          (e)  Interpretation.  When a reference is made in this Agreement to
               --------------
Sections, such reference shall be to a Section to this Agreement unless
otherwise indicated. The headings contained in this Agreement are for reference
purposes only and shall not affect in any way the meaning or interpretation of
this Agreement. Wherever the words "include", "includes" or "including" are used
in this Agreement, they shall be deemed to be followed by the words "without
limitation."

     The parties acknowledge and agree that:  (i) each party to this Agreement
and its counsel reviewed and negotiated the terms and provisions of this
Agreement and have contributed to its revision; (ii) the rule of construction to
the effect that any ambiguities are resolved against the drafting party shall
not be employed in the interpretation of this Agreement; and (iii) the terms and
provisions of this Agreement shall be construed fairly as to both parties
hereto, regardless of which party was generally responsible for the preparation
of this Agreement or any provision hereof.

          (f)  Counterparts.  This Agreement may be executed in two or more
               ------------
counterparts, all of which shall be considered one and the same agreement, and
shall become effective when two or more of the counterparts have been signed by
each of the
<PAGE>

                                      -10-

parties and delivered to the other party, it being understood that each party
need not sign the same counterpart.

          (g)  Entire Agreement; No Third-Party Beneficiaries.  This Agreement
               ----------------------------------------------
(including the documents and instruments referred to herein) constitutes the
entire agreement and supersedes all prior agreements and understandings, both
written and oral, among the parties with respect to the subject matter hereof
and is not intended to and does not confer upon any Person other than the
parties hereto any rights or remedies hereunder.

          (h)  Governing Law.  This Agreement shall be construed in accordance
               -------------
with and governed in all respects, including validity, interpretation and
effect, by the law of the State of Delaware without giving effect to the
principles of conflicts of laws thereof.

          (i)  Consent to Jurisdiction; Consent to Service.  IN THE EVENT OF ANY
               -------------------------------------------
LITIGATION, CLAIM OR OTHER LEGAL PROCEEDING WITH RESPECT TO ANY MATTER
PERTAINING TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY, THE
PARTIES HERETO HEREBY WAIVE THE RIGHT TO A TRIAL BY JURY. THE PARTIES HERETO
HEREBY READILY CONSENT TO THE NON-EXCLUSIVE JURISDICTION AND VENUE OF THE COURTS
OF THE STATE OF DELAWARE AND ANY FEDERAL COURT LOCATED IN THE STATE OF DELAWARE
IN CONNECTION WITH ANY LITIGATION ARISING OUT OF OR RELATING TO THIS AGREEMENT
OR THE TRANSACTIONS CONTEMPLATED HEREBY. THE PARTIES HERETO HEREBY WAIVE
PERSONAL SERVICE OF ANY PROCESS IN CONNECTION WITH ANY SUCH LITIGATION AND AGREE
THAT SERVICE THEREOF MAY BE MADE BY CERTIFIED OR REGISTERED MAIL ADDRESSED TO OR
BY PERSONAL DELIVERY TO ANOTHER PARTY TO THIS AGREEMENT AT SUCH OTHER PARTIES'
ADDRESS SPECIFIED IN SECTION 10(d).

          (j)  Severability. If any term or other provision of this Agreement is
               ------------
invalid, illegal or incapable of being enforced by any rule of law or public
policy, all other conditions and provisions of this Agreement shall nevertheless
remain in full force and effect. Upon such determination that any term or other
provision is invalid, illegal or incapable of being enforced, the parties hereto
shall negotiate in good faith to modify this Agreement so as to effect the
original intent of the parties as closely as possible to the fullest extent
permitted by applicable law in an acceptable manner to the end that the
transactions contemplated hereby are fulfilled to the extent possible. If no
such agreement is reached between the parties, the term or provision which is
determined to be invalid, illegal or incapable of being enforced shall
nonetheless be enforced to fulfill the intent of the parties to the extent
legally permissible.

          (k)  Equitable Relief. In the event of any breach or threatened breach
               ----------------

jurisdiction, without posting a
<PAGE>

                                      -11-

bond or other security of any kind whatsoever, it being agreed that any breach
or threatened breach of this Agreement would cause Parent irreparable injury and
that money damages alone would not provide an adequate remedy.

     11.  Confidentiality; Public Announcements. Each Stockholder recognizes
          -------------------------------------
that successful consummation of the Transactions may be dependent upon
confidentiality with respect to the matters referred to herein. In this
connection, pending public disclosure of the Transactions by the Parent, the

this Agreement (other than such person's counsel and advisors, if any) without
the prior written consent of the Parent and the Company, except for filings
required pursuant to the Exchange Act and the rules and regulations thereunder
or as required by law.
