• Guyana Frontier has agreed to spend a minimum of 80% of the proceeds of the Placement on further exploration of its Marudi Mountain property;
• Guyana Frontier has granted Teck the right to maintain its percentage shareholding in Guyana Frontier by participating in future equity financings (at a level equal to Teck's then shareholding) for a period of two years, to be extended for a period of two additional years (four years total) should Teck exercise the Warrants;
• Guyana Frontier has granted Teck a right of first offer with respect to its interest in the Marudi Mountain property;

B Property Option

In consideration of the placement, Guyana Frontier has granted Teck the exclusive option (the "B Property Option") to acquire a 51% interest in Guyana Frontier's interest in one of the B Properties.  Upon the exercise of the B Property Option in respect of any one of the B Properties, the B Property Option will terminate and Teck will have no further rights in respect of the other B Properties.

The B Properties consist of the Five Star, Whana, Aunama, Masawaki, Arawini and Otomung properties. Guyana Frontier's interest in each of the B Properties is subject to existing option agreements with Mulgravian.

Teck may elect to exercise the option with respect to a particular B Property up to the earlier of December 31, 2014, or 90 days after the date Guyana Frontier delivers a notice of completion of a minimum of $1,500,000 of exploration expenditures on such B Property, calculated from the date of execution of the letter agreement, together with all the exploration results thereof. Expenditures shall include expenditures incurred by Mulgravian on such B Property.

If Teck wishes to exercise the B Property Option, it must exercise, or have exercised, all of the Warrants for gross proceeds of $4,200,000 to Guyana Frontier within two years of the Closing Date.

If Teck elects to exercise the B Property Option with respect to a B Property, it may acquire an undivided 51% interest in Guyana Frontier's interest in such property as follows:

• If the B property is under option by Guyana Frontier to Mulgravian, and Mulgravian ceases to solely finance exploration, by Teck financing the first $3,000,000 of required contributions of Guyana Frontier under the joint venture with Mulgravian in respect of such B Property;
• If the B Property is not under option to a third party, by financing the next expenditures on the property equal to 2.5 times Guyana Frontier's or Mulgravian's expenditures on the B Property from the date of the Letter Agreement, subject to a minimum of $1,500,000 and a maximum of $4,250,000 (being 2.5 times the $1,500,000 of expenditures required for the delivery of notice by Guyana Frontier); and
• Upon completion of the above expenditures on the B Property and delivery of notice of such to Guyana Frontier, Teck shall have earned a 51% interest in Guyana Frontier's interest in the B Property. Following the exercise of the B Property Option, Guyana Frontier and Teck will participate in a joint venture in respect of their collective interest in the B Property, which interest may be subject to the prior interest of Mulgravian, if any.

A finder's fee of 300,000 common shares of Guyana Frontier is payable to Mulgravian as finder for the Placement.
