Description of Committees of the Board of Directors

The board of directors has established a Compensation Committee and an Audit Committee.  The composition and function of these committees are set forth below.  

Audit Committee

The Company’s Audit Committee is comprised of Allan D. Anderson (Chair), Gervaise Wilhelm and Jeffrey A. Zinnecker.  The Audit Committee assists the board by reviewing the integrity of the Company’s financial reporting processes and controls; the qualifications, independence and performance of the independent auditors; and compliance by the Company with certain legal and regulatory requirements.  The Audit Committee has the sole authority to retain, compensate, oversee and terminate the independent auditors.  The Audit Committee reviews the Company’s annual audited financial statements, quarterly financial statements and filings with the Securities and Exchange Commission.  The Audit Committee reviews reports on various matters, including critical accounting policies of the Company, significant changes in the Company’s selection or application of accounting principles and the C ompany’s internal control processes.  The Audit Committee also pre-approves all audit and non-audit services performed by the independent auditor.  The Committee acts under a written charter first adopted and approved by the board of directors on April 27, 2000 and most recently amended on December 11, 2003.  A copy of the current Audit Committee Charter is attached as Appendix A to the proxy statement for the Company’s 2004 Annual Meeting of Shareholders.  During the fiscal year ended September 30, 2005, the Audit Committee met four times.

The board of directors has determined that all members of the Audit Committee are “independent” directors under the Nasdaq Marketplace Rules and the rules of the Securities and Exchange Commission.  The Company’s board of directors has reviewed the education, experience and other qualifications of each of the members of its Audit Committee.  After review, the board of directors has determined that Mr. Anderson meets the Securities and Exchange Commission definition of an “audit committee financial expert.”  A report of the Audit Committee is set forth below.

Compensation Committee

The Compensation Committee reviews and makes recommendations to the board concerning salaries, bonus awards and benefits for officers and key employees.  Members of the Compensation Committee are Allan D. Anderson, Gervaise Wilhelm and Jeffrey A. Zinnecker.  During fiscal year ended September 30, 2005, the Compensation Committee met twice.

Nomination and Shareholder Communications Processes

The Company does not currently have a nominating committee.  The board as a whole performs certain of the functions typical of a nominating committee, including the identification and recruitment of nominees for election as a director of the Company.  The board believes that a nominating committee separate from the whole board is not necessary at this time to ensure that candidates are appropriately evaluated and selected, given the size of the Company and the board.  The board also believes that, given the Company’s size and the size of its board, an additional committee of the board would not add to the effectiveness of the evaluation and nomination process.  For these reasons, the board believes it is not appropriate to have a nominating committee.  

Three of the five members of the board, Messrs. Anderson, Zinnecker and Ms. Wilhelm are “independent” as that term is defined by The Nasdaq Marketplace Rules and the rules of the Securities and Exchange Commission.  These independent directors participate in the consideration of director nominees and select the nominees for election of director.  The independent directors unanimously selected and recommended the director nominee for election at this 2006 Annual Meeting of Shareholders, except that Ms. Wilhelm abstained with respect to the recommendation of her own nomination.

8

The board’s process for recruiting and selecting nominees is for board members to attempt to identify individuals who are thought to have the business background and experience, industry specific knowledge and general reputation and expertise that would allow them to contribute as an effective director to the Company’s governance, and who are willing to serve as a director of a public company.  Generally, the board will first consider current board members since they meet the criteria listed above and possess an in-depth knowledge of the Company, its history, strengths, weaknesses, goals and objectives.  This level of knowledge has proven very valuable to the Company.  Ms. Wilhelm, the nominee for election as a director at this 2006 Annual Meeting of Shareholders, was elected by the Company’s shareholders at the 2003 Annual Meeting of Shareholders.  To date, the Company has not engaged any third party to assist in identifying or evaluating potential nominees.  

After a possible candidate is identified, the individual meets with various members of the board to discuss their possible interest and willingness to serve, and board members discuss amongst themselves the individual’s potential to be an effective board member.  If the discussions and evaluation are positive, the individual is invited to serve on the board.

The board will consider shareholder recommendations for candidates to serve on the board and would evaluate any shareholder recommended nominee using the same process as applied to any other candidate.  In evaluating candidates, the board will require that candidates possess, at a minimum, a desire to serve on the Company’s board, an ability to contribute to the effectiveness of the board, an understanding of the function of the board of a public company and relevant industry knowledge and experience.  In addition, while not required of any one candidate, the board would consider favorably experience, education, training or other expertise in business or financial matters and prior experience serving on boards of public companies.  Collectively, the composition of the board must allow the Company to meet the listing standards of The Nasdaq Stock Market.  In evaluating any candidate for direct or nominee, the board will also evaluate the contribution of the proposed nominee toward compliance with The Nasdaq Stock Market listing standards.

Any shareholder who desires to communicate directly with the board of directors of the Company may address correspondence to the whole board, or any particular member of the board, in care of the Corporate Secretary at the Company’s offices:  10275 Wayzata Boulevard South, Suite 310, Minnetonka, Minnesota 55305.  All communications delivered in this manner will be promptly forwarded to the specified addressee, without alteration.

CODE OF ETHICS AND CODE OF CONDUCT

The Company has adopted a code of ethics relating to financial reporting that applies to its principal executive officer, principal financial officer, principal accounting officer and controller and other persons performing similar functions.  This code of ethics is included in the Company’s Code of Ethics filed as Exhibit 14.1 to the Company’s Annual Report on Form 10-KSB for the fiscal year ended September 30, 2003 filed with the Securities and Exchange Commission.  

The Company has also adopted a code of business conduct applicable to each of its directors, officers and employees to promote the ethical handling of conflicts of interest, full and fair disclosure, and compliance with laws, rules and regulations.  This code of conduct is available on the Company’s website at www.stencorporation.com.

REPORT OF THE AUDIT COMMITTEE

The Audit Committee consists of Allan D. Anderson (Chair), Gervaise Wilhelm and Jeffrey A. Zinnecker.  In accordance with its charter, the Audit Committee reviewed and discussed the audited consolidated financial statements with management and Virchow, Krause & Company, LLP.  Management represented to the Audit Committee that the Company’s consolidated financial statements were prepared in accordance with accounting principles generally accepted in the United States of America, and the Audit Committee has reviewed and discussed the consolidated financial statements with management and the independent accountants.  The discussions with Virchow, Krause & Company, LLP also included the matters required by Statement on Auditing Standards No. 61 (Communication with Audit Committees).

Virchow, Krause & Company, LLP provided to the Audit Committee the written disclosures and the letter regarding its independence as required by Independence Standards Board Standard No. 1 (Independence Discussions with Audit Committees).  This information was discussed with Virchow, Krause & Company, LLP.

Based on the discussions with management and Virchow, Krause & Company, LLP, the Audit Committee’s review of the representations of management and the report of Virchow, Krause & Company, LLP, the Audit Committee recommended to the board that the audited consolidated financial statements be included in the Company’s Annual Report on Form 10-KSB for the year ended September 30, 2005 filed with the Securities and Exchange Commission.

Employment Agreements

The Company does not have a written employment agreement with Kenneth W.

Director Compensation

The Company has historically paid its non-employee directors a fee of $1,000 per quarter.  The board, in its discretion, accepted no cash during fiscal year 2004 or 2003.  In November 2004, the Company paid each of Messrs. Anderson and Zinnecker and Ms. Wilhelm, the Company’s independent directors, $4,000 representing compensation of $1,000 per quarter for service in each of the four quarters in calendar year ending December 31, 2004.  In November 2005, the Company paid each of these independent directors $4,000 representing compensation of $1,000 per quarter for each of the four quarters in calendar year ending December 31, 2005.

The Company also typically grants each board member an option to purchase its common stock for service in the fiscal year.  On November 28, 2005, each of Messrs. Anderson and Zinnecker and Ms. Wilhelm received a five-year option to purchase 2,500 shares of the Company’s common stock for board service in fiscal year 2005.  These options were granted under the Company’s 2000 Stock Option Plan.  The exercise price of these options is $6.00 per share which was in excess of  the fair market value of the Company’s common stock on the date of grant and the options are fully vested and exercisable as of the date of grant.

Brimmer, the Company’s Chief Executive Officer and a director, and Gary Copperud, a director of the Company and an officer of BTAC.  In exchange for these guaranties, the Company’s Audit Committee approved a grant on December 11, 2003 to each of Mr. Brimmer and Mr. Copperud of a five-year non-qualified option to purchase 50,000 shares of the Company’s common stock from the Company’s 2000 Stock Option Plan.  The exercise price of these options is $6.00 per share, which was in excess of the fair market value of the Company’s common stock on the date of grant.  The Company’s Audit Committee approved the option and the guaranties by Messrs. Brimmer and Copperud.  The obligations guaranteed by Messrs. Brimmer and Copperud were satisfied by the Company in November 2004.
