Dear Sirs

Sale of Shares in GTN Limited (ABN 38 606 841 801)

1. Introduction

This agreement sets out the terms and conditions upon which the Vendor engages Macquarie Capital (Australia) Limited (ABN 79 123 199 548) (Lead Manager) to dispose of 89,063,081 existing fully paid ordinary shares in GTN Limited (ABN 38 606 841 801) (Company) held by the Vendor as set out in Schedule 1 (Sale Shares) (Sale) and the Lead Manager agrees to procure the disposal of the Sale Shares and to provide underwriting thereof, subject to clause 2, in accordance with the terms of this agreement.

2. Sale of shares

2.1 Sale

The Vendor agrees to sell the Sale Shares and the Lead Manager agrees to:

(a) manage the sale of the Sale Shares by procuring purchasers for the Sale Shares at the price of A\$1.90 per Sale Share (Sale Price); and
(b) subject to clause 2.7, to underwrite and guarantee the sale of the Sale Shares by purchasing at the Sale Price per Sale Share the Sale Shares which have not been purchased by third party purchasers (or the Lead Manager's Affiliates) in accordance with clause 2.1(a) as at 7:00 pm on the Trade Date (as defined in the Timetable in Schedule 2) (or such time as the parties agree in writing) (Shortfall Shares),

in accordance with the terms of this agreement. The Lead Manager acknowledges and agrees that the identity of purchasers, and the offers to them, will comply with the requirements of this clause 2 and, subject to the foregoing, may include the Lead Manager's respective Affiliates (as defined in clause 12.5).

2.2 Sale and Settlement Date

The Lead Manager will procure that the sale of the Sale Shares under clause 2.1 shall be effected:

(a) subject to clause 2.2(b), on the Trade Date, by way of one or more special crossings (in accordance with the Operating Rules of ASX) at the Sale Price, with settlement to follow on a T+2 basis in accordance with the ASX Settlement Operating Rules (Settlement Date); and
(b) in respect of any Restricted Shares (as defined in clause 2.7), in accordance with clause 2.8.

2.3 Sale Shares

Subject to clause 10, by 3.00pm on the Settlement Date, the Lead Manager shall arrange for the payment to the Vendor, or as the Vendor directs, of an amount equal to:

(a) the Sale Price multiplied by the number of Sale Shares being sold by the Vendor (excluding the number of Restricted Shares retained by the Vendor in accordance with clause 2.7, if any); less
(b) the fees payable under clause 3 (together with any GST payable on those fees),

by transfer to the Vendor's account for value (in cleared funds) against delivery of the Sale Shares (excluding the Restricted Shares, if any) being sold by the Vendor.

This payment is in addition to the payment of any Advance Amount to the Vendor pursuant to clause 2.8(a).

2.4 Timetable

The Lead Manager must conduct the Sale in accordance with the timetable set out in Schedule 1 (Timetable) (unless the Vendor consents in writing to a variation).

2.5 Account Opening

On or before the Trade Date, the Lead Manager or its nominated Affiliate will (where relevant) open respective accounts in the name of the Vendor in accordance with its usual practice, and do all such things necessary to enable it to act as Lead Manager to sell the Sale Shares in accordance with this agreement.

2.6 Manner of Sale

(a) Exempt investors and permitted jurisdictions. The Lead Manager will conduct the Sale by way of an offer only to persons:
(i) if in Australia, who do not need disclosure under Part 6D.2 of the Corporations Act 2001 (Cth) (Corporations Act); and
(ii) if outside Australia, to institutional and professional investors in the Permitted Jurisdictions (as defined below) but not elsewhere (other than the United States in accordance with this agreement) to whom offers for sale of securities may lawfully be made without requiring the preparation, delivery, lodgement or filing of any prospectus or other disclosure document or any other lodgement, registration or filing with, or approval by, a government agency (other than any such requirement with which the Vendor, in its sole and absolute discretion, is willing to comply), as determined by agreement between the Vendor and the Lead Manager.

Permitted Jurisdictions means Australia, New Zealand, Belgium, Denmark, France, Germany, Hong Kong, Ireland, Italy, Luxembourg, Malaysia, Netherlands, Norway, Singapore, Sweden, Switzerland, United Arab Emirates (excluding Dubai International Financial Centre) and United Kingdom who are entitled to participate in the Offer pursuant to the laws of the relevant jurisdiction without registration, lodgment or other formality and may also be distributed to Eligible US Fund Managers (as defined in the ECM Master Terms).

Conduct and methodology. The Sale will be conducted by the Lead Manager in accordance with the Timetable, and via a bookbuild process under which third party purchasers will be invited to lodge bids for the Sale Securities at the Sale Price. Purchasers may include the Lead Manager related bodies corporate or Affiliates.

(b) Allocations. Proposed allocations of the Sale Shares to purchasers must be made by the Lead Manager in consultation with the Vendor and its advisers.

2.7 Principal Shares

Notwithstanding anything else in this Agreement the number of Sale Shares which must be purchased by the Lead Manager under the terms of this Agreement (Principal Shares) will be the lesser of:

(a) the Shortfall Shares; and
(b) the maximum number of the Sale Shares that can be sold to the Lead Manager without breach by the Lead Manager or any of its associates of section 606 of the Corporations Act 2001 (Cth) (Corporations Act).

The Lead Manager warrants that the information it provides to the Vendor to enable it to calculate the number of Principal Shares in accordance with this clause 2.7 will, at the time it is given, be accurate. If the number of Principal Shares is less than the number of Shortfall Shares, such difference to be referred to in this Agreement as the "Restricted Shares", the Vendor agrees to retain any Restricted Shares, subject to the terms of this Agreement.

2.8 Restricted Shares

(a) Advance Amount. By 3:00pm on the Settlement Date, the Lead Manager must advance to the Vendor an amount equal to the number of Restricted Shares (if any) multiplied by the Sale Price (Advance Amount). No interest will be payable on the Advance Amount. The Vendor must only repay the Advance Amount from and to the extent that the Vendor receives the proceeds of sale of the Restricted Shares. The outstanding Advance Amount will not be repayable in any circumstances in respect of Restricted Shares not sold by the End Date (as defined in clause 2.8(c) below) and the agency provided for in clause 2.8(c) will terminate at that time or at such earlier time when all Restricted Shares have been sold. If the Vendor receives a dividend or other distribution on a Restricted Share prior to the End Date, where that dividend or distribution was announced on or after the Trade Date, then the Vendor must pay the after-tax amount of the receipt to the Lead Manager in reduction of the Advance Amount applicable to that Restricted Share.
(b) Repayment. The Lead Manager will automatically apply any proceeds of sale of the Restricted Shares as agent against repayment of the Advance Amount by the Vendor, immediately upon receipt of those proceeds.
(c) Restricted Shares. If there are Restricted Shares, then the Lead Manager will sell, as agent for the Vendor, in the ordinary course of the Lead Manager's business, the Restricted Shares by the date that is 60 Business Days after the date of this Agreement (End Date). The Vendor must comply with directions of the Lead Manager to transfer Restricted Shares in order to settle any such sale, provided that all sales must be effected by 7.00 pm on the End Date;
(d) Execution of sale of Restricted Shares. The Lead Manager agrees that the sale of the Restricted Shares will be effected by way of one or more special crossings in accordance with the Operating Rules of the ASX and the ASX Settlement Operating Rules, and/or by way of one or more regular brokered transactions on the ASX on the condition that neither it, nor any person acting on its behalf, knows, or has reason to know, that the sale has been pre-arranged with, or that the purchaser is, a person in the United States. Settlement of Restricted Shares sold in this manner will occur on a T + 2 basis, (where T represents the date on which the relevant share was sold).
(e) Indemnity for Restricted Securities. The Lead Manager must indemnify the Vendor for any shortfall between the actual price received for each Restricted Security sold (if any) as agent and the Sale Price in accordance with clause 2.8(c).

Any such indemnified amount is to be paid to the Vendor by way of reduction to the Advance Amount.

(f) Interest in Restricted Shares. The parties acknowledge that the Lead Manager does not acquire any interest in the Restricted Shares (if any) or any rights in them (by way of security or otherwise) in respect of them except as agent for the sale of those shares.

2.9 U.S. Securities Act

The Sale Shares shall only be offered and sold:

(a) to persons that are not in the United States and acquire Sale Shares in "offshore transactions" (as defined in Rule 902(h) under the U.S. Securities Act of 1933 (U.S. Securities Act)) in reliance on Regulation S under the U.S. Securities Act (Regulation S); and
(b) to persons in the United States or who are acting for the account or benefit of persons in the United States that are dealers or other professional fiduciaries organised, incorporated or (if an individual) resident in the United States that are acting for an account (other than an estate or trust) held for the benefit or account of persons that are not "U.S. persons" (as defined in Regulation S) for which they have, and are exercising, investment discretion within the meaning of Rule 902(k)(2)(i) of Regulation S (Eligible U.S Fund Managers) in reliance on Regulation S.
