     Class A Common Stock hereunder (collectively, the "Securities") for its own
                                                        ----------
     account, not as a nominee or agent, for investment only and not with a view
     towards, or for resale in connection with, the public sale or distribution
     thereof.

               (ii)   Accredited Investor Status.  Purchaser is an "accredited
                      --------------------------
     investor" as that term is defined in Rule 501(a)(3) of Regulation D.

               (iii)  Qualified Institutional Buyer.  Purchaser is a "qualified
                      -----------------------------
     institutional buyer", as such term is defined in Rule 144A promulgated
     under the Securities Act.

               (iv)   Reliance on Exemptions. Purchaser understands that the
                      ----------------------
     Securities are being offered and sold to it in reliance on specific
     exemptions from the registration requirements of United States federal and
     state securities laws and that the Company is relying in part upon the
     truth and accuracy of, and Purchaser's compliance with, the
     representations, warranties and agreements of Purchaser set forth herein in
     order to determine the availability of such exemptions and the eligibility
     of Purchaser to acquire such securities.

               (v)    No General Solicitation. The Purchaser initiated
                      -----------------------
     discussions with the Company relating to the purchase and sale of the
     Securities contemplated by this Agreement on an unsolicited basis prior to
     the date of this Agreement. The Purchaser did not initiate such
     discussions, nor did Purchaser decide to enter into this Agreement, as a
     result of any general solicitation or general advertising within the
     meaning of Rule 502(c) under the Securities Act, including the filing of
     the Registration Statement.

               (vi)   Information.  Purchaser has been furnished with all
                      -----------
     materials relating to the business, finances and operations of the Company
     and materials relating to the offer and sale of the Securities which have
     been requested by Purchaser. Purchaser

                                       4
<PAGE>

     has been afforded the opportunity to ask questions of the Company.
     Purchaser understands that its investment in the Securities involves a high
     degree of risk. Purchaser has sought such accounting, legal and tax advice
     as it has considered necessary to make an informed investment decision with
     respect to its acquisition of the Securities. The Purchaser has received
     and reviewed a copy of Amendment No. 2 to the Company's Registration
     Statement on Form S-1 as filed with the Securities and Exchange Commission
     on February 14, 2000, including without limitation, the language therein
     under the caption "Risk Factors" (the "Registration Statement").

               (vii)   No Governmental Review.  Purchaser understands that no
                       ----------------------
     United States federal or state agency or any other government or
     governmental agency has passed on or made any recommendation or endorsement
     of the Securities or the fairness or suitability of the investment in the
     Securities nor have such authorities passed upon or endorsed the merits of
     the offering of the Securities.

               (viii)  Transfer or Resale.  Purchaser understands that: (a) the
                       ------------------
     Securities have not been and are not being registered under the Securities
     Act or any state securities laws, and may not be offered for sale, sold,
     assigned or transferred unless (A) subsequently registered thereunder or
     (B) sold in reliance on an exemption therefrom; and (b) neither the Company
     nor any other person is under any obligation to register such securities
     under the Securities Act or any state securities laws or to comply with the
     terms and conditions of any exemption thereunder.  In this regard,
     Purchaser represents that it is familiar with SEC Rule 144, and understands
     the resale limitations imposed thereby and by the Securities Act.
     Purchaser is able to bear the economic risk of its investment in the
     Securities for an indefinite period of time.

               (ix)    Sophistication. Purchaser is an investor in securities of
                       --------------
     companies in the development stage and acknowledges that it is able to fend
     for itself, has knowledge and experience in financial and business matters,
     knows of the high degree of risk associated with investments generally and
     particularly investments in the securities of companies in the development
     stage, is capable of evaluating the merits and risks of an investment in
     the Securities and is able to bear the economic risk of an investment in
     the Securities in the amount contemplated.  Purchaser has adequate means of
     providing for its current financial needs and contingencies and will have
     no current or anticipated future needs for liquidity which would be
     jeopardized by the investment in the Securities.  Purchaser can afford a
     complete loss of its investment in the Securities.

               (x)     Further Limitations of Disposition.  Without in any way
                       ----------------------------------
     limiting the representations set forth above, the Purchaser agrees not to
     make any disposition of all or any portion of the Securities unless and
     until:

                       (1) There is then in effect a registration statement
          under the Securities Act covering such proposed disposition and such
          disposition is made in accordance with such registration statement; or

                                       5
<PAGE>

          the proposed disposition and shall have furnished the Company with a
          detailed statement of the circumstances surrounding the proposed
          disposition, and (ii) if reasonably requested by the Company, the
          Purchaser shall have furnished the Company with an opinion of counsel,
          reasonably satisfactory to the Company, that such disposition will not
          require registration of such shares under the Securities Act.

          4E.  Purchaser's Principal Place of Business.  The Purchaser
               ---------------------------------------
represents that its principal place of business is One Microsoft Way, Redmond,
Washington.

          4F.  Solicitation of Proxies.  Purchaser will not participate in any
               -----------------------
solicitation of proxies by anyone other than the Company with respect to the
voting of the Securities.

          4G.  Notice.  Purchaser shall notify the Company no later than 15 days
               ------
prior to Purchaser's acquisition of an additional number of securities of the
Company in an amount equal to greater than 1% of the Company's then outstanding
capital stock, and all such acquisitions shall comply with federal and state
securities laws.

          4H.  No Group.  Purchaser shall not form or participate in a "group"
               --------
(as defined in Rule 13d-5 of the Exchange Act) with respect to any securities of
the Company.

          Section 5.  Intentionally Omitted.

          Section 6.  Conditions of the Purchaser's Obligations at the Closing.
                      --------------------------------------------------------

is subject to the fulfillment, at or before the Closing, of each of the
following conditions:

          6A.  Representations and Warranties.  The representations and
               ------------------------------
warranties of the Company contained in Section 3, except for those stated to be
                                       ---------
made as of the date hereof, shall be true and correct in all material respects
at and as of the Closing as though then made, except to the extent of changes
caused by the transactions expressly contemplated herein or in the Transaction
Documents.

          6B.  Performance.  The Company shall have performed and complied with
               -----------

         1. EMPLOYMENT TERM AND DUTIES

                  1.1. EMPLOYMENT TERM. The Company shall employ Employee, and
Employee shall perform services for the Company, for the period commencing on
the Closing (as defined in the Merger Agreement) of the merger pursuant to the
Merger Agreement (the "Hire Date") and continuing for a period of fourteen (14)
months (the "Initial Term") unless terminated by Employee as set forth in

either party provides the other with written notification of its desire to
terminate the employment relationship no less than thirty (30) days prior to the

This Agreement (except as otherwise provided herein) and Employee's employment
hereunder, will automatically terminate on the fourth (4th) anniversary of the
Hire Date.

         1.2. DUTIES. Employee shall serve as a member of the Company's
Executive Management Committee. Employee shall perform all reasonable duties
assigned by the Company consistent with those assigned to other employees of the
Company possessing a comparable position. Employee understands and agrees that
his employment with the Company may require travel and overnight stays ("Travel
Assignments"), and Employee agrees to accept all Travel Assignments reasonably
assigned by the Company. Unless otherwise agreed upon by the Company, during the
Employment Term, the Employee shall devote all of his normal business time to
the performance of his duties to the Company and Employee shall diligently
perform his duties to further the interests of the Company.

         1.3. COMPENSATION AND BENEFITS.

                  1.3.1 BASE SALARY. In consideration of the services rendered
to the Company hereunder by the Employee and the Employee's covenants hereunder,
including but not limited to, his covenants under Sections 3 and 5 below, and
under the Company's Confidentiality, Proprietary Information and Inventions
Agreement, the Company shall, during the Employment Term, pay the Employee a
salary at the annual rate of One Hundred Fifty Thousand Dollars ($150,000) (the
"Base Salary"). The Base Salary shall be payable in accordance with the normal
payroll practices of the Company then in effect. The Base Salary and all other
forms of compensation paid to the Employee hereunder shall be subject to all
applicable taxes required to be withheld by the Company pursuant to federal,
state or local law. The Employee shall be solely responsible for income taxes
imposed on the Employee by reasons of any cash or non-cash compensation and
benefits provided by this Agreement.

                  1.3.2 TARGET BONUS. Employee will be entitled to an annual
Target Bonus of Three Hundred Fifty Thousand Dollars ($350,000) based upon
Employee's achievement of goals established by the Company, of which One Hundred
Fifty Thousand Dollars ($150,000) shall be guaranteed during the first year of
the Agreement.

                  1.3.3 BENEFITS PACKAGE. Employee shall be entitled to receive
such employee benefits as may be in effect from time to time as are afforded to
other comparable employees of the Company. For purposes of determining
eligibility and entitlement to benefits, Employee's date of hire will be
considered to be his hire date by Target, to the extent permissible by law.

                        Employee shall be provided with reimbursement (on a
basis that is "grossed up" for taxes) for term life insurance coverage in the
amount of $1.5 million and long term disability coverage in the amount of
$500,000 per year, both commencing on the Hire Date.

                  1.3.4 STOCK OPTIONS. Subject to approval by the Company's
Board of Directors, the Company shall grant to Employee within sixty (60) days
after Closing, in accordance with the terms of the Company's Stock Option Plan,
an option to purchase a total of Two Hundred Twenty Thousand (220,000) shares of
the Company's common stock (the "Option") at a grant price equal to the fair
market value of the Company's common stock on the

                                       2
<PAGE>   3

date of grant. The Option shall vest in four (4) equal installments as follows:
twenty-five percent (25%) upon Employee's completion of one (1) year of
employment with the Company and the remaining seventy-five percent (75%) in
twelve (12) equal installments upon Employee's completion of each three (3)
month period of employment thereafter. The Option shall be subject to the
Company's Stock Option Plan and form stock option documents. In addition,
Employee's shares of Target common stock and/or options to purchase shares of
Target common stock will be converted to shares of Company common stock and/or
options to purchase shares of Company common stock pursuant to the terms of the
Merger Agreement.

                  1.3.5 VACATION. Employee shall be entitled to vacation each
fiscal year in accordance with the vacation policies of the Company in effect
for other comparable employees of the Company. For purposes of determining
eligibility and entitlement to vacation, Employee's date of hire will be
considered to be his hire date by Target.

                  1.3.6 EXPENSES. The Company shall, upon receipt from the
Employee of signed and itemized lists of expenditures with supporting receipts
to the extent required by applicable income tax regulations and the Company's
reimbursement policies, reimburse the Employee for all out-of-pocket business
expenses reasonably incurred by the Employee in connection with his employment
hereunder.

                  1.3.7 TRAVEL. The Company agrees to reimburse Employee for
first class travel in connection with Employee's Travel Assignments.

                  1.3.8 ACCELERATION OF TARGET OPTIONS. Employee agrees to waive
all rights (if any) to acceleration of unvested options to purchase Target stock
("Target Option") contained in any agreement, stock option agreement, or any
other document, including but not limited to his offer letter dated April 5,
1999 (the "Offer Letter"), that grants Employee Target Options prior to Closing,
including, but not limited to, those Target Options granted on or about June 6,
2000. In connection therewith, Employee expressly acknowledges, understands and
agrees that he will not receive any accelerated vesting of Target or Company
options granted to Employee prior to Closing, including, but not limited to,
those Target Options granted on or about June 6, 2000. Employee further agrees
that his offer letter from Target dated April 5, 1999 shall cease to be
effective on the Closing and shall from the date of this Agreement cease to
govern in any way the effect of the Transaction on Employee's options to acquire
Target stock. Accordingly, this Agreement shall be the sole source of any
provision for the acceleration of vesting of Target Options as a result of or
following the Transaction, and the following are conditions of such vesting:
Each of Employee's Target Options from all option grants made by Target to
Employee prior to Closing, including, but not limited to, those Target Options
granted on or about June 6, 2000, will continue to vest in accordance with the
original vesting schedule for so long as Employee is employed by the Company.
Upon termination of employment for any reason, fifty percent (50%) of each of
Employee's unvested Target Options as of the date of termination shall become
fully vested.

agrees that his employment with the Company is contingent upon signing the
Company's Confidentiality, Proprietary Information and Inventions Agreement,
which is attached hereto as Exhibit A, prior to beginning work for the Company.

                  3. NON-COMPETITION AND NON-INTERFERENCE. In consideration of
the Company's entering in this Agreement, the Merger Agreement, and purchasing
all of Employee's outstanding shares of stock in Target, and providing the Base
Salary and other benefits to the Employee, and in consideration of the Company's
promise to provide Employee with its confidential and proprietary information

consideration, the receipt and sufficiency of which are hereby acknowledged by
Employee, the Employee covenants as follows:

         3.1. NON-COMPETITION.

Employee will not engage in any employment, business, or activity that is in any
way competitive with the Business, and Employee will not assist any other person

                       (iii) For purposes of this Agreement "Business" shall
mean the business of Aspect Development, Inc. and those portions of the
Company's business in which Employee participates.

                  3.2. NO DIVERSION OF OTHERS. During the Employment Term and
for one (1) year from the date that Employee's employment with the Company is
terminated, for any reason, the Employee shall not, either for himself or for
any other person, firm, corporation or other entity, directly or indirectly, or
by action in concert with others:

                       (i) directly or indirectly,  individually  or on behalf
of any other person, firm, partnership, corporation, or business entity of any
type, solicit, assist or in any way encourage any current employee or consultant
of the Company or any subsidiary of the Company to terminate his or her
employment relationship or consulting relationship with the Company or
subsidiary nor will Employee solicit the employment services of any former
employee of the Company or any subsidiary of the Company whose employment has
been voluntarily terminated for less than six (6) months; or

                       (ii) divert or take away or attempt  to divert or take
away, or solicit or attempt to solicit, any existing or potential customer of

the Employee or which became known by the Employee prior to the date hereof)
with the purpose of obtaining such person as an employee or customer for a
business competitive with the Company's business.

                  3.3. ORGANIZING COMPETITIVE BUSINESS. Without limiting any of
the other provisions contained in this Section 3, during the Employment Term and
any period during which Employee receives any severance payment, the Employee
shall not undertake planning for or organization of any business competitive
with the Company, or conspire with agents, employees, consultants or other
representatives of the Company for the purpose of organizing any such
competitive business.

         4. INJUNCTIVE RELIEF AND ADDITIONAL REMEDY

                  The Employee acknowledges and agrees that any breach of the
terms of Section 3 above would result in irreparable injury and damage to the
Company for which the Company would have no adequate remedy at law; the Employee
therefore also acknowledges and agrees that in the event of such breach or any
threat of breach, the Company shall be entitled to an immediate injunction and
restraining order to prevent such breach and/or threatened breach and/or
continued breach by the Employee and/or any and all persons and/or entities
acting for and/or with the Employee, without having to prove damages, in
addition to any other remedies to which the Company may be entitled at law or in
equity. The terms of this paragraph shall not prevent the Company from pursuing
any other available remedies for any breach or threatened breach hereof,
including but not limited to the recovery of damages from the Employee.

the Employee is not bound by or subject to any contractual or other obligation
that would be violated by his execution or performance of this Agreement,
including, but not limited to, any non-competition agreement presently in
effect, and (ii) the Employee is not subject to any pending or, to the
Employee's knowledge, threatened claim, action, judgment, order or investigation

Agreement and continue in full force and effect as is necessary or appropriate
to enforce the covenants and agreements of the Employee in Section 3. The
existence of any claim or cause of action by the Employee against the Company,
whether predicated on this Agreement or otherwise, shall not constitute a
defense to the enforcement by the Company of the covenants and agreements of
Section 3 above.
