For minerals that Quaterra produces from the lands included in the Exploration Permits, Quaterra shall pay to Snowdon a royalty in the amount equal to twenty-five percent  (25%) of the amount of the royalty that Quaterra pays to the State of Arizona for such production.  The royalty to be paid by Quaterra to Snowdon hereunder shall be due and payable within thirty (30) days after Quaterra pays the royalty to the State.   Such royalty payments made by Quaterra to Snowdon are the total royalty payments that Quaterra is obligated to pay to Snowdon, Eagle Hill LLC and Eagle Hill Corp.





e.           Royalty Payments to Limestone.





From the royalty that Snowdon receives from Quaterra for mineral production from the lands included in any or all of the Exploration Permits, minus the 1% net smelter return royalty that Snowdon pays to Eagle Hill Corp, Snowdon agrees to pay to Limestone 20% of that remainder received by Snowdon.  The royalty to be paid by Snowdon to Limestone shall be due and payable within thirty (30) days after Quaterra pays its royalty to Snowdon.








f.           Royalty Payments to Eagle Hill Corp.

The royalty payments to be made by Snowdon to Eagle Hill Corp set forth in Section 3f above shall terminate when such total payments to Eagle Hill Corp total Four Hundred Thousand Dollars ($400,000.00), and all obligations of the Parties under the Snowdon Agreement shall be deemed satisfied.





h.           Payment of Royalty.

Any adjustments of the royalty payments due shall be made within thirty (30) days from the completion of any annual audit by the recipient of such payments, which audit shall be completed for each year on or before March 1 for the previous calendar year.  The recipients of such payments may, in their sole discretion and expense, conduct such an annual audit of the relevant accounts and books relating to such production, but in the event such party elects not to conduct such an audit by March 1 of any year, then such party shall have waived its right to dispute the amount of the royalty for that previous year.  Each Party hereto agrees to treat all information received hereunder as confidential and not to disclose the same without prior written permission of the other Parties.





i.           Method of Making Payments.





All payments required hereunder may be mailed or delivered to the addresses set forth in Section 9 hereof or to any other address as the payee may instruct in writing.  Upon making royalty payments to Snowdon, Quaterra shall be relieved of any responsibility for the distribution of payments to Limestone and Eagle Hill Corp.  The delivery or the deposit in the mail of any payment hereunder on or before the due date thereof shall be deemed timely payment hereunder.





j.           Fractional Interest.





All payments under this Agreement, unless specified otherwise, are based on the grants by the Permittees and Snowdon of their respective full undivided rights and title to the Exploration Permits, and to any Mineral Leases issued for such Permits, subject to the rights of, and obligations owed to, the State of Arizona.   If such rights and titles are less than such full interest, all payments made hereunder shall be paid in the same proportion thereof as the respective undivided rights and title actually owned by the Permittees and Snowdon bear to the entire undivided rights and title to such Permits or the areas included therein.





4.           Inspection and Reports.





Permittees and Snowdon (or their respective agent with authorization in writing), at their or their respective agents’ risk and expense, may enter upon the Permitted Property to inspect the same at such times and upon such notice to Quaterra as shall not, in Quaterra’s reasonable opinion, unreasonably or unnecessarily interfere with the operations of Quaterra.

All work performed by Quaterra on Permitted Property pursuant to this Agreement shall be done in a good and workmanlike manner and in compliance with all state or federal laws and regulations governing such operations.  Quaterra shall further comply with all the terms and any special conditions imposed by the State of Arizona under the Exploration Permits or any resulting Mineral Lease(s).  Any bonds required by the State of Arizona, as well as any reclamation bonds in addition to those already posted by Permittees, shall be posted and paid for by Quaterra, except that any bonds required from Permittees prior to the Effective Date shall remain their own responsibility.  Quaterra shall be responsible for reclamation and bonding for its operations as required by a state-approved reclamation plan.








b.           Work Commitment.





Quaterra shall be required to spend in work on the Permitted Property or make the payments in lieu thereof, the amounts required by such Permits.  Quaterra shall deliver to Permittees and Snowdon copies of exploration data for such lands consisting of geological maps, drill hole location maps, drill hole data, and technical data sheets annually.  The Parties receiving such information agree to treat all such information received hereunder as confidential and not to disclose the same without prior written permission of Quaterra.





c.           Payment of Taxes.





Quaterra shall pay all taxes levied against its improvements on the land subject to the Exploration Permits.  If the land subject to the Exploration Permits is placed into production, Quaterra shall pay all ad valorem taxes assessed against Quaterra’s interests in the land subject to the Exploration Permits used in commercial development and shall, in addition, pay all taxes related to production of minerals from such land.  In no event shall Quaterra be liable for any taxes levied or measured by income of Permittees or Snowdon , or for taxes applicable to or levied against or based upon royalty payments made to Permittees or Snowdon under this Agreement.  Quaterra shall have the right to contest, in the courts or otherwise, the validity or amount of any taxes or assessments before it shall be required to pay the same.





6.           Title Matters.





a.           Representations and Warranties.

b.           Title Documents; Data.





Upon written request of Quaterra at any time during the term hereof, Permittees and Snowdon shall promptly deliver to Quaterra all abstracts of title to and copies of all title documents affecting their respective Exploration Permits that Permittees or Snowdon have in their possession.  If Permittees or Snowdon are in possession or know the whereabouts of technical data concerning their respective Exploration Permits, Permittees and Snowdon shall furnish copies of such materials to Quaterra upon execution of this Agreement.





c.           Title Defects, Defense and Protection.
