"Agreement"), by and between SAVVIS COMMUNICATIONS CORPORATION, a Delaware
corporation (the "Company") and REUTERS HOLDINGS SWITZERLAND SA, a societe
anonyme organized under the laws of Switzerland (the "Purchaser").

         WHEREAS, the Company desires to sell to the Purchaser, and the
Purchaser desires to purchase from the Company, on the terms and subject to the
conditions set forth herein, the principal amount of 12% Convertible Senior
Secured Notes of the Company set forth opposite the Purchaser's name on Schedule
I hereto, in substantially the form of Exhibit A hereto (together with the notes
to be issued as payment-in-kind interest thereunder, the "Notes");

         WHEREAS, in order to induce the Purchaser to purchase the Notes, the
Company has agreed to grant to the Purchaser certain registration rights with
respect to the shares of the Company's Common Stock, $.01 par value ("Common
Stock") issuable upon conversion of the Notes (the "Conversion Shares") or upon
conversion of preferred stock of the Company issuable upon conversion of the
Notes as set forth herein; and

         WHEREAS, the Purchaser desires to enter into this Agreement to acquire
the Notes on the terms and conditions set forth herein.

         NOW, THEREFORE, in consideration of the mutual promises,
representations, warranties, covenants and conditions set forth in this
Agreement, the parties to this Agreement mutually agree as follows:


                                   ARTICLE I

                      Authorization and Sale of the Notes.

         SECTION 1.01. Authorization. The Company has authorized the sale and
issuance of the Notes pursuant to the terms of this Agreement.

         SECTION 1.02. Sale of Notes.

         (a)      From the date of this Agreement and on the third business day
prior to the first business day of each calendar month hereafter through and
including August 1, 2001 (subject to extension pursuant to Section 1.02(c)
hereof), the Company may deliver to the Purchaser, prior to 10:00 am on such
date, a funding request notice (a "Funding Request") consisting of the
following: (i) a request for a certain sum of funds not to exceed, for each
calendar month, the amount for such month set forth on Schedule I, (ii) a
statement that such funds shall be used to pay expenses of the Company and its
subsidiaries in accordance with a cash flow projection of the Company through
August 31, 2001, to be provided to the Purchaser on the date of this Agreement
(including the supplement to such projections to be delivered to the Purchaser
no later than August 1, 2001 covering the cash flow projections of the Company
through October 21, 2001, the "Cash Flow Projection"), (iii) confirmation that
the representations and warranties of the Company contained in Article II hereof
are true and correct in all material respects as of the date of such Funding
Request, except in any such case that would not have a Material Adverse Effect
(as defined in Section 2.01 herein), and that the



                                       2
<PAGE>

Company has fulfilled all conditions and performed all of its obligations
hereunder with respect to such Funding Request, (iv) confirmation that no Event
of Default (as defined in the Notes) has occurred and is continuing, or is about
to occur to the best of the Company's knowledge with respect to Notes
outstanding, and (v) the proposed Closing Date for the delivery of the requested
funds, which date shall not be earlier than the third business day after the
date of such Funding Request. Each Funding Request shall be for an amount up to
the proposed Maximum Funding Amount for such month set forth immediately
opposite Purchaser's name and below such month on attached Schedule I, and in no
event may the aggregate amount of all Funding Requests exceed the total purchase
price for all Notes set forth on Schedule I.

         (b)      Upon receipt of a Funding Request in proper form as set forth
pursuant to Section 1.02(a) above, subject to Article VI hereof, the Purchaser
shall then purchase Notes in satisfaction of the Funding Request for the
aggregate principal amount of Notes requested (the "Purchase Price") at a
Closing (as defined below) and notify the Company of the Closing Date (as
defined below) of such purchase, which shall not be later than the third
business day following receipt of the Funding Request by the Purchaser provided,
however, that the first Closing (the "Initial Closing") shall take place on the
date hereof or as soon as practicable hereafter (such date, the "Initial Closing
Date").

         (c)      In the event that the Closing (as defined in the Bridge
Purchase Agreement, the "Bridge Purchase Agreement Closing") pursuant to the
purchase agreement (the "Bridge Purchase Agreement") between Reuters America
Inc. ("Reuters") and Bridge Information Systems, Inc. ("Bridge"), providing for
the acquisition of certain of the assets of Bridge by Reuters, has not been
consummated and the Bridge Purchase Agreement has not been terminated by 11:59
p.m., New York time, on August 31, 2001, the Company may deliver a Funding
Request pursuant to the terms of Section 1.02(a) hereof on September 1, 2001 and
a Closing will occur, subject to satisfaction of all applicable conditions of
Section 6.02 hereof, on September 4, 2001, and, if the Bridge Purchase Agreement
Closing has not been consummated and the Bridge Purchase Agreement has not been
terminated by 11:59 p.m., New York time, on September 30, 2001, the Company may
deliver a Funding Request pursuant to the terms of Section 1.02(a) hereof on
October 1, 2001 and a Closing will occur, subject to satisfaction of all
applicable conditions of Section 6.02 hereof, on October 1, 2001, for up to the
amounts set forth on Schedule I for such months.

         (d)      Notwithstanding the foregoing, from the date of this Agreement
through October 31, 2001, in the event the Company proposes to execute any
capital-raising or financing transaction involving an investment in securities
of the Company, the Purchaser shall receive notice of such transaction,
summaries of its principal terms and copies of all documents related to such
transaction at the same time and in the same manner as such materials are
provided to potential participants therein. The Purchaser shall have the right
to participate in such transaction on the same terms as the other participants
therein, for an amount up to the Purchaser's unfunded Maximum Funding Amount set
forth opposite the Purchaser's name on attached Schedule I in satisfaction and
release of the Purchaser's funding obligation with respect to the amount of such
participation in the purchase of Notes hereunder.

         SECTION 1.03. Closings; Deliveries.

         (a)      Closing. Except as contemplated pursuant to Section 1.04(b)
hereof, the closing of the purchase and sale of Notes pursuant to a Funding
Request shall take place from time to time (each such date of Closing, a
"Closing Date") in one or more closings (each, a "Closing") by the Purchaser
pursuant to Section 1.02 hereof, provided that the satisfaction (or waiver) of
all the conditions herein have been satisfied, at 10:00 a.m. New York time on
the date of such Closing, at the offices of Hogan & Hartson L.L.P., 885 Third
Avenue, 26th Floor, New York, New York 10022, or at such other time and place as
the Company and the Purchaser may agree. The Closing may be accomplished by
facsimile transmission to the respective offices of counsel for the parties
hereto of the requisite documents, duly executed where required, with originals
to be delivered by overnight courier service on the next business day following
the Closing.

         (b)      Closing Deliveries. At each Closing, subject to the terms and
conditions hereof, the Company will deliver to the Purchaser a Note or Notes,
executed by the Company evidencing an obligation by the Company to pay a
principal amount equal to the Purchase Price, in such denominations and in such
name or names as the Purchaser may designate by notice to the Company, dated the
date of the Closing, against payment of the Purchase Price therefor by wire
transfer in immediately available funds to an account specified by the Company.
Such Purchase Price paid at the Closing shall be delivered and accepted as full
and complete payment against the Notes.

         (c)      Grant of Security. Simultaneous with the execution and
delivery of this Agreement, as security for the amounts owed or to be owed
evidenced by the Notes, the Company's subsidiary will execute the Deed (as
defined in Section 2.04(a)).

         SECTION 1.04. Description of the Notes.

         (a)      Conversion of Notes into Common Stock. From and after the date
of issuance of each Note, subject to Section 1.04(b) below, all or a portion of
the principal amount of the Notes shall, at any time and at the option of the
Purchaser, be convertible into a number of shares of Common Stock, calculated by
dividing the portion of the principal amount of such Notes to be converted
(together with any accrued and unpaid interest on such portion of the principal
amount) by (i) for Notes issued pursuant to the initial Closing, $1.35 and (ii)
for Notes issued pursuant to subsequent Closings, the closing bid price (the
"Closing Bid") of the Common Stock on the Nasdaq Stock Market for the trading
day immediately preceding the date of execution of the Network Services
Agreement Term Sheet (as defined in Section 6.02(a)(vi)) (in each case, subject
to equitable adjustment for stock splits, stock dividends, recapitalizations,
reorganizations or other similar events, the "Common Stock Conversion Price")
with the proportional value of any fractional shares resulting therefrom paid by
the Company in cash to the Purchaser upon conversion; provided, however, that
with respect to clause (ii) of this sentence, if the Closing Bid is lower than
$1.35, the Common Stock Conversion Price shall be $1.35, and if the Closing Bid
is greater than $1.92, the Common Stock Conversion Price shall be $1.92. The
Purchaser will give the Company at least 10 business days notice of its
intention to



                                       4
<PAGE>

convert all or a portion of the principal amount of the Notes into Common Stock,
except if such conversion follows a notice of prepayment pursuant to Section
1.04(d) hereof. The Company shall present and deliver certificates evidencing
the proper number of shares of Common Stock to the Purchaser, in such
denominations and in such name or names as the Purchaser may designate by notice
to the Company, to the Purchaser, at a time and place mutually agreeable to the
Purchaser and the Company, in exchange for delivery of its Note or Notes to the
Company. Upon receipt of such Note in exchange for such certificate or
certificates of Common Stock, the Company shall cancel and destroy such Note or
Notes, and such Note or Notes shall thereafter be null, void and of no effect.
If any of the principal amount of any Note tendered to the Company pursuant to
this Section 1.04(a) shall remain unconverted and outstanding following the
issuance of such Common Stock, the Company shall execute and deliver to the
Purchaser at the same time and in the same manner as the certificate evidencing
the Purchaser's Common Stock is delivered, a replacement note that shall be
identical in all respects as the Note or Notes tendered to the Company, except
that the principal amount shall be reduced by the principal amount converted to
Common Stock. Any Notes issued pursuant to a Funding Request that is delivered
after the automatic conversion of a previously-issued Note pursuant to Section
1.04(b) hereof shall be convertible, at the Purchaser's option, into Purchaser
Conversion Preferred (as defined below).

         (b)      Automatic Conversion of Notes into Preferred Stock.
Simultaneous with the Company raising an aggregate of $50,000,000 (the
"Conversion Amount") in cash through the issuance of convertible preferred stock
prior to the Maturity Date (as defined below), excluding the Notes and PIK
Notes, but including shares issued upon conversion of up to $20,000,000
aggregate principal amount of the Company's 10% Convertible Senior Secured Notes
due February 20, 2006 issued to affiliates of Welsh, Carson, Anderson & Stowe
("Welsh Carson") (excluding any notes issued to Welsh Carson in kind for
interest on such notes), all of the principal amount of the Notes then
outstanding, together with any PIK Notes (as defined below), Notes then-payable
in kind for accrued and unpaid interest as of such date and Notes to be
purchased on such date by the Purchaser, subject to satisfaction of all
applicable conditions set forth in Section 6.02 herein, at a special Closing
with a Purchase Price equal to the difference between $30,000,000 and the
aggregate Purchase Price paid by the Purchaser pursuant to all Closings
completed pursuant to this Agreement as of such date (it being understood that
on such date, the Purchaser shall deliver such Purchase Price by wire transfer
of immediately available funds to the Company), shall be converted into a number
of shares of convertible preferred stock ("Purchaser Conversion Preferred")
having the same rights, preferences, privileges and restrictions as shares
issued (the "Recent Equity Financing Shares") pursuant to the Company's most
recent preferred stock financing (the "Recent Equity Financing"), except that
the initial conversion price of such Purchaser Conversion Preferred shall be the
lesser of (i) the initial conversion price of the Recent Equity Financing
Shares, (ii) the initial conversion price of shares issued pursuant to any
financing which comprises a portion of the Conversion Amount (excluding shares
issued upon conversion of the notes previously issued to Welsh Carson referred
to above), and (iii) the Common Stock Conversion Price. The Purchaser Conversion
Preferred shall be of the same class, but separate series, as the Recent Equity
Financing Shares. The proportional value of any fractional shares resulting from
the issuance of Purchaser Conversion Preferred shall be paid by the Company in
cash to the Purchaser. Notwithstanding the foregoing, the following actions by
the Company shall not be aggregated in calculating the Conversion Amount: (i)
the issuance of any shares of Common Stock pursuant to a stock option



                                       5
<PAGE>

plan approved by the Company's Board of Directors, (ii) the issuance of stock,
warrants or other securities or rights to persons or entities with which the
Company has bona fide business relationships provided such issuances are for
other than primarily equity financing purposes, provided, that in any such case
(involving the foregoing clauses (i) or (ii)) such issuance has been approved by
a majority of the members of the Company's Board of Directors. The Company will
provide the Purchaser with at least 10 business days notice in advance of an
expected closing of an equity financing which will result in the raising of the
Conversion Amount, noting the time and place of such event. The Company shall
present and deliver certificates evidencing the proper number of Purchaser
Conversion Preferred to the Purchaser, in such denominations and in such name or
names as the Purchaser may designate by notice to the Company, to Purchaser at
the closing of the Recent Equity Financing in exchange for delivery of its Notes
to the Company. Upon receipt of such Notes in exchange for such certificate or
certificates of stock evidencing the proper number of Purchaser Conversion
Preferred, the Company shall cancel and destroy such Note or Notes, and such
Note or Notes shall thereafter be null, void and of no effect. An opinion or
opinions of counsel substantially similar to the opinions to be rendered
pursuant to Section 6.01(a)(vi) hereof, reasonably satisfactory to the
Purchaser, will be provided regarding the issuance of the Purchaser Conversion
Preferred upon the issuance of such securities.

         (c)      Redemption.

                  (i)      At Maturity. On May 1, 2005 (the "Maturity Date"),
all of the outstanding principal amount (together with any accrued and unpaid
interest on the principal amount) of the Notes shall be due and payable.

                  (ii)     Upon Change of Control. At any time that Notes are
outstanding, the Company shall notify the Purchaser at least 10 business days
prior to a record date of a transaction which would result in a Change of
Control (as defined in the Notes) of the Company. Upon receipt of such notice,
the Purchaser shall have the right to require the Company (i) to redeem any or
all of the Notes, including the PIK Notes (as defined below), at a cash price
equal to 100% of the principal amount of such Notes, plus all accrued and unpaid
interest and the Applicable Premium Amount (as defined in the Notes) as of the
effective date of the Change of Control, or (ii) to convert the principal amount
of any or all Notes (at the Purchaser's option), including the PIK Notes and the
Applicable Premium Amount (as defined in the Notes), into shares of Common
Stock, determined by dividing the aggregate principal amount of such Notes to be
converted by the Common Stock Conversion Price, with the proportional value of
any fractional shares resulting therefrom paid by the Company in cash to the
Purchaser.

         (d)      Prepayment. From and after the first anniversary of the final
Closing, the Company shall have the right to prepay all, but not less than all,
of the Notes in one transaction, with all accrued and unpaid interest to the
date of repayment at any time without premium or penalty. The Company shall
notify the Purchaser of its intent to prepay the principal amount of the Notes
at least 10 business days prior to the date of such prepayment. The Purchaser
shall have the right at any time prior to the third business day prior to the
date of prepayment to convert its Notes pursuant to Section 1.04(a) hereof.



                                       6
<PAGE>

         (e)      Interest.

                  (i)      Payment. From and after the issuance of Notes,
holders of record of the Notes shall be entitled to receive interest at a rate
of 12% per annum, compounded and payable quarterly, on the principal amount of
the Notes including any issued and outstanding PIK Notes (as defined below).
Until August 1, 2004 (the "PIK Crossover Date"), at the discretion of the
Company, any and all interest payments are payable, from the date of issuance of
such Notes in the form of additional Notes ("PIK Notes") with a face amount
equal to the interest owed at that time, in lieu of cash. From and after the PIK
Crossover Date, holders of record of the Notes shall be entitled to receive
interest at a rate of 12% per annum, compounded and payable quarterly, on the
principal amount of the Notes, in cash only, the first of such payments due on
the last day of the first calendar quarter after the PIK Crossover Date. Any
payment of interest covering a period which includes the PIK Crossover Date
shall be payable, for the portion of such period before the PIK Crossover Date,
in PIK Notes. When issued, the PIK Notes will have the same rights and
privileges as the Notes issued at any Closing.

                  (ii)     Default in Payment. Interest on the Notes, including
PIK Notes, if issued, shall accrue from and after the date of initial issuance
thereof. To the extent that interest remains unpaid ten (10) business days after
the applicable interest payment date, interest shall accrue on the Notes at a
rate of 14% per annum until paid and shall be a continuing obligation of the
Company.


                                   ARTICLE II

                  REPRESENTATIONS AND WARRANTIES OF THE COMPANY

         The Company represents and warrants to Purchaser as of the date hereof
and on the Closing Date, as follows:

         SECTION 2.01. Organization and Qualification. The Company is a
corporation validly existing and in good standing under the laws of the State of
Delaware and has all requisite corporate power and authority to own or lease and
operate its properties and assets and to carry on its business as it is now
being conducted. The Company is duly qualified as a foreign corporation to do
business, and is in good standing, in each jurisdiction in which the character
of its properties owned or leased or the nature of its activities makes such
qualification necessary, except where the failure to be so qualified would not
have a material adverse effect on the properties, assets, financial condition,
operating results, business or prospects of the Company and its subsidiaries,
taken as a whole (a "Material Adverse Effect").

         SECTION 2.02. Subsidiaries. Except for the Subsidiaries disclosed in
the Company SEC Filings (as defined in Section 2.08), the Company does not own,
beneficially or of record, directly or indirectly, any capital stock or other
ownership interest in any other Person. SAVVIS Communications Corporation, a
Missouri corporation ("SAVVIS Missouri") is a corporation validly existing and
in good standing under the laws of Missouri. Global Network Assets, LLC, a
Delaware limited liability company ("Global LLC"), is a limited liability
company, duly formed, validly existing and in good standing under the laws of
Delaware. Each of SAVVIS Missouri and Global LLC has all requisite power and
authority to own or lease and



                                       7
<PAGE>

operate its properties and assets and to carry out its business as it is now
being conducted. Each of SAVVIS Missouri and Global LLC is duly qualified as a
foreign corporation to do business, and is in good standing, in each
jurisdiction in which the character of its properties owned or leased or the
nature of its activities makes such qualification necessary, except where the
failure to be so qualified would not have a Material Adverse Effect. As used in
this Agreement, (i) "Person" means any corporation, partnership, limited
liability company, trust, joint venture or other entity and (ii) "Subsidiary"
means, with respect to any Person, any corporation, association or other
business entity of which more than 50% of the total voting power of shares of
capital stock entitled (without regard to the occurrence of any contingency) to
vote in the election of directors, managers or trustees thereof is at the time
owned or controlled, directly or indirectly, by such Person or one or more of
the other Subsidiaries of such Person or a combination thereof. SAVVIS Missouri
and Global LLC are the Company's only Significant Subsidiaries (as defined in
Rule 1-02(w) of Regulation S-X).

         SECTION 2.03. Capitalization. (a) On the date hereof the authorized
capital stock of the Company consists of 250,000,000 shares of Common Stock and
50,000,000 shares of Preferred Stock, $.01 par value ("Preferred Stock"). As of
the date hereof, 93,844,039 shares of Common Stock and no shares of Preferred
Stock were issued and outstanding, all of which shares of Common Stock were duly
authorized and validly issued and are fully paid and nonassessable.

         (b)      As of the date hereof, except for options granted pursuant to
the Company's stock option plan (the "Stock Option Plan") to purchase an
aggregate 8,852,063 shares of Common Stock and except as set forth on Schedule
2.03(b), no subscription, warrant, option, convertible security, stock
appreciation or other right (contingent or other) to purchase or acquire any
shares of any class of capital stock of the Company or any of its Subsidiaries
is authorized or outstanding, and (except as otherwise expressly contemplated by
this Agreement) there is not any commitment of the Company or any of its
Subsidiaries to issue any shares, warrants, options or other such rights or to
distribute to holders of any class of its capital stock, any evidences of
indebtedness or assets.

         SECTION 2.04. Authorization of Agreements, etc. (a) Except as set forth
on Schedule 2.04 and subject to Section 2.04(b), each of (i) the execution and
delivery by the Company of this Agreement, the Notes, the Amended and Restated
Registration Rights Agreement, dated as of the Closing Date (the "Registration
Rights Agreement"), among the Company and the Purchaser, in substantially the
form attached hereto as Exhibit B, and the Missouri Future Advance Deed of Trust
and Security Agreement, in substantially the form attached hereto as Exhibit C,
dated as of May 11, 2001, between the Company's subsidiary and the Purchaser,
(the "Deed," and collectively with the Registration Rights Agreement, the
"Ancillary Agreements"), (ii) the performance by the Company of its obligations
hereunder and thereunder, and (iii) the issuance, sale and delivery by the
Company of the Notes has been duly authorized by all requisite corporate action
and will not violate any provision of law, any order of any court or other
agency of government, any rule or regulation of the National Association of
Securities Dealers, Inc., the Nasdaq stock market or any rule of any other
securities exchange under which the Company may be subject, the Certificate of
Incorporation or Bylaws of the Company, or any provision of any indenture,
agreement or other instrument to which the Company or any of its properties or
assets is bound, or conflict with, result in a breach of or



                                       8
<PAGE>

constitute (with due notice or lapse of time or both) a default under any such
indenture, agreement or other instrument, or result in the creation or
imposition of any liens, claims, charges, restrictions, rights of others,
security interests, prior assignments or other encumbrances (collectively,
"Claims") in favor of any third Person upon any of the assets of the Company or
any of its Subsidiaries, except that no representation is made as to the
compliance of the indemnification or contribution provisions of the Registration
Rights Agreement with law or public policy.

         (b)      The parties acknowledge that the Board of Directors of the
Company is treating each possible sale of Notes hereunder as a separate
transaction, and has only approved the transactions contemplated by this
Agreement which will not result in the Purchaser, together with its affiliates,
becoming the "beneficial owner" (as defined in Section 203 of the Delaware
General Corporation Law, "DGCL 203") of 15% or more of the outstanding voting
stock of the Company or becoming an "interested stockholder" as defined in such
Section. Any sale of Notes in accordance with Section 1 hereof that would result
in the Purchaser becoming the beneficial owner of 15% or more of the Company's
outstanding voting stock or becoming an interested stockholder (an "Interested
Stockholder Transaction") will require further approval of the Company's Board
of Directors beyond what has been received as of the date of execution of this
Agreement, and nothing herein shall be deemed to constitute a representation by
the Company that any Interested Stockholder Transaction has been approved by its
Board of Directors or an agreement by the Company that any such further approval
will be granted. The parties acknowledge that the Purchaser or an affiliate of
the Purchaser has acquired an option from Bridge to acquire and/or vote shares
of the Company's common stock held by Bridge, which option is limited to the
number of shares as would not at the time make the Purchaser and its affiliates
an interested stockholder under DGCL 203. It is the intention of the parties
that the beneficial ownership by the Purchaser or its affiliates of outstanding
voting stock of the Company under such option will be reduced simultaneously
with Notes being sold hereunder, so that the combined effect of the sale of
Notes and existence of such option will not result in the Purchaser or any of
its affiliates becoming an interested stockholder under DGCL 203, provided,
however, that this sentence shall cease to be of any further force or effect if
the Purchaser hereafter becomes an interested stockholder with the approval of
the Company's Board of Directors. Notwithstanding the foregoing, it is
understood and agreed that no securities will be issued pursuant to this
Agreement, including securities issued upon conversion of securities issued
pursuant to this Agreement, in any form unless such issuance has been approved
by the Board of Directors of the Company. The conversion of any securities
issued hereby into Conversion Shares or Purchaser Conversion Preferred, as
described herein, has been or will be approved by the Board of Directors of the
Company, and the Purchaser (and any successors or assigns) may rely on such
approval in the conversion of such securities. In addition, any adjustment to
the outstanding voting stock of the Company by the Company which would result in
the Purchaser or its affiliates beneficially owning 15% or more of the Company's
outstanding voting stock (determined in accordance with DGCL 203) will be
approved by the Board of Directors of the Company, including for purposes of
DGCL 203.

         (c)      The issuance, sale and delivery of the Notes to the Purchaser
hereunder are not subject to any preemptive rights of stockholders of the
Company or to any right of first refusal or other similar right in favor of any
Person.



                                       9
<PAGE>

         (d)      The Conversion Shares have been duly authorized by the Company
and, when issued in accordance with the provisions of the Notes, will be validly
issued, fully paid and nonassessable shares of Common Stock. The issuance, sale
and delivery of the Conversion Shares to the Purchaser are not and upon
conversion of the Notes will not be subject to any preemptive rights of
stockholders of the Company or to any right of first refusal or other similar
right in favor of any Person.

         SECTION 2.05. Validity. This Agreement has been duly executed and
delivered by the Company and constitutes the legal, valid and binding obligation
of the Company, enforceable against the Company in accordance with its terms.
Each of the Notes and the Ancillary Agreements, when executed and delivered by
the Company as provided in this Agreement, will constitute the legal, valid and
binding obligation of the Company, enforceable against the Company in accordance
with its terms, except that no representation is made as to (i) the
enforceability of the indemnification or contribution provisions of the
Registration Rights Agreement and (ii) the enforceability of this Agreement or
the Registration Rights Agreement to the extent that their enforceability may be
subject to applicable bankruptcy, insolvency, reorganization, moratorium or
similar laws affecting enforceability of creditors' rights generally or by
general equitable principles.

         SECTION 2.06. Governmental Approvals. Subject to the accuracy of the
representations and warranties of the Purchaser set forth in Article III hereof
and except for applicable filings, if any, required by applicable federal and
state securities laws and listing regulations, no registration or filing with,
or consent or approval of, or other action by, any federal, state or other
governmental agency or instrumentality or securities exchange (each, a
"Governmental Authority") is or will be necessary for the valid execution,
delivery and performance of this Agreement, the Ancillary Agreements, or the
issuance and delivery of the Conversion Shares.

         SECTION 2.07. Financial Statements.

         (a)      The Company has furnished to the Purchaser the unaudited
consolidated balance sheet of the Company and its subsidiaries as of March 31,
2001 (the "Interim Balance Sheet") and the related consolidated statements of
operations, stockholders' equity and cash flows for the three months then ended.
All such financial statements (including any related schedules and/or notes)
have been prepared in accordance with generally accepted accounting principles
in the United States ("GAAP") consistently applied and consistent with prior
periods, except for normal year-end adjustments and the absence of footnotes.
Such Interim Balance Sheet fairly presents in all material respects the
consolidated financial position of the Company and its subsidiaries as of its
date, and such statements of operations, stockholders' equity and cash flows
fairly present in all material respects the consolidated results of operations,
stockholders' equity and cash flows of the Company and its subsidiaries for the
three months ended the date of the Interim Balance Sheet.

         (b)      The Company has furnished the Purchaser with the Cash Flow
Projection. The Cash Flow Projection fairly presents, in all material respects,
management's good faith estimate of cash flows and expenses of the Company for
the covered period, is based on assumptions that management believes in good
faith to be appropriate.



                                       10
<PAGE>

         (c)      Except as and to the extent (i) reflected on the Interim
Balance Sheet (including the notes thereto), (ii) incurred since the date of the
Interim Balance Sheet in the ordinary course of business consistent with past
practice, or (iii) set forth on Schedule 2.07 hereto, neither the Company nor
any of its subsidiaries has any material liabilities or obligations of any kind
or nature, whether known or unknown, secured or unsecured, absolute, accrued,
contingent or otherwise, and whether due or to become due, that would be
required to be reflected on a balance sheet, or the notes thereto, prepared in
accordance with GAAP. Except as set forth on Schedule 2.07, since the date of
the Interim Balance Sheet, neither the Company nor any of its subsidiaries has
suffered any Material Adverse Effect.

         SECTION 2.08. SEC Filings. The Company has filed all forms, reports and
documents required to be filed with the Securities and Exchange Commission (the
"SEC") as of the date of this Agreement, and the Company has made available to
the Purchaser, as filed with the SEC, complete and accurate copies of (i) the
Annual Report of the Company on Form 10-K for the year ended December 31, 2000,
and (ii) all other reports, statements and registration statements (including,
but not limited to, Current Reports on Form 8-K and Quarterly Report on Form
10-Q) filed by the Company with the SEC since December 31, 2000, in each case
including, but not limited to, all amendments and supplements (collectively, the
"Company SEC Filings"). The Company SEC Filings (excluding any financial
statements or schedules included therein, which are covered by the
representations and warranties of the Company in Section 2.07(a)) (i) were
prepared in compliance with the requirements of the Securities Act of 1933, as
amended (the "Securities Act"), or the Securities Exchange Act of 1934, as
amended (the "Exchange Act"), and the rules and regulations thereunder, and the
rules and regulations thereunder, as the case may be, and (ii) did not at the
time of filing (or if amended, supplemented or superseded by a filing prior to
the date hereof, on the date of that filing) contain any untrue statement of a
material fact or omit to state a material fact required to be stated therein or
necessary in order to make the statements therein, in light of the circumstances
under which they were made, not misleading.

         SECTION 2.09. Absence of Certain Changes or Events. Except as set forth
on Schedule 2.09 hereto and except as otherwise expressly contemplated by this
Agreement, since the date of the Interim Balance Sheet, neither the Company nor
any of its subsidiaries has (i) issued any stock, bonds or other corporate
securities, (ii) borrowed or refinanced any indebtedness for borrowed money
other than borrowings under the Amended and Restated Credit Agreement dated as
of September 5, 2000 (the "Credit Agreement"), among the Company, Savvis
Communications Corporation, a Missouri Corporation, Nortel Networks Inc., as
Administrative Agent, and the lenders named therein, (iii) discharged or
satisfied any material Claim or incurred or paid any obligation or liability
(absolute or contingent) other than current liabilities shown on the Interim
Balance Sheet and current liabilities incurred since the date of such balance
sheet in the ordinary course of business consistent with past practice, (iv) in
the case of the Company only, declared or made any payment or distribution to
stockholders, or purchased or redeemed any shares of its capital stock or other
securities, or (v) except in connection with this Agreement and the transactions
contemplated hereby, entered into any agreement, letter of intent or similar

<PAGE>

         SECTION 2.10. Actions Pending. Except as set forth in the Company SEC
Filings and as set forth on Schedule 2.10, there is no action, suit,
investigation or proceeding pending or, to the best knowledge of the Company,
threatened against or affecting the Company to which its property is subject,
before any court or by or before any governmental body or arbitration board or
tribunal, which the Company would be required to disclose pursuant to Item 1 of
Part II of Form 10-Q if such Form 10-Q were required to be filed on and as of
the date hereof. For the purposes of this Agreement, the term "best knowledge of
the Company" shall mean the actual knowledge of the executive officers of the
Company.

         SECTION 2.11. Compliance with Law; Permits. Neither the Company nor any
of its subsidiaries is in default in any respect under any order or decree of
any court, governmental authority, arbitrator or arbitration board or tribunal
or under any laws, ordinances, governmental rules or regulations to which the
Company or any of such subsidiaries or any of their respective properties or
assets is subject, except where such default would not have a Material Adverse
Effect. The Company possesses all permits, authorizations, approvals,
registrations, variances and licenses ("Permits") necessary for the Company or
its subsidiaries to own, use and maintain their properties and assets or
required for the conduct of its business in substantially the same manner as it
is currently conducted, except where the failure to possess any such Permit
would not have a Material Adverse Effect. Except to the extent the failure of
any of the following to be correct would not have a Material Adverse Effect,
each Permit is in full force and effect, and no proceeding is pending or, to the
best knowledge of the Company, threatened to modify, suspend, revoke or
otherwise limit any Permit, and no administrative or governmental actions have
been taken or, to the best knowledge of the Company, threatened in connection
with the expiration or renewal of any Permit.

         SECTION 2.12. Contracts. Except as disclosed in the Company SEC Filings
and as set forth on Schedule 2.12, there are no contracts or agreements that are
material to the conduct of the Company's business or to the financial condition
or results of operations of the Company and its subsidiaries, taken as a whole,
that the Company would be required to disclose pursuant to paragraph 10 of Item
601 of Regulation S-K if a Form 10-Q were required to be filed on and as of the
date hereof. Except as set forth on Schedule 2.12, each of the agreements
(collectively, the "Material Agreements") disclosed as an exhibit in the Company
SEC Filings in response to paragraph 10 of Item 601 of Regulation S-K under
which there are continuing rights or obligations is a valid and enforceable
obligation of the Company and, to the best knowledge of the Company, of the
other parties thereto, except where the failure to be valid or enforceable would
not have a Material Adverse Effect and provided that no representation is made
as to the enforceability of such agreements to the extent that their
enforceability may be subject to applicable bankruptcy, insolvency,
reorganization, moratorium or similar laws affecting enforceability of
creditors' rights generally or by general equitable principles. Except as
disclosed on Schedule 2.12, to the best knowledge of the Company, the Company
has not been notified in writing of any claim that any Material Agreement is not
valid and enforceable in accordance with its terms for the periods stated
therein (other than where such enforceability is in violation of public policy
or law), or that there is under any such contract any existing default or event
of default or event that with notice or lapse of time or both would constitute
such a default, except any such failure to be valid or enforceable and any such
defaults that, in the aggregate, would not have a Material Adverse Effect.



                                       12
<PAGE>

         SECTION 2.13. Offering of the Notes. Assuming the accuracy of the
representations and warranties of the Purchaser set forth in Article III hereof,
neither the Company nor any person acting on the Company's behalf has taken or
will take any action (including, but not limited to, any offer, issuance or sale
of any securities of the Company under circumstances which might require the
integration of such transactions with the sale of the Notes under the Securities
Act or the rules and regulations of the SEC thereunder) which would subject the
offering, issuance or sale of the Notes to the Purchaser pursuant to this
Agreement to the registration provisions of the Securities Act.

         SECTION 2.14. Related-Party Transactions. Except (i) as set forth in
the Company SEC Filings, (ii) as set forth on Schedule 2.14, or (iii) as

and receipt by the Purchaser of the Notes being acquired by it hereunder, have
been duly authorized by all requisite action on the part of the Purchaser and
will not violate any provision of law, any order of any court or other agency of
government, the charter or other governing documents of the Purchaser, or any
provision of any indenture, agreement or other instrument by which the Purchaser
or any of the Purchaser's properties or assets are bound, or conflict with,
result in a breach of or constitute (with due notice or lapse of time or both) a
default under any such indenture, agreement or other instrument, or result in

         SECTION 3.03. Validity. This Agreement has been duly executed and
delivered by the Purchaser and constitutes the legal, valid and binding
obligation of such Purchaser, enforceable against the Purchaser in accordance
with its terms. Each of the Ancillary Agreements, when executed and delivered in
accordance with this Agreement, will constitute the legal, valid and binding
obligation of the Purchaser, enforceable against the Purchaser in accordance
with its terms.

         SECTION 3.04. Investment Representations.

         (a)      The Purchaser is acquiring the Notes being purchased by the
Purchaser hereunder for the Purchaser's own account, for investment, and not
with a view toward the resale or distribution thereof.

         (b)      The Purchaser understands that he, she or it, as the case may
be, must bear the economic risk of the Purchaser's investment for an indefinite
period of time, because the Notes and, when issued upon conversion of Notes, the
Conversion Shares are not registered under the Securities Act or any applicable
state securities laws and may not be resold unless subsequently registered under
the Securities Act and such other laws or unless an exemption from such
registration is available.

         (c)      The Purchaser has the ability to bear the economic risks of
the investment in the Notes being purchased hereunder for an indefinite period
of time. The Purchaser further acknowledges that he, she or it, as the case may
be, has received copies of the Company SEC Filings and has had the opportunity
to ask questions of, and receive answers from, officers of the Company with
respect to the business and financial condition of the Company and the terms and
conditions of the offering of the Notes and to obtain additional information
necessary to verify such information or can acquire it without unreasonable
effort or expense.

         (d)      The Purchaser has such knowledge and experience in financial
and business matters that the Purchaser is capable of evaluating the merits and
risks of its investment in the Notes. The Purchaser further represents that he,
she or it, as the case may be, is an "accredited investor" as such term is
defined in Rule 501 of Regulation D of the SEC under the Securities Act with
respect to its purchase of the Notes.

         SECTION 3.05. Governmental Approvals. No registration or filing with,
or consent or approval of, or other action by, any Governmental Authority is or
will be necessary by the Purchaser for the valid execution, delivery and
performance of this Agreement and the Ancillary Agreements.

cost and expense, to compromise or settle such claim, but (ii) the indemnifying
party shall not, without the prior written consent of the party to be
indemnified, settle or compromise any claim or consent to the entry of any

the claimant or the plaintiff to the party to be indemnified a release from all
liability in respect of such claim; and

         SECTION 8.06. Entire Agreement; Assignment. This Agreement (including,
but not limited to, the Schedules and Exhibits thereto) constitutes the entire
agreement of the parties with respect to the subject matter hereof and may not
be amended or modified nor any provisions waived except in a writing signed by

any SEC-recognized trading market or equivalent foreign exchange or trading
market; provided that any such required disclosure shall only be made, to the

Purchaser; or

                  (ii)     by either the Company or the Purchaser if
consummation of the transactions contemplated hereby would violate any
nonappealable final order, decree or judgment of any court or Governmental
Authority having competent jurisdiction.

8.08(a)(ii) hereof shall promptly give notice of such termination to the other
party.

         (b)      If this Agreement is terminated as permitted by this Section
8.08, such termination shall be without liability of either party (or any
stockholder, director, officer, employee, agent, consultant or representative of
such party) to the other parties to this Agreement; provided that if such
termination shall result from the willful (i) failure of either party to fulfill
a condition to the performance of the obligations of the other party, (ii)
failure to perform a covenant of this Agreement or (iii) breach by either party
hereto of any representation or warranty or agreement contained herein, such
party shall be fully liable for any and all losses incurred or suffered by the
other party as a result of such failure or breach. The provisions of Sections

Agreement may be amended or waived if, but only if, such amendment or waiver is
in writing and is signed, in the case of an amendment, by each party to this
Agreement, or in the case of a waiver, by the party against whom the waiver is
to be effective.

         (b)      No failure or delay by any party in exercising any right,
power or privilege hereunder will operate as a waiver thereof, nor will any
single or partial exercise thereof preclude any other or further exercise
thereof or the exercise of any other right, power or privilege, nor will any
waiving of any right power or privilege operate to waive any other subsequent
right, power or privilege. The rights and remedies herein provided will be
cumulative and not exclusive of any rights or remedies provided by law.

         SECTION 8.12. Taxes. Each party hereto acknowledges that it is
responsible for the payment of its own taxes including filing of corresponding
tax returns and submission of any form or other document relating to the

         Agreement.

3.       A mechanics lien for a debt of approximately $73,400 has been filed on

         nonpayment by SAVVIS Missouri relative to certain construction at such

         under its lease at such data center.

4.       Various mechanic's and materialmen's liens have been filed against the
         Hazelwood Data Center in Missouri for a total debt of approximately

         under various network services agreements relating thereto.

         leases of real estate by Company and/or SAVVIS Missouri to the extent
         such event of default or alleged event of default occurred on or prior
         to the date of this Agreement and/or matters under any such leases
         occurring on or prior to the date of this Agreement which, with the
         passage of time, would constitute an event of default or alleged event
         of default under such leases.

12.      The filing of any mechanic's or materialmen's liens against or
         otherwise encumbering any of the Mortgaged Property (as defined in the
         Deed of Trust by SAVVIS Missouri in favor of Purchaser dated as of May
         16, 2001) arising out of the construction by or for the benefit of
         SAVVIS Missouri of the Building (as defined in such Deed of Trust) to
         the extent of any of such construction completed as of the date of this
         Agreement.

13.      Any insolvency of the Company or SAVVIS Missouri (it being understood
         that neither the Company nor SAVVIS Missouri are acknowledging or
         confirming the existence of any such insolvency nor shall they be
         deemed to be waiving any right to dispute any assertion that one or
         either of them were, prior to the date of this Agreement, insolvent).

Neither the Company nor SAVVIS Missouri are acknowledging or admitting the
validity of claims or assertion by any person or entity against the Company
and/or SAVVIS Missouri concerning any of the foregoing matters.

         SAVVIS COMMUNICATIONS CORPORATION, a Delaware corporation (hereinafter
called the "Corporation"), for value received, hereby promises to pay Reuters
Holdings Switzerland SA, or registered assigns (the "Holder"), the principal sum
of ____________________________ ($____________), in a single installment on May
1, 2005 (the "Maturity Date"), or the next preceding Business Day (as defined
below) with interest (computed on the basis of a 360-day year) from the date
hereof on the unpaid principal amount hereof. Such interest shall accrue at the
rate of 12% per annum, compounded on a quarterly basis, payable on the first day
of February, May, August and November of each year (each such day being an
"Interest Payment Date") commencing on August 1, 2001, by, at the option of the
Corporation, (i) the payment of cash to the Holder or, (ii) until August 1,
2004, the issuance of an additional Note or Notes (each a "PIK Note") by the
Corporation in favor of the Holder, in substantially the form hereof, in a
principal amount equal to the interest payable to such holder on such Interest
Payment Date, until the principal amount hereof shall have become due and
payable, whether at maturity or by acceleration or otherwise, and thereafter at
the rate of 14% per annum on any overdue principal amount and (to the extent
permitted by applicable law) on any overdue interest until paid.

         The payment of principal and interest on this Note shall be in such

accrue from the Interest Payment Date in respect of which such PIK Note should
have been issued until repayment in cash of the principal and payment in cash of
all accrued interest in full. Interest shall accrue on this Note such that the
aggregate interest due and payable on the Maturity Date and on each Interest
Payment Date would be the same as if all PIK Notes not issued had been issued in
accordance with the terms of this Note, and the principal payable on the
Maturity Date with respect to this Note shall be an amount equal to the sum of
the principal outstanding hereunder and the aggregate principal which would be
outstanding if the PIK Notes not issued had been issued in accordance with the
terms of this Note.

     such merger is owned of record or beneficially by persons who owned voting
     capital stock of the Corporation immediately prior to such merger or

     the Corporation, (2) immediately after the effective date of such merger or

principal amount hereof together with interest accrued hereon and Applicable
Premium Amount hereon to the date fixed for such prepayment. Notwithstanding the

prepayment, and, unless a notice of conversion delivered pursuant to Section 15
states to the contrary, any notice of conversion given while such a transaction
is pending shall also be conditional upon the closing of such transaction, and
no prepayment shall be required and no conversion shall be effected, unless and
until such transaction is consummated.

overdue installment of interest or overdue Applicable Premium Amount, shall bear

or upon any property, real, personal or mixed, belonging to the Corporation or
any subsidiary, or upon any part thereof by the United States or any State
thereof, as well as all lawful claims for labor, materials and supplies, which,
if unpaid, would become a lien or charge upon such property or any part thereof;
provided, however, that the Corporation shall not be required to pay and
discharge or to cause to be paid and discharged any such tax, assessment,
charge, levy or claim (i) so long as both (x) the Corporation has set aside
adequate reserves for such tax, assessment, charge, levy or claim and (y) the
Corporation shall be contesting the validity thereof in good faith by
appropriate proceedings or the Corporation shall,



                                       5
<PAGE>

in its good faith judgment, deem the validity thereof to be questionable and the
party to whom such tax, assessment, charge, levy or claim is allegedly owed
shall not have made written demand for the payment thereof or (ii) where the
failure to pay or discharge would not have a material adverse effect on the
properties, assets, financial condition, operating results, business or
prospects of the Corporation and its subsidiaries, taken as a whole (a "Material
Adverse Effect").

         (c)      Corporate Existence. The Corporation will do or cause to be
done all things necessary and lawful to preserve and keep in full force and
effect its corporate existence, rights and franchises under the laws of the
United States or any State thereof; provided, however, that nothing in this
subsection (c) shall prevent a consolidation or merger of, or a sale, transfer
or disposition of all or any substantial part of the property and assets of, the
Corporation, or the abandonment or termination of any rights or franchises of
the Corporation, if such abandonment or termination is, in the good faith
business judgment of the Corporation, in the best interests of the Corporation
or would not have a Material Adverse Effect.

         (d)      Maintenance of Property. The Corporation will at all times
maintain and keep, or cause to be maintained and kept, in good repair, working
order and condition all significant properties of the Corporation used in the
conduct of the business of the Corporation, and will from time to time make or
cause to be made all needful and proper repairs, renewals, replacements,
betterments and improvements thereto, so that the business carried on in
connection therewith may be properly and advantageously conducted at all times;
provided, however, that nothing in this subsection (d) shall require the making
of any repair or renewal or the continuance of the operation and maintenance of
any property or the retention of any assets, if such action (or inaction) is, in
the good faith business judgment of the Corporation, in the best interests of
the Corporation or would not have a Material Adverse Effect.

         (e)      Insurance. The Corporation will keep adequately insured, by
financially sound and reputable insurers, all property of a character usually
insured by corporations engaged in the same or a similar business similarly
situated against loss or damage of the kinds customarily insured against by such
corporations and carry, with financially sound and reputable insurers, such
other insurance (including, without limitation, liability insurance) in such
amounts as are available at reasonable expense and to the extent believed
necessary in the good faith business judgment of the Corporation.

         (f)      Keeping of Books. The Corporation will at all times keep
proper books of record and account in which proper entries will be made of its
transactions in accordance with generally accepted accounting principles
consistently applied.

         (g)      Notice of Default. If any one or more events which constitute,
or which with notice or lapse of time or both would constitute, an Event of
Default under Section 11 shall occur, or if the holder of any Note shall demand
payment or take any other action permitted upon the occurrence of any such Event
of Default, the Corporation shall immediately after it becomes aware that any
such event would with or without notice or lapse of time or both constitute such


                                       6
<PAGE>

an Event or that such demand has been made or that any such action has been
taken, give notice to the holder of this Note, specifying the nature of such
event or of such demand or action, as the case may be; provided, however, that
if such event, in the good faith judgment of the Corporation, will be cured
within ten Business Days after the Corporation has knowledge that such event
would, with or without notice or lapse of time or both, constitute such an Event
of Default, no such notice need be given if such Event of Default shall be cured
within such ten-day period.

     available, any material revisions to the Annual Budget;

          (v) Reports. Promptly upon transmission or receipt thereof, copies of
     any filings and registrations with, and reports to or from, the Securities
     and Exchange Commission, or any successor agency, and copies of all
     financial statements, proxy statements, notices and reports as the
     Corporation shall send to its shareholders or to a holder of any
     indebtedness owed by the Corporation in its capacity as such a holder;
     provided, however, that notwithstanding the foregoing, the Corporation will
     not furnish to any Holder any material non-public information regarding the
     Corporation unless such Holder shall have signed a confidentiality
     agreement reasonably acceptable to the Corporation agreeing to maintain
     such information confidential and to refrain from trading in the Common
     Stock until the Corporation has advised such Holder, or such Holder
     otherwise discovers, that such information has ceased to be material or has
     been disclosed to the public.

         10.      MODIFICATION BY HOLDERS; WAIVER. The Corporation may, with the
written consent of the holders of not less than 66 2/3% in principal amount of
the Notes then outstanding, modify the terms and provisions of the Notes or the
rights of the holders of the Notes or the obligations of the Corporation
thereunder, and the observance by the Corporation of any term or provision of
the Notes may be waived with the written consent of the holders of not less than
66 2/3% in principal amount of the Notes then outstanding; provided, however,
that no such modification or waiver shall:

          (a) change the maturity of any Note or reduce the principal amount
     thereof or reduce the rate or extend the time of payment of interest
     thereon or reduce the amount or change the time of payment of premium
     payable on any prepayment thereof without the consent of the holder of each
     Note so affected; or

          (b) give any Note any preference over any other Note; or



                                       8
<PAGE>

          (c) reduce the applicable aforesaid percentages of Notes, the consent
     of the holders of which is required for any such modification.

         Any such modification or waiver shall apply equally to all the holders
of the Notes and shall be binding upon them, upon each future holder of any Note
and upon the Corporation, whether or not such Note shall have been marked to
indicate such modification or waiver, but any Note issued thereafter shall bear
a notation referring to any such modification or waiver. Promptly after
obtaining the written consent of the holders as herein provided, the Corporation
shall transmit a copy of such modification or waiver to all the holders of the
Notes at the time outstanding.

         11.      EVENTS OF DEFAULT. If any one or more of the following events,
herein called "Events of Default," shall occur, for any reason whatsoever, and
whether such occurrence shall, on the part of the Corporation, be voluntary or
involuntary or come about or be effected by operation of law or pursuant to or
in compliance with any judgment, decree or order of a court of competent
jurisdiction or any order, rule or regulation of any administrative or other
governmental authority and such Event of Default shall be continuing:

          (a) default shall be made in the payment of the principal of any Note
     or the premium thereon, if any, when and as the same shall become due and
     payable, whether at maturity or at a date fixed for prepayment or by
     acceleration or otherwise; or

          (b) default shall be made in the payment of any installment of
     interest on any Note according to its terms when and as the same shall
     become due and payable and such default shall continue for a period of 15
     days; or

          (c) (i) commencement of a voluntary case under the federal bankruptcy
     laws (as now or hereafter in effect), (ii) filing a petition seeking to
     take advantage of any other laws, domestic or foreign, relating to
     bankruptcy, insolvency, reorganization, winding-up or composition for
     adjustment of debts, (iii) consenting to or failing to contest in a timely
     and appropriate manner any petition filed against it in an involuntary case
     under such bankruptcy laws or other laws, (iv) applying for or consenting
     to, or failing to contest to, in a timely and appropriate manner, the
     appointment of, or the taking of possession by, a receiver, custodian,
     trustee, or liquidator of itself or of a substantial part of its property,
     domestic or foreign, (v) admitting in writing its inability to pay its
     debts as they become due, (vi) making a general assignment for the benefit
     of creditors, or (vii) taking any corporate action for the purpose of
     authorizing any of the foregoing; or

          (d) the entry of a decree or order by any court of competent
     jurisdiction in respect of the Corporation or any material subsidiary
     granting (i) relief in any involuntary case under the federal bankruptcy
     laws (as now or hereafter in effect) or under any other laws, domestic or
     foreign, relating to bankruptcy, insolvency, reorganization, winding up or
     adjustment of debts, or (ii) appointment of a trustee, receiver, custodian,
     liquidator or the



                                       9
<PAGE>

     like for the Corporation or any material subsidiary or for all or any
     substantial part of their respective assets, domestic or foreign, and such
     case or proceeding shall continue undismissed or unstayed for a period of
     60 consecutive days; or

          (e) (i) a default by the Corporation in any material respect shall
     have occurred in any covenant to which the Corporation is subject in the
     Purchase Agreement or any Ancillary Document (as defined in the Purchase
     Agreement) or (ii) a payment default (other than any payment defaults
     disclosed in the Purchase Agreement including those payment defaults
     related to agreements with which the Company is a party with Nortel
     Networks Inc. or General Electric Capital Corporation (the "Specified
     Defaults"), provided, that such Specified Defaults are waived within 10
     days of the date hereof (or such later date as the Network Services Term
     Sheet is executed) and then only for so long as such waivers shall be in
     effect) shall have occurred or acceleration of the payment of the
     indebtedness (other than acceleration solely in response to any events of
     default disclosed in the Purchase Agreement) shall have been commenced
     under any agreement or document evidencing indebtedness of the Corporation;

then, the holder or holders of at least a majority in aggregate principal amount
of the Notes at the time outstanding may, at its or their option, by written
notice to the Corporation, declare all the Notes to be, and all the Notes shall
thereupon be and become, forthwith due and payable together with interest
accrued thereon without presentment, demand, protest or further notice of any
kind, all of which are expressly waived to the extent permitted by law;
provided, however, that, upon the occurrence and during the continuance of any
of the events specified in subsections (a) or (b) of this Section 11, the holder
of any Note at the time outstanding may, at its option by notice in writing to
the Corporation, declare any Note or Notes then held by it to be, and such Note
or Notes shall thereupon be and become, forthwith due and payable together with
interest accrued thereon without presentment, demand, protest or further notice
of any kind, all of which are expressly waived to the extent permitted by law.
Notwithstanding the foregoing, nothing in this Section 11 shall impair the right
of the holder of this Note to convert all or any portion of this Note into
Common Stock in accordance with the provisions of Section 15 hereof.

         At any time after any declaration of acceleration has been made as
provided in this Section 11, the holders of at least 66-2/3% in principal amount
of the Notes then outstanding may, by notice to the Corporation, rescind such
declaration and its consequences if the Corporation has paid all overdue
installments of interest on the Notes and all principal (and premium, if any)
that has become due otherwise than by such declaration of acceleration; and all
other defaults and Events of Default (other than nonpayments of principal and
interest that have become due solely by reason of acceleration) shall have been
remedied or cured or shall have been waived pursuant to this paragraph;
provided, however, that no such rescission shall extend to or affect any
subsequent default or Event of Default or impair any right consequent thereon.

         Without limiting the foregoing, the Corporation hereby waives any right
to trial by jury in any legal proceeding related in any way to this Note or the
Notes and agrees that any such proceeding may, if the holder so elects, be
brought and enforced in any state or, if



                                       10
<PAGE>

applicable federal court, located in New York City in the Borough of Manhattan
and the Corporation hereby waives any objection to jurisdiction or venue in any
such proceeding commenced in such court. The Corporation further agrees that any
process required to be served on it for purposes of any such proceeding may be
served on it, with the same effect as personal service on it within the State of
Delaware, by registered mail addressed to it at its office or agency set forth
in Section 19 for purposes of notices hereunder.

         12.      SUITS FOR ENFORCEMENT. In case any one or more of the Events
of Default specified in Section 11 of this Note shall happen and be continuing,
the holder of this Note may proceed to protect and enforce its rights by suit in
equity, action at law and/or by other appropriate proceeding, whether for the
specific performance of any covenant or agreement contained in this Note or in
aid of the exercise of any power granted in this Note, or may proceed to enforce
the payment of this Note or to enforce any other legal or equitable right of the
holder of this Note.

         In case of any default under any Note, the Corporation will pay to the
holder thereof such amounts as shall be sufficient to cover the out-of-pocket
costs and expenses of such holder due to said default, including, without
limitation, collection costs and reasonable attorneys' fees, to the extent
actually incurred.

         13.      REMEDIES CUMULATIVE. No remedy herein conferred upon the
holder of this Note is intended to be exclusive of any other remedy and each and
every such remedy shall be cumulative and shall be in addition to every other
remedy given hereunder or now or hereafter existing at law or in equity or by
statute or otherwise.

         14.      REMEDIES NOT WAIVED. No course of dealing between the
Corporation and the holders of this Note or any delay on the part of the holder
hereof in exercising any rights hereunder shall operate as a waiver of any right
of any holder of this Note.

         15.      CONVERSION.

         (a)      Conversion of this Note into Common Stock. All or a portion of
the principal amount of this Note shall, at any time and at the option of the
Holder, be convertible into a number of shares of Common Stock, calculated by
dividing the portion of the principal amount of such Notes to be converted
(together with any accrued and unpaid interest on such portion of the principal
amount) by $_____ (subject to equitable adjustment for stock splits, stock
dividends, recapitalizations, reorganizations or other similar events, the
"Common Stock Conversion Price" or "Conversion Price") with the proportional
value of any fractional shares resulting therefrom paid by the Corporation in
cash to the Holder upon conversion. The Holder will give the Corporation at
least 10 business days notice of its intention to convert all or a portion of
the principal amount of the Notes into Common Stock, except if such conversion
follows a notice of prepayment pursuant to Section 5(b) hereof. The Corporation
shall present and deliver certificates evidencing the proper number of shares of
Common Stock to the Holder, in such denominations and in such name or names as
the Holder may designate by notice to the



                                       11
<PAGE>

Corporation, to each Holder, at a time and place mutually agreeable to the
Holder and the Corporation, in exchange for delivery of this Note to the
Corporation. Upon receipt of this Note in exchange for such certificate or
certificates of Common Stock, the Corporation shall cancel and destroy this
Note, and this Note shall thereafter be null, void and of no effect. If any of
the principal amount of Note tendered to the Corporation pursuant to this
Section 15(a) shall remain unconverted and outstanding following the issuance of
such Common Stock, the Corporation shall execute and deliver to the Holder at
the same time and in the same manner as the certificate evidencing such Holder's
Common Stock is delivered, a replacement note that shall be identical in all
respects as this Note, except that the principal amount shall be reduced by the
principal amount of this Note converted to Common Stock. If this Note has been
issued pursuant to a Funding Request that is delivered after the automatic
conversion of a previously-issued Note pursuant to Section 1.04(b) thereof, it
shall be convertible into Purchaser Conversion Preferred (as defined below).

         (b)      Automatic Conversion of this Note into Preferred Stock.
Simultaneous with the Corporation raising an aggregate of $50,000,000 (the
"Conversion Amount") in cash through the issuance of convertible preferred stock
prior to the Maturity Date, excluding the Notes and PIK Notes, but including
shares issued upon conversion of up to $20,000,000 aggregate principal amount of
the Corporation's 10% Convertible Senior Secured Notes due February 20, 2006
issued to affiliates of Welsh, Carson, Anderson & Stowe ("Welsh Carson")
(excluding any notes issued to Welsh Carson in kind for interest on such notes),
all of the principal amount of this Note, together with any PIK Notes, Notes
then-payable in kind for accrued and unpaid interest as of such date and Notes
to be purchased on such date by the Purchaser, subject to satisfaction of all
applicable conditions set forth in Section 6.02 of the Purchase Agreement, at a
special Closing on such date with a Purchase Price equal to the difference
between $30,000,000 and the aggregate Purchase Price paid by the Purchaser
pursuant to all Closings completed pursuant to this Agreement as of such date
pursuant to the terms of the Purchase Agreement (collectively, the "Purchaser
Conversion Notes"), shall be converted into a number of shares of convertible
preferred stock ("Purchaser Conversion Preferred") having the same rights,
preferences, privileges and restrictions as shares issued (the "Recent Equity
Financing Shares") pursuant to the Corporation's most recent preferred stock
financing (the "Recent Equity Financing"), except that the initial conversion
price of such Purchaser Conversion Preferred shall be the lesser of (i) the
initial conversion price of the Recent Equity Financing Shares, (ii) the initial
conversion price of shares issued pursuant to any financing which comprises a
portion of the Conversion Amount (excluding shares issued upon conversion of the
notes previously issued to Welsh Carson referred to above), and (iii) the Common
Stock Conversion Price. The Purchaser Conversion Preferred shall be of the same
class, but separate series, as the Recent Equity Financing Shares. The
proportional value of any fractional shares resulting from the issuance of
Purchaser Conversion Preferred shall be paid by the Corporation in cash to the
Purchaser. Notwithstanding the foregoing, the following actions by the
Corporation shall not be aggregated in calculating the Conversion Amount: (i)
the issuance of any shares of Common Stock pursuant to a stock option plan
approved by the Corporation's Board of Directors, (ii) the issuance of stock,
warrants or other securities or rights to persons or entities with which the
Corporation has bona fide business relationships provided such issuances



                                       12
<PAGE>

are for other than primarily equity financing purposes, provided that in any
such case (involving the foregoing clauses (i) or (ii)) such issuance has been
approved by a majority of the members of the Corporation's Board of Directors.
The Corporation will provide the Holder with at least 10 business days notice in
advance of an expected closing of an equity financing which will result in the
raising of the Conversion Amount, noting the time and place of such event. The
Corporation shall present and deliver certificates evidencing the proper number
of Recent Equity Financing Shares to the Holder, in such denominations and in
such name or names as the Holder may designate by notice to the Corporation, to
the Holder at the closing of the Recent Equity Financing in exchange for
delivery of this Note to the Corporation. Upon receipt of this Note in exchange
for such certificate or certificates of stock evidencing the proper number of
Recent Equity Financing Shares, the Corporation shall cancel and destroy this
Note or Notes, and this Note or Notes shall thereafter be null, void and of no
effect.

         (c)      Conversion Prior to Optional Prepayment. In the event the
holder of this Note receives a notice from the Corporation in accordance with
Section 5(b) that the Corporation intends to optionally prepay the Note, the
holder of this Note shall have the option, prior to the consummation of such
prepayment, to convert all or portion of the unpaid principal amount of this
Note together with a corresponding portion of the accrued interest hereon into
shares of Common Stock in accordance with the terms of paragraph (a) above. The
holder shall exercise such right of conversion by giving written notice to the
Corporation in accordance with paragraph (a) above prior to the date of such
prepayment referred to in the Corporation's notice to the holder in accordance
with Section 6.

         (d)      Issuance of Certificates; Time Conversion Effected. Promptly
after (i) the receipt of the written notice referred to in paragraph (a) above
or (ii) the occurrence of the events described in paragraph (b) above, as the
case may be, and surrender of this Note, the Corporation shall issue and
deliver, or cause to be issued and delivered, to the holder, registered in such
name or names as such holder may direct, a certificate or certificates for the
number of whole shares of Common Stock or preferred stock, as the case may be,
issuable upon the conversion of such unpaid principal amount of this Note
together with interest and any Applicable Premium Amount. To the extent
permitted by law, such conversion shall be deemed to have been effected as of
the close of business on the date on which this Note shall have been surrendered
as aforesaid, and at such time the rights of the holder of this Note, to the
extent of the principal amount thereof and any other amounts to be converted,
shall cease, and the person or persons in whose name or names any certificate or
certificates for shares of Common Stock, or preferred stock, as the case may be,
shall be issuable upon such conversion shall be deemed to have become the holder
or holders of record of the shares represented thereby.

         (e)      Fractional Shares; Dividends; Partial Conversion. No
fractional shares shall be issued upon conversion of the principal amount of
this Note or any portion thereof, and no payment or adjustment shall be made
upon any conversion on account of any cash dividends on the Common Stock issued
upon such conversion. In case of the conversion of only a portion of the unpaid
principal amount of this Note, the holder hereof, at its option, may require the
Corporation to execute and deliver at the expense of the Corporation (other than
for transfer



                                       13
<PAGE>

taxes, if any), upon surrender of this Note, a new Note registered in the name
of such person or persons as may be designated by such holder for the principal
amount of this Note then remaining unpaid, dated as of the date to which
interest has been paid on the principal amount of this Note then remaining
unpaid, or may present this Note to the Corporation for notation hereon of the
payment of the portion of the principal amount of this Note so converted. If any
fractional interest in a share of Common Stock or preferred stock, as the case
may be, would, except for the provisions of the first sentence of this paragraph
(e), be deliverable upon any such conversion, the Corporation, in lieu of
delivering the fractional share thereof, shall pay to the holder surrendering
this Note for conversion an amount in cash equal to such fractional interest
multiplied by the Conversion Price then in effect.

         (f)      Adjustment of Conversion Price upon Issuance of Common Shares.
If and whenever the Corporation shall issue or sell, or is in accordance with
subparagraphs (i) through (vii) deemed to have issued or sold, any shares of its
Common Stock for a consideration per share less than the Conversion Price in
effect immediately prior to the time of such issue or sale, then, forthwith upon
such issue or sale, the Conversion Price shall be reduced to the price
(calculated to the nearest cent) determined by dividing (x) an amount equal to
the sum of (1) the number of shares of Common Stock outstanding immediately
prior to such issue or sale (including as outstanding all shares of Common Stock
issuable upon conversion of outstanding Notes) multiplied by the then existing
Conversion Price, and (2) the consideration, if any, received by the Corporation
upon such issue or sale, by (y) the total number of shares of Common Stock
outstanding immediately after such issue or sale (including as outstanding all
shares of Common Stock issuable upon conversion of outstanding Notes).

         No adjustment of the Conversion Price, however, shall be made in an
amount less than $.01 per share, and any such lesser adjustment shall be carried
forward and shall be made at the time and together with the next subsequent
adjustment which together with any adjustments so carried forward shall amount
to $.01 per share or more.

         For purposes of this subparagraph (f), the following subparagraphs (i)
to (vii) shall also be applicable:

          (i) Issuance of Rights or Options. In case at any time the Corporation
     shall in any manner grant (whether directly or by assumption in a merger or
     otherwise) any rights to subscribe for or to purchase, or any options for
     the purchase of, Common Stock or any stock or securities convertible into
     or exchangeable for Common Stock (such rights or options being herein
     called "Options" and such convertible or exchangeable stock or securities
     being herein called "Convertible Securities") whether or not such Options,
     or the right to convert or exchange any such Convertible Securities are
     immediately exercisable, and the price per share for which Common Stock is
     issuable upon the exercise of such Options or upon conversion or exchange
     of such Convertible Securities (determined by dividing (x) the total
     amount, if any, received or receivable by the Corporation as consideration
     for the granting of such Options, plus the minimum aggregate amount of
     additional consideration payable to the Corporation upon the



                                       14
<PAGE>

     exercise of all such Options, plus, in the case of such Options which
     relate to Convertible Securities, the minimum aggregate amount of
     additional consideration, if any, payable upon the issue or sale of such
     Convertible Securities and upon the conversion or exchange thereof, by (y)
     the total maximum number of shares of Common Stock issuable upon the
     exercise of such Options or upon the conversion or exchange of all such
     Convertible Securities issuable upon the exercise of such Options) shall be
     less than the Conversion Price in effect immediately prior to the time of
     the granting of such Options, then the total maximum number of shares of
     Common Stock issuable upon the exercise of such Options or upon conversion
     or exchange of the total maximum amount of such Convertible Securities
     issuable upon the exercise of such Options shall be deemed to have been
     issued for such price per share as of the date of granting of such Options
     and thereafter shall be deemed to be outstanding. Except as otherwise
     provided in subparagraph (iii), no adjustment of the Conversion Price shall
     be made upon the actual issue of such Common Stock or of such Convertible
     Securities upon exercise of such Options or upon the actual issue of such
     Common Stock upon conversion or exchange of such Convertible Securities. If
     at the end of the period during which such Options or Convertible
     Securities are exercisable not all Options or Convertible Securities shall
     have been exercised or converted, the adjusted Conversion Price shall be
     immediately readjusted to what it would have been based upon the number of
     additional shares of Common Stock actually issued in respect of such
     Options and Convertible Securities.

          (ii) Issuance of Convertible Securities. In case the Corporation shall
     in any manner issue (whether directly or by assumption in a merger or
     otherwise) or sell any Convertible Securities, whether or not the rights to
     exchange or convert thereunder are immediately exercisable, and the price
     per share for which Common Stock is issuable upon such conversion or
     exchange (determined by dividing (x) the total amount received or
     receivable by the Corporation as consideration for the issue or sale of
     such Convertible Securities, plus the minimum aggregate amount of
     additional consideration, if any, payable to the Corporation upon the
     conversion or exchange thereof, by (y) the total maximum number of shares
     of Common Stock issuable upon the conversion or exchange of all such
     Convertible Securities) shall be less than the Conversion Price in effect
     immediately prior to the time of such issue or sale, then the total maximum
     number of shares of Common Stock issuable upon conversion or exchange of
     all such Convertible Securities shall be deemed to have been issued for
     such price per share as of the date of the issue or sale of such
     Convertible Securities and thereafter shall be deemed to be outstanding,
     provided that (1) except as otherwise provided in subparagraph (iii) below,
     no adjustment of the Conversion Price shall be made upon the actual issue
     of such Common Stock upon conversion or exchange of such Convertible
     Securities and (2) if any such issue or sale of such Convertible Securities
     is made upon exercise of any Option to purchase any such Convertible
     Securities for which adjustments of the Conversion Price have been or are
     to be made pursuant to other provisions of this paragraph (f), no further
     adjustment of the Conversion Price shall be made by reason of such issue or
     sale. If at the end of the period during which such Convertible Securities
     are convertible not all Convertible Securities shall have been converted,
     the adjusted Conversion Price shall be



                                       15
<PAGE>

     immediately readjusted to what it would have been based upon the number of
     additional shares of Common Stock actually issued in respect of such
     Convertible Securities.

          (iii) Change in Option Price or Conversion Rate. Upon the happening of
     any of the following events, namely, if the purchase price provided for in
     any Option referred to in subparagraph (i), the additional consideration,
     if any, payable upon the conversion or exchange of any Convertible
     Securities referred to in subparagraph (i) or (ii), or the rate at which
     any Convertible Securities referred to in subparagraph (i) or (ii) are
     convertible into or exchangeable for Common Stock shall change at any time
     (other than under or by reason of provisions designed to protect against
     dilution), the Conversion Price in effect at the time of such event shall
     forthwith be readjusted to the Conversion Price which would have been in
     effect at such time had such Options or Convertible Securities still
     outstanding provided for such changed purchase price, additional
     consideration or conversion rate, as the case may be, at the time initially
     granted, issued or sold; and on the expiration of any such Option or
     termination of any such right to convert or exchange such Convertible
     Securities, the Conversion Price then in effect hereunder shall forthwith
     be increased to the Conversion Price which would have been in effect at the
     time of such expiration or termination had such Option or Convertible
     Securities, to the extent outstanding immediately prior to such expiration
     or termination, never been issued, and the Common Stock issuable thereunder
     shall no longer be deemed to be outstanding. If the purchase price provided
     for in any such Option referred to in subparagraph (i) or the rate at which
     any Convertible Securities referred to in subparagraph (i) or (ii) are
     convertible into or exchangeable for Common Stock shall be reduced at any
     time under or by reason of provisions with respect thereto designed to
     protect against dilution, then, in case of the delivery of Common Stock
     upon the exercise of any such Option or upon conversion or exchange of any
     such Convertible Securities, the Conversion Price then in effect hereunder
     shall forthwith be adjusted to such respective amount as would have been
     obtained had such Option or Convertible Securities never been issued as to
     such Common Stock and had adjustments been made upon the issuance of the
     shares of Common Stock delivered as aforesaid, but only if as a result of
     such adjustment the Conversion Price then in effect hereunder is thereby
     reduced.

          (iv) Stock Dividends. Without duplication of the adjustment
     contemplated by clause (g) below, in case the Corporation shall declare a
     dividend or make any other distribution upon any stock of the Corporation
     payable in Common Stock, Options or Convertible Securities, any Common
     Stock, Options or Convertible Securities, as the case may be, issuable in
     payment of such dividend or distribution shall be deemed to have been
     issued or sold without consideration.

          (v) Consideration for Stock. In case any shares of Common Stock,
     Options or Convertible Securities shall be issued or sold for cash, the
     consideration received therefore shall be deemed to be the amount received
     by the Corporation therefore, without deduction therefrom of any expenses
     incurred or any underwriting commissions or concessions paid or allowed by
     the Corporation in connection therewith. In case any



                                       16
<PAGE>

     shares of Common Stock, Options or Convertible Securities shall be issued
     or sold for a consideration other than cash, the amount of the
     consideration other than cash received by the Corporation shall be deemed
     to be the fair value of such consideration as determined in good faith by
     the Board of Directors of the Corporation, without deduction of any
     expenses incurred or any underwriting commissions or concessions paid or
     allowed by the Corporation in connection therewith. In case any Options
     shall be issued in connection with the issue and sale of other securities
     of the Corporation, together compromising one integral transaction in which
     no specific consideration is allocated to such Options by the parties
     thereto, such Options shall be deemed to have been issued without
     consideration.

          (vi) Record Date. In case the Corporation shall take a record of the
     holders of its Common Stock for the purpose of entitling them (x) to
     receive a dividend or other distribution payable in Common Stock, Options
     or Convertible Securities, or (y) to subscribe for or purchase Common
     Stock, Options or Convertible Securities, then such record date shall be
     deemed to be the date of the issue or sale of the shares of Common Stock
     deemed to have been issued or sold upon the declaration of such dividend or
     the making of such other distribution or the date of the granting of such
     right of subscription or purchase, as the case may be.

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

Notwithstanding anything to the contrary contained in this paragraph (f),
paragraph (f) is subject to the prior approval of the Corporation's
shareholders, which the Corporation shall seek to obtain as promptly as
practicable, if such shareholder approval would be required under the
Marketplace Rules of the Nasdaq National Market (the "NASDAQ") if paragraph (f)
were to otherwise operate in accordance with its terms, unless the NASDAQ has
waived such requirement.

         (g)      Subdivision or Combination of Stock. In case the Corporation
shall at any time declare a dividend or make any other distribution upon any
stock of the Corporation payable in Common Stock or subdivide its outstanding
shares of Common Stock into a greater number of shares, the Conversion Price in
effect immediately prior to such subdivision shall be proportionately reduced,
and conversely, in case the outstanding shares of Common Stock of the
Corporation shall be combined into a smaller number of shares, the Conversion
Price in effect immediately prior to such combination shall be proportionately
increased.

         (h)      Certain Issues of Stock Excepted. Anything herein to the
contrary notwithstanding, the Corporation shall not make any adjustment of the
Conversion Price in the case of (i) the issuance of shares of Common Stock upon
conversion of Notes; (ii) the issuance of Options or shares of Common Stock to
employees, directors or consultants of the Corporation



                                       17
<PAGE>

or its subsidiaries, either directly or pursuant to Options, pursuant to plans
or arrangements approved by the Board of Directors (or Compensation Committee
thereof) of the Corporation; (iii) the issuance of shares of Common Stock in
respect of any Convertible Securities or Options issued by the Corporation prior
to the date of this Note; or (iv) the issuance of shares of Common Stock in
connection with any acquisition, merger, consolidation, or other business
combination transaction.

         (i)      Reorganization or Reclassification. If any capital
reorganization or reclassification of the capital stock of the Corporation shall
be effected in such a way that holders of Common Stock shall be entitled to
receive stock, securities or assets with respect to or in exchange for Common
Stock, then, as a condition of such reorganization or reclassification, lawful
and adequate provisions shall be made whereby each holder of a Note shall
thereafter have the right to receive, upon the basis and upon the terms and
conditions specified herein and in lieu of the shares of Common Stock of the
Corporation immediately theretofore receivable upon the conversion of such
shares of stock, securities or assets as may be issued or payable with respect
to or in exchange for a number of outstanding shares of such Common Stock equal
to the number of shares of such stock immediately theretofore so receivable had
such reorganization or reclassification not taken place, and in any such case
appropriate provision shall be made with respect to the rights and interests of
such holder to the end that the provisions hereof (including without limitation
provisions for adjustments of the Conversion Price) shall thereafter be
applicable, as nearly as may be, in relation to any shares of stock, securities
or assets thereafter deliverable upon the exercise of such conversion rights
(including an immediate adjustment, by reason of such reorganization or
reclassification, of the Conversion Price to the value for the Common Stock
reflected by the terms of such reorganization or reclassification if the value
so reflected is less than the Conversion Price in effect immediately prior to
such reorganization or reclassification). In the event of a merger or
consolidation of the Corporation as a result of which a greater or lesser number
of shares of Common Stock of the surviving corporation are issuable to holders
of Common Stock of the Corporation outstanding immediately prior to such merger
or consolidation, the Conversion Price in effect immediately prior to such
merger or consolidation shall be adjusted in the same manner as though there
were a subdivision or combination of the outstanding shares of Common Stock of
the Corporation. The Corporation will not effect any such consolidation, merger,
or any sale of all or substantially all of its assets or properties, unless
prior to the consummation thereof the successor corporation or other entity (if
other than the Corporation) resulting from such consolidation or merger or the
corporation purchasing such assets shall assume, by written instrument executed
and mailed or delivered to each holder of Notes at the last address of such
holder appearing on the books of the Corporation, the obligation to deliver to
such holder such shares of stock, securities or assets as, in accordance with
the foregoing provisions, such holder may be entitled to receive.

         (j)      Notice of Adjustment. Upon any adjustment of the Conversion
Price, then and in each such case the Corporation shall give written notice
thereof, by first class mail, postage prepaid, addressed to each holder of Notes
at the address of such holder as set forth in the register maintained by the
Corporation for the registration of transfer and exchange of Notes,



                                       18
<PAGE>

which notice shall state the Conversion Price resulting from such adjustment,
setting forth in reasonable detail the method of calculation and the facts upon
which such calculation is based.

         (k)      Other Notices. In case at any time:

         (i) the Corporation shall declare any dividend upon its Common Stock
     payable in cash or stock or make any other distribution to the holders of
     its Common Stock;

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

         (iii) there shall be any capital reorganization or reclassification of
     the capital stock of the Corporation, or a consolidation or merger of the
     Corporation with, or a sale of all or substantially all its assets to,
     another corporation or other entity; or

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

then, in any one or more of said cases, the Corporation shall give, by first
class mail, postage prepaid, addressed to each holder of Notes at the address of
such holder as set forth in the register maintained by the Corporation for the
registration of transfer and exchange of Notes, (A) at least 20 days' prior
written notice of the date on which the books of the Corporation shall close or
a record shall be taken for such dividend, distribution or subscription rights
or for determining rights 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, at least 20
days' prior written notice of the date when the same shall take place. Such
notice in accordance with the foregoing clause (A) shall also specify, in the
case of any such dividend, distribution or subscription rights, the date on
which the holders of Common Stock shall be entitled thereto, and such notice in
accordance with the foregoing clause (B) shall also specify the date on which
the holders of Common Stock shall be entitled to exchange their Common Stock for
securities or other property deliverable upon such reorganization,
reclassification, consolidation, merger, sale, dissolution, liquidation or
winding up, as the case may be.

         (l)      Stock to Be Reserved. The Corporation will at all times
reserve and keep available out of its authorized Common Stock or its treasury
shares, solely for the purpose of issue upon the conversion of the Notes as
herein provided, such number of shares of Common Stock as shall then be issuable
upon the conversion of the unpaid principal amount of all outstanding Notes. The
Corporation covenants that all shares of Common Stock which shall be so issued
shall be duly and validly issued and fully paid and nonassessable and free from
all taxes, liens and charges with respect to the issue thereof, and, without
limiting the generality of the foregoing, the Corporation covenants that it will
from time to time take all such action within its control as may be requisite to
assure that the par value per share of the Common Stock is at all times equal to
or less than the effective Conversion Price. The Corporation will take all such


                                       19
<PAGE>

action as may be necessary to assure that all such shares of Common Stock may be
so issued without violation of any applicable law or regulation, or of any
requirements of any national securities exchange upon which the Common Stock of
the Corporation may be listed. The Corporation will not take any action which
results in any adjustment of the Conversion Price if the total number of shares
of Common Stock issued and issuable after such action upon conversion of the
Notes would exceed the total number of shares of Common Stock then authorized by
the Corporation's Certificate of Incorporation.

         (m)      Issue Tax. The issuance of certificates for shares of Common
Stock upon conversion of the Notes shall be made without charge to the holders
thereof for any issuance tax in respect thereof, provided that the Corporation
shall not be required to pay any tax which may be payable in respect of any
transfer involved in the issuance and delivery of any certificate in a name
other than that of the holder of the Note the principal amount of which is being
converted.

         (n)      Closing of Books. The Corporation will at no time close its
transfer books against the transfer of any Note or of any shares of Common Stock
issued or issuable upon the conversion of any Note in any manner which
interferes with the timely conversion of such Note.

         (o)      Definition of Common Stock. As used in this Section 15, the
term "Common Stock" shall mean and include the Corporation's authorized Common
Stock, $.01 par value, as constituted on the date hereof, and shall also include
any capital stock of any class of the Corporation thereafter authorized which
shall not be limited to a fixed sum or percentage of par value in respect of the
rights of the holders thereof to participate in dividends or in the distribution
of assets upon the voluntary or involuntary liquidation, dissolution or winding
up of the Corporation.

         16.      COVENANTS BIND SUCCESSORS AND ASSIGNS. All the covenants,
stipulations, promises and agreements in this Note contained by or on behalf of
the Corporation shall bind its successors and assigns, whether so expressed or
not.

         17.      GOVERNING LAW. This Note shall be governed and construed in
accordance with the laws of the State of New York, without giving effect to the
conflict of laws principles thereof.

         18.      HEADINGS. The headings of the Sections and subsections of this
Note are inserted for convenience only and do not constitute a part of this
Note.

         19.      NOTICES. Any notice or other communications required or
permitted hereunder shall be deemed to be sufficient if contained in a written
instrument delivered in person or duly sent by first class certified mail,
postage prepaid, by nationally recognized overnight courier, or by facsimile
