Employer's then outstanding securities, or (B) if, during any period of two
consecutive years during the term of this Agreement, individuals who at the
beginning of such period constitute the Board cease for any reason to constitute
at least a majority thereof, unless the election of each director who was not a
director at the beginning of such period has been approved in advance by
directors representing at least two-thirds of the directors then in office who
were directors at the beginning of the period; or

               (iv)  within 90 days following a change in control of Employer.

the Company advising Executive of the specific acts or omissions alleged to
constitute such negligent or willful misconduct, and such misconduct continues
uncured by Executive for a period of twenty (20) days; or

               (iv)  a material breach by Executive of the terms of this
Agreement and a failure by Executive to cure such breach within twenty (20) days

Executive's employment hereunder other than for Cause upon written notification
to Executive given at any time.

          -------------
accordance with the laws of the State of Colorado.

     6.2  Arbitration.  Any and all disputes arising under or related to this

Agreement which cannot be resolved through negotiations between the parties
shall be submitted to binding arbitration.  If the parties fail to reach a
settlement of their dispute within fifteen (15) days after the earliest date
upon which one of the parties notified the other(s) of its desire to attempt to
resolve the dispute, then the dispute shall be promptly submitted to arbitration
by a single arbiter through the Judicial Arbiter Group ("JAG"), any successor of
the Judicial Arbiter Group, or any similar arbitration provider who can provide
a former judge to conduct such arbitration if JAG is no longer in existence, or
an arbiter appointed by the court.  The arbiter shall be selected by JAG or the
court on the basis, if possible, of his or her expertise in the subject
matter(s) of the dispute.  The decision of the arbiter shall be final, non-
appealable and binding upon the parties, and it may be entered in any court of
competent jurisdiction.  The arbitration shall take place in Boulder, Colorado.
The arbitrator shall be bound by the laws of the State of Colorado applicable to
the issues involved in the arbitration and all Colorado rules relating to the
admissibility of evidence, including, without limitation, all relevant
privileges and the attorney work product doctrine.  All such discovery shall be
completed in accordance with the time limitations prescribed in the Colorado
Rules of Civil Procedure, unless otherwise agreed by the parties or ordered by
the arbitrator on the basis of strict necessity adequately demonstrated by the
party requesting an extension or reduction of time.  The arbitrator shall have
the power to grant equitable relief where applicable under Colorado law.  The
arbitrator shall issue a written opinion setting forth her or his decision and
the reasons therefor within thirty (30) days after the arbitration proceeding is
concluded.  The obligation of the parties to submit any dispute arising under or
related to this Agreement to arbitration as provided in this Section shall
survive the expiration or earlier termination of this Agreement.
Notwithstanding the foregoing, either party may seek and obtain an injunction or
other appropriate relief from a court to preserve or protect the status quo with
respect to any matter pending conclusion of the arbitration proceeding, but no
such application to a court shall in any way be permitted to stay or otherwise
impede the progress of the arbitration proceeding.

          ----------------
convenience only and shall not affect the construction of any terms of this

prior to such termination.

     6.9  Amendments.  No waiver or modification of this Agreement or any

nor herein makes, any representation about the tax consequences of any
consideration provided by Employer to Executive pursuant to this Agreement or
any Stock Option Agreement. Executive further acknowledges that all such
consideration shall be subject to various taxes and withholding which shall be
made by Employer.  It is also possible that amounts or benefits paid or
distributed to the Executive pursuant to this Agreement, taken together with any

tax is triggered, Employer may limit its payments as follows: If (x) the
aggregate value of all compensation payments or benefits to be paid or provided
to the Executive under this Agreement and any other plan, agreement, or
arrangement with Employer exceeds the amount which can be paid to the Executive
without the Executive incurring an Excise Tax and (y) the Executive would
receive a greater net after-tax amount (taking into account all applicable taxes
payable by the Executive, including any Excise Tax) by applying the limitation
contained in this Paragraph, then the amounts payable to the Executive under
this Agreement shall be reduced (but not below zero) to the maximum amount which
may be paid hereunder without the Executive becoming subject to such an

                                       9
<PAGE>

Excise Tax (such reduced payments to be referred to as the "Payment Cap").
In the event that Executive receives reduced payments and benefits hereunder,
Executive shall have the right to designate which of the payments and benefits
otherwise provided for in this Agreement that Executive will receive in
connection with the application of the Payment Cap. If the Executive receives
reduced payments and benefits under this Paragraph (or the Payment Cap is
determined not to be applicable to the Executive because the parties conclude
that Executive is not subject to any Excise Tax) and it is established pursuant
to a final determination of a court or an Internal Revenue Service proceeding (a
"Final Determination") that, notwithstanding the good faith of the Executive and
Employer in applying the terms of this Agreement, the aggregate "parachute
payments" within the meaning of Section 280G of the Code paid to the Executive
or for his  benefit are in an amount that would result in the Executive being
subject an Excise Tax, then the amount equal to such excess parachute payments
shall be deemed for all purposes to be a loan to the Executive made on the date
of receipt of such excess payments, which the Executive shall have an obligation
to repay to Employer on demand, together with interest on such amount at the
applicable federal rate (as defined in Section 1274(d) of the Code) from the
date of the payment hereunder to the date of repayment by the Executive.  If
this Paragraph is not applied to reduce the Executive's entitlements under this
Paragraph because the parties determine that the Executive would not receive a
greater net after-tax benefit by applying this Paragraph and it is established
pursuant to a Final Determination that, notwithstanding the good faith of the
Executive and Employer in applying the terms of this Agreement, the Executive
would have received a greater net after-tax benefit by subjecting his payments
and benefits hereunder to the Payment Cap, then the aggregate "parachute
payments" paid to the Executive or for his benefit in excess of the Payment Cap
shall be deemed for all purposes a loan to the Executive made on the date of
receipt of such excess payments, which the Executive shall have an obligation to
repay to Employer on demand, together with interest on such amount at the
applicable federal rate (as defined in Section 1274(d) of the Code) from the
date of the payment hereunder to the date of repayment by the Executive.  If the
Executive receives reduced payments and benefits by reason of this Paragraph and
it is established pursuant to a Final Determination that the Executive could
have received a greater amount without exceeding the Payment Cap, then Employer
shall promptly thereafter pay the Executive the aggregate additional amount
which could have been paid without exceeding the Payment Cap.

     WHEREAS, Executive is being promoted as of the date hereof to the offices
of President and Chief Executive Officer of the Company, and in such positions
is a key, valued executive employee of the Company, and, as such, is in a
position to damage the business of the Company by engaging in competing
activities; and

     WHEREAS, the Company wishes to protect itself from competitive activities

inevitable disclosure of trade secret information; and

     WHEREAS, it is a condition of the promotion of Executive, as described
above Executive has agreed not to compete with the Company during, or for a
period of two years after, his employment with the Company;

     NOW, THEREFORE, in consideration of the promotion of Executive, for the

     1.   Executive agrees that he possesses or will possess the knowledge,
skills and reputation in the outsourcing industry in which the Company operates
which are of material importance to the Company, and which are special, unique
and extraordinary.  Executive acknowledges that his services cannot be replaced
and that the loss of his services, or the use of his services by a competitor,
may cause the inevitable disclosure of trade secret information and other
irreparable harm to the Company.  Therefore, Executive agrees that during the
period commencing with the date hereof and ending two  (2) years after his
employment with the Company is terminated (voluntarily or involuntarily) he will
not, knowingly, directly or indirectly, as a principal, officer, director,
shareholder (other than as a holder of 5% or less of a publicly traded
corporation's capital stock), partner, become employed by, consult for or with,
or in any other capacity whatsoever, engage in, be or become associated with, or
advise or assist any business, firm, partnership, individual, corporation, or
any other entity which is engaged in any outsourcing business engaged in, or
anticipated to be engaged in, by the Company as of his Date of Termination, as
defined in Executive's Executive Employment Agreement, anywhere in the United
States of America.

     2.   Executive acknowledges that Company has invested substantial time and
effort in assembling its present staff of personnel.  Executive agrees that so
long as he is employed by the Company and during two (2) years immediately
thereafter, Executive shall not either directly or indirectly employ, solicit
for employment or advise or recommend to any other person that a third party
employ or solicit for employment, any of the Company's employees.

     3.   Executive agrees that so long as he is employed by the Company and
during two (2) years immediately thereafter, Executive shall not either directly
or indirectly solicit business, as to products or services competitive with the
business of the Company from any of Company's customers with whom Executive had
contact during his employment. Executive agrees that during such post-employment
period he will not influence or attempt to interfere with any of Company's
relationships with its investors, customers or clients.

two (2) years immediately thereafter, Executive shall not either directly or
indirectly interfere with any relationship between the Company and any of its
suppliers, clients or their employees.

     5.   Any waiver of any of the terms and conditions of this Agreement shall
not operate as a waiver of any other breach of such terms or conditions, or any
other term or condition, nor shall any failure to enforce any provision hereof
operate as a waiver of such provision or any other provision hereof.

     6.   It is agreed that Executive's services are unique, and that any breach
or threatened breach by Executive of any provisions of this Agreement may not be
remedied solely by damages.  Accordingly, in the event of a breach or threatened
breach by Executive of any of the provisions of this Agreement, the Company
shall be entitled to injunctive relief, restraining Executive and any business,
firm, partnership, individual, corporation, or entity participating in such
breach or attempted breach, from engaging in any activity which would constitute
a breach of this Agreement.  Nothing herein, however, shall be construed as
prohibiting the Company from pursuing any other remedies available at law or in
equity for such breach or threatened breach, including the recovery of damages.

     7.   The restrictive period for all of the aforementioned covenants shall
be extended for every day that Executive is in violation of any one of the
covenants.

     8.   Any and all notices referred to herein shall be sufficient if

the laws of the State of Colorado.

     10.  No modification or changes in this Agreement shall be valid unless
such modification or changes are in writing and signed by all parties hereto.

     11.  The invalidity or unenforceability of any provision in this Agreement
shall not affect the other provisions hereof.  This Agreement shall be construed

extent necessary to make this Agreement valid and enforceable.

     12.  Company may assign this Agreement to its successors. Executive may not
assign this Agreement without the prior written approval of the Company.

     13.  Any controversy or claim arising out of or relating to this Agreement
or the breach thereof shall be settled by arbitration in Boulder, Colorado in
accordance with the rules then existing of the American Arbitration Association
and judgment upon the award may be entered in any court having jurisdiction

                     Request for Post-Employment Allowance

     This request for severance allowance is made by ___________(hereinafter

     1.   In consideration of the execution of this request for post-employment

     2.   In return for these payments, I fully and finally release, waive and
          discharge Company, including any of its parents, subsidiaries, or
          otherwise affiliated corporations, partnerships or business
          enterprises, and their respective present and former directors,
          shareholders, employees, assigns, insurers and employee benefit
          administrators (hereinafter "Released Parties") from all charges,
          claims and causes of action of any sort which I may have, including
          but not limited to, claims arising from or related to my employment or
          termination of my employment, any age, race, any unlawful employment
          practices of any kind, whether such claims arise under federal, state,
          local, common, contract, tort or other laws or regulations,
          specifically including Title VII of the Civil Rights Act of 1964 as
          amended by the Equal Employment Opportunity Act of 1972 and the Age
          Discrimination in Employment Act, 42 U.S.C. Section 1981. BY SIGNING
          THIS AGREEMENT, I ACKNOWLEDGE THAT COMPANY HAS ADVISED ME TO DISCUSS
          THIS AGREEMENT WITH AN ATTORNEY BEFORE SIGNING IT. I further
          acknowledge and agree that the Company is not responsible for any of
          my costs, expenses, and attorneys' fees, if any, incurred in
          connection with the review and signing of this Agreement. I
          acknowledge that I have been given a period of at least twenty-one
          (21) days in which to consider the terms of this Agreement.  If I have
          chosen to waive the twenty-one day period, I represent that I did so
          voluntarily without any pressure by Company. I also understands that I
          have the right to revoke this Agreement at any time within seven (7)
          days after signing it, by providing written notice to Company, and
          that upon such revocation, this Agreement will not have any further
          legal effect.

     3.   I represent and warrant that I have returned all property of the
          Company in my possession, including but not limited to, documents,
          manuals, pertinent business contacts (names and addresses),
          shareholder lists, software, computers and computer disks, notes,
          keys, cellular phone, and other articles or equipment I used in the
          course of my employment.

     4.   It is understood that the Company does not admit the existence or
          validity of any such claims or any liability of any sort nor has the
          Company made any agreement or promise to do or omit to do any act or
          thing not herein set forth.

     5.   I agree that I will not disclose this document or its terms or
          provisions without first obtaining the written consent of the Company.

     6.   I understand that this Request shall be governed by Colorado law.

     7.   I have read and completely understand this request and recognize that
          it constitutes a general release and waiver of all claims, and I agree
          that this is an acceptable compromise of any such claims and knowingly
          and voluntarily intend to be bound by these provisions without any
          further promises or consideration by the Company. I further agree that
          this agreement terminates all other agreements between myself and the
          Company, excluding any non-disclosure or non-compete obligations which
          may survive my employment. As such, except as provided in this
          Agreement, I am not entitled to any other benefits as a result of my
