         8.   EXPENSES.  The Company shall reimburse the Employee for all
reasonable expenses incurred in connection with his duties on behalf of the
Company, provided that the Employee shall keep, and present to the Company,
records and receipts relating to reimbursable expenses incurred by him. Such
records and receipts shall be maintained and presented in a format, and with
such regularity, as the Company reasonably may require in order to
substantiate the Company's right to claim income tax deductions for such
expenses. Without limiting the generality of the foregoing, the Employee
shall be entitled to reimbursement for any business-related travel,
business-related entertainment whether at his residence or otherwise, and
other costs and expenses reasonably incident to the performance of his duties

but shall exclude office space reimbursement.

         9.   TERMINATION OF EMPLOYMENT FOR CAUSE.  Notwithstanding the
provisions of Paragraph 2 of this Agreement, the Employee's employment (and
all of his rights and benefits under this Agreement) shall terminate
immediately and without further notice upon the happening of any one or more
of the following events:

              A.  The Employee has been or is guilty of (i) a criminal
offense involving moral turpitude, (ii) criminal or dishonest conduct
pertaining to the business or affairs of the Company (including, without
limitation, fraud and misappropriation), (iii) any act or omission the
intended or likely consequence of which is material injury to the Company's
business, property or reputation, which act or omission continues uncured for
a period of ten (10) days after the Employee has received written notice from
the Board of Directors, and (iv) gross negligence or willful misconduct which
continues uncured for a period of ten (10) days after the Employee has
received written notice from the Board of Directors;

              B.  The Employee persists, for a period of ten (10) days after
written notice from the Board of Directors, in a course of conduct reasonably
determined by the Board of Directors to be in material violation of his
duties to the Company under this Agreement or otherwise in violation of the
covenants, agreements or obligations under the terms of this Agreement;

              C.  The Employee's death; or

              D.  The continuous and uninterrupted inability to perform the
Employee's duties on behalf of the Company, by reason of accident, illness,
or disease, for a period of sixty (60) days from the first day of such
inability to perform his duties.

         Subsections A, B, C & D of this Section 9 are hereinafter referred
to collectively and individually as "Cause". In the event of a termination
for Cause, the Company shall pay the Employee his base salary through the
effective date of the employment termination, and the Employee shall
immediately thereafter forfeit all rights and benefits (other than vested
benefits), including but not limited to any right to compensation pursuant to
Section 4 or 5 of this


                                     -3-
<PAGE>

          Agreement, he would otherwise have been entitled to receive under
this Agreement. The Company and the Employee thereafter shall have no further
obligations under this Agreement except as otherwise provided in Sections 12,
13 and 14 of this Agreement.

         10.      CHANGE OF CONTROL; TERMINATION OF EMPLOYMENT BY THE COMPANY
WITHOUT CAUSE.  Notwithstanding the provisions of Section 2 of this
Agreement, the Board of Directors may terminate the Employee's employment at
any time, for reasons other than for Cause by notifying the Employee in
writing of such termination. If (A) the Employee is terminated pursuant to
this Section 10 for reasons other than for Cause, or (B) if a Change of
Control (as defined below) occurs and, within two (2) years thereafter, the
Employee is terminated without Cause, or the Employee's duties and
responsibilities are materially changed and the Employee determines to
terminate his employment, the Company shall pay the Employee, in a lump sum,
(i) an amount equal to two (2) year's worth of his base salary at the rate in
effect immediately prior to the date of termination but, in the case of item
(B), less the amount of base salary the Employee has received since the
Change of Control and (ii) the unpaid balance of any deferred compensation
owed to the Employee. Employee shall immediately thereafter forfeit all
rights and benefits (other than vested benefits), including but not limited
to any right to compensation pursuant to Section 4 or 5 of this Agreement he
would otherwise have been entitled to receive under this Agreement.
Notwithstanding the foregoing, should the Board of Directors terminate the
Employee without cause all unvested options shall immediately accelerate. The
Company and the Employee thereafter shall have no further obligations under
this Agreement except as otherwise provided in Sections 12, 13 and 14 of this
Agreement.

         For purposes of this Agreement, a "CHANGE IN CONTROL" shall be
deemed to have occurred if, in a single transaction or series of transactions,
(a) the Company merges or consolidates with another entity (other than an
affiliated entity) and the Company is not the surviving entity, (b) the
Company sells substantially all of its assets to any person (other than an to
an affiliated entity) or (c) the Company sells more than fifty percent (50%)
of its capital stock to another person or entity.

         11.      TERMINATION OF EMPLOYMENT BY THE EMPLOYEE.  Notwithstanding
the provisions of Section 2 of this Agreement, the Employee may terminate
this Agreement at any time by giving the Board of Directors written notice of
his intent to terminate, delivered at least sixty (60) days prior to the
effective date of such termination.

         Upon expiration of the sixty (60) day notice period (or such earlier
date as may be approved by the Board of Directors), the termination by the
Employee shall become effective. Upon the effective date the Employee shall
immediately thereafter forfeit all rights and benefits (other than vested
benefits), including but not limited to any right to compensation pursuant to
Section 4 or 5 of this Agreement, he would otherwise have been entitled to
receive under this Agreement. The Company and the Employee thereafter shall
have no further obligations under this Agreement except as otherwise provided
in Sections 12, 13 and 14 of this Agreement.

         This Section 11 shall not apply to a termination by the Employee
following a Changer of Control, as described in Section 10.

                                     -1-

         12.      NON-COMPETITION.  The Employee and the Company recognize
that due to the nature of his employment, and his relationship with the
Company, the Employee has had and will have access to, and has acquired and
will acquire, and has assisted and will assist in developing, confidential
and proprietary information relating to the business and operations of the
Company including, without limitation, information with respect to its
present and prospective services, technologies, systems, clients, customers,
agents, and sales and marketing methods. The Employee acknowledges that such
information has been and will be of central importance to the Company's
business and that disclosure of it to or its use by others could cause
substantial loss to the Company. The Employee and the Company also recognize
that an important part of the Employee's duties will be to develop good will
for the Company through his personal contact with the Company's clients, and
that there is a danger that this good will, a proprietary asset of the
Company, may follow the Employee if and when his relationship with the
Company is terminated.

                  A.       The Employee agrees that, during the term of his
employment with the Company, and for a period of one (1) year after the
termination of his employment for any reason whatsoever (including the
non-renewal of this Agreement by either party):

                           (i)    The Employee will not directly or
                  indirectly, in any jurisdiction where the Company is
                  operating on the date of such termination, whether as a
                  partner, proprietor, employee, consultant, agent or
                  otherwise, participate or engage in any business that
                  competes with, restricts, or interferes with the business
                  of the Company including but not limited to working with
                  any of the following companies without the prior written
                  consent of the Company:

                           a.     Northern Light

                           b.     dowjones.com

                           c.     office.com

                           d.     Lexis Nexis

                           e.     Hoovers

                           f.     Excite

                           (ii)   The Employee will not directly or
                  indirectly (for his own account, or for the account of
                  others) interfere with, solicit, or accept for himself, his
                  benefit, or for anyone other than the Company, any of the
                  clients or customers of the Company, at the time of said
                  termination, or any potential clients or customers
                  solicited or being solicited by the

                                     -2-

<PAGE>

                  Company at the time of such termination or within the
                  period one (1) year prior thereto, or perform any services
                  of any competitive nature in connection with said clients
                  or customers for anyone other than the Company.

                           (iii)  The Employee further agrees that he shall
                  not, at any time, directly or indirectly, urge any client
                  (or customer) or potential client (or potential customer)
                  of the Company to discontinue business, in whole or in
                  part, or not to do business, with the Company.

                           (vi)   The Employee further agrees that he shall
                  not, at any time, directly or indirectly, solicit, hire or
                  arrange to hire any person who at the time of such hire or
                  within six (6) months prior to the time of such hire was an
                  employee of the Company, or for himself or for any business
                  entity with which he may be, or may be planning to be,
                  affiliated or associated with, or otherwise interfere with
                  the retention of employees that the Company desires to
                  retain as such.

                  B.       The Employee expressly acknowledges and agrees (i)
that the restrictions set forth herein are reasonable, in terms of scope,
duration, geographic area, and otherwise, (ii) that the protections afforded
to the Company hereunder are necessary to protect its legitimate business
interests, and (iii) that the agreement to observe such restrictions form a
material part of the consideration for this Agreement and the Employee's
employment by the Company.

         13.      OWNERSHIP OF INFORMATION, IDEAS AND PRODUCTS.  The Employee
agrees that, during the term of his employment with the Company, any
invention, modification, discovery, design, development, improvement,
process, software program, work of authorship, documentation, formula, data,
technique, know-how, secret or intellectual property right whatsoever or any
interest therein (whether or not patentable or registrable under copyright or
similar statutes or subject to analogous protection) (herein called
"DEVELOPMENTS") that he develops or conceives, individually or in
conjunction with others, shall be and remain the sole and exclusive property
of the Company and that immediately upon the termination of his employment
he shall deliver all of the foregoing, and all copies or reproductions
thereof, to the Company, at its main office. If at any time or times during
his employment with the Company the Employee shall (either alone or with
others) make, conceive, discover or reduce to practice any Development that
(a) relates to the business of the Company or any customer of or supplier to
the Company or any of the products or services being developed, manufactured
or sold or developed by the Company or which may be used in relation
therewith, (b) results from tasks assigned to the Employee by the Company or
(c) results from the use of premises or personal property (whether tangible
or intangible) owned, leased or contracted for by the Company, such
Developments and the benefits thereof shall immediately become the sole and
absolute property of the Company and its assigns, and the Employee shall
promptly disclose to the Company (or any persons designated by it) each such
Development and hereby assign any rights Employee

                                     -3-


<PAGE>

may have or acquire in the Developments and benefits and/or rights resulting
therefrom to the Company and its assigns without further compensation and
shall communicate, without cost or delay, and without publishing the same,
all available information relating thereto (with all necessary plans and
models) to the Company.

          Upon disclosure of each Development to the Company, Employee will,
during his employment and at any time thereafter, at the request and cost of
the Company, sign, execute, make and do all such deeds, documents, acts and
things as the Company and its duly authorized agents may reasonably require:

              (a)  to apply for, obtain and vest in the name of the Company
          alone (unless the Company otherwise directs) letters patent,
          copyrights or other analogous protection in any country throughout the
          world and when so obtained or vested to renew and restore the same;
          and

              (b)  to defend any opposition proceedings in respect of such
          applications and any opposition proceedings or petitions or
          applications for evocation of such letters patent, copyright or
          other analogous protection.

    If the Company is unable, after reasonable effort, to secure Employee's
signature on any letters, patent, copyright or other analogous protection
relating to a Development, whether because of his physical or mental
incapacity or for any other reason whatsoever, Employee hereby irrevocably
designate and appoint the Company and its duly authorized officers and agents
as his agent and attorney-in-fact, to act for and in my behalf and stead to
execute and file any such application or applications and to do all other
lawfully permitted acts to further the prosecution and issuance of letters
patent, copyright or other analogous protection thereon with the same legal
force and effect as if executed by Employee.

    14.  CONFIDENTIAL INFORMATION.  The Employee agrees that, during the term
of his employment with the Company, and for a period of two (2) years after
the termination of his employment for any reason whatsoever, he shall not
disclose to any person or use the same in any way in direct or indirect
competition with the Company, other than in the discharge of his duties under
this Agreement in connection with the business of the Company, any trade
secrets or confidential or proprietary information of the Company, including,
without limitation, any information or knowledge relating to (i) trade
secrets, inventions, products, designs, methods, know-how, techniques,
systems, processes, software programs, works of authorship, projects, plans,
proposals, business, finances, operations or internal structure of the
Company, (ii) the clients (or customers) or potential clients (or potential
customers) of the Company, (iii) any method and/or procedure (such as
records, programs, systems, correspondence, or other documents), relating or
pertaining to the foregoing, or (iv) the Company's business, which
information or knowledge the Employee shall have obtained during the term of
this Agreement. Further, upon leaving the employ of the Company for any
reason whatsoever, the Employee shall not take with him, without prior
written consent of the Company, any documents, forms, or other reproductions
of any data or any information relating to or pertaining to the Company, any


                                      -4-

<PAGE>

clients (or customers) or potential clients (or potential customers) of the
Company, or any other confidential information or trade secrets.

    15.  ENTIRE AGREEMENT; AMENDMENTS, OTHER AGREEMENTS.  This Agreement
contains the entire understanding of the Employee and the Company with
respect to employment of the Employee and supersedes any and all prior
understandings, written or oral. This Agreement may not be amended, waived,
discharged or terminated orally, but only by an instrument in writing
executed by the Company and the Employee.

    16.  MISCELLANEOUS.

         A.  Any notices required by this Agreement shall (i) be made in
writing and mailed by certified mail, return receipt requested, with adequate
postage prepaid; (ii) be deemed given when so mailed; (iii) be deemed
received by the addressee within ten (10) days after given or when the
certified mail receipt for such mail is executed, whichever if earlier; and
(iv) in the case of the Company, be mailed to its principal office, or in the
case of the Employee, be mailed to the last address that the Employee has
given to the Company.

         B.  This Agreement shall be binding upon and inure to the benefit
of, the parties, their successors, assigns, personal representatives,
distributees, heirs, and legatees.

         C.  This Agreement shall be governed by, and construed and enforced
in accordance with, the laws of the State of Maryland, without giving effect
to the principles of conflicts of law thereof. For the purpose of expediting
the resolution of any such claim or dispute, the parties hereby waive trial
by jury.

         D.  Any failure by the Company to insist upon strict compliance with
any term or provision of this Agreement, to exercise any option, to enforce
any right, or to seek any remedy upon any breach by the Employee shall not
affect, or constitute a waiver of, the Company's right to insist upon such
strict compliance, exercise such option, enforce such right, or seek such
remedy with respect to such breach or any prior, contemporaneous, or
subsequent breach. No custom or practice of the Company at variance with any
provision of this Agreement shall affect or constitute a waiver of, the
Company's right to demand strict compliance with all provisions of this
Agreement.

         E.  Any provision of this Agreement which is prohibited or
unenforceable in any jurisdiction shall, as to such jurisdiction, be deemed
severable from the remainder of this Agreement, and the remaining provisions
contained in this Agreement shall be construed to preserve to the maximum
permissible extent the intent and purposes of this Agreement. Any such
prohibition or unenforceability in any jurisdiction shall not invalidate or
render unenforceable such provision in any other jurisdiction.

         F.  In the event that the Employee violates the provisions of
Sections 12, 13 or 14 above, upon notice from the Company informing him of
the nature of such violation, the


                                      -5-

<PAGE>

Employee shall immediately terminate any actions which constitute such
violation. The existence of this right shall not preclude any other rights
and remedies at law or in equity which the Company may have.

         G.  It is recognized that damages in the event of breach of any
provision of Sections 12, 13 or 14 above by the Employee would be difficult,
if not impossible, to ascertain, and it is therefore agreed that the Company,
in addition to and without limiting any other remedy or right it may have,
shall have the right to an injunction or other equitable relief in any court
of competent jurisdiction, enjoining any such breach; and the Employee hereby
waives any and all defenses he may have on the ground of the lack of
jurisdiction or competence of the court to grant such an injunction or other
equitable relief. The existence of this right shall not preclude any other
rights and remedies at law or in equity which the Company may have.

      IN WITNESS WHEREOF, the parties hereto have duly executed this
Agreement as of the day and year first hereinabove written.
