      NOW, THEREFORE, in consideration of the covenants, promises and
representations set forth herein, and for other good and valuable consideration,
the receipt and sufficiency of which are hereby acknowledged, the parties hereby
agree as follows:

                                   ARTICLE I
                               EXCHANGE OF SHARES

      1.1   Transaction. The Shareholders hereby agree to tender the ATN Shares
to the Company and, in exchange therefor, the Company shall issue to the
Shareholders in a transaction exempt from the registration and prospectus
delivery requirements of the Securities Act of 1933, as amended (the

                                       1
<PAGE>
"Securities Act"), the GTN Shares in accordance with Schedule I attached hereto
and the Exchange Notes in accordance with Schedule II attached hereto.

      1.2   Consideration. In consideration and exchange for the GTN Shares and
the Exchange Notes to be issued by the Company, each Shareholder shall surrender
to GTN all of his, her or its interest in and to the ATN Shares held by such
Shareholder as set forth on Schedule I attached hereto.

      1.3   Exchange Notes. The Company shall deliver to each Shareholder an
Exchange Note, substantially in the form attached hereto as Exhibit A, in the
original principal amount set forth on Schedule II opposite such Shareholder's
name, which shall bear no interest and shall be due and payable on the closing
date of the IPO.

      1.4   Exchange of Certificates.

            (a)   Shareholders to Deliver ATN Shares. Simultaneously with the
execution of this Agreement, each Shareholder shall deliver to the Company, in
exchange for the GTN Shares, all of the certificates representing his, her or
its ATN Shares duly endorsed for transfer to the Company, to be held in escrow
by the Company until the earlier of (i) the date of execution of the
Underwriter's Agreement by and between the Company and Feltl and Company (either
on behalf of Feltl and Company or as representative of several underwriters) or
its representative, with respect to the IPO (the "Effective Date") or (ii) the
termination of this Agreement pursuant to Section 5.1. In the event of a
termination pursuant to Section 5.1, the Company shall return the certificates
to each Shareholder within ten (10) days of any such termination.

            (b)   Company to Deliver GTN Shares. In exchange for the ATN Shares,
the Company shall deliver to each Shareholder a certificate representing his,
her or its GTN Shares within five (5) days of the Effective Date.

      1.5   Restrictions on Transfer; Legends. The GTN Shares will not be
transferable except (1) pursuant to an effective registration statement under
the Securities Act of 1933, as amended (the "Securities Act") or (2) upon
receipt by the Company of a written opinion of counsel, reasonably satisfactory
to the Company, that is knowledgeable in securities laws matters to the effect
that the proposed transfer is exempt from the registration requirements of the
Securities Act and relevant state securities laws. Restrictive legends must be
placed on all certificates representing the GTN Shares, substantially as
follows:

      "THESE SECURITIES HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF
      1933, AS AMENDED (THE "SECURITIES ACT"), OR THE SECURITIES LAWS OF ANY
      STATE, AND ARE BEING OFFERED AND SOLD PURSUANT TO AN EXEMPTION FROM THE
      REGISTRATION REQUIREMENTS OF THE SECURITIES ACT AND SUCH LAWS. THESE
      SECURITIES MAY NOT BE SOLD OR TRANSFERRED EXCEPT PURSUANT TO AN EFFECTIVE
      REGISTRATION STATEMENT UNDER THE SECURITIES ACT OR PURSUANT TO AN
      AVAILABLE EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THE SECURITIES
      ACT OR SUCH OTHER LAWS."

Each Shareholder understands and acknowledges that the Company has not agreed to
register the GTN Shares for distribution in accordance with the Securities Act
or state law, and that the Company has not agreed to comply with any exemption
under the Securities Act or state law for the resale of the GTN Shares. Each
Shareholder understands and acknowledges that the Company has no obligation to
undertake or complete a public offering of its securities and that even if a
public offering is undertaken

                                       2
<PAGE>
and successfully completed, the GTN Shares received hereby will remain subject
to the restrictions on transferability described in this Agreement. If no public
offering is undertaken and completed, the Shareholders may never be able to sell
their GTN Shares pursuant to Rule 144 under the Act. Each Shareholder further
understands and acknowledges that the Company currently does not file periodic
reports with the Securities and Exchange Commission pursuant to the requirements
of Sections 13 or 15(d) of the Securities Exchange Act of 1934, as amended, and
may not be obligated to file such reports at any time in the future. Therefore,
the Shareholders may never be able to sell their shares pursuant to Rule 144
under the Act.

                                   ARTICLE II
                      TERMINATION OF SHAREHOLDER AGREEMENTS

      2.1   Current Shareholders. Each Shareholder hereby represents that
Schedule I accurately represents the current ownership of all issued and
outstanding shares of ATN held by such party, and that to such party's knowledge
it has no other shares, or rights to acquire shares, of ATN outstanding or
rights with respect to the ATN Shares relating to the voting or disposition
thereof, except, in the case of Yde and Gilligan, for the Amendment to Option
Agreement by and between Yde and Gilligan dated November 18, 2005 or as
referenced herein.

      2.2   The 1997 Agreement. Effective on the Effective Date, ATN, Yde,
Gilligan and Questcom hereby terminate the 1997 Agreement. Each party to the
1997 Agreement hereby forever, fully and unconditionally waives, releases and
discharges each other party and its predecessors, successors, parent entities,
subsidiaries, affiliates, agents, attorneys, officers, employees, directors,
shareholders, members and assigns (in their roles as such but not individually
unless expressly a party hereto, the "Parties") from all obligations, offsets,
actions, suits, debts, sums of money, contracts, covenants, agreements,
promises, legal rights, claims, counterclaims, causes of action, demands,
damages, costs, compensation, liabilities, losses and expenses of any nature or
of any kind, whether known or unknown, asserted or unasserted, liquidated or
unliquidated, absolute or contingent, accrued or nonaccrued, which any of the
parties ever had, now have, hereafter may have or claim to have, whether
grounded in law or equity, in contract or in tort, by statute or otherwise
against the Parties with respect to the 1997 Agreement.

      2.3   The 1998 Agreement. Effective on the Effective Date, ATN, Yde,
Gilligan, Questom and Metro hereby terminate the 1998 Agreement. Each party to
the 1998 Agreement hereby forever, fully and unconditionally waives, releases
and discharges the Parties from all obligations, offsets, actions, suits, debts,
sums of money, contracts, covenants, agreements, promises, legal rights, claims,
counterclaims, causes of action, demands, damages, costs, compensation,
liabilities, losses and expenses of any nature or of any kind, whether known or
unknown, asserted or unasserted, liquidated or unliquidated, absolute or
contingent, accrued or nonaccrued, which any of the parties ever had, now have,
hereafter may have or claim to have, whether grounded in law or equity, in
contract or in tort, by statute or otherwise against the Parties with respect to
the 1998 Agreement.

similar laws relating to, or affecting generally the enforcement of, creditors'
rights and remedies or by other equitable principles of general application.

            (b)   Neither the execution and delivery of this Agreement, nor the
