VINTELA, INC.

2003 STOCK OPTION PLAN

(as Amended on June 18, 2004)

ARTICLE 1

GENERAL PROVISIONS

I. PURPOSE OF THE PLAN

This 2003 Stock Option Plan is intended to promote the interests of Vintela, Inc., a Utah corporation, by providing eligible persons with the opportunity to acquire a proprietary interest, or otherwise increase their proprietary interest, in the Corporation as an incentive for them to remain in the service of the Corporation.

Capitalized terms herein shall have the meanings assigned to such terms in the attached Appendix.

II. ADMINISTRATION OF THE PLAN

A. The Plan shall be administered by the Board. However, any or all administrative functions otherwise exercisable by the Board may be delegated to the Committee. Members of the Committee shall serve for such period of time as the Board may determine and shall be subject to removal by the Board at any time. The Board may also at any time terminate the functions of the Committee and reassume all powers and authority previously delegated to the Committee.

B. The Plan Administrator shall have full power and authority (subject to the provisions of the Plan) to establish such rules and regulations as it may deem appropriate for proper administration of the Plan and to make such determinations under, and issue such interpretations of, the Plan and any outstanding options thereunder as it may deem necessary or advisable. Decisions of the Plan Administrator shall be final and binding on all parties who have an interest in the Plan or any option thereunder.

III. ELIGIBILITY

A. The persons eligible to participate in the Plan are as follows:

(i) Employees,

(ii) non-employee members of the Board or the non-employee members of the board of directors of any Parent or Subsidiary, and

(iii) consultants who provide services to the Corporation (or any Parent or Subsidiary).

B. The Plan Administrator shall have full authority to determine which eligible persons are to receive option grants, the time or times when such option grants are to be made, the number of shares to be covered by each such grant, the exercise price of option, the time or times at which each option is to become exercisable, the vesting schedule applicable to the option shares and the maximum term for which the option is to remain.

IV. STOCK SUBJECT TO THE PLAN

A. The stock issuable under the Plan shall be shares of authorized but unissued or re-acquired Common Stock. The maximum number of shares of Common Stock which may be issued over the term of the Plan shall not exceed 11,192,380 shares.*

B. Shares of Common Stock subject to outstanding options shall be available for subsequent issuance under the Plan to the extent (i) the options expire or terminate for any reason prior to exercise in full or (ii) the options are canceled in accordance with the cancellation-regrant provisions of Article 2. All shares issued under the Plan, whether or not those shares are subsequently repurchased by the Corporation pursuant to its repurchase rights under the Plan, shall reduce on a share-for-share basis the number of shares of Common Stock available for subsequent issuance under the Plan.

C. Should any change be made to the Common Stock by reason of any stock split, stock dividend, recapitalization, combination of shares, exchange of shares or other change affecting the outstanding Common Stock as a class without the Corporation’s receipt of consideration, appropriate adjustments shall be made to (i) the maximum number and/or class of securities issuable under the Plan and (ii) the number and/or class of securities and the exercise price per share in effect under each outstanding option in order to prevent the dilution or enlargement of benefits thereunder. The adjustments determined by the Plan Administrator shall be final, binding and conclusive.

C. Effect of Termination of Service. The following provisions shall govern the exercise of any options held by the Optionee at the time of cessation of Service or death:

D. Shareholder Rights. The holder of an option shall have no shareholder rights with respect to the shares subject to the option until such person shall have exercised the option, paid the exercise price and become a holder of record of the purchased shares.

E. Unvested Shares. The Plan Administrator shall have the discretion to grant options which are exercisable for unvested shares of Common Stock. Should the Optionee cease Service while holding such unvested shares, the Corporation shall have the right to repurchase, at the exercise price paid per share, all or (at the discretion of the Corporation and with the consent of the Optionee) any of those unvested shares.

Such right of first refusal shall be exercisable in accordance with the terms established by the Plan Administrator and set forth in the document evidencing such right.

G. Limited Transferability of Options. During the lifetime of the Optionee, the option shall be exercisable only by the Optionee and shall not be assignable or transferable other than by will, by the laws of descent and distribution following the Optionee’s death, or be assigned in accordance with the terms of a Qualified Domestic Relations Order. The assigned option may only be exercised by the person or persons who acquire a proprietary interest in the option pursuant to such Qualified Domestic Relations Order. The terms applicable to the assigned option (or portion thereof) shall be the same as those in effect for the option immediately prior to such assignment and shall be set forth in such documents issued to the assignee as the Plan Administrator may deem appropriate.

II. CORPORATE TRANSACTION

A. In the event of any Corporate Transaction, each outstanding option shall terminate and cease to be outstanding, except to the extent such option is assumed by the successor corporation (or parent thereof) in connection with such Corporate Transaction. In addition, all outstanding repurchase rights shall terminate automatically in the event of any Corporate Transaction, except to the extent the repurchase rights are assigned to the successor corporation (or parent thereof) in connection with such Corporate Transaction.

B. Each option which is assumed in connection with a Corporate Transaction shall be appropriately adjusted, immediately after such Corporate Transaction, to apply to the number and class of securities which would have been issuable to the Optionee in the

4

consummation of such Corporate Transaction, had the option been exercised immediately prior to such Corporate Transaction. Appropriate adjustments shall also be made to (i) the number and class of securities available for issuance under the Plan following the consummation of such Corporate Transaction and (ii) the exercise price payable per share under each outstanding option, provided the aggregate exercise price payable for such securities shall remain the same.

C. The grant of options under the Plan shall in no way affect the right of the Corporation to adjust, reclassify, reorganize or otherwise change its capital or business structure or to merge, consolidate, dissolve, liquidate or sell or transfer all or any part of its business or assets.

III. CANCELLATION AND REGRANT OF OPTIONS

The Plan Administrator shall have the authority to effect, at any time and from time to time, with the consent of the affected option holders, the cancellation of any or all outstanding options under the Plan and to grant in substitution therefor new options covering the same or different number of shares of Common Stock but with an exercise price per share based on the Fair Market Value per share of Common Stock on the new option grant date.

IV. ADDITIONAL AUTHORITY

The Plan Administrator shall have the discretion, exercisable either at the time an option is granted or at any time while the option remains outstanding, to:

(i) extend the period of time for which the option is to remain exercisable following the Optionee’s cessation of Service or death from the limited period otherwise in effect for that option to such greater period of time as the Plan Administrator shall deem appropriate, but in no event beyond the expiration of the option term;

(ii) permit the option to be exercised, during the applicable post-Service exercise period, not only with respect to the number of vested shares of Common Stock for which such option is exercisable at the time of the Optionee’s cessation of Service or death but also with respect to one or more additional installments in which the Optionee would have vested under the option had the Optionee continued in Service; and/or

(iii) accelerate or waive the Vesting Schedule and/or the date the option first becomes exercisable.
