                           GENERAL PURCHASE AGREEMENT

Egenera, Inc. ("Egenera"), 165 Forest St., Marlboro, MA 01752, and the customer
identified below ("Customer") agree that this General Purchase Agreement ("GPA")
shall govern any Equipment, Egenera Software and services listed on any Order to
be shipped within the United States of America and accepted by Egenera on or
after the date of the last signature below (the "Effective Date").

1. DEFINITIONS

"Order" means a document (typically Customer's purchase order), which is signed
by Customer, specifies Product and related services that Customer seeks to
obtain from Egenera and the related pricing and sufficient other information to
complete the transaction.

"Equipment" means the hardware identified on an Order accepted by Egenera.

"Egenera Software" means software owned by Egenera, including firmware or
materials embedded in the Equipment or identified on an Order accepted by
Egenera, and related documentation (including CD-ROM duplicates), but excluding
any Third Party Materials.

"CRU" means "Customer Replaceable Unit" and is an Equipment component designed
for replacement by the customer.

"RFU" means "Field Replaceable Unit" and is an Equipment component designed for
replacement by Egenera.

"Installation Services" means (i) "Basic Set-Up" (setting up the Equipment,
powering up the Equipment, and booting up the operating system), (ii) a training
course (titled "Foundations"), and (iii) two hours' on-site configuration
consultation, all performed on the same business day. Except as otherwise
agreed, Customer shall be solely responsible for supply and maintenance of an
appropriate environment (including power, network and telephone connections,
etc.) for Equipment.

"Open Source Materials" means Third Party Materials supplied under open-source
software license agreements, such as the GNU Public License, including any
modifications to such software made by Egenera.

<PAGE>

"Third Party Material" means software provided by Egenera to Customer which is
specifically labeled as being provided by and/or owned other than by Egenera,
including Open Source Materials.

"Software" means Egenera Software and Third Party Materials.

2. ORDERING, PRICING AND PAYMENT. All Orders shall reference this GPA and are
subject to acceptance by Egenera. Upon acceptance by Egenera, Orders may not be
cancelled by Customer.

The terms and conditions of this GPA shall apply to each order accepted or
shipped by Egenera hereunder. Any terms or conditions appearing on the face or
reverse side of any purchase order, acknowledgement, or confirmation that are
different from or in addition to those required hereunder shall not be binding
on the parties, even if signed and returned, unless both parties hereto
expressly agree in a separate writing to be bound by such separate or additional
terms and conditions.

Customer shall pay Egenera the price, stated on an accepted Order and also pay
or reimburse Egenera for all related taxes or withholdings, except for those
based on Egenera's net income, or provide Egenera with an appropriate exemption
certificate. All amounts are due in United States currency and in full thirty
(30) days after receipt of Egenera's invoice following Acceptance as described
in Section 3 below. Egenera reserves the right to cancel or suspend any orders
placed by Customer and accepted by Egenera, or refuse or delay shipment thereof,
if Customer fails to make any payment as provided herein or in any invoice or
otherwise to comply with the terms and conditions of this Agreement.

Customer may authorize its affiliates to place Orders hereunder by identifying
such affiliates to Egenera. An affiliate that is controlled by, is under common
control with, or controls ("control" means more than 50% ownership of the
outstanding stock or similar interest) Customer may place an Order. Customer
guarantees its affiliate's compliance with the obligations of this GPA.

3. DELIVERY AND ACCEPTANCE. Title of Equipment and the media for Egenera
Software, free and clear of all liens and encumbrances, and risk of loss for
Equipment, media and embedded Egenera Software shall transfer to Customer upon
Egenera's delivery at Egenera's plants to a common carrier selected by Customer
unless otherwise indicated in the Order. Customer shall pay all shipment related
charges and transit insurance. Unless Customer advises Egenera to the contrary
in writing, Egenera shall not make partial shipments of Customer's orders to be
separately invoiced and paid for when due. If Customer directs Egenera to make
partial shipments, reasonable delay in delivery of any installment shall not
relieve Customer of its obligation to accept the remaining deliveries. In the
case of installment deliveries of materials necessary in order to make prior
shipments usable, acceptance of each installment shall occur upon acceptance of
the last installment necessary to make such shipment usable. Egenera shall use
reasonable efforts to meet Customer's requested delivery schedules for the
Products. Should orders for Products exceed Egenera's available inventory,
Egenera will allocate its available inventory and make deliveries on a basis
Egenera deems equitable, in its sole discretion, and without liability to
Customer on account of the method of allocation chosen or its implementation.

                                       2
<PAGE>

Acceptance of Equipment that Egenera is paid to install occurs (i) upon
successful completion of Egenera's standard installation procedures that
demonstrate conformance to the applicable Egenera-published specifications.
There are no Acceptance criteria for any Product for which Installation Services
are not provided, or for any Product for which the Customer has delayed
installation beyond (10) business days.

4. STANDARD WARRANTY

EQUIPMENT AND EGENERA SOFTWARE. Egenera warrants that Equipment and Egenera
Software will, for a period of one (1) year after Acceptance, perform in
accordance with the applicable Egenera-published specifications. Equipment
upgrades are warrantied for a period of one (1) year from the date of shipment.

This warranty does not apply to problems that arise from (i) accident or abuse,
(ii) interoperation with products not specified or provided by Egenera, (iii)
improper installation or modification by other than Egenera, or (iv) use in an
environment or in a manner or for a purpose for which a Product was not
designed.

Customer should provide remote dial-up access to each system purchased. A login
and password are required to establish access. Failure to provide a dial-up
connection may impact response and resolution time. In the event the Customer
has not provided dial-up access and an Egenera Support Engineer is required on
site due to inability to remotely access the system, Time and Material charges
(at the rate of $[**] per hour, with a [**] hour minimum) will be incurred for
the on-site service, unless Customer is enrolled in a support program that
includes on-site service. Reimbursement of travel and any other expenses shall
be subject to Customer's prior written approval.

Egenera does not warrant that the operation of Egenera Software will be
uninterrupted or error free, or that all defects can be corrected. Egenera does
not warrant any Third Party Material.

Any replacement Equipment parts will be comparable in function and performance
to the original part or Equipment, and be warranted for the remainder of the
original warranty period, or for 90 days, whichever is greater. All replaced
Product or portions thereof shall be returned to and become the property of
Egenera. Any replaced Product or portions thereof not received by Egenera within
ten (10 business days will be invoiced to the Customer. Egenera may use new and
reconditioned parts made by various manufacturers in performing Equipment
warranty repairs and building replacement products. Egenera is responsible for
shipping and insurance charges on replacement parts shipped to and from
Customer.

Egenera provides post-warrant support services for Equipment and Egenera
Software at an additional charge on separate terms and conditions. This support
covers new releases of Egenera Software and post-warranty equipment and software
repair and error correction. If such separate support is not purchased, Egenera
has no obligations to repair or correct errors reported after the end of the
warranty period. If the Standard Warranty has lapsed and post-warranty support
services have not been purchased, Egenera will only provide and charge for
support services on a per-event basis.

                                       3
<PAGE>

SERVICES. Egenera shall perform Installation Services and all other services in
a workmanlike manner in accordance with generally accepted industry standards.

REMEDIES. Egenera's entire liability and Customer's exclusive remedies under the
warranties described under "STANDARD WARRANTY" shall be for Egenera to, at its
option: (1) provide replacement parts and service necessary to repair the
Equipment, and modify the Software to make it conform to its warranty, (2)
replace the Equipment with comparable Equipment and/or replace any Software with
comparable Software that conforms to the warranties, or, in the case of
services, reperform the services, or (3) refund the amount paid by Customer for
the affected Product in exchange for the return of the Product.

LIMITATIONS AND EXCLUSIONS. EGENERA MAKES NO WARRANTIES OR REPRESENTATIONS
WHATSOEVER WITH RESPECT TO ANY THIRD PARTY MATERIALS. AS BETWEEN EGENERA AND
CLIENT, ANY AND ALL THIRD-PARTY MATERIALS ARE EXPRESSLY PROVIDED "AS IS."

EXCEPT AS EXPRESSLY STATED UNDER "WARRANTY" ABOVE, EGENERA PROVIDES PRODUCTS AND
SERVICES "AS IS" AND MAKES NO OTHER EXPRESS WARRANTIES, WRITTEN OR ORAL, AND ALL
OTHER WARRANTIES ARE SPECIFICALLY EXCLUDED, INCLUDING, BUT NOT LIMITED TO THE
IMPLIED WARRANTY OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, OR
NON-INFRINGEMENT, AND ANY WARRANTY ARISING BY STATUTE, OPERATION OF LAW, COURSE
OF DEALING OR PERFORMANCE, OR USAGE OF TRADE.

5. EGENERA SOFTWARE

LICENSE AND OWNERSHIP. Egenera hereby grants Customer a transferable (as set
forth below) world-wide, perpetual, irrevocable license to use, execute, copy
(as set forth below), display and perform the Egenera Software in connection
with the use of Egenera Equipment. The Egenera Software is owned and copyrighted
by Egenera or its third party suppliers. Customer's license confers no title or
ownership in the Egenera Software and is not a sale of any rights in the Egenera
Software. All ownership rights remain in Egenera or its third party suppliers,
as the case may be.

COPIES. Customer may make reasonable numbers of copies of the object code of the
Egenera Software solely for backup, disaster recovery, or archival purposes or
when copying in an essential step in the authorized use of the Egenera Software.
All copyright and other proprietary or restricted rights notices in the original
Egenera Software must be retained on all copies. Customer may copy any of the
enclosed books or printed materials that are part of the Egenera Software, and
any other user documentation, in support of its use of the Egenera Software and
Equipment.

ADDITIONAL RESTRICTIONS. Customer acknowledges that the Egenera Software may
contain software procedures or other mechanisms ("License Enforcement
Mechanisms") that enforce use restrictions and that may disable functionality of
the Egenera Software upon violation of the terms of this GPA. Egenera agrees
that will not invoke or cause to be invoked, for any reason including
enforcement of a valid contract right, any such License Enforcement Mechanisms.

                                       4
<PAGE>

Except to the extent permitted above, Customer may not: modify, translate,
reverse engineer, decompile, disassemble, or create derivative works based on
the Egenera Software; copy (including copying onto a bulletin board or similar
system) the Egenera Software other than as specified above; rent, lease, grant a
security interest in, or otherwise transfer rights to the Egenera Software
except as set forth in "Transfer" below; modify, disable, attempt to circumvent,
or otherwise interfere with any License Enforcement Mechanisms (and Customer
acknowledges that any attempt to do so may be a violation of applicable law) or
remove any proprietary notices or labels on the Egenera Software; or disclose or
otherwise make available Egenera Software in any form to anyone other than
Customer's employees, consultants or independent contractors. If Customer is
using the Egenera Software in any country in the European Community, the
prohibition against modifying, translating, reverse engineering, decompiling,
disassembling or creating derivative works based on the Egenera Software does
not affect Customer's rights under any legislation implementing the E.C. Council
Directive on the Legal Protection of Computer Programs.

TRANSFER. Customer may transfer the license to the Egenera Software only upon
transfer of the Equipment for which it was supplied, and the Egenera Software
may not be separated for use on other computers or equipment. In the case of the
transfer of the Equipment, Customer may deliver the original and all complete,
partial, or electronically stored copies of the Egenera Software and related
documentation to the transferee. Customer may not retain any copies of the
Egenera Software or related documentation, and any copies have been made which
are not transferred to the transferee must be destroyed. The transferee must
accept these licensing terms as a condition of the transfer. Customer's license
will automatically terminate upon any transfer of the Egenera Software. Customer
has no right to sublicense, loan, rent or lease the Egenera Software. Customer
may receive the Egenera Software in more than one medium, for example CD-ROM or
by internet. Customer may not use or install the other medium on another
hardware product. Egenera Software supplied as an upgrade may be used only in
accordance with this GPA.

RESPONSIBILITY FOR PERSONNEL. Customer shall be fully responsible to Egenera for
the compliance of Customer's employees, consultants or independent contractors
who are given access to the Egenera Software.

THIRD PARTY MATERIALS. Egenera may provide to Customer certain software that is
specifically labeled as being provided by and/or owned other than by Egenera
("Third Party Materials") in connection with the Equipment. It is acknowledged
by Customer that Customer shall be licensing such Third-Party Materials directly
from the third party, including the right to use such Third Party Materials in
connection with the Equipment. Egenera shall make available to Customer the
applicable license agreements for all such Third Party Materials. Certain Third
Party Materials supplied by Egenera are Open Source Materials, and as such are
governed by open-source software license agreements supplied with such Open
Source Materials, such as the GNU Public License. Egenera makes no claim of
ownership of Open Source Materials, and such Open Source Materials are supplied
solely in accordance with the license agreements accompanying such software.
Accordingly, the restrictions under "EGENERA SOFTWARE" concerning modification,
confidentiality and other provisions do not apply to such Open Source Materials.
However, the provisions under "STANDARD WARRANTY - Limitations and Exclusions"
and "LIMITATIONS OF LIABILITY" do apply to all Third Party Materials.

                                       5

6. INDEMNITY. Egenera shall, at its expense, indemnify, defend and hold Customer
and its affiliates, and its and their officers, directors, employees and agents
(collectively, "Customer Indemnities") harmless against any third party claim
that a Product infringes any copyright, trade secret, U.S. trademark or U.S.
patent and pay the resulting costs and damages awarded against Customer by a
court of competent jurisdiction, provided Customer (i) notifies Egenera promptly
in writing of such claim (provided that any delay in notifying Egenera shall not
relieve Egenera of its obligations hereunder except to the extent of any actual
prejudice thereby), (ii) grants Egenera sole control over the defense and
settlement thereof (provided that Egenera shall not enter into any settlement or
consent to any judgment imposing any material obligation on Customer Indemnities
other than the payment of money for which Egenera indemnifies Customer
Indemnities), and (iii) reasonably cooperates in response to an Egenera request
for assistance at Egenera's expense.

Should any Product become, or in Egenera's opinion be likely to become, the
subject of such a claim, Egenera shall, at its option and expense, (a) procure
for Customer the right to make continued use thereof, (b) replace or modify such
so that it becomes non-infringing, or (c) request return and upon receipt
thereof refund the price paid by Customer.

Egenera shall have no liability to the extent the alleged infringement is based
on a combination with products not provided or specified by Egenera; use for a
purpose or in a manner for which the Product was not designed; use of any older
version of the Egenera Software when use of a newer Egenera revision made
available to Customer at no charge would have avoided the infringement; any
modification made without Egenera's written approval; any modifications made by
Egenera pursuant to Customer's specific written instructions unless Egenera knew
of the potential infringement; any intellectual property right owned or licensed
by Customer, or Third Party Materials in their form prior to any modifications
made by Egenera.

THE PROVISIONS UNDER "INDEMNITY" STATE CUSTOMER'S SOLE AND EXCLUSIVE REMEDY AND
EGENERA'S ENTIRE LIABILITY FOR INFRINGEMENT CLAIMS.

7. LIMITATIONS OF LIABILITY. EXCEPT AS PROVIDED OTHERWISE UNDER "INDEMNITY"
ABOVE, EGENERA'S TOTAL LIABILITY AND CUSTOMER'S SOLE AND EXCLUSIVE REMEDY FOR
ANY CLAIM OF ANY TYPE WHATSOEVER, ARISING OUT OF A PRODUCT OR SERVICE PROVIDED
HEREUNDER, SHALL BE LIMITED TO PROVEN DIRECT DAMAGES CAUSED BY EGENERA IN AN
AMOUNT NOT TO EXCEED THE PRICE PAID BY CUSTOMER TO EGENERA FOR THE SPECIFIC
SERVICE (CALCULATED ON AN ANNUAL BASIS, WHEN APPLICABLE) OR PRODUCT FROM WHICH
SUCH CLAIM ARISES.

EXCEPT FOR CLAIMS ARISING UNDER "INDEMNITY" ABOVE, NEITHER PARTY SHALL (A) HAVE
LIABILITY TO THE OTHER FOR ANY SPECIAL, CONSEQUENTIAL, EXEMPLARY, INCIDENTAL, OR
INDIRECT DAMAGES (INCLUDING, BUT NOT LIMITED TO, LOSS OF PROFITS, REVENUES, DATA
AND/OR USE), EVEN IF ADVISED OF THE POSSIBILITY THEREOF; AND (B) BRING ANY CLAIM
BASED ON PRODUCT OR SERVICE PROVIDED HEREUNDER MORE THAN TWO (2) YEARS AFTER THE
CAUSE OF ACTION ACCRUES.

                                       6
<PAGE>

THESE LIMITATIONS SHALL APPLY TO ALL CAUSES OF ACTION UNDER OR RELATING TO THIS
GPA, INCLUDING ANY CLAIM BY OR AGAINST ANY SUBSIDIARY, STOCKHOLDER, OR
AFFILIATE, OR OFFICER, DIRECTOR, EMPLOYEE OR AGENT OF ANY OF THEM.

8. FORCE MAJEURE. If either party is prevented from performing any portion of
this GPA by cause beyond its control, including labor disputes (other than by
the employees, contractors, agents, or suppliers of the party seeking relief
hereunder), civil commotion, war, governmental regulations or control, casualty,
inability to obtain materials or services or acts of God, such defaulting party
will be excused from performance for the period of the delay and for a
reasonable time thereafter, provided such party uses commercially reasonable
efforts to resume performance as soon as practicable.

9. CHOICE OF LAW; ARBITRATION. This GPA is governed by and shall be construed
and enforced in accordance with the law of State of New York, excluding its
conflict of law rules that would result in the application of another forum's
law and The U.N. Convention in Contracts for the International Sale of Goods.
Except for the right of any party to apply to a court of competent jurisdiction
for a temporary restraining order, preliminary injunction, or other equitable
relief to preserve the status quo or prevent irreparable harm, any dispute under
this GPA involving its interpretation or the obligations of any party hereto
shall be determined by binding arbitration in accordance with the commercial
arbitration rules of the AAA, in New York, New York, before a single arbitrator.
The arbitrator shall have the authority to permit discovery, to the extent
deemed appropriate by the arbitrator, upon request of a party. The arbitrator
shall have no power or authority to add to or detract from the agreements of the
parties, and the costs of the arbitration shall be borne equally. The arbitrator
shall have the authority to grant any temporary, preliminary or injunctive
relief in a form substantially similar to that which would otherwise be granted
by a court of law. The arbitrator shall have no authority to award punitive or
consequential damages. The resulting arbitration award may be enforced, or
injunctive relief may be sought, in any court of competent jurisdiction. The
parties expressly stipulate that federal and state courts located in New York
County, New York are courts of competent jurisdiction for this purpose.

10. U.S. GOVERNMENT END USERS. The Software is a "commercial item," as that term
is defined in 48 C.F.R. 12.101 (Oct. 1995), consisting of "commercial computer
software" and "commercial computer software documentation," as such terms are
used in 48 C.F.R. 12.212 (Sept. 1995). Consistent with 48 C.F.R. 12.212 and 48
C.F.R. 227.7202-1 through 227.7202-4 (June 1995), all U.S. Government End Users
acquire the Software with only those rights set forth herein.

11. EXPORT CONTROL. Customer understands that Products provided under this GPA
may be subject to regulations by agencies of the United States Government as
well as laws and regulations of other applicable countries which prohibit export
or diversion of certain technical products to certain countries and individuals.
Customer shall comply in all respects with all applicable export and re-export
restrictions applicable to the Products or related materials.

12. MISCELLANEOUS. Egenera may not identify Customer as a customer except as
required by law or with Customer's prior written consent. Neither party shall
assign this GPA or any

                                       7
<PAGE>

right or delegate any performance without the other party's prior written
consent, which consent shall not be unreasonably withheld. This GPA is the
complete statement of the agreement of the parties with regard to the subject
matter hereof; may be modified only by a writing signed by both parties; and
shall control in case of an inconsistent or conflicting term set forth on an
Order. No waiver shall be deemed a waiver if any prior or subsequent default
hereunder. If any part of this GPA is unenforceable, the validity of the
remaining provisions shall not be affected.

      ADDENDUM 1 TO GENERAL PURCHASE AGREEMENT: SUPPORT SERVICES AGREEMENT

This Addendum 1 to the General Purchase Agreement (the "GPA") between Egenera,
Inc. ("Egenera") and Credit Suisse First Boston Corporation ("Customer") is made
on this 27th day of December, 2001 (the "Effective Date").

SCOPE: This Addendum contains additional terms and conditions for support
services offered with the 1 Year Warranty Extension Program, Enterprise II
Program, Enhanced Warranty Program and the Software Subscription Service
Program. In the event of any ambiguity or conflict between this Addendum and the
GPA or between this Addendum and a Statement of Work for Services, the terms of
the GPA will control. Each Statement of Work entered into hereunder will be
governed by and become part of this Addendum. This Addendum shall continue in
effect throughout the Term of the GPA, unless stated otherwise herein.

1. DEFINITIONS

"Major Releases" are new releases of Egenera Software intended to provide
significant functionality enhancements as well as incorporate cumulative bug
fixes and patches since the most recent release.

"Minor Releases" are new releases of Egenera Software that are intended to
provide incremental functionality enhancements as well as incorporate cumulative
bug fixes and patches since the most recent release.

Capitalized terms in this Addendum shall have the meanings defined in the GPA
unless specifically defined in this Addendum.

2. TERM OF SERVICE

The Enterprise II Program and the Software Subscription Program each commence
upon Acceptance of the related Product. The Enterprise II Program has a term of
two years. The Software Subscription Service Program has a term of one year. The
1 Year Warranty Extension program commences upon expiration of the related
Product's Standard Warranty and has a term of one year. The Enhanced Warranty
can only accompany the Enterprise II Program. The Enhanced Warranty is
conterminous with the Enterprise II Program it accompanies.

If the Standard Warranty has lapsed, Egenera will provide and charge for support
services on a per-event basis. The Customer may purchase additional warranty
service at Egenera's then-current rates, upon inspection and re-certification by
Egenera. A fee may be charged for recertification.

Egenera shall provide Customer at least ninety (90) days notice before
expiration of the support program in which Customer is enrolled. The notice
shall contain the proposed pricing for renewal of the applicable support program
as well as Egenera's other support programs. The proposed pricing for any
renewal item shall not exceed the price of the prior term by more than 3% per
year. Customer shall have until thirty (30) days prior to the expiration of the
then-current

                                       1
<PAGE>

support term to notify Egenera of its election to renew support, either under
its then-current program or other program offered by Egenera. If Customer elects
to renew support, the Enterprise II Program shall renew on a biannual basis and
the 1 Year Warranty Extension shall renew on an annual basis.

The term of service for any additions and/or upgrades to already-purchased
Egenera Software is coterminous. Any replacement Equipment parts will be
comparable in function and performance to the original part or Equipment, and be
warranted for the remainder of the original term of service, or for 90 days,
whichever is greater.

3. TECHNICAL SUPPORT

Technical Support will be provided according to Egenera's then-published summary
descriptions, as they may be amended from time to time, of each warranty and
support services program, provided however, that material changes to the
published summary descriptions shall not be effective until the next renewal
term.

Customer should provide remote dial-up access to each system purchased. A login
and password are required to establish access. Failure to provide a dial-up
connection may impact response and resolution time. In the event the Customer
has not provided dial-up access and an Egenera Support Engineer is required on
site due to inability to remotely access the system, Time and Material charges
(at the rate of $[**] per hour, with a [**] hour minimum) will be incurred for
the on-site service, unless Customer is enrolled in a support program that
includes on-site service. Reimbursement of travel and any other expenses shall
be subject to Customer's prior written approval.

Unless customer has purchased the Enhanced Warranty, Egenera will make
reasonable efforts to arrive at the Customer's site within [**] business hours
of the dispatch. Whenever the Enhanced Warranty is in effect, Egenera will make
reasonable efforts to arrive at the Customer's site within [**] hours of the
dispatch. Certain geographical limitations and common carrier schedules may
affect response time.

4. SOFTWARE UPDATE AND UPGRADE SERVICES

Egenera provides support services under this Addendum for the two most recent
Releases of Egenera Software (referred to as Current Release and One Major
Release Back). A Major Release is considered current until such time as a
subsequent major software release is generally available.

Software Support encompasses changes that are needed to resolve problems that
prevent the system from performing to specifications. At Egenera's discretion,
fixes may take the form of patches, maintenance releases, or point releases.

Egenera's Standard Warranty does not include free Major Releases or Minor
Releases. During the Standard Warranty period, Customer may purchase the
Software Subscription Service in order to obtain when-and-if available Major
Releases and Minor Releases at no additional charge.

                                       2
<PAGE>

The Enterprise II Program includes [**] years of Software Subscription Service.

5. CUSTOMER RESPONSIBILITIES

Customer shall be solely responsible to monitor, maintain, and administer the
Product and Egenera Software.

6. EXCLUSIONS

Support under this Addendum shall not include operating supplies and
accessories. This Addendum does not apply to problems that arise from (i)
accident or abuse, (ii) interoperation with products not specified or provided
by Egenera, (iii) improper installation or modification by other than Egenera,
(iv) use in an environment or in a manner or for purpose for which a Product was
not designed, or (v) failure to implement all previously supplied updates to
Product and/or Egenera Software.

7. WARRANTY

Egenera agrees to perform Services in a workmanlike manner in accordance with
generally accepted industry standards. If Services performed by Egenera prove
not to have been so performed or if Egenera fails to provide the Services or a
portion thereof, Egenera will, at its option, either (i) correct any defects and
deficiencies or (ii) render a full refund or credit (at Customer's election)
based on the original charge for the Services.

THIS SERVICES WARRANTY IS EXCLUSIVE AND IS IN LIEU OF ALL OTHER EXPRESS AND
IMPLIED WARRANTIES INCLUDING, BUT NOT LIMITED TO, WARRANTIES OR MERCHANTABILITY
AND FITNESS FOR A PARTICULAR PURPOSE. CUSTOMER'S SOLE AND EXCLUSIVE REMEDY SHALL
BE EGENERA'S OBLIGATION TO MAKE CORRECTIONS OR GIVE A CREDIT OR REFUND AS SET
FORTH ABOVE IN THIS WARRANTY.

Credit Suisse First Boston Corporation ("Customer") and Egenera, Inc.
("Egenera") hereby amend the above captioned agreement ("Agreement") effective
as of November 1, 2002 as follows:

      1.    Customer and Egenera acknowledge that from time to time Customer's
            international affiliates, including, but not limited to, Credit
            Suisse First Boston Securities (Japan) Limited, may wish to order
            Products and associated support services from Egenera pursuant to
            the terms and conditions of the Agreement, as amended. Under such
            circumstances, Egenera may want the flexibility to have such orders
            placed with either Egenera, Inc. or Egenera International, Inc.
            ("EII"), a wholly owned subsidiary of Egenera. In the event,
            Customer and Egenera agree (i) that such Customer international
            affiliates may order and purchase such Products and, subject to
            Section 2 below, support services directly from, at Egenera's
            discretion, either Egenera or EII, in accordance with the Agreement,
            as amended, (ii) that Egenera or EII, as the case may be, shall
            fulfill such orders in accordance with the Agreement, as amended,
            (iii) that Egenera or EII, as the case may be may subcontract the
            support services ordered by the Customer's international affiliates
            to the Egenera subsidiary that, in Egenera's opinion, is best suited
            to provide such services ("Egenera Servicing Subsidiary"), (iv) that
            all such orders shall otherwise be subject to the terms and
            conditions of the Agreement, as amended, (v) that Customer shall
            guarantee its applicable international affiliate's compliance with
            and performance under the Agreement, as amended, if and only if
            Customer approves in writing the purchase order issued by the
            applicable international affiliate, (vi) that Egenera shall
            guarantee, as applicable, EII's and the applicable Egenera Servicing
            Subsidiary's compliance and performance under the Agreement, as
            amended, (vii) the limitation in the preamble of the Agreement to
            orders to be shipped within the United States of America shall not
            apply to orders placed by Customer's international affiliates and
            accepted by Egenera or EII and (viii) the limitation to U.S.
            trademarks and U.S. patents in Section 6 (Indemnity) shall not
            apply, but instead Egenera's obligations under Section 6 (Indemnity)
            with respect to trademarks and patents shall be limited to
            trademarks and patents under the law of the country in which
            Customer's international affiliate is located.

      2.    Notwithstanding the above, if Customer's international affiliate is
            located in a country where Egenera does not have a local service
            office, then either Egenera and Customer's international affiliate
            shall agree in writing upon service support terms that are
            appropriate under the circumstances or Customer's international
            affiliate may contract directly with an independent local Egenera
            authorized Service Provider to obtain service support on the
            Products.

      3.    Except as expressly modified hereby, the terms and conditions of the
            Agreement remain in full force and effect.

    AMENDED AND RESTATED AMENDMENT NUMBER 2 TO THE GENERAL PURCHASE AGREEMENT
        BETWEEN CREDIT SUISSE FIRST BOSTON CORPORATION AND EGENERA, INC.
                       DATED DECEMBER 31, 2001, AS AMENDED

This Amended and Restated Amendment Number 2 (the "Restated Amendment 2") to the
General Purchase Agreement between Credit Suisse First Boston Corporation and
Egenera, Inc. dated December 31, 2001 as amended on November 1, 2002 and June
27, 2003, (collectively the "Agreement"), is entered into by and between
Egenera, Inc. ("Egenera") and Credit Suisse First Boston LLC, (f/k/a Credit
Suisse First Boston Corporation), a Delaware limited liability company, ("CSFB")
to amend and modify the Agreement. The Effective Date of this Restated Amendment
2 shall be March 31, 2004.

      1.    In the event of a conflict between the terms of the Agreement and
            the terms of this Restated Amendment 2, the terms and conditions of
            this Restated Amendment 2 shall govern.

      2.    Capitalized terms used in this Restated Amendment 2 that Are not
            defined herein have the meanings specified therefore in the
            Agreement.

      3.    The parties acknowledge that CSFB and Egenera have fulfilled their
            respective obligations under paragraph 1 of Amendment Number 2 to
            the General Purchase Agreement dated June 27, 2003 (the "Original
            Amendment 2").

      4.    CSFB agrees that it will purchase an aggregate of $[**] of Products
            and services from Egenera, and take delivery thereof between the
            Effective Date and December 31, 2004 (the "Order Period"). CSFB may
            purchase any Products that Egenera makes commercially available
            during the Order Period. At CSFB's option such purchase may be
            divided into more than one shipment, with delivery requested for one
            or more delivery dates occurring on or before December 31, 2004,
            CSFB shall issue an order for the products and services identified
            in Attachment A on March 31, 2004; provided, however, that (a)
            Egenera shall not invoice CSFB until after the applicable Product
            has been received by CSFB or the applicable service has commenced
            and (b) CSFB may change or modify its order to the extent permitted
            under paragraph 13 below.

      5.    Pricing. CSFB shall have the right to purchase Products through
            December 31, 2005 at the following  discounts [**] percent
            ([**]%) off of the list price of any BladeFrame System and
            associated core components that Egenera makes available and a [**]
            percent ([**]%) discount off of the list price of any processing
            blades that Egenera makes commercially available, independent of
            platform. CSFB agrees to purchase products in accordance with the
            methodology set forth in Attachment B without specificity as to
            platform or Product version or type. The list prices set forth in
            Attachment B shall remain in effect through December 31, 2005,
            provided however that if such list prices decrease between the
            Effective Date of this Restated Amendment 2 and December 31, 2005,
            CSFB shall be charged the lower list price minus the applicable
            discount as described above.

                                                                               1

      6.    Support Services Pricing.

            a.    BladeFrame System Support Services. CSFB may purchase Egenera
                  Enterprise Support Services with 7x24x365 coverage, for any
                  BladeFrame System at an annual price equal to [**] percent
                  ([**]%) of the "Net BladeFrame Price" (as described in
                  Attachment B) of the applicable BladeFrame System (the
                  "BladeFrame System Annual Support Fee") (for example: $[**]
                  per year as in Attachment B), provided CSFB commits to a [**]
                  year initial term. Following the expiration of such initial
                  [**] year term, CSFB may renew Egenera Enterprise support
                  services for additional one (1) year terms at a price per year
                  equal to the BladeFrame System Annual Service Fee for that
                  BladeFrame System ($[**] per year in the example in Attachment
                  B).

            b.    Processing Blade Extended Warranty Services. All Processing
                  Blades purchased under Original Amendment 2 or this Restated
                  Amendment 2 will be covered under Egenera's limited warranty
                  for the first year after delivery. Upon expiration of such
                  warranty or upon expiration of any pre-existing support
                  services term, CSFB my purchase Egenera's standard Extended
                  Warranty Services (as described in Attachment C) for any such
                  Processing Blade at an annual price equal to [**] percent
                  ([**]%) of the "Net Pblade Price" (as described in Attachment
                  B) of the applicable Processing Blade (the "Processing Blade
                  Annual Support Fee") (for example: $[**]per year for the "High
                  -End Two-Way" in Attachment B). After the initial term, CSFB
                  may renew such Extended Warranty Services for any such
                  Processing Blade for additional one (1) year terms at a price
                  per year equal to the Processing Blade Annual Support Fee for
                  that Processing Blade ($[**] per year in the "High-End
                  Two-Way" example in Attachment B).

            c.    BladeFrame System Annual Support Fee. The BladeFrame System
                  Annual Support Fee shall be payable in advance annually. In
                  the event that an order for BladeFrame Systems is placed after
                  January 1st of any calendar year, the BladeFrame System Annual
                  Support Fees for the BladeFrame Systems contained in such
                  order shall be prorated for the months remaining in such
                  calendar year. The BladeFrame System Annual Fee shall then be
                  coterminous from January 1st of the following and all future
                  years.

            d.    Processing Blade Annual Fee. The Processing Blade Annual
                  Support Fee shall be payable in advance annually upon
                  expiration of the one (1) year warranty as described in 6(b)
                  above or upon expiration of the any pre-existing support
                  services term. In the event that the one-year warranty or
                  support services term expires and Extended Warranty Services
                  begin after January 1st of any calendar year, the Processing
                  Blade Annual Support Fee for the applicable Processing Blades
                  shall be prorated for the months remaining in such calendar
                  year. The Processing Blade Annual Support

                                                                               2
<PAGE>

                  Fee shall then be coterminous from January 1st of the
                  following and all future years. In an effort to effectively
                  administer the expiration of one (1) year warranties and the
                  expiration of pre-existing support services terms for all
                  Processing Blades, upon the first anniversary of the shipment
                  date of first order placed and the Original Amendment 2 and
                  upon the first anniversary of the shipment date of the first
                  order placed under this Restated Amendment 2, Egenera shall
                  provide CSFB with an invoice and a report detailing the
                  expiration dates of all of the one (1) year warranties and
                  pre-existing support services terms and the associated
                  prorated Processing Blade Annual Support Fees for the
                  remainder of that calendar year.

      7.    CSFB shall order Processing Blades on an as needed basis. Upon the
            installation of the [**] Processing Blade on a BladeFrame System
            ordered under this Restated Amendment 2, CSFB may request delivery
            of an additional BladeFrame System. Such additional BladeFrame
            System(s) shall include a pair of Harvard Control Blades, a top
            mount for patch panel rack, a static transfer switch, and a chassis
            (including a BladePlane). Egenera shall provide such additional
            BladeFrame Systems to CSFB at a [**] percent ([**]%) discount from
            Egenera's list price therefore. Egenera will ship additional
            BladeFrame Systems immediately upon CSFB's request.

      8.    The Products to be purchased pursuant to paragraph l of Original
            Amendment 2 and paragraph 4 above of this Restated Amendment 2
            include a supply of on-site spares (i.e. spare blades to replace
            failed or malfunctioning blades pending repair or replacement of the
            same if covered by warranty or maintenance services or replacement
            of the same with newly purchased blades if not so covered) for CSFB
            using the following algorithm: Each major data center will receive
            one Control Blade, one Switch Blade and five (5) Processor Blades.
            One (1) spare Processor Blade will be provided for every fifteen
            (15) Processor Blades installed on a BladeFrame System ordered under
            Original Amendment 2 or this Restated Amendment 2. In order to
            ensure these spares are provisioned properly, CSFB will provide a
            list of major data centers where Egenera products purchased under
            Original Amendment 2 or this Restated Amendment 2 will be used. CSFB
            shall pay Egenera [**] percent ([**]%) of the applicable Processing
            Blade list price for the on-site spares provided. Egenera and CSFB
            will periodically review the on-site spares inventory at CSFB in
            order to ensure such inventory mix will provide an adequate supply
            of spare blades for the install base of Egenera Products. Such
            review will take place on a quarterly basis. In the event that CSFB
            and Egenera agree that the inventory of on-site spares needs to be
            increased in order to appropriately support the install base of
            Egenera Products, Egenera will increase the on-site spares inventory
            at no cost to CSFB.

      9.    CSFB may ship, at Egenera's cost, any Processing Blades purchased
            under Original Amendment 2 or this Restated Amendment 2 to Egenera
            to be upgraded. Egenera will factory upgrade the processors on such
            Processing Blades at the

                                                                               3
<PAGE>

            following Not-to-Exceed (NTE) prices. This will apply to those
            Processing Blades that are offered as standard Egenera Processing
            Blade options, and that are in the same family of Intel processors
            as those currently offered in Egenera's 2-way and 4-way blades (e.g.
            2-way 533MHz FSB processor family or 4-way 400 MHz FSB processors).
            For two-way blades, the NTE price is $2,800.00 per Processing Blade.
            This includes time/labor and all materials. For high-end four-way
            blades, the NTE price is $[**] per Processing Blade. For the
            midrange four-way blades, the NTE price is $[**] per blade. There is
            no limit on the number of upgrades that CSFB may order pursuant to
            this paragraph.

      10.   Egenera will offer a credit equal to [**] percent ([**]%) of the
            "Net Pblade Price" (as described in Attachment B) of the applicable
            2-way blades purchased under Original Amendment 2 or this Restated
            Amendment 2, which will be applied as an additional discount against
            the purchase of the replacement blades for any upgrades up to [**]
            months after CSFB's receipt of the applicable Processing Blade. The
            total amount of credit available under this paragraph shall not
            exceed $[**].

      11.   The support service pricing terms set forth in paragraph 6 above
            shall apply, at CSFB's option, to all Products presently under an
            Egenera Enterprise Services Agreement, at the time of renewal of
            such agreement.

      12.   Egenera will waive the [**] percent ([**]%) of list International
            uplift charge for all Europe based purchases. For Asia Pacific, the
            [**] percent ([**]%) of list uplift will remain in effect for
            deliveries in that region.

      13.   CSFB has the right to change or modify its order for Products and
            services issued under this Restated Amendment 2 at any time up to
            thirty (30) days prior to shipment of the applicable Products or
            commencement of the applicable services, provided that the final
            aggregate purchase price and final configurations to be delivered on
            or before December 31, 2004 are equal to or greater than $[**].

      14.   Credit Suisse Financial Services (CSFS) and other affiliates of CSFB
            may purchase Products and services pursuant to the terms and
            conditions herein and any such purchases shall count towards the
            order of $[**] to be issued this Restated Amendment 2 above.

      15.   The terms and conditions contained herein shall apply to all
            purchases of Products and services until December 31, 2005.

      16.   The terms and conditions of the Agreement are further amended as
            follows:

            a.    Section 2 (ORDERING, PRICING AND PAYMENT) of the General
                  Purchase Agreement is amended by deleting the second sentence
                  of the second paragraph and inserting the following language:
                  "Any terms or conditions contained in any shrink-wrap or
                  click-wrap agreement contained in or provided with any Product
                  or any terms or conditions

                                                                               4
<PAGE>

                  appearing on the face or reverse side of any purchase order,
                  acknowledgement or confirmation that are different from or in
                  addition to those required hereunder shall not be binding on
                  the parties, even if agreed to electronically or by use or if
                  signed and returned, unless both parties hereto expressly
                  agree in a separate writing to be bound by such separate or
                  additional term and conditions. CSFB expressly acknowledges
                  and agrees that Egenera's base BladeFrame software package may
                  include Microsoft Corporation's Multipath I/O software
                  ("Microsoft Software"). In the event that CSFB uses such
                  Microsoft Software, CSFB agrees to be subject to the end user
                  license agreement attached hereto as Attachment D.

            b.    Section 2 (ORDERING, PRICING AND PAYMENT) of the General
                  Purchase Agreement is amended by inserting the following
                  language immediately after the first sentence in the third
                  paragraph of Section 2 of the Agreement: "CSFB agrees to
                  provide Egenera with a tax exemption certificate or to pay all
                  taxes properly levied against or upon the equipment, products
                  or services or their use hereunder, exclusive however of
                  personal property taxes, franchise taxes, corporate exercise
                  or corporate privilege, property or license taxes, taxes based
                  on Egenera's net income or the gross revenues of Egenera or
                  other taxes levied on Egenera , which are not required by law
                  to be collected from CSFB, which taxes shall be paid by
                  Egenera. For purposes of CSFB obtaining certain tax benefits,
                  Egenera agrees that CSFB may assign its rights, and delegate
                  its obligations under this Agreement, from time to time, to an
