THIS AMENDMENT (the “Amendment”) is to a PURCHASE
AGREEMENT (the “Agreement”) that was dated and executed as of October 27, 2008,
and a Debt Settlement Agreement dated and executed on July 9, 2009 that was
entered into by and among Lexaria Corp., a Nevada corporation with headquarters
located at #950-1130 West Pender Street, Vancouver, British Columbia Canada V6E
4A4 (the “Company”), and Morgan Bunka of 2316 Bella Vista Street, Kelowna BC V1P
1S1, and any additional purchasers who executed the Agreement.

W I T N E S E T H: 

WHEREAS, the Purchaser has purchased an 18.0% Secured
Promissory Note of the Company (the “Note”), subject to and upon the terms and
conditions of the October 27, 2008 Agreement; and 

WHEREAS, the Purchaser and
the Company wish to extend the Agreement and the Note beyond their originally
contemplated expiration date of October 27, 2010 upon the terms and conditions
as noted herein. 

WHEREAS, the Company is
indebted to the Purchaser in the amount of CAD$194,188.75 as specified on Debt
Settlement Agreement dated July 9, 2009. 

NOW THEREFORE, in
consideration of the premises and the mutual covenants contained herein and
other good and valuable consideration, the receipt and sufficiency of which are
hereby acknowledged, the parties agree as follows: 

1.     AGREEMENT TO EXTEND THE AGREEMENT. 

The Purchaser and the Company
agree to extend the original terms of the Agreement on a month-to-month basis,
under the identical terms as contained in the original Agreement wherever
logically possible. 

The Company agrees to use a
reasonable fraction of contemplated cash flows from existing oil wells at
Belmont Lake, such amount not to cause undue hardship to the Company’s
operations, to repay the Purchaser on a regular basis, a portion of the
aggregate amount of CAD$194,188.75 if and as possible, until such time as the
CAD$194,188.75 principal amount has been completely repaid. 

The Company agrees to continue to
pay the agreed upon interest rate on all unpaid balances, and to otherwise
respect the terms of the Agreement and the Note. 

All representations and covenants
and acknowledgements and indemnifications of the original Agreement and Note
remain in force, wherever it is logically possible.

of the parties hereto. 

4.     All pronouns and any
variations thereof refer to the masculine, feminine or neuter, singular or

transmission of this signed Agreement shall be legal and binding on all parties
hereto.

6.     This Agreement may be
signed in one or more counterparts, each of which shall be deemed an
original.

7.     If any provision of
this Agreement shall be invalid or unenforceable in any jurisdiction, such
invalidity or unenforceability shall not affect the validity or enforceability
of the remainder of this Agreement or the validity or enforceability of this
Agreement in any other jurisdiction.

8.     This Agreement may be
amended only by an instrument in writing signed by the party to be charged with
enforcement thereof.

IN WITNESS WHEREOF, this
Agreement has been duly executed by the Purchaser and the Company as of
October 21, 2010.
