                             EMPLOYMENT AGREEMENT

DATE:        November 5, 1999

PARTIES:     eCollege.com, a Delaware corporation (the "Company")

             Robert Haimes, a resident of Colorado (the "Employee")

RECITAL:

The Company is engaged in the business of online web production, online
education and online training. The Company desires to employ and retain the
unique experience, abilities, and services of Employee as Vice President of
Marketing in the Company's office in Denver, Colorado.

AGREEMENT:

        The parties agree as follows:

1)  EMPLOYMENT

    a)  Duties.  Company shall employ Employee as Vice President of Marketing.
        ------
        Employee accepts employment with the Company on the terms and conditions
        set forth in this Agreement, and agrees to devote his full time and
        attention (reasonable periods of illness excepted) to the performance of
        his duties under this Agreement. In general, such duties shall consist
        of the duties and responsibilities described on Schedule A to this
        Agreement. In performing such duties, Employee shall be subject to the
        direction and control of the Vice President of the Employee's
        Department, the Executive Committee and the President of the Company.
        Employee further agrees that in all aspects of such employment, Employee
        shall comply with the policies, standards, and regulations of the
        Company established from time to time, and shall perform his duties
        faithfully, intelligently, to the best of his ability, and in the best
        interest of the Company. The devotion of reasonable periods of time by
        Employee for personal purposes or charitable activities shall not be
        deemed a breach of this Agreement, provided that such purposes or
        activities do not materially interfere with the services required to be
        rendered to or on behalf of the Company; however, any outside business
        activities that are not first submitted in writing to the President of
        the Company, and approved in writing by the President shall be deemed a
        breach of this Agreement.

    b)  Term.  Employment of the Employee shall begin on November 5, 1999 and
        ----
        shall end on the date of termination pursuant to Section 5 of this
        Employment Agreement (the "Agreement"). The term of this Agreement shall
        commence on November 5, 1999 and terminate on October 31, 2000 (the
        "Initial Term"); the term of this Agreement shall be extended
        automatically for successive periods of one (1) year each ("Renewal
        Term") after the expiration of the Initial Term and any subsequent
        Renewal Term, unless either (i) the Company provides the Employee, or
        the Employee provides the Company, with written notice to the contrary
        at least thirty (30) days prior to the end of the Initial Term or any
        Renewal Term or (ii) the Employee is no longer employed by the Company
        at the end of the Initial Term or the Renewal Term, as appropriate.

2)  NON SOLICITATION; CONFIDENTIALITY

    a)  Nonsolicitation.  During the term of this Agreement and for a period of
        ---------------
        twelve (12) months after the termination of this Agreement, Employee
        shall not, within the United States or Canada, directly or indirectly:
        (1) solicit or accept if offered to his, with or without solicitation,
        on his own behalf or on behalf of any other person, the services of any
        person who is an employee of the Company, nor solicit any of the
        Company's employees to terminate employment with the Company, nor agree
        to hire any employee of the Company into employment with himself or any
        company, individual or other entity; (2) directly or indirectly,
        contact, solicit or direct any person, firm, or corporation to contact
        or solicit, any of the Company's customers, prospective customers, or
        business brokers for the purpose of selling or attempting to sell, any
        products and/or services that are the same as, or similar to, the
        products and services provided by the Company to its customers during
        the term hereof; or (3) disclose the identity of any such business
        brokers, customers, or prospective customers, or any part thereof, to
        any person, firm, corporation, association, or other entity for any
        reason or purpose whatsoever.

    b)  Confidentiality.  Employee acknowledges and agrees that all product
        ---------------
        specifications, product planning information, lists of the Company's
        customers and suppliers, marketing plans, financial information, and
        other Company data related to its business ("Confidential Information")
        are valuable assets of the Company. Except for information that is a
        matter of public record, Employee shall not, during the term of this
        Agreement or after the termination of employment with the Company,
        disclose any Confidential Information to any person or use any
        Confidential Information for the benefit of Employee or any other
        person, except with the prior written consent of the Company.

    c)  Ideas, Inventions.  The Employee recognizes and agrees that all ideas,
        -----------------
        inventions, enhancements, plans, writings, and other developments or
        improvements (the "Inventions") conceived by the Employee, alone or with
        others, during the term of his employment, whether or not during working
        hours, that are within the scope of the Company's business operations or
        that relate to any of the Company's work or projects, are the sole and
        exclusive property of the Company. The Employee further agrees that (1)
        he will promptly disclose all Inventions to the Company and hereby
        assigns to the Company all present and future rights he has or may have
        in those Inventions, including without limitation those relating to
        patent, copyright, trademark or trade secrets; and (2) all of the
        Inventions eligible under the copyright laws are "work made for hire."
        At the request of and without charge to the Company, the Employee will
        do all things deemed by the Company to be reasonably necessary to
        perfect title to the Inventions in the Company and to assist in
        obtaining for the Company such patents, copyrights or other protection
        as may be provided under law and desired by the Company, including but
        not limited to executing and signing any and all relevant applications,
        assignments or other instruments.

        Notwithstanding the foregoing, the Company hereby notifies the Employee
        that the provisions of this Section 2)c) shall not apply to any
        Inventions for which no equipment, supplies, facility or trade secret
        information of the Company was used and which were developed entirely on
        the Employee's own time, unless (1) the Invention relates (i) to the
        business of the Company, or (ii) to actual or demonstrably anticipated
        research or development of the Company, or (2) the Invention results
        from any work performed by the Employee for the Company.

   d) Nondisparagement.  During the term of this Agreement and for a period of
      ----------------
      two years following the voluntary or involuntary termination of the
      Employee's employment, the parties shall not make any statements
      concerning the other party that would tend to diminish the esteem,
      respect, good will, or confidence in which that party is held by members
      of the community in which that party, or its officers, directors and
      employees, conduct their business affairs or that would provoke adverse or
      derogatory feelings or opinions in such members of those communities as to
      that party.

   e) Return of Documents and Computer Data.  Employee acknowledges and agrees
      -------------------------------------
      that all originals and copies of all computer data, records, reports,
      documents, lists, plans, drawings, memoranda, notes, and other
      documentation related to the business of the Company or containing any
      Confidential Information shall be the sole and exclusive property of the
      Company, and shall be returned to the Company upon the termination of
      employment with the Company or upon the written request of the Company.

   f) Injunction.  Employee agrees that it would be difficult to measure damage
      ----------
      to the Company from any breach by Employee of Section 2)a), 2)b), 2)c) or
      2)d) and that monetary damages would be an inadequate remedy for any such
      breach. Accordingly, Employee agrees that if Employee shall breach or take
      steps preliminary to breaching Section 2)a), 2)b), 2)c) or 2)d), the
      Company shall be entitled, in addition to all other remedies it may have
      at law or in equity, to an injunction or other appropriate orders to
      restrain any such breach, without showing or proving any actual damage
      sustained by the Company.

   g) No Release.  Employee agrees that the termination of employment with the
      ----------
      Company or the expiration of the term of this Agreement shall not release
      Employee from any obligations set forth herein pursuant to Section 2)a) -
      f).

      --------------
      a brief, general description of the Company's benefits. Employee agrees
      and acknowledges that the benefits provided by the Company may be changed
      or amended from time to time, and at any time, at the sole discretion of
      the Company.

4) COMPANY POLICIES

   a) General Policy Descriptions.  Employee has been provided with the
      ---------------------------

      Programs, Employee Referral Program and Smoke Free Work Environment as of
      November 5, 1999. Additional policies and standards of the Company will be

   a) At-Will Employment.  Employee agrees and acknowledges that, just as he has

      with the Company at any time for any reason.

   b) Severance.  The Company shall provide Employee with severance pay equal to
      ---------
      approximately one week of Employee's base salary, less any negative
      accrued vacation days, provided that the Employee's termination is either
      (i) voluntary termination where the Employee provides the Company with two
      weeks written notice of resignation or (ii) involuntary termination at any
      time beginning ninety (90) days after the date of this Agreement, and not
      pursuant to Section 5)c) of this Agreement.

   c) Immediate Termination.  The employment of Employee by the Company may be
      ---------------------
      terminated immediately in the sole discretion of the either the President,

      ------------------------------
      Company that there is no employment contract or any other contractual
      obligation to which Employee is subject, which prevents Employee from
      entering into this Agreement or from performing fully Employee's duties
      under this Agreement.

   b) Special Needs.  There are no special accommodations required to be made by
      -------------
      Company for Employee to perform his duties and responsibilities.

          the field of business law in accordance with the then current
          Commercial Arbitration Rules of the American Arbitration Association
          and judgment upon the award of the arbitrator may be entered in any
          court having jurisdiction thereof and any party to the arbitration

          any witness proposed by either party.

     iii) The parties agree that the arbitrator shall have no jurisdiction to
          consider evidence with respect to or render an award or judgment for
          punitive damages (or any other amount awarded for the purpose of
          imposing a penalty), incidental or consequential damages, except as
          authorized by statute.

     iv)  The arbitrator shall award all direct costs of the arbitration,
          including arbitrator's fees and arbitration filing fees according to
          the parties' ability to pay.

     v)   The arbitrator shall determine a schedule for the arbitration

                           ACKNOWLEDGMENT
                           --------------

     I acknowledge that I have received, read, and understood the Employment
Agreement, the Schedules attached thereto, and the Employee Benefits Handbook of
eCollege.com, (the "Company"). Further, I understand and agree to the following:

     1.  The Employment Agreement, the Schedules attached thereto, and the
Employee Benefits Handbook (the "Employment Documents") contain a brief summary
of some important Company guidelines and policies. Consequently, the Employment
Documents are not all-inclusive and do not include all guidelines and policies
which may affect my employment with the Company.

     2.  The Company may alter, amend, delete or add to any of the statements
contained in the Employment Documents, or any of its policies or guidelines, at
any time, with or without notice, and my continued employment with the Company
after any such deletion or addition constitutes acceptance.

     3.  No contract, agreement, understanding, course of dealing, practice, or
statement of any kind by any employee, supervisor, officer, director, or
representative of the Company shall be effective or binding upon the Company
unless it is in writing, refers to and names me personally, and is signed by me
and by an authorized Company representative.

     4.  Just as I have the right to terminate my employment with the Company at
any time for any reason, with or without cause and with or without notice, the
Company has the same right, and may terminate my employment with the Company at
any time for any reason, with or without cause, and with or without notice.

     5.  The Employment Documents provide for arbitration of any matter related
to my employment and any matter or claim between the Company any me. I
understand that by signing the Employment Agreement, I am waiving my rights to a
trial to a court or jury and to have any claim against the Company (including
claims relating to employment or termination) filed and heard in state or
federal court, and the Company has also waived its rights to have any claim
against me filed and heard in state or federal court. Instead, the Company and I
have agreed to have all disputes resolved by arbitration before the American
Arbitration Association.
