("TSI") in connection with a merger (the "Merger") between TSI and TSI Med Acquisition Corp. ("Merger Sub"), a wholly owned subsidiary of the Company. The

Page 3 of 6

CUSIP No. 983756 10 7

TSI shares exchanged by Mr. Moll were held by Mr. Moll for his own benefit and have been cancelled in connection with the Merger.

Also in connection with the Merger, the Company issued to Mr. Moll options to purchase 500,000 Company Shares at a price of $0.50 per share and expiring on May 31, 2009 in exchange for options issued by TSI to purchase 500,000 shares of TSI common stock at the same exercise price and expiration date. The TSI options exchanged by Mr. Moll were held by Mr. Moll for his own benefit and have been cancelled in connection with the Merger.

ITEM 4. PURPOSE OF TRANSACTION

On September 13, 2004, TSI merged with and into Merger Sub pursuant to an Agreement and Plan of Merger (the "Merger Agreement") between the Company, Carlo Civelli, Bruno Mosimann, TSI and Merger Sub, dated effective August 12, 2004. On September 15, 2004, Merger Sub was merged with and into the Company and the Company changed its name from Relay Mines Limited to XLR Medical Corp. The purpose of the Merger was to allow the Company to acquire rights to a technology being developed by Exelar Medical Corporation, a joint venture corporation set up by TSI and Exelar Corporation, and to allow TSI to access public equity markets.

In connection with the Merger, each share of TSI common stock was exchanged for one Company Share and each option and warrant to acquire TSI common stock (the "TSI Options") was exchanged for options and warrants to acquire Company Shares on the same terms and conditions and with the same exercise price as the TSI Options. As a result, Mr. Moll exchanged 2,570,000 shares of TSI common stock and TSI Options to acquire 500,000 shares of TSI common stock at an exercise price of $0.50 per share for 2,570,000 Company Shares and options to acquire 500,000 Company Shares at the same exercise price. As a result of the Merger, Mr. Moll is now the beneficial owner, as that term is defined by section 13(d) of the Securities Exchange Act of 1934 and Regulation 13D thereto, of 13.1% of the Company's common stock.

Also in connection with the Merger, effective on September 13, 2004, Mr. Civelli resigned as President, Principal Executive Officer, Treasurer, Principal Financial Officer and as a director of the Company and Mr. Mossiman resigned as Secretary and as a director of the Company and new officers and directors were appointed as follows:

Name	Position(s)
Logan Anderson	President, Principal Executive Officer, Treasurer, Principal Financial Officer and a Director
Derek Van Laare	Secretary
Harold Moll	Director
Peter Hogendoorn	Director

The Bylaws of the Company were amended and restated on September 12, 2004 in order to adopt a form of Bylaws consistent with those of TSI. The Company believes that the amendments to its Bylaws do not create a material impediment to any person seeking to acquire control of the Company.

(a)	Aggregate Beneficial Ownership:

	As of September 13, 2004, Mr. Moll beneficially owns the following securities of the Company:


Title of Security	Amount	Percentage of Shares of Common Stock

Under Rule 13d-3, a beneficial owner of a security includes any person who, directly or indirectly, through any contract, arrangement, understanding, relationship, or otherwise has or shares: (i) voting power, which includes the power to vote, or to direct the voting of shares; and (ii) investment power, which includes the power to dispose or direct the disposition of shares. Certain shares may be deemed to be beneficially owned by more than one person (if, for example, persons share the power to vote or the power to dispose of the shares). In addition, shares are deemed to be beneficially owned by a person if the person has the right to acquire the shares (for example, upon exercise of an option) within 60 days of the date as of which the information is provided.

The number of Company Shares listed as beneficially owned by Mr. Moll include 2,570,000 Company Shares and options to acquire 500,000 Company Shares exercisable at $0.50 per share.
