 Dear [Dam]:
 
 I am writing to confirm certain items we discussed on June 21. B. Riley
 & Co. and its affiliates have, as you know, followed the stock of Alliance
 Semiconductor for many years and in the past provided published analyses and
 recommendations about the ALSC stock. We no longer recommend the stock and are
 not market makers, but continue to have an interest in the company.
 
 While we have considered your view that this business can be returned
 to profitability, we have observed the decline in both profits and revenues from
 ALSC's traditional or "core" business and have reached the tentative conclusion
 that this business is not a viable long-term enterprise for a public company. We
 have discussed this previously and today we continue to believe this is in the
 best interests of the shareholders.
 
 We have acquired over 5% of the ALSC shares and will shortly be filing
 a Schedule 13D to report our holdings and our views. As we discussed, we
 strongly feel that ALSC should consider selling or closing its traditional
 business and sell its investment holdings, distributing the proceeds to
 shareholders. We believe new, completely independent directors who share the
 view this course of action should be aggressively evaluated should become a
 majority of the ALSC board, and want to propose to you directors who intend to
 actively investigate and evaluate the course of action we favor. I would be one
 of the new directors.
 
 We believe that the selection of new directors who comprise a board
 majority will clearly signal to the market and to shareholders that ALSC is
 serious about evaluating and pursuing a new course of action. Our proposed new
 directors recognize, of course, that if a compelling case is made for a
 different approach, their views could change, and that all tax and legal
 implications of the changes we have suggested need to be reviewed.
 
 Based on our conversation, I believe you understand and are prepared to
 implement the changes in board composition we seek. In this light, we want to
 discuss with you our views on new directors, factors which might change our
 views, and alternatives for increasing shareholder value. We hope to amicably
 reach a resolution.
 
 As a precaution, however, because the deadline for nominating a slate
 of directors at the 2005 annual meeting is June 28, we presently expect to give
 formal notice that we will nominate a slate of five directors at that meeting.
 We also intend to discuss our views with other holders. Such discussions will be
 
 in full compliance with the proxy and disclosure requirements of the securities
 laws.
 
 I appreciate your time to discuss these matters and look forward to
 continuing our discussions.
 
 Very truly yours,
 
 B. RILEY & CO., INC.
 
 Bryant Riley
 Chief Executive Officer
