terms and conditions of this agreement the sole, immediate and irrevocable
option to purchase the Property, for the period from the date of this agreement
to the Option Expiry Date (as defined below), to purchase a 100% interest in the

following payments to the Vendor: 

	 	a) 	
      $150,000 cash (455702 as to $75,000 and Young as to
      $75,000) on or before January 31, 2007;

	 	 	 
	 	b) 	
      an additional $350,000 cash (455702 as to $175,000 and

(collectively, the “Purchase
Price”). 

1.02 On the Date of Closing (as defined below) the Vendor shall
be entitled to receive a royalty of 3% of “Net Smelter Returns” and a 3%

"SEC") has declared effective a Form SB-2 Registration Statement registering
common stock of the Purchaser and (b) September 1, 2007.

1.04 In this agreement, “Closing” means the completion
of the purchase and sale of the Property, and will take place at the offices of

parties hereto may determine, and the “Date of Closing” means the day on

promptly file with the SEC all documentation required by the SEC in connection
with the transaction contemplated herein. 

1.06 In the event that any cash payment due to be paid to the
Vendor is not paid to the Vendor on or before the date set out for such payment
in paragraph 1.01 hereof, this agreement shall terminate automatically, and the
Vendor shall be entitled to retain as liquidated damages, all cash payments
received from the Purchaser up to the effective date of such termination.

7

	 	(b)	
      on the Date of Closing, the Vendor shall deliver to the

The foregoing obligations shall be for the exclusive benefit of
the Purchaser and if the Vendor fails to meet any or all of the foregoing
obligations through no fault or cause of the Purchaser, the Purchaser shall have
the right to send a notice to the Vendor that this agreement is immediately
terminated because of a failure of the Vendor to meet its Closing obligations
(the "Termination Notice"), and upon delivery of the Termination Notice the
Vendor shall be required to immediately refund to the Purchaser the full
Purchase Price.

	7. 	ARBITRATION 

7.01 If there is any disagreement, dispute or controversy
(hereinafter collectively called a "Dispute") between the parties with
respect to any matter arising under this agreement or the construction hereof,
then the Dispute shall be determined by arbitration in accordance with the
following procedures: 

	 	(a) 	
      the party on one side of the Dispute shall inform the
      other party by notice of the names of three impartial and independent
      persons who are recognized experts in the area which is the subject matter
      of the Dispute; and

	 	 	 
	 	(b) 	
      the other party shall, within seven days of receipt of
      the notice, inform the party on the other side of the Dispute the name of
      the one person that it wishes to act as the sole
  arbitrator.

          The
arbitration shall be conducted in accordance with the Commercial Arbitration
Act (British Columbia) and the decision of the arbitrator shall be made
within 30 days following his being named, shall be based exclusively on the
advancement of exploration, development and production work on the Property and
not on the financial circumstances of the parties. The costs of arbitration
shall be borne equally by the parties to the Dispute unless otherwise determined
by the arbitrator in the award. 

8

	8. 	UNAVOIDABLE DELAYS

8.01 If any party should be delayed in or prevented from
performing any of the terms, covenants or conditions of this agreement by reason
of a cause beyond the control of such party, other than a lack of funds,
including fires, floods, earthquakes, subsidence, ground collapse or landslides,
interruptions or delays in transportation or power supplies, strikes, lockouts,
wars, acts of God, government regulation or interference, including but without
restricting the generality of the foregoing, forest or highway closures or any
other cause beyond such party's control, then any such failure on the part of
such party to so perform shall not be deemed to be a breach of this agreement
and the time within which such party is obliged to comply with any such term,
covenant or condition of this agreement shall be extended by the total period of
all such delays. In order that the provisions of this article may become
operative, such party shall give notice in writing to the other party, forthwith
and for each new cause of delay or prevention and shall set out in such notice
particulars of the cause thereof and the day upon which the same arose, and
shall give like notice forthwith following the date that such cause ceased to
subsist.

SCHEDULE "B" 

	 	
      TO THAT CERTAIN AGREEMENT (THE “AGREEMENT”) MADE
      AS OF THE 22ND DAY OF JANUARY, 2007 BETWEEN 455702 B.C. LTD. AND TIMOTHY
      YOUNG OF THE FIRST PART (COLLECTIVELY THE “OWNER”) AND TECTON
      CORPORATION (THE “PAYOR”) OF THE SECOND PART 
	 
	 		 

NET SMELTER RETURNS 

1. In the Agreement, “Net Smelter Returns” means the
actual proceeds received by the Payor for its own account from the sale of ore,
or ore concentrates or other products from the Property to a smelter, refinery
or other ore buyer after deduction of smelter and/or refining charges, ore
treatment charges, penalties and any and all charges made by the purchaser of
ore or concentrates, less all umpire charges which the purchaser may be required
to pay. Not less than 60 days prior to the commencement of any fiscal year of
the Payor, the Owner shall have the right to receive Net Smelter Returns in kind
for any fiscal year of the Payor. Upon the Owner giving such notice, the Owner
and the Payor shall enter into good faith negotiations with each other to settle
the manner in which the payment shall be calculated and paid, it being the
intent that the payment received in kind shall be commercially equivalent to the
payment that the Owner would have been received if it had been made in the form
of money. 

2. Payment of Net Smelter Returns by the Payor to the Owner
shall be made semi-annually within 60 days after the end of each fiscal half
year of the Payor and shall be accompanied by unaudited financial statements
pertaining to the operations carried out by the Payor on the Property. Within 90
days after the end of each fiscal year of the Payor in which Net Smelter Returns
are payable to the Owner, the records relating to the calculation of Net Smelter
Returns for such year shall be audited and any resulting adjustments in the
payment of Net Smelter Returns payable to the Owner shall be made forthwith. A
copy of the said audit shall be delivered to the Owner within 30 days of the end
of such 90-day period. 

3. Each annual audit shall be final and not subject to
adjustment unless the Owner delivers to the Payor written exceptions in
reasonable detail within six months after the Owner receives the report. The
Owner, or its representative duly authorized in writing, at its expense, shall
have the right to audit the books and records of the Payor related to Net
Smelter Returns to determine the accuracy of the report, but shall not have
access to any other books and records of the Payor. The audit shall be conducted
by a chartered or certified public accountant of recognized standing. The Payor
shall have the right to condition access to its books and records on execution
of a written agreement by the auditor that all information will be held in
confidence and used solely for purposes of audit and resolution of any disputes
related to the report. A copy of the Owner's report shall be delivered to the
Payor upon completion, and any discrepancy between the amount actually paid by
the Payor and the amount which should have been paid according to the Owner's
report shall be paid forthwith, one party to the other. In the event that the
said discrepancy is to the detriment of the Owner and exceeds 5% of the amount
actually paid by the Payor, then the Payor shall pay the entire cost of the
audit. 

4. Any dispute arising out of or related to any report,
payment, calculation or audit shall be resolved solely by arbitration as
provided in the Agreement. No error in accounting or 

2 

in interpretation of the Agreement shall be the basis for a
claim of breach of fiduciary duty, or the like, or give rise to a claim for
exemplary or punitive damages or for termination or rescission of the Agreement
or the estate and rights acquired and held by the Payor under the terms of the
Agreement. 

“GROSS OVERRIDING ROYALTY (“GORR”)” 

          Pursuant
to the Agreement to which this Schedule is attached, the Owner is entitled to a
royalty (the “GORR”) equal to 3% of the Average Appraised Value (as hereinafter
defined) of all gem and industrial diamonds recovered, sorted and graded from
the Property (the “Diamonds”), free and clear of all costs of development and
operations. 

         
“Average Appraised Value” means the average of the valuations in Canadian
dollars of the Diamonds determined by two independent graders, one appointed by
the Payor and one appointed by the Owner. Such independent graders shall be duly
qualified and accredited, and shall sort, grade and value the Diamonds in
accordance with industry standards, having regard to, but without limiting the
generality of the foregoing, the commercial demand for the Diamonds. Each
independent valuator shall value each particular classification of the Diamonds
in accordance with the industry price books, standards and formulas. The parties
acknowledge that the intention is that the GORR is to be paid to the Owner on
this basis, regardless of the price or proceeds actually received by the Payor
for or in connection with the Diamonds or the manner in which a sale of the
Diamonds to a third party is made, and without deduction. 

          The
Payor will calculate and pay the GORR to the Owner within 60 days of the end of
each calendar quarter, based on all Diamonds from the Property which were graded
in such calendar quarter. 

          The
Owner shall not be entitled to participate in the profits or be obligated to
share in any losses generated by the Payor’s actual marketing or sales
practices. 

          The
Owner shall at his election have the right to take the GORR in kind by giving
the Payor written notice of such election not less than 30 days prior to any
calendar quarter.
