                              Employment Agreement
                             G. Dennis Key, Employee

This Employment Agreement ("Agreement") is made effective as of July 1, 2003, by
and between Aspect Systems, Inc. ("Company"), and G. Dennis Key ("Employee").
Employee hereby represents that no restrictions exist prohibiting him from
executing and performing this Agreement.

WHEREAS, Company wishes to employ Employee under the terms and conditions set
forth below. And Employee wishes to accept such employment under the terms and
conditions set forth below;

WHEREAS, Employee acknowledges that Employee has read and is fully familiar with
the terms of this Agreement, that Employee has had a reasonable opportunity to
consider this Agreement and to seek legal counsel, and that after such review,
Employee finds that the promises and considerations provided by Employee in this
Agreement are not greater than necessary for the protection of Company's good
will and legitimate business interests and do not create undue hardship for
Employee or the public;

NOW, THEREFORE, the parties agree as follows:

1. Position. Employee shall hold the position as "President" of the Company. As
of January 1, 2004, Employee shall also hold the position of CEO of the Company.
Douglas N. Dixon ("Chairman") shall remain Chairman of the Board of the Company.

2. Board Member. During the Term hereof, Employee shall be appointed as a
Director to the Board of Directors of the Company and Employee shall be
appointed as a Director of the Board of Directors of DNDT.

3. Financial Matters. During the Term hereof, Chairman and Employee agree that
on any significant financial matters concerning the Company or DNDT, the parent
company of the Company, where Chairman and Employee do not agree on the spending
or financial matter to be taken, then such matters shall be taken to the
appropriate Boards of the Company and/or DNDT for discussion and approval. For
these purposes Employee shall have an opportunity to voice his concerns over any
such matters with the Boards of DNDT and/or the Company, whichever are
applicable.

4. Duties. Employee will perform the duties of the position to which he is
assigned in a reasonable, timely and professional manner, and shall comply with
all applicable policies and rules of Company. When company finances allow for
Employee's return to full salary, and when the cost of relocation will not
create an unnecessary burden for the Company, Employee shall move from Texas to
Arizona. Until that time, Employee shall make a best effort to spend two out of
every three weeks at the Company headquarters in Chandler.

<PAGE>

5. Term and Termination. Company agrees to employ Employee for a period not less
than two years from the date hereof. Employee and Company may terminate this
Agreement only for "cause" as defined in this Agreement. Employee may terminate
employment with "cause", at any time, upon thirty days notice to the Company.
This notice requirement is intended to help the Company protect its business
interests, preserve customer good will, and facilitates the transfer of
information that is necessary for the Company to maintain its competitive
advantage. Company may terminate Employee's employment with "cause", upon
fourteen days notice. Company may, at its option, provide pay in lieu of notice
and upon doing so will have no further payment obligations to Employee except as
set forth herein. For "cause" is defined below.

      A. For Cause. Notwithstanding any other provision of this Agreement, the
Employee's employment, and all Employee's rights and benefits under this
Agreement, may, at the discretion of the Chairman or by the majority vote of the
Board of Directors of the Company, be terminated immediately and without further
notice and without liability to the Company upon the happening of any one or
more of the following events:

            (1). If the Employee is convicted of any of the following: (i) any
            felony, (ii) any misdemeanor in the nature of fraud, theft or
            conversion of property, or (iii) any offense involving moral
            turpitude which, in the sole and unfettered discretion of the
            Chairman, has or could have an adverse effect on the business or
            reputation of the Company, or (iv) any offense involving the use,
            possession, or distribution of any illicit drug or other controlled
            substance;

            (2). If the Employee exhibits any conduct, including:

                  (a). chronic or repeated unexcused absence, which adversely or
                  materially affects the performance of his duties;

                  (b). negligence or dereliction of duty, which materially
                  interferes with the performance of his duties;

                  (c). insubordination; or

                  (d). a pattern of inappropriate behavior, which negatively
                  affects or has the substantial potential to materially and
                  adversely affect the Company, as reasonably determined by the
                  Chairman or by the Directors by majority vote to be in
                  violation of his duties to the Company. If the Company
                  provides Employee written notice of any conduct which the
                  Company finds objectionable, and if the Employee persists in
                  or repeats such similar conduct or does not remedy the
                  identified deficiency in his performance within a reasonable
                  time following such notice, the same shall be deemed
                  conclusively to establish the Company' right to terminate the
                  Employee pursuant to this subsection. However, prior written
                  notice shall not be required prior to termination under this
                  section.

                                       2

                  (3). If the Chairman or the Board of Directors by majority
                  vote in good faith determines that the Employee willfully
                  provided false or misleading information to the Company,
                  either prior to or during employment, or breached his
                  fiduciary duties to the Company, or committed fraud, theft or
                  conversion of Company property, or has engaged in other
                  unlawful conduct, including but not limited to the use or
                  possession of illicit drugs or any other controlled
                  substances, (other than medications prescribed by a physician)
                  or the use of alcohol during working hours or on Company
                  premises, except (with respect to alcohol) use in the ordinary
                  course of business, regardless whether any civil or criminal
                  action is brought against the Employee;

                  (4). If the Employee refuses to submit to any scheduled or
                  random periodic test, search, and/or investigation as may be
                  required by the Company from time-to-time as part of any
                  program implemented by the Company generally applicable to its
                  employees to detect the use, presence or possession of illicit
                  drugs or any other controlled substances.

      B. Resignation. In the event the Employee wishes to resign his employment,
      the Employee shall notify the Company of his intent to resign 60 days in
      advance of his intended last day of employment. Employee agrees to
      cooperate in the Company's efforts to locate and train a replacement
      employee. Employee agrees to continue to perform his employment duties and
      responsibilities as outlined in Paragraph 3, above, and as may be
      contained in a written Job Description that may be provided by the
      Chairman to Employee from time to time, during the period between giving
      his notice of resignation and his last day of work. In the event of
      resignation by Employee during the term hereof, Employee shall be entitled
      to severance compensation equal to two months salary and two months of
      benefits.

      Agreement, the terns "disability" means the continuous and uninterrupted
      inability of Employee to perform his duties by reason of accident or
      physical or mental illness or disease for a period of 60 days. During the

      termination of this Agreement by the Company as a result of such
      disability, as hereinafter provided, all salary and fringe benefits
      provided under this Agreement shall continue except that the salary shall
      be reduced by the amount of benefits received by Employee pursuant to any
      disability insurance policy or policies, if any, procured by the Company
      for the Employee's benefit.

            In the event the disability ceases within one year from the start
      date of disability, Employee has the option of resuming his position for
      the remainder of the original Term hereof, provided that Employee is able
      to discharge the duties of Employee's position. During the term of
      disability Employee shall remain an officer of the Company.

            In the event of Employee's death during the term hereof, the
      Employee shall be paid two years salary. The Company shall purchase term
      life insurance for Employee and for the Chairman, who has this same
      benefit, to cover this payment. Death during the

                                       3
<PAGE>

      Term hereof shall terminate Employee's obligations to discharge his
      position, however, this Agreement shall remain in full force and effect to
      discharge any remaining obligations due hereunder.

            The Company may terminate this Agreement in the event Employee
      elects to not resume his position after the one year period or if Employee
      is unable to discharge the duties of his position after such one year
      period.

all documents necessary to confirm or perfect the exclusive ownership of Company
to the Work Product.

8. Confidentiality.

      A. Definitions. As used herein "Trade Secrets" are information of special
      value, not generally known to the public or competitors, that the Company
      has taken steps to maintain as secret from persons other than those
      selected by the Company. "Confidential Information" is information
      acquired by Employee in the course and scope of his or her

                                       4
<PAGE>

      activities for Company that is designated by Company as confidential, or
      that Company indicates through its policies, procedures or other
      instructions should riot be disclosed to anyone outside Company except
      through controlled means. The controlled disclosure of Confidential
      Information to customers, business associates or vendors for legitimate
      business purposes and the availability of the Confidential Information to
      others outside Company, through independent investigation and effort, will
      not remove it from protected status as Confidential Information under this
      agreement if Employee was first entrusted with the Confidential
      Information in confidence while working on behalf of Company. Confidential
      Information and/or Trade Secrets are generally referred to herein as
      "Proprietary Information." Without limitation, some examples of protected
      Proprietary Information are Company's manufacturing processes, engineering
      or design specifications, marketing and research information, personnel
      evaluations, customer lists, supplier lists, new product development
      plans, pricing and cost information, business plans and marketing plans or
      strategies. Proprietary Information may be both a Trade Secret and
      Confidential Information, but need not be both to be protected hereunder.

      B. Company Covenants. Upon execution of this Agreement, Employee has been
      given access to Proprietary Information of the Company through computer
      password access and physical access to purchase orders, sales orders, work
      instructions, pricing information, drawings, customer lists, customer
      contacts, vendor information and company policies and procedures. Within
      90 days from the effective date of this Agreement, and as deemed necessary
      by Company thereafter, Company will do one or more of the following: (a)
      provide Employee with Proprietary Information of the Company, or access to
      such information; or (b) provide Employee with goodwill support such as
      expense reimbursements in accordance with Company policy limits, access to
      Proprietary Information, and/or facilitate contact with customers and
      prospective customers in order to help Employee develop goodwill for
      Company. The foregoing is not conditioned upon Employee's continued
      service to Company, but it is conditioned upon complete compliance with
      all of the restrictions and promises contained in this Agreement.

      C. Employee Covenants. Employee agrees not to disclose any of the
      Company's Proprietary Information, directly or indirectly, to any
      unauthorized person, and not to use it in any way, either during the term
      of this agreement or at any time thereafter, except as required for the
      benefit of Company or as compelled by law (such as subpoena or court
      order). Employee also agrees to use the goodwill and contacts developed
      with Company's customers and contractors for the exclusive benefit of
      Company, and agrees not to use these items in a way that would harm the
      business interests of the Company while subject to any part of this
      Agreement. Employee will not at any time, or in any manner, either
      directly or indirectly, use for personal benefit of Employee, or divulge,
      disclose or communicate in any manner any information that is proprietary
      to Company. Employee will protect such information and treat it as
      strictly confidential. This provision shall continue to be effective after
      the termination of this Agreement. Employee will return to Company all
      records, notes, documentation and other items that were used, created or
      controlled by Employee during the term of this Agreement.

                                       5
<PAGE>

      D. Other Covenants. Company hereby agrees that as consideration for
      Employee's promises herein, Employee will be eligible for Company's Paid
      Time off (for Vacation, Illness and Personal Floating Holidays), Bonus
      Plan, 401k Savings Plan, and Long Term Disability, subject to the terms
      and conditions of each specific benefit program (as it may be amended from
      time to time) and the terms of this Agreement. Employee shall be provided
      with travel related life insurance for accidental death in the amount of
      $1,000,000. In exchange for the foregoing and the additional terms agreed
      to in this Agreement, if Employee is an existing employee of Company,
      Employee agrees (a) that this Agreement will replace any existing (a)
      employment agreement covering the same subjects, if any, between the
      parties and thereby acts as a novation, and (b) that all Company
      Proprietary Information developed or received by Employee during past
      employment with Company and all goodwill developed with the Company's
      clients, customers and other business contacts by Employee during past
      employment with Company is now the exclusive property of the Company and
      will be used solely for the benefit of Company. Employee waives and
      releases any claim that he or she should be able to use client or customer
      goodwill, or Company's Proprietary Information, previously received or
      developed by Employee while working for the Company, for the benefit of
      any competing person or entity.

9. Protective Covenants. Employee agrees that the following covenants are
reasonable and necessary agreements for the protection of the business interests
of the Company.

      A. Definitions. "Competing Business" means any business involving service
      and/or refurbishment of semiconductor equipment or any related activities
      so similar in nature that it would displace business opportunities or
      customers of Company. "Covered Customer" means those customer entities
      and/or persons that the Company has an ongoing business relationship with
      (prior to any prohibited interference), or is negotiating with for such a
      relationship, and that Employee either (a) received Proprietary
      Information about in the course of his/her duties; or (b) had contact with
      within the last twenty-four (24) month period that Employee was employed
      with Company.

      B. Handling of Covered Items. All Proprietary Information, and/or Company
      materials containing Proprietary Information, shall remain the exclusive
      property of Company at all times. Such materials shall, together with all
      copies thereof, be returned and delivered to Company by Employee
      immediately (without demand) upon the termination of this Agreement, and
      shall be returned at a prior time if Company so demands.

      C. Restriction on Interfering with Employee Relationships. Employee agrees
      that during employment with Company, and for a period of twelve (12)
      complete calendar months following the termination of Employee's
      employment with Company, Employee will not, either directly or indirectly,
      hire, solicit or take away any of the employees or officers of Company, or
      encourage any employees or officers of Company to terminate their
      relationship with Company without prior written consent of the Chairman of
      the Company.

                                       6
<PAGE>

      D. Restriction on Interfering with Customer Relationships. Employee agrees
      that while performing services for Company, and for a period of twelve
      (12) complete calendar months following the termination of Employee's
      employment with Company, Employee will not, directly or indirectly, except
      in connection with Employee's employment with Company, service, solicit or
      take away any of the Covered Customers of Company for a Competing Company
      without the prior written consent of the Chairman of the Company. The
      parties stipulate that the foregoing restriction contains a reasonable
      geographic limitation because it is limited to the location, storefront,
      address or place of business where a Covered Customer is present and
      available for solicitation.

      E. Restriction on Unfair Competition. Employee agrees that during
      employment with Company, Employee will not participate in or assist a
      Competing Business. Employee agrees that for a period of twelve (12)
      complete calendar months following termination of services, Employee will
      not work for or assist a Competing Company in any capacity (as employee,
      consultant, contractor, officer, director, investor, agent or otherwise)
      that would involve (a) the same or substantially similar functions or
      responsibilities; or (b) supervision over the same or substantially
      similar functions or responsibilities; or (c) assisting a Competing
      Company in decisions within the "Restricted Area." "Restricted Area" means
      any state in which SemiQuip, Aspect SemiQuip International, Aspect
      Systems, Incorporated or DND Technologies is incorporated or authorized to
      do business, and that contains an office that Employee worked out of,
      provided services through or provided supervision over. Employee may not
      circumvent the purpose of any restriction by engaging in business in the
      Restricted Area through remote means like telephone, other oral or written
      correspondence or computerized communication. These restrictions do not
      prohibit ownership of less than 10% of the publicly traded capital stock
      of a corporation, or mutual fund investments. Employee will give Company
      thirty (30) days written notice prior to having any financial affiliations
      or going to work for a Competing Company.

      F. Reasonableness of Geographic Restriction. Employee agrees that
      provision contained herein are narrow and reasonable for the following
      reasons: (a) Employee is free to seek employment with other companies,
      providing services that do not directly or indirectly compete with any
      business of the Company; (b) Employee is free to seek employment with
      other companies in the semiconductor capital equipment industry that do
      not directly or indirectly compete with any business of the Company, such
      as any fabricator of some semiconductor components; and (c) there are many
      other companies in the semiconductor capital equipment industry that do
      not directly or indirectly compete with any business of the Company. Thus,
      this restriction on Employee's ability to compete does not prevent
      Employee from using and offering the skills that Employee possessed prior
      to receiving Confidential Information, specialized training and knowledge
      from the Company.

      G. Survival of Covenants. The restrictions, representations and warranties
      contained herein shall survive the termination of Employee's employment
      with Company to the extent necessary to carry out or to enforce the intent
      of the parties set forth herein. The existence of any claim or cause of
      action of Employee against Company whether

                                       7

      predicated on this Agreement or otherwise shall not constitute a defense
      to the enforcement by Company of said covenant. In the event an
      enforcement remedy is sought hereunder, the time periods of the
      restrictions, provided for herein shall be extended by one day for each
      day Employee failed to comply with the restriction at issue.

      H. Remedies. In the event of breach or threatened breach by Employee of
      any provision herein, Company shall be entitled to (i) injunctive relief
      by temporary restraining order, temporary injunction, and/or permanent
      injunction, (ii) recovery of all attorney's fees and costs incurred by
      Company in obtaining such relief, and (iii) any other legal and equitable
      relief to which it may be entitled, including any and all monetary damages
      which Company may incur as a result of said breach or threatened breach.
      An agreed amount for the bond to be posted is One Thousand Dollars
      ($1,000.00) if Company seeks an injunction.

10. Severability. In the event of any breach of this Agreement, the Company
shall have the right to exercise all of its legal rights and remedies including,
but not limited to the right to obtain injunctive relief, without the
requirement of posting a bond in support of such injunctive relief. If any
provision of this Agreement shall be held to be invalid or unenforceable for any
reason, the remaining provisions shall continue to be valid and enforceable. If
a court finds that any provision of this Agreement is invalid or unenforceable,
but that by limiting such provision it would become valid and enforceable, then
such provision shall be deemed to be written, constructed and enforceable as so
limited. It is the intention of the parties hereto that if any provision of this
Agreement is capable of two constructions, one of which would render the
provision void and the other of which would render it valid, then the provision
shall have the meaning which renders it valid.

11. Waiver, Modification and Integration. The waiver by any party hereto of a
breach of any provision of this Agreement shall not operate or be construed as a
waiver of any subsequent breach by any party. This instrument contains the
entire agreement of the parties concerning the matters covered in it. This
Agreement may not be modified, altered or amended except by written agreement of
all parties hereto, above or by order of the court.

12. Personal Services. This Agreement is for the personal services of the
Employee and may not be assigned by the Employee.

      B. Attorneys Fees to Prevailing Party. In the event that a dispute of any
      nature arises pertaining to this Agreement, including but not limited to
