          (f) Vacation. During the Term, Executive shall be entitled to four
              --------
     weeks of paid vacation per year so long as the absence of Executive does

     3.   Termination.
          -----------

              ----------------
     the mutual agreement of the Company and Executive, expressed in writing.

          (b) Voluntary. Executive may terminate this Agreement with or without
              ---------
     the consent of the Company by giving written notice of his intent to
     terminate with the effective date of termination at least one hundred (100)
     days after the effective date of the notice of termination. After such
     notice the Company may accelerate the date of termination without being in
     breach hereof.

     time without Cause upon twenty (20) days prior notice.

          (d) Disability or Death. The Company may terminate this Agreement upon
              -------------------
     the death or disability of Executive. For purposes of this Agreement,
     Executive shall be considered disabled if he is unable to perform his
     duties under this Agreement as a result of injury, illness or other
     disability for a period of one hundred eighty (180) consecutive days, or
     one hundred eighty (180) days in a three hundred sixty-five (365) day
     period, and the Board reasonably determines that Executive has been unable
     to perform his

<PAGE>

     duties for the one hundred eighty (180) day period as a result of injury,
     illness or other disability.

          (e)  For Cause by the Company. The Company may terminate this
               ------------------------
     Agreement for "Cause", as defined below, immediately upon written notice to
     Executive. "Cause" shall mean:

               (i)   If Executive materially violates any term of this Agreement
          and such action or failure is not substantially remedied or reasonable
          steps to effect such substantial remedy are not commenced within
          twenty (20) days of written notice from the Company to Executive.

               (ii)  Dishonesty which is not the result of an inadvertent or
          innocent mistake of Executive with respect to the Company or any of
          its subsidiaries;

               (iii) Willful misfeasance or nonfeasance of duty by Executive
          intended to injure or having the effect of injuring in some material
          fashion the reputation, business or business relationships of the
          Company or any of its subsidiaries or any of their respective
          officers, directors or employees;

               (iv)  Conviction of Executive upon a charge of any crime
          involving moral turpitude or a crime other than a vehicle offense
          which could reflect in some material fashion unfavorably upon the
          Company or any of its subsidiaries; or

               (v)   Willful or prolonged absence from work by the Executive
          (other than by reason of disability due to physical or mental illness)
          or failure, neglect or refusal by the Executive to perform his duties
          and responsibilities without the same being corrected upon twenty (20)
          days prior written notice.

          (f)  For Good Reason by the Executive. If (i) there is a material
               --------------------------------
     reduction or change of Executive's reporting relationship, job duties,
     responsibilities or requirements that is inconsistent with the position or
     positions listed in Section 1(a) and the Executive's prior reporting
     relationship, duties, responsibilities or requirements; (ii) there is a
     reduction in Executive's salary then in effect, other than a reduction
     comparable to reductions generally applicable to similarly situated
     employees of the Company; (iii) the Company requires Executive to relocate
     to a facility or location more than 50 miles from the Company's current
     location; or (iv) the Company materially breaches this Agreement, Executive
     may at his option terminate his employment and such termination shall be
     considered to be a termination of Executive's employment by the Company for
     reasons other than Cause. Such termination is a termination by Executive
     for Good Reason.

          (g)  Termination of Executive Upon Change of Control. In the event
               -----------------------------------------------
     Executive's employment is terminated prior to the Expiration Date by a
     Change of Control of the Company, as defined below, Company shall: (i) pay
     to Executive, in a lump sum within ten (10) days after the date Executive's
     employment is terminated, the amount of Executive's then current Base
     Salary pursuant to Section 2(a) above through

                                       4

     months, whichever is longer, beginning in the month next following such
     termination; (ii) pay to Executive the portion of the incentive
     compensation for the year of such termination which is (A) determined by
     objective measurement standards under Section 2(b), and (B) would have been
     paid to Executive had Executive been continuously employed under this
     Agreement through the Expiration Date. Payment of such portions of
     incentive compensation, if any, shall be made to Executive within 10
     business days after the date, if any, on which senior executives of Company
     receive payment of their incentive compensation under such incentive
     compensation program; and (iii) the Initial Stock Options shall irrevocably
     vest immediately prior to the consummation of a Change of Control (as
     defined below) and, if such event results in a successor firm, Executive
     shall receive, in lieu of the shares so vested, the cash, stock and other
     securities or property in the successor firm to which he would have been
     entitled if he had exercised the Initial Stock Options immediately prior to
     the Change of Control or, at the Company's election, the Initial Stock
     Options shall be converted into an equivalent number of like securities,
     fully vested as aforesaid, preserving the post-tax economics of the Initial
     Stock Options, including the substantive terms thereof. The term of the
     Initial Stock Options shall be ten years from the date of grant. The
     Initial Stock Options shall not be transferable except by will or by reason
     of the laws of descent and distribution. Thereafter Executive shall not be
     entitled to receive, and the Company shall not be obligated to provide
     Executive with any additional salary, payments or benefits of any kind
     other than those specifically set forth in this Section 3(g).

          As used herein, "Change of Control" shall mean the occurrence of one

          than a liquidation or dissolution occurring after any of the following
          transactions: the merger or consolidation of the Company with an
          Affiliate, the transfer of fifty percent (50%) or more of the Voting
          Stock of the Company to an Affiliate or Affiliates or the sale or
          other transfer of all or substantially all of the assets of the
          Company to an Affiliate or Affiliates;

               (iii) the sale of all or substantially all of the Company's
          assets to a single purchaser or group of affiliate purchasers, other
          than any Affiliate or Affiliates; or

               (iv)  the Company engages in a merger or consolidation with
          another entity other than an Affiliate and immediately after that
          merger or consolidation, the persons or entities which were
          shareholders of the Company immediately prior to that merger or
          consolidation hold, directly or indirectly, less than fifty person
          (50%) of the Voting Stock of the surviving entity.

                                       5
<PAGE>

          "Affiliate" shall mean any corporation, partnership, trust or other
     entity of which the Company and/or any of its Affiliates directly or
     indirectly owns a majority of the outstanding shares of any class of equity

          "Voting Stock" shall mean, with respect to a corporation, the capital
     stock of any class or classes of that corporation having general voting
     power under ordinary circumstances, in the absence of contingencies, to
     elect directors of such corporation and, with respect to any other entity,
     the securities of that entity having such general voting power to elect the
     members of the managing body of that entity.

     4.   Payments at Termination.
          -----------------------

          (a) Upon (i) termination of this Agreement by the Company under
     Section 3(c) titled "Without Cause" or (ii) termination of this Agreement
     by Executive under Section 3(f) titled "For Good Reason by the Executive,"
     Executive shall receive monthly payments equal to his Base Salary prior to
     termination ("Applicable Base Salary") through the termination date of this
     Agreement or for a period of eighteen (18) months, whichever is longer,
     beginning in the month next following such termination. In either case
     Executive shall receive all accrued compensation and unreimbursed expenses
     to the date of termination as provided herein. The monthly payments
     provided for in this Section 4(a) shall be paid in accordance with the
     Company's normal payroll schedule, less applicable tax withholdings for
     state and federal taxes and other deductions required by law and shall not
     be reduced by compensation the Executive may receive from other sources. In
     either such case of termination, all unexercised options granted pursuant
     to the Company's stock option plan (the "Plan") shall vest and become
     exercisable on the day of termination. For any such non-statutory stock
     option or incentive stock option, the period for exercise of the option
     shall continue for the shorter of the maximum length of time the option is
     exercisable under the Plan as though the service of Executive had not
     terminated, and three (3) years after the date of termination of service,
     provided, however, that if the existence of this sentence would cause any
     incentive stock option not to qualify as an incentive stock option pursuant
     to Section 422 of the Internal Revenue Code of 1986, as amended, ("Section
     422") at any time prior to ninety (90) days after termination of employment
     as provided in Section 422, this sentence shall be null and void as to such
     incentive stock option.

          (b) If the Company terminates this Agreement due to disability, under
     Section 3(d) titled "Disability or Death," Executive or his estate shall
     receive the disability payments provided for by the Company's disability
     insurance policy.

          (c) If Executive terminates this Agreement without cause under Section
     3(b), titled "Voluntary", or if this Agreement is terminated under Section
     3(a), titled "Mutual Agreement," or if this Agreement is terminated by the
     Company under Section 3(e) titled "For Cause by the Company," Executive
     shall not be entitled to any further payments

                                       6
<PAGE>

     except unreimbursed expenses to the date of termination as provided herein
     and any accrued compensation and as provided in Section 4(d).

          (d) In each of the foregoing cases, termination is the date of actual
     termination, not the date notice of termination is given. Other than
     payments owing under a provision providing for payments at a different
     time, all payments for accrued unpaid monthly compensation shall be made
     within ten (10) days after the end of the month following the month in
     which termination occurred and all payments for reimbursement shall be made
     within forty-five (45) days after the end of the month following the month
     in which termination occurred.

          (e) Unless specified otherwise in any bonus plan or bonus agreement,
     if termination occurs during a bonus period pursuant to Section 3(c).
     titled "Without Cause" or Section 3(f) titled "For Good Reason by the
     Executive," or Section 3(d) titled "Disability or Death," and based upon
     the results of the full bonus period the bonus would have been earned, any
     bonus which would have been earned shall be based upon the number of
     calendar days in such bonus period which have elapsed at the date of
     termination. Unless specified otherwise in any such bonus plan or bonus
     agreement, if Executive is terminated "For Cause by the Company" (Section
     4(e)), or Executive terminates without Cause (Section 4(c).) or Executive
     after termination violates a confidentiality, covenant not to compete, or
     "no hire" or "no raid" agreement with the Company, its parent (if any) or a
     direct or indirect Company subsidiary or affiliate, then the Company shall
     have no obligation to pay any earned or unearned bonus or the payments
     provided for in the first sentence of Section 4(a) hereof.

          (f) The foregoing rights in this Section 4 are Executive's exclusive
     rights to payment from the Company in the event of termination of this
     Agreement except for amounts which the Company is required to pay under
     applicable statute or regulation, payments under insurance policies, and
     payments owing under other written agreement(s) (if any) between the
     Company and Executive.

          (g) Employment at Will After Termination of Agreement. If, upon the
              -------------------------------------------------
     termination of this Agreement pursuant to Section 3, the parties to this
     Agreement agree that Executive shall remain employed by the Company, then
     Executive's employment with the Company will continue in accordance with,
     and subject to, the terms and conditions of this Agreement, except that
     Executive's continued employment will not be for any specific term but will
     be at-will and either the Company or Executive may terminate the employment
     relationship at any time for any reason whatsoever. If the Company then
     terminates the employment of Executive pursuant to Section 3(c) or
     Executive terminates the relationship for Good Reason pursuant to Section
     3(f), Executive shall be entitled to his salary and bonus through the date
     of termination. If the Company terminates the employment of Executive for
     Cause pursuant to Section 3(e) or Executive voluntarily terminates his
     employment pursuant to Section 3(b), Executive shall be entitled to his
     salary through the date of termination and no bonus payments.

     5.   Non-Competition.
          ---------------

          (a) Executive covenants and agrees with the Company that so long as he
     is employed by the Company and for a period of the longer of (i) twelve
     (12) months after termination of Executive's employment for any reason or
     (ii) during which any payments are made to Executive or for his benefit
     following termination of his employment pursuant to Section 4 of this
     Agreement, Executive will not engage or participate, directly or
     indirectly, as principal, agent, employee, employer, consultant, advisor,
     sole proprietor, stockholder, partner, independent contractor, trustee,
     joint venturer or in any other individual or representative capacity
     whatever, in the conduct or management of, or own any stock or other
     proprietary interest in, or debt of, any business organization, person,
     firm, partnership, association, corporation, enterprise or other entity
     that shall be engaged in any business (whether in operation or in the
     planning, research or development stage) that is a Competitive Business
     anywhere in the Restricted Territory, unless Executive shall obtain the
     prior written consent of the Board, given in its sole discretion, which
     consent shall make express reference to this Agreement. Notwithstanding the
     foregoing, Executive may make passive investments in any company whose
     stock is listed on a national securities exchange or traded in the
     over-the-counter market so long as he does not come to own, directly or
     indirectly, more than five percent (5%) of the equity securities of such
     company. For purposes of this Agreement, a business shall be considered a
     "Competitive Business" if it involves or relates to (i) any business in
     which the Company is actively engaged on the date of termination or any
     business in which during the twelve (12) months immediately preceding the
     date of termination the Company actively contemplated engaging (as
     evidenced by inclusion in a written business plan or proposal) or (ii) any
     business in which an Affiliate is actively engaged on the date of
     termination or any business in which during the twelve (12) months
     immediately preceding the date of termination an Affiliate actively
     contemplated engaging (as evidenced by inclusion in a written business plan
     or proposal). The term "Restricted Territory" shall mean each and every
     county, province, state, city or other political subdivision of the United
     States.

          (b) During the time of Executive's employment and for the longer of
     (i) twelve (12) months after termination of Executive's employment for any
     reason or (ii) during which any payments are made to Executive or for his
     benefit following termination of his employment pursuant to Section 4 of
     this Agreement, without the express, prior written consent of an executive
     officer of the Company, Executive shall not engage in any of the following
     conduct:

              (i) Hire, attempt to hire or assist any other person or entity in
          hiring or attempting to hire any current employee of the Company or
          any person who was a Company employee within the three (3) month
          period prior to the termination of Executive's employment; provided,
          however that this prohibition on solicitation of the Company's
          employees shall not apply to the person acting as the Executive's
          current executive assistant as of the date of termination of
          Executive's employment; and provided further that Executive agrees
          that Executive will provide the Company with thirty (30) days prior
          written notice of Executive's

                                       8
<PAGE>

          intent to solicit and/or hire such executive assistant upon
          Executive's termination of employment.

              (ii) Solicit, divert, or take away, in competition with the
          Company, the business or patronage of any current Company customer.
          Notwithstanding the foregoing, this restriction shall not apply to any
          person or entity who is no longer a customer at the time of any such
          solicitation by Executive.

          (c) Executive agrees that if he acts in violation of Sections 5 or 7
     of this Agreement, the number of days that such violation exists will be
     added to any period of limitations on the specific activities.

          (d) The covenants contained in paragraph (a) shall be construed as a
     series of separate covenants, one for each county, province, state, city or
     other political subdivision of the Restricted Territory. Except for
     geographic coverage, each such separate covenant shall be deemed identical
     in terms to the covenant contained in paragraph (a). If, in any judicial
     proceeding, a court refuses to enforce any of such separate covenants (or
     any part thereof), then such unenforceable covenant (or such part) shall be
     eliminated from this Agreement to the extent necessary to permit the
     remaining separate covenants (or portions thereof) to be enforced. In the
     event that the provisions of this Section 5 are deemed to exceed the time,
     geographic or scope limitations permitted by applicable law, then such
     provisions shall be reformed to the maximum time, geographic or scope
     limitations, as the case may be, permitted by applicable laws.

          (e) Without limitation of any of the provisions of this Section 5, any
     payments to be made to Executive or for his benefit following termination
     of his employment with the Company pursuant to Section 4 of this Agreement
     shall be deemed to secure his agreements set forth in this Section 5 and
     such payments may be terminated by the Company if Executive fails to
     observe the agreements set forth in this Section 5 and fails to cure such
     failure within ten (10) days of receipt of written notice of such failure.

          (f) Executive (i) acknowledges that his skills and experience are such
     that he can anticipate finding employment at a senior level in his
     profession, and (ii) represents and agrees that the restrictions imposed by
     this Section 5 on engaging in competitive business activities are necessary
     for the protection of the legitimate interests and competitive position of
     the Company and do not impose undue hardships on him.

     6.   Termination Obligations of Executive
          ------------------------------------

          (a) Return of the Company's Property. Executive hereby acknowledges
              --------------------------------
     and agrees that all personal property, including, without limitation, all
     books, manuals, records, reports, notes, contracts, lists, files, disks and
     other media with Company information, blueprints, and other documents, or
     materials, or copies thereof, and equipment furnished to or prepared by
     Executive in the course of or incident to Executive's employment, belong to
     the Company and shall be promptly returned to the Company upon termination
     of Executive's employment.

          (b) Cooperation in Pending Work. For two (2) months after termination
              ---------------------------
     of Executive's employment, Executive agrees to fully cooperate with the
     Company in all matters relating to the winding up of pending work on behalf
     of the Company and the orderly transfer of work to other employees of the
     Company following any termination of Executive's employment. For two (2)
     years after termination of Executive's employment, Executive shall also
     cooperate in the resolution of any dispute, including litigation of any
     action, involving the Company that relates in any way to Executive's
     activities while employed by the Company. In the event, however,
     Executive's services to the Company under this Section 6(b) exceed forty
     (40) hours, the Company shall pay Executive for his services at a rate
     equivalent to his Base Salary at the time of termination of employment and
     shall pay Executive's out-of-pocket expenses incurred in connection with
     his services. Executive shall not be entitled to compensation under this
     Section 6(b) if Executive is terminated for "Cause" as defined in Section
     3(e) of this Agreement. Such activities and all such activities shall be
     scheduled for mutually convenient times.

     7.   Confidentiality.
          ---------------

          (a) Confidential Information. Executive acknowledges that he has had
              ------------------------
     and will have access to certain information related to the business,
     operations, future plans and customers of the Company, the disclosure or
     use of which could cause the Company substantial losses and damages.
     Accordingly, Executive covenants that during the term of his employment
     with the Company and thereafter he will keep confidential all information
     and documents furnished to him by or on behalf of the Company and not use
     the same to his advantage, except to the extent such information or
     documents are lawfully obtained from other sources on a non-confidential
     (as to the Company) basis or are in public domain through no fault on his
     part or is consented to in writing by the Company.

          (b) Innovations, Patents, and Copyrights. Executive agrees to promptly
              ------------------------------------
     disclose, in writing, all Innovations to the Company. Executive further
     agrees to provide all assistance requested by the Company, at its expense,
     in the preservation of its interests in any Innovations, and hereby assigns
     and agrees to assign to the Company all rights, title and interest in and
     to all worldwide patents, patent applications, copyrights, trade secrets
     and other intellectual property rights or "Moral Rights" in any Innovation.
     Furthermore, during the term of this Agreement, the Company may, with
     Executive's written permission (such permission not to be unreasonably
     withheld), use Executive's name and image as appropriate in the conduct of
     its business.

          "Innovations" shall mean all developments, improvements, designs,
     original works of authorship, formulas, processes, software programs,
     databases, and trade secrets, whether or not patentable, copyrightable or
     protectable as trade secrets, that Executive by himself or jointly with
     others, creates, modifies, develops, or implements during the period of
     Executive's employment which relate in any way to the Company's business.
     The term Innovations shall not include Innovations developed entirely on
     Executive's own time without using the Company's equipment, supplies,
     facilities or Confidential Information, and which neither relate to the
     Company's business, nor result from any work performed by or for the
     Company.

     8. Right to Injunctive Relief. Executive agrees and acknowledges that a
        --------------------------
violation of the covenants contained in Sections 5, 6 and 7 of this Agreement
will cause irreparable damage to the Company, and that it is and may be
impossible to estimate or determine the damage that will be suffered by the
Company in the event of a breach by Executive of any such covenant. Therefore,
Executive further agrees that in the event of any violation or threatened
violation of such covenants, the Company shall be entitled as a matter of course
to an injunction out of any court of competent jurisdiction restraining such
violation or threatened violation by Executive, such right to an injunction to
be cumulative and in addition to whatever other remedies the Company may have.

     9. Alternative Dispute Resolution. The Company and Executive mutually agree
        ------------------------------
that any controversy or claim arising out of or relating to this Agreement or
the breach thereof, or any other dispute between the parties relating in any way
to Executive's employment with the Company or the termination of that
relationship, including disputes arising under the common law and/or any federal
or state statutes, laws or regulations, shall be submitted to mediation before a
mutually agreeable mediator, which cost is to be borne equally by the parties.
In the event mediation is unsuccessful in resolving the claim or controversy,
such claim or controversy shall be resolved exclusively by binding arbitration.
The claims covered by this Agreement ("Arbitrable Claims") include, but are not
limited to, claims for wages or other compensation due; claims for breach of any
contract (including this Agreement) or covenant (express or implied); tort
claims; claims for discrimination (including, but not limited to, race, sex,
religion, national origin, age, marital status, medical condition, or
disability); claims for benefits (except where an employee benefit or pension
plan specifies that its claims procedure shall culminate in an arbitration
procedure different from this one), and claims for violation of any federal,
state, or other law, statute, regulation, or ordinance, except claims excluded
in the following paragraph. The parties hereby waive any rights they may have to
trial by jury in regard to Arbitrable Claims.

     Claims Executive or the Company may have regarding Workers' Compensation or
unemployment compensation benefits and the noncompetition provisions of this
Agreement are not covered by the arbitration and mediation provisions of this
Agreement. Claims Executive or the Company may have for violation of the
proprietary information provisions of this Agreement as well as the terms and
provisions of Exhibit A of this Agreement are not covered by the arbitration and
mediation provisions of this Section 9 of this Agreement.

     Arbitration under this Agreement shall be the exclusive remedy for all
Arbitrable Claims. The Company and Executive agree that arbitration shall be
held in or near either Boulder or Denver, Colorado and shall be in accordance
with the then-current Employment Dispute Resolution Rules of the American
Arbitration Association, before an arbitrator licensed to practice law in
Colorado. The arbitrator shall have authority to award or grant both legal,
equitable, and declaratory relief. Such arbitration shall be final and binding
on the parties. The Federal Arbitration Act shall govern the interpretation and
enforcement of this Section 9 pertaining to Alternative Dispute Resolution.

     This Agreement to mediate and arbitrate survives termination of Executive's
employment.
