5.  Administration  

    This Plan shall be administered by the Board. The Board, acting in its absolute discretion, shall exercise such powers and take such action as expressly called
for under this Plan. The Board shall have the power to interpret this Plan and, subject to Section 17, to take such other action in the administration and operation of the Plan as it deems
equitable under the circumstances. The Board's actions shall be binding on the Company, on each affected Employee or Key Person, and on each other person directly or indirectly affected by such
action. 

    The
Board may delegate its authority under the Plan, in whole or in part, to a Committee appointed by the Board consisting of not less than two (2) members. The Committee (if
appointed) shall act according to the policies and procedures set forth in the Plan and to those policies and procedures established by the Board, and the Committee shall have such powers and
responsibilities as 

2

 

are set forth by the Board. Reference to the Board in this Plan shall specifically include reference to the Committee where the Board has delegated its authority to the Committee, and any action by
the Committee pursuant to a delegation of authority by the Board shall be deemed an action by the Board under the Plan. Notwithstanding the above, the Board may assume the powers and responsibilities
granted to the Committee at any time, in whole or in part. 

6.  Eligibility  

    Except as provided below, only Employees shall be eligible for the grant of Options or Restricted Stock under this Plan, but no Employee shall have the right
to be granted an Option or Restricted Stock under this Plan merely as a result of his or her status as an Employee. Key Persons may be eligible, subject to written approval by the Board, for the grant
of Options or Restricted Stock under this Plan, but only if the Key Person has provided valuable services to the Company, a Subsidiary or a Parent and only if the Option granted to such Key Person is
a Non-ISO. 

7.  Grant Of Options  

    The Board, in its absolute discretion, shall grant Options under this Plan from time to time to purchase Shares and shall have the right to grant new Options
in exchange for outstanding Options. The Committee, if appointed, and acting pursuant the procedures established by the Board, may either grant Options under the Plan or recommend to the Board that
Options be granted under the Plan.
Options shall be granted to Employees or Key Persons selected by the Board and neither the Board nor the Committee (if appointed) shall be under any obligation whatsoever to grant Options to all
Employees or Key Persons or to grant all Options subject to the same terms and conditions. Each grant of an Option shall be evidenced by a Stock Option Grant, and each Stock Option Grant shall: 

	1.
	specify
whether the Option is an ISO or Non-ISO; and

	2.
	incorporate
such other terms and conditions as the Board, acting in its absolute discretion, deems consistent with the terms of this Plan, including (without limitation) a
restriction on the number of Shares subject to the Option which first become exercisable or subject to surrender during any calendar year. 

    In
determining Employee(s) or Key Person(s) to whom an Option shall be granted and the number of Shares to be covered by such Option, the Board may take into account the
recommendations of the President of the Company and its other officers, the duties of the Employee or Key Person, the present and potential contributions of the Employee or Key Person to the success
of the Company, the anticipated number of years of service remaining before the attainment by the Employee of retirement age and other factors deemed relevant by the Board, in its sole discretion, in
connection with accomplishing the purpose of this Plan. An Employee or Key Person who has been granted an Option to purchase Shares of the Company, whether under this Plan or otherwise may be granted
one or more additional Options. 

    If
the Board grants an ISO and a Non-ISO to an Employee on the same date, the right of the Employee to exercise or surrender one such Option shall not be conditioned on
his or her failure to exercise or surrender the other such Option. 

8.  Option Price  

    If an Option is an ISO, the Option Price for each Share subject to such Option shall be no less than the Fair Market Value of a Share on the date such Option
is granted or, if such Option is granted to a Ten Percent Shareholder, the Option Price for each Share subject to such Option shall be no less than 110% of the Fair Market Value of a Share on the date
such Option is granted. If an Option is a Non-ISO, the Option Price for each Share shall be no less than the minimum price required by 

3

 

applicable state law or by the Company's governing instrument, whichever price is greater. The Option Price shall be payable in full upon the exercise of any Option, and a Stock Option Grant at the
discretion of the Board can provide for the payment of the Option Price either in cash or in Shares
acceptable to the Board or in any combination of cash and Shares acceptable to the Board. Any payment made in Shares shall be treated as equal to the Fair Market Value of such Shares on the date the
properly endorsed certificate for such Shares is delivered to the Board (or to its delegate). 

    Notwithstanding
the above, and in the sole discretion of the Board, an Option may be exercised as to a portion or all (as determined by the Board) of the number of Shares specified in
the Stock Option Grant by delivery to the Company of a promissory note to be executed by the Optionee. The promissory note shall include, along with such other terms and conditions as the Board shall
determine, provisions in a form approved by the Board under which (1) the balance of the aggregate purchase price shall be payable in equal installments over such period and shall bear interest
at such rate (which shall not be less than the prime bank loan rate as determined by the Board) as the Board shall approve and (2) the Optionee shall be personally liable for payment of the
unpaid principal balance and all accrued but unpaid interest. 

9.  Exercise Period  

    Each Option granted under this Plan shall be exercisable in whole or in part at such time or times as set forth in the related Stock Option Grant, but no Stock
Option Grant shall: 

	1.
	make
an Option exercisable before the date such Option is granted or;

	2.
	make
an Option exercisable after the earlier of the: 
	a)
	the
date such Option is exercised in full; or

	b)
	the
date which is the tenth (10th) anniversary of the date such Option is granted, if such Option is a Non-ISO or an ISO granted to a non-Ten Percent
Shareholder, or the date which is the fifth (5th) anniversary of the date such Option is granted, if such Option is an ISO granted to a Ten Percent Shareholder. 

    A
Stock Option Grant may provide for the exercise of an Option after the employment of an Employee or Key Person has terminated for any reason whatsoever including death or
disability. 

10. Nontransferability  

    No Option granted under this Plan shall be transferable by an Employee or Key Person other than by will or by the laws of descent and distribution, and such
Option shall be exercisable during an Employee's or Key Person's lifetime only by the Employee or Key Person, as the case may be. The person or persons to whom an Option is transferred by will or by
the laws of descent and distribution thereafter shall be treated as the Employee or Key Person. 

11. Surrender Of Options  

	11.1
	General Rule.  The Board acting in its absolute discretion may incorporate a provision in a Stock Option Grant to allow an Employee
or Key Person to surrender his or her Option in whole or in part in lieu of the exercise in whole or in part of that Option on any date that: 
	1.
	the
Fair Market Value of the Shares subject to such Option exceeds the Option Price for such Shares; and

	2.
	the
Option to purchase such Shares is otherwise exercisable. 

	11.2
	Procedure.  The surrender of an Option in whole or in part shall be effected by the delivery of the Stock Option Grant to the Board
(or to its delegate) together with a statement signed by the Employee or Key Person which specifies the number of Shares ("Surrendered Shares") as 

4

 

to
which the Employee or Key Person surrenders his or her Option and how he or she desires payment be made for such Surrendered Shares. 

	11.3
	Payment.  An Employee or Key Person in exchange for his or her Surrendered Shares shall receive a payment in cash or in Shares, or
in a combination of cash and Shares, equal in amount on the date such surrender is effected to the excess of the Fair Market Value of the Surrendered Shares on such date over the Option Price for the
Surrendered Shares. The Board acting in its absolute discretion can approve or disapprove an Employee's or Key Person's request for payment in whole or in part in cash and can make that payment in
cash or in such combination of cash and Shares as the Board deems appropriate. A request for payment only in Shares shall be approved and made in Shares to the extent payment can be made in whole
shares of Shares and (at the Board's discretion) in cash in lieu of any fractional Shares.

	11.4
	Restrictions.  Any Stock Option Grant which incorporates a provision to allow an Employee or Key Person to surrender his or her
Option in whole or in part also shall incorporate such additional restrictions on the exercise or surrender of such Option as the Board deems necessary to satisfy the conditions to the exemption under
Rule 16b-3 (or any successor exemption) to Section 16(b) of the Exchange Act. 

12. Restricted Stock Grants  

    The Board of Directors, or the Committee if so appointed pursuant to Section 5, may grant to Employees and Key Persons Shares of the Company's Common
Stock, subject to such restrictions as the Board of Directors, in its sole discretion, deems appropriate. Such restrictions may include, but shall not be limited to, restrictions upon exercise,
vesting provisions, and purchase provisions with respect to price and time of repurchase. Grant of all Restricted Stock shall be accompanied by a Restricted Stock Agreement which shall be executed and
accepted by the Grantee in order for the Restricted Stock Grant to become effective. 

13. Securities Registration  

    Each Stock Option Grant and Restricted Stock Grant may provide that, upon the receipt of Shares as a result of the surrender or exercise of an Option or the
grant of Restricted Stock, the Employee or Key Person shall, if so requested by the Company, hold such Shares for investment and not with a view of resale or distribution to the public and, if so
requested by the Company, shall deliver to the Company a written statement satisfactory to the Company to that effect. Each Stock Option Grant and Restricted Stock Grant also may provide that, if so
requested by the Company, the Employee or Key Person shall make a written representation to the Company that he or she will not sell or offer to sell any of such Shares unless a registration statement
shall be in effect with respect to such Shares under the Securities Act of 1933, as amended ("1933 Act") and any applicable state securities law or unless he or she shall have furnished to the Company
an opinion, in form and substance satisfactory to the Company, of legal counsel acceptable to the Company, that such registration is not required. Certificates representing the Shares transferred upon
the exercise or surrender of an Option granted under this Plan or a Restricted Stock Grant may at the discretion of the Company bear a legend to the effect that such Shares have not been registered
under the 1933 Act or any applicable state securities law and that such Shares may not be sold or offered for sale in the absence of an effective registration statement as to such Shares under the
1933 Act and any applicable state securities law or an opinion, in form and substance satisfactory to the Company, of legal counsel acceptable to the Company, that such registration is not required.

   14. Life Of Plan  

    No Option shall be granted under this Plan on or after the earlier of: 

	1.
	the
tenth (10th) anniversary of the effective date of this Plan (as determined under Section 4 of this Plan), in which event this Plan otherwise thereafter shall continue in
effect until all outstanding Options have been surrendered or exercised in full or no longer are exercisable; or

	2.
	the
date on which all of the Shares reserved under Section 3 of this Plan have (as a result of the surrender or exercise of Options granted under this Plan) been issued or no
longer are available for use under this Plan, in which event this Plan also shall terminate on such date. 

    No
Restricted Stock Grant shall be made under this Plan on or after the tenth (10th) anniversary of the effective date of the Plan, in which case the Plan otherwise shall continue in
effect until the later of (i) all restrictions on Shares transferred as Restricted Stock Grants have lapsed or (ii) no Shares of Restricted Stock remain outstanding. 

15. Adjustment  

    The number of Shares reserved under Section 3 of this Plan and the number of Shares subject to Options granted under this Plan and the Option Price of
such Options shall be adjusted by the Board in an equitable manner to reflect any change in the capitalization of the Company, including, but not limited to, such changes as stock dividends or stock
splits. Furthermore, the Board shall have the right to adjust (in a manner which satisfies the requirements of Section 424(a) of the Code) the number of Shares reserved under Section 3
of this Plan and the number of Shares subject to Options granted under this Plan and the Option Price of such Options in the event of any corporate transaction described in Section 424(a) of
the Code which provides for the substitution or assumption of such Options. If any adjustment under this Section 15 creates a fractional Share or a right to acquire a fractional Share, such
fractional Share shall be disregarded and the number of Shares reserved under this Plan and the number subject to any Options granted under this Plan shall be the next lower number of Shares, rounding
all fractions downward. An adjustment made under this Section 15 by the Board shall be conclusive and binding on all affected persons and, further, shall not constitute an increase in the
number of Shares reserved under Section 3 of this Plan. 

16. Sale Or Merger Of The Company  

    If the Company agrees to sell substantially all of its assets for cash or property or for a combination of cash and property or agrees to any merger,
consolidation, reorganization, division or other transaction in which Shares are converted into another security or into the right to receive securities or property and such agreement does not provide
for the assumption or substitution of the Options granted under this Plan, each Option at the direction and discretion of the Board, or as is otherwise provided in the Option Agreements, may be
canceled unilaterally by the Company in exchange for the whole Shares (or, subject to satisfying the conditions to the exemption under Rule 16b-3 or any successor exemption to
Section 16(b) of the Exchange Act, for the whole Shares and the cash in lieu of a fractional Share) which each Employee or Key Person otherwise would receive if he or she had the right to
surrender his or her outstanding Option in full under Section 11 of this Plan and he or she exercised that right exclusively for Shares on a date fixed by the Board which comes before such sale
or other corporate transaction. 

17. Amendment Or Termination  

    This Plan may be amended by the Board from time to time to the extent that the Board deems necessary or appropriate; provided, however, no such amendment shall
be made absent the approval of 

6

 

the shareholders of the Company (1) to increase the number of Shares reserved under Section 3, except as set forth in Section 15, (2) to extend the maximum life of the Plan
under Section 14 or the maximum exercise period under Section 9, (3) to decrease the minimum Option Price under Section 8, or (4) to change the designation of
Employees or Key Persons eligible for Options under Section 6. The Board also may suspend the granting of Options or Restricted Stock Grants under this Plan at any time and may terminate this
Plan at any time; provided, however, the Company shall not have the right to modify, amend or cancel any Option or Restricted Stock granted before such suspension or termination unless (i) the
Employee or Key Person consents in writing to such modification, amendment or cancellation or (ii) there is a dissolution or liquidation of the Company or a transaction described in
Section 15 or Section 16 of this Plan. 

18. Change Of Control  

    A "Change of Control" of the Company shall be deemed to have occurred if one of the following events takes place: 

	1.
	Any
person other than an Existing Person becomes a holder of record, as reflected on the stock transfer ledger of the Company, of securities of the Company representing a right of
the person, acting individually and not in concert with any other party (and not acting through a contract, arrangement, understanding, relationship, proxy, voting trust, voting agreement, or other
device), to vote more than fifty percent (50%) of the combined voting power of the Company's then outstanding securities;

	2.
	A
person other than an Existing Person obtains the right to elect a majority of the members of the Board of Directors of the Company;

	3.
	The
Company or any of its subsidiaries shall sell, assign or otherwise transfer, directly or indirectly, assets (including stock or other securities of subsidiaries, but other than
the grant of licenses to intangible assets in the ordinary course of business) having a fair market value of sixty-six percent (66%) or more of all the assets of the Company and its
subsidiaries to any third party, other than a wholly-owned subsidiary of the Company;

	4.
	Any
person becomes a beneficial owner (as such term is used in Rule 13d-3 under the Securities Exchange Act of 1934, as amended (the "Exchange Act")) of
securities of the Company representing a right to vote more than fifty percent (50%) of the Company's then outstanding securities, other than an Existing Person; or

	5.
	Any
transaction or series of related transactions occurring within a period of ninety (90) days, pursuant to, following or as a result of; which the beneficial ownership of
fifty percent (50%) or more of the common stock of the Company (or other securities having generally the right to vote for election of the Board of Directors) shall be sold, assigned or otherwise
transferred, directly or indirectly, to any person or persons other than an Existing Person, whether by sale or issuance of common stock or other securities or otherwise. 

    Notwithstanding
the above, in determining the percentages of ownership described in 1. through 5. above, the issuance of new securities pursuant to a public offering of the common
stock of the Company under the Securities Act of 1933, as amended, and the issuance of new securities in connection with the exercise of warrants and options granted and outstanding as of the
effective date of the Plan or which are granted pursuant to a public offering referenced above, shall not be taken into consideration in determining whether a Change of Control has occurred. In
addition, a Change of Control shall not, solely with respect to Subsection 3. above, be deemed to occur as a result of any conveyance, transfer or grant to a bank or other financial institution of a
collateral assignment of; securities title to or security interest in any goods, accounts, inventory, general intangibles or other assets of the Company or any of its subsidiaries to secure the
obligations of the Company or any of its 

7

 

subsidiaries to such bank or other financial institution, or the exercise of any rights or remedies by such bank or other financial institution relation thereto. For purposes of this Agreement, an
"Existing Person" means a shareholder or holder of any option or warrant of the Company as of the effective date of the Plan or any lineal descendant or antecedent, father, mother, spouse, brother, or
sister of such shareholder or option holder or a trustee for the benefit of any of the foregoing. 

19. Miscellaneous  

	19.1
	Shareholder Rights.  No Employee or Key Person shall have any rights as a shareholder of the Company as a result of the grant of an
Option to him or to her under this Plan or his or her exercise or surrender of such Option pending the actual delivery of Shares subject to such Option to such Employee or Key Person.

	19.2
	No Contract of Employment.  The grant of an Option or Restricted Stock to an Employee or Key Person under this Plan shall not
constitute a contract of employment or other association with the Company, and shall not confer on an Employee or Key Person any rights upon his or her termination of employment or other association
with the Company, in addition to those rights, if any, expressly set forth in the Stock Option Grant or Restricted Stock Grant which evidences his or her Option or Restricted Stock.

	19.3
	Withholding.  The exercise or surrender of any Option granted under this Plan shall constitute an Employee's or Key Person's full
and complete consent to whatever action the Board directs to satisfy the federal and state tax withholding requirements, if any, which the Board in its discretion deems applicable to such exercise or
surrender.

	19.4
	Transfer.  The transfer of an Employee between or among the Company, a Subsidiary or a Parent shall not be treated as a termination
of his or her employment under this Plan.

	19.5
	Construction.  This Plan shall be construed under the laws of the State of Georgia.

    2.  Restrictions on Exercise.  

    (a)  Securities Restrictions.  This Option may not be exercised unless such exercise is in compliance

    3.  Termination of Option.  Except as provided below in this Section, this Option may not be exercised
after the date on which Optionee ceases to perform services for the Company or any Parent or Subsidiary of the Company. Optionee shall be considered to perform services for the Company for all
purposes under this Section and Section 10 hereof, if Optionee is an officer or full-time employee of the Company or any Parent or Subsidiary of the Company or if the Board of
Directors determines that Optionee is rendering substantial services as a part-time employee, consultant, contractor or adviser to the Company or any Parent or Subsidiary of the Company.
The Board of Directors of the Company shall have discretion to determine whether Optionee has ceased to perform services for the Company or any Parent or Subsidiary of the Company and the effective
date on which such services cease (the "Termination Date"). 

    (a)  Termination Generally.  If Optionee ceases to perform services for the Company or any Parent or
Subsidiary of the Company for any reason except death or disability, this Option shall be forfeited after thirty (30) days after Optionee ceases to perform such services, along with any and all
rights or subsequent rights attached thereto effective on the day following the Termination Date, but in no event later than the Expiration Date.

Termination Date, but in no event later than the Expiration Date. 

    (c)  Cancellation for Non-Compliance.  This Option may be canceled by the Company if Optionee
is in breach of the terms of Section 6(d) of the Exercise Agreement (defined below), which terms are hereby incorporated in this Option. Failure to comply with the applicable provisions of
Section 6(d) of the Exercise Agreement during the periods 

specified therein, shall also entitle the Company to rescind any exercise of this Option.

continue in the employ of, or other relationship with, the Company or any Parent or Subsidiary of the Company or limit in any way the right of the Company or any Parent or Subsidiary of the Company to
terminate Optionee's employment or other relationship at any time, with or without cause. 

    4.  Manner of Exercise.  

    (a)  Exercise Agreement.  This Option shall be exercisable by delivery to the Company of an executed
Exercise Agreement and Employee Shareholder Agreement ("Exercise Agreement") in the form of the Exercise Agreement delivered to Optionee, if applicable, or in such other form as may be approved or
accepted by the Company, which shall set forth Optionee's election to exercise some or all of this Option, the number of Shares being purchased, any restrictions imposed on the Shares and such other
representations and agreements as may be required by the Company to comply with applicable securities laws. 

    (b)  Exercise Price.  Such notice shall be accompanied by full payment of the Exercise Price for the
Shares being purchased. Payment for the Shares may be made in U.S. dollars in cash (by check) or, where permitted by law and approved by the Board in its sole discretion: (i) by cancellation of
indebtedness of the Company to Optionee; (ii) by surrender of shares of Common Stock of the Company that have been owned by Optionee for more than six (6) months (and which have been
paid for within the meaning of SEC Rule 144 and, if such Shares were purchased from the Company by use of a promissory note, such note has been fully paid with respect to such Shares), or were
obtained by the Optionee in the open public market, having a Fair Market Value equal to the exercise price of the Option; (iii) by instructing the Company to withhold Shares otherwise issuable
pursuant to an exercise of the Option having a Fair Market Value equal to the exercise price of the Option (including the withheld Shares); (iv) by waiver of compensation accrued by Optionee
for services rendered; (v) a combination of the foregoing; or (vi) such other means of payment as is approved by the Board of Directors. 

    (c)  Withholding Taxes.  Prior to the issuance of the Shares upon Exercise of this Option, Optionee must
pay or make adequate provision for any applicable federal or state withholding obligations of the Company. Where approved by the Board, the Optionee may provide for payment of withholding taxes upon
exercise of the Option by requesting that the Company retain Shares with a Fair Market Value equal to the minimum amount of taxes required to be withheld. In such case, the Company shall issue the net
number of Shares to the Optionee by deducting the Shares retained from the Shares exercised. 

    (d)  Issuance of Shares.  Provided that such notice and payment are in form and substance satisfactory to
counsel for the Company, the Company shall cause the Shares to be issued in the name of Optionee or Optionee's legal representative. 

    5.  Notice of Disqualifying Disposition of ISO Shares.  If the Option granted to Optionee herein is an
ISO, and if Optionee sells or otherwise disposes of any of the Shares acquired pursuant to the ISO on or before the later of (a) the 

date two years after the date of grant, or (b) the date one year after exercise of the ISO with respect to the Shares to be sold or disposed, the Optionee shall immediately notify the Company
in writing of such disposition. Optionee acknowledges and agrees that Optionee may be subject to income tax withholding by the Company on the compensation income recognized by the Optionee from any
such early disposition by payment in cash or out of the current wages or other earnings payable to the Optionee. 

    6.  Nontransferability of Option.  This Option may not be transferred in any manner other than by will or
by the laws of descent and distribution and may be exercised during the lifetime of the Optionee only by the Optionee. The terms of this Option shall be binding upon the executor, administrators,
successors and assigns of the Optionee. 

    7.  Tax Consequences.  OPTIONEE UNDERSTANDS THAT THE GRANT AND EXERCISE OF THIS OPTION, AND THE SALE OF
SHARES OBTAINED THROUGH THE EXERCISE OF THIS OPTION, MAY HAVE TAX IMPLICATIONS THAT COULD RESULT IN ADVERSE TAX CONSEQUENCES TO OPTIONEE. OPTIONEE REPRESENTS THAT OPTIONEE HAS CONSULTED WITH OR WILL
CONSULT WITH HIS OR HER TAX ADVISOR, AND OPTIONEE FURTHER ACKNOWLEDGES THAT OPTIONEE IS NOT RELYING ON THE COMPANY FOR ANY TAX ADVICE. 

    8.  Interpretation.  Any dispute regarding the interpretation of this Stock Option Grant shall be
submitted by Optionee or the Company to the Company's Board of Directors thereof that administers the Plan, which shall review such dispute at its next regular meeting. The resolution of such a
dispute by the Board shall be final and binding on the Company and an Optionee. 

    9.  Entire Agreement.  The Plan and the Exercise Agreement are incorporated herein by this reference.
Optionee acknowledges and agrees that the granting of this Option constitutes a full accord, satisfaction and release of all obligations or commitments made to Optionee by the Company or any of its
officers, directors, shareholders or affiliates with respect to the issuance of any securities or rights to acquire securities, of the Company or any of its affiliates. This Option, the Plan and the
Exercise Agreement constitute the entire agreement of the parties hereto and supersede all prior undertakings and agreements with respect to the subject matter hereof. 

    10.  Vesting and Exercise of Shares.  Subject to the terms of the Plan, this Option and the Exercise
Agreement, the Shares issued pursuant to the exercise of this Option shall be subject to the vesting restrictions on the attached Vesting Schedule. For purposes of such vesting, "Continuous Service"
means a period of continuous performance of services by Optionee for the Company, a Parent, or a Subsidiary, as determined by the Board.

    The
Company and Optionee hereby agree as follows: 

    1.  Purchase of Shares.  On this date and subject to the terms and conditions of this Exercise Agreement,
Optionee hereby exercises the Stock Option Grant between the Company and Optionee dated as of the "Date of Stock Option Grant" set forth above (the "Option"), with respect to the "Number of Shares
Purchased" set forth above of the Company's common stock at the "Aggregate Purchase Price" set forth above (the "Purchase Price") and the "Price per Share" set forth above (the "Purchase Price Per
Share"). Optionee hereby delivers to the Company the Aggregate Purchase Price, by cash or check (or such other form of payment satisfactory to the Company as provided in the Stock Option Grant),
receipt of which is acknowledged by the Company. The term "Shares" refers to the shares of the Company's common stock purchased under this Exercise Agreement, and includes all securities received
(a) in replacement of the Shares and (b) as a result of stock dividends or stock splits in respect of the Shares. Capitalized terms used in this Exercise Agreement that are not defined
herein have the definitions ascribed to them in the Plan or the Option. 

    2.  Representations of Purchaser.  Optionee represents and warrants to the Company that: 

	(a)
	Optionee
acknowledges that Optionee has received, read and understands the Plan and the Option and agrees to abide by and be bound by their terms and conditions.

	(b)
	Optionee
is purchasing the Shares for Optionee's own account for investment purposes only and not with a view to, or for sale in connection with, a distribution of the Shares within
the meaning of the Securities Act of 1933, as amended (the "1933 Act").

	(c)
	Optionee
has no present intention of selling or otherwise disposing of all or any portion of the Shares.

	(d)
	Optionee
is fully aware of (i) the highly speculative nature of the investment in the Shares; (ii) the financial hazards involved; (iii) the lack of liquidity
of the Shares and the restrictions on transferability of the Shares (e.g., that Optionee may not be able to sell or dispose of the Shares or use them as collateral for loans); and (iv) that a
condition of the transfer of such Shares is Optionee's execution of any Shareholders Agreement referenced in Section 4. 

 

	(e)
	Optionee
is capable of evaluating the merits and risks of this investment, has the ability to protect Optionee's own interests in this transaction and is financially capable of
bearing a total loss of this investment. 

    3.  Compliance with Securities Laws. Optionee understands and acknowledges that the Shares have not been registered
under the 1933 Act and that, notwithstanding any other provision of the Option to the contrary, the exercise of any rights to purchase any Shares is expressly conditioned upon compliance with the 1933
Act and all applicable state securities laws. Optionee agrees to cooperate with the Company to ensure compliance with such laws. 

    4.  Contractual Restrictions on Transfer. Optionee agrees that as a condition to Optionee's right to exercise this
Option and acquire the Shares so exercised, such Shares shall be subject to the restrictions of Sections 5 and 6 below and any Shareholders Agreement which the Board of Directors requests that the
Optionee execute in connection with such exercise (a "Shareholders Agreement"). No Shares may be issued pursuant to the execution of this Exercise Agreement under the Option unless and until the
Optionee has executed any such Shareholders Agreement or such other agreement provided by the Board. 

    5.  Company's Right of First Refusal. In the event no Shareholder Agreement is required by the Board of Directors at the
time of the issuance of Shares upon the exercise of the Option, before any Shares held by Optionee or any transferee (either being sometimes referred to herein as the "Holder") may be sold or
otherwise transferred (including transfer by gift or operation of law), the Company shall have an assignable right of first refusal to purchase the Shares on the terms and conditions set forth in this
Section (the "Right of First Refusal"). 

	(a)
	Notice of Proposed Transfer.  The Holder of the Shares shall deliver to the Company a written notice (the "Notice")
stating: (i) the Holder's bona fide intention to sell or otherwise transfer such Shares; (ii) the name of each proposed purchaser or other transferee ("Proposed Transferee");
(iii) the number of Shares to be transferred to each Proposed Transferee; and (iv) the bona fide cash price or other consideration for which the Holder proposes to transfer the Shares
(the "Offered Price"); and the Holder shall offer to sell the Shares at the Offered Price to the Company.

	(b)
	Exercise of Right of First Refusal.  At any time within 60 days after receipt of the Notice, the Company or its
assignee may, by giving written notice to the Holder, elect to purchase any or all of the Shares proposed to be transferred to any one or more of the Proposed Transferees, at the purchase price
determined in accordance with Subsection (c) below.

	(c)
	Purchase Price.  The purchase price for the Shares purchased under this Section shall be the Offered Price. If the
Offered Price includes consideration other than cash, the cash equivalent value of the non-cash consideration shall be determined by the Board of Directors of the Company in good faith.

	(d)
	Payment.  Payment of the purchase price shall be made, at the option of the Company or its assignee, either
(i) in cash (by check), by cancellation of all or a portion of any outstanding indebtedness of the Holder to the Company or such assignee, or by any combination thereof within thirty
(30) days after receipt of the Notice or (ii) in the manner and at the time(s) set forth in the Notice.

	(e)
	Holder's Right to Transfer.  If all of the Shares proposed in the Notice to be transferred to a given Proposed
Transferee are not purchased by the Company and/or its assignee as provided in this Section 5, then the Holder may sell or otherwise transfer such Shares to that Proposed Transferee at the
Offered Price or at a higher price, provided that such sale or other transfer is consummated within one hundred and twenty (120) days after the date of the Notice and provided further that any
such sale or other transfer is effected in accordance with any 

2

 

applicable
securities laws and the Proposed Transferee agrees in writing that the provisions of this Section shall continue to apply to the Shares in the hands of such Proposed Transferee. If the
Shares described in the Notice are not transferred to the Proposed Transferee within such period, a new Notice shall be given to the Company, and the Company shall again be offered the Right of First
Refusal, before any Shares held by the Holder may be sold or otherwise transferred. 

	(f)
	Exception for Certain Family Transfers.  Anything to the contrary contained in this Section notwithstanding, the
transfer of any or all of the Shares, during the Optionee's lifetime or on Optionee's death by will or intestacy, to Optionee's immediate family or a trust for the benefit of Optionee or Optionee's
immediate family shall be exempt from the provisions of this Section; provided that, as a condition to receiving the Shares, the transferee or other recipient shall agree in writing to receive and
hold the Shares so transferred subject to the provisions of this Agreement, and to transfer such Shares no further except in accordance with the terms of this Agreement. As used herein, "immediate
family" shall mean spouse, lineal descendant or antecedent, father, mother, brother or sister.

	(g)
	Termination of Right of First Refusal.  The Right of First Refusal shall terminate as to any Shares ninety
(90) days after the first sale of common stock of the Company to the general public pursuant to a registration statement filed with and declared effective by the Securities and Exchange
Commission (other than a registration statement solely covering an employee benefit plan or corporate reorganization). 

    6.  Company's Repurchase Option.  The Company shall also have an assignable option to repurchase all or a
portion of the Shares on the terms and conditions set forth in this Section (the "Repurchase Option") if Optionee should cease to be employed by the Company or to serve as a member of the Board of
Directors for any reason, or no reason, including without limitation Optionee's death, disability, voluntary resignation or termination by the Company with or without cause. 

	(a)
	Right of Termination Unaffected.  Nothing in this Agreement shall be construed to limit or otherwise affect in any
manner whatsoever the right or power of the Company to terminate Optionee's employment or association with the Company at any time, for any reason or no reason, with or without cause. For purposes of
this Agreement, Optionee shall be considered to be employed by the Company
or associated with the Company if Optionee is an officer, director or full-time employee of the Company or any Parent or Subsidiary of the Company or if the Board of Directors determines
that Optionee is rendering substantial services as a part-time employee, consultant, contractor or advisor to the Company or any parent or subsidiary of the Company. The Board of Directors
of the Company shall have discretion to determine whether Optionee has ceased to be employed by or associated with the Company or any Parent or Subsidiary and the effective date on which such
employment or association is terminated (the "Termination Date").

	(b)
	Exercise of Repurchase Option.  At any time on or before the first anniversary of the Termination Date, the Company
may elect to repurchase any or all of the Shares by giving Optionee written notice of exercise of the Repurchase Option.

	(c)
	Calculation of Repurchase Price.  If Optionee's employment with the Company is terminated for Cause (as defined
below), the repurchase price shall be the lower of (i) the Book Value Per Share (as defined below) or (ii) the Purchase Price Per Share. In all other circumstances, the repurchase price
shall equal the Book Value Per Share.

	(d)
	Noncompetition.  In acknowledgment of the benefits received by Optionee through the Grant and receipt of the Shares,
the Optionee agrees to refrain, within the United States, from engaging in any Competing Business (as defined below), directly or indirectly, on the 

3

 

Optionee's
own behalf or in the service or on behalf of others as a principal, partner, officer, director, manager, supervisor, administrator, consultant or employee, while an employee of the Company
and for a period ending one (1) year from the Optionee's Termination Date. In the event that the Board of Directors of the Company determines that the Optionee has violated the provisions of
this Section, then notwithstanding any other provisions contained in this Agreement, any Shares issued to Optionee by reason of Optionee's exercise of the Option shall be immediately canceled and the
Company shall refund to Optionee with respect to such Shares, the lesser of (i) the Purchase Price Per Share or (ii) the Book Value Per Share. 

	(e)
	Payment of Repurchase Price.  The repurchase price shall be payable, at the option of the Company or its assignee, by
(i) check, (ii) by cancellation of all or a portion of any outstanding indebtedness of Optionee to the Company or such assignee, (iii) by delivery of a promissory note of the
Company payable in substantially equal monthly installments over a sixty (60) month period from the date of repurchase at an interest rate equal to the prime rate of Citibank at its principal
place of business in New York City, New York, or its successor as of the Termination Date, plus one percentage point (1.0%), or (iv) any combination of the above.

	(f)
	Termination of Repurchase Rights.  The Right of Repurchase shall terminate as to any Shares ninety (90) days
after the first sale of common stock of the Company to the general public pursuant to a registration statement filed with and declared effective by the Securities and Exchange Commission (other than a
registration statement solely covering an employee benefit plan or corporate reorganization).

	(g)
	Definitions.  The following terms are used herein as defined below:

	(A)
	"Cause" shall mean conduct amounting to (i) fraud or dishonesty against the Company, (ii) Optionee's willful
misconduct, repeated refusal to follow the reasonable directions of the Board of Directors of the Company, or knowing violation of law in the course of performance of the duties of Optionee's
employment with the Company, (iii) repeated absences from work without a reasonable excuse, (iv) repeated intoxication with alcohol or drugs while on the Company's premises during
regular business hours, (v) a conviction or plea of guilty or nolo contendere to a felony or a crime involving dishonesty, or (vi) a
breach or violation of the terms of any employment or other agreement to which Optionee and the Company are party.

	(B)
	"Competing Business" shall mean any person or entity engaged in the business of developing real-time computer hardware
and software programs which provide functionality comparable to the functionality of products marketed, developed, or under development by the Company prior to Optionee's Termination Date.

audited or unaudited balance sheet of the Company and the future paid in capital from the outstanding but not exercised stock option grants, by the sum of the number of shares of Common Stock of the
Company issued and outstanding and the number of outstanding but not exercised outstanding stock option grants as of the date of such balance sheet. 

    7.  Compliance with Federal and State Securities Laws. Optionee understands and acknowledges that, in reliance upon the
representations and warranties made by Optionee herein, the Shares have not been registered with the SEC under the 1933 Act, but have been issued under an exemption or exemptions from the registration
requirements of the 1933 Act which impose certain restrictions on Optionee's ability to transfer the Shares and have not been registered under any Georgia securities laws or the securities laws of any
other state. Optionee understands that Optionee may not transfer any 

4

 

Shares and the Shares must be held indefinitely unless such Shares are registered under the 1933 Act, the securities laws of Georgia and of any other state which may apply or unless, in the opinion of
counsel to the Company, an exemption from such registration is available. Optionee understands that only the Company may file a registration statement with the SEC or Georgia or any other state
and that
the Company is under no obligation to do so with respect to the Shares. Optionee has also been advised that an exemption from registration may not be available or may not permit Optionee to transfer
all or any of the Shares in the amounts or at the times proposed by Optionee. 

    8.  Legends; "Stop Transfer" Rights. Optionee understands and agrees that the certificate(s) representing the Shares
will bear legends in substantially the following form: 

"The
shares represented by this Certificate have not been registered under the Georgia Securities Act of 1973, as amended (the "Georgia Act"), or under any other state securities law or the Securities
Act of 1933, as amended (the "Federal Act"). These shares have been acquired for investment and may not be offered for sale, hypothecated, sold or transferred, nor will any assignee or transferee
thereof be recognized by the Corporation as having an interest in such shares, in the absence of (i) an effective registration statement with respect to the shares under the Federal Act, or an
opinion of counsel satisfactory to the Corporation that such registration is not required, and (ii) an effective registration statement with respect to the shares under the Georgia Act or under
any other applicable state securities laws, or an opinion of counsel satisfactory to the Corporation that such shares will be offered for sale, hypothecated, sold or transferred only in a transaction
which is exempt under, or otherwise in compliance with, the Georgia Act and any other applicable state securities laws. 

The
shares represented by this certificate are subject to the terms and conditions of that certain Exercise Agreement and Employee Shareholder Agreement executed between the Shareholder and the
Corporation, a copy of which is on file with the Corporation." 

    Optionee
understands and agrees that, in order to ensure compliance with the restrictions referred to herein, the Company may issue appropriate "stop transfer" instructions to its
transfer agent, if any, and that, if the Company transfers its own securities, it may make appropriate notations to the same effect in its own records. 

    9.  Tax Consequences. OPTIONEE UNDERSTANDS THAT OPTIONEE MAY SUFFER ADVERSE TAX CONSEQUENCES AS A RESULT OF OPTIONEE'S
PURCHASE OR DISPOSITION OF THE SHARES. OPTIONEE REPRESENTS THAT OPTIONEE HAS CONSULTED WITH ANY TAX CONSULTANT(S) OPTIONEE DEEMS ADVISABLE IN CONNECTION WITH THE PURCHASE OR DISPOSITION OF THE SHARES

MAY BE AMENDED FROM TIME TO TIME. 

    10. Escrow. As security for the faithful performance of this Agreement, Optionee agrees, immediately upon receipt of the
certificate(s) evidencing the Shares, to deliver such certificate(s) to the Secretary of
the Company or its designee ("Escrow Holder"), who is hereby appointed to hold such certificates) in escrow and to take all such actions and to effectuate all such transfers and/or releases of such
Shares as are in accordance with the terms of this Agreement. Optionee and the Company agree that Escrow Holder shall not be liable to any party to this Agreement (or to any other party) for any
actions or omissions unless Escrow Holder is grossly negligent relative thereto. The Escrow Holder may rely upon any letter, notice or other document executed by any signature reported to be genuine,
and may rely upon advice of counsel and obey any order of any court with respect to the transactions 

5

 

contemplated herein. The Shares shall be released from escrow upon termination of both the Right of First Refusal set forth in Section 5 and the Repurchase Option set forth in Section 6;
provided, however, that such release shall not affect the rights of the Company with respect to any pledge of Shares to the Company. Optionee hereby irrevocably constitutes and appoints Escrow Holder
as Optionee's agent and attorney-in-fact for the purpose of executing and delivering any and all documents necessary to transfer any Shares purchased hereunder to the Company
pursuant to the terms of this Agreement and to record such transfer on the books of the Company, such appointment being made with full power of substitution in the premises. 

    11. Market Standoff Agreement. In connection with any public offering of the Company's securities, and upon the written
request of the Company or the underwriters managing any underwritten offering of the Company's securities, Optionee agrees that Optionee shall not sell, make any short sale of, loan, grant any option
for the purchase of, or otherwise dispose of the Shares or a portion thereof (other than those included in the registration), without the prior written consent of the Company or the underwriters of
such securities offering, for a period of time not to exceed two hundred seventy (270) days from the effective date of such registration. 

    12. Forced Sale. Optionee agrees that if at any time the shareholders of the Company owning at least fifty percent (50%)
of the outstanding shares of Common Stock of the Company (the "Majority Shareholders") shall negotiate the disposition of fifty percent (50%) or more of the total outstanding Common Stock,
collectively, to an unaffiliated buyer ("Buyer"), then Optionee shall support such disposition (including casting any votes which Optionee may, directly or indirectly, have with respect to any Shares)
and, upon written request of the Majority Shareholders and Buyer, sell to Buyer the same percentage of Shares held by Optionee that the Majority Shareholders (as a group) negotiated to sell to Buyer
on the same terms, conditions, and price under which the Majority Shareholders have agreed to sell the Common Stock to Buyer. The right of first refusal in Section 5 hereof shall not apply to
dispositions under this Section 12. 

    13. Counterparts. This Agreement may be signed in multiple counterparts, each of which shall be an original but all of
which, when taken together, shall constitute one and same instrument. 

    14. Entire Agreement. The Plan and the Option are incorporated herein by reference. This Exercise Agreement, the Plan
and the Option constitute the entire agreement of the parties and supersede in
their entirety all prior undertakings and agreements of the Company and Optionee with respect to the subject matter hereof, and are governed by Georgia law except for that body of law pertaining to
conflict of laws.

                                 FIRST AMENDMENT
                        TO THE FIRST RESTATED AND AMENDED
                      PUBLIC SERVICE COMPANY OF NEW MEXICO
                             EXECUTIVE SAVINGS PLAN

         THIS FIRST AMENDMENT to the First Restated and Amended Public
Servcie Company of New Mexico Executive Savings Plan (the "Plan") is made by
the Public Service Company of New Mexico (the "Company"), effective January
1, 2002.

         WHEREAS, the Company adopted the Plan as of July 1, 1998 to allow
certain key employees to receive retirement savings contributions in excess
of the limits imposed on qualified retirement plans;

         WHEREAS, the Plan was amended and restated November 16, 2001;

         WHEREAS, Public Service Company of New Mexico reserves the right to
amend the Plan pursuant to Section 7.1 of the Plan; and

         WHEREAS, Public Service Company of New Mexico now desires to amend
the Plan to: (i) increase the group of eligible participants; and (ii) expand
distributions options.

         NOW, THEREFORE, Public Service Company of New Mexico does hereby
amend the Plan as follows:

1.       Article I of the Plan is hereby amended by the addition of a new
         Section 1.8A, to be placed immediately after Section 1.8, to read as
         follows:

                           1.8A "Distribution Election Form" means the election
                  form by which a Participant elects the manner in which his
                  accounts shall be distributed pursuant to Section 5.2(b).

2.       Section 2.2 of the Plan is hereby amended in its entirety to read as
         follows:

                  2.2 SELECTION OF PARTICIPANTS. Any employees of the Company or
                  an adopting affiliate who are Participants in the Plan on the
                  date of adoption of this amended and restated Plan document
                  will continue as such, subject to the provisions of Section
                  2.3. Effective January 1, 2002 (or such later date as may be
                  established by the Plan Administrator), any employee who is
                  classified as an "officer" of the Company or an adopting
                  affiliate, shall be a Participant. For this purpose, an
                  "officer" is someone who occupies the position of Vice
                  President or higher. The Plan Administrator, in the exercise
                  of its discretion, and with the concurrence of the Company
                  and/or its Board of Directors, may select as Participants any
                  other employees of the Company or an adopting affiliate who
                  the Plan Administrator concludes, in the exercise of its
                  discretion, are properly included in the top hat group. As
                  noted in Section 2.1, this Plan is intended to provide
                  benefits only to members of the top hat group. The Company has
                  determined that all of the current officers are properly
                  includible in the top hat group.

3.       Article II of the Plan is hereby amended by renumbering the existing
         Section 2.3 as Section 2.4 and inserting a new Section 2.3 to read as
         follows:

                  2.3 DISCONTINUANCE OF PARTICIPATION. As a general rule, once
                  an individual is a Participant, he will continue as such for
                  all future Plan Years until his retirement or other
                  termination of employment. The Plan Administrator shall
                  discontinue an individual's participation in the Plan if the
                  Plan Administrator concludes, in the exercise of its
                  discretion, that the individual is no longer properly included
                  in the top hat group. If an individual's participation is
                  discontinued, the individual will no longer be eligible to

                  make deferrals or receive credits under this Plan. The
                  individual will not be entitled to receive a distribution,
                  however, until the termination of his employment, unless the
                  Plan Administrator, in the exercise of its discretion, directs
                  that a distribution be made as of an earlier date, in which
                  case the individual's accounts shall be distributed on the
                  same basis as if the individual's employment had been
                  terminated. The Participant's accounts will continue to be
                  adjusted to reflect hypothetical investment earnings or losses
                  in accordance with Section 4.1 until the accounts are
                  distributed.

4.       Section 3.2(a) of the Plan is hereby amended in its entirety to read as
         follows:

                           (a) AMOUNT. Any Participant may elect to defer,
                  pursuant to a Supplemental Deferral Agreement, the receipt of
                  all or any portion (designated in whole percentages) of the
                  Compensation otherwise payable to him or her by the Company or
                  an adopting affiliate in any Plan Year. The Participant's
                  Supplemental Deferrals will begin only after the Participant
                  has made the maximum pre-tax contributions to the MESP that
                  are permitted under Section 402(g) of the Code or pursuant to
                  the terms of the MESP document.
                  The amount deferred pursuant to this paragraph (a) shall be
                  allocated to the Supplemental Deferral Account maintained for
                  the Participant for such Plan Year.

5.       Section 3.2(b) of the Plan is hereby amended in its entirety to read as
         follows:

                           (b) TIMING OF ELECTIONS. As a general rule, the
                  Supplemental Deferral Agreement shall be signed by the
                  Participant and delivered to the Benefits Department prior to
                  January 1 of the Plan Year in which the Compensation to be
                  deferred is otherwise payable to the Participant. The
                  Supplemental Deferral Agreement will indicate whether it is to
                  be effective for a single Plan Year or will remain in effect
                  until properly changed by the Participant. For the Plan Year
                  in which a Participant first becomes eligible to participate
                  in the Plan, the Participant may elect to make Supplemental
                  Deferrals from Compensation otherwise payable in the future
                  during the then current Plan Year by signing and delivering a
                  Supplemental Deferral Agreement within thirty (30) days after
                  the date on which he or she is notified by the Benefits
                  Department that he or she is eligible to participate. Any
                  election made by a Participant shall be irrevocable with
                  respect to the Plan Year covered by the election. A
                  Participant may, however, revoke the election for any later
                  Plan Year by delivering to the Benefits Department a written
                  instrument prior to the beginning of the Plan Year for which
                  such revocation is to be effective.

6.       Section 3.3(a) of the Plan is hereby amended in its entirety to read as
         follows:

                           (a) SUPPLEMENTAL MATCHING CREDIT. Participants are
                  not permitted to make deferrals pursuant to Section 3.2(a)
                  until they have made the maximum pre-tax contributions to the
                  MESP that are permitted under Section 402(g) of the Code or
                  the terms of the MESP. This Plan is intended to put
                  participants in the same position that they would have been in
                  but for these limits on pre-tax contributions. Accordingly,
                  the Supplemental Matching Credit shall be in an amount equal
                  to the "lost MESP Matching Contribution." The "lost MESP
                  Matching Contribution" is the MESP Matching Contribution that
                  would have been due under the MESP if the deferrals under
                  Section 3.2 for the Plan Year could have been contributed,
                  instead, to the MESP. Supplemental Matching Credits are
                  subject, however, to the MESP's limits on the maximum matching
                  contribution for which Participants are eligible (currently,
                  6% of Compensation).

7.       Section 5.2 of the Plan is hereby amended in its entirety to read as
         follows:

                  5.2      FORM OF DISTRIBUTION.

                           (a) COMPANY STOCK FUND. Subject to Sections 5.2(c)
                  and 5.4, the portion of a Participant's accounts that is
                  allocated to the Company Stock Fund shall be distributed in a
                  single lump sum payment in whole shares of Company Stock (with
                  fractional shares paid for in cash) unless the Participant
                  elects to receive a cash distribution. The election to receive
                  cash or Company Stock shall be made at the time and in the
                  manner provided in the form prescribed by the Benefits
                  Department from time to time for that purpose. Any election
                  made by a Participant pursuant to this Section with respect to
                  a distribution from the Company Stock Fund shall be subject to
                  all applicable securities law requirements, including but not
                  limited to, Rule 16b-3. Any election that may not be
                  implemented due to the lack of any available exemption shall
                  be void. The Benefits Department may then make the
                  distribution in any fashion that will not result in a
                  violation of any applicable securities law requirements. The
                  Benefits Department also may delay the distribution if
                  necessary. An exemption to the securities law requirements
                  that is only available with the prior approval of the Board,
                  the shareholders, or some other individual or individuals,
                  shall not be considered to be available unless such approval
                  is actually granted in a timely manner.

                           (b) NON-COMPANY STOCK INVESTMENT FUNDS. Subject to
                  Section 5.2(c), the portion of a Participant's accounts that
                  is not allocated to the Company Stock Fund shall be
                  distributed in cash in a single lump sum payment,
                  installments, or in the form of an annuity. Installments and
                  annuity distributions shall be subject to such uniform rules
                  and procedures as may be adopted by the Plan Administrator
                  from time to time. The method of payment shall be selected by
                  the Participant in the initial Distribution Election Form
                  (which may be contained in a Supplemental Deferral Agreement)
                  submitted by the Participant to the Benefits Department on
                  entry into the Plan or following the adoption of this amended
                  and restated Plan, whichever is later. A Participant may
                  change his distribution election by filing a new Distribution
                  Election Form with the Benefits Department. A revised
                  Distribution Election Form will be honored only if at least
                  one year elapses between (1) the date on which such new
                  Distribution Election Form is filed with the Benefits
                  Department and (2) the date on which the Participant
                  terminates employment with the Company. If a revised
                  Distribution Election Form is not honored because it was not
                  timely filed, distributions shall be made pursuant to the most
                  recent Distribution Election Form filed by the Participant at
                  least one year prior to the Participant's termination. If no
                  valid Distribution Election Form exists (or if the only valid
                  form was filed within the one year period described above),
                  the Participant's accounts will be distributed in a single
                  lump sum.

                           (c) LIMITATIONS ON DISTRIBUTIONS AND INTRA-FUND
                  TRANSFERS. Amounts transferred pursuant to Section 4.2(c) to
                  or from the Company Stock Fund shall, for a one-year period,
                  continue to be subject to the distribution elections
                  applicable to such amounts (as adjusted for earnings or
                  losses) pursuant to Sections 5.2(a) and (b) as if no transfer
                  had taken place. For example, if a Participant transfers
                  $25,000 to the Company Stock Fund from other Investment Funds
                  on January 1, 2002, then that transferred $25,000, as adjusted
                  for subsequent earnings or losses, shall continue to be
                  distributable in cash pursuant to the distribution method
                  elected pursuant to Section 5.2(b) until January 1, 2003. If
                  the Participant had transferred $25,000 from the Company Stock
                  Fund into the other Investment Funds, then the transferred
                  amount, as adjusted for subsequent earnings or losses, would
                  be distributable in cash in the form of a lump sum pursuant to
                  Section 5.2(a) until January 1, 2003. Only amounts actually
                  invested in the Company Stock Fund, for the requisite one-year
                  period, however, shall be distributable in Company Stock.

8.       Section 5.6 is hereby amended and restated in its entirety to read as
         follows:

                  5.6 ACCELERATED WITHDRAWALS. A Participant who is a current
                  employee may elect to receive an accelerated withdrawal of the
                  entire portion of his accounts that is subject to accelerated
                  withdrawal pursuant to Section 5.6(a) by filing a written
                  election with the Benefits Department. Only one accelerated
                  withdrawal may be elected during any 12-month period.
                  Accelerated withdrawals of amounts allocated to the Company
                  Stock Fund may be limited as described in paragraph (a).
                  Participants who have terminated employment, regardless of
                  whether they have elected or begun receiving installment or
                  annuity payments pursuant to Section 5.2(b), may not elect to
                  receive an accelerated withdrawal.

                           (a) AMOUNT OF WITHDRAWAL. An accelerated withdrawal
                  pursuant to this Section 5.6 shall be limited to the lesser of
                  (1) 50% of the value of the Participant's accounts, including
                  any amounts invested in the Company Stock Fund, or (2) the
                  amount that may be charged against the Participant's accounts
                  pursuant to Section 5.6(d). For purposes of determining the
                  amount to be distributed, the Participant's accounts shall be
                  valued as of the effective date of the withdrawal and shall be
                  paid as soon as reasonably possible thereafter.

                           (b) FORFEITURE. A Participant who elects an
                  accelerated withdrawal pursuant to this Section 5.6 shall
                  forfeit an amount equal to 10% of the amount withdrawn as of
                  the day on which the accelerated withdrawal is distributed to
                  the Participant.

                           (c) SUSPENSION OF PARTICIPATION. Any Participant who
                  elects to receive an accelerated withdrawal pursuant to this
                  Section 5.6 shall be suspended from making Supplemental
                  Deferrals or receiving Supplemental Matching or Employer
                  Credits for 12 months from the date that the accelerated
                  withdrawal is paid to the Participant. Upon expiration of the
                  12-month suspension period, the Participant shall be permitted
                  to execute a new Supplemental Deferral Agreement pursuant to
                  Section 3.2(b) and to begin making Supplemental Deferrals as
                  of the first day of the first payroll period in any subsequent
                  Plan Year.

                           (d) ALLOCATION OF AMOUNT WITHDRAWN AND FORFEITURE.
                  The amount withdrawn and any forfeiture will be charged to the
                  Participant's accounts in accordance with such procedures as
                  may be adopted from time to time by the Plan Administrator.
                  Withdrawals from the Company Stock Fund, however, shall be
                  subject to such procedures as the Company's General Counsel
                  (or his delegate) may prescribe from time to time to assure
                  compliance with Rule 16b-3 promulgated under Section 16(b) of
                  the Securities Exchange Act of 1934, as amended, and other
                  applicable securities law requirements. If the Participant is
                  unable, pursuant to the preceding sentence, to withdraw
                  amounts invested in the Company Stock Fund, then (1) no
                  portion of the withdrawal or forfeiture will be charged
                  against the amount allocated to the Company Stock Fund, and
                  (2) the withdrawal and forfeiture shall be limited to the
                  amount of the Participant's accounts that are invested in
                  Investment Funds other than the Company Stock Fund.

9.       This First Amendment shall only amend the provisions of the Plan
         referred to above, and those provisions not amended hereby shall be
         considered in full force and effect.

IN WITNESS WHEREOF, Public Service Company of New Mexico has caused this First
Amendment to be effective as of the day and year first above written.
