Remedies upon Breach.If the Employee breaches any of
the provisions of Section 1, Prism, MoSys and any corporation or other
entity to which a substantial part of the Business is transferred or which
otherwise succeeds to a substantial part of the Business (each a Beneficiary
and collectively, the Beneficiaries) shall have the following rights
and remedies, each of which rights and remedies shall be independent of the
others and severally enforceable, and each of which is in addition to, and not
in lieu of, any other rights and remedies available to any of the Beneficiaries
under law or in equity.  2


(a)  Specific Performance.  The right and remedy to
have the provisions of Section 1 specifically enforced by any court of
competent jurisdiction by way of an injunction or other legal equitable relief,
it being agreed that any breach of the covenants specified in Section 1
would cause irreparable injury to the Beneficiaries and that pecuniary
compensation would not afford adequate relief to the Beneficiaries, or it would
be extremely difficult to ascertain the amount of compensation which would
afford adequate relief.  Therefore, the
Employee agrees that, in the event of any such breach or threatened breach of Section 1,
the Beneficiaries will have the right to seek and obtain injunctive relief.  (b)  Accounting.  The right
and remedy to require the Employee, if he is in knowing breach of the
Agreement, to account for and pay over to the Beneficiaries any and all
compensation received by the Employee pursuant to his employment agreement as a
result of the termination of his employment with the Company, net gains or
other benefits received by the Employee as the result of any action
constituting a breach of this Agreement.  2.2  Severability of
Covenants.The Employee
acknowledges and agrees that the covenants contained in Section 1 are
reasonable and valid in duration and geographical scope and in all other
respects.  If any court determines that
any of such covenants, or any part thereof, is invalid or unenforceable in any
respect, such covenant shall not thereby be affected in any other respect and
shall be given full effect in all other respects.  If any court determines that any of such
covenants, or any part thereof, is unenforceable because of the duration or
geographical scope of such provision, the parties intend that such court shall
reduce the duration or geographical scope of such provision, as the case may
be, and, in its reduced form, enforce such provision.  The covenants of this Agreement are
independent of and separable from each other, and no covenant shall be affected
or rendered invalid or unenforceable by virtue of the fact that any other
covenant may be invalid or unenforceable in whole or in part for any reason.  2.3  Enforceability in
Jurisdictions; Governing Law.MoSys and the Employee
intend to and hereby confer nonexclusive jurisdiction to enforce this Agreement
upon the courts of any jurisdiction within the geographical scope of the
covenants set forth in Section 1. 
If the courts of any one or more of such jurisdictions hold any portion
of this Agreement unenforceable under the law applied by such court, it is the
intention of the parties that such determination not bar or in any way affect
the right of the Beneficiaries to the relief provided above in the courts of
any other jurisdiction within the geographical scope of the provisions of this
Agreement as to breaches of such provisions in such other respective
jurisdictions, such provisions as they relate to each jurisdiction being, for
this purpose, severable into diverse and independent covenants.  As to activities of the Employee in
California, this Agreement shall be governed by California law.  As to activities of the Employee outside
California, this Agreement shall be governed by the law of the jurisdiction in
which such activities are conducted.  2.4  Assignability.This
