                            NON-COMPETITION AGREEMENT


     THIS NON-COMPETITION AGREEMENT (this "Non-Competition Agreement") is
entered into as of the 30th day of December, 1997 by and among Emerging
Communications, Inc., a Delaware corporation ("ECI"), Atlantic Tele-Network,
Inc., a Delaware corporation (the "Company"), and Jeffrey J. Prosser,
("Prosser").

     WHEREAS, to eliminate corporate disputes and to maximize the value of the
Company for the benefit of the Company and its stockholders, the Company and its
co-chief executive officers and principal stockholders, Cornelius B. Prior, Jr.
("Prior") and Prosser, entered into a Principal Terms Agreement dated January
29, 1997 which contemplated the separation of the businesses and assets of the
Company; and

     WHEREAS, in order to accomplish such separation, the Company and ECI
entered into a Subscription Agreement (the "Subscription Agreement"), the
Company, Prior and Prosser entered into a Recapitalization Agreement (the
"Recapitalization Agreement") and the Company and ATN MergerCo. entered into an
Agreement and Plan of Merger (the "Merger Agreement"), all dated as of August
11, 1997;

     WHEREAS, Prior and the other stockholders of the Company are relying on the
covenants of ECI and Prosser in this Non-Competition Agreement in making and/or
retaining their investments in the Common Stock of the Company; and

     WHEREAS, the execution and delivery of this Non-Competition Agreement by
the parties hereto is contemplated by the Subscription Agreement and is a
condition to the Closing (as defined in the Subscription Agreement); and

     WHEREAS, each of the parties hereto desires to consummate, and will secure
substantial benefits from the consummation of, the Closing.

     NOW, THEREFORE, for and in consideration of the covenants herein contained
and subject to the conditions hereinafter set forth, the parties hereto agrees
as follows:


                                    ARTICLE I

                                   DEFINITIONS


     SECTION 1.01. Definitions. Capitalized terms used in this Non-Competition
Agreement without definition shall have the respective meanings ascribed to such
terms in the Subscription Agreement. As used in this Agreement, the following
terms have the meanings assigned to them below:

          "Competitive Business" means any business which competes anywhere in
     the world in any material respect with the conduct of the Subject Business
     by the Company or any of its Subsidiaries.

          "Confidential Information" means all information of a proprietary
     nature and documents or other tangible items that record information of a
     proprietary nature relating to the Subject Business, including without
     limitation, books, records, customer lists, vendor lists, supplier lists,
     pricing informa-


<PAGE>
                                      -2-


     tion, cost information, plans, strategies, forecasts, financial statistics,
     budgets and projections, other than any such information which is generally
     within the public domain at the time of receipt thereof by ECI or Prosser
     or at the time of use or disclosure of such information by ECI or Prosser
     (other than as a result of the breach by ECI or Prosser of its or his
     agreement hereunder).

          "Subject Business" means the business of providing telecommunications
     services (including carrying and/or terminating telecommunications
     traffic), directly or indirectly through service bureaus or other
     intermediaries, to persons who generate international audiotext
     telecommunications traffic (whether voice or data); provided, however, that
     the Subject Business shall not include the provision of any
     telecommunications services as a common carrier which does not involve the
     installation of special equipment to facilitate the generation of
     international audiotext telecommunications traffic or, directly or
     indirectly, the payment of any fee, commission or other compensation,
     through sharing of accounting or settlement rates, rate discounts or
     otherwise to persons generating such traffic.


                                   ARTICLE II

                            AGREEMENT NOT TO COMPETE;
                            DISCLOSURE OF INFORMATION


     SECTION 2.01. Agreement Not To Compete. (a) Each of ECI and Prosser
recognizes the highly competitive nature of the Subject Business and agrees that
the value and goodwill of the Company and its Subsidiaries would be
substantially impaired if it or he, as the case may be, failed to comply with
its or his obligations hereunder. Accordingly, each of ECI and Prosser hereby
agrees from the consummation of the Merger that during a period of ten years
thereafter, each of ECI and Prosser shall not, directly or indirectly, on its or
his own behalf, as the case may be, or on behalf of any other person or entity:

          (i) engage in any Competitive Business, whether such engagement shall
     be as an employer, officer, director, owner, employee, partner, advisor,
     consultant, stockholder, investor, agent or other participant in any
     Competitive Business (or in any similar capacity in which it or he, as the
     case may be, derives an economic benefit from a Competitive Business);

          (ii) assist others in engaging in any Competitive Business in the
     manner described in the foregoing clause (i);

          (iii) solicit, entice or induce any director, employee, consultant or
     other agent of the Company or any current or future Subsidiary of the
     Company materially involved in the Subject Business to terminate his or her
     employment or other relationship with the Company or such current or future
     Subsidiary or to engage in any Competitive Business;

          (iv) solicit, entice or induce any vendor or distributor of the
     Company or any current or future Subsidiary materially involved in the
     Subject Business to terminate or materially diminish its relationship with
     the Company or such current or future Subsidiary; or

          (v) solicit, entice or induce any subscriber or customer of the
     Company or any current or future Subsidiary of the Company with respect to
     the Subject Business to purchase the products or


<PAGE>
                                      -3-


     services of any Competitive Business, or to cease purchasing the services
     of the Subject Business from the Company or any current or future
     Subsidiary of the Company.

     (b) Anything contained in this Non-Competition Agreement to the contrary
notwithstanding, no provision of this Agreement shall prohibit (i) ECI or
Prosser from owning, as a passive investment, in the aggregate less than 5% of a
class of publicly-traded securities issued by any person or entity engaged in a
Competitive Business or (ii) the provision of services by ATNCO, VITELCo or VCI
pursuant to terms of the Technical Assistance Agreement.

     SECTION 2.02. Disclosure of Information. From and after the date hereof,
each of ECI and Prosser shall hold in strict confidence and shall not use or
disclose to any person, firm, corporation or other business entity, except as
required by law or judicial process, any Confidential Information for any reason
or purpose whatsoever, nor shall ECI or Prosser make use of any of the
Confidential Information for ECI's or Prosser's purposes or for the benefit of
any person or entity except the Company or any affiliate thereof.

     SECTION 2.03. Acknowledgment. Prosser acknowledges that the provisions of
this Agreement are not designed to prevent Prosser from earning a living or
fostering his own career. The provisions of this Agreement are designed to
prevent any Competitive Business from gaining unfair advantage from Prosser's
and ECI's knowledge of confidential and proprietary information relating to the
Subject Business.


                                   ARTICLE III

                            MISCELLANEOUS PROVISIONS


     SECTION 3.01. Remedies. Each of ECI and Prosser acknowledges that a remedy
at law for any breach or threatened breach of the provisions of this
Non-Competition Agreement would be inadequate and therefore agrees that the
Company shall be entitled to injunctive relief; provided, however, that nothing
contained herein shall be construed as prohibiting the Company from pursuing any
other remedies available for any such breach or threatened breach.

     SECTION 3.02. Benefits. This Non-Competition Agreement and the rights and
obligations of the parties hereto shall bind and inure to the benefit of any
successor or successors of the Company by reorganization, merger or
consolidation or otherwise and any assignee of all or substantially all of its
business and properties.

     SECTION 3.03. Severability, Blue Penciling. It is the desire and intent of
the parties hereto that the provisions of this Non-Competition Agreement shall
be enforced to the fullest extent permissible under the laws and public policies
applied in each jurisdiction in which enforcement is sought. Accordingly, if any
particular provision of this Non-Competition Agreement shall be adjudicated to
be invalid or unenforceable, such provision shall be deemed amended to delete
therefrom the portion thus adjudicated to be invalid or unenforceable, such
deletion to apply only with respect to the operation of such provision in the
particular jurisdiction in which such adjudication is made. In addition, if any
one or more of the provisions contained in this Non-Competition Agreement shall
for any reason be held to be excessively broad as to duration, geographical
scope, activity or subject, it shall be construed by limiting and reducing it so
as to be enforceable to the extent compatible with the applicable law as it
shall then appear.
