Effective with Amendment No. 1 to MOU (defined in Item 6 herein), Vector is no longer a member of a “group”, but Vector does retain certain overbid protection rights as described in Item 6 herein.

This Amendment No. 13 (“Amendment No. 13”) amends and supplements the Schedule 13D, dated March 3, 2006 (the “Original Schedule 13D”), and filed by Steven G.

Effective with Amendment No. 1 to MOU (defined in Item 6 herein), Vector is no longer a member of a “group”. As such, this Amendment No. 13, with the exception of the information in Item 3, Item 4 under the heading “Amendment to MOU”, Item 5 and Item 6, is filed solely with respect to Mr. Mihaylo’s beneficial ownership of Common Stock of the Company.

Item 4.

Purpose of Transaction.

The response to Item 4 of the Schedule 13D is hereby amended and supplemented by adding the following paragraphs at the end of such Item 4:

Correspondence Regarding Mihaylo Ideas

On January 19, 2007, Mr. Mihaylo sent a letter (the “January 19 Letter”) to the Inter-Tel Board expressing his hope that, through a cooperative process with the Inter-Tel Board, Mr. Mihaylo and the Inter-Tel Board could develop a judicious plan of action to lead the Company forward with a renewed focus on enhancing stockholder value in the near and longer term. To that end, Mr. Mihaylo set forth a number of ideas for the Inter-Tel Board to consider implementing which Mr. Mihaylo believed would enhance value for all stockholders. Mr. Mihaylo stated in the January 19 Letter that he believed his ideas would benefit all of the Company’s stockholders by significantly increasing earnings per share and considerably reducing the friction between the current Inter-Tel Board and Mr. Mihaylo. Mr. Mihaylo further stated that he believed that if his ideas were implemented, another proxy contest could be averted, thus allowing the Inter-Tel Board to focus on the immediate task at hand of increasing stockholder value and growing the strongest possible Company for all stockholders. A copy of the January 19 Letter is filed as Exhibit 36 hereto and is incorporated herein by this reference.

On January 22, 2007, Mr. Mihaylo received a letter dated as of the same date from Mr. Cappello and Mr. Stout (the “Response Letter”) expressing appreciation for the constructive tone of Mr. Mihaylo’s January 19 Letter, and indicating that Mr. Cappello and Mr. Stout would contact Mr. Mihaylo shortly to arrange a convenient time to discuss the ideas raised in Mr. Mihaylo’s January 19 Letter, as well as some other thoughts Mr. Cappello and Mr. Stout had. Mr. Cappello and Mr. Stout also stated in the Response Letter that Mr. Mihaylo’s ideas were “both constructive and interesting.” A copy of the Response Letter is filed as Exhibit 37 hereto and is incorporated herein by this reference.

Following Mr. Mihaylo’s receipt of the Response Letter and through the date of this Amendment No. 13, representatives of Mr. Mihaylo held discussions with representatives of the Inter-Tel Board in an attempt to resolve the differences between Mr. Mihaylo and the Inter-Tel Board and avoid a proxy contest. Mr. Mihaylo also had meetings with Mr. Stout and Mr. Cappello for the same purpose. These discussions were unsuccessful.

Amendment to MOU

The information set forth in Item 6 of this Amendment No. 13 is hereby incorporated by reference herein.

Advance Notice

On March 2, 2007, in accordance with the advance notice by-law provisions contained in the Amended and Restated By-laws of the Company, Mr. Mihaylo delivered to the Company an advance notice of business to be brought before the 2007 Annual Meeting of Stockholders, the text of which follows:

March 2, 2007

By Hand

Inter-Tel (Delaware), Incorporated

1615 S. 52nd Street

Tempe, Arizona 85281

Attention: Secretary

Re:

Advance Notice of Stockholder Business

Ladies and Gentlemen:

I continue to believe that the Board (the “Board”) of Inter-Tel (Delaware), Incorporated (“Inter-Tel” or the “Company”) has failed to take steps that will maximize value for the Company’s stockholders. While I hoped that following the Special Meeting of Stockholders held in October (the “Special Meeting”) the Board would focus on its responsibility to maximize value for all stockholders, I believe that the Company’s current analysis of strategic alternatives has hit a dead-end that will result in stagnancy for the Company, and disappointment for its most important constituency, its stockholders.

In consideration of the foregoing, I hereby provide notice to the Secretary of the Company of business to be brought before the 2007 annual meeting of stockholders of the Company (the “2007 Annual Meeting”), in accordance with Section 2.12 of the By-laws of the Company (the “By-laws”).

I am the holder of record of 144,000 shares of common stock of the Company (the “Common Stock”) entitled to vote at the 2007 Annual Meeting. I am also the holder of record of options to acquire 7,500 shares of Common Stock of the Company with an exercise price of $21.11 and which became exercisable on November 12, 2006, and options to acquire 2,750 shares of Common Stock of the Company with an exercise price of $20.95 per share and which became exercisable on December 7, 2006. My business and record address is P.O. Box 19790, Reno, Nevada 89511. In addition, I am the sole trustee of The Steven G. Mihaylo Trust (the “Trust”) and, as such, may be deemed to be the beneficial owner of the

5,035,498 shares of Common Stock held by the Trust and entitled to vote at the 2007 Annual Meeting.¹

I intend to appear in person or by proxy at the 2007 Annual Meeting to introduce the resolutions set forth in this notice:

1. RESOLVED, that the stockholders of Inter-Tel (Delaware), Incorporated (“Inter-Tel”) recommend that the Inter-Tel Board of Directors (the “Board”) reduce the size of Inter-Tel’s Board from 11 to 7 members.

The reasons for proposal 1 (the “Board Reduction Resolution”) are to decrease expenses to the Company associated with directors’ fees, and to facilitate the scheduling of Board meetings. Recently, the Board has experienced great difficulty coordinating the schedules of 11 individuals with respect to organizing Board meetings. A Board consisting of 7 members will facilitate the scheduling of Board meetings while preserving the breadth of experience and backgrounds among Board members to successfully guide the Company.

Please note that concurrently herewith and in a separate letter dated as of the date hereof, I am submitting advance notice of 5 director nominations with respect to the 2007 Annual Meeting. If the Board agrees to reduce the size of the Board to 7 members, I would agree to remove 2 of my director nominees.

2. RESOLVED, that the stockholders of Inter-Tel (Delaware), Incorporated (“Inter-Tel”) recommend that the Inter-Tel Board of Directors (the “Board”) retain a financial advisor to advise the Board on the feasibility and financial impact of a Dutch-auction self tender offer to repurchase between $200 million and $250 million of Inter-Tel’s common stock.

The reasons for proposal 2 (the “Self Tender Offer Resolution”) are to distribute cash to the Company’s stockholders at a premium to current market prices, and to increase the earnings per share with respect to those shares that are not tendered.

3. RESOLVED, that the stockholders of Inter-Tel (Delaware), Incorporated (“Inter-Tel”) recommend that the Inter-Tel Board of Directors (the “Board”) disband the Special Committee of the Board.

4. RESOLVED, that the stockholders of Inter-Tel (Delaware), Incorporated (“Inter-Tel”) recommend that the Inter-Tel Board of Directors (the “Board”) direct

______________________

¹While Vector Capital Corporation (“Vector”) has previously filed Schedule 13Ds with the Securities and Exchange Commission as a member of a “group” with me, Vector disclaimed beneficial ownership of the shares of Common Stock beneficially owned by me. As of the date of this letter, Vector and I have terminated the Memorandum of Understanding among myself, Summit Growth Management LLC (an affiliate of mine) and Vector with regards to the shares of Common Stock of the Company, dated May 18, 2006, and Vector is no longer a member of a “group.”

Inter-Tel’s management to (a) undertake an intensive cost-benefit analysis of (i) discontinuing product development on the Axxess and (ii) redirecting the engineering effort to “gateway” products and “hosted services” offerings, including the necessary billing platform for hosted services, and (b) report the results of that analysis to the Board.

5. RESOLVED, that the stockholders of Inter-Tel (Delaware), Incorporated (“Inter-Tel”) recommend that the Inter-Tel Board of Directors consolidate Inter-Tel’s multiple engineering facilities into the Chandler, Arizona location.

6. RESOLVED, that the stockholders of Inter-Tel (Delaware), Incorporated (“Inter-Tel”) recommend that the Inter-Tel Board of Directors explore the sale of Inter-Tel’s Irish subsidiary.

7. RESOLVED, that the stockholders of Inter-Tel (Delaware), Incorporated (“Inter-Tel”) recommend that the Inter-Tel Board of Directors explore ways to better utilize Inter-Tel’s 15 acre campus in Reno, Nevada.

The reason for proposals 3 through 7 (collectively, the “Stockholder Value Resolutions”) is to provide a clear path for the Company to follow in pursuit of enhanced stockholder value. I believe the ideas set forth in the Stockholder Value Resolutions will enable to the Company to increase stockholder value by accomplishing, among other things, the following goals:

•

reduce overhead and other expenses;

•

efficiently utilize existing resources;

•

refocus on the Company’s strengths;

•

improve productivity and utilization;

•

stimulate and foster creativity;

•

improve product and service revenue growth; and

•

align the Company’s current resources with its future product strategy.

The effectiveness of each of the proposals set forth in this notice is not conditioned upon the approval of any other proposal. I intend to deliver a proxy statement and form of proxy to holders of at least the percentage of the Company’s voting shares required under Delaware law to carry each of the proposals set forth in this notice.

On April 21, 2006, Summit Growth Management LLC (“Summit”), an entity through which I make investments and of which I am the sole member and managing member, and I filed a preliminary proxy statement with the SEC in

connection with the 2006 Annual Meeting of shareholders of the Company (the “2006 Annual Meeting”) relating to a number of proposals, including the election of three directors. On May 5, 2006, Summit and I entered into a settlement agreement with the Company (the “Settlement Agreement”) to settle the potential proxy context in connection with the 2006 Annual Meeting. In addition to other provisions, the Settlement Agreement stipulated that the Company would appoint me, Dr. Puri and Mr. Urish to the Board and consider an offer to acquire the Company made by me meeting certain criteria. On June 14, 2006, Vector Capital Corporation (“Vector”) and I submitted a proposal to acquire all of the outstanding shares of Common Stock (other than shares beneficially owned by me) for $22.50 per share in cash (the “June 14 Proposal”). The Company raised various issues with respect to the June 14 Proposal, and on June 28, 2006, Summit and I entered into the Amendment to Settlement Agreement with the Company, which provided, among other things, that the Company would not respond to the June 14 Proposal, and extended the deadline for me to submit an offer. On July 28, 2006, Vector and I submitted a proposal to the Board to acquire all of the outstanding shares of Common Stock (other than shares beneficially owned by me) for $22.50 per share in cash (the “July 28 Proposal”). On August 11, 2006, the Special Committee of the Board (the “Special Committee”) rejected the July 28 Proposal. On August 21, 2006, in a letter to the Special Committee, Vector and I indicated a willingness to increase our offer price to $23.25 per share in cash (the “August 21 Indication”). On August 25, 2006, the Special Committee rejected the August 21 Indication, and pursuant to the Settlement Agreement, I submitted a request that the Company call a special meeting of stockholders (the “Special Meeting”) to consider the following proposal: “RESOLVED, that the stockholders of Inter-Tel (Delaware), Incorporated (“Inter-Tel”) urge the Inter-Tel Board of Directors to arrange for the prompt sale of Inter-Tel to the highest bidder” (the “Sell the Company Resolution”). At the Special Meeting, 11,272,464 shares were voted against the Sell the Company Resolution, representing slightly over 50% of the 22,524,535 shares of Common Stock of the Company that were represented in person or by proxy. On November 8, 2006, Vector and I withdrew our offer to acquire all of the outstanding shares of Common Stock of the Company. Based on my beneficial ownership of shares of Common Stock of the Company and the foregoing, I have a material interest in each of the resolutions that I am proposing for consideration by the stockholders at the 2007 Annual Meeting.

I am very concerned about reports I have received that there may have been ERISA violations in connection with the solicitation of proxies by management in connection with the Special Meeting. I expect that the Board and officers of Inter-Tel will take every precaution to abide by all applicable laws in its solicitation of proxies for the 2007 Annual Meeting and will not make any attempts to coerce or intimidate employees of Inter-Tel in the way they vote shares of Common Stock beneficially owned by them.

Also on March 2, 2007, in accordance with the advance notice by-law provisions contained in the Amended and Restated By-laws of the Company, Mr. Mihaylo delivered to the Company an advance notice of director nominations to be brought before the 2007 Annual Meeting of Stockholders, the text of which follows:

Re:

Advance Notice of Director Nominations

Ladies and Gentlemen:

In consideration of the foregoing, I hereby provide notice to the Secretary of the Company of nominations for the election of directors to be brought before the 2007 annual meeting of stockholders of the Company (the “Annual Meeting”), in accordance with Section 2.13 of the By-laws of the Company (the “By-laws”).

I am the holder of record of 144,000 shares of common stock of the Company (the “Common Stock”) entitled to vote at the Annual Meeting. I am also the holder of record of options to acquire 7,500 shares of Common Stock of the Company with an exercise price of $21.11 and which became exercisable on November 12, 2006, and options to acquire 2,750 shares of Common Stock of the Company with an exercise price of $20.95 per share and which became exercisable on December 7, 2006. My business and record address is P.O. Box 19790, Reno, Nevada 89511. In addition, I am the sole trustee of The Steven G. Mihaylo Trust (the “Trust”) and, as

such, may be deemed to be the beneficial owner of the 5,035,498 shares of Common Stock held by the Trust and entitled to vote at the Annual Meeting.¹

I hereby nominate the following individuals (the “Mihaylo Nominees”) for election as directors of the Company at the Annual Meeting:

I intend to appear in person or by proxy at the Annual Meeting to nominate the persons named in this notice.

The information regarding the individuals listed above required by Section 2.13 of the By-laws is set forth on Exhibit A and Exhibit C attached hereto. Also enclosed is the written consent of each individual listed above to being named as a nominee and to serve as a director if elected. Information regarding me required by Section 2.13 of the By-laws, in addition to that contained in this notice, Exhibit A and Exhibit C, is set forth on Exhibit B.

As required by Section 2.13(a) of the By-laws, Exhibit A contains the residence address of each of the nominees. I hereby request that the Company hold this information in confidence and not release it publicly because this information is not required by Schedule 14A promulgated by the Securities and Exchange Commission.

I intend to deliver a proxy statement and form of proxy to holders of at least the percentage of the Company’s voting shares required under Delaware law and the By-laws to elect the nominees. Based upon the number of shares that I beneficially own and cumulative voting under Article IV(C) of the Certificate of Incorporation of the Company, I should be able to elect at least two directors at the Annual Meeting.

Please note that concurrently herewith and in a separate letter dated as of the date hereof, I am submitting advance notice of stockholder business with respect to the Annual Meeting. One of the proposals contained in that notification involves a proposal for the Board to consider reducing the size of the Board from 11 to 7 members (the “Board Reduction Resolution”). I am not seeking to nominate individuals who, if elected, would constitute a majority of the Board. Therefore, if

While Vector Capital Corporation (“Vector”) has previously filed Schedule 13Ds with the Securities and Exchange Commission as a member of a “group” with me, Vector disclaimed beneficial ownership of the shares of Common Stock beneficially owned by me.

the Board Reduction Resolution is adopted by the stockholders and the Board determines to reduce the size of the Board to 7 directors, I would expect that the representation of the Mihaylo Nominees would be reduced in proportion to the reduction in size of the Board.

I am very concerned about reports I have received that there may have been ERISA violations in connection with the solicitation of proxies by management in connection with the Special Meeting. I expect that the Board and officers of Inter-Tel will take every precaution to abide by all applicable laws in its solicitation of proxies for the Annual Meeting and will not make any attempts to coerce or intimidate employees of Inter-Tel in the way they vote shares of Common Stock beneficially owned by them.

Mr. Mihaylo was initially approached by Dr. Puri, Dean of the College of Business and Economics and one of Mr. Mihaylo’s Board nominees, about making a donation to the College of Business and Economics. In 2005, California State University, Fullerton, conferred an honorary doctorate of humane letters upon Mr. Mihaylo in recognition of his significant contributions in areas of human endeavor. Mr. Mihaylo has been active in and supported education-related charitable endeavors during his career, including Junior Achievement of Arizona, Big Bear Lake California High School, the University of Arizona, Arizona State University, Bishop Manogue Catholic High School, the University of Nevada, Reno, The Arizona Science Center, Juvenile Diabetes Research Foundation, The Goldwater Institute and The Desert Botanical Gardens.

As to each person Mr. Mihaylo proposes to nominate for election as a director:

Each of the nominees has consented to be nominated by Mr. Mihaylo and to serve as a director if elected, and it is not contemplated that any of them will be unavailable for election as a director.

Other than as set forth in this Exhibit A, Exhibit B and Exhibit C and other than with respect to each nominee’s nomination as a director, and except for Mr. Mihaylo, none of the nominees nor any associate of any nominee has any substantial interest, direct or indirect, by security holdings or otherwise, in any matter to be acted upon at the 2007 Annual Meeting.

On April 21, 2006, Mr. Mihaylo and Summit Growth Management LLC (“Summit”), an entity through which Mr. Mihaylo makes investments and of which he is the sole member and managing member, filed a preliminary proxy statement with the SEC in connection with the 2006 Annual Meeting of shareholders relating to a number of proposals, including the election of three directors (Mr. Mihaylo, Dr.

Puri and Mr. Urish). On May 5, 2006, Mr. Mihaylo, Summit and the Company entered into a settlement agreement (the “Settlement Agreement”) to settle the potential proxy context in connection with the 2006 Annual Meeting. In addition to other provisions, the Settlement Agreement stipulated that the Company would appoint Mr. Mihaylo, Dr. Puri and Mr. Urish to the Board and consider an offer to acquire the Company by Mr. Mihaylo meeting certain criteria. On June 14, 2006, Mr. Mihaylo and Vector Capital Corporation (“Vector”) submitted a proposal to acquire all of the outstanding shares of Common Stock (other than shares beneficially owned by Mr. Mihaylo) for $22.50 per share in cash (the “June 14 Proposal”). The Company raised various issues with respect to the June 14 Proposal, and on June 28, 2006, Mr. Mihaylo, Summit and the Company entered into the Amendment to Settlement Agreement, which provided, among other things, that the Company would not respond to the June 14 Proposal, and extended the deadline for Mr. Mihaylo to submit an offer. On July 28, 2006, Mr. Mihaylo and Vector submitted a proposal to the Board to acquire all of the outstanding shares of Common Stock (other than shares beneficially owned by Mr. Mihaylo) for $22.50 per share in cash (the “July 28 Proposal”). On August 11, 2006, the Special Committee of the Board (the “Special Committee”) rejected the July 28 Proposal. On August 21, 2006, in a letter to the Special Committee, Mr. Mihaylo and Vector indicated a willingness to increase their offer price to $23.25 per share in cash (the “August 21 Indication”). On August 25, 2006, the Special Committee rejected the August 21 Indication, and pursuant to the Settlement Agreement, Mr. Mihaylo submitted a request that the Company call a special meeting of stockholders (the “Special Meeting”) to consider the following proposal: “RESOLVED, that the stockholders of Inter-Tel (Delaware), Incorporated (“Inter-Tel”) urge the Inter-Tel Board of Directors to arrange for the prompt sale of Inter-Tel to the highest bidder” (the “Sell the Company Resolution”). At the Special Meeting, 11,272,464 shares were voted against the Sell the Company Resolution, representing slightly over 50% of the 22,524,535 shares of the Company’s common stock that were represented in person or by proxy. On November 8, 2006, Mr. Mihaylo and Vector withdrew their offer to acquire all of the outstanding shares of Common Stock of the Company. Based on his beneficial ownership of shares of Common Stock of the Company and the foregoing, Mr. Mihaylo has a substantial interest in each of the nominations that he has proposed for consideration by the stockholders at the 2007 Annual Meeting.

The Trust is a participant in the solicitation and an “associate” of Mr. Mihaylo as such term is defined in Schedule 14A promulgated by the Securities and Exchange Commission under the Securities and Exchange Act of 1934 (“Schedule 14A”), as amended. Accordingly, as set forth in this Exhibit A, Exhibit B and Exhibit C and based upon the Trust’s ownership of Common Stock, the Trust could be deemed to have a substantial interest in each of the nominations Mr. Mihaylo has proposed for consideration by the stockholders at the 2007 Annual Meeting.

Summit is a participant in the solicitation and an “associate” of Mr. Mihaylo as such term is defined in Schedule 14A. Accordingly, as set forth in this Exhibit A, Exhibit B and Exhibit C, Summit could be deemed to have a substantial interest in

each of the nominations Mr. Mihaylo proposed for consideration by stockholders at the 2007 Annual Meeting.

Each of the nominees is a participant in the solicitation of proxies by Mr. Mihaylo.

During the Company’s last fiscal year, and except as otherwise set forth in this Exhibit A, Exhibit B or Exhibit C:

Other than as set forth in this Exhibit A, Exhibit B and Exhibit C, none of the participants owns of record, but not beneficially, any securities of the Company.

Other than as set forth in this Exhibit A, Exhibit B and Exhibit C, none of the participants has purchased or sold, within the past 2 years, any securities of the Company.

Other than as set forth in this Exhibit A, Exhibit B and Exhibit C, none of the participants is, or within the past year was, a party to any contract, arrangements or understandings with any person with respect to any securities of the Company, including, but not limited to, joint ventures, loan or option arrangements, puts or calls, guarantees against loss or guarantees of profit, division of losses or profits, or the giving or withholding of proxies.

No associate of any participant owns beneficially, directly or indirectly, any securities of the Company, other than the Trust.

None of the participants owns beneficially, directly or indirectly, any securities of any parent or subsidiary of the Company.

Since the beginning of the Company’s last fiscal year, none of the participants nor any immediate family member of any participant has a direct or indirect interest in any transaction or series of similar transactions, or any currently proposed transaction or series of similar transactions, to which the Company or any of its subsidiaries was or is to be a party, which involves an amount greater than $120,000. In addition, none of the participants nor any immediate family member of any participant has been indebted to the Company or any of its subsidiaries for over $120,000 at any time since the beginning of the last fiscal year. A summary of Mr. Mihaylo’s, Mr. Urish’s and Dr. Puri’s compensation is set forth on Exhibit C attached hereto.

Other than as set forth in this Exhibit A, Exhibit B and Exhibit C, none of the participants, nor any associate of any participant, has any arrangement or understanding with any person with respect to any future employment by the Company or its affiliates or with respect to any future transactions to which the Company or any of its affiliates will or may be a party.

Other than as set forth in this Exhibit A, Exhibit B and Exhibit C, none of the participants has held any position or office with the Company. In addition, other than their consent to be nominated to serve on the Board by Mr. Mihaylo and to serve if elected, none of the nominees is a party to any arrangement or understanding between such nominee and any other person(s) pursuant to which he was or is to be selected as a director or nominee.

None of the participants has, during the past 10 years, been convicted in a criminal proceeding or is a named subject of a pending criminal proceeding (excluding traffic violations and other minor offenses).

There are no family relationships between any director or executive officer of the Company, on the one hand, and the nominees on the other hand, or between any of the nominees.

With respect to each nominee, during the past five years, none of the events described in Item 401(f) of Regulation S-K occurred with respect to such nominee that is material to any evaluation of the ability or integrity of any such nominee to become a director of the Company.

Other than certain stockholder litigation of which the Company is aware, there are no material pending legal proceedings, other than ordinary routine litigation incidental to the business, to which any nominee or any associate of any nominee is a party adverse to the Company or any of its subsidiaries or has a material interest adverse to the Company or any of its subsidiaries.

None of the nominees will receive any compensation from Mr. Mihaylo for his service as a nominee for election or as a director, if elected, of the Company. If elected as directors, it is anticipated that the nominees may receive director fees from the Company and participate in the Company’s benefit plans for directors, all as determined by the Company.

Other than as set forth in this Exhibit A, Exhibit B and Exhibit C, none of the nominees has had any relationship with the Company in any capacity other than as stockholder.

On May 18, 2006, Mr. Mihaylo, Summit and Vector Capital Corporation (“Vector”) entered into a Memorandum of Understanding (the “Memorandum”) with respect to the potential acquisition of the Company.

Company, Mr. Mihaylo chooses to sell or vote his shares of Common Stock, within 12 months of the termination of the Memorandum, in favor of another change of control transaction, Mr. Mihaylo/Summit would pay to Vector, either in cash or in the form of consideration received by Mr. Mihaylo for his shares of Common Stock in such transaction, a specified amount as “overbid protection” in accordance with the formula set forth in the Memorandum.

Such services may include assisting Mr. Mihaylo in structuring, negotiating, implementing and coordinating key aspects of a possible Transaction (as defined below) and in the solicitation of parties interested in providing equity and/or debt financing in connection with a possible Transaction. “Transaction” means any transaction or series or combination of related transactions, whereby directly or indirectly, a majority of the capital stock of the Company is, or assets representing a majority in value of the assets of the Company are, transferred to Mr. Mihaylo or otherwise becomes beneficially owned by Mr. Mihaylo for consideration, including, without limitation, a sale or exchange of capital stock (including by means of a tender offer) or assets, a merger, plan of exchange or consolidation, the formation of a joint venture, a minority investment or partnership, or any similar transaction.

As compensation for its services under the RBC Agreement, RBC has received a non-refundable cash retainer fee, and is entitled to receive (i) an agreed upon transaction fee in the event that Mr. Mihaylo consummates, during the term of the RBC Agreement or during the 12 months following the term, a Transaction pursuant to a definitive agreement, letter of intent or other evidence of a commitment entered into between Mr. Mihaylo and the Company, or by means of a tender offer to the stockholders of the Company initiated by Mr. Mihaylo, and (ii) an agreed upon topping fee in the event that a Third Party Transaction (as defined below) is consummated during the term of the RBC Agreement or during the 12 months following the term and such Third Party Transaction is subsequent to any offer (whether written or oral) made by Mr. Mihaylo to the Company relating to a Transaction. On June 14, 2006, Mr. Mihaylo and Vector submitted such an offer to the Company. “Third Party Transaction” means any transaction or series or combination of related transactions, whereby directly or indirectly, a majority of the capital stock of the Company is, or assets representing a majority of the assets of the Company are, transferred to a person not affiliated with Mr. Mihaylo or the Company for consideration, including, without limitation, a sale or exchange of capital stock or assets, a merger, plan of exchange or consolidation, the formation of

a joint venture, a minority investment or partnership, or any similar transaction. In addition, RBC will be reimbursed for its reasonable out of pocket expenses in performing the services under the RBC Agreement, up to an agreed upon dollar amount. The term of the RBC Agreement is one year, unless earlier terminated by one or both parties upon 30 days written notice to the other.

Banks, brokers, custodians, nominees and fiduciaries will be requested to forward solicitation material to beneficial owners of Common Stock. Mr. Mihaylo will reimburse banks, brokers, custodians, nominees and fiduciaries for their reasonable expenses for sending solicitation material to the beneficial owners.

The total amount to be spent on the solicitation is estimated to be $500,000. To date, approximately $50,000 has been expended in connection with the solicitation.

The cost of the solicitation will be borne by Mr. Mihaylo, and, if successful, Mr. Mihaylo will seek reimbursement of these costs from the Company. The question of such reimbursement will not be submitted to a vote by the stockholders of the Company.
