      other fiduciary holding securities under an employee benefit plan of the
      Company or a corporation owned directly or indirectly by the stockholders
      of the Company in substantially the same proportions as their ownership of
      stock of the Company, is or becomes the "beneficial owner" (as defined in
      Rule 13d-3 under the Act), directly or indirectly, of securities of the
      Company representing 20% or more of the total voting power represented by

      Company's stockholders was approved by a vote of at least two-thirds (2/3)
      of the directors then still in office who either were directors at the

      previously so approved, cease, for any reason, to constitute a majority of
      the Board of Directors, (iii) the stockholders of the Company approve a
      merger or consolidation of the Company with any other corporation, other

      Company.

            or a Claim authorized by the Board of Directors.

            "Expenses" means any expense incurred by Director as a result of a
      Claim or Claims made against him for Covered Acts including, without
      limitation, attorneys' fees and all other costs, expenses and obligations
      paid or incurred in connection with investigating, defending, being a
      witness in, or participating in (including on appeal), or preparing to
      defend, be a witness in, or participate in any Claim relating to any
      Covered Act, but shall not include Fines.

      2.    Maintenance of Directors' and Officers' Liability Insurance.

            (a) The Company hereby covenants and agrees that, so long as
      Director shall continue to serve as a director of the Company and
      thereafter so long as Director shall be subject to any Claim for any
      Covered Act, the Company, subject to Section 2(c), shall use its
      reasonable best efforts to maintain in full force and effect directors'
      and officers' liability insurance.

            (b) In all policies of directors' and officers' liability insurance
      maintained by the Company, Director shall be named as an insured in such a
      manner as to provide Director the same rights and benefits, subject to the
      same limitations, as are accorded to the Company's directors or officers
      most favorably insured by such policy.

            (c) The Company shall have no obligation to maintain directors' and
      officers' liability insurance if the Board of Directors of the Company
      determines in good faith that such insurance is not reasonably available,
      the premium costs for such insurance is disproportionate to the amount of
      coverage provided, or the coverage provided by such insurance is limited
      by exclusions so as to provide an insufficient benefit.

                                      -3-
<PAGE>

      3. Indemnification. The Company shall indemnify Director and hold him
harmless from any and all Losses, Expenses and Fines to the fullest extent
authorized, permitted or not prohibited (i) by the General Corporation Law of
the State of Delaware (the "GCL"), or any other applicable law (including
judicial, regulatory or administrative interpretations or readings thereof), the
Company's Restated Certificate of Incorporation or Amended and Restated Bylaws
as in effect on the date hereof, or (ii) by any amendment thereof or other
statutory provisions authorizing or permitting such indemnification that is
adopted after the date hereof, subject to the further provisions of this
Agreement. In the event that after the date hereof the Company provides any
greater right of indemnification, in any respect, to any other person serving as
an officer or director of the Company, then such greater right of
indemnification shall inure to the benefit of and shall be deemed to be
incorporated in this Agreement.

      4.    Excluded Coverage.

            (a) The Company shall have no obligation to indemnify Director for
      and hold him harmless from any Loss, Expense or Fine which has been
      Determined to constitute an Excluded Claim, provided that in the event of
      a Change in Control, then with respect to all matters thereafter arising
      concerning the rights of Director to indemnity payments and Expense
      advances under this Agreement, or under any other agreements, charter
      provisions or bylaws now or hereafter in effect relating to Claims for
      Covered Acts, a Determination with respect to an Excluded Claim shall be
      made only by a court of competent jurisdiction or by special, independent
      legal counsel selected by Director and approved by the Company (which
      approval shall not be unreasonably withheld), and who has not otherwise
      performed services for the Company or Director. In the event that Director
      and the Company are unable to agree on the selection of the special,
      independent legal counsel, such special, independent legal counsel shall
      be selected by lot from among at least five law firms designated by
      Director, having more than thirty-five (35) attorneys and having a rating
      of "av" or better in the then current Martindale-Hubbell Law Directory.
      Such selection shall be made in the presence of Director (and Director's
      legal counsel or either of them, as Director may elect). Such special,
      independent legal counsel, among other things, shall determine whether and
      to what extent Director would be permitted to be indemnified under
      applicable law and shall render its written opinion to the Company and
      Director to such effect.

            If there has been a Determination that the Company is not obligated
      to indemnify Director as a result of an Excluded Claim (whether by
      special, independent legal counsel or otherwise), Director shall have the
      right to commence litigation in any court in the State of Delaware having
      subject matter jurisdiction thereof, and in which venue is proper,
      challenging any such Determination; provided that the Company shall be
      entitled to be reimbursed by Director (who hereby agrees to reimburse the
      Company) for all such amounts theretofore paid with respect to such
      Excluded Claim (only upon a final judicial Determination that Director is
      not entitled to indemnification made with respect thereto as to which all
      rights of appeal therefrom have been exhausted or lapsed) and the Company
      shall be obligated to indemnify or advance any additional amounts to
      Director until such a judicial Determination has been made.

                                      -4-
<PAGE>

            (b) The Company shall use its best efforts to make any Determination
      contemplated herein promptly. Upon request by Director, in connection with
      any matter for which indemnification or reimbursement may be sought
      hereunder, the Company agrees to promptly make a Determination whether
      such matter constitutes an Excluded Claim. In this connection, the Company
      agrees:

                  (i) if the Determination is to be made by a majority of
            disinterested directors of the Company or a committee thereof, such
            Determination shall be made not later than fifteen (15) days after a
            written request for a Determination (a "Request") is delivered to
            the Company by Director;

                  (ii) if the Determination is to be made by special,
            independent legal counsel, such Determination shall be made not
            later than twenty (20) days after a Request is delivered to the
            Company by Director; and

                  (iii) if the Determination is to be made by the stockholders
            of the Company, such Determination shall be made not later than
            ninety (90) days after a Request is delivered to the Company by
            Director.

            The failure to make a Determination within the above-specified time
      periods shall constitute a Determination approving full indemnification or
      reimbursement of Director. All costs of making the Determination shall be
      borne solely by the Company.

            (c) The Company shall have no obligation to indemnify Director and
      hold him harmless for any Loss, Expense or Fine to the extent that
      Director is actually and finally reimbursed for such Loss, Expense or Fine
      by the Company pursuant to the Company's Bylaws or otherwise.

            (d) The Company shall have no obligation to indemnify Director and
      hold him harmless for any Fines to the extent that such indemnification is
      prohibited by the GCL.

      5.    Indemnification Procedures.

            (a) Promptly after receipt by Director of notice of the commencement
      of or the threat of commencement of any Claim, Director shall, if
      indemnification with respect thereto is being sought from the Company
      under this Agreement, notify the Company of the commencement thereof,
      provided that failure to so notify the Company shall not relieve the
      Company from any liability that it may have to Director under this
      Agreement unless such failure materially and adversely affects the rights
      of the Company thereunder.

            (b) If, at the time of the receipt of such notice, the Company has
      directors' and officers' liability insurance in effect, the Company shall
      give prompt and proper notice of the commencement of such Claim to the
      insurer. The Company shall thereafter take all necessary or desirable
      action to pay or to cause such insurer to pay, on behalf of Director,

                                      -5-
<PAGE>

      all Losses, Expenses and Fines payable as a result of such Claim in
      accordance with the terms of such policies.

            (c) To the extent the Company does not, at the time of the
      commencement of or the threat of commencement of such Claim, have
      applicable directors' and officers' liability insurance, or if the full
      amount of any Expenses arising out of such action, suit or Claim will not
      be payable under such insurance then in effect, the Company shall be
      obligated to pay the Expenses relating to any such Claim in advance of the
      final disposition thereof to the fullest extent permitted by law and the
      Company, if appropriate, shall be entitled to assume the defense of such
      Claim, with counsel satisfactory to Director, upon the delivery to
      Director of written notice of its election so to do. After delivery of
      such notice, the Company will not be liable to Director under this
      Agreement for any legal or other Expenses subsequently incurred by
      Director in connection with such defense other than reasonable costs of
      investigation, provided that Director shall have the right to employ his
      counsel in any such Claim but the fees and expenses of such counsel
      incurred after delivery of notice from the Company of its assumption of
      such defense shall be at the Director's expense, provided further that if
      (i) the employment of counsel by Director has been previously authorized
      by the Company, (ii) Director shall have reasonably concluded that there
      may be a conflict of interest between the Company and Director in the
      conduct of any such defense, or (iii) the Company shall not, in fact, have
      employed counsel to assume the defense of such action, the fees and
      expenses of counsel shall be at the expense of the Company.

            (d) All payments on account of the Company's indemnification
      obligations under this Agreement shall be made promptly, but in any event
      within thirty (30) days of Director's written request therefor, provided
      that all payments on account of the Company's obligations under Paragraph
      5(c) of this Agreement prior to the final disposition of any Claim, shall
      be made within ten (10) days of Director's written request therefor.

            (e) Director agrees that he will reimburse the Company for all
      Losses, Expenses and Fines paid by the Company on behalf of Director in
      connection with any Claim against Director in the event and only to the
      extent that a Determination shall have been made by a court in a final
      adjudication from which there is no further right of appeal that the
      Director is not entitled to be indemnified by the Company for such amounts
      because the Claim is an Excluded Claim or because Director is otherwise
      not entitled to payment under this Agreement.

      6. Final Determination; Settlement. The Company shall pay all Losses or
Fines for which Director is indemnified hereunder upon final determination
thereof. The Company shall have no obligation to indemnify Director under this
Agreement for any amounts paid in settlement of any Claim effected without the
Company's prior written consent. The Company shall not settle any claim in any
manner which would impose any Fine or any obligation on Director without
Director's written consent. Neither the Company nor Director shall unreasonably
withhold their consent to any proposed settlement.

                                      -6-
<PAGE>

      7. Rights Not Exclusive. The rights provided hereunder shall not be deemed
exclusive of any other rights to which Director may be entitled under any
charter provision, bylaw, agreement, vote of stockholders or of disinterested
directors or otherwise, both as to action in his official capacity and as to
action in any other capacity by holding such office, and shall continue after
Director ceases to serve the Company as a director. To the extent that a change
in the GCL (whether by statute or judicial decision) permits greater
indemnification by agreement than would be afforded currently under this
Agreement, it is the intent of the parties hereto that Director shall enjoy by
this Agreement the greater benefits so afforded by that change. Director's
rights under this Agreement shall not be diminished by any amendment to the
charter or bylaws, or of any other agreement or instrument to which Director is
not a party, and shall not diminish any other rights that Director now or in the
future has against the Company.

      8. Partial Indemnity. If Director is entitled under any provision of this
Agreement to indemnification by the Company for some, but not all, of Director's
Expenses, Fines or Losses, the Company shall indemnify Director for the portion
thereof to which Director is entitled.

      9.    Contribution.

            (a) Contribution Payment. To the extent the indemnification provided
for under any provision of this Agreement is Determined not to be permitted
under applicable law, the Company, in lieu of indemnifying Director, shall, to
the fullest extent permitted by law, contribute to the amount of any and all
Expenses, Fines or Losses incurred or paid by Director for which such
indemnification is not permitted. The amount the Company contributes shall be in
such proportion as is appropriate to reflect the relative fault of Director, on
the one hand, and of the Company and any and all other parties (including
officers and directors of the Company other than Director) who may be at fault
(collectively, including the Company, the "Third Parties"), on the other hand.

            (b) Relative Fault. The relative fault of the Third Parties and the
Director shall be determined (i) by reference to the relative fault of Director
as determined by the court or other governmental agency or (ii) to the extent
such court or other governmental agency does not apportion relative fault,
through a Determination after giving effect to, among other things, the relative
intent, knowledge, access to information, and opportunity to prevent or correct
the relevant events, of each party, and other relevant equitable considerations.
The Company and Director agree that it would not be just and equitable if
contribution were determined by pro rata allocation or by any other method of
allocation that does take account of the equitable considerations referred to in
this Section 9(b).

      10. No Presumption. For purposes of this Agreement, the termination of any
Claim by judgment, order, settlement (whether with or without court approval),
or conviction, or upon a plea of nolo contendere, or its equivalent, or an entry
of an order of probation prior to judgment shall not create a presumption (other
than any presumption arising as a matter of law that the parties may not
contractually agree to disregard) that Director did not meet any particular
standard of conduct or have any particular belief or that a court has determined
that indemnification is not permitted by applicable law.

                                      -7-

      11.   Enforcement.

            (a) Director's right to indemnification shall be enforceable by
      Director only in the state courts of the State of Delaware and shall be
      enforceable notwithstanding any adverse Determination. In any such action,
      if a prior adverse Determination has been made, the burden of proving that
      indemnification is required under this Agreement shall be on Director. The
      Company shall have the burden of proving that indemnification is not
      required under this Agreement if no prior adverse Determination shall have
      been made.

            (b) In the event that any action is instituted by Director under
      this Agreement to enforce or interpret any of the terms of this Agreement
      or to seek recovery under any directors' and officers' liability insurance
      policies maintained by the Company, Director shall be entitled to be paid
      all costs and expenses (including reasonable counsel fees) and, if
      requested by Director, the Company shall advance those costs and expenses
      to Director, that are incurred by Director with respect to such action,
      unless the court determines that each of the material assertions made by
      Director as a basis for such action were not made in good faith, were
      frivolously presented for improper purpose, without evidentiary support,
      or otherwise santionable under Federal Rule of Civil Procedure No. 11 or
      an analogous rule or law, and provided further, that if a court makes such
      a finding, Director shall reimburse the Company for all amounts previously
      advanced to Director pursuant to this Section 11(b).

      12. Severability. In the event that any provision of this Agreement is
determined by a court to require the Company to do or to fail to do an act which
is in violation of applicable law, such provision shall be limited or modified
in its application to the minimum extent necessary to avoid a violation of law,
and, as so limited or modified, such provision and the balance of this Agreement
shall be enforceable in accordance with its terms.

      13. Choice of Law. This Agreement shall be governed by and construed and
enforced in accordance with the laws of the State of Delaware.

      14. Consent to Jurisdiction. The Company and Director each hereby
irrevocably consent to the jurisdiction of the courts of the State of Delaware
for all purposes in connection with any action or proceeding that arises out of
or relates to this Agreement and agree that any action instituted under this
Agreement shall be brought only in the state courts of the State of Delaware.

      15. Successors and Assigns. This Agreement shall be (i) binding upon all
successors and assigns of the Company (including any transferee of all or
substantially all of its assets and any successor by merger or otherwise by
operation of law) and (ii) shall be binding on and inure to the benefit of the
heirs, personal representatives, and estate of Director.

      16. Amendment. No amendment, modification, termination or cancellation of
this Agreement shall be effective unless made in a writing signed by each of the
parties hereto.

                                      -8-

      17. Subrogation. In the event of payment under this Agreement, the Company
shall be subrogated to the extent of such payment to all of the rights of
recovery of the Director, who shall execute all instruments required and shall
do everything that may be necessary to secure such rights, including the
execution of such documents as may be necessary to enable the Company
effectively to bring suit to enforce such rights.

      18. Counterparts. This Indemnification Agreement may be executed in
multiple counterparts.

      IN WITNESS WHEREOF, the Company and Director have executed this Agreement
as of the day and year first above written to be effective for all purposes on
the Effective Date.
