    3. Exclusions.

         (a) The parties acknowledge that this Reciprocal Release does not
release any claims that the Dunn Group may have or assert against Ira Saul or
George J. Mercuro, Jr. as tort-feasors or otherwise concerning their role in the
formation or operation of Glacier LLC, a Virginia limited liability company.
This Release also does not release any claims (if any exist) that the Dunn Group
may have or assert against Ira Saul or George J. Mercuro, Jr. as tort-feasors or
otherwise concerning any aspect of their activities as former employees or
officers of STMS (except





that any and all claims against them relating to the formation or operation of
Mindshare Corporation are released, as provided above).

         (b) The parties acknowledge that this Reciprocal Release shall not
affect the validity or enforceability of debts owned by Glacier to the Bergman
Group which were incurred prior to August 1, 1997, and all interest accruing
forward from such debt.

         (c) The parties acknowledge that this Reciprocal Release shall not
affect the validity or enforceability of the representations, warranties,
covenants and obligations under the Stock Acquisition, Stock Option, Settlement,
and Reciprocal Release Agreement dated the date hereof among the parties hereto,

    4. Stipulated Amount. The parties agree and stipulate that the amount of the

the first refusal right set forth in Section 12.02(b) of the Operating Agreement
of Glacier.

    5. Law Governing. The laws of the Commonwealth of Virginia (except as to
conflicts of law) shall govern the validity, interpretation and enforcement of
this Reciprocal Release. The parties acknowledge that the parties concluded this
Reciprocal Release in Virginia, that part or all of the parties' performance
shall occur in Virginia, and that either the Federal District Court for the
Eastern District of Virginia, Alexandria Division, or the Circuit Court of
Fairfax County, Virginia shall have jurisdiction over any dispute directly or
indirectly related to any aspect of the parties' Reciprocal Release.

    6. Amendments and Waivers. No amendment of this Reciprocal Release shall
bind the parties unless they sign a written document containing the
modification.

this Reciprocal Release invalid or unenforceable, the court will enforce the
remaining provisions of this Reciprocal Release to the maximum extent permitted
by law. Further, if the court concludes that this Reciprocal Release has a
number of possible constructions, one of which would render this Reciprocal
Release void while the other interpretation would render the Reciprocal Release
enforceable, the parties intend the meaning that will render this Reciprocal
Release enforceable.

    8. Construction. The parties have participated jointly in negotiating and
drafting this Reciprocal Release. If an ambiguity or question of intent or
interpretation arises, no presumption or burden of proof shall arise favoring or
disfavoring any party by virtue of the authorship of any of the provisions of
this Reciprocal Release.

convenient reference and do not constitute a part of this Reciprocal Release.

more counterparts, each of which constitutes an original copy and all of which
