         ------

     (a) Pursuant to the request of Borrower and in accordance with Section 16.6

          (i) any  noncompliance  with (A) Section 7.3 of the Loan and  Security

     the  Merger  Documents  and  the  consummation  of the  DynCorp  Management
     Merger),  (B) Section  7.9 of the Loan and  Security  Agreement  (solely by
     reason of the indirect  Change of Control caused by the issuance of Class B
     Common  Stock  of  Parent  to  DynCorp  as  consideration  for the  DynCorp
     Management Merger) or (C) Sections 7.13(a) and (c) of the Loan and Security

     Merger); and

          (ii) any  noncompliance  with  Section  7.5 of the  Loan and  Security
     Agreement  solely  by  reason  of  Borrower  changing  its name to  "DynTek
     Services, Inc."

     (b)  Notwithstanding  the foregoing,  the waivers and consents set forth in
paragraph  (a)(i)  above shall be  automatically  rescinded  without any further

                                       3

     (c) This  waiver  and  consent  shall  be  effective  only in the  specific
instances and for the specific  purposes set forth herein and does not allow any

Security Agreement and other Loan Documents,  which terms shall continue in full
force and effect.  Without  limiting  the  generality  of the  foregoing,  it is
understood  and agreed that nothing in this Amendment No. 11 and Waiver shall be
deemed a waiver of any other  Event of  Default  or  Default,  whether  known or
unknown by Foothill and whether now existing or hereafter arising.
