                                  SCI SYSTEMS
                          GENERAL TERMS AND CONDITIONS

 1.0      PRODUCT PURCHASE PRICES.

 1.1      Purchase prices ("Purchase Prices") for the Products are set forth on
 Schedule 2 and are effective for the period(s) and on the terms stated.
 Purchase Prices are FOB SCI's Plant of manufacture and are net of all taxes,
 duties, and all other charges.

 1.2      Purchase Prices will be reviewed by Network Engines and SCI as
 follows: Commodity prices will be reviewed monthly, items on allocation will be
 reviewed monthly, all other items will be reviewed quarterly. Commodities are
 defined as Processors, Memory Modules, Disk Drives, and CD Rom Drives. Prices
 will be increased or decreased as appropriate. In all cases, all cost
 components of the "Material Overhead" for commodity items shall not exceed
 [**]%. SCI will notify Network Engines Inc. of any industry-wide or sole source
 shortages of components affecting price or delivery schedules.  In such event,
 SCI and Network Engines Inc. will mutually agree on equitable adjustments to
 the Purchase Prices and delivery schedules.

1.3  If the Purchase Prices are based upon minimum quantities of Product
purchased by Network Engines, Inc., and through no fault of SCI, Network Engines
Inc. purchases significantly less than the minimum quantities, the Purchase
Prices will be equitably increased by an amount equal to SCI's verified
additional labor and material costs to manufacture the lesser number of Products
actually purchased by Network Engines Inc.

1.4  If the purchase prices are based on volumes of business as measured in
$U.S., and Network Engines Inc. purchases exceed the agreed upon business
volumes, then SCI shall equitably lower the purchase price in accordance with
the price structure (as defined in schedule 4) at the higher business volumes
for all products produced after the higher business volumes were achieved.

1.5  Network Engines Inc. business volumes shall include all product purchased
directly from SCI by Network Engines Inc. and by Network Engines Inc. licensees.

1.6  SCI agrees to attempt, as a goal, to reduce purchase prices of Network
Engines Inc. products by [**]% per quarter year.  Purchase price reductions can
employ any and all of the following (i) material cost reductions, (ii) labor
cost reductions, and (iii) cost reductions resulting from manufacturing process
improvements. However, design changes for improved manufacturability and
testability will be handled separately, in accordance with paragraph 1.8 below,
and shall not contribute to the [**]% per quarter year purchase price reduction
requirement.  Quarterly reviews will be held between both parties to view the
progress on this target.

  Confidential Materials omitted and filed separately with the Securities and
               Exchange Commission.  Asterisks denote omissions.

1.7  Cost reductions that are a result of process change proposals brought to
the table by SCI will be shared [**]% by both parties for a period of six
months, with [**]% to NEI after that time.  Cost reductions brought to the table
by NEI will be incorporated as soon as mutually agreed to.  Cost reductions for
materials may be incorporated immediately if NEI bears the expense of the
inventory write down.

1.8  Cost reductions attributed to product design changes that are proposed by
SCI after completion of prototype and pre-production phases (i.e. changes that
are defined during steady state production) and implemented by Network Engines
Inc. shall be shared by Network Engines Inc. and SCI as follows: Network Engines
Inc. will receive [**]% of the cost reduction and SCI will receive [**]% of the
cost reduction.

2.0      NETWORK ENGINES INC. PURCHASE ORDERS.

2.1  Products will be manufactured and shipped according to a mutually agreed
schedule. Once agreed to, manufacture and shipment of Products will be in
accordance with Network Engines Inc. Purchase Orders ("Purchase Order(s)"). The
parties agree that TIME AND ACCURACY OF DELIVERY ARE OF THE ESSENCE UNDER THIS
AGREEMENT. Purchase Orders may be issued in hard copy or electronically ("EDI")
and will be issued at intervals as mutually agreed. Issued Purchase Orders are
firm and will cover a minimum of ninety (90) days. Purchase Orders will state
the number of Products to be manufactured and shipped during the period covered
by the Purchase Order, and other terms as mutually agreed. Network Engines shall
provide SCI with the exact configuration of Products to be shipped to NEI
customers with two to three days lead time.

2.2  Network Engines Inc. will provide a rolling 90 day forecast of product
purchases beyond ninety (90) days for planning purposes only. These are not
firm, and will be issued at thirty day intervals.

2.3  SCI will purchase material to manufacture Products according to the
quantity and delivery schedules set forth in Purchase Orders in effect from time
to time during the term of this Agreement. SCI will purchase material for the
Products according to Network Engines Inc.'s Approved Vendor List ("AVL"). With
Network Engines Inc.'s prior written consent, SCI may purchase material in
excess of Purchase Order requirements, such as long lead time components or
components which can be purchased in volume at a lower price.

3.0      PAYMENT TERMS.

Payment terms are net thirty (30) days from invoice date in United States
dollars. Invoices shall state the correct amount of Product and price, reference
Network Engine's P.O. number, and reference SCI's Packing Slip number. The
invoice date shall be no earlier than the ship date. Payments are not subject to
off-set or setoff. Acceptance of a partial payment

<PAGE>

   Confidential Materials omitted and filed separately with the Securities and
               Exchange Commission.  Asterisks denote omissions.

will not be a waiver of the right to be paid the remainder due. The parties
agree that TIME IS OF THE ESSENCE UNDER THIS AGREEMENT, AS IT RELATES TO
PAYMENTS TO SCI.

3.1  The parties acknowledge that in previous business done between Network
Engines and SCI, SCI has required Network Engines to post a standby Letter of
Credit to guarantee payment. Upon the closing of Network Engines' initial public
offering of stock, SCI shall no longer require such standby Letter of Credit
with regard to any payments hereunder.


4.0      WARRANTIES, REMEDIES, LIMITATION OF LIABILITY.

4.1  SCI warrants to Network Engines Inc. that each Product shall be free from
defects in workmanship and materials for [**] months from the Product ship date
(the "Product Warranty"). SCI shall also pass on to Network Engines, as
permitted, any component manufacturer's warranties. Additionally, SCI warrants
to Network Engines Inc. that each "Lot" of product produced will meet a quality
level of not more than "[**] defective parts per million" as measured by the
Product Acceptance tests in paragraph 4.1.2.

4.1.1 The materials portion of the Product Warranty shall not apply to  (ii)
Product that is abused, damaged, altered or misused other than by SCI, or (iii)
Product damaged by external causes not directly contributed to by SCI.

4.1.2 Products shall be considered free from defects in workmanship if they are
manufactured in accordance with SCI's manufacturing workmanship standards,
conform to the Product specifications, and successfully complete Network Engines
Inc. documented Product Acceptance Tests. These tests are system level tests
performed after successful completion of A.T.E and Functional tests. These tests
may be performed at SCI and/or Network Engines Inc. integration facility.
Network Engines Inc. may perform additional acceptance testing which measures a
different array of performance criteria, but the parties agree that the
documented Network Engines Inc. Product Acceptance Tests will be the measurement
standard to determine if the Product meets specifications at the time of
testing. Product acceptance tests will be reviewed quarterly and revised upon
mutual agreement.

4.2.1 ALL CLAIMS FOR BREACH OF WARRANTY MUST BE RECEIVED BY SCI NO LATER THAN
THIRTY (30) DAYS AFTER THE EXPIRATION OF THE WARRANTY PERIOD FOR THE PRODUCT.

4.2.2 THE PRODUCT WARRANTY IS THE ONLY WARRANTY GIVEN BY SCI. SCI MAKES, AND
NETWORK ENGINES INC. RECEIVES, NO OTHER WARRANTY EITHER EXPRESSED OR IMPLIED.
ALL WARRANTIES OF MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE OR USE,
AND ALL IMPLIED

<PAGE>

WARRANTIES OF TITLE FOR ANY CONSIGNED OR NETWORK ENGINES INC. SUPPLIED
MATERIALS, ARE EXPRESSLY DISCLAIMED AND EXCLUDED HEREFROM.

4.2.3 UNLESS EXPRESSLY AGREED TO BY SCI IN WRITING, SCI MAKES NO WARRANTY THAT
THE PRODUCTS WILL (i) MEET ANY SPECIFICATION NOT MADE KNOWN TO AND AGREED TO BY
SCI, OR (ii) RECEIVE THE APPROVAL OF OR BE CERTIFIED BY UNDERWRITERS LABORATORY,
ANY FEDERAL, STATE, LOCAL OR FOREIGN GOVERNMENT AGENCY (INCLUDING WITHOUT
LIMITATION THE FEDERAL COMMUNICATIONS COMMISSION) OR ANY OTHER PERSON OR ENTITY
("REGULATORY STANDARDS").  SCI ASSUMES NO RESPONSIBILITY FOR OBTAINING SUCH
APPROVALS OR CERTIFICATIONS, OR MEETING SUCH SPECIFICATIONS. NOTWITHSTANDING THE
FOREGOING, HOWEVER, SCI WARRANTS THAT IT'S MANUFACTURING PROCESS  WILL NOT ALTER
REGULATORY STANDARDS IF NETWORK ENGINES HAS QUALIFED THE PRODUCTS FOR SUCH
STANDARDS.

4.3   Network Engines Inc.'s exclusive remedy for any breach of the Product
Warranty shall be, at SCI's option, repair by SCI at The facility of original
manufacture, or return of the Purchase Price.

4.4   SCI's warranty obligations will cease only upon completion of the agreed
upon warranty period or upon such time that Network Engines has removed its test
equipment from SCI's premises such that SCI no longer has the test capability to
perform the warranty obligation.

4.5   Network Engines Inc. warrants to SCI that any documentation or other data
that it provides SCI to manufacture the Products is accurate and complete,
unless Network Engines Inc. informs SCI otherwise.

4.6   SCI will repair Products which are outside the warranty period  or
otherwise excluded from Warranty coverage, on mutually agreed prices and terms
and conditions.

4.7   SCI shall maintain the status of the manufacturing organization relevant
to this Agreement as ISO 9002 Certified for the duration of this Agreement.

  Confidential Materials omitted and filed separately with the Securities and
               Exchange Commission.  Asterisks denote omissions.

5.0      INSPECTION.

5.1  Network Engines Inc. is required to inspect each shipment of Products and
give SCI written notice of any defects or count or other discrepancies within
forty five (45) days of receipt.  If Network Engines Inc. does not inspect
Products within forty five (45) days, the Products will be considered accepted
by Network Engines Inc.; any Product defects reported after forty five (45) days
will be covered by the warranty provisions of this Agreement.  Network Engines
Inc. will follow SCI's RMA procedure for return of Products. Discrepant product
returned to SCI via the SCI RMA process shall be dispositioned in accordance
with paragraph 4.3 within 30 days of SCI issuing the RMA. Network Engines shall
receive a  payment credit as part of an RMA, SCI shall re-invoice Network
Engines at the time that it ships repaired or replacement Products. SCI will
also issue a report with each dispositioned product that specifies the root
cause of the failure, the corrective action taken, and the process correction
taken at SCI to prevent recurrence of specific failure.

6.0      RESCHEDULING AND CANCELLATION.

6.1  Network Engines Inc. may increase, decrease or reschedule Products
previously released for production on agreed terms and any costs (if any)
mutually agreed to. Should Network Engines decrease or reschedule Products
previously released for production, Networks Engines' sole liability shall be to
pay for labor costs actually expended and for material cancellation or
rescheduling charges that SCI cannot avoid, despite it's use of commercially
reasonable efforts.

6.2  Network Engines Inc. may not cancel production of Products within [**] days
of their scheduled ship dates. SCI will; however, make commercially reasonable
efforts to accommodate any requests by Network Engines to reconfigure Products
at any time prior to ship date. No reconfigurations will take place until the
Parties have reached mutual agreement on schedule impacts and price adjustments.
Network Engines Inc. may reschedule production of Products within [**] days of
ship date by as much as [**] days. Network Engines Inc. may cancel Purchase
Orders outside the [**] day production period but will be responsible for the
Termination Inventory and handling charges provided for in Article 9 below.

7.0  NON-RECURRING ENGINEERING CHARGES.

7.1  Network Engines Inc. and SCI will mutually agree on SCI provided non-
recurring engineering charges and set-up fees ("NRE") required to manufacture
the Products. NRE charges will be billed to Network Engines Inc. as mutually
agreed upon.

<PAGE>

7.2  Network Engines will own all test equipment, fixtures, tools and other
materials and equipment ("Equipment") that it pays for under this Agreement. SCI
shall take due care of such Equipment while it is in SCI's possession. SCI shall
promptly return all Equipment to Network Engines or its designee upon request
from Network Engines. SCI acknowledges that it has and shall have no right to
retain any Equipment as security or set-off for any amounts or obligations owed
by Network Engines to SCI, and that Network Engines would be irreparably harmed
by any delay in the return of Equipment.

8.0      CHANGES TO THE PRODUCTS.

8.1 SCI will not make any changes to the Products without Network Engines Inc.'s
prior written authorization. SCI will make Network Engines Inc. requested
engineering changes ("EC") to the Products. An EC request will include
sufficient information for evaluation of its feasibility and cost impact. SCI
will respond to EC requests in writing and provide cost and other relevant data
within a time period that is reasonable considering the magnitude of the EC.

8.2  Network Engines Inc. may from time to time change the specifications for
the Products or the work required of SCI hereunder and SCI agrees to make
commercially reasonable efforts to comply. If changes result in a change in
SCI's costs or in the time for performance, an adjustment will be made. Any
adjustment must be in writing and SCI shall not be required to implement such
change until the Parties have mutually agreed upon the price.

9.0      INVENTORY INDEMNIFICATION.

9.1 Upon cancellation of a Purchase Order, or upon expiration of this Agreement
or termination of this Agreement for any reason, Network Engines Inc. shall be
responsible for:

          (i)   all finished Products scheduled for shipment within the thirty
(30) days immediately following SCI's receipt of the cancellation or termination
notice (the "Notice");

          (ii)  all work-in-process, scheduled in accordance with Network
Engines Inc. cancelled purchase order and SCI's agreed upon lead times for
production of Network Engines Inc. product, at receipt of the Notice. Network
Engines shall not pay finished Product fees under subparagraph (i) above, or
work-in-progress fees as specified in this subparagraph, for Products built in
advance of SCI's agreed-upon lead-times; and

          (iii) all components, subassemblies and other material purchased in
accordance with SCI's agreed upon lead times for production of Network Engines
Inc. product and to fill a Purchase Order or authorized to be purchased by
Network Engines Inc. which are on hand or on order at receipt of the Notice.
Without limitation this includes Piece Part Inventory made obsolete or excessive
due to changes to the specifications or Products, minimum buy quantities, and
reel quantities. Items (i)-(iii) are referred to as the "Termination Inventory".
In calculating the quantity of finished Products under (i) above, Products
rescheduled for

<PAGE>

manufacture and shipment during the sixty (60) days immediately prior to receipt
of the Notice may be counted by SCI.

9.2  SCI will make every reasonable effort to use the Termination Inventory on
other programs at the Plant where the Products are manufactured, and other SCI
plants world wide, will cancel all outstanding material orders with vendors, and
will attempt to return piece parts to vendors. Network Engines Inc. will be
responsible for agreed upon shipping costs, re-stocking fees, and cancellation
fees actually incurred by SCI to cancel or return any portion of the Termination
Inventory to vendors.

9.3  Within thirty (30) days from termination or cancellation, SCI will document
the Termination Inventory to Network Engines Inc. Network Engines Inc. and SCI
will review and agree on the contents of the Termination Inventory. SCI will
then ship the Termination Inventory and invoice Network Engines Inc., who will
purchase the Termination Inventory remaining after vendor cancellations and
returns and after other program use, as follows: (i) for Piece Part Inventory
and authorized long lead time components, at SCI's standard cost, (ii) for WIP,
at a reasonable pro rata percentage of the finished Product purchase price; and
(iii) for finished Product, at the purchase price in effect at termination or
cancellation. Network Engines Inc. will be responsible for any negative price
differentials between the price SCI paid for the Piece Part Inventory and
authorized long lead time components and the price at which SCI was able to
return and/or utilize the items on other programs. SCI will credit Network
Engines Inc. for any positive price differentials.

10.0     TERM AND TERMINATION.

10.1 The term of this Agreement shall be one (1) year from the Effective Date
and, unless terminated as provided for below, will be automatically renewed for
one (1) year periods thereafter. Either party must give the other six months
notice of its intent not to renew.

10.2 This Agreement may be terminated by either party upon the occurrence of any
one or more of the following events: (1) failure by either party to perform any
of its material performance obligations under this Agreement and to cure such
failure within sixty (60) days after receipt of written notice describing the
failure in sufficient detail, or if the failure cannot be completely cured
within sixty (60) days, failure to make substantial progress towards a cure
within the sixty (60) day period; or (2) entering into or filing of a petition,
arrangement of proceeding seeking: an order for relief under the bankruptcy laws
of the United States or similar laws of any other jurisdiction; a receivership
for any of its assets; a composition with or assignment for the benefit of its
creditors; a readjustment or debt; or its dissolution or liquidation. This
Agreement will apply to all Products purchased during the six (6) month period
immediately following termination. SCI agrees that it shall cooperate with any
new party that Network Engines has selected to manufacture the Products
(including Network Engines itself) in order to assure a smooth transition of
manufacturing responsibilities and capability, and shall promptly upon request
turn over to such party any and all Equipment (as defined above in Section 7.2),
information, documentation, and/or other materials belonging or pertaining to
Network Engines.

<PAGE>

Upon SCI's demand, Network Engines Inc. will promptly defend, indemnify and
hold SCI, its officers, directors, employees, agents, successors and assigns,
harmless from and against every kind of cost, expense or loss (including
attorneys' fees and legal costs) directly relating to any claim or threatened
claim ("Claims"):  (a) that any Product or portion of a Product violates the

<PAGE>

11.4  SCI's liability for any Product claim shall not exceed the purchase price
of the Products for which the claim is made.

IN NO EVENT SHALL EITHER PARTY  BE LIABLE TO THE OTHER PARTY  OR A THIRD PARTY
FOR ANY SPECIAL, INCIDENTAL, PUNITIVE OR CONSEQUENTIAL DAMAGES, WHETHER BASED
UPON CONTRACT, TORT, OR ANY OTHER LEGAL THEORY (INCLUDING WITHOUT LIMITATION
LOST PROFITS AND OPPORTUNITY).

11.5  This Agreement is intended solely for the benefit of the executing
parties and their permitted successors and assigns.  No other person or entity

11.6  Neither party may sell, transfer or assign any right, duty or obligation
granted or imposed upon it under this Agreement without the prior written
consent of the other party.

11.7  The parties agree that transmission of data by EDI (electronic data
interchange) will not occur until a separate agreement governing such
transmissions is executed.  Upon  execution, such EDI agreement will become an
attachment to this Agreement.

11.8  Neither party shall be liable for damages and costs to the other party
arising out of delays or failures to perform under this Agreement if such
delays or failures result from causes beyond the reasonable control of a party,
and are not caused by an act or omission of such party.  Notice of any such
delays or failures and explanation of their causes must be given to the other
party within five (5) days of the occurrence.  As soon as it is reasonably
apparent that the occurrence will likely cause a delay of more than ninety (90)
days, the party against whom this section is invoked shall have the right to
terminate the affected installments under any Purchase Order.  If Network
Engines Inc. is the party claiming the force majeure event, Network Engines
Inc. shall be liable for any applicable cancellation charges and be responsible
for termination obligations, both as provided for in this Agreement.  This
force majeure provision may not be invoked for failure or inability to make a
payment under this Agreement.

settled, both parties submit to the personal jurisdiction and venue of
<PAGE>

the states and U.S. federal court districts within which the SCI Plant
manufacturing the Products is located, and within which Network Engines Inc.'s
facility issuing the Purchase Orders is located, for the limited purpose of
litigating such differences.

11.11  Prior to either party commencing any legal action under this Agreement,
the parties agree to try, in good faith, to settle the dispute amicably between
them.  If after 30 days, the dispute has not been settled to the satisfaction of
both parties, then the parties agree to engage a third party mediator, to help
settle the matter.  Either party may demand a meeting with a mediator to be held
within thirty days of the demand, and each party shall appoint a representative
of at least the Vice Presidential level who shall personally attend the meeting.
The mediation will be held at a location convenient to both parties and each
party will be responsible for their own costs and expenses, except that the
costs of the mediation will be shared equally between them.
