Dear Mr. Ardinger:

     Reference is made to that certain AMENDED AND RESTATED LOAN AND SECURITY AGREEMENT dated as of October 15, 2003 (as amended, restated or modified from time to time, the “Agreement”), between VIEWCAST.COM, INC., OSPREY TECHNOLOGIES, INC. and VIDEOWARE, INC.

Borrower and Lender desire to amend the Agreement and certain other Loan Documents effective as of the date of this letter agreement as follows:

	(1)		The term “Revolving Credit Facility” (as set forth in Section 2(b) of the Agreement) shall mean an amount not to exceed $4,000,000.00. That certain Amended and Restated Promissory Note (i.e., the “Revolving Credit Note,” as such term is defined in the Agreement) dated as of October 15, 2003 is hereby amended to reflect a notational amount of $4,000,000.00.
	(2)		The commencement date for principal payments under that certain Promissory Note (i.e., the “Term Note,” as such term is defined in the Agreement) dated as of October 15, 2003, is hereby amended from July 31, 2005 to November 30, 2005.
	(3)		Section 2(e) of the Agreement is amended in its entirety to read as follows:

Borrower shall prepay the Loans under the Revolving Credit Facility in an amount equal to $1,100,000.00 plus the outstanding principal amount of the Loans under the Revolving Credit Facility in excess of $3,500,000.00 as of the Prepayment Date from the net proceeds (the “Net Proceeds”) of: (i) any loan from a third party to Borrower or any subsidiary of Borrower, (ii) any equity offering by Borrower or any subsidiary of Borrower, and (iii) the sale of Borrower or a subsidiary of Borrower (i.e., the sale of the equity interests or substantially all of the assets of such entity). As used in this Section 2(e), the term “Prepayment Date” shall mean the date which is two (2) business days following the receipt of the Net Proceeds.

(4)

Section 2(f) of the Agreement is amended in its entirety to read as follows:

(f)
