(d)  "For Cause" means a termination by the Company effected by a written notice
     of termination For Cause as a result of Executive's: (i) willful misconduct
     with regard to the Company or its business, assets or employees; (ii)
     refusal to follow the proper written direction of the Board of Directors of
     the Company (the "Board") or a more senior officer of the Company, provided
     that the foregoing refusal shall not be "For Cause" if in good faith

     prior to the Change in Control.

2. TERMINATION AFTER CHANGE IN CONTROL. The Executive shall be entitled to the
following benefits in the event a Change in Control shall occur and the
Executive's employment is terminated by the Company other than For Cause (other
than a termination resulting from a Disability) or the Executive terminates its
employment with the Company For Good Reason.

     A. Acceleration of Options. Notwithstanding anything to the contrary
contained in (a) any option or similar agreement between Executive and the
Company or (b) any stock option plan of the Company (including the Company's
1996 Stock Option Plan), in the event that a Change in Control shall occur and
Executive's employment is terminated by the Company other than For Cause (other

the transaction; and, (iii) without duplication of (i) or (ii) above the Company
shall arrange for the surviving or acquiring entity to grant to Executive
substitute options to purchase securities of the surviving or acquiring entity
in exchange for Executive's Options. The underlying securities of such
substitute options shall have a fair market value equal to the fair market value
of the securities subject to the Options (as determined by reference to the
value ascribed to the Company in the transaction which triggers Executive's
rights under this paragraph, as such value may be equitably adjusted by the
Board of Directors to take into account amounts paid or payable for
non-competition consulting and/or similar agreements entered into in connection
with the transaction). The substitute options shall be issued with an aggregate
exercise price equal to the aggregate exercise price of the securities subject
to the Options and with terms and conditions comparable to the terms and
conditions applicable to such Options (other than the terms and conditions
imposed by virtue of this Agreement).

     B. Severance. In the event that a Change in Control occurs and Executive's
employment is terminated by the Company other than For Cause (other than a
termination resulting from a Disability) during the two year period immediately
following the date of the Change in Control; or a Change in Control occurs and
Executive terminates Executive's employment with the Company For Good Reason
during the two year period following the date of the Change in Control, then the
Executive shall be entitled to the applicable: (i) Severance Compensation
payable in a lump sum cash amount within thirty (30) days of the effective date
of termination; and, (ii) health insurance coverage for Executive and his/her
dependents for a period of time equal to the Severance Period, to the extent
possible, on terms comparable to the terms of such coverage in effect on the
date of the Change in Control or the effective date of termination (whichever is
more favorable to Executive).

3. PROTECTED INFORMATION. The Executive hereby recognizes and acknowledges that
during the course of its employment by the Company, the Company will furnish,
disclose or make available to the Executive confidential or proprietary
information related to the Company's business, including, without limitation,
confidential or proprietary information with respect to the Company's
operations, processes, products, inventions, business practices, finances,
principals, vendors, suppliers, customers, potential customers, marketing
methods, costs, prices, contractual relationships, regulatory status,
compensation paid to employees or other terms of employment, that such
confidential or proprietary information has been developed and will be developed
through the Company's expenditure of substantial time and money, and that all
such confidential information could be used by the Executive and others to
compete with the Company. The Executive hereby agrees that all such confidential
or proprietary information shall constitute trade secrets, and further agrees to
use such confidential or proprietary information only for the purpose of
carrying out its duties with the Company and not to directly or indirectly,
disclose, deliver,

<PAGE>

publish or use such information except pursuant to section. No information
otherwise in the public domain (other than by an act of Executive in violation
hereof) shall be considered confidential. The Executive agrees that all
memoranda, notices, files, records, computer programs or similar repository and
other documents of or containing any such confidential or proprietary
information or trade secrets, made or compiled by the Executive during the
period of its employment or made available to him, shall be the Company's
property and shall be delivered to the Company upon its request therefor and in
any event upon the termination of the Executive's employment with the Company.
The parties hereby stipulate and agree that as between them the foregoing
matters are important, material and confidential proprietary information and
trade secrets and affect the successful conduct of the businesses of the Company
(and any successor or assignee of the Company). The restrictions in this Section
shall survive the termination or expiration of this Agreement and shall be in
addition to any restrictions imposed upon the Executive by statute or at common
law.

4. PROHIBITED SOLICITATION AND COMPETITION. The Executive hereby agrees, in
consideration hereunder and in view of the confidential position to be held by
the Executive hereunder, that at any time during Executive's employment with the
Company and for a period of time equal to the Severance Period following the
Executive's termination of employment, the Executive will not directly or
indirectly without the prior written consent of the Company's Board of
Directors: (i) engage in, or have any interest in, or manage or operate any
person, firm, corporation, partnership or business (whether as director,
officer, employee, agent, representative, partner, security holder, consultant
or otherwise) that engages in any business which then competes with any business
of the Company or any subsidiary anywhere in the world (each, a "Competitor")
(other than beneficial ownership of up to 5% of the outstanding voting stock of
a publicly traded company); or (ii) induce any employee of the Company or its
subsidiaries to terminate such employment or to become employed by any
Competitor. The restrictions in this Section shall survive the termination of
this Agreement and shall be in addition to any restrictions imposed upon the
Executive by statute or at common law.

     The parties hereby acknowledge that the restrictions in this Section have
been specifically negotiated and agreed to by the parties hereto and are limited
only to those restrictions necessary to protect the Company from unfair
competition. The parties hereby agree that in the event the agreement in this
Section shall be determined by any court of competent jurisdiction to be
unenforceable by reason of its extending for too great a period of time or over
too great a geographical area or by reason of its being too extensive in any
other respect, it will be interpreted to extend only over the maximum period of
time for which it may be enforceable, and/or over the maximum geographical area
as to which it may be enforceable and/or to the maximum extent in all other
respects as to which it may be enforceable, all as determined by such court in
such action. Each provision, paragraph and subparagraph of this Section is
separable from every other provision, paragraph, and subparagraph and
constitutes a separate and distinct covenant.

5. INJUNCTIVE RELIEF. The Executive hereby expressly acknowledges that any
breach or threatened breach by the Executive of any of the terms set forth in
Sections 3 and 4 of this Agreement may result in significant and continuing and
irreparable injury to the Company, the monetary value of which would be
difficult or impossible to establish and that the remedies at law for any such
breach or threatened breach will be inadequate. Therefore, the Executive agrees
that the Company shall be entitled to specific performance and injunctive relief
in a court of appropriate jurisdiction in addition to any other remedy that may
be available at law or in equity. The provisions of this Section shall survive
the Employment Term.

6. TERMINATION. Notwithstanding those Sections herein which specifically survive
termination of this Agreement, this Agreement shall terminate in the event that
Executive's employment with the Company shall terminate for any reason prior to
the date of a Change in Control.

<PAGE>

7. NO EFFECT ON OTHER RIGHTS. Nothing contained in this Agreement shall be
construed as limiting or otherwise adversely affecting any of the Executive's
rights under any other agreement or plan in effect as of the date hereof.

8. NO EMPLOYMENT AGREEMENT. It is understood and agreed between Executive and
Company that this Agreement is intended to provide only for certain rights in
the event of a Change in Control. This Agreement shall not be construed as a
contract of employment nor shall anything herein be construed as providing
employment to Executive for any fixed term. Executive acknowledges that he is an
employee at will and that both the Company and the Executive have the absolute
right to terminate the Executive's employment at any time.

9. BINDING EFFECT. This Agreement shall be binding upon and inure to the benefit
of the parties hereto and their respective successors, assigns, heirs, executors
and administrators. If any provision of this Agreement shall conflict with or be
contrary to any provision in any other agreement between the Executive and
Company, the terms and conditions of this Agreement shall control. Any
paragraph, sentence, phrase or other provision of this Agreement which is or
becomes in conflict with any applicable statute, rule or other law shall be
deemed, if possible, to be modified or altered to conform thereto or, if not
possible, to be omitted herefrom. If any provision of this Agreement shall be or
become illegal or unenforceable in whole or in part for any reason whatsoever,
the remaining provisions shall nevertheless be deemed valid, binding and
subsisting.

10. GOVERNING LAW. This Agreement has been negotiated and executed within the
State of New Jersey, and the validity, interpretation and enforcement of this
Agreement shall be governed by the laws of the State of New Jersey.

11. NOTICE. Notices authorized or required to be sent pursuant to this Agreement
shall be in writing and sent by personal delivery or postage prepaid, by
Certified or Registered Mail, return receipt requested, directed to the other
party at its address as may be designated by notice from time to time. Notices
to CommVault shall be addressed to the attention of the Chief Executive Officer.
Notice shall be deemed given on the date the envelope in which such notice is
enclosed, as provided above, is deposited for mailing in a mailbox or post
office.

12. HEADINGS. The headings of Sections in this Agreement are for convenience
only and form no part of this Agreement and shall not affect its interpretation.

     IN WITNESS WHEREOF, the parties have executed the Agreement as of the date
first above written.

COMMVAULT SYSTEMS, INC.

INDEMNITY AGREEMENT

This Indemnity Agreement (this "Agreement"), dated as of February __, 2004, is
made by and between CommVault Systems, Inc., a Delaware corporation (the
"Company"), and _________________, a director and/or officer of the Company (the
"Indemnitee").

RECITALS

     A. The Company is aware that competent and experienced persons are
increasingly reluctant to serve as directors or officers of corporations unless
they are protected by comprehensive liability insurance and/or indemnification,
due to increased exposure to litigation costs and risks resulting from their
service to such corporations, and due to the fact that the exposure frequently
bears no reasonable relationship to the compensation of such directors and
officers;

     B. Based upon their experience as business managers, the Board of Directors
of the Company (the "Board") has concluded that, to retain and attract talented
and experienced individuals to serve as officers and directors of the Company,
and to encourage such individuals to take the business risks necessary for the
success of the Company, it is necessary for the Company contractually to
indemnify officers and directors and to assume for itself maximum liability for
expenses and damages in connection with claims against such officers and
directors in connection with their service to the Company;

     C. Section 145 of the General Corporation Law of Delaware, under which the
Company is organized ("Section 145"), empowers the Company to indemnify by
agreement its officers, directors, employees and agents, and persons who serve,
at the request of the Company, as directors, officers, employees or agents of
other corporations or enterprises, and expressly provides that the
indemnification provided by Section 145 is not exclusive; and

     D. The Company desires and has requested the Indemnitee to serve or
continue to serve as a director or officer of the Company free from undue
concern for claims for damages arising out of or related to such services to the
Company.

NOW, THEREFORE, the parties hereto, intending to be legally bound, hereby agree
as follows:

1. DEFINITIONS.

     1.1 Agent. For the purposes of this Agreement, "agent" of the Company means
any person who is or was a director or officer of the Company or a subsidiary of
the Company; or is or was serving at the request of, for the convenience of, or
to represent the interest of the Company or a subsidiary of the Company as a
director or officer of another foreign or domestic corporation, partnership,
joint venture, trust or other enterprise or an affiliate of the Company. The
term "enterprise" includes any employee benefit plan of the Company, its
subsidiaries, affiliates and predecessor corporations.

     1.2 Expenses. For purposes of this Agreement, "expenses" includes all
direct and indirect

<PAGE>

costs of any type or nature whatsoever (including, without limitation, all
attorneys' fees and related disbursements and other out-of-pocket costs)
actually and reasonably incurred by the Indemnitee in connection with the
investigation, defense or appeal of a proceeding or establishing or enforcing a
right to indemnification or advancement of expenses under this Agreement,
Section 145 or otherwise; provided, however, that expenses shall not include
certain judgments, fines, ERISA excise taxes or penalties or amounts paid in
settlement of a proceeding.

     1.3 Proceeding. For the purposes of this Agreement, "proceeding" means any
threatened, pending or completed action, suit or other proceeding, whether
civil, criminal, administrative, investigative or any other type whatsoever.

     1.4 Subsidiary. For purposes of this Agreement, "subsidiary" means any
corporation of which more than 50% of the outstanding voting securities is owned
directly or indirectly by the Company, by the Company and one or more of its
subsidiaries or by one or more of the Company's subsidiaries.

2. AGREEMENT TO SERVE. The Indemnitee agrees to serve and/or continue to serve
as an agent of the Company, at the will of the Company (or under separate
agreement, if such agreement exists), in the capacity the Indemnitee currently
serves as an agent of the Company, faithfully and to the best of his ability, so
long as he is duly appointed or elected and qualified in accordance with the
applicable provisions of the charter documents of the Company or any subsidiary
of the Company; provided, however, that the Indemnitee may at any time and for
any reason resign from such position (subject to any contractual obligation that
the Indemnitee may have assumed apart from this Agreement), and the Company or
any subsidiary shall have no obligation under this Agreement to continue the
Indemnitee in any such position.

3. DIRECTORS' AND OFFICERS' INSURANCE. The Company shall, to the extent that the
Board determines it to be economically reasonable, maintain a policy of
directors' and officers' liability insurance ("D&O Insurance"), on such terms
and conditions as may be approved by the Board.

4. MANDATORY INDEMNIFICATION. Subject to Section 9 below, the Company shall
indemnify the Indemnitee:

     4.1 Third Party Actions. If the Indemnitee is a person who was or is a
party or is threatened to be made a party to any proceeding (other than an
action by or in the right of the Company) by reason of the fact that he is or
was an agent of the Company, or by reason of anything done or not done by him in
any such capacity, (a) against any and all expenses and liabilities of any type
whatsoever (including, but not limited to, judgments, fines, ERISA excise taxes
or penalties and amounts paid in settlement) actually and reasonably incurred by
him in connection with the investigation, defense, settlement or appeal of such
proceeding if he acted in good faith and in a manner he reasonably believed to
be in, or not opposed to, the best interests of the Company and, with respect to
any criminal action or proceeding, had no reasonable cause to believe his
conduct was unlawful; and

     4.2 Derivative Actions. If the Indemnitee is a person who was or is a party
or is threatened to be made a party to any proceeding by or in the right of the
Company to procure a judgment in its favor by reason of the fact that he is or
was an agent of the Company, or by reason of anything done or not done by him in
any such capacity, against any amounts paid in settlement of any such proceeding
and all expenses actually and reasonably incurred by him in connection with the
investigation, defense, settlement or appeal of such proceeding if he acted in
good faith

<PAGE>

and in a manner he reasonably believed to be in, or not opposed to, the best
interests of the Company; except that no indemnification under this subsection
shall be made in respect of any claim, issue or matter as to which such person
shall have been finally adjudged to be liable to the Company by a court of
competent jurisdiction, unless and only to the extent that the Court of Chancery
or the court in which such proceeding was brought shall determine upon
application that, despite the adjudication of liability but in view of all the
circumstances of the case, such person is fairly and reasonably entitled to
indemnity for such amounts which the Court of Chancery or such other court shall
deem proper; and

     4.3 Exception for Amounts Covered by Insurance. Notwithstanding the
foregoing, the Company shall not be obligated to indemnify the Indemnitee for
expenses or liabilities of any type whatsoever (including, but not limited to,
judgments, fines, ERISA excise taxes or penalties and amounts paid in
settlement) to the extent such have been paid directly to the Indemnitee by D&O
Insurance.

5. PARTIAL INDEMNIFICATION AND CONTRIBUTION.

     5.1 Partial Indemnification. If the Indemnitee is entitled under any
provision of this Agreement to indemnification by the Company for some or a
portion of any expenses or liabilities of any type whatsoever (including, but
not limited to, judgments, fines, ERISA excise taxes or penalties and amounts
paid in settlement) incurred by him in the investigation, defense, settlement or
appeal of a proceeding but is not entitled, however, to indemnification for all
of the total amount thereof, then the Company shall nevertheless indemnify the
Indemnitee for such total amount except as to the portion thereof to which the
Indemnitee is not entitled to indemnification.

     5.2 Contribution. If the Indemnitee is not entitled to the indemnification
provided in Section 4 for any reason, then in respect of any threatened, pending
or completed proceeding in which the Company is jointly liable with the
Indemnitee (or would be if joined in such proceeding), the Company shall
contribute to the amount of expenses (including attorneys' fees), judgments,
fines and amounts paid in settlement actually and reasonably incurred and paid
or payable by the Indemnitee in such proportion as is appropriate to reflect (i)
the relative benefits received by the Company on the one hand and the Indemnitee
on the other hand from the transaction from which such proceeding arose and (ii)
the relative fault of the Company on the one hand and of the Indemnitee on the
other hand in connection with the events which resulted in such expenses,
judgments, fines or settlement amounts, as well as any other relevant equitable
considerations. The relative fault of the Company on the one hand and of the
Indemnitee on the other hand shall be determined by reference to, among other
things, the parties' relative intent, knowledge, access to information and
opportunity to correct or prevent the circumstances resulting in such expenses,
judgments, fines or settlement amounts. The Company agrees that it would not be
just and equitable if contribution pursuant to this Section 5 were determined by
pro rata allocation or any other method of allocation which does not take
account of the foregoing equitable considerations.

6. MANDATORY ADVANCEMENT OF EXPENSES.

     6.1 Advancement. Subject to Section 9 below, the Company shall advance all
expenses incurred by the Indemnitee in connection with the investigation,
defense, settlement or appeal of any proceeding to which the Indemnitee is a
party or is threatened to be made a party by reason of the fact that the
Indemnitee is or was an agent of the Company or by reason of anything done or
not done by him in any such capacity. The Indemnitee hereby undertakes to
promptly repay such

<PAGE>

amounts advanced only if, and to the extent that, it shall ultimately be
determined that the Indemnitee is not entitled to be indemnified by the Company
under the provisions of this Agreement, the Certificate of Incorporation or
Bylaws of the Company, the General Corporation Law of Delaware or otherwise. The
advances to be made hereunder shall be paid by the Company to the Indemnitee
within thirty (30) days following delivery of a written request therefor by the
Indemnitee to the Company.

     6.2 Exception. Notwithstanding the foregoing provisions of this Section 6,
the Company shall not be obligated to advance any expenses to the Indemnitee
arising from a lawsuit filed directly by the Company against the Indemnitee if
an absolute majority of the members of the Board reasonably determines in good
faith, within thirty (30) days of the Indemnitee's request to be advanced
expenses, that the facts known to them at the time such determination is made
demonstrate clearly and convincingly that the Indemnitee acted in bad faith and
in a manner opposed to the best interests of the Company. If such a
determination is made, the Indemnitee may have such decision reviewed by another
forum, in the manner set forth in Sections 8.3, 8.4 and 8.5 hereof, with all
references therein to "indemnification" being deemed to refer to "advancement of
expenses," and the burden of proof shall be on the Company to demonstrate
clearly and convincingly that, based on the facts known at the time, the
Indemnitee acted in bad faith and in a manner opposed to the best interests of
the Company. The Company may not avail itself of this Section 6.2 as to a given
lawsuit if, at any time after the occurrence of the activities or omissions that
are the primary focus of the lawsuit, the Company has undergone a change in
control. For this purpose, a change in control shall mean a given person or
group of affiliated persons or groups increasing their beneficial ownership
interest in the Company by at least twenty (20) percentage points.

7. NOTICE AND OTHER INDEMNIFICATION PROCEDURES.

     7.1 Promptly after receipt by the Indemnitee of notice of the commencement
of or the threat of commencement of any proceeding, the Indemnitee shall, if the
Indemnitee believes that indemnification with respect thereto may be sought from
the Company under this Agreement, notify the Company of the commencement or
threat of commencement thereof.

     7.2 If, at the time of the receipt of a notice of the commencement of a
proceeding pursuant to Section 7.1 hereof, the Company has D&O Insurance in
effect, the Company shall give prompt notice of the commencement of such
proceeding to the insurers in accordance with the procedures set forth in the
respective policies. The Company shall thereafter take all necessary or
desirable action to cause such insurers to pay, on behalf of the Indemnitee, all
amounts payable as a result of such proceeding in accordance with the terms of
such D&O Insurance policies.

     7.3 In the event the Company shall be obligated to advance the expenses for
any proceeding against the Indemnitee, the Company, if appropriate, shall be
entitled to assume the defense of such proceeding, with counsel approved by the
Indemnitee (which approval shall not be unreasonably withheld), upon the
delivery to the Indemnitee of written notice of its election to do so. After
delivery of such notice, approval of such counsel by the Indemnitee and the
retention of such counsel by the Company, the Company will not be liable to the
Indemnitee under this Agreement for any fees of counsel subsequently incurred by
the Indemnitee with respect to the same proceeding, provided that: (a) the
Indemnitee shall have the right to employ his own counsel in any such proceeding
at the Indemnitee's expense; (b) the Indemnitee shall have the right to employ
his own counsel in connection with any such proceeding, at the expense of the
Company, if such counsel serves in a review, observer, advice and counseling
capacity and does not

<PAGE>

otherwise materially control or participate in the defense of such proceeding;
and (c) if (i) the employment of counsel by the Indemnitee has been previously
authorized by the Company, (ii) the Indemnitee shall have reasonably concluded
that there may be a conflict of interest between the Company and the Indemnitee
in the conduct of any such defense or (iii) the Company shall not, in fact, have
employed counsel to assume the defense of such proceeding, then the fees and
expenses of the Indemnitee's counsel shall be at the expense of the Company.

8. DETERMINATION OF RIGHT TO INDEMNIFICATION.

     8.1 To the extent the Indemnitee has been successful on the merits or
otherwise in defense of any proceeding referred to in Section 4.1 or 4.2 of this
Agreement or in the defense of any claim, issue or matter described therein, the
Company shall indemnify the Indemnitee against expenses actually and reasonably
incurred by him in connection with the investigation, defense or appeal of such
proceeding, or such claim, issue or matter, as the case may be.

     8.2 In the event that Section 8.1 is inapplicable, or does not apply to the
entire proceeding, the Company shall nonetheless indemnify the Indemnitee unless
the Company shall prove by clear and convincing evidence to a forum listed in
Section 8.3 below that the Indemnitee has not met the applicable standard of
conduct required to entitle the Indemnitee to such indemnification.

     8.3 The Indemnitee shall be entitled to select the forum in which the
validity of the Company's claim under Section 8.2 hereof that the Indemnitee is
not entitled to indemnification will be heard from among the following, except
that the Indemnitee can select a forum consisting of the stockholders of the
Company only with the approval of the Company:

     (a) A quorum of the Board consisting of directors who are not parties to
the proceeding for which indemnification is being sought;

     (b) The stockholders of the Company;

     (c) Legal counsel mutually agreed upon by the Indemnitee and the Board,
which counsel shall make such determination in a written opinion;

     (d) A panel of three arbitrators, one of whom is selected by the Company,
another of whom is selected by the Indemnitee and the last of whom is selected
by the first two arbitrators so selected; or

     (e) The Court of Chancery of Delaware or other court having jurisdiction of
subject matter and the parties.

     8.4 As soon as practicable, and in no event later than thirty (30) days
after the forum has been selected pursuant to Section 8.3 above, the Company
shall, at its own expense, submit to the selected forum its claim that the
Indemnitee is not entitled to indemnification, and the Company shall act in the
utmost good faith to assure the Indemnitee a complete opportunity to defend
against such claim.

     8.5 If the forum selected in accordance with Section 8.3 hereof is not a
court, then after the final decision of such forum is rendered, the Company or
the Indemnitee shall have the right to apply to the Court of Chancery of
Delaware, the court in which the proceeding giving rise to the Indemnitee's
claim for indemnification is or was pending or any other court of competent
jurisdiction, for the purpose of appealing the decision of such forum, provided
that such right is executed within sixty (60) days after the final decision of
such forum is rendered. If the forum selected in accordance with Section 8.3
hereof is a court, then the rights of the Company or the Indemnitee to appeal
any decision of such court shall be governed by the applicable laws and

<PAGE>

rules governing appeals of the decision of such court.

     8.6 Notwithstanding any other provision in this Agreement to the contrary,
the Company shall indemnify the Indemnitee against all expenses incurred by the
Indemnitee in connection with any hearing or proceeding under this Section 8
involving the Indemnitee and against all expenses incurred by the Indemnitee in
connection with any other proceeding between the Company and the Indemnitee
involving the interpretation or enforcement of the rights of the Indemnitee
under this Agreement unless a court of competent jurisdiction finds that each of
the material claims and/or defenses of the Indemnitee in any such proceeding was
frivolous or not made in good faith.

9. EXCEPTIONS. Any other provision herein to the contrary notwithstanding, the
Company shall not be obligated pursuant to the terms of this Agreement:

     9.1 Claims Initiated by Indemnitee. To indemnify or advance expenses to the
Indemnitee with respect to proceedings or claims initiated or brought
voluntarily by the Indemnitee and not by way of defense, except with respect to
proceedings specifically authorized by the Board or brought to establish or
enforce a right to indemnification and/or advancement of expenses arising under
this Agreement, the charter documents of the Company or any subsidiary or any
statute or law or otherwise, but such indemnification or advancement of expenses
may be provided by the Company in specific cases if the Board finds it to be
appropriate; or

     9.2 Unauthorized Settlements. To indemnify the Indemnitee hereunder for any
amounts paid in settlement of a proceeding unless the Company consents in
advance in writing to such settlement, which consent shall not be unreasonably
withheld; or

     9.3 Securities Law Actions. To indemnify the Indemnitee on account of any
suit in which judgment is rendered against the Indemnitee for an accounting of
profits made from the purchase or sale by the Indemnitee of securities of the
Company pursuant to the provisions of Section l6(b) of the Securities Exchange
Act of 1934 and amendments thereto or similar provisions of any federal, state
or local statutory law; or

     9.4 Unlawful Indemnification. To indemnify the Indemnitee if a final
decision by a court having jurisdiction in the matter shall determine that such
indemnification is not lawful. In this respect, the Company and the Indemnitee
have been advised that the Securities and Exchange Commission takes the position
that indemnification for liabilities arising under the federal securities laws
is against public policy and is, therefore, unenforceable and that claims for
indemnification should be submitted to appropriate courts for adjudication.

     9.5 Solicitation of Proxies. To indemnify the Indemnitee on account of any
solicitation of proxies by Indemnitee, or by a group of which he was or became a
member consisting of two or more persons that had agreed (whether formally or
informally and whether or not in writing) to act together for the purpose of
soliciting proxies, in opposition to any solicitation of proxies approved by the
Board of Directors.

     9.6 Breach of Agreement. To indemnify the Indemnitee for any activities by
Indemnitee that constitute a breach of or default under any agreement between
Indemnitee and the Company.

10. NON-EXCLUSIVITY. The provisions for indemnification and advancement of
expenses set forth in this Agreement shall not be deemed exclusive of any other
rights which the Indemnitee may have under any provision of law, the Company's
Certificate of Incorporation or

<PAGE>

Bylaws, the vote of the Company's stockholders or disinterested directors, other
agreements or otherwise, both as to action in the Indemnitee's official capacity
and to action in another capacity while occupying his position as an agent of
the Company, and the Indemnitee's rights hereunder shall continue after the
Indemnitee has ceased acting as an agent of the Company and shall inure to the
benefit of the heirs, executors and administrators of the Indemnitee.
