Item 5.  Other Events.

     On April 16, 1998, XcelleNet, Inc., a Georgia corporation ("XcelleNet"),
entered into an Agreement and Plan of Merger (the "Merger Agreement), by and
among Sterling Commerce, Inc., a Delaware corporation ("Sterling"), Sterling
Commerce (Southern), Inc., a Delaware corporation and a wholly owned subsidiary
of Sterling ("Sub"), and XcelleNet providing for the acquisition of XcelleNet by
Sterling.  Pursuant to the Merger Agreement, following the satisfaction of the
conditions contained therein, XcelleNet will be merged with and into Sub, with
Sub to continue as the surviving corporation wholly owned by Sterling (the
"Merger"). 

     In the Merger, each share of XcelleNet's common stock, par value $.01 per
share (the "XcelleNet Common Stock") issued and outstanding immediately prior to
the effective time of the Merger will be converted into the right to receive the
"Merger Consideration," which term is defined as (i) a cash payment in an amount
equal to $8.80 (the "Cash Payment") and (ii) 0.2885 of a share of Sterling's
common stock, par value $.01 per share ("Sterling Common Stock"); with the ratio
of cash and shares to be adjusted, if necessary, as provided in Section 2.1 of
the Merger Agreement. There were 8,381,193 shares of XcelleNet Common Stock
outstanding on April 16, 1998.

     
     The Merger Agreement contains customary representations and warranties of
the parties, which will not survive the effectiveness of the Merger.  In
addition, pursuant to the Merger Agreement, XcelleNet has agreed to operate its
business in the ordinary course pending consummation of the Merger, and
XcelleNet has agreed not to solicit negotiations 

                                      -2-
<PAGE>
 
or agreements relating to a competing business combination transaction. The
Merger is conditioned upon, among other things, (i) the approval of the holders
of at least a majority of the outstanding shares of XcelleNet Common Stock, (ii)
the termination or expiration of the waiting period pursuant to the Hart-Scott
Rodino Antitrust Improvements Act of 1976, as amended, and (iii) the receipt of
opinions of counsel by each of XcelleNet and Sterling to the effect that the
Merger will be treated for federal income tax purposes as a reorganization
within the meaning of Section 368(a) of the Internal Revenue Code of 1986, as
amended (the "Code"), and that no gain or loss will be recognized by the
shareholders of XcelleNet upon their exchange of shares for the Merger
Consideration under Section 354 of the Code (except to the extent that such
shareholders receive cash for their shares). Subject to the payment of certain
termination fees, both XcelleNet and Sterling may terminate the Merger Agreement
in certain specified circumstances. Either party may terminate the Merger
Agreement if the Merger is not consummated on or prior to October 31, 1998.

     In connection with the Merger Agreement, Dennis M. Crumpler (the Chairman
and Chief Executive Officer of XcelleNet), Maleah Crumpler and The Crumpler
Investment Limited Partnership (together, the "Crumpler Shareholders") entered
into a Shareholder Agreement, dated as of April 16, 1998, (the "Shareholder
Agreement") with Sterling. Pursuant to the Shareholder Agreement, the Crumpler
Shareholders (who own collectively 16.6% of the outstanding XcelleNet Common
Stock as of the date of the Merger Agreement) have agreed to vote, and have
granted an irrevocable proxy with respect to, their shares of XcelleNet Common
Stock in favor of approval of the Merger and the adoption of the Merger
Agreement and all transactions contemplated thereby, at a special meeting of
XcelleNet's shareholders. The Crumpler Shareholders also agreed, except pursuant
to the Merger Agreement, not to dispose of any shares of XcelleNet Common Stock
or to enter into any contract or arrangement to dispose of any shares of
XcelleNet Common Stock, and, except pursuant to the Shareholder Agreement, not
to grant any proxy or power of attorney with respect thereto with respect to
such shares.

     The Crumpler Shareholders also agreed to certain restrictions on their
transfer of shares of Sterling Common Stock received in the Merger.  The
Shareholder Agreement will automatically terminate upon the earlier of (i) the
termination of the Merger Agreement pursuant to the terms thereof or (ii) the
effective time of the Merger (except for the provisions relating to the
representations and warranties of, and post-Merger share transfer restrictions
on the Crumpler Shareholders, which provisions shall survive the effective time
of the Merger).

     Prior to the execution and delivery of the Merger Agreement and
the Shareholder Agreement, XcelleNet amended its Shareholder Protection Rights
Agreement, dated November 21, 1997 ("Amendment No. 1 to Rights Agreement"), such
that the execution and delivery of, and the consummation of the transactions
contemplated by, the Merger Agreement and the ancillary agreements thereto,
including, without limitation, the Shareholder Agreement, would not (i) result
in Sterling or Sub or any of their respective Affiliates or Associates being an
Acquiring Person, a Beneficial Owner or a Flip-Over Entity, (ii) result in the
occurrence of a Flip-In Date, a Stock Acquisition Date, a Separation Time, a
Flip-Over Transaction or Event, or (iii) in any other way effect any change or
modification of the terms of the Rights or the rights of the holders thereof,
including, without limitation, the Rights becoming exercisable. In addition,
pursuant to the terms of Amendment No. 1 to Rights Agreement, the Expiration
Time for the Rights will occur immediately prior to the effective time of the
Merger. For purposes hereof, the terms "Acquiring Person," "Affiliate,"
"Associate," "Beneficial Owner," "Expiration Time," "Flip-In Date," "Separation
Time," "Stock
                                      -3-
<PAGE>
 
Acquisition Date," "Flip-Over Entity," "Flip-Over Transaction or Event," and
"Rights" shall have the respective meanings ascribed thereto in the Shareholder
Protection Rights Agreement.

     The Merger Agreement, the Shareholder Agreement and Amendment No. 1 to
Rights Agreement are attached hereto as Exhibits 2.1, 99.1 and 4.1,
respectively, and are incorporated herein by reference.  The foregoing
descriptions of such documents are qualified in their entirety by reference to

respective shareholders for Parent to acquire Company, by means of a merger of
Company with and into Merger Sub (the "Merger"), on the terms and subject to the

     B.   Concurrently with the execution and delivery of this Agreement and as

agree as follows:
                                   ARTICLE I

                   -----------------------                                      
the Merger and without any action on the part of any holder of shares of
Company's common stock, par value $0.01 per share (individually a "Share" and
collectively the "Shares"), or any other capital stock of Company or any shares
of capital stock of Merger Sub:

                                       2
<PAGE>
 
          (a) Common Stock of Merger Sub.  Each share of common stock, par value
              --------------------------                                        
$0.01 per share, of Merger Sub issued and outstanding immediately prior to the
Effective Time shall remain outstanding.

          (b) Cancellation of Treasury Shares and Parent-Owned Shares.  Each
              -------------------------------------------------------       
Share issued and outstanding immediately prior to the Effective Time that is
owned by Company or any Subsidiary (as hereinafter defined) of Company or by
Parent, Merger Sub or any other Subsidiary of Parent (other than shares in trust
accounts, managed accounts, custodial accounts and the like that are
beneficially owned by third parties) shall automatically be canceled and retired
and shall cease to exist, and no consideration shall be delivered or deliverable
in exchange therefor.

          (c) Conversion of Shares.  Each Share issued and outstanding
              --------------------                                    
immediately prior to the Effective Time (other than Shares to be canceled in
accordance with Section 2.1(b) and any Dissenting Shares (as hereinafter
defined)) shall be converted into the right to receive the Merger Consideration
(as hereinafter defined) upon surrender of the certificate formerly representing
such Share in accordance with this Agreement.

          (d) Merger Consideration.  "Merger Consideration" shall mean, (i) a
              --------------------                                           
cash payment in an amount equal to $8.80 (the "Cash Payment") and (ii) 0.2885
(the "Stock Factor") of a fully paid and nonassessable share of Parent's common
stock, $0.01 par value per share ("Parent Common Stock"), adjusted, if
necessary, pursuant to the following paragraph.

          Notwithstanding the foregoing, in the event that the aggregate amount
of the Cash Payments, plus the dollar value of all Dissenting Shares (determined
as provided in this Section 2.1(d)), exceeds the value of all shares of Parent
Common Stock to be issued pursuant to Section 2.1(c) (based upon the closing
sales price of the Parent Common Stock on the last trading day prior to the
Closing Date), the Merger Consideration shall be adjusted by reducing the Cash
Payment and increasing the aggregate number of Shares of Parent Common Stock to
be issued pursuant to Section 2.1(c) in each case, to the minimum extent
necessary, such that the dollar amount of the aggregate Cash Payments plus the
dollar value of all Dissenting Shares (determined as provided in this Section
2.1(d)) is equal to the value of all shares of Parent Common Stock to be issued
(based upon the closing sales price of the Parent Common Stock on the last
trading day prior to the Closing Date).  In determining the adjustment pursuant
to the previous sentence, to the extent the Cash Payment is reduced, the number
of shares of Parent Common Stock shall be increased, dollar for dollar, valuing
the Parent Common Stock as the lesser of (i) the closing sales price of the
Parent Common Stock on the last trading day prior to the Closing Date, and (ii)
the average of the closing sales prices of Parent Common Stock for the three
trading days prior to the Closing Date.  For the purposes of this Section 2.1(d)
only, the value of each Dissenting Share shall be deemed to be an amount equal
to $22.

          The Stock Factor shall be adjusted to reflect fully the effect of any
stock split, reverse split, stock dividend (including any dividend or
distribution of securities convertible into Common Stock (as hereinafter
defined) or Parent Common Stock), reorganization, recapitalization or other like
change with respect to the Common Stock or the Parent Common Stock occurring
after the date hereof and on or prior to the Effective Time.

          (e) Dissenting Shares.  Notwithstanding anything in this Agreement to
              -----------------                                                
the contrary, any Shares issued and outstanding immediately prior to the
Effective Time held by a holder who has the right to demand, and who properly
demands, payment for such Shares ("Dissenting Shares") in accordance with
Article 13 of the GBCC (together with any successor provision, "Article 13")
shall not be converted into a right to receive the Merger Consideration, unless
such holder fails to perfect or otherwise loses such holder's right to payment
in accordance with Article 13.  If, after the Effective Time, such holder fails
to perfect or loses any such right, each such Share of such holder shall be
treated as a Share that had been converted as of the Effective Time into the
right to receive the Merger Consideration in accordance with this Section 2.1.
At the Effective Time, any holder of Dissenting Shares shall cease to have any
rights with respect thereto, except the rights provided in Article 13 and as
provided in the immediately preceding sentence.  Company shall give prompt
notice to Parent of any demands received by Company for payment in accordance
with Article 13, and Parent shall have the right to participate in and direct
all negotiations and proceedings with respect to such demands.  Company shall
not, except with the prior written consent of Parent, make any payment with
respect to, or settle or offer to settle, any such demands.

      SECTION 2.2  Stock Options.
                   ------------- 

          (a) At the Effective Time, each then-outstanding option to purchase
Shares (collectively, "Options") under Company's 1987 Stock Option Plan, as
amended, Company's 1994 Stock Option Plan for Outside Directors, as amended,
Company's 1996 Long-Term Incentive Plan and issued on an individual basis and
not under a plan (collectively, the "Stock Option Plans") shall be assumed by
Parent and shall constitute an option (a "Substitute Option") to acquire, on
substantially the same terms and subject to substantially the same conditions as
were applicable under such Option, including without limitation term, vesting,
exercisability, status as an "incentive stock option" under Section 422 of the
Internal Revenue Code of 1986, as amended (the "Code"), and termination
provisions, the number of shares of Parent Common Stock, rounded down to the
nearest whole share, determined by multiplying the number of Shares subject to
such Option immediately prior to the Effective Time by 0.4809 (the "Option
Conversion Factor") at an exercise price per share of Parent Common Stock
(increased to the nearest whole cent) equal to the exercise price per share of
Common Stock subject to such Option divided by the Option Conversion Factor;
provided, however, that in the case of any Option to which Section 421 of the
Code applies by reason of its qualification as an incentive stock option under
Section 422 of the Code, the conversion formula shall be adjusted if necessary
to comply with Section 424(a) of the Code.

          (b) Company shall use its best efforts to obtain all necessary
waivers, consents or releases from holders of Options under the Stock Option
Plans and take any such other action as may be reasonably necessary to give
effect to the transactions contemplated by this Section 2.2.

          (c) Parent shall take all corporate action necessary to reserve for
issuance a sufficient number of shares of Parent Common Stock for delivery upon
exercise of Substitute Options pursuant to the terms set forth in Section
2.2(a).  As soon as practicable after the Effective Time, Parent shall use
reasonable efforts to file and cause to be declared effective a registration
statement on Form S-8 (or any successor form) or another appropriate form to

                                       4
<PAGE>
 
register the shares of Parent Common Stock subject to Substitute Options and
Parent shall use reasonable efforts to maintain the effectiveness of such
registration statements for so long as the Substitute Options remain
outstanding.  In addition, Parent shall use reasonable efforts to cause the
shares of Parent Common Stock subject to Substitute Options to be listed on the
NYSE (as hereinafter defined) and such other exchanges as Parent shall
determine.

      SECTION 2.3  Share Purchase Rights.  Each reference in this Article II and
                   ---------------------                                        
in Article III to a "Share" is a reference to such Share together with the
Rights (as hereinafter defined in Section 4.1(c)), if any, associated with such
Share.


                                  ARTICLE III

                               PAYMENT FOR SHARES

      SECTION 3.1  Payment For Shares.
                   ------------------ 

          (a) Payment Fund.  Concurrently with the Effective Time, Parent shall
              ------------                                                     
deposit, or shall cause to be deposited, with or for the account of BankBoston,
N.A. or such other bank or trust company designated by Parent reasonably
satisfactory to Company (the "Paying Agent") for the benefit of the holders of
Shares (i) shares of Parent Common Stock representing the aggregate stock
portion of the Merger Consideration and (ii) cash in an aggregate amount
sufficient to pay the aggregate cash portion of the Merger Consideration
(hereinafter collectively referred to as the "Payment Fund").

          (b) Letters of Transmittal; Surrender of Certificates.  As soon as
              -------------------------------------------------             
reasonably practicable after the Effective Time, Parent shall instruct the
Paying Agent to mail to each holder of record (other than Company or any of its
Subsidiaries or Parent, Merger Sub or any of their respective Subsidiaries) of a
certificate or certificates that, immediately prior to the Effective Time,
evidenced outstanding Shares (the "Certificates"), (i) a form of letter of
transmittal (which shall specify that delivery shall be effected, and risk of
loss and title to the Certificates shall pass, only upon proper delivery of the
Certificates to the Paying Agent, and shall be in such form and have such other
provisions as Parent may reasonably specify) and (ii) instructions for use in
effecting the surrender of the Certificates in exchange for payment therefor.
Upon surrender of a Certificate for cancellation to the Paying Agent together
with such letter of transmittal, duly executed, and such other customary
documents as may be required pursuant to such instructions, the holder of such
Certificate shall be entitled to receive in respect thereof (A) a certificate
representing the number of whole shares of Parent Common Stock (and cash in lieu
of fractional shares of Parent Common Stock as contemplated by this Section 3.1)
that the aggregate number of Shares previously represented by such certificate
or certificates so surrendered shall have been converted into the right to
receive pursuant to Section 2.1(c) and (B) cash in an amount equal to the
product of (1) the number of Shares theretofore represented by such Certificate
and (2) the Cash Payment, and the Certificate so surrendered shall forthwith be
canceled. No interest shall be paid or accrued on the Merger Consideration
payable upon the surrender of any Certificate. If payment is to be made to a
person other than the person in whose name the surrendered Certificate is
registered, it shall be a condition of payment that the Certificate so
surrendered shall

                                       5
<PAGE>
 
be promptly endorsed or otherwise in proper form for transfer and that the
person requesting such payment shall pay any transfer or other taxes required by
reason of the payment to a person other than the registered holder of the
surrendered Certificate or established to the satisfaction of Parent and the
Surviving Corporation that such tax has been paid or is not applicable.

          (c) Cancellation and Retirement of Shares; No Further Rights.  As of
              --------------------------------------------------------        
the Effective Time, all Shares (other than Shares to be canceled in accordance
with Section 2.1(b) and any Dissenting Shares) issued and outstanding
immediately prior to the Effective Time shall cease to be outstanding and shall
automatically be canceled and retired and shall cease to exist, and each holder
of a Certificate theretofore representing any such Shares shall cease to have
any rights with respect thereto (including, without limitation, the right to
vote), except the right to receive the Merger Consideration, without interest,
upon surrender of such Certificate in accordance with this Article III, and
until so surrendered, each such Certificate shall represent for all purposes
only the right, subject to Section 2.1(e),  to receive the Merger Consideration,
without interest.  The Merger Consideration paid upon the surrender for exchange
of Certificates in accordance with the terms of this Article III shall be deemed
to have been paid in full satisfaction of all rights pertaining to the Shares
theretofore represented by such Certificates.

          (d) Distributions with Respect to Unsurrendered Shares.  No dividends
              --------------------------------------------------               
or other distributions with respect to Parent Common Stock with a record date
after the Effective Time shall be paid to the holder of any unsurrendered
Certificate with respect to the Shares represented thereby, and no cash payment
in lieu of fractional shares shall be paid to any such holder pursuant to
Section 3.1(e), and all such dividends, other distributions and cash in lieu of
fractional shares shall be paid by Parent to the Paying Agent and shall be
included in the Payment Fund, in each case until the surrender of such
Certificate in accordance with this Article III. Subject to the effect of
applicable escheat or similar Laws, following surrender of any such Certificate
there shall be paid to the holder of the certificate representing shares of
Parent Common Stock issued in exchange therefor, without interest, (i) at the
time of such surrender, the amount of dividends or other distributions with a
record date after the Effective Time theretofore paid with respect to such
shares of Parent Common Stock, and the amount of any cash payable in lieu of
fractional shares to which such holder is entitled pursuant to Section 3.1(e)
and (ii) at the appropriate payment date, the amount of dividends or other
distributions with a record date after the Effective Time but prior to such
surrender and with a payment date subsequent to such surrender payable with
respect to such shares of Parent Common Stock.

          (e)  No Fractional Shares.
               -------------------- 

               (i)  No certificates or scrip representing fractional shares of
Parent Common Stock shall be issued upon the surrender for exchange of
certificates that immediately prior to the Effective Time represented Shares
which have been converted pursuant to Section 2.1(c), and such fractional share
interests will not entitle the owner thereof to vote or to any rights of a
stockholder of Parent.

               (ii) In lieu of any such fractional shares, each holder of Shares
who would otherwise have been entitled to a fraction of a share of Parent Common
Stock upon surrender of Certificates for exchange pursuant to this Section 3.1
will be paid an amount in cash 

                                       6
<PAGE>
 
(without interest), rounded to the nearest cent, determined by multiplying (A)
the per share closing price on the NYSE of Parent Common Stock (as reported on
the NYSE Composite Transactions List) on the date on which the Effective Time
occurs (or, if Parent Common Stock does not trade on the NYSE on such date, the
first date of trading of Parent Common Stock on the NYSE after the Effective
Time) by (B) the fractional interest to which such holder otherwise would be
entitled. Promptly upon request from the Paying Agent, Parent will make
available to the Paying Agent the cash necessary for this purpose.

          (f) Investment of Payment Fund.  The Paying Agent shall invest the
              --------------------------                                    
cash portion of the Payment Fund as directed by Parent, in (i) direct
obligations of the United States of America, (ii) obligations for which the full
faith and credit of the United States of America is pledged to provide for the
payment of principal and interest, (iii) commercial paper rated the highest
quality by either Moody's Investors Services, Inc. or Standard & Poor's
Corporation, or (iv) certificates of deposit, bank repurchase agreements or
bankers' acceptances of commercial banks with capital exceeding $500 million.
Any net earnings with respect to the Payment Fund shall be the property of and
paid over to Parent as and when requested by Parent; provided, however, that any
such investment or any such payment of earnings shall not delay the receipt by
holders of Certificates of the Merger Consideration.

          (g) Termination of Payment Fund.  Any portion of the Payment Fund
              ---------------------------                                  
which remains undistributed to the holders of Certificates for 180 days after
the Effective Time shall be delivered to Parent, upon demand, and any holders of
Certificates that have not theretofore complied with this Article III shall
thereafter look only to Parent, and only as general creditors thereof, for
payment of their claim for any Merger Consideration.

          (h) No Liability.  None of Parent, Merger Sub, the Surviving
              ------------                                            
Corporation or the Paying Agent shall be liable to any person in respect of any
payments or distributions payable from the Payment Fund delivered to a public
official pursuant to any applicable abandoned property, escheat or similar Law.
If any Certificates shall not have been surrendered prior to five years after
the Effective Time (or immediately prior to such earlier date on which any
Merger Consideration in respect of such Certificate would otherwise escheat to
or become the property of any Governmental Entity (as hereinafter defined)), any
amounts payable in respect of such Certificate shall, to the extent permitted by
applicable Law, become the property of the Surviving Corporation, free and clear
of all claims or interest of any person previously entitled thereto.

          (i) Withholding Rights.  Parent shall be entitled to deduct and
              ------------------                                         
withhold, or cause to be deducted or withheld, from the consideration otherwise
payable pursuant to this Agreement to any holder of Shares, Options or
Certificates such amounts as are required to be deducted and withheld with
respect to the making of such payment under the Code, or any provision of
applicable state, local or foreign tax law.  To the extent that amounts are so
withheld, such withheld amounts shall be treated for all purposes of this
Agreement as having been paid to such holders in respect of which such deduction
and withholding was made.

          (j) Lost Certificates.  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, if required by
the Surviving Corporation, the posting by such 

                                       7
<PAGE>
 
person of a bond in such reasonable amount as the Surviving Corporation may
direct as indemnity against any claim that may be made against it with respect
to such Certificate, the Paying Agent will issue in exchange for such lost,
stolen or destroyed Certificate the Merger Consideration and, if applicable, any
cash in lieu of fractional shares, and unpaid dividends and distributions on
Shares deliverable in respect thereof, pursuant to this Agreement.

                                   ARTICLE IV

      SECTION 4.1  Representations and Warranties of Company.  Company
                   -----------------------------------------          
represents and warrants to Parent and Merger Sub as follows:

          (a) Organization, Standing and Corporate Power.  Each of Company and

qualified or licensed to do business and is in good standing in each
jurisdiction in which the nature of its business or the ownership or leasing of
its properties makes such qualification or licensing necessary, other than in
such jurisdictions where the failure to be so qualified or licensed could not
reasonably be expected to have, individually or in the aggregate, a Material
Adverse Effect (as hereinafter defined) on Company.  Company has delivered to
Parent true, complete and correct copies of the articles of incorporation and
bylaws or comparable governing documents of Company and each Subsidiary of
Company, in each case as amended to the date of this Agreement.  A true, correct

Section 4.1(a) of the Disclosure Memorandum.  Each of the outstanding shares of
capital stock of each of Company's Subsidiaries is duly authorized, validly
issued, fully paid and nonassessable (or, in the case of foreign Subsidiaries,

nonassessable), and except as set forth in Section 4.1(a) of the Disclosure
Memorandum is owned, directly or indirectly, by Company free and clear of all
Liens (as hereinafter defined). Except as set forth in Section 4.1(a) of the
Disclosure Memorandum, neither Company nor any of its Subsidiaries owns directly

of business).

          (b) Authority; Noncontravention.  Company has all necessary corporate
              ---------------------------

this Agreement by Company and the consummation by Company of the transactions
contemplated hereby have been duly authorized by all necessary corporate action
on the part of Company, subject, in the case of the Merger, to the approval of
this Agreement by its shareholders as contemplated by Section 6.2. This
Agreement has been duly executed and delivered by Company and, assuming this
Agreement constitutes the valid and 

                                       8
<PAGE>
 
binding agreement of Parent and Merger Sub, constitutes a valid and binding
obligation of Company, enforceable against Company in accordance with its terms.
Except as specified in Section 4.1(b) of the Disclosure Memorandum, the
execution and delivery of this Agreement do not, and the consummation of the

hereof will not, (i) conflict with any of the provisions of the articles of
incorporation or bylaws of Company or the comparable documents of any Subsidiary
of Company, (ii) subject to the governmental filings and other matters referred

of any obligation or a loss of a material benefit under, or require the consent
of any person under, any indenture or other agreement, permit, concession,
franchise, license or similar instrument or undertaking to which Company or any
of its Subsidiaries is a party or by which Company or any of its Subsidiaries or
any of their respective assets is bound or affected, or (iii) subject to the
governmental filings and other matters referred to in the next following
sentence, contravene any applicable Law currently in effect, which, in the case
of clauses (ii) and (iii) above could reasonably be expected to have,
individually or in the aggregate, a Material Adverse Effect on Company. No
consent, approval or authorization of, or declaration or filing with, or notice
to, any Governmental Entity (as hereinafter defined) which has not been received
or made is required by or with respect to Company or any of its Subsidiaries in
connection with the execution and delivery of this Agreement by Company or the
consummation by Company of the transactions contemplated hereby, except for (i)

Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended (the "HSR

          (c) Capital Structure.  The authorized capital stock of Company
              -----------------                                          
consists of (i) 30,000,000 shares of common stock, par value $0.01 per share
(the "Common Stock") and (ii) 10,000,000 shares of Preferred Stock, par value
$0.01 per share ("Preferred Stock"), of which 250,000 shares are designated

immediately preceding sentence, at the close of business on April 15, 1998, no

issuance or outstanding.  All outstanding shares of capital stock of Company are
duly authorized, validly issued, fully paid and nonassessable and not subject to
preemptive rights. Except as specified above or in Section 4.1(c) of the
Disclosure Memorandum, neither Company nor any Subsidiary of Company has or, at
or after the Effective Time will have, any outstanding option, warrant, call,
subscription or other right, agreement or commitment which (i) obligates Company
or any Subsidiary of Company to issue, sell or transfer, or repurchase, redeem
or otherwise acquire, any shares of the capital stock of Company or any
Subsidiary of Company, (ii) restricts the transfer of any shares of capital
stock of Company or any of its Subsidiaries, or (iii) relates to the voting of

of pre-2000 dates currently stored as two-digit dates. Section 4.1(h)(iv) of the
Disclosure Memorandum sets forth a true, correct and complete list of any
current developments or maintenance efforts with respect to the Owned Software,
including without limitation the development of new computer programs,
enhancements or revisions to existing computer programs included in the Owned

application for registration covering any of the Scheduled Intellectual Property
which is registered with, or in respect of which any application for

necessary to authorize this Agreement or to consummate the transactions
contemplated hereby.  This Agree  ment has been duly executed and delivered by

governmental filings and other matters referred to in the next following
sentence, conflict with, result in a breach of or default (with or without

of a material benefit under, or require the consent of any person under, any
indenture, or other agreement, permit, concession, franchise, license or similar
instrument or undertaking to which Parent or Merger Sub is a party or by which

the Form S-4, and Company shall file with the SEC, as soon as practicable after
the date hereof, a proxy statement (the "Proxy Statement") relating to the
Merger in accordance with the Exchange Act and the rules and regulations under

declared effective by the SEC.

               (ii)   Parent shall prepare and file with the SEC, as soon as
practicable after the date hereof, the Form S-4.  Each of Company and Parent
shall use all reasonable efforts to have the Form S-4 declared effective under
the Securities Act as promptly as practicable after such filing.  Parent also
shall take any action (other than qualifying to do business in any jurisdiction
in which it is not now so qualified or filing a general consent to service of
process) required to be taken under any applicable state securities laws in
connection with the issuance of Parent Common Stock in the Merger, and Company
shall furnish all information concerning Company and the holders of the Shares
as may be reasonably requested in connection with any such action.

convene a meeting of the shareholders of Company (the "Share  holders Meeting")
as promptly as practicable after the Form S-4 is declared effective by the SEC
for the purpose of considering and voting upon this Agreement.  Subject to
Company's right to terminate this Agreement pursuant to Section 8.1 and subject
to the Board of Directors of Company determining in good faith that the making
of such recommendation or the failure to withdraw such recommendation would
constitute a breach of fiduciary duties of the members of the Board of Directors
of Company under applicable Law, the Board of Directors of Company 

                                       28

Sub shall vote any Shares beneficially owned by them in favor of the approval of
this Agreement.

      SECTION 6.3  Access to Information; Confidentiality.  Company shall, and
                   --------------------------------------                     
shall cause each of its Subsidiaries to, afford to Parent and to Parent's
officers, employees, counsel, financial advisors and other representatives
reasonable access during normal business hours during the period prior to the
Effective Time to all its properties, books, contracts, commitments, tax
returns, personnel and records and, during such period, Company shall, and shall
cause each of its Subsidiaries to, furnish as promptly as practicable to Parent
such information concerning its business, properties, financial condition,
operations and personnel as Parent may from time to time reasonably request,
provided that the foregoing action shall be reasonably related to the
transactions contemplated hereby (including, without limitation, the integration
of Company's business with Parent and its existing businesses) and shall not
interfere unnecessarily with normal operations.  Parent shall, and shall cause
each of its Subsidiaries to, afford to Company and to Company's officers,
employees, counsel, financial advisors and other representatives reasonable
access during normal business hours during the period prior to the Effective
Time to all its properties, books, contracts, commitments, tax returns,
personnel and records and during such period, Parent shall, and shall cause each
of its Subsidiaries to, furnish as promptly as practicable to Company such
information concerning its business, properties, financial condition, operations
and personnel as Company may from time to time reasonably request, provided that
the foregoing action shall be reasonably related to the transactions
contemplated hereby and shall not interfere unnecessarily with normal
operations.  Any such investigation by Parent or Company shall not affect the
representations or warranties contained in this Agreement.  Parent and Company
will hold, and will cause their respective directors, officers, partners,
employees, accountants, counsel, financial advisors and other representatives
and affiliates to hold, any non-public information obtained from the other party
in confidence to the extent required by, and in accordance with the provisions
of the letter agreements between Parent and Company with respect to
confidentiality and other matters.

      SECTION 6.4  Reasonable Best Efforts.  Subject to the terms and conditions
                   -----------------------                                      
set forth in this Agreement, each of the parties shall use its reasonable best
efforts to take, or cause to be taken, all actions, and do, or cause to be done,
and assist and cooperate with the other parties in doing, all things necessary,
proper or advisable to consummate and make effective, in the most expeditious
manner practicable, the Merger and the other transactions contemplated by this
Agreement, including the satisfaction of the respective conditions set forth in
Article VII, provided that nothing herein shall preclude any party from
exercising its rights under this Agreement.

      SECTION 6.5  Indemnification.
                   --------------- 

          (a) From and after the Effective Time, the Surviving Corporation shall
indemnify, defend and hold harmless each person who is now, or has been at any
time prior to the date hereof or who, with the consent of Parent, becomes prior
to the Effective Time, an officer or director of Company (each, an "Indemnified
Party") against all losses, claims, damages, costs, 

                                       29
<PAGE>
 
expenses (including reasonable costs of investigation and defense and reasonable
attorneys' fees and expenses), liabilities or judgments or amounts that are paid
in settlement with the approval of the indemnifying party (which approval shall
not be unreasonably withheld) of or in connection with any threatened or actual
Claim based in whole or in part on or arising in whole or in part out of the
fact that such person is or was a director or officer of Company whether
pertaining to any matter existing or occurring at or prior to the Effective Time
and whether asserted or claimed prior to, or at or after, the Effective Time
("Indemnified Liabilities"), including all Indemnified Liabilities based in
whole or in part on, or arising in whole or in part out of, or pertaining to
this Agreement or the transactions contemplated hereby, in each case, to the
fullest extent permitted under the GBCC and by Company's Articles of
Incorporation and Bylaws as in effect on the date hereof, including provisions
relating to advances of expenses incurred in the defense of any matter and
whether or not Parent or the Surviving Corporation is insured against any such
matter. Without limiting the foregoing, in any case in which approval by the
Surviving Corporation is required to effectuate any indemnification, the
Surviving Corporation shall direct, at the election of the Indemnified Party,
that the determination of any such approval shall be made by independent counsel
mutually agreed upon by Parent and the Indemnified Party.

          (b) Without limiting the foregoing, in the event any such Claim is
brought against any Indemnified Party, whether arising before or after the
Effective Time, the Surviving Corporation shall assume and direct all aspects of
the defense thereof, including settlement; the Surviving Corporation shall
retain and direct, and pay all fees and expenses of, counsel reasonably
satisfactory to such Indemnified Party, provided that if the Surviving
Corporation elects not to assume such defense or if counsel for the Indemnified
Party advises that there are substantive issues that raise conflicts of interest
between Parent or the Surviving Corporation and the Indemnified Party, the
Indemnified Party may retain counsel reasonably satisfactory to Parent, and the
Surviving Corporation shall pay all reasonable fees and expenses of such counsel
for the Indemnified Party promptly as statements therefor are received to the
extent not prohibited by applicable Law and upon receipt of any affirmation and
undertaking required by applicable Law. The Surviving Corporation shall be
obligated pursuant to this paragraph (b) to pay for only one firm of counsel for
all Indemnified Parties in any jurisdiction, except to the extent that, in the
opinion of counsel to an Indemnified Party, under applicable standards of
professional conduct, there exist conflicts of interest among such Indemnified
Parties that preclude one firm of counsel from representing the interests of all
such Indemnified Parties.  The Indemnified Party shall cooperate in the vigorous
defense of any such matter.  The Indemnified Party shall have a right to
participate in (but not control) the defense of any such matter with its own
counsel and at its own expense.  Neither Parent nor the Surviving Corporation
shall be liable for any settlement effected without its prior written consent,
which shall not be unreasonably withheld.  After the Effective Time neither
Parent nor the Surviving Corporation shall settle any such matter unless (i) the
Indemnified Party gives prior written consent, which shall not be unreasonably
withheld, or (ii) the terms of the settlement provide that the Indemnified Party
shall have no responsibility for the discharge of any settlement amount and
impose no other obligations or duties on the Indemnified Party and the
settlement discharges all rights against Indemnified Party with respect to such
matter.  Any Indemnified Party wishing to claim indemnification under this
Section 6.5, upon learning of any such claim, action, suit, proceeding or
investigation, shall notify Company (or, after the Effective Time, Parent and
the Surviving Corporation) (but the failure so to notify shall 

                                       30
<PAGE>
 
not relieve a party from any liability which it may have under this Section 6.5
except to the extent such failure prejudices such party).

          (c) If Parent or the Surviving Corporation or any successors or
assigns shall consolidate with or merge into any other person and shall not be
the continuing or surviving person in such consolidation or merger, or shall
transfer all or substantially all of its assets to any person, then and in each
case, provision shall be made so that the successors and assigns of Parent or
the Surviving Corporation, as the case may be, shall assume the obligations set
forth in this Section 6.5.

          (d) Parent shall, or shall cause the Surviving Corporation to,
purchase policies of directors' and officers' "run-off" liability insurance (or
policies that contain terms and conditions that are no less advantageous, in any
material respect, to the directors and officers and former directors and
officers of Company as the directors' and officers' liability insurance policies
that are in effect at Company on the date hereof), which insurance shall remain
in effect for a period of not less than three years from and after the Effective
Time; provided that the Surviving Corporation shall not be required to pay an
annual premium thereon in excess of the last annual premium paid prior to the
date hereof by Company on its current directors' and officers' insurance policy.

          (e) The provisions of this Section 6.5 shall survive the Effective
Time, are intended expressly to be for the benefit of, and shall be enforceable
by, each Indemnified Party and their respective heirs and representatives.
Parent hereby guarantees, for a period of seven years, the performance by the
Surviving Corporation of the indemnification obligations of the Surviving
Corporation pursuant to this Section 6.5; provided that, in the event that any
claim is asserted or made within such seven-year period, Parent's guarantee
shall continue in respect of any such claim until final disposition of such
claim.

      SECTION 6.6  Public Announcements.  Parent and Merger Sub, on the one
                   --------------------                                    
hand, and Company, on the other hand, shall consult with each other before
issuing, and provide each other the opportunity to review and comment upon, any
press release, SEC filing (including without limitation the Form S-4 and the
Proxy Statement) or other public statements with respect to the transactions
contemplated by this Agreement, including the Merger, and shall not issue any
such press release or make any such public statement prior to such consultation,
except (i) to the extent any party reasonably determines, after consultation
with its counsel, that disclosure is necessary or advisable in order to satisfy
such party's disclosure obligations under applicable Law, or (ii) as may be
required by court process or by obligations pursuant to any listing agreement
with any national securities exchange.

      SECTION 6.7  No Solicitation; Acquisition Proposals.
                   -------------------------------------- 

          (a) Until the termination of this Agreement in accordance with Section
8.1, Company shall not, and shall not authorize or permit any of its
Subsidiaries, or any of its or their affiliates, officers, directors, employees,
agents or representatives (including without limitation any investment banker,
financial advisor, attorney or accountant retained by Company or any of its
Subsidiaries), to, directly or indirectly, initiate, solicit or encourage
(including by way of furnishing information or assistance), or take any other
action to facilitate, any inquiries, any 

                                       31
<PAGE>
 
expression of interest or the making of any proposal that constitutes, or may
reasonably be expected to lead to, an Acquisition Proposal (as hereinafter
defined), or enter into or maintain or continue discussions or negotiate with
any person in furtherance of such inquiries or to obtain an Acquisition Proposal
or agree to or endorse any Acquisition Proposal; provided, however, that nothing
in this Agreement shall prohibit the Board of Directors of Company from (A)
furnishing information to, or entering into, maintaining or continuing
discussions or negotiations with, any person that makes an unsolicited
Acquisition Proposal after the date hereof or (B) recommending an Acquisition
Proposal to the shareholders of Company, if, and to the extent that, the Board
of Directors of Company, (i) determines in good faith that such Acquisition
Proposal would constitute a Superior Proposal (as hereinafter defined) and (ii)
determines in good faith (after consultation with outside legal counsel) that
such action is necessary for the Board of Directors of Company to comply with
its fiduciary duties under applicable Law, and, prior to furnishing any non-
public information to such person, Company receives from such person an executed
confidentiality agreement with provisions no less favorable to Company than the
letter agreement relating to the furnishing of confidential information of
Company to Parent referred to in the last sentence of Section 6.3. Company shall
promptly (and, in any event within 24 hours) notify Parent after receipt of any
Acquisition Proposal or any request for information relating to Company or any
of its Subsidiaries or for access to the properties, books or records of Company
or any of its Subsidiaries by any person who has informed Company that such
person is considering making, or has made, an Acquisition Proposal, and Company
shall keep Parent informed in reasonable detail of the status and details of any
such Acquisition Proposal.

          (b) For purposes of this Agreement, "Acquisition Proposal" means an
inquiry, offer or proposal regarding any of the following (other than the
transactions contemplated by this Agreement with Parent or Merger Sub) involving
Company:  (A) any merger, consolidation, share exchange, recapitalization,
business combination or other similar transaction; (B) any sale, lease,
exchange, mortgage, pledge, transfer or other disposition of all or
substantially all the assets of Company and its Subsidiaries, taken as a whole,
in a single transaction or series of related transactions; (C) any tender offer
or exchange offer for 20 percent or more of the outstanding shares of capital
stock of Company or the filing of a registration statement under the Securities
Act in connection therewith; or (D) any public announcement of a proposal, plan
or intention to do any of the foregoing or any agreement to engage in any of the
foregoing.  For purposes of this Agreement, "Superior Proposal" means any
Acquisition Proposal that Company's Board of Directors determines in its good
faith judgment (based on the advice of a financial advisor of nationally
recognized reputation) to be more favorable to Company's shareholders than the
Merger and for which financing, to the extent required, is then committed or
which, in the good faith judgment of Company's Board of Directors, is reasonably
capable of being obtained by such third party.

          (c) Nothing contained in this Section 6.7 shall prohibit Company from
taking and disclosing to its shareholders a position contemplated by Rule 14e-2
promulgated under the Exchange Act or from making any disclosure to Company's
shareholders which, in the good faith judgment of the Board of Directors of
Company based on the advice of outside counsel, is required under applicable
Law; provided that Company does not withdraw or modify, or propose to withdraw
or modify, its position with respect to the Merger or approve or recommend, or

                                       32
<PAGE>
 
propose to approve or recommend, an Acquisition Proposal unless Company and its
Board of Directors have complied with all the provisions of this Section 6.7.

      SECTION 6.8  Consents, Approvals and Filings.  Upon the terms and subject
                   -------------------------------                             
to the conditions hereof, each of the parties hereto shall (a) make promptly its
respective filings, and thereafter make any other required submissions, under
the HSR Act and the Exchange Act, with respect to the Merger and the other
transactions contemplated hereby and (b) use its reasonable efforts to take, or
cause to be taken, all appropriate action, and to do, or cause to be done, all
things necessary, proper or advisable under applicable Laws and regulations to
consummate and make effective the Merger and the other transactions contemplated
hereby, including without limitation using its reasonable efforts to obtain all
licenses, permits, consents, approvals, authorizations, qualifications and
orders of Governmental Entities and parties to contracts with Company and its
Subsidiaries as are necessary for the consummation of the Merger and the other
transactions contemplated hereby and to fulfill the conditions to the Merger;
provided, however, (i) that in no event shall Parent or any of its Subsidiaries
be required to agree or commit to divest, hold separate, offer for sale,
abandon, limit its operation of or take similar action with respect to any
assets (tangible or intangible) or any business interest of it or any of its
Subsidiaries (including without limitation the Surviving Corporation after
consummation of the Merger) in connection with or as a condition to receiving
the consent or approval of any Governmental Entity (including without limitation
under the HSR Act) and (ii) that nothing herein shall preclude any party from
exercising its rights under this Agreement.

      SECTION 6.9  Board Action Relating to Stock Option Plans and Stock
                   -----------------------------------------------------
Purchase Plan.
- ------------- 

          (a) As soon as practicable following the date of this Agreement, the
Board of Directors of Company (or, if appropriate, any committee administering a
Stock Option Plan) shall adopt such resolutions or take such actions, if any, as
may be required to adjust the terms of all outstanding Options in accordance
with Section 2.2 and shall make such other changes to the Stock Option Plans as
it deems appropriate to give effect to the Merger (subject to the approval of
Parent, which shall not be unreasonably withheld).  Notwithstanding the
foregoing or anything else in this Agreement to the contrary, except as
disclosed in Section 6.9(a) of the Disclosure Memorandum, Company shall not take
any action to accelerate the vesting, exercisability or other rights under any
Options granted under any Stock Option Plan.

          (b) Without limiting the generality or effect of Section 5.1, at the
written request of Parent, the Board of Directors of Company shall adopt such
resolutions or take such actions as may be required pursuant to the Stock
Purchase Plan such that no Option Period (as such term is defined in the Stock
Purchase Plan) will commence after the date hereof. Alternatively, at the
request of Parent, the Board of Directors of Company shall amend the Stock
Purchase Plan as reasonably requested by Parent, including to provide that the
next Option Period will expire at or immediately prior to the Effective Time.

      SECTION 6.10 Employment and Employee Benefit Matters.
                   --------------------------------------- 

          (a) Each of Parent, Merger Sub and Company will take the actions
indicated to be taken by it in Section 6.10(a) of the Disclosure Memorandum at
or prior to the time specified therein.  Following the Effective Time, Parent
shall cause the Surviving Corporation and its Subsidiaries to honor in
accordance with their terms all employment, severance, consulting and other
compensation contracts disclosed in Section 6.10(a) of the Disclosure Memorandum
between Company or any of its Subsidiaries and any current or former director,
officer or employee thereof, and all provisions for vested benefits or other
vested amounts earned or accrued through the Effective Time under the Company
Plans, to the extent it does not constitute a violation of this Agreement.

          (b) As promptly as practicable, following the Effective Time, Parent
shall cause to be provided generally to officers and employees of Company and
its Subsidiaries employee benefits under employee benefit and welfare plans
(other than stock option or other plans involving the potential issuance of
Parent Common Stock), on terms and conditions which when taken as a whole are
substantially similar to those currently provided by Parent to their similarly
situated officers and employees; provided, that, for a period of 12 months after
the Effective Time, Parent shall provide generally to officers and employees of
Company and its Subsidiaries (other than those persons who currently have
written severance agreements with Company) severance benefits in accordance with
the policies of either (i) Company as disclosed in Section 6.10(b) of the
Disclosure Memorandum, or (ii) Parent, whichever of (i) or (ii) will provide the
greater benefit to the officer or employee.  For purposes of participation,
vesting and (except in the case of Parent retirement and sabbatical plans)
benefit accrual under Parent's employee benefit plans, the service of the
employees of Company and its Subsidiaries prior to the Effective Time shall be
treated as service with Parent participating in such employee benefit plans.

      SECTION 6.11 Affiliates and Certain Shareholders. At least three business
                   -----------------------------------                         
days prior to the Closing Date, Company shall deliver to Parent a letter
identifying all persons whom it reasonably believes are "affiliates" of Company
for purposes of Rule 145 under the Securities Act. Company shall use its
reasonable efforts to cause each such person to deliver to Parent on or prior to
the Closing Date a written agreement substantially in the form attached as
Exhibit A hereto. Parent shall not be required to maintain the effectiveness of
the Form S-4 or any other registration statement under the Securities Act for
the purposes of resale of Parent Common Stock by such affiliates, and the
certificates representing Parent Common Stock received by such affiliates in the
Merger shall bear a customary legend regarding applicable Securities Act
restrictions.

      SECTION 6.12 NYSE Listing. Parent shall use its reasonable efforts to
                   ------------                                            
cause the shares of Parent Common Stock to be issued in the Merger to be
approved for listing on the NYSE, subject to official notice of issuance, prior

                                                                       ---------

                          FORM OF AFFILIATE AGREEMENT

Gentlemen:

     The undersigned is a holder of shares of common stock, par value $.01 per
share ("Company Common Stock"), of XcelleNet, Inc., a Georgia corporation
("Company"), or may become a holder of shares of Company Common Stock prior to
the effective time of the Merger (as hereinafter defined) upon exercise of
certain options held by the undersigned to purchase shares of Company Common
Stock.  As such, the undersigned will be entitled to receive in connection with
the merger (the "Merger") of Company with and into Sterling Commerce (Southern),
Inc., a Delaware corporation and a subsidiary of Sterling Commerce, Inc., a
Delaware corporation ("Parent"), shares of common stock, par value $.01 per
share, of Parent (the "Securities") in exchange for any such shares of Company
Common Stock held by the undersigned at the effective time of the Merger.

     The undersigned acknowledges that the undersigned may be deemed an
"affiliate" of Company within the meaning of Rule 145 ("Rule 145") promulgated
under the Securities Act of 1933, as amended (the "Act") of the Securities and
Exchange Commission (the "Commission"), although nothing contained herein shall
be construed as an admission of such status.

     If in fact the undersigned were an affiliate of Company under the Act, the
undersigned's ability to sell, assign or transfer any Securities received by the
undersigned in exchange for any shares of Company Common Stock pursuant to the
Merger may be restricted unless such transaction is registered under the Act or
an exemption from such registration is available.  The undersigned understands
that such exemptions are limited and the undersigned has obtained advice of
counsel as to the nature and conditions of such exemptions, including
instructions with respect to the applicability to the sale of such Securities of
Rules 144 and 145(d) promulgated under the Act.

     The undersigned hereby represents to and covenants to Parent that the
undersigned will not sell, assign or transfer any Securities received by the
undersigned in exchange for shares of Company Common Stock pursuant to the
Merger except (i) pursuant to an effective registration statement under the Act,
(ii) by a transaction in conformity with the volume and other limitations of
Rule 145 or Rule 144 under the Act ("Rule 144"), to the extent applicable, and
any other applicable rules promulgated by the Commission, or (iii) in a
transaction which, in the opinion of independent counsel reasonably satisfactory
to Parent, is not required to be registered under the Act.

     In the event of a sale of Securities pursuant to Rule 145, or, if
applicable, Rule 144, the undersigned will provide Parent with evidence of
compliance with such Rule, in the form of customary seller's or broker's Rule
145 or, if applicable, Rule 144, representation letters or as Parent may
otherwise reasonably request.  The undersigned understands that Parent may
instruct 
<PAGE>
 
its transfer agent to withhold the transfer of any Securities disposed of by the
undersigned in a manner inconsistent with this letter.

     The undersigned acknowledges and agrees that appropriate legends will be
placed on certificates representing Securities received by the undersigned in
the Merger or held by a transferee thereof, which legends will be removed (i) by
delivery of substitute certificates upon receipt of an opinion in form and
substance reasonably satisfactory to Parent to the effect that such legends are
no longer required for the purposes of the Act and the rules and regulations of
the Commission promulgated thereunder or (ii) in the event of a sale of the
Securities which has been registered under the Act.

     The undersigned acknowledges that it has carefully reviewed this letter and
understands the requirements hereof and the limitations imposed upon the
distribution, sale, transfer or other disposition of Securities.

                                    Very truly yours,


                                    ---------------------------------

Dated:______________, 1998

     As an inducement to the above individual to deliver this letter, Parent
agrees that for so long and to the extent necessary to permit such individual to
sell the Securities pursuant to Rule 145 and, to the extent applicable, Rule 144
under the Act, Parent shall use all reasonable efforts to file, on a timely
basis, all reports and data required to be filed by it with the Commission
pursuant to Section 13 of the Securities and Exchange Act of 1934.

                                    Very truly yours,

the date and time on which the Merger Agreement is terminated pursuant to and in
accordance with Section 8.1 thereof, are collectively referred to herein as such
Shareholder's "Subject Shares"). Except for Ms. Crumpler, who has entered into
an agreement with Mr. Crumpler with respect to the shares of Common Stock owned
by her, each Shareholder is entitled to dispose of (or to direct the disposition
of) and to vote (or to direct the voting of) the number of shares of Common

Shareholder has agreed, to enter into this Agreement.

Merger Agreement by written consent of shareholders of Company, each Shareholder
shall vote or cause to be voted (including by written consent, if applicable)
all of such Shareholder's Subject Shares in favor of the adoption of the Merger
Agreement and in favor of any other matter necessary for the consummation of the
transactions contemplated by the Merger Agreement and considered and voted upon
at such meeting or made the subject of such written consent, as applicable. At
any meeting of the shareholders of Company called to consider and vote upon any

by written consent of shareholders of Company, each Shareholder shall vote or
cause to be voted (including by written consent, if applicable) all of such

connection with the Merger shall constitute an Adverse Proposal. The
Shareholders' obligation to vote or cause to be voted the Subject Shares shall
be fully satisfied by the grant of the irrevocable proxy pursuant to Section 1.2
hereof, unless such Section shall have been judicially determined to be invalid
and unenforceable.

                                CERTAIN COVENANTS

         Section 3.1  Certain Covenants of Shareholders.

                  (a) Restriction on Transfer of Subject Shares, Proxies and
                      ------------------------------------------------------
Noninterference. No Shareholder shall directly or indirectly: (i) except
- ---------------
pursuant to the terms of this Agreement or the Merger Agreement, offer for sale,
sell, transfer, tender, pledge, encumber, assign or otherwise dispose of, or
enter into any contract, option or other arrangement or understanding with
respect to or consent to the offer for sale, sale, transfer, tender, pledge,
encumbrance, assignment or other disposition of, any or all of such
Shareholder's Subject Shares; (ii) except pursuant to the terms of this
Agreement, grant any proxies or powers of attorney, deposit any of such
Shareholder's Subject Shares into a voting trust or enter into a voting
agreement with respect to any of such Shareholder's Subject Shares; or (iii)
take any action that would make any representation or warranty contained herein
untrue or incorrect or have the effect of impairing the ability of such
Shareholder to perform such Shareholder's obligations under this Agreement.

                  (b) Restrictions on Transfer of Parent Common Stock. Following
                      -----------------------------------------------
the Effective Time and subject to the provisions of Section 3.1(c), no
Shareholder shall sell, assign or otherwise dispose of any of the shares of
Parent Common Stock received by such Shareholder pursuant to the Merger, as the
case may be, except (i) pursuant to an effective registration statement under
the Securities Act, (ii) in conformity with the provisions of SEC Rule 144 or
SEC Rule 145, as applicable, or (iii) in a transaction which, in the opinion of
counsel reasonably satisfactory to Parent, is not required to be registered
under the Securities Act. Each Shareholder understands and acknowledges that
Parent shall not be required to file or maintain the effectiveness of any
registration statement under the Securities Act for the purpose of facilitating
the resale of any Parent Common Stock by such Shareholder. In the event of a
sale, assignment or other disposition by any Shareholder of Parent Common Stock
pursuant to SEC Rule 145,


                                       -4-
<PAGE>
 
such Shareholder shall supply Parent with evidence of compliance with such Rule
as reasonably requested by Parent. Each Shareholder understands and acknowledges
that Parent may instruct its transfer agent to withhold the transfer of any
Parent Common Stock disposed of by any Shareholder, but that (provided such
transfer is not prohibited by any other provision of this Agreement) upon
receipt of such evidence of compliance, Parent shall cause the transfer agent to
effectuate the transfer of the Parent Common Stock sold as promptly as
practicable.

                  (c) Restrictions on Sale of Parent Company Stock.
                      --------------------------------------------
Notwithstanding anything contained in this Agreement to the contrary, prior to
the second anniversary of the Effective Time, the Shareholders shall not, in the
aggregate, sell, assign, transfer, pledge, encumber or otherwise dispose of, or
enter into any contract, option or other arrangement or understanding with
respect to or consent to the offer for sale, transfer, pledge, encumbrance,
assignment or other disposition of such number of shares of Parent Common Stock
representing more than 35% of the Merger Consideration received by the
Shareholders pursuant to the Merger. To determine the number of shares of Parent
Common Stock subject to restriction pursuant to this Section 3.1(c), the parties
(i) multiply the number of shares of Parent Common Stock received by the
Shareholders as part of the Merger Consideration by the closing sales price of
the Parent Common Stock on the day on which the Effective Time occurs, (ii) add
the aggregate Cash Payment received by the Shareholders as part of the Merger
Consideration, and (iii) divide the sum of the amounts determined in clauses (i)
and (ii) by the closing sales price of the Parent Common Stock on the date on
which the Effective Time occurs.

                  (d) Tax Treatment. No Shareholder shall or shall permit any
                      -------------
Shareholder Entity to take any position on any federal, state or local income
tax return, or take any other action or reporting position, that is inconsistent
with the treatment of the Merger as a reorganization within the meaning of
Section 368(a) of the Internal Revenue Code of 1986, as amended (the "Code"), or
with the representations made in this Agreement, unless otherwise required
pursuant to a "determination" (as defined in Section 1313(a)(1) of the Code).

                     -----------------
expenses incident to preparing for, entering into and carrying out this
Agreement and the consummation of the transactions contemplated hereby.

         Section 4.2 Amendment.  This Agreement may not be amended except by an
                     ---------
instrument in writing signed on behalf of each of the parties hereto.

         Section 4.3 Extension; Waiver. Any agreement on the part of a party to
                     -----------------
waive any provision of this Agreement, or to extend the time for any performance
hereunder, shall be valid only if set forth in an instrument in writing signed
on behalf of such party. The failure of any party to this Agreement to assert
any of its rights under this Agreement or otherwise shall not constitute a
waiver of such rights.

         Section 4.4 Legend. Each Shareholder acknowledges and agrees that the

Time, or upon (a) the earlier sale of such shares of Parent Common Stock (i)
pursuant to an effective registration statement under the Securities Act or (ii)
in conformity with the provisions of SEC Rule 144 or SEC Rule 145, as
applicable, or (b) the receipt by Parent of an opinion in form and substance
reasonably satisfactory to Parent from independent counsel reasonably
satisfactory to Parent to the effect that such legend is no longer required for
purposes of the Securities Act.
