 ATC SOUTH AMERICA HOLDING CORP. 
  
 2004 STOCK OPTION PLAN 
  

	 	1.	PURPOSE 

  
 The purpose of this 2004 Stock Option Plan (the “Plan”) is to encourage directors, officers and employees of and consultants and other persons providing services to ATC South America Holding Corp. (the
“Company”) and its Affiliates (as hereinafter defined) to continue their association with the Company and its Affiliates, by providing opportunities for such persons to participate in the ownership of the Company and in its future growth
through the granting of stock options (the “Options”) which may be options designed to qualify as incentive stock options (within the meaning of Section 422 of the Internal Revenue Code of 1986, as amended (the “Code”) (an
“ISO”), or Options not intended to qualify for any special tax treatment under the Code (a “NQO”). The term “Affiliate” as used in the Plan means a corporation or other business organization which owns in the Company,
or in which the Company or any such corporation or other business entity owns, directly or indirectly through an unbroken chain of ownership, fifty percent (50%) or more of the total combined voting power of all classes of stock. 
  

	 	2.	ADMINISTRATION OF THE PLAN 

  
 The Plan shall be administered by a committee (the “Committee”) consisting of two or more members of the Company’s Board of Directors (the
“Board”). The Committee shall from time to time determine to whom options or other rights shall be granted under the Plan, whether options granted shall be ISOs or NQOs, the terms of the options or other rights, and the number of shares
that may be granted under options. The Committee shall report to the Board the names of individuals to whom stock or options or other rights are to be granted, the number of shares covered, and the terms and conditions of each grant. The
determinations described in this Section 2 may be made by the Committee or by the Board, as the Board shall direct in its sole and absolute discretion, and references in the Plan to the Committee shall be understood to refer to the Board in any such
case. 
  
 The Committee shall select one of its members as
Chairman and shall hold meetings at such times and places as it may determine. A majority of the Committee shall constitute a quorum, and acts of the Committee at which a quorum is present, or acts reduced to or approved in writing by all the
members of the Committee, shall be the valid acts of the Committee. The Committee shall have the authority to adopt, amend, and rescind such rules and regulations as, in its opinion, may be advisable in the administration of the Plan. All questions
of interpretation and application of such rules and regulations, of the Plan and of Options, shall be subject to the determination of the Committee, which shall be final and binding. The Plan shall be administered in such a manner as to permit those
Options granted hereunder and specially designated under Section 5 as ISOs to qualify as incentive stock options as described in Section 422 of the Code. 
  
 For so long as Section 16 of the Securities Exchange Act of 1934, as amended from time to time (the “Exchange Act”), is applicable to the
Company, each member of the Committee shall be a “non-employee director” or the equivalent within the meaning of Rule 16b-3 under the Exchange Act, and, for so long as Section 162(m) of the Code is applicable to the Company, an
“outside director” within the meaning of Section 162 of the Code and the regulations thereunder. If, however, the Committee is not comprised of two or more “outside directors,” then, although the Committee may still administer
the Plan, the Compensation Committee of the Board of Directors of American Tower Corporation (“ATC”), so long as it is the parent of the Company, or such other committee that makes grants pursuant to the parent’s stock option or
similar plan, shall make grants of options or other rights under the Plan (if the Compensation Committee or such committee consists of two or more members who are “outside directors”). 






Table of Contents


 With respect to persons subject to Section 16 of the Exchange Act (“Insiders”), transactions
under the Plan are intended to comply with all applicable conditions of Rule 16b-3 or its successor under the Exchange Act. To the extent any provision of the Plan or action by the Committee fails to so comply, it shall be deemed to be modified so
as to be in compliance with such Rule, or, if such modification is not possible, it shall be deemed to be null and void, to the extent permitted by law and deemed advisable by the Committee. 
  

	 	3.	OPTION SHARES 

  
 The stock subject to Options under the Plan shall be shares of Common Stock, par value $.01 per share (the “Stock”). The total amount of the
Stock with respect to which Options may be granted (the “Option Pool”), shall not exceed in the aggregate 6,144 shares; provided, however, such aggregate number of shares shall be subject to adjustment in accordance with the provisions of
Section 17. If an outstanding Option shall expire for any reason or shall terminate by reason of the death or severance of employment of the Optionee, the surrender of any such Option, or any other cause, the shares of Stock allocable to the
unexercised portion of such Option may again be subject to an option under the Plan. The maximum number of shares of Stock subject to Options that may be granted to any Optionee in the aggregate in any calendar year shall not exceed 3,925 shares,
subject to adjustment in accordance with the provisions of Section 17. 
  

	 	4.	AUTHORITY TO GRANT OPTIONS 

  
 The Committee may determine, from time to time, which employees of the Company or any Affiliate or other persons shall be granted Options under the Plan,
the terms of the Options (including without limitation whether an Option shall be an ISO or a NQO), and the number of shares which may be purchased under the Option or Options. Without limiting the generality of the foregoing, the Committee may from
time to time grant: (a) to such employees (other than employees of an Affiliate which is not a corporation) as it shall determine an Option or Options to buy a stated number of shares of Stock under the terms and conditions of the Plan which Option
or Options will to the extent so designated at the time of grant constitute an ISO; and (b) to such eligible directors, employees or other persons as it shall determine an Option or Options to buy a stated number of shares of Stock under the terms
and conditions of the Plan which Option or Options shall constitute a NQO. Subject only to any applicable limitations set forth elsewhere in the Plan, the number of shares of Stock to be covered by any Option shall be as determined by the Committee.

  

	 	5.	WRITTEN AGREEMENT 

  
 Each Option granted hereunder shall be embodied in an option agreement (the “Option Agreement”) substantially in the form of Exhibit 1, which
shall be signed by the Optionee and by a duly authorized officer of the Company for and in the name and on behalf of the Company. An Option Agreement may contain such restrictions on exercisability and such other provisions not inconsistent with the
Plan as the Committee in its sole and absolute discretion shall approve. 
  

	 	6.	ELIGIBILITY 

  
 The individuals who shall be eligible for grant of Options under the Plan shall be employees (including officers who may be members of the Board), directors who are not employees and other individuals, whether or not
employees, who render services of special importance to the management, operation or development of the Company or an Affiliate, and who have contributed or may be expected to contribute to the success of the Company or an Affiliate. An employee,
director or other person to whom an Option has been granted pursuant to an Option Agreement is hereinafter referred to as an “Optionee.”

	 	7.	OPTION PRICE 

  
 The price at which shares of Stock may be purchased pursuant to an Option shall be specified by the Committee at the time the Option is granted, but shall
in no event be less than the par value of such shares and, in the case of an ISO, except as set forth in the following sentence, one hundred percent (100%) of the fair market value of the Stock on the date the ISO is granted. In the case of an
employee who owns (or is considered under Section 424(d) of the Code as owning) stock possessing more than ten percent (10%) of the total combined voting power of all classes of stock of the Company or any Affiliate, the price at which shares of
Stock may be so purchased pursuant to an ISO shall be not less than one hundred and ten percent (110%) of the fair value of the Stock on the date the ISO is granted. 
  
 For purposes of the Plan, the “fair market value” of a share of Stock on any date specified herein, shall mean (a)
the last reported sales price, regular way, or, in the event that no sale takes place on such day, the average of the reported closing bid and asked prices, regular way, in either case (i) as reported on the New York Stock Exchange Composite Tape,
or (ii) if the Stock is not listed or admitted to trading on the New York Stock Exchange, on the principal national securities exchange on which such security is listed or admitted to trading, or (iii) if not then listed or admitted to trading on
any national securities exchange, on the NASDAQ National Market System; or (b) if the Stock is not quoted on such National Market System, (i) the average of the closing bid and asked prices on each such day in the over-the-counter market as reported
by NASDAQ, or (ii) if bid and asked prices for such security on each such day shall not have been reported through NASDAQ, the average of the bid and asked prices for such day as furnished by any New York Stock Exchange member firm regularly making
a market in such security selected for such purpose by the Committee; or (c) if the Stock is not then listed or admitted to trading on any national exchange or quoted in the over-the-counter market, the fair value thereof will be based on the
Company Value; provided, however, that any method of determining fair market value employed by the Committee with respect to an ISO shall be consistent with any applicable laws or regulations pertaining to “incentive stock options”.

  

	 	8.	DURATION OF OPTIONS 

  
 The duration of any Option shall be specified by the Committee in the Option Agreement, but no Option shall be exercisable after the expiration of ten
(10) years from the date such Option is granted. In the case of any employee who owns (or is considered under Section 424(d) of the Code as owning) stock possessing more than ten percent (10%) of the total combined voting power of all classes of
stock of the Company or any Affiliate, no ISO shall be exercisable after the expiration of five (5) years from the date such Option is granted. The Committee, in its sole and absolute discretion, may extend any Option theretofore granted.

  

	 	9.	VESTING PROVISIONS 

  
 Each Option may be exercised so long as it is valid and outstanding from time to time, in part or as a whole, in such manner and subject to such
conditions as the Committee, in its sole and absolute discretion, may provide in the Option Agreement. The Committee may, in its sole and absolute discretion, accelerate Options, in whole or in part, on such terms and conditions as the Committee
may, in its sole and absolute discretion, determine. 
  

	 	10.	EXERCISE OF OPTIONS 

  
 Options shall be exercised by the delivery of written notice to the Company setting forth the number of shares of Stock with respect to which the Option
is to be exercised, accompanied by payment 
  

 - 3 - 







Table of Contents


 of the option price of such shares, which payment shall be made, subject to the alternative provisions of this Section,
in cash or by such cash equivalents, payable to the order of the Company in an amount in United States dollars equal to the option price of such shares, as the Committee in its sole and absolute discretion shall consider acceptable. Such notice
shall be delivered in person to the Secretary of the Company or shall be sent by registered mail, return receipt requested, to the Secretary of the Company, in which case delivery shall be deemed made on the date such notice is deposited in the
mail. 
  
 Alternatively, if the Option Agreement so specifies, and
subject to such rules as may be established by the Committee, payment of the option price may be made through a so-called “cashless exercise” procedure, under which the Optionee shall deliver irrevocable instructions to a broker to sell
shares of Stock acquired upon exercise of the Option and to remit promptly to the Company a sufficient portion of the sale proceeds to pay the option price and any tax withholding resulting from such exercise. 
  
 Alternatively, payment of the option price may be made, in whole or in part,
in shares of Stock owned by the Optionee; provided, however, that the Optionee may not make payment in shares of Stock that he acquired upon the earlier exercise of any ISO (or other “incentive stock option”), unless and until he has held
the shares until at least two (2) years after the date the ISO (or such other incentive stock option) was granted and at least one (1) year after the date the ISO (or such other option) was exercised. If payment is made in whole or in part in shares
of Stock, then the Optionee shall deliver to the Company in payment of the option price of the shares with respect of which such Option is exercised (a) certificates registered in the name of such Optionee representing a number of shares of Stock
legally and beneficially owned by such Optionee, free of all liens, claims and encumbrances of every kind, and having a fair market value on the date of delivery of such notice equal to the option price of the shares of Stock with respect to which
such Option is to be exercised, such certificates to be accompanied by stock powers duly endorsed in blank by the record holder of the shares of Stock represented by such certificates; and (b) if the option price of the shares with respect to which
such Option is to be exercised exceeds such fair market value, cash or such cash equivalents payable to the order to the Company, in an amount in United States dollars equal to the amount of such excess, as the Committee in its sole and absolute
discretion shall consider acceptable. Notwithstanding the foregoing provisions of this Section, the Committee, in its sole and absolute discretion, (i) may refuse to accept shares of Stock in payment of the option price of the shares of Stock with
respect to which such Option is to be exercised and, in that event, any certificates representing shares of Stock which were delivered to the Company with such written notice shall be returned to such Optionee together with notice by the Company to
such Optionee of the refusal of the Committee to accept such shares of Stock and (ii) may accept, in lieu of actual delivery of stock certificates, an attestation by the Optionee substantially in the form attached herewith as Exhibit B or such other
form as may be deemed acceptable by the Committee that he or she owns of record the shares to be tendered free and clear of all liens, claims and encumbrances of every kind. 
  
 As promptly as practicable after the receipt by the Company of (a) written notice from the Optionee setting forth the number
of shares of Stock with respect to which such Option is to be exercised and (b) payment of the option price of such shares in the form required by the foregoing provisions of this Section, the Company shall cause to be delivered to such Optionee
certificates representing the number of shares with respect to which such Option has been so exercised (less a number of shares equal to the number of shares as to which ownership was attested under the procedure described in clause (ii) of the
preceding paragraph). 
  

	 	11.	TRANSFERABILITY OF OPTIONS 

  
 Options shall not be transferable by the Optionee otherwise than by will or under the laws of descent and distribution, and shall be exercisable during
his or her lifetime only by the Optionee, except that the Committee may, subject to such conditions as it shall, in its sole and absolute discretion, determine, specify in an Option Agreement that pertains to an NQO that the Optionee may transfer
such NQO to a member of the Immediate Family of the Optionee, to a trust solely for the benefit of the 
  

 - 4 - 







Table of Contents


 Optionee and the Optionee’s Immediate Family, or to a partnership or limited liability company whose only partners
or members are the Optionee and members of the Optionee’s Immediate Family. “Immediate Family” shall mean, with respect to any Optionee, such Optionee’s child, stepchild, grandchild, parent, stepparent, grandparent, spouse,
sibling, mother-in-law, father-in-law, son-in-law, daughter-in-law, brother-in-law, or sister-in-law, and shall include adoptive relationships. 
  

	 	12.	TERMINATION OF EMPLOYMENT OR INVOLVEMENT OF OPTIONEE WITH THE COMPANY 

  
 For purposes of this Section, employment by or involvement with (in the case of an Optionee who is not an employee) an Affiliate shall be considered
employment by or involvement with the Company. Except as otherwise set forth in the Option Agreement, after the Optionee’s termination of employment with the Company other than by reason of death or disability, including his retirement in good
standing from the employ of the Company for reasons of age under the then established rules of the Company, the Option shall terminate on the earlier of the date of its expiration or three (3) months after the date of such termination or retirement.
After the death of the Optionee, his or her executors, administrators or any persons to whom his or her Option may be transferred by will or by the laws of descent and distribution shall have the right to exercise the Option to the extent to which
the Optionee was entitled to exercise the Option. The Committee may, subject to such conditions as it shall, in its sole and absolute discretion, determine, specify in an Option Agreement that, in the event that such termination is a result of
disability, the Optionee shall have the right to exercise the Option pursuant to its terms as if such Optionee continued as an employee. 
  
 Authorized leave of absence or absence on military or government service shall not constitute severance of the employment relationship between the Company
and the Optionee for purposes of the Plan, provided that either (a) such absence is for a period of no more than ninety (90) days or (b) the Employee’s right to re-employment after such absence is guaranteed either by law or by contract.

  
 For Optionees who are not employees of the Company, options
shall be exercisable for such periods following the termination of the Optionee’s involvement with the Company as may be set forth in the Option Agreement. 
  


	 	13.	REQUIREMENTS OF LAW 

  
 The Company shall not be required to sell or issue any shares of Stock upon the exercise of any Option if the issuance of such shares shall constitute or
result in a violation by the Optionee or the Company of any provisions of any law, statute or regulation of any governmental authority. Specifically, in connection with the Securities Act of 1933, as amended (the “Securities Act”), and any
applicable state securities or “blue sky” law (a “Blue Sky Law”), upon exercise of any Option the Company shall not be required to issue such shares unless the Committee has received evidence satisfactory to it to the effect that
the holder of such Option will not transfer such shares except pursuant to a registration statement in effect under the Securities Act and Blue Sky Laws or unless an opinion of counsel satisfactory to the Company has been received by the Company to
the effect that such registration and compliance is not required. Any determination in this connection by the Committee shall be final, binding and conclusive. The Company shall not be obligated to take any action in order to cause the exercise of
an Option or the issuance of shares of Stock pursuant thereto to comply with any law or regulations of any governmental authority, including, without limitation, the Securities Act or applicable Blue Sky Law. 
  
 Notwithstanding any other provision of the Plan to the contrary, the Company
may refuse to permit transfer of shares of Stock if in the opinion of its legal counsel such transfer would violate federal or state securities laws or subject the Company to liability thereunder. Any sale, assignment, transfer, pledge or other
disposition of shares of Stock received upon exercise of any Option (or any other shares or securities derived therefrom) which is not in accordance with the provisions of this Section shall be void and of no effect and shall not be recognized by
the Company.

 Legend on Certificates. The Committee may cause any certificate representing shares of Stock
acquired upon exercise of an Option (and any other shares or securities derived therefrom) to bear a legend to the effect that the securities represented by such certificate have not been registered under the Securities Act of 1933, as amended, or
any applicable state securities laws, and may not be sold, assigned, transferred, pledged or otherwise disposed of except in accordance with the Plan and applicable agreements binding the holder and the Company or any of its stockholders.

  

	 	14.	NO RIGHTS AS STOCKHOLDER 

  
 No Optionee shall have any rights as a stockholder with respect to shares covered by his or her Option until the date of issuance of a stock certificate
for such shares; except as otherwise provided in Section 17, no adjustment for dividends or otherwise shall be made if the record date therefor is prior to the date of issuance of such certificate. 
  

	 	15.	EMPLOYMENT OBLIGATION 

  
 The granting of any Option shall not impose upon the Company or any Affiliate any obligation to employ or continue to employ any Optionee, or to engage or
retain the services of any person, and the right of the Company or any Affiliate to terminate the employment or services of any person shall not be diminished or affected by reason of the fact that an Option has been granted to him or her. The
existence of any Option shall not be taken into account in determining any damages relating to termination of employment or services for any reason. 
  
 16. CERTAIN RIGHTS OF THE COMPANY 
  
 (a) Voluntary or Involuntary Transfers of Stock. The voluntary or involuntary transfer of shares of Stock acquired by an Optionee pursuant to the
exercise of an Option or Options granted under the Plan is subject to the provisions of the Stockholder Agreement. 
  
 (b) Termination of Employment or Involvement. If the Optionee’s employment by or involvement with the Company (including, for this purpose,
any Affiliate) shall terminate because of (x) the death or Disability of Optionee, (y) a Wrongful Termination, or (z) a Forfeiture Event, the Company shall have the assignable right to repurchase all but not less than all of the shares of Stock (or
other shares or securities derived therefrom) acquired pursuant to the exercise of an Option at a price equal to the Put/Call Price at the time of such repurchase. In addition, if at the time of such termination an Optionee holds an Option granted
under the Plan which is by its terms exercisable after such termination, the Company shall have the assignable right to repurchase all but not less than all of the shares of Stock acquired pursuant to the exercise of such Option, at the Put/Call
Price at the time of such repurchase. If the option price for any repurchased shares has been paid by the Optionee’s promissory note pursuant to Section 10, then the repurchase price for such shares of Stock shall be first applied to the
repayment of the outstanding amount, if any, due under such note in respect of the repurchased shares, and any accrued but unpaid interest thereon. The Company’s right to repurchase shares of Stock (or other shares or securities) may be
exercised at any time not earlier than one hundred and eighty (180) days following the exercise of the Option with respect to the shares of Stock (or other shares or securities) to be repurchased, and not later than three hundred and sixty-five
(365) days following the date of (i) the Optionee’s termination of employment or involvement or (ii) in the case of a repurchase of shares of Stock (or other shares or securities) acquired pursuant to the exercise of an Option subsequent to
such termination, such exercise. Any such shares of Stock (or other shares or securities) as to which the Company does not exercise its repurchase rights within such period shall thereafter be free of the foregoing restrictions, but subject,
however, to the provisions of the Stockholder Agreement.

	 	17.	CHANGES IN THE COMPANY’S CAPITAL STRUCTURE 

  
 The existence of outstanding Options shall not affect in any way the right or power of the Company or its stockholders to make or authorize any or all
adjustments, recapitalizations, reorganizations or other changes in the Company’s capital structure or its business or any merger or consolidation of the Company or any issue of bonds, debentures, preferred or preference stock, whether or not
convertible into the Stock or other securities, ranking prior to the Stock or affecting the rights thereof, or warrants, rights or options to acquire the same, or the dissolution or liquidation of the Company or any sale or transfer of all or any
part of its assets or business or any other corporate act or proceeding, whether of a similar character or otherwise. 
  
 The number of shares of Stock in the Option Pool (less the number of shares theretofore delivered upon exercise of Options) and the number of shares of
Stock covered by any outstanding Option and the price per share payable upon exercise thereof (provided that in no event shall the option price be less than the par value of such shares) shall be proportionately adjusted for any increase or decrease
in the number of issued and outstanding shares of Stock resulting from any subdivision, split, combination or consolidation of shares of Stock or the payment of a dividend on the Stock in shares of Stock or other securities of the Company. The
decision of the Board as to the adjustment, if any, required by the provisions of this Section shall be final, binding and conclusive. 
  
 If the Company merges or consolidates with a wholly-owned subsidiary for the purpose of reincorporating itself under the laws of another jurisdiction, the
Optionees will be entitled to acquire shares of Stock of the reincorporated Company upon the same terms and conditions as were in effect immediately prior to such reincorporation (unless such reincorporation involves a change in the number of shares
or the capitalization of the Company, in which case proportional adjustments shall be made as provided above) and the Plan, unless otherwise rescinded by the Board, will remain the Plan of the reincorporated Company. 
  
 Except as otherwise provided in the preceding paragraph, if the Company is
merged or consolidated with another corporation, whether or not the Company is the surviving entity, or if the Company is liquidated or sells or otherwise disposes of all or substantially all of its assets to another entity while unexercised Options
remain outstanding under the Plan, or if other circumstances occur in which the Board in its sole and absolute discretion deems it appropriate for the provisions of this paragraph to apply (in each case, an “Applicable Event”), then (a)
each holder of an outstanding Option shall be entitled, upon exercise of such Option, to receive in lieu of shares of Stock, such stock or other securities or property as he or she would have received had he exercised such option immediately prior
to the Applicable Event; (b) the Board may, in its sole and absolute discretion, waive, generally or in one or more specific cases, any limitations imposed pursuant to Section 9 so that some or all Options from and after a date prior to the
effective date of such Applicable Event, specified by the Board, in its sole and absolute discretion, shall be exercisable in full or in part; (c) the Board may, in its sole and absolute discretion, cancel all outstanding and unexercised Options as
of the effective date of any such Applicable Event; (d) the Board may, in its sole discretion, convert some or all Options into options to purchase the stock or other securities of the surviving corporation pursuant to an Applicable Event; or (e)
the Board may, in its sole and absolute discretion, assume the outstanding and unexercised options to purchase stock or other securities of any corporation and convert such options into Options to purchase Stock, whether pursuant to this Plan or
not, pursuant to an Applicable Event; provided, however, in the case of any such cancellation pursuant to clause (c), (i) notice shall be given to each holder of an Option not less than thirty (30) days preceding the effective date of such
Applicable Event, and (ii) all such outstanding and unexercised Options shall immediately vest, to the extent that were not so vested so that such Options shall be exercisable in full during such thirty (30) day period. 
  
 Except as expressly provided herein, the issue by the Company of shares of
Stock or other securities of any class or series or securities convertible into or exchangeable or exercisable for shares of 
  

 - 7 - 







Table of Contents


 Stock or other securities of any class or series for cash or property or for labor or services either upon direct sale or
upon the exercise of rights or warrants to subscribe therefor, or upon conversion of shares or obligations of the Company convertible into such shares or other securities, shall not affect, and no adjustment by reason thereof shall be made with
respect to, the number, class or price of shares of Stock then subject to outstanding Options. 
  

	 	18.	AMENDMENT OR TERMINATION OF PLAN 

  
 The Board may, in its sole and absolute discretion, modify, revise or terminate the Plan at any time and from time to time; provided, however, that
without the further approval of the holders of at least a majority of the outstanding shares of Stock, the Board may not change the aggregate number of shares of Stock which may be issued under Options pursuant to the provisions of the Plan either
to any one person or in the aggregate; or change the class of persons eligible to receive ISOs. Notwithstanding the preceding sentence, the Board shall in all events have the power and authority to make such changes in the Plan and in the
regulations and administrative provisions hereunder or in any outstanding Option as, in the opinion of counsel for the Company, may be necessary or appropriate from time to time to enable any Option granted pursuant to the Plan to qualify as an ISO
or such other stock option as may be defined under the Code, as amended from time to time, so as to receive preferential federal income tax treatment. 
  

	 	19.	CERTAIN TERMS

 (a) any
willful or gross failure or refusal to perform, or any willful or gross misconduct in the performance of, any significant portion of his obligations, duties and responsibilities as an officer or employee of the Company, the effect of which has been

 ATC SOUTH AMERICA HOLDING CORP. 2004 STOCK OPTION PLAN 
  
 OPTION AGREEMENT 
  
 OTHER TERMS OF THE OPTION 
  
 WHEREAS, the Board of Directors (the “Board”) has authorized the
grant of stock options upon certain terms and conditions set forth in the Plan and herein; and 
  
 WHEREAS, the Committee (as defined in the Plan) has authorized the grant of this stock option pursuant and subject to the terms of the Plan, a copy of which is available from the Company and is hereby incorporated
herein; 
  
 NOW, THEREFORE, in consideration of the premises and
the mutual covenants and agreements herein contained, the Company and the Optionee, intending to be legally bound, covenant and agree as set forth on the first page hereof and as follows: 
  
 7. Grant. Pursuant and subject to the Plan, the Company does hereby
grant to the Optionee a stock option (the “Option”) to purchase from the Company the number of shares of Stock set forth in Section 3 on the first page hereof upon the terms and conditions set forth in the Plan and upon the additional
terms and conditions contained herein. If so provided in Section 4 on the first page hereof, this Option is an incentive stock option and is intended to qualify for special federal income tax treatment as an “incentive stock option”
pursuant to Section 422 of the Code. 
  
 8. Option Price.
This Option may be exercised at the option price per share of Stock set forth in Section 4 on the first page hereof, subject to adjustment as provided herein and in the Plan. 
  
 9. Term and Exercisability of Option. This Option shall expire on the date determined pursuant to Section 5 on first
page hereof and shall be exercisable prior to that date in accordance with and subject to the conditions set forth in this Section 9 and the Plan. This Option shall become exercisable in its entirety upon the soonest to occur of (a) the exercise by
or on behalf of J. Michael Gearon, Jr. of his rights set forth in Section 6(a) of the Stockholder Agreement, (b) the exercise by ATC of its rights pursuant to the provisions of Section 6(b)(i) of the Stockholder Agreement, or (c) a Change of
Control. 
  
 If before this Option has been exercised in full the
Optionee ceases to be an employee of or ceases to provide services for the Company or an Affiliate for any reason other than a termination for a reason specified in Section 16 of the Plan, the Optionee may exercise this Option to the extent that he
or she might have exercised it on the date of termination of his or her employment (or provision of services), but only during the period ending on the earlier of (a) the date on which the Option expires in accordance with Section 5 of the first
page hereof or (b) three (3) months after the date of termination of the Optionee’s employment with or provision of services for the Company or an Affiliate. However, if the Optionee dies before the date of expiration of this Option and while
in the employ of or during the course of providing services for the Company or an Affiliate, or during the three month period described in the preceding sentence, or in the event of the retirement of the Optionee for reasons of disability (within
the meaning of Code §22(e)(3)), the Option shall remain exercisable until its expiration in accordance with Section 5 on the first page hereof or, in the case of an Option designated as an incentive stock option, the earlier of one year from
the date of such death or retirement or the date of its expiration. If the Optionee dies before this Option has been exercised in full, the executor, administrator or personal representative of the estate of the Optionee may exercise this Option as

 10. Method of Exercise. To the extent that the right to purchase shares of Stock has accrued
hereunder, this Option may be exercised from time to time by written notice to the Company substantially in the form attached hereto as Exhibit A, stating the number of shares with respect to which this Option is being exercised, and accompanied by
payment in full of the option price for the number of shares to be delivered, by means of payment acceptable to the Company in accordance with Section 10 of the Plan. As soon as practicable after its receipt of such notice, the Company shall,
without transfer or issue tax to the Optionee (or other person entitled to exercise this Option), deliver to the Optionee (or other person entitled to exercise this Option), at the principal executive offices of the Company or such other place as
shall be mutually acceptable, a certificate or certificates for such shares out of theretofore authorized but unissued shares or reacquired shares of its Stock as the Company may elect; provided, however, that the time of such delivery may be
postponed by the Company for such period as may be required for it with reasonable diligence to comply with any applicable requirements of law. Payment of the option price may be made in cash or cash equivalents or, in accordance with the terms and
conditions of Section 10 of the Plan in whole or in part in shares of Common Stock of the Company, whether or not through the attestation procedure in the Plan; provided, however, that the Board reserves the right upon receipt of any written notice
of exercise from the Optionee to require payment in cash with respect to the shares contemplated in such notice if the receipt of the shares of Common Stock would result in a compensation expense to the Company or any Affiliate of the Company for
financial reporting purposes. If the Optionee (or other person entitled to exercise this Option) fails to pay for and accept delivery of all of the shares specified in such notice upon tender of delivery thereof, the right to exercise this Option
with respect to such shares not paid for may be terminated by the Company. 
  
 11. Nonassignability of Option Rights. This Option shall not be assignable or transferable by the Optionee except by will or by the laws of descent and distribution and shall be exercisable during the life of
the Optionee only by the Optionee; provided, however, that the Option may transfer this Option with the consent of the Committee to a person or entity identified in Section 11 of the Plan. 
  
 12. Compliance with Securities Act. The Company shall not be obligated
to sell or issue any shares of Stock or other securities pursuant to the exercise of this Option unless the shares of Stock or other securities with respect to which this Option is being exercised are at that time effectively registered or exempt
from registration under the Securities Act of 1933, as amended, and applicable state securities laws. In the event shares or other securities shall be issued which shall not be so registered, the Optionee hereby represents, warrants and agrees that
the shares or other securities received will be held for investment and not with a view to their resale or distribution, and he or she will execute an appropriate investment letter satisfactory to the Company and its counsel. 
  
 13. Legends. The Optionee hereby acknowledges that the stock
certificate or certificates evidencing shares of Stock or other securities issued pursuant to any exercise of this Option will bear a legend setting forth the restrictions on their transferability described in Section 12 hereof and to the
restrictions on transfer set forth in the Stockholder Agreement. 
  
 14. Rights as Stockholder. The Optionee shall have no rights as a stockholder with respect to any shares of Stock or other securities covered by this Option until the date of issuance of a certificate to him or her for such shares or
other securities. No adjustment shall be made for dividends or other rights for which the record date is prior to the date such stock certificate is issued. 
  
 15. Withholding Taxes. The Optionee hereby agrees, as a condition to any exercise of this Option, to provide to the Company an amount sufficient to
satisfy its obligation to withhold federal, state, local, Mexican and other applicable taxes arising by reason of such exercise (the “Withholding Amount”) by (a) authorizing the Company to withhold the Withholding Amount from his or her
cash compensation, 
  

 - 3 - 







Table of Contents


 or (b) remitting the Withholding Amount to the Company in cash; provided, however, that to the extent that the
Withholding Amount is not provided by one or a combination of such methods, the Company in its sole and absolute discretion may refuse to issue such shares of Stock or may withhold from the shares of Stock delivered upon exercise of this Option that
number of shares having a Fair Market Value, on the date of exercise, sufficient to eliminate any deficiency in the Withholding Amount; and provided, further, that the Fair Market Value of shares withheld shall not exceed an amount in excess of the
minimum required withholding. 
  
 16. Notice of Disqualifying
Disposition. If this Option is an incentive stock option, the Optionee agrees to notify the Company promptly in the event that he sells, transfers, exchanges or otherwise disposes of any shares of Stock issued upon exercise of the Option, before
the later of (a) the second anniversary of the date of grant of the Option and (b) the first anniversary of the date the shares were issues upon his exercise of the Option. 
  
 17. Termination or Amendment of Plan. The Board may in its sole and absolute discretion at any time terminate or from
time to time modify and amend the Plan, but no such termination or amendment will affect rights and obligations under this Option. 
  
 18. Effect Upon Employment. Nothing in this Option or the Plan shall be construed to impose any obligation upon the Company to employ or retain in
its employ, or continue its involvement with, the Optionee. 
  
 19. Time for Acceptance. Unless the Optionee shall evidence acceptance of this Option by executing the Notice of Grant of Stock Options, which forms a part of this Agreement, and returning it to the Company within thirty (30) days
after its delivery, the Option and this Agreement shall be voidable by the Company in its sole and absolute discretion. 
  
 20. General Provisions. 
  
 (a) Amendment; Waivers. This Agreement, including the Plan, contains the full and complete understanding and agreement of the
parties hereto as to the subject matter hereof and, except as otherwise permitted by the express terms of the Plan and this Agreement, it may not be modified or amended, nor may any provision hereof be waived, except by a further written agreement
duly signed by each of the parties; provided, however, that a modification or amendment that does not materially diminish the rights of the Optionee hereunder, as they may exist immediately before the effective date of the modification or amendment,
shall be effective upon notice of its provisions to the Optionee. The waiver by either of the parties hereto of any provision hereof in any instance shall not operate as a waiver of any other provision hereof or in any other instance. 
  
 (b) Binding Effect. This Agreement shall inure to the
benefit of and be binding upon the parties hereto and, to the extent provided herein and in the Plan, their respective heirs, executors, administrators, representatives, successors and assigns. 
  
 (c) Construction. This Agreement is to be construed in
accordance with the terms of the Plan. In case of any conflict between the Plan and this Agreement, the Plan shall control. The titles of the sections of this Agreement and of the Plan are included for convenience only and shall not be construed as
modifying or affecting their provisions. The masculine gender shall include both sexes; the singular shall include the plural and the plural the singular unless the context otherwise requires. Capitalized terms not defined herein shall have the
meanings given to them in the Plan
