representations, warranties, covenants and agreements contained herein and other
good and valuable consideration, the receipt and sufficiency of which are hereby

A.M. two Business Days after the date on which the last of the conditions set
forth in Article VII shall have been satisfied or waived, or on such other date,
time and place as the parties may mutually agree (the "CLOSING DATE").

            (b) At the Effective Time, the effect of the Merger shall be as
provided in the applicable provisions of the DGCL and the NJBCA. Without
limiting the generality of the foregoing, and subject thereto, at the Effective
Time, all the property, rights, privileges, powers and franchises of the
SeraNova and Acquisition shall vest in the Surviving Corporation, and all debts,
liabilities, obligations, restrictions, disabilities and duties of the SeraNova
and Acquisition shall become the debts, liabilities, obligations, restrictions,
disabilities and duties of the Surviving Corporation.

            1.2 Certificate of Incorporation. The certificate of incorporation
of SeraNova, as in effect immediately prior to the Effective Time, shall be
amended to be comparable to the certificate of incorporation of Acquisition, as
in effect immediately prior to the Effective Time,

and shall be the certificate of incorporation of the Surviving Corporation,
until thereafter amended as provided therein or by applicable law.

            1.3 By-Laws. The by-laws of Acquisition, as in effect immediately
prior to the Effective Time, shall be the by-laws of the Surviving Corporation
until thereafter amended as provided therein or by applicable law.

            1.4 Directors and Officers. From and after the Effective Time, (a)
the directors of Acquisition at the Effective Time shall be the initial
directors of the Surviving Corporation, each shall hold office in accordance
with the certificate of incorporation and by-laws of the Surviving Corporation,
and (b) the officers of Acquisition at the Effective Time shall be the initial
officers of the Surviving Corporation, in each case, until their respective
successors are duly elected or appointed and qualified.

            1.5 Conversion of Securities. At the Effective Time, by virtue of
the Merger and without any action on the part of Acquisition, SeraNova or the
holders of any of the following securities:

            (a) Each issued and outstanding share of common stock of Acquisition
shall be converted into one validly issued, fully paid and nonassessable share
of common stock, no par value per share, of the Surviving Corporation;

            (b) Each share of SeraNova Stock held in the treasury of the
SeraNova and each share of SeraNova Stock owned by Silverline shall be canceled
without any conversion thereof and no payment or distribution shall be made with
respect thereto; and

            (c) Subject to the provisions of Sections 1.6 and 2.3, each share of
SeraNova Common Stock issued and outstanding immediately prior to the Effective
Time (other than shares canceled in accordance with Section 1.5(b)) shall be
converted into 0.35 (such number as adjusted in accordance with Section 1.6, the
"COMMON STOCK EXCHANGE RATIO", "EXCHANGE RATIO" or "EXCHANGE RATIOS") of a
validly issued, fully paid and nonassessable American depository share of
Silverline ("SILVERLINE ADS"). As of the Effective Time, each share of SeraNova
Common Stock shall no longer be outstanding and shall automatically be canceled
and retired, and each holder of a certificate representing any shares of
SeraNova Common Stock shall cease to have any rights with respect thereto other
than (i) the right to receive Silverline ADSs to be issued in consideration
therefor upon the surrender of such certificate, (ii) any dividends and other
distributions in accordance with Section 2.2 and (iii) any cash, without
interest, to be paid in lieu of any fractional share of Silverline ADS in
accordance with Section 2.3. The SeraNova Preferred Stock shall be dealt with in
accordance with its certificate of designation.

            1.6 Adjustment of the Exchange Ratios. In the event that, prior to
the Effective Time, any stock split, combination, reclassification or stock
dividend with respect to Silverline ADSs, any change or conversion of Silverline
ADSs into other securities or any other dividend or distribution with respect to
Silverline ADSs (other than regular dividends) should

                                       4
<PAGE>   5

occur or, if a record date with respect to any of the foregoing should occur,
appropriate and proportionate adjustments shall be made to the Exchange Ratio,
and thereafter all references to an Exchange Ratio shall be deemed to be to such
Exchange Ratio as so adjusted.

            1.7 Dissenting Shares. (a) Notwithstanding any provision of this
Agreement to the contrary, shares of SeraNova Common Stock that are outstanding
immediately prior to the Effective Time and which are held by stockholders who
shall not have voted in favor of the Merger, or consented thereto in writing,
and who shall have demanded properly in writing and are entitled to appraisal
for such shares in accordance with Section 14A:11-1 of the NJBCA (collectively,
the "DISSENTING SHARES") shall not be converted into or represent the right to
receive the consideration set forth in Section 1.5(c). Such stockholders (the
"DISSENTERS") shall be entitled to receive such consideration as is determined
to be due with respect to such Dissenting Shares in accordance with the
provisions of Section 14A:11-1, except that all Dissenting Shares held by
stockholders who shall have failed to perfect, or who effectively shall have
withdrawn or lost their rights to appraisal of such shares under Section
14A:11-1 shall thereupon be deemed to have been converted into and to have
become exchangeable for, as of the Effective Time, the right to receive the
Silverline ADSs specified in Section 1.5(c), without any interest thereon, upon
surrender, in the manner provided in Section 2.2 of the Certificate or
Certificates that were formerly evidenced by such Dissenting Shares.

            (b) SeraNova shall give Silverline (i) prompt notice of any demands
for appraisal received by SeraNova, withdrawals of such demands, and any other
instruments served pursuant to Section 14A:11-1 of the NJBCA and received by
SeraNova and (ii) the opportunity to direct all negotiations and proceedings
with respect to demands for appraisal under Section 14A:11-1 of the NJBCA .
SeraNova shall not, except with the prior written consent of Silverline, make
any payment with respect to any demands for appraisal or offer to settle or
settle any such demands.

            1.8 Contribution of Surviving Corporation's Stock. Immediately
following the Merger, Silverline will contribute the stock of the Surviving
Corporation capital of STI (the "SILVERLINE STOCK CONTRIBUTION"). As a result of
the Silverline Stock Contribution, the Surviving Corporation shall become a
wholly-owned subsidiary of STI.

                                   ARTICLE II

                              EXCHANGE OF CERTIFICATES

            2.1 Exchange Agent. Prior to the Effective Time, Silverline shall
appoint a commercial bank or trust company reasonably satisfactory to SeraNova
to act as exchange agent hereunder for the purpose of exchanging Certificates
for Silverline ADSs (the "EXCHANGE AGENT").

            2.2 Exchange Procedures; Distributions with Respect to Unexchanged
Shares; Stock Transfer Books. (a) As of the Effective Time, Silverline shall
deposit with the Exchange

                                       5
<PAGE>   6

Agent, for the benefit of the holders of shares of SeraNova Common Stock
certificates representing such number of Silverline ADSs as may be issuable
pursuant to Sections 1.5(c) in exchange for the shares of SeraNova Common Stock
assuming an exchange of 100% of SeraNova Common Stock less shares of SeraNova
Common Stock held by the Dissenters. Such shares of Silverline ADSs deposited
with the Exchange Agent, together with any dividends or distributions with
respect thereto pursuant to Sections 2.3 and 2.2(c), are referred to herein as
the "EXCHANGE FUND".

            (b) As soon as practicable after the Effective Time, Silverline
shall use its reasonable best efforts to cause the Exchange Agent to send to
each Person who was, at the Effective Time, a holder of record of certificates
which represented outstanding SeraNova Common Stock (the "CERTIFICATES"), which
shares were converted into the right to receive Silverline ADSs pursuant to
Section 1.5(c), a letter of transmittal which (i) shall specify that delivery
shall be effected and risk of loss and title to such Certificates shall pass,
only upon actual delivery thereof to the Exchange Agent and (ii) shall contain
instructions for use in effecting the surrender of the Certificates. Upon
surrender to the Exchange Agent of Certificates for cancellation, together with
such letter of transmittal duly executed and such other documents as the
Exchange Agent may reasonably require, such holder shall be entitled to receive
in exchange therefor (A) a certificate representing the number of whole shares
of Silverline ADSs into which the SeraNova Common Stock represented by the
surrendered Certificate shall have been converted at the Effective Time, (B)
cash in lieu of any fractional share of Silverline ADSs in accordance with
Section 2.3 and (C) dividends and distributions, if any, that are payable in
accordance with Section 2.2(c), and the Certificates so surrendered shall then
be canceled. Subject to Section 2.3 and Section 2.2(c), until surrendered as
contemplated by this Section 2.2(b), each Certificate as applicable, from and
after the Effective Time shall be deemed to represent only the right to receive,
upon such surrender, the number of Silverline ADSs into which such SeraNova
Common Stock shall have been converted.

            (c) No dividends or other distributions declared or made after the
Effective Time with respect to the Silverline ADSs with a record date after the
Effective Time shall be paid to any holder entitled by reason of the Merger to
receive certificates representing Silverline ADSs and no cash payment in lieu of
a fractional share of Silverline ADS shall be paid to any such holder pursuant
to Section 2.3 until such holder shall have surrendered its Certificates
pursuant to this Section 2.2. Subject to applicable law, following surrender of
any such Certificate such holder shall be paid, in each case, without interest,
(i) the amount of any dividends or other distributions theretofore paid with
respect to Silverline ADSs represented by the certificate received by such
holder and having a record date on or after the Effective Time and a payment
date prior to such surrender and (ii) at the appropriate payment date, or as
promptly as practicable thereafter, the amount of any dividends or other
distributions payable with respect to such Silverline ADSs and having a record
date on or after the Effective Time but prior to such surrender and a payment
date on or after such surrender.

            (d) If any certificate representing Silverline ADSs, or any cash, is
to be issued or paid to any Person other than the registered holder of the
Certificate surrendered in exchange

                                       6
<PAGE>   7

therefor, it shall be a condition to such exchange that such surrendered
Certificate shall be properly endorsed and otherwise in proper form for transfer
and such Person either (i) shall pay to the Exchange Agent any transfer or other
taxes required as a result of the issuance of such certificates of Silverline
ADSs and the distribution of such cash payment to such Person, or (ii) shall
establish to the satisfaction of the Exchange Agent that such tax has been paid
or is not applicable. Silverline or the Exchange Agent shall be entitled to
deduct and withhold from the consideration otherwise payable pursuant to this
Agreement to any holder of shares of SeraNova Stock such amounts as Silverline
or the Exchange Agent is required to deduct and withhold with respect to the
making of such payment under the Code, or any provision of state, local or
foreign tax law. To the extent that amounts are so withheld by Silverline or the
Exchange Agent, such withheld amounts shall be treated for all purposes of this
Agreement as having been paid to the holder of the shares of SeraNova Common
Stock in respect of which such deduction and withholding was made by Silverline
or the Exchange Agent. All amounts in respect of taxes received or withheld by
Silverline shall be disposed of by Silverline in accordance with the Code or
such state, local or foreign tax law, as applicable.

            (e) If any Certificate shall have been lost, stolen or destroyed,
upon the making of an affidavit of that fact by the Person claiming such
Certificate to be lost, stolen or destroyed, and subject to such other
conditions as the board of directors of the Surviving Corporation may impose,
the Exchange Agent shall issue in exchange for such lost, stolen or destroyed
Certificate Silverline ADSs as determined under Section 1.5(c) and pay any cash,
dividends or other distributions as determined in accordance with Sections 2.3
and 2.2(c) in respect of such Certificate; provided, that, Silverline may, in
its reasonable discretion and as a condition precedent to the issuance thereof,
require the owner of such lost, stolen or destroyed Certificate to deliver a
bond in such sum as it may reasonably require as indemnity against any claim
that may be made against Silverline, the Surviving Corporation or the Exchange
Agent with respect to the Certificate alleged to have been lost, stolen or
destroyed.

            (f) At the close of business on the day on which the Effective Time
occurs, the stock transfer books of the SeraNova shall be closed and thereafter
there shall be no further registration of transfers of shares of SeraNova Common
Stock on the records of the SeraNova. From and after the Effective Time, the
holders of shares of SeraNova Common Stock outstanding immediately prior to the
Effective Time shall cease to have any rights with respect to such shares except
as otherwise provided herein or by applicable law.

            2.3 No Fractional Shares. No certificates or scrip representing
fractional Silverline ADSs shall be issued upon the surrender for exchange of
Certificates as applicable, and such fractional Silverline ADS shall not entitle
the record or beneficial owner thereof to vote or to any other rights as a
holder of Silverline ADS. In lieu of receiving any such fractional Silverline
ADS, the stockholder shall receive cash (without interest) in an amount rounded
to the nearest whole cent, determined by multiplying (i) the per ADS closing
price on the New York Stock Exchange, Inc. (the "NYSE") of Silverline ADS (as
reported on the NYSE Composite Transactions Tape as such tape is reported in the
Wall Street Journal or another recognized business publication) on the date
immediately preceding the date on which the Effective Time


                                       7
<PAGE>   8

shall occur (or, if the Silverline ADS did not trade on the NYSE on such prior
date, the last day of trading in Silverline ADS on the NYSE prior to the
Effective Time) by (ii) the fraction of the ADS to which such holder would
otherwise be entitled. Silverline shall make available to the Exchange Agent the
cash necessary for this purpose.

            2.4 Return of Exchange Fund. Any portion of the Exchange Fund which
remains undistributed to the former holders of SeraNova Common Stock, as
applicable, for six months after the Effective Time shall be delivered to
Silverline, upon its request, and any such former holders who have not
theretofore surrendered to the Exchange Agent their Certificates in compliance
herewith shall thereafter look only to Silverline for payment of their claim of
Silverline ADSs, any cash in lieu of fractional Silverline ADS and any dividends
or distributions with respect to such Silverline ADSs, and Silverline agrees to
promptly pay any such bonafide claims. None of Silverline, the Exchange Agent or
the SeraNova shall be liable to any former holder of SeraNova Common Stock for
any such Silverline ADSs held in the Exchange Fund (and any cash, dividends and
distributions payable in respect thereof) which are delivered to a public
official pursuant to an official request under any applicable abandoned
property, escheat or similar law.

            2.5 No Further Ownership Rights in SeraNova Capital Stock. All
certificates representing Silverline ADSs delivered upon the surrender for
exchange of any Certificate in accordance with the terms hereof (including any
cash paid pursuant to Section 2.3 or Section 2.2) shall be deemed to have been
delivered (and paid) in full satisfaction of all rights pertaining to the
SeraNova Common Stock previously represented by such Certificate.

            2.6 Further Assurances. If at any time after the Effective Time the
Surviving Corporation shall consider or be advised that any deeds, bills of
sale, assignments or assurances or any other acts or things are necessary,
desirable or proper (a) to vest, perfect or confirm, of record or otherwise, in
the Surviving Corporation, its right, title or interest in, to or under any of
the rights, privileges, powers, franchises, properties or assets of either
SeraNova or Acquisition or (b) otherwise to carry out the purposes of this
Agreement, the Surviving Corporation and its proper officers and directors or
their designees shall be authorized to execute and deliver, in the name and on
behalf of either the SeraNova or Acquisition, all such deeds, bills of sale,
assignments and assurances and do, in the name and on behalf of the SeraNova or
Acquisition, all such other acts and things necessary, desirable or proper to
vest, perfect or confirm its right, title or interest in, to or under any of the
rights, privileges, powers, franchises, properties or assets of the SeraNova or
Acquisition, as applicable, and otherwise to carry out the purposes of this
Agreement.

            3.1 Corporate Organization. (a) SeraNova is a corporation duly
organized, validly existing and in good standing under the laws of the state of
New Jersey. SeraNova has the corporate power and authority to own or lease all
of its properties and assets and to carry on its business as it is now being
conducted, and is duly licensed or qualified to do business in each jurisdiction
in which the nature of the business conducted by it or the character or location
of the properties and assets owned or leased by it makes such licensing or
qualification necessary, except where the failure to be so licensed or qualified
would not have a Material Adverse Effect on SeraNova. As used in this Agreement,
the term "MATERIAL ADVERSE EFFECT" means, with respect to Silverline or
SeraNova, as the case may be, a material adverse effect on (i) the business,
operations, results of operations or financial condition of such party and its
material Subsidiaries or (ii) the ability of such party to consummate the
transactions contemplated hereby. As used in this Agreement, the word
"SUBSIDIARY" means any corporation, partnership, limited liability company,
joint venture or other legal entity of which Silverline or SeraNova, as the case
may be (either alone or through or together with any other Subsidiary), (i)
owns, directly or indirectly, 50% or more of the stock or other equity interests
the holders of which are generally entitled to vote for the election of the
board of directors or other governing body of such corporation, partnership,
limited liability company, joint venture or other legal entity, (ii) is a
general partner, trustee or other entity or person performing similar functions
or (iii) has control (as defined in Rule 405 under the Securities Act of 1933,
as amended (together with the rules and regulations promulgated thereunder, the
"SECURITIES ACT")). True and complete copies of the certificate of incorporation
and by-laws of SeraNova, as in effect as of the date of this Agreement, have
previously been made available by SeraNova to Silverline.

            (b) Each SeraNova Subsidiary (i) is duly organized and validly
existing under the laws of its jurisdiction of organization, (ii) is duly
qualified to do business and in good standing in all jurisdictions (whether
federal, state, local or foreign) where its ownership or leasing of property or
the conduct of its business requires it to be so qualified and in which the
failure to be so qualified would have a Material Adverse Effect on SeraNova and
(iii) has all requisite corporate power and authority to own or lease its
properties and assets and to carry on its business as now conducted.

            (c) The minute books of SeraNova accurately reflect in all material
respects all corporate meetings and actions held or taken since the
incorporation of SeraNova by, or of, its stockholders and board of directors
(including committees of the board of directors of SeraNova).

            3.2 Capitalization. (a) The authorized capital stock of SeraNova

"SERANOVA PREFERRED STOCK" and together with SeraNova Common Stock, "SERANOVA
STOCK"), of which, as of the date hereof, 800 shares were designated, issued and
outstanding. All of the issued and outstanding shares of SeraNova Stock have
been duly authorized and validly issued and are fully paid, nonassessable and
free of preemptive rights, with no personal liability attaching to the ownership
thereof. As of the date of this Agreement, except pursuant to the terms of
options issued pursuant to the SeraNova Stock Option Plan and other employee
options ("SERANOVA STOCK OPTIONS") and warrants for 310,000 shares of SeraNova
Common Stock, SeraNova and its Subsidiaries do not have, and are not bound by,
any outstanding subscriptions, options, warrants, calls, commitments or
agreements of any character calling for the purchase or issuance of any shares
of SeraNova Stock, or any other securities of SeraNova or its subsidiaries, or
any securities representing the right to purchase or otherwise receive any
shares of SeraNova Stock or any of its Subsidiaries. As of the date of this
Agreement, no shares of SeraNova Stock are reserved for issuance, except for
5,691,752 shares of SeraNova Stock reserved for issuance upon exercise of
SeraNova Stock Options. Since July 6, 2000, SeraNova has not issued any shares
of its capital stock or any securities convertible into, or exercisable for, any
shares of its capital stock, other than pursuant to the exercise of employee
stock options granted prior to such date and SeraNova Preferred Stock. Assuming
compliance by Silverline with the terms of this Agreement, after the Effective
Time, there will not be any outstanding subscriptions, options, warrants, calls,
commitments or agreements of any character by which SeraNova or any of its
Subsidiaries, or their respective successors, will be bound calling for the
purchase or issuance of any shares of the capital stock of SeraNova. Section
3.2(a) of the SeraNova Disclosure Schedule sets forth a list of the option
holders, the date of each option to purchase SeraNova Stock granted, the number
of shares subject to each such option, the expiration date of each such option,
and the price at which each such option may be exercised under the SeraNova
Stock Option Plan.

            (b) SeraNova owns, directly or indirectly, all of the issued and
outstanding shares of capital stock or other equity ownership interests of each
of the SeraNova Subsidiaries, free and clear of any Liens and all of such shares
or equity ownership interests are duly authorized and validly issued and are
fully paid, nonassessable and free of preemptive rights, with no personal
liability attaching to the ownership thereof. No SeraNova Subsidiary has or is
bound by any outstanding subscriptions, options, warrants, calls, commitments or
agreements of any character calling for the purchase or issuance of any shares
of capital stock, or any other equity security of such Subsidiary, or any
securities representing the right to purchase or otherwise receive any shares of
capital stock, or any other equity security, of such Subsidiary.

            3.3 Authority; No Violation. (a) SeraNova has full corporate power

cancellation of any of the SeraNova Permits is pending or, to the Knowledge of
SeraNova, threatened, except where the suspension or cancellation of any of the

reasonably be likely to have a Material Adverse Effect on SeraNova. Neither

Material Adverse Effect on SeraNova. Except as disclosed in Schedule 3.7 of the
SeraNova Disclosure Schedule, and except for contracts or agreements entered

to the business, properties, results of operations or condition (financial or

<PAGE>   16


            (b) Each Benefit Plan has been administered in all material respects
in accordance with its terms and the applicable provisions of ERISA and the
Code. SeraNova has received no notice of any investigations by any governmental
agency, termination proceedings or other claims (except claims for benefits
payable in the normal operation of the Benefit Plans), suits or proceedings
against, or involving, any Benefit Plan, or asserting any rights or claims to
benefits under any Benefit Plan that could reasonably give rise to any material
liability, and, to the Knowledge of SeraNova, there are no facts that could
reasonably give rise to any material liability in the event of any such
investigation, claim, suit or proceeding.

            (c) All contributions to, and payments from, the Benefit Plans that
may have been required to be made in accordance with the Benefit Plans have been
timely made. Except as set forth in Schedule 3.11 of the SeraNova Disclosure
Schedule all obligations and liabilities under the Benefit Plans that have
accrued but are not yet due are adequately reflected or reserved for in SeraNova
Financial Statements except those incurred in the ordinary course of business.

            (d) No "prohibited transaction" (as defined in Section 4975 of the
Code or Section 406 of ERISA) has occurred that involves the assets of any
Benefit Plan and that could subject SeraNova or any of its employees, or, to the
Knowledge of SeraNova, a trustee, administrator or other fiduciary of any trusts
created under any Benefit Plan, to any material tax or penalty on prohibited
transactions imposed by Section 4975 of the Code or the sanctions imposed under
Title I of ERISA.

            (e) SeraNova has not contributed, does not contribute, has not been
required to contribute and has not committed to contribute at any time in the
future to any "multiemployer plan" (as defined in Section 4001(a)(3) of ERISA).

Section 302 of ERISA or Section 412 of the Code.

            (f) SeraNova has not taken any action, nor to the Knowledge of
SeraNova has any event occurred, which has resulted in, or will likely result
in, any liability to SeraNova under Title IV of ERISA, including any withdrawal
liability with respect to any multiemployer plan.

            (g) Each Pension Plan intended to be qualified under Section 401(a)
of the Code has received a favorable determination letter from the Internal
Revenue Service, or a timely and proper application letter for such a
determination letter is now pending or will be filed on a timely and proper
manner, as to all of which applications, to the Knowledge of SeraNova, there
exist no reason that a favorable determination letter will not be received, and
to the Knowledge of SeraNova nothing has occurred and no condition exists that
could cause the loss of such qualification.

            (h) Neither SeraNova nor any Subsidiary have any current, contingent
or projected liability in respect of post-employment or post-retirement health,
medical, or life insurance benefits for retired, former, or current employees,
except as required to avoid excise tax under Section 4980B of the Code.


                                       16

            (i)   No payment or other benefit, and no acceleration of the
vesting of any options, payments or other benefits, will, as a direct or
indirect result of the transactions contemplated by this Agreement, be (or
under Section 280G of the Code and the Treasury Regulations thereunder be
presumed to be ) a "parachute payment" to a "disqualified individual" (as those
terms are defined in Section 280G of the Code and the Treasury Regulations
thereunder) with respect to SeraNova or any Subsidiary of SeraNova, without
regard to whether such payment or acceleration is reasonable compensation for
personal services performed, or to be performed, in the future.

            (j)   SeraNova and its material Subsidiaries properly maintain all
Benefit Plans required to be maintained by them under any law, including the
laws of India, except where such failure is not likely to cause a Material
Adverse Effect.

normal business hours, during the period prior to the Effective Time, to all its
properties, books, contracts, commitments and records and, during such period.
Each of Silverline and SeraNova shall, and shall cause its Subsidiaries to,
furnish promptly to the other party consistent with its legal obligations, all
other information concerning its bonuses, properties and personnel as such other
party may reasonably request; provided, however, that each of Silverline and
SeraNova may restrict the foregoing access to the extent that (i) a Governmental
Entity requires either party or any of its Subsidiaries to restrict access to
any properties or information reasonably related to any such contract on the
basis of applicable laws and regulations with respect to national security
matters or (ii) in the reasonable judgment of such party, any law, treaty, rule
or regulation of any Governmental Entity applicable to such party requires it or
its Subsidiaries to restrict access to any properties or information. The
parties will hold any such information in confidence to the extent required by,
and in accordance with, the provisions of the agreements dated October 19, 2000,
between SeraNova and Silverline (collectively the "CONFIDENTIALITY AGREEMENT").
Any investigation by Silverline or SeraNova shall not affect the representations
and warranties of SeraNova or Silverline, as the case may be.

            6.3 Reasonable Best Efforts. (a) Subject to the terms and conditions
of this Agreement, each party hereto will use its reasonable best efforts to (i)
take, or cause to be taken, all actions and to do, or cause to he done, all
things necessary, proper or advisable under applicable laws and regulations to
consummate the Merger and the other transactions contemplated by this Agreement
as soon as practicable after the date hereof and (ii) to obtain and maintain all
approvals, consents, waivers, registrations, permits, authorizations, clearances
and other confirmations, required to be obtained from any third party and/or any
Governmental Entity that are reasonably necessary to consummate the Merger and
the transactions contemplated hereby (each a "REQUIRED APPROVAL"). In
furtherance and not to limitation of the foregoing, each party hereto agrees to
make, as promptly as practicable, to the extent it has not already done so, (i)
an appropriate filing of a Notification and Report Form pursuant to the HSR Act
with respect to the transactions contemplated hereby (which filing shall be made
in any event within five Business Days of the date hereof), (ii) all necessary
filings with other Governmental Entities relating to the Merger, and, in each
case, to supply as promptly as practicable any additional information and
documentary material that may be requested pursuant to such laws and to use
reasonable best effort to cause the expiration or termination of the applicable
waiting periods under the HSR Act and the receipt of Required Approvals under
such other laws as soon as practicable.

            (b) Each of Silverline and SeraNova shall, in connection with the
efforts referenced in Section 6.3(a) to obtain all Required Approvals, use its
reasonable best efforts to (i) cooperate in all respects with each other in
connection with any filing or submission and in connection with any
investigation or other inquiry, including any proceeding initiated by a private
party (ii) promptly inform the other party of any communication received by such
party from, or given by such party to, the Antitrust Division of the Department
of Justice (the "DOJ")

                                       38
<PAGE>   39

or any other Governmental Entity and of any material communication received or
given in connection with any proceeding by a private party, in each case
regarding any of the transactions contemplated hereby, and (iii) permit the
other party to review any communications given by it to, and consult with each
other in advance to the extent practicable of any meeting or conference with,
the DOJ or any such other Governmental Entity or, in connection with any
proceeding by a private party, with any other Person, and to the extent
permitted by the DOJ or such other applicable Governmental Entity or other
Person, give the other party the opportunity to attend and participate in such
meetings and conferences.

            (c) In furtherance and not in limitation of the covenants of the
parties contained in Section 6.3(a) and 6.3(b), if any administrative or
judicial action or proceeding, including any proceeding by a private party, is
instituted (or threatened to be instituted) challenging any transaction
contemplated by this Agreement as violative of any Regulatory Law, or if any
statute, rule, regulation, executive order, decree, injunction or administrative
order is enacted, entered, promulgated or enforced by a Governmental Entity
which would make the Merger, or the transactions contemplated hereby illegal, or
would otherwise prohibit or materially impair or delay the consummation of the
Merger, or the transactions contemplated hereby, each of Silverline and SeraNova
shall cooperate in all respects with each other and use its respective
reasonable best efforts to contest and resist any such action or proceeding and
to have vacated, lifted, overturned any decree, judgment, injunction or other
order, whether temporary, preliminary or permanent, that is to effect and that
prohibits, prevents or restricts consummation of the Merger, or the transactions
contemplated by this Agreement and to have such statue, rule, regulation,
executive order, decree, injunction or administrative order repealed, rescinded
or made inapplicable. Notwithstanding the foregoing or any other provision of
this Agreement, nothing in this Section 6.3 shall limit a party's right to
terminate this Agreement pursuant to Section 8.1(b) or 8.1(c) so long as such
party has up to then complied in all respects with its obligations under this
Section 6.3. For purposes of this Agreement, "REGULATORY LAW" means the HSR Act,
and all other U.S. and Indian Federal, state and foreign, if any, statutes,
rules, regulations, orders, decrees, administrative and judicial doctrines and
other laws that are designed or intended to regulate mergers, acquisitions or
other business combinations.

            (d) SeraNova and its board of directors shall, if any state takeover
statute or similar statute becomes applicable to this Agreement, the Merger or
any other transactions contemplated hereby or thereby, take all action
reasonably necessary to ensure that the Merger and the other transactions
contemplated by this Agreement may be consummated as promptly as practicable on
the terms contemplated hereby or thereby and otherwise to minimize the effect of
such statute or regulation on this Agreement, the Merger and the other
transactions contemplated hereby.

            (e) Silverline and its board of directors shall, if any state
takeover statute for similar statute becomes applicable to this Agreement, the
Merger or any other transactions contemplated hereby, to the extent legally
permissible take all action reasonably necessary to ensure that the Merger and
the other transactions contemplated by this Agreement may be consummated as
promptly as practicable on the terms contemplated hereby and otherwise to


                                       39
<PAGE>   40

minimize the effect of such statue or regulation on this Agreement, the Merger
and the other transactions contemplated hereby.

            6.4 No Solicitation by SeraNova. (a) SeraNova shall not, nor shall
it permit any of its Subsidiaries to, nor shall it authorize or permit any of
its directors, officers or employee, or any investment banker, financial
advisor, attorney, accountant or other representative retained by it or any of
its Subsidiaries to, directly or indirectly through another Person, (i) solicit,
initiate or knowingly encourage (including by way of furnishing information), or
knowingly take any other action to facilitate, the making of any proposal that
constitute, a SeraNova Competing Proposal or (ii) participate in any discussions
or negotiations regarding any SeraNova Competing Proposal; provided, however,
that if, at any time during the period commencing on the 46th day after the date
hereof and ending on the date the Required SeraNova Vote is obtained (the
"SERANOVA APPLICABLE PERIOD"), the board of directors of SeraNova, in the
exercise of its fiduciary duties, determines in good faith, after consultation
with outside counsel, that to do otherwise would not be in the best interests of
SeraNova's stockholders, SeraNova and its representatives may, in response to a
SeraNova Superior Proposal which did not result from a breach of this Section
6.4(a), and subject to providing prior or contemporaneous notice of its decision
to take such action to Silverline, (x) furnish information with respect to
SeraNova and its Subsidiaries to any Person making a SeraNova Superior Proposal
pursuant to a customary confidentiality agreement (as determined by SeraNova
after consultation with its outside counsel) and (y) participate in discussions
or negotiations regarding such SeraNova Superior Proposal. For purposes of this
Agreement, "SERANOVA COMPETING PROPOSAL" means any bona fide proposal or offer
from any Person relating to any direct or indirect acquisition or purchase of
20% or more of the assets of SeraNova and its Subsidiaries, taken as a whole, or
20% or more of the combined voting power of the shares of SeraNova Common Stock,
any tender offer or exchange offer that if consummated would result in any
Person beneficially owning 20 % of more of the combined voting power of the
shares of SeraNova Common Stock, or any merger, consolidation, business
combination, recapitalization, liquidation, dissolution or similar transaction
involving SeraNova or any of its Subsidiaries in which the other party thereto
or its stockholder, will own 20% or more of the combined voting power of the
parent entity resulting from any such transaction, other than the transactions
contemplated by this Agreement. For purpose of this Agreement, a "SERANOVA
SUPERIOR PROPOSAL" means (i) any proposal made by a third party relating to any
direct or indirect acquisition or purchase of 50% or more of the assets of
SeraNova and its Subsidiaries, taken as a whole, or 50% or more of the combined
voting power of the share, of SeraNova Common Stock, any tender offer or
exchange offer that if consummated would result in any Person beneficially
owning 50% or more of the combined voting power of the shares of SeraNova Common
Stock or any merger, consolidation, business combination, recapitalization,
liquidation, dissolution or similar transaction involving SeraNova or any of its
Subsidiaries in which the other party thereto or its stockholders will own 40%
or more of the combined voting power of the parent entity resulting from any
such transaction and (ii) otherwise on terms which the board of directors of
SeraNova determines in its good faith judgment (based on the advice of a
financial advisor of nationally recognized reputation), taking into account the
Person making the proposal and the legal, financial, regulatory and other
aspects of the proposal deemed appropriate by the board of directors of
SeraNova, (x) is reasonably

                                       40
<PAGE>   41

likely to result in a transaction that would be more favorable than the Merger
to SeraNova's stockholders taken as a whole, (y) is reasonably capable of being
completed and (z) for which financing, to the extent required, is then committed
of is reasonably capable of being obtained by such third party.

            (b) Neither the board of directors of SeraNova nor any committee
thereof shall (i) withdraw, or propose publicly to withdraw, in a manner adverse
to Silverline, the approval or recommendation by such board of directors or such
committee of the Merger or this agreement, (ii) subject to Section 6.4(d),
modify, or propose publicly to modify, in a manner adverse to Silverline, the
approval or recommendation by such board of directors or such committee of the
Merger or this Agreement, (iii) approve or recommend, or propose publicly to
approve or recommend, any SeraNova Competing Proposal or (iv) approve or
recommend, or propose to approve or recommend, or execute or enter into, any
letter of intent, agreement in principle, merger agreement, acquisition
agreement, option agreement or other similar agreement or propose publicly or
agree to do any of the foregoing (each, a "SERANOVA ACQUISITION AGREEMENT")
related to any SeraNova Competing Proposal. Notwithstanding the foregoing,
during the SeraNova Applicable Period, in response to a SeraNova Superior
Proposal which would be more favorable than the Merger to SeraNova's
Stockholders taken as a whole and which did not result from a breach of Section
6.4(a), if the board of directors of SeraNova, in the exercise of its fiduciary
duties, determines in good faith, after consultation with outside counsel, that
to do otherwise would not be in the best interests of SeraNova's stockholders,
the board of directors of SeraNova may (x) modify or propose publicly to modify,
in a manner adverse to Silverline, the approval or recommendation of the Merger
or this Agreement by the board of directors of SeraNova and/or (y) terminate
this Agreement (and concurrently with or after such termination, if it so
chooses, cause SeraNova to enter into any SeraNova Acquisition Agreement with
respect to any SeraNova Superior Proposal), but, in the case of clause (y), only
at a time that is during the SeraNova Applicable Period and is after the tenth
day (or the tenth day after a material amendment, in the case of a material
amendment to a SeraNova Superior Proposal) following Silverline's receipt of
written notice advising Silverline that the board of directors of SeraNova is
prepared to accept a SeraNova Superior Proposal (or any material amendment
thereto), specifying the material terms and conditions of such SeraNova Superior
Proposal (or any material amendment thereto) and identifying the Person making
such SeraNova Superior Proposal (or any material amendment thereto) provided
Silverline does not during such period offer a proposal that meets or is
superior to the SeraNova Superior Proposal.

            (c) In addition to the obligations of SeraNova set forth in
paragraphs (a) and (b) of this Section 5.4, SeraNova shall promptly advise
Silverline of any SeraNova Competing Proposal or any inquiry or request for
information relating thereto, the material terms and conditions of such request
or SeraNova Competing Proposal and the identity of the Person making such
request or SeraNova Competing Proposal. SeraNova will promptly keep Silverline
reasonably informed of the status (including amendments) of any such request or
SeraNova Competing Proposal.


                                       41
<PAGE>   42

            (d) Nothing contained in this Section 6.4 shall prohibit SeraNova
from taking and disclosing to its stockholders a position contemplated by Rule
14d-9 or 14e-2 promulgated under the Exchange Act or from making any disclosure
to SeraNova's stockholders if, in the good faith judgment of the board of
directors of SeraNova, after consultation with outside counsel, failure so to
disclose would be inconsistent with its obligations under applicable law;
provided, however, that, subject to Section 6.4(b), neither SeraNova nor its
board of directors, nor any committee thereof shall withdraw, or propose
publicly to withdraw, its position with respect to this Agreement or the Merger
or approve or recommend, or propose publicly to approve or recommend, a SeraNova
Competing Proposal.

            6.5 SeraNova Stock Options. (a) As soon as practicable following the
date of this Agreement, the board of directors of SeraNova (or, if appropriate,
any committee administering the SeraNova Stock Option Plan) shall adopt such
resolutions or take such other actions as may be required to effect the
following:

            (i) adjust the terms of all outstanding SeraNova Stock Options
issued under SeraNova Stock Option Plan and seek amendment to SeraNova's other
option agreements (each, as so adjusted, an "ADJUSTED OPTION"), whether vested
or unvested, as necessary to provide that, at the Effective Time, each SeraNova
Stock Option outstanding immediately prior to the Effective Time shall be
amended and converted, on the same terms and conditions as were applicable under
such SeraNova Stock Option, as follows (the "OPTION ADJUSTMENT"):

            (A) each such SeraNova Stock Option to acquire shares of SeraNova
Common Stock will be converted into an option to acquire the number of
Silverline ADSs determined by multiplying the number of shares of SeraNova
Common Stock subject to such SeraNova Stock Option by the Common Stock Exchange
Ratio (rounded up to the nearest whole share) at an exercise price determined by
dividing the exercise price set forth in such SeraNova Stock Option by the
Common Exchange Ratio (rounded up to the nearest whole cent); and

            (B) make such other changes to the SeraNova Stock Option Plans as
Silverline and SeraNova may agree are appropriate to give effect to the Merger.

            (b) The adjustments provided in this Section 6.5 with respect to any
SeraNova Stock Options to which Section 421(a) of the Code applies shall be and
are intended to be effected in a manner which is consistent with Section 424(a)
of the Code notwithstanding any other provision in this Section 6.5.

            (c) Prior to the Effective Time, Silverline shall take all necessary
actions (including, if required to comply with Section 162(m) of the Code (and
the regulations thereunder) or applicable law or rule of NYSE, obtaining the
approval of its shareholders at the next regularly scheduled annual meeting of
Silverline following the Effective Time) to assume as of the Effective Time all
obligations undertaken by, or on behalf of, SeraNova under Section 6.5(a) and to
adopt at the Effective Time the SeraNova Stock Option Plans and each Adjusted
Option and to take all other action called for in this Section 6.5, including
the reservation,

                                       42
<PAGE>   43

issuance and listing of Silverline Capital Stock in a number at least equal to
the number of shares of Silverline Common Stock that will be subject to the
Adjusted Options.

            (d) As soon as practicable following the Effective Time, Silverline
shall prepare and file with the SEC a registration statement on Form F-8 (or
another appropriate form) registering the Silverline ADSs equal to the number of
shares subject to the Adjusted Options. Such registration statement shall be
kept effective (and the current status of the prospectus or prospectuses
required thereby shall be maintained) at least for so long as any Adjusted
Options or any unsettled awards granted under the SeraNova Stock Option Plan
after the Effective Time may remain outstanding.

            (e) As soon as practicable after the Effective Time, Silverline
shall deliver to the holders of the SeraNova Stock Options appropriate notices
setting forth such holders' rights pursuant to the respective SeraNova Stock
Option Plans and the agreements evidencing the grants of such SeraNova Stock
Options and that such SeraNova Stock Options and agreements shall be assumed by
Silverline and shall continue in effect on the same terms and conditions
(subject to the adjustments required by this Section 6.5 after giving effect to
the Merger).

            (f) Except as otherwise expressly provided in this Section 6.5 and
except to the extent required under the respective terms of the SeraNova Stock
Options, all restrictions or limitations on transfer and vesting with respect to
the SeraNova Stock Options awarded under the SeraNova Stock Option Plan or any
other plan, program or arrangement of SeraNova or any of its Subsidiaries, to
the extent that such restrictions or limitations shall not have already lapsed,
and all other terms thereof, shall remain in full force and effect with respect
to such options after giving effect to the Merger and the assumption by
Silverline as set forth above.

            6.6 Employee Matters. (a) During the one-year period following the
Effective Time (the "TRANSITION PERIOD"), Silverline shall maintain employee
benefit plans, programs and policies for the employee of SeraNova and its
Subsidiaries which, in the aggregate, are substantially comparable to the
employee benefit plan, programs and policies provided by SeraNova and its
Subsidiaries before the Effective Time (other than SeraNova's Employees Stock
Purchase Plan). Furthermore, no employee of SeraNova or a Subsidiary of SeraNova
shall have his or her base hourly rate of pay, base salary or bonus opportunity
reduced during the Transition Period except to the extent such reduction is
called for as a result of a violation of Silverline's generally applicable
policies or a failure to satisfy Silverline's generally applicable performance
standards for similarly situated Silverline employees. The participant accounts
in each unfunded plan, program or policy of SeraNova and each Subsidiary of
SeraNova which are designed to track the performance of SeraNova Stock but which
only pay benefits in cash shall be converted at the Effective Time to accounts
which track the performance of the corresponding Silverline Stock based upon the
principles set forth in this Agreement for converting SeraNova Stock to
Silverline Stock except that there shall he no rounding up or down as part of
such conversions.


                                       43
<PAGE>   44

            (b) During the one-year period following the Transition Period, the
employees of SeraNova and each Subsidiary of SeraNova shall be eligible to
participate in employee benefit plans, programs and policies which, in the
aggregate, are substantially comparable to the employee benefit plans, programs
and policies maintained by Silverline for similarly situated employees.

            (c) Each employee of SeraNova and each Subsidiary of SeraNova shall
receive full credit under each applicable Silverline plan, program or policy for
his or her service as an employee of SeraNova and any Subsidiary of SeraNova on
the same basis that he or she would have received such credit if such service
had been completed as an employee of Silverline for purposes of satisfying any
service requirement to participate in such plan, program or policy (including
any plan, program or policy which provides post-retirement medical benefits) and
any service requirement to receive a non-forfeitable interest in the benefit,
under such plan, program or policy and any service requirement to become
eligible for any early requirement benefit under any pension plans maintained.
Furthermore, if any such Silverline plan, program or policy has any active
employment requirements, pre-existing condition requirements, co-pay,
coinsurance or deductible requirements in effect for a year and an employee of
SeraNova or a Subsidiary of SeraNova had satisfied (or had made payments towards
satisfying) such requirements for a part of such year as a participant in a
SeraNova plan, program or policy, such employee shall receive full credit for
satisfying (or for payments made towards satisfying) such requirements in the
Silverline plan, program or policy for such year when he or she begins to
participate in such plan, program or policy and any such co-pay, coinsurance or
deductible requirements for such year under the Silverline plan, program or
policy shall be no greater than the co-pay, coinsurance or deductible
requirement under the SeraNova plan, program or policy for such year.

            6.7 Fees and Expenses. (a) Whether or not the Merger is consummated,
all Expenses, including fees paid to attorneys, accountants and investment
bankers, incurred in connection with this Agreement and the transactions
contemplated hereby shall be paid by the party incurring such Expenses, except
Expenses (excluding attorneys fees, accountants fees and investment bankers
fees), incurred in connection with the filing, printing and mailing of the Form
F-4 and the Joint Proxy Statement/Prospectus (including SEC filing fees) and the
filing fees for the premerger notification and report forms under the HSR Act,
which shall be shared equally by Silverline and SeraNova. As used in this
Agreement, "EXPENSES" includes all out-of-pocket expenses (including all fees
and expenses of counsel, accountants, investment bankers, experts and
consultant, to a party hereto and its affiliates) incurred by a party or on its
behalf in connection with or related to the authorization, preparation,
negotiation, execution and performance of this Agreement and the transactions
contemplated hereby, including the preparation, printing, filing and mailing of
the Form F-4 and the Joint Proxy Statement/Prospectus and the solicitation of
stockholder approvals and all other matters related to the transactions
contemplated hereby.

            (b) If (1) prior to the date the Required SeraNova Vote is obtained,
a SeraNova Competing Proposal shall have been made to SeraNova or any of its
Subsidiaries, or shall have been made directly to the stockholders of SeraNova
generally, or any Person shall

                                       44
<PAGE>   45

have publicly announced an intention (whether or not conditional) to make a
SeraNova Competing Proposal and thereafter this Agreement is terminated by
either Silverline or SeraNova pursuant to Section 8.1(b), without a SeraNova
Stockholders Meeting having occurred, or 8.l(d)(i) or (2) this Agreement is
terminated by SeraNova pursuant to Section 8.1(e), then SeraNova shall promptly,
but in no event later than the date of such termination, pay Silverline a fee
equal to $4.00 million (the "TERMINATION FEE"), payable by wire transfer of same
day funds; provided, however, that no Termination Fee shall be payable to
Silverline pursuant to clause (1) or (2) of this paragraph (b) unless and until
within 12 months of such termination SeraNova or any of its Subsidiaries enters
into any SeraNova Acquisition Agreement with respect to, or approves or
consummates, any SeraNova Competing Proposal (for the purposes of the foregoing
proviso the term "SERANOVA COMPETING PROPOSAL" shall mean a SeraNova Superior
Proposal pursuant to clause (i) without giving effect to clause (ii)) of the
definition thereof in Section 6.4(a) in which event the Termination Fee shall be
payable under the first to occur of such events. SeraNova acknowledges that the
agreements contained in this Section 6.7(b) are an integral part of the
transactions contemplated by the Agreement, and that, without these agreements,
Silverline would not enter into this Agreement; accordingly, if SeraNova fails
promptly to pay the amount due pursuant to this Section 6.7(b), and, in order to
obtain such payment, Silverline commences a suit which results in a judgment
against SeraNova for the fee set forth in this Section 6.7(b), SeraNova shall
pay to Silverline its costs and expenses (including attorneys' fees and
expenses) in connection with such suit, together with interest on the amount of
the fee at the prime rate of Citibank, N.A. in effect on the date such payment
was required to be made.

            6.8 Public Announcements. SeraNova and Silverline shall use all
reasonable efforts to develop a joint communications plan and each party shall
use all reasonable efforts (i) to ensure that all press releases and other
public statements with respect to the transactions contemplated hereby shall be
consistent with such joint communications plan, and (ii) unless otherwise
required by applicable law or by obligations pursuant to any listing agreement
with or rules of any securities exchange, to consult with each other before
issuing any press release or otherwise making any public statement with respect
to this Agreement or the transactions contemplated hereby.

            6.9 Listing. Silverline shall use its reasonable best efforts to
cause the Silverline ADSs to be issued in the Merger to be approved for
quotation on NYSE, subject to official notice of issuance.

            6.10 Affiliate Letter. On or prior to the date of the SeraNova
Stockholders Meeting, SeraNova will deliver to Silverline a letter (the
"SERANOVA AFFILIATE LETTER") identifying all Persons who are, or may be deemed
to be, "AFFILIATES" of SeraNova for purposes of Rule 145 under the Securities
Act ("RULE 145"). On or prior to the Closing Date, SeraNova will use its
reasonable efforts to deliver on behalf of each Person identified as an
"affiliate" in the SeraNova Affiliate Letter a written agreement in connection
with restrictions on affiliates under Rule 145.


                                       45
<PAGE>   46

            6.11 Tax Treatment. Each of Silverline and SeraNova shall use
reasonable efforts to cause the Merger to qualify as a "reorganization" under
the provisions of Section 368 of the Code and to obtain the opinions of counsel
referred to herein, including the execution of the letters of representation
referred to therein updated as necessary. SeraNova and Silverline and their
respective Subsidiaries shall treat the Silverline ADSs (the "SILVERLINE
RELEVANT STOCK") received in the Merger by holders of SeraNova Common Stock as
property permitted to be received under Section 354 of the Code without the
recognition of gain. Each of SeraNova and Silverline covenants and agrees to,
and agrees to cause its affiliates to, vigorously and in good faith defend all
challenges to the treatment of the reorganization as described in this Section
6.11, including any such challenge to the treatment of the Silverline Relevant
Stock as property permitted to be received under Section 354 of the Code without
the recognition of gain. Each of SeraNova and Silverline agrees that if it
becomes aware of any such fact or circumstance that is reasonably likely to
prevent the Merger from qualifying as a reorganization described in Section
368(a) of the Code, including any such fact or circumstance that is reasonably
likely to prevent the Silverline Relevant Stock from being treated as property
permitted to be received under Section 354 of the Code without the recognition
of gain, it will promptly notify the other party in writing.

            6.12  Tax Representations.  (i)  Silverline, the Surviving
Corporation, and their Affiliates will not engage or consent to any
transaction that would, alone or together with other transactions that have
or occurred or reasonably could occur, require the "Five-Percent Transferee
Shareholders" as defined in Treas. Reg. Sec. 1.367(a)-3(c)(5)(ii) and as
identified by SeraNova, to recognize gain under the gain recognition
agreements required pursuant to Treas. Reg. Sec. 1.367(a)-8 (assuming
compliance by such shareholders with paragraph (g)(2) of such regulation).
Silverline agrees to give written notice to the Five-Percent Transferee
Shareholders of any transaction that would require the recognition of gain
with respect to the Merger pursuant to Trans. Reg. Sec. 1.367(a)-8 (without
assuming compliance this paragraph (g)(2)).  Silverline agrees to supply all
information required for the Five-Percent Transferee Shareholders to comply
with their obligations under Treas. Reg. Sec. 1.367(a)-8 with respect to the
Merger.

            (ii) For the taxable years in which the Merger occurs, Silverline
shall prepare the income tax returns of the Surviving Corporation, including the
information statement required by Treas. Reg. Section 1.367(a)-3(c)(6) (the
"INFORMATION STATEMENT"). The Five-Percent Transferee Shareholders shall have
the right to review Information Statement and receive drafts thereof at least 5
days prior to its due date. Fees for preparing the Information Statement shall
be borne by the Surviving Corporation; however, any costs associated with the
Five-Percent Transferee Shareholders review shall be borne by the Five-Percent
Transferee Shareholders.

            6.13 Supplemental Disclosure Schedule Information. On or prior to
November 17, 2000, SeraNova may deliver to Silverline in accordance with Section
10.7 hereof a revised and supplemental SeraNova Disclosure Schedule containing
additional information gathered and summarized by SeraNova (the "SUPPLEMENTAL
DISCLOSURE SCHEDULE"). SeraNova will provide Silverline and its advisors prompt
access to all documents and other information necessary for Silverline to
analyze the newly disclosed information contained in the Supplemental Disclosure

                                       46
<PAGE>   47


Schedule. Unless Silverline gives SeraNova written notice (a "SCHEDULE
TERMINATION NOTICE") within 15 Business Days after it receives the Supplemental
Disclosure Schedule stating that the newly disclosed information contained in
the Supplemental Disclosure Schedule constitutes a Material Adverse Effect
concerning SeraNova and stating its intention to termination this Agreement as a
result of such determination, the Supplemental Disclosure Schedule shall be
