        (a) On the Closing Date, Purchaser shall pay to Sellers, in immediately
available funds, the sum of (A) $924,185.00, less (B) $250,813.00 (which amount
represents the total of customer deposits and prepayments received by Sellers as
of the Closing Date with respect to the Purchased Contracts as shown on Schedule
1.3) (the sum of (A) and (B) being referred to as the "Closing Portion of the

                                   ARTICLE 2
                            ASSUMPTION OF LIABILITIES

    2.1 Assumption of Assumed Liabilities. Purchaser agrees, effective on the
Closing Date, to assume the Assumed Liabilities and thereafter to pay, perform
and discharge such Assumed Liabilities in full, in accordance with their terms.
Notwithstanding anything contained in this Agreement to the contrary, Purchaser
shall not assume or become liable for any Retained Liability.

    2.2 Assignment of Purchased Contracts.

     (a) Nothing contained in this Agreement shall be construed as an attempt to
agree to assign any Purchased Contract which is non-assignable without the
consent of any other party thereto, unless such consent shall have been given.
Sellers and Purchaser acknowledge and agree that the assignment of certain of
the Purchased Contracts will require the consent of the customer party thereto.
With respect to such Purchased Contracts, each Seller shall use its commercially
reasonable efforts to obtain such consents after the Closing and each Seller
shall take all such commercially reasonable action as shall be necessary or
proper (i) in order to enable Purchaser to realize the full value of every such
Purchased Contract and to preserve for the benefit of Purchaser the rights and
obligations of Sellers under such Purchased Contract, and (ii) to facilitate the
collection of the monies due and payable, or to become due and payable, to
Sellers pursuant to every such Purchased Contract, and Sellers shall remit such
monies to Purchaser within five business days of collection. Purchaser, at its
expense, shall perform all of Sellers' obligations due to be performed under any
such non-assigned Purchased Contract to the extent (i) Purchaser can perform
such obligations without violating the terms of such non-

                                      2
<PAGE>   3
assigned Purchased Contract, and (ii) Purchaser is being provided the benefits
of such non-assigned Purchased Contract.

     (b) If within 90 days after the Closing Date, Sellers are unable to obtain
consents from customers party to Purchased Contracts whose total Maintenance and
Support Revenues that would be due under such Purchased Contracts following the
Closing exceed $198,859, Purchaser will be entitled to deduct from any amounts
due to Sellers pursuant to Section 1.3(b) an amount equal to the product
obtained by multiplying (i) the amount of the total Maintenance and Support
Revenues that would have been due and owing pursuant to such Purchased Contracts
for the balance of the term of each such Purchased Contract (excluding any
renewal terms) but for which Sellers were unable to obtain consents to
assignment, by (ii) 25%. Sellers shall have no liability to Purchaser under this
Section 2.2(b) in the event Sellers are unable to obtain consents from customers
party to Purchased Contracts whose total Maintenance and Support Revenues that
would be due under such Purchased Contracts following the Closing are less than
or equal to $198,859.

     (c) If within 90 days after the Closing Date, Sellers are unable to obtain
consents from customers party to Purchased Contracts whose total Sales Order
Backlog Revenues that would be due under such Purchased Contracts following the
Closing exceed $97,219, Purchaser will be entitled to deduct from any amounts
due to Sellers pursuant to Section 1.3(b) an amount equal to the product
obtained by multiplying (i) the amount of the total Sales Order Backlog Revenues
that would have been due and owing pursuant to such Purchased Contracts for the
balance of the term of each such Purchased Contract (excluding any renewal
terms) but for which Sellers were unable to obtain consents to assignment, by
(ii) 20%. Sellers shall have no liability to Purchaser under this Section 2.2(c)
in the event Sellers are unable to obtain consents from customers party to
Purchased Contracts whose total Sales Order Backlog Revenues that would be due
under such Purchased Contracts following the Closing are less than or equal to
$97,219.

                              SELLERS AND PURCHASER

         5.1 Confidentiality. Each party hereto agrees that, for a period of
five years from and after the date hereof, it will not, and will use reasonable
efforts to ensure that its representatives and Affiliates will not, use in the
conduct of its business (except as contemplated by this Agreement), or disclose
to any other Person, any confidential or non-public information relating to the
other party; provided, however, that the foregoing prohibitions shall not apply
to (i) disclosures that are required by Law, by a Governmental Authority or
pursuant to applicable stock exchange or automated quotation system rules or
regulations; (ii) information that is ascertainable or obtained from public or
published information; (iii) information received from a Third Party not known

or (v) information disclosed to or filed with any Person for the purpose of

                                       6
<PAGE>   7
the provisions of this Section shall not prohibit Purchaser from using or
disclosing such confidential or non-public information that relates to the
Purchased Assets after consummation of the transactions contemplated hereby at
the Closing.

         5.2 Publicity. Neither Purchaser nor Sellers shall make any public
disclosures about the existence or contents of this Agreement or the
negotiations relating to the transactions contemplated hereby or cause to be
publicized in any manner whatsoever by way of interviews, responses to questions
or inquiries, press releases or otherwise any aspect of the transactions
contemplated by this Agreement without prior notice to and approval of the
other, except as may otherwise be required by Law or stock exchange or automated
quotation system rules or regulations.

         5.3 Agreement Not to Solicit Customers. Each Seller acknowledges that
the consideration to be paid to Sellers pursuant to this Agreement reflects the
future value to Purchaser of the business relationships with customers party to
the Purchased Contracts. Each Seller further acknowledges that customers party
to the Purchased Contracts are located throughout the Territory and that the
restrictions contained in this Section are necessary and reasonable to give
Purchaser the full value of the Purchased Contracts which it is purchasing. Each
Seller therefore covenants and agrees with Purchaser that, during the period
commencing on the Closing Date and ending four years thereafter, no Seller nor
any of its Affiliates will, directly or indirectly, on behalf of itself or any
other Person, contact, divert, take away or solicit, for the purpose of
providing Dialer-Based Products thereto in the Territory, any Person which was a
customer receiving Dialer-Based Products from any Seller as of the Closing Date.
Each Seller recognizes that the breach of any of its obligations under this
Section may give rise to irreparable injury to Purchaser inadequately
compensable in damages and that, accordingly, Purchaser may seek injunctive
relief against the breach or threatened breach of this Section, in addition to
any available remedies at law.

         5.4 Sellers' Obligations During the Transition Period. During the
Transition Period, Sellers shall continue to provide all Maintenance and Support
Services to be provided under the Purchased Contracts and shall be entitled to
receive any Maintenance and Support Revenues due under the Purchased Contracts
for Maintenance and Support Services provided during the Transition Period.

         5.5 Post-Closing Assistance. For a period of 45 days after the Closing
Date, Sellers shall provide to Purchaser and its employees and agents reasonable
access to Sellers' employees and agents who are familiar with Sellers'
Dialer-Based products and the customers party to the Purchased Contracts
(including, without limitation, project managers, application developers,
installers and customer service personnel), for purposes of enabling Purchaser
to adequately service and support such customers. Such access shall be provided
during Sellers' normal business hours and without adversely affecting Sellers'
operations. Each Seller acknowledges that the employees and agents of Purchaser
who will be given access to Sellers' employees and agents for purposes of this
Section 5.5 will acquire information and knowledge that is valuable to the
Purchaser in providing Dialer-Based Products to its customers. Accordingly, each
Seller

                                       7
<PAGE>   8
covenants and agrees that it shall not, during the period commencing on the
Closing Date and ending on the first anniversary of the Closing Date, directly
or indirectly, solicit or recruit any employee or agent of Purchaser who has
contact with any employee or agent of Sellers for purposes of this Section 5.5;
provided, however, that general employment advertisements and recruiter calls
not specifically targeted to Purchaser shall not be considered solicitation for
employment so long as no follow-up is pursued when any Seller learns that any
prospect is such an employee or agent of Purchaser. Purchaser covenants and
agrees that it shall not, during the period commencing on the Closing Date and
ending on the first anniversary of the Closing Date, directly or indirectly,
solicit or recruit any employee or agent of Sellers whose primary
responsibilities are not related to Dialer-Based Products; provided, however,
that general employment advertisements and recruiter calls not specifically
targeted to any Seller shall not be considered solicitation for employment so
long as no follow-up is pursued when Purchaser learns that any prospect is such
an employee or agent of any Seller.

         5.6 Access; Dispute Resolution. Purchaser shall provide Sellers access
to Purchaser's books and records, during Purchaser's normal business hours and
upon reasonable notice to Purchaser, for purposes of Sellers verifying the
amounts due to Sellers pursuant to Section 1.3 and the amounts owed to Purchaser
pursuant to Section 2.2. If Sellers disagree with any amount paid to Sellers
pursuant to Section 1.3, or any amount Purchaser claims is owed to Purchaser
pursuant to Section 2.2, Sellers shall notify Purchaser of such disagreement
within 20 days after the receipt of such payment or notice of payment due, as
applicable, specifying in detail the reasons for such disagreement and providing
Sellers' calculation of the amount of such payment Sellers believe is due. If,
within 30 days after the receipt by Purchaser of Sellers' notice of
disagreement, Purchaser and Sellers are unable to agree upon the amount of such
payment, then Sellers and Purchaser shall jointly select an independent public
accounting firm, and such independent accounting firm shall determine the amount
of such payment due within 30 days of the submission of the issue to such
independent accounting firm. If it is necessary to engage such an independent
accounting firm, the cost thereof shall be borne equally by the parties. In the
event that Sellers and Purchaser are unable to agree, within ten days after such
30-day period, as to who shall serve as such independent accounting firm, then
either Purchaser or Sellers shall be authorized to ask the Atlanta office of the
American Arbitration Association to appoint an independent accounting firm so to
determine the amount of any such payment. Any determination made by any
independent accounting firm selected pursuant to this Section 5.6 shall be
final, conclusive and binding upon the parties hereto.

         5.7 Expenses. Each party hereto will pay its own expenses (including
attorney's fees), except as may be otherwise provided herein.

         5.8 Further Assurances. At any time and from time to time after the
Closing, (i) each Seller shall, at the request of Purchaser, take any and all
actions necessary to fulfill its obligations hereunder and to put Purchaser in
actual possession and operating control of the Purchased Assets, and (ii)
Sellers and Purchaser shall execute and deliver such further instruments of
conveyance, sale, transfer and assignment, and take such other actions as may be
necessary or appropriate to effectuate, record or perfect the transfer of the
Purchased Assets to

                                       8

or otherwise to effectuate and consummate any of the transactions contemplated
hereby.

                                       10
<PAGE>   11
entitled to indemnification by the Indemnifying Party to the extent that the
Indemnifying Party is unable to establish that it has been prejudiced by such
late receipt of the Claims Notice; provided, however, that the Indemnified Party
shall not be entitled to indemnification unless the Claims Notice is delivered
to the Indemnifying Party prior to compromise or payment of any Asserted
Liability by the Indemnified Party.

         8.5 Opportunity to Contest. The Indemnifying Party may elect to
compromise or contest, at its own expense and with counsel of its choice
reasonably acceptable to the Indemnified Party, any Asserted Liability. If the
Indemnifying Party elects to compromise or contest such Asserted Liability, it
shall, within 30 days (or sooner, if the nature of the Asserted Liability so
requires), notify the Indemnified Party of its intent to do so by sending a
notice to the Indemnified Party (the "Contest Notice"), and the Indemnified
Party shall cooperate, at the expense of the Indemnifying Party, in the
compromise or contest of such Asserted Liability. If the Indemnifying Party
elects not to compromise or contest the Asserted Liability, fails to notify the
Indemnified Party of its election as herein provided or contests its obligation
to indemnify under this Agreement, the Indemnified Party (upon further notice to
the Indemnifying Party) shall have the right to pay, compromise or contest such
Asserted Liability on behalf of and for the account and risk of the Indemnifying
Party. Anything in this Section 8.5 to the contrary notwithstanding, the
Indemnifying Party shall not, without the Indemnified Party's written consent,
settle or compromise any Asserted Liability or consent to entry of any judgment
which does not include an unconditional term releasing the Indemnified Party
from all Liability in respect of such Asserted Liability. In any event, the
Indemnified Party and the Indemnifying Party may participate, at their own
expense, in the contest of such Asserted Liability. Sellers and Purchaser shall
cooperate fully with each other as to all Asserted Liabilities, shall make
available to each other as reasonably requested all information, records, and
documents relating to all Asserted Liabilities and shall preserve all such
information, records, and documents until the termination of any Asserted
Liability. Sellers and Purchaser also shall make available to each other, as
reasonably requested, their personnel, agents, and other representatives who are
responsible for preparing or maintaining information, records, or other
documents, or who may have particular knowledge with respect to any Asserted
Liability.

         8.6 Subrogation Rights. In the event that the Indemnifying Party shall
be obligated to indemnify the Indemnified Party pursuant to this Article 8, the
Indemnifying Party shall upon payment of such indemnity in full, be subrogated
to all rights of the Indemnified Party with respect to the Loss to which such
indemnification relates; provided, however, that the Indemnifying Party shall
only be subrogated to the extent of any amount paid by it pursuant to this
Article 8 in connection with such Loss.

         8.7 Indemnification Payments; Right of Offset. Subject to the terms
hereof and unless contested pursuant to Section 8.5, an Indemnifying Party shall
pay to the Indemnified Party the full amount of any and all Losses (other than
Losses resulting from an Asserted Liability) under this Article 8 within ten
days of receipt of the Claims Notice thereof and the full amount of any Loss
resulting from an Asserted Liability within ten days of the date such Litigation
is terminated or the date a final judgment or award is rendered and no appeal is
taken,

                                       11
<PAGE>   12
and thereafter the amount of such Loss shall bear interest at a rate equal to
the lesser of two percent (2%) per month or the maximum amount permitted by law.
In the event the Purchaser becomes entitled to any indemnification amount
pursuant to this Article 8, or has any claims against Sellers for breach of any
of the terms of this Agreement or any Other Agreement, then Purchaser, in
addition to any other rights it might have, shall be entitled to off-set the
amount of such claim for indemnification or breach from any further payments
owing by Purchaser to Sellers pursuant to this Agreement or any Other Agreement;
provided, however, that Purchaser shall provide Sellers with written notice of
its intent to off-set any such amount and Sellers shall have ten days in which
to cure the circumstances leading to Purchaser's claim of off-set to the
reasonable satisfaction of Purchaser prior to Purchaser's off-set of such
amount.

         8.8 Limitations on Recovery. Neither party shall make any claim against
the other for indemnification under this Agreement for a breach of a
representation or warranty contained in this Agreement unless and until the
aggregate amount of such claims exceeds $25,000. The aggregate liability of each
party hereto for breaches of representations and warranties made pursuant to
this Agreement and any claims for indemnification arising under such
representations and warranties shall be limited to the amount of the Purchase
Price; provided, however, that this limitation shall be in no way construed to
limit any remedy for fraud, willful misconduct, bad faith or any other
misrepresentation. Amounts paid as indemnification for matters described in the
proviso to the preceding sentence shall not be taken into account in determining
the limitation on the aggregate liability under this Section.

Agreements constitute the entire agreement between the parties relating to the
subject matter hereof and thereof and supersede all prior oral and written, and
all contemporaneous oral negotiations, discussions, writings and agreements
relating to the subject matter of this Agreement.

         10.3 Amendments and Waivers. This Agreement may not be amended except
in writing signed by the party against whom the change is being asserted. The
failure or delay of any party at any time or times to require performance of any
provision of this Agreement shall in no manner affect its right to enforce that
provision. No single or partial waiver by any party of any condition of this
Agreement, or the breach of any term, agreement or covenant or the inaccuracy of
any representation or warranty of this Agreement, whether by conduct or
otherwise, in any one or more instances shall be construed or deemed to be a
further or continuing waiver of any such condition, breach or inaccuracy or a
waiver of any other condition, breach or inaccuracy.

         10.4 Successors and Assigns. This Agreement shall be binding upon and
shall inure to the benefit of and be enforceable by the parties hereto, and
their respective successors and assigns, but no assignment shall relieve any
party of the obligations hereunder. This Agreement cannot be assigned by any
party without the prior written consent of the other party hereto, except by
operation of law.

         10.5 Captions; References. The captions and other headings contained in
this Agreement as to the contents of particular articles, sections, paragraphs
or other subdivisions contained herein are inserted for convenience of reference
only and are in no way to be construed as part of this Agreement or as
limitations on the scope of the particular articles, sections, paragraphs or
other subdivisions to which they refer and shall not affect the interpretation
or meaning of this Agreement. All references in this Agreement to "Section" or
"Article" shall be deemed to be references to a Section or Article of this
Agreement.

         10.6 Governing Law. This Agreement has been negotiated and executed in
the State of Georgia, will be substantially performed in the State of Georgia,
and shall be controlled, construed and enforced in accordance with the
substantive Laws of the State of Georgia, without respect to the Laws related to
choice or conflicts of Laws.

         10.7 Pronouns. All pronouns used herein shall be deemed to refer to the
masculine, feminine or neuter gender as the context requires.

Agreement (including, without limitation, the provisions of Section 5.3) be
determined to be invalid, illegal or unenforceable in any respect, the validity
and enforceability of the remaining provisions hereof shall not in any way be
affected or impaired thereby. To the extent such determination is

                                       18
<PAGE>   19
reasonably likely to give rise to a Material Adverse Effect, the parties shall
endeavor in good faith to replace the invalid, illegal or unenforceable
provisions with valid provisions the economic effect of which comes as close as
practicable to that of the invalid, illegal or unenforceable provisions.

         10.9 Remedies. Absent fraud, willful misconduct, bad faith or any other
misrepresentation, the indemnification provisions contained herein shall be the
exclusive remedy for any breach or violation of the agreements, covenants,
obligations, representations or warranties set forth in this Agreement;
provided, however, that such indemnification provisions shall not prevent any
party from seeking equitable remedies (including specific performance and
injunctive relief) in connection with any such breach or violation.

         10.10 Counterparts. This Agreement may be executed in any number of
counterparts, each of which shall be an original, but all of such counterparts
shall together constitute one and the same instrument.

         10.11 Interpretations. Neither this Agreement nor any uncertainty or
ambiguity herein shall be construed or resolved against Purchaser or Sellers,
whether under any rule of construction or otherwise. No party to this Agreement
shall be considered the draftsman. On the contrary, this Agreement has been
reviewed, negotiated and accepted by all parties and their attorneys and shall
be construed and interpreted according to the ordinary meaning of the words used
so as fairly to accomplish the purposes and intentions of all parties hereto.

         10.12 No Intention to Benefit Third Parties. Except as set forth in
Article 8, this Agreement is not intended to, and shall not, (i) benefit any
Person other than the parties who are signatories hereto or (ii) create any
third party beneficiary right in any Person.
