(b) Special Dilution Provision

(i) In the event the Company proposes to issue additional shares of capital stock, the Company shall deliver to each Shareholder a written notice (an “Issuance Notice”) of such proposed Issuance at least forty (40) Business Days prior to the date of the proposed issuance (the “Subscription Period”).

If that is the case, in preparing the equity valuation, the selected investment bank shall consider in the context of a non-public company seeking to raise equity (i) at least the following methods of valuation: discounted cash flows;

comparable transactions; and trading prices of shares of comparable publicly-held companies (applying such methods consistently with the application of such valuation methods and standards in the personal communications networks industry) and (ii) the indebtedness of the Company. The Company shall cooperate in good faith with the investment bank, and provide all the documentation and information requested to perform the equity valuation. Upon receipt of the documentation and information necessary to complete the equity valuation, the investment bank shall present a report including its equity valuation within fifteen (15) Business Days of its selection by TEMPR, including, among other things, a fairness opinion as to the proposed subscription price addressed to TEMPR, as of the date of the equity valuation.

(iii) Upon the earlier to occur of (a) the receipt of the external equity valuation, or (b) the receipt of the Option Notice whereby TEMPR notifies that it will not request the external equity valuation, the Company shall deliver written notification (the “Valuation Notification”) to each Shareholder of the issuance price, and a copy of the external equity valuation, as applicable, and the proposed date of Issuance, which shall be no less than ten (10) and no more than forty (40) Business Days after the delivery of the Valuation Notification to each Shareholder. Each Shareholder shall have the option, exercisable at any time during the Subscription Period by delivering written notice to the Company (a “Subscription Acceptance”) to subscribe for up to its Proportionate Share of any such additional Shares (a “Preemptive Right”), at the same price per security and upon same terms as those of the proposed Issuance of such additional Shares. The “Proportionate Share” of each Shareholder shall be equal to a fraction, the numerator of which is the number of outstanding shares owned by such Party, on a fully diluted basis, and the denominator of which is the aggregate number of Shares outstanding on a fully diluted basis.

(iv) In the event the external equity valuation is equal to or higher than 85% of the subscription price set forth in the Issuance Notice or TEMPR does not request an external equity valuation, if TEMPR (i) waives its Preemptive Right attached to its Original Shares prior to the expiration of the Subscription Period by giving prior written notice to the Company, or (ii) fails to deliver its Subscription Acceptance within the Subscription Period, TEMPR shall be obligated to transfer, at no cost, to the Other Shareholders the number of its Original Shares needed for the Original Shares held by the Other Shareholders not to be diluted because of the issuance.

(v) In the event the external equity valuation is equal to or higher than 85% of the subscription price set forth in the Issuance Notice or TEMPR does not request an external equity valuation, if TEMPR elects to partially, but not fully subscribe its Proportional Share as regards its Original Shares, TEMPR shall be obligated to transfer, at no cost, to the Other Shareholders the number of its Original Shares needed for the Original Shares held by the Other Shareholders not to be diluted because of the issuance with respect only to the part of the Proportional Share not subscribed by TEMPR.

(vi) The aggregate number of Shares to be transferred by TEMPR to the Other Shareholders pursuant to Section 6.1(b)(iv) or (v), as applicable, (i) shall, under no circumstance, (y) exceed the aggregate number of Original Shares owned by TEMPR immediately prior to the Issuance Notice, (z) be affected by the exercise, if any, by the Other Shareholders of their respective Preemptive Rights pursuant to Section 6.1(b)(i), and (ii) shall be allocated among such Other Shareholders proportionately based upon the relative number of Original Shares owned by such Other Shareholders immediately prior to the Issuance Notice. For avoidance of doubt, the transfer and dilution mechanisms set forth in Section 6.1(b)(iv) and (v), as applicable, shall only apply in the event (i) TEMPR (y) does not exercise its Preemptive Right or (z) elects to exercise its Preemptive Rights for less than the total number of shares it is entitled to acquire thereunder and (ii) the external equity valuation is not below 85% of the subscription price set forth in the Issuance Notice or there is no external equity valuation.

(vii) It is acknowledged and agreed that for so long as TEMPR is a shareholder of the Company, TEMPR may elect, at its sole and absolute discretion and option, to subscribe to any such issuance either by capital contribution, or by converting any FCC Related Debt (valued at principal plus accrued and unpaid interest) that it may hold as of the date of such issuance into shares at the subscription price.

(viii) This clause 6.1 (b) shall be applicable for such period of time as TEMPR may exercise its call rights (including any extension agreed by the Parties) under the Stock Purchase Agreement.

(b) The Notice of Transfer shall state that a Proposal has been received and shall contain all the terms and conditions of the Proposal and a copy of all supporting documents.

(c) (i) The Optionees shall each have the option for a period of thirty (30) days (the “Option Period”) after receipt of the Notice of Transfer to (A) if the Transfer is for all of the Transferring Shareholder’s Shares, commit to purchase all, but not less than all, of the Shares of the Transferring Shareholder on the same terms and conditions as set

forth in the Proposal, or (B) if the Transfer is a sale or exchange of less than all of the Transferring Shareholder’s Shares, elect to join in the sale or exchange; in each case by delivering written notice of its election to the Transferring Shareholder within the thirty-day period.

(ii) If the Transfer is for all of the Transferring Shareholder’s Shares, any Optionee that wishes to purchase the Transferring Shareholder’s Shares shall provide the Transferring Shareholder with a written notice specifying the number of the Transferring Shareholder’s Shares (up to such Optionee’s Pro Rata Share) which such Optionee desires to purchase, within fifteen (15) days after receipt of the Notice of Transfer, and may, at the Optionee’s option, indicate the maximum number of the Transferring Shareholder’s Shares such Optionee would purchase in excess of such Optionee’s Pro Rata Share of the Transferring Shareholder’s Shares (the “Excess Amount”). If any Optionee fails to respond within such period, such failure shall be regarded as a rejection by such Optionee of its right to participate. If one or more of the Optionees declines to participate in such purchase or elects to purchase less than such Optionee’s Pro Rata Share, then those Shares not being purchased by such Optionee (the “Excess Offered Shares”) shall automatically be deemed to be accepted by Optionees who specified an Excess Amount in their respective notice of acceptance, allocated among such Optionees (with rounding to avoid fractional shares) in proportion to their respective Pro Rata Shares determined based only on those Optionees seeking to purchase Excess Amounts but in no event shall an amount greater than any Optionee’s Excess Amount be allocated to such Optionee. This procedure shall be employed until the first to occur of the Entire Excess Amount of each Optionee being satisfied or all Excess Offered Shares have been allocated. All of such allocations must be completed within the Option Period. Unless the Optionees elect to purchase all of the Transferring Shareholder’s Shares, the Transferring Shareholder shall be entitled to sell all of the Transferring Shareholder’s Shares in the manner specified in Section 6.2(e) below and the Optionees shall have no rights with respect thereto.

(iii) If the Transfer is a sale or exchange of less than all of the Transferring Shareholder’s Shares, an Optionee may elect to join in the sale or exchange, and will be entitled to sell or exchange, pursuant to the terms of the Proposal, a number of its Shares determined by multiplying the Applicable Percentage times the number of Shares held by such Optionee. In such event, the Transferring Shareholder shall use commercially reasonable efforts to obtain the agreement of the Purchasing Party to the participation of such Optionee in the sale or exchange, but if no such agreement is obtained, the Transferring Shareholder shall not transfer any of such Transferring Shareholder’s Shares to the Purchasing Party. For purposes of this Section 6.2(c)(iii), the Applicable Percentage means a percentage determined by dividing the number of Shares the Transferring Shareholder proposes to transfer by the number of Shares held by the Transferring Shareholder.

(d) If any of the Optionees elect to purchase Shares of the Transferring Shareholder, the closing of the purchase shall take place on the date designated as the closing date of the Proposal, but in no event later than thirty (30) days after the expiration of the Option Period, in the Company offices, or at such other time and place as may be mutually agreed upon

in writing by the Transferring Holder and the Optionees; provided, however, that such period shall be extended for such period that the Optionee, if so required by applicable law, is in good faith and diligently pursuing the receipt of all required regulatory approvals for such transfer. In the event the Optionee is advised that such approvals will not be granted, it shall immediately notify the Transferring Shareholder and the Optionee’s rights hereunder with respect to such proposed Transfer shall terminate.

(e) In the event the Optionees, as a group, (i) fail to exercise the Option in full within the Option Period, or (ii) after electing to purchase the Transferring Shareholder’s Shares, fail to close the purchase hereunder (unless such failure to close is attributable to the action or inaction of the Transferring Shareholder), the Transferring Shareholder shall have the right to Transfer its Shares to the Purchasing Party designated in the Notice of Transfer in accordance with the terms of the Proposal. However, as a condition to the effectiveness of such Transfer, the Purchasing Party shall thereupon become a party to this Agreement with the same rights and obligations of the Transferring Shareholder and shall confirm such fact by executing a counterpart to this Agreement.

6.3 Prohibited Transfers. Notwithstanding anything to the contrary provided in this Agreement, the Shareholders will not Transfer any of their Shares to any person (other than to another Shareholder) (i) who is engaged or proposes to engage in activities which would be prohibited under Section 9.1(a) hereof, except in the event of a Transfer of Shares of the Company as contemplated by the Sale Agreement, or (ii) if such person’s ownership of Shares would breach the stock ownership limitations imposed upon the Shares by the United States federal communications laws or the rules and regulations promulgated by the FCC thereunder. In addition, no Shareholder (other than TEMPR) will Transfer any Shares to any direct or indirect competitor of TEMPR in Puerto Rico and TEMPR will not Transfer any of the Shares owned by it to any direct or indirect competitor of ClearComm in Puerto Rico, except in the event of a Transfer of Shares of the Company as contemplated by the Sale Agreement or in the event TEMPR or ClearComm, respectively, hold less than 20% of the capital stock of the Company.

6.4 Permitted Transfers.

(a) The Transfer restrictions provided for in this Article VI will not apply to the Transfer by any Shareholder of all, or any part of, or interest in, the Shares of the Company held by it at any time to its respective Affiliates.

(b) No Transfer pursuant to this Section 6.4 shall be effective until such transferee has executed and delivered to the Company an instrument, in the form prescribed by the Company, agreeing to be bound by this Agreement.

6.5 Waiver of Rights. The parties hereto hereby expressly agree to unconditionally and irrevocably waive all rights of first refusal, pre-emptive rights, tag-along rights or other similar rights held by such parties in the event of a Transfer of Shares by ClearComm to TEMPR pursuant to the Stock Purchase Agreement, which will be subject solely to the terms and conditions set forth therein.

ARTICLE VII

CONFLICTS WITH CERTIFICATE OF INCORPORATION AND BYLAWS

If any conflict exists between the certificate of incorporation or the bylaws of the Company and the terms of this Agreement, the Shareholders agree that the terms of this Agreement shall control and supersede the applicable provisions of the certificate of incorporation and bylaws of the Company. On Effective Date, the Shareholders will amend the bylaws to conform with the terms of this Agreement, as set forth in Exhibit D, and will consent the amendments of the certificate of incorporation set forth in Exhibit E that will have been proposed by the board of directors.

ARTICLE VIII

REGISTRATION RIGHTS

Section 8.1 Required Registration.

(a) At any time after the Effective Date, any Shareholders (the “Selling Shareholders”) may request the Company to register under the Securities Act at least the Minimum Number of Shares (the “Registrable Shares”) for sale in the manner specified in such notice. The Selling Shareholders shall be entitled to select the lead managing underwriter for any request made under this Section 8.1, which underwriter shall be reasonably satisfactory to TEMPR and ClearComm. Notwithstanding anything to the contrary contained herein, the Company shall not be required to cause a registration statement requested hereunder to become effective prior to one hundred eighty (180) days following the effective date of the most recent registration by the Company of securities under the Securities Act (other than on Form S-4 or S-8 or any successor to such forms); provided, however, that the Company shall use all commercially reasonable efforts to achieve such effectiveness promptly following such one hundred eighty (180) day period if the Selling Shareholders’ request has been made prior to the expiration of such one hundred eighty (180) day period. The Company shall not be required to effect more than one registration pursuant to this Section 8.1(a). In the event the Company shall have filed a registration statement upon the request of the Selling Shareholders pursuant to this Section 8.1(a), and a Selling Shareholder subsequently shall have withdrawn such request for registration (other than as a result of the delays contemplated by Section 8.1(b)), such withdrawn registration shall constitute the one demand registration permitted by such Selling Shareholder pursuant to this Section 8.1(a).

(b) The Selling Shareholders shall bear and pay all expenses incurred in connection with the registration, filing or qualification of Registrable Shares pursuant to this Section 8.1, including, without limitation, all registration, filing and qualification fees, printing and accounting fees relating or apportionable thereto, the fees and disbursements of counsel, underwriting discounts and commissions.

Section 8.2 Piggyback Registration.

(a) If the Company at any time (other than the initial public offering of Company Shares) proposes to register any of its securities under the Securities Act for sale to the public, whether for its own account or for the account of other shareholders or both (except with respect to registration statements on Forms ▇-▇, ▇-▇ or any successor to such forms), each such time it will give written notice to the Selling Shareholders of its intention to do so. Upon the written request of a Selling Shareholder, received by the Company within twenty (20) days after the giving of any such notice by the Company, the Company will use its commercially reasonable efforts to cause the Shares of such Selling Shareholder as to which registration shall have been so requested to be included in the securities to be covered by the registration statement proposed to be filed by the Company, all to the extent requisite to permit the sale or other disposition by such Selling Shareholder of such Shares so registered. In the event that any registration pursuant to this Section 8.2 shall be, in whole or in part, an underwritten public offering of Shares, the number of Shares of the Selling Shareholders to be included in such an underwriting may be reduced if and to the extent that the managing underwriter shall be of the opinion that such inclusion would adversely affect the marketing of the securities to be sold by the Company therein. Notwithstanding the foregoing provisions, the Company may withdraw any registration statement referred to in this Section 8.2 without thereby incurring any liability to such Selling Shareholders.

(b) In the event any Piggyback Shares are included in a registration statement under this Agreement:

(i) To the extent permitted by law, the Company will indemnify and hold harmless the Selling Shareholders and each of their respective officers and directors, any underwriter (as defined in the Securities Act) of the Selling Shareholders and each person, if any, who controls such Selling Shareholders or the underwriter within the meaning of the Securities Act or the Exchange Act (each, for purposes of this Section 8.2, an “Indemnitee”), against any losses, claims, damages or liabilities to which they may become subject under the Securities Act, or the Exchange Act or other federal or state law, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arising out of or are based upon any of the following statements, omissions or violations (collectively, a “Violation”): (A) any untrue statement or alleged untrue statement of a material fact contained in such registration statement, including any preliminary prospectus or final prospectus contained therein or any amendments or supplements thereto, (B) the omission or alleged omission to state therein a material fact required to be stated therein, or necessary to make the statements therein not misleading, or (C) any violation or alleged violation by the Company of the Securities Act, the Exchange Act, any state securities law or any rule or regulation promulgated under the Securities Act, or the Exchange Act or any state securities law; and the Company will pay to each such Indemnitee, as incurred, any legal or other expenses reasonably incurred by them in connection with investigating or defending any such loss, claim, damage, liability or action; provided, however, that this indemnity agreement shall not apply to amounts paid in settlement of any such loss, claim, damage, liability or action if such settlement is effected without the consent of the Company (which consent shall not be unreasonably withheld), nor shall the Company be liable in any such case for any such loss, claim,

damage, liability or action to the extent that it arises out of or is based upon a Violation which occurs in reliance upon and in conformity with written information furnished expressly for use in connection with such registration by any such Indemnitee.

(ii) to the extent permitted by law, each Selling Shareholder will indemnify and hold harmless the Company, each of its directors, each of its officers who has signed the registration statement, each person, if any, who controls the Company within the meaning of the Securities Act, any underwriter, any other Company shareholder selling securities in such registration statement and any controlling person of any such underwriter of such other Company shareholder, against any losses, claims, damages, or liabilities to which any of the foregoing persons may become subject under the Securities Act, or the Exchange Act or other federal or state law, insofar as such losses, claims, damages, or liabilities (or actions in respect thereto) arise out of or are based upon any Violation, in each case to the extent (and only to the extent) that such Violation occurs in reliance upon and in conformity with written information furnished by such Selling Shareholder expressly for use in connection with such registration; and such Selling Shareholder will pay, as incurred, any legal or other expenses reasonably incurred by any person intended to be indemnified hereunder, in connection with investigation or defending any such loss, claim, damage, liability, or action; provided, however, that this indemnity agreement shall not apply to amounts paid in settlement of any such loss, claim, damage, liability or action if such settlement is effected without the consent of such Selling Shareholder, which consent shall not be unreasonably withheld.

(iii) Promptly after receipt by an indemnified party of notice of the commencement of any action (including any governmental action), such indemnified party will, if a claim in respect thereof is to be made against any indemnifying party, deliver to the indemnifying party a written notice of the commencement thereof and the indemnifying party shall have the right to participate in, and to the extent the indemnifying party so desires, jointly with any other indemnifying party similarly noticed, to assume the defense thereof with counsel mutually satisfactory to the parties; provided, however, that an indemnified party (together with all other indemnified parties which may be represented without conflict by one counsel) shall have the right to retain one separate counsel, with the fees and expenses to be paid by the indemnifying party, if representation of such indemnified party by the counsel retained by the indemnifying party would be inappropriate due to actual or potential differing interests between such indemnified party and any other party represented by such counsel in such proceeding. The failure to deliver written notice to the indemnifying party within a reasonable time of the commencement of any such action, if materially prejudicial to its ability to defend such action, shall relieve such indemnifying party of any liability to the indemnified party to the extent of such prejudice, but the omission so to deliver written notice to the indemnifying party will not relieve it of any liability that it may otherwise have to any indemnified party.

(iv) the obligations of the Company and each Selling Shareholder under this Section 8.2 shall survive the completion of any offering of Shares under this Agreement and termination of this Agreement.

Section 8.3 “Market Stand-Off” Agreement. During the period of duration specified by the Company and an underwriter of Shares (or other securities convertible into Shares) of the Company (which period shall not exceed one hundred eighty (180) days), following the effective date of a registration statement of the Company filed under the Securities Act, no Shareholder shall, to the extent requested by the Company and such underwriter, directly or indirectly sell, offer to sell, contract to sell (including, without limitation, any short sale), grant any option to purchase or otherwise transfer or dispose of (other than to those who agree to be similarly bound) any Shares (or other securities convertible into Shares) of the Company held by it at any time during such period (except, (i) transfers between or among Shareholders; (ii) the Shares included in such registration; and (iii) transfers to Affiliates of the transferor).

Section 8.4 Listing. In connection with a registration pursuant to Article VIII of this Agreement, the Company will use all commercially reasonable efforts to qualify the Company stock sold pursuant to such registration to trade on a United States national securities exchange or on the National Association of Securities Dealers Automated Quotation (“Nasdaq”) system and to maintain the inclusion of such Shares on a United States national securities exchange or the Nasdaq system for a period of four years after the effective date of a registration statement filed with the SEC pursuant to this Agreement. The Nasdaq system shall mean the Nasdaq National Market.

ARTICLE IX

OTHER AGREEMENTS

Section 9.1 General. Each of the Shareholders covenants and agrees as follows:

(a) No Shareholder nor any Affiliate thereof shall, during the term of this Agreement and for a period of three years after it ceases to own any Shares, and in the service and/or geographic areas set forth and described in the terms and conditions of the Licenses or in any license or concession that is currently pending or has been requested by the Company, directly or indirectly own, manage, operate, control, finance or participate in the ownership, management, operation, control or financing of any Competing Enterprise; provided, however, that this provision shall not apply to any Shareholder’s ownership or acquisition, solely as an investment, of equity or debt securities that represent no more than three percent (3%) of the outstanding voting securities of a Competing Enterprise that is listed or admitted for trading on a securities exchange or similar system. To the extent that the covenants provided for in this Section 9.1 may later be deemed by a court to be too broad to be enforced with respect to its duration or with respect to any particular activity or geographic area, the court making such determination shall have the power to reduce the duration or scope of the provision, and to add or delete specific words or phrases to or from the provision. The provision as modified shall then be enforced.

(b) No Shareholder nor any Affiliate thereof shall, during the term of this Agreement and for a period of three years after it ceases to own any Shares, directly or indirectly, for itself or for any other Person: (i) attempt to solicit the employment of any employee of the Company, and/or (ii) call on or solicit any of the actual or targeted prospective customers or clients of the Company with regard to the sale of goods or services competitive

(c) No Shareholders nor any Affiliate thereof shall at any time divulge, communicate or use to the detriment of the Company or for the benefit of any other person or persons, or misuse in any way, the contents of this Agreement or any arrangements contemplated hereby or any confidential information pertaining to the Company or its business. Any confidential information or data now known or hereafter acquired by any Shareholder with respect to the Company and its business shall be deemed a valuable, special and unique asset of the Company that is received by any Shareholder in confidence and as a fiduciary, and such Shareholder shall remain a fiduciary to the Company with respect to all of such information.

Section 9.2 Injunction. It is recognized and hereby acknowledged by the parties hereto that a breach or violation by any Shareholder of any or all of the covenants and agreements contained in this Section 9.1 may cause irreparable harm and damage to the Company in a monetary amount which may be virtually impossible to ascertain. As a result, each Shareholder recognizes and hereby acknowledges that the Company shall be entitled to an injunction from any court of competent jurisdiction enjoining and restraining any breach or violation of any or all of the covenants and agreements contained in this Section 9.1 by the Company and/or its associates, Affiliates, partners or agents, either directly or indirectly, and that such right to injunction shall be cumulative and in addition to whatever other rights or remedies the Company may possess hereunder, at law or in equity.

Section 9.3 List of Stockholders. The Company represents and warrants to the Shareholders that the list of existing shareholders and their respective shareholding set forth on Exhibit A hereto is the full, complete and accurate list of the Company’s shareholders and there are no other shareholders of the Company.
