Boxingtalk has obtained the following copy of a letter sent to Diego Corrales by an attorney for Gary Shaw Productions...   Dear Mr. Corrales: Please be advised that this firm represents Gary Shaw Productions, LLC (“Shaw”) and Antonio Leonard Productions (“Leonard”). We have been asked to respond to your letter dated November 15, 2006. In response to your request, we provide a copy of the fully-executed Promotional Rights Agreement between Shaw, Leonard, Prince Boxing Enterprises, Ltd. and Diego Corrales (the “Contract”). Notice has been received that the Contract has been violated by the execution of an agreement between you and Golden Boy Promotions. We have been directed to institute suit against all persons and entities who have caused, or promoted, the wrongful interference with Shaw’s and Leonard’s rights under the Contract. This letter is written without prejudice to, or a waiver of, Shaw’s and Leonard’s rights and claims. Very truly yours, Peter R. Bray
