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

     WHEREAS, NOVA, through its direct and indirect subsidiaries, is in the
business of providing credit card and debit card transaction processing services
and settlement services (including the related products and services of
automated teller machines and check guarantee services) to merchants, financial
institutions, independent sales organizations ("ISOs"), and other similar
customers (collectively, the "Business") throughout the United States (the
"Territory");

     WHEREAS, Employee currently serves as Chief Financial Officer of NOVA
pursuant to an Employment Agreement between Employee and NOVA effective May 24,
2000 (the "Prior Agreement");

     WHEREAS, NOVA and Employee desire to terminate the Prior Agreement, which
termination shall be contemporaneous with the effectiveness of this Agreement;

     WHEREAS, NOVA desires that Employee continue to work for NOVA, and Employee
desires to continue said employment, all as contemplated herein;

     NOW, THEREFORE, for and in consideration of his continued employment by
NOVA pursuant to this Agreement, the NOVA Confidential Information and Trade
Secrets (as hereafter defined) furnished to Employee by NOVA in order that he
may continue to perform his duties under this Agreement, the mutual covenants
and agreements herein contained, and other valuable consideration, the receipt
and sufficiency of which are hereby acknowledged, the parties hereto agree as
follows:

     1.   Employment of Employee. NOVA hereby employs Employee for a period
beginning as of the Effective Date and ending two (2) years thereafter (the
"Initial Term"), unless Employee's employment by NOVA is sooner terminated or
automatically renewed pursuant to the terms of this Agreement (Employee's
employment by NOVA pursuant to the terms of this Agreement shall hereinafter be
referred to as "Employment").

          (a)  Employee agrees to such Employment on the terms and conditions
     herein set forth and agrees to devote his reasonable best efforts to his
     duties under this Agreement and to perform such duties diligently and
     efficiently and in accordance with the directions of NOVA's Chief Executive
     Officer.

          (b)  During the term of Employee's Employment, Employee shall serve as
     Chief Financial Officer of NOVA.  Employee shall perform such duties as are
     assigned to him by NOVA's Chief Executive Officer, including but not
     limited to such duties as are customary for an officer in Employee's
     position.

                                       1
<PAGE>

          (c)  Employee shall devote substantially all of his business time,
     attention, and energies to NOVA's Business, shall act at all times in the
     best interests of NOVA, and shall not during the term of his Employment be
     engaged in any other business activity, whether or not such business is
     pursued for gain, profit, or other pecuniary advantage, or permit such
     personal interests as he may have to interfere with the performance of his
     duties hereunder. Notwithstanding the foregoing, Employee may participate
     in industry, civic and charitable activities so long as such activities do
     not materially interfere with the performance of his duties hereunder.

     2.   Compensation. During the term of Employee's Employment and in
accordance with the terms hereof, NOVA shall pay or otherwise provide to
Employee the following compensation:

          (a)  Employee's annual salary during the term of his Employment shall
     be Three Hundred Thousand and No/100 Dollars ($300,000.00) ("Base Salary").
     So long as this Agreement remains in effect, Employee's Base Salary shall
     be reviewed by NOVA's Chief Executive Officer in each fiscal year, within a
     reasonable time following the availability of NOVA's financial statements
     for the preceding fiscal year.  Following such review (or at any other
     time), NOVA may, in its sole and exclusive discretion, increase Employee's
     Base Salary.  The Base Salary shall be paid by NOVA in accordance with
     NOVA's regular payroll practice.

          (b)  In addition to the Base Salary, Employee shall be eligible to
     receive annual bonus compensation ("Bonus Compensation") in the amount, and
     on the terms and conditions described in the Annual Incentive Compensation
     Schedule attached as Exhibit A (the "Incentive Compensation Plan").  NOVA
                          ---------
     may, in its sole discretion, unilaterally modify Exhibit A on an annual
                                                      ---------
     basis.  Upon written request and subject to the terms and conditions set
     forth in this Section 2(b), Employee shall be entitled to elect to receive
     all or part of any Bonus Compensation payable to Employee under the
     Incentive Compensation Plan in shares of NOVA common stock, par value $.01
     per share ("NOVA Stock"), valued on the basis of the closing price of NOVA
     Stock on the New York Stock Exchange on the date of Employee's request (or
     if such date is not a trading day, on the immediately preceding trading
     day); provided, however, that NOVA shall not be obligated to comply with
     Employee's request if (i) NOVA does not have shares of NOVA Stock available
     for issuance or (ii) the issuance of NOVA Stock to Employee would be
     impracticable or impede, in any respect, NOVA's ongoing business
     operations.

          (c)  Under Section 2(c) of the Prior Agreement, NOVA granted Employee
     certain options and such options shall continue to vest pursuant to the
     terms set forth in the Prior Agreement.

          (d)  As an inducement for Employee to enter the Prior Agreement, NOVA
     paid Employee a special one time incentive of Seventy-Five Thousand and
     No/100 Dollars ($75,000) (the "Signing Bonus").  If Employee's employment
     with NOVA ends pursuant to Sections 6(b), 6(e), or 6(f) of this Agreement
     or if Employee otherwise voluntarily ends his employment with NOVA within
     twelve (12) months of the May 24, 2000, Employee will repay the Signing
     Bonus

                                       2
<PAGE>

     to NOVA. Employee's obligation to repay the Signing Bonus under this
     Section will be reduced by 1/12/th/ of the full amount for each full month
     of employment completed by Employee.

          (e)  To assist Employee's transition to NOVA, and subject to the
     approval of NOVA's Board of Directors, NOVA will loan employee up to Five
     Hundred Thousand and No/00 Dollars ($500,000.00).  The execution of a
     promissory note for the amount borrowed is an express condition precedent
     to NOVA's obligation to deliver any funds to Employee.  Any loan taken
     pursuant to this Section will be payable over five years or within 30 days
     of the end of Employee's employment with NOVA for any reason whatsoever,
     whichever is sooner.  Payment terms and frequency will be determined prior
     to the disbursement of any loan and will be set forth in the promissory
     note.  The interest rate on any loan under this Section shall be equal to
     NOVA's cost of funds plus ten (10) basis points.

          (f)  NOVA may withhold from any benefits payable under this Agreement
     all federal, state, city or other taxes as shall be required pursuant to
     any law or governmental regulation or ruling.

     3.   Benefits. During the term of Employee's employment, and for such time
thereafter as may be required by Section 7 hereof, NOVA shall provide to
Employee the following benefits and shall waive, to the extent possible, any
applicable waiting periods :

          (a)  Medical Insurance.  Employee and his dependents shall be entitled
               -----------------
     to participate in such medical, dental, vision, prescription drug,
     wellness, or other health care or medical coverage plans as may be
     established, offered or adopted from time to time by NOVA for the benefit
     of its employees and/or executive officers, pursuant to the terms set forth
     in such plans.

          (b)  Life Insurance.  Employee shall be entitled to participate in any
               --------------

     NOVA for the benefit of its employees and/or executive officers.

          (c)  Disability Insurance.  Employee shall be entitled to participate
               --------------------
     in any disability insurance plans established, offered, or adopted from
     time to time by NOVA for the benefit of its employees and/or executive
     officers.

          (d)  Vacations, Holidays.  Employee shall be entitled to at least four
               -------------------
     (4) weeks of paid vacation each year and all holidays observed by NOVA.

          (e)  Stock Option Plans.  Employee also shall be eligible for
               ------------------
     participation in any stock option plan or restricted stock plan adopted by
     NOVA's Board of Directors or the Compensation Committee which is applicable
     to NOVA's Executive Vice Presidents.

          (f)  Other Benefits.  In addition to and not in any way in limitation
               --------------

<PAGE>

     or purchase plans, and fringe benefits) on the same basis as such are
     afforded to other executive officers of NOVA during the term of this
     Agreement.

          (g)  Terms and Provisions of Plans. NOVA agrees that it shall not take
               -----------------------------
     action (during the term of this Agreement or the "Continuation Period," as
     defined in Section 7(a)) to modify the terms and provisions of any such
     plan or arrangement so as to exclude only Employee and/or his dependents,
     either by excluding Employee and/or his dependents explicitly by name or by
     modifying provisions generally applicable to all employees and dependents
     so that only Employee and/or his dependents would be affected.

          (h)  Vesting of Rights.  Upon the occurrence of a "Change in Control"
               -----------------
     (as defined in Section 7(f)) during the term of this Agreement, and
     regardless of whether Employee terminates this Agreement following such
     occurrence, and notwithstanding any provision to the contrary in any other
     agreement or document (including NOVA's applicable plan documents), all
     stock options, restricted stock, and other similar rights that have been
     granted to Employee and that are not vested on the date of occurrence of
     such an event, as well as any Deferred Compensation Plan balance that is
     not vested on the date of occurrence of such an event, shall become vested
     and exercisable immediately (collectively, the "Vested Rights").  As
     provided under the applicable plan or agreement, Employee shall have the
     right to exercise any or all of the Vested Rights.

     4.   Personnel Policies. Employee shall conduct himself at all times in a
businesslike and professional manner as appropriate for a person in his position

practices. In addition, Employee shall be subject to and abide by the policies
and procedures of NOVA applicable generally to personnel of NOVA, as adopted
from time to time.

     5.   Reimbursement for Business Expenses. Employee shall be reimbursed, on
no less frequently than a monthly basis, for all out-of-pocket business expenses
incurred by him in the performance of his duties hereunder, provided that
Employee shall first document and substantiate said business expenses in the
manner generally required by NOVA under its policies and procedures.

     6.   Term and Termination of Employment.

          (a)  This Agreement shall be effective as of the Effective Date.

          (b)  Employee's Employment shall terminate immediately upon the
     discharge of Employee by NOVA for "Cause."  For the purposes of this
     Agreement, the term "Cause," when used with respect to termination by NOVA
     of Employee's Employment hereunder, shall mean termination as a result of:
     (i) Employee's violation of the covenants set forth in Section 10 or 11;
     (ii) Employee's willful, intentional, or grossly negligent failure to
     perform his duties under this Agreement diligently and in accordance with
     the directions of NOVA; (iii) Employee's willful, intentional, or grossly
     negligent failure to comply with the decisions or policies of NOVA;  or
     (iv) final conviction of Employee of a felony; provided, however, that in
                                                    --------  -------
     the event NOVA desires to terminate Employee's Employment pursuant to
     subsections (i), (ii), or (iii) of this Section 6(b),

                                       4
<PAGE>

     NOVA shall first give Employee written notice of such intent, detailed and
     specific description of the reasons and basis therefor, and thirty (30)
     days to remedy or cure such perceived breaches or deficiencies (the "Cure
     Period"); provided, however, that with respect only to breaches that it is
               --------  -------
     not possible to cure within such thirty (30) day period, so long as
     Employee is diligently using his best efforts to cure such breaches or
     deficiencies within such period and thereafter, the Cure Period shall be
     automatically extended for an additional period of time (not to exceed
     sixty (60) days) to enable Employee to cure such breaches or deficiencies,
     provided, further, that Employee continues to diligently use his best
     --------  -------
     efforts to cure such breaches or deficiencies. If Employee does not cure
     the perceived breaches or deficiencies within the Cure Period, NOVA may
     discharge Employee immediately upon written notice to Employee. If NOVA
     desires to terminate Employee's Employment pursuant to subsection (iv) of
     this Section 6(b), NOVA shall first give Employee three (3) days prior
     written notice of such intent. Notwithstanding anything to the contrary
     contained herein, NOVA shall not be entitled to discharge Employee for
     "Cause" pursuant to this provision because of Employee's failure to perform
     his duties or to comply with the decisions or policies of NOVA if
     performance of such duties or compliance with such decisions or policies of
     NOVA would be illegal or inconsistent with the rules and regulations of any
     regulatory agency governing the duties of a Chief Financial Officer or
     Principal Accounting Officer.

          (c)  Employee's Employment shall terminate immediately upon the death
     of Employee.

          (d)  Employee's Employment shall terminate immediately upon thirty
     (30) days prior written notice to Employee if Employee shall at any time be
     incapacitated by reason of physical or mental illness or otherwise become
     incapable of performing the duties under this Agreement for a continuous
     period of one hundred eighty (180) consecutive days; provided, however, to
                                                          --------  -------
     the extent NOVA could, with reasonable accommodation and without undue
     hardship, continue to employ Employee in some other capacity after such one
     hundred eighty (180) day period, NOVA shall, to the extent required by the
     Americans With Disabilities Act, offer to do so, and, if such offer is
     accepted by Employee, Employee shall be compensated accordingly.

          (e)  Employee may terminate this Agreement, upon thirty (30) days
     prior written notice to NOVA (the "Notice Period"), in the event (i) there
     is a material diminution in Employee's duties and responsibilities such
     that they no longer reflect duties and responsibilities customary for an
     executive officer of a publicly-traded company; provided, however, that
                                                     --------  -------
     NOVA's change to a privately-held company (for example, as a result of
     acquisition) and the corresponding change in Employee's duties and
     responsibilities shall not, by itself, be sufficient to qualify as a
     "Responsibilities Breach"; (ii) Employee is required to relocate to an
     office that is more than thirty-five (35) miles from Employee's current
     office located at One Concourse Parkway, Suite 300, Atlanta, Georgia
     30328; (iii) there is a reduction in Employee's Base Salary payable under
     Section 2, an adverse change in the terms of the Incentive Compensation
     Plan, or a material reduction in benefits provided to Employee under
     Section 3 (whether occurring at once or over a period of time); or (iv)
     NOVA materially breaches this Agreement, (each of (i), (ii), (iii) and (iv)
     being referred to as a "Responsibilities Breach"), and NOVA fails to cure
     said Responsibilities Breach within the Notice Period; provided, however,
                                                            --------  -------
     that with respect only to

                                       5
<PAGE>

     breaches that it is not possible to cure within the Notice Period, so long
     as NOVA is diligently using its best efforts to cure such breaches within
     such Notice Period, the Notice Period shall be automatically extended for
     an additional period of time (not to exceed sixty (60) days) to enable NOVA
     to cure such breaches, provided, further, that NOVA continues to diligently
                            --------  -------
     use its best efforts to cure such breaches. Notwithstanding anything to the
     contrary in this Section 6(e), the Notice Period for any breach arising
     from the failure to pay compensation shall be five (5) days.

          (f)  Employee may terminate this Agreement at any time, without cause,
     upon thirty (30) days prior written notice to NOVA.

          (g)  NOVA may terminate this Agreement at any time, without cause,
     upon written notice to Employee.

          (h)  This Agreement shall automatically renew for successive one (1)
     year terms (each a "Renewal Term") unless either party hereto gives the
     other party hereto written notice of its or his intent not to renew this
     Agreement no later than one hundred eighty (180) days prior to the date the
     Initial Term, or the then-current Renewal Term, is scheduled to expire.
     Employee's Employment shall terminate upon termination or expiration of
     this Agreement.

     7.   Termination Payments.

          (a)  Upon termination of Employee's Employment, for whatever reason
     (other than termination for "Cause" pursuant to Section 6(b), termination
      ----- ----
     by Employee pursuant to Section 6(f), expiration of this Agreement
     following notice of non-renewal by Employee pursuant to Section 6(h), or
     termination because Employee otherwise "quits" or voluntarily terminates
     his employment other than pursuant to Section 6(e) (each, a "Termination
     Exclusion")) (the effective date of such termination or expiration being
     referred to as the "Termination Date"), in addition to any amounts payable
     to Employee hereunder (including but not limited to accrued but unpaid Base
     Salary), and any other benefits required to be provided to Employee and his
     dependents under contract and applicable law:

               (i)  NOVA shall pay Employee in cash an amount equal to his
          "Annual Base Compensation" (as defined in Section 7(f)) multiplied by
          two (2) (the "Severance Payment").  The Severance Payment shall be
          paid in twenty-four (24) equal monthly installments, the first of
          which shall be made on the first day of the calendar month following
          the calendar month in which the Termination Date occurs; provided,
          however, that:

                    (A)  if Employee's Employment is terminated (other than by
               reason of a Termination Exclusion) within two (2) years after a
               Change in Control of NOVA, NOVA shall pay Employee the Severance
               Payment in one lump sum within thirty (30) days of the
               Termination Date.

                    (B)  if, within the two-year period immediately following a
               Change in Control of NOVA, Employee's Employment is terminated by
               Employee pursuant to Section 6(f), because Employee "quits" or
               voluntarily terminates his

                                       6
<PAGE>

               employment or this Agreement expires following notice of non-
               renewal by Employee pursuant to Section 6(h), such a termination
               shall not be deemed to be a Termination Exclusion for purposes of
               this Section 7. Accordingly, NOVA shall pay Employee an amount
               equal to his Annual Base Compensation multiplied by two (2), and
               NOVA shall pay Employee this Severance Payment in one lump sum
               within thirty (30) days of the Termination Date; provided,
               however, in such a case, (i) Employee will not be paid any
               Supplemental Payment and (ii) Employee will not be entitled to
               his Bonus Compensation if such a terminating event occurs prior
               to the date when any accrued Bonus Compensation would be paid to
               Employee (even if he was employed for the entire calendar year
               upon which such Bonus Compensation would be calculated).

                     (C)  in the event Employee is terminated for Cause pursuant
               to the terms of Section 6(b), such event shall be governed by
               Section 7(b) hereof even if such Termination Date is within two
               (2) years after a Change in Control of NOVA.

               (ii)  NOVA shall pay Employee an amount (the "Supplemental
          Payment") equal to (x) the amount of Bonus Compensation payable to
          Employee for the calendar year immediately preceding the year in which
          the Termination Date occurs (the "Prior Bonus Amount") multiplied by
          (y) a fraction, the numerator of which is the number of days beginning
          on January 1/st/ of the calendar year in which the Termination Date
          occurs and ending on the Termination Date, and the denominator of
          which is 365.  The Supplemental Payment shall be paid to Employee
          concurrently with the payment of the Prior Bonus Amount; provided,
          however, that if the Prior Bonus Amount has already been paid to
          Employee, the Supplemental Payment shall be paid within 30 days of the
          Termination Date.  In the event the Termination Date occurs in the
          first calendar year of Employee's employment, then the Supplemental
          Payment shall equal the pro rata percentage (determined using the
          fraction above) of the Bonus Compensation Employee would have received
          for the calendar year in which the Termination Date occurred had
          Employee remained employed for the entire calendar year in which the
          Termination Date occurred, and the Supplemental Payment shall be paid
          to Employee concurrently with NOVA's payment of Bonus Compensation
          generally for such calendar year.

               (iii) Notwithstanding any provision to the contrary in the NOVA
          Corporation Deferred Compensation Plan (the "Deferred Compensation
          Plan"), the Deferred Compensation Plan Administrative Committee will
          exercise its sole option and sole discretion pursuant to Sections 7.02
          and 9.02 of the Deferred Compensation Plan, and will determine that
          Employee shall become fully vested immediately in all of his Deferred
          Compensation Plan accounts as of the Termination Date.

               (iv)  Notwithstanding any provision to the contrary in any other
          agreement or document (including but not limited to NOVA's applicable
          plan documents), all stock options, restricted stock and other similar
          rights that, as of the Termination Date, have been granted to Employee
          shall become vested and exercisable immediately upon notice

                                       7
<PAGE>

          of such termination. As provided under the applicable plan or
          agreement, Employee shall have the right to exercise any or all of
          such rights. Further, in the event Employee's Employment is terminated
          for whatever reason (other than termination for "Cause" pursuant to
          Section 6(b)) within two (2) years after a Change in Control of NOVA,
          Employee shall have the continuing right to exercise the "Qualified
          Options" (as defined in Section 7(f)(iv)), at any time prior to the
          date which is one (1) year after the Termination Date (without regard
          to any provision thereof requiring earlier expiration upon termination
          of employment).

               (v)   Until the earlier to occur of (x) the expiration of the
          Severance Period or (y) Employee becomes an employee of another
          company providing Employee and his dependents with medical, life and
          disability insurance (the period from the Termination Date until such
          event being referred to herein as the "Continuation Period"), NOVA
          shall provide to Employee and his dependents the coverage for the
          benefits described in Sections 3(a), (b) and (c) on the same terms and
          conditions as it provides such coverage to its currently employed
          Executive Vice Presidents; provided, however, such coverage shall not
          be provided to the extent that such coverage is generally provided
          through an insurance contract with a licensed insurance company and
          such insurance company will not agree to insure for such coverage.

     During the two (2) year period following the Termination Date (the
     "Severance Period"), Employee shall comply with the non-disclosure
     obligations and covenants not to disclose confidential information, solicit
     or compete set forth in Sections 10, 11, and 12 below.  If Employee is
     found by a court of competent jurisdiction or an arbitrator to be in breach
     of Section 10, 11, or 12 as they are written, Employee shall have no
     further right to any unpaid installment of the Severance Payment.  In
     addition, Employee shall be obligated to repay to Employer all installments
     of the Severance Payment delivered to him by Employer from the time the
     Employee first breached Section 10, 11, and/or 12 through the date of the
     court or arbitrator's decision.

     Except as provided in Section 7(a)(i)(B), for purposes of this Section
     7(a), any accrued but unpaid Bonus Compensation shall be paid to Employee
     on the date that Bonus Compensation would have been payable under the
     Incentive Compensation Plan had termination of Employee's Employment not
     occurred.

          (b)  In the event Employee's Employment is terminated as a result of
     the Termination Exclusions identified in Section 7(a), Employee shall be
     paid his accrued but unpaid Base Salary through the Termination Date, and
     any other benefits required to be provided to Employee and his dependents
     under contract and applicable law.  Employee will not be entitled to his
     Bonus Compensation if Employee's Employment is terminated as a result of
     one of the Termination Exclusions prior to the date when any earned Bonus
     Compensation would be paid to Employee.  In such a case, Employee shall not
     be entitled to any portion of his Bonus Compensation upon such termination
     of employment even if he was employed for the entire calendar year upon
     which such Bonus Compensation would be calculated.

          (c)  In the event Employee's Employment is terminated as a result of
     one of the Termination Exclusions identified in Section 7(a), NOVA, at its
     sole option and its sole discretion and at any time within thirty (30) days
     of the Termination Date, may cause Employee to be obligated to comply with
     the non-disclosure obligations and covenants not to solicit or compete set
     forth in Sections 10 and 11 below for a period of one (1) or two (2) years
     following the Termination Date, as set forth below:

               (i)   By giving notice to Employee at any time within thirty (30)
          days of the Termination Date of its intent to exercise the "One Year
          Option" herein described, NOVA may cause Employee to be obligated to
          comply with the non-disclosure obligations and covenants not to
          solicit or compete set forth in Sections 10 and 11 below for a period
          of one (1) year following the Termination Date; provided, however,
          that NOVA shall pay Employee an aggregate amount in cash equal to
          Employee's then Base Salary in effect immediately prior to the
          Termination Date multiplied by one (1) (the "One Year Payment").  The
          One Year Payment shall be paid by NOVA to Employee in twelve (12)
          equal monthly installments, the first of which shall be made on the
          first day of the calendar month following the calendar month in which
          the Termination Date occurs.  In the event NOVA exercises the One Year
          Option, the one (1) year period following the Termination Date shall
          be deemed the "Exclusion Period";

               (ii)  By giving notice to Employee any time within thirty (30)
          days of the Termination Date of its intent to exercise the "Two Year
          Option" herein described, NOVA may cause Employee to be obligated to
          comply with the non-disclosure obligations and covenants not to
          solicit or compete set forth in Sections 10 and 11 below for a period
          of two (2) years following the Termination Date; provided, however,
          that NOVA shall pay Employee an aggregate amount in cash equal to
          Employee's Base Salary in effect immediately prior to the Termination
          Date multiplied by two (2) (the "Two Year Payment").  The Two Year
          Payment shall be paid by NOVA to Employee in twenty-four (24) equal
          monthly installments, the first of which shall be made on the first
          day of the calendar month following the calendar month in which the
          Termination Date occurs.  In the event NOVA exercises the Two Year
          Option, the two (2) year period following the Termination Date shall
          be deemed the "Exclusion Period".

               (iii) During the Exclusion Period, if Employee is found by a
          court of competent jurisdiction or an arbitrator to be in breach of
          Section 10, 11, or 12 as they are written, Employee shall have no
          further right to any unpaid portion of the applicable Payment.  In
          addition, Employee shall be obligated to repay to Employer all
          portions of the applicable Payment delivered to him by Employer from
          the time Employee first breached Section 10, 11, and/or 12 through the
          date of the court's or arbitrator's decision.

          (d)  In the event of the death of Employee, all benefits and
     compensation hereunder shall, unless otherwise specified by Employee, be
     payable to, or exercisable by, Employee's estate.

          (f)  Gross-Up Payment.

               (i)  Anything in this Agreement to the contrary notwithstanding,
          in the event it shall be determined that any payment or distribution
          by or on behalf of NOVA to or for the benefit of Employee as a result
          of a "Change in Control" or as otherwise payable under Sections 3(h)
          or 7(a) (whether paid or payable or distributed or distributable
          pursuant to the terms of this Agreement or otherwise, but determined
          without regard to any additional payments required under this Section
          7(e) (a "Payment")) would be subject to the excise tax imposed by
          Section 4999 of the Internal Revenue Code of 1986, as amended (the
          "Code"), or any interest or penalties are incurred by Employee with
          respect to such excise tax (such excise tax, together with any such
          interest and penalties, are hereinafter collectively referred to as
          the "Excise Tax"), then Employee shall be entitled to receive an
          additional payment (a "Gross-Up Payment") in an amount such that,
          after payment by Employee of all taxes upon the Gross-Up Payment (such
          taxes including, without limitation, any income taxes and Excise Tax
          imposed upon the Gross-Up Payment, and any interest or penalties
          imposed with respect to such taxes), Employee retains an amount of the
          Gross-Up Payment equal to the Excise Tax imposed upon the Payment.

               (ii) Subject to the provisions of Section 7(e)(iii), all
          determinations required to be made under this Section 7, including
          whether and when a Gross-Up Payment is required and the amount of such
          Gross-Up Payment and the assumptions to be utilized in arriving at
          such determination, shall be made by a nationally recognized
          accounting firm or law firm selected by Employee and reasonably
          acceptable to NOVA (the "Tax Firm"); provided, however, that the Tax
                                               --------  -------
          Firm shall not determine that no Excise Tax is payable by Employee
          unless it delivers to Employee a written opinion (the "Accounting
          Opinion") that failure to pay the Excise Tax and to report the Excise
          Tax and the payments potentially subject thereto on or with Employee's
          applicable federal income tax return will not result in the imposition
          of an accuracy-related or other penalty on Employee.  All fees and
          expenses of the Tax Firm shall be borne solely by NOVA.  Within
          fifteen (15) business days of the receipt of notice from Employee that
          there has been a Payment, the Tax Firm shall make all determinations
          required under this Section 7, shall provide to NOVA and Employee a
          written report setting forth such determinations, together with
          detailed supporting calculations, and, if the Tax Firm determines that
          no Excise Tax is payable, shall deliver the Accounting Opinion to
          Employee.  Any Gross-Up Payment, as determined pursuant to this
          Section 7, shall be paid by NOVA to Employee within fifteen (15) days
          of the receipt of the Tax Firm's determination.  Subject to the
          remainder of this Section, any determination by the Tax Firm shall be
          binding upon NOVA and Employee; provided, however, that Employee shall
          only be bound to the extent that the determinations of the Tax Firm
          hereunder, including the determinations made in the Accounting
          Opinion, are reasonable and reasonably supported by applicable law.
          As a result of the uncertainty in the application of Section 4999 of
          the Code at the time of the initial determination by the Tax Firm
          hereunder, it is possible that Gross-Up Payments which will not have
          been made by NOVA should have been made ("Underpayment"), consistent
          with the calculations

                                       10
<PAGE>

          required to be made hereunder. In the event that it is ultimately
          determined in accordance with the procedures set forth in Section
          7(e)(iii) that Employee is required to make a payment of any Excise
          Tax, the Tax Firm shall reasonably determine the amount of the
          Underpayment that has occurred and any such Underpayment shall be
          promptly paid by NOVA to or for the benefit of Employee. In
          determining the reasonableness of Tax Firm's determinations hereunder,
          and the effect thereof, NOVA and Employee shall be provided a
          reasonable opportunity to review such determinations with Tax Firm and
          their respective tax counsel, if separate from the Tax Firm. Tax
          Firm's determinations hereunder, and the Accounting Opinion, shall not
          be deemed reasonable until Employee's reasonable objections and
          comments thereto have been satisfactorily accommodated by Tax Firm.

               (iii) Employee shall notify NOVA in writing of any claims by the
          Internal Revenue Service that, if successful, would require the
          payment by NOVA of the Gross-Up Payment. Such notification shall be
          given as soon as practicable, but no later than thirty (30) calendar
          days after Employee actually receives notice in writing of such claim,
          and shall apprise NOVA of the nature of such claim and the date on
          which such claim is requested to be paid; provided, however, that the
                                                    --------  -------
          failure of Employee to notify NOVA of such claim (or to provide any
          required information with respect thereto) shall not affect any rights
          granted to Employee under this Section except to the extent that NOVA
          is materially prejudiced in the defense of such claim as a direct
          result of such failure.  Employee shall not pay such claim prior to
          the expiration of the thirty (30) day period following the date on
          which he gives such notice to NOVA (or such shorter period ending on
          the date that any payment of taxes with respect to such claim is due).
          If NOVA notifies Employee in writing prior to the expiration of such
          period that it desires to contest such claim, Employee shall do all of
          the following:

                     (A) give NOVA any information reasonably requested by NOVA
                         relating to such claim;

                     (B) take such action in connection with contesting such
                         claim as NOVA shall reasonably request in writing from
                         time to time, including, without limitation, accepting
                         legal representation with respect to such claim by an
                         attorney selected by NOVA and reasonably acceptable to
                         Employee;

                     (C) cooperate with NOVA in good faith in order effectively
                         to contest such claim;

                     (D) if NOVA elects not to assume and control the defense of
                         such claim, permit NOVA to participate in any
                         proceedings relating to such claim; provided, however,
                         that NOVA shall bear and pay directly all costs and
                         expenses (including additional interest and penalties)
                         incurred in connection with such contest and shall
                         indemnify and hold Employee harmless, on an after-tax
                         basis, for any Excise Tax or income tax (including
                         interest and penalties with respect thereto) imposed as
                         a result

                         of such representation and payment of costs and
                         expenses. Without limiting the foregoing provisions of
                         this Section 7, NOVA shall have the right, at its sole
                         option, to assume the defense of and control all
                         proceedings in connection with such contest, in which
                         case it may pursue or forego any and all administrative
                         appeals, proceedings, hearings and conferences with the
                         taxing authority in respect of such claim and may
                         either direct Employee to pay the tax claimed and sue
                         for a refund or contest the claim in any permissible
                         manner, and Employee agrees to prosecute such contest
                         to a determination before any administrative tribunal,
                         in a court of initial jurisdiction and in one or more
                         appellate courts, as NOVA shall determine; provided,
                                                                    --------
                         however, that if NOVA directs Employee to pay such
                         -------
                         claim and sue for a refund, NOVA shall advance the
                         amount of such payment to Employee, on an interest-free
                         basis and shall indemnify and hold Employee harmless,
                         on an after-tax basis, from any Excise Tax or income
                         tax (including interest or penalties with respect
                         thereto) imposed with respect to such advance or with
                         respect to any imputed income with respect to such
                         advance; and further provided that any extension of the
                         statute of limitations relating to payment of taxes for
                         the taxable year of Employee with respect to which such
                         contested amount is claimed to be due is limited solely
                         to such contested amount. Furthermore, NOVA's right to
                         assume the defense of and control the contest shall be
                         limited to issues with respect to which a Gross-Up
                         Payment would be payable hereunder and Employee shall
                         be entitled to settle or contest, as the case may be,
                         any other issue raised by the Internal Revenue Service
                         or any other taxing authority.

                    (iv) If, after the receipt by Employee of an amount advanced
          by NOVA pursuant to this Section 7(e), Employee becomes entitled to
          receive any refund with respect to such claim, Employee shall (subject
          to NOVA's complying with the requirements of Section 7(e)(iii))
          promptly pay to NOVA the amount of such refund (together with any
          interest paid or credited thereon after taxes applicable thereto). If,
          after the receipt by Employee of an amount advanced by NOVA pursuant
          to Section 7(e)(iii), a determination is made that Employee is not
          entitled to a refund with respect to such claim and NOVA does not
          notify Employee in writing of its intent to contest such denial of
          refund prior to the expiration of thirty (30) days after such
          determination, then such advance shall, to the extent of such denial,
          be forgiven and shall not be required to be repaid and the amount of
          forgiven advance shall offset, to the extent thereof, the amount of
          Gross-Up Payment required to be paid.

          (f) For purposes of this Agreement, the following terms shall be
     defined as follows:

              (i)   "Change in Control" shall mean:

                    (A)  The acquisition (other than from NOVA) by any person,
                         entity or "group", within the meaning of Section
                         13(d)(3) or 14(d)(2)

                         of the Securities Exchange Act of 1934 (the "Exchange
                         Act") (excluding, for this purpose, any employee
                         benefit plan of NOVA or its subsidiaries which acquires
                         beneficial ownership of voting securities of NOVA) of
                         beneficial ownership (within the meaning of Rule 13d-3
                         promulgated under the Exchange Act) of 25% or more of
                         either the then outstanding shares of NOVA Stock or the
                         combined voting power of NOVA's then outstanding voting
                         securities entitled to vote generally in the election
                         of directors; or

                     (B) The consummation by NOVA of a reorganization, merger,
                         or consolidation, in each case, with respect to which
                         the shares of NOVA voting stock outstanding immediately
                         prior to such reorganization, merger or consolidation
                         do not constitute or become exchanged for or converted
                         into more than 50% of the combined voting power
                         entitled to vote generally in the election of directors
                         of the reorganized, merged or consolidated company's
                         then outstanding voting securities, or a liquidation or
                         dissolution of NOVA or of the sale of all or
                         substantially all of the assets of NOVA; and

                     (C) The failure for any reason of individuals who
                         constitute the Incumbent Board to continue to
                         constitute at least a majority of the board of
                         directors of (i) NOVA, if NOVA remains a publicly-
                         traded company, or (ii) the ultimate parent company, if
                         NOVA becomes a direct or indirect subsidiary of another
                         company.

                     (i.e., either (A) and (C) or (B) and (C) must occur in
                     order to constitute a Change in Control for purposes of
                     this definition).

                     Notwithstanding the foregoing definition, a leverage buyout
                     transaction whereby NOVA becomes a privately-held company

          shareholders, was approved by a vote of at least a majority of the

including, without limitation, all customer data, billing information, service
data, and other technical material of NOVA is and shall be NOVA's property.
Employee agrees to deliver without demand all such materials to NOVA within
three (3) days after the termination of Employee's Employment.  Employee further
agrees not to use such materials for any reason after said termination.

     9.   Arbitration.

          (a)  NOVA and Employee acknowledge and agree that (except as
     specifically set forth in Section 9(d)) any claim or controversy arising
     out of or relating to this Agreement shall be settled by binding
     arbitration in Atlanta, Georgia, in accordance with the National Rules of
     the American Arbitration Association for the Resolution of Employment
     Disputes in effect on the date of the event giving rise to the claim or
     controversy.  NOVA and Employee further acknowledge and agree that either
     party must request arbitration of any claim or controversy within one (1)
     year of the date of the event giving rise to the claim or controversy by
     giving written notice of the party's request for arbitration.  Failure to
     give notice of any claim or controversy within one (1) year of the event
     giving rise to the claim or controversy shall constitute waiver of the
     claim or controversy.

          (b)  All claims or controversies subject to arbitration pursuant to
     Section 9(a) above shall be submitted to arbitration within six (6) months
     from the date that a written notice of request for arbitration is
     effective.  All claims or controversies shall be resolved by a panel of
     three arbitrators who are licensed to practice law in the State of Georgia
     and who are experienced in the arbitration of labor and employment
     disputes.  These arbitrators shall be selected in accordance with the
     National Rules of the American Arbitration Association for the Resolution
     of Employment Disputes in effect at the time the claim or controversy
     arises.  Either party may request that the arbitration proceeding be
     stenographically recorded by a Certified Shorthand

                                       14
<PAGE>

     Reporter. The arbitrators shall issue a written decision with respect to
     all claims or controversies within thirty (30) days from the date the
     claims or controversies are submitted to arbitration. The parties shall be
     entitled to be represented by legal counsel at any arbitration proceedings.

          (c)  NOVA and Employee acknowledge and agree that the arbitration
     provisions in this Agreement may be specifically enforced by either party,
     and that submission to arbitration proceedings may be compelled by any
     court of competent jurisdiction.  NOVA and Employee further acknowledge and
     agree that the decision of the arbitrators may be specifically enforced by
     either party in any court of competent jurisdiction.

          (d)  Notwithstanding the arbitration provisions set forth herein,
     Employee and NOVA acknowledge and agree that nothing in this Agreement
     shall be construed to require the arbitration of any claim or controversy
     arising under Sections 10, 11, and 12 of this Agreement nor shall such
     provisions prevent NOVA from seeking equitable relief from a court of
     competent jurisdiction for violations of Sections 10, 11, and 12 of this
     Agreement.  These provisions shall be enforceable by any court of competent
     jurisdiction and shall not be subject to arbitration except by mutual
     written consent of the parties signed after the dispute arises, any such
     consent, and the terms and conditions thereof, then becoming binding on the
     parties.  Employee and NOVA further acknowledge and agree that nothing in
     this Agreement shall be construed to require arbitration of any claim for
     workers' compensation or unemployment compensation.

10.  Nondisclosure.

          (a)  NOVA Confidential Information.  Employee acknowledges and agrees
               -----------------------------
     that because of his Employment, he will have access to proprietary
     information of NOVA concerning or relative to the Business (collectively,
     "NOVA Confidential Information") which includes, without limitation,
     technical material of NOVA, sales and marketing information, customer
     account records, billing information, training and operations information,
     materials and memoranda, personnel records, pricing and financial
     information relating to the business, accounts, customers, prospective
     customers, employees and affairs of NOVA, and any information marked
     "Confidential" by NOVA.  Employee acknowledges and agrees that NOVA
     Confidential Information is and shall be NOVA's property.  Employee agrees
     that during the term of his Employment, Employee shall keep NOVA
     Confidential Information confidential, and Employee shall not use NOVA
     Confidential Information for any reason other than on behalf of NOVA
     pursuant to, and in strict compliance with, the terms of this Agreement.
     Employee further agrees that during the Severance Period or the Exclusion
     Period, as applicable, Employee shall continue to keep NOVA Confidential
     Information confidential, and Employee shall not use NOVA Confidential
     Information for any reason or in any manner.

          (b)  Notwithstanding the foregoing, Employee shall not be subject to
     the restrictions set forth in subsection (a) of this Section 10 with
     respect to information which:

               (i)  becomes generally available to the public other than as a
          result of disclosure by Employee or the breach of Employee's
          obligations under this Agreement;

                                       15
<PAGE>

               (ii)  becomes available to Employee from a source which is
          unrelated to his Employment or the exercise of his duties under this
          Agreement, provided that such source lawfully obtained such
          information and is not bound by a confidentiality agreement with NOVA;
          or

               (iii) is required by law to be disclosed.

          (c)  Trade Secrets.  Employee acknowledges and agrees that because of
               -------------
     his Employment, he will have access to "trade secrets" (as defined in the
     Uniform Trade Secrets Act, O.C.G.A. (S) 10-1-760, et seq. (the "Uniform
                                                       -- ---
     Trade Secrets Act") of NOVA ("Trade Secrets").  Nothing in this Agreement
     is intended to alter the applicable law and remedies with respect to
     information meeting the definition of "trade secrets" under the Uniform
     Trade Secrets Act, which law and remedies shall be in addition to the
     obligations and rights of the parties hereunder.

     11.  Covenant Not to Compete.  Employee acknowledges and agrees that,
because of his Employment, he will have access to confidential or proprietary
information concerning merchants, associate banks and ISOs of NOVA and shall
have established relationships with such merchants, associate banks and ISOs as
well as with the vendors, consultants, and suppliers used to service such
merchants, associate banks and ISOs.  Employee agrees that during the term of he
Employment and continuing through the Severance Period or the Exclusion Period
as applicable, Employee shall not, either individually, in partnership, jointly,
or in conjunction with, or on behalf of, any person, firm, partnership,
corporation, or unincorporated association or entity of any kind:

          (a)  perform services within the United States (the "Territory") in a
     financial, supervisory, or managerial capacity or as an advisor, consultant
     or independent contractor for any person, firm, partnership, corporation,
     or unincorporated association of any kind which is providing credit card
     and/or debit card transaction processing services within the Territory;

          (b)  obtain any ownership or financial interest in (except as a
     stockholder holding less than five percent (5%) interest in a corporation
     which is traded on a national exchange or over the counter) any firm,
     partnership, corporation or unincorporated association of any kind which is
     providing credit card and/or debt card transaction processing services.

     12.  Covenant Not to Solicit. Employee further agrees that during the term
of his Employment and continuing through the Severance Period or the Exclusion
Period as applicable, Employee shall not:

          (a)  solicit or contact, for the purpose of providing products or
     services the same as or substantially similar to those provided by NOVA in
     connection with the Business, any person or entity that during the term of
     Employee's Employment was a merchant, associate bank, ISO or customer
     (including any actively-sought prospective merchant, associate bank, ISO or
     customer) of NOVA and with whom Employee had material contact or about whom
     Employee learned material information during the last twelve (12) months of
     his Employment;

          (b)  persuade or attempt to persuade any merchant, associate bank,
     ISO, customer, or supplier of NOVA to terminate or modify such merchant's,
     associate bank's, ISO's, customer's,

                                       16
<PAGE>

     or supplier's relationship with NOVA if Employee had material contact with
     or learned material information about such merchant, associate bank, ISO,
     customer or supplier during the last twelve (12) months of his Employment;
     or

          (c)  persuade or attempt to persuade any person who (i) was employed
     by NOVA or under agreement to provide services as an independent contractor
     to NOVA as of the date of the termination of Employee's Employment and (ii)
     is in a sales or management position with NOVA at the time of such contact,
     to terminate or modify his employment or other contractual relationship,
     whether or not pursuant to a written agreement, with NOVA, as the case may
     be.

     13.  New Developments.  Any discovery, invention, process or improvement
made or discovered by Employee during the term of his Employment in connection
with or in any way affecting or relating to the Business (as then carried on or
under active consideration) shall forthwith be disclosed to NOVA and shall
belong to and be the absolute property of NOVA; provided, however, that this
provision does not apply to an invention for which no equipment, supplies,
facility, trade secret information of NOVA was used and which was developed
entirely on Employee's own time, unless (a) the invention relates (i) directly
to the Business or (ii) to NOVA's actual or demonstrably anticipated research or
development; or (b) the invention results from any work performed by Employee
for NOVA.

     14.  Remedy for Breach.  Employee acknowledges and agrees that his breach
of any of the covenants contained in Sections 8, 10, 11, 12 and 13 of this
Agreement would cause irreparable injury to NOVA and that remedies at law of
NOVA for any actual or threatened breach by Employee of such covenants would be
inadequate and that NOVA shall be entitled to specific performance of the
covenants in such sections or injunctive relief against activities in violation
of such sections, or both, by temporary or permanent injunction or other
appropriate judicial remedy, writ or order, without the necessity of proving
actual damages.  This provision with respect to injunctive relief shall not
diminish the right of NOVA to claim and recover damages against Employee for any
breach of this Agreement in addition to injunctive relief.  Employee
acknowledges and agrees that the covenants contained in Sections 8, 10, 11, 12
and 13 of this Agreement shall be construed as agreements independent of any
other provision of this or any other contract between the parties hereto, and
that the existence of any claim or cause of action by Employee against NOVA,
whether predicated upon this or any other contract, shall not constitute a
defense to the enforcement by NOVA of said covenants.

     15.  Reasonableness.  Employee has carefully considered the nature and
extent of the restrictions upon him and the rights and remedies conferred on
NOVA under this Agreement, and Employee hereby acknowledges and agrees that:

          (a)  the restrictions and covenants contained herein, and the rights
     and remedies conferred upon NOVA, are necessary to protect the goodwill and
     other value of the Business;

          (b)  the restrictions placed upon Employee hereunder are narrowly
     drawn, are fair and reasonable in time and territory, will not prevent him
     from earning a livelihood, and place no greater restraint upon Employee
     than is reasonably necessary to secure the Business and goodwill of NOVA;

                                       17
<PAGE>

          (c)  NOVA is relying upon the restrictions and covenants contained
     herein in continuing to make available to Employee information concerning
     the Business; and

          (d)  Employee's Employment places him in a position of confidence and
     trust with NOVA and its employees, merchants, associate banks, ISOs,
     customers, vendors and suppliers.

          (e)  The restrictions placed on Employee pursuant to Sections 11 and
     12 above are reasonable as to time and geographic area, in consideration of
     the unique character of NOVA's business and Employee's high position in
     NOVA's corporate structure. Sections 10, 11, and 12 also are definite as to
     time. Employee understands that under certain circumstances the Agreement
     allows NOVA to elect one or two years of protection under these Sections.
     Employee agrees that he is receiving good and valuable consideration for
     the providing NOVA with this election.

     16.  Invalidity of Any Provision.  It is the intention of the parties
hereto that the provisions of this Agreement shall be enforced to the fullest
extent permissible under the laws and public policies of each state and
jurisdiction in which such enforcement is sought, but that the unenforceability
(or the modification to conform with such laws or public policies) of any
provision hereof shall not render unenforceable or impair the remainder of this
Agreement which shall be deemed amended to delete or modify, as necessary, the
invalid or unenforceable provisions.  The parties further agree to alter the
balance of this Agreement in order to render the same valid and enforceable.
The terms of the non-competition provisions of this Agreement shall be deemed
modified to the extent necessary to be enforceable and, specifically, without
limiting the foregoing, if the term of the non-competition is too long to be
enforceable, it shall be modified to encompass the longest term which is
enforceable and, if the scope of the geographic area of non-competition is too
great to be enforceable, it shall be modified to encompass the greatest area
that is enforceable.  The parties further agree to submit any issues regarding
such modification to a court of competent jurisdiction.  If said court declines
to so amend or modify this Agreement, the parties either will agree to modify
the term in question to make it enforceable or will submit the Agreement to
binding arbitration in accordance with the commercial arbitration rules then in
effect of the American Arbitration Association for the purpose of modifying the
covenant in question so that it is enforceable.  By this Agreement, the parties
expressly grant the arbitrator to authority to make a binding determination as
to what restriction will, under these circumstances, be enforceable.  Any such
arbitration hearing will be held in Atlanta, Georgia, and this Agreement shall
be construed and enforced in accordance with the laws of the State of Georgia,
including this arbitration provision.

     17.  Full Settlement and Legal Expenses.  NOVA's obligation to make the
payments provided for in this Agreement and otherwise to perform its obligations
hereunder shall not be affected by any set-off, counter-claim, recoupment,
defense or other claim, right or action which NOVA may have against the Employee
or others.  In no event shall the Employee be obligated to seek other employment
or take any other action by way of mitigation of the amounts payable to the
Employee under any of the provisions of this Agreement.  NOVA agrees to pay, to
the full extent permitted by law, all legal fees and expenses which the Employee
may reasonably incur as a result of any legitimate, non-frivolous contest
(regardless of the outcome thereof) by NOVA or others of the validity or
enforceability of, or liability under, any provision of this Agreement or any
guarantee of performance thereof (including as a result of any legitimate, non-
frivolous contest by the Employee about the amount of any payment pursuant to

                                       18
<PAGE>

Section 7 of this Agreement), plus in each case interest at the applicable
federal rate provided for in Section 7872(f)(2) of the Code. NOVA will not be
bound to pay any legal fees or expenses arising out of baseless, meritless or
frivolous contests brought hereunder by Employee or others. A contest will be
deemed baseless, meritless and/or frivolous if a court or other arbiter assesses
penalties or sanctions for bringing said contest, or a court or other arbiter
dismisses said contest for failure to state a colorable claim.

     18.  Applicable Law.  This Agreement shall be construed and enforced in
accordance with the laws of the State of Georgia.

     19.  Waiver of Breach.  The waiver by NOVA of a breach of any provision of
this Agreement by Employee shall not operate or be construed as a waiver of any
subsequent breach by Employee.

     20.  Successors and Assigns.  This Agreement shall inure to the benefit of
NOVA, its subsidiaries and affiliates, and their respective successors and
assigns.  This Agreement is not assignable by Employee but shall be freely
assignable by NOVA.

     21.  Notices.  All notices, demands and other communications hereunder
shall be in writing and shall be delivered in person or deposited in the United
States mail, certified or registered, with return receipt requested, as follows:

writing signed by the party against whom enforcement of any waiver, change,
modification, extension, or discharge is sought.

     23.  Indemnification.  At all times during and after Employee's Employment

law and shall at all times maintain appropriate provisions in its Articles of
Incorporation and Bylaws which mandate that NOVA provide such indemnification.

     24.  Survival.  The provisions of Sections 7, 8, 9, 10, 11, 12, 13, 14, 15,

     25.  Withholding.  All payments required to be made by NOVA under this
Agreement will be subject to the withholding of such amounts, if any, relating
to federal, state and local taxes as may be required by law.  Nothing in this
Section shall be construed to reduce Employee's right to payments described in
Section 7(e).

                                   ---------

                     Annual Incentive Compensation Schedule

*    Payment of annual incentive compensation (the "Bonus Payment") to be based
     upon relative achievement of Targeted Net Income (as defined).

*    Net Income is Net Income determined in accordance with GAAP as determined
     from the annual audited Financial Statements, as adjusted to exclude non-
     operating gains and losses.

*    Targeted Net Income will be established annually by the Board of Directors.

*    The Bonus Payment will be calculated by following the steps outlined below:

     (1)  Determining the percentage equivalent to a fraction, the numerator of
          which is Net Income and the denominator of which is Targeted Net
          Income (such percentage being referred to as the "Actual/Targeted
          Ratio").

     (2)  Values will be calculated based on (A) through (E):

          (A)  For each full percentage point (up to 84%) by which the
                   ----
               Actual/Targeted Ratio equals or exceeds 80%, a value of 1% will
               be awarded.

          (B)  For each full percentage point (up to 89%) by which the
                   ----
               Actual/Targeted Ratio exceeds 84%, a value of 2% will be awarded.

          (C)  For each full percentage point (up to 94%) by which the
                   ----
               Actual/Targeted Ratio exceeds 89%, a value of 3% will be awarded.

          (D)  For each full percentage point (up to 99%) by which the
                   ----
               Actual/Targeted Ratio exceeds 94%, a value of 4% will be awarded.

          (E)  For each full percentage point (up to 150%) by which the
                   ----
               Actual/Targeted Ratio exceeds 100%, a value of 1% will be
               awarded. (note:  for this purpose, no value will be awarded for
                         ----
               equaling 100%).

     (3)  The sum of the values calculated in (A) through (E) (the "Bonus
          Percentage") shall be multiplied by Employee's then current Base
          Salary to yield the Bonus Payment.

     Examples:
     ---------

     .    If the Actual/Targeted Ratio is 92%, the Bonus Percentage would be
          29%. This is calculated by adding:

                     5%  (1% for 80-84% of Actual/Targeted Ratio)
               +    15%  (2% for 85-89% of Actual/Targeted Ratio)
               +     9%  (3% for 90-92% of Actual/Targeted Ratio)
                    ---------------------------------------------
                    29%

          Employee's Bonus Payment would be equal to Employee's then-current
          Base Salary multiplied by 29%.

     .    If the Actual/Targeted Ratio is 112%, the Bonus Percentage would be
          62%. This is calculated by adding:

                     5%  (1% for 80-84% of Actual/Targeted Ratio)
               +    10%  (2% for 85-89% of Actual/Targeted Ratio)
               +    15%  (3% for 90-94% of Actual/Targeted Ratio)
               +    20%  (4% for 95-99% of Actual/Targeted Ratio)
               +     0%  (0% for 100% of Actual/Targeted Ratio)
               +    12%  (1% for 101-112% of Actual/Targeted Ratio)
                    -----------------------------------------------
                    62%

          Employee's Bonus Payment would be equal to Employee's then-current
          Base Salary multiplied by 62%.

*    The foregoing notwithstanding, in order for any bonus to be payable with
     respect to any calendar year, the "Revenue" (as defined below) for such
     calendar year must equal or exceed 105% of the Revenue for the immediately
     preceding calendar year.  "Revenue" means revenue of NOVA determined in
     accordance with GAAP as determined from the annual audited Financial
     Statements, as adjusted to exclude non-operating items.

*    Notwithstanding anything to the contrary in this Agreement, in order to
     receive Bonus Compensation for any calendar year, Employee must be employed
     by NOVA on the day that the Bonus Compensation is actually paid or on April
     15 of the following calendar year, whichever date occurs sooner.

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

     WHEREAS, NOVA, through its direct and indirect subsidiaries, is in the
business of providing credit card and debit card transaction processing services
and settlement services (including the related products and services of
automated teller machines and check guarantee services) to merchants, financial
institutions, independent sales organizations ("ISOs"), and other similar
customers (collectively, the "Business") throughout the United States;

     WHEREAS, Employee currently serves as Executive Vice President, General
Counsel and Secretary of NOVA pursuant to an Employment Agreement between
Employee and NOVA effective February 15, 1999 (the "Prior Agreement");

     WHEREAS, NOVA and Employee desire to terminate the Prior Agreement, which
termination shall be contemporaneous with the effectiveness of this Agreement;

     WHEREAS, NOVA, or its assigns, will continue to engage in the Business
throughout the United States (the "Territory");

     WHEREAS, NOVA desires that Employee work for NOVA, and Employee desires to
continue said employment, all as contemplated herein;

     NOW, THEREFORE, for and in consideration of her continued employment by
NOVA pursuant to this Agreement, the NOVA Confidential Information and Trade
Secrets (as hereafter defined) furnished to Employee by NOVA in order that she
may continue to perform her duties under this Agreement, the mutual covenants
and agreements herein contained, and other valuable consideration, the receipt
and sufficiency of which are hereby acknowledged, the parties hereto agree as
follows:

     1.   Employment of Employee.  NOVA hereby employs Employee for a period
beginning as of the Effective Date and ending two (2) years thereafter (the
"Initial Term"), unless Employee's employment by NOVA is sooner terminated or
automatically renewed pursuant to the terms of this Agreement (Employee's
employment by NOVA pursuant to the terms of this Agreement shall hereinafter be
referred to as "Employment").

          (a)  Employee agrees to such Employment on the terms and conditions
herein set forth and agrees to devote her reasonable best efforts to her duties
under this Agreement and to perform such duties diligently and efficiently and
in accordance with the directions of NOVA's Chief Executive Officer.

          (b)  During the term of Employee's Employment, Employee shall serve as
Executive Vice President, General Counsel and Secretary of NOVA.  Employee shall
be responsible primarily for such duties as are assigned to her, from time to
time, by NOVA's Chief Executive Officer, which in any event shall be such duties
as are customary for an officer in those positions.

          (c)  Employee shall devote substantially all of her business time,
attention, and energies to NOVA's Business, shall act at all times in the best
interests of NOVA, and shall not during the
<PAGE>

term of her Employment be engaged in any other business activity, whether or not
such business is pursued for gain, profit, or other pecuniary advantage, or
permit such personal interests as she may have to interfere with the performance
of her duties hereunder. Notwithstanding the foregoing, Employee may participate
in industry, civic and charitable activities so long as such activities do not

     2.   Compensation.  During the term of Employee's Employment and in
accordance with the terms hereof, NOVA shall pay or otherwise provide to
Employee the following compensation:

          (a)  Employee's annual salary during the term of her Employment shall
be Two Hundred Fifty Thousand and No/100 Dollars ($250,000) ("Base Salary"),
with such increases (each, a "Merit Increase") as may from time to time be
deemed appropriate by NOVA's Chief Executive Officer; provided, however, that so
long as this Agreement remains in effect, Employee's Base Salary shall be
reviewed annually by NOVA's Chief Executive Officer in each fiscal year, within
a reasonable time following the availability of NOVA's financial statements for
the preceding fiscal year. The Base Salary shall be paid by NOVA in accordance
with NOVA's regular payroll practice. As used herein, the term "Base Salary"
shall be deemed to include any Merit Increases granted to Employee.

          (b)  In addition to the Base Salary, Employee shall be eligible to
receive annual bonus compensation ("Bonus Compensation") in the amount, and on
the terms and conditions described in the Annual Incentive Compensation Schedule

payable to Employee under the Incentive Compensation Plan in shares of NOVA
common stock, par value $.01 per share ("NOVA Stock"), valued on the basis of
the closing price of NOVA Stock on the New York Stock Exchange on the date of
Employee's request (or if such date is not a trading day, on the immediately
preceding trading day); provided, however, that NOVA shall not be obligated to
comply with Employee's request if (i) NOVA does not have shares of NOVA Stock
available for issuance or (ii) the issuance of NOVA Stock to Employee would be
impracticable or impede, in any respect, NOVA's ongoing business operations.

          (c)  NOVA may withhold from any benefits payable under this Agreement
all federal, state, city or other taxes as shall be required pursuant to any law
or governmental regulation or ruling.

               -----------------
to participate in such medical, dental, vision, prescription drug, wellness, or
other health care or medical coverage plans as may be established, offered or

executive officers, pursuant to the terms set forth in such plans.

          (b)  Life Insurance. Employee shall be entitled to participate in any

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

Directors or the Compensation Committee.

          (f)  Other Benefits. In addition to and not in any way in limitation
               --------------

purchase plans, and fringe benefits) on the same basis as such are afforded to
other executive officers of NOVA during the term of this Agreement.

          (g)  Terms and Provisions of Plans. NOVA agrees that it shall not take
               -----------------------------
action (during the term of this Agreement or the "Continuation Period," as
defined in Section 7(a)) to modify the terms and provisions of any such plan or
arrangement so as to exclude only Employee and/or her dependents, either by
excluding Employee and/or her dependents explicitly by name or by modifying
provisions generally applicable to all employees and dependents so that only
Employee and/or her dependents would be affected.

          (h)  Vesting of Rights. Upon the occurrence of a "Change in Control"
               -----------------
(as defined in Section 7(f)) during the term of this Agreement, and regardless
of whether Employee terminates this Agreement following such occurrence, and
notwithstanding any provision to the contrary in any other agreement or document
(including NOVA's applicable plan documents), all stock options, restricted
stock, and other similar rights that have been granted to Employee and that are
not vested on the date of occurrence of such an event, as well as any Deferred
Compensation Plan balance that is not vested on the date of occurrence of such
an event, shall become vested and exercisable immediately (collectively, the

businesslike and professional manner as appropriate for a person in her position
and shall represent NOVA in all respects with good business and ethical
practices. In addition, Employee shall be subject to and abide by the policies

from time to time.

     5.   Reimbursement for Business Expenses.  Employee shall be reimbursed, on
no less frequently than a monthly basis, for all out-of-pocket business expenses
incurred by her in the performance of her duties hereunder, provided that
Employee shall first document and substantiate said business expenses in the
manner generally required by NOVA under its policies and procedures.

     6.   Term and Termination of Employment.

          (a)  This Agreement shall be effective as of the Effective Date.

          (b)  Employee's Employment shall terminate immediately upon the
discharge of Employee by NOVA for "Cause." For the purposes of this Agreement,
the term "Cause," when used with respect to termination by NOVA of Employee's
Employment hereunder, shall mean termination as a result of: (i) Employee's
violation of the covenants set forth in Section 10 or 11; (ii) Employee's
willful, intentional, or grossly negligent failure to perform her duties under
this Agreement diligently and in

                                       3
<PAGE>

accordance with the directions of NOVA; (iii) Employee's willful, intentional,
or grossly negligent failure to comply with the decisions or policies of NOVA;
or (iv) final conviction of Employee of a felony; provided, however, that in the
                                                  --------  -------
event NOVA desires to terminate Employee's Employment pursuant to subsections
(i), (ii), or (iii) of this Section 6(b), NOVA shall first give Employee written
notice of such intent, detailed and specific description of the reasons and
basis therefor, and thirty (30) days to remedy or cure such perceived breaches
or deficiencies (the "Cure Period"); provided, however, that with respect only
                                     --------  -------
to breaches that it is not possible to cure within such thirty (30) day period,
so long as Employee is diligently using her best efforts to cure such breaches
or deficiencies within such period and thereafter, the Cure Period shall be
automatically extended for an additional period of time (not to exceed sixty
(60) days) to enable Employee to cure such breaches or deficiencies, provided,
                                                                     --------
further, that Employee continues to diligently use her best efforts to cure such
-------
breaches or deficiencies. If Employee does not cure the perceived breaches or
deficiencies within the Cure Period, NOVA may discharge Employee immediately
upon written notice to Employee. If NOVA desires to terminate Employee's
Employment pursuant to subsection (iv) of this Section 6(b), NOVA shall first
give Employee three (3) days prior written notice of such intent.

          (c)  Employee's Employment shall terminate immediately upon the death
of Employee.

          (d)  Employee's Employment shall terminate immediately upon thirty
(30) days prior written notice to Employee if Employee shall at any time be
incapacitated by reason of physical or mental illness or otherwise become
incapable of performing the duties under this Agreement for a continuous period
of one hundred eighty (180) consecutive days; provided, however, to the extent
                                              --------  -------
NOVA could, with reasonable accommodation and without undue hardship, continue
to employ Employee in some other capacity after such one hundred eighty (180)
day period, NOVA shall, to the extent required by the Americans With
Disabilities Act, offer to do so, and, if such offer is accepted by Employee,
Employee shall be compensated accordingly.

          (e)  Employee may terminate this Agreement, upon thirty (30) days
prior written notice to NOVA (the "Notice Period"), in the event (i) there is a
material diminution in Employee's duties and responsibilities such that they no
longer reflect duties and responsibilities customary for an executive officer of
a publicly-traded company; provided, however, that NOVA's change to a privately-
                           --------  -------
held company (for example, as a result of acquisition) and the corresponding
change in Employee's duties and responsibilities shall not, by itself, be
sufficient to qualify as a "Responsibilities Breach"; (ii) Employee is required
to relocate to an office that is more than thirty-five (35) miles from
Employee's current office located at One Concourse Parkway, Suite 300, Atlanta,
Georgia  30328; (iii) there is a reduction in Employee's Base Salary payable
under Section 2, an adverse change in the terms of the Incentive Compensation
Plan, or a material reduction in benefits provided to Employee under Section 3
(whether occurring at once or over a period of time); or (iv) NOVA materially
breaches this Agreement, (each of (i), (ii), (iii) and (iv) being referred to as
a "Responsibilities Breach"), and NOVA fails to cure said Responsibilities
Breach within the Notice Period; provided, however, that with respect only to
                                 --------  -------
breaches that it is not possible to cure within the Notice Period, so long as
NOVA is diligently using its best efforts to cure such breaches within such
Notice Period, the Notice Period shall be automatically extended for an
additional period of time (not to exceed sixty (60) days) to enable NOVA to cure
such breaches, provided, further, that NOVA continues to diligently use its best
               --------  -------
efforts to cure such breaches. Notwithstanding anything to the contrary in this
Section 6(e), the Notice Period for any breach arising from the failure to pay
compensation shall be five (5) days.

          (f)  Employee may terminate this Agreement at any time, without cause,
upon thirty (30) days prior written notice to NOVA.

                                       4
<PAGE>

          (g)  NOVA may terminate this Agreement at any time, without cause,
upon written notice to Employee.

          (h)  This Agreement shall automatically renew for successive one (1)
year terms (each a "Renewal Term") unless either party hereto gives the other
party hereto written notice of its or her intent not to renew this Agreement no
later than one hundred eighty (180) days prior to the date the Initial Term, or
the then-current Renewal Term, is scheduled to expire. Employee's Employment
shall terminate upon termination or expiration of this Agreement.

     7.   Termination Payments.

          (a)  Upon termination of Employee's Employment, for whatever reason
(other than termination for "Cause" pursuant to Section 6(b), termination by
 ----- ----
Employee pursuant to Section 6(f), expiration of this Agreement following notice
of non-renewal by Employee pursuant to Section 6(h), or termination because
Employee otherwise "quits" or voluntarily terminates her employment other than
pursuant to Section 6(e) (each, a "Termination Exclusion")) (the effective date
of such termination or expiration being referred to as the "Termination Date"),
in addition to any amounts payable to Employee hereunder (including but not
limited to accrued but unpaid Base Salary), and any other benefits required to
be provided to Employee and her dependents under contract and applicable law:

               (i)  NOVA shall pay Employee in cash an amount equal to her
          "Annual Base Compensation" (as defined in Section 7(f)) multiplied by
          two (2) (the "Severance Payment"). The Severance Payment shall be paid
          in twenty-four (24) equal monthly installments, the first of which
          shall be made on the first day of the calendar month following the
          calendar month in which the Termination Date occurs; provided,
          however, that:

                    (A)  if Employee's Employment is terminated (other than by
               reason of a Termination Exclusion) within two (2) years after a
               Change in Control of NOVA, NOVA shall pay Employee the Severance
               Payment in one lump sum within thirty (30) days of the
               Termination Date.

                    (B)  if, within the two-year period immediately following a
               Change in Control of NOVA, Employee's Employment is terminated by
               Employee pursuant to Section 6(f), because Employee "quits" or
               voluntarily terminates her employment or this Agreement expires
               following notice of non-renewal by Employee pursuant to Section
               6(h), such a termination shall not be deemed to be a Termination
               Exclusion for purposes of this Section 7. Accordingly, NOVA shall
               pay Employee an amount equal to her Annual Base Compensation
               multiplied by two (2), and NOVA shall pay Employee this Severance
               Payment in one lump sum within thirty (30) days of the
               Termination Date; provided, however, in such a case, (i) Employee
               will not be paid any Supplemental Payment and (ii) Employee will
               not be entitled to her Bonus Compensation if such a terminating
               event occurs prior to the date when any accrued Bonus
               Compensation would be paid to Employee (even if she was employed
               for the entire calendar year upon which such Bonus Compensation
               would be calculated).

                    (C)  in the event Employee is terminated for Cause pursuant
               to the terms of Section 6(b), such event shall be governed by
               Section 7(b) hereof even if such Termination Date is within two
               (2) years after a Change in Control of NOVA.

                                       5
<PAGE>

               (ii)   NOVA shall pay Employee an amount (the "Supplemental
          Payment") equal to (x) the amount of Bonus Compensation payable to
          Employee for the calendar year immediately preceding the year in which
          the Termination Date occurs (the "Prior Bonus Amount") multiplied by
          (y) a fraction, the numerator of which is the number of days beginning
          on January 1/st/ of the calendar year in which the Termination Date
          occurs and ending on the Termination Date, and the denominator of
          which is 365. The Supplemental Payment shall be paid to Employee
          concurrently with the payment of the Prior Bonus Amount; provided,
          however, that if the Prior Bonus Amount has already been paid to
          Employee, the Supplemental Payment shall be paid within 30 days of the
          Termination Date. In the event the Termination Date occurs in the
          first calendar year of Employee's employment, then the Supplemental
          Payment shall equal the pro rata percentage (determined using the
          fraction above) of the Bonus Compensation Employee would have received
          for the calendar year in which the Termination Date occurred had
          Employee remained employed for the entire calendar year in which the
          Termination Date occurred, and the Supplemental Payment shall be paid
          to Employee concurrently with NOVA's payment of Bonus Compensation
          generally for such calendar year.

               (iii)  Notwithstanding any provision to the contrary in the NOVA
          Corporation Deferred Compensation Plan (the "Deferred Compensation
          Plan"), the Deferred Compensation Plan Administrative Committee will
          exercise its sole option and sole discretion pursuant to Sections 7.02
          and 9.02 of the Deferred Compensation Plan, and will determine that
          Employee shall become fully vested immediately in all of her Deferred
          Compensation Plan accounts as of the Termination Date.

               (iii)  Notwithstanding any provision to the contrary in any other
          agreement or document (including but not limited to NOVA's applicable
          plan documents), all stock options, restricted stock and other similar
          rights that, as of the Termination Date, have been granted to Employee
          shall become vested and exercisable immediately upon notice of such
          termination and, as provided under the applicable plan or agreement,
          Employee shall have the right to exercise any or all of such rights.
          Further, in the event Employee's Employment is terminated for whatever
          reason (other than termination for "Cause" pursuant to Section 6(b))
          within two (2) years after a Change in Control of NOVA, Employee shall
          have the continuing right to exercise the "Qualified Options" (as
          defined in Section 7(f)(iv)), at any time prior to the date which is
          one (1) year after the Termination Date (without regard to any
          provision thereof requiring earlier expiration upon termination of
          employment).

               (iv)   Until the earlier to occur of (x) the expiration of the
          Severance Period or (y) Employee becomes an employee of another
          company providing Employee and her dependents with medical, life and
          disability insurance (the period from the Termination Date until such
          event being referred to herein as the "Continuation Period"), NOVA
          shall provide to Employee and her dependents the coverage for the
          benefits described in Sections 3(a), (b) and (c); provided, however,
          such coverage shall not be provided to the extent that such coverage
          is generally provided through an insurance contract with a licensed
          insurance company and such insurance company will not agree to insure
          for such coverage.

     During the two (2) year period following the Termination Date (the
     "Severance Period"), Employee shall comply with the non-disclosure
     obligations and covenants not to solicit or compete set forth in Sections
     10 and 11 below.

                                       6
<PAGE>

     Except as provided in Section 7(a)(i)(B), for purposes of this Section
     7(a), any accrued but unpaid Bonus Compensation shall be paid to Employee
     on the date that Bonus Compensation would have been payable under the
     Incentive Compensation Plan had termination of Employee's Employment not
     occurred.

          (b)  In the event Employee's Employment is terminated as a result of
the Termination Exclusions identified in Section 7(a), Employee shall be paid
her accrued but unpaid Base Salary through the Termination Date, and any other
benefits required to be provided to Employee and her dependents under contract
and applicable law. Employee will not be entitled to her Bonus Compensation if
Employee's Employment is terminated as a result of one of the Termination
Exclusions prior to the date when any earned Bonus Compensation would be paid to
Employee. In such a case, Employee shall not be entitled to any portion of her
Bonus Compensation upon such termination of employment even if she was employed
for the entire calendar year upon which such Bonus Compensation would be
calculated.

          (c)  In the event Employee's Employment is terminated as a result of
one of the Termination Exclusions identified in Section 7(a), NOVA, at its sole
option and its sole discretion and at any time within thirty (30) days of the
Termination Date, may cause Employee to be obligated to comply with the non-
disclosure obligations and covenants not to solicit or compete set forth in
Sections 10 and 11 below for a period of one (1) or two (2) years following the
Termination Date, as set forth below:

               (i)  By giving notice to Employee at any time within thirty (30)
          days of the Termination Date of its intent to exercise the "One Year
          Option" herein described, NOVA may cause Employee to be obligated to
          comply with the non-disclosure obligations and covenants not to
          solicit or compete set forth in Sections 10 and 11 below for a period
          of one (1) year following the Termination Date; provided, however,
          that NOVA shall pay Employee an aggregate amount in cash equal to
          Employee's then Base Salary in effect immediately prior to the
          Termination Date multiplied by one (1) (the "One Year Payment").  The
          One Year Payment shall be paid by NOVA to Employee in twelve (12)
          equal monthly payments, the first of which shall be made on the first
          day of the calendar month following the calendar month in which the
          Termination Date occurs.  In the event NOVA exercises the One Year
          Option, the one (1) year period following the Termination Date shall
          be deemed the "Exclusion Period";

               (ii) By giving notice to Employee any time within thirty (30)
          days of the Termination Date of its intent to exercise the "Two Year
          Option" herein described, NOVA may cause Employee to be obligated to
          comply with the non-disclosure obligations and covenants not to
          solicit or compete set forth in Sections 10 and 11 below for a period
          of two (2) years following the Termination Date; provided, however,
          that NOVA shall pay Employee an aggregate amount in cash equal to
          Employee's Base Salary in effect immediately prior to the Termination
          Date multiplied by two (2) (the "Two Year Payment"). The Two Year
          Payment shall be paid by NOVA to Employee in twenty-four (24) equal
          monthly payments, the first of which shall be made on the first day of
          the calendar month following the calendar month in which the
          Termination Date occurs. In the event NOVA exercises the Two Year
          Option, the two (2) year period following the Termination Date shall
          be deemed the "Exclusion Period".

          (d)  In the event of the death of Employee, all benefits and
compensation hereunder shall, unless otherwise specified by Employee, be payable
to, or exercisable by, Employee's estate.

          (e)  Gross-Up Payment.

                                       7
<PAGE>

               (i)  Anything in this Agreement to the contrary notwithstanding,
          in the event it shall be determined that any payment or distribution
          by or on behalf of NOVA to or for the benefit of Employee as a result
          of a "Change in Control" or as otherwise payable under Sections 3(h)
          or 7(a) (whether paid or payable or distributed or distributable
          pursuant to the terms of this Agreement or otherwise, but determined
          without regard to any additional payments required under this Section
          7(e) (a "Payment")) would be subject to the excise tax imposed by
          Section 4999 of the Internal Revenue Code of 1986, as amended (the
          "Code"), or any interest or penalties are incurred by Employee with
          respect to such excise tax (such excise tax, together with any such
          interest and penalties, are hereinafter collectively referred to as
          the "Excise Tax"), then Employee shall be entitled to receive an
          additional payment (a "Gross-Up Payment") in an amount such that,
          after payment by Employee of all taxes upon the Gross-Up Payment (such
          taxes including, without limitation, any income taxes and Excise Tax
          imposed upon the Gross-Up Payment, and any interest or penalties
          imposed with respect to such taxes), Employee retains an amount of the
          Gross-Up Payment equal to the Excise Tax imposed upon the Payment.

               (ii) Subject to the provisions of Section 7(e)(iii), all
          determinations required to be made under this Section 7, including
          whether and when a Gross-Up Payment is required and the amount of such
          Gross-Up Payment and the assumptions to be utilized in arriving at
          such determination, shall be made by a nationally recognized
          accounting firm or law firm selected by Employee and reasonably
          acceptable to NOVA (the "Tax Firm"); provided, however, that the Tax
                                               --------  -------
          Firm shall not determine that no Excise Tax is payable by Employee
          unless it delivers to Employee a written opinion (the "Accounting
          Opinion") that failure to pay the Excise Tax and to report the Excise
          Tax and the payments potentially subject thereto on or with Employee's
          applicable federal income tax return will not result in the imposition
          of an accuracy-related or other penalty on Employee.  All fees and
          expenses of the Tax Firm shall be borne solely by NOVA.  Within
          fifteen (15) business days of the receipt of notice from Employee that
          there has been a Payment, the Tax Firm shall make all determinations
          required under this Section 7, shall provide to NOVA and Employee a
          written report setting forth such determinations, together with
          detailed supporting calculations, and, if the Tax Firm determines that
          no Excise Tax is payable, shall deliver the Accounting Opinion to
          Employee.  Any Gross-Up Payment, as determined pursuant to this
          Section 7, shall be paid by NOVA to Employee within fifteen (15) days
          of the receipt of the Tax Firm's determination.  Subject to the
          remainder of this Section, any determination by the Tax Firm shall be
          binding upon NOVA and Employee; provided, however, that Employee shall
          only be bound to the extent that the determinations of the Tax Firm
          hereunder, including the determinations made in the Accounting
          Opinion, are reasonable and reasonably supported by applicable law.
          As a result of the uncertainty in the application of Section 4999 of
          the Code at the time of the initial determination by the Tax Firm
          hereunder, it is possible that Gross-Up Payments which will not have
          been made by NOVA should have been made ("Underpayment"), consistent
          with the calculations required to be made hereunder.  In the event
          that it is ultimately determined in accordance with the procedures set
          forth in Section 7(e)(iii) that Employee is required to make a payment
          of any Excise Tax, the Tax Firm shall reasonably determine the amount
          of the Underpayment that has occurred and any such Underpayment shall
          be promptly paid by NOVA to or for the benefit of Employee. In
          determining the reasonableness of Tax Firm's determinations hereunder,
          and the effect thereof, NOVA and Employee shall be provided a
          reasonable opportunity to review such determinations with Tax Firm and
          their respective tax counsel, if separate from the Tax Firm. Tax
          Firm's determinations

                                       8
<PAGE>

          hereunder, and the Accounting Opinion, shall not be deemed reasonable
          until Employee's reasonable objections and comments thereto have been
          satisfactorily accommodated by Tax Firm.

               (iii)  Employee shall notify NOVA in writing of any claims by the
          Internal Revenue Service that, if successful, would require the
          payment by NOVA of the Gross-Up Payment. Such notification shall be
          given as soon as practicable, but no later than thirty (30) calendar
          days after Employee actually receives notice in writing of such claim,
          and shall apprise NOVA of the nature of such claim and the date on
          which such claim is requested to be paid; provided, however, that the
                                                    --------  -------
          failure of Employee to notify NOVA of such claim (or to provide any
          required information with respect thereto) shall not affect any rights
          granted to Employee under this Section except to the extent that NOVA
          is materially prejudiced in the defense of such claim as a direct
          result of such failure.  Employee shall not pay such claim prior to
          the expiration of the thirty (30) day period following the date on
          which she gives such notice to NOVA (or such shorter period ending on
          the date that any payment of taxes with respect to such claim is due).
          If NOVA notifies Employee in writing prior to the expiration of such
          period that it desires to contest such claim, Employee shall do all of
          the following:

                      (A)  give NOVA any information reasonably requested by
               NOVA relating to such claim;

                      (B)  take such action in connection with contesting such
               claim as NOVA shall reasonably request in writing from time to
               time, including, without limitation, accepting legal
               representation with respect to such claim by an attorney selected
               by NOVA and reasonably acceptable to Employee;

                      (C)  cooperate with NOVA in good faith in order
               effectively to contest such claim;

                      (D)  if NOVA elects not to assume and control the defense
               of such claim, permit NOVA to participate in any proceedings
               relating to such claim; provided, however, that NOVA shall bear
               and pay directly all costs and expenses (including additional
               interest and penalties) incurred in connection with such contest
               and shall indemnify and hold Employee harmless, on an after-tax
               basis, for any Excise Tax or income tax (including interest and
               penalties with respect thereto) imposed as a result of such
               representation and payment of costs and expenses. Without
               limiting the foregoing provisions of this Section 7, NOVA shall
               have the right, at its sole option, to assume the defense of and
               control all proceedings in connection with such contest, in which
               case it may pursue or forego any and all administrative appeals,
               proceedings, hearings and conferences with the taxing authority
               in respect of such claim and may either direct Employee to pay
               the tax claimed and sue for a refund or contest the claim in any
               permissible manner, and Employee agrees to prosecute such contest
               to a determination before any administrative tribunal, in a court
               of initial jurisdiction and in one or more appellate courts, as
               NOVA shall determine; provided, however, that if NOVA directs
                                     --------  -------
               Employee to pay such claim and sue for a refund, NOVA shall
               advance the amount of such payment to Employee, on an interest-
               free basis and shall indemnify and hold Employee harmless, on an
               after-tax basis, from any Excise Tax or income tax (including
               interest or penalties with respect thereto) imposed with respect
               to such advance or with respect to any imputed

                                       9
<PAGE>

               income with respect to such advance; and further provided that
               any extension of the statute of limitations relating to payment
               of taxes for the taxable year of Employee with respect to which
               such contested amount is claimed to be due is limited solely to
               such contested amount. Furthermore, NOVA's right to assume the
               defense of and control the contest shall be limited to issues
               with respect to which a Gross-Up Payment would be payable
               hereunder and Employee shall be entitled to settle or contest, as
               the case may be, any other issue raised by the Internal Revenue
               Service or any other taxing authority.

               (iv) If, after the receipt by Employee of an amount advanced by
          NOVA pursuant to this Section 7(e), Employee becomes entitled to
          receive any refund with respect to such claim, Employee shall (subject
          to NOVA's complying with the requirements of Section 7(e)(iii))
          promptly pay to NOVA the amount of such refund (together with any
          interest paid or credited thereon after taxes applicable thereto).
          If, after the receipt by Employee of an amount advanced by NOVA
          pursuant to Section 7(e)(iii), a determination is made that Employee
          is not entitled to a refund with respect to such claim and NOVA does
          not notify Employee in writing of its intent to contest such denial of
          refund prior to the expiration of thirty (30) days after such
          determination, then such advance shall, to the extent of such denial,
          be forgiven and shall not be required to be repaid and the amount of
          forgiven advance shall offset, to the extent thereof, the amount of
          Gross-Up Payment required to be paid.

          (f)  For purposes of this Agreement, the following terms shall be
defined as follows:

               (i)  "Change in Control" shall mean:

                    (A)  The acquisition (other than from NOVA) by any person,
               entity or "group", within the meaning of Section 13(d)(3) or
               14(d)(2) of the Securities Exchange Act of 1934 (the "Exchange
               Act") (excluding, for this purpose, any employee benefit plan of
               NOVA or its subsidiaries which acquires beneficial ownership of
               voting securities of NOVA) of beneficial ownership (within the
               meaning of Rule 13d-3 promulgated under the Exchange Act) of 25%
               or more of either the then outstanding shares of NOVA Stock or
               the combined voting power of NOVA's then outstanding voting
               securities entitled to vote generally in the election of
               directors; or

                    (B)  The consummation by NOVA of a reorganization, merger,
               consolidation, in each case, with respect to which the shares of
               NOVA voting stock outstanding immediately prior to such
               reorganization, merger or consolidation do not constitute or
               become exchanged for or converted into more than 50% of the
               combined voting power entitled to vote generally in the election
               of directors of the reorganized, merged or consolidated company's
               then outstanding voting securities, or a liquidation or
               dissolution of NOVA or of the sale of all or substantially all of
               the assets of NOVA; and

                    (C)  The failure for any reason of individuals who
               constitute the Incumbent Board to continue to constitute at least
               a majority of the board of directors of (i) NOVA, if NOVA remains
               a publicly-traded company, or (ii) the ultimate parent company,
               if NOVA becomes a direct or indirect subsidiary of another
               company.

                                       10
<PAGE>

               (i.e., either (A) and (C) or (B) and (C) must occur in order to
               constitute a Change in Control for purposes of this definition).

               Notwithstanding the foregoing definition, a leverage buyout
               transaction whereby NOVA becomes a privately-held company and the
               management of NOVA obtains an equity interest in NOVA or its
               successor as part of such transaction shall not constitute a
               Change in Control for purposes of this Agreement.

               (ii)  "Annual Base Compensation" means the greater of (x)
          Employee's Base Salary in effect on the Termination Date, or (y) the
          greatest Base Salary in effect during the calendar year immediately
          prior to the calendar year in which the Termination Date occurs.

               (iii) "Incumbent Board" shall mean the members of the Board of
          Directors of NOVA as of the Effective Date hereof and any person
          becoming a member of the Board of Directors of NOVA hereafter whose
          election, or nomination for election by NOVA's shareholders, was
          approved by a vote of at least a majority of the directors then
          comprising the Incumbent Board (other than an election or nomination
          of an individual whose initial assumption of office is in connection
          with an actual or threatened election contest relating to the election
          of the directors of NOVA, as such terms are used in Rule 14a-11 of
          Regulation 14A promulgated under the Exchange Act).

               (iv)  "Qualified Options" shall mean all stock options,
          restricted stock, and other similar rights (a) granted to Employee
          prior to the date hereof (whether vested or unvested), that entitle
          Employee to acquire NOVA Stock for a price per share equal to or
          greater than $17.92; or (b) granted to Employee on or after the date
          of this Agreement.

     8.   Products, Notes, Records and Software. Employee acknowledges and
agrees that all memoranda, notes, records and other documents and computer
software created, developed, compiled, or used by Employee or made available to
her during the term of her Employment concerning or relative to the Business,
including, without limitation, all customer data, billing information, service
data, and other technical material of NOVA is and shall be NOVA's property.
Employee agrees to deliver without demand all such materials to NOVA within
three (3) days after the termination of Employee's Employment. Employee further
agrees not to use such materials for any reason after said termination.

     9.   Arbitration.

          (a)  NOVA and Employee acknowledge and agree that (except as
specifically set forth in Section 9(d)) any claim or controversy arising out of
or relating to this Agreement shall be settled by binding arbitration in
Atlanta, Georgia, in accordance with the National Rules of the American
Arbitration Association for the Resolution of Employment Disputes in effect on
the date of the event giving rise to the claim or controversy. NOVA and Employee
further acknowledge and agree that either party must request arbitration of any
claim or controversy within one (1) year of the date of the event giving rise to
the claim or controversy by giving written notice of the party's request for
arbitration. Failure to give notice of any claim or controversy within one (1)
year of the event giving rise to the claim or controversy shall constitute
waiver of the claim or controversy.

          (b)  All claims or controversies subject to arbitration pursuant to
Section 9(a) above shall be submitted to arbitration within six (6) months from
the date that a written notice of request for arbitration is effective. All
claims or controversies shall be resolved by a panel of three arbitrators who
are licensed to practice law in the State of Georgia and who are experienced in
the arbitration of labor and

                                       11
<PAGE>

employment disputes. These arbitrators shall be selected in accordance with the
National Rules of the American Arbitration Association for the Resolution of
Employment Disputes in effect at the time the claim or controversy arises.
Either party may request that the arbitration proceeding be stenographically
recorded by a Certified Shorthand Reporter. The arbitrators shall issue a
written decision with respect to all claims or controversies within thirty (30)
days from the date the claims or controversies are submitted to arbitration. The
parties shall be entitled to be represented by legal counsel at any arbitration
proceedings.

          (c)  NOVA and Employee acknowledge and agree that the arbitration
provisions in this Agreement may be specifically enforced by either party, and
that submission to arbitration proceedings may be compelled by any court of
competent jurisdiction. NOVA and Employee further acknowledge and agree that the
decision of the arbitrators may be specifically enforced by either party in any
court of competent jurisdiction.

          (d)  Notwithstanding the arbitration provisions set forth herein,
Employee and NOVA acknowledge and agree that nothing in this Agreement shall be
construed to require the arbitration of any claim or controversy arising under
Sections 10 and 11 of this Agreement nor shall such provisions prevent NOVA from
seeking equitable relief from a court of competent jurisdiction for violations
of Sections 10 and 11 of this Agreement. These provisions shall be enforceable
by any court of competent jurisdiction and shall not be subject to arbitration
except by mutual written consent of the parties signed after the dispute arises,
any such consent, and the terms and conditions thereof, then becoming binding on
the parties. Employee and NOVA further acknowledge and agree that nothing in
this Agreement shall be construed to require arbitration of any claim for
workers' compensation or unemployment compensation.

     10.  Nondisclosure.

          (a)  NOVA Confidential Information. Employee acknowledges and agrees
               -----------------------------
that because of her Employment, she will have access to proprietary information
of NOVA concerning or relative to the Business (collectively, "NOVA Confidential
Information") which includes, without limitation, technical material of NOVA,
sales and marketing information, customer account records, billing information,
training and operations information, materials and memoranda, personnel records,
pricing and financial information relating to the business, accounts, customers,
prospective customers, employees and affairs of NOVA, and any information marked
"Confidential" by NOVA. Employee acknowledges and agrees that NOVA Confidential
Information is and shall be NOVA's property. Employee agrees that during the
term of her Employment, Employee shall keep NOVA Confidential Information
confidential, and Employee shall not use NOVA Confidential Information for any
reason other than on behalf of NOVA pursuant to, and in strict compliance with,
the terms of this Agreement. Employee further agrees that during the Severance
Period or the Exclusion Period, as applicable, Employee shall continue to keep
NOVA Confidential Information confidential, and Employee shall not use NOVA
Confidential Information for any reason or in any manner.

          (b)  Notwithstanding the foregoing, Employee shall not be subject to
the restrictions set forth in subsection (a) of this Section 10 with respect to
information which:

               (i)   becomes generally available to the public other than as a
          result of disclosure by Employee or the breach of Employee's
          obligations under this Agreement;

               (ii)  becomes available to Employee from a source which is
          unrelated to her Employment or the exercise of her duties under this
          Agreement, provided that such source lawfully obtained such
          information and is not bound by a confidentiality agreement with NOVA;
          or

                                       12
<PAGE>

               (iii) is required by law to be disclosed.

          (c)  Trade Secrets. Employee acknowledges and agrees that because of
               -------------
her Employment, she will have access to "trade secrets" (as defined in the
Uniform Trade Secrets Act, O.C.G.A. (S) 10-1-760, et seq. (the "Uniform Trade
                                                  -- ---
Secrets Act") of NOVA ("Trade Secrets"). Nothing in this Agreement is intended
to alter the applicable law and remedies with respect to information meeting the
definition of "trade secrets" under the Uniform Trade Secrets Act, which law and
remedies shall be in addition to the obligations and rights of the parties
hereunder.

     11.  Covenants Not to Solicit or Compete.

     Employee acknowledges and agrees that, because of her Employment, she does
and will continue to have access to confidential or proprietary information
concerning merchants, associate banks and ISOs of NOVA and shall have
established relationships with such merchants, associate banks and ISOs as well
as with the vendors, consultants, and suppliers used to service such merchants,
associate banks and ISOs. Employee agrees that during the term of her Employment
and continuing throughout the Severance Period or the Exclusion Period, as
applicable, Employee shall not, directly or indirectly, either individually, in
partnership, jointly, or in conjunction with, or on behalf of, any person, firm,
partnership, corporation, or unincorporated association or entity of any kind:

          (a)  compete with NOVA in providing credit card and debit card
transaction processing services within the Territory or otherwise associate
with, obtain any interest in (except as a shareholder holding less than five
percent (5%) interest in a corporation traded on a national exchange or
over-the-counter), advise, consult, lend money to, guarantee the debts or
obligations of, or perform services in either a supervisory or managerial
capacity or as an advisor, consultant or independent contractor for, or
otherwise participate in the ownership, management, or control of, any person,
firm, partnership, corporation, or unincorporated association of any kind which
is providing credit card and debit card transaction processing services within
the Territory;

          (b)  solicit or contact, for the purpose of providing products or
services the same as or substantially similar to those provided by NOVA in
connection with the Business, any person or entity that during the term of
Employee's Employment was a merchant, associate bank, ISO or customer (including
any actively-sought prospective merchant, associate bank, ISO or customer) of
NOVA and with whom Employee had material contact or about whom Employee learned
material information during the last twelve (12) months of her Employment;

          (c)  persuade or attempt to persuade any merchant, associate bank,
ISO, customer, or supplier of NOVA to terminate or modify such merchant's,
associate bank's, ISO's, customer's, or supplier's relationship with NOVA if
Employee had material contact with or learned material information about such
merchant, associate bank, ISO, customer or supplier during the last twelve (12)
months of her Employment; or

          (d)  persuade or attempt to persuade any person who (i) was employed
by NOVA as of the date of the termination of Employee's Employment and (ii) is
in a sales or management position with NOVA at the time of such contact, to
terminate or modify her employment relationship, whether or not pursuant to a
written agreement, with NOVA, as the case may be.

     12.  New Developments.  Any discovery, invention, process or improvement
made or discovered by Employee during the term of her Employment in connection
with or in any way affecting or relating to the Business (as then carried on or
under active consideration) shall forthwith be disclosed to NOVA and shall
belong to and be the absolute property of NOVA; provided, however, that this

                                       13
<PAGE>

provision does not apply to an invention for which no equipment, supplies,
facility, trade secret information of NOVA was used and which was developed
entirely on Employee's own time, unless (a) the invention relates (i) directly
to the Business or (ii) to NOVA's actual or demonstrably anticipated research or
development; or (b) the invention results from any work performed by Employee
for NOVA.

     13.  Remedy for Breach.  Employee acknowledges and agrees that her breach
of any of the covenants contained in Sections 8, 10, 11 and 12 of this Agreement
would cause irreparable injury to NOVA and that remedies at law of NOVA for any
actual or threatened breach by Employee of such covenants would be inadequate
and that NOVA shall be entitled to specific performance of the covenants in such
sections or injunctive relief against activities in violation of such sections,
or both, by temporary or permanent injunction or other appropriate judicial
remedy, writ or order, without the necessity of proving actual damages.  This
provision with respect to injunctive relief shall not diminish the right of NOVA
to claim and recover damages against Employee for any breach of this Agreement
in addition to injunctive relief.  Employee acknowledges and agrees that the
covenants contained in Sections 8, 10, 11 and 12 of this Agreement shall be
construed as agreements independent of any other provision of this or any other
contract between the parties hereto, and that the existence of any claim or
cause of action by Employee against NOVA, whether predicated upon this or any
other contract, shall not constitute a defense to the enforcement by NOVA  of
said covenants.

     14.  Reasonableness.  Employee has carefully considered the nature and
extent of the restrictions upon her and the rights and remedies conferred on
NOVA under this Agreement, and Employee hereby acknowledges and agrees that:

          (a)  the restrictions and covenants contained herein, and the rights
and remedies conferred upon NOVA, are necessary to protect the goodwill and
other value of the Business;

          (b)  the restrictions placed upon Employee hereunder are narrowly
drawn, are fair and reasonable in time and territory, will not prevent her from
earning a livelihood, and place no greater restraint upon Employee than is
reasonably necessary to secure the Business and goodwill of NOVA;

          (c)  NOVA is relying upon the restrictions and covenants contained
herein in continuing to make available to Employee information concerning the
Business; and

          (d)  Employee's Employment places her in a position of confidence and
trust with NOVA and its employees, merchants, associate banks, ISOs, customers,
vendors and suppliers.

     15.  Invalidity of Any Provision. It is the intention of the parties hereto
that the provisions of this Agreement shall be enforced to the fullest extent
permissible under the laws and public policies of each state and jurisdiction in
which such enforcement is sought, but that the unenforceability (or the
modification to conform with such laws or public policies) of any provision
hereof shall not render unenforceable or impair the remainder of this Agreement
which shall be deemed amended to delete or modify, as necessary, the invalid or
unenforceable provisions. The parties further agree to alter the balance of this
Agreement in order to render the same valid and enforceable. The terms of the
non-competition provisions of this Agreement shall be deemed modified to the
extent necessary to be enforceable and, specifically, without limiting the
foregoing, if the term of the non-competition is too long to be enforceable, it
shall be modified to encompass the longest term which is enforceable and, if the
scope of the geographic area of non-competition is too great to be enforceable,
it shall be modified to encompass the greatest area that is enforceable. The
parties further agree to submit any issues regarding such modification to a
court of competent jurisdiction if they are unable to agree and further agree
that if said court declines to so amend or modify this Agreement, the parties
will submit the issue of amendment or modification of the non-competition
covenants in this Agreement to binding arbitration in accordance

                                       14
<PAGE>

with the commercial arbitration rules then in effect of the American Arbitration
Association. Any such arbitration hearing will be held in Atlanta, Georgia, and
this Agreement shall be construed and enforced in accordance with the laws of
the State of Georgia, including this arbitration provision.

     16.  Full Settlement and Legal Expenses.  NOVA's obligation to make the
payments provided for in this Agreement and otherwise to perform its obligations
hereunder shall not be affected by any set-off, counter-claim, recoupment,
defense or other claim, right or action which NOVA may have against the Employee
or others.  In no event shall the Employee be obligated to seek other employment
or take any other action by way of mitigation of the amounts payable to the
Employee under any of the provisions of this Agreement.  NOVA agrees to pay, to
the full extent permitted by law, all legal fees and expenses which the Employee
may reasonably incur as a result of any legitimate, non-frivolous contest
(regardless of the outcome thereof) by NOVA or others of the validity or
enforceability of, or liability under, any provision of this Agreement or any
guarantee of performance thereof (including as a result of any legitimate, non-
frivolous contest by the Employee about the amount of any payment pursuant to
Section 7 of this Agreement), plus in each case interest at the applicable
federal rate provided for in Section 7872(f)(2) of the Code.  NOVA will not be
bound to pay any legal fees or expenses arising out of baseless, meritless or
frivolous contests brought hereunder by Employee or others.  A contest will be
deemed baseless, meritless and/or frivolous if a court or other arbiter assesses
penalties or sanctions for bringing said contest, or a court or other arbiter
dismisses said contest for failure to state a colorable claim.

     17.  Applicable Law. This Agreement shall be construed and enforced in
accordance with the laws of the State of Georgia.

     18.  Waiver of Breach. The waiver by NOVA of a breach of any provision of
this Agreement by Employee shall not operate or be construed as a waiver of any
subsequent breach by Employee.

     19.  Successors and Assigns.  This Agreement shall inure to the benefit of
NOVA, its subsidiaries and affiliates, and their respective successors and
assigns.  This Agreement is not assignable by Employee but shall be freely
assignable by NOVA.

     20.  Notices. All notices, demands and other communications hereunder shall
be in writing and shall be delivered in person or deposited in the United States
mail, certified or registered, with return receipt requested, as follows:

parties, and supersedes all other prior negotiations, commitments, agreements
and understandings (written or oral) between the parties with respect to the
subject matter hereof, including but not limited to the Prior Agreement, which
is hereby terminated. It may not be changed orally but only by an agreement in
writing signed by the party against whom enforcement of any waiver, change,
modification, extension, or discharge is sought.

     22.  Indemnification.  At all times during and after Employee's Employment
and the effectiveness of this Agreement, NOVA shall indemnify Employee (as a
director, officer, employee and otherwise) to the fullest extent permitted by
law and shall at all times maintain appropriate provisions in its Articles of
Incorporation and Bylaws which mandate that NOVA provide such indemnification.

     23.  Survival.  The provisions of Sections 7, 8, 9, 10, 11, 12, 13, 14, 15,
16, 17, 20, 22, 23 and 24 shall survive termination of Employee's Employment and
termination of this Agreement.

     24.  Withholding.  All payments required to be made by NOVA under this
Agreement will be subject to the withholding of such amounts, if any, relating

Section 7(e).

                                   EXHIBIT A
                                   ---------

                     Annual Incentive Compensation Schedule

*    Payment of annual incentive compensation (the "Bonus Payment") to be based
     upon relative achievement of Targeted Net Income (as defined).

*    Net Income is Net Income determined in accordance with GAAP as determined
     from the annual audited Financial Statements, as adjusted to exclude non-
     operating gains and losses.

*    Targeted Net Income will be established annually by the Board of Directors.

*    The Bonus Payment will be calculated by following the steps outlined below:

     (1)  Determining the percentage equivalent to a fraction, the numerator of
          which is Net Income and the denominator of which is Targeted Net
          Income (such percentage being referred to as the "Actual/Targeted
          Ratio").

     (2)  Values will be calculated based on (A) through (E):

          (A)  For each full percentage point (up to 84%) by which the
                   ----
               Actual/Targeted Ratio equals or exceeds 80%, a value of 1% will
               be awarded.

          (B)  For each full percentage point (up to 89%) by which the
                   ----
               Actual/Targeted Ratio exceeds 84%, a value of 2% will be awarded.

          (C)  For each full percentage point (up to 94%) by which the
                   ----
               Actual/Targeted Ratio exceeds 89%, a value of 3% will be awarded.

          (D)  For each full percentage point (up to 99%) by which the
                   ----
               Actual/Targeted Ratio exceeds 94%, a value of 4% will be awarded.

          (E)  For each full percentage point (up to 150%) by which the
                   ----
               Actual/Targeted Ratio exceeds 100%, a value of 1% will be
               awarded. (note:  for this purpose, no value will be awarded for
                         ----
               equaling 100%).

     (3)  The sum of the values calculated in (A) through (E) (the "Bonus
          Percentage") shall be multiplied by Employee's then current Base
          Salary to yield the Bonus Payment.
     Examples:
     ---------

     .    If the Actual/Targeted Ratio is 92%, the Bonus Percentage would be
          29%. This is calculated by adding:

                     5%  (1% for 80-84% of Actual/Targeted Ratio)
               +    15%  (2% for 85-89% of Actual/Targeted Ratio)
               +     9%  (3% for 90-92% of Actual/Targeted Ratio)
                    ---------------------------------------------
                    29%

          Employee's Bonus Payment would be equal to Employee's then-current
          Base Salary multiplied by 29%.

                                       18
<PAGE>

     .    If the Actual/Targeted Ratio is 112%, the Bonus Percentage would be
          62%. This is calculated by adding:

                     5%  (1% for 80-84% of Actual/Targeted Ratio)
               +    10%  (2% for 85-89% of Actual/Targeted Ratio)
               +    15%  (3% for 90-94% of Actual/Targeted Ratio)
               +    20%  (4% for 95-99% of Actual/Targeted Ratio)
               +     0%  (0% for 100% of Actual/Targeted Ratio)
               +    12%  (1% for 101-112% of Actual/Targeted Ratio)
                    -----------------------------------------------
                    62%

          Employee's Bonus Payment would be equal to Employee's then-current
          Base Salary multiplied by 62%.

*    The foregoing notwithstanding, in order for any bonus to be payable with
     respect to any calendar year, the "Revenue" (as defined below) for such
     calendar year must equal or exceed 105% of the Revenue for the immediately
     preceding calendar year.  "Revenue" means revenue of NOVA determined in
     accordance with GAAP as determined from the annual audited Financial
     Statements, as adjusted to exclude non-operating items.

*    Notwithstanding anything to the contrary in this Agreement, in order to
     receive Bonus Compensation for any calendar year, Employee must be employed
     by NOVA on the last day of such calendar year.
