terms of                     this Agreement or otherwise (collectively, the Total
Benefits) and                     (ii) any of the Total Benefits will be subject to
the excise tax imposes                     pursuant to Section 4999 of the Internal
Revenue Code (Excise Tax),                     which tax may be imposed if
the payments made to Employee are deemed to be                     excess parachute
payments within the meaning of Section 280G of the                     Code, then
Employer shall pay to employee an additional amount (the                     Gross-Up
Payment) such that the net amount retained by Employee,                     after
deduction of any Excise Tax on the Total Benefits and any federal, state
                    and local income taxes, Excise Tax, and FICA and Medicare withholding
taxes upon                     the payment provided for by this Section, will be equal to
the Total Benefits so                     that Employee shall be, after payment of all
taxes, in the same financial                     position as if no taxes under Section
4999 had been imposed upon him. For                     purposes of this Section,
Employee will be deemed to pay federal income taxes at                     the highest
marginal rate of federal income taxation in the calendar year in
                    which the Excise tax is (or would be) payable and state and local
income taxes                     at the highest marginal rate of taxation in the state
and locality of                     Employees residence on the Date of Termination,
net of the reduction in                     federal income taxes that could be obtained
from the deduction of such state and                     local taxes (calculated by
assuming that any reduction under Section 68 of the                     Internal revenue
Code in the amount of itemized deductions allowable to Employee
                    applies first to reduce the amount of such state and local income
taxes that                     would otherwise be deductible by Employee).
| | --- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

expenses incurred to                enforce the provisions of this Agreement.
| | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

ownership           of any work product and all associated rights exclusively in the
Company. The           Company shall have the right to adapt, change, revise, delete
from, add to           and/or rearrange the work product or any part thereof written or
created by           Employee, and to combine the same with other works to any extent,
and to change           or substitute the title thereof, and in this connection Employee
hereby waives           the moral rights of authors as that term is commonly
understood           throughout the world including, without limitation, any similar
rights or           principles of law which Employee may now or later have by virtue of
the law of           any locality, state, nation, treaty, convention or other source.
Unless           otherwise specifically agreed, Employee shall not be entitled to any
additional           compensation, beyond his or her salary, for any exercise by the
Company of its           rights set forth in the preceding sentence.

11.     
          Severability

| | It
is the intention of the parties that if any of the restrictions or covenants contained
herein is held to cover a geographic area or to be for a length of time or to apply to
business activities which is not permitted by applicable law, or in any way construed to
be too broad or to any extent invalid, such provision shall not be construed to be null,
void and of no effect, but to the extent such provision would be valid or enforceable
under applicable law, a court of competent jurisdiction shall construe and interpret or
reform this Section to provide for a covenant having the maximum enforceable geographic
area, time period and any other provisions (not greater than those contained herein) as
shall be valid and as shall be valid and enforceable under such applicable law.
| | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | If
any provision contained in this Section shall for any reason be held invalid, illegal or
unenforceable in any respect, such invalidity, illegality or unenforceability shall not
affect any other provisions of this Section, but this Section shall be construed as if
such invalid, illegal or unenforceable provision had never been contained herein.
| | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

12.     Waiver of Provisions

| | Failure
of either party to insist, in one or more instances, on performance by the other in
strict accordance with the terms and conditions of this Agreement shall not be deemed a
waiver or relinquishment of any right granted hereunder or of the future performance of
any such term or condition or of any other term of condition of this Agreement, unless
such waivers contained in a writing signed by the party against whom the waiver or
relinquishment is sought to be enforced.
| | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

13.     Notices

| | Any
notice or other communication to a party required or permitted hereunder shall be in a
writing and shall be deemed sufficiently given when received by the party (regardless of
the method of delivery), or if sent by registered or certified mail, postage and fees
prepaid, addressed to the party as follows, on the third business day after mailing:
| | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

|(a) | If to Employer:          3130 Gateway Drive
|--- | -------------------------------------------
|    | Norcross, GA 30071                         

|(b) | If to Employee:          1350 Treebrook Court
|--- | ---------------------------------------------
|    | Roswell, Georgia 30075                       

|or
in each case to such other address as the party may time to time designate in writing to
the other party.
|------------------------------------------------------------------------------------------------------------

14.     Governing Law

| | This
Agreement shall be governed by and construed and enforced in accordance with the laws of
the State of Georgia.
| | -------------------------------------------------------------------------------------------------------------------

15.     
          Enforcement

| | In
the event of any breach or threatened breach by Employee of any covenant contained in
Sections 9 or 10 hereof, the resulting injuries to the Company would be difficult or
impossible to estimate accurately, even though irreparable injury or damages would
certainly result. Accordingly, an award of legal damages, if without other relief, would
be inadequate to protect the Company. Employee, therefore, agrees that in the event of
any such breach, the Company shall be entitled to obtain from a court of competent
jurisdiction an injunction to restrain the breach or anticipated breach of any such
covenant, and to obtain any other available legal, equitable, statutory, or contractual
relief. Should the Company have cause to seek such relief, no bond shall be required from
the Company, and Employee shall pay all attorneys fees and court costs which the
Company may incur to the extent the Company prevails in its enforcement action.
