                           STOCK PURCHASE AGREEMENT

     This Agreement is entered into as of May 11, 2000 by and among ePresence,
Inc., a Massachusetts corporation (the "Buyer"), Strategic Network Designs,
Inc., a New Jersey corporation ("SND") and the stockholders of SND listed on
Schedule I attached hereto (individually, a "Stockholder" and collectively, the
"Stockholders"). The Buyer, SND and the Stockholders are referred to
collectively herein as the "Parties."

                             PRELIMINARY STATEMENT
                             ---------------------

     1.  The Stockholders collectively own all of the outstanding shares of the
capital stock of SND, which consists of 1,000,000 shares of Series A common
stock and 155,380 shares of Series B common stock (collectively, the "SND
Shares"), as set forth in more detail on Schedule I attached hereto.

     2. The Buyer desires to purchase from the Stockholders, and the
Stockholders desire to sell to the Buyer all of the SND Shares, for the
consideration set forth below, subject to the terms and conditions of this
Agreement.

     NOW, THEREFORE, in consideration of the representations, warranties and
covenants herein contained and other good and valuable consideration, the
receipt of which is hereby acknowledged, and with the intent to be bound, the
Parties agree as follows:

                                   ARTICLE I

                      PURCHASE AND SALE OF THE SND SHARES

     1.1 Purchase of the SND Shares from the Stockholders. Upon and subject to
the terms and conditions of this Agreement, at the closing of the purchase and
sale of the SND Shares contemplated by this Agreement (the "Closing"), each
Stockholder shall sell, transfer, convey, assign and deliver to the Buyer, and
the Buyer shall purchase, acquire and accept from each Stockholder, all of the
SND Shares owned by such Stockholder, as set forth on Schedule I attached
hereto.

     1.2 Purchase Price. The purchase price to be paid by the Buyer for the SND
Shares shall be as follows:

     (a)  At the Closing, the Buyer shall deliver:

          (i) To the Stockholders, the sum of Fourteen Million Seven Hundred
Fifteen Thousand One Hundred Eighty Six ($14,715,186) Dollars (the "Cash
Purchase Price"), by wire transfer of immediately available funds to the
designated accounts of each of the Stockholders or by check delivered to the
Stockholders' Representative (net of applicable withholding taxes and
professional fees described on Schedule I attached hereto), in accordance with
the percentages as set forth on Schedule I, attached hereto. Buyer shall
simultaneously

                                      -v-
<PAGE>

remit to SND by wire transfer to an account designated by SND the applicable
withholding taxes described on Schedule I attached hereto.

          (ii) (A) to SND a payment of Nine Hundred Ten Thousand Eight Hundred
($910,800) Dollars to be applied to the built in gain tax imposed under Section
1374 of the Code (the "Built-in Gain Tax") in accordance with Section 5.6
hereof.
               (B) to SND a payment of Three Hundred Seventy Four Thousand
Fourteen ($374,014) Dollars to be applied to the New Jersey Corporate Tax (the
"NJ Tax"), in accordance with Section 5.6 hereof.

          (iii) To the Stockholders, 221,713 shares of common stock (the
"Purchase Price Common Stock"), $0.01 par value per share, of the Buyer (the
"Buyer Common Stock") (representing the quotient of Three Million ($3,000,000)
Dollars divided by the average last reported sales price of the Buyer Common
Stock on the Nasdaq National Market during the ten (10) trading days ending two
(2) days prior to the Closing Date), allocated among the Stockholders as set
forth on Schedule I attached hereto.

          (iv) To State Street Bank and Trust Company, as escrow agent (the
"Escrow Agent"), the sum of One Million Five Hundred Thousand ($1,500,000)
Dollars, (the "Escrow Amount") to be held in an interest-bearing escrow account
pursuant to the terms of the Escrow Agreement attached hereto as Exhibit A (the
"Escrow Agreement"), for the purpose of securing the indemnification obligations
of the Stockholders set forth in Article VI of this Agreement and satisfying any
purchase price adjustment as set forth in Section 1.3(d) of this Agreement. The
Escrow Amount shall be held and disbursed solely for the purposes and in
accordance with the terms of the Escrow Agreement.

      (b) (i) If certain Consulting Revenue Targets (as defined below) and Gross
Margin Targets (as defined below) (collectively, the "Performance Based
Targets") as set forth on Schedule II attached hereto are achieved by the SND
Business Unit (as defined below), the Buyer shall pay to the Stockholders
additional consideration of up to Ten Million ($10,000,000) Dollars pursuant to
Section 1.2(b)(ii) in either cash (the "Contingent Cash Payment") or, in the
sole discretion of the Buyer, subject to the exceptions provided herein, a
combination of cash and shares of Buyer Common Stock (such shares, if any, the
"Contingent Shares") (the Contingent Cash Payment and Contingent Shares
together, the "Contingent Payment"), provided that the aggregate value of the
Contingent Shares issued may not be greater than sixty percent (60%) of the
total Contingent Payment (the "Contingent Shares Limit").  The number of
Contingent Shares to be issued, if any, shall be determined by (i) the Buyer
establishing the dollar value of that portion of the Contingent Payment to be
satisfied by the issuance of Contingent Shares (subject to the Contingent Share
Limit) and (ii) dividing that dollar value by the average last reported sales
price of the Buyer Common Stock on the Nasdaq National Market during the ten
(10) trading days prior to the Contingent Payment Date (as defined in Subsection
(ii) below).  If the Buyer's common stock is not listed on the Nasdaq National
Market or the New York Stock Exchange and the Contingent Shares are not eligible
to be traded thereon, notwithstanding anything to the contrary provided herein,
the Buyer shall pay the Contingent Payment in cash.  Any Contingent Payment made
pursuant to this Section 1.2(b)
<PAGE>

shall be allocated among the Stockholders according to the percentages set forth
on Schedule I attached hereto.

          (ii) Not later than thirty days from the first anniversary of the
Closing Date (the "Contingent Payment Date"), the Buyer shall deliver to the
Stockholders' Representative the Buyer's calculation of the Contingent Payment,
including the number of Contingent Shares to be issued, if any, as part of the
Contingent Payment, accompanied by an income statement for the Earnout Period
(as defined in Schedule II attached hereto) supporting such calculation
(together the "Contingent Payment Report") and Buyer shall pay such amount
immediately. The Buyer shall provide to such Stockholders' Representative
information and, if applicable, access to Buyer's representatives, as may be
reasonably required by him to verify the Contingent Payment Report. In the event
that the Stockholders' Representative shall give written notice to the Buyer
within thirty (30) days after receiving the Contingent Payment Report and the
Contingent Payment that the Stockholders' Representative objects to the Buyer's
determination of the amount paid as the Contingent Payment, the Buyer and
Stockholders' Representative shall engage (and each of the Buyer, on the one
hand, and the Stockholders, jointly and severally on the other hand, shall pay
one-half of the expense of such engagement) a "big five" accounting firm that is
mutually acceptable to the Buyer and the Stockholders' Representative to
determine whether any additional Contingent Payment is due. Prior to engaging
such accounting firm, the Buyer and the Stockholders Representative shall use
reasonable best efforts during a period not to exceed thirty (30) days to
resolve the disputes over the calculation of the Contingent Payment. In the
absence of fraud, the determination of such "big five" accounting firm shall be
final and -

          (iii) binding on all parties. If no notice is provided by the
Stockholders' Representative within such 30-day period, the Contingent Payment
Report delivered by the Buyer shall be the final determination of the Contingent
Payment. For the avoidance of doubt and in order to assist the parties in the
calculation of the Contingent Payment amount, the Parties have attached as
Schedule IV to this Agreement the calculation of each of SND's Consulting
Revenue and Gross Margin for the year ended December 31, 1999. Buyer and the
Stockholders acknowledge and agree that the calculation of SND's Consulting
Revenue and Gross Margin during the Earnout Period (as defined in Schedule II
attached hereto) shall be calculated in the same manner and on the same basis
consistent with the practice and the methodology used in calculating such
amounts for the period ended December 31, 1999. The additional Contingent
Payment, if any, shall be made not later than fifteen (15) days after the final
determination of the Contingent Payment.

          (iv) If there shall occur any reorganization, recapitalization,
consolidation, Change of Control, merger or sale involving the Buyer in which
the Buyer Common Stock is converted into or exchanged for securities, cash or
other property, then, following any such reorganization, recapitalization,
consolidation, merger or sale, the Buyer shall be required to satisfy the
Contingent Payment, if any, solely in cash.

          (c) Notwithstanding anything in this Agreement to the contrary, the
Maximum Contingent Payment shall be deemed earned and (except as set forth in
(iv) below) it shall be immediately paid solely in cash upon the occurrence of
any of the following events or circumstances during the Earnout Period (as
defined in Schedule II attached hereto):
<PAGE>

          (i) the Buyer ceases to directly or indirectly own a majority of the
capital stock of SND;

          (ii) the liquidation of dissolution of Buyer;

          (iii) the Bankruptcy of Buyer; or

          (iv) if either Ranjan Sinha or David R. Rovner is terminated by the
Buyer without cause or if there is a material change in either of their duties
or responsibilities or in their positions as SND Business Unit General Manager
and Vice President of ePresence Solutions unless otherwise mutually agreed
(provided that upon such event the Contingent Payment need not be paid solely in
cash).

      (d) For purposes of this Agreement and all ancillary agreements and
documents related to this transaction, the following terms shall have the
following definitions:

Each of the Stockholders, by execution of this Agreement, hereby irrevocably
appoints the Stockholders' Representative as the agent, proxy and attorney-in-

     1.3  Adjustments Following Closing.

          (a) As promptly as possible following the Closing Date, SND shall
cause Amper, Politziner & Mattia P.A. (the "SND Accountants") to conduct an
audit of the books and records of SND as of the business day immediately
preceding the Closing Date. Not later than sixty (60) days after the Closing
Date, SND shall cause the SND Accountants to deliver an audited balance sheet of
SND as of such date (the "Initial Final Closing Balance Sheet") to the Buyer and
its accountants. The Initial Final Closing Balance Sheet shall be prepared in
accordance with generally accepted accounting principles applied consistently
with SND's past practice and be accompanied by an unqualified opinion of the SND
Accountants.

          (b) The Initial Final Closing Balance Sheet shall be binding upon the
Buyer and the Stockholders, unless the Buyer gives written notice to the
Stockholders' Representative, within forty-five (45) days after receipt of the
Initial Final Closing Balance Sheet, of disagreement with any of the values or
amounts shown on the Initial Final Closing Balance Sheet, specifying as to each
such item in reasonable detail, the nature and extent of such disagreement (the
"Dispute Notice"). If the Buyer and the Stockholders' Representative are unable
to resolve any such disagreement within forty-five (45) days after the date of
the Dispute Notice, the disagreement shall be submitted to arbitration with a
mutually agreed-upon "big five" independent certified public accounting firm
serving as arbitrator. Any decision of the arbitrator shall be binding on all
parties absent fraud. If as a result of the resolution of any dispute by
agreement or by arbitration pursuant to this Section 1.3, any amount shown in
the Initial Final Closing Balance Sheet is determined to be erroneous, such
erroneous amount shall be deleted from the Initial Final Closing Balance Sheet
and the correct amount shall be inserted in lieu thereof. The Initial Final
Closing Balance Sheet, as so corrected, shall constitute the final closing
balance sheet (the "Final Closing Balance Sheet") for purposes of this
Agreement.

          (c) The Buyer, on the one hand, and the Stockholders, jointly and
severally on the other hand, shall each pay one-half of the fees and
disbursements of the SND Accountants and the arbitrator contemplated by Section
1.3(b).

          (d) Based on the Final Closing Balance Sheet, to the extent SND's
Working Capital (as defined below) at the Closing Date is less than zero, the
Cash Purchase Price paid by the Buyer for the purchase of SND Shares shall be
reduced by that amount. For purposes of this Agreement, "Working Capital" means
total current assets (including unbilled accounts receivable), less total
current liabilities (but excluding payments for (i) the estimated Built-in Gains
Tax, (ii) the NJ Tax and (iii) withholding taxes set forth on Schedule I
attached hereto). In the event the adjustment provided in the foregoing sentence
results in a reduction in the purchase price under Section 1.2(a) paid by the
Buyer, the Stockholders' Representative shall pay to the Buyer on behalf of the
Stockholders, in cash, by wire transfer of immediately available funds to an
account designated by the Buyer, the amount by which the purchase price is so
reduced within fourteen (14) days of (i) the expiration of the forty-five (45)
day period after receipt of the Initial Final
<PAGE>

Closing Balance Sheet, within which the Buyer must provide the Dispute Notice,
if any, or (ii) the final resolution of any dispute in connection with the
determination of the Final Closing Balance Sheet, and the Stockholders shall
promptly reimburse the Stockholders' Representative for such amount in
proportion to the percentages set forth on Schedule I attached hereto. To the
extent that any Stockholder does not timely satisfy its allocated portion of
such obligation, the Buyer in its sole discretion may elect to satisfy such
payment obligation from either or both, as the need may be, the Escrow Amount
and through offset against the Contingent Payments as permitted herein.

     1.4  The Closing.

          (a) The execution and delivery by the Parties of this Agreement shall
take place simultaneously with the Closing. The Closing shall take place at the
offices of Hale and Dorr LLP in Boston, Massachusetts, commencing at 9:00 a.m.,
local time, on May 11, 2000, or, if all of the conditions to the obligations of
the Parties to consummate the transactions contemplated hereby have not been
satisfied or waived by such date, on such mutually agreeable later date as soon
as practicable after the satisfaction or waiver of all conditions to the
obligations of the Parties to consummate the transactions contemplated hereby
(the "Closing Date").

all long-term debt; and

               (xiv)  Buyer shall deliver the Escrow Amount to the Escrow Agent.

     1.5 Further Assurances. At any time and from time to time after the
Closing, at the reasonable request of the Buyer and without further
consideration, the Stockholders shall promptly execute and deliver such
instruments of sale, transfer, conveyance, assignment and confirmation, and take
all such other action as the Buyer may reasonably request, more effectively to
transfer, convey and assign to the Buyer, and to confirm the Buyer's title to,
all of the SND Shares, to put the Buyer through its ownership of the SND Shares
in actual possession and operating control of the assets (including without
limitation the original corporate minute books of SND and all corporate seals),
properties and business of SND, and to carry out the purpose and intent of this
Agreement.

the Contingent Shares, if any, (collectively, the "Purchase Price Securities"),

account for investment only, and not with a view to, or for sale in connection
with, any distribution of such shares in violation of the Securities Act of
1933, as amended (the "Securities Act"), or any rule or regulation under the
Securities Act.

          (b) Such Stockholder has had adequate opportunity to obtain from

registered under the Securities Act or an exemption from registration is then
available.

          (e) Such Stockholder agrees and understands that until the Purchase
Price Securities are sold under an effective registration statement pursuant to
Article VIII or sold pursuant to Rule 144 under the Securities Act, a legend
substantially in the following form may be placed on the certificate

<PAGE>

          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."

Shares are duly authorized, validly issued, fully paid and nonassessable and
were issued without violation of any preemptive rights. There are no outstanding
or authorized options, warrants, rights, agreements, obligations or commitments
to which SND is a party or which are binding upon SND providing for the

Property will be owned or available for use by SND on identical terms and
conditions immediately following the Closing. SND has taken all reasonable
measures to protect the proprietary nature of each item of SND Intellectual
Property, and to maintain in confidence all trade secrets and confidential

foregoing.

          (b) None of the activities or business presently or previously
conducted by SND infringes or violates, or constitutes a misappropriation of,
any Intellectual Property rights of any other person or entity. Neither SND nor
any Stockholder has received any complaint, claim or notice alleging any such
infringement, violation or misappropriation.
<PAGE>

          (c) Section 3.8(c) of the Disclosure Schedule is a true, correct and
complete list of each license or other agreement pursuant to which SND has
licensed, distributed or otherwise granted any rights to any third party with
respect to, any of SND Intellectual Property. SND has not agreed to indemnify
any person or entity for or against any infringement, misappropriation, or other
conflict with respect to any item of Intellectual Property that SND owns or
uses.

products, software or other items currently offered for sale or license, under
development or previously sold or licensed by SND, and with respect to which any

liability, are Year 2000 Compliant. For purposes of this Agreement, "Year 2000
Compliant" means, with respect to computer and electronic systems, that such

any leasing or brokerage commission upon the renewal of any Lease. No
construction, alteration or other leasehold improvement work with respect to any
of the Leases remains to be paid for or to be performed by SND. The financial

                                   ARTICLE V

                     POST CLOSING COVENANTS AND AGREEMENTS

     5.1 SND Stock Options. At the Closing Date, each issued and outstanding
stock option to acquire any shares of the capital stock of SND, whether or not
then exercisable ("SND Stock Option"), shall be deemed cancelled and substituted
with an option (a "Buyer Option") to acquire shares of Buyer Common Stock, as
set forth in the applicable SND resolution of its board of directors provided to
Buyer. Such cancellation and substitution shall comply in all respects with and
shall be performed in accordance with the methodology prescribed by the
provisions of Section 424(a) of the Internal Revenue Code of 1986, as amended,
and the regulations thereunder, and each Buyer Option shall provide the option
holder with the rights and benefits that are no less favorable to him than were
provided under the SND Stock Option for which it is substituted. It is intended
that the foregoing cancellation and substitution shall be undertaken in a manner
which will not constitute a "modification" (within the meaning of Section 424 of
the Code and applicable regulations) of any SND Stock Option which constitutes
an incentive stock option within the meaning of Section 422 of the Code.
Notwithstanding the foregoing, the Buyer shall issue 20,000 incentive stock
options to each of David Rovner and Ranjan Sinha under its stock incentive plan,
having a term of ten years, vesting in equal annual increments over three years
and having an exercise price of $10.65 per share (the Closing price of the Buyer
Common Stock as of May 10, 2000).

     5.2 Operation of SND Business. (a) The Buyer will operate SND as a separate
business unit during the Earnout Period (as defined in Schedule II attached
hereto). During such period the SND Business Unit shall continue to be operated
consistently with its historical practices (since January 1, 1999) unless the
Stockholders' Representative and the Buyer's Designee mutually agree otherwise,
and for purposes of determining the amount of the Contingent Payment, account
for Consulting Revenue (as defined in Schedule II) and Cost of Goods Sold (as
defined in Schedule II) as set forth in Schedule II attached hereto.

          (b) Without limiting the provisions of subsection (a) above, Buyer
shall operate SND in good faith so as to facilitate the Stockholders' ability to
maximize the Consulting Revenue and Gross Margin (as defined in Schedule II) of
the SND Business Unit during the Earnout Period. Regarding any contracts and
engagements with annual revenues equal to or greater than One hundred thousand
dollars ($100,000), the Stockholders' Representative in conjunction with Buyer's
designee shall mutually determine such contracts and engagements to enter into
on behalf of the SND Business Unit during the Earnout Period. In the event that
Buyer's designee and the Stockholders' Representative are not able to mutually
agree regarding any such contract or engagement and the SND Business Unit enters
into any such consulting contract or engagement (hereinafter "Other Services
Revenue ") the revenue from such Other Services Revenue shall be included in the
calculation of the Consulting Revenue, and the margin from such Other Services
Revenue shall be included in the calculation of the Gross Margin at fifty-two
percent (52%)for purposes of the determination of the Contingent Payment. To
effectuate this provision, a determination of the expected gross profit margin
for a contract or engagement under Other Services Revenue shall be made by the
Buyer and the Stockholders' Representative and a credit solely for purposes of
the calculation of the Contingent Payment shall be given against Cost of Goods
Sold in an amount equal to the difference between the
<PAGE>

expected gross profit margin and 52% times the Other Services Revenue received
for that contract or engagement. Buyer shall make available to the SND Business
Unit funding for capital expenditures consistent with its business operations.

     5.3 Location of SND Office. During the Earnout Period, Buyer shall maintain
SND's principal office in Clark, New Jersey.

     5.4 Registration of SND Options. Not later than the date any such option
first vests, the Buyer shall file an appropriate post-effective amendment to a
Registration Statement on Form S-8 in order to include within such Registration
Statement the stock option plan of SND in existence at the Closing Date and all
SND Stock Options issued and outstanding under such plan as of the Closing Date.

     5.5 Section 338(h)(10) Election. Each Stockholder and the Buyer will join
in making, and will take any and all action necessary to effect, a timely and
irrevocable election under Section 338(h)(10) of the Code (and the Treasury
Regulations and administrative pronouncements thereunder) and any comparable
provision of state, local, or foreign Tax law (collectively a "Section
338(h)(10) Election"). Each Stockholder and the Buyer shall file all Tax returns
in a manner consistent with the Section 338(h)(10) Election, and will not take
any position contrary thereto. At the Closing, the Stockholders will deliver to
the Buyer two properly executed (by each Stockholder) and completed copies of
Internal Revenue Service Form 8023 with respect to SND (collectively, the "Form
8023") and, as applicable, two properly executed and completed copies of any
analogous forms required pursuant to state, local, or foreign tax law. At least
ten (10) days prior to the Closing Date, the Buyer will provide the
Stockholders' Representative with the information regarding the Buyer necessary
to enable the Stockholders to complete the Form 8023. The Buyer and the
Stockholders' Representative will jointly determine the Line 9/11 Information.
The Stockholders' Representative will provide the Buyer with any information
regarding the Stockholders as is necessary to determine the Line 9/11
Information. The Buyer will provide to the Stockholders' Representative a copy
of the Line 9/11 Information, and shall include the parties allocation of the
Purchase Price, which shall be allocated to the assets of SND for tax purposes
as follows:

              (i) First, among the tangible assets acquired in accordance with
their then fair market value, which the parties agree is the net book value
thereof on the Closing Date; and

              (ii) Next, to "Section 197 Intangibles" (as defined in Section 197
of the Code) other than to a covenant not to compete, which the parties agree
shall have an allocated value of $25,000.

The Buyer shall be responsible for filing the Form 8023.

     5.6  Tax Returns and Cooperation.

          (a) The Stockholders' Representative shall prepare or cause to be
prepared all income Tax returns or reports for SND that must be filed in respect
to any short taxable period ended on or before the Closing Date and each such
Tax return shall be prepared in a manner consistent with SND's past practice.
The Stockholders' Representative shall permit the Buyer to
<PAGE>

review and comment on each such Tax return described in the preceding sentence.
The Buyer shall file or cause to be filed each such Tax return. The Buyer shall
pay or cause to be paid to the appropriate taxing authority any Taxes imposed on
SND in respect of such returns. Pursuant to Section 1.2(a)(ii) and (iii), the
Stockholders have deposited with SND from the proceeds of the Purchase Price,
$910,800 as an estimate of the Built-in Gain Tax and $374,014 as an estimate of
the NJ Tax. If either such tax is greater than the applicable estimate, the
Stockholders shall pay to the Buyer on or before the due date for the tax return
an amount equal to the Built-in Gain Tax in excess of $910,800 or an amount
equal to the NJ Tax in excess of $374,014, as the case may be. If such estimate
is greater than the actual Built-in Gain Tax and/or the NJ Tax, such excess
shall be promptly paid to the Shareholders in proportion to their ownership in
SND as set forth on Schedule I attached hereto. The Stockholders shall pay all
Taxes imposed on them individually as S corporation shareholders pursuant to
Section 1366 of the Code and any analogous provision of state or local law. The
Buyer shall prepare or cause to be prepared and file all other Tax returns
required to be filed after the Closing Date, and shall pay all Taxes shown
thereon or otherwise imposed on or payable by SND after the Closing Date
attributable to the operations of SND following the Closing.

          (b) The Buyer and the Stockholders shall cooperate fully, as and to
the extent reasonably requested by the other party, in connection with the
filing of Tax returns pursuant to this Section 5.2 and any audit, litigation or
other proceeding with respect to Taxes. Such cooperation shall include signing
any Tax return, amended Tax returns, claims or other documents necessary to
settle any Tax controversy, the retention and (upon the other party's request)
the provision of records and information which are reasonably relevant to any
such audit, litigation or other proceeding and making employees available on a
mutually convenient basis to provide additional information and explanation of
any material provided hereunder. Each of the Buyer and the Stockholders agrees
that it will, and, in the case of the Buyer, that it will cause SND to, retain
all books and records with respect to Tax matters pertinent to SND relating to
any taxable period beginning before the Closing Date until the expiration of the
statute of limitations (and, to the extent notified by the other party, any
extensions thereof) of the respective taxable periods, and to abide by all
record retention agreements entered into with any taxing authority.

          (c) The Stockholders shall control any Tax proceeding related to any
pre-Closing period of SND, and the Buyer shall have the right to participate in
any Tax proceeding related to income Taxes for any pre-Closing period of SND
which may have the effect of increasing the Tax liability of the Buyer, SND or
their Affiliates for any Tax period ending after the Closing, and the
Stockholders shall not settle or compromise any such proceeding without the
Buyer's prior written consent, which consent shall not be unreasonably withheld
or delayed.

     5.7  Non-Competition; Non-Solicitation.

          (a) For a period of three (3) years after the Closing Date, David R.
Rovner and Ranjan Sinha, severally but not jointly, covenants and agrees that
such Stockholder will not:

              (i) directly or indirectly engage in any business or enterprise
(whether as owner, partner, officer, director, employee, consultant, investor,
lender or otherwise, except as the holder of not more than 1% of the outstanding
stock of a publicly-held company) that is
<PAGE>

competitive with the Buyer's current business or with SND's current business,
including but not limited to any business or enterprise that develops,
manufactures, markets, or sells any product or service that competes with any
current product or service developed, manufactured, marketed or sold, or planned
to be developed, manufactured, marketed or sold, by the Buyer or SND, or any
subsidiaries of the Buyer or SND;

              (ii) directly or indirectly solicit any Person (as that term is
defined in Section 3(a)(9) of the Securities Exchange Act of 1934, as amended,
and used in Sections 13(d)(3) and 14(d)(2) of such act) that is a Current
Customer (as defined below) of the Buyer or SND for purposes of selling products
or services to such Person that are in competition with the products and
services offered or sold by the Buyer or SND. "Current Customer" shall mean any
Person who utilizes any product or service sold or provided by the Buyer or SND
during such period; any Person who utilized any such product or service within
the previous 12 months;

              (iii) employ, either directly or indirectly, any current employee
of the Buyer or SND, and agrees not to solicit, or contact in any manner that
could reasonably be construed as a solicitation, either directly or indirectly,
any employee of the Buyer or SND for the purpose of encouraging such employee to
leave or terminate his or her employment with the Buyer or SND; or

              (iv) solicit, either directly or indirectly, a current vendor or
supplier of the Buyer or SND for purposes of encouraging such vendor or supplier
to cease or diminish providing products or services to the Buyer or SND, or to
change adversely the terms under which such vendor or supplier provides such
products or services to the Buyer or SND.

          (b) The Stockholders requested by the Buyer prior to Closing shall
enter into a Non-Competition/Non-Solicitation Agreement in the form attached
hereto as Exhibit C.

     5.8 Reformation. If any covenant in Section 5.7 of this Agreement is held
to be unreasonable, arbitrary or against public policy, such covenant will be
considered to be divisible with respect to scope, time, and geographic area, and
such lesser scope, time or geographic area, or all of them, as an arbitrator or
a court or competent jurisdiction may determine to be reasonable, not arbitrary,
and not against public policy, will be effective, binding and enforceable
against the applicable Stockholder.

     5.9 Release of Personal Guarantees. With respect to any cash collateral or
personal guarantees provided by either David Rovner or Ranjan Sinha to secure
any borrowings by SND from First Union disclosed in the Disclosure Schedule,
Buyer shall obtain release of any cash collateral amounts within ten (10)
business days from the Closing Date and the release of any other guarantees
within thirty (30) days from the Closing Date or cause such borrowings to be
repaid in full.

                                  ARTICLE VI

                                INDEMNIFICATION

     6.1  Indemnification by the Stockholders.

<PAGE>

          (a) Each Stockholder shall, subject to the provisions of this Article
VI, jointly and severally (subject to Sections 6.4(b) and 6.7 below), indemnify
the Buyer in respect of, and hold the Buyer harmless against, any and all debts,
obligations and other liabilities, monetary damages, fines, fees, penalties,
interest obligations, deficiencies, losses and expenses (including without
limitation amounts paid in settlement, interest, court costs, costs of third
party investigators, fees and expenses of outside attorneys, accountants,
financial advisors and other third party experts, and other third party expenses
of litigation) (collectively, the "Losses") incurred or suffered by the Buyer or
SND in connection with each and all of the following:

               (i) any misrepresentation or breach of any representation or
warranty made by the Stockholders or SND pursuant to Article III in this
Agreement (including the Disclosure Schedules);

               (ii) any breach of any covenant, obligation or agreement of the
Stockholders or SND contained in this Agreement, provided, however, that any
Losses resulting from a claim relating to a breach by a Stockholder of the
provisions of Section 5.7 shall be recoverable solely as against such breaching
Stockholder;

               (iii) any tax liabilities or obligations of SND relating to
periods ending on or before the Closing Date including any taxes related to the
338(h)(10) election (other than the payments contemplated by Section 1.2(a)(ii)
above);

               (iv) any tax liabilities arising from or related to the change in
SND's status from a C-corporation to an S-corporation; and

               (v) any liabilities or obligations with respect to any past or
present subsidiary of SND.

          (b) Each Stockholder shall severally indemnify the Buyer in respect
of, and hold the Buyer harmless against, any and all Losses incurred or suffered
by the Buyer or SND resulting from, relating to or constituting any
misrepresentation or breach of any representation or warranty made by such
Stockholder pursuant to Article II of this Agreement.

     6.2 Indemnification by the Buyer. The Buyer shall indemnify each
Stockholder in respect of, and hold it harmless against, any and all Losses
incurred or suffered by such Stockholder resulting from:

               (i) any misrepresentation or breach of any representation or
warranty made by the Buyer pursuant to Article IV of this Agreement; and

               (ii) any breach of any covenant, obligation or agreement made by
the Buyer contained in this Agreement.

     6.3  Claims for Indemnification.

          (a) A Party entitled to indemnification under this Article VI (an
"Indemnified Party") shall give prompt written notification (a "Claim Notice")
to the party from whom indemnification is sought (the "Indemnifying Party") of
the claim, and when known, facts
<PAGE>

constituting the basis and the amount of such claim (the "Claimed Amount").
In the event of any such claim for indemnification hereunder resulting from or
in connection with any claim, action, suit or proceeding relating to a third
party, the Claim Notice shall be delivered within twenty (20) days after receipt
of such third party's claim and shall specify, if known, the amount or an
estimate of the amount of the liability arising therefrom. If the Indemnified
Party is seeking to enforce such claim pursuant to the Escrow Agreement, the
Indemnified Party shall deliver a copy of the Claim Notice to the Escrow Agent.
The Indemnified Party shall not settle or compromise any claim by a third party
for which it is entitled to indemnification hereunder without the prior written
consent, which shall not be unreasonably withheld or delayed, of the
Indemnifying Party (in the case of the Stockholders, such consent shall be
provided by in the Stockholders' Representative); provided, however, that if
suit shall have been instituted against the Indemnified Party and the
Indemnifying Party shall not have taken control of such suit after notification
thereof as provided in Section 6.3(b) of this Agreement, the Indemnified Party
shall have the right to settle or compromise such claim upon giving notice to
the Indemnifying Party as provided in Section 6.3(b).

          (b) Defense by the Indemnifying Party. In connection with any claim
which may give rise to indemnity hereunder resulting from or arising out of any
claim or legal proceeding by a person other than the Indemnified Party, the
Indemnifying Party, at the sole cost and expense of such Indemnifying Party,
may, upon written notice to the Indemnified Party, assume the defense of any
such claim or legal proceeding if the Indemnifying Party acknowledges to the
Indemnified Party in writing the obligation of the Indemnifying Party to
indemnify the Indemnified Party with respect to all elements of such claim. If
the Indemnifying Party assumes the defense of any such claim or legal
proceeding, the Indemnifying Party shall select counsel reasonably acceptable to
the Indemnified Party to conduct the defense of such claims or legal proceedings
and at the sole cost and expense of the Indemnifying Party shall take all steps
necessary in the defense or settlement thereof. The Indemnifying Party shall not
consent to a settlement of, or the entry of any judgment arising from, any such
claim or legal proceeding, without the prior written consent of the Indemnified
Party (which consent shall not be unreasonably withheld or delayed). The
Indemnified Party shall be entitled to participate in (but not control) the
defense of any such action, with its own counsel and at its own expense. If the
Indemnifying Party does not assume the defense of any such claim or litigation
resulting therefrom within thirty (30) days after the date such claim is made:
(i) the Indemnified Party may defend against such claim or litigation in such
manner as it may deem appropriate, including, but not limited to, settling such
claim or litigation, after giving notice of the same to the Indemnifying Party,
on such terms as the Indemnified Party may deem appropriate, and (ii) the
Indemnifying Party shall be entitled to participate in (but not control) the
defense of such action, with its counsel and at its own expense. If the
Indemnifying Party thereafter seeks to question the manner in which the
Indemnified Party defended such third party claim or the amount or nature of any
such settlement, the Indemnifying Party shall have the burden to prove by a
preponderance of the evidence that the Indemnified Party did not defend or
settle such third party claim in a reasonably prudent manner.

          (c) Within thirty (30) days after delivery of a Claim Notice, the
Indemnifying Party shall deliver to the Indemnified Party a written response in
which the Indemnifying Party shall either: (i) agree that the Indemnified Party
is entitled to receive all of the Claimed Amount (in which case such response
shall be accompanied by a payment by the Indemnifying Party to
<PAGE>

the Indemnified Party of the Claimed Amount, as provided in Section 6.4;
provided that if the Indemnified Party is seeking to enforce such claim pursuant
to the Escrow Agreement, the Indemnifying Party and the Indemnified Party shall
deliver to the Escrow Agent, within three (3) days following the delivery of the
response, a written notice executed by both parties instructing the Escrow Agent
to distribute to the Buyer the Claimed Amounts), (ii) agree that the Indemnified
Party is entitled to receive part, but not all, of the Claimed Amount (the
"Agreed Amount") (in which case such response shall be accompanied by a payment
by the Indemnifying Party to the Indemnified Party of the Agreed Amount, as
provided in Section 6.4; provided that if the Indemnified Party is seeking to
enforce such claim pursuant to the Escrow Agreement, the Indemnifying Party and
the Indemnified Party shall deliver to the Escrow Agent, within three (3) days
following the delivery of the response, a written notice executed by both
parties instructing the Escrow Agent to distribute to the Buyer the Agreed
Amount), or (iii) contest that the Indemnified Party is entitled to receive any
of the Claimed Amount. If the Indemnifying Party in such response contests the
payment of all or part of the Claimed Amount, the Indemnifying Party and the
Indemnified Party shall use good faith efforts to resolve such dispute. If such
dispute is not resolved within thirty (30) days following the delivery by the
Indemnifying Party of such response, the Indemnifying Party and/or the
Indemnified Party shall each have the right to submit such dispute for
resolution in accordance with the procedures set forth in Article VII of this
Agreement.

          (d) For purposes of this Section 6.3, with respect to the
Stockholders, any references to the Indemnified Party or the Indemnifying Party
(except provisions relating to an obligation upon the Stockholders to make
payments provided for in this Article VI) shall be deemed to refer to the
Stockholders' Representative. The Stockholders' Representative shall have full
power and authority on behalf of each Stockholder to take any and all actions on
behalf of, execute any and all instruments on behalf of, and execute or waive
any and all rights of, the Stockholders under this Article VI. The Stockholders'
Representative shall have no liability to any Stockholder for any action taken
or omitted on behalf of the Stockholders pursuant to this Article VI.

     6.4  Payment of Indemnification Obligations.

          (a) Any amount payable by the Buyer pursuant to this Article VI shall
be effected by a wire transfer of immediately available funds in the amount of
any indemnification liability, on or before the seventh (7) day after the final
resolution, by agreement or otherwise, of the applicable indemnification claim.

          (b) If any claim for indemnification is made by the Buyer under this
Article VI prior to the expiration of the Escrow Period, (i) the Buyer shall
first apply to the Escrow Agent for reimbursement of such claim against the
Escrow Amount in accordance with the provisions of the Escrow Agreement and (ii)
upon final resolution of such indemnity claims, if such indemnity claims are
resolved and fully settled for an amount greater than the amount held in escrow
or offset against Contingent Payments as provided in paragraph 6.4(c) below (the
"Deficit Amount"), David R. Rovner and Ranjan Sinha jointly and severally, and
Stockholders other than David R. Rovner and Ranjan Sinha severally, shall remit
the Deficit Amount in cash to the Stockholders' Representative who shall
immediately transfer such amounts to the Buyer or to an account designated by
the Buyer. Except for payments from the Escrow Amount or offsets
<PAGE>

from Contingent Payments pursuant to (c) below, all indemnification obligations
shall be effected by a wire transfer of immediately available funds on or before
the seventh (7) day after the final resolution by agreement or otherwise.

          (c) Notwithstanding anything set forth in this Agreement to the
contrary, any amounts that the Buyer is entitled to for indemnification from the
Stockholders pursuant to this Article VI may, at the option of the Buyer, be
satisfied by setting off all or any portion of such amount against the
Contingent Payment in the amount necessary to satisfy such claim. Any such set-
off by the Buyer shall be subject to the limits of Section 6.7. If the
Stockholders' Representative disputes the Buyer's right to effect such set-off,
the Buyer shall deposit the set-off amount that is being disputed in an escrow
account established with a bank or other third party institution reasonably
acceptable to the Stockholders' Representative, which funds shall be held by
such escrow agent until the dispute is resolved and which shall be funded first
by offset against the Contingent Shares and to the extent of any excess, against
the Contingent Cash Payment. The parties to this Agreement agree to cooperate
with one another in establishing and selecting an escrow agent to act in such
capacity and any such escrow agreements shall be substantially similar to the
Escrow Agreement executed at Closing.

     6.5  Dollar Limitations.

          (a) The maximum amount payable by the Stockholders under this Article
VI shall be equal to the aggregate amount of cash paid by the Buyer pursuant to
Sections 1.2(a)(i), (ii), (iv) and the Contingent Cash Payment, if any, remitted
by the Buyer to the Stockholders (the "Cap Amount"), except that such maximum
amount shall not be applicable for any claims made for:

               (i) breach of the representations and warranties contained in
Sections 2.1, 2.2 and 2.3;

               (ii) breach of the representations and warranties contained in
Sections 3.1, 3.2 and 3.3; or

               (iii) any fraudulent misrepresentations or fraudulent breach of
any warranty and representation contained in Article II or III hereof.

          (b)  Notwithstanding anything to the contrary herein, the Indemnifying
Stockholders shall not be liable under this Article VI unless and until the
aggregate Losses for which they would otherwise be liable exceeds Two Hundred
Thousand ($200,000) Dollars (at which point the Indemnifying Stockholders shall
become liable for the aggregate Losses, and not just amounts in excess of Two
Hundred Thousand ($200,000) Dollars), provided, however, that this limitation
shall not apply to:

               (i) a claim relating to a breach of the representations and
warranties set forth in Article II or in Sections 3.1, 3.2, 3.3 and 3.15 and
Section 3.13 with respect only to any refund claim under the unsigned Amendment
to the Maintenance and Operational Service Support Agreement between SND and
Bristol Myers Squibb Company dated as of February 1, 1996;
<PAGE>

               (ii) fraud; or

               (iii) a claim pursuant to the indemnity agreements set forth in
Sections 6.1(a)(iii) and (iv).

          (c) No Stockholder shall have any claim or any right of contribution
against, or indemnification from, SND with respect to any breach of any of the
representations, warranties, covenants or agreements relating to SND under this
Agreement (including without limitation a claim based upon a breach of a
representation or warranty made by SND to such Stockholder under any agreement
between SND and such Stockholder).

          (d) Any and all aggregate Losses for which the Indemnifying
Stockholders are responsible under this Article VI shall be reduced on a dollar-
for-dollar basis by any amount received by the Buyer or SND under any issuance
policy, except Losses as a result of fraud.

     6.6 Survival. The representations and warranties of the Stockholders and
the Buyer set forth in this Agreement shall survive the Closing and the
consummation of the transactions contemplated hereby and continue until one year
after the Closing Date; except that (i) the representations and warranties
contained in Article II and Sections 3.1, 3.2, 3.3, 3.4, 4.1, 4.2, 4.3 and 4.4
shall survive the Closing and continue without limitation, (ii) the
representations and warranties contained in Sections 3.15, 3.20 and 3.24, and
the agreements in Sections 6.1(a)(iii) and (iv) shall survive the Closing and
continue until the expiration of the applicable statute of limitations, and
(iii) the representations and warranties contained in Sections 3.8 and 3.16
shall survive the Closing and continue for a period of eighteen months from the
Closing Date. Any claims asserted in writing prior to the expiration of the
representation, warranty or agreement that is the basis for such claim, if any,
as provided in this Article VI, shall survive for purposes of such claim until
such claim is finally resolved and is satisfied in full.

     6.7 Certain Limitations. The liability of Messrs. Sinha and Rovner under
Section 6.1(a) shall be joint and several and the liability of each such
Stockholder shall be limited to their aggregate pro rata portion of the Cap
Amount based on their aggregate stock ownership as set forth on Schedule I, plus
the pro rata portion of the Cap Amount of each of the Stockholders set forth on
Schedule V.  The Stockholders set forth on Schedule V shall have no liability
under Section 6.1(a) and are severally liable under Section 6.1(b) with the
liability of each such Stockholder limited to his or her pro rata portion of the
Cap Amount based on his or her stock ownership as set forth on Schedule I.  The
liability of the Stockholders set forth on Schedule VI shall be several with
respect to Sections 6.1(a) and (b) and shall be limited to his or her pro rata
portion of the Cap Amount based on his or her stock ownership as set forth on
Schedule I.

                              REGISTRATION RIGHTS

     8.1 Registration of Shares. The Buyer shall permit each Stockholder to
include in any registration statement filed by the Buyer with the SEC for an
underwritten public offering of any shares of Buyer Common Stock (other than a
registration statement on Form S-4 or S-8 or any successor form, any Purchase
Price Securities held ("Registrable Shares") (any such registration statement in
which Registrable Shares are included shall be considered a "Registration
Statement"), subject to (i) the right of the Buyer to limit the number of
Registrable Shares to be included in such Registration Statement if the managing
underwriter of such offering determines that the inclusion of such shares in
such offering would adversely affect the marketability of such offering and (ii)
the rights of any other person to whom the Buyer has granted or may in the
future grant registration rights. The Buyer shall provide written notice to the
Stockholders' Representative of its intention to file such a registration
statement, and any holder of Registrable Shares intending to include such shares
in such Registration Statement must so notify the Stockholders' Representative,
who must then so notify the Buyer on behalf of such holders, within ten (10)
days of the date of the Buyer's notice. Any holder of Registrable Shares
included in a registration shall agree to be bound by the underwriting agreement
for such offering and the terms and restrictions relating to such offering, as
required by the underwriters. Notwithstanding the foregoing, the Buyer shall not
be required, pursuant to this Section 8.1, to include any Registrable Shares in
a Registration Statement if such Registrable Shares can then be sold pursuant to
Rule 144 under the Securities Act.

     8.2  Registration Procedures.

          (a) In connection with the filing by the Buyer of a Registration
Statement, the Buyer shall furnish to each Stockholder whose Registrable Shares
are to be included in a Registration Statement pursuant to Section 8.1 (the
"Registering Stockholder") a copy of the prospectus, including a preliminary
prospectus, in conformity with the requirements of the Securities Act.

          (b) If the Buyer has delivered preliminary or final prospectuses to
the Registering Stockholders and after having done so the prospectus is amended
to comply with the requirements of the Securities Act, the Buyer shall promptly
notify the Registering Stockholders and, if requested by the Buyer, the
Registering Stockholders shall immediately cease making offers or sales of
shares under such Registration Statement and return all prospectuses to the
Buyer. The Buyer shall reasonably promptly provide the Registering Stockholders
with revised prospectuses and, following receipt of the revised prospectuses,
the Registering Stockholders shall be free to resume making offers and sales
under such Registration Statement.

          (c) The Buyer shall pay the expenses incurred by it in complying with
its obligations under this Article VIII, including all registration and filing
fees, exchange listing fees, fees and expenses of counsel for the Buyer, and
fees and expenses of accountants for the Buyer, but excluding any selling
commissions or underwriting discounts incurred by the Registering Stockholders
in connection with sales under a Registration Statement and any legal or other
fees of the Registering Stockholders.
<PAGE>

     8.3  Requirements of Registering Stockholders.

          (a) The Buyer shall not be required to include any Registrable Shares
in a Registration Statement unless the Registering Stockholder owning such
shares furnishes to the Buyer in writing such information regarding such
Registering Stockholder and the proposed sale of Registrable Shares by such
Registering Stockholder as the Buyer may reasonably request in writing in
connection with the Registration Statement or as shall be required in connection
therewith by the SEC or any state securities law authorities.

          (b) Each Registering Stockholder agrees:

              (1) to indemnify the Buyer and each of its directors and officers
against, and hold the Buyer and each of its directors and officers harmless
from, any losses, claims, damages, expenses or liabilities (including reasonable
attorneys fees) to which the Buyer or such directors and officers may become
subject by reason of any statement or omission in a Registration Statement made
in reliance upon, or in conformity with, a written statement by such Registering
Stockholder furnished pursuant to this Section 8.3; and

              (2) to report to the Buyer sales made pursuant to a Registration
Statement.

     8.4  Indemnification. The Buyer agrees to indemnify and hold harmless each
Registering Stockholder against any losses, claims, damages, expenses or
liabilities to which such Registering Stockholder may become subject by reason
of any untrue statement of fact contained in a Registration Statement or any
omission to state therein a fact required to be stated therein or necessary to
make the statements therein not misleading, except insofar as such losses,
claims, damages, expenses or liabilities arise out of or are based upon written
information furnished to the Buyer by or on behalf of a Registering Stockholder
for use in such Registration Statement.  The Buyer shall have the right to
assume the defense and settlement of any claim or suit for which the Buyer may
be responsible for indemnification under this Section 8.4.

     8.5 Assignment of Rights. A Registering Stockholder may not assign any of
its rights under this Article VIII except in connection with the transfer of
some or all of his or her Registrable Shares to a child or spouse, or trust for
their or its benefit or to a general or limited partner or member of any
Stockholder that is a partnership or a limited liability company, provided each
such transferee agrees in a written instrument delivered to the Buyer to be
bound by the provisions of this Article VIII.

     8.6 No Conflict with Existing Agreements. The registration rights provided
in this Article VIII are subordinate to the registration rights previously
granted by the Buyer. To the extent any provision of this Article VIII conflicts
or is inconsistent with any registration rights provision in any agreement
previously entered into by the Buyer, the provisions of such previous agreement
shall apply, and the provisions of this agreement shall be deemed to be modified
insofar so as is necessary to not conflict or to be inconsistent with such
previous agreement.

                                  SCHEDULE II
                                  -----------

CONSULTING REVENUE - the sum of (i) all revenues generated and delivered by the
SND Business Unit (exclusive of Product Sale Revenue (as defined below)) less
customer discounts and other deductions and adjusted for provision for bad
debts, all recognized or provided for in accordance with  the SND Business
Unit's applicable accounting policies and practices which are in accordance with
GAAP and have been consistently applied, plus (ii) an amount equal to the value
of the aggregate services by an employee of the SND Business Unit utilized by
Buyer or any affiliate of Buyer on projects as to which the revenues from such
projects are not paid to the SND Business Unit but are paid to Buyer or such
affiliate, less (iii) an amount equal to the value of the aggregate services by
an employee of the Buyer or any affiliate of Buyer on projects as to which the
revenues from such projects are paid to the SND Business Unit.  In addition,
Consulting Revenue denominated in foreign currencies will be translated to U.S.
dollars using weighted average exchange rates in effect during the period of
recognition, in accordance with GAAP.

PRODUCT SALE REVENUE - purchase and resale of third party products.

CONSULTING REVENUE TARGETS - For the twelve consecutive month period commencing
as of the Closing Date and ending on the first anniversary of the Closing Date
(the "Earnout Period"), the minimum Consulting Revenue which the SND Business
Unit must achieve to earn the Minimum Contingent Payment, (assuming the Minimum
Gross Margin Target is also achieved) is Twenty Million ($20,000,000) Dollars
(the "MINIMUM REVENUE TARGET").  The  minimum Consulting Revenue which the SND
Business Unit must achieve during the Earnout Period, to earn the Maximum
Contingent Payment (assuming the Maximum Gross Margin Target is also achieved)
is Twenty Two Million Five Hundred Thousand ($22,500,000) Dollars (the "MAXIMUM
REVENUE TARGET"). No Contingent Payment will be made for Consulting Revenue
generated that is lower than the Minimum Revenue Target.  Any Consulting Revenue
generated that is greater than the Maximum Revenue Target will be eligible to
receive the Contingent Payment, subject to the gross margin requirements set
forth below, up to the Maximum Contingent Payment as determined under the
following formula:

     (achieved Consulting Revenue) - (Maximum Revenue Target) x (achieved Gross
Margin Percentage) x (20%) + (the applicable Contingent Payment derived from the
below Schedule of Contingent Payments for such achieved Gross Margin Percentage
under the Maximum Revenue Target column).

For the avoidance of doubt, (e.g., if the achieved Consulting Revenue was $24.5
million and the achieved Gross Margin on such revenue was 54%, the Contingent
Payment would be $9.02 million as follows:  $24.5 million - $22.5 million x 54%
x 20% + $8.8 million) .

COST OF GOODS SOLD - includes, but is not limited to, all costs associated with
the delivery of consulting services, including direct salaries, direct payroll
taxes, direct employee benefits including 401K, contracted services and billable
travel and reasonable entertainment costs determined in accordance with the SND
Business Unit's applicable accounting policies and
<PAGE>

practices which are in accordance with GAAP and have been consistently applied;
provided, however, that the Cost of Goods Sold shall exclude (i) any
compensation expense relating to the acceleration of the vesting of the Class B
non-voting common stock immediately prior to the Closing Date, and (ii) the
costs of and expenses relating to any new hires agreed to by Buyer for any new
practice group for a period of ninety days.

CONTINGENT PAYMENT - a Contingent Payment will be made, in accordance with the
Schedule below, not later than thirty days after the first anniversary of the
Closing Date for Consulting Revenue generated during the Earnout Period, which
is equal to or greater than Twenty Million ($20,000,000) Dollars and for which
an average Gross Margin is achieved that is equal to or greater than the Minimum
Gross Margin Target.  A Contingent Payment will be made for Consulting Revenue
achieved that is greater than the Maximum Revenue Target, up to the Maximum
Contingent Payment, only if the average Gross Margin achieved is equal to or
greater than the Minimum Gross Margin Target.

GROSS MARGIN - Gross Margin represents Consulting Revenues less Cost of Goods
Sold.

GROSS MARGIN TARGETS -During the Earnout Period, the minimum average Gross
Margin which the SND Business Unit must achieve to earn the Minimum Contingent
Payment, (assuming the Minimum Revenue Target is also achieved) is Fifty Two
Percent (52%) (the "MINIMUM GROSS MARGIN TARGET").  The average Gross Margin
which the SND Business Unit must achieve during the Earnout period, to earn the
Maximum Contingent Payment (assuming the Maximum Revenue Target is also
achieved) is Fifty Seven Percent (57%) (the "MAXIMUM GROSS MARGIN TARGET").  No
Contingent Payment will be made where the Consulting Revenue achieved during the
Earnout Period has an average Gross Margin below the Minimum Gross Margin
Target.  Where the Consulting Revenue achieved during the Earnout Period has an
average Gross Margin that is greater than the Maximum Gross Margin Target, the
Contingent Payment will not exceed the Maximum Contingent Payment.

MAXIMUM CONTINGENT PAYMENT - Ten Million ($10,000,000) Dollars, which may be
earned upon achieving the Maximum Revenue Target and the Maximum Gross Margin
Target, or achieving a Gross Revenue above the Maximum Revenue Target at a Gross
Margin which allows for the Maximum Contingent Payment to be made.  No
Contingent Payment will be made greater than the Maximum Contingent Payment.

MINIMUM CONTINGENT PAYMENT - Four Million ($4,000,000) Dollars, which may be
earned only upon achieving both the Minimum Revenue Target and the Minimum Gross
Margin Target.  No Contingent Payment will be made below the Minimum Contingent
Payment.  (The use of the term "minimum" in  "Minimum Contingent Payment" merely
indicates the smallest Contingent Payment which may be achieved, provided that
the Minimum Revenue Target and the Minimum Gross Margin Target is achieved, and
in no way is a guarantee of receipt by the former stockholders of SND of any
Contingent Payment).

                      ePRESENCE, INC. ACQUIRES SND, INC.

             Acquisition Strengthens e-Services Capabilities with
                 CRM and Wireless Solution Delivery Expertise


WESTBORO, MASS., MAY 15, 2000 - ePresence, Inc. (NASDAQ: BNYN), today announced
the acquisition of SND, Inc., a highly complementary addition to its rapidly
growing e-services business.  SND, a privately owned company located in Clark,
New Jersey, delivers Customer Relationship Management (CRM), eMobility, wireless
and custom application development solutions to Global 2000 companies.  By
combining these capabilities with ePresence's web design, development and
infrastructure services, the company offers an ideal portfolio of Internet-based
solutions for clients seeking to build highly personalized relationships with
their customers, business partners and employees.

The acquisition was completed for total consideration of $30.5 million,
consisting of $17.5 million in cash, 221,713 shares of ePresence common stock
and a one-year earn-out of $10.0 million contingent on performance.  The
acquisition will be accounted for as a purchase.  SND reported revenues of $15.1
million for the twelve months ended March 31, 2000 and $11.6 million in calendar
year 1999, which represented 80 percent growth over 1998 totals.

"SND is our second acquisition in 2000 and demonstrates our commitment and
ability to use our strong asset base to expand our capabilities and rapidly grow
our e-services business," said Bill Ferry, chairman and chief executive officer
of ePresence, Inc.  "I am excited about the new clients and expertise in CRM and
wireless applications that SND brings to ePresence, and we plan to continue
expanding our business through organic growth, acquisitions and strategic
partnerships."

SND will join ePresence Solutions, the company's rapidly growing e-services
division.  With approximately 70 professional staff, SND has extensive
experience in delivering robust CRM, eMobility, and wireless solutions to blue-
chip companies including Johnson & Johnson, Bayer,
<PAGE>

Sodexho Marriott and Bristol-Myers Squibb. The addition of SND's experience and
business partners such as Siebel Systems, Inc., clearly reinforces ePresence's
position as a leader in providing highly personalized, customer-centric Internet
solutions and will complement ePresence Solution's end-to-end service delivery
capability.

"We are very excited about expanding our growth potential by leveraging the vast
resources, worldwide customer relationships and complementary e-service
capabilities of ePresence," said David Rovner, SND's founder and managing
director.  "From web design through infrastructure, SND and ePresence clients
now have access to a full range of e-services that can help them build more
personalized relationships with their customers."
