EX-4.9



 Exhibit 4.9 
 English Language Summary of the Retention Plan-Stock Option Plan 
 Subscription of
Shares: Each executive may subscribe to the maximum number of shares granted under the plan, or to a portion thereof. The shares may be subscribed between the time when the company files its audited financial statements for the year 2012, and
April 22th, 2013. 
 Further, if the shares are not subscribed by April 22th 2013, the option is deemed waived and expires. 

Notice: The executive shall indicate his/her intent to exercise the option within 5 days of the exercise deadline. Such notice must also indicate
the number of shares for which the option will be exercised. 
 Payment of the Shares: The subscription of the Shares should be paid in cash,
promissory note and/or wire-transfer at the time of subscription. 
 Sales of subscribed shares: If the executive would like to sell the
shares granted under the plan, he/she will be limited, as follows: 
  

	 	1)	Up to 66% of acquired shares after the company files its audited financial statements for the year 2012. 


 

	 	2)	Up to 83% of acquired shares after the company files its audited financial statements for the year 2013. 


 

	 	3)	Up to 100% of the acquired shares after the company files its audited financial statements for the year 2014. 


As a condition of selling the shares, the executive must be an employee of the company or any of its affiliates at the time of each of the sales, and
his/her employment must be continuous since the date the option plan is granted until the date of the selling of the shares. 
 The shares must
be sold on the Santiago Stock Exchange and the sale price shall not be less than market value. The company in no way guarantees the share price at the time of sale by the executive. 
 Fine for noncompliance: The executive is subject to fine if any of the following are applicable at the time the executive sells his/her shares: 

 

	 	1)	The executive has not complied with the requirement to remain employed by the company or any of its affiliates. 


 

	 	2)	It is determined that the executive has committed serious misconduct. 

  

	 	3)	The executive has not complied with the requirements set forth above under “Sales of subscribed shares.” 


The fine is equal to the sales price of the shares, less the cost of acquiring the shares. The sales price is measured by the price of the shares on the
Santiago Stock Exchange, as follows: 
  

	 	A)	With respect to (1) above, at the time the executive breaches the requirement to remain an employee of the company or any of its affiliates;


  

	 	B)	With respect to (2) above, at the time the executive committed the serious misconduct; and 


 

	 	C)	With respect to (3) above, over the period of time that the shares were sold in violation of the requirements set forth above under “Sales of subscribed
shares.” 

 To ensure compliance with the option agreement, the executive is expected to appoint a representative from the
Company to sell his/her shares and pay any resulting fines to the company on behalf of the executive. 
 Pledge agreement: At the time
the executive exercises the stock option, he/she will enter into a pledge agreement limiting the transfer of the shares (in accordance with the installment periods outlined above). The pledge agreement will be in effect until March 31, 2015.
The pledge agreement is a condition precedent to the obligations set forth in the option plan. 
 Expiration: The plan expires on the
earlier of a) the date the executive is no longer employed by the company or any of its affiliates; b) the date it is determined that the executive has committed a serious breach of his/her employment contract; and c) March 31, 2015.








 Taxes and expenses: The executive is responsible for all taxes and expenses related to the
subscription and sale of the shares. The executive is responsible for complying with all applicable tax regulations and the company is exempt from all such liability. 
 Termination and Transfer of Rights: The executive may only transfer his/her option rights in the event of his/her death, by means of a will or through intestacy. In the case of the former, the
executive’s heirs may immediately subscribe for and sell the shares granted under the plan. If the executive transfers his/her option rights in violation of these restrictions, the executive is subject to a fine, up to the market value of the
shares at the time of the violation. 
 Future Option Plans: Upon the expiration of the option plan, the company is not obligated to
provide an equivalent plan. 
 The plan also includes general provisions related to confidentiality, dispute resolution, notices, domicile and
counterparts.
