The Updated Disclosure Schedules only update the Disclosure Schedules furnished to the Purchasers on March 8, 2006 as updated on September 26, 2006, and do not restate the disclosures set forth therein in their entirety.

Each Section below qualifies the correspondingly numbered section or subsection thereof in Article IV of the Amended Note Purchase Agreement, as applicable. Terms of documents summarized herein are qualified in their entirety by the documents themselves, provided that nothing is misleading in such summaries. The titles and headings used herein are for reference purposes only and shall not in any manner limit the construction of these Schedules, and any disclosure made under any subheading hereunder is deemed made for all provisions of that corresponding section in the Amended Note Purchase Agreement.

Section 2.02

Authorization of Agreements, Etc.

(a) Section 2.2 of that certain Security and Pledge Agreement, dated March 8, 2006, as amended, by and among the Company, DSI, Lloyd I. Miller, III, and SACC Partners, L.P. (the “Senior Security Agreement”), as well as Section 2.2 of that certain Security and Pledge Agreement, dated March 8, 2006, as amended, by and among the Company, DSI, and Trust A-4 — Lloyd I.

Section 2.08

Material Changes

(iii) (1) On October 6, 2006, the Company entered into an Asset Purchase Agreement for substantially all of the assets of TekConnect, Inc. In consideration for the purchased assets, the Company paid to sellers $400,000 at closing, incurred $63,000 of direct acquisition costs and assumed $540,000 pre-existing contract obligations.

(2) On October 27, 2006, the Company, DynTek Canada, an Ontario corporation and wholly-owned subsidiary of the Company, Sensible Security Solutions, Inc., an Ontario corporation (“SSS”), and Paul Saucier, an individual and 100% owner of SSS, entered into an asset purchase agreement for the acquisition by DynTek Canada of substantially all of the assets of SSS. In consideration of the purchased assets, we paid SSS at closing a cash payment of $1.1 million, and also issued 1,485,148 shares of our Common Stock to SSS with an aggregate fair value of $300,000. The Company is obligated to make additional payments of up to $4.7 million over a three-year period based upon the achievement of certain EBITDA performance targets.

(3) On September 26, 2006, the Company entered into a Second Amendment to Note Purchase Agreement (the “Second Amendment”), pursuant to which the Company issued to Trust A-4 — Lloyd I. Miller a Junior Secured Convertible Note in the aggregate principal amount of $3,000,000 (the “Third Junior Note”). In January of 2007, the Company received a comment letter on a Registration Statement on Form S-1 indicating that the Company may have violated Section 5 of the Securities Act in connection with its issuance of the Third Junior Note. An investor’s remedy for violations of Section 5 of the Securities Act could include making a demand for a rescission of the investment. While the Company believes that its issuance of these securities was in compliance with Section 5 and any other applicable regulations, it nonetheless requested and received from each of Lloyd I. Miller, III, SACC Partners, L.P. and Trust A-4 — Lloyd I. Miller waivers and releases of any rescission rights in connection with any such potential Section 5 violation. The Company obtained such waivers on February 2, 2007.

(4) On March 28, 2007, the Company entered into a Business Lease Agreement with Hewlett-Packard Financial Services Company, pursuant to which the Company has agreed to lease certain equipment set forth on Annex I thereto. The monthly lease payment is $951.76 and the term of the lease is 36 months.

(iv) (1) In connection with the transactions contemplated by the Amended Note Purchase Agreement, DynTek has agreed to pledge 66.0% of the stock of DynTek Canada, Inc., a wholly-owned subsidiary of DynTek.

Section 2.09

Litigation

(1) On or about July 19, 2006, Pangaea Education Systems, LLC (“Pangaea”) filed a lawsuit in District Court for the Middle District of Florida against DSI alleging unfair competition, reverse passing off, misappropriation of trade secrets, copyright infringement and breach of contract arising out of services performed in 2003. On September 11, 2007 the Company entered into a settlement agreement with Pangaea and in exchange for a complete release from any further liability, the Company agreed to pay $47,500 to Pangaea.

(2) On March 6, 2007, the Company was served with a subpoena to produce certain enumerated business records regarding the Company’s contractual relationship with the New York City Department of Education. The Company has complied with this subpoena and produced responsive documents on April 2, 2007. The New York City Department of Education is conducting an investigation of the computer consulting services provided by the Company to determine whether such services were provided in conformity with the contractual prohibition against the Company contracting with a subcontractor to perform such consulting work for the New York City Department of Education. Based on its contract with the New York City Department of Education and the parties’ custom and practice, the Company believes it has acted in accordance with its contract with the New York City Department of Education. However, an ambiguity exists as to the meaning of the term “subcontractor,” which may result in a finding that there has been work contracted with the Company that was performed by a “subcontractor.” In light of the ambiguity of the term “subcontractor” and the parties’ custom and practice, such a finding does not necessarily mean that the Company has breached its contract with the New York City Department of Education. To date, no suit has arisen from the New York City Department of Education’s investigation and no monetary demands have yet been made.
