                        SAVVIS COMMUNICATIONS CORPORATION

                           CERTIFICATE OF DESIGNATIONS

                                       FOR

                      SERIES A CONVERTIBLE PREFERRED STOCK

         SAVVIS COMMUNICATIONS CORPORATION, a corporation organized and existing
under the General Corporation Law of the State of Delaware (the "ISSUER"), does
hereby certify that (i) pursuant to authority conferred upon the Board of
Directors of the Issuer by its Certificate of Incorporation, as amended to date,
and pursuant to the provisions of Section 151 of the General Corporation Law of
the State of Delaware, the Board of Directors authorized the creation and
issuance of the Issuer's Series A Convertible Preferred Stock (referred to
herein as the "PREFERRED STOCK"), and (ii) the following resolution, which was
duly adopted by the Board of Directors on February 26, 2002, remains in full
force and effect. Certain capitalized terms used herein are defined in Section
12.

     RESOLVED, that pursuant to the authority expressly granted to and vested in
     the Board of Directors of the Issuer by the provisions of the Certificate
     of Incorporation, as amended from time to time (the "CERTIFICATE OF
     INCORPORATION"), and pursuant to Section 151(g) of the General Corporation
     Law of the State of Delaware, there be created from the 50,000,000 shares
     of preferred stock, $0.01 par value, of the Issuer authorized to be issued
     pursuant to the Certificate of Incorporation, a series of preferred stock,
     having the number of shares and, to the extent that the designations,
     powers, preferences and relative and other special rights and the
     qualifications, limitations and restrictions of such Preferred Stock are
     not stated and expressed in the Certificate of Incorporation, the powers,
     preferences and relative and other special rights and the qualifications,
     limitations and restrictions, as follows:

1.   Designation and Number of Shares.
     --------------------------------

         The series will be designated as the "Series A Convertible Preferred
Stock" and the number of shares constituting such series will be 210,000 shares.

2.   Dividends.
     ---------

     2.1 Payment of Dividends.
         --------------------

         (a) The Holders of Preferred Stock shall be entitled to participating
cumulative dividends, in preference to dividends on any Junior Securities, which
shall accrue as provided herein, and shall be paid when, as and if declared by
the Board of Directors. Dividends on each share of Preferred Stock will accrue
on a daily basis at the Dividend Accretion Rate on the Accreted Value of such
share from and including, the applicable Issuance Date to the first to occur of
(i) the date on which such share is redeemed in accordance with Section 5, (ii)
the date on which such share is converted in accordance with Section 4, (iii)
the date such share is purchased in accordance with Section 9 or 10, or (iv) the
date the Issuer is liquidated, dissolved or wound up in accordance with Section
6. Dividends shall accrue as provided herein whether or

<PAGE>

not such dividends (or a portion thereof) have been declared and whether or not
there are any unrestricted funds of the Issuer legally available for the payment
of dividends. Accrued but unpaid dividends shall accrete quarterly by being
added to the Accreted Value on each Dividend Accretion Date. For purposes of
determining the amount of dividends "accrued" (i) as of or before the first
Dividend Accretion Date and as of any date that is not a Dividend Accretion
Date, such amount shall be calculated on the basis of the applicable Dividend
Accretion Rate for the actual number of days elapsed from and including, the
applicable Issuance Date (in case of the first Dividend Accretion Date and any
date prior to the first Dividend Accretion Date) or the last preceding Dividend
Accretion Date (in case of any other date) to the date as of which such
determination is to be made, and (ii) as of any Dividend Accretion Date after
the first Dividend Accretion Date, such amount shall be calculated on the basis
of such rate per annum based on a 360-day year of twelve 30-day months.

         (b) After March 18, 2010 the Company may, at its option, pay in cash
dividends on Preferred Stock that would accrue after such date.

         (c) In the event the Board of Directors of the Issuer shall declare a
cash dividend payable with respect to the then outstanding shares of Common
Stock in any particular quarter, which exceeds, on a per share basis, the amount
of the dividend accreted per share of Preferred Stock in such quarter divided by
the number of shares of Common Stock such share of Preferred Stock is then
convertible into (the "PER SHARE PREFERRED DIVIDEND AMOUNT"), then the Holders
of the Preferred Stock shall be entitled to, prior to the payment of any such
dividend declared with respect to the outstanding shares of Common Stock (the
"PER SHARE COMMON DIVIDEND AMOUNT"), (i) the accretion of dividends for such
quarter pursuant to Section 2.1(a) and (ii) the excess, in cash, of the Per
Share Common Dividend Amount over the Per Share Preferred Dividend Amount
multiplied by the number of shares of Common Stock into which the Preferred
Stock is then convertible. The Holders of Preferred Stock will not be required
to convert the shares of Preferred Stock held by such Holders as a condition to
receiving the cash dividend contemplated by this Section 2.1(c).

     2.2 Declaration of Dividends.
         ------------------------

         (a) Except as permitted under Section 7.2(c), (i) no dividends or other
distributions may be declared, made or paid upon, or any funds set apart for the
payment of dividends upon, any of the Junior Securities or Parity Securities by
the Issuer or any of its Subsidiaries, and (ii) no Junior Securities or Parity
Securities, may be purchased, redeemed or otherwise acquired or retired for
value for any consideration (and no money may be paid into or set apart or made
available for a sinking or other like fund for the purchase, redemption or other
acquisition or retirement for value of any shares of any such stock) by the
Issuer or any of its Subsidiaries. Notwithstanding anything to the contrary
contained herein, the provisions of this Section 2.2(a) will be of no further
force and effect upon the earlier of the date on which (A) less than twenty
percent (20%) of the aggregate of the number of shares of Preferred Stock issued
on all Issuance Dates remains outstanding or (B) less than forty percent (40%)
of the aggregate of the number of shares of Preferred Stock issued on all
Issuance Dates remains outstanding and such outstanding Preferred Stock
constitutes less than twenty percent (20%) of the total outstanding voting power
of the Issuer.

         (b) If at any time the Issuer shall pay dividends in accordance with
Section 2.1(b) with respect to the Preferred Stock in an amount that is less
than the total amount of the Accrued Dividends, such dividends shall be
distributed ratably among the Holders based upon the aggregate Accrued Dividends
on the Preferred Stock held by each Holder.

                                       2

3.  Ranking.
    -------

    3.1 The Preferred Stock will, with respect to dividend distributions and
distributions upon a Liquidation Event, rank: (a) senior to all classes of
Junior Securities; (b) on a parity with Parity Securities; and (c) subject to
Section 7.2(b), junior to each class of Senior Securities.

    3.2 Subject to applicable law and the terms of Section 7 of this Certificate
of Designations, the Issuer is entitled to amend its Certificate of
Incorporation to authorize one or more additional series of preferred stock,
file certificates of designation, and issue without restriction from time to
time, any series of Junior Securities, Parity Securities, or Senior Securities.

4.  Conversion.
    -----------

    4.1  Conversion Rights.
         -----------------

         (a) Each Holder of Preferred Stock shall have the right, at its option,
at any time and from time to time after the Effective Date to convert, subject
to the terms and provisions of this Section 4, any or all of such Holder's
shares of Preferred Stock into Conversion Shares.

             (i) The conversion right of a Holder of Preferred Stock under this
         Section 4.1(a) shall be exercised by the Holder by the surrender of the
         certificate representing shares to be converted to the Issuer
         accompanied by a Conversion Notice.

             (ii) If the conversion under this Section 4.1(a) is in connection
         with an underwritten offering of securities registered pursuant to the
         Securities Act, the conversion may, at the option of any Holder
         tendering Preferred Stock for conversion, be conditioned upon the
         closing with the underwriter of the sale of securities pursuant to such
         offering, in which event the person(s) entitled to receive the Common
         Stock issuable upon such conversion of the Preferred Stock shall not be
         deemed to have converted such Preferred Stock until immediately prior
         to the closing of the sale of such securities.

         (b) Immediately prior to the close of business on any Conversion Date,
each Holder of Preferred Stock whose shares of Preferred Stock have been
converted in whole or in part pursuant to this Section 4.1 shall be deemed to be
the Holder of record of Common Stock issuable upon such conversion of such
Holder's Preferred Stock notwithstanding that the share register of the Issuer
shall then be closed or that certificates representing such Common Stock shall
not then be actually delivered to such Person.

         (c) On any Conversion Date, all rights with respect to the shares of
Preferred Stock so converted, including the rights, if any, to receive notices,
will terminate, except the rights of Holders thereof to: (i) receive
certificates for the number of shares of Common Stock into which such shares of
Preferred Stock have been converted; and (ii) exercise the rights to which they
are entitled as Holders of Common Stock.

         (d) If any Conversion Date shall not be a Business Day, then the
applicable conversion right shall be deemed exercised on the next Business Day.

                                       3

<PAGE>

         The conversion rights under Section 4.1(a) shall terminate with respect
to any share of Preferred Stock at the close of business on the Business Day
prior to the date of redemption or repurchase (permitted under this Certificate
of Designations) for such share of Preferred Stock unless the Issuer shall
default in making the payment due upon redemption or repurchase thereof.

     4.2 The Conversion Price shall be subject to adjustment, without
duplication, from time to time as follows:

         (a) Stock Splits and Combinations. In case the Issuer shall at any time
or from time to time after the Original Issuance Date (i) subdivide or split the
outstanding shares of Common Stock, (ii) combine or reclassify the outstanding
shares of Common Stock into a smaller number of shares or (iii) issue by
reclassification of the shares of Common Stock any shares of capital stock of
the Issuer, then, and in each such case, the Conversion Price in effect
immediately prior to such event or the record date therefor, whichever is
applicable, shall be adjusted so that the Holder of any shares of Preferred
Stock thereafter surrendered for conversion shall be entitled to receive the
number of shares of Common Stock or other securities of the Issuer which such
Holder would have owned or have been entitled to receive after the occurrence of
any of the events described above, had such shares of Preferred Stock been
surrendered for conversion immediately prior to the occurrence of such event or
the record date therefor, whichever is applicable. An adjustment made pursuant
to this subparagraph (a) shall become effective at the close of business on the
day upon which such corporate action becomes effective. Such adjustment shall be
made successively whenever any event listed above shall occur.

         (b) Dividends and Distributions in Common Stock. In case the Issuer
shall at any time or from time to time after the Original Issuance Date pay a
dividend or make a distribution payable in shares of Common Stock on any class
of Capital Stock of the Issuer other than dividends or distributions of shares
of Common Stock or other securities with respect to which adjustments are
provided in paragraph (a) above, the Conversion Price shall be adjusted so that
the Holder of each share of Preferred Stock shall be entitled to receive upon
conversion thereof the number of shares of Common Stock determined by
multiplying (1) the applicable Conversion Price by (2) a fraction, the numerator
of which shall be the number of shares of Common Stock theretofore outstanding
and the denominator of which shall be the sum of such number of shares and the
total number of shares issuable in such dividend or distribution. The provisions
of this clause shall similarly apply to successive distributions.

         (c) Distribution of Indebtedness, Securities or Assets. In case the
Issuer shall at any time or from time to time after the Original Issuance Date
distribute to any Holders of Common Stock (whether by dividend or in a merger,
amalgamation, consolidation or otherwise) evidences of indebtedness, shares of
Capital Stock of any class or series, other securities or assets (other than
securities referred to in subparagraph (d) below or a dividend payable
exclusively in cash and other than as a result of a Fundamental Change) in
respect of such Holder's Common Stock, the Conversion Price in effect
immediately prior to the close of business on the record date fixed for
determination of stockholders entitled to receive such distribution shall be
reduced by multiplying such Conversion Price by a fraction, the numerator of
which is the Volume Weighted Market Value on such record date less the fair
market value (as determined by the Board of Directors of the Issuer, whose
determination in good faith shall be conclusive) of the portion of such
evidences of indebtedness, shares of Capital Stock, other securities, cash and
assets so distributed applicable to one share of Common Stock and the
denominator of which is the Volume Weighted Market Value. Such adjustment shall
be made successively whenever any such event shall occur.

                                       4

<PAGE>

         (d) Sales of Securities Below Conversion Price. Subject to the last
sentence of this Section 4.2(d), if the Issuer shall issue any Additional Stock
(as defined below) without consideration or for a consideration per share less
than the Conversion Price in effect immediately prior to the issuance of such
Additional Stock, then the Conversion Price in effect immediately prior to each
such issuance shall automatically be adjusted as set forth in this Section
4.2(d). Such adjustment shall be made successively whenever such event shall
occur.

              (i) Whenever the Conversion Price is adjusted pursuant to this
         Section 4.2(d), the new Conversion Price shall be determined by
         multiplying the Conversion Price then in effect by a fraction, (x) the
         numerator of which shall be the number of shares of Common Stock
         outstanding immediately prior to such issuance (the "OUTSTANDING
         COMMON") plus the number of shares of Common Stock that the aggregate
         consideration (determined in the manner provided in Section 4(d)(iii))
         received by the Issuer for such issuance would purchase at the
         Conversion Price in effect immediately prior to such issuance; and (y)
         the denominator of which shall be the number of shares of Outstanding
         Common plus the number of shares of such Additional Stock. For purposes
         of the foregoing calculation, the term "Outstanding Common" shall
         include, without limitation, shares of Common Stock issued or issuable
         upon the exercise, exchange or conversion of outstanding securities,
         excluding Common Stock issuable upon the exercise, exchange or
         conversion of options, warrants or similar rights to acquire Common
         Stock, at a price greater than the Volume Weighted Market Value as of
         the date of adjustment.

              (ii) For purposes of this Section 4.2(d), "ADDITIONAL STOCK" shall
         mean any shares of Common Stock issued (or deemed to have been issued
         pursuant to Section 4.2(d)(iv)) by the Issuer other than: (1) Common
         Stock issued pursuant to a transaction described in Section 4.2(a) or
         4.2(b), (2) shares of Common Stock issued or issuable upon conversion
         of the Preferred Stock, (3) in addition to the shares of Common Stock
         described in 4.2(d)(ii)(4) below, shares of Common Stock or options,
         warrants or similar rights to purchase shares of Common Stock, which
         shares are issuable or issued to employees, consultants or directors of
         the Issuer directly or pursuant to a stock option, restricted stock,
         employee stock purchase or similar plan approved by the Board of
         Directors of the Issuer and (4) shares of Common Stock issued or
         issuable upon conversion of all securities convertible, exchangeable or
         exercisable for, or rights to purchase, shares of Common Stock validly
         issued and outstanding as of the Original Issuance Date, including
         pursuant to warrants issued to creditors of the Issuer on such date.

              (iii) In the case of the issuance of Common Stock for cash, the
         consideration shall be deemed to be the amount of cash paid therefor
         before deducting any reasonable discounts, commissions or other
         expenses allowed, paid or incurred by the Issuer for any underwriting
         or otherwise in connection with the issuance and sale thereof. In the
         case of the issuance of the Common Stock for a consideration in whole
         or in part other than cash, the consideration other than cash shall be
         deemed to be the fair value thereof as determined by the Board of
         Directors of the Issuer irrespective of any accounting treatment.

                                       5

<PAGE>

              (iv) In the case of the issuance of options to purchase or rights
         to subscribe for Common Stock, securities by their terms or by
         agreement with the Issuer convertible into or exchangeable for Common
         Stock or options to purchase or rights to subscribe for such
         convertible or exchangeable securities, the following provisions shall
         apply for all purposes of this Section 4.2(d):

                     (1) The aggregate maximum number of shares of Common Stock
              deliverable upon exercise (assuming the satisfaction of any
              conditions to exercisability, including without limitation, the
              passage of time, but without taking into account potential
              antidilution adjustments) of such options to purchase or rights to
              subscribe for Common Stock shall be deemed to have been issued at
              the time such options or rights were issued and for a
              consideration equal to the consideration (determined in the manner
              provided in Section 4.2(d)(iii)), if any, received by the Issuer
              upon the issuance of such options or rights plus the minimum
              exercise price provided in such options or rights (without taking
              into account potential antidilution adjustments) for the Common
              Stock covered thereby.

                     (2) The aggregate maximum number of shares of Common Stock
              deliverable upon conversion of or in exchange (assuming the
              satisfaction of any conditions to convertibility or
              exchangeability, including, without limitation, the passage of
              time, but without taking into account potential antidilution
              adjustments, accrual of dividends or payment of any premiums or
              preferences conditioned upon the occurrence of specified
              transactions) for any such convertible or exchangeable securities
              or upon the exercise of options to purchase or rights to subscribe
              for such convertible or exchangeable securities and subsequent
              conversion or exchange thereof shall be deemed to have been issued
              at the time such securities were issued or such options or rights
              were issued and for a consideration equal to the consideration, if
              any, received by the Issuer for any such securities and related
              options or rights (excluding any cash received on account of
              accrued interest or accrued dividends), plus the minimum
              additional consideration, if any, to be received by the Issuer
              (without taking into account potential antidilution adjustments)
              upon the conversion or exchange of such securities or the exercise
              of any related options or rights (the consideration in each case
              to be determined in the manner provided in Section 4.2(d)(iii)).

              (v) Notwithstanding any other provisions of this Section 4.2(d),
         no adjustment of the Conversion Price pursuant to this Section 4.2(d)
         shall have the effect of increasing the Conversion Price above the
         Conversion Price in effect immediately prior to such adjustment.

         Notwithstanding anything herein to the contrary, this Section 4.2(d)
will be effective only on and after the Effective Date, whether or not the
Issuer is subject to the Marketplace Rules of The Nasdaq Stock Market, Inc.

         (e) Fundamental Changes. In case of any Fundamental Change, the Holder
of each share of Preferred Stock outstanding immediately prior to the occurrence
of such Fundamental Change shall have the right upon any subsequent conversion
to receive the kind and amount of stock, other securities, cash and assets that
such Holder would have received if

                                       6

<PAGE>

such share had been converted immediately prior thereto. In any such case,
appropriate adjustment shall be made in the application of the provisions of
this Section 4 with respect to the rights of the Holders of Preferred Stock
after the Fundamental Change to the end that the provisions of this Section 4
shall be applicable after that event in a manner as nearly equivalent as
practicable as before the Fundamental Change.

         (f) Limitation on Adjustments. Anything in the above subparagraphs (a)
through (e) to the contrary notwithstanding, the Issuer shall not be required to
give effect to any adjustment in the Conversion Price unless and until the net
effect of one or more adjustments (each of which shall be carried forward until
counted toward adjustment), determined as above provided, shall have resulted in
a change of the Conversion Price by at least 1%, and when the cumulative net
effect of more than one adjustment so determined shall be to change the
Conversion Price by at least 1%, such change in the Conversion Price shall
thereupon be given effect. In the event that, at any time as a result of the
provisions of this Section, the Holder of shares of Preferred Stock upon
subsequent conversion shall become entitled to receive any shares of Capital
Stock of the Issuer other than Common Stock, the number of such other shares so
receivable upon conversion of shares of Preferred Stock shall thereafter be
subject to adjustment from time to time in a manner and on terms as nearly
equivalent as practicable to the provisions contained herein.

         (g) No Further Adjustment for Reorganization. There shall be no
adjustment of the Conversion Price in case of the issuance of any stock of the
Issuer in a merger, reorganization, acquisition, reclassification,
recapitalization or other similar transaction except as set forth in the above
subparagraphs (a) through (e).

         (h) Deferral Until Occurrence of Event. In any case in which the above
subparagraphs (a) through (e) require that an adjustment as a result of any
event become effective from and after a record date, the Issuer may elect to
defer until after the occurrence of such event (i) issuing to the Holder of any
shares of Preferred Stock converted after such record date and before the
occurrence of such event the additional shares of Common Stock issuable upon
such conversion over and above the shares issuable on the basis of the
Conversion Price in effect immediately prior to adjustment and (ii) paying to
such Holder any amount in cash in lieu of a fractional share of Common Stock.

         (i) Adjustment After Record Date. If the Issuer shall take a record of
the Holders of its Common Stock for the purpose of entitling them to receive a
dividend or other distribution, and shall thereafter and before the distribution
to shareholders thereof legally abandon its plan to pay or deliver such dividend
or distribution, then thereafter no adjustment in the number of shares of Common
Stock issuable upon exercise of the right of conversion granted by the above
subparagraphs (a) through (e) or in the Conversion Price then in effect shall be
required by reason of the taking of such record.

         (j) Certificate of Adjustment. In each case of an adjustment or
readjustment of the Conversion Price for the number of shares of Common Stock or
other securities issuable upon conversion of the Preferred Stock, the Issuer, at
its expense, shall compute such adjustment or readjustment in accordance with
the provisions hereof and prepare a certificate showing such adjustment or
readjustment, and shall deliver such certificate to each Holder of Preferred
Stock in accordance with the terms of Section 13. The certificate shall set
forth such adjustment or readjustment, showing in detail the facts upon which
such adjustment or readjustment is based.

                                       7

<PAGE>

              (k) Notice of Holders of Certain Events. Upon (i) any taking by
the Issuer of a record of the Holders of any class of securities in accordance
with the terms thereof for the purpose of determining the Holders thereof who
are entitled to receive any dividend or other distribution, or otherwise
participate in any event for which the Conversion Price is adjusted pursuant to
this Section 4, (ii) any subdivision or combination of the outstanding Common
Stock, (iii) any Fundamental Change or (iv) any Liquidation Event, the Issuer
shall mail to each Holder of Preferred Stock at least twenty (20) days prior to
the record date specified therein a notice specifying (A) the date on which any
such record is to be taken for the purpose of such dividend, distribution or
other event and a description of such dividend, distribution or other event, (B)
the date on which any such subdivision, combination, Fundamental Change or
Liquidation Event is expected to become effective, and (C) the date, if any,
that is to be fixed as to when the Holders of Common Stock (or other securities)
shall be entitled to exchange their shares of Common Stock (or other securities)
for securities or other property deliverable upon such subdivision, Fundamental
Change or Liquidation Event.

         4.3 From and after the Effective Date, the Issuer shall at all times
reserve and keep available for issuance upon the conversion of the Preferred
Stock such number of its authorized but unissued shares of Common Stock as will
from time to time be sufficient to permit the conversion of all outstanding
shares of Preferred Stock, and shall take all action required to increase the
authorized number of shares of Common Stock if at any time there shall be
insufficient authorized unissued shares of Common Stock to permit such
reservation or to permit the conversion of all outstanding shares of Preferred
Stock.

         4.4 The issuance or delivery of certificates for Common Stock upon the
conversion of shares of Preferred Stock shall be made without charge to the
converting Holder of shares of Preferred Stock for such certificates or for any
tax in respect of the issuance or delivery of such certificates or the
securities represented thereby, and such certificates shall be issued or
delivered in the respective names of, or in such names as may be directed by,
the Holders of the shares of Preferred Stock converted; provided, however, that
the Issuer 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 such certificate in
a name other than that of the Holder of the shares of Preferred Stock converted,
and the Issuer shall not be required to issue or deliver such certificate unless
or until the Person or Persons requesting the issuance or delivery thereof shall
have paid to the Issuer the amount of such tax or shall have established to the
reasonable satisfaction of the Issuer that such tax has been paid.

5.       Redemption.
         ----------

              (a) On or after the March 18, 2010, the Issuer shall have the
option to redeem, from time to time, all or any portion of the outstanding
shares of Preferred Stock at a price per share equal to the Redemption Price.
The Issuer shall send notice of each such redemption (the "REDEMPTION NOTICE")
as well as the amount of consideration to be paid for each share of Preferred
Stock to be redeemed, to each of the Holders of shares of Preferred Stock at
least thirty (30) and not more than sixty (60) days' prior to the redemption
date (each, a "REDEMPTION DATE") set forth in such notice. On any Redemption
Date, the Issuer shall pay the Redemption Price in cash.

              (b) With respect to each share of the Preferred Stock that the
Issuer elects not to redeem on March 18, 2010 (whether or not the Issuer has
sufficient legally available funds to

                                       8

<PAGE>

effect such redemption), from and after such date, the Dividend Accretion Rate
with respect to each such share shall be increased to twenty percent (20%);
provided, that this increase will not have any effect on a right of a Holder of
Preferred Stock to receive dividends pursuant to Section 2.1(c) to the extent
any such declared dividends are in excess of such increased Dividend Accretion
Rate.

              (c) If on any Redemption Date the shares of Preferred Stock to be
redeemed shall be less than all of the outstanding shares of Preferred Stock on
such date, the shares shall be redeemed pro rata among all Holders of Preferred
Stock based on their holdings as of such Redemption Date with any fractional
shares round to the nearest whole share.

              (d) Any Redemption Notice delivered to Holders of Preferred Stock
shall not in any way limit such Holder's right to convert such Holder's shares
of Preferred Stock into Common Stock in accordance with Section 4 prior to the
applicable Redemption Date.

              (e) (i) On or before the applicable Redemption Date, each Holder
of shares of Preferred Stock to be redeemed shall surrender his certificate or
certificates representing such shares of Preferred Stock (properly endorsed or
assigned, or transferred, if the Issuer shall so require and the Redemption
Notice shall so state) to the Issuer in the manner and at the place designated
in the Redemption Notice.

                  (ii) On the applicable Redemption Date, the Issuer shall pay
         or deliver, upon receipt of such certificates, to the Holder whose name
         appears on such certificate or certificates as the owner thereof, the
         full Redemption Price due such Holder.

                  (iii) The shares represented by each certificate to be
         surrendered shall be automatically (and without any further action of
         the Issuer or the Holder) canceled as of the applicable Redemption Date
         whether or not certificates for such shares are returned to the Issuer.

                  (iv) If fewer than all the shares represented by any such
         certificate are to be redeemed, a new certificate shall be issued
         representing the unredeemed shares, without cost to the Holder,
         together with the amount of cash, if any, in lieu of fractional shares.

              (f) If a Redemption Notice shall have been given as provided in
Section 5.1(a), all rights of the Holders thereof as stockholders of the Issuer
with respect to shares so called for redemption (including but not limited to,
the right to receive dividends on the shares of Preferred Stock to be redeemed,
but excluding for the right to receive from the Issuer the Redemption Price)
shall cease either (i) from and after the Redemption Date (unless the Issuer
shall default in the payment of the Redemption Price, in which case such rights
shall not terminate at the Redemption Date) or (ii) if the Issuer shall so elect
and state in the Redemption Notice, from and after the time and date (which date
shall be the Redemption Date or an earlier date not less than twenty (20) days
after the date of mailing of the Redemption Notice) on which the Issuer shall
irrevocably deposit in trust for the Holders of the shares to be redeemed with a
designated paying agent an amount in cash sufficient to pay at the office of
such paying agent, on the Redemption Date, the Redemption Price. Any money so
deposited with such paying agent that shall not be required for such redemption
shall be returned to the Issuer forthwith. Subject to applicable escheat laws,
any moneys so set aside by the Issuer and unclaimed at the end of one

                                       9

<PAGE>

year from the Redemption Date shall revert to the general funds of the Issuer,
after which reversion the Holders of such shares so called for redemption shall
look only to the general funds of the Issuer for payment of the Redemption Price
without interest. Any interest accrued on funds held by the paying agent shall
be paid to the Issuer from time to time.

              (g) Notwithstanding anything herein to the contrary, the Issuer
shall not be able to exercise its option to redeem all or any portion of the
outstanding Preferred Stock pursuant to this Section 5 unless and until it has
obtained the approval (by written consent or otherwise) of a majority of the
members of a Special Board Committee designated by the Board of Directors of the
Issuer for such purpose.

6.      Liquidation Preference.
        ----------------------

Liquidation Event, before any distribution is made on any Junior Securities,
including, without limitation, the Common Stock. Payments required to be made
pursuant to this Section 6(a) shall be made in cash.

              (b) If, upon any Liquidation Event, the amounts payable with
respect to the Liquidation Preference and the liquidation preference of all
other Parity Securities are not paid in full, the Holders of the Preferred Stock
and the Parity Securities will share pro rata in proportion to the full
distribution to which each is entitled. After the payment of the full
Liquidation Preference, such Holders shall not be entitled to any additional
distribution of assets of the Issuer.

7.       Voting Rights.
         -------------

         7.1 Except as otherwise provided herein or as required by applicable
law, the Holders of the Preferred Stock shall on and after the Effective Date be
entitled to vote on all matters on which the Holders of Common Stock shall be
entitled to vote, in the same manner and with the same effect as the Holders of
Common Stock, voting together with the Holders of Common Stock as a single
class. For this purpose, the Holders of the Preferred Stock shall be given
notice of any meeting of stockholders as to which the Holders of Common Stock
are given notice in accordance with the Bylaws of the Issuer. As to any matter
on which the Holders of the Preferred Stock shall be entitled to vote, each
Holder of Preferred Stock shall be entitled to that number of votes (calculated
as of the close of business on the record date for the meeting of stockholders,
if such matter is subject to a vote at a meeting of stockholders, or on the
execution date of any written consent, if such matter is subject to a written
consent of the stockholders without a meeting of stockholders) equal to the
number of Conversion Shares into which such Holder's shares of Preferred Stock
could be converted pursuant to the provisions of Section 4 hereof (without
giving effect, for purposes of this Section 7.1 only, to Section 4.2(d)).

         of the Preferred Stock;

         purchase any shares of any class or series of Parity Securities), or
         any other class or series of debt securities convertible or
         exchangeable into Common Stock or any other class or series of
         preferred stock, the payment or deemed payment of dividends with
         respect to which (for federal income tax purposes) could reasonably be
         expected to cause the inclusion of dividends accrued, accreted or paid
         with respect to the Preferred Stock pursuant to this Certificate of
         Designations in the taxable income of any Holder of Preferred Stock;

              (c) pay any dividends or purchase, redeem or acquire or retire for

         the outstanding Preferred Stock, voting separately as a class) in
         respect of, any Junior Securities; and

              (d) consummate or agree to consummate any Designated Change of
         Control Event other than any such event that contemplates the Issuer
         making a Change of Control Offer in accordance with Section 9(a).

         Notwithstanding anything to the contrary contained herein, the
provisions of Section 7.2(b) and 7.2(c) will be of no further force or effect
upon the earlier of the date on which (i) less than twenty percent (20%) of the

              (a) Without the consent of any Holder of the Preferred Stock,

9.       Change of Control.
         -----------------

              (a) (i) Upon the occurrence of a Change of Control, the Issuer may
offer (a "CHANGE OF CONTROL OFFER") to repurchase all, but not less than all, of
the outstanding shares of Preferred Stock, if any, at a purchase price per share
in cash equal to the Change of Control Purchase Amount. If the Issuer elects to
make a Change of Control Offer, it shall, within twenty (20) days following the
occurrence of such Change of Control mail a notice to each Holder of shares of
Preferred Stock describing the transaction or transactions that constitute the
Change of Control and offering to repurchase shares of Preferred Stock, on a
date specified in such notice (the "CHANGE OF CONTROL PURCHASE DATE"), which
date shall be no earlier than ninety (90) days and no later than one hundred and
twenty (120) days from the date such notice is mailed, pursuant to the
procedures described in such notice. The Issuer shall comply with the
requirements of Rule 14e-1 under the Exchange Act and any other securities laws
and regulations to the extent such laws and regulations are applicable.

                  (ii) On the Change of Control Purchase Date, the Issuer shall,
         to the extent lawful:

                       (1) accept for payment all shares of Preferred Stock
               properly tendered pursuant to the Change of Control Offer;

                       (2) deposit with the paying agent an amount equal to the
               Change of Control Purchase Amount in respect of all shares of
               Preferred Stock so tendered; and

                       (3) deliver or cause to be delivered to the Transfer
               Agent all certificates for shares of Preferred Stock so accepted
               together with an officer's certificate stating the aggregate
               number of shares being purchased by the Issuer.

                  (iii) The paying agent shall promptly mail or transfer by wire
         transfer to each Holder of shares of Preferred Stock so tendered the
         Change of Control Purchase Amount for such shares of Preferred Stock,
         and the Transfer Agent shall promptly authenticate and mail (or cause
         to be transferred by book entry) to each Holder a new certificate for
         any shares of Preferred Stock not tendered that are represented by the
         surrendered certificate. The Issuer shall notify each Holder of
         Preferred Stock the results of the Change of Control Offer on or as
         soon as practicable after the Change of Control Purchase Date.

         (b) If the Issuer does not make a Change of Control Offer as provided
in Section 9(a), subject to Section 9(d), all of the outstanding shares of
Preferred Stock held by each Holder will automatically be converted into a
number of shares of Common Stock (or, if the Change of Control is a Designated
Change of Control Event, the type of securities or other consideration
distributed to the Holders of Common Stock upon such Change of Control, if
applicable) having a value equal to the Change of Control Purchase Amount (after
giving effect to the Change of Control and the dilution per share of Common
Stock incurred in connection with the automatic conversion contemplated by this
Section 9(b)) effective upon the twenty-first (21st) day following the
occurrence of a Change of Control. Upon any conversion in accordance with this
Section 9(b), all rights with respect to the shares of Preferred Stock so
converted, including the rights, if any, to receive notices, will terminate,
except the rights of Holders thereof to: (i) receive certificates for the number
of shares of Common Stock into which such shares of

                                       12

<PAGE>

Preferred Stock have been converted; and (ii) exercise the rights which they are
entitled as Holders of Common Stock (including any rights to receive a portion
of the consideration to be paid to such Holders in the Change of Control).

         (c) The provisions of this Section 9 that permit the Issuer to make a
Change of Control Offer shall be applicable regardless of whether any other
provisions of this certificate are applicable. Except as set forth in this
paragraph, no Holder of shares of Preferred Stock shall have any right to
require the Issuer to repurchase or redeem the shares of Preferred Stock, in the
event of a takeover, recapitalization or other similar transaction.

         (d) No provision of this Section 9 shall not in any way limit the right
of any Holder of Preferred Stock to convert such Holder's shares of Preferred
Stock into Common Stock in accordance with Section 4 prior to the Change of
Control Purchase Date.

         (e) Notwithstanding anything herein to the contrary, the Issuer shall
not be able to make a Change of Control Offer pursuant to Section 9(a) unless
and until it has obtained the approval (by written consent or otherwise) of a
majority of the members of a Special Board Committee designated by the Board of
Directors of the Issuer for such purpose.

10.      Purchase Offer.
         --------------

         (a) The Issuer shall have the right (but not the obligation), at any
time and from time to time after the second anniversary of the Original Issuance
Date, to offer (the "PURCHASE OFFER") to repurchase all or any part of the
outstanding shares of Preferred Stock at a purchase price per share in cash
equal to the Purchase Offer Amount. In the event the Purchase Offer is for fewer
than all of the outstanding shares of Preferred Stock, the number of shares of
Preferred Stock held by each Holder which shall be subject to the Purchase Offer
shall be selected on a pro rata basis (with any fractional shares being rounded
to the nearest whole share). If the Issuer elects to make a Purchase Offer, the
Issuer shall mail a notice to each Holder of shares of Preferred Stock (with a
copy to the Transfer Agent) offering to repurchase shares of Preferred Stock on
a date specified in such notice (the "PURCHASE PAYMENT DATE"), which date shall
be no earlier than ninety (90) days and no later than one hundred and twenty
(120) days from the date such notice is mailed, pursuant to the procedures
described in such notice. The Issuer shall comply with the requirements of Rule
14e-1 under the Exchange Act and any other securities laws and regulations to
the extent such laws and regulations are applicable.

         (b) On the Purchase Payment Date, the Issuer shall, to the extent
lawful:

         tendered pursuant to the Purchase Offer;

             (ii) deposit with the paying agent an amount equal to the Purchase
         Offer Amount in respect of all shares Preferred Stock so tendered; and

             (iii) deliver or cause to be delivered to the Transfer Agent all
         certificates for shares of Preferred Stock so accepted together with an
         officer's certificate stating the aggregate number of shares being
         purchased by the Issuer.

         (c) The paying agent shall promptly mail or transmit by wire transfer
to each Holder of shares of Preferred Stock so tendered the Purchase Offer
Amount for such shares of

                                       13

<PAGE>

Preferred Stock, and the Transfer Agent shall promptly authenticate and mail (or
cause to be transferred by book entry) to each such Holder a new certificate for
any shares of Preferred Stock not tendered that are represented by the
surrendered certificate. The Issuer shall notify the Holders of Preferred Stock
the results of the Purchase Offer on or as soon as practicable after the
Purchase Payment Date.

         (d) If a Holder of shares of Preferred Stock subject to the Purchase
Offer elects not to, or otherwise fails to, properly tender such amount of such
Holder's shares of Preferred Stock proportionate to the amount of total shares
of Preferred Stock the Issuer has offered to repurchase in the Purchase Offer,
then with respect to each share of such proportionate amount of Preferred Stock
that such Holder fails to tender, from and after the expiration of the Purchase
Offer the Dividend Accretion Rate with respect to each such share shall be
reduced to five percent (5%) per annum; provided, that this reduction shall not
have any effect on the right of a Holder of Preferred Stock to receive dividends
pursuant to Section 2.1(c) to the extent any such declared dividends are in
excess of such reduced Dividend Accretion Rate.

         (e) Nothing in this Section 10 shall in any way limit such Holder's
right to convert such Holder's shares of Preferred Stock into Common Stock in
accordance with Section 4 prior to the Purchase Payment Date.

         (f) Notwithstanding anything herein to the contrary, the Issuer shall
not be able to make a Purchase Offer pursuant to Section 10(a) unless and until
it has obtained the approval (by written consent or otherwise) of a majority of
the members of a Special Board Committee designated by the Board of Directors of
the Issuer for such purpose.

                  SECTION 2.06 Governmental Approvals; Consents. Subject to the

as amended (the "HSR ACT"), (ii) the filing of the Certificate of Designation

Agreement, or the issuance and delivery of the shares of Series A Preferred
Stock or the Conversion Shares.

                  SECTION 2.07 Financial Statements. (a) The Company has
furnished to the Purchasers the unaudited consolidated balance sheet of the
Company and its subsidiaries as of September 30, 2001 (the "INTERIM BALANCE
SHEET") and the related consolidated statements of operations, stockholders'
equity and cash flows for the nine months then ended. All such financial
statements (including but not limited to 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 balance sheet fairly presents in all material respects the consolidated
financial position of the Company and its subsidiaries as of September 30, 2001,
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
nine months ended September 30, 2001.

                  (b) Except as and to the extent (i) reflected on the Interim
Balance Sheet, (ii) incurred since September 30, 2001 in the ordinary course of
business consistent with past practice, (iii) set forth on Schedule 2.07(b) of
the Disclosure Letter, or (iv) as disclosed in the Company SEC Filings, 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.

                  (c) Except as set forth on Schedule 2.07(c) of the Disclosure
Letter or as disclosed in the Company SEC Filings (as defined in Section 2.08),
since September 30, 2001, 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") since the completion of the Company's initial public
offering on February 18, 2000, and the Company has made available to the
Purchasers, as filed with the SEC, complete and accurate copies of (i) the
Annual Report of the Company on Form 10-K for the years ended December 31, 1999
and 2000, and (ii) all other reports, statements and registration statements
(including but not limited to Current Reports on Form 8-K and Quarterly Reports

                                       6
<PAGE>

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, 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 of the Disclosure Letter or in the Company SEC
Filings, and except as otherwise expressly contemplated by this Agreement, since
September 30, 2001, neither the Company nor any of its Subsidiaries has (a)
issued any stock, bonds or other corporate securities, (b) borrowed or
refinanced any indebtedness for borrowed money other than borrowings under (i)
the Amended and Restated Credit Agreement dated as of September 5, 2000 (as
amended from time to time, the "CREDIT AGREEMENT"), among the Company, SAVVIS
Missouri, Nortel Networks Inc. ("NORTEL"), as Administrative Agent, and the
lenders named therein or (ii) the Master Lease Agreement No. 6857500 with
General Electric Credit Corporation, dated as of March 28, 2000, (c) 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, (d) 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 (e) except in connection with this Agreement and the transactions
contemplated hereby, entered into any agreement, letter of intent or similar
undertaking to take any of the actions listed in clauses (a) through (d) above.

                  SECTION 2.10 Actions Pending. Except as set forth on Schedule
2.10 of the Disclosure Letter or in the Company SEC Filings, there is no action,
suit, investigation or proceeding pending or, to the best knowledge of the
Company, threatened against or affecting the Company or any of its Subsidiaries
to which its or any of its Subsidiaries' 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 OF THE KNOWLEDGE OF THE
COMPANY" shall mean the actual knowledge, upon reasonable inquiry, 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

                                       7
<PAGE>

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 or as set forth on Schedule 2.12(i) of the Disclosure Letter, 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 in
the SEC Filings or on Schedule 2.12(ii) of the Disclosure Letter, 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 set
forth on Schedule 2.12(iii) of the Disclosure Letter, 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. Except as set forth on Schedule 2.12(iv) of the
Disclosure Letter, the Company is not a party to any contract or agreement that
would result in an obligation of the Company to make any payments under such
agreement or contract solely as a result of the execution and delivery of this
Agreement or the Investor Rights Agreement or the consummation of any of the
transactions contemplated hereby or thereby (including, but not limited to, the
issuance, sale and delivery of the Preferred Shares or the Conversion Shares).
The Company has heretofore provided true and correct copies of the Material
Agreements to WCAS VIII.

                  SECTION 2.13 Insurance. The Company maintains insurance with
respect to its businesses, properties, officers, directors and employees
customary with industry practices. The Company has heretofore made available for
inspection by WCAS VIII true and complete copies of all such insurance policies.
Such policies are, and will be, on the Closing Date, in full force and effect
and are, and will be upon the Closing, free from any right of termination or
limitation (other than for non-payment) on the part of the insurance carriers.

                  SECTION 2.14 Information Statement. The Information Statement
(and any amendment thereof or supplement thereto), at the date mailed to
stockholders of the Company

                                       8
<PAGE>

and at the time it becomes effective, will (i) not contain any untrue statement
of a material fact or omit to state any material fact required to be stated
therein or necessary in order to make the statements therein, in light of the
circumstances under which they are made, not misleading and (ii) comply in all
material respects with the provisions of the Exchange Act and the rules and
regulations thereunder; except that no representation is made by the Company
with respect to statements made in the Information Statement to the extent based
solely on information supplied in writing by the Purchasers to the Company
specifically for inclusion therein.

                  SECTION 2.15 Offering of the Preferred Shares. Assuming the
accuracy of the representations and warranties of the Purchasers 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, without
limitation, 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 Preferred Shares under the Securities Act or the rules and
regulations of the SEC thereunder) which would require the offering, issuance or
sale of the Preferred Shares to the Purchasers (but not including the resale
thereof) pursuant to this Agreement to be registered under the Securities Act.

                  SECTION 2.16 Related-Party Transactions. Except (i) as set
forth in the Company SEC Filings or as set forth on Schedule 2.16 of the
Disclosure Letter, or (ii) as contemplated hereby, there are no existing
material arrangements or proposed material transactions between the Company and
any Person or entity that the Company would be required to disclose pursuant to
Item 404 of Regulation S-K of the SEC if a proxy statement of the Company were
required to be filed on or as of the date hereof, other than arrangements or
transactions between the Company and any of the Purchasers.

                  SECTION 2.17 Brokers. All negotiations relative to this
Agreement and the transactions contemplated hereby have been carried on by the
Company directly with the Purchasers, without the intervention of any other
Person on behalf of the Company in such manner as to give rise to any valid
claim by any other Person against the Purchasers for a finder's fee, brokerage
commission or similar payment.

              III. REPRESENTATIONS AND WARRANTIES OF THE PURCHASERS

                  Each Purchaser, severally and not jointly, represents and
warrants to the Company on the date hereof and on the Closing Date, as follows:

                  SECTION 3.01 Organization. Such Purchaser (other than any
Purchaser who is an individual) is duly organized, validly existing and in good
standing under the laws of its jurisdiction of organization and has all
requisite corporate, limited liability or limited partnership power and
authority to operate its properties and assets and to carry on its business as
it is now being conducted.

                  SECTION 3.02 Authorization. The execution, delivery and
performance by such Purchaser of this Agreement and the Investor Rights
Agreement, and the purchase and receipt by such Purchaser of the Preferred
Shares being acquired by it hereunder, have been duly authorized by all
requisite action on the part of such Purchaser and will not violate any
provision

                                       9
<PAGE>

of applicable law, any order of any court or other agency of government, the
charter or other governing documents of such Purchaser.

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

                  SECTION 3.04 Investment Representations. (a) Such Purchaser is
acquiring the Preferred Shares being purchased by such Purchaser hereunder for
such Purchaser's own account, for investment, and not with a view toward the
resale or distribution thereof.

                  (b) Such Purchaser understands that it must bear the economic
risk of such Purchaser's investment for an indefinite period of time, because
the Preferred Shares and, when issued upon conversion of Preferred Shares, 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) Such Purchaser has the ability to bear the economic risks
of the investment in the Preferred Shares being purchased hereunder for an
indefinite period of time. Such Purchaser further acknowledges that it 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 Preferred Shares and to obtain additional information
necessary to verify such information or can acquire it without unreasonable
effort or expense.

                  (d) Such Purchaser has such knowledge and experience in
financial and business matters that such Purchaser is capable of evaluating the
merits and risks of its investment in the Preferred Shares. Such Purchaser
further represents that it 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 Preferred Shares, and that any such Purchaser that is a
limited partnership has not been formed solely for the purpose of purchasing the
Preferred Shares.

                  SECTION 3.05 Governmental Approvals; Consents. Except for any
required filing and approval under the HSR Act, no registration or filing with,
or consent or approval of, or other action by, any Governmental Authority is or
will be necessary by the Purchasers for the valid execution, delivery and
performance of this Agreement and the Investor Rights Agreement.

                  SECTION 3.06 Ownership of Senior Notes and Senior Debt. As of
the Closing Date, if such Purchaser is a WCAS Purchaser, such Purchaser owns the
principal amount of Senior Notes and Senior Debt set forth opposite the name of
such Purchaser in the side letter delivered by WCAS VIII to the Company on such
date.

Common Stock;

                  (d) take any action, or knowingly omit to take any action,

untrue, (B) any of the conditions to the obligations of the Purchasers set forth
in Section 6.01 not being satisfied, or (C) the operation of the business of the
Company or its Subsidiaries outside the ordinary course of business consistent
with past practice, giving due regard to the Company's financial condition,
including but not limited to the filing for bankruptcy by Bridge Information

below, all representations and warranties made by any party hereto in this
Agreement or pursuant hereto shall survive for the period commencing on the date

conditions of this Article, the Company hereby agrees to indemnify, defend and
hold the Purchasers harmless from and against all demands, claims, actions or
causes of action, assessments, losses, damages, liabilities, costs and expenses,
including, without limitation, interest, penalties and reasonable attorneys'
fees and expenses (collectively, "DAMAGES"), asserted against, resulting to,
imposed upon or incurred by the Purchasers by reason of or resulting from a
breach of any representation, warranty or covenant of the Company contained in
or made pursuant to this Agreement.

                  (b) Subject to the terms and conditions of this Article VII,
each Purchaser hereby agrees severally and not jointly to indemnify, defend and
hold the Company harmless from and against all Damages asserted against,
resulting to, imposed upon or incurred by the Company by reason of or resulting

contained in or made pursuant to this Agreement.

from the assertion of liability by third parties shall be subject to the
following terms and conditions:

                  (a) within 20 days after receipt of notice of commencement of

together with a copy of such claim, process or other legal pleading, and the
indemnifying party shall have the right to undertake the defense thereof by
representatives of its own choosing;

                  (b) in the event that the indemnifying party, by the 30th day
after receipt of notice of any such claim (or, if earlier, by the tenth day
preceding the day on which an answer or other pleading must be served in order
to prevent judgment by default in favor of the Person asserting such claim),
does not elect to defend against such claim, the party to be indemnified will
(upon further notice to the indemnifying party) have the right to undertake the
defense, compromise or settlement of such claim on behalf of and for the account
and risk of the indemnifying party, subject to the right of the indemnifying
party to assume the defense of such claim at any time prior to settlement,
compromise or final determination thereof, provided that the indemnifying

                                       18
<PAGE>

party shall be given at least 15 days prior written notice of the effectiveness
of any such proposed settlement or compromise;

                  (c) anything in this Section 7.03 to the contrary
notwithstanding (i) if there is a reasonable probability that a claim may
materially and adversely affect the indemnifying party other than as a result of
money damages or other money payments, the indemnifying party shall have the
right, at its own 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
judgment which does not include as an unconditional term thereof the giving by
the claimant or the plaintiff to the party to be indemnified a release from all
liability in respect of such claim; and

                  (d) in connection with any such indemnification, the
indemnified party will cooperate in all reasonable requests of the indemnifying
party.

law or by regulation of any applicable national stock exchange or any SEC
recognized trading market or equivalent foreign exchange or trading market;
provided that any such required disclosure shall only be made, to the extent

                  SECTION 8.06 Governing Law. This Agreement shall be governed

                  (i) by mutual written agreement of the Company and WCAS VIII;

                  (ii) by either the Company or WCAS VIII if the Closing shall
         not have been consummated on or before March 24, 2002, unless extended
         by mutual agreement or unless the failure to consummate the Closing is
         attributable to a failure on the part of the party seeking to terminate
         this Agreement to perform any obligation required to be performed by
         such party at or prior to the Closing Date; or

                  (iii) by either the Company or WCAS VIII if consummation of
         the transactions contemplated hereby to be consummated on the Closing
         Date would violate any nonappealable final order, decree or judgment of
         any court or Governmental Authority having competent jurisdiction.

                  (b) The party desiring to terminate this Agreement pursuant to
Section 8.09(a)(ii) or (iii) hereof shall promptly give notice of such

<PAGE>

                  (c) If this Agreement is terminated as permitted by this
Section 8.09, 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 of either party to perform a covenant of such party in 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 8.02, 8.03, 8.04, 8.05, 8.06, and
8.10 shall survive any termination hereof pursuant to this Section 8.09.

                  SECTION 8.10 Amendments and Waivers. (a) Subject to Section
8.11 hereof and footnote 1 of Annex I, any provision of this Agreement may be
amended or waived if, but only if, such amendment or waiver is in writing and is
signed, by the Company and WCAS VIII.

                  (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 8.11 Joinder. At any time between the date hereof and
the Closing, additional third party purchasers may agree to purchase (a) all or
any portion of the Preferred Shares agreed to be purchased for cash by a WCAS
Purchaser on the Closing Date or (b) any of the authorized but unissued
Preferred Shares at the Purchase Price on the Closing Date, in each case by
executing and delivering a joinder agreement in the form attached hereto as
Exhibit D hereto (each, a "JOINDER AGREEMENT"). Each Joinder Agreement, if
executed pursuant to clause (a) in the first sentence of this Section 8.11, will
constitute an effective assignment pursuant to Section 8.08. Upon execution and
delivery of a Joinder Agreement by any such purchaser, such purchaser will be
considered an "Other Purchaser" and a "Purchaser" for purposes of this Agreement
and Annex I hereto will be amended to account for such Preferred Shares to be
purchased by such Other Purchaser pursuant to the Joinder Agreement.

                  SECTION 8.12 Counterparts. This Agreement may be executed in
two or more counterparts, each of which shall be deemed an original, but all of

--------
(1) The calculation of "Aggregate Purchase Price" in this Annex I assumes that
the WCAS Purchasers will collectively pay $95,000,000 (in the form of cash and
the exchange of indebtedness and accrued but unpaid interest thereon) including,
but not limited to, the aggregate principal amount of any Senior Notes held by
such Purchasers (including any Senior Notes issued or issuable as interest on
such Senior Notes) for the Preferred Shares to be purchased by such Purchasers
on the Closing Date. For purposes of the calculation of interest on the Senior
Notes, the Closing Date is assumed to occur on March 15, 2002. To the extent the
Closing occurs on a different date, the actual Aggregate Purchase Price paid by
each WCAS Purchaser will be revised to equal $95,000,000 plus the aggregate
principal amount of all such indebtedness and accrued but unpaid interest
thereon. In accordance with the foregoing, the actual number of Preferred Shares
to be issued to each WCAS Purchaser will be revised to equal the amount of such
Purchaser's Aggregate Purchase Price divided by the Purchase Price; rounded down
to the nearest whole share, with any remaining amount being paid by the Company
to such Purchaser as a Fractional Share Payment. On the Closing Date, with no
further action by the Company or any Purchaser, Annex I will be amended and
restated in its entirety to reflect the actual interest accrued and Preferred
Shares issued.
