PLEDGE AND SECURITY AGREEMENT

Exhibit 10.2

PLEDGE AND SECURITY AGREEMENT

Agreement made this 24th day of October, 2005, by and between PS IVANHOE, LLC, a California limited liability company (the “Creditor”), and PRICESMART, INC., a Delaware corporation, (the “Debtor”).

NOW, THEREFORE, in consideration of the mutual covenants herein, the parties hereto agree as follows:

1. Creation of Security Interest. Debtor hereby grants to Creditor a security interest in all of the Debtor’s right, title, and interest now owned or acquired in the future in and to the following described collateral (the “Collateral”) in order to secure the payment and performance of the obligations described in paragraph 2 below:

(a) All of the issued and outstanding shares of stock (and all ownership rights with respect thereto) in PriceSmart Real Estate, S.A., a Panamanian corporation (the “Company”).

(b) Any substituted or additional Collateral supplied under the provisions of this Agreement.

2. Secured Obligations of Debtor. The Collateral secures and shall hereafter secure the payment to Creditor of all indebtedness now or hereafter owed to Creditor by Debtor under a promissory note of even date herewith (the “Promissory Note”) given by Debtor in the face amount of Twelve Million, Five Hundred Thousand Dollars ($12,500,000.00), together with any interest thereon and extensions, modifications, and renewals thereof. Debtor shall also reimburse Creditor for any and all amounts expended by Creditor in accordance with, or in the enforcement (judicially or otherwise) or exercise of, its rights under the terms of this Pledge and Security Agreement, including attorneys fees, which amounts are included in the obligations secured herein.

3. Distributions. So long as no default, and no condition or event which with notice or lapse of time, or both, would constitute a default, shall have occurred or exist under this Agreement, Debtor shall be entitled to receive all distributions (including cash and property) with respect to the Collateral; provided, however, that any distributions from the liquidation of the Collateral shall be paid to Creditor to the extent of unpaid principal and accrued unpaid interest under the Promissory Note. Upon the occurrence of a default or any condition or event which with notice or lapse of time, or both, would constitute a default hereunder, Creditor shall thereafter receive, and may apply, all distributions with respect to the Collateral against the indebtedness secured hereunder.

4. Reorganizations, etc. If, while this Agreement is in effect, any reclassification, readjustment, reorganization, merger, consolidation, or other change in the capital structure, including the creation of any subscription or other rights or other Collateral as defined in subparagraph 1(b), including additional shares of stock, is declared or made, or proposed to be declared or made, by the Company, all substituted and additional securities issued with respect to the Collateral shall be endorsed in blank by Debtor promptly upon receipt thereof or otherwise appropriately transferred to Creditor in negotiable form, and all certificates or instruments evidencing the terms of this Agreement in the same manner as and as a part of the Collateral. If no security evidences such Collateral, whichever party receives notice of the creation of such rights shall promptly notify the other party to this Agreement and Creditor shall hold such rights as Collateral, subject to the terms of this Agreement. Debtor shall have the right to exercise any subscription or other rights with respect to any Collateral, with the prior written approval of such exercise by Creditor; provided, however, that any securities which may be issued upon exercise of any such rights shall be delivered to Creditor, to be included in the Collateral.

5. Voting Rights. So long as no default and no condition or event which with notice or lapse of time or both would constitute a default shall have occurred or exist under this Agreement, Debtor shall have all voting rights with respect to the Collateral. However, upon the occurrence of a default or any such condition or event, Creditor shall thereafter have all such voting rights.

6. Representations and Warranties. Debtor represents that as of the date of this Pledge and Security Agreement (a) Debtor is the sole owner of the Collateral and that Debtor has not otherwise assigned or transferred, and agrees that Debtor shall not assign or transfer, absolutely or for security, the Collateral or any interest therein to any other person or entity; (b) there are no outstanding options, warrants or other agreements with respect to the Collateral; and (c) the execution and delivery of this Agreement by Debtor will not result in a violation of any mortgage, indenture, contract, instrument, judgment, decree, order, statute, rule or regulation to which Debtor is subject.

7. Default and Remedies. Any breach of or event of default under the Promissory Note or any failure to comply with any of the terms under this Agreement shall be a default hereunder. Upon any default hereunder, Creditor shall have the right to exercise its remedies as a secured party with respect to the Collateral, including, without limitation, the right to use all or any portion of the Collateral in Creditor’s sole and absolute discretion (a) toward cure of the default; (b) in payment of principal (whether or not otherwise accelerated) and/or interest; or (c) in such combination thereof as Creditor may determine. Creditor shall in no event be required to use proceeds of the Collateral to cure a default.

8. Administration of Collateral. The provisions set forth below shall govern the administration of the Collateral:

(a) Further Documents. Debtor will forthwith upon request by Creditor and in confirmation of the security interest hereby created, execute and deliver to Creditor such further assignments, transfers, assurances, instruments, notices and agreements in form and substance as the Creditor shall reasonably request.

(b) Remedies. In addition to any rights and remedies otherwise available in law or in equity, and in addition to the other provisions of this Agreement, and any other documents or instruments delivered or to be delivered in connection herewith or therewith, or any document or instrument now in existence, or which may hereafter be made, with respect to the Promissory Note, the provisions set forth below shall, to the extent permitted by applicable law, govern Creditor’s rights to foreclose on the Collateral upon a default hereunder.

(c) Conduct of Sale. Upon giving written notice of default to Debtor pursuant to the terms of this Agreement, Creditor may sell the Collateral as is required to produce net funds sufficient to pay Creditor the full amount of the Promissory Note and other secured obligations under paragraph 2 herein.

(d) Sale or Disposition. Upon any sale or disposition, Creditor shall have the right to deliver, assign, and transfer to the purchaser thereof the Collateral so sold or disposed. Each purchaser at any such sale or other disposition shall hold the Collateral free from any claim or right of whatever kinds, including any equity or right of redemption of the Debtor. The Debtor specifically waives all rights of redemption, stay or appraisal which it has or may hereafter have under any rule of law or statute now existing or hereafter adopted.

(f) Severability. If any provision of this Agreement shall be deemed or held to be invalid or unenforceable for any reason, such provision shall be adjusted, if possible, rather than voided, so as to achieve the intent of the parties to the fullest extent possible.
