiary for
     all or any portion of the Common Stock shall expire and such tender offer
     (as amended upon the

                                      -60-
<PAGE>

     expiration thereof) shall require the payment to stockholders (based on the
     acceptance (up to any maximum specified in the terms of the tender offer)
     of Purchased Shares (as defined below)) of an aggregate consideration
     having a fair market value (as determined by the Board of Directors, whose
     determination shall be conclusive and described in a Board Resolution) that
     combined together with (1) the aggregate of the cash plus the fair market
     value (as determined by the Board of Directors, whose determination shall
     be conclusive and described in a Board Resolution), as of the expiration of
     such tender offer, of consideration payable in respect of any other tender
     offers, by the Company or any of its subsidiaries for all or any portion of
     the Common Stock expiring within the twelve (12) months preceding the
     expiration of such tender offer and in respect of which no adjustment
     pursuant to this Section 15.5(f) has been made and (2) the aggregate amount
     of any distributions to all holders of the Company's Common Stock made
     exclusively in cash within twelve (12) months preceding the expiration of
     such tender offer and in respect of which no adjustment pursuant to Section
     15.5(e) has been made, exceeds 10% of the product of the Current Market
     Price (determined as provided in Section 15.5(h)) as of the last time (the
     "Expiration Time") tenders could have been made pursuant to such tender
     offer (as it may be amended) times the number of shares of Common Stock
     outstanding (including any tendered shares) on the Expiration Time, then,
     and in each such case, immediately prior to the opening of business on the
     day after the date of the Expiration Time, the Conversion Price shall be
     adjusted so that the same shall equal the price determined by multiplying
     the Conversion Price in effect immediately prior to close of business on
     the date of the Expiration Time by a fraction of which the numerator shall
     be the number of shares of Common Stock outstanding (including any tendered
     shares) on the Expiration Time multiplied by the Current Market Price of
     the Common Stock on the Trading Day next succeeding the Expiration Time and
     the denominator shall be the sum of (x) the fair market value (determined
     as aforesaid) of the aggregate consideration payable to stockholders based
     on the acceptance (up to any maximum specified in the terms of the tender
     offer) of all shares validly tendered and not withdrawn as of the
     Expiration Time (the shares deemed so accepted, up to any such maximum,
     being referred to as the "Purchased Shares") and (y) the product of the
     number of shares of Common Stock outstanding (less any Purchased Shares) on
     the Expiration Time and the Current Market Price of the Common Stock on the
     Trading Day next succeeding the Expiration Time, such reduction (if any) to
     become effective immediately prior to the opening of business on the day
     following the Expiration Time. In the event that the Company is obligated
     to purchase shares pursuant to any such tender offer, but the Company is
     permanently prevented by applicable law from effecting any such purchases
     or all such purchases are rescinded, the Conversion Price shall again be
     adjusted to be the Conversion Price that would then be in effect if such
     tender offer had not been made. If the application of this Section 15.5(f)
     to any tender offer would result in an increase in the Conversion Price, no
     adjustment shall be made for such tender offer under this Section 15.5(f).

          (g) In case of a tender or exchange offer made by a person other than
     the Company or any Subsidiary for an amount that increases the offeror's
     ownership of Common Stock to more than 25% of the Common Stock outstanding
     and shall involve the payment by

                                      -61-
<PAGE>

     such person of consideration per share of Common Stock having a fair market
     value (as determined by the Board of Directors in good faith, whose
     determination shall be conclusive, and described in a resolution of the
     Board of Directors) at the last time (the "Expiration Time") tenders or
     exchanges may be made pursuant to such tender or exchange offer (as it
     shall have been amended) that exceeds the Current Market Price of the
     Common Stock on the Trading Day next succeeding the Expiration Time, and in
     which, as of the Expiration Time the Board of Directors is not recommending
     rejection of the offer, the Conversion Price shall be reduced so that the
     same shall equal the price determined by multiplying the Conversion Price
     in effect immediately prior to the Expiration Time by a fraction of which
     the numerator shall be the number of shares of Common Stock outstanding
     (including any tendered or exchanged shares) on the Expiration Time
     multiplied by the current Market Price of the Common Stock on the Trading
     Day next succeeding the Expiration Time and the denominator shall be the
     sum of (x) the fair market value (determined as aforesaid) of the aggregate
     consideration payable to stockholders based on the acceptance (up to any
     maximum specified in the terms of the tender or exchange offer) of all
     shares validly tendered or exchanged and not withdrawn as of the Expiration
     Time (the shares deemed so accepted, up to any such maximum, being referred
     to as the "Purchased Shares") and (y) the product of the number of shares
     of Common Stock outstanding (less any Purchased Shares) on the Expiration
     Time and the Current Market Price of the Common Stock on the Trading Day
     next succeeding the Expiration Time, such reduction to become effective
     immediately prior to the opening of business on the day following the
     Expiration Time. In the event that such person is obligated to purchase
     shares pursuant to any such tender or exchange offer, but such person is
     permanently prevented by applicable law from effecting any such purchases
     or all such purchases are rescinded, the Conversion Price shall again be
     adjusted to be the Conversion Price that would then be in effect if such
     tender or exchange offer had not been made. Notwithstanding the foregoing,
     the adjustment described in this Section 15.5(g) shall not be made if, as
     of the Expiration Time, the offering documents with respect to such offer
     disclose a plan or intention to cause the Company to engage in any
     transaction described in Article XII.

          (h)  For purposes of this Section 15.5 and Section 15.11, the
     following terms shall have the meaning indicated:

               (1)  "Closing Price" with respect to any securities on any day
          shall mean the closing sale price regular way on such day or, in case
          no such sale takes place on such day, the average of the reported
          closing bid and asked prices, regular way, in each case on the Nasdaq
          National Market or New York Stock Exchange, as applicable, or, if such
          security is not listed or admitted to trading on such National Market
          or Exchange, on the principal national security exchange or quotation
          system on which such security is quoted or listed or admitted to
          trading, or, if not quoted or listed or admitted to trading on any
          national securities exchange or quotation system, the average of the
          closing bid and asked prices of such security on the over-the-counter
          market on the day in question as reported by the National Quotation
          Bureau

                                      -62-
<PAGE>

          Incorporated, or a similar generally accepted reporting service, or if
          not so available, in such manner as furnished by any New York Stock
          Exchange member firm selected from time to time by the Board of
          Directors for that purpose, or a price determined in good faith by the
          Board of Directors, whose determination shall be conclusive and
          described in a Board Resolution.

               (2)  "Current Market Price" shall mean the average of the daily
          Closing Prices per share of Common Stock for the ten (10) consecutive
          Trading Days immediately prior to the date in question; provided,
                                                                  --------
          however, that (1) if the "ex" date (as hereinafter defined) for any
          -------
          event (other than the issuance or distribution requiring such
          computation) that requires an adjustment to the Conversion Price
          pursuant to Section 15.5(a), (b), (c), (d), (e), (f) or (g) occurs
          during such ten (10) consecutive Trading Days, the Closing Price for
          each Trading Day prior to the "ex" date for such other event shall be
          adjusted by multiplying such Closing Price by the same fraction by
          which the Conversion Price is so required to be adjusted as a result
          of such other event, (2) if the "ex" date for any event (other than
          the issuance or distribution requiring such computation) that requires
          an adjustment to the Conversion Price pursuant to Section 15.5(a),
          (b), (c), (d), (e), (f) or (g) occurs on or after the "ex" date for
          the issuance or distribution requiring such computation and prior to
          the day in question, the Closing Price for each Trading Day on and
          after the "ex" date for such other event shall be adjusted by
          multiplying such Closing Price by the reciprocal of the fraction by
          which the Conversion Price is so required to be adjusted as a result
          of such other event, and (3) if the "ex" date for the issuance or
          distribution requiring such computation is prior to the day in
          question, after taking into account any adjustment required pursuant
          to clause (1) or (2) of this proviso, the Closing Price for each
          Trading Day on or after such "ex" date shall be adjusted by adding
          thereto the amount of any cash and the fair market value (as
          determined by the Board of Directors in a manner consistent with any
          determination of such value for purposes of Section 15.5(d), (f) or
          (g), whose determination shall be conclusive and described in a Board
          Resolution) of the evidences of indebtedness, shares of capital stock
          or assets being distributed applicable to one share of Common Stock as
          of the close of business on the day before such "ex" date. For
          purposes of any computation under Sections 15.5(f) or (g), the Current
          Market Price of the Common Stock on any date shall be deemed to be the
          average of the daily Closing Prices per share of Common Stock for such
          day and the next two succeeding Trading Days; provided, however,
                                                        --------  -------
          that if the "ex" date for any event (other than the tender offer
          requiring such computation) that requires an adjustment to the
          Conversion Price pursuant to Section 15.5(a), (b), (c), (d), (e), (f)
          and (g) occurs on or after the Expiration Time for the tender or
          exchange offer requiring such computation and prior to the day in
          question, the Closing Price for each Trading Day on and after the "ex"
          date for such other event shall be adjusted by multiplying such
          Closing Price by the reciprocal of the fraction by which the
          Conversion Price is so required to be adjusted as a result of such
          other event. For purposes of this paragraph, the term "ex" date, (1)
          when used

                                      -63-
<PAGE>

          with respect to any issuance or distribution, means the first date on
          which the Common Stock trades regular way on the relevant exchange or
          in the relevant market from which the Closing Price was obtained
          without the right to receive such issuance or distribution, (2) when
          used with respect to any subdivision or combination of shares of
          Common Stock, means the first date on which the Common Stock trades
          regular way on such exchange or in such market after the time at which
          such subdivision or combination becomes effective, and (3) when used
          with respect to any tender or exchange offer means the first date on
          which the Common Stock trades regular way on such exchange or in such
          market after the Expiration Time of such offer. Notwithstanding the
          foregoing, whenever successive adjustments to the Conversion Price are
          called for pursuant to this Section 15.5, such adjustments shall be
          made to the Current Market Price as may be necessary or appropriate to
          effectuate the intent of this Section 15.5 and to avoid unjust or
          inequitable results as determined in good faith by the Board of
          Directors.

               (3)  "fair market value" shall mean the amount which a willing
          buyer would pay a willing seller in an arm's length transaction.

               (4)  "Record Date" shall mean, with respect to any dividend,
          distribution or other transaction or event in which the holders of
          Common Stock have the right to receive any cash, securities or other
          property or in which the Common Stock (or other applicable security)
          is exchanged for or converted into any combination of cash, securities
          or other property, the date fixed for determination of stockholders
          entitled to receive such cash, securities or other property (whether
          such date is fixed by the Board of Directors or by statute, contract
          or otherwise).

               (5)  "Trading Day" shall mean (x) if the applicable security is
          listed or admitted for trading on the New York Stock Exchange or
          another national security exchange, a day on which the New York Stock
          Exchange or such other national security exchange, as applicable, is
          open for business or (y) if the applicable security is quoted on the
          Nasdaq National Market, a day on which trades may be made thereon or
          (z) if the applicable security is not so listed, admitted for trading
          or quoted, any day other than a Saturday or Sunday or a day on which
          banking institutions in the State of New York are authorized or
          obligated by law or executive order to close.

          (i)  The Company may make such reductions in the Conversion Price, in
     addition to those required by Sections 15.5(a), (b), (c), (d), (e), (f) and
     (g) and Section 15.11, as the Board of Directors considers to be advisable
     to avoid or diminish any income tax to holders of Common Stock or rights to
     purchase Common Stock resulting from any dividend or distribution of stock
     (or rights to acquire stock) or from any event treated as such for income
     tax purposes.

          To the extent permitted by applicable law, the Company from time to
     time may reduce the Conversion Price by any amount for any period of time
     if the period is at least

                                      -64-
<PAGE>

     twenty (20) days, the reduction is irrevocable during the period and the
     Board of Directors shall have made a determination that such reduction
     would be in the best interests of the Company, which determination shall be
     conclusive and described in a Board Resolution. Whenever the Conversion
     Price is reduced pursuant to the preceding sentence, the Company shall mail
     to the holder of each Note at his last address appearing on the Note
     register provided for in Section 2.5 a notice of the reduction at least
     fifteen (15) days prior to the date the reduced Conversion Price takes
     effect, and such notice shall state the reduced Conversion Price and the
     period during which it will be in effect.

          (j)  No adjustment in the Conversion Price shall be required under
     this Section 15.5 unless such adjustment would require an increase or
     decrease of at least 1% in such price; provided, however, that any
                                            --------  -------
     adjustments which by reason of this Section 15.5(j) are not required to be
     made shall be carried forward and taken into account in any subsequent
     adjustment. All calculations under this Article XV shall be made by the
     Company and shall be made to the nearest cent or to the nearest one
     hundredth of a share, as the case may be. No adjustment need be made for a
     change in the par value or no par value of the Common Stock.

          (k)  Whenever the Conversion Price is adjusted as provided in this
     Section 15.5, the Company shall promptly file with the Trustee and any
     conversion agent other than the Trustee an Officer's Certificate setting
     forth the Conversion Price after such adjustment and setting forth a brief
     statement of the facts requiring such adjustment. Promptly after delivery
     of such certificate, the Company shall prepare a notice of such adjustment
     of the Conversion Price setting forth the adjusted Conversion Price and the
     date on which each adjustment becomes effective and shall mail such notice
     of such adjustment of the Conversion Price to the holder of each Note at
     his last address appearing on the Note register provided for in Section
     2.5, within twenty (20) days of the effective date of such adjustment.
     Failure to deliver such notice shall not effect the legality or validity of
     any such adjustment.

          (l)  In any case in which this Section 15.5 provides that an
     adjustment shall become effective immediately after a Record Date for an
     event, the Company may defer until the occurrence of such event (i) issuing
     to the holder of any Note converted after such Record Date and before the
     occurrence of such event the additional shares of Common Stock issuable
     upon such conversion by reason of the adjustment required by such event
     over and above the Common Stock issuable upon such conversion before giving
     effect to such adjustment and (ii) paying to such holder any amount in cash
     in lieu of any fraction pursuant to Section 15.3.

          (m)  For purposes of this Section 15.5, the number of shares of Common
     Stock at any time outstanding shall not include shares held in the treasury
     of the Company but shall include shares issuable in respect of scrip
     certificates issued in lieu of fractions of shares of Common Stock. The
     Company will not pay any dividend or make any distribution on shares of
     Common Stock held in the treasury of the Company.

     Section 15.6  Effect of Reclassification, Consolidation, Merger or Sale.
                   ---------------------------------------------------------
If any of the following events occur, namely (i) any reclassification or change
of the outstanding shares of Common Stock (other than a change in par value, or
from par value to no par value, or from no par value to par value, or as a
result of a subdivision or combination), (ii) any consolidation, merger or
combination of the Company with another person as a result of which holders of
Common Stock shall be entitled to receive stock, securities or other property or
assets (including cash) with respect to or in exchange for such Common Stock,
(iii) any statutory exchange as a result of which holders of Common Stock
generally shall be entitled to receive stock, securities or other property or
assets (including cash) with respect to or in exchange for such Common Stock
(such transaction, a "Statutory Exchange"), or (iv) any sale or conveyance of
the properties and assets of the Company as, or substantially as, an entirety to
any other person as a result of which holders of Common Stock shall be entitled
to receive stock, securities or other property or assets (including cash) with
respect to or in exchange for such Common Stock, then the Company or the
successor or purchasing person, as the case may be, shall execute with the
Trustee a supplemental indenture (which shall comply with the Trust Indenture
Act as in force at the date of execution of such supplemental indenture if such
supplemental indenture is then required to so comply) providing that such Note
shall be convertible into the kind and amount of shares of stock and other
securities or property or assets (including cash) receivable upon such
reclassification, change, consolidation, merger, combination, Statutory
Exchange, sale or conveyance by a holder of a number of shares of Common Stock
issuable upon conversion of such Notes (assuming, for such purposes, a
sufficient number of authorized shares of Common Stock available to convert all
such Notes) immediately prior to such reclassification, change, consolidation,
merger, combination, Statutory Exchange, sale or conveyance assuming such holder
of Common Stock did not exercise his rights of election, if any, that holders of
Common Stock who were entitled to vote or consent to such transaction had as to
the kind or amount of securities, cash or other property receivable upon such
consolidation, merger, combination, Statutory Exchange, sale or conveyance
(provided that, if the kind or amount of securities, cash or other property
receivable upon such consolidation, merger, combination, Statutory Exchange,
sale or conveyance is not the same for each share of Common Stock in respect of
which such rights of election shall not have been exercised ("non-electing
share"), then for the purposes of this Section 15.6 the kind and amount of
securities, cash or other property receivable upon such consolidation, merger,
combination, Statutory Exchange, sale or conveyance for each non-electing share
shall be deemed to be the kind and amount so receivable per share by a plurality
of the non-electing shares). Such supplemental indenture shall provide for
adjustments which shall be as nearly equivalent as may be practicable to the
adjustments provided for in this Article. If, in the case of any such
reclassification, change, consolidation, merger, combination, Statutory
Exchange, sale or conveyance, the stock or other securities and assets
receivable thereupon by a holder of shares of Common Stock include shares of
stock or other securities and assets of a person other than the successor or
purchasing person, as the case may be, in such reclassification, change,
consolidation, merger, combination, Statutory Exchange, sale or conveyance, then
such supplemental indenture shall also be executed by such other person and
shall contain such additional provisions to protect the interests of the holders
of the Notes as the Board of Directors shall reasonably consider necessary by
reason of the foregoing, including to the extent practicable the provisions
providing for the repurchase rights set forth in Article XVI herein.

                                      -66-
<PAGE>

     The Company shall cause notice of the execution of such supplemental
indenture to be mailed to each holder of Notes, at his address appearing on the
Note register provided for in Section 2.5 of this Indenture, within twenty (20)
days after execution thereof.  Failure to deliver such notice shall not affect
the legality or validity of such supplemental indenture.

     The above provisions of this Section shall similarly apply to successive
reclassifications, changes, consolidations, mergers, combinations, sales and
conveyances.

     If this Section 15.6 applies to any event or occurrence, Section 15.5 shall
not apply.

     Section 15.7  Taxes on Shares Issued.  The issue of stock certificates on
                   ----------------------
conversions of Notes shall be made without charge to the converting Noteholder
for any tax in respect of the issue thereof. The Company shall not, however, be
required to pay any tax which may be payable in respect of any transfer involved
in the issue and delivery of stock in any name other than that of the holder of
any Note converted, and the Company shall not be required to issue or deliver
any such stock certificate unless and until the person or persons requesting the
issue thereof shall have paid to the Company the amount of such tax or shall
have established to the satisfaction of the Company that such tax has been paid.

     Section 15.8  Reservation of Shares; Shares to be Fully Paid; Listing of
                   ----------------------------------------------------------
Common Stock.  The Company shall provide, free from preemptive rights, out of
------------
its authorized but unissued shares or shares held in treasury, sufficient shares
to provide for the conversion of the Notes from time to time as such Notes are
presented for conversion.

     Before taking any action which would cause an adjustment reducing the
Conversion Price below the then par value, if any, of the shares of Common Stock
issuable upon conversion of the Notes, the Company will take all corporate
action which may, in the opinion of its counsel, be necessary in order that the
Company may validly and legally issue shares of such Common Stock at such
adjusted Conversion Price.

     The Company covenants that all shares of Common Stock issued upon
conversion of Notes will be fully paid and non-assessable by the Company and
free from all taxes, liens and charges with respect to the issue thereof.

     The Company further covenants that if at any time the Common Stock shall be
listed on the New York Stock Exchange, Nasdaq National Market or any other
national securities exchange or automated quotation system the Company will, if
permitted by the rules of such exchange or automated quotation system, list and
keep listed, so long as the Common Stock shall be so listed on such exchange or
automated quotation system, all Common Stock issuable upon conversion of the
Notes.

     Section 15.9  Responsibility of Trustee.  The Trustee and any other
                   -------------------------
conversion agent shall not at any time be under any duty or responsibility to
any holder of Notes to determine whether any facts exist which may require any
adjustment of the Conversion Price, or with respect to the nature or

                                      -67-
<PAGE>

extent or calculation of any such adjustment when made, or with respect to the
method employed, or herein or in any supplemental indenture provided to be
employed, in making the same. The Trustee and any other conversion agent shall
not be accountable with respect to the validity or value (or the kind or amount)
of any shares of Common Stock, or of any securities or property, which may at
any time be issued or delivered upon the conversion of any Note; and the Trustee
and any other conversion agent make no representations with respect thereto.
Subject to the provisions of Section 8.1, neither the Trustee nor any conversion
agent shall be responsible for any failure of the Company to issue, transfer or
deliver any shares of Common Stock or stock certificates or other securities or
property or cash upon the surrender of any Note for the purpose of conversion or
to comply with any of the duties, responsibilities or covenants of the Company
contained in this Article. Without limiting the generality of the foregoing,
neither the Trustee nor any conversion agent shall be under any responsibility
to determine whether a supplemental indenture need be entered into under Section
15.6 or the correctness of any provisions contained in any supplemental
indenture entered into pursuant to such section relating either to the kind or
amount of shares of stock or securities or property (including cash) receivable
by Noteholders upon the conversion of their Notes after any event referred to in
such Section 15.6 or to any adjustment to be made with respect thereto, but,
subject to the provisions of Section 8.1, may accept as conclusive evidence of
the correctness of any such provisions, and shall be protected in relying upon,
the Officer's Certificate (which the Company shall be obligated to file with the
Trustee prior to the execution of any such supplemental indenture) with respect
thereto.

     Section 15.10  Notice to Holders Prior to Certain Actions.  In case:
                    ------------------------------------------

          (a)  the Company shall declare a dividend (or any other distribution)
     on its Common Stock (that would require an adjustment in the Conversion
     Price pursuant to Section 15.5); or

          (b)  the Company shall authorize the granting to the holders of its
     Common Stock of rights or warrants to subscribe for or purchase any share
     of any class or any other rights or warrants; or

          (c)  of any reclassification of the Common Stock of the Company (other
     than a subdivision or combination of its outstanding Common Stock, or a
     change in par value, or from par value to no par value, or from no par
     value to par value), or of any consolidation or merger to which the Company
     is a party and for which approval of any shareholders of the Company is
     required, or of the sale or transfer of all or substantially all of the
     assets of the Company; or

          (d)  of the voluntary or involuntary dissolution, liquidation or
     winding-up of the Company;

the Company shall cause to be filed with the Trustee and to be mailed to each
holder of Notes at his address appearing on the Note register, provided for in
Section 2.5 of this Indenture, as promptly as possible but in any event at least
fifteen days prior to the applicable date hereinafter specified, a

                                      -68-
<PAGE>

notice stating (x) the date on which a record is to be taken for the purpose of
such dividend, distribution or 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, distribution or rights are to be determined, or (y) the date
on which such reclassification, consolidation, merger, sale, transfer,
dissolution, liquidation or winding-up is expected to become effective or occur,
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 or other
property deliverable upon such reclassification, consolidation, merger, sale,
transfer, dissolution, liquidation or winding-up. Failure to give such notice,
or any defect therein, shall not affect the legality or validity of such
dividend, distribution, reclassification, consolidation, merger, sale, transfer,
dissolution, liquidation or winding-up.

     Section 15.11  Additional Conversion Price Adjustments
                    ---------------------------------------

          (a)  In addition to any adjustments to the Conversion Price required
     to be made pursuant to Section 15.5, the Conversion Price (1) shall be
     adjusted on the date which is the earlier of (A) the date by which the
     Company is required to have had the Shelf Registration Statement declared
     effective by the Securities and Exchange Commission or be subject to
     Liquidated Damages under the Registration Rights Agreement or (B) two
     calendar days after the date on which the Commission declares effective the
     Shelf Registration Statement (the earlier of such date, the "Registration
     Date"), if the Current Market Price on the Registration Date is less than
     the Conversion Price otherwise in effect on the Registration Date, to the
     greater of such Current Market Price or 75% of the Benchmark Price (as
     defined below) and (2) shall be adjusted on August 23, 2002 (the "August
     23, 2002 Date" and, together with the Registration Date, the "Adjustment
     Date"), if the Current Market Price on the August 23, 2002 Date is less
     than the Conversion Price otherwise in effect on the August 23, 2002 Date,
     to the greater of such Current Market Price or 75% of the Benchmark Price;
     provided, however, that in no event shall the Conversion Price be increased
     by any such adjustment. For purposes of this Section 15.11, the "Benchmark
     Price" shall mean $5.61, which price shall be subject to adjustment as
     provided in the following sentence. If, prior to the applicable Adjustment
     Date, any event occurs that would require an adjustment to the Conversion
     Price pursuant to Section 15.5 or Section 15.6 (without taking into account
     the effect of Section 15.5(i)), then, for each such event, the Benchmark
     Price shall be adjusted in substantially the same manner in accordance with
     the Conversion Price adjustment provisions set forth in Section 15.5 as
     determined in good faith by the Board of Directors and set forth in an
     Officer's Certificate in accordance with Section 15.11(c) hereof. The
     phrase "date in question" in Section 15.5(h)(2) used in determining the
     Current Market Price for this Section 15.11 shall be the applicable
     Adjustment Date, and the occurrence of any event of the type set forth in
     Section 15.5(h)(2) that would require an adjustment in the Closing Price
     for any Trading Day in such period of ten (10) consecutive Trading Days
     prior to the applicable Adjustment Date pursuant to Section 15.5(h)(2) will
     also result in an appropriate adjustment to the Current Market Price for
     the purposes of this 15.11 in substantially the same manner as Section
     15.5(h)(2) requires with regard to an event for which such Section
     15.5(h)(2) designates an "ex" date, all as reasonably determined in good
     faith by the Board of Directors.

                                      -69-
<PAGE>

          (b)  In addition to any adjustments to the Conversion Price required
     to be made pursuant to Section 15.5, Section 15.6 or Section 15.11(a):

               (i)  If, at any time prior to August 28, 2003, the Company
          issues, in a single transaction, Additional Stock (as defined below)
          consisting of (x) a Primary Security (as defined below) plus (y)
          warrants to purchase Common Stock (such warrants, together with the
          Primary Security, the "Combined Securities"), with an Effective
          Primary Security Issuance Price (as defined below) that is less than
          the Effective Conversion Price (as defined below) otherwise in effect
          immediately prior to such issuance, the Conversion Price shall
          thereupon be adjusted so that the Effective Conversion Price equals
          the Effective Primary Security Issuance Price.

               (ii)  If, at any time prior to August 28, 2003, the Company
          issues Additional Stock with a New Issuance Price (as defined below)
          that is less than the Effective Conversion Price otherwise in effect
          immediately prior to such issuance, the Conversion Price shall
          thereupon be adjusted so that the Effective Conversion Price equals
          the New Issuance Price; provided, however, that in the event that any
                                  --------  -------
          Common Stock Equivalent constituting such newly issued Additional
          Stock contains an adjustment provision pursuant to which the New
          Issuance Price may itself be adjusted in certain circumstances and
          such adjustment occurs, resulting in a reduction in the New Issuance
          Price (such reduced price, the "Adjusted New Issuance Price") to a
          price lower than the Conversion Price, regardless of whether such
          adjustment occurs after August 28, 2003, the Conversion Price shall
          thereupon be adjusted so that the Effective Conversion Price equals
          the Adjusted New Issuance Price;

     provided, however, that in no event shall the Conversion Price be increased
     by any such adjustment.

          In the event that an issuance by the Company of Additional Stock would
     be covered by this Section 15.11(b) as well as either Section 15.5(a) or
     Section 15.5(b), no adjustment pursuant to this Section 15.11(b) shall be
     made, and the only adjustment to the Conversion Price for such issuance of
     Additional Stock shall be made pursuant to Section 15.5(a) or Section
     15.5(b), as applicable.  In the event that an issuance by the Company of
     Additional Stock would be covered by this Section 15.11(b) as well as
     either Section 15.5(c) or Section 15.5(d), no adjustment pursuant to
     Section 15.5(c) or Section 15.5(d) shall be made, and the only adjustment
     to the Conversion Price for such issuance of Additional Stock shall be made
     pursuant to this Section 15.11(b).

          The term "Primary Security" shall mean the security (whether in the
     form of Common Stock or a Common Stock Equivalent) to which the largest
     percentage of the purchase price for the Combined Securities is allocated
     for income tax purposes by the Company.

          The term "Effective Conversion Price" shall mean the product of the
     Conversion Price otherwise in effect (not including the effect of any
     adjustments made pursuant to

                                      -70-
<PAGE>

     Section 15.11(a)) and the percentage of the aggregate purchase price for
     the securities purchased under that certain Note, Unit and Warrant Purchase
     Agreement, dated as of August 23, 2001, allocated to the Notes. The initial
     Effective Conversion Price hereunder shall be $5.45.

          The term "New Issuance Price" shall mean the per share price, the
     conversion price or the exercise price, as applicable, of the Additional
     Stock.

          The term "Effective Primary Security Issuance Price" shall mean the
     product of (i) the per share price, conversion price or exercise price, as
     applicable, of the Primary Security and (ii) the percentage of the purchase
     price for the Combined Securities allocated to the Primary Security for
     income tax purposes by the Company.

          The term "Additional Stock" shall mean any shares of Common Stock or
     Common Stock Equivalents issued by the Company other than:

               (A)  shares of Common Stock or Common Stock Equivalents issued in
                    a transaction covered by the Conversion Price adjustments
                    described in Section 15.5;

               (B)  shares of Common Stock or Common Stock Equivalents issued
                    for noncash consideration in connection with any arm's
                    length commercial agreement approved by the Board of
                    Directors, so long as the market value of all such shares of
                    Common Stock, together, with respect to Common Stock
                    Equivalents, with the market value of all shares of Common
                    Stock into or for which such Common Stock Equivalents are
                    convertible, exchangeable or exercisable, which market value
                    for each such issuance shall be measured at the time of such
                    issuance, does not exceed a cumulative aggregate of
                    $20,000,000, as determined by the Board of Directors in
                    reasonable good faith;

               (C)  shares of Common Stock and Common Stock Equivalents issued
                    for cash consideration in connection with any arm's length
                    commercial agreement approved by the Board of Directors, so
                    long as the cumulative aggregate market value of all such
                    shares of Common Stock (or with respect to Common Stock
                    Equivalents, the cumulative aggregate market value of all
                    shares of Common Stock into or for which such Common Stock
                    Equivalents are convertible, exchangeable or exercisable),
                    at the time of each such issuance, does not exceed
                    $10,000,000;

               (D)  shares of Common Stock or Common Stock Equivalents issued or
                    issuable to the Company's employees, consultants or
                    directors directly

                    or pursuant to a stock option plan or restricted stock plan
                    approved by the Board of Directors;

               (E)  warrants with an exercise price that is equal to or greater
                    than the Current Market Price on the date of issuance,
                    issued to financial institutions or lessors in connection
                    with commercial credit arrangements or equipment financings;

               (F)  shares of Common Stock or Common Stock Equivalents issuable
                    upon exercise of Common Stock Equivalents outstanding as of
                    the date hereof;

               (G)  shares of Common Stock or Common Stock Equivalents issued in
                    connection with bona fide acquisitions, mergers or similar
                    transactions, the terms of which are approved by the Board
                    of Directors; and

               (H)  shares of Common Stock issued or issuable upon conversion of
                    the Notes or exercise of the warrants issued pursuant to
                    those certain warrant agreements, dated as of the date
                    hereof, by and between the Company and The Bank of New York,
                    as warrant agent.

          (c)  Whenever the Conversion Price or Benchmark Price is adjusted as
     provided in this Section 15.11, the Company shall promptly file with the
     Trustee and any conversion agent other than the Trustee an Officer's
     Certificate setting forth the Conversion Price or Benchmark Price, as the
     case may be, after such adjustment and setting forth a brief statement of
     the facts requiring such adjustment. Promptly after delivery of such
     certificate, the Company shall prepare a notice of such adjustment of the
     Conversion Price or Benchmark Price setting forth the adjusted Conversion
     Price or Benchmark Price, as the case may be, and the date on which such
     adjustment became effective and shall mail such notice of such adjustment
     of the Conversion Price or Benchmark Price, as the case may be, to the
     holder of each Note at his last address appearing on the Note register
     provided for in Section 2.5, within twenty (20) days of the effective date
     of such adjustment. Failure to deliver such notice shall not affect the
     legality or validity of any such adjustment.

there shall occur a Repurchase Event, then each Noteholder shall have the right,
at such holder's option, to require the Company to repurchase all of such

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

          (a)  Unless the Company shall have theretofore called for redemption

     sufficient to redeem such Notes on the redemption date as set forth in
     Section 3.2, on or before the tenth (10th) calendar day after the

     the Company, the Trustee, shall mail to all holders of record of the Notes
     a notice (the "Company Notice") in the form as prepared by the Company of
     the occurrence of the Repurchase Event and of the repurchase right set
     forth herein arising as a result thereof. The Company shall also deliver a
     copy of such notice of a repurchase right to the Trustee and cause a copy

               (3)  the last date by which the election to require repurchase,
          if submitted, must be revoked;

               (4)  the Repurchase Price;

               (5)  a description of the procedure which a holder must follow
          to exercise a repurchase right; and

               (6)  the Conversion Price then in effect, the date on which the
          right to convert the principal amount of the Notes to be repurchased
          will terminate and the place or places where Notes may be surrendered
          for conversion.

                                      -73-

          No failure of the Company to give the foregoing notices or defect
     therein shall limit any holder's right to exercise a repurchase right or
     affect the validity of the proceedings for the repurchase of Notes.

          If any of the foregoing provisions are inconsistent with applicable
     law, such law shall govern.

          (b) To exercise a repurchase right, a holder shall deliver to the
     Trustee on or before the close of business on the thirty-fifth (35th) day
     after the Company Notice was mailed (i) written notice to the Company (or

     of such right, which notice shall set forth the name of the holder, the
     principal amount of the Notes to be repurchased, a statement that an
     election to exercise the repurchase right is being made thereby, and (ii)
     the Notes with respect to which the repurchase right is being exercised,
     duly endorsed for transfer to the Company. Election of repurchase by a
     holder shall be revocable at any time prior to, but excluding, the
     repurchase date, by delivering written notice to that effect to the Trustee
     prior to the close of business on the Business Day prior to the repurchase
     date.

          (c) If the Company fails to repurchase on the repurchase date any
     Notes (or portions thereof) as to which the repurchase right has been
     properly exercised, then the principal of such Notes shall, until paid,
     bear interest to the extent permitted by applicable law from the repurchase
     date at the rate borne by the Note and each such Note shall be convertible
     into Common Stock in accordance with this Indenture (without giving effect
     to Section 16.2(b)) until the principal of such Note shall have been paid
     or duly provided for.

          (d) Any Note that is to be repurchased only in part shall be
     surrendered to the Trustee duly endorsed for transfer to the Company and
     accompanied by appropriate evidence of genuineness and authority
     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 Note without service charge, a new Note or Notes, containing identical
     terms and conditions, of any authorized denomination as requested by such
     holder in aggregate principal amount equal to and in exchange for the
     unrepurchased portion of the principal of the Note so surrendered.

          (e) On or prior to the repurchase 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 5.4) the
     Repurchase Price in cash for payment to the holder on the repurchase date;
     provided that if payment is to be made in cash and such cash payment is to
     --------
     be made on the repurchase date, it must be received by the Trustee or
     paying agent, as the case may be, by 10:00 a.m., New York City time, on
     such date.

          (f) If the Company is unable to repurchase on the repurchase date all
     of the Notes (or portions thereof) as to which the repurchase right has
     been properly exercised, the aggregate amount of Notes the Company may
     repurchase shall be allocated pro rata among

                                      -74-
<PAGE>

     each Note (or portion thereof) surrendered for repurchase, based on the
     principal amount of such Note, in proportion to the aggregate amount of
     Notes surrendered for repurchase.

          (g) [Reserved.]

          (h) [Reserved.]

          (i) All Notes delivered for repurchase shall be delivered to the
     Trustee to be canceled in accordance with the provisions of Section 2.8.

     pursuant to the Exchange Act;

          (b) the term "person" or "group" shall include any syndicate or group

          (c) the term "Continuing Director" means at any date a member of the

     for such nominations or elections has been delegated to a nominating
     committee whose authority and composition have been approved by at least a
     majority of the directors who were continuing directors at the time such
     committee was formed. (Under this definition, if the Board of Directors of
     the Company as of the date of this Indenture were to approve a new director

     of the Company (the "Voting Stock"); (ii) approval by the stockholders of
     the

                                      -75-

     Company of any plan or proposal for the liquidation, dissolution or
     winding up of the Company; (iii) the Company (A) consolidates with or
     merges into any other corporation or any other corporation merges into the
     Company, and in the case of any such transaction, the outstanding Common
     Stock of the Company is changed or exchanged into other assets or
     securities as a result, unless the stockholders of the Company immediately
     before such transaction own, directly or indirectly immediately following
     such transaction, at least 51% of the combined voting power of the
     outstanding voting securities of the corporation resulting from such
     transaction in substantially the same proportion as their ownership of the
     Voting Stock immediately before such transaction, or (B) conveys, transfers
     or leases all or substantially all of its assets to any person; or (iv) any
     time Continuing Directors do not constitute a majority of the Board of

     (10) Trading Days immediately preceding the Change in Control is at least
     equal to 105% of the Conversion Price in effect on the date on which the
     Change in Control occurs and, if such Change in Control occurs on a date
     which is prior to the last date on which the Shelf Registration Statement
     is required to remain effective pursuant to the Registration Rights
     Agreement, the Shelf Registration Statement is effective and available for
     use or (y) in the case of a merger or consolidation or conveyance, transfer
     or lease otherwise constituting a Change in Control, all of the
     consideration (excluding cash payments for fractional shares) in such
     merger or consolidation constituting the Change in Control consists of
     common stock listed for trading on a United States national securities
     exchange or approved for trading on the Nasdaq National Market or the
     Nasdaq SmallCap (or which will be so traded or approved for trading when
     issued or exchanged in connection with such Change in Control) and as a
     result of such transaction or transactions such Notes become convertible
     solely into such common stock; provided, however, that the exception
                                    --------  -------
     contained in the preceding clause (y) shall only apply in the event that
     (aa) the issuer of such common stock has a total market capitalization of
     at least $150 million and (bb) the product of (i) the average daily trading
     volume of such common stock for the ten (10) Trading Days immediately
     preceding the date on which the Company either executes the definitive
     agreement with respect to the transaction otherwise constituting a Change
     in Control or, if no such definitive agreement is executed, the date on
     which the transaction otherwise constituting a Change in Control is deemed
     to have occurred, as determined by the Company in good faith (either of
     such dates, as applicable, the "Measurement Date") and (ii) the average of
     the daily volume-weighted average per share price of such common stock for
     the ten (10) Trading Days immediately preceding the Measurement Date
     exceeds $1.5 million.

          (f) the term "market capitalization" in the proviso following clause
     (y) of the preceding subsection 16.4(e) shall mean, with respect to such
     issuer, the number of shares of common stock outstanding as of the
     Measurement Date (which number shall include shares of common stock held by
     affiliates of such issuer) multiplied by the closing price per share for
     such common stock of such issuer on the Measurement Date.

                                      -76-

          (g) the term "volume-weighted average per share price" shall mean the
     volume-weighted average price of a share of common stock of an issuer
     described in the proviso following clause (y) of the preceding subsection
     16.4(e) on a given Trading Day as calculated by the AQR function by
     Bloomberg.

          (h) a "Termination of Trading" shall have occurred if the Common Stock
     (or other common stock into which the Notes are then convertible) is
     neither listed for trading on a United States national securities exchange
     nor approved for trading on the Nasdaq National Market or the Nasdaq
     SmallCap Market.

                                   TIVO INC.

                      7% Convertible Senior Note Due 2006

     This Note is one of a duly authorized issue of Notes of the Company,
designated as its 7% Convertible Senior Notes due 2006 (herein called the
"Notes"), limited to the aggregate principal amount of $__________ all issued or
to be issued under and pursuant to an Indenture dated as of August 28, 2001
(herein called the "Indenture"), between the Company and The Bank of New York,
(herein called the "Trustee"), to which the Indenture and all indentures
supplemental thereto reference is hereby made for a description of the rights,
limitations of rights, obligations, duties and immunities thereunder of the
Trustee, the Company and the holders of the Notes.  All capitalized terms used
herein without definition shall have the meaning set forth in the Indenture.

     In case an Event of Default, as defined in the Indenture, shall have
occurred and be continuing, the principal of, premium, if any, and accrued
interest on all Notes may be declared, and upon said declaration shall become,
due and payable, in the manner, with the effect and subject to the conditions
provided in the Indenture.  Liquidated damages paid pursuant to Section 15.2 of
the Indenture, if any, shall be paid within ten (10) Business Days of the date
from which such liquidated damages accrued pursuant to Section 15.2.  Liquidated
Damages on the Notes paid pursuant to Section 3(e) of the Registration Rights
Agreement, if any, shall be paid at the times and in the manner provided
therein.

     The Indenture contains provisions permitting the Company and the Trustee in
certain limited circumstances, without the consent of the holders of the Notes,
and in other circumstances, with the consent of the holders of not less than a
majority in aggregate principal amount of the Notes at the time outstanding,
evidenced as in the Indenture provided, to execute amendments to the Indenture
or supplemental indentures adding any provisions to or changing in any manner or
eliminating any of the provisions of the Indenture or of any supplemental
indenture or modifying in any manner the rights of the holders of the Notes;

provided, however, that no such amendment or supplemental indenture shall (i)
--------  -------
extend the fixed maturity of any Note, or reduce the rate or extend the time of
payment of interest thereon, or reduce the principal amount thereof or premium,
if any, thereon, or reduce any amount payable on redemption or repurchase
thereof, impair, or change in any respect adverse to the holder of Notes, the
obligation of the Company to repurchase any Note at the option of the holder
upon the happening of a Repurchase Event, or impair or adversely affect the
right of any Noteholder to institute suit for the payment thereof, or change the
currency in which the Notes are payable, or impair or change in any respect
adverse to the Noteholders the right to convert the Notes into Common Stock
subject to the terms set forth in the Indenture, including Section 15.6 thereof,
or subordinate in right of payment the Notes to any other Indebtedness, without
the consent of the holder of each Note so affected, or (ii) reduce the aforesaid
percentage of Notes, the holders of which are required to consent to any such
supplemental indenture, without the consent of the holders of all Notes then
outstanding.

                                      A-5
<PAGE>

     It is also provided in the Indenture that the holders of not less than a
majority in aggregate principal amount of the Notes at the time outstanding may
on behalf of the holders of all of the Notes waive any past default or Event of
Default under the Indenture and its consequences except (i) a default in the
payment of interest or premium, if any, on, or the principal of, the Notes when
due, (ii) a failure by the Company to convert any Notes into Common Stock or
(iii) a default in respect of a covenant or provisions of the Indenture which
under Article XI thereof cannot be modified or amended without the consent of
the holders of all Notes then outstanding.  Any such consent or waiver by the
holder of this Note (unless revoked as provided in the Indenture) shall be
conclusive and binding upon such holder and upon all future holders and owners
of this Note and any Notes which may be issued in exchange or substitution
hereof, irrespective of whether any notation thereof is made upon this Note or
such other Notes.

     No reference herein to the Indenture and no provision of this Note or of
the Indenture shall impair the obligation of the Company, which is absolute and
unconditional, to pay the principal of, premium, if any, and interest on this
Note as and when the same shall become due and payable in accordance with the
terms herein.

     Interest on the Notes shall be computed on the basis of a 360-day year
comprised of twelve 30-day months.

     The Notes are issuable in registered form without coupons in denominations
of $1,000 principal amount and integral multiples thereof.  At the office or
agency of the Company referred to on the face hereof, and in the manner and
subject to the limitations provided in the Indenture, without payment of any
service charge but with payment of a sum sufficient to cover any tax,
assessments or other governmental charges that may be imposed in connection with
any registration or exchange of Notes, Notes may be exchanged for a like
aggregate principal amount of Notes of other authorized denominations.

     The Company may, at its option, redeem all or any part of the Notes on any
date prior to maturity, upon mailing a notice of such redemption, and at a
redemption price equal to $1,000 per $1,000 principal amount of the Notes to be
redeemed, plus accrued and unpaid interest, if any, to, but excluding, the date
of redemption, provided, however, that, prior to August 28, 2004, the Company
shall only have such right of redemption if (1) the Closing Price per share of
the Company's Common Stock has exceeded 200% of the Conversion Price then in
effect (not including the effect of any adjustment to the Conversion Price made
pursuant to Section 15.11 of the Indenture) for at least 20 Trading Days within
a period of 30 consecutive Trading Days, and (2) within 10 days following the
Determination Period, the Company mails to holders the notice required pursuant
to Section 3.2 (the date of such notice, the "Notice Date"), and provided,
further, that, prior to the last date on which the shelf registration statement
covering resales of the Notes and the Common Stock issuable upon conversion of
the Notes is required to remain effective pursuant to the Registration Rights
Agreement, such shelf registration statement is effective and available for use
at all times during the period beginning 30 days prior to the Notice Date and
ending on the earlier of the redemption date or the last date on which the Shelf
Registration Statement is required to remain effective and available pursuant to
the Registration Rights Agreement, and is expected to remain effective and
available for use until the earlier of 30 days following the redemption date or
the last date on which the Shelf Registration Statement is required to remain

                                      A-6

<PAGE>

effective pursuant to the Registration Rights Agreement.  If the Company
exercises such right of redemption prior to August 28, 2002, the Company shall
make an additional payment in cash to holders of the redeemed Notes with respect
to the Notes called for redemption, in an amount equal to $70 per each $1,000
principal amount of the Note, less the amount of any interest actually paid on
such Notes prior to the date of notice of redemption is mailed.  The Company
shall make this additional payment on all Notes called for redemption prior to
August 28, 2002, including any Notes converted after the date the notice of
redemption is mailed and before the provisional redemption date.

     If such notice of redemption has been given as provided in the Indenture,
the Notes or portion of Notes called for redemption shall, unless converted into
Common Stock pursuant to the terms of the Indenture, become due and payable on
the date and at the place or places stated in such notice at the applicable
redemption price, together with the Provisional Payment, if any, and interest
accrued to, but excluding, the date fixed for redemption, and on and after such
date (unless the Company shall default in the payment of such Notes at the
redemption price, together with the Provisional Payment, if any, and interest
accrued to, but excluding, said date) interest on the Notes or portion of Notes
so called for redemption shall cease to accrue and such Notes shall cease after
the close of business on the Business Day next preceding the date fixed for
redemption to be convertible into Common Stock and, except as provided in
Sections 8.5 and 13.4 of the Indenture, to be entitled to any benefit or
security under the Indenture, and the holders of such Notes shall have no right
in respect of such Notes except the right to receive the redemption price and
unpaid interest to, but excluding, the date fixed for redemption.  On
presentation and surrender of such Notes at a place of payment specified in such
notice, such Notes or the specified portions thereof to be redeemed shall be
paid and redeemed by the Company at the applicable redemption price, together
with the Provisional Payment, if any, and interest accrued thereon to, but
excluding, the date fixed for redemption; provided that, if the applicable
                                          --------
redemption date is an interest payment date, the semi-annual payment of interest
becoming due on such date shall be payable to the holders of such Notes
registered as such on the relevant record date subject to the terms and
provisions of Section 2.3 of the Indenture.

     The Notes are not subject to redemption through the operation of any
sinking fund.

     Upon the occurrence of a "Repurchase Event," the Noteholder has the right,
at such holder's option, to require the Company to repurchase all or any portion
of such holder's Notes on the 40th calendar day (or, if such 40th day is not a
Business Day, the next succeeding Business Day) after notice of such Repurchase
Event at a price equal to 110% of the principal amount of the Notes such holder
elects to require the Company to repurchase, together, in each case, with
accrued interest to the date fixed for repurchase; provided that if such
                                                   --------
repurchase date is August 15 or February 15, then the interest payable on such
date shall be paid to the holder of record of the Note on the next preceding
August 15 or February 15, respectively.  The Company or, at the written request
of the Company, the Trustee shall mail to all holders of record of the Notes a
notice of the occurrence of a
                                      A-7

<PAGE>

Repurchase Event and of the repurchase right arising as a result thereof on or
before the tenth (10th) calendar day after the occurrence of such Repurchase
Event. If a redemption date pursuant to Article III of the Indenture shall occur
prior to any repurchase date established pursuant to a Company Notice under
Section 16.2 of the Indenture, provided that the Company shall have deposited or
set aside an amount of money sufficient to redeem such Notes as set forth in
Section 3.2 of the Indenture on or before such repurchase date, all such Notes
shall be redeemed pursuant to Article III of the Indenture and the repurchase
rights under Article XVI of the Indenture shall have no effect.

     Subject to the provisions of the Indenture, the holder hereof has the
right, at its option, at any time following the date of original issuance of the
Notes and prior to the close of business on August 15, 2006, (except that, with
respect to any Note or portion of a Note that shall be called for redemption,
such right shall terminate, except as otherwise provided in the Indenture, at
the close of business on the Business Day next preceding the date fixed for
redemption unless the Company shall default in payment due upon redemption), to
convert the principal hereof or any portion of such principal which is $1,000 or
an integral multiple thereof, into that number of fully paid and non-assessable
shares of the Company's Common Stock, as said shares shall be constituted at the
date of conversion, obtained by dividing the principal amount of this Note or
portion thereof to be converted by the conversion price of $6.73 or such
conversion price as adjusted from time to time as provided in the Indenture,
upon surrender of this Note, together with a conversion notice as provided in
the Indenture and this Note, to the Company at the office or agency of the
Company maintained for that purpose in the Borough of Manhattan, The City of New
York, or at any other office or agency permitted by the Indenture, and, unless
the shares issuable on conversion are to be issued in the same name as this
Note, duly endorsed by, or accompanied by instruments of transfer in form
satisfactory to the Company duly executed by, the holder or by his duly
authorized attorney.  Copies of such notice shall also be sent via facsimile to
the Company, attention General Counsel ((650) 519-5333) and Latham & Watkins,
attention John Donohue ((650) 463-2600).  The Company shall pay in cash, on this
Note or portion thereof surrendered for conversion during the period from the
close of business on any interest payment date to which interest has been fully
paid through the close of business on the Business Day preceding the record date
for the next such interest payment date, accrued and unpaid interest, if any,
to, but excluding, the date of conversion.  Any such payment of interest shall
be made with ten (10) Business Days after the Conversion Date.  Notwithstanding
the foregoing, if this Note shall be surrendered for conversion during the
period from the close of business on any record date for any interest payment
date through the close of business on the Business Day next preceding such
interest payment date, this Note (unless the Note or the portion thereof being
converted shall have been called for redemption pursuant to a redemption notice
mailed to the Noteholders in accordance with Section 3.2 of the Indenture or
shall have become due prior to such interest payment date as a result of a
Repurchase Event) must be accompanied by payment in New York Clearing House
funds or other funds acceptable to the Company, of an amount equal to the
interest otherwise payable on such interest payment date on the principal amount
being converted; provided, however, that no such payment need be made if there
                 --------  -------
shall exist at the time of conversion a default in the payment of interest on
the Notes.  No fractional shares of Common Stock will be issued upon any
conversion, but an adjustment in cash will be paid to the holder, as provided

                                      A-8
<PAGE>

in the Indenture, in respect of any fraction of a share which would otherwise be
issuable upon the surrender of any Note or Notes for conversion.

     In addition to any adjustments to the Conversion Price required to be made
pursuant to Section 15.5 of the Indenture, the Conversion Price (1) shall be
adjusted on the date which is the earlier of (A) the date by which the Company
is required to have had the Shelf Registration Statement declared effective by
the Securities and Exchange Commission or be subject to Liquidated Damages under
the Registration Rights Agreement or (B) two calendar days after the date on
which the Commission declares effective the Shelf Registration Statement (the
earlier of such date, the "Registration Date"), if the Current Market Price on
the Registration Date is less than the Conversion Price otherwise in effect on
the Registration Date, to the greater of such Current Market Price or 75% of the
Benchmark Price and (2) shall be adjusted on August 23, 2002 (the "August 23,
2002 Date" and, together with the Registration Date, the "Adjustment Date"), if
the Current Market Price on the August 23, 2002 Date is less than the Conversion
Price otherwise in effect on the August 23, 2002 Date, to the greater of such
Current Market Price or 75% of the Benchmark Price, which Benchmark Price is
subject to adjustment as provided in the Indenture.

     In addition to any adjustment to the Conversion Price required to be made
pursuant to Section 15.5, Section 15.6 or Section 15.11(a) of the Indenture, the
Conversion Price shall be adjusted in accordance with Section 15.11(b) of the
Indenture.

     In connection with any redemption of Notes, the Company may arrange for the
purchase and conversion of any Notes not converted prior to the expiration of
such conversion right by an agreement with one or more investment bankers or
other purchasers to purchase such Notes by paying to the Trustee in trust for
the Noteholders, on or before the date fixed for redemption, an amount not less
than the applicable redemption price, together with the Provisional Payment, if
any, and interest accrued to the date fixed for redemption, of such Notes.

     Upon due presentment for registration of transfer of this Note and any
other documents as may be required to be delivered by the Indenture at the
office or agency of the Company in the Borough of Manhattan, The City of New
York, or at any other office or agency permitted by the Indenture, a new Note or
Notes of authorized denominations for an equal aggregate principal amount will
be issued to the transferee in exchange thereof, subject to the requirements and
limitations provided in the Indenture, without charge except for any tax or
other governmental charge imposed in connection therewith.

     The Company, the Trustee, any authenticating agent, any paying agent, any
conversion agent and any Note registrar may deem and treat the registered holder
hereof as the absolute owner of this Note (whether or not this Note shall be
overdue and notwithstanding any notation of ownership or other writing hereon),
for the purpose of receiving payment hereof (including Liquidated Damages to the
extent accrued but unpaid), or on account hereof, for the conversion hereof and
for all other purposes; and neither the Company nor the Trustee nor any other
authenticating agent nor any paying agent nor any other conversion agent nor any
Note registrar shall be affected by any notice to the contrary.  All such
payments so made to, or upon the order of, such registered holder for the time

being shall be valid, and, to the extent of the sum or sums so paid, effectual
to satisfy and discharge the liability for monies payable on this Note.

     No recourse for the payment of the principal of or any premium or interest
on this Note (including Liquidated Damages, if any), or for any claim based
hereon or otherwise in respect hereof, and no recourse under or upon any
obligation, covenant or agreement of the Company in the Indenture or any
indenture supplemental thereto or in any Note, or because of the creation of any
indebtedness represented thereby, shall be had against any incorporator,
stockholder, employee, agent, officer, director or subsidiary, as such, past,
present or future, of the Company or of any successor corporation, either
directly or through the Company or any successor corporation, whether by virtue
of any constitution, statute or rule of law or by the enforcement of any
assessment or penalty or otherwise, all such liability being, by the acceptance
hereof and as part of the consideration for the issue hereof, expressly waived
and released.

                   FORM OF TRANSFER LETTER OF REPRESENTATIONS

                           (TO BE DELIVERED BY HOLDER
                    UPON CERTAIN TRANSFERS OF NOTES WITHOUT
                       EFFECTIVE REGISTRATION STATEMENT)

     We are delivering this letter in connection with the sale or transfer to us
of Notes (as defined in the Indenture, dated as of August 28, 2001, between TiVo
Inc., a Delaware corporation (the "Company") and The Bank of New York, a New
York banking corporation (the "Trustee")) other than pursuant to a registration
statement that has been declared effective under the Securities Act of 1933, as
amended (the "Securities Act").

     We hereby confirm that:

          (i) we are an "accredited investor" within the meaning of Rule
     501(a)(1),(2), (3), (5), (6) or (7) under the Securities Act;

          (ii) any purchase or receipt of the Notes by us will be for investment
     purposes and for our own account, not as a nominee or agent;

          (iii)  we have such knowledge and experience in financial and business
     matters that we are capable of evaluating the merits and risks of
     purchasing or receiving the Notes;

          (iv) we do not have need for liquidity in our investment in the Notes,
     we have the ability to bear the economic risks of our investment in the
     Notes for an indefinite period of time and we are able to afford the
     complete loss of our investment in the Notes;

          (v) we are not acquiring the Notes with a view to any distribution
     thereof in a transaction that would violate the Securities Act or the
     securities laws of any State of the United States or any other applicable
     jurisdiction, and we have no present intention of selling, granting any
     participation in, or otherwise distributing the same;

          (vi) we have had access to such information regarding the Company
     necessary in order for us to make an informed decision and any such
     information which we have requested have been made available for us or our
     attorney, accountant, or advisor; and

          (vii)  we or our attorney, accountant, or advisor have had a
     reasonable opportunity to ask questions of and receive answers from a
     person or persons acting on behalf of the Company concerning the business,
     management and financial affairs of the Company and the terms and
     conditions of the acquisition by us of the Notes and all such questions
     have been answered to our full satisfaction, and we have acquired
     sufficient information about the Company to make an informed and
     knowledgeable decision to acquire the Notes.

                                      B-1

<PAGE>

     We understand that the Notes have not been registered under the Securities
Act, and we agree, on our own behalf and on behalf of each account for which we
acquire any Notes, that such Notes may be offered, resold, pledged or otherwise
transferred only (i) in accordance with an exemption from the registration
requirements of the Securities Act, (ii) to the Company or (iii) pursuant to an
effective registration statement, and, in each case, in accordance with any
applicable securities laws of any State of the United States or any other
applicable jurisdiction.  We agree that we will furnish the Company and the
Trustee an opinion of counsel, if the Company so requests, that the foregoing
restrictions on transfer have been complied with.  We understand that the
Trustee will not be required to accept for registration of transfer any Notes,
except upon presentation of evidence satisfactory to the Company, including an
opinion of counsel if the Company so requests, that the foregoing restrictions
on transfer have been complied with.

     We acknowledge that the Company and others will rely upon our
confirmations, acknowledgements and agreements set forth herein, and we agree to
notify you promptly in writing if any of our representations or warranties
