as trustees under this Declaration and Agreement of Trust (the "Voting
Trustees", which term shall be deemed to include a reference to the successors
as Voting Trustees hereunder).

                              W I T N E S S E T H:
                              - - - - - - - - - -

      WHEREAS, the Stockholders have agreed that it is in their best interests
and the best interests of the Corporation to establish a Voting Trust with
respect to the issued and outstanding shares of common stock of the Corporation
held by them; and

      WHEREAS, the Stockholders have also agreed to certain restrictions on the
transfer of the beneficial interest in the shares of common stock so being
transferred to the Voting Trustees; and

      WHEREAS, the Stockholders have delivered to the Voting Trustees all of the
certificates for capital stock of the Corporation held by the Stockholders;

      NOW, THEREFORE, in consideration for One Dollar ($1.00) and other good and
valuable consideration, the receipt and sufficiency of which is hereby severally
acknowledged, the parties hereto hereby agree as follows:

      1. Creation of Trust.
         -----------------

            (a) The parties hereto acknowledge the deposit with the Voting
Trustees of certificates representing 36,000 shares of the common stock, $.01
par value, of the Corporation, being approximately ten percent (10%) of the
issued and outstanding capital stock of the Corporation (the "Shares"), all of
said certificates being accompanied by suitable endorsements to the Voting
Trustees to permit the transfer of the Shares into the names of the Voting
Trustees. The Voting Trustees shall hold all the Shares IN TRUST for the common
benefit of all the Stockholders of the Corporation who have joined in this
Agreement under the terms and conditions hereinafter set forth.

            (b) The parties hereto hereby further acknowledge delivery to the
Stockholders of certificates in the form annexed hereto as Exhibit A executed by
                                                           ---------
the Voting Trustees ("Voting

                                       1
<PAGE>

Trust Certificates"), certifying to the number of Shares so deposited by the
Stockholders with the Voting Trustees and to be reissued in the names of the
Voting Trustees.

      2. Interests of Voting Trustees. It is expressly understood that the
         ----------------------------
Voting Trustees, in their capacity as such, shall have no beneficial interest in
the equity in the Corporation represented by the Shares, nor in any
distributions paid thereon, whether by way of dividends, distributions, in
liquidation or otherwise, but shall hold all such interests in trust for the
Stockholders.

      3. Powers of Voting Trustees.
         -------------------------

            (a) It shall be the duty of the Voting Trustees to exercise all
rights of a stockholder of the Corporation with respect to the Shares, and to
vote the Shares as the Voting Trustees may determine to be in the best interests
of the Corporation, either in person or by proxy, at all meetings of the
stockholders of the Corporation and to execute any action by written consent,
with respect to all matters which may be brought before such meetings or acted
upon by consent, as fully as each of the Stockholders might have done in the
absence of this Voting Trust Agreement.

            (b) Without limiting the foregoing, the Voting Trustees are
specifically authorized, in the exercise of their unrestricted discretion:

                  (i)   to vote for, or to consent to, any increase or decrease
                        of the capital stock of the Corporation that may
                        lawfully be submitted to the Stockholders for action;

                  (ii)  to vote in favor of approving any merger, merger
                        agreement, consolidation, consolidation agreement,
                        reorganization or recapitalization that may lawfully be
                        submitted to the Stockholders for action; and, upon any
                        merger, consolidation, reorganization or
                        recapitalization becoming effective, to surrender the
                        Shares to the extent proper and requisite; and to
                        receive and to hold under this Agreement any and all
                        voting capital stock of the Corporation or of any other
                        corporation issued in exchange for the Shares, or
                        pursuant to the provisions of any such merger,
                        consolidation, reorganization or recapitalization with
                        respect to the Shares;

                  (iii) to vote in favor of approving any plan for the sale of
                        all or any part of the assets of the Corporation that
                        may be lawfully submitted to the Stockholders for
                        action;

                  (iv)  to vote in favor of the mortgage or pledge of all or
                        substantially all or any part of the assets of the
                        Corporation;

                  (v)   to vote in favor of the liquidation and dissolution of
                        the Corporation; and

                                       2
<PAGE>

                  (vi)  to pledge, assign or transfer the Shares as collateral
                        in connection with any loan made to the Corporation by
                        any bank or other financial institution upon such terms
                        and conditions as said Voting Trustees may assent to,
                        and to sell any Shares free of the beneficial interest
                        of the Stockholders in the manner and upon the terms to
                        which the Voting Trustees may have agreed.

      4. Dividends and Distributions.
         ---------------------------

            (a) Each holder of a Voting Trust Certificate shall be entitled to
receive payment in cash of his pro rata share of the amount of all cash
dividends received by the Voting Trustees, and shall be entitled to receive his
respective pro rata share of all dividends received by the Voting Trustees in a
form other than cash; provided, however, that in case the Voting Trustees
receive any shares of voting capital stock of the Corporation or of any other
corporation issued in exchange for the Shares, issued by way of a dividend upon
the Shares or pursuant to the provisions of any merger, consolidation,
reorganization or recapitalization, they shall hold such shares subject to this
Agreement (and such shares shall hereafter be considered Shares hereunder) and
shall issue Voting Trust Certificates to the respective holders of Voting Trust
Certificates evidencing their beneficial ownership of such Shares.

            (b) Except as otherwise provided in Paragraph (a) above, every
distribution of a dividend received by the Voting Trustees shall be made to the
holders of Voting Trust Certificates appearing of record on the transfer books
kept by the Voting Trustees at the close of business on the day upon which the
holders of stock of the Corporation must have been record owners thereof in
order to entitle them to such dividend. The Trustees may, in their discretion,
direct the Corporation to pay cash dividends directly to the holders of Voting
Trust Certificates entitled thereto.

            (c) If the Voting Trustees sell any or all of the Shares from time
to time, or in the event of a partial or total liquidation of the Corporation
and distribution of the proceeds thereof to the Voting Trustees, the Voting
Trustees shall promptly distribute the net proceeds received by them pro rata
among the registered holders of Voting Trust Certificates as of the close of a
business day reasonably established by the Voting Trustees. If such sale of
Shares was of all the Shares held by the Voting Trustees, or if any such
liquidation was a total liquidation of the Corporation, such distribution shall
be made in exchange for and upon the surrender of all the Voting Trust
Certificates, and upon such distribution, this Agreement shall be terminated in
accordance with Section 14 and all obligations and liabilities of the Voting
Trustees hereunder shall terminate.

      5. Power of Voting Trustees to Contract with Corporation.
         -----------------------------------------------------

            (a) Any Voting Trustee may, as an individual, be a stockholder,
director or officer of the Corporation, and may be a holder of Voting Trust
Certificates; and may be interested, directly or indirectly, in the purchase and
sale of the Corporation's stocks, bonds, debentures and other securities. The
Voting Trustees may vote for themselves as directors and officers of the

                                       3
<PAGE>

Corporation and may receive compensation from the Corporation for services
performed by them for it in those or any other capacities.

            (b) Each Voting Trustee, in his individual capacity, or any concern
in which he may have an interest, may deal with the Corporation as if he was not
a Voting Trustee hereunder, and any such dealing approved by a majority of the
directors of the Corporation, even though elected by the Voting Trustee, shall
be conclusively presumed to be fair to the Corporation.

      6. Liability of Voting Trustees. In holding, disposing of or voting the
         ----------------------------
Shares, the Voting Trustees shall exercise their best judgment from time to time
to elect suitable officers and directors and to act upon such other matters
which may come before them at stockholders' meetings, all to the end that the
affairs of the Corporation shall be properly managed. Nevertheless, the Voting
Trustees assume no responsibility, in their capacity as Voting Trustees, for the
management of the business and affairs of the Corporation or for any action
taken pursuant to votes so cast so long as the Voting Trustees exercise good
faith and are not in willful default of their fiduciary obligation hereunder. No
Voting Trustee shall be liable for any error of law nor for the default of any
other Voting Trustee.

      7. Transfer of Voting Trust Certificates. The Voting Trust Certificates
         -------------------------------------
shall be transferable only on the books of the Voting Trustees, to be kept by
them or their agent, on surrender thereof by the registered holder in person or
by attorney (provided that, if rules are from time to time established by the
Voting Trustees with respect to authorization of attorneys, such surrender shall
be in person or by an attorney so authorized), and until so transferred, the
Voting Trustees may treat the registered holder of a Voting Trust Certificate as
the owner for all purposes whatsoever. The transfer books may be closed by the
Voting Trustees at any time prior to the holding of meetings or the payment of
dividends, or for any other purpose.

      8. Restriction on Transfer of Voting Trust Certificates.
         ----------------------------------------------------

            (a) Except as provided in paragraph (b) hereof, no Stockholder may
sell, pledge, hypothecate, transfer or otherwise dispose of all or any part of
the interest of the Stockholder in the Shares or the Voting Trust Certificates
held by him.

            (b) The restrictions of paragraph (a) shall not apply to:

                  (i)   a transfer on the death of any Stockholder to the
                        decedent's personal representative, heirs or legatees;
                        or

                  (ii)  a transfer by any of the parties to this Agreement to
                        any other party to this Agreement; or

                  (iii) a transfer by the holder of any Voting Trust Certificate
                        made with the written consent of all of the other then
                        holders of Voting Trust Certificates;

                                       4
<PAGE>

provided in each case that such interest in the Shares or Voting Trust
Certificate so transferred shall continue in all respects to be subject to all
the terms, conditions and provisions hereof, unless the holders of all Voting
Trust Certificates otherwise agree.

            (c) Without limiting such rights as the parties may have according
to law, it is specifically agreed that any party to this Agreement shall have
the right to seek injunctive relief for a violation of the restrictions on
transfer of any parry's interest in the Shares or Voting Trust Certificates.

      9. Resignation and Removal of Voting Trustees.
         ------------------------------------------

            (a) Any Voting Trustee may resign at any time by delivering his
written resignation to the other Voting Trustee(s), if any, with a copy of such
written resignation to the Clerk of the Corporation and each person then holding
a Voting Trust Certificate.

            (b) The holders of all of the Voting Trust Certificates may, at a
meeting called for such purpose pursuant to Section 11, remove any Voting
Trustee for cause shown. provided that at such meeting the Voting Trustee shall
be given an opportunity for a hearing on the cause asserted as the basis for
removal.

      10. Vacancy; Successors.
          -------------------

            (a) In the event of the death, declination, resignation or inability
of any of the original Voting Trustees hereunder to serve, the remaining
original Trustee(s) shall be the sole Trustee(s). In the event of the death,
declination, resignation or inability of all the original Trustees to serve,
then Wayne Smith shall serve as Voting Trustee (the "Interim Trustee"). As soon
as practicable, the Interim Trustee shall appoint a new trustee of the Voting
Trust that is mutually acceptable to the executor and/or legal representatives
of the original Voting Trustees' respective estates. After carrying out the
above-stated duties, the Interim Trustee shall resign as trustee of the Voting
Trust. Upon the death, declination, resignation or inability to serve of any of
the alternate Voting Trustees, the remaining Voting Trustees may designate a
successor.

            (b) Upon the acceptance by a new Voting Trustee of his appointment
as a successor Voting Trustee, the title to the trust property and all of the
powers herein given to the Voting Trustees shall vest in the remaining and the
new Voting Trustee without further conveyance or formality.

      11. Meetings of Holders of Voting Trust Certificates. Whenever the vote of
          ------------------------------------------------
the holders of Voting Trust Certificates is required, such vote shall be taken
at a special meeting of such holders called by any Voting Trustee or by Voting
Trust Certificate holders holding more than twenty-five percent (25%) of the
beneficial interest under this Agreement, and such meeting shall be held at the
last designated office of the Voting Trustees. Notice of the time and place of
such

                                       5
<PAGE>

meeting shall be given to all of the holders of Voting Trust Certificates not
less than seven (7) days before the day specified in such notice as the day on
which such meeting shall be held.

      12. Compensation of Voting Trustees. The Voting Trustees are not to

employ counsel and such other assistance as may be convenient in the performance
of their functions. The Voting Trustees may receive from the holders of Voting
Trust Certificates reimbursement or indemnity for and against any and all
claims, expenses and liabilities incurred by them or asserted against them in
connection with or growing out of this Agreement or the discharge of their
duties hereunder. Any such claims, expenses or liabilities shall be charged to
the holders of the Voting Trust Certificates pro rata and may be deducted from
dividends or other distributions to them, or may be made a charge payable as a
condition to the delivery of assets out of trust in exchange for Voting Trust
Certificates as provided herein, and the Voting Trustees shall be entitled to a
lien therefor upon the assets held in trust hereunder for such claim, expenses
and liabilities.

      13. Loss of Voting Trust Certificates. In case of the loss, destruction or
          ---------------------------------
mutilation of a Voting Trust Certificate, the Trustees may issue a duplicate of
such certificate upon receipt of satisfactory evidence of such loss, destruction
or mutilation and an indemnity agreement, if the Voting Trustees so require,
against loss or expense in connection with the issuance of a new Voting Trust
Certificate.

                              NETWORK ENGINES, INC.

                           Restricted Stock Agreement
                     Granted Under 1999 Stock Incentive Plan

      AGREEMENT made this 18th day of November, 1999 (the "Effective Date"),
between Network Engines, Inc., a Delaware corporation (the "Company"), and
Lawrence A. Genovesi (the "Participant").

      For valuable consideration, receipt of which is acknowledged, the parties
hereto agree as follows:

      1.    Purchase of Shares.
            ------------------

      The Company shall issue and sell to the Participant, and the Participant
shall purchase from the Company, subject to the terms and conditions set forth
in this Agreement and in the Company's 1999 Stock Incentive Plan (the "Plan"),
150,000 shares (the "Shares") of common stock, $.01 par value, of the Company
("Common Stock"), at a purchase price of $.60 per share. For the sake of
clarity, such Shares represent shares of Common Stock following the stock split
which the Board of Directors of the Company approved on October 21, 1999. The
aggregate purchase price for the Shares shall be paid by the Participant by
check payable to the order of the Company or by full recourse promissory note
naming the Company as payee (the "Note") provided that the Note shall be payable
on demand and shall bear interest at the minimum applicable federal rate in
effect. Upon receipt by the Company of payment for the Shares, the Company shall
issue to the Participant one or more certificates in the name of the Participant
for the Shares. The Participant agrees that the Shares shall be subject to the
Purchase Options set forth in Section 2, the right of first refusal set forth in
Section 5 and the restrictions on transfer set forth in Section 4 of this
Agreement.

      2.    Purchase Options.
            ----------------

      (a)   As of the Effective Date, 150,000 Shares shall be considered "Future
            Goal Shares," zero (0) shares shall be considered "Vested Shares"
            and zero (0) shares shall be considered "Missed Goal Shares."
            "Unvested Shares" shall mean the total of Future Goal Shares and
            Missed Goal Shares.

      (b)   A "Business Objective", shall mean the goal for each of the
            Company's (i) net revenue and (ii) net profit for each fiscal
            quarter beginning with the

                                       1
<PAGE>

            fiscal quarter ending December 31, 1999 and ending with the fiscal
            quarter ending September 30, 2002 (each, a "Fiscal Quarter"). Such
            Business Objectives shall be established by the Board of Directors
            of the Company no less frequently than once each fiscal year of the
            Company and shall be based on the goals for the Company's Net
            Revenue and Net Profit, respectively, as defined in a business plan
            approved by the Board of Directors. The Board of Directors may, in
            its sole discretion, reduce any Business Objective (i.e., make the
            Business Objective easier for the Company to achieve).

            The Business Objectives by Fiscal Quarter for the Company's fiscal
            year ending September 30,2000 shall be as follows:

            Fiscal Quarter Ending         Net Revenue              Net Income
            ---------------------         -----------              ----------
            December 31, 1999             $3,813,800              $(2,642,000)
            March 31, 2000                $4,200,000              $(3,451,000)
            June 30, 2000                 $7,559,534              $ ( 974,000)
            September 30, 2000            $9,426,667              $ ( 287,000)

            Business Objectives for subsequent fiscal years shall be set by the
            Board of Directors no later than the end of October of such fiscal
            year.

            An "Achieved Business Objective" shall mean the achievement by the
            Company of a Business Objective. A "Missed Business Objective" shall
            mean a Business Objective which the Company did not achieve.

            Achievement of the Business Objectives for a Fiscal Quarter will be
            determined based on the unaudited quarterly financial statements of
            the Company, as approved by the Board of Directors within thirty
            (30) days after the end of such Fiscal Quarter; any subsequent
            adjustments to such financial statements shall have no effect on the
            determination of whether or not a Business Objective for such Fiscal
            Quarter was achieved. Notwithstanding anything to the contrary in
            this Agreement or in the Plan, upon the occurrence of an Acquisition
            Event, as defined in the Plan, both Business Objectives for the
            Fiscal Quarter in which such Acquisition Event occurs shall be
            deemed to be Achieved Business Objectives.

            Failure of the Board of Directors to timely establish Business
            Objectives or approve a business plan shall not affect any
            determination as to the establishment of a Business Objective or the
            achievement of Achieved

                                       2
<PAGE>

            Business Objectives.

            For each Achieved Business Objective, the number of Vested Shares
            shall be increased by 6,250 and the number of Future Goal Shares
            shall be decreased by 6,250. For each Missed Business Objective, the
            number of Missed Goal Shares shall be increased by 6,250 and the
            number of Future Goal Shares shall be decreased by 6,250.

            For the sake of clarity and by way of illustration, zero, one or two
            Business Objectives may be achieved each Fiscal Quarter, thus
            resulting in zero, one or two Achieved Business Objectives each
            Fiscal Quarter. Accordingly, (i) for any Fiscal Quarter in which
            both Business Objectives are achieved, the number of Vested Shares
            shall be increased by 12,500 and the number of Future Goal Shares
            shall be decreased by 12,500; (ii) for any Fiscal Quarter in which
            one Business Objective is achieved and the other Business Objective
            is not achieved, the number of Vested Shares shall be increased by
            6,250, the number of Missed Goal Shares shall be increased by 6,250
            and the number of Future Goal Shares shall be decreased by 12,500;
            and (iii) for any Fiscal Quarter in which neither Business Objective
            is achieved, the number of Missed Goal Shares shall be increased by
            12,500 and the number of Future Goal Shares shall be decreased by
            12,500.

      (c)   At any time, and from time to time, prior to November 18, 2004 (the
            "Lapse Date"), the Company shall have the right and options (the
            "Missed Goal Purchase Options") to purchase from the Participant,
            for a sum of $.60 per share (the "Option Price"), any or all of the
            Missed Goal Shares existing at the time such Missed Goal Purchase
            Option is exercised by the Company. Immediately following such
            exercise, the number of Missed Goal Shares shall be decreased by the
            number of shares purchased by the Company by exercising such Missed
            Goal Purchase Option.

            In the event that the Participant ceases to be employed by the
            Company for any reason or no reason, with or without cause, prior to
            the Lapse Date, the Company shall have the right and option (the
            "Termination Purchase Option", and, together with the Missed Goal
            Purchase Options, the "`Purchase Options", or each, a "Purchase
            Option") to purchase from the Participant, for the aggregate Option
            Price, any or all of the Unvested Shares existing at the time the
            Termination Purchase Option becomes exercisable by the Company.

                                       3

      (d)   For purposes of this Agreement, employment with the Company shall
            include employment with a parent or subsidiary of the Company.

      3.    Exercise of Purchase Options and Closing.
            ----------------------------------------

      (a)   The Company may exercise a Missed Goal Purchase Option by delivering
            or mailing to the Participant (or his estate), at any time, a
            written notice of exercise of a Missed Goal Purchase Option. Such
            notice shall specify the number of Missed Goal Shares to be
            purchased. If and to the extent Missed Goal Purchase Options are not
            so exercised, the Missed Goal Purchase Options shall automatically
            expire and terminate effective upon the Lapse Date.

            The Company may exercise the Termination Purchase Option by
            delivering or mailing to the Participant (or his estate), within 60
            days after the termination of the employment of the Participant with
            the Company, a written notice of exercise of the Termination
            Purchase Option. Such notice shall specify the number of Unvested
            Shares to be purchased. If and to the extent the Termination
            Purchase Option is not so exercised by the giving of such a notice
            within such 60-day period, the Termination Purchase Option shall
            automatically expire and terminate effective upon the expiration of
            such 60-day period.

      (b)   Within 10 days after delivery to the Participant of the Company's
            notice of the exercise of a Purchase Option pursuant to subsection
            (a) above, the Participant (or his estate) shall, pursuant to the
            provisions of the Joint Escrow Instructions referred to in Section
            7, tender to the Company at its principal offices the certificate or
            certificates representing the Shares which the Company has elected
            to purchase in accordance with the terms of this Agreement, duly
            endorsed in blank or with duly endorsed stock powers attached
            thereto, all in form suitable for the transfer of such Shares to the
            Company. Promptly following its receipt of such certificate or
            certificates, the Company shall pay to the Participant the aggregate
            Option Price for such Shares (provided that any delay in making such
            payment shall not invalidate the Company's exercise of the Purchase
            Option with respect to such Shares).

      (c)   After the time at which any Shares are required to be delivered to
            the Company for transfer to the Company pursuant to subsection (b)
            above, the Company shall not pay any dividend to the Participant on
            account of such Shares or permit the Participant to exercise any of
            the privileges or

                                       4
<PAGE>

            rights of a stockholder with respect to such Shares, but shall, in
            so far as permitted by law, treat the Company as the owner of such
            Shares.

      (d)   The Option Price may be payable, at the option of the Company, in
            cancellation of all or a portion of any outstanding indebtedness of
            the Participant to the Company or in cash (by check) or both.

      (e)   The Company shall not purchase any fraction of a Share upon exercise
            of a Purchase Option.

      (f)   The Company may assign its Purchase Options to one or more persons
            or entities.

      4.    Restrictions on Transfer.
            ------------------------

      The Participant shall not sell, assign, transfer, pledge, hypothecate or
otherwise dispose of, by operation of law or otherwise (collectively
"transfer"):

      (a)   any Shares, or any interest therein, that are subject to one or more
            Purchase Options, except that the Participant may transfer such
            Shares (i) to or for the benefit of any spouse, child or grandchild

            Section 4, the Purchase Options and the right of first refusal set
            forth in Section 5) and such permitted transferee shall, as a
            condition to such transfer, deliver to the Company a written
            instrument confirming that such transferee shall be bound by all of
            the terms and conditions of this Agreement or (ii) as part of the
            sale of all or substantially all of the Shares of capital stock of

            --------
            property received by the Participant in connection with such

      5.    Right of First Refusal.
            ----------------------

      The Participant shall, upon the execution of this Agreement, execute joint
Escrow Instructions in the form attached to this Agreement as Exhibit A. The

escrow agent thereunder. The Participant shall deliver to such escrow agent a
stock assignment duly endorsed in blank and hereby instructs the Company to
deliver to such escrow agent, on behalf of the Participant, the certificate(s)
evidencing the Shares issued hereunder. Such materials shall be held by such
escrow agent pursuant to the terms of such joint Escrow Instructions.

      8.    Restrictive Legends.
            -------------------

      All certificates representing Shares shall have affixed thereto legends in
substantially the following form, in addition to any other legends that may be

            "The shares of stock represented by this certificate are subject to
            restrictions on transfer and an option to purchase set forth in a
            certain Restricted Stock Agreement between the corporation and the
            registered owner of these shares (or his predecessor in interest),
            and such Agreement is available for inspection without charge at the
            office of the Secretary of the corporation."

                                       6
<PAGE>

            "The shares represented by this certificate have not been registered
            under the Securities Act of 1933, as amended, and may not be sold,
            transferred or otherwise disposed of in the absence of an effective
            registration statement under such Act or an opinion of counsel
            satisfactory to the corporation to the effect that such registration
            is not required."

      9.    Provisions of the Plan.
            ----------------------

      (a)   This Agreement is subject to the provisions of the Plan, a copy of
            which is furnished to the Participant with this Agreement.

      (b)   As provided in the Plan, upon the occurrence of an Acquisition Event
            (as defined in the Plan), the repurchase and other rights of the
            Company hereunder shall inure to the benefit of the Company's
            successor and shall apply to the cash, securities or other property
            which the Common Stock was converted into or exchanged for pursuant
            to such Acquisition Event in the same manner and to the same extent
            as they applied to the Common Stock hereunder. If, in connection
            with an Acquisition Event, a portion of the cash, securities or
            other property received upon the conversion or exchange of the
            Common Stock subject hereto is to be placed into escrow to secure
            indemnification or similar obligations, the mix between the vested
            and unvested portion of such cash, securities or other property that
            is placed into escrow shall be the same as the mix between the
            vested and unvested portion of such securities or other property
            that is not subject to escrow.

      10.   Investment Representations.
            --------------------------

      The Participant represents, warrants and covenants as follows:

      (a)   The Participant is purchasing the Shares for his own account for
            investment only, and not with a view to, or for sale in connection
            with, any distribution of the Shares in violation of the Securities
            Act, or any rule or regulation under the Securities Act.

      (b)   The Participant has had such opportunity as he has deemed adequate
            to obtain from representatives of the Company such information as is
            necessary to permit him to evaluate the merits and risks of his
            investment in the Company.

                                       7
<PAGE>

      (c)   The Participant has sufficient experience in business, financial and
            investment matters to be able to evaluate the risks involved in the
            purchase of the Shares and to make an informed investment decision
            with respect to such purchase.

      (d)   The Participant can afford a complete loss of the value of the
            Shares and is able to bear the economic risk of holding such Shares
            for an indefinite period.

      (e)   The Participant understands that (i) the Shares have not been
            registered under the Securities Act and are "restricted securities"
            within the meaning of Rule 144 under the Securities Act; (ii) the
            Shares cannot be sold, transferred or otherwise disposed of unless
            they are subsequently registered under the Securities Act or an
            exemption from registration is then available; (iii) in any event,
            the exemption from registration under Rule 144 will not be available
            for at least one year and even then will not be available unless a
            public market then exists for the Common Stock, adequate information
            concerning the Company is then available to the public, and other
            terms and conditions of Rule 144 are complied with; and (iv) there
            is now no registration statement on file with the Securities and
            Exchange Commission with respect to any stock of the Company and the
            Company has no obligation or current intention to register the
            Shares under the Securities Act.

      11.   Withholding Taxes; Section 83(b) Election.
            -----------------------------------------

      (a)   The Participant acknowledges and agrees that the Company has the
            right to deduct from payments of any kind otherwise due to the
            Participant any federal, state or local taxes of any kind required
            by law to be withheld with respect to the purchase of the Shares by
            the Participant or the lapse of the Purchase Option.

      (b)   The Participant has reviewed with the Participant's own tax advisors
            the federal, state, local and foreign tax consequences of this
            investment and the transactions contemplated by this Agreement. The
            Participant is relying solely on such advisors and not on any
            statements or representations of the Company or any of its agents.
            The Participant understands that the Participant (and not the
            Company) shall be responsible for the Participant's own tax
            liability that may arise as a result of this investment or the
            transactions contemplated by this Agreement. The Participant
            understands that it may be beneficial in many circumstances to elect
            to be taxed at the time of the Shares are purchased

                                       8

            rather than when and as the Company's Purchase Option expires by
            filing an election under Section 83(b) of the Code with the IRS
            within 30 days from the date of purchase.

      THE PARTICIPANT ACKNOWLEDGES THAT IT IS THE PARTICIPANT'S SOLE
RESPONSIBILITY AND NOT THE COMPANY'S TO FILE TIMELY THE ELECTION UNDER SECTION
83(b), EVEN IF THE PARTICIPANT REQUESTS THE COMPANY OR ITS REPRESENTATIVES TO
MAKE THIS FILING ON THE PARTICIPANT'S BEHALF.

      12.   No Rights to Employment.
            -----------------------
      The Participant acknowledges and agrees that the vesting of the shares
pursuant to Section 2 hereof is earned only by the achievement by the Company of
the Business Objectives during the period of the Participant's continuing
service as an employee at the will of the Company (not through the act of being
hired or purchasing shares hereunder). The Participant further acknowledges and
agrees that the transactions contemplated hereunder and the vesting schedule set
forth herein do not constitute an express or implied promise of continued
engagement as an employee for the vesting period, for any period, or at all.

      13.   Severability.
            ------------

      The invalidity or unenforceability of any provision of this Agreement
shall not affect the validity or enforceability of any other provision of this
Agreement, and each other provision of this Agreement shall be severable and
enforceable to the extent permitted by law.

      14.   Waiver.
            ------

      Any provision for the benefit of the Company contained in this Agreement
may be waived, either generally or in any particular instance, by the Board of
Directors of the Company.

      15.   Binding Effect.
            --------------

      This Agreement shall be binding upon and inure to the benefit of the
Company and the Participant and their respective heirs, executors,
administrators, legal representatives, successors and assigns, subject to the
restrictions on transfer set forth in Sections 4 and 5 of this Agreement.

Dear Sir:

      As Escrow Agent for Network Engines, Inc., a Delaware corporation (the

directed to hold the documents delivered to you pursuant to the terms of that
certain Restricted Stock Agreement (the "Agreement") of even date herewith, to
which a copy of these Joint Escrow Instructions is attached, in accordance with
the following instructions:

      1. Appointment. Holder irrevocably authorizes the Company to deposit with
         -----------
you any certificates evidencing Shares (as defined in the Agreement) to be held
by you hereunder and any additions and substitutions to said Shares. Holder does
hereby irrevocably constitute and appoint you as his attorney-in-fact and agent
for the term of this escrow to execute with respect to such Shares all documents
necessary or appropriate to make such Shares negotiable and to complete any
transaction herein contemplated. Subject to the provisions of this paragraph 1
and the terms of the Agreement, Holder shall exercise all rights and privileges
of a stockholder of the Company while the Shares are held by you.

      2. Closing of Purchase.
         -------------------

      (a)   Upon any purchase by the Company of any or all of the Shares
            pursuant to the Agreement, the Company shall give to Holder and you
            a written

<PAGE>

            notice specifying the purchase price for such Shares, as determined
            pursuant to the Agreement, and the time for a closing hereunder (the

            Company hereby irrevocably authorize and direct you to close the
            transaction contemplated by such notice in accordance with the terms
            of said notice.

      (b)   At the Closing, you are directed (a) to date the stock assignment
            form or forms necessary for the transfer of such Shares, (b) to fill
            in on such form or forms the number of Shares being transferred, and
            (c) to deliver same, together with the certificate or certificates
            evidencing the Shares to be transferred, to the Company against the
            simultaneous delivery to you of the purchase price for the Shares
            being purchased pursuant to the Agreement.

      3. Withdrawal. The Holder shall have the right to withdraw from this
         ----------
escrow any Shares as to which all Purchase Options (as defined in the Agreement)
have terminated or expired.

      4. Duties of Escrow Agent.
         ----------------------

      (a)   Your duties hereunder may be altered, amended, modified or revoked
            only by a writing signed by all of the parties hereto.

      (b)   You shall be obligated only for the performance of such duties as
            are specifically set forth herein and may rely and shall be
            protected in relying or refraining from acting on any instrument
            reasonably believed by you to be genuine and to have been signed or
            presented by the proper party or parties. You shall not be
            personally liable for any act you may do or omit to do hereunder as
            Escrow Agent or as attorney-in-fact of Holder while acting in good
            faith and in the exercise of your own good judgment, and any act
            done or omitted by you pursuant to the advice of your own attorneys
            shall be conclusive evidence of such good faith.

      (c)   You are hereby expressly authorized to disregard any and all
            warnings given by any of the parties hereto or by any other person
            or Company, excepting only orders or process of courts of law, and
            are hereby expressly authorized to comply with and obey orders,
            judgments or decrees of any court. In case you obey or comply with

            liable to any of the parties hereto or to any other person, firm or
            Company by reason of such compliance, notwithstanding any such
            order, judgment or decree being

                                       13

            found to have been entered without jurisdiction.

      (d)   You shall not be liable in any respect on account of the identity,
            authority or rights of the parties executing or delivering or
            purporting to execute or deliver the Agreement or any documents or
            papers deposited or called for hereunder.

      (e)   You shall be entitled to employ such legal counsel and other experts
            as you may deem necessary properly to advise you in connection with
            your obligations hereunder and may rely upon the advice of such
            counsel.

      (f)   Your rights and responsibilities as Escrow Agent hereunder shall
            terminate if (i) you cease to be Treasurer of the Company or (ii)
            you resign by written notice to each party. In the event of a
            termination under clause (i), your successor as Treasurer shall
            become Escrow Agent hereunder; in the event of a termination under
            clause (ii), the Company shall appoint a successor Escrow Agent
            hereunder.

      (g)   If you reasonably require other or further instruments in connection
            with these joint Escrow Instructions or obligations in respect
            hereto, the necessary parties hereto shall join in furnishing such
            instruments.

      (h)   It is understood and agreed that should any dispute arise with
            respect to the delivery and/or ownership or right of possession of
            the securities held by you hereunder, you are authorized and
            directed to retain in your possession without liability to anyone
            all or any part of said securities until such dispute shall have
            been settled either by mutual written agreement of the parties
            concerned or by a final order, decree or judgment of a court of
            competent jurisdiction after the time for appeal has expired and no
            appeal has been perfected, but you shall be under no duty whatsoever
            to institute or defend any such proceedings.

      (i)   These Joint Escrow Instructions set forth your sole duties with
            respect to any and all matters pertinent hereto and no implied
            duties or obligations shall be read into these Joint Escrow
            Instructions against you.

      (j)   The Company shall indemnify you and hold you harmless against any
            and all damages, losses, liabilities, costs, and expenses, including
            attorneys' fees and disbursements, for anything done or omitted to
            be done by you as Escrow Agent in connection with this Agreement or
            the

                                       14

      FOR VALUE RECEIVED, the undersigned, Lawrence A. Genovesi (the
"Borrower"), residing at 36 Egypt Beach Road, Scituate, Massachusetts 02066, by
this demand promissory note (hereinafter the "Note"), absolutely and
unconditionally promises to pay to the order of Network Engines, Inc., a

      The entire unpaid principal (not at the time overdue) of this Note

compounded annually (the "Rate"). Each overdue amount (whether of principal,
interest or otherwise) payable on or in respect of this Note or the indebtedness
evidenced hereby shall (to the extent permitted by applicable law) bear
interest, from the date on which such amount shall have first become due and
payable in accordance with the terms hereof to the date on which such amount
shall be paid to the holder of this Note (whether before or after judgment) at
all times be three percent (3%) above the Rate (the "Default Rate"). The unpaid
interest accrued on each overdue amount in accordance with the foregoing terms
of this paragraph shall become absolutely due and payable by the Borrower to the
holder hereof on demand by the holder of this Note at any time. Interest on each
overdue amount will continue to accrue, as provided by the foregoing terms of
this paragraph, and will (to the extent permitted by applicable law) be
compounded monthly until the obligations of the Borrower in respect of the
payment of such overdue amount shall be discharged (whether before or after
judgment).

      On the earlier to occur of DEMAND, or, if no demand has been made prior
thereto, on November 18, 2004, there shall become absolutely due and payable by
the Borrower hereunder, and the Borrower hereby promises to pay to the holder
hereof without presentment, further demand, protest, notice of protest or any
other formalities of any kind, all of which are hereby expressly and irrevocably
waived by the Borrower, the balance (if any) of the principal hereof then
remaining unpaid, all of the unpaid interest accrued hereon and all (if any)
other amounts payable on or in respect of this Note or the indebtedness
evidenced hereby.

      The Borrower absolutely and unconditionally agrees to reimburse the
Lender, on demand, for all its reasonable out-of-pocket expenses, including but
not limited to (a) the reasonable attorney's fees and disbursements and
disbursements incurred or expended in connection with any amendment hereof, and
(b) all attorneys' fees relating to the enforcement of any obligations under
this Note or the satisfaction of any indebtedness of the Borrower hereunder, or
in connection with any litigation proceeding or dispute hereunder in any way
related to the credit hereunder.

                                       2

      All payments on or in respect of this Note or the indebtedness evidenced
hereby shall be made to the holder of this Note without set-off or counterclaim
and free and clear of and without any deduction of any kind for any taxes,
levies, fees, deductions, withholdings, restrictions or conditions of any
nature.

      The Borrower will have the right to prepay at any time the unpaid
principal of this Note in full or in part without premium or penalty. There
shall become and be absolutely due and payable by the Borrower on the date of
each prepayment of principal of this Note, and the Borrower hereby promises to
pay on the date of each such prepayment of this Note, all of the unpaid interest
accrued to such date on the amount of principal of this Note being prepaid on
such date. Any principal amount prepaid may not be reborrowed.

      Any partial payment of the indebtedness evidenced by this Note shall be
applied by the holder hereof (a) first, to the payment of all of the interest
due and payable on the unpaid principal of this Note at the time of such partial
payment, (b) then, to the payment of all (if any) other amounts (except
principal) due and payable at the time of such partial payment on or in respect
of this Note or the indebtedness evidenced by this Note, and (c) finally, to the
repayment or (as the case may be) the prepayment of the unpaid principal of this
Note due and payable at the time of such partial payment.

      All computations of interest payable as provided in this Note shall be
made by the holder hereof on the basis of the actual number of days elapsed
divided by 360.

      If any sum would, but for the provisions of this paragraph, become due and
payable on or in respect of this Note or the indebtedness evidenced hereby on a
day which is not a business day, then such sum shall become due and payable on
the business day next succeeding the day on which such sum would otherwise have
become due and payable hereunder, and interest payable hereunder to the holder
hereof shall be adjusted by the holder hereof accordingly.

      The failure of the holder of this Note to exercise all or any of its
rights, remedies, powers or privileges hereunder in any instance shall not
constitute a waiver thereof in that or in any other instance.

      The Borrower shall remain fully bound until this Note shall be fully paid;
i.e., for the sake of clarity, the holder hereof is entitled to full recourse
against the Borrower for the principal hereof, all of the interest accrued
hereon and all (if any) other amounts payable on or in respect of this Note or
the indebtedness evidenced hereby.

      The Borrower hereby irrevocably waives notice of acceptance, presentment,
notice of nonpayment, protest, notice of protest, suit and all other conditions
precedent in connection with the delivery, acceptance, collection and/or
enforcement of this Note or any collateral or security therefor. The Borrower
hereby absolutely and irrevocably consents and submits to the jurisdiction of
the Courts of the Commonwealth of Massachusetts and of any Federal Court located
in the said Commonwealth in connection with any actions or proceedings brought
against the Borrower by the holder hereof arising out of or relating to this
Note.

      The Borrower hereby agrees, at the Borrower's own expense, to execute and
deliver, from time to time, any and all further, or other, instruments, and to
perform such acts, as the
