Shareholders of SMG, and the stock transfer books of SMG shall be closed with
respect to all shares of such SMG Common Stock outstanding immediately prior to
the Effective Time. No further transfer of any such shares of SMG capital stock
shall be made on such stock transfer books after the Effective Time. If, after
the Effective Time, a valid certificate previously representing any of such
shares of SMG Common Stock (an "SMG Stock Certificate") is presented to HALIS,
such SMG Stock Certificate shall be canceled and shall be exchanged as provided
in Section 1.7.

     1.7  EXCHANGE OF CERTIFICATES.

          (a) At the Closing, each Shareholder shall surrender its respective
SMG Stock Certificate(s) to the Surviving Corporation, together with such
transmittal documents as the Surviving Corporation may reasonably require, and
the Surviving Corporation shall deliver to such Shareholder a certificate of
HALIS Common Stock representing such Shareholder's pro rata share of the
aggregate Merger Consideration to be paid at Closing pursuant to Section 1.8.

          (b) No fractional shares of HALIS Common Stock shall be issued in
connection with the Merger, and no certificates for any such fractional shares
shall be issued.  In lieu of such fractional shares, any Shareholder who would
otherwise be entitled to receive a fraction of a share of HALIS Common Stock
(after aggregating all fractional shares of HALIS Common Stock issuable to such
holder) shall, upon surrender of such Shareholder's SMG Stock Certificate(s), be
paid in cash at a rate of $2.00 per share in lieu of such fractional shares.

          (c) Until surrendered as contemplated by this Section 1.7, each SMG
Stock Certificate shall be deemed, from and after the Effective Time, to
represent only the right to receive a pro rata share of the Merger
Consideration.  If any SMG Stock Certificate shall have been lost, stolen or
destroyed, HALIS may, in its discretion and as a condition precedent to the
issuance of any certificate representing HALIS Common Stock, require the owner
of such lost, stolen or destroyed SMG Stock Certificate to provide an
appropriate affidavit and to deliver a bond (in such sum as HALIS may reasonably
direct) as indemnity against any claim that may be made against HALIS with
respect to such SMG Stock Certificate.

          (d) The shares of HALIS Common Stock to be issued in the Merger shall
be characterized as "restricted securities" for purposes of Rule 144 under the
Securities Act, and each certificate representing any of such shares shall bear
a legend identical or similar in effect to the following legend (together with
any other legend or legends required by applicable state securities laws or
otherwise):

          THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE
          SECURITIES ACT OF 1933 (THE "ACT") AND MAY NOT BE OFFERED, SOLD OR
          OTHERWISE TRANSFERRED, ASSIGNED, PLEDGED OR HYPOTHECATED UNLESS AND
          UNTIL REGISTERED UNDER THE ACT OR UNLESS THE COMPANY HAS RECEIVED AN

<PAGE>
 
          OPINION OF COUNSEL SATISFACTORY TO THE COMPANY AND ITS COUNSEL THAT
          SUCH REGISTRATION IS NOT REQUIRED.

          (e) HALIS shall be entitled to deduct and withhold from any
consideration payable or otherwise deliverable to any holder or former holder of
SMG Common Stock pursuant to this Agreement such amounts as HALIS may be
required to deduct or withhold therefrom under the Code or under any provision
of state, local or foreign tax law.  To the extent such amounts are so deducted
or withheld, such amounts shall be treated for all purposes under this Agreement
as having been paid to the Person to whom such amounts would otherwise have been
paid.

          (f) HALIS shall not be liable to any holder or former holder of SMG
Common Stock for any shares of HALIS Common Stock (or dividends or distributions
with respect thereto), or for any cash amounts, delivered to any public official
pursuant to, and in compliance with, any applicable abandoned property, escheat
or similar law.

     1.8  MERGER CONSIDERATION.

     (a)  The aggregate merger consideration to be paid by HALIS to the
Shareholders  in consideration of the Merger  ("Merger Consideration") shall
consist of the Initial Merger Consideration and, subject to subparagraphs
1.8(c), (d), (e), (f) and (g) below, the Contingent Merger Consideration, each
as hereinafter defined.

     (b)  The Initial Merger Consideration shall consist of 3,072,000 shares of
HALIS Common Stock.  The Initial Merger Consideration shall be paid to the
Shareholders on a pro-rata basis determined by the number of outstanding shares
of SMG Common Stock on the Closing Date. Certificates representing the Initial
Merger Consideration shall be delivered to the Shareholders at Closing or at
such later date as the Shareholders may agree.

     (c)  The Contingent Merger Consideration shall consist of shares of HALIS
Common Stock having an aggregate value calculated in accordance with
subparagraph 1.8(e) below.  Certificates representing the Contingent Merger
Consideration, if any, will be delivered to the Shareholders not later than 30
days after the final Cash Flow, Net Income and Revenues Determination (as
defined in subparagraph 1.8(g)) in accordance with subparagraph 1.8(g).

     (d)  The Contingent Merger Consideration shall be payable to the
Shareholders only if all of the following conditions are met:

          (i) the Surviving Corporation shall have positive Cash Flow (as
     defined in subparagraph 1.8(f)) for the fiscal year ending December 31,
     1997 (the "Determination Period");

          (ii) the Surviving Corporation shall have Net Income (as defined in
     subparagraph 1.8(f)) of at least $1.00 for the Determination Period; and

                                       4
<PAGE>
 
          (iii) the Surviving Corporation shall have Revenues (as defined in
     subparagraph 1.8(f)) of more than $2,800,000 for the Determination Period.

     (e)  If all the conditions set forth in subparagraph 1.8(d) above are met,
the Contingent Merger Consideration shall be calculated as follows.  The
Contingent Merger Consideration shall equal that number of shares of HALIS
Common Stock having an aggregate value, based on a per share price equal to the
higher of (i) $1.75 or (ii) the average bid and ask price of HALIS Common Stock
for the final ten trading days of calendar year 1997, equal to the product of
(Y) the amount by which Revenues of the Surviving Corporation for the
Determination Period exceeds $2,800,000, multiplied by (Z) two.

     (f)  For purposes of calculation of the Contingent Merger Consideration,
the following definitions shall apply:

          (i) "Cash Flow" shall mean all cash funds derived from operations,
     without reduction for any non-cash charges, but less funds used to pay
     current operating expenses, determined in accordance with generally
     accepted accounting principles;

          (ii) "Net Income" shall mean net income, determined in accordance with
     generally accepted accounting principles; and

          (iii) "Revenues" shall mean total income on an accrual basis,
     determined in accordance with generally accepted accounting principles.

     For purposes of calculation of the Contingent Merger Consideration only,
Cash Flow, Net Income and Revenues of the Surviving Corporation shall also
include the Cash Flow, Net Income and the Revenues for SMG from and after
January 1, 1997 through the Closing Date.

     (g)  For purposes of calculation of the Contingent Merger Consideration,
the Cash Flow, Net Income and Revenues of the Surviving Corporation for the
Determination Period shall be determined by the Surviving Corporation's
independent certified public accountants within 120 days following the end of
the Determination Period (the "Cash Flow, Net Income and Revenues
Determination").  Within five business days after receiving the Cash Flow, Net
Income and Revenues Determination, HALIS shall deliver same to the Shareholders'
Agent (as defined in Section 11.1).  If the Shareholders' Agent does not deliver
a list of written objections to the Cash Flow, Net Income and Revenues
Determination ("Objection Notice") to HALIS within 30 days following delivery to
the Shareholders' Agent, the Cash Flow, Net Income and Revenues Determination
shall become final and binding upon the parties.  If the Shareholders' Agent
delivers an Objection Notice within such 30-day period, the parties will
endeavor to reconcile any differences and agree upon a final Cash Flow, Net
Income and Revenues Determination.  If the parties are unable to agree upon a
final Cash Flow, Net Income and Revenues Determination within 30 days following
delivery of the Objection Notice, at the request of either party the outstanding
matters shall be submitted for resolution by a mutually acceptable accounting
firm of recognized national or regional standing with offices in the Atlanta

                                       5

area. If the parties are unable to agree upon a mutually acceptable accounting
firm, one will be selected by HALIS at random from a list of the ten largest
Atlanta offices of certified public accounting firms having no prior affiliation
with HALIS, SMG, the Surviving Corporation or the Shareholders. Each of HALIS
and the Shareholders shall bear 50% of the fees and expenses of the accounting
firm so selected. Such accounting firm shall promptly prepare a final Cash Flow,
Net Income and Revenues Determination and its conclusions shall be final and
binding upon the parties.

     1.9  TAX CONSEQUENCES.  For federal income tax purposes, the Merger is
intended to constitute a reorganization within the meaning of Section 368 of the
Code.  The parties to this Agreement hereby adopt this Agreement as a "plan of
reorganization" within the meaning of Sections 1.368-2(g) and 1.368-3(a) of the
United States Treasury Regulations.

     1.10 FURTHER ACTION.  If, at any time after the Effective Time, any
further action is reasonably determined by HALIS to be necessary or desirable to
carry out the purposes of this Agreement or to vest Subsidiary with full right,
title and possession of and to all rights and property of SMG, the officers and
directors of HALIS shall be fully authorized (in the name of SMG and otherwise)
to take such action.

Except as set forth in Part 2.22 of the Disclosure Schedule, SMG is not and will
not be required to make any filing with or given any notice to, or to obtain any
Consent from, any Person in connection with (x) the execution, delivery or

                                       22
<PAGE>
 
which SMG claims any proprietary rights (the "Software"). Part 2.23 of the
Disclosure Schedule lists all employees and independent contractors who
participated materially in the creation or material modification of the
Software. Except as described in Part 2.23 of the Disclosure Schedule, SMG is
the exclusive owner or licensee of all patents, copyrights, trademarks,
intellectual property rights, trade secrets and other proprietary information,
processes, and formulae used in connection with the Software. All development or
other work performed by employees, independent contractors or others in
connection with the Software on behalf of SMG has been either (i) pursuant to a
"work-for-hire" arrangement or agreement with SMG in accordance with applicable
state and federal law, that has accorded SMG full, effective, exclusive and
original ownership of all tangible and intangible property arising thereby or
(ii) subject to an executed instrument of assignment in favor of SMG that has
conveyed to SMG full, effective and exclusive ownership of all tangible and
intangible property arising in connection with the work performed. SMG has
exclusive ownership, possession and control of all source codes, system
documentation, statements of principles of operation, and schematics for all the
Software that may be necessary to render such materials understandable and
usable by a trained computer programmer. The Software is not in the public
domain. SMG has taken adequate measures consistent with industry practice to
safeguard the confidentiality of any confidential information or trade secrets
relating to the Software. There are no licenses, covenants not to compete or
other agreements or arrangements which restrict in any way SMG's right to
further develop, market, license and use the Software. The Software performs in
all material respects in accordance with the documentation and other written
material used in connection with the Software and is free from material defects
in programming or operation. To the knowledge of SMG and the Shareholders, SMG
is not infringing or otherwise acting adversely to the right of any party under
or in respect to the Software. There is no claim for damages or any proceeding
pending, or to the knowledge of SMG and the Shareholders threatened, with
respect thereto, and SMG and the Shareholders have no knowledge that any third
party is infringing or otherwise acting adversely to the right of SMG under or
in respect to any Software owned by SMG. All Software owned or developed by SMG
that is licensed to third parties has been distributed pursuant to license
agreements, substantially in the form attached on Part 2.23 of the Disclosure
Schedule, and no person has been given or permitted to use any such Software
unless such persons have executed a license agreement substantially in the form
attached on Part 2.23 of the Disclosure Schedule.

     2.24 FULL DISCLOSURE.  This Agreement (including the Disclosure
Schedule) does not, and Shareholders' Closing Certificate (as defined in Section
6.4(f)) will not, (i) contain any representation, warranty or information that
is false or misleading with respect to any material fact, or (ii) omit to state
any material fact necessary in order to make the representations, warranties and
information contained and to be contained herein and therein not false or

that representations and warranties contained in Sections 2.6, 2.9, 2.14 and
2.15 shall survive until expiration of the applicable statutes of limitation for

reserves were established therefor;

          (b) any breach of any representation and warranty contained in this
Agreement or any misrepresentation in or omission on the part of SMG or the

Corporation to continue to operate the business of SMG in the manner presently

          (e) the failure of the Surviving Corporation to collect any accounts
receivable of SMG existing on the Closing Date, net of reserve for bad debts set

provided however, that upon receipt of full payment from Shareholders, the

certificate furnished or to be furnished to the Shareholders by HALIS or the
Subsidiary pursuant to this Agreement.

      9.4 INDEMNIFICATION PROCEDURE.

          (a) Upon obtaining knowledge thereof, the party to be indemnified
hereunder (the "Indemnitee") shall promptly notify the indemnifying party
hereunder (the "Indemnitor") in writing of any damage, claim, loss, liability or
expense or other matter which the Indemnitee has determined has given or could
give rise to a claim for which indemnification rights are granted hereunder
(such written notice referred to as the "Notice of Claim").  The Notice of Claim
shall specify, in all

                                       36
<PAGE>
 
reasonable detail, the nature and estimated amount of any such claim giving rise
to a right of indemnification, to the extent the same can reasonably be
estimated.  Any failure on the part of an Indemnitee to give timely notice to
the Indemnitor of a claim shall not affect the right of the Indemnitee to obtain
indemnification from the Indemnitor with respect to such claim unless the
Indemnitor is actually harmed by such failure to notify, and only to the extent
of such actual harm.

          (b) With respect to any matter set forth in a Notice of Claim relating
to a third party claim the Indemnitor shall defend, in good faith and at its
expense, any such claim or demand, and the Indemnitee, at its expense, shall
have the right to participate in the defense of any such third party claim.  So
long as Indemnitor is defending, in good faith, any such third party claim, the
Indemnitee shall not settle or compromise such third party claim.  The
Indemnitee shall make available to the Indemnitor or its representatives all
records and other materials reasonably required by them for use in contesting
any third party claim and shall cooperate fully with the Indemnitor in the
defense of all such claims.  If the Indemnitor does not defend any such third
party claim or if the Indemnitor does not provide the Indemnitee with prompt and
reasonable assurances that the Indemnitor will satisfy the third party claim,
the Indemnitee may, at its option, elect to defend any such third party claim,
at the Indemnitor's expense.  An Indemnitor may not settle or compromise any
claim without obtaining a full and unconditional release of the Indemnitee,
unless the Indemnitee consents in writing to such settlement or compromise.
Notwithstanding the foregoing, if there is a reasonable probability that a third
party claim for which the HALIS or the Surviving Corporation has indemnification
rights against Cone  hereunder will materially and adversely affect HALIS or the
Surviving Corporation other than as a result of money damages or other payments,
HALIS or the Surviving Corporation  shall be entitled to conduct the defense of
such claim at Cone's expense.

      9.5 SET-OFF.  HALIS and the Surviving Corporation shall have the right to
set-off and apply against any other amounts owing from HALIS or the Surviving
Corporation to the Shareholders under any other agreement between HALIS or the
Surviving Corporation and Shareholders, all sums in respect of which the
Shareholders may be liable pursuant to Section 9.2 hereof, such right of set-off
to be in addition to and not in lieu of or an election against any and all other
remedies available to HALIS and the Surviving Corporation under this Agreement
or at law or in equity.

      9.6 LIMITATIONS ON LIABILITY OF THE SHAREHOLDERS.

          (a) The Shareholders shall have no liability with respect to Losses of
HALIS arising under subparagraphs (a), (b), or (d) of Section 9.2 until the
total of all Losses of HALIS with respect thereto exceeds $100,000.  If the
aggregate Losses of HALIS exceed such $100,000 threshold, SMG and the
Shareholders shall be liable for all Losses of HALIS to the extent (and only to
the extent) Losses of HALIS exceed such $100,000 threshold.

          (b) Notwithstanding anything to the contrary within this Agreement,
the obligations of the Shareholders to indemnify HALIS, SMG, the Subsidiary and
the Surviving Corporation (and their respective directors, officers, employees,
agents, affiliates, successors and

                                       37
<PAGE>
 
assigns) are subject to the following provisions.  The amount of any
indemnification which may be claimed from the Shareholders hereunder shall be
calculated to be the cost or loss to such party after giving effect to:  (i) any
insurance proceeds receivable by such party in relation to the matter which is
the subject of such claim and (ii) the value of any related, determinable tax
benefits realized, or which will (with reasonable certainty) be realized within
a two year period following the date of incurring such loss or cost in relation
to the matter which is the subject of such claim.  HALIS agrees that it shall
cause the Surviving Corporation to purchase and maintain for a period of at
least two years after the Closing Date general comprehensive liability insurance
(which shall contain endorsements providing for product liability insurance)
with deductibles and limits of coverage equal or better to that presently
maintained by SMG with an insurance company reasonably satisfactory to the
Shareholders, providing coverage for claims arising from occurrences or matters
occurring prior to the Closing Date.

            (c) Notwithstanding any of the other provisions of this Agreement or
any Agreement, certificate or other document made in order to carry out the
transactions contemplated herein, the maximum aggregate liability of the
Shareholders in respect of all claims pursuant to this Agreement, whether for
breach of representation and warranty, indemnification or otherwise, will be
limited to an amount equal to the aggregate value of the Merger Consideration,
determined as of the respective dates of issuance of the Initial Merger
Consideration and the Contingent Merger Consideration, if any.

<PAGE>
 
registration effected pursuant to Section 10.3, the reasonable fees and

      10.2  REGISTRATION UNDER SECURITIES ACT, ETC.

      Registration on Request.
      ----------------------- 

            (a) Request.  At any time during the period commencing January 1, 
                -------                                     
1998 and ending December 31, 1998, if HALIS has not caused the registration of
all the Registrable Securities pursuant to Section 10.3 below, upon the written
request of one or more Initiating Holders, requesting that HALIS effect the
registration under the Securities Act of all or part of such Initiating Holders'
Registrable Securities (but not less than 25% of the Registrable Securities
outstanding) and specifying the intended method or methods of disposition
thereof, HALIS will promptly, but in any event within 10 business days, give
written notice of such requested registration to all holders of Registrable
Securities and thereupon will use its best efforts to effect the registration
under the Securities Act of:

            (i)   the Registrable Securities which HALIS has been so requested
      to register by such Initiating Holders, for disposition in accordance
      with the intended method or methods of disposition stated in such
      request,

            (ii) all other Registrable Securities which HALIS has been requested
      to register by the holders thereof by written request delivered to HALIS
      within 10 days after the giving of such written notice by HALIS (which
      request shall specify the intended method or methods of disposition of
      such Registrable Securities), and

            (iii) all shares of HALIS Common Stock which HALIS may elect to
      register for its own account in connection with the offering of
      Registrable Securities pursuant to this Section 10.2,

all to the extent requisite to permit the disposition (in accordance with the
intended methods thereof as aforesaid) of the Registrable Securities so to be
registered, provided that HALIS shall not be required to effect more than one
            --------                                                         
registration pursuant to this Section 10.2.

            (b) Registration Statement Form.  Each registration requested 
                --------------------------- 
pursuant to this Section 10.2 shall be effected by the filing of a registration
statement on any form which HALIS is eligible to use, such form to be selected
by HALIS, after consultation with counsel and after notice of such selection of
such form is delivered to the holders of all Registrable Securities electing to
participate in such registration; provided, however, that if the holders of at
least a majority of the Registrable Securities as to which registration has been
requested pursuant to this Section 10.2 shall so request, HALIS shall file such
registration statement pursuant to the SEC's Rule 415, or any successor rule or
regulation thereto, so as to permit the continuous or delayed offering of the
Registrable Securities in accordance with the intended method of disposition
specified in the Initiating Holder's notice pursuant to sub-section (a) of this
Section 10.2, but in no event shall

                                       39
<PAGE>
 
HALIS be required to maintain the effectiveness of such registration beyond the
period specified in Section 10.4(b).

          (c) Expenses.  Except as otherwise prohibited by applicable law, HALIS
              --------                                                          
will pay all Registration Expenses in connection with the registration of
Registrable Securities requested pursuant to this Section 10.2.

          (d) Effective Registration Statement.  A registration requested
              --------------------------------                           
pursuant to this Section 10.2 shall not be deemed to be effected unless it has
been declared effective by the SEC or otherwise becomes effective, provided that
                                                                   --------     
a registration which does not become effective after HALIS has substantially
prepared and has filed or is in a position to file a registration statement with
respect thereto solely by reason of the refusal to proceed of all of the
Initiating Holders (other than any refusal to proceed based upon the advice of
their counsel that the registration statement, or the prospectus contained
therein, contains an untrue statement of a material fact or omits to state a
material fact required to be stated therein or necessary to make the statements
therein not misleading in the light of the circumstances then existing) shall be
deemed to have been effected by HALIS pursuant to this Section 10.2.

          (e) Registration Rights Exclusive.  HALIS will not register securities
              -----------------------------                                     
for sale for the account of any person other than the holders of Registrable
Securities, and will not, in any event, register any securities other than
Registrable Securities, in any registration of Registrable Securities requested
by one or more holders pursuant to this Section 10.2 (except for shares to be
registered by or on behalf of HALIS where the underwriter, if any, does not
object to the inclusion of such Company shares in the registration), unless, in
each such case, permitted to do so by the written consent of such holders
representing at least 51% (by number of shares) of the Registrable Securities as
to which registration has been requested by such holders.  HALIS will not grant
to any Person the right to request a registration of securities prohibited by
this subdivision (e).

          (f) Separate Transferability of Demand Registration Rights.  In
              ------------------------------------------------------     
connection with the transfer of any portion or portions of the Registrable
Securities, any Shareholder may, at its sole election, transfer the demand
registration entitlement granted by this Section 10.2 to and for the exclusive
benefit of the Registrable Securities so transferred or may retain one or both
of such demand registration entitlements for the exclusive benefit of the
holders of the retained Registrable Securities.  In such event, the terms
"Initiating Holders" and "Registrable Securities" shall, for the purposes of
this Section 10.2, refer exclusively to the Registrable Securities for whose
benefit such rights have been transferred or retained, as the case may be.  Such
Shareholders shall effect the transfer or retention of demand registration
rights hereunder by giving notice to HALIS concurrently with any transfer of
Registrable Securities.  Once the Shareholder has made a transfer of Registrable
Securities without retaining the exclusive benefit of such rights to its
retained Registrable Securities, it shall not thereafter, without the express
written consent of the subsequent holders of such transferred Registrable
Securities, purport to grant or retain demand registration rights to the
exclusive benefit of any subset of the Registrable Securities.  Nothing
contained in this Section 10.2(f) shall be construed to require HALIS to effect
more than one such demand registration pursuant to Section 10.2.

      10.3  INCIDENTAL REGISTRATION.  (a) Right to Include Registrable
                                          ----------------------------
Securities.  If, at any time on or before December 31, 1997, HALIS proposes to
- ----------                                                                    
register any of its equity securities under the Securities Act, whether or not
for sale for its own account, or if either Larry Fisher or Paul Harrison
proposes to register any of their HALIS Common Stock under the Securities Act
for sale for his own account (HALIS, Fisher or Harrison, as the case may be,
hereinafter in this Section 10 referred to as the "Registering Party"), on a
form and in a manner which would permit registration of Registrable Securities
held by any Shareholder for sale to the public under the Securities Act, the
Registering Party will each such time give prompt written notice to all holders
of Registrable Securities of his or its intention to do so, describing such
securities and specifying the form and manner and the other relevant facts
involved in such proposed registration, and upon the written request of any such
holder delivered to the Registering Party within ten (10) business days after
the giving of any such notice (which request shall specify the Registrable
Securities intended to be disposed of by such holder and the intended method or
methods of disposition thereof), the Registering Party will use its best efforts
to effect the registration under the Securities Act of all Registrable
Securities which the Registering Party has been so requested to register by the
holders of Registrable Securities (hereinafter "Requesting Holder"), to the
extent requisite to permit the disposition (in accordance with the intended
methods thereof as aforesaid) of the Registrable Securities so to be registered,
                                                                                
provided that:
- --------      

          (i) if, at any time after giving such written notice of its intention
     to register any of its securities and prior to the effective date of the
     registration statement filed in connection with such registration, the
     Registering Party shall determine for any reason not to register such
     securities, the Registering Party may, at its election, give written notice
     of such determination to each holder of Registrable Securities and
     thereupon shall be relieved of its obligation to register any Registrable
     Securities in connection with such registration (but not from its
     obligation to pay the Registration Expenses in connection therewith as
     provided in subdivision (b) of this Section 10.3);

          (ii) if (A) the registration so proposed by the Registering Party
     involves an underwritten offering of the securities so being registered,
     whether or not for sale for the account of HALIS, to be distributed by or
     through one or more underwriters of recognized standing under underwriting
     terms appropriate for such a transaction, (B) the Registering Party
     proposes that the securities to be registered in such underwritten offering
     will include all of the Registrable Securities requested to be so included,
     and (C) the managing underwriter of such underwritten offering shall advise
     the Registering Party in writing that, in its judgment, the distribution of
     all or a specified portion of such Registrable Securities concurrently with
     the securities being distributed by such underwriters will materially
     adversely affect the distribution of such securities by such underwriters
     (such written advice to state the reasons therefor), then the Registering
     Party will promptly furnish each such holder of Registrable Securities with
     a copy of such opinion and may require, by written notice to each such
     holder accompanying such written advice, that the distribution of all or a
     specified portion of such Registrable Securities be excluded from such
     distribution. In the case of an exclusion of a portion of such Registrable
     Securities for a registration by HALIS

                                       41
<PAGE>
 
     of its securities for its own account, HALIS shall cause the portion of the
     Registerable Securities to be excluded (together with all other securities
     to be registered by holders other than the Shareholders) to be allocated
     among the Shareholders (and such other holders) in proportion to the
     respective number of shares of Registrable Securities and shares of other
     securities so requested to be registered by the Shareholders and such other
     holders. In the case of an exclusion of a portion of such Registrable
     Securities in the case of a registration by either Larry Fisher or Paul
     Harrison of securities for their own account, Larry Fisher or Paul
     Harrison, as the case may be, shall reduce the number of shares they wish
     to register, and the reduction of shares to be registered shall be
     allocated in proportion to the respective number of shares of Registrable
     Securities so requested to be registered by the Shareholders and the number
     of shares attempted to be registered by Larry Fisher or Paul Harrison; and

           (iii) HALIS shall not be obligated to effect any registration of
     Registrable Securities under this Section 10.3 incidental to the
     registration of any of its securities in connection with mergers,
     acquisitions, exchange offers, dividend reinvestment plans or stock option
     or other employee benefit plans or incidental to the registration of any
     non-equity securities not convertible into equity securities.

     (b)   Expenses.  Except as otherwise prohibited by applicable law, the
           --------                                                        
Registering Party will pay all Registration Expenses in connection with each
registration of Registrable Securities requested pursuant to this Section 10.

      10.4 REGISTRATION PROCEDURES.  If and whenever HALIS is required to

                                       42

agreement), and (ii) a "comfort" letter, dated the effective date of such
registration statement (and, if such registration includes an underwritten
public offering, dated the date of the closing under the underwriting

with respect to events subsequent to the date of such financial statements, as
are customarily covered in opinions of issuer's counsel and in accountants'

          (f) immediately notify each seller of Registrable Securities covered

untrue statement or omission requires amendment of the

                                       43
<PAGE>

      10.5 UNDERWRITTEN OFFERINGS.

           (a) Underwritten Offerings Exclusive.  Whenever a registration
               --------------------------------                          
requested by one or more Holders pursuant to Section 10.2 is for an underwritten
offering, only shares of Registrable Securities which are to be distributed by
the underwriters designated by such holders may be included in such
registration, unless such holders shall have permitted other securities to be
included in such registration as provided in Section 10.2(e).  If such holders
shall determine that the number of shares of Registrable Securities and any such
other securities to be sold in any such underwritten offering should be limited
due to market conditions or otherwise, HALIS shall include in such registration
to the extent of the number which HALIS is so advised can be sold in such
offering (i) first, Registrable Securities requested to be included in such
registration, pro rata among the

                                       44
<PAGE>
 
holders of such Registrable Securities on the basis of the number of shares of
such securities requested to be included by such holders, and (ii) second, other
securities of HALIS proposed to be included in such registration, in accordance
with the priorities, if any, then existing among HALIS and the holders of such
securities.

          (b) Underwriting Agreement.  If requested by the underwriters for any
              ----------------------                                           
underwritten offering of Registrable Securities on behalf of a holder or holders
of Registrable Securities pursuant to a registration requested under Section
10.2, HALIS will enter into an underwriting agreement reasonably acceptable to
HALIS with such underwriters for such offering, such agreement to contain such
representations and warranties by HALIS and such other terms and provisions as
are customarily contained in underwriting agreements with respect to secondary
distributions, including, without limitation, indemnities to the effect and to
the extent provided in Section 10.2.  The holders of Registrable Securities on
whose behalf Registrable Securities are to be distributed by such underwriters
shall be parties to any such underwriting agreement and the representations and
warranties by, and the other agreements on the part of, HALIS to and for the
benefit of such underwriters, shall also be made to and for the benefit of such
holders of Registrable Securities.  Such holders of Registrable Securities shall
not be required by HALIS to make any representations or warranties to or
agreements with HALIS or the underwriters other than reasonable representations,
warranties or agreements (including indemnity agreements customary in secondary
offerings) regarding such holder, such holder's Registrable Securities and such
holder's intended method or methods of disposition and any other representation
required by law.

          (c) Incidental Underwritten Offerings.  If a Registering Party at any
              ---------------------------------                                
time proposes to register any of its securities under the Securities Act as
contemplated by Section 10.3 and such securities are to be distributed by or
through one or more underwriters, the Registering Party will use its best
efforts, if requested by any holder of Registrable Securities who requests
incidental registration of Registrable Securities in connection therewith
pursuant to Section 10.3, to arrange for such underwriters to include the
Registrable Securities to be offered and sold by such holder among the
securities to be distributed by or through such underwriters, provided that, for
                                                              --------          
purposes of this sentence, best efforts shall not require the Registering Party
to reduce the amount or sale price of such securities proposed to be distributed
by or through such underwriters.  The holders of Registrable Securities to be
distributed by such underwriters shall be parties to the underwriting agreement
between the Registering Party and such underwriters and the representations and
warranties by, and the other agreements on the part of, the Registering Party to
and for the benefit of such underwriters, shall also be made to and for the
benefit of such holders of Registrable Securities, and the Registering Party
will cooperate with such holders of Registrable Securities to the end that the
conditions precedent to the obligations of such holders of Registrable
Securities under such underwriting agreement shall not  include conditions that
are not customary in underwriting agreements with respect to combined primary
and secondary distributions and shall be otherwise satisfactory to such holders.
Such holders of Registrable Securities shall not be required by the Registering
Party to make any representations or warranties to or agreements with the
Registering Party or the underwriters other than reasonable representations,
warranties or agreements (including indemnity agreements customary in secondary
offerings) regarding such

                                       45
<PAGE>
 
holder, such holder's Registrable Securities and such holder's intended method
or methods of distribution and any other representation required by law.

          (d)  Selection of Underwriters.  Whenever a registration requested
               -------------------------                                    
pursuant to Section 10.2 is for an underwritten offering, the holders of a
majority of the Registrable Securities included in such registration shall have
the right to select the managing underwriter(s) to administer the offering,
after consulting with HALIS as to such selection and subject to the approval of
HALIS, which approval will not be unreasonably withheld.  If HALIS at any time
proposes to register any of its securities under the Securities Act for sale for
its own account and such securities are to be distributed by or through one or
more underwriters, the selection of the managing underwriter(s) shall be made by
HALIS and notice of the selection thereof delivered to the holders of all
Registrable Securities eligible to participate in such registration.

          (e)  Holdback Agreements.  (i) If any registration pursuant to Section
               -------------------                                              
10.2 or 10.3 shall be in connection with an underwritten public offering, each
holder of Registrable Securities agrees by acquisition of such Registrable
Securities, if so required by the managing underwriter, not to effect any public
sale or distribution of Registrable Securities (other than as part of such
underwritten public offering) within seven days prior to the effective date of
such registration statement or 120 days after the effective date of such
registration statement.

          (ii) HALIS agrees (A) not to effect any public sale or distribution of
any of its equity securities or securities convertible into or exchangeable or
exercisable for any of such securities during the seven days prior to and the
earlier of 90 days after any underwritten registration pursuant to Section 10.2
or 10.3 has become effective and the date on which all securities under such
registration statement are sold, except as part of such underwritten
registration and except pursuant to registrations on Form S-8 or any successor
thereto, and (B) use its best efforts to cause each holder of its equity
securities or any securities convertible into or exchangeable or exercisable for
any of such securities, in each case purchased from HALIS at any time after the
date of this Agreement (other than in a public offering) to agree not to effect
any such public sale or distribution of such securities during such period.

     10.6 PREPARATION; REASONABLE INVESTIGATION.  In connection with the
preparation and filing of each registration statement registering Registrable
Securities under the Securities Act, HALIS will give the holders of Registrable
Securities on whose behalf such Registrable Securities are to be so registered
and their underwriters, if any, each Requesting Holder, and their respective
counsel and accountants, the opportunity to participate in the preparation of
such registration statement, each prospectus included therein or filed with the
SEC and each amendment thereof or supplement thereto, and will give each of them
such access to its books and records and such opportunities to discuss the
business of HALIS with its officers and the independent public accountants who
have certified its financial statements as shall be necessary in the opinion of
such holders and such underwriters or their respective counsel, to conduct a
reasonable investigation within the meaning of the Securities Act.  To minimize
disruption and expense to HALIS during the course of the registration process,
sellers of Registrable Securities to be covered by any such

                                       46

              ------------------------                                          
securities of HALIS under the Securities Act, HALIS will, and hereby does (or in
the case of a registration by Larry Fisher and Paul Harrison for their own
account, Fisher and Harrison will and hereby do), indemnify and hold harmless in
the case of any registration statement filed pursuant to Section 10.2 or 10.3,

Securities Act against any losses, claims, damages, liabilities or expenses,
joint or several, to which such seller or Requesting Holder or any such director
or officer or participating or controlling person may become subject under the
Securities Act or otherwise, insofar as such losses, claims, damages,
liabilities or expenses (or actions or proceedings in respect thereof) arise out
of or are based upon (i) any untrue statement or alleged untrue statement of any
material fact contained in any registration statement under which such
securities were registered under the Securities Act, any preliminary prospectus,
final prospectus or summary prospectus contained therein, or any amendment or
supplement thereto, or any document incorporated by reference therein, or (ii)
any omission or alleged omission to state therein a material fact required to be
stated therein or necessary to make the statements therein not misleading, and

case to the extent that any such loss, claim, damage, liability or expense (or
action or proceeding in respect thereof) arises out of or is based upon an
untrue statement or alleged untrue statement or omission or alleged omission
made in such registration statement, any such preliminary prospectus, final
prospectus, summary prospectus, amendment or supplement in reliance upon and in

or such Requesting Holder or any such director, trustee, officer, participating
person or controlling person specifically stating that it is for use in the
preparation thereof.  Such indemnity shall remain in full force and effect
regardless of any investigation made by or on behalf of such seller or such
Requesting Holder or any such director, officer, participating person or
controlling person and shall survive the transfer of such securities by such
seller.  HALIS shall agree to make provision for contribution relating to such
indemnity as shall be reasonably requested by any seller of Registrable
Securities or the underwriters.

          (b) Indemnification by the Sellers.  HALIS may require (or in the case
              ------------------------------

HALIS, each officer of HALIS who shall sign such registration statement and each
other person, if any, who controls HALIS within the meaning of the Securities
Act, with respect to any statement in or omission from such registration
statement, any preliminary prospectus, final prospectus or summary prospectus
included therein, or any amendment or supplement thereto, if such statement or
omission was made in reliance upon and in conformity with written information
furnished to HALIS (or Larry Fisher or Paul Harrison, as the case may be)
through an instrument only executed by such seller specifically stating that it
is for use in the preparation of such registration statement, preliminary
prospectus, final prospectus, summary prospectus, amendment or supplement.  Such
indemnity shall remain in full force and effect regardless of any investigation
made by or on behalf of HALIS or any such director, officer or controlling
person and shall survive the transfer of such securities by such seller.

claim referred to in the preceding subdivisions of this section 10.7, such
indemnified party will, if a claim in respect thereof is to be made against any
indemnifying party, give written notice to the latter of the commencement of

under the preceding subdivisions of this Section 10.7.  In case any such action
is brought against an indemnified party, unless in such indemnified party's
reasonable judgment a conflict of interest between such indemnified and
indemnifying parties may exist in respect of such claim, the indemnifying party
shall be entitled to participate in and to assume the defense thereof, jointly
with any other indemnifying party similarly notified, to the extent that it may
wish, with counsel reasonable satisfactory to such indemnified party, and after
notice from the indemnifying party to such indemnified party of its election so

such indemnified party for any legal or other expenses subsequently incurred by
the latter in connection with the defense thereof other than reasonable costs of
investigation.  No indemnifying party shall, without the consent of the
indemnified party, consent to entry of any judgment or enter into any settlement

      10.8    AMENDMENTS AND WAIVERS.  The provisions of this Section may be
amended and HALIS (or Larry Fisher or Paul Harrison, as the case may be) may
take any action herein prohibited, or omit to perform any act herein required to
be performed by it, only if HALIS shall have obtained the written consent to
such amendment, action or omission to act, of the holder or holders of 51% or
more of the shares of Registrable Securities (and, in the case of any amendment,
action or omission to act which adversely affects any specific holder of

Registrable Securities are held by a nominee for the beneficial owner thereof,
the beneficial owner thereof may, at its election, be treated as the holder of
such Registrable Securities for purposes of any request or other action by any
holder or holders of Registrable Securities pursuant to this Agreement or any
determination of any number or percentage of shares of Registrable Securities
held by any holder or holders of Registrable Securities contemplated by this
Agreement.  If the beneficial owner of any Registrable Securities so elects,
HALIS (or Fisher or Harrison, as the case may be) may require assurances
reasonably satisfactory to it of such owner's beneficial ownership of such
Registrable Securities.
